Abstract
Nail cosmetics industry is growing at an enormous rate globally due to a surge in nail care all around the world. Various nail cosmetics are available, such as nail polish along with its variants like shellacs, finishes, artificial nails, adornments, and nail polish removers. Nail cosmetics serve aesthetic as well as therapeutic purposes, with the end result being smooth, attractive nails. Nail grooming procedures have evolved from a basic manicure to many other advanced procedures like gel nails, nail tattooing, etc. Although a majority of nail cosmetics are considered safe, they may have potential complications, including allergic and irritant reactions, infections, and mechanical effects. The majority of the procedures related to nail enhancement are not performed by dermatologists but by beauticians with inadequate or no knowledge of the nail's anatomy and functions. The hygiene at the so-called nail-salons/beauty parlours is not standardized, leading to acute complications like paronychia and nail dystrophy following matrix injury. The use of nail cosmetics has become widespread, making it essential for dermatologists to be aware of the nail care products, aesthetic procedures pertaining to nails, and related adverse effects.

Abstract
The main objective of this review is to identify the most frequently isolated bacteria in patients with infections related to nipple piercings in case reports and case series. In addition, the aim is to describe clinical manifestations and antecedents. There is a protocol of this review. The terms "bacterial infections", "nipple piercing" and their synonyms were considered. Pubmed/Medline, Scopus, Embase, Web of Science core collection and Ovid/Medline databases were searched until November 15, 2021 without date or language restrictions. Two authors extracted the articles and three other authors performed the selection, first by title and abstract, and second by full-text revision. Discrepancies were resolved with yet two other authors. Quality was assessed using the Joanna Briggs checklists. Finally, data extraction was realized. A total of 1,531 articles were extracted, of which 20 articles were included, and one article was added by hand-searching. The final number of articles included was 21, all of them with acceptable quality of evidence. Twenty-seven patients were considered (23 women and 4 men), aged between 15-60 years old. The most frequent bacterial genus in case reports and case series was Staphylococcus (n=10), and the most frequent species was M. fortuitum (n=6), although etiology seems to be diverse. The breast was the main affected organ, and the most frequent findings were fluid collection, pain, erythema, granulation tissue and swelling. The suspicion of infection by this bacterial species could be taken into account when it is associated with nipple piercings; however, larger studies are required to give a conclusion based on the evidence.

Abstract
RATIONALE Mycobacterium peregrinum is a member of the group of rapidly growing nontuberculous mycobacteria. It mainly causes surgical site and catheter-related infections, while pulmonary infection is rare. We herein present a case of pulmonary infection caused by M peregrinum. PATIENT CONCERNS A 62-year-old woman visited our hospital with dyspnea and was admitted for the treatment of pneumonia in July 2018. DIAGNOSIS Chest computed tomography showed patchy opacities and consolidation in the bilateral lungs and a cavity in the right upper lobe, which persisted after the treatment of bacterial pneumonia 5 years ago. She was administered ceftriaxone and azithromycin. Consolidation in the bilateral lungs improved, whereas the cavity in the right upper lobe remained and the consolidation surrounding it gradually spread. On admission, the sputum acid-fast bacillus culture was positive, and M peregrinum was identified twice by mass spectrometry. The cavity and consolidation surrounding it were diagnosed as pulmonary mycobacteriosis caused by M peregrinum. INTERVENTIONS Although we recommended treatment for mycobacteriosis, the patient refused it. OUTCOMES The patient is regularly followed up; however, the cavity wall is thickening and shadows have become mildly enhanced over the course of 3 years. LESSONS We herein present a rare case of pulmonary mycobacteriosis caused by M peregrinum and discuss the literature. Since limited information is currently available on pulmonary mycobacteriosis caused by M peregrinum, the accumulation of further case reports and the clarification of its clinical features are needed.

Abstract
Mycobacterium chelonae infections involving the lower extremities are rare clinical entities that present a diagnostic challenge given its diverse clinical presentations ranging from superficial (e.g., cellulitis, painful vesicular lesions) to deep (e.g., tenosynovitis) infections. We present 1 cases of M chelonae infections of the feet diagnosed 6 to 12 months after initial symptoms representing the difficulty of diagnosing this condition. Both cases were successfully managed with aggressive surgical debridement and long durations of antibiotic therapy with long-term care. A comprehensive review of the literature of M chelonae infections of the lower extremities was performed to provide summary data on the presenting symptoms, examination findings, predisposing conditions, and management approaches of this rare, but emerging clinical entity. Our cases and comprehensive review serve to raise awareness of atypical mycobacterial infections, including M chelonae, and advocate for the early consideration of mycobacterial cultures in the diagnostic workup of chronic lower extremity infections especially in the setting of poor initial response to standard antibacterial therapies.

Abstract
Since nontuberculous mycobacteria (NTM) are pervasive in the environment and NTM infections are relatively uncommon, underlying hereditary or acquired host susceptibility factors should be sought for in most NTM-infected patients. To facilitate identification of underlying risk factors, it is useful to classify NTM disease into skin-soft tissue infections, isolated NTM lung disease, and extrapulmonary viscera-disseminated disease because the latter two categories have unique sets of underlying host risk factors.

