Distal ulnar recession for disorders of the distal radioulnar joint.

Thirty-six wrists of 35 patients were treated with distal ulnar recession for pain and limitation of motion associated with chondromalacia of the ulnar head, triangular fibrocartilage complex tears, ulnocarpal impingement, and instability of the distal radioulnar joint. Contributing factors were positive ulnar variance in 31 wrists, fracture of the distal radius in five, sprains in 14, premature closure of the distal radial epiphysis in five, and lax ligamentous habitus in five. The ages of the patients averaged 33 years. Clinical findings were local tenderness, crepitus, and instability evident by a positive "piano key" effect. Roentgenographic findings were positive ulnar variance (29 of 36), zero ulnar variance (four), negative ulnar variance (three), positive arthrogram (11 of 19), and "forme fruste" Madelung's deformity (two). The surgical procedure is a modification of the Milch cuff resection with the use of a dynamic compression plate. Recession ranged from 2 to 13 mm (average of 4 mm). Findings at surgery included chondromalacia of the ulnar head (19), tears of the triangular fibrocartilage complex (11), and excessive mobility of the ulnar head (10). At an average follow-up of 24.5 months, results were excellent in 7 wrists, good in 21, fair in four, and poor in four. Poor results in two wrists were upgraded to good after osteosynthesis of a nonunion in one and recessional osteotomy of the radial sigmoid notch in the other. Ulnar recession offers a less destructive alternative to disorders of the distal radioulnar joint than the Darrach resection.

Incidence of hepatitis B in the penitentiary of New Mexico.

A study was conducted to determine the incidence of hepatitis B (HB) in a prison population. Forty-seven per cent of 455 male prisoners had evidence of past HB infection. HB seropositivity was most strongly correlated with: 1) a history of IV drug abuse; 2) age; 3) total time in any prison; and 4) race. During a one-year study period there were no clinical cases of HB in the prison and the seroconversion rate was 0.8 per cent among prisoners still incarcerated.

Equine antitoxin use and other factors that predict outcome in type A foodborne botulism.

The use of trivalent equine antitoxin in treating foodborne botulism has not been adequately assessed. One hundred thirty-two cases of type A foodborne botulism reported to the Centers for Disease Control in the period from 1973 to 1980 are reviewed to evaluate the effect of antitoxin therapy and other factors on the outcomes of patients with botulism. The fatality rates were higher in patients over 60 years old and in those who were index patients (the first or only patient in an outbreak). The clinical course was longer in patients over 60 years old, patients whose incubation period was less than 36 hours, and index patients. Patients who had received trivalent equine antitoxin had a lower fatality rate and a shorter course than those who did not receive antitoxin, even after controlling for age and incubation period. Patients who received antitoxin in the first 24 hours after onset had a shorter course but about the same fatality rate as those who received antitoxin later. These results suggest that trivalent antitoxin has a beneficial effect on survival and shortens the course of patients with type A botulism.

Wound infections caused by Vibrio vulnificus, a marine vibrio, in inland areas of the United States.

Vibrio vulnificus is a halophilic marine vibrio which may produce infection in wounds exposed to seawater or raw shellfish. The Centers for Disease Control has received two isolates from wounds exposed to inland waters, a New Mexico creek and an Oklahoma reservoir. Halophilic organisms were recovered from both the creek and the reservoir, and the water in both sites was found to be brackish. Both clinical isolates of V. vulnificus grew in salt concentrations as low as those found in the creek and reservoir. These cases illustrate the potential for pathogenic halophilic Vibrio species to live in brackish inland waters and produce infections in patients living in inland areas of the United States.

Animal bites as an occupational hazard among animal control officers.

One hundred-and-two full-time animal control officers (ACOs) in New Mexico were surveyed to learn about animal bite risks in this little-studied occupational group. The overall bite rate was 2.57 per working-year (175-500 times population-based rate estimates). A "high risk" ACO subset (seven officers involved in 67 per cent of bite incidents) was discovered. Evaluation of animal bite data can contribute to prevention of occupational injuries among the estimated 10,000 full-time ACOs in this country.

A pseudo-outbreak of influenza A associated with use of laboratory stock strain.

