RESUMEN
PURPOSE: Gastrointestinal mesenchymal tumors (GMTs) include malignant, intermediate malignancy, and benign lesions. The aim is to propose a new surgical classification to guide the intraoperative minimally invasive surgical strategy in case of non-malignant GMTs less than 5 cm. METHODS: Primary endpoint is the creation of a classification regarding minimally invasive surgical technique for these tumors based on their gastric location. Secondary endpoint is to analyze the R0 rate and the postoperative morbidity and mortality rates. Tumors were classified in two groups based on their morphology (group A: exophytic, group B: transmural/intragastric). Each group is then divided based on the tumor location and consequently surgical technique used in subgroup: AI (whole stomach area) and AII (iuxta-cardial and pre-pyloric areas) both for the anterior and posterior gastric wall; BIa (greater curvature on the anterior and posterior wall), BIb (lesser curvature on the anterior wall); BII (iuxta-cardial and pre-pyloric area in the anterior and posterior wall, including the lesser curvature on the posterior wall). RESULTS: Forty-two patients were classified and allocated in each subgroup: 17 in AI, 2 in AII, 5 in BIa, 3 in BIb, and 15 in BII. Two postoperative Clavien-Dindo I complications (4.8%, subgroup BIa and BIb) occurred. One patient (2.4%, subgroup AI) underwent reintervention due to R0 resection. CONCLUSIONS: This classification proved to be able to classify gastric lesions based on their morphology, location, and surgical treatment, obtaining encouraging perioperative results. Further studies with wider sample of patients are required to draw definitive conclusions.

