The humerus is anatomically and phyelologically unique, such as, firstly, it is a non weight bearing bone, secondly, it has greatest range of motion, thirdly, when at rest while the person is standing, the axis of bone hangs vertically and is influenced by gravity, and conservative methods usually used in treatment. However, in the event of closed reduction failure, open fracture, multiple fracture, and old age, operative method may be employed. Authors reviewed and analzed 84 humeral shaft fractures which had been treated at the Department Orthopedic Surgery, Paik Hospital from Dec. 1979 to May 1988. The results were as follows : l. Among the 84 patients, male were 63 and female were 21. 2. The major causes of injury were a traffic accident. 3. The most frequent type and site of fracture was comminuted and middle one third. 4. The incident of radial nerve injury was 17 cases. 5. Of 84 cases, 22 cases were treated conservatively and 62 cases operatively. 6. The most common complication was non-union of 14 cases, of which 10 cases were treated with plate and bone graft and 4 cases with only bone graft.

Radiographic measurement of cervical spine is very important in cervical spine injury especially those without fracture. Authors measured the retropharyngeal space, retrotracheal space, lordortic curve and sagittal diameter of cervical spinal canal in 148 cases of normal adult male. The results are as follows: 1 . In normal Korean adult male maximum retropharyngeal space is 7mm in C, level and Smm in Cs level. Maximum retrotracheal space is 16mm in C, level. 3. Loss of normal lordotic curve is shown in 21 cases(14.2%), 4. Average sagittal diameter of C, level is 21.27mm-it's the largest of all the cervical spinal cana1s, and that of C, level is 16.15mm-it's the smallest.

There are many experiences and principles about posterior approach in the spine as surgical procedure in the treatment of the patients with low back pain. And the anterior approach to the disc with its excision and bone graft, less known to others, has become a relatively safe procedure with the increasing experience. The greatest advantage of anterior lumbar interbody fusion is that the reduction of lumbar vertebral slipping is possible, the distance between the involved bodies is well maintained and the rate of fusion increases by spreading the vertebral bodies and putting into the measured bone bloc especially in the patients with severe segmental instability or spondylolisthesis. We analysed 48 patients having anterior interbody fusion by using a specially designed reduction-spreader during eight years, from January 1.978 to December 1985. The results were as follows: 1. Among 48 cases, 20 cases were male and 28 cases were female; 12 cases were in the fourth decade and 19 cases were in the fifth decade-most common in the fifth decade. 2. 28 cases were at the level of L4–L5, 16 cases were L5–S1, and 4 cases were two levels(L3–L4 L4–L5 and L4–L5 LS–Sl). 3. Retroperitoneal approach was used for the L3–L4 and L4–L5, and transperitoneal approach was used for the L5–S1. 4. After distraction between the involved vertebral bodies using an effective device, reduction-sprea-der, a pair of full thickness iliac bone grafts were impacted into the interspace, maintaining the reduction after removal of the reduction-spreader. 5. Fusion was achieved between 3 months and 6 months in 46 cases except 2 cases. 6. Overall clinical results were as follows: good in 42 cases, fair in 6 cases. 7. The anterior interbody fusion using the reduction-spreader is found to be useful method in the treatment of low back pain with spinal instability diagnosed by lumbar flexion-extension lateral roentgenograms.

The regulated production of reactive oxygen species (ROS) has been considered a unique property of phagocytic cells which use this ROS system to induce innate defense system that enables it to successfully combat the pathogens. However, the mechanisms for how respiratory mucosa might produce ROS against respiratory viral infection still need to be completely defined. Respiratory mucosa and nasal epithelium has been known as the first defense site of human respiratory tract which is highly exposed and vulnerable to environmental pathogens, including air-bone microbes, viruses and allergens. We are especially interested in the innate immune response to respiratory virus infection in nasal epithelium and how this response might be influenced by ROS generation after viral infection. The interferon (IFN) signaling system is perhaps the most critical pathway for antiviral defense and protective actions of IFNs rely on signaling through IFN receptors, transcription factors and IFN-stimulated genes or antiviral cytokines requiring for virus degradation and suppression of viral transcription or translation. We verified that both type I and type III IFN genes expression and secreted proteins were more highly induced after influenza A virus infection in nasal epithelium. We also propose that type III IFNs are the primary IFNs to mediate an anti-viral defense in nasal epithelium and more sensitively reacted with ROS which were produced after respiratory virus infection. We estimate that ROS are necessary for the innate immune response and trigger the induction of IFN-related innate immune response to resist respiratory virus infection in human respiratory mucosa.

