Long-Term Outcomes of Tension-Free Vaginal Tape Procedures in Argentine Women: Our First Report After 20 Years.

Introduction And Hypothesis: Transvaginal tape is currently a stress urinary incontinence (SUI) treatment with recommendation grade A in accordance with the 7th International Consultation on Incontinence. The main aim of the present study was to evaluate objective and subjective outcomes of tension-free vaginal tape (TVT) 20 years after our medical group started to use it. A second aim was to describe the voiding phase and the immediate, medium-term, and late complications of TVT procedures.

Hysteroscopic subchorionic injection of methotrexate followed by laparoscopic excision of the gestational sac for the management of cesarean scar ectopic pregnancy: an innovative dual approach of a challenging pathology.

Objective: To describe an effective two-step surgical approach for the management of cesarean scar ectopic pregnancies (CSEPs). CSEPs occur at an estimated frequency of 1 in 1,800 pregnancies, constituting approximately 6% of ectopic pregnancies in women with a history of prior cesarean delivery [1, 2]. Despite numerous recommended therapeutic approaches, the most effective treatment strategy remains uncertain [3].

[Don Quixote de la Mancha and the description of biphasic sleep in Spanish literature].

Introduction: Biphasic or segmented sleep is the habit of sleeping a first and a second sleep separated by a watching. The historian A Ekirch found that this was how people slept in pre-industrial times before the powerful artificial lighting. He is based on texts in different languages, from Antiquity to the 20th century, but the absence of sources in Spanish is striking.

[Optimization in the detection of bacteremia: Integrated use of FilmArray (BCID2) and MALDI-TOF].

The usefulness of the combined use of MALDI-TOF MS from a subculture with 3-5h of incubation and the BCID2 panel (FilmArray) for the identification of microorganisms from positive blood cultures and its importance in the adjustment of antimicrobial therapy was analyzed. Overall identification with BCID2 was 90.4% (142/157) and with Maldi-TOF MS 83.

[Study of an ocular ptosis in a 13th century illuminated manuscript].

Introduction: The finding of an eyelid ptosis in a manuscript of the xiii century raises the differential diagnosis of injury to the third cranial nerve. This nerve was not differentiated from the other oculomotors until the xvi century and only in the xix century a clinicopathological correlation was established for its paralysis.

Aim: Describe the characteristics and differential diagnoses of an eyelid ptosis illustrated in the Book of Divine Works (1173) by Hildegard of Bingen.

A poor and delayed anti-SARS-CoV2 IgG response is associated to severe COVID-19 in children.

Background: Most children and youth develop mild or asymptomatic disease during severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. However, a very small number of patients suffer severe Coronavirus induced disease 2019 (COVID-19). The reasons underlying these different outcomes remain unknown.

Blood neutrophils from children with COVID-19 exhibit both inflammatory and anti-inflammatory markers.

Background: Perhaps reflecting that children with COVID-19 rarely exhibit severe respiratory symptoms and often remain asymptomatic, little attention has been paid to explore the immune response in pediatric COVID-19. Here, we analyzed the phenotype and function of circulating neutrophils from children with COVID-19.

Methods: An observational study including 182 children with COVID-19, 21 children with multisystem inflammatory syndrome (MIS-C), and 40 healthy children was performed in Buenos Aires, Argentina.

Case report of Chagas disease reactivation: new diagnosis tool by direct microscopic observation of biopsy specimen and its preservation fluid.

Chagas Disease is caused by Trypanosoma cruzi. This infection is endemic in the Americas region. Neurological Chagas reactivation is diagnosed through the visualization of the parasite in the cerebrospinal fluid, blood, or tissue samples.

Endometriosis Presenting as Recurrent Haemorrhagic Ascites: A Case Report and Literature Review.

Endometriosis is a common condition that occurs in 6-10% of all reproductive age women. This number increases to approximately 40% in women with infertility and nearly 75% in women with complaints of chronic pelvic pain. Endometriosis is characterized by the presence of endometrial glands and stroma outside the uterine cavity.

Massive recurrent hemoperitoneum with encapsulating peritonitis: another enigmatic clinical feature of endometriosis.

Objective: To describe the clinical characteristics and laparoscopic findings of a very uncommon presentation of a patient with endometriosis.

Design: Video presentation of case report (Canadian Task Force classification III). (The institutional review board of the Hospital Naval Pedro Mallo, Buenos Aires, Argentina, has ruled that approval was not required for the publication of this case report.

