Abstract
PURPOSE To investigate the acute effects of pseudoephedrine (PE) on choroidal thickness in healthy young patients. METHODS Fifty patients with nasal and sinus congestion who were prescribed 60 mg oral PE at the otolaryngology department were recruited for this study. The enhanced depth imaging (EDI) optic coherence tomography (OCT) (Spectralis OCT; Heidelberg Engineering, Heidelberg, Germany) choroidal thickness measurements were performed at baseline and 1, 3 and 6 hours at 7 points. RESULTS The right eyes of 50 healthy subjects (22 women and 28 men) were included in this study. The mean choroidal thickness at fovea was 293.12 μm, 279.80 μm, 295.80 μm, and 294.52 μm at baseline, 1, 3 and 6 hours respectively. A significant reduction in choroidal thickness versus baseline was observed at all points at 1 hour. CONCLUSIONS The choroidal thickness decreased 1 hour after oral administration of PE and returned to baseline thickness at 3 hours. We suppose that this transient decrease might be associated with vasoconstriction due to activation of sympathetic alpha adrenoceptors.

Abstract
OBJECTIVES Psoriasis vulgaris is one of the most common skin disorders. Patients with psoriasis carry an excessive risk of coronary artery disease. Visceral adipose tissue around the heart affects the heart and coronaries by secreting proatherogenic mediators. It can be evaluated easily by measurement of epicardial fat thickness (EFT). The aim of this study was to investigate EFT in patients with psoriasis vulgaris. STUDY DESIGN One hundred and fifteen adult patients (62 male; mean age 33.6±6.0 years) with psoriasis vulgaris (Group 1) and 60 age- and sex-matched healthy individuals (28 male; mean age, 32.5±8.3 years) (Group 2) were included in this study. EFT was obtained by transthoracic echocardiography. Disease-specific characteristics of the patients were recorded. Serum glucose, lipid profile and high-sensitive C-reactive protein (hs-CRP) levels were measured. RESULTS EFT and hs-CRP were significantly higher in Group 1 than in Group 2 (5.7±1.2 vs. 4.1±1.0 mm, p<0.001 and 0.52±0.45 mg/dl vs. 0.19±0.17 mg/dl, p<0.001, respectively). The psoriasis disease activity score and hs-CRP were found to be independent predictors of EFT in patients with psoriasis vulgaris (ß=0.21, t=2.67, p=0.01 and ß=0.62, t=7.72, p=0.001, respectively). CONCLUSION Our findings indicate that EFT was significantly higher in patients with psoriasis vulgaris compared with the controls. It was more prominent in patients with severe disease.

Abstract
OBJECTIVES Previous studies have demonstrated the role of inflammation in acute heart failure. The neutrophil-to-lymphocyte ratio was found to be a useful inflammatory marker for predicting adverse outcomes. We hypothesized that an elevated neutrophil-to-lymphocyte ratio would be associated with increased mortality in acute heart failure patients. METHODS The study cohort consisted of 167 acute heart failure patients with an ejection fraction <50%. The primary endpoint was in-hospital mortality, and the patients were divided into two groups according to in-hospital mortality. RESULTS In a multivariate regression analysis, including baseline demographic, clinical, and biochemical covariates, the neutrophil to lymphocyte ratio remained an independent predictor of mortality (OR 1.156, 95% CI 1.001 - 1.334, p = 0.048). CONCLUSION In conclusion, an elevated neutrophil-to-lymphocyte ratio seems to be a predictor of short-term mortality in patients with acute heart failure and a reduced left ventricular ejection fraction.

Abstract
A number of chemotherapeutic agents and treatment strategies have been developed or designed to treat cancer patients. However, chemotherapeutic regimens frequently cause side-effects, one of which is anemia, a severe clinical problem for cancer patients. Erythropoietin is commonly used to treat anemia and reduce blood transfusions in cancer patients. Another agent which has potential use in cancer therapy is heparin, a glycosaminoglycan with a negative charge, known to increase the clearance of tumor cells from the blood in mice and also has anti-metastatic effects. In this current study, we investigated the effects of rEpo and heparin either as single agents or in combination on B16F10 melanoma cells. Contrary to our expectations based on the previous in vitro and in vivo studies, we have not found a significant growth-promoting effect of rEpo on B16F10 cells. We have also not observed a significant cytotoxic effect of heparin on B16F10 melanoma cell as assayed by MTT test (p > 0.05). However, heparin did significantly prevent the migration/proliferation of B16F10 cell in the wound assay as compared to the control cells after 24 h of incubation (p < 0.001). In addition, this effect of heparin was not prevented when rEpo was present in the medium in the wound assay (p < 0.01 as compared to the control). These results suggest that heparin may have a therapeutic potential as an anti-metastatic drug for cancer.