Objectives: To describe the complications associated with the different gastrostomy techniques [endoscopic (PEG), radiologic (PRG), and surgical (SG)] performed in the last 26 years in a terciary hospital. Methods: Retrospective observational study. Patients who underwent gastrostomy at the Virgen del Rocío University Hospital between 1995 and 2021 were included. For PEG, the PULL technique was performed until 2018 and subsequently the PUSH technique predominantly. For PRG, a pigtail catheter was used until 2003, a balloon catheter between 2003 and 2009, and a balloon catheter with gastropexy between 2015 and 2021. For SG, the conventional technique (CSG) was performed until 2009 and since then the laparoscopic assisted percutaneous gastrostomy (PLAG) technique. Descriptive analysis was performed obtaining the median and quartiles of the quantitative variables [P50 (P25-P75)] and the frequency for the qualitative variables [n (%)].The comparison of complications between patients who underwent different techniques was performed with Fisher's test. Results: n = 1,070 (PEG = 608, PRG = 344, SG = 118). The three most frequent indications were head and neck tumors, neurological diseases and gastroesophageal tumors. The percentage of patients who had any complication was 48.9% (PEG-PULL), 23.7% (PEG-PUSH), 38.5% (pigtail PRG), 39.2% (balloon PRG), 29.7% (balloon with gastropexy PRG), 87.3% (CSG), and 41.26% (PLAG). 2 (0.18%) patients died from gastrostomy-related complications. 18(1.68%) presented with peritonitis and 5 (0.4%) presented with gastrocolic fistula. The rest of the complications were minor. Conclusion: Gastrostomy in any of its modalities is currently a safe procedure with a low rate of complications, most of which are minor.
RESUMEN
We report the case of a 53-year-old man with psoriatic arthritis, suffering from a malignant and recidivant myoepithelioma in his right axilla and arm, and undergoing two surgeries, with the last one being performed a month prior to actual admission. After the last surgery, he was admitted to hospital with fever without a source. After physical examination, laboratory tests, blood cultures and transthoracic and transesophageal echocardiography, he was diagnosed with infectious endocarditis (IE) on a bicuspid aortic valve (BAV) caused by Pseudomona aeruginosa (PA). Antibiogram-guided antibiotic therapy with meropenem and tobramicin was initiated. However, in the presence of repetitive spleen infarctions and a large vegetation, 12 days after admission, a bioprosthesis aortic valve implantation was performed. The postsurgical evolution was favorable and prolonged antibiotic course with meropenem and tobramicin was completed. The pathological anatomy and the native valve cultured confirmed an IE caused by PA. Gram-negative non-HACEK IE cases are infrequent, accounting for 1.8% of the total IE cases. PA is the second most frequent bacillus in this group, causing endocarditis more prevalently when associated with healthcare procedures rather than injectable drug use. No prior case study has identified IE caused by PA related to a BAV in the last years.
RESUMEN
Blood culture negative endocarditis (BCNE) is frequent in infective endocarditis (IE). One of the causes of BCNE is fastidious microorganisms, such as Bartonella spp. The aim of this study was to describe the epidemiologic, clinical characteristics, management and outcomes of patients with Bartonella IE from the "Spanish Collaboration on Endocarditis-Grupo de Apoyo al Manejo de la Endocarditis infecciosa en España (GAMES)"cohort. Here we presented 21 cases of Bartonella IE. This represents 0.3% of a total of 5590 cases and 2% of the BCNE from the GAMES cohort. 62% were due to Bartonella henselae and 38% to Bartonella quintana. Cardiac failure was the main presenting form (61.5% in B. hensalae, 87.5% in B. quintana IE) and the aortic valve was affected in 85% of the cases (76% in B. henselae, 100% in B. quintana IE). Typical signs such as fever were recorded in less than 40% of patients. Echocardiography showed vegetations in 92% and 100% of the patients with B. henselae and B. quintana, respectively. Culture was positive only in one patient and the remaining were diagnosed by serology and PCR. PCR was the most useful tool allowing for diagnosis in 16 patients (100% of the studied valves). Serology, at titers recommended by guidelines, only coincided with PCR in 52.4%. Antimicrobial therapy, in different combinations, was used in all cases. Surgery was performed in 76% of the patients. No in-hospital mortality was observed. One-year mortality was 9.4%. This article remarks the importance for investigating the presence of Bartonella infection as causative agent in all BCNE since the diagnosis needs specific microbiological tools and patients could benefit of a specific treatment.
RESUMEN
OBJECTIVES: The aims of this study were to describe patients' experiences after single-tablet regimen (STR) desimplification and its impact on self-reported treatment adherence and quality of life. METHODS: We performed a survey among all patients from the multicenter cohort of the Spanish HIV/AIDS Network who had desimplified the STRs dolutegravir/abacavir/lamivudine (DGT/ABC/3TC) or rilpivirine/tenofovir disoproxil fumarate/emtricitabine to their separate components (DTG + generic ABC/3TC or RPV + generic TDF/FTC) between December 2016 and November 2018. RESULTS: Among 216 patients who fulfilled inclusion criteria, 138 (63.9%) completed the questionnaire. Most of the patients (78.3%) knew what generic drugs are, only 8.7% believed that treatment with 2 pills is less effective than treatment with an STR, and 67.4% agreed that it is reasonable to take 2 pills instead of 1 for HIV treatment to decrease costs for the health care system. After desimplification, 13.0% of the patients stated they had more secondary effects, 8.0% had forgotten one or more doses more frequently than before, and 10.9% had sometimes forgotten to take 1 pill, but not the other. A proportion of 30.4% reported not being happy to take more pills a day, and 10.1% experienced a worse quality of life after the treatment desimplification. CONCLUSIONS: After STR desimplification, most of the patients had a fair knowledge about generic antiretrovirals, and they agreed to desimplify their STR to decrease costs. Although almost a third of the respondents were not happy to take 2 pills a day, only a minority reported worse adherence or quality of life.

