PURPOSE: Fever plays an important role in causing disturbances in fluid and electrolyte balance. Hyponatremia has been thought to enhance the susceptibility to febrile convulsions in childhood and to increase a risk of repeat convulsion during same febrile illness. I therefore carried out a study in attempt to investigate how high the serum sodium level is in children with febrile convulsions, and whether there is an association between the recurrence of febrile convulsions and hyponatremia METHODS: Blood samples for serum sodium measurement were taken from 136 children visited to the Seoul Red Cross Hospital due to an acute febrile convulsion during the period between 1994 and 1996(patient group). I also checked serum sodium in a group of age-matched controls(control group I: no fever, no convulsion, control group II: fever only, control group In non-febrile convulsions). The patient group was divided into two groups, recurrent and non-recurrent groups. The results were analyzed by Student's t-test. RESULTS: The mean serum sodium level(134.99+/-3.59mmol/L) was significantly lower as compared to all control groups(control group I : 137.92+/-2.19mmol/L, control group II : 137.49+/-2.94mmo1/L, control group III : 137.73+/-2.52mmo1/L, p<0.001). The mean serum sodium levels were not different between each other control groups(p>0.05). Thirty-two of the 136 children(23.5%) with a febrile convulsion developed a repeat convulsion. The mean serum sodium level in the group with repeat convulsions(133.00 +/-3.21mmo1/L) was significantly lower than the mean in the group without repeat convulsions(135.85+/-3.28 mmol/L) The risk of a repeat convulsion approaches 60% In cases with serum sodium levels of 130 mmol/L and gradually decreases to less than 10% in cases with serum sodium levels of 140mmo1/L. CONCLUSION: Hyponatremia may increase the susceptibility to the febrile convulsions. The lower the serum sodium level, the higher the probability of a repeat convulsion This may be of practical value in deciding whether to admit the child and in advising parents or carers of the risk of a repeat convulsion.

This study was performed to investigate the distribution and magnitude of stress at supporting tissue of abutment teeth and residual ridge tissue with remaining unilateral posterior teeth. Four types of removable partial dentures that included clasp retained removable partial denture, attachment retained removable partial denture, telescopic removable partial denture, and swing-lock partial denture were designed, and strain gauge was used for stress analysis. Each prosthesis was subjected to simulated vertical and oblique load. The following conclusions were drawn from this study. 1. The clasp retained removable partial denture generally distributed simulated vertical force more evenly to the supporting structure. 2. The stress at buccal side of 1st premolar was the lowest in swing-lock partial denture and that was highest in attchment retained removable partial denture. The stress at lingual side of 1st premolar was the lowest in telescopic partial denture. 3. In clasp retained removable partial denture, stress was lower at load site and ridge crest at midline, but it was higher at lst premolar area on vertical load. 4. In attachment removable partial denture, stresses at buccal side of 1st premolar, lingual side of 1st premolar on vertical load, and ridge crest at midline on oblique load were higher. 5. In telescopic removable partial denture, stress at lingual side of 1st premolar was the least in all removable partial dentures, but the stress at load site was higher. 6. In swing-lock removable partial denture, stress at buccal side of 1st premolar was the lowest, and stresses at load site and distal end of residual ridge crest were higher.

A prospective study of vitamin B6, B12, folate, and homocysteine levels was carried out in 7 kidney transplant(KT) recipients. The first sample for the basal level was drawn on the morning of the KT day before the start of cyclosporine injection. Thereafter, serial blood samples were taken every day until the serum creatinine level decreased below 1.5 mg/dl and then every 2 or 3days until discharge. The serum creatinine level decreased to below 1.5 mg/dl within 3days except for cases 4 and 6. The homocysteine levels decreased markedly in synchronisation with serum creatinine levels increased during the first 7days and then declined together with serum creatinine levels but went up again after a few days. The levels of B6, and vitamin B12 do not continue to decrease after the levels of serum creatinine have decreased to 1.5mg/dl, while homocysteine levels go up progressively. In conclusion, contrary to our expectation, the level of homocysteine rebounds a few days after KT following a transient decline. A deficiency of folic acid, vitamin B6 and vitamin B12 does not seem to cause hyperhomocysteinemia in KT recipients. It is necessary to pay attention to hyperhomocysteinemia in KT recipients, especially when the recipients have an atherosclerosis-related complication.

BACKGROUND: According to the 1992 version of ACLS guideline, adenosine is recommended as the first line drug far the treatment of paroxysmal supraventricular tachycardia(PSYT). But adenosine is not used frequently in our country, despite currency proven effect and safety. Therefore we tried to compare the efficacy and safety of adenosine with verapamil for the treatment far PSVT. MATERIALS AND METHODS: We prospectively reviewed charles of PSVT patients admitted to YongDong Severance Hospital from Jan. 1995 to Dec. 1996. These patients were randomly divided into two groups. The flat group was given 6mg of adenosine initially, and another 12mg was given within 5 minutes if fast dose failed. The other group was given 5mg of verapamil initially, and if failed, 10mg was given within 10 minutes. The results were analyzed by Chi-square test and student-t method. RESULTS: In converting PSVT to normal rhythm, adenosine and verapamil showed similar results and there was no difference between the two Groups in frequency of side elects, but serious arrhythmia such as ventricular fibrillation and ventricular tachycardia was not seen in the adenosine group. CONCLUSION: Adenosine not only showed comparable effect and safety, but also had shorter action time than verapamil. Therefore we recommand adenosine, as a safe and effective fort line drug for PSVT.
