Previous research has suggested that adolescents with myelomeningocele and shunted hydrocephalus (MMH) have difficulties with aspects of executive functioning and, in turn, with functional independence. There is little research, however, examining patterns of executive functioning across adolescence in this population. The goal of this cross-sectional study was to examine parent ratings of exec...

Hepatitis A virus (HAV) has been adapted to grow efficiently in primate and some nonprimate cell lines but not in cells of murine origin. To understand the inability of the virus to grow in mouse cells, we studied the replication of HAV in immortalized and nontransformed MMH-D3 mouse liver cells, which require growth factors and collagen to maintain their phenotype. HAV grew in MMH-D3 cells tra...

Manual material handling (MMH) tasks can be found in most workplaces and they may constitute a risk factor for work-related musculoskeletal disorders (WMSDs). This study was conducted to determine the prevalence of WMSDs and to compare MMH loads with the acceptable weight and force limits among Iranian casting workers. Data were collected from 50 workers of casting workshops who performed MMH t...

BACKGROUND Hemorrhoid surgery is mostly being performed as an inpatient procedure under general or regional anesthesia. However, there was a trend toward performing anorectal surgery in an ambulatory setting utilizing local anesthesia. OBJECTIVE To propose an easy technique of perianal block for ambulatory hemorrhoidectomy. MATERIAL AND METHOD Between January 2004 and June 2007, 61 patients...

BACKGROUND Transanal hemorrhoidal dearterialization (THD), a new approach for patients who would otherwise require an operative hemorrhoidectomy, accomplishes hemorrhoidal symptom relief with far less postoperative pain than an operative hemorrhoidectomy. METHODS THD, an ambulatory procedure, employs a specially designed proctoscope coupled with a Doppler transducer to allow identification an...

Studies were conducted to define the specific changes in the urinary porphyrin excretion pattern (porphyrin profile) and the time course of those changes in rats exposed to mercury as methyl mercury hydroxide (MMH) at 5 or 10 ppm in the drinking water for up to 30 weeks. The urinary porphyrin profile elicited by MMH is uniquely characterized by highly elevated levels of 4- and 5-carboxyl porphy...

context hemorrhoidal disease is the most common anorectal disorder that requires surgical intervention. hemorrhoids require treatment when they result in symptoms such as bleeding or prolapse. surgical intervention is indicated for significant prolapse, and a number of accepted and viable methods are available for treating prolapsing hemorrhoids that do not reduce spontaneously (grade iii and i...

Maternal mental health (MMH) problems are associated with lack of confidence in one's parenting, overly lax or too harsh discipline, and child academic underperformance. We asked if parenting mediates the effect of MMH problems on academic outcomes even among mothers with serious mental illness (n=164). Structural equation analyses show a significant association between MMH problems and permiss...
