Collet-Sicard syndrome is a rare syndrome that involves paralysis of 9th to 12th cranial nerves. We report an uncommon case of schwannoma of the hypoglossal nerve in a 39-year-old woman presented with slurred speech, hoarse voice, and swallowing difficulty. Physical examination revealed decreased gag reflex on the right side, decreased laryngeal elevation, tongue deviation to the right side, and weakness of right trapezius muscle. MRI revealed a mass lesion in the right parapharyngeal space below the jugular foramen...

In the elderly, myasthenia gravis (MG) can present with bulbar symptoms, which can be clinically difficult to diagnose from other neurological comorbid conditions. We describe a case of a 75-year-old man who had been previously diagnosed with dysphagia associated with medullary infarction but exhibited aggravation of the dysphagia later on due to a superimposed development of bulbar MG. After recovering from his initial swallowing difficulties, the patient suddenly developed ptosis, drooling, and generalized weakness with aggravated dysphagia...

Byung-Ho Yoon, Jung Gon Kim, Yong-Chan Ha
Osteoid osteoma frequently requires surgical treatment, especially among young, active patients. However, surgeons are reluctant to perform open surgery for an osteoid osteoma of the femoral neck area because the conventional surgical approach requires a large incision in muscular patients, and percutaneous resection with a trephine has the attendant risk of subsequent fracture. Recently, arthroscopic excision of an osteoid osteoma has been reported as a less invasive, safer procedure than traditional open curettage...

OBJECTIVES: Arteriovenous malformations (AVMs) are complex vascular lesions. Surgical excision is the treatment of choice, but is often not achievable. Embolo-sclerotherapy alone is associated with high recurrence rates. This study tested the hypothesis that seeding hydrogel conditioned bone marrow derived mesenchymatous stem cells (BM-MSCs) in an AVM nidus model induces solid microvascular occlusion through endoluminal tissue growth. METHODS: AVMs were modelled as arteriovenous microvascular nidus, using swine rete mirabile, a plexiform intracranial structure composed of arterial microvessels that extensively anastomose...

A 53-year-old man presented with smooth-domed, variegated cysts (polycystic disease) of all 4 eyelids, worse on the left side. Some of the cysts were clear, while others were creamy-white colored. In addition, multiple, very fine vesicopapules were noted along the eyelid margins. Histopathologic examination revealed a trichilemmal cyst, several pure apocrine hidrocystomas displaying multiple chambers, a hybrid cyst, and many small eccrine cysts of the deep dermis. The apocrine lesions, including the small ones at the eyelid margins, predominated...

PURPOSE: To measure the thickness of the inferior oblique muscle (IOM) among Japanese by magnetic resonance imaging (MRI) using a new technique. METHODS: This retrospective observational study included 78 patients (36 males and 42 females) who underwent MRI for detection of a unilateral orbital lesion or examining causes of unilateral retrobulbar pain. The thickness of the IOM was measured on the side without the orbital lesion or symptom. On the quasi-sagittal plane through the optic nerve, the major and minor axes of the cross-section of the IOM were measured...

Background: Physical activity improves health, exercise tolerance and quality of life in adults with congenital heart disease (CHD), and exercise training is in most patients a high-benefit low risk intervention. However, factors that influence the confidence to perform exercise training, i.e. exercise self-efficacy (ESE), in CHD patients are virtually unknown. We aimed to identify factors related to low ESE in adults with CHD, and potential strategies for being physically active. Methods: Seventy-nine adults with CHD; 38 with simple lesions (16 women) and 41 with complex lesions (17 women) with mean age 36...

Pulmonary hypertension describes a heterogeneous disease defined by increased pulmonary artery pressures, and progressive increase in pulmonary vascular resistance due to pathologic remodeling of the pulmonary vasculature involving pulmonary endothelial cells, pericytes, and smooth muscle cells.  This process occurs under various conditions, and though these populations vary, the clinical manifestations are the same: progressive dyspnea, increases in right ventricular (RV) afterload and dysfunction, RV-pulmonary artery uncoupling, and right-sided heart failure with systemic circulatory collapse...

We report a rare case of Epstein-Barr virus (EBV)-positive polymorphic B-cell lymphoproliferative disorder (LPD) involving the lacrimal gland of a 28-year-old, apparently immunocompetent woman. She presented with a chief complaint of orbital swelling and tenderness and was found to have a lesion involving the right lacrimal gland and distal superior and lateral rectus muscles. Histology of the lesion revealed histiocytes with pleomorphic nuclei, reactive lymphocytes, and scattered cells that resembled the Reed-Sternberg (R-S) cells of classical Hodgkin lymphoma...

We present a 27-year-old male patient with neurofibromatosis type 2 (NF2), facial palsy, and lagophthalmos following acoustic neuroma removal and an impressing vascularized corneal tumor, which was excised. Histology showed a fibrous tumor with small vessels, and immunohistochemistry was positive for vimentin and negative for smooth muscle actin, S100, and GFAP. We assume a corneal myofibroma (keloid), which in this case rather represents a reactive lesion. This entity has not been described before in NF2 or in facial palsy-associated lagophthalmos in general...

REVIEW

Understanding the contribution of vascular cells to blood vessel remodeling is critical for the development of new therapeutic approaches to cure cardiovascular diseases (CVDs) and regenerate blood vessels. Recent findings suggest that neointimal formation and atherosclerotic lesions involve not only inflammatory cells, endothelial cells, and smooth muscle cells, but also several types of stem cells or progenitors in arterial walls and the circulation. Some of these stem cells also participate in the remodeling of vascular grafts, microvessel regeneration, and formation of fibrotic tissue around biomaterial implants...

BACKGROUND: Rotator cuff tears are believed to coexist with cervical spine lesions. In cases of preexisting neuropathy, such as cervical spine lesions, fatty degeneration has likely already occurred due to the neuropathy. In these cases, rotator cuff tear is thought to occur easily because of preexisting extensive fatty degeneration and degeneration of the tendons due to neuropathy. This study aimed to evaluate the effects of paralysis due to neuropathy proximal to the suprascapular nerve on the supraspinatus and infraspinatus tendons using a rat model of brachial plexus paralysis...

Atherosclerosis is characterized by the accumulation of lipids within the arterial wall. Although activation of TRPV1 cation channels by capsaicin may reduce lipid storage and the formation of atherosclerotic lesions, a clinical use for capsaicin has been limited by its chronic toxicity. Here we show that coupling of copper sulfide (CuS) nanoparticles to antibodies targeting TRPV1 act as a photothermal switch for TRPV1 signaling in vascular smooth muscle cells (VSMCs) using near-infrared light. Upon irradiation, local increases of temperature open thermo-sensitive TRPV1 channels and cause Ca2+ influx...
