RESUMO

AIM: To report on the prevalence, defect characteristics, and distribution of hypomineralised second primary molars (HSPM) in Gautam Budh Nagar, Uttar Pradesh, India and to report on possible association, if any, between HSPM and molar-incisor-hypomineralisation (MIH). METHODS: A cross-sectional survey included a random sample of 978, 6-8-year-old school children. EAPD diagnostic criteria for scoring MIH defects on first permanent molars (FPM) were adapted and used to score hypomineralisation defects in both FPM and second primary molars (SPM) by a single calibrated examiner. Comparative statistics for HSPM versus hypomineralised FPM were computed using a Chi square test. An odds ratio (OR) at 95 % confidence interval (CI) was used to test and any association between HSPM and MIH. RESULTS: An overall prevalence of 5.6 % (55/978) was reported for HSPM in the study population. Prevalence of MIH as hypomineralised FPM was 7.4 % (72/978). Concomitant presence of HSPM and MIH was observed in 32.73 % (18/55) of affected subjects. The presence of HSPM had significantly higher odds ratio for development of MIH (OR 7.82; 95 % CI = 4.18-14.65; p < 0.001). A greater severity of defects was observed in HSPM compared with affected FPM as greater number of affected surfaces presented with post-eruptive breakdown (PEB) in former compared to latter (p < 0.001). CONCLUSION: The prevalence of HSPM in 6-8-year-old Indian children was 5.6 %. The severity of hypomineralisation was milder in FPM compared to SPM. The presence of HSPM was reported to have significantly higher odds for development of MIH in future.

RESUMO

Chest wall tuberculosis is a rare entity especially in an immunocompetent patient. Infection may result from direct inoculation of the organisms or hematogenous spread from some underlying pathology. Infected lymph nodes may also transfer the bacilli through lymphatic route. Chest wall tuberculosis may resemble a pyogenic abscess or tumour and entertaining the possibility of tubercular etiology remains a clinical challenge unless there are compelling reasons of suspicion. In tuberculosis endemic countries like India, all the abscesses indolent to routine treatment need investigation to rule out mycobacterial causes. We present here a case of chest wall tuberculosis where infection was localized to skin only and, in the absence of any evidence of specific site, it appears to be a case of primary involvement.

RESUMO

BACKGROUND: Liver abscess is fairly common in developing countries and its incidence is ever-rising. Though amoebic and pyogenic liver abscesses form majority of cases in our country, tubercular liver abscess (TLA) should also be considered as differential diagnosis. AIMS: To study the clinical and imaging profile of tubercular liver abscess while establishing its increased incidence. METHODS: A prospective observational study was carried out on 72 indoor cases of liver abscess, presenting to Department of Medicine, from November 2011 to February 2013. All cases were subjected to abscess tap and tapped abscess was sent for microbiological examination. RESULTS: Though amoebic liver abscess was most common type diagnosed, five cases came out to be tubercular (AFB positive). Mean age of TLA patients was 28.4 years (all males). All cases were sub-acute in presentation. Splenomegaly and ascites were noted in 60% and 40% cases respectively. ESR was raised in 80% cases with mean value of 52.8 mm at first hour. Haemoglobin was low in 80% cases. Serum Alkaline phosphatise (ALP) was raised in all cases, mean value being 1034.4 U/L. On ultrasonography, all abscesses were < 5 centimetres in size, most commonly involving seventh segment. They were multiple in numbers in 60% cases. All cases responded well to anti-tubercular treatment. CONCLUSIONS: Tubercular liver abscess has increased in incidence, and in majority of cases in our study, they were incidentally found with no associated foci of infection in lung or gastrointestinal tract. So, keeping high index of suspicion, TLA should be considered in all patients with subacute presentation and associated anaemia, splenomegaly or ascites. Also, TLA is associated with raised ESR and comparatively higher levels of ALP in serum. They are more commonly multiple in number on ultrasonography.

