    Prevalence of testicular microlithiasis in an asymptomatic population
    Serter, S; Gümüs, B; Ünlü, M; Tunçyürek, Ö; Tarhan, S; Ayyildiz, V; Pabuscu, Y
    Objective. Testicular microlithiasis is a rare, usually asymptomatic, finding of the testes associated with various genetic anomalies and infertility. It is also widely believed that testicular microlithiasis is strongly associated with testicular tumor. The aim of this prospective study was to determine the true prevalence of testicular microlithiasis in an asymptomatic population by means of ultrasound screening. Material and methods. Healthy male volunteers (17-42 years old) were recruited from the annual Army Reserve Officer Training Corps training camp at Manisa, Turkey. A screening genitourinary history was obtained and a physical examination and screening scrotal ultrasound scan were performed. All men diagnosed with testicular microlithiasis underwent complete clinical evaluations, physical examinations and determination of tumor markers. Results. Fifty-three men with testicular microlithiasis were identified from the 2179 ultrasound scans, giving a prevalence of testicular microlithiasis of 2.4% in this asymptomatic population. The age (mean +/- SD) of subjects with testicular microlithiasis was 23.9 +/- 4.2 years (range 20-31 years). Conclusion. Our results suggest that there is no significant association between TM and testicular cancer, although it is difficult to rule out such an association without further studies with a longer follow-up period.

    Computed Tomographic Reversal Sign in an Adult with Methanol Intoxication
    Tunçyürek, Ö; Tarhan, S; Örgüç, S; Atalar, M; Sener, RN
    The computed tomographic (CT) reversal sign is associated with diffuse, anoxic/ischemic cerebral injury, and is seen almost exclusively in children, and only one adult patient with meningitis exists in the literature with this sign. On the other hand, methyl alcohol intoxication is usually associated with bilateral putaminal necrosis, and no CT reversal sign has been observed before in this condition. This report presents an adult patient with methyl alcohol intoxication, and the CT reversal sign.

    CT and MRI examinations left behind in the radiology department
    Göktan, C; Pekindil, G; Örgüc, S; Tunçyürek, Ö; Bayindir, P; Öner, M
    PURPOSE To retrospectively document the reported computerized tomography (CT) and magnetic resonance imaging (MRI) examinations that were left behind in our radiology department, to calculate their cost, and to determine possible sources of waste in order to draw attention to this subject. MATERIALS AND METHODS The reported and billed CT and MRI examinations for 2003 that were not taken from the radiology department were documented, and the percentage they represented of all CT and MRI performed that year were determined. The total cost of the examinations, including contrast media, was calculated. RESULTS In all, 200 CTs out of 4390 and 95 MRIs out of 7003 were left behind in the radiology department during 2003. Total cost of the examinations, including the contrast media, was 31,320 YTL. CONCLUSION The percentages of CT and MRI examinations left behind in the radiology department were evaluated in this preliminary report. Since we did not find any similar study in the literature, we could not comment on the limits of acceptability of the results; however, we think other radiology departments should determine the percentages CTs and MRIs that are left behind and take the necessary precautions to minimize waste and reduce expenses.

    Sonographic evaluation of spleen size and prevalence of accessory spleen in a healthy male Turkish population
    Serter, S; Ceylan, C; Tunçyürek, Ö; Örgüc, S; Pabuçcu, Y
    Objective: It is known that the measurement of splenic length in routine clinical practice is a very good indicator of actual splenic size. Knowledge of the normal range of spleen size in the population being examined is a prerequisite. Racial differences in splenic length could result in incorrect interpretation of splenic measurements. The purpose of this study was to establish the range of spleen length in a young male Turkish population. Material and Methods: A total of 2179 volunteers, healthy men aged 17-42 years, from the annual Army Reserve Officer Training Corps training camp at Manisa were included in the study. Sonographic measurements of spleen length were performed on 2179 military personnel. Presence of accessory spleen was also determined. In addition, the height, weight, and age of each volunteer were recorded. Using linear regression analysis, the relation of spleen length and body height, weight and body mass index (BMI) was evaluated. Additionally, the prevalence of accessory spleen detected on ultrasound was calculated. Results: The mean +/- SD height was 173,1 +/- 6,5 cm, mean weight 69,1 +/- 9,7 kg, and mean BMI 22,62 +/- 2,87. Mean spleen length was 10,76 +/- 1,8 cm. The length of the spleen was below 12,80 cm in 95% of the subjects. No statistically significant correlation (p<0.01) between spleen length and body height, weight and BMI was found. The prevalence of accessory spleen was determined as 2.5% on ultrasound screening. Conclusion: It was found that in healthy Turkish men, mean spleen length was 10,76 1,8 cm. This data should be taken into consideration when the diagnosis of splenomegaly is established in Turkish males. (Turk,l Hematol 2010; 27: 25-8)
