This case reports describes a 39-year-old female with a history of surgically repaired hypoplastic left heart syndrome who presented with a left peripherally inserted central catheter (PICC) with associated large volume subclavian and brachiocephalic vein thrombus. Due to the presence of a right-to-left shunt via a fenestrated Fontan, there was clinical concern for a paradoxical embolism during removal of the PICC. The AngioVac aspiration system was successfully utilized to aspirate thromboemboli from the level of the proximal Glenn shunt during manipulation and removal of the PICC. This is the first reported case to demonstrate the safe and effective use of the AngioVac aspiration system for protection of paradoxical emboli through a cardiac right-to-left shunt during a procedure at high risk for thromboembolism.

Acute Intraoperative Pulmonary Aspiration

Nason, Katie S.

2015-01-01

Synopsis Acute intraoperative aspiration is a potentially fatal complication with significant associated morbidity. Patients undergoing thoracic surgery are at increased risk for anesthesia-related aspiration, largely due to the predisposing conditions associated with this complication. Awareness of the risk factors, predisposing conditions, maneuvers to decrease risk and immediate management options by both the thoracic surgeon and the anesthesia team is imperative to reducing risk and optimizing patient outcomes associated with acute intraoperative pulmonary aspiration. Based on the root-cause analyses that many of the aspiration events can be traced back to provider factors, having an experienced anesthesiologist present for high-risk cases is also critical.

A female patient, 17 years old with Poland's syndrome and myasthenia gravis was seen due to a bronchial infection and atelectasis. The respiratory pathology was treated by bronchial aspiration and respiratory support in the intensive care unit. The myasthenia gravis improved substantially after thymectomy. The association of Poland's syndrome and myasthenia is rare and it has not been reported previously; it may be a factor in the pulmonary pathology observed in this case.

Diagnostic bone marrow aspiration, biopsy, and culture are useful procedures in the evaluation of patients with suspected or proven acquired immunodeficiency syndrome (AIDS) who are febrile. In as many as one fourth of these patients, the information provided by the bone marrow examination may establish a diagnosis of a disseminated opportunistic infection when other studies are not informative. We have also discovered a previously unreported association between thrombocytopenia and the presence of bone marrow granulomas in our patients with AIDS and suggest that thrombocytopenia may be a clue to enable the clinician to predict a positive bone marrow result more accurately. The explanation for this apparent association remains to be elucidated.

Foreign body aspiration (FBA) is a preventable cause of mortality and morbidity in children. We conducted a chart review of children who presented to a university hospital due to FBA in the period 1999-2014. Children were either managed with bronchoscopy for removal of the foreign body or died due to FBA. A total of 103 children were seen due to FBA including 27 deaths. The majority of children were boys and were less than 3 years old. Most aspirated foreign bodies were food-related, mainly peanuts. The majority of children presented with acute choking incidents, a smaller number presented with recurrent chest infections, and few children's choking incidents were unwitnessed. X-ray had a high rate of false negatives and bronchoscopy was the gold standard technique for assessment and management. Aspiration of foreign bodies is a preventable, life-threatening condition that calls for increased parent education and awareness. Copyright © 2017 Elsevier B.V. All rights reserved.

The aim of this study was to investigate the effect of different doses of prednisolone in puppies experimentally induced with meconium aspiration syndrome (MAS). Meconium was collected from human babies in the first day of life and was released into the trachea of 11 newborn puppies to induce MAS. Puppies were treated with 2 mg/kg prednisolone (standard dose), 30 mg/kg prednisolone (megadose) or 0.9% saline, all administered intravenously. The study ended 20 h after meconium aspiration and the lungs were then scored for histopathology. Animals not treated with prednisolone deteriorated after 8 h while respiration rate, oxygenation, pH and partial pressure of carbon dioxide values were better in the prednisolone-treated groups. Histopathology scores were better in the treatment groups compared with the control group, with megadose giving the best result. At the end of the study, serum malondialdehyde levels were significantly higher in the megadose prednisolone group compared with the other two groups. In conclusion, we determined that prednisolone reduced physiological and histological changes in puppies with MAS and that a 30 mg/kg dose was more effective than 2 mg/kg.

Fine-needle aspiration of subcutaneous fat (FNAF) was performed in 24 patients, 12 with previously diagnosed amyloidosis presenting with proteinuria or nephrotic syndrome, and 12 presenting a nephrotic syndrome without amyloidosis on renal biopsy. FNAF was positive in 10 of 12 patients with amyloidosis (sensitivity: 83%) and negative in 12 of 12 patients with non-amyloid nephrotic syndrome (specificity: 100%). Considering a 2.5 to 10% prevalence of amyloidosis in adult patients with proteinuria or nephrotic syndrome, a positive FNAF is diagnostic of amyloidosis, and a negative FNAF rules out the diagnosis with a probability of 98 to 99%. FNAF is a simple and safe method which can be useful in patients who cannot undergo a renal biopsy.

Foreign body (FB) aspiration occurs mainly in children under 3 years of age and is one of the most frequent causes of accidental death under 12 months of age. The increased risk of FB aspiration in children is due to the different structure of the pharynx and the upper airways compared to adults. In addition, children have an immature swallowing mechanism and they most commonly aspirate food stuffs. FB aspiration is usually a sudden and dramatic event when the child feels that he is suffocating or choking. After the acute event, the clinical presentation widely ranges from severe respiratory distress to the most minimal symptoms. Bronchoscopy is the best diagnostic and therapeutic modality for FB inhalation. Prevention and rapid diagnosis can be lifesaving. In 2010, the American Academy of Pediatrics published a position paper on prevention of FB aspiration. The association calls for more proactive preventative measures to protect children from FB aspiration and to prevent mortality and morbidity. These include: 1. Raising awareness of parents and caregivers to supervise children and create a safe environment for them. 2. Promoting legislation and enforcing regulations that will prevent dangerous products being sold for children. 3. Changing the design of products, especially food products and toys, that will reduce the risks of choking. In this overview we will show the principles of diagnosis of FB aspiration and a flow chart including when flexible or rigid bronchoscopy is required.

Blastocystis is one of the most common gut parasites found in the intestinal tract of humans and animals. Its' association with IBS is controversial, possibly as a result of irregular shedding of parasites in stool and variation in stool detection. We aimed to screen for Blastocystis in colonic stool aspirate samples in adult patients with and without IBS undergoing colonoscopy for various indications and measure the interleukin levels (IL-8, IL-3 and IL-5). In addition to standard stool culture techniques, polymerase chain reaction (PCR) techniques were employed to detect and subtype Blastocystis. All the serum samples collected were subjected for ELISA studies to measure the interleukin levels (IL-8, IL-3 and IL-5). Among 109 (IBS n = 35 and non-IBS n = 74) adults, direct stool examination and culture of colonic aspirates were initially negative for Blastocystis. However, PCR analysis detected Blastocystis in 6 (17%) IBS and 4 (5.5%) non-IBS patients. In the six positive IBS patients by PCR method, subtype 3 was shown to be the most predominant (3/6: 50%) followed by subtype 4 (2/6; 33.3%) and subtype 5 (1/6; 16.6%). IL-8 levels were significantly elevated in the IBS Blasto group and IBS group (p<0.05) compared to non-IBS and non-IBS Blasto group. The level of IL-3 in were seen to be significantly higher in than IBS Blasto group and IBS group (p<0.05) compared to non-IBS. Meanwhile, the IL-5 levels were significantly higher in IBS Blasto group (p<0.05) compared to non-IBS and non-IBS Blasto group. This study implicates that detecting Blastosystis by PCR method using colonic aspirate samples during colonoscopy, suggests that this may be a better method for sample collection due to the parasite's irregular shedding in Blastocystis-infected stools. Patients with IBS infected with parasite showed an increase in the interleukin levels demonstrate that Blastocystis does have an effect in the immune system.

Background Foreign body aspiration refers to the inhalation of an object into the respiratory system and is a serious and potentially fatal event. A distinct group of patients has recently been recognized among Muslim nations. These patients include women who wear headscarves and place the safety pin in their mouth prior to securing the veils, leading to accidental foreign body aspiration. The aim of this study was to analyze the main presentation, diagnosis, treatment, and outcome of patients with scarf pin aspiration. Methods This prospective study involved patients with a history of scarf pin aspiration admitted to a single center during an 18-month period. Their main presentation, diagnosis, treatment, and outcome were analyzed. Results In total, 27 patients were included. The needle was extracted by flexible bronchoscopy in 12 (44.4%) patients, rigid bronchoscopy in 13 (48.1%), and thoracotomy in 2 (74%). One patient died during rigid bronchoscopy. All remaining 26 patients were satisfied with the postsurgical outcome at a mean follow-up of 1 week. Conclusions Scarf pin aspiration differs from other types of foreign body aspiration considering the specific population affected, and its management algorithm may thus differ from that of other foreign bodies. The left main bronchus is the most common site of pin impaction. Rigid bronchoscopy is the most commonly performed procedure for successful retrieval. PMID:28627978

2017-01-01

Post-obstructive pulmonary edema is thought to occur from hemodynamic changes secondary to forced inspiration against the closed airway due to acute or chronic airway obstruction. We report a case of a 13 month-old boy who developed pulmonary edema from aspirated foreign body, nuts. He underwent emergency bronchoscopy to confirm the clinical diagnosis of aspirated nuts in the trachea and nuts were removed endoscopically. His trachea was then intubated and he was mechanically ventilated with oxygen. He developed florid pulmonary edema early in the course with tracheal obstruction and during endoscopic removal of nuts. After removal of obstruction he was ventilated mechanically and pulmonary edema cleared rapidly. Aspirated nuts obstructing trachea can induce obstructive pulmonary edema. Early recognition of foreign body obstruction based on clinical history and its removal resolved pulmonary edema.

Among the etiologies of anemia in the newborn, those related to mitochondrial cytopathies are rare. Pearson syndrome is mostly diagnosed during infancy and characterized by refractory sideroblastic anemia with vacuolization of marrow progenitor cells and exocrine pancreatic dysfunction. We describe two diagnosed cases of Pearson syndrome in the early neonatal period caused by severe macrocytic aregenerative anemia. Bone marrow aspiration revealed sideroblastic anemia and vacuolization of erythroblastic precursors. The diagnosis was confirmed by genetic analysis revealing a deletion in the mitochondrial DNA. These two newborns received monthly transfusions. Five other newborns suffering from Pearson syndrome with various clinical symptoms were found in literature. Pearson syndrome, rarely diagnosed in newborns, should be suspected in the presence of macrocytic aregenerative anemia and requires a bone marrow aspirate followed by a genetic analysis from a blood sample.

Sewing machine oil ingestion is rare but is possible due to its availability at home. Chemically, it belongs to hydrocarbon family which is toxic if aspirated, owing to their physical properties such as high volatility and low viscosity. On the contrary, sewing machine lubricant has high viscosity and low volatility which makes it aspiration less likely. The main danger of hydrocarbon ingestion is chemical pneumonitis which may be as severe as acute respiratory distress syndrome (ARDS). We report a case of a 5-year-old girl with accidental ingestion of sewing machine lubricant oil, who subsequently developed ARDS refractory to mechanical ventilation. There was much improvement with airway pressure release ventilation mode of ventilation, but the child succumbed to death due to pulmonary hemorrhage.

Purpose Cayenne aspiration is an unusual type of foreign-body aspiration that is usually misdiagnosed. This article analyzes the clinical features of cayenne aspiration in the lower airway. Patients and methods Clinical data on eight adult patients with cayenne aspiration were retrospectively analyzed. Six were elderly patients. The data were collected from Peking University First Hospital and Anhui Chest Hospital between January 2010 and August 2014. Results The most common symptoms of cayenne aspiration were cough (eight cases, 100%) and sputum (five cases, 62.5%). Only one patient (12.5%) could supply the history of aspiration on his first visit to doctor and was diagnosed definitely without delay. The other seven cases were misdiagnosed as pneumonia and the time to accurate diagnosis was from 1 month to 6 months. The history of aspiration could be recalled after confirmed diagnosis for the other seven cases. The most common presentation shown by chest computed tomography (CT) was pneumonic opacity (eight cases, 100%). The existence of cayenne could not be detected by chest CT in any of the patients. All the patients were diagnosed definitively and managed successfully with flexible bronchoscopy. Cayenne was more often lodged in the right bronchus tree (seven cases, 87.5%), especially the right lower bronchus (four cases, 50%). The segment of cayenne was complete in five cases (62.5%) and scattered in three cases (37.5%). Conclusion The clinical features of cayenne aspiration are usually obscure and nonspecific which may lead to delay in diagnosis. Flexible bronchoscopy is safe and useful for early diagnosis and effective management. PMID:25473273

Postmortem endogenous ethanol production and diffusion from the lung due to aspiration of wood chip dust in the work place.

We report an autopsy case of postmortem ethanol diffusion into the cardiac blood after aspiration of wood chips, although antemortem ethanol consumption was not evident. A man in his twenties, who was loading a truck with small wood chips in a hot, humid storehouse, was accidentally buried in a heap of chips. At the time the body was discovered, 20 h after the accident, rectal temperature was 36°C. Autopsy showed the cause of death to be asphyxia due to obstruction of the airway by aspiration of wood chips. The ethanol and n-propanol levels were significantly higher in the lungs (left, 0.603 and 0.009 mg/g; right, 0.571 and 0.006 mg/g) than in other tissues. A significant difference in ethanol concentration was observed between the left cardiac blood (0.243 mg/g) and the right femoral blood (0.042 mg/g). Low levels of ethanol and n-propanol were detected in the stomach contents (0.105 and 0.001 mg/g, respectively). In order to determine whether aspiration of wood chips affects postmortem ethanol production in the lung, we measured the ethanol and n-propanol levels of homogenized rabbit lung tissue incubated with autoclaved or non-autoclaved wood chips. Levels of ethanol and n-propanol were significantly higher in the homogenates incubated with non-autoclaved chips for 24h. The results of this animal experiment suggested that the ethanol detected in the lung was produced by putrefactive bacteria within the wood chips. After death, the ethanol produced endogenously in the lung appears to have diffused and affected the ethanol concentration of the left cardiac blood. 2011 Elsevier Ireland Ltd. All rights reserved.

Refeeding syndrome (RS) is defined as the fluid, electrolyte, metabolic, and clinical disturbances that occur after nutrition of patients who have been undernourished or fasting for a prolonged period. This syndrome has been recognized for several decades but is most often overlooked and underdiagnosed by health professionals. The authors report a RS in a patient subjected to prolonged fasting after being kidnapped by a criminal gang. Refeeding resulted in severe hypophosphatemia, neurological impairments, and hematologic disorders. The patient died due to septic shock with multiple organ failure secondary to aspiration pneumonia. In this case, the failure to recognize RS was decisive in the fatal outcome. Professionals must be aware of this disease to prevent and treat it properly.

Little has been published about subclinical spinal canal stenosis due to C-1 hypoplasia in patients with Down syndrome. In this paper the authors performed a matched comparison study with cross-sectional survey to investigate occult spinal canal stenosis due to C-1 hypoplasia in children with Down syndrome. A total of 102 children with Down syndrome ranging in age from 10 to 15 years were matched according to age and physique with 176 normal children. In all participants, the anteroposterior (AP) diameter of C-1 and the atlas-dens interval (ADI) were measured on plain lateral x-ray images of the cervical spine. The cross-sectional area of the atlas was also measured from a cross-sectional computed tomography image of C-1. Eight children (6.7%) with Down syndrome developed atlantoaxial subluxation associated with myelopathy. The difference in the ADI between the patients and controls was not statistically significant. The average AP diameter of the atlas and the spinal canal area along the cross-section of the atlas were significantly smaller in children with Down syndrome than those in the control group. Atlantoaxial instability and occult spinal canal stenosis due to C-1 hypoplasia in patients with Down syndrome may significantly increase the risk of myelopathy.

Ultrafast cooling by total liquid ventilation (TLV) provides potent cardio- and neuroprotection after experimental cardiac arrest. However, this was evaluated in animals with no initial lung injury, whereas out-of-hospital cardiac arrest is frequently associated with early-onset pneumonia, which may lead to acute respiratory distress syndrome (ARDS). Here, our objective was to determine whether hypothermic TLV could be safe or even beneficial in an aspiration-associated ARDS animal model. ARDS was induced in anesthetized rabbits through a two-hits model including the intra-tracheal administration of a pH = 1 solution mimicking gastric content and subsequent gaseous non-protective ventilation during 90 min (tidal volume [Vt] = 10 ml/kg with positive end-expiration pressure [PEEP] = 0 cmH 2 O). After this initial period, animals either received lung protective gas ventilation (LPV; Vt = 8 ml/kg and PEEP = 5 cmH 2 O) under normothermic conditions, or hypothermic TLV (TLV; Vt = 8 ml/kg and end-expiratory volume = 15 ml/kg). Both strategies were applied for 120 min with a continuous monitoring of respiratory and cardiovascular parameters. Animals were then euthanized for pulmonary histological analyses. Eight rabbits were included in each group. Before randomization, all animals elicited ARDS with arterial oxygen partial pressure over inhaled oxygen fraction ratios (PaO 2 /FiO 2 ) below 100 mmHg, as well as decreased lung compliance. After randomization, body temperature rapidly decreased in TLV versus LPV group (32.6 ± 0.6 vs. 38.2 ± 0.4 °C after 15 min). Static lung compliance and gas exchanges were not significantly different in the TLV versus LPV group (PaO 2 /FiO 2  = 62 ± 4 vs. 52 ± 8 mmHg at the end of the procedure, respectively). Mean arterial pressure and arterial bicarbonates levels were significantly higher in TLV versus LPV. Histological analysis also showed significantly lower inflammation in

To investigate the feasibility of percutaneous epididymal sperm aspiration in dogs and whether it might provide a population of epididymal spermatozoa similar to the population that can be obtained by processing isolated epididymis caudae. Concentration and total sperm number, motility, morphology and acrosomal integrity of spermatozoa retrieved by percutaneous epididymal sperm aspiration, in vitro aspiration and mincing of the cauda of the epididymis were compared. Percutaneous epididymal sperm aspiration is a feasible procedure to retrieve a population of spermatozoa in dogs. Quality is similar to that of spermatozoa collected in vitro, although a wide variation amongst animals was observed. In case of ejaculation failure due to pathological conditions in dogs, the collection of spermatozoa from the cauda of the epididymis could be an option for providing gametes for assisted reproductive technologies. Percutaneous epididymal sperm aspiration can be used in dogs with compromised reproductive performance, in which orchiectomy cannot be performed for medical or owner reasons. Further studies aimed to investigate whether the percutaneous epididymal sperm aspiration technique might be feasible for repeated semen collection and to accurately evaluate side effects are required. © 2013 British Small Animal Veterinary Association.

A two-month-old infant died during bottle feeding in the supine position in the caregiver's absence. Scene investigations and autopsy examinations, including alpha-lactalbumin immunohistochemistry of the lungs, revealed the cause of death to be asphyxia due to aspiration of milk pooled in the naso-oral cavity, as a result of unsupervised supine feeding. This case emphasizes the need for an investigation into feeding positions and immunohistochemical examinations for the diagnosis of asphyxia due to milk aspiration.

Bardet-Biedl syndrome (BBS) is a rare autosomal recessive disorder with clinical and genetic heterogeneity. This syndrome was first described by Laurence and Moon in 1866 and additional cases were described by Bardet and Biedl between 1920 and 1922. The main features are obesity, polydactyly, pigmentary retinopathy, learning disabilities, various degrees of intellectual impairment, hypogonadism, and renal abnormalities. Bardet-Biedl syndrome is both phenotypically and genetically heterogeneous. Clinical diagnosis is based on the presence of 4 of the 5 cardinal features. The authors present a typical case of pigmentary retinopathy due to Bardet-Biedl syndrome and made a brief commentary about the disease's cardinal manifestations.

Herbal supplements are widely used during pregnancy, although there are insufficient data regarding their efficacy and safety. Some of them have been associated with hypertension, including licorice, which induces the so called mineralocorticoid-excess syndrome, a clinical picture resembling to pseudohyperaldosteronism. This action is mediated via inhibition of 11-hydroxysteroid dehydrogenase type 2 (11-HSD2), leading to impaired inactivation of cortisol to cortisone, accumulation of cortisol, and finally to excessive mineralocorticoid activity, especially in the distal and cumulative tubule of kidneys. This syndrome is characterized by hypertension and hypokalemia. Herein, we report a case of a 37-year-old pregnant woman, who was referred from obstetrics department to our department due to persistent hypertension and hypokalemia. She consumed a herbal supplement called "mumijo" during the last 6 months. After a thorough diagnostic work-up, the diagnosis of a "licorice-like syndrome" due to mumijo consumption was made. Potassium supplementation at the acute phase and discontinuation of mumijo were the treatment of choice. This is the first report of pseudohyperaldosteronism due to mumijo consumption in literature. Clinicians should be aware of this side effect and this agent should be included in those causing pseudohyperaldosteronism. Besides all, our case highlights the undeniable value of a detailed medical history.

Acute lung injury/acute respiratory distress syndrome (ALI/ARDS) is a manifestation of systemic inflammation in the lungs, but the factors that trigger inflammation in ALI/ARDS are unclear. We hypothesized that neutrophil extracellular traps (NETs) contribute to the pathogenesis of acid aspiration-induced ALI/ARDS. Analysis of bronchial aspirates from ARDS patients showed that NETs were significantly correlated with the degree of ARDS (r = -0.5846, p = 0.0359). NETs in bronchoalveolar lavage fluid of acid-aspiration mice were significantly higher (141.6 ± 23.08) at 3 h after injury than those in the sham group (1234 ± 101.9; p = 0.003, n = 5 per group). Exogenous NETs aggravated lung injury, while alvelestat and DNase markedly attenuated the intensity of ARDS. We investigated whether NETs are involved in the severity of gastric aspiration-induced ARDS. Then, a hydrochloric acid aspiration-induced ALI murine model was used to assess whether NETs are pathogenic and whether targeting NETs is protective. Exogenous NETs were administered to mice. Alvelestat can inhibit neutrophil elastase (NE), which serves an important role in NET formation, so we investigated whether alvelestat could protect against ALI in cell and mouse models. NETs may contribute to ALI/ARDS by promoting tissue damage and systemic inflammation. Targeting NETs by alvelestat may be a potential therapeutic strategy.

To describe a case of severe capsule contraction syndrome causing significant astigmatism due to intraocular lens (IOL) folding. Case report. Capsule fibrosis and contraction resulted in bending of the hydrophilic IOL along its long axis. Anterior Nd:YAG capsulotomy resolved the situation and restored the patient's visual acuity. Hydrophilic IOLs are more susceptible to capsule contraction due to the increased flexibility of highly hydrated materials. They should be avoided in patients at risk of capsule contraction to prevent ocular complications. [J Refract Surg. 2018;34(1):65-67.]. Copyright 2018, SLACK Incorporated.

Summary Background: Sjögren syndrome (SS) is an autoimmune-lymphoproliferative disorder characterized by mononuclear cell infiltration of exocrine glands. Clinically, Sjögren syndrome (SS) has a wide spectrum, varying from autoimmune exocrinopathy to systemic involvement. There have been few cases reporting that primary SS developed with distal renal tubular acidosis clinically. Case Report: Here, we present a case with primary Sjögren syndrome accompanied by hypopotassemic paralysis due to renal tubular acidosis. Severe hypopotassemia, hyperchloremic metabolic acidosis, alkaline urine and disorder in urinary acidification test were observed in the biochemical examination of the 16-year-old female patient, who had applied to our clinic for extreme loss of muscle force. After the examinations it was determined that the patient had developed Type 1 RTA (distal RTA) due to primary Sjögren syndrome. Potassium and alkaline replacement was made and an immediate total recovery was achieved. Conclusions: Hypopotassemic paralysis due to primary Sjögren syndrome is a rare but severe disorder that could lead to death if not detected early and cured appropriately. Thus, effective treatment should be immediately initiated in cases where severe hypopotassemia is accompanied by metabolic acidosis, and the cases should also be examined for extraglandular involvement of SS.

To determine the role of fine needle aspiration cytology in the diagnosis of extramedullary plasmacytoma. The study group consisted of 13 patients with palpable masses at various sites. The tumors were aspirated for cytologic study. The smears revealed groups of mature and immature plasma cells at various stages of maturation. Mature plasma cells showed an eccentric nucleus and abundant, deep, basophilic cytoplasm with a paranuclear halo. Plasmablasts (immature plasma cells) showed a prominent, eccentric nucleus with single, large nucleolus and abundant, deep, basophilic cytoplasm with no paranuclear halo. Binucleate and multinucleate forms were also seen quite often. The tumors were excised, and the histologic sections confirmed the cytologic diagnosis. All the patients received radiotherapy. One patient (18 years old) developed recurrence and died due to extensive infiltration into the maxilla and mandible. Two patients (57 and 62 years) developed multiple myeloma one to two years after the excision of tumors, and both died two to three months later. The remaining 10 patients were alive and well at this writing. The smears from all 13 patients were diagnosed as extramedullary plasmacytomas by fine needle aspiration cytology.

