Do energy drinks cause epileptic seizure and ischemic stroke?

Energy drinks are popular among young individuals and marketed to college students, athletes, and active individuals between the ages of 21 and 35 years. We report a case that had ischemic stroke and epileptic seizure after intake of energy drink with alcohol. To the best of our knowledge, the following case is the first report of ischemic stroke after intake of energy drink. A previously healthy 37-year-old man was brought to the emergency department after a witnessed tonic-clonic seizure. According to his wife's testimony, just before loss of consciousness, the patient had been drinking 3 boxes of energy drinks (Redbull, Istanbul, Turkey, 250 mL) with vodka on an empty stomach. He did not have a history of seizures, head trauma, or family history of seizures or another disease. In cranial diffusion magnetic resonance imaging, there were hyperintense signal changes in bilateral occipital area (more pronounced in the left occipital lobe), right temporal lobe, frontal lobe, and posterior parietal lobe. All tests associated with possible etiologic causes of ischemic stroke in young patients were negative. Herein, we want to attract attention to adverse effect of energy drink usage.

The evaluation of atherosclerosis in migraine patients.

A potential association might exist between atherosclerosis and migraine. Carotid intima-media thickness (CIMT) is a marker of generalized atherosclerosis; hence, we aimed to assess CIMT in migraine patients. This study included 30 patients and 60 healthy controls aged between 20 and 40 years. Episodic migraine diagnosis was made according to the criteria of International Headache Society (IHS). Healthy controls who do not suffer any headache problems were selected from among hospital and laboratory staffs. All subjects were evaluated regarding some parameters and features known to be associated with migraine and vascular changes, that is, gender, age, body mass index, blood pressure, cholesterol, smoking habits, used hormonal contraceptives, and history of disease. The left common carotid arteries of the subjects were examined, and CIMT was measured with real-time gray-scale sonography. Mean values and standard deviations were calculated. All measurements were made in migraine-free periods. Migraine patients and control subjects were well matched for those parameters known to be associated with vascular changes, that is, gender, age, BMI, blood pressure, and cholesterol. CIMT values were higher in patients. The results showed that the mean CCA IMT values were 0.493 ± 0.074 mm and 0.409 ± 0.053 mm in migraine patients and controls, respectively (P < 0.001). There is a relationship between atherosclerosis and inflammation in migraine patients. The risk of cranial inflammatory arteriopathy increases in repeated attacks of migraine. Our study also supports that high number of attacks and attack duration are important in the development of atherosclerosis.

[Evaluation of carotis intima media thickness in chronic obstructive pulmonary disease patients]. / Kronik obstrüktif akciger hastaliginda karotis intima mediya kalinliginin degerlendirilmesi.

INTRODUCTION: Chronic obstructive pulmonary disease (COPD) and atherosclerosis may occur due to similar risk factors and have a significant cause of morbidity and mortality. In this study to assess the relationship between COPD and atherosclerosis; carotid intima media thickness (CIMT) of COPD patients and adult healthy individuals with normal body mass index and metabolic parameters compared. MATERIALS AND METHODS: 2298 participants aged between 18-92; 46 patients diagnosed with COPD according to clinical features and pulmonary function tests the study, 47 healthy controls who do not have exclusion criteria were evaluated. Doppler ultrasound was performed for the assessment of CIMT to all participants. p values < 0.05 were considered to be significant. RESULTS: Mean CIMT in COPD group and control group were 0.79 ± 0.16 mm and 0.616 ± 0.1 mm, respectively (p< 0.001). In multiple linear regression analysis that made to determine the atherosclerotic risk parameters affecting CIMT; it was found that CIMT was related to age with direct proportion (p= 0.002) and to FEV(1)% with inversely proportion (p= 0.04). In multivariate logistic regression analysis that made to determine the parameters affecting atherosclerosis; we found that any parameters were related with atherosclerosis. CONCLUSION: Persistent low-grade systemic inflammation in COPD and atherosclerotic disease may possibly have been reported a factor in both pathologies. Early atherosclerosis and cardiovascular risks in adults with COPD increase independent of risk factors. CIMT which shows direct proportion with age and inverse proportion with FEV(1)% is a non-invasive, easily applicable and cheap method that can be used in determining the risk of atherosclerosis.

Carotid intima media thickness and cardiometabolic risk associates in Turkish adults.

