Implanon is a new implantable, progestin-only contraceptive which was approved in the United States in July 2006. Implanon is comprised of a single ethylene vinylacetate copolymer rod that is 4 cm long and 2 mm in diameter. It is inserted subdermally in the groove between the biceps and triceps of the nondominant arm. A literature review was conducted and side effects are discussed. Implanon offers promise as a high-efficacy, long-term contraceptive and can enhance the contraceptive options offered by the women's health care providers. Clinical trial data indicate that the device is both safe and effective. [ABSTRACT FROM AUTHOR]

In recent years there have been numerous media reports of professionals attempting to expand the right of conscience and deny health care services requested by consumers. While the media has focused the most attention on pharmacists' right to refuse access to contraception, this trend is an expansion of the right originally established to protect professionals from being required to perform abortions or to provide direct assistance with abortions. State legislatures have addressed this issue, in some cases by overtly protecting consumers' rights and in other cases by broadening professional right of conscience. In this article, the literature on provider right of conscience is reviewed, and approaches advised by professional organizations are discussed. [ABSTRACT FROM AUTHOR]

This article provides an overview of medication abortion in the United States 6 years after the approval of mifepristone (RU486; Mifeprex; Danco Laboratories, LLC, New York, NY) by the US Food and Drug Administration (FDA). The adoption of mifepristone is considered in the context of epidemiologic data on abortion, abortion access, and the safety of abortion. The risks of medication and aspiration abortion are discussed in the context of abortion-related mortality, recent experience with obstetric and gynecologic infection with Clostridium sordellii, and the limits of scientific knowledge on the incidence of this infection in women. Innovative protocols studied since FDA approval of mifepristone are presented, and implications for clinical practice are discussed. [ABSTRACT FROM AUTHOR]

In September 2000, the U.S. Food and Drug Administration (FDA) approved the use of mifepristone for the provision of medical abortion. Although mifepristone was developed and marketed because of its potential to effect early first-trimester medical abortion, it has additional applications to health care, including the treatment of gynecologic conditions, cancer, and Cushing's disease. The controversial nature of abortion has dominated the publicity about mifepristone. The evidence for the safety and efficacy of mifepristone in medical abortion has been overshadowed, and many clinicians are unaware of the other potential uses of the drug. This article provides a discussion of background information on the pharmacology, development of, and research on mifepristone and an update on current and potential uses in health care today. Information on the FDA-approved regimen and alternative protocols for management of mifepristone in its use in abortion care are presented. [ABSTRACT FROM AUTHOR]

Objective: To describe the overall clinical course of zinc toxicosis in dogs including source, time to source control, incidence of hemolytic anemia, acute liver injury (ALI), acute kidney injury (AKI), and pancreatitis., Design: Retrospective case series from 2005 to 2021., Setting: Six university veterinary teaching hospitals., Animals: Fifty-five client-owned dogs with known zinc toxicosis due to metallic foreign body (MFB) ingestion., Measurements and Main Results: The most common source of zinc was US pennies minted after 1982 (67.3%). Forty-five of 55 (81.8%) dogs survived and 10 of 55 (18.2%) died or were euthanized. Median length of hospitalization for survivors and nonsurvivors was 3 days. The most common clinical sequelae of zinc toxicosis were anemia (87%), ALI (82%), coagulopathy (71%), thrombocytopenia (30.5%), AKI (26.9%), and acute pancreatitis (5.5%). Most dogs (67.3%) required blood products and 83% of dogs achieved a stable HCT or PCV in a median of 24 hours after MFB removal. The median duration of illness prior to presentation was 48 hours for both survivors and nonsurvivors and there was no impact of time to presentation on the incidence of ALI, AKI, or pancreatitis., Conclusions: Zinc toxicosis secondary to MFB ingestion should be considered a differential diagnosis for dogs with gastrointestinal signs, hemolytic anemia, ALI, hemostatic abnormalities, AKI, and pancreatitis. AKI may be a more common sequela of zinc toxicosis than previously suspected. Acute pancreatitis is a rare but potentially serious sequela to zinc toxicosis., (© Veterinary Emergency and Critical Care Society 2023.)

Objective: To report which nonsteroidal anti-inflammatory drugs (NSAIDs) were associated with gastric or duodenal perforation (GDP) in dogs presented to a university teaching hospital and to report the frequency of prescription of NSAIDs by the corresponding referring veterinary community during the same time period., Design: Retrospective cohort study of dogs from January 2007 to March 2020., Setting: Single university teaching hospital., Animals: A total of 30 dogs met inclusion criteria., Measurements and Main Results: Four dogs were administered more than 1 NSAID within 7 days of GDP, 3 dogs received a combination of an NSAID and a corticosteroid, and 1 dog received 2 NSAIDs and a corticosteroid. Four dogs received an overdose of an NSAID. One dog received an overdose of 1 NSAID and received an additional NSAID at the labeled dose within 7 days of GDP. Eighteen dogs received only 1 NSAID at the labeled dose. In these 18 dogs, meloxicam was administered in 44.4% (8/18), firocoxib in 27.8% (5/18), deracoxib in 16.7% (3/18), and piroxicam in 11.1% (2/18). One hundred and sixty surveys on NSAID prescribing practice were returned. Carprofen was the most commonly prescribed NSAID (70.6%), followed by meloxicam (10.6%), deracoxib (8.4%), firocoxib (7.8%), aspirin (1.5%), and other (0.9%)., Conclusions: NSAID administration, even at labeled doses, appears to be a precipitating factor for GDP. Despite carprofen being the most frequently prescribed NSAID over the study period, no case of GDP received it as a single therapeutic agent. Further prospective evaluation is needed to verify these findings., (© Veterinary Emergency and Critical Care Society 2022.)

