Versatility of the abductor hallucis muscle as a conjoined or distally-based flap

Soft tissue coverage of the medial ankle and foot remains a difficult, challenging, and often frustrating problem to patients as well as surgeons. To our knowledge, the abductor hallucis muscle flap is not frequently used and only a few well documented cases were found in literature. The purpose of this paper is to report and to present the long-term results of a series of four patients who underwent reconstruction of foot and ankle defects with the abductor hallucis muscle flap.In two cases, the abductor hallucis muscle flap was transposed in combination with a medialis pedis flap to cover a medial ankle defect, whereas in another case it was combined with a medial plantar flap. In this latter case, the muscle flap served to fill up a calcaneal dead space after osteomyelitis debridement, whereas the cutaneous flap was used to replace debrided skin at the heel. The abductor hallucis flap was used as a distally-based turnover flap to cover a large forefoot defect in a fourth case. Follow-up period ranged between 18 and 64 months (mean 43.3). In the early postoperative period, two flaps healed completely In two patients marginal flap necrosis occurred which was subsequently skin grafted. No donor-site complication occurred in any of the patients. In all cases, protective sensation of the skin was satisfactory as early as 6 months. In two cases mild hyperkeratosis at the skin graft border to the sole skin (non-weight bearing area of medial plantar and medialis pedis flap donor site) was present, but probably related to poor foot care. All patients were fully mobile as early as 3 months after treatment. In the long-term follow-up (43.3 months), all flaps provided with durable coverage. Functional gait deficit due to consumtion of the abductor hallucis muscle was not apparent.Our long-term results demonstrated that the abductor hallucis muscle flap is a versatile, and reliable flap suitable for the reconstruction of foot and ankle defects. Utilizing the abductor hallucis muscle as a pedicled flap (distally or proximally-based) with or without conjoined regional fasciocutaneous flaps offers a successful and durable alternative to microsurgical tree flaps for small to moderate defects over the calcaneus region, medial ankle, medial foot, and forefoot with exposed bone, tendon, or joint.

Synovitis, acne, pustulosis, hyperostosis, osteitis (SAPHO) syndrome in childhood: a report of ten cases and review of the literature

Chronic recurrent multifocal osteomyelitis is a rare chronic inflammatory musculoskeletal process observed in children and young adults. Recently, the acronym SAPHO syndrome (for synovitis, acne, pustulosis, hyperostosis, osteitis) was coined to emphasise the association between osteo-articular inflammations and different skin abnormalities which are aseptic and filled with neutrophils. In adults, chronic recurrent multifocal osteomyelitis is now a classical manifestation of SAPHO syndrome. Chronic skin disorders were seen in eight of ten children on follow-up at the University Children's Hospitals in Bern and Zurich and in 61 of 260 paediatric cases reported in the literature. The different skin lesions were palmoplantar pustulosis (n = 40), non-palmoplantar pustulosis (n = 6), psoriasis vulgaris (n = 16) or severe acne (n = 4). More rarely Sweet syndrome (n = 2) or pyoderma gangrenosum (n = 1) were reported. Conclusion: The synovitis, acne, pustulosis, hyperostosis, osteitis syndrome is pertinent even in paediatrics since skin involvement is frequent.

Diseases in neonatal foals. Part 1: the 30 day incidence of disease and the effect of prophylactic antimicrobial drug treatment during the first three days post partum

REASONS FOR PERFORMING STUDY: Neonatal diseases have been grouped and analysed but up-to-date statistically significant information about the incidence and prevalence of diseases in foals is limited. Since the 1950s it has been a common management practice to administer a 3 day course of antimicrobial drugs to neonatal foals. This was shown to significantly reduce the incidence of infections (Platt 1977). Since then management practices have improved and it is widely believed that prophylactic antimicrobial drugs are no longer necessary in foal rearing. OBJECTIVES: To determine the 30 day incidences or prevalences (depending on case definition) of various diseases and conditions in the neonatal foal and ascertain the influence of a prophylactic 3 day treatment on the frequency of infections. METHODS: The population consisted of Thoroughbred foals born on stud farms in the Newmarket (UK) area in 2005 (n = 1031). Depending on the stud farm's practice in the use of prophylactic antimicrobial drugs, 2 groups of newborn foals (treated and untreated) were identified and followed for 30 days. RESULTS: The 30 day incidences of infectious diseases under study were between 0.2% (osteomyelitis) and 5.85% (systemic disease with diarrhoea). The overall incidence for 'total infectious diseases' was 8.27%. The most commonly observed noninfectious condition was limb deformities (12.11% of all foals). There was no significant difference in the incidence of infectious diseases between the 2 groups. CONCLUSION: Infectious diseases are still an important problem in neonatal foals requiring further investigation as to which factors other than antimicrobial prophylaxis are relevant for disease prevention. POTENTIAL RELEVANCE: The results provide an up-to-date overview about the frequencies of various neonatal foal diseases. They do not support the traditional prophylactic use of antimicrobials to prevent infectious diseases in healthy newborn foals. However, it should be noted that this study was not a randomised controlled trial and therefore does not provide the strongest possible evidence for this conclusion.

Daptomycin versus vancomycin for osteoarticular infections due to methicillin-resistant Staphylococcus aureus (MRSA): a nested case-control study

Vancomycin is the standard antibiotic for the treatment of methicillin-resistant Staphylococcus aureus (MRSA) infections. While daptomycin is approved for MRSA bacteremia, its effectiveness in osteoarticular infections (OAIs) has not been established. A 1:2 nested case-control study of adult patients with MRSA OAIs admitted to an academic center from 2005 to 2010 was carried out. Clinical outcomes and drug toxicity in patients treated with daptomycin versus vancomycin were compared. Twenty patients with MRSA OAIs treated with daptomycin were matched to 40 patients treated with vancomycin. The median age of the patients was 52 years (range, 25-90), and 40 (67 %) were male. Most patients had osteomyelitis (82 %), predominantly from a contiguous source (87 %). Forty percent were diabetics. Diabetic patients were more likely to receive vancomycin than daptomycin [20 (50 %) vs. 4 (20 %); p = 0.03]. Vancomycin was more often combined with antibiotics other than daptomycin [22 (55 %) vs. 5 (25 %); p = 0.03]. The median total antibiotic treatment duration was 48 (daptomycin) vs. 46 days (vancomycin) (p = 0.5). Ninety percent of daptomycin-treated patients had previously received vancomycin for a median of 14.5 days (range, 2-36). Clinical success rates were similar between daptomycin and vancomycin at 3 months [15 (75 %) vs. 27 (68 %); p = 0.8] and 6 months [14 (70 %) vs. 23 (58 %); p = 0.5], even after propensity score-based adjustment for antibiotic assignment. The frequency of adverse events was similar between treatment groups [1 (5 %) vs. 7 (18 %); p = 0.2]. Daptomycin and vancomycin achieved similar rates of clinical success and drug tolerability. Daptomycin is a reasonable alternative for treating MRSA OAIs, particularly in patients where therapy with vancomycin has not been well tolerated.

Reactivated Moraxella osteitis presenting as granulomatous disease.

Granulomatous infections are commonly associated with mycobacteria, brucellosis, actinomycosis, nocardiosis, spirochetes, and fungi. Rarely, granuloma formation is a host response to other bacterial infection. Osteomyelitis and osteitis that reactivate many years after the primary episode is a known phenomenon. A reactivation that presents as a granulomatous disease is rare. We present a case of reactivated osteitis due to Moraxella osloensis with consecutive granuloma formation.
