An adult domestic short-hair cat from south Texas was examined because of excessive dandruff on the back, neck, thorax, and hind limbs. Removal of a few hairs for microscopic evaluation revealed Lynxacarus radovskyi, the cat fur mite. The small (< 0.5 mm) mite could be readily identified by its laterally compressed body and its characteristic grasping of the hair shaft between the gnathosoma and palpi. Thus far, this mite has been identified as a parasite of cats in warm, humid environments. The number of parasites and apparent discomfort in cats varies considerably, from massive infestation with little discomfort to few mites and marked pruritus. Acaricides that are effective against other ectoparasites of cats apparently are effective in controlling L. radovskyi.

A silicone vaginal ring releasing 5-10 micrograms oestradiol/24 h for a minimum of 90 days has been developed for treatment of urogenital mucosal atrophy. The efficacy, safety and acceptability of the oestradiol-releasing ring were studied in 222 postmenopausal women with symptoms and signs of atrophic vaginal mucosa. The maturation of the vaginal epithelium, as measured by cytological parameters, was significantly improved during treatment. No proliferation of the endometrium was encountered. The therapy had a significant effect on symptoms (vaginal dryness, pruritus vulvae, dyspareunia, urinary urgency) and on signs of atrophic vaginitis, with cure/improvement registered in > or = 90%. The patient acceptability was high, since > or = 90% did not report any discomfort with the ring. Almost all of the sexually active women had the ring in place during coitus and in < or = 2% of cases discomfort was noticed by them or the partner. It is concluded that a vaginal silicone ring giving a continuous release of an ultra-low dose of oestradiol is an effective and safe treatment for urogenital oestrogen deficiency. No addition of progestagen is needed.

This was an open, randomized, cross-over study comparing the efficacy and acceptability of aqueous nasal suspensions of budesonide, 200 micrograms b.i.d. and beclomethasone dipropionate (BDP), 100 micrograms q.i.d., each given for 6 weeks to patients with perennial rhinitis and a history of allergy. Forty men and women aged 18-65 years with perennial rhinitis diagnosed at least 1 year previously, were recruited for study provided they had at least two of the following symptoms of rhinitis--blocked nose, runny nose, itching nose or sneezing. They were requested to record the presence or absence of nasal and ocular symptoms on a severity scale of 0-3 (none, mild, moderate, severe) in daily diary cards. The sum of the nasal scores was calculated to give the total nasal symptom score. Mean individual symptom scores and total symptom score were calculated for each treatment. Thirty-seven patients completed the study. The mean total nasal symptom score was significantly lower during budesonide (2.13) than during BDP (2.75), P = 0.001. There were significantly fewer reports of blocked nose (P = 0.004), runny nose (P = 0.0005) and sore eyes (P = 0.047) during budesonide treatment compared with BDP. Four patients reported adverse events during budesonide treatment (two had nosebleeds and two nasal dryness) and three patients during BDP treatment (two had nasal dryness and one gastric discomfort). A significantly greater proportion of patients stated a preference for budesonide than for BDP on the basis of effect (P = 0.0001), side-effects (P = 0.01), and overall (P = 0.0001).

Fosphenytoin is a water-soluble disodium phosphate ester of phenytoin that is converted in plasma to phenytoin. Fosphenytoin is compatible with most common i.v. solutions and can be administered safely through the i.m.route. An additional safety factor is the absence of propylene glycol in the fosphenytoin formulation. Propylene glycol is used as a vehicle in the i.v. phenytoin preparation and by itself may produce serious cardiovascular complications. Studies of the pharmacokinetics, safety, and tolerance of i.v. fosphenytoin have demonstrated that fosphenytoin produces phenytoin plasma concentrations similar to those achieved with oral and i.v. phenytoin, but without significant cardiovascular effects and only minimal discomfort at the injection site. Aside from local reactions, the most common adverse events associated with fosphenytoin have been pruritus and reactions typical of phenytoin (e.g., dizziness, somnolence, and ataxia). Fosphenytoin represents a significant advance in the treatment of patients with seizures who require parenteral therapy.

