Persistencia de residuos de disparo en puños de prendas de vestir
2013
La detección de partículas de residuos de disparo (RDD) en las ropas de un sospechoso es una evidencia muy importante en los casos judiciales para determinar si la persona disparó o no un arma de fuego. Sin embargo, debido a simples roces con otras superficies, las partículas asociadas al disparo se pierden por la actividad física de una persona. En este estudio se analizó la permanencia de los RDD retenidos sobre puños de prendas de vestir, luego de disparar una pistola calibre 9mm. Valiéndose de la técnica de Microscopía Electrónica de Barrido (SEM) combinada con Espectrometría de Energía Dispersiva (EDS) se caracterizó la morfología, composición y densidad de los RDD recolectados, tenien…
Understanding the SO 2 degassing budget of Mt Etna’s paroxysms: First clues from the december 2015 sequence
2019
The persistent open-vent activity of basaltic volcanoes is periodically interrupted by spectacular but hazardous paroxysmal explosions. The rapid transition from quiescence to explosive eruption poses a significant challenge for volcanic hazard assessment and mitigation, and improving our understanding of the processes that trigger these paroxysmal events is critical. Although magmatic gas is unquestionably the driver, direct measurements of a paroxysm’s gas flux budget have remained challenging, to date. A particularly violent paroxysmal sequence took place on Etna on December 2015, intermittently involving all summit craters, especially the Voragine (VOR) that had previously displayed no…
Shallow system rejuvenation and magma discharge trends at Piton de la Fournaise volcano (La Réunion Island)
2017
International audience; Basaltic magma chambers are often characterized by emptying and refilling cycles that influence their evolution in space and time, and the associated eruptive activity. During April 2007, the largest historical eruption of Piton de la Fournaise (Île de La Réunion, France) drained the shallow plumbing system (>240×106 m3>240×106 m3) and resulted in collapse of the 1-km-wide summit crater. Following these major events, Piton de la Fournaise entered a seven-year long period of near-continuous deflation interrupted, in June 2014, by a new phase of significant inflation. By integrating multiple datasets (lava discharge rates, deformation, seismicity, gas flux, gas composi…
Review of the genusiLanchnophorus/i(Hemiptera: Heteroptera: Rhyparochromidae) with description of three new species and other nomenclatural changes.
2017
The generic name Lanchnophorus Reuter, 1887, deemed for a long time to be unavailable as incorrect original spelling of Lachnophorus (in fact Lachnophorus Distant, 1903 is an unjustified emendation of the former), is restored as a valid name of the genus. Lachnesthus Bergroth, 1915, syn. nov. (new name for the preoccupied Lachnophorus Distant, 1903) is considered junior synonym of Lanchnophorus. The following nomenclatural changes are proposed: Lanchnophorus flavus (Scudder, 1971) comb. nov. = Lachnesthus chinai Scudder, nomen nudum; Lanchnophorus guttulatus Reuter, 1887, comb. restit. = Lachnophorus albidomaculatus Distant, 1913, syn. nov. = Lachnesthus rodriguezensis China, 1925, syn. nov…
Evaluation of serum CA 125 levels in patients with pelvic pain related to endometriosis.
2007
The aim of the study was to investigate the clinical value of the serum CA 125 level for diagnosing and determining the severity of endometriosis and pelvic pain associated with endometriosis. Eighty-six women who underwent operative laparoscopy were enrolled. Sixty-nine women with endometriosis and 17 without endometriosis participated in this study. In all of the patients, endometriosis was diagnosed and classified into stages according to the Revised American Fertility Society (R-AFS) classification. The mean serum CA 125 levels were determined in each patient. We also investigated the relationship between serum CA 125 concentration and the intensity of dysmenorrhea and dyspareunia in t…
Pleomorphic Adenoma and Adenoid-Cystic Carcinoma of the Salivary Glands: Comparative Immunohistochemical Patterns
1987
A series of 20 cases of pleomorphic adenoma and 19 cases of adenoid-cystic carcinoma of the salivary glands, and one case in the mammary location, were investigated regarding immunohistochemical reactivity for Tissue Polypeptid Antigen (TPA), Pre-Keratins, Vimentin, S-100 Protein, and their arrangement pattern of fibronectin. As a whole, the results support the hypothesis of morpho-structural and mainly, onto-histogenetic similarities between these tumours, but they also underline the need for great care in outlining their morpho-functional features, in relation to their different prognoses.
Adjuvant Radiotherapy After Minimally Invasive Surgery in Patients With Stage IA1-IIA1 Cervical Cancer
2021
To estimate whether adjuvant radiotherapy is necessary for patients with stage IA1-IIA1 cervical cancer after laparoscopic hysterectomy, 221 patients were retrospectively analyzed. Sixty-two of them were treated with laparoscopic hysterectomy and adjuvant radiotherapy (group A), 115 underwent open surgery (group B) and 44 received laparoscopic hysterectomy alone (group C). Results showed that the 3-year local recurrence-free survival (LRFS) rates of group A, B and C were 98.4%, 97.4% and 86.4%, respectively. The LRFS rates of group A and B surpassed C (A vs. B, p=0.634; A vs. C, p=0.011; B vs. C, p=0.006). The inter-group differences of 3-year overall survival (OS) and distant metastasis fr…
Paroxysmal nocturnal haemoglobinuria: When delay in diagnosis and long therapy occurs
2017
Paroxysmal nocturnal hemoglobinuria (PNH) is a rare clonal disorder characterized by hemolytic anemia, bone marrow failure and thrombosis, caused by a somaticmutation in PIG-A gene that results in theabsence of CD55 and CD59, two important complement regulatory proteins. In thispaper, a case of PNH is retrospectively examined looking for clinical and laboratory features, and the entire course of the disease from the onset of the symptoms isdescribed, together with an adequate follow-up over a 7-years treatment period. Inthis case, the not specificity and the limited clinical relevance of the symptoms led to adelay in diagnosis. After thrombosis, Eculizumab therapy has been shown to be effec…
Unfused Liver Segments: a Case Report of an Unknown Phenotype of the Conradi-Hünermann-Happle Syndrome
2016
Background: Since its description in 1957, Couinaud`s classification of the segmental organization of the liver has remained valid. However, recent investigations by 3-dimensional computed tomography suggest a significant variability of the vascular anatomy and segment volume. Here, we report a surprise finding during the laparoscopic cholecystectomy of a patient with Conradi-Hünermann-Happle syndrome, in whom the liver segments were not fused.
 Case report: Laparoscopic cholecystectomy was performed because of recurrent biliary pancreatitis in a 47 year-old male patient, who had been diagnosed with Conradi-Hünermann-Happle syndrome. Upon direct view, the liver parenchyma appeared norm…
Benign nocturnal alternating hemiplegia of childhood
2018
Objective: To describe the clinical spectrum of benign nocturnal alternating hemiplegia of childhood (BNAHC) including long-term follow-up data of previously published cases and to propose an underlying genetic cause of this disorder. Methods: We studied the medical data of two novel patients, reviewed the literature on BNAHC, and gathered information of the most recent follow-up of published cases regarding the course of episodes, further development, attempted drugs, ancillary investigations, and sequelae. Results: All patients, i.e. two novel cases and twelve patients identified in the literature (13 boys, 1 girl, age at onset four months to three years), experienced episodes of hemipleg…