Abstract
OBJECTIVE Cardiac involvement has been increasingly recognized in patients with polycystic ovary syndrome (PCOS). Identification of the earliest asymptomatic impairment of left ventricular (LV) performance may be important in preventing progression to overt heart failure. Our aim was to investigate LV function with different echocardiographic techniques in patients with PCOS. METHODS Thirty patients with PCOS and 30 age and body mass index matched healthy subjects were enrolled to this cross-sectional observational study. All subjects underwent echocardiography for assessment of resting LV function as well as two-dimensional speckle tracking echocardiography (2D-STE) and real-time three-dimensional echocardiography (3D-Echo). Global longitudinal strain (GLS) was calculated from 3 standard apical views using 2D-STE. Student t-test, chi-square test, Pearson's, and Spearman's correlation analysis were used for statistical analysis. RESULTS The early mitral inflow deceleration time (DT), isovolumetric relaxation time (IVRT) and E/Em ratio were increased in the PCOS group (p<0.05 for all). Waist-to-hip ratio, fasting insulin, homeostasis model assessment of insulin resistance (HOMA-IR) and low-density lipoprotein (LDL) levels were higher in PCOS group (p<0.05 for all). Significant correlation was observed between DT, IVRT and insulin value, HOMA-IR (p<0.05 for all). On 3D-Echo evaluation, none of the patients in both groups had LV systolic dysfunction with comparable LV ejection fraction and LV volumes. 2D-STE showed that GLS was significantly reduced in the PCOS group compared to control group (-16.78 ± 0.56% vs. -18.36 ± 1.04%, p<0.001). The GLS was found to be negatively correlated with waist-to-hip ratio and LDL values (p<0.05 for all). CONCLUSION These results indicate that PCOS may be related to impaired LV systolic function detected by 2D-STE. In addition, PCOS may lead to diastolic dysfunction. Reduced GLS might be an early indicator of cardiac involvement in this patient population.

Abstract
OBJECTIVE The neutrophil -to- lymphocyte ratio (NLR) is a new predictor for cardiovascular risk and mortality. The SYNTAX score is an angiographic tool used in grading the complexity of coronary artery disease (CAD). However, its relation with CAD severity and complexity is not yet known. We hypothesized that NLR would be associated with a greater complexity of CAD as assessed using the SYNTAX score. METHODS This cross-sectional observational study included 106 patients who had undergone coronary angiography for stable angina pectoris and 69 patients who had normal coronary angiogram. Baseline NLR was measured by dividing neutrophil count to lymphocyte count. The patients were classified two groups as CAD (-) (n=69) and CAD (+) (n=106), then patients in CAD (+) group were divided into 3 groups according to SYNTAX scores (SYNTAX score 1-22, 23-32, >32) as pointed in European Society of Cardiology (ESC) revascularization guideline. Statistical analysis was performed using the Mann-Whitney U and Kruskal-Wallis tests, and multiple logistic regression analysis was used to identify the independent predictors of complexity of CAD-SYNTAX score. RESULTS Patients with CAD had a significantly higher value of NLR [1.6 median (1.2-3.3 IQR) vs. 2.3 median (1.8-3.0 IQR) p<0.001]. The group with high SYNTAX scores (>32) more frequently had diabetes mellitus (DM), hypercholesterolemia (HL), were of older age, and also had significantly elevated NLR values [2.4 (1.3-2.6), 2.6 (2.3-3.9), 2.0 (1.5-2.6) p=0.006]. In univariate analysis, age, DM, HL, creatinine, neutrophil count and NLR were predictors of high SYNTAX score. In the multiple logistic regression analysis, only NLR [odds ratio (OR)=2.1, 95% confidence interval (CI) 1.2-3.8, p=0.09], was identified as independent predictor of a high SYNTAX score. CONCLUSION NLR is a strong clinical laboratory value that is associated with presence and complexity of CAD.