Identification of Nontuberculous Mycobacteria in Patients with Pulmonary Diseases in Gyeongnam, Korea, Using Multiplex PCR and Multigene Sequence-Based Analysis. ACTA ACUST UNITED AC 2021; 2021:8844306. [PMID: 33688383 PMCID: PMC7920741 DOI: 10.1155/2021/8844306] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/28/2020] [Revised: 01/27/2021] [Accepted: 02/08/2021] [Indexed: 11/18/2022]
Abstract
Background Nontuberculous mycobacteria (NTM) are widely present in environments, such as soil and water, and have recently been recognized as important pathogenic bacteria. The incidence of NTM-related infections is steadily increasing. As the diagnosis and treatment of NTM infection should be distinguished from tuberculosis, and the treatment should be specific to the species of NTM acquired, accurate species identification is required. Methods In this study, two-step multiplex PCR (mPCR) and multigene sequence-based analysis were used to accurately identify NTM species in 320 clinical isolates from Gyeongsang National University Hospital (GNUH). In particular, major mycobacterial strains with a high isolation frequency as well as coinfections with multiple species were diagnosed through two-step mPCR. Multigene sequencing was performed to accurately identify other NTM species not detected by mPCR. Variable regions of the genes 16S rRNA, rpoB, hsp65, and 16S-23S rRNA internal transcribed spacer were included in the analysis. Results Two-step mPCR identified 234 (73.1%) cases of M. intracellulare, 26 (8.1%) cases of M. avium subsp. avium, and 13 (4.1%) cases of M. avium subsp. hominissuis infection. Additionally, 9 (2.8%) M. fortuitum, 9 (2.8%) M. massiliense, 2 (0.6%) M. abscessus, and 4 (1.2%) M. kansasii isolates were identified. Coinfection was identified in 7 (2.2%) samples. The sixteen samples not classified by two-step mPCR included 6 (1.9%) cases of M. chimaera, 4 (1.3%) M. gordonae, 1 (0.3%) M. colombiense, 1 (0.3%) M. mageritense, and 1 (0.3%) M. persicum identified by sequence analysis. Conclusions The results of this study suggest a strategy for rapid detection and accurate identification of species using two-step mPCR and multigene sequence-based analysis. To the best of our knowledge, this study is the first to report the identification of NTM species isolated from patients in Gyeongnam/Korea.

Abstract
Kaposi sarcoma inflammatory cytokine syndrome is a rare and fatal malignancy that is challenging to treat. The syndrome appears in individuals who are both human immunodeficiency virus and human herpesvirus 8 positive. The diagnosis of disease is challenging because its presentation mimics sepsis and it has a high mortality rate. A bone marrow biopsy is necessary for definitive diagnosis. This case report discusses a 40-year-old human immunodeficiency virus infection-positive African American male who presented to the emergency department with a chief complaint of left hallux pain in January 2018 after a trip to a nail salon in December 2017. Radiographic and magnetic resonance images suggested osteomyelitis of the distal phalanx, and Gram stain of bone showed gram-negative rods. The patient was started on antibiotic therapy for presumed osteomyelitis. As the patient's status deteriorated, a partial hallux amputation was then performed. Intraoperative specimens were negative for bacterial involvement, but pathology was positive for Kaposi sarcoma. During a 7-month progression, the patient's hematologic and overall status continued to decline. Despite diagnostic and treatment guidelines being followed, the patient died from this illness in July 2018. This case is interesting because of the atypical presentation of Kaposi sarcoma and highlights the rapid progression of the disease.

Pulmonary infection due to fluoroquinolone-resistant Mycolicibacterium fortuitum: a case report. BMC Infect Dis 2020; 20:866. [PMID: 33213390 PMCID: PMC7678322 DOI: 10.1186/s12879-020-05596-1] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/03/2020] [Accepted: 11/05/2020] [Indexed: 01/21/2023] Open
Abstract
Background Mycolicibacterium fortuitum is a species of the rapidly growing mycobacteria that can cause pulmonary infection. It is susceptible to multiple antibiotics both in vitro and in clinical practice, so that any combination of susceptible drugs is effective. However, we encountered a case of infection due to fluoroquinolone-resistant M. fortuitum. In this study, we report the case and describe the mechanism of resistance. Case presentation A 65-year-old man with a history of total gastrectomy and immunosuppressant treatment for rheumatoid arthritis developed a recurrence of pulmonary infection caused by M. fortuitum. He was treated with clarithromycin and levofloxacin as a first-line treatment, based on the favorable susceptibility at that time. After recurrence, a high minimum inhibitory concentration to fluoroquinolones was detected. DNA sequencing of the pathogen showed the substitution of serine for tryptophan at residue 83 in the gyrA gene. He was successfully treated with a combination of other antibiotics. Conclusion This is the first report on the treatment of fluoroquinolone-resistant M. fortuitum and investigation of the mechanism of resistance. We suggest that the susceptibility test remains effective for determining the next line of treatment after a pathogen has acquired resistance, and resistance to fluoroquinolones in M. fortuitum can be attributed to a single change of amino acid.

Abstract
BACKGROUND Nontuberculous mycobacteria (NTM) lymphadenitis is an under-recognized entity, and data of the true burden in children are limited. Without a high index of suspicion, diagnosis may be delayed and microbiological detection is challenging. Here, we report a cluster of NTM lymphadenitis experienced in Korean children. METHODS Subjects under 19 years of age diagnosed with NTM lymphadenitis during November 2016-April 2017 and April 2018 were included. Electronic medical records were reviewed for clinical, laboratory and pathological findings. Information regarding underlying health conditions and environmental exposure factors was obtained through interview and questionnaires. RESULTS A total of ten subjects were diagnosed during 18 months. All subjects were 8-15 years of age, previously healthy, male and had unilateral, nontender, cervicofacial lymphadenitis for more than 3 weeks with no significant systemic symptoms and no response to empirical antibiotics. Lymph nodes involved were submandibular (n = 8), preauricular (n = 6) and submental (n = 1). Five patients had two infected nodes and violaceous discoloration was seen in seven subjects. Biopsy specimens revealed chronic granulomatous inflammation and acid-fast bacteria culture identified Mycobacterium haemophilum in two cases and NTM polymerase chain reaction was positive in two cases. Survey revealed various common exposure sources. CONCLUSION NTM lymphadenitis is rare but increasing in detection and it may occur in children and adolescents. Diagnosis requires high index of suspicion and communication between clinicians and the laboratory is essential for identification of NTM.

Abstract
Although less common as causes of musculoskeletal infection than pyogenic bacteria, both Mycobacterium tuberculosis and nontuberculous mycobacteria can infect bones and joints. Although tuberculous arthritis and osteomyelitis have been recognized for millennia, infections caused by nontuberculous mycobacteria are being identified more often, likely because of a more susceptible host population and improvements in diagnostic capabilities. Despite advances in modern medicine, mycobacterial infections of the musculoskeletal system remain particularly challenging to diagnose and manage. This article discusses clinical manifestations of musculoskeletal infections caused by Mycobacterium tuberculosis and nontuberculous mycobacteria. Pathogenesis, unique risk factors, and diagnostic and therapeutic approaches are reviewed.

