Anaesthesia for children with junctional epidermolysis bullosa (letalis).

The anaesthetic management of two children with junctional epidermolysis bullosa, formerly called the letalis form, is described. Anaesthesia for children with this disease has not been described previously. Special precautions were taken to avoid mucosal injury and some customary monitoring devices were omitted. The previous anaesthetic literature, which discusses related but distinct forms of bullous skin diseases, is reviewed. The special concerns which relate to airway management in this disease are discussed.

Effect of changing needle disposal systems on needle puncture injuries.

Accidental needle puncture injuries continue to pose a hazard to hospital workers. In order to reduce the number of such injuries in our hospital, needle disposal procedures were revised to discourage recapping and prevent bending or clipping of needles before discard. Collapsible cardboard boxes were replaced with impervious containers. An educational program accompanied these changes. We compared reports of needlestick injuries before and after the change of procedure, for three parallel 9-month periods. During the 27-month study, injuries occurred during administration of medication (22%), or recapping of used needles (16%), from needles protruding through (10%) or out of the "mouth" (9%) of the container, from needles left in the patient's environment (10%), or those left on procedure trays (7%). Seven percent were the result of being stuck by someone else, usually in the operating room. The mechanism of injury for 19% was not described. Altering the disposal procedures did not change the number or anatomic site of injuries, nor the risk of injury among the various job categories. A reduction in the rate of sticks from needles protruding through the container (1.3 vs 0.3/mo, p less than or equal to 0.005) was the only difference observed. Changing the needle receptacle changed the type but not the overall number of injuries. The education program had little effect on the number and types of injuries. These data point to the need for developing innovative approaches for eliciting changes in behavior of health care personnel.

Risk for the acquired immunodeficiency syndrome among thrombocytopenic and nonthrombocytopenic homosexual men seropositive for the human immunodeficiency virus.

A group of 44 homosexual patients with immune thrombocytopenia and serologic evidence of infection with the human immunodeficiency virus (HIV) was observed for a total of 844 person-months. The risk of developing the acquired immunodeficiency syndrome (AIDS), an actuarial incidence of 36.5% in 37 months, was no different than that reported for seropositive homosexual men from New York who are nonthrombocytopenic and asymptomatic. A statistical analysis comparing the hazard function with a constant-risk model showed that the hazard of developing AIDS was not constant but increased with duration of seropositivity.

Hospital experience with varicella-zoster virus.

Varicella-zoster virus (VZV), one of the most common highly communicable agents of disease, stimulates aggressive infection control measures. In a 1-year period, at one hospital, at least 93 inpatients (82 adult patients, 11 pediatric patients) and 2 hospital staff with active varicella-zoster infections served as potential sources of nosocomial infection. Six incidents of exposure to the virus that occurred without the protection of standard infection control precautions were investigated by the infection control surveillance team. One hundred fifty-six patients and 353 hospital staff were exposed. Fifty-one patients had no history of varicella-zoster infection, but only five were susceptible by serologic testing. One hundred one staff members had no history of varicella-zoster, but only 11 were susceptible by serologic testing. These exposures resulted in three secondary varicella-zoster infections, six courses of varicella-zoster immune globulin prophylaxis and furlough of 13 staff members. Epidemiologic investigation consumed approximately 356 hours of staff time, and management of exposed persons cost approximately $41,500. Prospective knowledge of the immune status of health care workers would vastly decrease the time and effort required to control hospital VZV exposures.

Tuberculosis in non-Haitian patients with acquired immunodeficiency syndrome.

From Jan 1, 1981 to Oct 31, 1984, 24 of 280 (8.6 percent) patients with acquired immunodeficiency syndrome (AIDS) had tuberculosis. No patient with both AIDS and tuberculosis was Haitian. In 15 patients, tuberculosis was diagnosed prior to or concomitant with the diagnosis of AIDS. Twelve patients (50 percent) had Mycobacterium tuberculosis grown from at least one extrapulmonary site. Although the clinical presentation was variable, no patient had cavitary and only one had apical disease. Histologic examination of lung and transbronchial biopsy specimens usually did not reveal acid-fast bacilli or granulomas. Seventeen patients were treated and all showed clinical improvement. Tuberculosis was infrequent but not rare in our patients and often preceded the diagnosis of AIDS. Despite the fact that many of these patients had both severe and extrapulmonary disease, they appeared to respond well to treatment.

Cryptococcal disease in patients with the acquired immunodeficiency syndrome. Diagnostic features and outcome of treatment.

Between 1 January 1981 and 1 December 1984, 34 of 396 patients with the acquired immunodeficiency syndrome (AIDS) developed cryptococcal infections. Twenty-six cases are reviewed. Twenty-two patients had brain or meningeal disease; the others had pulmonary disease (2 patients), pericarditis (1 patient), and antigenemia (1 patient). During treatment, 3 patients died of cryptococcosis and 3 died of other causes. Fifteen patients were followed for more than 6 weeks after treatment. Of 8 patients who received no additional amphotericin B, 4 had relapses and died of cryptococcosis within 6 months, 3 died of other causes, and 1 survived. Of 7 patients who received maintenance therapy with amphotericin B, none had relapses, 3 died of other causes, and 4 survived. Our data suggest that maintenance therapy with amphotericin may be needed to prevent relapse in patients with AIDS.

