Abstract
PURPOSE To report efficacy of photodynamic therapy (PDT) in the treatment of three cases of juxtafoveal circumscribed choroidal haemangioma. METHODS Data on three patients (two primary, and one failed TTT) treated with verteporfin, 6 mg/m2 given as i.v. infusion over 10 min. Diode laser (690 nm) with an intensity of 600 mW/cm2 for 83 s (50 mJ/cm2) was applied 5 min after completion of infusion. Overlapping multiple spots (2500 microm) were applied to cover the entire surface of the tumour. The mean pretreatment tumour size was 7 mm (base) x 2.2 (thickness) mm. Periodic follow-up with ophthalmoscopy, ultrasonography, and angiographic studies was performed. RESULTS All three cases showed complete regression of the tumour with resolution of subretinal fluid, flattening of tumour, and absence of choroidal vasculature on ICG. The visual acuity either improved or remained stable in all three cases. The overlying retinal vessels remained unaffected. There were no ocular or systemic complications. CONCLUSIONS PDT is an effective treatment for management of juxtafoveal circumscribed choroidal haemangioma.

Abstract
Several medical conditions are believed to be associated with an increased risk of cutaneous adverse reactions to anti-epileptic drugs. The aim of this study was to study the frequency and nature of cutaneous reactions in a cohort of patients being treated with phenytoin sodium for seizures, who were divided into those with a solitary cysticercus granuloma (SCG) and those with a condition other than SCG, to determine if the presence of SCG increases the risk of cutaneous adverse reaction to phenytoin. A cohort of 117, consecutively begun on treatment with phenytoin for seizure control, were followed up prospectively for the development of cutaneous reactions. There were 63 patients with SCG upon imaging and 54 patients to whom phenytoin was administered for seizures due to causes other than SCG or multiple neurocysticercosis. Cutaneous reactions were significantly more common (p = 0.02) in patients with SCG (9/63 patients; 14.3%) than in controls (2/54 patients; 3.7%). The spectrum of skin reactions in patients with SCG included benign skin rash (n = 3), anticonvulsant hypersensitivity syndrome (n = 4), Stevens-Johnson syndrome (n = 1), and urticaria (n = 1). Individuals with seizures due to SCG have a high incidence of cutaneous adverse reactions to phenytoin. This fact should be kept in mind when initiating them on treatment with this anti-epileptic drug.

Abstract
The chloroform extract of Croton roxburghii bark (CECR, Euphorbiaceae) and ethyl acetate extract of Zizyphus jujuba bark (EAZJ, Rhamnaceae) were evaluated for anti-steroidogenic activity in the adult female mouse. This study was designed to assess the effects of CECR and EAZJ on ovarian steroidogenisis. Antifertility activity was evaluated by observing the estrus cycle, body weight, wet weight of ovaries, steroidogenic enzymes, and substrates. Blood profiles were estimated to find out the toxic manifestations of the extracts. CECR and EAZJ each arrested the normal estrus cycle of adult female mouse at diestrus stage and reduced the wet weight of ovaries significantly. Cholesterol and ascorbic acid content in ovaries of crude extract-treated mice were significantly elevated. The significant inhibition of delta(5)-3beta-hydroxysteroid dehydrogenase (delta(5)-3beta-HSD) and glucose-6-phosphate dehydrogenase (G-6-PDH), the two key enzymes involved in ovarian steroidogenisis, were also observed in mouse after 18 days of treatment. Hematological profiles, biochemical estimations of whole blood and serum remains unaltered in extract-treated mouse. Normal estrus cycle and ovarian steroidogenisis were restored after withdrawal of treatment with CECR and EAZJ on average 27 and 32 days, respectively. Antifertility activities of crude extracts were found to be reversible.

Abstract
Human polyomavirus type BK (BKV) associated nephritis (BKVAN) has recently emerged as an important cause of renal allograft dysfunction and failure. Early recognition of this entity as a cause of allograft dysfunction is extremely important since misdiagnosis can accelerate graft loss. We report a case of BKVAN that presented with symptoms related to cystitis, and review the risk factors, the diagnostic tools and the approach to treatment of BK virus associated allograft nephropathy.