Abstract
Background Personal services is a continuously evolving industry that encompasses a variety of aesthetic treatments and personal enhancement services. Personal services are an important public health concern because delivery of service may pose potential health risks for both clients and workers. To date, there is a lack of evidence on the specific infection risks involved with personal services and the magnitude of these risks. While guidance and regulation of personal services settings do exist, they appear in varying degrees and complexity across Canada. Objectives To summarize relevant literature on the risk of infections related to personal services; conduct an environmental scan of current provincial and territorial guidance and regulations; identify key risk mitigation measures; and summarize gaps and challenges. Methods A working group of national experts in the field was established for consultation on key issues. A narrative literature review was conducted to summarize findings from relevant articles. Key questions and a literature search strategy were developed and articles were screened and critically appraised for eligibility. An environmental scan of key guidelines was also conducted to identify relevant legislation and guidance. Findings from both the narrative review and environmental scan were summarized to inform guidance and identify gaps. Findings The review of the literature identified factors associated with increased risk of infection including inadequate training of personal services workers and non-compliance with established infection prevention principles. The environmental scan demonstrated that some guidelines have been developed by provincial/territorial ministries of health utilizing basic, generally accepted infection prevention principles. The established body of evidence that informs infection prevention and control recommendations is valid for health care settings; however there are factors to consider in extracting and applying such guidance to personal services settings. Major gaps and challenges remain in supporting both the advancement of infection prevention guidance and the development of enhanced regulatory frameworks, applicable to personal services settings in Canada. Conclusion This review involved a comprehensive examination of relevant literature and provides a summary of issues addressing the risk of infection in personal services settings. There is a paucity of high quality evidence to support guidance, and findings reveal the need for further investigation and enhanced awareness of public health risks associated with personal services. Nonetheless, these findings can inform future research and the development of infection prevention and control guidelines and recommendations for such settings.

Abstract
Nontuberculous mycobacteria (NTM) diseases mainly manifest as pulmonary illnesses, but 20 -30% of NTM isolates originate from extrapulmonary diseases. These diseases cause a variety of clinical syndromes, including skin and soft-tissue infections, musculoskeletal infections, lymphadenitis, and disseminated disease. In skin and soft-tissue infections, musculoskeletal infections, prolonged treatment with combinations of antibiotics is effective in the treatment of NTM diseases, with surgery as an important complementary tool. The recommended duration of therapy for skin and soft-tissue infection is usually 2 – 4 months for mild disease and 6 months for severe disease, while treatment of musculoskeletal NTM disease usually requires at least 6 - 12 months. Management options of NTM lymphadenitis include surgical intervention, medical therapy, or observation. Treatment of disseminated NTM disease generally requires 6 to 12 months after immune restoration. However, despite a considerable increase in knowledge about NTM diseases, determining optimal treatment approaches remains a complex and challenging task.

Abstract
Objective To understand factors associated with community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) acquisition and infection, we mapped public places (including personal service establishments, fitness centers, pools, schools, and daycares) visited by members of households affected by CA-MRSA skin and soft tissue infection. Results From January 2012 to October 2015, households of children with CA-MRSA SSTI in metropolitan St. Louis were enrolled in the HOME: Household Observation of MRSA in the Environment study. Addresses of public places visited within 3 months of enrollment were reported by 671 participants and were analyzed using a geographic information system (GIS). The Nearest Neighbor Tool in ArcGIS assessed clustering of public places within the study region. Public places were significantly clustered within the study area compared to the expected distance between locations (p < 0.001). Additionally, one-third (48/150) of participating households visited at least one public place in common with other households. No significant relationship between participants visiting the public places within 3 months of enrollment and subsequent colonization or SSTI were found. Understanding community behavior is critical to informing public health initiatives to reduce the prevalence of CA-MRSA infections.

Abstract
Nontuberculous mycobacteria (NTM), ubiquitous in soil and water, usually infect immunocompromised persons. However, even healthy persons are susceptible to infection through percutaneous inoculation. Although 77% of NTM diseases manifest as primarily pulmonary illnesses (1), NTM also infect skin, bones, joints, the lymphatic system, and soft tissue. NTM infections can have incubation periods that exceed 5 years (2), often require prolonged treatment, and can lead to sepsis and death. Extrapulmonary NTM outbreaks have been reported in association with contaminated surgical gentian violet (3), nail salon pedicures (4), and tattoos received at tattoo parlors (5), although few surveillance data have been available for estimating the public health burden of NTM.* On January 1, 2014, the Oregon Health Authority designated extrapulmonary NTM disease a reportable condition. To characterize extrapulmonary NTM infection, estimate resources required for surveillance, and assess the usefulness of surveillance in outbreak detection and investigation, 2014–2016 extrapulmonary NTM surveillance data were reviewed, and interviews with stakeholders were conducted. During 2014–2016, 134 extrapulmonary NTM cases (11 per 1 million persons per year) were reported in Oregon. The age distribution was bimodal, with highest incidence among persons aged <10 years (20 per 1 million persons per year) and persons aged 60–69 years (18 per 1 million persons per year). The most frequently reported predisposing factors (occurring within 14–70 days of symptom onset) were soil exposure (41/98; 42%), immunocompromised condition (42/124; 34%), and surgery (32/120; 27%). Overall, 43 (33%) patients were hospitalized, 18 (15%) developed sepsis, and one (0.7%) died. Surveillance detected or helped to control two outbreaks at low cost. Jurisdictions interested in implementing extrapulmonary NTM surveillance can use the Council of State and Territorial Epidemiologists (CSTE) standardized case definition (6) for extrapulmonary NTM reporting or investigative guidelines maintained by the Oregon Health Authority (7).

