Transient right sided hypertrophic cardiomyopathy in an infant born to a diabetic mother.

Hypertrophic cardiomyopathy (HCM) is a rare primary myocardial disease, characterized by hypertrophy of the left and/or right ventricle. Infants of diabetic mothers (IDM) are at risk for development of HCM, respiratory distress and persistent pulmonary hypertension. A case of severe right sided HCM in an infant born to a diabetic mother is presented. The patient's findings were complementary to the previous observations reporting HCM in IDM. The presence of disproportionate septal hypertrophy in the echocardiography of an infant born to a diabetic mother is highly suggestive of HCM in IDM. In our opinion, further cardiac evaluation is not indicated unless other cardiac abnormalities are suspected.

Assessment of clinical impact and predisposing factors for neonatal thrombocytopenia.

Thrombocytopenia is a common hemostatic abnormality in the newborn infant. The early diagnosis of thrombocytopenia and the underlying primary pathology process play an important role in reducing the risk of severe complications and mortality. We performed a 2-year prospective study of 643 neonates admitted to our neonatology unit to determine the frequency, predisposing factors, and clinical impact of thrombocytopenia. Thrombocytopenia developed in 18.2% of the preterm neonates and 0.8% of the term neonates. Prematurity, sepsis, hypoxia, intrauterine growth retardation, and disseminated intravascular coagulation were identified as predisposing factors for thrombocytopenia. The incidence of complications and mortality were higher in thrombocytopenic infants. Especially the prognosis was worse in cases who had mucosal hemorrhage, without a relation with the degree of thrombocytopenia. The thrombocytopenia occurred by day 2 in 43% of the infants, and resolved by day 8 in 61%. The platelet count nadir occurred by day 2. Since thrombocytopenic infants are at greater risk for bleeding, and the thrombocytopenia itself may have contributed to the high mortality, predisposing factors such as prematurity, infections, hypoxia must be eliminated by providing better care, giving adequate hygiene of both mother and the baby during the prenatal, natal, and neonatal period.

Breast milk versus infant formulas: effects on intestinal blood flow in neonates.

The differences between breast milk and infant formulas have been a popular subject of many recent studies. Most concern the chemical and biological characteristics of breast milk and infant formulas, but little work has been done about hemodynamic changes in the splanchnic circulation. In term neonates (n = 22) we evaluated the effect of breast milk, adapted cow's milk formula, and nucleotide supplemented cow's milk formula on intestinal blood flow. To determine the blood flow velocity and estimate volume flow, pulsed Doppler ultrasound of the superior mesenteric artery (SMA) was performed prefeeding and 15, 45, and 90 minutes following feeding. When pre- and postprandial blood flow features of babies were compared among in their groups according to nutrition post prandial blood flow velocity and volume flow were increased significantly over baseline in all three groups. While there was no significant difference between the postprandial blood flow parameters of the breast milk and adapted cow's milk formula-fed groups, the nucleotide supplemented cow's milk formula-fed group had significantly higher postprandial blood flow velocity and volume flow.

Kawasaki syndrome.

Kawasaki syndrome, also known as mucocutaneous lymph node syndrome, is an acute vasculitis of infants and young children. We describe a four-year-old girl who presented with fever, a diffuse erythematous maculopapular rash, bilateral nonpurulent bulbar conjunctivitis, dry, red, fissured lips, a tongue with a strawberry "appearance", an erythematous pharynx, indurative erythema, and edema and desquamation of the face, hands and feet. She probably developed mitral valve prolapse during the course of the disease. The diagnosis of Kawasaki syndrome was arrived at by excluding other diseases and by the presence of all the clinical criteria for Kawasaki syndrome. Since this syndrome is rarely encountered in Turkey, this case is presented and the literature regarding the syndrome is reviewed.

A case of common truncus arteriosus with rare cardiac abnormalities.

Truncus arteriosus communis is a well-known, congenital, cardiac abnormality. In this report, we describe a very rare variant in which the truncus arose from the right ventricle, the atrial and ventricular septa were intact, the left ventricle was hypoplastic and the small right atrium was draining to the truncus arteriosus through a fibrose tunnel-like connection.

A case of mixed gonadal dysgenesis with 45 X/46 XY karyotype and aortic coarctation.

We report a case of mixed gonadal dysgenesis with 45 X/46 XY karyotype and aortic coarctation. An eight month-old patient was admitted to our endocrinology department for evaluation of ambiguous genitalia. On physical examination, a wide neck with a low posterior hairline, bifid scrotum, small phallus, testis in the right labioscrotal fold, single orifice and typical findings of aortic coarctation were present. The chromosome karyotype of the patient was 45 X/46 XY. On the laparotomy there was an infantile uterus, fallopian tubes, and a streak gonad on the left. The follow-up of the patient included sex assignment, genital reconstruction and cardiovascular treatment.

Juvenile rheumatoid arthritis: cervical spine involvement and MRI in early diagnosis.

Magnetic resonance imaging (MRI) of the cervical spine was performed on 20 patients (mean age 10 years) with a preliminary diagnosis of juvenile rheumatoid arthritis (JRA). In all patients conventional x-rays of the cervical spine were obtained, and the relationship between clinical status and MRI findings were evaluated. Two patients with clinical manifestations, including neck pain and diminished range of motion, exhibited significant pathologic features on radiogram and MRI, the latter providing more detailed information. Among 18 patients who had no complaints about their cervical spines, 3 patients (65%) had either soft tissue involvement, pannus formation or erosions on the surface of atlantoaxial joints; only four patients (20%) had erosions on plain x-ray views. Since the early diagnostic ability of MRI in JRA allows early therapeutic intervention, every patient with a probable diagnosis of JRA would benefit from MRI.
