Inflammatory bowel disease (IBD) is the chronic inflammatory disorder of gastrointestinal tract consisting of two subtypes: Ulcerative colitis and Crohn's disease. IBD occurs due to infiltration of leukocytes in intestinal mucosa and derangements in intestinal barrier function. One of the most important steps in pathogenesis of IBD is the interactions between integrins on the surface of leukocyte. The α₄β₇ integrin expressing T-cell is an important leukocyte involved in pathogenesis and represents a new drug target for the treatment of IBD. Vedolizumab is a humanized monoclonal antibody, which acts against α₄β₇ integrin heterodimer and blocks the interaction of α₄β₇ integrin with MAdCAM-1. It prevents leukocyte binding to endothelial surface and its extravasation into affected tissue. The efficacy and safety of the vedolizumab have been established in many clinical studies. It has shown promising results in various clinical studies where a greater percentage of patients as compared to a placebo achieved and maintained clinical response, clinical remission, and corticosteroid-free clinical remission. Vedolizumab has been shown to be well tolerated with slightly higher risk of infections, headache, naspharyngitis as compared to placebo. This review focuses on the potential role of vedolizumab for the treatment of IBD.

In recent years, there has been a shift in the donor demographics with an increase in donation after circulatory death (DCD). Livers obtained from DCD donors are known to have poorer outcomes when compared to donors after brainstem death and currently only a small proportion of DCD livers are used. This review outlines the recent technological developments in liver DCD donation, including clinical studies using normothermic regional perfusion and extracorporal machine perfusion of livers from DCD donors.

Objectives: The objective of the study was to report the incidence of pediatric burn injuries and describe the pattern and the trend of pediatrics burns seen in King Abdul-Aziz Medical City. Materials and Methods: Retrospective cross-sectional study. Data collected through chart review of pediatrics patients aged 1-month to 14 years who presented with a burn injury to the pediatric emergency department during the year 2013. Burn patients were divided into two groups based on the percentage of total body surface area (TBSA) burned: Either <10% or more than 10%. Variables were compared between the two groups to identify the risk factors associated with more than 10% body surface area involvement. Results: Burn incidence rate was 4.9 patients/1000/year. Children with burns on more than 10% TBSA accounted for 16% incidence (0.8/1000 emergency department patients). The burn injury severity ranged from 1% TBSA to 37%, with a mean of 5%. The proportion of male and female burn patients was 54.1% and 45.9%, respectively. Children between 1 and 3 years of age sustained the majority (48.6%) of burn injuries. Scald burns were found to be the most common cause of injury. Hot water and beverages were considered root for most of the scald burn injuries. As children advance in age, scald injury becomes less likely, and they are more obviously subjected to flame burn injuries. Burn injuries sustained at home were 35% compared to 2.7% occurring outside the home. None of the study variables were good predictors for severe burn injuries affecting more than 10% TBSA. Conclusion: The incidence and the severity of burn injuries remain high at the national level. Burn injuries continue to affect the pediatric population, predominantly, young children, which indicate the need for increasing parent educational programs and government regulations. Because we reported scald burns as the most common causes of burn injury, which are consistent with previous national reports, we recommend having legislation that focuses on scald burn prevention.

Background and Objectives : Urinary tract infection (UTI) is one of the most frequent infectious diseases and can occur in all age groups. Escherichia coli is the main cause of this infection. Multiple resistances to antimicrobial agents are increasing quickly in E. coli isolates and may complicate therapeutic strategies for UTI. The aim of this study was to determine the antibiotic resistance pattern and the multidrug-resistance (MDR) phenotypes in uropathogenic E. coli (UPEC). Materials and Methods : A total of 135 UPEC isolates were collected from both outpatients (91 isolates) and inpatients (44 isolates) between September, 2012 and February, 2013. In order to determine the MDR among UPEC isolates, we have tested 15 antimicrobial agents and antibiotic susceptibility was done by Kirby-Bauer disk diffusion method. Results : The percentage of MDR isolates (resistant to at least three drug classes such as aminoglycosides, fluoroquinolones, penicillins, cephalosporins, or carbapenems) was 68% in the inpatients and 61% in the outpatients. Antibiotic resistance to ampicillin, ceftazidim, nalidixic acid, and trimethoprim/sulfamethoxazole were higher than 50%. Amikacin, nitrofurantoin, and gentamicin showed markedly greater activity (89.1%, 85.9%, and 82.4% sensitivity, respectively) than other antimicrobial agents. Resistance to meropenem did show either in outpatients or in inpatients. Interpretation and Conclusions: The high prevalence of drug resistance among UTI patients calls for continuous monitoring of the incidence of drug resistance for appropriate empiric selection of antibiotic therapy. Empirical treatment of UTIs should be relied on susceptibility patterns from local studies.

