Abstract
Impression cytology refers to the application of a cellulose acetate filter to the ocular surface to remove the superficial layers of the ocular surface epithelium. These cells can then be subjected to histological, immunohistological, or molecular analysis. Proper technique is essential as the number of cells sampled can vary considerably. Generally two to three layers of cells are removed in one application but deeper cells can be accessed by repeat application over the same site. Applications for impression cytology include diagnosing a wide range of ocular surface disorders, documenting sequential changes in the conjunctival and corneal surface over time, staging conjunctival squamous metaplasia, and monitoring effects of treatment. It is also a useful investigational tool for analysing ocular surface disease with immunostaining and DNA analysis. It is non-invasive, relatively easy to perform, and yields reliable information about the area sampled with minimal discomfort to the patient. Major ophthalmic centres should develop and introduce this technique into routine clinical practice. This is best achieved with a team approach including the ophthalmologist, pathologist, microbiologist, and the immunologist.

Abstract
BACKGROUND Oral cancer surgery with reconstruction is a complex operative procedure with morbidities such as respiratory complications and post-operative pain. These morbidities may be reduced with appropriate operative and post-operative pain management. Epidural analgesia provides better pain control than intravenous opioids after major thoraco-abdominal surgical procedures. We planned to undertake a prospective study to compare the efficacy and side-effects of epidural morphine analgesia vs. intravenous morphine in patients undergoing oral cancer surgery with pectoralis major myocutaneous flap reconstruction. METHODS Sixty patients undergoing a major surgical procedure for oral cancer with pectoralis major myocutaneous flap reconstruction were prospectively randomized to receive either epidural morphine or intravenous morphine in the post-operative period. The intensity of pain was assessed daily using a 100-mm visual analogue scale. The post-operative side-effects, time to ambulation, time to tolerate first nasogastric feed, total length of hospital stay and global satisfaction score were recorded. RESULTS The epidural morphine group had statistically significant lower pain scores at the three evaluation times through the post-operative 48 h (P < 0.05). However, the mean visual analogue scores were always below 35 in the intravenous morphine group. Patients in the epidural morphine group ambulated and accepted nasogastric feed significantly earlier than those in the intravenous morphine group. The incidence of nausea/vomiting or pruritus, the length of hospital stay and the global satisfaction score were not statistically different between the groups. CONCLUSION This study illustrates that epidural morphine offers better pain control than intravenous morphine after oral cancer surgery with pectoralis major myocutaneous flap reconstruction. Nevertheless, both methods appear to provide very good pain relief, and perhaps the extra risks inherent to epidural catheter insertion are not outweighed by the benefits in this type of surgery.

Abstract
The natural polphenol, curcumin, retards the growth of intestinal adenomas in the Apc(Min+) mouse model of human familial adenomatous polyposis. In other preclinical models, curcumin downregulates the transcription of the enzyme cyclooxygenase-2 (COX-2) and decreases levels of two oxidative DNA adducts, the pyrimidopurinone adduct of deoxyguanosine (M1dG) and 8-oxo-7,8-dihydro-2'-deoxyguanosine (8-oxo-dG). We have studied COX-2 protein expression and oxidative DNA adduct levels in intestinal adenoma tissue from Apc(Min+) mice to try and differentiate between curcumin's direct pharmacodynamic effects and indirect effects via its inhibition of adenoma growth. Mice received dietary curcumin (0.2%) for 4 or 14 weeks. COX-2 protein, M1dG and 8-oxo-dG levels were measured by Western blot, immunochemical assay and liquid chromatography-mass spectrometry, respectively. In control Apc(Min+) mice, the levels of all three indices measured in adenoma tissue were significantly higher than levels in normal mucosa. Lifetime administration of curcumin reduced COX-2 expression by 66% (P = 0.01), 8-oxo-dG levels by 24% (P < 0.05) and M1dG levels by 39% (P < 0.005). Short-term feeding did not affect total adenoma number or COX-2 expression, but decreased M1dG levels by 43% (P < 0.01). COX-2 protein levels related to adenoma size. These results demonstrate the utility of measuring these oxidative DNA adduct levels to show direct antioxidant effects of dietary curcumin. The effects of long-term dietary curcumin on COX-2 protein levels appear to reflect retardation of adenoma development.

