BACKGROUND: There have been no studies of airway management strategies for difficult intubation and cannot intubate, cannot ventilate (CICV) situations in Korea. This study was intended to survey devices or methods that Korean anesthesiologists and intensivists prefer in difficult intubation and CICV situations. METHODS: A face-to-face questionnaire that consisted of a doctor's preference, experience and comfort level for alternative airway management devices was presented to anesthesiologists and intensivists at study meetings and conferences from October 2014 to December 2014. RESULTS: We received 218 completed questionnaires. In regards to difficult intubation, the order of preferred alternative airway devices was a videolaryngoscope (51.8%), an optical stylet (22.9%), an intubating laryngeal mask airway (11.5%), and a fiber-optic bronchoscope (10.6%). One hundred forty-two (65.1%) respondents had encountered CICV situations, and most of the cases were identified during elective surgery. In CICV situations, the order of preferred methods of infraglottic airway management was cricothyroidotomy (CT) by intravenous (IV) catheter (57.3%), tracheostomy by a surgeon (18.8%), wire-guided CT (18.8%), CT using a bougie (2.8%), and open surgery CT using a scalpel (2.3%). Ninety-eight (45%) of the 218 respondents were familiar with the American Society of Anesthesiologists' difficult airway algorithm or Difficult Airway Society algorithm, and only 43 (19.7%) had participated in airway workshops within the past five years. CONCLUSION: The videolaryngoscope was the most preferred device for difficult airways. In CICV situations, the method of CT via an IV catheter was the most frequently used, followed by wire-guided CT method and tracheostomy by the attending surgeon.

BACKGROUND: The skin of patients with atopic dermatitis (AD) exhibits a striking susceptibility to colonization with Staphylococcus aureus (S. aureus). Superantigens produced by S. aureus and their specific IgE antibodies are thought to be important precipitating factors of AD, but there are few reports evaluating these 2 factors at the same time, particularly in adult AD patients. OBJECTS: Our purpose was to investigate the differences in the culture degree of S. aureus from the lesion, non-lesion, and control group of child and adult AD patients, to research the correlation between the exotoxin production, total IgE, anti-SEA IgE and the disease severity by SCORAD index, to ascertain the differences between child and adult AD patients. METHODS: The clinical severity of 30 child (2 to 15 years of age) and 30 adult patients (16 to 40 years of age) with AD was evaluated by using SCORAD index. S. aureus was isolated from lesional and non-lesional skin of AD patients, and from healthy controls. Staphylococcal exotoxins were detected by using reversed passive latex agglutination toxin detection kits. Anti-SEA IgE antibody was determined by using AlaSTATt assay RESULTS: S. aureus colonizations were found in 11 (36.7%) of the lesional skin, in 5 (16.7%) of the non-lesional skin of 30 child AD patients, and in 26 (86.7%), in 20 (66.7%) of 30 adult AD patients, respectively. The colonization rates of S. aureus in child patients were much lower than those in adult patients, both form lesional skin and non-lesional skin. Staphylococcal exotoxins were detected in 5 (45.5%) of the 11 colonizations from lesional skin, in 2 (40%) of the 5 colonizations from non-lesional skin of children, and in 10 (38.5%) of the 26 colonizations, in 9 (45%) of the 20 colonizations of adults, respectively. Staphylococcal enterotoxin A (SEA) was most frequently detected in both groups. S. aureus colonization was correlated with the severity of AD in childhood, but not in adulthood. However, there were no statistical significances between severity of AD and others such as exotoxin production, and the level of total IgE and anti-SEA IgE in both groups. CONCLUSION: The colonization of S. aureus was more common in adult AD patients than child AD patients. Anti-SEA IgE level was much higher in adult AD patients than in child AD patients. It is tempting to speculate that the colonization of S. aureus and exotoxin production might be related to the disease. duration rather than clinical severity of AD.

Increasing numbers of atypical subtrochanteric fractures have been reported among long-term bisphosphonate users. However, the nature and extent of the problem are unknown despite recent investigations. The task force of American Society for Bone and Mineral Research (ASBMR) defined major and minor features of complete and incomplete atypical femoral fractures; transverse or short oblique orientation, minimal or no associated trauma, a medial spike when the fracture is complete, and absence of comminution. Minor features include their association with cortical thickening, a periosteal reaction of the lateral cortex, prodromal pain, bilaterality, delayed healing, comorbid conditions, and concomitant drug exposures, including bisphosphonate, glucocorticoids, and proton pump inhibitors. Based on published data, the incidence of atypical femoral fractures associated with bisphosphonate therapy for osteoporosis appears to be very low, particularly compared with the number of vertebral, hip, and other fractures that are prevented by bisphosphonate. Physicians and patients should be aware of the possibility of atypical femoral fractures and of the potential for bilaterality.

