RESUMEN

Baackground: Precancerous lesions are the most commonly cited factor in gastric cancer etiology. The sequence of events in intestinal-type gastric carcinogenesis is considered to be chronic gastritis, atrophy, intestinal metaplasia (IM), dysplasia, and carcinoma, respectively. Early diagnosis and treatment of advanced precursor lesions and gastric cancer is possible by identifying and monitoring patients with such premalignant lesions. Aim: In our study, we aimed to evaluate the long-term follow-up results of intestinal metaplasia in our hospital and the rate of progression to malignancy by comparing these patients with patients who have undergone gastroscopy without a diagnosis of intestinal metaplasia. Material and Method: One hundred and fifty-six followed-up patients out of 700 between the ages of 18 and 85 who were admitted to our hospital between 2009 and 2019, who were diagnosed with IM by pathological examination from biopsy material, and 150 patients who were not diagnosed with IM between 2009 and 2011 were included. The results of the cases were evaluated first retrospectively; then, the patients who were invited for control and underwent endoscopy were evaluated prospectively. IM and control groups were compared in terms of dysplasia and gastric cancer development. In addition, the IM group was compared in terms of 5 and 10 years of follow-up, extensive or local involvement, and complete and incomplete involvement in terms of dysplasia and cancer development. Results: The follow-up period of the patients ranged from 1 to 10 years, and the mean follow-up interval was 4.2 ± 2.8 (min: 1; max: 10) years. Age, gender, and pathology results of the patients were examined in terms of IM type, localization of IM, pathology accompanying IM, and presence of Helicobacter pylori (Hp) infection and compared with the control group. While gastric carcinoma was detected in three of 156 patients in the IM group, gastric carcinoma was not detected in the follow-up of 150 patients in the control group. IM was most common in the antrum. Incomplete IM was detected in 89 patients, and complete IM in 69 patients. While two of the three patients with gastric carcinoma were localized to the antrum, one patient had incomplete-type IM and two patients had complete-type IM, and Hp was positive in two patients. While dysplasia was detected in nine of the patients diagnosed with IM, it was detected in two patients in the control group. A statistically significant difference was found between the IM and control groups in terms of dysplasia positivity (p = 0.037). On the other hand, no statistically significant difference was found between the IM and control groups in terms of age-group, gender, follow-up time group, and Hp positivity (p > 0.05). There was no significant difference between those who were followed up for 5 and 10 years in the IM group in terms of dysplasia and cancer development. Conclusion: Therefore, it is considered that patients with intestinal metaplasia may be followed up at longer intervals, except for patients with race, ethnicity, incomplete type, extensive involvement, and a family history of gastric cancer.

RESUMEN

PURPOSE: To evaluate the relationship between clinical severity and functionality, sleep quality, depression, and quality of life (QoL) in patients with CVI with or without leg ulcers. METHODS: A total of sixty patients with CVI were enrolled in the study. The patients were C2-6 according to the CEAP classification. All the patients were assessed with Venous Clinical Severity Score (VCSS) for clinical severity, Visual Analog Scale (VAS) for pain, right and left lower limb (RLL and LLL) circumference measurements for edema, 6-min-walk test (6-MWT) for functional capacity, Lower Extremity Functional Scale (LEFS) for functionality, Pittsburg Sleep Quality Index (PSQI) for sleep quality, Beck Depression Inventory version I (BDI-I) for depression, and The Quality of Life Questionnaire for Chronic Venous Diseases-20 (CIVIQ-20) for QoL. RESULTS: The mean age of the patients was 45.83 ± 13.25 years, and the mean duration of disease was 8.30 ± 7.42 years. There was a significant association between VCSS and VAS-rest/activity, edema-RLL/LLL, PSQI, BDI-I, LEFS, and CIVIQ-20 in patients without leg ulcers. In addition, a significant association was found between VCSS and VAS-rest/activity and CIVIQ-20 in patients with leg ulcers. CONCLUSION: The current study showed that an association has been found between clinical severity and pain at rest and during activity, edema, sleep quality, depression, lower extremity function, and QoL in patients without ulcers. However, clinical severity has been correlated with only pain at rest and during activity, and QoL in patients with leg ulcers.

