Abstract
To evaluate the incidence of disseminated Mycobacterium avium complex infection (DMAC) and to define the association between signs and symptoms and development of DMAC in patients with human immunodeficiency virus (HIV) infection, all cases of DMAC at Grady Memorial Hospital Infectious Disease Clinic (Atlanta) between 1985 and 1990 were reviewed, and a prospective study of the association of symptoms with DMAC was done. Between 1985 and 1990, DMAC occurred in 16% of patients with AIDS. Incidence increased from 5.7% in 1985-1988 to 23.3% in 1989-1990 (P less than .001). Median time from AIDS diagnosis to diagnosis of DMAC increased from 4.5 months in 1985-1988 to 8 months in 1989-1990 (P less than .02). In the prospective study, DMAC was seen only in persons with a CD4+ count less than 100 cells/mm3 and was associated with fever (P less than .03), anemia (P less than .001), weight loss (P less than .01), diarrhea (P less than .01), and elevated alkaline phosphatase (P less than .01). It is recommended that all such HIV-infected persons have mycobacterial blood cultures done.

Abstract
BACKGROUND Intravenous amphotericin B, with or without flucytosine, is usually standard therapy for cryptococcal meningitis in patients with the acquired immunodeficiency syndrome (AIDS). Fluconazole, an oral triazole agent, represents a promising new approach to the treatment of cryptococcal disease. METHODS In a randomized multicenter trial, we compared intravenous amphotericin B with oral fluconazole as primary therapy for AIDS-associated acute cryptococcal meningitis. Eligible patients, in all of whom the diagnosis had been confirmed by culture, were randomly assigned in a 2:1 ratio to receive either fluconazole (200 mg per day) or amphotericin B. Treatment was considered successful if the patient had had two consecutive negative cerebrospinal fluid cultures by the end of the 10-week treatment period. RESULTS Of the 194 eligible patients, 131 received fluconazole and 63 received amphotericin B (mean daily dose, 0.4 mg per kilogram of body weight in patients with successful treatment and 0.5 mg per kilogram in patients with treatment failure; P = 0.34). Treatment was successful in 25 of the 63 amphotericin B recipients (40 percent; 95 percent confidence interval, 26 percent to 53 percent) and in 44 of the 131 fluconazole recipients (34 percent; 95 percent confidence interval, 25 percent to 42 percent) (P = 0.40). There was no significant difference between the groups in overall mortality due to cryptococcosis (amphotericin vs. fluconazole, 9 of 63 [14 percent] vs. 24 of 131 [18 percent]; P = 0.48); however, mortality during the first two weeks of therapy was higher in the fluconazole group (15 percent vs. 8 percent; P = 0.25). The median length of time to the first negative cerebrospinal fluid culture was 42 days (95 percent confidence interval, 28 to 71) in the amphotericin B group and 64 days (95 percent confidence interval, 53 to 67) in the fluconazole group (P = 0.25). Multivariate analyses identified abnormal mental status (lethargy, somnolence, or obtundation) as the most important predictive factor of a high risk of death during therapy (P less than 0.0001). CONCLUSIONS Fluconazole is an effective alternative to amphotericin B as primary treatment of cryptococcal meningitis in patients with AIDS. Single-drug therapy with either drug is most effective in patients who are at low risk for treatment failure. The optimal therapy for patients at high risk remains to be determined.

Abstract
The Infectious Diseases Clinic (IDC) discussed serves adults who are seropositive for human immunodeficiency virus. The authors reviewed the outpatient and inpatient microbiology tests of a three-month period during 1989 for a systematic sample of IDC patients. The 249 patients in the sample had 682 microbiology tests performed during the period (mean 2.7 tests per patient). Tests most frequently requested were mycobacterial culture, routine blood culture, and cryptococcal antigen determination. Patients with acquired immunodeficiency syndrome (43% of IDC patients) accounted for 63% of the requested IDC tests. IDC patients comprised about 2.4% of patients served but accounted for 3.9% of the requested microbiology tests and 6.6% of the microbiology work load for reported tests. Using Centers for Disease Control case projections, the authors estimated that services to IDC patients in 1993 would comprise 6.6% of all microbiology tests and 10.6% of the microbiology work load. The implications of these data for microbiology probably also apply to other laboratory testing and emphasize the need for more efficient ways to use and perform diagnostic studies required by patients with HIV infection.

