[S2e guideline of the German urologists: Conservative and pharmacologic treatment of benign prostatic hyperplasia]. / S2e-Leitlinie der Deutschen Urologen : Konservative und medikamentöse Therapie des benignen Prostatasyndroms.

This report summarizes the relevant aspects of the S2e guideline of the German Urologists for the conservative and pharmacological treatment of lower urinary tract symptoms due to benign prostatic hyperplasia. Recommendations are given regarding watchful waiting, behavioral therapy, phytotherapy and pharmacological mono- and combination therapy. The influence of the different therapeutic options on bladder outlet obstruction (BOO) is described in detail.

[S2e guideline of the German urologists: Instrumental treatment of benign prostatic hyperplasia]. / S2e-Leitlinie der Deutschen Urologen : Instrumentelle Therapie des benignen Prostatasyndroms.

This report summarizes the relevant aspects of the S2e guideline of the German Urologists for the instrumental treatment of the lower urinary tract symptoms due to benign prostatic hyperplasia. Recommendations are given regarding open and transurethral procedures (TUR-P, bipolar TUR-P, TUI-P, HE-TUMT, TUNA, and the different Laser techniques). Recommendations are also given concerning intraprostatic stents and injection therapies. The influence of the different therapeutic options on bladder outlet obstruction (BOO) is described in detail.

[Outpatient specialist medical care: what is possible, what will come?]. / Ambulante spezialfachärztliche Versorgung : Was geht, was wird kommen?

The guidelines on outpatient specialist medical treatment (ASV) according to § 116b of the Social Act were published by the Federal Joint Committee on 21 March 2013. The guidelines regulate the framework conditions for the new area of healthcare and the requirements for potential participants. The ASV guidelines are designed to ultimately bridge the sectorial borders for the treatment of rare diseases and those with unusual courses. In the past the reforms in § 116b have not fulfilled the criteria expected by the legislation. The reforms have already led to an increase in the costs for medical services by a factor of 50 within 6 years. The spectrum of diseases to be treated has remained practically unchanged. The healthcare providers must now fulfil a catalogue of prerequisites which will be formulated by the Federal Joint Committee for each entity in the still to be provided annexes to the guidelines in order to be approved on notification by the extended National Committee. The guidelines are based on the prototype further education regulations according to the old law. An important detail is the obligatory formation of cooperation and teams for all participants outside the traditional sectorial limits. Each partner must perform the duties at least 1 day in the week at the site of the team leader. Specific and organizational requirements, extent of treatment and lower limits will be regulated by the still to be formulated annexes. Costing and business effectiveness will be tested by the medical services. No patient has yet been treated under the ASV but the winner is already known: bureaucracy.

[Pain therapy in acute renal colic.]. / Schmerztherapie der akuten Nierenkolik.

The severe pain of a renal colic is an emergency and requires a fast and sufficient analgesic therapy with few side-effects. The release of the ureteral obstruction is secondary to this initial treatment. Inhibition of prostaglandin synthesis directly interferes with the mechanism of renal colic pain. Dipyrone, indomethacin and diclofenac are the drugs of choice. They should be administered intravenously if possible. Narcotic agents and their derivatives are the second choice. Spasmolytic agents are unnecessary in the treatment of renal colic.

Monitoring of liver oxygenation during neuroleptanalgesia in the dog.

In an animal study (7 mongrel dogs) the effects of neuroleptanalgesia (NLA) and combinations of NLA with nitrous oxide (N2O) and isoflurane on the macro- and microcirculation of the liver were investigated. Measurements were made in three steps. After NLA alone the dogs were supplementarily ventilated with nitrous oxide/oxygen at a ratio of 2:1. During the last step, 1 MAC isoflurane was added to the inspired gas. From the portal vein, arterial and mixed-venous systems' hemodynamic parameters, blood gases, and acid-base balance were recorded. As a parameter of oxygenation the tissue PO2 of the liver was measured with a multiwire surface electrode. During NLA stable hemodynamic conditions and a balanced acid-base status were observed. The nitrous oxide combination resulted in an increase of the mean pulmonary artery pressure of 16%. The addition of isoflurane had a negative inotropic effect: The heart index decreased to 74% of the starting value and the total peripheral resistance (TPR) increased by 27%. The summarized PO2 histograms under NLA and NLA/N2O showed arithmetic mean values of 34.1 and 35.2 mm Hg, respectively. The addition of isoflurane resulted in a left shift and a decrease of the mean value to 28.6 mm Hg. This histogram corresponds exactly to the oxygen pressure distribution in the dog liver during piritramide basic anesthesia. It seems that NLA and the combination of NLA/N2O increase the liver perfusion with a higher portal-venous and tissue PO2. This effect can be explained only by a massive change of visceral circulation. It is canceled by the addition of isoflurane.
