A total of 379 patients (416 hands) with clinically diagnosed and electromyographically confirmed carpal tunnel syndrome were enrolled in a prospective study to determine the influence of a modified open decompression technique on postoperative scar discomfort. The new technique used in 184 patients (200 hands) is presented. Special attention was focused on identification and preservation of ma...

Background: Finger injuries are a common chief complaint in the emergency department (ED) and primary care setting. Repair of these injuries often require digital anesthesia through performing a digital nerve block (DNB). The two-injection subcutaneous volar block (SVB) and a two-injection dorsal digital block (DDB) are two of the most prevalently performed digital blocks in practice today. Thi...

introduction:spontaneous pneumomediastinum, pneumothorax, and subcutaneous emphysema are rare, but serious complications of inflammatory myopathies and occur more commonly in dm than pm. complications of dermatomyositis (dm) and polymyositis (pm), both of which can be fatal. case report:a 20-year-old woman was admitted with neck pain, dyspnea, cough, and fever. she had been diagnosed with derma...

INTRODUCTION Signet-ring cell carcinoma is a rare and aggressive variant of mucinous adenocarcinoma. Only a few cases of gallbladder adenocarcinoma with signet-ring cells have been reported and because of this there is a lack of knowledge about the behavior and biology of this pathology. CASE PRESENTATION We present the case of a 63-year-old Arab man with gallbladder signet-ring cell adenocar...

in this paper, we study some ring theoretic properties of the amalgamated duplication ring $rbowtie i$ of a commutative noetherian ring $r$ along an ideal $i$ of $r$ which was introduced by d'anna and fontana. indeed, it is determined that when $rbowtie i$ satisfies serre's conditions $(r_n)$ and $(s_n)$, and when is a normal ring, a generalized cohen-macaulay ring and finally a filter ring.

A dorsal penile nerve block (DPNB), ring block (RB), and eutectic mixture of local anesthetics (EMLA) all control pain effectively during neonatal circumcision (strength of recommendation [SOR]: A, systematic review). An RB may provide superior pain relief to DPNB and EMLA (SOR: B, limited-quality evidence). Using a Mogen clamp reduces pain by shortening procedure time (SOR: A, randomized contr...

in this paper, we introduce a class of $j$-quasipolar rings. let $r$ be a ring with identity. an element $a$ of a ring $r$ is called {it weakly $j$-quasipolar} if there exists $p^2 = pin comm^2(a)$ such that $a + p$ or $a-p$ are contained in $j(r)$ and the ring $r$ is called {it weakly $j$-quasipolar} if every element of $r$ is weakly $j$-quasipolar. we give many characterizations and investiga...

in this paper, we investigate various kinds of extensions of twin-good rings. moreover, we prove that every element of an abelian neat ring r is twin-good if and only if r has no factor ring isomorphic to z2  or z3. the main result of [24] states some conditions that any right self-injective ring r is twin-good. we extend this result to any regular baer ring r by proving that every element of a...

The ring-opening copolymerisation of a d -xylose 3,5-anyhydrosugar with isothiocyanates forms AB-type copolymers imidothiocarbonate linkages. Block copolymer synthesis, reaction kinetics, polymer degradation and metal absorption are explored.

cancer cell-stromal cell interaction plays a crucial role in the growth and invasion of tumor cells of various organs. it has been recently suggested that adipocytes and preadipocytes, two specific types of stromal cells, affect the biological behavior of variety of breast cancer cell lines. in spite of few investigations, there is a controversy in the literatures about the effects of adipocyte...
