Telemedicine and Neurology: A Survey of Neurology Patients in a Nigerian Tertiary Hospital.

Background Telemedicine has been recognized as a viable solution for addressing the shortage of medical professionals in developing countries such as Nigeria. Tele-neurology has the potential to provide remote consultations and care for patients with neurological conditions, thereby reducing the burden of travel and improving access to medical care. Despite its growing popularity, there is a lack of research on patient's views on this mode of care delivery in Nigeria. This study was conducted to investigate patient's perspectives on the use of tele-neurology in Nigeria. Methodology A descriptive cross-sectional study was conducted among 398 neurology patients at Olabisi Onabanjo University Teaching Hospital, Sagamu, Ogun State, Nigeria. The data obtained were analyzed using descriptive statistics and a chi-square test using p < 0.05. Results Only 3% of our respondents had previously used telemedicine, with 78.1% of the respondents open to using telemedicine as a means of consultation. The disadvantages of telemedicine noted include limitations in assessing neurological status (94.7%), difficulty in explaining health conditions (84.4%), and lack of technical support (14.6%). The majority of respondents (96.5%) believed telemedicine will help in saving time. There was a statistically significant association between propensity to use telemedicine and time spent in the hospital (0.045) and time off work (<0.001). The propensity to use telemedicine was statistically significant to the use of email (0.001) and type of email address (0.001). Conclusion The findings suggested that there is a need for healthcare providers and policymakers to invest in developing telemedicine to improve access to care.

Survey of Teleneurology Use by Neurologists in a Low-Middle Income Country.

Background Teleneurology has been in existence for decades, and the COVID-19 pandemic has escalated its widespread usage. Neurological conditions are a leading cause of death globally, with sub-Saharan Africa bearing the bulk of the burden. Nigeria has few trained neurologists with the few available concentrated in an urban region. The adoption of teleneurology will help close this treatment gap. Despite evidence of its advantage, the adoption and state of teleneurology in Nigeria are very low. This study aims to determine the state and perception of teleneurology in the care of neurological patients in Nigeria and identify challenges to its wide usage. Methods The primary research method was a descriptive cross-sectional survey among 48 neurologists in Nigeria across the six geo-political zones of the country. Descriptive statistics such as frequency and percentage were used to summarize and present the results. Results A total of 48 neurologists participated, of which 46 (95.8%) specialized in general neurology. Videoconferencing is the most preferred means of telemedicine (24, 50%), followed by phone calls (16, 33.3%) and short messages (6, 12.5%). Three-quarters of the respondents are concerned about legal actions from telemedicine use. The majority (34, 70.9%) are not familiar with telemedicine tools, and 40 (83.3%) indicate low telemedicine seminar attendance. More than 90% (46) of neurologists believe that it is a viable approach and can save time and money. Barriers to telemedicine included the lack of incentive to use the technology (38, 79.2%), poor Internet connectivity (36, 75%), and the lack of exposure to telemedicine (36, 75%). Conclusions It is important to overcome the existing barrier to teleneurology in order to fully harness its potential in addressing the shortage of health professionals in Nigeria as most neurologists are open to using it.

Common mental health problems and associated factors among medical students of University of Ibadan, Nigeria.

BACKGROUND: The burden of mental health problems among medical students is on the increase especially when compared with their counterparts in other disciplines. This has counterproductive impact on the society. Understanding the prevalence and predictors of common mental health problems can inform early intervention to curb this menace. AIMS: This study was conducted to determine the prevalence, pattern and correlates of common mental health problems (anxiety and depression) amongst medical students of the University of Ibadan, Nigeria. METHODOLOGY: A descriptive cross-sectional survey was conducted among 690 pre-clinical and clinical medical students of the University of Ibadan. Data were analyzed using descriptive statistics, Chi-square test and binary logistic regression at p < 0.05. RESULTS: The prevalence of anxiety and depression were 26.5% and 10.1%, respectively, with 6.8% having both. Perceived risk factors included overwhelming academic workload (65.2%) and failure to meet up with academic expectations (64.1%). The predictors of comorbid anxiety and depression were: polygamous family setting (OR 2.7: 95% CI: 1.156-6.536) and preclinical studentship (OR: 6.2; 95% CI: 2.282-16.868). CONCLUSION: This study shows that the prevalence of mental health problems is high among medical students.

