RESUMO
Bertiella spp. is a mite-borne cestode parasite that inhabits the small intestine of wide range of mammals, including non-human primates. In the present study, the morphological and molecular analysis of Bertiella studeri recovered from the small intestine of a bonnet macaque (Macaca radiata) from Wayanad, Kerala (South India) was performed. Acetic alum carmine staining identified the cestode morphologically based on the characters like broader proglottids, which contain irregularly alternating genital pores, single set of reproductive organs, 280 testes and a tubular transverse uterus. Molecular characterization was done using 18SrRNA, ITS1-5.8S and COX1 genes. Phylogenetic trees were constructed using MEGA X based on the Maximum Likelihood (ML) method (Hasegawa-Kishino-Yano (HKY) model). Cytochrome oxidase I gene could detect the existence of genetic variation in the parasite from two different hosts viz., monkey (Kerala, Argentina, and Kenya) and human (Sri Lanka). A minimum spanning network of haplotypes was generated by the haplotype networking with the above sequences using the popARTv1.7. Haplotype analysis based on COX1 revealed that the parasite haplotype was different in each country with highest population frequency in Sri Lanka.
RESUMO
Malperfusion of end organs occurs in 20% to 40% patients with acute type A aortic dissection. Because irreversible ischemia is a time-dependent event, expedient diagnosis and treatment are necessary. We herein report successful surgical management of a patient with acute type A aortic dissection causing transient gut ischemia and a rare gall bladder perforation. We implemented one-stage surgical and laparoscopic management approach for the diagnosis and treatment. Increased awareness of this complication and appropriate use of available diagnostic tools may improve the outcome in similar patients. Patients with aortic dissection complicated by visceral ischemia require a prompt sequential and rational multidisciplinary approach for successful management.
