Effect of Rutin on Cytarabine-Associated Pulmonary Oedema and Oxidative Stress in Rats.

Cytarabine is effectively used in the treatment of adult acute leukemia, but it has a dose-limiting side effect of fatal pulmonary oedema because it increases the vascular permeability of the alveolar capillaries. The aim of the present study was to conduct a radiological, biochemical and histopathological investigation of the effect of rutin on cytarabine-associated pulmonary oedema in rats. Rats were treated with a combination of rutin+cytarabine by administering oral rutin at a dose of 50 mg/kg; other rat groups were orally administered the same volume of physiological saline. One hour after administration of rutin or saline, the rutin+cytarabine and cytarabine groups received an intraperitoneal injection of cytarabine (200 mg/kg). This administration procedure was repeated once a day for 14 days. Radiologically, 50% of the animals given cytarabine alone showed lung oedema, but the rutin+cytarabine group showed no oedema. The inclusion of rutin decreased the amounts of cytarabine-associated malondialdehyde, tumour necrosis factor-α, and nuclear factor-κB in the lung tissue. Rutin also inhibited the reduction of total glutathione by nitric oxide. These findings suggest that rutin may be a beneficial adjunct that can minimise the development of cytarabine-associated pulmonary oedema.

Contribution of DECT in detecting serosal invasion of gastric cancer

Background/aim: This study aimed to investigate the relationship between the iodine concentration (IC) of perigastric fat tissue as assessed by dual-energy computed tomography (DECT) and serosal invasion of gastric cancer. Materials and methods: A total of 41 patients underwent preoperative staging evaluation for gastric cancer using DECT between July 2015 and March 2018. Patients were divided into 2 groups based on pathology results: serosal invasion (stage T4a) and intact serosa (stages T1­T3). Cutoff values, the diagnostic efficacy of IC in the perigastric fat tissue, and the perigastric fat tissue/tumor (P/T) ratio were determined. Results: Among the 41 patients, 22 had stage T4a gastric cancer and 19 patients had gastric cancer with a stage lower than T4a. The mean IC of perigastric fat tissue and the P/T ratio were significantly higher in patients with serosal invasion than in those with intact serosa (P < 0.001). During the arterial phase, the area under the curve (AUC) was 0.915 and 0.854 for the IC of perigastric fat tissue and the P/T ratio, respectively. During the venous phase, the AUC was 0.890 and 0.876 for the IC of perigastric fat tissue and the P/T ratio, respectively. Conclusion: The IC in the perigastric fat tissue seems to be a reliable indicator for serosal invasion of gastric cancer.

Diagnostic evaluation and treatment of patients with rectus abdominis hematoma.

PURPOSE: To identify clinical characteristics, treatment modalities, and course of spontaneous rectus sheath hematoma (SRSH). In the literature, there is no prospective clinical trial that is intended for treatment in clinical research. METHODS: Seventeen SRSH patients diagnosed and treated between March 2012 and March 2014 at the general Surgery Department of Erzincan University Training and Research Hospital were included. Age, sex, weight, height, predisposing factors, comorbid diseases, Charlson index, current medical treatment, physical examination signs, imaging methods, lowest hemoglobin value, blood type, SRSH type, INR/Factor V Leiden mutation/Factor VII/Factor VIII/Factor X/Protein S/Protein C values, treatment method, transfusions hospitalization duration, and outcome were studied. RESULTS: Thirteen patients were female. The mean age was 63.3 ± 18.7 years (range, 22-87 years), and the mean BMI was 27.8 ± 3.5 (range, 20.9-33.7). Six patients had Grade I SRSH, 5 had Grade II SRSH, and 6 had Grade III SRSH. Thirteen were hospitalized for a mean duration of 9.3 ± 8.1 days (range, 1-30 days). The death rate attributable to SRSH was 5.8%. CONCLUSION: Early diagnosis of SRSH by ultrasonography and/or computerized tomography is important for a low mortality rate. Even though medical treatments are important, arterial embolization by interventional radiology, or more radical interventions such as surgery, may be required.

