Combined quadriceps tendon reconstruction and total knee replacement with computer navigation: a case report.

Background: Chronic quadriceps tendon rupture is technically challenging for surgeons due to scarring and tendon retraction. The presence of concurrent ipsilateral knee osteoarthritis compounds the issue even further. Although a combined presentation is rare, treatment options to manage each coexisting pathology simultaneously are scarcely reported.

The surgical waiting time initiative: A review of the Nigerian situation.

The concept of surgical waiting time initiative (SWAT) was introduced in developed countries to reduce elective surgery waiting lists and increase efficiency of care. It was supplemented by increasing popularity of day surgery, which shortens elective waiting lists and minimises cancellations. It is established in Western countries, but not in developing countries like Nigeria where it is still evolving.

Biomedical techniques in translational studies: The journey so far.

Biomedical techniques have wide clinical application in many fields of medicine such as oncology, rheumatology, immunology, genomics, cardiology and diagnostics; among others. This has been made possible with the use of genetic engineering and a number of techniques like Immunohistochemistry (IHC), Fluorescent Microscopy, Cell Culture, Genetically Modified (GM) Cells, Monoclonal Antibodies (MAbs), Polymerase Chain Reaction (PCR) and Western blotting. The aim of this literature review is to explore the foundations and bases of the commonly used biomedical techniques, as well as their applications in biomedical research and clinical medicine in general.

Aetio-pathogenesis of breast cancer.

This is a literature review on the aetiology and pathogenesis of breast cancer, which is the most common cancer worldwide, and the second leading cause of cancer death, especially in Western countries. Several aetiological factors have been implicated in its pathogenesis, and include age, genetics, family history, diet, alcohol, obesity, lifestyle, physical inactivity, as well as endocrine factors. These factors act separately or together in the causation of breast cancer.

Effects of indomethacin on expression of PTEN tumour suppressor in human cancers.

Background: Previous studies reported that Non-steroidal Anti-inflammatory Drugs (NSAIDs), chemicals, and food supplements can be used to up-regulate the PTEN mRNA and protein expression, suggesting that these substances may be used in prevention and/or treatment of various human cancers like spinal, brain, colon, breast, prostate, bladder and endometrial cancers.

Aim: This was to study expression and sub-cellular localisation of PTEN protein, and review the effect(s) of indomethacin on PTEN's expression in cultured Human Endometrial Cancer (HEC 1B) cell line, which is known to express significant amounts of the wild-type PTEN.

Materials And Methods: This involves culture and incubation of artificial HEC 1B cells.

Phosphatase and tensin homologue deleted on chromosome 10.

Phosphatase and tensin homologue deleted on chromosome 10 (PTEN) is a tumor suppressor gene deleted or mutated in many human cancers such as glioblastoma, spinal tumors, prostate, bladder, adrenals, thyroid, breast, endometrium, and colon cancers. They result from loss of heterozygosity (LOH) for the PTEN gene on chromosome 10q23. Previous studies reported that various drugs, chemicals, and foods can up-regulate PTEN mRNA and protein expression in different cell lines, and they may be useful in the future prevention and/or treatment of these cancers.

A review of tip apex distance in dynamic hip screw fixation of osteoporotic hip fractures.

Fractured neck of femur is a common problem seen in elderly osteoporotic females, mostly in Western countries, among which are the extra-capsular fractures such as intertrochanteric and pertrochanteric fractures also known as peritrochanteric fractures, and commonly treated with dynamic hip screw (DHS) or compression hip screw (CHS). The DHS is based on tension band principle and allows the screw to slide within the barrel to enable compression of the fracture when the patient begins to bear weight. This principle only works in the presence of intact medial wall and so cannot be successful in a reverse oblique fracture of the proximal femur.
