Evaluation of the risk factors for acute occupational hand injuries

OBJECTIVES

To evaluate the effect of demographic and occupational factors on the severity of the acute occupational hand injuries.

METHODS

Patients with acute hand injuries presenting to the emergency department of the Ege university hospital between 01.08.2008 and 27.02.2009 were included. A questionnaire investigating demographic and occupational factors of the patients and their injuries was filled out for each patient. Modified Hand Injury Severity Score (MHISS) was used to assess the severity of the injury.

RESULTS

A total of 144 subjects were included. Forty-three patients had occupational hand injuries. Age at injury, occupation, and main earning status did not alter the MHISS score significantly. Also, the mechanism of injury, occupational experience, timing of the injury, glove use, safety training did not have a significant effect on the injury severity. The injury pattern was found to have a statistically significant effect on the MHISS score.

CONCLUSION

The potentially modifiable factors such as the working conditions, safety training and use of gloves are important in the etiology of occupational acute hand injury. Most probably, in this study the size of the sample was not large enough to be able to demonstrate any relation between these and the injury severity. However, attempts to modify these factors by various strategies may reduce the incidence of acute hand injury at work. Precautions and widespread educational programs can prevent occupational acute hand injury.

Retina evokes biphasic relaxations in retinal artery unrelated to endothelium, K(V), K(ATP), K(Ca) channels and methyl palmitate

Retinal relaxing factor (RRF) is suggested to be released from the retina and to contribute in the maintenance of retinal arterial tone. Herein, we aimed to clarify the effects of retinal tissue in isolated bovine retinal arteries in comparison with choroidal tissue and to evaluate the possible role of endothelium and potassium channels. In parallel, the effects of palmitic acid methyl ester (PAME), a putative vasodilator proposed to be released from the retina, was also examined. A piece of bovine retinal or choroidal tissue was placed within a close proximity on top of retinal arteries mounted in a wire myograph and precontracted with noradrenaline, prostaglandin F(2α), endothelin-1, thromboxane A(2) mimetic, U46619 or potassium (K(+)). To elucidate possible mechanisms in the effects of retinal tissue, retinal arteries were either deendothelized or incubated with inhibitors of endothelial vasodilators, i.e. nitric oxide (NO) and prostaglandins, or K(+) channels. Unlike the choroid, retinal tissue produced rapid, biphasic and complete relaxations in isolated bovine retinal arteries precontracted with various spasmogens acting on distinct receptors. Endothelium removal or preincubation of retinal arteries with inhibitors of NO synthase; L-NOARG (10(-4)M), guanylate cyclase; ODQ (10(-5)M) and cyclooxygenase; indomethacin (10(-5)M), did not cause a significant difference in the relaxation profile. Additionally, retinal relaxations remained unchanged in the presence of respective inhibitors of ATP-sensitive (K(ATP)) (glibenclamide, 10(-5)M), voltage-dependent (K(V)) (4-aminopyridine, 2×10(-3)M), and calcium-activated (K(Ca)) (tetraethylammonium 10mM; charybdotoxin, 10(-7)M; and apamin, 5×10(-7)M) K(+) channels. Thus, our results provide novel evidence regarding the biphasic relaxing profile of RRF in the retinal artery which was unrelated to endothelium and K(+) channels (K(ATP), K(V) and K(Ca)). Interestingly, PAME (10(-14)-10(-5)M) did not provoke a relaxation in bovine retinal artery suggesting no association with RRF.

The comparison of aripiprazole and risperidone augmentation in selective serotonin reuptake inhibitor-refractory obsessive-compulsive disorder: a single-blind, randomised study

OBJECTIVE

To investigate the comparative efficacy of aripiprazole and risperidone as augmenting agents in the treatment of obsessive-compulsive disorder (OCD) patients who did not show a ≥35% decrease in the Yale-Brown Obsessive-Compulsive Scale (Y-BOCS) after 12-week monotherapy with selective serotonin reuptake inhibitors (SSRIs).