OBJECTIVE: Carotid intima media thickness (CIMT) is a strong predictor of future vascular events. However, data for Turkish individuals are limited and the association between cardiometabolic risk factors and CIMT has not been studied before.Therefore, we sought to investigate the CIMT and cardiometabolic risk associates in a large cohort of Turkish adults. METHODS AND RESULTS: The study was conducted on 2230 participants (1427 women, 803 men with a mean age of 49). The participants underwent a Doppler Ultrasound examination of CIMT. Mean CIMT was 0.61 +/- 0.19 mm. Age- and sex-adjusted partial correlation analysis revealed that only systolic blood pressure and smoking amount was significantly correlated with CIMT. Receiver operator characteristics (ROC) calculations showed that age had the best area under the curve (AUC = 0.84), smoking had the best sensitivity (86%) and diastolic blood pressure (> 88 mmHg) had the best specificity (74%) in predicting a person with thickened carotid intima media (> 0.8 mm). Independent predictors of thickened carotid intima media were hypertension [(odds ratio (OR) = 2.74; 95% confidence interval (CI) = 1.663-4.53; P value < or = 0.001)], systolic blood pressure [OR = 1.01; 95% CI = 1.002-1.022; P value = 0.022] and age [OR = 1.11; 95% CI = 1.079-1.136; P value < or = 0.001). CONCLUSION: Age, systolic blood pressure and smoking amount (pack/year) were the only age- and sex-adjusted associates of CIMT. Age had the best AUC in ROC analysis predicting thickened carotid artery intima media. Hypertension, systolic blood pressure and age were independent predictors of high CIMT in Turkish adults.

Unilateral isolated abducens nerve paralysis: an unexpected complication of frontal mucocele.

Although paranasal sinus mucoceles are benign lesions, they are important because of the destruction they form in the bone structure in sinus wall. They are observed most frequently in frontal sinus; especially at this location, they may cause serious pathologic lesions in the neighboring structures as the orbit and cranium. Paranasal sinus mucoceles can be treated with open or closed endoscopic surgical methods. In this article, we present an unexpected complication of frontal mucocele, abducens nerve paralysis, and its treatment.

Life-threatening angiomyxoma of the larynx.

BACKGROUND: Angiomyxoma is a benign proliferative mesenchymal tumor and a very rare mass in the larynx. There is not enough information about the etiology, clinical finding, treatment and prognosis of laryngeal angiomyxoma. CASE DETAILS: A 52 years old man presented with respiratory distress. Also, he had suffered from dysphagia, dysphonia, cough, and obstructive sleep apnea in the supine position for 6 months. He was operated on via transoral approach under general anesthesia with orotracheal intubation. The mass was encapsulated and completely removed. The histopathologic diagnosis was reported as angiomyxoma. CONCLUSION: Angiomyxoma should be considered in the differential diagnosis of the larynx masses. The treatment of angiomyxomas of the larynx is surgical. The mass can be usually excised intraorally or endoscopically.

Color Doppler Imaging of the Orbital Vessels in Ankylosing Spondylitis.

PURPOSE: To analyze the hemodynamic features of orbital blood flow velocities using Doppler ultrasonography in ankylosing spondiylitis (AS) patients, as well as to compare these results with those of healthy controls. METHODS: 33 AS patients and 32 healthy controls were consecutively included in the study groups. The same radiologist performed ocular blood flow measurements. Peak systolic velocity (PSV), end diastolic velocity (EDV), and resistive index (RI) were measured in the central retinal artery (CRA), posterior ciliary arteries (PCAs), and ophthalmic artery (OA). Resistive index was used to assess arterial resistance; it was automatically calculated as RI [(PSV-EDV)/PSV]. RESULTS: There were no significant differences in the PSV, EDV, and RI of the OA, CRA, and PCAs between AS patients and controls. CONCLUSION: This result suggests no possible contributory role of vascular structures in formation of uveitis in AS. We believe that our preliminary results need to be complemented with further studies, particularly including AS patients with uveitis and rheumatic diseases with other ocular involvement.

Minimally invasive treatment of giant haemangiomas of the liver: embolisation with bleomycin.

