Perigraft to right atrial shunt by using autologous pericardium for control of bleeding in acute type A dissections

BACKGROUND: We report our experience with creating a perigraft to right atrial fistula by using autologous pericardium to control the inaccessible bleeding after aortic root repair in patients with acute type A aortic dissection. METHODS: Between 1994 and 2001, perigraft to right atrial fistula was used in 7 of 109 patients (mean age; 55 years) who underwent emergency operation for acute type A dissections. A chamber around the aortic graft was created by suturing a patch of pericardium to the right ventricular wall inferiorly, to the pulmonary artery medially, to the Teflon felt at the distal aortic anastomosis or innominate vein superiorly, and to the superior vena cava and right atrium laterally. A large stab wound was created on the medial aspect of the right atrium. The perigraft space was then closed expeditiously. RESULTS: None of these patients required reexploration for bleeding and they were discharged from the hospital without complications. The average blood and fresh frozen plasma requirement was 3.4 +/- 0.9 and 2.7 +/- 0.7, respectively. All underwent echocardiographic examination before discharge and no perigraft to right atrial shunt was detected. CONCLUSIONS: If intractable bleeding is encountered after the administration of protamine and thrombotic agents and a discrete bleeding site can not be found, then a perigraft to right atrial fistula using autologous pericardium can be created as a last resort. It provides primary and definite sternal closure and avoids the detrimental effects of a second pump run and continued bleeding.     

Translation, cultural adaptation, initial reliability, and validation of Turkish 15D's version: a generic health-related quality of life (HRQoL) instrument

This article describes the adaptation of the Finnish 15D standardized measure of health-related quality of life (HRQoL) instrument for use in Turkey and assesses its psychometric properties. The HRQoL is measured in a sample of 75 patients with Type 2 diabetes using both 15D and Nottingham Health Profile (NHP) instruments. The internal consistency within the domains of 15D was high, with Cronbach's alpha values 0.89 for 15D scale and 0.89 for NHP. Significant correlations were observed between the scores of similar domains of 15D and the NHP in general health perception supporting the construct validity of the new 15D Turkish version. Overall, the results indicated that the adaptation of the 15D for use in Turkey was successful. The Turkish version was found to be a reliable and valid instrument. It is suitable and applicable to both clinical and population-based studies for the measurement of HRQoL in Turkey.     

Painful traumatic neuroma after a finger stick

In this case report we present a patient with a painful traumatic neuroma after a finger stick by lancet. The patient benefited from surgical excision of the lesion, and her symptoms were completely abolished with additional sympathetic nerve blocks.     

Spinal pelvic reconstruction after total sacrectomy for en bloc resection of a giant sacral chordoma. Technical note

Although radical resection prolongs the disease-free survival period, surgical management of primary sacral tumors is challenging because of their location and often large size. Moreover, in cases of lesions for which a radical resection necessitates total sacrectomy, reconstruction is required. The authors have previously described a modified Galveston technique in which a liaison between the spine and pelvis is achieved using lumbar pedicle screws and Galveston rods embedded into the ilia; additionally, a transiliac bar reestablishes the pelvic ring. Although this reconstruction technique achieves stabilization, several biomechanical limitations exist. In the present report the authors present the case of a patient who underwent spinal pelvic reconstruction after a total sacrectomy was performed to remove a giant sacral chordoma. They describe a novel spinal pelvic reconstruction technique that addresses some of the biomechanical limitations.     

Foreign body asphyxiation in children

We aimed to investigate the frequency and epidemiological features of deaths due to foreign body asphyxiation (FBA) in childhood, over 1990-2003. Of the victims, 14 (63.6%) were male and 8 (36.4%) females. The mean age of the victims was 2.2 +/- 0.6 years. There were 20 (90.9%) children between 1 and 3 years, and two other cases at 2/12 and 5 years of ages. All aspirations had occurred at home. Eight (36.4%) of the victims were dead on arrival, 11 (50%) on intervention, and 3 (13.6%) after complications. Food material was the most commonly aspirated foreign body in 81.8% of the cases, nuts being the most common (50%). Food asphyxiation remains a common problem particularly in children between 1 and 3 years of age in our region. These fatal accidents can be prevented by parental education and early recognition and management of the situation.     

Nitric oxide involvement in seizures elicited by pentylentetrazol and sex dependence

It has been known that susceptibility to some types of epilepsy is affected by sex. In addition, the role of NO in epileptogenesis is still unclear; NO has been suggested to be either an anticonvulsive or a proconvulsive agent. In an attempt to elucidate both the role of NO and sex differences in sensitivity to seizures, male and female Wistar rats were treated intraperitoneally (i.p.) by pentylentetrazol (PTZ)(80 mg/kg) and by a nitric oxide synthase(NOS) inhibitor N-omega-nitro-L-arginine-mthylester(L-NAME)(50mg/kg) and a NO precursor sodium-nitroprusside(SNP)(2.5mg/kg)- applied 15 min. before PTZ injection. Latency, frequency, severity, and duration of generalized clonic and clonic-tonic convulsions were recorded. Furthermore, alterations in severity, latency, frequency, and duration of convulsions were observed to correlate with NO. Both sexes, injected with PTZ, showed repetitive seizure patterns. Seizures were found to be more severe in females. L-NAME and SNP pretreatment produced paradoxical effects on PTZ-induced seizures in both sexes. L-NAME completely prevented PTZ-induced seizures in male rats, whereas increased severity, frequency, duration, and significantly shortened the latency in female rats. Unexpectedly, SNP increased convulsion severity, frequency, duration, and shortened latencies in male, whereas it decreased convulsion severity, frequency, and duration and prolonged latency in females. These results indicate that endogenous NO is involved in the regulation of convulsive action suggesting a role depending on sex.     

Scintigraphic findings in osteoarticular brucellosis

AIMS: To describe the distribution of bone and joint involvement in 197 patients with brucellosis, and to detail a spectrum of findings on bone scintigraphy in 38 patients with brucellar spondylitis. METHODS: One hundred and ninety-seven patients (141 females, 56 males; age range, 5-77 years) with osteoarticular brucellosis were studied. Patients were classified into acute (62%) and chronic (38%) stages of the disease, and into age groups of less than 16 (1%), 16-30 (17%), 31-45 (29%), 46-60 (37%) and over 60 (16%) years. All patients were evaluated with Tc-methylene diphosphonate bone scanning. Quantification of sacroiliac joint uptake was performed to improve the sensitivity for the detection of sacroiliitis. Plain radiography and computed tomography (CT) or magnetic resonance imaging (MRI) were performed, when required, to evaluate the areas of the skeleton that showed abnormal uptake on the bone scan. MRI and single photon emission computed tomography (SPECT) were performed in all patients who had spinal lesions. RESULTS: The sites most commonly affected were the sacroiliac joints (53%) and spine (19%), followed by the shoulders (16%). Osteoarticular involvement was more common in females (72%) than in males (28%), and the acute stage (62%) was observed more than the chronic stage (38%). Bone and joint involvement occurred at any age, but the most common age group was 46-60 years. Eight scintigraphic patterns were identified in spinal involvement. CONCLUSION: Brucellosis may affect the musculoskeletal system at any site. Bone scan is a useful method to detect osteoarticular involvement in cases of relapse and progression. Spine involvement has the widest range of scintigraphic findings. A knowledge of the location and distribution of osteoarticular involvement as revealed on the bone scan of patients with brucellosis may be valuable in patient treatment and management.
