Background: Parathyroid carcinoma is an exceptionally rare endocrine malignancy with poorly understood pathogenesis due to limited global data. It is often associated with unfavorable outcomes, largely attributable to delayed diagnosis and severe hypercalcemia. Aims and Objectives: To present the clinical, biochemical, radiological, and pathological features of parathyroid carcinoma. Settings: This study was a retrospective chart review conducted at the Endocrine Surgery Unit of the Royal Hospital, Muscat, Oman. Methods: The medical records of all patients with histopathologically confirmed parathyroid carcinoma between January 2012 and December 2023 were examined. Results: Four patients (three males, one female) with a mean age of 49 years were identified. Three patients were presented with symptomatic hypercalcemia, and one was diagnosed incidentally. Preoperative parathyroid hormone (PTH) levels were elevated in all patients, with one exceeding 80 times the upper limit of normal. All patients underwent surgical resection. Postoperative outcomes were favorable with no disease recurrence observed... Continue Reading

Background: Primary ciliary dyskinesia (PCD) is a rare genetic disorder characterized by structural and/or functional abnormalities of motile cilia. It typically presents with neonatal respiratory distress, recurrent respiratory infections and sometimes laterality defects, which define Kartagener syndrome. Diagnosis is often delayed due to nonspecific symptoms. Case Presentation: A 10-year-old female was referred to pediatric allergy consultation for perennial nasal obstruction and impaired growth. Her history included neonatal respiratory distress, hydrocephalus, situs inversus totalis, recurrent otitis media with hearing impairment and chronic rhinosinusitis. Genetic testing by whole-exome sequencing revealed a previously undescribed heterozygous frameshift variant in FOXJ1 (c.929_932del p.Asp310Glyfs*22), a gene crucial for motile cilia function and associated with autosomal dominant PCD. Chest computed tomography showed extensive bronchiectasis. She started multidisciplinary treatment including airway clearance, additional immunizations and prophylactic azithromycin. Conclusion: This case reinforces the importance of clinical suspicion for PCD when faced with characteristic symptoms to achieve early diagnosis and... Continue Reading

Background: Ginseng has been used as a traditional medicinal herb for thousands of years. It is used for the treatment of various ailments, including gastrointestinal disturbances, metabolic disorders like diabetes mellitus, and even cancer. However, indiscriminate use can lead to serious cardiac emergencies, as observed in a case of life-threatening ventricular tachycardia that developed after consuming ginseng for several days. Case Presentation: A 38-year-old woman was admitted to the emergency department (ED) with sudden-onset palpitations and recurrent episodes of syncope. On arrival, her ECG indicated an irregular rhythm marked by premature ventricular complexes that escalated into pulseless ventricular tachycardia (VT), necessitating defibrillation. Subsequent electrocardiogram (ECG) revealed a significantly prolonged QT interval. Treatment was initiated with intravenous magnesium and potassium (serum potassium 3 mmol/L), along with an oral beta-blocker (Metoprolol succinate 25 mg once daily). These interventions successfully prevented further VT episodes. It was later revealed that she had been taking... Continue Reading

Background: The coexistence of morphea and systemic lupus erythematosus (SLE) is rare and represents an important overlap of autoimmune disorders. This dual diagnosis highlights the complexity of immune dysregulation and poses challenges in clinical evaluation and management. Case Presentation: A 26-year-old female presented with an 11-month history of progressive, recurrent erythematous plaques on her arms, back, and knees, accompanied by fatigue and polyarthralgia. She developed generalized swelling involving the periorbital regions and lower extremities, worsening in the morning. Physical examination revealed non-tender, well-defined macules and plaques, some with central hyperpigmentation and others with peripheral hyperpigmentation and central hypopigmentation, along with generalized swelling. Laboratory tests showed pancytopenia, significant proteinuria, hematuria, elevated creatinine and blood urea nitrogen, raised inflammatory markers, liver dysfunction, positive rheumatoid factor, and positive ANA and anti-double stranded DNA antibodies. Skin biopsy demonstrated hyperkeratosis, epidermal atrophy, dermal collagenization, and periadnexal lymphocytic infiltrates. Conclusion: This case underscores the rare coexistence...

Patients with atrial fibrillation and ACS need triple antithrombotic therapy (double antiplatelet plus anticoagulant). In cases of ACS where a high thrombus burden exists, even in the absence of atrial fibrillation, triple antithrombotic therapy (double antiplatelet plus anticoagulant) is essential. Continue Reading