To investigate the effect of different degrees of pressure of sustained inflation (SI) in patients with acute respiratory distress syndrome (ARDS) after lung recruitment as the result of different negative pressure for sputum aspiration. A prospective single-blind randomized controlled trial was conducted. The factorial analysis of variance was adopted. 150 patients with ARDS admitted to the emergency intensive care unit (ICU) of Chongqing Three Gorges Central Hospital from January 2012 to December 2014 were enrolled, and they were randomly divided into S1, S2, S3 group, with 50 patients in each group, suction pressure varying from 150, 175, to 200 mmHg (1 mmHg=0.133 kPa) was respectively used in each group. Then the patients of each group were randomly subdivided into five subgroups of P0, P1, P2, P3, P4, with 10 patients in each group, and 0, 30, 35, 40, and 45 cmH2O (1 cmH2O=0.098 kPa) were used for control pulmonary inflation pressure, respectively. The respiratory mechanics and the hemodynamic parameters were recorded, and they were compared before and after the sputum aspiration as well as lung recruitment with sustained inflation. The lung recruitment volume (mL: 87.56±28.47 vs. 109.38±34.63, t=3.573, P=0.001) and lung static compliance [Cst (mL/cmH2O): 27.69±13.25 vs. 35.87±17.47, t=2.814, P=0.004] after sputum aspiration in the 150 patients were significantly lower than those before the sputum aspiration, and peak airway pressure [PIP (cmH2O): 24.16±8.28 vs. 18.63±6.67, t=2.957, P=0.005], airway plateau pressure [Pplat (cmH2O): 21.28±9.14 vs. 17.47±7.26, t=2.089, P=0.032], and mean airway pressure [Pm (cmH2O): 13.26±4.65 vs. 10.41±3.54, t=3.271, P=0.001] were significantly higher than those before the treatment. There were no significant differences in the lung recruitment volume, Cst, PIP, Pplat and Pm between groups with different negative pressure for sputum aspiration (F value was 0.809, 0.986, 1.121, 0.910, 1.043, and P value was 0.452, 0

Background and purpose. Transvaginal aspiration of ovarian cysts has been advocated as a viable alternative to surgery in patients who are high-risk surgical candidates. We describe a retrospective study evaluating the results of transvaginal aspirations of benign ovarian cysts in patients at increased surgical risk, focusing on long-term follow-up for recurrence of the cyst and/or development of malignancy. Methods. Twenty-four women with ovarian cysts underwent 34 transvaginal drainages between October 1998 and December 2004. All patients were referred following diagnosis of a persistent ovarian cyst with a benign appearance on ultrasound. All patients were unsuitable candidates for surgery (history ofmore » previous pelvic surgery, n = 21; high risk for anesthesia, n = 1; and unsuitable for laparoscopy due to obesity, n = 2). Patients with a history of pregnancy, acute abdominal symptoms, or previous gynecologic malignancy were excluded. A 20G x 20 cm Chiba needle was used for transvaginal aspiration using an endocavity probe (Acuson XP, Mountain View, CA, USA; Siemens Sololine, Erlangen, Germany) and intravenous sedoanalgesia. Cysts were aspirated to dryness. Results. Long-term follow-up of patients was performed and revealed a recurrence rate of 75%. Eighty-three percent of cysts on the left and 42% of those on the right recurred. Nine of 15 (60%) patients with recurrence required further intervention. Two of 9 underwent surgical intervention only, 4 of 9 had repeat transvaginal aspiration(s) performed, and 3 of 9 had a combination of both transvaginal aspiration and surgery. No patient developed ovarian malignancy. Conclusion. Transvaginal cyst aspiration has many advantages including short hospital stay, rapid recovery, excellent patient tolerance, and a low rate of procedure-related complications. Our study demonstrates that ovarian cyst recurrence following transvaginal drainage is a more significant problem than previously documented, especially if the

Aspiration can lead to serious pulmonary disease and occasionally death. Substances aspirated commonly include bacteria or gastric contents or both, but may be as unusual as diesel oil or a variety of foreign bodies. Pulmonary symptoms range from a subtle cough, wheezing, or hoarseness to severe dyspnea or asphyxiation. We discuss the mechanism of pulmonary disease caused by aspiration as well as the appropriate treatment.

Sequential voluntary cough and aspiration or aspiration risk in Parkinson's disease.

Disordered swallowing, or dysphagia, is almost always present to some degree in people with Parkinson's disease (PD), either causing aspiration or greatly increasing the risk for aspiration during swallowing. This likely contributes to aspiration pneumonia, a leading cause of death in this patient population. Effective airway protection is dependent upon multiple behaviors, including cough and swallowing. Single voluntary cough function is disordered in people with PD and dysphagia. However, the appropriate response to aspirate material is more than one cough, or sequential cough. The goal of this study was to examine voluntary sequential coughing in people with PD, with and without dysphagia. Forty adults diagnosed with idiopathic PD produced two trials of sequential voluntary cough. The cough airflows were obtained using pneumotachograph and facemask and subsequently digitized and recorded. All participants received a modified barium swallow study as part of their clinical care, and the worst penetration-aspiration score observed was used to determine whether the patient had dysphagia. There were significant differences in the compression phase duration, peak expiratory flow rates, and amount of air expired of the sequential cough produced by participants with and without dysphagia. The presence of dysphagia in people with PD is associated with disordered cough function. Sequential cough, which is important in removing aspirate material from large- and smaller-diameter airways, is also impaired in people with PD and dysphagia compared with those without dysphagia. There may be common neuroanatomical substrates for cough and swallowing impairment in PD leading to the co-occurrence of these dysfunctions.

Prader-Willi Syndrome: Obesity due to Genomic Imprinting

PubMed Central

Butler, Merlin G

2011-01-01

Prader-Willi syndrome (PWS) is a complex neurodevelopmental disorder due to errors in genomic imprinting with loss of imprinted genes that are paternally expressed from the chromosome 15q11-q13 region. Approximately 70% of individuals with PWS have a de novo deletion of the paternally derived 15q11-q13 region in which there are two subtypes (i.e., larger Type I or smaller Type II), maternal disomy 15 (both 15s from the mother) in about 25% of cases, and the remaining subjects have either defects in the imprinting center controlling the activity of imprinted genes or due to other chromosome 15 rearrangements. PWS is characterized by a particular facial appearance, infantile hypotonia, a poor suck and feeding difficulties, hypogonadism and hypogenitalism in both sexes, short stature and small hands and feet due to growth hormone deficiency, mild learning and behavioral problems (e.g., skin picking, temper tantrums) and hyperphagia leading to early childhood obesity. Obesity is a significant health problem, if uncontrolled. PWS is considered the most common known genetic cause of morbid obesity in children. The chromosome 15q11-q13 region contains approximately 100 genes and transcripts in which about 10 are imprinted and paternally expressed. This region can be divided into four groups: 1) a proximal non-imprinted region; 2) a PWS paternal-only expressed region containing protein-coding and non-coding genes; 3) an Angelman syndrome region containing maternally expressed genes and 4) a distal non-imprinted region. This review summarizes the current understanding of the genetic causes, the natural history and clinical presentation of individuals with PWS. PMID:22043168

Here we report an extremely rare case of Behçet syndrome (BS) that showed acute onset of Wallenberg syndrome and was treated successfully by corticosteroids. A 51-year-old woman with BS had a sudden onset of Wallenberg syndrome. Three days after the onset, she was transferred to our institute. In the magnetic resonance imaging (MRI) study on admission, T2-weighted and fluid-attenuated inversion recovery images showed a high intensity area in the left paramedian region of the medulla oblongata. Contrast-enhanced T1-weighted images showed enhancement in the vessel wall of the left vertebral artery. We diagnosed her as having Wallenberg syndrome due to the acute vertebral arteritis associated with BS. After initiation of high-dose steroid therapy, her symptoms gradually improved. Two months after admission, she was discharged from our institute with mild hemihypesthesia. We hypothesized that vertebral arteritis due to BS had caused hypoperfusion of the medullary perforators causing Wallenberg syndrome in our patient.

Imaging data from 30 patients with aspiration pneumonia were retrospectively analyzed, CT scaning was performed in 27 patients, which PMVR reconstruction was performed in 21 cases;3 exammed by X-ray with 2 used by esophagography. Opaque bodies were detected in trachea by CT scaning in 12 patients.7 patients in acute phase rapidly developed into acute respiratory distress syndrome(ARDS). CT signs of 30 patients with acute and chronic aspiration pneumonia included: centrilobular nodules were detected in 2 cases with acute phase, 4 cases with subacute phase and 4 cases with chronic phase; the imaging of ground glass opacity were detected in 9 cases with acute phase, 2 cases with subacute phase and 3 cases with chronic phase; the imaging of bronchiectasis was detected in 8 cases with chronic phase, which mucilage embolism was detected in 3 of 8 cases; the imaging of atelectasis was detected in 6 cases with chronic phase; the imaging of sheeted consolidation was detected in 5 cases with chronic phase, 8 case with acute phase; the imaging of interstitial fibrosis was detected in 3 cases with chronic phase. Lesions of inferior lobe of right lung were detected in 9 cases with chronic phase, 4 cases with subacute phase, 11 case with acute phase;lesions of inferior lobe of left lung were detected in 6 cases with chronic phase and 3 cases with subacute group, 11 case with acute phase. The imaging features of acute and chronic aspiration pneumonia overlap with GGO and centrilobular nodules in every group. While the imaging features of atelectasis, bronchiectasis or mucilage embolism are found in chronic phase. The chest CT scaning may accurately evaluate the dynamic change of aspiration pneumonia.

Associations between youths' reported relationships with their parents, beliefs about how success is attained, educational aspirations, and university completion were examined. Data come from the German Socioeconomic Panel. At age 17, youth (n = 3284) reported on their relationships with their parents, beliefs about success, and educational aspirations. University completion was assessed up to eight years later. At age 17, perceptions of parental warmth and interest in youths' academics were associated with beliefs that success is due to merit (positively) and that success is due to external factors or dominance over others (negatively). Beliefs that success is due to merit and external factors were associated with educational aspirations positively and negatively respectively. Educational aspirations positively predicted university completion up to eight years later. Relationships with parents had stronger associations with achievement when parents completed a university degree; beliefs about success had stronger associations with aspirations when parents did not.

Mirror syndrome is a rare complication of twin-twin transfusion syndrome (TTTS). Its clinical picture includes massive edema, oliguria, and hemodilution in the context of fetal hydrops. The occurrence of mirror syndrome after fetoscopic laser therapy for TTTS has been well documented, but resolution of mirror syndrome before delivery has not been reported in the literature. A 33-year-old woman was referred to our institution at 23(6)/7 weeks' gestation for TTTS, which had been treated with amnioreduction twice: at 21 and 22 gestational weeks, respectively. Mirror syndrome was diagnosed after fetoscopic laser therapy for TTTS at 24 weeks' gestation due to maternal manifestations of pulmonary edema, skin edema, anemia, low blood protein concentration and proteinuria accompanied by donor hydrops. The maternal respiratory symptoms then gradually abated in <2 weeks along with improved fetal condition, resulting in a delivery with favorable outcomes at 36 weeks' gestation. Manifestation of mirror syndrome after fetoscopic laser therapy in twin-twin transfusion due to donor hydrops doesn't necessarily predict a poor perinatal outcome.

Screening for aspiration in patients with swallowing disorders is important in preventing complications. The tests used in this regard are insufficient due to silent aspiration relating to abnormal protective reflexes in many patients with swallowing problems. The aim of this study is to determine the predictive values of simple tests in screening for silent aspiration. The reference test used was videofluoroscopic examination on swallowing. In the presence of aspiration (FR+) the presence (ME+) or not (ME-) of a cough of throat clearing was noted. The tests being studied were a nasal test with isotonic saline and swallowing according to a set time. For screening for aspiration the presence of a "wet voice" was considered to be a sign of reduced protective reflexes. 1) During the nasal test, the results are 100% for the positive predictive value (VPp) and 83.3% for the negative predictive value (VPn); 2) These results are respectively 84.6% and 35.9% during the swallowing test. Regarding screening for silent aspiration, 1) during the nasal test, the results are 62.5% for the positive predictive value (VPp) and 36.3% for the negative predictive value (VPn); 2) These results are respectively 54.5% and 26.6% during the swallowing test. This preliminary study points out the lack of predictive value of the nasal test and the swallow test for the silent aspirations. However the results could be useful for other researchers developing other tests in this area.

Children with neurologic impairment (NI) are commonly hospitalized for different types of pneumonia, including aspiration pneumonia. We sought to compare hospital management and outcomes of children with NI diagnosed with aspiration versus nonaspiration pneumonia. A retrospective study of 27 455 hospitalized children aged 1 to 18 years with NI diagnosed with pneumonia from 2007 to 2012 at 40 children's hospitals in the Pediatric Health Information System database. The primary exposure was pneumonia type, classified as aspiration or nonaspiration. Outcomes were complications (eg, acute respiratory failure) and hospital utilization (eg, length of stay, 30-day readmission). Multivariable regression was used to assess the association between pneumonia type and outcomes, adjusting for NI type, comorbid conditions, and other characteristics. In multivariable analysis, the 9.7% of children diagnosed with aspiration pneumonia experienced more complications than children with nonaspiration pneumonia (34.0% vs 15.2%, adjusted odds ratio [aOR] 1.2 (95% confidence interval [CI] 1.1-1.3). Children with aspiration pneumonia had significantly longer length of stay (median 5 vs 3 days; ratio of means 1.2; 95% CI 1.2-1.3); more ICU transfers (4.3% vs 1.5%; aOR 1.4; 95% CI 1.1-1.9); greater hospitalization costs (median $11 594 vs $5162; ratio of means 1.2; 95% CI 1.2-1.3); and more 30-day readmissions (17.4% vs 6.8%; aOR 1.3; 95% CI 1.2-1.5). Hospitalized children with NI diagnosed with aspiration pneumonia have more complications and use more hospital resources than when diagnosed with nonaspiration pneumonia. Additional investigation is needed to understand the reasons for these differences. Copyright © 2016 by the American Academy of Pediatrics.

Fine-needle aspiration biopsy (FNAB) is a simple technique for the investigation of suspicious thyroid nodules. However, low success rates are reported in the literature. The aim of this prospective study was to compare the clinical performance and impact of an automatic aspirator, referred to here as Aspirator 3, to those of the manual technique for the FNAB of clinically suspicious thyroid nodules. One hundred nine consecutive patients with 121 clinically suspicious thyroid nodules underwent a biopsy twice of the same site with the clinically approved Aspirator 3 and with the manual technique. The number of follicular cell formations and the total number of follicular cells in the aspirate were counted using the ThinPrep® method. With the Aspirator 3, the total number and the mean number of extracted cell formations were significantly higher than the values achieved with the manual technique (total: 3222 vs. 1951, p=0.02; mean: 27 vs. 16). The total number of cells that were biopsied was also higher when the Aspirator 3 was utilized (47,480 vs. 23,080, p=0.005). Overall, the Aspirator 3 was superior in 65 biopsies, and the manual technique was superior in 39 biopsies. In terms of cell formations and the total number of cells aspirated, the Aspirator 3 was superior to the manual technique. Further, the Aspirator 3 was more convenient to use and had a greater precision in needle guidance.

Aspiration during any kind of injection is meant to ensure that the needle tip is at the desired location during this blind procedure. While aspiration appears to be a simple procedure, it has generated a lot of controversy concerning the perceived benefits and indications. Advocates and opponents of aspiration both make logically sound claims. However, due to scarcity of available data, there is no evidence that this procedure is truly beneficial or unwarranted. Keeping in view the huge number of injections given worldwide, it is important that we draw attention to key questions regarding aspiration that, up till now, remain unanswered. In this review, we have attempted to gather and present literature on aspiration both from published and non-published sources in order to provide not only an exhaustive review of the subject, but also a starting point for further studies on more specific areas requiring clarification. A literature review was conducted using the US National Institute of Health’s PubMed service (including Medline), Google Scholar and Scopus.

The reaction usually involves fishes of the Scombridae family but, in Hawaii, the reaction is most often due to mahimahi (Coryphaena hippurus). Onset of the reaction is usually abrupt and commonly associated with a prominent flush resembling a sunburn. Headache, tachye to a toxin with histamine-like properties, which is formed because improper refrigeration enables endogenous bacteria to decarboxylate histidine normally present in dark-meat fishes. Symptoms are usually promptly relieved by parenteral antihistamine therapy.

The natural clinical progression of aspiration to eventual pulmonary compromise is not well understood. We hypothesized that dietary modification recommendations, Penetration-Aspiration Scale (PAS) score, and dysphagia etiology would be associated with changes in time to first pulmonary event and overall survival for patients with documented aspiration on radiologic testing. This study identified a cohort of patients with detectable unsensed penetration or aspiration on videofluoroscopic swallowing study (VFSS), and followed this cohort over time for development of pulmonary events and death. We then evaluated the association of aspiration severity and dietary modification recommendations on incidence of these endpoints. Retrospective chart review. A total of 2,616 VFSS exam reports were reviewed from our institution performed between January 1, 2009 and December 31, 2010. Aspiration or unsensed penetration (PAS of 5 or greater) was detected in 564 (21.5%) of these patients, who were then included in the study cohort. Medical records were reviewed retrospectively for development of pulmonary events (pneumonia, pneumonitis, or other life-threatening pulmonary illness) and all-cause mortality for up to 54 months after initial VFSS. Univariate Kaplan-Meier analysis and multivariate Cox regression were performed for time to first pulmonary event and survival predicted by recommended diet, PAS score, and dysphagia etiology. Dysphagia etiology was highly associated with increased development of pulmonary events for some patients, especially those with generalized nonspecific dysphagia due to deconditioning or frailty (hazard ratio [HZ] vs. stroke 2.95, 95% confidence interval [CI]: 1.53-5.69, P = .001) and esophageal dysphagia (HZ: 2.66, 95% CI: 1.17-6.02, P = .019). Dysphagia etiology was also associated with increased mortality for patients with generalized nonspecific dysphagia due to deconditioning or frailty (HZ: 3.32, 95% CI: 2.0-5.52, P < .001), postsurgical

What the physician needs to know about Lynch syndrome: an update.

PubMed

Lynch, Henry T; Lynch, Jane F

2005-04-01

The Lynch syndrome (hereditary nonpolyposis colorectal cancer [HNPCC]), is the most common form of hereditary colorectal cancer (CRC), accounting for 2% to 7% of all CRC cases. The next most common hereditary CRC syndrome is familial adenomatous polyposis (FAP), which accounts for less than 1% of all CRC. Lynch syndrome is of crucial clinical importance due to the fact that it predicts the lifetime risk for CRC and a litany of extra-CRC cancers (of the endometrium, ovary, stomach, small bowel, hepatobiliary tract, upper uroepithelial tract, and brain) through assessment of a well-orchestrated family history. A Lynch syndrome diagnosis is almost certain when a mutation in a mismatch repair gene--most commonly MSH2, MLHI, or, to a lesser degree, MSH6--is identified. Once diagnosed, the potential for significant reduction in cancer-related morbidity and mortality through highly targeted surveillance may be profound. Particularly important is colonoscopy initiated at an early age (ie, 25 years) and repeated annually due to accelerated carcinogenesis. In women, endometrial aspiration biopsy and transvaginal ultrasound are important given the extraordinarily high risk for endometrial and ovarian carcinoma. These cancer control strategies have a major impact on at-risk family members once they have been counseled and educated thoroughly about Lynch syndrome's natural history and their own hereditary cancer risk.

Objective To assess aspirations for physical health over 18 months. To examine whether maintained importance of aspirations for physical health mediated and/or moderated the effect of an intensive intervention on long-term tobacco abstinence. Methods Participants were randomly assigned to an intervention based on self-determination theory or to community care, and provided data at baseline and at 18 and 30 months post-randomization. Results Aspirations for physical health were better maintained over 18 months among participants in the intervention (mean change = .05), relative to community care (mean change = -.13), t = 2.66, p < .01. Maintained importance of aspirations for physical health partially mediated the treatment condition effects on seven-day point prevalence tobacco abstinence (z′ = 1.68, p < .01) and the longest number of days not smoking (z′ = 2.16, p < .01), and interacted with treatment condition to facilitate the longest number of days not smoking (β = .08, p < .05). Conclusion Maintained importance of aspirations for physical health facilitated tobacco abstinence. Practice implications Smokers may benefit from discussing aspirations for physical health within autonomy-supportive interventions. Patients may benefit from discussing aspirations during counseling about therapeutic lifestyle change and medication use. PMID:18838243

A 79-year-old man with a 3-month history of lymphedema of the lower limbs, and diabetes mellitus, was admitted to our hospital for suspected deep venous thrombosis. Several hours after admission, leg pain and purpura-like skin color appeared. On the 2nd hospital day, he was referred to our department for possible acute occlusive peripheral artery disease (PAD) and skin necrosis with blisters; however, computed tomography with contrast showed no occlusive lesions. He had already developed shock and necrotizing deep soft-tissue infections of the left lower leg. Laboratory findings revealed renal dysfunction and coagulation system collapse. Soon after PAD was ruled out, clinical findings suggested necrotizing deep soft-tissue infections, shock state, disseminated intravascular coagulation, and multiple organ failure. These symptoms led to a high suspicion of the well-recognized streptococcal toxic shock syndrome (STSS). With a high suspicion of STSS, we detected Group G β-hemolytic streptococci (GGS) from samples aspirated from the leg bullae, and the species was identified as Streptococcus dysgalactiae subsp. equisimilis (SDSE) by 16S-ribosomal RNA sequencing. However, unfortunately, surgical debridement was impossible due to the broad area of skin change. Despite adequate antimicrobial therapy and intensive care, the patient died on the 3rd hospital day. The M-protein gene (emm) typing of the isolated SDSE was revealed to be stG6792. This type of SDSE is the most frequent cause of STSS due to GGS in Japan. We consider it to be crucial to rapidly distinguish STSS from acute occlusive PAD to achieve life-saving interventions in patients with severe soft-tissue infections.

Adewumi, A; Kays, David W

2008-01-01

Foreign body aspiration (FBA) causes death in more than 300 children every year in the United States. Morbidity and mortality are increased in children due to narrow airways and immature protective mechanisms. Factors to consider in pediatric dentistry are: (1) the patient's age and behavior; (2) presence and extent of disability; (3) local anesthesia; (4) body positioning; and (5) loose teeth. FBA requires prompt recognition and early treatment to minimize potentially serious and sometimes fatal consequences. The purpose of this case report was to describe the aspiration of a stainless steel crown in a 5-year-old boy during conscious sedation. It also discusses how a prompt and accurate diagnosis, early referral, and immediate treatment helped prevent serious complications.

Alpha thalassemia-mental retardation, X-linked (ATR-X) syndrome is a rare genetic disorder with a variety of clinical manifestations. Gastrointestinal symptoms described in this syndrome include difficulties in feeding, regurgitation and vomiting which may lead to aspiration pneumonia, abdominal pain, distention, and constipation. We present a 19-year-old male diagnosed with ATR-X syndrome, who suffered from recurrent colonic volvulus that ultimately led to bowel necrosis with severe septic shock requiring emergent surgical intervention. During 1 year, the patient was readmitted four times due to poor oral intake, dehydration and abdominal distention. Investigation revealed partial small bowel volvulus which resolved with non-operative treatment. Small and large bowel volvulus are uncommon and life-threatening gastrointestinal manifestations of ATR-X patients, which may contribute to the common phenomenon of prolonged food refusal in these patients. © 2015 Wiley Periodicals, Inc.

Gastroesophageal reflux (GER) and aspiration of bile acids have been implicated as non-alloimmune risk factors for the development of bronchiolitis obliterans syndrome (BOS) after lung transplantation. The aim of our study was to investigate the association between GER and gastric aspiration of bile acids and to establish which reflux characteristics may promote aspiration of bile acids into the lungs and may feature as a potential diagnostic tool in identifying lung transplantation (LTx) patients at risk for aspiration. Twenty-four stable LTx recipients were studied 1 year after transplantation. All patients underwent 24-hour ambulatory impedance-pH recording for the detection of acid (pH <4) and weakly acidic (pH 4 to 7) reflux. On the same day, bronchoalveolar lavage fluid (BALF) was collected and then analyzed for the presence of bile acids (Bioquant enzymatic assay). Increased GER was detected in 13 patients, of whom 9 had increased acid reflux and 4 had exclusively increased weakly acidic reflux. Sixteen patients had detectable bile acids in the BALF (0.6 [0.4 to 1.5] micromol/liter). The 24-hour esophageal volume exposure was significantly increased in patients with bile acids compared to patients without bile acids in the BALF. Acid exposure and the number of reflux events (total, acid and weakly acidic) were unrelated to the presence of bile acids in the BALF. However, both nocturnal volume exposure and the number of nocturnal weakly acidic reflux events were significantly higher in patients with bile acids in the BALF. Weakly acidic reflux events, especially during the night, are associated with the aspiration of bile acids in LTx recipients and may therefore feature as a potential risk factor for the development of BOS.