Abstract
Limited data are available describing extrapulmonary nontuberculous mycobacteria (NTM) infections in the general population. We describe results from statewide population-based laboratory surveillance in Oregon, USA, during 2007–2012. We defined a case of extrapulmonary NTM infection as >1 isolate from skin/soft tissue, disseminated sites, lymph node, joint, or other sites. The annual incidence of extrapulmonary NTM infection (other than Mycobacterium gordonae) was stable, averaging 1.5 cases/100,000 population. Median age of the 334 patients was 51 years, and 53% of patients were female. Half of cases were caused by M. avium complex, but rapid-growing NTM species accounted for one third of cases. Most extrapulmonary NTM infections are skin/soft tissue. Compared with pulmonary NTM infection, more extrapulmonary infections are caused by rapid-growing NTM species. the designation of NTM as a reportable disease in Oregon in 2014 will result in better detection of changes in the incidence and patterns of disease in the future.

Abstract
Nontuberculous mycobacteria (NTM) include species that colonize human epithelia, as well as species that are ubiquitous in soil and aquatic environments. NTM that primarily inhabit soil and aquatic environments include the Mycobacterium avium complex (MAC, M. avium and Mycobacterium intracellulare) and the Mycobacterium abscessus complex (MABSC, M. abscessus subspecies abscessus, massiliense, and bolletii), and can be free-living, biofilm-associated, or amoeba-associated. Although NTM are rarely pathogenic in immunocompetent individuals, those who are immunocompromised - due to either an inherited or acquired immunodeficiency - are highly susceptible to NTM infection (NTMI). Several characteristics such as biofilm formation and the ability of select NTM species to form distinct colony morphotypes all may play a role in pathogenesis not observed in the related, well-characterized pathogen Mycobacterium tuberculosis The recognition of different morphotypes of NTM has been established and characterized since the 1950s, but the mechanisms that underlie colony phenotype change and subsequent differences in pathogenicity are just beginning to be explored. Advances in genomic analysis have led to progress in identifying genes important to the pathogenesis and persistence of MAC disease as well as illuminating genetic aspects of different colony morphotypes. Here we review recent literature regarding NTM ecology and transmission, as well as the factors which regulate colony morphotype and pathogenicity.

Abstract
Nontuberculous mycobacteria (NTM) are environmental pathogens that are an increasingly common cause of pulmonary and extrapulmonary disease. Electronic laboratory-based reporting is a straightforward mechanism for identifying NTM infections and for monitoring trends in disease. Oregon was the first state to make NTM reportable, although at this time the reporting requirement is limited to extrapulmonary infection. This has assisted authorities in detecting outbreaks and healthcare-related infections. However, further consideration should be given to the reportability of pulmonary NTM disease. Pulmonary NTM disease is more common than tuberculosis in the United States and is of emerging public health concern. Although the direct public health action that would be triggered by a pulmonary NTM disease report is not clear, without surveillance, public health is missing an opportunity to better understand pulmonary NTM disease trends and reasons for its increasing recognition within our population. We believe state health authorities should conduct surveillance for pulmonary NTM, either by mandating reporting of laboratory isolates or by other mechanisms as we have done in Oregon.

Abstract
The genus Mycobacterium includes human pathogens (Mycobacterium tuberculosis and Mycobacterium leprae) and environmental organisms known as non-tuberculous mycobacteria (NTM) that, when associated with biomaterials and chronic disease, can cause human infections. A common pathogenic factor of mycobacteria is the formation of biofilms. Various molecules are involved in this process, including glycopeptidolipids, shorter-chain mycolic acids, and GroEL1 chaperone. Nutrients, ions, and carbon sources influence bacterial behavior and have a regulatory role in biofilm formation. The ultrastructure of mycobacterial biofilms can be studied by confocal laser scanning microscopy, a technique that reveals different phenotypic characteristics. Cording is associated with NTM pathogenicity, and is also considered an important property of M. tuberculosis strains. Mycobacterial biofilms are more resistant to environmental aggressions and disinfectants than the planktonic form. Biofilm-forming mycobacteria have been reported in many environmental studies, especially in water systems. NTM cause respiratory disease in patients with underlying diseases, such as old tuberculosis scars, bronchiectasis, and cystic fibrosis. Pathogens can be either slowly growing mycobacteria, such as Mycobacterium avium complex, or rapidly growing species, such as Mycobacterium abscessus. Another important biofilm-related group of infections are those associated with biomaterials, and in this setting the most frequently isolated organisms are rapidly growing mycobacteria. M. tuberculosis can develop a biofilm which plays a role in the process of casseous necrosis and cavity formation in lung tissue. M. tuberculosis also develops biofilms on clinical biomaterials. Biofilm development is an important factor for antimicrobial resistance, as it affords protection against antibiotics that are normally active against the same bacteria in the planktonic state. This antibiotic resistance of biofilm-forming microorganisms may result in treatment failure, and biofilms have to be physically eradicated to resolve the infection. New strategies with potential antibiofilm molecules that improve treatment efficacy have been developed. A novel antibiofilm approach focuses on Methylobacterium sp. An understanding of biofilm is essential for the appropriate management of patients with many NTM diseases, while the recent discovery of M. tuberculosis biofilms opens a new research field.

Abstract
This chapter is unique in its focus on infections that are acquired in water. For those who like to swim and spend time in water parks and pools, the exposure to water and therefore the risk of infection is higher. Recreational water illnesses are illnesses related to recreation in water. Of these recreational water illnesses, infections are the most common because water laden with microorganisms or contaminated by human activity gains access to healthy tissue through the skin and body orifices. Infection occurs by inhalation, ingestion, or direct invasion of the respiratory and gastrointestinal tract. Gastrointestinal infections are the most common. This chapter discusses skin and soft tissue infections, ocular infections, urinary tract infections, pulmonary infections, central nervous system infections, and disseminated infections that can occur as people come into contact with natural nonmarine water bodies as well as manmade aquatic environments. Most of these infections are mild but can occasionally be life threatening. There is a focus on the latest methods to treat these infections. Pseudomonas aeruginosa is a very common pathogen in water. The chapter discusses P. aeruginosa dermatitis at length and also looks at keratitis and pneumonia caused by this organism. The chapter also discusses the latest treatments for primary amoebic meningoencephalitis, a severe life-threatening illness with a high mortality, caused by Naegleria fowleri. Finally, there is an in-depth discussion of the notorious gastrointestinal illnesses such as norovirus and Cryptosporidium parvum that can affect large numbers of people at a time.

