Oral cancer, especially that originates in the maxillary tuberosity, buccal mucosa, and maxillary alveolus, is apt to invade the pterygopalatine fossa, where an intraoral approach is nearly impossible. There are 2 main types of extraoral approach to the pterygopalatine fossa; the anterior approach and the lateral approach. Although the lateral approach has an advantage compared with the anterior approach in terms of cosmetics, after the operation numbness of the lower lip occurs due to the sacrifice of the mental nerve...

Methylmalonic acidemia (MMA) is the most common organic acidemia in childhood. Many "treated" patients continued to display various degrees of mental retardation and psychomotor delay, which could be caused by brain damage from elevated oxidative stress. Aminoguanidine (AG), a synthetic antioxidant, was tested in a MMA rat model for its potential therapeutic effects on memory impairment. The effects of AG on MMA-induced cognitive impairment in Wistar rats were evaluated with Morris Water Maze. The levels of nerve cell apoptosis and microglial activation were investigated to illustrate the mechanisms of the improvement of cognition with AG treatment in MMA rats...

BACKGROUND: Accessory mental foramen (AMF) is a rare anatomical variation. When accessory mental foramen is present, the nerves and vessels that go through the mental foramen (MF) must follow alternative courses and special care must be taken during dental treatment planning. The purpose of this study was to evaluate the occurrence and the location of AMF in a selected Polish population using cone-beam computed tomography (CBCT). METHODS: Two hundred CBCT (105 males and 95 females) examinations were evaluated for the presence of AMFs...

The purpose of the present study was to investigate the long-term effect of deep infection, sural nerve injury, and repeat rupture in the treatment of acute Achilles tendon rupture. A total of 324 patients had made a claim to the Danish Patient Insurance Association from 1992 to 2010 for a complication after acute Achilles tendon rupture. Of the 324 patients, 119 (77 males and 42 females) returned the Achilles tendon total rupture score and the 36-item short-form survey questionnaires. Patients with deep infection (n = 10), sural nerve injury (n = 10), and repeat rupture (n = 16) participated in a follow-up investigation...

Inflammatory bowel disease is a group of chronic medical conditions comprising Crohn's disease and ulcerative colitis that involves increased frequency of mental disorders. The most common psychiatric disorders in inflammatory bowel disease are depression and anxiety, however, some epidemiologic and biological evidence suggest that other disorders like bipolar disorder occur more often. Biological mechanisms concerning both inflammatory bowel disease and depression or anxiety explain susceptibility to developing mental disorders in inflammatory bowel disease...

Neuropathy target esterase (NTE) or patatin-like phospholipase domain containing 6 (PNPLA6) was first linked with a neuropathy occurring after organophosphate poisoning and was later also found to cause complex syndromes when mutated, which can include mental retardation, spastic paraplegia, ataxia, and blindness. NTE/PNPLA6 is widely expressed in neurons but experiments with its Drosophila orthologue Swiss-cheese (SWS) suggested that it may also have glial functions. Investigating whether NTE/PNPLA6 is expressed in glia, we found that NTE/PNPLA6 is expressed by Schwann cells in the sciatic nerve of adult mice with the most prominent expression in nonmyelinating Schwann cells...

The bilateral sagittal split mandibular osteotomy (BSSMO), a common maxillofacial technique for expanding the oropharynx during treatment of micrognathia, is a rarely employed but useful adjunct to improve surgical access to the ventral cervical spine in children. Specifically, it provides enhanced exposure of the craniocervical junction in the context of midface hypoplasia, and of the subaxial cervical spine in children with severe kyphosis. The authors describe their technique for BSSMO and evaluate long-term outcomes in patients...

An approximately 3,000 finishing swine operation in the United States experienced an outbreak of an atypical neurologic disease in 11-weeks-old pigs with an overall morbidity of 20% and case fatality rate of 30%. The clinical onset and progression of signs in affected pigs varied but included inappetence, compromised ambulation, ataxia, incoordination, mental dullness, paresis, paralysis and decreased response to environmental stimuli. Tissues from affected pigs were submitted for diagnostic investigation. Histopathologic examination of the cerebrum, cerebellum and spinal cord revealed severe lymphoplasmacytic and necrotizing polioencephalomyelitis with multifocal areas of gliosis and neuron satellitosis, suggestive of a neurotropic viral infection...

BACKGROUND: Post-operative cognitive impairment is common in elderly patients following surgery for hip fracture, with undertreated pain being an important etiological factor. Non-opioid based analgesic techniques, such as nerve blocks, may help reduce the risk of cognitive complications. The aim of this study was to investigate whether receiving a fascia iliaca compartment block (FICB) as part of a pre-operative analgesic regime increased the odds of high post-operative abbreviated mental test scores (AMTS) when compared with conventional analgesia without a nerve block...

Mandibular contouring surgery was performed using computer-assisted simulation planning (CASP) and 3-dimensional printed surgical guide. The outcome of the surgery was evaluated by overlapping preoperative image. The patient underwent mandibular contouring surgery according to CASP for his residual facial asymmetry of the mandibular angle and mental area. The overall facial aesthetic of the patient was improved. In the overlapping image, the left mandibular border area was slightly overcorrected. However, the other portion was operated as planned...

BACKGROUND: Alzheimer's disease (AD) and frontotemporal dementia (FTD) are leading causes of cognitive decline. Optical coherence tomography (OCT) allows the measurement of thickness of retinal neuroaxonal layers. While in AD and mild cognitive impairment (MCI), retinal nerve fiber layer (RNFL) thinning is frequently reported, less information is available on ganglion cell layer-inner plexiform layer (GCL-IPL). Data on FTD are lacking. OBJECTIVE: To obtain cross-sectional information on RNFL and GCL-IPL thickness among MCI, AD, FTD, and healthy controls (HC), and their correlations with dementia severity...

Mental nerve (MN) injury is the most common complications of genioplasty; to protect the MN and oral mucosa, the authors invent and validate the appropriate retractors for genioplasty, and which can avoid the skin and mucous membrane of the lower lip, chin, and the vestibular gingiva of the mandibular incisor from paresthesia or dysesthesia. The patent application for the appropriate retractors for genioplasty is already submitted (Patent No 201610164563.3, China). The retractors provide a better surgical visual field and improve the operation efficiency while reducing the risk of surgery...

Nerve growth factor (NGF) is an important member of the neurotrophin family and its alteration has been associated with psychiatric disorders. Functionality consists of the activities that an individual can perform, as well as their social participation, which is an important factor in analyzing the carrier living conditions of subjects with psychiatric suffering. Several studies have evaluated functionality in bipolar disorder; however, no studies have evaluated the functionality in other mental disorders...

Numb chin syndrome (NCS) is a rare yet potentially ominous sensory neuropathy in the distribution of the mental or inferior alveolar nerve characterized by unilateral hypoesthesia over the lower lip, chin and occasionally gingival mucosa. Recognizing NCS is clinically important as this may be a subtle sign of occult malignancy progression or heralding the relapses. It may also occur in benign disease, both systemic and dental in origin. Current expert opinion is that patients with NCS without apparent cause should be assumed to have a malignant etiology until proven otherwise Lossos and Siegal (1992) [1]...
