PURPOSE: Transcranial electromagnetic stimulation(TMS) is a noninvasive method which stimulates the central nervous system through pulsed magnetic fields without direct effect on the neurons. Although the neurobiologic mechanisms of magnetic stimulation are unknown, the effects on the brain are variable according to the diverse stimulation protocols. This study aims to observe the effect of the magnetic stimulation with two different stimulation methods on the cultured hippocampal slices. METHODS: We obtained brains from 8-days-old Spague-Dawley rats and dissected the hippocampal tissue under the microscope. Then we chopped the tissue into 450 micrometer thickness slices and cultured the hippocampal tissue by Stoppini's method. We divided the inserts, which contained five healthy cultured hippocampal slices respectively, into magnetic stimulation groups and a control group. To compare the different effects according to the frequency of magnetic stimulation, stimulation was done every three days from five days in vitro at 0.67 Hz in the low stimulation group and at 50 Hz in the high stimulation group. After N-methyl-D-aspartate exposure to the hippocampal slices at 14 days in vitro, magnetic stimulation was done every three days in one and was not done in another group. To evaluate the neuronal activity after magnetic stimulation, the NeuN/beta-actin ratio was calculated after western blotting in each group. RESULTS: The expression of NeuN in the magnetic stimulation group was stronger than that of the control group, especially in the high frequency stimulation group. After N-methyl-D-aspartate exposure to hippocampal slices, the expression of NeuN in the magnetic stimulation group was similar to that of the control group, whereas the expression in the magnetic non-stimulation group was lower than that of the control group. CONCLUSION: We suggest that magnetic stimulation increases the neuronal activity in cultured hippocamal slices, in proportion to the stimulating frequency, and has a neuroprotective effect on neuronal damage.

Hyponatremia which is a very common electrolyte abnormality in hospitalized patients is defined as a plasma sodium concentration less than 135 mEq/L. Hyponatremia is generally caused by intravascular volume depletion, excessive salt loss and hypotonic fluid overload. It also can be caused by intravascular osmotic agent. Although most cases are mild and asymptomatic, acute severe hyponatremia can cause severe neurologic symptoms, such as seizures and coma. We report a rare case of severe hyponatremia induced by radiographic contrast agent.

Nineteen highly pathogenic avian influenza (HPAI) H5N8 viruses were isolated from wild birds in the Donglim reservoir in Gochang, Jeonbuk province, Korea, which was first reported to be an outbreak site on January 17, 2014. Most genes from the nineteen viruses shared high nucleotide sequence identities (i.e., 99.7% to 100%). Phylogenetic analysis showed that these viruses were reassortants of the HPAI H5 subtype and the H4N2 strain and that their hemagglutinin clade was 2.3.4.4, which originated from Eastern China. The hemagglutinin protein contained Q222 and G224 at the receptor-binding site. Although the neuraminidase protein contained I314V and the matrix 2 protein contained an S31N substitution, other mutations resulting in oseltamivir and amantadine resistance were not detected. No substitutions associated with increased virulence and enhanced transmission in mammals were detected in the polymerase basic protein 2 (627E and 701D). Non-structural-1 was 237 amino acids long and had an ESEV motif with additional RGNKMAD amino acids in the C terminal region. These viruses caused deaths in the Baikal teal, which was unusual, and outbreaks occurred at the same time in both poultry and wild birds. These data are helpful for epidemiological understanding of HPAI and the design of prevention strategies.

PURPOSE: The goal of oncoplastic breast surgery is to restore the appearance of the breast and improve patient satisfaction. Thus, the assessment of cosmetic results and patient-reported outcomes (PROs) using appropriately constructed and validated instruments is essential. The aim of the present study was to assess the long-term objective cosmetic results and corresponding PROs after oncoplastic breast surgery. METHODS: Cosmetic results were assessed by the patients, a medical panel, and a computer program (BCCT.core). PROs were assessed using BREAST-Q, a questionnaire that measures the perception of patients having breast surgery. The cosmetic results and PROs were analyzed in patients who underwent quadrantectomy and partial breast reconstruction utilizing the latissimus dorsi flap. RESULTS: The mean duration of the follow-up period was 91.6 months (range, 33.3-171.0 months), and mean age of the patients was 51 years old (range, 33-72 years). The mean tumor size was 2.1 cm (range, 0.9-5.5 cm). There was fair agreement between the medical panel and BCCT.core score (K = 0.32, P < 0.001), and a statistically significant correlation between the BCCT.core score and medical panel cosmetic results was identified (r = 0.606, P < 0.001). A better BCCT.core result was related to a higher PRO of each BREAST-Q domain-satisfaction with breasts (R2 = 0.070, P = 0.039), satisfaction with outcome (R2 = 0.087, P = 0.021), psychosocial well-being (R2 = 0.085, P = 0.023), sexual well-being (R2 = 0.082, P = 0.029), and satisfaction with information (R2 = 0.064, P = 0.049). CONCLUSION: Our long-term results of oncoplastic surgery achieved a high level of patient satisfaction with good cosmetic results. The medical panel and BCCT.core results correlated well with the PROs of the patients using valid, reliable, and procedure-specific measures.
