RESUMEN

Bacteria living in biofilms exhibit altered growth phenotypes, while the biofilm provides benefits, the foremost of which is a certain protection against both immune system and killing effect by antimicrobials. Laser-activated irrigation (LAI) and passive ultrasonic irrigation (PUI) have been proposed as alternative methods for cleaning and disinfecting the root canal, as an adjuvant to conventional chemo-mechanical preparation in order to improve debridement and disinfection. Nevertheless, the potential antibacterial effect of LAI using 0.5% of sodium hypochlorite (NaOCl) has received little attention. Glass Pasteur pipettes were used to mimic single-tooth root canal and to build Enterococcus faecalis biofilm. Several irrigants and treatments were assayed for 60 s including (I) Saline, (II) NaOCl 0.5%, (III) NaOCl 5%, (IV) Er,Cr:YSGG, (V) Saline + LAI, (VI) NaOCl 0.5% + LAI, (VII) Saline + PUI, and (VIII) NaOCl 0.5% + PUI. Bacterial reduction was measured by counting the colony-forming units (CFUs). Additionally, AFM visualization and measurement of nano-roughness parameters were used to evaluate LAI effect on bacteria. NaOCl 5% unpowered and NaOCl 0.5% + LAI were capable of eliminating all bacteria, whereas non-activated saline solution and NaOCl 0.5% failed to eliminate E. faecalis. Lower efficiencies were achieved by PUI. Surface analysis by AFM revealed apparent alterations in NaOCl + LAI-treated cells. The Er,Cr:YSGG laser-activated irrigation (LAI) increased the bactericidal efficiency of 0.5% NaOCl against E. faecalis biofilm.

RESUMEN

BACKGROUND: The reuse of implant healing abutments is common in dental practice. Effective elimination of bacteria and viruses is accomplished by conventional sterilization. The aim of this work was to explore the eventual survival of microorganisms on sterilized healing abutments and to rule out the presence of transmissible organic material after standard procedures. MATERIAL AND METHODS: A total of 55 healing abutments previously used in patients will be washed and sterilized in a steam autoclave at 121 C for 15 min. Each healing abutment will be cultured in Brain Heart Infusion broth (BHI) under strict aseptic conditions. Besides, two control groups will be included: one of 3 unused healing abutments, and the other of just medium. After 10 days at 37°C under a 5% CO2 100 µl of the broth will be plated on solid media (Brain Infusion Agar, BHIA) and Columbia Blood agar to test for sterility. The remaining volume will be centrifuged, the sediment fixed, and a Gram stain performed to discard the presence of non-cultivable microorganisms. Moreover, to determine the presence of remaining organic material after the cleaning and sterilizing treatments, the bioburden will be determined by measuring total organic carbon (TOC) in another 10 previously used healing abutments, cleaned and sterilized, that will be submerged in Milli-Q water and sonicated. RESULTS: No bacterial growth was detected on any of the 58 cultured abutments, indicating that the sterilization was completely satisfactory in terms of removal of live bacteria or spores. Nevertheless, significant amounts of organic carbon may still be recovered (up to 125,31 µg/abutment) after they have been sterilized. CONCLUSIONS: Significant amounts of the bioburden remained adhered to the surfaces in spite of the cleaning and sterilization procedures. Taking into account our results and data from other authors, the presence of infectious particles on the reused healing abutments such as prions cannot be ruled out.