In November 1982, when influenza type A(H3N2) viruses were spreading in the United States, influenza A(H1N1) viruses were reportedly isolated from 10 hospitalized patients in New Mexico, only two of whom had influenza-like illnesses. Reference stock influenza A/Fort Monmouth (FM)/1/47(H1N1) virus had been used to prepare fluorescent antibody test slides in the laboratory reporting the isolates. After investigation, it was concluded that the isolates from the patients' cultures were a result of laboratory contamination. When an unexpected cluster of unusual virus isolates is reported, the possibility of laboratory contamination should be considered.

Routine pre-exposure rabies prophylaxis: a reassessment.

The rational use of rabies biologics is a difficult challenge. Pre-exposure rabies prophylaxis (PRE-RP) is one important rabies prevention strategy currently recommended by the US Public Health Service for groups considered at high risk of exposure to rabies. However, standard post-exposure rabies prophylaxis (POST-RP) appears equally effective in preventing rabies; PRE-RP still requires a limited vaccination series if a rabies exposure occurs and, at current costs, standard POST-RP may be a less expensive strategy than PRE-RP. For PRE-RP, as with other human rabies prevention strategies, the central problem is to obtain reasonable estimates of actual rabies exposure risks, which provide the rationale for well-designed programs.

Low prevalence of hepatitis B infections among residents of an institution for the mentally retarded in New Mexico.

Residential institutions for the mentally retarded are considered high-risk settings for hepatitis B (HB) infection. Accordingly, HB vaccine is recommended for susceptible clients and selected staff of such facilities. However, a serologic screening program among 364 residents of Los Lunas Hospital and Training School (LLHTS) in New Mexico found only 11 residents to be anti-HBc positive (3%) and only one of these residents was also HBsAg-positive (0.3%). The unexpectedly low prevalence of HB infections at LLHTS probably reflects infrequent HB introductions into the institution. Using these serologic data, a vaccination program was instituted to prevent HB infection among LLHTS residents, thereby eliminating the need for mass screening and HB vaccination of LLHTS employees. Serologic screening among residents of other smaller institutions for the mentally retarded is recommended before design of HB prevention programs for clients and staff.

Economic impact of a botulism outbreak. Importance of the legal component in food-borne disease.

Legal expenses arising from food-borne outbreaks have not been reported in the medical literature, to the best of our knowledge. Expenses of an outbreak of food-borne botulism involving 34 victims in 1978 exceeded +5.8 million. These included outbreak investigation and control (3.2% of total), medical care for patients with botulism from April 1978 through October 1981 (12.3%), and settlements and legal charges (84.4%). Legal actions following food-borne outbreaks must be recognized for several reasons. First, the delay between the outbreak and the conclusion of legal activity (three years in this instance) mandates prompt and meticulous written documentation of investigation and control work. Second, legal expenses may make a large contribution to the total societal impact of food-borne disease outbreaks. Finally, awareness of the legal expense strengthens the rationale for public and private expenditures on food-borne disease prevention in this country.

Toxic shock syndrome related to nasal packing.

While toxic shock syndrome (TSS) is generally considered to be a tampon-related illness, an increasing number of reported cases have been related to surgical wounds. At least one case has been reported following nasal surgery with nasal packing. We report two additional cases of TSS associated with nasal packing. Because nasal packing is in some ways analogous to the use of tampons for menstrual hygiene, and nasal carriage of Staphylococcus aureus is frequent, the scarcity of TSS cases reported to occur following nasal packing is surprising. Otorhinolaryngologists are urged to report TSS cases associated with nasal packing to their state and local health departments or the Centers for Disease Control to aid in the understanding of the pathogenesis of this disease.

Risk of pregnancy among adolescent schoolgirls participating in a measles mass immunization program.

A large measles vaccination program in the Albuquerque, New Mexico public schools in 1981, conducted according to US Public Health Service guidelines, was studied to determine rates of pregnancy among adolescent vaccinees. Pre-vaccination counseling of 1,922 clinic attendees prevented seven pregnant girls from being vaccinated. Despite counseling, of 1,913 female vaccinees age 13-18 years old, two were pregnant at the time of vaccination (1.05 pregnancies per 1,000 vaccinees) and an additional four girls became pregnant in the three months after vaccination (2.1 pregnancies per 1,000 vaccinees). Data supporting low or absent fetal risks from measles and rubella vaccine, combined with the low pregnancy rate among vaccinees documented in this study, support the reasonableness of the recommended strategy for measles and rubella vaccination of secondary schoolgirls.
