1.  Helicobacter pylori eradication in patients with chronic immune thrombocytopenic purpura 
AIM: To assess the effect of Helicobacter pylori (H. pylori) eradication on platelet counts in patients with chronic immune thrombocytopenic purpura (cITP).
METHODS: A total of 36 cITP patients were included in the study. The diagnosis of H. pylori was done by rapid urease test and Giemsa staining of the gastric biopsy specimen. All H. pylori positive patients received standard triple therapy for 14 d and were subjected for repeat endoscopy at 6 wk. Patients who continued to be positive for H. pylori on second endoscopy received second line salvage therapy. All the patients were assessed for platelet response at 6 wk, 3rd and 6th months.
RESULTS: Of the 36 patients, 17 were positive for H. pylori infection and eradication was achieved in 16 patients. The mean baseline platelet count in the eradicated patients was 88615.38 ± 30117.93/mm3 and platelet count after eradication at 6 wk, 3 mo and 6 mo was 143230.77 ± 52437.51/mm3 (P = 0.003), 152562.50 ± 52892.3/mm3 (P = 0.0001), 150187.50 ± 41796.68/mm3 (P = 0.0001) respectively and in the negative patients, the mean baseline count was 71000.00 ± 33216.46/mm3 and at 6 wk, 3rd and 6th month follow up was 137631.58 ± 74364.13/mm3 (P = 0.001), 125578.95 ± 71472.1/mm3 (P = 0.005), 77210.53 ± 56892.28/mm3 (P = 0.684) respectively.
CONCLUSION: Eradication of H. pylori leads to increase in platelet counts in patients with cITP and can be recommended as a complementary treatment with conventional therapy.

2.  Association of hypertension status and cardiovascular risks with sympathovagal imbalance in first degree relatives of type 2 diabetics 
Abstract
Aims/Introduction
As reports show cardiovascular (CV) risks in first‐degree relatives (FDR) of type 2 diabetics, and autonomic imbalance predisposing to CV risks, in the present study we have assessed the contribution of sympathovagal imbalance (SVI) to CV risks in these subjects.
Materials and Methods
Body mass index (BMI), waist‐to‐hip ratio (WHR), basal heart rate (BHR), blood pressure (BP), rate pressure product (RPP), and spectral indices of heart rate variability (HRV) were reordered and analyzed in FDR of type 2 diabetics (study group, n = 293) and in subjects with no family history of diabetes (control group, n = 405).
Results
The ratio of low‐frequency (LF) to high‐frequency (HF) power of HRV (LF–HF), a sensitive marker of SVI, was significantly increased (P < 0.001) in the study group compared with the control group. The SVI in the study group was due to concomitant sympathetic activation (increased LF) and vagal inhibition (decreased HF). In the study group, the LF–HF ratio was significantly correlated with BMI, WHR, BHR, BP and RPP. Multiple regression analysis showed an independent contribution of LF–HF to hypertension status (P = 0.000), and bivariate logistic regression showed significant prediction (odds ratio 2.16, confidence interval 1.130–5.115) of LF–HF to increased RPP, the marker of CV risk, in the study group.
Conclusions
Sympathovagal imbalance in the form of increased sympathetic and decreased parasympathetic activity is present in FDR of type 2 diabetics. Increased resting heart rate, elevated hypertension status, decreased HRV and increased RPP in these subjects make them vulnerable to CV risks. SVI in these subjects contributes to CV risks independent of the degree of adiposity.

