ABSTRACT
This study aimed to determine the association between GERD [Gastro-Esophageal Reflux Disease] symptoms and Body Mass Index [BMI] in the outpatients of Abbasi Shaheed Hospital, Karachi. A comparative cross-sectional study was conducted in Abbasi Shaheed Hospital, Karachi from December 2008 to March 2009. By convenient sampling method, 200 outpatients who met the inclusion criteria were enrolled in the study, visiting the hospital with symptoms of epigastric pain, nausea, vomiting, acid regurgitation, heart burn, burping, belching, and feeling of wind. A questionnaire was filled, which contained patient's demographic profile, information on the frequency of all GERD symptoms and severity of main GERD symptoms. History of smoking, alcohol, drugs or any illness were also inquired and noted. Statistical analysis was done by SPSS version 16. Among 200 outpatients, 65% were females and 35% were male. Mean age was 38.4 years. Nausea was complained in 87%, epigastric pain in 66%, acid regurgitation in 66% and heart burning in 64% of patients. The frequency of heartburn and acid regurgitation was seen once a week in 39% and 45% of patients respectively while severity of heartburn and acid regurgitation was found 25% and 33% of patients respectively and there relation with body mass index were found insignificant. Co-relation of body mass index was not associated with symptoms of gastro-esophageal reflux disease i.e.: nausea [p=0.06], epigastric pain [p=0.658], acid regurgitation [p=0.935], heart burn [0.525]. Our study concludes that in our setting, the symptoms of GERD occur independently of body mass index. It seems that high BMI plays a more important role to cause symptoms of GERD among western population but not in Asian populations. However, further studies in Asian communities are also required in this regard
ABSTRACT
To measure the changes in oxygen saturation using pulse oximetry during flexible upper gastrointestinal endoscopy in unsedated patients. This is an observational study conducted on 356 patients undergoing unsedated upper gastrointestinal Endoscopy, during April 2009 to January 2010. Complete demographic data, systemic history, smoking history, laboratory evaluation and American Society of Anesthesiologists Physical Status [ASA-PS] were recorded in all patients. Patients with severe systemic disease [ASA-PS III-VI], those who needed emergency endoscopy and with anemia of hemoglobin <8gm/dl were excluded from the study. Out of 356 patients 186 [52.2%] were male and 170 [47%.8] were female. All the patients tolerated the procedure well at the start and at the end and had no oxygen desaturation. At mid of the procedure 21 [5.9%] patients showed mild oxygen desaturation and 4 [1.1%] showed moderate oxygen desaturation while 331 [93%] showed no oxygen desaturation. No patient at any stage showed severe oxygen desaturation. Relationship of smoking, co-morbidity and clinical signs with mid procedure oxygen saturation is insignificant in both genders. It is concluded that mild to moderate hypoxia is some what common during therapeutic endoscopic procedure and of no serious consequence. However, severe hypoxia is not recorded in our study. The unsedated gastrointestinal endoscopy is a safe procedure for the diagnostic purpose, as it does not produce hypoxia during this; therefore pulse oximetry is not a precondition in patients undergoing unsedated diagnostic endoscopy without severe systemic disease. We recommend monitoring through pulse oximetry in patients with age greater than 45 years and procedure longer than 8 minutes

To determine the frequency of seropositive dengue infection using rapid immunochromatographic assay in patients with probable dengue infection as per WHO criteria. A cross-sectional observational study was conducted at Abbasi Shaheed Hospital, Karachi from July 2008 to January 2009. Patieats presenting with acute febrile illness, rashes, bleeding tendencies, leucopenia and or thrombocytopenia were evaluated according to WHO criteria for probable dengue infection. Acute phase sera were collected after 5 days of the onset of fever as per WHO criteria. Serology was performed using rapid immunochromatographic [ICT] assay with differential detection of IgM and IgG. A primary dengue infection was defined by'a positive IgM band and a negative IgG band whereas secondary infection was defined by a positive IgG band with or without positive IgM band. Among 599 patients who met the WHO criteria for dengue infection, 251[41.9%] were found to be ICT reactive among whom 42 [16.73%] had primary infection. Secondary infection was reported in 209 [83.26%]. Acute phase sera of 348 [58.09%] were ICT non reactive. Four patients died because of dengue shock syndrome among which three had secondary infection. Early identification of secondary infection in acute phase sera using rapid ICT is valuable in terms of disease progression and mortality. However in highly suspected cases of dengue infection clinical management should not rely on negative serological results