Abstract
Background Nontuberculous mycobacteria (NTM) commonly colonize municipal water supplies and cause healthcare-associated outbreaks. We investigated a biphasic outbreak of Mycobacterium abscessus at a tertiary care hospital. Methods Case patients had recent hospital exposure and laboratory-confirmed colonization or infection with M. abscessus from January 2013 through December 2015. We conducted a multidisciplinary epidemiologic, field, and laboratory investigation. Results The incidence rate of M. abscessus increased from 0.7 cases per 10000 patient-days during the baseline period (January 2013-July 2013) to 3.0 cases per 10000 patient-days during phase 1 of the outbreak (August 2013-May 2014) (incidence rate ratio, 4.6 [95% confidence interval, 2.3-8.8]; P < .001). Thirty-six of 71 (51%) phase 1 cases were lung transplant patients with positive respiratory cultures. We eliminated tap water exposure to the aerodigestive tract among high-risk patients, and the incidence rate decreased to baseline. Twelve of 24 (50%) phase 2 (December 2014-June 2015) cases occurred in cardiac surgery patients with invasive infections. Phase 2 resolved after we implemented an intensified disinfection protocol and used sterile water for heater-cooler units of cardiopulmonary bypass machines. Molecular fingerprinting of clinical isolates identified 2 clonal strains of M. abscessus; 1 clone was isolated from water sources at a new hospital addition. We made several water engineering interventions to improve water flow and increase disinfectant levels. Conclusions We investigated and mitigated a 2-phase clonal outbreak of M. abscessus linked to hospital tap water. Healthcare facilities with endemic NTM should consider similar tap water avoidance and engineering strategies to decrease risk of NTM infection.

Abstract
Rapidly growing nontuberculous mycobacteria (RG-NTM), which can contaminate inadequately sterilized medical instruments, have been known to cause serious postsurgical skin and soft tissue infections that often are characterized by a prolonged incubation period and a disfiguring clinical course. Historically, these infections have been associated with surgical procedures performed outside the United States. The Centers for Disease Control and Prevention recently reported an outbreak of RG-NTM infections among women who underwent cosmetic surgery in the Dominican Republic. Because of the large Dominican American community in upper Manhattan, we have recently observed a number of these cases at NewYork-Presbyterian Hospital/Columbia University Medical Center. We highlight the case of a 55-year-old woman who developed a postsurgical RG-NTM infection after bilateral breast reduction in the Dominican Republic; she experienced progressive deformity of her left breast until the causative pathogen was identified 20 months after her initial surgery. To assist in the timely diagnosis and treatment of these infections, we aim to promote greater awareness among physicians who are likely to encounter such patients. We present the pathologic findings of a review of 7 cases of RG-NTM infections seen at NewYork-Presbyterian Hospital/Columbia University Medical Center and discuss the diagnostic and therapeutic challenges associated with these infections, such as prolonged incubation periods, the need for acid-fast stains and mycobacterial cultures, and the combination of surgical therapy and lengthy antibiotic courses that are often required for treatment.

Abstract
The aim of this study was to investigate the serological and molecular prevalence of hepatitis B virus (HBV) infection in 514 manicurists/pedicurists and identify the risk factors related with this infection. Samples were tested for HBV serological markers, hepatitis C virus (HCV), and human immunodeficiency virus (HIV) by enzyme-linked immunosorbent assay (ELISA). Anti-HBc-positive samples were tested to investigate occult hepatitis B by PCR. HBsAg-positive samples were genotyped and the viral loads of HBV-DNA positive samples were quantified. The overall HBV prevalence was 5.6% (29/514) and of HBsAg was 0.4% (2/514). One case of occult hepatitis B was found. The genotypes A1 and F2 were identified in two HBsAg-positive samples. Low level of education, not being born in the State of Mato Grosso do Sul and working in the central region of the city were associated with the HBV infection. No single manicurist/pedicurist was infected by HCV or HIV. These findings suggest that despite the exposure to blood contact, this occupation was not associated to an increased risk of acquiring HBV, HCV, and HIV infections.

Abstract
Dermatologically relevant nontuberculous mycobacteria (NTM) include Mycobacterium marinum and Mycobacterium ulcerans and different rapidly growing mycobacteria (RGM). RGM are widely present in the environment and are facultative pathogenic. Diagnostic detection of nontuberculous mycobacteria is frequently challenging. Immune-competent individuals mostly develop localized infections. Immune-suppressed patients may present with severe and disseminated disease. In these cases, rapid initiation of medical treatment is important. Moreover, infections with the more aggressive Mycobacterium ulcerans should be treated early. Due to the risk for the development of inducible antibiotic resistance, antibiotic regimes for NTM infections typically require at least two drugs. Surgical treatment should also be considered. This article discusses clinical presentation, diagnostic workup, and in particular antibiotic treatment options for dermatologically relevant infections caused by NTM.

Abstract
Although less common as causes of musculoskeletal infection than pyogenic bacteria, both Mycobacterium tuberculosis and nontuberculous mycobacteria can infect bones and joints. Although tuberculous arthritis and osteomyelitis have been recognized for millennia, infections caused by nontuberculous mycobacteria are being identified more often, likely because of a more susceptible host population and improvements in diagnostic capabilities. Despite advances in modern medicine, mycobacterial infections of the musculoskeletal system remain particularly challenging to diagnose and manage. This article discusses clinical manifestations of musculoskeletal infections caused by Mycobacterium tuberculosis and nontuberculous mycobacteria. Pathogenesis, unique risk factors, and diagnostic and therapeutic approaches are reviewed.