Abstract
The contribution of disseminated Mycobacterium avium complex (DMAC) infection to the morbidity and mortality of patients with acquired immune deficiency syndrome (AIDS) is unclear. Previous studies that suggested the decreased survival of patients with AIDS and DMAC had incomplete information on patient immunologic status and follow-up. We studied patients with AIDS and DMAC and compared their survival with that of AIDS patients without DMAC but with other comparable risk factors for survival. Case and control subjects were similar in terms of CD4 cell count, prior AIDS status, history of antiretroviral therapy, history of Pneumocystis carinii prophylaxis, and year of diagnosis. A group of 39 patients with untreated DMAC had significantly shorter survival, mean of 5.6 +/- 1.1 months (median 4 months), than 39 matched patients with AIDS but without DMAC, mean 10.8 +/- 1.3 months (median 11 months, p less than 0.0001). The survival of 16 additional patients with DMAC who received antimycobacterial therapy, mean of 9.5 +/- 1.4 months (median 8 months), was not significantly shorter than that of an additional 16 matched control subjects, mean 11.7 +/- 1.9 months (median 11 months, p = 0.58). Patients with treated DMAC survived significantly longer than those with untreated DMAC (p less than 0.01). We conclude that untreated DMAC significantly shortens survival. Moreover, these results indicate that patients with DMAC who receive antimycobacterial therapy do not experience the shortened survival seen in untreated DMAC.

Abstract
Three postoperative analgesic protocols were assigned randomly to 24 healthy dogs after thoracotomy at the left fourth intercostal space. Morphine was administered parenterally to eight dogs after tracheal extubation; selective intercostal nerve blocks with bupivacaine hydrochloride and epinephrine were administered to eight dogs before closure of the thorax; and bupivacaine hydrochloride and epinephrine were administered through an interpleural catheter to eight dogs after tracheal extubation. Heart rate, respiratory rate, rectal temperature, hematocrit, plasma protein, blood gas, and pain score evaluations were recorded before surgery and 30 minutes, 1 hour, 2 hours, and 3 hours after extubation. Morphine caused significant decreases in blood pH and blood oxygen tensions, and significant increases in carbon dioxide tensions. Dogs treated with intercostal nerve blocks had no significant changes in these parameters, and dogs treated with interpleural bupivacaine had significant decreases in blood oxygen tension. All dogs had significant decreases in rectal temperature, and hypothermia was prolonged after morphine. Analgesia was initially adequate in most dogs, but some dogs in each treatment group had recurrence of pain and were treated with interpleural bupivacaine. One dog developed pneumothorax. Interpleural administration of bupivacaine produced analgesia equal to that produced by systemic administration of morphine or selective intercostal nerve block with bupivacaine. Bupivacaine was easily readministered through an interpleural catheter. Respiratory compromise was less in dogs treated with bupivacaine than in dogs treated with morphine. After intercostal thoracotomy, interpleural bupivacaine provided prolonged analgesia with fewer blood gas alterations than morphine.

Abstract
Serial recordings of sensory evoked potentials (SEP) generated in response to stimulation of each tibial nerve were obtained from 23 anesthetized dogs. Five dogs were anesthetized for 3 hours to evaluate changes in serial SEP during general anesthesia. Nonsurgical and surgical manipulations were performed on one hind limb of five dogs to determine the effects of limb positioning and nerve retraction on SEP. In 13 dogs, the ischiatic nerve was exposed surgically and retracted until the SEP deteriorated and disappeared, to determine the relationship between amount of tension on the nerve and the time to complete deterioration of the SEP. Sensory evoked potential waveforms, which consisted of two to five peaks, were stable throughout the anesthetic period. The first two peaks were the most stable. Latency of the first two peaks was the easiest and most reliable parameter to evaluate. Although the peak latency in recordings from the superior hind limb was always slightly longer, SEP recordings from the inferior limb were good controls to monitor nerve function. There was considerable variation in sensitivity to nerve retraction. The technique proved to be a reliable way to monitor nerve function in normal anesthetized dogs.

