Cierre dinámico y toxina botulínica: una alternativa novedosa para el cierre definitivo del abdomen abierto y contenido / Dynamic closure system and botulinum toxin: a novel alternative for definitive closure of open abdomen

RESUMEN Se presenta el caso de un paciente masculino de 54 años que, cursando internación por neumonía- COVID-19, intercurrió con shock séptico por diverticulitis aguda Hinchey IV, por lo que se realizó cirugía de Hartmann. Evolucionó con isquemia colónica, se realizó colectomía total y abdomen abierto y contenido (AAyC). El manejo del AAyC se realizó con sistema de vacío (VAC) durante 7 semanas, resultando un AAyC tipo IIIa (Björck) con un gap de 16 cm. Se decidió iniciar, una vez dadas las condiciones clínicas del paciente, el cierre dinámico (CD) con tracción fascial con malla de polipropileno asociado a inyección de toxina botulínica (TB). Esta estrategia permitió el cierre fascial primario (CFP) de la pared abdominal en la quinta semana de comenzado el tratamiento, evitando de esta manera la morbilidad de un cierre por segunda intención.

ABSTRACT We report the case of a 54-year-old male patient hospitalized for COVID-19 pneumonia who developed septic shock due to acute Hinchey IV diverticulitis and required Hartmann's surgery. The patient evolved with colonic ischemia and underwent total colectomy and open abdomen (OA) with temporary abdominal closure (TAC) that was managed with a vacuum-assisted wound closure (VAWC) system for 7 weeks, resulting in a Björck grade 3A OA with a 16-cm gap. As he had a favorable clinic course, dynamic closure with mesh-mediated fascial traction was decided, associated with botulinum toxin (BT) injection. This strategy allowed primary fascial closure (PFC) of the abdominal wall 5 weeks after treatment was initiated, thus avoiding the complications of healing by secondary intention.

Resultados de la utilización de malla única en la reparación laparoscópica transabdominal (TAPP) de hernias inguinales bilaterales directas / Outcomes of laparoscopic transabdominal (TAPP) inguinal hernia repair with single mesh in bilateral direct inguinal hernias

RESUMEN Antecedentes: La cirugía laparoscópica presenta ventajas que son claramente observadas en la reparación de hernias bilaterales y recidivadas. El uso de una malla única como alternativa en la reparación de las inguinales bilaterales laparoscópicas con técnica transabdominal (TAPP) puede reducir el índice de recidivas y las chances de dolor crónico. Objetivo: describir y analizar los beneficios del uso de una malla única en el tratamiento de las hernias inguinales bilaterales con técnica TAPP. Material y métodos: análisis retrospectivo de hernioplastias inguinales laparoscópicas directas o mixtas operadas por vía transabdominal con malla única, efectuadas en pacientes con hernias inguinales bilaterales. Resultados: entre enero de 2016 y enero de 2017 se operaron 177 pacientes con hernia inguinal. Noventa y tres (93) pacientes presentaron hernias bilaterales, de las cuales 39 fueron operadas mediante el uso de la técnica con malla única, incluidas en este estudio. Conclusión: la utilización de una malla única es una alternativa segura en el tratamiento de las hernias inguinales bilaterales directas o mixtas operadas por vía laparoscópica con técnica TAPP.

ABSTRACT Background: The laparoscopic approach has clear advantages for repairing bilateral hernias and recurrent hernias. The use of a single mesh as an option in the laparoscopic treatment of direct bilateral inguinal hernias with the transabdominal preperitoneal (TAPP) technique, may reduce the recurrence rate and chronic pain. Objective: The aim of this study is to analyze the benefits of single mesh for the treatment of bilateral inguinal hernias with the TAPP technique. Material and methods: We conducted a retrospective analysis of patients with bilateral direct inguinal hernias undergoing laparoscopic hernia repair with the TAPP technique using a single mesh. Results: Between January 2016 and January 207 177 patients underwent inguinal hernia repair. Of the 93 patients with bilateral hernias, a single mesh was used in 39, which were included in this study. Conclusion: The use of a single mesh is a safe option for the laparoscopic treatment of direct bilateral inguinal hernias with the TAPP technique.

Cost-effectiveness of Platelet-Rich Plasma for Diabetic Foot Ulcer in Spain.

This study evaluated the cost-effectiveness of platelet-rich plasma (PRP) added to usual care versus usual care alone in elderly patients with chronic diabetic foot ulcer (DFU) from the Spanish health care system perpective. A 6-state Markov model with 3-month cycles was used to estimate costs and outcomes of wound healing and risk of recurrences, infections, and amputations over 5 years. Three treatment strategies were compared: (a) usual care plus PRP obtained with a commercial kit, (b) usual care plus PRP obtained manually, and (c) usual care. Data on effectiveness were taken from a recent meta-analysis. Outcomes and costs were discounted at 3% and resources were valued in 2018 euro. Compared with usual care, the PRP treatment with the manual method was more effective and less costly (dominant option), whereas the PRP treatment with the commercial kit was more effective but also more costly, with the incremental ratio being above the cost-effectiveness threshold (€57 916 per quality-adjusted life year). These results are sensitive to the price of PRP kits (a 20% discount would make the PRP treatment a cost-effective option) and effectiveness data, due to the heterogeneity of primary studies. In conclusion, PRP treatment for DFUs could be considered a cost-effective or even cost-saving alternative in Spain, depending on the method of obtaining the PRP. Despite the dominance of the manual method, its general use is limited to hospitals and specialized centers, whereas PRP kits could be used in primary care settings, but their prices should be negotiated by health authorities.

