BACKGROUND: One of the main disadvantages of caudal block is the long latent period before a satisfactory blockade is obtained. Many investigators have used various preparations of local anesthetic solutions to improve the speed of onset. This study was performed to evaluate the effectiveness of prewarming of lidocaine HCl for caudal block. METHODS: Fifty healthy young patients (ASA I) were allocated into two groups, A and B. In group A, the local anesthetic solution were injected at room temperature (25 degrees C), while in group B, they were injected at 37oC. All the caudal block were performed using 2% lidocaine HCl 20 ml with fentanyl 100ug and epinephrine 1:200,000. The onset time was defined as the period from completion of injection until the patient first noticed loss of sensation to pin-prick on perianal region. Assessment of sensory loss was made at 15 seconds interval. We have compared the onset of sensory blockade between groups. The duration of analgesia and any significant side effects were also recorded. RESULTS: The onset of sensory blockade was significantly faster in group B (3.5 +/- 0.5 minutes) than group A (6.2 +/- 0.9 minutes). The duration of analgesia were not significantly changed between groups. Side effects of urinary retention, pruritus and nausea were noted between both groups but the difference was not significant. CONCLUSIONS: We have found that the onset time was 44% faster with warm lidocaine-fentanyl mixture (37 degrees C) than with the room temperature (25 degrees C). The improved clinical usefulness was achieved with no increase in side effects. The technique is a safe and effective method to reduce the latency of onset.

3.Simple Renal Cyst Treatment: Ultrasound-guided Aspiration Alone or with Instillation of 99% Ethanol into Renal Cyst.
Korean Journal of Urology 1990;31(6):915-920
Thirty-eight benign renal cysts in 35 patients were treated with or without 99% ethanol during diagnostic aspiration under ultrasonic guidance. All were followed by ultrasound from 3 to 59 months. There were twelve (80% ) recurrences in simple aspiration group. Two cases ( 6.25% ) were recurred in ethanol instillation group. All of the five symptomatic patients were relieved of subjective symptoms such as flank pain after alcohol instillation. Minor complications of local pain and temperature elevation were no more prevalent than with simple aspiration alone. There was no major complication. In conclusion, it is reasonable to treat and prevent of renal cyst by ablation of the cyst with alcohol at the same time as diagnostic procedure.

Background: Lumbar epidural anesthesia is widely used regional blockade method. But postepidural back pain is most common cause that experienced patients refuse epidural anesthesia. We planned this study to evaluate the effect of epidural dexamethasone injection for postepidural back pain. Methods: Adult patients free of back pain were randomly allocated into two groups. In both group anesthesia was induced with 2% lidocaine 20~25 ml mixed with 1:200,00 epinephrine and fentanyl 0.1 mg. After surgery, epidural catheter was removed after epidural dexamethasone injection in one group (group 2). In other group (group 1), catheter was removed without treatment. We visited patients and asked existence of back pain, and the intensity of back pain was measured by visual analogue scale at 24, 48 and 72 hours after surgery. Statistical analysis was done by Student's t-test and Mann-Whitney test. Results: In group 2, there was significant decrease in number of patients suffering from back pain and intensity of back pain. Conclusion: Epidural dexamethasone injection results in decreased number of patients suffering from back pain and also less in intensity of back pain.

99m Tc-pyrophosphate was investigated for use as an indicator of intestinal infarction in intussusceptedbowel. Irreducible intussusceptions were created in 18 rabbits by surgery. 99mTc-pyrophosphate was then injectedintravenously 6-12, 18, 24 and 30-40 hours later for external scanning. In 15 of the rabbits, infaractiondeveloped with intussusception, and 13 of them demonstrated increased uptake of 99m Tc-pyrophosphate on externalinvivo scintiscans. The remained 2 of them showed no evidence of increased uptake. So false negative cases were2(sensitivity 86.7%). The 3 rabbits without infarction showed no increased uptake of radionuclide. Specimenscanning confirmed increased uptake of radionuclide in the infarcted segments. These observations suggest that 99mTc-pyrophosphate is a reliable indicator of the intestinal infarction that sometimes occures with intestinal intussusception.

Tumors of the sacrum are relatively uncommon. The diagnosis is difficult, especially in the early phase of the disease, because the clinical manifestations are nonspecific, the clinical signs may be vague and the radiologic changes are needed to differentiate from intestinal gas shadow. The clinical features are sacral pain, sensory change on perineum, urination difficulty, constipation, and sciatica. Seven cases of sacral tumor were treated at the Department of Orthopaedic Surgery, Kyung Hee University, from October 1981 to October 1992, and the results were as follows: 1. Because of the variability of the sacral tumor, we cannot define the most common tumor. 2. There is difficult in early diagnosis of the tumor, because the symptoms of tumor are similar to that of lumbar disc herniation and the radiologic findings are subtle. 3. CT and MRI are very effective methods to detect the tumor in the sacrum. 4. Curettage, excision, resection, sacrectomy and internal fixation were done according to the kinds of tumors and the amount of bony destruction.

Seventy-five patients with tumors of the head and neck treated with either radiation therapy alone or combined with surgery or chemotherapy were studied prospectively to evaluate the effects of radiation therapy to the neck on thyroid gland between September 1986 and October 1992. All patients were serially monitored for thyroid function tests before and after radiation therapy. Radiation dose to the thyroid gland ranged from 35 to 60 Gy with a median dose of 50 Gy. Median follow-up time was 30 months with a range of 11 to 85 months. The incidence of thyroid dysfunction was 40%; forty-five patients (60%) euthyroid, 2 patients (3%) clinical hypothyroidism, 27 patients (36%) subclinical hypothyroidism and 1 patient (1%) hyperthyroidism. No thyroid nodules or thyroid cancer were detected in any patients. Thyroid dysfunction appeared earlier in patients who underwent surgery than in those patients treated with radiation therapy alone or combination of chemotherapy and radiation therapy (p=0.0013). By multivariate analysis, risk factors that significantly influenced a higher incidence of thyroid dysfunction were female sex (p=0.0293) and combination of total larygectomy and radiation therapy (p=0.0045). In conclusion, evaluation of thyroid function before and after radiation therapy with periodic thyroid function tests are recommended to detect thyroid dysfunction in time and thyroid hormone replacement therapy is recommended whenever thyroid dysfunction develops.

We encountered a case of neonatal altoimmune thrombocytopenia(NAIT) due to anti-HLA-B7+B60+B61. Bilateral cephal hematoma and umbilical hematoma were noted at the time of birth. Purpura developed at the third day. Platelet count was 110,000 at birth and decreased to 66,000/micro liter at the day 4. Prothrombin time and partial prothrombin time were within normal limit. The mother's platelet count was 220,000/micro liter and she had no history of abnormal bleeding. Platelet antibody tests empolying mixed passive hemagglutination and immunofluorescence revealed that the mother's serum was reactive against the platelets from the father and the neonate, but was not reactive with her own platelets. Platelets from eight volunteer group 0 donors were tested with the mother's serum; seven were reactive and one was negative. The positive reactions were lost after chloroquine treatment of platelets. Antigen capture ELISA(ACE) and modified antigen capture ELISA employing monoclonal antibodies against platelet glycoproteins In, IIa, IIb, and IIIa were negative. Mother's serum was tested for lymphocytotoxicity against 49 donor ]ymphocytes and the specificity was found to be anti-HLA-B7+B60+B61. At the 9th day, one unit of platelet concentrate from the mother was transfused and the platelet count of the neonate rose up to 340,000/micro liter. The neonate was discharged at the day of sixteenth and the platelet count remained high thereafter.
