최근 개발된 Teicoplanin은 glycopeptide계의 항생제로서 vancomycin과 그 작용 기전이 비슷하지만, 근육 주사가 가능하고, 반감기가 길어서 하루 한번 주사하여도 되며, 빨리 주입하더라도 red man syndrome이생기지 않는 장점이 있다. 이 연구의 목적은 그람 양성균에 의한 감염증을 치료하는데 teicoplanin이 효과적이고 안전한지를 vancomycin과 비교하는 것이다. 대상 환자 및 방법: 서울대학교병원에 입원하여 그람 양성균 감염증이 확인되거나 강력히 의심되는 환자를 대상으로 하였다. 감염증의 종류는 패혈증, 골수염, 하기도 감염증, 감염성 관절염, 피부 및 연조직 감염증, 요로 감염증으로 하였다. 대상 환자를 무작위로 teicoplanin또는 vancomycin군에 무작위 배정하였다. Teinoplanin은 처음에 loading을 위하여 400mg씩 12시간마다 3회 주사하고 이후에는 증증 감염이면 하루에 400mg, 중등중이면 200mg씩을 주사하였다. Vancomycin은 500mg을 6시간마다 또는 1. 0g을 12시간마다 정맥주사하였다. 치료 기간은 요로 감염증 5-10일, 하기도 감염증 5-10일, 패혈증 14-21일, 골수염 21-42일, 세균성 관절염 21-42일, 피부 및 연조직 감염증 5-10일로 하였다.

당뇨병환자에서의 감염증은 인슐린과 항균제의 사용으로 그 이환율과 사망률이 현저히 감소하였으나, 현재까지 당뇨병환자의 진료에 있어서 해결해야 할 중요한 문제로 남아있다. 당뇨병환자에서 감염증의 발생빈도는 대부분 일반인과 차이가 없다고 보고되고 있으나 일부 특정 감염증의 빈도는 현저하게 증가하고 감염증의 정도가 훨씬 심하며, 임상양상도 정상인과 다른 것으로 알려져 있다. 특히 인플루엔자, 세균뇨, 악성 외이도염, 비뇌모균증, 기종성 담낭염, 기종성 신우신염 또는 방광염, 급성 신유두괴사, 신주위 농양, 진균성 요로 감염증, 그람 음성균에 의한 폐렴, 괴사성 연조직 감염과 족부 궤양 관련 감염증 등은 당뇨병과의 관련성이 이미 입증된 감염질환들이다. 당뇨병 환자에서 감염증의 발생빈도는 약 14.4%에서 39.5%까지 보고되고 있으며, 국내에서는 폐결핵 20%, 요로 감염 20%, 폐렴 16%, 진균감염 7.6%, 균혈증 6.2%, 족부 궤양 관련 감염증 5.5%의 순으로 보고되고 있다. 당뇨병환자가 감염증에 대한 원인에 대해서는 확실히 밝혀지지는 않았지만 탈수, 영양실조, 다형 백혈구의 기능 장애, 혈액 순환장애 및 신경병증 등으로 설명되고 있다. 특히 당뇨병환자에서는 미세 혈관병증과 죽상경화증이 흔히 발생하기 때문에 각 조직으로의 혈액 공급이 감소되어 각 장기 조직에서는 정상적인 영양 및 산소 공급과 적절한 면역 반응을 유지하는 것이 어려워 결과적으로 감염증에 걸리기 쉽다. 이 글에서는 여러 가지 감염증 중 족부 궤양 감염증, 기종성 신우신염, 비대뇌모균증, 간농양에 대해 사례를 중심으로 알아보겠다.

Infections and inflammatory conditions of immature musculoskeletal systems in pediatric patients also affect the adjacent muscles, connective tissues, and joints. Rapid diagnosis leading to appropriate treatment can significantly impact the occurrence of complications and mortality rates due to these conditions. When a radiologist becomes familiar with the imaging findings of pediatric musculoskeletal infections and inflammatory diseases, rapid differential diagnoses and more timely and appropirate treatment could be possible. In this paper, we introduce the imaging findings of infectious and inflammatory diseases affecting the immature musculoskeletal system, such as osteomyelitis, pyogenic arthritis, juvenile idiopathic arthritis, and hemophilic arthritis, based on the anatomical and pathophysiological characteristics of the immature musculoskeletal system in children.