Background: Vitiligo is one of the common stigmatizing dermatosis in the Indian society and the vitiligo patients have to face significant psychological hurt and social neglect. The severity of the stigma is related to the society's attitude and knowledge about it. Aims and Objectives: To document the prevalent knowledge and attitude in general public towards vitiligo patients, and to identify the determinants of good/poor knowledge and attitude. Materials and Methods: A systematic random sampling technique was adopted to enroll 700 adult participants visiting an urban tertiary healthcare facility of central India. We developed a questionnaire to collect information on knowledge and attitude of the participants. A composite score was developed for good knowledge and attitude and performance of the participants was compared with the selected determinants. Data analysis was conducted by Stata software version 11. Results: The overall knowledge score was good for 66.3% (95% confidence interval [CI]: 62.8%, 69.8%) of the participants. However, the score for attitude was comparatively poor i.e., only 16.9% (95% CI: 13.9%, 19.5%). None of the studied parameters could be significantly correlated with the knowledge score. Being married and being engaged in a health care related occupation were significant predictors of good attitude levels with P = 0.042 and 0.034 respectively, whereas female gender was the significant predictor for poor attitude with an odds ratio of 0.54 (95% CI: 0.33, 0.9) and P = 0.018. Conclusions: There were widespread myths prevalent about vitiligo in the studied population. The knowledge scores were better than attitude scores.

Context: The assessment of micronuclei (MN) in exfoliated oral epithelial cells is a promising tool for the study of epithelial carcinogens and can be used to detect chromosome breakage or mitotic interference, thought to be relevant to carcinogenesis. Aims: To detect MN in exfoliated oral mucosal cells in individuals using various tobacco forms and also to detect frequency of MN in premalignant lesions and conditions (potentially malignant diseases [PMD's]) and oral squamous cell carcinoma (OSCC). To correlate frequency of MN in oral exfoliated cells in clinically diagnosed cases of OSCC followed by a histopathological grading. Materials and Methods: A total of 90 subjects (30 smokeless tobacco users, 30 smokers and 30 nontobacco users) consisted of clinically diagnosed cases of PMD's and OSCC were selected for the study. Cytosmears from the groups were stained with rapid Papanicolaou stain. MN was identified according to the Tolbert et al. criteria. Results: MN cells were found to be significantly higher in smokeless tobacco users than in smokers. The frequency of MN was three to four times higher in patients with OSCC as compared to patients in PMD's (P < 0.0001). The frequency of MN correlated with the histopathological grade was statistically significant. Conclusion: MN index can be used as a biomarker/screening test among the high-risk groups particularly the smokeless tobacco users and PMD's. MN can be a candidate to serve as a biomarker for prediction of the grade of OSCC.

Background: In our country, the problem of antibiotic resistance is compounding because of overuse and misuse of antibiotics. There is no systematic national surveillance of antibiotic resistance and insufficient data are available to quantify the problem. Objectives: To study the changing pattern of antimicrobial resistance of Klebsiella pneumoniae isolates from patients of urinary tract infections over last 3 years. Materials and Methods: A retrospective, record-based study carried out based on the records culture sensitivity reports of indoor patients, during past 3 years (2012-2014). The type of organisms most common in urine sample was noted, and the drugs still effective for the particular organism were noted. Results: Klebsiella was the second most frequent isolate throughout the 3 years (14%) of the total isolates). Analysis of the results year wise indicated that the lowest percentage of resistance was manifested against imipenem between 11.94% (2012) and 13.75% (2014). Over the successive years, resistance to ceftriaxone tends to increase from 74.95 % (2012) to 81% (2014). Klebsiella showed very high resistance 90.78% (2012) and 95.63% (2012) to co-trimoxazole and tetracycline, respectively with increasing trend to absolute resistance to both groups over the 3 years period. On an average over the 3 years Klebsiella showed a high amount of resistances to fluoroquinolones (72.71%) and aminoglycosides (76.22%). While multi-drug resistant Klebsiella range between 65% (2012) and 67% (2014). Conclusion: The antimicrobial resistance patterns are constantly evolving and vary from region to region it has become a necessity to do constant antimicrobial sensitivity surveillance. This will help clinicians to provide safe and effective empirical therapies.