Lessons learned from the development of a hidradenitis suppurativa xenograft mouse model.

Hidradenitis suppurativa (HS) is a chronic inflammatory skin disease originating from the pilosebaceous unit, in which patients develop painful abscesses, sinus tracts, nodules and scarring, typically in intertriginous areas. Major gaps in our understanding of HS exist, and these may be partially due to the lack of an animal model for experimental studies. We developed an HS xenograft mouse model using human HS lesions grafted onto immunocompromised mice. Although the model had its limitations, several informative lessons were learned, which may contribute to future attempts at an HS animal model.

Specimen Collection for Translational Studies in Hidradenitis Suppurativa.

Hidradenitis suppurativa (HS) is a chronic inflammatory disorder characterized by painful nodules, sinus tracts, and scars occurring predominantly in intertriginous regions. The prevalence of HS is currently 0.053-4%, with a predominance in African-American women and has been linked to low socioeconomic status. The majority of the reported literature is  retrospective, population based, epidemiologic studies. In this regard, there is a need to establish a repository of biospecimens, which represent appropriate gender and racial demographics amongst HS patients. These efforts will diminish knowledge gaps in understanding the disease pathophysiology. Hence, we sought to outline a step-by-step protocol detailing how we established our HS biobank to facilitate the formation of other HS tissue banks. Equipping researchers with carefully detailed processes for collection of HS specimens would accelerate the accumulation of well-organized human biological material. Over time, the scientific community will have access to a broad range of HS tissue biospecimens, ultimately leading to more rigorous basic and translational research. Moreover, an improved understanding of the pathophysiology is necessary for the discovery of novel therapies for this debilitating disease. We aim to provide high impact translational research methodology for cutaneous biology research and foster multidisciplinary collaboration and advancement of our understanding of cutaneous diseases.

Stroke risk factors, subtypes, and 30-day case fatality in Abuja, Nigeria.

BACKGROUND: Stroke is the second leading cause of death and the leading cause of adult disability worldwide. A better understanding of stroke risk factors and outcome may help guide efforts at reducing the community burden of stroke. This study aimed to understand stroke risk factors, imaging subtypes, and 30-day outcomes among adult Nigerians. MATERIALS AND METHODS: We prospectively recruited all patients presenting with acute stroke at the National Hospital Abuja between January 2010 and June 2012. We assessed clinical and laboratory variables, as well as brain computerized tomography, magnetic resonance imaging, and carotid Doppler ultrasound scans. We also assessed case fatality and functional outcome at 30 days after stroke. RESULTS: Of 272 patients studied, 168 (61.8%) were males. Age at presentation (mean ± standard deviation) was 56.4 ± 12.7 years in males and 52.9 ± 14.8 years in females (P = 0.039). Neuroimaging was obtained in 96.7% patients, revealing cerebral infarction (61.8%), intracerebral hemorrhage (ICH) (34.8%), and subarachnoid hemorrhage (SAH) (3.4%). Carotid plaques or stenosis ≥50% were detected in 53.2% patients with cerebral infarction. Stroke risk factors included hypertension (82.7%), obesity (32.6%), diabetes (23.5%), hyperlipidemia (18.4%), atrial fibrillation (9.2%), and cigarette smoking (7.7%). At 30 days after stroke, case-fatality rate was 18.8%, whereas modified Rankin Scale (mRS) scores for cerebral infarction, ICH, and SAH were 3.71, 4.21, and 4.56, respectively. Atrial fibrillation, a previous stroke, and age older than 50 years were all associated with worse mRS scores at 30 days. CONCLUSION: Although hypertension, obesity, diabetes mellitus, and atrial fibrillation were important stroke risk factors, in many patients, these were detected only after a stroke. While the commonest stroke subtype was cerebral infarction, observed in almost two-third of patients, SAH was associated with the highest case-fatality rate at 30 days of 44.4%. Larger population-based studies may provide additional data on stroke incidence and outcome among Nigerians.

