Quantitative measurement of BK virus DNA (Q-BKDNA) has been used for the early diagnosis and monitoring of BK virus-associated nephropathy (BKVAN). This study was designed to determine the BKDNA cutoff for the diagnosis of BKVAN. Between June 2005 and February 2007, 64 renal transplant recipients taken renal biopsies due to renal impairment submitted plasma and urine for Q-BKDNA. Eight BKVAN patients (12.5%) had median viral loads of 6.0 log(10) copies/mL in plasma and 7.3 log(10) copies/mL in urine. Among 56 non-BKVAN patients, 45 were negative for Q-BKDNA; 4 were positive in plasma with a median viral load of 4.8 log(10) copies/ mL, and 10 were positive in urine with a median viral load of 4.8 log(10) copies/mL. Receiver operating characteristic curve analysis showed that a cutoff of 4.5 log(10) copies/mL in plasma and a cutoff of 5.9 log(10) copies/mL in urine had a sensitivity of 100% and a specificity of 96.4%, respectively. A combined cutoffs of 4 log(10) copies/ mL in plasma and 6 log(10) copies/mL in urine had better performance with a sensitivity of 100% and a specificity of 98.2% than each cutoff of urine or plasma. QBKDNA with the combined cutoffs could reliably diagnose BKVAN in renal transplant recipients.

BACKGROUND: Direct antigen test (DAT) and culture are primary tests to diagnose infections by respiratory viruses, but are mainly available for the traditional viral pathogens such as respiratory syncytial virus (RSV), influenza virus, parainfluenza virus (PIV), and adenovirus in clinical laboratories. The objective of this study was to evaluate a multiplex reverse transcriptase-PCR method using Seeplex(TM) RV Detection kit (Seegene, Korea) for the detection of rhinovirus, coronavirus, and human metapneumovirus (hMPV). METHODS: From January to May 2007, nasopharyngeal aspirates (NPAs) from pediatric patients negative for culture and DAT of traditional viral pathogens were tested with Seeplex(TM). All the amplicons were directly sequenced and homology of the sequences was searched in the National Center for Biotechnology Information (NCBI) database. Patients' medical records were reviewed for clinical and demographic features. RESULTS: Forty-seven (26.4%) of 178 NPAs were positive: 18 rhinovirus, 15 hMPV, 4 RSV A, 3 coronavirus OC43, 3 influenza virus A, 2 adenovirus, 1 coronavirus NL63, and 1 RSV B. Based on maximum identity, each of the sequences indicating rhinovirus, hMPV, and coronavirus OC43 matched to the corresponding viruses with homology of 94-98%, 96-99%, and 98-100%, respectively. Seeplex(TM) positive patients were 0-11 yr old with a male:female ratio of 1.5:1. Clinical diagnoses included 9 pneumonia, 6 bronchiolitis, 2 cold, 1 asthma exacerbation for rhinovirus; 10 pneumonia, 4 bronchiolitis, and 1 clinical sepsis for hPMV; and 1 pneumonia, 2 croup, and 1 cold for coronavirus. CONCLUSIONS: Multiplex reverse transcriptase-PCR method using Seeplex(TM) RV Detection kit is a reliable test to detect rhinovirus, hMPV, and coronavirus. It may improve the diagnostic sensitivity for RSV, influenza virus, PIV, and adenovirus.

Background:
While many studies have investigated the epidemiology and clinical features of female pattern hair loss (FPHL), few of these are long-term studies.
Objective:
This study evaluated and compared a large cohort of long-term FPHL patients to short-term FPHL patients from other studies.
Methods:
A retrospective chart review was conducted at the Alopecia Clinic of the Department of Dermatology in Myongji Hospital of 982 FPHL patients during a 10-year period from March 2007 to February 2017.
Results:
The 3,549 alopecia patients included 2,342 (66.0%) with androgenetic alopecia (AGA) patients; among them, 982 (27.7%) had FPHL. Patients in their 30s (24.6%) were the most affected group of FPHL patients, followed by those in their 20s (21.7%), 40s (20.3%), 50s (13.8%), and teenagers (9.2%). The FPHL patients included 301 (30.5%) with a paternal familial predisposition, 136 (13.7%) with a maternal familial predisposition, and 70 (7.0%) with both familial predispositions. The FPHL patients were classified according to the Ludwig classification as type 1 (62.7%), type 2 (33.2%), or type 3 (3.9%). Abnormalities in serum total cholesterol levels and triglyceride levels were observed in 70 (14.3%) of 488 patients, and in 49 (21.2%) of 231 patients, respectively. The most common comorbid conditions were seborrheic dermatitis, followed by hypertension, hyperlipidemia, thyroid diseases, diabetes mellitus, polycystic ovarian syndrome (PCOS), and anemia. When seborrheic dermatitis is excluded, thyroid diseases and PCOS were most common in patients in their 20s and 30s. Hypertension, hyperlipidemia, and diabetes mellitus were most common in patients in their 40s.
Conclusion
Compared to studies from 20∼30 years ago, the proportion of FPHL patients among total alopecia patients appeared to increase significantly. In addition, the proportion of teenage patients has also increased, likely due to early puberty.
