Semin Thromb Hemost DOI: 10.1055/s-0040-1702918This is a review of the evidence for the use of different platelet count thresholds prior to invasive procedures and surgery. This review will focus on three procedures that are common in patients with thrombocytopenia—central venous catheter insertion, liver biopsy, and lumbar punctures and epidural catheters—as well as highlighting the lack of evidence for more major surgery. Tunneled or untunneled central venous catheters are low-risk procedures and can be safely performed without any intervention when the platelet count is 20 × 109/L or abov...

ConclusionsCryptococcosis develops in various organs. Typical radiological manifestation accompanied with positive serum CrAg provides helpful clues for the diagnosis. Lumbar puncture is a critical diagnostic method to distinguish CM. The accumulated dose of GC is associated with cryptococcosis in patients with CTD.Key Points•Pulmonary cryptococcosis is suspected if pulmonary nodules adjacent to the pleura are present, with serum CrAg positive.•Cryptococcal meningitis has insidious onset and the diagnosis mainly depends on lumber puncture.•Cryptococcal sepsis is not rare and needs timely blood culture in suspected patients.

Authors: Headman ZC, Matson MC, Schneider RP, Potter JL, Loguda-Summers DL, Bhatia S, Kondrashova T Abstract Context: Various forms of simulation-based training, including training models, increase training opportunities and help assess performance of a task. However, commercial training models for lumbar puncture and epidural procedures are costly. Objective: To assess medical students' and residents' perception of 3-dimensional (3D)-printed lumbar, cervical, and pelvic models for mastering joint injection techniques and to determine the utility of ultrasonography-guided needle procedure training. Methods:...

Abstract BACKGROUND/AIMS: In the era of increasing incidence of syphilis globally, ocular syphilis is re-emerging as an important cause of uveitis. The aim of this study was to determine the clinical and laboratory characteristics of ocular- and neurosyphilis among individuals with and without HIV infection. METHODS: Retrospective analysis of patients diagnosed with ocular syphilis presenting to Tygerberg Hospital, South Africa, over a 5-year period ending December 2018. RESULTS: Two-hundred and fifteen eyes of 146 patients were included. HIV coinfection was present in 52.1% of the patients, with 23.7% o...

AbstractPurpose of ReviewThe goal of this review is to describe the presenting features of fulminant idiopathic intracranial hypertension (IIH) and outline the multimodal approach to its treatment.Recent FindingsVenous sinus stenting may be an appropriate alternative to optic nerve sheath fenestration or cerebrospinal fluid shunting in select patients with fulminant IIH. Prompt surgical intervention maximizes the chance of visual recovery in patients with fulminant IIH.Summary“Fulminant IIH” is defined as intracranial hypertension with no secondary cause, severe vision loss within 4 weeks of symptom onset,...

Authors: Sun JM, Wang C, Jin DQ, Deng F Abstract Congenital tuberculosis (TB) is rare and the prognosis is poor if not detected early. The diagnosis is often delayed owing to non-specific clinical presentation, misdiagnosis and undiagnosed maternal TB during pregnancy. A 12-day-old girl presented with a 5-day history of fever, cough, poor feeding and respiratory distress. Her mother had a cough and fever at 30 weeks gestation which was managed empirically as community-acquired pneumonia without a TB workup. Immediately postpartum, her mother developed a high fever and shortness of breath and required admission...

A 45-year old HIV patient presented to the hospital with a 1-week history of holocranial headache. He was in regular use of antiretroviral therapy with a CD4 count of 1,128 cells/mm3. The patient complained of soft tissue mass on his frontoparietal region, which was noticed 6 months ago. He denied fever. Radiological examination suggested an osteosarcoma (Fig. 1). Biopsy of the lesion showed chronic granulomatous inflammation with areas of necrosis and fibrosis. Lumbar puncture revealed 13 leucocytes/ µl (87% lymphocytes), protein 93 mg/dl, glucose 53 mg/dl (serum glucose was 139 mg/dl), and VRDL 1:1 (serum 1:128).

Conclusion: Bariatric surgery appears to lead to considerable improvement in IIH. Idiopathic intracranial hypertension is not a well-publicized comorbidity of obesity, but its presence may be considered as an indication for bariatric surgery. PMID: 32195557 [PubMed - as supplied by publisher]
