Tuberculosis of parotid gland is extremely rare, even in countries where tuberculosis is endemic. It can occur by systemic dissemination from a distant focus or as primary involvement. Because of the clinical and radiological similarity, parotid tumor and parotid inflammatory disease take priority over the tuberculosis of parotid when it comes to differential diagnosis. As a result, clinicians often fail to make a timely diagnosis of tuberculosis of parotid gland in patient with a slowly growing parotid mass. However, its treatment is primarily medical if the positive diagnosis is well established. We have recently experienced a case of tuberculosis of parotid gland that was considered as the benign tumor preoperatively, but which was confirmed as tuberculosis of parotid gland after extracapsular dissection. We report it with a review of literature.

Common dental procedures(dental extraction & minor operation) are potentially stress-inducing in many patients, especially medically compromised patients. The body's response to dental stress involves the cardiovascular system(an increase in cardiovascular workload), the respiratory organ and the endocrine system(change in metabolism). To minimize the stress to the medical risk patient, the stress reduction protocol was established. The obtained contents were as follows: (1) Recognize the patient's degree of medical risk (2) Complete medical consultation before dental therapy (3) Schedule the patient's appointment in the morning (4) Monitor and record preoperative and postoperative vital signs (5) Use psychosedation during therapy (6) Use adequate pain control during therapy (7) Short length of appointment: do not exceed the patient's limits of tolerance (8) Follow up with postoperative pain/anxiety control (9) Telephone the higher medical risk patient later on the same day that treatment was given Though the stress reduction protocol above was applied to the dental extraction in medically compromised patients with the advanced infected teeth, the final responsibility for the complications (syncope, bleeding & infection, etc.) in a patient rests with the dentist who ultimately treats him. For the prevention of postextraction complications & poor prognosis, the authors treated the advanced infected teeth with the pulp extirpation, opening drainage through the canal and complete occlusal reduction. The final extraction and wound closure were then done after 1~2 weeks. The final prognosis was comfortable without common complications.

In the treatment of aortoiliac disease, two methods could be considered. One is percutaneous transluminal angioplasty, and the other is bypass graft. However sometimes two methods could be combined in high risk patients with a lengthy unilateral occlusion of one iliac artery and less extensive obstruction of the contralateral one, since higher risk aortofemoral bypass surgery may be obviated by femoro-femoral bypass graft after percutaneous treatment of the less diseased iliac artery. We report two cases of arortoiliac disease treated with Strecker stent followed by femoro-femoral bypass graft.

Neutrophils play a key role in innate immunity, and the identification of new stimuli that stimulate neutrophil activity is a very important issue. In this study, we identified three novel peptides by screening a synthetic hexapeptide combinatorial library. The identified peptides GMMWAI, MMHWAM, and MMHWFM caused an increase in intracellular Ca2+ in a concentration-dependent manner via phospholipase C activity in human neutrophils. The three peptides acted specifically on neutrophils and monocytes and not on other non-leukocytic cells. As a physiological characteristic of the peptides, we observed that the three peptides induced chemotactic migration of neutrophils as well as stimulated superoxide anion production. Studying receptor specificity, we observed that two of the peptides (GMMWAI and MMHWFM) acted on formyl peptide receptor (FPR)1 while the other peptide (MMHWAM) acted on FPR2. Since the three novel peptides were specific agonists for FPR1 or FPR2, they might be useful tools to study FPR1- or FPR2-mediated immune response and signaling.

We report a 62-year-old woman with a simultaneous occurrence of posterior reversible encephalopathy syndrome (PRES) and Guillain-Barre syndrome (GBS). The simultaneous presence of PRES in GBS is unusual and can easily escape recognition, with potentially serious consequences for the patient. Previous reports showed that the simultaneous or initial manifestation of PRES in GBS is more common in elderly female. The preponderance of female in older age may be due to age and gender related difference in sympathetic nerve activity.

BACKGROUND: The major value of mammography lies in the detection of nonpalpable breast carcinomas and the mammographic appearance of clustered microcalcifications, and its predictive value in carcinomas of the breast has long been a subject of interest. Since the introduction of the fine needle localization biopsy, surgeons have performed biopsies for nonpalpable breast lesions, but there are many controversies over determining the guidelines for biopsy with only the findings of mammography. METHODS: We reviewed the correlations between the type of mammographic appearance and the histopathologic diagnosis in 74 women who had nonpalpable breast lesions that appeared only as microcalcifications on the mammograms. We subdivided the types of microcalcifications into a casting type, a crushed-stone-like type and an amorphous type. The casting type has linear and branching patterns of microcalcifications, the crushed-stone-like type has clusters of granular microcalcifications, and the amorphous type has small punctuate powdery microcalcifications arranged irregularly. RESULTS: The patients ages ranges from 25 to 82 years and 15 cases (20.3%) of breast cancer were detected among the 74 cases. Four (4) cases (28.6%) of breast carcinoma were detected in the 14 casting type cases, 8 (24.2%) in the 33 crushed-stone-like type cases, and 3 cases (11.1%) in the 27 amorphous type cases. The mean sizes of the benign and the malignant lesions were 13.11+/-11.72 mm and 12.47+/-9.46 mm, respectively, but there was no difference in size between breast carcinomas and benign lesions. CONCLUSION: We conclude that women who have microcalcifications on their mammography should undergo biopsy, especially in cases of casting type or crushed-stone-like type microcalcifications to detect breast carcinomas at an early stage.

OBJECTIVES: Power spectrum analysis decomposes the heart rate signal into its frequency components and facilitates separation of sympathetic (low frequency) and parasympathetic (high frequency) activity. In congestive heart failure, augmented sympathetic tone and decreased parasympathetic tone were found. Autonomic nervous system was normalized 6 months after myocardial infarction. So we compared the autonomic nervous system activity by the heart rate variability in congestive heart failure and old myocardial infarction. METHODS: The protocol involved 20 healthy subjects (Group 1), 5 congestive heart failure patients not caused by myocardial infarction (Group 2), 4 congestive heart failure patients due to myocardial infarction and 11 old myocardial infarction patients without heart failure. We took 24 hour Holter monitoring by Del Mar Avionic tape recorder. All Holter tapes were analyzed with use of Model 563 Stratascan Holter Analysis System. We computed power spectra on each 256 sec segment of each hour during 24 hour recording. So, RR interval, SD of RR interval by time domain, and LF, HF, LF/HF ratio, Total PSD by frequency domain were measured. RESULTS: In congestive heart failure, nocturnal HF peak and diurnal variation of LF/HF ratio was decreased relative to healthy subjects. Nocturnal HF peak in old myocardial infarction was not visualized. All of LF, HF and Total PSD in congestive heart failure and old myocardial infarction patients relative to healthy subjects. CONCLUSION: On heart rate variability analysis using by 24 hour Holter monitoring, abnormal autonomic nervous activity was demonstrated in congestive heart failure and old myocardial infarction patients relative to healthy subjects.
