Chest CT scans of 70 patents with malignant lymphoma were reviewed to evaluate the thoacic manifestation of malignant lymphoma. Sixteen patients had Hodgkin's disease and 54 patients had non-Hodgkin's lymphoma. The thoracic involvement of malignant lymphoma was observed i 47 patients (67.1%) and 11 of these patients had Hodgkin's disease, and 36 had non-Hodgkin's lympoma. The most common finding was mediastinal lymphadenopathy and the most frequently involved sites were anterior mediastinal and paratracheal lymph nodes. Pulmonary parenchymal involvement was seen in 11 patients (15.7%), and CT scan showed thickening of bronchovascular bundle, parenchymal consolidation and nodules. Pleural effusion was seen in 18 patients (25.7%), however, without any evidence of parietal pleural thickening in all cases. Involvement of chest wall and breast was seen in two patient(2.9%). The data obtained through the current study showed no differences from those of previous reports, except the fact that there was no CT evidence of pleural thickening in patients who had pleural effusion.

In order to know the species and frequency of human parasitic infection diagnosed by biopsy, 149 cases (0.18%) of parasitic infection were reviwed, which were selected from 80,947 biopsied materials submitted for routine histopathological examination during a period of 10 years from 1980 to 1989 at Department of Pathology, Chonnam National University Hospital. They consisted of 112 cases of cysticercosis, 17 paragonimiasis, 7 clonorchiasis, 4 amebiasis, 1 sparganosis, 1 enterbiasis, 1 aniskiasis, and 1 fascioliasis respectively. Based on morphological preservation of cysticercus, they could be divided into mild (20.2%), morderate (40.4%), and severe (39.4%) degeneration. Except 2 cases biopsied at the lungs, 15 cases of ectopic paragonimiasis were located at abdominal cavity (8 cases) and central nervous system (7 cases). One case of intrahepatic fascioliasis was observed. This is the 13th human fascioliasis reported in Korea. From the above results, the frequency of parasitic infections found in biopsied specimens was on the decrease as the cysticercosis and ectopic paragonimiasis.

Most of the peripheral nerve injuries from crushing or compressive forces are accompanied by surrounding soft tissue injuries. As a result, poor vascularity due to fibrosis and sacr formation compromises regeneration of the grafted nerve. Vascularized nerve graft shows superior regeneration to that of a non-vascularized one. However, the human body provides few donor sites of vascularized nerve graft clinically. We presumed that the prefabricated myoneural or adiponeural flap, which include fabricated nerves wrapped with surrounding vascularized muscle or adipose tissue flap, influences superiorly on the regeneration of grafted nerve because that surrounding vasculatity indirectly enhances the vascularity of the grafted nerve itself. Thirty adult male Sprague-Dawley rats were divided into three groups: 1) conventional reversed autogenous graft of the femoral nerve alone(n=10); 2) nerve graft entubulated with abdominal adipose tissue flap with a pedicle of inferior epigastric artery(n=10); 3) nerve graft entubulated with adductor muscle flap with a pedicle of the first muscular branch of the femoral artery(n=10). At three months postoperatively, grafted nerves were examined by electrophysiologic study to check amplitudes and motor nerve conduction velocities, as well as histopathologic study for evaluation of regenerated nerve cells, fibrosis and neo-vascularization. Consquently, nerve regeneration was found in all three groups. Both the myoneural and adiponeural flap groups had better improved results of nerve regeneration compared to that of the conventional nerve graft group. The result of myoneural flap group was superior to that of the adiponeural flap group. The myoneural flap group showed minimal fibrosis and less prominent neovascularization around moderately regenerated nerves. The adiponeural flap group showed more severe perineural and endoneural fibrosis, as well as vascular proliferation around focal regenerated nerves. The results of myoneural flap group proved to be statistically significant. We concluded that it is possible to use nerve graft entubulated with a vascularized muscle flap (myoneural flap) as a substitute for vascularized nerve graft.

To evaluate the diagnostic accuracy of two-dimensional echocardiogrphy(2-D echo) in ventricular septal defect, location and size of the defects, estimated right ventricular systolic pressure and associated cardiac anomaly were compared to the operative findings in 139 children operated for correction of ventricular septal defect at Severance Hospital from Jan. 1983 to June 1987. In addition, postoperative complications and mortality cases were anlysed. The following results were obtained; 1) Perimembranous defects were 82 cases(66.1%), subarterial infundibular defects 33 cases(26.6%), and muscular defect was found in only 1 case(0.8%). The accuracy of 2-D echo in localizing the defects was 84.2%. 2) In 79.2% of the patients, the defects were moderate to large in size, and actual size measured at operation was larger than that obtained by echocardography in general. 3) The estimated right ventricular systolic pressure was correlated(r=0.650) with that measured at the operating field. 4) Combined cardiac anomalies were patent ductus arteriosus(22 cases), atrial septal defect(3 cases), valvular pulmonic stenosis(2 cases) and interventricular septal aneurysm(2 cases). The sensitivity of 2-D echo in detecting these anomalies was 65.5% and the specificity was 96.4%. 5) Among 32 patients who had postoperative complications, in two thirds, there were pulmonary complication including lung atelectasis(16 cases), pleural effusion(5 cases)and pneumonia(5 cases). 6) Operative mortality was 2.9%(4 cases). The causes of death were low cardiac output state due to left ventricular myocardial failure in 3 patients and respiratory failure from asphyxia in one case. In conclusion, with close cooperation with cardiac surgeons, there will be few problems in diagnosing and operating patients with ventricular septal defect on the basis of two-dimensional echocardiographic findings without invasive procedures, such as cardiac catheterization, even with pulmonary hypertension, unless Eisenmenger syndrome is complicated.

A 4-year-old girl developed acute motor, sensory impairment, lower abdominal pain and urinary dysfunction after URI. In acute stage of disease, MRI showed diffuse spinal cord swelling and high signal intensity on T2WI below T2 body level. The patient did not improved and one month later, follow-up MRI showed diffuse spinal cord atrophy and syrinx formation as sequelae of ATM on T1WI below T9 level. To our knowledge, this is the first case showing the sequelae of acute transverse myelitis seen in Korea.

A case of contact dermatitis due to herb onintment is described in a 24 year-old female patient. After topical application of herb ointment, she developed erythematous papules and plaques on the face and neck. Patch test revealed positive reactions to ammoniated mercury, thimerosal, and the herb ointment. Energy-dispersive X-ray microanalysis of the herb ointment showed a striking peak for mercury.

Annular erythema associated with lupus erythematosus/ Sjogrens syndrome has recently been described in Orientals. We present a patient with recurrent annular erythema who partially demonstrated features of lupus erythematosus. A 32-year-old man was referred to us for recurrent annular erythema. Laboratory findings revealed mild leukopenia and the presence of antinuclear antibodies at a titer of 320 with a finely speckled pattern on Hep-2 substrates. Anti-Ro/La antibodies were also detected. A skin biopsy specimen revealed the findings of perivascular and periappendageal lymphocytic infiltration without prominent hydropic degeneration of the basal layer. Skin lesions subsided with hydroxychloroquine (400-200mg/day).
