The vestibular system is a sensory motor system concerned with the sensation of linear or angular acceleration, eliciting several vestibular postural reflexes. This study was designed to figure out the functional relationship in vestibulocollic reflex. The electromyographic responses of the cervical muscles were observed during stimulation of the horizontal semicircular canal nerves. The sternomastoid muscle was inhibited by stimulation of the ipsilateral horizontal canal nerve and excited by stimulation of the contralateral horizontal canal nerve. The splenius capitis muscle was inhibited by stimulation of the ipsilateral horizontal canal nerve and excited by stimulation of the contralateral canal nerve. The semispinalis capitis revealed same pattern responses as splenius capitis or sternomastoid muscles to stimulation of the horizontal canal nerve. These experimental results indicate that the cervical extensor or flexor muscles respond in a uniform fashion to the stimulated horizontal canal nerve. And taken these results and other morphological study results together, the excitatory neural pathways from the vestibular nucleus in brain stem to cervical motoneurons are crossed to the opposite side but the inhibitory pathways from the nucleus to the cervical motoneurons are uncrossed.

OBJECTIVES: Type D personality was originally introduced to study the role of personality in predicting outcomes of heart disease. However, researches showed that other medical conditions are also affected by this personality. The purpose of this study was to evaluate the relationship between type D personality and somatic symptom complaints in depressive patients. METHODS: Eighty-two individuals diagnosed with depressive disorder were included. Type D personality was measured with DS14. Patient Health Questionnaire(PHQ) 9 and 15 were used to measure depression severity and somatization tendencies. For alexithymia, TAS-20 was used. Student T-test and linear regression analysis were performed. The best regression model was determined by stepwise variable selection. RESULTS: More than half of the subjects(56%) complained at least medium degree somatic symptoms according to PHQ-15 criteria. Two-thirds of the subjects were classified as Type D personality(63.4%). The mean PHQ-15 score of the Type D individuals was significantly higher than the remaining subjects(PHQ-15 mean=12.7, p=8.2x10-7). The best regression model included age, PHQ-9 score and NA subscale score as predictor variables. Among these, only the coefficients of age(p=1.5x10(-3)) and NA score(p=1.5x10(-7)) were found to be statistically significant. CONCLUSIONS: The result showed that Type D personality was one of the strong predictors of somatic complaints among depressive individuals. The finding that negative affectivity rather than social inhibition was more closely associated with somatization tendencies does not fully agree with the traditional explanation that inability to express negative emotion predispose the individuals to somatic symptoms. The finding that alexithymia was not shown to be a significant predictors also substantiated this discrepancy. However, it might be possible that the high correlation between NA and SI subscore(r=0.65) and between NA and TAS-20 score(r=0.44) hid the additional effects of social inhibition and alexithymia. Further research with a larger sample would be needed to investigate the effects of the latter two components over and above the effect of negative affectivity on the somatic complaints in depressive patients.

BACKGROUND: This study aimed to identify the effects of a multifaceted needlestick injury (NSI) prevention program on changes in knowledge about bloodborne infectious diseases and postexposure coping, attitudes toward postexposure reporting, preventive measures, the number of NSIs, and postexposure reporting pre- and post-intervention among nurses. METHODS: A total of 429 and 420 nurses participated in the pre- and post-intervention periods, respectively. The intervention was performed from April to September 2007, comprising NSI guideline education, the use of containers with enhanced engineering, and the supply of safety devices. RESULTS: The average score of knowledge about bloodborne infectious diseases increased significantly from 8.3 to 8.9 out of 14 points (P<0.001), but the change in score of knowledge about postexposure coping was insignificant. The average score of attitude toward postexposure reporting increased significantly from 8.9 to 9.6 out of 12 points (P<0.001). Preventive measures such as "gloves are provided whenever needed" (P<0.001), "use one-hand technique" (P<0.001), and "needle containers are provided whenever needed" (P=0.031) increased significantly. The number of NSIs decreased by 40.4%, and the postexposure reporting rate increased by 552.8%. CONCLUSION: The multifaceted NSI prevention program positively affected knowledge about infectious diseases and postexposure coping, attitudes toward postexposure reporting, preventive measures, the number of NSIs, and postexposure reporting after intervention. Therefore, we recommend that this program be applied to various healthcare workers in hospitals.

This report describes the pathologic features of 17 cases of Castleman's disease, examined at the Department of Pathology, Seoul National University Hospital during a period from 1973 to 1989. The lesions in 12 cases were hyaline-vascular type and the remainders plasma cell type. The pathologic features favoring the plasma cell type over the hyaline vascular type included a sufficient number to large-sized follicles. However, a histologic overlapping between two types was present. In the hyaline vascular type the age of the patients ranged from 7 to 76 years and they appeared to be no particular sex predominence. The majority of the lesions occurred in the neck and within the chest. Almost all cases presented with a solitary mass except three cases. Neither conventional symptoms nor systemic manifestations were associated. The plasma cell type was characterized by presentation of constitutional symptoms, involvement of intra abdominal and inguinal lymphnodes, in association with unusual clinicopathologic features including IgA nephropathy, diabetes mellitus, systemic progressive sclerosis, peripheral neuropathy, and anemia. Immunohistochemical study was performed in three cases of the plasma cell type. Two cases revealed poly-clonal plasma cell infiltration. In a patient with IgA nephropathy, however, serum IgA was increase and a strong immunoreactivity to IgA heavy chain was found. Another case, associated with systemic progressive sclerosis and neuropathy, revealed monoclonal plasma cell infiltration (IgG and lambda light chain). The above results support a possibility that in some of the plasma cell type an altered immune mechanism is involved in its pathogenesis.