Background Meconium aspiration syndrome (MAS) is a leading cause of morbidity and mortality in term infants. Meconium-stained amniotic fluid (MSAF) occurs in approximately one of every seven pregnancies, but only 5% of neonates exposed to MSAF develop MAS. Why some infants exposed to meconium develop MAS while others do not is a fundamental question. Patients with MSAF have a higher frequency of intra-amniotic infection/inflammation than those with clear fluid. We propose that fetal systemic inflammation is a risk factor for the development of MAS in patients with MSAF. Objective To investigate whether intra-amniotic inflammation and funisitis, the histopathologic landmark of a fetal inflammatory response, predispose to MAS. Study Design A prospective cohort study was conducted from 1995 through 2009. Amniotic fluid (AF) samples (n=1,281) were collected at the time of cesarean delivery from women who delivered singleton newborns at term (gestational age ≥38 weeks). Intra-amniotic inflammation was diagnosed if the AF concentration of matrix metalloproteinase-8 (MMP-8) was >23 ng/ml. Funisitis was diagnosed by histologic examination if inflammation was present in the umbilical cord. Results The prevalence of MSAF was 9.2% (118/1,281), and 10.2% (12/118) of neonates exposed to MSAF developed MAS. There were no significant differences in the median gestational age or umbilical cord arterial pH at birth between neonates who developed MAS and those who did not (each p > 0.1). Mothers whose newborns developed MAS had a higher median AF MMP-8 (456.8 ng/ml vs.157.2 ng/ml; p < 0.05). Newborns exposed to intra-amniotic inflammation had a higher rate of MAS than those who were not exposed to intra-amniotic inflammation [13.0% (10/77) vs. 0% (0/32), p = 0.03], as did those exposed to funisitis [31.3% (5/16) vs. 7.3% (6/82), relative risk, 4.3; 95% confidence interval, 1.5–12.3]. Among the 89 newborns for whom both AF and placental histology were available, MAS was more

Midline structural defects in the neural axis can give rise to neuro-ophthalmic symptoms. We report a rare case of keyhole aqueduct syndrome presenting after two years of severe cough due to gastroesophageal reflux disease. A 58-year-old woman with a 2-year history of daily, severe cough presented to the neuro-ophthalmology clinic with progressive diplopia and oscillopsia. Examination revealed a 1-2 Hz down-beating nystagmus in primary gaze that worsened with left, right, and down gazes. Gaze evoked nystagmus and mild paresis were also seen with up gaze. There was an incomitant left hypertropia due to skew deviation that worsened with right and up gazes and improved with down gaze. She also had a right-sided ptosis and a 3 mm anisocoria not due to cranial nerve 3 paresis or Horner's syndrome. Brain magnetic resonance imaging showed a 1.5 mm × 11.7 mm × 6 mm midline cleft in the ventral midbrain communicating with the cerebral aqueduct, consistent with keyhole aqueduct syndrome. Her nystagmus and diplopia improved with oral acetazolamide treatment, at high doses of 2500-3000 mg per day. We report the first case of midbrain keyhole aqueduct syndrome with ocular motor and other neuro-ophthalmic manifestations associated with severe cough. Although her cough was effectively treated and intracranial pressure measurement was normal, her ophthalmic symptoms continued to progress, which is common in previous cases reported. Treatment with acetazolamide led to significant improvement, supporting the use of acetazolamide in this rare condition.

We report a rare case of iliac vein compression syndrome caused by urethral calculus. A 71-year-old man had a history of urethral stenosis. He complained of bilateral leg edema and dysuria for 1 week. Physical examination revealed bilateral distention of the superficial epigastric veins, so obstruction of both common iliac veins or the inferior vena cava was suspected. Plain abdominal computed tomography showed a calculus in the pendulous urethra, distention of the bladder (as well as the right renal pelvis and ureter), and compression of the bilateral common iliac veins by the distended bladder. Iliac vein compression syndrome was diagnosed. Bilateral iliac vein compression due to bladder distention (secondary to neurogenic bladder, benign prostatic hyperplasia, or urethral calculus as in this case) is an infrequent cause of acute bilateral leg edema. Detecting distention of the superficial epigastric veins provides a clue for diagnosis of this syndrome. PMID:25802794

Necrotizing fasciitis is known to be a highly lethal infection of deep-seated subcutaneous tissue and superficial fascia. Reports of necrotizing fasciitis due to Streptococcus pneumoniae are exceedingly rare. We report a case of necrotizing fasciitis in a 62-yr-old man with liver cirrhosis and diabetes mellitus. He presented with painful swelling of left leg and right hand. On the day of admission, compartment syndrome was aggravated and the patient underwent surgical exploration. Intra-operative findings revealed necrotizing fasciitis and cultures of two blood samples and wound aspirates showed S. pneumoniae. The patient died despite debridement and proper antimicrobial treatment. To the best of our knowledge, this is the first case of fatal necrotizing fasciitis with meningitis reported in Korea. We also review and discuss the literature on pneumococcal necrotizing fasciitis. PMID:21218041

Intractable aspiration is a serious, often life-threatening condition due to its potential impact on pulmonary function. Aspiration requires therapeutic measures, starting with conservative management but often necessitating surgical treatment. The basic surgical principle is to separate the alimentary and respiratory tracts through a variety of procedures which, unfortunately, nearly all result in the loss of phonation, with the exception of total laryngectomy (TL) which includes the placement of an indwelling voice prosthesis. In this study, we present a modified laryngotracheal separation (LTS) technique that, we believe, offers multiple advantages compared to standard TL. After reviewing the medical records of 35 patients with intractable aspiration who have undergone LTS, we describe the surgical technique and present the postoperative result. In a second surgical procedure about two months following LTS, we aimed to achieve voice restoration by placement of an indwelling voice prosthesis. Intractable aspiration was successfully treated in all patients. Placement of an indwelling voice prosthesis during a second operation was successful in 15 patients, representing the largest reported cohort thus far. LTS is a reliable surgical technique to treat intractable aspiration, with restoration of oral intake, thereby improving the general condition and quality of life of these unfortunate patients. Furthermore, voice restoration can be achieved in selected patients, by placement of a voice prosthesis.

Micropipette aspiration and confocal fluorescence microscopy were used to study the structure and mechanical properties of calcium alginate hydrogel beads (A beads), as well as A beads that were additionally coated with poly-L-lysine (P) and sodium alginate (A) to form, respectively, AP and APA hydrogels. A beads were found to continue curing for up to 500 h during storage in saline, due to residual calcium chloride carried over from the gelling bath. In subsequent saline washes, micropipette aspiration proved to be a sensitive indicator of gel weakening and calcium loss. Aspiration tests were used to compare capsule stiffness before and after citrate extraction of calcium. They showed that the initial gel strength is largely due to the calcium alginate gel cores, while the long term strength is solely due to the poly-L-lysine-alginate polyelectrolyte complex (PEC) shells. Confocal fluorescence microscopy showed that calcium chloride exposure after PLL deposition led to PLL redistribution into the hydrogel bead, resulting in thicker but more diffuse and weaker PEC shells. Adding a final alginate coating to form APA capsules did not significantly change the PEC membrane thickness and stiffness, but did speed the loss of calcium from the bead core. © 2013.

Clinical finding of cutis laxa, characterized by wrinkled, redundant, sagging, nonelastic skin, is of growing significance due to its occurrence in several different inborn errors of metabolism (IEM). Metabolic cutis laxa results from Menkes syndrome, caused by a defect in the ATPase copper transporting alpha (ATP7A) gene; congenital disorders of glycosylation due to mutations in subunit 7 of the component of oligomeric Golgi (COG7)-congenital disorders of glycosylation (CDG) complex; combined disorder of N- and O-linked glycosylation, due to mutations in ATPase H+ transporting V0 subunit a2 (ATP6VOA2) gene; pyrroline-5-carboxylate reductase 1 deficiency; pyrroline-5-carboxylate synthase deficiency; macrocephaly, alopecia, cutis laxa, and scoliosis (MACS) syndrome, due to Ras and Rab interactor 2 (RIN2) mutations; transaldolase deficiency caused by mutations in the transaldolase 1 (TALDO1) gene; Gerodermia osteodysplastica due to mutations in the golgin, RAB6-interacting (GORAB or SCYL1BP1) gene; and mitogen-activated pathway (MAP) kinase defects, caused by mutations in several genes [protein tyrosine phosphatase, non-receptor-type 11 (PTPN11), RAF, NF, HRas proto-oncogene, GTPase (HRAS), B-Raf proto-oncogene, serine/threonine kinase (BRAF), MEK1/2, KRAS proto-oncogene, GTPase (KRAS), SOS Ras/Rho guanine nucleotide exchange factor 2 (SOS2), leucine rich repeat scaffold protein (SHOC2), NRAS proto-oncogene, GTPase (NRAS), and Raf-1 proto-oncogene, serine/threonine kinase (RAF1)], which regulate the Ras-MAPK cascade. Here, we further expand the list of inborn errors of metabolism associated with cutis laxa by describing the clinical presentation of a 17-month-old girl with Leigh-like syndrome due to enoyl coenzyme A hydratase, short chain, 1, mitochondria (ECHS1) deficiency, a mitochondrial matrix enzyme that catalyzes the second step of the beta-oxidation spiral of fatty acids and plays an important role in amino acid catabolism, particularly valine.

Amebic liver abscess (ALA) is a common and serious problem in our country. There are only a few controlled trials on the efficacy and advantages of combination therapy with percutaneous needle aspiration and pharmacotherapy, over pharmacotherapy alone for amebic liver abscess. This study was conducted to compare the efficacy of two different treatment modalities i.e. drug treatment alone vs. drug treatment and aspiration of abscess cavity in patients with small (up to 5 cm) and large (5 cm to 10 cm) size ALA. This is one of the largest single center, prospective, randomized studies comparing the efficacy of aspiration in ALA. (i) Mean body temperature, liver tenderness, total leukocyte count (TLC), serum alanine aminotransferase (ALT) and liver span were significantly decreased in the aspiration group on days 8 and 15 as compared to non-aspiration group especially in large abscess (5 cm to 10 cm). (ii) Abscess cavity maximum diameter decreased significantly in aspiration group on days 8 and 15, and 1 month & 3 months in large abscess (5cm to 10 cm). (i) Needle aspiration along with metronidazole hastens clinical improvement especially in large (5 cm up to 10 cm) cavities in patients with ALA. (ii) Aspiration is safe and no major complications occurred. (iii) Hence, combination therapy should be the first choice especially in large ALA (5 cm to 10 cm).

A 21-year-old woman presented with acute onset of upper abdominal pain. A diagnosis of Peutz-Jeghers syndrome (PJS) was made based on the clinical picture of perioral pigmentation with imaging findings of transient jejunojejunal intussusceptions and small bowel polyps, and confirmed by characteristic histopathological appearances of Peutz-Jeghers polyps. PJS is a rare hereditary condition characterised by unique hamartomatous polyps, perioral mucocutaneous pigmentations, and increased susceptibility to gastrointestinal and extraintestinal neoplasms. Patients usually present with recurrent abdominal pain due to intussusception caused by polyps. Other modes of presentations include rectal bleeding and melaena. We describe the imaging findings of PJS and provide a brief review of bowel polyposis syndromes. The latter are relatively rare disorders characterised by multiple polyps in the large or small intestine, with associated risk of malignancies and other extraintestinal manifestations. Awareness of the manifestations and early diagnosis of these syndromes is crucial to prevent further complications.

A new posterior iliac puncture/aspiration needle.

PubMed

Islam, Anwarul

2016-03-25

The needles that are currently used for obtaining bone marrow aspirate samples from the posterior ilium are typically those of 1930s vintage (eg, Klima, Salah or similar needles), which were specifically designed for sternal aspiration. These needles are not designed to obtain bone marrow aspirate samples from the posterior ilium and as a result they are unsatisfactory particularly if the patient is large or obese. A new posterior iliac puncture/aspiration needle has therefore been designed, which is particularly suited for bone marrow aspiration from the posterior ilium. The needle was tested on five cadavers and on five patients. The design and construction of the needle was found to be satisfactory and a marked improvement over the conventional sternal puncture needles particularly when large or obese patients were concerned. The new posterior iliac bone marrow aspiration needle has advantages that overcome the limitations of using a conventional sternal puncture needle to obtain marrow aspirates from the posterior ilium.

Up to 77% of Down syndrome (DS) patients have associated structural or functional gastrointestinal abnormalities. Functional disturbances, such as processes affecting the enteric nervous system, can often affect the outcome of corrective surgical procedures. Recently, an association between DS and achalasia has been reported. In this report we present a 28-year-old male patient with a history of Down syndrome and achalasia, who presented with recurrent dysphagia, gastroesophageal reflux, and recurrent aspirations. The patient had previously undergone a laparoscopic Heller myotomy with Dor fundoplication. Unfortunately, despite this surgery, he continued to require multiple esophageal dilations, and intraesophageal administration of Botox therapy. Additionally, there were numerous subsequent hospital admissions for recurrent aspiration pneumonia. Evaluation revealed an incomplete myotomy and a revision long Heller myotomy was successfully performed intraabdominally and he is now symptom and aspiration free.

The trisomy 18 syndrome, also known as Edwards syndrome, is a common chromosomal disorder due to the presence of an extra chromosome 18, either full, mosaic trisomy, or partial trisomy 18q. The condition is the second most common autosomal trisomy syndrome after trisomy 21. The live born prevalence is estimated as 1/6,000-1/8,000, but the overall prevalence is higher (1/2500-1/2600) due to the high frequency of fetal loss and pregnancy termination after prenatal diagnosis. The prevalence of trisomy 18 rises with the increasing maternal age. The recurrence risk for a family with a child with full trisomy 18 is about 1%. Currently most cases of trisomy 18 are prenatally diagnosed, based on screening by maternal age, maternal serum marker screening, or detection of sonographic abnormalities (e.g., increased nuchal translucency thickness, growth retardation, choroid plexus cyst, overlapping of fingers, and congenital heart defects ). The recognizable syndrome pattern consists of major and minor anomalies, prenatal and postnatal growth deficiency, an increased risk of neonatal and infant mortality, and marked psychomotor and cognitive disability. Typical minor anomalies include characteristic craniofacial features, clenched fist with overriding fingers, small fingernails, underdeveloped thumbs, and short sternum. The presence of major malformations is common, and the most frequent are heart and kidney anomalies. Feeding problems occur consistently and may require enteral nutrition. Despite the well known infant mortality, approximately 50% of babies with trisomy 18 live longer than 1 week and about 5-10% of children beyond the first year. The major causes of death include central apnea, cardiac failure due to cardiac malformations, respiratory insufficiency due to hypoventilation, aspiration, or upper airway obstruction and, likely, the combination of these and other factors (including decisions regarding aggressive care). Upper airway obstruction is likely more common

Foreign body aspiration can occur in any age group, but it is more commonly seen in children. In adults, there is usually a predisposing condition that poses a risk of aspiration. If aspiration occurs, prompt diagnosis and extraction of the foreign body is needed to prevent early and late complications. We report a rare case of neglected foreign body aspiration in a 45-year-old schizophrenic opium addicted patient, which resulted in an occlusive lesion in the bronchus, mimicking bronchial carcinoma. © The Author(s) 2016.

Perc & Wang demonstrated that aspiring to be the fittest under conditions of pairwise strategy updating enhances network reciprocity in structured populations playing 2×2 Prisoner's Dilemma games (Z. Wang, M. Perc, Aspiring to the fittest and promoted of cooperation in the Prisoner's Dilemma game, Physical Review E 82 (2010) 021115; M. Perc, Z. Wang, Heterogeneous aspiration promotes cooperation in the Prisoner's Dilemma game, PLOS one 5 (12) (2010) e15117). Through numerical simulations, this paper shows that network reciprocity is even greater if heterogeneous aspirations are imposed. We also suggest why heterogeneous aspiration fosters network reciprocity. It distributes strategy updating speed among agents in a manner that fortifies the initially allocated cooperators' clusters against invasion. This finding prompted us to further enhance the usual heterogeneous aspiration cases for heterogeneous network topologies. We find that a negative correlation between degree and aspiration level does extend cooperation among heterogeneously structured agents.

Objective The aim of this study was to compare the risk factors associated with mild/moderate meconium aspiration syndrome (MAS) with those associated with severe in meconium-stained term neonates. Methods Consecutive singleton term neonates (n=671) with meconium staining at birth from all deliveries (n=14,666) in our institution from January 2006 to December 2012 were included. Both maternal and neonatal variables were examined. Among the study population, for women who underwent the trial of labor (n=644), variables associated with labor were also examined. These variables were compared between the mild/moderate MAS group, the severe MAS group, and the MAS-absent group. Results MAS developed in 10.6% (71/671) of neonates with meconium staining at birth. Among the neonates with MAS, 81.7% had mild MAS, 5.6% had moderate MAS, and 12.7% had severe MAS. The presence of minimal variability was significantly increased in both the mild/moderate and the severe MAS groups. The frequencies of nulliparity, fetal tachycardia, and intrapartum fever were significantly increased in the mild/moderate MAS group, but not in the severe MAS group. While a longer duration of the second stage of labor was significantly associated with mild/moderate MAS, severe MAS was associated with a shorter duration of the second stage. Notably, low mean cord pH (7.165 [6.850-7.375]) was significantly associated with mild/moderate MAS, but not with severe MAS (7.220 [7.021-7.407]) compared with the absence of MAS (7.268 [7.265-7.271]). Conclusion Our data suggest the development of severe MAS is not simply a linear extension of the same risk factors driving mild/moderate MAS. PMID:25629015

To explore the methods and results of surgical management for refractory dysphagia and aspiration. The clinical data of 24 refractory dysphagia and aspiration patients who accepted surgical management were retrospectively analysed. Twenty-four refractory dysphagia and aspiration patients accepted 26 operations between 2001 and 2014. Of the 26 operations, 17 were cricopharyngeal myectomy (CPM), 6 were scarectomy, 3 were laryngeal-tracheal separation. No severe complications occurred. Assessments of dysphagia were completed in 18 operations before and after operation. Aspiration scores of videofluoroscopic swallowing study (VFSS) were 4.50 [4.00;7.00] vs 2.00 [1.00; 3.25], P = 0.000; swallow dysfunction scroes of VFSS were 5.00 [4.00; 12.00] vs 1.00 [1.50; 10.00], P = 0.001; aspiration scores of fibroptic endoscopic evaluation of swallowing (FEES) were 4.00 [5.00; 7.00] vs 2.00 [1.75; 3.00], P = 0.000. But the surgical results for post radiotherapy dysphagia were not successful (n = 5): aspiration scores of VFSS were 7.00 [6.50; 8.00] vs 6.00 [2.00; 7.50], P = 0.109;swallow dysfunction scroes of VFSS were 12.00 [10.50; 12.00] vs 12.00 [7.50; 12.00], P = 0.180;aspiration scores of FEES were 7.00 [6.50; 8.00] vs 6.00 [2.00; 7.50], P = 0.109. Surgical management was effective for refractory dysphagia and aspiration, but the surgical indication selection should be strict.

[New treatment concept for children with thoracic insufficiency syndrome due to congenital spine deformity].

Children with congenital thoracic scoliosis associated with fused ribs and unilateral unsegmented bars adjacent to convex hemivertebrae will inevitably develop thoracic insufficiency syndrome and curve progression with hemithorax compression without treatment. It is assumed that the concave side of such curves and their unilateral unsegmented bars do not grow. In the past early spinal fusion was performed with consecutive short thoracic spines and loss of lung volume. Little attention has been paid to lung function. These patients often suffered from lung failure and early death due to a small thorax. A new surgical technique is based on an indirect deformity correction and enlargement of the thorax due to a longitudinal implant, the vertical expandable prosthetic titanium rib (VEPTR). The spine is not fused, thus promoting growth of the spine, the thorax and the lungs. Elongation of the implant is done every six months. Since 2002 this method has been performed on fifteen children in Basel as the first European center. Patients (mean age 6 years; 11 months to 12 years) were suffering from thoracic insufficiency syndrome due to unilateral unsegmented bars with fused ribs (n = 4), absent ribs (n = 2), bilaterally fused ribs (n = 2), hemivertebrae (n = 3) or neuromuscular scoliosis (n = 6). Doing fifteen primarily implantations and thirteen elongations there were three complications (two hook dislocations, one skin breakage). All patients improved cosmetically, functionally and radiologically which was shown on X-rays as a reduction of the Cobb angle from an average of 76 degrees (40-110 degrees ) to 55 degrees (30-67 degrees ). Expansion thoracoplasty and VEPTR implantation is a new treatment concept for children with thoracic insufficiency syndrome due to spinal deformities, which is based on distraction and expansion of the thorax thus allowing growth of the spine, the thorax and probably lungs. Presently it seems to be superior to any other method for the

Suprapubic bladder aspiration in neonates is a simple, safe, and useful technique for collection of sterile urine. The procedure can be performed in the hospital or office. Neither sedation nor local anesthetic is required. Suprapubic bladder aspiration of urine is the preferred method of collecting urine for culture in septic neonates. The technique is also indicated to verify urinary tract infection in neonates. Suprapubic bladder aspiration is contraindicated in the presence of abdominal distension or an empty bladder. Carefully and properly performed, the risk of complications should be negligible, and the success rate in obtaining urine is 90%. ImagesFigure 1Figure 2 PMID:21263980

Fiberoptic bronchoscopic treatment of blood aspiration and use of sugammadex in a patient with epistaxis

PubMed Central

Ryu, Taeha; Kim, Dong Hyuck; Byun, Sung Hye

2018-01-01

Abstract Rationale: In patients with oropharyngeal and nasopharyngeal bleeding, blood aspiration can make airway management difficult and lead to severe pulmonary complications. Patient concerns: A 44-year-old male patient with recurrent epistaxis underwent surgery for hemostasis. The patient aspirated blood through the endotracheal tube when he hiccupped during the surgery. Diagnosis: The patient was diagnosed with blood aspiration after intraoperative fiberoptic bronchoscopy revealed a blood clot and viscous mucus in the airways, but no sign of active bleeding. Interventions: Tracheobronchial suctioning and irrigation with normal saline was performed through the bronchoscope to remove the aspirated blood clot. Prior to emergence from anesthesia, sugammadex was administered to induce complete neuromuscular recovery and enable the patient to cough up any blood remaining in the airways. Outcomes: The patient was successfully extubated and fully recovered with no complications. Lessons: Blood aspiration due to oropharyngeal or nasopharyngeal bleeding can be diagnosed and treated by tracheobronchial suctioning via fiberoptic bronchoscopy. In addition, sugammadex can enable patients to recover spontaneous breathing, facilitate extubation, and enable patients to cough up any blood remaining in the airways. PMID:29642212

Adenocorticotropic hormone (ACTH)-dependent Cushing's syndrome in infancy is extremely rare. We describe the case of a sacro-coccygeal ectopic ACTH-secreting immature teratoma in an infant who also presented the triad of defects characteristic of Currarino syndrome. A girl was born with a large immature teratoma in the sacro-coccygeal region associated with anal atresia. At the age of 7 days, the concentration of α-fetoprotein (AFP) was above the age-specific normal range. Two non-radical surgical excisions of the tumour were performed. At the age of 7 months, she developed polyphagia, acne, hirsutism, hypertension and hypokalemia with elevated ACTH and absence of serum cortisol circadian rhythm. Immunostaining of tumour tissue showed ACTH-immunoreactive cells. Due to unsuccessful therapy with ketoconazole and resistance to antihypertensive medications [blood pressure (BP) 210/160 mmHg], metyrapone was administered, which controlled her ACTH and cortisol levels in the normal range. Following further removal of tumour bulk after three operations during the first year of life, there was a decrease of BP to normal values. A rare case of ectopic ACTH syndrome causing Cushing's syndrome in infancy in the context of Currarino syndrome is reported. Radical surgery has resulted in excision of the tumour and current control of Cushing's syndrome.

Characteristics and Treatments of Large Cystic Brain Metastasis: Radiosurgery and Stereotactic Aspiration

Brain metastasis represents one of the most common causes of intracranial tumors in adults, and the incidence of brain metastasis continues to rise due to the increasing survival of cancer patients. Yet, the development of cystic brain metastasis remains a relatively rare occurrence. In this review, we describe the characteristics of cystic brain metastasis and evaluate the combined use of stereotactic aspiration and radiosurgery in treating large cystic brain metastasis. The results of several studies show that stereotactic radiosurgery produces comparable local tumor control and survival rates as other surgery protocols. When the size of the tumor interferes with radiosurgery, stereotactic aspiration of the metastasis should be considered to reduce the target volume as well as decreasing the chance of radiation induced necrosis and providing symptomatic relief from mass effect. The combined use of stereotactic aspiration and radiosurgery has strong implications in improving patient outcomes. PMID:25977901

Unsuitable value of abdominal fat tissue aspirate examination for the diagnosis of amyloidosis in long-term hemodialysis patients.

