Abstract
BACKGROUND AND STUDY AIMS Colonic tuberculosis is generally diagnosed by colonoscopy and targeted biopsy of lesions. However, the diagnostic yield of colonic biopsies is not very good. So far as we are aware, there have been no studies investigating the role of biopsies from endoscopically normal-appearing cecum and terminal ileum in diagnosing colonic or ileal tuberculosis, or both. PATIENTS AND METHODS Patients with a clinical suspicion of colonic tuberculosis, in whom no endoscopic abnormalities were found on colonoscopy or ileoscopy, were included in the study. Multiple biopsies were obtained from the cecum and ileum. RESULTS Fifty patients were studied. Intubation of the terminal ileum was possible in 43 patients (86 %). Histological examination of biopsies obtained from the cecum and terminal ileum showed noncaseating granuloma in two patients. Both of these biopsies were from the terminal ileum. In two other patients, collections of loosely arranged epithelioid cells were observed. This established the diagnosis in these four patients (8 %). In the remaining 46 patients, histology showed nonspecific inflammation in 18 patients (in the cecum in 15 and in the terminal ileum in seven). The other biopsies did not show any abnormalities (33 from the cecum, 34 from the terminal ileum). CONCLUSIONS Histological examination of biopsies from the normal-appearing cecum and terminal ileum is useful in a small but significant number of patients with colonic tuberculosis.

Abstract
AIMS 1. To assess the prevalence of visual impairment in those patients who sustain proximal hip fracture after a simple fall. 2. To test the validity of a simple screening test to identify patients with visual impairment. METHODS Patients on the orthopaedic rehabilitation ward recuperating from proximal hip fracture were recruited. The nurse screener and examining Ophthalmologist independently assessed the patients' distance visual acuity and visual field to confrontation. In addition, the nurse screener assessed for the presence of cataract in the red reflex and the examining Ophthalmologist performed a dilated slit-lamp examination. On completion of the examination, the Ophthalmologist documented the cause(s) of any visual impairment found. RESULTS A total of 89 patients were assessed. In all, 29 patients (33%) could be classified as visually impaired using the United States criteria and 52 patients (58%) had a distance visual acuity of 6/18 or worse in at least one eye. The test reliably identified those patients with visual impairment (sensitivity 94% (+/-5%), specificity 92% (+/-6%)), but was less reliable at identifying those patients with potentially remedial visual impairment (sensitivity 70% (+/-10%), specificity 92% (+/-6%)). CONCLUSION The level of visual impairment in this group of patients is high and screening for visual impairment in the elderly with a history of falls is justified. We have demonstrated that a suitably trained member of the rehabilitation team can identify over 94% of those patients with impaired vision. We believe this simple test should now be incorporated into the assessment of all patients requiring rehabilitation after a proximal hip fracture.

Abstract
The present study was designed to investigate the role of skin sphingosine inhibition in enhancing the transcutaneous permeation of 5-fluorouracil (5-FU), a hydrophilic drug, across rat skin. Ethanol-perturbation significantly reduced the sphingosine content as compared to that in normal skin until 24 h of perturbation (p < 0.05). To maintain the low content of sphingosine for a longer time, beta-chloroalanine (beta-CA), a selective inhibitor of serine palmitoyl transferase, was used for inhibiting the sphingosine synthesis in viable skin. Application of beta-CA (600 microg or 1200 microg/7 cm2) to viable skin perturbed with ethanol significantly reduced the sphingosine content until 48 h as compared to that in perturbed viable skin (p < 0.05). However, the sphingosine content in viable skin perturbed with ethanol and treated with lower doses (200 or 400 microg/7 cm2) of beta-CA, returned significantly close to that in ethanol-perturbed viable skin at 36 h (p < 0.05). Skin sphingosine synthesis inhibition efficacy of 1200 microg beta-CA was insignificantly different to that of 600 microg dose of beta-CA at 36 h or 48 h (p < 0.05). The systemic delivery of percutaneously applied 5-FU across ethanol-perturbed rat skin treated with either 600 microg or 1200 microg beta-CA was significantly greater as compared to that obtained after oral administration or after application of lower percutaneous doses of beta-CA (p < 0.05). Higher Cmax, MRT, AUC and maintenance of effective plasma concentration of 5-FU for 46 h was achieved by a single topical application of a formulation containing 5-FU and 600 microg beta-CA to ethanol-perturbed skin.

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
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.
