There have been anecdotal reports that local hyperthermia was effective in the treatment of viral warts. We conducted a randomized, patient-blinded, placebo-controlled trial to test the effect of local hyperthermia (44 degrees C for 30 min a day for 3 consecutive days plus 2 additional days 2 weeks later) on plantar warts. By the end of 3 months, 53.57% of patients (15/28) in the treatment group and 11.54% of patients (3/26) in the control group were cured (P < .01). The effect was not influenced by patient age, duration of disease, or number or size of lesions.

We employed a nested PCR assay to detect Sporothrix schenckii DNA of 38 strains (including all the 24 mtDNA types) collected from different areas of the world, in tissue of eight mice infected with ATCC10268 strain of the fungus, and the skin biopsies of nine patients with sporotrichosis. In addition, the same procedures were used with two strains of Ceratocystis minor and isolates of 10 species of other pathogenic fungi. The outer primers SS(1) and SS(2) and inner primers SS(3) and SS(4) of the 18S rRNA gene of S. schenckii were employed. A 152 bp fragment was detected in all 38 strains of S. schenckii, eight animal specimens and nine human skin biopsies, but not samples of C. minor and the other fungal species. The detection limit of 50 fg of S. schenckii DNA extract was determined with ethidium bromide staining. In summary, we demonstrated that nested PCR assay could identify S. schenckii of all the mtDNA types and in isolates recovered from different areas of the world. The nested PCR assay seems to be highly sensitive and specific and provides a rapid method for diagnosis of sporotrichosis under conditions of contamination avoidance.

Background:The impact of high body mass index (BMI, >23/25 kg/m2) on surgical outcomes and prognosis in patients with esophageal carcinoma (EC) after undergoing esophagectomy remains controversial. We herein conducted a systematic review and meta-analysis to determine the relationship between high BMI and surgical outcomes and prognosis in patients undergoing esophagectomy for EC.Methods:The study search was conducted by retrieving publications from the PubMed, Embase, Web of Science, and CNKI (up to September 8, 2017). Nineteen studies with 13,756 patients were included in this meta-analysis.Results:We found that high BMI was closely associated with a higher incidence of wound infection (odds ratio [OR]: 1.41, 95% confidence interval [CI]: 1.02–1.97, P = .04), cardiovascular complications (OR: 2.51, 95% CI, 1.65–3.81, P < .0001), and anastomotic leakage (OR: 1.50, 95% CI, 1.21–1.84, P = .0002), but a lower incidence of chylous leakage (OR: 0.59, 95% CI, 0.40–0.88, P = .01) when compared with normal BMI. The high BMI group was not associated with better or worse overall survival (OS) (hazard ratio [HR]: 0.95, 95% CI, 0.85–1.07, P = .4) and disease-free survival (HR: 0.95, 95% CI, 0.72–1.25, P = .72) than the normal BMI group. However, in the subgroup analysis, the pooled result of HRs generated from multivariate analyses suggested that high BMI could improve OS in EC patients (HR: 0.84, 95% CI, 0.76–0.93, P < .01).Conclusions:Overweight patients with EC should not be denied surgical treatment, but intraoperative prevention and careful postoperative monitoring for several surgical complications must be stressed for this population. Besides, high BMI might be a prognostic predictor in EC patients; further studies are warranted.