Abdominal fat tissue aspiration was used in 22 long-term hemodialysis patients (5-17 years). Fourteen of these patients had carpal tunnel syndrome and amyloid deposits of beta 2-microglobulin in the synovium. One patient had a spontaneous rupture of the spleen with amyloid deposits in spleen vessels. Seven other patients presented carpal tunnel syndrome and/or articular pains, and radiological lytic lesions in bone, strongly suggesting an amyloid origin. As a control group, in 22 patients with biopsy-proven amyloidosis, abdominal fat tissue aspirates were performed and were studied under the same conditions: by light microscopy these tissues were stained with Congo red and examined with a polarizing microscope; these specimens were also studied by electron microscopy. In all hemodialyzed patients, no amyloid deposit was present in fat tissue with Congo red staining and by electron microscopy. On the contrary, amyloid was observed in 17 of 22 cases in other types of amyloidosis. It seems that this method which has been proved to be simple and sensitive for the diagnosis of systemic amyloidosis is not a good marker for the presence of amyloid in long-term hemodialysis patients.

Aging-Related Geniohyoid Muscle Atrophy Is Related to Aspiration Status in Healthy Older Adults

PubMed Central

2013-01-01

Background. Age-related muscle weakness due to atrophy and fatty infiltration in orofacial muscles may be related to swallowing deficits in older adults. An important component of safe swallowing is the geniohyoid (GH) muscle, which helps elevate and stabilize the hyoid bone, thus protecting the airway. This study aimed to explore whether aging and aspiration in older adults were related to GH muscle atrophy and fatty infiltration. Method. Eighty computed tomography scans of the head and neck from 40 healthy older (average age 78 years) and 40 younger adults (average age 32 years) were analyzed. Twenty aspirators and 20 nonaspirators from the 40 older adults had been identified previously. Two-dimensional views in the sagittal and coronal planes were used to measure the GH cross-sectional area and fatty infiltration. Results. GH cross-sectional area was larger in men than in women (p < .05). Decreased cross-sectional area was associated with aging (p < .05), and cross-sectional area was significantly smaller in aspirators compared with nonaspirators, but only among the older men (p < .01). Increasing fatty infiltration was associated with aging in the middle (p < .05) and posterior (p < .01) portions of the GH muscle. There was no significant difference in fatty infiltration of the GH muscle among aspirators and nonaspirators. Conclusion. GH muscle atrophy was associated with aging and aspiration. Fatty infiltration in the GH muscle was increased with aging but not related to aspiration status. These findings suggest that GH muscle atrophy may be a component of decreased swallowing safety and aspiration in older adults and warrants further investigation. PMID:23112114

Cushing syndrome in a young woman due to primary pigmented nodular adrenal disease.

To report a case of Cushing syndrome due to apparently sporadic primary pigmented nodular adrenal disease in a young woman. We describe the clinical, biochemical, radiologic, and histologic findings of Cushing syndrome due to the rare condition of primary pigmented nodular adrenal disease. A 30-year-old woman presented with a 2-year history of worsening itch without rash over her shoulders and arms and weight gain, particularly around the abdomen and face. Careful questioning did not elicit any history of exogenous glucocorticoid use (systemic or topical), including hydrocortisone. On examination, the patient had a slightly rounded and plethoric face, a small buffalo hump, central adiposity, and thin skin with a few small striae on her inner thighs. No features of the Carney complex were observed. Investigations showed hypercortisolism with suppressed corticotropin and normal adrenal imaging despite documentation of enlarged adrenal glands at removal. High-dose dexamethasone administration was followed by a decrease in urinary free cortisol excretion rather than a paradoxical rise as previously reported in primary pigmented nodular adrenal disease. No mutations were detected in the PRKAR1A gene. Primary pigmented nodular adrenal disease should be suspected in patients with corticotropin-independent Cushing syndrome who have normal adrenal imaging. The role of genetic testing in apparently sporadic cases is not established, but cumulative experience may be helpful in defining the frequency of PRKAR1A mutations.

Aspiration and sclerotherapy versus hydrocelectomy for treatment of hydroceles.

PubMed

Beiko, Darren T; Kim, Dennis; Morales, Alvaro

2003-04-01

To compare aspiration and sclerotherapy using sodium tetradecylsulfate (STDS) with open hydrocelectomy in the treatment of hydroceles with regard to safety, efficacy, and cost-effectiveness. Patients with symptomatic hydroceles were prospectively enrolled in an aspiration and sclerotherapy protocol between October 1998 and June 2000. Patients in this group underwent percutaneous aspiration followed by sclerotherapy with an STDS-based solution. This group was compared with a group of patients chosen consecutively who underwent hydrocelectomy between December 1996 and August 1999. Primary outcome measures included patient satisfaction and procedural success. Secondary outcome measures included complications and comparative costs. A total of 27 patients with 28 hydroceles were enrolled in the aspiration and sclerotherapy protocol and compared with 24 patients with 25 hydroceles in the hydrocelectomy group. Mean follow-up for the aspiration and sclerotherapy group and hydrocelectomy group was 8.9 and 16.4 months, respectively. Patient satisfaction was 75% for aspiration and sclerotherapy and 88% for hydrocelectomy. The overall success rate for aspiration and sclerotherapy was 76% compared with 84% for hydrocelectomy. The complication rate was only 8% in the aspiration and sclerotherapy group, but 40% in the hydrocelectomy group. Comparative costs per procedure demonstrated that hydrocelectomy was almost ninefold more expensive than aspiration and sclerotherapy. In the treatment of hydroceles, aspiration and sclerotherapy with STDS represents a minimally invasive approach that is simple, inexpensive, and safe but less effective than hydrocelectomy. Aspiration and sclerotherapy is a viable first-line therapeutic option in the management of hydroceles.

Coronary angiogram in a young man with history of STEMI with delayed presentation revealed subtotal occlusion of left anterior descending artery (LAD) with large thrombotic filling defect distal to the critical lesion. PCI was preferred without delay because of ongoing chest pain. Several runs of thrombus aspiration failed to detect any visible thrombus. However, the immediate angiogram after thrombus aspiration showed complete distal embolization of the thrombus which could have been achieved by Dottering or balloon dilatation. In contrary to the general perception, does thrombus aspiration push more thrombus than it can aspirate? Copyright © 2016 Cardiological Society of India. Published by Elsevier B.V.

Japan became a superaging society. We have been putting a new focus on locomotive syndrome and frailty. The prevention and treatment of locomotive syndromes, such as osteoarthritis, degenerative spondylosis, lumbar canal stenosis, osteoporosis, upper extremity diseases, rheumatoid arthritis, and many other disorders of the locomotive organs are important. Because, the locomotive syndrome results in deterioration of the exercise function and loss of mental and physical health. The aim of locomotive syndrome exercises are: to reduce pain, to restore and improve joint function. We need to take a comprehensive approach to locomotive syndrome, including lifestyle modification, muscle exercise, stretching and therapeutic exercise.

Aspiration and sclerotherapy: a nonsurgical treatment option for hydroceles.

We demonstrated that hydrocele aspiration and sclerotherapy with doxycycline is an effective and safe nonsurgical treatment option for hydrocele correction. The medical records of patients who underwent hydrocele aspiration and sclerotherapy were analyzed in a retrospective cohort study for success rates as well as improvement in scrotal size and discomfort after a single hydrocele aspiration and sclerotherapy treatment. Patients who reported decreased scrotal size, improved physical symptoms and satisfaction with the procedure were considered as having success with hydrocele aspiration and sclerotherapy. A total of 29 patients (mean age 52.8 years) presenting with 32 nonseptated hydroceles underwent hydrocele aspiration and sclerotherapy with doxycycline between 2005 and 2012. Of the hydroceles 27 (84%) were successfully treated with a single aspiration and sclerotherapy procedure. Overall mean followup was 20.8 months. Three patients reported moderate pain which resolved in 2 to 3 days. Of those patients in whom hydrocele aspiration and sclerotherapy failed, 1 had hydrocele successfully resolved with a second aspiration and sclerotherapy treatment, 3 did not have success with a second procedure and underwent hydrocelectomy, and 1 wanted immediate surgical correction. Hydrocele aspiration and sclerotherapy was successful in correcting 84% of simple nonseptated hydroceles with a single treatment. This result is an increase from previously reported success rates involving a single hydrocele aspiration and sclerotherapy procedure with tetracycline (75%). The success rate of a single hydrocele aspiration and sclerotherapy procedure is similar to the reported success rates involving hydrocelectomy while avoiding the hospital expense and many other complications. We conclude that the hydrocele aspiration and sclerotherapy procedure is a reasonable, nonsurgical and underused treatment option for nonseptated simple hydroceles.

Rates of ventilator-associated pneumonia (VAP) are highest among patients intubated on an emergency basis following trauma. We reported previously a retrospective analysis demonstrating an association between subjective aspiration and VAP after pre-hospital intubation. We hypothesize that by directing paramedics to note features of aspiration at intubation, we will confirm prospectively the association between pre-hospital aspiration and subsequent pneumonia in trauma patients. Paramedics collected data regarding aspiration at the time of intubation. All intubated patients admitted to a level 1 trauma center intensive care unit (ICU) were included. Data comprised a clinical impression of pre-hospital aspiration, as well as the presence and timing of blood and emesis in the airway. Injury severity, co-morbidities, and outcomes were collected from the trauma registry. Healthcare-associated pneumonia (HAP) was identified by medical record review of both bronchoalveolar lavage culture results and discharge diagnosis. Descriptive statistics and univariate analysis of outcomes by aspiration status, as well as covariable adjustment using propensity scores, were performed. Of the 228 patients, 89 (39%) were determined by paramedics to have aspirated. The majority of those who aspirated (84 [94%]) did so prior to intubation. Patients who aspirated had higher Injury Severity Scores than those who did not aspirate (25.0 ± 1.7 vs. 21.9 ± 1.5 points; p=0.04) and lower preintubation Glasgow Coma Scale scores (8.2 ± 0.50 vs. 9.6 ± 0.40; p=0.02). Of the 89 patients who aspirated around the time of intubation, 14 (16%) developed HAP vs. five (3.6%) of those who did not aspirate (p<0.01). We observed non-significant increases in mortality rate, ICU length of stay (LOS) and duration of mechanical ventilation after aspiration (deaths: 21 [23.6%] vs. 23 [16.6%]; p=0.19; ICU LOS: 5.3 ± 0.9 vs. 4.1 ± 0.5 days; p=0.13; duration of mechanical ventilation: 5.3 ± 1.2 vs. 3.2 ± 0

The occupational aspirations and expectations of two populations of boys in grades 2, 4, 6, and 8 were examined in order (1) to describe what is unique about the development of job preferences among urban ghetto children who live in settings where many adult males are not well attached to the labor force and (2) to examine 6 reasons for any age- and population-dependent patterns there might be in job aspirations and job expectations. Findings show that boys tend to be more realistic about occupational aspirations and expectations the older they are; that from second grade on the occupational expectations of inner-city boys mirror existing race and class differences in adult job holdings; that the gap between occupational aspirations and expectations is greater for the ghetto boys and remains roughly constant in size across the grades examined; and that the lower occupational expectations of the inner-city boys are strongly related to their lower educational expectations, with these educational expectations being associated with fewer poor boys having a biological father at home and with more of these boys seeing obstacles to success in the local social setting. But, the lower occupational expectations of the ghetto boys are not due to having fewer positive role models or believing that schooling will not pay off for them in the future as it does for others.

Liposuction: more curettage than aspiration.

PubMed

Mottura, A A

1991-01-01

After infiltration with epinephrine solution in each adipose area, an 8- or 10-mm cannula, without the suction tube connected, was introduced. With a curettage maneuver and by directing the cannula upward, the fat began to come out spontaneously. After obtaining a considerable amount of fat, the suction tube was connected and the remaining fat tissue aspirated at low suction power (250 mm Hg). With this curettage maneuver adiposity of the abdomen, knees, and trochanteric areas can be reduced. However, in the back, buttocks, or thighs, where adiposity is more fibrous, aspiration is needed from the start in almost every case, but always at low-power suction. This procedure is indicated in particular for the face and neck and for secondary liposuction. The fact that fat comes out easily through the cannula (without suction) demonstrates that the curettage maneuver is more important than the aspiration. Only with curettage can a considerable amount of fat be removed. No fat is removed when aspiration of 1 atm without a curettage maneuver is used. Suction only helps to remove fat already mobilized and free in the cannula. Our experience includes 34 patients.

Upper aerodigestive tract cancer and the lung: a tale of two aspirations.

PubMed

Vaideeswar, P; Ghodke, R

2012-01-01

Patients with upper aerodigestive epithelial cancers frequently develop second primary cancers due to common risk factors or develop distant metastases depending on the locoregional status of the primary tumor. In most instances, the organ affected is the lung. Pulmonary spread usually occurs due to hematogenous or lymphatic dissemination. The following is a report of two patients with upper aerodigestive tract squamous cell carcinomas who developed lung metastases due to aspiration, a route not well documented in recent literature.

Aspirations, Expectations and Delinquency: The Moderating Effect of Impulse Control.

Although prior research finds a robust link between delinquent behavior and expectations, or an adolescent's perceived likelihood of obtaining one's future goals, fewer studies have evaluated aspirations, or the perceived importance of achieving one's goals. In addition, few studies consider how individual traits such as impulsivity affect the degree to which expectations and aspirations motivate or deter delinquent behavior. We contribute to this body of research by evaluating the independent effects of expectations and aspirations, and the aspiration-expectation gap (i.e., strain) on delinquent behavior during the year following an adolescent's first arrest using a large (N = 1117), racially/ethnically diverse sample of male adolescents (46.55% Latino, 35.81% Black, 14.95% White, and 2.69% Other race). In addition, we considered how impulse control interacts with expectations, aspirations, and strain to motivate behavior. Our results indicated that both aspirations, expectations and strain uniquely influence criminal behavior. Importantly, aspirations interacted with impulse control, such that aspirations affected delinquency only among youth with higher impulse control. Our findings suggest that aspirations may only influence behavior if youth also have the psychosocial capabilities to consider their future aspirations when behaving in the present.

Critically ill patients represent a population with multiple risk factors for aspiration. Features such as decreased level of consciousness, mechanical ventilation, and comorbities as stroke, correlate with this increased threat in intensive care unit (ICU) patients. Recognition of deglutition dysfunction may identify patients at high risk of aspiration, and thereby help to avoid pulmonary complications such as recurrent pneumonia. The goal of our report is show a severe case of recurrent aspirative pneumonia after acute stroke and intubation, alerting to appropriate diagnosis and treatment of this condition. A male patient, 57 year old, was admitted to the hospital because of acute stroke. Ten days later, the patient began to have fever and severe shortness of breath. He was admitted to the ICU necessitating of intratracheal intubation. Four days after intubation he was extubated, however, he had a new aspirative pneumonia in ICU, newly treated. An evaluation of swallowing demonstrated a severe deglutition dysfunction with a high risk of aspiration. The patient was transferred, but aspirative pneumonia was diagnosed eight days after his ICU discharge and he was readmitted, stayed for a long time in ICU and presenting severe morbidity. ICU patients who are at risk for swallowing dysfunction and aspiration should be identified to prevent their associated morbidity and mortality.

Fryburg, J.S.; Lin, K.Y.; Golden, W.L.

This report is on a 14-month-old boy with manifestations of Opitz (G/BBB) syndrome in whom a 22q11.2 deletion was found. Deletion analysis was requested because of some findings in this patient reminiscent of velocardiofacial (VCF) syndrome. The extent of aspiration and of respiratory symptoms in this child is not usually seen in VCF syndrome. Opitz syndrome maps to at least two loci, one on Xp, the other on 22q11.2. 12 refs., 2 figs.

Meconium aspiration syndrome (MAS) triggers inflammatory and oxidative pathways which can inactivate both pulmonary surfactant and therapeutically given exogenous surfactant. Glucocorticoid budesonide added to exogenous surfactant can inhibit inflammation and thereby enhance treatment efficacy. Neonatal meconium (25 mg/ml, 4 ml/kg) was administered intratracheally (i.t.) to rabbits. When the MAS model was prepared, animals were treated with budesonide i.t. (Pulmicort, 0.25 mg/kg, M+B); with surfactant lung lavage (Curosurf®, 10 ml/kg, 5 mg phospholipids/ml, M+S) followed by undiluted Curosurf® i.t. (100 mg phospholipids/kg); with combination of budesonide and surfactant (M+S+B); or were untreated (M); or served as controls with saline i.t. instead of meconium (C). Animals were oxygen-ventilated for additional 5 h. Cell counts in the blood and bronchoalveolar lavage fluid (BAL), lung edema formation (wet/dry weight ratio), oxidative damage of lipids/ proteins and inflammatory expression profiles (IL-2, IL-6, IL-13, TNF-alpha) in the lung homogenate and plasma were determined. Combined surfactant+budesonide therapy was the most effective in reduction of neutrophil counts in BAL, oxidative damage, levels and mRNA expression of cytokines in the lung, and lung edema formation compared to untreated animals. Curosurf fortified with budesonide mitigated lung inflammation and oxidative modifications what indicate the perspectives of this treatment combination for MAS therapy.

Cushing's syndrome due to ectopic adrenocorticotropic hormone production from adrenal medullary lesions has occasionally been described. We retrospectively reviewed all 164 cases of Cushing's syndrome and 77 cases of pheochromocytomas during 10 years. Of all cases with Cushing's syndrome, only two cases (1.2 %) were due to ectopic adrenocorticotropic hormone production from adrenal medullary lesions (one case of pheochromocytoma and one case of adrenal medullary hyperplasia). Of all pheochromocytomas only the above-mentioned case (1.3 %) also gave rise to an ectopic adrenocorticotropic hormone syndrome. The clinical presentation of adrenocorticotropic hormone-secreting pheochromocytoma and adrenal medullary hyperplasia can be anything from mild to dramatic. These are rare conditions important to bear in mind in the workup of a patient with Cushing's syndrome or with pheochromocytoma. The identification of ectopic adrenocorticotropic hormone secretion from adrenal medullary lesions can be life-saving.

Patients with resection of stomach and especially with Billroth II reconstruction (gastro jejunal anastomosis), are more likely to develop afferent loop syndrome which is a rare complication. When the afferent part is obstructed, biliary and pancreatic secretions accumulate and cause the distention of this part. In the case of a complete obstruction (rare), there is a high risk developing necrosis and perforation. This complication has been reported once in the literature. A 54-year-old Greek male had undergone a pancreato-duodenectomy (Whipple procedure) one year earlier due to a pancreatic adenocarcinoma. Approximately 10 months after the initial operation, the patient started having episodes of cholangitis (fever, jaundice) and abdominal pain. This condition progressively worsened and the suspicion of local recurrence or stenosis of the biliary-jejunal anastomosis was discussed. A few days before his admission the patient developed signs of septic cholangitis. Our case demonstrates a rare complication with serious clinical manifestation of the afferent loop syndrome. This advanced form of afferent loop syndrome led to the development of huge enterobiliary reflux, which had a serious clinical manifestation as cholangitis and systemic sepsis, due to bacterial overgrowth, which usually present in the afferent loop. The diagnosis is difficult and the interventional radiology gives all the details to support the therapeutic decision making. A variety of factors can contribute to its development including adhesions, kinking and angulation of the loop, stenosis of gastro-jejunal anastomosis and internal herniation. In order to decompress the afferent loop dilatation due to adhesions, a lateral-lateral jejunal anastomosis was performed between the afferent loop and a small bowel loop.

Short stature represents one of the main features of children with Noonan syndrome. The reason for impaired growth remains largely unknown. To assess GH and IGF1 secretion in children with Noonan syndrome. 12 prepubertal children with Noonan syndrome due to mutations in the PTPN11 gene [7 males, 6 females; median age, years: 8.6 (range 5.1-13.4)] were studied; 12 prepubertal children with short stature (SS) [7 males, 5 females; median age, years: 8.1 (range 4.8-13.1)] served as the control group. GH secretion after arginine stimulation test; IGF1 generation test by measurement of IGF1 levels before and after recombinant GH (rGH) administration (0.05 mg/kg/day for 4 days). Baseline and stimulated peak values of GH were not significantly different between the two groups. At +120 minutes, GH levels remained significantly higher (p = 0.0121) in comparison with baseline values in children with Noonan syndrome. Baseline IGFI levels in patients and in SS controls were not significantly different, in contrast to values after the rGH generation test [205 ng/mL (interquartiles 138.2-252.5 ng/mL) and 284.5 ng/mL (interquartiles 172-476 ng/mL), respectively; p = 0.0248]. IGF1 values were significantly related to height (baseline: r = 773, p = 0.0320; peak: r = 0.591, p = 0.0428) in children with Noonan syndrome. Blunted increase of IGF1 after the rGH generation test was present in children with Noonan syndrome due to mutations in the PTPN11 gene in comparison with SS children. This finding may be due to partial GH resistance in the former likely related to altered Ras-MAPK signaling pathway.

Accidental aspiration of kerosene is a common problem among children in developing countries. This descriptive study involved the retrospective analysis of children admitted with kerosene aspiration in a tertiary care hospital in South India for a year. Kerosene aspiration contributed to 60.4% of poisoning cases. Boys aged less than three years and from a rural background formed a significant proportion. Tachypnoea, cough and crepitations were the predominant clinical findings. Male gender and malnutrition (weight for age <80%) were significantly associated with prolonged hospital stay.

Compartment syndrome due to extravasation of peripheral parenteral nutrition: extravasation injury of parenteral nutrition.

Compartment syndrome is a rare but devastating condition that can result in permanent neuromuscular or soft tissue injuries. Extravasation injuries, among the iatrogenic causes of compartment syndrome, occur under a wide variety of circumstances in the inpatient setting. Total parenteral nutrition via a peripheral route is an effective alternative for the management of critically ill children who do not obtain adequate nutrition via the oral route. However, there is an inherent risk of extravasation, which can cause compartment syndrome, especially when detected at a later stage. Herein, we report a rare case of compartment syndrome and skin necrosis due to extravasation, requiring emergency fasciotomy and skin graft in a 7-month-old boy who was treated with peripheral parenteral nutrition via a pressurized infusion pump. Although we cannot estimate the exact time at which extravasation occurred, the extent and degree of the wound suggest that the ischemic insult was prolonged, lasting for several hours. Pediatric clinicians and medical teams should carefully examine the site of insertion of the intravenous catheter, especially in patients receiving parenteral nutrition via a peripheral intravenous catheter with a pressurized infusion pump.

A 67-year-old woman with asthma visited our hospital with increasing dyspnea and new-onset paresthesia and purpura in her legs. Physical examination showed a wheeze, pretibial edema, and surrounding purpura. Chest X-rays showed cardiac decompensation and an electrocardiogram revealed a new ST-T change. Laboratory data showed leukocytosis, hypereosinophilia (10,450/μL), troponin T(+), elevated BNP, and markedly elevated eosinophil cationic protein (ECP) (> 150 ng/mL). Echocardiography revealed diffuse left ventricular hypokinesis (ejection fraction 30%) with increased wall thickness. Coronary angiography was normal. Cardiac magnetic resonance imaging implied diffuse myocardial edema and subendocardial late gadolinium enhancement. Skin biopsy of purpura showed superfi cial perivascular dermatitis with remarkable eosinophilic infiltrations. No evidence of drug allergies, parasitic infection, or myeloproliferative disorder was detected. Based on these findings, a diagnosis of eosinophilic myocarditis due to Churg-Strauss syndrome was considered. She was administered prednisolone at a dose of 1 mg/kg, cyclophosphamide, and diuretics. Several markers of eosinophilic myocarditis and heart failure gradually improved, including ECP. She was discharged 30 days later with no cardiac event. Eosinophilic myocarditis is characterized by predominantly eosinophilic infi ltration. Eosinophilic granule proteins, such as ECP and major basic protein, play important roles in the pathogenesis of eosinophilic myocarditis. We experienced a rare case of eosinophilic myocarditis due to Churg-Strauss syndrome. Markedly elevated ECP played an important role in the early diagnosis and subsequent reduction in ECP served as a marker of monitoring. In an asthmatic patient with dyspnea, hypereosinophilia, and vasculitis, Churg-Strauss syndrome with eosinophilic myocarditis should be considered.

To investigate the frequency, circumstances, demographics and autopsy findings of infants and children dying as a result of foreign body aspiration. Retrospective review of autopsy cases in children aged between seven days and 18 years, at one specialist centre over a 16-year period, in which death was the result of aspiration of a foreign body. Ten cases were identified out of a total autopsy population of 2165. Only one individual had an underlying diagnosis potentially contributing to aspiration. All but one case involved aspiration of food, with grapes being a feature of four cases. In cases with a prolonged survival interval, autopsy demonstrated bronchopneumonia and hypoxic-ischaemic encephalopathy. In the remaining cases autopsy findings were non-specific. Fatal aspiration of a foreign body is rare in this population. The cases involve normal children who aspirate food, particularly grapes. There are typically minimal, non-specific findings at autopsy.

