Titanium mesh cranioplasty for cosmetically disfiguring cranio-facial tumours in a resource limited setting.

Background: The aesthetic reconstruction of disfiguring cranio-facial defects after tumour excision can be quite challenging to the neurosurgeon with limited resources. The choice of cranioplasty implant, intraoperative technicalities and the patients' postoperative appearance are critical considerations in management. There are a number of synthetic materials available for cranioplasty, however, the customised implants are not readily available in our practice setup. They are also mostly constructed and contoured after the bony defect has been created or require sophisticated software construction pre-operatively. Methods: Eight patients with cranio-facial tumour pathologies who presented to our neurosurgical service, and had titanium mesh cranioplasty for the correction of cosmetically disfiguring cranio-facial tumours. Results: There were 6 females, and 2 male patients respectively, with an age range between 28 and 74years. The histological diagnoses were meningioma, frontal squamous cell carcinoma, fibrous dysplasia, frontal mucocoele, cemeto-ossifying fibroma, osteoma, and naso-ethmoidal squamous cell carcinoma. The patient with naso-ethmoidal squamous cell carcinoma had post-operative subgaleal empyema which was amenable to incision and drainage procedure. The patient with a frontal cemento-ossifyng fibroma had a transient immediate post-operative mechanical ptosis, which resolved completely in 3months. All of the total eight patients (100%) had satisfactory cosmetic outlook at a minimum follow up period of 1month post-operatively (Numeric Rating Scale of at least 7/10). One of the patients required a revision surgery on account of implant displacement. Conclusion: Cranioplasty is a common reconstructive neurosurgical procedure. It is important to the neurosurgeon for its neuro-protective function, and in the restoration of intra-cranial CSF dynamics. However, the cosmetic outlook appears to be more important to patients in the absence of pain and/or neurological deficits. Titanium mesh reconstruction is commonly used globally, and is becoming the preferred choice in low resource settings.

Neurocritical Care in Nigeria.

Nigeria is the most populous country in Africa with an estimated 206 million inhabitants served by less than 300 neurologists and 131 neurosurgeons. Neurological conditions account for approximately 18% of all medical emergencies. Neurocritical care challenges in Nigeria are as complex as they are in other low-to-middle-income countries (LMICs). These include high burden of neurological diseases, poor pre-hospital care, delays in transfer, lack of neurocritical care equipment, and inadequate rehabilitative capacity. Neurocritical care units in Nigeria offer mostly limited multimodal monitoring due to out-of-pocket payment, and the success of repeat radiological imaging and blood work is low. Data gathering and outcome research in neurocritical conditions can help in clinical decision-making and enhance cost-effective clinical care. The concept of allocation requires that when medical resources are scarce, they must be efficiently utilized in the most judicious way so as to achieve the greatest possible benefit. A high degree of transparency is needed with regard to the principles, values and criteria employed to facilitate such triage decisions. Proper funding will help improve availability of equipment and drugs resulting in a higher quality of care and, subsequently, improvement in mortality. There is ample evidence that neurocritical care improves overall prognosis in neurocritically-ill patients. Neurocritical care units (NCCUs) are mostly unavailable in Nigeria, often resulting in poorer prognosis for patients. What is already known: Nigeria has an unacceptably huge deficit in the overall capacity for neurocritical care. The inadequacies affect a wide range of components - facilities, quantity and quality of personnel, and the unbearably high cost, among others. What this study adds: This article attempts to condense the challenges in one piece while highlighting previously obscure ones, with the aim of providing possible solutions to the lingering challenges in neurocritical care in Nigeria and, invariably, other LMICs. How this study might affect practice, policies or research: We envisage this article will stimulate the initial steps in a multipronged and data-driven approach to bridging the gap by government and relevant healthcare administrators.

