In order to improve performance, and the quality of care, and to identify common pathologies in the surgical department, we undertook a retrospective study on surgical activities from January 2009 to December 2010. At the end of this study, out of 474 men and 187 women (equal sex ratio 2.53);we were able to determine the frequency of surgical pathologies. Farmers, housewives and pupils/students were the most represented with 25.9% respectively;20% and 13.3%. The most frequently observed pathologies were wall hernia (44.8%), prostate adenoma (12%) and acute appendicitis (10.5%). The average length of hospitalization was 3.43 days. Infectious complications affected 25 patients (3.8% of cases) and a death rate of 0.45% (i.e. 3 patients). The average cost of care was 53,500 FCFA. Indeed, the reality of surgical practice in health centers was not the same because of the level of skills of practicing surgeons.展开更多

The overall objective was to assess the quality of management of acute malnutrition in children aged 0 - 24 months at the Boulbinet health center. Methodology: This was a prospective descriptive study lasting six (06) months from May 5 to October 5, 2018. The study included all children aged 0 to 24 months. Results: Acute malnutrition in children aged 0 - 24 months accounted for 2.11% of cases. The sex ratio was 1.41 in favor of males. The mean age of our patients was 5 months 7 days, with extremes of 1 month and 6 months. The majority came from Ra toma (40.24%). Exclusive breastfeeding was most common (54.02%). The main clinical signs were: pallor 49.42%, diarrhea 46.67, oral lesions37.96%. SAM represented 89.66% and MAM 10.34%. Most associated pathologies: anemia 49.42% and oral candidiasis 37.93%. In terms of outcome, we recorded 56.32% cures, 20.69% deaths, 18.39% dropouts and 4.60% cures. Conclusion: Improving the quality of care for malnourished children aged 0 - 24 months requires raising awareness among mothers and the general public of the consequences of malnutrition.展开更多

Objectives: To study the hospital frequency of lower extremity arterial disease and identify associated factors in diabetic patients at the Libreville University Hospital Center (CHUL). Materials and Methods: This was a cross-sectional study conducted from July 1, 2023, to January 31, 2024, in the endocrinology department of the CHUL. All patients with type 2 diabetes over the age of 18 admitted to this department, regardless of the reason for hospitalization, who provided informed consent, were included. Socio-demographic data and cardiovascular risk factors were recorded. Personal and family cardiovascular history and functional symptoms were investigated. The physical examination included measuring blood pressure, heart rate, and the ankle-brachial index in all patients. Results: A total of 219 patients were included, of whom 75 had lower extremity arterial disease, representing a prevalence of 34.24%. It was compensated in 28 cases (37.33%) and decompensated in 39 patients (52%). In eight cases (10.67%), there was critical chronic ischemia. Cardiovascular risk factors associated with diabetes were physical inactivity (89.5%), hypertension (55.25%), overweight (49.77%), obesity (22.84%), and smoking (10.04%). In multivariate analysis, only hypertension (OR = 2.09;95% CI: 1.05 - 4.17;p = 0.035) and LDL cholesterol (OR = 2.75;95% CI: 1.10 - 6.85;p = 0.03) were significantly associated with lower extremity arterial disease in diabetics at the University Hospital of Libreville. Conclusion: Lower extremity arterial disease is common in diabetic patients at the University Hospital of Libreville. It is often asymptomatic, thus requiring systematic screening.[-rId11-]展开更多

Purpose: To describe the specific aspects of squamous cell carcinoma of the conjunctiva and to determine the therapeutic modalities. Materials and Methods: Descriptive cross-sectional retrospective study carried out at the University Hospital Center of Bouake over a period of 9 years (From January 2015 to December 2023). We identified all malignant oculo-adnexal and orbital tumors whose histopathological diagnosis was confirmed;monitoring the sorting of squamous cell carcinomas of the conjunctiva among these cancers and studying the different parameters linked to them. Results: The average age of patients is 44.3 years. Male predominance with a sex ratio of 1.12. HIV was the majority ATCD with 64.7%. The main reason for consultation was exophthalmos (36.11%). The average consultation time was 10 months 13 days. Invasive differentiated conjunctival squamous cell carcinoma was predominant at 55.56%. Enucleation was the most performed surgical method. Conclusion: Squamous cell carcinoma of the conjunctiva is a malignant ocular tumor of the elderly whose frequency increases in young adults infected with HIV-AIDS. Invasive differentiated forms are increasingly encountered, limiting treatment to mutilating surgery.展开更多

