Background: Medical students encounter various stressors during their studies. The study aimed to assess stress levels, sources, and associated determinants among Sudanese medical students. Method: An online questionnaire-based study was conducted among 617 undergraduate medical students of 6 different universities in Sudan. A 19-item questionnaire was utilized to assess stress sources, in addition to demographics, stress manifestations, and coping strategies. Results: The overall prevalence of stress was 31.7% (p < 0.05). The main sources of stress were time pressure, heavy workload, fear of failure, and examination frequency. One-third of students indicated that they experienced at least one source of psychosocial- and teaching-related stress. Female medical students were more significantly stressed due to academics than males. Also, fourth- and fifth-year students were academically more stressed in comparison to the first-year students. Poisson regression analysis model showed that first-year students were less stressed than the final-year students in relation to academics (odds = 0.888, P = 0.003). Male medical students, across all study years, were far less stressed than females (odds = 0.901, P = 0.000153). Expectedly, ‘studying medicine by choice’ was associated with decreased odds for psychosocial stressors (odds = 0.885, P = 0.00781), and improved model-fit (chi-squared = 6.8952, P = 0.008643). Also, the year of study was a predictor of teaching-related stress development. Conclusions: Female medical students were more stressed due to academics than males. On the other hand, final-year students were more academically stressed than first-year students. Female medical students were likely having stress related to academic stress development, while being first-year medical student was a predictor of not developing academic stress. Studying medicine by choice’ was associated with ability to cope against stress.

Background: Bardet–Biedl syndrome is a rare multisystem autosomal recessive disorder that falls under the spectrum of ciliopathy disorders. It is characterized by rod–cone dystrophy, renal malformations, polydactyly, learning difficulties, central obesity, and hypogonadism. Many minor features that are related with Bardet–Biedl syndrome might aid in diagnosis and are crucial in clinical management. Bardet–Biedl syndrome is diagnosed on the basis of clinical signs and symptoms, which can be confirmed by genetic testing. Here we present four cases of Bardet–Biedl syndrome. To our knowledge, these are the first cases of Bardet–Biedl syndrome reported from Sudan.Case presentation: Here, we report four Sudanese patients who presented with a variety of clinical manifestations of Bardet–Biedl syndrome (two males, 50 and 16 years old; two females, 38 and 18 years old). The first two patients presented with features of chronic kidney disease. The third patient had recently been diagnosed with type 1 diabetes and diabetic ketoacidosis. The fourth patient showed signs of retinal dystrophy early on. Case 1: a 38-year-old female presented with vomiting and irritability; the patient was diagnosed with Bardet–Biedl syndrome as she fulfilled six items of the primary features (obesity, retinitis pigmentosa, post-axial polydactyly, renal abnormalities, learning disabilities, and genitourinary malformations), as well as one secondary feature (cardiovascular involvement, that is, left ventricular hypertrophy). Case 2: a 50-year-old male presented with fatigability; the patient was diagnosed with Bardet–Biedl syndrome as he fulfilled four items of the primary features (obesity, retinitis pigmentosa, post-axial polydactyly, and renal abnormalities) in addition to two secondary features (diabetes mellitus and cardiovascular involvement, that is, left ventricular hypertrophy). Case 3: an 18-year-old female presented with polyuria, polydipsia, weight loss, and epigastric pain for 2 days; the patient was diagnosed with Bardet–Biedl syndrome because he had four major features (retinal dystrophy, post-axial polydactyly, obesity, and learning disabilities) in addition to three secondary features (developmental delay, diabetes mellitus, and strabismus). Case 4: a 16-year-old male presented with a blurring of vision; the patient was diagnosed with Bardet–Biedl syndrome as he exhibited four major features (retinal dystrophy, post-axial polydactyly, obesity, and learning disabilities) plus two secondary features (developmental delay and cataract).Conclusion: The scarcity of Bardet–Biedl syndrome necessitates a high index of suspicion to diagnose this syndrome. Increased awareness among physicians is required for the early diagnosis and treatment of Bardet–Biedl syndrome and to avoid complications and mortality.

Introduction. Tetanus is still a major health issue, especially in rural areas, and is associated with high morbidity and mortality rate. This study was conducted to describe the pattern of presentation and treatment outcome among adult patients infected with tetanus in our environment. Materials and Methods. This is a descriptive retrospective hospital-based study conducted in Wad Medani teaching hospital, central Sudan. A total of thirty-one patients were enrolled in this study in the period between January 2018 and December 2020. Results. Thirty-one patients were infected with tetanus during the study period. They were 23 (74.2) males and 8 (25.8) females with a male-to-female ratio of 2.875:1. Their ages ranged from 20 to 70 years, and most of them (48.4) were free workers. Acute injuries were the most common portal of entry (64.51), and commonly involved the lower limbs (48.38). Lock jaw (54.8), muscle spasm (51.6), and neck pain and stiffness (45.2) were the most common presentation. Supportive measures along with surgical toilet and debridement, human tetanus immunoglobulin, antibiotics, and muscle relaxants were initiated in all patients. The most common antibiotics used were Penicillin V and Ceftriaxone. A muscle relaxant was administered to aid in relieving the spasms. Complication rate was 61.29 and included pulmonary and cardiovascular complications. Fifteen patients died accounting for an overall mortality rate of 48.4. Conclusions. Tetanus remains a disease with high morbidity and mortality. The unknown/incomplete vaccination status among study participants, inadequate management, and lack of equipped resources lead to a devastating outcome as in Sudan.

Computer vision syndrome (CVS) refers to a set of eye-related symptoms that arise from prolonged computer usage. A survey was conducted to investigate the demographic characteristics, factors contributing to, and preventive measures against CVS. Out of 159 participants, 31.0% experienced seven or more symptoms, indicating a notable prevalence. The study found no significant correlation between age or academic years and CVS occurrence (P values of 0.481 and 0.392, respectively). However, gender exhibited a statistically significant relationship, with females students showing a higher prevalence than males (P=0.018; τ=0.105*). Notably, the distance from the screen had a highly significant inverse correlation with CVS occurrence (P=0.000; τ=−0.207**), indicating that greater distance reduced the risk. Additionally, using a screen filter (P=0.000; τ=0.184**) and adjusting screen brightness (P=0.017; τ=0.101*) were associated with CVS occurrence. Among preventive measures, only the use of an anti-glare screen showed a significant association with reducing CVS risk (P=0.018; τ=−0.099*). Given these findings, raising awareness about CVS among medical students is recommended, especially as curricula in medical colleges evolve.

Background: Idiopathic intracranial hypertension is a rare neurological disorder of unknown etiology. It is characterized by symptoms and signs of raise intra cranial pressure, normal brain neuroimaging, and high opening pressure ≥ 280 cm H2O in the presence of normal cerebro spinal fluid constituents. Case presentation: Ten years old thin boy presented with severe throbbing headache, vomiting, and visual obscurations for a duration of 10 days. Physical examination revealed body mass index of 14.8, VI and VII cranial nerve palsies. Fudoscopy showed grade 4 papilledema; brain CT and MRI were normal. Lumbar puncture revealed pressure of 300 cm H2O with normal CSF constituents. He was treated with acetazolamide, methylprednisolone, and paracetamol. Conclusion: Pediatricians need to be more aware of idiopathic intracranial hypertension as it can lead to permanent vision loss.

Hemothorax after snake bite is very rare and unusual presentation. Administration of antivenom with supportive measures and close monitoring can prevent further deterioration. Delays in the transportation of patients to health facilities where antivenom and other therapeutic resources are provided can lead to devastating consequences.