Abstract
Ulcers with maculo-papular rash are an unusual presenting feature of leprosy. They occur as result of neuropathy, type-2 lepra reaction or Lucio's phenomenon. The hall mark of type-2 reaction is erythema nodosum. Very rarely it manifests as ulcerative skin lesions. We describe one such unusual case of a young male who presented with multiple ulcers and maculo-papular rash over the legs, chest and abdomen. In addition to this, he had fever, heart murmur, pulmonary infiltrates, neuropathy, and deranged liver function. A clinical differential diagnosis of infective endocarditis and systemic nectrozing vasculitis was made. Skin biopsy showed dense inflammation with lepra bacilli consistent with type-2 lepra reaction.

Abstract
OBJECTIVES Anthropometric and physiological profiles of national sepak takraw players were determined. METHODS Thirty nine players, specialising in the three playing positions (tekong/server, feeder, and killer/spiker) were divided into three age categories of under 15 (U15), under 18 (U18), and under 23 (U23) years of age. Height, weight, percent body fat (%bf), maximum oxygen consumption (Vo(2max)), range of motion (ROM), back and leg strength, and heart rate, for the estimation of oxygen consumption during matches, were recorded. Statistical analysis was performed using one way ANOVA for independent measurements and data are presented as mean+/-standard deviation. RESULTS The U23 players were significantly taller and heavier with significantly better ROM of the neck, trunk, and ankle joints and back and leg strength than the U15 players. No significant difference was found in %bf between the three age categories. Mean maximum heart rate during exercise was significantly higher in the U15 group when compared to the U18 and U23 groups (p<0.05). Mean Vo2max was similar between the three groups. Estimated oxygen consumption during matches was 69.1%, 68.5%, and 56.4% of Vo2max in the killer, tekong, and the feeder groups, respectively. CONCLUSIONS The mean height, body weight, and cardiopulmonary capacities of the players were within the Malaysian population norms, but were somewhat lower than those of players of other court games from other countries. %bf was also lower in these players. This study provides the much needed anthropometric and physiological data of sepak takraw players for further development of this sport.

Abstract
BACKGROUND Problems of maternal and foetal genotype differentiation of maternal plasma in pregnant women are solved generally by real-time systems. In this case the specific probes are used to distinguish particular genotype. Mostly gonosomal sequences are utilised to recognise the male foetus. This work describes possibilities in free foetal DNA detection and quantification by STR. METHODS AND RESULTS Artificial genotype mixtures ranging from 0,2 % to 100 % to simulate maternal and paternal genotypes and 27 DNA samples from pregnant women in different stage of pregnancy were used for DNA quantification and detection. Foetal genotype was confirmed by biological father genotyping. The detection was performed in STR from 21st chromosome Down syndrome (DS) responsible region by innovated (I) QF PCR which allows to reveal and quantify even very rare DNA mosaics. The STR quantification was assessed in artificial mixtures of genotypes and discriminability of particular genotypes was on the level of few percent. Foetal DNA was detected in 74 % of tested samples. CONCLUSIONS The IQF PCR application in quantification and differentiation between maternal and foetal genotypes by STR loci could have importance in non-invasive prenatal diagnostics as another possible marker for DS risk assessment.

