Well established risk factors, recognized by the Royal College of Obstetricians and Gynecologists, are ethnicity, birth weight over 4 kg persistent occipital posterior position, null parity, induction of labor, shoulder dystocia, instrumental delivery. There are other risk factors that were suggested in the literature, but data are conflicting, such as prolonged second stage of labor, episiotomy and obesity. Objective: To evaluate third- and fourth-degree perineal rears rates and the impact of related risk factors on perineal tears in Ministry of health in Bahrain over 5 years (which includes Salmanyia Medical complex (SMC) and Jidhafs maternity hospital (JMH)). Methods: This retrospective descriptive cross-sectional study analyzed all vaginal deliveries from January 2015 to December 2019 in Obstetrics and Gynecology department in Salmanyia Medical Complex (the main hospital in Kingdom of Bahrain which received all kinds of cases including low and high risks) and Jidhafs Maternity Hospital (tertiary hospital which received only low risk cases), Kingdom of Bahrain. During the period of interest 33,694 records were identified. Data were extracted from observational recording from SMC and JMH labour registry books. Results: There was no statistically significant difference between groups according to age (p = 0.199). On the other hand, there was statistically significant higher cases of >40 weeks at gestational age, obesity > 35 kg/mr, vacuum delivery, pushing stage > 90 min, birth weight > 4 kg, head circumference > 34 cm, fetal length at birth > 50 cm, episiotomy and lower cases of nulliparity in study group compared to control group 16 (66.7%) vs. 13,805 (41.0%), 3 (12.5%) vs. 1448 (4.3%), 3 (12.5%) vs. 1414 (4.2%), 4 (16.7%) vs. 1751 (5.2%), 3 (12.5%) vs. 1751 (5.2%), 12 (50.0%) vs. 15,926 (47.3%), 15 (62.5%) vs. 20,135 (59.8%) and 17 (70.8%) vs. 29,024 (86.2%);(p = 0.027, 0.009, Conclusion: Gestational age > 40 weeks, obesity > 35 kg/mr, pushing stage > 90 min, birth weight > 4 kg, head circumference > 34 cm, fetal length at birth > 50 cm and using of vacuum increase incidence of 3rd and 4th degree perineal tears with vaginal delivery however maternal age and nulliparity have no significant role. Finally, episiotomy did not represent as protective factor for perineal damage. .展开更多

Soft tissue injuries, whether isolated or in combination with other injuries, form part of the frequent traumatic craniofacial injuries seen at the emergency department. The force of impact and the injury type is directly related to the severity of the injury sustained. This study aimed to analyze the etiological factors, prevalence, and management of oral and maxillofacial soft tissue injuries at the Komfo Anokye Teaching Hospital. Methods: This was a prospective study that involved children presenting with oral and maxillofacial injuries at the Accident and Emergency Department and the Oral and Maxillofacial Surgery unit of the Komfo Anokye Teaching Hospital in Kumasi between the period of April to October 2020 (6 months). Patient selection was by convenience sampling targeting all children with injuries who met the inclusion criteria. Inclusion criteria were children below the age of 18 years whose parents or caregivers consent to participation. Children with maxillofacial injuries as a result of burns were excluded from the study. Results: During the study period a total of 134 children were reviewed with oral and maxillofacial injuries at KATH. Of these, 107 (78.9%) were recorded cases of orofacial soft tissue injuries. There were 63 (58.9%) males and 44 (41.1%) females and the male-to-female ratio was 1.5:1. The age range of patients studied was 8 months – 17 years, with mean age ± SD being 9.5 ± 5.3 years. Road Traffic Crash (50.5%) was the most common etiology of which Motor cycle crash constituted 24.3% and Pedestrian knockdown was 19.6%. Falls (42.1%) were the next most common etiology. The lips (19.8%) and the forehead (18.5%) were the most frequently injured sites on the face whiles the tongue (3.3%) had the most injuries intraorally. Laceration (45.7%) was the most frequent injury reviewed, followed by abrasions (35.8%). Most of the soft tissue injuries underwent primary closure (56.3%). A complication rate of 21.2% was recorded in this study and hypertrophic scarring (11.3%) was the most observed.展开更多

Vision improved to normal in all the eyes following surgical/ medical/optical treatment. ·CONCLUSION:Evidence of penetrating injury (because of thorns) and blunt injury (because of weight) can be seen in the eyes when durian fruit falls on the face. Vision can be recovered fully with immediate and appropriate treatment in these cases. The ocular injuries can be prevented by educating the public to wear protective metal frame wide goggles and not to sleep/take rest under the durian tree.展开更多

METHODS: A retrospective review of all old canalicular laceration repairs from Jan. 1, 2008 to Dec. 30, 2015 was performed. Analyzed data included demographics, mechanisms of injury, the time from injury to repair, causes for delayed repair, old associated injuries, the types of surgery, and the effects of repair using canaliculus anastomosis combined with bicanalicular stent intubation. RESULTS: Totally 148 patients with old canalicular laceration received surgical repair and were enrolled. The mean age at presentation was 32.52 years old (ranged from 3 to 63 years old). The 110 patients (74.32%) were male and 127 patients (85.81%) were adults (__.18 years old). The old upper, lower, and bicanalicular lacerations were found in 5 (3.38%), 39 (26.35%), and 104 patients (70.27%), respectively. The mechanism of old injury was primarily due to motor vehicle accidents (n=53, 35.81%). The mean time from injury to repair was 43.61mo (ranged from 1 to 360mo). Associated old ocular and orbit injuries were found in 65 patients (43.92%), and chronic dacryocystitis in 18 patients (12.16%). The main cause of delayed repair was that doctors or patients didn't pay attention to the canalicular laceration because of the concurrent severe injuries (n=71, 47.97%). Totally 136 patients (91.89%) with old canalicular laceration underwent canaliculus anastomosis combined with bicanalicular stent intubation. In all of them, 20 patients (13.51%) were combined with dacryocystorhinostomy. In these cases, 132 patients (97.06%) attained anatomic success, 121 patients (88.97%)reported no epiphora (functional success), 11 patients (8.09%) reported significant epiphora anesis (functional improvement), and 4 (2.94%) reported no significant anesis (functional failure). Rates of anatomic success and functional success were significantly correlated with different canaliculus involved. However, rates of anatomic success and functional success were not significantly affected by the time from injury to repair. CONCLUSION: The canalicular anastomosis combined with bicanalicular stent intubation could act as an effective therapeutics for old canalicular laceration.展开更多

