Pseudohypoaldosteronism and acquired renal aldosterone resistance with hyperkalemic type IV renal tubular acidosis in 2 cats.

This report describes the diagnosis and treatment of aldosterone resistance (AR) and acquired hyperkalemic type IV renal tubular acidosis (RTA) in 2 cats comparable to acquired pseudohypoaldosteronism in people. One cat developed AR from chronic kidney disease after an acute kidney injury and was treated with furosemide per os, which resolved the hyperkalemic RTA. The second cat developed transient AR secondary to a bacterial urinary tract infection associated with urethral catheterization, and treatment with antibiotics resolved the hyperkalemic RTA.

Patients' experience of accessing support for tics from primary care in the UK: an online mixed-methods survey.

BACKGROUND: Tics are common in children and young people and may persist into adulthood. Tics can cause challenges with social, occupational, physical, and academic functioning. The current study explores the perceptions of adults with tics and parents/carers of young people with tics regarding their experience of accessing support from professionals in primary care in the UK. METHODS: Two online cross-sectional surveys were completed by 33 adults with tics and 94 parents/carers of children with tics. Participants were recruited across three online tic support groups. Tic specialist psychologists, academic researchers, and people with lived experience of tics provided feedback on the surveys before they were made available online. Mixed-method analyses were conducted on the surveys. Qualitative data from the free-text responses were analysed using thematic analysis and triangulated with quantitative findings where appropriate. RESULTS: While some participants felt supported by general practitioners (GPs), many felt dismissed. The impact of tics was not always explored, nor information on tics provided, during the consultation. Although 78.7% of participants were referred to secondary care for their tics, some struggled to get the referral. Within secondary care, most adult respondents were assessed by neurologists whilst young people were typically assessed by paediatricians or psychiatrists. Most of these secondary care clinicians did not specialise in tic disorders, with only 27.9% of participants being assessed by tic specialists. Mode waitlist time was 3-6 months for young people and longer for adult respondents. Some participants were referred to multiple secondary care services, spanning neurology, paediatrics, and psychiatry, with each stating that they do not provide support for tics. 21% of participants mentioned being discharged from secondary care with no ongoing support. Almost one-third of respondents accessed support within private healthcare. CONCLUSIONS: Generally, more negative than positive experiences were reported. Possible contributing factors included a lack of clear tic referral pathways, long waitlists, a lack of information about tics provided in primary care appointments and a lack of support offered following diagnosis by secondary care services, together with poor access to tic specialist clinicians. This study highlights areas where improvements to UK services for tics can be made.

Diagnosis and treatment of epidural empyema in a pygmy goat.

A mixed-breed pygmy goat was presented for nonambulatory tetraparesis. Neurological examination was consistent with a C6 to T2 myelopathy. Initially, the goat was treated medically. Forty-three days later, magnetic resonance imaging (MRI) revealed an extradural mass compressing the cervical spinal cord. Magnetic resonance attributes of the mass were consistent with a slow-growing, fluid-poor lesion. The spinal cord was surgically decompressed. Epidural empyema secondary to Fusobacterium necrophorum was identified. Postoperative care consisted of anti-inflammatory medication, antimicrobials, and physical therapy. Ability to walk occurred by day 14 after surgery. Despite prolonged recumbency before surgery, the goat was clinically normal, and antimicrobials were discontinued on day 60 after surgery. Key clinical message: Epidural empyema can cause a compressive myelopathy which may result in varying degrees of paresis/paralysis. Clinical resolution and return of normal function occurred following the use of MRI to plan surgical decompression combined with extended use of antimicrobials.

Diagnostic et traitement d'un empyème épidural chez une chèvre pygmée. Une chèvre naine fut présentée pour tétraparésie non-ambulatoire, neuro-localisée au segment C6-T2. Un traitement conservateur fut initialement instauré. Quarante-trois jours plus tard, une IRM révéla une compression sévère de la moelle épinière cervicale par une masse extradurale faiblement liquide et à croissance lente. La moelle épinière fut chirurgicalement décompressée. Un empyème épidural secondaire à Fusobacterium necrophorum fut identifié. Des soins postopératoires à base d'anti-inflammatoires, d'antibiotiques ainsi qu'une rééducation physique furent instaurés. L'animal recouvra la capacité de marcher 14 jours plus tard. Malgré un décubitus prolongé, 60 jours après la chirurgie la chèvre était normale et les antimicrobiens furent interrompus.Message clinique clé :L'empyème épidural peut provoquer une myélopathie compressive pouvant entraîner divers degrés de parésie/ paralysie. La résolution clinique et le retour de la fonction normale sont survenus après l'utilisation de l'IRM pour planifier la décompression chirurgicale combinée à une utilisation prolongée d'antimicrobiens.(Traduit par Karin Gendron et Maëva Barozzi).