The elite controller (EC)-long term non-progressor (LTNP) phenotype represent a spontaneous and advantageous model of HIV-1 control in the absence of therapy. The transcriptome of peripheral blood mononuclear cells (PBMCs) collected from EC-LTNPs was sequenced by RNA-Seq and compared with the transcriptomes from other phenotypes of disease progression. The transcript abundance estimation combined with the use of supervised classification algorithms allowed the selection of 20 genes and pseudogenes, mainly involved in interferon-regulated antiviral mechanisms and cell machineries of transcription and translation, as the best predictive genes of disease progression. Differential expression analyses between phenotypes showed an altered calcium homeostasis in EC-LTNPs evidenced by the upregulation of several membrane receptors implicated in calcium-signaling cascades and intracellular calcium-mobilization and by the overrepresentation of NFAT1/Elk-1-binding sites in the promoters of the genes differentially expressed in these individuals. A coordinated upregulation of host genes associated with HIV-1 reverse transcription and viral transcription was also observed in EC-LTNPs -i.e. p21/CDKN1A, TNF, IER3 and GADD45B. We also found an upregulation of ANKRD54 in EC-LTNPs and viremic LTNPs in comparison with typical progressors and a clear alteration of type-I interferon signaling as a consequence of viremia in typical progressors before and after receiving antiretroviral therapy.

INTRODUCCIÓN: El manejo de las bacteriemias por Klebsiella pneumoniae productora de carbapenemasa del tipo OXA-48 (KPOXA-48) es complicado por las escasas opciones terapéuticas y la elevada mortalidad. El objetivo del estudio fue describir las características clínicas de bacteriemia por KPOXA-48 entre octubre de 2013 y diciembre de 2016. MATERIAL Y MÉTODOS: Se recogieron retrospectivamente de las historias clínicas las variables para analizar. La producción de carbapenemasas se confirmó por métodos fenotípicos y moleculares. RESULTADOS: Se incluyeron 38 pacientes con bacteriemia, mayoritariamente de origen nosocomial (n = 31). Un alto porcentaje de las bacteriemias (n = 26) fueron secundarias, principalmente de origen urinario (n = 11). Todos los aislamientos eran multirresistentes con producción de la beta-lactamasa de espectro extendido CTX-M-15 y carbapenemasa del tipo OXA-48. La mortalidad bruta con antibioterapia dirigida adecuada fue del 0% y la inadecuada del 55% (p = 0,0015). CONCLUSIONES: Se pone de manifiesto la importancia de identificar este mecanismo de resistencia, los factores del paciente, el tipo de bacteriemia y la adecuación de la estrategia terapéutica en la evolución clínica
INTRODUCTION: Community-acquired Staphylococcus aureus (SA) bacteraemia is a common cause of hospitalisation in children. The occurrence of secondary foci (SF) of SA infection is associated with higher morbidity and mortality. OBJECTIVES: To identify risk factors for SF of infection in children with community-acquired SA bacteraemia. MATERIAL AND METHODS: Prospective cohort. All children aged from 30 days to 16 years admitted to a paediatric referral hospital between January 2010 and December 2016 for community-acquired infections, with SA isolated in blood cultures, were included. Microbiological, demographic and clinical characteristics were compared, with or without SF infection after 72 hours of hospitalisation. RESULTS: A total of 283 patients were included, 65% male (n = 184), with a median age of 60 months (IQR: 30-132). Seventeen per cent (n = 48) had at least one underlying disease and 97% (n = 275) had some clinical focus of infection, the most common being: osteoarticular 55% (n = 156) and soft tissue abscesses 27% (n = 79). A total of 65% (n = 185) were resistant to methicillin. A SF of infection was found in 16% of patients (n = 44). The SF identified were pneumonia 73% (n=32), osteoarticular 11% (n = 5), soft tissue 11% (n = 5) and central nervous system 5% (n=2). In the multivariate analysis, the persistence of positive blood cultures after the fifth day (OR: 2.40, 95%CI: 1.07-5.37, P < 0.001) and sepsis (OR: 17.23, 95%CI 5.21-56.9, P < 0.001) were predictors of SF. There was no association with methicillin sensitivity. CONCLUSIONS: In this cohort, methicillin-resistant SA infections predominated. The occurrence of SF of infection was associated with the persistence of bacteraemia after the fifth day and sepsis on admission