Abstract
Urinary tract infections are a common problem in female patients. Twenty-five per cent of patients with an initial infection will develop recurrent infections, with reinfection of the urine some time after the urine has been sterilized being the most common situation. Most adult patients have no urinary tract abnormality, with the infecting organism coming from the rectum and colonizing the vagina before colonizing the bladder. In children with urinary tract infections, there is a higher incidence of urinary tract abnormalities. The author presents a plan of management for various clinical problems.

Abstract
A multivariate logistic regression analysis of patient symptoms and signs and laboratory findings associated with the diagnosis of acute pelvic inflammatory disease was performed with use of data from 628 women who were clinically diagnosed as having the disease for the first time at the University of Lund, Sweden. In 414 women (65.9%) acute pelvic inflammatory disease was laparoscopically confirmed. We developed a mathematical model that correctly predicted 87.0% of the cases of acute pelvic inflammatory disease and had an overall correct classification rate of 75.6%. Variables that were good predictors of acute pelvic inflammatory disease were purulent vaginal discharge, erythrocyte sedimentation rate greater than or equal to 15 mm/hr, positive gonorrhea result, adnexal swelling on bimanual examination, and rectal temperature greater than or equal to 38 degrees C. Furthermore, we developed "mixed model I" and "mixed model II," which combine simple clinical parameters and laparoscopy in varying degrees. In mixed model I the sensitivity, specificity, and overall classification values were 93%, 67.2%, and 84.5%; in mixed model II these values were 100%, 67.2%, and 89.2%. Use of relatively simple and reproducible clinical parameters can identify those women who would most benefit from laparoscopy to diagnose acute pelvic inflammatory disease.

Abstract
To study the duration of antibody persistence and protection provided by the hepatitis B vaccine, we followed 773 homosexual men for five years after completion of vaccination. Among the 635 participants in whom antibody levels above 9.9 sample ratio units (SRU) developed after vaccination, 15 percent lost antibody altogether, and in another 27 percent, antibody levels declined below 10 SRU within five years. The extent of the maximal antibody response strongly predicted the persistence of protective antibody. Hepatitis B infection occurred in 55 men; 8 of these infections were clinically important (characterized by the presence of the hepatitis B surface antigen and elevation of liver-enzyme levels), and two of the patients became hepatitis B virus carriers. The long-term risk of hepatitis B infection was inversely related to the maximal antibody response to vaccine. Most severe infections occurred among those who responded poorly or had no response to the vaccination. The risk of late infection with hepatitis B in those with an initially adequate vaccine response increased markedly when antibody levels decreased below 10 SRU, but only 1 of 34 late infections resulted in viremia and liver inflammation. A second series of vaccinations induced a moderate antibody response in 50 percent of the subjects who initially had no response or a poor response; however, the persistence of antibody was poor. Both antibody loss and the risk of severe disease should be considered when booster-dose strategies for the hepatitis B vaccine are being designed.

Abstract
Eight hundred twenty-five ambulatory women with a clinical diagnosis of salpingitis were randomized to a 10-day course of either penicillin/ampicillin or tetracycline. Forty-four percent of women had gonococcal salpingitis and 56% nongonococcal salpingitis. Overall, both regimens cured equal proportions of women: At 30 days, 81% were cured by penicillin/ampicillin and 82% by tetracycline. However, the proportion of women with gonococcal salpingitis cured by 30 days was significantly greater than that of women with nongonococcal salpingitis. By 30 days, 14% of women with gonococcal salpingitis and 21% of women with nongonococcal salpingitis were not cured by either regimen. These data suggest that both regimens were only marginally acceptable for women with gonococcal salpingitis and that neither regimen was acceptable for nongonococcal salpingitis.