The aim of this study is to analyze the epidemiological, clinical, therapeutic and evolving aspects of hemorrhoidal disease at the stage of surgical treatment at the University Hospital Center of Brazzaville. Patients and Methods: We conducted a retrospective and descriptive study carried out from January 2020 to December 2021, a 24 months period, in the Digestive surgery department of the University Hospital Center of Brazzaville. It concerned patients who underwent a surgical procedure for hemorrhoidal disease. Results: 21 cases were collected, representing a hospital frequency of 2.3%, with a sex ratio of 4.3 in favor of men. The average age of patients was 42.2 ± 11.9 years. The symptoms were mainly proctalgia, mass sensation and rectal bleeding. We recorded five cases (19.1%) of hemorrhoidal thrombosis and 16 cases (80.9%) of hemorrhoidal prolapse including 12 cases requiring manual integration (Goligher grade III) and four irreducible permanent cases (Goligher grade IV). The Grade III prolapse was associated with a polyp in one patient and with posterior anal fissure in another patient. Out of the 21 patients, 14 underwent a tripedicular hemorrhoidectomy according to Milligan and Morgan. Two patients underwent mono- and bipedicular hemorrhoidectomy with resection of associated lesions and five patients underwent emergency thrombectomy. The outcome was favorable for all our patients. The average length of hospital stay was 1.5 ± 2.1 days. Conclusion: In the event of failure of medical and instrumental treatment, the hemorrhoidal cure according to Milligan and Morgan is the surgical treatment of reference for hemorrhoidal disease at the University Hospital Center of Brazzaville.展开更多

Among the causes of maternal and perinatal death, high blood pressure associated with pregnancy occupies a significant part. It represents 5% of direct maternal deaths. Objective: to study the maternal and perinatal prognosis of high blood pressure during pregnancy in the Tenenkou reference health center in Mali. Methodology: This was a descriptive, analytical and retrospective cross-sectional study over a period of twelve months from January 1, 2021 to December 31, 2021 and involving 144 cases of high blood pressure associated with pregnancy. Results: We obtained a frequency of 11.75%. The majority of patients 70.9% were aged between 20 - 35 years. The important risk factor found was young age. During our study, 46.5% of patients had performed at least one CPN and only 13.9% performed 04 CPN. Pre-eclampsia was the most common type of high blood pressure during pregnancy, i.e. 61.1%. Eclampsia and retroplacental hematoma were the most common maternal complications, respectively 27.8% and 11.1%. The most common fetal complications were premature births and fetal distress with 20.9% and 17.4% respectively. Conclusion: Hypertension associated with pregnancy still remains a major cause of maternal-fetal morbidity and mortality in our context where diagnosis is often late. The main clinical form was preeclampsia. Eclampsia and retroplacental hematoma were the most frequent maternal complications. Fetal complications were mainly prematurity and fetal distress.展开更多

We aimed to evaluate the attitudes and practices of students, interns, and residents about LP, and to assess their feelings about how this procedure is taught. Materials and Methods: We conducted a cross-sectional study of 160 participants, using an anonymous questionnaire, to evaluate the attitudes and practices of students, interns and residents in the pediatrics department concerning lumbar puncture. Results: Half of the participants had never performed LP, usually because of the risk involved or lack of confidence, while 20% had performed it more than 4 times. None of the participants had learned to perform the procedure through simulation sessions, while (42%) had learned it under the supervision of a senior physician and had not been able to perform it successfully the first time. Most participants inform the patient about the procedure before performing it. Only 44% of participants acknowledged that LP can be performed under local anesthetic. The sitting position (60%) was by far the most commonly used. Most LPs were performed for diagnostic purposes. Most participants stated that the pediatric ward and the pediatric emergency department are among the departments that perform LP most frequently, and that they would be interested in taking part in simulated lumbar puncture sessions in children in the future. Conclusion: The results of our study show that LP is perceived by students as a risky procedure that is difficult to perform. Teachers should reconsider how this technical procedure is taught, by integrating simulation on mannequins into student training.展开更多

The majority of fibroids are asymptomatic and do not require any intervention or other exploratory measures. However, in some cases fibroids are symptomatic, their treatment should aim to improve symptoms and quality of life. Objectives: Describe the epidemiological-clinical aspects of uterine fibroids in the gynecology and obstetrics department of the reference health center of commune VI of the Bamako district. Methodology: This was a retrospective descriptive study carried out over a period of one year. It concerns all patients seen in consultation in the gynecology and obstetrics department of the reference health center of commune VI. Results: during the study period, the uterine fibroid frequency was 1.80%. During this same period, fibroids represented 5.59% of gyneco-obstetric pathologies operated on in the department. The 30 - 45 year old age group was the most represented with a frequency of 75.63%. The average age was 36.87 years ± 6.2 years with extremes of 25 and 63 years. Married women were the most represented 97.48%. The vast majority of our patients 95.8% were not postmenopausal. The multigravidas were the most represented, i.e. 37.50% with a large part of the pauciparous 41.29%. In our patients, 96.64% had a clinical symptom on their fibroid with the main reason for consultation being the sensation of a pelvic mass in 97.48%. We recorded three cases of infertility as associated factors. Ultrasound was performed in all patients. The location of the myxomatous nuclei was subserosal in the majority in 42.86% and with multiple nodules in 84.85% of cases. The main indication for myomectomy was the failure of medical treatment in 86.49% of cases. Surgical treatment was mainly a myomectomy 93.30%, a hysterectomy was indicated in 6.70%. No cases of death were recorded. Conclusion: Uterine fibroid is a gynecological pathology that exists in our department;its frequency is estimated at 5.59%. For better management of fibroids, it is necessary to have a good knowledge of the factors favoring the occurrence of uterine fibroids, their growth and the symptoms to prevent the appearance of it or even at best to operate. This prevention must be a concern for public health because fibromatous pathology is frequent, costly and hampers quality of life.展开更多

