Introduction: Gated tangential field-in-field (FIF) technique is used to lower the dose to organs at risk for breast cancer radiotherapy (RT). In this study, the authors investigated the accuracy of the delivered treatment plan with and without gating using a two-dimensional detector array for patient-specific verification purposes.Methods: In this study, a 6MV beams were used for the merged FIF RT (forward Intensity Modulated Radiation Therapy). The respiration signals for gated FIF delivery were obtained from the one-dimensional moving phantom using the real-time position management (RPM) system (Varian Medical Systems, Palo Alto, CA). RPM system used for four-dimensional computed tomography scanner light-speed, GE is based on an infrared camera to detect motion of external 6-point marker. The beams were delivered using a Clinac iX (Varian Medical Systems, Palo Alto, CA) with the multileaf collimator Millennium 120. The MapCheck2 (SunNuclear, Florida) was used for the evaluation of treatment plans. MapCheck2 was validated through a comparison with measurements from a farmer-type ion chamber. Gated beams were delivered using a maximum dose rate with varying duty cycles and analyzed the MapCheck2 data to evaluate treatment plan delivery accuracy.Results: Results of the gamma passing rate for relative and absolute dose differences for all ungated and gated beams were between 95.1% and 100%.Conclusion: Gated FIF technique can deliver an accurate dose to a detector during gated breast cancer RT. There is no significance between gated and ungated patient-specific quality assurance (PSQA); one can use ungated PSQA for verification of treatment plan delivery

Voice Use

PurposeVocal fold motion impairment (VFMI) can be the result of iatrogenic or traumatic injury or may be idiopathic in nature. It can result in glottic incompetence leading to changes in vocal quality and ease. Associated voice complaints may include breathiness, roughness, diplophonia, reduced vocal intensity, feeling out of breath with talking, and vocal fatigue with voice use. A comprehensive interprofessional voice evaluation includes auditory-perceptual voice evaluation, laryngeal examination including videostroboscopy, acoustic and aerodynamic voice measures. These components provide valuable insight into laryngeal structure and function and individual voice use patterns and, in conjunction with stimulability testing, help identify candidacy for voice therapy and choice of therapeutic techniques.ConclusionA comprehensive, interprofessional evaluation of patients with VFMI is necessary to assess the role of voice therapy and develop a treatment plan. Although there is no efficacy data to support specific voice therapy techniques for treating VFMI, considerations for various techniques are provided.

Abstract A diagnosis of toxic-related injury/illness requires a consideration of the illness related to the toxic exposure, including diagnosis, causation, and permanent impairment; these are best performed by a physician who is certified by a specialty board certified by the American Board of Preventive Medicine. The patient must have a history of symptoms consistent with the exposure and disease at issue. In order to diagnose the presence of a specific disease, the examiner must find subjective complaints that are consistent with the objective findings, and both the subjective complaints and objective findings must be consistent with the disease that is postulated. Exposure to a specific potentially causative agent at a defined concentration level must be documented and must be sufficient to induce a particular pathology in order to establish a diagnosis. Differential diagnoses must be entertained in order to rule out other potential causes, including psychological etiology. Furthermore, the identified exposure at the defined concentration level must be capable of causing the diagnosis being postulated before the examiner can conclude that there has been a cause-and-effect relationship between the exposure and the disease (dose-response relationship). The evaluator's opinion should make biological and epidemiological sense. The treatment plan and prognosis should be consistent with evidence-based medicine, and the rating of impairment must be based on objective findings in involved systems.

Frequent Problem

The diabetic ischaemic foot has become an increasingly frequent problem over the last decade. However, we report a new approach consisting of a basic classification, a simple staging system of the natural history and a treatment plan for each stage, within a multi-disciplinary framework. This approach of "taking control" consists of two parts: 1. long-term conservative care including debridement of ulcers (to obtain wound control), eradication of sepsis (micribiological control), and provision of therapeutic footwear (mechanical control), and 2. revascularisation by angioplasty and arterial bypass (vascular control). This approach has led to a 50% reduction in the rate of major amputations in patients attending with ischaemic ulceration and absent foot pulses from 1989 to 1999 (from 4.6% to 2.3% per year). Patients who underwent angioplasty increased from 6% to 13%. Arterial bypass similarly increased from 3% to 7% of cases. However, even with an increased rate of revascularisation, 80% of patients responded to conservative care alone. This,we conclude, is an essential part of the management of all patients with ischaemic feet.

Abstract:The monitoring and treatment of patients in a care unit is a complex task in which even the most experienced clinicians can make errors. A hemato-oncology department in which patients undergo chemotherapy asked for a computerized system able to provide intelligent and continuous support in this task. One issue in building such a system is the definition of a control architecture able to manage, in real time, a treatment plan containing prescriptions and protocols in which temporal constraints are expressed in various ways, that is, which supervises the treatment, including controlling the timely execution of prescriptions and suggesting modifications to the plan according to the patient’s evolving condition. The system to solve these issues, called SEPIA, has to manage the dynamic, processes involved in patient care. Its role is to generate, in real time, commands for the patient’s care (execution of tests, administration of drugs) from a plan, and to monitor the patient’s state so that it may propose actions updating the plan. The necessity of an explicit time representation is shown. We propose using a linear time structure towards the past, with precise and absolute dates, open towards the future, and with imprecise and relative dates. Temporal relative scales are introduced to facilitate knowledge representation and access.

Gummy Smile

A healthy and beautiful smile can affect appearance and confidence. One of the aesthetic problems in dentistry that is often complained of by patients is excessive gingival display (gummy smile). The excessive gingival display can be caused by several factors, one of which is altered passive eruption (APE). One of the treatments to correct gummy smile related to APE is crown lengthening. Crown lengthening can be with bone reduction (gingivectomy with bone reduction) or without bone reduction (gingivectomy). Crown Lengthening with bone reduction is a surgical procedure that aims to maintain the dentogingival complex and to improve smile aesthetics. The purpose of this case report is to determine the crown lengthening with bone reduction (gingivectomy with bone reduction) procedure as a gummy smile treatment related to APE .A23-year-old female patient, came to Dental Hospital of Universitas Airlangga with complaints of her upper gum which not in the same length and the teeth looked short, she considered her smile was less aesthetic. After conducting analyses relating to aesthetics and periodontal tissue, crown lengthening with bone reduction was chosen for this patient treatment. The treatment results are quite good, visible gingival margins that matched the gingival zenith and improved patient's smile profile. APE as the etiology of patient's gummy smile can be corrected. There are no post-surgical complications such as excessive pain and infection. A proper diagnosis, treatment plan, and good techniques can produce a harmonious smile on the patient.