It is however an important complication following TIPS, which remains one of the most technically challenging interventional procedures performed. In addition to laceration, a number of complications regarding bleeding and perforation are well described following TIPS procedures. We feel the adoption of techniques such as ours and that of other authors described in the literature using an ultrasoundguided percutaneous transhepatic approach with a small caliber needle provides a safer and less traumatic procedure and should reduce complications of bleeding and almost completely eliminate the risk of liver laceration. Our procedure was successfully performed under conscious sedation rather than general anaesthesia further reducing the overall procedural risk to the patient.展开更多

METHODS:We conducted a retrospective study to review medical files of children admitted with blunt pancreatic injuries to the Maternity and Children Hospital Al-Madina Al-Munawwarah, Kingdom of Saudi Arabia. The demographic details and mechanisms of injury were recorded. From the database of the Picture Archiving and Communication System of the radiology department, multidetector computed tomography (MDCT) images of the pancreatic injuries, severity, type of injuries and grading of pancreatic injuries were established. RESULTS:Seven patients were recruited in this study over a period of 5 years; 5 males and 2 females with a mean age of 7 years (age range 5-12 years). Fall from height was the most frequent mechanism of injury, reported in 5 (71%), followed by road traffic accident (1 patient, 14%) and cycle handlebar (1 patient, 14%) injuries. According to the American Association for the Surgery of Trauma grading system, 1 (14%) patient sustained Grade Ⅰ, 1 (14%) Grade Ⅱ, 3 (42%) GradeⅢ and 2 (28%) patients were found to have Grade Ⅴ pancreatic injuries. This indicated a higher incidence of severe pancreatic injuries; 5 (71.4%) patients were reported to have Grade Ⅲ and higher on the injury scale. Three (42%) patients had associated abdominal organ injuries. CONCLUSION: Pediatric pancreatic injuries due to blunt abdominal trauma are rare. The majority of the patients sustained extensive pancreatic injuries. MDCT findings are helpful and reliable in diagnosing and grad- ing the pancreatic injuries.展开更多

The patients were divided into two groups. Group 1 consisted of patients who had hepatic injuries only. Group 2 consisted of patients who also had associated injuries outside the liver.RESULTS: Seven(30.4%) patients in group 1 and 10(28.6%) patients in group 2 received non-operative management; the rest underwent operation. Blunt trauma occurred in 82.8%(48/58) of the patients and penetrative trauma in 17.2%(10/58). A higher injury severity score(ISS) was observed in group 2(median 45 vs 25, P < 0.0001). More patients in group 1 were hemodynamically stable(65.2% vs 37.1%, P = 0.036). Other parameters were comparable between groups. Group 1 had better 30-d survival(91.3% vs 71.4%, P = 0.045). On multivariate analysis using the logistic regression model, ISS was found to be associated with mortality(P = 0.004, hazard ratio = 1.035, 95%CI:CONCLUSION: Liver trauma patients with multiple injuries are relatively unstable on presentation. Despite a higher ISS in group 2, non-operative management was possible for selected patients. Associated injuries outside the liver usually account for morbidity and mortality.展开更多

Results revealed that at 2 hours after cerebral contusion and laceration injury, aquaporin 4 expression significantly increased, brain water content and blood-brain barrier permeability increased, and the number of pinocytotic vesicles in cerebral microvascular endothelia cells increased. In addition, the mitochondrial accumulation was observed. As contusion and laceration injury became aggravated, aquaporin 4 expression continued to increase, brain water content and blood-brain barrier permeability gradually increased, brain capillary endothelial cells and astrocytes swelled, and capillary basement membrane injury gradually increased. The above changes were most apparent at 12 hours after injury, after which they gradually attenuated. Aquaporin 4 expression positively correlated with brain water content and the blood-brain barrier index. Our experimental findings indicate that increasing aquaporin 4 expression and blood-brain barrier permeability after cerebral contusion and laceration injury in humans is involved in the formation of brain edema.展开更多

The patients were examined using UBM, and disease-specific features of the UBM images were noted.· RESULTS: UBM imaging of lacrimal canaliculi in chronic canaliculitis patients showed obvious ectasia of the lacrimal canalicular lumen. Dot-like moderate echoic signals were detected on some ectatic lumina of the lacrimal canaliculus. Some lumen-like structures of the lower lacrimal canaliculus were observed in 2(2 eyes, 2canaliculi) of the 9 patients(12 eyes, 18 canaliculi) with congenital absence of the lacrimal canaliculus. Of the 18patients(18 eyes, 18 canaliculi) with previous lacrimal canalicular laceration, the lacerated end on the nasal side of the lacrimal canaliculus was detected only in 14patients(14 eyes, 14 canaliculi).·CONCLUSION: UBM can be used to evaluate lacrimal canalicular diseases and can provide an imaging basis for the diagnosis of lacrimal canalicular diseases.展开更多

The patient had a history of a giant hepatic cavernous hemangioma. Emergency exploratory laparotomy was performed for suspected intra-abdominal bleeding with abdominal compartment syndrome, and more than 4 liters of blood and blood clots were removed. An active bleeding laceration (5 cm) of a hepatic cavernous hemangioma was detected in segment III of the liver. The bleeding was controlled by sutures, Teflon patches and tamponade. The abdomen was closed temporarily using the vacuum-assisted method. Because of the presence of persistent fresh blood through abdominal drainage at a rate of 〉1 L/h, splenectomy was performed to control the bleeding again by sutures and Teflon patches. Finally, the abdomen was closed using a biologic mesh. The patient was discharged home 30 days after trauma. Bleeding of trauma-caused hepatic hemangioma is rare, but splenic injury due to blunt abdominal trauma is common. An in-depth investigation is necessary to avoid second intervention.展开更多

