Traumatic optic neuropathy is sinister sequelae of craniofacial trauma leading to vision loss. The decision between early medical or surgical intervention is usually individualised. Visual evoked potentials may guide the treatment plan. We describe a young male presenting 5 days after a road traffic accident with no perception of light vision in the right eye. He was managed medically with high dose of intravenous steroids. At the 3-month follow-up, he reported a reversal of vision loss with return of visual acuity to 3/60, which improved to 6/36 at 5 months and remained stable at 8 months.We report a novel case of a patient who presented with new diagnoses of both cytoplasmic antineutrophil cytoplasmic antibodies (c-ANCAs) positive vasculitis and chronic lymphocytic leukaemia (CLL). The patient was a 79-year-old man who presented with melena, haemoptysis, acute hypoxia and acute kidney injury. In the current literature, there are rare associations of c-ANCA vasculitis and malignancy, but very few, if any, relating c-ANCA vasculitis and CLL. This case is unique due to the presence of both pathologies and an uncommon presentation of the vasculitis. He presented with renal and pulmonary findings, unlike the dermal manifestations commonly seen with vasculitis. We think that this could be an easily overlooked combination of diseases and, therefore, the purpose of this case is to prevent delays in care that could affect patient outcomes and also to encourage further research into the relationship between these diseases.We present a case of a 49-year-old woman diagnosed with aquaporin-4 antibody-positive transverse myelitis, who developed a significant transaminitis 2 months after commencing mycophenolate mofetil (MMF) as a steroid-sparing agent. No other risk factors were identified, a blood liver panel was negative and liver biopsy showed features compatible with drug-induced liver injury (DILI). MMF was stopped with a corresponding normalisation of serum alanine aminotransferase over the next 2 months. This case highlights MMF as a rare cause of DILI and provides justification for monitoring of liver biochemistry on therapy.We present the case of a 29-year-old south Asian man born of consanguineous marriage, presenting with ataxia, peripheral neuropathy and cognitive impairment. An initial diagnosis of coeliac disease was thought to explain the pertinent clinical features; however, further investigation led to an additional diagnosis of the rare yet treatable autosomal recessive condition, cerebrotendinous xanthomatosis. With both conditions employing highly diverse and overlapping clinical phenotypes, this contributed to a delay in diagnosis. Our report highlights the importance of paying close attention to both the clinical phenotype and family history.Enterococcus hirae, a member of the Enterococcus genus, is known to cause infections, including infective endocarditis (IE), in animal species. In humans, E. hirae is an uncommon pathogen, but has been associated with severe and recurrent disease. Here, we report the first Danish case of E. hirae native aortic valve IE in a 62-year-old woman with no history of heart disease. She presented to the hospital with symptoms of gastroenteritis but no signs of heart disease. Nevertheless, blood culture revealed growth of E. hirae, and a transoesophageal echocardiography demonstrated a mobile mass adherent to the aortic valve, compatible with a vegetation. The patient was successfully treated for E. hirae native aortic valve IE with 4 weeks of intravenous benzylpenicillin in combination with gentamicin for the initial 2 weeks. To the best of our knowledge, this is the first documented case of E. [https://www.selleckchem.com/products/salubrinal.html Salubrinal] hirae IE in Denmark and the sixth documented case worldwide.A 64-year-old man had a several year history of B prolymphocytic leukaemia (PLL) which behaved indolently and had not required any treatment. Five years after diagnosis, he developed hypoalbuminaemia associated with severe lower-limb oedema, consistent with systemic capillary leak syndrome (SCLS). He recovered spontaneously but went on to have three further increasingly severe and protracted episodes over the subsequent 18 months. There was no identifiable precipitating factor for these episodes, but his peripheral lymphocyte count continued to increase slowly. The start of treatment for his PLL with chemoimmunotherapy was followed by a rapid resolution of residual oedema and normalisation of serum albumin. He has had no further attacks of SCLS in the 14 months since he started therapy for PLL. SCLS is a rare consequence of haematological malignancy which may show an excellent response to treatment of the haematological disease.Cholecystocolonic fistula with associated idiopathic megabowel (megacolon and megarectum) is a rare presentation as acute large bowel obstruction. Frequently presenting with chronic constipation, acute bowel obstruction is rarely encountered in the presence of concomitant cholecystocolonic fistula. This presents diagnostic and management difficulties with no consensus on appropriate surgical approach. This case highlights the outcomes following emergency total colectomy and subtotal cholecystectomy as a single-stage procedure for a 68-year-old man presenting with cholecystocolonic fistula secondary to idiopathic megabowel as acute large bowel obstruction.Cavernous sinus thrombosis (CST) is a rare and potentially fatal complication of acute sinusitis. Timely diagnosis and management is, therefore, essential in preventing death and neurological disability. Here, we describe the case of a paediatric patient with bilateral CST secondary to acute unilateral pansinusitis that presented with rapidly progressing bilateral periorbital oedema. Initial imaging was negative. This case serves to emphasise the importance of maintaining a high index of suspicion when managing paediatric patients with suspected CST with persistent symptoms. Expeditious investigation and management of our patient in this case resulted in a positive outcome, with resolution of symptoms and no residual neurological deficit.Cholangiocarcinomas are rare and often diagnosed late. Clear cell histology is a rare variant of such cancers. We report one such case of a man in his late 60s, with a history of excess alcohol intake, who was found to have deranged liver biochemical tests incidentally during an admission for an allergic reaction. Subsequent imaging to investigate this suggested a diagnosis of perihilar cholangiocarcinoma (ultrasound, CT, MRI, cholangiogram). Biopsy confirmed this to be of clear cell type on histology and immunohistochemistry. Diagnosis and further management of this rare entity was conducted in multidisciplinary meetings with the regional hepatobiliary centre. The patient was deemed unsuitable for surgical resection, underwent chemotherapy but died 1 year later.