The definition of fascial spaces are latent spaces between fascial planes. If infections which spread from dental origin to soft tissue are mild, they are restricted by fascial planes. But, when infections are severe, fascial spaces are often used as a natural pathway which spread to the deep cervical region. If they are not treated at early stage, they may result in the fatal complications as followings; airway obstruction, septicemia, cerebral abscess, and thrombophlebitis etc. The early treatment of fascial space abscess is very important for young children. These case reports present the successful result of fascial space abscess treatment through intracanal drainage without surgical excision. It is proven that the treatment through intracanal drainage has some benefits to the surgical excision, which are as follows: 1) It is economic to the patients or their parents avoiding admission. 2) The treatment procedure is more simple. 3) Childrens can avoid the fearful environment.

Culture tests are very important in choosing the appropriate antibiotics for bacterial infections. In some cases, bacteria that could not be identified in standard culture bottles could be detected using blood culture bottles. A previously healthy 13-year-old boy visited our emergency room. He experienced pain, redness, and hardness of periumbilical skin and a fever for five days. There was no history of abdominal surgery and penetrating trauma. Computed tomography showed abscess with cellulitis at the periumbilical soft tissue with no congenital anomaly. Ultrasonography-guided aspiration was performed, and about 8.5 mL of the purulent abscess was aspirated. The abscess was cultured using blood culture bottle. The pus grew Actinomyces radingae and Clostridium ramosum. When performing the pus culture, using blood culture bottles can be more effective and rapid than the standard culture method for the detection of bacterial pathogens.

Staphylococcus aureus (SA) is a common cause of skin and soft tissue infections. Panton-Valentine leukocidin (PVL) toxin-producing strain of SA has been discovered worldwide and is known to cause serious infections. However, reports of neonatal infections caused by PVL-positive SA are rare. Here, we report a case of severe skin and soft tissue infection caused by PVL-positive SA in a 7-day-old neonate. The patient was admitted to the emergency room with a history of fever for one day, tenderness, and sensation of buttocks heating. The infant presented with fever, tachycardia, poor general health, progressive tenderness, and edema of the buttocks on the day of admission. Ultrasonography and magnetic resonance imaging revealed necrotizing fasciitis involving the skin, soft tissue, and muscles. Specimens drained from the buttock lesions confirmed the presence of PVL-positive methicillin-resistant SA (MRSA), and there was no bacteremia. She recovered after one month of intravenous antibiotics and surgical drainages. One month after discharge, she was rehospitalized for otitis externa and was infected with MRSA again. Considering the PVL-positive strain, the patient was treated with intravenous linezolid and dressing. The patient underwent decolonization therapy in a 0.5% chlorhexidine bath and recovered completely without sequelae. This case suggests that aggressive drainage and antibiotic treatment are essential for PVL-producing MRSA infections, and additional decolonization is needed to prevent recurrence and community spread.

Purpose : Staphylococcus aureus causes a variety of infections, ranging from benign skin infections to fatal invasive infections. Recently, methicillin-resistant S. aureus (MRSA) infections have emerged in patients who do not have established risk factors. This study was conducted to characterize S. aureus infections in children with an emphasis on communityassociated MRSA infections at a tertiary care pediatric facility during a 3-year period. Methods : Four hundred twenty-nine cases of S. aureus infections diagnosed at the Seoul National University Children's Hospital between January 2004 and December 2006 were retrospectively reviewed. The cases were classified as hospitalonset (HO) or community-onset (CO), healthcare-associated (HA), or community-associated (CA) infections. Results : Among the 206 cases <1 year of age, 72%, 7%, and 21% were HO-HA, CO-HA, and CA infections, respectively, as compared to 48%, 28%, and 24% among the 223 cases >1 year of age. The proportion of CO-HA infections among HA infections (8.6% vs. 37.1%, P<0.001) and the proportion of HA infections among the CO infections (24.5% vs. 54.3%, P <0.001) were greater in older children than in infants. Overall, 57% of the isolates were methicillin-resistant. Twenty-nine (30%) of 96 CA strains were MRSA, and the most common site of CA-MRSA infection was the skin and soft tissues (26 cases). Conclusion : The methicillin resistance rate of S. aureus from CA infections was high and CA-MRSA was most often associated with skin and soft tissue infections.

Necrotizing fasciitis is a rare, but life-threatening infection. Prompt diagnosis and early aggressive intervention is required for survival. However, there has been frequently occurred in delays of diagnosis and treatment due to its non-specific nature. Therefore, a high index of suspicion is needed to ensure timely intervention. We report a case of necrotizing fasciitis in a 7-day-old term healthy neonate.