[Stereotactic brain radiosurgery in the treatment of skull base tumors.].

Stereotactic radiosurgery has shown effectiveness in the multimodal treatment of skull base tumors, however it is suggested that in radiobiologically sensitive areas (eg. optic nerves and brainstem) the radiation dose should be reduced due to radiotoxic effects. To avoid the consequent therapeutic ineffectiveness, a recently implemented alternative is multisession radiosurgery (RCH).

Active compounds present inRosmarinus officinalis leaves andScutellaria baicalensis root evaluated as new therapeutic agents for endometriosis.

Research Question: Can carnosic acid, (CA) rosmarinic acid (RA) and wogonin (WG) inhibit the growth of cultured human endometrial stromal cells and endometriotic-like lesions induced in a BALB/c model of endometriosis?

Design: Primary stromal cell cultures were established from endometrial biopsies from women with endometriosis and controls. The human endometrial stromal cell line T-HESC was also used for in-vitro experiments. Endometriosis was surgically induced in BALB/c mice, which were randomly assigned to CA 2 mg/kg/day (n = 11); CA 20 mg/kg/day (n = 10); RA 1 mg/kg/day (n = 11); RA 3 mg/kg/day (n = 10); WG 20 mg/kg/day (n = 12); intraperitoneal vehicle control (n = 8) or oral vehicle control (n = 11).

['The man with the withered hand': iconography of the saturnine palsy?].

Introduction: The synoptic gospels tell about a man who cannot extend his hand, that appeared dried. The description is consistent with radial palsy. Christian artists depicted this gospel story producing a rich material, unexplored from the medical point of view.

[Evaluation of the VITEK 2 system (AST-YSO1 cards) for antifungal susceptibility testing against different Candida species].

The aim of this investigation was to evaluate the results of antifungal susceptibility for various Candida species using the Vitek 2 semi-automated system (AST-YSO1 cards, bioMérieux), and to compare them with those obtained by the CLSI (Clinical and Laboratory Standards Institute) broth microdilution reference method (Document M27-A3,2008). The essential agreement (EA) was > 90%, except for Candida glabrata against voriconazole (VCZ); and for Candida krusei against fluconazole (FCZ). The overall categorical agreement (CA) was > 90% when FCZ was evaluated and 89.

The case of a 52-year-old female patient with a history of critical aortic stenosis, hypothyroidism and splenectomy as treatment for her Hodgkin's lymphoma is herein presented. In April 2011, the patient was admitted to the cardiology service due to global heart failure, fever and poor response to diuretic and vasodilator therapy. A transesophageal echocardiogram showed images compatible with vegetations in the aortic, pulmonary, and mitral valves.

The natural history of a newly developed flexion contracture following primary total knee arthroplasty.

Purpose: We investigated the incidence, natural history, and functional consequences of a newly developed flexion contracture after total knee arthroplasty (TKA).

Methods: Forty patients with full knee extension preoperatively who developed a postoperative flexion contracture were match-paired 1:2 with 80 patients who had full extension. The incidence of a newly developed flexion contracture, ROM, and Knee Society scores (KSS) at six weeks, four months, and one year were analysed.

[Neisseria gonorrhoeae identification. Usefulness of the Vitek 2C NH card].

A total of 115 unique clinical isolates of Neisseria gonorrhoeae and 54 strains of other genera and species included in the database of the NH card were tested by the Vitek 2C System (bioMèrieux, Marcy L'Etoile, Francia). The gonoccocal isolates had been previously identified by conventional biochemical tests and by the latex agglutination test with monoclonal antibodies using the Phadebact Monoclonal GC Test (Bactus AB, Sweden). The NH card correctly identified 111 (96.

[Evaluation of direct susceptibility testing from blood culture bottles. Clinical usefulness].

A prospective observational study was conducted in two hospitals of Buenos Aires city (Argentina); 191 clinically significant monomicrobial gram-negative bloodstream infections were included in the study, which combined the Bact-Alert System Blood culture machine and the Vitek 2C System. Organism identification and susceptibility results directly from blood culture bottles were compared with those obtained from cards inoculated with a standardized bacterial suspension obtained following subculture on agar. By comparing the results obtained from pure cultures with those by the Vitek 2C System as reference method, the agreement between the reference method and the direct identification from positive blood cultures was 99 %.
