Blood Pressure Changes in Migraine Patients before,during and after Migraine Attacks

Migraine attacks are characterized by headaches associated with neurological, gastrointestinal, and autonomic symptoms. A relationship between migraine and hypertension or hypotension is controversial. In this study, we aimed to determine if blood pressure changes were related to migraine attacks. From the outpatient clinic of our neurology department, 62 normotensive migraine patients with and without aura were chosen for study in accordance with the International Headache Society 2004 criteria. A questionnaire including general and specific questions was given to the patients to be filled out during 6 consequent migraine attacks. The patients received a fully automatic digital brachial upper arm sphygmomanometer (Omron M 4‐1) to measure the changes in their blood pressure during attacks. The patients were asked to record their blood pressure changes 3 times: (1) just before or very early, (2) during (when headache peaks), and (3) 1 hour after the attack. Twenty‐three of the 62 patients (57 women, 5 men) had migraine with aura (22 women and 1 man), and 39 of them did not have aura (35 women and 4 men). There was no statistically significant difference between systolic and diastolic values obtained before or very early, during the peak level, and 1 hour after the end of the attacks (P > 0.05). Although diastolic hypotensive values were not different statistically between groups, when all the patients were considered, diastolic hypotensive values were detected in a considerable number of patients (a total of 115 measurements). In this normotensive migrainous population, we observed that diastolic hypotension before or very early, during, and after migraine attack was the most significant result (5.1%). Although it was not statistically significant, the total number of hypotensive values was remarkable.     

Cytokine gene polymorphisms in Turkish patients with inflammatory bowel disease

OBJECTIVE: Crohn's disease (CD) and ulcerative colitis (UC) are chronic inflammatory diseases of the bowel, the causes of which are not fully known. Ethnic differences in disease prevalence, familial aggregation of the disease and studies of twins provide the most important evidence to suggest that genetic factors play a role in the pathogenesis of inflammatory bowel disease (IBD). The aim of this study was to examine the allelic polymorphisms that can determine the immune response levels in tumor necrosis factor alpha (TNFalpha), interleukin-1beta (IL-1B), interleukin-1 receptor antagonist ( IL-1RN) and interleukin-10 (IL-10) genes and to investigate their roles in the inflammatory pathway in IBD. MATERIAL AND METHODS: The study included 120 patients with UC and 70 patients with CD who were diagnosed either endoscopically or histopathologically. The control group comprised 105 healthy individuals who stated that they had never had any bowel disease during their life span. The polymerase chain reaction restriction fragment length polymorphism (PCR-RFLP) method for polymorphisms in the TNFalpha gene at positions -308 and -238, the IL-10 gene at positions -1082 and -627, the IL-1B gene at -511 regions and the variable number of tandem repeat (VNTR) method for polymorphism in the intron 2 of the IL-1RN gene were performed. The results were analyzed on agarose gel electrophoresis. RESULTS: No significant differences were found in the allele and genotype frequencies of the polymorphisms in the IL-1B, IL10, TNFalpha and IL-1RN genes between the patients with UC and CD and controls. CONCLUSIONS: The results suggest that these polymorphisms were not important risk factors in the susceptibility to IBD in Turkish patients.     

Effects of estrogen-only therapy on LDL oxidation in women with hysterectomy: Does paraoxonase genotype play a role?

