The bacterial profile and antibiotic susceptibility in skin and soft tissue infections at a tertiary care hospital of Quetta, Pakistan.

Objectives: To determine the bacterial profile and antibiotic susceptibility in skin and soft tissue infections among patients in a tertiary care setting. METHODS: The cross-sectional cohort study was conducted at the Centre for Advanced Studies in Vaccinology and Biotechnology, University of Balochistan, Quetta, Pakistan, from June 2021 to May 2022, and comprised bacteriainfected skin samples that were collected from the Bolan Medical Complex Hospital, Quetta, and the Sandeman Provincial Hospital, Quetta. The swab samples were immediately cultured, and positive samples were evaluated for biochemical tests, antibiotic susceptibility test and polymerase chain reaction. Data was analysed using SPSS 22. RESULTS: Of the 800 samples, 598(74.7%) tested positive for pathogenic bacteria. Staphylococcus aureus accounted for 316(39.5%) infections, followed by clostridium perfringens 18.96(2.37%), escherichia coli 120(15.12%), pseudomonas aeruginosa 98(12.25%) and klebsiella pneumoniae 44(5.5%). Among all the infected samples, 380(47.5%) belonged to males, 218(27.25%) to patients aged 5-20 years, 448(56%) to the uneducated subjects, and 462(57.87%) to patients having lower socioeconomic status. Pseudomonas aeruginosa showed the highest level of resistance against all antibiotics. Conclusion: Regular surveillance and proper use of antibiotics should be encouraged in hospitals to limit the spread of antibiotic resistance against pathogenic bacteria.

Three Cases of Non-Tuberculosis Mycobacterium Skin Infection Outbreak in Beauty Institutions.

BACKGROUND: From June 2021 to July 2021, our hospital confirmed 3 cases of Mycobacterium infection in skin abscesses. All 3 patients underwent thread embedding and weight loss surgery at the same informal beauty institution, with a history of silk protein injection. None of the patients had any other underlying diseases or surgical history. Symptoms and signs show that the disease is acute and the course of the disease is short. All patients have found subcutaneous masses in different parts of the body. In most cases, the masses show redness and swelling, and some of the masses are accompanied by tenderness, wave sensation, and rupture. After some of the masses rupture, purulent secretions can be seen. METHODS: The pus secreted by the skin lesions of the three patients were cultured to a single bacterium, which was identified by MALDI-TOF MS. Multiple locus sequence typing (MLST) was performed using three specific genes (hsp65, rpoB, and secA1) and seven housekeeping genes (argH, cya, glpK, gnd, murC, pta, and purH). The results were queried through the MLST database of Mycobacterium abscess. RESULTS: All three strains of bacteria were Mycobacterium abscess type ST279 massiliense subtype. Three antibacterial drugs including cefmetazole, amikacin, and clarithromycin were administered in combination with 5-aminolevulinic acid photodynamic therapy (ALA-PDT). After 3 - 6 months, there was no obvious redness or swelling in the surrounding tissues of the wound, and no obvious purulent secretions were observed. All patients were cured and discharged from the hospital. After a follow-up of six months, there was no recurrence of the lesions. CONCLUSIONS: Medical institutions must strictly follow infection control guidelines and take preventive measures to prevent such incidents from happening again. ALA-PDT as a combination therapy for nontuberculous Mycobacterium (NTM) skin infections can improve treatment efficacy and shorten antibiotic usage time.

Skin and Soft Tissue Actinomycosis in Children and Adolescents.

