The incidence of analgesics intolerance in asthmatic children detected by history and inhalation challenge with lysine acetylsalicylate.

To determine the incidence of adverse reactions to analgesics in unselected asthmatic children, histories were obtained from 486 children, using questionnaires and interviews. Mean age was 11.4 +/- 2.3 (+/- 1 SD) years (range 6-17 years), and mean duration of disease was 7.6 +/- 3.6 (1-15) years. The majority of 21 children gave an equivocal history, and only 7 (1.4%) of all children had a reliable history of adverse reactions to various analgesics. Inhalation challenge with increasing doses of lysine acetylsalicylate (LASA) was performed in 75 randomly selected asymptomatic children. Two boys of these (2.7%) had a positive test, defined as a 25% or more decrease of FEV1 and/or a 50% or more increase of the oscillatory airway resistance, compared with base line values. Both children had a mild airway obstruction, and had no personal or family history of analgesics intolerance. Further 27 children with suspected positive personal or family histories were also challenged. One girl of these manifested a mild urticaria; her pulmonary function remained unchanged. The incidence of analgesics intolerance in unselected asthmatic children is much lower than that of 12.5% to 28% reported in severe chronic asthma. The inhalation challenge with LASA proved simple, safe, effective and time saving, and thus, it offers an alternative method to the oral challenge in suspected children.

Juvenile dermatomyositis with respiratory failure and peripheral nerve paralyses. A case report.

A 9.5 years old girl suffering from an acute dermatomyositis, developed a respiratory failure, which was successfully managed with mechanical ventilation for 6 days. Paralysis of the right radial and the left peroneus nerves were recognized early in the disease course and were confirmed later by electrophysiologic examinations. A complete remission of the dermatomyositis and the paralysis of the radial nerve were achieved within months with prednisolone medication and physiotherapy; the peroneus nerve paralysis improved only slightly. Further uncommon manifestations were thrombocytopenia, retinitis and cerebral convulsions.

Pulmonary veno-occlusive disease, antiphospholipid antibody and pulmonary hypertension in an adolescent.

UNLABELLED: Pulmonary veno-occlusive disease (PVOD) is a rare cause of pulmonary hypertension (PH); Antiphospholipid antibody (APL) is another known cause of pulmonary hypertension, due to recurrent pulmonary thromboembolism. The coincidence of both causes, PVOD and APL, without thromboembolism, in PH has not been reported previously in children. A 12.5-year-old boy presented with a one year history of fatigue. Pulmonary hypertension was diagnosed by echocardiography. Pulmonary function tests revealed a moderate restrictive pattern and elevated granulocytes were detected in bronchoalveolar lavage. An isolated high-titer APL was detected. Open lung biopsy established the diagnosis of PVOD, with no evidence of pulmonary thrombosis, but with accompanying interstitial and alveolar cellular infiltration. We speculate that APL may have played a role in the pathogenesis of PVOD. Prednisone++ improved the symptoms of the interstitial pneumonitis and was stopped; on follow up of 30 months, the patient ist in stable condition on therapy with nifedipin, phenprocoumon and digoxin. CONCLUSIONS: PVOD and APL may be present simultaneously as a rare cause of PH. Interstitial pneumonitis may accompany PVOD and produce the leading symptoms. Open lung biopsy is essential for early establishment of the diagnosis.

[Isolated abnormality ("noncompaction") of the myocardium in 3 children].

UNLABELLED: In three asymptomatic children an isolated myocardial noncompaction was detected by echocardiography at age 11 months, 5 weeks and 5.5 years. In the first male infant both ventricles and septum were severely affected and myocardial function was depressed. Nevertheless, during a follow up of 16 months he remained asymptomatic on anticongestive therapy. In the other two children apex and lateral wall of the left ventricle were affected and myocardial function was still normal. The second boy had also an infantile epilepsy-encephalopathy syndrome and the third child (a girl) had a Wolff-Parkinson-White syndrome; an association of either syndromes with myocardial noncompaction has not been reported earlier. DISCUSSION: Myocardial noncompaction (spongy myocardium) is a rare maldevelopment, which occurs either associated with certain congenital heart defects or, even more rarely, isolated, as the two cases reported here. Myocardial failure, severe arrhythmias or thromboembolism may occur at any age and determine the outcome. Clinical course, therapy and prognosis are similar to dilatative cardiomyopathy, which represents an important differential diagnosis.

[Interstitial lung diseases with pulmonary hypertension associated with epidermolysis bullosa in an infant].

