The frozen section technique is a means of intraoperative pathological diagnosis, and a procedure of great value to the surgeon. This method should be accurate, rapid and reliable. This method serves useful purposes, such as determining the presence of tumor, its type (especially whether it is benign or malignant), the adequacy of a biopsy of a suspected lesion, and the conditions of the surgical margins. But, it bears many disadvantages, the most of which is the danger of incorrect diagnosis. We studied the indications, the limitations, and the accuracy of the frozen section method and the materials studies was total of frozen section diagnosis of 809 cases was 98.1% with 0.5% of false negative, 0% of false positive 0.5% of incorrect histological diagnosis or grading errors, and 0.9% of deferred cases. The tissues submitted were lymph node, gastrointestinal tract, skin subcutaneous tissues in decreasing oder of frequency. The false positive case is not present, while the false negative cases were 4.

Clinical and histopathological studies were made on 202 cases of malignancy of cervix, that were visited to the Department of Obstetrics and Gynecology, Yeungnam University Hospital, during 5 years from 1983 to 1987. The results were summarized as follows. 1. Malignancies of the uterine cervix were 10% of total female malignancies. 2. Among 202 cases, 195 cases (96.5%) were squamous cell carcinoma, in which 60 cases (30.0%) of carcinoma in situ, 9 cases (4%) of microinvasive, and 126 cases (62.5%) of invasive carcinoma were included. 3. The average age of the patients with squamous cell carcinoma was 49.4 years old; In case of carcinoma in situ, it was 43.8, microinvasive, 40.0, invasive 52.1 years old. 4. Clinical symptoms of the patient with squamous cell carcinoma in order of frequency were as follows; vaginal bleeding (47.5%), abnormal cytology (15.4%), and abnormal vaginal discharge (9.4%). 5. Duration of the chief complaints was most commonly less than 6 months (73.2%), and the average duration was 3.8 months. 6. The most common age of marriage was between 19 to 22 years old (46.5%). The average was 21.5 years old. 7. The gravity was 51.5% in 5-8 times, and average 6.2 times. The parity was 61.9% in 1-4 times, and average 3.9 times. 8. The subdivision of 126 cases of invasive carcinoma was made according to FIGO stage classification, stage I, 40 cases (31.8%), stage II, 54 cases(42.9%), stage III, 11 cases (8.7%), and stage IV, 8 cases (6.3%). 9. The histologic subtypes of invasive squamous cell carcinoma were distributed as follows; large cell keratinizing type, 25 cases (19.8%), large cell nonkeratinizing type, 101 cases (80.2%). 10.

PURPOSE: The purpose of this study was to investigate the present status of falls among inpatients in general hospitals and to identify the fall risk factors that reflect the characteristics of domestic hospitals. METHODS: Data were collected between December 15, 2016 and January 15, 2017 from 32 Korean hospitals having 500 or more beds. First, 42 risk factors were extracted based on literature review and expert opinions. Then the importance of each factor was evaluated by 223 nurses from medical and surgical adult ward and intensive care units in 40 hospitals. RESULTS: The incidence rate of falls in 18 hospitals was 3.87 per 1,000 total discharged patients and 0.55 per 1,000 patient-days, and the rate of injury-related falls was 40.5%. Major risk factors for falling were identified as the following: being over 65 years of age, history of falls during admission, physical mobility disorders requiring assistance, physical factors (dizziness or vertigo, unstable gait, general weakness, walking aids, visual problems), cognitive factors (delirium, lack of understanding on limitations), neurological disease, CNS medications CONCLUSION: The findings provide information that can be in the development of a fall risk assessment tool for inpatients in general hospitals in Korea.

PURPOSE: To evaluate the utility of FLAIR (Fluid Attenuated Inversion Recovery) MR imaging in cerebral infarction by comparing its results with those of T2-weighted spin-echo imaging. MATERIALS AND METHODS: We retrospectively evaluated fast FLAIR images and conventional spin echo images of 82 patients (47 men and 20 women; median age 60.9 years) with cerebral infarction. MR imaging used a 1.5T MR unit with conventional T2 (TR 3900, TE 90) and fast FLAIR sequence (TR 8000, TE 105, TI 2400). We analysed the size of the main lesion and number of lesions, and discrimination between old and new lesions and between small infarction and perivascular space. RESULTS: When T2-weighted and FLAIR imaging were compared, the latter showed that the main lesion was larger in 38 cases (46%), similar in 38 (46%), and smaller in six (7%). The number of lesions was greater in 23 cases (28%), similar in 52 (63%), and fewer in seven (9%). FLAIR images discriminated between old and new lesions in 31 cases ; perivascular space and small infartion were differentiated in eight cases, and CSF inflowing artifact was observed in 66 (80%). CONCLUSION: In the diagnosis of cerebral infaretion, fast FLAIR provides images that are equal or superior to T2-weighted images. The fast FLAIR sequence may therefore be used as a part of routine MR brain study in the diagnosis of cerebral infarction.

