Cost of lameness in dairy herds: An integrated bioeconomic modeling approach.

Foot disorders are costly health disorders in dairy farms, and their prevalence is related to several factors such as breed, nutrition, and farmer's management strategy. Very few modeling approaches have considered the dynamics of foot disorders and their interaction with farm management strategies within a holistic farm simulation model. The aim of this study was to estimate the cost of foot disorders in dairy herds by simulating strategies for managing lameness. A dynamic and stochastic simulation model (DairyHealthSim) was used to simulate the herd dynamics, reproduction management, and health events. A specific module was built for lameness and related herd-level management strategies. Foot disorder occurrences were simulated with a base risk for each etiology [digital dermatitis (DD), interdigital dermatitis, interdigital phlegmon, sole ulcer (SU), white line disease (WLD)]. Two state machines were implemented in the model: the first was related to the disease-induced lameness score (from 1 to 5), and the second concerned DD-state transitions. A total of 880 simulations were run to represent the combination of the following 5 scenarios: (1) housing (concrete vs. textured), (2) hygiene (2 different scraping frequencies), (3) the existence of preventive trimming, (4) different thresholds of DD prevalence detected and from which a collective footbath is applied to treat DD, and (5) farmer's ability to detect lameness (detection rate). Housing, hygiene, and trimming scenarios were associated with risk factors applied for each foot disorder etiologies. The footbath and lameness detection scenarios both determined the treatment setup and the policy of herd observance. The economic evaluation outcome was the gross margin per year. A linear regression model was run to estimate the cost per lame cow (lameness score ≥3), per case of DD and per week of a cow's medium lameness duration. The bioeconomic model reproduced a lameness prevalence varying from 26 to 98% depending on the management scenario, demonstrating a high capacity of the model to represent the diversity of the field situations. Digital dermatitis represented half of the total lameness cases, followed by interdigital dermatitis (28%), SU (19%), WLD (13%), and interdigital phlegmon (4%). The housing scenarios dramatically influenced the prevalence of SU and WLD, whereas scraping frequency and threshold for footbath application mainly determined the presence of DD. Interestingly, the results showed that preventive trimming allowed a better reduction in lameness prevalence than spending time on early detection. Scraping frequency was highly associated with DD occurrence, especially with a textured floor. The regression showed that costs were homogeneous (i.e., did not change with lameness prevalence; marginal cost equals average cost). A lame cow and a DD-affected cow cost €307.50 ± 8.40 (SD) and €391.80 ± 10.0 per year on average, respectively. The results also showed a cost of €12.10 ± 0.36 per week-cow lameness. The present estimation is the first to account for interactions between etiologies and for the complex DD dynamics with all the M-stage transitions, bringing a high level of accuracy to the results.

Successful management of Mycobacterium haemophilum lower extremity cutaneous infection in a matched-unrelated donor stem cell transplant recipient.

Nontuberculous mycobacterial infections can often occur in individuals with adequate immune function. Such infections typically have cutaneous involvement and are caused by rapidly growing mycobacterium. Other nontuberculous mycobacteria species, like Mycobacterium haemophilum, almost always present as opportunistic infections occurring in severely immunocompromised hosts. Here, we present a complicated and protracted course of diagnosing M. haemophilum lower extremity cutaneous infection in a matched-unrelated donor stem cell transplant recipient.

A VLU complicated by severe group a streptococcal infection resulting in necrotising fasciitis and septic shock: a case report.

This case study outlines the management of a patient with a venous leg ulcer whose swabs cultured Staphylococcus aureus and beta-haemolytic streptococcus group A while in hospital with cellulitis, which was treated with antibiotics as per sensitivities. However, the patient presented at the emergency department five weeks later with a diagnosis of invasive group A streptococcal disease resulting in necrotising fasciitis and streptococcal toxic shock syndrome. This paper describes the holistic care and wound management that the patient received.

It was established that termination of inflammatory process on earlier terms at addition in complex treatment of this pathology of polyvitaminic complex considerably lowering strontium concentration in oral liquid (Patent RU 2210378 from 20.08.2003).

Spinal epidural abscess associated with moxibustion-related infection of the finger.

OBJECTIVE: To describe a spinal epidural abscess that originated from cellulitis after moxibustion. METHODS: Case report. FINDINGS: A 78-year-old woman with diabetes mellitus was diagnosed with tetraplegia due to a cervical spinal epidural abscess extending to the thoracic spinal epidural space. The abscess was caused by osteomyelitis and cellulitis of the right third finger, which had been cauterized repeatedly with moxa. After surgical decompression and drainage of the spinal epidural abscess and comprehensive rehabilitation, motor strength and functional level improved. CONCLUSIONS: This case illustrates the risk of spinal epidural abscess in persons with diabetes mellitus who present with focal cellulitis and osteomyelitis.

[Dynamic magnetotherapy use in comprehensive treatment phlegmons of maxillofacial region and mandible fractures].

145 patients (60 with phlegmons of submandibular and submental regions, 85--with fractures of mandible) were observed and treated with the use of moving pulse magnetic field (MPMF) produced by special apparatus (AMO-ATOS-E, <>, Saratov-city), 60 patients with the same pathology were treated by traditional physical methods and served as control. Use of MPMF led to quicker patient recovery: quicker reduction (if compared with traditional physical methods of treatment) of oedema and soft tissue inflammatory infiltration, quicker relief from inflammatory reaction (according to data of cytokinin profile), improvement of tissue blood supply in the region of fractures in patients with mandible fractures. As the result--we had shortening treatment terms of such patients and complication number reduction.

A case of dissecting cellulitis and a review of the literature.

Dissecting cellulitis (also called perifolliculitis capitis abscedens et suffodiens) manifests with perifollicular pustules, nodules, abscesses and sinuses that evolve into scarring alopecia. It predominantly occurs in African American men between 20-40 years of age, but can occasionally affect other races and women too. Associated musculoskeletal findings are sometimes reported. When it occurs with acne conglobata, hidradenitis suppurativa, and pilonidal cysts, the syndrome is referred to as the follicular occlusion triad or tetrad. Its course is chronic and relapsing, and treatment is often difficult. Medical therapies include isotretinoin, antibiotics, and prednisone. Destructive therapies include X-ray therapy, surgical excision, and skin grafting. Laser epilation of hair follicles is a promising new therapy for dissecting cellulitis.

[Diagnostic significance of evaluating erythrocyte membrane permeability as an intoxication syndrome criterion]. / Diagnosticheskaia tsennost' otsenki pronitsaemosti membran éritrotsitov v kachestve kriteriia intoksikatsionnogo sindroma.

Twenty-five patients with pyoinflammatory maxillofacial diseases treated in an inpatient setting in the Regional Dentistry Clinic of Krasnodar and 8 healthy volunteers were examined. After opening and draining of the purulent focus the patients were divided into 2 groups. Group 1 consisted of 21 patients treated by intravenous 0.04% sodium hypochlorite (SHC) and intravenous infusions of SHC-oxidized autoblood for 2-3 days. Group 2 (6 pts) was treated by intravenous infusions of SHC-oxidized autoblood for 6 days. The criteria of intoxication were erythrocyte resistance tests in hypotonic sodium chloride and at different concentrations of urea in isotonic medium. A new method for evaluating erythrogram deviations from reference values is proposed, which helps adequately assess the severity of intoxication.
