Initial results of the implementation of an ambulatory mini percutaneous nephrolithotomy program.

OBJECTIVE: To present our program for ambulatory mini percutaneous nephrolithotomy (mini-PCNL) and evaluate its initial results. MATERIAL AND METHODS: We analyzed the implementation of the protocol into the clinical practice with the first 30 outpatient mini-PCNL cases performed in our center between April 2021 and September 2022. Demographic characteristics, perioperative variables, complications and need for unplanned health care, stone-free rate (SFR), stone type and patient satisfaction with the major ambulatory surgery (MAS) process were collected. RESULTS: A total of 30 patients with a mean age of 60.2 ±â€¯11.6 years who met the inclusion criteria underwent surgery. The mean stone size was 15 mm [range: 5-20]. No intraoperative complications were recorded. All patients except one were discharged the same day of surgery as planned. In the month following discharge, the rate of complications, emergency department (ED) revisits or hospital readmissions rates were 0%. Stone-free-rate (SFR) at 3 months was 83%. Overall satisfaction with the whole perioperative process was assessed with the EVAN-G questionnaire, obtaining 124.3 points out of a maximum of 150, which is equivalent to a 78.6% level of satisfaction. CONCLUSION: Ambulatory mini-PCNL can be implemented as a treatment option in centers with experience in endourology, an established MAS Unit, and strictly selected patients. Our initial results show an adequate safety profile and high overall satisfaction perceived by patients undergoing the ambulatory approach.

Occurrence of hydrodynamic cavitation.

In this paper, the conditions under which cavitation (or liquid film rupture) can or cannot occur in thin layers of moving liquid are derived for three typical cases. At the same time, expressions depending on geometrical and movement parameters, where cavitation might start, are given. The results are obtained using simple engineering terms, which can be used in cases whether it is necessary to avoid cavitation or to induce it.

[Quality of home medication collection in the Emergency Department: reconciliation discrepancies]. / Calidad de la recogida de la medicación domiciliaria en urgencias: discrepancias en la conciliación.

INTRODUCTION: The objective of the study was to assess home medication data collected at the Emergency Department in a tertiary hospital. It also aimed to identify whether any possible deficiencies in this collection were translated as reconciliation errors on admission, to analyse and classify these data and identify the pharmacological groups involved. METHOD: A prospective observational study was carried out which analysed the pharmacotherapeutic data collected at the Emergency Department. Patients who were admitted to the Pneumology and Internal Medicine wards at the Miguel Servet University Hospital in Zaragoza were included. A list of the home drugs taken before the hospital stay was compiled, assessing whether the quality deficiencies in data collected in the emergency department translated as reconciliation errors at admission. Unjustified discrepancies were considered and classified in line with the criteria of the consensus document on terminology, classification and assessment of the drug reconciliation programmes for 2009. RESULTS: We included 136 patients, finding reconciliation errors in 86.8%. The total number of reconciliation errors found was 519. The most frequent types were: omitting a drug, missing dose information, missing administration frequency information. Almost 40% of the reconciliation errors found in the Internal Medicine ward were not resolved, which was double that of the Pneumology ward. Most discrepancies were found for the Digestive System and Metabolism group (24%). CONCLUSIONS: The percentage of patients that experienced reconciliation errors was high (86%), observing an important opportunity to improve at patient admission to the Emergency Department.

Hemorrhagic complicationes after percutaneous nephrolithotomy: The importance of an early endovascular management. / Complicaciones hemorrágicas de la nefrolitotomía percutánea: valor del tratamiento endovascular precoz.

INTRODUCTION AND OBJECTIVES: Hemorrhage due to arteriovenous fistula (AVF) or pseudoaneurysm (PA) is a rare complication after percutaneous nephrolithotomy (PCNL). The objective of this study is to evaluate hemorrhagic complications (HC) after PCNL and the results of their endovascular treatment. MATERIALS AND METHODS: Between May 2009 and December 2019, 1335 PCNL were performed in our center for kidney stone disease. We analyzed the incidence of early and late HC, their management, the need for subsequent embolization, as well as clinical and analytical data of these patients. RESULTS: A total of 59 (4.4%) patients presented HC. Bleeding was managed with arteriography and selective embolization (ASE). Perirenal hematoma was seen in 38 patients (64%). Regarding angiographic findings, there were 32 (54%) PA, 8 (14%) AVF, 4 (7%) extravasations due to vascular laceration and 15 (25%) PA combined with AVF. In one case, 3 procedures were required to control the bleeding. In 30 patients (51%) blood transfusions were not necessary, while in 29 (49%), a mean of 1.3 units were transfused. Median follow-up was 24±21 months. Mean time interval between PCNL and ASE was 7.3±4.9 days. A total of 24 (41%) patients were readmitted after discharge due to late HC requiring ASE. Delay between readmission and ASE was 4.8±4.6hours in average. CONCLUSION: Early and late HC after PCNL can be severe. Rapid identification and treatment with ASE is an effective and minimally invasive and avoids multiple blood transfusions which in many cases constitute an insufficient treatment.