CAD is a shared burden disease and the leading cause of death in developed and developing countries. We aimed to assess the angiographic patterns of coronary arteries in patients with DM in a developing country (Yemen) as the first study. Methods: This study is a cross-sectional, prospective, observational study that includes a total of 250 patients who were admitted for elective diagnostic coronary angiography. Results: 96 (38.4%) patients were diabetics;68% were male;mean age was 57 ± 11 years. The incidence of three-vessel disease was 31.2% of patients. Considering the severity of lumen occlusion, (11.2%) of patients had non-significant lesions, (37.6%) of patients had significant lesions, and (32%) had total occlusive lesions. Lesions were of LAD in 76%, RCA in 60%, and LCX in 52% of the population. Among diabetics, two and 3-vessel diseases (33.3% vs. 20.8% & 50% vs. 19.5%, P = 0.001), left main lesion (10.4% vs. 2.6%, P = 0.012), significant stenosis (41.7% vs. 35.1%, P = 0.032), total occlusion of coronary arteries (43.8% vs. 19.5%, P = 0.032) and type C lesion (66.7% vs. 35.1%, P = 0.010) were more frequent than non-DM patients. Conclusion: The burden of significant and severe coronary lesions is more common among DM, which may be the major cause of morbidity and mortality of DM in developing countries.展开更多

It is characterized by an oedematous, multifocal and bilateral degeneration of the nasosinus mucosa, which originates in the lateral masses of the ethmoid, where it causes the formation of smooth, gelatinous, translucent and pyriform polyp lesions. The objective of this study was to review epidemiological, clinical, paraclinical data and evaluate the results of endoscopic surgical treatment. Patients and Methods: This is a retrospective study on 60 patients followed at the ENT department of the Fann National University Hospital Center, from January 2010 to December 2015. All patients with sinonasal polyposis were included in the study. Results: The average age of our patients was 38 years and the sex ratio (M/F) was 0.8. In the patients’ histories, we found 18% asthma and 10% Widal’s disease. The average consultation time was 8.5 years. All patients had consulted for nasal obstruction;rhinorrhea was bilateral and found in 67.7% of cases, with olfactory disorders accounting for 50%. The CT scan performed in 58% of cases made it possible to specify the extent of the lesions;the involvement of the ethmoidal sinus was constant and extended to the other sinuses except in 2 cases. All patients had received medical treatment with local corticosteroids. Endoscopic surgical treatment was initiated in 43% of cases after failure of corticosteroid-based medical treatment. The evolution under treatment marked by the reappearance of symptoms that increased each month. At one month postoperatively, all clinical symptomatology had improved with the exception of olfactory disorders, which persisted in 3 patients. At 12 months we noted 12 cases of reappearance of nasal obstruction. Conclusion: SNP is a disease of little known etiology. The diagnosis is almost always clinical. Endoscopic surgery remains a recourse to medical treatment. For good local control, patients should be more respectful of good compliance with corticosteroid therapy.展开更多

Patients and method: This is a retrospective study, covering the period from January to December 2015, carried out in the ophthalmology unit of the CSREF in Kati. Results: The sample consisted of 568 patients, or 6.82% of ophthalmological consultations. Children aged 0 to 14 years accounted for 154 (27.11%) of the trauma cases. Bruises constitute the main circumstance (58.1%) of eye trauma, followed by domestic accidents (15.6%). Closed globe ocular trauma was the main type of trauma (61.6%), followed by ocular adnexal trauma (30.1%) and open globe trauma (8.3%) in which the penetrating wound was the lesion, the least common (2.6%) but the most serious. Medical treatment was the most used therapeutic modality in 82.4% of cases, followed by surgery with 17.6% of cases. The evolution of the lesions after treatment was favorable in 85.6% of cases and unfavorable in 14.4% of cases. Complications were observed in 5.8% of cases and sequelae in 8.6% of cases. Conclusion: Ocular trauma constitutes an important reason for ophthalmological consultation at the CSREF of Kati. The severity of some of these lesions requires frequent recourse to surgery. The complexity of the treatment should encourage us to favor preventive measures.展开更多

