Claw lesion is one of the major causes of lameness in sows and the lameness is one of the reasons for culling of sows from the swine herd. This survey was conducted on sows in total of 8 farms with a total of 684 pigs. The lesions observed in the study were horizontal and vertical claw cracks (CWH & CWV), differences in the length of toes (T) and/or in the length of dew claws (DC) according to crates, breeds and parity of sows. Scores of claw lesions were assigned on 0, 1, 2, and 3 at each foot depending on the severity of the claw lesions. The sows' parity was classified into 1 to 2, 3 to 4, 5 to 8. Prevalence rate of claw lesions in sows raised on punched plastic crate was higher than that in sows raised on tribar crate. In prevlence rate by breeds, inbreed Landrace sows showed higher than that of Yorkshire sows. According to 4 claw lesions, the length of DC was the highest at parity 3~4 and CWV was the lowest at parity 3~4 in F1 crossbred sows raised on punched plastic crates, respectively. In Yorkshire breeds raised on punched plastic crates, the length of DC at parity 5~8 was the lowest and CWH was the highest at parity 3~4, respectively. In Landrace breeds raised on tribar crates, CWH was the highest at parity 1~2 and CWV was the lowest at parity 3~4, respectively. The high parity in F1 crossbred sows showed high prevalence rate of claw lesions than that of low parity and other inbreed sows, respectively. These results may be useful as elementary data in establishment of welfare quality protocol and preventive measures to reduce economic losses from craw lesions in sows.

A 2-year-old miniature poodle dog was referred to Seoul Animal Clinic for assessment of traumatic ocular lesion by cat claw. Corneal perforation accompanied by hyphema following iridal laceration was observed in the left eye. Topical antibiotics, mydriatics and systemic antibiotics/steroids were applied to treat severe uveitis with miosis and fibrinous exudate. Although lenticular lesion was explored after mydriasis, it was obscured by severe corneal edema around corneal perforation. Despite aggressive treatments, the uveitis became more serious in the next day. To prevent septic implantation syndrome from anterior lens capsule disruption, phacoemulsification surgery was performed. The anterior lens capsule disruption was detected during continuous curvilinear capsulorhexis. The left eye remained the vision with mild posterior capsule opacification and intermittent conjunctival hyperemia during seven-month follow-up.

Purpose: Toe ulcers have been implicated as a causative factor in diabetic foot amputation. The aim of this study was to evaluate the outcomes of percutaneous needle flexor tenotomies of diabetic claw toes with ulcers or pending ulcers. Materials and Methods: The authors undertook a retrospective chart review between January 2014 and June 2016 to identify those patients who underwent a percutaneous needle flexor tenotomy for diabetic claw toe deformities. We evaluated 54 toes in 42 patients. Twenty-four patients were female and the mean age at the time of operation was 57 years. The mean follow-up time was 11 months. Thirty-four patients (46 toes) had tip toe ulcers or pending ulcers and 8 patients (8 toes) had dorsal pending ulcers. All patients had palpable pulses and good capillary refill. Results: Forty-three of 46 tip toe ulcers (93.5%) healed without significant complications and 8 dorsal ulcers showed no specific changes within 5 weeks. There were no recurrent ulcers at final follow-up. Four patients developed transfer lesion of the adjacent toe and needed subsequent tenotomy. Conclusion: Percutaneous needle tenotomy in an outpatient clinic was an effective and safe method for treating toe ulcers in neuropathic patients to offload the tip of the toe so that ulcer healing could occur.

Plantar corn is a circumscribed and sharply demarcated hard mass of traumatic hyperkeratosis, which has a central core impacting the dermis deeply and causes pain while walking. The cause of the corn is the mechanical stress to the skin induced by several causative factors; extrinsic(tight shoes) or intrinsic(bony prominence), or combined(the claw toe). We found 7 cases of patients with a painful recurrent plantar corn which had an epidermal cyst under its lesion. These corns and cysts were excised totally and there was no recurrence in all cases during two to four months follow-up period. We think that an epidermal cyst may be another intrinsic factor for the development of a plantar corn. So, an epidermal cyst should be considered once in a recurrent plantar corn to be recalcitrant against popular treatments.
