Korean Journal of Gastrointestinal Endoscopy 1992;12(2):227-230
The clinical review was done on 17 cases with the foreign body in the upper gastrointestinal tract who underwent endoscopic removal of foreign body at Kang Nam Sacred Heart Hospital from Dec. 1981 to Dec. 1991. The results were as follows: 1) The age distribution varies from 3 months to 72 years of age, being most prevalent under 5 years of age. 2) The incidence of foreign body in the order of frequency was coin, fish bone, safety pinring, peanut, keyring, food bolus, artificial teeth and medal. Among 17 cases, 9 cases(53.0%) were lodged in the esophagus and 8 cases(47.0%) were lodged in the stomach. 3) Dysphagia or globus was the common symptom in 8 cases(47.2%), followed by absence of symptom in 7 cases(41.2%), upper abdominal discomfort in 1 case(5.8%) and vomiting in 1 case (5.8%). 4) l0 cases(58.8%) of foreign body were removed within 72 hours and 7 cases(41.2%) of foreign body were removed after 72 hours.

2.Congenital Pulmonary Lymphangiectasis.
Korean Journal of Legal Medicine 1999;23(1):82-87
Congenital pulmonary lymphangiectasis is a rare cause of severe respiratory distress in the newborn period and most of these patient die, usually within the first 24 hours of life. The light microscopic characteristics of the lungs are a network of partly tubular, partly cystically enlarged lymph vessels within large areas of connective tissue and they have thin wall lined by endothelium. Also congenital pulmonary lymphangiectasis is closely associated with cardiovascular malformation, and most frequently occurs in the clinical setting of congenital heart disease with or without pulmonary venous obstruction(total anomalous venous return, atresia of large pulmonary veins) The authors describe three typical cases of congenital pulmonary lymphangiectasis.

A 56-year-old woman presenting a 10-year history of atrophic discoid patches with underlying subcutaneous nodules was seen. These skin lesions were distributed on the upper arms bilaterally. Biopsy specimens taken from the lesional skin showed epidermal and dermal changes consistent with the discoid lesions of the cutaneous lupus erythematosus. Deep dermis and subcutaneous fat tissue revealed sclerosis and fibrinoid alterations of the collagen and necrosis of fat cells, the features corresponding to the lupus ei ythematosus profundus. She had no laboratory evidences suspective of systemic lupus erythematosus or other connective tissue diseases. This patient with lupus erythernatosus profundus which cleveloped subsequent to the discoid lesion is consiclered to be a rarely encounteririg observation in lupus erythematosus.

Reticulated pigrnented anomalies of the flexures is a pigmentary disorder bearing genetic back ground, also known as Dowling Degos disease or dark dot disease. It is characterized reticulated brownish black macules on the flexural areas with the histological features of filiform pigmented epidermal downward proliferation and the presence of intraepidermal keratin containing cysts. We report 34-year-old housewife who showed brawnish black reticulated macules on her axillae, anterior neck and genitocural folds. Pigmented comedones were also found at the marginal areas of the axillae. Biopsy specimen revealed the presence of intraepidermal keratin containing cysts and basilar hyperpigmentation.

The tricuspid valve is not a simple but a complex structure, tricuspid valve complex. This complex is composed of tricuspid orifice, annulus, valve leaflet, chordae tendineae and papillary muscles. There are flew articles about these structures. The authors studied tricuspid valve complex in 53 cases of normal korean adults, such as circumference of tricuspid annulus, the maximum diameter of the tricuspid orifice, height and breadth of the cusps, including commissures, the ratio of rough to clear zone, the number of scallops of posterior cusp, the number, length and pattern of arrangement of the several types of chordae, the number and morphological characteristics of papillary muscles.

