BACKGROUND: Previous studies have reported a circadian variation of ventricular tachyarrhythmias. However, there is no detailed information of the daily distribution of ventricular tachycardia (VT) and ventricular fibrillation (VF) episodes. The purpose of this study was to evaluate the daily distribution of episodes of ventricular tachyarrhythmia in patients with implantable cardioverter defibrillators. MATERIAL/METHODS: We used data stored by last-generation implantable cardioverter-defibrillators (ICD) to retrospectively evaluate the circadian distribution of VT and VF in 70 patients with ICD. The distribution of tachyarrhythmias was categorized into four time zones: zone 1 (06:00-11:59), zone 2 (12:00-17:59), zone 3 (18:00-23:59), and zone 4 (00:00-05:59). RESULTS: During a follow-up of a mean of 3.1+/-1.3 years, a total of 791 ventricular arrhythmias were recorded from which 631 events were VT and 160 VF. A circadian variation of episodes of ventricular tachyarrhythmia was evident. The incidence of ventricular arrhythmia sharply increased in zone 1 (8.82+/-2.13, p<0.0001). Episodes of VT had peaks in zones 1 and 2 (7.44+/-2.03 and 2.70+/-0.65, p<0.001) and episodes of VF had peaks in zones 1 and 4 (1.38+/-0.39 and 1.30+/-0.51, p<0.011). No difference was observed between patients who used betablocker and those who did not. CONCLUSIONS: Malignant ventricular tachyarrhythmias have a circadian distribution. VT peaks occur in the morning and noon hours and VF peaks occurs at the night and morning hours. Betablocker and/or amiodarone usage do not alter this distribution. 相似文献

Intraoperative localisation and management of coronary artery fistula using transesophageal echocardiography. 总被引:2,自引:0,他引:2

Coronary artery fistula is a rare congenital malformation that can be complicated by intracardiac shunts, endocarditis, myocardial infarction, coronary aneurysm and sudden death. Clinical symptomatology depends upon the underlying anatomy and the size of the fistulous connection between the left or right side of the heart. We report the successful management of a giant right coronary artery with fistulization into the right atrium. Intraoperative transesophageal echocardiography with colour flow Doppler was used for precise location of the fistulous communication, selective demonstration of vessels feeding the fistula and documentation of abolition of fistulous flow all without the need for cardiopulmonary bypass. Furthermore the effect of shunt occlusion on regional wall motion was documented which facilitated the successful ligation of the fistula. 相似文献

OBJECTIVES: Chest trauma in childhood is uncommon in clinical practice. The management and treatment principles of children with thoracic trauma were discussed with the data reported in the literature. METHODS: Of the chest injury diagnosed in 1653 patients, 225 were children in the last 17-year period. There were 199 boys (88.44%) and 26 girls (11.55%). The most common causes were blunt injuries in 135 cases (60%), stab wounds in 67 cases (29.77%) and gunshot wounds in 22 cases (9.77%). RESULTS: Out of 225, 217 patients were treated conservatively and eight patients were treated surgically. There was no mortality and morbidity. CONCLUSIONS: The prevalence of chest trauma in children due to blunt injuries is high in Turkey. Extremity injury is thought to be the most commonly associated extra-thoracic injury. However, thoracic trauma in children can be managed conservatively in most of the cases. 相似文献

OBJECTIVES: To compare the clinical features and the surgical approaches between single pulmonary (SPH) and hepatopulmonary hydatidosis (HPH). METHODS: The hospital and follow-up records of 141 patients who had undergone surgery for pulmonary hydatidosis in our clinic between January 1991 and January 2001 were reviewed. Forty-nine patients (34.8%) had concomitant liver cysts in addition to the pulmonary cysts and they were regarded as HPH (Group I). The remaining 92 (65.2%) patients had SPH (Group II). Both groups were compared according to their clinical, radiological and surgical features. RESULTS: Seventeen (34.7%) male and 32 (65.3%) female patients had HPH. The mean age of the patients with HPH was significantly higher than the age of those with SPH (P<0.05) and the frequency of hepatopulmonary localization, which is contrary to single pulmonary cyst, was significantly higher in females (P<0.05). The majority (67.3%) of the cysts located in the liver were solitary. Multiple pulmonary cysts were in higher ratio in Group II, compared to Group I (45.7 vs. 22.8%) and bilateral pulmonary cyst ratio was higher in Group II, as well (26.5 vs. 13%) (P<0.05). In 14 patients (28.6%), the concomitant cysts localized in the dome of liver were extirpated via right thoracophrenotomy, and in one of them sternophrenotomy was performed. There was no statistically significant difference associated with the postoperative complications and hospital stay between groups. No recurrence and mortality were recorded in Group II. CONCLUSIONS: Multi-organ localizations (especially liver) should be examined in all patients with pulmonary hydatid cysts. HPH is more frequent in female patients over 40 years of age. The pulmonary cysts in HPH show a tendency to be bilateral and multiple. HPH should be regarded as a different entity since it can cause either economic or labour loss due to the multi-operations and prolonged postoperative care. The operative strategy and approach should be different in hepatopulmonary cysts especially if they locate in the right or bilateral lung. One-session operation with the improvements of its techniques and methods should be considered in selected cases. 相似文献

