We describe the clinical and demographic characteristics, virological follow-up, and management of five confirmed monkeypox cases from New Delhi, India without any international travel history. The viral load kinetics and viral clearance were estimated in oropharyngeal swabs (OPS), nasopharyngeal swabs (NPS), EDTA blood, serum, urine, and various lesion specimens on every fourth day of follow-up ranging from 5 to 24 post onset day (POD) of illness. All five cases presented with mild to moderate-grade intermittent fever, myalgia, and lesions on the genitals, groins, lower limb, trunk, and upper limb. Four cases had non-tender firm lymphadenopathy. No secondary complications or sexually transmitted infections were recorded in these cases except for the presence of viral hepatitis B infection marker hepatitis B virus surface antigen (HBsAg) in one case. All the cases were mild and had a good recovery. A higher viral load was detected in lesion fluid (POD 9), followed by lesion roof (POD 9), urine (POD 5), lesion base (POD 5), and OPS/NPS (POD 5). The monkeypox virus (MPXV) DNA was detected in clinical samples from 5th to 24th POD. These monkeypox cases without international travel history suggest the underdiagnosed monkeypox infection in the community. This emphasizes the need for active surveillance of MPXV in the high-risk population such as men having sex with men and female sex workers. 相似文献

Four rare cases of plant thorn synovitis of left elbow were admitted at our institution, which were initially misdiagnosed as partially treated septic arthritis of elbow or Juvenile inflammatory arthritis. All of them were of paediatric age group. Symptoms included pain, swelling, and decreased range of motion of affected joint. On examination synovitis was present in all patients.Roentgenograms & Ultrasonography were inconclusive in all patients, Definitive diagnosis was made only after arthrotomy, Thorn fragments (Acacia arabica) were recovered from the hypertrophied synovium & subtotal synovectomy was done and sent for histopathological examination. All patients improved after surgery with mean residual flexion deformity of 12.5 ± 2.86°. Plant thorn induced synovitis of elbow is rare, it must be included in the differential diagnosis of monoarthritis of elbow and a high index of suspicion is needed for retained thorn fragments in elbow joint causing synovitis. Its optimal treatment is arthrotomy, foreign body removal and total/subtotal synovectomy. 相似文献

Quantitative proteomics, using LC-MS/MS, is increasingly used to quantify drug transporters present in tissues and cells. Most of these investigations quantify total transporter expression in the cells by utilizing a total membrane fraction, not only the plasma membrane. Here, we report development and optimization of a biotinylation method to quantify protein expression of transporters in the plasma membrane of cells. The Pierce cell surface isolation protocol was optimized for plasma membrane isolation. Incubation of OATP1B1-expressing CHO cells with 0.78 mg/mL of membrane impermeable biotinylation reagent (sulfo-NHS-SS-biotin) at 37°C for 1 h resulted in optimum isolation of the plasma membrane. Subsequently, the expression of transporters in the plasma membrane as a percent of the total was determined by quantitative proteomics using LC-MS/MS. Mean (±SD) plasma membrane expression of OATP1B1 in plated OATP1B1-expressing CHO, MDCKII, and HEK293 cells was found to be 79.7% (±4.7%), 67.7% (±12.2%), and 65.3% (±6.8%) of total cell OATP1B1 expression. Mean (±SD) plasma membrane expression of OATP1B3 in plated OATP1B3-expressing HEK293 cells, OATP2B1 in plated OATP2B1-expressing MDCKII cells, and sodium/taurocholate co-transporting polypeptide (NTCP) in plated NTCP-expressing CHO cells was 63.2% (±1.6%), 37.1% (±15.7%), and 71.7% (±1.2%), respectively. This method of quantifying transporter protein expression in the plasma membrane will be useful in the future to predict transporter-mediated drug disposition. 相似文献

Chronic paronychia is an inflammatory disorder of the nail folds of a toe or finger presenting as redness, tenderness, and swelling. It is recalcitrant dermatoses seen commonly in housewives and housemaids. It is a multifactorial inflammatory reaction of the proximal nail fold to irritants and allergens. Repeated bouts of inflammation lead to fibrosis of proximal nail fold with poor generation of cuticle, which in turn exposes the nail further to irritants and allergens. Thus, general preventive measures form cornerstone of the therapy. Though previously anti-fungals were the mainstay of therapy, topical steroid creams have been found to be more effective in the treatment of chronic paronychia. In recalcitrant cases, surgical treatment may be resorted to, which includes en bloc excision of the proximal nail fold or an eponychial marsupialization, with or without nail plate removal. Newer therapies and surgical modalities are being employed in the management of chronic paronychia. In this overview, we review recent epidemiological studies, present current thinking on the pathophysiology leading to chronic paronychia, discuss the challenges chronic paronychia presents, and recommend a commonsense approach to management. 相似文献