PURPOSE: This paper reports the results of a massage therapy on transcutaneous bilirubin (TcB) in the forehead and inguinal regions, feeding intake, urine amount, and defecation frequency for neonates with jaundice who are receiving phototherapy. METHODS: A non-equivalent control group, pre-post, quasi-experimental design was used. Participants were 33 neonates with jaundice admitted for phototherapy and were randomly assigned to one of two groups—an experimental group (n=16), which received 3 days of routine plus 15 minutes of massage three times a day, and a control group (n=17), which received the routine care only. Data were analyzed using χ²-test and Mann-Whitney U test with SPSS 21.0 Win program. RESULTS: On the second day of hospitalization, the experimental group showed significantly lower TcB in the inguinal region (Z=−2.12, p=0.017); on the third day, the experimental group showed significantly lower TcB in the inguinal region (Z=−2.31, p=0.011) and higher defecation frequency (Z=−2.22, p=0.013) compared with the control group. CONCLUSIONS: The study findings suggest that massage for jaundice neonates receiving phototherapy is an effective intervention to reduce TcB in the inguinal region and to increase defecation frequency.

Modern medical oncology has introduced various anti-cancer drugs since the World War I and II. Unlike for the solid tumors, hematological malignancies had been documented some limitations for curing it with chemotherapeutic agents only. In 1960, Dr. Nowell and Dr. Hungerford had discovered elongated chromosome (Philadelphia chromosome) which has documented as a product of translocation between 9th and 22nd chromosome in the patients with chronic myeloid leukemia. In 1970s, immunochemistry technique using monoclonal antibody has spread world widely and from 1990s, flow cytometry method has been available. In appreciation of these evolutions in basic science, the treatment strategy ofhematological malignancies has changed from the chemotherapeutic agents to targeted agents. Among the targeted agents, some drugs are newly developed and others are recreated as anti-cancer drugs after long-time of discard because of their toxicities or teratogenic effects. Nowadays, we are in the middle of flood of targeted agents, for example, tyrosinekinase inhibitors, epidermal growth factor receptor blockers, farnesyl transferase inhibitors, histone deacetylase inhibitors, and etc. In 21st century, the optimal treatment of hematological malignancies should follow a tailor- made strategy according to the patient and disease itself. In the present article, some representative agents will be introduced in accordance with target diseases.

BACKGROUND: Periungual warts are a therapeutic challenge. Many studies have revealed that intralesional interferon α-2b therapy and pulsed dye laser therapy have numerous advantages over other modalities of theratment. OBJECTIVE: The purpose of this study was to determine if combination therapy with intralesional interferon α-2b and pulsed dye laser might offer an effective treatment for periungual warts. METHODS: Thirty-three patients were randomly assigned to one of three study groups. In group A, the patients received both intralesional interferon α-2b treatment and pulsed dye laser(PDL) therapy (n=13). Group B patients were treated wit intralesional interferon α-2b alone (n=10) and group C was done with PDL therapy only (n=10). RESULTS: The clearance rate was 92.3% for the patients treated with the combination therapy of intralesional interferon α-2b treatment and pulsed dye laser (PDL) therapy. It was 50% for the patients with the intralesional interferon α-2b treatment alone, and 0% for the group with the PDL therpy only. No significant side effects were observed. At 6 months after cessation of the therapy, total 2 cases (one from group A and the other from group B) were recurred. CONCLUSION: The combination therapy with intralesional interferon α-2b treatment and pulsed dye laser therapy was highly effective for the treatment of recalcitrant periungual warts.

Concurrent use of instrumentation has been shown to increase fusion rates and satisfactory results for surgical treatment of the lumbar stenosis. The objectives of the present study were to evaluate clinically and radiologically two groups of lumbar stenosis who were surgically treated with pedicular screw fixation system and posterior lumbar interbody or posterolateral autogenous bone graft following complete posterior decompression. One group was degenerative type and the other group was spondylolisthetic type spinal stenosis. We analyzed the results of 39 cases of lumbar stenosis who underwent pedicular screw and rod fixation system and posterior lumbar interbody or posterolateral autogenous iliac bone fusion following complete posterior decompressive operation during the period from May 1988 to December 1992. There were 27cases of degenerative type and 12 cases of spondylolisthetic type lumbar stenosis. The were 25 women and 14 men. Their age was ranged 20 to 76 years old with an average of 51.7 years old. The follow up period was the interval from 18 months to 6 years with an average of 3.2 years. The radiologic union rate was average 94.9% and 96.3%(26cases) in degenerative spinal stenosis and 91.7%(11 cases) in spondylolisthetic spinal stenosis. The clinical success rate was average 92.3%(36 cases), 88.9%(24 cases) in degenerative spinal stenosis and 100%(12 cases) in spondylolisthetic spinal stenosis. The patients with spondylolytic spinal stenosis showed better result in their life than the patient with degenerative spinal stenosis.
