Objectives: To affirm the mean of serum homocysteine concentration in patient-control group. To affirm the mean of serum vitamine B12 concentration in patient-control group. To affirm the percentage of hyperhomocysteinemia in patient-control group. Methods: To affirm the serum homocysteine and vitamine B12 concentration in fasting (at least in 12 hours). To examine bilan lipid of the blood and to estimate some other risk factors in 128 elderly patients with hypertension (mean age ± 1SD, 72.4 ± 7.6, 60, 60 males, 68 females) and 132 control subjects (mean age ± 1SD, 71.8 ± 7.3, 63 males, 69 females) of similar age and sex were studied, corresponding, at the Tien Giang Central General Hospital (2017). Results: The mean of serum homocysteine concentration in patient group (18.46 ± 5.58 µmol/L) was higher than in control group (11.67 ± 2.65 µmol/L) (p<0.01). The mean of serum vitamine B12 concentration in patient group (539.64 ± 346.23pg/ ml) was the same in control group (556.86 ± 279.45pg/ml) (p>0.05). The percentage of hyperhomocysteinemia in patient group (71.88%) was higher than in control group (18.94%) (p<0.01). Conclusions: There was hyperhomocysteinemia in elderly patients with hypertension. The percentage of hyperhomocysteinemia in elderly patients with hypertension was higher than control group. Hyperhomocysteinemia in elderly patients with hypertension was a new risk factor of cardiovascular disease that is need to be controlled.

Background:Systemic sclerosis is a disorder of connective tissue with unknown cause, affecting the skin and internal organs, characterized by fibrotic changes.Objective:To determine the correlation between serum homocysteine level and interstitial lung involvement in systemic sclerosis. </P><P> Materials and Methods: In this case – control study, 59 patients who fulfilled the ACR/EULAR classification criteria for systemic sclerosis and were referred to Hafez Hospital of Shiraz, Iran, were included as the case group. Fifty nine healthy subjects were involved as the control group. Patients were divided into two groups based on interstitial lung involvement and two subtypes, diffuse and limited type. Serum homocysteine, vitamin B12, and folate levels compared between the controls, and cases groups.Results:Of 59 case and control group, 53 (%89.8) were female and the mean age did not differ in both groups (P=0.929). Thirty five (%59.3) patients had interstitial lung involvement and 38(%64.4) had diffuse cutaneous systemic sclerosis. The mean serum homocysteine level was 13.9±6.3 µmol/L in the case and 13.7±9.2 µmol/L in the control group (P=0.86). The mean serum homocysteine level did not differ between the patients with and without interstitial lung involvement (P=0.52). The patients with lung involvement was older than those without lung involvement (P=0.004). Lung disease was more common in diffuse type (P=0.014).Conclusion:In our study, serum homocysteine level did not differ between the patients and healthy subjects. Also, there was no correlation between serum homocysteine level and lung involvement, but lung involvement was more common in older patients and also diffuse subtype.

The prevalence of parental bereavement was determined in 50 married female outpatients with a DSM-III diagnosis of agoraphobia and in a control group of married female outpatients diagnosed as having non-psychotic psychiatric disorders other than agoraphobia. The two groups were matched for age and overall severity of psychiatric symptoms. Compared with the general population, the patient control group reported a statistically significant excess of parental, but not maternal, bereavement. The agoraphobic group was significantly younger than the control group at the time of parental loss. These data, together with other reports, suggest a contribution of paternal bereavement before the age of 30 years to agoraphobia in married women and a contribution of recent parental bereavement to psychiatric disorder in general.