A histopathological study of erythema nodosum-like lesions in Behcet's disease was performed on 55 patients with incomplete and suspect types of Behcet's disease. Relatively common characteristics in histopathology of erythema nodosum-like lesions could be found in the patients with incomplete type of Behcet's disease. The histopathologic findings of erythema nodosum-like lesions in 21 patients with incomplete type of Behcet's disease were as follows : l. A moderate lymphocytic infiltration was found around the blood vessels and the sweat glands in the dermis. In the subcutaneous tissue, besides lymphohistiocytic infiltration, neutrophils were present in significant number in 9 cases (42.9%) 2. Vasculitis of small vessels was found within the periphery of fat lobules in 7 cases (81.0%), Five cases (23.8%) also showed thrombophlebitis. Seven cases (33.3%) showed histiocytic granuloma formation within the fat lobules. Microabscess formation in the subcutaneous tissue was seen in 5 cases (23.8 %), but it was not certain whether this was the charateristic feature.

The femoral neck in children is dense and is small in diameter and its periosteum is thicker and stronger than that of an adult. Thus, fractures of the femoral neck in children, unlike the 60-year-old woman, are rare and usually require severe violence and this accounts for the high frequency of associated injuries. Since these fractures are rare and the femoral neck in children has many anatomic and physiologic differences, we have to consider some factors that work against treatment of these fractures. Twenty seven cases of fractures of the femoral neck in children which were treated at Severance Hospital, Yonsei University College of Mediicne from Jan. 1971 to Dec. 1980 were analyzed both clinically and radiologically and the following results were obtained. 1. Among the 27 patients, the ratio of boys and girls was 2:1 and the highest incidence was between the ages of 3 and 5 years. 2. The main course of fractures was traffic accidents, 14 cases (51.9%) and the other causes were falling from a height (37.0%) and a few cases of a slip and a fall. 3. According to the classification of Delbet and Colonna, the cervico-trochanteric fracture (40.8%) was the commonest type and 13 cases (48.1%) were displaced fractures. 4. Common associated injuries were pelvic bone fractures, skull fractures, cerebral concussion and soft tissue injuries. 5. Fifteen cases (55.6%) were treated by conservative treatment and ten cases (37.0%) by closed reduction & internal fixation. 6. 23 of the 27 cases were followed for from 6 months to 10 years, average 19 months. The results were analyzed according to Ratliffs assessment and 14 cases (60.9%) showed good results. 7. Total cases with complications were 14 (60.9%), the commonest complication being coxa vara (40.8%) and the other main complications being premature epiphyseal closure (39.1%) and avascular necrosis (30.1%). 8. Secondary treatment was done in 6 cases and correction osteotomy was done in 4 cases which had showed a poor result. 9. Finally, factors affecting results were type of fracture, degree of displacement, maintenance of reduction, interval between injury and treatment, complications and patients age. 10. The authors recommend closed reduction and internal fixation with some threaded pins for all type II and type III fractures.

Primary non-Hodgkin's lymphoma of the brain is a rare malignancy and there are known to occur almost exclusively in brain parenchyme. Recent immunological advances and immunohistochemical techniques have provided new insights into the pathogenesis and diagnosis of the malignant lymphoma even in the small biopsied tissue and the majority of these CNS tumors is thought to be derived from B lymphocytes. A 22-year old man was admitted due to headack, dizziness and walking difficulty for 2 months. On the initial CT scan, there were two enhancing lesion in the suprasellar area and pineal gland which were completely disappeared with steroid therapy and three new lesions appeared on the follow-up CT and MRI studies in corpus callosum, third ventricle and left cerebral peduncle. The serial cytologic smears of cerebrospinal fluid and a stereotaxic biopsy tissue from the corpus callosum mass showed diffusely homogenous infiltration of neoplastic large noncleaved lymphocytes with focal perivascular arrangement. On the immunocytochemical stains, the reaction was negative for GFAP, positive for LCA and MB2, and negative for MT1. After radiation therapy, the masses completely disappeared on the follow-up CT scan and the patient was discharged free of all the clinical symptoms.
