The authors describe three patients of syringomyelia associated with posterior fossa tumor. The lesions were diagnosed by magnetic resonance imaging. Total removal of tumor without decompression of foramen magnum was done and regression of syringomyelia and improvement of symptoms were demonstrated. It is suggested that the blockage of cerebrospinal fluid flow at the foramen magnum by tonsilar herniation may play an important role in syrinx formation.

Background: Transfusions in pediatrics need to be performed carefully because of various variables, such as the blood volume and immature immune system. As a result, adverse transfusion reactions may appear differently from adults. This study examined the frequency and types of adverse transfusion reactions in pediatric patients. Methods: From January 2018 to December 2021, this study was conducted on 58 children who requested red blood cells, platelets, and plasma blood components from Chungbuk National University Hospital. The frequency and types of adverse transfusion reactions were analyzed retrospectively by reviewing blood transfusion-related medical records and compared with previous studies. Results: Approximately 0.9% of total blood components were transfused into pediatric patients; 1,179 units of blood components were transfused. The number of transfusions for red blood cells, platelets, and plasma was 383, 712, and 84 units, respectively. Among 58 patients, 23 adverse transfusion reactions were observed in 15 (25.9%) patients. Of these, 18 were febrile nonhemolytic transfusion reactions, and five were allergic transfusion reactions. Febrile nonhemolytic transfusion reactions occurred in 66.7% of cases with red blood cells, and allergic transfusion reactions occurred with platelets in 60% of cases. Conclusion This paper reported the incidence and types of adverse transfusion reactions in pediatric patients. This is expected to be more frequent in pediatric patients than adults, but most of them were relieved by supportive treatment because the symptoms were mild. As the awareness of hemovigilance is still low, it is essential to recognize and deal with adverse transfusion reactions through continuous education.

A 55-year-old male was admitted to emergency department with a hypoglycemic shock of unknown origin. He was presented with tonic seizure activity after admission. Initial diagnostic procedure could exclude diabetes mellitus, drug side effects, and exogenous insulin application. Detailed evaluation of the patient's history revealed that the patient had experienced repeated hypoglycemic episodes for 2 years. He was diagnosed with hypothyroidism six years ago. Initial laboratory investigations revealed hypoglycemia, hyponatremia, and low plasma cortisol level (0.18 microg/dL). Sellar magnetic resonance imaging showed empty sella. Replacement therapy with hydrocortisone resulted in the improvement of clinical symptoms. Combined pituitary stimulation test with exception of hypoglycemia induced growth hormone and cortisol stimulation test was performed. The response of thyroid stimulating hormone, prolactin, follicle-stimulating hormone, and luteinizing hormone was normal. We report the case of empty sella syndrome associated with hypoglycemic shock due to with multiple anterior pituitary hormone deficiencies.

OBJECTIVE: Despite several limitations, the Trauma Injury Severity Score (TRISS) is normally used to evaluate trauma systems. The aim of this study was to evaluate the preventable trauma death rate using the TRISS method in severe trauma patients with traumatic brain injury using our emergency department data. METHODS: The use of the TRISS formula has been suggested to consider definitively preventable death (DP); the deaths occurred with a probability of survival (Ps) higher than 0.50 and possible preventable death (PP); the deaths occurred with a Ps between 0.50 and 0.25. Deaths in patients with a calculated Ps of less than 0.25 is considered as no-preventable death (NP). A retrospective case review of deaths attributed to mechanical trauma occurring between January 1, 2011 and December 31, 2011 was conducted. RESULTS: A total of 565 consecutive severe trauma patients with ISS>15 or Revised Trauma Score<7 were admitted in our institute. We excluded a total of 24 patients from our analysis : 22 patients younger than 15 years, and 2 patients with burned injury. Of these, 221 patients with head injury were analyzed in the final study. One hundred eighty-two patients were in DP, 13 in PP and 24 in NP. The calculated predicted mortality rates were 11.13%, 59.04%, and 90.09%. The actual mortality rates were 12.64%, 61.547%, and 91.67%, respectively. CONCLUSION: Although it needs to make some improvements, the present study showed that TRISS performed well in predicting survival of traumatic brain injured patients. Also, TRISS is relatively exact and acceptable compared with actual data, as a simple and time-saving method.

Purpose: We aimed to evaluate the usefulness and safety of high-flow nasal cannula (HFNC) oxygen therapy in children with complex chronic diseases (CCD) with impending respiratory failure in the general ward. Methods: Medical records of subjects with HFNC oxygen use in the general ward at a Korean tertiary children’s hospital were reviewed. Children with CCD and impending respiratory failure were included. treatment success was defined as successful weaning from HFNC oxygen support and treatment failure as weaning failure that led to higher level of respiratory support such as invasive ventilation or noninvasive positive pressure ventilation. Results: Fifty cases were included. Thirty-five cases (70%) were weaned off HFNC oxygen successfully, 15 cases (30%) failed. At the time of HFNC oxygen administration, the treatment failure group showed higher heart rate (P = 0.043), carbon dioxide partial pressure (P = 0.002), and initial inspired oxygen fraction (P = 0.007). Within 72 hours of initial treatment, 20% of patients in the treatmentsuccess group were weaned off the HFNC oxygen and half in the treatment-failure group required invasive ventilation. One case experienced complication. Conclusion HFNC oxygen is safe and effective for respiratory support in the general ward to avoid invasive mechanical ventilation in children with CCD and impending respiratory failure.

