Purpose Haematogenous multifocal osteomyelitis in children represents a dangerous form of osteomyelitis in which sepsis can develop quickly if it is not treated early. A retrospective analysis of 26 children with acute multifocal haematogenous osteomyelitis over a period of 5 years was undertaken in order to assess the clinical presentation, infective organism, laboratory investigations and risk factors involved. Methods Children more than 1 year of age with two or more bones involvement presenting within one week from the onset of symptoms were included in this study. All of the children were evaluated by clinical examination, blood tests and local ultrasound. Results The average age at presentation was 4.9 years and girls were affected more than boys, with a female to male ratio of 1.4. Lower limbs were affected in 92% of cases, and, specifically, the tibia in 73.1% of the patients. Blood culture was positive in 38.5% of our cases. The predominant microorganism isolated from surgical samples was Staphylococcus aureus, among which methicillin-resistant S. aureus (MRSA) was found in 50% of the patients. Surgical drainage of the pus was done in 24 cases, followed by appropriate antibiotics, and two cases were treated by conservative means. All of the children were successfully treated except for four, who developed chronic osteomyelitis and sequelae. Conclusion We conclude that acute multifocal haematogenous osteomyelitis in children needs early diagnosis by a high index of clinical suspicion and adequate treatment with timely intervention. The predominance of MRSA in our study shows the changing trend in its association with multiple bone involvement.
Prematurity and anemia still appear to be important risk factors for neonatal septic arthritis. As there is changing trend toward gram-negative infections, attention has to be given toward preventing nosocomial and community-acquired infections. This is very important in premature infants who are susceptible for infection when they are kept in resuscitative units in hospitals.
Our study shows that age of the patient at presentation is critical as it shows significant reduction in knee score. This explains that the septic arthritis may contribute to the progression of age-related degeneration of the knee joint. There appears to be no definite contributing factors or conditions associated with acute hematogenous septic arthritis of the knee in adults, although further study may be warranted regarding this matter.
Calcific myonecrosis is a rare late complication of limb trauma characterized by liquefaction and dystrophic calcification of muscles in the single compartment, usually in the leg. This occurs many years after the trauma and is probably due to chronic compartment syndrome. We report 2 cases of calcific myonecrosis involving the anterior compartment of the leg that presented to us in an advanced stage of multiple sinuses discharging calcific material. Incision and drainage had been attempted at a local hospital prior to presentation at our hospital resulting in a non healing wound. Both patients had a history of antecedent trauma to the leg a few years ago. Patients were treated by thorough debridement of the involved muscles in the anterior compartment. Limited access dressing (LAD) was used to manage the dead space left after debridement. After application of the LAD, the wound was covered with split skin grafting. In both patients, healing of the cavity following debridement was facilitated by application of limited access dressing. While the wound completely healed, the disability due to extensive debridement of anterior compartment of the leg persisted. At the latest follow-up, the patients were asymptomatic without any recurrence. Thorough debridement of the compartment involved and application of LAD may be another option of treating calcific myonecrosis of the leg, which was initially considered a "do not touch" lesion. Morbidity due to surgery and need of repeated surgeries for recurrences should be kept in mind and regular follow-up should be considered.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
