Recurrent pericardial effusion due to gunshot wound of the heart in a hemodynamically stable child--a case report.

A 12-year-old girl presented with recurrent pericardial effusion due to firearm pellet injury to the left ventricle. The pellet was localized by two-dimensional echocardiography within the left ventricular apical wall. Since the patient was asymptomatic, left ventriculotomy was avoided to extract the pellet and only pericardial tube drainage was carried out. A slightly elevated blood lead level of the patient was alarming for potential subsequent lead poisoning due to retained pellets.

Dispersion of QT and QTc interval in healthy children, and effects of sinus arrhythmia on QT dispersion.

OBJECTIVE: To determine the normal values of QT and QTc dispersion and the effects of sinus arrhythmia on QT dispersion in healthy children. PATIENTS AND SETTING: The study was carried out in a university hospital on 372 local schoolchildren (200 male, 172 female), aged seven to 18 years. METHODS: The QT and preceding RR intervals of at least one sinus beat were measured manually in a range of nine to 12 leads on standard 12 lead surface ECGs. The corrected QT interval was computed by the method of Bazett. Dispersion of QT and QTc were defined as (1) the difference between the maximum and minimum QT and QTc intervals occurring in any of the 12 leads (QTD and QTcD), (2) the standard deviation of the QT and QTc interval in the measurable leads (QT-SD and QTc-SD). RESULTS: There was no significant difference in QT, QTc, and RR dispersion between girls and boys. Overall 53% of children had sinus arrhythmia. Although QTD and QT-SD were not affected by sinus arrhythmia, both QTcD and QTc-SD were significantly greater in children with sinus arrhythmia than in those without (QTcD: 52.9 (17.4) v 40.9 (13.1); QTc-SD: 17.5 (5.9) v 13.2 (4.0); p < 0.001). CONCLUSIONS: As calculation of QTc dispersion is affected by sinus arrhythmia, which is common in childhood, we suggest that QT dispersion should not be corrected for heart rate in children.

Congenital isolated apical ventricular septal defects.

The diagnosis of apical ventricular septal defects (VSDs) is difficult and the ratio of spontaneous closure is not well known. At the Ankara University Pediatric Cardiology Department, between the years 1992 and 1997, 33 patients were identified by color-flow Doppler (CFD) imaging as having a small defect at the apical portion of the ventricular septum. The age range was 1 day to 13 years. All patients were asymptomatic with normal telecardiograms and electrocardiograms. There were grade 2-3/6, pansystolic murmurs at the apex or closer to the apex in 19 patients. In 30 patients, narrow and short colored jets were seen at the apex of the heart, distal to the moderator band. The jets were wide in three patients. These defects were difficult to image and required specific angulation of the transducer. Of the 23 patients who had follow-up examinations, at 3 months to 3.5 years, there was spontaneous closure in ten (43.5%). To the authors' knowledge, this report is the largest series of isolated apical trabecular ventricular septal defects (t-VSDs). In their experience, color-flow imaging is more sensitive in detecting a small apical VSD. They conclude that although the closure of apical VSD is not the rule, the prognosis is excellent.

Congenital complete atrioventricular block in an infant with long QT syndrome.

A three months old patient with congenital complete atrioventricular block and prolonged QT interval syndrome is presented. Before admission she had had two syncopal attacks. During hospitalization she had an episode of torsade de pointes which was followed by ventricular fibrillation. After a successful cardiopulmonary resuscitation, a permanent epicardial ventricular pacemaker was implanted and she was discharged on propranolol therapy. She is now free of symptoms and doing well, 16 months after discharge.

Mitral valve and left ventricular thrombi in an infant with acquired protein C deficiency. A case report.

The authors present an infant with left ventricular and mitral valve thrombi diagnosed by cross-sectional echocardiography. Thrombosis was due to acquired transient protein C deficiency, which was caused by impaired liver function due to sepsis. Because the thombi were very large and mobile, urgent surgery was performed. Eight weeks later, the patient's protein C level returned to normal ranges. The authors suggest that in all cases with intracardiac thrombosis, protein C deficiency should be investigated.

Acute rheumatic fever in children in the Ankara area in 1990-1992 and comparison with a previous study in 1980-1989.

Two hundred and twenty-eight patients with acute rheumatic fever (ARF), who were admitted to Dr Sami Ulus Children's Hospital between January 1990 and November 1992, were evaluated. Compared with the 1980s, an increase in the frequency of the disease was observed. The majority of patients (56.5%) were between 9 and 12 years old and 36.8% were admitted in winter. One hundred patients had arthritis only, 59 carditis and 40 chorea; 5 had carditis and chorea and 24 had arthritis and carditis. Nineteen percent of patients had a history of a previous attack. Seven of 84 patients with carditis had congestive heart failure and 2 had pericarditis. Cardiomegaly was present in 36 patients. The mitral valve was affected in 77 patients, tricuspid valve in 1 patient and both miral and aortic valves in 6 patients. One patient died as a result of severe congestive cardiac failure. Twenty-one patients had a recurrent attack. We observed that ARF is still a significant cause of morbidity in our country. As the disease is preventable by the eradication of streptococcus, we conclude that more effort should be made in the early detection and treatment of streptococcal infections.

Fluid retention and cardiomegaly associated with carbamazepine in an epileptic child.

