Effective therapy (Rx) in primary hypertension (PH) for 50 years, has featured sympathetic nervous system (SNS) mechanisms. Ganglionic blockers and reserpine were pre-eminent in the 1940s (mydriasis, ileus, impotence, peptic ulcer). Guanethidine, and in the 1960s clonidine and methyldopa, were step II agents to thiazide Rx in the 1950s. Reserpine depletes brain (depression) and peripheral (PPH) noradrenaline (NA) storage sites, guanethidine depleted NA storage via blockade of reuptake. Venomotor sympathoplegia resulted in postural hypertension. An analogue, metaiodobenzyguandine is used in diagnosis and Rx of pheochromocytoma. Clonidine lowers both central and PPH neuronal NA release via both stimulation of alpha agonist adrenoreceptors (sedation) and specific imadazoline binding sites (IBS). Methyldopa lowers pressure via PPH induced NA release (retrograde ejaculation) and via alphamethyl NA on central alpha-2 receptors (depression). The alpha-2 and alpha-2 receptor antagonists (alphaRA) cause reflex tachycardia and first-dose hypotension. Recently a two-fold incidence of congestive heart failure after alphaRA in treated primary hypertensives question their role in PH. The beta RA, with or absent alphaRA, remain premier since the 1970s due to mortality benefit in systolic dysfunction and post myocardial infarction, certifying the role of the SNS in the pathogenesis and sequelae and Rx of PH. The future includes beta RA, specific IBS agents, angiotensin (AII) RA with avid presynaptic AII affinity and vasopeptidase inhibitiors that raise peptides and suppress SNS.

The key points of this article are anorexia and cachexia are: A major cause of cancer deaths. Several drugs are available to treat anorexia and cachexia. Dyspnea in cancer usually is caused by several factors. Treatment consists of reversing underlying causes, empiric bronchodilators, cortico-steroids--and in the terminally ill patients-opioids, benzodiazepines,and chlorpromazine. Delirium is associated with advanced cancer. Empiric treatment with neuroleptics while evaluating for reversible causes is a reasonable approach to management. Nausea and vomiting are caused by extra-abdominal factors (drugs,electrolyte abnormalities, central nervous system metastases) or intra-abdominal factors (gastroparesis, ileus, gastric outlet obstruction, bowel obstruction). The pattern of nausea and vomiting differs depending upon whether the cause is extra- or intra-abdominal. Reversible causes should be sought and empiric metoclopramide or haloperidol should be initiated. Fatigue may be caused by anemia, depression, endocrine abnormalities,or electrolyte disturbances that should be treated before using empiric methylphenidate. Constipation should be treated with laxatives and stool softeners. Both should start with the first opioid dose.

Living donor liver transplantation evolved in response to donor shortage. Current guidelines recommend potential living donors (LD) have a body mass index (BMI) <30. With the current obesity epidemic, locating nonobese LD is difficult. From September 1999 to August 2003, 68 LD with normal liver function test (LFTs) and without significant comorbidities underwent donor hepatectomy at our center. Post-operative complications were collected, including wound infection, pneumonia, hernia, fever, ileus, biliary leak, biliary stricture, thrombosis, bleeding, hepatic dysfunction, thrombocytopenia, deep venous thrombosis, pulmonary embolism, difficult to control pain, depression and anxiety. Complication rates for LD with BMI >30 (n = 16) and BMI <30 (n = 52) were compared. The incidence of wound infection increased with BMI, 4% for nonobese and 25% for obese LD (p = 0.024). There were no statistically significant differences for all other complications. No LD died. Recipient survival was 100% with obese LD and 80% with nonobese LD (p = 0.1). Select donors with a BMI >30 may undergo donor hepatectomy with acceptable morbidity and excellent recipient results. Updating current guidelines to include select LD with BMI >30 has the potential to safely increase the donor pool.

Duodenitis-proximal jejunitis (DPJ) is an idiopathic condition in the horse characterized by inflammation and oedema of the duodenum and proximal jejunum. Clinical signs include colic, ileus, depression, fluid accumulation in the small intestine and stomach, and endotoxaemia. The objective of this study was to investigate prospectively the role of Clostridium difficile in this idiopathic disease. Nasogastric reflux from 10 consecutive cases with DPJ and 16 consecutive horses with other causes of nasogastric reflux was cultured for C. difficile, other Clostridium spp., and Salmonella. Toxigenic strains of C. difficile were isolated from 10/10 (100%) of horses with DPJ and 1/16 controls (P<0.0001). No other known pathogenic clostridia were isolated from either group. Results of this study suggest that C. difficile might be an important cause of this syndrome.

Potent opioids are excellent painkillers but their use is hampered by side-effects such as nausea, vomiting, bowel dysfunction, urinary retention, pruritus, sedation and respiratory depression. Co-analgesics are often combined with opioids to reduce the prevalence of these unwanted effects while maintaining or even improve the quality of analgesia. A search of the recent literature demonstrated that peripheral opioid antagonists are able to reduce opioid-induced bowel dysfunction without interfering with analgesia. Dexmedetomidine, gabapentin, and ketamine significantly reduce opioid consumption but have no effect on the incidence of opioid side-effects. In contrast, intravenous lidocaine and corticosteroids not only produce an opioid-sparing but also a significant reduction in the occurrence of postoperative ileus and nausea and vomiting. It remains unclear whether the perioperative use gabapentin, ketamine and corticosteroids has an effect on the development of postsurgical chronic pain states.

