Medieval (arrow) weapon injuries in contemporary surgical practice: Impaled posterior thoracic wall arrowhead leading to haemo-thorax: Management protocols. Case report.

INTRODUCTION AND IMPORTANCE: Arrow injuries are rare in modern surgical practice. However, there are still case reports in tribal and guerrilla conflicts in rural settings were arrows are still used as weapons. Since the discovery of gun powder, guns and explosives have been the preferred effective assault weapons. Most surgeons in metropolitan trauma centers face scarce arrow injuries cases, mostly due to accidents or suicide attempts using the crossbow mechanism. CASE PRESENTATION: We present a case of an 18-year-old boy who sustained penetrating posterior thoracic wall arrow injury leading to haemothorax and review of the management protocols. CLINICAL DISCUSSION: Arrow injuries to the chest can span the entire spectrum of organs in the chest cavity ranging from superficial muscle to vital organs and vessels injury. Immediate death can result from injury to vital organs or vessels with late fatalities due to infection or toxins from dipped arrow heads with "poisons". Pre-operative radiological investigations such as CT scanning with angiography have proved its predictive value of intra-thoracic injuries when compared to post-operative diagnoses. CONCLUSION: Management protocols range from open thoracotomy of unstable patients to simple retrieval under thoracoscopy guide. Several management protocols set date back as early as the 16th Century still hold water to date.

Neurosurgical Education in Tanzania: The Dar es Salaam Global Neurosurgery Course.

BACKGROUND: Postgraduate neurosurgical training is essential to develop a neurosurgical workforce with the skills and knowledge to address patient needs for neurosurgical care. In Tanzania, the number of neurosurgeons and neurosurgical services offered have expanded in the past 40 years. Training opportunities within the country, however, are not sufficient to meet the needs of residents, specialists, and nurses in neurosurgery, forcing many to train outside the country incurring associated costs and burdens. We report on the Dar es Salaam Global Neurosurgery Course, which aims to provide local training to neurosurgical health care providers in Tanzania and surrounding countries. METHODS: We report the experience of the Global Neurosurgery Course held in March 2023 in Dar es Salaam, Tanzania. We describe the funding, planning, organization, and teaching methods along with participant and faculty feedback. RESULTS: The course trained 121 participants with 63 faculty-42 from Tanzania and 21 international faculty. Training methods included lectures, hands-on surgical teaching, webinars, case discussions, surgical simulation, virtual reality, and bedside teaching. Although there were challenges with equipment and Internet connectivity, participant feedback was positive, with overall improvement in knowledge reported in all topics taught during the course. CONCLUSIONS: International collaboration can be successful in delivering topic-specific training that aims to address the everyday needs of surgeons in their local setting. Suggestions for future courses include increasing training on allied topics to neurosurgery and neurosurgical subspecialty topics, reflecting the growth in neurosurgical capacity and services offered in Tanzania.

The effect of the Dar es Salaam neurosurgery training course on self-reported neurosurgical knowledge and confidence.

Introduction: The Muhimbili Orthopaedic Institute in collaboration with Weill Cornell Medicine organises an annual neurosurgery training course in Dar es Salaam, Tanzania. The course teaches theory and practical skills in neurotrauma, neurosurgery, and neurointensive care to attendees from across Tanzania and East Africa. This is the only neurosurgical course in Tanzania, where there are few neurosurgeons and limited access to neurosurgical care and equipment. Research question: To investigate the change in self-reported knowledge and confidence in neurosurgical topics amongst the 2022 course attendees. Material and methods: Course participants completed pre and post course questionnaires about their background and self-rated their knowledge and confidence in neurosurgical topics on a five point scale from one (poor) to five (excellent). Responses after the course were compared with those before the course. Results: Four hundred and seventy participants registered for the course, of whom 395(84%) practiced in Tanzania. Experience ranged from students and newly qualified professionals to nurses with more than 10 years of experience and specialist doctors. Both doctors and nurses reported improved knowledge and confidence across all neurosurgical topics following the course. Topics with lower self-ratings prior to the course showed greater improvement. These included neurovascular, neuro-oncology, and minimally invasive spine surgery topics. Suggestions for improvement were mostly related to logistics and course delivery rather than content. Discussion and conclusion: The course reached a wide range of health care professionals in the region and improved neurosurgical knowledge, which should benefit patient care in this underserved region.

Potential Spectrum of Accompanied Penetrating Abdominal Intraperitoneal Injuries with Bowel Evisceration: Surprises Awaiting the Trauma Surgeon in Resource Limited Settings.