Le Nigeria est le pays le plus peuplé d'Afrique avec une population estimée à 206 millions d'habitants et à peine moins de 300 neurologues et 131 neurochirurgiens au service de cette population. Les urgences neurologiques représentent environ 18 % de toutes les urgences médicales. Les défis posés par les soins neurocritiques au Nigeria sont aussi complexes que dans d'autres pays à revenu faible ou intermédiaire (PRFI). Il s'agit notamment du lourd fardeau des maladies neurologiques, de la médiocrité des soins préhospitaliers, des retards de transfert, du manque d'équipements de soins neurocritiques et d'une capacité de réadaptation réduite. Les unités de soins neurocritiques au Nigeria disposent d'une surveillance multimodale limitée en raison du paiement direct, et le succès de la répétition de l'imagerie radiologique et des analyses sanguines est faible. La collecte de données et la recherche sur les résultats dans les conditions neurocritiques peuvent aider à la prise de décision clinique et améliorer la rentabilité des soins cliniques. Selon le concept d'allocation, lorsque les ressources médicales sont rares, elles doivent être utilisées efficacement et de la manière la plus judicieuse possible afin d'obtenir le plus grand bénéfice possible. Un degré élevé de transparence est nécessaire en ce qui concerne les principes, les valeurs et les critères utilisés pour faciliter ces décisions de triage. Un financement adéquat permettra d'améliorer la disponibilité des équipements et des médicaments, ce qui se traduira par une meilleure qualité des soins et, par la suite, par une réduction de la mortalité. Il existe de nombreuses preuves que les soins neurocritiques améliorent le pronostic général des patients en état neurocritique. Les unités de soins neurocritiques (NCCU) sont pour la plupart indisponibles au Nigeria, ce qui entraîne un pronostic plus défavorable. Ce que l'on sait déjà : Le Nigeria souffre d'un déficit inacceptable en matière de capacité globale de soins neurocritiques. Les insuffisances touchent un large éventail d'éléments - installations, quantité et qualité du personnel, et coût insupportablement élevé, entre autres. Ce que cette étude apporte : Cet article tente de condenser les défis en un seul élément tout en mettant en lumière ceux qui étaient auparavant obscurs, dans le but de fournir des solutions possibles aux défis persistants des soins neurocritiques au Nigeria et invariablement dans les pays à faible revenu intermédiaire. Comment cette étude pourrait-elle affecter la pratique, les politiques ou la recherche ? Nous pensons que cet article stimulera les premières étapes d'une approche multidimensionnelle et axée sur les données pour combler le fossé par le gouvernement et les administrateurs de soins de santé concernés.

The prevalence of IGM antibodies to Zika virus in pregnant women in Northern Nigeria.

INTRODUCTION: Zika virus (ZIKV) infection during pregnancy can result in severe outcomes for both the pregnant woman and the developing fetus. The objective of this study was to investigate the prevalence of Zika virus infection among pregnant women who sought healthcare services at Ahmadu Bello University Teaching Hospital. MATERIALS AND METHODS: Serum samples were collected and analyzed using Enzyme Linked Immunoassay and RT-qPCR methods, while a structured questionnaire was used to gather relevant information about the participants. RESULTS: The results showed that 53 out of the 180 pregnant women tested positive for Anti-Zika IgM antibodies, which represents a 29.4% prevalence rate. Subsequent RT-qPCR analysis found that only 6 out of the 53 positive samples contained Zika virus RNA. Fever and headache were the most commonly reported symptoms related to the infection. CONCLUSION: These findings indicate a potential outbreak of Zika fever in Northern Nigeria emphasizing the importance for pregnant women to take precautions to avoid getting infected.

Nigerian resident doctors' work schedule: A national study.

Background and Aim: The deleterious effects of Resident Doctors' (RDs') long duty hours are well documented. Driven by concerns over the physician's well-being and patient safety, the RDs' duty hours in many developed countries have been capped. However, in Nigeria and many African countries, there are no official regulations on work hours of RDs. This study evaluated the work schedule of Nigerian RDs and its impact on their wellbeing and patient safety. Subjects and Methods: A national survey of 1105 Nigerian RDs from all specialties in 59 training institutions was conducted. With an electronic questionnaire designed using Google Forms, data on the work activities of RDs were obtained and analyzed using the IBM SPSS software version 24. The associations were compared using Chi-squared test with the level of significance set at < 0.05. Results: The mean weekly duty hours (h) of the RDs was 106.5 ± 50.4. Surgical residents worked significantly longer hours than non-surgical residents (122.7 ± 34.2 h vs 100.0 ± 43.9 h; P < 0.001). The modal on-call frequency was two weekday on-calls per week (474, 42.9%) and two weekend on-calls per month (495, 44.8%), with the majority of RDs working continuously for up to 24 hours during weekday on-calls (854, 77.3%) and 48-72 hours during weekend on-calls (568, 51.4%), sleeping for an average of only four hours during these on-calls. The majority of RDs had post-call clinical responsibilities (975, 88.2%) and desired official regulation of duty hours (1,031, 93.3%). Conclusion: The duty hours of Nigerian RDs are currently long and unregulated. There is an urgent need to regulate them for patient and physician safety.

Tramadol-Induced Acute Seizures: A Report of Three Cases.

