  • Bacteria isolated from nasal cavity of 50 Thoroughbred horses with respiratory tract infection were examined. There were isolated Pseudomonas aeruginosa(33.5%), Escherichia coli(10.2%), Pseudomonas spp(7.6%), Klebsiella oxytoca(5.9%), Streptococcus equi subsp zooepidemious(6.2%), Klebsiella pneumoniae(3.4%), Acinetobacter spp(5.5%) and coagulase negative staphylococcus(2.1%). The majority of isolates were highly susceptible to amikacin, amoxicillin, aztreonam, cefotaxime, cefepime, cefotetan, ceftazidime, cefuroxime, chloramphenicol, ciprofloxacin, clindamycin, erythromycin, gentamicin, imipenem, tetracyclin and vancomycin. These results can provide basic information for the treatments of respiratory tract infections in Thoroughbred horses.

  • Epigallocathechin-3-gallate (EGCG), the main polyphenol component in green tea, inhibits angiogenesis, urokinase, and matalloproteinases, and EGCG also has the antioxidative property. Recent reports proposed that EGCG may modulate the immune response on allergy or asthma. Human nasal mucosal fibroblasts are a rich source of cytokines, inflammatory mediators, and chemokines. Chemokines are important for the recruitment of leukocytes to sites of infection, which is essential in host defense. The objective of this study was to investigate the effect of EGCG on the expression of the chemokines such as RANTES (regulated upon activation, normal T cell expressed and presumably secreted), eotaxin, and interleukin-8 (IL-8) in human nasal mucosal fibroblasts after stimulation with cytokines like IL-4, tumor necrosis $factor-{\alpha}\;(TNF-{\alpha})$, and $interferon-{\gamma}\;(IFN-{\gamma})$. To detect the expression of chemokine genes, RT-PCR was performed. Expressions of RANTES, eotaxin, and IL-8 mRNA stimulated with IL-4 and $TNF-{\alpha}$ were increased, respectively, while the expression of those genes incubated with $IFN-{\gamma}$ was similar pattern compared to control group. Analyses of chemokine genes of cells pretreated with EGCG showed that the expressions of eotaxin, and IL-8 genes stimulated $IFN-{\gamma}$ were higher compared with those not pretreated with EGCG.

  • Purpose : In February 2007, an outbreak of methicillin-resistant Staphylococcus aureus (MRSA) skin and soft tissue infections occurred in two newborns in the neonatal unit of Sahmyook Seoul Hospital. We performed this study to investigate the characteristics of MRSA nasal carriage among neonatal unit staffs and the effective infection control measures. Methods : Nasal swab specimens were obtained from the neonatal unit staff for the presence of MRSA. MRSA-colonized staffs were offered decolonization therapy with oral trimethoprim-sulfamethoxazole or 2% mupirocin ointment. Every 2-4months after decolonizaton, repeat nasal swab specimens were obtained. Also, samples from the neonatal unit environment and room air were collected. Results : Successful decolonization was achieved in 92% of the cases in 2 weeks after decolonization therapy, but most of the staffs were recolonized after several months. The nature of antibiotic susceptibility was changed from multi-drugsusceptible to multi-drug-resistant. The most frequently contaminated objects were dressing carts, computer keyboards, bassinets and washbowls. In environmental cultures using the settle microbe count method, the colony counts were decreased significantly at the last study period compared with the first study period in the neonatal room, breastfeeding room, service room, and dressing room (P <0.05). Conclusion : Effective control of sustained MRSA transmission within an institution may require prompt identification, treatment, and monitoring of colonized and/or infected staffs. However, nasal decolonization therapy may induce multi-drugresistant MRSA infection and had no effect on decreasing the MRSA nasal carriage rate in our study. Other factors might be more important, such as improving staff education, increasing hand hygiene practices, and environmental sterilization for controlling MRSA infections.

  • Nasal bone fractures are often accompanied by septal fractures or deformity. Posttraumatic nasal deformity is usually caused by septal fractures. Submucosal resection and septoplasty are commonly used surgical techniques for the correction of septal deviation. However, septal perforation or saddle nose deformity is a known complication of submucosal resection. Hence, we chose to perform septoplasty, which is a less invasive procedure, as the primary treatment for nasal bone fractures accompanied by septal fractures. During septoplasty, we used a bioabsorbable mesh as an internal splint. We used the endonasal approach and inserted the mesh bilaterally between the mucoperichondrial flap and the septal cartilage. The treatment outcomes were evaluated by computed tomography (CT) and the nasal obstruction symptom evaluation (NOSE) scale. The CT scans demonstrated a significant improvement in the septal deviation postoperatively. The symptomatic improvement rated by the NOSE scale was greater at 1 month and 6 months after surgery compared to the preoperative status. There were no cases of extrusion or infection of the implant. In cases of moderate or severe septal deviation without dislocation from the vomerine groove on the CT scan, our technique should be considered one of the treatments of choice.

