The Profile of Microbiological Pathogens in Diabetic Foot Ulcers

Diabetic foot, a main complication of diabetes mellitus, renders the foot susceptible to infection, and may eventually lead to non-traumatic limb amputation due to the deterioration of diabetic foot ulcers (DFUs). Characterizing the pathogen spectrum and antibiotic susceptibility is critical for the effective treatment of DFUs. In the current study, the characteristics and antibiotic susceptibility of the pathogen spectrum were analyzed. Secretions from the DFUs of 102 patients were cultured, and dominant pathogens were identified by using test cards. Antibiotic susceptibility of dominant pathogens was assayed by the Kirby–Bauer assay. We found that the dominant pathogens varied with age, duration of diabetes, blood sugar control, and the initial cause of ulcers. Moreover, the dominant pathogens were susceptible to at least one antibiotic. However, the antibacterial efficacy of several commonly used antibiotics decreased from 2016 to 2019. Our study indicates that the identification of dominant pathogens and antibiotic susceptibility testing is essential for the treatment of DFUs with effective antibiotics, while the abuse of antibiotics should be strictly restrained to reduce the generation of antibiotic-resistant strains.

Complications of Paget bone disease: a study of 69 patients

Introduction: Paget bone disease (PBD) is characterized by a disorder in the bone remodeling activity at sites of involvement. This can produce dramatic alterations of local bone architecture and causes most of the complications. We aimed to focus on the characteristics of complications of PDB among hospitalized patients. Material and Methods: A retrospective study was conducted, on PBD patients hospitalized in two rheumatology centers from 1994 to 2019. Characteristics of the PBD complications were studied. Results: Sixty-nine patients were collected with a sex ratio of 0.76 and a mean age of 75.4±6.4 years [43-101]. The diagnosis of PBD was established in the average age of 64.2±11.5 years. The primary reason for consultation was pain (78.3%). The PBD was localized in the pelvis (58%), lower limb (42%), spine (36.2%), skull (23.2%) and upper limb (5.8%). It was polyostotic in 44.9% of cases. Dosage of ALP was 324 [68-8390]. The PDB complication rate was 52.2% and it decreased over time. The main complication was osteoarthritis (23.2%), followed by deafness (17.4%), fracture (15.9%), hydrocephalus (7.2%), neurological disease (7.2%) and osteosarcoma (1.4%). The presence of complications was significantly associated with the polyostotic form (p=0.01), the skull localization (p=0.04), an increased ALP (p=0.02). Conclusion: According to our study, the incidence rate of PBD among hospitalized cases is higher among elderly women and decreases over time. Complications related to PDB are frequent (52%). It concerns patients with a polyostotic form, skull localization and high ALP.

STRATEGIES FOR THE PREVENTION OF FACIAL PRESSURE INJURIES CAUSED BY THE USE OF THE PRONE POSITION

Objective: Identify the main strategies for preventing facial pressure injuries caused by the use of the prone position. Methods: Integrative literature review, carried out during the month of March 2021. Articles were searched in the MEDLINE, LILACS, BDENF and IBECS databases. The selected articles were written in English, Portuguese and Spanish, between 2016 and 2021. Duplicates and those that did not include the topic addressed were excluded. Initially, 29 articles were identified. After applying the inclusion and exclusion criteria, 10 articles resulted for analysis. Results: Of the complications related to the use of the prone position, 10 (100%) of the studies address the pressure injury as the main complication of this therapeutic maneuver. As for prevention strategies, the studies analyzed cite the change in position associated with the use of pads and hydrocolloids as the main preventive methods. Conclusion: The following strategies to prevent facial pressure injury by using the prone position were identified: change of decubitus at pre-established times; use of devices that provide relief from pressure points, such as pads and hydrocolloids; and the use of low-cost and easily accessible materials, such as adapted surgical sponges, respecting the anatomical structures of each patient.

Determination of the Median Effective Dose of Dexmedetomidine for the Prevention of Emergence Agitation in Geriatric Patients Undergoing Major Open Surgery With General Anesthesia: A Prospective, Double-Blinded, Dose-Response Trial

Dexmedetomidine can effectively decrease the incidences of emergence agitation (EA) in adult patients, but there are major side effects related to increased dose of dexmedetomidine. The purpose of this study was to determine the median effective dose of dexmedetomidine in the prevention of EA among geriatric patients undergoing major open surgery with general anesthesia. A total of 50 geriatric patients were enrolled in this study. Dexmedetomidine 0.5 μg·kg−1·h−1 continuous intravenous infusion was administered to the first patient. The next dose was increased or decreased by .05 depending on the response of the previous patient, according to the Dixon up-and-down method. An “effective” or “ineffective” response was determined based on the Riker sedation-agitation score (RSAS), we defined “effective” as RSAS<5, and “ineffective” as RSAS≥5. The ED50 of dexmedetomidine in prevention of EA was .30 μg·kg−1·h−1 (95% CI, .27–.33) and the predicted ED95 was .42 μg·kg−1·h−1 (95% CI, .38–.51). The incidence of bradycardia was significantly increased in the group without EA compared to the group with EA (57.1% vs 13.6%, P = .002). The ED50 of dexmedetomidine in prevention of EA was .30 μg·kg−1·h−1 (95% CI, .27–.33) and the predicted ED95 was .42 μg·kg−1·h−1 (95% CI, .38–.51). Bradycardia was the main complication.

