Acinic cell carcinoma is a rare salivary gland carcinoma, usually being found in the parotid gland and is uncommon in the other major and minor salivary glands. The tumor cells consist of either serous or mucous acinar cells with few ductal or myoepithelial cell elements. The tumor is a low-grade malignancy with slow growth potential. Surgical therapy depends on tumor size and the extent of infiltration into neighboring tissues. Superficial parotidectomy or total parotidectomy is the initial method of therapy in case of acinic cell carcinoma on parotid gland. When regional neck lymph nodes are involved, the operation is combined with a neck dissection, or with radiation therapy. In the short follow up period, acinic cell carcinoma has good prognosis with 5 year survival rate after surgery is over 80%. In the long-term follow-up, however, there is a tendency to increase in recurrence or metastasis. We experienced a case of acinic cell carcinoma of the parotid gland in a 57-year-old female, so we report it with literatures review.

Primary intraosseous carcinoma(PIOC) is defined as a squamous cell carcinoma arising within the jaw, having no initial connection with the oral mucosa. The squamous cell carcinoma within the bone can be presumably developed from residues of the odontogenic epithelium, therefore, it is seen in the jaw only. Metastatic carcinoma from another primary site should be excluded in the diagnosis of Primary Intraosseous Carcinoma. This is a case of 62-year-old man, who initially diagnosed as odontogenic cyst on maxilla, but its pathologic examination was diagnosed as squamous cell carcinoma with odontogenic cyst. We treated this patient with partial maxillectomy, modified radical neck dissection(mRND), and postoperative radiation therapy.

The purpose of this study was to develop the website-based program for individual meal planning. The program consisted of the basic information of clients, dietary habits, analysis of nutrient intakes and menu planning. The first part of the program consisted of general information such as general characteristics and anthropometric data of clients. The second part was designed to investigate the dietary habits, food intake frequency, nutrition knowledge, and drinking and smoking habits of the clients. The third part consisted of analysis of nutrient intakes including three major nutrients, calorie intake by foods and alcohol, and ratio of individual fatty acid intake. Nutrient intakes was evaluated by comparing with dietary reference intakes. In the final part, the program included the menu planning by using standard recipe. This system was also designed to insert, remove or change the food items or amount according to the user need. It is expected that the development of a meal planning system based on the internet can facilitate the professional dietary counseling, and thus help to improve the health of people.

PURPOSE: Recent advances in the methods of treating cancer in young patients have led to both an increased frequency of CNS complications as well as prolonged life expectancy. We intend to analyze the clinical aspects and laboratory findings of patients with CNS complications during and after treatment. METHODS: We reviewed the medical records of 174 childhood cancer patients treated with chemotherapy admitted to the Dept. of Pediatrics, Keimyung University Dongsan Hospital, from January 1995 to November 2002. Among them, 15 cases with CNS complications were investigated in this study. RESULTS: CNS abnormalities were found in 13 patients by CT or MRI during treatment such as leukoencephalopathy(n=7), mineralizing microangiopathy(n=4), brain infarction(n=3), intracranial hemorrhage(n=1), and hypoxic ischemic encephalopathy(n=1). It was found that two patients had two or more CNS abnormalities. Two patients who had no imaging abnormalities had convulsions, possibly after the addition of intrathecal methotrexate. The patients with intracranial hemorrhage and brain infarction had rapid and fatal clinical courses. The hypoxic ischemic encephalopathy following electrolyte imbalance completely recovered after correction of electrolyte. CONCLUSION: The CNS complications that occur during and after chemotherapy influence prognoses significantly, and remain neurologic sequelae. Therefore early diagnosis and prophylaxis for CNS complications and regular physical examination of patients who have recieved cancer therapy are strongly recommended.

