Background: Current international guidelines recommend against deep sedation as it is associated with worse outcomes in the intensive care unit (ICU). However, in Korea the prevalence of deep sedation and its impact on patients in the ICU are not well known. Methods: From April 2020 to July 2021, a multicenter, prospective, longitudinal, noninterventional cohort study was performed in 20 Korean ICUs. Sedation depth extent was divided into light and deep using a mean Richmond Agitation–Sedation Scale value within the first 48 hours. Propensity score matching was used to balance covariables; the outcomes were compared between the two groups. Results: Overall, 631 patients (418 [66.2%] and 213 [33.8%] in the deep and light sedation groups, respectively) were included. Mortality rates were 14.1% and 8.4% in the deep and light sedation groups (P = 0.039), respectively. Kaplan-Meier estimates showed that time to extubation (P < 0.001), ICU length of stay (P = 0.005), and death P = 0.041) differed between the groups. After adjusting for confounders, early deep sedation was only associated with delayed time to extubation (hazard ratio [HR], 0.66; 95% confidence inter val [CI], 0.55– 0.80; P < 0.001). In the matched cohort, deep sedation remained significantly associated with delayed time to extubation (HR, 0.68; 95% 0.56–0.83; P < 0.001) but was not associated with ICU length of stay (HR, 0.94; 95% CI, 0.79–1.13; P = 0.500) and in-hospital mortality (HR, 1.19; 95% CI, 0.65–2.17; P = 0.582). Conclusion In many Korean ICUs, early deep sedation was highly prevalent in mechanically ventilated patients and was associated with delayed extubation, but not prolonged ICU stay or in-hospital death.

The incidence rate of cervical cancer in Korea is still higher than in other developed countries, notwithstanding the national mass-screening program. Furthermore, a new method has been introduced in cervical cancer screening. Therefore, the committee for cervical cancer screening in Korea updated the recommendation statement established in 2002. The new version of the guideline was developed by the committee using evidence-based methods. The committee reviewed the evidence for the benefits and harms of the Papanicolaou test, liquid-based cytology, and human papillomavirus (HPV) testing, and reached conclusions after deliberation. The committee recommends screening for cervical cancer with cytology (Papanicolaou test or liquid-based cytology) every three years in women older than 20 years of age (recommendation A). The cervical cytology combined with HPV test is optionally recommended after taking into consideration individual risk or preference (recommendation C). The current evidence for primary HPV screening is insufficient to assess the benefits and harms of cervical cancer screening (recommendation I). Cervical cancer screening can be terminated at the age of 74 years if more than three consecutive negative cytology reports have been confirmed within 10 years (recommendation D).

The pneumonia severity index (PSI) and CURB-65 are widely used tools for the prediction of community-acquired pneumonia (CAP). This study was conducted to evaluate validation of severity scoring system including the PSI and CURB-65 scores of Korean CAP patients. In the prospective CAP cohort (participated in by 14 hospitals in Korea from January 2009 to September 2011), 883 patients aged over 18 yr were studied. The 30-day mortalities of all patients were calculated with their PSI index classes and CURB scores. The overall mortality rate was 4.5% (40/883). The mortality rates per CURB-65 score were as follows: score 0, 2.3% (6/260); score 1, 4.0% (12/300); score 2, 6.0% (13/216); score 3, 5.7% (5/88); score 4, 23.5% (4/17); and score 5, 0% (0/2). Mortality rate with PSI risk class were as follows: I, 2.3% (4/174); II, 2.7% (5/182); III, 2.3% (5/213); IV, 4.5% (11/245); and V, 21.7% (15/69). The subgroup mortality rate of Korean CAP patients varies based on the severity scores and CURB-65 is more valid for the lower scores, and PSI, for the higher scores. Thus, these variations must be considered when using PSI and CURB-65 for CAP in Korean patients.

