Prevalence of Psychiatric Comorbidity in Symptomatic Gastroesophageal Reflux Subgroups

Digestive Diseases and Sciences - Limited data exist regarding the psychosocial aspects of gastroesophageal reflux disease (GERD). Some GERD subgroups, such as functional heartburn and...     

Reliability and construct validity of the SF-36 in Turkish cancer patients

In this study, we assessed the reliability and construct validity of the SF-36, Turkish version on 419 cancer patients. Cronbach’s α coefficients surpassed the 0.70 criterions for all subscales indicating good internal consistency. Results of the test–retest method showed that the stability coefficients for the eight subscales of the SF-36 ranged between 0.81 and 0.94. Principal components factor analysis with varimax rotation confirmed the presence of seven factors in the SF-36: physical functioning, role limitations due to physical and emotional problems, mental health, general health perception, bodily pain, social functioning, and vitality. In conclusion, the Turkish version of the SF-36 is a suitable instrument that could be employed in cancer research in Turkey.     

Factors associated with functional disability in patients with rheumatoid arthritis

To determine factors associated with functional disability in patients with rheumatoid arthritis (RA). A total of 100 RA patients were reviewed retrospectively. Multiple regression analysis was used to investigate associations between the dependent variable (health assessment questionnaire) and independent variables (age, disease duration, hand grip strength values, VAS and DAS-28 scores). Main factors associated with functional disability were disease activity score as reflected in a high score on the DAS-28 (r = 0.68, p < 0.001) and disease duration (r = 0.23, p < 0.05). Increased age, decreased grip strength and high pain level were associated with lower functional ability, but none of these was a predictor of disability in the regression model. The results indicate that age, disease duration, disease activity, pain intensity and hand grip strength are related to physical disability in patients with RA. However, only disease activity has an impact on physical function. Thus, treatment of RA patients should focus on early inhibition of disease activity in order to achieve a good functional outcome.     

Maple syrup urine disease: diffusion-weighted MRI findings during acute metabolic encephalopathic crisis

Maple syrup urine disease (MSUD) is caused by a genetic defect of branched-chain amino acids, which include leucine, isoleucine and valine. We report diffusion-weighted imaging (DWI) findings in a newborn child with MSUD who presented with acute metabolic encephalopathic crisis. DWI (b = 1,000 s/mm(2)) showed high signal localized within the myelinated white matter (WM) areas including the cerebellar white matter, pons, bulbus, cerebral peduncles, lentiform nucleus, posterior limbs of the internal capsules, corona radiata and bilateral perirolandic cortex. The apparent diffusion coefficient values of these regions were markedly low in the affected areas. The presence of these findings was considered cytotoxic or intramyelinic edema evidenced by restricted water diffusion. In conclusion, our findings suggest that during the acute phase and early encephalopathic crisis stage of MSUD, DWI can demonstrate the involvement of myelinated WM in newborns.     

The effect of testosterone replacement therapy on bladder functions,histology, apoptosis,and Rho-kinase expression in bladder outlet obstruction and hypogonadism rat model

Background/aimThe effect of testosterone replacement therapy was investigated on bladder functions, histology, apoptosis as well as Rho-kinase expression in the rat bladder outlet obstruction (BOO) and hypogonadism models. Materials and methods30 mature male rats divided into 4 groups: sham group (n = 8), BOO group (n = 8), BOO + orchiectomy group (n = 7), BOO + orchiectomy + testosterone (T) treatment group (n = 7). Cystometric findings, apoptosis index, Rho-kinase (ROCK-2) expression, and smooth muscle/collagen ratio were compared. Results BOO did not change ROCK-2 expression level, compared to sham group (P > 0.05). However, when compared to BOO group (P < 0.01), BOO + orchiectomy led ROCK-2 increase. The testosterone treatment failed to reverse the up-regulation of ROCK-2 induced by orchiectomy although it tended to lower ROCK-2 level. Compared to sham group (P = 0.002), changes in maximal bladder capacity and leak point pressure were higher (P = 0.026, P = 0.001), and bladder compliance was lower in BOO group. Also, the apoptosis index was different between the two groups (P = 0.380). Smooth muscle/collagen ratio was higher in BOO + orchiectomy + T group than in BOO + orchiectomy group (P = 0.010).ConclusionsThe research draws attention to alternating treatment approaches in case of the presence of hypogonadism and BOO.