Penetrating abdominal injuries involves violation of the peritoneal cavity and injuries to solid organs and other intraperitoneal viscera such as major blood vessels and hollow organs. Typically such injuries arise from gunshot wounds or stab wounds. With increase in crime rates and motor traffic accidents in urban areas, the trauma surgeon in civilian urban centers faces spectrum of injuries similar to his colleague in war torn areas. Potential spectrum of penetrating abdominal injuries is wide and accurate diagnosis in resource limited centers is challenging. Majority of injuries are concealed and diagnosed intraoperatively and dealt with relatively junior trauma surgeons in emergency settings in remote limited settings. Computed tomography (CT) scans and Magnetic Resonance Imaging (MRI) facilities are scarce in resource limited settings. Haemodynamic states of penetrating abdominal injuries patients presenting in emergency departments necessitate urgent surgical exploration and management with minimal room for full radiological work-up. Evisceration of bowels with unstable haemodynamic states mandate laparotomy due to wide spectrum of accompanied intraperitoneal injuries. Four cases of penetrating abdominal injuries are presented with modes of assault ranging from gunshot injuries to stab wounds with broken bottles to highlight the intra-abdominal spectrum of injuries, challenges in diagnosis and emergency managements done in a resource limited setting.

Needs of Young African Neurosurgeons and Residents: A Cross-Sectional Study.

Introduction: Africa has many untreated neurosurgical cases due to limited access to safe, affordable, and timely care. In this study, we surveyed young African neurosurgeons and trainees to identify challenges to training and practice. Methods: African trainees and residents were surveyed online by the Young Neurosurgeons Forum from April 25th to November 30th, 2018. The survey link was distributed via social media platforms and through professional society mailing lists. Univariate and bivariate data analyses were run and a P-value < 0.05 was considered to be statistically significant. Results: 112 respondents from 20 countries participated in this study. 98 (87.5%) were male, 63 (56.3%) were from sub-Saharan Africa, and 52 (46.4%) were residents. 39 (34.8%) had regular journal club sessions at their hospital, 100 (89.3%) did not have access to cadaver dissection labs, and 62 (55.4%) had never attended a WFNS-endorsed conference. 67.0% of respondents reported limited research opportunities and 58.9% reported limited education opportunities. Lack of mentorship (P = 0.023, Phi = 0.26), lack of access to journals (P = 0.002, Phi = 0.332), and limited access to conferences (P = 0.019, Phi = 0.369) were associated with the country income category. Conclusion: This survey identified barriers to education, research, and practice among African trainees and young neurosurgeons. The findings of this study should inform future initiatives aimed at reducing the barriers faced by this group.

History of African women in neurosurgery.

The number of women in the medical field has increased in Africa over the last few decades, yet the underrepresentation of women within neurosurgery has been a recurrent theme. Of all surgical disciplines, neurosurgery is among the least equitable, and the rate of increase in female surgeons lags behind other surgical disciplines such as general surgery. This historical review provides an overview of the history of women in neurosurgery and their current status on the African continent. To the authors' knowledge, this is the first article to provide such an overview.

Standard Urine Collection Bag as an Improvised Bogotá Bag as a Temporary Abdominal Closure Method in an Open Abdomen in Preventing Abdominal Compartment Syndrome.

Primary abdominal wall closure post laparotomy is not always possible. Certain surgical pathologies such as degloving anterior abdominal wall trauma injuries and peritoneal visceral volume and cavity disproportion render it nearly impossible for the attending surgeon to close the abdomen in the first initial laparotomy. In such surgical clinical scenarios leaving the abdomen open might be lifesaving. Forceful closure might lead to abdominal compartment syndrome and impair respiratory status of the patient. Open abdomen closure techniques have evolved over time from protection of abdominal viscera to complex fascia retraction prevention techniques. Silo bags, i.e., (Bogotá Bags), are relatively cheap, available materials used as a temporary abdominal closure method in limited resources settings. Despite its limitations of not preventing fascia retraction and draining of peritoneal fluid, it protects the abdominal viscera. We report a case of a 29-year-old male who developed incisional anterior abdominal wall wound dehiscence. He was scheduled for emergency explorative laparotomy. Intraoperatively, multiple attempts to reduce grossly dilated edematous bowels into the peritoneal cavity and fascia approximation into the midline were not possible. A urinary collection bag was sutured on the skin edges as a temporary abdominal closure method in prevention of abdominal compartment syndrome. He fared well postoperatively and eventually underwent abdominal incisional wound closure. In emergency abdominal surgeries done in limited surgical material resource settings were primary abdominal closure is not possible at initial laparotomy, sterile urine collection bags as alternatives to the standard Bogota bags as temporary abdominal closure materials can be safely used. These are relatively easily available and can be safely used until definite surgical intervention is achieved with relatively fewer complications.

Clinical profiles of diabetic foot ulcer patients undergoing major limb amputation at a tertiary care center in North-eastern Tanzania.

