Pelvic floor and abdominal muscle cocontraction in women with and without pelvic floor dysfunction: a systematic review and meta-analysis

2019

There is an ongoing discussion regarding abdominal muscle (AbM) and pelvic floor muscle (PFM) synergism. Therefore, this study aimed to investigate the cocontraction between AbMs and PFMs in women with or without pelvic floor dysfunction (PFD). The following databases were searched up to December 21, 2018: MEDLINE, EMBASE, LILACS, PEDro and CENTRAL. We included any study that assessed the cocontraction between PFMs and AbMs in women with and without PFD. Two reviewers independently screened eligible articles and extracted data. The outcomes were extracted and analyzed as continuous variables with random effect models. Twenty studies were included. A meta-analysis did not show differences in…

Little is known about somatosensory evoked potentials (SEPs) from muscle stimulation compared to that from skin stimulation. The current study examined this issue in the full SEP spectrum (0 - 440 ms). The aims of the study were to (1) establish the dynamics of early to late latency SEPs from intramuscular stimulation in contrast to surface stimulation, (2) compare the effect of non-painful and painful stimuli on SEP latencies and amplitudes of the two methods, and (3) investigate to which extent these results can be shared between the median nerve innervated thenar site and ulnar nerve innervated hypothenar site. Stimuli were delivered (2 Hz) at a non-painful and a painful intensity above …

Abdominal wall defects: two- versus three-dimensional ultrasonographic diagnosis.

2001

We diagnosed 12 cases of abdominal wall defects. The cases diagnosed occurred in 6 fetuses with omphalocele, 3 with gastroschisis, 2 with prune-belly syndrome, and 1 with pentalogy of Cantrell. Except for 1 case of gastroschisis first diagnosed on the basis of three-dimensional ultrasonography at 14 weeks' gestation, all cases were first detected by two-dimensional transabdominal ultrasonography and then reevaluated with three-dimensional ultrasonography using multiplanar and orthogonal plane modes. Although the original diagnosis was accurate on the basis of two-dimensional ultrasonography in 11 of 12 cases, additional information was obtained by three-dimensional scanning in all cases. Ou…

Orthopedic-orthodontic treatment of the patient with Turner's syndrome: Review of the literature and case report.

2018

Aims Turner syndrome (TS) patients have phenotypical variable presentations and they are more susceptible to endocrine, auto-immune, and structural anomalies. Typical clinical characteristics are short stature and premature ovarian insufficiency. Patients with TS show a typical cranial-facial morphology with bi-maxillary bi-retrusion, high-arched palate, micrognathia, and class II malocclusion. Aim of our study is to present the orthopedic-orthodontic treatment approach of a young TS patient and data of stability after 7 years. Methods and results A careful analysis of anamnestic data was performed. After extraoral and intraoral examination, cephalometric measurements and examination of mod…

Ocular Motor Palsy After Spinal Puncture

2017

Abstract Ocular motor palsy is a rare but alarming complication of subarachnoid puncture. In order to better understand this condition, a literature search was performed in English of PubMed articles for cranial nerves III, IV, and VI palsies after spinal puncture. Sixty-five articles (dated 1930–2015) were identified, and 114 cases were obtained for analysis. Subarachnoid anesthesia was the most frequent cause (45.6%), with a higher incidence for females than males. The age of patients was 40.24 ± 13.35 years (age range, 6–71 years). The sixth cranial nerve was the most commonly involved (92.1%), with higher frequency in the right eye. Palsy onset started 7.30 ± 4.09 days after puncture. D…

Quantitative study of muscle fibre atrophy and restitution after nerve grafts.

1976

Our comparative experimental studies on rabbits using clinical, electromyographical, and quantitative histological examinations of long autologous and homologous nerve grafts in 35 rabbits, paying special attention to quantitative histological changes in the gastrocnemius muscles, allow the statement that, compared to the short homografts, the long homografts showed worse results. Moreover, it became obvious that the regeneration rate of autografts was not influenced by increasing the lengths of the grafts. The answer to the question of how far even longer grafts may influence the quality of regeneration will need further investigations.

Deflazacort in Duchenne dystrophy: Study of long-term effect

1994

A randomized double-blind controlled trial of deflazacort was conducted in 28 Duchenne muscular dystrophy patients either treated with deflazacort 2.0 mg/kg alternate-day therapy or placebo. The deflazacort group showed significant improvement in climbing stairs (P < 0.01), in rising from a chair, Gower's maneuver, and walking (P < 0.0025) after 6 months of treatment. After 1 year, all the above changes remained significantly improved and the MRC index was significantly better (P < 0.05) in the treated group. After 2 years, a significant change was found in the MRC index: higher scores in walking, chair rising (P < 0.02), and grade and time of Gower's maneuver (P < 0.05) were found. The mea…

Fructose 2,6-bisphosphate and glycolytic flux in skeletal muscle of swimming frog

1990

AbstractGlycolytic flux in skeletal muscle is controlled by 6-phosphofructokinase but how this is achieved is controversial. Brief exercise (swimming) in frogs caused a dramatic increase in the phosphofructokinase activator, fructose 2,6-bisphosphate, in working muscle. The kinetics of phosphofructokinase suggest that in resting muscle, the enzyme is inhibited by ATP plus citrate and that the increase in fructose 2,6-bisphosphate is part of the mechanism to activate phosphofructokinase when exercise begins. When exercise was sustained, fructose 2,6-bisphosphate in muscle was decreased as was the rate of lactate accumulation. Glycolytic flux and the content of fructose 2,6-bisphosphate appea…
