A 52-year-old man presented with a history of sudden onset diplopia. On neurological examination, the only abnormality was a right-sided oculomotor (third nerve) palsy. A brain CT was performed and reported as showing no abnormality. ⋯ The patient underwent an emergency resection and made a good postoperative recovery. This case report showed the importance of considering a cardiogenic source of emboli in patients who present with cerebral infarcts. Performing echocardiography early will help to detect treatable conditions such as atrial myxoma, and prevent further complications.

Agranulocytosis is a rare yet life-threatening complication of methimazole therapy for hyperthyroidism. We present the case of a 37-year-old female recently started on methimazole for hyperthyroidism who presented to our facility for evaluation of suspected thyroid storm. In addition to having abnormal thyroid indices, she was noted to have an odontogenic abscess, and was septic with profound neutropenia. ⋯ Her neutrophil count improved significantly following cessation of methimazole and administration of granulocyte colony-stimulating factor. Diagnosis was initially confounded by the similarity between symptoms of early sepsis and those of thyroid storm. This case report discusses the factors leading to diagnostic delay and highlights the dangerous manifestations of neutropenia in patients on methimazole therapy.

We describe two patients with laryngeal cyst who underwent microlaryngeal surgery. Peroral rigid laryngoscopy, as an indirect endoscopy, performed via the transoral route, was evaluated as a routine screening tool of the difficult airway in patients with laryngeal neoplasm, in our hospital preoperatively. ⋯ As we saw in these two cases, endoscopic examination alone was inadequate for the assessment of a difficult airway, which may also lack the predictive sensitivity or may cause a high false positive. Usage of video laryngoscopy combined with intubating stylet will improve the intubation success in patients with huge epiglottic cyst.

A teenage boy with vertically acquired-HIV presented with bone pain of 6 months duration. His antiretroviral therapy (ART) consisted of tenofovir disoproxil fumarate (TDF), emtricitabine and ritonavir-boosted lopinavir. Plain X-rays showed stress fractures of metatarsals bilaterally. ⋯ This case uniquely features renal and skeletal toxicities with resultant metatarsal stress fractures. Children and adolescents on combined ART which include tenofovir should be screened for the early detection of proximal tubulopathy, with the measurement of renal function, phosphate, vitamin D and urinary phosphate excretion. Although uncommon and mostly reversible, recognition of tenofovir-related effects is paramount as prolonged exposure may lead to persistent renal tubular damage and osteomalacia.

Fetal supraventricular tachycardia (SVT) is the most common form of fetal tachycardia. If started early in pregnancy, it can cause non-immune fetal hydrops. Echocardiography is the preferred method for the diagnosis with simultaneous pulsed Doppler recording from the superior vena cava and ascending aorta. ⋯ We present a case of fetal SVT detected at 26 weeks of pregnancy. Digoxin therapy restored the rhythm initially, but later paroxysms of fetal SVT persisted necessitating the addition of second antiarrhythmic medication which was discussed with the parents. The couple chose to proceed for premature delivery at 32 weeks.