Abstract
OBJECTIVES The neutrophil to lymphocyte ratio (NLR) has been investigated as a new predictor for cardiovascular risk. Admission NLR would be predictive of adverse outcomes after primary angioplasty for ST-segment elevation myocardial infarction (STEMI). METHODS A total of 2410 patients with STEMI undergoing primary angioplasty were retrospectively enrolled. The study population was divided into tertiles based on the NLR values. A high NLR (n = 803) was defined as a value in the third tertile (>6.97), and a low NLR (n = 1607) was defined as a value in the lower 2 tertiles (≤6.97). RESULTS High NLR group had higher incidence of inhospital and long-term cardiovascular mortality (5% vs 1.4%, P < .001; 7% vs 4.8%, P = .02, respectively). High NLR (>6.97) was found as an independent predictor of inhospital cardiovascular mortality (odds ratio: 2.8, 95% confidence interval: 1.37-5.74, P = .005). CONCLUSIONS High NLR level is associated with increased inhospital and long-term cardiovascular mortality in patients with STEMI undergoing primary angioplasty.

Abstract
BACKGROUND Neutrophil/lymphocyte ratio (NLR) has been associated with poor outcomes in patients with cardiovascular diseases. However, little is known about the role of NLR in patients with thromboembolic stroke due to atrial fibrillation (AF). We aimed to compare the NLR ratios between non-valvular AF patients with or without thromboembolic stroke. METHODS A total of 126 non-valvular AF patients with or without stroke were included in the study; 126 consecutive patients (52 males and 74 females), mean age, 70 ± 10.2 years old. No patient had a recent history of an acute infection or an inflammatory disease. Baseline NLR was measured by dividing neutrophil count to lymphocyte count. WBC count>12.000 cells per μL or <4.000 cells per μL and high body temperature>38 º are excluded from the study. RESULTS Mean NLR was significantly higher among persons with stroke compared to individuals without a stroke (5.6 ± 3.4 vs. 3.1 ± 2.1, p=0.001). There were no significant differences in RDW levels between the two groups (p>0.05). HAS-BLED and CHADS(2) scores were significantly higher in the stroke group. CONCLUSION Higher NLR, an emerging marker of inflammation, is associated with thromboembolic stroke in non-valvular AF patients.

Abstract
Shone's syndrome is a very rare cardiac malformation composed of four obstructive congenital lesions, which include the parachute mitral valve (PMV), supravalvular ring, subaortic stenosis, and coarctation of aorta. Diagnosis requires a comprehensive examination including a carefully performed echocardiography. It is extremely unusual for a patient to remain undiagnosed during adulthood. Here we report a 26-year-old male patient with Shone's syndrome and patent ductus arteriosus (PDA). The patient reported that he had been suffering from exercise intolerance and aggravating dyspnea. Two years ago, he was operated on in another hospital based on the wrong diagnosis of mitral valve prolapse and subaortic membrane. Transthoracic echocardiography revealed the existence of a PMV, which led to severe mitral stenosis through a previously implanted mitral annular ring. Other components of Shone's syndrome, subaortic membrane and aortic coarctation, together with PDA, were also observed. Another operation was suggested, but the patient refused. During the two year follow-up period, in spite of an atrial fibrillation attack and deteriorating dyspnea, the patient still did not want another operation. Once any of the four components of the Shone's complex is detected, clinicians must look for the presence of other lesions.