Foreign body aspiration is a pediatric urgency that occurs primarily between 1 and 3 years old. The aim of this paper is to present the symptomatology, clinical and radiological findings, and the therapeutic used in our hospital with patients with foreign body aspiration diagnosis from 1995 until 2011. Patient's age was between 0 and 16 years old. We included 337 patients; where males predominate (205). The medium age was 23 months. The most frequent foreign bodies founded were seeds (192) in 57% and metallic objects in 18.3%. Cough (74.5%), dyspnea (70%), cyanosis (42.4%) and stridor (26%), were the main symptoms. Right bronchus was the most frequent localization (37.7%). In 21% of the patients the reference diagnostic was wrong due to treating it as a respiratory infection. All foreign bodies were extracted by rigid bronchoscopy. No deaths were reported in any proceeding. In our experience, infants are the most affected group, and the primordial symptoms are cough and dyspnea. Organic objects had the highest prevalence of aspiration.

Megaesophagus carries a poor to guarded prognosis due to death from aspiration pneumonia. Options for medical management of regurgitation are limited to strategic oral or gastrostomy tube feeding. To describe the use and efficacy of intermittent esophageal suctioning to prevent regurgitation and associated episodes of aspiration pneumonia in dogs with megaesophagus. Four dogs with acquired idiopathic megaesophagus and recurrent aspiration pneumonia. Retrospective review of medical records of dogs with megaesophagus in which intermittent suctioning of esophageal content was employed for management of recurrent aspiration pneumonia. Intermittent suctioning of the esophagus was initiated in 4 dogs after failure of strict gastrostomy tube feeding failed to prevent regurgitation and repeated episodes of aspiration pneumonia. Suctioning was accomplished by esophagostomy tube in 3 dogs and per os in 1 dog. After initiation of esophageal suctioning, dogs survived for a median of 13.5 additional months (range, 10-30 months) during which time 2 dogs had no additional episodes of aspiration pneumonia and 2 dogs had infrequent episodes of pneumonia, but aspiration was suspected to be a contributing factor in their death. Complications included clogging of the esophagostomy tube, esophagostomy site infections, and esophagitis. Use of intermittent esophageal suctioning in dogs with megaesophagus that continue to regurgitate despite gastrostomy tube feedings can reduce or abolish clinical episodes of aspiration pneumonia.

Parkinson's disease (PD) patients show a high prevalence of swallowing disorders and tracheal aspiration of food. The videofluoroscopic study of swallowing (VFSS) allows clinicians to visualize the visuoperceptual and temporal parameters associated with swallowing disorders in an attempt to predict aspiration risk. However, this subject remains understudied in PD populations. Our aim was to identify the predictors of penetration-aspiration in PD patients using the VFSS. Consecutive patients were evaluated using VFSS with different consistencies and volumes of food. A speech-language pathologist measured the type of intra-oral bolus organization, loss of bolus control, bolus location at the initiation of the pharyngeal swallow, the presence of multiple swallows, piecemeal deglutition, bolus residue in the pharyngeal recesses and temporal measures. Scores ≥3 on the penetration-aspiration scale (PAS) indicated the occurrence of penetration-aspiration. Using logistic marginal regression, we found that residue in the vallecula, residue in the upper esophageal sphincter and piecemeal deglutition were associated with penetration-aspiration (odds ratio (OR) = 4.09, 2.87 and 3.83; P = 0.0040, 0.0071 and 0.0009, respectively). Penetration/aspiration occurred only with fluids (both of thin and thick consistency), and no significant differences were observed between fluid types or food volumes. The mechanisms underlying dysphagia and penetration/aspiration in PD patients and indications for further studies are discussed.

In patients with oropharyngeal and nasopharyngeal bleeding, blood aspiration can make airway management difficult and lead to severe pulmonary complications. A 44-year-old male patient with recurrent epistaxis underwent surgery for hemostasis. The patient aspirated blood through the endotracheal tube when he hiccupped during the surgery. The patient was diagnosed with blood aspiration after intraoperative fiberoptic bronchoscopy revealed a blood clot and viscous mucus in the airways, but no sign of active bleeding. Tracheobronchial suctioning and irrigation with normal saline was performed through the bronchoscope to remove the aspirated blood clot. Prior to emergence from anesthesia, sugammadex was administered to induce complete neuromuscular recovery and enable the patient to cough up any blood remaining in the airways. The patient was successfully extubated and fully recovered with no complications. Blood aspiration due to oropharyngeal or nasopharyngeal bleeding can be diagnosed and treated by tracheobronchial suctioning via fiberoptic bronchoscopy. In addition, sugammadex can enable patients to recover spontaneous breathing, facilitate extubation, and enable patients to cough up any blood remaining in the airways.

Olecranon bursitis might be a minor problem in the outpatient clinic but relatively be common to occur. However, there are few well-designed studies comparing approaches to treatment. (1) Which treatment (compression bandaging with nonsteroidal antiinflammatory drugs [NSAIDs], aspiration, or aspiration with steroid injections) is associated with the highest likelihood of resolution of nonseptic olecranon bursitis? (2) Which treatment is associated with earliest resolution of symptoms? (3) What factors are associated with treatment failure by 4 weeks? We enrolled 133 patients from two centers; after applying prespecified exclusions (septic bursitis or concomitant inflammatory arthritis, intraarticular elbow pathology, recent aspiration or steroid injection done elsewhere, and refusal to participate), 90 patients were randomly allocated to receive compression bandaging with NSAIDs (C), aspiration (A), or aspiration with steroid injection (AS) groups (30 patients in each). The groups were similar at baseline in terms of age and gender. Seven patients (four from Group A and three from Group AS) were lost to followup. All patients were followed up weekly for 4 weeks, and the same treatment procedure was repeated if the bursitis recurred with any substantial fluid collection. At 4 weeks, the state of resolution and pain visual analog scale (VAS) were evaluated. Failed resolution was defined as presence of persistent olecranon bursal fluid collection at Week 4 after the initiation of the treatment; on the contrary, if bursal fluid collection was clinically reduced or completely disappeared by the end of Week 4, the treatment was considered successful. We compared the proportion of resolution by Week 4 and the median times to resolution among the treatment groups. In addition, we evaluated whether the resolution affected pain VAS and what factors were associated with the resolution. There were no differences in the proportion of patients whose bursitis resolved by Week 4

To explore the clinicopathological characteristics of aspiration pneumonia in the elderly. The clinical data of 30 cases of autopsy-proven aspiration pneumonia in Beijing Hospital from 1973 to 2002 were reviewed. The patients consisted of 28 males and 2 females, aged from 63 to 103 [mean (83 ± 9)] years. Only 15 cases were clinically diagnosed as aspiration pneumonia before death. Concomitant diseases were severe and complex, mostly coronary disease, cerebrovascular disease, hypertension, COPD, and diabetes mellitus. All the patients suffered from at least 3 concomitant diseases. Long-term bedridden and nasogastric feeding was seen in 11 and 17 patients respectively. The clinical presentation and chest X-ray of aspiration pneumonia in the elderly were nonspecific and variable. Mixed infections were common . The main bacteria isolated were Gram-negative bacilli, in particular Pseudomonas aeruginosa, Stenotrophomonas maltophilia, Escherichia coli and Candida albicans. By pathology, macrophages with foreign bodies were found in all the 30 cases and multiple small abscesses were found in 14 cases. The lesions were adjacent to the bronchioles and in the lung tissue around the bronchioles, mostly multi-lobar and bilateral. Unilateral or bilateral pleural effusion developed in 20 patients. The accordance between radiological and pathological diagnosis of aspiration pneumonia was very poor. The foci of infection detected by X-ray were proven by autopsy in 13 patients, while pleural effusions in X-ray were proven by autopsy in 15 patients. Multi-concomitant diseases, mixed infection and extra-pulmonary presentations were common in elderly patients with aspiration pneumonia. Multiple small abscesses were the pathological characteristics of aspiration pneumonia in the aged. A definite clinical diagnosis of aspiration pneumonia was difficult. Recurrent silent microaspiration was a feature of aspiration in the elderly. The assessment of risk factor of aspiration played an

Aspiration pneumonia represents an under-reported complication of chemoradiotherapy in patient with head and neck cancer. The objective of the current study was to evaluate the incidence, risk factors, and mortality of aspiration pneumonia in a large cohort of patients with head and neck cancer who received concurrent chemoradiotherapy. Patients who had head and neck cancer diagnosed between 2000 and 2009 were identified from the Surveillance, Epidemiology, and End Results-Medicare database. Aspiration pneumonia was identified from Medicare billing claims. The cumulative incidence, risk factors, and survival after aspiration pneumonia were estimated and compared with a noncancer population. Of 3513 patients with head and neck cancer, 801 developed aspiration pneumonia at a median of 5 months after initiating treatment. The 1-year and 5-year cumulative incidence of aspiration pneumonia was 15.8% and 23.8%, respectively, for patients with head and neck cancer and 3.6% and 8.7%, respectively, for noncancer controls. Among the patients with cancer, multivariate analysis identified independent risk factors (P < .05) for aspiration pneumonia, including hypopharyngeal and nasopharyngeal tumors, male gender, older age, increased comorbidity, no surgery before radiation, and care received at a teaching hospital. Among the patients with cancer who experienced aspiration pneumonia, 674 (84%) were hospitalized; and, of these, 301 (45%) were admitted to an intensive care unit. The 30-day mortality rate after hospitalization for aspiration pneumonia was 32.5%. Aspiration pneumonia was associated with a 42% increased risk of death (hazard ratio, 1.42; P < .001) after controlling for confounders. The current results indicated that nearly 25% of elderly patients will develop aspiration pneumonia within 5 years after receiving chemoradiotherapy for head and neck cancer. A better understanding of mitigating factors will help identify patients who are at risk for this potentially

Occupational aspirations of black South African adolescents.

The present study provides a description of the occupational aspirations of 216 black high school students in a special program by the amount of training required (status) and Holland's 1973 typology as well as by gender, age, socioeconomic status, knowledge of self, and occupational knowledge. Analysis indicates that most adolescents aspire to Social and Investigative occupations, and occupations with a high status. Most of this select sample displayed low self- and occupational knowledge. Aspirations appear unrealistic in terms of trends within the labor market, but might be more realistic with effective and relevant guidance programs in schools.

Conventional cuffed tracheotomy tubes do not prevent aspiration of secretions. Aspiration of saliva may be decreased with the use of a subglottic suction port. Prospective. Shiley Disposable Cuffed Tracheotomy (DCT) tubes sizes 4, 6, and 8 (Tyco Healthcare, Pleasanton, CA) were compared to Portex Blue Line Ultra Suctionaid (BLUS) tracheotomy tubes sizes 6, 7, and 8 (Fig 1; Smiths Medical, Watford, UK). All tubes were tested in a simulated tracheal model using 10 cc of human saliva with no suction, intermittent suction, and constant suction (15 minutes). There was a significant decrease in aspirate between the larger Shiley and BLUS tubes with intermittent suction (mean 8.38 mL Shiley 6 vs 1.60 mL BLUS 7; 8.50 mL Shiley 8 vs 2.80 mL BLUS 8). There was a significant decrease in aspirate between all sizes of Shiley and BLUS tubes with continuous suction. For BLUS 7 and 8, there was a significant difference between intermittent suction (mean, 1.60 mL, 2.80 mL, respectively) and continuous suction (mean, 0.20 mL, 0.60 mL respectively). Shiley and BLUS without suction were equivalent. Subglottic suction tracheotomy tubes reduce the risk of aspiration beyond the cuff in a bench-top model.

Aspiration is an often unrecognized comorbidity in children with Down syndrome with serious medical consequences. This retrospective chart review of swallow study reports characterizes oral and pharyngeal phase dysphagia and diet modifications on videofluoroscopic swallow studies (VFSS) in a large cohort of children with Down syndrome. A total of 158 pediatric patients (male = 95; female = 63; mean age 2.10 years, SD 3.17 years) received an initial VFSS at a pediatric teaching hospital as part of their medical care. A total of 56.3 % (n = 89) children had pharyngeal phase dysphagia with aspiration and deep laryngeal penetration occurring most frequently. Of the 61 patients who aspirated, 90.2 % (n = 55) did so silently with no cough or overt clinical symptoms. In 76.7 % of cases of pharyngeal phase dysphagia, a functional feeding plan, with use of thickened liquids or change in feeding system to control flow rate and/or bolus size, was able to be established, which allowed children to continue eating by mouth. Thickened liquids (76.7 %, n = 46) were the most effective adaptation, with change in feeding system alone effective in only 8.3 % (n = 5) cases. Oral phase dysphagia was reported in the majority of patients (63.8 %, n = 88/138); however, this was not predictive of pharyngeal phase dysphagia. Age, sex, and reason for referral, including prior clinical symptoms, did not have a statistically significant impact on the presence of dysphagia. This comprehensive review has application to clinical understanding and management of dysphagia in children with Down syndrome.

Abstract Rationale: Saccharated ferric oxide has been shown to lead to elevation of fibroblast growth factor 23, hypophosphatemia, and, consequently, osteomalacia. Moreover, mineral imbalance is often observed in patients with short-bowel syndrome to some degree. Patient concerns: A 62-year-old woman with short-bowel syndrome related with multiple resections of small intestines due to Crohn disease received regular intravenous administration of saccharated ferric oxide. Over the course of treatment, she was diagnosed with tetany, which was attributed to hypocalcemia. Additional assessments of the patient revealed not only hypocalcemia, but also hypophosphatemia, hypomagnesemia, osteomalacia, and a high concentration of fibroblast growth factor 23 (314 pg/mL). Diagnoses: We diagnosed her with mineral imbalance-induced osteomalacia due to saccharated ferric oxide and short-bowel syndrome. Interventions: Magnesium replacement therapy and discontinuation of saccharated ferric oxide alone. Outcomes: These treatments were able to normalize her serum mineral levels and increase her bone mineral density. Lessons: This case suggests that adequate evaluation of serum minerals, including phosphate and magnesium, during saccharated ferric oxide administration may be necessary, especially in patients with short-bowel syndrome.

A 26-year-old woman felt tingling on her tongue and itching both in the throat and on the face immediately after she put a cashew nut on her tongue. She had a history of atopic dermatitis and bronchial asthma, but not of pollinosis. CAP-FEIA and skin prick test (SPT) were positive for cashew nuts. The results showed negative for peanuts and other tree nuts than cashew nuts. Consequently, she was diagnosed with oral allergy syndrome due to cashew nuts. In addition, the result of skin prick test with cashew nuts normalized one year after she began avoiding cashew nuts, indicating that cashew nuts allergy would be due to sensitization by itself rather than to cross-reactivity between cashew nuts and pollens in this case.

Riedel thyroiditis is a rare fibrosing disorder characterized by extension of the fibroinflammatory process beyond the thyroid capsule. Due to the nature of this lesion, fine-needle aspiration often yields scant material and may be interpreted as non-diagnostic. In this report, we describe cytologic features that allow the cytopathologist to favor a diagnosis of Riedel thyroiditis, thereby guiding appropriate further work-up and management. © 2015 Wiley Periodicals, Inc.

Cardiac involvement in eosinophilia is potentially fatal and requires early diagnosis and prompt treatment. We report here the case of a 71-year-old female patient with eosinophilia>10,000/mm(3) for 2 months due to a myeloproliferative/myelodysplastic syndrome, with a rapidly progressive exertional dyspnea explained by an important circumferential eosinophilic pericarditis. Due to a rapid evolution to a tamponade, an emergent surgical drainage was performed. Subsequent medical treatment combined high-dose corticosteroids (1mg/kg/day) with hydroxyurea and imatinib. The outcome was favourable with regression of the effusion, of the volume overload symptoms and decrease in eosinophilia. Copyright © 2015 Elsevier Masson SAS. All rights reserved.

Adult respiratory distress syndrome due to fat embolism in the postoperative period following liposuction and fat grafting.

Fat embolism is defined as mechanical blockage of the vascular lumen by circulating fat globules. Although it primarily affects the lungs, it can also affect the central nervous system, retina, and skin. Fat embolism syndrome is a dysfunction of these organs caused by fat emboli. The most common causes of fat embolism and fat embolism syndrome are long bone fractures, although there are reports of its occurrence after cosmetic procedures. The diagnosis is made clinically, and treatment is still restricted to support measures. We report the case of a female patient who developed adult respiratory distress syndrome due to fat embolism in the postoperative period following liposuction and fat grafting. In this case, the patient responded well to alveolar recruitment maneuvers and protective mechanical ventilation. In addition, we present an epidemiological and pathophysiological analysis of fat embolism syndrome after cosmetic procedures.

Pulmonary aspiration of gastric contents during routine endoscopy

DOE Office of Scientific and Technical Information (OSTI.GOV)

La France, N.D.; Cole, P.; Wolfe, E.

Radioactive tracer studies are a sensitive means to detect occult pulmonary aspiration of gastric contents. A complication of diagnostic endoscopy is aspiration of contents even in fasted patients. The authors have studied 21 hospitalized patients who underwent elective endoscopy (END) for suspected UGI pathology. Fifteen minutes before END, and prior to pharygeal anesthesia, 1 mCi Tc-99m-sulfur colloid, added to the usual 30cc of simethicone routinely administered before END, was given orally. END was performed as usual and 2 hours later anterior 100,000 count images of the chest were obtained. All the studies were interpreted without history or clinical information. Fevermore » developed within 24 hours (and septic shock in 1) in both patients with positive studies while no fever occurred in the remaining patients with negative studies (rho<.001). The authors conclude that oral radionuclide pulmonary aspiration studies may; detect aspiration not recognized by the endoscopist, reveal evidence of aspiration that preceeds adverse clinical signs and symptoms, and be influenced by systemic pre-END drugs known to affect GI secretions and motility.« less

1999-06-01

We report a case of Angelman syndrome (AS) with paternal uniparental disomy (pUPD) of chromosome 15. This 6-year-old girl with overgrowth had frequent, but only provoked laughter, was mildly ataxic with limb hypertonia, and had no intelligible speech. She had deep-set eyes, protruding tongue, and prominent chin. The karyotype was normal. DNA analysis with microsatellites from chromosome 15 showed no inheritance of maternal alleles both within and outside the AS critical region. Proximal markers showed reduction to homozygosity of paternal alleles, intermediate markers showed nonreduction, and distal markers reduction, thus suggesting a meiosis II nondisjunction event in the father with two crossovers. This is, to our knowledge, the first reported case of AS due to meiosis II nondisjunction. We present detailed physical measurements in this patient, adding to the clinical description of the milder phenotype in AS due to pUPD.

Aspiration and sclerotherapy versus hydrocoelectomy for treating hydrocoeles.

Hydrocoeles are common cystic scrotal abnormalities, described as a fluid-filled collection between the visceral and parietal layers of the tunica vaginalis of the scrotum. There are two approaches for treatment of hydrocoeles: surgical open hydrocoelectomy and aspiration followed by sclerotherapy.  We compared the benefits and harms of aspiration and sclerotherapy versus hydrocoelectomy for the management of hydrocoeles. We searched the Cochrane Renal Group's Specialised Register to 2 August 2014 through contact with the Trials' Search Co-ordinator using search terms relevant to this review. Randomised controlled trials (RCTs) and quasi-RCTs comparing aspiration and sclerotherapy versus hydrocoelectomy for the management of hydrocoeles. Two authors independently extracted data and assessed risk of bias in the included studies. Random effects meta-analyses were performed using relative risk (RR) for dichotomous outcomes and mean differences (MD) for continuous outcomes, with 95% confidence intervals (CI). We found four small studies that met the inclusion criteria. These studies enrolled 275 patients with 282 hydroceles. Participants were randomised to aspiration and sclerotherapy (155 patients with 159 hydroceles) and surgery (120 patients with 123 hydroceles). All studies were assessed as having low or unclear risk of bias for selection bias, detection bias, attrition bias and selective reporting bias. Blinding was not possible for participants and investigators based on the type of interventions. Blinding for statisticians was not reported in any of included studies.There were no significant difference in clinical cure between the two groups (3 studies, 215 participants: RR 0.45, 95% CI 0.18 to 1.10), however there was significant heterogeneity (I² = 95%). On further investigation one study contributed all of the heterogeneity. This could be due to the agent used or perhaps due to the fact that this is a much older study than the other two studies included in

Piriformis ganglion: An uncommon cause of sciatica.

Sciatica can occur due to a spinal lesion, intrapelvic tumor, diabetic neuropathy, and rarely piriformis syndrome. The causes of piriformis syndrome vary by a space-occupying lesion. A ganglionic cyst can occur in various lesions in the body but seldom around the hip joint. In addition, sciatica due to a ganglionic cyst around the hip joint has been reported in one patient in Korea who underwent surgical treatment. We experienced two cases of sciatica from a piriformis ganglionic cyst and we report the clinical characterics and progress after non-operative treatment by ultrasonography-guided aspiration. The two cases were diagnosed by magnetic resonance imaging and were treated by ultrasonography-guided aspiration. We followed the patients for more than 6months. The symptoms of piriformis syndrome from the ganglion improved following aspiration and this conservative treatment is a treatment method that can be used without extensive incision or cyst excision.

2013-07-01

Trigeminal neuralgia (TN) is a common pain in the orofacial region. Dandy-Walker syndrome (DWS) is a congenital malformation of the cerebellar and the fourth ventricle foramina atresia. Dandy-Walker syndrome is rarely found in patients with TN. This article presents a 36-year-old man with the symptoms of typical TN. His physical examination was entirely normal. An enhanced magnetic resonance imaging was taken. Magnetic resonance imaging revealed the bilateral lateral ventricle, the fourth and third ventricle significantly enlarged with severe obstructive hydrocephalus, a huge posterior fossa cyst connected with the fourth ventricle, and hypoplastic vermis. The pain was controlled by Tegretol. The reported case suggests that DWS is an unusual cause of TN.

Although women who highly identify with other women are more susceptible to stereotype threat effects, women's identification might associate with greater leadership aspirations contingent on (1) counter-stereotype salience and (2) feminist identification. When gender counter-stereotypes are salient, women's identification should associate with greater leadership aspiration regardless of feminism, while when gender stereotypes are salient, women's identification would predict greater leadership aspirations contingent on a high level of feminist identification. In our study US-based women ( N = 208) attended to gender stereotypic (vs. counter-stereotypic) content. We measured identification with women and identification with feminism, and, following the manipulation, leadership aspirations in an imagined work scenario. The interaction between identification with women, identification with feminism, and attention to stereotypes (vs. counter-stereotypes) significantly predicted leadership aspirations. In the counter-stereotypic condition women's identification associated with greater leadership aspirations regardless of feminist identification. In the stereotypic condition women's identification predicted leadership aspirations only at high levels of feminist identification. We conclude that salient counter-stereotypes and a strong identification with feminism may help high women identifiers increase their leadership aspirations.

Children frequently present for suspected foreign body aspiration, many have mild symptoms and/or negative radiographs raising the question of a radiolucent foreign body aspiration. Retrospective review of patients having bronchoscopy for suspected radiolucent foreign body aspiration from 2000 to 2010 collecting demographics, history, hospital presentation, radiographic, and operative details. Pearson's correlation was used between event history, presentation, radiographic details and bronchoscopically identified foreign body with P value <0.01. 138 patients, mean age 2.6 years, mean weight 15.6 kg, 68% male. Event symptoms: 81% witnessed events, 64% wheezing, 43% coughing, 39% choking, 6% stridor, and 0.7% lethargy. Hospital presentation: 70% persistent symptoms, wheezing 56%, coughing 15%, desaturations 11%, stridor 7%, choking 4%, and lethargy 1%. 92% of patients had a chest x-ray; air trapping found in 38%, and lung collapse in 21%. 2 patients received CT scans; 1 had lung collapse. Bronchoscopy identified foreign bodies in 93% of patients: food 68%, plastic 18%, non-descript 11%, rocks 3%. No correlations between event symptoms, hospital presentation, radiographs and foreign body presence. Event history, hospital presentation, and radiographs are insufficient in proving the absence of a radiolucent foreign body. Patients with suspected radiolucent foreign body aspiration should undergo diagnostic bronchoscopy prior to discharge. Copyright © 2013 Elsevier Inc. All rights reserved.

Aspiration dynamics of multi-player games in finite populations

Du, Jinming; Wu, Bin; Altrock, Philipp M.; Wang, Long

2014-01-01

On studying strategy update rules in the framework of evolutionary game theory, one can differentiate between imitation processes and aspiration-driven dynamics. In the former case, individuals imitate the strategy of a more successful peer. In the latter case, individuals adjust their strategies based on a comparison of their pay-offs from the evolutionary game to a value they aspire, called the level of aspiration. Unlike imitation processes of pairwise comparison, aspiration-driven updates do not require additional information about the strategic environment and can thus be interpreted as being more spontaneous. Recent work has mainly focused on understanding how aspiration dynamics alter the evolutionary outcome in structured populations. However, the baseline case for understanding strategy selection is the well-mixed population case, which is still lacking sufficient understanding. We explore how aspiration-driven strategy-update dynamics under imperfect rationality influence the average abundance of a strategy in multi-player evolutionary games with two strategies. We analytically derive a condition under which a strategy is more abundant than the other in the weak selection limiting case. This approach has a long-standing history in evolutionary games and is mostly applied for its mathematical approachability. Hence, we also explore strong selection numerically, which shows that our weak selection condition is a robust predictor of the average abundance of a strategy. The condition turns out to differ from that of a wide class of imitation dynamics, as long as the game is not dyadic. Therefore, a strategy favoured under imitation dynamics can be disfavoured under aspiration dynamics. This does not require any population structure, and thus highlights the intrinsic difference between imitation and aspiration dynamics. PMID:24598208

Burton, E M; Brick, W G; Hall, J D; Riggs, W; Houston, C S

1996-02-01

In this retrospective study, we reviewed the demographic and radiographic findings of 155 children with bronchoscopy-proven tracheobronchial foreign body aspiration (FBA). Two thirds of the patients were male, and most were children between 1 and 2 years of age. An aspirated peanut accounted for one third of all cases. Foreign body location was distributed nearly evenly to the right and left primary bronchi; tracheal foreign body was noted in 16 patients. The most frequent symptoms of FBA were cough (85 patients) and wheezing (60 patients). Although most patients were seen within 1 day of aspiration, 30 patients had symptoms that lasted at least 1 week before diagnosis. The most common radiographic findings were unilateral or segmental hyperlucency (59) or atelectasis (38). The trachea was the site of the foreign body in one half of children with a normal chest radiograph and FBA.

