ABSTRACT
Abstract To evaluate the antibiotic susceptibility patterns in URTIs reporting to tertiary hospitals of Lahore. A cross-sectional study employing 259 culture sensitivity reports obtained from tertiary care hospitals of Lahore. Using SPSS, descriptive statistics were used to estimate frequencies and percentages. In URTIs, S. aureus (5%) was the frequent gram-positive isolate followed by MRSA (1.5%) and MSSA (1.5%), while P. aeruginosa (15.8%) was the prevalent gram-negative isolate followed by Klebsiella (13.1%) and E. coli (6.9%). Against P. aeruginosa, ceftazidime (7.7%), cefuroxime/ceftriaxone (4.6%), amoxicillin (4.3%) and ciprofloxacin (4.2%), were tested resistant, while imipenem (11.2%), ciprofloxacin (9.2%), amikacin (9.2%), meropenem/ levofloxacin/gentamicin (8.1%) and piptaz (6.9%) were found sensitive. Against Klebsiella, carbepenems (7.3%), amikacin (6.5%), ciprofloxacin (5.4%) and gentamicin (5%) were tested sensitive, whereas, ceftazidime (8.5%), ceftriaxone (5.8%), cefaclor (5.5%), ampicillin (4.6%), co-amoxiclave (4.2%) and ciftazidime/ciprofloxacin (3.8%) were found resistant. Overall, imipenem (35%), meropenem (30.8%) and amikacin (31.9%) were the three most sensitive antibiotics, while ceftazidime (25.4%), ceftriaxone (19.2%) and ampicillin (18.5%) were the three most resistant antibiotics. Data suggested that P.aeruginosa and Klebsiella, were the most frequent bacterial isolates in URTIs of Lahore. These isolates were resistant to ampicillin, cefuroxime and ceftazidime, but were sensitive to carbapenem and aminoglycosides

The study was performed to estimate the association of hypertension and dyslipidaemia with increasing body weight and obesity in Type II diabetics of Lahore, Pakistan. An observational study was conducted by enrolling 2708 obese diabetics from four diabetes care centres of Lahore, Pakistan. Data was collected for a period of 7 months. Associations were estimated using chi-square, binary and multinomial logistic regression. Data suggested that blood pressure, systolic and diastolic, exhibited continual increase with increasing body weight and obesity class in diabetes patients with 41.8% increase in the prevalence of hypertension in obesity class III subjects (OR; 1.91, p=0.02). Likewise, triglycerides and total cholesterol exhibited continual increase in their mean values with increasing obesity, i-e., an overall increase in the prevalence of dyslipidaemia of 27.2% in obesity class 3 subjects (OR; 1.94, p=0.29). Taken together, this data suggested that hypertension is potentially associated with increasing obesity in diabetics, while dyslipidaemia demonstrated plausible association only with obesity class 3.

