Modified 30-Degree Head-Up Tilt Park Bench Position in Semielective Posterior Fossa Surgery in a Patient with Pheochromocytoma

Von Hippel–Lindau (VHL) disease is a rare genetic disorder associated with the central nervous system and visceral organs. Pheochromocytomas occur in 10% of VHL patients, while cerebellar tumors are common tumors in VHL syndrome, with an incidence of 60%. The most common position for posterior fossa operations is the park bench or lateral decubitus position. These positions have primarily replaced the sitting position. However, the advantages of the supine position cannot be overlooked. The coexistence of pheochromocytoma and the cerebellar tumor may require modification in surgical position and anesthesia management in line with possible pathophysiological changes. We present the anesthesia management in posterior fossa surgery in patients with postponed pheochromocytoma surgery. The present case highlights the importance of a multidisciplinary team approach and anesthetic management

Enzymatic Characteristics and Growth Parameters of Ornamental Koi Carp (Cyprinus carpio var. Koi) Larvae Fed by Artemia Nauplii and Cysts

WOS: 000336248500014The purpose of this study was to compare the larval growth and digestive enzyme activities of koi carp (Cyprinus carpio var. Koi) larvae fed on Artemia nauplii (AN) and decapsulated cyst (ADC). The experiment was carried out in triplicate and lasted 27 days. Specific growth and survival rates, specific activities of total protease, lipase, amylase and chitinase were examined in experimental groups. At the end of the experiment for group fed with AN total length, weight and SGR were 20.56 +/- 3.23 mm, 0.9 +/- 0.05 g and 2.03 % d(-1), respectively and for group fed with ADC it was 28.16 +/- 4.81 mm, 0.28 +/- 0.16 g and 6.02 d (1) (P0.05). Besides, there were significant differences on specific enzyme activities (total protease, amylase, chitinase, lipase) (P<0.05). Obtained results suggested that koi larvae fed by ADC presented relatively higher growth parameters.Ege University, Scientific Research ProjectEge University [11-SUF-036]The authors kindly wish to thank the staff of the Orta Dogu Aquarium Inc., Bergama, Izmir, TURKEY where the experiments were conducted for their most efficient technical assistance and also the statistical valuation provided by Dr. Hulya Saygi is gratefully acknowledged.

Sedative Effect of Clove Oil and 2-Phenoxyethanol on Marine Clownfish (Amphiprion ocellaris) and Freshwater Swordfish (Xiphophorus helleri)

WOS: 000424964600033This study's objective was to determine effect of two different anaesthetics 2-phenoxyethanol and clove oil on the sedation of some aquarium fish species. The induction and recovery times were determined at five stages of melanistic and not melanistic clownfish (Amphiprion ocellaris) and different sexes of Swordfish (Xiphophorus helleri). Clownfish were tested with 0.4, 0.6 and 0.8 ml/l phenoxyethanol and 0.5, 1 and 1.5 ml/l clove oil. Swordfish were tested with 1, 3 and 5 ml/I phenoxyethanol and 2, 4, 6 ml/l clove oil. For short-term application the safe dose for clownfish was 0.4 ml/l phenoxyethanol and 1 ml/l clove oil. For swordtail fish, the ideal amount of phenoxyethanol was 5 ml/l and 6 ml/l clove oil. These safe doses reduce handling stress and mortality

Comparison of different tests to determine difficult intubation in pediatric patients

Background: The difficulties with airway management is the main reason for pediatric anesthesia-related morbidity and mortality. Objective: To assess the value of modified Mallampati test, Upper-Lip-Bite test, thyromental distance and the ratio of height to thyromental distance to predict difficult intubation in pediatric patients. Design: Prospective analysis. Measurements and results: Data were collected from 5 to 11 years old 250 pediatric patients requiring tracheal intubation. The Cormack and Lehane classification was used to evaluate difficult laryngoscopy. Sensitivity, specificity, positive predictive value and AUC values for each test were measured. Results: The sensitivity and specificity of modified Mallampati test were 76.92% and 95.54%, while those for ULBT were 69.23% and 97.32%. The optimal cutoff point for the ratio of height to thyromental distance and thyromental distance for predicting difficult laryngoscopy was 23.5 (sensitivity, 57.69%; specificity, 86.61%) and 5.5 cm (sensitivity, 61.54%; specificity, 99.11%). The modified Mallampati was the most sensitive of the tests. The ratio of height to thyromental distance was the least sensitive test. Conclusion: These results suggested that the modified Mallampati and Upper-Lip-Bite tests may be useful in pediatric patients for predicting difficult intubation

Comparison of Ontogenic Development and Digestive Enzymes in Ornamental Goldfish (Carassius auratus auratus L.) Larvae Fed with Decapsulated Cysts and Nauplii of Artemia

WOS: 000338176400011The purpose of this study is to compare the growth of goldfish, Carassius auratus auratus L. larvae fed on Artemia nauplii and, decapsuated cyst from 4 days after hatching (DAR) to 40 DAR In detail, specific growth and survival rates, specific activities of tote protease, lipase,. amylase, and chitinase were examined in both experimental groups. At. the end of the study, the highest survival rate was found in the group fed on cyst with 75.60+/-10.72% while the rate of the group fed on Artemia nauplii was found as 72.20+/-13.88%. Specific growth rate was calculated for larvae were-fed by Artemia nauplii and cyst as 11.59+/-8.92%d(-1) and 12.02+/-4.94%.d(-1), respectively. Total protease. activity presented: increased: profile during, the early ontogeny in both experimental group. The highest total protease specific activity was determined on day 34 as 3.81+/-0.26 U/mg protein(-1). in nauplii group. The maximum value for total protease (3.81+/-0.26 U.mg(-1) protein)' and lipase (557.38+/-24.77 mU/mg) specific activities were determined on day 34 in nauplii group (p>0.05). The peak of amylase (2.77+/-0.25 U.mg(-1) protein) and chitinase (769.27+/-74.74 mU.mg(-1) protein) specific activitdes were determined on day 34 in cyst group (p<0.05). Results of the study indicated that feeding, on decapsulated cyst contributed positively, to the larval development goldfish as much as Anemia: nauplii
