A 25-year-old white female returned from West Africa with a two-year history of epidosic swelling, pruritus, and pain in a wrist, associated with peripheral eosinophilia. Serologic and immediate skin tests with Dirofilaria immitis antigen were positive, and blood smears transiently showed microfilariae of Acanthocheilonema perstans after the patient had been treated with diethylcarbamazine. Before treatment, both the serum concentration of IgE and the eosinophil content of arylsulfatase, an enzyme that selectively inactivates slow-reacting substance of anaphylaxis, were elevated; the patient's peripheral leukocytes released histamine and eosinophil chemotactic factor of anaphylaxis when challenged with D. immitis antigen. After one course of diethylcarbamazine, the clinical manifestations and abnormal in vitro immunologic results resolved. Host response to A. perstans infection appears to involve both IgE-mediated hypersensitivity and alterations in an eosinophil enzyme.

A controlled, double-blind comparison of naphalzoline hydrochloride 0.05%, antazoline phosphate 0.5%, a combination of both components and a placebo was performed on 51 ragweed sensitive patients presenting allergic conjunctivitis. Evaluation of response at various times after instillation of medication for lacrimation, conjunctival inflammation, pruritus, photophobia and pain showed naphazoline hydrochloride, antazoline phosphate and the combination product superior to placebo. The combination product was statistically significantly superior for conjunctival inflammation and photophobia. The need for post-challenge treatment with epinephrine hydrochloride was significantly less in those eyes treated with the combination product. demonstrating prophylactic efficacy.

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.

In a series of 84 various evaluable disseminated cancer patients treated with hydrazine sulfate as a result of a pharmaceutical-sponsored investigational new drug (IND) study, it was found that 59/84 or 70% of the cases improved subjectively and 14/84 or 17% improved objectively. Subjective responses included increased appetite with either weight gain or cessation of weight loss, increase in strength and improved performance status and decrease in pain. Objective responses included measurable tumor regression, disappearance of or decrease in neoplastic-associated disorders and long-term (over 1 year) 'stabilized condition'. Of the overall 59 subjective improvements 25 (42%) had no concurrent or prior (within 3 months) anticancer therapy of any type. Of the 14 objective improvements 7 (50%) had no concurrent or prior anticancer therapy. Of the remaining cases in which there was either concurrent or prior anticancer therapy, improvements occurred only after the addition of hydrazine sulfate to the treatment regimen. Duration of improvement was variable, from temporary to long-term and continuing. Side effects were mild, comprising for the most part low incidences of extremity paresthesias, nausea, pruritus and drowsiness; there was no indication of bone marrow depression.

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.

A dilute solution of procaine in glucose solution was injected by slow drip into the lumbar theca of patients to cause a differential block. Vasodilatation of the skin vessels of the lower limbs always occurred before any change in sensibility. The first changes in sensibility were inability to fell painful stimuli and warm stimuli; these two forms of sensibility were usually coextensive and occurred at the same time. When this was not so, either form of sensibility could be more extensively disturbed than the other. When warmth sensibility was removed, cold sensibility was either normal or diminished or cold stimuli caused non-thermal sensations such as non-thermal wetness or pressure. It is concluded that the nerve fibres signalling warmth are the smaller delta fibres or non-myelinated fibres or both. As two groups of investigators who recorded from the non-myelinated fibres in man found no non-myelinated fibres responding to cold, it is condluded that fibres signalling cold cover the same delta range as those signalling warmth, together with a proportion of larger delta fibres. When fibres subserving pain, warmth, and cold were blocked, tactile sensibility could be normal. It is concluded that, if there are tactile fibres in man in the smaller delta and non-myelinated ranges, their contribution to tactile sensibility is insignificant. It is also concluded that the pre-galglionic B fibres are the most susceptible of all fibres of the nerve roots to local anaesthetic agents. On two occasions, piloerection occurred when the pre-ganglionic sympathetic fibres were blocked. In two patients spontaneous itching occurred when all peripheral nerve fibres were blocked except large tactile fibres.