Abstract
Herpes virus infections remain a major challenge in solid organ transplantation. HHV6 and 7 blood viral load was associated with pathology after renal transplantation. Little is known about the significance of tissue HHV6 and 7 infections. A total of 18 tissue biopsies (13 kidney, three GI and two BAL) from nine pediatric transplant patients (five kidney, two liver, one combined liver and kidney and one bone marrow transplant) were subjected to blood HHV6 IgG and IgM testing. In addition, tissue HHV6 and 7 semi-quantitative PCR analysis with subsequent detection by ELISA and quantitative methods were applied to the same samples. We also studied four native kidney biopsies of children with other kidney disease. The results of the biopsies were correlated with clinical data. Of the transplant patients, 78% were HHV6 IgG positive. Six of nine had a positive IgM on at least one occasion, however, only two of nine transplant patients were symptomatic with a mixed CMV/EBV septic picture of multi-organ failure. Only these two patients had a significant tissue viral load for HHV6. Additionally, a very significant tissue viral load for HHV6 was detected in an immunocompromised patient 3 wk after a roseola-like febrile illness. The HHV6 copies were 31, 88 and 206 per 10 microL of DNA, respectively. In the patient who also had the fourth positive ELISA for HHV6 PCR product, the Multiplex PCR and restriction enzyme assay on its PCR product revealed a significant contribution by HHV7, while the HHV6-B signal was rather weak. Significant tissue HHV6 loads can be found in tissue biopsies from organ recipients with significant illness and also in native kidneys after primary infection. This may explain the high prevalence of HHV6 in transplanted kidneys. Further studies on HHV6 and 7 using molecular techniques should be supported.

Abstract
BACKGROUND In this study, we tested the hypothesis that maternal pneumoperitoneum produces early postnatal behavior deficits in the offspring. METHODS Time-dated pregnant guinea pigs were exposed to 45 min of carbon dioxide (CO2) pneumoperitoneum at a pressure of 7 mmHg. There was no manipulation of the control animals. On postnatal days (PND) 10 and 20, the behavior of their offspring was assessed by monitoring the locomotor activity of each of the pups in a 1 x 1 m chamber demarcated into 100 squares. Locomotor data was log-transformed and expressed as mean values (SD). RESULTS At PND 10, pneumoperitoneum offspring exhibited significantly higher levels of locomotor activity than the offspring of controls (1.81 +/- 0.48 vs 1.33 +/- 0.78). The pneumoperitoneum pups continued to exhibit hyperactive behavior at PND 20 (1.83 +/- 0.72 vs 1.20 +/- 0.72). CONCLUSIONS Maternal pneumoperitoneum produces postnatal hyperactivity in guinea pig offspring, suggesting that there may be long-term consequences associated with the physiologic changes produced in the fetus during CO2 insufflation.

Abstract
The effect of methanolic extract (ME) of Cuscuta reflexa stem Roxb. and Corchorus olitorius Linn. seed on the onset of reproductive maturity and the ovarian steroidogenesis was studied by means of biochemical techniques. ME of Cuscuta reflexa stem and Corchorus olitorius seed treatment causes a remarkable delay in sexual maturation as evidenced by the age at vaginal opening and appearance of first estrus (cornified smear). The same treatment also results in a significant diminution of Delta(5)-3beta-hydroxysteroid dehydrogenase (HSD) and glucose-6-phosphate dehydrogenase (G-6-PD) activity along with a reduction in the weight of ovary, uterus and pituitary. On the basis of above data, it is assumed that the probable cause of delayed maturation in ME of Cuscuta reflexa stem and Corchorus olitorius seed treated mice is due to the suppressed ovarian steroidogenesis.

