RESUMO

Background : The healthcare delivery system is an important indicator of the quality of life in a society. The advent of the Corona Virus pandemic led to an unfortunate and unforeseen disruption in the healthcare services Globally. The older persons were impacted on multiple counts including limitations in healthcare service availability, access and social marginalization. As we gain more insight into the full impact of the Pandemic on the health quality indicators and look to resume Medical service delivery in Postpandemic times, it’s important to ensure that the older population is not neglected. Discussions : Small transitions in the delivery models but larger modifications in the mind-set may be needed to provide continued, effective and seamless healthcare services to the older Indian population. Planned interventions at each level of the system can ensure a smooth transition into the modified systems. Integration of modern telecommunication technology into the medical practice and extensive research in the area can make telemedicine a more accessible and acceptable option to the elderly patients with chronic ailments. The full extent of the impact of the Pandemic on healthcare will be revealed in the coming times requiring constant adaptation of each element of the system to cope with it.

RESUMO

Background & objectives: Multidrug-resistant tuberculosis (MDR-TB) has emerged as a significant global health concern. The most important risk factor for the development of MDR-TB is previous anti-tuberculosis therapy. Category II pulmonary TB includes those patients who had failed previous TB treatment, relapsed after treatment, or defaulted during previous treatment. We carried out this study to ascertain the prevalence of MDR-TB among category II pulmonary TB patients. Methods: This was a cross-sectional, descriptive study involving category II pulmonary TB patients diagnosed between 2005 and 2008. All sputum-positive category II TB cases were subjected to mycobacterial culture and drug-susceptibility testing (DST). MDR-TB was defined as TB caused by bacilli showing resistance to at least isoniazid and rifampicin. Results: A total of 196 cases of sputum-positive category II pulmonary tuberculosis patients were included. Of these, 40 patients (20.4%) had MDR-TB. The mean age of MDR-TB patients was 33.25 ± 12.04 yr; 9 patients (22.5%) were female. Thirty six patients showed resistance to rifampicin and isoniazid; while 4 patients showed resistance to rifampicin, isoniazid and streptomycin. The prevalence of MDR-TB among category-II pulmonary tuberculosis patients was 20.4 per cent. Interpretation & conclusions : The prevalence of MDR-TB in category II TB patients was significant. However, nation-wide and State-wide representative data on prevalence of MDR-TB are lacking. We stress the importance of continuous monitoring of drug resistance trends, in order to assess the efficacy of current interventions and their impact on the TB epidemic.

RESUMO

Background & objectives: The prevalence of multidrug-resistant tuberculosis (MDR-TB) is increasing throughout the world. Although previous treatment for TB is the most important risk factor for development of MDR-TB, treatment-naïve patients are also at risk due to either spontaneous mutations or transmission of drug-resistant strains. We sought to ascertain the prevalence of MDR-TB among new cases of sputum-positive pulmonary TB. Methods: This was a prospective, observational study involving newly diagnosed cases of sputum-positive pulmonary tuberculosis diagnosed between 2008 and 2009 carried out in New Delhi, India. All sputum-positive TB cases were subjected to mycobacterial culture and first-line drug-susceptibility testing (DST). MDR-TB was defined as TB caused by bacilli showing resistance to at least isoniazid and rifampicin. Results: A total of 218 cases of sputum-positive pulmonary tuberculosis were enrolled between 2008 and 2009. Of these, 41 cases had negative mycobacterial cultures and DST was carried out in 177 cases. The mean age of the patients was 27.8 ± 10.2 yr; 59 patients (27%) were female. All patients tested negative for HIV infection. Out of 177 cases, two cases of MDR-TB were detected. Thus, the prevalence of MDR-TB among newly diagnosed pulmonary tuberculosis patients was 1.1 per cent. Interpretation & conclusions: MDR-TB prevalence is low among new cases of sputum-positive pulmonary TB treated at primary care level in Delhi. Nation-wide and State-wide representative data on prevalence of MDR-TB are lacking. Efforts should be directed towards continued surveillance for MDR-TB among newly diagnosed TB cases.

