Abdominal Tumor in a 14-Year-Old Adolescent: Imperforate Hymen, Resulting in Hematocolpos—A Case Report and Review of the Literature
2014
Background. Abdominal masses in female adolescents are uncommon. A rare cause of this condition is hematocolpos due to imperforate hymen.Case. We present a case of an unusually massive asymptomatic abdominal bulk in a 14-year-old female patient, who sought for medical advice after unusual abdominal pain lasting for few weeks. The patient was otherwise asymptomatic, apart from an unusual dramatic expansion of her abdominal wall during the last month. We describe the surgical management and the follow-up of the patient.Summary and Conclusion. Clinicians should keep in mind that an imperforate hymen can cause abdominal growth due to hematocolpos and include it in the differential diagnosis of …
Prenatal Brain Damage in Preeclamptic Animal Model Induced by Gestational Nitric Oxide Synthase Inhibition
2010
Cerebral palsy is a major neonatal handicap with unknown aetiology. There is evidence that prenatal brain injury is the leading cause of CP. Severe placental pathology accounts for a high percentage of cases. Several factors predispose to prenatal brain damage but when and how they act is unclear. The aim of this paper was to determine if hypoxia during pregnancy leads to damage in fetal brain and to evaluate the localization of this injury. An animal model of chronic hypoxia produced by chronic administration of a nitric oxide synthase inhibitor (L-NAME) was used to evaluate apoptotic activity in fetal brains and to localize the most sensitive areas. L-NAME reproduces a preeclamptic-like c…

Conceptual changes in lease accounting: Regulatory and academic challenges
2019
El objetivo principal de este trabajo es demostrar que el posicionamiento de los emisores de normas contables y el de los grupos de presión es coherente con la Teoría de la Ideología de la regulación y la Teoría Positiva de la Contabilidad de los efectos económicos, respectivamente. Sin embargo, contrariamente a la literatura previa de lobbying, argumentamos que en un contexto internacional y tras a˜nos de experiencia con las Normas Internacionales de Información Financiera (NIIF), todos los agentes, y no solo los emisores de las normas, utilizan aspectos conceptuales y técnicos, ya que los grupos de interés, fundamentalmente los preparadores, prevén hacer más efectiva su actividad de lobby…
Placenta Accreta Spectrum Disorder in a Patient with Six Previous Caesarean Deliveries: Step by Step Management
2021
The definition placenta accreta spectrum disorders (PAS) introduced by FIGO (International Federation of Gynaecology and Obstetrics) indicates an abnormal, pathological adherence or invasion of the placenta. The growing worldwide incidence of this pathological entity, and the possible serious correlated surgical risks, has caused a significant increase in attention among the scientific community. Previous caesarean delivery and presence of placenta previa are the main risk factors for the onset of PAS. Here, we present the intriguing case of a 39-year-old woman, at the 33rd week of gestation, with six previous caesarean sections and with a diagnosis of placenta previa accreta. At our referr…
Tips and tricks in office hysteroscopy
2015
Abstract Office hysteroscopy is a minimally invasive procedure that has been shown to be highly accurate in diagnosing abnormalities of the endometrial cavity and the endocervical canal. It allows the direct visualizing of uterine pathology without the need for general anesthesia and the use of an operating room, generating cost savings and greater compliance among patients. The advent of small-diameter hysteroscopes, the use of saline solution as a distension media, as well as the vaginoscopic technique have widely contributed to the diffusion of this technique worldwide, and currently it can be considered the gold standard for the examination of the uterine cavity. The improved technology…
Maternal risk factors of urinary incontinence during pregnancy and postpartum: A prospective cohort study
2021
Highlights • Urinary incontinence after delivery affects every fifth woman. • Urinary incontinence before pregnancy is a risk factor of postpartum incontinence. • Primiparous women are at a greater risk of urinary incontinence after birth.
Growth factors and cell kinetics: a mathematical model applied to Il-3 deprivation on leukemic cell lines.
1992
We assume the existence of a specific G1 protein which is an initiator of DNA replication. This initiator is supposed to be synthesized according to Michaelis-Menten kinetics. In order to start DNA replication, it is assumed that this G1 specific protein must be produced in a required amount. Intra-cellular growth inhibitors and extra-cellular growth factors control the production of the initiator. This model allows to calculate the average G1 phase time as a function of the various chemical concentrations of nutrients, enzymes, growth inhibitors and growth factors. This model is compared to cell kinetics experiments on a leukemic cell line responding to Interleukin 3 deprivation. The curve…
“Throwing into the Whirlwind Vortex”: Unaccounted Memoirs about Blok by S. Korenev
2021
The article examines certain plots of the “Blok theme” in the 1920s Riga periodicals, which had not previously attracted the attention of researchers. The Russian press of independent Latvia (1919 –1940) has preserved many tens, if not hundreds, of articles, correspondences, documents, poetic texts dedicated to A.A. Blok’s personality and works. Among them are memoirs of people who were familiar with the poet, met with him, listened to his speeches. However, most of these scattered memoirs remain forgotten and are not taken into account in the Blok studies. The author recalls the texts of V.V. Tretyakov, A.M. Perfiliev and republishes from the Riga newspaper “Slovo” a memorial article about…