EFFICIENCY OF THE NICKEL-TITANIUM ALLOY IN COMPRESSION-INTESTINAL ANASTOMOSIS

На сегодняшний день, несмотря на то, что лечение заболеваний желудочно-кишечного тракта развивается уже много лет, создание желудочно-кишечных анастомозов по-прежнему остается одной из самых сложных и длительных проблем со своими осложнениями. Очевидно, осложнения часто возникают из-за наложения швов. Основное осложнение - повреждение стенки кишечника при наложении швов. Поэтому использование специальных никель-титановых сплавов вместо швов, вероятно, станет основным решением этой острой проблемы. В связи с этим, цель нашего исследования является определение эффективности никель-титановых слитков при компрессионно кишечном анастомозе. Nowadays, despite the fact that the treatment of diseases of the gastrointestinal tract has been developing for many years, the creation of gastrointestinal anastomoses is still one of the most difficult and long-lasting problems with its complications. Obviously, complications often arise from sutures. The main complication is damage to the intestinal wall during suturing. Therefore, the use of special nickel-titanium alloys instead of welds is likely to be the main solution to this acute problem. In this regard, the purpose of our study is to determine the effectiveness of nickel-titanium ingots in compression intestinal anastomosis.

Peritoneal dialysis associated-peritonitis: a preventable complication

Peritoneal dialysis is useful renal replacement therapy for patients with end-stage chronic kidney disease. Latin America has 30% of the world population in peritoneal dialysis and within these countries Mexico covers 73% of them. In our country, the Mexican institute of social security (IMSS by its Spanish acronym) serves more than half of the Mexican population that requires renal replacement therapy. In 2014 it represented 15% of total annual cost of the institution. Peritonitis in peritoneal dialysis is the main complication seen in this renal replacement therapy with morbidity and mortality from 2 to 6%. The epidemiology of peritonitis associated with peritoneal dialysis varies according to the continent, country and dialysis center. The rate of peritonitis per year of each center reflects their quality of care. The prevention, diagnosis and treatment of peritonitis impact in the quality of life of the patient, the success of renal replacement therapy, public health costs and associated mortality. This review addresses the epidemiology, diagnosis, treatment, and preventive measures of peritonitis, focused on the procedures for improving the standards of care.

Effect of Exposure Rates with Customized versus Conventional Titanium Mesh on Guided Bone Regeneration: A Systematic Review and Meta-Analysis

Titanium mesh exposure is the main complication of bone regeneration. In this study, a meta-analysis and performed to clarify the effect of customized titanium mesh versus conventional titanium mesh complications and the time of mesh exposure on edentulous alveolar ridge GBR. Databases, including PubMed, EMBASE, Web of Science and Cochrane Central Register Controlled Trials, were searched by two independent reviewers to retrieve articles published from January 2010 to March 2020, regarding the incidence of complications after GBR surgery, with language limited to English articles. A total of 705 articles were found, and 9 articles were quantitatively analyzed. A funnel plot was made for 10 comprehensive datasets. The combined value of the total exposure rate of titanium mesh was 0.44 (44%, 95% CI=0.30~0.58). The results of subgroup analysis showed that the combined value of the customized titanium mesh exposure rate was 0.31 (31%, 95% CI=0.15~0.51), and the combined value of the conventional titanium mesh exposure rate was 0.51 (51%, 95% CI=0.33~0.69). Based on the findings of the present study, the exposure rate of customized titanium mesh is lower than that of conventional titanium mesh. The design of 3D printing customized titanium mesh avoids nerves and blood vessels, which is of great significance to improve the accurate reconstruction of GBR and provides enough space for implantation and reducing the exposure rate. Soft tissue management (i.e., technical sensitivity) is also an important factor to avoid soft tissue fractures.

Clinical Characteristics of Measles in Infancy: A Hospital Based Study

Background: There is a global resurgence of measles among children in recent years and a number of infants are being affected. Objectives: The aim of the study was to determine the frequency of measles in infancy and to describe their clinical characteristics in a tertiary care children hospital. Methods: A prospective observational study was conducted in Dr. MR Khan Shishu Hospital and Institute of Child Health from March, 2019 to February, 2020. The children who came with signs and symptoms of measles, like fever with maculopapular rash associated with cough, runny nose and conjunctivitis were recorded and frequency of measles in infants among hospitalized measles patients was noted. Infants with measles were enrolled for the study and their clinical characteristics, complications and outcome were determined. Data were analyzed by SPSS version 23. Results: A total of 64 infants were studied. The frequency of measles in infants among hospitalized measles patients was 43%. Forty seven percent infants were between 9 to 10 months. Clinical features were typical and all had fever and maculopapular rash. Pneumonia was the main complication and occurred in 50(78%) cases which was followed by oral ulcer 42(66%), diarrhea 26(41%), febrile seizure 9(14%) and croup 5(8%). Thirty four (53%) infant had normal nutritional status. Only 19.51% infant received first dose of measles vaccine. The mortality rate was 2(3%). Conclusion: A number of children are being affected by measles before completing first year of life and they develop complications which are related to morbidity and mortality. So, control and prevention of measles in infancy should give more importance. DS (Child) H J 2020; 36(1) : 20-24

Dermo-Hipodermites Bacterianas Agudas Não Necrotizantes: Erisipela e Celulite Infeciosa

Non-necrotizing acute dermo-hypodermal infections are infectious processes that include erysipela and infectious cellulitis, and are mainly caused by group A β-haemolytic streptococcus. The lower limbs are affected in more than 80% of cases and the risk factors are disruption of cutaneous barrier, lymphoedema and obesity. Diagnosis is clinical and in a typical setting we observe an acute inflammatory plaque with fever, lymphangitis, adenopathy and leucocytosis. Bacteriology is usually not helpful because of low sensitivity or delayed positivity. In case of atypical presentations, erysipela must be distinguished from necrotizing fasciitis and acute vein thrombosis. Flucloxacillin and cefradine remain the first line of treatment. Recurrence is the main complication, so correct treatment of the risk factors is crucial.