RESUMEN

OBJECTIVE: Hydrosurgical debridement allows removal of non-viable tissue, preserving healthy tissues. This study was designed to analyse whether hydrosurgery, used in a clinical wounds unit, is an effective and safe method that may reduce debridement time. METHODS: Patients' wounds had the following characteristics: wounds with devitalised tissue needing rapid debridement, wounds with cavities, or non-healing wounds. Hydrosurgical debridement uses a pressurised stream of saline (0.9% sodium chloride) and a vacuum around this stream to remove the devitalised tissue of the wound, preserving healthy surrounding tissues. RESULTS: This prospective study comprised of 53 wounds from 39 patients. The wound aetiology included 39.7% arterial insufficiency, 22.6% pressure ulcers (PUs), 15.1% diabetic foot ulcers (DFUs), 9.4% venous leg ulcers (VLUs), and 13.2% from other aetiologies. The percentage of wounds according the size was the following: 32.1% (<10cm2), 43.4% (10-49cm2), 15.1% (50-99cm2), and 9.4% (≥100cm2). Superficial wounds were 43.4% of the total and 56.6% of wounds had cavities. Pain associated with the hydrosurgery was mild to moderate. There were no hydrosurgery-related adverse events. For effective debridement, the required sessions were as follows: one procedure (73.6%), two procedures (18.9%) and three procedures (7.5%). There was a statistical significant direct correlation (r=0.307) between the number of required sessions and wound size. All patients improved in a week (>80% of granulation tissue). CONCLUSION: We demonstrate that hydrosurgery is an effective and rapid debridement method that can be used safely in the outpatient setting.

RESUMEN

BACKGROUND: Diabetes Mellitus has become a global epidemic and presents many complications, usually proportional to the degree and duration of hyperglycemia. The aim of this systematic review was to investigate the different oral manifestations associated with Diabetes Mellitus. MATERIAL AND METHODS: A MEDLINE search for "Diabetes Mellitus and oral manifestations" was performed. A further search was conducted for "diabetes" and its individual oral manifestation. Inclusion criteria were as follows: human clinical studies with a minimum of 30 patients; studies published in relevant scientific journals between January 1998 and January 2016. Nineteen studies fulfilled the inclusion criteria and were analyzed, assessing the strength of scientific evidence according to recommendations made by the Centre for Evidence-Based Medicine, Oxford (OCEBM), which permits adequate assessment of prevalence studies. RESULTS: A total 3,712 patients (2,084 diabetics) were included in the studies reviewed. Of the 19 studies analyzed, 4 were longitudinal studies and 15 cross-sectional studies. Periodontal disease, periapical lesions, xerostomia and taste disturbance were more prevalent among diabetic patients. An association between diabetes and caries and mucosal lesions proved positive in 5 out of 10 studies. CONCLUSIONS: Despite multiple oral manifestations associated with DM, awareness of the associations between diabetes, oral health, and general health is inadequate. It is necessary for doctors and dentists to be aware of the various oral manifestations of diabetes in order to make an early diagnosis.

RESUMEN

BACKGROUND AND OBJECTIVES: The homologous group of sweet grasses belongs to the Pooideae subfamily, but grass pollen species from other subfamilies can also cause allergy, such as Cynodon dactylon (Chloridoideae) and Phragmites communis (Arundinoideae). C dactylon and P communis have not been included in the sweet grasses homologous group because of their low cross-reactivity with other grasses. The aims of this study were to investigate the profile of sensitization to C dactylon and P communis in patients sensitized to grasses and to analyze cross-reactivity between these 2 species and temperate grasses. METHODS: Patients were skin prick tested with a grass mixture (GM). Specific IgE to GM, C dactylon, P communis, Cyn d 1, and Phl p 1 was measured by ImmunoCAP. A pool of sera was used for the immunoblot assays. Cross-reactivity was studied by ELISA and immunoblot inhibition. RESULTS: Thirty patients had sIgE to GM. Twenty-four (80%) had positive results for C dactylon, 27 (90%) for P communis, 22 (73.3%) for nCyn d 1, and 92.9% for rPhl p 1. Bands were detected in the 3 extracts by immunoblot. Inhibition of GM was not observed with C dactylon or P communis by immunoblot or ELISA inhibition. When C dactylon or P communis were used in the solid phase, GM produced almost complete inhibition. CONCLUSIONS: Eighty percent of patients sensitized to grasses were also sensitized to C dactylon and 90% were sensitized to P communis. Sensitization to these species seems to be induced by allergens different to those in sweet grasses.