RESUMEN

Mature cystic teratoma is the most common ovarian neoplasm. However, mucinous cystadenoma with teratoma has been very rarely reported in literature. This case report, which is very rare, describes a clinical entity not previously reported in literature. A 34-year-old pregnant woman presented in the 23rd gestational week with severe right lower quadrant pain. She was diagnosed with acute abdomen and was then treated surgically. During the surgical intervention, a spontaneously ruptured mass was detected in the right ovary. This was reported histopathologically as a mature cystic teratoma in collision with mucinous cystadenoma. To the best of our knowledge, this case report is the first to have identified a ruptured mature cystic teratoma in collision with mucinous cystadenoma in a pregnant woman.

RESUMEN

Chewing disorders can be seen in children with neuromuscular diseases (NMDs), which may cause swallowing difficulties such as choking, retching and food stuck feeling in the throat. Due to these effects, it is important to determine chewing disorders early with appropriate assessment methods to plan appropriate therapies in NMDs. The aim of this study was to investigate reliability and validity of the Karaduman Chewing Performance Scale (KCPS) in children with NMDs. Age, sex and diagnosis were recorded. Children were asked to chew a standardised biscuit while video-recording. Two physical therapists scored each video according to the KCPS. The correlation between the KCPS scores of 2 therapists was analysed for interobserver reliability. One therapist rescored the recordings after an interval of 2 weeks for intra-observer reliability. The Pediatric Version of the Eating Assessment Tool (PEDI-EAT-10) was used for criterion-based validity. Sixty-eight children with a mean age of 8.34 ± 3.73 (min = 2.5, max = 14.5) years were included, of which 94.1% were male. Karaduman Chewing Performance Scale scores were found to be level 0 in 20 cases, level 1 in 35 cases, level 2 in 12 cases and level 3 in 1 case. A positive, very strong correlation was detected between 2 therapists (r = .93, P < .001) and between 2 examinations of 1 therapist (r = .83, P < .001). A good correlation between the KCPS and PEDI-EAT-10 was detected (r = .62, P < .001). Chewing function, especially food processing phase, deteriorated in children with NMDs. The KCPS could be used as a reliable and valid instrument in determining chewing performance level for children with NMDs.

RESUMEN

Excessive usage of the Internet can negatively affect health and health practices especially among youth. To examine the issue among Turkish students, this study determined the association between high-school students' attitudes towards Internet usage and their health behaviour. The sample (n = 2043) was randomly drawn from all students at two high schools in Turkey: one in Anatolia and one (a vocational school) in Istanbul. Data were collected using the Structured Questionnaire, Attitude Scale towards Internet Usage (ASTIU) and Adolescent Lifestyle Profile (ALP). The mean age of the students was 16.3 years, 77.7% were male and 96.9% used the Internet; mean duration of Internet use was 18.8 h/week. Female students had more positive attitudes towards Internet usage. Mean scores for ASTIU and ALP were 72.58 (SD 17.64) and 111.34 (SD 16.61) respectively, which were average levels. There was a statistically significant but weak overall negative correlation between adolescents' attitudes towards Internet usage and their health behaviour. Our results concur with studies in different cultures which suggest some negative effects, of heavy Internet use.

