Does the Capsule Method Increase the Accuracy of the Detection of Ger by Scintigraphy Technique?

Background: The scintigraphy technique is the most sensitive test for the detection of gastroesophageal reflux disease (GERD). Scintigraphy techniques employ two methods: the liquid method and the capsule method. Aim: In this prospective study, we are trying to find out the efficiency of the capsule method for gastroesophageal reflux scintigraphy over the liquid method and to determine the ease of execution of the technique and the interpretation of the results. Materials and Methods: A total of 65 symptomatic patients (age range: 7-71 years; mean age: 35.2 years) were included in the study. They were divided into two groups: group A, which included 18 patients who underwent the liquid method and Group B, which included 47 patients who underwent the capsule method. The average administered dose of 99mTc-labeled sulfur colloid was 11.1-18.5 MBq. Results: The results showed that 45 (69.12%) of the 65 patients tested positive for GERD. Furthermore, 15 were positive in the liquid method and 30 in the capsule method. Grade III reflux was seen in 66.67% of patients, and 33.33% of patients with Grade II and I reflux were diagnosed using both methods. Conclusion: Thus, in conclusion, we can say that both liquid and capsule methods are equally sensitive for the detection of low as well as high refluxate volumes.

Evaluation of obstructive sleep apnea in metabolic syndrome.

BACKGROUND: Metabolic syndrome has become one of the most important public health problems with a growing prevalence in both developed and developing countries. Obesity is a major risk factor for obstructive sleep apnea (OSA), which is associated with significant cardiorespiratory morbidity. AIMS: The aims of this study were to find out the prevalence of OSA in patients with metabolic syndrome and to highlight the importance of assessment of OSA in these patients. METHODS: This cross-sectional analytical study was conducted on 100 subjects aged 30-60 years, comprising 50 cases of metabolic syndrome and 50 controls without metabolic syndrome. Overnight polysomnography was done in all the subjects. Prevalence and severity of OSA were assessed and compared between the two groups. RESULTS: Prevalence of OSA was significantly higher (66%) in patients with metabolic syndrome than in subjects without metabolic syndrome (12%). Out of 33 (66%) OSA patients with metabolic syndrome, 8 (16%) had mild OSA, 11 (22%) had moderate OSA, and 14 (28%) had severe OSA. Increasing severity of OSA was associated with higher mean levels of all the metabolic syndrome parameters except serum high density lipoprotein (HDL). CONCLUSIONS: OSA is highly prevalent in patients with metabolic syndrome. Also, the increasing severity of OSA is associated with poorer control of diabetes, hypertension, and dyslipidemia, which are all components of metabolic syndrome. Therefore, effective treatment of metabolic syndrome can prevent and control OSA in these patients. Similarly, reducing the severity of OSA (by early diagnosis and treatment) in patients with metabolic syndrome might help to optimize control of blood sugar, blood pressure, and serum lipids, thereby reducing the risk of cardiovascular disease. Therefore, the need for screening metabolic syndrome patients for OSA has been reinforced by this study.

Asymptomatic bacteriuria among the patients of type 2 diabetes mellitus.

BACKGROUND: Asymptomatic bacteriuria (ASB) is common in neonates, preschool children, pregnant women, elderly, diabetics, catheterized patients, and patients with abnormal urinary tracts or renal diseases. Though there is currently no consensus on treatment of ASB in various population groups, it is advisable to treat the same in patients with diabetes mellitus (DM). AIMS: To determine the prevalence of ASB in patients with type 2 DM and to study the spectrum of uro-pathogens causing ASB along with their antibiotic susceptibility profile. SETTINGS AND DESIGN: This prospective, observational study was conducted in the department of Medicine of a tertiary care teaching hospital. METHODS: The study was conducted on 100 patients with type 2 DM. Urine wet mount and gram stain examination was done for all to detect the presence of pus cells and bacteria in urine. Antibiotic sensitivity testing was performed in patients with significant bacteriuria to determine the sensitivity profile of isolated uro-pathogens. The data were analyzed to determine the association between diabetes and ASB. RESULTS: ASB was common among diabetics, as evident by a prevalence of 21%. Presence of ASB showed positive correlation with poor glycemic control. Escherichia coli (E. coli) was the most common organism causing ASB followed by Candida, Pseudomonas, Klebsiella, and Citrobacter. E. coli isolated from study patients was most sensitive to imipenem and nitrofurantoin (NFT). CONCLUSIONS: ASB is common among diabetics, with poor glycemic control being a significant risk factor. E. coli is the most common organism causing ASB in diabetics, and it is most sensitive to imipenem and NFT.

Impact of health education on knowledge, attitude, practices and glycemic control in type 2 diabetes mellitus.