Oguzkurt, Levent, E-mail: loguzkurt@yahoo.com; Ozkan, Ugur; Demirturk, Orhan S.

Purpose: Our purpose was to report the outcome of endovascular treatment with manual aspiration thrombectomy as the first-line thromboablative method for phlegmasia cerulea dolens. Methods: Between October 2006 and May 2010, seven consecutive patients (5 women, 2 men; age range, 31-80 years) with the diagnosis of phlegmasia cerulea dolens secondary to acute iliofemoral deep venous thrombosis had endovascular treatment with manual aspiration thrombectomy. Catheter-directed thrombolysis and stent placement were used as adjunctive procedures. Phlegmasia was left-sided in five and right-sided in two patients. Results: All patients had associated great saphenous vein thrombosis in addition to iliofemoral deep vein thrombosis (DVT).more » Aspiration thrombectomy completely removed the thrombus from the popliteal vein to the inferior vena cava (IVC) in all cases. Three patients with May-Thurner syndrome had stent placement in the left common iliac vein. Two patients had early recurrences. Repeated aspiration thrombectomy was unsuccessful in one patient. There were no complications related to the procedure. One patient who had been successfully treated died of sepsis and another patient who had unsuccessful repeated interventions had below-the-knee amputation. Overall, the clinical success and survival rates of patients in this study were 86%. On follow-up, three patients with successful treatment were asymptomatic with no deep venous insufficiency. One of these patients died during the 4-month follow-up period. Two patients had mild ankle swelling with deep venous insufficiency. Conclusions: Manual aspiration thrombectomy with adjunctive use of catheter-directed thrombolysis and stent placement is an effective endovascular treatment method with high clinical success and survival rates for phlegmasia cerulean dolens.« less

Commodity aspirations in Easterlin's relative income theory of fertility.

PubMed

Ahlburg, D A

1984-01-01

This paper presents the preference ordering that underlies Easterlin's relative income theory of fertility. Commodity aspirations are a key component of the theory and the paper explores how the introduction of commodity aspirations into the utility function affects the consumption of commodities and bearing of children. The formation and empirical specification of commodity aspirations are also discussed. Commodity aspirations are formed by the material environment experienced during childhood and are primarily a function of parental income. Easterlin, Leibenstein and Ben-Porath argus that it is the parental consumption or standard of living that determines the child's testes or aspirations. It is the parents' spending on themseleves rather than total parental income that can be used as a proxy for the child's commodity aspirations. Bagozzi and Van Loo identify 4 significant contributions made by Easterlinhs theory of fertility. They cite his stress on potential income flow through time as being pertinent to household decision making; tastes being an explicit determinant of fertility; background charactersticis and norms as to standards of child care and family size affecting fertility indirectly through tastes rather than directly; and the fact that relative income has an effect on fertility in addition to the influence of the absolute level of income. The number of children demanded is a negative function of commodity aspirations, as is the utility of the family. Studies of the demand for commodities and children should include data on parental resources.

2013-12-01

A 1-year-old sexually intact male Korat cat was referred for ophthalmological consultation due to anisocoria. Mydriasis with external ophthalmoplegia and absence of pupillary light responses in the right eye and nasofacial hypalgesia were seen. Cavernous sinus syndrome (CSS) was suspected. Bilateral deformities of the jaw and phalangeal bones, severe spinal pain and abnormal conformation of the lumbar spine were also present. Radiographic examination revealed several mineralised masses in the appendicular and axial skeleton, indicative of multiple cartilaginous exostoses. For further investigation of the CSS-related neurological deficits, the cat underwent computed tomography (CT) examination of the skull. CT images revealed a non-vascularised, calcified, amorphous mass originating from the right lateral skull base and superimposing on the sella turcica. Based on the severity of diffuse lesions and owing to the clinical signs of extreme pain, the cat was euthanased. A diffuse skeletal and intracranial osteochondromatosis was diagnosed histologically.

A 6-year-old, castrated male ferret (Mustela putorius furo) was presented with progressive neurological signs consisting of a right-sided head tilt and ataxia. Neurological examination revealed hemiparesis and absence of proprioception on the right side, consistent with central vestibular syndrome. Measurement of blood glucose excluded hypoglycemia due to insulinoma. Contrast-enhanced computed tomography revealed the presence of an intracranial mass, consistent with either granuloma or neoplasia. Palliative treatment with prednisolone yielded no improvement. At postmortem examination, a final diagnosis of a choroid plexus papilloma originating from the fourth ventricle was made. This is the first report of such a tumor in a ferret.

In Germany Puumala virus (PUUV), known to cause mild forms of hemorrhagic fever with renal syndrome (HFRS), is the predominating endemic hantavirus. We herein describe an unusually severe case of a PUUV infection that occurred in summer 2015 in South Eastern Germany in a region known to be endemic for PUUV since over ten years. A 54-year-old female gardener was admitted to hospital with fever, cough and dyspnea. Within 48hours the patient developed a rapid progressive adult respiratory distress syndrome (ARDS) with circulatory failure and required ECMO (extracorporeal membrane oxygenation) treatment. Serological and molecular biological examinations of serum samples confirmed an infection with PUUV. Partial sequences of the S- and M-segment clustered to a strain previously described in South Eastern Germany. Our reported case highlights, that in rare incidents PUUV can cause hantavirus cardiopulmonary syndrome, a syndrome that is usually found after infections with New World hantaviruses, and neurological symptoms.

Leigh syndrome can result from both nuclear and mitochondrial DNA defects. Mutations in complex V genes of the respiratory chain were considered until recently as the most frequent cause for mitochondrial inherited Leigh syndrome, while gene defects in complex I were related to recessive Leigh syndrome. Recently few reports of mutations in the mitochondrial-encoded complex I subunit genes causing Leigh syndrome have been reported. We describe a 1-month-old baby who acutely deteriorated, with abrupt onset of brainstem dysfunction, due to basal ganglia lesions extending to the brainstem. A muscle biopsy demonstrated complex I deficiency. Subsequent analysis of the mitochondrial genome revealed a homoplastic T10191C mutation in the ND3 gene (in blood and muscle), resulting in a substitution of serine to proline. Hair root analysis revealed a 50% mutant load, reflecting heteroplasmy in early embryonic stages. The mutation was also detected in his mother (5%). Western blot analysis revealed a decrease of the 20 kDa subunit (likely ND6) and of the 30 kDa subunit (NDUFA9), which is probably due to instability attributed to the inability to form subcomplexes with ND3. This is the first description of infantile Leigh syndrome due to a maternally transmitted T10191C substitution in ND3 and not due to a de novo mutation. This mutation is age and tissue dependent and therefore may not be amenable to prenatal testing.

To aspirate breast abscess through a wide bore (14-gauge) intravenous (I/V) cannula and determine its efficacy in terms of the number of recurrences and number of aspirations. Case series. Dow University of Health Sciences and Civil Hospital and Bantva Hospital, Karachi, Pakistan, from January 2009 to December 2011. Patients with breast abscesses confirmed on ultrasound without skin ulceration were selected. The soft area of breast abscess with positive fluctuation was marked and fixed with index finger and thumb. A 14-gauge cannula was inserted. Pus was aspirated through a 50 cc syringe, repeated till no aspirate could be obtained. All patients were followed weekly for 4 weeks, clinically for size of lump, local tenderness and temperature, while complete resolution was confirmed on ultrasound, as resolution of the lesion. A total of 55 patients were included in this study. Mean age was 29 ± 5.58 years while ranging from 20 - 40 years. Complete resolution of abscess was seen in 31 (56.4%) cases by single aspiration. Second aspiration was required in 24 (43.6%) patients and third aspiration in single setting was required in one case only. Recurrence after the second aspiration occurred in 08 (14.5%). Incision drainage was required in 7 (12.7%) patients. Percutaneous aspiration of breast abscess through a wide bore (14-gauge) I/V cannula is a simple alternative to incision and drainage.

Thyroid Swelling and Thyroiditis in the Setting of Recent hCG Injections and Fine Needle Aspiration

PubMed Central

Lamos, Elizabeth M.; Munir, Kashif M.

2016-01-01

A 60-year-old woman presented with a neck mass and underwent fine needle aspiration of a left thyroid nodule. During this time, she had been injected with hCG for weight loss. Soon after, she developed rapid diffuse thyroid growth with pain. She was ultimately diagnosed with thyrotoxicosis due to postaspiration subacute thyroiditis and subsequently became hypothyroid. This condition is rare in the nonpregnant state in noncystic nodules with a smaller needle gauge approach. The incidence of thyroid nodule discovery and evaluation is increasing. As more procedures are undertaken, understanding of potential complications is important. This case highlights potential complications of thyroid fine needle aspiration including diffuse thyroid swelling and thyroiditis. The role of hCG injections is speculated to have potentially stimulated thyroid follicular epithelium via cross-reactivity with the TSH receptor and contributed to the acute inflammatory response after fine needle aspiration.

Aspiration lung disorders in bovines: a case report and review.

PubMed

Shakespeare, Anthony S

2012-11-01

Lung aspiration disorders in bovines are invariably diagnosed as infectious aspiration pneumonias. There is a distinct differentiation between aspiration pneumonia and aspiration pneumonitis in humans that can be applied to bovines. The nature and quantity of the aspirate can result in differing pathogeneses which can require differing therapeutic approaches. Whilst blood gases were important in detecting and prognosticating lung problems, changes in barometric pressure with altitude have to be considered when interpreting partial pressures of oxygen. Anatomical differences in the lungs of bovines can explain why this species is more prone to certain pneumonic problems. Pulmonary physiotherapy is important in treating lung disorders in humans and should be considered as an adjunct therapy in bovine respiratory conditions. A case work-up was used to highlight some of the points discussed in this article.

Capsule endoscopy (CE) has an excellent safety profile. Although retention is the most cited complication, capsule aspiration is less frequent and is often reported only as isolated cases. This study represents a systematic effort to compile and scrutinize the available data on capsule aspiration to provide comprehensive and conclusive information on this CE complication. A systematic literature search was performed in PubMed, Embase and Chinese National Knowledge Infrastructure. The search terms used were 'capsule endoscopy' AND 'aspiration' (both terms searched as keyword and MeSH). We included case reports and/or series on capsule aspiration, as well as observational cohort studies that reported capsule aspiration among their complications/outcomes. Thirty-four case reports with 37 cases of capsule aspiration were identified. A further four observational studies reported aspiration as part of a cohort of patients undergoing CE. 94.6% of aspirations occurred in elderly men. 87.1% had significant comorbidities. 59.5% had symptoms on aspiration, with cough reported most frequently. The most common location of aspiration was the right main bronchus. Half of the patients required intervention for capsule retrieval; bronchoscopy was the most common management, with good effect. There was a single fatality following capsule aspiration, not directly related to the procedure, and one case of aspiration pneumonia. Outcomes were good for all other patients. The estimated overall aspiration rate is 0.1%. Although very rare and generally safely managed, capsule aspiration should be anticipated in certain patient groups and capsule administration should be approached with necessary precautions.

Ingested and Aspirated Foreign Bodies.

PubMed

Green, S Sarah

2015-10-01

Esophageal and aspirated foreign bodies have important clinical significance, and both should be considered carefully when the history or physical examination findings raise sufficient suspicion. The published evidence regarding the diagnosis and management of foreign body ingestion or aspiration is weighted disproportionately with observational studies, case controls, expert opinion, and systematic reviews. Most of the publications would receive a categorization of C (observational studies including case-control and cohort design) and D (expert opinion, case reports, and clinical reasoning). One of the few prospective studies examining the diagnostic evaluation of foreign body aspiration in children could be considered level B evidence (randomized clinical trials, systematic reviews, or diagnostic studies with minor limitations). This study found that the medical history is the most important predictive part of the evaluation. There is evidence for considering bronchoscopy if there is significant history suggestive of foreign body aspiration, even in the setting of normal physical examination findings. (28). Most ingested foreign bodies spontaneously pass without incident. However, special attention should be paid to objects in the esophagus as well as to batteries and magnets. Based on a systematic review of the literature (level B evidence) and the potential for rapid and life-threatening damage, batteries in the esophagus should be removed immediately. (10) Other objects, such as coins, may be observed for passage in an asymptomatic patient. In addition, given the high risk of significant complications, ingestion of high-powered magnets should be quickly and carefully evaluated. Although single magnets are likely to pass without complication, multiple magnets or magnets ingested with other metal objects can cause significant damage and should be removed if there is any concern for mural entrapment, bowel perforation, or failure to progress.

Context: Hutchinson-Gilford progeria syndrome (HGPS) and mandibuloacral dysplasia are well-recognized allelic autosomal dominant and recessive progeroid disorders, respectively, due to mutations in lamin A/C (LMNA) gene. Heterozygous LMNA mutations have also been reported in a small number of patients with a less well-characterized atypical progeroid syndrome (APS). Objective: The objective of the study was to investigate the underlying genetic and molecular basis of the phenotype of patients presenting with APS. Results: We report 11 patients with APS from nine families, many with novel heterozygous missense LMNA mutations, such as, P4R, E111K, D136H, E159K, and C588R. These and previously reported patients now reveal a spectrum of clinical features including progeroid manifestations such as short stature, beaked nose, premature graying, partial alopecia, high-pitched voice, skin atrophy over the hands and feet, partial and generalized lipodystrophy with metabolic complications, and skeletal anomalies such as mandibular hypoplasia and mild acroosteolysis. Skin fibroblasts from these patients when assessed for lamin A/C expression using epifluorescence microscopy revealed variable nuclear morphological abnormalities similar to those observed in patients with HGPS. However, these nuclear abnormalities in APS patients could not be rescued with 48 h treatment with farnesyl transferase inhibitors, geranylgeranyl transferase inhibitors or trichostatin-A, a histone deacetylase inhibitor. Immunoblots of cell lysates from fibroblasts did not reveal prelamin A accumulation in any of these patients. Conclusions: APS patients have a few overlapping but some distinct clinical features as compared with HGPS and mandibuloacral dysplasia. The pathogenesis of clinical manifestations in APS patients seems not to be related to accumulation of mutant farnesylated prelamin A. PMID:19875478

The Budd-Chiari syndrome (BCS) is a rare disorder due to chronic liver disease (CLD), which is caused by the obstruction of hepatic venous outflow that can be located at any place from the small hepatic venules up to the entrance of the inferior vena cava (IVC) into the right atrium. Among the causes of BCS, the rarer one is coagulation factor deficiencies. Here, we report a case of BCS associated with deficiency of protein C resulting in thrombus in IVC. The patient was a 50-year-old male, who had been suffering from recurrent abdominal and leg swelling for a long period of 7 years. He was evaluated thoroughly, and other causes of liver cirrhosis were excluded. Begum R, Al Mahtab M, Al Mamun A, Moben AL, Hossain SMS, Das DC, Malakar D, Rashid HO, Roy PP, Rahman S.

Ectopic production of corticotropin-releasing hormone (CRH) by a pheochromocytoma is an infrequent cause of Cushing's syndrome. We report the case of a 43-year-old man with Cushing's syndrome due to a CRH-producing adrenal pheochromocytoma. The patient had clinical and biochemical evidence of hypercortisolism in conjunction with high ACTH levels and non-suppressible serum cortisol levels on low-dose and high-dose dexamethasone suppression testing. In addition to these clinical features of one month's duration, the patient developed symptoms of pheochromocytoma including headache, hypertension that was resistant to conventional therapy and excessive sweating. Biochemical testing confirmed elevated 24-hour urinary catecholamines and metabolites. Abdominal CT revealed a 4.5 x 4 x 3.5 cm mass in the left adrenal gland. He underwent elective left adrenalectomy. Light microscopic and immunochemical studies revealed a pheochromocytoma that contained immunoreactive CRH and was negative for ACTH. Plasma ACTH and dexamethasone supression tests normalized after surgery. This is an unusual case of a CRH-secreting pheochromocytoma. This was complicated by renal infarction, illustrating further the complexity of Cushing's syndrome in a patient with pheochromocytoma caused by CRH hypersecretion.

Leigh syndrome (LS) is a rare disease mainly affecting the central nervous system due to the abnormalities of mitochondrial energy generation and seen in early childhood with progressive loss of movement, mental abilities, seizures, nystagmus, ophthalmoparesis, optic atrophy, ataxia, dystonia, or respiratory failure. Anesthesia and surgery exacerbate the risks of aspiration, wheezing, and breathing difficulties. Tracheal irritability can be stimulated with the efforts of intubation. We report the anesthetic management of a rare case of an 11-year-old boy with a severe form of LS for percutaneous endoscopic gastrostomy insertion. The patient was closely monitored during the procedure and the postoperative period. Carefully chosen anesthetic agents, good pain control, and close monitoring are essential. PMID:29628597

Keeping Up with the Joneses: Friends' Perfectionism and Students' Orientation Toward Extrinsic Aspirations.

Kasser and Ryan (1993,1996) have contrasted two types of life values: intrinsic aspirations, which include community contribution, building close relationships, and self-growth, and extrinsic aspirations, which include fame, wealth, and physical beauty. Prioritization of extrinsic relative to intrinsic aspirations has been related cross-sectionally to decreased well-being (Kasser, 2002). However, the influence of close others in the etiology of young adults' prioritization of extrinsic aspirations, and the prospective effects of aspirations on well-being, are not well understood. In a multiple-informant prospective study of 341 university students (mean age = 19.4; 64% Caucasian; 74% female), we examined the influence of friends' and family members' perfectionism on participants' aspirations, and the outcomes of prioritization of extrinsic aspirations. Having friends high in other-oriented perfectionism was significantly positively related to prioritization of extrinsic over intrinsic aspirations. Furthermore, living with friends amplified the effect. Last, prioritization of extrinsic aspirations at T1 was related to decreased subjective well-being and self-concordance for goals 3 months later. The study provides preliminary evidence for a relationship between friends' other-oriented perfectionism and students' orientation toward extrinsic aspirations, as well as negative prospective consequences of students' orientation to extrinsic aspirations. © 2015 Wiley Periodicals, Inc.

Limitation of the Cavitron technique by conifer pit aspiration.

PubMed

Beikircher, B; Ameglio, T; Cochard, H; Mayr, S

2010-07-01

The Cavitron technique facilitates time and material saving for vulnerability analysis. The use of rotors with small diameters leads to high water pressure gradients (DeltaP) across samples, which may cause pit aspiration in conifers. In this study, the effect of pit aspiration on Cavitron measurements was analysed and a modified 'conifer method' was tested which avoids critical (i.e. pit aspiration inducing) DeltaP. Four conifer species were used (Juniperus communis, Picea abies, Pinus sylvestris, and Larix decidua) for vulnerability analysis based on the standard Cavitron technique and the conifer method. In addition, DeltaP thresholds for pit aspiration were determined and water extraction curves were constructed. Vulnerability curves obtained with the standard method showed generally a less negative P for the induction of embolism than curves of the conifer method. Differences were species-specific with the smallest effects in Juniperus. Larix showed the most pronounced shifts in P(50) (pressure at 50% loss of conductivity) between the standard (-1.5 MPa) and the conifer (-3.5 MPa) methods. Pit aspiration occurred at the lowest DeltaP in Larix and at the highest in Juniperus. Accordingly, at a spinning velocity inducing P(50), DeltaP caused only a 4% loss of conductivity induced by pit aspiration in Juniperus, but about 60% in Larix. Water extraction curves were similar to vulnerability curves indicating that spinning itself did not affect pits. Conifer pit aspiration can have major influences on Cavitron measurements and lead to an overestimation of vulnerability thresholds when a small rotor is used. Thus, the conifer method presented here enables correct vulnerability analysis by avoiding artificial conductivity losses.

A 52-year-old Asian male with no traditional risk factors for coronary artery disease presented with acute coronary syndrome. Coronary angiography showed complete thrombotic occlusion of the left circumflex with a large thrombus burden in the setting of diffuse aneurysmal enlargement of the coronary arteries consistent with antecedent Kawasaki disease. Manual thrombectomy with adjunctive intracoronary tirofiban was performed utilizing the GuideLiner catheter ® (Vascular Solutions, Inc., MN, USA). Stent implantation was deferred. Follow-up imaging 48 h later showed preserved coronary flow and decreased thrombus burden. The GuideLiner catheter, a monorail guiding device, served a novel role in thrombus aspiration and intracoronary medication delivery.

AIMS: To assess the feasibility of training nurse practitioners to perform bone marrow aspiration and trephine biopsy, and to compare the quality of these samples with those obtained by medical staff. METHODS: A retrospective audit was undertaken of nurse practitioner and medical staff performance in bone marrow procedures in a busy haematology day unit. RESULTS: Nurse practitioners fared favourably in comparison with medical staff in performing bone marrow trephine biopsies, with mean biopsy lengths of 11 mm and 10.7 mm respectively. However, only 78% of the smears obtained by the nurses were judged technically satisfactory, compared with 91% prepared by doctors. This discrepancy was thought to be due largely to the quality of slide spreading. CONCLUSIONS: With motivated staff and a structured educational and training programme it is possible for nurse practitioners to perform the techniques of bone marrow aspiration and biopsy, and obtain specimens of satisfactory quality, thus improving efficiency of the haematology day unit and increasing quality of patient care.

Medical doctor and engineer are highly esteemed STEM professions. This study investigates academic and motivational characteristics of a sample of high school students in Thailand who aspire to become medical doctors or engineers. We used logistic regression to compare maths performance, gender typicality, gender contentedness, and maths and physics self-concepts among students with aspirations for these two professions. We found that high levels of felt gender contentedness in men had positive association with aspirations for engineering irrespective of the levels of maths or physics self-concept. We found that high levels of felt gender contentedness combined with high levels of maths or physics self-concept in women had positive associations with aspirations to become a medical doctor. These findings are evidence that student views of self are associated with uneven gendered patterns in career aspirations and have implications for the potential for future participation.

Meconium aspiration syndrome (MAS), a common cause of respiratory failure in neonates, is associated with high mortality and morbidity. The objectives of this review were to evaluate the effects of administration of (a) surfactant—either as lung lavage (SLL) or bolus surfactant (BS) and (b) antibiotics on mortality and severe morbidities in neonates with MAS. We searched the following databases: MEDLINE via PubMed, Cochrane CENTRAL, WHOLIS and CABI using sensitive search strategies. We included eight studies on use of surfactant and three studies on use of antibiotics. Neither SLL nor BS reduced the risk of mortality in neonates with MAS (relative risk (RR) 0.38, 95% confidence interval (CI) 0.09 to 1.57; and RR 0.80, 95% CI 0.39 to 1.66, respectively). Both SLL and BS reduced the duration of hospital stay (mean difference −2.0, 95% CI −3.66 to −0.34; and RR −4.68, 95% CI −7.11 to −2.24 days, respectively) and duration of mechanical ventilation (mean difference −1.31, 95% CI −1.91 to −0.72; and mean difference 5.4, 95% CI −9.76 to −1.03 days). Neonates who received BS needed extracorporeal membrane oxygenation (ECMO) less often than the controls (RR 0.64, 95% CI 0.46 to 0.91). Use of antibiotics for MAS did not result in significant reduction in the risk of mortality, sepsis or duration of hospital stay. Surfactant administration either as SLL or BS for MAS was found to reduce the duration of mechanical ventilation and hospital stay; BS also reduced the need for ECMO. Administration of antibiotics did not show any significant clinical benefits in neonates with MAS and no evidence of sepsis. Given the limited number of studies and small number of neonates enrolled, there is an urgent need to generate more evidence on the efficacy and cost-effectiveness of these two treatment modalities before recommending them in routine clinical practice.

2013-01-01

Drawing on a recent national survey of rural high school students, this study investigated the relationship between social capital and educational aspirations of rural youth. Results showed that various process features of family and school social capital were important to predict rural youth's educational aspirations beyond sociodemographic background. In particular, parents' and teachers' educational expectations for their child and student respectively were positively related to educational aspirations of rural youth. In addition, discussion with parents about college was positively related to educational aspirations of rural youth. On the other hand, there was little evidence to suggest that number of siblings and school proportions of students on free lunch and minority students are related to educational aspirations of rural youth, after controlling for the other variables. The authors highlight unique features of rural families, schools, and communities that may combine to explain the complexity of the role of social capital in shaping educational aspirations of rural youth.

