Strongyloides stercoralis is a nematodes and is prevalent in the tropical regions. In Korea, 6 cases have been reported in which the parasites were identified in feces. We report a case of hyperinfection syndrome with Strongyloides stercoralis confirmed in the tissue sections. A 52-year-old woman was admitted to the hospital because of generalized edema and weakness. She received steroid therapy for 30 years because of rheumatoid arthritis. One year ago, generalized edema and dyspnea were developed and she was diagnosed as minimal change nephrotic syndrome for which she received cyclosporin. On admission, she complained of generalized weakness and edema, multiple arthralgia and abdominal discomfort with nausea. The white-cell count was 14,600 without eosinophilia. A stool specimen was negative for occult blood, ova or parasites. Right lower quadrant abdominal pain and tenderness were developed, and the exploratory laparotomy was done under the impression of the acute appendicitis. An appendectomy with a biopsy of mesenteric lymph nodes was performed. From the 5th day after operation, the patient began to complain of the abdominal pain and constipation. Under the impression of adhesion bad formation, the laparotomy was done and disclosed that the proximal ileum was markedly dilated. On jejunotomy, a great amount of formed stool and barium was noticed in the proximal portion of small bowel. The jejunal tissue was biopsied. Grossly, the appendix was unremarkable. Microscopically, the inflammatory reaction was nearly absent, but in serosa, minute granulomas were found which contain a part of the parasite. Same feature was noted in the mesenteric lymph node. The biopsied jejunum contains numerous adult female, filariform and rhabdidiform larvae and eggs in the mucosa, submucosa and muscle wall. Their morphology was compatible with Strongyloides stercoralis. The patient died 5 days later in the state of multiple organ failure.

Chemically induced epiderml carcinogenesis is usually divided into two stages, the initiation and promotion. The initiation involves conversion of some epidermal cells into latent neoplastic cells and the promotion is proliferation of the transformed cells. As immunosurveillence is thought to be a host defense against tumors, Langerhans cells, being essential in initiation of local cutaneous immunologic reaction, is suggested to be important in the carcingenesis of the epidermis. This study is attempted to investigate the epidermal proliferative changes in mice induced by application of 12-0-tetradecanoy1-phorbol-13-acetate(TPA) on the skin initiated with 7, 12-dimethylbenzanthracene(DMBA) and its relationship with Langerhans cell. Ninty five male inbred BALB/c mice weighing 20~25 g were divided into five groups; the 33 week-group, the 21 week-group, the 12 week-group and the 4 week-group according to the duration of carcinogen application, and the control group. The carcingen was applied with a brush on the dorsal skin of mice after depilation. Ten days after application of 800 nmole DMBA in 0.4 cc acetone, 20 nmole TPA in 0.4 cc acetone was applied twice per week and the control group was applied with the same amount of acetone for 4 weeks. Animals were sacrificed 3 days after the last application of TPA. One hour before sacrifice, bromodeoxyuridine(BrdU) (1 mg/g) was injected via the tail artert for BrdU stain of S phase cells. A strip of dorsal skin was used for hematoxylineosin stain, immunohistochemical stain for BrdU and la antigen of Langerhans cell, and flow cytometry. The results are as follows: 1. Cellular proliferation, hyperkeratosis and dysplasia of the epidermis were increased in relation to duration of carcingen application. Papillomas were developed 12 weeks after application of the carcingen. 2. BrdU labelling and proliferative indices of the 20 weeks' application group were significantly higher than those of the 12 weeks' application group. The number of Langerhans cell was decreased markedly ater 4 week' application of the carcinogen. 3. All epiedrmal lesions including a case of squamous cell carcinoma were diploidy in flow cytometry. It is thought that disturbance of immunosurveillence, caused by depletion of Langerhans cell, may permit proliferation of epidermal cells. Although abnormal quantitative change of nuclear DNA has not occurred even when the epidermal proliferative activity and dysplastic change were increased markedly, it is thought that the occurrence of structural change of chromosome is remained to be clarified.

