Incidence of periorbital necrotising fasciitis in the UK population: a BOSU study.

BACKGROUND: Periorbital necrotising fasciitis (PNF) is a devastating infection of subcutaneous soft tissue and underlying fascia causing severe morbidity and even loss of life. Few case reports of PNF exist and there are no prospective epidemiological studies. METHODS: A prospective observational study was undertaken using the British Ophthalmological Surveillance Unit reporting system. Questionnaires were sent to reporting ophthalmologists in the UK seeking cases of PNF over a 2-year period. RESULTS: 30 new cases were confirmed. 16 of the reported cases followed a precipitating event, 9 cases followed trauma and 3 followed surgery. ß-haemolytic Streptococcus A was the causative organism identified in 76%, either alone or with concurrent infection, and antibiotic sensitivities are discussed. Systemic complications occurred in the majority of cases (66.6%), with sepsis and death occurring in 10%. Over 50% of surviving patients had subsequent morbidity, reduced acuity (<6/18) being common. CONCLUSION: PNF is a rare, dangerous condition. This study identified an incidence of 0.24 per 1,000,000 per annum in the UK. ß-haemolytic Streptococcus A is the most common causative organism. Mortality remains a potential outcome, and survivors suffer significant morbidity. Early intravenous antibiotic management with a consensus favouring penicillin and clindamycin combined with debridement.

Intravitreal bevacizumab for the treatment of retinopathy of prematurity: a case report.

OBJECTIVE: We report the first case in Scotland of a premature infant treated for retinopathy of prematurity with bevacizumab. METHOD: A case report and a review of the literature are presented. RESULTS: Retinopathy of prematurity is a leading worldwide cause of childhood blindness. Conventional laser treatment results in destruction of the peripheral retina and does not prevent all cases of vision loss, particularly in Zone I disease. We present the case of a baby born at 26(+3) weeks who developed stage 3+ disease located in Zone I of the retina. The patient was treated with bilateral bevacizumab injections and achieved complete resolution of his retinopathy. CONCLUSION: Bevacizumab therapy for the treatment of retinopathy of prematurity is an effective and inexpensive treatment that can readily and quickly be administered by a competent ophthalmologist without the need for specialist equipment.

Neuroendocrine carcinoma of the ethmoid sinuses treated with radiotherapy alone.

OBJECTIVE: We present the first report of a case of neuroendocrine carcinoma of the paranasal sinuses treated successfully with radiotherapy alone. METHOD: A case report and literature review are presented. RESULTS: Fewer than 50 cases of paranasal sinus neuroendocrine carcinoma have been reported. We present an 82-year-old man referred with recurrent epistaxis. He was investigated by biopsy, computed tomography and magnetic resonance imaging, and was found to have a rare neuroendocrine carcinoma. He declined any surgery or chemotherapy but consented to radiotherapy. Thirty months later, he remained clinically free from cancer. CONCLUSION: There is no consensus for the management of paranasal sinus neuroendocrine carcinoma. Most cases are treated with surgery with or without chemoradiotherapy. This case shows that radiotherapy alone may be a viable treatment option for some cases.

Lower limb activity and its determinants in COPD.

BACKGROUND: Patients with chronic obstructive pulmonary disease (COPD) walk less than healthy older people and their self-reported activity predicts exacerbation risk. The relationship between lower limb activity and total daily activity is not known, nor are there any data which relate objectively assessed daily activity to laboratory assessments made before and after rehabilitation. METHODS: Lower limb activity was measured by leg actigraphy over 3 days in 45 patients with moderate to severe COPD and 18 controls of similar age. Thirty-three patients with COPD entered an 8-week rehabilitation programme in which the change in leg activity was measured and related to other outcomes. RESULTS: In patients with COPD the mean level of activity measured by whole body and leg activity monitors was closely related (r = 0.92; p<0.001), but leg activity was consistently reduced compared with controls of similar age (p = 0.001). Mean leg activity, mean intensity of leg activity and the time that patients spent mobile at home were all related to forced expiratory volume in 1 s (FEV(1)) (r = 0.57, p = 0.001; r = 0.5, p = 0.003; and r = 0.51, p = 0.002, respectively), but intensity of activity and time spent mobile were not related. Subjects completing pulmonary rehabilitation showed significant improvements in mean activity (p = 0.001) and spent more time moving (p = 0.014). These changes were unrelated to improvement in muscle strength or walking distance but correlated with baseline FEV(1) (r = 0.8, p<0.001). CONCLUSIONS: Total daily activity in patients with COPD is closely related to leg activity which is reduced compared with controls of similar age. Individuals differ in the time spent mobile during the day, but subjective and objectively assessed activity improves after rehabilitation and is predicted by FEV(1). The change in activity is unrelated to improvements in corridor walking and health status.
