RESUMO
Tinea capitis is a contagious dermatophyte infection of scalp and associated hairs. On the other hand, asymptomatic carriage is a status of positive dermatophyte scalp culture, but without signs or symptoms of tinea capitis, and no evidence of hair shaft invasion confirmed by direct microscopy. Tinea capitis and asymptomatic carriage mostly occur in children, but adult females are becoming another population in recent decades. In this study, we focused on the prevalence and related fungi of tinea capitis and asymptomatic carriage in elderly by the shampoo brush method, as well as the source of transmission, in 10 nursing home residents. Two hundred and thirteen residents were screened, and 186 isolates were identified, of which only three were dermatophytes (1.4%). The scalp dermatophyte isolates were identified as Trichophyton rubrum by morphological characters and sequences comparisons in all three cases. After revisiting, these cases were proved to be asymptomatic carriers by negative microscopic and culture examination; however, two cases were found to have concurrent tinea pedis and onychomycosis, which were identified as T. rubrum and Trichophyton interdigitale. The source of the T. rubrum scalp carriage may come from tinea elsewhere on the body of the same subject or from other people in the same institute. Finding and treating the source of carriage, as well as treating scalp carriage patients according to the colony counts, may help prevent disease spreading.

BACKBROUD/PURPOSE: Microalbuminuria and macroalbuminuria are markers of diabetic nephropathy (DN). The purpose of this study was to unravel the risk factors for DN in the young patients with type 1 diabetes (T1D). METHODS: 341 patients (160 males) with T1D diagnosed at the age 7.6 ± 4.0 years with disease duration 11.5 ± 6.5 years were assessed. Among them, 185 were young adults (aged 18.0-36.2 years). Urinary albumin creatinine ratio (UACR) was checked on morning spot urine. Microalbuminuria and macroalbuminuria were defined as a UACR of 30-300 mg/g and >300 mg/g, respectively, in at least 2 consecutive specimens. RESULTS: 50 (14.7%) patients were classified as microalbuminuria and 13 (3.8%) as macroalbuminuria. In all patients, multivariate logistic regression revealed that the most significant risk factors were average HbA1c (%), OR (95% CI) = 1.76 (1.37-2.25), P = 0.002); and male sex, OR = (odd ratio 2.31 (1.19-4.46), P = 0.013). In adult patients, the most significant factors were average HbA1c, OR = 1.74 (1.32-2.31), P = 0.003; and systolic blood pressure, OR = 1.06 (1.01-1.11), P = 0.011. Survival analysis showed average HbA1c levels significantly influenced the development of DN. CONCLUSION: The most important risk factors for DN were average HbA1c and age. When microalbuminuria is detected, proper treatment with ACEIs or ARBs and improving glycemic control can delay progression of DN.

Most yeasts causing infections in humans are part of commensal microflora and etiological agents of different infections when hosts become susceptible, usually due to becoming immunocompromised. The colonization of potentially pathogenic microbes in the oral cavity is increased by poor oral hygiene. This follow-up survey was conducted approximately two months after providing information on proper oral care at 10 nursing homes in Taiwan. Among the 117 of 165 residents colonized by yeasts, 67 were colonized by more than one yeast species. A total of 231 isolates comprising eight fungal genera and 25 species were identified. Candida albicans (44.6%) was the dominant species, followed by Candida glabrata (17.7%), Candida parapsilosis (8.7%), Candida tropicalis (7.8%), and Candida pararugosa (7.3%). Residents having a yeast colony-forming unit >10 (OR, 8.897; 95% CI 2.972−26.634; p < 0.001) or using a wheelchair (OR, 4.682; 95% CI 1.599−13.705; p = 0.005) were more likely to be colonized by multiple species. By comparing before and after oral-care education, dry mouth (OR, 3.199; 95% CI 1.448−7.068; p = 0.011) and having heart disease (OR, 2.681; 95% CI 1.068−6.732; p = 0.036) emerged as two independent risk factors for increased density of colonizing yeast.
RESUMO
Diabetic ketoacidosis (DKA) is associated with dehydration and which can cause acute kidney injury (AKI). The proportion of AKI in children and adolescents with DKA has not been reported in East Asian population. This study aimed to identify the prevalence of AKI and to determine whether there is an association between AKI severity and recovery time from metabolic acidosis in children and adolescents with DKA. Medical records of children and adolescents (aged <18 years) presenting with type 1 or type 2 diabetes mellitus and DKA between 2000-2017 at the MacKay Children's Hospital were retrospectively reviewed. AKI was defined by an admission creatinine level >1.5 times the calculated expected baseline creatinine level. Patients were divided into three groups based on AKI severity: no AKI, mild AKI, and severe AKI. In total, 170 (56.5%) patients with DKA presented AKI (mild AKI, 116 [38.5%]; severe AKI, 54 [18.0%]). Heart rate and laboratory parameters related to dehydration, such as corrected sodium level and blood urea nitrogen, were strongly associated with AKI development (P<0.01). Blood pH, plasma glucose, and potassium levels were also associated with AKI. A negative correlation with borderline significance between the estimated glomerular filtration rate (eGFR) and recovery time from metabolic acidosis was observed in the severe AKI group. AKI was highly prevalent in children and adolescents with DKA. An association between AKI and biomarkers indicating dehydration was noted. The recovery time from metabolic acidosis following treatment may be longer in children with a decreased eGFR who present with severe AKI. AKI is a common complication in children with DKA.

BACKGROUND: Graves disease (GD) is the most common cause of thyrotoxicosis in children and adolescents, accounting for 15% of all thyroid diseases during childhood. Anti-thyroid drugs (ATD) are recommended as the first-line treatment in children and adolescents. However, the remission rate is lower in children than in adults, and the optimal treatment duration and favorable factors associated with remission remain unknown. We aimed to investigate long-term outcomes of pediatric GD patients receiving ATD. METHODS: We retrospectively reviewed medical charts of 396 GD subjects from 1985 to 2017 at MacKay Children's Hospital. Ninety-six patients were excluded from the analyses, including 71 patients followed for less than one year, 6 patients who received radioactive therapy and 19 patients who received surgery. The remaining 300 patients initially treated with ATD and followed up for more than 1 year constituted our study population. RESULTS: The 300 patients comprised 257 (85.7%) females and 43 (14.3%) males. Their median age at diagnosis was 11.6 (range 2.7-17.8) years with 11 patients (3.7%) younger than 5 years. Their median follow-up period was 4.7 (range 1.1-23.9) years. Overall, 122 patients achieved the criteria for discontinuing ATD treatment, and seventy-nine (39.9%) patients achieved remission, with a median follow-up period of 5.3 (range 1.5-20.1) years. Patients in the remission group were more likely to be aged <5 years (remission vs. relapse vs. ongoing ATD; 11.4 vs. 0 vs. 2.6%, P = 0.02), less likely to have a family history of thyroid disease (24.1 vs. 42.1 vs. 52.6%, P = 0.001), and had lower TSH receptor antibody (TRAb) levels (42.8 vs. 53.6 vs. 65.1%, P = 0.02) at the time of diagnosis. CONCLUSION: Long-term ATD remains an effective treatment option for GD in children. Pediatric GD patients aged <5 years, having no family history of thyroid disease and having initial lower TRAb levels were more likely to achieve remission.
