IntroductionIdiopathic pulmonary fibrosis (IPF) is an interstitial lung disease with a fatal prognosis. The diagnosis is made on the basis of high-resolution computed tomography and histological examination in selected cases.AimTo determine the risk of complications of open lung biopsy performed in patients with IPF.Material and methodsWe performed a retrospective analysis of 51 patients who underwent diagnostic excision of pulmonary parenchyma due to IPF in the period 1995–2014. We assessed the complication rate, length of drainage, postoperative period and 30-day mortality. We compared the results of treatment in the groups of patients operated on with thoracotomy and videothoracoscopy.ResultsThe mean age of patients was 58 (47% female, 53% male) forced vital capacity (FVC) was 81%, forced expiratory volume in 1 s (FEV1) was 80% and body mass index (BMI) was 27 kg/m2. Thoracotomies (lateral, muscle sparing or anterior) were performed in 20 patients between 1995 and 2012 and videothoracoscopy in 31 patients operated on in the years 2009–2014. Patients in study groups did not differ considering age (p = 0.40), gender (p = 0.81), FVC (p = 0.08), FEV1 (p = 0.13) or BMI (p = 0.75). Postoperative complications occurred in 3.9% of patients (atrial arrhythmia 1.9% and recurrent pneumothorax 1.9%) with equal incidence in both study groups (p = 0.75). Median stay after thoracotomy was 4 days while after videothoracoscopy it was 3 days (p = 0.04).ConclusionsOpen lung biopsy performed on patients with IPF is a safe procedure. Open lung biopsy performed through thoracotomy could be as safe as through VATS, however is characterized by longer postoperative stay.
Introduction: Hyperhidrosis is a condition that significantly impairs patients' quality of life. Qualification for treatment in most cases is based only on subjective evaluation of symptoms without objective confirmation. Aim: To evaluate the differences between subjective and objective evaluation of sweating among medical students. Material and methods: There were 179 participants involved in the study. Subjective evaluation of sweating was conducted using the Hyperhidrosis Disease Severity Scale and Numeric Rating Scale in 4 body areas: the face, palms, armpits and abdomino-lumbar area. Objective evaluation of sweating was performed using gravimetry. Results: The prevalence of hyperhidrosis in gravimetric measures was 1.12%. In subjective evaluation hyperhidrosis (HDSS 3 or 4) was present in 11.17% of cases. There was no significant difference in subjective evaluation of hyperhidrosis between men and women (15% vs. 9.24%; p = 0.32). In gravimetry men showed a higher perspiration rate on the face (5.85 vs. 3.38; p < 0.05) and in the armpits (17.27 vs. 9.12; p < 0.05). Individuals with body mass index ≥ 25 kg/m² reported hyperhidrosis more often (28% vs. 8.44%; p < 0.05); however, in gravimetric evaluation, beside the facial area, no significant differences in above-mentioned groups were observed. Conclusions: There is a discrepancy between subjective and objective methods of evaluating sweating.
The search for optimal material for aortic infection reconstruction is ongoing. Our study presents the early and mid-term results of surgeon-constructed porcine pericardial tubes in the in-situ reconstruction of abdominal aortic infections, focusing on the safety as well as the durability of surgeon-created tubes. We performed a retrospective analysis of 8 patients treated for native aortic ( n = 3) and aortic graft infections ( n = 5) with surgeon-created tubes made of porcine pericardium patch (8 × 14 cm NO-REACT Ⓡ, BioIntegral Surgical Inc., Mississauga, ON, Canada). There were 7 males and 1 female, aged 68.5 (±4.8 years). Three patients had an aorto-enteric fistula. Technical success was obtained in all patients. Thirty-day mortality was 12.5% ( n = 1). Mid-term follow-up was 12 months (2–63 months). One-year mortality was 37.5% ( n = 3). Reintervention rate was 28.5% ( n = 2). False aneurysm rate in the follow-up was 14.2% ( n = 1). Surgeon-constructed porcine pericardial tubes seem to be a promising alternative as a replacement for native as well as graft-related abdominal aortic infections. The mid-term durability is encouraging, once the infection is controlled in cases with successful fistula repair and in native aortic infections patients. Further observations on larger groups, in longer follow-ups are necessary to confirm these preliminary observations.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
