Ascariasis is probably the most common helminthic infestation of man, but it seldom causes severe illness. Pathologic conditions of Ascaris may be caused by adult worms, eggs or larvae. We describe a case of Ascaris egg granulomas that were found incidentally on the surface of the liver in a 75-year-old woman who had undergone a segmentectomy for an intrahepatic stone. Grossly, there were several yellowish calcific nodules of 0.4 cm in diameter on the lateral surface of the left lobe of the liver. Microscopically, the lesions were located in the hepatic capsule and consisted of fibrocalific nodules with many eggs. The eggs were round to oval, thick-shelled and measured 50~75x30~50 um. Most of the morphologically preserved eggs were fertilized eggs, but they had smooth shells without external protein coats. This case is of interest for the unusual location of the lesion, the presence of eggs without mammillation, and the association with the intrahepatic stone.

Rabies is a fetal viral encephalitis to which all mammals, including man are susceptible. This virus, the genus of Rhabdovirus, is usually present in the saliva of infected animals and is transmitted by their bite. As a rule the virus enter the CNS by ascending along peripheral nervous system and extremely variable in extent. Negri bodies are appear in about 75% of cases. These bodies are eosinophilic, usually rounded inclusions and is located in the cystoplasm of the neurons, most frequently in the pyramidal neurons of the Hippocampus and the Purkinje cells of the cerebellum. We have experienced a case of canine rabies that showed Negri bodies in the Purkinje cells along with diffuse degenerative encephalitis and perivascular mononuclear cells infiltration. The Negri bodies were best demonstrated by Negri body staining although routine H-E staind was also useful. There inclusion bodies were located exclusively in the cytoplasm, and were found occasionally. Electron microscopic findings of the Negri bodies showed aggregates of bulletshaped nucleocapsids. We report a Negri body found in the brain of rabid dog with the light and electron microscopic findings.

BACKGROUND: Carbapenem-resistant Enterobacteriaceae (CRE) with acquired metallo β-lactamase (MBL) resistance have been increasingly reported worldwide and associated with significant mortality and morbidity. Here, an outbreak of genetically related strains of Klebsiella pneumoniae producing the imipenemase (IMP)-1 MBL in a medical intensive care unit (MICU) in Korea is reported. METHODS: Since isolating carbapenem-resistant K. pneumoniae (CRKP) at the MICU of the hospital on August 10, 2011, surveillance cultures for CRE in 31 hospitalized patients were performed from August to September 2011. Carbapenem resistance was determined based on the disk diffusion method outlined in the Clinical and Laboratory Standards Institute guidelines. Polymerase chain reaction (PCR) was performed for genes coding for β-lactamase. Associations among isolates were assessed via pulsed-field gel electrophoresis (PFGE). In addition, a surveillance study of environmental cultures and health-care workers (HCWs) was conducted in the MICU during the same time frame. RESULTS: During the study period, non-duplicated CRKP specimens were discovered in four patients in the MICU, suggestive of an outbreak. On August 10, 2011, CRKP was isolated from the sputum of a 79-year-old male patient who was admitted to the MICU. A surveillance study to detect additional CRE carriers by rectal swab revealed an additional three CRKP isolates. PCR and sequencing of the four isolates identified the presence of the IMP-1 gene. In addition, PFGE showed that the four isolated strains were genetically related. CRE was not identified in specimens taken from the hands of HCWs or other environmental sources during surveillance following the outbreak. Transmission of the carbapenemase-producing Enterobacteriaceae strain was controlled by isolation of the patients and strict contact precautions. CONCLUSIONS: This study shows that rapid and systemic detection of CRE and strict infection controls are important steps in preventing nosocomial transmission.

We present a patient who developed a pseudolymphoma after ear piercing. A patch test showed gold sensitivity. Therefore, long standing dermal exposure to gold from a pierced-type earring might have produced the patient's disease. This patient did not respond to an intralesional steroid injection and was finally treated with a complete resection of the lesion. It is proposed that every patient with a hyperplastic lesion in the ear lobe should be taken a biopsy in order to rule out the possibility of a pseudolymphoma. When a pseudolymphoma develops in the ear lobe, a complete surgical excision could be the treatment of choice, especially for the prevention of recurrence.

