Two groups of 20 patients each were given immediately after hip-operation an epidural injection of 0,15 or 0,3 mg buprenorphine. Effects and side effects are compared with those observed in two groups of patients having the same type of operation, and given either 4 mg of morphine or saline (placebo) by epidural injection. Buprenorphine in both doses produced a shorter duration of analgesia than 4 mg of morphine. In no case did respiratory depression occur. Urinary retention after buprenorphine was barely more frequent than in the placebo group. Nausea and vomiting occurred in 35-45% of patients. We do not see an advantage in replacing morphine by buprenorphine for epidural opiate-analgesia, because the same high rate of nausea/vomiting is associated with a significantly shorter duration of analgesia after buprenorphine. We are convinced that epidural opiate-analgesia is most valuable for postoperative pain relief but should be reserved for selected cases.

Oral contrceptives (OCs), usd by over 30% of reproductive aged women in Belgium, are by far the most widely used contraceptive in that country. The various types of OCs include monophasic, biphasic, and triphasic combinations of an estrogen and a progestin, sequentials containing estrogen only for 7-14 days followed by a progestin through the 21st day; macrodose or microdose progestin only formulations, 3-month injectable progestins, and the morning after pill. Side effects of OCs are mainly due to metabolic effects on coagulation factors, the renin-angiotensin system, glucose tolerance, or the lipid profile. Users of OCs face increased risks of cholelithiases, thrombophlebitis, thromboembolism, cerebrovascular accidents, myocardial infarcts (among smokers over 35 years of age), and hepatic adenomas. The most troubling secondary effect is the excess cardiovascular morbidity and mortality show by contraceptive users, not just those who are obese, hypertensive, or who have histories of vascular pathology, but also those over 40 years of age and smokers. Lenght of use of OCs does not increase vascular risks. Epidemiologic studies demonstrate that vascular risks are reduced in lower dose formulations. Absolute contraindications to OC use include serious cardiovascular problems, severe hepatic pathology, estrogen-dependent tumors, pregnancy and undiagnosed gynecologic problems, and significant hyperlipidemia. Relative contraindications include severe headaches, cholelithiase, previous cholestasis of pregnancy, severe renal disease, fibromyomas, benign breast disease, age over 40 years, smoking, surgery anticipated within 4 weeks, infectious mononucleosis, falciform anemia, and immediate postpartum and lactation. Epilepsy, diabetes, depression, and varicose veins are not strictly speaking contraindications but require additonal surveillance. Lower dose formulations should be prescribed if possible. OC users should be followed up every 6-12 months. Among other steroidal contraceptive methods, sequential OCs and high dose progestin-only formulations are used for short-term treatment of specific conditions. Progestin-only minipills are used when an OC is desired but estrogens are contraindicated. Injectable progestins should be reserved for patients who for cultural or medical reasons can use no other type of contraceptive. Morning-after pills should not be considered a regular form of contraception. If OCs are used in adolescents, a low dose pill is indicated. Low dose OCs may be indicated for diabetics because of the danger of infection with IUDs and the lesser efficacy of barrier methods. If OCs are used in epileptics, they should be regular dosed because of the danger of drug interactions. Only low-dose formulations and progestin-only minipills should be used by women over 40.

The dexamethasone suppression test (DST) was developed from the neuroendocrine research strategy to provide indirect information about the integrity of the limbic system in patients with endogenous depression (ED). Abnormal test results occur in close temporal relationship to clinical episodes of ED, but not during the intervals between episodes. The neuroendocrine disinhibition revealed by the test is not a trait marker of individuals predisposed to develop ED. A standardized DST procedure has been established and can be applied in outpatient or inpatient routine clinical practice, with good sensitivity (50-65%) and high specificity (96%). The conditional probability principles of interpreting the test results are discussed and the effect of prevalence on the predictive value of the test results is emphasized. The DST should not be used as a screening test for all psychiatric patients but should be reserved for cases where clinical indications for its use are present. These indications include diagnostic confirmation of ED, monitoring the response to treatment, prediction of relapse or new episodes, and possibly prediction of suicide risk in patients with ED. The test may be especially useful in the diagnostic assessment of patients with difficult or confusing presentations of ED such as catatonia, depressive pseudodementia, depression in adolescents or children, "masked" depression, depression complicated by a personality disorder, and schizoaffective depression.

