Lymphomatoid papulosis is a strange disease; clinically benign, histologically malignant. Clinically, it may simulate pityriasis lichenoides et varioliformis acuta. The diagnosis is based on the typical histopathological features suggestive of malignant lymphoma, due to the presence of polymorphous lymphoid infiltrate consisting of small lymphocytes intermingled with conspicuous large atypical cells. We experienced a case of lymphomastoid papulosis in 35-year-old woman. Initially, her skin lesions developed as erythematous papules on the extremities, gradually spreading centrifugally with a tendency to involute slowly without treatment, leaving brown wrinkled surface and shallow ulceration. These skin lesions tended to become worse in warm weather and better in cold weather. At first visit, multiple erythematous grouped, ulcerated papules and nodules are seen. 18 months after first visit, most skin lesions are regressed except 5 erythematous pinhead sized papules on right leg in spite of no treatrnent. Labcratory examiniations of CBC, VDRL, urinatlysis, blood chemistry and chest X-ray were all within normal limits. Histopathologically there were hygerkeratosis, mild acanthosis, exocytosis in epidermis, and numerous lymphoid cells were infiltrated especially on perivascular and periappendegeal area, and many atypical cells showing hyperchromatic nuclei, kidney-shaped nuclei and mitotic figures in dermis.

Pneumocystis carinii is a pulmonary pathogen of immunocompromised humans or other mammals. Its infection results from activation of organisms involved in latent infection or from new infection through the air. Almost all children are known to be infected within 2 to 4 years of birth, though prenatal transplacental transmission has not yet been demonstrated. In this study we observed experimental P. carinii infection in neonatal rats, thus investigating the possibility of transplacental vertical transmission by Diff-Quik staining of the lung impression smears and in-situ hybridization for lung sections. The positive rate of P. carinii infection in immunosuppressed maternal rats was 100%, but that in normal maternal rats was 0%. Cystic forms of P. carinii were observed in three of six 1-week old neonatal rats born of heavily infected mothers, but none of them was positive by in-situ hybridization. Five weeks after birth, cystic forms were detected in four neonatal rats. In the lobes of the lungs, no predilection site of P. carinii was recognized. Counts of cystic forms on smears and the reactivity of in-situ hybridization in the lungs of neonatal rats were significantly lower than in maternal rats. The present findings suggest that P. carinii is rarely transmitted through the placenta and proliferates less successfully in the lungs of neonatal rats than in mothers.

The characteristics of modern society's trauma is a propensity for multiple and severe trauma, specially, the fatal damage accompanied by facial bone fracture. We observed the malocclusion owing to delayed prompt treatment If the fractured fragments is crushed severely, it is difficult to make them positioned into the normal anatomical states and to fix them tightly. Post-traumatic malocclusion is usually caused by a delay in treatment and inadequate anatomic reduction. Inadequately treated facial bone fractures result in facial disfiguring and functional impairment of mastication and speech.We performed 27 cases of correction of post-traumatic malocclusion between April 1994 and June 1996. We used various operative techniques such as anterior segmental osteotomy, Le Fort osteotomy, maxillary segmental osteotomy and mandibular sagittal split osteotomy. If the malocclusion was due to disarrangement segmental osteotomy. If that malocclusion was attributed to a malpositioned skeletal bone, we take maxillary segmental osteotomy or mandibular sagittal split osteotomy. We acquired the desirable occlusion first followed by a fixation between the mandible and maxillary skeletal bones with the bite block. The aim in the correction of malocclusion was to create a harmony of centric relation and centric occlusion. After operation, intermaxillary fixation with bite block have many advantages in the treatment of malocclusion.

The inverted nipple presents many problems including both cosmetic and functional aspects and impairment in breast feeding. the histopathologic characters of inverted nipple are that inverted nipple has less fibromuscular tissue than normal nipple and has short lactiferous duct and dense fibrous tissue. Many surgical and non-surgical techniques have been designed for correction of the inverted nipple. But most of these techniques have produced unsatisfactory problems. especially undesirable recurrence is most important problem. We experienced 19 inverted nipples in 12 patients between March 1995 and January 1998. We combined modified Teimourian method, purse-string suture and Z-plasty. and had good result for 3weeks to 30months follow up. This method was effective for correction of the inverted nipple with low recurrence rate and simple techniques.

