ABSTRACT
BACKGROUND: Silver nitrate cauterisation is the conventional treatment for peritoneal dialysis catheter exit-site granulomas. However, it requires to be performed by nurses, patients often experience pain and chemical burns. Therefore, the appropriateness and applicability of using 2% aqueous chlorhexidine swabstick as an alternative was explored in two nephrology centres in Hong Kong. OBJECTIVE: To examine possibility of conducting full trial using chlorhexidine swabstick compared with silver nitrate. DESIGN: A pilot study. PARTICIPANTS: Fort-four patients with exit-site granulomas were equally, randomly allocated to receive chlorhexidine swabstick or silver nitrate. MEASUREMENTS: Both groups were followed for 6 weeks to evaluate the time of granuloma subsidence and adverse effects. Pain and treatment satisfaction were assessed using numerical rating scale and self-developed questionnaire, respectively. RESULTS: Healing rates were 94.4% (17 of 18) using chlorhexidine swabstick,100% (21 of 21) using silver nitrate (p = 0.46). The mean time of granuloma subsidence was significantly longer when using chlorhexidine swabstick (32.8 days) than silver nitrate (12.3 days, p=0.02). The chlorhexidine swabstick group reported significantly fewer adverse effects (11.1%, 2 of 18, p = 0.01) compared with the silver nitrate group (52.4%, 11 of 21). The chlorhexidine swabstick group had lower mean pain score (0.5 of 11) than the silver nitrate group (2.4 of 11, p < 0.01). The satisfaction scores between the two groups had no substantial difference. CONCLUSION: Chlorhexidine swabstick took long time to remove granulomas but had similar success rate, less pain, fewer adverse effects than silver nitrate. Additional research is warranted to examine the applicability of chlorhexidine swabstick.

BACKGROUND: Aluminum contact allergy is mostly seen in children with vaccination granulomas, following immunization with aluminum-adsorbed childhood vaccines. OBJECTIVES: To characterize a cohort of children with vaccination granulomas and aluminum allergy concerning early life conditions, exacerbating factors, avoidance behavior, treatments, and potential impact on quality of life. METHODS: A questionnaire study was conducted among 177 children aged 0 to 15 years with vaccination granulomas and aluminum allergy, and a reference group of 61 children aged 3 to 14 years with various types of dermatitis undergoing patch testing. RESULTS: All children in the granuloma group were reportedly affected by itch. Infection exacerbated the itch in 59%. Other worsening factors were eating tin-foiled/canned food (31%) and use of aluminum-containing sunscreen (46%). Many parents took precautions to avoid aluminum exposure. Children with granulomas were more likely to be nonadherent to the National Vaccination Program than the reference group (27% vs 2%, P < .001). Parents in the granuloma group reported a decreased life quality for both parents and children compared with the reference group. CONCLUSIONS: Itching vaccination granulomas and aluminum allergy have a considerable negative impact on affected children and their families, causing avoidance behavior, reduced adherence to vaccination programs, and a negative effect on the overall life quality.

We present the first case of a 57 year old man who developed severe, acute vasospasm following transcallosal resection of an unusual, xanthogranulomatous colloid cyst. The 16 year history of growth of this cyst may have resulted in its unusual pathology, and the subsequent vasospastic reaction to its excision. We discuss the potential pathological relationship between the inflammatory nature of the cyst, chemical meningitis and vasospasm, and what this implies about vasospasm in general. The severe, life-threatening vasospasm affected all four major vessels and required aggressive management by endovascular injection of nimodipine and angioplasty, with good recovery. The case illustrates a previously undescribed sequel of surgery for this condition, demonstrates an effective treatment and offers possible insights into the pathogenesis of vasospasm.
