Emerging data suggest that patients with certain comorbidities requiring intensive care unit (ICU) admission for COVID-19 have a poor prognosis. This report describes a case of a patient with multiple comorbidities who contracted COVID-19 pneumonitis but was successfully weaned off invasive mechanical ventilation after 118 days, despite his admission being complicated by recurrent septic episodes and requirement for advanced cardiovascular support and renal replacement therapy. Of note, our patient received three courses of steroids in total during his ICU stay,and current literature strongly supports the use of steroids in critically unwell patients with COVID-19. To the best of our knowledge, this is the longest reported ventilated time and intensive care/hospital stay for a surviving patient with COVID-19 and highlights the importance of allowing sufficient time for clinical interventions to take effect, even when the prognosis appears bleak.Chlamydia trachomatis is a Gram-negative bacterium that causes urogenital tract infections, and ocular infections including trachoma, neonatal conjunctivitis and adult chlamydial inclusion conjunctivitis. A positive C. trachomatis diagnosis in children often raises suspicions of sexual abuse. While outer membrane protein A (ompA) genotypes A-C are non-invasive and are associated with trachoma; ompA genotypes D-K are often associated with sexually transmitted urogenital infections or sexually acquired chlamydial conjunctivitis. A 10-year-old female presented with a 7-month history of unilateral conjunctivitis with itching, watering and hyperaemia. She had recently moved from an urban centre in Afghanistan to the UK. A conjunctival swab taken from the child tested positive for C. trachomatis Application of ompA genotyping to conjunctival swab chlamydial DNA demonstrated that the C. trachomatis had an ompA genotype C. Chlamydial strains with this ompA genotype cause trachoma and have never previously been associated with urogenital infection. This result supported cessation of child protection investigations.Tracheoarterial fistula is a complication of tracheostomy with a high associated mortality. A 25-year-old male patient with Duchenne's muscular dystrophy underwent a percutaneous tracheostomy using the single tapered dilator (Blue Rhino) technique to facilitate weaning from mechanical ventilation. Nine weeks after the procedure, he developed significant upper airway bleeding, leading to haemodynamic instability. A CT angiogram of the neck and thorax did not reveal a source of the bleeding. The patient was subsequently transferred to the operating theatre where a 1 cm defect in the right common carotid artery was found and repaired with a graft from the left short saphenous vein. Clinicians who undertake tracheostomy formation should be aware of the possibility of tracheoarterial defect and may wish to discuss it at tracheostomy formation. It should be considered early in the event of a significant bleed. This case identifies deep tissue infection and misplacement of the tracheostomy tube as major contributing factors to fistula formation.Meckel's diverticulum is the most common intestinal congenital defect, its prevalence is 0.2%-4.0% and it occurs more commonly in children younger than 2-year old with intestinal bleeding and abdominal pain. Perforation in the elderly is very rare with no more than 35 articles reported worldwide. Here we report the case of a 62-year-old man who was admitted to hospital with a history of acute abdominal pain with a 20-day onset. The patient was treated with laparotomy and 30 cm ileal resection was performed for an 8×5 cm perforated ileum tumour at 50 from ileocecal valve with a side-to-side mechanical anastomosis for reconstruction. Having morbidity Clavien-Dindo scale I in postsurgical and good outcome in 6-month follow-up. Meckel's diverticulum is an infrequent pathology in paediatric and even rarer in adult population, however, it is always important to keep in mind how to act when is seen either as a finding or as a complication.Renal vein thrombosis is a rare, but potentially serious complication in patients with renal transplantation as it can lead to non-reversible graft injury and failure. Often this clinical entity is found in the early transplantation period, and the available management strategies are associated with favourable patient outcomes. The incidence, pathophysiology and outcomes for the delayed occurrence of renal vein thrombosis are unknown. The case here describes a unique situation with an excellent clinical outcome related to early diagnosis and appropriate care.Lower lumbar paraspinal muscles constitute a compartment as they are surrounded by distinct fascial and bony boundaries. Lumbar paraspinal compartment syndrome is a rare entity, often caused by intense exercise, but also can be a postoperative complication. We present a 60-year-old man with low back pain, numbness in the left lower back and radicular pain in the left lower extremity, which started after a surgery that involved prolonged positioning on the left side 7 years before, and persisted to the day of evaluation. There was an immediate transient rise in the creatine kinase after surgery. SGI-110 Electromyography showed a left lower lumbar-sacral plexopathy and a lumbar spine MRI revealed fatty infiltration of the lower lumbar-sacral paraspinal muscles. The emergence of radicular lower limb pain was likely due to the compression of the proximal portion of lumbar-sacral plexus during the acute stage of rhabdomyolysis.Sporadic Creutzfeldt-Jakob disease (sCJD) is a rare, fatal, neurodegenerative disease caused by accumulation of abnormally folded prion protein. sCJD can have a long asymptomatic incubation period, with little known about this period. We describe the first-ever participant within the population-based Rotterdam Study diagnosed with sCJD. We retrieved clinical data from both the population-based Rotterdam Study and the National Prion Disease Registry. In 2011, a female participant of the Rotterdam Study was diagnosed with probable sCJD and registered into the Registry. Four months earlier, she was classified as having mild cognitive impairment based on assessment in the Rotterdam Study. Clinical deterioration was rapid, with the patient dying 7 months after the research centre visit. Postmortem brain autopsy confirmed the diagnosis of sCJD. In conclusion, we describe the first case diagnosed with sCJD who during diagnostic workup for sCJD was classified as having mild cognitive impairment in a population-based cohort study.
