Spontaneous remission(SR) of acute leukemia is an extremely rare event. The precise incidence of SR in acute myeloid leukemia(AML) could not be assessed accurately because the majority of patients usually received induction chemotherapy within a few days after diagnosis. The mechanisms of SR are still not completely understood; therefore, the study of them is expected to contribute to the treatment of acute leukemia. We report a case of AML with SR, observed in a 23-year-old male who experienced severe infection and transfusions, with a brief review of the literature.

Purpose: For college students, poor eating habits can cause problems with adult health. This study investigated the status of sweet food intake and the degree of stress in college students in the Seoul and Gyeonggi areas to provide a basis for nutrition education by analyzing the relationship between stress and sugar intake. Methods: The subjects were 760 college students, and the survey was conducted using a questionnaire. Statistical analysis for collected data was performed using SPSS (version 21.0). Results: The stress score showed higher stress in female students. Females had more stress in their employment and study-related problems than males. For changes in food intake under stress, the intake was increased greatly in females than in males. For food preference changes before and after stress, males preferred more spicy foods and less salty foods after stress. After stress, females significantly preferred sweeter and spicier foods and less salty, sour, and bitter foods. The intake of sweet foods by stress factors showed that the intake of snacks was higher under the condition of ‘worry, fatigue, and tension’, and the intake of beverages was increased significantly under the condition of ‘anger and aggression’. Conclusion Sweet foods were preferred under stress, and the amount of intake was increased. Education on food selection and nutrition information should be provided to prevent health problems that can be developed by the reckless intake of sweet foods. Active guidance is needed for college students to select the proper snacks instead of nutritionally insufficient foods to relieve stress.

BACKGROUND: As our population in Korea ages, more postoperative pulmonary complications (PPCs) have recently developed. There have been several studies about the predictive factors for PPC, but any consensus has not been established. In this study, we reappraised the predictive factors for PPC after general anesthesia in a population from Gyeong-ju, which was composed of elderly people. METHODS: We retrospectively investigated the incidence and predictive factors for PPC in 84 patients who underwent general anesthesia. We investigated gender, age, height, weight, BMI, smoking, underlying disease, underlying respiratory disease, malignancy, the laboratory findings (hemoglobin, albumin, arterial O2 saturation) and the pulmonary function tests of the patients. RESULTS: 84 patients were initially enrolled into the study, and PPC developed in 31 (36%) patients. The mean age of the enrolled patients was 66.515.1 years-old, so it shows the trend of an aging society. Three predictive factors were revealed that are independently associated with the PPC: site of operation (OR, 8.3), underlying disease (OR, 9.9) and serum albumin (OR, 4.0). CONCLUSIONS: Among the statistically meaningful predictive factors, underlying disease and operation site are well known from previous studies, but the albumin level<3.5 g/dL is also meaningful, which is higher than the previous reference level. It implies that the patient with a albumin level 3.0~3.5 g/dL can be classified into the high risk group. Therefore, we should recognize that it is necessary to apply more strict reference levels in an aging population to reduce the incidence of PPC.

From March, 1988 to August, 1989, the authors performed nasolacrimal duct reconstruction with Pyrex glass tube without bony perforation in 26 eyes of 25 patients who has chronic dacryocystitis with nasolacrinal duct obstruction. This method is implantation of permanent indwelling pyrex glasstube from base of the sac through the interosseous canal into the vault of inferior nasal meatus and there are several advantages in this method; The technique is more simple and less traumatic than other dacryocystorhinostomy, tear drainage inferioly prevents pooling of tear in inferior portion of lacrimal sac after surgery, normal anatomic relationships are retained and less postoperative care is required. The results were as follows: 1. Success was achieved in 24 of 26 cases including partial success. 2. Postoperative complications were developed that hypertrophic scar 2 cases, superficial punctate keratitis 1 case, wound infection 1 case, nasal bleeding 1 case.

Nerve sheath myxoma or neurothekeoma, a rare cutaneous neoplasm probably originating from the nerve sheath, is classified into three groups as classical, cellular, and mixed types based on cellularity, mucin content and growth patterns. Only two cases of nerve sheath myxoma have been reported in the Korean literatures. We report a case of nerve sheath myxoma occurring on the scalp of a 29 year-old woman. It was identified as the mixed type by histopathological, immunohistochemical and electronmicroscopic findings.