This study was performed to assess the radiopacity of a variety of canal filling and retrograde root-end filling materials according to the specification concerning root canal obturation materials. Ten materials including Gutta-percha pellets, amalgam, Fuji II LC, Dyract(R) AP, Super EBA(R), IRM(R), AH 26(R), Sealapex(TM), Tubli-Seal(TM) and dentin were evaluated in this study. In the first part, densitometric reading of an each step of aluminum step wedge on occlusal film were performed at 60 kVp (0.2, 0.3, 0.4 s), 70 kVp (0.2, 0.3, 0.33 s) to decide appropriate voltage and exposure time. In the second part, ten specimens which are 5 mm in diameter and 0.5, 1.0, 1.5, 2.0, 2.5, 3.0 mm in thickness, were fabricated from each material studied. The specimens were radiographed simultaneously with an aluminum step wedge under decided condition (60 kVp, 0.2 s). The mean radiographic density values of the materials were transformed into radiopacity expressed equivalent thickness of aluminum (mm Al). The following results were obtained. 1. Among the various conditions including 0.2 s, 0.3 s, 0.4 s at 60 kVp and 0.2 s, 0.3 s, 0.33 s at 70 kVp, the appropriate voltage and exposure time that meet the requirement of density from 0.5 to 2.0 was 0.2 s at 60 kVp. 2. All of the materials in this study had greater radiopacity than the minimun level recommended by ISO No. 4049 standards. 3. Most of the materials had greater radiopacity than 3 mm Al requirement of ANSI/ADA specification No. 57 (2000) and ISO No. 6876 (2001) standards except for Fuji II LC and Dyract. It suggests that all experimental canal filling and retrograde root-end filling materials have a sufficient radiopacity that meet the requirement concerning root canal obturation materials except for Fuji II LC and Dyract.

Retropharyngeal hematomas are relatively rare. But, they are clinically important because of the close proximity of the retropharyngeal space to the upper airway. The authors experienced four cases of the retropharyngeal hematoma following cervical trauma, esophageal foreign body, stellate ganglion block, and discuss the diagnosis and treatment of individual condition.

PURPOSE: The aim of this study was to review the clinical characteristics and treatment outcome of pancreatitis developed in 19 children with leukemia and lymphoma in Asan Medical Center. METHODS: Hospital and outpatient records of 19 children either with leukemia or lymphoma who developed acute pancreatitis were reviewed. Clinical characteristics of these patients along with serologic data were analysed. RESULTS: 1. Median age at diagnosis of pancreatitis in 19 patients was 11 years of age. 2. Patients had acute lymphocytic leukemia (12 cases; 53%), acute myelocytic leukemia (4 cases; 21%), non-Hodgkins lymphoma (3 cases; 16%). 3. The etiologies of pancreatitis were L-asparaginase (16 cases) therapy, continuous Ara-C therapy (2 cases) and gallbladder stone (1 case). 5. L-asparaginase realated pancreatitis developed during the course of CCG 1882 induction (7 cases), CCG 1901 onsolidation (4 cases), CCG 1901 induction (1 case), and ADCOMP induction (1 case). 6. All patients experienced abdomial pain. Nausea, fever, vomiting, abdominal distention and diarrhea were also manifested clinically. 7. Hypocalcemia, sepsis, ascites, hyperglycemia, diabetic ketoacidosis, pancreatic pseudocysts and fistula were complicating events. 8. 6 patients were dead. The causes of death were from progression of lymphoma/ leukemia itself in 5 cases. One patient died of regimen related toxicity. The period of follow-up ranged from 2 months to 6.6 years with median follow-up of 28 months. CONCLUSION: 1. It is neccessary to monitor the level of serum amylase and lipase or to perform radiologic evaluation in patients who develop abdominal pain during L-asparaginase and Ara-C therapy especially in the course of CCG 1882 induction and CCG 1901 consolidation. 2. The outcome of chemotherapy induced pancreatitis is favorable in most instances but in some patients chronic pancreatitis may remain. The delay of chemotherapy due to pancreatitis may be responsible for the relapse of cancer. Therefore, prompt diagnosis and aggressive supportive therapy are important.
