The existence of a relationship between inhibition of prostaglandin biosynthesis and analgesic or anti-inflammatory activity was investigated in the case of the non-narcotic analgesics glafenine, floctafenine and clometacine, in comparison to indomethacin and acetylsalicylic acid. These compounds inhibit prostaglandin biosynthesis from arachidonic acid in a guinea-pig lung homogenate as strongly as indomethacin. On its biosynthesis in rat epididymal tissue stimulated by noradrenaline, glafenine equals indomethacin inhibitory potency, whereas floctafenine and clometacine are less active. Acetylsalicylic acid is the least active in both preparations. In vivo, prostaglandin biosynthesis induced in rat peritoneal fluid by injection of acetic acid is inhibited by the 5 drugs, ranked as follows: floctafenine greater than indomethacin greater than glafenine greater than clometacine greater than acetylsalicylic acid. The pharmacological profile of glafenine, floctafenine and clometacine is characterized by a relatively strong effect on acetic acid writhing and a relatively weak effect on carrageenin oedema, U.V. erythema and adjuvant arthritis. The inhibition of prostaglandin biosynthesis seems better correlated with their analgesic activity than with their anti-inflammatory effects. The results show that prostaglandins could play an important role in the genesis of tissulary pain in animals.

In children aged 15--16 years receiving routine reinforcement tetanus immunisation, adsorbed vaccine caused more severe and more frequent local reactions than did plain formol toxoid, and a higher incidence of pyrexia. The incidence of swelling and erythema at the inoculation site increased with serum antitoxin titre at the time of inoculation, whereas pain and tenderness were related to the presence of the aluminium hydroxide adjuvant. Both vaccines gave satisfactory antibody responses over a 5-month observation period; plain formol toxoid induced higher mean titres than did the adsorbed vaccine. It is recommended that plain and not adsorbed vaccine be used when reinforcement of immunity to tetanus alone is desired.

The authors report a series of 9 cases of meningoradiculitis after tick bites and compare them with 56 other cases in the literature. Clinically, the bite is followed by a free interval, then more or less extensive local erythema, pain then paralysis is undoubtedly the most typical presentation. Uni- or bilateral paralysis of the 7th cranial nerve was found in more than 50% of cases. Erythema may exceptionally be absent. There may be forms with pain alone. Finally, there may sometimes be pyramidal signs or signs of brain irritation. As concerns the course, one should note the absence of respiratory complications, and although there are usually no or minimal sequelae, one should note the slowness of the recovery in certain paralytic cases. In the laboratory, pleocytosis is constantly found in the C.S.F. As concerns physiopathology, there are 3 theories, virus, allergic and toxic.

We performed daily examination of 80 patients with recurrent herpes simplex labialis to define the course of the disease and to identify quantitative and objective measurements for use in monitoring the efficacy of antiviral chemotherapy. Pain, lesion size, mean virus titers from lesion swabs (10(5) plaque-forming units [PFU]) and frequency of virus-positive lesions (89 per cent) were maximal during the first 24 hours and decreased thereafter. Lesion punch-biopsy virus titers increased from a mean of less than 10(1) PFU in the prodromal and erythema stages to a mean of 10(4.7) in the vesicle stage. MEasurements potentially useful in monitoring antiviral efficacy include: time to loss of crust, time to complete healing, intensity and duration of lesion pain, area defined by lesion virus titer and duration of lesion virus excretion, and maximum lesion virus titer after the first visit. Early application of topical antiviral therapy should theoretically be able to alter the course of this disease.

A double-blind placebo controlled trial was carried out in 14 steroid-dependent patients with rheumatoid arthritis to assess the effectiveness and steroid-sparing action of flurbiprofen over a 4-week period. During the first week, the patients' steroid dosage was stabilized at the minimum necessary to control symptoms. They were then treated with either 100 mg flurbiprofen or placebo 3-times daily for 3 weeks. Steroid dosage was initially reduced to 50% of the stabilized dose and reduced further if practicable, depending on therapeutic response. Clinical assessments were made, at weekly intervals, of pain, swelling, tenderness, erythema, range of movement, grip strength, walking time, and duration of morning stiffness. Joint scanning of 99mTc uptake was also measured before and after treatment in 11 patients. The results showed that whereas 3 out of 6 patients on placebo has distinct inflammatory flare-up, this did not occur in any of the 8 patients on flurbiprofen. Moreover, 3 of the flurbiprofen group showed improvement and a further reduction in steriod dosage was possible in 3 patients. Improvements in joint scans correlated well with the clinical findings in 6 of 11 patients.

