The First Identification of Encephalitozoon cuniculi Infection in an Animal Care Worker in Turkey

Background:

As a zoonotic pathogen, Encephalitozoon cuniculi is a cause of serious disease in animals and people. The present study was to evaluate the health status examination of this seropositive animal care worker in our previous study.

Methods:

Blood samples were taken from five workers. CIA test was applied to detect antibodies against E. cuniculi in blood serum. The indirect immunofluorescence antibody test was used as confirmation test. Seropositive worker had a complete medical examination.

Results:

Only one worker was found to be seropositive according to the results of the serological test. Sera positive to E. cuniculi was confirmed with IFAT and spores were detected in the urine sample of the worker. The worker was treated with albendazole.

Conclusion:

Rabbits should be examined routinely for the presence of anti-E. cuniculi antibody. People working with laboratory animal should avoid contact with urine and faeces of infected or pay attention to personal hygiene.     

Bone marrow involvement in small cell lung cancer: Prognostic significance and correlation with hematological and biochemical parameters

The more metastatic sites and bone marrow metastasis in small cell lung cancer (SCLC), the worse the prognosis. Diagnosing the bone marrow invasion at the beginning of the therapy is important for determining of the prognosis and planning the treatment. Abnormalities of some blood parameters may help to estimate the extent of bone marrow invasion by cancer cells. In this retrospective review, the changes in routine laboratory tests that may indicate bone marrow invasion, the predictive values of these tests, and the prognostic importance of bone marrow invasion were evaluated in SCLC patients who were being followed up according to a protocol. One hundred and forty‐four patients with SCLC were enrolled in this study. Retrospectively, it was evaluated that 25 (17.4%) of the patients had bone marrow metastasis. According to univariate analysis, there was a significant difference between hemoglobin, white blood cell count, platelet count, lactate dehydrogenase, alkaline phosphatase and uric acid of the patients with and without bone marrow involvement. Among the biochemical parameters, the elevated LDH and AP had the highest sensitivity and specificity as indicators of bone marrow invasion (0.80–0.82 and 0.84–0.78, respectively). The median overall survival of extensive‐stage disease with and without bone marrow metastasis were 4.0 ± 1.0 months (95% CI 2.2–5.7) and 7.0 ± 1.2 months (95% CI 4.7–9.3), respectively (P = 0.03). Bone marrow metastasis was found to be an indicator of a bad prognosis. Bone marrow biopsy, that is an invasive procedure, can be performed on selected patients who have changes of routine laboratory tests suggesting bone marrow invasion.     

Twenty-four-hour Variations in the Effect of Nitrodilators in Rat Aorta: Lack of Influence of the Endothelium

Time-dependent variations of the vasodilator effects of sodium nitroprusside and glyceryl trinitrate on isolated smooth muscle have been studied on rings of rat thoracic aorta, both endothelium-intact and endothelium-denuded. For most of the concentrations of sodium nitroprusside used the induced relaxations were significantly dependent on the time the tissues were obtained. However, significant temporal differences were obtained for glyceryl trinitrate-induced relaxations at lower concentrations only for both endothelium-intact and endothelium-denuded preparations. EC50 values of sodium nitroprusside and glyceryl trinitrate (i.e. the concentrations inducing half the maximum response) were also significantly different and they had quite similar rhythmic features both in endothelium-intact and in endothelium-denuded preparations. These results clearly show that the in-vitro sensitivity of rat thoracic aorta to nitrodilator agents varies over a 24-h period and thus depends on when the animals were killed; the presence of endothelium does not change the rhythm of nitrodilator activity. These variations might be a result of circadian rhythm in the guanylate cyclase-cGMP system which mediates responses to nitrodilator agents.     

Bilateral disruption of corpus cavernosum with complete urethral rupture

Penile fracture is a relatively rare condition. We report an unusual case of the bilateral disruption of the corpus cavernosum with complete urethral rupture resulting from blunt trauma during sexual intercourse. The subject underwent emergency surgery with preservation of erectile and voiding functions in the follow-up.     

The effect of being overweight on survival in patients with gastric cancer undergoing adjuvant chemoradiotherapy

EROGLU C., ORHAN O., KARACA H., UNAL D., DIKILITAS M., OZKAN M. & KAPLAN B. (2013) European Journal of Cancer Care 22 , 133–140 The effect of being overweight on survival in patients with gastric cancer undergoing adjuvant chemoradiotherapy The aim of this study was to examine the effect of being overweight on survival in patients with gastric cancer undergoing adjuvant chemoradiotherapy and chemotherapy. In this study 152 patients were evaluated. Radiotherapy dose was 45 Gy given in 5 weeks. 5-FU 425 mg/m² and folinic acid 20 mg/m² were administered weekly during the radiotherapy and four cycles with 4-week intervals as consolidation chemotherapy after radiotherapy. Patients were assigned into two groups according to their body mass index: overweight (body mass index ≥25 kg/m²) and normal weight (body mass index <25.0 kg/m²). The median overall survival was 39 months vs. 18 months and median disease-free survival was 27 months vs. 13 months in the overweight and normal-weight groups respectively (P= 0.004 and P= 0.006 respectively). The 5-year survival was better in the patients with overweight than those with normal weight (42% vs. 17%; P= 0.004). The overall survival was significantly better with being overweight and early pathological stage (P= 0.016 and P= 0001 respectively). Overall survival, disease-free survival and long-term survival in patients with gastric cancer undergoing adjuvant treatment were better in overweight than normal-weight patients. Moreover, it was shown that body mass index and pathological stage were associated to survival and prognosis.     