Exclusion criteria included patients with lacerations for more than 12 hours, immunocompromized patients, patients given antibiotics, and patients with gross contamination, bites or crush injuries. Wound infection was defined as clinical infection at a follow-up visit(10–14 days) or wound was treated with antibiotics. Patient satisfaction was also measured using a visual analogue scale 1–10, asking the patients about wound appearance. Demographic data and wound characteristics were compared between the infected and non-infected wounds. The infection rates were also compared between patients who received prophylactic antibiotics and those who did not. The results were presented with medians and quartiles or percentages with 95% confidence intervals(CI).RESULTS: In the 125 patients with SHL [median age: 28(18, 43); range: 1–102 years old; 36% female], 44(35%, 95% CI: 27%–44%) were given antibiotics in the ED. Wound infection was reported in 6 patients(4.8%, 95% CI: 2%–10%). Age, gender, history of diabetes and wound closure were not associated with wound infection(P>0.05). The infection rate was not significantly different between patients with or without antibiotic prophylaxis [7%(3/44), 95% CI: 2%–10% vs. 4%(3/81), 95% CI: 1%–11%, P=0.66]. Patient's satisfaction with appearance ofinfected and non-infected wounds were significantly different [7.5(6, 8) vs. 9(8, 10), P=0.01].CONCLUSION: Approximately 5% of simple hand lacerations become infected. Age, gender, diabetes, prophylactic antibiotics and closure technique do not affect the risk ofinfection.展开更多

Therefore, interventions that increase the probability of intact perineum are necessary. The aim of study was to determine the effect of perineal massage with a sterile lubricant on the incidence of episiotomy and perinea laceration. Materials: This clinical trial study was performed on 145 nulliparous women who referred to Amol Emam Ali teaching center for normal delivery. They were randomly participating in interventional group (massage with lubricant) (45 cases) or control group (100 cases). In massage group when they progressed to full dilatation of the cervix, the midwife inserted two fingers inside vagina and using a sweeping motion gently stretched the perineum with lubricant 5 up to 10 minutes, in and between mother’s pushing in the second stage of labour. In control group just Ritgen Maneuver was applied. At last, we compared the rate of intact perineum, episiotomy and laceration, mean duration of the second stage of labor and Apgar score in 1 and 5 minutes between two groups. Statistical analyses were performed using t-test, Chi Square to determine potentially significant associations, and a p value less than 0.05 was considered significant. Results: The incidences of intact perineum, episiotomy and laceration were 22.2% (10), 44.4% (20), 33.3% (15) respectively in interventional group. In control group, intact perineum, episiotomy and laceration were: 20.2% (20), 49.3% (71), 28.3% (28) respectively. This difference was not statis- tically significant. Rate of first-degree laceration was 33.3% (15) in massage group, while this percent was 28.3% (28) in control group. This difference was not statistically significant. In massage and control groups, second, third and fourth-degree lacerations did not occur. Conclusion: The results showed that massage with a sterile lubricant provides no apparent and significant advantage or disadvantage in reducing perineal trauma. Therefore, the use of massage as technique for perineal control is safe based on labour criteria and woman’s preference during delivery.展开更多

Method: A retrospective case-control study of all patients with primary postpartum haemorrhage from January 1, 2001 to December 31, 2010 at Olabisi Onabanjo University Teaching Hospital, Sagamu, Nigeria. Result: In the period under review, 272 cases of primary postpartum haemorrhage were documented while there were a total of 5929 deliveries, giving an incidence of 1 in 26 (25.6%). The average blood loss in the cases reviewed was 1550 mls whilst in the controls, the average blood loss was 200 mls. There was statistical significant difference between the grandmultiparous cases and grandmultiparous controls (58.4% versus 16.5%, OR = 6.74, p < 0.05), suggesting that grandmultiparity may be an implicated factor in primary postpartum haemorrhage. In the unbooked cases, retained placenta was the major cause of primary postpartum haemorrhage constituting 109 (51.7%), whereas in booked cases, uterine atony contributed 70.5% to primary postpartum haemorrhage. Four maternal deaths were recorded giving a case fatality rate of 1.5%;all were unbooked. Conclusion: Postpartum haemorrhage ranks high in the list of causes of maternal death and the case fatality rate can be very high. Prevention is the key to reducing the incidence of PPH and its sequale, with preventive measures based upon the identification of risk factors, surveillance of women at risk and seemingly not at risk and avoidance of procedure during delivery which could potentially result in complications.展开更多

