BACKGROUND: Medication-related osteonecrosis of the jaw (MRONJ) is a severe adverse reaction experienced by some individuals to certain medicines commonly used in the treatment of cancer and osteoporosis (e.g. bisphosphonates, denosumab and antiangiogenic agents) and involves the progressive destruction of bone in the mandible or maxilla. Depending on the drug, its dosage, and the duration of exposure, the occurrence of this adverse drug reaction may be rare (e.g. following the oral administration of bisphosphonate or denosumab treatments for osteoporosis, or antiangiogenic agent-targeted cancer treatment) or common (e...

Minor salivary glands are relatively rare location for these tumors. Microscopically, they are composed of isomorphic cells, similar to basaloid cells with palisading arrangement and distinctive basement membrane like material. Herein, we report a case of BCApresenting as a soft tissue growth of left hard palate involving maxillary alveolus of a 41-year male.

Superior Thyroid Artery (STA) usually arises from the ventral surface of the External Carotid Artery (ECA) just below the level of tip of greater cornu of hyoid bone and it runs anteriorly, downwards and medially. Lingual artery arises at the level of tip of greater cornu of hyoid bone and it runs anteriorly, upwards and medially. Rarely, both STA and lingual artery may originate as a common trunk called thyrolingual trunk. But a thyrolingual trunk arising from Common Carotid Artery (CCA) is very rare. We report a case of patient diagnosed to have carcinoma of right lower alveolus with nodal recurrence; with thyrolingual trunk arising from the medial aspect of CCA, which was detected incidentally during neck dissection...

BACKGROUND: Recent studies indicate that recombinant human bone morphogenetic protein-2 (rhBMP-2) in a demineralized bone matrix scaffold is a comparable alternative to iliac bone autograft in the setting of secondary alveolar cleft repair. Postreconstruction occlusal radiographs demonstrate improved bone stock when rhBMP-2/demineralized bone matrix (DBM) scaffold is used but lack the capacity to evaluate bone growth in three dimensions. This study uses cone beam computed tomography to provide the first clinical evaluation of volumetric and density comparisons between these two treatment modalities...

BACKGROUND: The habit of inserting foreign objects into body cavities is seen in children and in adults with intellectual disability. Usually, the foreign objects cause chronic inflammation and local tissue destruction, which give rise to symptoms. Diagnosis at an asymptomatic stage is uncommon when the history is not suggestive. We describe a rare case where a foreign object was misdiagnosed as an odontoma in a patient with an alveolar cleft. CASE PRESENTATION: A radiopaque round mass was noted on the radiograph of a 12-year-old Sinhalese boy who was awaiting an alveolar bone graft...

Microparticles are a newly recognized class of mediators in the pathophysiology of lung inflammation and injury, but little is known about the factors that regulate their accumulation and clearance. The primary objective of our study was to determine whether alveolar macrophages engulf microparticles and to elucidate the mechanisms by which this occurs. Alveolar microparticles were quantified in bronchoalveolar fluid of mice with lung injury induced by LPS and hydrochloric acid. Microparticle numbers were greatest at the peak of inflammation and declined as inflammation resolved...

Calcifying epithelial odontogenic tumor (CEOT) is a rare, benign, odontogenic tumor arising from the odontogenic epithelium and accounts for approximately 1% of all odontogenic tumors. Clear cell variant of CEOT is a distinct entity and has more aggressive biological behavior and higher chances of recurrence. Here, we present a unique case of clear cell variant of CEOT involving the left side of the maxillary alveolus in a 73-year-old female patient with thorough clinical, radiological, and histological details...

Two cases of extralobar pulmonary sequestrations from a walrus (Odobenus rosmarus) and a Steller sea lion (Eumetopias jubatus) are described in the present study. Grossly, an independent, soft unilocular cystic mass was found within the abdominal cavities of both animals, adherent to the diaphragm in O. rosmarus and attached to the cardia of the stomach in E. jubatus. Histopathologically, the cysts were lined by pseudostratified ciliated columnar epithelium with abundant goblet cells, while the wall comprised of glands, hyaline cartilage, bronchiole- and alveolus-like structures, smooth muscles, and large, well-developed elastic and muscular arteries...

Myxofibrosarcoma (MFS) is a malignant fibroblastic tumor that primarily affects the lower and upper extremities. It is usually described as a slow-growing tumor with high recurrence rates but low metastatic potential. The reported incidence of head and neck MFS is 2 to 4% and rarely presents with distant metastases. This report describes a case of maxillary MFS in a 72-year-old woman whose disease progression followed an atypical course with an extremely rapid rate of growth and early pulmonary and central nervous system lesions...

Actinomycosis is an infrequent chronic infection regarded as the most misdiagnosed disease by experienced clinicians. The Office of Rare Diseases at the National Institute of Health has also listed this disease as a "rare disease." This article presents a case report of actinomycosis of the alveolus with unusual clinical features but a successful resolution. It also states the importance of biopsy of deceptive inflammatory lesions that do not respond or recur after conventional treatment modalities.

