Indiana Hospitals To Say, “Oops!” in Public.

New rules adopted by the Indiana State Department of Health will require hospitals to disclose medical errors to the public. Indiana is the second state to implement such a program. The first report under the new rules is expected to be made public in February, and will identify only hospitals, not patients or medical professionals. The new rules require hospitals to report on 27 different mistakes commonly made in hospitals and surgery centers, including surgery on the wrong body part, deaths from contaminated drugs, and sexual assaults on patients. Mistakes must be reported to the state within 15 days of confirmation that the hospital was at fault, and up to six months after an incident. While hospital officials have traditionally been loath to disclose errors, some have come to terms with the new requirement. “Human nature dictates that you tend not to want to expose your weaknesses to the public, but we’re a different type of industry. The consequences are so big,” said Richard Graffis, chief medical officer at Methodist and Indiana University hospitals, and Riley Children’s Hospital. According to state officials, the new rules aim to improve public safety. “It’s not simply a way to take competitive advantage of your cross-town rival,” said University of Pennsylvania medical ethicist Arthur Caplan. “I think we’ll see that people respond to it, try to adjust their behavior and try to institute systems to reduce errors.” 

Woe to the Pomegranate

Pomegranate juice and drug interactions
The noble pomegranate? A threat to one’s health?
The juice, long hailed as an aid to lowering cholesterol, is of some concern to cardiologists, who say in the September 1 issue of the American Journal of Cardiology the juice could interact negatively with antiarrhythmics, immunosuppresants, statins, and protease inhibitors, among others.

Medical Research

Many patient problems caused by medications or adverse drug events are due to dangerous interactions of coprescribed medications. A new study reveals that one-third of primary care patients are prescribed drugs that strengthen the blood-thinning effect of the anticoagulant warfarin.

A second study shows that between 18 and 28 percent of primary care patients are prescribed a drug that can adversely interact with warfarin or three other commonly used drugs. Select to read this article.

Study Condemns F.D.A.’s Handling of Drug Safety

NY Times: WASHINGTON, Sept. 22/06 — The nation’s system for ensuring the safety of medicines needs major changes, advertising of new drugs should be restricted, and consumers should be wary of drugs that have only recently been approved, according to a long-anticipated study of drug safety.

The report by the Institute of Medicine, part of the National Academy of Sciences, is likely to intensify a debate about the safety of the nation’s drug supply and the adequacy of the government’s oversight. The debate heated up in September 2004 when Merck withdrew its popular arthritis drug Vioxx after studies showed that it doubled the risks of heart attacks.

Several senators have already proposed significant changes, some of which the report seems to endorse.

The report’s conclusions are often damning. It describes the Food and Drug Administration as rife with internal squabbles and hobbled by underfinancing, poor management and outdated regulations.

“Every organization has its share of dysfunctions, unhappy staff members and internal disputes,” the report said. But panel members said that they were deeply concerned about the agency’s “organizational health” and its ability to ensure the safety of the nation’s drug supply.

The report made these recommendations, most of which would require Congressional authorization:

¶Newly approved drugs should display a black triangle on their labels for two years to warn consumers that their safety is more uncertain than that of older drugs.

¶Drug advertisements should be restricted during this initial period.

¶The F.D.A. should be given the authority to issue fines, injunctions and withdrawals when drug makers fail — as they often do — to complete required safety studies.

¶The F.D.A. should thoroughly review the safety of drugs at least once every five years.

¶The F.D.A. commissioner should be appointed to a six-year term.

¶Drug makers should be required to post publicly the results of nearly all human drug trials.

In a telephone conference with reporters on Friday, top F.D.A. officials struck an awkward balance between thanking the institute for its work and defending their own leadership. They said they needed to study the report before deciding which of its recommendations to endorse.

“While considerable work has been done over the past two years to improve our approach to drug safety, work still needs to be done,” said Dr. Andrew C. von Eschenbach, the acting commissioner of the agency and the nominee for commissioner.

An internal e-mail message sent Friday to agency staff members by Dr. Sandra L. Kweder, deputy director of the Office of New Drugs, was blunter, bemoaning the report’s criticism of what it described as the agency’s dysfunctional culture.

“It is a long, inflammatory section of the report that will certainly generate the most public attention and hit our people hard,” Dr. Kweder wrote, according to a copy provided to The New York Times.

Agency critics were elated.