PSI-15 was created to study accidental punctures and lacerations(APL), but PSI-15 may underestimate APLs in populations of patients. This study compares PSI-15 with a more inclusive approach using a novel composite of secondary diagnostic and procedural codes. Methods: We used Nationwide Inpatient Sample(NIS) data(20 0 0–2012) from AHRQ’s Healthcare Cost and Utilization Project(H-CUP). We analyzed PSI-15-positive and-negative cholecystectomies. Cross tabulations identified codes that were significantly more frequent among PSI-15-positive cases; these secondary diagnostic and procedural codes were selected as candidate members of a composite marker(CM) of APL. We chose cholecystectomy patients for study because this is one of the most common general operations, and the large size of NIS allows for meaningful analysis of infrequent occurrences such as APL rates. Results: CM identified 1.13 times more APLs than did PSI-15. Patients with CM-detected APLs were significantly older and had worse mortality, comorbidities, lengths of stay, and charges than those detected with PSI-15. Further comparison of these two approaches revealed that time-series analysis for both APL markers revealed parallel trends, with inflections in 2007, and lowest APL rates in July. Conclusions: Although CM may yield more false positives, it appears more inclusive, identifying more clinically significant APLs, than PSI-15. Both measures presented similar trends over time, arguing against inflation in PSI-15 reporting. While arguably less specific, CM may increase sensitivity for detecting APL events during cholecystectomies. These results may inform the interpretation of other large population studies of APLs following abdominal operations.展开更多
Results of extended and refined optical identification of 181 radio/X-ray sources in the RASS-Green Bank (RGB) catalog are presented (Brinkmann et al. 1997) which have been spectroscopically observed in the Sloan ...Results of extended and refined optical identification of 181 radio/X-ray sources in the RASS-Green Bank (RGB) catalog are presented (Brinkmann et al. 1997) which have been spectroscopically observed in the Sloan Digital Sky Survey (SDSS) DR5. The SDSS spectra of the optical counterparts are modeled in a careful and selfconsistent way by incorporating the host galaxy's starlight. Optical emission line parameters are presented, which are derived accurately and reliably, along with the radio 1.4- 5 GHz spectral indices estimated using (non-simultaneous) archival data. For 72 sources, the identifications are presented for the first time. It is confirmed that the majority of strong radio/X-ray emitters are radio-loud active galactic nuclei (AGNs), particularly blazars. Taking advantage of the high spectral quality and resolution and our refined spectral modeling, we are able to disentangle narrow line radio galaxies (NLRGs), as vaguely termed in most previous identification work, into Seyfert II galaxies and LINERs (low-ionization nuclear emission regions), based on the standard emission line diagnostics. The NLRGs in the RGB sample, mostly belonging to 'weak line radio galaxies', are found to have optical spectra consistent predominantly with LINERs, and only a small fraction with Seyfert II galaxies. A small number of LINERs have radio power as high as 10623 - 10^26 W Hz^- 1 at 5 GHz, being among the strongest radio emitting LINERs known so far. Two sources are identified with radio-loud narrow line Seyfert 1 galaxies (NLS 1 s), a class of rare objects. The presence is also confirmed of flat-spectrum radio quasars whose radio-optical-X-ray effective spectral indices are similar to those of High-energy peaked BL Lacs (HBLs), as suggested by Padovani et al., although it is still a debate as to whether this is the case for their actual spectral energy distributions.展开更多
文摘Background: Perineal trauma and vaginal laceration are considered a common complication associated with vaginal delivery. Well established risk factors, recognized by the Royal College of Obstetricians and Gynecologists, are ethnicity, birth weight over 4 kg persistent occipital posterior position, null parity, induction of labor, shoulder dystocia, instrumental delivery. There are other risk factors that were suggested in the literature, but data are conflicting, such as prolonged second stage of labor, episiotomy and obesity. Objective: To evaluate third- and fourth-degree perineal rears rates and the impact of related risk factors on perineal tears in Ministry of health in Bahrain over 5 years (which includes Salmanyia Medical complex (SMC) and Jidhafs maternity hospital (JMH)). Methods: This retrospective descriptive cross-sectional study analyzed all vaginal deliveries from January 2015 to December 2019 in Obstetrics and Gynecology department in Salmanyia Medical Complex (the main hospital in Kingdom of Bahrain which received all kinds of cases including low and high risks) and Jidhafs Maternity Hospital (tertiary hospital which received only low risk cases), Kingdom of Bahrain. During the period of interest 33,694 records were identified. Data were extracted from observational recording from SMC and JMH labour registry books. Results: There was no statistically significant difference between groups according to age (p = 0.199). On the other hand, there was statistically significant higher cases of >40 weeks at gestational age, obesity > 35 kg/mr, vacuum delivery, pushing stage > 90 min, birth weight > 4 kg, head circumference > 34 cm, fetal length at birth > 50 cm, episiotomy and lower cases of nulliparity in study group compared to control group 16 (66.7%) vs. 13,805 (41.0%), 3 (12.5%) vs. 1448 (4.3%), 3 (12.5%) vs. 1414 (4.2%), 4 (16.7%) vs. 1751 (5.2%), 3 (12.5%) vs. 1751 (5.2%), 12 (50.0%) vs. 15,926 (47.3%), 15 (62.5%) vs. 20,135 (59.8%) and 17 (70.8%) vs. 29,024 (86.2%);(p = 0.027, 0.009, Conclusion: Gestational age > 40 weeks, obesity > 35 kg/mr, pushing stage > 90 min, birth weight > 4 kg, head circumference > 34 cm, fetal length at birth > 50 cm and using of vacuum increase incidence of 3rd and 4th degree perineal tears with vaginal delivery however maternal age and nulliparity have no significant role. Finally, episiotomy did not represent as protective factor for perineal damage. .
文摘Background: Maxillofacial injury may vary from simple soft tissue lacerations to complex fractures of the orofacial region. Soft tissue injuries, whether isolated or in combination with other injuries, form part of the frequent traumatic craniofacial injuries seen at the emergency department. The force of impact and the injury type is directly related to the severity of the injury sustained. This study aimed to analyze the etiological factors, prevalence, and management of oral and maxillofacial soft tissue injuries at the Komfo Anokye Teaching Hospital. Methods: This was a prospective study that involved children presenting with oral and maxillofacial injuries at the Accident and Emergency Department and the Oral and Maxillofacial Surgery unit of the Komfo Anokye Teaching Hospital in Kumasi between the period of April to October 2020 (6 months). Patient selection was by convenience sampling targeting all children with injuries who met the inclusion criteria. Inclusion criteria were children below the age of 18 years whose parents or caregivers consent to participation. Children with maxillofacial injuries as a result of burns were excluded from the study. Results: During the study period a total of 134 children were reviewed with oral and maxillofacial injuries at KATH. Of these, 107 (78.9%) were recorded cases of orofacial soft tissue injuries. There were 63 (58.9%) males and 44 (41.1%) females and the male-to-female ratio was 1.5:1. The age range of patients studied was 8 months – 17 years, with mean age ± SD being 9.5 ± 5.3 years. Road Traffic Crash (50.5%) was the most common etiology of which Motor cycle crash constituted 24.3% and Pedestrian knockdown was 19.6%. Falls (42.1%) were the next most common etiology. The lips (19.8%) and the forehead (18.5%) were the most frequently injured sites on the face whiles the tongue (3.3%) had the most injuries intraorally. Laceration (45.7%) was the most frequent injury reviewed, followed by abrasions (35.8%). Most of the soft tissue injuries underwent primary closure (56.3%). A complication rate of 21.2% was recorded in this study and hypertrophic scarring (11.3%) was the most observed.
文摘·AIM:To report various ocular injuries caused by durian fruit. ·METHODS:Three cases of ocular injuries were described in young patients, due to accidental fall of durian fruit on the forehead and face, while they were taking rest/sleeping /playing under the durian tree. ·RESULTS:The ocular injuries observed were lacerating injury of cornea with iris incarceration, hyphema, superficial penetrating injury of sclera and angle recession glaucoma in the right eye of first patient; lacerating injury of cornea with iris prolapse in the left eye of second patient; subconjunctival haemorrhage, traumatic mydriasis and superficial penetrating injury of sclera, commotion retinopathy and macular edema in the left eye of third patient. Vision improved to normal in all the eyes following surgical/ medical/optical treatment. ·CONCLUSION:Evidence of penetrating injury (because of thorns) and blunt injury (because of weight) can be seen in the eyes when durian fruit falls on the face. Vision can be recovered fully with immediate and appropriate treatment in these cases. The ocular injuries can be prevented by educating the public to wear protective metal frame wide goggles and not to sleep/take rest under the durian tree.

