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.

PURPOSE: The purposes of this study were to evaluate the marginal and internal gaps, and the potential clinical applications of three different methods of dental prostheses fabrication, and to compare the prostheses prepared using the silicone replica technique (SRT) and those prepared using the three-dimensional superimposition analysis (3DSA). MATERIALS AND METHODS: Five Pekkton, lithium disilicate, and zirconia crowns were each manufactured and tested using both the SRT and the two-dimensional section of the 3DSA. The data were analyzed with the nonparametric version of a two-way analysis of variance using rank-transformed values and the Tukey's post-hoc test (α = .05). RESULTS: Significant differences were observed between the fabrication methods in the marginal gap (P < .010), deep chamfer (P < .001), axial wall (P < .001), and occlusal area (P < .001). A significant difference in the occlusal area was found between the two measurement methods (P < .030), whereas no significant differences were found in the marginal gap (P > .350), deep chamfer (P > .719), and axial wall (P > .150). As the 3DSA method is three-dimensional, it allows for the measurement of arbitrary points. CONCLUSION: All of the three fabrication methods are valid for measuring clinical objectives because they produced prostheses within the clinically acceptable range. Furthermore, a three-dimensional superimposition analysis verification method such as the silicone replica technique is also applicable in clinical settings.

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.

Tuberculous granulomatous infection of the urinary tract is a rare complication of intravesical Bacille Calmette-Guerin (BCG) immunotherapy, which is commonly used for superficial urothelial cell carcinoma of the bladder. We present a case of tuberculous prostatic abscess in a patient who had undergone intravesical BCG immunotherapy for bladder carcinoma in situ.