Background: Dermatoglyphics and bronchial asthma (BA) are both influenced by genetic factors. Hence, we assessed the diagnostic potential of correlation between fingerprint pattern and BA. Materials and Methods: The study was carried out in out-patient Department of Pulmonary Medicine of All India Institute of Medical Sciences Bhopal. It included 36 patients of BA and 50 nonasthmatic individuals as controls. The following parameters were studied and analyzed: (a) Whorls, (b) arches, (c) radial loops, (d) ulnar loops, (e) the absolute finger ridge count (AFRC), (f) total finger ridge count (TFRC). Results: A significant decrease in the mean value of the arches and increase in the mean value of the ulnar loops were observed in BA patients compared to the control group. The mean values of TFRC, AFRC, and whorls were similar in both groups. Conclusion: Evaluation of dermatoglyphic patterns may be useful in identifying patients prone to developing BA.

Background: Liquid extract of Morinda lucida leaf has been demonstrated to have antiplasmodial activities. Some phytochemicals act as preventive and or scavenging antioxidants. This study aimed to investigate the preventative and scavenging properties of the raw liquid extract of M. lucida leaf using plasma myoglobin, transferrin, superoxide dismutase (SOD), and glutathione (GSH) peroxidase. Materials and Methods: Forty-eight Plasmodium-infected patients aged 29-47 years that have not been treated with any antimalaria medication but have decided to be treated traditionally using M. lucida leaf extract were recruited from 15 traditional homes in ATISBO, Saki-East, and Saki-West local government areas of Oke-Ogun - the Northern part of Oyo State-Nigeria. Identification of Plasmodium in the blood of the test and normal control subjects were carried out by Giemsha thick film technique. Packed cell volume, total bile acids, blood glucose, blood pressure, plasma myoglobin, transferrin, SOD, and GSH peroxidase (GPx) were evaluated in the normal control subjects and in the Plasmodium-infected patients before and after the treatment with raw liquid extract of M. lucida leaf. Results: A significant (P < 0.05) biochemical alterations were observed in the plasma values of transferrin, SOD, and GPx in the Plasmodium-infected patients when compared with the normal control subjects and after treatment with the raw liquid extract of M. lucida leaf. Conclusion: Our study supports the possible preventative and scavenging antioxidative effect of the raw liquid extract of M. lucida leaf in the traditional treatment of Plasmodium infection.

Background: Honey has previously been shown to have wound healing and antimicrobial properties, but this is dependent on the type of honey, geographical location, and flower from which the final product is derived. We tested the antimicrobial activity of a natural honey originating from the Ziziphus spina-christi tree, against selected strains of bacteria. Ziziphus honey among more than a 100 verities of honey is known to have the greatest value of energy and minerals in it. Materials and Methods: The aim of this study was to determine the antibacterial activity of Ziziphus honey in 10%, 20%, 30%, and 40% dilutions (v/v) against Listeria monocytogenes, Salmonella typhimurium, Escherichia coli, and Staphylococcus aureus. Viable count enumeration of the sample was investigated after 0, 24, 72, and 120 h postinoculation with any of the bacteria using pour-plate method. Results: The findings indicate that Ziziphus honey was effective against these pathogenic bacteria. In a comparative trial, antibacterial activity of Ziziphus honey was higher after 120 h incubation for each four bacteria in most dilutions. The microbial count showed 3-7.5 log reduction comparing with control after 120 h. Conclusions: Therefore, it is recommended using Ziziphus honey as a natural preservative and antibacterial agent. Also, it could potentially be used as therapeutic agents against bacterial infection particularly to the tested microorganisms.

