Pulmonary blastoma is a family of tumors in which the glands or mesenchyme composing the neoplasm are primitive or embryonic in appearance. There are three subtypes, which include well differentiated fetal adenocarcinoma (pulmonary endodermal tumor), biphasic pulmonary blastoma, and cystic and pleuropulmonary blastomas in children. Among them, biphasic pulmonary blastoma is a primary malignancy of the lung originating from multipotential pulmonary blastema including both the malignant fetal epithelial and mesenchymal components. These make up 0.25 to 0.5 percent of all primary malignant lung tumors. This tumor is usually symptomatic and appears as a large, solitary peripheral mass, with a tendency to favor the upper lobe. Here we report a case where small sized asymptomatic peripheral lung mass was diagnosed as a biphasic pulmonary blastoma, prior to the operation, A subsequent percutaneous needle biopsy was performed, which revealed features of a large cell neuroendocirne tumor. In addition, a review of the relevant literature is provided.

PURPOSE: The purpose of this study was to investigate the effects of combined training using proprioceptive neuromuscular facilitation (PNF) patterns and treadmills on the balance and walking ability of stroke patients. METHODS: Twenty-three stroke patients were randomized into a control group (n=11), receiving only treadmill training and an experimental group (n=12) receiving combined training. The use of both PNF exercise and treadmill were implemented in the combined training. Interventions were performed 5 times a week for 6 weeks. Balance ability was measured by a timed up and go (TUG) test. Walking ability was measured by a 10-meter walk test (10MWT) and a 6-minute walk test (6MWT). A paired t-test was used to compare differences between pre- and post-intervention and independent t-tests were used to compare between groups. RESULTS: Changes in TUG, 10MWT, and 6MWT before and after interventions were significantly different for both the experimental group and the control group (p < 0.05). In addition, within-group changes in the TUG, 10MWT, and 6MWT were more effective in the experimental group than in the control group (p < 0.05). CONCLUSION: Combined training using PNF techniques and treadmills may be useful in improving the balance and walking ability of stroke patients.

OBJECTIVES: The multiple sleep latency test (MSLT) is commonly used as a valid objective measure of sleepiness. The procedure of MSLT is well standardized but the sleep onset criterion is somewhat variable. One epoch of stage 1 sleep is the most commonly used criterion, and the criterion of three epochs of stage 1 sleep is also used. The purpose of this study was to compare the two criteria used to determine sleep onset. METHODS: We retrospectively analyzed 60 consecutive MSLT that were performed according to a standaridized protocol. We scored each test using the two different criteria for sleep onset and then statistically analyed the results. RESULTS: Using the different criteria, 20 patients among 60 showed changes in mean sleep latency (33.3%). The extent of change ranged from 1.3% to 38.5% (mean 15.9%). Non-narcoleptic patients showed a significantly higher incidence of change than other sleep disorder patients. CONCLUSION: Changes in mean sleep latency occurred according to the different criteria of sleep onset. But the difference arising from different criteria was statistically not significant in patients with moderate to severe sleepiness. Considering that 1 epoch criterion for sleep onset is more sensitive in detecting clinically significant sleepiness, the authors suggest that the 1 epoch criterion is more reliable than the 3 epochs criterion.

Intussusception which is the mot frequent cause of intestinal obstrucsion in childhood, is the invagination of a segment of the gastrointestinal tract into an adjacent segment. Since 1927, barium enema under fluoscopic guidance has been used widely as a therapeutic method. In 1953, Fiorito and Cuestas reported the use of controlled insufflation of air for diagnosis and treatment of intussusception. This method has several advantages than barium enema for diagnosis and treatment, with its simplisity, fast diffusion of air, clear-cut visualization of intussusception, no contraindications, and no interference with the normal physiology of bowel. We compared the results of treatment with barium enema in 117 cases with that of controlled air insu-fflation in 50 cases from January, 1976 to Octover, 1981. The results were summarized as follows 1) Age and sex distribution of the overall cases: 82% of the patients were under 1 year of age(the peak incidence was 4~8 months of age) with the predominence of male(2.2:1). 2) Growth percentile comparing with Korean standard data: 67% of the patient were above 50 porcentile. 3) Seasonal incidence: slight prevalence was noted during spring, but not significant. 4) Etiologic factors: 97% of the patient were idiopathic and only 3% of the cases had organic causes. 5) Cardinal symptoms and signs: abdominal pain and irritability 82%, vomiting 76%, bloody mucous stool 64%, and abdominal mass 50.3%. 6) The most common type of intussusception is ileo-colic. 7) Reduction rate: 68.4% for barium enema and 92% for controlled air insufflation(p<0.01). 8) Recurrence rate: 12.5% for barium enema and 8% for controlled air insufflation. 9) Recurrence interval of overall cases is the most frequently from one month to 6 months after reduction. 10) Perforation: One case with barium enema and 2 cases with controlled air insufflation. 11) Duration and pressure requiring to reduce by controlled air insufflation: 84.8% of cases reduced within 30 min. and the pressure required to reduce was about 61 mmHg to 100 mmHg in 73.9% of cases.