The definition, screening, and treatment of postpartum anemia: A systematic review of guidelines.

BACKGROUND: Postpartum anemia can negatively affect maternal health and interfere with early parenting. Thus, it is important to have clear, evidence-informed recommendations on its diagnosis and treatment. OBJECTIVE: To compare global recommendations regarding the appropriate management of postpartum anemia and to highlight similarities and differences. METHODS: Systematic searches were conducted in the databases PubMed, CINAHL, LILACS, TRIP database, and Scopus, and in the websites of health institutions and scientific societies. Search terms were related to anemia and the postpartum period. Two hundred and eighty papers were identified; the full texts of 30 sets of guidelines were reviewed, with seven being included in the final analysis. Recommendations were extracted through an evaluation of the evidence on the definition, screening, and diagnosis of anemia. The quality of the guidelines was assessed using the AGREE II instrument. RESULTS: Two sets of guidelines have been elaborated by international organizations, and the rest were produced by professional associations within high-resource countries. The discrepancies found in the guidelines are important and affect the definition of anemia, the criteria for screening asymptomatic women, or the criteria guiding treatment. The quality of the guidelines commonly scored between 4 and 6 on a scale of 0 to 7. Recommendations with poor-quality evidence predominated over recommendations with high-quality evidence. CONCLUSIONS: This review highlights the need to reach a consensus on the definition of postpartum anemia, to agree on what constitutes a problem for maternal health, and to provide recommendations that reach greater consensus on its diagnosis and treatment.

Platelet-rich plasma for the treatment of diabetic foot ulcers: A meta-analysis.

Foot ulcer is a major complication of diabetes mellitus and often precedes leg amputation. Among the different methods to achieve ulcer healing, the use of platelet-rich plasma, which is rich in multiple growth factors and cytokines and may have similarities to the natural wound healing process, is gaining in popularity. A systematic review with meta-analyses was performed to evaluate the safety and clinical effectiveness of platelet-rich plasma for the treatment of diabetic foot ulcers compared to standard treatment or any other alternative therapy. The electronic databases Medline, EMBASE, CINAHL, and Cochrane Central Register of Controlled Trials were consulted in March 2017 with no restrictions placed on the publication date. Predefined criteria were used to determine inclusion of studies and to assess their methodologic quality. Eight randomized clinical trials and two prospective longitudinal-observational studies with control group were included. Platelet-rich plasma treatment increased the likelihood of chronic wound healing (RR = 1.32; 95% CI: 1.11, 1.57, I2 = 15%) while the volume of the ulcer (MD = 0.12 cm2 ; 95% CI: 0.08, 0.16; p < 0.01; I2 = 0%) and time to complete wound healing (MD = -11.18 days; 95% CI: -20.69, -1.68; I2 = 53%) decreased. Regarding safety profile, platelet-rich plasma did not differ from standard treatment in terms of probability of occurrence of wound complications (RR = 0.57; 95% CI: 0.25, 1.28; I2 = 0%) or recurrences (RR = 2.76; 95% CI: 0.23, 33.36; p = 0.43; I2 = 82%) but it decreased the rate of adverse events (RR = 0.80; 95% CI: 0.66, 0.96; p = 0.02; I2 = 0%). Cumulative meta-analysis revealed that there is enough evidence to demonstrate a statistically significant benefit. However, studies included presented serious methodologic flaws. According to the results, platelet-rich plasma could be considered a candidate treatment for nonhealing of diabetic foot ulcers.

Spectrofluorimetric and micelle-enhanced spectrofluorimetric determination of gatifloxacin in human urine and serum.

A spectrofluorimetric method to determine gatifloxacin has been developed and applied to the quantification of this fluoroquinolone in spiked human urine and serum. The native fluorescence of gatifloxacin allow the determination of 0.040-0.700 micro gmL(-1) of this molecule in aqueous solution containing acetic acid-sodium acetate buffer (pH 3.5), with lambda(exc)=292 nm and lambda(em)=484 nm. Micelle-enhanced fluorescence led to 75% higher analytical signals in presence of 12 mM sodium dodecyl sulphate, which allow the determination of 0.020-0.450 microg mL(-1) fluoroquinolone with lambda(exc)=292 nm and lambda(em)=470 nm. Both methods were successfully applied to gatifloxacin determination in spiked human urine and serum.
