A case of isolated sphenoid fungal sinusitis in an elderly diabetic patient is described. A coexisting mass lesion located in the sellar region was detected incidentally. Coincidence of these two entities represents a potential surgical disaster which may result in direct intracranial spread of fungal infection.

Background Gestational diabetes is defined as glucose intolerance which is first recognized in pregnancy. Oral glucose tolerance test (OGTT) is the cornerstone in diagnosing gestational diabetes. Placental elasticity evaluation is relatively new concept and is principally used for research purposes. We aimed to find any relation between placental elasticity evaluation and patients of gestational diabetes diagnosed by 75 g OGTT. Methods There were 91 patients took part in study, forming two groups as gestational diabetic patients (21 patients) and control group (70 patients). Elasticity of placenta was determined by acoustic radiation force impulse technology utilized by two blinded radiology specialists. Results We were not able to find any correlation between 75 g OGTT values and placental elasticity measurements (p > .05). Also placental elasticity was not found to be significantly different in two groups (p > .05). Conclusion Placental elasticity measurement on the 24th–28th weeks does not seem to be a marker for identification of gestational diabetes.

OBJECTIVES The aim of this study was to evaluate the feasibility of diffusion-weighted magnetic resonance, by comparing imaging in renal allograft recipients for functional assessment of kidney transplants versus imaging of these features in healthy volunteers and kidney donors with native kidneys. MATERIALS AND METHODS Seventy renal transplant recipients (group A) with stable graft function at postoperative month 1, 40 healthy volunteers (group B), and 40 kidney donors (group C) underwent diffusion-weighted magnetic resonance imaging. An echo-planar diffusion-weighted imaging sequence was performed in coronal orientation by using 6 b values (0, 200, 400, 600, 800, 1000 s/mm²). The apparent diffusion coefficients were determined for the upper and lower poles of the kidney cortex and medulla. Relations between apparent diffusion coefficients and allograft function, determined by the estimated glomerular filtration rate (comparing rates > 60 mL/min/1.73 m² [group A1] versus < 60 mL/min/1.73 m² [group A2]), were investigated in renal transplant recipients, and apparent diffusion coefficients in groups A, B, and C were compared. RESULTS Apparent diffusion coefficients were statistically higher in group A1 than in group A2 (P < .05) and statistically higher in group A than in groups B and C (P < .001). There were no significant differences between groups B and C (P > .05). CONCLUSIONS We observed that apparent diffusion coefficients of transplanted kidneys at postoperative month 1 were higher than values in native kidneys of healthy volunteers and kidney donors. In addition, apparent diffusion coefficients of transplanted kidneys with estimated glomerular filtration rates > 60 mL/min/1.73 m² were higher than transplanted kidneys with rates < 60 mL/min/1.73 m².

Objective: Nonalcoholic fatty liver disease is the most common cause of liver dysfunction in Western countries and an independent risk factor for atherosclerotic heart disease. Appropriate noninvasive parameters are lacking for optimal risk stratification of cardiovascular disease in these patients. We evaluated several recently discovered noninvasive parameters for atherosclerosis in patients with nonalcoholic fatty liver disease: epicardial fat thickness, aortic flow propagation velocity, and osteoprotegerin level. Methods: Forty-one patients (27 men and 14 women; mean age, 37.9±8.9 years) with nonalcoholic fatty liver disease and 37 control subjects (17 men and 20 women; mean age, 34.5±8.6 years) were enrolled in this observational case-control study. Patients with nonalcoholic fatty liver disease diagnosed at a gastroenterology outpatient clinic were included. Patients with cardiac pathology other than hypertension were excluded. Epicardial fat thickness and aortic flow propagation velocity were measured by echocardiography. The serum concentration of osteoprotegerin was measured using a commercial enzyme-linked immunosorbent assay kit. Results: Nonalcoholic fatty liver disease patients exhibited a significantly lower aortic flow propagation velocity (155.17±30.00 vs. 179.00±18.14 cm/s, p=0.000) and significantly higher epicardial fat thickness (0.51±0.25 vs. 0.29±0.09 cm, p=0.000) than control subjects. Osteoprotegerin levels were higher, but not significant, in patients with nonalcoholic fatty liver disease (28.0±13.0 vs. 25.2±10.8 pg/mL, p=0.244). Binary logistic regression analysis showed that aortic flow propagation velocity (OR, –0.973; 95% CI, 0.947–0.999) and waist circumference (OR, –1.191; 95% CI, 1.088–1.303) were independent predictors of nonalcoholic fatty liver disease. Conclusion: In this study, epicardial fat thickness and osteoprotegerin level were higher and aortic flow propagation velocity was lower in patients with nonalcoholic fatty liver disease. Early detection of abnormal epicardial fat thickness and aortic flow propagation velocity may warrant a search for undetected cardiovascular disease in patients with nonalcoholic fatty liver disease.

Tail Gut Kisti â" Retrorektal Kitl Özçelik; Hüseyin Yüce Bircan; Halime Çevik; Şemsi Altaner; Alp Demirag
Tail gut cysts are rare congenital lesions located in retrorectal area arising from the vestiges of the embryonic hindgut and often present in middle-aged women with perirectal symptoms. Although tail gut cysts are usually benign congenital lesions, malignant transformation has been rarely reported. In this case report we present a 48year-old woman who was admitted to hospital with an asymptomatic palpable perirectal mass for two months. The radiological appearance of tail gut cyst was three lobulated and it was successfully excised with combined perineal and abdominal approaches.