[Intracavernosal methoxamine self-injection for the treatment of low-flow recurrent priapism]. / Tratamiento del priapismo recurrente de bajo flujo mediante autoinyección intracavernosa domiciliaria de metoxamina.

We report the case of a young man with a recurrent idiopathic priapism, successfully treated with methoxamine intracarvenosal self-injections. The patient was instructed in intracorporeal self-injection of this pure alpha-1 adrenergic agonist, which provided complete detumescence. The patient became asymptomatic after one month of domiciliary treatment. We conclude that intracavernosal self-administered methoxamine can be a useful treatment of recurrent idiopathic priapism.

Brûlologie et médecine légale: les victimes d'incendie.

During a judicial inquiry, the forensic doctor is frequently required to examine the hospitalized fire victim. He has to produce a certificate on the burns, defining their origin, seriousness and prognosis. The expert assessment of serious burn victims consists in an overall evaluation of functional and psychological sequelae, and can be conducted only after the long period of treatment needed for them to heal. The expert must know the forensic rules concerning the specific features of sequelae that follow a cutaneous burn injury. The forensic doctor can intervene where a body is discovered, and the aim of the autopsy is to check if burns were the cause of death. The most common lesions observed are serious thermal burns and they are frequently associated with inhalation of fumes. Often the body is carbonized to conceal a homicide therefore it is crucial that postmortem results are compared with the police investigation data. Due to modifications to the body brought about by fire and charring, a specific protocol for identification is required, especially in the event of a disaster.

[Incomplete urethral duplication]. / Duplicidad uretral incompleta.

Urethral duplicity is a rare congenital malformation. We report a case of one 25 years old male suffering recurrent urinary infections. The diagnostic of uncompleted urethral duplicity was performed by retrograde urethrography and micturating cystourethrogram. The accessory channel was excised by a perineal approach. Clinical results were satisfactory, remaining an asintomatic patient two years after surgery, with normal mictional behavior.

Fibrosarcoma of the head and neck.

Fourteen adult patients with fibrosarcoma of the head and neck were treated by the Division of Surgical Oncology at the University of Illinois and Cook County Hospitals. All patients had a mass in the head and neck area, and four patients (29%) had tumors in a burn scar or in a field of irradiation. The 2-, 5-, and 10-year disease-free rates were 57%, 57%, and 50%, respectively, with overall survivals of 79%, 71%, and 57%, respectively. The median survival was significantly higher for patients with low-grade tumors than for patients with high-grade lesions (P < 0.05). Wide surgical excision was the mainstay of therapy, with re-excision considered for some patients with locally recurrent disease. Aggressive treatment can afford fibrosarcoma patients good long-term therapeutic results.

[The role of the radiologist in the medicolegal procedure after an aviation accident]. / Rôle du radiologiste dans l'enquête médico-légale après une catastrophe aérienne.

The role of radiologic imaging studies in the forensic medical procedure following an airborne disaster is now well established. This report summarizes the experience and the results acquired with a recent air crash, and insists on three suggestions: the necessity of a prepared identification team consisting of specialist in forensic medicine, in forensic odontology and specialist in forensic radiology, and the usefulness of a suitable structure for the study and the storage of the dead bodies, the need for a compilation of radiological informations, notably dental X-Ray examinations for the flying personnel.

[Radiology in the medicolegal identification of cadavers. A new technique of radiography of the maxilla]. / Apports de la radiologie pour l'identification médico-légale des corps. Une technique nouvelle de radiographie des maxillaires.

After removal, the maxilla and the mandible are placed on a standard radiologic cassette and a X-ray is performed with a low energy beam. Different views can be obtained if required. These radiographic images provide a complete, permanent and detailed record of dental anatomy and restorations, for comparison with antemortem radiographies. Two examples are provided. Moreover, this technique enables the determination of the dental age of children.

XML-based synchronization of mobile medical devices.

Today, mobile computing provides enough resources to be used in medical applications. Patient treatment is a process that involves multiple partners. All those partners need access to common patient-data and need to make changes to the patients' health record. Therefore, data that the partners collect and change with mobile devices has to be synchronized on a central server to form the master patient record. Data conflicts resulting from the synchronization have to be solved automatically. Our project describes a solution for XML-based data replication and synchronization for mobile health applications.

[Intravenous drugs infusion safety through smart pumps]. / Seguridad en la administración intravenosa de medicamentos mediante bombas de infusión inteligentes.