Objective: To describe placement of an aortic occlusion catheter in aortic zone 1 (Z1) and aortic zone 3 (Z3) in dogs and to compare time to placement in these zones with and without external chest compressions (ECC). Additional evaluations of time to placement in Z1 with time for resuscitative thoracotomy with aortic clamping (RT-AC) were performed., Design: Prospective ex vivo study., Setting: University teaching hospital., Animals: Ten canine cadavers., Interventions: Ten cadaver dogs were obtained from client donation after euthanasia. Cadavers were randomized to have balloon catheter placement into the right or left femoral artery via cutdown, with or without ECC. The xiphoid was used as an external anatomical landmark for Z1, and the spinous process of the 5th lumbar vertebra was used for Z3. Balloon placement was confirmed with radiography. Time to balloon placement in Z1 and Z3 and time to RT-AC were recorded., Measurements and Main Results: Median body weight was 23.5 kg (9-40 kg). Median time to Z1 placement was 6.6 minutes (4.6-12.4 minutes) with ECC and 6.9 minutes (3.3-13.1 minutes) without ECC and was not statistically different (P = 0.5). Median time to RT-AC was 1 minute (0.6-1.4 minutes), which was significantly faster than time to balloon placement in Z1 with or without ECC (P = 0.004 and P = 0.002, respectively)., Conclusions: Endovascular balloon occlusion of the aorta can be achieved by cutdown with and without ECC, but RT-AC is faster. Successful balloon position in Z1 could be achieved with knowledge of external anatomical landmarks, but landmarks for Z3 need further study., (© Veterinary Emergency and Critical Care Society 2022.)

Cutaneous metastasis is a rare manifestation of advanced gastrointestinal (GI) cancers. Gastric adenocarcinoma rarely presents with cutaneous metastasis, as cutaneous manifestations occur in less than 1% of upper GI tract malignancies. Here, we present the case of a patient with advanced gastric cardia adenocarcinoma with metastasis to the right occipital region of the scalp. Following shave biopsy, the immunohistochemistry (IHC) and molecular profile of the scalp lesion were analyzed, both of which confirmed metastasis and guided the treatment approach. The lesion demonstrated programmed death ligand-1 (PD-L1), an immune checkpoint protein, positivity by IHC, which led to the recommendation for treatment with immunotherapy as per the National Comprehensive Cancer Network (NCCN) guidelines. Clinicians should conduct dermatologic examinations in patients with a history of gastric cancer or who are currently undergoing chemotherapy for gastric cancer in order to monitor for disease progression or metastatic lesions. The aim of this report is to increase awareness of scalp metastasis as an indicator of advanced internal visceral carcinoma for earlier diagnosis and improved management of the condition., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2020, Menghani et al.)

Objective: To describe the prevalence of acute kidney injury (AKI), clinical course, decontamination procedures, and outcome in dogs following grape or raisin ingestion., Design: Retrospective case series from 2005 to 2014., Setting: Three university veterinary teaching hospitals., Animals: One hundred thirty-nine client-owned dogs with known grape or raisin ingestion., Measurements and Main Results: Among dogs with biochemical data, the prevalence of AKI was 6.7% (8/120). The prevalence of AKI in the early presentation (3/67) and late (5/53) presentation groups were 4.5% and 9%, respectively. The prevalence of AKI was not significantly different between groups (P = 0.27). Four dogs (3.3%) were azotemic at presentation and 4 dogs (3.3%) had increases in creatinine of ≥26.5 µmol/L (0.3 mg/dL) at recheck (3 from the early and 1 from the late group). Vomiting was the most common clinical sign (18/139). One hundred twenty-two dogs (88%) underwent gastrointestinal decontamination and significantly more dogs in the early group were decontaminated (P < 0.0001). Two dogs received continuous renal replacement therapy. One hundred thirty-eight dogs survived and 1 died., Conclusions: The prevalence of AKI and mortality was low in dogs with confirmed grape or raisin ingestion. Due to the retrospective nature of the study, conclusions about the utility of gastrointestinal decontamination and other therapies cannot be made., (© Veterinary Emergency and Critical Care Society 2019.)

