Diphtheria: It is still prevalent!!!

BACKGROUND

Diphtheria is a respiratory infectious disease of childhood. It is a fatal disease and may cause complications if not recognized early and treated properly. Despite availability of effective vaccination it continues to be reported from many parts of the world particularly developing countries.

OBJECTIVE

To assess the demographic and clinical characteristics of diphtheria patients, and the predictors of outcomes of respiratory diphtheria.

METHODS

A prospective analysis of 180 patients with a clinical diagnosis of respiratory diphtheria admitted from 2011 to 2014 at a tertiary referral hospital. They were evaluated with respect to demographic details, immunization status, clinical features, complications and outcomes.

RESULTS

Most common age group affected was children less than 5 years of age (87 cases, 48.33%). The peak incidence of diphtheria was seen in the months of September and October (111 cases, 62%). Majority of the patients were unimmunized (54%), followed by partially immunized (21%). The most common complication was respiratory in 80 cases (44%), followed by cardiac complications in 54 cases (30%), and renal (16%) and neurological complications (10%). Cardiac complications were associated with the highest mortality rate (63%). The presence of bull neck and pseudomembrane score >2 was associated with a high mortality.

CONCLUSION

Diphtheria is still a preventable public health problem in many developing countries. Improved vaccination coverage, including booster dosage, coupled with early detection and effective treatment, may all reduce incidence and mortality.

New ethnomedicinal claims from Gujjar and Bakerwals tribes of Rajouri and Poonch districts of Jammu and Kashmir, India

BACKGROUND

Medicinal plants are frequently employed by Gujjar and Bakerwal tribes in Rajouri and Poonch districts of Jammu and Kashmir, India for treatment of various ailments in humans and livestock. Hence, extensive field work was conducted to document the ethnomedicinal plants used by these tribes.

METHODOLOGY

Ninety one key informants were interviewed using both in situ and ex situ type of survey methods. The data were analyzed using user value (UV), informant consensus factor (Fic), fidelity level (FL) and relative frequency of citation (Rfc).

RESULTS

A total of 104 species of medicinal plants used in the treatment of 40 different non-communicable ailments with 138 remedies are reported. Cephalanthera longifolia (L.) Fritsch was recorded for the first time with ethnomedicinal uses and the rest of the species were previously reported with different medicinal uses by other tribal people. Out of 138 remedies, 129 were employed for human ailments and the remaining seven were used to treat livestock. Most of the species were harvested for leaves (24 species). Herbs (66 species) were the major life form used for medicinal purpose and the most common method of remedy preparation was decoction/tea (27.8%). The highest use value plant was Verbascum thapsus L. for the treatment of stomachache and snake bite.

CONCLUSIONS

Plants such as Allium humile Kunth, Angelica glauca Edgew, Arnebia benthamii (Wall. ex G. Don) I.M.Johnst, Asparagus racemosus Willd., Balanophora involucrata Hook. f. & Thomson, C. longifolia (L.) Fritsch, Cuscuta epithymum (L.) L., Geranium wallichianum D. Don ex Sweet, Gloriosa superb L., Habenaria intermedia D. Don, Phyllanthus emblica L., Ramaria Formosa (Pers.) Quel. and V. thapsus L. showing high Rfc and FL values may be studied for associated pharmacological activities.

Assessing the impact of irrigation treatments on thiram residual trends: correspondence with numerical modelling and field-scale experiments

The present study was undertaken to study the trends of transport of thiram, a dithiocarbamate pesticide, at different time and depth in the fields under real field conditions for wheat crop. Numerical simulations were carried out by solving the coupled soil-water content movement and mass transport equations using HYDRUS- 1D. The supplementary data used for paramaterization of HYDRUS-1D comprise of irrigation treatments, climatic conditions, and soil characteristics. Results focus on the effects and influence of irrigation treatments on pesticide persistence and mobility. Modelling results were in good agreement with the experimentally determined thiram concentrations. Application of the model to measured field data of thiram movement indicates that the modelling approach can provide reliable and useful estimates of the mass flux of water and non-volatile pesticide in vadose zone. For policy-makers and planners, some regulation strategies are suggested for controlling inappropriate pesticide application under deficit irrigation or rain-fed conditions.