RESUMEN

BACKGROUND: Postoperative emergency agitation (EA) is a common problem. Dexmedetomidine and remifentanil may be used to prevent this problem. Our primary aim was to compare dexmedetomidine, remifentanil, and placebo with respect to their effectiveness in preventing postoperative EA. MATERIAL AND METHODS: Ninety patients undergoing nasal surgery were randomized into three groups. The dexmedetomidine group (group D, n = 30) received dexmedetomidine infusion at a rate of 0.4 µg kg(-1 ) h(-1); the remifentanil group (group R, n = 30) received remifentanil infusion at a rate of 0.05 µg kg(-1) min(-1) from induction of anesthesia until extubation; and the control group (group S, n = 30) received a volume-matched normal saline infusion as a placebo. Propofol (1.5-2 mg kg(-1)) and fentanyl (1 µg kg(-1)) were used to initiate anesthesia, and desflurane was used to maintain anesthesia. The incidence of agitation, hemodynamic parameters, and recovery characteristics were evaluated during emergence. RESULTS: The incidence of EA was significantly higher in group S (46.7%) compared with groups R and D (3.3 and 20%, respectively; p < 0.001). The lowest incidence of EA was detected in group R (p = 0.046). Residual sedation in the post-anesthesia care unit (PACU) was similar in all groups (p = 0.947). The incidence of nausea or vomiting was significantly lower in group D than in groups R and S (p = 0.043). Administration of analgesics in the PACU was higher in group R than in groups S and D (p = 0.015). CONCLUSION: Anesthetic maintenance with either remifentanil or dexmedetomidine infusion until extubation provided a more smooth and hemodynamically stable emergence, without complications after nasal surgery. While remifentanil was superior to dexmedetomidine with regard to avoiding EA, dexmedetomidine was more effective than remifentanil regarding vomiting and pain.

RESUMEN

OBJECTIVE: The aim of this study was to compare the total medicament doses and recovery profiles of patients for whom Bispectral Analysis (BIS) monitor was used to monitor sedation. STUDY DESIGN: Thirty-four uncooperative paediatric patients aged 3-6 years who attended to the Department of Pediatric Dentistry for dental treatment were enrolled in the study. Patients were randomly divided into 2 groups of 17 patients each. Physiological variables including oxygen saturation, blood pressure and heart rate were recorded. In one group (BIS-monitored group), drugs were administered to maintain patients' BIS values between 60-70, while the other group (Non-BIS-monitored Group) was not monitored using BIS. Data was evaluated by Chi-square, Mann Whitney U, Independent Samples t, Paired Samples t and Wilcoxon signed tests, with a p-value of <0.05 considered to be statistically significant. RESULTS: There was no significant difference in total anesthetic doses, incidence of adverse events or recovery profiles of patients between non- BIS-monitored and BIS-monitored groups (p ≥ 0.05). However, distinct correlation was determined among mean values of UMSS and BIS values (p<0.05). CONCLUSION: BIS represents no advantage over the current commonly accepted methods for monitoring sedation depth in children.

RESUMEN

AIM: The aim of this study was to investigate the effect of different types of anesthesia on stress hormones. MATERIALS AND METHODS: The study was included 60 ASAI-II cases scheduled for major lower extremity surgery. The cases were randomized into 2 groups: The EA group was administered epidural anesthesia and the GA group was administered standard general anesthesia. In order to evaluate the surgical trauma - related stress response, CRP, TSH, cortisol, and fasting blood sugar(FBS) levels were measured preoperatively, 30 min after surgical incision, and 24 h post surgery. RESULTS: Between-group comparisons; Preoperative values were not significantly different between the groups.( P > 0,05) Pulse rate and cortisol values significantly higher in general group at 30 min. ( P < 0,05), and the FBS values were significantly higher in the epidural group at 24 h.( P < 0,05) There were not found differences for other parameters at evaluation times. CONCLUSION: No differences were observed between the two anesthesia methods, in terms of minimizing the stress response due to surgical trauma during major low extremity surgery.