Objective: To describe the clinical use of a novel, minimally invasive technique for fluoroscopic wire-guided esophagojejunal tube (FEJT) placement in dogs and cats., Design: Retrospective study (February 2010-September 2013)., Setting: University veterinary teaching hospital., Animals: Eighteen dogs and 2 cats with intolerance of, or contraindications to, gastric feeding that underwent attempted FEJT placement., Interventions: All patients underwent attempted FEJT placement using a novel fluoroscopic wire-guided technique., Measurements and Main Results: Patient data were collected including information about the FEJT placement and utilization of the tube postplacement. The primary diagnosis in dogs undergoing FEJT placement was pancreatitis in 61% of cases. The ability to achieve postpyloric access with the technique was 95% (19/20). Mean duration of the procedure in dogs where FEJT placement was successful was 63.8 minutes (SD, 28.6; min-max, 30-120 min). Mean fluoroscopy time was 19.4 minutes (SD, 11.5; min-max, 5.2-42.1-min). Esophagostomy site infection was a complication of FEJT placement in 2 dogs. The mean duration the FEJT remained in place in dogs was 3.8 days (SD, 2.2; min-max, 1-7 days), and mean duration of feeding was 3.6 days (SD, 2.2; min-max, 1-7 days). Vomiting was noted in 89% of patients prior to FEJT placement and was significantly reduced to only 24% of patients postplacement (P = 0.0001)., Conclusions: FEJT placement is a viable technique for providing postpyloric nutrition in dogs and cats intolerant of, or with contraindications to, gastric feeding., (© Veterinary Emergency and Critical Care Society 2019.)

Lower urinary tract (LUT) emergencies are common reasons for small animal patients to be presented to their veterinarians. Patient stabilization and management of life threatening problems is a priority in this population. Urethral obstruction is a common LUT emergency. Urethral stent placement has gained popularity over the past decade allowing for a minimally invasive, image-guided method for relief of urethral obstruction in some patient populations. This article focuses on candidate selection, diagnostic workup, stent placement technique, and the expected outcome and complications for patients undergoing urethral stent placement and addresses some additional strategies for interventional management of LUT emergencies., (Copyright © 2018 Elsevier Inc.

This article provides information on recent changes in the US Food and Drug Administration (FDA) labeling and safety regulations for mifepristone (Mifeprex). The revised label now permits midwives, advanced practice nurses, and physician assistants to order and prescribe mifepristone, eliminating the requirement for physician supervision. The updated label also extends eligibility for use from 49 to 70 days' gestation and decreases the number of required visits from 3 to 2. The recommended dose of mifepristone has been reduced, and the dosage, timing, and route of administration for misoprostol have also been changed to reflect current research. These changes have implications for clinical practice and may lead to expanded access for women in the United States., (© 2017 by the American College of Nurse-Midwives.)

Objective: To evaluate a population of dogs for evidence of contrast-induced nephropathy (CIN)., Design: A retrospective case review between 2006 and 2012., Setting: A university teaching hospital., Animals: A total of 1,217 client-owned dogs that were administered intravenous iodinated contrast agents were reviewed for evidence of CIN. Inclusion required a measured serum creatinine within 1 week prior as well as within 1 week following administration of contrast. Eighty-six dogs with 92 contrast administrations qualified for inclusion., Interventions: None., Measurements and Main Results: CIN was defined as an increase in >44.2 μmol/L (0.5 mg/dL) from baseline creatinine concentration within 1 week following administration of an intravenous iodinated contrast agent. A total of 7.6% of contrast administrations (7/92) fulfilled the definition of CIN. The creatinine postcontrast administration as well as the change in creatinine concentration was significantly higher in the CIN group than in the non-CIN group (median postcreatinine 150 μmol/L [1.7 mg/dL] versus 70.7 μmol/L [0.8 mg/dL], median change in creatinine 53 μmol/L [0.6 mg/dL] versus 0 μmol/L). Patient signalment, initial creatinine, number of total contrast administrations, dose of contrast received, duration of anesthesia, IV fluid administration, administration of nephrotoxic agents, and use or vasopressor therapy were not significantly different between groups., Conclusions: The temporal association between contrast administration and renal injury in these cases highlights the potential for CIN in dogs. Due to the retrospective nature of this study, a causal association between contrast administration and renal injury cannot be determined. A prospective study is needed to further evaluate CIN in dogs., (© Veterinary Emergency and Critical Care Society 2016.)

Objective: To develop and describe a technique for percutaneous radiologic gastrojejunostomy tube placement in the dog., Design: Prospective technique development study., Setting: University teaching hospital., Animals: Six healthy adult male Beagles., Interventions: Following anesthetic induction, fluoroscopic and ultrasound guidance were used to identify an appropriate gastropexy site on the left lateral abdomen. Gastropexy was performed using gastrointestinal suture anchors. An over-the-wire catheter technique using fluoroscopic guidance was used to achieve jejunal access. An 18F/8F, 58 cm, dual-lumen gastrojejunal feeding tube was placed via serial over-the-wire dilation of the body wall using an 18F peel-away introducer kit. Tube location was determined radiographically immediately following placement and on days 2, 4, after emesis on day 4, and at time of gastrojejunal feeding tube removal (day 16-18)., Measurements and Main Results: Percutaneous radiologic gastrojejunostomy (PRGJ) tube placement was successful in all dogs. Median time to pyloric passage with the guide wire was 23.5 minutes (range, 9-93 minutes). Median total procedure time was 53 minutes (range, 49-113 minutes). Significant tube migration was not observed at any point during the study. One dog developed linear foreign body obstruction secondary to the tube on day 5 that was relieved by release of the jejunal component. Other complications were minor and included mild-to-moderate peristomal inflammation in all dogs and removal of the feeding tube on day 3 by 1 dog. Feedings were well tolerated in all dogs., Conclusions: PRGJ tube placement in the dog is a safe and minimally invasive technique that allows for jejunal feeding without surgery or endoscopy. The high success rates, acceptable procedural times, and minimal complications are appealing for use in critically ill patients. Although additional evaluations are needed, PRGJ tube placement may be considered for dogs that require postpyloric feeding with or without gastric decompression., (© Veterinary Emergency and Critical Care Society 2016.)

