An acupuncture-associated outbreak of hepatitis B in Jerusalem

Infectious diseases among Ethiopian immigrants in Israel: a descriptive literature review

The mass immigration of Ethiopian Jews to Israel began in the 1980s. For most of these immigrants this was a time of sharp transition from a village life with very basic living conditions, in most cases without a regular supply of water, electricity, or healthcare services, to a modern Western urban society. The aim of this review was to search the medical literature on the characteristics of infectious diseases that are typical in Ethiopian immigrants (EI), using relevant keywords. There has been success in coping with diseases among EI, that are rare although recognized in Israel, in terms of screening and early identification. TB was common in Ethiopia over all the years of immigration to Israel. In contrast, HIV appeared in EI from 1999 when they had long stayovers in transition camps in Gondar and Addis Ababa where there was a high risk of infection with sexually transmitted diseases. There were often delays in diagnosing 'exotic' diseases that are endemic in Africa, but not well known in Israel, such as Onchocerciasis, Schistosomiasis, Strongyloidiasis, and Bartonella endocarditis, which cause severe morbidity and mortality among EI. We describe the effect on general morbidity in Israel, and how the healthcare services coped with these diseases, including obstacles, and failures and successes. In light of the ongoing immigration of African refugees to the United States and Europe, the Israeli experience can be of value to healthcare policy makers in developing strategies for the effective management by medical staff treating these immigrants.

Complications of Acupuncture

Acupuncture as a treatment modality is now more widely used by the medical profession. It behoves both practitioners and patients to be aware of possible complications, the majority of which can be avoided with cautious and prudent use of this ancient therapy.

There have been many isolated reports of complications of acupuncture in the literature. We surveyed the literature identifying all articles referring to complications of acupuncture. Our findings are presented and discussed.

A Cumulative Review of the Range and Incidence of Significant Adverse Events Associated with Acupuncture

Objective

To summarise the range and frequency of significant adverse events associated with acupuncture in order to provide evidence on which to base continuing efforts to improve the safety of acupuncture practice.

Methods

Searches were conducted of computerised databases, previous reviews of case reports, population surveys, prospective surveys of acupuncture practice and relevant sections of textbooks for primary and secondary reports to indicate the range of significant adverse events associated with acupuncture. Data from prospective surveys of acupuncture were combined to estimate the incidence of serious adverse events.

Results

A total of 715 adverse events was included. There were 90 primary reports of trauma, and 186 secondary reports; the most common were pneumothorax and injury to the central nervous system. Infection accounted for 204 primary reports and 91 secondary reports. Over 60% of these cases were hepatitis B. The next most common infection was of the external ear, as a complication of auricular acupuncture. The 144 miscellaneous events mainly comprised seizures and drowsiness judged severe enough to cause a traffic hazard. There were 12 primary reports of deaths. According to the evidence from 12 prospective studies which surveyed more than a million treatments, the risk of a serious adverse event with acupuncture is estimated to be 0.05 per 10 000 treatments, and 0.55 per 10 000 individual patients.

Conclusions

The risk of serious events occurring in association with acupuncture is very low, below that of many common medical treatments. The range of adverse events reported is wide and some events, specifically trauma and some episodes of infection, are likely to be avoidable.

Outbreak of acute hepatitis B virus infection associated with exposure to acupuncture

Background

The most common risk factors for acute hepatitis B virus (HBV) infection are sexual contact, injection drug use and perinatal, or nosocomial exposure. Acupuncture, used in China for over 2,500 years, has been gaining popularity as an alternative medical therapy in the western world, but when associated with poor infection control practices, is also a risk for blood-borne infections.

Objective

To describe the outbreak investigation following detection of two cases of acute HBV infection associated with acupuncture services from the same provider within four months of symptom onset.

Methods

The outbreak investigation included genotyping of HBV from the identified cases, on-site assessment of the acupuncturist's infection prevention and control practices and chart review of known clients.

