The ganglioneuroblastoma are rare lesions with widespread neuronal differentiation that have been classified as intermediate stages between neuroblastoma and ganglioneuroma. To identify overall chromosome aberrations in ganglioneuroblastoma, we performed comparative genomic hybridization. All of the five tumor samples were found to exhibit multiple gains involving different chromosomal regions. Chromosomal gains displayed by chromosomes and chromosome loci were 2p25 approximately pter (60%), 5p15.1 approximately p15.3 (60%), 7 (60%), 13q22 approximately q31 (60%), and 22 (60%), which were detected as minimal common regions in all five tumor samples. Chromosome 22 gain, which had not been reported in neuronal tumors before, and novel site 13q22 approximately q31 may be considered to play an important role in progression and differentiation of ganglioneuroblastoma. 相似文献

Ischaemic priapism is the most common form of priapism and requires urgent treatment. In this study, we evaluated the effectiveness of the caverno-dorsal vein shunt on resolution of ischaemic priapism and on the post-operative long-term erectile function in patients presenting with priapism. The study included 10 patients admitted to our hospital for priapism between 2010 and 2018. The median age of the patients was 31 (24–66) years. The median priapism time was 13.5 (7–38) hours. The blood gas measurements were taken from the corpus cavernosum, and the drainage of the corpus cavernosum was performed as an emergency intervention. Then, the corpus cavernosum was irrigated with 0.01% adrenaline 5 times in 20-min intervals. The caverno-dorsal vein shunt procedure was performed in cases without regression of priapism. Two months after, the operation shunt was closed. Detumescence occurred in all patients. Eight of 10 patients maintained their erectile function. In 2 patients, severe erectile dysfunction occurred at post-operative 2 months following a priapism attack and penile prosthesis implantation was performed in these 2 patients. Our study showed that caverno-dorsal vein shunt procedure is effective in providing detumescence and maintaining potency in cases with ischaemic priapism. In our opinion, caverno-dorsal vein shunt can be considered as the first treatment of choice for refractory low-flow priapism. 相似文献

Background: To characterize the methicillin-resistant Staphylococcus aureus (MRSA) clones present in Istanbul, 102 MRSA isolates collected during a 5-year period at the Istanbul Medical Faculty Hospital were characterized using microarray analysis and phenotypic resistance profiles.Methods: Resistance to methicillin was detected with a cefoxitin disk diffusion assay and confirmed with a MRSA-agar and MRSA detection kit. Antimicrobial susceptibility testing was performed by a disk diffusion assay and interpreted according to the 2012 guidelines of the Antibiogram Committee of the French Society for Microbiology. Decreased susceptibility to glycopeptides was confirmed using the population analysis profile-area under the curve (PAP-AUC) method. The presence of the mecA gene was detected by polymerase chain reaction. Bacterial DNA was extracted according to the manufacturer''s recommended protocol using commercial extraction kits. Strains were extensively characterized using the DNA microarray.Results: Isolates were grouped into six clonal complexes. The most frequently detected clone was the Vienna/Hungarian/Brazilian clone (ST239-MRSA-III), which accounted for 53.9% of the isolates. These isolates were resistant to multiple antibiotics, particularly penicillin, tetracycline, rifampicin, kanamycin, tobramycin, gentamicin, levofloxacin, erythromycin, lincomycin and fosfomycin. Furthermore, three isolates were detected by population analysis profile as heterogeneous vancomycin-intermediate S. aureus (hVISA). The UK-EMRSA-15 clone (ST22-MRSA-IV PVL negative) was detected in 9.8% of the isolates and was mainly susceptible to all anti-staphylococcal antibiotics. Seven isolates (6.9%) were positive for PVL genes and were assigned to the CC80-MRSA-IV clone (European CA-MRSA clone, three isolates), ST8-MRSA-IV clone (USA300 clone, two isolates, one ACME-positive) or ST22-MRSA-IV clone (“Regensburg EMRSA” clone, two isolates). All other clones were detected in one to six isolates and corresponded to well-known clones (e.g., Pediatric clone, Dublin EMRSA clone, WA MRSA-54/63, WA MRSA-1/57).Conclusions: This work highlighted both the high prevalence of ST239-MRSA-III clone and the large diversity of the other MRSA clones detected in a university hospital in Istanbul. 相似文献