Purpose: The annual pap smear for cervical cancer screening, once a mainstay of the well woman visit (WWV), is no longer recommended for most low-risk women. This change has led many women and their health care providers to wonder if they should abandon this annual preventive health visit altogether. Changing guidelines coinciding with expanded WWV coverage for millions of American women under the Patient Protection and Affordable Care Act have created confusion for health care consumers and care givers alike. Is there evidence to support continued routine preventive health visits for women and, if so, what would ideally constitute the WWV of today?, Methods: A scoping review of the literature was undertaken to appraise the current state of evidence regarding a wide range of possible elements to identify priority areas for the WWV., Findings: A population health perspective taking into consideration the reproductive health needs of women as well as the preventable and modifiable leading causes of death and disability was used to identify eight domains for the WWV of today: 1) reproductive life planning and sexual health, 2) cardiovascular disease and stroke, 3) prevention, screening, and early detection of cancers, 4) unintended injury, 5) anxiety, depression, substance abuse, and suicidal intent, 6) intimate partner violence, assault, and homicide, 7) lower respiratory disease, and 8) arthritis and other musculoskeletal problems., Conclusions: The WWV remains a very important opportunity for prevention, health education, screening, and early detection and should not be abandoned., (Copyright © 2016 Jacobs Institute of Women's Health.

Objective: To compare the effectiveness of single dose activated charcoal, single dose activated charcoal with sorbitol, and multidose activated charcoal in reducing plasma carprofen concentrations following experimental overdose in dogs., Design: Randomized, four period cross-over study., Setting: University research setting., Animals: Eight healthy Beagles., Interventions: A 120 mg/kg of carprofen was administered orally to each dog followed by either (i) a single 2 g/kg activated charcoal administration 1 hour following carprofen ingestion (AC); (ii) 2 g/kg activated charcoal with 3.84 g/kg sorbitol 1 hour following carprofen ingestion (ACS); (iii) 2 g/kg activated charcoal 1 hour after carprofen ingestion and repeated every 6 hours for a total of 4 doses (MD); (iv) no treatment (control)., Measurements and Main Results: Plasma carprofen concentrations were obtained over a 36-hour period following carprofen ingestion for each protocol. Pharmacokinetic modeling was performed and time versus concentration, area under the curve, maximum plasma concentration, time to maximum concentration, and elimination half-life were calculated and compared among the groups using ANOVA followed by Tukey's multiple comparisons test. Activated charcoal, activated charcoal with sorbitol (ACS), and multiple-dose activated charcoal (MD) significantly reduced the area under the curve compared to the control group. AC and MD significantly reduced the maximum concentration when compared to the control group. MD significantly reduced elimination half-life when compared to ACS and the control group. There were no other significant differences among the treatment groups., Conclusions: Activated charcoal and ACS are as effective as MD in reducing serum carprofen concentrations following experimental overdose in dogs. Prospective studies are warranted to evaluate the effectiveness of AC, ACS, and MD in the clinical setting., (© Veterinary Emergency and Critical Care Society 2015.)

Introduction: Certified nurse-midwives (CNMs) across the United States are educated in the same core competencies, yet scope of practice varies with state regulation. The Health Resources and Services Administration (HRSA) funded studies published in 1994 and 2004 on the professional practice environment of CNMs, nurse practitioners, and physician assistants, and developed the Certified Nurse-Midwife Professional Practice Index (CNMPPI), a 100-point scoring system of state regulation focusing on 3 domains: legal status, reimbursement, and prescriptive authority. The purpose of this study was to examine changes to CNM regulation between 2000 and 2015 by updating scores to the CNMPPI., Methods: Individual state CNMPPI scores from 2000 were updated for every year through 2015 by reviewing data published in the American College of Nurse-Midwives (ACNM) quarterly publication Quickening, the annual advanced practice registered nurse legislative updates in the journal Nurse Practitioner, and the ACNM State Legislative and Regulatory Guidance., Results: Mean state scores increased 18%, from 69.7 in 2000 to 79.8 in 2015, and variation between state scores fell. Increases were seen in all 3 domains, with the greatest increase in the domain of prescriptive authority and the smallest in the legal domain. Individual state CNMPPI scores tend to be correlated with scores of adjacent states., Discussion: The CNMPPI can be used to document changes in practice authority of CNMs. The increase in state CNMPPI scores and decrease in variance across states can be interpreted as indicating growth of professional authority and increasing consensus regarding the CNM role. The scoring system needs to be updated to reflect the current health systems environment and to include certified midwives and other midwives meeting the International Confederation of Midwives definition of a midwife. Applications of the CNMPPI to future research are discussed., (© 2015 by the American College of Nurse-Midwives.)

Mild conditions are reported for the hydroxylation of aliphatic C-H bonds through radical translocation, oxidation to carbocation, and nucleophilic trapping with H2O. This remote functionalization employs fac-[Ir(ppy)3] together with Tz(o) sulfonate esters and sulfonamides to facilitate the site-selective replacement of relatively inert C-H bonds with the more synthetically useful C-OH group. The hydroxylation of a range of substrates and the methoxylation of two substrates through 1,6- and 1,7-hydrogen-atom transfer are demonstrated. In addition, a synthesis of the antidepressant fluoxetine using remote hydroxylation as a key step is presented., (© 2015 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.)

