Myelodysplastic syndrome (MDS) predominantly occurs in aging people. Over the past decades, the cellular and molecular pathologies of MDS cells have been intensively investigated. However, how the bone marrow stromal niches are altered during MDS development remains elusive. In this study, we attempted to isolate and characterize mesenchymal stromal cells (MSCs) from 30 MDS patients. We observed that only 9/30 bone marrow aspirations from MDS patients successfully formed a monolayer in vitro, while 17/17 bone marrow aspirations from normal donors (median age 45 years, range: 22-73 years) succeeded in this process...

An 80-year-old woman initially presented with an episode of pleuritic chest pain 10 days after implantation of a dual chamber permanent pacemaker. She returned to hospital a day later with vomiting and fever. She was found to have new atrial fibrillation in addition to right-sided weakness and dysarthria. An infarct in the left anterior inferior cerebellar artery territory was later confirmed on CT. She continued to have recurrent febrile episodes associated with vomiting and dyspnoea. Extensive investigations for infection were negative, and her symptoms were initially attributed to aspiration pneumonia...

Few cases have been reported in which the aspiration of a single follicle led to the recovery of two conjoined oocytes surrounded by a single zona pellucida. This report describes a successful embryo transfer with subsequent live birth derived from conjoined oocytes, and a later pair of conjoined oocytes in the same patient. After oocyte retrieval from a patient with polycystic ovary syndrome, two pairs of conjoined oocytes were collected. One oocyte was fertilized using in vitro fertilization (IVF) and developed to the blastocyst stage...

We present a very rare case of right-sided isolated pleural effusion in a patient with severe endometriosis who, in relation to in vitro fertilization (IVF), developed ovarian hyperstimulation syndrome (OHSS). Earlier laparotomy showed grade IV endometriosis including endometriotic implants of the diaphragm. The patient had no known risk factors for OHSS and only a moderate number of oocytes aspirated. She received, however, repeated hCG injections for luteal support. The patient did not achieve pregnancy but was hospitalized due to pain in the right side of the chest and dyspnoea...

Wunderlich Syndrome (WS) is an uncommon condition where acute onset of spontaneous bleeding occurs into the subcapsular and perirenal spaces. It can prove fatal if not recognized and treated aggressively at the appropriate time. A 32-year-old male diagnosed elsewhere as acute renal failure presented with tender left loin mass, fever and hypovolemic shock with serum creatinine 8.4 mg/dl. He was started on higher antibiotics and initiated on haemodialysis. Ultrasonogram (USG), Non-Contrast Computed Tomography (NCCT) and Magnetic Resonance Imaging (MRI) showed bilateral perirenal subcapsular haematomas - right 3...

Acute respiratory distress syndrome (ARDS) is a pulmonary disorder associated with alterations to the pulmonary surfactant system. Recent studies showed that supra-physiological levels of cholesterol in surfactant contribute to impaired function. Since cholesterol is incorporated into surfactant within the alveolar type II cells which derives its cholesterol from serum, it was hypothesized that serum hypercholesterolemia would predispose the host to the development of lung injury due to alterations of cholesterol content in the surfactant system...

Recent studies have shown an association between alterations in laryngopharyngeal mechanosensitivity (LPMS) and dysphagia, obstructive sleep apnea, and chronic cough hypersensitivity syndrome. A previous reliability study of a new laryngopharyngeal endoscopic esthesiometer and rangefinder (LPEER) showed high intra- and inter-rater reliability; however, its accuracy has not been tested. We performed an accuracy study of the LPEER in a prospectively and consecutively recruited cohort of 118 patients at two tertiary care university hospitals...

The aims of the present study were to determine the effect of follicular fluid obtained from the ovulatory follicle of repeat breeder heifers on in vitro oocyte maturation (Experiment 1), fertilization (Experiment 2) and production of bovine embryos (Experiment 3). Holstein virgin heifers (VH, n = 5) with normal fertility or repeat breeder syndrome (RBH, n = 5) were used in the present study. Follicular fluid of VH and RBH was aspirated from ovulatory follicles and used as maturation medium. Bovine oocytes were aspirated from follicles of slaughterhouse ovaries and randomly allocated in three groups; in Group 1, oocytes cultured in TCM-199 supplemented with 10% heat-treated fetal calf serum and hormones (5 IU/mL hCG plus 0...

