Tape-stripping method in man: comparison of evaporimetric methods

BACKGROUND/PURPOSE: If the occlusion time of a closed chamber evaporimeter on the skin is too long, saturation might occur. We previously compared an open chamber and a closed chamber device on healthy volunteers. Comparable data on stripped skin with higher evaporation rates are not available. This study compares the sensitivity and correlation of open and closed chamber devices in a tape-stripping human model. The amount of tape removed SC was also quantified with a protein assay method. METHODS: Ten healthy volunteers (six male and four female; seven Caucasians and three Asian; mean age 38+/-16) were enrolled. In a randomized manner, one forearm was measured by an open chamber device and the opposite by a closed chamber device. After recording baseline measurements, 20 strippings were taken on each test site with tape disks. Transepidermal water loss (TEWL) was measured at the end of 10 and 20 tape strippings at each test site. Stratum corneum (SC) aggregates in the strips was assayed. RESULTS: The mean values obtained from two devices were similar after 10 trips and 20 strips. There was no statistically significant difference. The closed chamber device showed a slightly higher (but not significant) inter-individual coefficient of variation. SC aggregates in the strips were similar and without a statistically significant difference. CONCLUSION: The study suggests that both devices might yield similar TEWL values on stripped human skin in vivo.

Reporting and grading of complications after mid-urethral sling surgeries: Could the “Clavien-Dindo Classification” be adopted?

Background:To construct a modified model for reporting and grading of postoperative complications after the mid-urethral sling (MUS) procedure based on the Clavien-Dindo classification. In addition, complications of three different types of MUS were compared.Materials and methods:A PubMed search for postoperative complication after MUS was carried out for the period between January 1990 and July 2018. Reported complications were stratified in a plate form designed in accordance with grades of the Clavien-Dindo classification. Then, the proposed model was applied on reported complications in 160 females who underwent three different procedures of MUS (transvaginal tape [TVT], transobturator tape [TOT], and autologous fascial sling) with a minimum follow-up of 24 months.Results:The mean ± SD age at time of surgery was 46 ± 7 years. TVT was carried out in 75 (47%) patients, TOT in 40 (25%), and fascial sling in 45 (28%). The total number of complications was 62 in 43 (26.8%) patients. The vast majority of complications were Grade I and Grade II 19 (12%) and 21 (13%) out of 160 patients, respectively. Transient postoperative voiding difficulty (Grade II) and de novo urgency (Grade II) were the most prevalent complications in the fascial sling method (15.4% for each), whereas transient thigh pain (Grade II) was the most frequently reported complication after TOT (10%). Life-threatening vascular injury (Grade IV-a) was a serious complication in TVT cases.Conclusions:Postoperative complications of the MUS could be graded according to Clavien''s classification. The vast majority of complications were Graded I or II. TVT can cause serious life-threatening complications.     

Anti-inflammatory activity of hamamelis distillate applied topically to the skin

Summary The anti-inflammatory activity of hamamelis distillate has been evaluated with respect to drug concentration (0.64 mg/2.56 mg hamamelis ketone/100 g) and the effect of the vehicle (O/W emulsion with/without phosphatidylcholine (PC) in an experimental study. The effects were compared with those of chamomile cream, hydrocortisone 1% cream and 4 base preparations. Erythema was induced by UV irradiation and cellophane tape stripping of the horny layer in 24 healthy subjects per test. Skin blanching was quantified by visual scoring and chromametry. Drug effects were compared with one another and with an untreated control area, as well as with any action due to the vehicle.UV-induced erythema at 24 h was suppressed by low dose hamamelis PC-cream and hydrocortisone cream. Hydrocortisone appeared superior to both hamamelis vehicles, hamamelis cream (without PC) and chamomile cream. The latter preparation was also less potent than hamamelis PC-cream. Erythema 4 to 8 h after the stripping of the horny layer was suppressed by hydrocortisone (P0.05). Inflammation was also less pronounced following low dose hamamelis PC-cream and chamomile cream. Hamamelis PC-cream, however, appeared less potent than hydrocortisone. In general, visual scoring was more discriminatory than chromametry.The results have demonstrated an anti-inflammatory activity of hamamelis distillate in a PC-containing vehicle. A fourfold increase of drug concentration, however, did not produce an increase in activity.

目的 探讨无张力疝修补术是否适用于嵌顿性（伴有全腹膜炎）腹股沟斜疝.方法 根据疝嵌顿后腹膜炎体征情况,统一手术切口、术式及抗生素使用剂量应用天数,对75例腹股沟嵌顿性斜疝患者与同期81例择期的腹股沟疝患者分为两组对比.采用巴徳mesh prefix plug定型产品做无张力疝修补术.比较两组患者手术时间、术后并发症、切口感染率、复发率.结果 与对照组（n=81）相比,研究组（n=75）手术时间明显延长差异有统计学意义（t检验P=4.96＜0.01 ）.术后并发症、切口感染率、复发率差异无统计学意义（χ^20.55,P=0.46;χ^22.73,P=0.09;χ^20.02,P=0.888）.结论 无张力疝修补术同样适用于伴有全腹膜炎的嵌顿性腹股沟斜疝.     

High success rate and considerable adverse events of pelvic prolapse surgery with Prolift: A single center experience

ObjectivesThe aim of this study was to analyze short-term outcomes of pelvic prolapse surgery using Prolift transvaginal mesh in a teaching hospital.Materials and MethodsThirty-four patients who received prolapse surgery with Prolift were followed up for 7–26 months. Assessment included pre- and postoperative Pelvic Organ Prolapse Quantification (POP-Q) stage, and Urogenital Distress Inventory (UDI)-6, and Incontinence Impact Questionnaire (IIQ)-7 scores. Surgical characteristics and adverse events during follow-up were also recorded.ResultsObjective and subjective data were available for 29 patients. The overall anatomical success rate was 96.5 % (28/29) after a mean of 18 ± 6.3 months follow-up. The POP-Q, UDI, and IIQ all improved significantly after surgery. Uterine sparing prolapsed surgery with Prolift unexpectedly yielded a cure rate of 100%. Ten adverse events occurred during and after prolapse surgery with dyspareunia (3/34) as the most common, followed by bladder injury (2/34).ConclusionsProlapse surgery with Prolift yielded a good anatomical outcome and satisfactory symptom improvement at different periods of follow-up, especially in uterus-sparing prolapse surgery. However, adverse events were not uncommon, and patients should be fully informed of all possible adverse events prior to surgery.