Abstract
Nowadays, herbal combinations are commonly used in Turkey and around the world. In particular, an herbal combination including Tribulus terrestris (TT), Avena sativa (AS), and Panax Ginseng (PG), which may be effective in treatment of atherosclerosis and thrombosis, is used by patients with coronary artery disease. In this paper, we will report three cases with coronary stents who were diagnosed with acute coronary syndrome while using this herbal combination of TT, AS and PG together with anti-aggregant medications. A 45-year-old man presented with chest pain and coronary angiography confirmed a total occluded stent in left anterior descending artery which was implanted a year ago. Balloon dialation was performed to dilate the stent, resulting in full opening of the vessel. The second case, a 53-year-old woman, was admitted to the hospital with chest pain. Coronary angiography confirmed a total occluded stent, which had been implanted three months ago. A balloon was performed to dilate the stent and it was fully opened. The third case, a 62-year-old man, presented with chest pain. Coronary angiography was performed and there was a 98% stenosis of the circumflex stent, which was implanted three months ago. A balloon was performed to dilate the stent and it was fully opened. It was learnt that all three patients had used the same herbal combination (TT, AS and PG) with dual anti-aggregant therapy for three months ago to presentation in the clinic. Patients were discharged with the suggestion not to use this herbal combination with dual anti-aggregant therapy. There were no problems during the four month follow-up period. Stent thrombosis may be caused by interactions between herbal combination (TT, AS and PG) and clopidogrel in these patients under dual antiaggregant therapy.

Abstract
OBJECTIVE The aim of this study was to evaluate the effects of hemodialysis (HD) on right ventricular echocardiographic parameters in patients with end-stage renal failure (ESRF). METHODS Forty-three uremic patients who underwent echocardiography before and 30 minutes after dialysis included in this prospective observational study. Right ventricular systolic function was evaluated using tricuspid annular plane systolic excursion (TAPSE) by M-mode echocardiography and tricuspid lateral annular systolic velocity (Sa) by tissue Doppler echocardiography whereas diastolic function was evaluated using tricuspid early (E) and late (A) diastolic flow velocities by conventional and tricuspid lateral annular early (Ea) and late (Aa) diastolic velocities by tissue Doppler echocardiography. Myocardial performance index was taken as an indicator of global functions. Paired t test or Wilcoxon test were used for statistical analysis where appropriate. RESULTS E decreased significantly (68 ± 13 cm/s and 56 ± 12 cm/s before and after HD, respectively; p<0.0001) but A did not (p=0.797).TAPSE was 1.84 ± 0.34 cm before HD and showed a significant increase to 2.03 ± 0.20 cm after HD (p=0.006). Right ventricular MPI, Sa and Aa did not change significantly by dialysis (p=0.504; p=0.118 and p=0.150 respectively) whereas Ea decreased to 8.8 ± 2.5 cm/s from 11.3 ± 3.4 cm/s (p<0.001). Ea/Aa ratio also decreased significantly to 0.69 ± 0.35 from 0.84 ± 0.44 with HD (p=0.007). CONCLUSION The results of this study indicates that parameters of right ventricular systolic function such as Sa and MPI are independent of preload whereas the conventional and tissue Doppler parameters of right ventricular diastolic function are preload dependent in patients with end-stage renal failure who undergo regular hemodialysis.

Abstract
We present a 19-year-old asymptomatic female patient in whom isolated pulmonary supravalvular stenosis and pulmonary artery aneurysm were incidentally detected. On cardiologic examination, a systolic murmur was heard over the lungs, right axis deviation was seen on the electrocardiogram, and marked appearance of the pulmonary artery was noted on the chest X-ray. On transthoracic echocardiography, the pulmonary artery trunk was found to be wider than normal, and there were mild pulmonary and tricuspid regurgitation. Color Doppler examination showed a turbulent flow 2 cm distal to the pulmonary valve. Transesophageal echocardiography showed a supravalvular membranous structure and a proximal pulmonary artery aneurysm. The pulmonary artery trunk was measured as 40 mm at the widest part. Thoracic computed tomography revealed that the proximal pulmonary artery aneurysm was localized to the pulmonary artery trunk and measured 41 mm. As the patient was asymptomatic and there were no signs of aneurysmatic compression or a left-to-right shunt, and due to the presence of a relatively low gradient (16 mmHg) across the stenotic area, she was scheduled to regular radiologic control.

