BACKGROUND: We report a case of a complex chest wall reconstruction because of sternal dehiscence, requiring different surgical procedures for its complete resolution. CASE REPORT: A 54-year-old man patient with Langerhans cell histiocytosis and chronic obstructive pulmonary disease underwent bilateral sequential lung transplantation through a clamshell incision, using nitinol thermo-reactive clips for sternal closure. One year later, he consulted because of chest pain, fever, and purulent secretions...

INTRODUCTION: The prevalence of life-threatening complications (LTCs) related to the minimally invasive repair of pectus excavatum (MIRPE) is unknown and underreported. The aim of this study is to contribute to the real prevalence of these rare but dramatic complications and show what went wrong in order to prevent it in the future. CASE PRESENTATION: A 15-year-old boy affected by pectus excavatum with severe asymmetric deformity of the chest wall was evaluated for elective corrective surgery...

INTRODUCTION AND IMPORTANCE: Primary pericardial tumors are very rare with an overall incidence of 0.001-0.007 % and account for approximately 10 % of heart neoplasms. We present two clinical cases of massive mature intrapericardial lipomas (maximum size 270 × 230 mm) that were successfully treated in our department. CASE PRESENTATION: The first case is that of a 67-year-old male patient who underwent diagnostic investigations after the onset of dyspnea, which confirmed an intrapericardial mass of 270 × 230 mm in size that extended into the left lung field and was treated surgically by a clamshell incision...

Nowadays, different systems for reducing pesticides in table grapes are being tested at different production stages either in the field or in postharvest. The present study tested ozonated water treatments at the beginning of the cold storage of the Princess® seedless table grape variety to reduce the residue contents of some pesticides and to evaluate their effect on gray mold and the berry microbiome. An ozone generator capable of producing an ozone concentration ranging from 18 to 65 Nm3 was utilized for obtaining three ozone concentration levels in water: 3, 5 and 10 mg/L...

Ganglioneuroma is a benign tumor requiring subtotal resection as a primary mode of treatment. There are several surgical approaches. A giant ganglioneuroma of the chest cavity may be approached via a clamshell thoracotomy. This manuscript presents a case of giant ganglioneuroma resected en bloc via clamshell thoracotomy in a seven-year-old child.

Augmentation cystoplasty (AC) is a well-established surgical option for the management of overactive bladder where conservative management has failed. We describe the case of a man in his 50s with chronic bladder dysfunction secondary to refractory detrusor overactivity and small capacity bladder. His lower urinary tract symptoms (LUTS) of urinary frequency and nocturia persisted despite pharmacological therapy and peripheral neural modulation; hence, he underwent surgical intervention for management of his bladder dysfunction...

CASE: Here, we describe a case of a 49-year-old female patient with a history of hypertension and polysubstance use disorder presenting with a distal tibial metaphyseal malunion treated with a clamshell osteotomy. Her follow-up was 2.5 years long. CONCLUSION: Malunions in the tibial diaphysis and distal metaphysis can cause significantly increased joint reaction forces and altered gait mechanics leading to cosmetic dissatisfaction and decreased quality of life for these patients...

BACKGROUND: Coccydynia is a challenging disorder that is frequently managed conservatively. OBJECTIVE: This study aimed to evaluate the efficacy of adding kinesiotaping versus pelvic floor exercise to conventional therapy in the management of post-colonoscopy coccydynia. METHODS: Forty-two participants, aged 25-45 years, were randomly assigned to: the conventional therapy group (CT) receiving Piriformis and Iliopsoas muscle stretching exercise, clamshell exercise, and seat cushioning; the CT plus kinesiotaping group (CT-KT) receiving additional kinesiotaping; or the CT plus pelvic floor exercise (PFE) group (CT-PFE) executing additional PFE...

This study focuses on the modification of natural hydroxyapatite (HAp) derived from clamshell by impregnation with palladium (Pd) at different pH in wet precipitation method to produce photoactive green materials for the degradation of synthetic dyes. It was found that, at pH 10, Pd has been successfully impregnated into HAp lattice with Ca/P ratio of 1.77 and particle distribution size range of 40-470 nm. The impregnation has resulted in the band gap of Pd/HAp at 3.19 eV, as calculated using Tauc's plot from the UV-Vis spectroscopy data of the Pd/HAp...

BACKGROUND: Wrist pain in the extended or extended weightbearing positions may be incompletely evaluated using standard magnetic resonance imaging (MRI) with standard rigid clamshell coils in the neutral position. PURPOSE: To evaluate a flexible 24-channel glove coil and harness when imaging the wrist in neutral, dorsally extended, and weightbearing positions. MATERIAL AND METHODS: Ten wrists in 10 asymptomatic volunteers (mean age = 29 years) were scanned...

