Double-chambered right ventricle (DCRV) is an uncommon congenital heart disease. Anomalous muscle bundles in the right ventricle divide the right ventricle into two portions and cause intracavitary obstruction of the right ventricle. We report a patient with DCRV mimicking asymmetric septal hypertrophy. We did clinical, echocardiographic and angiographic evaluation. Surgical intervention was successfully managed. 相似文献

We aimed to determine the value of maternal erythrocyte malondialdehyde levels in the prediction of preeclampsia. 110 healthy women were included in this prospective study. Maternal erythrocyte malondialdehyde levels were measured at each trimester of pregnancy (10-14, 20-25 and 30-35 gestational weeks). On follow-up, patients were assigned to two groups as normotensive women and preeclamptic patients. Preeclampsia had developed in eight (8.9%) of the 90 pregnant women who completed the study. Preeclamptic patients were diagnosed between 36 and 39 gestational weeks (36.8 +/- 1.0 weeks). Malondialdehyde levels of preeclamptic patients increased significantly in the third trimester (p < 0.05), while there was no difference between values of malondialdehyde in the first and second trimester. Malondialdehyde levels were significantly higher in the patients who developed preeclampsia than in those who did not in the third trimester (p < 0.05). With the use of the receiver operating characteristics (ROC) 35.98 nmol malondialdehyde/gm hemoglobin was found to be a cut-off value predictive for the development of preeclampsia in the third trimester. However, cut-off values in the first and second trimesters could not be found. The sensitivity, specificity, positive and negative predictive values were 89, 75, 29 and 98%, respectively. Preeclampsia risk was found to increase nearly 24 times in values above 35.98 nmol malondialdehyde/ gm hemoglobin. Our results showed that maternal erythrocyte malondialdehyde could predict patients within a few weeks prior to onset of clinical symptoms of preeclampsia in the third trimester. There is no evidence of enhanced early lipid peroxidation in pregnancies with late onset preeclampsia. 相似文献

OBJECTIVES: Extracorporeal shockwave lithotripsy (ESWL) has been applied in sialolithiasis as a new treatment modality. The aim of this experimental study is to investigate the local effects of electrohydraulic ESWL applied to the right submandibular gland of the rats. METHODS: This prospective study was conveyed in four groups; groups I, II, III and IV; each group consisting of 20, 20, 18 and 9 rats, respectively, with a randomized distribution. Groups I, II, III and IV received 250, 500, 1000 and 2000 shock waves at 14-16 kV (average 15.1 kV), respectively, to the right submandibular glands on the 0th day. In groups I, II, III, right submandibular glands of the rats were removed on the 0th, 1st, 7th and 15th days; in group IV, this procedure could be managed only on the 0th and 7th days. Light and electron microscopic evaluation were assessed. Using the light microscopic changes, severity of damage score of the glands (SDS) was found. Statistical analysis was done using SDSs. RESULTS: Light and electron microscopic observations have shown that the damage produced by the shock waves were confined to focal areas in the acinar cells (AC), granulated convoluted tubule (GCT) cells and blood vessels at all doses applied. Vacuolization in the cytoplasms of the AC and GCT cells, disintegration of membranes, alteration in the cytoplasmic organization, swelling of the mitochondria and loss of the features were observed on electron microscopy. Increase in the secretion rate; stasis and dilatation in the blood vessels; blebbing and loss of features in the cytoplasm of the endothelial cells were observed. According to the result of the statistical analysis using SDSs; at 250 shock wave dose, a statistically significant difference between the SDSs of the days (0th, 1st, 7th and 15th) was found (P<0.05). The SDS on the 0th day was found to have the lowest value among the other days. And also a statistically significant difference was found on the 0th day between the SDSs at doses of 250, 500, 1000 and 2000 shock waves (P<0.05). The SDS at 250 and 500 shock waves was found to have the lower value than the SDS at the 2000 shock wave. It was observed that produced damage was less prominent by small doses (250, 500 doses) initially (0th day). Electrohydraulic ESWL caused a "patchy type" generalized pathology on submandibular glands of the rats and damaged focal areas were widespread all through the gland from the 1st day on. CONCLUSION: Formation of the damage was concluded to be related to the direct effect of the shock waves rather than the dose used. Electrohydraulic lithotripters are not suitable for sialolithiasis because of the focus problems, local tissue damage and the risk of the damage to the adjacent structures. 相似文献

