Postoperative morbidity was assessed in 100 patients who underwent minor gynaecological procedures. Fifty patients received intra-operative crystalloid (1000 ml compound sodium lactate solution) and the remaining fifty none. Identical short-acting intravenous anaesthetic techniques were used in both groups. There was no statistically significant difference between the groups in symptoms of nausea, vomiting, headache and drowsiness within the first 6 hours after operation. Patients who received intra-operative fluids exhibited a decreased incidence of dizziness within the first 6 hours and a decreased incidence of nausea when questioned at 3 days compared with those who did not receive any fluid; the difference was statistically significant.

The epidemiology, pathogenesis, clinical features, and treatment of Rocky Mountain spotted fever are reviewed. Rocky Mountain spotted fever is a severe infection caused by Rickettsia rickettsii transmitted to man by various species of ticks. High-incidence areas exist in the southeast and south central United States. Only 60-70% of patients with the disease report a history of tick bite or exposure to tick-infested areas. The disease is initially characterized by fever, headache, gastrointestinal complaints, myalgia, and a generalized rash. In several days generalized vasculitis may lead to periorbital edema and nonpitting edema of the face and extremities. Central nervous system involvement is common. Because signs and symptoms associated with the disease are nonspecific, the diagnosis is often delayed or missed. Traditionally diagnostic confirmation relied on serologic testing, but an indirect fluorescent antibody assay will soon be commercially available. Rocky Mountain spotted fever is usually treated with the rickettsiostatic agents chloramphenicol or tetracycline, but few comparative data on these agents in patients with the disease are available. For patients who cannot tolerate oral medications, intravenous chloramphenicol sodium succinate is the preferred treatment; chloramphenicol is also the drug of choice for children less than eight years of age. Otherwise, oral tetracycline hydrochloride is the drug of choice. Antibiotic therapy should be continued for 7-10 days or until the patient is afebrile for two to five days. All cases of Rocky Mountain spotted fever must be reported to the Centers for Disease Control. The best ways to decrease the morbidity and mortality of the disease are to increase awareness of its signs and symptoms and to prevent exposure to ticks.

Vasodilating antihypertensive drugs have in common the capacity to activate the peripheral sympathetic nervous system through the carotid sinus baroreceptor reflex mechanism, thereby increasing heart rate, renin release, and sodium and water retention. They differ in their tendencies to augment cardiac output and to relieve or precipitate cardiac failure and arrhythmias. Vasodilating antihypertensive drugs can produce an array of side effects and toxicity including headache, facial changes, hair growth, varying degrees of sodium and water retention, and rarely systemic lupus erythematosus and allergic reactions. Detailed knowledge of these effects is a prerequisite to skillful individualization of antihypertensive regimens.

Sinusitis is common in allergic children. We are now aware that the commonest presentation of this disorder in the pediatric age group is persistent cough and purulent rhinorrhea. Headache and facial tenderness, frequently noted in adults with sinusitis, are not common. Much remains to be learned about diagnostic techniques and therapy of sinusitis. Nasal cytology can be valuable for discriminating between allergic and infectious disease, but lacks both sensitivity and specificity. Although there is a high correlation between radiographs showing significant sinus membrane thickening or clouding and recovery of bacteria from antral taps, it is possible to see positive films in asymptomatic individuals. Similarly, films may be unremarkable, although the history and physical examination yield convincingly positive evidence for sinus infection. The clinician must sometimes decide on therapy when the diagnosis is not definitive. Antimicrobial therapy for sinusitis should be given for 3 to 4 weeks in many cases. Amoxicillin remains a good choice for therapy, but antibiotics capable of clearing infections by beta lactamase-producing bacteria should be considered in refractory situations. The value of antihistamines, decongestants, nasal steroids, and cromolyn sodium are unstudied at this time. If several antibiotic courses fail to alleviate the signs and symptoms of sinusitis, surgery is indicated. Antral lavage and creation of nasoantral windows is the usual approach in children. Patients with sinusitis often have concurrent middle ear disease. Patients with current sinusitis have a higher incidence of immunoglobulin disorders than found in a normal pediatric sample. It appears that patients with sinusitis are more often allergic than would be expected from 2 typical population distribution. More evaluation is needed to clarify these associations.

A double-blind, placebo-controlled crossover trial was undertaken to determine the efficacy of meclofenamate sodium in the treatment of menorrhagia. Twenty-nine patients who had a baseline menstrual blood loss greater than 60 ml received 2 months' each of meclofenamate sodium, 100 mg by mouth, three times a day, or a placebo. The mean menstrual blood loss was reduced from 141.6 +/- 15.9 ml at baseline to 69.0 +/- 6.3 ml during treatment cycles but remained increased during placebo cycles (135.6 +/- 11.3 ml). The symptoms of dysmenorrhea, backache, and headache were significantly reduced only during active drug periods. The number of days of flow and pads or tampons used was also reduced during drug cycles but not during placebo cycles. Overall, 26 of the 29 patients evaluated had a reduction in menstrual blood loss with the use of meclofenamate sodium. It appears that many women with unexplained menorrhagia may benefit from this treatment.

