For many people, companion animals are family members and partners in life. The diagnosis of a life-threatening illness in a beloved pet can present challenges for the patient and cause stress and grief for its owner. A successful therapeutic outcome often requires the use of commercially manufactured medications that are not produced in the doses or dosage forms tolerated by veterinary patients or are unavailable to, unaffordable for, and/or inaccessible by owners. In those cases, the use of customized compounded preparations is often the best option. In this report, we describe the successful use of 2 compounds (cyclophosphamide and piroxicam) to treat an aggressive peripheral nerve sheath tumor in an older male dog. Formulations for those medications are provided.

Malignant peripheral nerve sheath tumors (MPNSTs) are soft tissue sarcomas that develop from peripheral nerve sheath cells (T. Hirose, B.W. Scheithauer). These tumors are characterized by aggressive g...
Malignant peripheral nerve sheath tumors are rare sarcomas of children and adolescents, and they are aggressive tumors with a high rate of local recurrence. Here we report a case of a primary cardiac ...
Malignant peripheral nerve sheath tumor (MPNST) is a rare type of soft tissue sarcoma (STS) that carries significant mortality. Given the rarity of MPNST, current knowledge on the disease is limited. ...
Malignant peripheral nerve sheath tumor occurring in the context of neurofibromatosis type I (NF1) is relatively rare. Herein, we report a case of NF1 with malignant peripheral nerve sheath tumor in t...
Malignant peripheral nerve sheath tumors contain loss of histone H3K27 trimethylation (H3K27me3) due to driver mutations affecting the polycomb repressive complex 2 (PRC2). Consequently, loss of H3K27...
This is phase II, single arm, open-label, interventional trial of pembrolizumab (MK-3475) in subjects with metastatic or locally advanced/unresectable or metastatic malignant peripheral ne...
It is reported that optic nerve sheath diameter increases when higher volume of medication is injected during epidural anesthesia. This study is designed to compare the optic nerve sheath...
To determine the clinical benefit rate of selumetinib in combination with vistusertib in patients with unresectable or metastatic neurofibromatosis type 1 (NF1) associated or sporadic MPNS...
Patient undergoing laparoscopic radical prostatectomy in steep trendelenburg position are at risk to develop complication from brain edema. Ultrasound assessment of optical nerve sheath d...
This phase I trial studies the side effects and the best dose of a vaccine therapy in treating patients with malignant peripheral nerve sheath tumor that cannot be removed by surgery (unre...
Neoplasms which arise from nerve sheaths formed by SCHWANN CELLS in the PERIPHERAL NERVOUS SYSTEM or by OLIGODENDROCYTES in the CENTRAL NERVOUS SYSTEM. Malignant peripheral nerve sheath tumors, NEUROFIBROMA, and NEURILEMMOMA are relatively common tumors in this category.
Neoplasms which arise from peripheral nerve tissue. This includes NEUROFIBROMAS; SCHWANNOMAS; GRANULAR CELL TUMORS; and malignant peripheral NERVE SHEATH NEOPLASMS. (From DeVita Jr et al., Cancer: Principles and Practice of Oncology, 5th ed, pp1750-1)
The lipid-rich sheath surrounding AXONS in both the central and peripheral nervous systems. The myelin sheath is an electrical insulator and allows faster and more energetically efficient conduction of impulses. The sheath is formed by the cell membranes of glial cells (SCHWANN CELLS in the peripheral and OLIGODENDROGLIA in the central nervous system). Deterioration of the sheath in DEMYELINATING DISEASES is a serious clinical problem.
A class of nerve fibers as defined by their structure, specifically the nerve sheath arrangement. The AXONS of the unmyelinated nerve fibers are small. The axons to SCHWANN CELLS ratio is greater in the unmyelinated nerve fibers than that in the myelinated fiber (NERVE FIBERS, MYELINATED) which is 1:1. Usually several axons are surrounded by a single Schwann cell in the unmyelinated nerve fibers. Therefore, each unmyelinated fiber is not completely covered by the MYELIN SHEATH formed by the Schwann cell. Unmyelinated nerve fibers conduct impulses at low velocities. They represent the majority of peripheral sensory and autonomic fibers. They are also found in the spinal cord and brain.
Mechanical compression of nerves or nerve roots from internal or external causes. These may result in a conduction block to nerve impulses (due to MYELIN SHEATH dysfunction) or axonal loss. The nerve and nerve sheath injuries may be caused by ISCHEMIA; INFLAMMATION; or a direct mechanical effect.
Stress is caused by your perception of situations around you and then the reaction of your body to them. The automatic stress response to unexpected events is known as 'fight or flight'. Discovered by Walter Cannon in 1932, it is the release of h...