We reviewed 48 skin bicpsies obtained from 48 patients with epidermal nevus during a 10 year period from January 1981 to December 1990. The results are summarized as follows : 1) Of our 48 patients, 23 were male and 25 were female, and male to female ratio was 1 to 1.1. 2) The average of the patients was 19.8 years at the time of diagnois. 3) Lesions were present at birth in 45.7 percent of patients, and most of the remainder de veloped in childhood. The mean age of onset was 7.7 years. 4) The clinical varieties of the nevi in 48 patients were classified according to caicegories of nevus verrucosus, including systematized epidermal nevus, nevu, unius lateris, ichthyosis hystrix, epidermal nevus syndrome and inflammatory linear veirucous epidermal nevus. The most common type was nevus verrucosus(88.6%). 5) A large variety of histopathologic changes can be seen in epidermal nevi. The most common histopathologic .ype was nonspecific(31.3%), follows by common(12.5%), epidermolytic hyperkertosis(12.5%), and acanthosis nigricans(10.4%). 6) The most commonly affected area was head and neck(48.5%) followed by trunk(28.6%), upper limb(11.4%) and lower limb(2.9%).

Non-Hodgkin's malignant lymphoma is a relatively frequent lymphoreticular malignancy, and has been reported to constitute up to 5.2% of all malignant tumors in Korean patients. Various morphologic classifications of non-Hodgkin's lymphoma have been proposed, and among them, the Rappaport's classification has been most widely accepted. In 1982, a National Cancer Institute sponsored study on classification led to the creation of the Working Formulation in an attempt to resolve the controversy anddebate regarding the various classifications of non-Hodgkin's lymphoma. Angioimmunoblastic lymphadenopathy with dysproteinemia and polymorphic reticulosis are lymphoreticular proliferative disorders which have reported to transform to malignant lymphoma. The purpose of the present study is to reclassify non-Hodgkin's lymphomas according to the Working Formulation and to investigate the histopathological and immunocytochemical characteristics of angioimmunoblastic lymphadenopathy with dysproteinemia and polymorphic reticulosis. This study reviewed 300 cases of nodal and extranodal non-Hodgkin's lymphoma, 26 cases of polymorphic reticulosis, and 7 cases of angioimmunoblastic lymphadenopathy with dysproteinemia examined in the Departments of Pathology, Yonsei University College of Medicine, Youngdong Severance Hospital and Yonsei University Wonju College of Medicine from January 1977 to December 1986. In non-Hodgkin's lymphoma, each case was classified according to the Working Formulation and the Rappaport classification. All angioimmunoblastic lymphadenopathy with dysproteinemia and polymorphic reticulosis cases were subjected to histopathological analysis and a review of the clinical records. Immunocytochemical studies were done using kappa and lambda chains for B-cell markers and alpha-1-antichymotrypsin for histiocytic marker. The results obtained were as follows; 1) Among 300 cases of non-Hodgkin's lymphoma, the primarily involved tumor sites were the lymph nodes (141 cases), the gastrointestinal tract (67 cases), and the tonsils (32 cases) in descending order of frequency. 2) Using the Working Formulation, intermediategrade lymphomas occurred in 66.4% of the patients, and the most common subtype was "diffuse, large cell" (32.7%). By the Rappaport classification, 3 patients had nodular lymphomas, and "diffuse, histiocytic" was the most common subtype. 3) Infarction was present in 32 cases in which the "diffuse, lagre cell" type was most frequently associated. 4) In immunoperoxidase stains of 7 cases of angioimmunoblastic lymphadenopathy with dysproteinemia, proliferating immunoblasts revealed a polyclonal positivity for kappa and lambda chains. Atypical reticulocytes present in 26 cases of polymorphic reticulosis revealed a negativity for kappa, lambda and alpha-1-antichymotrypsin.

Korean Journal of Medicine 2020;95(2):104-113
Background/Aims:
Although the number of domestic adverse drug reactions (ADRs) reported in Korea is rapidly increasing, the analysis of ADRs in cancer patients remains limited. We sought to investigate the clinical features of ADRs in cancer patients.
Methods:
ADR data were collected from a spontaneous reporting system at single university hospital, between July 2010 and June 2015. ADR cases assessed to be “unlikely” or “unclassifiable” as per the criteria of the World Health Organization-Uppsala Monitoring Center were excluded. Additional medical information was retrospectively collected from chart reviews, and clinical features of ADRs were analyzed.
Results:
In total, 1,455 cases were reported. Of these, 822 ADRs (52.1%) were observed in cancer patients. The mean age of cancer patients was 60.8 years (range, 17–90 years), and 45.9% were male. The most prevalent clinical features were gastrointestinal abnormalities (32.6%), such as nausea and vomiting, followed by skin (28.5%) and neurologic manifestations (26.0%). Fifty-one (6.2%) and 296 cases (36.0%) were classified as severe and moderate, respectively. The most common causative agents were parenteral nutrition (PN) supplements (40.4%), followed by antibiotics (17.8%), analgesics (16.7%), iodinated contrast media (ICM, 10.6%), and vitamins (3.9%). Antineoplastic agents were responsible for 2.9% of cases. PN supplements were commonly associated with severe reactions.
Conclusion
Although it is well known that antibiotics, ICM, and analgesics induce ADRs, PN supplements, vitamins, and antineoplastic agents should also be considered as common causes of ADRs in cancer patients. Further investigation and monitoring to determine the causality associated with these agents is required.