Recurrent Fever of Unknown Origin (FUO) Due to Periodic Fever, Aphthous Stomatititis, Pharyngitis and Adenitis (FAPA) Syndrome in an Adult.

PubMed

Muñoz-Gómez, Sigridh; Cunha, Burke A

2013-08-19

FAPA syndrome (periodic fever, aphthous stomatititis, pharyngitis and adenitis) is a relatively new entity described in pediatric patients. In adults, reports of FAPA are limited to rare case reports. The differential diagnosis of FAPA in adults includes Behcet's syndrome, familial Mediterranean fever (FMF), Hyper IgD syndrome and juvenile rheumatoid arthritis (JRA), i.e., adult Still's disease. With FAPA syndrome, between episodes patients are completely asymptomatic and serologic inflammatory markers such as erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) and white blood cell (WBC) count are normal. The etiology of FAFA is unknown, but lack of secondary cases or clustering in close contacts, lack of seasonality, and the lack of progression for years argue against an infectious etiology. We describe an extremely rare case of an adult with a recurrent FUO with profuse night sweats and prominent chills due to FAPA syndrome.

Chin tuck has been has been widely used to prevent aspiration in the patients with dysphagia. This study was performed to investigate the effectiveness and the degree of optimal neck flexion of chin tuck. Ninety-seven patients who showed aspiration in the videofluoroscopic swallow study (VFSS). Participants were grouped into the effective (patients who showed effect with chin tuck) and ineffective group (those who did not show effect with chin tuck). VFSS was performed in neutral and chin tuck position and findings were compared between the groups. Severity of aspiration was assessed by the point penetration-aspiration scale. Duration of dysphagic symptoms, history of tracheostomy, and other possible contributing factors were also compared. Neck flexion angle was measured to find appropriate posture in which aspiration was prevented with chin tuck. Aspiration was reduced or eliminated in only 19 patients (19.6 %) with chin tuck. Oral transit time, pharyngeal delayed time and pharyngeal transit time were significantly shortened in both groups (p < 0.05), but the difference between the groups was not significant. Female sex and absence of residue in pyriform sinus favored the effect of chin tuck (p < 0.05). At least 17.5° of neck flexion was required to achieve an effect with chin tuck. The effectiveness of chin tuck was less than anticipated. Patients without residue in pyriform sinus were more likely to benefit from chin tuck. Sufficient neck flexion was important in chin tuck to prevent aspiration.

Saccharated ferric oxide has been shown to lead to elevation of fibroblast growth factor 23, hypophosphatemia, and, consequently, osteomalacia. Moreover, mineral imbalance is often observed in patients with short-bowel syndrome to some degree. A 62-year-old woman with short-bowel syndrome related with multiple resections of small intestines due to Crohn disease received regular intravenous administration of saccharated ferric oxide. Over the course of treatment, she was diagnosed with tetany, which was attributed to hypocalcemia. Additional assessments of the patient revealed not only hypocalcemia, but also hypophosphatemia, hypomagnesemia, osteomalacia, and a high concentration of fibroblast growth factor 23 (314 pg/mL). We diagnosed her with mineral imbalance-induced osteomalacia due to saccharated ferric oxide and short-bowel syndrome. Magnesium replacement therapy and discontinuation of saccharated ferric oxide alone. These treatments were able to normalize her serum mineral levels and increase her bone mineral density. This case suggests that adequate evaluation of serum minerals, including phosphate and magnesium, during saccharated ferric oxide administration may be necessary, especially in patients with short-bowel syndrome.

To report the first recognized case of Cushing's syndrome due to a corticotropin-releasing hormone (CRH)-secreting ganglioneuroblastoma, which was found in an 18-month-old boy with hypertensive encephalopathy. The clinical, biochemical, and immunohistochemical characteristics of this rare syndrome are described, and the relevant literature is reviewed. An 18-month-old boy with a history of recent weight gain was admitted because of sudden onset of right fixed esotropia and left facial palsy after episodes of emesis. Magnetic resonance imaging showed old left frontal lobe and right hypothalamic infarcts. The patient had generalized obesity, decelerated linear growth, hypertrichosis, hypertension (144/103 mm Hg), hypokalemia, and proteinuria. The 24-hour urinary excretion of free cortisol, catecholamines, and metanephrines was increased. The serum cortisol concentration after a 1-mg overnight dexamethasone suppression test (DST) was 53.7 mg/dL (normal, <5). The serum adrenocorticotropic hormone (ACTH) concentration was 7 pg/mL (normal, 10 to 60), and the CRH level was 439 pg/mL (normal, 24 to 40). An overnight high-dose DST (8 mg) failed to suppress serum cortisol; however, both cortisol and ACTH were responsive to ovine CRH stimulation. Despite discordant dynamic endocrine testing and negative somatostatin receptor scintigraphy, computed tomography showed a right 3.6- by 3.0-cm extra-adrenal retroperitoneal mass with central calcification extending 7 cm cephalocaudally. The patient underwent exploratory laparotomy, followed by chemotherapy. Findings on light microscopic and immunohistochemical examination of the retroperitoneal mass were consistent with a ganglioneuroblastoma that expressed CRH, pro-opiomelanocortin, and ACTH. The evaluation of Cushing's syndrome is one of the most complex endocrine challenges. In this case, it was due to ectopic production of CRH by a ganglioneuroblastoma. Because most CRH-producing tumors also secrete ACTH, the ectopic production

Behcet's disease is a multisystemic vasculitis of unknown etiology with a chronic relapsing course. Vasculitis in Behcet's disease with predominant vascular involvement is the only vasculitis that affects both arteries and veins of any size. Involvement of the renal artery and inferior vena cava is rare among the arteries and veins, respectively. When disease affect the veins, it is in the form of thrombosis. Arterial complications include aneurysms, stenosis and occlusions. Both rupture of arterial aneurysm and occlusion of suprahepatic veins, causing Budd-Chiari syndrome, are associated with a high mortality rate. Vascular involvement is more common in male patients than in female patients. Men and patients with a younger age of onset present with a more severe prognosis. In this case report, we describe a very rare cause of intrarenal arterial aneurysm's rupture with previous Budd-Chiari syndrome due to Behcet's disease and successful angiographic embolization of actively bleeding aneurysm.

Parents' educational aspirations for youth play an important role in shaping youth's own educational aspirations; however, little is known about how and in what context parents may transmit their aspirations to youth effectively. This is of particular interest and import to be examined in Chinese families, given Chinese cultural emphasis on educational achievement and Chinese youth's outstanding academic performance internationally. By integrating several key theories of motivation and parental socialization (i.e., the expectancy-value model of academic achievement, the two-step model of value transmission, the contextual model of parenting, and the self-determination theory), the current study investigated simultaneously the mediating roles of parental involvement in youth's learning and youth's perceptions of parental aspirations, as well as the moderating role of parental warmth in the intergenerational transmission process of educational aspirations in Chinese families. A two-wave longitudinal study spanning about half a year was conducted among 323 Chinese seventh graders (54% female; M age  = 13.25 years) and one of their parents (median educational attainment = completion of high school, median monthly income = USD 766-1226). It was found that parental educational aspirations for youth were related positively both indirectly through parental involvement and directly to youth's perceptions of parental aspirations, which in turn were associated positively with youth's own educational aspirations about half a year later. It was also found that parental educational aspirations for youth and youth's own educational aspirations were associated positively with each other only when youth reported experiencing high levels of parental warmth, but unrelated when youth reported experiencing low levels of parental warmth, whereas such moderating effects of parental warmth were absent on the links from parental aspirations to youth's perceptions of parental

To evaluate the utility of kidney aspiration cytology in the sequential monitorization of acute rejection in renal transplant patients. Thirty patients were submitted to 376 aspirations. The clinical diagnoses were independently established. The representativity of the samples reached 82.7%. The total corrected increment index and the number of immunoactivated cells were higher during acute rejection as compared to normal allograft function, acute tubular necrosis, and cyclosporine nephrotoxicity. The parameters to the diagnosis of acute rejection were sensitivity: 71.8%, specificity: 87.3%, positive predictive value: 50.9%, negative predictive value: 94.9% and accuracy 84.9%. The false positive results were mainly related to cytomegalovirus infection or to the administration of OKT3. In 10 out of 11 false negative results incipient immunoactivation was present alerting to the possibility of acute rejection. Kidney aspiration cytology is a useful tool for the sequential monitorization of acute rejection in renal transplant patients. The best results are reached when the results of aspiration cytology are analyzed with the clinical data.

A 62-year-old man with well-controlled diabetes mellitus developed numbness of the bilateral feet and hands, followed by subacutely progressive weakness and amyotrophy of extremities. He became bed-ridden state, and dyspnea also appeared, so he was referred to our hospital. Physical examination revealed a lean man, with dark-reddish skin pigmentation, crabbed fingers, bilateral pretibial pitting edema, and bristles in extremities. Thoracoabdominal paradoxical respiration was observed and pulmonary vesicular sounds was decreased markedly in the both lungs. Laboratory data revealed hypoproteinemia, abnormalities of endocrine system, but M-protein was not detected. Serum vascular endothelial growth factor level was quite high. Chest radiography revealed elevation of the bilateral diaphragm, the % vital capacity (%VC) was 24%, and arterial blood gas analysis showed marked hypoxia with hypercapnia. These findings suggested that his respiratory failure was induced by bilateral diaphragmatic paralysis caused by bilateral phrenic nerve palsy due to Crow-Fukase syndrome. He became somnolent because of hypercapnic narcosis, so non-invasive positive pressure ventilation (NIPPV) was started. We treated him with intravenous immunoglobulin and oral corticosteroids therapies, and after these therapies, his symptoms were remarkably recovered and NIPPV became unnecessary soon. The most frequent causes of respiratory failure in Crow-Fukase syndrome are pleural effusion and pulmonary hypertension, and only two cases of this syndrome with respiratory failure caused by bilateral diaphragmatic paralysis were reported until now. When the patients with Crow-Fukase syndrome complain of dyspnea, we should take the diaphragmatic paralysis into consideration, which may be improved by appropriate therapies.

Intrinsic aspirations and personal meaning across adulthood: conceptual interrelations and age/sex differences.

PubMed

Morgan, Jessica; Robinson, Oliver

2013-05-01

The present study examined adult age and sex differences in self-reported aspirations and personal meaning. Young, midlife, and older adults (N = 2,557) from the United Kingdom or United States completed an online survey of their aspiration striving, aspiration importance, and personal meaning (subscales of Purposeful Life, Exciting Life, Accomplished Life, Principled Life, Valued Life). Predictions were made in line with humanistic and gerontology theories, which suggest that sources of personal meaning consolidate across the life span toward intrinsically motivated pursuits. Findings supported these predictions, showing that although there was a tendency for aspirations to decline with age, the proportion of intrinsically motivated aspirations increased, as did total meaning and the interrelationship between meaning and intrinsic aspirations. There were also gender differences in personal meaning and aspirations, which suggested a more pronounced midlife dip in intrinsic and purposive goal striving for men, and a greater focus on intrinsic aspirations in women. Developmental and cohort interpretations of these findings and directions for further research are discussed.

Soto's syndrome is a genetic disorder caused by mutations in the NSD1 gene. It is characterized by excessive growth in early life. It features craniofacial abnormalities, developmental delay, hypotonia and advanced bone age. A review of the current literature reveals only chronic otitis media and conductive hearing loss as otolaryngologic manifestations of Soto's syndrome. Our objective was to determine if there are additional manifestations relevant to the otolaryngologist. We performed a retrospective case series in which the Department of Defense electronic medical record was searched for ICD 9 code 253.0 (acromegaly/gigantism). Records were reviewed for genetic testing indicative of Soto's syndrome. These records were further analyzed for evidence of otolaryngologic problems. Seventeen patients were identified with five having confirmed NSD1 mutations consistent with Soto's syndrome. Of these, 4/5 had otolaryngologic problems such as conductive hearing loss, aspiration, laryngomalacia, obstructive sleep apnea and sensorineural hearing loss. Currently there is no description in the literature of these additional manifestations of Soto's syndrome. We present this case series to support the idea that an otolaryngologist should be involved in the multidisciplinary care required for these patients. Published by Elsevier Ireland Ltd.

Perry syndrome is a rare form of autosomal dominant parkinsonism with respiratory failiure recently defined as being due to mutations in the DCTN1 gene. We describe a new family carrying a G71R mutation in the DCTN1 gene. The proband displayed a series of distinctive features not previously described in Perry syndrome: a disorder of vertical downward saccades accompanied by progressive midbrain atrophy, predominant non-motor symptoms responsive to L-DOPA, distinctive cranio-cervical L-DOPA induced dyskinesias, and a good response to high dose L-DOPA therapy and respiratory support. The family was initially thought to have autosomal dominant behavioural variant frontotemporal dementia with parkinsonism. This report expands the clinical definition of this distinctive syndrome.

The Angelman syndrome (AS) is a neurological disorder characterized by severe mental retardation, absent speech, seizures, gait disturbances, and a typical age-dependent facial phenotype. Most cases are due to an interstitial deletion on the maternally inherited chromosome 15, in the critical region q11-q13. Rare cases also result from paternal uniparental disomy of chromosome 15. In a group of 14 patients with sporadic AS diagnosed in Switzerland, we found 2 unrelated females with paternal isodisomy for the entire chromosome 15. Their phenotypes were milder than usually seen in this syndrome: one girl did not show the typical AS facial changes; bothmore » patients had late-onset mild seizures; as they grow older, they had largely undisturbed gross motor functions, in particular no severe ataxia. Both girls were born to older fathers (45 and 43 years old, respectively). The apparent association of a relatively milder phenotype in AS with paternal uniparental disomy will have to be confirmed by detailed clinical descriptions of further patients. 25 refs., 2 figs., 1 tab.« less

Recurrent Fever of Unknown Origin (FUO) Due to Periodic Fever, Aphthous Stomatititis, Pharyngitis and Adenitis (FAPA) Syndrome in an Adult

2013-01-01

FAPA syndrome (periodic fever, aphthous stomatititis, pharyngitis and adenitis) is a relatively new entity described in pediatric patients. In adults, reports of FAPA are limited to rare case reports. The differential diagnosis of FAPA in adults includes Behcet’s syndrome, familial Mediterranean fever (FMF), Hyper IgD syndrome and juvenile rheumatoid arthritis (JRA), i.e., adult Still’s disease. With FAPA syndrome, between episodes patients are completely asymptomatic and serologic inflammatory markers such as erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) and white blood cell (WBC) count are normal. The etiology of FAFA is unknown, but lack of secondary cases or clustering in close contacts, lack of seasonality, and the lack of progression for years argue against an infectious etiology. We describe an extremely rare case of an adult with a recurrent FUO with profuse night sweats and prominent chills due to FAPA syndrome. PMID:26237061

Students' lack of interest in studying science and in science-related careers is a concern in the UK and worldwide. Yet there is limited data, particularly longitudinal, on the sources and development of science-related aspirations. In response, the ASPIRES (Science Aspirations and Career Choice: Age 10-14) longitudinal study is investigating the development of students' educational and occupational aspirations over time. In the first phase of the project, a questionnaire exploring science-related aspirations and interests was completed by over 9,000 primary school students across England. This survey allowed us to explore possible associations between attitudes and aspirations, links which have not been investigated in previous attitudinal studies of this scope. Overall, students expressed positive attitudes to science, reported positive parental attitudes to science and held very positive images of scientists. Multilevel modelling analyses revealed that aspirations in science were most strongly related to parental attitudes to science, attitudes to school science and self-concept in science, and are also associated with students' gender, ethnicity and cultural capital. However, the images students held of scientists were not as closely related to aspirations. These factors are discussed in more detail within the paper, alongside a consideration of possible school-related effects.

Aspiration and sclerotherapy of hydroceles have been considered an effective outpatient procedure. We report on our experience with modification of this procedure in the treatment of 28 hydroceles. A 10 per cent solution of tetracycline hydrochloride was used as the sclerosant. In this series the mean followup was 15 months and there was an over-all 93 per cent success rate. A single treatment was successful in 75 per cent of the hydroceles. Complications included a hematoma in 2 patients and epididymitis in 1. We consider aspiration and sclerotherapy of hydroceles to be a reasonable alternative to an operation.

Due to the solar radiation effect, current air temperature sensors inside a thermometer screen or radiation shield may produce measurement errors that are 0.8 °C or higher. To improve the observation accuracy, an aspirated temperature measurement platform is designed. A computational fluid dynamics (CFD) method is implemented to analyze and calculate the radiation error of the aspirated temperature measurement platform under various environmental conditions. Then, a radiation error correction equation is obtained by fitting the CFD results using a genetic algorithm (GA) method. In order to verify the performance of the temperature sensor, the aspirated temperature measurement platform, temperature sensors with a naturally ventilated radiation shield, and a thermometer screen are characterized in the same environment to conduct the intercomparison. The average radiation errors of the sensors in the naturally ventilated radiation shield and the thermometer screen are 0.44 °C and 0.25 °C, respectively. In contrast, the radiation error of the aspirated temperature measurement platform is as low as 0.05 °C. This aspirated temperature sensor allows the radiation error to be reduced by approximately 88.6% compared to the naturally ventilated radiation shield, and allows the error to be reduced by a percentage of approximately 80% compared to the thermometer screen. The mean absolute error and root mean square error between the correction equation and experimental results are 0.032 °C and 0.036 °C, respectively, which demonstrates the accuracy of the CFD and GA methods proposed in this research.

Despite the low incidence of brain abscesses in Western nations (1-2%), the incidence in developing countries is as high as 8%. We evaluate a minimally invasive image-guided keyhole aspiration of cerebral abscesses and compare it with a series of cases treated with surgical excision. 23 patients (20 male and 3 female, aged 7-67 years) underwent image-guided burr hole aspiration of single or multiple cerebral abscesses. Patient characteristics, perioperative, and postoperative data were analyzed and compared with a second group of 22 patients (14 male and 8 female, aged 12-72) treated for cerebral abscesses with open surgical excision. In all cases, the surgical procedure was performed successfully without complication. 8 of the 23 aspiration cases were performed with the aid of iMRI. A comparison of patient demographics, duration of hospital stay, duration of antibiotic therapy, postoperative neurological recovery time, intraoperative blood loss, operative duration, length of incision, postoperative fever, repeat surgery, and mortality was performed between the aspiration and excision groups. Intraoperative blood loss, operative duration, length of incision, and postoperative fever were all significantly reduced in the aspiration group. Though, duration of hospital stay and antibiotic therapy and postoperative neurological recovery time were all increased in the aspiration group, and statistical significance was observed in all except the duration of hospital stay. This technique is a feasible and comparable minimally invasive alternative to open surgical excision and may provide reduced intraoperative blood loss, shortened operative duration, improved cosmetic outcomes, and a lessened incidence of postoperative fever.

Cowden syndrome is characterized by hamartomatous polyps, trichilemmomas, increased risk of developing neoplasms, and is associated with germline mutations in the PTEN gene. We searched for germline mutations in PTEN in a 49-year-old female patient who presented trichilemmoma with previous history of breast carcinoma, and thyroidectomy for a thyroid nodule. We also searched for somatic mutations in breast and thyroid tumoral tissues. DNA was extracted from peripheral leukocytes, paraffin samples of breast carcinoma, and cytological smears of thyroid nodule fine-needle aspiration biopsy, whose final histopathological diagnosis was adenomatous goiter. PTEN was amplified and sequenced. We identified a novel mutation, due to a T>A inversion at position 159 and A>T inversion at position 160, leading to valine-to-aspartic acid substitution at position 53. The p.Val53Asp was also found in homozygous state in samples obtained from adenocarcinoma breast and thyroid biopsy, denoting loss of heterozygosity. Here, we demonstrated a novel germline mutation in PTEN, as well as somatic loss of the wild-type PTEN allele in breast and thyroid tumors in a patient with Cowden syndrome.

Drug-induced hypersensitivity syndrome (DIHS)/drug rash with eosinophilia and systemic symptoms (DRESS) syndrome is characterized by late disease onset, fever, rash, hepatic dysfunction, haematological abnormalities, lymphadenopathy and often, human herpesvirus (HHV) reactivation. The diagnosis of DIHS is based on the combined presence of these findings. Anticonvulsants are a major cause of DIHS and may also cause Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN). We examined whether SJS/TEN due to anticonvulsants display similar clinical and laboratory features seen in DIHS. Patients diagnosed with SJS or TEN due to anticonvulsants (n = 8) were examined and their clinical features and laboratory findings were compared with patients with anticonvulsant-related DIHS (n = 6). Seven of the eight patients with SJS/TEN developed symptoms > 3 weeks after starting anticonvulsants. Hepatic dysfunction was present in six patients with SJS/TEN and five patients with DIHS. Leucocytosis and/or eosinophilia was noted in seven patients with SJS/TEN and four patients with DIHS. Only one patient in the SJS/TEN group had atypical lymphocytosis; this was present in four patients with DIHS. Reactivation of HHV-6 was detected in one of the four patients tested in the SJS/TEN group, although it was seen in five of the six patients with DIHS. TSJS/TEN due to anticonvulsants may exhibit some clinical and laboratory features of DIHS. The nature of the cutaneous involvement should be emphasized in the diagnosis of DIHS. © 2009 The Author(s).

To study the clinical efficacy of porcine pulmonary surfactant (PS) combined with budesonide suspension intratracheal instillation in the treatment of neonatal meconium aspiration syndrome (MAS). Seventy neonates with MAS were enrolled for a prospective study. The neonates were randomly assigned to PS alone treatment group and PS+budesonide treatment group (n=35 each). The PS alone treatment group was given PS (100 mg/kg) by intratracheal instillation. The treatment group was given budesonide suspension (0.25 mg/kg) combined with PS (100 mg/kg). The rate of repeated use of PS in the PS+ budesonide group was significantly lower than that in the PS alone group 12 hours after treatment (p<0.05). The improvement of PaO 2 /FiO 2 , TcSaO 2 , PaO 2 , and PaCO 2 in the PS+ budesonide group was significantly greater than that in the PS alone group 6, 12, and 24 hours after treatment (p<0.05). The chest X-ray examination showed that the pulmonary inflammation absorption in the PS+ budesonide group was significantly better than that in the PS alone group 48 hours after treatment (p<0.05). The incidence of complications in the PS+budesonide group was significantly lower than that in the PS alone group (p<0.05), and the average hospitalization duration was significantly shorter than that in the PS alone group (p<0.01). PS combined with budesonide suspension intratracheal instillation for the treatment of neonatal MAS is effective and superior to PS alone treatment.

Capsule endoscope aspiration into the respiratory tract is a rare complication of capsule endoscopy. Despite the potential seriousness of this complication, no accepted methods exist to accurately predict and therefore prevent it. We describe the case of an 85-year-old male who presented for evaluation of iron deficiency anemia. He complained of dysphagia while ingesting a patency capsule, with several attempts over a period of 5 min before he was successful. Five days later, he underwent capsule endoscopy, where he experienced similar symptoms in swallowing the capsule. The rest of the examination proceeded uneventfully. On reviewing the captured images, the capsule endoscope was revealed to be aspirated, remaining in the respiratory tract for approximately 220 s before images of the esophagus and stomach appeared. To our knowledge, this is the first documented case of a patient who experienced capsule endoscope aspiration after ingestion of a patency capsule. This case suggests that repeated attempts required for ingesting the patency capsule can predict capsule endoscope aspiration. We presume that paying sufficient attention to the symptoms of a patient who ingests a patency capsule could help us prevent serious complications such as aspiration of the capsule endoscope. In addition, this experience implies the potential risk for ingesting the patency capsule. We must be aware that the patency capsule could also be aspirated and there may be more unrecognized aspiration cases. PMID:26600772

We must be aware that the patency capsule could also be aspirated and there may be more unrecognized aspiration cases.

Forty patients with suspected malignant disease of the liver underwent percutaneous fine-needle aspiration biopsy with radioisotope scintigraphic and fluoroscopic guidance. The needle was aimed at focal defects identified on the liver scan and several passes were made. When the scan was diffusely abnormal, the liver was widely sampled with multiple passes. Thirty patients were eventually considered to have malignant disease and aspiration biopsy was positive in 28 (93%) of these patients, including 25 of 26 with liver metastases (96%). There were two false-positive results and one minor complication. In 24 patients, conventional wide-bore needle biopsy was also performed. In thismore » group, 16 patients had a final diagnosis of hepatic malignancy. Aspiration biopsies were positive in 14 of these (87%) and conventional needle biopsies were positive in four (25%). Guided percutaneous fine-needle aspiration biopsy is recommended for pathologic diagnosis of hepatic malignancy because of its simplicity, high yield, and reasonable safety.« less

Infrared Thermal Imaging During Ultrasonic Aspiration of Bone

NASA Astrophysics Data System (ADS)

Cotter, D. J.; Woodworth, G.; Gupta, S. V.; Manandhar, P.; Schwartz, T. H.

