Mucormycosis infection associated with global COVID-19 pandemic - an institutional histopathological study

2023

Coronavirus disease 2019 (COVID-19) in the recent times have instilled signs of immunosuppression globally which has further precipitated increasing range of opportunistic infections. Mucormycosis is a distressing opportunistic fungal infection with a high incidence and is the third commonest acute invasive infection following candidiasis and aspergillosis. The aim of the present observational study is to delineate the enigmatic histopathological profile between mucormycosis cases seen prior to pandemic (PPM) and pandemic associated mucormycosis (PAM). Tissue archives of 105 histopathologically diagnosed cases of mucormycosis were included and analysed for demographical details and histopat…

New Technique in Tendon Sport Recovery. Percutaneous Electrolysis Intratissue (EPI®)

2013

Based on the literature and clinical experience we know that the technique of percutaneous electrolysis intratissue (EPI ® ) has positive effects on the recovery of human tendinopathies. The application of the technique, together with the completion of eccentric exercise, give benefits leading to anatomical and functional recovery in the tendon that can be appreciated by ultrasound using the scale of "Victorian Institute of Sport Assessment-patellar tendon" (VISA-P). Due to clinical knowledge, damage to tendon is accompanied by increase in oxidative stress, cell death and inflammation at the damaged area. The EPI ® technique produced a galvanic current inside the tendon, with an acupuncture…

Stability of topotecan infusion solutions in polyvinylchloride bags and elastomeric portable infusion devices

1999

Purpose. The purpose of this study was to determine the physicochemical stability of topotecan after reconstitution and after further dilution in two commonly used infusion fluids (0.9% sodium chloride, 5% dextrose) in both polyvinylchloride (PVC) bags and elastomeric portable infusion devices. Methods. Each vial of topotecan (Hycamtin®) was reconstituted with sterile water for injection, yielding a nominal concentration of 1 mg/mL. Topotecan infusion solutions were aseptically prepared by further dilution of reconstituted topotecan solutions with either 0.9% sodium chloride or 5% dextrose in both PVC bags and portable elastomeric infusion devices, in amounts yielding topotecan concentrati…

Influence of nerve growth factor in endometriosis-associated symptoms

2011

To investigate the role of the nerve growth factor (NGF) in the development of dysmenorrhea/pelvic pain in patients with endometriosis, we performed a prospective, clinical, blind study. Peritoneal fluids (PFs) were obtained from patients with histologically proven endometriosis. Patients with endometriosis were divided into 7 different groups depending on their preoperative pain score and symptomatology: patients with no pain, patients with minimal pain (dysmenorrhea, pelvic pain, or both), and patients with severe pain (dysmenorrhea, pelvic pain, or both) and were used for the neuronal growth assay with cultured chicken dorsal root ganglia (DRG) and for Western blot analyses. Dorsal root …

Intermittent hypobaric hypoxia applicability in myocardial infarction prevention and recovery.

2012

Abstract Intermittent hypobaric hypoxia (IHH) has been the focus of important research in cardioprotection, and it has been associated with several mechanisms. Intermittent hypobaric hypoxia inhibits prolyl hydroxylases (PHD) activity, increasing the stabilization of hypoxia-inducible factor-1 (HIF-1) and activating crucial adaptative genes. It has been hence suggested that IHH might be a simple intervention, which may offer a thoughtful benefits to patients with acute myocardial infarction and no complications. Nevertheless, several doubts exist as to whether IHH is a really safe technique, with little to no complications in post-myocardial infarction patients. Intermittent hypobaric hypox…

Novel Perspectives in the Detection of Oral and Nasal Oxidative Stress and Inflammation in Pediatric United Airway Diseases

2010

United airway disease (UAD) concept proposed that asthma and rhinitis are both different clinical manifestation of a single inflammatory process. The aim of this study is to assess in upper and lower airways the level of inflammation and oxidative stress and to investigate the relationship between biomarkers in persistent allergic rhinitis (PER) and in concomitant asthma with PER. By a crosssectional study we measured oral and nasal (FENO) and oral and nasal EBC 8-isoprostane, LTB4 and PGE2 in children with PER (n=14) and with PER and concomitant intermittent asthma (IA; n=25), mild persistent asthma (mA; n=28), moderate persistent asthma (MA; n=13) and in Healthy Controls (HCs; n=13). Oral…

Prognostic factors for non-asphyxia-related cardiac arrest patients undergoing extracorporeal rewarming - HELP Registry Study

2020

Objective: Extracorporeal rewarming is the treatment of choice for patients who had hypothermic cardiac arrest, allowing for best neurologic outcome. The authors’ goal was to identify factors associated with survival in nonasphyxia-related hypothermic cardiac arrest patients undergoing extracorporeal rewarming. Design: All 38 cardiac surgery departments in Poland were encouraged to report consecutive hypothermic cardiac arrest patients treated with extracorporeal life support. All variables collected were analyzed in order to compare survivor and nonsurvivor groups. The parameters available at the initiation of extracorporeal rewarming were considered as potential predictors of survival in …

Evoked local field potentials can explain temporal variation in blood oxygenation level-dependent responses in rat somatosensory cortex

2010

The aim of this study was to explain the temporal variations between subjects in the blood oxygenation level-dependent (BOLD) response. Somatosensory responses were elicited with the electrical forepaw stimulus at a frequency of 10 Hz in urethane-anesthetized rats, and functional magnetic resonance imaging (fMRI) with BOLD contrast and local field potential (LFP) measurements were performed simultaneously. BOLD fMRI activation was evaluated by two different models, one based on the stimulus paradigm (the block model) and the other on the simultaneously measured evoked LFP responses. In the initial analysis, the LFP model captured the BOLD activation in the primary somatosensory cortex in al…

Penetration of 2% cyclosporin eyedrops into human aqueous humour.

1989

The penetration into the eye and the systemic absorption of 2% cyclosporin eye drops were determined by polarisation immunofluorescent assay of cyclosporin in the aqueous humour and plasma of 30 patients at the time of cataract surgery. The results were then compared with the corresponding results after oral administration at a dosage of 5 mg/kg/day to three further patients. The maximum intraocular concentration (24 (SD 9) mg/l) was achieved four hours after topical administration. This level was slightly less than that found in aqueous humour (28 (SD 10) mg/l) 12 hours after systemic administration of the drug at a dosage of 5 mg/kg/day. Both these levels are below the minimum therapeutic…
