[Primary pulmonary aspergilloma presenting as an isolated nodular shadow].

A 55-year-old man was admitted to our hospital because of an abnormal shadow at the right hilum on a chest radiograph. The chest radiograph and the chest CT scan showed a nodular showed in the right S6. There was no air-crescent sign in the shadow, but CT-guided percutaneous needle biopsy led to the diagnosis of pulmonary aspergillosis. Anti-fungal agents (miconazole, fluconazole, and itraconazole) were given but the patient's condition did not improve. Surgical resection was done and the postoperative course was uneventful. The resected lung had a bronchiectatic area with a fungus ball. Attempts to culture the fungus ball were not successful. Histologic examination revealed conidial heads characteristic of Aspergillus fumigatus. This case is interesting because the pulmonary aspergilloma appeared as an isolated nodular shadow. This might have been a case of primary pulmonary aspergilloma.

[Chronopharmacology and chronotherapy for asthma by using PEF].

Several attempts have recently been made to develop chronotherapy for nocturnal asthma, using theophylline, inhaled corticosteroid, inhaled anticolinergic agent and beta 2-agonist. Pharmacological chronotherapy is the administration of medication according to biological rhythm to maximize pharmacological effects and minimize side effects. The circadian rhythm of biological rhythms is particularly important in understanding the declined changes in lung function of asthmatics at night. Since diurnal variations of PEF obtained from asthmatics, include circadian rhythms at a high rate, it is thought that PEF may be suitable for evaluating the effect of chronotherapy. Chronotherapy of a once-daily evening dose of a new controlled-release theophylline preparation, that achieves to peak blood concentrations at 10-12 hours after dosage, effectively improved the values of PEF and symptoms of nocturnal asthmatics. Hereafter, it is speculated that more effective therapy will be developed by using chronopharmacological designed drugs.

[Respiratory function in students who had asthma in childhood].

Students who had asthma in childhood can be divided into three groups: "asthma-remission" group "asthma-relapsing" group and "non-asthma-remission" group. When we made inquiries about three different groups, the incidence of each group was 58%, 27% and 15%, respectively. In order to determine if childhood asthma affects respiratory function in adulthood, we measured respiratory functions by spirometry in 26 students who had asthma in childhood, and in seven control students. There was no significant difference between students with childhood asthma and control students in terms of FEV1.0% of predicted value. However, students who had asthma in childhood had lower levels of V25/HT% of predicted value in comparison with control students. The effects of deep inhalation in the three groups were evaluated by determining the values of maximal expiratory flow at 40% (MEF40) of vital capacity from partial (P) and maximal (M) flow-volume curves. There was no difference between the remission group and the control group in the MEF40 M/P ratio. This suggests that childhood asthma may deteriorate respiratory functions in adulthood by remodeling of peripheral airways.

[A case of left intrathoracic kidney with renal anomalies].

A rare case of intrathoracic kidney was reported. A 71-year-old female with no complaint presented for evaluation of an abnormal shadow in the left lung field. A routine chest roentgenograms showed a sharply outlined mass in the postero-medial portion of the left lung field. Computed tomography demonstrated left intrathoracic kidney with anomalies of rotation. Intravenous pyelography demonstrated a left high ectopic kidney with complete duplication of the renal pelvis and incomplete duplication of a ureter. The patient was diagnosed as left intrathoracic kidney with renal anomalies. The 79 cases of intrathoracic kidney reported in Japan were analyzed concerning their etiology.