RESUMEN

Multipotent mesenchymal stromal cells (MSC) can be isolated from many tissues, including bone marrow (BM) and placenta (PL). Human placenta can be obtained readily without invasive procedures. There may be differences, however, in differentiation capacity and immunomodulation by MSC isolated from BM or PL. The early pregnancy factor (heat shock protein 10; EPF/Hsp10) is a small protein that exhibits immunomodulatory properties. We compared BM- and PL-MSC, and assessed their efficacy for suppressing T-cell proliferation in vitro and the role of EPF/Hsp10 in this process. PL-MSC were collected from whole placenta after removal of the amniotic and chorionic membranes followed by serial enzymatic digestions. The PL-MSC were compared to BM-MSC, obtained from healthy donors. Differentiation capacity, cytokine secretion, expression and secretion of immunomodulatory molecules, immunophenotype and real time proliferation were assessed using cytokine arrays, ELISA assays, flow cytometry, immunohistochemical staining and western blotting. Whereas BM-MSC consisted of a homogeneous cell population with strong expression of mesenchymal markers, PL-MSC consisted of a mixed population of cells with variable CD73, CD90 and CD105 expression. PL-MSC exhibited a significantly greater proliferation rate than BM-MSC. The presence of both stem cells and more mature cells in the PL-MSC cultures resulted in decreased differentiation capacity and reduced efficacy of immune suppression in co-cultures with T-cells. Although robust intracellular expression of EPF/Hsp10 in both BM- and PL-MSC was observed, secretion of the protein in response to immune activating stimuli remained below detectable levels. Secretion of pro-inflammatory cytokines was significantly greater in BM-MSC than PL-MSC, whereas no difference was observed in the secretion of hematopoiesis supporting growth factors. Development of culture methods for isolation of pure populations of PL-MSC may improve the quality of the product and reproducibility of results.

RESUMEN

OBJECTIVE: The aim of this study was to evaluate the possible variations in antioxidant enzymes, lipid peroxidation and erythrocyte deformability in experimentally induced osteoporosis in female rats and to assess the effects of vitamin C supplementation on those variations. MATERIAL: A total of 20 female Wistar Albino Rats were randomized into the three groups as controls (Group C, n = 6), ovariectomized rats (Group O, n = 7) and ovariectomized rats receiving vitamin C supplementation (Group OVC, n = 7). After the surgical procedure of ovariectomy, group OVC received 1 g ascorbic acid in 500 mL water daily. After 100 days following the ovariectomy, bone mineral density (BMD) was measured by using dual-energy X-ray absorptiometry. RESULTS: BMD was significantly lower in the group O than in the group C (p = 0.015), whereas it was significantly higher in the group OVC than in the group O (p = 0.003). MDA activity was significantly higher in the group O than in the group C (p = 0.032), whereas it was significantly lower in the group OVC than in the group O (p = 0.025). SOD activity was significantly higher in the group O than in the group C (p = 0.032). Erythrocyte deformability was significantly higher in the group O than in the group C and OVC (p = 0.008, p = 0.021, respectively). CONCLUSION: Erythrocyte deformability may show negative variations, suggesting a causative role in disruption of blood flow and tissue perfusion, which also negatively affect bone metabolism. Vitamin C supplementation seems to reverse those negative effects of variations in erythrocyte deformability. However, our preliminary results should be confirmed in more experimental studies and clinical trials (Tab. 3, Ref. 28).

RESUMEN

AIM: This study aims to evaluate the prevalence and clinical characteristics of neurological complications in patients with newly diagnosed neuroblastic tumors (NT). PATIENTS AND METHOD: Hospital file search was performed in patients with NT, and neurological complications, clinical, and treatment features were analyzed. RESULTS: Out of 523 patients with NT, 19 patients had Horner's syndrome, 9 patients had opsoclonus-myoclonus-ataxia syndrome (OMA), 11 patients had central nervous system (CNS) involvement, and 49 patients had spinal cord compression (SCC) at diagnosis. During follow-up, seven more patients had CNS metastases. Survival rates were poor in patients with CNS involvement; all died at a median of 7.9 months after diagnosis. The neurological symptoms and signs of patients with SCC were mild, moderate, and severe in 13, 9, and 22 patients, respectively. Sphincter deficiency and sensory loss were diagnosed in 52.3% and 43.2% of patients. The neurological deficits of 11/17 patients who had symptoms less than 4 weeks were completely resolved or improved. The incidence of sequelae after laminectomy, radiotherapy, and chemotherapy were 46.2%, 66.6%, and 13.6%, respectively. CONCLUSION: The prevalence rates of Horner's syndrome, OMA, CNS metastasis, and SCC were found to be 3.6%, 1.8%, 2.2%, and 9.4%, respectively. Metastasis to the CNS indicated a very poor prognosis. No differences in neurological improvement in patients with SCC were found between those treated with radiotherapy, laminectomy, or chemotherapy alone, but laminectomy and radiotherapy caused significant late sequelae. Early diagnosis and proper management is critical to avoid long-term sequelae in patients with SCC.