Aflatoxin exposure and viral hepatitis in the etiology of liver cirrhosis in the Gambia, West Africa.

BACKGROUND: Cirrhosis of the liver is thought to be a major cause of morbidity and mortality in sub-Saharan Africa, but few controlled studies on the etiology of cirrhosis have been conducted in this region. OBJECTIVES: We aimed to elucidate the association between environmental and infectious exposures and cirrhosis in The Gambia. METHODS: Ninety-seven individuals were diagnosed with cirrhosis using a validated ultrasound scoring system and were compared with 397 controls. Participants reported demographic and food frequency information. Blood samples were tested for hepatitis B surface antigen (HBsAg), hepatitis B e antigen (HBeAg), hepatitis C virus (HCV) antibody, HCV RNA, and the aflatoxin-associated 249(ser) TP53 mutation. RESULTS: HBsAg seropositivity was associated with a significant increase in risk of cirrhosis [odds ratio (OR) = 8.0; 95% confidence interval (CI), 4.4-14.7] as was the presence of HBeAg (OR = 10.3; 95% CI, 2.0-53.9) and HCV infection (OR = 3.3; 95% CI, 1.2-9.5). We present novel data that exposure to aflatoxin, as assessed both by high lifetime groundnut (peanut) intake and by the presence of the 249(ser) TP53 mutation in plasma, is associated with a significant increase in the risk for cirrhosis (OR = 2.8; 95% CI, 1.1-7.7 and OR = 3.8; 95% CI, 1.5-9.6, respectively). Additionally, aflatoxin and hepatitis B virus exposure appeared to interact synergistically to substantially increase the risk of cirrhosis, although this was not statistically significant. CONCLUSIONS: Our results suggest that the spectrum of morbidity associated with aflatoxin exposure could include cirrhosis.

The Gambia Liver Cancer Study: Infection with hepatitis B and C and the risk of hepatocellular carcinoma in West Africa.

Hepatocellular carcinoma (HCC) is the most common cancer in The Gambia. Hepatitis B virus (HBV) infection is endemic, with 15% to 20% of the population being chronic carriers, whereas hepatitis C virus (HCV) prevalence is low. We recruited 216 incident cases of HCC and 408 controls from three sites. HBV carriage was present in 61% (129/211) of HCC patients and 16% (64/402) of controls, whereas 19% (36/191) of HCC patients were HCV seropositive compared with 3% (11/382) of controls. HCC patients with HCV were notably older and were more likely to be female than those with HBV. Increased HCC risk was strongly associated with chronic HBV (odds ratio, 16.7; 95% CI, 9.7-28.7), HCV (16.7; 6.9-40.1), and dual infection (35.3; 3.9-323). We interpret the additive nature of risk with coinfection as representative of HBV and HCV acting primarily through shared steps in the multistage process of hepatocarcinogenesis. HCV infection was not observed among younger participants, suggesting a possible cohort effect. Reasons for the striking age and gender differences in HCC associated with HBV compared with HCV are unclear, but transmission patterns and age at exposure may be factors. In conclusion, in a standardized evaluation of well-characterized study participants from The Gambia, most cases of HCC are attributable to HBV (57%), but HCV adds a significant fraction (20%), especially among older patients and females. If HCV transmission is not perpetuated in future cohorts, focusing available resources on HB vaccination efforts could greatly ameliorate a major cause of cancer death in sub-Saharan Africa.

Management of the agitated patient.

Unfortunately, although delirium is common in the general hospital, the diagnosis is frequently missed. As delirium often indicates a serious, sometimes life-threatening, medical or surgical condition, successful management and subsequent prevention of morbidity and mortality require prompt recognition and early intervention. Failure to recognize, diagnose, and treat delirium and the underlying pathology can result in death. This article presents current thinking on the management of delirium and related agitation in the general medical hospital.
