ABSTRACT

Contexto y objetivo: las anomalías hematológicas se encuentran entre las complicaciones más comunes de la infección por el VIH. También se han realizado bastantes estudios sobre las alteraciones en el perfil de lípidos, aunque los resultados en gran medida no han sido concluyentes. El presente estudio se llevó a cabo para evaluar el recuento de células CD4 y el perfil de lípidos en los pacientes infectados por el VIH y el SIDA en la población india y los correlaciona con los controles sero-negativos. Materiales y métodos: El presente estudio fue diseñado como un estudio transversal, con base en un hospital, para evaluar el recuento de células CD4 y el perfil de lípidos en los pacientes infectados por VIH y SIDA en la población india y los correlaciona con los controles sero-negativos. La evaluación del perfil de lípidos se realizó utilizando Erba EM 360, un analizador automático impulsado por un fotómetro de rejilla de difracción, mientras que los recuentos de células CD4 se evaluaron utilizando el Contador de ciclo de Partec. Análisis estadístico utilizado: Los datos se analizaron con SPSS versión 15.0 (SPSS Inc., Chicago, IL, EE. UU.). La comparación de dichos parámetros se realizó mediante el análisis de varianza (ANOVA) y la prueba post-hoc de Games-Howell. Se consideró estadísticamente significativo un valor de p <0,05. Resultados: Los niveles de colesterol total y lipoproteínas de baja densidad (LDL) disminuyeron significativamente, mientras que los triglicéridos y las lipoproteínas de muy baja densidad (VLDL) aumentaron significativamente en los pacientes infectados por VIH y SIDA en comparación con los controles sero-negativos. Conclusión: El colesterol total, las LDL, los triglicéridos y las VLDL se alteraron significativamente en los pacientes infectados por VIH y con SIDA en comparación con los controles sero-negativos


Context and Aim: Hematological abnormalities are amongst the most common complications of infection with HIV.There have been quite a few studies on the alterations in lipid profile, too, though the results have largely been inconclusive. The present study was carried-out to assess CD4 cell counts and lipid profile in the HIV infected and AIDS patients in the Indian population and correlates them with the sero-negative controls. Materials and Methods: The present study was designed as a cross-sectional, hospital-based study to assess CD4 cell counts and lipid profile in the HIV infected and AIDS patients in the Indian population and correlates them with the sero-negative controls. Evaluation of lipid profile was done using Erba EM 360, an automated analyzer powered by a diffraction grating photometer while CD4 cell counts were evaluated using Partec Cyflow Counter. Statistical analysis used: The data was analyzed using SPSS version 15.0 (SPSS Inc., Chicago, IL, USA). Comparison of the said parameters was done using Analysis of Variance (ANOVA) and post-hoc Games-Howell test. p-value of <0.05 was considered statistically significant. Results: The levels of total cholesterol and low-density lipoproteins (LDLs) were significantly decreased while triglycerides and very low density lipoproteins (VLDLs) were significantly increased in the HIV infected and AIDS patients when compared with the sero-negative controls. Conclusion: Total cholesterol, LDLs, triglycerides and VLDLs were significantly altered in the HIV infected and AIDS patients when compared with the sero-negative controls

ABSTRACT

CONTEXT: The single most important factor that is known to improve the end result of head and neck cancer is the early diagnosis of these cancers while they are still localized and can be treated with a high probability of cure. Early diagnosis of cancer plays a lifesaving pivotal role in overall management. The technique of colposcopy enables evaluation of changes in surface topography and vascular patterns of the lining mucosa thus, aiding in selecting the most appropriate site of biopsy ruling out the possibility of taking biopsy from the most representative area supposed to reveal epithelial dysplasia. In view of the intra-oral application of micro-colposcopy, it was felt that colposcopy might provide a useful aid for the early enough diagnosis of oral precancerous and cancerous lesions and conditions affecting the oral mucosa to improve the prognosis. AIMS: To clinicopathologically correlate cases of oral precancers; correlate the surface characteristics revealed by micro-colposcopy with the histopathological diagnoses of the sites under observation; and map out the areas of surface dysplasia to indicate the full extent of epithelial changes before taking the biopsy specimen to take specimen from areas most representative of dysplasic features (guided biopsies). MATERIALS AND METHODS: A total 90 subjects were studied including 30 cases of oral submucous fibrosis, 20 cases each of hyperkeratotic lesions including homogeneous and nonhomogeneous leukoplakias and oral lichen planus and 20 cases of clinically diagnosed and histopathologically proven oral squamous cell carcinoma. RESULTS: In this study, a sensitivity of colposcopic screening test came-out to be about 71% while specificity was about 91%. Positive predictive value was 91%. CONCLUSION: Although the degree of abnormality in colposcopic findings can be predicted by the vascular patterns of the lesion, the major advantage of colposcopy is to outline the most suspicious lesion for histologic diagnosis by directed biopsy, which is the mainstay in establishing the correct diagnosis. Colposcopy is valuable in the detection of early cancerous lesions. However the final diagnosis must rely on a meticulous histopathological examination by an expert pathologist.

ABSTRACT

BACKGROUND: There have been studies that report clinical benefits of the use of folic acid as an adjuvant to the antiepileptic therapy in the prevention of antiepileptic drug-induced gingival enlargement. However, studies in the past have also reported precipitation of epileptic attacks in patients on folic acid adjuvant therapy due to fall in sera levels of phenytoin due to drug interactions. The study was planned to investigate the association of phenytoin-induced gingival enlargement and sera levels of folic acid in epileptic patients on phenytoin therapy. The statistical analysis was done using t-test and the baseline serum folate levels and the serum folate levels obtained after 6 months of phenytoin therapy were correlated with the respective grades of gingival enlargement using Pearson's coefficient formula. METHODS: A total of 25 patients aged between 18 and 50 years, clinically diagnosed with epilepsy prior to the start of phenytoin therapy were included based on selection criteria and written informed consents were obtained. Assessment of serum folic acid levels and gingival enlargement was done prior to the start of and after 6 months of phenytoin therapy. RESULTS: The results of the study confirmed a significant association between low serum folate levels with increasing severity as well as an early onset of phenytoin-induced gingival enlargement. CONCLUSIONS: The results of the study suggest a higher incidence of gingival enlargement in phenytoin treated epileptic patients with a positive correlation with falling serum folic acid levels as the duration of the therapy increases.