“The new report validates what the watchdog community has been saying for the last two years,” said Senator Charles E. Grassley, Republican of Iowa, who as chairman of the Senate Finance Committee has overseen investigations into drug safety problems. “Problems are systemic, and solutions must reflect a new mind-set by the agency leadership.”

The drug industry, through its trade organization, reacted warily. “Though there is always room for improvements, it would be a mistake to accept the notion that the F.D.A. drug safety system is seriously flawed,” said Caroline Loew, senior vice president of the Pharmaceutical Research and Manufacturers of America.

The Institute of Medicine is a nonprofit organization created by Congress to advise the federal government on health issues. The report was issued by the Committee on the Assessment of the United States Drug Safety System, led by Sheila P. Burke, deputy secretary and chief operating officer of the Smithsonian Institution.

The report described fierce disagreements between those who approve drugs and those who study their effects after approval, disputes that repeated F.D.A. efforts have not resolved. Indeed, managers’ failure to address such disagreements competently “has played an important role in damaging the credibility” of the agency, it said.

Critics of the food and drug agency have long been divided into two warring camps. Some say the agency fails to approve life-saving medicines quickly enough, while others say that it is so intent on rapid approvals that it fails to ensure the safety of the drugs.

The institute’s report champions the latter view by calling for greater caution. It suggests that one of the agency’s biggest problems is a deal struck in 1992 between Congress and the drug industry in which drug makers agreed to pay millions in fees to speed reviews. This deal has increased pressures on drug reviewers to act quickly, and it has limited “the ability of reviewers to examine safety signals as thoroughly as they might like,” the report said.

“Some also have serious concerns that the regulator has been ‘captured’ by industry it regulates, that the agency is less willing to use the regulatory authority at its disposal,” the report said, criticizing the agency’s regulatory tools as “all-or-nothing.”

“The agency needs a more nuanced set of tools to signal uncertainties, to reduce advertising that drives rapid uptake of new drugs, or to compel additional studies in the actual patient populations who take the drug after its approval,” it said.

The pharmaceutical industry is likely to fight at least some of the proposals, said Charlie Cook, a Washington political analyst.

“One should never underestimate the influence of the drug industry,” Mr. Cook said. “But I would think that at least the outlines of many of these recommendations would have a decent chance of getting through Congress.”

Senators Michael B. Enzi, Republican of Wyoming and chairman of the Health, Education, Labor and Pensions Committee, and Edward M. Kennedy of Massachusetts, the ranking Democrat on the committee, have jointly proposed a bill that would undertake at least some of the changes advocated by the report.

Another bill, sponsored by Senator Grassley and Senator Christopher J. Dodd, Democrat of Connecticut, offers similar proposals.

There is little chance that Congress will act on any of these proposals before next year, when it must reauthorize the 1992 financing deal with the drug industry. Negotiations between the drug industry and agency about the parameters of that deal are already under way.

Despite its fierce criticisms, the report may bolster the confirmation prospects of Dr. von Eschenbach. A Senate committee approved his nomination on Wednesday, but two Republican senators have vowed to block it.

Over the past 10 years, no commissioner has served more than two years, though the term is open-ended. The report deplored this “lack of stable leadership.”

“Without stable leadership strongly and visibly committed to drug safety, all other efforts to improve the effectiveness of the agency or position it effectively for the future will be seriously, if not fatally, compromised,” the report states.

It recommends that the commissioner be nominated for a six-year term, but such a change may not solve the problem of early exits. President Bush has nominated two past commissioners. The first left for another job within the administration; the second left amid accusations of financial improprieties.

The report recommends that Michael O. Leavitt, the secretary of health and human services, appoint an independent board to advise the commissioner “to implement and sustain the changes necessary to transform” the agency’s culture.

It rejects suggestions by Mr. Grassley and others that the F.D.A. create a center for drug safety to monitor drugs after approval.

“Achieving a balanced approach to the assessment of risks and benefits would be greatly complicated, or even compromised, if two separate organizations were working in isolation from one another,” the report concludes.

The F.D.A. asked the Institute of Medicine to review its drug safety system shortly after the Vioxx withdrawal in 2004, and the agency has agreed to pay $3 million for the study.