Although acquired ichthyosis has been associated with a number of systemic illnesses, an association with sarcoidosis has rarely been reported. We report a patient with aquired ichthyosis of the lower and upper extrimities whose diagnosis of cutaneous sarcoidosis was confirmed by histologic examination. Systemic involvement in the patient revealed occular, pulmonary and nerve disease. A diagnosis of sarcoidosis must be considered when a patient presents with acquired ichthyosis.

PURPOSE: There has been little research regarding the effectiveness of oseltamivir for influenza B infections. We sought to identify the different clinical manifestations between patients treated with and without oseltamivir. METHODS: We retrospectively studied the medical records of 72 inpatients or outpatients from two medical centers diagnosed with influenza B infections by either a rapid antigen test or multiplex reverse transcriptase PCR between January 2012 and July 2012. We compared gender, age, past medical history, admission period, total fever duration, fever duration after hospitalization, post-oseltamivir medication peak temperature, laboratory test, chest X-ray, antibiotic medication, and the presence of concomitant viral or bacterial infections. RESULTS: The number of subjects in our study was 72 who were diagnosed with influenza B pneumonia, acute bronchitis, acute bronchiolitis, croup, and mean age was 3.6+/-2.8 year old. The demographic characteristics and clinical manifestations of oseltamivir and the non-oseltamivir groups, including hospitalization period (4.18+/-2.10 vs 4.79+/-1.49 days, P=.17) and total fever duration (5.32+/-2.07 vs 6.41+/-3.25 days, P=.09), demonstrated no significant differences. Notably, the oseltamivir group did have significantly reduced usage of antibiotic treatment than the non-oseltamivir group (P=.04). When we limited our patient group to patients under the age of three, similar results were seen. The group prescribed oseltamivir within 48 hours of fever onset had less antibiotic usage, in addition to a shorter fever duration. CONCLUSION: Oseltamivir appeared to have no benefit in improving the clinical course. However, if it is prescribed within the first 48 hours of symptoms, it may be more effective.

Most of the malignant tumors of the pancreas are adenocarcinomas arising from the ductal epithelium. Primary leiomyosarcoma of the pancreas, even though it is the most common sarcoma of the pancreas, is very rare. We present a case of leiomyosarcoma of the pancreas, probably primary, with metastases to the stomach, lymph nodes, and abdominal wall. A 52-year-old woman visited the hospital with vague right upper abdominal pain and weigh loss of 6 kg for 2 months. The radiological and endoscopic examination revealed that she had a large heterogeneous mass, 11 cm in size, in the pancreatic body and tail, a 4 cm-sized mass in the paraaortic area, and a 3 cm-sized polypoid mass in the stomach. Histologically, they were all similar to one another and composed of markedly pleomorphic cells. Immunohistochemical and electron microscopic studies showed definite smooth muscle differentiation of the tumor cells. Two months later, the patient underwent an excision of a new 3 cm mass in the right lower abdominal wall, showing features of well differentiated leiomyosarcoma.

Congenital adrenal hyperplasia is inherited disorder of adrenal steroidogenesis. 21-hydroxylase deficiency is the most commone enzymatic defect and is divided into classic and late-onset or nonclassic forms. Both classic non-classic 21-hydrozylase deficiencies are inherited in a recessive manner as allelic variants. But it is rare that happened in twin infants. Chief complaints of affected twins in our case were ambiguous genitalia, hyperpigmentation and dehydrations. They were revealed into hyponatremia, hyperkalemia and increased amount of serum progesterone, 17-hydroxyprogesterone and urinary 17-ketosteroid excretion and were administered with DOCA, 9alpha-fluorohydrocortisone, hydrocortisone to control the electrolyte imbalance. And now, both of them are going to normal ratio of weight gain and body growth.