BACKGROUND: Pediatric actinomycosis studies are limited to case reports or small case series. In this retrospective cohort study, we aimed to describe characteristics of skin and soft tissue actinomycosis in adolescents and children. METHODS: We conducted the study from January 2019 to December 2022, including patients ≤21 years of age with at least 1-year follow-up data. All clinical cultures obtained under sterile conditions with Actinomyces growth were included. RESULTS: One hundred four patients met inclusion criteria; median age 19 (interquartile range: 17-20) years, 68.3% female, 46.2% Black and 47.1% Hispanic. The median antibiotic treatment duration was 10 (7-10) days, and majority of patients received treatment with non-first-line Actinomyces antibiotics. Infectious disease consultation was requested for only 7 patients during their initial skin and soft tissue actinomycosis treatment. One-third of the patients with skin and soft tissue actinomycosis had documented recurrence within a median of 10 (interquartile range: 6-16) months of the initial episode. Monobacterial culture growth (85.7% vs. 63.8%, P = 0.02), patients with body mass index >25 (75% vs. 52.6%, P = 0.04) and patients with prior abscess in the same area (18.8% vs. 51.4%, P = 0.001) were significantly higher in patients with recurrent actinomycosis compared to the nonrecurrent group. In a univariate logistic regression model, they were found to be significantly associated with recurrence; monobacterial growth [odds ratio (OR): 3.4; 95% confidence interval (CI): 1.2-9.9], body mass index >25 (OR: 2.7; 95% CI, 1.1-7.0) and prior abscess (OR: 4.6; 95% CI: 1.9-11.2). CONCLUSIONS: Our study results highlight the importance of considering Actinomyces species in skin and soft tissue infections, especially in recurrent ones, and risk factors for recurrence. Suboptimal antibiotic utilization, very low numbers of consultations with infectious diseases and high recurrence rate suggest that providers should be informed and updated regarding this rare but hard-to-treat infection.

Secondary Bacterial Infections in Patients with Atopic Dermatitis or Other Common Dermatoses.

Secondary bacterial infections of common dermatoses such as atopic dermatitis, ectoparasitosis, and varicella zoster virus infections are frequent, with Staphylococcus aureus and Streptococcus pyogenes being the bacteria most involved. There are also Gram-negative infections secondary to common dermatoses such as foot dyshidrotic eczema and tinea pedis. Factors favoring secondary bacterial infections in atopic dermatitis, ectoparasitosis, and varicella zoster virus infections mainly include an epidermal barrier alteration as well as itch. Mite-bacteria interaction is also involved in scabies and some environmental factors can promote Gram-negative bacterial infections of the feet. Furthermore, the bacterial ecology of these superinfections may depend on the geographical origin of the patients, especially in ectoparasitosis. Bacterial superinfections can also have different clinical aspects depending on the underlying dermatoses. Subsequently, the choice of class, course, and duration of antibiotic treatment depends on the severity of the infection and the suspected bacteria, primarily targeting S. aureus. Prevention of these secondary bacterial infections depends first and foremost on the management of the underlying skin disorder. At the same time, educating the patient on maintaining good skin hygiene and reporting changes in the primary lesions is crucial. In the case of recurrent secondary infections, decolonization of S. aureus is deemed necessary, particularly in atopic dermatitis.

Impact of traditional cutaneous scarification on anthrax lesions: A series of cases from Cubal, Angola.

OBJECTIVES: Bacillus anthracis infection is a worldwide zoonosis that affects the most vulnerable population and has a high mortality rate without treatment, especially in non-cutaneous presentations. Cutaneous scarification is still common in some regions of the world for the treatment of certain diseases as part of traditional medicine. We describe a series of cutaneus anthrax from a rural setting in Angola where cutaneus scarification is common. CASE PRESENTATION: This is a retrospective observational study describing a series of cutaneous anthrax cases from Cubal (Angola), many of whom were treated with skin scarification before admission. A total of 26 cases were diagnosed from January 2010 to December 2018. None of the cases were confirmed and eight (30.8%) were probable cases according to the Centers for the Disease Control and Prevention anthrax case definition. The median age was 11 (4.7-30.5) years, 17 (65.4%) had lesions on the head, face, or neck and 15 (57.7%) were treated with cutaneous scarification. Nine (34.6%) patients died. Traditional cutaneous scarification was significantly associated with cutaneous superinfection, respiratory, systemic involvement, and death. CONCLUSION: Our case series points to increased complications and worse outcome of cutaneous anthrax disease if treated with skin scarification.

Bacterial Skin and Soft Tissue Infections in Older Adults.