Haemodilution is an efficient conservative therapy of peripheral arterial occlusive disease. Already a single isovolaemic haemodilution (replacement of 500 ml blood for Haes* 0.5, 10%) increases the pain-free walking distance by 85%. These effects can be maintained by a constant therapy over six weeks and following haemodilution once or twice per month. The haematocrit values should be between 38 and 42%. The haemodilution should be done hyper- or isovolaemically. Not more than 250 ml blood and 500 ml Haes should be infused during one session in order to avoid hypovolaemia. This means an infusion of 250 ml Haes, venesection of 250 ml blood via the same access and then infusion of the remaining 250 ml. The whole procedure should not last more than one hour. Blood pressure, heart rate, lung auscultation and percussion as well as creatinine values has to be controlled during an intensive therapy. If the hydroxyethyl starch concentration exceeds 150 g per week pruritus may occur in singular cases, if the concentration exceeds 700 g per week it is observed in 50% of the cases. Provided the preventive measures are observed haemodilution is an efficient and good therapy which also increases the compliance to practice vascular exercise.

Because evidence from uncontrolled, unblinded studies suggested fewer side effects from epidural hydromorphone than from epidural morphine, we employed a randomized, blinded study design to compare the side effects of lumbar epidural morphine and hydromorphone in 55 adult, non-obstetric patients undergoing major surgical procedures. A bolus dose of epidural study drug was given at least 1 h prior to the conclusion of surgery, followed by a continuous infusion of the same drug for two postoperative days. Infusions were titrated to patient comfort. Visual analog scale (VAS) pain scores, VAS sedation scores, and subjective ratings of nausea and pruritus were assessed twice daily. The two treatments provided equivalent analgesia. Sedation scores and prevalence of nausea did not differ significantly between groups. Prevalence of pruritus, however, differed significantly on postoperative day 1, with moderate to severe pruritus reported by 44.4% of patients in the morphine group versus 11.5% in the hydromorphone group (P < .01). On post-operative day 2, reports of pruritus by patients receiving morphine remained higher than those among the hydromorphone-treated subjects, although this difference was no longer statistically significant (32% vs. 16.7%, P = .18). We conclude that lumbar epidural morphine and hydromorphone afford comparable analgesia, but the occurrence of moderate to severe pruritus on the first postoperative day is reduced by the use of hydromorphone.

Itch is a distinct sensation arising from the superficial layers of skin and mucous membranes. It is elicited by histamine and probably other endogenous chemicals that excite subpopulations of unmyelinated primary afferents and spinal neurones projecting through the anterolateral quadrant to the brain. The two popular views, which propose either that itch is signalled by a labelled line system of peripheral and central itch-specific neurones or that itch is the subliminal form of pain, both fail to explain convincingly many known features. Alternative theories emphasize central processes that extract the relevant information from afferents with broad sensitivity spectra for pruritogenic and noxious stimuli. Thus, itch presents an irritating challenge for the specificity theory of somatosensation.

In surgical nursing practice, postoperative pain is of particular concern because of its documented effect on recovery and behaviors associated with recovery. Yet, little is known about the nature of this pain, other than its intensity. In this study, a description of the nature of the postoperative pain experience was generated from analysis of patient responses to the McGill Pain Questionnaire in four nursing intervention studies. The combined sample included 246 adult cholecystectomy patients. Patient descriptions of pain on the third postoperative day suggest a circumscribed sensory experience of moderate intensity. Sensory descriptors selected reflect two levels of noxious stimulation, one at the deeper somatic level (e.g., throbbing, stabbing, cramping, pulling, and burning) and one at a more superficial level (e.g., pricking, sharp, pinching, itching, sore, and tender). Descriptors of deeper pain tended to reflect greater intensity. The overall experience was characterized by 16 descriptors, selected by more than 30% of the sample and reflecting sensory, affective, and evaluative dimensions of the pain experience. Comparison of the findings from this combined sample drawn from hospitals in the northeastern United States were remarkably similar to those reported by Taenzer in Canada. The descriptors selected support, extend, and validate the kind of "sensation information" needed in preoperative instruction used in nursing practice and for abdominal surgery and can be useful in the assessment and management of postoperative pain.