Long-acting reversible contraceptive (LARC) methods are underutilized in the adolescent population despite their superior efficacy over non-LARC methods. The purpose of this article is to discuss the barriers that lead to underutilization of these methods and present an evidence-based approach for the use of LARC methods among adolescents in the primary care setting.

Objective: To describe the clinical presentation, treatment, and outcome of a dog with an arterial tumor embolism., Case Summary: An 11-year-old, neutered male Irish Setter presented with acute right forelimb lameness. The dog was unable to bear weight on the right forelimb, which was cool to the touch with no palpable pulses. Diagnosis of thromboembolism was confirmed using angiography, revealing a lack of blood flow to the right axillary artery. Balloon angioplasty, thrombosuction, and infusion of the thromboembolism with tissue plasminogen activator were used to achieve increased, but not complete, blood flow through the vasculature. Echocardiogram revealed vegetative mitral valve lesions consistent with endocarditis, thrombus, neoplasia, or a combination thereof. At the time of discharge, there was improvement in the temperature and motor function of the proximal limb but no conscious proprioception or deep pain sensation in the distal limb. Histopathologic analysis of the sample retrieved with thrombosuction was consistent with a diagnosis of myxosarcoma. A series of 3 rechecks showed continued improvement in neuromuscular function. Treatment for suspected mitral valve myxosarcoma was declined. The patient was lost to follow up until being presented for necropsy 16 months later. Necropsy confirmed myxosarcoma of the mitral valve with tumor emboli to the coronary arteries, lungs, and the right axillary artery., Unique Information Provided: To the authors' knowledge, there is no report of myxosarcoma originating on the mitral valve in dogs, although it has been reported in the human literature. To the authors' knowledge, there are also no reports of tumor embolism of the axillary artery in a dog. This case demonstrates a unique presentation of a dog that had a myxosarcoma tumor embolism. It also describes the use of angiography for diagnosis and localization of the vascular obstruction and a variety of interventional techniques for the treatment of thromboembolism., (© Veterinary Emergency and Critical Care Society 2014.)

Dogs with tracheal collapse may present with life-threatening upper airway obstruction. In most instances, a conservative approach to treatment including oxygen support coupled with sedation and cooling measures will relieve respiratory effort and thus relieve airway obstruction. Dogs that fail this conservative approach require endotracheal intubation to ensure a patent airway. This population of patients would benefit from a more definitive, yet palliative treatment option to acutely relieve upper airway obstruction. Placement of a self-expanding metallic stent that spans the affected portion of the trachea will acutely provide the patient with a sustained patent airway and optimize the likelihood of a positive outcome., (© 2013 Elsevier Inc.

Objective: To determine the prevalence and antimicrobial resistance of enterococci and staphylococci collected from environmental surfaces at a veterinary teaching hospital (VTH)., Design: Longitudinal study., Sample: Samples collected from surfaces in 5 areas (emergency and critical care, soft tissue and internal medicine, and orthopedic wards; surgery preparation and recovery rooms; and surgery office and operating rooms) of a VTH., Procedures: Selected surfaces were swabbed every 3 months during the 3-year study period (2007 to 2009). Isolates of enterococci and staphylococci were identified via biochemical tests, and antimicrobial susceptibility was evaluated with a microbroth dilution technique. A subset of isolates was analyzed to assess clonality by use of pulsed-field gel electrophoresis., Results: 430 samples were collected, and isolates of enterococci (n = 75) and staphylococci (110) were identified. Surfaces significantly associated with isolation of Enterococcus spp and Staphylococcus spp included cages and a weight scale. Fourteen Enterococcus spp isolates and 17 Staphylococcus spp isolates were resistant to ≥ 5 antimicrobials. Samples collected from the scale throughout the study suggested an overall increase in antimicrobial resistance of Enterococcus faecium over time. Clonality was detected for E faecium isolates collected from 2 different surfaces on the same day., Conclusions and Clinical Relevance: Although not surprising, the apparent increase in antimicrobial resistance of E faecium was of concern because of the organism's ability to transmit antimicrobial resistance genes to other pathogens. Results reported here may aid in identification of critical control points to help prevent the spread of pathogens in VTHs.