Results

Both cases had HBV genotype D1 with an identical fingerprint and both clients had visited the clinic on the same day denying other recent risk exposures. Inspection of the acupuncturist's practice revealed high-risk re-use and inappropriate storage of disposable needles. The Regional Health Authority ordered cessation of clinic practice until infection control measures were remediated. A public service announcement and mailed notifications to clients identified from practitioner records recommended that all clients be tested for HBV, human immunodeficiency virus (HIV) and hepatitis C.

Conclusions

A clear epidemiological linkage of these two acute HBV infections to the same acupuncture clinic, evidence of substandard infection control practice in the clinic and identical HBV molecular and genotypic profiles of the two cases are highly suggestive that contaminated acupuncture needles likely resulted in at least two cases of acute HBV infection. This is the first known reported transmission of HBV from acupuncturists re-use of disposable needles and the first HBV outbreak associated with exposure to acupuncture reported this century in an industrialized country. Increased provider oversight and patient education may prevent future outbreaks.

An outbreak of Mycobacterium tuberculosis infection associated with acupuncture in a private clinic of Zhejiang Province, China, 2012

BACKGROUND

Acupuncture carries the potential risk of transmission of pathogenic microorganisms from the environment to the patient, and from one patient to another. An outbreak of tuberculosis at a private clinic in eastern China was investigated to identify the source of infection, mode of transmission, and risk factors for infection.

METHODS

A probable case was one who had the onset of unexplained pain, swelling, or abscess in the area of invasive treatment between January 1, 2011 and February 23, 2012. A confirmed case was a probable case with positive laboratory test results for Mycobacterium tuberculosis. Patient history and the frequency of invasive treatment were compared between 56 probable and confirmed cases and 98 controls in a case-control study.

RESULTS

Fifty-six of 2561 patients (2.2%) who had visited the clinic developed tuberculosis. The odds ratio (OR) of M. tuberculosis infection increased with the frequency of clinic visits (Chi-square for trend=28.943, p=0.000). Multivariate analysis showed that the frequency of acupuncture (Chi-square=24.258, adjusted p-value=0.000) and sharing acupuncture needles (Chi-square=8.936, adjusted p-value=0.003) were risk factors for M. tuberculosis infection. Thirty-two pus sample and nine sputum sample cultures were M. tuberculosis-positive.

CONCLUSIONS

This outbreak was caused by acupuncture and was transmitted through sharing acupuncture needles contaminated with M. tuberculosis.

Examination of surface conditions and other physical properties of commonly used stainless steel acupuncture needles

OBJECTIVES

The present work examined the surface conditions and various other physical properties of sterilised single-use stainless steel acupuncture needles from two of the most popular brands widely used in many countries.

METHODS

Scanning electron microscope (SEM) images were taken for 10 randomly chosen needles from each brand. Further SEM images were taken after each of these needles underwent a standard manipulation with an acupuncture needling practice gel. A comparison of forces and torques during the needling process was also carried out.

RESULTS

The SEM images revealed significant surface irregularities and inconsistencies at the needle tips, especially for needles from one of the two brands. Metallic lumps and small, loosely attached pieces of material were observed on the surfaces of some needles. Some of the lumps and pieces of material seen on the needle surfaces disappeared after the acupuncture manipulation. If these needles had been used on patients, the metallic lumps and small pieces of material could have been deposited in human tissues, which could have caused adverse events such as dermatitis. Malformed needle tips might also cause other adverse effects including bleeding, haematoma/bruising, or strong pain during needling. An off-centre needle tip could result in the needle altering its direction during insertion and consequently failing to reach the intended acupuncture point or damaging adjacent tissues.

CONCLUSIONS

These findings highlight the need for improved quality control of acupuncture needles, with a view to further enhancing the safety and comfort of acupuncture users.