Prediction of Head‐Up Tilt Test Result: Is it Possible?

Background: The determination of early, accurate, predictive criteria for a positive result would permit a reduction in the duration of the head‐up tilt testing (HUTT). Previous studies propounded that existence of early sympathetic overreactivity (rapid and sustained increase in heart rate) during HUTT predicts positive result. However, the exact value of this variable is unknown. We analyzed the early heart rate (HR) responses to HUTT and evaluated their ability to predict HUTT result. Methods: Consecutive patients referred to the syncope unit of our center for recurrent unexplained syncope were studied. Results: We studied 189 consecutive patients and 67 (35%) patients had a negative HUTT; 122 (65%) patients had a positive HUTT. The early HR increase was defined as the maximum HR during the first 10 minutes of tilting minus the resting HR before tilting. The receiver–operator curves (ROCs) show the overall performance of the HR changes for predicting the HUTT result. For all variables, area under the ROC curve (AUC) was nearly equivalent to 0.50 and early HR increase was not a predictor of the negative result of HUTT (AUC = 0.546). Also there was no any significant correlation between the magnitude of early HR increase and patient age (r =?0.03, P = 0.76). Conclusions: The results suggest that the early increase in HR during the first 10 minutes of the HUTT may not be a useful parameter for predicting the test result. Many factors, such as late exaggeration in sympathetic activity during HUTT and age‐dependent reduction in baroreflex sensitivity, may attenuate the predictive value of early HR increase.

Testis sparing surgery for the treatment of a sequential bilateral testicular germ cell tumor

Standard therapy of sequential bilateral testis cancer is generally considered to be orchiectomy. We present a case of sequential bilateral testicular germ cell tumor treated with testis sparing surgery. The patient was disease free 50 months after surgery without local recurrence or distant metastases. Testis sparing surgery provides a better quality of life and may be considered a safe, feasible alternative in the treatment of carefully selected patients with bilateral testicular germ cell tumor.     

Human epidermal growth factor receptor 2 oncoprotein expression in breast cancer patients from central Anatolia, Turkey

Aim:   Human epidermal growth factor receptor 2 (HER2) overexpression is associated with poor prognosis and the frequency of HER2 positivity in breast cancer patients varies among different regions of the world. We studied HER2 expression in Turkish breast cancer patients.
Methods:   HER 2 expression was evaluated immunohistochemically in 107 breast cancer patients. HER2 expression was reported as negative or positive (3+) according to cellular membrane staining characteristics. The frequency of HER2 overexpression, distribution according to clinical characteristics, effect on survival and effect of chemotherapy on survival in relation to HER2 overexpression was evaluated.
Results:   The median age of patients was 49 years (range 27–76). HER2 was 3+ in 34 patients (31.8%). There was no significant difference in age, menopausal status, histopathology, lymph node involvement, stage and estrogen and/or progesterone receptor positivity in relation to HER2 expression. Forty-three patients (40.2%) relapsed and 21 patients (19.6%) died during the follow-up period. There was no significant difference in the relapse rate, distribution of relapse sites and death rate in relation to HER2 expression. The 3- and 5-year disease free survival rates were 67.1 and 40.5%, and the overall survival rates were 87.5 and 66.1%, respectively. Survival rate and calculated survival time were relatively shorter in HER2 3+ patients than in non-HER2 3+ patients, but these differences were not statistically significant. HER2 status did not affect survival period according to chemotherapy group.
Conclusion:   Immunohistochemistry findings of HER2 expression in Turkish breast cancer patients were similar to those found in the published reports. A shorter survival period was observed in HER2 3+ patients, but the difference was not statistically significant.     

Wound approximation with tissue glue in circumcision

BACKGROUND: To assess the feasibility of using tissue glue in the approximation of circumcision wounds in children. PATIENTS AND METHODS: A prospective randomized trial was carried out on 30 boys (age, 1-10 years) admitted to the Kahramanamaras Sutcuimam University Medical Faculty, Turkey. The results of wound approximation in circumcision with cyanoacrylate tissue glue and suturing with interrupted 5/0 plain catgut were compared. The operations were carried out by the same surgeon using an identical technique. The wounds were assessed 1 day, 3 days, 1 week and 1 month postoperatively. RESULTS: There was no difference between the two groups in the rates of wound inflammation, infection, bleeding and dehiscence, although cosmetic appearance was better in the tissue glue group. The operation time was also shorter in this group. CONCLUSION: Using tissue glue for wound approximation in circumcision is a feasible alternative.