Vasopressin produced analgesia in mice as estimated by using abdominal constriction tests (ED50 8.5 micrograms/kg i.v.) or hot plate method (ED50 63 micrograms/kg i.v.). However, vasopressin (10 micrograms/kg i.v.) produced no depression of locomotor activity in mice. Vasotocin had slight analgesic action; oxytocin or norepinephrine had none and there was no direct correlation between pressor response and analgesia. The analgesic action was nonopiate in nature as it was uninfluenced by the narcotic antagonist naltrexone at 5 to 15 mg/kg, but it was reserved by a vasopressin antagonist. Intraventricular administration of vasopressin (1-10 micrograms/kg) to mice produced no significant analgesia, suggesting a primarily peripheral locus of analgesic action. Vasopressin may play a role as an endogeneous pain regulating substance.

In 32 patients subjected to total hip replacement, postoperative pain relief was achieved by random treatment with either 5 mg of morphine in 10 ml of saline (n = 15) or 6-8 ml of 0.5% bupivacaine with epinephrine (n = 17), both drugs administered by the lumbar epidural route. In an additional group of 10 patients, post-traumatic thoracic or post-operative abdominal pain was relieved first by 4-6 ml of 0.5% bupivacaine with epinephrine and subsequently by 5 mg of morphine in 10 ml of saline, both drugs being administered by the thoracic epidural route. The duration of analgesia was significantly longer, on average, with morphine (28 h) than with bupivacaine (4.3 h) when the drugs were given by the lumbar route. Thoracic administration of morphine also resulted in a significantly longer duration of pain relief (on average 9.8 h) than that of bupivacaine (3.8 h). Morphine gave satisfactory pain relief in all cases. It was not associated with motor block, loss of sensitivity to temperature, touch, or pin-prick, or any signs of sympathetic block, as was the case with epidural bupivacaine. Plasma concentrations of morphine were not detectable 8 h after injection, though the patients still had pain relief. One case of delayed severe respiratory depression occurred 6 h after morphine injection via the thoracic route. Epidural morphine analgesia should therefore be reserved for patients in whom continual surveillance is possible, at least until more is known about the pharmacokinetics of narcotics in the epidural and subarachnoid space.

Psychoemotional stress induces in healthy individuals increased serum Ig and C3 subunit of complement. Response of B immunity psychoemotional stress remains within the limits of basic functioning. State of B immunity in psychologic comfort condition insignificantly depends on individual psychology. Uniqueness on individual immune reactions in psychoemotional stress presents depression of reserved B lymphocytes, which could be easily seen in people of controversial personality type.

The observed response to 131I-metaiodobenzylguanidine (MIBG) therapy in advanced neuroblastoma after conventional therapy, the non-invasiveness of the procedure, and the high metabolic activity which is frequently observed in untreated tumours led to the concept of substituting 131I-MIBG therapy for combination chemotherapy at diagnosis prior to surgery in patients with advanced disease/high-risk neuroblastoma. The objective of introducing 131I-MIBG therapy as the first therapy in the treatment schedule is to reduce the tumour volume, enabling adequate (> 95%) surgical resection of the tumour and to avoid toxicity and the induction of early drug resistance. The advantages of this approach are that the child's general condition is unaffected or improved before it undergoes surgical resection and that chemotherapy is reserved to treat minimal residual disease postoperatively. Thirty-one children who presented with inoperable neuroblastoma (10 Evans stage III, 21 stage IV) were treated according to this protocol. The objective response to the 131I-MIBG therapy at diagnosis with respect to the volume of the primary tumour, the metastases and catecholamine excretion in urine varied from 72 to 81%, which is better than after conventional treatment. Nineteen of 27 evaluable patients (70%) had complete or > 95% resection of the primary tumour or did not require surgery at all. Only 11 of 31 patients developed isolated thrombocytopenia and, despite the fact that the bone marrow was invaded in 16 patients, moderate bone marrow depression occurred in only two cases.(ABSTRACT TRUNCATED AT 250 WORDS)