Catalytic regeneration of mercury sorbents

Traditionally, mercury sorbents are disposed of in landfills, which may lead to contamination of soil and groundwater. In this work, the regeneration of activated carbon (AC) as a mercury sorbent was investigated. The decomposition of HgCl2 on the surface of pure AC was studied, as well as sorbent which has been treated with FeCl3 or NaCl. In all cases, the sorbent is found to be structurally stable through a single regeneration, which is verified through BET, XRD, and XPS analysis. The desorption of mercury from the sorbent is found to follow Henry's law. Additionally, a kinetic analysis suggests that although the presence of activated carbon lowers the energy requirement for the desorption of mercury, it significantly decreases the rate by decreasing the concentration of the HgCl2. FeCl3 and NaCl both promoted the decomposition of HgCl2, but FeCl3 did so more significantly, increasing the rate constants by a factor of 10 and decreasing the activation energy for the decomposition of HgCl2 by 14% to 40%.

Auto-immune pancreatitis--an uncommon type of chronic pancreatitis

Auto-immune pancreatitis is an increasingly recognised disorder of presumed auto-immune aetiology. It has to be differentiated from other forms of chronic pancreatitis and pancreatic cancer as it has dramatic response with steroid therapy. So, early and prompt diagnosis of this disorder in early stage of disease is essential. Here a case of auto-immune pancreatitis in a 16 years old young male is reported.

Complete nucleotide sequence of cherry virus A (CVA) infecting sweet cherry in India

Cherry virus A (CVA) is a graft-transmissible member of the genus Capillovirus that infects different stone fruits. Sweet cherry (Prunus avium L; family Rosaceae) is an important deciduous temperate fruit crop in the Western Himalayan region of India. In order to determine the health status of cherry plantations and the incidence of the virus in India, cherry orchards in the states of Jammu and Kashmir (J&K) and Himachal Pradesh (H.P.) were surveyed during the months of May and September 2009. The incidence of CVA was found to be 28 and 13% from J&K and H.P., respectively, by RT-PCR. In order to characterize the virus at the molecular level, the complete genome was amplified by RT-PCR using specific primers. The amplicon of about 7.4 kb was sequenced and was found to be 7,379 bp long, with sequence specificity to CVA. The genome organization was similar to that of isolates characterized earlier, coding for two ORFs, in which ORF 2 is nested in ORF1. The complete sequence was 81 and 84% similar to that of the type isolate at the nucleotide and amino acid level, respectively, with 5' and 3' UTRs of 54 and 299 nucleotides, respectively. This is the first report of the complete nucleotide sequence of cherry virus A infecting sweet cherry in India.

Kinetics of acid base catalyzed transesterification of Jatropha curcas oil

Out of various non-edible oil resources, Jatropha curcas oil (JCO) is considered as future feedstock for biodiesel production in India. Limited work is reported on the kinetics of transesterification of high free fatty acids containing oil. The present study reports the results of kinetic study of two-step acid base catalyzed transesterification process carried out at an optimum temperature of 65 °C and 50 °C for esterification and transesterification respectively under the optimum methanol to oil ratio of 3:7 (v/v), catalyst concentration 1% (w/w) for H₂SO₄ and NaOH. The yield of methyl ester (ME) has been used to study the effect of different parameters. The results indicate that both esterification and transesterification reaction are of first order with reaction rate constant of 0.0031 min⁻¹ and 0.008 min⁻¹ respectively. The maximum yield of 21.2% of ME during esterification and 90.1% from transesterification of pretreated JCO has been obtained.

