Epidemiology of Hepatitis B in the Reproductive-Age Female Farmworkers of Southeastern Turkey

Background:

There are limited data on the prevalence of the hepatitis B virus (HBV) infection in the agricultural population worldwide.

Objectives:

This study aimed to determine the prevalence of HBV infection and associated risk factors in the reproductive-age female farmworker.

Materials and Methods:

This cross-sectional study was conducted between January and April 2013 in southeastern region (SAR) of Turkey. A community-based representative agricultural sample (n = 705) from the agricultural areas of nine provinces of SAR was randomly determined by clustering method using Epi Info software. Questionnaires including demographic information and risk factors of HBV were administered to participants. The presence of HBsAg, anti-HBs, anti-HBc, and anti-HBe antibodies in blood samples were measured by ELISA.

Results:

The prevalence of the HBsAg, anti-HBs, anti-HBc, anti-HBe antibodies, and seropositivity were 5.7%, 25.9%, 28.9%, 16.4%, and 36.7%, respectively. There was no association between the HBsAg and the size of the household, age, education level, parity, and place of birth while the prevalence of HBsAg was higher in seasonal migratory farmworkers and people living in urban areas and the prevalence of anti-HBs antibody was significantly higher in women ≥ 35 years of age, those with a high parity, and those who gave birth without the assistance of health professionals (P < 0.05). The risk for HBV infection in the seasonal migratory group was 4.3 times higher in comparison to local workers (P = 0.00; OR = 4.3; 95% CI, 2.2-8.4), with a prevalence rate of 11%.

Conclusions:

The monitoring of at-risk groups like seasonal migratory farmworkers is necessary to strengthen the healthcare service provided to this population.     

D-dimer level predicts in-hospital mortality in patients with infective endocarditis: A prospective single-centre study

Background

Increased circulating D-dimer levels have been correlated with adverse outcomes in various clinical conditions. To our knowledge, the association of on-admission D-dimer and in-hospital mortality in infective endocarditis (IE) has not been investigated. We hypothesized that increased on-admission D-dimer levels would correlate with adverse outcomes when prospectively studied in patients with IE.

Methods

In this prospective study, a total of 157 consecutive patients with the definite IE diagnosis met the inclusion criteria and underwent testing for on-admission D-dimer and CRP assays. The outcome measure was in-hospital death from any cause.

Results

In-hospital mortality occurred in 40 (26%) patients. Increased levels of plasma D-dimer (5.1 ± 1.7 vs 1.9 ± 0.8, p < 0.001), CRP [45(13-98) vs 12(5–28), p < 0.001] were found in dead patients compared with those survived. In addition to S. aureus infection, increased leukocyte count, end-stage renal disease, LVEF < 50%, vegetation size of > 10 mm, perivalvular abscess, on-admission D-dimer (HR: 1.32; 95% CI: 1.24-1.40; p < 0.001) and CRP (HR: 1.18; 95% CI: 1.09-1.36; p = 0.001) levels were significantly associated with in-hospital mortality. Furthermore, the sensitivity and specificity of D-dimer ≥ 4.2 mg/L in predicting in-hospital death in IE were 86% and 85%, respectively. Moreover, the sensitivity and specificity of CRP levels ≥ 13.6 mg/L were 72% and 69%, respectively.

Conclusion

Our findings suggest that on-admission D-dimer level may be a simple, available and valuable biomarker that allows us to identify high-risk IE patients for in-hospital mortality. D-dimer ≥ 4.2 mg/L, CRP ≥ 13.6 mg/L were independently associated with IE related in-hospital death.     

A case of primary Sjögren’s syndrome presenting primarily with central nervous system vasculitic involvement

Sjögren’s syndrome is primarily a chronic systemic autoimmune disease that affects exocrine organs. Neurologic symptoms frequently present as peripheral neuropathy due to small vessel vasculitis. Type and prevalence of central nervous system involvement are still controversial. In this report, we present a 35-year-old woman with primary Sjögren’s syndrome with central nervous system vasculitic involvement.     

The horror of unsafe abortion: case report of a life threatening complication in a 29-year old woman

Background

Every year 42 million women with unintended pregnancies choose abortion, and fifty percent of these procedures, 20 million are unsafe. An unsafe abortion is defined as a procedure for terminating an unintended pregnancy carried out either by person lacking the necessary skills or in an environment that does not conform to minimal medical standards or both.Pakistan is the one of the six countries where more than 50% of the world’s all maternal deaths occur. It is estimated that 890,000 induced abortions are performed annually in Pakistan, and estimate an annual abortion rate of 29 per 1000 women aged 15-49.

Case presentation

Here we present a case report of a 29-year old woman who underwent an unsafe abortion for unintended pregnancy resulting in uterine perforation. The unskilled provider pulled out her bowel through vagina after perforating the uterus, as a result she lost major portion of her small intestine resulting in short bowel syndrome.

Conclusion

The law of Pakistan only allows abortion during early stages of pregnancy for purpose of saving the life of a mother but does not cater for cases of rape, incest and fetal abnormalities or social reasons.Only legalization of abortion is not sufficient, preventing unintended pregnancy should be the priority of all the nations and for this reason contraception should be widely accessible.Practitioners need to become better trained in safer abortion methods and be to able transfer the patient to health facility when complications occur.

