ChAdOx1 nCOV19 vaccineinduced resistant thrombotic thrombocytopenia and cerebral venous nasal thrombosis CVST

A 19-year-old man presented with acute severe ulcerative colitis. He was taking azathioprine (therapeutic metabolites) and sulphasalazine as well as infliximab with a therapeutic drug level. On day 3 of hydrocortisone therapy, he met day Oxford criteria with >8 bloody stools per day and was given faecal microbiota transplantation and subsequently commenced on dietary therapy combining several strategies-(1) increased intake of fermentable fibres, (2) reduced intake of overall and sulfur-containing protein and (3) restriction of sulfate and sulfite food additives. At week 8 assessment, he was in clinical and endoscopic remission and remained in clinical and endoscopic remission at 12 months.Histoplasmosis is a systemic fungal infection caused by Histoplasma capsulatum, a dimorphic fungus that spreads commonly by contamination of soil with bird and bat droppings. The infection remains latent in most patients until manifested by reduced immune status, for example, HIV/AIDS, corticosteroid/immunosuppressive therapy or in solid organ transplant recipients. Tuberculosis and histoplasmosis may cooccur rarely in HIV and the clinical resemblance of both diseases may hinder identification of patients' harbouring dual infection, especially in regions non-endemic for histoplasmosis. We report a case of disseminated histoplasmosis with disseminated tuberculosis in an incidentally detected patient with HIV-positive who presented with reports of fever and skin rash for 10 days. The Mantoux positivity and CT of chest and abdomen revealing multiple necrotic lymph nodes coupled with bone marrow and skin biopsy divulging histoplasmosis and tuberculosis helped us clinch the concurrent infection.The use of implants has enabled more treatment options for prosthetic rehabilitation of partially and completely edentulous patients. This clinical report describes a treatment approach for an 80-year-old patient taking advantage of the remaining natural teeth for prosthetic rehabilitation. The final treatment plan included natural tooth-supported and implant-supported crowns combined with a milled bar partial overdenture retained by tilted dental implants. The overdentures supported by the milled bar implants provide the advantages of both fixed and removable restorations. In addition to patient satisfaction, the overdentures also minimise alveolar bone resorption, increase longevity and stability and improve masticatory efficiency.Quinidine is one of the oldest antiarrhythmics known. Over the years, its use has decreased along with its side effects. Our case describes a 69-year-old woman with recurrent resistant ventricular tachycardia on Quinidine and Amiodarone who presented with acute liver toxicity. Drug-induced liver toxicity was at the top of our differential diagnosis list. Taking multiple factors into consideration, a decision was made to discontinue Quinidine, the patient's symptoms and lab abnormalities resolved within 1 week, yielding the diagnosis of Quinidine hypersensitivity.We present a case of sudden asystole that was elicited via the trigeminocardiac reflex in a patient undergoing surgery for a frontal sinus fracture. Asystole occurred after mild stimulation of the supraorbital nerve during dissection along the superior orbital rim. Anticholinergics were administered and lidocaine-soaked gauze was applied to the exposed wound. The patient was an athlete and had pre-existing sinus bradycardia. We hypothesise that the severe reflex response was associated with his underlying increased vagal tone. When performing surgery in patients with increased vagal tone, preventative measures to diminish the trigeminocardiac reflex are recommended. Further studies are needed.Methaemoglobinaemia is a rare disease that is typically caused by a medication or other exogenous agent, with dapsone being the most common. It occurs when the concentration of methaemoglobin rises via ferrous haeme irons becoming oxidised to the ferric state, which shifts the oxygen dissociation curve to the left. The net result of an elevated methaemoglobin concentration is functional anaemia and impaired oxygen delivery to tissues. At lower blood levels, this can cause symptoms such as cyanosis, lethargy, headache and fatigue, whereas at higher levels it can be fatal. Here we discuss a subtle case of dapsone-induced methaemoglobinaemia presenting as subacute mental status changes and apparent hypoxia, thus highlighting the association between methaemoglobinaemia and dapsone. This case demonstrates the importance of thorough medication reconciliation and maintaining a broad differential diagnosis, while also recognising the significance of conflicting data and their implications for the workup.Certain medications have been implicated in causing acute myocardial infarctions (AMI). Sumatriptan, a medication usually prescribed for acute migraine and cluster headaches has been documented as potentially causing coronary vasospasm, thereby leading to MI. This is usually seen in patients with strong risk factors for coronary artery disease (CAD) or in those with established CAD. Most cases thus far have been reported in patients using the subcutaneous preparation of sumatriptan. Here, we present a case of a patient without prior risk factors for CAD and angiographically unremarkable coronary arteries who presented with evidence of an AMI after oral sumatriptan use for migraines.Transverse vaginal septum is one of the variants of Mullerian duct anomaly, caused as a result of defective fusion or recanalisation of vaginal and Mullerian organs. At an early age, it commonly presents as primary amenorrhea along with cyclical abdominal pain while later on usually it presents as dyspareunia and infertility. VT104 Our 22-year-old patient presented with secondary amenorrhea. It is very unusual for a transverse vaginal septum to cause secondary amenorrhea. MRI and clinical examination raised the suspicion of transverse vaginal septum causing secondary amenorrhea. She attained regular menstrual cycle after septum excision. The proposed theory behind it is obliteration of microperforated transverse vaginal septum because of menstrual blood and cell debris. Thus, a rare possibility of transverse vaginal septum should also be considered as a differential diagnosis of secondary amenorrhea.