Cognitive behavior therapy for stuttering: a case series

The present investigation was aimed at studying the efficacy of cognitive behavior therapy (CBT) in reducing the symptoms of stuttering and dysfunctional cognitions and in enhancing assertiveness and quality of life in clients with stuttering. Five clients with stuttering who met the inclusion criteria (male clients with diagnosis of stuttering) and exclusion criteria (clients with brian damage), substance abuse or mental retardation were enrolled for the study. A single-case design was adopted. The pre-, mid- and post-assessment were carried out using Stuttering Severity Scale (SSI), Perception of Stuttering Inventory (PSI), Beck's Anxiety Inventory (BAI), Dysfunctional Attitude (DAS), Fear of Negative Evaluation (FNE), Assertiveness Scale (AS), Rosenberg's Self-Esteem Scale (RSES), and World Health Organization - Quality of Life Scale (WHO-QOL). Five clients received cognitive behavioral intervention comprising of psycho-education, relaxation, deep breathing, humming, prolongation, cognitive restructuring, problem-solving strategies and assertiveness. At post-treatment assessment, there was improvement. The findings of the study are discussed in the light of available research work, implications, limitations of the study and suggestions for future research.

An assessment of institutional deliveries under JSY at different levels of health care in Jaipur District, Rajasthan

BACKGROUND & OBJECTIVE

Janani Suraksha Yojana (JSY) has been implemented in the country to enhance institutional deliveries. This study assess the gaps in delivery services and utilization of resources at Basic and Comprehensive Emergency Obstetric Care Centers (BEmOCs, & CEmOCs), accredited sub centers and private hospitals in district Jaipur, Rajasthan.

METHODS

The study was undertaken during October-December 2008 in 31 selected health facilities (5 CEmOCs, 4 BEmOCs, 14 accredited subcentres and 8 accredited private hospitals) in district Jaipur. Both primary and secondary data was collected using qualitative and quantitative techniques, by facility survey, interview of service providers (specialists, medical officers, and paramedical staff) and beneficiaries.

RESULTS

There is an increase in institutional deliveries following implementation of JSY. Though the normal deliveries were conducted 24 hours by the BEmOCs and CEmOCs however the necessary drugs like parental antibiotics, mesoprostol, magsulf etc were in short supply and use of partograph was absent at the health facilities. The quality of emergency obstetric care services was still poor due to the lack of blood storage units and anesthetists in CEmOCs. Private accredited hospitals fared better as they had the manpower and managed more complicated cases as compared to government facilities, for caesarean sections. The accredited sub centers were nonfunctional negating the very objective of accreditation. Community is still unaware of the 24 hour stay post delivery and provision of grievance redressal system.

CONCLUSION

The quality aspects of institutional deliveries are far from desired level mostly because of lack of resources, both manpower and materials; non achievement of IPHS standards etc. The service quality related to antenatal, intranatal and postnatal care need to be improved. The JSY is perceived as an effective scheme by the beneficiaries but gaps in resources and lack of quality of services needs to be adequately dealt with.

Benign tumors of the larynx: a clinical study of 50 cases

OBJECTIVE

The study was undertaken to identify the common type of lesions, and the age, sex distribution, symptomatology, sites of involvement and prognosis of the same.

STUDY DESIGN

A two-year prospective study was conducted from January 2005 to December 2006.

SETTING

The study was conducted at SMS Medical College, Jaipur, Rajasthan, India-a tertiary referral hospital.

PATIENTS

A total of 50 patients with benign laryngeal lesions were included in the study based on symptoms such as hoarseness of voice, foreign body sensation, throat pain, neck mass and cough and with positive clinical findings on indirect laryngoscopy and neck examination. The patients were in the age group of 14-63 years. All nonoperative cases and malignant cases were excluded. Diagnostic hematological and radiological investigations and therapeutic microlarygoscopic procedures were employed.

RESULTS

A male preponderance with a male:female ratio of 2.5:1 was observed. Majority of the patients were in the age group of 21-30 years. Vocal cord polyps were observed to be the commonest type of lesions. In our study, hoarseness of voice, cough, foreign body sensation and throat pain were found to be the commonest symptoms. Out of the 50 patients in the study group, only 6% patients got complete relief with voice rest and vocal rehabilitation; 94% patients required surgery, which included microlarygoscopy and endolaryngeal surgery. There was no recurrence in cases of vocal polyps and nodules during the period of observation.