Abstract
OBJECTIVES We evaluated the effects of endothelial dysfunction and inflammation on slow coronary flow (SCF). STUDY DESIGN The study included 26 patients (group 1; 13 females, 13 males; mean age 58.8 years) who had normal coronary arteries but SCF in three coronary vessels and 25 subjects (group 2, 14 females, 11 males; mean age 62.7 years) with normal coronary arteries and normal flow. Coronary flow was quantified according to the TIMI (Thrombolysis In Myocardial Infarction) frame count method for the left anterior descending (LAD), circumflex (Cx), and right coronary (RCA) arteries. Endothelial function was assessed by plasma asymmetric dimethylarginine (ADMA) levels, brachial artery endothelium-dependent flow-mediated dilatation (FMD), and nitroglycerin-mediated dilatation (NMD). Inflammation was assessed by high-sensitivity C-reactive protein (hs-CRP) levels. RESULTS TIMI frame count was significantly higher in group 1 compared to group 2 for each artery (p<0.001). In group 1, the mean FMD was significantly lower (6.6±1.6% vs. 11.2±1.6%, p<0.001) and the mean ADMA level was significantly higher (0.8±0.2 µmol/l vs. 0.5±0.1 µmol/l, p=0.002), whereas NMD and hs-CRP levels did not differ significantly between the two groups (p>0.05). There was a significant correlation between plasma ADMA level and TIMI frame count (RCA: r=0.50, p=0.001; cLAD: r=0.46, p=0.004; Cx: r=0.32, p=0.04) and a significant negative correlation between FMD and TIMI frame count (cLAD: r=-0.68, p=0.0003; Cx: r=-0.54, p=0.0004; RCA: r=-0.46, p=0.004), but hs-CRP level was not correlated with TIMI frame count. In multivariate analysis, only ADMA (p=0.009) and FMD (p=0.02) were significant parameters to predict SCF. CONCLUSION Our results suggest that endothelial dysfunction as determined by increased ADMA level and impaired FMD, rather than inflammation, plays a role in the etiopathogenesis of SCF.

Abstract
Chalcalburnus tarichi is an endemic cyprinid species living in the Lake Van basin, in eastern Anatolia, Turkey. The present study was undertaken to determine which hormones induce oocyte maturation in C. tarichi. The levels of 17alpha,20beta,21-trihydroxyprogesterone (20beta-S), progesterone (P), 17alpha-hydroxyprogesterone (17alpha-HOP), 11-deoxycortisol (11-DOC), and 17alpha-hydroxy-20beta-dihydroprogesterone (17,20beta-P) were measured in fish caught from Lake Van and the Karasu River, and injected with human chorionic hormone (hCG) (1,000 and 1,500 IU/kg). Oocytes of fish caught from the lake were also incubated in vitro with different doses (50, 200, and 1,000 ng/ml) of 20beta-S, 17alpha-HOP, 11-DOC, and 17,20beta-P. 11-DOC was found to be the most effective hormone among those measured for inducing oocyte maturation in vivo and in vitro. 17,20beta-P could not be determined in the plasma of any fish in vivo (P < 0.05). 1,000 IU/kg dose of hCG given by injection caused a statistically significant increase in all plasma hormone levels (P < 0.05). It was found that there was a significant decrease in the P level only at 1,500 IU/kg dose of hCG injected (P < 0.05), while the level of other hormones increased at this dose (P < 0.05). It was also determined that all the hormones were effective in germinal vesicle breakdown (GVBD) in in vitro oocyte culture (P < 0.05). However, 11-DOC was found to be the most effective hormone in GVBD at a dose of 200 ng/ml (70% GVBD). In conclusion, 11-DOC synthesized during final oocyte maturation in C. tarichi was found to be a potent inducer of GVBD, which shows that 11-DOC may be described as an oocyte maturation steroid in this species.

Abstract
In this study, the effect of leukemia inhibitory factor (LIF) on cisplatin (CDDP)-induced neuropathy was evaluated. Mice were treated with CDDP, 2 mg/kg i.p. twice a week nine times. During the last week some of the mice were also injected with LIF, 2 mug/kg s.c. every other day for a total of four injections. Development of neuropathy was evaluated with changes in tail flick latency and sensory nerve conduction velocity (NCV). At the end of the treatment period dorsal root ganglia (DRG) were microscopically examined. Some of the DRGs were explanted into extracellular matrix, covered with culture medium and incubated for 3 days. During and at the end of the incubation, cellular migration and axonal outgrowth from the DRGs were quantified. LIF proved effective in reversing the increase in tail flick latency (p<0.05) and improving the reduction in NCV induced by CDDP. CDDP led to smaller nuclear and somatic size in neurons, while with LIF, the latter was restored to control values (p<0.01). No apoptotic nucleus was observed among DRG neurons while very few and moderate numbers detected among satellite and Schwann cells, respectively. With LIF, none of the cells had apoptosis. CDDP caused a decrease in the number of migrating cells and in the length of outgrowing axons while LIF treatment restored both capacities (p<0.05) In conclusion, in CDDP-induced neuropathy, LIF was found to be effective in correcting some functional and morphological deteriorations related with major involvement of Schwann cells.