[PMID: 28131606 DOI: 10.1016/j.ijantimicag.2016.10.024] [Citation(s) in RCA: 29] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/15/2016] [Revised: 09/28/2016] [Accepted: 10/01/2016] [Indexed: 10/20/2022]
Abstract
To treat nontuberculous mycobacteria (NTM) infections more optimally, further research pertaining to mycobacterial susceptibility to antimicrobial agents is required. A total of 82 species of NTM reference strains and 23 species of NTM clinical isolates were included. Minimum inhibitory concentrations (MICs) for 41 drugs were determined using the microdilution method in cation-adjusted Mueller-Hinton broth. The results showed that most of the NTM were susceptible to aminoglycosides, quinolones, three macrolides (clarithromycin, azithromycin and roxithromycin), cefmetazole, linezolid and capreomycin. Rapidly growing mycobacterium strains were additionally susceptible to cefoxitin, clofazimine, rifapentine, doxycycline, minocycline, tigecycline, meropenem and sulfamethoxazole, whereas slowly growing mycobacterium strains were additionally susceptible to rifabutin. This study on the susceptibility of NTM includes the largest sample size of Chinese clinical isolates and reference strains. NTM species-specific drug susceptibility patterns suggested that it is urgent to identify the species of NTM, to normalise the treatment of NTM infectious disease and to clarify the resistance mechanisms of NTM.

Abstract
Molecular typing has revolutionized epidemiological studies of infectious diseases, including those of a mycobacterial etiology. With the advent of fingerprinting techniques, many traditional concepts regarding transmission, infectivity, or pathogenicity of mycobacterial bacilli have been revisited, and their conventional interpretations have been challenged. Since the mid-1990s, when the first typing methods were introduced, a plethora of other modalities have been proposed. So-called molecular epidemiology has become an essential subdiscipline of modern mycobacteriology. It serves as a resource for understanding the key issues in the epidemiology of tuberculosis and other mycobacterial diseases. Among these issues are disclosing sources of infection, quantifying recent transmission, identifying transmission links, discerning reinfection from relapse, tracking the geographic distribution and clonal expansion of specific strains, and exploring the genetic mechanisms underlying specific phenotypic traits, including virulence, organ tropism, transmissibility, or drug resistance. Since genotyping continues to unravel the biology of mycobacteria, it offers enormous promise in the fight against and prevention of the diseases caused by these pathogens. In this review, molecular typing methods for Mycobacterium tuberculosis and nontuberculous mycobacteria elaborated over the last 2 decades are summarized. The relevance of these methods to the epidemiological investigation, diagnosis, evolution, and control of mycobacterial diseases is discussed.

Abstract
Background: Cutaneous atypical mycobacterial infections have been increasingly described in association with cosmetic and alternative procedures. Objective: We report an outbreak of acupuncture-associated mycobacteriosis. Between April and December 2002, 32 patients developed cutaneous mycobacteriosis after visiting an acupuncture practice in Toronto, Canada. Results: Of 23 patients whose lesions were biopsied, 6 (26.1%) had culture-confirmed infection with Mycobacterium abscessus. These isolates were genetically indistinguishable by amplified fragment length polymorphism. The median incubation period was 1 month. Of 24 patients for whom clinical information was available, 23 (95.8%) had resolution of their infection. All patients developed residual scarring or hyperpigmentation. Conclusion: Nontuberculous mycobacteria should be recognized as an emerging, but preventable, cause of acupuncture-associated infections.

Abstract
The 2013 Infection Prevention and Control (IP&C) Guideline for Cystic Fibrosis (CF) was commissioned by the CF Foundation as an update of the 2003 Infection Control Guideline for CF. During the past decade, new knowledge and new challenges provided the following rationale to develop updated IP&C strategies for this unique population:1.The need to integrate relevant recommendations from evidence-based guidelines published since 2003 into IP&C practices for CF. These included guidelines from the Centers for Disease Control and Prevention (CDC)/Healthcare Infection Control Practices Advisory Committee (HICPAC), the World Health Organization (WHO), and key professional societies, including the Infectious Diseases Society of America (IDSA) and the Society for Healthcare Epidemiology of America (SHEA). During the past decade, new evidence has led to a renewed emphasis on source containment of potential pathogens and the role played by the contaminated healthcare environment in the transmission of infectious agents. Furthermore, an increased understanding of the importance of the application of implementation science, monitoring adherence, and feedback principles has been shown to increase the effectiveness of IP&C guideline recommendations.2.Experience with emerging pathogens in the non-CF population has expanded our understanding of droplet transmission of respiratory pathogens and can inform IP&C strategies for CF. These pathogens include severe acute respiratory syndrome coronavirus and the 2009 influenza A H1N1. Lessons learned about preventing transmission of methicillin-resistantStaphylococcus aureus(MRSA) and multidrug-resistant gram-negative pathogens in non-CF patient populations also can inform IP&C strategies for CF.

Abstract
BACKGROUND Legionella pneumophila, Mycobacterium avium, and Pseudomonas aeruginosa are opportunistic premise plumbing pathogens (OPPPs) that persist and grow in household plumbing, habitats they share with humans. Infections caused by these OPPPs involve individuals with preexisting risk factors and frequently require hospitalization. OBJECTIVES The objectives of this report are to alert professionals of the impact of OPPPs, the fact that 30% of the population may be exposed to OPPPs, and the need to develop means to reduce OPPP exposure. We herein present a review of the epidemiology and ecology of these three bacterial OPPPs, specifically to identify common and unique features. METHODS A Water Research Foundation-sponsored workshop gathered experts from across the United States to review the characteristics of OPPPs, identify problems, and develop a list of research priorities to address critical knowledge gaps with respect to increasing OPPP-associated disease. DISCUSSION OPPPs share the common characteristics of disinfectant resistance and growth in biofilms in water distribution systems or premise plumbing. Thus, they share a number of habitats with humans (e.g., showers) that can lead to exposure and infection. The frequency of OPPP-infected individuals is rising and will likely continue to rise as the number of at-risk individuals is increasing. Improved reporting of OPPP disease and increased understanding of the genetic, physiologic, and structural characteristics governing the persistence and growth of OPPPs in drinking water distribution systems and premise plumbing is needed. CONCLUSIONS Because broadly effective community-level engineering interventions for the control of OPPPs have yet to be identified, and because the number of at-risk individuals will continue to rise, it is likely that OPPP-related infections will continue to increase. However, it is possible that individuals can take measures (e.g., raise hot water heater temperatures and filter water) to reduce home exposures.