Background: Migraine is the second most common primary headache disorder that has close link to the neurovascular system. The exact pathogenesis of migraine is still not fully understood but several possible theories have been proposed. Hyperhomocysteinemia is one of the coincidental factors whose association with migraine is yet in obscure. Methods: This case control study was conducted in the department of Neurology, Bangabandhu Sheikh Mujib Medical University, Dhaka. A total of 65 patients, who were diagnosed as migraine (with aura or without aura) according to ICHD-3 criteria, were considered as case group and another 65 patients (age and sex matched) with headache other than migraine were considered as control group. Serum homocysteine levels were estimated for both groups and other relevant investigations were done in selective cases. Comparison of serum homocysteine levels between two groups were done to see association of serum homocysteine level with migraine in adults. Results: A total of 50 women and 15 men with mean age of 31 (±10.41) years and 50 women and 15 men with mean age of 33 (±10.91) years constituted case and control groups, respectively. The mean (±SD) serum homocysteine level in case group 10.71 (±4.16) ìmol/L was significantly higher than control group 7.62 (±2.26) ìmol/L, (P <0.001).The mean value of serum homocysteine level in migraine without aura (MWOA) patients 11.87 (±4.18) ìmol/L was found significantly higher than migraine with aura (MWA) patients 8.23 (±1.51) ìmol/L, (p<0.05). There was no significant correlation between severity of migraine headache and frequency of migraine attack with serum homocysteine level. Conclusion: Serum homocysteine level was found significantly higher in migraineurs than non-migraineurs. Bangladesh Journal of Neuroscience 2017; Vol. 33 (2): 76-82

SUMMARYSkin conductance is a psychophysiological parameter that reflects fundamental processes such as attention and arousal. The present study explored whether deviations in skin conductance activity are associated with severity of schizophrenic symptoms. For this purpose, Skin Conductance Responses (SCRs) to discrete stimuli (80 dB noises) and Skin Conductance Levels (SCLs) of 37 schizophrenic patients and 31 healthy volunteers were recorded. In accordance with previous studies, schizophrenic patients were found to be hyporesponsive compared to healthy controls. More specifically, almost half of the patients (46%) did not react with any SCR to the first 3 stimuli, whereas only 10% of the control group exhibited such a non-responding. Accordingly, the mean amplitude of the first 3 SCRs – as measured in u Siemens – was found to be significantly lower in patients compared to controls. As well, mean SCL was found to be (marginally) elevated in the patient group. This was especially the case for patients who did exhibit SCRs. In the patient group, a negative correlation was found between amplitude of SCRs and symptom severity. This association was mainly carried by a significant correlation between positive symptoms and reduced SCRs. The clinical relevance of these findings is discussed in detail.

 Background: Chronic kidney disease (CKD) includes irreversible destruction of nephrons leading to progressive decline in glomerular filtration rate. A preferential defect in Homocysteine disposal could hypothetically occur in CKD and subsequently lead to hyperhomocysteinemia. Understanding the status of Homocysteine and other parameters in CKD is useful in the management of the disease. Objective of the study is to estimate serum Homocysteine in CKD patients and its association with renal function and serum albumin in patients with CKD.Methods: The study design involves hospital based observational comparative study. The study was conducted in Department of Biochemistry in association with Department of Nephrology of Mahatma Gandhi Medical College and Hospital, Jaipur between May 2017 to June 2018. 100 diagnosed patients of CKD, visiting the Outpatient Department of Nephrology were enrolled as cases for the study. Patients having cardiovascular disease, Chronic liver disease, Age more than 60 years and pregnant females were excluded from study. The control group consists of 100 age and sex matched healthy individuals.Results: The mean serum creatinine levels of case and control group were 7.50±3.74 mg% and 0.83±0.22 mg% respectively. The mean of serum homocysteine levels of subject group was 27.35±12.52 µmol/L while the mean serum homocysteine levels of control group was 11.06±3.52 µmol/L. The serum homocysteine levels were significantly higher in the CKD patient group. The serum level of albumin in CKD patients and control group were 2.86±0.86 g/dl and 4.10±0.58 g/dl respectively. A positive correlation was found between serum creatinine and serum homocysteine levels. A negative correlation between serum homocysteine and serum albumin was found.Conclusions: Findings of the present study exhibit that serum homocysteine levels are elevated in CKD in comparison to healthy controls and it is positively correlated with serum creatinine level.