Background: Acinetobacter baumannii which is a Gram-negative bacterium can cause several different infections. The appearance of carbapenemase-producing A. baumannii in recent years has made the treatment process more difficult. The identification of virulence factors (VFs), such as nonadhesives in A. baumannii, helps to fight against related infections. Materials and Methods: A total of 104 samples from teaching hospitals in Kermanshah, Iran, were collected during a 24 months period (2011-2013). Sample identification was first carried out by biochemical tests, and then their susceptibility to carbapenems was determined using the Kirby-Bauer method. For confirmation of carbapenemase-producing A. baumannii, polymerase chain reaction (PCR) was done for carbapenemase-encoding genes. In addition, the frequency of nonadhesive VFs in carbapenemase-producing isolates was determined by PCR. Results: There were 50 isolates that were identified as carbapenemase-producing A. baumannii. The PCR results showed; 40 isolates (80%) for traT, 17 isolates (34%) for cvaC, and 8 isolates (16%) for iutA, and these encode serum resistance, colicin V and aerobactin, respectively. No significant correlation was observed between these three genes. Conclusions: The mechanism of A. baumannii virulence has always been in question. The role of VFs has also been recognized in other Gram-negative bacteria. According to the prevalence of traT, cvaC and iutA, as nonadhesive VFs, we can suggest that they could be the main mechanism of carbapenemase-producing A. baumannii pathogenesis.

Background: Metabolic syndrome is commonly associated with cardiovascular diseases and psychiatric mental illness. Hence, we aimed to assess the metabolic syndrome among severe mental illness (SMI). Materials and Methods: The study included 267 patients who were referred to the psychiatric unit at 5 ^th Azar Education Hospital of Golestan University of Medical Sciences in Gorgan, Iran. Results: The mean waist circumference, systolic and diastolic blood pressure, triglyceride and fasting blood glucose levels were significantly higher in the SMI with metabolic syndrome, but the high density lipoprotein (HDL)-cholesterol was significantly lower. The prevalence of metabolic syndrome in SMI patients was 20.60%. There were significant differences in the mean of waist circumference, systolic (except for women) and diastolic blood pressure, triglyceride, HDL-cholesterol and fasting blood glucose in men and women with metabolic syndrome when compared with subjects without metabolic syndrome. The prevalence of metabolic syndrome in SMI women was higher than men. The most age distribution was in range of 30-39 years old. The most prevalence of metabolic syndrome was in age groups 50-59 years old. The prevalence of metabolic syndrome was increased from 30 to 59 years old. Conclusion: The prevalence of metabolic syndrome in patients with SMI in Gorgan is almost similar to those observed in Asian countries. The prevalence of metabolic syndrome was lower than western countries. These observations may be due to cultural differences in the region. It should be mention that the families of mental illness subjects in our country believe that their patients must be cared better than people without mental illness. These findings of this study suggest that mental illness patients are at risk of metabolic syndrome. According to our results, risk factors such as age and gender differences may play an important role in the presence of metabolic syndrome. In our country, women do less physical activity than men; therefore, the incidence of metabolic syndrome is higher among women.

Background: Diabetes is the fifth leading cause of death in the world. Hence, we investigated the factors affecting disease control among diabetic patients referred to Imam Reza Hospital (central hospital in the Northwest of Iran). Materials and Methods: One hundred and eight diabetic patients were evaluated. Patient's main medications including insulin, metformin, glibenclamide, and glytazon were registered and the levels of fasting blood sugar (FBS), glucose 2 h postprandial (pp), and hemoglobin A1c (HbA1c) were measured. All risk factors were evaluated by using a questionnaire completed by the patients. Results: The average of HbA1c, FBS, and glucose 2 h pp was 7.33%, 159 mg/dl, and 233.03 mg/dl, respectively. In patients whose disease was controlled, the family history of the disease, the type of medication, and the visits to family physician had a significant association with disease control. The average mean of HbA1c among patients with controlled and uncontrolled disease was 5.93% and 8.63 % respectively. Conclusion: Less stress, education, and weekly exercise had an essential role in controlling the disease in diabetic patients from the Northwest of Iran and noncompliance with the prescribed diet by the physician and lack of timely medicine intake were the main reasons for uncontrolled disease.

