Plasma and 24-h urinary adenosine 3':5'-monophosphate (cyclic AMP) and guanosine 3':5'-monophosphate (cyclic GMP) were measured by radioimmunoassay in 12 normal subjects, 33 patients with six types of non-neoplastic disease (cholelithiasis, peptic ulcer, coronary heart disease, hypertension, regional ileitis, and cirrhosis), and 34 patients with five types of disseminated neoplastic disease (acute myelocytic leukemia; Hodgkin's disease; and metastatic cancer of the lung, colon, and breast). In patients with non-neoplastic disease, cyclic nucleotide values in plasma and urine did not differ significantly (P greater than 0.05) from those in normal subjects. In patients with disseminated cancer, cyclic AMP values in plasma and urine likewise did not differ significantly from those in normal subjects. Plasma cyclic GMP, in contrast, was significantly elevated in all five types of cancer patients, and urinary cyclic GMP was significantly elevated (five times the normal mean) in patients with acute myelogenous leukemia and Hodgkin's disease.

Analgesic abuse is a major public health hazard in Australia, and analgesic nephropathy with consequent terminal renal failure is the underlying cause in 20% of the patients requiring dialysis and transplantation. Analgesics are invariably taken in the form of compounds and mixtures. In the aspirin-phenacetin-caffeine (APC) mixture, aspirin appears to be the major nephrotoxic agent and phenacetin appears to play a secondary and synergistic role. The renal disease associated with abuse of analgesics is characteristic and is part of a much wider clinical syndrome, the analgesic syndrome, which includes peptic ulcer disease (35%), anemia (60 to 90%), hypertension (15 to 70%), ischemic heart disease (35%), psychological and psychiatric manifestations, pigmentation, and possible gonadal- and pregnancy-related effects. The primary lesion in analgesic nephropathy is renal papillary necrosis (RPN), and this is a nephrotoxic effect common to all nonsteroid antiinflammatory agents. The most important factor in the management of patients with analgesic nephropathy is the cessation of analgesic abuse, and this leads to improvement and stabilization of renal function. A small proportion of patients will, however, deteriorate in relation to accelerated hypertension, persistent proteinuria, ischemic heart disease, and complications leading to nephrectomy. Patients with analgesic nephropathy are poor risk patients and have a poor prognosis, even after dialysis and transplantation.

Yearly measurements of external noise (Noise--Pollution--Level) in the shipyard in Stettin, indicated noise levels above 85 dBA, expressed in LqM. On the ground of documentation of periodic medical examinations of the staff, one compared the rate of occurrence of disturbances in health state, such as: hearing impairment, gastric and duodenal peptic ulcer, hypertension and psychic disturbances in two groups of employees: "A"--exposed during work to noise 85 dBA and "B"--employed at the area of LqM smaller by 20 dBA. Statistically significant differences in the rates of occurrence of disturbances in the health state were found, to the disadvantage of those exposed to noise effect. In these groups also the rate of sickness absenteeism was disadvantageous: in the last 14 years its average values for the shipyard surpassed the average rate for Stettin district and the whole country.

Dyspepsia may result from over-indulgence in alcohol and food, or from anxiety and emotional problems. It may also indicate a peptic ulcer, oesophagitis or less commonly, gallstones or gastric cancer. Investigation by endoscopy or barium studies is always indicated when an organic lesion is suspected. Reassurance, tranquillizers and antispasmodics help patients with functional dyspepsia. Antacids given hourly between meals are important in the treatment of all symptomatic peptic ulcers. Cimetidine causes rapid symptomatic relief of duodenal ulcer symptoms, and most ulcers will heal with six weeks' therapy. Gastric ulcer can be treated with carbenoxolone, but this drug is avoided in the elderly and in patients with cardiac failure or hypertension. Anticholinergic drugs are of value in duodenal ulcer, especially for night pain, but they should not be used in patients over the age of 50. Special diets are of no value. For the heartburn of oesophagitis, weight reduction and a regime of regular antacid therapy remain the important measures.

