RESUMEN

BACKGROUND: Acrochordons are common and benign skin tumours. A few studies with contradictory results have been reported regarding the abnormalities of carbohydrate and/or lipid metabolisms in patients with acrochordons. OBJECTIVES: We aimed to determine if the presence of acrochordons could be a marker of diabetes, hyperlipidemia, liver enzyme abnormalities and hypertension by comparing with a control group. METHODS: A total of 110 patients having two or more acrochordons and age- and gender-matched 110 controls were included in the study. Localization, size and the total number of acrochordons were recorded in the patient group. Fasting plasma glucose (FPG), serum lipids and liver enzyme levels were tested in patient and controls. All participants underwent a standard 2-h oral glucose tolerance test with 75 g glucose. Diabetes mellitus and impaired glucose intolerance were diagnosed according to the American Diabetes Association criteria. Arterial blood pressures were measured in two groups. RESULTS: A total of 56 patients and 10 controls were diagnosed with overt DM. Thirteen per cent of the patients and 9% of controls had an impaired glucose tolerance test. The difference was statistically significant for the diagnosis of DM and not significant for the impaired glucose tolerance. The mean levels of FPG, total cholesterol, LDL cholesterol, triglyceride, aspartate aminotransferase, alanine aminotransferase, gamma-glutamyltransferase and alkaline phosphatase were significantly higher in patients than those in controls. Furthermore, serum levels of HDL were less in patients. Patients with acrochordons had higher systolic and diastolic blood pressures than controls. CONCLUSIONS: The results of our study suggest that acrochordons may represent a cutaneous sign for impaired carbohydrate or lipid metabolism, liver enzyme abnormalities and hypertension.

RESUMEN

Cell-based medicinal products (CBMPs) are rapidly gaining importance in the treatment of life-threatening diseases. However, the analytical toolbox for characterization of CBMPs is limited. The aim of our study was to develop a method based on flow imaging microscopy (FIM) for the detection, quantification and characterization of subvisible particulate impurities in CBMPs. Image analysis was performed by using an image classification approach based on a convolutional neural network (CNN). Jurkat cells and Dynabeads were used in our study as a representation of cellular material and non-cellular particulate impurities, respectively. We demonstrate that FIM assisted with CNN is a powerful method for the detection and quantification of Dynabeads and cells with other process related impurities, such as cell agglomerates, cell-bead adducts and debris. By using CNN, we achieved a more than 50-fold lower misclassification rate compared with the use of output parameters from the FIM software. The limit of detection was ~15 000 beads/mL in the presence of ~500 000 cells/mL, making this approach suitable for the detection of these particulate impurities in CBMPs. In conclusion, CNN-assisted FIM is a powerful method for the detection and quantification of cells, Dynabeads and other subvisible process impurities potentially present in CBMPs.

RESUMEN

PURPOSE: Hydatid cyst (HC) is a serious health problem in developing countries. The aim is to discuss the clinical information, surgical and puncture-aspiration-injection-re-aspiration (PAIR) treatments, and results of patients with HC in a developing country. METHODS: Patients were analyzed in terms of gender, age, presenting complaint, misdiagnosed HC, cyst location, cyst number, cyst size, liver HC type according to the World Health Organization Informal Working Group Echinococcosis (WHO-IWGE) classification, pulmonary HC, hemithorax locations, treatments and interventions, duration of hospitalization, follow-up period, postoperative complications, and recurrence. RESULTS: There were 106 girls and 99 boys with a mean age of 10.7 years. The most common location was the liver (n = 170), and the second most common was the lungs (n = 67). The mean diameter for liver HC was 86.27 mm, and it was 73.90 mm for pulmonary HC. PAIR was performed on 61 patients with liver HC using interventional radiology. 109 patients underwent surgery. The most common complications were cystobiliary fistula in liver HC and atelectasis in pulmonary HC. CONCLUSION: HC should be one of the first considerations in the differential diagnosis in all anatomical areas in the presence of suspicious radiological and clinical findings in endemic regions.

RESUMEN

BACKGROUND: Behçet disease (BD) is a chronic and multisystemic vasculitis characterized with recurrent oral and genital ulcers, uveitis, arthritis and skin manifestations. The highest prevalence of the disease has been reported in regions historically involved in the Silk Road routes. OBJECTIVE: We aimed to analyse Behçet literature and evaluate whether there is a concordance between ancient Silk Road regions and the distribution of publication productivity. METHODS: The bibliometric analysis of the publications published during 1980-2014 using Thomson Reuters Web of Science database was performed. We generated infographics of productivity and also analysed the correlations among economical productivities, technological advancement levels and humanity index and productivity performances of 78 countries in Behçet literature. RESULTS: Turkey ranked first in Behçet literature with 1837 articles followed by Japan and the USA. Turkey, Tunisia and Israel occupied the first three places in productivity. Significant correlations were noted between 2014 gross economic and technological indices and publication numbers of the countries. We found that European countries had high productivity, although they had low prevalence of BD. We detected no concordance between the productivity density of the countries and the ancient Silk Road routes. CONCLUSION: Most publications were reported from developed countries although undeveloped or developing countries had higher prevalence of BD. Physicians in undeveloped and developing countries should be supported and encouraged to perform novel studies on BD.

