BACKGROUND:This study compared the predictive accuracy of four scoring systems, namely Acute Physiology and Chronic Health Evaluation II (APACHE II), Sequential Organ Failure Assessment (SOFA), Simplified Acute Physiology Score II (SAPS II), and Mortality in Emergency Department (MEDS), for estimating prognosis in patients with necrotizing fasciitis.

Disruption of nocturnal sleep in an intensive care unit may remarkably affect production of melatonin, which is also known to have anti-inflammatory properties. In the present study, we aimed to investigate the effect of sleep quality on melatonin levels and inflammation after surgery. Thus, we compared the patients, who were screened in the side-rooms where the lights were dimmed and noise levels were reduced, with the patients who received usual care. Preoperative and postoperative urine 6-sulphatoxymelatonin, serum interleukin-1 (IL-1), interleukin-6 (IL-6), and c-reactive protein (CRP) levels were measured and data on sleep quality was collected using the Richards–Campbell Sleep Questionnaire. Postoperative CRP and IL-6 levels were greater in the control group than in the experimental group, whereas postoperative 24 h melatonin levels were greater than preoperative levels and the difference was steeper in the experimental group in concordance with sleep quality scores. Thus, the regulation of light and noise in ICUs may help the recovery after major surgeries in patients, potentially by increasing melatonin production, which has anti-inflammatory properties.

In this study, we investigated the affect and the role of growth factors on liver damage. 110 Sprague–Dawley rats were divided into 11 groups: a sham group, a control group, HGF, EGF, IGF, TGF groups of irreversible jaundiced rats and a control group and HGF, EGF, IGF, and TGF groups of reversible jaundiced rats (n = 10). In the irreversible jaundiced groups, the common bile duct was explorated, double ligated, and cut. 150 μg/kg/day HGF, 5 μg/kg/day EGF, 5 μg/kg/day IGF, and 5 μg/kg/day TGF β-1 were injected intraperitoneally after the seventh post-operative day. In the reversible jaundiced group, the common bile duct was ligated and the ligation was resolved on the seventh post-operative day. For 5 days, growth factors were injected at the same dose. Ductal proliferation scores significantly decreased after growth factor administration in the EGF-A and TGF-A groups. Furthermore, ductal proliferation was decreased in the TGF-B group. As a result of this study, HGF was effective in the irreversible jaundiced groups and ineffective in the reversible jaundice groups. EGF was effective in the reversible jaundiced groups and ineffective in the irreversible jaundiced groups. In both the irreversible jaundiced and reversible jaundiced groups, IGF was ineffective, although TGF β-1 was effective. We believe that these results arise from the positive effects of effective doses of growth factor on liver damage.

Background/aim: Hyperparathyroidism is an endocrine disorder characterized by hypercalcemia. Because of calcium's effects on parathyroid glands, bone, intestines, and kidneys, it has an important place in homeostasis. The results of studies regarding hyperparathyroidism hemostasis are conflicting. Thromboelastography helps to evaluate all steps of hemostatic system. Our aim in this study was to investigate the possible role of hemostatic mechanisms in the development of thrombosis in hyperparathyroid patients with the modified rotation thromboelastogram (ROTEM). Materials and methods: Twenty-two patients with primary hyperparathyroidism (PHPT) and 20 healthy controls were involved. This study was conducted in Eskisehir Osmangazi University Faculty of Medicine, Endocrinology and Hematology clinics for 2 years. The complete blood count, fibrinogen, D-dimer levels, prothrombin time, activated prothrombin time, and ROTEM parameters [clot formation time (CFT), clotting time (CT), and maximum clot formation (MCF)] were determined by two activated tests, INTEM and EXTEM analyses. A thromboelastographic evaluation was performed in the preoperative and postoperative (3 months after surgery) periods.Results: In INTEM assay, the CT (p = 0.012) and CFT (p = 0.07) values were increased in preoperative PHPT patients compared with the control group. Although there was a decrease in the postoperative CT and CFT values, no statistical difference was found. Conclusion:The prolongation of the CT and CFT values were consistent with a hypocoagulable state in patients with PHPT. Hyperparathyroidism causes a hypocoagulable state that can be successfully assessed by ROTEM. Hemostatic changes, do not seem to have an effect on increased cardiovascular mortality.

Sigmoid volvulus is one of the acute abdomen that requires endoscopic intervention and/or surgery. High recurrence rates after detorsion require patients to be operated under elective conditions. A 32 year oldmental retarded male patient was operated for recurrent sigmoid volvulus. In this study, we aimed to present a giant recurrent sigmoid volvulus case accompanied by diaphragmatic hernia.

Gelişen teknoloji ile birlikte rektum kanseri cerrahisinin uygulamalarında da birtakım yenilikler ortaya çıkmıştır. Konvansiyonel laparoskopinin yanı sıra, tek insizyonla laparoskopik cerrahi, robotik cerrahi ve transanal total mezorektal eksizyon bu yöntemler arasındadır. Birbirlerine ve açık cerrahiye üstünlükleri halen bir güncel araştırma konularıdır.

Objectives: Adrenal masses are more frequently detected in autopsy series in recent years and are more frequently detected in clinical practice due to the development of radiological examinations. After the detection of an adrenal mass, the first two important questions come to mind. Does the mass hormonally active (functionally) or not active (non-functional), and this mass is a benign formation or is it malignant? The answer to these two questions is the obligatory questions that clinicians must answer in order to make an operation decision. The decision of operation in non-functioning adrenal masses is directly proportional to the mass's neoplastic potential. If a preoperative histopathological diagnosis is not available; this potential is predicted by the size of the mass in radiological imaging. It is shown that the malignancy rate in adrenal masses is higher in lesions 6 cm and above. In this study, we aimed to determine whether the rate of malignancy is really high in histopathological examination as a result of adrenalectomy operations performed in our clinic between the years of 2010-2012. Methods: Fourteen women and 4 men with 6 cm or higher adrenal masses patients which performed adrenalectomy by Eskişehir Osmangazi University Faculty of Medicine Department of General Surgery between 2010-2012 were included in this study. The results of the final histopathological analysis were classified retrospectively. Results: The rate of malignancy in adrenal masses of 6 cm or more supported by the literature was found to be high in our clinical series. Conclusions: As a result of our clinical retrospective study, we think that the extent of the formation in the related gland is highly effective and significant in making an operation decision before adrenalectomy.

Pheochromocytoma is a neuro-endocrine tumor which secretes catecholamine. It is rare in pregnancy. Misdiagnosis as gestational hypertension or preeclampsia may cause delays in diagnosis. We aimed to discuss a case of pheochromocytoma during pregnancy presenting with hypertension. A 27-year-old female patient with 15-weeks of pregnancy was found to have a 45x55 millimeter mass on the left adrenal gland while she was complaining left side pain. Physical examination revealed hypertension. 24hour urine catecholamine levels were elevated. Abdominal MRI was consistent with pheochromocytoma. After appropriate preparation, laparoscopic adrenalectomy was performed for the left adrenal gland in second trimester. Catecholamine levels decreased after the operation. The pathology was consistent with pheochromocytoma. The patient delivered a baby by cesarean section at 37th gestational week. Pheochromocytoma during pregnancy is a rare but important cause of morbidity and mortality for mother and fetus. Therefore, it should be considered in the differential diagnosis especially in pregnant women presenting with hypertension in first trimester.
