Pain management during and following disbudding procedures has been studied extensively, though few studies have evaluated wound healing following cautery disbudding in dairy calves. The purpose of this study was to observe wound healing following cautery disbudding with or without treatment using a topical aluminum-based aerosol bandage (ALU) in preweaned dairy calves. Dairy calves were disbudded within the first 3 wk of life using a standard cautery disbudding protocol.

Background: The purpose of this study is to evaluate caregiver assessment of the ease of use of a specially designed toothbrush for providing daily oral infection control (toothbrushing) to persons dependent upon others for activities of daily living.

Method: Eighty-eight caregivers accepted surveys and multi-surface toothbrushes to provide daily oral infection control to the person to whom they assisted. They were asked to evaluate the ease of use of the multi-surface toothbrush, and provide comments about it.

Pediatric craniofacial structures differ from those of adults in many ways. Because of these differences, management of pediatric craniofacial fractures is not the same as those in adults. The most important differences that have clinical relevance are the mechanical properties, craniofacial anatomy, healing capacity, and dental morphology.

We establish the superconductor-insulator phase diagram for quasi-one-dimensional wires by measuring a large set of MoGe nanowires. This diagram is roughly consistent with the Chakravarty-Schmid-Bulgadaev phase boundary, namely, with the critical resistance being equal to RQ=h/4e2. Deviations from this boundary for a small fraction of the samples prompt us to suggest an alternative phase diagram, which matches the data exactly.

The objective of this study was to evaluate associations between bulk tank somatic cell count (BTSCC) and herd management practices using data collected in the National Animal Health Monitoring System Dairy 2002 study. Twenty-six percent and 17.8% of 1,013 operations reported a BTSCC < 200,000 cells/mL and > 400,000 cells/mL, respectively.

Background: This study compared Parietex composite mesh (PCM) with Sepramesh (SM) in terms of strength of tissue incorporation, adhesion formation, and mesh shrinkage, using an animal model.

Study Design: A two-phase, prospective, randomized study using 44 New Zealand white rabbits. Each animal underwent creation of a standardized ventral hernia defect, followed by repair using either SM or PCM.

Objective: To monitor ovine herpesvirus type 2 (OvHV-2) infection status and the association between OvHV-2 infection and development of clinical signs of malignant catarrhal fever (MCF) in cattle.

Design: Longitudinal study.

Animals: 30 mature adult cows and 18 cattle submitted for necropsy.

Surgeons are faced with a wide variety of mesh products, which they can use to perform tension-free abdominal wall hernia repair. The purpose of this study is to compare Sepramesh (SM) and Dualmesh (DM) in terms of strength of tissue incorporation, mesh shrinkage, and adhesiogenesis. We conducted a prospective, randomized trial using 24 New Zealand White rabbits.

Objective: To estimate seroprevalence of Mycobacterium avium subsp paratuberculosis (MAP) infection among adult dairy cows in Colorado and determine herd-level factors associated with the risk that individual cows would be seropositive.

Design: Cross-sectional observational study.

Animals: 10,280 adult (> or = 2 years old) dairy cows in 15 herds in Colorado.

A polymerase chain reaction (PCR) test was compared with culture for the detection and diagnosis of bovine Mycoplasma intramammary infection. The PCR test was applied to 24-hour Mycoplasma enrichment cultures of milk from cows with suspected mastitis and from bulk tank milk. In comparison to culture, the sensitivity and specificity of the PCR method were 96.

2-Octylcyanoacrylate tissue adhesive (Dermabond, Ethicon, Inc, Somerville, NJ) is being used successfully for closure of minor lacerations. To date, however, there have been no studies evaluating its use in the operating room for surgical incisions. We conducted a prospective randomized trial to compare the closure of inguinal herniorrhaphy incisions using 2-octylcyanoacrylate tissue adhesive (Dermabond) with closures using 4-0 Monocryl (Ethicon, Inc) in a running subcuticular closure.

Biosecurity for mammary diseases in dairy cattle.

Vet Clin North Am Food Anim Pract

March 2002

As US dairies grow ever larger and obtain replacement animals from a wide geographical area, biosecurity will loom ever more important as a means of controlling mammary disease. To prevent costly outbreaks of contagious mastitis, introduced animals must be screened for contagious IMI before the resident herd is exposed to them. Screening programs must be instituted to detect the appearance of contagious IMI as soon as possible after introduction has occurred.

The minimal cost algorithm (MCA) commonly used for quantitative coronary arteriography has limitations in definition of complex lesion morphology. A gradient field transform (GFT) algorithm has been designed for the better analysis of complex lesions. We compared MCA with GFT in angiograms of 125 patients in the Myocardial Infarction with Novastan and t-PA (MINT) trial.

2-Octyl cyanoacrylate tissue adhesive is increasingly being used for closure of traumatic lacerations. Data regarding the strength of incisions closed with 2-octyl cyanoacrylate are limited. We compared the strength of disruption of closure with glue with that of more conventional methods of wound closure.

A clinical trial was conducted in a large dairy herd to determine the efficacy of intramammary pirlimycin hydrochloride administration during lactation for bacteriologic clearance of gram-positive environmental clinical and subclinical mastitis infections. Quarters infected with environmental streptococci that received pirlimycin therapy (13/28) were 1.8 times more likely to resolve infection than untreated quarters (5/14).

Idiopathic spontaneous intraperitoneal hemorrhage is a rare and often fatal condition that has been historically referred to as abdominal apoplexy. The presentation varies widely, and preoperative diagnosis is seldom obtained. Immediate surgical exploration remains the treatment of choice.

Fibrin as a tissue sealant has been used since the turn of the century for hemostasis. The development of cryoprecipitate and the resultant availability of higher concentrations of fibrinogen have led to a resurgence of interest in this material. Fibrin glue has since been shown to be effective for numerous applications throughout the field of surgery.

Using a polymerase chain reaction (PCR) test for sequences of ovine herpesvirus 2 (OHV2), this virus was shown to be significantly associated with sheep-associated malignant catarrhal fever (SA-MCF) in terminal cases of disease in 34 cattle and 53 bison. Ovine herpesvirus 2 was not detected in cattle (38) and bison (10) that succumbed to other diseases. Other persistent herpesviruses, retroviruses, and pestivirus, some of which have been previously isolated from cases of SA-MCF, were not associated with the disease.