Objective: To examine the safety and feasibility of using lyophilized platelets (LYO) and fresh platelet concentrate (FRESH) in bleeding thrombocytopenic dogs., Design: Preliminary prospective randomized clinical trial., Setting: Two private referral centers and 3 university teaching hospitals., Animals: Thirty-seven dogs with a complaint of hemorrhage associated with thrombocytopenia (platelet count <70 × 10(9) /L [70,000/μL], a hematocrit >15%, and that had received neither vincristine nor platelet-containing transfusions within 72 h of enrollment were studied., Interventions: Animals were randomized to receive LYO or FRESH, dosed according to weight. Physical examination, complete blood counts, and coagulation testing (prothrombin time and activated partial thromboplastin time) were performed at enrollment. Physical examinations were also performed immediately post transfusion, and at 1 and 24 h after transfusion. Complete blood counts were repeated immediately post transfusion and at 24 h. Collected data included bleeding score (BLS), response to transfusion, adverse reactions, hospitalization time, need for additional transfusions, survival to discharge, and 28-d survival., Measurements and Main Results: Twenty-two dogs received LYO and 15 received FRESH. There was no difference between groups in age, weight, BLS, platelet count, white blood cell count, hematocrit, or presence of melena. There was no difference between groups in transfusion reaction rates, the need for additional transfusions, 24-h BLS, hospitalization time, survival to discharge, or 28-d survival., Conclusions: Transfusion of LYO was feasible and associated with a low transfusion reaction rate in this limited study of thrombocytopenic canine patients presenting with mild-to-severe hemorrhage. LYO were easy to use and provided storage advantages over FRESH. Further study of this product, including examination of efficacy and platelet life span, is warranted., (© Veterinary Emergency and Critical Care Society 2012.)

Using a case study that incorporates patient, nurse practitioner, and student perspectives, we address ethical principles of respect for autonomy, beneficence, and fairness; professionals' right of conscience; and a social justice model for the discussion of prevention and management of unintended pregnancy. Through an ongoing process of self-reflection and values clarification, nurses can prepare for the challenge of applying ethical principles to the reproductive health care of women., (© 2011 AWHONN, the Association of Women's Health, Obsteric and Neonatal Nurses.)

This article provides an overview of the clinical issues in post-abortion care, including types of abortion procedures, expected post-abortion course, possible complications, and the components of the post-abortion visit. By providing follow-up care to their patients, NPs can increase continuity of care and promote successful contraceptive use.

Objective: To determine the outcome of minimally invasive ureteral stent placement for dogs with malignant ureteral obstructions. DESIGN-Retrospective case series., Animals: 12 dogs (15 ureters) with ureteral obstruction secondary to a trigonal urothelial carcinoma., Procedures: In all patients, indwelling, double-pigtail ureteral stents were placed by means of percutaneous antegrade needle and guide wire access under ultrasound and fluoroscopic guidance., Results: Stents were successfully placed in all patients. In 11 of 12 patients, percutaneous antegrade access was accomplished. One patient required access via laparotomy because percutaneous access could not be achieved. The median survival time from the date of diagnosis was 285 days (range, 10 to 1,571 days), with a median survival time of 57 days (range, 7 to 337 days) from the date of stent placement. Three complications occurred in 1 patient. Seven patients required concurrent urethral stent placement for relief of urethral obstruction. All animals were discharged from the hospital (median hospitalization time after stent placement, 18 hours [range, 4 hours to 7 days]) with an indwelling, double-pigtail ureteral stent (3 bilateral and 9 unilateral) in place. All stents evaluated 0.25 to 11 months after placement were considered patent., Conclusions and Clinical Relevance: Findings suggested that ureteral stent placement was safe, effective, and well tolerated in patients with malignant ureteral obstructions. Stents could be reliably placed in a minimally invasive manner and remain patent long-term. Ureteral stent placement should be considered as early as possible in patients with neoplasia, prior to the development of permanent renal damage.

Objective: To describe the clinical use of a novel, minimally invasive fluoroscopic technique for the wire-guided placement of nasojejunal tubes (NJT) in dogs., Design: Retrospective study (September 22, 2006-October 2, 2010)., Setting: University veterinary teaching hospital., Animals: Twenty-six consecutive dogs with intolerance of, or contraindications to gastric feeding that underwent attempted fluoroscopic NJT placement. No dogs were excluded from analysis., Interventions: All dogs underwent attempted fluoroscopic NJT placement using a novel fluoroscopic wire-guided technique., Measurements and Main Results: Patient data were collected in concert with information about the NJT placement procedure as well as the maintenance and utilization of the tube. The primary diagnosis in dogs undergoing NJT placement was pancreatitis in 60%. The ability to achieve transpyloric passage of the tube was 92.3% (24/26) and the ability to achieve jejunal access was 78.2%. In the second half of the study period, the ability to achieve jejunal access was significantly higher than in the first half of the study period suggesting that technical proficiency improves over time. Mean duration of the procedure was 35.3±20 minutes. Significant oral migration was a complication of NJT placement in some dogs. The median duration of feeding was 3.3 days (range 0.3-10.5)., Conclusions: Fluoroscopic wire-guided NJT placement is a viable method for sustained postpyloric feeding in dogs. Success in acquiring jejunal access improves with experience.

This study analyzes the expectations that incoming students and faculty bring to accelerated pre-licensure education programs for second-degree students. Although research supports the congruence of expectations between students and faculty as essential to learning, anecdotal evidence and single case reports suggest there may be important discrepancies in expectations of second-degree students and their faculty. Data are intended to support curriculum review, refinement, and innovation in these programs., (Copyright 2010, SLACK Incorporated.)

