Systemic lupus erythematosus associated with erythema multiforme: A rare case report of Rowell's syndrome.

Key Clinical Message: Although it is very uncommon, SLE may initially present with recurrent episodes of EM-like rash. Despite the various possibilities underlying their association, prompt identification, and treatment of SLE in patients presenting with EM is important to prevent death or serious organ damage. Abstract: Rowell's syndrome (RS) is an uncommon presentation of systemic lupus erythematosus (SLE) with erythema multiforme (EM)-like lesions associated with specific serological changes, including positive rheumatoid factor (RF), speckled antinuclear antibody (ANA), positive rheumatoid factor, or anti-La antibodies in the serum. Our case, a 41-year-old male, presented with features of EM. Upon investigation, we identified underlying systemic lupus erythematosus, marking a rare instance of SLE presenting for the first time as EM. Classical or true EM is precipitated by trigger factors such as infective agents like the herpes simplex virus, Mycoplasma pneumoniae, drugs like anticonvulsants, antibiotics, and non-steroid anti-inflammatory drugs, any underlying malignancy, or connective tissue disorders, and is not associated with any specific serological abnormalities. EM cases associated with LE lesions where an EM trigger factor is missing are considered an RS diagnostic criterion. In this case report, the importance of considering SLE in patients presenting initially with recurrent episodes of EM-like rash is emphasized. RS should be considered, especially when there is no evidence of triggering factors. Early diagnosis and prompt treatment of SLE are crucial to preventing death and irreversible organ damage.

Dolutegravir-induced acquired sideroblastic anemia in a HIV positive patient: A challenging hematologic complication.

Dolutegravir, the most recent antiretroviral drug with high efficacy, good tolerability, infrequent drug-drug interactions, and a favorable safety profile has not been reported in current literature as a cause of acquired sideroblastic anemia. Here, we present a 35-year-old male patient who was diagnosed with acquired sideroblastic anemia to Dolutegravir therapy.

Median nerve schwannoma with a diagnostic delay of 8 years: a case report.

Introduction: Schwannomas are benign tumors of the peripheral nerve sheath, and the median nerve is the most commonly involved nerve. These benign tumors of the peripheral nerve sheath are very rare; they are clinically and radiologically similar to most other benign swellings of the hand; thus, they are often misdiagnosed. Case Presentation: A 41-year-old lady presented with an 8-year-long history of swelling over the distal forearm. The tumor measured 3.5×3.5×3.5 mm and was located over the flexor aspect of the distal part of her right forearm. Schwannoma was suspected from the clinical presentation and imaging, but the final diagnosis was established only after the surgery and histopathological analysis. At the follow-up after 1 year, the patient is doing well and her symptoms have not recurred. Conclusion: Imaging characteristics of schwannoma can be misinterpreted as some other condition, making the preoperative diagnosis very difficult and important. Thus, clinicians should be aware of such swellings, especially those that have been unnoticed or misdiagnosed, and provide optimal diagnoses to confer good outcomes.

Correlation of Body Mass Index and Oxygen Saturation in Chronic Obstructive Pulmonary Disease Patients at a Tertiary Care Center in Nepal: A Cross-Sectional Study.

Purpose: Chronic obstructive pulmonary disease (COPD) is a major cause of mortality and morbidity worldwide. COPD is associated with clinically relevant pulmonary and extrapulmonary manifestations, including hypoxemia and weight loss. The correlation of body mass index (BMI) and oxygen saturation (SpO2) with COPD grades may provide a useful additional marker for understanding and managing the disease. The aim of the study was to study the correlation of BMI and oxygen saturation with COPD in patients presenting to a tertiary care center in Nepal. Patients and Methods: A descriptive cross-sectional study was conducted among 145 COPD patients visiting the Department of Medicine in Shree Birendra Hospital between 1 March 2019 and 28 February 2020. A non-probability purposive sampling method was used and data were analyzed using SPSS version 21. A p-value of <0.05 was considered significant. Results: Out of 145 COPD patients, 58 (40%) were underweight, 53 (36.55%) were of normal weight, 20 (13.79%) were overweight, and 14 (9.6%) were obese. The number of underweight patients was highest in COPD grade 4 and lowest in COPD grade 1. The proportion of subjects with underweight BMI and hypoxia increased with COPD severity, and both were statistically significant (p-values <0.01). Conclusion: Our study shows that BMI and oxygen saturation have an inverse association with COPD severity. The correlation of BMI and oxygen saturation with COPD grade could provide a supplementary marker of disease severity, which could be useful in the understanding of the disease process and subsequent management of COPD.

Spectrum of Thyroid Disorders in Patients with Type-2 Diabetes Mellitus.

BACKGROUND: Diabetes mellitus and thyroid disorders are the two most common endocrine disorders and they mutually affect each other. There are very few researches from Nepal that have evaluated the association of type-2 diabetes mellitus and thyroid dysfunction. The main objective of this study was to evaluate the prevalence and spectrum of thyroid dysfunctions among type-2 diabetes mellitus patients. METHODS: This was cross-sectional study conducted among 204 type-2 diabetes mellitus patients visiting the internal medicine department of a tertiary center located in Kathmandu, Nepal. RESULTS: The prevalence of thyroid disorders in patients with type-2 diabetes mellitus was 27.94%. Subclinical hypothyroidism, which occurred in 14.71% of patients, was the most common thyroid disorder. The longer duration of diabetes, more than ten years, was associated with the increased thyroid disorders (p=0.025). The poor glycemic control, HbA1c ≥ 7%, was associated with significantly increased prevalence of thyroid dysfunction in type-2 diabetes mellitus patients (p=0.002). Female patients had higher prevalence of thyroid disorders than males, but this association was not statistically significant. CONCLUSIONS: The higher prevalence of thyroid disorders among patients with type-2 diabetes mellitus highlights the importance of screening type-2 diabetes mellitus patients for the presence of thyroid disorders.