文摘AIM: To investigate the epidemiology and surgical outcomes of old canalicular laceration and analyze the variables impacting on the prognosis of reparation. METHODS: A retrospective review of all old canalicular laceration repairs from Jan. 1, 2008 to Dec. 30, 2015 was performed. Analyzed data included demographics, mechanisms of injury, the time from injury to repair, causes for delayed repair, old associated injuries, the types of surgery, and the effects of repair using canaliculus anastomosis combined with bicanalicular stent intubation. RESULTS: Totally 148 patients with old canalicular laceration received surgical repair and were enrolled. The mean age at presentation was 32.52 years old (ranged from 3 to 63 years old). The 110 patients (74.32%) were male and 127 patients (85.81%) were adults (__.18 years old). The old upper, lower, and bicanalicular lacerations were found in 5 (3.38%), 39 (26.35%), and 104 patients (70.27%), respectively. The mechanism of old injury was primarily due to motor vehicle accidents (n=53, 35.81%). The mean time from injury to repair was 43.61mo (ranged from 1 to 360mo). Associated old ocular and orbit injuries were found in 65 patients (43.92%), and chronic dacryocystitis in 18 patients (12.16%). The main cause of delayed repair was that doctors or patients didn't pay attention to the canalicular laceration because of the concurrent severe injuries (n=71, 47.97%). Totally 136 patients (91.89%) with old canalicular laceration underwent canaliculus anastomosis combined with bicanalicular stent intubation. In all of them, 20 patients (13.51%) were combined with dacryocystorhinostomy. In these cases, 132 patients (97.06%) attained anatomic success, 121 patients (88.97%)reported no epiphora (functional success), 11 patients (8.09%) reported significant epiphora anesis (functional improvement), and 4 (2.94%) reported no significant anesis (functional failure). Rates of anatomic success and functional success were significantly correlated with different canaliculus involved. However, rates of anatomic success and functional success were not significantly affected by the time from injury to repair. CONCLUSION: The canalicular anastomosis combined with bicanalicular stent intubation could act as an effective therapeutics for old canalicular laceration.
文摘AIM:To evaluate the efficacy and safety of one-stitch anastomosis through the skin with bicanalicular silicone tube intubation in repairing of bicanalicular laceration.METHODS:The clinical data of 15 consecutive patients with both superior and inferior canalicular laceration in one eye who underwent surgical repair using one-stitch anastomosis through the skin and bicanalicular stent were retrospective studied.All the operations were performed under surgical microscope,5-0 silk sutures were used and were with bicanalicular silicone tube(diameter was 8mm) intubation,for one lacerated canaliculi one-stitch anastomosis through the skin.The stents were left in place for 3 months postoperatively and then removed.The follow-up period was 3-36 months(average 14 months). RESULTS:In 15 patients,13 patients were cured entirely,1 patient was meliorated,1 patient with no effects.All patients had got good recovery of eyelid laceration with no traumatic deformity in eyelid and canthus.Complication was seen in one case,for not followed the doctor’s guidance to come back to hospital to had the suture removed on the 7thday after operation,when he came at the 15thday,the inferior canalicular wall and eyelid skin were corroded by the suture caused 2mm wound,and the inside silicone tube was exposed,a promptly repair with 10-0 nylon suture was done,the wound healed in a week.There were no early tube protrusions and punctal slits in the patients.CONCLUSION:One-stitch anastomosis through the skin with bicanalicular silicone tube intubation is a good method in repair of bicanalicular laceration in one eye,the cut ends can be anastomosed directly,and with excellent cosmetic results,it is acceptable for the patients.For there is no suture remained in the wound permanently,so there is no suture-related granuloma which may cause obstruction or stenosis of canaliculi.It is simple,economical,effective and safe.
文摘Delayed liver laceration following transjugular intrahepatic portosystemic shunt (TIPS) is a serious and likely underdiagnosed complication. It is however an important complication following TIPS, which remains one of the most technically challenging interventional procedures performed. In addition to laceration, a number of complications regarding bleeding and perforation are well described following TIPS procedures. We feel the adoption of techniques such as ours and that of other authors described in the literature using an ultrasoundguided percutaneous transhepatic approach with a small caliber needle provides a safer and less traumatic procedure and should reduce complications of bleeding and almost completely eliminate the risk of liver laceration. Our procedure was successfully performed under conscious sedation rather than general anaesthesia further reducing the overall procedural risk to the patient.
文摘AIM:To evaluate the efficacy of computed tomography scan in diagnosing and grading the pattern of pancreatic injuries in children. METHODS:We conducted a retrospective study to review medical files of children admitted with blunt pancreatic injuries to the Maternity and Children Hospital Al-Madina Al-Munawwarah, Kingdom of Saudi Arabia. The demographic details and mechanisms of injury were recorded. From the database of the Picture Archiving and Communication System of the radiology department, multidetector computed tomography (MDCT) images of the pancreatic injuries, severity, type of injuries and grading of pancreatic injuries were established. RESULTS:Seven patients were recruited in this study over a period of 5 years; 5 males and 2 females with a mean age of 7 years (age range 5-12 years). Fall from height was the most frequent mechanism of injury, reported in 5 (71%), followed by road traffic accident (1 patient, 14%) and cycle handlebar (1 patient, 14%) injuries. According to the American Association for the Surgery of Trauma grading system, 1 (14%) patient sustained Grade Ⅰ, 1 (14%) Grade Ⅱ, 3 (42%) GradeⅢ and 2 (28%) patients were found to have Grade Ⅴ pancreatic injuries. This indicated a higher incidence of severe pancreatic injuries; 5 (71.4%) patients were reported to have Grade Ⅲ and higher on the injury scale. Three (42%) patients had associated abdominal organ injuries. CONCLUSION: Pediatric pancreatic injuries due to blunt abdominal trauma are rare. The majority of the patients sustained extensive pancreatic injuries. MDCT findings are helpful and reliable in diagnosing and grad- ing the pancreatic injuries.
文摘AIM: To review the outcomes of liver trauma in patients with hepatic injuries only and in patients with associated injuries outside the liver.METHODS: Data of liver trauma patients presented to our center from January 2003 to October 2013 were reviewed. The patients were divided into two groups. Group 1 consisted of patients who had hepatic injuries only. Group 2 consisted of patients who also had associated injuries outside the liver.RESULTS: Seven(30.4%) patients in group 1 and 10(28.6%) patients in group 2 received non-operative management; the rest underwent operation. Blunt trauma occurred in 82.8%(48/58) of the patients and penetrative trauma in 17.2%(10/58). A higher injury severity score(ISS) was observed in group 2(median 45 vs 25, P < 0.0001). More patients in group 1 were hemodynamically stable(65.2% vs 37.1%, P = 0.036). Other parameters were comparable between groups. Group 1 had better 30-d survival(91.3% vs 71.4%, P = 0.045). On multivariate analysis using the logistic regression model, ISS was found to be associated with mortality(P = 0.004, hazard ratio = 1.035, 95%CI:CONCLUSION: Liver trauma patients with multiple injuries are relatively unstable on presentation. Despite a higher ISS in group 2, non-operative management was possible for selected patients. Associated injuries outside the liver usually account for morbidity and mortality.
文摘This study aimed to investigate aquaporin 4 expression and the ultrastructure of the blood-brain barrier at 2-72 hours following cerebral contusion injury, and correlate these changes to the formation of brain edema. Results revealed that at 2 hours after cerebral contusion and laceration injury, aquaporin 4 expression significantly increased, brain water content and blood-brain barrier permeability increased, and the number of pinocytotic vesicles in cerebral microvascular endothelia cells increased. In addition, the mitochondrial accumulation was observed. As contusion and laceration injury became aggravated, aquaporin 4 expression continued to increase, brain water content and blood-brain barrier permeability gradually increased, brain capillary endothelial cells and astrocytes swelled, and capillary basement membrane injury gradually increased. The above changes were most apparent at 12 hours after injury, after which they gradually attenuated. Aquaporin 4 expression positively correlated with brain water content and the blood-brain barrier index. Our experimental findings indicate that increasing aquaporin 4 expression and blood-brain barrier permeability after cerebral contusion and laceration injury in humans is involved in the formation of brain edema.
文摘· AIM: To evaluate the application of ultrasound biomicroscopy(UBM) in the examination of lacrimal canalicular diseases, and to investigate UBM image characteristics of lacrimal canaliculi in disease states.·METHODS: Sixty cases(63 eyes, 69 canaliculi) of lacrimal canalicular diseases were enrolled that included32 patients(32 eyes, 32 canaliculi) with chronic lacrimal canaliculitis, 18 patients(18 eyes, 18 canaliculi) with previous lacrimal canalicular laceration, 9 patients(12eyes, 18 canaliculi) with congenital absence of lacrimal puncta and canaliculi, and 1 case(1 eye, 1 canaliculus)of canalicular mass. The patients were examined using UBM, and disease-specific features of the UBM images were noted.· RESULTS: UBM imaging of lacrimal canaliculi in chronic canaliculitis patients showed obvious ectasia of the lacrimal canalicular lumen. Dot-like moderate echoic signals were detected on some ectatic lumina of the lacrimal canaliculus. Some lumen-like structures of the lower lacrimal canaliculus were observed in 2(2 eyes, 2canaliculi) of the 9 patients(12 eyes, 18 canaliculi) with congenital absence of the lacrimal canaliculus. Of the 18patients(18 eyes, 18 canaliculi) with previous lacrimal canalicular laceration, the lacerated end on the nasal side of the lacrimal canaliculus was detected only in 14patients(14 eyes, 14 canaliculi).·CONCLUSION: UBM can be used to evaluate lacrimal canalicular diseases and can provide an imaging basis for the diagnosis of lacrimal canalicular diseases.
文摘A 41-year-old woman with blunt abdominal trauma due to a motor vehicle accident presented to our emergency department. The patient had a history of a giant hepatic cavernous hemangioma. Emergency exploratory laparotomy was performed for suspected intra-abdominal bleeding with abdominal compartment syndrome, and more than 4 liters of blood and blood clots were removed. An active bleeding laceration (5 cm) of a hepatic cavernous hemangioma was detected in segment III of the liver. The bleeding was controlled by sutures, Teflon patches and tamponade. The abdomen was closed temporarily using the vacuum-assisted method. Because of the presence of persistent fresh blood through abdominal drainage at a rate of 〉1 L/h, splenectomy was performed to control the bleeding again by sutures and Teflon patches. Finally, the abdomen was closed using a biologic mesh. The patient was discharged home 30 days after trauma. Bleeding of trauma-caused hepatic hemangioma is rare, but splenic injury due to blunt abdominal trauma is common. An in-depth investigation is necessary to avoid second intervention.