METHODS

The study consists of two different periods of treatment: a 12-week prospective period to determine resistance to SSRI treatment and an 8-week single-blind addition period for refractory patients only. Ninety patients were randomly assigned to receive one of the SSRI treatments. Sixty-nine patients (76.6%) completed the 12-week SSRI monotherapy period. Forty-one patients (59.4%) were considered refractory and were randomised to receive either risperidone (20 patients, 3 mgr daily) or aripiprazole (21 patients, 15 mgr daily) as augmentation to SSRI treatment. Sixteen patients (76.2%) in the aripiprazole group and 18 patients (84%) in the risperidone group completed the 8-week treatment period.

RESULTS

Eight patients (50%) in aripiprazole and 13 patients (72.2%) in risperidone group met response criteria of Y-BOCS decrease ≥35% at the end of the study. The risperidone group showed a significant improvement in Y-BOCS obsession scores compared with aripiprazole.

CONCLUSIONS

The present findings suggest that risperidone may be more effective than aripiprazole.

[Silent enemy in acute rheumatic fever: subclinical carditis]

OBJECTIVES

Routine use of Doppler echocardiography for the initial diagnosis of acute rheumatic fever (ARF) might allow early detection and, hence, prevention of rheumatic recurrences. This study sought to determine the incidence of subclinical carditis in ARF patients.

STUDY DESIGN

The study included 80 patients (64 migratory polyarthritis, 16 rheumatic chorea) who were diagnosed with ARF according to the Jones criteria, 1992 update. Rheumatic carditis was defined as the presence of the following findings on Doppler echocardiography: mitral and aortic regurgitant jets in at least two planes, the length of the jets >1 cm, and peak flow velocities of >2.5 m/sec for both mitral and aortic regurgitations persisting throughout systole and diastole, respectively. The patients diagnosed with subclinical carditis were re-evaluated at 1, 3, 6, and 12 months.

RESULTS

Echocardiography revealed subclinical carditis in 25 patients (31.3%; 13 girls, 12 boys; mean age 11.4±2.5 years) with ARF. Of 64 patients with migratory polyarthritis, 34 (53.1%) had clinical carditis and 17 (26.6%) had subclinical carditis. The incidences of clinical and subclinical carditis among 16 patients with rheumatic chorea were 31.3% (n=5) and 50% (n=8), respectively. Of 20 patients who completed one-year follow-up, persistence of subclinical carditis was observed in 11 cases (55%).

CONCLUSION

Clinicians should be attentive to the presence of cardiac involvement among patients with suspected ARF. Considering the high incidence of subclinical carditis, echocardiographic evidence of carditis should be used as a diagnostic criterion.

Sensorineural hearing loss in pediatric celiac patients

OBJECTIVE

Celiac disease (CD) is an immune-mediated chronic inflammatory gluten-dependent intestinal disease affecting 0.5-1% of the general population worldwide. CD is underdiagnosed even with sophisticated health care; approximately 10% of people affected by CD are now diagnosed. The recognition of the atypical extra-intestinal manifestations, including neurological disorders increased the diagnosis of CD. At present, no data are available on the presence of sensorineural hearing loss in pediatric CD patients. The aim of this study was to determine the incidence and severity of sensorineural hearing loss (SNHL) in different frequencies in pediatric CD patients.

METHODS

A sample of 32 biopsies and serologically proven newly diagnosed pediatric CD patients (CD group) (64 ears) and 32 sex and age-matched healthy subjects (64 ears) as control group (C group) were included in this study. Anthropometric measurements, physical examinations including ear nose and throat and pure-tone audiometry at frequencies 250-8000 Hz were performed in all subjects in both groups. Slight/mild SNHL was defined as a loss of detection of sound within the 16-40 dB range. The mean age of patient and control group was 11.9 and 11.3, respectively (p>0.05).

RESULTS

In CD group, sensorineural hearing loss was found in 13 (40.6%) patients (group A) as it was bilateral in six and unilateral in seven patients. In control group (group C), slight/mild SNHL was found in one (3.1%) subject. The frequency of hearing loss was significantly higher in CD group than in group C (p<0.001).