RESUMEN

In the last decades, the encapsulation of antibiotics into nanoparticulate carriers has gained increasing attention for the treatment of infectious diseases. Sodium colistimethate-loaded solid lipid nanoparticles (Colist-SLNs) and nanostructured lipid carriers (Colist-NLCs) were designed aiming to treat the pulmonary infection associated to cystic fibrosis patients. The nanoparticles were freeze-dried using trehalose as cryoprotectant. The stability of both nanoparticles was analysed over one year according to the International Conference of Harmonisation (ICH) guidelines by determining the minimum inhibitory concentration (MIC) against clinically isolated Pseudomonas aeruginosa strains and by studying their physico-chemical characteristics. The results showed that Colist-SLNs lost their antimicrobial activity at the third month; on the contrary, the antibacterial activity of Colist-NLCs was maintained throughout the study within an adequate range (MIC ≤16 µg/mL). In addition, Colist-NLCs exhibited suitable physico-chemical properties at 5 °C and 25 °C/60% relative humidity over one year. Altogether, Colist-NLCs proved to have better stability than Colist-SLNs.

RESUMEN

OBJECTIVES: The therapeutic arsenal for MRSA infections is limited. The aim of this study was to assess the non-inferiority of a combination of trimethoprim/sulfamethoxazole plus rifampicin versus linezolid alone for the treatment of MRSA infection. METHODS: We conducted a randomized, open-label, single-centre, non-inferiority trial comparing trimethoprim/sulfamethoxazole (160 mg/800 mg three times daily) plus rifampicin (600 mg once a day) versus linezolid (600 mg twice a day) alone in adult patients with various types of MRSA infection. Patients were allocated 1:1 to either regimen. The primary outcome was clinical cure at 6 weeks after the end of treatment (non-inferiority margin 20%) assessed by both ITT and PP analyses. Secondary outcomes included the microbiologically documented persistence of MRSA in clinical cultures, mortality and adverse events. The study protocol has been registered with ClinicalTrials.gov (NCT00711854). RESULTS: Overall, 150 patients were randomized to one of the two treatment arms between January 2009 and December 2013 and were included in the ITT analysis. Of these 56/75 (74.7%) in the linezolid group and 59/75 (78.7%) in the trimethoprim/sulfamethoxazole and rifampicin group experienced clinical success (risk difference 4%, 95% CI -9.7% to 17.6%). The results were confirmed by the PP analysis, with 54/66 (81.8%) cured patients in the linezolid group versus 52/59 (88.1%) in the trimethoprim/sulfamethoxazole and rifampicin group (risk difference 6.3%, 95% CI -6.8% to 19.2%). There were no statistically significant differences between the two groups in any of the secondary outcomes, including microbiologically documented failure. Four adverse drug reactions attributed to the study medication occurred in the linezolid group versus nine in the trimethoprim/sulfamethoxazole and rifampicin group. CONCLUSIONS: Compared with linezolid, trimethoprim/sulfamethoxazole and rifampicin seems to be non-inferior in the treatment of MRSA infection.

RESUMEN

OBJECTIVES: To evaluate patient outcomes and need for further interventions in women with a morbidly adherent placenta (MAP), before and after introduction of the Triple-P procedure involving placental non-separation, myometrial excision and reconstruction of the uterine wall. METHODS: Between December 2007 and February 2014, 30 patients with MAP were treated at our center. In 2007, we instituted a policy of bilateral prophylactic occlusion balloon catheter placement in both internal iliac arteries followed by Cesarean section with non-placental separation and preservation of the uterus. In 2010, the surgical technique was modified and the Triple-P procedure introduced. As a result, 19 women in our study received the Triple-P protocol (study group) and 11 did not (control group). The quantity of blood replacement products, estimated blood loss, and necessity for uterine arterial embolization and/or hysterectomy were recorded retrospectively and compared between the two groups. RESULTS: Placenta percreta was confirmed in six (54.5%) patients in the control group and 13 (68.4%) in the study group. Estimated mean blood loss during the procedure was lower in the study group than in the control group (1.70 L vs 2.17 L, respectively), but the difference was not statistically significant (P = 0.445). The risks of postpartum hemorrhage (PPH) and hysterectomy were statistically significantly lower in the study group (PPH, 54.5% vs 15.8%; P = 0.035; hysterectomy, 27.3% vs 0.0%; P = 0.045). As a consequence, there was a significant decrease in duration of inpatient stay in the study group (P = 0.044). CONCLUSION: Introduction of the Triple-P procedure conveyed a significantly reduced rate of hysterectomy, PPH and duration of hospital stay in patients with MAP. .

