Nine typical cases of ossifying fibroma in the tibia or fibula were retrospectively reviewed for clinical and histopathological aspects of this disease. Along with the case analysis, light and polarized microscopic examinations were performed in each case. Differential points with monostotic fibrous dysplasia were as follows; 1) ossifying fibroma begins in the significantly younger age, which is in most cases below 10 years of age, 2) it is confined to diaphysis of tibia or fibula, 3) radiologically, multilocular osteolytic destructive change in eccentric pattern is usually combined with anterior or anterolateral bowing deformity, 4) microscopically, characteristic findings are presence of osteoblastic rimming, peripheral maturation, and zonal phenomenon. In the treatment of ossifying fibroma, definitive surgical treatment should be delayed until skeletal maturity, when segmental resection in wide margin including periosteum might be preferred.

Tetanus is an infectious disease that causes muscle spasm with spastic paralysis and pain. Localized tetanus is rare and milder than the generalized form, however, it should be immediately treated because it may precede the onset of generalized form. The authors experienced a case of localized tetanus in both legs with abdominal pain after lumbar radiculopathy acupuncture treatment and here report this case with relevant literature reviews.

OBJECTIVES: To assess innate and humoral immune responses in middle ear effusion of obese pediatric patients with otitis media with effusion (OME). METHODS: We evaluated 219 children with OME, of whom 21 were obese and 198 were non-obese. We compared the expression in middle ear effusion of mRNAs encoding toll-like receptors (TLR) 2, 4, 5, and 9; nucleotide-binding oligomerization domains (NOD) 1 and 2; retinoic acid-inducible gene (RIG)-I; interleukins (IL)-6, -10, and -12; interferon (IFN)-gamma; and tumor necrosis factor (TNF)-alpha mRNAs. We also compared the expression of immunoglobulins IgG, IgA, and IgM and the bacterial detection rate in the two groups. RESULTS: TLR2-mediated expression of IL-6 mRNA, TLR4-mediated expression of IL-6 and IL-10 mRNA, TLR5-mediated expression of IL-6, IL-10, and TNF-alpha mRNA, TLR9-mediated expression of IL-6 mRNA, and NOD2-mediated expression of IL-6, IL-12, and TNF-alpha mRNA were significantly lower in obese than in non-obese children (P<0.05). However, concentrations of IgG, IgA, and IgM in middle ear effusion were lower in obese than in non-obese children, but none of these differences was significant (P>0.05). CONCLUSION: Mean body mass index was higher and pattern-recognition receptor-mediated cytokine mRNA expression was lower in obese than in non-obese children with OME.

PURPOSE: Most treatment decisions for breast cancer patients are based on an assesment of prognostic factors. Tumor markersB (p53, c-erbB2, bcl-2, Cathepsin D) have been evaluated for their prognostic factors and many studies suggest that these factors as assessed by immunohistochemistry (IHC) may be helpful for treatment decisions, while the risk group for high relapse can not be discriminated by single tumor marker alone. In order to obtain useful prognostic information, several tumor marker expressions must be combined and weighted. METHODS: The expressions of ER, PR, p53, c-erbB2, bcl-2, Cathepsin D were detected by IHC on paraffin-embedded sections from 449 primary breast cancer patients treated at Seoul National University Hospital between January 1996 and December 1998. In the present study, tumor marker expressions were analyzed along with conventional clinicopathologic factors. Additionally, correlations between various tumor marker expressions were examined and combinations of tumor marker expressions relating pathologic parameters currently in use for primary breast cancer prognosis were investigated. RESULTS: ER, PR, bcl-2, Cathepsin D expressions were related to smaller tumor size and PR was related to less axillary nodal involvement. ER, PR, bcl-2 expressions were related to good NG and HG, while p53 expression wasrelatedto poor NG and HG. ER and PR expression were related to bcl-2 expression, c-erbB2 expression was related to p53 expression and c-erbB2 expression was related to Cathepsin D expression. ER /bcl-2 was more prevalent in NG 1 and HG III tumors. ER /p53 and p53 /bcl-2 were more prevalent in NG 2/3 and HG I/II tumors. p53 /c-erbB2 was more prevalent in NG 1 tumors. CONCLUSION: Combinations of tumor marker expressions ER/bcl-2, ER/p53, p53/c-erbB2, p53/bcl2 provides more detailed information concerning cancer aggressiveness.

CONCLUSION: Combinations of tumor marker expressions ER/bcl-2, ER/p53, p53/c-erbB2, p53/bcl2 provides more detailed information concerning cancer aggressiveness.

PURPOSE: The purpose of this study was to demonstrate effects of a critical pathway (CP) for stroke patients seen in emergency rooms (ER). METHODS: The CP developed by the CP committee consisted of 8 criteria: behavior of doctors and nurses, laboratory tests, Image testing, medication, treatment, activity, and nutrition. According to application of CP, a control group (n=17) and experimental group (n=17) were defined. Time was checked by the electronic medical records. RESULTS: Use of CP for stroke patients in the ER, resulted in a decreased length of stay in ER (t=2.341, p=.026), and time required for image testing (t=2.623, p=.021), and an increased number of patients using rtPA (chi2=4.802, p=.049). Time required for neurology doctor contact, for neurology doctor to see patient in the ER, and for report of blood tests decreased, but there were no statistical significance. CONCLUSION: Quick responses are most important in the ER, so CP for these patients is a very effective patient management tool. To reduce delay in stroke diagnosis, continuous education programs for similar symptoms are necessary. CPs for other patients in the ER should be developed, and studies on cost and satisfaction, as well as length of stay, should be done.

Bilateral femoral neck stress fractures have been rarely reported. When diagnosed, they are usually limited to athletes or military personnel. A 35-year-old man, previously healthy, visited the emergency department for right inguinal pain. On physical examination, no external wound, tenderness or limitation of motion were found in either lower extremity. Plain radiography showed normal findings but an magnetic resonance image showed a linear fracture in the femoral neck. In this case, bilateral femoral neck stress fractures were found in a young non-athlete adult with no prior medical history of related injuries. Surgery is generally not performed for stress fractures but considering the patient's early mobilization and the need for quick reintegration into society, surgery was done in this case.

Soft tissue calcifications after burn injuries are commonly found in the periarticular region. They can easily be found because they cause severe pain and distress to the patient. However, a long period is required to identify extra-articular soft tissue calcification after burn injuries because they have no specific symptoms. Herein, we present the case of a patient with dystrophic extra-articular soft tissue calcification after a burn injury. A 70-year-old woman developed a non-healing ulcer in the right lower leg area two months before presentation to the hospital. She had third-degree flame burns on the anteromedial tibial area of the right leg approximately 40 years prior, and there had been no particular problem. Examination revealed chronic ulcers, and a review of radiograph findings revealed irregular calcification. The wound was treated with wide excision with a skin graft, and it healed without complications. During follow-up one month later, no recurrence of the calcification or ulceration of the lesion was found.
