In a series of 136 cases of hydatid disease affecting various tissues and organs admitted to one surgical unit in the Medical City Hospital, Baghdad, and personally studied and treated by the author, the liver was involved in 94 cases (69-1 per cent) and intrabiliary rupture occurred in 15. Pain in the right upper abdominal quadrant associated with tenderness and rigidity, radiating to the back and right, shoulder, was the presenting feature in almost all the patients. Hectic fever was present in 14. Obstructive jaundice developed in all the patients at some stage of the illness, but was complete with clay-coloured stools in only half. Chills and rigors were present in 67 per cent, eosinophilia in 40 per cent, a positive Casoni's test in 87 per cent, itching with urticaria and weal formation in 20 per cent and a palpable mass in the liver in 67 per cent of cases. Operative treatment is mandatory in order to clean the mother cyst of hydatid membranes, debris and daughter cysts, to explore and clear the common bile duct and to ensure free biliary passage to the duodenum. Sphincterotomy is neither necessary nor advisable, and when the gallbladder is not invaded by the cyst it should be preserved.

Trichomonas vaginalis is a flagellate protozoon which in women commonly causes vaginal itching; burning, and a frothy, offensive and seropurulent yellowish discharge. Incidence of infection in women varies from 13 to 60%, and is highest during pregnancy because of excess estrogens and in women with poor hygiene or with vaginitis. In men, the incidence ranges from 9 to 37% of persons with urethral discharge. This study presents the results of the use of a single dose treatment of Trichomonas vaginitis with 2.0 gm Tinidazole. 350 women with vaginal discharge from the Gynecology Dept. of Cairo University hospitals were studied. Microscopic study of the discharge revealed T. vaginalis in 103 cases (aged 17 to 48 years). Majority of the clinical complaints (pruritus vulvae; soreness; sense of fullness in vagina and dysuria) disappeared in all cases after administration of 2.0 gm single dose of Tinidazole. Discharge; dyspareunia and soreness or pain at vulval interoitus disappeared in about 2/3 of cases; improved in about 1/4 and persisted in less than 8% (failure in these cases was attributed to other causes such as cervical erosion; bacterial infections; hormonal or other pathologic lesions in the internal genitalia). Mild gastrointestinal reaction (nausea and vomiting) were observed in 5 cases and transient urticaria in 1 case.

This article reviews the effect of H1 antihistamines on the pruritus of urticaria, from articles in which their therapeutic effect on chronic idiopathic and physical urticaria is assessed. In limited studies available pruritus improved concomitantly with wealing by an average of two thirds, though the response in individual patients was variable. In some physical urticarias the pruritus and wealing showed disproportionate improvement compared to erythema. The minimally sedating H1 antihistamines were as effective or more effective than classical H1 antihistamines. The dose of antihistamines that totally abolished a histamine weal only partly reduced urticarial weals (therefore by inference also of the associated pruritus). Additional therapy aimed at pruritogenic mediators other than histamine would be expected to improve urticarial pruritus.

Exercise is a physical cause of allergic reactions, including exercise-induced anaphylaxis (EIAna), exercise-induced urticaria (EIU), exercise-induced asthma (EIA), and exercise-induced rhinitis (EIR). Since its first description in 1979, EIAna has been reported with variable clinical manifestations, with exercise alone, and in combination with food ingestion. Elevated serum histamine levels and cutaneous mast cell degranulation have been noted. Exercise-induced urticaria appears as small, punctate lesions that differ from the classic coalescent type seen with EIAna. Variant forms of EIAna with cholinergic urticarial lesions manifesting systemic collapse and/or respiratory distress have been studied. Exercise-induced urticaria and cold-induced urticaria may cause elevated plasma histamine levels coincident with the onset of pruritus and hives. Theories accounting for EIA include respiratory heat loss, water loss, and mast cell activation. Although some studies have shown increased plasma histamine with EIA, others have not. Recently, bronchoalveolar lavage in atopic subjects with EIA has been evaluated preexercise and postexercise, with no significant differences in histamine or tryptase, suggesting a pathogenesis of EIA independent of the mast cell. Exercise-induced rhinitis, with varying degrees of rhinorrhea, congestion, and sneezing, has been increasingly recognized in athletes who run, cycle, and ski. Cold-air-induced rhinorrhea in laboratory challenges displays a mediator release pattern similar to that produced by allergen-induced nasal challenges. Therapeutically, H1 antihistamines are recommended for EIAna both as pretreatment and acute therapy. H1 antihistamines may be helpful in EIU, but are recommended for EIAna both as pretreatment and acute therapy.(ABSTRACT TRUNCATED AT 250 WORDS)

The twofold purpose of this study was to assess the prevalence of latex sensitivity in a large group of operating room nurses and to evaluate the relationship between questionnaire responses and skin tests. Of the total target population of 268 operating room nurses, 248 (93%) answered the questionnaire and 197 had skin prick tests to latex (1/10 wt/vol solution). Symptoms associated with glove wearing were acknowledged by 41.1% of nurses. Skin tests to latex were positive in 21 nurses (10.7%), 4.4 times more often in atopic nurses. Among nurses complaining of local symptoms, only 18.6% had positive skin tests. Itching of the hands during glove wearing correlated poorly with latex sensitivity, but correlation with local urticaria was better. Atopic nurses complaining of urticaria had latex allergy in 70% of cases. Thus latex allergy is common in nurses, especially atopic nurses. A questionnaire is unreliable in predicting latex sensitivity and must be supported by latex skin test. More data will be needed to assess the risk of anaphylactic perioperative reactions in operating room nurses.