INTRODUCTION: Limited therapeutic options and high mortality make the management of OXA-48-like carbapenemase-producing Klebsiella pneumoniae (KPOXA-48) bacteraemia complicated. The aim of the study was to describe the clinical characteristics of KPOXA-48 bacteraemia between October 2013 and December 2016. MATERIAL AND METHODS: The variables to analyse were retrospectively collected from medical records. Carbapenemase production was confirmed by phenotypic and molecular methods. RESULTS: A total of 38 patients with bacteraemia were included, mainly classified as hospital-acquired (n=31). The majority of cases were secondary bacteraemia (n=26), most commonly arising from the urinary tract (n=11). All isolates presented a multidrug-resistant profile with the extended spectrum beta-lactamase CTX-M-15 and the carbapenemase OXA-48-like production. The crude mortality rate with adequate targeted antibiotic therapy was 0%, rising to 55% with inadequate treatment (p=0.0015). CONCLUSIONS: This study highlights the importance of identifying this resistance mechanism, the patient factors, type of bacteraemia and adequacy of antibiotic therapy in the outcome of bacteraemia.

Tropheryma whipplei endocarditis is an uncommon condition with very few series and <90 cases reported in the literature. The aim of the study was to analyze the epidemiological, clinical, and outcome characteristics of 17 cases of T. whipplei endocarditis recruited in our country from a multicentric cohort from 25 Spanish hospitals from the Spanish Collaboration on Endocarditis-Grupo de Apoyo al Manejo de la Endocarditis infecciosa en España.From a total of 3165 cases included in the cohort, 14.2% were diagnosed of blood culture negative endocarditis (BCNE) and 3.5% of these had T. whipplei endocarditis. This condition was more frequent in men. The average age was 60.3 years. Previous cardiac condition was present in 35.3% of the cases. The main clinical manifestation was cardiac failure (76.5%) while fever was only present in the 35.3%. Ecocardiography showed vegetations in 64.7% of patients. Surgery was performed in all but 1 cases and it allowed the diagnosis when molecular assays were performed. A broad range rRNA 16S polymerase chain reaction was used for first instance in all laboratories and different specific targets for T. whipplei were employed for confirmation. A concomitant Whipple disease was diagnosed in 11.9% of patients. All patients received specific antimicrobial treatment for at least 1 year, with no relapse and complete recovery.T. whipplei endocarditis is an uncommon condition with an atypical presentation that must be considered in the diagnosis of BCNE. The prognosis is very good when an appropriate surgical management and antimicrobial-specific treatment is given.

BACKGROUND: The current tendency to use increasingly less aggressive procedures has facilitated the development of new minimally invasive techniques. In this context, single-port (SP) access procedures can become an alternative to the conventional laparoscopic approach. METHODS: A total of 22 morbidly obese patients were submitted to pure SP Roux-en-Y gastric bypass without additional ports. Selection for this approach was based on distance from the xiphoid to the umbilicus less than 28 cm, body mass index (BMI) lower than 50 kg/m(2), and preferably peripheral obesity. Access to the cavity was obtained through a single transverse, transumbilical incision, with placement of a SILS Port device. RESULTS: The mean age of the patients was 41 ± 8.98 years, and 95 % of the patients were women. The mean BMI of the series was 42.68 ± 2.28 kg/m(2), and the mean body weight was 111.34 ± 10.66 kg. Surgery was performed successfully in all cases through a transumbilical incision with a mean length of 26.68 ± 5.27 mm. The mean surgical time was 114.05 ± 21 min, and the mean hospital stay was 3.27 ± 1.01 days. No intraoperative or immediate postoperative deaths or complications occurred. The median postoperative BMI during a mean follow-up period of 12 months was 28 kg/m(2) (range, 18-35 kg/m(2)). The median weight loss was 39 kg, and the percentage loss of excess body weight was 86 %. In relation to improvement of the comorbidities, two of the three patients with arterial hypertension showed normalization of their blood pressure values. Likewise, the blood glucose levels were corrected in two of the three diabetic patients, as well as in the patient with altered fasting blood glucose. CONCLUSIONS: Single-port Roux-en-Y gastric bypass surgery seems to be a safe, viable, and reproducible technique, but randomized studies involving larger patient series and longer follow-up periods are needed to compare the SP access and the multiple-port laparoscopic approach.