CONCLUSION

The present study showed a higher prevalence of sensory neural hearing loss in pediatric celiac patients than in healthy controls, suggesting an association between CD and SNHL. The findings of this study suggest that hearing impairment should be searched in newly diagnosed pediatric CD patients. Further longitudinal investigations on a larger sample size will be necessary to confirm the present data and to search the immunological processes which could be the basis of the association between CD and SNHL.

Echocardiographic findings in children with Marfan syndrome

Background

The typical cardiac manifestations of Marfan syndrome are aortic regurgitation with progressive dilatation of the aortic root, which may cause dissection and rupture of the ascending aorta, mitral valve prolapse and mitral valve regurgitation. In this study, we aimed to show echocardiographic findings in 11 patients with Marfan syndrome.

Methods

Diagnosis of Marfan syndrome was based on the Ghent criteria. All patients had a full echocardiographic evaluation. During the evaluation, we investigated the presence of mitral valve prolapse, mitral valve regurgitation, tricuspid valve prolapse, dilatation of the aortic root, and aortic regurgitation.

Results

Eleven patients were diagnosed as Marfan syndrome (seven male, four female, age 4–14 years). All had mitral valve prolapse (nine with mitral valve regurgitation). Among these 11 patients, seven had accompanying tricuspid valve prolapse, six had dilatation of the aortic root and two had aortic regurgitation.

Conclusion

Eleven patients in our clinic were diagnosed as Marfan syndrome since they had distinct characteristics of marfanoid phenotype. Echocardiographic evaluation of these patients showed marked heart valve involvement. In Marfan syndrome, it is known that the aortic valve is affected following mitral valve involvement. In our experience, aortic root dilatation is less common. However, particular attention should be given to following up aortic root status with non-invasive echocardiography to institute measures to prevent complications.

Type I plasminogen activator inhibitor 4G allele frequency is associated with chronic venous insufficiency

Chronic venous insufficiency (CVI) is a common disease associated with poor quality of life. Genetic polymorphisms causing coagulation abnormalities may account for some of the CVI pathogenesis. Type I plasminogen activator inhibitor (PAI-1) is responsible for fibrinolytic system regulation, and plasma levels of PAI-1 are strongly correlated with PAI-1 4G/5G gene polymorphism. The association between PAI-1 4G/5G gene polymorphism and CVI was investigated. In 34 consecutive patients with clinically overt CVI, the PAI-1 4G/4G polymorphism was detected in three cases (8.8%); the 4G/5G polymorphism was detected in 28 (82.4%). In 34 age- and sex-matched controls, the PAI-1 4G/4G polymorphism was detected in one case (2.9%) and the 4G/5G polymorphism was detected in 14 cases (41.2%). The PAI-1 4G allele was found significantly more frequently in CVI patients than in controls. The 4G allele was associated with a 3.25-fold increase in CVI risk. Thus, a relationship between CVI and the PAI-1 4G allele is apparent.

Relation of subepicardial adipose tissue thickness and clinical and metabolic parameters in obese prepubertal children

BACKGROUND

The measurement of subepicardial adipose tissue thickness (SATT) has been found to be related to insulin resistance (IR) in adults. Until now, the association between SATT and IR has not been evaluated in obese prepubertal children. We aimed to determine the relation of SATT with clinical anthropometric and metabolic parameters and to provide cutoff value of SATT associated with IR in obese prepubertal children.

METHODS

Fifty-two obese (mean age: 9.5 ± 1.6 years, 29 female) and 31 lean prepubertal age- and gender-matched subjects (mean age: 9.2 ± 1.4 years, 12 female) were evaluated by echocardiography. SATT was measured by transthoracic echocardiography.

RESULTS

SATT (6.54 ± 1.38 mm) and homeostatic model assessment-insulin resistance (HOMA-IR) (3.2 ± 2) values of obese prepubertal subjects were significantly higher than those of the lean subjects (3.72 ± 0.57 mm and 1.6 ± 1) in the control group (both p < 0.001). Bivariate correlation analysis showed significant correlation between SATT, age, body mass index (BMI), waist circumference (WC), hip circumference (HC), waist-to-hip ratio (WHR), mid-arm circumference (MAC), triceps skin fold (TSF) thickness, insulin, and HOMA-IR (r = 0.547, r = 0.524, r = 0.543, r = 0.431, r = 0.289, r = 0.402, r = 0.400, r = 0.328, r = 0.289, p < 0.05, respectively). As an optimal cutoff point, an SATT of 4.33 mm determined IR with 93.3% sensitivity and 51% specificity.