4 Case Reports of Imported Bahamanian Malaria

September 22, 2006 / 55(37);1013-1016

 

Malaria — Great Exuma, Bahamas, May–June 2006

 

Malaria in humans is caused by four distinct protozoan species of the genus Plasmodium (P. falciparum, P. vivax, P. ovale, and P. malariae). These parasites are transmitted by the bite of an infective female Anopheles mosquito (1). In the Caribbean region, malaria has been eliminated from all islands except Hispaniola, the island consisting of Haiti and the Dominican Republic. Elimination of malaria elsewhere resulted from a combination of integrated control measures, socioeconomic development, and close public health surveillance. However, even Caribbean islands where malaria is no longer endemic remain at constant risk for reintroduction of the disease because of their tropical climate, presence of competent malaria vectors, and proximity to other countries where malaria is endemic. This susceptibility was underscored by the recent outbreak of malaria on the island of Great Exuma in the Bahamas; during May–June 2006, a total of 19 malaria cases were identified. Four of the cases, in travelers from North America and Europe, are described in this report; such cases of imported malaria can signal the presence of a malaria problem in the country visited and thus assist local health authorities in their investigations. On September 19, after 3 months with no report of new cases, CDC rescinded its previous recommendation that U.S.-based travelers take preventive doses of the antimalarial drug chloroquine before, during, and after travel to Great Exuma.*

Case 1. On May 24, 2006, a man aged 33 years from the United States received a diagnosis of malaria in a hospital emergency department in Virginia. The patient had intermittent fever, sweats, abdominal discomfort, nausea, and vomiting, which had begun during a May 4–7 visit to Great Exuma, where the patient had stayed in a resort hotel. The patient had no history of exposure to malaria. Blood smears on May 24 indicated P. falciparum. After outpatient treatment with chloroquine, changed later to quinine and doxycycline, the patient recovered uneventfully.

Case 2. On June 6, a woman aged 29 years from Germany received a diagnosis of P. falciparum malaria in a hospital in Germany. She had experienced fever, headache, nausea, and vomiting since May 30, near the end of a May 18–31 visit to Great Exuma. After her return to Germany, the woman was treated initially with antibiotics for suspected sinusitis. However, her illness persisted, and she was hospitalized on June 6 with high fever and neck stiffness. Diagnostic tests included magnetic resonance imaging of her head, a lumbar puncture to exclude meningitis, and a blood smear that revealed P. falciparum. She was treated with artemether-lumefantrine and recovered.

Case 3. On June 16, a man aged 20 years from Canada had P. falciparum malaria diagnosed. The man had been born in the Bahamas and had visited friends and relatives there during April 19–June 11, spending most of his time in Georgetown, the most populous city on Great Exuma. On June 14, the man experienced fever and chills and went to an emergency department for evaluation after learning that his cousin had been treated recently for malaria on Great Exuma. The diagnosis of P. falciparum malaria was confirmed by blood smear on June 16. He was treated on an outpatient basis with chloroquine followed by atovaquone-proguanil and recovered uneventfully.

Case 4. A man aged 66 years from the United States, who lived on a boat, received a diagnosis of P. falciparum malaria on June 19. The man, who had not recently visited any area that was endemic for malaria, stayed in Great Exuma from late April to late May. In early May, he began experiencing fever, chills, sweats, headaches, and fatigue but did not seek medical care; he left Great Exuma to sail to other Bahamian islands. On June 18, on his return to Great Exuma, the patient learned of the outbreak and went the next day to the district medical clinic, where he received a diagnosis of P. falciparum malaria. He was treated with chloroquine and primaquine and recovered uneventfully.

After report of the first case in Virginia, the Bahamian Ministry of Health (MOH) initiated epidemiologic and entomologic investigations with the technical assistance of the Pan American Health Organization. MOH also heightened mosquito-control activities that were already being conducted on Great Exuma in conjunction with the Bahamian Department of Environmental Health Services.

Active case detection was conducted on Great Exuma during June 6–30; however, no case of malaria was diagnosed later than the June 19 diagnosis in case 4. Persons examined at primary-care clinics who had a history of fever and a temperature of >99.0ºF (>37.2ºC) and contacts of persons who received diagnoses of malaria were screened using thick and thin blood smears stained with Wright’s stain. On Great Exuma, 15 persons were determined infected with P. falciparum. Ages ranged from 16 to 66 years (median: 36 years); 84% were males. Most of these patients were residents of the Bahamas, clustered around the areas of Georgetown and Bahama Sound, and living in close proximity to a community of immigrants from Haiti; most said they had not recently traveled to Haiti or any other area endemic for malaria. All patients were initially treated with chloroquine and doxycyline; the latter was subsequently replaced by primaquine to eliminate gametocytes and thus prevent further transmission. All 15 patients recovered.

