With the increasing use of pedicular system to fix the spine, many complications are being reported. Recently many systems are available to fix the spine. However, each system has own advantages and disadvantages. The causes of metallic failure of Modular Segmental Spinal (MOSS) instrumentation on 42 consecutive patients undergone in Kang-Nam St. Mary's hospital since 1989 were reviewed. The specific aim of this investigation was to assess causes of metallic failure and loosening of this system on various spinal disorders. Of these, 8 cases had metallic failure and loosening. Breakage of screw and rod developed in 6 cases and dislodgement of rod from screw in 2 cases. In case of degenerative spondylolisthesis (unstable phase) with stenosis, however, the complications were closely correlated to expansile decompressive laminectomy to widen the narrowed spinal canal and the instrumental distraction to gain normal intervertebral disc space at the operation. Bony union and back pain were not correlated to metallic failure and loosening. Therefore, the main causes of metallic failure and loosening were (1) preoperative instability undergone expansile decompressive laminectomy including total bilateral facetectomy that aggravated preoperative instability, and (2) forceful instrumental dis traction. In cases needed these requirements, combined anterior interbody fusion or posterior interbody fusion should be added, heavier rods and screws larger than 3.5mm, 4.0mm in diameter, respectively, should be used. In addition to postoperatively sufficient bed rest and immobilization using rigid braces should be recommended to reduce these complications.

The management of fractures of the intercondylar eminence of the tibia is uncomplicated when the fracture has minimal displacement(type I) or when only anterior one-third or half of the eminence is elevated(type II)(Meyers and Mckeever 1959, 1970). The treatment of complete separation(type III) has been controversial. Many authors however recommended conservative treatment even for the completely separated fracture if the fracture fragment is not rotated. Two cases of non-union of the tibial spine fracture we experienced were; one in type IIl, and the other type II. They were treated conservatively by cast immobilization. One patient had severe anterolateral rotatory.instability and had lateral meniscal tear, and the other had transverse ligament impingement at the fracture gap which interfered the reduction of the fragment and also bony union. Through the clinical experience and the two listed non-union cases, we drafted a therapeutic plan for the avulsed tibial spine fractures. The authors recommend open reduction and internal fixation of the avulsion fracture of the tibial spine in following circumstance; 1) all of the type K complete separation injuries 2) tibial spine fracture with positive Lachman test and soft end point 3) fracture with associated ligament injury. We applied the above surgical indications for 13 cases. The authors reviewed 25 cases of the anterior tibial spine fracture patients treated at the Department of Orthopaedic Surgery, Catholic Unviersity Medical College during the period from October 1982 to August 1986 and the following results were obtained. 1. The cases were classified into 3 different categories according to the Meyers and Mckeever classification; Type I(7 cases, 29%), Type II(10 cases, 40%), Type III(8 cases, 31%). 2. Associated ligament injuries on the same knee were rupture of LCL for 7 cases(28%) and MCL for 6 cases(24%). 3. Twelve out of thirteen open reduction and internal fixation cases had excellentresult in minimum 6 months follow-up period.

Purpose: The purpose of this study was to develop and verify the effectiveness of the home-based exercise program for prevention of sarcopenia in hemiplegic disorder patients. Methods: The participants consisted of 26 experimental group and 26 control group with hemiplegic disorders. The home-based exercise program to prevent sarcopenia was conducted twice a week and for six weeks from 11 January 2021 to 19 April 2021, measuring muscle mass, muscular strength, daily life movements, balance, dynamic posture control ability and quality of life. Results: The results showed the effectiveness of the home-based exercise program for hemiplegic patients.There were statistically significant differences between the control group and experimental group in patients’ muscle mass (F=8.26, p=.006), muscle strength (F=7.99,p=.007) and quality of life (F=12.19, p=.001). But, there were not statistically significant in patients’ daily life movements (F=0.33, p=.565), balance (F=0.04, p=.841) and dynamic posture control ability (F=3.48, p=.068). Conclusion In conclusion, the home-based exercise program was effective in improving muscle mass, muscle strength and quality of life in hemiplegic patients. Therefore, it is expected that the home-based exercise program developed in this study will be applied as an intervention for prevention of sarcopenia in hemiplegic patients and will be effective.

BACKGROUND: The purpose of this study was to find out the effect of hypnotics and analgesics on oxygen saturation by pulse oximetry in surgery patients under spinal anesthesia. METHODS: Sixty-five patients classified ASA physical status 1 or 2 scheduled for surgery under spinal anesthesia were studied. These patients were divided into three groups. The 22 subjects of the first group did not receive either midazolam or fentanyl. The 22 subjects of the second group received midazolam. The 21 subjects of the third group received midazolam (0.03 mg/kg) and fentanyl (1.0 microgram/ kg). Oxygen saturation was measured with a pulse oximetry. Measurements were made before spinal anesthesia, 5 minutes, and 10 minutes after starting of spinal anesthesia, 5 minutes, 10 minutes, 30 minutes, and 60 minutes after the start of the operation or intravenous injection of drugs. In addition, measurements were made on arrival in the recovery room, and 5 minutes, 10 minutes, 20 minutes, and 30 minutes after arrival in the recovery room. RESULTS: There were statistically significant differences in oxygen saturation at 5 minutes after the start of the operation or intravenous injection of drugs. The mean oxygen saturation for the first group was 98.2 +/- 1.8%, for the second group 97.9 +/- 2.6%, and for the third group 92.4 +/- 2.8%. Hypoxia cases at 5 minutes after the start of the operation or intravenous injection of a drug occurred in 4.5% of the first group, 9.1% of the second group, and 57.1% of the third group CONCLUSIONS: We concluded that oxygen saturation monitoring should be done routinely in patients receiving hypnotics and analgesics during spinal anesthesia, and oxygen should be administered to patients who develope hypoxia during spinal anesthesia.

