Treatment of the Breast’s Lateral Pole: Adjuvant Maneuver to Pitanguy’s Technique

Surgical procedures for the mammary region currently are assuming an important role in body-contouring surgery. Enhancement of results is a constant challenge to the plastic surgeon. A simple and efficient maneuver for resection of the breast’s lateral pole based on the mammoplasty technique of Professor Ivo Pitanguy is described. This study realized at the Private Clinic Sérgio Carreir?o, Rio de Janeiro, RJ, Brazil.     

Parental Communication Not to Smoke and Adolescent Cigarette Smokers' Readiness to Quit: Differences by Age

There is limited information on the relationship between parental practices that specifically discourage current cigarette smoking and adolescent cessation, and how this relationship varies by age. Among 1629 adolescent smokers, self-reported receipt of parental communication not to smoke was significantly and positively associated with readiness to quit. The strength and significance of this association decreased from early to middle adolescence and was not significant in late adolescence.     

Laparoscopic Medial-to-lateral Colon Dissection: How and Why

Laparoscopic colectomy is a difficult procedure with a long learning curve. We describe in this study our technique for right- and left-sided laparoscopic medial-to-lateral colectomy. The medial approach involves division of the vascular pedicle first, followed by mobilization of the mesentery toward the abdominal wall, and finally freeing of the colon along the white line of Toldt. This approach allows immediate identification of the plane between the mesocolon and the retroperitoneum and renders the dissection fast and safe. Our series of 50 consecutive laparoscopic colectomies supports this concept. We believe that surgeons familiar with this technique will have an important tool in their armamentarium to circumvent some of the challenges of laparoscopic colectomy.     

Short term correlates of the Neuro Emotional Technique for cancer-related traumatic stress symptoms: A pilot case series

Introduction As many as one quarter of all cancer survivors report traumatic stress symptoms from cancer-related experiences. While the majority of these patients do not meet the criteria for posttraumatic stress disorder (PTSD), there is growing evidence that subsyndromal symptoms can significantly contribute to functional impairment and negative health outcomes. Treatment options for the hallmark symptoms of traumatic stress—unpleasant, intrusive thoughts and avoidant behaviors—have not been well investigated for the cancer survivorship population. Materials and methods Seven female cancer survivors with traumatic stress symptoms from cancer-related experiences and no other major psychopathology, were enrolled to receive three sessions of Neuro-Emotional Technique (NET), a brief, targeted treatment that combines traditional desensitization principles with complementary modalities. Results Psychological outcome measures (Impact of Event Scale (IES) and Subjective Units of Distress (SUD) and physiological measures (Heart Rate (HR) and Skin Conductance Level (SCL) demonstrated the following changes: 71% on IES, 88% SUD, 74% on HR, and 65% on SCL following the intervention. Statistically significant changes were observed for all four parameters, and effect size g for proportion improved were 0.50 each for IES, SUD, and HR, and 0.20 for SCL. Conclusions These cases suggest feasibility of the NET intervention for cancer-related traumatic stress and the potential for change in symptoms and physiological reactivity. Further investigation is needed to determine the specific and long-term effects of such an approach. Implications for cancer survivors Traumatic stress from cancer-related experiences might represent a constellation of symptoms that are amenable to brief, targeted interventions.

急性缺氧对大鼠海马神经元钙激活钾通道的作用

目的:本实验采用膜片钳单通道技术研究缺氧条件下对培养新生大鼠海马神经元钙激活钾通道的作用;方法:取1 ～3天的SD大鼠海马神经元组织,制成细胞悬液,加入含80 %DMEM(dulbecco' s modified eagle' s medium)、20 %小牛血清培养基进行培养,将培养3 ～5天的形态典型的神经元置于对称性高钾溶液中,用膜钳技术记录单通道电流,其通道电流通过膜片钳放大器(CEZ -2200)放大,滤波(3KHz)后,经A/D、D/A转换器输入计算机,采用pClamp6 .0 .6软件采样分析;结果:在细胞贴附式下,应用氰化钠(20μmol/L)造成细胞急性缺氧,在缺氧早期(5 ～20 min)通道开放概率增加(P<0 .01或P<0 .05 ,n=5) ,而缺氧后期(20 ～30 min) ,通道开放概率明显降低,表明缺氧时间对通道的开放概率有明显影响。结论:缺氧早期神经元钙激活钾通道有自身激活作用,当钙激活钾通道激活时,钾离子外流增加,产生膜的复极化,使去极化不易产生,从而稳定细胞膜及降低细胞的兴奋性,这可能是缺氧早期神经元自身的一种代偿机制。

An Improved Method of Removing Polyurethane Foam-Covered Gel Prostheses

One of the advantages of polyurethane foam-covered prostheses has been that in the first 5 to 10 years after their use, the amount of capsular contraction was found much less than when similar ``slick' prostheses were used. Another advance was their fixation to the surrounding tissue thus giving a more natural appearance and movement with the muscles when the arms were moved in any direction. The formation of a thick capsule also acted as a protection against gel granuloma due to rupture of the prosthesis and has been thought to be a factor in the lower capsule contraction rate. The greatest disadvantage has been that its removal was extremely difficult and this has continued up until the technique described in this paper has been introduced.     

The synchronization of respiration and swallow sounds with videofluoroscopy during swallowing

Simultaneous recording of adult subjects sipping small amounts of fluid from a cup have been obtained by videofluoroscopy together with feeding respiratory patterns and swallow sounds from the Exeter Dysphagia Assessment Technique (EDAT). These allowed visual representations of respiration and swallow sounds to be superimposed on a videofluoroscopy recording using a split-screen technique. Sequentially numbered, 1/50 sec, half-frame photographic prints were examined and schematic drawings of the relevant radiographs were made. These were superimposed on to the actual EDAT printed chart of the same swallow event, theri exact time relationship with respiration and cervical swallow sounds being preserved. The results allow events in the barium videofluoroscopy to be related to events in the feeding respiratory pattern and swallow sounds recorded by EDAT.     

A simple technique for thoracoscopic resection of lung tumors

Mainly incited by the bushfirelike spread of endoscopic operative techniques in general surgery, thoracoscopy has become the object of new interest in the field of thoracic surgery. Location and resection of lung tumors are problematic for several reasons and so far not standardized. The main problems are pointed out. A new technique together with the instruments and their advantages is demonstrated. Future aspects are discussed.     

Benefits of the DICOM Structured Report

Recently, the digital imaging and communications in medicine (DICOM) standard introduced rules for the encoding, transmission, and storage of the imaging diagnostic report. This medical document can be stored and communicated with the images in picture archiving and communication system (PACS). It is a structured document that contains text with links to other data such as images, waveforms, and spatial or temporal coordinates. Its structure, along with its wide use of coded information, enables the semantic understanding of the data that is essential for the Electronic Healthcare Record deployment. In this article, we present DICOM Structured Report (SR) and discuss its benefits. We show how SR enables efficient radiology workflow, improves patient care, optimizes reimbursement, and enhances the radiology ergonomic working conditions. As structured input significantly alters the interpretation process, understanding all its benefits is necessary to support the change.
