Ornithine carbamoyl transferase (OCT) activity and other liver function tests were studied in a total of 50 patients of clinical malaria and 15 controls. They were grouped as group I (positive for malarial parasite on peripheral blood smear, n=18), group II (negative for malarial parasite on peripheral blood smear (PBS) but responded to antimalarials, n=17) and group III (peripheral blood smear negative and did not respond to antimalarial therapy, n=15). The mean OCT levels were significantly raised in group I (6.79 ± 1.84 IU/L, p value = 0.006) and group II (5.0 ± 1.15 IU/L, p value = 0.014) as compared to controls (2.5 ± 1.13 IU/L) and returned to normal after treatment In contrast, group III had normal levels except in a case of kala azar and septicemia where OCT levels were high and increased further on treatment. Taking PBS positivity as a gold standard of diagnostic criteria, OCT had a sensitivity of 83% and specificity of 86% with a high positive predictive value of 88% as compared to ALT which had a lower sensitivity of 55% and specificity of 80%. The clinical response rate in PBS negative cases of fever having high OCT level was 83% as compared to 35% in cases with normal OCT level, making OCT a good surrogate marker of malaria. OCT levels could also be of prognostic significance as 2 cases of cerebral malaria had high OCT levels of 11.1 UAL and 10.7 IU/L, respectively.Key Words: Malaria, Ornithine carbamoyl transferase 相似文献

Background
Racial disparities in incidence of colorectal cancer (CRC) exist. In Hispanics, CRC was the second most commonly diagnosed cancer in 2012.Methods
We abstracted the national estimates for Hispanics/Whites with CRC using the SEER database between 2000 and 2010. Trends in incidence, mortality, gender and stage of disease were analyzed for early-onset (age<50; EO - young) and late-onset (age>50; LO - old) cases.Results
The overall incidence of CRC increased by 48% in Hispanics. 38% increase in incidence of LO CRC and 80% increase in incidence of EO CRC was seen in this ethnic group. Hispanics and Whites showed higher percentage of distant tumors for both age groups. There was no deviation in overall trend between males and females.Conclusions
Although there is an overall decrease in incidence of CRC in Whites increase was seen in Hispanics. While incidence of EO CRC is increasing in both races, LO CRC incidence is increasing in Hispanics not in Whites. This data suggest that disparities in incidence of EO and LO CRC exist between Hispanics and Whites. 相似文献5.

Spectrin-alpha I/61: a new structural variant of alpha-spectrin in a double-heterozygous form of hereditary pyropoikilocytosis 总被引:3,自引:0,他引:3
Recent biochemical studies have led to the identification of abnormal spectrins in the erythrocytes of patients with hereditary pyropoikilocytosis (HPP) and hereditary elliptocytosis (HE). In this report we describe the biochemical characterization of the erythrocytes from a proband with severe HPP who is doubly heterozygous for two mutant spectrins (Sp): Sp alpha I/74 and a new, previously undetected, mutant of alpha-spectrin designated Sp alpha I/61. The proband's erythrocytes are unstable when exposed to 45 degrees C, and her membrane skeletons exhibit instability to shear stress. The content of spectrin in the proband's erythrocyte membranes is decreased to 75% of control values. The amount of spectrin dimers in crude 4 degrees C spectrin extracts is increased (58%) as compared with control values (6% +/- 4%). Limited tryptic digestion reveals a marked decrease in the normal 80,000-dalton alpha I domain, an increase in the 74,000-dalton fragment that is characteristic of Sp alpha I/74, and an increase in a series of new fragments of 61,000, 55,000, 21,000, and 16,000 daltons. Both parents are asymptomatic, but they have increased amounts of spectrin dimers (17% to 25%). Limited tryptic digestion of the father's spectrin demonstrates the presence of a previously identified abnormal spectrin (Sp alpha I/74) that is characterized by a decrease in content of the 80,000-dalton peptide and an increase in concentration of the 74,000-dalton peptide. The mother's spectrin digests show a decrease in the amount of 80,000-dalton peptide and the formation of new peptides of 61,000, 55,000, 21,000, and 16,000 daltons. The data indicate that this severe form of HPP is due to the inheritance of two distinct abnormal spectrins, Sp alpha I/74 and a new spectrin mutant, Sp alpha I/61. 相似文献

Postoperative pneumoperitoneum poses a clinical dilemma.Depending on the cause,its management includes a spectrum from simple observation and supportive care to surgical exploration.The aim of this paper is to present four clinical cases and propose an algorithm for the management of postoperative pneumoperitoneum based on available literature.The causes,diagnosis and possible complications arising from pneumoperitoneum will also be discussed.Three of the four cases presented were successfully managed conservatively and one had an exploratory laparotomy with negative findings.In such scenarios,it is important to consider the nonsurgical causes of pneumoperitoneum,which include pseudopneumoperitoneum,thoracic,abdominal,gynecological and idiopathic.These causes do not always require emergent exploratory laparotomy.The surgical team needs to consider the history,physical exam and diagnostic workup of the patient.If a patient presents with peritoneal signs,then exploratory laparotomy is a must.Since 10%of the cases of pneumoperitoneum are caused by nonsurgical entities,managed expectantly,a negative exploratory laparotomy and its associated risks are avoided. 相似文献