This article focuses on bacterial infections that commonly affect geriatric patients. The elderly population is at a higher risk of contracting bacterial infections due to weakened immune systems and comorbidities. The article explores the cause, pathogenesis, clinical manifestations, and treatment options of these infections. Additionally, antibiotic resistance is a growing concern in the treatment of bacterial infections. The article highlights the importance of preventing these infections through proper hygiene and wound care. This article aims to provide an understanding of bacterial infections in geriatric patients and inform health-care providers on the most effective ways to manage and prevent these infections.

[Bacterial infections of the skin in the context of climate change and migration]. / Bakterielle Infektionen der Haut im Kontext von Klimawandel und Migration.

BACKGROUND: In the context of climate change and migration, both common and previously less common pathogens are gaining importance as cutaneous bacterial infections. OBJECTIVE: To inform medical professionals about challenges to dermatology posed by climate change and migration. MATERIALS AND METHODS: Review of the current literature on emerging antimicrobial resistance and emerging pathogens in general and on the epidemiological situation in Germany in particular. RESULTS: Climate change has a direct impact on microbiological ecosystems in Germany's warming coastal waters leading to an increase of marine V. vulnificus counts and human infections. Secondary to global warming, transmitting vectors of, for example, Lyme disease, rickettsioses and tularemia are also increasing. In addition, infectious diseases like cutaneous diphtheria and mycobacteriosis have been diagnosed in migrants, mostly likely acquired before migration or on the migration route and first diagnosed in Germany. In this context, antimicrobial resistance (e.g. methicillin-resistant Staphylococcus aureus [MRSA] and multidrug-resistant gram-negative bacteria) is gaining importance. CONCLUSION: Due to progressive changes in global climate and ongoing migration, the aforementioned pathogens of infectious skin diseases and changes in antimicrobial resistance patterns have to be expected. Physicians should be aware of these developments in order to offer appropriate diagnostics and treatment. Epidemiological and biogeographic monitoring will be indispensable for managing emerging changes.

Investigation on an outbreak of cutaneous anthrax in a county of Shandong Province, China, 2021.

BACKGROUND: In order to verify the existence of an anthrax outbreak, determine its scope, grasp the epidemiological characteristics and find out the cause of the outbreak and recommend preventive and control measures. METHODS: Etiological hypothesis was developed through descriptive epidemiological methods. Hypotheses were tested by analyzing epidemiological methods by comparing the differences in the incidence of different exposure types. Nucleic acid detection and bacterial isolation and culture in the BSL-2 laboratories. SPSS 21 was used to conduct statistical analysis. RESULTS: A total of 126 family, workshop, shop environment samples and meat samples were collected, and 6 samples were collected from skin lesions of suspected cutaneous anthrax cases. 41 samples were positive by rPCR and 8 strains of Bacillus anthracis were cultivated. Participated in slaughtering, cutting beef of sick cattles was significantly associated with cutaneous anthrax (RR 3.75, 95% CI 1.08-13.07), this behavior is extremely dangerous. CONCLUSIONS: Comprehensive analysis of laboratory results and epidemiological survey results and environmental assessments, we judge this epidemic to be an outbreak of cutaneous anthrax, associated with slaughtering and other processes from infected cattle imported from other province.

Skin infections in Europe: a retrospective study of incidence, patient characteristics and practice patterns.

OBJECTIVE: Acute bacterial skin and skin structure infections (ABSSSIs) are associated with considerable morbidity and a heavy healthcare burden. The primary objectives of this two-phase study were to determine the incidence of skin infections and ABSSSIs in hospitalized patients (Phase A), and to describe the characteristics and treatment of hospitalized patients with ABSSSIs (Phase B). METHODS: This non-interventional, retrospective study was based on data collected from adult patients hospitalized for skin infections in six European countries (Czech Republic, Greece, Italy, Portugal, Russia and Spain) between January 2014 and June 2016. RESULTS: In Phase A, the total hospital incidence of skin infections and ABSSSIs was 2.4 and 1.8 per 1000 patient-days, respectively. Overall, 73.6% of 50,469 hospitalizations for skin infections were for ABSSSIs. Among the 750 patients with ABSSSIs included in Phase B, Gram-positive bacteria were isolated in 24.9%, most commonly methicillin-susceptible Staphylococcus aureus (11.5%). Empirical therapy was administered to 98.1% of patients, most often with a penicillin, with or without a ß-lactamase inhibitor (42.1%). Complete cure was achieved in 46.5% and 34.5% of patients after initial treatment and treatment modification, respectively. Overall, 22.7% of patients had at least one additional ABSSSI-related hospitalization, 47.1% of patients visited the emergency room, 19.3% of patients visited primary care clinics, and 34.8% of patients visited a specialist. CONCLUSION: Treatment of ABSSSIs in Europe is associated with a heavy healthcare burden, highlighting the need for optimized management strategies that may reduce healthcare utilization.