RESUMEN

BACKGROUND: In this study we examined the effects of two different repeated Extracorporeal Shock Waves (ESW) on the consolidation period of the distraction osteogenesis (DO) of the rabbit mandible using stereological, radiological and immunohistochemical methods. MATERIAL AND METHODS: DO was performed unilaterally in the mandible of 18 New Zealand rabbits (six months old, weighing between 2.5-3 kg). In the consolidation period, rabbits were divided into three groups randomly after the distraction period. The distraction zone of the mandible was received no treatment as controls (E0*2). Group 2 (E 500*2) received ESWT (twice 500 impulses at 14 kV and 0.19 mJ/mm2 energy) in the first and fourth days of the consolidation. Group 3 (E1000*2) treated with ESWT (twice 1000 impulses at 14 kV and 0.19 mJ/mm2 energy) in the first and fourth days of the consolidation period. After the sacrification, radiologically bone mineral density, new bone formation, new fibrous tissue and new vessel formation were analyzed by stereological. RESULTS: It was found a statistically significant difference between the study groups and control group in the bone mineral density measurements and the highest value was in the E1000*2 group. In the stereological analysis, new bone formation was highest in the E1000*2 group and there was a significant difference compared to the other groups (E0*2 and E500*2) (p=0.000). The lowest connective tissue volume was found in the E500*2 and there was a significant difference compared to the other groups (E0*2 and E1000*2) (p=0.000). The volume of the new vessel was highest in the E500*2 and lowest in the E0*2 group. It was found statistically significant difference between the values of the study and control groups. CONCLUSIONS: Interestingly, we found that repetition of the 1000 impulses ESWT accelerated the consolidation, 500 impulses ESWT extended consolidation period of the DO.

RESUMEN

BACKGROUND: Dermatology literature lacks a study investigating both histopathological and dermatoscopic features of dermatofibroma. OBJECTIVE: To analyse histopathological, dermatoscopic and digital microscopic features of dermatofibromas. METHODS: Two hundred dermatofibromas and 190 patients were included and retrospectively evaluated. Nine histopathological and ten dermatoscopic patterns were used to classify the lesions. We identified four different types of dermatofibroma in digital microscopy. RESULTS: The mean age of the patients was 42.18 ± 13.72 years. Dermatofibroma was more common in females (67%) and the male to female ratio was 1:1.97. The most common location was leg (41%). The most frequent histopathological variant was fibrocollagenous type (49%). Grenz zone was the most common histopathological finding (89%). The most frequent digital microscopic type was type 1 (63%). CONCLUSIONS: We found that palisading variant displayed only pattern 6 in dermatoscopy and cellular variant showed type 3 significantly in digital microscopy.

RESUMEN

AIM: Scrotal calcinosis is a rare and benign condition characterized by multiple calcific deposits occurring in scrotum and formed as nodules and lumps within scrotal skin with any systemic metabolic disorder. The so-called idiopathic scrotal calcinosis does not appear to be idiopathic, but rather a process of dystrophic calcification of epidermal cysts. Histological examination shows calcium deposites with in the dermis that may be surrounded with histiocytes and an inflammatory giant cell reaction. The aim of this paper was to detect dystrophic calcification of epidermal cysts and to take attention to the incorrect terminology of "idiopathic calsification". METHODS: This is a two-centered study of scrotal calcinosis with 17 cases, on which clinical and histopathological examinations were conducted. RESULTS: The patients we examined all had scrotal epidermoid cysts in varying stages of inflammation coexisted with scrotal calcinosis. Some cyts (52.9%) had intact epithelial walls, others (35.2%) showed rupture of their epithelial walls associated with the presence of keratin fibers and calcium granules in the surrounding dermis and all had naked calcium deposits lying in the dermis. CONCLUSION: The spectrum of the changes that we experienced in the histology, coupled with the normal values in the biochemical profile, shore up the theory of dystrophic calcification of epithelial cysts. During the time first these cysts become inflamed than rupture in the and calcium depocytes replase with the cysts.

RESUMEN

We present here the case of a 31-year-old man that developed facial petechiae after unsedated upper gastrointestinal endoscopy. The lesions disappeared completely after 5 days. In English literature, only one patient similar to ours has been reported. The most likely explanation of this condition is a Valsalva maneuver that raised the intrathoracic or abdominal pressure and resulted in a rupture of capillaries in the skin. Endoscopists should therefore be aware of this rare and reversible complication.

RESUMEN

This retrospective review of data from a single burn centre revealed a sharp decrease in the mortality associated with childhood burn. Between January 1998 and January 2006, 1035 children were admitted to our burn unit in Ankara. The overall mortality was 5.8%, falling from 23% between 1998 and 2000 to 5.6% between 2001 and 2005. Scalds were commonest among the younger and flame and electrical burns among the older children. Flame burns were associated with the largest burned body surface areas and highest mortality rates. Electrical burns remained a major health problem with significant amputation rates and lengths of hospital stay. Candidaemia was a mortal consequence of burn. Renovation of the unit with changes in the management of burn victims from conservative treatment to more up-to-date approaches were associated with improved outcomes.