There is a rise in substance abuse in Nigeria and prescription drugs, particularly opioid analgesics, which are increasingly becoming a target of abuse. Abuse of the opiod tramadol has the potential to precipitate seizures. We present 3 cases of tramadol-induced seizures presenting at Obafemi Awolowo University Teaching Hospitals Complex, Ile-Ife. The three patients were men, aged 22-40 years and abused other drugs including alcohol, cannabis and Rohypnol. This report illustrates the fact that tramadol abuse may be associated with acute seizures and it is reasonable to consider drug/opiod-induced seizure in every case of unexplained first episode of seizure in a young adult.

L'abus de substances psychoactives est en hausse au Nigeria et les médicaments sur ordonnance, en particulier les analgésiques opioïdes, qui deviennent de plus en plus une cible d'abus. L'abus de l'opioïde tramadol a le potentiel de précipiter des crises d'épilepsie. Nous présentons 3 cas de crises d'épilepsie induites par le tramadol se présentant à Complexe hospitalier universitaire Obafemi Awolowo, Ile-Ife. Les trois patients étaient des hommes, âgés de 22 à 40 ans et abusaient d'autres drogues dont l'alcool, le cannabis et le Rohypnol. Ce rapport illustre le fait que l'abus de tramadol peut être associé à des crises aiguës. associé à des crises d'épilepsie aiguës et il est raisonnable d'envisager une crise induite par le médicament ou par une période dans tous les cas de premier épisode de crise inexpliqué chez un jeune adulte.

Aplasia Cutis Congenita: A Case Report.

Aplasia cutis congenita (ACC) is a rare developmental disorder that is not fully understood. It often occurs in isolation but can also be syndromic. Usually, there is an absence of the epidermis and dermis. It may be limited to the skin alone but may involve deeper structures. Research has identified a heterogeneous predisposition including genetic factors. Among patients with ACC, scalp involvement is common, however large scalp defects with the involvement of the skull is not common. We present a preterm neonate with a large scalp ACC with a wide skull defect.

L'aplasie cutanée congénitale (ACC) est un mal du développement rare qui n'est pas entièrement compris. Elle survient souvent de manière isolée mais peut également être syndromique. Habituellement, il y a une absence d'épiderme et de derme. Elle peut être limitée à la peau seule mais peut impliquer des structures plus profondes. La recherche a identifié une prédisposition hétérogène incluant des facteurs génétiques. Chez les patients atteints d'ACC, l'atteinte du cuir chevelu est fréquente, mais de grandes anomalies du cuir chevelu avec atteinte du crâne ne sont pas courantes. Nous présentons un nouveau-né prématuré avec un grand CCA du cuir chevelu avec un large défaut du crâne.

Skin Photosensitivity is Associated with 25-Hydroxyvitamin D and BMD but not Fractures Independent of Melanin Density in Older Caucasian Adults.

Whether skin photosensitivity modulates sun exposure behaviours, consequent vitamin D status and skeletal health outcomes independently of constitutive pigmentation have not been systematically investigated. 1072 community-dwelling adults aged 50-80 years had skin photosensitivity quantified by questionnaire and melanin density by spectrophotometry. Bone mineral density (BMD), falls risk and 25-hydroxyvitamin D (25OHD) were measured using DXA, short form physiological profile assessment and radioimmunoassay, respectively. Sun exposure and symptomatic fractures were assessed by questionnaire. Participants were followed up at 2.5 (n = 879), 5 (n = 767) and 10 (n = 571) years. Higher resistance to sunburn and greater ability to tan were associated with reduced sun protection behaviours (RR 0.87, p < 0.001 & RR 0.88, p < 0.001), higher lifetime discretionary sun exposure in summer (RR 1.05, p = 0.001 & RR 1.07, p = 0.001) and winter (RR 1.07, p = 0.001 & RR 1.08, p = 0.02) and fewer lifetime sunburns (RR 0.86, p < 0.001 & RR 0.91, p = 0.001). Higher resistance to sunburn was associated with lower total body (ß = - 0.006, p = 0.047) and femoral neck (ß = - 0.006, p = 0.038) BMD, but paradoxically, fewer prevalent fractures (RR 0.94, p = 0.042). Greater ability to tan was associated with higher 25OHD (ß = 1.43, p = 0.04), lumbar spine (ß = 0.014, p = 0.046) and total body (ß = 0.013, p = 0.006) BMD, but not fracture or falls risk. These associations were independent of constitutive melanin density. Cutaneous photosensitivity was associated with sun exposure behaviours, cutaneous sequelae and, consequently, 25OHD and BMD in older Caucasian adults independent of constitutive melanin density. There was no consistent association with fracture outcomes, suggesting environmental factors are at least as important.