文摘BACKGROUND: This prospective observational study aimed to determine the infection rate of simple hand laceration(SHL), and to compare infection rates between patients who were prescribed antibiotics and those who were not.METHODS: The study was performed at two urban hospitals enrolling 125 emergency department(ED) patients with SHL. Exclusion criteria included patients with lacerations for more than 12 hours, immunocompromized patients, patients given antibiotics, and patients with gross contamination, bites or crush injuries. Wound infection was defined as clinical infection at a follow-up visit(10–14 days) or wound was treated with antibiotics. Patient satisfaction was also measured using a visual analogue scale 1–10, asking the patients about wound appearance. Demographic data and wound characteristics were compared between the infected and non-infected wounds. The infection rates were also compared between patients who received prophylactic antibiotics and those who did not. The results were presented with medians and quartiles or percentages with 95% confidence intervals(CI).RESULTS: In the 125 patients with SHL [median age: 28(18, 43); range: 1–102 years old; 36% female], 44(35%, 95% CI: 27%–44%) were given antibiotics in the ED. Wound infection was reported in 6 patients(4.8%, 95% CI: 2%–10%). Age, gender, history of diabetes and wound closure were not associated with wound infection(P>0.05). The infection rate was not significantly different between patients with or without antibiotic prophylaxis [7%(3/44), 95% CI: 2%–10% vs. 4%(3/81), 95% CI: 1%–11%, P=0.66]. Patient's satisfaction with appearance ofinfected and non-infected wounds were significantly different [7.5(6, 8) vs. 9(8, 10), P=0.01].CONCLUSION: Approximately 5% of simple hand lacerations become infected. Age, gender, diabetes, prophylactic antibiotics and closure technique do not affect the risk ofinfection.

