Comparison of transperineal and transvaginal sonography in predicting preterm delivery

PURPOSE: A major advantage of transperineal sonography (TPUS) is its ability to evaluate the cervix without causing any distortion. This study was performed to compare transvaginal sonography (TVUS) and TPUS at 24 weeks of gestation in predicting preterm delivery in low-risk pregnancy. METHODS: Three hundred fifty-seven pregnant women underwent TVUS and TPUS at 24 weeks of gestation. The relationship between cervical length and preterm delivery was assessed. Accuracy values of TVUS and TPUS at 24 weeks of gestation were compared in predicting preterm delivery. RESULTS: Preterm delivery (before 36 weeks of gestation) occurred in 22 pregnancies (6.2%). Mean cervical lengths measured by TVUS and TPUS were significantly different in preterm and term delivery groups (P < 0.05). Areas under the curves were 0.801 and 0.857 for the transvaginal and transperineal measurements, respectively. The coefficient of correlation between the transvaginal and transperineal cervical length measurements was 0.83. TPUS had a sensitivity of 77% in predicting preterm delivery, with a false-positive rate of 17% and a relative risk of 4.5 at the 32.5-mm cutoff value. CONCLUSIONS: When the cervix is well visualized, TPUS can predict preterm delivery as accurately as TVUS.     

Relationship between impulsivity and obsession types in obsessive-compulsive disorder

Objective: Impulsivity is an important aspect of obsessive-compulsive disorder (OCD) which is classified under a new heading in DSM-5 with other impulsivity related disorders like trichotillomania. Due to its heterogeneous nature, different obsessions may be linked to varying impulsivity profiles. Aim of this study was to investigate the impulsivity traits and their relationship with obsession types by comparing OCD subjects who display sexual, religious and aggressive obsessions or other obsessions to healthy controls.

Methods: Outpatients with OCD (n?=?146) and healthy controls (n?=?80) were evaluated with Sociodemographic Data Form, SCID-I, SCID non-patient version, Yale-Brown Obsessive Compulsive Scale (Y-BOCS) and Barratt Impulsiveness Scale (BIS-11).

Results: BIS-11 attention scores of the OCD group were significantly higher than healthy subjects. In patients with sexual, aggressive, religious obsessions, BIS-11 attention scores were significantly higher than those who have other obsession types and that of controls.

Conclusions: Higher levels of attentional impulsivity, particularly in patients suffering from sexual, aggressive or religious obsessions suggest a common diathesis for a dysfunction in neural correlates corresponding to these symptoms. The results of our study may promote further studies conducted with more advanced and objective neuropsychometric tests evaluating features of the clinical course, neurobiology and the response to OCD treatment.     

Investigation of various antibiotic combinations using the E-Test method in multiresistant Pseudomonas aeruginosa strains

BACKGROUND: Antibiotic combinations are frequently used in order to obtain wide-spectrum effects in the treatment of serious infections such as septicemia and endocarditis, and also to produce an in vivo effect against strains which are defined as resistant to the known inhibiting or fatal dose of one antibiotic. The synergistic effects of combinations such as aminoglycoside + beta-lactam, aminoglycoside + quinolone and quinolone + beta-lactam on Pseudomonas aeruginosa have been revealed in different studies. The multiple resistance rate of nosocomial P. aeruginosa strains isolated from intensive care units (ICUs) has been reported as high in many studies. METHODS: In this study, the effects of various combinations of antibiotics (aminoglycoside + beta-lactam and aminoglycoside + quinolone) against 101 multiresistant P. aeruginosa strains which were isolated from the ICUs of three different hospitals in Istanbul were investigated using the E-test method. The combinations for which the highest synergistic effects were determined by the E-test method were also tested with the checkerboard method, i.e. in addition to the E-test method, in 19 of a total of 23 strains. RESULTS: When the synergistic results which were obtained with the combinations of aminoglycoside + beta-lactam were compared with those of the aminoglycoside + quinolone combinations, they were determined to be higher for the two aminoglycosides gentamicin (GM) and tobramycin (TM). We determined the synergistic rates to be 23, 21, 19, 18, 16, 14, 10 and 10% for GM + ceftriaxone (TX), GM + piperacillin (PP), GM + ceftazidime (TZ), TM + PP, TM + TX, TM + TZ, GM + ciprofloxacin (CI) and TM + CI, respectively. The GM + TX combination - for which the highest synergistic effects were determined with the E-test stripes - was also determined as synergistic with the checkerboard method in 19 of a total of 23 strains (23%), and the agreement rate between the two methods was 100% (kappa > 0.7). The highest synergistic effects against strains which were sensitive to both of the antibiotics which constitute the combinations were found for the GM + TX combination, as 50%, whereas for strains which were resistant to both of the antibiotics, this was found for the TM + PP combination, also as 50%. CONCLUSIONS: We consider that the minimal inhibitory concentration values of antibiotics are not sufficient alone in order to constitute a combination for multiresistant strains and it would be advisable to begin a treatment by applying a combination study. The E-test method has been evaluated as a good alternative for combination investigations because of its ease both of application and evaluation and also for its good agreement with the standard checkerboard method.     