Background: Hepatitis B virus (HBV) and hepatitis C virus (HCV) infections represent significant public health issues globally. They are important causes of morbidity and mortality in hemodialysis patients. Patients with HBV/HCV co-infection have a higher risk of progression to cirrhosis and decompensated liver disease and have an increased risk of hepatocellular cancer (HCC). Because the two hepatotropic viruses share same modes of transmission, co-infection with the two viruses is not uncommon, especially in areas with a high prevalence of HCV infection and among people at high-risk for parenteral infection. Aims: To estimate the prevalence of HBV and HCV co-infection among hemodialysis patients. Materials and Methods: This retrospective, single centered hospital record-based study was carried out in a tertiary care hospital in Faridkot (Punjab), India. All the patients who underwent hemodialysis from January 2013 to December 2014 were included in the study. Patients of all age groups were tested for anti-HCV antibodies by fourth Generation HCV Tridot ELISA (J. Mitra & Co. Pvt. Ltd., New Delhi, India) and for hepatitis B surface antigen (HBsAg) by Hepalisa (J. Mitra & Co. Pvt. Ltd). Results: Of the total 262 patients on hemodialysis, 88 (33.5%) were found to be having HCV infection, 4 (1.5%) were found to be positive for HBsAg. Co-infection with HBV/HCV was observed in 2 (0.8%) patients. Out of the total 92 patients having HBV and HCV infection, 62 (67.4%) were males and 30 (32.6%) were females. The majority of the patients were found to be of 41-60 years of age (41.3%) followed by 21-40 years (31.5%) and thereafter in 61-80 years (23.9%) and lowest prevalence was observed in the age group of <20 years (2.2%) and >80 years (1.1%). Conclusion: The risk of co-infection is greater among the chronic renal failure (CRF) patients due to the high frequency of transfusions of blood/blood products and extracorporeal circulation during hemodialysis. Patients with HBV/HCV co-infection have a higher risk of progression to cirrhosis and decompensated liver disease and further have an increased risk of HCC. In our study, out of the total 262 patients, 88 (33.5%) were found to be having HCV infection, 4 (1.5%) were found to be positive for HBsAg and dual infection was observed in 2 (0.8%) patients which is higher than the rates reported from different studies all over the world and India.

Background: Among the manifold uses of mobile phones, mobile-health (mHealth) has been an important one, which is the practice of public health initiatives by awareness raising and communication campaigns. Optimum utilization of mHealth is possible only through adequate awareness. Hence, we aimed to study the perceptions and knowledge about mHealth among college going students in Mangalore, India. Materials and Methods: A cross-sectional study was conducted in March 2014 among 627 students in selected engineering (302 students) and medical colleges (325 students) in Mangalore, India. Colleges were selected using convenience sampling (nonrandom) method. Data were collected using semi-structured self-administered questionnaire and analyzed. Results: Overall, 48.9% were males, 61.4% belonged to 18-20 years age group. The awareness about mobile phone health utilities among medical and engineering students was found to be similar. Among those who were aware of the concept of mHealth (74 [11.2%]), 40 (54.1%) were medical students. Marginally higher proportion of medical students felt mHealth could be helpful in protecting the patients' confidentiality and would help in better communication with the patients. Conclusion: There was high level of general awareness about mHealth among the subjects. However, many specific areas had limited knowledge among both the streams of students, hence highlighting the need for increasing awareness and sensitization.