RESUMEN

The objective of this study was to evaluate urinary vanillylmandellic acid (VMA) as a marker for prognosis and progression of neuroblastoma. A retrospective file search of 444 patients during 33 years was performed and correlation of VMA with clinical prognostic parameters and outcome was evaluated. Event-free survivals (EFS) were 33.5% and 21% (P = .04) and overall survival (OS) were 36.6% and 25.8% (P = .1) for all patients with normal/negative and increased/positive VMA. EFS and OS were higher in VMA(-) pelvic (P = .03) and thoracic and neck (P = .04) tumors, compared to their VMA(+) counterparts. Survival was not different in patients with abdominal primaries according to VMA status. Positive urinary VMA prevalence was low in localized disease and high in disseminated disease (P < .001). In disseminated disease, 10-year EFS was higher in VMA(+) patients than VMA(-) patients (16%, 9.5%, P = .054). Two-year OS was higher in VMA-positive patients with stage 4 disease (20.6% and 7%, P = .04). The patients with VMA(+) progressive disease died later than those with VMA(-) tumors (P = .047). These results show that increased urinary VMA predicts poor outcome for patients with favorable tumor sites. Urinary VMA can be useful risk determinant in combination with other biological determinants to predict prognosis of patients with localized neck, thoracic or pelvic tumors. The relationship of positive or high urinary VMA and survival were inversely correlated in disseminated disease and in patients with progressive disease. In high-risk patients, negative spot test or normal level of urinary VMA at diagnosis might be used for identification of a group of patients with more favorable prognosis.

RESUMEN

AIM: To standardize diagnosis and treatment of childhood Wilms tumor (WT) in Turkey. METHODS AND PATIENTS: Between 1998 and 2006, WT patients were registered from 19 centers. Patients <16 years with unilateral WT whose treatment started in first postoperative 3 weeks were included. Treatments were stage I favorable (FH) and unfavorable histology (UH) patients, VCR + Act-D; stage IIA FH, VCR + Act-D; stage IIB FH, VCR + Act-D + radiotherapy (RT); stage III-IV FH, VCR + Act-D + adriamycin (ADR) + RT; stages II-IV UH tumors, VCR + Act-D + ADR + etoposide + RT. RESULTS: 165/254 registered cases were eligible (bilateral, 5.9%) [median age 3.0 years; M/F: 0.99; 50/165 cases < or =2 years]. 9.7% cases had UH tumors. Disease stages were stage I 23.6%; IIA 36.4%; IIB 5.5%; III 22.4%; IV 12.1%. Cases >2 years had significantly more advanced disease. 1/11 cases with recurrent disease died; 2/165 had progressive disease, 2/165 had secondary cancers, and all 4 died. In all cases 4-year OS and EFS were 92.8 and 86.5%, respectively. Both OS and EFS were significantly worse in stage IV. CONCLUSIONS: Despite problems in patient management and follow-up, treatment results were encouraging in this first national experience with a multicentric study in pediatric oncology. Revisions and modifications are planned to further improve results and minimize short- and long-term side effects.