BACKGROUND: Effective health education consequently improves knowledge, attitude, and practices (KAP) leading to better glycemic control and is widely accepted as an integral part of comprehensive diabetes care for affected individuals and their families in primary care settings. AIMS: To assess the impact of health education on knowledge, attitude, practices, and glycemic control in type 2 diabetes mellitus patients. SETTINGS AND DESIGN: This case control study was conducted in the department of Medicine of a tertiary care teaching hospital. METHODS: The study was conducted on 100 diabetic subjects aged more than 40 years comprising of 50 cases and 50 controls. Cases were given education on their disease, drugs, dietary, and lifestyle modifications along with patient education leaflet at baseline and at first follow-up, while controls received neither of these. Subjects were assessed for KAP by administering KAP questionnaire and for glycemic control by measuring glycated hemoglobin (HbA1C) at baseline and at the end of the study. RESULTS: In this study, end mean knowledge, attitude, practice, and KAP SUM scores of cases (10.28 ± 1.78, 3.46 ± 0.93, 3.14 ± 0.86, and 16.82 ± 3.40, respectively) showed significant increase from the baseline (3.86 ± 0.93, 1.00 ± 0.83, 0.40 ± 0.64, and 5.26 ± 2.10, respectively) compared to controls, accompanied by significant reduction in HbA1C of cases at the end of the study compared to the controls. CONCLUSIONS: Effective health education improves knowledge, attitude, and practices, particularly with regard to lifestyle modifications and dietary management, culminating into better glycemic control that can slow down the progression of diabetes and prevent downstream complications.

Correlation of Parathyroid Hormone Levels with Mineral Status in End-stage Renal Disease Patients.

Parathyroid hormone (PTH) is the main regulator of calcium, phosphate, magnesium, sodium, and potassium homeostasis. Therefore, this study was conducted to evaluate the relationship between PTH and aforementioned minerals in end-stage renal disease (ESRD) patients. AIM: The aim of this study was to estimate serum intact parathormone (iPTH) and other biochemical parameters in ESRD patients and to find correlation between serum iPTH and biochemical parameters in the study group. RESULTS: This cross-sectional study included 60 clinically diagnosed patients of ESRD of age (>18 years), either sex. Disordered mineral metabolism is common complications of ESRD patients. The mean value of calcium, phosphorus, and magnesium was 7.90 ± 1.16 mg/dL, 6.44 ± 1.72 mg/dL, and 2.57 ± 0.62 mg/dL, respectively, indicating hypocalcemia, hyperphosphatemia, and hypermagnesemia in ESRD patients. To compensate the deranged mineral status, increased levels of PTH were seen in ESRD patients with mean value of 173.93 ± 62.62 pg/mL. There was a statistically significant positive correlation found between PTH and S. creatinine (P ≤ 0.001; r = 0.596), whereas the statistically significant negative correlation found between PTH and eGFR (P ≤ 0.001; r = -0.525). A significant positive correlation found between PTH and phosphorous (P = 0.003; r = 0.378) and potassium (P ≤ 0.001; r = 0.421). On the other hand, significant negative correlation found with calcium (P ≤ 0.001; r = -0.805) and corrected calcium (P = <0.001; r = -0.769). But nonsignificant association was found with magnesium, sodium, and calcium × phosphorous (P > 0.05). CONCLUSION: It was concluded that PTH is playing crucial role in mineral metabolism; it should be frequently assessed in order to prevent any untoward mineral decompensation and to prevent complications like bone disease and extra skeletal calcification, and decrease cardiac disease risk in ESRD patients.

Hepatitis B virus and hepatitis C virus co-infection in hemodialysis patients: A retrospective study from a tertiary care hospital of North India.

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.

Hepatitis C Virus (HCV) Infection among Seronegative Patients undergoing Haemodialysis in a Remotely Located Tertiary Care Hospital of Northern India: Value of HCV-RNA and Genotypes.

BACKGROUND: Haemodialysis (HD) patients are at an increased risk of Hepatitis C virus (HCV) infection, which is significantly associated with increased morbidity and mortality. AIM: The aim of this study was to find the prevalence of HCV infection in anti-HCV antibody negative haemodialysis patients by Real-time PCR (RT-PCR) and value of HCV-RNA among seronegative patients undergoing haemodialysis in a remotely located tertiary care hospital. MATERIALS AND METHODS: A total of 100 chronic renal failure patients on haemodialysis were studied. All the patients were screened for anti-HCV antibodies by ELISA test and for HCV-RNA by RT-PCR. RESULTS: The overall prevalence of HCV infection was 32%. Antibody positivity was 30% and HCV-RNA by RT-PCR was detected in 20%. HCV-RNA in seronegative patients was detected in 2.8%. CONCLUSION: Serological assays (30%) are quite reliable for detecting HCV infection in patients undergoing haemodialysis in our tertiary care hospital. Only a small proportion of them (2.8%) require the documentation of viral genome for current infection.
