Bilateral ischaemic optic neuropathy and retinopathy along with cortical infarct in a case of Takayasu disease

Description

A 27-Year-old female presented with complaints of sudden onset visual loss along with right sided deviation of the angle of mouth since past 30 days. Vision loss had worsened in the last week. There was history of severe headache which was not associated with vomiting. There was no history of any other neurological deficit or prior systemic illness. Examination for cranial nerve function revealed a left sided upper motor neuron facial nerve palsy and rest of the neurological examination was within normal limits. On ocular examination, the patient had best-corrected visual acuity of light perception (PL) in right eye (RE) and 6/36 in left eye (LE). A grade four relative afferent pupillary defect was noted in RE, while slit lamp examination and tonometry were normal. On fundus examination, RE optic disc had yellowish-white pallor while LE optic disc had temporal pallor (figure 1A,B). Multiple retinal...

Saksenaea vasiformis infection in an immunocompetent patient in rural Australia

An 81-year-old man from rural Australia presented with right pretibial cellulitis 7 days after minor trauma against furniture. He failed to improve despite antibiotics and surgical debridement. Subsequent cultures grew the rare fungus Saksenaea vasiformis, which was treated with further surgical debridement, amphotericin B and posaconazole. This was successful and the patient made a full recovery. We present the case and discuss lessons learnt.

QUAD fever: beware of non-infectious fever in high spinal cord injuries

A case of cervical spinal cord injury and quadriparesis with prolonged fever is being described. Initially, the patient received treatment for well-documented catheter-related bloodstream infection. High spiking fever returned and persisted with no obvious evidence of infection. The usual non-infectious causes too were carefully excluded. QUAD fever or fever due to spinal cord injury itself was considered. The pathogenetic basis of QUAD fever is unclear but could be attributed to autonomic dysfunction and temperature dysregulation. Awareness of this little known condition could help in avoiding unnecessary antimicrobial therapy and in more accurate prognostication. Unlike several previous reported cases that ended fatally, the present case ran a relatively benign course. The spectrum of presentations may therefore be broader than hitherto appreciated.

Tumour necrosis factor (TNF) inhibitor-induced isolated pleural granulomas: a rare adverse effect

A 53-year-old man with a history of Crohn's disease on infliximab, presented with several weeks of cough and dyspnoea. He had a right-sided pleural effusion, found to be exudative with lymphocytic predominance. He underwent right-sided video-assisted thoracic surgery (VATS) with biopsies and pleurodesis. Histopathology showed pleural-based non-caseating granulomas with unremarkable lung parenchyma. Cultures were only positive for Propionibacterium acnes. 8 months later, he was found to have a left-sided exudative, lymphocytic predominant pleural effusion. Left-sided VATS and biopsies again showed pleural-based non-caseating granulomas with normal lung parenchyma. Having ruled out an active infection and malignant lesions, we diagnosed infliximab-induced pleural granulomas. Infliximab was stopped. The patient continues to do well at 6 years of follow-up. We believe this is the first report of tumour necrosis factor (TNF) inhibitor-induced isolated pleural granulomas. P. acnes and cytokine imbalance might be responsible for the pathogenesis of TNF inhibitor-induced granulomas.

A case of recurrent, multifocal anastomosing haemangiomas

Anastomosing haemangiomas are relatively rare lesions, with a renal predilection, and which, given their imaging and pathologic appearance, mimic aggressive malignancies such as angiosarcoma. The imaging characteristics of this case are informative when evaluating a vascular lesion of the adrenal gland.

Internal carotid artery occlusion and stroke as a complication of cisplatin-based chemotherapy for metastatic testicular germ cell tumour

Testicular tumours are the most common tumours in young men. Germ cell tumours (GCTs) account for 95% of all testicular cancers, and the non-seminomatous type (NSGCT) accounts for 50% of all GCTs. Cisplatin-based chemotherapy is curative in up to 90% of patients, but it is not without its inherent risks. Ischaemic stroke is a very uncommon, but severe complication of cisplatin-based chemotherapy. Strokes in young patients cause a disproportionately large economic impact by leaving victims disabled during their most productive years and strains the healthcare system with expensive hospital stays. We present a case of a young male patient with past medical history of metastatic NSGCT with the sudden onset of dysarthria, left hemiplegia and ipsilateral hemisensory loss 3 days after receiving cisplatin-based chemotherapy. Subsequent studies revealed a stroke involving the right middle cerebral artery territory secondary to an acute right internal carotid occlusion.

