Benign prostatic hyperplasia (BPH), nonmalignant enlargement of the prostate, can lead to obstructive and irritative lower urinary tract symptoms (LUTS). The pharmacologic use of plants and herbs (phytotherapy) for the treatment of LUTS associated with BPH has been growing steadily. Cernilton, prepared from the rye-grass pollen Secale cereale, is one of the several phytotherapeutic agents available for the treatment of BPH. ⋯ The Cernilton trials analyzed were limited by short duration, limited number of enrollees, gaps in reported outcomes, and unknown quality of the preparations utilized. The comparative trials lacked a proven active control. The available evidence suggests Cernilton is well tolerated and modestly improves overall urologic symptoms including nocturia. Additional randomized placebo and active-controlled trials are needed to evaluate the long-term clinical effectiveness and safety of Cernilton.

ReviewProphylactic natural surfactant extract for preventing morbidity and mortality in preterm infants.
This section is under preparation and will be included in the next issue. ⋯ Prophylactic intratracheal administration of natural surfactant extract to infants judged to be at risk of developing respiratory distress syndrome (intubated infants <30 weeks gestation) has been demonstrated to improve clinical outcome. Infants who receive prophylactic natural surfactant extract have a decreased risk of pneumothorax, a decreased risk of pulmonary interstitial emphysema, a decreased risk of mortality, and a decreased risk of bronchopulmonary dysplasia or death.

ReviewTimed intercourse versus intra-uterine insemination with or without ovarian hyperstimulation for subfertility in men.
Although intra-uterine insemination (IUI) is widely used, however its effectiveness remains a matter of debate. Although IUI is less invasive and expensive than IVF or GIFT, it should only be applied if the probability of conception is improved significantly as compared to the natural chance of conceiving. To increase the number of available oocytes at the site of fertilization, controlled ovarian hyperstimulation (COH) can be applied in conjunction with IUI. Uncontrolled studies suggest a beneficial effect of COH in combination with IUI, also when a male factor is present. To be able to draw firm conclusions whether IUI and/or COH improve the probability of conception, several comparisons should be performed in randomized controlled trials (RCTs). ⋯ Intra-uterine insemination offers couples with male subfertility benefit over timed intercourse, both in natural cycles and in cycles with COH. In the case of a severe semen defect (with more than 1 million motile sperm after semen preparation and no triple sperm defect) IUI in natural cycles should be the treatment of first choice. The value of COH need to be further investigated in RCTs. Mild ovarian hyperstimulation with gonadotrophins is advised in cases with less sever

ReviewZuclopenthixol acetate in the treatment of acute schizophrenia and similar serious mental illnesses.
People with schizophrenia or other psychotic illnesses may have delusions or hallucinations that may lead them to be aggressive or violent to themselves or others. Medication that is used in this context require the properties of rapid onset of effect (tranquillisation or at least initial sedation in order to quell aggressive or disorganised behaviour, but also antipsychotic effect), low frequency of administration and low levels of side effects, such as cardiological or neurological side effects, or pain at the injection site. Zuclopenthixol is the cis(Z)-isomer of clopenthixol, a neuroleptic of the thioxanthene group, used for treating people with psychotic symptoms. There is one oral preparation and two depot forms: zuclopenthixol acetate and zuclopenthixol decanoate. The acetate version does not stay in the body for very long (a single dose persists for only 72 hours) and is said to have these properties. ⋯ Recommendations on the use of zuclopenthixol acetate for the management of psychiatric emergencies in preference to 'standard' treatment have to be viewed with caution. Most trials present important methodological flaws and findings are poorly reported. This review did not find any suggestion that zuclopenthixol acetate is more effective in controlling aggressive/disorganised behaviour, acute psychotic symptoms, or preventing side effects. There were no data directly related to tranquillisation, but it may produce more earlier and intense sedation than oral haloperidol. Well conducted randomized controlled trials are needed to confirm claims related to the use of zuclopenthixol acetate in emergency psychiatry.

ReviewAntibiotic prophylaxis regimens and drugs for cesarean section.
Prophylactic antibiotics for cesarean section have been shown to reduce the incidence of maternal postoperative infectious morbidity. Many different antibiotic regimens have been reported to be effective. ⋯ Both ampicillin and first generation cephalosporins have similar efficacy in reducing postoperative endometritis. There does not appear to be added benefit in utilizing a more broad spectrum agent or a multiple dose regimen. There is a need for an appropriately designed randomized trial to test the optimal timing of administration (immediately after the cord is clamped versus pre-operative).
