An Uncommon Complication of Septorhinoplasty, Acute Dacryocystitis

During septorhinoplasty procedures lacrimal drainage systems are susceptible to injury because of the close relationship of the nasal bones. Most of the injuries to the system remain asymptomatic. Here we report a case of septorhinoplasty which was complicated by acute dacryocystitis postoperatively. The patient was treated successfully with appropriate medical therapy.     

Evaluation of adipocytokines in obese children with insulin resistance

Obesity and overweight are among the most serious health problems in western societies and an increasing problem in developing countries. Recent studies indicate an important role of adipose tissue hormones, or "adipokines", in obesity-associated complications. To investigate the relation of two circulating adipokines (visfatin, adiponectin) with markers of insulin sensitivity and obesity in children, 40 obese children and 40 control children were recruited. Homeostasis model assessment for insulin resistance (HOMA-IR) and visfatin levels (4.99 +/- 2.08 vs. 1.47 vs. 0.7, p < 0.001; 31.3 +/- 11.1 vs. 18.5 +/- 10.7, p < 0.001, respectively) were significantly elevated and adiponectin levels (2.01 +/- 1.02 vs. 12.5 +/- 6.2, p < 0.001) were significantly lower in the obese group. Comparisons of the clinical and metabolic characteristics between insulin-resistant and noninsulin-resistant groups in obese children are summarized. The insulin-resistant group had higher visfatin levels (36 +/- 9.7 vs. 22.9 +/- 7.6, p < 0.001) and lower adiponectin levels (1.7 +/- 1.05 vs. 2.5 +/- 0.77, p: 0.016). Visfatin was correlated positively and adiponectin was correlated negatively with body mass index standard deviation score (BMI-SDS) and HOMA-IR. The role of various adipokines as connectors between obesity and diabetes mellitus has been better elucidated in recent years. Based on the findings of this study, visfatin and adiponectin levels can be used as specific markers for insulin sensitivity.     

Anoxybacillus salavatliensis sp. nov., an α-glucosidase producing, thermophilic bacterium isolated from Salavatli, Turkey

A novel moderately thermophilic, Gram-positive staining, rod-shaped, spore-forming, motile, facultative anaerobic, and α-glucosidase producing strain A343(T), was isolated from a high temperature well-pipeline sediment sample in Salavatli province of Aydin, Turkey. Growth was observed at 37-69 oC (optimum 60 °C), at pH 5.5-9.5 (optimum 8.0-9.0) and at salinities from 0 to 4.5% (w/v) (optimum 2%). Strain A343(T) was able to grow on a wide range of carbon sources. Gelatin and starch utilization, amylase, catalase and oxidase activities, reduction of nitrate to nitrite were all positive. The G+C content of the genomic DNA was 45.1 mol%. The major menaquinone was MK-7. The dominant cellular fatty acids were: iso-C15:0, C16:0, and iso-C17:0. The phylogenetic analysis based on the 16S rRNA gene sequence revealed that the strain A343(T) belonged to the genus Anoxybacillus. The 16S rRNA gene sequence similarity between strain A343(T) and the type strains of recognized Anoxybacillus species was ranged from 95.8 to 99.4%. DNA-DNA hybridization revealed low homology with its closest relative Anoxybacillus kamchatkensis (49.7%). In addition to the total cell protein profiles, the Rep-PCR and the intergenic 16S-23S rRNA gene fingerprinting profiles differentiated strain A343(T) from all of the reference Anoxybacillus species used. Based upon phenotypic, phylogenetic and chemotaxonomic evidence, strain A343(T) was assigned to a new species within the genus Anoxybacillus, A. salavatliensis sp. nov. (The type strain A343(T) = DSM 22626(T) = NCIMB 14579(T)). The 16S rRNA gene nucleotide sequence of strain A343(T) is available in the GenBank database under the accession number--EU326496.

Bilateral bifid mandibular condyle associated with ankylosis of the temporomandibular joint in a 6-year-old child

Bifid mandibular condyle with ankylosis is an extremely rare condition and may arise as a developmental or traumatic defect. We report here a case of bilateral bifid mandibular condyle with ankylosis in a 6-year-old child. The patient had severe limitation of mouth opening and history of trauma 2 years ago.