RESUMEN

The posttranslational modification ADP-ribosylation is involved in many cellular processes, with distinct roles for poly- and mono(ADP-ribosyl)ation (PAR- and MARylation, respectively). Reversibility of intracellular MARylation was demonstrated with the discovery of MACROD1, MACROD2 and TARG1, three macrodomain-containing enzymes capable of reversing MARylation of proteins and RNA. While the three enzymes have identical activities in vitro, their roles in cells are unclear and published data are partially contradictory, possibly due to a lack of validated reagents. We developed monoclonal antibodies to study these proteins and analysed their tissue distribution and intracellular localisation. MACROD1 is most prevalent in mitochondria of skeletal muscle, MACROD2 localises to nucleo- and cytoplasm and is found so far only in neuroblastoma cells, whereas the more ubiquitously expressed TARG1 is present in nucleoplasm, nucleolus and stress granules. Loss of MACROD1 or loss of TARG1 leads to disruption of mitochondrial or nucleolar morphology, respectively, hinting at their importance for these organelles. To start elucidating the underlying mechanisms, we have mapped their interactomes using BioID. The cellular localisation of interactors supports the mitochondrial, nucleolar and stress granule localisation of MACROD1 and TARG1, respectively. Gene ontology analysis suggests an involvement of MACROD1 and TARG1 in RNA metabolism in their respective compartments. The detailed description of the hydrolases' expression, localisation and interactome presented here provides a solid basis for future work addressing their physiological function in more detail.

RESUMEN

OBJECTIVE: To assess the predictive value of undulant alpha fetoprotein (AFP) course in recurrence of germ cell tumors (GCT). PATIENTS/METHOD: A retrospective file search of 491 patients with GCT was performed and 18 patients who had an undulant course of AFP levels (increased and spontaneously decreased) without any demonstrable tumor on radiological images were selected for the study. RESULTS: The median age of the 10 boys and 8 girls was 2 years (1.1-16 years). All the patients were disease-free for a median of 16.2 months (8.4-132 months). At follow-up, radiologically proven tumor recurrences were diagnosed in 8 patients in median 12.2 +/- 3.2 months from the initial diagnosis (8.4-18.2 months) and 7.4 +/- 2.2 months from the last normal level of AFP (5.0-11.2 months). The mean peak AFP values within the first 90 days were 24 +/- 38.1 ng/mL and 11.1 +/- 10.9 ng/mL in patients who did and did not have recurrent disease, respectively (p = .0051). The patients whose AFP levels were higher than 10 ng/mL were likely to have recurrent disease (p = .02). CONCLUSION: Without a demonstrable tumor, the small amplitude undulations may only require careful follow-up. However, it should be kept in mind that despite the decrease in AFP levels, there still might be a risk of recurrence, especially in patients who have greater amplitude undulations.

RESUMEN

Bedük Esen ÇS, Gültekin M, Aydin GB, Akyüz C, Karli Oguz K, Orhan D, Cengiz M, Gürkaynak M, Yildiz F. Ewing sarcoma in an infant and review of the literature. Turk J Pediatr 2019; 61: 760-764. Ewing sarcoma (ES) is a rare tumor in infants and prognosis is controversial. There are no standard recommendations for treatment in such very young patients. Generally, radiotherapy (RT) is not a part of treatment in infants due to the risk of severe late side effects. In this case report, we report a 7-month-old boy with diagnosis of left mastoid bone ES with lung metastases at diagnosis, showing a rapidly fatal outcome despite aggressive systemic chemotherapy and RT without surgery.

