  • Stress is now recognized as a universal premorbid factor associated with many risk factors of various chronic diseases. Acute stress may induce an individual's adaptive response to environmental demands. However, chronic, excessive stress causes cumulative negative impacts on health outcomes through "allostatic load". Thus, monitoring the quantified levels of long-term stress mediators would provide a timely opportunity for prevention or earlier intervention of stressrelated chronic illnesses. Although either acute or chronic stress could be quantified through measurement of changes in physiological parameters such as heart rate, blood pressure, and levels of various metabolic hormones, it is still elusive to interpret whether the changes in circulating levels of stress mediators such as cortisol can reflect the acute, chronic, or diurnal variations. Both serum and salivary cortisol levels reveal acute changes at a single point in time, but the overall long-term systemic cortisol exposure is difficult to evaluate due to circadian variations and its protein-binding capacity. Scalp hair has a fairy predictable growth rate of approximately 1 cm/month, and the most 1 cm segment approximates the last month's cortisol production as the mean value. The analysis of cortisol in hair is a highly promising technique for the retrospective assessment of chronic stress. [BMB Reports 2015; 48(4): 209-216]

  • The use of sulfadoxine and pyrimethamine (SP) for treatment of vivax malaria is uncommon in most malarious areas, but Plasmodium vivax isolates are exposed to SP because of mixed infections with other Plasmodium species. As P. vivax is the most prevalent species of human malaria parasites in Iran, monitoring of resistance of the parasite against the drug is necessary. In the present study, 50 blood samples of symptomatic patients were collected from 4 separated geographical regions of south-east Iran. Point mutations at residues 57, 58, 61, and 117 were detected by the PCR-RFLP method. Polymorphism at positions 58R, 117N, and 117T of P. vivax dihydrofolate reductase (Pvdhfr) gene has been found in 12%, 34%, and 2% of isolates, respectively. Mutation at residues F57 and T61 was not detected. Five distinct haplotypes of the Pvdhfr gene were demonstrated. The 2 most prevalent haplotypes were F57S58T61S117 (62%) and F57S58T61N117 (24%). Haplotypes with 3 and 4 point mutations were not found. The present study suggested that P. vivax in Iran is under the pressure of SP and the sensitivity level of the parasite to SP is diminishing and this fact must be considered in development of malaria control programs.

  • Hyperadrenocorticism (HAC) is a common endocrinopathy among dogs that causes multisystemic signs. This study was conducted to evaluate cardiocirculatory, biochemical, and hemostatic parameters in dogs with HAC at diagnosis, in addition to verifying whether abnormal parameters could be controlled by initial treatment with trilostane. Fifteen dogs with HAC were assessed by systolic blood pressure measurement, electrocardiography, Doppler echocardiography, serum concentration of troponin I, and biochemical and hemostatic profile at diagnosis and after trilostane therapy. Unlike biochemical parameters, hemostatic and cardiocirculatory parameters were not significantly influenced by the onset of treatment. The authors believe that clinical treatment with trilostane for 3 to 4 months might not be sufficient for the stabilization of cardiocirculatory abnormalities such as hypertension. Therefore, dogs with HAC must receive cardiocirculatory monitoring at diagnosis and during drug treatment.

  • Williams syndrome is a rare congenital disorder with various physical abnormalities and characterized by facial, oral, and dental features. Individuals with Williams syndrome typically have eating disorders in the early childhood, which lead to prolonged night feeding. Prolonged night feeding is a risk factor for rampant dental caries. Williams syndrome is caused by the microdeletion of chromosome 7, resulting in elastin deficiency. Elastin is integral to cardiovascular health. Many patients with Williams syndrome have complex cardiovascular abnormalities that must be considered a part of dental management. Complications related to cardiovascular diseases may induce adverse effects such as dangerously elevated blood pressure. This may occur in patients during stressful dental treatment. In addition, characteristics of auditory hyperalgesia and anxiety disorders among patients with William syndrome, complicate receiving routine dental management. Therefore, dental treatment under sedation or general anesthesia may be preferable for patients with Williams syndrome; in particular, patients who are very uncooperative and/or needs extensive dental treatment. A thorough evaluation of each patient's physical condition is required before making decisions regarding dental treatment. Careful monitoring and preparation for emergencies are very important during and shortly after dental treatment under general anesthesia or sedation. Monitoring is critical until vital signs have stabilized and return to normal. A 28-month-old man diagnosed as having Williams syndrome, visited the Dental Hospital of ${\bigcirc}{\bigcirc}$ University for the management of rampant dental caries. We reported on the management of this patient who had peripheral pulmonic stenosis, and received dental treatment under general anesthesia. We also reviewed the characteristics of Williams syndrome and discussed considerations for dental treatment under general anesthesia.