ABSTRACT The leaves of Acacia modesta Wall. have been shown to possess diverse pharmacological properties. Therefore, we aimed at evaluating anti-diabetic, cytotoxic and proliferative effects of extracts of Acacia modesta Wall. leaves. After evaluating the primary and secondary metabolites, anti-diabetic activity of various extracts was assessed by α-amylase inhibition, glucose uptake by yeast cells and non-enzymatic glycosylation of hemoglobin assay. Cytotoxicity and proliferative potential was assessed by MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) and short term proliferation assays, respectively, using human liver carcinoma cell line, HepG2. Among other extracts, chloroform extract exhibited 34.16% inhibition of α-amylase, 90.65% inhibition of hemoglobin glycosylation and 94.75% glucose uptake employing α-amylase inhibition, non-enzymatic glycosylation of hemoglobin and glucose uptake by yeast cells assays, respectively. Moreover, extracts exhibited no significant effects on HepG2 cell viability and proliferation. So, this data suggested that chloroform extract of leaves of Acacia modesta Wall., exhibited higher anti-hyperglycemic activity in comparison to extracts in other solvents, while no extract demonstrated cytotoxic and proliferation effects when tested using HepG2 cell line

<p><b>OBJECTIVE</b>Helicobacter pylori is a Gram-negative organism. Its outer membrane protein Q (HopQ) mediates host-pathogen interactions; HopQ genotypes 1 and 2 are found associating with gastroduodenal pathologies. The authors measured the anti-adhesion effects of the extracts of Abelmoschus esculentus, Zingiber officinale, Trachyspermum ammi, Glycyrrhiza glabra, Curcuma longa and Capsicum annum against HopQ genotypes and H. pylori cytotoxin-associated gene A (CagA).</p><p><b>METHODS</b>DNA was extracted by polymerase chain reaction of the HopQ genotypes (i.e., type 1, type 2 and CagA) from 115 H. pylori strains. The effect of the extracts from selected dietary ingredients was determined using a gastric adenocarcinoma cell line and a quantitative DNA fragmentation assay. The anti-adhesive effect of these extracts on H. pylori was tested using an anti-adhesion analysis.</p><p><b>RESULTS</b>C. annum, C. longa and A. esculentus showed prominent anti-adhesion effects with resultant values of 17.3% ± 2.9%, 14.6% ± 3.7%, 13.8% ± 3.6%, respectively, against HopQ type 1 and 13.1% ± 1.7%, 12.1% ± 2%, 11.1% ± 1.6%, respectively, against HopQ type 2. C. longa (93%), C. annum (89%) and A. esculentus (75%) had better anti-adhesive activity against H. pylori with HopQ type 1 compared to HopQ type 2 with respective values of 70%, 64% and 51%. Extracts of C. annum (14.7% ± 4.1%), A. esculentus (12.3% ± 4.1%) and Z. officinale (8.4% ± 2.8%) had an anti-adhesion effect against CagA-positive H. pylori strains compared to CagA-negative strains.</p><p><b>CONCLUSION</b>The anti-adhesion properties of the tested phytotherapeutic dietary ingredients were varied with HopQ genotypes. HopQ type 1 was found to be more sensitive to extracts of C. annum, C. longa and A. esculentus compared to the HopQ type 2 genotype.</p>
ABSTRACT
Objective: To determine the clinical characteristics of Budd-Chiari syndrome [BCS], its causes and outcome at a tertiary care hospital
Study Design: An observational study
Place and Duration of Study: The Aga Khan University Hospital, Karachi, from 2004 to 2014
Methodology: A retrospective analysis of data was conducted. A predesigned questionnaire was filled from medical records of patients with BCS. Clinical features, etiology, management and outcome was noted from 2004 to 2014. Descriptive statistics were determined
Results: Forty-five patients' charts were reviewed; 26 [57.8%] were male patients. The median [IQR] age at diagnosis was 26.0 [20.5 to 34.5] years. Primary BCS was seen in 27 [60.0%] patients. The most frequent clinical features included ascites [82.2%], abdominal pain [55.6%], and hepatomegaly [31.1%]. A combined hepatic vein/inferior vena cava block was found in 25 [55.6%] patients. Out of the 28 tested patients protein C and protein S deficiencies were detected in 22 [78.6%] and 17 [60.7%] patients, respectively. Antithrombin III deficiency was detected in 14 [58.3%] of those tested patients. Anticoagulants were used in 24 [53.3%] patients. TIPS was done in 11 [24.4%] patients. Mortality was 6.7% [n=3]