Severe fever with thrombocytopenia syndrome is an emerging life-threatening infectious disease identified in 2009. Given high case-fatality rate among patients with severe fever with thrombocytopenia syndrome, identification of the risk factors at acute phase associated with fatality is crucial for treatment. Therefore, we aimed to meta-analytically evaluate risk factors of fatal clinical outcome of severe fever with thrombocytopenia syndrome. 238 fatal cases and 873 non-fatal cases from 12 studies were included in this meta-analysis...

Hydrocarbon aspiration (HA) can cause significant lung disease by inducing an inflammatory response, hemorrhagic exudative alveolitis, and loss of surfactant function. The most serious side effect of HA is aspiration pneumonia. Pneumothorax, pneumatocele, acute respiratory distress syndrome (ARDS), pulmonary abscess, bronchopleural fistula, bilateral hemorrhagic pleural effusion and pyopneumothorax were previously reported. Hereby we report a patient hospitalized due to aspiration pneumonia who developed pleurisy and pneumothorax after drinking paint thinner...

A previously healthy 5-week-old female was admitted for sepsis secondary to methicillin-resistant Staphylococcus aureus (MRSA) bacteremia. After several days of hospitalization, she experienced acute decompensation in mental status despite having received targeted antibiotic therapy. Imaging revealed left peritonsillar/parapharyngeal space abscess, left venous thrombophlebitis of the internal jugular vein, and septic emboli of the lungs and brain consistent with Lemierre syndrome. Bedside needle aspiration of the parapharyngeal abscess confirmed MRSA involvement...

Talaromyces marneffei is a dimorphic fungus endemic mainly in southeast and south Asia. It causes severe mycosis, usually in immunocompromised individuals, such as those with human immunodeficiency virus (HIV) infection. Concomitant infection with T. marneffei and other opportunistic pathogens is plausible because the majority of T. marneffei infections occur in patients with advanced HIV infection. Nonetheless, coinfection in the same site has rarely been reported, and poses a considerable diagnostic and therapeutic challenge...

BACKGROUND: Allo-immune mediated lung syndromes (allo-LS) are life-threatening complications after hematopoietic cell transplantation (HCT). Respiratory virus (RV) has been suggested to play a role in the pathogenesis. OBJECTIVE: We studied the relation between RV-DNA/RNA detection in upper/lower airway before HCT and the occurrence of allo-LS. METHODS: We retrospectively analyzed all HCT recipients between 2004 and 2014, in whom Real-Time PCR for RV was done from Nasal-Pharyngeal-Aspirates (NPA) and Broncho-Alveolar- Lavage (BAL) before HCT...

We provide the first complete biophysical study of surfactant by captive bubble surfactometry from a neonate with meconium-stained amniotic fluid under controlled whole body hypothermia. Surfactant function improves after 48 hours of hypothermia, as surfactant cholesterol decreases. These findings partially explain positive effect of hypothermia on respiratory outcomes during meconium aspiration syndrome. A larger study including several neonates with or without lung disease is being conducted to better define the effect of hypothermia on surfactant function...

BACKGROUND: Volume-controlled ventilation modes have been shown to reduce duration of mechanical ventilation, incidence of chronic lung disease, failure of primary mode of ventilation, hypocarbia, severe intraventricular hemorrhage, pneumothorax, and periventricular leukomalacia in preterm infants when compared with pressure limited ventilation modes. Volume-guarantee (VG) ventilation is the most commonly used mode for volume-controlled ventilation. Assist control, pressure-support ventilation (PSV), and synchronized intermittent mandatory ventilation (SIMV) can be combined with VG; however, there is a lack of knowledge on the superiority of each regarding clinical outcomes...

Triathletes need to effectively fuel during training and racing to maximize their potential for success. While most research on fueling has focused on elite male triathletes, triathlon participation encompasses a broader demographic of racers ranging from those with aspirations of winning to those whose goals are completion. Carbohydrate is the primary macronutrient for fueling endurance activities. Athletes can usually tolerate 60 to 90 mg·h in the form of multiple different carbohydrate sources. Athletes should drink as thirst dictates and consider sodium replacement of sweat loss especially in individuals with a history of exercise-associated muscle cramps...
