BACKGROUND Hallux valgus(HV)is a common foot deformity that manifests with increasing age,especially in women.The associated foot pain causes impaired gait and decreases quality of life.Moderate and severe HV is a deformity that is charac-terized by the involvement of lesser rays and requires complex surgical treatment.In this study,we attempted to develop a procedure for this condition.AIM To analyse the treatment results of patients who underwent simultaneous surgical correction of all parts of a static forefoot deformity.METHODS We conducted a prospective clinical trial between 2016 and 2021 in which 30 feet with moderate or severe HV associated with Tailor’s bunion and metatarsalgia were surgically treated via a new method involving surgical correction of all associated problems.This method included a modified Lapidus procedure,M2M3 tarsometatarsal arthrodesis,intermetatarsal fusion of the M4 and M5 bases,and the use of an original external fixation apparatus to enhance correction power.Preoperative,postoperative,and final follow-up radiographic data and American Orthopaedic Foot and Ankle Society(AOFAS)scores were compared,and P values<0.05 were considered to indicate statistical significance.RESULTS The study included 28 females(93.3%)and 2 males feet(6.7%),20(66.7%)of whom had a moderate degree of HV and 10(33.3%)of whom had severe deformity.M2 and M3 metatarsalgia was observed in 21 feet,and 9 feet experienced pain only at M2.The mean follow-up duration was 11 months.All patients had good correction of the HV angle[preoperative median,36.5 degrees,interquartile range(IQR):30-45;postoperative median,10 degrees,IQR:8.8-10;follow-up median,11.5 degrees,IQR:10-14;P<0.01].At follow-up,metatarsalgia was resolved in most patients(30 vs 5).There was a clinically negligible decrease in the corrected angles at the final follow-up,and the overall AOFAS score was significantly better(median,65 points,IQR:53.8-70;vs 80 points,IQR:75-85;P<0.01).CONCLUSION The developed method showed good sustainability of correction power in a small sample of patients at the one-year follow-up.Randomized clinical trials with larger samples,as well as long-term outcome assessments,are needed in the future. 展开更多

BACKGROUND After approval for clinical use in 2017,early investigations of ultra-high-field abdominal magnetic resonance imaging(MRI)have demonstrated its feasibility as well as diagnostic capabilities in neuroimaging.However,there are no to few systematic reviews covering the entirety of its neurosurgical applications as well as the trends in the literature with regard to the aforementioned application.AIM To assess the impact of 7-Tesla MRI(7T MRI)on neurosurgery,focusing on its applications in diagnosis,treatment planning,and postoperative assessment,and to systematically analyze and identify patterns and trends in the existing literature related to the utilization of 7T MRI in neurosurgical contexts.METHODS A systematic search of PubMed was conducted for studies published between January 1,2017,and December 31,2023,using MeSH terms related to 7T MRI and neurosurgery.The inclusion criteria were:Studies involving patients of all ages,meta-analyses,systematic reviews,and original research.The exclusion criteria were:Pre-prints,studies with insufficient data(e.g.,case reports and letters),non-English publications,and studies involving animal subjects.Data synthesis involved standardized extraction forms,and a narrative synthesis was performed.RESULTS We identified 219 records from PubMed within our defined period,with no duplicates or exclusions before screening.After screening,125 articles were excluded for not meeting inclusion criteria,leaving 94 reports.Of these,2 were irrelevant to neurosurgery and 7 were animal studies,resulting in 85 studies included in our systematic review.Data were categorized by neurosurgical procedures and diseases treated using 7T MRI.We also analyzed publications by country and the number of 7T MRI facilities per country was also presented.Experi-mental studies were classified into comparison and non-comparison studies based on whether 7T MRI was compared to lower field strengths.CONCLUSION 7T MRI holds great potential in improving the characterization and understanding of various neurological and psychiatric conditions that may be neurosurgically treated.These include epilepsy,pituitary adenoma,Parkinson's disease,cerebrovascular diseases,trigeminal neuralgia,traumatic head injury,multiple sclerosis,glioma,and psychiatric disorders.Superiority of 7T MRI over lower field strengths was demonstrated in terms of image quality,lesion detection,and tissue characterization.Findings suggest the need for accelerated global distribution of 7T magnetic resonance systems and increased training for radiologists to ensure safe and effective integration into routine clinical practice. 展开更多