Conclusion: Congenital thrombophilia was a major causal factor. Age, clinical features, biochemistry and management are important factors in survival
ABSTRACT
Primary Hepatic Carcinoid Tumor [PHCT] represents an extremely rare clinical entity with only a few cases reported to date. These tumors are rarely associated with metastasis and surgical resection is usually curative. Herein, we report two cases of PHCT associated with poor outcomes due to late diagnosis. Both cases presented late with non-specific symptoms. One patient presented after a 2-week history of symptoms and the second case had a longstanding two years symptomatic interval during which he remained undiagnosed and not properly worked up. Both these cases were diagnosed with hepatic carcinoid tumor, which originates from neuroendocrine cells. Case 1 opted for palliative care and expired in one month's time. Surgical resection was advised to the second case, but he left against medical advice

To evaluate the Age of patients and the site of Colonic Neoplastic Lesions [CNL] and to determine the appropriate screening strategy for Colorectal Carcinoma [CRC] [sigmoidoscopy versus colonoscopy] in our population. This is a cross sectional study. Data of all patients more than 16 years of age who underwent full colonoscopic examination at the Aga Khan University hospital between January 2011 till December 2013 and were diagnosed to have CRC or advanced adenomas [defined as polyp more than 1 cm and/or having villous morphology on histology] was recorded. Lesions found distal to the splenic flexure were characterized as distal lesions and while lesions found between the splenic flexure and the cecum were characterized as proximal lesions. During the study period colonic neoplastic lesions were found in 217 patients; 186 [85.7%] patients had CRC and 31 [14.3%] patients had advanced adenomatous polyps. Mean age was 55.8 +/- 14 years and amongst them 72 [33.2%] patients were less than 50 years of age while 145 [66.8%] were more than 50 years. In 144 [66.4%] patients lesions were located in the distal colon, 65 [30%] had lesions in the proximal colon while in 8 [3.7%] patients the neoplastic lesions were found both in the proximal and distal colon. The predominant symptoms were bleeding per rectum in 39.6% of patients followed by weight loss in 31.8% of patients. Only 3 patients had familial syndromes with multiple polyps. When patients younger than 50 years of age were compared with patients more than 50 years there was no statistically significant difference between the site of neoplastic lesion as well as the presenting symptoms. [p value 0.85]. Colonic Neoplastic Lesions presented at younger age in our study population and one third of the lesions were found in the right sided colon. Hence screening for CNLs should be implied at an earlier age preferably with colonoscopy. More population based data is required to further validate our results

Stem cell research holds a promise to treat and prevent age-related degenerative changes in humans. Literature is replete with studies showing that stem cell function declines with aging, especially in highly proliferative tissues/ organs. Among others, telomerase and telomere damage is one of the intrinsic physical instigators that drive agerelated degenerative changes. In this review we provide brief overview of telomerase-deficient aging affects in diverse stem cells populations. Furthermore, potential disease phenotypes associated with telomerase dysregulation in a specific stem cell population is also discussed in this review. Additionally, the role of telomerase in stem cell driven cancer is also briefly touched upon.
ABSTRACT