MRI of Residual Red Bone Marrow in the Distal Femur of Healthy Subjects.

BACKROUND: The purpose of our study is to examine the correlation of the residual red bone marrow areas of distal femoral metaphysis with the age, gender, weight and hemoglobin (hgb) values; evaluate the results, and comprehend the importance of these residual areas in the light of the results. MATERIAL/METHODS: 140 nonsmoking patients between the ages of 26 and 72 (92 women, 48 men) who had knee MR examinations were included in the study. The residual red bone marrow areas in the distal femoral metaphysis in MR images were examined by a radiologist. The areas were separated into grades according to their sizes. The hemoglobin values of the cases were measured. The size of the residual red bone marrow area and the age, gender, weight and hemoglobin values of the cases were compared by using the Tukey and Chi-Square Tests. RESULTS: Although no significant differences were observed between the mean ages, weights and hemoglobin values of the grades, a significant difference was detected between the gender distribution The male group had less residual red bone marrow in the distal femoral metaphysis than the female group (p=0.003). CONCLUSIONS: We observed that the hypointensities due to residual red bone marrow observed in the T1WS of the distal femoral metaphysis are not related with the age, weight and hemoglobin values. No grade 2 and grade 3 patient was detected in male group. We observed that these hypointense areas showed difference according to the gender variable; however, were not affected by the hemoglobin values over certain levels.

Assessment of the relationship between aortic pulse wave velocity and aortic arch calcification.

OBJECTIVES: We aimed to assess arterial stiffness parameters and to investigate the relationship between these parameters and aortic calcification in patients with aortic arch calcification and without symptomatic atherosclerotic disease. STUDY DESIGN: The population of this study consisted of 41 patients with aortic arch calcification verified by chest X-ray (group I, 17 males, mean age 70±5 years) and individuals without aortic arch calcification (group II, 17 males, mean age 68±6 years). Subjects with symptomatic or known vascular disease were excluded from the study. The arterial stiffness parameters of all subjects were measured non-invasively with a SphygmoCor device. Aortic pulse wave velocity (PWV), augmentation pressure (AP), augmentation index (AIx) and heart rate normalized augmentation index (AIx@75) were used as parameters of arterial stiffness. RESULTS: The two groups were compared according to demographic characteristics, medications currently being taken, and levels of serum lipids. There was no significant difference between the groups. AP in group I was significantly higher than that of group II (p=0.002). AIx and AIx@75 were similar in both groups. Aortic PWV of group I was significantly higher than that of group II (p<0.0001). CONCLUSION: According to the results of this study, the presence of aortic calcification, verified by chest radiography, was associated with increased aortic PWV.

Correlation of Bowel Wall Thickening Seen Using Computerized Tomography With Colonoscopies: A Preliminary Study.

PURPOSE: Bowel wall thickening (BWT) is a common finding in abdominal computerized tomography imaging (CTi). The purpose of the present study was a prospective assessment and management of patients who have BWT in abdominal CTi. MATERIALS AND METHODS: This study was conducted between January 2012 and July 2014 at Erzincan University Hospital, Turkey, with 64 patients who were admitted to the emergency and general surgery department. All of the patients had received colonoscopies due to BWT seen in abdominal CTi. RESULTS: Twenty-three (36%) female and 41 (64%) male patients were included in the study. The mean age was 56.2 years (range, 14 to 84 y). The positive predictive value of CTi for BWT was 87.5%. The positive predictive value of a CTi diagnosis of the disease according to a radiologist's report was 78.1%. Common pathologies detected by colonoscopy included neoplasia and inflammatory bowel disease. CONCLUSIONS: Diagnosis of BWT by abdominal CTi reveals pathologies in many cases. Colonoscopies will be helpful in the differential diagnosis.