OBJECTIVE: Miniscrew-assisted rapid palatal expansion (MARPE) is a means for expanding the basal bone without surgical intervention in young adults. Here, we assessed the differences in dental, alveolar, and skeletal measurements taken before (T0), immediately after (T1), and 1 year after (T2) MARPE. METHODS: Twenty-four patients (mean age, 21.6 years) who had undergone MARPE and cone-beam computed tomography at T0, T1, and T2 were included. Changes in the following parameters were compared using paired t-tests: intercusp, interapex, alveolar, nasal floor, and nasal cavity widths; inclination of the first molar (M1) and its alveolus; and thickness and height of the alveolar bone...

INTRODUCTION: Isolated cleft lip is the mildest form of the cleft lip and palate spectrum; however those patients are often treated with the same surgical techniques that are used for the more severe cases (advancement-rotation flaps, quadrangular flaps). Meara's cheiloplasty technique may be a less aggressive option for lip repair in isolated cleft lip or whenever the gap between labial segments is not wide. MATERIAL AND METHODS: All children that had their cleft lip repaired following Meara's cheiloplasty between May 2014 and December 2015 were retrospectively reviewed...

BACKGROUND: Hypsodont equine cheek teeth possess large dental crowns, resting partly in the bony alveolus. Over a horse's life cheek teeth erupt continuously to compensate for occlusal wear of 3-4 mm per year. Parts of the crown initially resting in the bony alveolus become progressively exposed at the occlusal surface with time. Hitherto, it is unclear whether the typical structure of the equine occlusal surface, composed of a complex arrangement of enamel, dentin and cementum, remains constant or undergoes structural changes with age...

INTRODUCTION: The purpose of our study was to describe a novel technique for reconstruction of orbital defects after maxillectomy using a non-anatomic titanium mesh suspension of orbital contents for both support and volume correction. This construct is then articulated with a layered fibula osteocutaneous free flap that restores orbital rim, zygoma, and maxillary alveolus. We herein present our application of this technique, including refinements over time and long-term outcomes. METHODS: A retrospective review was performed on 12 patients who underwent reconstruction of Brown class III orbitopalatomaxillary defects with extensive orbital involvement (at minimum complete orbital floor and rim absent) with titanium mesh sling and a layered fibula free flap...

Oral clefts play an essential role in disturbed odontogenesis of the deciduous and permanent dentition, yet little is known about this relationship. We investigated, within the categories cleft lip with or without alveolus (CL ± A) and cleft lip, alveolus and palate (CLAP), whether different CL subphenotypes based on morphological severity of the cleft show different dentition patterns and whether a more detailed subdivision of the incomplete CL has clinical relevance. In this retrospective study, 345 children with nonsyndromic unilateral CL ± A and CLAP from the Dutch Association for Cleft Palate and Craniofacial Anomalies (NVSCA) registry were included to assess the association between the CL subphenotypes and lateral incisor patterns...

INTRODUCTION: Iliac crest is the most common donor site for autogenous bone grafting as cortical bone, cancellous bone or combination of both can be harvested in abundance depending upon the need. Ilium provides highest concentration of osteo-component cells and greater quality of bone with less morbidity. AIM: The study was conducted to evaluate the donor site morbidity associated with autogenous iliac crest bone grafting for reconstruction in maxillofacial surgery...

REVIEW
Jie Cai, Diming Wang, Jianxin Liu
Dairy milk consists of more than 85% water. Therefore, understanding the regulation of fluid absorption in the mammary gland is relevant to improving milk production. In recent decades, studies using different approaches, including blood flow, transmembrane fluid flow, tight junction, fluid flow of the paracellular pathway and functional mammary epithelial cell state, were conducted to investigate how mammary gland fluid absorption was regulated. However, the relationship between regulation mechanisms of fluid flow and milk production has not been studied systematically...

Acute dyspnea is a frequent cause of access to the Discharge Department (DEA); Differentiation between cardiogenic and respiratory causes does not always seem simple and certain, causing a delay in initiating targeted therapies and prolonging the Patient's stay in the emergency department. The basic elements for the diagnosis remain the history and the objective examination, supplemented by the execution of an electrocardiogram, a determination of blood parameters and the execution of a chest X-ray. The limits of radiological semeiotics, related to a low sensitivity to high specificity, promote other methods available to the physician of First Aid...

BACKGROUND: Clefts of the lip and/or palate (CL/P) carry a social stigma that often causes psychosocial stress. The purpose of this study was to consider the association of cleft phenotype and age with self-reported aspects of psychosocial stress. METHODS: Children with nonsyndromic CL/P and unaffected children born between 1997 and 2003 were identified through the North Carolina Birth Defects Monitoring Program and North Carolina birth records, respectively. The psychosocial concerns of children with CL/P were assessed via a 29-question subset of a larger survey...