RESUMEN

Microbial biofilms are involved in almost all infectious pathologies of the oral cavity. This has led to the search for novel therapies specifically aimed at biofilm elimination. In this study, we used atomic force microscopy (AFM) to visualize injuries and to determine surface roughness, as well as confocal laser scanning microscopy (CLSM) to enumerate live and dead bacterial cells, to determine the effects of photodynamic therapy (PDT) on Enterococcus faecalis biofilms. The AFM images showed that PDT consisting of methylene blue and a 670-nm diode laser (output power 280 mW during 30 s) or toluidine blue and a 628-nm LED light (output power 1000 mW during 30 s) induced severe damage, including cell lysis, to E. faecalis biofilms, with the former also causing an important increase in surface roughness. These observations were confirmed by the increase in dead cells determined using CLSM. Our results highlight the potential of PDT as a promising method to achieve successful oral disinfection.

RESUMEN

AIM: To report experience of prophylactic occlusion balloon catheters (POBCs) in both internal iliac arteries before caesarean section, with or without embolization, to preserve the uterus and reduce haemorrhage. METHODS AND MATERIALS: Twenty-seven women diagnosed with morbidly adherent placenta (MAP) and with suspected placenta percreta underwent POBC placement before caesarean section. The balloons were inflated immediately after delivery of the baby. The patients' case notes were reviewed retrospectively for histological grading of MAP, blood loss, transfusion, requirement of uterine artery embolization (UAE), or hysterectomy, radiation dose, and infant or maternal morbidity and mortality. RESULTS: MAP was confirmed histologically as percreta in 17, accreta in eight, and increta in two women. Mean blood loss was 1.92 l (range 0.5-12 l). Postpartum haemorrhage (PPH) occurred in nine patients. Eight were referred for UAE, which was successful in six. Immediate peri-partum hysterectomy was performed in one patient. Three women in total required hysterectomy, two after recurrent haemorrhage after UAE. No foetal morbidity or mortality occurred. No maternal mortality occurred. There was one case of iliac artery thrombosis, which resolved with conservative therapy. CONCLUSION: POBC, with or without UAE, contributes to reduction of blood loss and preservation of the uterus in women with MAP.

RESUMEN

Topical application of antihistamines commonly leads to sensitization for patients, but systemic administration of antihistamines rarely induces allergic hypersensitivity, which is mainly linked to phenothiazine-derived and piperazine-derived compounds. We report a 70-year-old woman whose medical history included lichen planus, and who was referred by the dermatology department of our hospital for suspected allergy to corticosteroids. The reason for referral was that on the fourth day of treatment with prednisone and hydroxyzine, the patient presented a bilateral highly pruritic palmar erythema that evolved to a generalized morbilliform rash with subsequent complete desquamation. At a later time, she took cetirizine for a cold, and developed palmar erythema and desquamation. Skin tests (prick and intradermal tests) were performed with steroids, and patch tests (read after 48 and 96 h) with corticosteroids and antihistamines. Controlled oral challenge tests were performed with prednisone and with an alternative antihistamine. Skin tests were negative for all corticosteroids. Patch tests were negative for all corticosteroids, but the antihistamine test was positive for hydroxyzine. Oral challenge with prednisone and dexchlorpheniramine was negative. The patient was diagnosed with cutaneous drug eruption from hydroxyzine and cetirizine. We consider it is important to assess every patient whose skin condition worsens after treatment with antihistamines, especially hydroxyzine, because it is known that antihistamines are often not recognised as the culprit in cases of cutaneous eruption.