RESUMEN

OBJECTIVE: We aimed to determine whether the combination of a CHA2DS2-VASc score (C: Congestive Heart Failure, H: Hypertension, A2: Age ≥ 75 years, D: Diabetes mellitus, S: Stroke history, V: Vascular disease, A: Age ≥ 65 years, Sc: Sex category) and pre-percutaneous coronary intervention (PCI) thrombus load score was more sensitive at detecting the no-reflow phenomenon compared to the CHA2DS2-VASc score alone or to the thrombus load score alone in patients with acute ST-elevation myocardial infarction (STEMI) who had underwent primary PCI (PPCI). PATIENTS AND METHODS: 497 patients with acute STEMIs were divided into two groups: no-reflow group (n: 194) and control group (n: 303). The Thrombolysis In Myocardial Infarction (TIMI) flow grading and Myocardial Blush Grade (MBG) were used together to define angiographic no-reflow as TIMI flow < 3 (with any MBG grade) or TIMI flow 3 with MBG 0 or 1. Successful reperfusion was defined as TIMI flow 3 with MBG 2 or 3. RESULTS: CHA2DS2-VASc score was significantly higher in the no-reflow group than in the control group (2 [1-4] vs. 1 [0-3], p < 0.001]. Compared with the control group, the no-reflow group had a higher pre-PCI thrombus score (5 [4-5] vs. 4 [3-5], p = 0.001). Compared with the CHA2DS2-VASc score alone, the combined use of the pre-PCI thrombus score and the CHA2DS2-VASc score was associated with significant improvements in the ability to predict no-reflow (AUC) (0.65 vs. 0.60, p < 0.05). The addition of the pre-PCI thrombus score to the CHA2DS2-VASc score was related to a significant net reclassification improvement of 6.7% (p = 0.047) and an integrated discrimination improvement of 0.036 (p < 0.05). CONCLUSIONS: We have found that the combination of a CHA2DS2-VASc score and a pre-PCI thrombus load score was more sensitive in detecting the no-reflow phenomenon than only a CHA2DS2-VASc score in patients who underwent PPCIs for STEMIs.

RESUMEN

This article describes the emergence of resistance and predictors of fatality for 1556 cases of healthcare-associated Gram-negative bloodstream infection in 2014 and 2015. The colistin resistance rate in Klebsiella pneumoniae was 16.1%, compared with 6% in 2013. In total, 660 (42.4%) cases were fatal. The highest fatality rate was among patients with Acinetobacter baumannii bacteraemia (58%), followed by Pseudomonas aeruginosa (45%), Klebsiella pneumoniae (41%), Enterobacter cloacae (32%) and Escherichia coli (28%). On multi-variate analysis, the minimum inhibitory concentrations for carbapenems [odds ratio (OR) 1.02, 95% confidence interval (CI) 1.01-1.04; P = 0.002] and colistin (OR 1.1, 95% CI 1.03-1.17; P = 0.001) were found to be significantly associated with fatality.

RESUMEN

AIM: The aim of the study was the electrophysiological evaluation of the cremasteric reflex after experimental testicular torsion. MATERIAL AND METHODS: Ten male Wistar rats were enrolled into the study. Genitofemoral nerve (GFN) motor conduction and cremasteric reflex (CR) responses were evaluated electrophysiologically after being subjected to anesthesia with intramuscular ketamin hydrochloride. Testicular torsion was performed by rotating the right testicle 720 degrees in a clockwise direction from a midscrotal incision. Electrophysiological evaluations were repeated in the early (30 minutes) and late (90 minutes) periods of testicular torsion. Subsequently, detorsion of the testicles was performed and electrophysiological recordings were completed after 60 minutes of detorsion. The CR was also evaluated clinically before each electrophysiological evaluation. The latency and duration of GFN motor conduction and CR responses was compared for base, early torsion, late torsion and detorsion recordings. Friedman's test for repeated measurements was used for statistical analysis. RESULTS: The CR, which was detected clinically before torsion and after detorsion, was not detected during torsion. When base, early torsion, late torsion and detorsion recordings were compared, there was no statistical difference with respect to both latency and duration of GFN motor conduction and CR responses (p > 0.05). CONCLUSION: Although CR was not detected clinically during testicular torsion, the electrophysiological parameters of the reflex did not differ in the early and late periods of torsion in rats. The GFN motor conduction parameters also showed no differences. In conclusion, the absence of the CR after testicular torsion could not be confirmed by electrophysiological studies.
