Complications of Botulinum toxin A: An update review.

2021

Cosmetic surgery procedures have increased manifolds all over the world owing to the ever-increasing demand of people to look beautiful and young. Injectable treatments like botulinum toxin are becoming more popular owing to their rapid, well-defined, and lasting results for the reduction of facial fine lines, wrinkles, and facial rejuvenation. These emerging treatments are quite safe but can have certain adverse effects. In this article, we have highlighted the complications and side effects of botulinum toxin based on the anatomical location. The possible causes and precautions to prevent these complications are also discussed. The search of literature included peer-reviewed articles incl…

Tackling the Problem of Data Imbalancing for Melanoma Classification

2016

Comunicació de congrés presentada a: 3rd International Conference on Bioimaging, BIOIMAGING 2016 - Part of 9th International Joint Conference on Biomedical Engineering Systems and Technologies, BIOSTEC 2016, Roma, Italy Malignant melanoma is the most dangerous type of skin cancer, yet melanoma is the most treatable kind of cancer when diagnosed at an early stage. In this regard, Computer-Aided Diagnosis systems based on machine learning have been developed to discern melanoma lesions from benign and dysplastic nevi in dermoscopic images. Similar to a large range of real world applications encountered in machine learning, melanoma classification faces the challenge of imbalanced data, where …

Three-dimensional helical computed tomography in prenatal diagnosis of fetal skeletal dysplasia

2013

Objectives (1) To study the use and diagnostic value, as a complement to ultrasound, of helical computed tomography (helical CT) to differentiate normal fetuses from cases of skeletal dysplasia; (2) to define the most relevant indications for helical CT; and (3) to evaluate its diagnostic performance with respect to radiological criteria considered discriminatory. Methods This was a retrospective study from 2005 to 2008 in 67 pregnant women who underwent helical CT after 26 weeks of gestation for suspected fetal skeletal dysplasia due to fetal shortened long bones on ultrasound (≤ 10thpercentile), either alone or associated with other bone abnormalities. The results were compared with pedia…

F75Determining fetal lung volume using three-dimensional-ultrasonography

2000

Background The aim of the study was to establish fetal lung, thoracic and heart volume nomograms using 3D-ultrasonography. Method For this purpose 115 fetuses were examined (between 18 and 33 weeks of gestation) using Voluson 530D (Kretztechnik, Austria) ultrasound device and 5 MHZ three-dimensional annular volume transducer. Lung volumes of 15 fetuses suffering from skeletal dysplasia, renal agenesis or hydrothorax and secondary pulmonary hypoplasia were compared with previously established nomograms. Results Lung volumes in the pathologic group of fetuses compared to the nomograms were below the 5% for gestational age. Conclusion The encouraging first results suggest that this method coul…

204 Role of minimally invasive surgery versus open approach on the clinical and surgical outcome in patients with early stage uterine carcinosarcomas…

2020

Objectives The aim of this retrospective study was to compare surgical and survival outcome in only patients with early stage uterine carcinosarcomas (UCSs) managed by laparotomic surgery (LPT) versus minimally invasive surgery (MIS). Methods Data were retrospectively collected in 4 Italian different institutions. Inclusion criteria were: UCS diagnosis confirmed by the definitive histological examination, and stage I or II according to the FIGO staging system. Results Between August 2000 and March 2019, the data relative to 150 patients bearing UCSs were collected: of these, 82 were defined as early stage disease (stage I-II) based on the histological report at the primary surgery, and thus…

Filamin C variants are associated with a distinctive clinical and immunohistochemical arrhythmogenic cardiomyopathy phenotype.

2020

Background: Pathogenic variants in the filamin C (FLNC) gene are associated with inherited cardiomyopathies including dilated cardiomyopathy with an arrhythmogenic phenotype. We evaluated FLNC variants in arrhythmogenic cardiomyopathy (ACM) and investigated the disease mechanism at a molecular level. Methods: 120 gene-elusive ACM patients who fulfilled diagnostic criteria for arrhythmogenic right ventricular cardiomyopathy (ARVC) were screened by whole exome sequencing. Fixed cardiac tissue from FLNC variant carriers who had died suddenly was investigated by histology and immunohistochemistry. Results: Novel or rare FLNC variants, four null and five variants of unknown significance, were id…

Radiation exposure to the hands and the thyroid of the surgeon during intramedullary nailing.

1998

Abstract During 41 procedures of intramedullary nailing of femoral and tibial fractures, the primary surgeon and the first assistant wore ring dosimeters on their dominant index fingers. While the average fluoroscopy time per procedure was 4.6 min, the average dose of radiation to the dominant hand of the primary surgeon was 1.27 mSv and 1.19 mSv to the first assistant. The dose limit for the extremities is 500 mSv per year, as recommended by the International Commission on Radiological Protection. Extrapolation of the mean dose of the primary surgeon and first assistent per procedure of 1.23 mSv leads to the result that the recommended dose limit of 500 mSv would only be exceeded if more t…

Plunging Ranula in a 78- year- old Male ? a rare case report

2018

The term Ranula is a Latin word meaning frog. It refers to a bluish translucent cystic lesion in the floor of the mouth resembling the underbelly of a frog. Ranulas can be true cysts occurring due to ductal obstruction of the sublingual gland or a minor salivary gland or a pseudocyst as a result of ductal injury leading to extravasation and accumulation of saliva in the surrounding tissues. Clinically ranulas present as intraoral or plunging ranulas. The prevalence of ranula is 0.2% per 1000 patients Ranulas account for 6% of all salivary gland cysts. Ranulas are more common in children and young adults. However the plunging type occurs most commonly in the later third decade. The diagnosis…
