Cerebral Venous Sinus Thrombosis (CVST) in children is rare and its cause is multifactorial. The clinical manifestations of CVST vary and may cause long-term neurological sequelae and even death on rare occasion. In this case, a 15 year old boy presented with severe headache and vomiting for 1 day. Brain MRI with venography revealed multiple lesions of CVST in superior sagittal sinus and the left transverse sinus. Anticoagulation therapy was performed for 3 months, which led to the complete resolution in superior sagittal sinus and partial resolution in left transverse sinus.

Background and Objectives: The aim of this study was to determine the clinical effectiveness of parotid gland (PG) massage for the prevention of PG dysfunction after administration of radioiodine (I-131) therapy for treatment of differentiated thyroid cancer (DTC). Materials and Methods: One hundred patients with DTC with planned high-dose I-131 therapy were enrolled in the clinical trial and randomized into two groups (massage and non-massage group). Serum amylase values were obtained before and 24 h after I-131 therapy, and salivary gland scintigraphy (SGS) were taken before and at eight months after the I-131 therapy. Additional SGS (addSGS) were taken when the patients complained symptoms related to salivary gland dysfunction. Questionnaire surveys were performed before and until two years after I-131 therapy. Results Ninety-five of 100 patients finished the study protocol. Changes in survey scores tended to be higher in the non-massage group. The non-massage group had more severe symptoms related to salivary gland dysfunction. Among 32 patients who underwent addSGS, 27 had normal 8-month SGS. Of these 27 patients, 18 (66.7%) had salivary gland dysfunction on the addSGS. Amylase values were significantly increased in patients with normal 8-month SGS but abnormal addSGS, as compared to patients who were normal on both 8-month SGS and addSGS (p=0.046). Amylase difference values were a significant predictor of abnormal addSGS (p=0.002). Conclusion: PG massage reduced symptoms related to salivary gland dysfunction. The PG massage may be helpful in preventing damage to salivary glands caused by I-131 therapy.

Severe symptomatic hyponatremia shows high mortality in association with cerebral edema and central nervous system dysfunction. Postoperative hyponatremia is usually attributed to administration of hypotonic fluids while antidiuretic hormone is acting. However, we experienced a severe symptomatic hyponatremia in spite of infusion of lactated Ringer's solution perioperatively in a case of 4-year-old girl's tonsillectomy. Inappropriate secretion of ADH caused by pain, stress, anxiety, nausea, vomiting. Paralytic ileus developed several hours after surgery, severe hyponatremia (Na 119 mmol/L) with convulsion notified. After prompt infusion of sodium supplement and fluid restriction, the patient recovered uneventfully.

OBJECTIVES: Nowadays most infants on exclusively breast feeding have vitamin D deficiency due to the increase of breast feeding. However, domestic research lacks appropriate materials. Therefore, we researched practical clinical aspects of vitamin D deficiency related to breast milk feeding for infants who have a high amount of alkaline phosphatase (> 500 IU/L). METHODS: The subjects of the study were 31 infants with high alkaline phosphatase level. We tested with 25-hydroxycholecalciferol (25-OHD3), parathyroid hormone, calcium, ionized calcium, phosphorus in their blood and with a wrist x-ray. Then, we divided them into two groups of breast feeding and formula feeding and compared the results. RESULTS: Eighteen infants (58%) out of 31 infants that have high alkaline phosphatase were vitamin D insufficiency or deficiency, and 16 (100%) breast feeding infants of them showed vitamin D deficiency or insufficiency. However, only 2 (13%) of 15 formula feeding infants were at insufficiency. There was a correlation between alkaline phosphatase and 25-OHD3 concentration in multiple regression analysis, but no correlation in other variables was found in group of breast milk feeding infants. There was neither correlation between vitamin D concentration and alkaline phosphatase nor other correlated variables in the group of formula milk feeding infants. CONCLUSIONS: In this study, there was a high probability of vitamin D deficiency in the breast feeding infants with a high alkaline phosphatase level. Therefore, it is considered to be worth utilizing alkaline phosphatase as a screening test for vitamin D deficiency or rickets for breast feeding infants.

In 1897, Poncet described polyarthritis in patients suffering from tuberculosis which was not caused by tuberculosis infection of the joints. Poncet's disease is characterized by a polyarthritis that occurs during the acute tuberculosis infection in which no mycobacterial involvement can be found or other known cause of polyarthritis detected. It is a different entity from tuberculous arthritis, which is usually monoarticular and is caused by direct tuberculous infection. It was little known for pathogenesis of Poncet's disease, but immunologic reaction was suggested. Poncet's disease is associated with an excellent prognosis with rapid resolution on commencing therapy and no sequelae. Therefore, recognition of Poncet's disease can be important. Poncet's disease remains a diagnosis of exclusion.Recently, we experienced one case of Poncet's disease which have characterized by the clinical manifestations, and report this case with a review of the literatures.