Abstract
Laparoscopic gastric banding is a common bariatric procedure worldwide. Rapidly growing mycobacteria are environmental organisms increasingly seen as pathogens,often in infected prosthetic material. We report 18 cases of infection associated with laparoscopic gastric banding caused by Mycobacterium fortuitum and M. abscessus in Australia during 2005–2011. We identified cases by reviewing positive cultures at the Queensland state reference laboratory or through correspondence with clinicians, and we obtained clinical and epidemiologic data. Eleven cases of M. fortuitum and 7 cases of M. abscessus infection were identified. The port was thought to be the primary site of infection in 10 of these cases. Complications included peritonitis,band erosion, and chronic ulceration at the port site.Rapidly growing mycobacteria can infect both port and band and can occur as either an early perioperative or late infection.Combination antimicrobial therapy is used on the basis of in vitro susceptibilities. Device removal seems to be vital to successful therapy.

Abstract
In fish spas, clients may submerge their hands, feet or whole body in basins with Garra rufa fish, for dead skin removal. Skin infections may result from using these spas, transmitted from fish to clients, through either fish or water, or from client to client. The microbiological water quality was determined in 24 fish spas in 16 companies in the Netherlands through analysis of a single water sample per fish spa. Water samples were tested for the presence of Aeromonas spp., Vibrio spp., Pseudomonas aeruginosa, nontuberculous mycobacteria, and faecal indicator bacteria by using standard culture methods. The majority of the examined fish spas contained Aeromonas spp. (n?=?24), P. aeruginosa (n?=?18), Vibrio spp. (n?=?16) including V. cholerae non-O1/O139 and V. vulnificus, and several rapid growing Mycobacterium spp. (n?=?23) including M. fortuitum, M. conceptionense, M. abscessus and M. chelonae. Faecal contamination of the fish spa water was low. Based on the detected concentrations of Aeromonas spp., Vibrio spp., and P. aeruginosa, the detected Mycobacterium spp., and the health implications of these bacteria, the health risk from using fish spas is considered limited for healthy people with an intact skin and no underlying disease.

Abstract
: Bacterial infections following aquatic injuries occur commonly in fishermen and vacationers after freshwater and saltwater exposures. Internet search engines were queried with the key words to describe the epidemiology, clinical manifestations, diagnostic and treatment strategies and outcomes of both the superficial and the deeper invasive infections caused by more common, newly emerging and unusual aquatic bacterial pathogens. Main findings included the following: (1) aquatic injuries often result in gram-negative polymicrobial infections with marine bacteria; (2) most marine bacteria are resistant to 1st- and 2nd-generation penicillins and cephalosporins; (3) nontuberculous, mycobacterial infections should be considered in late-onset, culture-negative and antibiotic-resistant marine infections; (4) superficial marine infections and pre-existing wounds exposed to seawater may result in deeply invasive infections and sepsis in immunocompromised patients. With the exception of minor marine wounds demonstrating localized cellulitis, most other marine infections and all gram-negative and mycobacterial marine infections will require therapy with antibiotic combinations.

Abstract
The reports of nontuberculous mycobacteria (NTM) associated with extrapulmonary diseases are increasing in tertiary care hospitals. Despite a significant increase in knowledge about NTM infections, they still represent a diagnostic and therapeutic challenge. The aim of this study is to know the prevalence of NTN among extrapulmonary tuberculosis cases in tertiary care centers in Northern India. A total of 227 culture positive isolates from 756 cases were tested for niacin production and catalase assay. BIO-LINE SD Ag MPT64 TB test and final identification and differentiation between MTBC and different species of NTM were further confirmed by GenoType Mycobacterium CM/AS assay. 71 cases (9.3%) were positive for AFB by ZN staining and 227 cases (30.1%) were positive for mycobacteria by culture. Niacin production and catalase activity were negative in 62/227 (27.4%) strains and after using a panel of different biochemicals and final confirmation by GenoType Mycobacterium CM assay. Out of 227 cultures tested, 165 (72.6%) strains were confirmed as M. tuberculosis complex, and 62 (27.4%) were confirmed as NTM. The most common NTM species identified were M. fortuitum 17 (27.5%) and M. intracellulare 13 (20.9%). The rapid identification of NTM species may help in targeted therapy and management of the diseases.

Abstract
Mycobacterial skin and soft tissue infection (SSTI) includes nontuberculous mycobacterial (NTM) infections, tuberculosis (TB), and leprosy. Diagnosis of mycobacterial SSTI can be challenging due to diverse clinical presentation, low yield from cultured specimens, and nonspecific histopathology on tissue biopsy. In addition, immunosuppressed patients may present with atypical or disseminated disease. Despite aggressive medical treatment and often with surgical intervention, results may be suboptimal with poor outcomes. Regimens typically require multiple antibiotics for extended periods of time and are often complicated by medication side effects and drug-drug interactions. Biopsy with culture is the gold standard for diagnosis, but newer molecular diagnostics and proteomics such as matrix-assisted laser desorption ionization-time of flight mass spectrometry have improved diagnosis with increased identification of clinically significant mycobacteria species in clinically relevant time frames. We will review updates in diagnostic tests along with clinical presentation and treatment of mycobacterial SSTI for NTM, TB, and leprosy.

Abstract
Between October 2012 and August 2014, several Swiss patients developed severe soft tissue infections due to rapidly growing mycobacteria following cosmetic surgery in the Dominican Republic, Ecuador and Mexico. Infections were caused by Mycobacterium abscessus (n=5), Mycobacterium sp. JAN1 (n=1) and M. conceptionense (n=1). Similar cases may have remained unrecognised due to a lack of notification requirements. Microbiological work-up of medical tourists with infections following cosmetic surgery should include rapidly growing mycobacteria.