CONCLUSION

Microlaryngeal surgery and voice rest offer a cost-effective, useful and safe method for the management of benign laryngeal lesions. With the inclusion of lasers, they can be more precisely operated. As such, the standard treatment of choice in all types of benign tumors of the larynx should consist of a triad of approach by microlaryngeal surgery (either microscopic or endoscopic, with or without use of lasers), voice rest and vocal rehabilitation.

Body mass index and per capita income influence duodenal ulcer healing and H. pylori eradication whilst dietary factors play no part

BACKGROUND

The role of dietary and sociodemographic factors in the healing of duodenal ulcer following H. pylori eradication remains undefined.

AIM

To assess the role of diet, sociodemography and body mass index in the healing of duodenal ulcer and eradication of H. pylori.

METHODS

A cross-sectional study consisting of 67 consecutive duodenal ulcer patients was undertaken. Sociodemographic factors studied included age, sex, occupation, educational status, religion, type of family, number of family members, per capita income and residence (urban vs. rural). Personal habits studied included alcohol consumption and smoking. Regular dietary intake over a two-month period was assessed using the food frequency questionnaire. All patients had documented H. pylori infection at the time of inclusion and received standard triple eradication therapy. Follow-up endoscopy and testing for H. pylori were done 4 weeks after completion of eradication therapy.

RESULTS

The mean age of the 67 patients (60 male, 7 female) was 39.9+/-13.6 years. Healing of duodenal ulcer was documented in 51 patients. H. pylori infection was successfully eradicated in 31 patients but not in the other 36. There was no difference between the groups (Group A1: H. pylori eradicated, Group B1: H. pylori not eradicated) with regard to dietary and socio-demographic variables, except for BMI, which was significantly higher in patients in whom H. pylori had been eradicated. Per capita income was significantly higher in Group A2 (healed duodenal ulcer) as compared to Group B2 (duodenal ulcer not healed) while there was no difference in dietary and socio-demographic variables in these two groups.

CONCLUSION

We found that higher body mass index and higher per capita income were associated with successful H. pylori eradication and duodenal ulcer healing, respectively, and that diet had no role to play in either. Further epidemiological studies from different parts of India and studies that control for Helicobacter pylori are required to establish predictive factors.

Randomized, single-blind, placebo-controlled multicenter trial to compare the efficacy and safety of metronidazole and satranidazole in patients with amebic liver abscess

The aims of our randomized, single-blind trial involving 49 patients were to study the efficacy, side effects, and tolerance of metronidazole and satranidazole in patients of amebic liver abscess. Twenty-five patients received metronidazole (800 mg TID) and 24 received satranidazole (300 mg TID with placebo at mealtime). Patients recorded side effects and tolerability through a performa. The time taken for resolution of fever and pain and the fall in abscess size was not significant. However, tolerance of satranidazole as reported by the patients was significantly better than metronidazole (P < .005). The incidence of adverse effects was significantly lower in the group given satranidazole (P < .005). The incidence of nausea and metallic taste was significantly lower in the patients given satranidazole (P < .005). Thus, despite having a similar efficacy, satranidazole showed a far lower incidence of side effects and had a significantly better tolerance than Metronidazole.

Cyst vallecula unusual presentation

Laryngeal cysts, particularly cyst vallecula are generally benign lesions which cause mild dysphagia or change in voice. We report here a case of cyst vallecula that caused soreness of throat, dysphagia and change in voice. A 22-year male presented with progressive dysphagia and muffled voice secondary to a large cystic mass involving entire vallecula and during coughing presented in oral cavity. Per oral marsupilization done and the problem resolved.

Children have unique set of predisposing factors which have been highlighted. Expected microbiology and setting for unusual organisms are mentioned. Clinical presentations', including importance of location and number of abscesses has been discussed. Role of each modality of treatment clarified. Importance and limitations of investigations and imaging explained and complications and mortality discussed.