RESUMEN

OBJECTIVE: We present two adult and three paediatric patients who had allergic reactions after cheese ingestion and subsequently tolerated cow's milk derivatives. The objective of this study was to determine possible cross-reactivity between different types of cheese. METHODS: Skin tests were performed to cow's milk fractions, and prick-prick tests for goat, sheep and cow cheese. Specific IgE to the fractions of cow's milk and cow, sheep and goat cheese was analysed. The protein profile of cow, sheep and goat cheese extracts was determined by SDS-PAGE and the allergenic profile by immunoblot. Cross-reactivity was investigated by immunoblot inhibition. RESULTS: Skin tests were positive for casein in the patients. The prick-prick tests were positive for the three cheeses in patients 1 and 4, for goat and sheep cheese in patients 2 and 3, and for sheep cheese in patient 5. The specific IgE test was positive in patients 1, 3 and 4 for goat and sheep cheese, and negative in patients 2 and 5. Serum 3 and 4 clearly recognised goat and sheep cheese extracts. Goat casein was almost completely inhibited with sheep casein and partially inhibited with goat and sheep serum proteins, while there was no inhibition with cow cheese. Sheep casein was totally inhibited with sheep serum proteins. Sheep casein was inhibited with goat and cow caseins, suggesting cross-reactivity among the three types of cheese. CONCLUSIONS: We showed sensitisation to goat and sheep cheese in two patients, and only to sheep cheese in another two of the studied patients.

RESUMEN

Facing the severity of the impact of climate change and environmental degradation on human health, 32 Internal Medicine societies, colleges, and associations of 29 Spanish and Portuguese-speaking countries issue a consensus document in which they call for the implication of doctors and all health professionals in the global fight against the causes of these changes. This commitment requires the cooperation of health-related organizations, elaboration and implementation of good environmental sustainability practices, greater awareness of professionals and population, promotion of education and research in this area, increasing climate resilience and environmental sustainability of health systems, combating inequalities and protecting the most vulnerable populations, adopting behaviors that protect the environment, and claiming Internal Medicine as a core specialty for empowerment of the health system to respond to these challenges.

RESUMEN

Atrial fibrillation is the most frequent chronic arrhythmia in patients with chronic kidney disease. Oral anticoagulation with vitamin K antagonists and now direct oral anticoagulants have been and are the fundamental pillars for the prevention of thromboembolic events. However, there are no randomized clinical trials on the risk-benefit profile of oral anticoagulation in patients with chronic kidney disease stage 5 on peritoneal dialysis and there is little evidence in the literature in this population. The objective of our study was to know the prevalence, treatment and professionals involved in the management of atrial fibrillation in peritoneal dialysis patients. For this purpose, we performed a descriptive analysis through a survey sent to different peritoneal dialysis units in Spain. A total of 1,403 patients on peritoneal dialysis were included in the study, of whom 186 (13.2%) had non-valvular atrial fibrillation. In addition, the assessment of the scores of thromboembolic and bleeding risks for the indication of oral anticoagulation was mainly carried out by the cardiologist (60% of the units), as well as its prescription (cardiologist 47% or in consensus with the nephrologist 43%). In summary, patients on peritoneal dialysis have a remarkable prevalence of non-valvular atrial fibrillation. Patients frequently receive oral anticoagulation with vitamin K antagonists, as well as direct oral anticoagulants. The data obtained regarding the scores used for the assessment of thromboembolic and bleeding risk, treatment and involvement by Nephrology indicates that there is a need for training and involvement of the nephrologist in this pathology.

RESUMEN

Age-0+ year juvenile Argentine hake Merluccius hubbsi (60-150 mm total length, L(T)) from San Jorge Gulf, north Patagonian shelf region of the Argentine Sea, had an almost exclusively pelagic diet dominated by the hyperiid amphipod Themisto gaudichaudii and the euphausiid Euphausia lucens. This suggested that final settlement and permanent demersal habitat utilization might not, as previously reported, occur at earlier sizes (c. 20 mm L(T)). Their feeding strategy involves specialization at a population level towards both the main pelagic prey, indicating a narrow trophic niche. Novel data are provided which contribute to the growing body of information in relation to the age-0+ year transitional stage in demersal fishes and particularly to M. hubbsi recruitment in the Argentine Sea.