Anti-pancreatic antibody in Turkish patients with inflammatory bowel disease and first-degree relatives

AIM: To identify the role of anti-pancreatic antibody (PAB) in the diagnosis of inflammatory bowel diseases (IBD) among Turkish patients, and its frequency in firstdegree relatives.METHODS: PAB and anti-Saccharomyces cerevisiae (ASCA) were examined in serum samples of 214 subjects including patients with Crohn’s disease (CD, n = 64), ulcerative colitis (UC, n = 63), first-degree relatives of patients with CD (n = 25), first-degree relatives of patients with UC (n = 28),and a control group with gastrointestinal symptoms other than (IBD) (n = 34) by indirect immunofluorescence Positivity of PAB and ASCA was compared in terms of Vienna classification, disease activity and medications used.RESULTS: In terms of PAB positivity, no difference was found between patients with CD (14.1%) and UC (7.9%) however, significant difference was observed between patients with CD and subjects in the control group (P < 0.05). No difference was found between patients with CD and their relatives in terms of ASCA positivity, whereas a significant difference was found between other groups (P < 0.001). Compared to ASCA, the sensitivity of the PAB was 19% (7/37), its specificity was 93% (25/27), positive predictive value was 77% (7/9) and negative predictive value was 45% (25/55). ASCA was found with significantly higher prevalence in patients with CD activity index > 150 (P < 0.05).CONCLUSION: PAB is valuable in the diagnosis of IBD rather than CD, but cannot be used alone for diagnostic purposes. PAB is not superior to ASCA in CD diagnosis and in detecting CD among relatives of patients with CD.

Correlations of isokinetic measurements with tendon healing following open repair of rotator cuff tears

The aim of this study was to investigate the correlation of tendon integrity following open cuff repairs with functional and isokinetic strength measurements. Twenty-six shoulders of 25 patients were included in this study. At the final follow-up, 14 repairs (53.8%) were intact and 12 repairs (46.2%) had failed on magnetic resonance imaging (MRI). Mean UCLA score at latest follow-up was 28.5 and mean Constant score was 80.3. Constant scores were found to be significantly low for the failed group. Age was found to be significantly related to failed repair. Fatty infiltration stage in the failed repair group was significantly high, and a strong positive correlation for both groups existed pre and postoperatively. When both groups were compared, the failed group was found to have significantly low measurements at extension and internal rotation. Despite high failure rates, functional results were satisfactory. Increased age and fatty infiltration stage decrease success.     

Bone mineral density in patients with familial Mediterranean fever

This study was carried out to determine lumbar and femoral bone mineral density (BMD) in patients with familial Mediterranean fever (FMF), an autosomal-recessive disease characterized by recurrent episodes of peritonitis, pleuritis, and arthritis, which are usually associated with fever. In patients with FMF and control subjects, erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) were measured. BMD was determined at the lumbar spine (L1–4) and the femoral regions (neck and total) using dual energy X-ray absorptiometry. Twenty-eight FMF patients and 30 control subjects without a history of inflammatory disease participated in our study. The demographic variables, such as age, sex and body mass index were similar between patients and controls (P > 0.05). We found statistically significant difference in ESR and CRP between FMF patients and controls (P < 0.01, P < 0.05 respectively). There was statistically significant difference in lumbar spine, femoral neck, and total femur BMD between FMF patients and control groups (P < 0.001, P < 0.01, P < 0.01 respectively).Our study indicates that lumbar spine and femoral neck and total femur BMD in patients with FMF may be lower than in healthy subjects.     

The effects of molsidomine on hypoxia inducible factor alpha and Sonic hedgehog in testicular ischemia/reperfusion injury in rats

This study was designed to determine the effect of molsidomine (MO), a precursor of nitric oxide (NO) donor, on hypoxia inducible factor alpha (HIF-1α) and Sonic hedgehog (Shh) levels considered to be involved in the development of testes ischemia/reperfusion (I-R) injury. Torsions were created by rotating ipsilateral testes 720° in a clockwise direction for 6 h and 1-h detorsion of the testis was performed. A sham operation was performed in group 1 (control, n = 7). In group 2 (I-R/Untreated, n = 7), following 6 h of unilateral testicular torsion, 1-h detorsion of the testis was performed. No drug was given. In group 3 (I-R/MO), after performing the same surgical procedure as in group 2, a NO donor MO was given at the starting time of reperfusion. In group 4 (I-R/L-NAME), after performing the same surgical procedure as in group 2, L-NAME was given at the starting time of reperfusion. Testes malondialdehyde (MDA) levels were determined as well as examining the testes histologically. Treatment of rats with MO produced a significant reduction in the levels of MDA and histopathological score compared to testes I-R groups. The Sonic hedgehog (Shh) expression in the basement membrane of the tubuli seminiferi, and sertoli and germinal cells in testicular tissue, were greatly increased in the I-R/MO group compared to groups 1, 2 and 4. Additionally, the HIF-1α expression in the interstitial spaces in testicular tissue were greatly increased in the I-R/MO group. The results suggest that MO has a protective effect against ischemia/reperfusion injury in rat testes and may affect Shh and HIF-1α signaling pathway.