Abstract
A total of 149 sera, including 79 pre- and posttreatment sera from 33 patients with disseminated gonococcal infections, 18 from patients with uncomplicated gonococcal infections, 6 from patients with pelvic inflammatory disease, 4 from patients with genital Chlamydia trachomatis infections, and 42 from normal volunteers, were examined for C-reactive protein with a latex agglutination C-reactive protein detection kit (Difco Laboratories, Detroit, Mich.). Results were quantitated with LC-Partigen C-reactive protein radial immuno-diffusion plates (Calbiochem-Behring, La Jolla, Calif.). Positive latex agglutination results were observed in all of the pretreatment sera and some of the posttreatment sera of patients with disseminated gonococcal infections and in two sera from patients with pelvic inflammatory disease, which corresponded to quantitative C-reactive protein levels in the radial immunodiffusion plates. C-reactive protein levels were not detectable in the serum samples from normal volunteers or patients with uncomplicated gonococcal infections or genital chlamydial infections. Positive latex agglutination occurred as early as 20 s in sera with high C-reactive protein levels, and all positive results were observed within 90 s of the 3-min test limit. Positive latex test results were obtained with C-reactive protein levels as low as 1 mg/dl (10 micrograms/ml).

Abstract
Gonococci can be divided into serogroups WI, WII, and WIII by coagglutination. To assess the clinical correlation of serogroups of gonococci, we studied isolates of gonococci from patients with disseminated and uncomplicated gonococcal infections in three cities in the United States. Strains of Neisseria gonorrhoeae belonging to serogroup WI represented 85 (84%) of 101 isolates from patients with disseminated gonococcal infection (DGI) and 68 (40%) of 168 isolates from patients with uncomplicated gonorrhea (P less than .001). The auxotype Arg-, Hyx-, Ura- (AHU) represented 62 (61%) of 101 isolates from DGI and 54 (32%) of 168 isolates from uncomplicated infection (p less than .001); all AHU isolates were serogroup WI. Among other auxotypes, WI strains represented 25 (64%) of 39 isolates from patients with DGI and 14 (12%) of 114 from uncomplicated infections (P less than .001). In Atlanta only, 13 (34%) of 38 isolates from DGI were AHU, but 31 (82%) were serogroup WI (P less than .001). Thus gonococci of serogroup WI are associated with DGI in these cities of the United States, and this correlation appears to be independent of auxotype. Serogroup WI is correlated with serum resistance.

Abstract
In a randomized double-blind trial, 216 men and 142 women infected with uncomplicated gonorrhea were treated with either 1.5 g of cefuroxime or 4.8 x 10(6) U of aqueous procaine penicillin G intramuscularly and 1.0 g of probenecid. The cure rates in the treatment groups were 96 and 95%, respectively. Intramuscularly administered cefuroxime was better tolerated than was procaine penicillin. Comparative antibiotic susceptibility studies revealed that cefuroxime and penicillin were about equally active and that both were more active than cefamandole or cefoxitin. Because cefuroxime is not degraded by the action of beta-lactamase enzymes, it has promise as an alternative to spectinomycin in the treatment of penicillinase-producing Neisseria gonorrhoeae infections.

Abstract
A randomized, double-blind, vaccine/placebo trial of the Merck 20-micrograms hepatitis B virus (HBV) vaccine was done among 1402 homosexual men attending venereal disease clinics in five American cities. Vaccination was followed by only minimal side effects. Two doses of vaccine induced antibody in 80% of vaccine recipients. A booster dose 6 months after the first dose induced antibody in 85% of recipients and markedly increased the proportion of recipients who produced high antibody titers. The incidence of HBV events was markedly less in the vaccine recipients compared to that in the placebo recipients (p = 0.0004). Between month 3 and 15 after the first dose, 56 more significant HBV events (hepatitis, or hepatitis B surface antigen positive, or both) occurred in the placebo group while only 11 occurred in the vaccine group. Ten of the 11 HBV events in the vaccine recipients occurred in hypo- or nonresponders to the vaccine. This vaccine appears to be safe, immunogenic, and efficacious in preventing infection with hepatitis B virus.