An exploration of the needling depth in acupuncture: the safe needling depth and the needling depth of clinical efficacy

Objective. To explore the existing scientific information regarding safe needling depth of acupuncture points and the needling depth of clinical efficacy. Methods. We searched the PubMed, EMBASE, Cochrane, Allied and Complementary Medicine (AMED), The National Center for Complementary and Alternative Medicine (NCCAM), and China National Knowledge Infrastructure (CNKI) databases to identify relevant monographs and related references from 1991 to 2013. Chinese journals and theses/dissertations were hand searched. Results. 47 studies were recruited and divided into 6 groups by measuring tools, that is, MRI, in vivo evaluation, CT, ultrasound, dissected specimen of cadavers, and another group with clinical efficacy. Each research was analyzed for study design, definition of safe depth, and factors that would affect the measured depths. Depths of clinical efficacy were discussed from the perspective of de-qi and other clinical observations. Conclusions. Great inconsistency in depth of each point measured from different subject groups and tools exists. The definition of safe depth should be established through standardization. There is also lack of researches to compare the clinical efficacy. A well-designed clinical trial selecting proper measuring tools to decide the actual and advisable needling depth for each point, to avoid adverse effects or complications and promote optimal clinical efficacy, is a top priority.

Outbreak of hepatitis B in a nursing home associated with capillary blood sampling

In 2001, two residents of a nursing home in Lower Saxony, Germany, were diagnosed with acute hepatitis B virus (HBV) infection. A systematic contact investigation of 188 residents yielded 19 confirmed or probable cases of acute or recent HBV infection and three persistent asymptomatic HBsAg carriers. Sequence analysis revealed that one carrier had high viraemia (109 genomes/ml), HBV genotype A2, and the same S gene and/or X gene sequence as 16 acutely infected persons. An unmatched case-control study was conducted with the 17 cases that had sequence identity together with 26 controls. The strongest association was found for treatment by a particular general practitioner (GP) (OR > 11, P < 0.001) and blood sampling for glucose monitoring on a particular day by the GP's staff (OR 13.6, P < 0.001, adjusted OR 8.5, P = 0.017). Control measures were implemented. Serological controls after 6 and 18 months revealed that the outbreak was brought under control.

An outbreak of post-acupuncture cutaneous infection due to Mycobacterium abscessus

Background

Despite the increasing popularity of acupuncture, the importance of infection control is not adequately emphasized in Oriental medicine. In December 2001, an Oriental medical doctor in Seoul, South Korea, encountered several patients with persistent, culture-negative skin lesions on the trunk and extremities at the sites of prior acupuncture treatment. We identified and investigated an outbreak of Mycobacterium abscessus cutaneous infection among the patients who attended this Oriental medicine clinic.

Methods

Patients were defined as clinic patients with persistent cutaneous infections at the acupuncture sites. Medical records for the previous 7 months were reviewed. Clinical specimens were obtained from the patients and an environmental investigation was performed. M. abscessus isolates, cultured from patients, were compared by pulsed-field gel electrophoresis (PFGE).

Results

Forty patients who attended the Oriental medicine clinic and experienced persistent cutaneous wound infections were identified. Cultures from five of these patients proved positive, and all other diagnoses were based on clinical and histopathologic examinations. All environmental objects tested were negative for M. abscessus, however, most were contaminated by various nosocomial pathogens. Molecular analysis using PFGE found all wound isolates to be identical.

Conclusion

We have identified a large outbreak of rapidly growing mycobacterial infection among patients who received acupuncture at a single Oriental medicine clinic. Physicians should suspect mycobacterial infections in patients with persistent cutaneous infections following acupuncture, and infection control education including hygienic practice, should be emphasized for Oriental medical doctors practicing acupuncture.

Is acupuncture a risk factor for hepatitis? Systematic review of epidemiological studies

OBJECTIVE

Acupuncture has been repeatedly associated with infectious hepatitis. The aim of the present systematic review was therefore to critically evaluate such data from epidemiological investigations.

METHODS

Four independent literature searches were carried out to identify all epidemiological evidence linking acupuncture with hepatitis. All studies were validated by the authors and data extracted according to predefined criteria.