The objective of this retrospective study was to evaluate presentation of celiac disease in adults. It included 77 patients, 41 [53.2%] males with median age 26 years and median body mass index of 18 [16 - 22] kg/m[2]. Typical presentation with gastrointestinal symptoms was seen in 76.6%. Atypical presentation with extra intestinal complaints in 7.8% and silent presentation in 15.6%. Major symptoms were diarrhea in 64.9%, weight loss 36.4%, abdominal pain 35.1%, vomiting 32.5%, pallor 24.7%, and weakness 13%. Iron deficiency was documented in 20.8%, B12 deficiency in 9.1%, folic acid deficiency in 6.5% and vitamin D deficiency in 10.4%. Half of the patients had haemoglobin less than 11 g/dl. Osteoporosis and osteomalacia, hypothyroidism, diabetes and atrophic gastritis were seen in 2.6% each. Raised alanine aminotransferase was documented in 23.4%. Duodenal biopsy, done in 39 patients, revealed increased intraepithelial lymphocytes in 11, along with crypt hyperplasia in 3, partial villous atrophy in 15 and sub-total villous atrophy in 10. In conclusion, celiac disease in adults should be looked for in patients with chronic diarrhea or irritable bowel syndrome like symptoms, underweight, anaemic, or having nutritional deficiencies
ABSTRACT
Wilson's disease [WD] is a rare autosomal recessive disorder of copper metabolism. Data regarding WD is not available from Pakistan. A cross-sectional study was conducted at The Aga Khan University Hospital, Karachi, and all patients admitted with primary and secondary diagnosis of Wilson's disease were added. A total of 47 patients were seen; 68% [n = 32] were male. The mean age was 26.6 +/- 9.97 years. Most of the patients presented with hepatic, [n = 22, 46.8%], neurological, [n = 17, 36.2%] and psychiatric [n = 8, 17%] symptoms. Mean ceruloplasmin level was 0.17 +/- 0.13 g/dl; it was < 0.25 g/dl in 39 [86.6%] patients. Serum copper [Cu] was reduced in 32 [68.1%] patients and 24-hr-urinary Cu was raised in 22 [47.6%] patients. Slit lamp examination for Kayser-Fleischer [KF] rings was done on 15 [31.9%] patients and 9 [60%] of them had KF rings. Mean serum aspartate transaminase [AST] / alanine transaminases [ALT] ratio was 1.92 and median alkaline phosphatase / total bilirubin ratio was 79.30 [IQR 35.05; 166.50]
ABSTRACT
Objectives: Carcinoma of unknown primary origin [CUP] is heterogeneous group of cancers. Role of gastrointestinal [GI] endoscopy in this entity is under investigated. Aim of this study was to evaluate yield of Colonoscopy and Esophagogastroduodenoscopy [EGD] in localizing primary tumor in patients with CUP
Methodology: Patients with histopathologically proven CUP who underwent colonoscopy / EGD to find the primary tumor from December 2009 to December 2011 were included in the study. Abdominal symptoms and cytokeratin [CK] 7 and 20 markers were correlated with presence of primary in GI tract
Results: After giving informed consent 86 patients were included in final analysis. All patients underwent colonoscopy while 60[70%] got EGD along with colonoscopy. Mean age was 55.10 +/-11.94 years with 52[60%] male. Abdominal symptoms were present in 50%. CK7+/CK20- in 34[40%]; CK7-/CK20+ in 2[2%] while CK7+/20+ in 7[8%] of metastatic tumor samples. Liver was metastatic site in 47[55%], Lymph node 12[14%] and Ascites in 8[9%]. Endoscopy detected primary in 6 [7%] patients with 3 each in stomach and colon. No association of abdominal symptoms and cytokeratin markers was found with presence of GI primary site
Conclusion: Yield of localizing primary lesion in the GI tract by pan-endoscopy was limited. Abdominal symptoms and cytokeratin markers do not predict presence of gastrointestinal malignancies
ABSTRACT
To determine patients perception and knowledge regarding diet in cirrhosis and its relationship with the level of patients education. Cross-sectional observational study. This study was conducted at Gastroenterology Outpatient Clinics at the Aga Khan University Hospital, Karachi, the Aga Khan Health Services, Malir, Karachi and Hamdard University, Karachi, from January to December 2010. Consecutive adult patients with compensated cirrhosis were enrolled. Demographic data, level of education, type and reason of food restriction as well as the source of dietary information was asked. Baseline laboratory test were performed, and nutritional status was assessed by BMI normogram. Ninety patients, 58% male were enrolled. Mean age of the patient was 49 +/- 11 years. Overall 73% of the patients were restricting fat, meat, fish and eggs in their diet; 53% were in uneducated group and 47% were in educated group [CI, 0.24-1.62, p-0.34]. Twenty two patients [62.8%] in uneducated and 21 in educated group [68%] were restricting diet