Clinicalstudies on thirty patients with lichen planus seen during the past 9 years from 1968 to 1976 at the Department of Dermatology, Busan National University Hospital were ma,de;particularly, varied clinical types of the disease and significance of histological findings were emphasized. The results obtained were as follows; 1. The incidence of lichen planus was 0.17% patients to total number of dermatologic 2. There were 19 males and 11 females in this series. The age at the first visit varied from 16 years to 71 years, and the pitients between 21 and 50 years occupied 76.7% of all. 3. The most common site of the initial lesion was extremities(66.7%), and flexor surface was rather common than extensor surface. And lesions of trunk, oral mucosa, extemal genitalia were also noticed. 4. The most common clinical type was chronic localized type(11), and hypertrophic type(4), Iichen planus of mucous membrane(4), annular type(4), acute widesprearead type(3), vesicobulIous type(2), linear type(2), follicular type(l) were also noticed. 5. Pruritus developed in 22 patints(73.3%) an@d Koebners phenomenon was noticed only in R cases(10%). 6. Histopathological examination of 25 biopsy specimens showed epidermal changes of hyperkeratosis(24), acanthosis(22), hypergranulosis(21), elongation of rete ridge(8) and liquefaction degeneration of hasal cells(25). Dermal changes include bandlike infiltration of infIammatory cells(24), melanophages in upper dermis(18), colloid or eosinophilic body(9), and dermo-epidermal separation(3).

Atrophie blanche which was first described by Milian in 1929 is a sistinct entity and not a variation of stasis dermatitis. We reported a case of atrophie blanche which occurred in 21 year-old female. She had erythematous patches, telangiectaic purpuric areas, small 1 to 2mm ectasias suggestive of small angiomas with central ulcer, pustules and crusts on both lower legs and dorsa of feet without severe painful sensation. Histopathologic findings showed endothelial proliferation of the capillary blood vessele of dermis, presence of fibrinoid material on the superficial blood vessels and storma, and infarction of the epidermis and superficial corium. Response to treatment was not satisfactory with antibiotics and corticosteroid.

Intractable diarrhea associated with secondary amyloidosis in rheumatoid arthritis (RA) is a serious clinical entity with poor prognosis. We describe a 39-year-old male RA patient who presented with intractable diarrhea. Biopsy findings of terminal ileum and colon revealed amyloidosis secondary to RA. Effective treatment of rheumatoid arthritis resulted in remission of intractable diarrhea caused by amyloid protein deposition.

BACKGROUND: Recently, the commercial kits for measurement of the absolute number of CD34+ cells have been introduced as a standard method. The aims of this study was to investigated optimal timing of peripheral blood progenitor cell(PBPC) collection and optimal CD34+ cells dose transplanted by measurement of the absolute CD34+ cells. METHODS: We measured total leukocyte count, mononuclear cell count and the absolute number of CD34+ cells using ProCOUNT(Becton Dickinson, USA) in peripheral blood from 54 patients and 7 normal donors who underwent 101 leukapheresis for PBPC collection. We studied correlations among the absolute number of circulating CD34+ cells, other predictors and harvesting yields. We investigated relationships between the posttransplant hematopoietic recovery and CD34+ cells dose in 30 patients. RESULTS: The total number of CD34+ cells in harvesting products could be mostly predicted from the absolute number of circulating CD34+ cells. From 4 to 6 day after G-CSF mobilization, the absolute number of circulating CD34+ cells was peaked. A number of circulating CD34+ cells more than 20/microliter ensured 2.5x106 CD34+ cells/Kg in harvesting products. The patients received CD34+ cells dose >3.5x106/Kg led to a significantly faster recovery of platelets, compared with the patients receiving <3.5x106 CD34+ cells/Kg(P<0.05). CONCLUSIONS: These results suggest that PBPC collection should be started at day of circulating CD34+ cells more than 20/microliter or 4-6 days after G-CSF mobilization for successful leukapheresis and the CD34+ cell dose more than 3.5x106/Kg for PBPC transplantation could predicted rapid hematopoietic recovery.

Catastrophic antiphospholipid syndrome is a highly fatal condition characterized by widespread thromboembolism subsequent to a triggering factor (e.g., infection, trauma, and neoplasia) in antiphospholipid antibody-positive patients. This paper reports a case of a 29-year-old male without the underlying disease who developed extensive mesenteric thromboembolism and jejunal necrosis during the treatment for acute enteritis. The patient’s condition was improved with low-molecular-weight heparin and an intravenous Ig treatment with emergency surgery. The serum antiphospholipid (anticardiolipin IgM) and lupus anticoagulant antibody tests showed positive results. Acute infectious enterocolitis is generally considered a mild disease. On the other hand, aggressive evaluation and treatment should be considered if the clinical conditions do not improve and deteriorate rapidly despite appropriate antibiotic treatment because of the possibility of acute immunological complications, such as catastrophic antiphospholipid syndrome.