OBJECTIVE: Tonsils and adenoids are lymphoid tissues that are located in the pharynx and play an important role against invading antigens of the upper respiratory tract. The present study analyses serum immunoglobulin levels and peripheral blood (PB) lymphocyte subsets in children, 24-48 h prior to and 4-6 weeks after adenotonsillectomy, in order to determine early effects of adenotonsillectomy on the immune system. METHODS: The study population consists of 15 children (aged 4-10 years) who underwent adenotonsillectomy because of adenoidal hypertrophy and chronic tonsillitis and 15 age-matched healthy children without a history of adenotonsillectomy. Serum IgG, IgA and IgM levels were measured by nephelometry. PB lymphocyte subsets were analysed by using monoclonal antibodies and flow cytometry. RESULTS: Children with chronic tonsillitis have increased levels of CD19+ B lymphocytes compared to healthy controls in the pre-operative period. The percentage of B lymphocytes bearing CD23 was found to be significantly higher in patients, most likely representing in vivo B lymphocyte activation due to chronic antigenic stimulation. After the adenotonsillectomy, despite ongoing B lymphocyte activation, CD8+ T lymphocyte levels increased and B cell levels returned to normal. A slight decrease in serum IgG, IgA and IgM levels was detected in the post-operative period compared to prior levels. CONCLUSION: Adenotonsillectomy performed in children leads to alterations that may reflect a compensatory response of the developing immune system after the removal of the lymphoid tissue in the setting of chronic antigenic stimulation. However, these changes do not cause significant immune deficiency. 相似文献

Glandular hamartoma of the larynx is an extremely rare lesion, and the number of well-documented and acceptable cases is limited. Presenting symptoms may include changes in voice, eating and activity levels, and respiratory complaints. We report on a 14-month-old infant with this rare clinical entity. Direct laryngoscopy revealed a well-mucosalized, encapsulated, firm, 0.5 cm wide and 2.5 cm long lesion that originated from the right aryepiglottic fold and reached into the nasopharynx. The mass was completely excised endoscopically. Histopathological examination revealed a hamartoma, which was composed of glandular elements, mixed with mesodermal tissues. After endoscopic removal of the hamartoma, the child was relieved of the obstruction. 相似文献

PURPOSE: To report two patients, 3 and 40 years of age, respectively, each of whom had an isolated intramuscular hemangioma of an extraocular muscle. DESIGN: Two retrospective, interventional case reports. INTERVENTION: Incisional biopsy and short-term oral corticosteroids. MAIN OUTCOME MEASURES: Clinical observation and pathologic examination of specimens and tumor status, visual acuity, and ocular motility at final follow-up. RESULTS: Orbital magnetic resonance imaging revealed that, compared with other extraocular muscles, the tumor was isointense on T1-weighted scans and hyperintense on T2-weighted images. Marked homogeneous enhancement was observed after contrast agent administration. Biopsy results showed a hemangioma of the lateral rectus muscle with predominantly capillary-like small vessels in the child and a mixed small and large vessel type hemangioma of the medial rectus muscle in the adult. CONCLUSIONS: Intramuscular hemangiomas may cause painless, isolated extraocular muscle enlargement in children and in adults without disturbing the ocular motility. The tumors do not seem to be sensitive to systemic corticosteroid therapy. 相似文献

Deltamethrin, a synthetic pyrethroid pesticide contaminating aquatic ecosystems as a potential toxic pollutant, was investigated in the present study for acute toxicity. Guppy fish (Poecilia reticulata) were selected for the bioassay experiments. The 48-h LC50 was determined for the guppies. The experiments were repeated three times and a total of 210 guppies were used. The static test method of acute toxicity test was used. In addition, behavioral changes at each deltamethrin concentration were determined for the individuals. Data obtained from the deltamethrin acute toxicity tests were evaluated using the Probit Analysis Statistical Method. The 48-h LC50 value for guppy was estimated as 5.13 microg/L. 相似文献

Visual evoked potentials in children with occipital epilepsies 总被引:3,自引:0,他引:3
The objectives of this study are to see if any visual evoked potential (VEP) differences are present in two forms of occipital epilepsy, childhood epilepsy with occipital paroxysms (CEOP) and symptomatic occipital epilepsy (SOE) with respect to etiology, as CEOP is a benign age- and localization-related idiopathic epilepsy while SOE is a symptomatic form. Nineteen patients with CEOP and 13 patients with SOE were included in the study and P100 potential latency and amplitude values obtained from these patients were compared with the values recorded from normal controls. The amplitude values recorded from the patients with CEOP were significantly high (P=0.033). P100 potential latency values recorded in patients with SOE were significantly long (P=0.028). High amplitude VEP responses were mostly attributed to hyperexcitability of the occipital cortical structures whereas prolonged latency P100 responses were attributed to occipital structural changes. 相似文献