This study examined whether propofol and aminophylline affect the mobilization of intracellular calcium in human umbilical vein endothelial cells. Intracellular calcium was measured using laser scanning confocal microscopy. Cultured and serum-starved cells on round coverslips were incubated with propofol or aminophylline for 30 min, and then stimulated with lysophosphatidic acid, propofol and aminophylline. The results were expressed as relative fluorescence intensity and fold stimulation. Propofol decreased the concentration of intracellular calcium, whereas aminophylline caused increased mobilization of intracellular calcium in a concentration-dependent manner. Propofol suppressed the lysophosphatidic acid-induced mobilization of intracellular calcium in a concentration-dependent manner. Propofol further prevented the aminophylline-induced increase of intracellular calcium at clinically relevant concentrations. However, aminophylline reversed the inhibitory effect of propofol on the elevation of intracellular calcium by lysophosphatidic acid. Our results suggest that propofol and aminophylline antagonize each other on the mobilization of intracellular calcium in human umbilical vein endothelial cells at clinically relevant concentrations. Serious consideration should be given to how this interaction affects mobilization of intracellular calcium when these two drugs are used together.

BACKGROUND AND OBJECTIVES: The level of thyroid-stimulating hormone (TSH)-stimulated thyroglobulin (Tg) after thyroid hormone withdrawal (THW) is the most sensitive marker for detecting recurrence of differentiated thyroid cancer (DTC). In DTC, Tg production is regulated by TSH; however, TSH values after THW are never identical, even in the same patient. The objective of this study was to evaluate the influence of TSH on Tg levels after THW. MATERIALS AND METHODS: TSH and Tg concentrations were measured twice at 2 and 3 weeks after THW in 309 patients with DTC. TSH and Tg levels at these time points were compared. The percent change in TSH (ΔTSH) and change in Tg level (%ΔTg) from 2 to 3 weeks after THW were calculated, and Pearson's correlation coefficients were calculated to determine whether ΔTSH could affect %ΔTg. Tg cutoff value for diagnostic imaging was 2 ng/mL. RESULTS: The TSH and Tg values at 3 weeks were significantly higher than those at 2 weeks after THW. Tg values increased significantly to >2 ng/mL after 1 week in 38.5% of the patients with Tg values of 0.2-2 ng/mL at 2 weeks after THW. In patients with Tg values ≥2 ng/mL at 2 weeks after THW, Tg values increased significantly after an additional week of THW. ΔTSH correlated significantly with %ΔTg. CONCLUSION: TSH values differed according to time after THW, and Tg values differed significantly according to TSH values. Therefore, TSH values should be considered carefully when interpreting the meaning of Tg levels in patients with DTC.

PURPOSE: In this study, doctors were surveyed with a questionnaire to determine whether they performed simultaneous vaccination and whether there were any concerns about safety or anxiety. The purpose of this study was to determine any problems associated with doctors readily performing simultaneous vaccination. METHODS: A trained surveyor visited 241 doctors from every institution registered with the National Immunization Program (NIP) located within six districts (gu) in the City of Busan (Dongnae-gu, Geumjeong-gu, Yeonje-gu, Suyeong-gu, Busanjin-gu, Haeundae-gu); a total of 155 (64%) valid responses were obtained. RESULTS: Of the 155 respondents, 144 (93%) were already performing simultaneous immunizations and 141 (91%) had a positive view of the practice. However, among the 144 doctors performing simultaneous immunizations, 67 (47%) were not confident about its safety; side effects were seen after simultaneous immunization by 86 doctors, 35 (41%) of whom believed that the frequency or possibility of side effects in simultaneous immunizations was higher than that in sequential immunizations. CONCLUSIONS: The use of simultaneous immunization is expanding quickly. However, among the doctors performing simultaneous immunizations, a high percentage had concerns over its unproven safety and potential side effects, indicating the need for academic societies or government institutions to present evidence to address such concerns.

Rett syndrome (RTT) is an X-linked dominant neurodevelopmental disorder affecting 1 per 10,000- 15,000 female births worldwide. The disease-causing gene has been identified as MECP2 (methyl- CpG-binding protein 2). In this study, we performed diagnostic mutational analysis of the MECP2 gene in RTT patients. Four exons and a putative promoter of the MECP2 gene were analyzed from the peripheral blood of 43 Korean patients with Rett syndrome by PCR-RFLP and direct sequencing. Mutations were detected in the MECP2 gene in approximately 60.5% of patients (26 cases/43 cases). The mutations consisted of 14 different types, including 9 missense mutations, 4 nonsense mutations and 1 frameshift mutation. Of these, three mutations (G161E, T311M, p385fsX409) were newly identified and were determined to be disease-causing mutations by PCR- RFLP and direct sequencing analysis. Most of the mutations were located within MBD (42.3%) and TRD (50%). T158M, R270X, and R306C mutations were identified at a high frequency. Additionally, an intronic SNP (IVS3+23C>G) was newly identified in three of the patients. IVS3+23C>G may be a disease-related and Korea-specific SNP for RTT. L100V and A201V are apparently disease-causing mutations in Korean RTT, contrary to previous studies. Disease-causing mutations and polymorphisms are important tools for diagnosing RTT in Koreans. The experimental procedures used in this study should be considered for clinical molecular biologic diagnosis.
