چکیده

tiated by a psychiatrist.” Aripiprazole and quetiapine are both approved by the US Food and Drug Administration for augmentation pharmacotherapy of major depressive disorder. Given a shortage of psychiatrists, and wait times of up to 3 months to see a psychiatrist, and in an age when psychiatric disorders are the leading source of medical disability, it is imperative for primary care physicians to learn how to safely use any and all available interventions, including the appropriate use and monitoring of atypical antipsychotics.

Dosimetric comparison of 3-dimensional conformal and intensity-modulated radiotherapy techniques for whole breast irradiation in the prone and supine positions

Background: The aim of this study was to compare the differences of the dosimetric parameters between three-dimensional conformal radiotherapy (3D-CRT) and simultaneous-integrated boost intensity-modulated radiotherapy (SIB-IMRT) techniques in the prone and supine positions for breast irradiation. Materials and Methods: Ten patients underwent a computed tomography simulation in both the prone a...

Radiation dose to the nodal regions during prone versus supine breast irradiation

BACKGROUND Prone positioning for breast radiotherapy is preferable when the aim is a reduction of the dose to the ipsilateral lung or the heart in certain left-sided cases. MATERIALS AND METHODS In 100 breast cancer cases awaiting postoperative whole-breast radiotherapy, conformal radiotherapy plans were prospectively generated in both prone and supine positions. The axillary nodal region (le...

Prone versus supine positioning for whole and partial-breast radiotherapy: a comparison of non-target tissue dosimetry.

PURPOSE To compare non-target tissue (including left-anterior-descending coronary-artery (LAD)) dosimetry of prone versus supine whole (WBI) and partial-breast irradiation (PBI). METHODS AND MATERIALS Sixty-five post-lumpectomy breast cancer patients underwent CT-imaging supine and prone. On each dataset, the whole-breast clinical-target-volume (WB-CTV), partial-breast CTV (tumour-bed + 15 mm...

Prone breast forward intensity-modulated radiotherapy for Asian women with early left breast cancer: factors for cardiac sparing and clinical outcomes

Since December 2009, after breast-conserving surgery for Stage 0-I cancer of the left breast, 21 women with relatively pendulous breasts underwent computed tomography prone and supine simulations. The adjuvant radiotherapy was 50 Gy in 25 fractions to the left breast alone. Four plans--conventional wedged tangents and forward intensity-modulated radiotherapy (fIMRT) in supine and prone position...

Breast radiotherapy in the prone position primarily reduces the maximum out-of-field measured dose to the ipsilateral lung.

PURPOSE To quantify the potential advantages of prone position breast radiotherapy in terms of the radiation exposure to out-of-field organs, particularly, the breast or the lung. Several dosimetric studies have been reported, based on commercial treatment planning software (TPS). These TPS approaches are not, however, adequate for characterizing out-of-field doses. In this work, relevant out-o...

Evaluation of incidence of intestinal complications during radiation therapy in two supine and prone positions in patients with rectal cancer

Introduction: Radiation therapy is one of the main treatments for rectal cancer. In three-dimensional conformal radiotherapy, exposure of healthy tissue around the tumor is unavoidable. The small intestine is the most important organ at risk of rectal cancer radiotherapy. Intestinal complications are a major factor limiting the dose radiotherapy for rectal cancer. The most com...