A choriocarcinoma of the rectum is extremely rare and has a very poor prognosis. Its rarity and the obscurity of its histogenesis make the entity of disease hard to define. We report a case of a choriocarcinoma of the rectum which showed synchronous liver and lung metastasis. A 52-year- old male patient presented with tenesmus, hematochezia and pain on defecation for 4 months. The preoperative colonoscopy revealed a mass at the rectum, 3 cm proximal to the anal verge. The biopsy revealed a poorly differentiated adenocarcinoma. An abdominoperineal resection was performed, and the pathologic examination confirmed a choriocarcinoma arising from an adenocarcinoma. Immunostain for beta-human chorionic gonadotropin (hCG) was strongly positive for the choriocarcinoma component. Serum hCG checked postoperatively was as high as 4,222 IU/L, but the serum carcinoembryonic antigen (CEA) was normal. Although chemotherapy was begun at the 5th week after the operation, the patient died on the 47th day after the operation. A choriocarcinoma of the colon or the rectum is very rare and is aggressive. Although radical resection and chemotherapy are performed, the clinical outcome is very disappointing. Even though a choriocarcinoma of the colon or the rectum is very rare, it should be included on the list for differential diagnosis of a colorectal carcinoma.

PURPOSE: Iliac vein compression syndrome (IVCS), first characterized by Cockett and Thomas in 1965, is the development of iliofemoral deep venous thrombosis due to compression of the left common iliac vein against the spine and pelvic brim by the right common iliac artery. Thrombectomy treatment of the underlying compression is essential if significant long-term sequelae are to be avoided. Surgical treatment options include venous reconstruction or venous bypass, but treatment using endovascular techniques have recently been described. This study was conducted to evaluate the usability of endovascular treatment (esp. thrombolysis with stent insertion) in a venous outflow obstruction resulting from IVCS. METHOD: During a 2-year period, 20 patients (17 women, 3 men; mean age, 60 years) presented with clinical and imaging findings consistent with IVCS. All patients presented with leg edema or pain. The mean duration of symptom onset was 6.6+/-4.4 days, ranging from 1 to 15 days. All patients were evaluated using a Duplex scan, computerized tomography and venography. After the ascending venography had been performed, an infusion catheter system was placed, and urokinase infused locally into the thrombus burden. After near complete clot dissolution, the residual left common iliac vein stenosis was treated by means of angioplasty and the placement of a Wallstent. All patients continued to receive oral warfarin. Patients were followed-up by means of clinical visits, and the stent patency was assessed by means of a Duplex scan or computerized tomography. RESULT: The total dose of urokinase used and the duration of infusion were 2.28+/-0.93 million unit, ranging from 1.00 to 5.20 and 46.8+/-14.8 hours, ranging from 14 to 72 hours, respectively. Grade III (complete lysis) thrombolysis was achieved in 17 patients. All 17 patients successfully received a Wallstent. The initial clinical success was 100%, with complete resolution of symptoms in all patients. One patient, with combined ovarian cancer, had a recurrent symptomatic deep vein thrombosis and complete occlusion of the stent due to thrombosis 2 months after treatment. However, no other patients showed evidence of deep vein thrombosis after treatment. The overall patency rate of the stenting at 18 months was 94.1%. There were no deaths, pulmonary embolism, cerebral hemorrhage or major bleeding complications. CONCLUSION: These results suggested that the treatment of iliac vein compression syndrome, using catheter directed thrombolytic therapy and venous stent insertion, was a safe and effective method at the mid term evaluation. These patients will continue to be followed up with screening tests to further define the long-term patency.

As a nursing practice involves nurses'actions in a specific context of health care, this study has focused on exploring the espoused theories in nursing practice within the action science perspectives. Espoused theories are the belief, principles, and rationale expressed by the practitioner as guiding her/his actions in a situation of practice. The data were analysed qualitatively and 25 elements of espoused theories of nursing action were identified and clustered into 6 categories. The 25 elements of espoused theories are as follows: The clinical nurse worked in wholistic and individual nursing, focussed on the patient's needed, comfort and supportive nursing (5 theories of nursing goal); excellent skills, knowledge based, assessment and data collection, explaining, educating or a scientific basis(6 theories of nursing intervention): advocacy, value oriented, treatment, accountability and commitment(4 theories of nursing ethics); human respect, partnership, trust(3 theories of patient-nurse relationship) : knowledgable, accumulated clinical experiences and personally lived experiences, positive perspectives(4 theories of nurse), role of intervention, rewarding, peer relationship(3 theories of situations). The above mentioned espoused theories are similar to that of nursing textbooks which students learned through basic nursing education and almost the same as the Acts ofa Nurse in Korean. However, we are doubtful whether nurses actually do as they think. Therefore, it is recommended to review the theories-in-use in order to find any discrepancies between the espoused theories and the reality of nursing actions.

