Lumbar hernias can be superior (Grynfelt) and inferior (Petit). Inferior lumbar hernias are extremely rare and, therefore, are associated with diagnostic difficulty. We present a case of a primary spontaneous inferior lumbar hernia in a 79-year-old woman that was initially diagnosed as a large lipoma on ultrasound. The first operation was abandoned and an open mesh repair was conducted. Lumbar hernias can be primary acquired (55%), secondary acquired (25%) or congenital (20%). Cross-sectional imaging by CT or MRI appears to be the gold standard in diagnosis as ultrasound may lead to misdiagnosis...

REVIEW
Huijing Xiang, Yu Chen
Serious side effects to surrounding normal tissues and unsatisfactory therapeutic efficacy hamper the further clinic applications of conventional cancer-therapeutic strategies, such as chemotherapy and surgery. The fast development of nanotechnology provides unprecedented superiorities for cancer therapeutics. Externally activatable therapeutic modalities mediated by nanomaterials, relying on highly effective energy transformation to release therapeutic elements/effects (cytotoxic reactive oxygen species, thermal effect, photoelectric effect, Compton effect, cavitation effect, mechanical effect or chemotherapeutic drug) for cancer therapies, categorized and termed as "energy-converting nanomedicine," have arouse considerable concern due to their noninvasiveness, desirable tissue-penetration depth, and accurate modulation of therapeutic dose...

BACKGROUND AND OBJECTIVES: Percutaneous peripheral nerve stimulation (PNS) is an analgesic modality involving the insertion of a lead through an introducing needle followed by the delivery of electric current. This modality has been reported to treat chronic pain as well as postoperative pain following knee and foot surgery. However, it remains unknown if this analgesic technique may be used in ambulatory patients following upper extremity surgery. The purpose of this proof-of-concept study was to investigate various lead implantation locations and evaluate the feasibility of using percutaneous brachial plexus PNS to treat surgical pain following ambulatory rotator cuff repair in the immediate postoperative period...

Characterization of the main tibiofemoral ligaments is an essential step in developing patient-specific computational models of the knee joint for personalized surgery pre-planning. Tensile tests are commonly performed in-vitro to characterize the mechanical stiffness and rupture force of the knee ligaments which makes the technique unsuitable for in-vivo application. The time required for the limited noninvasive approaches for properties estimation based on knee laxity remained the main obstacle in clinical implementation...

Endoscopic ultrasound (EUS)-guided transgastric drainage has been performed as a less invasive procedure for pancreatic fistulas and intra-abdominal abscesses occurring after surgery in recent years. However, there are no reports of EUS-guided transgastric drainage of intra-abdominal abscesses following gastrectomy. This case report describes 2 patients who developed an intra-abdominal abscess following gastrectomy and underwent EUS-guided transgastric drainage. Both patients underwent laparoscopy-assisted distal gastrectomy with Billroth-I reconstruction for gastric cancer...

We present a case of successfully treated abdominal aortic aneurysm in a 24-year old patient with Marfan's syndrome. Following initial physical and ultrasound examination, the multislice computed tomography scan revealed infrarenal aortic aneurysm of 6 cm in diameter, 10 cm long, along with slightly dilated iliac arteries. However, dimensions of aortic root, aortic arch and descending suprarenal aorta were within normal limits. Further on, since the patient presented with signs of impending rupture, an urgent surgical intervention was performed...

A 49-year-old woman presented with a multinodular goiter, causing local symptoms and hyperthyroisdism. Besides a hypofunctioning benign nodule (TIRADS 3, benign in FNAC), the conventional diagnostic revealed another small hyperfunctioning nodule with suspicious ultrasound features (TIRADS 4C). To rule out a trapping-only nodule and topographical misalignments, a I PET/ultrasound fusion was performed and confirmed elevated iodine uptake within the suspicious nodule. Further disseminated autonomous areas are suspected to be additionally responsible for the low TSH-level...
