Excessive adipose tissue is associated with inflammation, oxidative stress (OS), insulin resistance and activation of the renin angiotensin-aldosterone system (RAAS). Therefore, adipose tissue dysfunction plays an important role in the development of CKD.With the advancement of urine test automation and the large-scale application of quality management policies, the source of the most crucial errors has become the pre-analytical phase. This study is an attempt to compare the results obtained from the examination of urine strips with those obtained by microscopic examination of urinary sediment, highlighting discordant results. This observational study was conducted between February and August 2019 in a private medical laboratory in Mureş County, and 2,600 urine samples were analyzed. We calculated the sensitivity, specificity, positive predictive value, negative predictive value for leukocytes, nitrites and red blood cells, taking as reference the microscopic examination of urine summary screening. Urine samples were collected from patients who presented to the laboratory. The 2,600 urine samples were analyzed using strips with 10 parameters glucose, protein, bilirubin, urobilinogen, pH, specific density, red blood cells, nitrite, and leukocytes, and then using the microscope to examine the urinary sediment. We identified a small percentage (1.92%) of inconsistencies from the 2,600 samples of urine, between urinalysis and the microscopic examination and we identified the causes. The most common discordant results were false-negatives for nitrite (72%), followed by false-positives results for red blood cells (22%), false-negative results for leukocytes (16%), false-negative results for red blood cells (4%) and false-positives for leukocytes (4%). The study confirmed that discrepancies appear despite the proper instruction of patients.The rareness of H-type tracheoesophageal fistula in conjunction with its unspecific clinical presentation and wide range of anatomical presentation makes its diagnosis and treatment a problematic topic for both ear, nose and throat (ENT) specialists and pediatric surgeons worldwide. Symptoms and clinical signs of H-TOF are easily misleading. Diagnostic methods, most of the times, are dependent on the physician's experience; therefore, various errors may be made. We analyzed our experience in managing H-TOF cases over the last 15 years. Advice and strategies of action for health professionals directly involved in the diagnosis and treatment were identified, but also errors and mistakes while managing 6 cases. We analyzed 'red flags' but also important steps in the practical safety concerning this rare congenital malformation. Choosing the surgical access for division of the fistula throughout the cervical or thoracic approach is sometimes difficult. A scrupulous perioperative planning is mandatory. A dynamic overview of the patient's presentation never underestimating the subtlety of H-TOF presentation should be conducted for its early recognition and achieving best outcomes.A granular cell tumor (GCT) is a rare neoplasia that originates from Schwann cells. It usually appears in the skin or soft tissues, but it may occur anywhere in the body. The gastrointestinal tract is an unusual developmental site for a GCT, the esophagus being the most common site of origin for this tumor. The stomach is one of the most unique sites of origin for GCT, with less than 80 cases being mentioned in the literature. Histologically, GCTs consist of fusiform and polygonal cells, with granular cytoplasm, arranged in compact 'nests'. Immunohistochemically, these tumors show positivity for S100 protein, CD68, CD56 and, in a smaller percentage, they are positive for other antibodies, most notably inhibin alpha. Androgen Receptor high throughput screening We report the case of a 52-year-old woman with a solitary GCT that had developed in the gastric cardia, discovered on a routine gastroscopy and successfully treated by endoscopic submucosal dissection.Cancer immunotherapy has shifted the paradigm in cancer treatment in recent years. Immune checkpoint blockage (ICB), the active cancer vaccination and chimeric antigen receptor (CAR) for T-cell-based adoptive cell transfer represent the main developments, achieving a surprising increased survival in patients included in clinical trials. In spite of these results, the current state-of-the-art immunotherapy has its limitations in efficacy. The existence of an interdisciplinary interface involving current knowledge in biology, immunology, bioengineering and materials science represents important progress in increasing the effectiveness of immunotherapy in cancer. Cutaneous melanoma remains a difficult cancer to treat, in which immunotherapy is a major therapeutic option. In fact, enhancing immunotherapy is possible using sophisticated biomedical nanotechnology platforms of organic or inorganic materials or engineering various immune cells to enhance the immune system. In addition, biological devices have developed, changing the approach to and treatment results in melanoma. In this review, we present different modalities to modulate the immune system, as well as opportunities and challenges in melanoma treatment.Isotretinoin is an oral derivate of vitamin A that has been used since 1982 for the treatment of multiple dermatologic conditions such as severe acne, rosacea, scarring alopecia, ichthyosis or non-melanoma skin cancer prophylaxis. The recommended dose is 0.5-1 mg/kg/day for a period of 4-6 months in sebaceous gland pathologies. There are many adverse effects caused by isotretinoin but by far the most important is the teratogenicity induced by this drug which is estimated to have a 20-35% risk to infants that are exposed to isotretinoin in utero and includes numerous congenital defects such as craniofacial defects, cardiovascular and neurological malformations or thymic disorders. Isotretinoin induces apoptosis and cell cycle arrest in human sebocytes, emphasizing these as processes associated with its teratogenic effect. The aim of this review is to analyze the latest literature data regarding the teratogenic effect of isotretinoin for both fertile females and males and its biological effects underlying the occurrence of congenital malformations under the influence of isotretinoin.
