Ki-1 monoclonal antibody is a well known marker for Reed-Sternberg cells in Hodgkin's disease, but also occasionally reacts with activated lymphoid cells of either benign or malignant nature. Recently, Ki-1 antibody positive Non-Hodgkin's lymphoma, usually of large cell and/or polymorphous type, has been reported in the lymph nodes, skin, soft tissue, and stomach, but not in the bone. We report a case of multifocal primary bone lymphoma in a seven-year old body involving the left shoulder and right frontal bone, which proved to be a large cell, polymorphous lymphoma, helper T-cell type expressing Ki-1 antigen.

The purpose of this study was to compare surface roughness and bone formation around two types of threaded commercially pure titanium implants manufactured by two different companies. The test implants were manufactured by Sumin synthesis dental materials Co. (Avana, Busan, Korea), while the controls were manufactured by Nobel Biocare (MK II, Goteborg, Sweden). To compare bone formation adjacent to newly product with Branemark MK II implant, surface roughness was measured by Accurate 1500M and histomorphometric analysis was done. The results were as follows : 1. Measurement of surface roughness showed that Avana implant had a slightly more irregular surface compared with Branemark implant. 2. In the light microscopic studies, no infiltration of inflammatory cells nor the giant cells wee observed on both groups. 3. In th light and fluorescent microscopic studies, the amount of osseointegration and the extent and the timing of bone formation were similar. 4. There were no statistically difference between two groups in the average bone to implant contacts. Branemark implant ; 67%(SC 23%), Avana implant ; 70%(SD 16%). Comparing with Branemark implant, Avana implant made of CP grade II titanium showed similar good bone healing, formation and osseointegration.

Cytophagic histiocytic panniculitis is a rescently described histiocytic disorder. It is characterized by the presence of fever, pancytopenia, and subcutaneous nodules resulting from the infiltration of lympho-histiocytes in the dermis and subcutaneous adipose tissue. The characteristic findings is presence of bean-bag histiocytes containing phagocytized red blood cells, lymphocytes, and platelets. We experienced two cases of cytophagic histiocytic panniculitis with hard and erythematous subcutaneous nodules. These skin lesions exhibited infiltration of the subcutaneous tissue by large, benign histiocytes with cytophagic features. Hemophagocytic histiocytes were observed in the cervical lymph node in case 1, and bone marrow in case 2. One patient is alive, while the other one died with hemorrhagic complications.

BACKGROUND: Dopamine is an inotropic agent that is often selected for continuous infusion. For hemodynamic stability, the rate of infusion is controlled in the range of 5-15 µg/kg/min. This study aimed to compare the time intervals from the administration of dopamine to the onset of its hemodynamic effects when dopamine was administered through three different peripheral veins (the cephalic vein [CV], the great saphenous vein [GSV], and the external jugular vein [EJV]). METHODS: Patients in group 1, group 2, and group 3 received dopamine infusions in the CV, GSV, and EJV, respectively. A noninvasive continuous cardiac output monitor (NICCOMO™, Medis, Ilmenau, Germany) was used to assess cardiac output (CO) and systemic vascular resistance (SVR). Six minutes after intubation, baseline heart rate (HR), systolic blood pressure (BP), diastolic BP, mean arterial pressure (MAP), CO, and SVR values were recorded and dopamine infusion was initiated at a dose of 10 µg/kg/min. Hemodynamic changes at 0, 4, 8, 12, and 15 minutes postinfusion were recorded. RESULTS: No statistically significant differences were observed among the three groups with respect to the rate of hemodynamic change. In all groups, systolic BP, diastolic BP, MAP, and SVR tended to increase after decreasing for the first 4 minutes; in contrast, HR and CO decreased until 8 minutes, after which they tended to reach a plateau. CONCLUSIONS: For patients under general anesthesia receiving dopamine at 10 µg/kg/min, there were no clinical differences in the effect of dopamine administered through three different peripheral veins.

We report an autopsy case of amniotic band syndrome exhibiting microcephaly, asymmetric encephalocele, microphthalmia, nasal deformity, cleft lip and palate accompanied by left maxillary and zygomatic bone deformities. The amniotic membrane of the placenta was also attached to the herniated brain. The twenty-year-old primigravid mother had no history of taking drug, irradiation, infection or trauma before or during pregnancy.