CONCLUSIONS

Our study on obese prepubertal children showed that SATT was significantly correlated with age, BMI, WC, HC, MAC, TSF, insulin, and HOMA-IR.

Plesiomonas shigelloides sepsis and meningoencephalitis in a surviving neonate

In this study, we report the case of a 2.5-day-old neonate with septicemia and meningitis due to Plesiomonas shigelloides. Culture of the cerebrospinal fluid showed Gram-negative rods, although the glucose, protein and leukocyte counts were normal. The patient was treated with meropenem and survived without any sequelae, although we were not able to identify the source of the infection. In addition, ten previously reported cases of this infection are reviewed.

Subepicardial adipose tissue thickness and its relation with anthropometric and clinical parameters in pubertal obese children

AIM

To determine the relation of echocardiographic subepicardial adipose tissue (SAT) thickness with anthropometric and clinical parameters in pubertal obese children.

SUBJECTS AND METHODS

A total of 52 obese pubertal subjects (13.1±1.56 yr, 27 male patients) and 39 age- and gender-matched lean pubertal subjects (13.0±1.28 yr, 16 male patients) were included in the study. Serum glucose, lipid profile, and insulin levels were measured during the fasting state. Each subject underwent a transthoracic echocardiography and the SAT thickness was measured during end-diastole from the parasternal long-axis views.

RESULTS

The obese pubertal subjects had significantly higher SAT, triceps skin fold (TSF) thickness (mm), waist (WC) and mid-arm circumference (MAC) values (cm) compared with lean pubertal subjects group (p<0.05). Correlation analysis showed that SAT thickness was significantly related with age, SD score-body mass index (SDS-BMI), BMI, WC, MAC, TSF, and homeostasis model assessment of insulin resistance (HOMA-IR) (p<0.05), whereas there was no significant relation of SAT with hip circumference and waist to hip ratio (p>0.05). As an optimal cut-off point, a SAT thickness of 5.25 mm determined IR with 92% sensitivity and 62.1% specificity.

CONCLUSIONS

Our study showed that SAT thickness in obese pubertal children shows a good correlation with age, SDS-BMI, BMI, WC, MAC, TSF, and HOMA-IR. In addition, our results suggest that SAT thickness might be used as a supportive data for risk stratification of metabolic syndrome in obese children.

Ulnar nerve entrapment in Guyon's canal due to a lipoma

Guyon's canal syndrome is an ulnar nerve entrapment at the wrist or palm that can cause motor, sensory or combined motor and sensory loss due to various factors . In this report, we presented a 66-year-old man admitted to our clinic with a history of intermittent pain in the left palm and numbness in 4th and 5th finger for two years. His neurological examination revealed a sensory impairment in the right fifth finger. Also, physical examination displayed a subcutaneous mobile soft tissue in ulnar side of the wrist. Electromyographic examination confirmed the diagnosis of type-1 Guyon's canal syndrome. Under axillary blockage, a lipoma compressing the ulnar nerve was excised totally and ulnar nerve was decompressed. The symptoms were improved after the surgery and patient was symptom free on 3rd postoperative week.