[Epidemiological investigation on an imported cutaneous anthrax case in Shanghai].

Objective: To discuss the challenges and problems of the prevention and control of emerging infectious diseases in Shanghai as a megacities. Methods: An imported case of cutaneous anthrax occurred in Shanghai on May 30, 2019. Shanghai Municipal Center for Disease Control & Prevention conducted an epidemiological investigation and treatment of the cases; after this case, the data of patients with cutaneous anthrax were collected, and an epidemiological study was conducted. Meanwhile, the wound and blood samples of the patient were collected for laboratory testing. Results: Of the seven wound samples of the patient, 6 were positive for the Bacillus anthracis nucleic acid test, and the double serological test results showed a 4-fold increase in the titer of anthrax antibodies. Shanghai CDC conducted an epidemiological investigation of the confirmed cases and observed its contacts. After treatment, the patients recovered, and no other issues appeared among the 19 contacts. Conclusions: Shanghai must strengthen the training of clinicians on emerging infectious diseases to achieve early detection, diagnosis, and treatment of imported infectious diseases and reduce the incidence, spread, and death of the diseases. At the same time, multi-department joint prevention and control are needed to prevent and control secondary cases.

Mycobacterium porcinum Skin and Soft Tissue Infections After Vaccinations - Indiana, Kentucky, and Ohio, September 2018-February 2019.

During December 2018-February 2019, a multistate investigation identified 101 patients with vaccination-associated adverse events among an estimated 940 persons in Kentucky, Indiana, and Ohio who had received influenza; hepatitis A; pneumococcal; or tetanus toxoid, reduced diphtheria toxoid, and acellular pertussis (Tdap) vaccines at the workplace during September 11-November 28, 2018. These vaccines had been administered by staff members of a third-party health care company contracted by 24 businesses. Company A provided multiple vaccine types during workplace vaccination events across 54 locations in these adjoining states. Injection-site wound isolates from patients yielded Mycobacterium porcinum, a nontuberculous mycobacteria (NTM) species in the Mycobacterium fortuitum group; subtyping using pulsed-field gel electrophoresis of all 28 available isolates identified two closely related clusters. Site visits to company A and interviews with staff members identified inadequate hand hygiene, improper vaccine storage and handling, lack of appropriate medical record documentation, and lack of reporting to the Vaccine Adverse Event Reporting System (VAERS). Vaccination-associated adverse events can be prevented by training health care workers responsible for handling or administering vaccines in safe vaccine handling, administration, and storage practices, timely reporting of any suspected vaccination-associated adverse events to VAERS, and notifying public health authorities of any adverse event clusters.

Non-tuberculous cutaneous mycobacterioses

Abstract Non-tuberculous mycobacteriosis, previously known as atypical, anonymous, opportunistic, or unclassified mycobacteriosis, refers to pathogenic mycobacterioses other than those caused by Mycobacterium tuberculosis and Mycobacterium leprae. These mycobacteria are known for their environmental distribution, mainly in water and soil. The incidence of non-tuberculous mycobacteriosis has been increasing in all countries and skin infections are being increasingly studied, mainly with the increase in immunosuppressive conditions and the development of new medications that affect immunological function. In the present article, a detailed narrative review of the literature is carried out to study the main non-tuberculous mycobacteriosis that cause diseases of the skin and appendages. The article also aims to present a historical context, followed by epidemiological, microbiological, and clinical characteristics of these diseases. Practical considerations about the diagnosis and treatment of non-tuberculous mycobacteriosis are detailed.