RESULTS

Fifteen investigations fulfilled our inclusion criteria. Most studies originated from Asia. One study included markers to hepatitis A virus, three to hepatitis B virus, and 13 to hepatitis C virus. Five investigations reported associations between acupuncture and seropositivity to hepatitis C virus. In those studies, acupuncture increased the risk only modestly.

CONCLUSION

A modest association between hepatitis C and acupuncture has been reported in some countries. This emphasizes the importance of exclusively using disposable acupuncture needles.

Side-effects of complementary and alternative medicine

Complementary and alternative medicine are increasingly used to diagnose or treat allergic diseases, and numerous studies have reported benefits of this type of medicine. This article presents a review of the literature on risks of these methods. The potential sensitizing capacity of numerous herbal remedies may lead to allergic contact dermatitis and more rarely to IgE-mediated clinical symptoms. Mechanical injuries may be observed following acupuncture leading to pneumothorax, cardiac tamponade or spinal injury. Infectious complications after acupuncture include hepatitis and bacterial endocariditis. Organ toxicity has been observed associated with various herbal preparations involving the liver, kidneys, and the heart. Some herbs may have cancerogenic properties. Severe nutritional deficiencies can occur in infants and small children given strict alternative diets, resembling 'kwashiorkor'. Finally, among other miscellaneous adverse effects, adulteration with steroids, and herbal and drug interactions are discussed. The pattern of side-effects is similar to that observed by the use of conventional medicine. Therefore, caution may be justified using both conventional and unconventional methods. Only if the benefit is proven and the side-effects are established, should a given method be chosen.

Control of infection in acupuncture

This paper is an update on infections, and potential infections, related to acupuncture, and a brief review of the relevant infection control procedures. There is no evidence at present to suggest that significant numbers of infections are being transmitted through standard acupuncture treatments in the UK. None the less, good infection control is essential. Like any other science, new research forces infection control to evolve and refine its procedures. Acupuncturists need to constantly review their standards as new viruses and risks are identified.

Survey of infection control procedures at manicure and pedicure establishments in North York

OBJECTIVE

To describe infection control practices used by technicians doing manicures and pedicures in an urban setting in Ontario.

METHODS

A random sample of 120 establishments was selected from a sampling frame. A survey was designed and administered to technicians through face-to-face interviews.

RESULTS

Technicians in 72 establishments were interviewed, representing a 60% response rate. Twenty-nine (40%) of these technicians indicated that they had been immunized against hepatitis B. Technicians re-used almost all instruments even if this was not the intent of the manufacturer. Isopropyl alcohol was the most commonly used disinfectant. Many technicians did not wear gloves while performing procedures. Most did not follow universal precautions when asked how they would react to incidental cuts on either the client or themselves.

CONCLUSION

There is a need for the development of infection control protocols for manicure and pedicure establishments since the potential for transmission of infectious diseases does exist.

Adverse events of acupuncture and occlusal splint therapy in the treatment of craniomandibular disorders

Occlusal splint therapy and acupuncture have been found to provide positive treatment in a number of studies. As with other therapies, adverse events may occur. In this paper, adverse event refers to any reaction to a treatment besides the intended treatment effect--irrespective of any correlation between the treatment and the reaction. This reaction can be positive, as well as negative, to the patient. In the present study, 61 patients with craniomandibular dysfunction (CMD) were treated with acupuncture or occlusal splint therapy and the adverse events were carefully recorded. The results show that the profile of the adverse events differed between the two treatment modes. Acupuncture seemed to have adverse events of a more general nature, e.g., relaxed feeling, improved sleep, temporarily increased pain; whereas, adverse events of occlusal splint therapy seemed to be more locally related to the orofacial region, e.g., increased/decreased salivation and tension in the teeth. The majority of the patients responded positively to both treatment modalities. Only in a few cases did the patients consider the treatment uncomfortable. No serious adverse event or complication was observed in this study.
