A classification for peri-implant diseases and conditions was presented. Focused questions on the characteristics of peri-implant health, peri-implant mucositis, peri-implantitis, and soft- and hard-tissue deficiencies were addressed. Peri-implant health is characterized by the absence of erythema, bleeding on probing, swelling, and suppuration. It is not possible to define a range of probing depths compatible with health; Peri-implant health can exist around implants with reduced bone support. The main clinical characteristic of peri-implant mucositis is bleeding on gentle probing...

BACKGROUND: Although a simple bone cyst carries the risk of pathological fractures, it rarely causes severe deformity. Here we report a case of severe femoral deformity after multiple pathological fractures due to simple bone cysts, and consider the reason for the progression of malunion despite multiple previous treatments. Finally, we propose a treatment option for malunion correction. CASE PRESENTATION: A 9-year, 7-month-old Japanese girl was referred to our facility with obvious deformity of her right femur, caused by multiple simple bone cyst-related pathological fractures...

RATIONALE: We report two rare cases of enchondroma protuberans originating from phalanxes. PATIENT CONCERNS: The patients visited doctors for a palpable mass in their phalanx without any pain or discomfort. DIAGNOSES: Biopsy is the gold standard for the diagnosis of enchondroma protuberans. Radiographs usually provide important imaging information, while studied on the ultrasound manifestation of enchondroma protuberans are still limited. In our cases, significant information about ultrasound manifestation of enchondroma protuberans were presented...

RATIONALE: Pheochromocytomas are rare catecholamine-secreting tumors arising from adrenomedullary chromaffin cells, usually causing hypertension, palpitation and headache. However, pheochromocytoma crisis, on the contrary, might present with hypotension, multiple organ dysfunction or even mimicking other diseases, leaving physician with diagnostic difficulties. In this study, we present a case featured hypotension, shock and multiple organ dysfunction syndrome on admission, which nearly lead us to miss the diagnosis of pheochromocytoma...

Background The presence of high blood flow in the structurally abnormal and painful regions of tendinosis, but not in the normal pain-free tendons, was recently confirmed by colour Doppler (CD) ultrasound (US). Biopsies from the regions with high blood flow demonstrated the presence of sympathetic and sensitive nerve fibres juxtapositioned to neovessels. Grey-scale US and CD are reliable methods used to evaluate structural homogeneity, thickness, and blood flow in the peripheral tendons. The aim of this study was to utilize CD to qualitatively evaluate for the presence of abnormal high blood flow in paravertebral tissues after whiplash injuries in patients with chronic neck pain...

Evaluation of a hand mass and subsequent surgical treatment is a frequent clinical encounter for the practicing hand surgeon. The clinical evaluation of benign and malignant hand tumors has traditionally focused on diagnosis, surgical excision, and reconstruction. There is a paucity of literature discussing the determining factors for a hand mass biopsy, its appropriate technique, and postbiopsy preparation and handling. This review discusses the approaches of the hand surgeon and orthopedic oncologist to a soft tissue mass in the hand and clarifies the term biopsy...

We describe a case of a 57-year-old man referred to an oral maxillofacial surgeon for a nontender, large intramuscular tongue mass. A computed tomography scan with contrast showed a homogenous right tongue intramuscular fatty mass measuring 3.8 cm × 2.8 cm in the axial dimension and 2.2 cm in the craniocaudal dimension. Histologic examination revealed multiple lobulated sections of mature adipocytes and occasional entrapped skeletal muscle fibers. The final pathologic diagnosis was intramuscular lipoma...

CONTEXT: Inflammatory myofibroblastic tumors are a rare type of soft-tissue tumor. Inflammatory myofibroblastic tumors are characterized by rearrangements involving the anaplastic lymphoma kinase gene locus on 2p23. CASE REPORT: We report the case of a 67-year-old Chinese male who presented with dysuria and fever. Magnetic resonance imaging showed an irregular prostatic mass with an isointense signal and obscure boundary. Histopathological evaluation showed that the mass consisted mainly of spindle-shaped cells...

Fluorosis can induce oxidative stress through leading to reactive oxygen species (ROS) generation. Selenium (Se) can eliminate ROS by direct and indirect manners. In this study, therefore, we investigated the possible protective effects of sodium selenite (SS) and selenomethionine (Se-Met) on fluorine (F)-induced oxidative stress in broilers. A total of 720 1-day-old Lingnan Yellow broilers were allotted to 4 groups (6 replicates of 30 birds each group) and fed with basal diet (control group), 800 mg/kg F (high F group), 800 mg/kg F+0...

The last 25 years have brought significant progress in the treatment of sarcomas in children, especially rhabdomyosarcoma (RMS). Nevertheless, treatment failure in some patients results from considerable biological heterogeneity noted in these tumours. RMS, the most common malignant soft tissue neoplasm in children, includes two main subtypes: embryonal (ERMS) and alveolar (ARMS). Due to greater aggressiveness and worse prognosis of ARMS in comparison to ERMS, discrimination between different rhabdomyosarcoma subtypes is of crucial clinical importance...

BACKGROUND: Chronic osteomyelitis associated with a stage IV decubitus ulcer is a challenging condition to manage, characterized by frequent relapses and need for long-term anti-microbial therapy. Although gram-positive cocci are the most common causes, fungal infections have been reported, usually in immunocompromised hosts. We present a case of Cladophialophora osteomyelitis in a patient without known immunocompromised that was managed with a Girdlestone pseudoarthroplasty. CASE REPORT: A 70-year-old male presented to our emergency room with fever, right hip pain, and purulent drainage from a right greater trochanter stage IV decubitus ulcer...
