Ten percent of people may experience pain under the heel (plantar heel pain) at some time. Injections, insoles, heel pads, strapping and surgery have been common forms of treatment offered. The absolute and relative effectiveness of these interventions are poorly understood. ⋯ Although there is limited evidence for the effectiveness of local corticosteroid therapy, the effectiveness of other frequently employed treatments in altering the clinical course of plantar heel pain has not been established in randomised controlled trials. At the moment there is limited evidence upon which to base clinical practice. Treatments that are used to reduce heel pain seem to bring only marginal gains over no treatment and control therapies such as stretching exercises. Steroid injections are a popular method of treating the condition but only seem to be useful in the short term and only to a small degree. Orthoses should be cautiously prescribed for those patients who stand for long periods; there is limited evidence that stretching exercises and heel pads are associated with better outcomes than custom made orthoses in people who stand for more than eight hours per day. Well designed and conducted randomised trials are required.

ReviewIbuprofen for the treatment of a patent ductus arteriosus in preterm and/or low birth weight infants.
A patent ductus arteriosus (PDA) complicates the clinical course of preterm infants, increasing their risks of developing chronic lung disease (CLD), necrotizing enterocolitis (NEC), and intraventricular hemorrhage (IVH). Indomethacin is used as standard therapy to close a PDA, but is associated with reduced blood flow to the brain, kidneys and gut. Ibuprofen, another cyclo-oxygenase inhibitor, may be as effective with fewer side effects. ⋯ We found no statistically significant difference in the effectiveness of ibuprofen compared to indomethacin in closing the PDA. Ibuprofen reduces the risk of oliguria. However, ibuprofen may increase the risk for chronic lung disease, and pulmonary hypertension has been observed in three infants after prophylactic use of ibuprofen. Based on currently available information ibuprofen does not appear to confer a net benefit over indomethacin for the treatment of a PDA. We conclude that indomethacin should remain the drug of choice for the treatment of a PDA. Future research may include a four arm trial where infants are randomized at birth, either to a prophylaxis arm starting at birth or to an arm in which treatment starts after a PDA is diagnosed by echocardiography within the first seven days of life. Within the prophylaxis and treatment arms, the infants would be randomized to either ibuprofen or indomethacin. The primary outcome should be intact survival (survival without handicap) at 18 months corrected age.

Biomechanical factors, such as reduced muscle strength and joint mal-alignment, have an important role in the initiation and progression of osteoarthritis (OA) of the hip or knee. Currently, there is no known cure for OA, however, disease-related factors, such as impaired muscle function and reduced fitness, are potentially amenable to therapeutic exercise. ⋯ Land-based therapeutic exercise was shown to reduce pain and improve physical function for people with OA of the knee. There were insufficient data to provide useful guidelines on optimal exercise type or dosage. Supervised exercise classes appeared to be as beneficial as treatments provided on a one-to-one basis.

ReviewEthosuximide, sodium valproate or lamotrigine for absence seizures in children and adolescents.
Absence seizures are brief epileptic seizures which present in childhood and adolescence. They are characterised by sudden loss of awareness and an electroencephalogram (EEG) typically shows generalised spike wave discharges at three cycles per second. Ethosuximide, valproate and lamotrigine are currently used to treat absence seizures. This review aims to determine the best choice of anticonvulsant for a child with typical absence seizures. ⋯ Although ethosuximide, lamotrigine and valproate are commonly used to treat people with absence seizures we have insufficient evidence to inform clinical practice, and the few trials included in this review were of poor methodological quality. More trials of better quality are needed.

ReviewIntra-cytoplasmic sperm injection versus conventional techniques for oocyte insemination during in vitro fertilisation in patients with non-male subfertility.
In vitro fertilisation (IVF) as treatment for male factor subfertility is associated with lower fertilisation and pregnancy rates than for other indications. Since the late 1980s several assisted fertilisation techniques have emerged and have been rapidly developed to try to enhance results for couples with male factor subfertility, or to help couples with severe male factor for whom conventional IVF was not possible. The techniques of partial zona dissection (PZD) and of subzonal microinjection of spermatozoa into the perivitelline space (SUZI) are by far surpassed by the technique of intra-cytoplasmatic sperm injection (ICSI). ICSI has proven to be the therapy of choice for couples with severe male factor subfertility. ⋯ Whether ICSI should be preferred to IVF for cases of non-male factor subfertility remains an open question. Further research should report livebirth rates and adverse events.
