Diabetes Mellitus (DM) is a syndrome accompanied with the abnormal secretion or function of insulin, a hormone that plays a vital role in controlling the blood glucose level (BGL). Type 1and 2 DM are most common form and the prevalence of the latter is recently increasing. The aim of this article was to assess whether Type 2 DM could act as a predisposing risk factor on the pulpo-periapical pathogenesis. Previous literature on the pathologic changes of blood vessels in DM was thoroughly reviewed. Furthermore, a histopathologic analysis of artificially-induced periapical specimens obtained from Type 2 diabetic and DM-resistant rats was compared. Histopathologic results demonstrate that the size of periapical bone destruction was larger and the degree of pulpal inflammation was more severe in diabetic rats, indicating that Type 2 DM itself can be a predisposing risk factor that makes the host more susceptible to pulpal infection. The possible reasons may be that in diabetic state the lumen of pulpal blood vessels are thickened by atheromatous deposits, and microcirculation is hindered. The function of polymorphonuclear leukocyte is also impaired and the migration of immune cells is blocked, leading to increased chance of pulpal infection. Also, lack of collateral circulation of pulpal blood vessels makes the pulp more susceptible to infection. These decrease the regeneration capacity of pulpal cells or tissues, delaying the healing process. Therefore, when restorative treatment is needed in Type 2 DM patients, dentists should minimize irritation to the pulpal tissue un der control of BGL.

Ovarian remnant syndrome is a rare condition which develops when functional ovarian tissue is left in situ after intended bilateral oophorectomy. It produces clinically significant syndrome, namely chronic pelvic pain and dysmenorrhea. Although the true incidence of this syndrome is unknown, an apprant increase in incidence has been reported. We have experienced a case of ovarian remnant syndrome showing chronic pelvic pain and palpable abdominal mass after difficult gynecologic operation. So, we report this case with a brief review of literatures.

The effect of Pheniramine(Avil), a histaminergic-1 receptor blocking agent presently employed in treating various allergic diseases on pressor actions of norepinephring(NE) and tyramine (TR) was studied in the rabbit. Pheniramine, when given into a femoral vein with a dose(3mg/kg) enough to block H1-receptor, potentiated markedly the pressor responses of NE and TR. The pressor action of NE augmented by pheniramine was not affected by additional adminstration of debrisoquin (Drenergic neuron blocker) or phenelzine(monoamine oxidase inhibitor) or desipramine(U1-uptake blocker), or while potentiated by additional treatment with chlorisondamine(ganglionic blocker)or reserpine(catecholamine depleter). The hypertensive response of NE to phenelzine or desipramine was reinforced significantly by addition of pheniramine, but the response of NE in rabbits treated with reserpine or chlorisondamine or debrisoquin was not influenced by pheniramine-addition. Elevation of blood pressure to TR potentiated by pheniramine was attenuated significantly by reserpine treatment with chlorisondamine made the significant augmentation of pressor action to TR after pheniramine. Tyramine-induced response of blood pressure after pheniramine, but the response of blood pressure to TR caused by phenelzine or desipramine was enhanced markedly by pheniramine-treatment. From the above experimental results, it is thought that the pressor effect of NE and TR potentiated by pheniramine is similar to that of debrisoquin, i.e. the sensitization of effector cell, and that central action of pheniramine can not ruled out.

OBJECTIVE: We report a retrospective investigation of the prognostic value of bcl-2 and bax expression, and Ki-67 proliferative index in 42 astrocytic tumors. METHODS: We classified the astrocytic tumors and reviewed the clinical information and survival time. The sections were taken from surgically resected paraffin-embedded tissue and performed immunohistochemical stains for bcl-2, bax and Ki-67. RESULTS: The immunohistochemical stain for bcl-2 revealed a positivity in only two(4.76%) among forty-two cases. The immunostain for bax was positive in 35 cases(83.3%). However, the correlation between bcl-2 & bax expression and age, sex, tumor location, size, and histologic grade was not found. By Kaplan-Meier analysis, bcl-2 & bax expression and survival time in astrocytic tumors was no significance in log rank test(p>0.05). There were prognostic values between Ki-67 LI and histologic grade and between Ki-67 LI and survival time, respectively(p<0.05). CONCLUSION: Bcl-2 and bax are not significant, whereas Ki-67 LI is suggested as a significant prognostic factor, associated with histologic grade and survival time of astrocytic tumors.