  • Purpose: The purpose was to assess the usefulness of midazolam in patients undergoing minor oral surgery under conscious sedation. Materials and methods: Bispectral index was examined in 20 patients receiving oral minor surgery with conscious sedation supplemented with local anesthesia. All patients included were ASA I and had no contraindications to the study medications. The patients were escorted to the day surgery operation room where, before the commencement of the sedation and surgical procedures, routine monitoring was applied, including the noninvasive monitoring of arterial blood pressure, arterial oxygen saturation, and 3-lead electrocardiogram (Electrocardiogram). Bispectral index electrodes were applied on the frontotemporal region after cleansing the skin with alcohol. Bispectral index was calculated with the Electrocardiogram monitor (A-2000; Aspect Co.). Midazolam was then titrated (initially 3mg wait 2min and 2mg). Vital sign and Bispectral index checked every 5 minute until the end of the procedure. The results were then compared. Results: The Bispectral index index values throughout the sedation study period alter many level. The index was dropped at 5 minutes after administration, but raised at injection and odontomy procedure. During the operation, mean Bispectral index index was higher than conscious sedation index range($60{\sim}80$). The amnesic effect was shown 17 cases out of 20 cases(85%). Conclusion: Conscious sedation technique using midazolma is a safe and effective method of controlling behavior in oral and maxillofacial surgery.

  • Background: The management of hepatic injuries has changed dramatically during the past two decade after the technologic breakthroughs in radiologic imaging techniques. Recently, the non-operative management of blunt hepatic trauma has become the standard of care in hemodynamically stable patients. We reviewed our experience of the non-operative management of blunt hepatic trauma. And the purpose of this study was to examine the prognostic factors and indicators affecting the decision for treatment modality of emergent hepatic trauma. Methods: The medical records of 84 patients who were treated for blunt hepatic injury at Masan Samsung Hospital from January 2002 to December 2003. The patients were divided two groups, non-operative(Non-OP) and operative(OP), according to the treatment modality. The two groups were compares for age, sex, mechanism of injury, grade of liver injury scale, combined injury, systolic blood pressure, pulse rate, hemoglobin, hematocrit, WBC count, S-GOT, S-GPT, ALP, transfusion amount during initial 24 hours, amount of infused crystalloid fluid, length of ICU stay, length of ward care, morbidity and mortality. The grade of the liver injury were determined by using the organ injury scale(OSI). Results: Among the 84 patients, 46 cases(54.8%) were managed non-surgically, and 3 cases of Non-OP group were treated by transarterial embolization. Between the two groups, there were significant difference in age, injury grade, combined injury, hemoglobin, hematocrit, initial systolic blood pressure, amount of infused crystalloid fluid, amount of transfusion during the first 24 hours, and length of ICU care, morbidity and mortality.(p<0.05) The overall mortality rate was 8.3%, but 2.2% mortality in the non-operative group. Conclusion: Non-operative management may be considered as a first choice in hemodynamic stable patients with blunt liver trauma. The reliable indicators affecting the treatment modality of blunt hepatic trauma were systolic BP, Hb, Hct, amount of infused crystalloid fluid, amount of transfusion during the first 24 hours, liver injury grade and combined injury. Strict selection of treatment madality and aggresive monitoring with intensive care unit were more important.

  • Objectives: Masked hypertension is associated with metabolic risks and increased risk of cardiovascular disease. The purpose of this study was to identify the frequency of and risk factors of masked hypertension in Korean workers. Methods: The study was conducted among 121 employees at a hotel in Gyeongju, Korea, from December 2008 to February 2009. We measured blood pressure (BP) both in the clinic and using 24-hour ambulatory BP monitors for all subjects. Hypertension was defined independently by both methods, and subjects were classified into four groups: true normotension, masked hypertension, white coat hypertension, and sustained hypertension. Results: The frequency of masked hypertension in our study group was 25.6%. Compared with true normotension, the factors related to masked hypertension were male gender (odds ratio [OR], 10.7; 95% confidence interval [CI], 1.41 to 81.09), aging one year (OR, 0.88; 95% CI, 0.78 to 0.99), clinic BP 120-129 /80-84 mmHg (OR, 8.42; 95% CI, 1.51 to 46.82), clinic BP 130-139 / 85-89 mmHg (OR, 12.14; 95% CI, 1.80 to 81.85), smoking (OR, 5.51; 95% CI, 1.15 to 26.54), and increase of total cholesterol 1 mg / dL (OR, 1.05; 95% CI, 1.02 to 1.08). In males only, these factors were clinic BP 120-129/ 80-84 mmHg (OR, 15.07; 95% CI, 1.55 to 146.19), clinic BP 130-139/ 85-89 mmHg (OR, 17.16; 95% CI, 1.56 to 189.45), smoking (OR, 11.61; 95% CI, 1.52 to 88.62), and increase of total cholesterol 1 mg/dL (OR, 1.05; 95% CI, 1.01 to 1.09). Conclusions: The frequency of masked hypertension was high in our study sample. Detection and management of masked hypertension, a known strong predictor of cardiovascular risk, could improve prognosis for at-risk populations.