Objectives: . Host–microbial commensalism can shape the innate immune response in the nasal mucosa, and the microbial characteristics of nasal mucus directly impact the mechanisms of the initial allergic responses in the nasal epithelium. We sought to determine alterations of the microbial composition in the nasal mucus of patients with allergic rhinitis (AR) and to elucidate the interplay between dysbiosis of the nasal microbiome and allergic inflammation. Methods: . In total, 364,923 high-quality bacterial 16S ribosomal RNA-encoding gene sequence reads from 104 middle turbinate mucosa samples from healthy participants and patients with AR were obtained and analyzed using the Quantitative Insights into Microbial Ecology pipeline. Results: . We analyzed the microbiota in samples of nasal mucus from patients with AR (n=42) and clinically healthy participants (n=30). The Proteobacteria (Ralstonia genus) and Actinobacteria (Propionibacterium genus) phyla were predominant in the nasal mucus of healthy subjects, whereas the Firmicutes (Staphylococcus genus) phylum was significantly abundant in the nasal mucus of patients with AR. In particular, the Ralstonia genus was significantly dominant in the clinically healthy subjects. Additional pyrosequencing data from 32 subjects (healthy participants: n=15, AR patients: n=17) revealed a greater abundance of Staphylococcus epidermidis, Corynebacterium accolens, and Nocardia coeliaca, accounting for 41.55% of mapped sequences in the nasal mucus of healthy participants. Dysbiosis of the nasal microbiome was more pronounced in patients with AR, and Staphylococcus aureus exhibited the greatest abundance (37.69%) in their nasal mucus, in association with a positive response to house dust mites and patients’ age and height. Conclusion . This study revealed alterations in the nasal microbiome in the nasal mucus of patients with AR at the levels of microbial genera and species. S. aureus-dominant dysbiosis was distinctive in the nasal mucus of patients with AR, suggesting a role of host-microbial commensalism in allergic inflammation.

OBJECTIVES: The aim of this study was to observe the nystagmus of totally unilateral vestibular function loss on galvanic vestibular stimulation and the diagnostic value of galvanic vestibular stimulation. Additionally we wanted to evaluate which portions may be stimulated by galvanic vestibular stimulation. MATERIALS AND METHODS: We evaluated the three parameters of galvanic stimulation in fourteen patients with totally unilateral vestibular function loss, 1)spontaneous nystagmus, 2)galvanic stimulating nystagmus, 3)Post galvanic stimulating nystagmus through 3-dimensional video-oculography technique. RESULTS: When negative electrode was attached to the intact side, The nystagmus on galvanic vestibular stimulation was directed to the negative electrode side in all patients and post galvanic stimulating nystagmus was directed to the opposite side but on functional loss side, we couldn't detect any nystagmus on galvanic vestibular stimulation and in 10 patients, post galvanic stimulating nystagmus was observed and directed to the intact side. CONCLUSIONS: Galvanic vestibular stimulation is very useful for evaluating the vestibular function and for diagnosing the vestibular disease.

Sleep apnea is a sleep disorder that includes symptoms such as snoring and apnea during sleep and daytime drowsiness. This disorder reduces a person’s quality of life and can also cause serious problems that interfere with one’s social life. Both non-surgical, such as positive pressure treatment, and surgical treatments can be performed to improve sleep apnea. Polysomnography is first needed to confirm the degree of sleep apnea before surgery and should be conducted in certified facilities according to strict regulations. While appropriate treatment for sleep apnea can be implemented based on polysomnography results, it is burdensome for patients to obtain a polysomnography examination because of the high cost. To increase the accessibility of polysomnography to patients, the government has implemented an insurance program for patients who meet certain criteria. Recently, these criteria have been revised. The purpose of this paper is to provide information on the latest health insurance criteria for polysomnography.

Chordomas are rere tumors arising from the primitive notochord. The commonest affected segment is the sacrum and these chordomas frequently follow a progressive course eith multiple recurrences and metastases and eventual death due to tumor.This report describes two cases of sacrococygeal chordomas with widespread metastases treated by surgery and adjuvant radiation therapy.