When inferior vena caval obstruction complicates the Budd-Chiari syndrome, conventional portosystemic shunts are not possible. The mesoatrial shunt has been devised to enable portal and sinusoidal decompression in these patients. Findings in 12 patients with Budd-Chiari syndrome and inferior vena caval obstruction in whom a mesoatrial shunt was performed are reported. Preoperative inferior vena cavography with pressure measurements is essential to determine the appropriate shunt procedure. Postoperatively, shunt patency is assessed with superior mesenteric arterial portography. Where possible, transvenous catheterization of the shunt is performed to confirm patency and assess hemodynamic function. 相似文献

Wastewater treatment activities in the chemical industry have generated abundant gypsum waste, classified as scheduled waste (SW205) under the Environmental Quality Regulations 2005. The waste needs to be disposed into a secure landfill due to the high heavy metals content which is becoming a threat to the environment. Hence, an alternative disposal method was evaluated by recycling the waste into fired clay brick. The brick samples were incorporated with different percentages of gypsum waste (0% as control, 10, 20, 30, 40 and 50%) and were fired at 1050 °C using 1 °C per minute heating rate. Shrinkage, dry density, initial rate of suction (IRS) and compressive strength tests were conducted to determine the physical and mechanical properties of the brick, while the synthetic precipitation leaching procedure (SPLP) was performed to scrutinize the leachability of heavy metals from the crushed brick samples. The results showed that the properties would decrease through the incorporation of gypsum waste and indicated the best result at 10% of waste utilization with 47.5% of shrinkage, 1.37% of dry density, 22.87% of IRS and 28.3% of compressive strength. In addition, the leachability test highlighted that the concentrations of Fe and Al was significantly reduced up to 100% from 4884 to 3.13 ppm (Fe) and from 16,134 to 0.81 ppm (Al), respectively. The heavy metals content in the bricks were oxidized during the firing process, which signified the successful remediation of heavy metals in the samples. Based on the permissible incorporation of gypsum waste into fired clay brick, this study promised a more green disposing method for gypsum waste, and insight as a potential towards achieving a sustainable end product. 相似文献

Hidradenitis suppurativa is a chronic, debilitating inflammatory disease of apocrine glands characterized with abscesses and nodular lesions. The
treatment of Hidradenitis suppurativa consists of topical antibacterial or antiseptic solutions, systemic antibiotics, steroids, hormonal therapy, anti-tumor necrosis
factor, and various surgical procedures. In this report, we present a series of 14 cases with severe Hidradenitis suppurativa. Surgical options are reviewed to show the best outcomes in the long term. A total of 14 patients (9 female, 5 male) were
treated for advanced cases of Hidradenitis suppurativa. They underwent excision of the affected regions followed by reconstruction. The reconstruction methods consisted of split-thickness
skin grafting and various cutaneous and myocutaneous flaps. There was no flap necrosis or dehiscence. One patient developed
contracture in the axilla, for which he underwent release surgery. There were recurrences in 4 cases. There was no limitation
of the arm movements in cases with flap reconstruction. In the long-term, they were satisfied with the results. In conclusion,
incision and drainage should be avoided because it is of limited value. Surgical removal of the involved tissue should be
the first treatment of choice. Depending on the defect following excision, local flaps should be preferred over the grafts
for recurrence prevention. 相似文献