PURPOSE: The purpose is to evaluate the CT or MRI findings to help in the differentiation between benign and malignant meningiomas. MATERIAL AND METHODS: The CT and MRI findings of 8 patients with surgically proven malignant meningioma were reviewed. Four cases of 8 malignant meningiomas and 18 cases of 27 benign lesions were studied with a 1.5T or 0.5T MRI. Radiologic analysis was focused on the heterogeneity of tumor, grade of peritumoral edema, presence of cystic degeneration and calcification, tumoral enhancement pattern, dural enhancement, and tumoral border. RESULT: Histologic types of malignant meningioma were meningotheliomatous (n=4), papillary(n=1), fibroblastic(n=l), angioblastic(n=l), and sarcomatous(n=l). Tumoral Heterogeneity was seen in 8 of 8 malignant lesions(100%) and 8 of 27 benign ones(30%). (p<0.01) Marked peritumoral edema was seen in 8 of 8 malignant lesions(100%) and 2 of 27 benign ones. (7.3%)(p<0.01) Most of malignant lesions(6 of 8 cases, 75%) showed ill defined border. Calcification was not present in malignant lesions in contrast with benign ones (14 of 27 cases, 52%). (p<0.05) No statistical significance was noted in cystic degeneration, dural tail like enhancement or tumoral enhancement pattern between malignant and benign meningiomas. MRI signal intensity of malignant meningiomas was homogeneously or heterogeneously hypointense on T1WI, heterogeneously isointense or hypointense on T2WI and heterogeneous or mixed on Gd-DTPA enhancement study. CONCLUSION: The CT or MRI findings such as heterogeneity, ill defined tumoral border, marked peritumoral edema, and absence of calcification may suggest the possibility of malignancy in meningioma.

OBJECTIVES: This study compared attitudes toward antipsychotic treatment according to awareness of the name of their illness in patients with schizophrenia. METHODS: Information on sociodemographic and clinical characteristics, including awareness of the importance of antipsychotic treatment, was obtained through a self-report questionnaire. The Drug Attitude Inventory (DAI) was administered. The data were compared according to awareness of the name of their illness. RESULTS: The study analyzed data for 199 patients with schizophrenia. Of these, 115 patients (57.8%) were aware that their illness was called schizophrenia, while 84 patients (42.2%) knew it by their psychotic symptoms or as another mental illness, such as depression. The patients aware of the name of their illness had significantly longer durations of illness and higher scores on the DAI. They were significantly more likely to have stopped taking medication on their own accord and to agree with the importance of antipsychotic treatment. Statistical significance was sustained in a logistic regression analysis after adjusting for the duration of illness and study site, except for the DAI score, which had borderline significance (p=0.055). In subjects with duration of illness > or =5 years, patients aware of the name of their illness had significantly higher scores on the DAI. CONCLUSION: Awareness of the name of their illness was associated with awareness of the importance of, and a positive attitude toward, antipsychotic treatments in patients. Psycho-education, including telling the patient the correct name of his or her illness, might be needed for maintaining antipsychotic treatment in patients with chronic schizophrenia.

In patients with Sjögren syndrome, decreased salivary flow result in reduced buffering capacity, which leads to the gradual erosion of enamel and significant tooth wear in both anterior and posterior teeth. The tooth wear often causes the loss of anterior and lateral guidance, occlusal disharmony, and insufficient space for prosthetic restorations, leading to functional and esthetic challenges, as well as complex occlusal issues. To address these issues, applying standardized cusp angles can help achieve long-term stability in occlusal contacts, allowing for a functional and stable occlusion with minimal adjustments during centric and eccentric movements.This case report presents a patient with Sjögren syndrome who exhibited severe wear in the maxillary and mandibular anterior and posterior teeth. Through prosthetic rehabilitation using standardized cusp angles, occlusal stability was improved, and esthetic outcomes were achieved, highlighting the effectiveness of this approach in restoring both function and esthetics.
