BACKGROUND: Donor site seroma is the most common complication after latissimus dorsi (LD) flap harvest. This study aimed to evaluate the efficacy of negative-pressure wound therapy (NPWT) in preventing donor site seroma formation after the harvest of an LD flap for breast reconstruction. METHODS: In this prospective matched-pair study, 40 patients in whom an LD flap was harvested for breast reconstruction were enrolled. NPWT was used in 20 patients, and in a control group composed of another 20 patients, the conventional donor site dressing technique was used...

INTRODUCTION: High-tension electricity can cause devastating injuries that may result in abdominal wall loss, visceral damage, and sometimes major threat to life. The visceral organ may be exposed after debridement and require flap cover, but the tensile strength of abdominal wall may be lack even if flap transplanted. METHODS: From April 2007 through May 2015, 5 patients with severe abdominal electrical injury were treated at our hospital. Exploratory laparotomy was performed based on their clinical manifestations and debridement findings of abdominal wall at early stage, and decision regarding technique for reconstruction of abdominal wall was based on an assessment of the location and extent of the defect...

Introduction We aimed to identify nerve entry points (NEP) of superficial skeletal muscles obtained by dissection of 20 human cadavers and to compare those to motor points (MP) previously obtained by electrical stimulation. Methods The biceps brachii- (BB), trapezius (TZ), latissimus dorsi (LD), pectoralis major (Pmaj) and pectoralis minor muscles (Pmin) were dissected from human cadavers. Mean values ±SD of the NEPs of each muscle were calculated. F-tests with Bonferroni corrections were used to compare NEPs and MPs...

Gymnasts perform handstands on various apparatus, both in stable and unstable conditions. Such performances require specific muscle activation, which should differ depending on the condition and expertise of the gymnast. Therefore, the aim of the study was to evaluate 1) the difference in electromyography (EMG) between handstands performed on three apparatus (floor, rings and parallel bars); and 2) the difference between young and well-trained adult gymnasts. Ten adult (25 ± 3.94 years) and 15 young (13.9 ± 0...

BACKGROUND AND OBJECTIVE: The clinical application of laser-assisted vascular anastomosis is afflicted by unreliable and low bonding strengths as well as tedious handling during microvascular surgery. The challenge to be met arises from the flow-off of the chromophore during soldering that changes the absorption and stains the surrounding tissue, leading to an uncontrollable thermal damage zone. In this study, we investigated the feasibility to produce an indocyanine green (ICG)-loaded patch by electrospinning and tested its applicability to both in vitro and in vivo microvascular laser soldering...

Supernumerary or accessory heads of the biceps brachii are persistent muscular structures which can vary in number and location in the arm. Variations in other arm muscles, such as the coracobrachialis, can accompany supernumerary biceps brachii musculature in the upper limb. In this case report, we describe two rare muscular variants in a single adult male: a four-headed biceps brachii and the muscular elevator of the latissimus dorsi tendon. Additionally, accessory muscles of the brachialis and flexor digiti minimi brevis were identified in the upper limb...

PURPOSE: Hormone (anti-estrogen) therapy (HT) plays a major role in hormone receptor-positive breast cancer management. The latest guidelines propose to extend the duration of adjuvant treatment from 5 to 10 years. The association between HT and thromboembolic or microvascular complications during breast reconstruction has been investigated. However, while estrogens play a crucial role in wound healing, no study has assessed the impact of tamoxifen or aromatase inhibitors on other postoperative complications, including wound healing complications...

The case of a giant thoracic desmoid tumour in a 44-year-old woman, who presented two years following a breast reconstruction with a latissimus dorsi (LD) flap and implant, is reported. Clinical findings included a rapidly growing, painless mass. Computed tomography (CT) suggested skin and intercostal soft tissue invasion. The tumour was resected en bloc with the LD muscle, implant capsule and underlying rib segments. The resultant thoracic and abdominal wall defects were reconstructed with Dualmesh® and polypropylene meshes respectively...

A high variability in functional tests and activities used during the pulmonary rehabilitation has been observed in post-intensive care unit (ICU) patients, and the best battery of tests to adopt has not been described yet. We tested in patients admitted in a post-ICU Step Down Unit the ability to perform the more frequent functional volitional tests. The relations of each single volitional test with general disability and dyspnea at discharge were also evaluated. Ten volitional tests including: bedside spirometry test (ST: FEV1%, FVC%), maximal inspiratory pressure (MIP), maximal expiratory pressure (MEP), Peak Expiratory Flow during Cough (PCEF), Quadriceps Muscle Strength (QMS), latissimus Dorsi and teres Major Strength (DMS), Brachial biceps Muscle Strength (BMS), effort tolerance measured by sit-to-stand test, Takahashi test and 6-Min Walking Test (6MWT), were evaluated in post-ICU patients at entry and discharge from in-hospital rehabilitation...