The efficacy of topical applications of povidone-iodine (Betadine solution and ointment) for the control of infection associated with decubitus and stasis ulcers was evaluated in 18 male outpatients (age range, 33--68 years). Dressings were changed twice daily over a period of 42 days. Statistically significant improvement was noted in the following signs and symptoms: edema, pain, erythema, ulcer size, and ulcer depth. All patients experienced some degree of symptomatic relief and clinical improvement within two weeks after starting therapy. At the end of the study, 67 percent of the ulcers were clinically cured and 33 percent showed improvement. Acceptance by the patients was excellent, with no reported side effects or sensitization reactions. Povidone-iodine used in a daily regimen of ulcer care can reduce the level of infection and promote healing.

A review of 100 patients with peripheral septic phlebitis revealed that 54 per cent of the cases were due to intravenous catheters and 46 per cent were secondary to drug abuse. Eighty per cent of the involved veins were in the arm or neck. Pain was the most common symptom (83 per cent), with erythema and edema the most common physical signs (63 per cent). Eighty per cent of the causative organisms were gram-positive bacteria, usually Staphylococcus aureus (41 per cent) or Group A streptococcus (20 per cent). Complications were more common if septic phlebitis was due to intravenous therapy than drug abuse. No deaths were directly attributed to septic phlebitis. However, hospital stay after development of septic phlebitis was 14 days with a 56 per cent complication rate. The initial treatment of septic phlebitis should include prompt removal of the intravenous device, antibiotics, heat, and elevation. Because serious complications occur in a significant number of patients, operative excision of the involved vein should be performed if clinical deterioration occurs or if septicemia persists after 24 hours despite conservative therapy.

Erythromelalgia is an extraordinary disorder of unknown etiology and pathophysiology that resembles the post-traumatic reflex dystrophy syndromes but has not been described previously in the orthopedic literature. Its distinctive triad of intense burning extremity pain associated with erythema and increased skin temperature are diagnostic. Primary or idiopathic and a secondary or associated form have been identified. The latter occurs in association with an underlying disease process, especially myeloproliferative disorders. Treatment with pharmacologic agents and surgery are ineffective except in the secondary group where treatment of the associated disorder generally results in a remission. Symptoms in the primary group can be minimized by appropriate environmental control with cooling and avoiding heat-producing situations that would raise skin temperature above a critical thermal threshold.

To assess the etiologic role of C. trachomatis and other microorganisms in idiopathic epididymitis, 23 men underwent microbiologic studies, including cultures of epididymal aspirates in 16. 11 of 13 men under age 35 had C. trachomatis infection whereas 8 of 10 over age 35 had coliform urinary tract infection. Cultures of epididymal aspirates yielded C. trachomatis alone in 5 of 6 men under 35, and coliform bacteria alone in 5 of 10 over 35. These results suggests that C. trachomatis is the major cause of idiopathic epididymitis, and coliform bacteria the major cause of epididymitis in older men. Expressible urethral discharge and inguinal pain were more common in the chlamydial cases, whereas concurrent genitourinary abnormality and scrotal edema and erythema occurred more commonly in the coliform cases. The morbidity attributable to C. trachomatis is as serious as that attributable to Neisseria gonorrhoeae.

Necrosis of the skin is a rare complication of oral anticoagulation therapy by coumarin congeners. Three males receiving prophylactic warfarin anticoagulation therapy following cardiac valve replacement and one female similarly receiving anticoagulation drugs because of bilateral deep thrombophlebitis associated with carcinoma of the pancreas had typical skin necrosis develop. The lesions passed rapidly through stages beginning with pain, edema, erythema and petechiae. Ecchymoses followed in the localized area with a large bullae containing deep red fluid. Biopsy of the skin revealed involvement of the dermovascular loops with localized necrosis from extensive occlusion of dermal capillaries and venulae by fibrin thrombi. There was red cell extravasation, but inflammatory changes were inconstant. In the patients, in our study, the involvement ranged from small localized lesions of the trunk to extreme extensive skin involvement of both legs with full thickness necrosis in areas. This condition is not dose related nor the result of simple hypoprothrombinemia. It appears to be a conditioned and localized toxicity, although hypersensitivity has not been excluded. Once the diagnosis is made, orally administered anticoagulant drugs must be stopped immediately, and heparinization may be beneficial in confining the process.