The authors are describing their own clinical experience with the treatment of vaginal candidosis with the application of a single dose clotrimazole 500 (Canesten 1) with only one vaginal globule. In 81% of the cases is obtained a perfect result with disappearing of the clinical symptoms (pruritus, bleeding, discomfort during excretion of urine) and negativisation of the microbiological results. In 9% the esteemed clinical result is not obtained. The authors are making the conclusion, that the treatment with a unique vaginal globule can be useful in light and acute cases of mycotic colpitis in non-pregnant as well as in pregnant women. A recommendation is given for follow-up of the pregnant patients in the last 3-4 weeks of the pregnancy, for a candidosis check-up and for prescription of an adequate treatment.

Haemorrhoids or piles are varicosities in the anal canal caused by local pressure. Sometimes they prolapse. Symptoms may include itching, discomfort, pain and bleeding. Haemorrhoids are common in pregnancy. Constipation aggravates piles, so a healthy diet with plenty of water and fibre is advisable. Some sufferers need an appropriate laxative as well. Cleanliness of the anal area is important. Proprietary moist toilet tissues are sold for this purpose and can be soothing and helpful. Relief of symptoms is by haemorrhoid creams, ointments and suppositories. Active ingredients typically include antiseptics, anti-inflammatories, anti-pruritics and local anaesthetics. Many are available from pharmacies without a prescription. If in doubt, always refer the patient to a doctor. For example, rectal bleeding may be due to some more serious condition, or pruritus to anal thrush. In the case of children the advice of a doctor should be sought.

Pruritus may cause severe chronic discomfort to PV patients. Most of the usual treatments are not at all or only weakly efficient. Photochemotherapy using psoralen and ultraviolet A light may largely improve the clinical symptom of intractable itching, as observed in ten of the 11 cases presented, but maintenance therapy is generally necessary. The treatment may then improve the patient's quality of life.

A two-centre, double-blind, randomized, placebo (P)-controlled, parallel-group study was conducted in the UK to examine the efficacy and safety of mizolastine (M), a new H1-receptor antagonist, as a once-daily 10-mg dose in chronic idiopathic urticaria. Fifty-six outpatients (M: n = 28; P: n = 28) with a mean age of 38 +/- 15 years, a duration of disease of more than 3 years, and symptoms of urticaria at least twice a week in the absence of treatment were recruited. After a single-blind placebo run-in period, patients were allocated to one of two treatment groups and were evaluated after 7 and 28 days. The main characteristics (age, duration of disease, number of urticarial episodes, and total score) of the two groups were comparable at inclusion. Mizolastine was shown to improve the urticaria symptoms: at the end of the study, mizolastine produced a significantly greater decrease in the global symptom score comprising itch, wheals, and erythema (M: 2.1 +/- 2.1 vs P: 0.4 +/- 2.0; P = 0.002). The patient-rated global discomfort from symptoms measured by visual analog scale was significantly improved with mizolastine (M: 31.4 +/- 36.7) compared to placebo (P: 5.4 +/- 27.6; P = 0.003), with respectively more M responders (74.1%) than P responders (28.6%, P = 0.001), a responder being a patient with a > or = 50% decrease in VAS. Premature dropouts due to lack of efficacy and loss to follow-up mainly occurred at the first evaluation (day 7) and were more often observed in patients in the placebo group (n = 17) than in the mizolastine group (n = 8) (P = 0.031). No serious adverse events were recorded. Somnolence was reported in two mizolastine patients, one of whom discontinued the study. Thus, mizolastine may be considered a new treatment option for the symptoms of chronic urticaria.

