Abstract
Neonatal septic arthritis and osteomyelitis is not prevalent in first month of the life in new borne children. According to anatomic specifications of bones in this period, the manifestation of disease is different from other periods of life and the disability induced, will be serious and permanent. In this investigation, 31 infants with the diagnosis of septic arthritis and osteomyelitis were studied during 10 years. Hyperbilirubinemia (58.1 percent), emergency cesarean (25.8 percent), umbilical vessel catheterization (26.6 percent), permaturity (12.9 percent), perinatal asphyxia (9.7 percent), scalp laceration (6.5 percent), omphalitis & previous bone fracture (6.5 percent) were the most common findings among predisposing factors. Previous hospital admission was detected in 19 patients (67.3 percent) and multiple bone involvements demonstrated in 12 (38.7 percent). From those who had risk factors, 42.3 percent had multiple bone lesions. Only 5 patients (16.12 percent) had no predisposing factors. The mean age for diagnosis and seeking admission were 23 and 30 days respectively and the mean age of diagnosis at surgery was over 72 hours in 15 (48.38 percent) cases. All with delaying in requesting admission had destructive changes in their joints. Knee and hip were most involved (77.3 percent). The most common microorganisms found in this study were staphylococcus aureus and klebsiella. Of all, 47 percent were gram negative & 53 percent gram positive microorganisms. Existence of risk factors and previous hospital admission in the majority of cases accompanied by microorganisms such as methiciline resistant S.aureus and klebsiella as a causative agents who were also resistant to empirical antibiotics demonstrated the role of nosocomial infections as an important cause of infection.

Abstract
Background: Septic arthritis in neonates can be difficult to diagnose and may be associated with severe morbidity and even mortality. A majority of apparent septic arthritis cases may have a negative culture, thereby creating a dilemma regarding treatment. The present study investigates demographic, laboratory and clinical variables of septic arthritis in neonates hospitalized over a period of 17 years.
Methods: The medical files of all neonates hospitalized in Imam Khomeini and Vali-e-Asr Hospitals in Tehran, Iran, from 1989 to 2005 were assessed and the files of 59 neonates with a diagnosis of septic arthritis were further evaluated. Variables such as age, sex, gestational age, birth weight, history of hospitalization, body temperature, involved joints, blood and joint fluid cultures, ESR, CRP, and WBC count were evaluated in this group of hospitalized patients.
Results: Of the 59 neonates, 39 cases were male and 20 cases were female. At the time of hospitalization, 45.8% of the neonates were 20-28 days old and 52.2% were 10-20 days old, and 67.7% and 35.6% of cases had been preterm and had low birth weight, respectively. Histories of hospital admission were found for 30.5% of patients. The two most common joints involved were hip (30.5%) and knee (23.72%). The mean body temperature was 36.6oC. ESR was elevated in all patients (mean 85 mm/h) and CRP was positive in all cases. The WBC count was >15,000/mm3 in 39% of the neonates and was in the range of 10,000-15,000/mm3 for 47.4%. Blood and joint fluid cultures were positive in 51% and 91.5% of cases, respectively. The organisms isolated from joint fluid culture were Klebsiella (54%), S. aureus (37%) and E. coli (9%).
Conclusion: Due to the rarity of septic arthritis in neonates and paucity of signs and symptoms, all neonates with a high index of suspicion should be examined carefully with septic arthritis in mind.

Abstract
Background : Septic Arthritis is an acute infection of intra-arthicular space. Delay in diagnosis and in appropriate treatment may lead to prolongation of treatment duration and poor outcome. We decided to evaluate clinical aspects of this disease in our department pediatric department, Imam Khomeini Hospital complex, Tehran, Iran during a 10 years period.
Methods : In a retrospective cross-sectional study, 60 patients with age from 1 month to 14 year-old during 1996-2005 were evaluated. The demographics characteristics, clinical observations (signs & symptoms) and paraclinic values were gathered from medical records and analyzed with statistical tests.
Results : Pain and Swelling was seen in all, joint limited motion in 80% ( 50 cases) claudicating in 64% ( 38 cases), fever in 80% ( 48 cases), monoarticular disease in 80% ( 48 cases) and polyarticular one in 20% ( 12 cases) of them. Hip was most Common involved joint 62% ( 37 cases), elevated ESR was seen in all patients. CRP was positive in 85% ( 51 cases). Leuckocytosis was found in 65/8% ( 17 cases) of cases. In infectious cases, Staphylococcus aurous was responsible organism in 65.6% ( 16 cases), klebsiella in 12.4% ( 3 cases), Streptococcus pneumonia in 12.3% ( 3 cases), group b streptococcus in 4.1% ( 1 case), Hemophilus Influenza type b in 4.1% ( 1 case) of study patients. With therapy ESR was normalized in 64% ( 39 cases) and CRP was normalized in all patients.
Conclusions: In general, all children with complaint of fever, pain, and limited joint motion or claudicating should be suspected for septic arthritis.

Abstract
Background: Determining the etiologic causes of septic arthritis is of the most importance. Goal of this study was to investigate presence of staphylococcal enterotoxins A, B, C and Toxic Shock Staphylococcal toxin-1 in the synovial fluid of patients with arthritis.
Methods: This cross-sectional study was performed in the Pediatric and Orthopedic Wards of Hazrat Rasoul Hospital in Tehran, Iran during 2008- 2010. Gram stains, conventional cultures, direct detection of soluble bacterial antigens were used to detect H. influenza, S. pneumonia, group B streptococci, and N. meningitidis while Latex particle agglutination test was used for staphylococcal supper antigens (by enzyme immunoassays) upon synovial fluid tapping of 62 individuals (5 mo to 16 yrs, mean=113.8 yrs). P<0.05 was considered statistically significant.
Results: Positive SF cultures (n=11): 5 positive cases of S. aureus 5 S. pneumonia 1 H. influenza, and 1 Klebsiella. Positive gram stains: 10% and positive LPA: 4%. Staphylococcal arthritis was diagnosed in 7 (39%) cases upon positive culture or positive gram stain. The most common type was TSST-1 (47%) and the least common was enterotoxin B (18%). Isolation of S. aureus (positive culture) was correlated to presence of enterotoxin A in synovial fluid but not to enterotoxins B, C or TSST-1.
Conclusion: Staph. aureus had a prominent role in arthritis. 47% of cases with negative culture for S. aureus had at least one type of staphylococcal super antigens in the synovial fluid. Searching for antigens of usual organisms or staphylococcal supper antigens could be helpful for diagnosis and