Methods for managing pain after a total hip replacement have changed substantially in the past 5 years. We documented the outcome of patients treated with a multimodal pain program designed to avoid parenteral narcotics. Avoidance of parenteral narcotics can essentially eliminate the complications of respiratory depression, ileus, and narcotic-induced hypotension. It can minimize nausea and vomiting which cause dissatisfaction with an operation. Twenty-one of 140 patients (15%) needed parenteral narcotics postoperatively with only nine patients (6.4%) using parenteral narcotics after the day of surgery. Mean pain scores were below 3 of 10 on all postoperative days. There were no patients with respiratory depression or ileus, and four (2.9%) with urinary retention. Nausea occurred with 35 patients (25%) in the recovery room and in 28 patients (20%) thereafter. Emesis occurred in five patients (3.6%) with two incidences in the recovery room. One hundred and thirty-eight patients (98.6%) were discharged home at a mean of 2.7 seven days postoperatively with 98 (70%) on a single assistive device. The multimodal pain management program, which avoided parenteral narcotics, was effective in providing pain relief, nearly eliminating emesis, and eliminating the severe complications of respiratory depression, urinary tract infection and ileus, as well as accelerating function.

First- and second-generation antipsychotics commonly cause mild and sometimes severe gastrointestinal motility depression. We discuss a case of a patient who developed paralytic ileus during his treatment with a combination of second-generation antipsychotics. The patient did not receive other medication that could cause depression of intestinal motility than the above-mentioned combination of antipsychotics and no other etiology could be found for the ileus. Furthermore we discuss the theoretical background of antipsychotics induced gastrointestinal motility depression and we provide the literature review of case reports of this topic.

Pain is a common occurrence for the hospitalized elderly, and may often be under recognized and inadequately managed. Insufficient pain management can lead to the sequelae of emotional distress and depression, delirium, anxiety, sleep disturbances, and physical disabilities, as well as increased health care costs. Effective pain management of the older adult begins with pain assessment using the proper tools. Morphine is the analgesic of choice for the older adult, and is appropriate for the postoperative period. It is important to maintain a therapeutic serum level of opioids to prevent inadequate management of the acute pain. Side effects of opioids include hypotension, nausea, mood disturbances, ileus, histamine production, and respiratory depression. The adage for pain treatment in the elderly is "start low and go slow". Paracetamol is commonly prescribed and may be the drug of choice for mild to moderate postoperative pain. Older adults may enjoy the benefits of Patient-Controlled Analgesia and Patient Controlled Epidural Analgesia in the postoperative period; however, thorough and ongoing teaching must occur to ensure understanding and compliance with the therapy. Treating post-procedure pain in the elderly patient requires an understanding of the normal changes associated with aging and the impact on medications, and multimodal analgesia can be the best approach.

For thousands of years mu opioid agonists such as morphine have been utilized for their analgesic properties. Today, morphine and related compounds are still used as a first line therapy in the treatment of moderate to severe pain. However, despite the clear benefits of mu agonists in pain management, severe side effects such as dependence and respiratory depression are associated with use of these drugs. To date, there are only two approved mu opioid antagonists for use in the treatment of these adverse effects, that is, naloxone and naltrexone. However, many other clinical and therapeutic areas have been linked to mu opioid receptor antagonism. These include treatment of opioid induced pruritus of the skin, obesity, and Parkinson-induced tardive dyskinesia. Currently there are two compounds, N-methylnaltrexone and alvimopan, under FDA review as possible treatments for opioid induced bowel dysfunction and postoperative ileus. These compounds are of special interest as they are peripherally restricted. This attribute enables treatment of peripheral side effects induced by opioid agonists without reversal of the centrally mediated analgesia of the agonist. In this article we discuss the structural classes of mu opioid antagonists, their potential clinical applications, and review the relevant patents of the last ten years.

WHO describes palliative care as the approach to patients with incurable illnesses. It covers identification and treatment of pain and other physical symptoms, psychological, social, and spiritual difficulties. A tight cooperation between the family doctor, the hospital (medical clinic with the subspecialists, geriatric and palliative care centre), the Spitex, the social, psychological, and the pastoral workers is needed. The family doctor needs to know much about medication and specific interventions in order to alleviate the patients' symptoms such as pain, breathlessness, cough, difficulties to swallow, nausea, vomiting, constipation, ileus, nutritional problems, fear, depression, and fatigue. The specific interventions may include irradiation, stenting of bile ducts, oesophagus or colon, hormonal treatment etc. A very important aspect is pain control and the correct handling of non-opioid analgesics, opioids, and co-analgesics. The terminal phase at home is a special challenge for the family doctor acting as a palliative physician.