A parasite prevalence survey was conducted on Great Exuma in a community of immigrants from Haiti, from which anecdotal reports of illness had been received. Of 159 persons who consented to testing, 29 adults were determined infected with P. falciparum. This finding prompted mass treatment with chloroquine and primaquine of 203 persons within that community.

Entomologic surveys were conducted in multiple sites near bodies of fresh water identified by ground and air surveys in Great Exuma. Human bait and CDC light-trap collections yielded large populations of mosquitoes, of which only five were adult Anopheles albimanus. Surveys of potential breeding sites indicated few areas favorable for breeding of An. albimanus larvae, with five confirmed An. albimanus larvae collected from three breeding sites. Mosquito-control interventions were intensified beginning May 30. These measures included spraying 1) at all potential breeding sites, 2) within a quarter-mile radius of patients with confirmed cases, and 3) within a half-mile radius of patients detected through contact tracing, initially with a water-based pyrethroid insecticide, and later with malathion 96.5%. In addition, all bodies of fresh water on Great Exuma, neighboring Little Exuma, and surrounding cays (reefs) were treated with temephos to eliminate larvae.

As of September 19, no additional cases of malaria had been identified on Great Exuma or any other island in the Bahamas, despite intense epidemiologic surveillance. Mosquito-control measures were being continued throughout the Bahamas.

Editorial Note:

 

The Bahamas is an archipelagic nation in the northern Caribbean Sea, consisting of approximately 700 islands and 2,400 cays stretching between Florida and Haiti (Figure). Persons from Hispaniola and other countries have emigrated to the Bahamas, where malaria is not endemic and only one imported case was reported in 2005. However, because of frequent travel and relocation among countries, health-care providers in the Bahamas and other countries where malaria is not endemic should remain alert to the risk for this disease, especially in travelers and immigrants. Introduced malaria is much less common than imported malaria but of greater epidemiologic significance. Imported malaria usually occurs when travelers acquire the infection while visiting areas where malaria is endemic. Introduced malaria typically occurs when infected travelers return home and transmit the infection to local Anopheles mosquitoes, which subsequently transmit it to local residents. Left unchecked, this process can result in reestablishment of endemic malaria in countries that have previously eliminated the disease because these areas have climatic conditions favorable to transmission and Anopheles species that are receptive to malaria parasites. In the United States, 1,320 cases of imported malaria were reported in 2004 (1), and 63 episodes of introduced malaria were detected from 1957 to 2003, the year when the latest episode occurred in Florida (24).

Available evidence indicates that during May–June 2006, Great Exuma experienced an outbreak of introduced malaria that was successfully contained and terminated. The observations that all cases were caused by P. falciparum and a substantial proportion of patients were immigrants from Haiti suggest that malaria was introduced by those immigrants. All patients treated with chloroquine responded to the treatment, which is a further suggestion that the parasites originated from Haiti, where P. falciparum has remained sensitive to chloroquine. P. falciparum causes 99% of malaria cases in Haiti and the Dominican Republic (MD Milord, Ministry of Public Health and Population, Haiti, and JM Puello, National Center for Control of Tropical Diseases, Dominican Republic, personal communication, 2006), which share the only Caribbean island still endemic for malaria. Conversely, P. vivax causes 94% of cases in Mexico and Central America (5).

The successful containment of this malaria outbreak is attributable to several factors. The first identified case, detected in a foreign tourist returning from the Bahamas, was promptly reported to the Bahamian MOH, which responded with several complementary interventions, including identification and treatment of patients and asymptomatic parasite carriers and institution of mosquito-control measures. Fewer than 30 days elapsed between diagnosis of the first identified case in Virginia and diagnosis of the last case on Great Exuma. Since June 19, no additional cases have been noted, despite intensive ongoing surveillance among febrile patients.

In view of these findings, CDC has rescinded recommendations made on June 16, 2006, that travelers take preventive doses of chloroquine before, during, and after travel to Great Exuma. As of September 19, CDC no longer recommends that travelers to Great Exuma take antimalarial prophylaxis.