文摘AIM:To identify the risk factors of epiphora in patients with anatomical patency after surgical repair of canalicular laceration.METHODS:This retrospective case series included 178 cases of canalicular laceration repair from 2005 to 2012.Demographic data collected from each patient included age,sex,type of injury,distance from the distal lacerated end of the canaliculus to the punctum,the severity score for the structural abnormity of the medial canthus,the duration of stent placement,and the timing of surgery.The risk factors for epiphora were evaluated using Logistic regression models.RESULTS:Among the 178 cases,45(25.3%)with lacrimal patency after irrigation had symptomatic epiphora at the final follow-up.Patients'sex,age,type of injury,duration of stent placement,timing of surgery,and concurrent trauma were not found to be significantly associated with symptomatic epiphora after surgical repair of the lacerated canaliculus(P>0.05).A distance of more than 5 mm from the distal cut end to the punctum was closely and significantly associated with symptomatic epiphora after surgical repair of the lacerated canaliculus(P<0.01).Symptomatic epiphora was significantly more frequent in patients with higher severity scores for structural abnormities of the medial canthus(P<0.01).CONCLUSION:Our results indicate that the risk factors for postoperative symptomatic epiphora include a further distance between the distal cut end and the lacrimal punctum and a higher severity score for structural abnormities of the medial canthus.These findings could be used to prognosticate postoperative symptomatic epiphora.
文摘Background: Perineal traumas particularly caused by following vaginal delivery are associated with short and long term morbidity for women. Therefore, interventions that increase the probability of intact perineum are necessary. The aim of study was to determine the effect of perineal massage with a sterile lubricant on the incidence of episiotomy and perinea laceration. Materials: This clinical trial study was performed on 145 nulliparous women who referred to Amol Emam Ali teaching center for normal delivery. They were randomly participating in interventional group (massage with lubricant) (45 cases) or control group (100 cases). In massage group when they progressed to full dilatation of the cervix, the midwife inserted two fingers inside vagina and using a sweeping motion gently stretched the perineum with lubricant 5 up to 10 minutes, in and between mother’s pushing in the second stage of labour. In control group just Ritgen Maneuver was applied. At last, we compared the rate of intact perineum, episiotomy and laceration, mean duration of the second stage of labor and Apgar score in 1 and 5 minutes between two groups. Statistical analyses were performed using t-test, Chi Square to determine potentially significant associations, and a p value less than 0.05 was considered significant. Results: The incidences of intact perineum, episiotomy and laceration were 22.2% (10), 44.4% (20), 33.3% (15) respectively in interventional group. In control group, intact perineum, episiotomy and laceration were: 20.2% (20), 49.3% (71), 28.3% (28) respectively. This difference was not statis- tically significant. Rate of first-degree laceration was 33.3% (15) in massage group, while this percent was 28.3% (28) in control group. This difference was not statistically significant. In massage and control groups, second, third and fourth-degree lacerations did not occur. Conclusion: The results showed that massage with a sterile lubricant provides no apparent and significant advantage or disadvantage in reducing perineal trauma. Therefore, the use of massage as technique for perineal control is safe based on labour criteria and woman’s preference during delivery.
文摘Objective: To determine the incidence of primary postpartum haemorrhage, identify risk/aetiological factors contributing to primary postpartum haemorrhage and review the different therapeutic approaches in the management of primary postpartum haemorrhage. Method: A retrospective case-control study of all patients with primary postpartum haemorrhage from January 1, 2001 to December 31, 2010 at Olabisi Onabanjo University Teaching Hospital, Sagamu, Nigeria. Result: In the period under review, 272 cases of primary postpartum haemorrhage were documented while there were a total of 5929 deliveries, giving an incidence of 1 in 26 (25.6%). The average blood loss in the cases reviewed was 1550 mls whilst in the controls, the average blood loss was 200 mls. There was statistical significant difference between the grandmultiparous cases and grandmultiparous controls (58.4% versus 16.5%, OR = 6.74, p < 0.05), suggesting that grandmultiparity may be an implicated factor in primary postpartum haemorrhage. In the unbooked cases, retained placenta was the major cause of primary postpartum haemorrhage constituting 109 (51.7%), whereas in booked cases, uterine atony contributed 70.5% to primary postpartum haemorrhage. Four maternal deaths were recorded giving a case fatality rate of 1.5%;all were unbooked. Conclusion: Postpartum haemorrhage ranks high in the list of causes of maternal death and the case fatality rate can be very high. Prevention is the key to reducing the incidence of PPH and its sequale, with preventive measures based upon the identification of risk factors, surveillance of women at risk and seemingly not at risk and avoidance of procedure during delivery which could potentially result in complications.
文摘BACKGROUND:This study aimed to compare the topical anesthetic lignocaine,adrenaline,and tetracaine(LAT)(4%lignocaine,1:2 000 adrenaline,1%tetracaine) with the conventional lignocaine infiltration(LI) for repair of minor lacerations,for the comfort of anesthetic administration,efficacy,adverse effects and cost.METHODS:This was a prospective randomized clinical trial.Forty Asian patients who required toilet and suture for minor lacerations in the emergency department of the Singapore General Hospital over a 4-month period.The patients were assigned randomly to 2 arms of treatment.The first was the LAT gel group who had LAT gel applied to the laceration prior to suturing.The second was the control group in whom the anesthetic administered was lignocaine infiltration(LI) via a syringe.The pain of the process of administering anesthetic and efficacy of anesthesia were scored using the visual pain scale included within.The efficacy of LAT vs.lignocaine infiltration as an anesthetic prior to the toilet and suture of minor lacerations and complications of therapy.RESULTS:Twenty patients were randomized to LAT gel and 16 to LI on an intention to treat analysis.The mean pain score by patients in the LAT gel group was 2.5(0.52 SE),and 2.5(0.58 SE)in the LI group.The pain score for pain during application of the anesthetic was 1.5(0.40) in the LAT gel group,and 3.5(0.46) in the LI group.There was no difference in complications between the LAT and LI groups.CONCLUSION:LAT gel prior to the toilet and suture of minor lacerations is proven to be as efficacious as LI in terms of patient comfort and effectiveness of anesthesia.The complications are also comparable to those treated with LI.