Purpose: A suboptimal nutritional status is often observed among hospitalized patients across all medical/surgical specialties. The objective of the present study was to (1) analyze the prevalence of malnutrition in severe trauma patients and (2) evaluate the relationship between malnutrition and select clinical outcomes. Materials and Methods: This retrospective study was conducted between October 2015 and March 2017 at the Pusan National University Hospital Trauma Center. Of a total of 3,560 patients, 945 were enrolled in this study. Patients were checked for malnutrition using a nutrition assessment tool by the hospital nutrition support team. The parameters assessed included serum albumin, the ratio of actual body weight to ideal body weight (%), total lymphocyte count, appetite, and gastrointestinal problems. Clinical outcomes under consideration included 1) mortality, 2) length of hospitalization, and 3) length of stay in the intensive care unit (ICU). Results: The total prevalence of malnutrition in hospitalized trauma patients was 55.0% (n=520). Malnutrition risk was the independent prognostic factor of mortality in severe trauma patients (adjusted odds ratio [OR]=3.440;95% confidence interval [CI]=1.401~8.447, P=0.007). Risk factors of malnutrition were age over 65 years (adjusted OR=2.393; 95% CI=1.699~3.370, P<0.001), injury severity score (adjusted OR=1.034, 95% CI=1.012~1.056, P=0.002), length of hospitalization (adjusted OR=1.104; 95% CI=1.007~1.020, P<0.001), and length of stay in the ICU (adjusted OR=1.050; 95% CI=1.029~1.072, P<0.001). Conclusion Malnutrition is widespread in hospitalized patients with severe trauma and results in suboptimal clinical outcomes. Thus, patients at high risk of malnutrition should be monitored carefully during hospitalization.

PURPOSE: The purpose of this study was to investigate the effect of the development and application of the new nurses' core skill program on the clinical skill, confidence, knowledge and performance of new nurses. METHODS: This study was a nonequivalent control group post-test design on 46 new nurses with 3 to 6 months work experience in a general hospital. Data were collected from August 2015 to August 2016. A training program of core fundamental nursing skills was applied on 23 new nurses from 2016 in the experiment group, and an existing training method was applied on 23 new nurses from 2015 in the comparison group. The collected data were analyzed using SPSS/WIN 23.0. RESULTS: The experimental group (89±4.29) showed higher score in practical skill assessment compared to the control group (85.09±3.99) and showed a statistically significant difference (p<001). CONCLUSION: A training program of core fundamental nursing skills for new nurses proved effective in improving practical skills. Further research on the development of a systemic training program that can improve clinical nursing knowledge and work ability for new nurses according to the extended enforcement of a Nursing Care Integrated Service ward is needed.

BACKGROUND: Spinal anesthesia for cesarean section is widely used technique for rapid induction, high success rate and excellent intraoperative and postoperative analgesia. Potentiating the effect of intrathecal local anesthetics by addition of opioid for cesarean section is well known. In this study, we compared the clinical effects when different doses of fentanyl were combined with intrathecal hyperbaric bupivacaine. METHODS: Ninety six healthy term parturients were randomly divided into four groups: Group C (control), : Group F10 (fentanyl 10 microg), : Group F15 (fentanyl 15 microg), F: Group F20 (fentanyl 20 microg). In every group, 0.5% heavy bupivacaine was added according to the adjusted dose regimen. We observed the maximal level of the sensory block and motor block, the quality of intraoperative analgesia, the duration of effective analgesia and the side effects. RESULTS: There were no significant differences between four groups in maximal level and recovery rate of sensory and motor block. Quality of intraopertive analgesia and muscle relaxation was increasing by increasing dosage of intrathecal opioids. Duration of effective analgesia was significantly prolonged in Group F15 and F20 than Group C and F10, but there were no differences between Group F15 and F20. And the frequencies of side effects such as hypotension, max sedation level were increasing by increasing dosage of intrathecal opioids. The Apgar scores were normal, and there were no differences between the four groups. CONCLUSIONS: The addition of fentanyl 15 microg for spinal anesthesia provides adequate intraoperative analgesia and good postoperative analgesia without significant adverse effects.