BACKGROUND: Seroma after laparoscopic ventral hernia repair (LVHR) has been related to certain complications of the technique, such as recurrences and postoperative pain. The aim of this study was to assess whether percutaneous application of fibrin sealant in the hernia sac after LVHR reduces the incidence and volume of the postoperative seroma, and to analyze whether the percentage of patients achieving complete normalization of the abdominal wall increases. METHODS: Prospective and comparative study. Patients were distributed into 2 control-case groups. Group 1 comprised patients submitted to LVHR using the double crown technique and a compressing bandage as the only method for prevent seroma. Group 2 comprised patients admitted to LVHR using the same technique together with percutaneous injection of fibrin sealant in the sac, and later applying the same bandage. Patients were examined clinically and radiologically at 7 days, 1 month, and 3 months after surgery. RESULTS: Twenty-five patients were included in each group. There were significant differences in the incidence of seroma by the day 7 after surgery (92% in group 1 vs. 64 % in group 2, p = 0.017) and by 1 month (72% in group 1 vs. 28% in group 2, p = 0.002). The difference was also significant regarding the achievement of normalization of the abdominal wall by day 7 (24% in group 1 vs. 52% in group 2, p = 0.041) and by month 1 (64% in group 1 vs. 88% in group 2, p = 0.047) after operation. Volume of seroma was larger among patients of group 1 after the week (p = 0.002) and 1 month after operation (p = 0.001). CONCLUSIONS: Fibrin sealant application after LVHR reduces the incidence and volume of the seroma 7 days and 1 month after surgery. The treated patients obtain a larger normalization of the abdominal wall 1 week and 1 month after the operation.

BACKGROUND: Sleeve gastrectomy is a recent, purely restrictive procedure in bariatric surgery that has shown results similar to gastric bypass over the short and middle term. At the same time, single-port access surgery has fostered the development of new techniques and methods seeking better cosmetic results and less postoperative pain, while maintaining the satisfactory results obtained by the standard laparoscopic approach. One of the problems associated to single-access surgery is the lack of traction and the difficulties to retract the liver. The authors' aim was to try to avoid additional trocars or sutures in order to perform pure single-incision surgery, using 2 magnetic forceps. METHODS: The authors present the case of a 51-year-old morbidly obese female (body mass index = 44.82) who underwent a pure single-access laparoscopic sleeve gastrectomy with no additional trocars or sutures and assisted by 2 neodymium magnetic forceps: one to retract the liver and the other to retract the stomach in order to provide sufficient triangulation for adequate exposure of the surgical field during dissection. RESULTS: The procedure was completed in 120 minutes. No preoperative or postoperative complications were recorded, and the patient was discharged 2 days after surgery. CONCLUSION: Single-port access sleeve gastrectomy assisted by magnetic forceps is feasible and safe in the hands of experienced laparoscopic surgeons, solving one of the problems associated to this type of surgery, that is, the need for an additional trocar and needles or sutures to retract the liver and stomach in order to perform the operation.

Single port laparoscopic surgery is becoming an alternative to conventional laparoscopic surgery as a new approach where all the conventional ports are gathered in just one multichannel port through only one incision. Appling this technical development, we have developed a new technique based on an intragastric approach using a single port device assisted by endoscopy (I-EASI: intragastric endoscopic assisted single incision surgery) in order to remove benign gastric lesions and GIST tumors placed in the posterior wall of the stomach or close to the esophagogastric junction or the gastroduodenal junction. We present a patient with a submucosal gastric tumor placed near the esophagogastric junction removed with this new approach.