Abstract
Major histocompatibility complex class I chain-related gene A (MICA) encodes polymorphic, stress-inducible antigens recognized by gammadelta T cells within the intestinal epithelium. MICA microsatellite polymorphism has been implicated to be related to different autoimmune diseases. Ninety-eight patients with type 1 diabetes (median age, 35 years; range, 9-89 years and 51 patients with latent autoimmune diabetes (LADA; median age, 48 years; range, 19-79 years) were compared with 113 healthy control patients (median age, 35 years; range, 19-65 years) to study the importance of MICA-microsatellite polymorphism and HLA-DR-DQ as genetic risk factors for diabetes. The different factors were compared univariately and by logistic regression analysis. In the logistic regression model, heterozygosity for MICA5.0/5.1 was a significant risk factor for LADA (odds ratio [OR] = 12; 95% confidence interval [95%CI], 2.5-59) as well as heterozygosity for HLA-DR3-DQ2/DR4-DQ8 (OR = 15; 95%CI, 2.7-84). None of the MICA polymorphisms were related to type 1 diabetes. Heterozygosity for HLA-DR3-DQ2/DR4-DQ8 was a risk factor for type 1 diabetes (OR = 14; 95%CI, 2.9-66) as well as DR4-DQ8/x (OR = 2.8; 95%CI, 1.4-5.9). HLA-DR15-DQ6 was protective for type 1 diabetes (OR = 0.12; 95%CI, 0.015-0.96). We concluded that both heterozygosity for MICA5.0/5.1 and HLA-DR3-DQ2/DR4-DQ8 are separate risk factors for LADA, but that heterozygosity for HLA-DR3-DQ2/DR4-DQ8 and DR4-DQ8 alone are most important for type 1 diabetes.

Abstract
Type 1 diabetes mellitus (T1DM) is an autoimmune disorder in which genetics and environmental factors play a role. Among the environmental factors, viruses (especially Coxsackie virus B [CBV]), and among genetic markers, human leukocyte antigen (HLA) DRB1*04-DQA1*0301-DQB1*0302 (DR4-DQ8) and DRB1*03-DQA1*0501-DQB1*0201 (DR3-DQ2), and major histocompatibility complex class I chain-related gene-A (MICA) alleles 5 and 5.1 have been reported to be associated with T1DM in Caucasians. Sweden ranks third in the world for T1DM incidence. In Sweden, the Linköping region indicates the highest incidence for T1DM. In this study, we analyzed whether antibodies against CBV are increased in DR3, DR4, MICA5, or MICA5.1 positive patients from Linköping (n = 46) and from Swedish population as a whole (n = 298) between the age of 0 and 15 years old. There was no difference in the frequency of antibodies to CBV in patients compared with controls in Linköping (26% vs 23%) or in all of Sweden (26% vs 21%). However, CBV antibodies were increased in DR3, DR3-DR4 (heterozygous), DR3-MICA5.1, and DR3-DR4-MICA5.1 positive compared with DR3, DR3-DR4, DR3-MICA5.1, and DR3-DR4-MICA5.1 negative patients in Linköping (p < 0.05 for all), but not in Swedish population as a whole. Thus, our study suggests that in addition to DR3, MICA5.1 has an influence on the immune response to CBV infection in patients from Linköping.

Abstract
OBJECTIVE To study the prevalence and pattern of use of complementary and alternative medicine (CAM) in patients with essential hypertension. METHOD 521 consecutive patients visiting the Hypertension Clinic at the Postgraduate Institute of Medical Education and Research, Chandigarh, India, over a 6-month period were interviewed. Information was gathered on the patients' demographics, type(s) of CAM used, sequence of seeking CAM and conventional medicine, sources of recommendation, reasons for opting for CAM and areas of satisfaction and dissatisfaction associated with the use of CAM. Patients were also asked if they had informed their doctor about CAM use. RESULTS It was observed that 63.9% of patients overall used CAM. Ayurveda was the most commonly used CAM (56.7%), followed by herbal medicines (14.4%). The most commonly cited reason by patients for using CAM was fear of adverse drug reactions of conventional medicines (59.0%). However, more than half of the patients eventually became dissatisfied using CAM. Only 5.4% of CAM users had informed their medical doctors about the use of CAM. CONCLUSION A significant proportion of patients receiving conventional treatment for hypertension also use CAM therapies. A better understanding of the pattern of CAM use amongst these patients will help dispel prevalent misconceptions concerning CAM and, at the same time, assist conventional practitioners to critically evaluate possible gaps or omissions in their own prescribing habits.

