Prevalence of hepatitis B virus infection in pregnant Turkish women and their families

A total of 5,366 pregnant Turkish women were screened for hepatitis B surface antigen (HBsAg) and 225 (4.2%) of them were found to be positive. Hepatitis B e antigen (HBeAg) was detected in 6.2% of HBsAg-positive pregnant women. The overall prevalence of HBsAg and antibody to HBsAg (anti-HBs) among the spouses, previous children, mothers and first degree relatives of the HBsAg-positive pregnant women was 56%, 49%, 79% and 74% respectively. The prevalence of HBsAg is thus high in pregnant Turkish women with familial clustering of hepatitis B virus infection.     

The Relation between the Color M‐Mode Propagation Velocity of the Descending Aorta and Coronary and Carotid Atherosclerosis and Flow‐Mediated Dilatation

Background: To improve clinical outcomes, noninvasive imaging modalities have been proposed to measure and monitor atherosclerosis. Common carotid intima‐media thickness (CIMT) and brachial artery flow‐mediated dilatation (FMD) have correlated with coronary atherosclerosis. Recently, the color M‐mode‐derived propagation velocity of descending thoracic aorta (AVP) was shown to be associated with coronary artery disease (CAD). Methods: CIMT, FMD, and AVP were measured in 92 patients with CAD and 70 patients having normal coronary arteries (NCA) detected by coronary angiography. Patients with acute myocardial infarction, renal failure or hepatic failure, aneurysm of aorta, severe valvular heart disease, left ventricular ejection fraction <40%, atrial fibrillation, frequent premature beats, left bundle branch block, and inadequate echocardiographic image quality were excluded. Results: Compared to patients with normal coronary arteries, patients having CAD had significantly lower AVP (29.9 ± 8.1 vs. 47.5 ± 16.8 cm/sec, P < 0.001) and FMD (5.3 ± 1.9 vs. 11.4 ± 5.8%, P < 0.001) and higher CIMT (0.94 ± 0.05 vs. 0.83 ± 0.14 mm, P < 0.001) measurements. There were significant correlations between AVP and CIMT (r =−0.691, P < 0.001), AVP and FMD (r = 0.514, P < 0.001) and FMD and CIMT (r =−0.530, P < 0.001). Conclusions: The transthoracic echocardiographic determination of the color M‐mode propagation velocity of the descending aorta is a simple practical method and correlates well with the presence of carotid and coronary atherosclerosis and brachial endothelial function.

Cystic hygroma and lymphangioma: associated findings,perinatal outcome and prognostic factors in live-born infants

Objectives We aimed to determine associated ultrasonographic findings, chromosome abnormalities and the prognostic factors of cystic hygromas in live-born infants. Methods We reported a series of 57 cystic hygroma cases, who were diagnosed in the first and the second trimester of pregnancy by means of the ultrasonographic morphology of cystic hygroma, associated structural abnormalities, karyotype analysis and the autopsy findings. Survivors were followed for their fetal outcome and prognosis. Results There were 57 new cases of cystic hygroma among 8,155 screenings (0.7%). 35 of the cases (61.4%) were nonseptated and 22 of the cases (38.6%) were septated cystic hygroma. Chromosomal abnormalities were found in 23 of the cases (40.3%). The most common abnormality in nonseptated cystic hygroma was trisomy 21 (8 cases, 25%) and in septated cystic hygroma was Turner syndrome (4 cases, 21.1%). The most common associated structural malformations were cardiac abnormalities (in 7 cases, 20%) in nonseptated cystic hygroma cases and nonimmune hydrops (in 12 cases, 54.5%) in septated cystic hygroma cases. Overall survival was poor; only one case of septated cystic hygroma with axillary location and seven cases of nonseptated cystic hygroma, of whom two died in the neonatal period, were alive (10.5%). This study had 80% power to detect 0.03% difference in diagnosis cystic hygroma (α = 0.05, β = 0.80). Conclusion Fetuses with cystic hygroma are at high risk for adverse outcome. Prenatal diagnosis with invasive procedures should be done in order to inform the parents in detail. Axillary location of the hygroma and the depth of invasion had prognostic importance.     

Cross-resistance and associated resistance in <Emphasis Type="Italic">Escherichia coli</Emphasis> isolates from nosocomial urinary tract infections between 2004–2006 in a Turkish Hospital

In this study, antimicrobial resistance profiles were determined for 748 isolates of Escherichia coli from patients with acute nosocomial urinary tract infections (UTIs) at a Turkish Training Hospital. Thirteen antibiotics were included. Resistance to ampicillin alone (45.1%) and ciprofloxacin alone (20.6%) were the most commonly identified ‘single resistances’. Multiple resistance was found in 49.7% of the strains. The most common multiple antibiotic resistance profiles included ampicillin-sulbactam/amoxycilline-clavulonate (4.0%) and ampicillin-sulbactam/trimethoprim-sulfamethoxazole/amoxycilline-clavulonate (2.8%). From 2004 to 2006, ampicillin, trimethoprim-sulfamethoxazole and ciprofloxacin resistant strains increased to 76% from 57%, 53% from 43% and 55% from 41%, respectively. The percentage of extended-spectrum β-lactamase (ESBL) producing strains was 7.8% and imipenem resistance was seen in 5.2% of ESBL positive strains. We conclude that clinically important E.coli strains have now emerged with broader multidrug resistance. Periodical evaluation of laboratory results and clinical surveillance are crucially important for optimal antibiotic management of UTIs and infection control policies.     

