Pectus excavatum and breast asymmetry: correction with breast augmentation

INTRODUCTION: Pectus excavatum is defined as a depression approaching the sternum and costal cartilages to the spine. Several theories explain its etiology, the most accepted of which is the exaggerated growth of the costal cartilages, which causes a posterior displacement of the sternum and consequent depression. The treatment includes correction of breast asymmetries by using silicone breast implants in patients without cardiopulmonary symptoms, only with esthetic complaints. METHODS: We reviewed the medical and photographic records of eight female patients diagnosed as having pectus excavatum, who underwent operation at a private hospital in the southern region of Brazil. These women sought consultation for local esthetic complaints and had no cardiorespiratory complaints. RESULTS: Six patients submitted only for breast prosthesis placement. One patient had a prosthesis implanted 15 years before, which was replaced by a new implant in the same plane. Another patient had undergone pectus repair with Nuss surgery 10 years before, and the patient came to the hospital with a complaint of hypomasty and asymmetry. The preferred anesthesia was general anesthesia in five of the cases. The prosthesis inclusion plane in almost all the cases was subglandular. Only one patient had a complication (seroma). CONCLUSIONS: In our sample, the placement of breast prostheses in the patients with pectus excavatum brought harmonic esthetic results, attenuating and/or masking the chest defect, with satisfactory esthetic results for the patients

Rhinophyma: a surgical treatment option

INTRODUCTION: Rhinophyma is a condition involving chronic inflammation of the nose and is characterized by progressive hypertrophy and hyperplasia of sebaceous glands and connective tissue. Rhinophyma leads to an appearance of nasal elephantiasis, which is caused by the congestion of dermis vessels. Its etiology is mostly associated with alcohol abuse. Rhinophyma is considered by some researchers to be an advanced stage of acne rosacea. Here, we report a case of rhinophyma that was surgically treated with decortication and electrocoagulation at the Plastic Surgery Service of the University Hospital of the Federal University of Santa Catarina. METHODS: A review of medical and photographic records of a case of rhinophyma was conducted. RESULTS: The patient was underwent surgical treatment with favorable outcomes. CONCLUSION: There are several treatments for rhinophyma, with decortication and electrocoagulation being an excellent therapeutic option

Weaning from mechanical ventilation in intensive care units across 50 countries (WEAN SAFE): a multicentre, prospective, observational cohort study

Background Current management practices and outcomes in weaning from invasive mechanical ventilation are poorly understood. We aimed to describe the epidemiology, management, timings, risk for failure, and outcomes of weaning in patients requiring at least 2 days of invasive mechanical ventilation. Methods WEAN SAFE was an international, multicentre, prospective, observational cohort study done in 481 intensive care units in 50 countries. Eligible participants were older than 16 years, admitted to a participating intensive care unit, and receiving mechanical ventilation for 2 calendar days or longer. We defined weaning initiation as the first attempt to separate a patient from the ventilator, successful weaning as no reintubation or death within 7 days of extubation, and weaning eligibility criteria based on positive end-expiratory pressure, fractional concentration of oxygen in inspired air, and vasopressors. The primary outcome was the proportion of patients successfully weaned at 90 days. Key secondary outcomes included weaning duration, timing of weaning events, factors associated with weaning delay and weaning failure, and hospital outcomes. This study is registered with ClinicalTrials.gov, NCT03255109. Findings Between Oct 4, 2017, and June 25, 2018, 10 232 patients were screened for eligibility, of whom 5869 were enrolled. 4523 (77·1%) patients underwent at least one separation attempt and 3817 (65·0%) patients were successfully weaned from ventilation at day 90. 237 (4·0%) patients were transferred before any separation attempt, 153 (2·6%) were transferred after at least one separation attempt and not successfully weaned, and 1662 (28·3%) died while invasively ventilated. The median time from fulfilling weaning eligibility criteria to first separation attempt was 1 day (IQR 0–4), and 1013 (22·4%) patients had a delay in initiating first separation of 5 or more days. Of the 4523 (77·1%) patients with separation attempts, 2927 (64·7%) had a short wean (≤1 day), 457 (10·1%) had intermediate weaning (2–6 days), 433 (9·6%) required prolonged weaning (≥7 days), and 706 (15·6%) had weaning failure. Higher sedation scores were independently associated with delayed initiation of weaning. Delayed initiation of weaning and higher sedation scores were independently associated with weaning failure. 1742 (31·8%) of 5479 patients died in the intensive care unit and 2095 (38·3%) of 5465 patients died in hospital. Interpretation In critically ill patients receiving at least 2 days of invasive mechanical ventilation, only 65% were weaned at 90 days. A better understanding of factors that delay the weaning process, such as delays in weaning initiation or excessive sedation levels, might improve weaning success rates
