#1
T Fattahi, S Salman, B Steinberg
Mid-face augmentation via a Le Fort I osteotomy is a commonly performed operation. Advancement of the upper jaw and associated structures (nose, lower cheek areas) can certainly improve function as well as facial aesthetics and harmony. Often, in patients with severe mid-face deficiency, hypoplasia of the maxilla extends all the way up to the infraorbital rims. The receding infraorbital rim contributes to the negative vector of the globes. In patients with this level of mid-face hypoplasia, while advancing the maxilla at the Le Fort I level satisfies all of the requirements for orthognathic surgery, the deficient infraorbital rim remains unchanged and can actually accentuate the negative vector of the globes...

Introduction - The caseload of jaw osteomyelitis seem to have decreased considerably over the last fifty years thanks to the progress of oral hygiene, the appearance and the use of antibiotics, and early screening. 'Limited osteitis' remains frequent in general practice (alveolitis after dental extraction), but osteomyelitis is much rarer as evidenced by the lack of current literature and the low number of reported patients in the published series. The aim of this study was to analyze retrospectively all the cases of maxillo-mandibular osteomyelitis treated in a large academic department of Stomatology and Maxillofacial Surgery over a period of 6 years and to compare the results to data from the literature...

The interaction between platelets and monocytes plays a critical role in the pathogenesis and progression of cardiovascular diseases. This study investigated how short-term intensive training (SIT) influences monocyte subset characteristics and exercise-induced monocyte and platelet aggregates (MPAs) following elective coronary bypass (CABG) in cardiac patients. Forty-nine patients hospitalised for CABG were randomised into SIT (N=26) and conventional training (CT, N=23) groups. The SIT subjects underwent supervised aerobic training at 80~120 % of the ventilatory anaerobic threshold based on sub-maximal exercise tests performed 7 days post-CABG for 20 sessions with two sessions/day and 30 min/session, which were completed within four weeks after surgery...

Primary intraosseous odontogenic squamous cell carcinoma (PIOSCC) is a rare tumor. The incidence is low, and approximately 200 cases are reported in literature. The etiology is associated with the malignant degeneration of embryological remains. Differential diagnosis includes alveolar carcinomas, jaw metastases from other locations, odontogenic tumors, and tumors of the maxillary sinus. However, the diagnosis could be delayed due to the absence of symptoms in early stages. Surgery represents the first choice treatment...

Osteopetrosis (OP) comprehends a rare group of conditions, presenting on radiographs increased bone density, deriving from irregularities in osteoclast differentiation or function. In the autosomal dominant osteopetrosis (ADO), some patients stay asymptomatic for some time, or only develop mild symptoms. The dental surgeon is often the first to presuppose the disease during routine imaging examinations, referring the patient to a specialized medical group. Furthermore, osteomyelitis is one of the major OP complications, and should be refrained through frequent dental monitoring...

Giant cell tumor (GCT) of the craniofacial bones has been reported but they are not common. This tumor occurs more often in women than in men and predominantly affects patients around the third to fifth decade of life. GCTs are generally benign but can be locally aggressive as well. We report a case of GCT involving the temporomandibular joint (TMJ), which was initially thought to be temporomandibular disorder (TMD). A 22-year-old female presented with swelling and pain over the right temporal region for 18 months associated with jaw locking and clicking sounds...

Orocutaneous fistula (OCF) of dental origin is a relatively rare condition and continues to be a challenging diagnosis. Misdiagnosis of OCF usually leads to unnecessary and noneffective treatment. A 21-year-old male referred with a complaint of a lesion on the chin which was misdiagnosed as a carbuncle (lesion of nonodontogenic origin) by a physician. After radiological examination, there was a lesion around the apical region of right central incisor. These findings indicated a sinus tract associated with dental origin...

Endocrine tumors of thyroid, adrenal and parathyroid glands may be due to germline and inheritable mutations in 5-30% of patients. Medullary Thyroid Carcinoma, Pheochromocytoma, Paraganglioma, and Familial Primary Hyperparathyroidism are the most frequent entity. Hereditary endocrine tumors usually have a suggestive familial history; they occur earlier than sporadic variants, are multifocal, and have increased recurrence rates. They may be present as isolated variant or associated to other neoplasms in a syndromic setting...