Psychological distress in chronic obstructive pulmonary disease patients

Stress is defined as the exposure of an individual to a threatening stimulus or overwhelming event. Increased rates of psychological distress have been established in patients with chronic diseases compared to healthy individuals. The objective of the present study is to assess the indicators and correlates of psychological distress in chronic obstructive pulmonary disease (COPD) patients. We evaluated the stress exposure (stressful events that COPD patients and control subjects had been exposed) by a life events checklist and psychological distress by General Health Questionnaire in 74 COPD patients and 30 control subjects. Serum adrenocorticotropic hormone (ACTH) and cortisol levels were measured as biochemical indicators of stress. Distress score was higher in COPD group compared to age‐matched controls, although the stress exposure score were not statistically different; indicating that COPD itself is a source of distress. 92% of COPD patients and 87% of control subjects had varying degrees of distress. Severe distress was more frequent in COPD group. Distress score was further increased in patients with severe COPD and severe hypoxemia.There was no significant difference in serum ACTH and cortisol levels of COPD patients and control subjects and distress scores were not correlated to serum ACTH and cortisol levels. However, serum cortisol was higher in patients with severe hypoxemia. These findings support the importance of screening for psychological distress symptoms in COPD outpatients. Since high degree of distress contributes to impaired quality of life and added morbidity, patients with COPD need a comprehensive care including a psychological evaluation.

Multiple sclerosis and coexisting intradural extramedullary spinal cord tumour: a case report

We report the coexistence of multiple sclerosis (MS) and an intradural extramedullary spinal cord tumour in a 46-year-old woman with a 2-year history of MS. The patient presented with right hemitrunk and lower extremity paraesthesias, urinary incontinence, and intermittent lower right back and abdominal pain, which did not respond to pulse steroid therapy. A spinal magnetic resonance imaging (MRI) study revealed an intradural extramedullary spinal cord tumour in the lower thoracic spine, later diagnosed as schwannoma. We call attention to this rare association of MS and a spinal cord tumour, and emphasize the need for scrutiny of new and uncommon symptoms during the follow-up of MS patients.

Successful intrauterine treatment with alcohol ablation in a case of acardiac twin pregnancy.

Acardiac twinning is a rare obstetric condition unique to monochorionic twin gestation and the pump twin has high perinatal mortality. We report an acardiac twin pregnancy, in which the pump twin presented with intrauterine growth restriction and oligohydramnios, and grossly hydropic acardiac fetus measured 12 x 14 x 18 cm, and with no cardiac activity at 27 weeks of gestation. We treated the acardiac fetus with 1 ml alcohol ablation in utero, and delivered a live male baby weighing 1750 g at 36 weeks' gestation.     

Effect of indapamide on urinary calcium excretion in patients with and without urinary stone disease

BACKGROUND: Indapamide is an antihypertensive agent similar to thiazides, but with some different effects. Thiazide and thiazide-like diuretics are useful in preventing recurrent urinary stone formation due to their hypocalciuric effects. OBJECTIVE: To determine the hypocalciuric and other effects on certain laboratory parameters of indapamide 1.5 mg in different patient groups. METHODS: Four groups of patients recruited from urology and nephrology outpatient departments were experiencing non-hypercalciuric urinary stone disease (group 1), idiopathic hypercalciuria (group 2), urinary stone disease with hypercalciuria (group 3), and essential hypertension (group 4). In all patients, fasting serum uric acid, calcium, sodium, potassium, cholesterol, triglyceride, parathyroid hormone (PTH) values, and morning second-spot urine calcium and creatinine levels were assessed before and 8 weeks after treatment with indapamide. RESULTS: Urinary calcium excretion was reduced significantly in all groups: group 1 from 0.10 +/- 0.02 to 0.07 +/- 0.03 (mean +/-SD; 30% reduction; p < 0.001), group 2 from 0.30 +/- 0.15 to 0.15 +/- 0.10 (50% reduction; p < 0.001), group 3 from 0.35 +/- 0.15 to 0.20 +/- 0.10 (43% reduction; p < 0.001), and group 4 from 0.10 +/- 0.03 to 0.08 +/- 0.02 (20% reduction; p < 0.0010). These results should be interpreted with caution since no control group was included in this study. Mean serum uric acid and triglyceride levels were significantly increased, and mean PTH and potassium levels and diastolic and systolic blood pressure were significantly decreased in all groups. Few temporary adverse effects, such as dizziness and fatigue, were noticed and none of them caused discontinuation of treatment. CONCLUSIONS: Indapamide 1.5 mg/day is effective in decreasing calciuria in patients with non-hypercalciuric urinary stone disease, idiopathic hypercalciuria, urinary stone disease with hypercalciuria, and essential hypertension. This could be achieved with few adverse effects similar to those of thiazides and indapamide 2.5 mg. Indapamide decreased the PTH levels in all groups. Long-term clinical benefits of these effects should be evaluated prospectively with further randomized studies.
