STAPHYLOCOCCAL SCALDED SKIN SYNDROME: RETROSPECTIVE ANALYSIS OF 82 CASES

Objective To explore distinctive clinical manifestations and appropriate treatment, and assess prognosis of staphylococcal scalded skin syndrome （SSSS）. Methods A retrospective analysis was conducted of the data of 82 cases of SSSS hospitalized at Xinhua Hospital during the period from May 1993 to September 2003. Results The disease in all the 82 patients occurred in their first decade （mean 2.5 years）. Possible predisposing factors were found in 48 （58. 5% ）. Fever was present in 78 （95. 1% ）. Radial spokes of crusting around mouth were present in 80 （ 97. 6% ）. Erythema began on the face, especially around the mouth and eye in 63 （ 76. 8% ）. The course was acute in all cases and the eruptions quickly spread to the whole body within one day to two days. Of the 82 cases of SSSS, 47 were complete form of SSSS, 27 were abortive form of SSSS, and 8 were between the two forms. Staphylococcus aureus with positive staphylocoagulase was isolated from the possible primary infection sites including pharynx, eyelid, conjunctiva, nose, ear, and skin in 18 of 31 patients. Microbiological cultures of bullae and little pustulae developed after the onset were negative in 16 cases. All the 82 patients completely recovered after receiving antibiotic therapy （ ceftriaxone, oxacillin） alone or in combination with human immunoglobulin （IVIG） therapy. Additional IVIG therapy was used in those patients who had systemic involvements such as pneumonia, fever higher than 38. 5℃ or leukocytosis. Conclusion SSSS is a spectrum disease. Besides abortive and complete forms, presenting between the two forms a new form might be appeared in 8 cases who developed both scarlatiniform rash and flaccid bullae. The abortive form and complete form are usually misdiagnosed clinically. Radial spokes of crusting around mouth seem to be characteristic manifestation of SSSS. All the patients in this study had favorable prognosis after receiving prompt diagnosis and appropriate treatment.

Neonatal Staphylococcal Scalded Skin Syndrome:A Case Report

Objective:To summarize the clinical features,diagnosis,and treatment of neonatal staphylococcal scalded skin syndrome(SSSS).Methods:The clinical data with SSSS was analyzed,and the related literature was reviewed.Results:The acute onset of the disease was characterized by generalized erythema,epidermis exfoliation,skin non-touch,radial chapping around the mouth,and positive Nissl sign.The culture of binocular secretions and neck exudates showed Staphylococcus aureus and was diagnosed as SSSS.According to the results of drug sensitivity of secretions and exudates,vancomycin was selected for anti-infective treatment,and skincare and symptomatic support were given simultaneously.The child was cured and discharged after ten days of treatment.Conclusion:SSSS belongs to neonatal acute and critical illness.Improving etiological examination and timely targeted anti-infective treatment is the key to correct diagnosis and recovery.

Antiaging activity of low molecular weight peptide from Paphia undulate

Low molecular weight peptide (LMWP) was prepared from clam Paphia undulate and its antiaging effect on D-galactose-induced acute aging in rats, aged Kunming mice, ultraviolet-exposed rats, and thermally injured rats was investigated. P. undulate flesh was homogenized and digested using papain under optimal conditions, then subjected to Sephadex G-25 chromatography to isolate the LMWP. Administration of LMWP significantly reversed D-galactose-induced oxidative stress by increasing the activities of glutathione peroxidase (GPx) and catalase (CAT), and by decreasing the level of malondialdehyde (MDA). This process was accompanied by increased collagen synthesis. The LMWP prevented photoaging and promoted dermis recovery and remission of elastic fiber hyperplasia. Furthermore, treatment with the LMWP helped to regenerate elastic fibers and the collagen network, increased superoxide dismutase (SOD) in the serum and significantly decreased MDA. Thermal scald-induced inflammation and edema were also relieved by the LWMP, while wound healing in skin was promoted. These results suggest that the LMWP from P. undulate could serve as a new antiaging substance in cosmetics.
