The patient is a 33-year-old Iranian woman without a significant past medical history with the full range of narcolepsy symptoms that started within two weeks after her recovery from COVID-19. Sleep studies revealed increased sleep latency and three sleep-onset rapid eye movement events, compatible with a narcolepsy-cataplexy diagnosis.
A 64-year-old man presented with asymmetric paresthesia and subsequent weakness of his feet and a 10-kg weight loss over 40 days. Electrodiagnostic studies revealed distal axonal sensory-motor polyneuropathy with ongoing axonal loss. A peroneal nerve biopsy showed intravascular proliferation of CD-20 positive lymphocytes, which suggested intravascular large B-cell lymphoma.
A 30-year-old man presented with sudden chest pain and evidence of multiple cystic lesions in both long and left-sided pneumothorax in HRCT. H&E stained section and IHC for CD1a and S100 were positive in lung samples. The patient was treated with the diagnosis of Isolated pulmonary langerhans cell histiocytosis.
Papillary thyroid carcinoma of the pyramidal lobe is rare. We describe a case of a 77-year-old woman who corroborates current literature findings, namely greater presence of adverse prognostic factors. Upper Neck Papillary Thyroid Cancer is a new entity, proposed to group these tumors with potential clinical and therapeutic implications.
A 66-year-old breast ductal carcinoma patient developed obstructive jaundice, presenting with epigastric discomfort and dark-colored urine. Contrast-enhanced computed tomography and endoscopic retrograde cholangiopancreatography revealed bile duct stenosis. Brushing cytology and tissue biopsy confirmed bile duct metastasis, and a self-expandable metallic stent was placed/replaced endoscopically, extending the patient’s life.
It is difficult to anatomically understand the three-dimensional structure of the middle ear and temporal bone during surgery, and great surgical technique are required. Therefore, complications are avoided through simulation using a three-dimensional printer, which was effective in not only safe and reliable surgery but also educating young physicians.
Immunodeficient patients are less prone to develop serious complications of COVID-19 and cytokine storm. However, they are more likely to develop opportunistic infections that can mimic the symptoms of the SARS-CoV-2. we presented a 27-year-old male case of SARS-CoV-2, who was complicated with Pneumocystis jirovecii pneumonia, following treatment with rituximab.
A 7-year-old American short-haired cat was presented with blepharospasm in the right eye. The case was finally performed with orbital exenteration, leading to the diagnosis of feline restrictive orbital myofibroblastic sarcoma. Adjuvant chemotherapy with toceranib was given for one month after surgery. However, the case died four months after surgery.
Oral mucosal lesions may persist years before diagnosis of inflammatory bowel disease (IBD) and subsequent primary sclerosing cholangitis (PSC). It may be that a dental practitioner may be the first clinician to suspect IBD. Suspect IBD; early referral and close collaboration with a gastroenterologist are recommended.
Pseudo-infarction electrocardiographic changes associated with hypokalemia and hypocalcemia is rare. A 76-year-old lady with previous total thyroidectomy presented with unspecific symptoms. Electrocardiogram demonstrated ST-elevation. She was found to have hypokalemia and hypocalcemia associated with delayed onset hypoparathyroidism. This may suggest possible etiologies like coronary vasospasm and catecholamine-associated myocardial injury.