文摘Development of the telencephalon relies upon several signaling centers-localized cellular populations that supply secreted factors to pattern the cortical neuroepithelium.One such signaling center is the cortical hem,which arises during embryonic development at the telencephalic dorsal midline,adjacent to the choroid plexus and hippocampal primordium(Figure 1A).While the cortical hem has also been described in reptiles and birds,most of our knowledge about the developmental roles of the cortical hem is derived from the analysis in mice.The cortical hem produces several types of secreted molecules,including wingless-related integration site(Wnt)and bone morphogenetic(Bmp)proteins.The cortical hem is particularly important for the development of the hippocampus,which is involved in learning and memory,and the neocortex,which is the most complex brain region that mediates multiple types of behavior and higher cognitive functions(Mangale et al.,2008;Dal-Valle-Anton and Borrell,2022).
文摘The objectives of this work were to evaluate the surgical activities carried out in the general surgery department of the Reference Health Center of Commune I of Bamako, to describe the sociodemographic characteristics of the operated patients, to determine the main pathologies encountered and to evaluate qualitatively the result of the treatment. In order to improve performance, and the quality of care, and to identify common pathologies in the surgical department, we undertook a retrospective study on surgical activities from January 2009 to December 2010. At the end of this study, out of 474 men and 187 women (equal sex ratio 2.53);we were able to determine the frequency of surgical pathologies. Farmers, housewives and pupils/students were the most represented with 25.9% respectively;20% and 13.3%. The most frequently observed pathologies were wall hernia (44.8%), prostate adenoma (12%) and acute appendicitis (10.5%). The average length of hospitalization was 3.43 days. Infectious complications affected 25 patients (3.8% of cases) and a death rate of 0.45% (i.e. 3 patients). The average cost of care was 53,500 FCFA. Indeed, the reality of surgical practice in health centers was not the same because of the level of skills of practicing surgeons.
文摘Introduction: Malnutrition is a pathological state resulting from the relative deficiency or excess of one or more essential nutrients, whether manifested clinically or detected only by biochemical, anthropometric or physiological analyses. The overall objective was to assess the quality of management of acute malnutrition in children aged 0 - 24 months at the Boulbinet health center. Methodology: This was a prospective descriptive study lasting six (06) months from May 5 to October 5, 2018. The study included all children aged 0 to 24 months. Results: Acute malnutrition in children aged 0 - 24 months accounted for 2.11% of cases. The sex ratio was 1.41 in favor of males. The mean age of our patients was 5 months 7 days, with extremes of 1 month and 6 months. The majority came from Ra toma (40.24%). Exclusive breastfeeding was most common (54.02%). The main clinical signs were: pallor 49.42%, diarrhea 46.67, oral lesions37.96%. SAM represented 89.66% and MAM 10.34%. Most associated pathologies: anemia 49.42% and oral candidiasis 37.93%. In terms of outcome, we recorded 56.32% cures, 20.69% deaths, 18.39% dropouts and 4.60% cures. Conclusion: Improving the quality of care for malnourished children aged 0 - 24 months requires raising awareness among mothers and the general public of the consequences of malnutrition.

文摘Tuning the coordination atoms of central metal is an effective means to improve the electrocatalytic activity of atomic catalysts.Herein,iridium(Ir) is proposed to be asymmetrically anchored by sp-N and pyridinic N of hydrogen-substituted graphdiyne(HsGDY),and coordinated with OH as an Ir atomic catalyst(Ir_(1)-N-HsGDY).The electron structures,especially the d-band center of Ir atom,are optimized by these specific coordination atoms.Thus,the as-synthesized Ir_(1)-N-HsGDY exhibits excellent electrocatalytic performances for oxygen reduction and hydrogen evolution reactions in both acidic and alkaline media.Benefiting from the unique structure of HsGDY,IrN_(2)(OH)_(3) has been developed and demonstrated to act as the active site in these electrochemical reactions.All those indicate the fresh role of the sp-N in graphdiyne in producing a new anchor way and contributing to promote the electrocatalytic activity,showing a new strategy to design novel electrochemical catalysts.

文摘The safety and effectiveness of magnetic resonance-guided focused ultrasound thalamotomy has been broadly established and validated for the treatment of essential tremor.In 2018,the first magnetic resonance-guided focused ultrasound system in Chinese mainland was installed at the First Medical Center of the PLA General Hospital.This prospective,single center,open-label,single-arm study was part of a worldwide prospective multicenter clinical trial(ClinicalTrials.gov Identifier:NCT03253991)conducted to confirm the safety and efficacy of magnetic resonance-guided focused ultrasound for treating essential tremor in the local population.From 2019 to 2020,10 patients with medication refractory essential tremor were recruited into this open-label,single arm study.The treatment efficacy was determined using the Clinical Rating Scale for Tremor.Safety was evaluated according to the incidence and severity of adverse events.All of the subjects underwent a unilateral thalamotomy targeting the ventral intermediate nucleus.At the baseline assessment,the estimated marginal mean of the Clinical Rating Scale for Tremor total score was 58.3±3.6,and this improved after treatment to 23.1±6.4 at a 12-month follow-up assessment.A total of 50 adverse events were recorded,and 2 were defined as serious.The most common intraoperative adverse events were nausea and headache.The most frequent postoperative adverse events were paresthesia and equilibrium disorder.Most of the adverse events were mild and usually disappeared within a few days.Our findings suggest that magnetic resonance-guided focused ultrasound for the treatment of essential tremor is effective,with a good safety profile,for patients in Chinese mainland.
文摘The journey to implement cancer genomic medicine(CGM)in oncology practice began in the 1980s,which is considered the dawn of genetic and genomic cancer research.At the time,a variety of activating oncogenic alterations and their functional significance were unveiled in cancer cells,which led to the development of molecular targeted therapies in the 2000s and beyond.Although CGM is still a relatively new discipline and it is difficult to predict to what extent CGM will benefit the diverse pool of cancer patients,the National Cancer Center(NCC)of Japan has already contributed considerably to CGM advancement for the conquest of cancer.Looking back at these past achievements of the NCC,we predict that the future of CGM will involve the following:1)A biobank of paired cancerous and non-cancerous tissues and cells from various cancer types and stages will be developed.The quantity and quality of these samples will be compatible with omics analyses.All biobank samples will be linked to longitudinal clinical information.2)New technologies,such as whole-genome sequencing and artificial intelligence,will be introduced and new bioresources for functional and pharmacologic analyses(e.g.,a patient-derived xenograft library)will be systematically deployed.3)Fast and bidirectional translational research(bench-to-bedside and bedside-to-bench)performed by basic researchers and clinical investigators,preferably working alongside each other at the same institution,will be implemented;4)Close collaborations between academia,industry,regulatory bodies,and funding agencies will be established.5)There will be an investment in the other branch of CGM,personalized preventive medicine,based on the individual's genetic predisposition to cancer.

