OBJECTIVE: To assess the feasibility and safety of a novel flexible mini-nephroscope in minimally-invasive PCNL. Presumably, limiting the size and number of tracts during percutaneous-nephrolithotomy(PCNL) has the potential of decreasing the morbidity of the procedure. We present our experience with, this new technique. METHODS: A retrospective analysis of patients with multiple kidney stones treated with mini-PCNL combined with a novel flexible mini-nephroscope was performed...

Positron emission tomography (PET) scanners designed for imaging of small animals have transformed translational research by reducing the necessity to invasively monitor physiology and disease progression. Virtually all of these scanners are based on the use of pixelated detector modules arranged in rings. This design, while generally successful, has some limitations. Specifically, use of discrete detector modules to construct PET scanners reduces detection sensitivity and can introduce artifacts in reconstructed images, requiring the use of correction methods...

Brachymetatarsia is a rare disease defined by metatarsal shortening and characterized by aesthetic dissatisfaction with or without pain. The aim of our study was to evaluate the outcomes of fourth ray brachymetatarsia treated with percutaneous osteotomy using a mini-burr and gradual lengthening with external fixation. A total of 7 females were recruited for the study; 6 (85.71%) of whom had a bilateral deformity, for a total of 13 feet affected by fourth ray brachymetatarsia. Percutaneous diaphysis osteotomy with a mini-burr followed by metatarsal elongation was performed...

Background Femoroacetabular impingement (FAI) describes a painful, abnormal (bony) contact between the femoral neck and acetabulum, which, if left untreated, contributes to early osteoarthritis (OA) of the hip. Despite its flat learning curve and long operation times, hip arthroscopy has been used increasingly often in recent years in the surgery of femoroacetabular impingement. The mini-open technique (MOT) offers a possible alternative that addresses the abnormal morphological prominence and allows minimally invasive clearance of hip motion...

Layering a regenerative polymer scaffold on the surface of the heart, termed as a cardiac patch, has been proven to be effective in preserving cardiac function after myocardial infarction. However, the placement of such a patch on the heart usually needs open-chest surgery, which is traumatic therefore prevents the translation of this strategy into the clinic. We sought to device a novel method to apply a cardiac patch by spray painting in situ polymerizable biomaterials onto the heart with a minimally invasive procedure...

OBJECTIVE Advanced age is known to be associated with a poor prognosis after surgical clipping of unruptured intracranial aneurysms (UIAs). Keyhole clipping techniques have been introduced for less invasive treatment of UIAs. In this study, the authors compared the complications and clinical and radiological outcomes after keyhole clipping between nonfrail elderly patients (≥ 70 years) and nonelderly patients. METHODS Keyhole clipping (either supraorbital or pterional) was performed to treat 260 cases of relatively small (≤ 10 mm) anterior circulation UIAs...

BACKGROUND: The impact of postoperative complications (POCs) on long-term outcomes following hepatocellular carcinoma (HCC) resection remains to be ascertained. METHODS: All consecutive HCC resected at a single center were analyzed. Patients with POCs, classified according to Clavien classification, were compared to those without in terms of demographics, pathology, management, overall survival (OS), and disease-free survival (DFS). Independent prognostic factors of POCs were identified using multivariable regression models...

Minimally invasive resections are increasingly employed in oncologic surgery for esophageal carcinoma. The new German S3 guideline states that esophagectomy, as well as reconstruction of the esophagus, can be performed minimally invasively or in combination with open techniques (hybrid). However, the current value of different techniques - ranging from complete minimally invasive esophagectomy over hybrid to robotic surgery - remains unregarded.This review provides a critical comparison of these techniques based on current evidence...

If your young patient doesn't feel comfortable and thinks something dreadful is going to happen when he comes to your office, maybe he will develop dental fear. Nowadays, children and teenagers' strong negative emotions related to dental treatment are defined as "Dental Fear and Anxiety" (DFA). Since DFA can result in children's avoidance or delay in undergoing dental visits, this problem represents a relevant social barrier as important as other well-known factors like low family income or parental education...

The gold standard to arrange impacted teeth in the dental arch is represented by a surgical approach followed by orthodontic traction force application. In the literature, many surgical approaches are proposed to reach such a scope. The aim of the present study is to demonstrate how laser technique could positively assist surgical approaches.Study population was composed by 16 patients undergoing orthodontic treatment of 20 impacted teeth. In 10 patients (population A) surgical exposure of the impacted teeth was performed using a 980 nm diode laser, while in the other 10 patients (population B), surgical incision was performed using a traditional lancet...

The mammalian Mcm-domain containing 2 (Mcmdc2) gene encodes a protein of unknown function that is homologous to the mini-chromosome maintenance family of DNA replication licensing and helicase factors. Drosophila melanogaster contains two separate genes, the "Mei-MCMs," that appear to have arisen from a single ancestral Mcmdc2 gene. The Mei-MCMs are involved in promoting meiotic crossovers by blocking the anti-crossover activity of BLM helicase, a function presumably performed by MSH4 and MSH5 in metazoans...

Introduction. In the last years many mini-invasive approaches were developed in order to reduce postoperative pain and complication after haemorrhoid surgery: one of these alternatives is represented by Hemorpex System, a relatively young technique that combines transanal dearterialization with mucopexy through a dedicated proctoscope. Case Presentation. A 78-year-old male patient was admitted to the Emergency Department for acute urinary retention and elevated temperature. Hemorpex procedure was performed 4 years before...

Tubulin is the target for very widely used anti-tumor drugs, including Vinca alkaloids, taxanes, and epothilones, which are an important component of chemotherapy in breast cancer and other malignancies. Paclitaxel and other tubulin-targeting drugs bind to the β subunit of tubulin, which is a heterodimer of α and β subunits. β-Tubulin exists in the form of multiple isotypes, which are differentially expressed in normal and neoplastic cells and differ in their ability to bind to drugs. Among them, the βIII isotype is overexpressed in many aggressive and metastatic cancers and may serve as a prognostic marker in certain types of cancer...

The rare, long-lived radiotracer, (41)Ca, measured by accelerator mass spectrometry in the urine or serum following incorporation into the bone provides an ultra-sensitive tool to assess changes in bone calcium balance in response to an intervention. Changes in bone balance can be followed for years with one small dose that is both radiologically and biologically non-invasive. Sequential interventions can be compared, with greater precision than they can with biochemical markers of bone turnover and with greater power than with bone densitometry...

We report a novel less-invasive extrapleural pneumonectomy for early-stage malignant pleural mesothelioma without rib spreading. Our approach is unique and differed from the previously reported cases, because we used one skin incision and two small intercostal incisions with videothoracoscopic viewing without rib spreading. The pleural dissection and approach to the hilum for pneumonectomy were performed through a 4- to 5-cm port incision in the sixth intercostal space. Another 4- to 5-cm port was made in the eight intercostal space through the same skin incision and was used for diaphragm resection and reconstruction...
