Chest Wall Reconstruction with Precontoured Locking Plate Proof of Concept  [PDF]
Elmer Lodder, Maarten van der Elst
Journal of Cancer Therapy (JCT) , 2010, DOI: 10.4236/jct.2010.13021
Abstract: Complications after chest wall resection are common and are reported to occur in approximately 40% of patients. The most frequent complications are respiratory or wound complications. Restoring rib continuity after a resection is likely to prevent respiratory complications. However many patients remain painful after a reconstruction. This article describes a new technique using a titanium alloy precontoured locking plate and locking screws to reconstruct the chest wall after resection of the 7th rib on the left.

Seydou Togo, Moussa Abdoulaye Ouattara, Ibrahim Boubacar Maiga, Yunping Lu, Donghui Jin, Ibrahim Sangaré, Maiga Abdoul Aziz, Cheik Amed Sekou Touré, Ibrahim Coulibaly, Jaques Saye, Cheik Sadibou, Sékou Koumaré, Sadio Yéna, Djibril Sangaré
Open Journal of Respiratory Diseases (OJRD) , 2016, DOI: 10.4236/ojrd.2016.61001
Abstract: Cavernous lymphangioma of the chest wall is a very rare disease entity, and only a few cases have ever been documented in the literature. Cases of recurrent cavernous lymphangioma after surgical excision of a cystic lymphangioma on the same side of the chest wall are quite uncommon. We report a case of a 10-year-old girl, with a giant cavernous lymphangioma of the left lateral chest wall extending into the axilla, who had undergone surgical excision of a cystic lymphangioma 9 years earlier.

Juan Carlos Trujillo-Reyes, Ramón Rami-Porta, Bienvenido Barreiro-López, Clarisa González-Mínguez, Lydia Canales Aliagad, Josep Belda-Sanchís
Open Journal of Thoracic Surgery (OJTS) , 2012, DOI: 10.4236/ojts.2012.22005
Abstract: A 53-year-old man with bleeding from a sternal mass associated with a toxic syndrome. Computed tomography (CT) revealed a destructive sternal mass, bilateral pleural effusion and an endobronchial lesion in the right middle lobe bronchus. Immunohistopathological study of an incisional biopsy confirmed metastasic lung adenocarcinoma.
Advances in the management of pectus deformities in children  [PDF]
Natalie Swergold, Prasanna Sridharan, Marios Loukas, Ronald S. Chamberlain
Open Journal of Pediatrics (OJPed) , 2013, DOI: 10.4236/ojped.2013.33038
Abstract:

Pectus excavatum (PE) and pectus carinatum (PC) are relatively common deformities involving the anterior chest wall, occurring in 1:1000 and 1:1500 live births, respectively. While the etiology remains an enigma, the association of pectus deformities with other skeletal abnormalities suggests that connective tissue disease may play a role in their pathogenesis. Clinical features of these deformities vary with severity, as determined by the Haller index and Backer ratio, but frequently include cardiac and respiratory abnormalities. Importantly, there exist profound psychosocial implications for children afflicted with these defofrmities, including but not limited to feelings of embarrassment and maladaptive social behaviors. These debilitating characteristics have prompted the development of novel medical and surgical corrective techniques. The correction of pectus deformities reduces the incidence of physiological complications secondary to chest wall malformation, while simultaneously improving body image and psychosocial development in the affected pediatric population. The Ravitch (open) and Nuss (minimally invasive) procedures remain the most frequently employed methods of pectus deformity repair, with no difference in overall complication rates, though individual complication rates vary with treatment. The Nuss procedure is associated with a higher rate of recurrence due to bar migration, hemothorax, and pneumothorax. Postoperative pain management is markedly more difficult in patients who have undergone Nuss repair. Patients undergoing the Ravitch procedure require less postoperative analgesia, but have longer operation times and a larger surgical scar. The cosmetic

results of the Nuss procedure and its minimally invasive nature make it preferable to the Ravitch repair. Newer treatment modalities, including the vacuum bell, magnetic mini-mover procedure (3MP), and dynamic compression bracing (DCB) appear promising, and may ultimately provide effective methods of noninvasive repair. However, these modalities suffer from a lack of extensive published evidence, and the limited number of studies currently published fail to adequately define their long-term effectiveness.

