Combined intraoral and nasal approach to Tessier No:0 cleft with bifid nose

The surgical correction of craniofacial clefts is an extremely difficult field in pediatric plastic surgery. Facial clefts are rare entities that most plastic surgeons will rarely have to manage. Various surgical techniques devised by some authors for facial clefts have not still widely accepted.The bifid nose deformity is generally an indicator of Tessier No:0 clefts, with various degrees of skeletal problems. The nasal roof area is an important key point in determining the appropriate surgical technique for reconstruction. In this report, a case of Tessier No:0 with a moderate nasal bifidity and ours novel surgical repair technique combining oral and nasal incision are presented.     

Second branchial anomalies in children

AIM: The aim of this study was to evaluate the data of our patients who had been treated for second branchial anomalies in the last 10 years. Here we report our clinical experience in second branchial anomalies with a review of the literature. PATIENTS AND METHODS: We evaluated retrospectively the data of 14 patients, who had been operated on between 1994 and 2004 for second branchial anomalies, in relation to age, sex, complaint at application, diagnostic test, surgical procedures and histopathologic findings. RESULTS: The mean age of the patients (8 female, 6 male) was 5.3 years (range = 1.5-16). The anomalies were usually located on the left side of the neck (n = 6). There were only 3 cases with bilateral anomalies. The majority of the lesions were sinuses (93%). The most frequent clinical feature was the presence of persistent discharge from an external (cutaneous) orifice. All lesions were excised by performing a second step ladder incision. Eight of the lesions were removed under the guidance of 3/0 polypropylene suture. No postoperative complication or recurrence was observed during the follow-up period. CONCLUSIONS: Second branchial arches anomalies are the most common branchial anomalies. Sinuses are more frequently encountered in children. Definitive treatment for these lesions is surgical excision. A polypropylene suture can be inserted into the tract as a guide to prevent incomplete excision.     

A semi-quantitative analysis of Fos expression by mustard oil

In the present study, a semi-quantitative analysis of Fos expression by mustard oil was performed. For this purpose, mustard oil was applied to the skin of the right hind foot of Wistar rats at various concentrations: 5%, 10%, 30%, 50%, 80% and 100% in liquid paraffin. The distribution and number of activated Fos-positive cells in the stimulated side (ipsilateral) and contralateral side of the spinal cord were investigated following the application. The ED50 of the response was also determined. The number of Fos-labelled cells gradually increased in a dose dependent manner in both sides of superficial layers (laminae I-II) of the spinal cord with increasing concentration of mustard oil. The increase between the doses was found significant in the ipsilateral superficial layers. The increase was significant in the contralateral superficial layers at concentrations above 50%. Very few Fos-labelled cells were observed around the central canal region in all concentrations. Higher doses of the mustard oil did not increase the number of activated cells in the deeper layers. However, the expression in the deeper layers (laminae III-X) does not show a consistent trend. Also, none of the concentrations used produced labelling in neurons of the deep ventral horn neurons or in motor neurons. Forty percent (40%) of mustard oil gave an approximately 1/2 maximum response i.e. an approximate ED 50. This may be important for studies using intrathecal application of antagonist following the mustard oil activation of skin nerve fibres.     

Increased nitric oxide is accompanied by lipid oxidation in adolescent varicocele

Summary One of the mechanisms of injury in varicocele has been proposed to be elevated nitric oxide (NO). We aimed to determine the association between the elevation of NO and lipid oxidation in varicocele compared with peripheral venous levels of these two substances as it has not been studied before. The study group consisted of 13 adolescents with left idiopathic varicocele of grades II-III. Blood specimens were obtained from dilated spermatic and peripheral veins simultaneously. Peripheral samples were also collected from 13 healthy children as controls. Nitrite/nitrate levels (NO(x)) and levels of malonedialdehyde (MDA) were determined using Griess reaction and thiobarbituric acid test, respectively. Results were compared with Kruskal-Wallis and Mann-Whitney tests. Peripheral NO(x) and MDA were the same in the study and control groups (p = 0.069 and p = 0.27, respectively). Spermatic vein NO(x) and MDA levels were elevated significantly compared with the peripheral levels in the study group (p = 0.005 and p = 0.048, respectively). Increased NO(x) levels with lipid oxidation occur locally in adolescent varicocele, implying that these events could be reversed by early treatment.     

A childhood case of intrascrotal neurofibroma with a brief review of the literature

Solitary neurofibroma unassociated with neurofibromatosis type I (NFI) arising within the scrotum is an extremely rare benign tumor. There are 8 cases reported in the literature with only 1 that occurred in childhood. In the current report the authors describe an additional adolescent patient, the second case encountered in childhood and the ninth case reported in the literature, together with a review of the related articles.     

Successful ivermectin treatment of hepatic strongyloidiasis presenting with severe eosinophilia

A 49-year-old, previously healthy nurse presented with hepatic lesions and severe peripheral eosinophilia due to strongyloidiasis. Imaging studies of the abdomen showed predominantly peripheral, confluent hepatic lesions. The hepatic lesions and eosinophilia did not show any improvement with albendazole, but completely resolved with ivermectin treatment. Our findings suggest that Strongyloides stercoralis can present with isolated focal hepatic lesions and severe eosinophilia, and resolves with ivermectin treatment.     

Synthesis of some 2-[(benzazole-2-yl)thioacetylamino]thiazole derivatives and their antimicrobial activity and toxicity

Some 2-[(benzazole-2-yl)thioacetylamino]thiazole derivatives (III) were synthesized by reacting 4-methyl-2-(chloroacetylamino)thiazole derivatives (I) with benzazol-2-thiole (II) in acetone in the presence of K(2)CO(3). The chemical structures of the compounds were elucidated by (1)H NMR and FAB(+)-MS spectral data. The prepared compounds were tested for antimicrobial activity and toxicity.
