Asthma treatment guidelines advocate the use of long-acting beta2-agonists (LABA) in addition to inhaled corticosteroids (ICS) in patients whose asthma is uncontrolled by ICS alone, thereby addressing two processes fundamental to asthma: bronchoconstriction and inflammation. Superior control--including a reduction in severe exacerbations--of asthma and COPD by ICS/LABA combination therapy has been demonstrated. Results from clinical studies suggest additive and potentially synergistic effects when the two agents are used in combination. ⋯ An ICS/LABA combination in a single inhaler represent safe, effective and convenient treatment options for the management of patients with asthma and COPD. Clinical results also suggest that adjustable dosing with budesonide/formoterol provides better asthma control than fixed dosing. Further elucidation of the underlying mechanisms responsible for this superior disease control is needed.

Fibromyalgia (FM) is continuing to be a challenging and confusing disorder for researchers and clinicians with its diverse symptoms, poorly understood etiology and pathophysiology. The use of multiple outcome variables reflecting the complexity of FM and co-morbid syndromes, makes it difficult to evaluate the efficacy or effectiveness of the treatment in clinical trials. Additionally researchers inevitably rely on patients' self-reported outcome data, which is prone to error and bias. ⋯ Consequently, clinicians and researchers have various highly validated and adequate outcome domains to assess FM symptoms and new researches continue to add new valuable domains. Nevertheless the current problem is to conclude, which treatment works best for whom and which are the outcome domains suitable for FM patients or patients' subgroups with different prominent features. Standardised and appropriate core outcome domains for FM clinical trails will encourage more complete investigations, relevant outcome reporting and well-designed multicenter trials.

Tuberculosis (TB) is a growing international health concern, since it is the leading infectious cause of death in the world today. In particular, the increasing prevalence of multidrug-resistant (MDR)-TB has greatly contributed to the increased difficulties in the control of TB. Because of the global health problems of TB, the increasing rate of MDR-TB and the high rate of a co-infection with HIV, the development of potent new anti-TB drugs without cross-resistance with known antimycobacterial agents is urgently needed. ⋯ In addition, the future development of new antitubercular drugs is briefly discussed according to the potential pharmacological targets. New critical information on the whole genome of Mycobacterium tuberculosis (MTB) was recently elucidated and increasing knowledge on various mycobacterial virulence genes will promote the progression in the identification of genes that code for new drug targets. Using such findings on MTB genome, drug development using quantitative structure-activity relationship may be possible in the near future.

Early postpartum hemorrhage remains a significant cause of maternal morbidity and mortality. Postpartum hemorrhage is most commonly due to uterine atony and often responds to medical treatments such as administration of uterotonic drugs, alone or in combination with uterine massage or bimanual compression. As the incidence of cesarean section continues to rise, the problem of placenta previa and accreta is likely to become more common. ⋯ In recent years new therapeutic measures to control the bleeding have gained attention. Although, these newer therapies focus on avoiding the need for emergency hysterectomy and preservation of reproductive function, reports of subsequent pregnancies are still scarce. Established management options are shortly reviewed and novel medical and surgical treatments are more extensively discussed.

Hypertension is the most common medical disorder during pregnancy. Approximately 70 percent of women diagnosed with hypertension during pregnancy will have gestational hypertension-preeclampsia. The term gestational hypertension-preeclampsia is used to describe a wide spectrum of patients who may have only mild elevation in blood pressure to those with severe hypertension with various organ dysfunctions (acute gestational hypertension, preeclampsia, eclampsia, and the syndrome of hemolysis, elevated liver enzymes, and low platelets (HELLP syndrome). ⋯ Treatment of mild gestational hypertension with antihypertensive medications has not been shown to improve outcome, however, in cases of severe disease treatment has been shown to be beneficial. The purpose of this review is to discuss the different treatment modalities used in the hypertensive disorders of pregnancy. Management strategies will not be discussed.