BACKGROUND: In many epidemiologic reports of distribution of skin diseases, the outpatients of university hospitals have been the target groups of the analysis. But there has been no epidemiologic study of dermatoses in the field of rural area. OBJECTIVE: The purposes of this study were to investigate the distribution of skin diseases in rural areas and to evaluate the rural population's concept of skin disease and the attitude to their skin problems. METHOD: We analysed the results of interview and responses of questionnaires from 481 residents who visited the local public health centers and the free clinics in the rural areas of Kyonggi-Do and Ulsan city. RESULTS: The results of the study are summarized as follows : 1. Of 481 residents, there were 328 females and 153 males. The mean age was 56.6 years old. The residents over 50 years old formed 73.2 percent of total population. 2. The common dermatoses were tinea pedis, onychomycosis, xerosis, seborrheic keratosis, chloasma, pruritus, hand eczema, contact dermatitis, lentigo, seborrheic dermatitis in order of frequency. 3. The cutaneous fungal infection was the most common dermatoses in each study population. 4. To treat skin diseases, 51.2% of the residents visited the drug store initially. 5. The major reason of not taking dermatological care in the rural population was customary habit. 6. The 39.5% of 238 respondents have used self-treatments, and 15.5% of 90 respondents have experienced side effects of self-treatments. 7. On the question about the negative concepts of dermatoses, 61.7% of 462 respondents agreed to the statement that dermatoses look unclean. 8. Half of the 463 respondents thought that dermatologic medicine was harmful. The 50.6% of the 328 respondents had no specific reason, and 34.1% experienced gastrointestinal trouble. 9. The most favorite type of dermatologic medicine was topical agent, which was preferred especially by the group of respondents using nonmedical service including drug store. CONCLUSION: The distribution of the skin diseases in rural areas was similar to other reported results except the high frequency of cutaneous fungal infection. This research could be a basis on the following epidemiologic studies of the skin diseases in rural areas. It is also suggested that the educational program to improve understanding of skin diseases should be performed in the rural areas.

BACKGROUND: New therapeutic modalities such as high dose chemotherapy and stem cell support have been tried to prolong the survival period of the patients with multiple myeloma. However, little is known about the criteria for the application of those new therapies. There are only a few reports for the prognostic factors of multiple myeloma in Korea. The purpose of this study is to analyze the prognostic factors affecting chemotherapy response and survival in patients with multiple myeloma. METHODS: We retrospectively analysed the clinical records of 122 patients who were newly diagnosed as multiple myeloma by SWOG criteria, between November, 1989 and April, 1997 at Asan Medical Center. RESULTS: 1) The peak incidence was the 7th decade and male to female ratio was 1.3:1. The most common presenting symptom at first diagnosis was bone pain. 2) Initial clinical stage was as followed: stage I in 17.2% , stage II in 16.4% and 66.4% in III. The immunoglobulin classes were IgG in 51.6%, light chain only in 25.4%, IgA in 16.4%, IgD in 4.1%, and non-secretory type in 2.5%. Plasma cell types in bone marrow were classified as plasmablastic type in 45.9%, plasmacytic type in 54.1%. 3) Eighty two patients who recieved chemotherapy more than 3 cycles were evaluable for chemotherapy response. Overall response rate was 69.5%. Factors affecting response to chemotherapy were serum creatinine level, plasma cell type, total plasma cell percentage and plasmablast percentasge of total nucleated cells in bone marrow. 4) For total 122 patients, overall median survival period was 21 months, and estimated 5 year survival rate was 23.5%. Factors affecting survival were serum creatinine, corrected calcium, albumin, beta2-microglobulin level, response to chemotherapy, total plasma cell percentage and plasmablast percentage in bone marrow. CONCLUSION: Bone marrow findings at initial diagnosis are significantly associated with response to chemotherapy and survival duration.