We performed a double-blind, controlled trial to determine the optimal dose of intrathecal fentanyl in small-dose hypobaric lidocaine spinal anesthesia for outpatient laparoscopy. Sixty-four gynecological patients were randomized into three groups, receiving 0, 10, or 25 micrograms fentanyl added to 20 mg lidocaine and sterile water (total 3 mL). Administration was with 27-gauge Whitacre needles and patients sat upright until the block was > T-8. One patient in the 0-microgram fentanyl group required general anesthesia 40 min after the start of surgery, leaving 21 patients per group. Three patients in each of the 0-microgram and 10-microgram fentanyl groups had mild discomfort with trocar insertion, or return of some sensation and felt discomfort or sutures toward the end of surgery. Shoulder-tip pain was less frequent in the 25-microgram than 0-microgram fentanyl group, 28% vs 67% (P < 0.0166). Intraoperative supplementation with alfentanil (+/- propofol) was needed less often in the 25-microgram than 0-microgram fentanyl group, 43% vs 76% (P = 0.028). Recovery of sensation took longer in the 25-microgram than in the 0-microgram and 10-microgram fentanyl groups, 101 +/- 21 vs 84 +/- 20 and 87 +/- 18 min (P < 0.05), although motor recovery and discharge times were the same. Postoperative analgesia was needed earlier in the 0-microgram than in the 25-microgram fentanyl group, median 54 (13-120) vs 87 (65-132) min (P < 0.05). Pruritus was the only side effect that occurred more often in the 10-microgram and 25-microgram groups than in the 0-microgram fentanyl group, 62% and 67% vs 14% (P < 0.0166). One patient required an epidural blood patch for postdural puncture headache. Based on these results, we concluded that 25 micrograms intrathecal fentanyl is required when 20 mg lidocaine is used for hypobaric spinal anesthesia (SA) to ensure reliable, durable anesthesia, reduce shoulder-tip pain, and minimize the need for intraoperative supplementation. This dose provides longer postoperative analgesia and does not increase side effects apart from pruritus. SA with small-dose hypobaric lidocaine-fentanyl was found to be a satisfactory technique for outpatient laparoscopy, although postdural puncture headache can occur in some patients.

Remifentanil hydrochloride is a new, ultrashort-acting opioid metabolized by nonspecific plasma and tissue esterases. We conducted this multicenter study to examine the hemodynamic response and recovery profile of premedicated children undergoing strabismus repair who were randomly assigned to receive one of four treatment drugs (remifentanil, alfentanil, isoflurane, or propofol) along with nitrous oxide and oxygen for maintenance of anesthesia. Induction of anesthesia was by nitrous oxide, oxygen, and halothane or nitrous oxide, oxygen, and propofol. Anesthesia was then maintained with remifentanil 1.0 microgram/kg over 30-60 s, followed by a constant infusion of 1.0 microgram.kg-1.min-1, alfentanil 100 micrograms/kg bolus followed by a constant infusion of 2.5 micrograms.kg-1.min-1, propofol 2.5 mg/kg bolus followed by a constant infusion of 200 micrograms.kg-1.min-1, or isoflurane 1.0 minimum alveolar anesthetic concentration. The infusions of the anesthetics and the administration of the inhaled gases were adjusted clinically by predetermined protocols. Elapsed time intervals from the end of surgery to the time the patients were tracheally extubated and displayed purposeful movement, as well as the time the patients met the postanesthesia care unit (PACU) and hospital discharge times, were recorded. Heart rate and systolic and diastolic blood pressure were measured at fixed intervals. In addition, cardiovascular side effects (bradycardia, hypotension, and hypertension) as well as vomiting, pruritus, agitation, and postoperative hypoxemia were also noted. There were no significant differences in patient demographics among the treatment groups. There was no difference in the early recovery variables (times to extubation and purposeful movement) or the times to PACU and hospital discharge among groups. There were significant differences in side effects among the groups. Patients who received remifentanil had higher PACU objective pain-discomfort scores than those who received alfentanil and propofol. Patients anesthetized with alfentanil had a greater incidence in the use of naloxone and a greater incidence of postoperative hypoxemia compared with those anesthetized with remifentanil. The incidence of postoperative hypoxemia was the same for remifentanil, propofol, and isoflurane groups. There were no significant differences in the incidence of emesis among the four groups, and all four groups had similar hemodynamic profiles. We conclude that remifentanil appears to be an effective drug for anesthesia. Its hemodynamic and recovery profile appear similar to other comparable drugs. Based on previous pharmacokinetic studies, the 1.0 microgram.kg-1.min-1 infusion may be twice the 50% effective dose observed in adults. In this study, the relative "overdose" of remifentanil was well tolerated and did not prolong recovery.