This malaria outbreak illustrates the importance of vigilance by health-care providers and rapid response by public health authorities for successful containment (2) and also might provide incentive for measures to eliminate malaria from all Caribbean islands, including Hispaniola. Recently, the International Task Force for Disease Eradication recommended that Haiti and the Dominican Republic work jointly to eliminate from Hispaniola both malaria and lymphatic filariasis, two vectorborne parasitic diseases that have been eliminated from all other Caribbean islands (6). Agreements reached in July 2006 between the ministries of health of Haiti and the Dominican Republic represent a first step toward achieving this goal.

from Heartwire — a professional news service of WebMDSeptember 5, 2006 — In a study published in the September 4 Rapid Access issue of Circulation, investigators question how sudden is cardiac death and say their findings suggest that death might not emerge “suddenly out of the blue.” Rather, they report that cardiac death is often preceded by symptoms of heart disease for more than an hour, suggesting that many patients have known cardiac disease before the fatal event.

“In conclusion, our data show that ’sudden cardiac death’ is not nearly as sudden in most cases as the term may suggest. Warning symptoms that precede sudden cardiac death are present for a surprisingly long time in many patients. These symptoms are misinterpreted, suppressed, or denied despite the presence of a preexisting cardiac disease or cardiac risk factors,” write Dirk Müller, MD, from the Universitätsmedizin Berlin in Berlin, Germany, and colleagues. The group also adds: “These findings suggest that educating the public, patients, and relatives to recognize and respond to symptoms of heart disease holds promise for reducing mortality attributed to sudden death.”

To develop a better understanding of the circumstances of sudden cardiac death, with an intention of developing preventive measures and proper reactions to the impending events, Müller and colleagues collected information on cases of out-of-hospital sudden cardiac death in the emergency medical system of Berlin, Germany. At their center, a physician-manned mobile intensive care unit and rescue helicopter covered approximately 10% of the 3.5 million inhabitants of the city. During a case of sudden cardiac arrest, the emergency physician interviewed all available bystanders and witnesses via questionnaire. The questionnaire, developed during a previous pilot study, was used to obtain the patient’s medical history, medication use, and any preceding signs or symptoms, as well as their duration.

Of 5831 rescue missions during a 1-year period, 406 involved patients with presumed cardiac arrest. In 72%, the arrest occurred at home, and in 67%, the arrest occurred in the presence of an eyewitness. Information on symptoms immediately preceding the event was available in 80% of all patients (n = 323), including 274 cases of witnessed cardiac arrest. Bystanders performed a resuscitation effort in just 57 patients, of whom 13 survived to discharge. Of those without bystander cardiopulmonary resuscitation (CPR), just 13 (3.72%) of 349 patients survived to discharge.

Information on the medical history was available in 352 patients. Of these, 106 had a history of coronary heart disease documented by angiography, while another 127 subjects had coronary disease as suggested by angina pectoris or antianginal medications. Approximately 10% of subjects had a history of hypertension. Regarding symptoms preceding the arrest, angina was present in 22% of patients with known symptoms for an average of 2 hours prior. Dyspnea, nausea/vomiting, and dizziness or syncope were other commonly reported symptoms.

“The hypothesis that the majority of cases of sudden cardiac death will seemingly occur at random in an apparently healthy or at least very low-risk population is, however, not supported by the findings of the present investigation,” write the authors. “In the present study, the majority of patients in an unselected population had a history of documented cardiac disease or at least typical symptoms of coronary heart disease or relevant risk factors that exposed them to an obviously increased risk.”

The group notes that vast majority of sudden death occurs in the home, rather than in public places where a defibrillator might be available. Additionally, the study points to a low bystander resuscitation rate. These data underscore the importance of training in CPR and might explain the limited efficacy of public access defibrillation programs in combating sudden death, the authors write.

Learning Objectives for This Educational Activity

Upon completion of this activity, participants will be able to:

  • Describe the most likely location, symptoms, and causes of sudden cardiac death.
  • Describe the duration of symptoms preceding and predictors of survival for sudden cardiac death.

Clinical Context

Sudden cardiac death is one of the most frequent causes of death in industrialized societies with a yearly incidence estimated at 100 cases per 100,000 inhabitants. Certain risk factors have been identified, including use of nicotine, caffeine, and specific drugs with some trigger, such as psychological or physical stress. According to the current authors, tachyarrhythmic events are presumed to be the most common precipitating event for sudden cardiac death with coronary heart disease as a background condition. Patients with tachyarrhythmias compared with asystole or pulseless electrical activity had a much better expected prognosis with CPR.