A Rare Case of Isolated Cystic Hydatid of Thyroid Gland.

Hydatid cysts are most frequently localized within the liver and lungs, although they can also be found in highly vascularized tissues such as the brain, muscle, heart, pancreas, adrenal, and thyroid glands.A 65-year-old female patient was admitted to our clinic with complaints of a progressively growing mass that was compressing the surrounding tissues and causing respiratory distress. The pathological result was obtained as cytic hydatid.In patients with diagnosed hydatid cysts in the liver, systemic evaluation is necessary to rule out involvement of other organs. Among patients presenting with growths located in the neck, primary hydatid cyst of the thyroid gland must be considered in endemic regions.

Gossypiboma Mimicking a Mesenchymal Tumor: A Report of a Rare Case.

BACKGROUND: Gossypiboma is the term for a surgical complication resulting from foreign materials such as a surgical sponge or gauze that was accidentally left inside a patient's body. CASE REPORT: Here, we report the case of a 62-year-old woman with gossypiboma. She underwent surgery due to an abdominal mass that was preoperatively considered a tumor. Intra-postoperatively, it was diagnosed as gossypiboma. CONCLUSIONS: For the prevention of gossypiboma during the pre-operative and post-operative periods, counting sponges and surgical equipment must be done very carefully. If there is any doubt postoperatively, direct abdominal imaging may be helpful.

Giant Cutaneous Leiomyosarcoma Originating From the Abdominal Wall: A Case Report.

BACKGROUND: Leiomyosarcoma, a rare type of tumor, accounts for 5-10% of all soft tissue tumors. CASE REPORT: A 44-year-old male patient was admitted to the emergency service of our medical faculty with the complaints of fatigue and abdominal mass. CONCLUSIONS: The pathology result was leiomyosarcoma. Leiomyosarcoma of the skin is rare and our case is the largest such lesion reported in the literature.

Urethrogluteal fistula developing secondary to the use of clean intermittent self-catheterization: first case report in the literature.

Clean intermittent self-catheterization is the standard method for bladder evacuation in these patients today. The patient was diagnosed with urethrogluteal fistula and gluteal-perineal abscess by radiological evaluation. Gluteal drainage decreased after cystostomy. In our paper, a case of urethrogluteal fistula and pelvic urinoma that developed as a result of the use of clean intermittent self-catheterization (CISC), which is rarely found in the literature, is presented.

A case report of esophageal perforation: Complication of nasogastric tube placement.

PATIENT: Male, 70 FINAL DIAGNOSIS: Esophageal perforation Symptoms: Abdominal pain • nausea • vomiting MEDICATION: - Clinical Procedure: - Specialty: Surgery. OBJECTIVE: Unusual clinical course. BACKGROUND: Esophageal perforation is a well-defined and severe clinical condition. There are several etiologies of esophagus perforation. CASE REPORT: We report the case of a 70-year-old Caucasian man who underwent an emergency cholecystectomy due to acute cholecystitis. Two days after surgery, his condition deteriorated. Thorax computerized tomography revealed an esophageal perforation. CONCLUSIONS: Esophageal perforation due to nasogastric application is relatively rare but the consequences are potentially serious. The anatomy of the upper gastrointestinal system should be understood by all healthcare professionals involved in the treatment.

How could such a wide piece of tree root pass through the narrow pyloric orifice? An extremely rare case.

PATIENT: Female, 30 FINAL DIAGNOSIS: Phytobezoar Symptoms: Nausea • vomiting MEDICATION: - Clinical Procedure: - Specialty: - OBJECTIVE: Rare disease. BACKGROUND: Phytobezoars are a common type of bezoar known to accumulate in the gastrointestinal system. CASE REPORT: A 30-year-old mentally retarded woman was operated on due to small bowel obstruction. A piece of tree root was extracted from the ileum. The patient was discharged from the hospital on postoperative day 7. CONCLUSIONS: Due to difficulties in determining the nature of the bezoar preoperatively, small bowel obstruction due to a phytobezoar is not a common diagnosis. For bezoars, prevention is considered preferable to treatment.