     

A neuronal aging pattern unique to humans and common chimpanzees

Lipofuscin pigment accumulation is among the most prominent markers of cellular aging in postmitotic cells. The formation of lipofuscin is related to oxidative enzymatic activity and free radical-induced lipid peroxidation. In various mammals such as rat, dog, macaque as well as in cheirogaleid primates, most of the large neurons, such as cerebellar Purkinje cells and neocortical pyramidal cells, show heavy lipofuscin accumulation in adulthood. In contrast, a well-known yet poorly studied feature of the aging human brain is that although lipofuscin accumulation is most marked in large neurons of the cerebral cortex, the large neurons of the cerebellar cortex—the Purkinje cells—appear to remain free of lipofuscin accumulation. It is however, not known whether this characteristic of human Purkinje cells is shared with other primates or other mammals. This study reports results from histological observation of Purkinje cells in humans, non-human primates, and other mammals. Procedures include histochemistry, immunocytochemistry, and fluorescence microscopy. Abundant lipofuscin deposition was observed in Purkinje cells of all the species we examined except Homo sapiens (including Alzheimer’s disease cases) and Pan troglodytes. In contrast, lipofuscin deposition was observed in neurons of the dentate nucleus. Our findings suggest that when compared with other primates, Purkinje cells in chimpanzees and humans might share a common aging pattern that involves mechanisms for neuroprotection. This observation is important when considering animal models of aging.     

Frequency and features of nocturnal enuresis in Pakistani children aged 5 to 16 years based on ICCS criteria: a multi-center cross-sectional study from Karachi,Pakistan

Background

Nocturnal enuresis (NE) is a common symptom in children worldwide. International Children’s Continence Society (ICCS) defines enuresis as either mono-symptomatic, NE with lower urinary tract symptoms and NE with co-morbid conditions. The objectives of this study were to determine the frequencies and types of NE and associated symptoms and conditions in children aged 5 to 16?years based on ICCS criteria.

Methods

A multi-center cross sectional study was conducted between November 2012 and December 2013 in the primary care clinics of four hospitals in Karachi. Children aged five to fifteen years were included through consecutive sampling. Informed consent was obtained from the parents and a pre-coded semi-structured questionnaire was used to obtain the information. Data was entered on SPSS version 20.0 and multivariable logistic regression analysis was used for data analysis.

Results

Out of 429 children aged between five and sixteen years, 243(56.9%) were boys and the remaining 186(43.1%) were girls. One hundred and eighty three children (43%) had nocturnal enuresis (NE). Forty four (10.3%), had mono-symptomatic NE, 57(31.1%) had associated lower urinary tract symptoms (NE-LUTS), whereas 30 (16.3%) had NE with a co-morbid condition. Fifty two (28.4%) NE’s had at least one of both LUTS and a co-morbid condition. Out of the 246(57%) non-enuretic’s, 31(12.6%) had a LUTS, 95(38.6%) had a co-morbid condition and 57(23.2%) had at least one of both LUTS and a co-morbid condition. The remaining 63 (25.6%) were symptom free. Increased voiding frequency, urgency, dysuria, suprapubic pain and daytime incontinence were the LUTS significantly associated with NE. Co-morbid conditions significantly associated with NE included constipation, congenital defects, developmental delay, and learning and sleep problems.

Conclusion

Although NE can be an only symptom, it is often associated with lower urinary tract symptoms like dysuria, urgency, suprapubic pain, and daytime incontinence. Children presenting with NE often have co-morbid conditions like constipation, urinary tract infection, sleep disorders, and developmental delay. Many children presenting with these conditions as the primary complaint may also have NE. It should be addressed as unrecognized and untreated NE can cause additional morbidity and distress.

     

Coronary artery thromboembolism: Unexpected presentation of left atrial myxoma covered with thrombus

Cardiac myxomas are benign primer cardiac tumors of the heart. They can be fatal with a thromboembolic presentation. Myocardial infarction is one of these unusual thromboembolic presentations. We report a patient who presented with cardiac arrest due to ventricular fibrillation related to myocardial infarction. After successful resuscitation, coronary angiography and transthoracic echocardiography were performed. A left atrial mass was observed and interpreted as a possible cause of coronary embolism leading to myocardial infarction. After surgical excision, the pathological examination confirmed myxoma, which was the essential cause of the tendency to arterial embolism.     

β-Glucan and Dark Chocolate: A Randomized Crossover Study on Short-Term Satiety and Energy Intake

Aim: The aims of this study were to adapt a traditional recipe into a healthier form by adding 3 g of oat β-glucan, substituting milk chocolate to dark chocolate with 70% cocoa, and to examine the effect of these alterations on short-term satiety and energy intake. Materials and Methods: Study subjects (n = 25) were tested in a randomized, crossover design with four products closely matched for energy content. Four different versions of a traditional recipe including milk chocolate-control (CON), oat β-glucan (B-GLU), dark chocolate (DARK) or oat β-glucan and dark chocolate (B-GLU + DARK) were given to subjects on different test days. After subjects were asked to report visual analog scale (VAS) scores on sensory outcomes and related satiety for four hours ad libitum, lunch was served and energy intake of individuals was measured. Results: VAS scores indicated that none of the test foods exerted an improved effect on satiety feelings. However, energy intake of individuals during ad libitum lunch was significantly lower in dark chocolate groups (CON: 849.46 ± 47.45 kcal versus DARK: 677.69 ± 48.45 kcal and B-GLU + DARK: 691.08 ± 47.45 kcal, p = 0.014). Conclusion: The study demonstrated that substituting dark chocolate for milk chocolate is more effective in inducing satiety during subsequent food intake in healthy subjects.