Little is known about the exact circumstances preceding sudden cardiac death, the most common location for sudden cardiac deaths to occur, or the role of eyewitnesses or the effects of bystander resuscitation, according to the current authors.

The study authors conducted an observational prospective study of sudden cardiac death for 1 year in one city, using emergency physicians to interview bystanders and witnesses for information preceding sudden cardiac death to determine the most likely location, duration of, and factors related to survival in patients presenting with sudden cardiac death.

Study Highlights

  • Sudden cardiac death was defined as unexpected arrest of presumed cardiac origin in adults older than 18 years occurring within 24 hours of onset of any symptoms interpreted as being of cardiac origin.
  • Excluded were cases with longer symptom duration and arrests of noncardiac origin (eg, trauma, suicide, or intoxication).
  • Data were collected by emergency physicians called to the sudden cardiac death by a second-tier mobile intensive care unit and the rescue helicopter.
  • The physician collected data on logistics, demographics, medical history, medication use, and preceding signs and symptoms from eyewitnesses.
  • Follow-up continued until after hospital discharge or failure of resuscitation.
  • 5831 missions were performed, and 406 patients qualified for analysis.
  • 58% were men. Mean age was 71 years. Women were significantly younger than men (68 vs 76 years; P < .0001).
  • The sudden cardiac death was witnessed or overheard in 67% of cases.
  • Of those sudden cardiac deaths witnessed, 66% of witnesses were relatives of the patients.
  • Bystanders performed resuscitation attempts in only 14% of patients.
  • First registered arrhythmias were ventricular fibrillation (39%), pulseless electrical activity (33%), and asystole (28%) in those with bystander CPR attempts.
  • The corresponding frequencies were 25%, 25%, and 50% for patients without bystander CPR.
  • With bystander CPR, 23% of patients survived to discharge vs 4% without bystander CPR.
  • Fewer bystander resuscitations were observed at home (11%) than at other locations (26%) (P < .001).
  • The rate of bystander CPR was 8% for related persons, 15% for acquainted persons, and 23% for those with no relationship to the patient.
  • A medical history was available in 87% of cases.
  • 30% had a history of coronary heart disease documented by angiography.
  • Of those with preceding symptoms, 36% had symptoms suggestive of angina pectoris or intake of anginal medications before the sudden cardiac death.
  • The remaining patients had a history of hypertension, diabetes, smoking, or chronic obstructive pulmonary disease.
  • In 80% of patients, information was available about preceding symptoms.
  • Angina was present for a median of 120 minutes in 22% of patients.
  • Dyspnea was present for a median of 30 minutes in 15% of patients.
  • Nausea or vomiting was present for a median of 120 minutes in 7% of patients.
  • Dizziness or syncope was present for a median of 10 minutes in 5% of patients and other symptoms for a median of 60 minutes in 6% of patients.
  • 25% of patients had no complaints prior to sudden cardiac death.
  • In patients with witnessed sudden cardiac death, 25% had angina pectoris for 120 minutes, 17% had dyspnea for 10 minutes, 7% had nausea or vomiting for 90 minutes, 7% had dizziness or syncope for 10 minutes, and 8% had other symptoms for 60 minutes.
  • 25% of cases with eyewitnesses had no complaints prior to sudden cardiac death.
  • Distribution and duration of symptoms were similar between witnessed and unwitnessed patients.
  • Patients at home tolerated their symptoms for much longer before collapse from sudden cardiac death (75 vs 20 minutes in public places).
  • The majority of sudden cardiac deaths occurred in an apartment or residence with low bystander resuscitation rate and longer duration for arrival of a defibrillator.
  • Patients were more likely to survive when the arrest occurred in public places where the emergency services had faster access.
  • Resuscitation attempts were more likely to occur in public places with bystanders.

Pearls for Practice

  • Sudden cardiac death is more likely to occur at home than in public places and most common symptoms are angina, dyspnea, and nausea and vomiting.
  • Duration of symptoms preceding sudden cardiac death varies from 20 to 75 minutes, and survival is improved if the sudden cardiac death occurs in a public place with bystander resuscitation.