文摘Precision medicine is a growing field worldwide.Despite its potential benefit to many patients,several major obstacles must be overcome before precision medicine can be more widely used in clinical practice.The main obstacles are associated with the quality of samples used for genomic analysis。
文摘Introduction: Lower extremity arterial disease in diabetic patients has distinct characteristics. Objectives: To study the hospital frequency of lower extremity arterial disease and identify associated factors in diabetic patients at the Libreville University Hospital Center (CHUL). Materials and Methods: This was a cross-sectional study conducted from July 1, 2023, to January 31, 2024, in the endocrinology department of the CHUL. All patients with type 2 diabetes over the age of 18 admitted to this department, regardless of the reason for hospitalization, who provided informed consent, were included. Socio-demographic data and cardiovascular risk factors were recorded. Personal and family cardiovascular history and functional symptoms were investigated. The physical examination included measuring blood pressure, heart rate, and the ankle-brachial index in all patients. Results: A total of 219 patients were included, of whom 75 had lower extremity arterial disease, representing a prevalence of 34.24%. It was compensated in 28 cases (37.33%) and decompensated in 39 patients (52%). In eight cases (10.67%), there was critical chronic ischemia. Cardiovascular risk factors associated with diabetes were physical inactivity (89.5%), hypertension (55.25%), overweight (49.77%), obesity (22.84%), and smoking (10.04%). In multivariate analysis, only hypertension (OR = 2.09;95% CI: 1.05 - 4.17;p = 0.035) and LDL cholesterol (OR = 2.75;95% CI: 1.10 - 6.85;p = 0.03) were significantly associated with lower extremity arterial disease in diabetics at the University Hospital of Libreville. Conclusion: Lower extremity arterial disease is common in diabetic patients at the University Hospital of Libreville. It is often asymptomatic, thus requiring systematic screening.[-rId11-]