7.  Sympathovagal Imbalance Contributes to Prehypertension Status and Cardiovascular Risks Attributed by Insulin Resistance, Inflammation, Dyslipidemia and Oxidative Stress in First Degree Relatives of Type 2 Diabetics 
PLoS ONE  2013;8(11):e78072.
Background
Though cardiovascular (CV) risks are reported in first-degree relatives (FDR) of type 2 diabetics, the pathophysiological mechanisms contributing to these risks are not known. We investigated the association of sympathovagal imbalance (SVI) with CV risks in these subjects.
Subjects and Methods
Body mass index (BMI), basal heart rate (BHR), blood pressure (BP), rate-pressure product (RPP), spectral indices of heart rate variability (HRV), autonomic function tests, insulin resistance (HOMA-IR), lipid profile, inflammatory markers, oxidative stress (OS) marker, rennin, thyroid profile and serum electrolytes were measured and analyzed in subjects of study group (FDR of type 2 diabetics, n = 72) and control group (subjects with no family history of diabetes, n = 104).
Results
BMI, BP, BHR, HOMA-IR, lipid profile, inflammatory and OS markers, renin, LF-HF (ratio of low-frequency to high-frequency power of HRV, a sensitive marker of SVI) were significantly increased (p<0.0001) in study group compared to the control group. SVI in study group was due to concomitant sympathetic activation and vagal inhibition. There was significant correlation and independent contribution of markers of insulin resistance, dyslipidemia, inflammation and OS to LF-HF ratio. Multiple-regression analysis demonstrated an independent contribution of LF-HF ratio to prehypertension status (standardized beta 0.415, p<0.001) and bivariate logistic-regression showed significant prediction (OR 2.40, CI 1.128–5.326, p = 0.002) of LF-HF ratio of HRV to increased RPP, the marker of CV risk, in study group.
Conclusion
SVI in FDR of type 2 diabetics occurs due to sympathetic activation and vagal withdrawal. The SVI contributes to prehypertension status and CV risks caused by insulin resistance, dyslipidemia, inflammation and oxidative stress in FDR of type 2 diabetics.

9.  Cerebral infarction leading to hemiplegia: A rare complication of acute pancreatitis 
Peripancreatic vascular thrombosis is a known complication of acute pancreatitis (AP) and chronic pancreatitis. However, hemiplegia resulting from cerebral infarction due to cerebral arterial thrombosis is a rare complication of AP. Here, we report a case of alcohol related severe AP with multi-organ dysfunction, which was complicated by large left sided middle cerebral artery territory infarct - leading to right sided hemiplegia in a 48-year-old male patient. The neurological and vascular thrombotic complications of pancreatitis, their pathogenesis and management are discussed in brief.

12.  Etiology and outcome determinants of intracerebral hemorrhage in a south Indian population, A hospital-based study 
Background:
There is paucity of methodologically sound published studies on intracerebral hemorrhage (ICH) from India, on pub med/embase search.
Aims:
To explore etiology of ICH and correlate the causes, location, and size of hemorrhage to clinical outcome.
Materials and Methods:
A hospital-based descriptive study from South Indian eastern coastal town of Puducherry; 60 consecutive subjects aged > 12 years, predominantly of inbred Tamil population, with head CT evidence of intracerebral hemorrhage not associated with trauma and brain tumors, were recruited. Outcome at three months was measured using Glasgow Outcome scale, NIHSS and mortality. SPSS v 19 was used for statistical analysis.
Results:
Commonest etiological factor was hypertension, followed by bleeding diathesis, thrombolysis for myocardial infarction, and cortical vein thrombosis. Most frequent locations of hematoma were basal ganglia, thalamus, internal capsule, and cerebral and cerebellar parenchyma. Hematoma volume correlated significantly with systolic and mean arterial pressure but not with diastolic blood pressure. Poor outcome was correlated to size (P < 0.05) and intraventricular extension of hematoma (P < 0.05), and to systolic, diastolic and mean arterial pressure, but not to age, gender, smoking, alcoholism, ischemic heart disease, and blood sugar level. Among diabetic patients with ICH, the size of hematoma (P = 0.04) and severity of coma (P = 0.01) at admission were significantly worse compared to the non-diabetic, but not the outcome at three months [Glasgow outcome scale or mortality (P = 0.94 and 0.14)].
Conclusions:
The location of hemorrhage and correlation with outcome agreed with the patterns described for the non-white races in prior reports. Independence of outcome to diabetic status despite a more severe initial presentation may indicate importance of good care, even in high risk groups.