Echocardiographic measurement of epicardial adipose tissue in obese children

The echocardiographic measurement of epicardial adipose tissue (EAT) has been suggested as an easy method for evaluation of the visceral adipose tissue and its related cardiovascular risks in adults. However, a direct effect of obesity on cardiac function is not well established, and echocardiographic EAT thickness has not been studied in children. The aims of this study were to evaluate cardiac function and echocardiographic EAT thickness and to correlate EAT with the other echocardiographic findings in obese children. The study population included 106 obese and 62 lean children. Echocardiographic indexes of systolic and diastolic function were obtained. We measured EAT thickness on the free wall of the right ventricle from parasternal long-axis views. The septal and posterior wall thicknesses, relative wall thickness, left atrial diameter, and left ventricular mass were increased (p = 0.001) in obese children. However, systolic and diastolic functions of the left ventricle were normal in the patients. The obese children had a significantly thicker EAT (p = 0.001) compared to the lean subjects. EAT thickness correlated significantly with body mass index (r = 0.50, p = 0.001), left atrial diameter (r = 0.37, p = 0.001), and left ventricular mass (r = 0.33, p = 0.001). In conclusion, the present study demonstrates a close relationship between EAT thickness and obesity in children. Assessment of EAT thickness in routine echocardiographic examinations might be used as a feasible and reliable method for the evaluation of obesity and its related cardiovascular risks during childhood.

Various effects of different probiotic strains in allergic disorders: an update from laboratory and clinical data

Epidemiological data show that allergic children have a different intestinal flora from healthy children with higher levels of Clostridia and lower levels of Bifidobacteria. Nonetheless, Bifidobacteria and Lactobacilli are found more commonly in the composition of the intestinal flora of non-allergic children. Probiotics are ingested live microbes that can modify intestinal microbial populations in a way that benefits the host and they are represented mainly by Lactobacilli. Enhanced presence of probiotic bacteria in the intestinal microbiota is found to correlate with protection against atopy. There is also very promising evidence to recommend the addition of probiotics to foods for the prevention and treatment of allergic diseases. Clinical improvement, especially in allergic rhinitis and immunoglobulin (Ig)E-sensitized (atopic) eczema, has been reported in most of the published studies. However, clinical benefit of probiotic therapy depends upon numerous factors, such as type of bacterium, dosing regimen, delivery method and other underlying host factors, e.g. the age and diet of the host. Selection of the most beneficial probiotic strain, the dose and the timing of supplementation still need to be determined. This review helps understanding of the role of probiotics in various allergic diseases, explaining laboratory and clinical data in light of recent literature.

Characterisation of medical-waste sterilisation-plant wastewater and a preliminary study of coagulation-flocculation treatment options

Wastewater from a medical-waste sterilisation plant (MWSP) contains unique pollutants and requires on-site treatment to prevent contamination of the municipal sewage system and receiving water bodies. Therefore, to meet the prescribed discharge standards and comply with the legal regulations, pre-treatment must be applied to MWSP wastewater. In this study, the capabilities of coagulation-flocculation processes were investigated for MWSP wastewater treatment. Processes using ferric chloride, ferrous sulfate and aluminium sulfate as coagulants were characterised. During the coagulation experiments, seven different coagulant dosages and four different pH values were evaluated to determine the optimum coagulant dosage and pH value. The highest removal efficiency of chemical oxygen demand (COD) was obtained using 300 mg/L of ferric chloride at pH 10. A COD removal of about 60% as well as considerable reductions in the amounts of suspended solids, nitrogen and phosphorus were realised.

Eisenmenger syndrome and juvenile rheumatoid arthritis--a case of double diagnosis

An 8.5-year-old girl evaluated for central cyanosis, hypoxia and normocarbia was found to have aorticopulmonary window and pulmonary hypertension. The diagnosis of Eisenmenger syndrome (ES) was made and treatment with bosentan was started. Four months later she was diagnosed to have juvenile rheumatoid arthritis and naproxen treatment was started. The case was remarkable in that she showed clinical improvement with new generation treatment of ES although pulmonary arterial pressure did not decrease significantly and the diagnosis of juvenile rheumatoid arthritis was made during follow-up.

Psychotic disorder and extrapyramidal symptoms associated with vitamin B12 and folate deficiency

Vitamin B12 and folate deficiency causing neuropsychiatric and thrombotic manifestations, such as peripheral neuropathy, subacute combined degeneration of cord, dementia, ataxia, optic atrophy, catatonia, psychosis, mood disturbances, myocardial infarction and portal vein thrombosis are well known. This present report highlights an unusual presentation of vitamin B12 deficiency-psychotic disorder, extrapyramidal symptoms in a 12-year-old boy. His symptoms responded to parenteral vitamin B12 therapy. So with this report we emphasized that serum vitamin B12 and folate levels should be measured, especially in those patients who present with other known neuropsychiatric features of vitamin B12 and folate deficiency.