文摘AIM:To evaluate the efficacy and safety of perfluoro-n-octane(PFO)for ophthalmic surgery versus F-Octane as an intraoperative tamponade in pars plana vitrectomy(PPV)in management of retinal detachment.METHODS:This multicenter,prospective,randomized,double-masked,parallel-controlled,non-inferiority trial was conducted in three ophthalmology clinical centers in China.Patients with retinal detachment,who were eligible for PPV were consecutively enrolled.Participants were assigned to PFO for ophthalmic surgery or F-Octane for intraocular tamponade in a 1:1 ratio.Best-corrected visual acuity(BCVA),intraocular pressure(IOP)measurement,and dilated fundus examination were performed preoperatively and at 1,7±1,28±3d postoperatively.The primary outcome was complete retinal reattachment rate at postoperative day one.The non-inferiority margin was set at 9.8%.The secondary outcomes included intraoperative retinal reattachment rate,and mean changes in IOP and BCVA from baseline to 1,7±1,28±3d postoperatively,respectively.Safety analyses were presented for all randomly assigned participates in this study.RESULTS:Totally 124 eligible patients completed the study between Mar.14,2016 and Jun.7,2017.Sixty of them were randomly assigned to the PFO for ophthalmic surgery group,and 64 were assigned to the F-Octane group.Baseline characteristics were comparable between the two groups.Both groups achieved 100%retinal reattachment at postoperative day one(difference 0,95%CI:-6.21%to 5.75%,P=1).The pre-defined noninferiority criterion was met.No significant difference was observed in intraoperative retinal reattachment rate(difference 1.77%,P=0.61),mean changes in IOP(difference 0.36,-0.09,2.22 mm Hg at 1,7±1,28±3d postoperatively,with all P>0.05)and BCVA(difference 0.04,-0.02,0.06 logMAR at 1,7±1,28±3d postoperatively,all P>0.05)between the two groups.No apparent adverse events related to the utilization of PFO were reported.CONCLUSION:In patients with retinal detachment undergoing PPV,PFO for ophthalmic surgery is non-inferior to F-Octane as an intraocular tamponade,and both are safe and well-tolerated.
文摘AIM:To provide a comprehensive and more representative national data on the disease,especially on treatment options and outcomes,and to determine access of retinoblastoma patients from Luzon,Visayas and Mindanao to eye care,and determine if access is associated with delay in consultation,staging and outcomes.METHODS:Cohort study of retinoblastoma patients seen in eleven institutions located in the three major areas of the Philippines namely Luzon,Vizayas and Mindanao from 2010-2020.RESULTS:Totally 636 patients,involving 821 eyes,were included.Majority(57%)were from Luzon and were seen in institutions in Luzon(72%).Annually,58±10 new cases were seen with 71%having unilateral disease.Median delay of consultation remained long at 9(3,17)mo,longest in patients with unilateral disease(P<0.02)and those from the Visayas(P<0.003).Based on the International Retinoblastoma Staging System,only 35%of patients had Stage 1 while 47%already had extraocular disease.Enucleation was the most common treatment received by 484 patients while intravenous chemotherapy was received by 469.There were 250(39%)patients alive,195(31%)dead,85(13%)abandoned,17(3%)refused and 89(14%)with no data.CONCLUSION:This study presents the largest cohort of retinoblastoma patients in the Philippines in terms of patients’and participating institutions’number and geographical location and type of institution(private and public).It also presents more comprehensive data on the treatments used and outcomes(survival,globe salvage,and vision retention rates).Delay in consultation was still long among patients leading to advanced disease stage and lower survival rate.Despite increasing capacity to diagnose and manage retinoblastoma in the country,the delay of consultation remains long primarily due to accessibility issues to eye care institutions especially in the Visayas and financial concerns.The delay was still significant that overall survival rate remain low.
文摘Introduction: Squamous cell carcinoma of the conjunctiva is one of the most common malignancies in the elderly. Purpose: To describe the specific aspects of squamous cell carcinoma of the conjunctiva and to determine the therapeutic modalities. Materials and Methods: Descriptive cross-sectional retrospective study carried out at the University Hospital Center of Bouake over a period of 9 years (From January 2015 to December 2023). We identified all malignant oculo-adnexal and orbital tumors whose histopathological diagnosis was confirmed;monitoring the sorting of squamous cell carcinomas of the conjunctiva among these cancers and studying the different parameters linked to them. Results: The average age of patients is 44.3 years. Male predominance with a sex ratio of 1.12. HIV was the majority ATCD with 64.7%. The main reason for consultation was exophthalmos (36.11%). The average consultation time was 10 months 13 days. Invasive differentiated conjunctival squamous cell carcinoma was predominant at 55.56%. Enucleation was the most performed surgical method. Conclusion: Squamous cell carcinoma of the conjunctiva is a malignant ocular tumor of the elderly whose frequency increases in young adults infected with HIV-AIDS. Invasive differentiated forms are increasingly encountered, limiting treatment to mutilating surgery.
文摘Introduction: Hemorrhoidal disease is a common pathology and its surgical treatment is based, among other things, on pedicular resection after failure of medical and instrumental treatment. The aim of this study is to analyze the epidemiological, clinical, therapeutic and evolving aspects of hemorrhoidal disease at the stage of surgical treatment at the University Hospital Center of Brazzaville. Patients and Methods: We conducted a retrospective and descriptive study carried out from January 2020 to December 2021, a 24 months period, in the Digestive surgery department of the University Hospital Center of Brazzaville. It concerned patients who underwent a surgical procedure for hemorrhoidal disease. Results: 21 cases were collected, representing a hospital frequency of 2.3%, with a sex ratio of 4.3 in favor of men. The average age of patients was 42.2 ± 11.9 years. The symptoms were mainly proctalgia, mass sensation and rectal bleeding. We recorded five cases (19.1%) of hemorrhoidal thrombosis and 16 cases (80.9%) of hemorrhoidal prolapse including 12 cases requiring manual integration (Goligher grade III) and four irreducible permanent cases (Goligher grade IV). The Grade III prolapse was associated with a polyp in one patient and with posterior anal fissure in another patient. Out of the 21 patients, 14 underwent a tripedicular hemorrhoidectomy according to Milligan and Morgan. Two patients underwent mono- and bipedicular hemorrhoidectomy with resection of associated lesions and five patients underwent emergency thrombectomy. The outcome was favorable for all our patients. The average length of hospital stay was 1.5 ± 2.1 days. Conclusion: In the event of failure of medical and instrumental treatment, the hemorrhoidal cure according to Milligan and Morgan is the surgical treatment of reference for hemorrhoidal disease at the University Hospital Center of Brazzaville.