Objective: To evaluate the stability of canine and feline hemostatic proteins in freeze-thaw-cycled (FTC) fresh frozen plasma (FFP)., Design: Prospective study., Setting: Veterinary Teaching Hospital., Animals: Nine blood donor dogs and 10 blood donor cats., Interventions: Whole blood was collected and separated into packed RBC and plasma units according to standard methods. Each unit of plasma was divided into 2 equal aliquots and frozen (-41 °C). One aliquot from each donor (FTC) was then thawed and then refrozen (-41 °C) until time of analysis. The second aliquot (nonfreeze-thaw-cycled; NFTC) remained frozen until time of analysis. The hemostatic proteins assessed included coagulation factors, anticoagulant factors (antithrombin and Protein C), and adhesive proteins (fibrinogen and von Willebrand Factor). The coagulant activities of factors II, VII, VIII, IX, X, XI, and XII were measured in modified one-stage activated partial thromboplastin time or prothrombin time assays. Antithrombin and Protein C activities were measured in chromogenic substrate assays. Clottable fibrinogen was measured via the Clauss method, and von Willebrand Factor concentration (vWF:Ag) was measured in an ELISA. A paired t-test was utilized to identify differences in factor activity or concentration between FTC FFP and NFTC FFP., Measurements and Main Results: No clinically or statistically significant differences (all P>0.05) were identified between FTC FFP and NFTC FFP., Conclusions: Refreezing FFP within 1 hour of initial thawing appeared to have no deleterious effects on the hemostatic protein activity or content of that unit. Transfusion of FTC FFP is expected to provide the recipient with comparable replacement of hemostatic proteins as FFP that has remained frozen., (© Veterinary Emergency and Critical Care Society 2010.)

Objective: To describe the computed tomographic and magnetic resonance imaging features of segmental caudal vena cava aplasia and associated vascular anomalies in dogs., Methods: A retrospective study was performed reviewing computed tomographic and magnetic resonance imaging archives of eight institutions for dogs with segmental caudal vena cava aplasia. Inclusion criteria included a computed tomographic or magnetic resonance imaging study and supportive diagnostic and follow-up information. Abdominal vessels were reviewed for size, shape, location and course (including tributaries and branches) and classified as normal, abnormal or shunt vessels., Results: Ten dogs with segmental caudal vena cava aplasia were identified. In all dogs, postrenal caval blood was shunted to either a right or a left azygos vein, with seven different angiographic patterns. Affected dogs were predominantly female (70 per cent) and young (mean 2.6 years). Additional portocaval and porto-azygos shunt vessels were identified in two cases each. Computed tomographic angiography and magnetic resonance angiography depicted details of abdominal vessels including thrombus formation in one dog., Clinical Significance: Segmental caudal vena cava aplasia is a vascular congenital anomaly in the dog that can be associated with thrombosis and portosystemic shunts. Computed tomographic angiography and magnetic resonance angiography are excellent tools to demonstrate the complex vascular anatomy and to guide treatment planning for portosystemic shunts and thrombolytic therapy.

Case Description: A 19-year-old neutered male domestic shorthair cat was evaluated because of signs of urinary tract obstruction., Clinical Findings: Physical examination findings were consistent with urethral obstruction, and a mass could be palpated in the region of the bladder neck. Abdominal ultrasonography and thoracic radiography revealed a mass in the trigone of the urinary bladder and a solitary mass in the left caudal lung lobe. Cytologic examination of the urine sediment, samples obtained by means of traumatic urethral catheterization, and fine-needle aspirates of the bladder mass did not result in a diagnosis., Treatment and Outcome: A balloon-expandable metallic stent was placed in the proximal portion of the urethra to relieve the malignant obstruction. After stent placement, the cat had signs of urinary incontinence and detrusor atony, both of which resolved with medical treatment. The cat was euthanized 1 month after stent placement because of progressive azotemia. Histologic examination of necropsy samples revealed grade III urothelial carcinoma and papillary pulmonary adenocarcinoma., Clinical Relevance: Findings suggested that stent placement may be a viable palliative treatment in cats with malignant urinary obstruction.

Objective: To determine clinical characteristics, treatments, and outcome in dogs and cats evaluated after submersion in freshwater., Design: Retrospective case series., Animals: 25 dogs and 3 cats., Procedures: Medical records were reviewed for signalment; causes, location, and month of submersion; physical examination findings at admission; results of blood gas analysis; treatments administered; duration of hospitalization; and outcome, including evidence of organ failure or compromise., Results: All submersions involved bodies of freshwater. Fourteen animals were submerged in man-made water sources, 13 were submerged in natural water sources, and the body of water was not recorded in 1 case. Twenty (71%) submersions occurred from May through September. Cause was identified in 16 animals and included extraordinary circumstances (n = 6), falling into water (5), breaking through ice (3), and intentional submersion (2). Twelve animals were found submerged in water with unclear surrounding circumstances. Treatment included administration of supplemental oxygen, antimicrobials, furosemide, corticosteroids, and aminophylline and assisted ventilation. Respiratory dysfunction was detected in 21 animals. Neurologic dysfunction was detected in 12 animals, hepatocellular compromise was detected in 6 animals, and cardiovascular dysfunction was detected in 4 animals. Three dogs had hematologic dysfunction, and 2 dogs had acute renal dysfunction. Eighteen (64%) animals survived to hospital discharge, but all of the cats died. In 9 of 10 nonsurvivors, respiratory tract failure was the cause of death or reason for euthanasia., Conclusions and Clinical Relevance: Results suggest that submersion is an uncommon reason for veterinary evaluation but is associated with a good prognosis in dogs in the absence of respiratory tract failure.