13.  Body mass index contributes to sympathovagal imbalance in prehypertensives 
Background
The present study was conducted to assess the nature of sympathovagal imbalance (SVI) in prehypertensives by short-term analysis of heart rate variability (HRV) to understand the alteration in autonomic modulation and the contribution of BMI to SVI in the genesis of prehypertension.
Methods
Body mass index (BMI), basal heart rate (BHR), blood pressure (BP), rate pressure product (RPP) and HRV indices such as total power (TP), low-frequency power (LF), normalized LF (LFnu), high-frequency power (HF), normalized HF (HFnu), LF-HF ratio, mean heart rate (mean RR), square root of the mean squared differences of successive normal to normal intervals (RMSSD), standard deviation of normal to normal RR interval (SDNN), the number of interval differences of successive NN intervals greater than 50 ms (NN50) and the proportion derived by dividing NN50 by the total number of NN intervals (pNN50) were assessed in three groups of subjects: normotensives having normal BMI (Group 1), prehypertensives having normal BMI (Group 2) and prehypertensives having higher BMI (Group 3). SVI was assessed from LF-HF ratio and correlated with BMI, BHR, BP and RPP in all the groups by Pearson correlation. The contribution of BMI to SVI was assessed by multiple regression analysis.
Results
LF and LFnu were significantly increased and HF and HFnu were significantly decreased in prehypertensive subjects in comparison to normotensive subjects and the magnitude of these changes was more prominent in subjects with higher BMI compared to that of normal BMI. LF-HF ratio, the sensitive indicator of sympathovagal balance had significant correlation with BMI (P = 0.000) and diastolic blood pressure (DBP) (P = 0.002) in prehypertensives. BMI was found to be an independent contributing factor to SVI (P = 0.001) in prehypertensives.
Conclusions
It was concluded that autonomic imbalance in prehypertensives manifested in the form of increased sympathetic activity and vagal inhibition. In prehypertensives with higher BMI, vagal withdrawal was predominant than sympathetic overactivity. Magnitude of SVI (alteration in LF-HF ratio) was linked to changes in BMI and DBP. BMI had an independent influence on LF-HF ratio. It was advised that life-style modifications such as yoga and exercise would enable achieve the sympathovagal balance and blood pressure homeostasis in prehypertensives.

14.  Clinico-aetiologic profile of macrocytic anemias with special reference to megaloblastic anemia 
Purpose of study
This study was conducted to study the clinical and laboratory parameters in patients with macrocytic anemia and to determine the etiology of macrocytic anemia with special reference to megaloblastic anemia.
Materials and methods
This study was a cross-sectional descriptive study carried over a period of 18 months on 60 adult patients (age ≥13 years) of macrocytic anemia. Macrocytic anemia was identified when peripheral blood examination showed anemia with a mean red blood corpuscular volume of >95 fl.
Result
The most common cause of macrocytic anemia was megaloblastic anemia (38.4%). The major causes of nonmegaloblastic macrocytic anemia were primary bone marrow disorders (35%), liver diseases (15%) and hemolytic anemia (8.3%). There was a significant male preponderance in the study (65%). The megaloblastic anemias observed were due to either vitamin B12 deficiency (78.3%) or combined B12 and folate deficiency (21.7%). A significant proportion of non-vegetarians (73.9%) had megaloblastic anemia. Patients with an MCV of >110fl were more likely to have megaloblastic anemia (p value 0.0007). Three patients (mean age 55 years) with a megaloblastic marrow did not respond to vitamin replacement and were found to have myelodysplastic syndrome.
Conclusion
Megaloblastic anemia due to Vitamin B12 or folate deficiency remains the most important cause of macrocytic anemia. In settings with limited laboratory facilities, a therapeutic trial of vitamins B12 or folic acid is useful in determining the specific vitamin deficiency.