Prevalence and Impact of Work-Related Musculoskeletal Disorders on Job Performance of Call Center Operators in Nigeria.

BACKGROUND: Work-related musculoskeletal disorders (WMSDs) have been documented among various occupational groups in Nigeria. However, there is limited data on the prevalence of WMSDs among call center operators (CCOs). OBJECTIVE: To determine the prevalence of WMSDs among CCOs in Nigeria and to explore the extent to which these discomforts impact the daily work activities of the respondents. METHODS: 374 respondents who were randomly selected from 4 telecommunication companies in Lagos State, Nigeria, participated in this study. They were asked to complete a pre-tested questionnaire designed to capture the prevalence, impact and associated risk factors of WMSDs among CCOs. RESULTS: 42% and 65.2% of respondents experienced at least one WMSDs in the past 7 days, and 12 months, respectively. Women and CCOs who received calls with hand-held phones rather than headsets reported more discomforts during both 7 days and 12 months periods. Neck, shoulder, upper back, and lower back were the most affected areas during past 7 days and 12 months. Discomforts in the neck, low back, and knees prevented most of the respondents from performing their daily work. CONCLUSION: WMSDs have a serious impact on the daily job activities of the CCOs in Nigeria.

Innovative interprofessional geriatric education for medical and nursing students: focus on transitions in care.

BACKGROUND: Interprofessional education (IPE) is crucial in fostering effective collaboration and optimal team-based patient care, all of which improve patient care and outcomes. Appropriate interprofessional communication is especially important in geriatrics where patients are vulnerable to adverse effects across the care continuum. Transitions in geriatric care are complex, involving several disciplines and requiring careful coordination. As part of the University of Virginia's initiative on IPE, we developed and implemented an interprofessional geriatric education workshop for nursing and medical students with a focus on transitions in care. METHODS: A total of 254 students (144 medical students, 107 nursing students and 3 unknown) participated in a 90-min interactive, case-based workshop. Nursing and medical faculty facilitated the monthly workshops with small groups of medical and nursing students over 1 year. Self-perceived competencies in IPE skills and attitudes toward interprofessional teamwork were measured through post-workshop surveys. Data were analyzed using descriptive and nonparametric statistics, excluding the three unknown students. RESULTS: Over 90% of students were better able to describe the necessary interprofessional communication needed to develop a patient-centered care plan in transitioning patients between clinical sites. Four out of five students reported an enhanced appreciation of interprofessional teamwork. They were also able to identify legal, financial and social implications in transitions of care (75%). Nursing students consistently rated the workshop more highly than medical students across most domains (P < 0.05). CONCLUSIONS: Students improved and demonstrated their knowledge of interprofessional communication and teamwork skills required in transitions of geriatric care. Introducing these concepts in medical and nursing training may help in fostering effective interprofessional communication and collaboration.

Age-related differences in renal function at onset of renal replacement therapy in chronic kidney disease stage 5 patients.

BACKGROUND: Guidelines for initiating renal replacement therapy (RRT) are based on renal function and not age, so renal function at onset of RRT is expected to be similar across age groups. AIM: To evaluate renal function at initiation of RRT across age groups. DESIGN: Observational cross-sectional study. METHODS: We extracted data for all incident chronic kidney disease (CKD) stage 5 patients (n = 322 064) commenced on chronic dialysis (haemodialysis and peritoneal) and renal transplant in the US from 1995 to 1999 from the US Renal Data Systems (USRDS). Subjects (n = 662) with incomplete data were excluded. The reminder (n = 321 402) were classified into five age groups: 0-19 years; 20-44 years; 45-64 years; 65-74 years; >/=75 years. Mean values of serum creatinine (Cr, mg/dl), creatinine clearance (CrCl, ml/min), body weight (kg) and body mass index (BMI, kg/m(2)) at onset of RRT were computed. Mean daily urinary creatinine excretion per kg body weight (CrCl x Cr/0.07/weight) was also calculated. RESULTS: Progressively lower serum creatinine levels were found in adult patients with increasing age (10.70, 8.56, 7.38 and 6.88 mg/dl in those aged 20-44 years, 45-64 years, 65-74 years, >/=75 years, respectively). CrCl was also lower in the same groups (14.76, 13.38, 11.63 and 11.60 ml/min, respectively). DISCUSSION: Older patients have a greater reduction in renal function than younger patients at onset of RRT, suggesting a delay in initiation of therapy.
