Purpose: To demonstrate a training technique on the mammalian eye for optimum Cyanoacrylate Tissue adhesive application in cases of perforated corneal ulcers. Methods: A full-thickness defect simulating a perforation was created on the goat’s eye cornea to teach the technique of cyanoacrylate glue application in cases of corneal perforations to novice surgeons. Results: This training model on the mammalian eye was tested by 10 residents at our centre. All the 10 candidates involved in our series were newly joined Cornea fellows with proficient skill in cataract surgeries and minor ophthalmic procedures such as suture removal, chalazion excision, pterygium removal and administration of an intravitreal injection. None of the candidates had prior experience of corneal surgeries. Each resident made an average of 4.4 attempts to seal the corneal defect, obtain a regular corneal surface and form the anterior chamber. Conclusion: This training model helps in mastering one of the skills of corneal surgeries.

Abstract Domestic superglue (cyanoacrylate) in the hands of children can have devastating consequences, especially when cotton clothing is involved. When cotton comes into contact with cyanoacrylate, an intense exothermic reaction occurs, creating temperatures high enough to cause significant thermal injury. A literature review found 16 such cases of burns documented (2 adult and 14 pediatric). This article presents a case report of a 4-year-old child sustaining a full-thickness burn injury to her leg requiring skin grafting when superglue was spilt onto cotton pants. She was sitting near a fan heater at the time. An experiment was conducted to replicate the exothermic reaction between superglue and cotton and to determine if the addition of radiant heat would have any significant effect. The maximum temperature reached with one 3-g tube of superglue onto cotton pyjamas was 91°C (196°F) and occurred approximately 90 seconds postapplication. It took more than 3 minutes for the temperature to cool below 40°C (104°F). The addition of radiant heat from a fan heater placed 60 cm from the clothing found that the temperature peak was similarly reached and cooled, but the temperature did not reduce below 52°C (126°F) for over 20 minutes, proving that potential harm may be amplified if first aid is not appropriately sought. Product labeling and the knowledge of potential harm from such mechanism of injury remain inadequate. It is hoped that the reporting of this case contributes to an increase in public education and awareness of such dangers and may contribute to preventing avoidable future incidences.

Adhesive Application

A 10-year-old boy treated for alkali injury with multiple interventions presented with a perforated corneal ulcer with clinically suspected bacterial aetiology. Cornea scraping and tissue adhesive application were planned. During surgery, an eyelash was found embedded at the perforated site. Gram staining of corneal scraping revealed the presence of Gram-positive bacilli on the first day which later was identified as Turicella otitidis with culture followed by VITEK V.2.0 (Biomerieux) identification. The bacterium was found to be sensitive to amikacin, ciprofloxacin, cefazolin, gatifloxacin, moxifloxacin, ofloxacin and vancomycin antibiotics as per Clinical and Laboratory Standards Institute guidelines. Coryneform bacteria is a rare cause of keratitis, and this is the first reported case of microbial keratitis caused by one of the rare corynebacterium species T. otitidis to the best of our knowledge. Literature search does not reveal any specific ocular features typical to this organism. This case supports the growing evidence for pathogenicity of T. otitidis in ocular samples. This study demonstrates the utility of VITEK for the identification of rare pathogen and may facilitate the use of certain antibiotics in the treatment regimen of T. otitidis infections.

Nonaccidental Injury

Three children with burn injuries caused by home hair dryers are described. In one patient the injury was believed to be accidental, and in the other two cases the injuries were deliberately caused by a caretaker. The lack of prior experience with hair dryer burns initially led to suspicion of other causes. The characteristics of each case aided in the final determination of accidental vs nonaccidental injury. These cases prompted testing of home hair dryers to determine their heat output. At the highest heat settings, the dryers rapidly generated temperatures in excess of 110°C. After the dryers were turned off, the protective grills maintained sufficient temperatures to cause full-thickness burns for up to 2 minutes. These cases and the results of testing demonstrate that hair dryers must be added to the list of known causes of accidental and nonaccidental burns in children.
