Perianal hidradenitis suppurativa, a chronic recurrent inflammatory disease of apocrine glands, adjacent anal canal skin, and soft tissues, is characteristically ignored and misdiagnosed. A retrospective analysis of 43 patients with perianal hidradenitis suppurativa was performed; 40 patients (93 percent) were male and 3 (7 percent) were female, with a median age at presentation of 29 years. Symptoms, including pain, swelling, purulent discharge, and pruritus, had been present for a median of six years. Diagnoses at the time of presentation included pilonidal disease (28 percent), anal fistula (37 percent), and perirectal abscess (16 percent). Associated medical conditions included diabetes (12 percent) and obesity (12 percent), and 70 percent of the patients were smokers. Once the correct diagnosis was established, 72 percent of patients had wide local excision with healing by secondary intention, and 28 percent of patients had incision and drainage or limited local excision. Although 67 percent of the patients had recurrence of disease after initial treatment, wide excision was more successful in preventing recurrence. Skin grafting failed uniformly, and colostomy was rarely necessary. Despite its relatively common occurrence, perianal hidradenitis suppurativa is infrequently diagnosed correctly and recurs in many patients despite appropriate surgical treatment, making the disease a source of frustration for surgeon and patient alike.

The majority of patients with idiopathic pruritus ani respond favorably to conservative treatment. Moreover, response to specific medical therapy is almost always favorable in certain dermatologic diseases such as psoriasis, mycotic dermatitis, and contact dermatitis. When surgery is performed for anorectal disorders such as hemorrhoids and fistulas, or potentially malignant entities such as extramammary Paget's disease, the accompanying pruritus ani invariably improves as well. Only patients with chronic intractable pruritus ani are included in the current study. Methylene blue (methylthionine chloride) 0.5 percent is injected intracutaneously on the anodermal and perianal skin. With one treatment, long-term cure has been observed.

The etiology of vaginitis can be difficult to prove. To determine the relationship between clinical criteria (symptoms and signs) and three causes of vaginitis, we prospectively evaluated 22 criteria in 123 unselected symptomatic patients. Diagnoses of Candida albicans and Trichomonas vaginalis infection were based on culture. Bacterial vaginosis was defined by the presence of 3 of 4 clinical criteria. Only 49% of our patients received diagnoses, and itching was the only symptom more frequently noted among those with diagnoses. Symptoms did not differ among the three infections, and lack of vaginal odor in yeast infection was the only significantly different physical sign. Yeast and trichomonads were seen on microscopy in 63% and 75% of culture-positive specimens. Bacterial vaginosis had no significant clinical criteria beyond those that defined the diagnosis. We conclude that presenting symptoms and signs in vaginitis evaluation have limited value, and that half of the women with vaginitis may lack a microbiologic diagnosis.

Two men, aged 54 and 31 years respectively, developed an itching skin rash 18 and 6 months respectively after returning from a trip to Africa, the former also recurrent conjunctivitis. Two years and 6 months, respectively, passed from the time of first symptoms until the diagnosis of onchocerciasis was made. Both patients had an eosinophilia (10.5 and 19%) and specific antibodies against Onchocerca volvulus. Microfilaria were demonstrated in the skin of the younger man. The other one had bilateral corneal infiltrates. Both patients were treated with a single dose of ivermectin, 150 micrograms/kg. Within several months, the clinical symptoms and eosinophilia disappeared and the antibody titres decreased.

Ursodeoxycholic acid treatment of patients with primary biliary cirrhosis may lead to relief of pruritus and improvement of biochemical liver tests. The changes in serum and urinary bile acids induced by ursodeoxycholic acid treatment were studied. After 29 patients with primary biliary cirrhosis were treated with ursodeoxycholic acid (750 to 1,000 mg/day) for 6 to 12 mo because of an increase in ursodeoxycholic acid, total plasma bile acids increased from 30.5 +/- 6 mumol/L (mean +/- S.E.M.) to 52.7 +/- 11.7 mumol/L (p less than 0.01). The increase in total plasma bile acids correlated significantly with concentrations of plasma bile acid before treatment (p less than 0.01). The concentrations of endogenous bile acids decreased, mainly because of a decrease of cholic acid. During treatment, glycine conjugation increased and taurine conjugation decreased, whereas sulfation and glucuronidation of bile acids were unchanged. In 10 patients with primary biliary cirrhosis in stages III and IV, urinary excretion of bile acids was also studied. After treatment, ursodeoxycholic acid and its 3-beta isomer and C-1-hydroxylated and C-6-hydroxylated derivatives were also excreted. During treatment, urinary excretion of endogenous bile acids decreased. The increase of ursodeoxycholic acid and the decrease of endogenous bile acids may both be related to the improvement of biochemical liver tests in precirrhotic stages of the disease. In cirrhosis, endogenous bile acids in plasma remained high and changes in liver tests were small.