Background: Prevalence of subclinical hypothyroidism (SCH) in pregnancy varies widely in different parts of our country, but it has multiple adverse outcomes in both the mother and fetus. Objectives: This study was conducted to evaluate the prevalence of SCH in pregnant women during the first trimester and to identify the prevalence of thyroid autoimmunity in pregnant women. Materials and Methods: This cross-sectional study (March 2014 to February 2015) was conducted among the pregnant women attending antenatal clinic in their first trimester at a tertiary care center. Morning samples of study participants were analyzed for free thyroxin (FT4), thyroid stimulating hormone (TSH), and thyroid peroxidase antibody (TPO Ab). Data expressed as mean ΁ standard deviation and percentage (%) as applicable. Results: Of the 510 subjects, 168 had TSH value >2.5 μIU/ml (32.94%) with normal FT4 and they were diagnosed as SCH. TSH level >4.5 μIU/ml was estimated in 13.92% (71) of the subjects. TPO Ab was positive in 57 (33.93%) of subclinical hypothyroid and 5 (1.47%) of normal subjects. 70.42% (50) of the subjects with TSH >4.5 μIU/ml had positive TPO Ab. Conclusions: Prevalence of SCH is high in South Bengal and routine thyroid screening at the first antenatal visit should be done to reduce the social and financial burden caused by SCH.

Background: Amphotericin B (AmB) is a polyene antibiotic frequently applied in the treatment of systemic fungal infections in spite of its secondary effects. The pH plays a crucial role in modulating biophysical features of ion channels in the bilayer lipid membranes. Aim: In this study, the role of pH in the regulation of AmB channel was assessed by single channel recording of ion channel incorporated in the artificial membrane. Materials and Methods: Bilayer lipid membrane was formed by phosphatidylcholine in a 350 ΅m diameter aperture between two chambers, cis and trans contained 200/50 mMKCl solutions, respectively; then AmB was incorporated into the bilayer lipid membrane. Single channel recordings were used to indicate the effects of pH changes on AmB channels activity. The records were analyzed by Clamp fit 10 software. Results: A kinetic analysis of single channel currents indicated a cation ion channel with 500 pS conductance and voltage-dependence of the open probability of the AmB channel (P_o ). A reduction of cis pH to 6 decreased P_o and conductance. This effect was also voltage-dependent, being greater at a more positive above −40. The pH changes in the range of 6-8 had no effect on the reversal potential and ion selectivity. Conclusion: Our data indicated that extracellular acidity can reduce AmB activity.

Aim: Azoospermia is the most common form of male factor infertility, due to which sperms are retrieved for intra-cytoplasmic sperm injection (ICSI) under general or local anesthesia. The aim of the present study was to compare the efficacy of general and local anesthesia in an attempt to extract a sufficient quality of sperm for men with azoospermia, who intend to undergo ICSI. Materials and Methods: A total number of 50 patients with azoospermia, who were within the age range of 20-40, were randomly scheduled for testicular sperm extraction with either general or local anesthesia before ICSI. The hormonal abnormalities and severe varicocele were evaluated and treated before the testicular sperm extraction. The inclusion criteria obliged the researchers to focus on men with azoospermic, those who were diagnosed by two semen analyses after a 3-day abstinence from coitus according to the modified WHO criteria, and 19< body mass index ≤28. The concentration, motility, and morphology of the spermatozoa of the two groups were also compared. Results: A total number of 76 men, with a mean age of 35.1 ΁ 6.0, were selected, 26 were excluded from the study, and the remaining participants were randomly divided into two groups such as general anesthesia and lidocaine group. According to the results, the differences between the values of sperm parameters within various hours after the testicle biopsy were not statistically significant. Also, there was no significant difference between the two groups in terms of sperm motility and sperm morphology during various timing after the processing. Conclusion: The present study demonstrated that there was no evidence found for values of sperm parameters between the two groups, undergoing local and general anesthesia, within various hours after the testicular biopsy. Further investigations with more focus on concentration-dependent lidocaine on human sperm parameters need to be carried out.

