Zebra finches have been widely used to study neurobiology underlying vocal development. Because only male zebra finches learn song, efficient developmental use of these animals requires early determination of sex at ages that precede maturation of secondary sex characteristics. We have developed a sex determination method that combines a forensics method of genomic DNA isolation (from very smal...

Sialolithiasis is the presence of stones in the ducts of the salivary glands. Most episodes are unique, and 60-80% are located exclusively in the main excretory duct. The main clinical manifestations are swelling and pain typically before, during or after meals that decreases if the obstruction is not complete. The highest prevalence of lithiasis is in the submandibular gland -87%-, whose secre...

BACKGROUND Minimally invasive pancreaticoduodenectomy (MIPD) remains one of the most challenging abdominal procedures. Safety and feasibility remain controversial when comparing MIPD with open pancreaticoduodenectomy (OPD). The aim of this systematic review and meta-analysis was to evaluate the feasibility and safety of MIPD versus OPD. METHODS A systematic review of the literature was perfor...

The complex thoracic deformity has both protrusion and depression on the chest wall, its appearance is complex. It difficult to complete correction by ordinary surgical methods. In early years, this kind of needed be treated open surgery. After entering era minimally invasive surgery, operation also gradually invasive, it can completed through combination different operations. Mild deformities ...

Pancreatic pseudocysts in children are not uncommon. Non-resolving pseudocysts often require surgical intervention. Endoscopic cystogastrostomy is a minimally invasive procedure which is recommended for this condition. We report a large pancreatic pseudocyst in a 4-year old child, which developed following therapy with PEG-Asparaginase for acute lymphoblastic leukemia. It was managed with minim...

The recent development of radioguided parathyroidectomy has allowed parathyroidectomy to be quickly performed by a significantly less invasive procedure. Radioguided parathyroidectomy is also likely to decrease operation time, risk of complications, hospital stay, and the overall cost of patient care, result in a smaller scar and rapid, nearly pain-free recovery, and allow local anesthesia. Des...

In clinical trials examining the incidence of pneumonia it is a common practice to measure infection via both invasive and non-invasive procedures. In the context of a recently completed randomized trial comparing two treatments the invasive procedure was only utilized in certain scenarios due to the added risk involved, and given that the level of the non-invasive procedure surpassed a given t...

background the phrase “minimally invasive” is used loosely due to the wide range of surgical options and generally means a procedure not involving a large open incision. in 1998, dr. paolo miccoli at the university of pisa developed a technique of minimally invasive video-assisted thyroidectomy (mivat) for patients presenting with small thyroid nodules. the procedure involves a smaller incision...

Pectus excavatum is the most common congenital deformity of the chest wall. The most frequently used techniques include Ravitch (costochondral resection) and Nuss (minimally invasive pectus repair of pectus excavatum [MIRPE]). The Nuss technique includes using temporary metallic bars without costochondral resection to correct the chest wall deformity. Modified MIRPE can be learned easily and pe...

   As an invasive procedure endoscopic retrograde cholangiopancreatography is prone to develop complications including; pancreatitis, bleeding, cholangitis, and perforation. There are also other complications like pneumothorax, which are so rare. Although this complication is rare, delay in its management may lead to lethal consequences. The present study report a case of post- ERCP pneumothora...