OBJECTIVE: Investigation of initial 51 cases of single port access (SPA) laparoscopic surgery for large adnexal tumors and evaluation of safety and feasibility of the surgical technique. METHODS: We retrospectively reviewed the medical records of the first 51 patients who received SPA laparoscopic surgery for large adnexal tumors greater than 10 cm, from July 2010 to February 2015. RESULTS: SPA adnexal surgeries were successfully completed in 51 patients (100%). The mean age, body mass index of the patients were 43.1 years and 22.83 kg/m², respectively. The median operative time, median blood loss were 73.5 (range, 20 to 185) minutes, 54 (range, 5 to 500) mL, and the median tumor diameter was 13.6 (range, 10 to 30) cm. The procedures included bilateral salpingo-oophorectomy (n=18, 36.0%), unilateral salpingo-oophorectomy (n=14, 27.45%), and paratubal cystectomy (n=1, 1.96%). There were no cases of malignancy and none were insertion of additional ports or conversion to laparotomy. The cases with intraoperative spillage were 3 (5.88%) and benign cystic tumors. No other intraoperative and postoperative complications were observed during hospital days and 6-weeks follow-up period after discharge. CONCLUSION: Our results suggest that SPA laparoscopic surgery for large adnexal tumors may be a safe and feasible alternative to conventional laparoscopic surgery.

BACKGROUND/AIMS: A self-report questionnaire is frequently used to measure symptoms reliably and to distinguish patients with functional gastrointestinal disorders (FGIDs) from those with other conditions. We produced and validated a cross-cultural adaptation of the Rome III questionnaire for diagnosis of FGIDs in Korea. METHODS: The Korean version of the Rome III (Rome III-K) questionnaire was developed through structural translational processes. Subsequently, reliability was measured by a test-retest procedure. Convergent validity was evaluated by comparing self-reported questionnaire data with the subsequent completion of the questionnaire by the physician based on an interview and with the clinical diagnosis. Concurrent validation using the validated Korean version of the Short Form-36 Health Survey (SF-36) was adopted to demonstrate discriminant validity. RESULTS: A total of 306 subjects were studied. Test-retest reliability was good, with a median Cronbach's alpha value of 0.83 (range, 0.71-0.97). The degree of agreement between patient-administered and physician-administered questionnaires to diagnose FGIDs was excellent; the kappa index was 0.949 for irritable bowel syndrome, 0.883 for functional dyspepsia and 0.927 for functional heartburn. The physician's clinical diagnosis of functional dyspepsia showed the most marked discrepancy with that based on the self-administered questionnaire. Almost all SF-36 domains were impaired in participants diagnosed with one of these FGIDs according to the Rome III-K. CONCLUSIONS: We developed the Rome III-K questionnaire though structural translational processes, and it revealed good test-retest reliability and satisfactory construct validity. These results suggest that this instrument will be useful for clinical and research assessments in the Korean population.

OBJECTIVE: The incidence of subarachnoid hemorrhage (SAH) worldwide varies considerably. In spite of many reports about the incidence of SAH, there has been no report about the incidence of SAH on the basis of the Korean population. The purpose of this hospital-based study was to assess the actual incidence rates of aneurysmal SAH in Gwangju city and Jeollanamdo province. METHODS: All cases of SAH confirmed by computerized tomography (CT) between January 2007 and December 2007 were selected for analysis. For the data collection, three major training hospital and ten general hospitals working the CT in Gwangju city and four major general hospitals in Jeollanamdo province participate in this study. RESULTS: According to the official census of Korea, the population was 1,413,444 in Gwangju city and 1,929,836 in Jeollanamdo province in 2007. There were 163 patients in Gwangju city and 266 patients in Jeollanamdo province confirmed SAH by CT in 2007. The crude and the age- and sex-adjusted annual incidence rates per 100,000 population for all ages in Gwangju city were 11.5 and 12.4 for aneurysmal SAH and in Jeollanamdo province were 13.8 and 10.8. The incidence was higher in women and increased with age. The gender distribution varied with age. At young ages, the incidence was higher in men while after the age of 40 years, the incidence was higher in women. CONCLUSION: In the present study, the age- and sex-adjusted annual incidence rates is 11.8 in Gwangju city and Jeollanamdo province. The incidence was higher in women and increased with age.

BACKGROUND: Malassezia yeasts are lipophilic fungi that are found in 75~80% of healthy adults. Recently, various molecular biological techniques are being preferred to identify and classify the Malassezia yeasts. Pyrosequencing is a real-time DNA sequencing technique. This technology has the potential advantage of accuracy, ease-of-use, high flexibility and is now emerging as a popular platform for microbial typing. OBJECTIVE: We sought to implement novel molecular biology technique, namely pyrosequencing method in identifying and classifying Malassezia yeasts, and assess its clinical applicability. METHODS: We obtained ribosomal RNA sequences of 11 Malassezia standard strains from NCBI database. Primers for the initial PCR amplification of the target region (ITS2) and sequencing primers within the regions amplified by the PCR primers were designed using Pyrosequencing Assay Design Software (Biotage AB, Uppsala, Sweden). We obtained PCR amplifying fragments of genomic DNA isolated from the Malassezia yeasts. And pyrosequence reactions were performed using reagents provided with the PSQ 96 Sample Preparation kit. RESULTS: In the PCR analysis, all of 11 standard strains are shown at the 130 bp levels. In the pyrosequencing analysis, M. obtusa and M. furfur sequences were corresponded among 11 Malassezia standard strains. But, in 4 cases, Malassezia strains mismatched with expected Malassezia strain and in rest of 5 Malassezia strains, pyrosequencing was failed. CONCLUSION: As evidenced above, pyrosequencing analysis could provide a sensitive and rapid identification system for Malassezia species. But it still has many limitation to be applied to epidemiological surveys and clinical practice.