on the advice of their doctors, whereas 13 in uneducated group [37%] and 11 in educated group [32%] believed these dietary components to be harmful for the liver. Thirty two of uneducated patient [71.1%] and 28 of educated patients [62.2%] believed that vegetables, fruits and sugarcane had a beneficial effect on the liver. Main source of dietary information to the patients was the doctor. On sub-group analysis those who restricted diet irrespective of their educational level, had more patients with BMI less than 18.5 kg/m[2], [CI 0.01-0.94, p-0.001], haemoglobin less than 12 g/dl [CI 0- 0.03, p-0.001] and serum albumin less than 3 g/dl [CI 0.1- 03, p-0.001]. Both educated and uneducated classes of the patients have improper knowledge and perception of diet in cirrhosis. Patients with cirrhosis who restricted diet, had relatively low BMI, haemoglobin and albumin as compared to those who did not restrict. Main source of dietary information to cirrhotic patients were health care personnels

Hepatitis D virus [HDV] superinfection in patients with chronic hepatitis B leads to accelerated liver injury, early cirrhosis, and decompensation. It may be speculated that hepatocellular carcinoma [HCC] may differ in these patients from hepatitis B virus [HBV] monoinfection. The aim of this study was to compare clinical aspects of hepatocellular carcinoma in patients of hepatitis D with HBV monoinfection. A total of 92 consecutive HCC cases seropositive for antibody against HDV antigen [HDV group] were compared with 92 HBsAg-positive and anti-HDV-negative cases [HBV group]. The features including sex, body mass index, presence of ascites, serum biochemistry, gross tumor appearance, child class, barcelona cancer liver clinic and okuda stages were not significantly different between the 2 groups. Decreased liver size was noticed more in cases of HDV compared with HBV group where the liver size was normal or increased [P=0.000]. HDV patients had lower platelets [P=0.053] and larger varices on endoscopy [P=0.004]. Multifocal tumors and elevated alpha-fetoprotein level>1000 IU/mL were more common in HBV group [P=0.040 and P=0.061]. TNM classification showed more stage III-IV disease in HBV group [P=0.000]. Decreased liver size and indirect evidence of more severe portal hypertension and earlier TNM stage compared with HBV monoinfection indicate that HDV infection causes HCC in a different way, possibly indirectly by inducing inflammation and cirrhosis
ABSTRACT
Liver biopsy has an important role in staging of fibrosis [SoF] and grading of inflammation [GoI] in chronic hepatitis C [CHC] patients. The effect of size and number of portal tracts [NoP] on grading and staging of liver biopsy was evaluated. A total of 150 consecutive liver biopsy core [LBC] of patients with CHC were obtained. There were 98 [65.3%] males. Mean length of LBC was 1.45 +/- 0.48 cm. Mean number of portal tracts [NoP] was 11 +/- 4.6. Mean length of LBC was greater [1.60 +/- 0.45 cm] in stage 4 [n=41; 27.3%] and lesser [1.28 +/- 0.39] in stage 1 [n=23; 15%, p=0.04]. The mean NoP were 8.5, 10.6 and 13.1 in GoI 1, 2 and 3 respectively [p < 0.001]. The mean NoP were 7.6, 11.1, 11.3 and 14.5 in SoF 1, 2, 3 and 4 respectively [p < 0.0001]. There was a good correlation between number of portal tracts and length of LBC [r[2]=0.56]

To evaluate the efficacy of L-ornithine-L-aspartate [LOLA] as an adjuvant therapy in cirrhotic patients with hepatic encephalopathy [HE]. Randomized placebo controlled study. The Aga Khan University Hospital, Karachi in the year 2003-2004. Patients with HE were randomized to receive LOLA or placebo medicine as an adjuvant to treatment of HE. Number connection test-A [NCT-A], ammonia level, clinical grade of HE and duration of hospitalization were assessed. Out of 120 patients, there were 62 males with mean age of 57 +/- 11 years. Improvement in HE was higher [n=40, 66.7%] in LOLA group as compared to the placebo group [n=28, 46.7%, p=0.027]. In patients with grade I or less encephalopathy, improvement was seen in 6 [35.3%] and 3 [20%] patients in LOLA and placebo groups respectively [p=0.667]. Patients with HE grade II and above showed improvement in 34 [79.1%] and 25 [55.6%] cases in LOLA and placebo group respectively [p=0.019]. On multivariate analysis patients with HE of grade II and above showed prothrombin time, creatinine level and use of LOLA influencing the outcome. Duration of hospitalization was 93.6 +/- 25.7 hours and 135.2 +/- 103.5 hours in LOLA and placebo groups respectively [p=0.025]. No side effects were observed in either groups. In cirrhotic patients with advanced hepatic encephalopathy treatment with LOLA was safe and associated with relatively rapid improvement and shorter hospital stay
