Neuromyelitis optica spectrum disorder co-existing with antiphospholipid syndrome: A case report.

Key clinical message: Neuromyelitis optica spectrum disorder is an autoimmune disease, rarely presents with antiphospholipid syndrome. Diagnosis and management of NMOSD are challenging in the background of diverse presentations, especially in resource-limited settings. Abstract: Neuromyelitis optica spectrum disorder (NMOSD) is a progressive demyelinating autoimmune condition resulting from the autoantibodies produced against aquaporin-4 (AQP-4) proteins which are widely distributed in astrocytes in the nervous system. In the setting of NMOSD, it is very crucial to consider other autoimmune diseases as differential diagnoses or co-occurrences due to the diversity of symptoms. NMOSD co-exists with other autoimmune diseases such as myasthenia gravis, thyroid disease, ankylosing spondylitis, pernicious anemia, thrombotic thrombocytopenic purpura, ulcerative colitis, and systemic lupus erythematosus. Few cases of antiphospholipid syndrome co-existing with NMOSD have been reported. In resource-limited settings, the published data are scarce, and therefore, autoimmune diseases are poorly studied. Therefore, late diagnosis and delayed treatment initiation pose long-term sequelae and hence poor prognosis. Here, we present a case of an African woman in her early 40s presenting with bilateral progressive loss of vision, transverse myelitis, extensive longitudinal hyperintense T2 cervical lesion, and AQP-4 autoantibody keeping with NMOSD. The co-existence of antiphospholipid syndrome, in this case, was supported by a history of recurrent pregnancy loss and positive antiphospholipid antibodies. This case underscores the importance of individualized-based medicine, especially in resource-limited settings.

Diffuse type gastric adenocarcinoma with atypical presentation: A case report.

Key Clinical Message: Gastric adenocarcinoma can present uncommonly. This emphasizes the need for intensified vigilance in the absence of typical gastrointestinal symptoms, particularly in areas where infectious diseases are common. Abstract: Gastric adenocarcinoma, a common advanced-age global malignancy is typically associated with abdominal symptoms. However, atypical presentations such as back pain and respiratory distress particularly in younger patients represent diagnostic challenges. We present a case of a late-30s male who presented initially with back pain, shortness of breath, and constitutional symptoms. A diagnosis of tuberculosis was established presumptively with immediate initiation of treatment. Later on, he presented with abdominal pain and intractable vomiting. Oesophagoduodenoscopy (OGD), tissue histology, and immunohistochemistry confirmed a diffuse type gastric adenocarcinoma. He died as a result of complications from an advanced disease. This particular instance emphasizes the importance of maintaining a high index of skepticism even in atypical presentations, as well as the significance of prompt OGD alongside potential genetic testing if any. Gastric adenocarcinoma should be contemplated by clinicians in a variety of clinical scenarios, especially when handling younger patients from settings with limited resources to facilitate timely diagnosis and effective treatment.

Incidence and predictors of post-stroke cognitive impairment among patients admitted with first stroke at tertiary hospitals in Dodoma, Tanzania: A prospective cohort study.

INTRODUCTION: Stroke survivors develop cognitive impairment, which significantly impacts their quality of life, their families, and the community as a whole but not given attention. This study aims to determine the incidence and predictors of post-stroke cognitive impairment (PSCI) among adult stroke patients admitted to a tertiary hospital in Dodoma, Tanzania. METHODOLOGY: A prospective cohort study was conducted at tertiary hospitals in the Dodoma region, central Tanzania. A sample size of 158 participants with the first stroke confirmed by CT/MRI brain aged ≥ 18 years met the criteria. At baseline, social-demographic, cardiovascular risks and stroke characteristics were acquired, and then at 30 days, participants were evaluated for cognitive functioning using Montreal Cognitive Assessment (MoCA). Key confounders for cognitive impairment, such as depression and apathy, were evaluated using the Personal Health Questionnaire (PHQ-9) and Apathy Evaluation Scale (AES), respectively. Descriptive statistics were used to summarise data; continuous data were reported as Mean (SD) or Median (IQR), and categorical data were summarised using proportions and frequencies. Univariate and multivariable logistic regression analysis was used to determine predictors of PSCI. RESULTS: The median age of the 158 participants was 58.7 years; 57.6% of them were female, and 80.4% of them met the required criteria for post-stroke cognitive impairment. After multivariable logistic regression, left hemisphere stroke (AOR: 5.798, CI: 1.030-32.623, p = 0.046), a unit cm3 increase in infarct volume (AOR: 1.064, 95% CI: 1.018-1.113, p = 0.007), and apathy symptoms (AOR: 12.259, CI: 1.112-89.173, p = 0.041) had a significant association with PSCI. CONCLUSION: The study revealed a significant prevalence of PSCI; early intervention targeting stroke survivors at risk may improve their outcomes. Future research in the field will serve to dictate policies and initiatives.

Prevalence, clinical correlates and outcomes of cardiorenal anemia syndrome among patients with heart failure attending tertiary referral hospital in Dodoma, Tanzania: A protocol of a prospective observational study.