Aim.The aim of study was to examine the relationship between serum and mammary gland homocysteine levels with the carrier of separate SNP (single nucleotide polymorphism) genes of the folate metabolism system in patients with proliferative diseases and breast cancer.Methods and results.The study included 182 patients with proliferative diseases of the mammary gland in transbaikalia. The control group included 144 women who did not have oncological diseases. The serum homocysteine level and the supernatant of the mammary tissue homogenate were evaluated by high performance liquid chromatography. Genotyping for the detection of polymorphism MTHFRС677T, MTHFRА1298C, MTRA2756G, MTRRA66G was carried out by polymerase chain reaction with the detection of the amplification product in real time. In the course of molecular genetic testing in patients with proliferative diseases of the mammary gland, there was found: 1) the absence of an explicit association of the carriage of genetic polymorphism MTHFRС677T, MTHFRА1298C, MTRA2756G and MTRRA66G with serum homocysteine concentration, however, comparative hyperhomocysteinemia and, to a lesser extent, in women with the benign breast diseases; 2) the highest homocysteine content in the blood in patients with breast cancer whose genotype was characterized by combinations of polymorphic alleles MTR2756G x MTRR66G; 3) that the MTR2756A allele and genotype MTHFR1298AC, especially their combination of MTHFR1298AC x MTR2756A, increase the risk of developing benign breast formations; 4) the effect of the risk alleles MTR2756G and MTRR66GON the concentration of homocystein in the tumor tissue of the mammary gland.Conclusion. These patterns indicate a certain contribution of the polymorphisms studied, especially their additive effect, both in the development of proliferative diseases of the mammary gland and in the possible potentiation of prothrombotic effects in these patients against the background of tumor progression and homocysteine metabolism disorders.

Background Elderly patients with rib fractures carry a high morbidity rate, particularly due to pulmonary complications as decreased respiratory efforts ensue secondary to pain. Risk of bleeds in the elderly on anticoagulant therapy is high. The effort to reduce narcotic use in patients is now a health care priority. We propose that the use of paravertebral analgesia (PVA) pumps is an alternative pain control method with less risk and easy placement. Methods Two hundred and seventy-nine patients were admitted with multiple fractured ribs to the Trauma Center of Community Hospital and treated with the application of continuous PVA via a pump (72 patients). Pain scores were recorded before and after the initiation of the pump. These patients were compared with a group of the remaining 207 patients who received intravenous narcotics only. Results The mean change from baseline in pain scores for all patients was 1.43 (SD = 2.75). The mean change in pain for the treatment group was 1.93 (SD = 2.60), and the change in pain for the control group was 1.24 (SD = 2.79). Change in pain differed between groups (1.3 vs 1.8; P = .01) although it was a small difference. After adjusting for age, gender, Injury Severity Score, Glasgow Coma Scale, number of fractures, and comorbid conditions, there was no significant difference in pain post-procedure (odds ratio = 0.75; P = 0.39) with an effect size of 30% and total sample size of 279. Conclusion The PVA pump using bupivacaine is an effective safe and alternative method for managing elderly patients with rib fractures eliminating the serious side effects associated with narcotics.

Background: Hypertensive disorders complicate upto 5 to 10% of all pregnancies. Though the exact cause of pre-eclampsia is still undecided, maternal hyperhomocysteinemia has been implicated as a risk factor for pre eclampsia, placental abruption and other vascular diseases. The objectives of present study were to estimate the levels of serum homocysteine in antenatal patients and to study the above parameters in patients of pre-eclampsia.Methods: A prospective observational study was performed with 30 pre eclamptic patients and an equal number taken as control having comparable demographic characteristics. Level of homocysteine was measured by an enzymatic method, using Diazyme homocysteine 2 reagent enzymatic assay kit on Beckman coulter analyzer in all the patients. Obstetrics and neonatal outcomes were observed in all the patients. The statistical analysis was done using unpaired T test for determining level of significance.Results: Mean Serum homocysteine in the study group was 13.99±5.46 µmol/l and was 6.03±2.58 µmol/l in control group. This was statistically significant (p value 0.002). However the mean values of serum homocysteine did not correlate with severity of pre-eclampsia 14.32±6.72 µmol/l in mild pre-eclampsia and 13.60±3.77μmol/l in severe pre-eclampsia respectively (p value - 0.727).Conclusions: It appears that maternal serum homocysteine has a causal role in pathogenesis of pre eclampsia, however to recommend it as a routine test, larger studies are required.

