AIMS: Deep inspiration breath hold (DIBH) reduces cardiac radiation exposure by creating cardiac-chest wall separation in breast cancer radiotherapy. DIBH requires sustaining chest wall expansion for up to 40 s and involves complex co-ordination of thoraco-abdominal muscles, which may not be intuitive to patients. We investigated the effect of in-advance preparatory DIBH coaching and home practice on cardiac doses. MATERIALS AND METHODS: Successive patients from 1 February 2015 to 31 December 2016 with left-sided breast cancer who underwent tangential field radiotherapy utilising the DIBH technique were included...

RATIONALE: The typical symptoms of stress cardiomyopathy include sudden-onset chest pain and breathlessness or collapse as well as classical symptoms of cardiovascular disease; however, rare reports have described nervous system symptoms as the initial manifestation. Here, we report the case of a young man who presented with a large cerebral infarction as the main clinical symptom of stress cardiomyopathy to increase recognition of the disease. PATIENT CONCERNS: A 28-year-old man was admitted to our hospital for sudden-onset weakness of the right limbs and unconsciousness for 1 day...

On Earth, tissue weight generates compressive forces that press on body structures and act on the walls of vessels throughout the body. In microgravity tissues no longer have any weight and tissue compressive forces are lost, suggesting individuals who weigh more may show greater effects from microgravity exposure. One unique effect of long-duration microgravity exposure is the spaceflight-associated neuro-ocular syndrome (SANS) which can present with globe flattening, choroidal folds, optic disc edema, and a hyperopic visual shift...

Multiply injured patients with fractures are co-managed by acute care surgeons and orthopaedic surgeons. In most centers, orthopaedic surgeons definitively manage fractures, but preliminary management, including washouts, splinting, reductions, and external fixations, may be performed by selected acute care surgeons. The acute care surgeon should have a working knowledge of orthopaedic terminology to communicate with colleagues effectively. They should have an understanding of the composition of bone, periosteum, and cartilage, and their reaction when there is an injury...

Koji Kawaguchi, Kohei Yokoi
The standard therapy for patients with T3N0-1M0 non-small cell lung cancer (NSCLC) involving the chest wall is considered initial resection and adjuvant chemotherapy. However, the compliance of adjuvant therapy is relatively low, and the prognosis for those patients has not been satisfactory. We therefore advocated a new strategy of induction chemoradiotherapy followed by surgery and conducted a prospective, multi-institutional phaseⅡ trial with the aim of improving the survival. The mature results of this trial showed the treatment strategy to be safe and effective with a high rate of pathologic response...

We report a case of atrial septal defect (ASD) with severe pectus excavatum. A 50-year-old female had a stroke due to paradoxical embolism from deep vein thrombosis thorough ASD. Her preoperative computed tomography(CT) revealed a severe pectus excavatum (Haller CT index 28.6). The patient underwent ASD closure and repair of the pectus excavatum concomitantly. Median full sternotomy was performed for ASD closure. And we adopted sterno-costal elevation for pectus excavatum repair. Cartilages of the 3rd to the 7th rib were segmentally resected and the remainders were re-sutured to the sternum...

A 61-year-old woman was admitted to our hospital with progressive dyspnea on exertion. Chest X-rays and computed tomography (CT) showed elevation of the left diaphragm and atelectasis of the left lung. Eventration of the diaphragm was performed. The redundant diaphragm was plicated with vertical mattress sutures and reinforced by the suturing of the remnant diaphragm to the diaphragm near to the chest wall. During the thoracoscopic procedures, thoracoscopic examination from a small part of the resected diaphragm was conducted simultaneously to ensure safety and avoid damage to intra-abdominal organs...

Tubercular infection of the chest wall is rare and typically progresses to abscess formation. The treatment of these abscesses combines medical therapy with surgical debridement, which can cause defects of various sizes. We have reconstructed relatively small chest wall defects caused by tubercular abscesses using 2 different flaps: a lateral intercostal artery perforator flap and a split pectoralis major muscle flap. The use of these flap techniques may provide a novel approach to cover small chest wall defects caused by tubercular abscesses...

Parosteal lipoma derived from the rib is extremely rare and is usually resected through open thoracotomy despite its benign nature. A 33-year-old man who had no symptoms was referred to our hospital for treatment of a 30-mm chest wall mass that has slightly increased in size during 2 years of follow-up. En bloc resection of the tumor with parts of the 3rd and 4th ribs was performed through a complete thoracoscopic approach using orthopedic electric micro drill. This was the first report on a case of parosteal lipoma of the rib that was resected by a complete thoracoscopic procedure...

REVIEW
Jose Ribas Milanez de Campos, Thomas W White
Blunt trauma to the chest wall and rib fractures are remarkably frequent and are the basis of considerable morbidity and possible mortality. Surgical remedies for highly displaced rib fractures, especially in cases of flail chest, have been undertaken intermittently for more than 50 years. Rib-specific plating systems have started to be used in the last 10 years. These have ushered in the modern era of rib repair with chest wall stabilization (CWS) techniques that are safer, easier to perform, and more efficient...