Abstract
The objective of this study was to determine treatment strategies for children admitted with pleural empyema. We reviewed the medical records of 93 consecutive patients with pleural empyema who presented in the last three years. Mean age was 3.8 years (range 3.5 months to 14 years) and the male to female ratio was 52 : 41. The left side was involved in 51 (54.8 %) cases and there was only one case with bilateral effusion. After the chest X-ray and analysis of pus obtained by thoracocentesis, the initial treatment modality was chest tube drainage in 81 (87 %) patients. Children required chest tube drainage for an average of 11.9 +/- 4.8 days. Out of the 81 children, 6 needed thoracotomy due to organized pleural fluid and another 4, who developed loculated pleural effusions, were treated with intrapleural urokinase (UK) administration. Twelve children, who had a delayed presentation with organized loculated pleural fluid and pleural thickening, underwent decortication and one, who was found to have a foreign body, found during surgery, needed an upper lobe resection. Medical management with adequate chest tube drainage and appropriate antibiotics has resulted in full resolution in the majority of patients with empyema. In cases of loculated pleural effusions identified at the early stages of the chest tube drainage, intrapleural UK administration was found to be a safe and efficient treatment modality. Thoracotomy should be reserved for late and organized empyema cases.

Abstract
There has been an increase in the number of patients admitted to our hospital with caustic esophageal injuries during the last five years. The aim of this study was to analyze the complications and results of the treatment of corrosive esophagogastric injury. Between 1990 and 2000, 120 caustic ingestion accidents were admitted to our unit. The mean age was 4 years, with a 2 : 1 male to female ratio. The average time between the caustic ingestion and admission to hospital was 14.9 days. The ingested substances were alkali in 80.9 % and acid in 19.1 % of the cases. Stenosis of the esophagus developed in 31 (25.8 %) and gastric outlet obstruction (GOO) in 6 (5 %) patients. Management of the esophageal stricture consisted of dilatation in 28 patients. Three children underwent colonic interposition without a dilatation attempt. Six children were lost to follow-up; 4 patients were successfully treated; 13 patients were still in the dilatation program at the time of writing with 6 improving and 2 patients waiting for interposition surgery; 4 patients underwent colonic interposition and 1 patient underwent resection of the stenotic part of the esophagus. Among the patients in the dilation program, we observed 4 esophageal perforations. Three of them were treated medically and further dilatations were carried out, while one was managed by colonic interposition. The treatment modalities for GOO cases consisted of pyloroplasty in 3, Billroth I in 2 and balloon dilation of the pylorus in 1 child. Although balloon dilatation of the esophagus carries the risk of perforation, it should be the first line of treatment in suitable cases. GOO cases may require surgical therapy following a detailed endoscopic evaluation.

Abstract
The combination of a thoracic cystic mass with vertebral anomalies on prenatal ultrasound suggests a neurenteric cyst. The outcome of such cysts mostly depends on the extent of the displacement and functional impairment of the adjacent organs and of the associated central nervous system defects. We present a case of a neurenteric cyst diagnosed on prenatal ultrasound at 34 weeks of gestation which was treated successfully in the early neonatal period.

Abstract
Orbital involvement is a rare manifestation of multiple myeloma. Therefore, the correct diagnosis and appropriate management are usually difficult and generally require biopsy. We report a 60-year-old woman having multiple myeloma with orbital involvement. Right orbitozygomatic craniotomy was carried out and the mass lesion was removed. After the histological examination, the diagnosis of multiple myeloma was confirmed. The clinical course and the treatment modalities of this entity are discussed in view of the literature.

