ObjectiveWe wanted to compare the efficacies of 95% ethanol and 20% hypertonic saline (HS) sclerotherapies that were performed in a single session under CT guidance for the management of simple renal cysts.Materials and MethodsA prospective series of 74 consecutive patients (average age: 57.6 ± 8.1 years) with simple renal cysts were enrolled in this study. They were randomized into two groups and 95% ethanol or 20% HS, respectively, corresponding to 25% of the aspiration volume, was injected. Treatment success was determined six months later with follow-up clinical evaluation and performing ultrasonography.ResultsThe sclerotherapy was accepted as technically successful without major complications in all except two patients who were excluded because of a communication between the simple renal cyst and the pelvicalyceal collecting system. Thirty-six patients in the ethanol group received sclerotherapy with 95% ethanol and 36 patients in the HS group underwent sclerotherapy with 20% HS. The complete regression ratio of the ethanol group was significantly higher (94% versus 72%, respectively) than that of the HS group. There was one patient with partial regression in each group. The failure ratio of the ethanol group was significantly lower (3% versus 25%, respectively) than that of the HS group.ConclusionEthanol sclerotherapy under CT guidance is a successful and safe procedure and it can be used for the treatment of simple renal cysts. Sclerotherapy with 95% ethanol is more effective than 20% HS sclerotherapy. Sclerotherapy with HS may be an option for patients preferring to undergo a less painful treatment procedure.

Context: Morus nigra L. (Moraceae) has various uses in traditional medicine. However, the effect of M. nigra on cognitive impairment has not been investigated yet. Objective: The objective of this study is to determine the phenolic acid content and DNA damage protection potential of M. nigra leaf extract and to investigate the extract effect on cognitive impairment and oxidative stress in aging mice. Materials and methods: Phenolic acid content was determined by quantitative chromatographic analysis. DNA damage protection potential was evaluated on pBR322 plasmid DNA. Thirty-two Balb-C mice were randomly divided into four groups (control, D-galactose, D-galactose + M. nigra 50, and D-galactose + M. nigra 100). Mice were administered D-galactose (100 mg/kg, subcutaneous) and M. nigra (50 or 100 mg/kg, orally) daily for 8 weeks. Behavioral responses were evaluated with Morris water maze. Activities of antioxidant enzymes and levels of malondialdehyde (MDA) were assayed in serum, brain, and liver. Results: In extract, vanillic (632.093 mg/g) and chlorogenic acids (555.0 mg/g) were determined. The extract between 0.02 and 0.05 mg/mL effectively protected all DNA bands against the hazardous effect of UV and H 2 O 2 . Morus nigra significantly improved learning dysfunctions (p 50.01), increased memory retention (p50.01), reduced MDA levels (p50.05), and elevated SOD, GPx, and CAT activities (p50.05) compared with the D-galactose group. Discussion and conclusion: These results show that M. nigra has the potential in improving cognitive deficits in mice and that M. nigra may be useful to suppress aging, partially due to its scavenging activity of free radicals and high antioxidant capacity. ARTICLE HISTORY

Syndactyly type I is an autosomal dominant condition with complete or partial webbing between the third and fourth fingers or the second and third toes or both. We report here a previously undescribed phenotype of severe mesoaxial syndactyly and synostosis in patients born to affected parents. The characteristic features of these severe cases are (1) complete syndactyly and synostosis of the third and fourth fingers; (2) severe bone reduction in the proximal phalanges of the same fingers; (3) hypoplasia of the thumbs and halluces; (4) aplasialhypoplasia of the middle phalanges of the second and fifth fingers; and (5) complete or partial soft tissue syndactyly of the toes. We report on three offspring with this phenotype from two different branches of a syndactyly type I family, suggesting that they may be homozygous for this condition. SSCP and linkage analysis indicated that neither HOXD13 nor other relevant genes in the chromosome 2q31 region was responsible for this phenotype. (7 Med Genet 1998;35:868-874)

With the objective of creating standards for the volume of the thyroid gland by ultrasonography in the 0-16-year age group, thyroid volumes of 302 healthy children (150 boys, 152 girls) were measured by ultrasonography. The transverse (x), sagittal (y) and anteroposterior (z) lengths of the right and left lobes and isthmus were measured. Volumes of these were calculated by the ellipsoid volume formula [V = (pi/6) x x x y x z]. Statistical analysis was done using the Kruskal-Wallis and Student t tests. The cases were divided into six and eight groups by age and height, respectively. There was a significant positive correlation between thyroid volume, age, height and weight. Thyroid volumes in children of 12 years and over were significantly different from those in the younger age groups.

CT-guided PCN is an efficient and safe procedure with major and minor complication rates below the accepted thresholds. It can be used for the management of patients requiring nephrostomy insertion in inpatient settings, and might be a preferable procedure in patients with minimal or no dilatation of the renal pelvis.
