Parental perception of oral health-related quality of life in children with autism. An observational study.

Background: Autism is reportedly the most severe neuropsychiatric disorder affecting children. Autistic subjects can be characterized by impairments in social interactive behavior along with restricted interests and quite frequently, are seen exhibiting repetitive behavior patterns in stereotyped manner. The inability to perform routine tasks can widely impact the oral health and also, the constant care and sense of helplessness might drastically affect quality of life.

Nanodiamonds as a state-of-the-art material for enhancing the gamma radiation resistance properties of polymeric membranes.

We report, for the first time, the development of gamma radiation resistant polysulfone (Psf)-nanodiamond (ND) composite membranes with varying concentrations of NDs, ranging up to 2 wt% of Psf. Radiation stability of the synthesized membranes was tested up to a dose of 1000 kGy. To understand the structure-property correlationship of these membranes, multiple characterization techniques were used, including field-emission scanning electron microscopy, atomic force microscopy, drop shape analysis, Fourier-transform infrared spectroscopy, X-ray photoelectron spectroscopy, gel permeation chromatography, positron annihilation spectroscopy, and small angle X-ray scattering.

Torque ripple reduction of Induction Motor using Dynamic Fuzzy Prediction Direct Torque Control.

This paper presents a Dynamic Fuzzy Logic based Prediction Direct Torque Control (DFL-PDTC) technique to reduce torque ripples within the squirrel cage induction motor (SCIM). This DFL and PDTC combination reduces the high amount of torque ripple and improves the starting conditions in both low& high mechanical speeds of the motor. The Induction Motor (IM) is used mainly in industrial applications due to its limited size and self-starting performance than other motors.

Mixed-matrix membranes with enhanced antifouling activity: probing the surface-tailoring potential of Tiron and chromotropic acid for nano-TiO.

Mixed-matrix membranes (MMMs) were developed by impregnating organofunctionalized nanoadditives within fouling-susceptible polysulfone matrix following the non-solvent induced phase separation (NIPS) method. The facile functionalization of nanoparticles of anatase TiO (nano-TiO) by using two different organoligands, . Tiron and chromotropic acid, was carried out to obtain organofunctionalized nanoadditives, F-nano-TiO and F-nano-TiO, respectively.

Evidence based solving approach in diagnosis of primary hyperparathyroidism with oral manifestations: report of three unusual cases.

Primary hyperparathyroidism is a common condition that affects 0.3% of the general population in which excessive production of PTH is there. With changing trends it is diagnosed early and asymptomatically with the improvements in routine biochemical tests and radiological procedures.

Current concepts in diagnosis of unusual salivary gland tumors.

Salivary gland tumors are relatively uncommon and account for approximately 3-6% of all neoplasms of the head and neck. Tumors mostly involve the major salivary glands, 42.9-90% of which occur in the parotid glands and 8-19.

Amelogenin: A novel protein with diverse applications in genetic and molecular profiling.

Tooth enamel is a unique entity among all mineralized tissues because of the presence of high mineral content. It is non collagenous and does not undergo resorption and remodelling. Its formation occurs through a transient collaborating network of enamel matrix proteins which controls hydroxyapatite crystal growth and orientation.

Primary oral malignant melanoma: Clinicopathological series of four cases.

Melanoma of the oral cavity is a rare malignant disease. On account of the presence at relatively obscure areas in the oral cavity, most of oral malignant melanomas are diagnosed at a late stage. Early diagnosis is essential for successful treatment and perhaps is the key factor in improving the prognosis of oral malignant melanoma.

Rare occurrence of intraosseous schwannoma in a young child, its review and its pathogenesis.

Schwannoma is a benign, encapsulated, perineural tumor that arises from the Schwann cells. Approximately 25% of the reported cases originate from the head and neck region. Of these, approximately 1-12% occurs intraorally.

Surgeon and patient radiation exposure in minimally invasive transforaminal lumbar interbody fusion.

Object: Minimally invasive transforaminal lumbar interbody fusion (TLIF) is an increasingly popular procedure. The technique involves use of fluoroscopy to assist with pedicle screw (PS) placement. The potential exists for both the surgeon and the patient to become exposed to significant amounts of radiation.

Resorbable anterior cervical plates for single-level degenerative disc disease.

Objective: Resorbable spinal implants have generated increasing interest. There are minimal data in the literature on the use of resorbable anterior cervical plates. The purpose of this study is twofold.

Intraoperative electromyography monitoring in minimally invasive transforaminal lumbar interbody fusion.

Object: Minimally invasive transforaminal lumbar interbody fusion (TLIF) is an increasingly popular method for achieving lumbar decompression and fusion. The procedure is technically more demanding than open fusion, with correspondingly more theoretical risk of complication. The authors describe the use of intraoperative electromyography (EMG) as an adjunct to surgery to reduce the risk of complications.

The natural history of untreated skull base meningiomas.

Background: This study was undertaken to determine the natural history of untreated skull base meningiomas. Although there are reports on the natural history of meningiomas, most series contain only a few cases of meningiomas involving the skull base. Natural history information is important when recommending treatment and evaluating results.

Femoral ring allograft for anterior cervical interbody fusion: technical note.

Objective: Cadaveric fibula with locking plate internal fixation has been reported to be associated with fewer complications and better long-term results, compared with autologous iliac crest. With the knowledge that cortically dense allografts collapse less with time, new machined femoral ring allografts were developed for anterior cervical fusion after anterior cervical discectomy. We describe the system and the technique for placement.

IMPORTANCE OF PROSTATIC SPECIFIC ANTIGEN (PSA) IN CLINICAL PRACTICE : OUR EXPERIENCE.

A total of 89 patients in the age group of 50-92 years having different histopathologically proven prostatic conditions were analysed with prostate specific antigen (PSA) and clinical co-relation undertaken. PSA levels were found to be significantly higher (p < 0.05) in 48 carcinoma prostate cases (mean 93.

Surgery versus radiosurgery in the treatment of brain metastasis.

Surgery and radiosurgery are effective treatment modalities for brain metastasis. To compare the results of these treatment modalities, the authors followed 13 patients treated by radiosurgery and 62 patients treated by surgery who were retrospectively matched. Patients were matched according to the following criteria: histological characteristics of the primary tumor, extent of systemic disease, preoperative Karnofsky Performance Scale score, time to brain metastasis, number of brain metastases, and patient age and sex.

Surgical treatment of metastatic brain tumors.

The most common structural neurologic complication of systemic cancer is brain metastasis. For the most part, treatment is palliative because the majority of patients (> or = 50%) have uncontrollable systemic cancer. However, for patients in whom the only metastasis is to the brain, death is more likely to result from the metastasis than from the systemic disease; hence, treatment of the metastasis is vitally important.

Reoperation for recurrent metastatic brain tumors.

Results of reoperation in 48 patients who developed recurrent brain metastases between January 1984 and April 1993 are presented. Median time from first craniotomy to diagnosis of recurrence (time to recurrence) was 6.7 months.

Management of intracranial plasmacytoma.

The authors report on a study of eight cases of intracranial plasmacytoma to identify the risk of progression to multiple myeloma and suggest the treatment required for cure of solitary lesions. The diagnosis of multiple myeloma or myelomatous changes was made in the immediate postoperative period in four patients (50%), two of whom had skull base lesions. Of the four remaining patients, three were treated with complete surgical resection and radiation therapy and had no recurrence of plasmacytoma or progression to multiple myeloma during mean follow up of 12 years (range 2-25 years); one patient underwent subtotal surgical resection and had recurrence of the tumor despite radiation therapy.