Abstract
BACKGROUND Prompt treatment of patients presenting with acute myocardial infarction decreases the incidence of death from early arrhythmia, and maximizes the potential benefit of thrombolytic therapy. Prehospital delay has been identified as a major obstacle to the widespread use of thrombolytic therapy. The aim of the present study was to examine the extent of, and factors associated with, delay in seeking medical care (usually thrombolytic therapy) in patients with acute myocardial infarction. METHODS AND RESULTS The study was conducted in patients visiting the medical emergency unit of the Nehru Hospital, Post Graduate Institute of Medical Education and Research, Chandigarh. A total of 104 patients diagnosed with acute myocardial infarction were interviewed using a pre-designed proforma. Pain-to-door, and door-to-drug times, were the main outcome measures. The corrected mean (SEM) and median (range) pain-to-door times were 8.5 (0.8) hours and 5.2 (0.5-24) hours, respectively. Out of 104 patients, 38 did not receive thrombolytic therapy. In those who did not receive thrombolytic therapy, prior therapy at local health centers, lack of knowledge of symptoms, and transportation problems were the main reasons for hospital delay. The mean (SEM) and median (range) of door-to-drug times were 1.2 (0.1) hours and 1 (0.2-3.5) hours, respectively.

Abstract
Methanolic extract (ME) of both C. reflexa stem and C. olitorius seed arrested the normal oestrus cycle of adult female mouse and significantly decreased the weight of ovaries and uterus. The cholesterol and ascorbic acid contents in ovaries were significantly increased in the treated mice. Two key enzymes, delta5-3beta-hydroxysteroid dehydrogenase and glucose-6-phosphate dehydrogenase, were decreased significantly in ME of both C. reflexa stem and C. olitorius seed after 17 days of treatment. High level of substrates and low level of enzymes indicate the inhibition of steroidogenesis in treated mice and may be due to the presence of flavonoids.

Abstract
The dystrophin gene was analyzed in 8 Duchenne muscular dystrophy (DMD) and 10 Becker muscular dystrophy (BMD) unrelated families (22 subjects: 18 index cases and 4 sibs) for the presence of deletions by multiplex polymerase chain reaction (mPCR; 27 exons) and Southern hybridization using 8 cDMD probes. Deletions were identified in 5 DMD and 7 BMD patients (6 index cases and 1 sib). The concordance between the clinical phenotype and "reading frame hypothesis" was observed in 11/12 patients (92%). The female relatives of DMD/BMD patients with identifiable deletions were examined by quantitative mPCR. Carriers were identified in 7 families. We also describe a variation in the HindIII pattern with cDNA probe 8 and 11-14. Molecular characterization of the dystrophin gene in this study has been helpful in advising the patients concerning the inheritance of the condition, and carrier diagnosis of female relatives, and should also prove useful for prenatal diagnosis.

Abstract
Evidence-based medicine (EBM) is a concept that has grown to dominate the medical literature over the last decade. EBM has provoked a variety of criticisms, scientific, philosophical and sociological. However, while its basic conclusion--that we should practise EBM--is ethical, there has been limited ethical analysis of EBM. This paper aims to provide an analysis of EBM from an ethical perspective and identify some of EBM's potential ethical implications. Following a description of what constitutes EBM, this paper will identify and assess some of the basic values and epistemological assumptions of EBM that provide support for the moral duty to practise EBM. It will then examine potential ethical implications that could arise from practising EBM, given the challenges that have been made of EBM's assumptions and claims to authority. This paper will conclude by arguing that practitioners could strengthen the ethics of EBM by embracing a broader definition of evidence and including ethical criteria in the critical appraisal of research studies.

