Superficial siderosis is a rare disorder characterised by the deposition of haemosiderin on the surface of the central nervous system. Cognitive dysfunction has sporadically been reported in relation with superficial siderosis. We present a 61-year-old man with cognitive dysfunction in the presence of the typical radiological image of temporal and cerebellar superficial siderosis, most likely due to pseudomeningocoele 14 years after resection of a meningioma at the cervicothoracic junction. Xantochromia was present on cerebrospinal fluid investigation and a source of bleeding was seen during surgical exploration. Despite surgical treatment of the suspected bleeding source, the patient deteriorated and neuropsychological examination 1 year after surgery showed progression of cognitive dysfunction to dementia. It is likely that in the absence of other typical symptoms such as cerebellar ataxia and hearing loss, the cognitive dysfunction was not related to the superficial siderosis.A 43-year-old woman was referred to the Ear, Nose and Throat Department with a 3-day history of left-sided neck pain and swelling associated with fevers and night sweats. She also reported a cough, oral thrush and a dental extraction more than a month previously. A CT scan of the neck with contrast revealed left internal jugular vein (IJV) thrombophlebitis and the patient was initially managed for suspected Lemierre’s syndrome. Subsequent investigations revealed a locally advanced metastatic colorectal adenocarcinoma as the cause of her thrombosis, which was deemed inoperable. The patient was referred to oncology and commenced on palliative chemotherapy.The incidence of thrombophlebitis in patients with cancer is high. Although the IJV is a relatively uncommon site of thrombus formation, IJV thrombophlebitis is associated with significant morbidity and mortality. UNC5293 Mertk inhibitor As it may be the first manifestation of an occult malignancy, a neoplastic cause should always be considered.An adult man was struck in the face by his own aerial drone. The propellers hit the upper face region leading to forehead and eyelid lacerations, a partial scleral laceration, conjunctival laceration, hyphaema, traumatic iritis and forward displacement of one haptic of the intraocular lens from a previous cataract surgery. In the last decade, drone use has significantly increased and drone-related injuries have become an emerging cause of trauma. Our case raises awareness of the risks and highlights the need for improvement in regulation of drone use.A 31-year-old immunocompetent, heterosexual man with no relevant medical history presented with 1 week of jaundice, abdominal pain, cough and headache. Examination revealed scleral icterus, right upper quadrant tenderness and hepatomegaly. Initial investigations revealed hyperbilirubinaemia and elevated transaminases. Serum studies were positive for antinuclear antibodies, antimitochondrial antibodies, and herpes simplex virus IgM. Despite being started on intravenous acyclovir, his bilirubin and transaminase levels continued to rise. He was subsequently tested for syphilis given his maculopapular rash on the soles of his feet and it returned positive. He improved clinically with the initiation of penicillin. In this case, we will discuss the presentation, diagnosis and treatment of syphilitic hepatitis.A 73-year-old white man presents with left-sided ptosis and diplopia in the absence of ophthalmoplegia, with left hemibody paresthesia. He reports intermittent dysphagia and dizziness for 1 month and diarrhoea for 2 months. Serum and electrodiagnostic studies confirmed the diagnosis of myasthenia gravis. This case highlights the non-classic presentation of myasthenia gravis in the absence of ophthalmoplegia with a unique unexplained hemisensory deficit.Misguided encouragement to consume large volumes of water during labour for pain relief results in dilutional hyponatraemia in mothers and their babies presenting with neurological dysfunction. We report three babies who were encephalopathic with seizures in the background of hyponatraemia secondary to maternal ingestion of large volumes of water and mild perinatal asphyxia. All babies underwent therapeutic hypothermia in addition to sodium supplementation with fluid restriction. Their neurodevelopment was appropriate for age. This case series highlights the dilemma that could arise with hyponatraemic encephalopathy and mild perinatal asphyxia in the first 6 hours of life, which is the window of opportunity for therapeutic hypothermia for hypoxic-ischaemic encephalopathy. It is important to educate pregnant mothers in labour on the adverse effects of excessive fluid ingestion.Disulfiram has been widely used for over six decades in the treatment of alcohol dependence, as an aversive therapeutic agent. Despite having very few side effects when taken without concurrent alcohol consumption, some of these may underlie serious clinical complications. Epileptic seizure induction is a rare adverse effect of disulfiram and its aetiological mechanism is unknown. We present a hospitalised 47-year-old male patient with two episodes of generalised tonic-clonic seizures during treatment with disulfiram while abstinent from alcohol.A 72-year-old male patient presented to the hospital because of sudden inability to bear weight and without a history of trauma. A fracture of the head of the femur was identified on CT scan of the pelvis. In his history, the patient had a hospital admission 3 months earlier, during which he had a urinary catheter, and a urine specimen was analysed. The same pathogen was found in the patient urine and in the head of the femur specimen. This is a report of blood-borne spread of Serratia marcescens infection from the urothelium to the hip joint, responsible for spontaneous fracture of the femoral head without history of trauma.This 18-year-old boy presented to the hospital with symptoms of cerebellar dysfunction preceded by an acute febrile illness with rash. Examination showed evidence of left-sided cerebellar dysfunction and polyneuropathy. Empirical treatment for leptospirosis and scrub typhus was initiated. MRI was normal. Other organ dysfunctions in the form of thrombocytopenia and transaminitis were also observed. He recovered without sequelae. A diagnosis of acute cerebellar ataxia and polyneuropathy due to scrub typhus was made.