OBJECTIVE: To analyze the role of smart infusion pumps in reducing errors related with the administration of intravenous medications. METHOD: Retrospective, observational study analyzing the implementation of a system with smart intravenous infusion pumps (Hospira MedNetTM) and the role of the safety system for the detection of errors during the administration of drugs, sera, and blood. We included infusions administered at the day-care hospitals of hematology, oncology, rheumatology, and oncopediatrics. We analyzed adherence to the safety system, the number of programming errors detected, the commonly implicated drugs in these errors, and improvement actions. RESULTS: During the study period, 120 smart pumps were implemented and data on 70,028 infusions were gathered. The rate of adherence to the safety program was 62.30% in hematology (6,887 infusions), 60,30% in oncology (28,127 infusions), 46,50% in rheumatology (1,950 infusions) and 1.8% in oncopediatrics (139 infusions). 3,481 out of the established limits programming alerts were generated by the pumps: 2,716 of relative limit and 765 of absolute limit. En 807 infusions (2.17%), errors that could have had consequences for the patients could be prevented. These findings allowed implementing a series of strategies aimed at minimizing these errors in the future. CONCLUSIONS: The Hospira MedNetTM system detects deviations from the established protocols of intravenous infusion, preventing in this way potential adverse events for the patients. It also allows establishing correction measures and implementing the improvement strategies.

Flexible Ureteroscopy as a Major Ambulatory Surgery Procedure. Single Center Experience and Analysis of Variables Related to Hospital Readmission

Objective: To assess our experience in flexible ureteroscopy (fURS) in major ambulatory surgery (MAS) and to detect variables related to unplanned medical assistance after surgery. Material & Methods: We conducted a retrospective study among patients with renal stones undergoing a fURS from 2014 to 2019 in MAS at our hospital. Variables: Age, gender, ASA physical status, type of anesthetic technique performed, stone characteristics, influence of double J stent before or after surgery, and postoperative complications according to the Clavien-Dindo modified classification. We evaluated variables related to hospital readmission or visit to the emergency room after surgery. Results: A total of 222 consecutive fURS for stone disease were performed in MAS. Patients’ average age was 52.9 ± 13.91 years old. The mean operating time was 57.86 ± 21.11 minutes. The mean stone size was 1.92 ± 1.43 with a diameter of 10.01 ± 4.24 mm. 47.3% of patients had a double J stent before fURS, and in 35.14% of cases, a stent was placed after surgery. 7.65% of patients required unplanned hospitalization. 14.86% of patients presented to the emergency room in the following month after surgery. Among them, one-third consulted for symptoms related to the double J. Patients who carried a double J stent before the fURS had 64% less risk of visiting the emergency department in the following month after surgery [OR = 0,363; IC95% (0.153-0.798)]. All other variables (age, gender, operating time...) did not modify the risk of unplanned medical assistance. Conclusion: The low complication rate following flexible ureteroscopy allows its performance as an ambulatory surgery. Patients who carry double J stent before the procedure have less risk of requiring unplanned medical assistance after the surgery (AU)

Complicaciones hemorrágicas de la nefrolitotomía percutánea: valor del tratamiento endovascular precoz / Hemorrhagic complicationes after percutaneous nephrolithotomy: The importance of an early endovascular management

Introducción y objetivos: La hemorragia secundaria a la fístula arteriovenosa (FAV) o al pseudoaneurisma (PA) es una complicación poco frecuente de la nefrolitotomía percutánea (NLPC). El objetivo de este estudio es evaluar las complicaciones hemorrágicas (CH) tras la NLPC y los resultados del tratamiento endovascular.Materiales y métodosEntre mayo de 2009 y diciembre de 2019 se realizaron en nuestro centro 1.335 NLPC por litiasis renal. Analizamos la incidencia de CH tempranas y tardías, el tratamiento administrado, la necesidad de embolización posterior y los datos clínicos y analíticos de los pacientes.ResultadosUn total de 59 (4,4%) pacientes presentaron CH, y todos fueron tratados con arteriografía y embolización selectiva (AES) para controlar el sangrado. Se observó hematoma perirrenal en 38 pacientes (64%).En cuanto a los hallazgos angiográficos, hubo 32 (54%) PA, 8 (14%) FAV, 4 (7%) extravasaciones por laceración vascular y 15 (25%) PA combinadas con FAV. En un caso, fueron necesarios 3 procedimientos para controlar la hemorragia. En 30 pacientes (51%) no se requirió transfusión de sangre, mientras que en 29 (49%) se transfundió una media de 1,3 unidades. La mediana de seguimiento fue de 24±21 meses.El intervalo de tiempo medio entre la NLPC y la AES fue de 7,3±4,9 días. Un total de 24 (41%) pacientes reingresaron tras el alta debido a una CH tardía que requería AES. La demora entre el reingreso y la AES fue de 4,8±4,6horas de media.ConclusiónLas CH tempranas y tardías tras la NLPC pueden ser mayores. El tratamiento con AES tras la detección precoz es un método efectivo y mínimamente invasivo que evita múltiples transfusiones de sangre, en muchos casos insuficientes. (AU)
