Intrathoracic kidney.

Intrathoracic kidney is a rare congenital anomaly. However, it should be included in the differential diagnosis of posterior mediastinal masses, as confirmation of the diagnosis obviates the need for further clinical studies, further treatment, and unnecessary surgery. Chest computed tomography (CT) is an important and efficient tool in confirming the diagnosis. We report a 50-year-old man who suffered from nonspecific chest pain for 2 years. He denied a history of major traumatic chest injury. Chest radiograph revealed a left posterior mediastinal mass, which was later confirmed by chest CT to be a congenital intrathoracic kidney.

Estimation of prevalence and incidence of infantile spasms in Taiwan using capture-recapture method.

PURPOSE: To estimate the prevalence, incidence, and case-fatality of infantile spasms (IS) in Taiwan. METHODS: A retrospective cohort of patients with IS was obtained from one medical center to identify 69 IS cases from 1985 to 1997. This cohort, in conjunction with the claimed data from the National Health Insurance, was used to estimate the prevalence and incidence of IS by capture-recapture design, taking the case-fatality of IS into account. RESULTS: The prevalence rate of IS for aged 0-9 years was 0.046 per thousand. The incidence rate was estimated as 6 over 100,000 per year in Taiwan. Of the 69 IS cases, 8 deaths were ascertained. The case-fatality rate was 11.6%. The leading cause of death was status epilepticus. CONCLUSIONS: We have demonstrated an efficient method to estimate the incidence and prevalence rates of IS in Taiwan. Our results help to make a clear understanding of the disease burden of IS in this society.

Diffuse alveolar damage associated with ticlopidine use: a case report.

Ticlopidine-induced lung disease is rare. A 52-year-old man with acute myocardial infarction developed respiratory distress 2 days after receiving ticlopidine for coronary artery stenting. The dosage of ticlopidine was 500 mg orally followed by maintenance of 250 mg twice daily. Chest radiography revealed bilateral haziness predominantly over upper lung fields. He did not respond to treatment for suspected cardiogenic lung edema and mechanical ventilation was instituted. Open lung biopsy documented diffuse alveolar damage. After discontinuing ticlopidine and treatment with systemic corticosteroid, his pulmonary condition improved gradually. Within 2 weeks, the patient was successfully weaned from the ventilator. Although rare, diffuse alveolar damage is a potential side effect of ticlopidine treatment and should be included in the differential diagnoses of heart failure patients taking ticlopidine who respond poorly to optimal therapy.