BACKGROUND: With the development of bioengineering techniques for noninvasive characterization of skin pathophysiology, the induction of irritant dermatitis by surfactants has been extensively studied. OBJECTIVE: We performed this study to compare the skin responses in terms of transepidermal water loss (TEWL) and erythema induced by benzalkonium chloride (BAC), a well-known non-corrosive irritant, in comparison with sodium lauryl sulfate (SLS), a representative corrosive irritant. METHOD: We applied 0.1, 0.2, 0.5, 1, and 2% solutions of BAC and SLS on volar forearm skin for 24 hours using a large Finn chamber with filter paper disc on 19 normal healthy subjects. TEWL and erythema index (E-index) were measured prior to testing, then at 30 minutes, one day, two days, three days, one week, and two weeks after the removal of the patches. RESULTS: TEWL values of BAC and SLS patch areas increased with concentration. However, BAC induced a significantly lower TEWL increase than SLS did at the corresponding concentrations. TEWL induced by BAC was highest at 30 minutes after the removal of the patch, whereas TEWL induced by SLS was highest at one day. TEWL values had recovered with the passage of time to baseline values at 2 weeks after removal of the patch at lower concentrations (0.1, 0.2, 0.5%) of SLS, but still showed significantly high TEWL values at 1% and 2% concentration SLS patch areas. TEWL values of BAC in 0.1, 0.2, 0.5 and 1% concentrations had recovered to the baseline values at 2 weeks after the removal of the patch, but not in 2% concentration BAC patch areas. E-indices of BAC and SLS increased with concentration in a similar reaction pattern. E-index induced by BAC was highest at 30 minutes after the removal of the patch, and E-index induced by SLS was highest at 30 minutes or 1 day after the removal of the patch. E-index of each concentration, except 2%, had recovered with the passage of time to baseline values on both BAC and SLS patch areas at 2 weeks, but E-indices of both 2% BAC and SLS did not recover at 2 weeks. CONCLUSION: Benzalkonium chloride showed much less damage to the skin barrier function compared to the corresponding concentration of SLS, whilst they showed a similar degree of erythema. Skin barrier function affected by the corrosive irritant SLS would need a more prolonged recovery time than skin barrier disruption by non-corrosive irritant BAC.

Inducible nitric oxide synthase (iNOS) expression of several organs on the lipopolysaccharides (LPS)-injected rats and on excisional wound was observed by immunohistochemical methods to investigate iNOS-positive cells during inflammation. iNOS expression was induced in response to LPS in the brain and these reactions were observed in the choroidal epithelium, ependymal cells and a few of nerve cells and fiber. A more intensive reaction of nerve cell and fiber was mainly observed in the corpus callosum and hypothalamus. Induction of iNOS of the lung was observed in alveolar macrophage, smooth muscle, pneumocytes and inflammatory cells infilterated in the alveolar septum. iNOS expression of the liver was detected in Kupffer cells, hepatocytes, bile duct and inflammatory cells of spotty necrosis. The cardiac muscle and endothelial cell of the heart showed positive iNOS expression. In the excisional wound, inflammatory cells including macrophages, neutrophil and fibrobast showed iNOS expression and mainly detected necrobiotic layer. Collectively, iNOS expression was induced in the several cell types during inflammatory process. So for better understanding the function of iNOS, more research should be done in relation to each cell type of organ.

OBJECTIVES: The aim of this study was to explore clinical factors or high-risk factors associated with occurrence of delirium tremens (DT) during acute alcohol withdrawal in inpatients with alcohol dependence. METHODS: This study included 164 inpatients seeking treatment for acute alcohol withdrawal in the detoxification unit. All subjects were evaluated prospectively for known risk factors for DT and their occurrence of DT. Correlations were determined between risk factors obtained at admission and development of DT. RESULTS: Among all subjects, 42 patients (25.6%) suffered from delirium tremens within seven days after admission. DT patients had more severe alcohol withdrawal symptoms, the presence of past DT, and higher levels of aspartate aminotransferas, alanine aminotransferase, gamma-glutamyl-transpeptidase, and homocysteine, compared with patients who did not suffer DTs. According to results of a multiple regression, occurrence of DT showed correlation with the following factors at admission: tremor, a past history of DT, higher homocysteine level, and nausea and vomiting. CONCLUSION: Development of DT showed correlation with symptoms of severe alcohol withdrawal, past history of DT, and higher homocysteine level. Among these, a severity of alcohol withdrawal symptoms and a history of DT are factors that can be easily evaluated on the day of admission in order to predict the potential for occurrence of DT.