Ominous triad triggered by high-dose glucocorticosteroid therapy

Glucocorticosteroids (CS) play a key role in the treatment of numerous diseases. Nonetheless, they can be accompanied by several adverse effects. We present the case of a 51-year-old woman who was treated with high-dose CS for a relapse of her multiple sclerosis. After 5 days of treatment, the patient developed severe diabetic ketoacidosis, hypertriglyceridemia and acute pancreatitis—a potentially life-threatening triad which has previously been described, in our case, however, for the first time as a complication of CS therapy. Our patient's condition was further aggravated by a circulatory shock, haemodynamic relevant bleeding from a duodenal ulcer and psychotic symptoms. In the intensive care unit, intravenous insulin infusion, fluid resuscitation, catecholamine support, electrolyte supplementation, endoscopic haemoclipping and antibiotic and antipsychotic treatment were administered, leading to a continuous improvement of the patient's health state.

Chest X-ray of a patient with history of pleural effusion

The presented chest X-ray depicts the thoracic duct anatomy of a 50-year-old man who underwent heart transplantation. His postoperative course was complicated by Candida mediastinitis, treated with débridements and closure of the anterior chest wound with myocutaneous flaps. Postoperatively, he had persistent output from a right-sided chest tube. The fluid appeared milky and its triglycerides level was elevated at 254 mg/dL. The drainage persisted despite a low fat diet. The interventional radiologist identified a leak in the upper thoracic duct. It was embolised with coil and onyx. After the procedure, the chylous pleural effusions resolved. The thoracic duct has been visualised on subsequent chest X-rays (figures 1 and 2).

Port site endometrioma: a rare cause of abdominal wall pain following laparoscopic surgery

Endometriomas are a rare cause of abdominal wall pain. We report a case of a port site endometrioma presenting with an umbilical swelling. The patient underwent a laparoscopy for pelvic endometriosis 6 months previously and presented with a swelling around her umbilical port site scar associated with cyclical pain during menses. Ultrasound scan reported a well-defined lesion in the umbilicus and MRI scanning excluded other pathology. As she was symptomatic, she underwent an exploration of the scar and excision of the endometrioma with resolution of her symptoms. Precautions should be taken to reduce the risk of endometrial seeding during laparoscopic surgery. All tissues should be removed in an appropriate retrieval bag and the pneumoperitoneum should be deflated completely before removing ports to reduce the chimney effect of tissue being forced through the port site. The diagnosis should be considered in all women of reproductive age presenting with a painful port site scar.

Multipathogenic necrotising supraglottitis in an immunocompetent patient

Supraglottitis is a potentially life-threatening condition. It is now uncommon due to the Haemophilus influenzae type B vaccination and is more recently caused by Streptococcus pneumoniae, S. pyogenes, H. influenzae non-type B, H. parainfluenzae, Staphylococcus aureus and Pasteurella multocida. Very rarely, it can cause necrotising supraglottitis/epiglottitis, and this has been reported in immunocompromised individuals. We present a unique case of multipathogenic supraglottitis causing laryngeal fibrinoid necrosis in an immunocompetent patient. During his admission, the patient was critically unwell and required surgical intervention and tracheostomy. However, he made a full recovery with no persisting morbidity. We believe that this was owed to the aggressive antimicrobial therapy, timely surgical management of the disease process and the patientâ™s immunocompetency.

An unusual case of Escherichia coli O157:H7 infection with pseudomembranous colitis-like lesions associated with haemolytic-uraemic syndrome and neurological sequelae

A 75-year-old man was admitted with abdominal pain and fresh rectal bleeding. Significantly, he had no risk factors for Clostridium difficile infection. An abdominal CT demonstrated colonic thickening, and flexible sigmoidoscopy identified pseudomembranous colitis-like lesions. After initial treatment as C. difficile colitis, a stool sample revealed Escherichia coli O157:H7 infection. Antibiotic therapy was stopped due to the risk of lysis-mediated toxin release, but unfortunately, the patient continued to deteriorate. He developed several of the severe sequelae of E. coli O157:H7 infection, including haemolytic-uraemic syndrome with an acute kidney injury necessitating haemofiltration, plus progressively severe seizures requiring escalating antiepileptic treatment and intubation for airway protection. After a prolonged intensive care admission and subsequent recovery on the ward, our patient was discharged alive.

Lower Extremity Abscess Formation in Premature Infants due to Routine Infant Vaccinations

Since the introduction of vaccines, the impact of vaccinations has been immeasurable. Under the current immunization guidelines, infants receive the first of their routine infant vaccinations at 2 months of age. While the benefits of routine infant vaccinations in premature infants have been demonstrated, there is relatively little data on the dosing of these vaccines in premature infants. The medical records of two premature infants who developed intramuscular abscesses after receiving their routine infant vaccinations were reviewed. Both patients developed pain in the area of the injection after receiving their vaccinations. Magnetic resonance imaging findings confirmed the formation of an abscess. No other causes of abscess formation were observed. Both patients required surgical intervention and were treated with a course of antibiotics. To our knowledge, this is the first case report to suggest routine vaccinations as a potential cause of abscess formation in premature infants.
