Obstetric Brachial Plexus Palsy and Functional Implications: Which Joint in the Upper Extremity Is More Closely Associated?

The objective of this study is to examine the correlation between the active range of motion (ROM) of the affected upper extremity and functional capacity in children with Obstetric Brachial Plexus Palsy (OBPP) who have undergone the modified Hoffer tendon transfer technique. The study cohort comprised 52 children with OBPP, aged 4-14 years, who had undergone a shoulder tendon transfer. The ROM was quantified using a goniometer, while functionality was evaluated through the administration of the Brachial Plexus Outcome Measure (BPOM).

ADAM19 cleaves the PTH receptor and associates with brachydactyly type E.

Brachydactyly type E (BDE), shortened metacarpals, metatarsals, cone-shaped epiphyses, and short stature commonly occurs as a sole phenotype. Parathyroid hormone-like protein (PTHrP) has been shown to be responsible in all forms to date, either directly or indirectly. We used linkage and then whole genome sequencing in a small pedigree, to elucidate BDE and identified a truncated disintegrin-and-metalloproteinase-19 (ADAM19) allele in all affected family members, but not in nonaffected persons.

The effect of botulinum toxin application on latissimus dorsi and teres major muscles in patients with brachial plexus birth palsy: An electron microscopic and clinical study.

Background: In brachial plexus birth palsy (BPBP), botulinum toxin may be utilized to prevent glenohumeral dysplasia and to maintain the stable growth of the glenohumeral joint. Repeated injections may cause muscular atrophy and their functional effects are uncertain. The aim of this study was to compare the microstructure and the function of the muscles that received two injections before transfer with the muscles that were not injected.

An unusual cause of posterior interosseous nerve palsy and contribution of ultrasonography to electromyography in a patient with neurofibroma.

Neurofibroma, a benign peripheral nerve sheath tumor, represents a rare cause of posterior interosseous nerve syndrome. Electrodiagnostic studies may not identify the exact site of nerve compression, a possible lesion that compresses the nerve and do not provide information about the morphological changes. Ultrasound is a cost-effective, practical modality that provides the opportunity for dynamic tracking in the peripheral nerves, and it is widely considered as the initial imaging modality for peripheral nerves.

Microwave assisted synthesis, experimental and theoretical characterization and antibacterial activity screening of novel azomethine compounds containing thiophene and aminophenol functionality.

Eight new azomethine compounds (3a-3h) containing thiophene and aminophenol functionality were synthesized in excellent yields by using conventional heating and microwave assisted synthesis methods. The structures of newly synthesized compounds were characterized by spectroscopic techniques such as UV-Vis, FTIR, H and C NMR and elemental analysis. UV-Vis and H NMR results show that all compounds prefer the phenol-imine tautomer form in solvent media.

Phosphodiesterase 3A and Arterial Hypertension.

Background: High blood pressure is the primary risk factor for cardiovascular death worldwide. Autosomal dominant hypertension with brachydactyly clinically resembles salt-resistant essential hypertension and causes death by stroke before 50 years of age. We recently implicated the gene encoding phosphodiesterase 3A (); however, in vivo modeling of the genetic defect and thus showing an involvement of mutant PDE3A is lacking.

Reorganization of chromosomal interactions in the 2q37-deletion syndrome.

Chromosomes occupy distinct interphase territories in the three-dimensional nucleus. However, how these chromosome territories are arranged relative to one another is poorly understood. Here, we investigated the chromosomal interactions between chromosomes 2q, 12, and 17 in human mesenchymal stem cells (MSCs) and MSC-derived cell types by DNA-FISH We compared our findings in normal karyotypes with a three-generation family harboring a 2q37-deletion syndrome, featuring a heterozygous partial deletion of histone deacetylase 4 () on chr2q37.

Reliability and validity of the Brachial Plexus Outcome Measure in children with obstetric brachial plexus palsy.

Study Design: Clinical measurement and cross-sectional study.

Introduction: Numerous scales have been developed to examine activities of daily living and function in children with brachial plexus palsy. The Brachial Plexus Outcome Measure (BPOM) scale was developed in 2012 by Emily S.

Lowering dialysate sodium improves systemic oxidative stress in maintenance hemodialysis patients.

Purpose: The purpose of the current prospective study was to evaluate the effects of low sodium dialysate on oxidative stress parameters, blood pressure (BP) and endothelial dysfunction in maintenance hemodialysis (HD) patients.

Methods: After baseline measurements were taken, the dialysate sodium concentration was reduced from 140 to 137 mEq/L. Oxidative stress parameters and flow-mediated dilatation (FMD %) were measured before and after 6 months of HD with low sodium dialysate.

Distally based subcutaneous veins for venous insufficiency of the reverse posterior interosseous artery flap.

Background: The reverse posterior interosseous artery flap (PIAF) provides soft, thin, and pliable tissue for upper extremity reconstruction without sacrificing any major arteries of the hand. The authors performed a new technique that included one extra distally based subcutaneous vein within the pedicle to diminish venous insufficiency and they aimed to present the results of reconstruction with this technique.

Patients And Methods: Twelve patients with a mean age of 30 years (range 5-52 years) underwent reverse PIAF surgery.

Clinical effects of phosphodiesterase 3A mutations in inherited hypertension with brachydactyly.

Autosomal-dominant hypertension with brachydactyly is a salt-independent Mendelian syndrome caused by activating mutations in the gene encoding phosphodiesterase 3A. These mutations increase the protein kinase A-mediated phosphorylation of phosphodiesterase 3A resulting in enhanced cAMP-hydrolytic affinity and accelerated cell proliferation. The phosphorylated vasodilator-stimulated phosphoprotein is diminished, and parathyroid hormone-related peptide is dysregulated, potentially accounting for all phenotypic features.

PDE3A mutations cause autosomal dominant hypertension with brachydactyly.

Cardiovascular disease is the most common cause of death worldwide, and hypertension is the major risk factor. Mendelian hypertension elucidates mechanisms of blood pressure regulation. Here we report six missense mutations in PDE3A (encoding phosphodiesterase 3A) in six unrelated families with mendelian hypertension and brachydactyly type E (HTNB).

Epicardial fat tissue thickness is correlated with diminished levels of co-enzyme Q10, a major antioxidant molecule among hemodialysis patients.

Objectives: Accelerated atherosclerosis is the major cause of mortality in patients on chronic maintenance hemodialysis (HD). Epicardial fat tissue (EFT) is a new risk factor in cardiovascular disease (CVD). The aim of this study was to evaluate the relation between plasma coenzyme Q10 levels (Co-Q10) which is a potent physiologic antioxidant and EFT thickness in HD patients.

Decreased serum selenium levels are correlated with diminished coronary flow reserve among hemodialysis patients.

Cardiovascular diseases are the main reason of high mortality among hemodialysis patients. Decreased serum selenium levels may have a role in accelerated atherosclerosis in this patient group. The hypothesis of this study was to show a correlation between decreased serum selenium levels and coronary flow reserve as an indicator of endothelial dysfunction and atherosclerosis in HD patients.

Epicardial fat thickness is associated with impaired coronary flow reserve in hemodialysis patients.

Cardiovascular disease (CVD) is the main cause of mortality in hemodialysis (HD) patients. Epicardial fat tissue (EFT) is a new risk factor in CVD. The aim of this study was to evaluate the association between EFT and coronary artery flow reserve (CFR), which is an early indicator of endothelial dysfunction in coronary vessels of HD patients.
