ReviewControlling sialorrhoea: a review of available treatment options.
Sialorrhoea (drooling or excessive salivation) is a common symptom of many neurological diseases (e.g., amyotropic lateral sclerosis, cerebral palsy and Parkinson's disease) and otolaryngologic diseases (tumours of upper aerodigestive tract). It is mostly caused by poor oral and facial muscle control in patients with swallowing dysfunction (secondary sialorrhoea). However, some cases of sialorrhoea are due to hypersecretion of saliva. These cases represent so-called primary sialorrhoea.

Haemophilia B is an inherited bleeding disorder associated with a deficiency of coagulation factor IX. The hallmark of the severe phenotype is recurrent and spontaneous bleeding into joints, which can lead to joint deformity and arthritis at an early age. ⋯ Conventional treatment now consists of the administration of recombinant factor IX concentrate on a prophylactic basis to prevent bleeds and, hence, minimise disability in the long term. Trials of gene therapy are also underway, but these are in the very early stages and will not be a realistic option for at least another 20 years.

Novel therapies to treat invasive fungal infections have revolutionised the care of patients with candidiasis, aspergillosis and other less common fungal infections. Physicians in the twenty first century have access to safer versions of conventional drugs (i.e., lipid amphotericin B products), extended-spectrum versions of established drugs (i.e., voriconazole), as well as a new class of antifungal agents; the echinocandins. The increased number of options in the antifungal armamentarium is well timed, as the incidence of both invasive candidiasis and invasive aspergillosis, and the financial burden associated with these infections, have increased significantly in the past several decades. ⋯ Unfortunately, the overall survival rate among patients treated with amphotericin B, and even voriconazole, remains suboptimal, as evidenced by the failure of treatment in 47% of patients in the landmark voriconazole versus amphotericin B trial. Given the increasing incidence and suboptimal outcomes of these serious fungal infections, novel therapies represent an opportunity for significant advancement in clinical care. The current challenge is to discover the optimal place for the echinocandins in the treatment of invasive fungal infections.

Hot flushes, the most common health problem reported by menopausal-age women, can lead to significant morbidity and affect the social life, ability to work and sleep pattern of the sufferer. Women treated for breast cancer and men receiving androgen ablation for prostate cancer experience hot flushes that are more frequent, severe and longer lasting than those experienced by the general menopausal population. In women with breast cancer, hot flushes can result from chemotherapy-induced menopause, hormonal therapy, or ovarian suppression. ⋯ However, recent studies have shown that, in healthy menopausal women, hormone replacement therapy is associated with an increased risk of breast cancer, myocardial infarction, thrombo-embolic events and stroke. Thus, identifying nonhormonal agents that can control hot-flush symptoms is essential to the quality of life of a growing population of cancer survivors. The most promising agents act on the CNS and include selective serotonin reuptake inhibitors, as well as venlafaxine and gabapentin.

ReviewMonoclonal antibody therapy for central nervous system lymphomas: an emerging treatment paradigm.
The management of CNS lymphomas is poised for another revolution due to the emergence of therapeutic monoclonal antibodies. As the technology for generating monoclonal antibodies matures and obstacles are solved, therapeutic monoclonal antibodies will play an increasing role in the management of cancer. This article will review the biology of CNS lymphomas, monoclonal antibody technology, limitation of existing chemotherapies and the application of therapeutic monoclonal antibodies for the treatment of CNS lymphomas.