RESUMO

Background: The product of Wilms' tumor suppressor gene (WT1), a nuclear transcription factor, regulates the expression of the insulin-like growth factor (IGF) and transforming growth factor (TGF) systems, both of which are implicated in breast tumorigenesis and are known to facilitate angiogenesis. In the present study, WT1 allelic integrity was examined by Loss of Heterozygosity (LOH) studies in infiltrating breast carcinoma (n=60), ductal carcinoma in situ (DCIS) (n=10) and benign breast disease (n=5) patients, to determine its possible association with tumor progression. Methods: LOH at the WT1 locus (11p13) as determined by PCR-RFLP for Hinf1 restriction site and was subsequently examined for its association with intratumoral expression of various growth factors i.e. TGF-β1, IGF-II, IGF-1R and angiogenesis (VEGF and Intratumoral micro-vessel density) in breast carcinoma. Results: Six of 22 (27.2%) genetically heterozygous of infiltrating breast carcinoma and 1 of 4 DCIS cases showed loss of one allele at WT1 locus. Histologically, the tumors with LOH at WT1 were Intraductal carcinoma (IDC) and were of grade II and III. There was no correlation in the appearance of LOH at WT1 locus with age, tumor stage, menopausal status, chemotherapy status and lymph node metastasis. The expression of factor IGF-II and its receptor, IGF-1R was significantly higher in carcinoma having LOH at WT1 locus. A positive correlation was observed between the TGF-β1, VEGF expression and IMD scores in infiltrating carcinoma. Conclusions: The current study indicates that the high frequency of loss of allelic integrity at Wilms' tumor suppressor gene-1 locus in high-graded breast tumors is associated with aggressiveness of the tumor.

RESUMO

Leprosy in a preschool child appearing at the age of four years is reported due to its rarity, particularly at a time when we are hoping for its elimination. A 5-year-old female child presented with an erythematous rash over-her right buttock for last one year. Histopathological examination from the patch revealed it to be a case of indeterminate leprosy. The child responded favourably with antileprosy treatment.

RESUMO

INTRODUCTION: Cervical cancer is the commonest cancer among Indian women. High-risk human papillomavirus (HPV) detection holds the potential to be used as a tool to identify women, at risk for subsequent development of cervical cancer. There is a pressing need for identifying prevalence of asymptomatic cervical HPV infection in the local population. OBJECTIVE: To determine the prevalence of high-risk HPV DNA in women with benign cervical cytology. MATERIALS AND METHODS: Women visiting the gynecology outpatient with varied complaints were subjected to Pap smear. Four hundred and seventy two samples were subjected to polymerase chain reaction, using consensus primers for low and high-risk HPV (types 6, 11, 16, 18, 31 and 33). The samples that were positive for HPV DNA were subsequently assessed for high-risk consensus primers, types 16, 18, 31 and 33 as well as for HPV type 16 and 18. RESULTS: One hundred and seventy four (36.8%) women tested positive for HPV DNA. Thirty nine (8.2%) of the entire cohort tested positive for high-risk HPV. Fifteen samples were positive for type 16, 22 for type 18 and two for both types 16 and 18. A statistically higher prevalence of high-risk HPV was observed in poorly educated and rural groups. No association of HPV prevalence was noted with age, parity and age at marriage. CONCLUSION: The study generates epidemiological data of prevalence of sub-clinical HPV in the women visiting a tertiary care institute as well as peripheral health centres. The data generated will be useful for laying guidelines for mass screening of HPV, treatment and prophylaxis in the local population.

RESUMO

Screening of drug-resistant variants is very important for the effective clinical management of HIV-infected patients and development of new strategies. The present study was aimed to detect codon-184 mutations in the pol-gene of HIV leading to resistance to lamivudine (3-TC) by nested cum ARMS-PCR approach in 10 treated and 9 treatment naive patients. For correlation the whole blood CD4/CD8 cell counts and the soluble TNFRII levels in plasma were also determined. Of the 19 patients tested, mutant variants were observed in 2 patients (Met Val in one and Met Val & lle in second) both being treated with 3-TC. No mutations were detected in the treatment-naive patients. The results confirmed that, drug resistant variants of codon-184 emerge rapidly in patients receiving 3-TC containing regimens including our population, which is mainly infected with subtypeC of the virus that could be detected along with wild viral population using sensitive approaches such as ARMS-PCR.

