Disseminated cryptococcosis in a patient with idiopathic CD4 + T lymphocytopenia presenting as prostate and adrenal nodules: diagnosis from pathology and mNGS, a case report.

Disseminated Cryptococcosis infection typically occurs in immunocompromised patients, often manifested as pneumonia or meningoencephalitis. Cases with involvement of either prostate or adrenal glands are less frequent. We describe a case of an immunocompromised 62-year-old man with new-found Idiopathic CD4 + T lymphocytopenia who presented with urinary irritation symptoms followed by headache. The patient was finally diagnosed as disseminated cryptococcosis of prostate, adrenal gland involvement with the help of combining histopathology of formalin-fixed, paraffin-embedded tissue with metagenomic next-generation sequencing technique to identify C neoformans sensu stricto in prostate, adrenal gland tissues. Clinicians should be aware of atypical presentations of cryptococcal disease. In this case of cryptococcosis in immunocompromised patients, we find that cryptococcosis can affect varied organs simultaneously and should be considered in the differential of infectious diseases. And mNGS technology helps to confirm the diagnosis.

Pathogenic mechanism and clinical diagnosis of hereditary abnormal copper metabolism / 临床肝胆病杂志

Copper is an important trace element in the human body, and copper deficiency or overload can lead to a series of body dysfunctions. This review focuses on hepatolenticular degeneration and related diseases of abnormal copper metabolism. Hepatolenticular degeneration has various clinical phenotypes, and related diseases, such as cholestatic liver disease, hereditary ceruloplasmin deficiency, and congenital abnormal glycosylation, may bring confusion to the clinical diagnosis of hepatolenticular degeneration. With reference to the latest research advances and experience in the diagnosis and treatment of hepatolenticular degeneration, this article discusses the pathogenic mechanism and clinical diagnosis of hereditary abnormal copper metabolism from the perspective of liver diseases.

Clinical diagnosis of genetic liver disease / 中华肝脏病杂志

The clinical phenotype of genetic liver disease is significantly different. Although the incidence of disease is low, because of the wide spectrum of diseases, the overall affected population is not rare. Therefore, clinical concern is a matter of alarm. Additionally, these diseases rarity in clinical practice has covered the recognition, causing increased problem of clinical misdiagnosis. In accordance with the problems encountered in clinical practice of our hospital, we explore the clinical diagnosis of genetic liver disease.

The correlations of infection rates with the administration timing of prophylactic antibiotics after hip arthroplasty / 实用医学杂志

Objective To assess the effects of different administration timing of prophylactic antibiotics on infections after hip arthroplasty. Methods 535 patients having undergone arthroplasty were divided into two groups: the experiment group (n=273)and the control group (n=262): The former groupwere administered with antibiotics until 24 hours postoperatively and the latter until 72 hours postoperatively. The two groups were compared in terms of postoperative infection rate. Results The infection rates in the experimental groupand the control group were 4.396%and 3..817%, with insignificant differencebetween them. Conclusion For those patients undergoing hip arthroplasty, extended administration of antibiotics after operation (over 48 hours) may not reduce the risk of recent the infection rate.