The frequency of headache after Picolax (sodium picosulphate, Nordic Ltd) preparation for barium enema was investigated and its association with dehydration, as assessed by haemoconcentration, was determined. Eleven out of 41 patients (26.8%) complained specifically of headaches. Although patients with and without headaches developed significant increases in haemoglobin concentration after Picolax preparation, the rise in haemoglobin in those with headaches was significantly greater than in those without (P less than 0.05). In both groups the haemoglobin concentration returned to normal after a bowel washout. These results suggest an association between dehydration and headache developing after a Picolax regimen. It may be possible to prevent this symptom by advising on the intake of specific volumes of fluid during preparation for barium enema.

Despite the widespread use of non-steroidal anti-inflammatory drugs (NSAIDs), the current number of reported cases of poisoning is small. However, with the introduction of 'over-the-counter' preparations of NSAIDs in some countries (e.g. ibuprofen in the UK and USA) an increased incidence of acute poisoning from this group of drugs can be expected. Conventionally, NSAIDs are divided into the following groups based on their chemical structure: arylpropionic acids, indole and indene acetic acids, heteroarylacetic acids, fenamates, phenylacetic acids, pyrazolones and oxicams. Unless NSAIDs are ingested in substantial overdose, acute poisoning with these agents does not usually result in significant morbidity or mortality. In most cases the clinical features are mild and confined to the gastrointestinal and central nervous systems, though acute renal failure, hepatic dysfunction, respiratory depression, coma, convulsions, cardiovascular collapse and cardiac arrest may complicate severe poisoning. Arylpropionic acid derivatives were thought initially to have a low order of toxicity in overdose but, in addition to anticipated gastrointestinal symptoms, headache, tinnitus, hyperventilation, sinus tachycardia, hypoprothrombinaemia, haematuria, proteinuria and acute renal failure have been described. In addition, drowsiness, coma, nystagmus, diplopia, hypothermia, hypotension, respiratory depression and cardiac arrest have been reported in severe cases of poisoning. Oxyphenbutazone and phenylbutazone are considerably more toxic in overdose. Complications of severe poisoning include coma, convulsions, hepatic dysfunction, acute renal failure, sodium and water retention, haematuria, cardiovascular collapse, respiratory alkalosis, metabolic acidosis, hypoprothrombinaemia and thrombocytopenia. In contrast, indomethacin appears to be much less toxic. In addition to gastrointestinal symptoms, indomethacin taken in overdose induces headache, tinnitus, dizziness, lethargy, drowsiness, confusion, disorientation and restlessness. Only 1 case of acute sulindac poisoning has been reported in the literature. A 16-year-old boy was admitted with hypokalaemia (2.2 mmol/L), transient granulocytosis and 'scanty' haematemesis after ingesting 12 g sulindac. No case of acute tolmetin poisoning have been reported. The fenamates (flufenamic acid, meclofenamic acid, mefenamic acid, tolfenamic acid) are, with the exception of mefenamic acid, not as widely prescribed as other groups of NSAIDs. In overdose, mefenamic acid may result in nausea, vomiting, diarrhoea, muscle twitching, convulsions and coma.(ABSTRACT TRUNCATED AT 400 WORDS)

A previously healthy 26-year-old man presented with fever, headache, skin rash, and thrombocytopenia. Cultures of blood and cerebrospinal fluid yielded a fastidious gram-negative bacillus, identified as DF-2. A unique feature of this case was the presence of a false-positive latex agglutination result for cryptococcal antigen in the cerebrospinal fluid in the absence of pleocytosis. Additional laboratory studies, which included indirect immunofluorescence and sodium dodecyl sulfate-polyacrylamide gel electrophoresis, however, failed to reveal common antigenic surface components between these organisms.

A patient who had experienced water intoxication despite normal renal function and normal urinary diluting ability was observed during the initiation stage of hyponatremia. Upon the excessive water intake (10 to 15 L) for several days, he developed moderate hyponatremia (121 mEq/L) and headache, an early symptom frequently seen in water intoxication. During this period, his urine was maximally dilute (50 to 60 mOsm/kg H2O), and his urinary sodium excretion increased. This report suggests that 10 to 15 L of water intake for several days can cause water intoxication in subjects with normal urinary diluting ability and that the increase in sodium excretion is prerequisite for the high urine flow rate.

Thirty (2.5%) of 1200 consecutive patients with a first stroke had a spontaneous dissection with occlusion of the cervical internal carotid artery (ICA). A suggestive picture with ipsilateral headache and oculosympathetic paresis was uncommon (17%), so that diagnosis was uncertain before angiography. Seven patients died within one week. During follow-up (mean, 3.2 years) with sequential Doppler ultrasonographic testing, 12 survivors had a good recovery and early reopening of the occluded ICA, and 11 had a poor recovery usually without reopening of the ICA. Recurrence of a dissection occurred in only one patient. Large infarcts causing death or a severe disability were associated with an ICA thrombus and distal emboli; the organization of this intraluminal thrombosis may explain the absence of reopening in these cases while resorption of the intramural hematoma developed. Early heparin sodium therapy may help prevent intraluminal clotting without carrying an important risk of extending the dissection, but its clinical benefit remains unproven. Contrary to current opinions, ICA dissection with occlusion causing cerebral infarction may often carry a severe prognosis.
