Congenital cystic adenomatoid malformation (CCAM) of the lung is a rare pulmonary malformation, associated with local aberrations of parenchymal tissue development, which have been classified lung bud anomalies. Lung bud anomalies include infantile lobar emphysema, congenital cyst of the lung, congenital cystic adenomatoid malformation, pulmonary sequestration and bronchogenic cyst. CCAM can enlarge rapidly by ball-valve air entrapment by cysts, lead to mediastinal shift and compression of the heart. compression of opposite lung may result in pulmonary hypoplasia and CCAM causes acute respiratory distress in newborn. We report a neonate with CCAM who were successfuly managed during perioperative period.

Recently, surmountable amounts of genes are being cloned without information about them and it has become neccessary to develop new techniques for discovering genes with more informaiion like as chromosomal location and possible functions. We have developed one such a method and applied it to search for genes that may be related with the neural development. The mRNAs were extracted from cerebral cortex of 18 week old human fetus, cDNAs were made by reverse transcription from these mRNAs and Uni-amp cDNAs having Uni-amp adapters at both ends were made for subsequent PCR. To observe the distribution of the Uni-amp cDNAs on the chromosome, fluorescent in situ hybridization was performed with biotin labeled Uni-amp cDNAs. Among the chromosome bands showing strong hybridization with the cDNAs, 7q22 was microdissected from the chromosome hybridized with unlabeled Uni-amp cDNAs and amplified by PCR with Uni-amp primers. These amplified cDNA fragment were subcloned to vectors and the nucleic acid sequences were analysed. As a result, 46 different clones were obtained. They were categorized as 12 clones of well characterized genes, 14 clones showing low homology with known genes, 13 clones of simply registered uncharacterized human cDNAs, 7 clones of unknown genes. In situ hybridization histochemistry of 34 novel genes, except 12 known genes, were performed on developing and adult rat tissue sections to see the tissue specificity and developmental expression of these genes. The expression of several novel genes were restricted to the nervous system. From these results, it may be suggested that our technique is very useful to clone the genes expressed in the developing human braine with confirmed chromosomal location. In addition, this cloning technique can be used to discover the new genes related with neural development in combination with functional screening methods.

OBJECTIVE: This study evaluated the complaint rates of musculoskeletal symptoms and investigated the related factors of musculoskeletal symptoms in the caddies. METHODS: For 316 caddies working at 6 regular golf courses, we used the self-recording questionnaires to examine general characteristics, job stress factors, subjective musculoskeletal symptoms designed by NIOSH, working environments, and working contents. RESULTS: The complaint rates of musculoskeletal symptoms according to the musculoskeletal criteria of NIOSH were 41.8% in the leg/knee/ankle/foot, 35.8% in the shoulder, 35.8% in the upper back/lower back, 28.8% in the neck, and 28.5% in the arm/wrist/fingers. Important factors affecting musculoskeletal symptoms were daily working hours during the high-demand season in all anatomical sites except the arm/wrist/fingers. Other related factors were degrees of winding and inclined in the golf courses, violent language and violence of customers, inability to regulate the velocity and work load control, heavy physical burden, instability of employment, and possibility of unemployment according to the specialty of caddies. As a results of multivariate logistic regression analysis, musculoskeletal symptoms of the neck, shoulders, back/lower back and leg/knee/ankle/foot were significantly influenced by working time over 12 hours in the high-demand season, and symptoms of the arm/wrist/fingers by low decision latitude (P<0.05). CONCLUSIONS: The complaint rates of musculoskeletal symptoms in the caddies were affected by working time over 12 hours and low decision latitude against excessively high psychological job demand.

Of 127 consecutive cases of relatively fresh rhegmatogenous retinal detachment, posterior vitreous detachments and their relation to type of retinal perforation were studied using a contact lens or Hruby lens and a biomicroscope for stereoscopic examination of the vitreous cavity and the fundus of the eve. Analysing 127 cases, the authors found a complets posterior vitreous detachment with collapse in 58 cases and a simple total pcsterior vitreous detachment in 69 cases. And posterior vitreous detachment was an indispensable factor for rhegmatogenous retinal detachment. The topographical site of election, however, varies with the type of perforation. Arrow-head tears occur preferentially in the upper half of the retina, particulaly with a predilection for the equatorial zone. Amog 26 horse-shoe shaped tears, 25tears were found in the upper half of the fundus and only one in the lower half. The horse-shoe shaped tears were always accompanied with total posterior vitreous detachment with collapse. In the series of 127 rhegmatogenous retinal detachment, 100 round holes were detected; 48 holes were found in the eyes wth total posterior vitreous detachment with collapse and 52 holes in the eye with simple total posterior vitreous detachment. The distribution of these perforations in the retina is of interest. The teares distributed almost equally in all quadrants. The vast majority occurred in the peripheral retina at equator or anterior to the equator and holes at juxtapapillary and intermedial areas are extremly rare. The authorse are of the opinion, that total posterior vitreous detachment with collapse, is one of the predisposing factors to lead to a horse-shoe shaped tear. In this type of vitreous detachment, the solid vitreous in the upper part is found only antereioly next to the vitreous base. In event of trauma and sudden movement of the eyeball, vitreoretinal adhesion, which located in the upper part of peripheral fundus may be pulled anteriorly and tangentially from the internal surface of the retina and so the base of the operculum deflects toward the ora serrata. The ascension phenomenon of the solid vitreous may also lead tc the formation of retinal tears in th elower part of the fundus. The convexity of the tear is always turned toward the optic nerve, and the concavity face the ora. The appearance of these rents may suggest that they not only are formed by a tearing process of a forward direction due to adhesion of the retina to the vitreous but also depend upon the typical network of retinal fibers. On the other hand, in simple total posterior vitreous detachment, a round hole of en occurrs in the equator as well as in macular, juxta papillary and intermedial region, because the solidification power of the formed vitreous operates as a force on the vitreoretinal adhesion toward the center of the eyeball.