  • A dairy farm that has been suffered continuously(more than 2 years) from brucellosis in Korea in spite of repeated legal test-and-slaughter was investigated the main source of infection in the farm. All cattle(22 milking cows, 44 heifers, 60 calves, 8 bull), dogs(3 mixed breed), feces from wild birds(3 samples), drinking water(3 sites), and soil in the paddocks(14 sites) inside the farm were examined with serological and/or bacteriological methods including specific DNA detection with PCR method. Brucella spp in the milk and blood were detected in 12/22 and 5/22 milking cows, respectively, although all of them were negative with conventional tube agglutination test. The number of serologically positive heifer was 15(15/44), but the isolation of Brucella spp was succeeded in the only 11(11/15) of them. Brucella were detected in vagina 1(1/11) and nasal(3/12) excretion in serologically positive heifers. All the three dogs were serologically positive, and Brucella spp were isolated from their blood. However, Brucella spp were not detected in the drinking water, soil in the paddocks, nor the feces of wild birds. The results suggest that milking cow secrete Brucella spp through milk, genital tract and nasal cavity, which are the major source of infection in this farm, The main infection route of Brucella spp is contact to contact with Brucella spp excreting animals rather than environmental contamination. The animals, living together with infected cow such as dogs, are the readily susceptible and are required to be examined for Brucella spp.

  • For the epidemiological studies of the respiratory infection from 1,918 heads of adult rabbits from January 1980 to December 1985 at an integrated farm, the causative agents were. Isolated samples 92 from of lungs and nasal discharges, and identified by serological and non-serololgical tests, the loss rates by the infection were also investigatyed, and the antimicrobial sensitivities of the isolates were determined. The results obtained were as fellows : 1. The loss rate by respiratory infection was 11.9% among 1,819 heads which raised and 41.7% among 518 heads which lost by diseases, and the rate increased annually. 2. The loss rate of rabbits in Spring (45.0%), Summer (45.5%) and Winter (53.5%) showed significantly higher (P < 0.01) than that in Autumn(29.1%). 3. The loss rate of Rex (56.3%) showed significantly higher (P<0.05) than New Zealand White (40.7%) and Californian (42.0% ). 4. P. multocida.(37.9%), B. brouchiseptica (16.0%), E. coli (10.6%) and so forth were isolated from 92 samples of lungs and nasal discharges. 5. Sixty fours trains of P. multocida were typed by serological or non-serological tests and their all serotypes were A type (62 strains) except 2 strains of untypable. 6. In antimicrobial sensitivity test for 64 isolates of P. multocida, all the strains tested were highly sensitive to chloramphenicol(95.3%), colistin (95.3%), gentamicin (92.2%), kanamycin (90.6%), neomycin (82.8%) and tetracycline (81.3%), but exhibited low sensitivity to streptomycin (26.6%), and all strains were resistant to lincomycin. 7 Twenty seven isolates of B. brouchiseptica showed higher sensitivity to cephalothin (100%), erythromycin (100% ), gentamicin (100%). trimethoprim+sulfamethoxazole (100%), chloramphenicol(88.9%), kanamycin(88.9%), neomycin (88.9%) and colistin (85.2%), but lower sensitivity to nitrofurantoin (18.5%), penicillin(18.5%). streptomycin(18.5%) and ampicillin (14.8%), and all strains were resistant to lincomycin.

  • Rhino-orbital-cerebral (ROC) mucormycosis is an uncommon, acute and aggressive fungal infection. It remains a challenging problem to clinicians despite aggressive debridement surgery and antifungal therapy. The authors describe a case of ROC mucormycosis with pericranial abscess occurring in a female patient with uncontrolled diabetes mellitus. The infection initially developed in the right-sided nasal sinus and later progressed through the paranasal sinuses with the invasion of the peri-orbital and frontotemporal region, due to the delayed diagnosis and treatment. Numerous non-septate hyphae of the zygomycetes were identified by a punch biopsy from the nasal cavity and by an open biopsy of the involved dura. The patient was treated successfully with extensive debridement of her necrotic skull and surrounding tissues, drainage of her pericranial abscess and antifungal therapy, including intravenous amphotericin B for 61 days and oral posaconazole for the following 26 days. She returned to a normal life and has had no recurrence since the end of her treatment 15 months ago.

  • The limited mouth opening, also known as trismus, can result from temporomandibular joint disorders, infection, neoplasm, trauma, and abnormal anatomic structure like coronoid hyperplasia. Head and neck cancer patients often complain of limited mouth opening, which is usually induced by myofibrotic contracture of masticatory muscle. But clinicians should consider any reasons such as infection or cancer growth and metastasis if trismus gets worse or pain develops. We report the case of the patient, who was diagnosed with myxofibrosarcoma on nasal cavity. He had suffered from trismus after concurrent chemoradiotherapy. However, pain had developed and trismus had worsened. He was diagnosed with infratemporal space abscess and myositis of masticatory muscles.