ABSTRACT
The symptoms of irritable bowel syndrome resemble those of small intestinal bacterial overgrowth [SIBO]. The aim of this study was to determine the frequency of SIBO and lactose intolerance [LI] occurrence in patients with diarrhea-predominant irritable bowel syndrome [IBS-D] according to Rome III criteria. In this retrospective case-control study, patients over 18 years of age with altered bowel habit, bloating, and patients who had lactose Hydrogen breath test [H2 BT] done were included. The "cases" were defined as patients who fulfill Rome III criteria for IBS-D, while "controls" were those having chronic nonspecific diarrhea [CNSD] who did not fulfill Rome III criteria for IBS-D. Demographic data, predominant bowel habit pattern, concurrent use of medications, etc., were noted. Patients with IBS-D were 119 [51%] with a mean age of 35 +/- 13 years, while those with CNSD were 115 [49%] with mean age 36 +/- 15 years. Patients in both IBS-D and CNSD were comparable in gender, with male 87 [74%] and female 77 [64%]. SIBO was documented by lactose H2 BT in 32/234 [14%] cases. It was positive in 22/119 [19%] cases with IBS-D, while 10/115 [9%] cases had CNSD [P = 0.03]. LI was positive in 43/234 [18%] cases. Of these, 25/119 [21%] cases had IBS-D and 18/115 [16%] cases had CNSD [P = 0.29]. SIBO was seen in a significant number of our patients with IBS-D. There was no significant age or gender difference in patients with or without SIBO
ABSTRACT
To determine precipitants of hepatic encephalopathy [HE] and their impact on hospital stay and mortality. Cross-sectional, analytical study. The Aga Khan University Hospital, from January 2005 to December 2007. Consecutive patients admitted with different grades of HE were evaluated between January 2005 and December 2007. The precipitants of HE were correlated with the different grades of HE, and length of hospital stay and mortality. Chi-square test was used to compare the proportion of precipitating factors versus hospital stay and grade with significance at p < 0.05. Of the 404 patients 252 [62%] were males. Hepatitis C virus was the cause of cirrhosis in 283 [70%]; Child Turcotte Pugh [CTP] class C was present in 317 [78%] patients. On presentation, 17% patients had grade 1 HE while 44%, 29% and 10% had grades 2, 3 and 4 respectively. The most common precipitant of HE was spontaneous bacterial peritonitis in 83 [20.5%], constipation in 74 [18.3%] and urinary tract infection in 62 [15.3%]. One hundred and forty [35%] patients had >/= 2 precipitating factors while no precipitant was noted in 50 [12%] patients. Mean hospital stay was 4 +/- 3 days. The lesser the number of precipitants, shorter was the length of stay [p < 0.01] and lesser was the grade of HE [p=0.025]. Complete reversal of HE was noted in 366 patients [91%] while the remaining had grade 1 HE on discharge. Nine [2.2%] patients died during the hospital stay. No mortality was noted in patients without precipitants. Patients presenting with >/= 2 precipitating factors and advanced grade of HE had a prolonged hospital stay. Moreover, patients without precipitants had better outcomes

To determine the frequency and specific characteristic features of portal hypertensive gastropathy [PHG] in cirrhosis due to viral etiology. Cross-sectional descriptive study. The Aga Khan University Hospital, Karachi, from June 2006 till June 2008. Patients with hepatitis B and C cirrhosis were included who underwent screening esophago-gastro-duodenoscopy [EGD] for varices. Baveno III consensus statement was used for diagnosing PHG on endoscopy and divided them into two subgroups i.e. mild and severe. Data related to platelet/spleen ratio, MELD score and Child Turcotte Pugh [CTP] score indicating severity of cirrhosis were recorded in