Abstract
Of 3,816 homosexual men examined in five sexually transmitted disease clinics in the United States, 6.1% had hepatitis B surface antigen, 52.4% had antibody to hepatitis B surface antigen, and 3.0% of the men who had no other indicator of infection with hepatitis B virus (HBV) had antibody to hepatitis B core antigen. The rate of seropositivity for HBV indicated by the presence of one or more of these serologic markers was 61.5%; seropositivity was significantly related to the duration of regular homosexual activity and to the number of nonsteady male sexual contacts in the four months before the patients were interviewed. Anal-genital intercourse, oral-anal intercourse, and rectal douching were significantly related to evidence of HBV infection, but oral-oral contact and oral-genital contact were not. Trauma to the rectal mucosa is a feature common to the practices that were significantly related to seropositivity for HBV.

The efficacy of trimethoprim-sulfamethoxazole (TMP-SMZ; 80 mg of TMP and 400 mg of SMZ per tablet; nine tablets taken once daily for three days; total, 27 tablets) was compared with the U.S. Public Health Service recommended regimen of 2 g of tetracycline daily for five days for the treatment of uncomplicated genital gonorrhea. Fourteen (3%) of the 461 patients treated with tetracycline and 24 (5%) of the 477 patients treated with TMP-SMZ failed to be cured; the difference between the two groups was not significant. Treatment of patients with TMP-SMZ was more likely to fail if the isolates of Neisseria gonorrhoeae had MICs of > or = 0.5 microgram of TMP/ml and > or = 9.5 micrograms of SMZ/ml. Adverse effects were more often reported by patients receiving TMP-SMZ. The results show that TMP-SMZ is an effective therapy for uncomplicated gonococcal infections in men and women and may also eliminate agents causing postgonococcal urethritis. The utility of this drug combination may be limited by the adverse effects that are associated with the large dose used.

Abstract
Of an unselected group of 159 women attending a sexually transmitted diseases (STD) clinic 20% (32) had symptoms of urethritis. A positive correlation existed between the finding of more than 10 polymorphonuclear leucocytes (PMNL) per high-power field in the Gram-stained urethral smear and the presence of Neisseria gonorrhoeae, Chlamydia trachomatis, and Trichomonas vaginalis. Conversely, these organisms were rarely isolated if no PMNL were present. Fewer cultures gave positive results for these organisms if micturition had occurred less than four hours before examination. C trachomatis was recovered from the urethra or endocervix in 29/150 (19 . 3%) and from the urethra alone in six women. In contrast, N gonorrhoea was never recovered from the urethra in the absence of endocervical infection. Of the 159 women 10% had bacteriuria due to non-sexually transmissible agents; 50% had asymptomatic bacteriuria. All, however, had other urethral pathogens isolated as well. Thus, sexually transmitted disease agents are highly prevalent in women attending an STD clinic who have signs and symptoms of urethritis. As in non-gonococcal urethritis in men, C trachomatis may be an important cause of urethritis in women.

Abstract
Twenty-three patients with disseminated gonococcal infections--15 with acute tenosynovitis, six with septic monoarticular arthritis, and two with both--were randomly given five days of erythromycin stearate or estolate, 500 mg orally every six hours (13 patients), or crystalline aqueous penicillin G potassium, 1 million units intravenously every three hours for three days (ten patients). There were no treatment failures. Cultures taken one and seven days and two and four weeks after completion of therapy were uniformly negative. Clinical resolution was rapid in both groups, as judged by response of fever, joint tenderness, and disappearance of joint effusion. Orally administered erythromycin is a useful alternative to penicillin in the treatment of disseminated gonococcal infections, particularly in penicillin-allergic pregnant women.