RESUMO

BACKGROUND: Pulmonary infections remain a leading cause of morbidity and mortality and one of the most frequent causes of hospital admission in HIV infected people worldwide. HRCT may be useful in the evaluation of patients with suspected pulmonary disease. The aim of given study was to determine the High Resolution Computed Tomography spectrum of lung parenchymal and interstitial imaging findings in HIV infected patients presented with chest symptoms. MATERIALS AND METHODS: This study was conducted in a tertiary health care centre, New Delhi, India. The study consisted of 45 patients. A thorough clinical history of all the HIV positive patients presenting with suspicion of pulmonary disease was taken. General physical and respiratory system examination of all patients was done. HRCT scans of the chest were done in all the cases taken in the study. RESULTS: Maximum number of patients was in age group 31-40 years (24 cases). Out of 45 patients included in our study, 32 (71%) were male and 13 (29%) were female. In our series of 45 patients, 62.2% of patients were diagnosed as having pulmonary tuberculosis, followed by bacterial infection in 20% cases and Pneumocystis jiroveci pneumonia (PJP) in 8.9% patients, while 8.9% of the study did not reveal any significant abnormality. Maximum number (22/28) of patients with pulmonary tuberculosis were indentified to have nodular opacities. The most common HRCT finding in bacterial infection was lobar consolidation. The most common HRCT finding in patients with PCP was diffuse ground glass opacities in mosaic pattern of distribution. CONCLUSION: HRCT is a highly sensitive tool for detecting lung parenchymal and interstitial lesions and allows better characterization of the lesions. HRCT findings should always be correlated with clinical findings, CD4 counts and other available investigations before arriving at a diagnosis or differential diagnosis.

RESUMO

To determine the various factors influencing glycemic response to pioglitazone monotherapy in newly diagnosed Asian Indian T2DM patients. Thirty T2DM patients (age 53.23 +/- 8.067 yrs, M: F ratio 14:16) were treated with pioglitazone for at least 14 weeks. Relationship between its glucose lowering effect and following patient parameters was studied: BMI, W:H ratio, HOMA-R, HOMA-beta and Pro12Ala polymorph of PPAR-gamma gene. Glycemic targets could be achieved in 20 (66.67%) subjects. All the parameters were comparable among responders and non-responders at the start of therapy. All the participants were homozygous for Pro allele of Pro12Ala polymorph of PPAR-gamma gene. There was a significant positive association between glycemic response to pioglitazone and W: H ratio (beta = 0.426, P = 0.034) and HOMA-R (beta = 0.563, P = 0.008). Primary pioglitazone failure cannot be explained on the basis of body fat and its distribution, insulin resistance and secretory function and Pro12Ala polymorph of PPAR-gamma gene. Among responders central obesity and high insulin resistance were associated with better glycemic response.

RESUMO

Present study was undertaken with a view to assess the utility of AgNOR counts in differentiating cervical lesions. One hundred cases of cervical lesions including normal, chronic cervicitis, CIN (I, II, III) and carcinoma were taken up for study during the period December 1995 to November 1996. Three micron thick sections of paraffin were subjected to AgNOR staining as described by Crocker and Smith with a little modification of 0.01% safranin counterstain. Statistical counts of AgNORs were done. The mean AgNOR counts in cervical epithelium showed a progressive and statistically significant increase from normal to chronic cervicitis to CIN, I, II and III (P<0.001). Scores in carcinoma also exceeded that of CIN (P<0.05). This can prove to be a useful adjunct to routine histopathology to evaluate cervical lesions.

RESUMO

Silver nucleolar organizer regions (AgNORs) were studied in one hundred specimens of endobronchial brushings. Bronchial biopsies were also obtained from these one hundred cases and subjected to AgNOR staining. These included twenty histologically normal cases, ten cases of inflammatory pathology and seventy cases of pulmonary neoplasms. Fixed cytologic smears and three micron thick sections of paraffin embedded tissue were subjected to AgNOR staining. The mean AgNOR counts in bronchial tissue showed a progressive and statistically significant increase from normal, through inflammatory to neoplastic lesions in both cytologic smears and histopathologic specimens. The AgNOR technique is simple, inexpensive and a useful adjunct to routine histopathology, to evaluate pulmonary lesions. The counts, however, cannot be standardized for a particular lesion as there are inter-laboratory variations.

