ReviewConservative Surgery of Diabetic Forefoot Osteomyelitis: How Can I Operate on This Patient Without Amputation?
Surgery is necessary in many cases of diabetic foot osteomyelitis. The decision to undertake surgery should be based on the clinical presentation of diabetic foot osteomyelitis. Surgery is required when the bone is protruding through the ulcer, there is extensive bone destruction seen on x-ray or progressive bone damage on sequential x-ray while undergoing antibiotic treatment, the soft tissue envelope is destroyed, and there is gangrene or spreading soft tissue infection. ⋯ Attempting conservative surgery in such cases risks infected tissues remaining in the wound bed leading to failure. The election of different surgical options depends on the expertise of the surgeons selected for the multidisciplinary teams. It is the aim of this article to provide a sample of surgical techniques in order to remove the bone infection from the forefoot while avoiding amputations.

Comparative StudyLipid-colloid dressing shows improved reepithelialization, pain relief, and corneal barrier function in split-thickness skin-graft donor wound healing.
Donor-site wound healing was tested with a nonadherent petrolatum- and hydrocolloid-impregnated polyester, a lipid-colloid dressing, and a nonadherent polyester dressing, supplemented with petrolatum manually by a physician onsite. Ten patients, 1 woman and 9 men (22 to 79 years old; average 58.4 ± 17.54 years), were enrolled in this prospective comparison study. The split-thickness skin graft was 14.5 ± 7.49 cm long × 8.2 ± 4.07 cm wide (5.5-27 cm long and 4.0-14.0 wide) and 14/1000 inches (0.356 mm) deep. ⋯ In moisture meter analyses, the values of effective contact coefficient and corneal thickness in lipid-colloid at wound healing was significantly smaller than those in polyester mesh (effective contact coefficient: 11.7 ± 1.87% and 15.6 ± 3.09% for lipid-colloid and polyester mesh, respectively, P < .05; corneal thickness: 31.1 ± 6.65 µm and 40.7 ± 8.69 µm for lipid-colloid and polyester mesh, respectively, P < .05). No significant difference was observed at 1 month after healing. The nonadherent lipid-colloid polyester dressing has superior wound healing and pain relief and demonstrates better corneal barrier function delineated by effective contact coefficient and corneal thickness at healing in split-thickness donors.

Management of a Patient With Faciocervical Burns and Inhalational Injury Due to Hydrofluoric Acid Exposure.
Hydrofluoric acid, a highly dangerous substance, can cause tissue damage and systemic toxicity by its unique mechanisms. Many cases of severe faciocervical burns due to hydrofluoric acid exposure are lethal. ⋯ This case highlights the extreme complexity of managing this kind of injury. Timely and accurate wound treatment and respiratory tract care, as well as active systematic support treatment, played vital roles in the management of this patient.

Clinical characteristics and risk factors of diabetic foot ulcer with multidrug-resistant organism infection.
The objective was to determine multidrug-resistant organisms' (MDROs) profile in diabetic foot ulcers (DFU), antibiotic resistance of MDROs, and to find the potential risk factors for infection with MDROs. In 157 patients with DFU admitted to Tianjin Metabolic Disease Hospital, China, from January 2011 to January 2012, microbiological specimens were taken on admission. The patients were divided into 2 groups according to the infection of MDROs. ⋯ Gram-negative MDROs showed 23% to 50% resistance to third-generation cephalosporins. The resistant rates of Gram-positive MDROs to fluoroquinolone were more than 70%; penicillin and semisynthetic penicillin were 57% to 100% resistant. Previous hospitalization (odds ratio [OR] = 3.000; 95% confidence interval [CI] = 1.100-8.182; P = .032), previous duration of antibiotic therapy (OR = 1.078; 95% CI = 1.001-1.160; P = .046), ulcer type (OR = 7.185; 95% CI = 2.115-24.408; P = .002), ulcer size (OR = 1.403; 95% CI = 1.042-1.888; P = .026), and osteomyelitis (OR = 3.390; 95% CI = 1.178-9.756; P = .024) were associated with MDRO infection in patients with DFU.

Wound healing activity of the inflorescence of Typha elephantina (Cattail).
Methanolic extracts of Typha elephantina inflorescence (TE) and its bandage were screened for wound healing by incision and excision wound models in Wistar rats. In the incision wound model, incision wounds were topically treated with TE gel (2.0% [w/w], 3.0% [w/w], and 5.0% [w/w]), Typha elephantina inflorescence bandage, and the reference standard 5.0% w/w povidone iodine for a period of 10 days. When the wounds healed thoroughly, sutures were removed on the 8th postwounding day, and the tensile strength of the skin was measured on the 10th day. ⋯ The increase in tensile strength indicates a promotion of collagen fibers and a firm knitting of the disrupted wound surfaces by collagen. In the excision wound model, higher rate of wound contraction, decreased period of epithelization, elevated hydroxyproline, hexosamine, and ascorbic acid levels, and a significant decrease in malondialdehyde content was observed in treated groups when compared with the wounded control animals. It may be concluded that the inflorescence of Typha elephantina possesses a potent wound healing activity, which may be due to an underlying antioxidant mechanism.
