Staged curative treatment of a complex direct carotid-cavernous fistula with a large arterial defect and an 'oversized' internal carotid artery

This is a case of a high-flow, post-traumatic direct carotid-cavernous fistula with a widened arterial defect and a large-diameter internal carotid artery (ICA). The unique aspect of this case is the oversized ICA, >8mm in diameter, which is both a pathological and a therapeutic challenge, given the lack of available neuroendovascular devices for full vessel reconstruction. We present a planned two-stage embolisation paradigm for definitive treatment. Transarterial coil embolisation is performed as the first stage to disconnect the fistula and normalise flow in the ICA. A 3-month recovery period is then allowed for reduction in carotid diameter. Repair of the large vessel defect and pseudoaneurysm is performed as a second stage in a delayed fashion with a flow-diverting device. Follow-up angiography at 6 months demonstrates obliteration of the fistula and curative ICA reconstruction to a diameter <5mm.

Antibiotic-associated haemorrhagic colitis: not always Clostridium difficile

Antibiotic-associated colitis is a gastrointestinal complication of antibiotic use commonly seen in hospitalised patients, with Clostridium difficile (C. difficile) colitis being the most common type. We present a case of haemorrhagic colitis secondary to Klebsiella oxytoca following self-initiated amoxicillin–clavulanic acid use. An 85-year-old woman presented to the emergency department with abdominal pain and mucobloody diarrhoea. History was notable for an ongoing 5-day course of amoxicillin–clavulanic acid use. The CT scan of her abdomen revealed extensive diffuse thickening of the ascending and transverse colon. Stool culture grew K. oxytoca, an established cause of haemorrhagic colitis. She declined colonoscopy but recovered with withdrawal of all antibiotics and conservative treatment. We should be vigilant to haemorrhagic colitis following antibiotic use which is not always C. difficile related.

Marjolins squamous cell carcinoma of the hallux following recurrent ingrown toenail infections

Marjolin's squamous cell carcinoma (SCC) affecting the toe is rare. Due to resemblance with benign conditions it can often result in misdiagnosis. We report a case of Marjolin's SCC affecting the proximal hallux in a patient with recurrent ingrown toenail infections. A 58-year-old woman with a background of wedge resections for ingrown toenail and distal phalanx amputation for osteomyelitis presented with pain and hyperkeratotic raised ulcer around the proximal phalanx. MRI scan revealed soft tissue mass infiltrating the proximal phalanx with biopsies confirming a SCC. The patient underwent first ray amputation and made a good clinical recovery and remains disease free. Due to clinical similarities with benign conditions, awareness of Marjolin's SCC as a potential diagnosis when treating patients with recurrent ingrown toenail is imperative. We recommend patients with recurrent ingrown toenail or ulceration with a background of chronic infection have biopsies performed to exclude potential malignancy.

Infectious crystalline keratopathy after Descemeta{euro}™s stripping endothelial keratoplasty

A 68-year-old woman presented with infectious crystalline keratopathy 4 months after she underwent a combined phacoemulsification and Descemet's stripping endothelial keratoplasty for Fuch's endothelial dystrophy in her left eye. After 5 months of topical moxifloxacin 1%, the infiltrate responded well but had not completely resolved, with the resulting endothelial failure requiring a penetrating keratoplasty 9 months after the initial operation. Microbiology identified Enterococcus faecalis with the histopathology demonstrating bacterial colonies within the graft interface. Postoperatively she developed endophthalmitis, needing vitrectomy and intravitreal antibiotics. The infection settled with no recurrence, with topical and oral antibiotics continued for 2 months. A sutured toric piggyback intraocular lens was performed 18 months postvitrectomy for graft astigmatism, achieving a best-corrected vision of 6/15.

Infectious crystalline keratopathy can occur following Descemet's stripping endothelial keratoplasty, requiring long-term topical therapy and potentially leading to graft failure with the necessity for further keratoplasty.

Twenty-nine-month follow-up of a paediatric zirconia dental crown

The aim of this paper is to present the long-term follow-up of one paediatric zirconia crown on a deciduous molar. Preformed crowns are part of the armamentarium in paediatric dentistry. In recent years, aesthetic alternatives to preformed metal crowns have been developed, first preveneered crowns and then zirconia crowns. This paper describes the restoration of a primary molar with a zirconia crown (EZ-Pedo, Loomis, California, USA) in an 8-year-old boy. In this clinical case, the protocol for the implementation and maintenance of zirconia crowns is detailed. The patient was followed up for 29 months until the natural exfoliation of his primary molar. The adaptation of the zirconia crown, the gingival health and the wear on the opposing tooth were considered. In this case, the paediatric zirconia crown allowed sustainable functional restoration while restoring a natural appearance of the tooth.