Emergency contraception has the potential to greatly reduce the number of unintended pregnancies occurring each year in the United States. Emergency contraception is a safe and effective intervention to which all women should have easy access in the event of an act of unprotected intercourse. Methods of emergency contraception include combined hormone oral contraceptive pills, progestin-only oral contraceptive pills, a dedicated progestin-only emergency contraceptive product, and insertion of a copper intrauterine device. Barriers exist to the increased use of emergency contraception, including the prescription-only status of all of the methods and lack of accurate knowledge on the part of health care providers and consumers. This article provides an overview of the clinical management of emergency contraception.

Acute abdomen is a common clinical complaint identified in small animal patients. Success results from a proactive approach to management,including rapid stabilization of major body systems, early identification of the inciting problem(s), attention to comorbid conditions, and timely definitive therapy.

Objective: To determine survival times in dogs with right atrial hemangiosarcoma treated by means of pericardectomy and tumor resection, with or without adjuvant chemotherapy, and identify complications associated with treatment., Design: Retrospective study., Animals: 23 dogs., Procedure: Dogs were included only if the diagnosis was confirmed histologically., Results: The most common initial complaints included acute collapse (8 [35%] dogs), anorexia or inappetence (8 [35%]), and lethargy (8 [35%]). The most common physical examination abnormalities included muffled heart sounds (12 [52%] dogs), tachycardia (7 [30%]), and weak pulses (7 [30%]). Postoperative complications developed in 12 (52%) dogs; however, most complications were minor. Twenty (87%) dogs were discharged from the hospital. Survival time was significantly longer in the 8 dogs that received adjuvant chemotherapy (mean, 164 days; median, 175 days) than in the 15 dogs that did not receive chemotherapy (mean, 46 days; median, 42 days). Dogs that received chemotherapy were significantly younger and had significantly lower WBC counts than did dogs that did not receive chemotherapy., Conclusions and Clinical Relevance: Results suggested that in dogs with right atrial hemangiosarcoma, surgical resection of the tumor was associated with a low complication rate and complications that did arise typically were minor. In addition, use of adjuvant chemotherapy following resection was associated with significantly longer survival times, compared with resection alone.

Postpartum depression affects an estimated 13% of women who have recently given birth. This article discusses several alternative or complementary therapies that may serve as adjuncts in the treatment of postpartum depression. The intent is to help practitioners better understand the treatments that are available that their clients may be using. Complementary modalities discussed include herbal medicine, dietary supplements, massage, aromatherapy, and acupuncture. Evidence supporting the use of these modalities is reviewed where available, and a list of resources is given in the appendix.

A clear causal relationship has been established between human papilloma virus (HPV) infection and the development of cervical cancer. Genital HPV infection is currently the most common sexually transmitted disease worldwide. The recent 2001 American Society for Colposcopy and Cervical Pathology Consensus Guidelines have included HPV testing for management of women with cervical cytological abnormalities. Clinicians now face the challenge of deciding when to use HPV testing in follow-up of abnormal Pap tests. This article includes updates on HPV, cervical cancer screening, and HPV testing technology. Recommendations for integration of HPV testing into clinical practice are provided.

A 1997 survey revealed that 40% of Americans use some type of complementary therapy or medicine and that many use such therapies in conjunction with treatments prescribed to them by conventional medical practitioners. One alternative modality that is growing in popularity is homeopathy. Although use of this modality is growing, many health care providers know very little about it. This article provides an introduction to homeopathy, including its historical origins and theoretical principles. Also included is a review of two meta-analyses that examined the efficacy of homeopathy in clinical trials. The homeopathic approach to prolonged pregnancy is presented as an example of a potential application to women's health. Information on education and certification in homeopathy is provided, along with resources on homeopathy available to women's health care providers. Implications for nursing practice are discussed.

Vascular endothelial growth factor (VEGF) has potent angiogenic, mitogenic, and vascular permeability enhancing properties specific for endothelial cells. VEGF is present in high concentrations in inflammatory and neoplastic body cavity effusions and has been implicated in the pathogenesis of neoplastic and inflammatory effusion formation. In this study, VEGF was quantitated by solid-phase enzyme-linked immunoadsorbent assay (ELISA) in samples of pericardial, pleural, and peritoneal effusions (N = 38) from dogs (N = 35) with neoplastic and non-neoplastic diseases. VEGF was detected in 37 of 38 effusions (median, 754; range, 18-3,669 pg/mL) and was present in much higher concentrations than in previously established normal concentrations for canine plasma (median, < 1 pg/mL; range, < 1-18 pg/mL) or in those previously noted in the plasma of dogs with hemangiosarcoma (HSA; median, 17 pg/mL; range, < 1-67 pg/mL). In 4 dogs with HSA, the concurrent plasma VEGF concentration was much lower than in the abdominal effusion (P = .029). No significant correlation was demonstrated between VEGF effusion concentration and effusion total protein content or nucleated cell count. Mean VEGF concentrations were significantly higher in pericardial (median, 3,533; range, 709-3,669 pg/mL) and pleural effusions (median, 3,144; range, 0-3,663 pg/mL) compared to peritoneal effusions (median, 288; range, 18-2,607 pg/mL; P < .05). There was no marked difference demonstrated between effusions associated with malignant and nonmalignant diseases. Further studies are necessary to elucidate the role of VEGF in body cavity effusion formation in dogs.