Background: Drug information can be obtained from various sources such as National Formularies, drug package inserts (PI), other sources such as Monthly Index of Medical Specialities (MIMS), Current Index of Medical Specialities, and the information available with the regulators. Any variation in the information available in different sources can promote irrational drug use. In this study, we assessed this variation in a sample of commonly used drugs. Materials and Methods: Fifty commonly used drugs were analyzed for any variation (both quantitative and qualitative) in information on indications as mentioned in commonly used drug information sources such as Central Drugs and Standards Control Organization (CDSCO) website, National Formulary of India (NFI), MIMS, and PI of medicines. Results: We observed a variation in average number of indications per drugs given in CDSCO (2.2 ± 0.25), NFI (3.51 ± 0.42), MIMS (2.98 ± 0.29), and PI (3.18 ± 3.52). The CDSCO and NFI did not contain information about indication for 10 and 17 drugs, respectively, while MIMS and PI contained information about all the selected drugs. A subset analysis was done for 24 such drugs which were mentioned in all the four sources and it was found that NFI had listed the maximum number of indications per drug (3.79 ± 0.53), followed by PI (3.08 ± 0.44), MIMS (3.04 ± 0.51), and CDSCO website (2.66 ± 0.37) and this difference was found to be statistically significant (P = 0.02). We also observed some gross qualitative variation regarding drug information given in different sources. Conclusion: Variation exists in the quantity and quality of information available on indications about drugs available in various sources. Necessary steps need to be taken to harmonize drug information available across various sources so as to provide reliable and uniform drug information thereby promoting rational drug use.

Rhinosporidiosis is a chronic localized granulomatous disease caused by Rhinosporidium seeberi, an aquatic protistan parasite belonging to a clade, Mesomycetozoea. Infestation of Rhinosporidiosis to the eye and adnexa is termed oculosporidiosis, in such cases, conjunctival mucosa is mostly involved; however in our case, it involved only the lacrimal sac and deeper periorbital tissue and presented as a case of orbital swelling. Surgical excision of the lesion was done, postoperatively dapsone therapy was given for 6 months, and the patient responded very well with no recurrence till date.

Abnormalities in the root canal anatomy are commonly occurring phenomenon. A thorough knowledge of root canal anatomy and its variation is necessary for successful completion of endodontic treatment. Mandibular anteriors are known for having extra canals. The role of genetics and racial variations may result in difference of incidence of root number and canal number. This paper attempts at explaining a rare case of successful endodontic management of two-rooted lateral incisor with awareness of data pertaining to number of canals, knowledge of canal morphology, correct radiographic interpretation, and tactile examination of canal wall which are important in detecting the presence of multiple canals.

A middle-aged female patient from West Bengal presented with complaints of redness, foreign body sensation, and watering for 2 days in the left eye. Slit lamp examination of the left eye revealed several minute white foreign bodies moving over the bulbar conjunctiva. Removal of the foreign bodies under local anesthesia, followed by microscopic examination, suggested the presence of first instar larvae of Oestrus ovis; the sheep nasal bot fly. Diagnosis of unilateral external ophthalmomyiasis was made. Such cases though very infrequently have been reported in the past from Southern and Central Part of India. To the best of our knowledge, this is the second report from Eastern India. A high index of suspicion is necessary both on the part of the clinician and the microbiologist for correct diagnosis.

The esthetic concern of severely mutilated primary anterior teeth in the case of early childhood caries has been a challenge to pediatric dentist. Early childhood caries is the most common chronic disease of the preschool child. The case report presented here is of a three year old boy with severely decayed maxillary anterior teeth. After root canal treatment, the primary maxillary central incisors were reinforced using modified omega post and followed by using celluloid strip crowns. The technique described here offers a simple and effective method for restoring severely decayed primary anterior teeth that reestablishes shape, function, and esthetics.

The artery of Percheron (AOP) is a rare vascular variant in which a single dominant thalamoperforating artery arises from the P1 segment and bifurcates to supply both paramedian thalami. Occlusion of this uncommon vessel results in a characteristic pattern of bilateral paramedian thalamic infarcts with or without mesencephalic infarctions. We report a case of a 37-year-old man with acute bilateral thalamic infarcts. The scans revealed symmetric bilateral hyperintense paramedian thalamic lesions consistent with an acute ischemic event. The posterior circulation was patent including the tip of the basilar artery and both posterior cerebral arteries, making the case compatible with occlusion of the AOP. This type of infarct is associated with embolic phenomena, and further evaluation revealed a patent foramen ovale as the source of emboli in the cerebrovascular circulation. The occlusion of the AOP is a rare cause of coma in young patients, and early recognition of this rare disease entity may lead to more favorable outcomes.