Detection of Entamoeba histolytica using polymerase chain reaction in pus samples from amebic liver abscess

BACKGROUND AND OBJECTIVE

Direct demonstration of Entamoeba histolytica by conventional microscopy and in vitro culture in pus obtained from amebic liver abscess (ALA) is often unsuccessful. We evaluated polymerase chain reaction (PCR) for detection of E. histolytica DNA in such pus.

METHODS

Species-specific primers were used for the amplification of E. histolytica DNA from liver pus obtained from 30 patients with ALA. Patients with pyogenic liver abscess and sterile (autoclaved) pus spiked with Entamoeba dispar and bacteria (Escherichia coli, Klebsiella spp. and Bacteroides spp.) were used as negative controls.

RESULTS

PCR was positive in 83% of pus specimens from patients with ALA, and was negative in all 25 pus specimens obtained from pyogenic abscess and autoclaved pus spiked with known bacteria. Sensitivity and specificity of PCR were 83% and 100%, respectively. The overall positivity of PCR was higher compared to serological tests.

CONCLUSION

PCR may be a more reliable and better alternative diagnostic modality for ALA.

Comparison of efficacy of pantoprazole alone versus pantoprazole plus mosapride in therapy of gastroesophageal reflux disease: a randomized trial

The present study aimed to compare the efficacy for the therapy of GERD of pantoprazole alone with a combination of pantoprazole and mosapride. The study was a prospective, randomized trial involving 68 patients suffering heartburn and/or regurgitation at least twice a week for 6 weeks. Sixty-one patients consented to be randomized to receive either pantoprazole 40 mg b.i.d. (n = 33, group A) or pantoprazole 40 mg b.i.d. plus mosapride 5 mg t.d.s. (n = 28, group B) for 8 weeks. Twenty-four-hour esophageal pH-metry and endoscopy were conducted at recruitment and endoscopy was repeated at 8 weeks in all the patients studied. There were no differences in symptomatic responses to therapy between the groups (69.7% vs 89.2%; P = 0.11). The mean symptom score after 8 weeks was significantly lower in group B (3.78 +/- 3.62 vs 1.67 +/- 2.09; P = 0.009). Nonerosive esophagitis was present in 29 patients. In patients with nonerosive GERD there was no significant difference in symptomatic response to either regimen (17/20 in group A and 7/9 in group B responded; P = 0.63). In erosive esophagitis, symptomatic responses occurred more frequently in group B, 18/19 (94.7%), than in group A, 6/13 (46.2%; P = 0.003). However endoscopic healing of esophagitis occurred equally with either regimen (6/11, 54.5% in group A; 12/17, 70.5% in group B; P = 0.44). In nonerosive GERD, the addition of mosapride offers no benefit over pantoprazole alone. A combination of pantoprazole and mosapride is more effective than pantoprazole alone in providing symptomatic relief to patients with erosive GERD.

Abdominal tuberculosis

Tuberculosis can involve any part of the gastrointestinal tract and is the sixth most frequent site of extrapulmonary involvement. Both the incidence and severity of abdominal tuberculosis are expected to increase with increasing incidence of HIV infection. Tuberculosis bacteria reach the gastrointestinal tract via haematogenous spread, ingestion of infected sputum, or direct spread from infected contiguous lymph nodes and fallopian tubes. The gross pathology is characterized by transverse ulcers, fibrosis, thickening and stricturing of the bowel wall, enlarged and matted mesenteric lymph nodes, omental thickening, and peritoneal tubercles. Peritoneal tuberculosis occurs in three forms : wet type with ascitis, dry type with adhesions, and fibrotic type with omental thickening and loculated ascites. The most common site of involvement of the gastrointestinal tuberculosis is the ileocaecal region. Ileocaecal and small bowel tuberculosis presents with a palpable mass in the right lower quadrant and/or complications of obstruction, perforation or malabsorption especially in the presence of stricture. Rare clinical presentations include dysphagia, odynophagia and a mid oesophageal ulcer due to oesophageal tuberculosis, dyspepsia and gastric outlet obstruction due to gastroduodenal tuberculosis, lower abdominal pain and haematochezia due to colonic tuberculosis, and annular rectal stricture and multiple perianal fistulae due to rectal and anal involvement. Chest X-rays show evidence of concomitant pulmonary lesions in less than 25 per cent of cases. Useful modalities for investigating a suspected case include small bowel barium meal, barium enema, ultrasonography, computed tomographic scan and colonoscopy. Ascitic fluid examination reveals straw coloured fluid with high protein, serum ascitis albumin gradient less than 1.1 g/dl, predominantly lymphocytic cells, and adenosine deaminase levels above 36 U/l. Laparoscopy is a very useful investigation in doubtful cases. Management is with conventional antitubercular therapy for at least 6 months. The recommended surgical procedures today are conservative and a period of preoperative drug therapy is controversial.

