PURPOSE: Neck masses are frequently encountered in pediatric practice, and have various underlying diseases. If the underlying diseases of the neck mass are not confirmed by its clinical characteristics, it can be done by neck mass biopsy. To define the necessity and the appropriate time of neck mass biopsy is very difficult and also important. Therefore the authers have conducted this study to have aids in differential diagnosis of neck mass in children by analyzing the clinical manifestations of underlying diseases of neck mass. METHODS: The authors have reviewed 390 children under 15 years of age who visited and admitted with neck masses to Shinchon Severance Hospital between Jan. 1987 and Dec. 1994. In order to elucidate the nature and etiologic diseases of neck masses, we classify and analyze the neck masses by age and sex distribution, duration of symptoms and signs, size and consistencies and by site and number of neck masses, and finally by underlying diseases. RESULTS: 1)Of the overall sex distribution, male patients were more than female, the male to female ratio was 1.32 : 1(222:168). The most common age group was 2-5 years of age. The most common acompanying symptoms were upper respiratory tract infection symptoms, comprising 37.7 % of all, and the most common duration of symptoms and signs was within 3 months, comprising 65.6 % of all. 2)Of the underlying diseases of the neck masses, the largest proportions were inflammatory masses, which comprising 49.2 % of all cases, among these, nonspecific cervical lymphadenitis was most common(65.6 %). 3)We could also confirm the nonspecific cervical lymphadenitis by clinical manifestations, blood exams and neck ultrasonography except neck mass biopsy. 4)For the diagnosis of tuberculous lymphadenitis, the family history of tuberculosis, PPD skin test, and chest X- ray findings are almost helpful, but the neck mass biopsy was essential. 5)Malignant tumors were 24 cases, which comprise 6.2 % of all. CONCLUSIONS: For the appropriate differential diagnosis of neck masses in children, we should observe and describe accurately the clinical characteristics of the neck masses. On physical examination, if we can not rule out the possibility of tuberculous lymphadenitis or malignant tumors, the neck mass biopsy should be done immediately, but if it is likely the nonspecific cervical lymphadenitis, we must wait until the size of neck masses decrease or other symptoms disappear after empirical antibiotics therapy.

OBJECTIVE: The aim was to assess the value of resistance index(RI) and pulsatility index(PI) to differentiate between benign and malignant ovarian tumors by color and pulsed Doppler ultrasound. METHODS: 129 ovarian tumors identified with ultrasound were referred for color and pulsed Doppler ultrasound evaluation to calculate the lowest RI and PI, and the corresponding histopathologic diagnosis was recorded. RESULTS: The intratumor artery waveforms were obtained in 37.1%(36 of 97) of benign tumors and in 91.0%(29 of 32) of the malignant group. RI and PI were lower in malignant tumors than in benign tumors(p<0.01). Also, there was a significant incremental decrease in both indices value from the benign tumor toward borderline malignancy(p<0.05) and to invasive ovarian cancer(p<0.01). But, there was no significant difference in both indices value according to the FIGO stage of ovarian malignancy. For RI cut-off value of 0.6, sensitivity and specificity were 89.7% and 91.7%; for PI cut-off value of 1.1, 86.2% and 91.7%. Therefore, the most accurate cut-off values of RI and PI were 0.6 and 1.1, respectively. CONCLUSION: RI and PI calculated by color and pulsed Doppler ultrasound can help in the diagnosis and selection of treatment plan of ovarian tumors, especially when the morphological finding of ovarian tumor is equivocal. And during the follow up of benign tumors, both indicies can give us the clue of malignant potential of benign tumors.

Although there are various methods of operative treatment for hony mallet finger, the operative technique is not so easy and complications such as joint stiffness, sott tissue prohlems, infection, change of nail shape and arthrosis are common. The authors performed operations for 26 cases of hony mallet fingers, fixing the hony frapment by Kirschner wire, pull-out wire suture and miniscrew respectively, from Jan. l988 to Jun. l996. The results were as follows. l. According to Niechajev's classification. there were 3 cases of type B, 7 cases of type C, l4 cases of type D, and 2 cases of type E. And 11 cases were accompanied hy crushing injury. 2. Involved fingers were third finger in 11cases, fit'th finger in 7 cases, fourth finger in 5 cases, second finger in 2 cases. and thumb in I case. 3. The hony mallet finger was caused hy occupational injury in l6 cases, direct blow in 7 cases and sports injury in 3 cases. 4. The fractured fragment was fixed hy Kirschner wire in 9 cases, by pull-out suture in 9 cases and by miniscrew in 8 cases. 5. The results were evaluated hy Kanies scale. Sixteen cases had satisfactory results. Seven cases (87.5%) were satisfactory in miniscrew fixations. 5 cascs (55.6%) in pull-out wire suture methocls and 2 cases (22.2%) in Kirschner wire tixations. 6. The complications were joint incongruity in 4 cases, dorsal prominece in 6 cases, painful limitation of motion in 2 cases which were treated by arthrodesis, pin site infection in 2 cases and hreakage of wire suture in 1 case. 7. The miniscrew fixation offered relatively firm fixation, low complication rate, and good results. so it can be considered as one of the good methods of treatment for hony mallet finger.

Chimeric antigen receptor (CAR) T-cell therapy constitutes a revolutionary advancement in personalized cancer treatment. During this treatment, a patient's own T cells are genetically engineered to express a synthetic receptor that binds a tumor antigen. CAR-T cells are then expanded for clinical use and infused back into the patient's body to attack cancer. CAR-T cells have produced remarkable clinical responses with B-cell malignancies. However, CAR-T cells therapy is not without problems. Barriers to effective CAR-T cells therapy include severe life-threatening toxicities and modest anti-tumor activity. In this review, we introduce the concept of CAR-T cells therapy, currently available CAR-T cells therapy options, and how to deal with adverse events.