Cutaneous anthrax associated with handling carcasses of animals that died suddenly of unknown cause: Arua District, Uganda, January 2015-August 2017.

BACKGROUND: Anthrax is a zoonotic disease that can be transmitted to humans from infected animals. During May-June 2017, three persons with probable cutaneous anthrax were reported in Arua District, Uganda; one died. All had recently handled carcasses of livestock that died suddenly and a skin lesion from a deceased person tested positive by PCR for Bacillus anthracis. During July, a bull in the same community died suddenly and the blood sample tested positive by PCR for Bacillus anthracis. The aim of this investigation was to establish the scope of the problem, identify exposures associated with illness, and recommend evidence-based control measures. METHODS: A probable case was defined as acute onset of a papulo-vesicular skin lesion subsequently forming an eschar in a resident of Arua District during January 2015-August 2017. A confirmed case was a probable case with a skin sample testing positive by polymerase chain reaction (PCR) for B. anthracis. Cases were identified by medical record review and active community search. In a case-control study, exposures between case-patients and frequency- and village-matched asymptomatic controls were compared. Key animal health staff were interviewed to learn about livestock deaths. RESULTS: There were 68 case-patients (67 probable, 1 confirmed), and 2 deaths identified. Cases occurred throughout the three-year period, peaking during dry seasons. All cases occurred following sudden livestock deaths in the villages. Case-patients came from two neighboring sub-counties: Rigbo (attack rate (AR) = 21.9/10,000 population) and Rhino Camp (AR = 1.9/10,000). Males (AR = 24.9/10,000) were more affected than females (AR = 0.7/10,000). Persons aged 30-39 years (AR = 40.1/10,000 population) were most affected. Among all cases and 136 controls, skinning (ORM-H = 5.0, 95%CI: 2.3-11), butchering (ORM-H = 22, 95%CI: 5.5-89), and carrying the carcass of livestock that died suddenly (ORM-H = 6.9, 95%CI: 3.0-16) were associated with illness. CONCLUSIONS: Exposure to carcasses of animals that died suddenly was a likely risk factor for cutaneous anthrax in Arua District during 2015-2017. The recommendations are investigation of anthrax burden in livestock, prevention of animal infections through vaccinations, safe disposal of the carcasses, public education on risk factors for infection and prompt treatment of illness following exposure to animals that died suddenly.

Non-tuberculous cutaneous mycobacterioses.

Predictors of surgical intervention and visual outcome in bacterial orbital cellulitis.

ABSTRACT: This study aims to identify predictive factors associated with surgical intervention and the visual outcome of orbital cellulitis and to evaluate the treatment outcomes.A retrospective study involving 66 patients (68 eyes; 64 unilateral and 2 bilateral) diagnosed with bacterial orbital cellulitis was conducted between November 2005 and May 2019.The mean (± standard deviation) age was 42.1 (± 25.8) years (range: 15 days-86 years). Sinusitis was the most frequent predisposing factor, occurring in 25 patients (37.9%), followed by skin infection in 10 patients (15.2%), and acute dacryocystitis in 9 patients (13.6%). Subperiosteal abscesses were found in 24 eyes and orbital abscesses in 19 eyes. Surgical drainage was performed in 31 eyes. Regarding the abscess volume for surgical drainage, a cut-off of 1514 mm3 showed 71% sensitivity and 80% specificity. There was significant improvement in visual acuity (VA) and decrease in proptosis after treatment (for both, P ≤ .001). Only pre-treatment VA ≤20/200 was a significant predictor for post-treatment VA of 20/50 or worse (adjusted odds ratio: 12.0, P = .003). The presence of a relative afferent pupillary defect was the main predictor of post-treatment VA of 20/200 or worse (adjusted odds ratio: 19.0, P = .003).The most common predisposing factor for orbital cellulitis in this study was sinusitis. VA and proptosis significantly improved after treatment. We found that the abscess volume was strongly predictive of surgical intervention. Pre-treatment poor VA and the presence of relative afferent pupillary defect can predict the worst visual outcome. Hence, early detection of optic nerve dysfunction and prompt treatment could improve the visual prognosis.