Thrombolytic treatment and aspirin will save about 50 in 1000 patients treated for acute myocardial infarction, but with a risk of cerebral or other serious bleeding in two to three in every 1000. Early treatment (< 4 h) about halves mortality; the benefits decline with time but are clearly proven up to 12 h from onset. Benefit is best and risk least when there is ST elevation and bundle branch (BB) block on the initial ECG. Hypotension is not a contraindication. There is no clear benefit from treatment of patients with ST depression, T wave change or a normal ECG. Streptokinase (SK), tissue plasminogen activator (tPA) or APSAC are equally effective with no mortality benefit for any of the drugs. SK is safer, particularly in older or more hypertensive patients. tPA is reserved for patients who have received SK during the previous year, when high antibody titres may neutralize its effect on a second myocardial infarction (MI). Heparin (either i.v. or high dose S/Q) added to aspirin may confer some small additional benefit, but at the cost of significantly increased risk of bleeding. It should be reserved for high risk patients. Routine angioplasty is unhelpful. Investigation should be reserved for patients with continuing symptoms or ECG evidence of ischaemia, at rest or after stress testing. The benefits of thrombolysis are seen at all ages, in both sexes, and whatever the site of the MI. Aspirin 75-100 mg daily should be continued long-term.

Obstructive sleep apnea syndrome may be just an annoyance to an affected person's bed partner, or it can be a more serious and even dangerous condition for the person involved. One clue to the condition is daytime somnolence, although not all sleepy patients have the syndrome. If obstructive sleep apnea syndrome is confirmed by a polysomnogram, a trial of nasal continuous positive airway pressure (NCPAP) is warranted. If daytime somnolence is unaffected, then it is unlikely that the syndrome is the sole cause of the patient's sleepiness. Alternative diagnoses (eg, narcolepsy, atypical depression) should then be considered. Surgery, orthodontic devices, and pharmacotherapy are generally less effective than NCPAP and are usually reserved for patients who cannot tolerate NCPAP. Surgical techniques may be best suited for patients who have clearly defined craniofacial abnormalities and those who cannot tolerate NCPAP. Weight reduction to near ideal body weight and avoidance of benzodiazepines, opiates, and alcohol should be emphasized in all patients with suspected or confirmed sleep apnea.

In the 10 years since our previous review of this topic, the acute coronary syndromes (Q wave myocardial infarction [QMI], non-Q wave MI [NQMI], and unstable angina) have been more clearly categorized. Many of the differences delineated between QMI and NQMI still hold: a less extensive infarction and a lower in-hospital mortality, but a larger degree of jeopardized myocardium leading to a higher incidence of reinfarction and recurrent angina. The pathophysiology of NQMI appears to be similar to that of unstable angina except for the greater incidence and extent of thrombus formation and coronary artery occlusion with NQMI. Prognostic studies have shown that ST depression and anterior infarct location are associated with a greater risk for posthospital clinical events than the findings of ST elevation and other infarct locations. Symptom-limited stress testing using electrocardiogram and thallium-201 imaging are now recommended before discharge or in the early postdischarge period, with coronary arteriography recommended for evidence of residual ischemia. Aspirin and low dose heparin should be administered on admission after NQMI to decrease further thrombus formation, and aspirin continued in the posthospital period. Diltiazem administration is recommended in NQMI without evidence of pulmonary congestion to prevent recurrent nonfatal acute myocardial infarction. Percutaneous transluminal coronary angioplasty and surgical revascularization should be reserved for patients with NQMI with residual ischemia.