Carbamazepine (CBZ) has been reported to have an antidiuretic action, though it is not known how it produces this effect. This is a well recognized complication of CBZ therapy in adults. However this syndrome has been rarely observed in childhood. We present an epileptic child with fluid overload due to CBZ treatment who was referred with chest pain and cardiomegaly. Our patient developed fluid retention with cardiomegaly during treatment with CBZ alone at a normal dose and for a short time. To our knowledge this is the first case of the syndrome of inappropriate antidiuretic hormone secretion (SIADH) due to CBZ therapy which has been observed to be associated with cardiomegaly.

Congenital heart disease and Robinow syndrome.

We present a 6-month-old infant with Robinow syndrome and tricuspid atresia (type Ia). Up to now, at least 67 cases of Robinow syndrome have been published including nine cases with a congenital heart defect (CHD). As in our case, the majority of the CHD were right ventricular outflow obstruction. Robinow syndrome with CHD is not rare and in all cases of Robinow syndrome detailed cardiologic evaluation and echocardiography should be performed.

Gaucher's disease with mitral and aortic involvement: echocardiographic findings.

Cardiac involvement in Gaucher's disease has been reported in only a few patients, mostly adults with pericardial changes. We describe findings in two siblings with Gaucher's disease, aged 15 and 9 years respectively, in whom mitral and aortic valve lesions were evaluated by auscultation and echocardiography. In both cases the mitral and aortic valves were thick and restricted in motion. Continuous Doppler echocardiography revealed significant mitral regurgitation and mitral stenosis. At the aortic valve level there was a systolic pressure gradient. Echocardiographic investigation of patients with suspected cardiac involvement with Gaucher's disease is recommended.

Two-dimensional echocardiographic diagnosis of tricuspid valve noninfective endocarditis due to protein C deficiency (lesion mimicking tricuspid valve myxoma).

Noninfective endocarditis may develop on heart valves in a wide variety of clinical conditions. Various events have been cited as possible etiologic factors. These lesions are clinically important because the vegetations frequently embolize and cause arterial obstruction and tissue infarction. Previously, the diagnosis of the disease had been made only at autopsies. Only a single case has been reported to have been diagnosed clinically in childhood. We present a patient with noninfective endocarditis, urgently operated on with the presumptive echocardiographic diagnosis of tricuspid valve myxoma, whose protein C level was found to be very low. It's known that in patients with homozygous congenital protein C deficiency venous thrombosis may develop. We think that the etiologic factor of the thrombosis on the tricuspid valve in the case presented is congenital protein C deficiency. With this case study we further emphasize the specific role of two-dimensional echocardiography in the diagnosis of noninfective endocarditis and recommend that protein C deficiency be investigated as an etiologic factor.

Cardiac rhabdomyoma in a newborn two-dimensional echocardiographic diagnosis.

Primary cardiac tumors are quite rare in the newborn period. Prior to surgery, cardiac catheterization and angiocardiography have been performed to confirm the two-dimensional echocardiographic findings. In this report a 2-day-old baby with the clinical impression of severe cyanotic congenital heart disease diagnosed by two-dimensional echocardiography as multiple rhabdomyoma and confirmed by surgery is presented. It is emphasized that two-dimensional echocardiography is a very useful technique for the diagnosis of primary cardiac tumors. By means of this method severely symptomatic newborns may be taken directly to surgery without prior cardiac catheterization, thus minimizing complications.

[An outbreak of influenza in hospital personnel].

During the last week of December 1989, an outbreak of respiratory system infection involved 32 hospital personnel and 2 patients was detected in Gazi University Medical Faculty Hospital. White blood cells count of the patients were either normal or there were a slight leucopenia. Throat cultures of the most patients were normal. Serum ASO, CRP, bilirubin, AST and ALT were usually within normal limits. According to symptoms, signs and laboratory data we considered a viral disease, especially influenza. All patients recovered without any sequelae. Of 34 in-patients, 8 paired sera, 2 acute phase sera, and 10 convalescent phase sera were tested for the presence of Hemagglutination Inhibition (HI) antibody to three influenza virus strains recommended by WHO in the 1989-1990 season: Influenza A/Taiwan/1/86 (H1 N1), Influenza A/Shanghai/11/87 (H3 N2), Influenza B/Victoria/2/87. All of the sera were negative for Influenza B/Victoria/2/87. There were no significant rises in HT antibody titer for Influenza A/Taiwan/1/86 (H1 N1). The sera for 4 of 8 patients examined both acute and convalescent phase sera had fourfold or greater rise in HI antibody for Influenza A/Shanghai/11/87 (H3 N2). Four patients examined only convalescent sera had 1/40 or greater rises in HI antibody for this influenza subtype. It was considered that this influenza outbreak was probably caused by Influenza A/Shanghai/11/87 (H3 N2).

[Bacteriological comparison of colostrum and mature human milk].

15 colostrum and 15 mature milk were examined in bacteriology laboratory in Ankara Numune Hospital. The number of colonies cultured at "0" hour, 6-24 after at room temperature 24 after refrigeration were evaluated. It was noticed that the cultures obtained at 0 and 6 hours and after refrigeration did not reveal much bacteria. But cultures obtained from Colostrum and mature milk after 24 hours at room temperature revealed colonies. The colonisation in mature milk was significantly higher than the colostrum.
