Acute interstitial nephritis is an uncommon but classic complication of minocycline therapy for acne. A 14-year-old African American girl was started on oral minocycline for the treatment of acne 6 weeks before presentation. After 4 weeks on minocycline, she developed a generalized rash, anasarca, fever, myalgia, nausea, vomiting, sore throat, and generalized body weakness. The evaluation showed increased levels of serum creatinine, urea nitrogen, and serum alanine and aspartate aminotransferases. Renal ultrasonography showed bilateral enlarged, echogenic kidneys, and percutaneous renal biopsy showed features of acute allergic interstitial nephritis. Treatment included methylprednisolone and intravenous fluids and discontinuation of minocycline. The elevated serum creatinine level (12.9 mg/dL (reference, 0.40-0.70 mg/dL)) suggests marked renal impairment corresponding with Kidney Disease Improving Global Outcomes acute kidney injury classification stage 3. The kidney injury improved from stage 3 to stage 1 within 3 days, and early treatment with steroids might have prevented chronic renal failure. The creatinine level promptly decreased to normal, and liver enzyme results also improved. In summary, the diagnosis of acute interstitial nephritis should be considered in patients who present with renal failure associated with recent use of minocycline, and treatment with corticosteroids should be considered early during the hospitalization.The current standard of care for the treatment of flow-limiting calcific iliac artery disease is balloon angioplasty and subsequent stent placement. However, the presence of calcified lesions may prevent adequate stent expansion or impede the delivery of large bore devices, such as those for transcatheter aortic valve replacement or endovascular aneurysm repair implants. Plaque modification through vessel preparation with orbital atherectomy may enable stent expansion and subsequent proper large device delivery with low rates of procedural complications. A retrospective, single center, case series of 13 subjects treated with orbital atherectomy in iliac arteries to enable large bore device delivery was conducted. Patients were selected for treatment based on iliac artery disease or inability to deliver devices. The procedural complication rate was defined as the composite of flow-limiting dissection, perforation, slow flow, vessel closure, spasm, embolism, and thrombosis. https://www.selleckchem.com/products/pt2399.html Technical success was assessed as angiographic luminal gain and subsequent successful delivery of large bore devices through the treatment area, as well as freedom from procedural complications. Orbital atherectomy vessel preparation of severely calcified iliac artery lesions resulted in adequate stent expansion safely and enabled delivery of rigid/large profile devices. Further studies are warranted to evaluate patient selection criteria, as well as long-term efficacy and safety rates of orbital atherectomy in the iliac artery. A wide range of duration of viral RNA shedding in patients infected with Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) has been observed. We aimed to investigate factors associated with prolonged and intermittent viral RNA shedding in a retrospective cohort of symptomatic COVID-19 patients. Demographic, clinical and laboratory data from hospitalised COVID-19 patients from a single centre with two consecutive negative respiratory reverse transcription-polymerase chain reaction (RT-PCR) results were extracted from electronic medical records. Kaplan-Meier survival curve analysis was used to assess the effect of clinical characteristics on the duration and pattern of shedding. Plasma levels of immune mediators were measured using Luminex multiplex microbead-based immunoassay. There were 201 symptomatic patients included. Median age was 49years (interquartile range 16-61), and 52.2% were male. Median RNA shedding was 14days (IQR 9-18). Intermittent shedding was observed in 77 (38.3%). We did not identify any factor associated with prolonged or intermittent viral RNA shedding. Duration of shedding was inversely correlated with plasma levels of T-cell cytokines IL-1β and IL-17A at the initial phase of infection, and patients had lower levels of pro-inflammatory cytokines during intermittent shedding. Less active T-cell responses at the initial phase of infection were associated with prolonged viral RNA shedding, suggesting that early immune responses are beneficial to control viral load and prevent viral RNA shedding. Intermittent shedding is common and may explain re-detection of viral RNA in recovered patients.

In the past 10 years, there has been a dramatic increase in our understanding of the immune system and how it contributes to fibrogenic processes within the lung. This review will compare some of the models used to investigate the pathogenesis and treatment of pulmonary fibrosis, in particular those used to study immune cell pathogenicity in idiopathic pulmonary fibrosis, highlighting their advantages and disadvantages in dissecting human disease.The growing 'Africans in China' literature has documented the extent and extensiveness of flows from Africa to Chinese cities. However, return migration has not received much attention, and even less is known about the role of the family in return consideration. The article focuses on how married Nigerians reckon return and family in Guangzhou city using data from ethnographic observations and interviews with 25 participants. While the family is central to how married migrants think about return, the dynamics vary among the participants. Migrants whose spouses/children reside in Nigeria complain about being distant from their families and the challenge of unification and 'absentee fatherhood'. Nigerian couples that live in Guangzhou as a family consider the high cost of raising children and the future competitiveness of their children as 'China-educated' as factors in return calculations. Moreover, despite living with their husbands in China, some Nigerian women desire to return to Nigeria to improve their lives, but they did not embark on a return journey to avoid family separation.