Bacterial Skin Infections in Hospitalized Patients with Bullous Pemphigoid.

OBJECTIVE: To explore the features and risk factors of bacterial skin infections (BSIs) in hospitalized patients with bullous pemphigoid (BP). METHODS: Records were retrospectively reviewed for 110 hospitalized patients with BP admitted to Peking University First Hospital between 2013 and 2019. Bacterial species and drug resistance were assessed, and then the underlying risk factors for BSIs were evaluated. RESULTS: Infections were present in 40% (44/110) of the patients. Staphylococcus aureus (72.7%, 32/44) was the most common bacterium, and it was highly resistant to penicillin (81.3%, 26/32), erythromycin (62.5%, 20/32), and clindamycin (56.3%, 18/32), but 100.0% sensitive to vancomycin and tigecycline. Coronary heart disease (P = .02; odds ratio [OR], 12.68), multisystem comorbidities (P = .02; OR, 3.67), hypoalbuminemia (P = .04; OR, 3.70), high levels of anti-BP180 antibodies (>112.4 U/mL; P = .003; OR, 6.43), and season (spring: reference; summer: P = .002; OR, 23.58; autumn: P = .02; OR, 12.19; winter: P = .02; OR, 13.19) were significantly associated with BSIs. CONCLUSIONS: Hospitalized patients with BP had a high incidence of BSIs, and those patients with underlying risk factors require careful management to prevent and control BSIs.

Prospective Surveillance of Primary Healthcare Presentations for Scabies and Bacterial Skin Infections in Fiji, 2018-2019.

Scabies, impetigo, and other skin and soft tissue infections (SSTIs) are highly prevalent in many tropical, low-middle income settings, but information regarding their burden of disease is scarce. We conducted surveillance of presentations of scabies and SSTIs, including impetigo, abscesses, cellulitis, and severe SSTI, to primary health facilities in Fiji. We established a monthly reporting system over the course of 50 weeks (July 2018-June 2019) for scabies and SSTIs at all 42 public primary health facilities in the Northern Division of Fiji (population, ≈131,914). For each case, information was collected regarding demographics, diagnosis, and treatment. There were 13,736 individual primary healthcare presentations with scabies, SSTI, or both (108.3 presentations per 1000 person-years; 95% confidence interval [CI], 106.6-110 presentations). The incidence was higher for males than for females (incidence rate ratio [IRR], 1.15; 95% CI, 1.11-1.19). Children younger than 5 years had the highest incidence among all age groups (339.1 per 1000 person-years). The incidence was higher among the iTaukei (indigenous) population (159.9 per 1000 person-years) compared with Fijians of Indian descent (30.1 per 1000 person-years; IRR, 5.32; 95% CI, 5.03-5.61). Abscess was the condition with the highest incidence (63.5 per 1,000 person-years), followed by scabies (28.7 per 1,000 person-years) and impetigo (21.6 per 1,000 person-years). Scabies and SSTIs impose a substantial burden in Fiji and represent a high incidence of primary health presentations in this population. The incidence in low-middle income settings is up to 10-times higher than that in high-income settings. New public health strategies and further research are needed to address these conditions.

Investigation of an anthrax outbreak in Makoni District, Zimbabwe.