A randomized trial of oral refeeding compared with jejunal tube refeeding in acute pancreatitis

BACKGROUND

Relapse of pain during refeeding in acute pancreatitis may have a relation to the route of refeeding.

AIM

To compare the efficacy of oral refeeding with jejunal tube refeeding in patients with acute pancreatitis, and determine the frequency of refeeding pain and factors associated with it.

METHODS

Consecutive patients with acute pancreatitis, severe enough to stop oral feeding for 48 hours, were randomized to receive either oral or jejunal tube refeeding. The feeds were similar in calorie, lipid and protein content (400 Kcal on day 1, 1000 Kcal on day 2, 1400 Kcal on day 3, 1500 Kcal on day 4, and 1700 Kcal on day 5). Clinical and biological factors (serum amylase, lipase, C-reactive protein) and Balthazar CT severity index were recorded. Frequency of pain relapse and factors associated with it were analyzed.

RESULTS

28 patients with acute pancreatitis (biliary 14, alcohol 9, idiopathic 3, post-ERCP 2) were included. Fifteen patients received oral and 13 received enteral tube refeeding. Four patients in the oral group and none in the enteral tube group had relapse of pain (p=0.06). The factors associated with refeeding pain were longer duration of initial pain (p<0.02) and higher CT severity index (p<0.02). Pain relapse increased the total hospital stay (p<0.004) and hospital stay after the first attempt at feeding (p<0.001).

CONCLUSIONS

Jejunal tube refeeding may reduce the frequency of pain relapse as compared to oral refeeding although the difference was not significant in this study. Longer duration of pain and higher CT severity index score were associated with occurrence of refeeding pain.

Yogic versus conventional treatment in diarrhea-predominant irritable bowel syndrome: a randomized control study

This study was conducted to evaluate the comparative effect of yogic and conventional treatment in diarrhea-predominant irritable bowel syndrome (IBS) in a randomized control design. The patients were 22 males, aged 20-50 years, with confirmed diagnosis of diarrhea-predominant IBS. The conventional group (n = 12, 1 dropout) was given symptomatic treatment with loperamide 2-6 mg/day for 2 months, and the yogic intervention group (n = 9) consisted of a set of 12 asanas (yogic poses, i.e., Vajrasana, Shashankasana, Ushtrasana, Marjariasana, Padhastasana, Dhanurasana, Trikonasana in two variations, Pawanmuktasana, and Paschimottanasana) along with Surya Nadi pranayama (right-nostril breathing) two times a day for 2 months. All participants were tested at three regular intervals, at the start of study--0 month, 1 month, and 2 months of receiving the intervention--and were investigated for bowel symptoms, autonomic symptoms, autonomic reactivity (battery of five standard tests), surface electrogastrography, anxiety profile by Spielberger's Self Evaluation Questionnaire, which evaluated trait and state anxiety. Two months of both conventional and yogic intervention showed a significant decrease of bowel symptoms and state anxiety. This was accompanied by an increase in electrophysiologically recorded gastric activity in the conventional intervention group and enhanced parasympathetic reactivity, as measured by heart rate parameters, in yogic intervention group. The study indicates a beneficial effect of yogic intervention over conventional treatment in diarrhea-predominant IBS.