RESUMEN

AIMS: This work aims to analyze the structure, activity, and outcomes of internal medicine units and departments (IMU) of the Spanish National Health System (SNHS) and to analyze the challenges for the specialty and propose policies for improvement. It also aims to compare the results from the 2021 RECALMIN survey with IMU surveys from previous years (2008, 2015, 2017, 2019). METHODS: This work is a cross-sectional, descriptive study of IMUs in acute care general hospitals of the SNHS that compares data from 2020 with previous studies. The study variables were collected through an ad hoc questionnaire. RESULTS: Between 2014 and 2020, hospital occupancy and discharges by IMU increased (annual mean of 4% and 3.8%, respectively), as did hospital cross-consultation and initial consultation rates (2.1% in both cases). E-consultations increased notably in 2020. Risk-adjusted mortality and length of hospital stay did not show significant changes from 2013-2020. Progress in the implementation of good practices and systematic care for complex chronic patients was limited. A consistent finding in RECALMIN surveys was the variability among IMUs in terms of resources and activity, though no statistically significant differences were found in regard to outcomes. CONCLUSIONS: There is considerable room for improvement in the operation of IMUs. The reduction in unjustified variability in clinical practice and inequities in health outcomes are a challenge for IMU managers and the Spanish Society of Internal Medicine.

RESUMEN

Antibiotic-resistant bacteria are becoming one of the most important problems in health care because of the number of resistant strains and the paucity of new effective antimicrobials. Since antibiotic-resistant bacteria will continue to increase, it is necessary to look for new alternative strategies to fight against them. It is generally accepted that Gram-negative bacteria are intrinsically less susceptible than Gram-positive bacteria to antimicrobials. The main reason is that Gram-negative bacteria are surrounded by a permeability barrier known as the outer membrane (OM). Hydrophilic solutes most often cross the OM through water-filled channels formed by a particular family of proteins known as porins. This work explores the possibility of using exogenous porins to lower the required amounts of antibiotics (ampicillin, ciprofloxacin, cefotaxime, clindamycin, erythromycin, and tetracycline). Porins had a bactericidal effect on Escherichia coli cultures, mainly in the logarithmic phase of growth, when combined with low antibiotic concentrations. The use of different antibiotic-porin mixtures showed a bactericidal effect greater than those of antibiotics and porins when used separately. It was possible to observe different behaviors according to the antibiotic type used.

RESUMEN

Due to the increase of choices relative to antifungals, there is a need to improve the standardization of in vitro methods used to determine the antifungal susceptibility of fungal pathogens. Our study evaluated the in vitro susceptibility of filamentous fungi isolated from patients with toenail onychomycosis against itraconazole, ciclopirox, eberconazole, fluconazole and terbinafine. The minimum inhibitory concentration (MIC) of these antifungal agents was determined with 100 isolates, including dermatophytes (70 strains) and non-dermatophyte molds (30 strains). The susceptibility of fungal isolates was measured by using a technique modified for dermatophytes (0.5 × 10(3)-0.5 × 10(4) conidia/ml as inocula) which followed the procedures described by the Antifungal Susceptibility Testing Subcommittee of the European Committee on Antimicrobial Susceptibility Testing (AFST-EUCAST) and the Clinical and Laboratory Standard Institute (CLSI M38-A). MIC ranges were 0.016-8.0 µg/ml for itraconazole, ciclopirox and eberconazole, 0.063-32.0 µg/ml for fluonazole, and 0.004-2.0 µg/ml for terbinafine. In vitro susceptibility tests indicated that eberconazole has a broad antimicrobial profile, including dermatophytes, as well as other filamentous fungi. Terbinafine was active (0.016-0.250 µg/ml) against dermatophytes.
