Abstract:
Objective To study the clinical and imaging features of neonatal acute osteomyelitis.Method From 2011 to 2016,the clinical feature,laboratory results,pathogen,imaging features,treatment and prognosis of neonates who were diagnosed with acute osteomyelitis in NICU of People's Hospital of Xinjiang Uygur Autonomous Region were retrospectively studied.Result A total of 13 cases were enrolled during the study period,5 males and 8 females,with onset age of 7 ～30 d.8 cases had different degrees of fever and 5 of them showed dyspnea;8 cases had elevated skin temperature and swelling at the affected area;7 cases presented with irritability;6 cases had anorexia;all cases had elevated white blood cell count.Blood culture were taken immediately after their admission,and culture from the pus were taken for some patients.5 cases had positive blood culture and Staphylococcus aureus was the main pathogen.6 cases had positive pus culture,and 4 cases showed gram positive (G +) bacteria and 2 cases gram negative (G-) bacteria.Humerus and tibia were the main foci of the infection.4 cases had X-ray examination within 7 days of onset showing soft tissue swelling and no sign of bone destruction.13 cases had X-ray examination at 7 to 14 days of disease.Among them only 1 case showed soft tissue swelling,and the rest 12 cases had different levels of bone destruction and periosteal reaction.2 cases had X-ray examination after 14 days of disease,showing stiffening ring,inflammatory changes and periosteal reaction.All patients were treated with broad-spectrum antibiotics after admission,and the affected limbs were immobilized.3 cases had further surgical treatment.11 patients recovered and were discharged,1 patient was treated at local hospital after diagnosis and 1 patient refused further treatment due to serious complications after 35 d of hospital stay and was lost on follow-up.Conclusion The clinical manifestation of neonatal osteomyelitis is atypical,the radiological and pathogen examination should be carried out once osteomyelitis is suspected.Appropriate antibiotics and timely surgery can prevent further damage and long-term sequela.
