multiwall carbon nanotubes (mwcnts) are grown via chemical vapour deposition method directly on a stainless steel substrate. raman spectroscopy and transmission electron microscopy are the techniques chosen to characterize the structure of the synthesized carbon nanotubes: few structural defects are detected. after their removal from the stainless steel substrate, the as-grown mwcnts are then a...

Background. Laparoscopic adjustable gastric banding (LAGB) is a popular method for the treatment of morbid obesity. One of the most feared complications is gastric band erosion which occurs with a reported incidence of 0.3 to 14%. Intragastric migrated bands are best managed by endoscopic removal. Recent case studies reported successful endoscopic removal of intragastric migrated bands, but it ...

Uterine wall perforation which is commonly seen through the posterior wall of the uterus is the most serious complication of an intrauterine device (IUD). We present a case of laparoscopic removal of an IUD from the sigmoid colon in a 31-years-old female who was admitted to hospital with a history of pelvic pain and abnormal vaginal bleeding for one month. The dislocated IUD was removed from th...

BACKGROUND The World Health Organisation and the Joint United Nations Programme on HIV/AIDS have recommended the scale-up of Medical Male Circumcision (MMC) in countries with high HIV and low MMC prevalence. PrePex device circumcision is proposed as an alternate method for scaling up MMC. OBJECTIVE Evaluate safety and feasibility of PrePex in South Africa. DESIGN A multisite prospective coh...

Intrauterine devices (IUDs) remain highly effective reversible family planning methods in developing countries. We aimed to report one of the complications of extrauterine and intrauterine devices. A 44-year-old woman was admitted to our hospital with mislocated intrauterine device and abnormal uterine bleeding. Extrauterine IUD device was proven by ultrasound and X-ray. She had normal blood te...

A microcatheter foreign body retrieval device is described and its first two clinical applications are presented. The device functions identically to larger loop snare retrievers. It permits access to small vessels and was successful in its first clinical applications.

The intra-uterine device (Copper T) has been widely used as contraceptive method since 1965. Due to its low cost, effective and reversible nature and long-term benefits, it is widely being used in the developing world. The intra-uterine contraceptive device (IUCD) has been linked to complications like bleeding, perforation and migration to other surrounding organs. The intra-abdomen migration o...

OBJECTIVE Discectomy as a treatment for herniated lumbar discs results in outcomes after surgery that are not uniformly positive. Surgeons face the dilemma between limited nucleus removal which is associated with a higher risk of recurrence, or more aggressive nucleus removal which may lead to disc height loss and persistent back-pain. annulus closure devices may allow for the benefits of limit...