Abstract
Major histocompatibility complex (MHC) class I chain related gene-A (MIC-A) is associated with type 1 diabetes mellitus (T1DM) in other populations. We tested the association of MIC-A gene polymorphism with T1DM in Swedish Caucasians; if it has an age-dependent association; and if the association has an effect on gender. We studied 635 T1DM patients and 503 matched controls in the age group of 0-35 years old. MIC-A5 was significantly increased in T1DM compared with controls (odds ratio [OR] =1.81, p(c) < 0.0005). Logistic regression analysis revealed MIC-A5 association was independent of HLA. MIC-A5 with DR4-DQ8 or MIC-A5 with DR3-DQ2 gave higher OR than the OR obtained with either of them alone (OR = 1.81, 7.1, and 3.6, respectively). MIC-A5 was positively (OR = 2.48, p(c) < 0.0005) and MIC-A6 negatively associated (OR = 0.61, p(c) = 0.035) with the disease in < or = 20 years of age. The negative association of MIC-A6 in young onset was confirmed by logistic regression analysis. MIC-A5 was associated with the disease in males (OR = 2.05, p(c) = 0.0005). MIC-A6 conferred protection (OR = 0.098, p(c) = 0.032) in females heterozygous for DR3/DR4. In conclusion, MIC-A5 is associated with T1DM; the association was higher in individuals < or = 20 years old; and negative association of MIC-A6 was stronger in younger onset patients than in older onset patients.

Abstract
In order to define the prevalence of haemostatic defects in women presenting with menorrhagia in our region, the coagulation data on women bleeders investigated in the Department of Haematology, AIIMS, were analysed. A total of 337 of the 2200 menorrhagic women investigated were characterized to have an inherited bleeding disorder; 221 of these 337 women presented with menorrhagia alone while 116 also had other associated bleeding manifestations as prolonged bleeding from injury site, ecchymotic patches in the skin, epistaxis, haematomas, haemarthroses and major bleeds like intracerebral bleeding. The tests performed included bleeding time (BT), platelet count, prothrombin time (PT), prothrombin consumption index (PCI), activated partial thromboplastin time (APTT), PF3 release with adenosine diphosphate (ADP) at 0 and 20 min, total PF3 assay and platelet Aggregation studies with collagen, ADP, adrenaline, arachidonic acid and ristocetin. Coagulation factor assays, von Willebrand antigen estimation, ristocetin cofactor assay and electron microscopy were performed wherever necessary. Inherited platelet dysfunction was seen in 283 (83.9%) of the patients. Amongst these, isolated PF3 availability defect was seen in 163 (48.4%) cases. Glanzman's thrombasthenia was seen in 30 (8.9%) patients, Storage pool disease in eight (2.4%) patients, arachidonic acid pathway defect in five (1.5%) patients and Bernard-Soulier Syndrome in six (1.8%) patients. In 71 (21.1%) patients, the platelet function defect could not be classified into any specific subtypes. Inherited defects of coagulation were observed in 54 (16%) of the cases. Amongst these, von Willebrand disease (vWD) was the most frequent being seen in 40 (11.9%) of the cases. Factor XIII deficiency was seen in one (0.3%), factor X deficiency in four (1.2%), factor VII deficiency in one (0.3%) and factor XII deficiency in one (0.3%) of the patients. It is concluded that although hereditary platelet function defects constitute a large majority of women bleeders in India but among the coagulation defects, vWD is the commonest as reported from the caucasian population. It is thus suggested that in women presenting with menorrhagia, screening tests for haemostasis especially for vWD and inherited platelet function defects must be performed.

Abstract
The methanol extract of the whole plant of Vernonia cinerea Less. was evaluated for its anti-inflammatory activity in acute (carrageenin, histamine and serotonin induced rat paw edema) and a chronic model (cotton pouch induced granuloma). The methanol extract (250 and 500 mg/kg(-1) p.o.) exhibited significant activity (p < 0.001) against all phlogistic agents used in a dose dependant manner. In the chronic model (cotton pouch granuloma method) the methanol extract exhibited significant anti-inflammatory activity. All these effects were compared with standard drug phenylbutazone (100 mg/kg(-1) p.o.).