It also involves protection, which conforms to the minimally invasive philosophy. The proposed surgical technology can eliminate contralateral frontal hematoma under a good field of view.

文摘Background: After the Institute of Medicine(IOM) report To Err Is Human highlighted the impact of medical errors, the Agency for Healthcare Research and Quality(AHRQ) developed Patient-Safety Indicators(PSI) to improve quality by identifying potential inpatient safety problems. PSI-15 was created to study accidental punctures and lacerations(APL), but PSI-15 may underestimate APLs in populations of patients. This study compares PSI-15 with a more inclusive approach using a novel composite of secondary diagnostic and procedural codes. Methods: We used Nationwide Inpatient Sample(NIS) data(20 0 0–2012) from AHRQ’s Healthcare Cost and Utilization Project(H-CUP). We analyzed PSI-15-positive and-negative cholecystectomies. Cross tabulations identified codes that were significantly more frequent among PSI-15-positive cases; these secondary diagnostic and procedural codes were selected as candidate members of a composite marker(CM) of APL. We chose cholecystectomy patients for study because this is one of the most common general operations, and the large size of NIS allows for meaningful analysis of infrequent occurrences such as APL rates. Results: CM identified 1.13 times more APLs than did PSI-15. Patients with CM-detected APLs were significantly older and had worse mortality, comorbidities, lengths of stay, and charges than those detected with PSI-15. Further comparison of these two approaches revealed that time-series analysis for both APL markers revealed parallel trends, with inflections in 2007, and lowest APL rates in July. Conclusions: Although CM may yield more false positives, it appears more inclusive, identifying more clinically significant APLs, than PSI-15. Both measures presented similar trends over time, arguing against inflation in PSI-15 reporting. While arguably less specific, CM may increase sensitivity for detecting APL events during cholecystectomies. These results may inform the interpretation of other large population studies of APLs following abdominal operations.

文摘Results of extended and refined optical identification of 181 radio/X-ray sources in the RASS-Green Bank (RGB) catalog are presented (Brinkmann et al. 1997) which have been spectroscopically observed in the Sloan Digital Sky Survey (SDSS) DR5. The SDSS spectra of the optical counterparts are modeled in a careful and selfconsistent way by incorporating the host galaxy's starlight. Optical emission line parameters are presented, which are derived accurately and reliably, along with the radio 1.4- 5 GHz spectral indices estimated using (non-simultaneous) archival data. For 72 sources, the identifications are presented for the first time. It is confirmed that the majority of strong radio/X-ray emitters are radio-loud active galactic nuclei (AGNs), particularly blazars. Taking advantage of the high spectral quality and resolution and our refined spectral modeling, we are able to disentangle narrow line radio galaxies (NLRGs), as vaguely termed in most previous identification work, into Seyfert II galaxies and LINERs (low-ionization nuclear emission regions), based on the standard emission line diagnostics. The NLRGs in the RGB sample, mostly belonging to 'weak line radio galaxies', are found to have optical spectra consistent predominantly with LINERs, and only a small fraction with Seyfert II galaxies. A small number of LINERs have radio power as high as 10623 - 10^26 W Hz^- 1 at 5 GHz, being among the strongest radio emitting LINERs known so far. Two sources are identified with radio-loud narrow line Seyfert 1 galaxies (NLS 1 s), a class of rare objects. The presence is also confirmed of flat-spectrum radio quasars whose radio-optical-X-ray effective spectral indices are similar to those of High-energy peaked BL Lacs (HBLs), as suggested by Padovani et al., although it is still a debate as to whether this is the case for their actual spectral energy distributions.