BACKGROUND: Minimally invasive mitral valve surgery (MIV) through a right lateral thoracotomy has become the standard of care at specialized centers and might soon will be the only acceptable surgical treatment option in the future era of interventional procedures. The aim of our study was to analyze the outcomes of our MIV-specialized, single-center, mixed valve pathology cohort with regard to morbidity, mortality and midterm outcomes comparing two different repair techniques (respect versus resect)...

PURPOSE: Resuscitative thoracotomies (RT) are the last resort to reduce mortality in patients suffering severe trauma. In recent years, indications for RT have been extended from penetrating to blunt trauma. However, discussions on efficacy are still ongoing, as data on this rarely performed procedure are often scarce. Therefore, this study analyzed RT approaches, intraoperative findings, and clinical outcome measures following RT in patients with cardiac arrest following blunt trauma...

Droplet actuation on wires or fibers is highly relevant to digital microfluidics applications. Several different passive or active actuation mechanisms have been studied, including capillary pressure, thermal gradient, tilting, acoustics, and electrowetting, to name a few. However, the lack of precise control and accurate droplet positioning during its actuation on a wire limits the use of earlier methods. On the other hand, using a nonuniform magnetic field to actuate a droplet on a micrometer-size wire helps overcome the above limitations...

Historically it was recommended for emergency thoracotomy in thoracic trauma as the last resort when there was cardiopulmonary arrest. Nowadays, the only indications are lung transplantation and huge mediastinal masses. We report the use of a clamshell thoracotomy in a 7-month-old boy with a large anterior mediastinal mass extending into the bilateral thoracic cavities.

Lab-on-a-chip technologies and microfluidics have pushed miniaturized liquid handling to unprecedented precision, integration, and automation, which improved the reaction efficiency of immunoassays. However, most microfluidic immunoassay systems still require bulky infrastructures, such as external pressure sources, pneumatic systems, and complex manual tubing and interface connections. Such requirements prevent plug-and-play operation at the point-of-care (POC) settings. Here we present a fully automated handheld general microfluidic liquid handling automation platform with a plug-and-play 'clamshell-style' cartridge socket, a miniature electro-pneumatic controller, and injection-moldable plastic cartridges...

The aim of this study was to assess the safety and clinical outcome of patients with a femoral shaft fracture and a previous complex post-traumatic femoral malunion who were treated with a clamshell osteotomy and fixation with an intramedullary nail (IMN). The study involved a retrospective analysis of 23 patients. All had a previous, operatively managed, femoral shaft fracture with malunion due to hardware failure. They were treated with a clamshell osteotomy between May 2015 and March 2020. The mean age was 42...

Solitary fibrous tumors (SFTs) are rare mesenchymal pleural neoplasms with an overall good prognosis and low recurrence rate if completely resected and if degree of differentiation is favorable. Within the last decade, advances in research have led to more reliable methods of differentiating SFTs from other soft tissue tumors. Historically, several markers were used to distinguish SFTs from similar tumors, but these markers had poor specificity. Recent evidence showed NAB2-STAT6 fusion gene to be a distinct feature of SFTs with 100% specificity and sensitivity...

INTRODUCTION: Fractures of the polyethylene post are a rare but known complication after posterior-stabilized (PS) total knee arthroplasty (TKA). We evaluated the polyethylene and patient characteristics for 33 primary PS polyethylene components that were revised with fractured posts. METHODS: We identified 33 PS inserts revised between 2015 and 2022. Patient characteristics collected included age at index TKA, sex, body mass index (BMI), length of implantation (LOI), and patient reported details on events surrounding the post fracture...

Mature fetiform teratoma, or homunculus, is a term coined for a rare variant of teratoma with a prevalence of 0.01% of teratomas. There have been very few cases reported in the world, and its thoracic presentation is extremely unusual. We present the case of a 31-year-old female patient with a history of progressive chest pain in the left hemithorax, associated with dyspnea on moderate exertion and cough. Imaging studies revealed a large intrathoracic tumor visually compatible with a teratoma. Surgical resection by a clamshell approach was successful, and subsequent anatomopathological studies of the operative specimen concluded that the mass was a mature fetiform thoracic teratoma...

Recycling of stalled, translationally inactive ribosomes is one of the response mechanisms underlying resistance to environmental stress. HflX, a bacterial GTPase overexpressed upon heat shock and exposure to antibiotics, catalyzes the splitting of stalled ribosomes 1-6 . Due to its rapid rate, an attempt to follow this process in real time at room temperature requires time-resolved techniques on the scale of tens of milliseconds 1 . Here we show the time course of the splitting of E. coli 70S ribosome by HflX in the presence of GTP using time-resolved cryo-EM with a microfluidic device...