Diagnostic value of color Doppler ultrasonography and MDCT angiography in complications of hemodialysis fistulas and grafts.

PURPOSE: The purpose of the study was to compare the diagnostic value of color Doppler ultrasonography (CDUS) and multidetector computed tomography (MDCT) angiography against that of digital subtraction angiography (DSA) or surgery in the evaluation of failing hemodialysis arteriovenous fistulas (AVFs). MATERIALS AND METHODS: CDUS and MDCT angiography were performed with 41 patients (24 men, 17 women; mean age 55.8) with dysfunctional hemodialysis fistulas. The presence of stenosis, thrombosis, aneurysm, pseudoaneurysm and seroma were recorded. The sensitivity, specificity, positive and negative predictive values (PPV and NPV) and accuracy of CDUS and MDCT angiography were calculated both individually and in combination for the detection of vascular segments with significant stenosis, thrombosis, aneurysms, pseudoaneurysms, perivascular complications and stenosis subgroups. RESULTS: Sixty-four segmental lesions were diagnosed by DSA or surgery. Sensitivity, specificity, PPV, NPV and accuracy of CDUS for all vascular tree lesions were 85.9%, 99.2%, 96.4%, 96.7% and 94.5%, respectively. For MDCT angiography the figures were 96.8%, 99.6%, 98.4%, 99.2% and 98.5%, respectively. When both tests were used in combination, sensitivity, specificity, PPV, NPV and accuracy for all vascular tree lesions rose to 100%. CONCLUSION: Combined use of MDCT and CDUS for diagnosis of AVF dysfunctions is of equivalent value to surgery or DSA, a gold standard technique.

Evaluación diagnóstica y tratamiento de pacientes con hematoma de la vaina de los rectos / Diagnostic evaluation and treatment of patients with rectus abdominis hematoma

OBJETIVO: Identificar las características clínicas, las modalidades de tratamiento y la evolución del hematoma espontáneo de la vaina del recto (HEVR). En la literatura, no hay ningún estudio clínico prospectivo sobre el tratamiento en un ámbito de investigación clínica. MÉTODOS: Se incluyeron en el estudio 17 pacientes con HEVR que fueron diagnosticados y tratados entre marzo de 2012 y marzo de 2014 en el Departamento de Cirugía General del Hospital Docente e Investigador de la Universidad de Erzincan. Se evaluaron los datos de edad, sexo, peso, altura, factores predisponentes, comorbilidades, índice de Charlson, tratamiento médico actual, signos a la exploración física, exploraciones de diagnóstico por la imagen, valor mínimo de la hemoglobina, tipo sanguíneo, tipo de HEVR, valores de INR/mutación de factor V Leiden/factor VII/factor VIII/factor X/proteína S/proteína C, método de tratamiento, transfusiones, duración de la hospitalización y evolución clínica. RESULTADOS: Trece pacientes fueron mujeres. La media de edad fue de 63,3 ± 18,7 años (rango, 22-87 años), y la media del IMC fue de 27,8 ± 3,5 (rango, 20,9-33,7). Seis pacientes presentaban un HEVR de grado I, 5 un HEVR de grado II y 6 un HEVR de grado III. Trece fueron ingresados durante un periodo medio de hospitalización de 9,3 ± 8,1 días (rango, 1-30 días). La tasa de mortalidad atribuible al HEVR fue del 5,8%. CONCLUSIONES: Un diagnóstico precoz del HEVR mediante ecografía y/o tomografía computarizada es importante para obtener una tasa de mortalidad baja. A pesar de que los tratamientos médicos son importantes, pueden ser necesarias una embolización arterial mediante radiología intervencionista o intervenciones más radicales como la cirugía