Abstract
A case of lateral intrathoracic meningocele associated with a spinal intradural arachnoid cyst is reported and the cases from the literature are reviewed. Both of these lesions were detected by magnetic resonance imaging and treated surgically. Intrathoracic meningoceles are often asymptomatic and diagnosed incidentally during the evaluation of an unrelated pathology. A patient with a spinal intradural arachnoid cyst may present with paraparesis mimicking an intradural tumor, and lateral intrathoracic meningocele may seldom accompany this lesion. A comprehensive radiological examination must be conducted and a higher index of suspicion by neurosurgeons is necessary.

Abstract
METHODS During the last 5 years, 61 children were admitted to the authors' hospital because of corrosive substance ingestion, and among them 6 patients were seen with gastric outlet obstruction. Two of them had ingested acid substances, and the other 4 had ingested alkali corrosives. The mean age was 2.9 years (range, 1.5 to 3). Their common complaint was postprandial vomiting, which had begun 3 weeks after the event (range, 1 week to 10 weeks). Endoscopic evaluation and barium contrast radiographies were performed at admission. Four patients had a pyloric stricture, 1 had an antral stricture, and another had an antropyloric stricture. Balloon dilatation of the pylorus (in 1 patient), pyloroplasty (in 3 patients), and Billroth I procedures (in 2 patients) were performed. The mean follow-up period was 22 months (range, 6 weeks to 48 months). One patient, who had undergone a Billroth I procedure, underwent reoperation because of intestinal obstruction 3 months later. On follow-up they are all free of symptoms. CONCLUSIONS The treatment of gastric outlet obstruction caused by corrosive ingestion should be treated surgically. Although endoscopic and radiologic evaluation helps to determine the time and necessity, once the diagnosis is confirmed, early definitive surgical intervention should be performed, and the type of the surgery depends mostly on the findings of the surgeon at laparotomy. Endoscopic balloon dilatation of the pylorus maybe attempted in suitable cases. Special care should be given to prevent children from accidental corrosive ingestion.

Abstract
To investigate the association between the human leukocyte antigen (HLA) system and adhesions causing intestinal obstruction in childhood in order to determine whether HLA profiles can be used to identify and screen individuals at risk for intestinal adhesions, clinical and laboratory evaluations were done in a total of 42 (F:M = 27:15) patients. The mean age was 6.11 +/- 3.2 years (0.6-13 years). The patients were tested for HLA phenotype in two groups; the HLA phenotype distribution and relative risk (RR) for adhesions were determined. The study patients were children operated upon due to acute abdominal emergencies. Group 1 included patients who needed readmission after the surgery due to intestinal obstruction (n = 19), group 2 patients had no readmission for any reason following surgery (n = 23). Of the 19 patients in group 1, 9 were treated only medically and 10 needed surgical intervention. Among the patients in whom medical treatment was initiated (n = 14), 5 needed surgery during follow-up. There was an increased RR for certain HLA subtypes (A24 [9], HLA11, DR11 [5], B22) in patients presenting with intestinal obstruction due to adhesions. Among these, A24 (9) and DR11 (5) were statistically significant (P < 0.05) compared with the control group. Several possible mechanisms could link the HLA system with disease, especially those in which the immune response is suspected to be involved, but the questions of how the inflammatory response is initiated and the role of proinflammatory cytokines remain unclear. Future research developments are likely to focus on increased understanding of the molecular biology of the major histocompatibility complex and its biological function in the immune response and adhesion formation and intestinal obstruction. It is possible that HLA profiles can be used to identify individuals at risk for intestinal adhesions in the future.

Abstract
Colonic interposition is a treatment option in childhood when esophageal replacement (ER) is necessary. We reviewed 18 children who underwent ER by colon between 1984 and 1999. There were 5 with esophageal atresia and 13 with corrosive esophagitis; 15 had long-term follow-up (mean 38 months). Three procedures were performed by the Waterston technique and 12 by the retrosternal technique. ER was completed in a single stage in all but 1 patient. Pyloroplasty or antireflux surgery were not done routinely during colonic interposition. As early complications, we observed 11 cervical leaks and 2 pulmonary problems. As late complications, there were 4 redundancies, 3 gastrocolic refluxes, 2 cervical anastomotic stenoses, and 1 each intestinal obstruction due to adhesions, cologastric stricture, cosmetic deformity of the thorax, and bulging of the neck. Six patients with complications required secondary surgery. There were 4 deaths, 2 of them unrelated to the surgery. Cervical leakage, which was the most commonly observed problem, healed well. We believe the colon is still one of the best substitutes for the esophagus and that there is no need to perform a routine pyloroplasty or antireflux procedure as an adjunct to the primary surgery.