Outbreak of Botulinum toxin Type A associated with bottled carrot juice

A commercial beverage has been confirmed as the cause of a cluster of three botulism cases in Georgia. The three patients had onset of symptoms on Friday, September 8th, after consuming a common meal that included commercially produced carrot juice on Thursday, September 7th. Two bottles of juice were consumed. All three patients drank from bottle #1; whether all three patients drank from bottle #2 is unknown. Botulinum toxin type A was identified in the serum and stool of all three patients by mouse bioassay. Subsequently, botulinum toxin type A was identified from carrot juice remaining in bottle #1 by mouse bioassay. Bottle #2 had been rinsed with water, and the test for toxin was negative. The label on the implicated bottle reads “Bolthouse Farms, Bakersfield, California, 100% carrot juice.” The use by date is 09-18-06.

The investigation is ongoing. It is unknown whether the contaminated juice was subjected to time or temperature abuse that might have facilitated the growth of Clostridium botulinum spores, which can survive pasteurization. CDC has not been notified of any cases of suspected botulism since this cluster was reported on September 8. We encourage state and local officials to inquire specifically about consumption of carrot juice in the food history of suspect botulism cases.

CDC has dispatched a notice of this outbreak to public health officials in all 50 states through the Foodborne Disease Listserve, reminding them about the contact numbers for CDC’s Botulism Clinical Consultation and Antitoxin Release Service. The Georgia Department of Health issued an Epi-X alert, alerts to Georgia clinicians and local health officials, and a press release about this outbreak and the implicated food. We anticipate that the Food and Drug Administration (FDA) will be issuing a press release about this outbreak and advising consumers to properly refrigerate juices and follow other food safety guidelines for illness prevention.

Any suspected botulism case reported by a clinician to a state health department should be reported immediately by the state to CDC via the 24/7 CDC Botulism Clinical Consultation and Antitoxin Release Service, by calling the CDC Emergency Operations Center at (770) 488-7100 and asking for the botulism officer on call.

Multiple States Investigating a Large Outbreak of E. coli O157:H7
Infections Public health officials in multiple states, with the
assistance of the Centers for Disease Control and Prevention, are
investigating a large outbreak of E. coli O157:H7 infections. Thus far,
50 cases with isolates demonstrating pulsed-field gel electrophoresis
(PFGE) CDC PulseNet pattern number EXHX01.0124, as determined by Xba
restriction enzyme DNA digestion, have been reported from CT (1), ID
(3), IN (4), MI (3), OR (5), NM (2), UT (11), WI (20).  Eight patients
developed the hemolytic uremic syndrome (HUS) and one patient died.
Most cases are recent: for those with known illness onset, the range of
onset is 08/25/2006 to 09/03/2006
.  The outbreak is likely ongoing.
Preliminary findings from case interviews indicate that pre-packaged
spinach is the most likely source.  Additional investigation is
necessary to determine the brand or brands of pre-packaged spinach
involved.  State and CDC investigators are working with FDA to quickly
gather information to take action to protect the public.  The FDA
advises that consumers not eat bagged fresh spinach at this time.
The E. coli O157:H7 bacterium causes diarrhea that is often bloody and
accompanied by abdominal cramps, but fever is absent or mild. The
illness typically resolves within a week.  However, some people,
especially young children and the elderly, develop the hemolytic uremic
syndrome, or HUS.
For more information concerning E. coli O157 infection, please see the
CDC internet website:

This’ll Scare the Hospital’s Legal Department

WAUKEGAN, Illinois (AP) — A coroner’s jury has declared the death of a heart attack victim who spent almost two hours in a hospital waiting room to be a homicide. 

Beatrice Vance, 49, died of a heart attack, but the jury at a coroner’s inquest ruled Thursday that her death also was “a result of gross deviations from the standard of care that a reasonable person would have exercised in this situation.” 

A spokeswoman for Vista Medical Center in Waukegan, where Vance died July 29, declined to comment on the ruling.

Vance had waited almost two hours for a doctor to see her after complaining of classic heart attack symptoms — nausea, shortness of breath and chest pains, Deputy Coroner Robert Barrett testified. 

She was seen by a triage nurse about 15 minutes after she arrived, and the nurse classified her condition as “semi-emergent,” Barrett said. He said Vance’s daughter twice asked nurses after that when her mother would see a doctor. 

When her name was finally called, a nurse found Vance slumped unconscious in a waiting room chair without a pulse. Barrett said. She was pronounced dead shortly afterward. 

Barrett said he subpoenaed records after finding discrepancies in the hospital’s version of events. 

It wasn’t immediately clear if the ruling would lead to criminal charges. Dan Shanes, a chief of felony review for the state attorney’s office, said his division needed to review the case. 

