Primary Care Physician Attitudes and Intentions Toward the Use of HIV Pre-exposure Prophylaxis in Adolescents in One Metropolitan Region

Purpose

Understanding the attitudes of physicians toward the use of pre-exposure prophylaxis (PrEP) for HIV prevention among youth is critical to improving access to PrEP. We examined PrEP-related attitudes among physicians who provide primary care to 13- to 21-year-old adolescents.

Giant gastrointestinal stromal tumour of rare sarcomatoid epithelioid subtype:Case study and literature review

Gastrointestinal stromal tumours(GISTs) are the most common mesenchymal tumours of the gastrointestinal tract,but they represent less than 3% of all gastrointestinal tract malignancies.This is a detailed case study of a 52-yearold male patient treated for very uncommon histological subtype of gastric GIST with atypical clinical presentation,asymptomatic progress and late diagnosis.The resected tumour,giant in diameters,was confirmed to represent the most rare histopathologic subtype of GISTs- sarcomatoid epithelioid GIST.We report this case and review the literature with a special focus on pathomorphological evaluation,biological aggressiveness and prognostic factors.To our knowledge this is the first report of giant GIST of very uncommon sarcomatoid epithelioid subtype.It is concluded that clinicians should pay attention to the fact that initial diagnosis may be delayed due to mildly asymptomatic and non-specific clinical presentation.Asymptomatic tumours diagnosed at a late stage,which is often the case,can be large on presentation.Prognosis for patients diagnosed with GIST depend on tumour size,mitotic rate,histopathologic subtype and tumour location.That is why early diagnosis and R0 resection,which is usually feasible and safe even in giant gastric sarcomatoid epithelioid subtype of GISTs,are the key factors for further treatment and good prognosis.     

The first case of genetically confirmed sparganosis (Spirometra erinaceieuropaei) in European reptiles

Parasitology Research - Sparganosis is a zoonosis caused by the spargana (larvae) of Spirometra sp. (Diphyllobothriidae). Reptiles are particularly important vectors for the transmission of this...     

Pregnancy and delivery in women with esophageal varices due to hepatic vein thrombosis

Aim: Retrospective analysis of the course of pregnancy, labor and mode of anesthesia in women with portal hypertension and esophageal varices induced by portal vein thrombosis.

Material: From 2000 to 2012 seven pregnant were admitted. None had liver transplantation (Ltx), the varicose have been in the 1st stage. Each of them has been consulted by the obstetrician, transplant surgeon and anesthetist. The patient condition during pregnancy, labor and postpartum period was analyzed.

Results: Pregnancy in five cases proceeded physiologically. In one threatening miscarriage was diagnosed and treated with gestagens, two patients had tocolytic. One required variceal banding twice. In three thrombocytopenia worsened, with platelet count Conclusion: Patients with portal hypertension can deliver at term. It is a high-risk pregnancy. In this group it is desirable to shorten the second stage of labor or complete it by c-section under general anesthesia with remifentanyl which allows getting desired analgesia without complications in the newborn. Surveillance of pregnant with portal hypertension must include monitoring of liver function and coagulation disorders.     

Factors Affecting Sexual Function and Body Image of Early-Stage Breast Cancer Survivors in Poland: A Short-Term Observation

Introduction

Knowing the important factors influencing sexual function and body image might facilitate the recovery process of breast cancer survivors. Surgery type, relationship quality, and partner support might be modified to create a space for psychosexual intervention.

BCL11B,FLT3, NOTCH1 and FBXW7 mutation status in T-cell acute lymphoblastic leukemia patients

T‐cell acute lymphoblastic leukemia is a heterogeneous malignancy originating from developing lymphocyte precursors likely due to mutations in genes regulating thymocyte differentiation. Here, we characterized mutation status of BCL11B and FLT3 genes, presumably involved in T-ALL, together with FBXW7 and NOTCH1 as known players in T-ALL in 65 pediatric T-cell acute lymphoblastic leukemia patients. We also aimed at the assessment of prognostic value of NOTCH1 and FBXW7 mutations in ALL-IC BFM 2002 protocol.FLT3 and BCL11B mutations were detected in 3% and 2% of patients, respectively. FBXW7 mutations were observed in 8% of patients, while NOTCH1 was mutated in 40%. No correlation was found between NOTCH1 and FBXW7 mutations and traditionally used clinical factors or molecular features. In total we have detected nine mutations, which have not been previously described by others. Eight of them were found in NOTCH1 and one in BCL11B gene.Observed frequencies of NOTCH1 and FBXW7 are in line with previous reports, thus confirming postulated participation of these two genes in T-ALL pathomechanism. Moreover, we report on mutation frequency of FLT3 and BCL11B, not extensively studied in T-ALL so far. Finally, we suggest a putative role of BLC11B as an oncogene in T-ALL pathogenesis.