Craniorachischisis totalis: a case report and review of the literature

OBJECTIVE

To discuss a fetus with craniorachischisis diagnosed antenatally and to review the literature.

METHOD

Case report.

RESULTS

Craniorachischisis was detected on ultrasound scan in a fetus at gestational week 13. Pregnancy was terminated and diagnosis was verified postnatally.

CONCLUSION

Craniorachischisis is a rare and severe form of neural tube defects (NTDs). The majority of currently known cases of mouse craniorachischisis have been found to result from disturbance of a single molecular signaling cascade, called planar cell polarity pathway (PCP). The mutant genes that have been causative in disturbance of PCP in mouse models have been examined in human malformations but none of them have so far been implicated in human craniorachischisis. To date, no other genes except the gene encoding 5,10-methylenetetrahydrofolate reductase have been specifically implicated in predisposition to NTDs. We suggest that other PCP genes should be considered as candidates for a role in the etiology of human NTDs. Further investigations are therefore necessary.

Effect of stage 2 kindling on local cerebral blood flow rates in rats with genetic absence epilepsy

PURPOSE

Genetic absence epilepsy rats from Strasbourg (GAERS) are resistant to the progression of kindling seizures. We studied local cerebral blood flow (LCBF) changes in brain regions involved in seizures in both GAERS and nonepileptic rats (NEC) to map the differences that may be related to the resistance to kindling.

METHODS

Electrodes were implanted in the amygdala of adult NEC and GAERS male rats, which were stimulated to reach stage 2. Quantitative autoradiographic measurements of LCBF were performed by the [(14)C]-iodoantipyrine ([(14)C]IAP) autoradiographic technique allowing the precise mapping of regional perfusion changes. LCBF rates were measured bilaterally in 43 brain regions. The tracer infusion lasted for 60 s and started at 15 s before seizure induction.

RESULTS

Rates of LCBF increased in stimulated GAERS and NEC groups compared to nonstimulated controls. The LCBF increase in stimulated GAERS was larger and more widespread than that observed in stimulated NEC. The LCBF increase in the somatosensory cortex, ventrobasal and anterior thalamic nuclei, hypothalamus, subthalamic nucleus, piriform, entorhinal and perirhinal cortex, amygdala, CA2 region of hippocampus, and substantia nigra was statistically significantly larger in stimulated GAERS compared to stimulated NEC rats.

CONCLUSION

The results show that more brain regions are activated by kindling stimulation in GAERS. This widespread activation in GAERS involves the somatosensory cortex and thalamus, which are both known to be involved in the expression of absence seizures as well as numerous limbic regions thought not to play a role in the expression of absence seizures, suggesting an interaction between corticothalamocortical and limbic circuitries.

Intra-arterial thrombolysis of occluded middle cerebral artery by use of collateral pathways in patients with tandem cervical carotid artery/middle cerebral artery occlusion

BACKGROUND AND PURPOSE

Cervical internal carotid artery (ICA) occlusion with middle cerebral artery (MCA) embolic occlusion is associated with a low rate of recanalization and poor outcome after intravenous thrombolysis. Prompt revascularization is required to prevent disabling stroke. We report our experience on acute ischemic stroke patients with tandem ICA or MCA occlusions treated with microcathether navigation and intra-arterial thrombolysis by use of collateral pathways including the posterior or anterior communicating arteries, or both pathways.

MATERIALS AND METHODS

We retrospectively identified 8 patients with proximal ICA occlusion associated with MCA embolic occlusions treated with intra-arterial thrombolysis (IA rtPA). Access to the occluded MCA was obtained via catheter navigation through intact collateral pathways, including posterior communicating (PcomA) or anterior communicating (AcomA) arteries, without passing a microcathether through the acutely occluded ICA. We assessed clinical outcomes using modified Rankin scale (mRS) and National Institutes of Health Stroke Scale (NIHSS).

