Carcinoma of the uterine cervix is the most common malignant tumor in Korean women. It is well known that carcinogenesis is a multi-step event involoving the inactivation of tumor supressor genes, such as p53 gene and RB gene. The inactivation of the normal functions of the tumor-suppressor proteins pRB and p53 are important steps in human cervical carcinogenesis, either by mutation or from complex formation with the HPV E6 and E7 oncoproteins. The pRB protein regulates early cell cyle progression by controlling transit through the G1 phase of the cell cyle. The p53 tumor suppressor gene product also plays a role in cell cycle control by the transcriptional regulation of cyclin-CDK inhibitor. Cervical carcinoma is an excellent model for studying the stepwise progression of cell transformation because this is reflected morphologically by the increasing dysplasia of the squamous cells before it becomes and invasive squamous cell carcinoma. The aim of this study was to examine the expression of pRB and compared that with overexpression of p53 in a series of cervical lesions including normal tissuess, dysplasias, carcinoma in situ and carcinomas by immunohistochemical staining with monoclonal antibody to elucidate the role of these tumor suppressor genes. The result were as follows: 1. In normal cervical mucosa and CIN I , a few positively stained cells for pRB were seen in basal and parabasal layer. 2. An abnormality of pRB, loss of expression was seen in 23.8% of CIN III and in 10.8% of invasive carcinoma. 3. Overexpression of p53 was demonstrated in 14.3% of CIN III and in 59.5% of invasive carcinoma. 4. The immunoreactivity of p53 was significantly increased (p<0.05) in stage II, III than stage I , whereas downregulation of pRB and tumor stage was not correlated. 5. The immunoreactivity of p53 was significantly increased (p<0.05) in squamous cell carcinoma than in adenocarcinoma, adenosquamous carcinoma and CIN III. These result suggest that an alteration of pRB is more frequently implicated in CIN III than invasive carcinoma, whereas overexpression of p53 may be involevd in late progression of uterine cervical carcinoma.

This study was undertaken for the clinical analysis and evaluation on 121 patients with incompetent internal os of the cervix, who were admitted and treated with McDonald operation or Shirodkar operation at the Soonchounhyang Medical Center from January 1991 to December 1995. The results of this study were as follows : 1. The incidence of this IIOC was 1.1% of 11,116 cases of total delivery. 2. The mean age of IIOC was 31.7 years old. 3. The average number of gravida was 3.2. 4. The most common contributary factor was previous history of artificial abortion (51.2 %), and midtrimester abortion (17.4 %), cervical laceration due to previous vaginal delivery (8.3 %) etc. was followed. 5. The success rate of operation was 76 %, and the highest success rate (85.7 %) was reveald with period from 15th weeks to 16th weeks of gestation. 6. When cervical dilatation was abscent or small, the success rate of operation was high. 7. The factors of failed operation were preterm labor (58.7 %), PROM (34.5 %), and PIH, bleeding. 8. The delivery method after operation was vaginal delivery in 83 cases (68.6%) and cesarean section in 38 cases (31.4 %).

Evans myopathy is a type of malignant hyperthermia showing characteristic distribution of myopathic changes. We present two cases of Evans myopathy, father and his son in a family. Five members of this family expired during ane sthesia and surgery and two of these cases were reported as the malignant hyperthermia. The muscle pathology shows moth-eaten appearance with or without unstained cores in NADH-TR stain and its difference between the father and his son is suggestive of rather progressive myopathy than static one. s

Leigh syndrome (LS) is a genetically and clinically heterogeneous disorder caused by metabolic defects affecting lactate/pyruvate metabolism. The consequence of the metabolic defects are decreased amounts of APT and basic cell energy productions of the nervous system. In LS, several mutations have been reported in both the nuclear and the mitochondrial genome. Here, we report a 26-year-old woman clinically diagnosed with LS having characteristic brain MR and MRS abnormalities but without known definite pathogenetic mitochondrial DNA mutations.

In clinical practice, primary healthcare physicians commonly encounter patients with alcohol-related problems. This review article introduces the concept of an alcohol clinic for treating patients with these issues at primary healthcare clinics.Current Concepts: Alcohol-related problems often give rise to health problems, which prompts primary healthcare physicians to be required to develop screening, treatment, and counseling skills. Primary healthcare clinics should actively screen for alcohol-related problems. Screening involves questions regarding the frequency, quantity, and maximum consumption of alcohol to determine risk levels. For Koreans, moderate alcohol consumption is defined as ≤8 drinks per week (1 drink=14 g of alcohol) for men aged up to 65 years, and ≤4 drinks per week for men over 65 years; consumption for women is set at half of the amount defined for men. Individuals experiencing facial flushing after alcohol consumption are advised to limit their alcohol intake to half the amount consumed by those who do not experience flushing.Discussion and Conclusion: The focus for these patients should be on their environment, particularly when implementing a family-oriented approach. The decision to initiate drug treatment should be based on the symptoms of the patient, with follow-up evaluations performed at appropriate time points. The “FRAMES Motivational Enhancement Interview” and “Insight Enhancement Counseling” are recommended for an effective counseling of patients.

Sjogren syndrome is a chronic autoimmune disease characterized by lymphocytic infiltration of exocrine glands resulting in dry mouth and eyes. Approximately one-third of patients present with systemic manifestations, but respiratory muscle involvements have been rarely reported. We report a case of acute respiratory failure complicated by primary Sjogren syndrome. Muscle biopsy revealed perivascular lymphocytic infiltrations. Corticosteroid therapy improved respiratory muscle weakness. Sjogren syndrome should be considered as one of the underlying diseases causing acute respiratory failure.

Background:
Chronic stress is associated with an increased risk of cognitive impairment and Alzheimer’s disease. This study aimed to assess whether better coping with stress, as assessed using the Brief Resilience Scale (BRS), is associated with slower cognitive decline in community-dwelling older adults.
Methods:
This study used 2018/2019 data and 2-year follow-up data from the Korean Frailty and Aging Cohort Study. Of the 3,014 total participants, we included 1,826 participants (mean age, 77.6±3.7 years, 51.9% female) who completed BRS and Korean version of the Consortium to Establish a Registry for Alzheimer’s Disease Assessment Battery and the Korean version of the Frontal Assessment Battery (FAB).
Results:
Higher BRS score at baseline was associated with a lesser decline in the Mini-Mental State Examination score over 2 years after adjusting for age, sex, years of education, smoking status, hypertension, diabetes, and depression (B, 0.175; 95% confidence interval, 0.025–0.325) for 2 years, which represents global cognitive function. Other cognitive function measurements (Word List Memory, Word List Recall, Word List Recognition, Digit Span, Trail Making Test-A, and FAB) did not change significantly with the BRS score at baseline.
Conclusion
These findings suggest that better stress-coping ability, meaning faster termination of the stress response, may limit the decline in cognitive function.