Background and Aims: Pulse pressure variation (PPV) is a reliable and predictive dynamic parameter presently being utilized for fluid responsiveness. In the operating room, fluid administration based on PPV monitoring helps the physician in deciding whether to volume resuscitate or use interventions in patients undergoing surgery. Propofol is an intravenous induction agent which lowers blood pressure. There are multiple causes such as depression in cardiac output, and peripheral vasodilatation for hypotension. We undertook this study to observe the utility of PPV as a guide to fluid therapy after propofol induction. Primary outcome of our study was to monitor PPV as a marker of fluid responsiveness for the hypotension caused by propofol induction. Secondary outcome included the correlation of PPV with other hemodynamic parameters like heart rate (HR), systolic blood pressure (SBP), and diastolic blood pressure (DBP);after induction with propofol at regular interval of time. Methods: A total number of 90 patients were recruited. Either of the radial artery was then cannulated under local anaesthesia with 20G VygonLeadercath arterial cannula and invasive monitoring transduced. A baseline recording of heart rate (HR), systolic blood pressure (SBP), diastolic blood pressure (DBP) and PPV was then recorded. Patients were then induced with predetermined doses of propofol (2 mg/kg) and recordings of HR, SBP, DBP, and PPV were taken at 5, 10 and 15 minutes. Results: Intraoperatively, PPV was significantly higher at 5 minutes and significantly lower at 15 minutes after induction. It was observed that there were no statistically significant correlations between PPV and SBP or DBP. PPV was strongly and directly associated with HR. Conclusion: We were able to establish that PPV predicts fluid responsiveness in hypotension caused by propofol induction;and can be used to administer fluid therapy in managing such hypotension. However, PPV was not directly correlated with hypotension subsequent to propofol administration. 展开更多

BACKGROUND Superimposed high-frequency jet ventilation(SHFJV)is suitable for respiratory motion reduction and essential for effective lung tumor ablation.Fluid filling of the target lung wing one-lung flooding(OLF)is necessary for therapeutic ultrasound applications.However,whether unilateral SHFJV allows adequate hemodynamics and gas exchange is unclear.AIM To compared SHFJV with pressure-controlled ventilation(PCV)during OLF by assessing hemodynamics and gas exchange in different animal positions.METHODS SHFJV or PCV was used alternatingly to ventilate the non-flooded lungs of the 12 anesthetized pigs during OLF.The animal positions were changed from left lateral position to supine position(SP)to right lateral position(RLP)every 30 min.In each position,ventilation was maintained for 15 min in both modalities.Hemodynamic variables and arterial blood gas levels were repeatedly measured.RESULTS Unilateral SHFJV led to lower carbon dioxide removal than PCV without abnormally elevated carbon dioxide levels.SHFJV slightly decreased oxygenation in SP and RLP compared with PCV;the lowest values of PaO_(2) and PaO_(2)/FiO_(2) ratio were found in SP[13.0;interquartile range(IQR):12.6-5.6 and 32.5(IQR:31.5-38.9)kPa].Conversely,during SHFJV,the shunt fraction was higher in all animal positions(highest in the RLP:0.30).CONCLUSION In porcine model,unilateral SHFJV may provide adequate ventilation in different animal positions during OLF.Lower oxygenation and CO_(2) removal rates compared to PCV did not lead to hypoxia or hypercapnia.SHFJV can be safely used for lung tumor ablation to minimize ventilation-induced lung motion. 展开更多