BACKGROUND: Anthrax continues to be a disease of public health importance in Zimbabwe, with sporadic outbreaks reported annually in many parts of the country. A human anthrax outbreak occurred in wards 22 and 23 of Makoni District from mid-June 2013 to end of January 2014, following cattle deaths in the wards. Laboratory tests confirmed anthrax as the cause for the cattle deaths. This study investigated the clinical characteristics, distribution of cases (places, person and time) and risk factors for contracting the anthrax disease. We also assessed the environment, district preparedness and response, and outbreak prevention and control measures. METHODS: We conducted an outbreak investigation using a mixed-methods design. A 1:1 case-control study was used to assess risk factors for contracting anthrax. The controls were frequency matched to cases by sex. Data were collected using a structured interviewer-administered questionnaire. Environmental assessment, district preparedness and response, and outbreak prevention and control measures were assessed using a checklist, observations, and key informant interviews. Multivariable unconditional logic regression analysis was performed to identify independent risk factors associated with contracting anthrax. RESULTS: We interviewed 37 of the 64 cases, along with 37 controls. All the cases had cutaneous anthrax, with the hand being the most common site of the eschar (43%). Most of the cases (89%) were managed according to the national guidelines. Multivariable analysis demonstrated that meat sourced from other villages [vs butchery, OR = 15.21, 95% CI (2.32-99.81)], skinning [OR = 4.32, 95% CI (1.25-14.94)], and belonging to religions that permit eating meat from cattle killed due to unknown causes or butchered after unobserved death [OR = 6.12, 95% CI (1.28-29.37)] were associated with contracting anthrax. The poor availability of resources in the district caused a delayed response to the outbreak. CONCLUSION: The described anthrax outbreak was caused due to contact with infected cattle meat. Although the outbreak was eventually controlled through cattle vaccination and health education and awareness campaigns, the response of the district office was initially delayed and insufficient. The district should strengthen its emergency preparedness and response capacity, revive zoonotic committees, conduct awareness campaigns and improve surveillance, especially during outbreak seasons.

Incidence of bacterial skin infections in Libya: a retrospective population-based study

Introduction: The global burden of bacterial skin infection is substantial. We aimed to determine the common pathogens causes skin infections and their antimicrobial resistance pattern. Methods: A retrospective record review of data claimed from the microbiology department at Ber-Ustta Milad skin hospital between Jan 2009 to December 2018 was conducted. The consequence of interest was the antimicrobial sensitivity of bacterial isolates. Chi square was used for statistical analysis. Results: Out of 1,141 collected samples, a total of 455 isolates of different medically-significant bacteria were analyzed. The most common pathogen was S. aureus (97.14%), followed by E. coli (93.71%), and the least common was Shigella (0.57%). From the various inoculated samples, S. aureus and Proteus were highly resistant to penicillin (34.3%, 75% respectively) and ampicillin (28.6%, 62.5% respectively). E. coli was highly resistant to ampicillin (45.12%) and penicillin (35.96%), whereas the lowest resistant was against imipenem (3.05%). While, Pseudomonas was highly resistant to ampicillin and augmentin (62.5%), whereas the lowest resistance rate was marked to erythromycin, sulfamethoxazole and imipenem (25%). Ciprofloxacin, gentamicin and nalidixic acid were the only sensitive agents. Conclusions: There is a high burden of bacterial resistance to common antibiotics in our population samples. Recognition of the potential resistant strains of pathogen causing skin infection can help in guiding proper choice of antibiotic therapy (AU)

Sanitation, Obesity, and Low Body Mass Index as Risk Factors for Bacterial Skin Infections.

BACKGROUND: Bacterial skin infections can cause significant disability and can lead to mortality with inadequate treatment. OBJECTIVE: To determine whether sanitation and body mass index (BMI) are statistically significant risk factors for the incidence and prognosis of bacterial skin infections. METHODS: Country-level data regarding the age-standardized rates of incidence, prevalence, and years lived with disability (YLD) from bacterial skin infection per 100 000 persons from the Global Burden of disease dataset, and country-level data on age-standardized prevalence of obesity (BMI ≥30) and low BMI (BMI <18.5) from World Health Organization Global Health Observatory data repository were analyzed. Regression models were created to examine the effects of sanitation, obesity, and low BMI on the burden of bacterial skin infections. RESULTS: The percentage of population using basic sanitation services was positively associated with incidence, prevalence, and YLD from bacterial skin infections (P < .05). After controlling for sanitation, in countries with more than 50% of the population using basic sanitation services, obesity was positively associated with incidence, prevalence, and YLD from bacterial skin infections (P < .05). In countries with less than or equal to 50% of the population using basic sanitation services, low BMI was positively associated with incidence, prevalence, and YLD from bacterial skin infections (P < .05). CONCLUSIONS: Improving sanitation access in all countries, reducing the percentage of obese population in countries with good sanitation/hygiene techniques, and addressing malnutrition in countries with poor sanitation/hygiene techniques may help to reduce the burden of bacterial skin infections.