Abstract
Granuloma annulare is a fairly common entity yet lacks reliable treatment options especially when multiple lesions or dissemination exists. A recent case series suggests that a regimen of three oral antibiotics may prove to be an effective treatment. Our objective is to evaluate the efficacy of once monthly triple antibiotic therapy for granuloma annulare. We conducted an open-label prospective study of subjects with at least five lesions of granuloma annulare who received once monthly rifampin, ofloxacin, and minocycline for 6 months. Improvement was measured with a novel objective Granuloma Annulare Severity Index (GASI) scoring system. Twenty-one subjects enrolled. Ten subjects (48%) achieved at least a 50% reduction in their GASI, including three subjects (14%) who reached 75% improvement and one subject (5%) whose skin cleared. Six subjects (29%) had no change or worsening of their granuloma annulare. Median GASI scores decreased significantly by 15 points (p < 0.01), although the clinical significance of this result is unclear. As this was a small open-label study without a control group, we cannot determine if the results simply reflect the natural course of the disease. The GASI is not a validated assessment tool. Once monthly triple antibiotic use may improve but not clear granuloma annulare over 6 months. Randomized trials may be warranted to further assess this therapy.

Abstract
BACKGROUND Pedicure-associated nontuberculous mycobacterial furunculosis has been reported in the setting of either outbreaks or sporadic case reports. The epidemiology of these infections is not well understood. METHODS Systematic surveillance for pedicure-associated nontuberculous mycobacterial furunculosis was conducted in 2 North Carolina counties from 1 January 2005 through 31 December 2008. A subset of implicated nail salons and control salons was inspected and sampled for nontuberculous mycobacteria. RESULTS Forty cases of suspected or confirmed pedicure-associated nontuberculous mycobacterial furunculosis were reported during the 4-year study period. Furunculosis incidence in the surveillance region was 1.00, 0.96, 0.83, and 0.89 cases per 100,000 population in 2005, 2006, 2007, and 2008, respectively. The responsible organisms primarily belonged to the Mycobacterium chelonae/abscessus group (30 [91%] of 33 isolates). Thirteen implicated salons and 11 control salons were visited and environmentally sampled. An assortment of nontuberculous mycobacteria was cultured from footbaths, but there was no association between the species distribution of the environmental isolates and implication of the salon in human infection. Evidence of suboptimal cleaning (visible debris or surface biofilms) was observed in at least 1 footbath for 11 of 13 implicated salons and 4 of 11 control salons (P = .032). CONCLUSIONS Pedicure-associated mycobacterial furunculosis was endemic in these 2 North Carolina counties during 2005-2008. Suboptimal footbath cleaning may have contributed to these infections, which suggests straightforward means of potential prevention. The relative rarity of this type of infection in the setting of nearly ubiquitous exposure to these pathogens suggests that as yet undefined host-specific or procedure-related factors may be involved in susceptibility to these infections.

Abstract
Mycobacteria exhibit various relationships with amoebae, ranging from the killing of one partner by the other one, to amoebae hosting mycobacteria in trophozoites and cysts. This observation indicates that poorly described biological factors affect the relationships, including mycobacterial cell-wall glycolipids and the size of the mycobacteria. Experimental observations indicate that a majority of environmental, opportunistic mycobacteria but also obligate pathogens including Mycobacterium tuberculosis, Mycobacterium leprae and Mycobacterium ulcerans are inter-amoebal organisms. Amoebae may give opportunities for genetic exchanges between mycobacteria, sympatric intra-amoebal organisms and the amoebae themselves. Amoebae clearly protect opportunistic mycobacterial pathogens during their environmental life but their role for obligate mycobacterial infection remains to be established. Accordingly, water was the source for emerging, community-acquired and health care-associated infection with amoeba-resisting mycobacteria of the Mycobacterium avium, Mycobacterium abscessus and Mycobacterium fortuitum groups, among others. Amoebae are organisms where mycobacteria can be found and, accordingly, amoeba co-culture can be used for the isolation of mycobacteria from environmental and clinical specimens. Looking in amoebae may help recovering new species of mycobacteria.

Lux L, Marshall J, Parker S, Collard S, Rogers B, Fuson S. Do educational interventions targeted to nail salon workers and customers improve infection control practices in these salons?

Abstract
BACKGROUND The Tacoma-Pierce County Department of Health, the Pierce County Antibiotic Resistance Task Force, and the Washington State Department of Licensing (DOL) designed an intervention to determine whether nail salon infection control practices could be improved by educating salon employees and their customers about good infection control practices. METHODS Twenty intervention salons and 26 control salons completed the 3-month study. The intervention group received a letter asking them to "join our campaign to promote healthy people in healthy communities … ." Two DOL pamphlets on cleaning and disinfecting and a tent card with important infection control reminders-targeted to clients on one side and to salon workers on the other side-were also included. Outreach workers from the health department visited 25 (of the original 27) intervention salons once and talked about the materials included in the mailing. Inspection infractions were used to measure compliance with infection control practices. Each salon was inspected by the DOL at baseline, within 1 month after the educational mailing, and within 1 month after an outreach visit from the local health department. RESULTS Both groups exhibited statistically significant decreases in infractions; however, the intervention group exhibited a higher and more significant decrease in infractions than the control group. CONCLUSIONS The intervention and control groups underwent three DOL inspections, which may have resulted in a Hawthorne Effect, with both groups seeing a statistically significant decline in infractions after inspection visits. The more significant decrease in the number of infractions cited in the intervention salons may be due to the educational materials and the health education site visit they received.

Heterogeneity of clinical and environmental isolates of Mycobacterium fortuitum using repetitive element sequence-based PCR: municipal water an unlikely source of community-acquired infections. Epidemiol Infect 2014; 142:2057-64.

Abstract
M. fortuitum is a rapidly growing mycobacterium associated with community-acquired and nosocomial wound, soft tissue, and pulmonary infections. It has been postulated that water has been the source of infection especially in the hospital setting. The aim of this study was to determine if municipal water may be the source of community-acquired or nosocomial infections in the Brisbane area. Between 2007 and 2009, 20 strains of M. fortuitum were recovered from municipal water and 53 patients' isolates were submitted to the reference laboratory. A wide variation in strain types was identified using repetitive element sequence-based PCR, with 13 clusters of ⩾2 indistinguishable isolates, and 28 patterns consisting of individual isolates. The clusters could be grouped into seven similar groups (>95% similarity). Municipal water and clinical isolates collected during the same time period and from the same geographical area consisted of different strain types, making municipal water an unlikely source of sporadic human infection.