Abstract
BACKGROUND AND AIMS In acute liver failure (ALF), the brain is exposed to high levels of ammonia. Human studies defining the clinical significance of ammonia in ALF are lacking. This prospective study evaluated the relationship of arterial ammonia levels at admission to complications and survival among patients with ALF. METHODS Eighty consecutive ALF patients admitted from March 2001 to December 2003 were followed up until death or complete recovery. All had arterial ammonia estimation at admission (enzymatic method). Logistic regression analysis was performed to identify independent predictors of mortality. RESULTS Forty two (52.5%) patients died. Non-survivors had significantly higher median ammonia levels than survivors (174.7 v 105.0 micromol/l; p<0.001). An arterial ammonia level of > or = 124 micromol/l was found to predict mortality with 78.6% sensitivity and 76.3% specificity, and had 77.5% diagnostic accuracy. Patients with higher ammonia levels also developed more complications, including deeper encephalopathy (p = 0.055), cerebral oedema (p = 0.020), need for ventilation (p<0.001), and seizures (p = 0.006). Logistic regression analysis showed that pH, presence of cerebral oedema, and arterial ammonia at admission were independent predictors of mortality (odds ratios 6.6, 12.6, and 10.9, respectively). Incorporating these variables, a score predicting mortality risk at admission was derived: 2.53 + 2.91 ammonia + 2.41 oedema + 1.40 pH, where ammonia is scored as 0 (if <124 micromol/l) or 1 (if > or =124 micromol/l); oedema is scored as 0 (absent) or 1(present); and pH is scored as 1 (if < or =7.40) or 0 (if >7.40). Levels of partial pressure of ammonia were equally correlated with outcome. CONCLUSION Arterial ammonia at presentation is predictive of outcome and can be used for risk stratification. Ammonia lowering therapies in patients with ALF should be evaluated.

Abstract
INTRODUCTION Pregnancy and lactation-associated osteoporosis (PLO) is an uncommon condition characterized by the occurrence of fracture(s) during late pregnancy or the puerperium. The aetiology is uncertain, and its management and natural history poorly defined. METHODS We report a series of 11 women with PLO seen at our institution over the past 20 years, with follow-up ranging from 1 to 19 years. RESULTS Ten women presented with painful low-trauma vertebral fractures, at a median of 1 month postpartum. In nine cases the fractures were multiple (median: 3, range: 2-5). At least one recognised risk factor for osteoporosis (low body weight, smoking history, family history of osteoporosis/fracture, vitamin D insufficiency) was present in nine patients. Bone density was in the osteoporotic range at the spine (mean T score: -2.8), with less marked reduction at the proximal femur (mean T score: -1.9). Nine patients received bisphosphonate treatment, for a median duration of 24 months. In the five women who received a bisphosphonate within 1 year of presentation, spinal bone density increased by 23% over baseline values after 2 years of treatment (p=0.0014). Of the 5 women who had subsequent pregnancies, one, who had declined bisphosphonate therapy after the initial presentation, sustained a fracture in the postpartum period. Two patients (both of whom were followed for at least 10 years) sustained fractures outside of pregnancy. CONCLUSIONS PLO is therefore associated with significant morbidity, a high prevalence of recognized risk factors for osteoporosis and a risk of recurrence in subsequent pregnancies. Bisphosphonate therapy administered soon after presentation substantially increases spinal bone density in patients with PLO.

Abstract
The role played by dendritic cell (DC) subsets in the immune response to alloantigens is not well defined. In vitro experiments have extensively shown that freshly isolated myeloid (M)DCs induce a strong T lymphocyte proliferation whereas plasmacytoid (P)DCs do not, unless activated by CD40 ligation. The aim of these studies was to explore whether the interplay among PDCs, MDCs and T cells modulates alloresponse. Freshly isolated MDCs and PDCs were merged in different proportions and used as antigen presenting cells (APCs) in mixed lymphocyte cultures (MLC). As described, isolated PDCs only induced a mild alloresponse, while MDCs were potent inducers of alloproliferation. Unexpectedly, when PDCs were merged with even low numbers of MDCs (down to 100 cells) and used as APCs, a potent Th1 cell proliferation was detected. Survival and maturation of PDCs was increased in these MLC conditions, which could partially explain the magnitude of the T-cell response. Interestingly, the proportion of IFNgamma-producing cells generated in such cultures was higher compared to MDC-stimulated cultures. These data suggest that the interaction between both DC subsets is determinant to generate a potent Th1 response, at least in an allogeneic situation, and may be relevant to the outcome of allogeneic stem cell transplantation.