PURPOSE: The management of patients with giant haemangioma of the liver remains controversial. Although the usual treatment method for symptomatic giant haemangioma is surgery, the classical paradigm of operative resection remains. In this study, we evaluated the symptomatic improvement and size-reduction effect of embolisation with bleomycin mixed with lipiodol for the treatment of symptomatic giant hepatic haemangioma. METHODS: This study included 26 patients [21 female, five male; age 41-65 years (mean 49.83 ± 1.53)] with symptomatic giant haemangioma unfit for surgery and treated with selective embolisation by bleomycin mixed with lipiodol. The patients were followed-up (mean 7.4 ± 0.81 months) clinically and using imaging methods. Statistical analysis was performed using SPSS version 16.0, and p < 0.05 was considered to indicate statistical significance. RESULTS: Embolisation of 32 lesions in 26 patients was performed. The mean volume of the haemangiomas was 446.28 ± 88 cm(3) (range 3.39-1559 cm(3)) before intervention and 244.43 ± 54.38 cm(3) (range 94-967 cm(3)) after intervention. No mortality or morbidity related to the treatment was identified. Symptomatic improvement was observed in all patients, and significant volume reduction was achieved (p = 0.001). CONCLUSION: The morbidity of surgical treatment in patients with giant liver hemangioma were similar to those obtained in patients followed-up without treatment. Therefore, follow-up without treatment is preferred in most patients. Thus, minimally invasive embolisation is an alternative and effective treatment for giant symptomatic haemangioma of the liver.

Giant myoepithelioma of the soft palate.

Myoepitheliomas are benign salivary gland tumors and account for less than 1% of all salivary gland tumors. They are usually located in the parotid gland. The soft palate is very rare affected site. The differential diagnosis of myoepitheliomas should include reactive and neoplastic lesions. The treatment of myoepitheliomas is complete removal of the tumor. Herein, we report a case with giant myoepithelioma of the soft palate, reviewing the related literature.

Hormone replacement therapy-related changes in the early postmenopausal period (critical window): an in vivo brain proton magnetic resonance spectroscopy study.

AIM: Findings from clinical studies in postmenopausal women with late initiation of hormone replacement therapy (HRT) that test whether HRT protects cognitive functions in women are inconsistent. The aim of this study was to investigate the effects of HRT on brain metabolite ratios when initiated in the early postmenopausal period (critical window). MATERIALS AND METHODS: Proton magnetic resonance spectrometry (1H MRS) was performed in 4 brain regions of 47 healthy postmenopausal women (21 received HRT, 26 did not). The subjects were aged between 45 and 65 years. The duration of HRT ranged from 1 to 12 years (mean: 6.3 years). The duration of menopause was 2-12 years (mean: 6.1 years) for HRT users and 1-20 years (mean: 7.8 years) for non-HRT users. Metabolite ratios [N-acetyl aspartate/choline (NAA/Cho), NAA/creatine (Cr), and Cho/Cr] were evaluated. RESULTS: Cho/Cr ratios were significantly increased and NAA/Cho ratios significantly decreased in all 4 regions in the HRT user group compared to the other group after elimination of the effects of age and menopause duration. Regression analysis revealed an association only between NAA/Cho and duration of menopause. CONCLUSION: HRT-related changes in metabolite ratios are found in all brain regions. Decreased NAA/Cho and increased Cho/Cr levels do not support the neuroprotective role of HRT in the critical window.

Dual diagnosis: rheumatoid arthritis and multiple sclerosis.

Juvenile rheumatoid arthritis (JRA) is the most common rheumatologic disease in children. Moreover, multiple sclerosis (MS) is the most frequent demyelinating disease and has been associated with various chronic inflammatory diseases. However, its association with JRA has not been frequently described. Autoimmunity in both JRA and MS has been documented in the scientific literature, although there has been no definitive finding that patients with JRA are prone to the development of MS. An increasing frequency of MS resulting from an increased use of antitumor necrosis factor agents in the treatment of rheumatoid arthritis and other chronic inflammatory diseases has been reported recently. In this study, we report on the development of MS in a patient with JRA who did not have a history of antitumor necrosis factor use.

Relation between radiographic BI-RADS scores and triple negativity in patients with ductal carcinomas.

