Comparison of Limberg flap and excision and primary closure of pilonidal sinus disease, in terms of quality of life and complications

Purpose: The aim of this study was to compare two different treatment methods for pilonidal sinus with respect to complications, recurrence, and patient quality of life. Methods: Five hundred forty-nine patients who underwent surgery for pilonidal sinus between January 2007 and August 2012 were included in thi s study. The patients were classified into group I (excision and primary closure) and group II (Limberg f lap). Results: There was no significant difference in the mean age and gender of t he patients between groups I and II (P = 0.512 and P = 0.472). The duration of surgical operation was lower in group I (P < 0.001). There was no significant difference in hospitalization time after surgery, minor complications, and recurrence between the groups (P = 0.674, P = 1.000, and P = 1.000, respectively). The time required for pain-free walking, urinating, and returning to work was significantly lower in group II (P < 0.001, P < 0.001, and P < 0.001, respectively). The patients in group I stated that they were more satisfied in terms of aesthetics (P < 0.001). Conclusion: According to the results of this study, Limberg flap method has better outcomes compared with excision and primary closure. Therefore, we recommend Limberg f lap for treatment of pilonidal sinus disease. Copyright © 2013, the Korean Surgical Society

Effects Of Limnoecological Changes On The Ostracoda (Crustacea) Community In A Shallow Lake (Lake Cubuk, Turkey)

We sampled Lake Cubuk, a shallow lake in Bolu (Turkey), for 26 months to investigate the effect of limnoecological changes on the composition of ostracod species. Seventeen ostracod species were identified from the six stations sampled between 2008 and 2010. Numbers of species and individuals were both significantly reduced during 2010, which corresponded to a 3 m water level increase. Ostracod Watch Model (OWM) displayed distinct seasonal occurrences of five species (Candona neglecta, Cypria ophtalmica, Cypridopsis vidua, Limnocythere inopinata, Fabaeformiscandona cf. japonica) when Physocypria kraepelini was the only species encountered all year round. Approximately 77.2% of the relationship between species and environmental variables was expressed by the first two axes of Canonical Correspondence Analysis (CCA). Electrical conductivity and water temperature (P=0.002) were the most influential variables on species. There was a significant negative correlation of seven species to conductivity. Of those (F. cf. japonica and C vidua) showed a significant positive correlation to water temperature, while C. candida was negatively correlated to water temperature (P<0.05). C. neglecta was the only species to show a positive correlation to dissolved oxygen. Tolerance limits for the most common species were higher than the mean water temperatures, but lower than mean levels of electrical conductivity. Finding the ratio of noncosmopolitan to cosmopolitan species "pseudorichness" as 1.13 suggested significant role of cosmopolitan species to species diversity. (C) 2014 Elsevier GmbH.
