Lung sound analysis in infants with risk factors for asthma development.

Background And Objectives: Using a lung sound analysis, the prognosis of asthma was investigated in infants with risk factors for asthma development by a long-term observation.

Methods: A total of 268 infants were included (median age: 8 months old). The lung sound parameters (the ratio of the third and fourth area to the total area under the curve [A/A and B/A], and the ratio of power and frequency at 50% and 75% of the highest frequency [RPF and RPF]) were evaluated at the first visit.

A Lung Sound Analysis in Infants with Risk Factors for Asthma During Acute Respiratory Infection.

The parameters of lung sounds have been suggested as biomarkers of airway changes. Using a commercially available lung sound analyzer, we investigated the characteristics of the lung sounds in infants with acute respiratory infection (ARI). Infants with ARI who were 6 to 18 months of age were included in this study.

Objective evaluation of wheezing in normal infants.

Background: To evaluate the frequency of wheezing in infants, the presence of wheezing was examined in normal infants using a breath sound analyzer, METHODS: A total of 443 infants (age range, 3-24 months) were included in the present study. The existence of audible wheezing and faint wheezing/inaudible wheezing-like noises (FW) was confirmed on chest auscultation and a sound spectrogram. The breath sound parameters of the sound spectrum, frequency limiting 99% of power spectrum (F ), roll-off from 600 to 1,200 Hz (slope) and spectrum curve indices, total area under the curve of dB data (A /A and B /A ), and ratio of power and frequency at 50% and 75% of the highest frequency of the power spectrum (RPF and RPF ) were calculated.

Characteristics of breath sound in infants with risk factors for asthma development.

Background: Breath sound parameters have been suggested as biomarkers of the airway narrowing in children. Using a commercially available breath sound analyzer, the characteristics of the airway condition were investigated in infants with the risk factors for asthma development.

Methods: A total of 443 infants (mean age, 9.

Acute allergic reaction due to milk proteins contaminating lactose added to corticosteroid for injection.

We encountered two patients with severe cow's milk allergy who reacted strongly to an injection of methylprednisolone sodium succinate (Sol-Medrol 40 mg Pfizer, Japan). They came to our hospital because of an asthmatic attack or urticaria and were treated with Sol-Medrol 40 mg. After the injection, the allergic reaction was immediate.

Perospirone augmentation of paroxetine in treatment of refractory obsessive-compulsive disorder with depression.

Obsessive-compulsive disorder (OCD) is often complicated by depression. We report on a patient with treatment-refractory OCD and treatment-refractory major depression who demonstrated a robust response to augmentation of paroxetine with perospirone. Perospirone is a second-generation antipsychotic agent with antagonist effects on both serotonin 5-HT(2A) and dopamine D(2) receptors, as well as a unique agonist effects on serotonin 5-HT(1A) receptors.