We investigated the effects of long- and short-term interdisciplinary treatment approaches for reducing symptoms and improving health-related quality of life (HRQoL) and physical functions of patients with fibromyalgia and compared the effects of two different interdisciplinary treatment approaches. We conducted a prospective, randomized, controlled trial involving 66 women with fibromyalgia eligible for the study at a university hospital setting. The patients were randomized into three groups (allocation ratio 1:1:1) using a computer-generated random numbers: a long-term interdisciplinary treatment group (LG, n = 22) that participated in 10 sessions (3-h once-weekly session for 10 weeks) of cognitive behavioral therapy (CBT) together with exercise training and other fibromyalgia related educational programs (two full days); a short-term interdisciplinary treatment group (SG, n = 22) that received two full days of educational, exercise, and CBT programs; and a control group (CG, n = 22). The patients were evaluated at baseline and 6 months after treatment using the visual analog scale (pain, fatigue, and sleep), Fibromyalgia Impact Questionnaire, Beck Depression Inventory, Short Form-36, tender point numbers, and pressure algometry as primary outcomes. The statistical analysis was confined to the ‘per-protocol’ set. No blinding was performed. The number of patients analyzed was 21 in the LG, 19 in the SG, and 19 in the CG. The intensity of pain (p < 0.001), severity of fatigue (p = 0.048), number of tender points (p = 0.002), and pressure pain threshold (p = 0.012) decreased significantly in both the LG and SG groups compared with controls. Moreover, physical functions (p = 0.017) and physical components of the HRQoL (p = 0.036) improved significantly in the intervention groups compared with the controls. However, there was no significant difference between intervention groups and the control group at the end of study in terms of quality of sleep (p = 0.055), severity of depressive symptoms (p = 0.696), and mental components of the HRQoL (p = 0.229). Finally, with the exception of the severity of fatigue and physical components of the HRQoL, there was no obvious significant difference between the efficacies of the two treatment approaches when compared with controls; the long-term treatment was found more effective in reducing pain than the short-term. Both, long- and short-term interdisciplinary treatments were effective in reducing the severity of some symptoms and disease activity in patients with fibromyalgia. The short-term program well meets the needs of women with fibromyalgia particularly in relation to pain and health status as measured using FIQ; however, a long-term program may be beneficial in reducing fatigue and improving physical function to a higher extent. 相似文献

The study of the haemocompatibility of nanomaterials that could be in contact with blood (e.g. nanoparticle (NP)-based drug-delivery system) is of major importance. The primary objective of this study was to compare the ability of six platelet functional tests to assess the impact of NPs on platelet function. The secondary objective was to determine an accurate and reliable screening test to measure the potential impact of NPs on primary haemostasis whatever their physicochemical properties. Four types of carbon NPs (carbon black, fullerenes, single-walled carbon nanotubes and multi-walled carbon nanotubes) were investigated on six platelet function tests: light transmission aggregometry, whole-blood impedance aggregometry, platelet function analyser-100 (PFA-100®) and Cone-and-Plate(let) analyser (Impact-R®), transmission- and field emission gun scanning electron microscopy (FEG-SEM). We considered that Impact-R® supported by FEG-SEM is the reference method to investigate the potential impact of NPs on platelet function. 相似文献

The objective of this study was to compare the MRI findings of wrists in patients diagnosed with CTS with those of the healthy controls, and to evaluate the correlation between the MRI differences and the electrophysiological findings in the patient group. This study involved 55 wrists, 30 of which were clinically and electrophysiologically diagnosed with CTS and 25 healthy controls. These 55 wrists were evaluated electrophysiologically, and in terms of median nerve diameter, ratio of median nerve diameter at psiform bone level to distal radio-ulnar joint level, the flexor retinaculum bulging ratio and the median nerve intensity by MRI. When the patient group, which were clinically and electrophysiologically diagnosed with CTS, and the healthy control group were compared, a significant difference (p < 0.001) was observed between the two in terms of median nerve diameters (at psiform bone level: 8.47 +/- 1.41mm and 2.91 +/- 1.01 mm, distal radio-ulnar joint level: 4.04 +/- 1.06 mm and 2.42 +/- 0.95 mm), ratio of median nerve diameter at psiform bone level to distal radio-ulnar joint level (2.17 +/- 0.54 and 1.25 +/- 0.12), their flexor retinaculum bulging ratios (26.21 +/- 5.98% and 7.27 +/- 4.53%) and their median nerve intensities. In the patient group, no significant correlation between MRI and the electrophysiological findings was found (p > 0.05). According to the data obtained from the study, we believe that the MRI examination of structural changes that occur in the carpal tunnel, neighboring structures and the median nerve would be useful in the diagnosis of CTS, especially in cases with suspected clinical and electrophysiological diagnosis. 相似文献