A choroid detachment occurs most commonly after surgical operation for cataract, glaucoma, and retinal detachment. It is fairly characteristic for postoperative choroidal edema to be accompanied by hypotonia and a shallow anterior chamber. We have recently experienced 3 cases of choroid detachment after cataract operation, and acase of choroid detachment combined with retinal detachment after trabeculectomy. They were also accompanied by hypotonia and shallow anterior chamber, but had not would leakage. Among 4 cases, a case of choroid detachment was performed suprachoroidal tapping, the remaining were treated with prednisolone, cycloplegics, and pressure dressing. They were not of consequence and subsided without being noticed. A brief review of relating literatures was described.

BACKGROUND:Acute vestibular neuronitis is the disease of which the etiology and pathophysiology are largely unknown . But the viral infection and ischemia of the labyrinth and the vestibular nerve are considered as general etiology. This study was performed to support the viral infection rather than the ischemic theory. MATERIALS & METHODS:We studied seventy years old female patient who showed painful vesicles on left auricle and vertigo with spontaneous nystagmus to the right side. We performed physical examination, serologic test, ENG test, pure tone audiogram, brain magnetic resonance imaging and polymerase chain reaction. RESULTS:We found small vesicles and vascular injection in left EAC, herpes zoster IgG positive, spontaneous right beating in electronystagmograpy, 54% left canal paresis in Caloric test , decreasing left side Tc in velocity step rotatory test, decresed gain, deviation to left in symmetry and phase lead in sinusoidal harmonic acceleration test, normal range hearing in pure tone audiogram, microangiopathy on cortex in brain MRI and negative PCR. CONCLUSION:This case supports viral infection etiology rather than ischemia in vestibular neuritis. But more studies to find the etiology of vestibular neuronitis are required.

In this study, 55 patients (104 eyes) were studied in order to assess tear drainage, using a computer assisted gamma camera. Twentynine eyes had DCR, 29 eyes had CDCR with Jones' tube, and remaining 46 eyes were considered controls. We measured T1/2 values, the time in which a given amount of tracer drops to half in the conjunctival sac area. The time values were classified into 4 groups; Group I (3 min or less), Group II (3-6min), Group III (6-9min) and Group IV (9min or longer). In the patients with DCR and CDCR, tear drainage was faster than in the control group. Age was considered as a factor of delayed tear flow in those patients with DCR and controls, however, it was not a relevant factor in those patients with CDCR using Jones' tube.

E-cadherin is a calcium-dependent epithelial adhesion molecule which plays a role in the initial step of invasion of cancer cells. The step that follows the migration of separated tumor cells is a proteolytic lysis of basement membrane and extracellular matrix by protease of epithelial and endothelial cells such as matrix metalloproteinase (MMP). Vascular endothelial growth factor (VEGF) is known to be an endothelial cell-specific powerful mitogen as well as a vascular permeability factor. This study is aimed to evaluate the correlation between expression of these factors and pathologic or clinical variables and the roles and prognostic significance of those factors in squmous cell carcinoma and adenocarcinoma of the lung. Immunohistochemical stains were performed for E-cadherin, MMP-2, and VEGF in surgically resected specimens from 90 patients with squmous cell carcinoma and adenocarcinoma of the lung. Mean age of the patients was 59.7 years. Histologic type was categorized into 56 cases of squamous cell carcinoma and 34 cases of adenocarcinoma. Mean survival period of the 35 patients was 54 months. The immunohistochemical stains for E-cadherin, MMP-2, and VEGF revealed positive reaction in 67 cases (74.4%), 43 cases (47.8%), and 34 cases (37.8%), respectively. The expression of E-cadherin was higher in adenocarcinoma (82.4%) than in squamous cell carcinoma (69.6%). MMP-2 was expressed in the tumor cells, especially those invading into the surrounding stroma. The expression of MMP-2 was significantly correlated with the survival rate (p<0.05). The expression of VEGF in the tumor cells was significantly higher in cases with lymph node metastasis (p<0.05). In conclusion, these findings suggest that the expression of MMP-2 and VEGF predict poor prognosis of patients with squmous cell carcinoma and adenocarcinoma of the lung and that VEGF may play a role in tumor metastasis.
