Hemolytic anemia due to cold agglutinin disease is a known complication of Mycoplasma pneumoniae infection but is rarely observed, particularly in children. A case of Mycoplasma pneumonia complicated with hemolytic anemia is presented. A 7 year-old girl was adimitted because of fever, cough, sputum and pale appearance. Chest X-ray showed pneumonic consolidation of Rt. upper lobe, lingular division. Laboratory studies disclosed the following values : Hb 5.3g/dL, Hct 11.1%, reticulocyte 2.9%, indirect Coombs test negative, direct Coombs test(monovalent) Anti-C3d positive, Anti-IgG negative, Anti-IgM negative, cold agglutinin titer 1 : 256, mycoplasma antibody titer 1 : 640, total bilirubin 1.0mg/dL. Initial PBS before wanning showed agglutination of red blood cells. The diagnosis of cold agglutinin hemolytic anemia complicating mycoplasma pneumonia was made. And treatment with roxithromycin, prednisolone and avoiding cold exposure was initiated, and complete recovery ensued. We report a case of cold agglutinin hemolytic anemia complicating mycoplasma pneumonia in children.

The present investigation confirms the zoonotic significance of Microspoum canis infection in five patients who had direct contact with diseased dogs and cats. Typical ringworm type lesions were mainly encountered on the exposed areas of the body. M. canis was isolated from the cutaneous lesions of man ana infected pets ; and also directly demonstrated in skin materials. However, the fungus could neither be recovered from the non-contact group nor from the saprobic environment. The isolates from man, dog, and cat showed similar gross as well as microscopic morphology. Further genetic studies so indicated that all the human and animal isolates of M. canis were(-) mating type. It is believed that transmission of zoophilic dermatophytes from animal to man occurs more commonly with direct exposure. In addition, the epidemiology and preventive measures are also discussed.

Dirofilaria immitis parasitizes mainly in the pulmonary arteries and in the heart of dogs and cats. The parasite is also of public health importance, because it often elicits nodules in the pulmonary parenchyma and in the subcutaneous tissues, or sometimes parasitize itself in the eyes of human. In this study, we investigated the prevalence of heartworm infection among 165 dogs on three breeding farms in the vicinity of Seoul, Korea. Of 165 dogs, 83 dogs (50.3%) were infected with the parasite, as revealed by an antigen-detecting test using the peripheral blood. Of these, 23 dogs (20.2%) contained microfilaria using the peripheral blood, which are potential source of transmission to uninfected animals and to humans in the endemic area. None of infected dogs showed any clinical signs associated with the disease. Since the three farms were located in the vicinity of Seoul, the unexpectedly high infection rate could imply that the possibility of exposure of both animals and humans living in the metropolitan Seoul area to the parasite is higher than in the other area of Korea.

Erythema multiforme(EM), a blistering and ulcerative inflammatory disorder, affect skins or mucosa, and is thought to be triggered mainly by preceding infection, such as Herpes simplex virus, or exposure to drugs and medication, particular antibiotics or analgesics. Symptoms include typical cutaneous target lesions on skins and in case of oral manifestation, erosive and ulcerative lesions on lips, buccal mucosa, and tongue are known to occur, which needs differential diagnosis with other intraoral lesions. In this case, EM assumed that it is occurred by giving Trichomonas infection or Metronidazole in oral region is introduced with a review of diagnosis and treatment of EM.

Purpose: The purpose of this study was to investigate the level of knowledge, attitude and compliance with standard precautions and to identify predicting factors of compliance with standard precautions in ICU and ER nurses. Methods: The participants were 228 ICU and ER nurses working in one of three university hospitals and one general hospital. Collected data included general characteristics, features related to infection risk, and knowledge, attitude and compliance with standard precautions. For the final analysis, 218 questionnaires were used. Results: Within the previous one year, 103 (47.3%) nurses experienced pricking injury from syringe needles or other sharp materials, 111 (50.9%) nurses reported exposure to patients' blood and body fluid. In general, the scores for knowledge, attitude and compliance were all high. Compliance scores for nurses in intensive care units were significantly higher than those of nurses in emergency. There were significant correlations of knowledge, attitude, and compliance with standard precautions. Attitude and work place were significant factors predicting compliance with standard precautions. Conclusion: The results indicate that to increase nurse's compliance with standard precautions, continuous efforts to enhance positive attitudes and at the same time, improve work environments and use individualized approaches based on the work units are needed.

A murine leukemia x LM fibroblast hybrid cell line with immune augmenting properties stimulated resistance to Mycobacterium avium complex (MAC) in mouse peritoneal macrophages, and in immune deficient beige mice (C57BL/6/bgj/bgj). The proliferation of MAC in mouse peritoneal macrophages was inhibited by medium conditioned by the growth of the hybrid cells (hybrid cell-CM). Under similar circumstances, media conditioned by the growth of LM cells (LM cell-CM), a mouse fibroblast cell line used as one parent in forming the hybrid cell, was exhibited no inhibitory effect. Treatment of mouse peritoneal macrophages with hybrid cell-CM, but not with LM cell-CM, stimulated the expression of each of four previously described macrophage activation antigens, suggesting that the hybrid cells formed immunomodulators in addition to those formed by LM cells. Furthermore, the morphology of the macrophages following treatment with hybrid cell-CM was clearly distinguishable from that following exposure of the cells to LM cell-CM. The therapeutic effects of hybrid cells on the progression of MAC-infection were indicated by the prolonged survival of MAC-infected immune-deficient beige mice. One hundred percent of treated animals survived more than 60 days, while untreated animals died in approximately 22 days.