Experience with Porcine Acellular Dermal Collagen Mesh (Permacol™ Surgical Implant) in Chest Wall Reconstruction after Resection for Rib Osteomyelitis  [PDF]
Claudia Hannele Mazzetti, Patrick Carlier, Alexis Therasse, Jean Lemaitre
Open Journal of Thoracic Surgery (OJTS) , 2015, DOI: 10.4236/ojts.2015.52006
Abstract: Chest wall reconstruction after rib resection is essential to ensuring chest wall stability, avoiding flail chest and pulmonary hernia, and improving pulmonary function. Traditionally, a synthetic mesh and a musculocutaneous flap have been used to bridge the chest wall defect. However, a risk of secondary prosthesis infection exists. Acellular dermal collagen mesh implants (Permacol) are indicated for the reconstruction and reformation of human soft connective tissue. A case of a complex chest wall reconstruction after rib resection for osteomyelitis due to staphylococcus aureus infection in a malnourished, immunosuppressed, and methadone-addicted patient is presented. The patient underwent a left posterolateral thoracotomy and chest wall resection, involving three ribs and the soft tissues overlying an infected cutaneous fistula. The chest wall was reconstructed using a 28 × 18 cm piece of porcine sterile acellular dermal collagen mesh. A successful chest wall repair was achieved with no incisional herniation and with complete mesh incorporation, allowing physiologic respiratory movements. A typical wound seroma developed and resorbed over the following months. There was no infection. In conclusion, this case report suggests that Permacol surgical implant can be used successfully as an alternative to synthetic mesh in reconstruction of an infected chest wall.

Titanium Rib Plate Technique for Huge Chest Wall Reconstruction  [PDF]
Yong Han Yoon
Surgical Science (SS) , 2011, DOI: 10.4236/ss.2011.26070
Abstract: Chest wall reconstruction after en-bloc tumor resection is very important to preserve functional mobility and to enhance the cosmetic effect. Because they are flexible and pliable, titanium plates are proposed to reconstruct the chest wall, even though such chest wall reconstruction has been performed in only a few cases worldwide. We present a case of a 49-year-old man with a chondrosarcoma arising from the left 1st rib, invading the manubrium, clavicle, 2nd and 3rd ribs, and the anterior segment of the left upper lobe. After wide resection, the chest wall was reconstructed using titanium rib plates and Marlex mesh- the Bovine pericardium sandwich type. The patient tolerated the pain well, and fourteen months after surgery, the chest wall was well preserved function mobility and improved pulmonary function test.

Rudra Kanta Deka, Sankar Kumar Das
Engineering (ENG) , 2011, DOI: 10.4236/eng.2011.312149
Abstract: The effect of radiation on the unsteady natural convection flow past an infinite vertical plate is presented, wherein the plate temperature is a ramped one. The fluid considered here is a gray, absorbing/emitting but a non-scattering medium. The influence of the various parameters entering into the problem on the velocity field, temperature field, skin friction and Nusselt number is studied.

Mukesh Sangwan, Vijayata Sangwan, Mahender Garg, Parveen Mahendirutta, Uma Garg
Open Journal of Epidemiology (OJEpi) , 2013, DOI: 10.4236/ojepi.2013.33020
Abstract:

Hernia is a common word that most surgeons are familiar with. A retrospective study was planned to analyse the spectrum of abdominal wall hernias in a rural population inIndia. Majority of the patients were of 40 - 70 yrs. Male to female ratio was 7:1. Incidence of groin hernias showed an increasing trend with advancing age. Out of total 320 cases, inguinal hernias were predominating in 77.81% cases. Ventral hernias were present in about 18% cases. However, femoral hernias were rare. We concluded that spectrum of abdominal wall hernias is almost the same all over the globe despite having differences in their socioeconomic and educational status.

Chaos Appearance during Domain Wall Motion under Electronic Transfer in Nanomagnets  [PDF]
Donfack Gildas Hermann, Jean-Pierre Nguenang
World Journal of Condensed Matter Physics (WJCMP) , 2013, DOI: 10.4236/wjcmp.2013.33022
Abstract:

In this paper, we study the likelihood of chaos appearance during domain wall motion induced by electronic transfer. Considering a time-varying current density theory, we proceed to a numerical investigation of the dynamics. Using the dissipation parameter, amplitude and frequency of current density as control parameters; we show how periodic regime as well as chaotic regime can be exhibited in nanomagnetic systems. Numerical results allow setting up the periodicity and quasi-periodicity of system and chaotic phenomena occurring during magnetization switching process in nanomagnet through electronic transfer.