Atypical chronic myeloid leukemia in a German Shepherd Dog.

A 4-y-old neutered male German Shepherd Dog was presented with a 3-d duration of lethargy, restlessness, and vomiting. Physical examination revealed generalized lymphadenopathy, pale mucous membranes, systolic heart murmur, dehydration, and fever. Hematologic abnormalities included moderate-to-marked leukocytosis, characterized by neutrophilia with a left shift to progranulocytes and 2% presumptive myeloid blasts, marked anemia that was nonregenerative, and marked thrombocytopenia. Dysplasia was evident in neutrophils and platelets. Bone marrow examination revealed marked myeloid and megakaryocytic hyperplasia with 7% blasts, erythroid hypoplasia, and trilineage dysplasia. Flow cytometric analysis confirmed that bone marrow cells were mostly of neutrophil lineage, with reduced expression of common leukocyte antigens (CD45, CD18) and neutrophil-specific antigen. Bone marrow cells were cytogenetically analyzed for the breakpoint cluster region-Abelson oncogene using multicolor fluorescent in situ hybridization. The genetic aberration was present in 7% of cells, which was a negative result (>10% of cells is considered positive). Euthanasia was elected. Histologic examination showed extensive infiltration of multiple organs by neoplastic myeloid cells, with effacement of lymph node and splenic architecture. The final diagnosis was atypical chronic myeloid leukemia (aCML), an uncommon myeloproliferative disorder with features of myelodysplastic syndromes (dysplasia) and chronic leukemia (neutrophilic leukocytosis with <20% marrow blasts, extramedullary infiltrates). The trilineage dysplasia, lack of monocytosis, and supporting cytogenetics distinguish aCML from CML, chronic neutrophilic leukemia, and chronic myelomonocytic leukemia.

Prevalence and classification of chronic kidney disease in cats randomly selected from four age groups and in cats recruited for degenerative joint disease studies.

Chronic kidney disease (CKD) and degenerative joint disease are both considered common in older cats. Information on the co-prevalence of these two diseases is lacking. This retrospective study was designed to determine the prevalence of CKD in two cohorts of cats: cats randomly selected from four evenly distributed age groups (RS group) and cats recruited for degenerative joint disease studies (DJD group), and to evaluate the concurrence of CKD and DJD in these cohorts. The RS group was randomly selected from four age groups from 6 months to 20 years, and the DJD group comprised cats recruited to four previous DJD studies, with the DJD group excluding cats with a blood urea nitrogen and/or serum creatinine concentration >20% (the upper end of normal) for two studies and cats with CKD stages 3 and 4 for the other two studies. The prevalence of CKD in the RS and DJD groups was higher than expected at 50% and 68.8%, respectively. CKD was common in cats between 1 and 15 years of age, with a similar prevalence of CKD stages 1 and 2 across age groups in both the RS and DJD cats, respectively. We found significant concurrence between CKD and DJD in cats of all ages, indicating the need for increased screening for CKD when selecting DJD treatments. Additionally, this study offers the idea of a relationship and causal commonality between CKD and DJD owing to the striking concurrence across age groups and life stages.

Clinical nurse specialists shaping policies and procedures via an evidence-based clinical practice council.

In the practice of nursing, organizations with progressive evidence-based practice programs implement structures and processes whereby nurses are engaged in the review of existing research and in the development of clinical practice documents to better align nursing practices with the best available scientific knowledge. At our academic hospital system, clinical nurse specialists (CNSs) took the lead to help transform a traditional nursing policy and procedure committee into a hospital-wide, staff-represented Clinical Practice Council (CPC) that ensures evidence-based nursing practices are reflected in the organization's nursing practice documents for the provision of patient care. Clinical nurse specialists function as mentors and cochairs who are dedicated to ensuring that nursing practice is supported by the latest evidence and committed to guiding staff nurses to continually move their practice forward. The success of the CPC is due to the leadership and commitment of the CNSs. This article describes the structure, process, and outcomes of an effective CPC where CNSs successfully engage frontline clinicians in promoting nursing care that is evidence based. Clinical nurse specialist leadership is increasingly made visible as CNSs effectively involve staff nurses in practice reforms to improve patient outcomes.