Abstract
The normally developing cardiovascular system of the chicken resembles that of the human. The purpose of the present study is to investigate some macroscopic and microscopic similarities between the chick and the human heart. For this study 20 adult and 10 newborn Broiler chickens were used. The heart and great vessels were routinely fixed in 10% formaldehyde in a phosphate buffer. Five adult and five newborn chicks hearts were embedded in paraffin. All section were examined by light microscopy. The atrioventricular valve of 15 adult chick hearts were examined macroscopically. While some structures previously reported were determined, two different properties of the mural leaf which are chordae tendineae in its posterolateral region anchoring at the right ventricle and its widening from the anterior to posterior commissure was also observed.

Abstract
In this study the reliability of anorectal manometry (ARMM) in Hirschsprung's disease (HD) in the neonatal period is evaluated. ARMM was performed in 59 patients (age ranging between 2 to 90 days) in whom HD was suspected. Rectal biopsy was performed in 23 newborn whose rectoanal inhibitory reflex (RAIR) was not identified in the ARMM study and in 13 RAIR-positive newborn due to strong clinical signs supporting HD or persistence of symptoms during their follow-up. Other RAIR-positive patients were followed up to 4 months to 3.5 years and no problems were encountered. Among the 36 newborn with rectal biopsies, if the results were compared to ARMM studies, there were one false-positive and two false-negative results. The sensitivity, specificity, positive predictive value, negative predictive value and accuracy of ARMM in the diagnosis of HD are 91.6%, 95.6%, 84.6% and 91.6% respectively. We conclude that ARMM can be used as a screening test in patients in whom HD is suspected during the neonatal period, but for definitive diagnosis it must be combined with other diagnostic tests.

Abstract
The records of 100 children with hydatid disease were reviewed retrospectively from 1978 to 1997; 43 were girls and 57 were boys. The mean age was 9.14 years; 61 patients had 124 hepatic cysts. Presenting symptoms were asymptomatic abdominal masses, found masses incidentally during ultrasonography (US), or acute abdomen. Plain X-ray films, US, or computerized tomography (CT) are sufficient for diagnostic evaluation in endemic areas. In the differential diagnosis, laboratory investigations such as the Casoni and Weinberg tests, indirect hemagglutination, eosinophilia, and ELISA were also used. These tests may give negative results, however, in some patients with hydatid disease. The mean follow-up time was 10.5 years (range 1-18 years), the mean duration of hospitalization 7 days. The complication rate was 3.6%. Mortality was 3.27% and occurred after the administration of formaldehyde and hypertonic scolicidal agents. Hydatid disease of the liver can be treated medically in selected patients; conservative surgical approaches that save as much parenchyma as possible, such as partial cystectomy and capitonnage, are indicated in the other cases.

Abstract
Three cases with foot drop following brain tumors in patients suffering from parasagittal pathology are reported. Foot drop was the first complaint in the patients in our series. We generally notice foot drop as a sign of lumbar disc herniation or peroneal nerve lesions but rarely foot drop may also occur with brain lesions.

Abstract
We present a case of a patient with multiple cerebral hydatidosis. We could not find any other origin of hydatidosis. In the light of the radiodiagnostic and biochemical findings, we assessed this case as a primary cerebral hydatidosis. The cysts were delivered completely. Two months after operation, the patient's neurological examination and control MRI were normal.

Abstract
Cushing's disease resulting from intrasellar gangliocytomas is very rare and only three cases have been reported to date. All of the cases were female. We present a fourth case of Cushing's disease resulting from intrasellar gangliocytoma. Computed tomography and magnetic resonance imaging scans showed a pituitary macrotumor with suprasellar extension. A greenish-gray colored homogenous tumor was subtotally removed by a transcranial approach. Histological diagnosis was gangliocytoma. To the best of our knowledge, this is the first reported instance of a tumor causing Cushing's disease in a man in the absence of a pituitary adenoma component.