The number of latex-induced allergic reactions, including anaphylaxis, has been increasing since latex induced contact urticaria was first reported in surgical patients by Nutter in 1979. Latex allergy is frequently seen in the healthcare industry, and is associated with systemic symptoms, hand eczema, and allergic contact dermatitis. Reactions range from contact urticaria, rhinitis and conjunctivitis, angioderma or bronchospasm to the recently recognized severe anaphylactic shock with cardiovascular collapse. We encountered a 55-year-old female patient who developed a severe anaphylactic reaction after manual vetilatory support using a facemask that contained latex. A subsequent allergy workup revealed a delayed-type hypersensitivity to latex. This case highlights the need for anesthesiologists to be able to diagnose the signs and symptoms of allergic reactions in patients during the peri-anesthetic period. Two types of allergic reactions to natural rubber latex (NRL) and rubber products are now known to exist: type I (immediate-type) and type IV (delayed-type hypersensitivity [DTH]). Patients with NRL allergy should be provided with information on non-latex devices and latex avoidance in medical, dental, and occupational settings. In addition, we should pay more attention to the management of allergic reactions to latex in high risk groups.

Scrub typhus is an acute, febrile illness caused by Orientia tsutsugamushi infection and it is one of the main causes of acute febrile illness in the Asian-Pacific region. The incidence of scrub typhus has been significantly increased in Korea during last 10 years. Although early diagnosis and proper antibiotic treatment are important to prevent severe complications, the clinical discrimination of scrub typhus from other undifferentiated fevers, such as leptospirosis or dengue fever, is often very difficult. In addition, an effective vaccine has not yet been developed. As a novel diagnostic and vaccine target for scrub typhus, we described surface cell antigen (sca) family genes encoding autotransporter proteins found in the genome of O. tsutsugamushi. The molecular characteristics and recent findings on the bacterial genes were introduced in this letter.

PURPOSE: To evaluate the cause and surgical outcome of extensor pollicis longus rupture after distal radius fractures. MATERIALS AND METHODS: Nineteen cases in which the patients underwent surgical treatment for rupture of the extensor pollicis longus after distal radius fractures were followed for more than one year. Among the nineteen cases, fourteen extensor pollicis longus ruptures occurred after conservative treatment, four occurred after closed reduction with K-wire fixation, and one occurred after open reduction and internal fixation with a plate. All cases were treated by extensor indicis proprius transfer. RESULTS: Extensor pollicis longus ruptures were caused by K-wire irritation in two, by a protruding screw tip in one, and by a callus in one. In the conservative treatment group, tendon ruptures were diagnosed at an average of 3.1 months (0.7~17). Tendon ruptures were detected in the surgical treatment group at an average of 12.8 months (1~48). All the patients showed favorable recovery of the extension capability of the thumb at the final follow-up. CONCLUSION: The main cause of extensor pollicis longus rupture after distal radius fracture was ischemic damage. Therefore, during the surgery, the length and direction of screws and K-wires should be fixed carefully to avoid such damage. Distal radius fracture also requires careful observation of the extensor pollicis longus during follow-up. Furthermore, extensor indicis proprius transfer is considered to be an effective method for extensor pollicis longus rupture.

PURPOSE: Atypical patients of Kawasaki Disease (KD) are now discovered with increasing frequency. The goal of this study is to help diagnose and treat KD by comparing of clinical characteristics between typical and atypical KD. METHODS: We performed a retrospective analysis of 82 patients with typical or atypical KD from January 1993 to March 1997. RESULTS: Out of the 82 patients, 49 cases were diagnosed as having typical KD, while there were 33 cases of atypical KD. The mean age was 31.4 months and 25.5 months respectively. The rate of prevalence in the changes of extremities, polymorphous exanthema, and cervical lymphadenopathy was greater in typical KD than atypical KD. The number of patients with various combinations of the principal symptoms among the 33 atypical cases were 18. Mean duration of fever was 6.2 days in typical cases and 5.8 days in atypical cases. The most common clinical findings were cough and rhinorrhea in both groups and the most common disease was pneumonia CRP was significantly elevated in patients with typical KD than atypical cases. Coronary artery dilatations were confirmed by 2-D echo in 7 (19.4%) of 36 tested typical cases, while 2 (9.1%) of 22 tested atypical cases. Patients were treated with aspirin and high-doses of IV gamma-globulin. CONCLUSION: Atypical KD was characterized by the infrequent appearance of rash, cervical lymphadenopathy, changes of hands and feet. We thought that there wasn't a strong association between atypical KD and coronary involvement.
