ABSTRACT
Background: The role of AST/ALT ratio in prognostication of cancer cervix is not established in different study settings except for very few where they have highlighted on circulation of higher levels of AST and ALT in the cervical cancer patients. Moreover, there is a biological plausibility explained in one of the studies hence the study was conducted to elicit if the AST/ALT ratio could predict the prognosis of advanced cancer cervix before the initiation of treatment. Methodology: A follow up study was conducted among 122 newly diagnosed locally advanced carcinoma cervix patients in a regional cancer centre Bangalore from June 2015 to May 2018. All the basic data, normal and abnormal levels of serum Aspartate transaminase (AST), Alanine transaminase (ALT) and AST/ALT ratio were collected, followed up for one year and compared for overall survival using Log-rank test along with Kaplan-Meir curves. Receiver Operator Characteristic curves (ROC curves) were plotted to determine the poor outcome (death). Data was analysed using SPSS 18.0 and P value < 0.05 was considered statistically significant. Results: The mean age of the study participants was 50.4±10.6years. Mean follow up period was 4±3 months (1-12 months). Median serum AST, ALT and de-ritis ratio did not differ among the different stages of cervical cancer. Area under the curve (AUCs) for de-ritis ratio was found to be not significant with very poor accuracy (AUC = 0.47;P> 0.05). It was observed that there was no statistically significant difference between the groups in their survival rates. Conclusion: AST/ALT ratio cannot predict the prognosis of advanced cancer cervix before the initiation of treatment.
ABSTRACT
Background: Diabetes mellitus is associated with many cardiovascular dysfunction and impairment of potassium channel function. Aim: We compared the vascular reactivity in aorta from streptozotocin-induced and Goto-Kakizaki (GK) diabetic rats to potassium channel openers. Methodology: Diabetes mellitus (DM) was induced in Sprague Dawley rats by intraperitoneal injection of streptozotocin (STZ) at 65 mg/kg body weight. After four weeks of DM, vascular reactivity of the aortic rings from STZ-induced Sprague Dawley and age-matched GK and control rats to phenylephrine, acetylcholine, levcromakalim and naringenin was studied using standard organ bath procedure. Results: The phenylephrine-induced contraction was significantly (P<0.05) increased in STZ-diabetic aortic rings [2.03 ±0.07 g] when compared with GK rats [1.47±0.14 g] and STZ-control [1.42±0.21 g]. Maximal relaxation and potency to acetylcholine, levcromakalim and (+/-)-naringenin were significantly (P<0.05) decreased in STZdiabetic aorta when compared with GK-diabetic and control groups. Conclusion: The phenylephrine-induced contraction, endothelium-dependent relaxation, KATP - and (+/-)-naringenin-induced vasorelaxation are not altered in the early stages of Type 2 diabetes whereas there is exaggerated contractile response and a relaxant dysfunction involving the endothelium, KATP in Type 1 diabetes mellitus.
ABSTRACT
Se presenta el caso de un lactante menor que fue etendido en el nosocomio por intoxicación aguda por hierro. Se detalla la evolución del cuadro clínico del paciente y se discute el caso de acuerdo a las normas vigentes en este tipo de intoxicaciones. Por otro lado, se plantea en un cuadro la evolución clínica de este tipo de pacientes y finalmente se propone un flujograma para el abordaje, diagnóstico y manejo de la intoxicación aguda por hierro en pediatría.