UNLABELLED: The aim of this study was to investigate association of radiographic (BI-RADS 4 and 5) results and prognostic factors of invasive ductal carcinomas with their histopathological subtypes. A total of 103 patients histopathologically diagnosed with invasive ductal carcinoma of breast with in last five years period were enrolled. Of them, 69 patients who had radiological reports in were included from registry of Radiology Department; Duzce University Training and Research Hospital archives. BI-RADS scores (4 and 5) of radiological reports and subtypes of ductal carcinoma were compared. Of 69 cases, 12 of 22 cases with BIRADS 4 score were Triple negative (TN) while 5 of 47 cases with BIRADS 5 score were TN (p = 0.001). The patients with TN tumors were found to have lower average age, higher grade, higher Ki67 proliferative index and fewer lymph node metastasis than those with non-TN ductal carcinomas (p = 0.048; 0.019; 0.02; 0.048 respectively). CONCLUSIONS: Patients who had radiological BIRADS 4 score were significantly more frequent TN type carcinoma than BI-RADS 5. It is important to pay attention to this issue when clinicians evaluate patients with BI-RADS 4 score breast lesions.

Spectrum and prevalence of nodular thyroid diseases detected by ultrasonography in the Western Black Sea region of Turkey.

OBJECTIVE: The aim of the study was to investigate thyroid diseases and the prevalence of goiter by ultrasonography (US) in a moderately iodine deficient area. MATERIAL-METHODS: The MELEN Study is a prospective cohort study on the prevalence of thyroid diseases in Turkish adults. A total of 2233 subjects with a mean age of 50 (age range 18 to 92) were submitted to study. Thyroid US was performed and interpreted by the same experienced physician. Goiter prevalence was defined according to Gutekunst's criteria. RESULTS: The most common thyroid disease was multinodular goiter (MNG) (42%), followed by nodular goiter (NG) (14.6%). The crude prevalence of nodular disease in the region was 56.6%. In the study cohort, thyrotoxicosis (TSH <0.35 µIU/ml) prevalence was 12 % and subclinical and overt hypothyroidism (TSH > 4.5 µIU/ml) prevalence was 6.5 %. CONCLUSION: We found that thyrotoxicosis and nodular thyroidal diseases are more important public health issues in moderate iodine deficient geographical areas. We recommend the increased rates of US screening especially in the endemic regions in order to detect thyroidal nodules earlier.

May headache be the first sign of mutation in the MTHFR gene?

BACKGROUND: Cerebral venous thrombosis (CVT) is a rare disease and it has different etiologies. Inherited or acquired prothrombotic state plays a key role in the development of CVT. METHODS: A 28-year-old man who presented to our emergency department with persistent headache and accompanied by complaints of nausea and vomiting over a week. Neurologic examination revealed bilateral papilledema. Brain computed tomography showed a hyperdense area on the posterior part of the occipital lobe. Brain magnetic resonance imaging and magnetic resonance venography revealed thrombosis of CVT. Homozygous mutations were found for methylenetetrahydrofolate reductase (MTHFR). MTHFR CG677T gene mutation and blood tests showed elevated homocysteine levels on the etiological screening. There was no other etiology for CVT. RESULTS: Headache and other complaints were improved after treatment of heparin, warfarin, and vitamin B12. No recurrence of symptoms was observed upon outpatient follow-up. CONCLUSION: Since CVT is an important cause of headache, we recommend etiology screening for patients who present with CVT for MTHFR gene mutations and family counseling should be provided.

The prevalence of fibromyalgia among patients with hepatitis B virus infection.

Fibromyalgia (FM) is a syndrome characterized by widespread and chronic musculoskeletal pain, fatigue, morning stiffness, and sleep disturbance. However, the etiopathogenesis of FM remains unclear. Various etiological factors have been suggested to trigger FM. These include systemic rheumatismal disease, physical trauma, psychological disorders, and chronic infections. We determined the prevalence of FM in patients with chronic active hepatitis B virus (HBV) and inactive hepatitis B carriers, compared with matched healthy controls. Seventy-seven HBV patients (39 HBV carriers and 38 with chronic active hepatitis), were evaluated for FM syndrome. Seventy-seven HBsAg-negative healthy subjects were enrolled as a control group. We found that FM was very prevalent in patients with HBV infections (22% of the total). We found no difference in FM prevalence when patients with chronic active hepatitis B infections (21% FM prevalence) and those who were inactive hepatitis B carriers (23% FM prevalence) were compared. FM was not associated with the levels of HBV-DNA, ALT, or AST. Recognition and management of FM in HBsAg-positive patients will aid in improvement of quality-of-life. We fully accept that our preliminary results require confirmation in studies including larger numbers of patients. More work is needed to allow us to understand the role played by, and the relevance of, infections (including HBV) in FM syndrome pathogenesis.

