BACKGROUND: Fournier's gangrene (FG) is a rapidly evolving necrotizing fasciitis of the perineum and the genital area, the scrotum as it most commonly affects man in the vast majority of cases. It is polymicrobial in origin, due to the synergistic action of anaerobes and aerobes and has a very high mortality. There are many predisposing factors including diabetes mellitus, alcoholism, immunosuppression, renal, and hepatic disease. The prognosis of the disease depends on a lot of factors including but not limited to patient age, disease extent, and comorbidities...

A large body of evidence supports the notion that incorrect or insufficient nutrition contributes to disease development. A pivotal goal is thus to understand what exactly is appropriate and what is inappropriate in food ingestion and the consequent nutritional status and health. The effective application of these concepts requires the translation of scientific information into practical approaches that have a tangible and measurable impact at both individual and population levels. The agenda for the future is expected to support available methodology in nutrition research to personalize guideline recommendations, properly grading the quality of the available evidence, promoting adherence to the well-established evidence hierarchy in nutrition, and enhancing strategies for appropriate vetting and transparent reporting that will solidify the recommendations for health promotion...

Objectives: The symbiosis of Trichomonas vaginalis and Mycoplasma hominis is the first described association between two obligate human parasites. Trichomonas is the niche and the vector for the transmission of M. hominis infection. This clinically significant symbiosis may affect T. vaginalis virulence and susceptibility to treatment. The aims of this study were to investigate the intracellularly present Mycoplasma and Ureaplasma species in T. vaginalis strains isolated from the vaginal discharge of infected women as well as to trace the diversity pattern among the species detected in the isolated strains...

Hemangioma is the most common benign hepatic tumor. We present the case of a patient with a giant symptomatic hemangioma, treated with segmental liver resection using the Da Vinci Robotic System. A 38-year-old woman presented to our surgical out-patient Department complaining about abdominal discomfort and recurrent episodes of acute abdominal pain. CT-scan and MRI imaging of the abdomen revealed the presence of a giant hepatic hemangioma (>5 cm) involving segments VI and VII. Robotic right segmental hepatectomy was performed...

Individual patient data (IPD) meta-analyses are increasingly common in the literature. In the context of estimating the diagnostic accuracy of ordinal or semi-continuous scale tests, sensitivity and specificity are often reported for a given threshold or a small set of thresholds, and a meta-analysis is conducted via a bivariate approach to account for their correlation. When IPD are available, sensitivity and specificity can be pooled for every possible threshold. Our objective was to compare the bivariate approach, which can be applied separately at every threshold, to two multivariate methods: the ordinal multivariate random-effects model and the Poisson correlated gamma-frailty model...

During embryogenesis, the thymus and inferior parathyroid glands develop from the third pharyngeal pouch and migrate to their definite position. During this process, several anatomic variations may arise, with the thyroid being one of the most common sites of ectopic implantation for both organs. Here, we report the case of a young female patient, who underwent total thyroidectomy for papillary carcinoma of the thyroid. The patient's history was remarkable for disorders of the genitourinary system. Histologic examination revealed the presence of well-differentiated intrathyroidal thymic tissue, containing an inferior parathyroid gland...

Fragment Based Drug Discovery (FBDD) is an increasingly popular method to identify novel small-molecule drug candidates. One of the limitations of the approach is the difficulty of accurately characterizing weak binding events. This work reports a combination of X-ray diffraction, surface plasmon resonance (SPR) experiments and molecular dynamics (MD) simulations, for the characterisation of binders to different isoforms of the cyclophilin (Cyp) protein family. Although several Cyp inhibitors have been reported in the literature, it has proven challenging to achieve high binding selectivity for different isoforms of this protein family...

Systematic reviews and meta-analyses are increasingly common. This article aims to provide guidance for people conducting systematic reviews relevant to the healthcare of older people. An awareness of these issues will also help people reading systematic reviews to determine whether the results will influence their clinical practice. It is essential that systematic reviews are performed by a team which includes the required technical and clinical expertise. Those performing reviews for the first time should ensure they have appropriate training and support...

BACKGROUND: Congenital toxoplasmosis is a serious but preventable and treatable disease. Gestational screening facilitates early detection and treatment of primary acquisition. Thus, fetal infection can be promptly diagnosed and treated and outcomes can be improved. METHODS: We tested 180 sera with the Toxoplasma ICT IgG-IgM point-of-care (POC) test. Sera were from 116 chronically infected persons (48 serotype II; 14 serotype I-III; 25 serotype I-IIIa; 28 serotype Atypical, haplogroup 12; 1 not typed)...

REVIEW

Corticosteroids are among the most commonly prescribed drugs by physicians of nearly all medical specialties. Their widespread use in clinical neurology is based either on randomized studies or, most often, on clinical experience and experts' opinion. Besides the well-known adverse effects of corticosteroids, they may also induce or worsen certain neurological disorders. The purpose of this review is to highlight the negative impact of these drugs on these disorders with emphasis on putative pathophysiological mechanisms of this association...

Evolution has conserved "economic" systems that perform many functions, faster or better, with less. For example, three to five leukocyte types protect from thousands of pathogens. To achieve so much with so little, biological systems combine their limited elements, creating complex structures. Yet, the prevalent research paradigm is reductionist. Focusing on infectious diseases, reductionist and non-reductionist views are here described. The literature indicates that reductionism is associated with information loss and errors, while non-reductionist operations can extract more information from the same data...

Abdominal wall tumors are sometimes diagnosed as metastases of ovarian cancer, however, primary peritoneal tumors should be taken into consideration in the final diagnosis. A 49-year-old female patient was admitted in our Department for the excision of a pulpable abdominal wall lump, with no other abnormalities shown on imaging investigation. On histology examination, the excised specimen revealed characteristics of metastatic high-grade serous ovarian carcinoma. Total hysterectomy, bilateral oophorectomy, omentectomy and appendectomy were performed...

BACKGROUND: γδ T cells are important for both protective immunity and immunopathogenesis during malaria infection. However, the immunological processes determining beneficial or detrimental effects on disease outcome remain elusive. The aim of this study was to examine expression and regulatory effect of the inhibitory receptor T-cell immunoglobulin domain and mucin domain 3 (TIM3) on γδ T cells. While TIM3 expression and function on conventional αβ T cells have been clearly defined, the equivalent characterization on γδ T cells and associations with disease outcomes is limited...

Purpose: Histone deacetylase inhibitors (HDACi) are epigenome-targeting small molecules approved for the treatment of cutaneous T cell lymphoma and multiple myeloma. They have also demonstrated clinical activity in AML, non-small cell lung cancer and estrogen receptor-positive breast cancer, and trials are underway assessing their activity in combination regimens including immunotherpy.  However, there is currently no clear strategy to reliably predict HDACi sensitivity. <p>In colon cancer cells, apoptotic sensitivity to HDACi is associated with transcriptional induction of multiple immediate-early (IE) genes...

REVIEW
Natalia G Vallianou, Christos Kazazis, George Ioannidis
Diabetic hepatosclerosis is a novel entity that has recently been introduced by reviewing archived liver biopsies as a non-cirrhotic form of peri-sinusoidal fibrosis with basement membrane formation. Diabetic hepatosclerosis is usually characterized by an indolent clinical course. Serum aminotransferase levels are normal or minimally elevated, but elevated alkaline phosphatase levels is usually present. Clinically relevant to DH is the co-existence of other diabetic microvascular complications in the same patient, such as ESRD on long-term dialysis or renal transplantation, retinopathy, or neuropathy...
