Colonic Hamartomatous Ganglioneuromatosis in a 4 Mo Old Puppy.

A 4 mo old male goldendoodle puppy was evaluated for chronic hematochezia with a history of recurrent rectal prolapse and tenesmus. A colo-colonic intussusception was diagnosed via abdominal imaging. Surgery was elected to reduce the intussusception, wherein a colonic mass was discovered. Colonic resection and anastomosis was performed, and the tissue were submitted for histopathological examination. The puppy was diagnosed with colonic hamartomatous ganglioneuromatosis based on the presence of markedly hyperplastic submucosal and myenteric plexi with infiltration and expansion of the mucosa and submucosa by Schwann cells and neuronal cell bodies. Ganglioneuromatosis is a rarely reported entity in the veterinary literature, and limited clinical follow up data is available for described cases. In humans, ganglioneuromatosis is associated with a PTEN genetic mutation, which confers increased susceptibility to the development of neoplasia of endocrine organs. Approximately 1 yr after the operation, this puppy appeared clinically normal with no abnormalities on repeated imaging. This case report describes the clinical presentation, surgical treatment, and histologic features of colonic hamartomatous ganglioneuromatosis with 1 yr postoperative clinical follow up data in a dog. Although uncommon, ganglioneuromatosis should be considered as a differential diagnosis list as a cause of gastrointestinal masses in puppies and young dogs.

High-grade mucoepidermoid carcinoma of the salivary gland in a bull.

Salivary gland neoplasia is uncommon in veterinary species and has rarely been reported in cattle. Adenocarcinoma, squamous cell carcinoma, and pleomorphic carcinoma have been described in the parotid gland of dairy cows. Here we describe a case of high-grade mucoepidermoid carcinoma in a bull. The bull had a chronic history of caudal mandibular soft tissue swelling. Postmortem examination revealed a 30 × 30-cm mass with a caseonecrotic center, hemorrhage and necrosis of the ipsilateral cervical musculature, osteolysis of the right paracondylar process of the skull and right horn base, pulmonary nodules, and enlarged tracheobronchial lymph nodes. Histology of the mass, lungs, and lymph nodes revealed an invasive neoplasm composed of epithelial cells arranged in nests and ductular structures supported by a spindle cell stroma, with frequent central necrosis. Immunohistochemistry revealed that epithelial cells were diffusely positive for pancytokeratin and p63 with multifocal vimentin positivity; stromal cells were diffusely positive for vimentin and α-SMA. A salivary gland mucoepidermoid carcinoma was diagnosed based on these findings. Although rare, salivary gland neoplasia should be considered a differential diagnosis for mandibular masses in cattle.

Preparing for the Next Generation NCLEX Using a Virtual Simulation.

BACKGROUND: Virtual clinical simulation is a digital innovation that augments clinical reasoning and clinical judgment, narrowing the theory-practice gap, preparing new graduates for the Next Generation NCLEX (National Council Licensure Examination), and mitigating the demand for clinical placement and clinical faculty. METHOD: The purpose of this article is to describe an educational innovation employing a virtual clinical simulation using the tenets of Tanner's Clinical Judgment Model and a National League for Nursing Advancing Care Excellence for Seniors unfolding case. RESULTS: A virtual clinical simulation successfully served to replace direct care clinical for 86 undergraduate nursing students enrolled in a foundation nursing course, augmenting the students' ability to transfer and apply theoretical knowledge to clinical practice. CONCLUSION: This virtual clinical simulation served as a viable platform for teaching clinical reasoning and clinical judgment, mitigating the education-practice gap for new graduate registered nurses.

Neurolymphomatosis caused by T-cell lymphosarcoma in a cat: imaging description and treatment review.

CASE SUMMARY: A 16-year-old domestic shorthair cat was evaluated for acute-onset right pelvic limb monoparesis localized to the sciatic nerve. MRI revealed a homogeneously contrast-enhancing, well-demarcated mass effacing the right sciatic nerve from its intravertebral origin to the end of the viewable field (mid-femur). Abdominal ultrasound revealed thickened small intestinal loops and enlarged mesenteric lymph nodes. Cytology of the small intestine was suggestive of lymphosarcoma. T-cell lymphosarcoma of the sciatic nerve and small intestines was confirmed with incisional biopsy. Treatment consisted of systemic chemotherapy with vincristine followed by the Wisconsin-Madison feline lymphosarcoma protocol, but despite treatment the patient neurologically worsened and was euthanized after 54 days. RELEVANCE AND NOVEL INFORMATION: We present herein one of the first descriptions of neurolymphomatosis in the domestic cat that included post-intravenous contrast MRI. Treatment options based on recommendations for people with neurolymphomatosis include systemic chemotherapy, intrathecal chemotherapy and/or localized radiation chemotherapy. The authors recommend that all cats be screened for concurrent non-neuronal areas of lymphosarcoma before undergoing treatment for neurolymphomatosis, regardless of clinical signs.

Transdermal gel in the treatment of postoperative pain.

Postoperative pain can be difficult to control in the outpatient setting. Pain management is often a progressive process, involving adustment of the dosage, strength, and/or ingredients of pain medication to relieve a patient's pain. Counseling should be incorporated into the treatment program. While opioids can be effective in the relief of postoperative pain, their use is associated with debilitating side effects. Oral nonsteroidal anti-inflammatory drugs are a popular class of nonopioid analgesics, but they are also associated frequently with adverse effects. Patients, physicians, and pharmacists should be educated in pharmacological alternatives to these analgesics. One option is the transdermal application of medications, which allows the patient to experience relief without unwanted systemic side effects that routinely occur with oral medications.