Exercise-induced anaphylaxis (EIA) is a unique form of physical allergy that has been recognized with increasing frequency in recent years. The hallmarks of this syndrome are generalized pruritus with a flushing sensation, a feeling of warmth, and the development of urticaria in association with vigorous physical exertion. These symptoms tend to occur variably with exercise, but not with passive warming. Most patients report typical giant urticarial eruptions. Skin mast cells degranulate, and serum histamine increases during symptomatic attacks. Treatment is often problematic, but cessation of exercise with onset of symptoms and self-administration of epinephrine are recommended.

Protective latex surgical gloves and examination gloves may cause allergic contact dermatitis, mainly due to rubber chemicals used in the manufacturing process. Latex proteins in the gloves may cause contact urticaria and even anaphylactoid reactions. Eighty-eight dentists and other members of the dental team were tested for contact allergy to thiuram- and mercapto-derivatives, and for contact-urticaria to latex proteins. All but 5 persons used gloves at least periodically. Fifty-one of 87 of the persons who answered a questionnaire had or had had symptoms from the skin on the hands, but in only 3 cases could allergy to the gloves be proved. Women had more often symptoms than men, and female dentists with symptoms used gloves more often and for longer periods than female dentists without symptoms. It can be concluded that redness of the skin, itching, vesicles and eczema are common symptoms reported in connection with use of gloves, but proved allergy to the gloves is rare. Most symptoms are supposed to be due to skin irritation from the gloves in addition to irritative exposure from handwashing and other chemical irritants in dental work. The nature of the irritative effect from gloves is only partly known and should be studied further.

The efficacy and safety of a new non-sedating antihistamine, loratadine (Clarityn, CAS 79794-75-5) 10 mg q.d., was compared to the classical antihistamine, hydroxyzine 25 mg t.i.d. and placebo in a 4-week (optional 12 week) randomized, double-blind, multi-center study in 203 patients with chronic idiopathic urticaria. Efficacy evaluations included weekly physician and patient assessments of pruritus, overall disease condition, and therapeutic response to treatment. Loratadine and hydroxyzine were significantly more effective than placebo and clinically comparable to each other as measured by all efficacy evaluations at each visit. Loratadine was safe and well tolerated with sedation and dry mouth similar to placebo and significantly less than hydroxyzine.

Dimetindene maleate (DMM, Fenistil, CAS 3614-69-5) a specific H1-receptor antagonist, is therapeutically used for the treatment of respiratory allergies, urticaria, itching dermatoses and generally pruritic sensations occurring with various diseases. As it exhibits local anaesthetic activity in the rabbit cornea and the local anaesthetic activity of a couple of H1-antagonists was found to be linearly correlated to the H1-potency represented by the pA2-values--and dimethindene maleate demonstrates a high pA2-value--it seemed worth investigating the local anaesthetic potency in man making use of an objective and well validated pain model, the Laser algesimetry. The study was carried out with 24 healthy volunteers in a double-blind placebo- and reference-controlled, randomized, cross-over design. Three different medications were applied with occlusive dressing: DMM, lidocaine, and placebo. Selective thermo-noxious stimulation of A-delta- and C-fibers was induced by a CO2-laser. Somato-sensory evoked vertex potentials (SEPs) were simultaneously recorded. Both verum treatments showed a remarkable analgesic potency compared to placebo. Effects were preferably concentrated on the peripheral N1-component of the SEPs. The overall means of the N1-amplitudes were suppressed compared to placebo by both active drugs, with the effects being more pronounced for DMM.

In a multicenter, randomized, investigator-blinded trial, patients were randomly selected to receive either cefpodoxime proxetil or amoxicillin-clavulanate potassium orally for the treatment of acute suppurative otitis media. Patients were seen before, during, and at the end of therapy, and 2 to 3 weeks after completion of therapy. A total of 229 patients, 153 receiving cefpodoxime and 76 receiving amoxicillin-clavulanate were entered into the study; all patients were examined to determine drug safety. A total of 146 patients, 98 in the cefpodoxime group and 48 in the amoxicillin-clavulanate group, completed the study and were examined to determine drug efficacy. End-of-therapy microbiologic eradication rates in assessable patients were 92% for cefpodoxime and 86% for amoxicillin-clavulanate (p = 0.14; 95% confidence interval (CI) on difference: -4.4%, 19.2%). End-of-therapy clinical response rates for assessable patients were as follows: cured, 68% for cefpodoxime and 65% for amoxicillin-clavulanate; improved, 24% for cefpodoxime and 23% for amoxicillin-clavulanate; and failed, 8% for cefpodoxime and 13% for amoxicillin-clavulanate (p = 0.57; 95% CI: -8.4%, 16.5%). Recurrence rates at long-term follow-up were 24% for cefpodoxime-treated patients and 25% for those given amoxicillin-clavulanate. Both drugs were well tolerated; 20.9% of those given cefpodoxime and 31.6% of amoxicillin-clavulanate-treated patients had drug-related adverse medical events (p = 0.102; 95% CI: -23.9%, 2.6%). Gastrointestinal complaints were the most frequently reported drug-related side effect in both groups: 11.8% of cefpodoxime-treated patients and 21.1% of those given amoxicillin-clavulanate (p = 0.076; 95% CI: -20.8%, 2.2%). Drug-related dermatologic side effects (e.g., diaper rash, pruritus, urticaria) were reported in 7.8% of cefpodoxime-treated patients and 14.5% of those who received amoxicillin-clavulanate (p = 0.160; 95% CI: -16.6%, 3.3%). Our findings suggest that clinical efficacy for cefpodoxime administered twice daily is equivalent to that of amoxicillin-clavulanate administered three times a day.
