Pulmonary oedema following choking: report of two cases.

Two children, aged 3 1/2 and 5 1/2 years, are described. Both developed pulmonary oedema (PE) following a short episode of choking on a sweet and an orange, respectively. On admission diagnosis was made by chest X-ray. One child was asymptomatic despite PE while the other showed only mild respiratory distress. Both children recovered spontaneously and chest X-rays showed a return to normal within 24 h. The mechanism of PE production is discussed. It is suggested that oedema formation occurs during the obstruction and that it is due to hypoxia and the severe negative pleural pressure resulting from attempts to inspire against the obstructed airway. both hypoxia and severe negative pleural pressure cause an increase in pulmonary capillary pressure and transduration of fluid across the capillary membrane.

Rib osteomyelitis in children. Early radiologic and ultrasonic findings.

The earliest radiographic changes of osteomyelitis in the long bones is deep-seated edema manifesting as soft tissue swelling and obliteration of the intermuscular planes adjacent to the affected bone. Similarly, the early change of rib osteomyelitis is pericostal edema demonstrated by soft tissue swelling of the thoracic wall accompanied by an adjacent inward pleural displacement. In both osteomyelitis of the rib and the long bones, the bony changes will appear 1-2 weeks later. Pericostal edema can be readily diagnosed by ultrasound scan. Pericostal edema, although non specific and can occur in other conditions, yet it is a strong warning sign, set within the overall clinical picture of osteomyelitis.

Recurrent suppurative thyroiditis due to fourth branchial pouch sinus.

Acute suppurative thyroiditis is a rare disease in childhood. The etiology of this condition is not always obvious. The description of a pharyngeal pouch fistula extending from the pyriform sinus to the thyroid gland or perithyroid area, high-lighted the etiopathogenesis of some of the thyroiditis cases. Presented here are the clinical, radiological and pathological aspects of an internal pharyngeal fistula manifesting with recurrent suppurative thyroiditis, until it was completely removed. The clinical features of caudal branchial pouch remnants and their role in the development of acute suppurative thyroiditis is reviewed.

Familial meconium ileus with normal sweat electrolytes.

Meconium ileus (MeI) is the presenting symptom in 10 to 15 percent of infants with cystic fibrosis (CF), but it is a rare phenomenon in patients who do not have this disease. We report four Bedouin siblings who had MeI with no laboratory evidence of CF.

Fiberoptic bronchoscopy in patients with hemoptysis and nonlocalizing chest roentgenograms.

We reviewed retrospectively the records of 45 patients undergoing fiberoptic bronchoscopy for hemoptysis in whom chest roentgenograms either were normal or showed only nonlocalizing findings. Follow-up was available for up to three years. In none of the patients was evidence of malignant neoplasms found either at the time of the initial evaluation or at the time of follow-up. This was true for all age groups and for smokers as well as nonsmokers. We conclude that routine fiberoptic bronchoscopy for hemoptysis is not necessarily indicated in patients like ours. Indications for this procedure in this type of case should be carefully weighed.

Cervical spine involvement in familial Mediterranean fever.

We report a case of familial Mediterranean fever (FMF) complicated by nephrotic syndrome and renal failure due to amyloidosis. This case is unique in that the severity of joint involvement necessitated bilateral hip replacement and later caused cervical apophyseal joint fusion, the latter being a lesion not previously described in the course of FMF.

Chronic multifocal symmetrical osteomyelitis. Report of two cases in Bedouin infants.

Chronic multifocal symmetrical osteomyelitis is a rare condition characterized clinically and radiologically by multiple symmetrical bone lesions, a benign course, and a good prognosis. To our knowledge, only 25 cases have been reported in the literature; all of them occurred in patients of European ancestry. We describe two bedouin children, aged 20 and 21 months, who suffered from this disease. Although they complained of one painful joint, multiple osteolytic lesions were found in the long bones. At follow-up six months later, the children were in perfect condition without radiologic sequelae.

Pulmonary edema secondary to chronic upper airway obstruction. Hemodynamic study in a child.

A 22-month-old girl with the syndrome of hypoventilation, pulmonary hypertension, cor pulmonale and pulmonary edema due to adenoidal hypertrophy is described. Adenoidectomy resulted in relief of all symptoms and signs within 24 h. Hemodynamic study using pulmonary artery catheter showed that the pulmonary artery pressure returned to normal 48 h after relief of the obstruction. The normal left ventricular end-diastolic pressure, measured throughout the period of obstruction, in the presence of severe pulmonary edema, could suggest a non-cardiogenic "low pressure" pulmonary edema. However, the highly negative pleural pressure which existed during upper airway obstruction indicated an elevation of transmural left ventricular end diastolic pressure (compared to pulmonary wedge pressure) and thus, suggested that the pulmonary edema in this syndrome is secondary to both - right and left heart failure.

Widespread osteolytic lesions of the long bones in basal cell nevus syndrome.

Three members of a family, father, daughter, and son, with the basal cell nevus syndrome are presented. A very unusual manifestation of widespread cyst-like osteolytic lesions in all the tubular bones was observed in the father, together with osteoblastic spotty "osteopoikilotic" lesions in the skull and the mandible of the same patient. Cyst-like osteolytic lesions have been described previously in this syndrome, mainly in the phalanges. We believe that such lesions can occur in any bone.

Necrotizing enterocolitis beyond the neonatal period.

Necrotizing enterocolitis (NEC) is usually considered to be a neonatal disease, and is rarely described beyond the newborn period. During the last 15 years, 19 infants from the Negev region, Israel, with NEC were beyond the neonatal age group (range = 34-616 days, median = 90 days). Of this group only 16% were born prematurely, and only 16% had perinatal or neonatal pathology. Diarrhea and dehydration preceding NEC were common as was malnutrition. Bacteremia was detected in 42%. The mortality rate was 90%. Malnutrition, supposedly contributed to the formation of NEC and to the high mortality rate among these infants.

Residual small airways lesions after kerosene pneumonitis in early childhood.

To assess residual lung damage after a single insult early in life, we studied 14 asymptomatic children, 10 years after an episode of kerosene pneumonitis. Immediately after kerosene ingestion all patients developed pulmonary symptoms. Eight had abnormal chest radiographs (group 1) whereas in six there were no radiographical changes (group 2). The average age at follow-up was 11.4 (range: 9.4-13.2). Lung volumes, expiratory flow-rates and their density dependence were measured and compared to an age, sex, and a height-matched control group. The volume of isoflow (Viso V) was significantly higher in patients in group 1 (27.75% +/- 6.7) when compared to group 2 (5.48% +/- 3.56) or controls (5.63% +/- 2.31) (P less than 0.02). The mean delta V max 50 was 13.5% +/- 3 for group 1, and 27.9% +/- 4.11 for group 2 (P less than 0.005). Airway reactivity assessed by an exercise test was normal in all children. Four of the eight patients from group 1 still had abnormal chest radiographs 10 years after kerosene pneumonitis. Thus, subclinical, prolonged small airway abnormalities after kerosene pneumonitis seem to be related to the severity of the acute insult.