Background: Despite the advances in anesthetics and non-pharmacological techniques, the prevalence of postoperative nausea and vomiting in all patients remains high. It is one of the most common distressing symptoms that cause dissatisfaction among patients after anesthesia and surgery. A sub-hypnotic dose of propofol has been shown to reduce morphine-induced postoperative nausea, vomiting, and pruritus. This review article will provide sufficient knowledge on the role of propofol in minimizing opioid-induced postoperative nausea, vomiting, and pruritus by providing detailed information on propofol antiemetic and antipruritic effects, as well as discussions based on empirically available data. Method: We conducted a narrative review of the literature published between 1990 and 2023 from a range of databases;PubMed, BioMed Central, Biosis Previews, Nature, International Pharmaceutical Abstracts, Springer-Link, and Elsevier. Discussion and Conclusion: The literatures reviewed in this study have demonstrated that propofol may have diverse therapeutic effects including antiemetic and antipruritic. The antiemetic effect of propofol may be an effective therapeutic approach for the prevention of postoperative nausea and vomiting. The literature also demonstrated that the use of propofol for sedation during surgery may as well ameliorates opioids induced postoperative pruritus, which may be beneficial to surgical patients. Also, it was demonstrated that prophylactic use of propofol may be an effective way of preventing nausea and vomiting and pruritus during opioid use. 展开更多

Intra-abdominal hypertension(IAH)and abdominal compartment syndrome(ACS)play a pivotal role in the pathophysiology of severe acute pancreatitis(SAP)and contribute to new-onset and persistent organ failure.The optimal management of ACS involves a multi-disciplinary approach,from its early recognition to measures aiming at an urgent reduction of intra-abdominal pressure(IAP).A targeted literature search from January 1,2000,to November 30,2022,revealed 20 studies and data was analyzed on the type and country of the study,patient demographics,IAP,type and timing of surgical procedure performed,post-operative wound management,and outcomes of patients with ACS.There was no randomized controlled trial published on the topic.Decom-pressive laparotomy is effective in rapidly reducing IAP(standardized mean difference=2.68,95%confidence interval:1.19-1.47,P<0.001;4 studies).The morbidity and complications of an open abdomen after decompressive laparotomy should be weighed against the inadequately treated but,potentially lethal ACS.Disease-specific patient selection and the role of less-invasive decompressive measures,like subcutaneous linea alba fasciotomy or component separation techniques,is lacking in the 2013 consensus management guidelines by the Abdominal Compartment Society on IAH and ACS.This narrative review focuses on the current evidence regarding surgical decompression techniques for managing ACS in patients with SAP.However,there is a lack of high-quality evidence on patient selection,timing,and modality of surgical decompression.Large prospective trials are needed to identify triggers and effective and safe surgical decompression methods in SAP patients with ACS. 展开更多

The intensive care unit provides critically ill patients with the necessary monitoring, care and supports to optimize their organ/system functions. Parturients are often at risk of sudden deteriorations or exacerbation of chronic illnesses from direct or indirect causes and would often require admissions into the intensive care or high dependency unit. This study is aimed at looking at the trends of maternal admissions in 365 days at the intensive care unit of a tertiary teaching hospital in Southern part of Nigeria, a country that contributes significantly to the global proportion of maternal morbidity and mortality. METHODS. The study adopted a retrospective approach. All critically ill parturients admitted and requiring organ support or close monitoring in the ICU had their files and ICU documents reviewed. The review was held from January-December 2018. RESULTS. Thirty-nine (39) parturients with a mean age (years) of 33 ± 1.3 were admitted, representing 2.9% of annual deliveries. All admissions were postnatal and came predominantly from the unbooked labour ward (51%) and the time lag from maternal deteriorations to presentation to the ICU was 72 ± 10 hours. The main indications for admissions were due to postpartum haemorrhage (33.3%), complications of hypertensive disorders of pregnancy (30.9%) and sepsis (25.6%). Nineteen (48.7%) patients died from obstetric haemorrhage, complications of hypertensive disorders of pregnancy, sepsis and pulmonary embolism. CONCLUSION. The trend of maternal admissions at this specific time frame reflects the burden of maternal critical care in our environment. It highlights the need to holistically tackle the known scourge with improved care. 展开更多