BACKGROUND: Diabetic foot ulcers complications are the major cause of non-traumatic major limb amputation. We aimed at assessing the clinical profiles of diabetic foot ulcer patients undergoing major limb amputation in the Surgical Department at Kilimanjaro Christian Medical Centre (KCMC), a tertiary care hospital in North-eastern Tanzania. METHODS: A cross-sectional hospital-based study was conducted from September 2018 through March 2019. Demographic data were obtained from structured questionnaires. Diabetic foot ulcers were graded according to the Meggitt-Wagner classification system. Hemoglobin and random blood glucose levels data were retrieved from patients' files. RESULTS: A total of 60 patients were recruited in the study. More than half (31/60; 51.67%) were amputated. Thirty-five (58.33%) were males. Fifty-nine (98.33%) had type II diabetes. Nearly two-thirds (34/60; 56.67%) had duration of diabetes for more than 5 years. The mean age was 60.06 ± 11.33 years (range 30-87). The mean haemoglobin level was 10.20 ± 2.73 g/dl and 9.84 ± 2.69 g/dl among amputees. Nearly two thirds (42/60; 70.00%) had a haemoglobin level below 12 g/dl, with more than a half (23/42; 54.76%) undergoing major limb amputation. Two thirds (23/31; 74.19%) of all patients who underwent major limb amputation had mean hemoglobin level below 12 g/dl. The mean Random Blood Glucose (MRBG) was 13.18 ± 6.17 mmol/L and 14.16 ± 6.10 mmol/L for amputees. Almost two thirds of the study population i.e., 42/60(70.00%) had poor glycemic control with random blood glucose level above 10.0 mmol/L. More than half 23/42 (54.76%) of the patients with poor glycemic control underwent some form of major limb amputation; which is nearly two thirds (23/31; 74.19%) of the total amputees. Twenty-eight (46.67%) had Meggitt-Wagner classification grade 3, of which nearly two thirds (17:60.71%) underwent major limb amputation. CONCLUSION: In this study, the cohort of patients suffering from diabetic foot ulcers treated in a tertiary care center in north-eastern Tanzania, the likelihood of amputation significantly correlated with the initial grade of the Meggit-Wagner ulcer classification. High blood glucose levels and anaemia seem to be also important risk factors but correlation did not reveal statistical significance.

Surgical Approach in Management of Posttraumatic Diaphragmatic Hernia: Thoracotomy versus Laparotomy.

Breach in diaphragmatic musculature permits abdominal viscera to herniate into the thoracic cavity. Time of presentation and associated injuries determines the surgical approach in management. This case report sets to highlight the challenges in clinical diagnosis, radiological interpretation, and surgical management approaches of posttraumatic diaphragmatic hernia. We report a case of a 43 years old male who was diagnosed with traumatic diaphragmatic hernia 6 months post blunt thoracoabdominal trauma due to motor traffic accident. He was initially diagnosed with haemothorax, drained with an underwater thoracostomy tube, and discharged. He continued to experience on and off chest pain worsening postfeeding, difficulty in breathing and abdominal pain for the next six months until his eventual diaphragmatic hernia diagnosis. He was scheduled for an elective thoracotomy. A left posterolateral thoracic over the 7th intercostal space incision was used. Intraoperatively, the stomach, left lobe of liver, part of transverse colon, small bowel, and omentum had herniated into the thoracic cavity adhering into thoracic viscera and wall. Adhesiolysis was done, and abdominal organs reduced into abdominal cavity. Rent was closed by interrupted Prolene sutures reinforced with a mesh. In patients with delayed presentation of diaphragmatic hernia post blunt thoracoabdominal injury without associated intra-abdominal visceral injury, we recommend the thoracic diaphragmatic repair approach as long-standing herniated bowels might adhere with thoracic cavity walls or viscera. In such cases, adhesiolysis and rent repair is easier through thoracotomy.

Facial Nerve Function and Quality of Resection in Large and Giant Vestibular Schwannomas Surgery Operated By Retrosigmoid Transmeatal Approach in Semi-sitting Position with Intraoperative Facial Nerve Monitoring.

INTRODUCTION: Large and giant vestibular schwannomas pose a real problem in their management. The preservation of facial nerve function may limit tumor resection despite the use of intraoperative monitoring of the facial nerve. In Algeria, vestibular schwannomas represent 5% of all intracranial tumors operated on, 80.5% of which are large or giant. METHODS: From January 2010 to December 2015, 151 large and giant vestibular schwannomas were operated in our department. Tumor diameter was between 30 and 60 mm. The most common presenting symptom was hearing loss, which was observed in 41.66% of all our patients. All patients were operated in the semi-sitting position with opening of the posterior wall of the internal auditory canal and under continuous intraoperative facial nerve function monitoring. RESULTS: Tumor resection was total in 126 patients. Anatomic preservation of the facial nerve was the reason for nontotal resection in 25 patients. The facial nerve was anatomically preserved in 149 patients. Two years after surgery, the facial nerve function was grade I-II House-Brackmann (H-B) score in 124 cases (82%), grade III-IV H-B score in 21 cases (14%), and grade V-VI H-B score in 06 cases (04%). The status and the improvement of postoperative facial nerve function depend on 4 factors: anatomic preservation of nerve, stimulation threshold, cystic form, and the presence of train activity. CONCLUSIONS: The development of anesthesia techniques and microsurgery and the systematic use of intraoperative monitoring of the facial nerve have allowed us to move from a life preservation era to another era of preservation of function.