BACKGROUND: We reviewed the guidelines for the transfusion of red cells, platelets, and fresh frozen plasma (FFP) of the Korean Society of Blood Transfusion and modified the previous guidelines for transfusions at our hospital. We evaluated the appropriateness of the current hospital transfusions with these algorithms based on these guidelines. METHODS: The medical records of 266 transfusion episodes of patients receiving transfusions of red cells (144), platelets (61), and FFP (61), were reviewed retrospectively at Ewha Womans University Mokdong Hospital during 2002. RESULTS: Inappropriateness rates for transfusion episodes were 2.8% for red cells, 4.9% for platelets, and 44.3% for FFP. 144 red cell transfusions comprised 73 episodes (50.7%) in acute blood loss and 71 (49.3%) in chronic anemia. Among them, 2 episodes in each condition were assessed as inappropriate, respectively. 61 platelet transfusions comprised 32 episodes (52.5%) for a prophylaxis in marrow failure and 13 (21.3%) for active bleeding and 6 (9.8%) for acute disseminated intravascular coagulation (DIC) and 10 (16.4%) for others. Among them, 3 episodes for clinical bleeding were assessed as inappropriate. Out of 61 FFP transfusions, 34 episodes (56%) (16 liver disease with complications, 11 acute DIC, and 7 others) were assessed as appropriate and 27 episodes (44%) (8 liver diseases without complications, 10 surgical procedures and 9 others) were assessed as inappropriate. CONCLUSIONS: We modified our previous guidelines for transfusions according to the transfusion guidelines proposed by the Korean Society of Blood Transfusions. These guidelines could be easily applied to evaluate the appropriateness of transfusions performed at our hospital and to specify the cases of inappropriate transfusions.

Sclerosing peritonitis (SCP) is a syndrome of multiple causes that is characterized by the thickening of peritoneal membrane and subsequent ultrafiltration failure and intestinal obstruction. We report a case of sclerosing peritonitis initially suspected of tuberculous peritonitis in a patient with pulmonary tuberculosis. A 35-year-old man presented with recurrent exudative ascites of unknown origin. He had been switched from peritoneal dialysis to hemodialysis because of recurrent peritonitis 6 months ago. Laparoscopic peritoneal biopsy revealed excessive formation of capillaries and monocyte infiltration without evidence of tuberculosis. He was discharged without further treatment. Four months later, he was readmitted with intestinal obstruction. Exploratory laparotomy revealed that the whole small intestine was encased in a thick and fibrous peritoneal capsule. Pathologic examination of peritoneal membrane showed absence of mesothelium and extensive proliferation of fibroconnective tissue, which was compatible with sclerosing peritonitis.

BACKGROUND: Third-generation hydroxyethyl starch (HES) solutions have been developed to minimize negative effects on hemostasis. In normal pregnancy, the coagulation activity increases, reaching a maximum around term. This study examined the effects of hemodilution with HES 130/0.4 (6%) on blood coagulation in parturients in vivo and in vitro. METHODS: Forty parturients scheduled for cesarean sections were assigned randomly to receive either 500 or 1,000 ml of HES 130/0.4 (6%). Rotation thromboelastometry (ROTEM(R)) measurements were performed before and after administering HES 130/0.4 (6%). In addition, blood samples obtained from 20 randomly selected parturients were diluted 10% to 40% using HES 130/0.4 (6%), and ROTEM(R) measurements were performed before and after dilution. The changes from baseline and the effects of dilution were analyzed by ROTEM(R) parameters. RESULTS: Infusions of 500 or 1,000 ml of HES 130/0.4 (6%) in the parturients altered the clot formation time, alpha angle, and maximal clot firmness, although all remained within normal ranges. HES 130/0.4 (6%) affected in vitro blood coagulation in parturients' blood containing 10, 20, 30, and 40% HES. The clotting time was prolonged at each dilution percentage, but remained within the normal range. Other parameters showed an impairment of the coagulation system. CONCLUSIONS: Blood coagulation in parturients may be compromised at high dilution ratios of HES 130/0.4 (6%) to blood. Nevertheless, the infusion of 1,000 ml of HES 130/0.4 (6%) in normal parturients did not significantly affect blood coagulation.

BACKGROUND: Pringle maneuver and nitroglycerin (NTG) administration to reduce hemorrhage during hepatectomy may affect renal blood flow (RBF) and renal cortical perfusion (RCP) by reducing blood pressure (BP), perload and others. However, so far there have been no studies on RBF and RCP changes during and after hepatic vascular maneuver in hepatectomy. The purpose of this study was to evaluate the changes in RBF and RCP along with low dose (2 microgram/kg/min) NTG with or without low dose (3 microgram/kg/min) dopamine after the occlusion and reperfusion of hepatic blood flow. METHODS: Eighteen mongrel dogs were divided into three groups according to drug administration after hepatic reperfusion; control group (group C, n = 6), NTG group (group N, n = 6), and NTG with dopamine group (group N-D, n = 6). After femoral arterial and central venous catheterization, a midline abdominal incision was made, and the hepatic artery (HA) and the portal vein (PV) were exposed for clamping and declamping. Thereafter, the right renal artery was exposed, and a doppler probe for measuring RBF was placed around the right renal artery, and a thermal diffusion microprobe was inserted in the renal outer cortex to measure RCP. Hemodynamics, RBF and RCP, were repeatedly measured before and after HA and PV reperfusion. RESULTS: No significant change in heart rate was observed in any group. The BP decreased in all the groups after HA and PV occlusion. In group C, the BP recovered to the baseline level after hepatic reperfusion but not in groups N and N-D. The RBF and RCP decreased in all groups after HA andPV occlusion. The RBF increased compared to baseline in N-D after hepatic reperfusion, and the RCP increased versus baseline in N-D, 10 minutes after hepatic reperfusion. CONCLUSIONS: In conclusion, it was observed that the RBF and RCP increased compared to baseline by administering dopamine during HA and PV reperfusion. Therefore, the prophylactic administration of low dose dopamine during hepatectomy offers an effective method of protecting renal function.
