The profile of hemolymph ecdysteroid was studied in the gram pod borer, Helicoverpa armigera, during larval-pupal transformation. The changes closely correspond to the developmental events occurring at metamorphosis. Two insect growth regulators, plumbagin and azadirachtin, significantly depleted the content and altered the profile of ecdysteroids at crucial stages, when applied at ED50 doses. The activity profiles of two fat body lysosomal enzymes, acid phosphatase and b-galactosidase, were also significantly affected by the insect growth regulators. It is suggested that plumbagin and azadirachtin treatments primarily modify the ecdysteroid titer, which in turn leads to changes in lysosomal enzyme activity causing overt morphological abnormalities during the metamorphic molt., Arulappan Josephrajkumar, Bhattiprolu Subrahmanyam, Srinivasan, and Lit
Only a few cases of pneumocystis pneumonia (PCP) in Cushing’s syndrome have been published in the literature so far. In the majority of these patients, the pneumonia occurred after reduction of the hypercortisolism with medicamentous treatment. We report two cases of PCP during conservative treatment of hypercortisolism. We describe clinical, imaging and laboratory findings in two patients and review published cases of pneumocystits pneumonia in Cushing’s syndrome. A 60-year-old woman and 20-year-old man with Cushing’s syndrome due to ectopic ACTH syndrome were treated at our department. Both developed pneumocystis pneumonia early after treatment with ketoconazole and ethomidate bromide had been introduced and the levels of cortisol rapidly decreased. PCP prophylaxis in patients with high cortisolemia should be started before treatment of hypercortisolism in current practice. Gradual lowering of plasma cortisol should also reduce the risk of infection by Pneumocystis jiroveci., Filip Gabalec, Alžběta Zavřelová, Eduard Havel, Jaroslav Cerman, jr., Jakub Radocha, Ioannis Svilias, Jan Čáp, and Literatura 10
INTRODUCTION: Hirschsprung's disease is a congenital colonic aganglionosis, usually presented as inability or difficulty in passing of meconium, chronic and persistent obstipation, maleficent feeding, vomiting, distension and lethargy. CASE PRESENTATION: We presented a case of an in-vitro conceived quadruplet premature neonate who presented with pneumoperitoneum caused by transverse colon spontaneous perforation and microcolon appearance of distal bowel, treated by resection and temporary colostomy turns to be a rare manifestation of Hirschsprung's disease. CONCLUSION: Assisted reproductive technologies increases chances for multiple pregnancies and may increase chance for major congenital anomalies. Rare manifestation of Hirschsprung's disease is spontaneous pneumoperitoneum which remains a surgical emergency. Delay in recognizing and treatment can significantly worsen prognosis. In neonate with intestinal perforation one should consider Hirschsprung's disease. and J. Mihanović, I. Jurić, Z. Pogorelić, I. Mrklić, M. Jukić, D. Furlan
