Streptococcal infection and necrotizing fasciitis—implications for rehabilitation: a report of 5 cases and review of the literature

Cervical Necrotizing Fasciitis: A Potentially Fatal Disease with Varied Etiology

Necrotizing fasciitis was recognized centuries ago by physicians. It is a rapidly progressive and potentially fatal soft-tissue infection that is typified by soft-tissue necrosis, especially affecting the subcutaneous tissues and fascia. Cervico-facial necrotizing fasciitis is said to be uncommon, but when it occurs, it is often of odontogenic origin and has severe consequences if not promptly treated. Possible underlying systemic diseases and the source of infection should be addressed and treated appropriately. We present two cases of extensive cervicofacial necrotizing fasciitis, one of which was idiopathic in origin and the other with gross involvement of the chest and abdominal walls. Both were treated successfully. Immediate resuscitation of the patients, administration of empirical antibiotics, treatment of underlying systemic conditions and early, aggressive and serial debridement were the bedrock of management in these cases.

Oral health issues in the nutrition of institutionalized elders

Oral health is critical to systemic health and quality of life for the elderly, especially the institutionalized elderly, who are at high risk for oral and nutritional problems. Oral health is an integral component of overall nutritional health, just as nutrition plays a vital role in overall oral health. This article reviews the critical factors in the relationship among oral, nutritional, and systemic health and urges ongoing collaboration of providers of health care to reduce the rate of morbidity and mortality in institutionalized elders.

Treatment for diabetic foot ulcers

People with diabetes develop foot ulcers because of neuropathy (sensory, motor, and autonomic deficits), ischaemia, or both. The initiating injury may be from acute mechanical or thermal trauma or from repetitively or continuously applied mechanical stress. Patients with clinically significant limb ischaemia should be assessed by a vascular surgeon to determine the need for angioplasty, stenting, or femorodistal bypass. When infection complicates a foot ulcer, the combination can be limb or life-threatening. Infection is defined clinically, but wound cultures reveal the causative pathogens. Tissue specimens are strongly preferred to wound swabs for wound cultures. Antimicrobial therapy should be guided by culture results, and should aim to cure the infection, not to heal the wound. Alleviation of the mechanical load on ulcers (off-loading) should always be a part of treatment. Neuropathic ulcers typically heal in 6 weeks with total contact casting, because it effectively relieves pressure at the ulcer site and enforces patient compliance. The success of other approaches to off-loading similarly depends on the patients' adherence to the effectiveness of pressure relief. Surgery to heal ulcers and prevent recurrence can include tenotomy, tendon lengthening, reconstruction, or removal of bony prominences. However, these procedures may result in secondary ulceration and other complications. Ulcer recurrence rates are high, but appropriate education for patients, the provision of posthealing footwear, and regular foot care can reduce rates of re-ulceration.
