Cardiac involvement of hydatid cysts is rare. Hydatidosis of the valvular apparatus can be treated successfully by the careful application of valvular surgical procedures.To the best of our knowledge, cardiac hydatidosis confined to the anterolateral papillary muscle has not been reported. Herein, we present a case involving a hydatid cyst that was located in a cardiac papillary muscle and that caused mitral regurgitation in a 37-year-old woman. The cyst was removed by papillary muscle incision, and the mitral valve was repaired. The patient experienced an uneventful recovery.Key words: Cardiac surgical procedures, echinococcosis/diagnosis/pathology/physiopathology/surgery, echocardiography, heart diseases/parasitology/physiopathology, mitral valve/surgery, treatment outcomeHydatid disease remains a substantial health problem in some areas of the world. Cardiac involvement of hydatid cysts is rare. Here, we present what we believe to be the 1st report of a cardiac hydatid cyst that was completely confined to the anterolateral papillary muscle, and we discuss our surgical treatment of the patient. 相似文献

Various diagnostic imaging modalities have been used for quantitative left ventricular (LV) parameters. Because of the suboptimal value of the most widely used technology, two-dimensional (2D) echocardiography, 3D ultrasonographic imaging has improved accuracy for LV volume and function. Single photon emission computed tomography (SPECT) is another diagnostic method where LV volumetric and functional parameters can be accurately provided by gated myocardial perfusion tomographic slices. First pass radionuclide venticulography is another imaging modality which has some practical limitations. Despite lower ejection fraction (EF) values compared with invasive approach, noninvasive techniques are accurate in determination of normal and depressed EF. Noninvasive techniques with 3D approach including gated SPECT are beneficial for not only global but also regional LV evaluation. It has been mentioned that the slight difference between echocardiography and SPECT could be caused by the diverse population studied. The results of diagnostic stress tests support that SPECT is feasible to use in evaluation of LV volume and functional analysis. Magnetic resonance imaging is an expensive modality to use routinely, but it preserves its importance in selected patients for providing precise LV geometric data. 相似文献

Holoprosencephaly (HPE) and polycystic kidney disease (PKD) are genetically heterogeneous anomalies which can make up part of various syndromes or chromosomal anomalies. Due to the rapid lethality prognosis, early and precise prenatal diagnosis would be of great value. This case report describes extensive PKD involvement, already present in utero, in a patient with HPE and subdural effusion visible by MR imaging. The detailed anatomic information obtained by the MR imaging can guide the surgical planning and can aid antenatal counseling. 相似文献

Methanol is a clear, colorless, and highly toxic liquid with a similar smell and taste to ethanol, and is found in many commercial products such as solvents and cleaning fluids. Severe methanol intoxication occurs after suicidal or accidental oral ingestion of solvents. A few patients with methanol intoxication via the transdermal route have been reported. We present a 47-year-old woman with acute transdermal methanol intoxication admitted to the emergency department with weakness, blurred vision, bilateral areactive mydriasis, and deterioration of consciousness. 相似文献

To investigate whether heavy habitual smoking affects microstructures and functions of the macula, 45 age- (20–39 years old) and sex-matched adult smokers (≥1 box/day for ≥5 years) and 45 nonsmokers (controls) were enrolled in this case–control study. Central macular thickness (CMT), macular autofluorescent pigment density (MAPD), macular electroretinogram (ERG), and photostress recovery time (PRT) measurements were performed. The mean age of smokers and nonsmokers was 32.9 ± 3.9 and 33.1 ± 4.1 years, respectively (p = 0.43), and smoking duration was 11 ± 5.6 years. CMT in smokers (220 ± 28 μm) and nonsmokers (217.2 ± 31 μm; p = 0.57) was similar. Smokers had lower MAPD values (124.6) than nonsmokers (138.2) (p = 0.010). Multifocal ERG parameters in the central (6°) hexagon were similar in both groups (p > 0.05 for latency and amplitudes of P1 and N1). PRT in smokers and nonsmokers was similar (7.2 ± 1.2 and 7.4 ± 1.9 min, respectively; p = 0.33); however, foveal threshold value (FTV) at the first minute after photostress was statistically higher in smokers (36.1 ± 1.04 dB) than nonsmokers (34.8 ± 1.05 dB) (p = 0.011). We conclude that decreased MAPD and altered response to photostress may be indicative of early nicotine toxicity in microstructurally sound macula of adult chronic smokers. 相似文献

Abstract: Nonalcoholic steatohepatitis (NASH) may progress to advanced fibrosis and cirrhosis. Mainly, oxidative stress and excessive hepatocyte apoptosis are implicated in the pathogenesis of progressive NASH. Melatonin is not only a powerful antioxidant but also an anti-inflammatory and anti-apoptotic agent. We aimed to evaluate the effects of melatonin on methionine- and choline-deficient diet (MCDD)-induced NASH in rats. Thirty-two male Wistar rats were divided into four groups. Two groups were fed with MCDD while the other two groups were fed a control diet, pair-fed. One of the MCDD groups and one of the control diet groups were administered melatonin 50 mg/kg/day intraperitoneally, and the controls were given a vehicle. After 1 month the liver tissue oxidative stress markers, proinflammatory cytokines and hepatocyte apoptosis were studied by commercially available kits. For grading and staging histological lesions, Brunt et al.'s system was used. Melatonin decreased oxidative stress, proinflammatory cytokines and hepatocyte apoptosis. The drug ameliorated the grade of NASH. The present study suggests that melatonin functions as a potent antioxidant, anti-inflammatory and antiapoptotic agent in NASH and may be a therapeutic option. 相似文献

When thermal injuries of the hand are managed inappropriately, complex hand contractures are inevitable. Patients with hand
contractures may have many difficulties in their daily life because of this deformity. These patients are challenging to reconstructive
surgeons. In this study we evaluated reverse-flow dorsal metacarpal artery flaps for the defects occurred after metacarpophalangeal
joint contracture release of different fingers. Nineteen patients with defects on the volar surface of metacarpophalangeal
joint were reconstructed by the reverse-flow dorsal metacarpal artery flaps. All operations were successful and flap losses
were not seen. The DMCA flaps provide one stage coverage and permit primary closure of the recipient site. The aesthetic and
functional results are satisfactory without sacrificing main arteries. The only drawback is the residual scar on the dorsum
of the hand, which can be treated by conservative means and may improve over time. 相似文献