all patients. Findings were compared by using independent sample t-test. Out of 360 patients who underwent screening EGD, 226 [62.8%] were males. Two hundred and eighty one [78%] had hepatitis C while 79 [22%] suffered from hepatitis B related cirrhosis. Three hundred patients [83.3%] had PHG while 71 [24%] had severe PHG. Higher proportion of esophageal varices [89.7%] was present among those who had PHG [p < 0.001]. On univariate analysis lower platelet counts [117 +/- 55 vs. 167 +/- 90; p < 0.001], increased spleen size [14.1 +/- 2.9 cm vs. 12 +/- 2.4cm; p < 0.001] were found in PHG patients as compared to those without it. Similarly, lower platelet/spleen ratio was noted in patients with severe PHG [916 +/- 400 vs. 1477 +/- 899; p < 0.001]. Furthermore, on multivariate analysis CTP score > 8 MELD score > 12 and platelets/spleen ratio < 900 were significantly associated factors with severe PHG. Frequency of PHG was 83% while severe PHG was seen in 24% cases of viral hepatic cirrhosis. MELD score > 12, CTP score >/= 8 and platelets/spleen ratio = 900 were significant factors of severe PHG

To assess the quality of gastrointestinal [Gl] endoscopic procedures and patient satisfaction in endoscopy suite of South Asian country. Patients coming to the endoscopic suite of Aga Khan University Hospital [AKUH] were interviewed and assessed in this cross-sectional study. Quality of Gl endoscopic procedures was evaluated using assessment tools as suggested by The American Society of Gastroenterology. Patient satisfaction after the procedure was assessed using a modified GHAA-9 questionnaire. The questionnaire was statistically evaluated using Pareto analysis and Spearman rank correlation. In this study, 323 patients were evaluated with a mean age of 43 +/- 14.36 years. Out of all the procedures 251 [77.7%] were gastroscopies while 72[22.3%] were colonbscopies. Patients undergoing different therapeautic procedures were 121 in number [37.46%]. Pre-procedure education was rated as excellent or very good by 91.3% of the patients. Midazolam was used for sedation with an average dose of 3 mg. Technically successful procedures included 99.2% gastroscopies and 98.6% colonoscopies. Mean score of patients regarding satisfaction on mGHAA-9 questionnaire was 30 +/- 3.965. Patient dissatisfaction calculated In our study was 3.6% with the length of time spent waiting before procedure and length of time waiting to get an appointment for the procedure contributing to 90% of dissatisfaction. Quality of endoscopic procedures at our centre is at par with international standards with acceptable complication rate and good patient satisfaction

Pakistan remains in the intermediate prevalence area for Hepatitis B with an estimated carrier rate of 25%. Chronic Hepatitis B patients should be considered for treatment if Alanine transaminase [ALT] is persistently elevated in the last 6 months and HBV DNA is > 2000 IU/ml, irrespective of HBeAg status. In case of normal ALT and HBV DNA > 2000 IU/ml, treatment should only be considered if there is advanced fibrosis or cirrhosis on liver biopsy. HBV DNA positive cirrhotic patients should receive treatment irrespective of ALT status. Medicine available for the treatment of Hepatitis B in Pakistan are lamivudine, adefovir, telbivudine, entecavir, standard and pegylated interferon and thymosin. Patients who fail to achieve primary response as evidenced by < 2 log decrease in serum HBV DNA level after 6 months of nucleos [t] ide analogue therapy should have modification of treatment. Add-on adefovir therapy is indicated in those showing resistance to lamivudine or else switch to entecavir. For lamivudine-naive patients who develop drug resistance while on adefovir, add-on or switching to lamivudine, telbivudine or entecavir is indicated. Treatment should be stopped in HBeAg positive patients on oral antiviral agents who seroconvert [disappearance of HBeAg and appearance of anti-HBe antibody] with undetectable HBVDNA documented on two separate occasions at least 6 months apart. In HBeAg negative patients, discontinuation may be considered if undetectable HBV-DNA has been documented on three separate occasions 6 months apart although current evidence seems to support long term therapy in this group