Fascioliasis is a zoonotic disease caused by Fasciola Hepatica that infects mainly cattle, sheep, and goats. Humans can be infected by water or aquatic plants contaminated with metacercariae. The authors encountered two cases of F. hepatica infection. One patient reported abdominal discomfort with marked eosinophilia. The other patient had chest discomfort with marked eosinophilia. The abdominal CT images revealed hypodense lesions in the liver. The ultrasonography-guided liver biopsy findings in both patients were indicative of parasitic infections. Serological tests confirmed the definite diagnoses. Both patients were treated with a single dose of triclabendazole, which is the treatment of choice for fascioliasis. These findings suggest that a diagnosis of fascioliasis, particularly in the acute phase, should be considered in patients with abdominal pain, marked eosinophilia, and hypodense hepatic lesions on CT.

Allergy, Asthma & Respiratory Disease 2021;9(3):148-155
Purpose:
Inhalant allergens are known as a major factor for respiratory allergic diseases. There are many differences in sensitization rates of inhalant allergens, depending on the environment and demographic factors. This study aimed to compare the cross-sectional differences in sensitivity patterns to inhalant allergen between children, adolescents, and adults.
Methods:
We analyzed the results of 449 patients with asthma or allergic rhinitis who underwent the inhalant allergen skin prick test at our university hospital in 2016. The subjects were classified 5 groups according to age: children ( ≤ 12 years), adolescents (13–17 years), young adults (18–30 years), middle adults (31–64 years), and elderly group ( ≥ 65 years). Positive responses skin prick test for allergens were defined as allergen-to-histamine wheal ratio ≥ 1.
Results:
The sensitization rate (SR) to house dust mites (HDM) was 52.1% on average, showing the highest SR in all groups, especially in children (64.2%). Children and adolescents showed high SRs to cockroach along with tree pollen, animal fur, and adults showed high SR to weed pollen along with them. Among the tree pollen, the SRs to oak, alder, birch, and beech were high in all groups; in children, the SR to plain and willow tended to be high, and in adults the SR to hazel was high. SRs to Timothy pollen (9.9%) and Alternaria (8.6%) tended to be higher in children than in the other groups.
Conclusion
Although HDM is still the major allergen in children and adults with respiratory allergy, our study suggests various differences in the sensitization pattern to inhalant allergens according to age even in the same area. Further studies are needed to explain these differences in sensitization patterns.

Purpose:
Contact dermatitis (CD) is a common skin disease caused by various allergens that can be identified by patch test (PT). Despite the analysis of PT outcomes in various regions of Korea, no specific investigation has targeted the Busan area. We aimed to analyze PT results using Chemotechnique in patients suspected of CD in Busan.
Methods:
We reviewed medical records of 273 patients who underwent PT between 2019 and 2020 at two university hospitals in Busan. PT results were interpreted according to the International Contact Dermatitis Research Group criteria.
Results:
Among the patients, 86.4% exhibited positive reactions to at least one allergen. Those with positive outcomes displayed a higher comorbidity rate of chronic urticaria but a lower rate of atopic dermatitis. Moreover, they reported higher positivity rates to questions about sexual life and treatment on the Dermatology Life Quality Index questionnaire. Major allergens in Busan were cobalt chloride (60.1%), nickel sulfate (52.0%), and potassium dichromate (50.9%), followed by thiomersal, balsam of Peru, and fragrance mix (17.2%, 15.4%, and 13.9%, respectively). Captan, budesonide, and colophony were more prevalent allergens in males. While the positive rate for thiomersal were higher in the younger age group, balsam of Peru allergen was higher in the older age group.
Conclusion
This study represents the first PT analysis conducted in Busan, revealing metal-related allergen as the most common cause of CD, with variations observed across sex and age. Further research is needed to validate these findings and elucidate the sources and pathways of allergen exposure in Busan.
