ReviewCytotoxic drugs and interferons for chronic inflammatory demyelinating polyradiculoneuropathy.
Chronic inflammatory demyelinating polyradiculoneuropathy is a disease causing progressive or relapsing and remitting weakness and numbness. It is probably due to an autoimmune inflammatory process. Immunosuppressive or immunomodulatory drugs would be expected to be beneficial. ⋯ The evidence is inadequate to decide whether azathioprine, interferon beta or any other immunosuppressive drug or interferon is beneficial in chronic inflammatory demyelinating polyradiculoneuropathy.

Basal cell carcinoma (BCC) is the most common skin malignancy in humans. BCCs are defined as slow-growing, locally invasive, malignant (but not life threatening), epidermal skin tumours which mainly affect white skinned people. The first line treatment is usually surgical excision, but numerous alternatives are available. ⋯ There has been very little good quality research on efficacy of the treatment modalities used. Most of the trials have looked only at BCCs in low risk areas. Surgery and radiotherapy appear to be the most effective treatments with surgery showing the lowest failure rates. Other treatments might have some use but few have been compared to surgery. Imiquimod emerged as a possible new treatment although it has not been compared to surgery or any other modality.

Olanzapine is an atypical antipsychotic that is reported to be effective without producing the disabling extrapyramidal side effects associated with the older, typical antipsychotic drugs. ⋯ The large proportions of participants leaving the studies early, in the large multi-centre trials makes it difficult to draw firm conclusions on clinical effects. For people with schizophrenia olanzapine may offer antipsychotic efficacy with fewer extrapyramidal side effects than typical drugs but more weight gain. Large, long-term randomised trials with participants, interventions and primary outcomes that are familiar to those wishing to help those with schizophrenia are long overdue.

ReviewCommunication skills training for health care professionals working with cancer patients, their families and/or carers.
Research suggests communication skills do not reliably improve with experience and considerable effort is dedicated to courses improving communication skills for health professionals. The evaluation of such courses is of importance to enable evidence-based teaching and practice. ⋯ The training programmes assessed by these trials appear to be effective in improving cancer care professionals communication skills. It is not known whether the training would be effective if taught by other educators, nor has any trial compared the efficacy of both programmes.

ReviewNursing record systems: effects on nursing practice and health care outcomes.
A nursing record system is the record of care planned and/or given to individual patients/clients by qualified nurses or other caregivers under the direction of a qualified nurse. Nursing record systems may be an effective way of influencing nurse practice. ⋯ No evidence was found of effects on practice attributable to changes in record systems. Although there is a paucity of studies of sufficient methodological rigour to yield reliable results in this area, it is clear from the literature that it is possible to set up randomised trials or other quasi-experimental designs needed to produce evidence for practice. The research undertaken so far may have suffered both from methodological problems and faulty hypotheses. Qualitative nursing research to explore the relationship between practice and information use, could be used as a precursor to the design and testing of nursing information systems.