Livedo vasculitis or vasculitis of atrophie blanche is a clinical entity which can be distinguished from cutaneous vasculitis by distinctive pathology and immunopathologic study. A 18-year-old female with erythematous, telangiectatic, purpuric or hyperpigmented patches, intermingled with white atrophic ivory patches on her legs of 3 years duration was seen in June 3, 1982. The histologic examination of an atrophic patch showed proliferation and occlusion of blood vessels in the upper dermis with patchy atrophy of the epidermis. The immunopatbologic features of an atrophic patch revealed deposits of IgM, Ca and fibrin as a definitive immunofluorescence vessel pattern. This suggests that the livedo va.sculitis or vasculitis of atrophie blanche may he considered one of the immune vasculitides. This patient had received aspirin and persantine for 4 months, and moderate therapeutic effects could be noticed.

8.Usefulness of Renal Computerized Tomography in Acute Pyelonephritis.
Korean Journal of Nephrology 1999;18(1):96-104
We carried out a prospective study with three aims:(1) to observe the renal computed tomography (CT) patterns in APN; (2) to compare the radiological imaging techniques used for the diagnosis of APN(renal CT and DMSA scintigraphy); (3) to correlate the clinical manifestations with CT findings in APN. Between 1 April 1997 and 31 March 1998, all adults who were admitted to our internal medicine ward with APN were included in this study. They presented with symptoms and signs of upper UTI, accompanied by pyuria and bacteriuria. All patients with renal abscess, or uropathy on the ultrasound (US) examination, were excluded from the study. 23 cases of APN were evaluated. There were 22 females and 1 male. The mean age of 23 cases was 45+/-19 years old(from 20 to 79 years old). Two cases we re diabetics. On the basis of postcontrast- enhanced CT findings, 23 cases were grouped into (1) Group I(6 cases), no abnormal lesions; (2) Group II(13 cases), wedge-shaped lesions (focal or diffuse); (3) Group III(2 cases), focal mass-like lesions; and (4) Group IV(2 cases), diffuse mass-like lesions. The incidences of CT and DMSA scintigraphy abnormalities were 74%(17/23) and 68%(13/19), respectively. A significant correlation was demonstrated between the clinical parameters(including duration of flank pain and fever, ESR, serum creatinine, and degree of pyuria) and the pattern of renal parenchymal findings detected on CT(P<0.05). In conclusion, we classify APN into four subgroups according to CT findings, and suggest that renal CT is useful in the diagnosis and assessment of severity of APN.

In the course of immunoscreening of Clonorchis sinensis cDNA library, a cDNA CsRP12 containing a tandem repeat was isolated. The cDNA CsRP12 encodes two putative peptides of open reading frames (ORFs) 1 and 2 (CsRP12-1 and -2). The repetitive region is composed of 15 repeats of 10 amino acids. Of the two putative peptides, CsRP12-1 was proline-rich and found to have homologues in several organisms. Recombinant proteins of the putative peptides were bacterially produced and purified by an affinity chromatography. Recombinant CsRP12-1 protein was recognized by sera of clonorchiasis patients and experimental rabbits, but recombinant CsRP12-2 was not. One of the putative peptide, CsRP12-1, is designated CsPRA, proline-rich antigen of C. sinensis. Both the C-termini of CsRP12-1 and -2 were bacterially produced and analysed to show no antigenicity. Recombinant CsPRA protein showed high sensitivity and specificity. In experimental rabbits, IgG antibodies to CsPRA was produced between 4 and 8 weeks after the infection and decreased thereafter over one year. These results indicate that CsPRA is equivalent to a natural protein and a useful antigenic protein for serodiagnosis of human clonorchiasis.

Acute necrotizing encephalopathy is a recently established disease entity, proposed by Mizuguchi et al in 1995, that shows a characteristic symmetric and multifocal involvement of both thalamus, brainstem tegmentum, cerebral periventricular white matter, and cerebellar medulla. It is known to be prevalent in Japan and other Far Ease countries. The etiology of the acute necrotizing encephalopathy remains unknown. The typical course of acute necrotizing encephalopathy is the development of the irreversible neurologic symptoms related to brain lesions. The diagnosis can be made on the basis of the combination of a typical clinical profile and characteristic radiologic findings. We experienced a first case of acute necrotizing encephalopathy in a 9 month old boy in Korea. We report this case with the brief review of related literatures.