  • Purpose: Infection, foreign body reaction and decreased volume of implant are common complications after augmentation rhinoplasty with $Gore-tex^{(R)}$ implant. The author experienced two cases of recurrent foreign body granuloma in the patients who underwent $Gore-tex^{(R)}$ removal because of infection after augmentation rhinoplasty. and treated them with complete removal of$Gore-tex^{(R)}$. Methods: Case 1: A 49 year-old female visited our clinic for recurrent foreign body reaction on nasal dorsum and tip area. The patient underwent augmentation rhinoplasty with $Gore-tex^{(R)}$ 3 years ago and implant was removed due to infection 9 months ago. Excision of the granuloma was performed and a piece of foreign body suspicious to be a $Gore-tex^{(R)}$ implant debris was detected under the subcutaneous pocket. The implant fragments were removed and nasalis muscle rotation flap was performed to cover the lesion. The specimen was proved to be $Gore-tex^{(R)}$ in histological study. Case 2: A 31 year-old-male with recurrent foreign body granuloma on the nasal tip area visited our clinic. 10 years ago, the patient had augmentation rhinoplasty with silicone implant and then, he underwent revisional rhinoplasty five times including nasal implant removal, which was performed 9 months ago. The authors excised the granuloma and found a small sized foreign body suspicious to be a $Gore-tex^{(R)}$ implant debris under the granuloma. The foreign body was excised and identified to be $Gore-tex^{(R)}$ in histological study. Results: In both cases, the lesions were healed without any complications and there were no evidences of recurrence up to 6 months of follow-up. Conclusion: The $Gore-tex^{(R)}$ is known to be weak against mechanical force. These properties of $Gore-tex^{(R)}$ make it difficult to remove the implant completely. In the patient who have infection after augmentation rhinoplasty with $Gore-tex^{(R)}$, the operator should take care to perform the complete removal without remaining fragment of the implant.

  • 1. In oriental medicine, the case of sinusitis can be explained, not only external invasion such as PUNG HAN(wind-cold), PUNG YUL(wind-hot), SHUP YUL(damp-heat), but also functional disorder of internal organ such as spleen(脾), lung(肺), kidney(腎) The western medicine classified the cause of sinusitis as two factors. That is bacterial infection factor-Haemophilus influenza, streptococcus pyogeues, streptococcus pneumonia- and viral infection factor-Rhinovirus, parainfluenza, Echo28, Coxsacki21, Sinusitis is complicated to allergic rhinitis, chronic otitis media purulent, chronic tonsilitis, sinubronchitis. On the condition of nasal septum deformity, turbinates deformity, nasal septum deviation, sinusitis can be developed. the predisposing factors of sinusitis is swimming, air pollution, malnutrition, shortage of immunity.2. According to survey, sinusitis occurred that children from 4 to 12 years old and from 5 to 7 years old occupied 70% 3. From the past history data, they experienced chronic tonsillar hypertropy(20%), otitis media, atopic dermatitis, allergic rhinitis, bronchial asthma, pneumonia, bronchiolitis, chronic sore throat, urticaria, milk allergy in sequence. 4. the symptoms of sinusitis is nasal obstruction, postnasal dripping, purulunt(yellow)or white discharge, cough, nose bleeding in sequence. nasal obstruction take the portion of 95%, postnasal dripping 65%, night time or early morning cough 60%. 5. The suffering period of sinusitis is 6 month minimum, 4 years maximum, most cases are included in a year. The suffering period of children was shorter than adult. 6. Diagnosis depend on inspection of nasal cavity, postnasal dripping, X-ray finding. 75% of patient(15case) showed both maxillary sinusitis, 25%(5cases) showed left or right maxillary sinusitis. 7. Treatment of oriental medicine, consist of Herb-medicine, acupuncture and exposing of Lazer beam. Kamihyunggyeyungyotang(加味荊芥蓮翹湯) is administered mainly as the medical therapy, Kamigwaghyangjeungkisan(加味藿香正氣散) Kimizwakwieum(加味左歸飮), Kamihyangsosan(加味香蘇散) is administered for a additional symptoms which occurred by influenza recurrence. Kamijeonxibackchulsan(加味錢氏白朮散) is administered to treat gastro-intestine trouble patients who have sinusitis. 8. The period of treatment is varied with patient conditions and X-ray finding. The minimal period is 35days, maximal period is 202days. So it took about 86days in average and about 50% of patient(10cases) is recovered in one or two month.