Abstract
PURPOSE To study the corneal topographic response to IOP reduction in vernal keratoconjunctivitis (VKC) with steroid-induced glaucoma. METHODS A total of 42 eyes of 21 patients with VKC and steroid-induced glaucoma (Group I) and 66 eyes of 33 patients with VKC without glaucoma (Group II) underwent an evaluation by Orbscan topography. In eyes with glaucoma, the IOP was controlled medically and the corneal topography was repeated at 3 months to evaluate effect on corneal parameters. RESULTS The mean baseline IOP was 36.40+/-13.08 mmHg in Group I, 14.67+/-4.62 mmHg in Group II (P<0.0001). The IOP after treatment at 3 months follow-up was 15.00+/-5.41 mmHg in Group I (P<0.0001). In Group I, the mean maximum Sim K decreased from 44.86+/-3.21 D to 43.87+/-2.62 D (P=0.031) and mean posterior corneal elevation decreased from 64.9+/-22.36 microm to 35.7+/-28.91 microm at 3 months after reduction of IOP (P=0.001). There was a significant positive correlation between the reduction in the IOP and the decrease in the posterior corneal elevation (r=0.664, P=0.001). CONCLUSION Eyes with VKC with and without glaucoma have similar corneal topography. Increased IOP associated with steroid-induced glaucoma and VKC may contribute to an increase in the corneal curvature and posterior corneal elevation. These changes may be reversed by a reduction in the IOP with medical therapy.

Abstract
BACKGROUND Blood pressure (BP) measurement is a routine procedure but errors are frequently committed during BP recording. AIMS AND SETTINGS: The aim of the study was to look at the prevalent practices in the institute regarding BP recording. The study was conducted in the Medicine Department at Government Medical College, Chandigarh, a teaching institute for MBBS students. METHODS A prospective, observational study was performed amongst the 80 doctors in a tertiary care hospital. All of them were observed by a single observer during the act of BP recording. The observer was well versed with the guidelines issued by British Hypertension Society (BHS) and the deviations from the standard set of guidelines issued by BHS were noted. The errors were defined as deviations from these guidelines. STATISTICAL METHODS The results were recorded as percentage of doctors committing these errors. RESULTS In our study, 90% used mercury type sphygmomanometer. Zero error of the apparatus, hand dominance was not noted by any one. Every one used the standard BP cuff for recording BP. 70% of them did not let the patient rest before recording BP. 80% did not remove the clothing from the arm. None of them recorded BP in both arms. In out patient setting, 80% recorded blood pressure in sitting position and 14% in supine position. In all the patients where BP was recorded in sitting position BP apparatus was below the level of heart and 20% did not have their arm supported. 60% did not use palpatory method for noticing systolic BP and 70% did not raise pressure 30-40 mm Hg above the systolic level before checking the BP by auscultation. 80% lowered the BP at a rate of more than 2 mm/s and 60% rounded off the BP to nearest 5-10 mm Hg. 70% recorded BP only once and 90% of the rest re inflated the cuff without completely deflating and allowing rest before a second reading was obtained. CONCLUSION The practice of recording BP in our hospital varies from the standard guidelines issued by the BHS.

Abstract
Natural occurrence of yellow mosaic disease was observed on bitter gourd (Momordica charantia). Association of geminivirus with the disease was investigated through polymerase chain reaction using geminivirus-specific primers and Southern hybridization with a probe prepared from the cloned DNA of a known geminivirus. The fruits, leaves and stem of infected and healthy plants were studied for phytochemical composition. The amounts of protein were 49%, 50% and 66% higher, total carotenoids were 36%, 33% and 40% lower, vitamin C were 23%, 48% and 50% lower, total phenols were 28%, 31% and 43% lower, and antioxidant activity were 36%, 48% and 43% lower in the severely virus infected fruits, leaves and stem, respectively, as compared with healthy plants. The loss in the quantity of these phytochemicals was also observed even in mild infected plants, which further increased with the severity of the symptoms. Similarly, ethanol and 50% ethanol soluble extractive were also 25-43% lower in the fruits, leaves and stem of infected plants as compared with the healthy plants. A 45% and 54% lower caffeic acid, and 78% and 59% lower amounts of ferulic acid in the fruits and stem, respectively, and a 25% loss of gallic acid were noticed in the leaves of the severely infected plants.