Interstitial lung diseases, with or without pulmonary hypertension and epidermolysis bullosa are rare in infancy. Pathogenetic correlations between these disease are not known and their coincidence has not been reported, yet. We report on a seven weeks old boy of consanguine parents with typical skin efflorescences of epidermolysis bullosa, tachydyspnoea and cyanosis. Echocardiography and cardiac catheterisation revealed pulmonary hypertension, which persisted under therapy with oxygen and nifedipin. Lung biopsy showed interstitial and peribronchiolar increased lymphocytes and lymphfollicels, a mild intraalveolar desquamation and a media hypertrophy of the arteries. A combined therapy of prednisone and nifedipine normalised the pulmonary hypertension and the oxygen saturation. The activity of the epidermolysis bullosa showed no correlation with the interstitial lung disease or with the therapy. A connection between both diseases is discussed.

Hypergammaglobulinemic purpura of Waldenström: report of 3 cases with a short review.

Benign hypergammaglobulinemic purpura of Waldenström (HGPW) is an uncommon cause of non-thrombocytopaenic purpura that may create diagnostic difficulties. The presence of constitutional symptoms associated with prominent immunological abnormalities may raise alarm, leading to extensive and often unnecessary investigations. This report describes 3 young women with HGPW. Clinical features were characterised by recurrent episodes of bilateral asymmetrical palpable purpuric lesions on the lower extremities that were precipitated by a prolonged increase in hydrostatic pressure (e.g. prolonged standing, tight stockings etc.) associated with constitutional features. In one patient the condition was secondary to Sjögren's syndrome with type IV renal tubular acidosis. Laboratory abnormalities included a persistently elevated erythrocyte sedimentation rate, marked polyclonal hypergammaglobulinemia, and high titers of rheumatoid factor and anti-nuclear antibody of the anti-SSA (anti-Ro)/anti-SSB(anti-La) subsets. This topic is reviewed briefly with the emphasis that in its 'primary' form this condition could be considered a 'benign' systemic immunoinflammatory disease that requires neither extensive investigations nor any aggressive form of therapy. Greater awareness of HGPW may increase the frequency of its diagnosis, especially in the patient group with non-thrombocytopenic purpura or the so-called cutaneous vasculitic syndromes with 'palpable purpura'.

[The significance of extra-articular manifestations for the differential diagnosis of musculoskeletal diseases in children].

Musculoskeletal complaints comprise about 7% of all pediatric office visits. The differential diagnosis of these complaints is very extensive. A great diagnostic aid offer quality, distribution and temporal course of the pain of joints, bone and muscles, of an objectively detectable arthritis, and especially of the numerous manifestations of other organ systems: Constitutional signs, fever, skin, mucous membranes, eyes, nervous system, heart, vasculature, lungs, digestive system and urogenital system. Combinations of these often early manifestations are crucial to determine the disease category, which is urgent for further diagnostic measures and for therapy: Bacterial, rheumatic, collagen-vascular, traumatic, orthopedic, and neoplastic disease. They are as important for making the final diagnosis and for the early recognition of later manifestations and complications. To achieve an optimal diagnostic efficiency, laboratory investigations should be carefully selected according to the clinical findings and diagnoses. A few regular investigations are valuable for the assessment of disease activity and therapy, and others for the early detection of initially asymptomatic manifestations.

Noninvasive measurement of regional lung water distribution in healthy man and in pulmonary oedema.

A quasi steady-state noninvasive, radioisotopic technique for measuring regional lung water distribution in man is described. The method depends upon the dilution principle. 123I labelled human serum albumin (HSA) and sodium iodide (NaI) were injected intravenously, allowed to mix completely within the body fluids and then counted externally over the chest. The size of each compartment to which the markers are confined was calculated from the external count rate and the isotopic concentration of the marker in plasma. 123I-HSA was used to estimate intravascular water and 123I-NaI extracellular water. Ratio analysis of the differential attenuation of the two photoenergies of 123Iodine (29 keV, 159 keV) by the lung and chest wall was used to estimate the absolute amount of isotope in the lung, independent of chest wall contribution, after validation by phantom studies. Regional pulmonary plasma (PPVr) and interstitial (PIVr) fluid volumes in normal subjects were 7.1 +/- 1.4 and 7.6 +/- 1.3 ml.100 cm-3 lung (mean +/- SD; n = 13) at mid-tidal volume, respectively. In patients with the adult respiratory distress syndrome, PPVr and PIVr were 7.0 +/- 2.9 and 15.9 +/- 4.6 ml.100 cm-3 lung (n = 18), respectively. The pulmonary artery wedge (Paw) pressure was normal (12.5 +/- 2.5 mmHg; n = 5). In patients with pulmonary oedema due to left heart disease, PPVr and PIVr were 7.2 +/- 2.7 and 12.1 +/- 3.7 ml.100 cm-3 lung (n = 8), respectively. The mean Paw pressure in this group was high (28.5 +/- 3.9 mmHg).
