Use of an appendicitis medical information sheet in the pediatric primary care system.

BACKGROUND: Accurate and prompt diagnosis is required for the primary evaluation of pediatric appendicitis. Among pediatricians and surgeons working in Yamanashi Prefecture, the pediatric appendicitis medical information (PAMI) sheet was edited in April 2011 to reflect the diagnostic results of the pediatric primary and emergency medical service and used as a referral document for surgical consultation to secondary hospitals. METHODS: The PAMI sheet consisted of sections for history taking, symptoms, physical signs and laboratory findings without a scoring system. For 32 consecutive months starting in April 2011, 59 patients hospitalized for suspected appendicitis were retrospectively reviewed. In particular, a total of 17 referral patients evaluated with the PAMI sheet were assessed in order to evaluate the utility of the form. RESULTS: The pediatric surgeons were able to easily determine patient condition from the PAMI sheet. In total, 13 of 17 patients had appendicitis. According to the physical findings of the 17 studied patients, the judgment of right lower quadrant tenderness (κ = 0.63) and guarding (κ = 1.00) was consistent between the pediatric surgeons and primary attending pediatricians. CONCLUSIONS: The PAMI sheet aids in the collection of detailed history and objective data with a high level of accuracy, and provides useful referral diagnostic information to the secondary-level hospitals.

Thyroglossal duct cyst accompanied by laryngomalacia and pulmonary sequestration.

A 2-month-old full-term female infant developed nasal stridor, which progressed to respiratory distress and poor sucking ability. Direct pharyngoscopy showed laryngomalacia and a midline cystic mass in the lingual region. The mass pressed on the epiglottis, causing dyspnea. Computed tomography incidentally revealed extralobar pulmonary sequestration. Direct deroofing of the lingual cyst and plication of the epiglottis were performed at 3 months of age, and the patient recovered from the respiratory distress. Histopathology of the cystic mass showed a thyroglossal duct cyst. Thoracoscopic resection of the pulmonary sequestration was then done at 17 months of age. Thyroglossal duct cysts in the lingual region may cause destabilization of the epiglottis and laryngomalacia, resulting in acquired respiratory obstruction. The combination of thyroglossal duct cyst, laryngomalacia, and pulmonary sequestration is rare; therefore, reports must be accumulated in order to explore the embryological origins of such cases.

Severe hypothalamopituitary dysfunction accompanied by influenza-associated encephalopathy: report of two pediatric cases.

Severe influenza infection may lead to neurological damage, such as encephalopathy. This may, in turn, cause acquired hypothalamopituitary dysfunction, which can result in severe morbidity and even death. We herein report two pediatric patients who developed influenza-associated hypopituitarism and were subsequently diagnosed with encephalopathy. They were diagnosed with acute necrotizing encephalopathy and postresuscitation encephalopathy, respectively. Both showed evidence of endocrine dysfunction, and hormone replacement therapy of adrenal, thyroid, and antidiuretic hormones are resulting in continued cardiac activity and resulted in prolonged survival. Screening for endocrine function is important in patients with severe central nervous system dysfunction.

A case report of dysosteosclerosis observed from the prenatal period.

Dysosteosclerosis is a sclerosing bone dysplasia with skeletal changes resembling those of osteopetrosis. The disorder is associated with dental anomalies and occasionally mental retardation. Because of the rarity and phenotypic diversity of dysosteosclerosis, it remains unsolved whether or not the disorder is heterogeneous. We report here on an affected boy associated with brain calcification and epilepsy with developmental delay. Prenatal ultrasound revealed ventriculomegaly, and brain CT in the neonatal period showed periventricular calcifications. At 13 mo of age, he presented with generalized convulsion with developmental delay. Metaphyseal sclerosis, metaphyseal undermodeling, and oval-shaped vertebral bodies on skeletal survey warranted a diagnosis of dysosteosclerosis. Retrospective review of radiographs as a neonate showed metaphyseal radiolucency, but not metaphyseal sclerosis. Since then, neither the bone changes nor neurological symptom has progressively worsened up to 4 yr of age. Thus, it is thought that the clinical and radiological manifestations of the sclerotic disorder become obvious during infancy. Brain calcification of prenatal onset may be an essential syndromic constituent of the disorder.

Accessory hepatic vein complicating extra-cardiac total cavopulmonary connection.

We encountered unexpected, severe hypoxia after the right heart bypass operation in a patient with isomerism. A 2-year-old girl with polysplenia had a complex cardiac anomaly consisting of a single atrium, single ventricle, pulmonary stenosis, absence of the right superior vena cava, hemiazygos continuation of the left inferior vena cava, and d-malposition of the great arteries. After a total cavopulmonary shunt, we performed an extra-cardiac total cavo-pulmonary connection with a 14 mm tube graft. The postoperative course was complicated by severe hypoxia. Angiography performed 20 days after the operation showed that contrast medium in the conduit poured into the hepatic vein, and through the intrahepatic communications, it passed into a left-sided accessory hepatic vein, which was connected directly to the left side of the aspect of the atrium. As the intrahepatic communication was adequate, we ligated the accessory hepatic vein within the pericardial cavity. The SpO2 returned to normal and no hepatic dysfunction was detected. We conclude that surgeons performing extra-cardiac total cavopulmonary connection need to pay closer attention to the possibility that an accessory hepatic vein might exist.
