Article Synopsis
  • Musculoskeletal disorders (MSDs) frequently develop in dentistry students, particularly affecting the spine, but there’s limited research on the relationship between spinal curve changes and MSDs in this population.
  • A study involving 73 dentistry students tracked spinal changes over five years using a Spinal Mouse® device and found that spinal curve parameters varied by gender and changed throughout their education.
  • Despite observing changes in spinal curves, no significant links were found between these objective findings and the self-reported incidence of MSDs among the students, suggesting the need for further research on this issue.

Purpose: The deep fascia has recently been a current topic in many medical fields, including rehabilitation. Some research has already focused on assessing deep fascia, however results of individual authors differ in certain aspects. This study focuses on the inter-rater reliability of ultrasound (US) measurement of the thickness of deep fascia and loose connective tissue (LCT).

Article Synopsis
  • Musculoskeletal disorders (MSDs) are a major issue for dentists and dental students, with a study tracking 73 students over five years highlighting common complaints like neck and lower back pain.
  • Statistically significant increases in neck pain were observed from the first to the fifth year (up 15%), while lower back pain's increase was not significant (up 6.8%).
  • Factors such as age, participation in high-level sports, and regular exercise showed significant impact on the prevalence of neck and back pain among these students.

Musculoskeletal disorders (MSDs) frequently occur among dental practitioners and present a significant occupational burden with an early onset in the dentists' career. This study aimed to analyze the five-year development of self-reported overall MSDs among the dentistry students during the course of their studies and to assess the possible influence of the risk as well as protective factors. The questionnaire inquiry was performed among the first-year dentistry students, regarding the occurrence of MSDs and the presence of potential risk and protective factors.

Ulnar neuropathy at the elbow (UNE) is commonly encountered in clinical practice. It results from either static or dynamic compression of the ulnar nerve. While the retroepicondylar groove and its surrounding structures are quite superficial, the use of ultrasound (US) imaging is associated with the following advantages: (1) an excellent spatial resolution allows a detailed morphological assessment of the ulnar nerve and adjacent structures, (2) dynamic imaging represents the gold standard for assessing the ulnar nerve stability in the retroepicondylar groove during flexion/extension, and (3) US guidance bears the capability of increasing the accuracy and safety of injections.

Unlabelled: : Objective: The aim of the study CERES (CzEch REkovelle real life Study) was to gather experience with the use of a novel gonadotrophine, to evaluate the efficacy of follitropin delta in Czech clinical settings and to compare our results with the clinical trial ESTHER-1.

Methods: Individualized follitropin delta daily dose in µg based on the patient’s anti-Müllerian hormone (AMH) level and body weight (AMH < 15 pmol/ L: 12 µg/ d; AMH > 15 pmol/ L: 0.10–0.

Objective: Vaginismus is caused by involuntary spasm of muscle surrounding the vaginal wall, a condition which makes it impossible to have a comfortable sexual intercourse. Due to its significant psychogenic part this topic is often neglected by specialists, however it is a very sensitive one for women patients. We are bringing a summary of literature dealing with vaginismus, clarifying the possibilities of diagnostics, therapy and we are discussing relation of this dysfuntion to reproduction.

This article is the second part of an evaluation of musculoskeletal disorders (MSDs) prevalence among dental students. As the majority of complaints are in the back region, there is an endeavor to analyze objectively the disorders in this region. One of the non-invasive and non-radiation methods is the spinal curve mapping using the Spinal Mouse® device (Idiag AG, Fehraltorf, Switzerland).

Musculoskeletal disorders (MSDs) frequently occur among dentists and dental students. The first aim of this study was to gather and analyze information about the prevalence of symptoms of MSDs. The second aim was to determine a correlation between subjectively described complaints and the results of an objective examination of the spine using the Spinal Mouse® device; that part is described in the second section of this article.

We introduce an ergonomic positioning for sonographic scanning of elbow joint where the patient is lying semisupine on the examination bed. This is in contrast with the conventional positioning where the patient is sitting on the edge of the bed or across the table on a chair. Our proposed positioning is more comfortable for both the patient and ultrasound practitioner.

Context/objective: Traumatic damage to the cervical spinal cord is usually associated with a disruption of the autonomic nervous system (ANS) and impaired cardiovascular control both during and following exercise. The magnitude of the cardiovascular dysfunction remains unclear. The aim of the current study was to compare cardiovascular responses to peak voluntary exercise in individuals with tetraplegia and able-bodied participants.

Background And Objective: To determine the prevalence of markers of inherited thrombophilia in patients with severe form of ovarian hyperstimulation syndrome (OHSS) DESIGN AND METHODS: Blood samples were analysed for markers of thrombophilia (mutation of factor V - Leiden, mutation of methylentetrahydrofolat reductase (MTHFR) C677T and mutation of prothrombin G20210A). The study group consisted of women who had undergone controlled ovarian hyperstimulation for IVF complicated by severe OHSS (group A, n = 50). Results were compared with two controls groups - women who underwent ovarian hyperstimulation for IVF without developing OHSS (group B, n = 93) and healthy pregnant women with no history of infertility (group C, n = 196).