Background: Blood loss during caesarean section (C/S) may lead to postpartum haemorrhage, and is one of the direct causes of maternal mortality and morbidity globally. Tranexamic acid is recommended in the treatment of postpartum haemorrhage (PPH) if oxytocin and other utertonics are ineffective in controlling PPH. In this centre it is not used prophylactically to reduce blood during caesarean section. Aim: To assess the effect of prophylactic intravenous tranexamic acid on blood loss during and after elective C/S at the University of Port Harcourt Teaching Hospital (UPTH). Methods: This was a prospective, single-blind, randomized, placebo-controlled interventional study conducted at the Obstetric theatre of UPTH from July 2020 to March 2021. Eligible women were randomized into two groups;seventy-two women received intravenous tranexamic acid while seventy-one women received a placebo. Socio-demographic data and the result of the study were collected through a proforma. Data collected was analyzed using Statistical Package for Social Sciences (SPSS) Version 22.0. The results were expressed in tables and charts as frequencies, percentages and mean. Chi-square test, Fisher’s exact, and T-test were used to determine the relationship between variables. P-value ≤ 0.05 was considered statistically significant. Results: The findings showed that tranexamic acid significantly reduced mean blood loss during and after C/S (p-value post-surgery was significantly lower in the tranexamic acid group (624.88 ± 200.76 ml) in comparison to the placebo group (864.24 ± 229.09 ml), p-value = 0.001. The mean post-C/S packed cell volume (PCV) was significantly higher among the tranexamic acid group (30.68% ± 2.80%) in comparison to the placebo group (28.07% ± 3.27%), t = 5.131, p-value = 0.0001. The maternal side effects were nausea and vomiting, 9 (12.5%) and 1 (1.4%) participants respectively. Conclusion: Tranexamic acid significantly reduced blood loss during and after elective C/S. Maternal side effects were less with tranexamic acid use. 展开更多

Eclampsia is a common complication of hypertensive disorders of pregnancy and in the puerperium with the attendant risk to both the mother and baby. Although it is a multi-systemic disorder, its manifestation that affects the brain and resulting in altered sensorium demands brain imaging to define the possible brain lesions and the implications for critical care management and outcome. We evaluated the CT brain lesions in the patients with eclampsia who were admitted in the intensive care unit, University of Port Harcourt, Port Harcourt Nigeria. Objective: To analyse the CT brain images of eclamptic parturients and the outcome following their admission in the intensive care unit. Methods: We undertook this observational study after obtaining ethical exemption from the University of Portharcourt Teaching Hospital ethical review board, and commenced the review between March 2021 to February 2023. We included all parturients that were admitted into the intensive care unit of the University of Portharcourt Teaching Hospital, a nine-bedded open intensive care unit with the clinical diagnosis of eclampsia. Every admitted parturient was required to obtain a brain computed tomography (CT) by local protocol. The brain CT images were retrieved for review from the parturients’ relatives, radiology department and the ICU. Parturients included were aged ≥ 18 years. The radiological reports of these brain images which were also reviewed by a neurosurgeon in case of any need for secondary opinion were subjected to statistical analysis. Result: Thirty-one parturients were admitted with eclampsia with a mean age of 30 years ± 5.29. Sixteen (16) parturients died representing 52%. Only twenty-four (24) CT brain images were retrieved for review (77%). The following brain lesions were identified from the brain CT and they comprised the following: intracerebral haemorrhage, including extensions into the ventricles 7 (29.17%), cerebral oedema 12 (50%), subdural hematoma 1 (4.17%) and normal imaging 4 (16.66%). The subdural haematoma was promptly evacuated with a good outcome. Conclusion: Neuro imaging comprising computed tomography and magnetic resonance imaging of the brain are basic ancillary investigations for patients with eclampsia presenting with neurologic deficits and low GCS. Early presentation and access to brain CT could influence outcome as it was demonstrated in the prompt intervention in the patient with subdural haematoma which was evacuated with a satisfactory outcome. 展开更多

It can clinically mimic an ST-segment elevation myocardial infarction. We present a case of a 63 year old female, who was diagnosed with takotsubo cardiomyopathy in the immediate postoperative period, following microwave ablation for a metastatic liver lesion. Despite takotsubo cardiomyopathy only accounting for a small percentage of acute coronary syndrome presentations, it is still an important differential to be considered when dealing with acute cardiac events, as the subsequent management is different as compared to the other more often encountered forms of acute cardiac events. . 展开更多