文摘Introduction: Maternal mortality constitutes a public health problem and its rate is an indicator of a country’s development. Among the causes of maternal and perinatal death, high blood pressure associated with pregnancy occupies a significant part. It represents 5% of direct maternal deaths. Objective: to study the maternal and perinatal prognosis of high blood pressure during pregnancy in the Tenenkou reference health center in Mali. Methodology: This was a descriptive, analytical and retrospective cross-sectional study over a period of twelve months from January 1, 2021 to December 31, 2021 and involving 144 cases of high blood pressure associated with pregnancy. Results: We obtained a frequency of 11.75%. The majority of patients 70.9% were aged between 20 - 35 years. The important risk factor found was young age. During our study, 46.5% of patients had performed at least one CPN and only 13.9% performed 04 CPN. Pre-eclampsia was the most common type of high blood pressure during pregnancy, i.e. 61.1%. Eclampsia and retroplacental hematoma were the most common maternal complications, respectively 27.8% and 11.1%. The most common fetal complications were premature births and fetal distress with 20.9% and 17.4% respectively. Conclusion: Hypertension associated with pregnancy still remains a major cause of maternal-fetal morbidity and mortality in our context where diagnosis is often late. The main clinical form was preeclampsia. Eclampsia and retroplacental hematoma were the most frequent maternal complications. Fetal complications were mainly prematurity and fetal distress.
文摘Introduction: Even though lumbar puncture (LP) represents an important tool in the diagnosis of certain neurological diseases, this procedure is little practiced by our students. We aimed to evaluate the attitudes and practices of students, interns, and residents about LP, and to assess their feelings about how this procedure is taught. Materials and Methods: We conducted a cross-sectional study of 160 participants, using an anonymous questionnaire, to evaluate the attitudes and practices of students, interns and residents in the pediatrics department concerning lumbar puncture. Results: Half of the participants had never performed LP, usually because of the risk involved or lack of confidence, while 20% had performed it more than 4 times. None of the participants had learned to perform the procedure through simulation sessions, while (42%) had learned it under the supervision of a senior physician and had not been able to perform it successfully the first time. Most participants inform the patient about the procedure before performing it. Only 44% of participants acknowledged that LP can be performed under local anesthetic. The sitting position (60%) was by far the most commonly used. Most LPs were performed for diagnostic purposes. Most participants stated that the pediatric ward and the pediatric emergency department are among the departments that perform LP most frequently, and that they would be interested in taking part in simulated lumbar puncture sessions in children in the future. Conclusion: The results of our study show that LP is perceived by students as a risky procedure that is difficult to perform. Teachers should reconsider how this technical procedure is taught, by integrating simulation on mannequins into student training.
文摘Introduction: Uterine fibroid is a mixed mesenchymal tumor, developing from smooth muscle cells of the myometrium, separated by connective tissue. The majority of fibroids are asymptomatic and do not require any intervention or other exploratory measures. However, in some cases fibroids are symptomatic, their treatment should aim to improve symptoms and quality of life. Objectives: Describe the epidemiological-clinical aspects of uterine fibroids in the gynecology and obstetrics department of the reference health center of commune VI of the Bamako district. Methodology: This was a retrospective descriptive study carried out over a period of one year. It concerns all patients seen in consultation in the gynecology and obstetrics department of the reference health center of commune VI. Results: during the study period, the uterine fibroid frequency was 1.80%. During this same period, fibroids represented 5.59% of gyneco-obstetric pathologies operated on in the department. The 30 - 45 year old age group was the most represented with a frequency of 75.63%. The average age was 36.87 years ± 6.2 years with extremes of 25 and 63 years. Married women were the most represented 97.48%. The vast majority of our patients 95.8% were not postmenopausal. The multigravidas were the most represented, i.e. 37.50% with a large part of the pauciparous 41.29%. In our patients, 96.64% had a clinical symptom on their fibroid with the main reason for consultation being the sensation of a pelvic mass in 97.48%. We recorded three cases of infertility as associated factors. Ultrasound was performed in all patients. The location of the myxomatous nuclei was subserosal in the majority in 42.86% and with multiple nodules in 84.85% of cases. The main indication for myomectomy was the failure of medical treatment in 86.49% of cases. Surgical treatment was mainly a myomectomy 93.30%, a hysterectomy was indicated in 6.70%. No cases of death were recorded. Conclusion: Uterine fibroid is a gynecological pathology that exists in our department;its frequency is estimated at 5.59%. For better management of fibroids, it is necessary to have a good knowledge of the factors favoring the occurrence of uterine fibroids, their growth and the symptoms to prevent the appearance of it or even at best to operate. This prevention must be a concern for public health because fibromatous pathology is frequent, costly and hampers quality of life.
文摘Background: Diabetes mellitus (DM) is independently associated with an increased risk of cardiovascular mortality and morbidity, including coronary artery disease (CAD). CAD is a shared burden disease and the leading cause of death in developed and developing countries. We aimed to assess the angiographic patterns of coronary arteries in patients with DM in a developing country (Yemen) as the first study. Methods: This study is a cross-sectional, prospective, observational study that includes a total of 250 patients who were admitted for elective diagnostic coronary angiography. Results: 96 (38.4%) patients were diabetics;68% were male;mean age was 57 ± 11 years. The incidence of three-vessel disease was 31.2% of patients. Considering the severity of lumen occlusion, (11.2%) of patients had non-significant lesions, (37.6%) of patients had significant lesions, and (32%) had total occlusive lesions. Lesions were of LAD in 76%, RCA in 60%, and LCX in 52% of the population. Among diabetics, two and 3-vessel diseases (33.3% vs. 20.8% & 50% vs. 19.5%, P = 0.001), left main lesion (10.4% vs. 2.6%, P = 0.012), significant stenosis (41.7% vs. 35.1%, P = 0.032), total occlusion of coronary arteries (43.8% vs. 19.5%, P = 0.032) and type C lesion (66.7% vs. 35.1%, P = 0.010) were more frequent than non-DM patients. Conclusion: The burden of significant and severe coronary lesions is more common among DM, which may be the major cause of morbidity and mortality of DM in developing countries.