RESULTS

Eight patients with a mean age of 57 +/- 4 years and median NIHSS of 14 were identified. Mean time from stroke onset to intra-arterial thrombolysis was 292 +/- 44 minutes. The MCA was revascularized completely in 5 of the 8 patients via collateral intra-arterial rtPA administration. All of the patients had a favorable outcome defined as a mRS of < or =2 or more at 1 and 3 months' follow-up after thrombolytic therapy. One patient had an asymptomatic petechial hemorrhage.

CONCLUSION

In this small number of patients with tandem occlusions of the ICA and MCA, intra-arterial thrombolysis and recanalization of the MCA by use of collateral pathways to bypass the occluded ICA is a safe and efficacious therapeutic option.

A case with diffuse uterine leiomyomatosis and review of the literature

Leiomyomas and diffuse uterine leiomyomatosis are smooth muscle tumors of the uterus. Diffuse uterine leiomyomatosis is a benign and extremely rare condition in which the uterus is symmetrically enlarged as a result of the almost complete replacement of the myometrium by innumerable poorly defined, confluent nodules. The etiology of these neoplasms is not completely understood. Initial symptoms of the diffuse uterine leiomyomatosis usually are abdominal pain and abnormal uterine bleeding. Similar to uterine leiomyomas, patients with leiomyomatosis present with menorrhagia, dysmenorrhea, abdominal pain, infertility, and pelvic pressure. Hormonal treatment usually fails to control the symptoms, anemia, or tumor growth after treatment is stopped. As a result, despite patients being in the third or fourth decades of life, hysterectomy has been the only permanent treatment option offered to patients for treatment of the symptoms related to uterine fibroids in diffuse leiomyomatosis. A case of a patient with a huge uterine mass (2,650 g in weight) who underwent hysterectomy due to diffuse uterine leiomyomatosis is presented together with a review of the literature.

Endothelial nitric oxide synthase gene [G894T] polymorphism as a possible risk factor in aneurysmal subarachnoid haemorrhage

BACKGROUND

The exact aetiology, growth and rupture of intracranial aneurysms is unclear. In this study we investigated a possible association between intracranial aneurysm rupture and polymorphism of the endothelial nitric oxide synthase gene G894T.

METHODS

Endothelial nitric oxide synthase gene polymorphism of 53 patients with ruptured intracranial aneurysms and 60 control subjects were analysed by the polymerase chain reaction-restriction fragment length polymorphism technique. The genotype distribution and allele frequencies of endothelial nitric oxide synthase gene polymorphism in patients with ruptured intracranial aneurysm and healthy subjects were compared.

FINDINGS

The homozygous (TT) genotype frequency was significantly higher in patients with ruptured intracranial aneurysms. It was also found that the presence of eNOS 894TT genotype was significantly associated with the risk of intracranial aneurysm rupture (p < 0.05).

CONCLUSION

Polymorphism in exon 7 of the endothelial nitric oxide synthase gene G894T seems to be a possible risk factor for intracranial aneurysm rupture.

CA 19-9 can be a useful tumor marker in ovarian dermoid cysts

PURPOSE

To evaluate the importance of CA-19-9 as an aiding tool in the diagnosis of mature cystic teratomas.

METHODS

We found 43 cases of dermoid cysts that were operated on at our clinic, and whose tumor marker CA 19-9 was studied before the operation.

RESULTS

Thirty-seven of 43 patients (86%) had elevated CA 19-9 levels. Using Pearson's correlation, the average diameter and weight of the tumor had a strong possitive correlation with the level of CA 19-9 (p < 0.01). Thirty-one out of the 43 (72%) cases had a dermoid cyst in the right ovary, nine (20.9%) in the left ovary, and three (7%) had bilateral dermoid cysts. Right predominancy was very high among the patients (p < 0.05).

CONCLUSION

We suggest that besides ultrasonography and computed tomography, serum CA 19-9 level could be a useful tumor marker in the diagnosis of dermoid cysts.