The purpose of this study was to investigate the associations of tooth loss with skeletal bone mass, years since menopause,
educational level, current smoking status, dietary calcium intake, and number of pregnancies in postmenopausal osteoporotic
women in Turkey. The study population consisted of 1171 postmenopausal women aged 40–86 years (mean age, 61.19 ± 7.28 years).
A detailed history was obtained from all women, including relevant lifestyle parameters, risk factors, and measurements of
weight and height. Women were separated into three groups according to the number of teeth remaining as group 1 (edentulous,
457 women), group 2 (10 or fewer teeth, 232 women), and group 3 (more than 10 teeth remaining, 482 women). There was no significant
difference among the three groups in mean age and menopausal age (P < 0.05). Body mass index of group 1 was significantly higher than that of group 2 (P < 0.01). Educational level was significantly different between three groups: groups 1 and 2 (P < 0.001), groups 1 and 3 (P < 0.0001), and groups 2 and 3 (P < 0.001). Educational level was lowest in group 1 and highest in group 3. Despite a low ratio of cigarette smoking in general,
a smoking habit was most prevalent in group 3 and least in group 2. The ratio of women receiving adequate calcium was significantly
lower in group 1 than in other groups (P < 0.001); mean calcium intake was similar in all groups. The number of pregnancies was significantly higher in group 1 than
in other groups (P < 0.001). Lumbar bone mineral density (BMD) of group 1 was significantly lower than that of groups 2 and 3 (P < 0.001). Although no significant difference was found between groups 1 and 3, femoral neck BMD of group 2 was less than in
others, and differences between groups 1 and 2 and between groups 2 and 3 (P < 0.001) were significant. Lumbar bone mineral content (BMC) of group 1 was significantly lower than that of groups 2 and
3 (P < 0.001), and lumbar BMC in group 2 was significantly higher than in group 3 (P < 0.05). Femoral neck BMC in group 1 was significantly higher than in groups 2 and 3 (P < 0.001). In conclusion, lumbar BMD and BMC in the edentulous group were significantly lower, whereas femoral neck BMD and
BMC were significantly higher in edentulous group compared with the others. Our findings indicated that improvement in lifestyle
factors and nutritional strategies for the treatment and prevention of osteoporosis may have additional benefit in reducing
tooth loss.

OBJECTIVE: To investigate sympathetic nervous system functions in patients with acute and chronic phase of stroke by measuring sympathetic skin reflex (SSR) and the relationship between sympathetic dysfunction and motor function capacity. DESIGN: Cross-sectional, case-control study. SETTING: A physical medicine and rehabilitation department in a research hospital of a university referral center in Turkey. PARTICIPANTS: Fifty-six patients with stroke-13 in the acute phase and 43 in the chronic phase-and 42 age- and sex-matched healthy volunteers were included. INTERVENTION: SSR was recorded with electric stimulation of the bilateral median nerves. MAIN OUTCOME MEASURES: SSR was recorded to assess sympathetic reflex activity in patients in the acute and chronic phase of stroke and in controls. Motor functions was classified using the Brunnstrom stages. RESULTS: The mean SSR latency in the acute phase was significantly prolonged and the amplitudes were decreased compared with controls. In the chronic phase, the mean amplitudes were significantly attenuated compared with controls, whereas the mean latency did not change. The mean latency of SSR in patients in Brunnstrom groups 1 and 2 was longer, and the mean amplitude was smaller than in controls (P<.05). The mean amplitude was significantly reduced in patients classified as Brunnstrom groups 3 and 4 compared with controls (P<.05), but the mean latency was not affected. CONCLUSIONS: Depression of sympathetic reflex activity was more prominent in the acute phase of stroke and was associated with moderate or highly limited motor function capacity. Improvement of motor dysfunction may parallel recovery of sympathetic reflex activity. 相似文献

Delftia acidovorans is an aerobic, nonfermenting Gram-negative bacillus. It is usually a nonpathogenic environmental organism and is rarely clinically significant. Although D acidovorans infection most commonly occurs in hospitalized or immunocompromised patients, there are also several reports documenting the infection in immunocompetent patients. The present article describes a B cell lymphoblastic leukemia patient with D acidovorans pneumonia who was successfully treated with antibiotic therapy. The present report indicates that unusual pathogens may be clinically significant in both immunocompromised and immunocompetent patients. D acidovorans is often resistant to aminoglycosides; therefore, rapid detection of this microorganism is important. 相似文献