RESUMO

The generation of discriminative, monospecific anti-HLA antibodies used to be a difficult endeavor. Phage display technology, using single-chain antibody fragments (scFv) offers a powerful alternative obtaining target-specific, genetically stable reagents. Most of scFv obtained to date have been enriched by panning phage libraries to solid-phase coupled antigens. In the present study, HLA-C-specific scFv were isolated using a synthetic phage library in combination with a Cw*0602 overexpressing cell line. ScFv from this procedure precipitated HLA-Cw*0602 heavy chains from whole cell lysates. Flow cytometry analysis revealed that scFv stained HLA-Cw*0602-positive cells, but not cells expressing HLA alleles Cw*0302, Cw*0802, A*0201, B*2705, or Gm1*01011, indicating the specificity of scFv. Similarly they showed an ability to discriminate Cw*0602-positive from Cw*0602-negative peripheral blood lymphocytes (PBL). The results of our study demonstrate the feasibility to genetically engineer single-chain HLA-class I-specific antibodies, by phage display technology. This approach might be a valuable tool to develop a broad range of novel monospecific antibodies against HLA-class I specificities.

RESUMO

Silver nucleolar organizer region (AgNOR) staining was employed in one hundred specimens of endometrium. These included fifteen normal controls (Proliferative + Secretory endometrium) and eighty five lesions. Endometrial lesions comprised of endometritis (15), endometrial hyperplasia (25) and endometrial carcinoma (45). Three micron thick sections of paraffin embedded tissue were subjected to AgNOR staining as described by Crocker and Smith with a little modification of 0.01% safranin counterstain--The mean AgNOR scores were found to increase steadily from normal to endometritis to endometrial hyperplasia and carcinoma--The observations revealed statistically significant differences in values between atypical hyperplasia and carcinoma also. AgNOR staining and scoring is simple, inexpensive and a useful adjunct to routine histopathology to evaluate endometrial lesions especially to differentiate borderline lesions. Though scores cannot be standardized and fixed for a particular lesion as there are intralaboratory variations.

RESUMO

Topical multiple lamellar vesicular liposomes were formulated by using the method reported by Bangham (1968). The liposomes, composed of different lipid and charge-bearing components such as stearylamine or dicetylphosphate, were characterized for average size, size distribution, charge lamellae and drug loading. The negatively charged liposomes showed high drug loading and were incorporated in different topical vehicles, i.e. gels and ointment. These were evaluated for in vitro drug skin permeation profile. The selected formulations were evaluated for in vivo performance using the pinprick method. The results revealed localized and prolonged activity of local anaesthetic contained in liposomes when compared with equivalent conventional topical application.

RESUMO

The study goals were to document the incidence of elevated blood pressure (BP) values in public high school students in Tulsa, Oklahoma; to determine whether age and sex are risk factors; and to encourage adolescents with abnormal screening BP values to seek medical care. Over a 2-year period, 5537 adolescents aged 14 to 19 years were evaluated by a mass screening method. Blood pressure was measured once between 8:30 and 9:30 AM, with the students seated. Korotkoff phases 1 and 5 were recorded as systolic and diastolic BP. According to the criteria of the Second Task Force on Hypertension in Children and Adolescents, 334 students had elevated BP values (either systolic, diastolic, or both) (an incidence of 6%). Boys had an incidence of elevated systolic BP of 5.8%, while girls had a 2.8% incidence, a difference that might have been expected because of the generally higher incidence among men in the adult population. The incidence of elevated diastolic BP was 2.8% in boys and 2.1% in girls. Statistically significant differences between boys and girls mean systolic and diastolic elevations were found, but were not considered clinically significant. An instructional mailing was done in an effort to stimulate follow-up medical care for those with abnormal findings, but its effect was not measured.
