An unusual presentation of tuberculosis

We describe a case of a male with no symptoms and normal chest X ray, diagnosed with TB. The chest computed tomography revealed a cavity formation on the upper left lobe

Recurrent catamenial hemothorax

Endometriosis is a common cause of chronic pelvic pain and infertility affecting women of reproductive age, but the disease in rare conditions may be extragenital so may be present with a variety of symptoms. This is a report of an unusual case of pelvic endometriosis that presented with a recurrent hemothorax

Carcinoid tumour behind bronchiectasis

This report describes a female patient with bronchiectasis, presented to our department with recurrent hemoptysis. Bronchoscopy revealed nothing else but blood arising from the upper lobe bronchus. High resolution computing tomography of the lung (HRCT) revealed bronchiectasis of the upper lobe. A right upper lobectomy was performed. Behind bronchiectasis multiple nodular lesions, 5-10 mm were observed. Histological and immunohistochemical examination revealed findings consistent with peripheral typical bronchial carcinoids

Association of ET-1 gene polymorphisms with COPD phenotypes in a Caucasian population

Background and Aim. The phenotypic expression of COPD consists of pulmonary emphysema and chronic bronchitis. An imprecise phenotypic definition may result in inconsistencies among genetic studies regarding COPD pathogenesis. Endothelin-1 gene polymorphisms have been linked to increased susceptibility of COPD development. The present study examined the involvement of +138 insA/delA and G198T ET-1 polymorphisms with emphysematous and bronchitic COPD phenotypes. Methods. In order to narrow down the phenotypic choices to either COPD-associated pulmonary emphysema or chronic bronchitis, a DLCO<60% predicted threshold was chosen as an indicator of severe emphysema.116 COPD smokers and 74 non-related, non-COPD smokers were evaluated. Results. Statistical analysis showed that the 4A allele of the +138insA/delA SNP and the 4A:T haplotype were associated predominantly with a chronic bronchitis phenotype, whereas the TT genotype of the G198T SNP was found to be protective from emphysema development. Conclusions. The presence of both the 4A and T allele seems to modify the final expression of COPD towards a chronic bronchitis phenotype, since the G:3A haplotype was associated with a predominantly emphysematous phenotype in our study

Androgens and male aging: current evidence of safety and efficacy

Many signs of aging, such as sexual dysfunction, visceral obesity, impaired bone and muscle strength, bear a close resemblance to features of hypogonadism in younger men. The statistical decline of serum testosterone in aging men is solidly documented. It has been presumed that the above features of aging are related to the concurrent decline of androgens, and that correction of the lower-than-normal circulating levels of testosterone will lead to improvement of symptoms of aging. But in essence, the pivotal question whether the age-related decline of testosterone must be viewed as hypogonadism, in the best case reversed by testosterone treatment, has not been definitively resolved. Studies in elderly men with lower-than-normal testosterone report improvement of features of the metabolic syndrome, bone mineral density, of mood and of sexual functioning. But as yet there is no definitive proof of the beneficial effects of restoring testosterone levels to normal in elderly men on clinical parameters. Few of these studies meet as yet rigorous standards of scientific enquiry: double-blind, placebo-controlled design of the study. The above applies also to the assessment of safety of testosterone administration to elderly men. There is so far no convincing evidence that testosterone is a main factor in the development of prostate cancer in elderly men and guidelines for monitoring the development of prostate disease have been developed. It is of note that there are presently no long-term safety data with regard to the prostate. Polycythemia is another potential complication of testosterone treatment. It is dose dependent and can be managed with dose adjustment

Potential prediction of acute biliary pancreatitis outcome on admission

Objectives This pilot study aimed to determine the feasibility of serum values of osteonectin, adiponectin, transforming growth factor beta 1, and neurotensin being used in clinical practice to predict the severity of acute pancreatitis. Methods Blood samples were collected from 45 consecutive newly diagnosed acute pancreatitis patients and 30 matched healthy controls. The 2 groups were matched according to age, sex, weight, height, diabetes, smoking, and alcohol consumption. The aforementioned markers were measured using enzyme-linked immunosorbent assay kits. Results Characteristics of acute pancreatitis patients and healthy controls were comparable. Osteonectin values differed significantly (P &lt; 0.0001). Median/lower quartile/upper quartile of osteonectin levels for acute pancreatitis patients and healthy controls were 263.5/110.3/490.36 and 63.2/46.1/87.2 ng/mL, respectively. Two patients died, 1 patient underwent necrosectomy, and 4 patients had a prolonged intensive care unit/hospital stay. Acute Physiology and Chronic Health Evaluation II and Systemic Inflammatory Response Syndrome scores neither predicted serum values of any of the measured substances nor the clinical outcome (need for intervention, prolonged intensive care unit/hospital stay and mortality). Osteonectin was the only independent predictor for clinical outcome (P = 0.007). Conclusions Serum osteonectin strongly discriminates healthy individuals from acute pancreatitis patients. Serum osteonectin shows promise in the prediction of the clinical outcome. © 2018 Wolters Kluwer Health, Inc. All rights reserved

Osteonectin as a screening marker for pancreatic cancer: A prospective study

Objective: Osteonectin plays a central role in various processes during the development of pancreatic adenocarcinoma. This prospective pilot study was performed to determine the feasibility of serum osteonectin as a screening tool for pancreatic cancer. Methods: Blood samples were collected from 15 consecutive patients with newly diagnosed pancreatic cancer and 30 matched healthy controls. Serum osteonectin was measured using an osteonectin enzyme-linked immunosorbent assay kit. The primary outcomes were the diagnostic performance of serum osteonectin and the threshold value for differentiation of patients from controls. Results: The median/quartile range of serum osteonectin in patients and controls were 306.8/288.5 ng/mL and 67.5/39.8 ng/mL, respectively. Osteonectin concentrations significantly differed among the study groups. A plasma osteonectin concentration of &gt;100.18 ng/mL as selected by the receiver operating characteristic curves demonstrated an estimated area under the curve of 86% for prediction of pancreatic cancer. Tumour size was a significant predictor of serum osteonectin. A statistically significant difference in serum osteonectin between T1/T2 and T3/T4 tumours was found. Post-hoc comparisons revealed statistically significant differences in the serum osteonectin among the control, T1/T2, and T3/T4 groups. Conclusion: Osteonectin may be used as a screening tool for pancreatic cancer, although this must be validated in prospective studies. © The Author(s) 2018

Pleural Mesothelioma in a young male patient

We present the case of a 33-year-old male patient suffering from lymphocytic pleural effusion, as a result of pleural mesothelioma. Mesothelioma is a malignant tumor of the pleura that is mainly caused by chronic exposure to asbestos fibers and more than 40 years of exposure are needed to develop the disease. Early studies on the relationship of asbestos and mesothelioma were issued in the 1960s. Fibers migrate from the parenchyma of the lung to the visceral pleura. It is widely known that asbestos is an oncogenic factor which can cause damage to DNA. A chest x-ray may reveal pleural effusion with or without pleural thickening, whereas a chest CT may also reveal pleural thickening, uniform and/or lobular. Specific tests, such as immunohistochemical staining, are used in order to help differential diagnosis. Extrapleural pneumonectomy is used as a therapeutic option which involves removal of the lung as well as both the visceral and parietal pleura, the affected part of the pericardium and diaphragm. Surgery should be followed up by radiotherapy and chemotherapy. The surgery may lead to a mean survival rate of approximately 9-21 months. The case presented underlines that in the event of pleural effusion with a lymphocyte type physicians should consider the possibility of a pleural mesothelioma during differential diagnosis, even in relatively young patients