OBJECTIVES: This study investigated the effects of estrogen-only therapy on lipid profile (through susceptibility of low density lipoproteins to oxidation) and on oxidant-antioxidant parameters in surgical menopausal women. PON genotypes are also evaluated considering that they may be associated with the personal differences observed in antioxidant effects induced by estrogen. METHODS: Thirty women who had undergone hysterectomy+bilateral ovariectomy in the last 3 years, with causes other than malignancy were included and given estrogen-only (Premarin-Wyeth Inc. 0.625 mg/day/6 months, equine conjugated estrogen). Blood samples were collected at baseline, first and sixth month of treatment. Serum (total antioxidant activity-TAO and PON activity), erythrocyte (TBARS and catalase activity), LDL and Cu2+ induced ox-LDL (TBARS and diene levels) samples were evaluated and PON1 192 polymorphisms were determined by PCR amplification & restriction enzyme digestion. RESULTS: At the sixth month, a higher TAO activity (p=0.016) and a lower eTBARS (p=0.028) were detected compared to the basal values. LDL and Cu induced ox-LDL TBARS levels at the sixth month of treatment were significantly (p=0.012 and 0.026, respectively) lower compared to the pretreatment values. Baseline eTBARS (p=0.007), LDL TBARS (p=0.044) and eCAT (p=0.033) activities were significantly higher in homozygote Q allele carriers compared to subjects with R allele. LDL TBARS and Cu2+ induced ox-LDLTBARS of QQ subjects (p=0.018 and 0.050) as well as LDL TBARS of QR subjects (p=0.044) showed a significant decrease with estrogen-only treatment. CONCLUSIONS: Our study drives the attention to PON polymorphism in postmenopausal women who have risk for atherosclerosis. Although our data is limited, this study is the first that focuses on the role of PON genotypes in antiatherosclerotic effects of estrogen-only and provides important points for further studies.     

Left–right asymmetry in neck lymph nodes distribution in patients with bilateral laryngeal cancer

Objective

We aimed to examine left–right asymmetry in involved and total neck lymph nodes distribution in patients with bilateral laryngeal cancer in the present study.

Methods

Forty-six patients with bilateral laryngeal cancer was included the study. The oncologic database of our otorhinolaryngology department was used. The right and left lymph node with and without involvement by cancer cells counts were retrieved from pathological reports.

Results

The numbers of both involved and total neck lymph nodes were significantly higher on right side than on left side for all neck levels in laryngeal malignancies.

Conclusions

The results of the present study suggest the existence of a left–right asymmetry in neck lymph node distribution and in the neck lymph node distribution involved by laryngeal cancer cells. The stronger cell-mediated immune activity in the left side of humans may be associated with the blocking of the metastatic invasion of cancer cells from laryngeal malignancies in the left body side.     

The association between trans fatty acids,infertility and fetal life: a review

Trans fatty acids (TFAs) are thought to affect reproductive health by causing adverse effects on sperm morphology and ovum quality as a result of changing membrane lipid composition which, in turn, leads to impairment in metabolic pathways. This literature review examines the evidence for the effects of dietary TFAs on male and female infertility. Studies conducted between 2007 and 2017 on the effect of dietary TFAs on human reproductive health and fetal life have been included. They indicate that TFA intakes are inversely proportional to sperm concentration and total sperm count and exhibit a positive correlation with asthenospermia, as well as an adverse association on sperm concentration and semen quality. In the female TFAs intakes are associated with an increase in the risk of ovulatory infertility, adversely affect the length of gestation leading to fetal developmental defects and fetal loss. The findings suggest that high TFA intake (more than 1% of energy consumption) constitute a risk factor for infertility in both sexes.

Anterior urethral valves: an uncommon cause of obstructive uropathy in children

PurposeAnterior urethral valves (AUV) are rare entities generally described in case reports. They are an uncommon cause of lower urinary tract obstruction in children and can be difficult to diagnose. In the present study, we present our experience in four children with AUV along with a literature review.Materials and methodsWe retrospectively identified four children with AUV presented between 1998 and 2005 at age 4–9 years.ResultsHematuria, urinary tract infection and weak voiding stream were the most common symptoms. Voiding cystourethrography (VCUG) confirmed the diagnosis of AUV. On cystourethroscopy, cusp-like valves in the anterior urethra were seen in all children. Transurethral endoscopic resection of the valves was carried out in three children using a pediatric resectoscope. In one child with a massive anterior urethral diverticulum, open resection of the valve, diverticulectomy and urethroplasty were performed. All patients were cured, none had complications as a result of surgery, and all reported a normal urinary stream at follow-up.ConclusionsChildren with poor stream and recurrent infections should be evaluated carefully and anterior urethral valves should be considered in differential diagnosis of obstructive lesions.