Nosocomial fungal infection during hospital renovation.

Nosocomial fungal pulmonary infections (Zygomycetes, Aspergillus sp.) developed in two premature infants in a special care unit (SCU) adjacent to an area of renovation. Inspection showed that inadequate barriers permitted the passage of airborne particles between the two areas, and cultures confirmed a significantly higher (p less than or equal to 0.05) density of mold spores in the SCU (0.88 cfu per hour per settling plate) compared to a construction-free comparison area (0.22 cfu per hour per settling plate). The major source of mold was the dust above the hospital's false ceiling. In another construction area, imperious barriers were shown to effectively restrict the dispersal of mold. Our experience adds Rhizopus to Aspergillus as a possible cause of construction-related nosocomial infection. Sporadic episodes will continue to occur until the hazards of renovation are appreciated and effective preventive measures are routinely instituted.

Mycobacterium avium-intracellulare: a cause of disseminated life-threatening infection in homosexuals and drug abusers.

Five men developed disseminated infection with Mycobacterium avium-intracellulare. These patients all lived in the New York City area and presented with their illnesses between January 1981 and September 1981; four were homosexual and one was an intravenous drug abuser. Four patients died. All five patients had defects in the cell-mediated immune response. The infections were characterized histopathologically by poor or absent granulomatous tissue reaction. Clinical isolates of M. avium-intracellulare from all five patients agglutinated commonly used antimycobacterial drugs. The spectrum of opportunistic infections among populations of homosexuals and drug abusers should be expanded to include disseminated disease due to M. avium-intracellulare.

An outbreak of community-acquired Pneumocystis carinii pneumonia: initial manifestation of cellular immune dysfunction.

Eleven cases of community-acquired Pneumocystis carinii pneumonia occurred between 1979 and 1981 and prompted clinical and immunologic evaluation of the patients. Young men who were drug abusers (seven patients), homosexuals (six), or both (two) presented with pneumonia. Immunologic testing revealed that absolute lymphocyte counts, T-cell counts, and lymphocyte proliferation were depressed, and that humoral immunity was intact. Of the 11 patients, one was found to have Kaposi's sarcoma, and another had angioimmunoblastic lymphadenopathy. Eight patients died. In the remaining three, no diagnosis of an immunosuppressive disease was established, despite persistence of immune defects. These cases of pneumocystosis suggest the importance of cell-mediated immune function in the defense against P. carinii. The occurrence of this infection among drug abusers and homosexuals indicates that these groups may be at high risk for this infection.

Rickettsialpox: report of an outbreak and a contemporary review.

Rickettsialpox is a mild illness characterized by the appearance of a primary eschar at the site of a mite bite followed by fever, headache, and a papulovesicular rash. It can be confused with a variety of illnesses including several other rickettsial diseases and chickenpox. R. akari, the etiologic agent, is a rickettsia belonging to the spotted fever group (SFG) of rickettsial illnesses. In spite of significant serologic cross-reactivity with other SFG agents, there is no convincing evidence of cross-immunity to these agents after recovery from rickettsialpox. Tetracyclinie is the drug of choice in the treatment of this disease.

Pseudobacteremia attributed to contamination of povidone-iodine with Pseudomonas cepacia.

Pseudomonas cepacia was recovered from the blood cultures of 52 patients in four hospitals in New York over 6 months from April through October 1980. Epidemiologic investigation in one hospital indicated that the positive results of blood culture represented pseudobacteremias and implicated a 10% povidone-iodine solution used as an antiseptic and disinfectant (Pharmadine; Sherwood Pharmaceutical Company, Mahwah, New Jersey) as the source of contamination. Physicians who drew blood cultures positive for P. cepacia were more likely to have left povidone-iodine on the skin before venipuncture (p = 0.026) and were more likely to have applied povidone-iodine to the blood culture bottle tops and to have left it there while inoculating the blood culture media (p = 0.007) than those who drew cultures negative for P. cepacia. Direct inoculation of Pharmadine into brain-heart infusion broth yielded P. cepacia; however, 2 weeks after the first cultures, the same Pharmadine bottles were culture negative. The iodine concentrations of the contaminated Pharmadine solutions were similar to those of 10% povidone-iodine solutions distributed by other manufacturers.

Infections in hypothermic patients.

Of 59 adults admitted to Bellevue Hospital, New York, between 1968 and 1979 because of hypothermia due to exposure, 24 (41%) had 32 serious infections. Nine infections were not diagnosed at the time of admission. Infected patients warmed to higher peak temperatures were more likely to be comatose and had lower lymphocyte counts. At admission, physicians gave antibiotics to only one of nine patients with occult infection but to ten of 35 uninfected patients, thus failing to identify which patients required prompt antibiotic therapy. Delay in therapy contributed to the death of two patients. Since infection is frequently masked in hypothermic patients, careful repeated evaluations should be carried out to identify early infections. Although the proper use of antibiotics in patients with hypothermia is unresolved, we believe that prompt empiric antibiotic therapy is appropriate.