The benefit of expiratory-phase quantitative CT densitometry in the early diagnosis of chronic obstructive pulmonary disease.

PURPOSE: We aimed to compare the inspiratory and expiratory quantitative computed tomography (CT) densitometric data of healthy volunteers, individuals with chronic obstructive pulmonary disease (COPD) risk, and COPD patients to aid in the early diagnosis of COPD. MATERIALS AND METHODS: Of the study patients, 14 were healthy volunteers (Group I), 12 were patients at risk for COPD (Group II), and 13 were COPD patients (Group III). The high-resolution CT was performed at three levels (the upper, middle, and lower parts of the lungs). All images were evaluated with a specific program for the segmentation of pulmonary parenchyma. The mean lung density (MLD) was measured, and the emphysema index (EI) was calculated using this program. RESULTS: Both MLD values and calculated EI ratios showed significant differences between Groups I and III, and Groups II and III in both expiratory and inspiratory phases (P < 0.05). However, in the comparison of healthy volunteers and patients at risk for COPD (Group I and II), only expiratory-phase MLD values showed statistically significant difference (P < 0.001). CONCLUSION: In patients at risk for COPD, expiratory-phase MLD measurements can be used as an early diagnostic method.

[Normal value correlates of carotid intima- media thickness and affecting parameters in healthy adults]. / Saglikli eriskinlerde karotis intima-media kalinliginin normal degerleri ve etkileyen parametreler.

OBJECTIVE: Early changes in atherosclerosis can be diagnosed by the carotid artery intima-media thickness (CIMT) measurement. Normal range of CIMT in healthy subjects has not been studied yet in our country. Therefore, the aim of this study was to measure the CIMT in healthy individuals and investigate affecting parameters of CIMT. METHODS: Overall, 2298 subjects, aged 18 to 92 years were undergone CIMT measurement in this observational cohort study. 151 healthy adult subjects, aged 20 to 79 year without atherosclerotic risk factors, normal body mass index and normal metabolic parameters were selected to establish normative CIMT values. Correlations between CIMT and atherosclerotic risk factors were evaluated in the Turkish population. The independent variables associated with CIMT were evaluated with multiple linear regression analysis. RESULTS: CIMT value was 0.458 ± 0.116 mm in males and 0.47 ± 0.104 mm in females. Mean values of CIMT (in mm) for healthy reference sample aged 20-29, 30-39, 40-49, 50-59, 60-69 and 70-79 years were 0.402; 0.466; 0.492; 0.586; 0.692 and 0.733, respectively. CIMT increased significantly (p<0.001) by 0.066 mm, in every decade. Correlates of CIMT were age, visceral fat level, fasting serum glucose, total and low-density lipoprotein cholesterol. Multiple linear regression analysis revealed that age was the single independent predictor of CIMT thickness in healthy individuals (ß=0.007, 95% CI: 0.006-0.008, p<0.001). CONCLUSION: CIMT was 0.458 ± 0.116 mm in men and 0.47 ± 0.104 mm in Turkish healthy adults. Age was the only predictor of CIMT. CIMT measurement can be used in the assessment of early atherosclerosis burden in adults.

Enoxaparin-associated giant retroperitoneal hematoma in pulmonary embolism treatment.

CONTEXT: Retroperitoneal hematoma may usually occur as a result of trauma. A life threatening retroperitoneal hematoma is not expected complication of anticoagulation treatment and rarely reported. Low molecular weight heparins (Enoxaparin) which are used as effective and safe medicine in the venous thromboemboly treatment have some major complications such as hematomas of different organs. We aim to present a giant spontaneous retroperitoneal hematoma after anticoagulant treatment of pulmonary embolism with enoxaparin. CASE REPORT: A 73-year-old male patient with the diagnosis of pulmonary embolism underwent anticoagulant treatment (enoxaparin). In the second day of admission, the patient had an episode of abdominal and back pain. Abdominal ultrasonography and computerized tomographic scan revealed a giant retroperitoneal hematoma. Enoxaparin treatment was then stopped and the supportive treatment was started. In the following days, hemoglobin levels returned to normal and a control CT revealed regression of hematoma size. CONCLUSION: The anticoagulant treatment with enoxaparin may lead to severe hematomas. Therefore, the clinical suspicion is required especially in elderly patients and patients with impaired renal function for retroperitoneal hematoma, when they suffer from acute abdominal pain.