RESUMO

Tumors of the central nervous system account for approximately 9% of all primary neoplasm in humans, while tumors of covering elements, the meninges, account for 13-19% and constitute the second largest group of brain tumors. These are known to exhibit a variety of chromosomal abnormalities besides change in the expression level of certain oncogenes. Among oncogenes, bcl2, an anti-apoptotic factor and ROS1 that encodes a protein with a structure similar to the epidermal growth factor (EGF) and insulin receptor and has a tyrosine kinase activity, have been shown to be associated with many malignant tumors. In the present study we have analysed the expression of bcl2 using immuno-histochemistry and ROS1 expression by reverse-transcription coupled with polymerase chain reaction (RT-PCR) of the transcript using primers specific for the intra-cellular domain and then tried to correlate the findings with the subtype of the meningioma defined on the basis of histology. Out of the six bcl2 positive cases in our study, there were three transitional tumors, two fibroblastic and one recurrent meningioma subtype. bcl2 seemed to be more consistently expressed in the cytoplasm of spindle cell component of meningiomas. Thirteen meningiothelial meningiomas did not show any staining for bcl2. ROS1 gene expression could be detected in 4 tumors all of those were Grade-I meningothelial meningiomas. One of the malignant meningioma included in the study was clearly negative for bcl2 as well as ROS1. Thus bcl2 and ROS1 oncogene expression in meningiomas are not concurrent and neither can be ascribed to any histologic subtype or grade of tumor.

RESUMO

Phytotherapies have offered alternative sources of therapy for migraine and gained much importance in prophylactic treatment. Sapindus trifoliatus is a medium-sized deciduous tree growing wild in south India that belongs to the family Sapindaceae. The pericarp is reported for various medicinal properties. A thick aqueous solution of the pericarp is used for the treatment of hemicrania, hysteria or epilepsy in folklore medicine. We have investigated the antihyperalgesic effects of the lyophilized aqueous extract of S. trifoliatus in animal models predictive of experimental migraine models using morphine withdrawal-induced hyperalgesia on the hot-plate test and on 0.3 percent acetic acid-induced abdominal constrictions in adult male Swiss albino mice. The extract significantly (N = 10, P < 0.05) increased the licking latency in the hot-plate test when administered ip at 10 mg/kg (6.70 ± 0.39 s in saline control vs 18.76 ± 0.96 s in S. trifoliatus-treated animals) and significantly (N = 10, P < 0.001) reduced the abdominal constrictions when administered ip at 2 and 10 mg/kg (40.20 ± 1.36 in saline control vs 30.20 ± 1.33 and 23.00 ± 0.98 for 2 and 10 mg/kg, ip, respectively, in S. trifoliatus-treated animals). Furthermore, when administered ip at 20 and 100 mg/kg, the extract significantly (N = 10, P < 0.05) inhibited the apomorphine-induced climbing behavior in mice (climbing duration 15.75 ± 5.0 min for saline control vs 11.4 ± 1.28 and 3.9 ± 1.71 min for 20 and 100 mg/kg, respectively, in S. trifoliatus-treated animals). In receptor radioligand-binding studies, the extract exhibited affinity towards D2 receptors. The findings suggest that dopamine D2 antagonism could be the mechanism involved in the antihyperalgesic activity of the aqueous extract of S. trifoliatus.

RESUMO

Staphylococcus aureus is a major pathogen for pyoderma in India. Phage pattern of bacteria gives valuable information in epidemiological studies of infection. Two hundred and two strains of Staphylococcus aureus isolated from pyoderma cases at Gorakhpur, were phage grouped and phage typed. It was found that 43.1 percent strains were not typable. Most common group was mixed phage group (23.8 percent) followed by phage group III (12.4 percent). Predominant phage types in mixed phage group was 84/81/85 and in phage group III was 84/85.

RESUMO

One hundred and three children with seizure disorder were studied. Plain radiograph skull was normal in all the cases. CT scan skull done in 34 patients, showed abnormalities in 24 cases. More than 80% children in partial seizures group had treatable lesions on CT scans, mainly CNS tuberculoma. The need for omitting plain radiograph skull as a routine investigation for epilepsy cases is emphasized.