Majocchi's disease is one of chronic vascular disorders of the skin, histologically showing capillaritis with lymphoid cell infiltration. Although the hypothesis of delayed type hypersensitivity reaction against foreign antigen is proposed as the mechanism producing this condition, there are much yet to be defined. We tried to examine the lesional skin of five patients with Majocchi's disease by the direct immunofluorescence with anti-human immunoglobulins, C 3, and fibrin. As a result we found the deposition of immunoglobulins (M, and G) in papillary blood vessels in four patients, and C 3 and fibrin were found in all five patients. C3 was also found at the dermoepidermal junction in three patients. These findings suggest the posssibility that antibody mediated immunologic processes may alsobe involved in the pathogenesis of this disorder. With this observation Majocchis disease could be considered as a chronic immune vasculitis.

8.The recent trend and determinants of service diversification in Korean hospitals.

Service diversification is recognized as an important strategy against turbulent environmental change. This study is designed to find out the trend of service diversification in Korean health care organizations and also to identify factors associated with the degree of service diversification. Data were collected from 69 hospitals out of 71 hospitals with over 300 beds. Important findings are summarized below. 1. Types of diversification are closely related to hospital size. Large hospitals have a tendency to provide sophisticated service requiring specialized skills and equipment, while small hospital have concentrated their efforts on health screening programs. 2. The more competitive and bigger hospitals are, the greater number of services that provide. Also, hospitals operating rational management information systems provide more services. Contrary to the expectation, hospitals with a low performance during last 3 years showed more service diversification. 3. A trend of more diversification was observed in hospitals whose chief executive officer used a prospector strategy. 4. A multiple regression analysis revealed that bed size, competitive environment, degree of rational management, and the growth pattern were significantly associated with teh service diversification.

BACKGROUND: Adenosine 5'-tetraphosphate(ATPP), an endogenous nucleotide, is stored in cells and released into the extracellular space upon stimulation. Some of the biological responses to ATPP were reported, but characteristics of its receptor were not well known. Present study was conducted to investigate the effects of ATPP on mechanical contractility, resting membrane potential and action potential of rat left atrium. METHODS: Left atrium was isolated from Sprague-Dawley rat. Mechanical contraction induced by electrical field stimulation(EFS) was recorded on polygraph using force transducer. With glass microelectrodes(10 MOmega), potential difference across the membrane was measured and recorded on an oscilloscope and a polygraph. RESULTS: ATPP reduced the left atrial contractility with concentration-dependent manner. ATPP also hyperpolarized the resting membrane potential and decreased the action potential duration of the left atrial cell. Nucleotides other than ATPP, such as ATP, ADP, AMP and adenosine, have the same effect as ATPP. However, there is no difference among the nucleotides. Prior treatment of DPCPX, a P1-purinoceptor blocker, inhibited the ATPP-induced negative inotropism and changes of the membrane potential. But suramin, a nonselective P2-purinoceptor blocker, did not alter the effects of ATPP. alpha, beta methylene ADP and adenosine deaminase, which attenuates hydrolysis of adenine nucleotides and inactivates adenosine respectively, did not influence the effects of adenine nucleotides except for adenosine. CONCLUSION: ATPP reduced the mechanical contractility, hyperpolarized the resting membrance potential and decreased duration of action potential of rat left atrium. These effects were induced by ATPP directly, not by adenosine from hydrolyzed ATPP.

A case of benign lichenoid keratosis(BLK) developed in a 25-year-old female is presented. She had two erythematous plaques with slightly verrucous surfaces on the lips for 4 weeks. A biopsy specirnen taken from the periphery of the lesion revealed a focal parakeratosis, the absence of granular cells, and hydropic degeneration of the basal cells in the epidermis. The upper dermal infiltrate composed chiefly of lymphacytes intermingled with a few histiocytes was also seen. The direct immunofluorescent study showed depositions of a few cytoid bodies and fibrin around the areas of the dermoepidermal junction. These plaques on her lips, demonstrating lichenoid tissue changes, cleared in 8 weeks from the evalution, without any treatment.