The long-term analgesic effects and the complications of epidural narcotic analgesia (ENA) were investigated in 40 cancer patients in whom systemic narcotic therapy failed to relieve pain or caused unacceptable side effects. In 32 patients, an externally fixated polyamide epidural catheter was used ("external group"), and in 8 patients, a polyurethane epidural catheter was tunneled and connected to a subcutaneous access port ("internal group"). The average duration of catheter treatment was 80.9 days (range 9-533 days). Twenty-five patients were treated as outpatients, and 15 remained hospitalized. Initially, all patients had significant or complete pain relief from 10 mg morphine/day, but the daily epidural morphine requirement showed a threefold increase during the first 3 weeks. During ENA, other methods of pain relief (radiotherapy, chemotherapy, surgery, epidural administration of local anesthetics, and nerve blocks) were necessary in 14 patients. Pharmacological side effects were of minor importance, with transient pruritus being the main subjective complaint. In the "external" group, 31 catheter replacements were necessary, mostly due to backflow of injected morphine outside the catheter. In two patients of the internal group, neurological complications occurred, but these disappeared spontaneously after removal of the system. They were presumably due to epidural fibrosis with compression of the spinal cord. Further technical improvements are necessary for the easier use and higher safety of the catheter technique.

The therapeutic efficacy of a lotion containing 5% benzoyl peroxide and 2% miconazole was compared with 5% benzoyl peroxide alone, in a double-blind, randomized, parallel study. Thirty patients with comedonal or inflammatory acne vulgaris were enrolled. The medications were applied once daily during the first week, and then twice daily for the rest of the trial (45 days). In patients with comedonal acne there was no difference in the effect of the two therapies. In patients with inflammatory acne the percentage reduction of the number of lesions on Day 30 was significantly higher in the benzoyl peroxide plus miconazole group (66%) compared to benzoyl peroxide alone (37%). At Day 45 there was a trend favouring the combined therapy but the difference was not significant. There were no significant differences in the adverse reactions reported by the two groups of patients (erythema, itching or moderate exfoliation).

Hydroxyzine, a potent H1-receptor antagonist often used for relief of pruritus in patients with hepatic dysfunction, was studied in eight patients, mean age 53.4 +/- SD 11.2 years, with primary biliary cirrhosis. The patients ingested a single dose of hydroxyzine, 0.7 mg/kg (mean dose 43.9 +/- 6.6 mg). Before the dose, then hourly for 6 hours, every 2 hours from 6-12 hours, at 24 hours, and every 24 hours for 6 days, serum hydroxyzine and cetirizine were measured and an intradermal injection of 0.01 mL of a 0.1 mg/mL solution of histamine phosphate was performed. Wheals and flares were traced at 10 minutes and the areas were calculated. Mean peak hydroxyzine levels of 116.5 +/- 60.6 ng/mL occurred at 2.3 +/- 0.7 hours and mean peak cetirizine levels of 500.4 +/- 302.0 ng/mL occurred at 4.8 +/- 2.8 hours. The mean serum elimination half-life of hydroxyzine was 36.6 +/- 13.1 hours, and the mean serum elimination half-life of cetirizine was 25.0 +/- 8.2 hours. The mean hydroxyzine clearance rate was 8.65 +/- 7.46 mL/min/kg, and the mean volume of distribution was 22.7 +/- 13.3 L/kg. The mean wheal area was suppressed (P less than 0.01) from 1 to 120 hours, with maximal suppression from 2 to 48 hours. The mean flare area was suppressed from 1 to 144 hours, with maximal suppression from 3 to 24 hours (P less than 0.01). All patients became sleepy from 0.5 to 6 hours. Blurred vision, dizziness and dry mouth each occurred in two patients. Hydroxyzine elimination is impaired in patients with primary biliary cirrhosis.(ABSTRACT TRUNCATED AT 250 WORDS)

The objective of these three double-blind multi-centre studies was to determine whether terfenadine 120 mg once daily has similar efficacy and tolerability as the standard dosage of 60 mg twice daily in the treatment of chronic urticaria. A total of 252 patients were randomly allocated to two parallel groups and treated for 2 weeks with either regimen. Evaluation of efficacy was based on rating scales for investigator and patient, i.e. itch, number of wheals, wheal size and an overall rating of efficacy. A similar improvement was seen in all variables, and there were no statistically significant differences between treatment groups. The power of the studies combined is greater than 80%, i.e. sufficient to state convincingly that treatment effects are not different. Both treatments were also equally well tolerated.

Recently several reports have described the usefulness of meperidine as the sole agent for spinal anesthesia. In this study, meperidine 50mg mixed with 10% dextrose 0.5ml was used for the spinal anesthetic agent for Cesarean section in 182 cases. The subarachnoid injection of meperidine resulted in anesthesia similar to that noted with the intrathecal administration of local anesthetics. Sensory and motor blockades in all patients with meperidine spinal anesthesia were obtained. Prolonged analgesic effect (453.7 +/- 158.1 minutes) and rapid motor recovery (75.9 +/- 17.2 minutes) were obtained. Side effects included nausea (49 patients), hypotension (95 patients) and pruritus (30 patients). Hypotension was easily treated with rapid hydration and ephedrine. Eighteen patients complained of mild pain during the last period of operation. At birth, all newborns cried immediately and the mean Apgar scores were 9.8 +/- 0.4 at one minute and 10 at 5 minutes. It is concluded that meperidine, which has advantages such as rapid motor recovery, prolonged postoperative analgesia, and mild complications which may be easily treated, can serve as a good alternative agent for spinal anesthesia for Cesarean section.
