A Systematic Review and Illustrative Case Presentation of Low-Grade Myofibroblastic Sarcoma (LGMS) of the Extremities.

Introduction: Low-grade myofibroblastic sarcoma (LGMS) is a rare tumor entity which occurs in the subcutaneous and deep soft tissues; it is less common in the bone with a predilection for the extremities and the head and neck region. As confirming the diagnosis is difficult and treatment strategies are not standardized, we aimed to identify patient and tumor characteristics, and to summarize treatment strategies and their clinical outcomes to guide surgeons.

Methods: Included were full articles reporting patients with histology of LGMS in the extremities, excluding tumors of the trunk.

Completion and publication of clinical trials in a cooperative group: a cohort study of trials of the Swiss Group for Clinical Cancer Research (SAKK).

Background: Premature trial discontinuation and non-publication of trial results are still major issues negatively affecting reliable evidence generation.

Objectives: To investigate trial completion and publication rate of cancer trials conducted within the Swiss Group for Clinical Cancer Research (SAKK).

Design: Cohort study of clinical trials.

[The sacroiliac joint and pain].

Pain caused by the sacroiliac joint (SIG) makes up a relevant proportion of lumbar back pain and can have a variety of specific and non-specific causes. The SIG represents the central link between the spine and the lower extremity. It is characterized by high stability and low mobility.

Tumor Suppressor Function of miR-127-3p and miR-376a-3p in Osteosarcoma Cells.

Since the introduction of high-dose chemotherapy about 35 years ago, survival rates of osteosarcoma patients have not been significantly improved. New therapeutic strategies replacing or complementing conventional chemotherapy are therefore urgently required. MicroRNAs represent promising targets for such new therapies, as they are involved in the pathology of multiple types of cancer, and aberrant expression of several miRNAs has already been shown in osteosarcoma.

[Pain generator sacroiliac joint : Functional anatomy, symptoms and clinical significance].

Background: The sacroiliac joint is a common cause of low back pain. Due to variable symptoms, the diagnosis is often very difficult. For diagnosis, systemic disease, as well as pathologies in the hips and lumbar spine must be excluded.

Optimization of the chicken chorioallantoic membrane assay as reliable in vivo model for the analysis of osteosarcoma.

Survival rates of osteosarcoma patients could not be significantly improved by conventional chemotherapeutic treatment regimens since the introduction of high-dose chemotherapy 35 years ago. Therefore, there is a strong clinical need for new therapeutic targets and personalized treatment strategies, requiring reliable in vivo model systems for the identification and testing of potential new treatment approaches. Conventional in vivo rodent experiments face ethical issues, are time consuming and costly, being of particular relevance in orphan diseases like osteosarcoma.

Cell-type-dependent activities of regulatory regions and E2 proteins derived from carcinogenic and non-carcinogenic human alphapapillomaviruses.

A large number of studies have revealed that persistent infections with certain human papillomavirus (HPV) types are necessary for the development of invasive cancer of the cervix. Recent studies have shown that not only do the major carcinogenic HPV types 16 and 18 encode E6 and E7 oncoproteins with immortalizing activity but also the very weakly or non-carcinogenic types 53, 66, 70 and 82. Currently, it is unknown whether transcriptional differences exist between these viruses that account for carcinogenicity in vivo.

Growth inhibition of HeLa cells is a conserved feature of high-risk human papillomavirus E8^E2C proteins and can also be achieved by an artificial repressor protein.

Infections with certain human papillomaviruses (HPV), such as type 16 (HPV16), 18, or 31, are a necessary risk factor for the development of cervical cancer. Transcript analyses of several HPV revealed that the viral E2 gene encodes both the E2 regulator protein and the E8∧E2C protein, which differ in their amino termini. Up to now, functional studies have focused on HPV31 E8∧E2C and demonstrated that it is a potent repressor of viral transcription and replication.

[Diagnosis of alcoholism in repeatedly intoxicated motorists. A study of 100 evaluations].

A total of 100 persons who had been repeatedly convicted of drunken driving were submitted to assessment by a medical expert. A series of uniform criteria were used to determine whether they suffered from alcoholism. The following methods of investigation were used: 1.