BACKGROUND: Cardiorenal anemia syndrome (CRAS) is a common complication among patients with heart failure and is associated with poor clinical outcomes. However, there is a paucity of published data concerning CRAS, despite of significant increase in heart failure patients attending medical services in developing countries. This study aims to assess the prevalence, clinical correlates, and outcomes of CRAS among patients with heart failure attending the Benjamin Mkapa Hospital in Dodoma, Tanzania. METHODOLOGY: A prospective observational study is ongoing at the Benjamin Mkapa Hospital in Dodoma, Tanzania. Currently, 92 patients have been recruited into this study and process is not yet completed. The socio-demographic data, clinical correlates, and prevalence of CRAS will be determined at baseline meanwhile, the outcomes of CRAS will be determined during a follow-up period of six months from the date of enrollment. CRAS is the primary outcome of the study. Data will be categorized into CRAS and non-CRAS during statistical analysis. Mean and standard deviation will be used for normally distributed continuous variables while median and interquartile range will be used for skewed data. Frequencies and percentages will summarize categorical variables. Clinical correlates and outcomes of CRAS will be analyzed and compared by using univariate and multivariate logistic regression and Cox proportional hazards models. A two-tailed p-value of less than 0.05 will indicate statistical significance.

Acute soft head syndrome in a teenager with sickle cell anemia: A case report.

Key Clinical Message: Sickle cell disease (SCD) rarely presents with acute soft head syndrome (ASHS) often posing a diagnostic dilemma. Recovery is typically spontaneous, however, in the context of lack of awareness and limited brain imaging it could potentially lead to poor outcome. Abstract: ASHS is a rare complication of SCD, invariably occurring near puberty with hitherto elusive pathogenic mechanisms. ASHS often resolves spontaneously on conservative management, however, lack of awareness in the context of limited access to brain imaging could pose diagnostic challenges resulting in inappropriate management and untoward outcome. We present a case of a teenager who presented with subtle symptoms for which the diagnosis of sickle cell anemia (SCA) was delayed until he developed ASHS. LTM was a 16 years old boy with a history of recurrent joints pain since the age of 6 years, with a family history of SCA, but had initial negative sickling test. He presented with episodes of multiple joints pain, unprovoked scalp and left orbital swelling, low-grade fever and mild headache without any evidence for bleeding diathesis. The diagnosis of SCA was confirmed by hemoglobin electrophoresis. Computed tomography (CT) scan of the head revealed subgaleal heamatoma (SGH) and intraorbital haematoma without intracranial hemorrhage (ICH). He was managed conservatively with analgesics and hydration together with antibiotics for associated sepsis with complete resolution of clinical symptoms within 2 weeks. This case represents a rare scenario for a relatively mild SCA phenotype presenting with ASHS whose diagnosis poses an enigma in the resource-limited contex. It is therefore, prudent to recognize ASHS to avoid judicious interventions which could potentially result in untoward clinical outcome.

Predictors and outcomes of cardiac dyssynchrony among patients with heart failure attending Benjamin Mkapa Hospital in Dodoma, central Tanzania: A protocol of prospective-longitudinal study.

INTRODUCTION: Cardiac Dyssynchrony is prevalent among patients with heart failure with high cost of care and potentially poor outcomes. Nevertheless, little is known about cardiac dyssynchrony among heart failure patients, especially in developing countries. This study aims at assessing the predictors and outcomes of cardiac dyssynchrony among heart failure patients attending the cardiology department at Benjamin Mkapa Referral Hospital in Dodoma, central Tanzania. METHODS: The study will follow a prospective longitudinal design involving participants aged 18 years and above with heart failure attending the Cardiology Department at Benjamin Mkapa Hospital. Heart failure will be identified based on Framingham's score and patients will be enrolled and followed up for six months. Baseline socio-demographic and clinical characteristics will be taken during enrollment. Outcomes of interest at six months include worsening of heart failure, readmission and death. Continuous data will be summarized as Mean (SD) or Median (IQR), and categorical data will be summarized using proportions and frequencies. Binary logistic regression will be used to determine predictors and outcomes of Cardiac Dyssynchrony among patients with heart failure.

Magnetic resonance imaging in the diagnosis of progressive supranuclear palsy: A case report and review of literature.

Key Clinical Message: Progressive supranuclear palsy (PSP) has many clinical features overlapping with other Parkinson syndromes and differentiation on clinical ground is difficult. This case highlights how a brain MRI can help diagnose PSP in settings with limited resources where histological diagnosis is difficult. Abstract: Progressive supranuclear palsy (PSP) may be challenging to diagnose due to its widely acknowledged clinical complexity and challenges with diagnosis confirmation, particularly in resource-poor settings where the ability to obtain confirmatory tests is highly complicated, leading to an inaccurate or incomplete diagnosis of PSP. This paper discusses using brain magnetic resonance imaging (MRI) to diagnose PSP, and a review of relevant literature addresses the diagnostic value of MRI in PSP.
