Review Meta AnalysisDoxycycline for osteoarthritis of the knee or hip.
Osteoarthritis is a chronic joint disease that involves degeneration of articular cartilage. Pre-clinical data suggest that doxycycline might act as a disease-modifying agent for the treatment of osteoarthritis, with the potential to slow cartilage degeneration. This is an update of a Cochrane review first published in 2009. ⋯ In this update, the strength of evidence for effectiveness outcomes was improved from low to moderate and we confirmed that the symptomatic benefit of doxycycline is minimal to non-existent, while the small benefit in terms of joint space narrowing is of questionable clinical relevance and outweighed by safety problems. The CIs of the summary estimates now exclude any clinically relevant difference in improvement of symptoms and the small benefit in terms of joint space narrowing does not outweigh the harms.

Review Meta AnalysisClomiphene citrate in combination with gonadotropins for controlled ovarian stimulation in women undergoing in vitro fertilization.
Gonadotropins are the most commonly used medication for controlled ovarian stimulation in in vitro fertilization (IVF). However, they are expensive, invasive and are associated with risk of ovarian hyperstimulation syndrome (OHSS). With recent calls for patient friendly IVF, there has been an interest in the use of clomiphene citrate with or without gonadotropins to reduce the burden of injections. However, it is not known whether regimens using clomiphene are at least as effective as gonadotropins alone. ⋯ There was no evidence to indicate that clomiphene with gonadotropins (with or without GnRH antagonist) differed significantly from gonadotropins in GnRH agonist protocols for women undergoing IVF treatment, in terms of live births or pregnancy rates. Meanwhile, use of clomiphene led to a reduction in the incidence of OHSS. However, these results were based on data from a small number of underpowered randomised trials with few participants. Hence there was insufficient evidence to recommend use of clomiphene citrate in routine IVF practice. Larger trials with adequate power are required.

Review Meta AnalysisHorse chestnut seed extract for chronic venous insufficiency.
Conservative therapy of chronic venous insufficiency (CVI) consists largely of compression treatment. However, this often causes discomfort and has been associated with poor compliance. Therefore, oral drug treatment is an attractive option. This is an update of a Cochrane review first published in 2002 and updated in 2004, 2006, 2008 and 2010. ⋯ The evidence presented suggests that HCSE is an efficacious and safe short-term treatment for CVI. However, several caveats exist and larger, definitive RCTs are required to confirm the efficacy of this treatment option.

The mainstay of treatment of IgE-mediated cow milk allergy (IMCMA) is an avoidance diet, which is especially difficult with a ubiquitous food like milk. Milk oral immunotherapy (MOIT) may be an alternative treatment, through desensitization or induction of tolerance. ⋯ Studies to date have involved small numbers of patients and the quality of evidence is generally low. The current evidence shows that MOIT can lead to desensitization in the majority of individuals with IMCMA although the development of long-term tolerance has not been established. A major drawback of MOIT is the frequency of adverse effects, although most are mild and self-limited. The use of parenteral epinephrine is not infrequent. Because there are no standardized protocols, guidelines would be required prior to incorporating desensitization into clinical practice.

Diverticulitis is an inflammatory complication to the very common condition diverticulosis. Uncomplicated diverticulitis has traditionally been treated with antibiotics with reference to the microbiology, extrapolation from trials on complicated intra-abdominal infections and clinical experience. ⋯ The newest evidence from one RCT says there is no significant difference between antibiotics versus no antibiotics in the treatment of uncomplicated diverticulitis. Previous RCTs have only suggested a non-inferiority between different antibiotic regimes and treatment lengths. This new evidence needs confirmation from more RCTs before it can be implicated safely in clinical guidelines. Ongoing RCTs will be published in the years to come and more are needed. The role of antibiotics in the treatment of complicated diverticulitis has not been investigated yet.