Geographical difference in antimicrobial resistance pattern of Helicobacter pylori clinical isolates from Indian patients: Multicentric study

AIM

To assess the pattern of antimicrobial resistance of Helicobacter pylori isolates from peptic ulcer disease patients of Chandigarh, Delhi, Lucknow, Hyderabad and Chennai in India, and to recommend an updated anti-H. pylori treatment regimen to be used in these areas.

METHODS

Two hundred and fifty-nine H. pylori isolates from patients with peptic ulcer disease reporting for clinical management to the Post Graduate Institute of Medical Education and Research, Chandigarh; All India Institute of Medical Sciences, New Delhi; Sanjay Gandhi Post Graduate Institute of Medical Sciences, Lucknow; Deccan College of Medical Sciences and Allied Hospitals, Hyderabad; and hospitals in Chennai in collaboration with the Dr ALM Post Graduate Institute of Basic Medical Sciences were analyzed for their levels of antibiotic susceptibility to metronidazole, clarithromycin, amoxycillin, ciprofloxacin and tetracycline. The Epsilometer test (E-test), a quantitative disc diffusion antibiotic susceptibility testing method, was adopted in all the centers. The pattern of single and multiple resistance at the respective centers and at the national level were analyzed.

RESULTS

Overall H. pylori resistance rate was 77.9% to metronidazole, 44.7% to clarithromycin and 32.8% to amoxycillin. Multiple resistance was seen in 112/259 isolates (43.2%) and these were two/three and four drug resistance pattern to metronidazole, clarithromycin, amoxycillin observed (13.2, 32 and 2.56%, respectively). Metronidazole resistance was high in Lucknow, Chennai and Hyderabad (68, 88.2 and 100%, respectively) and moderate in Delhi (37.5%) and Chandigarh (38.2%). Ciprofloxacin and tetracycline resistance was the least, ranging from 1.0 to 4%.

CONCLUSION

In the Indian population, the prevalence of resistance of H. pylori is very high to metronidazole, moderate to clarithromycin and amoxycillin and low to ciprofloxacin and tetracycline. The rate of resistance was higher in southern India than in northern India. The E-test emerges as a reliable quantitative antibiotic susceptibility test. A change in antibiotic policy to provide scope for rotation of antibiotics in the treatment of H. pylori in India is a public health emergency.

Laparoscopic Nissen fundoplication; results of a prospective pilot study

Laparoscopic fundoplication is rapidly becoming the surgical procedure of choice in western countries for the management of gastro-oesophageal reflux disease (GERD). Experience with this technique is limited in India. Most operations continue to be performed through the traditional open technique, thus denying the advantage of a minimal invasive approach to patients. This study was done to evaluate the feasibility and short term results of laparoscopic Nissen fundoplication. Between June 2000 and March 2002, a total of 10 patients with GERD refractory to medical therapy or requiring daily treatment underwent laparoscopic Nissen fundoplication. Preoperative evaluation included scoring of symptoms, oesophagogastroduodenoscopy, barium swallow and nuclear scan. The intraoperative and post-operative course of the patients was recorded. At 3 months post-surgery, patients were re-evaluated using pre-operative symptom scores and investigations to assess the benefit of and complications associated with surgery. Laparoscopic nissen fundoplication was successfully completed in all the patients. Follow up ranged from 3 to 18 months with a mean of 5.9 months. The mean symptom score decreased from 10.1 pre-operatively to 1.7 (p value < 0.001). Eight out of 9 patients (88%) had endoscopic resolution of oesophagitis. Seven patients (70%) were off medication following surgery while the remaining 3 (30%) were taking medication intermittently. Overall, 80% of the patients were satisfied with the surgery. One patient required re-exploration due to bleeding from a short gastric vessel. The most frequent post-operative complication was temporary dysphagia in 60% of patients, which improved with conservative management over 2 to 3 weeks. We concluded that laparoscopic Nissen fundoplication is a safe and effective procedure to treat patients with GERD.
