The results of this preliminary study suggest that PET is useful in the management of SCCC. PET could have more value in detecting occult metastases if future novel therapies are able to offer better control of extensive SCCC.

Many uncommon Candida spp. (species other than C. albicans, C. parapsilosis, C. glabrata, C. tropicalis, and C. krusei) have been shown to emerge in tertiary care facilities. We aimed to investigate these uncommon candidemia in children. Forty-six cases of candidemia caused by uncommon Candida spp. were identified during 2003–2015 from a medical center in Taiwan. The most common specie was C. guilliermondii (31.2%), followed by C. lusitaniae (18.8%) and C. metapsilosis (18.8%). These cases were analyzed and compared with 148 episodes of C. albicans candidemia. The incidence density of uncommon Candida spp. candidemia and the proportion to all candidemia episodes increased substantively during the study period. Prior exposure to azoles was uncommon in the 30 days prior to infection, but fluconazole resistant strains were significantly more common (n = 19, 41.3%). The increased incidence density of uncommon Candida spp. candidemia was associated with increasing use of antifungal agents. No differences in demographics, underlying comorbidities, risk factors, clinical features, dissemination, and 30-day mortality were found between uncommon Candida spp. and C. albicans candidemia. Patients with uncommon Candida spp. candidemia were more likely to require modifications in antifungal treatment and receive echinocandin drugs (43.5% vs 21.6%, p = 0.007). Candidemia caused by uncommon Candida spp. had poorer response to antifungal treatment, led to longer duration of candidemia (median 4.0 versus 2.5 days, p = 0.008), and had a higher treatment failure rate (56.5% vs 38.5%, p = 0.040).

This study was designed to evaluate the learning curve of transvaginal natural orifice surgery (NOS) for adnexal tumors based on the type of procedure (adnexectomy or cystectomy). Design: Retrospective cohort study. Setting: Tertiary-care university hospital. Patients: One hundred thirty-six women with adnexal tumors. Interventions: A series of 136 consecutive transvaginal NOS for adnexal tumor were performed between April 2011 and June 2016. Eighty-five patients (62.5%) had undergone cystectomy, and 51 patients (37.5%) had undergone adnexectomy. Measurements and Main Results: The transvaginal NOS procedures included vaginal, endoscopic, single-port access techniques and were divided into 2 categories: adnexectomy and cystectomy. Operating time was electronically recorded and was defined as the time from the creation of a posterior colpotomy incision until the complete closure of the posterior colpotomy opening. The average operating time for the cystectomy and adnexectomy groups was 42.7 and 37.7 minutes, respectively (p = .015). The learning curve was analyzed using the cumulative summation method and showed that 36 cases were needed to achieve proficiency in transvaginal NOS for ovarian cystectomy. However, there was no significant cut-off point to determine the number of patients who had undergone adnexectomy. Conclusion: A well-trained gynecologic endoscopist can achieve surgical proficiency in transvaginal NOS cystectomy after 36 cases. It is suggested that the surgical transvaginal NOS procedure should begin with adnexectomy rather than with cystectomy to avoid initial technical challenges.

BackgroundOsteoporosis is a common comorbidity in non-cystic fibrosis (non-CF) bronchiectasis patients. We determined whether desaturation during 6-min walk test (6MWT) can be a predictor for osteoporosis risk.MethodsThis was a retrospective cross-sectional study. Sixty-six non-CF bronchiectasis patients were enrolled. Lung function, walking distance, the lowest oxygen saturation (SpO2), the fall in SpO2 (ΔSpO2), and the distance–saturation product (DSP) were determined during the 6MWT. Desaturators (n = 45) were defined as those with ΔSpO2 > 10% or the lowest SpO2 < 88%. Bone mineral density (BMD) was determined through dual-energy X-ray absorptiometry. The severity of non-CF bronchiectasis was evaluated using high-resolution computed tomography.ResultsOsteoporosis was evident in more desaturators (82%) than non-desaturators (43%, p < 0.01). BMD at the level of the femoral neck was significantly lower in desaturators than in non-desaturators (− 3.6 ± 1.1 vs. − 2.4 ± 0.9, p < 0.01). BMD was correlated positively with the lowest SpO2 and negatively with ΔSpO2 and severe exacerbations. In multivariate linear regression analysis, desaturation during 6MWT was the most significant predictive factor for osteoporosis (95% confidence interval − 1.60 to − 0.26, p = 0.01). Other risk factors included old age, low body mass index and severe exacerbation.ConclusionsExertional desaturation during the 6MWT was a significant predictive factor for osteoporosis in Asian non-CF bronchiectasis patients. The 6MWT may be useful in identifying the osteoporotic phenotype of non-CF bronchiectasis and increasing clinician awareness to promote early intervention.