Abstract Age-related cataracts (ARC) are the leading cause of visual impairment and blindness, affecting 16 million subjects globally. This work aimed to investigate the correlation of serum homocysteine (Hcy), folate, vitamin B6 (VitB6) and ARC. We prospectively enrolled 60 ARC, and 58 age-matched healthy controls in this study. The serum concentrations of Hcy were determined using a fully automatic biochemical analyzer and folate/VitB6 by enzyme-linked immunosorbent assay (ELISA). The diagnostic performance of serum Hcy, folate and VitB6 for ARC were evaluated by receiver operating characteristics (ROC). The mean serum levels of Hcy, folate and VitB6 from the control group were 9.8 ± 2.1 μmol/L, 17.4 ± 2.3 nmol/L, 42.3 ± 5.7 pmol/L, respectively. In comparison, the mean serum levels of Hcy, folate and VitB6 from the ARC group were 12.2 ± 2.5 μmol/L, 15.3 ± 2.6 nmol/L, 40.3 ± 5.1 pmol/L, respectively. Significant statistical difference (p<0.05) were found between the control and ARC groups. The diagnostic sensitivity, specificity and AUC of serum Hcy as a biomarker for ARC were 53.1%, 76.3% and 0.66 (95% CI:0.61-0.76), respectively, which were superior to that of serum folate and VitB6. Serum Hcy was significantly elevated in ARC patients and correlated with ARC development, thus may be used as a serological marker for ARC diagnosis.

AbstractPseudotumor cerebri syndrome (PTCS) is characterized by raised intracranial pressure (ICP) with no neuroradiological abnormalities. Ocular ultrasound has been in use to measure optic nerve sheath diameter (ONSD), and retinal artery Doppler indices have been used for indirect assessment of ICP by pediatric intensivists. Here, we aimed to evaluate the correlation of the lumbar puncture (LP) opening pressure with the ultrasonographic ONSD and retinal resistive index (RRI) measures in patients with PTCS. And we wanted to find an answer to the following question: Can ultrasonographic ONSD measures serve as a follow-up tool in patients with PTCS? A prospective, single-center, case–control study was performed by pediatric intensive care and pediatric neurology departments. A total of 7 patients with PTCS were evaluated as patient group and 15 healthy children were evaluated as control group. The mean age of patient group was 138.8 ± 43.7 months. The mean right ONSD was 6.7 ± 0.5 mm and the mean left ONSD was 6.7 ± 0.6 mm. The mean right RRI value was 0.73 ± 0.03 and the mean left RRI was 0.73 ± 0.09. For the patient group, ONSD and RRI values of both eyes were statistically significant higher values than for the control group. The mean LP opening pressure was 56.57 ± 16.36 cmH2O. We detected strong, positive, and statistically significant correlations between the LP opening pressure and ONSD baseline measures for both the right eye (r = 0.882, p = 0.009) and the left eye (r = 0.649, p = 0.004). There was no correlation between opening pressure in LP and RRI measurements. We detected a statistically significant decrease in the right ONSD and left ONSD values and visual analog scale scores at the third-month follow-up. Our study results demonstrate that ultrasonographic ONSD measurements can be used as a noninvasive tool for assessment of the ICP at first admission and can be used as a follow-up tool in PTSC patients.
