Preimplantation genetic diagnosis by fluorescence in situ hybridization: clinical possibilities and pitfalls.

2003

Preimplantation genetic diagnosis using the fluorescence in situ hybridization technique (FISH) is being used widely to prevent the transmission of sex-linked diseases, to screen for translocations, and for aneuploidy screenng in specific invitro fertilization (IVF) patient groups, along with FISH analysis of spematozoa in intertile men. In this study, we aim to critically analyze our clinical results in patients at risk of transmitting sex-linked diseases (n = 55), in carriers of translocations (n = 43), in women who have recurent miscarriage (two or more miscarriages) (n = 128), recurrent IVF failure (three or more failed IVF attempts) (n = 47), and patients of advanced maternal age (37 y…

Acute liver failure and HELLP syndrome: A clinical case and literature review.

2021

Summary Background HELLP syndrome is a pregnancy-related liver disease associated with increased maternal and foetal mortality. In rare cases, it can lead to the development of a subcapsular hepatic haematoma as well as its rupture. This rupture is life-threatening if not urgently treated. Method We describe a clinical case of HELLP syndrome involving a ruptured subcapsular liver haematoma and contextualise this with a literature overview. Clinical case A 39-year-old woman of 40 weeks’ gestation presented to her local Emergency Department with symptoms and serology classically associated with HELLP syndrome. However, she clinically deteriorated and developed a ruptured subcapsular haematoma…

Inducible nitric oxide synthase in skeletal muscle of patients with chronic heart failure

1998

Abstract Objectives. The expression and localization of inducible nitric oxide (NO) synthase (NOS II) was evaluated as a source of NO which has been shown to affect muscle contraction. Background. Advanced stages of chronic heart failure are associated with systemic activation of cytokines which have been shown to stimulate the expression of NOS II in various cell types, including myocytes. We hypothesized that systemic cytokine activation could lead to expression of NOS II in skeletal muscle of patients with chronic heart failure. Methods. Skeletal muscle specimens were obtained by percutaneous needle biopsy in six normal volunteers and eight patients with heart failure (New York Heart Ass…

Clinical significance of increased intraabdominal pressure in severe acute pancreatitis.

2002

The aim of the study was to assess whether increased intra-abdominal pressure affects the clinical course and reflects on the effectiveness of the conservative treatment in patients with severe acute pancreatitis. Data on 37 consecutive patients with severe acute pancreatitis that were collected prospectively included APACHE II score, daily measurement of the intra-abdominal pressure, and clinical routine. Group A consisted of 26 patients with intra-abdominal pressure < 25 cm/H 2 O during their treatment period, and group B consisted of 11 patients with intraabdominal pressure ≥ 25 cm/H 2 O. SIRS, MODS, complication rate and mortality were analysed. The age, APACHE II scores and hospital st…

Clinical comparison of extracorporeal piezoelectric lithotripsy (EPL) and intracorporeal electrohydraulic lithotripsy (EHL) in difficult bile duct st…

1995

Today, nearly 90% of common bile duct stones are extracted endoscopically. Problems are encountered if there are large stones or a duct stenosis. Extracorporeal piezoelectric lithotripsy (EPL) as well as intracorporeal electrohydraulic lithotripsy (EHL) serve as an alternative to surgical intervention for those few patients in whom endoscopic measures have failed. A total of 35 patients with common bile duct stones in whom conventional endoscopic treatment had failed were selected on the condition that stone visualization through ultrasound was possible and that the papilla was within easy reach of the endoscope. Patients fulfilling the inclusion criteria were randomly treated either by EPL…

Duration of HCV infection as a predictor of nonresponse to interferon

1996

Duration of hepatitis C virus (HCV) infection is a key feature in determining responsiveness to interferon (IFN). Studies assessing its value as a predictive factor in chronic HCV infection show that a long duration of infection reduces the likelihood of a sustained response to IFN (defined as ALT normalization and clearance of serum HCV-RNA). The effect of HCV infection duration is independent of the presence of cirrhosis and level of HCV viremia. Meta-analysis of IFN trials in acute HCV infection shows an obvious effect of the drug on long-term ALT normalization and HCV-RNA clearance. Treatment of HCV infection during the acute or early chronic phase could therefore maximize therapeutic e…

Assessment of the Tricuspid Valve Morphology by Transthoracic Real-Time-3D-Echocardiography

2005

Aim: To demonstrate the feasibility of transthoracic three-dimensional real-time echocardiography (3D-TTE) supplemental to routine assessments of the tricuspid valve and to analyze interrater agreement. Methods: Twenty healthy subjects and 74 patients with right ventricular failure were examined with conventional 2D and additionally 3D-TTE (SONOS 7500, Philips, Netherlands). The 3D exams were performed and recorded by one of two raters. The recordings were evaluated offline and independently by both raters for visualization of morphological and functional features of the tricuspid valve according to a subjective 3-point scale. Statistical analyses were performed for interrater agreement and…

Children born after autotransplantation of cryopreserved ovarian tissue. a review of 13 live births.

2011

Abstract Introduction. Premature ovarian failure (POF) can occur naturally at an early age or be due to iatrogenic agents. Indeed, ovaries are very sensitive to cytotoxic treatment, especially to radiation and alkylating agents. Methods. Several options are currently available to preserve fertility in cancer patients and allow them to conceive when they have overcome their disease: embryo cryopreservation, oocyte cryopreservation, and ovarian tissue cryopreservation. Cryopreservation of ovarian tissue is the only option available for pre-pubertal girls and women who cannot delay the start of chemotherapy. Findings. Since the first live birth after autotransplantation of cryopreserved ovaria…

Factors Affecting Early Mortality and 1-Year Outcomes in Young Women With ST-Segment-Elevation Myocardial Infarction Aged Less Than or Equal to 45 Ye…

2018

Given that up to 2% of patients with myocardial infarction (MI) are young women, the purpose of this study was to evaluate factors affecting outcomes in young women with ST-segment-elevation myocardial infarction (STEMI) aged less than or equal to 45 years. We evaluated 796 women with STEMI aged less than or equal to 45 years between 2007 and 2014, and mortality was 4.0%. Death occurred more often in women with prehospital sudden cardiac arrest, and severe symptoms of heart failure; less commonly, the women were subjected to percutaneous coronary intervention (PCI), with a higher rate of incomplete revascularization. Beta blockers (BB) and angiotensin converting enzyme inhibitors were frequ…