Because of the multiplicity of disease conditions and diminished tolerance for drugs in the aged, it is necessary to know concomitant pathologic conditions to determine which antihypertensive drug to use. In the Philadelphia Geriatric Center, there are about 1,000 residents, between 70 and 100 years of age. About 40% have hypertension; almost 50% have or once had depression; there are many cases of hiatal hernia and/or peptic ulcer; in one subdivision of residents, almost 40% have renal disease with BUN above 30 mg/100 ml. In antihypertensive treatment, some individuals respond fairly well to reassurance and weight reduction, when obese, even without drugs. All are given a low-salt diet. A diuretic is first used--thiazide in cases of good renal function, furosemide with impaired renal function. Liquid potassium supplements are given. If there is but little reduction in blood pressure in several weeks, methyldopa is added in ascending doses, in cases with or without renal impairment. In hypertension with impaired renal function, furosemide and/or methyldopa were especially valuable. Furosemide as an antihypertensive drug was also noted to delay the onset of congestive heart failure. Since reserpine can aggravate peptic ulcer and can precipitate or aggravate depression, it should seldom be used to treat hypertension in the aged. Guanethidine is rarely used, since it can cause cerebrovascular insufficiency and marked weakness. High blood pressure should be reduced slowly in the aged, to avoid untoward effects.

The analgesic syndrome, comprising renal disease, hypertension, peptic ulcer, anaemia and recurrent headache, accounts for wide-spread morbidity and mortality especially in Queensland and New South Wales. Epidemiological and clinical evidence gathered from many Western societies implicates unsupervised consumption of compound analgesic preparations, particularly those containing phenacetin, in the causation of the majority of cases. Laboratory experiments so far have failed to produce an entirely satisfactory model of clinical analgesic nephropathy. In small animals, papillary necrosis results from prolonged feeding with large doses of aspirin and a number of other anti-inflammatory agents more readily than when phenacetin, paracetamol or phenazone is given alone. The apparently conflicting deductive and experimental data may be reconciled if, as indicated by preliminary observations, salicylates enhance the toxicity of phenacetin derivatives. In planning a programme of prevention for the analgesic syndrome, the central aetiological role of non-narcotic drug dependency must be recognized. As the analgesics to which addiction commonly occurs are the compound powders and tablets, or those containing a stimulant, these preparations should be available only in circumstances where their use can be monitored. Suspected unsupervised and unwarranted consumption of analgesics should be checked by urinary testing for drug metabolites. Because the underlying problem of analgesic dependency is behavioural and environmental in origin rather than medical, the physician must combine forces with the social engineer to devise a definitive solution for this condition.

A 52 year old man with a long history of marked hypertension, peptic ulcer disease, nephrocalcinosis and intermittent hypercalcemia was referred to be evaluated for primary aldosteronism suspected on the basis of low plasma renin activity, hypokalemia and blood pressure responsive to spironolactone. Aldosterone excretion, however, was extremely low. Alkaluria, high urinary sodium excretion and hypercalciuria were observed. The patient admitted to chronic ingestion of large amounts of baking soda. Upon cessation of alkali abuse, his blood pressure fell dramatically; orthostatic hypotension, concomitant azotemia, hemoconcentration, hyperkalemia and weight loss occurred. Despite dramatic elevation in plasma renin activity, urinary aldosterone excretion remained low during this period. Adrenal glucocorticoid secretion was intact. All abnormalities of sodium, potassium and aldosterone subsequently returned to normal. A 10 day challenge with oral sodium bicarbonate was associated with a rise in blood pressure, but serum calcium remained normal. The patient remains normotensive 15 months after discontinuing alkali abuse.

Published controlled studies of various psychotherapeutic techniques in psychosomatic disorders with adequate designs have formed the basis for the following conclusions: Psychotherapeutic techniques are effective in some patients with psychosomatic disorders. Some psychosomatic disorders, for example, bronchial asthma, peptic ulcer, and migraine headaches are perhaps more amenable to psychotherapy than others, for example, hypertension and ulcerative colitis. There is evidence to suggest that there are differences between the effectiveness of various psychotherapeutic techniques; a few patients differ perhaps from the rest in that they are helped most by the technique that is less effective for the majority.

The introduction of dinoprost tromethamine (Prostin F2 Alpha) as an abortifacient in the second trimester of pregnancy represents the first clinical use of a prostaglandin. Various synthetic analogues of the naturally occurring derivatives are being employed investigationally in the treatment of peptic ulcer, hypertension, asthma, and hypercalcemia. In the United States, dinoprost tromethamine is primarily administered intra-amniotically. Despite the fact that a substantial number of patients experience allergic reactions, hypertension, bronchospasm, nausea, vomiting, cramps, and diarrhea, the efficacy and relative safety of dinoprost tromethamine establish it as superior to intra-amniotic instillation of hypertonic saline. Cervical laceration, laceration or rupture of the lower uterine segment, retention of the placenta, and hemorrhage in part reflect the intensity of uterine contraction induced by dinoprost. Experience in administration improves the therapeutic response and diminishes adverse reactions.
