To investigate incidence of acute gastroenteritis (AGE) caused by Yersinia enterocolitica and Y. pseudotuberculosis (referred to as Y. enterocolitica-pseudotuberculosis complex) in children, seropositive rates to major 8 serotypes of Y. enterocolitica-pseudotuberculosis complex antigens among 467 sera of three groups of subjects (298 acute gastroenteritis; AGE, 108 miscellaneous pediatric diseases; MPD, and 61 healthy medical students; HMS) were investigated by bacterial agglutination test using standardized, heat-killed, phenolized, smooth 0 antigens. In addition, cross-reactions between yersinia agglutinins and Widal agglutinins in patients with AGE caused by Y. enterocolitica-pseudotuberculosis complex were examined in paired serum specimens. Seropositive rates to Y. enterocolitica-pseudotuberculosis complex among three groups, AGE, MPD, and HMS, were 36.5%, 13.8%, and 14.7%, respectively. Of 109 seropositive AGE patients, the most common type-specific agglutinin which showed predominating agglutinin titer to one of 8 serotypes of Y. enterocolitica-pseudotuberculosis complex antigens was PO4b (27.5%), followed by PO2a (23.8%), EO3 (16.5%), PO5a (13.7%), PO5b (9.1%), PO3 (4.5%), EO9 (2.7%), and POlb (1.8%), in orders. The Widal agglutinins cross-reacted to Y. pseudotuberculosis PO4b antigen, but the yersinia agglutinins were differentiated from Widal agglutinins by rising agglutinin titers in paired serum specimens taken one to three weeks apart. In conclusion, acute gastroenteritis caused by Y. pseudotuberculosis in children must be regarded as a fairly common enteric disease in children.

Since the reservior of leptospires organism is consisted of a broad spectrum of animals, the best method of prevention is vaccination. The clinical trial of leptospires vaccine conducted on human volunteer for its immunogenicity and safety. Summarized results are as follows: 1. The Oral temperature among vaccinated group ranged from 36.7 +/- 0.34 degrees C, while in placebo injected group it ranged from 36.4 +/- 0.46 degrees C to 36.7 +/- 0.53 degrees C. There wan no association between vaccination and fever (p<0.05). 2. Mild local reactions revealed in vacciness were swelling (50-75%), Redness(75-90%), and induration(25-40%). Placebo injected group revealed only redness in 12.5% in the 1st injection and 37.5% in the second injection. The duration local reactions on injection site for both vaccinees and placebo groups disappeared within 48 hours. 3. Generalized Symptoms complained by the vaccinees were myalgia (25%), back pain(15%), headache(15%), pruritus(15%), and abdominal pain(10%), whereas placebo group complained of headache(25%), myalgia(12.5%), back pain(12.5%), pain in eyes(12.5%), abdominal pain(12.5%) prutitus(12.5%) and nausea(12.5%). 4. The serological test(MAT) of vaccinees showed geometric mean antibody titer as follows: a. L. icterohemorrhagiae lai, 1 week after 1st vaccination: 22.45, 1 week after 2nd vaccination: 111.23, 3 week after 2nd vaccination: 266.64, b. L. canicola canicola, 1 week after 1st vaccination: 24.62, 1 week after 2nd vaccination: 123.92, 3 week after 2nd vaccination: 276.55, c. L. icterohemorrhagiae copenhageni, 1 week after 1st vaccination: 28.28, 1 week after 2nd vaccination: 128.55, 3 week after 2nd vaccinaton: 247.88, Whereas all of the placebo injected group, showed below 1 : 20 titers. The sero-conversion rate of vaccinees were 100 percent.

In the unusual manifestation of right upper lobe collapse confusing with mediastinal or parenchymal mass, both alteration of the pulmonary vessels and shifting pattern of the collapsed lobe to the periphery on supine positionare the key to the diagnosis of it rather than mediastinal or parenchymal mass. The mechanisms of these unusual manifestation s are obscure, however lobar torsion and gravity factor are considered to be a main process. Authors have experienced 2 cases of unusual manifestations of right upper lobe collapse due to bronchogenic carcinomaduring resent 2 years in Kyung Hee University hospital, and prsent radiologic findings.

The limitation so direct or indirect laryngoscopy and laryngogram in detemining the exact site and anatomiclocation of laryngeal carcinoma were well documented by many authors. As compared with laryngoscopy and laryngogram, CT study for laryngeal cancer is more exact and accurate method demonstrating anatomic sites of involvement, invasion into deep soft tissue spaces of endolarynx, destruction of laryngeal cartilages and cervical metastasis. Fourteen laryngeal cancer patients proven by laryngoscopic biopsy were further examined by computed tomography for staging. The authors compared laryngoscopic findings with those of computed tomography, and their clinical, surgical and computed tomographic findings were analysed. The results were as follows; 1. All patients were proved as squamous cell carcinoma. They were 12 males and 2 females aged over 50 yrs. 2. Common clinical symptoms were hoarseness, dysphagia and swallowing difficulty. The pirmary anatomic sites determined by CT were 8 transglottic, 2 glottic, 2 supraglottic and 1 pyriform sinus respectively. They were 2 T1. 7 T2, 1 T3, 3 T4 by TNM systems, respectivly. (One case was difficult to evaluate exactly). 3. Invasion into deep soft tissue spaces of endolarynx, cartilage destruction, and neck metastasis were relatively predominant in transglottic caracinomas. 4.CT was superior in evaluating tumor invasion, especially into deep soft tissue spaces of endolarynx, laryngeal cartilages and metastasis ot soft tissue and lymph nodes of neck. However CT had some limitation in determining primary site of laryngeal cancer.