Cycloheximide impairs reconsolidation of a contextually reactivated memory in a conditioned taste aversion paradigm.

Rats were used to examine the impact of systemic protein synthesis inhibition (PSI) on the reconsolidation of a contextually reactivated memory of conditioned taste aversion (CTA). Rats were administered intraperitoneal injections of saline or lithium chloride (LiCl; .15 M) following exposure to a novel sucrose solution in a unique context. Seven days later, rats were injected subcutaneously with saline or cycloheximide (CXM; 1 mg/kg) and returned to their home cage or placed into the CTA training context in the absence of the target conditioned stimulus to reactivate the training memory. At testing, LiCl-trained rats that had been given CXM at reactivation had significantly greater difference scores (sucrose-water) in comparison with LiCl/CXM rats that had not been given a reactivation treatment and LiCl/saline memory-reactivated rats. These results suggest that context re-exposure effectively reactivates memory of CTA training that may be weakened through PSI. Extinction tests revealed rapid attenuation of taste aversions in all of the LiCl-injected groups. The involvement of taste-potentiated aversions and the role of the context in taste aversion conditioning are discussed.

Use of the Pyrithiamine-Induced Thiamine Deficient Animal Model of Korsakoff's Syndrome for Exploratory Research Activities in Undergraduate Physiological Psychology.

Undergraduate neuroscience laboratory activities frequently focus on exercises that build student's wet/dry laboratory skills, foster critical thinking, and provide opportunities for hands-on experiences. Such activities are, without a doubt, extremely important, but sometimes fall short of modeling actual research and often lack the 'unknown' hypothetical nature accompanying empirical studies. In this article we report a series of research activities using an animal model of Korsakoff's syndrome in a Physiological Psychology course. The activities involve testing hypotheses regarding performance of animals with experimentally-induced Korsakoff's syndrome and the effectiveness of glucose as a memory-enhancer in this model. Students were given a set of 24 articles for use in answering a series of laboratory report questions regarding the activities. At the conclusion of the course, students were asked to complete a questionnaire designed to assess the effectiveness of the laboratory activities. Results of the laboratory exercises indicated that locomotor activity, environmental habituation, and anxiety were unaffected in the Korsakoff condition, and glucose had no effect. Results of performance in the T-maze indicated that Korsakoff animals had significantly fewer spontaneous alternations than controls, but Korsakoff animals given glucose did not reveal this difference. Results of the student assessments indicated that the activities were considered educational, challenging, and more interesting than standard laboratory activities designed to reproduce reliable phenomena.

Effect of community coalition structure and preparation on the subsequent implementation of cancer control activities.

PURPOSE: The purpose of this paper is to identify factors within a three-phase community coalition development model that influence short-term success in cancer control coalitions based on the cumulative number of educational and screening activities conducted by the coalitions. DESIGN: This study was a nonrandomized community intervention trial involving four autonomous, independently funded multistate projects aimed at using coalitions to increase cancer screening and early detection. SETTING: The study was conducted in medically underserved, rural counties of Appalachia. SUBJECTS: Sixty-three coalitions involved 1725 members representing 71 counties within 10 states. Intervention. A network of local and regional community cancer control coalitions throughout rural Appalachia delivered culturally sensitive cancer control messages to women, with the long-term goal of increasing the early detection of breast cancer ANALYSIS: County-level coalitions were the unit of analysis for this study. Multiple linear regression was used to determine if three classes of variables corresponding to the developmental history of coalitions--formation, preparation for implementation, and implementation--were associated with the number of educational and screening activities conducted by the coalitions. RESULTS: The presence of a paid coordinator and formal organizational structure were both strongly associated with the number of activities conducted, accounting for 71% of the variability in coalition activities. Other variables positively associated with number of activities were the preparation of written community assessments and the modification of implementation plans. The same factors (structure, written plans) were associated with activities in coalitions without paid organizers (r2 = .57), as was the number of meetings. However, such coalitions produced an average of only 2.2 activities vs. 21.7 activities in coalitions with paid coordinators. CONCLUSION: The ALIC study would seem to indicate that community-based coalitions with paid coordinators and formal structures are capable of generating significantly higher levels of activity than those without either a paid coordinator or formal structure.