OBJECTIVE: Flow cytometric deoxyribonucleic acid (DNA) content analysis has been shown to be of prognostic importance in some cancers. In this study, DNA patterns obtained by flow cytometry in patients with cervical cancer have been shown to be related to a prognostic importance in cervical carcinoma. METHODS AND MATERIALS: We retrospectively reviewed 59 cervical cancer patients who admitted to the department of obstetrics and gynecology, Samsung Medical Center firom January 1995 to May 1997. RESULTS: A total of 59 archival paraffin-embedded blocks were proc 42.4 percent were found to be DNA content aneuploid (DNA-A) and 57.6 percent DNA content diploid (DNA-D). The S-phase fraction was significantly increased with stage. The incidences of aneuploid and relative DNA index were not significantly increased with the stage(P=0.280) and age of patients(P=0.088). The results had no significant differences between the squamous cell carcinoma and adenocarcinoma, and no relationship between the groups with keratinizing cell type and nonkeratinizing type(P=0.409). The DNA ploidy patterns were not significantly correlated with metastasis to lymph node(P=0.179), tumor size(P=0.109), invasion depth(P=0.361) and recurrent group(P=0.285). High S-phase fraction had a tendency to correlate with the invasion depth(P=0,011), size(P=0.027), lymph node metastasis(P=0.039) and recurence(P=0.099) of cervical cancer. CONCLUSION: Flow cytometric DNA content analysis is being used more frequently in the management of different malignant tumors. Our study shows that DNA content analysis may not serve as an important biological indicator in determining the prognosis in cervical carcinoma, but High S-phase fraction has been connected with more aggressive tumors.

BACKGROUND: Antimicrobial resistance of Streptococcus pneumoniae presents a challenge to the clinicians in developing countries, particularly against the acute respiratory tract infections, including pneumonia. The present study was to evaluate the carriage rate and the antimicrobial resistance of S. pneumoniae isolated from children at a day-care center. METHODS: Oropharyngeal swabs were done every month for one year in 64 children at a day-care center in Seoul, Korea. Minimum inhibitory concentrations (MICs) of 9 antimicrobial agents (penicillin, ceftriaxone, cefuroxime, erythromycin, chloramphenicol, tetracycline, vancomycin, ciprofloxacin, cefpirome) were determined by agar-dilution method. RESULTS: The ages of the children ranged from 13 to 60 months (mean: 31 months). The overall carriage- rate of pneumococci was 26%, which was highest in December (46%) and lowest in July (3%). A total number of 105 strains of S. pneumoniae were isolated from 404 throat swabs and 68 strains among these were available for MIC tests. Only 8 (12%) strains were susceptible to penicillin, while 50 (73%) were intermediate and 10 (15%) were resistant. The isolates also exhibited high rates of resistance to other beta- lactams (53% and 21% were resistant to cefuroxime and ceftriaxone, respectively). The resistance rates to the other antimicrobial agents were also remarkable; 90% and 88% were resistant to erythromycin and tetracycline, respectively. However, 75% of isolates were susceptible to chloramphenicol and 100% were susceptible to vancomycin. CONCLUSION: There was a high rate of pharyngeal carriage of penicillin-resistant S. pneumoniae among children attending day-care center. Surveillance of pharyngeal cultures may provide useful information the treatment guideline of pneumococcal infections.

BACKGROUND: Complete clearance of the lesions by using calcipotriol alone have not been re-ported commonly in the treatment of psoriatic patients. Moreover, lesional and perilesional irritation are reported in some patients using calcipotriol, which may result in premature termination of the treatment due to impairing the compliance. OBJECTIVE: A clinical study was conducted to determine whether, in the topical treatment of psoriasis, a combination of calcipotriol cream and methylprednisolone aceponate was more effective than calcipotriol monotherapy. METHODS: Twenty-one psoriasis patients who had the symmetric lesions on the right and left lower legs were enrolled in the study. A combination of calcipotriol cream and methylprednisolone aceponate therapy was done on the left lower legs, whereas calcipotriol alone was applied on the right lower legs twice daily. PASI score and adverse events were recorded at each visit (1, 2, 3, 4, 6 week). The overall therapeutic result was also assessed by the physician and patients. RESULTS: The initial PASI score was 7.09 on both legs. After 6 weeks, the mean PASI score was 3.85 on the left leg, and 5.70 on the right leg (p<0.05). In the physicianOs global assessment, the percentage of patients who showed the improvement of more than half of lesions was 29% in the monotherapy and 62% in the combination therapy area. Two patients complained of mild itching sense on monotherapy, but there was no specific side effect on combination area. CONCLUSION: The combination therapy was more effective, as assessed by all evaluated variables. Furthermore, this combination reduces the adverse effects caused by long-term use of topical corticosterois as well as the irritation associated with. calcipotriol.