The maxilla rarely undergoes necrosis due to its rich vascularity. Maxillary necrosis can occur due to bacterial infections such as osteomyelitis. viral infections such as herpes zoster and fungal infections such as mucormycosis, aspergillosis etc. Herpes zoster is a common viral infection, the oral soft tissue manifestations of which are widely known and recognized. Extremely rare complications such as osteonecrosis, and secondary osteomyelitis in maxilla were observed. But, reports of spontaneous tooth exfoliation and jaw osteonecrosis following herpes zoster infection in the distribution of the trigeminal nerve are extremely rare in the literature. We report a case of maxillary necrosis by herpes zoster in an uncontrolled diabetic patient. There was extensive necrosis of the buccal and palatal mucoperiosteum and exposure of the alveolar bone. This patient was successfully treated using a removal of necrotic bone and nasolabial flap. We briefly discuss different diseases which can lead to maxillary necrosis and a review. Analysis of the pathogenesis of herpes zoster and bone necrosis are discussed.

Facial nerve paralysis(or Bell's palsy) which commonly occurs unilaterally, gives rise to paralysis of facial expression muscle. This condition is classified into symptomatic facial nerve paralysis due to intracranial tumor, post operative trauma, etc. and idiopathic facial nerve paralysis. To explain the etiology of idiopathic facial nerve paralysis, many hypothesis including ischemic theory, viral infection, exposure to cold, immune theory etc. were suggested, but there is no agreement at this point. The method to evaluate the facial nerve paralysis, when it occurs, consists of three stage scale method, image thechnics like CT and MRI, laboratory test to examine the antibody titers of viral infection, neurophysiologic test to evaluate the degree and prognosis of paralysis. Treatment includes medication, stellate ganglion block(SGB), surgery, physical therapy and other home care therapy. In medication, systemic steroids, vitamins, vasodilating-drug and ATP drugs were used. SGB was also used repeatedly to attempt the improvement of circulation and to stimulate the recovery of nerve function. Physical therapy including electric acupuncture stimulation therapy(EAST) and hot pack was used to prevent the muscle atrophy. When No response was showed to this conservative therapies, surgery was considered. After treating two patients complaining of Bell's palsy with medication(systemic steroids) and EAST, favorable result was obtained. so author report the case of facial nerve paralysis.

The author investigated the larvicidal action of liquid nitrogen against the metacercariae of Clonorchis sinensis, with an observation on the freshness and change of taste in the flesh of fishes. The results obtained were as follows: 1. The metacercariae in the mesh of Pseudorasbora parve, which were treated with liquid nitrogen ($-192^{\circ}C$), were not killed within 10 seconds, but completely killed over 30 seconds. In comparison, the metacercariae in the flesh of p. parka kept in a refrigerator ($-12^{\circ}C$) were killed only in 84% in 10-hour exposure group. 2. The freezing speed of fishes by liquid nitrogen was 4 min.(') and 15 seconds(") for Cyprinus carpio, 1'22" for Carassius carassius and only $30^{\circ}C$ for Pseudorasbora larva. 3. As for the freshness and taste of raw fresh water fishes, they were not deteriorated after the treatment with liquid nitrogen. 4. In animal infection experiment of C. sinensis metacercariae after freezing, they were found not infective after they were treated with liquid nitrogen. From the results, it is inferred that the treatment of fresh water fishes for longer than 30 seconds with liquid nitrogen is helpful to reduce the possibility of C, sinensis infection without alteration of the freshness and taste of fishes.

Purpose: Intestinal parasitic infections (IPIs) are a major health problem worldwide, especially in developing countries. According to the literature, children are more likely to get infected due to more frequent exposure to sources of infection. Methods: In this study, we collected 500 fecal samples from children under 15 years of age who referred to labs in Ilam city. All samples were microscopically examined using formalin-ether concentration and Trichrome staining techniques. The results were analyzed using SPSS 20.0. Results: Among 500 investigated samples, 4 types of parasites were detected. Giardia lamblia, Entameba coli, and Blastocystis hominis were identified as intestinal protozoa, and pinworm as intestinal worm. In this study, 23 cases (4.6%) had parasitic infections. 13 patients (2.6%) were infected with Giardia parasite, 4 patients (0.8%) with E. coli, 3 patients (0.6%) with B. hominis and 3 patients (0.6%) had pinworms. Conclusions: The findings of this study showed that the prevalence of IPIs among children aged under 15 years in Ilam is relatively down, which can be attributed of sufficient information of parents and children about the modes of parasite transmission and the important role of carriers in the pathogen cycle.