Vista Medical Center spokeswoman Cheryl Maynen said the hospital, just north of Chicago, cooperated with the coroner’s investigation and had also investigated the incident. She declined to comment on the homicide ruling.

C. difficile in the very young

SUBJECT: Clostridium difficile-associated disease in infants

Recently, the Centers for Disease Control and Prevention (CDC) has been
receiving reports of clusters of neonates and infants with
gastrointestinal symptoms who are testing positive for Clostridium
difficile.  Many experts believe that C. difficile does not cause
symptomatic disease in children less than 1 or 2 years.  CDC is
gathering information about the magnitude of the problem and is seeking
reports of additional cases.

Please provide your contact information if you have you seen an increase
in or cluster of diarrhea or gastrointestinal symptoms in children less
than 2 years of age who have tested positive for C. difficile, either by
toxin testing, tissue cytotoxic assay, or anaerobic stool culture during
2005 and 2006.

Spain Bans Anorexic Models

Apparently, a law has been passed in Spain that prevents skinny models from modeling at fashion shows.  People have actually been hired to measure each model’s Body-to-Mass Index.  Now I know what I’ll be doing when I retire.  Hasta la vista, baby!

FDA Warning on Serious Foodborne E.coli O157:H7 Outbreak

The U.S. Food and Drug Administration (FDA) is issuing an alert to consumers about an outbreak of E. coli O157:H7 in multiple states that may be associated with the consumption of produce. To date, preliminary epidemiological evidence suggests that bagged fresh spinach may be a possible cause of this outbreak. 

Based on the current information, FDA advises that consumers not eat bagged fresh spinach at this time. Individuals who believe they may have experienced symptoms of illness after consuming bagged spinach are urged to contact their health care provider. 

“Given the severity of this illness and the seriousness of the outbreak, FDA believes that a warning to consumers is needed. We are working closely with the U.S. Centers for Disease Control and Prevention (CDC) and state and local agencies to determine the cause and scope of the problem,” said Dr. Robert Brackett, Director of FDA’s Center for Food Safety and Applied Nutrition (CFSAN). 

E. coli O157:H7 causes diarrhea, often with bloody stools. Although most healthy adults can recover completely within a week, some people can develop a form of kidney failure called Hemolytic Uremic Syndrome (HUS). HUS is most likely to occur in young children and the elderly. The condition can lead to serious kidney damage and even death. To date, 50 cases of illness have been reported to the Centers for Disease Control and Prevention, including 8 cases of HUS and one death. 

At this time, the investigation is ongoing and states that have reported illnesses to date include: Connecticut, Idaho, Indiana, Michigan, New Mexico, Oregon, Utah and Wisconsin

FDA will keep consumers informed of the investigation as more information becomes available. 

 

Beta-blockers Still Underutilized in the Emergency Department

ß-blocker Use In Elderly ED Patients With Acute Myocardial Infarction

Vega DD, Dolan KL, Pollack ML
Am J Emerg Med. 2006;24:435-439

Study Summary

A retrospective chart review of patients presenting to a single emergency department (ED) with ST-elevation acute myocardial infarction (STEMI) was conducted from December 2001 through October 2003. Demographic information and contraindications to beta-blocker use were noted (systolic blood pressure < 100 mm Hg, heart rate < 60 bpm, second- or third-degree heart block, acute asthma, acute exacerbation of chronic obstructive pulmonary disease, or acute congestive heart failure).

A total of 385 patients who met the inclusion criteria were included in the analysis. Most of the patients were male (63%) and 60 years of age or older (71%). In this group, 141 patients (37%) had contraindications to beta-blocker therapy. Of the remaining 244 patients, just over half (53%) did not receive a beta-blocker in the ED. Among patients over 60 years of age, 59% did not receive a beta-blocker, compared with 41% in the younger age bracket. Among females, 51% did not receive a beta-blocker, while 54% of males remained untreated.

Viewpoint

The availability of treatment guidelines based on substantial published data is increasing. Despite this availability, many effective therapies are underutilized. In this study, only about half of the patients presenting to the ED with STEMI were treated with beta-blockers, even though no contraindications were evident. This study was a chart review, so additional data might have been available and the statistic different in a prospective study. Data collected during this study indicate that the elderly are not receiving beta-blockers as frequently as younger patients are. Pharmacists practicing in the health-system environment must continue to educate other clinicians on the benefits of and true contraindications to treatments contained within guidelines, and they must persevere to increase the usage of these valuable therapies.