文摘BACKGROUND:Unsustained return of spontaneous circulation(ROSC)is a critical barrier to survival in cardiac arrest patients.This study examined whether end-tidal carbon dioxide(ETCO_(2))and pulse oximetry photoplethysmogram(POP)parameters can be used to identify unsustained ROSC.METHODS:We conducted a multicenter observational prospective cohort study of consecutive patients with cardiac arrest from 2013 to 2014.Patients’general information,ETCO_(2),and POP parameters were collected and statistically analyzed.RESULTS:The included 105 ROSC episodes(from 80 cardiac arrest patients)comprised 51 sustained ROSC episodes and 54 unsustained ROSC episodes.The 24-hour survival rate was significantly higher in the sustained ROSC group than in the unsustained ROSC group(29.2%vs.9.4%,P<0.05).The logistic regression analysis showed that the difference between after and before ROSC in ETCO_(2)(ΔETCO_(2))and the difference between after and before ROCS in area under the curve of POP(ΔAUCp)were independently associated with sustained ROSC(odds ratio[OR]=0.931,95%confi dence interval[95%CI]0.881-0.984,P=0.011 and OR=0.998,95%CI 0.997-0.999,P<0.001).The area under the receiver operating characteristic curve ofΔETCO_(2),ΔAUCp,and the combination of both to predict unsustained ROSC were 0.752(95%CI 0.660-0.844),0.883(95%CI 0.818-0.948),and 0.902(95%CI 0.842-0.962),respectively.CONCLUSION:Patients with unsustained ROSC have a poor prognosis.The combination ofΔETCO_(2) andΔAUCp showed signifi cant predictive value for unsustained ROSC.
文摘BACKGROUND Screening for iron deficiency anemia(IDA)is important in managing pediatric patients with inflammatory bowel disease(IBD).Concerns related to adverse reactions may contribute to a reluctance to prescribe intravenous(IV)iron to treat IDA in this population.AIM To track the efficacy and safety of IV iron therapy in treating IDA in pediatric IBD patients admitted to our center.METHODS A longitudinal observational cohort study was performed on 236 consecutive pediatric patients admitted to our tertiary IBD care center between September 2017 and December 2019.92 patients met study criteria for IDA,of which 57 received IV iron,17 received oral iron,and 18 were discharged prior to receiving iron therapy.RESULTS Patients treated with IV iron during their hospitalization experienced a significant increase of 1.9(±0.2)g/dL in mean(±SE)hemoglobin(Hb)concentration by the first ambulatory follow-up,compared to patients who received oral iron 0.8(±0.3)g/dL or no iron 0.8(±0.3)g/dL(P=0.03).One out of 57(1.8%)patients that received IV iron therapy experienced an adverse reaction.CONCLUSION Our findings demonstrate that treatment with IV iron therapy is safe and efficacious in improving Hb and iron levels in pediatric patients with IDA and active IBD.
文摘Introduction: Sinonasal polyposis (SNP) is a chronic inflammatory disease of the mucosa of the nasal cavities and facial sinuses. It is characterized by an oedematous, multifocal and bilateral degeneration of the nasosinus mucosa, which originates in the lateral masses of the ethmoid, where it causes the formation of smooth, gelatinous, translucent and pyriform polyp lesions. The objective of this study was to review epidemiological, clinical, paraclinical data and evaluate the results of endoscopic surgical treatment. Patients and Methods: This is a retrospective study on 60 patients followed at the ENT department of the Fann National University Hospital Center, from January 2010 to December 2015. All patients with sinonasal polyposis were included in the study. Results: The average age of our patients was 38 years and the sex ratio (M/F) was 0.8. In the patients’ histories, we found 18% asthma and 10% Widal’s disease. The average consultation time was 8.5 years. All patients had consulted for nasal obstruction;rhinorrhea was bilateral and found in 67.7% of cases, with olfactory disorders accounting for 50%. The CT scan performed in 58% of cases made it possible to specify the extent of the lesions;the involvement of the ethmoidal sinus was constant and extended to the other sinuses except in 2 cases. All patients had received medical treatment with local corticosteroids. Endoscopic surgical treatment was initiated in 43% of cases after failure of corticosteroid-based medical treatment. The evolution under treatment marked by the reappearance of symptoms that increased each month. At one month postoperatively, all clinical symptomatology had improved with the exception of olfactory disorders, which persisted in 3 patients. At 12 months we noted 12 cases of reappearance of nasal obstruction. Conclusion: SNP is a disease of little known etiology. The diagnosis is almost always clinical. Endoscopic surgery remains a recourse to medical treatment. For good local control, patients should be more respectful of good compliance with corticosteroid therapy.
文摘Introduction: The authors wanted to study the prevalence of ocular trauma in the ophthalmology unit of the CSREF of Kati. Patients and method: This is a retrospective study, covering the period from January to December 2015, carried out in the ophthalmology unit of the CSREF in Kati. Results: The sample consisted of 568 patients, or 6.82% of ophthalmological consultations. Children aged 0 to 14 years accounted for 154 (27.11%) of the trauma cases. Bruises constitute the main circumstance (58.1%) of eye trauma, followed by domestic accidents (15.6%). Closed globe ocular trauma was the main type of trauma (61.6%), followed by ocular adnexal trauma (30.1%) and open globe trauma (8.3%) in which the penetrating wound was the lesion, the least common (2.6%) but the most serious. Medical treatment was the most used therapeutic modality in 82.4% of cases, followed by surgery with 17.6% of cases. The evolution of the lesions after treatment was favorable in 85.6% of cases and unfavorable in 14.4% of cases. Complications were observed in 5.8% of cases and sequelae in 8.6% of cases. Conclusion: Ocular trauma constitutes an important reason for ophthalmological consultation at the CSREF of Kati. The severity of some of these lesions requires frequent recourse to surgery. The complexity of the treatment should encourage us to favor preventive measures.