Ultrasonic surgical aspirator tips target removal of bone in approaches to tumors or aneurysms. Low profile angled tips provide increased visualization and safety in many high risk surgical situations that commonly were approached using a high speed rotary drill. Utilization of the ultrasonic aspirator for bone removal raised questions about relative amount of local and transmitted heat energy. In the sphenoid wing of a cadaver section, ultrasonic bone aspiration yielded lower thermal rise in precision bone removal than rotary mechanical drills, with maximum temperature of 31 °C versus 69 °C for fluted and 79 °C for diamond drill bits. Mean ultrasonic fragmentation power was about 8 Watts. Statistical studies using tenacious porcine cranium yielded mean power levels of about 4.5 Watts to 11 Watts and mean temperature of less than 41.1 °C. Excessively loading the tip yielded momentary higher power; however, mean thermal rise was less than 8 °C with bone removal starting at near body temperature of about 37 °C. Precision bone removal and thermal management were possible with conditions tested for ultrasonic bone aspiration.

National efforts to compare hospital outcomes for patients with pneumonia may be biased by hospital differences in diagnosis and coding of aspiration pneumonia, a condition that has traditionally been excluded from pneumonia outcome measures. To evaluate the rationale and impact of including patients with aspiration pneumonia in hospital mortality and readmission measures. Using Medicare fee-for-service claims for patients 65 years and older from July 2012 to June 2015, we characterized the proportion of hospitals' patients with pneumonia diagnosed with aspiration pneumonia, calculated hospital-specific risk-standardized rates of 30-day mortality and readmission for patients with pneumonia, analyzed the association between aspiration pneumonia coding frequency and these rates, and recalculated these rates including patients with aspiration pneumonia. A total of 1,101,892 patients from 4,263 hospitals were included in the mortality measure analysis, including 192,814 with aspiration pneumonia. The median proportion of hospitals' patients with pneumonia diagnosed with aspiration pneumonia was 13.6% (10th-90th percentile, 4.2-26%). Hospitals with a higher proportion of patients with aspiration pneumonia had lower risk-standardized mortality rates in the traditional pneumonia measure (12.0% in the lowest coding and 11.0% in the highest coding quintiles) and were far more likely to be categorized as performing better than the national mortality rate; expanding the measure to include patients with aspiration pneumonia attenuated the association between aspiration pneumonia coding rate and hospital mortality. These findings were less pronounced for hospital readmission rates. Expanding the pneumonia cohorts to include patients with a principal diagnosis of aspiration pneumonia can overcome bias related to variation in hospital coding.

Autosomal dominant Carvajal plus syndrome due to the novel desmoplakin mutation c.1678A > T (p.Ile560Phe).

Carvajal syndrome is an autosomal dominant or autosomal recessive disorder, manifesting with dilated cardiomyopathy, woolly hair, and palmoplantar keratoma. Additional manifestations can be occasionally found. Carvajal syndrome may be due to mutations in the desmocollin-2, desmoplakin, or plakophilin-2 gene. We report a family with Carvajal syndrome which additionally presented with hypoacusis, noncompaction, recurrent pharyngeal infections, oligodontia, and recurrent diarrhoea. Father and brother were also affected and had died suddenly, the father despite implantation of a cardioverter defibrillator (ICD). Genetic studies revealed the novel pathogenic mutation c.1678A > T in the desmoplakin gene resulting in the amino acid change Ile to Phe at position 560 in the index case and her brother. The index case underwent ICD implantation recently. Phenotypic manifestations of Carvajal syndrome are even broader than so far anticipated, the number of mutations in the desmoplakin gene responsible for Carvajal syndrome is still increasing, and these patients require implantation of an ICD as soon as their diagnosis is established.

To investigate clinical characteristics and changes of pulmonary imaging of mineral oil aspiration pneumonia in children. The clinical features, CT findings, and effects of corticosteroid therapy were analyzed in 16 children with mineral oil aspiration pneumonia, who were hospitalized in our hospital from January 2003 to July 2013. All patients with mineral oil aspiration pneumonia had a history of mineral oil administration.Four patients had no clinical manifestations. Ten cases presented fever, and 8 of the 10 patients had fever in 4-8 h after taking mineral oil, and the temperature was between 39-40 °C. There were wheezing in 2 cases, shortness of breath in 6 cases, cyanosis in 1 case, dyspnea in 3 cases, and moaning in 2 cases, chest pain in 1 case, headache and abnormal EEG in 1 case.Six patients had rales in lungs. Peripheral blood white cells increased in 10 cases, and C- reactive protein elevated in 7 patients. Chest CT examination showed abnormal findings in 6 children, and the earliest CT was performed within 2 h after the accident. The rest 10 children got chest X-ray, and 9 of 10 children had abnormal findings. The earliest X-ray was done within 3 h after the accident. And the remaining 1 of 10 children showed no significant changes in the first chest X-ray 2-3 h after the accident until 3 days. All of the patients received corticosteroid and antibiotic treatments, 4 cases underwent bronchoalveolar lavage, 3 patients were given albumin, 6 cases received intravenous immunoglobulin. Three cases delayed in treatment with hormone because of misdiagnosis, and 2 of them had clearly secondary infections. Twelve patients recovered completely from oil aspiration pneumonia after 8 days to 5.5 months. Oil aspiration pneumonia in children occurs in almost all cases after mineral oil aspiration. Pulmonary opacities can be found by chest CT in most patients within 24 hours after mineral oil aspiration. Corticosteroids therapy was effective for patients with

Decreased Cough Sensitivity and Aspiration in Parkinson Disease

PubMed Central

Brandimore, Alexandra E.; Okun, Michael S.; Davenport, Paul W.; Hegland, Karen W.

2014-01-01

BACKGROUND: Aspiration pneumonia is a leading cause of death in people with Parkinson disease (PD). The pathogenesis of these infections is largely attributed to the presence of dysphagia with silent aspiration or aspiration without an appropriate cough response. The goal of this study was to test reflex cough thresholds and associated urge-to-cough (UTC) ratings in participants with PD with and without dysphagia. METHODS: Twenty participants with PD were recruited for this study. They completed a capsaicin challenge with three randomized blocks of 0, 50, 100, and 200 μM capsaicin and rated their UTC by modified Borg scale. The concentration of capsaicin that elicited a two-cough response, total number of coughs, and sensitivity of the participant to the cough stimulus (UTC) were measured. The dysphagia severity of participants with PD was identified with the penetration-aspiration scale. RESULTS: Most participants with PD did not have a consistent two-cough response to 200 μM capsaicin. UTC ratings and total number of coughs produced at 200 μM capsaicin were significantly influenced by dysphagia severity but not by general PD severity, age, or disease duration. Increasing levels of dysphagia severity resulted in significantly blunted cough sensitivity (UTC). CONCLUSIONS: UTC ratings may be important in understanding the mechanism underlying morbidity related to aspiration pneumonia in people with PD and dysphagia. Further understanding of decreased UTC in people with PD and dysphagia will be essential for the development of strategies and treatments to address airway protection deficits in this population.

Life goals, or aspirations, organize and direct behavior over extended periods of time. The present study, guided by self-determination theory, examined the consequences of pursuing and attaining aspirations over a one-year period in a post-college sample. Results indicated that placing importance on either intrinsic or extrinsic aspirations related positively to attainment of those goals. Yet, whereas attainment of intrinsic aspirations related positively to psychological health, attainment of extrinsic aspirations did not; indeed, attainment of extrinsic aspirations related positively to indicators of ill-being. Also as predicted, the association between change in attainment of intrinsic aspirations and change in psychological health was mediated by change in the satisfaction of the basic psychological needs for autonomy, competence, and relatedness. Discussion focuses on the idea that not all goal attainment is beneficial; rather, attainment of aspirations with different contents relates differentially to psychological health. PMID:20161160

Malignant tumours in the apices of the lungs, especially bronchogenic carcinoma (Pancoast tumours), are the most common cause of Pancoast' syndrome which presents with shoulder or arm pain radiating along the medial aspect of forearm and weakness of small muscles of hand with wasting of hypothenar eminence due to neoplastic involvement of C8 and T1 and T2 nerve roots of brachial plexus. There are a number of benign conditions which may lead to Pancoast's syndrome; fungal abscess located in the apex of lung is one of them. Oral or intravenous antifungals are the treatment of choice in this case and complete recovery is usual, whereas, surgical resection followed by chemoradiotherapy is the treatment of choice in case of Pancoast's syndrome due to lung cancers. Hence, tissue diagnosis is mandatory. Here, we report a case of apical fungal abscess causing Pancoast's syndrome in an immunocompetent individual of 35 years of age to raise the awareness among the clinicians regarding this rare clinical entity.

Stroke is the most common neurological disease in adults that is associated with deglutition disorders. The presence of laryngeal sensitivity is very important in developing safe swallowing without risk of pulmonary complications. The aim of this study was to correlate laryngeal sensitivity with laryngeal penetration and tracheal aspiration after swallows of three food consistencies (puree, thickened liquid, and liquid) in poststroke individuals in the late phase. A cross-sectional clinical study was performed with 91 post-ischemic stroke individuals, with oropharyngeal dysphagia, who were in rehabilitation center treatment from 2009 to 2011. They had a mean age of 68.1 years and average time since injury was 22.6 months; 39 had injury to the right hemisphere and 52 had injury to the left hemisphere. All underwent fiberoptic endoscopic evaluation of swallowing and evaluation of laryngeal sensitivity by touching the tip of the endoscope to the arytenoids and aryepiglottic folds. The linear correlation coefficient of Spearman was applied to evaluate the correlation between laryngeal penetration and tracheal aspiration and the presence/absence of laryngeal sensitivity. There was a negative correlation between the observation of penetration and tracheal aspiration and laryngeal sensitivity, with all bolus consistencies (p < 0.001 for aspiration and p ≤ 0.01 for penetration). The absence of laryngeal sensitivity determines the more frequent findings of penetration and tracheal aspiration. This sensory stimulus in the mucosa of the pharynx and larynx is an essential element for safe swallowing and its deficiency associated with altered motor activity can cause laryngeal penetration and aspiration in poststroke individuals regardless of food consistency.

This article reports on a case history of an elderly patient with Parkinson's disease (PD) who sought treatment at a private dental office. His chief complaint was "difficulty in eating due to an illfitting prosthesis." Laboratory tests and oral radiographs were made. The surgical placement of an implant was done and, subsequently, an implant-supported prosthesis was fitted for the patient. During the impression for the construction of the implant-supported prosthesis, the patient accidentally aspirated the implant screwdriver. The object was found in the lower right lobe of the bronchus, and its removal was necessary in a hospital using bronchoscopy under general anesthesia. Patients with PD are considered at risk of aspirating and/or ingesting dental instruments. Short treatment periods are recommended, preferably during the morning, when the medication prescribed for PD is most effective. When treating patients who have a risk for aspirating and ingesting small objects, it is important to treat them in a more vertical position, and small-sized objects should be secured with dental floss to aid retrieval. © 2011 Special Care Dentistry Association and Wiley Periodicals, Inc.

Rituximab can be safely and effectively used for MAPS. Although detection of only aPS/PT IgM antibody is rare, aPS/PT IgM antibody might be associated with the pathogenesis of MAPS and might be a useful marker of disease activity. © 2017 Japan Pediatric Society.

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. Unfortunately, the patient continued to deteriorate over the next several days and life support was withdrawn on hospital day 16. We present the youngest reported case of Lemierre syndrome and review the literature.

Cerebral salt-wasting syndrome is a condition featuring hyponatremia and dehydration caused by head injury, operation on the brain, subarachnoid hemorrhage, brain tumor and so on. However, there are a few reports of cerebral salt-wasting syndrome caused by cerebral infarction. We describe a patient with cerebral infarction who developed cerebral salt-wasting syndrome in the course of hemorrhagic transformation. A 79-year-old Japanese woman with hypertension and arrhythmia was admitted to our hospital for mild consciousness disturbance, conjugate deviation to right, left unilateral spatial neglect and left hemiparesis. Magnetic resonance imaging revealed a broad ischemic change in right middle cerebral arterial territory. She was diagnosed as cardiogenic cerebral embolism because atrial fibrillation was detected on electrocardiogram on admission. She showed hyponatremia accompanied by polyuria complicated at the same time with the development of hemorrhagic transformation on day 14 after admission. Based on her hypovolemic hyponatremia, she was evaluated as not having syndrome of inappropriate secretion of antidiuretic hormone but cerebral salt-wasting syndrome. She fortunately recovered with proper fluid replacement and electrolyte management. This is a rare case of cerebral infarction and cerebral salt-wasting syndrome in the course of hemorrhagic transformation. It may be difficult to distinguish cerebral salt-wasting syndrome from syndrome of inappropriate antidiuretic hormone, however, an accurate assessment is needed to reveal the diagnosis of cerebral salt-wasting syndrome because the recommended fluid management is opposite in the two conditions.

Untreated auricular hematomas from ear trauma can result in an ear deformation known as cauliflower ear, secondary to fibrosis and new cartilage overgrowth. Cauliflower ear reconstruction has traditionally utilized tools such as a drill or a scalpel in order to improve auricular cosmesis. We present a case report utilizing an ultrasonic aspirator to recontour the fibrosed cartilage of a cauliflower ear. The ultrasonic aspirator has advantages over traditional tools in its ability to provide finely controlled bone removal without damage to surrounding soft tissue. The patient in this case report underwent multistage reconstruction using the ultrasonic aspirator with excellent cosmetic result and patient satisfaction.

Aspiration of human neutrophils: effects of shear thinning and cortical dissipation.

PubMed

Drury, J L; Dembo, M

2001-12-01

It is generally accepted that the human neutrophil can be mechanically represented as a droplet of polymeric fluid enclosed by some sort of thin slippery viscoelastic cortex. Many questions remain however about the detailed rheology and chemistry of the interior fluid and the cortex. To address these quantitative issues, we have used a finite element method to simulate the dynamics of neutrophils during micropipet aspiration using various plausible assumptions. The results were then systematically compared with aspiration experiments conducted at eight different combinations of pipet size and pressure. Models in which the cytoplasm was represented by a simple Newtonian fluid (i.e., models without shear thinning) were grossly incapable of accounting for the effects of pressure on the general time scale of neutrophil aspiration. Likewise, models in which the cortex was purely elastic (i.e., models without surface viscosity) were unable to explain the effects of pipet size on the general aspiration rate. Such models also failed to explain the rapid acceleration of the aspiration rate during the final phase of aspiration nor could they account for the geometry of the neutrophil during various phases of aspiration. Thus, our results indicate that a minimal mechanical model of the neutrophil needs to incorporate both shear thinning and surface viscosity to remain valid over a reasonable range of conditions. At low shear rates, the surface dilatation viscosity of the neutrophil was found to be on the order of 100 poise-cm, whereas the viscosity of the interior cytoplasm was on the order of 1000 poise. Both the surface viscosity and the interior viscosity seem to decrease in a similar fashion when the shear rate exceeds approximately 0.05 s(-1). Unfortunately, even models with both surface viscosity and shear thinning studied are still not sufficient to fully explain all the features of neutrophil aspiration. In particular, the very high rate of aspiration during the

Repetition of the onset of aspiration pneumonia in aged patients is common and causes chronic inflammation. The inflammation induces proinflammatory cytokine production and atrophy in the muscles. The proinflammatory cytokines induce muscle proteolysis by activating calpains and caspase-3, followed by further degradation by the ubiquitin-proteasome system. Autophagy is another pathway of muscle atrophy. However, little is known about the relationship between aspiration pneumonia and muscle. For swallowing muscles, it is not clear whether they produce cytokines. The main objective of this study was to determine whether aspiration pneumonia induces muscle atrophy in the respiratory (the diaphragm), skeletal (the tibialis anterior, TA), and swallowing (the tongue) systems, and their possible mechanisms. We employed a mouse aspiration pneumonia model and computed tomography (CT) scans of aged pneumonia patients. To induce aspiration pneumonia, mice were inoculated with low dose pepsin and lipopolysaccharide solution intra-nasally 5 days a week. The diaphragm, TA, and tongue were isolated, and total RNA, proteins, and frozen sections were stored. Quantitative real-time polymerase chain reaction determined the expression levels of proinflammatory cytokines, muscle E3 ubiquitin ligases, and autophagy related genes. Western blot analysis determined the activation of the muscle proteolysis pathway. Frozen sections determined the presence of muscle atrophy. CT scans were used to evaluate the muscle atrophy in aged aspiration pneumonia patients. The aspiration challenge enhanced the expression levels of proinflammatory cytokines in the diaphragm, TA, and tongue. Among muscle proteolysis pathways, the aspiration challenge activated caspase-3 in all the three muscles examined, whereas calpains were activated in the diaphragm and the TA but not in the tongue. Activation of the ubiquitin-proteasome system was detected in all the three muscles examined. The aspiration challenge

The calcium sensing receptor (CaSR) plays an important role in calcium homeostasis. Activating mutations of CaSR cause autosomal dominant hypocalcemia by affecting parathyroid hormone secretion in parathyroid gland and calcium resorption in kidney. They can also cause a type 5 Bartter syndrome by inhibiting the apical potassium channel in the thick ascending limb of the loop of Henle in the kidney. This study presents a patient who had autosomal dominant hypocalcemia with Bartter syndrome due to an activating mutation Y829C in the transmembrane domain of the CaSR. Symptoms of hypocalcemia occurred 12 days after birth and medication was started immediately. Medullary nephrocalcinosis and basal ganglia calcification were found at 7 years old and at 17 years old. Three hypercalcemic episodes occurred, one at 14 years old and two at 17 years old. The Bartter syndrome was not severe while the serum calcium concentration was controlled, but during hypercalcemic periods, the symptoms of Bartter syndrome were aggravated.

Neonates undergoing heart surgery for CHD are at risk for postoperative gastrointestinal complications and aspiration events. There are limited data regarding the prevalence of aspiration after neonatal cardiothoracic surgery; thus, the effects of aspiration events on this patient population are not well understood. This retrospective chart review examined the prevalence and effects of aspiration among neonates who had undergone cardiac surgery at the time of their discharge. Introduction This study examined the prevalence of aspiration among neonates who had undergone cardiac surgery. Demographic data regarding these patients were analysed in order to determine risk factors for postoperative aspiration. Post-discharge feeding routes and therapeutic interventions were extracted to examine the time spent using alternate feeding routes because of aspiration risk or poor caloric intake. Modified barium swallow study results were used to evaluate the effectiveness of the test as a diagnostic tool. Materials and methods A retrospective study was undertaken of neonates who had undergone heart surgery from July, 2013 to January, 2014. Data describing patient demographics, feeding methods, and follow-up visits were recorded and compared using a χ2 test for goodness of fit and a Kaplan-Meier graph. The patient population included 62 infants - 36 of whom were male, and 10 who were born with single-ventricle circulation. The median age at surgery was 6 days (interquartile range=4 to 10 days). Modified barium swallow study results showed that 46% of patients (n=29) aspirated or were at risk for aspiration, as indicated by laryngeal penetration. In addition, 48% (n=10) of subjects with a negative barium swallow or no swallow study demonstrated clinical aspiration events. Tube feedings were required by 66% (n=41) of the participants. The median time spent on tube feeds, whether in combination with oral feeds or exclusive use of a nasogastric or gastric tube, was 54 days; 44% (n

Community-acquired methicillin-resistant Staphylococcus aureus has been spreading worldwide, including in Japan. However, few cases of toxic shock syndrome caused by Community-acquired methicillin-resistant Staphylococcus aureus have been reported in Japan. We report 2 cases, in middle-aged women, of toxic shock syndrome due to Community-acquired methicillin-resistant Staphylococcus aureus via a vaginal portal of entry. The first patient had used a tampon and the second patient had vaginitis due to a cleft narrowing associated with vulvar lichen sclerosus. Both patients were admitted to our hospital with septic shock and severe acute kidney injury and subsequently recovered with appropriate antibiotic treatment. In our review of the literature, 8 cases of toxic shock syndrome caused by Community-acquired methicillin-resistant Staphylococcus aureus were reported in Japan. In these 8 cases, the main portals of entry were the skin and respiratory tract; however, the portal of entry of Community-acquired methicillin-resistant Staphylococcus aureus from a vaginal lesion has not been reported in Japan previously.

Good syndrome is a rare condition in which thymoma is associated with hypogammaglobulinemia. It is characterized by an increased susceptibility to infections. We report a woman with Good's syndrome diagnosed after severe congenital toxoplasmosis in her daughter, even though she was immunized against this infection during pregnancy. This presentation is very unusual by its early diagnosis and to our knowledge is the first report of parasitic infection in this syndrome. Copyright © 2016. Published by Elsevier SAS.

Papillon-Lefevre syndrome (PLS) is an autosomal recessive disease that is characterized by symmetric palmoplantar keratodermatitis and severe periodontal destruction. Mutations in the cathepsin C gene (CTSC) have recently been detected in PLS. Immune dysregulation, due to a mutation in CTSC, increases the risk of pyogenic infections in PLS patients. A child with PLS is presented here with liver abscesses and peritonitis caused by Rhizopus oryzae. His liver abscess and peritonitis were cured with amphotericin B without surgical care. This is the first case in the literature liver abscess due to Rhizopus oryzae in a child with PLS.

Self-efficacy beliefs as shapers of children's aspirations and career trajectories.

Bandura, A; Barbaranelli, C; Caprara, G V; Pastorelli, C

2001-01-01

This prospective study tested with 272 children a structural model of the network of sociocognitive influences that shape children's career aspirations and trajectories. Familial socioeconomic status is linked to children's career trajectories only indirectly through its effects on parents' perceived efficacy and academic aspirations. The impact of parental self-efficacy and aspirations on their children's perceived career efficacy and choice is, in turn, entirely mediated through the children's perceived efficacy and academic aspirations. Children's perceived academic, social, and self-regulatory efficacy influence the types of occupational activities for which they judge themselves to be efficacious both directly and through their impact on academic aspirations. Perceived occupational self-efficacy gives direction to the kinds of career pursuits children seriously consider for their life's work and those they disfavor. Children's perceived efficacy rather than their actual academic achievement is the key determinant of their perceived occupational self-efficacy and preferred choice of worklife. Analyses of gender differences reveal that perceived occupational self-efficacy predicts traditionality of career choice.

An empirical model of human aspiration in low-velocity air using CFD investigations.

PubMed

Anthony, T Renée; Anderson, Kimberly R

2015-01-01

Computational fluid dynamics (CFD) modeling was performed to investigate the aspiration efficiency of the human head in low velocities to examine whether the current inhaled particulate mass (IPM) sampling criterion matches the aspiration efficiency of an inhaling human in airflows common to worker exposures. Data from both mouth and nose inhalation, averaged to assess omnidirectional aspiration efficiencies, were compiled and used to generate a unifying model to relate particle size to aspiration efficiency of the human head. Multiple linear regression was used to generate an empirical model to estimate human aspiration efficiency and included particle size as well as breathing and freestream velocities as dependent variables. A new set of simulated mouth and nose breathing aspiration efficiencies was generated and used to test the fit of empirical models. Further, empirical relationships between test conditions and CFD estimates of aspiration were compared to experimental data from mannequin studies, including both calm-air and ultra-low velocity experiments. While a linear relationship between particle size and aspiration is reported in calm air studies, the CFD simulations identified a more reasonable fit using the square of particle aerodynamic diameter, which better addressed the shape of the efficiency curve's decline toward zero for large particles. The ultimate goal of this work was to develop an empirical model that incorporates real-world variations in critical factors associated with particle aspiration to inform low-velocity modifications to the inhalable particle sampling criterion.

2018-03-01

Based on Globocan data in 2012, it is estimated that about 14,495 Indonesians suffer from lymphoma, both Hodgkin’s lymphoma, and non-Hodgkin’s lymphoma. Some areas of specialization still doubt the accuracy of cytology diagnosis of fine needle aspiration biopsy.This study is a diagnostic test with a cross sectional analytic design to see how the cytology diagnostic accuracy of fine needle aspiration aspirate in lymphoma. It was in Department of Anatomical Pathology Faculty of Medicine USU, Haji Adam Malik Hospital, Dr.Pirngadi hospital, or private clinic in Medan. Peripheral cytology technique biopsy of fine needle aspiration on lymph node subsequently stained with Giemsa, when the cytology of lymphoma is obtained and confirmed by histopathologic examination. Cytology and histopathologic examination will be tested by Diagnostic Test and assessed for its sensitivity and specificity. The diagnostic of lymphoma cytology provides 93.33% sensitivity and 92.31% specificity when confirmed by histopathological examination. Positive predictive value and negative predictive value of 96.55% and 85.71% respectively. In conclusion, the cytology of fine needle aspiration biopsy is accurate enough to be used as a diagnostic tool, so it is advisable to establish a lymphoma diagnosis to perform a needle aspiration biopsy examination.

2017-01-01

Background and aim Neonatal respiratory distress syndrome is a leading cause of morbidity in preterm new-born babies (<37 weeks gestation age). The current diagnostic reference standard includes clinical testing and chest radiography with associated exposure to ionising radiation. The aim of this review was to compare the diagnostic accuracy of lung ultrasound against the reference standard in symptomatic neonates of ≤42 weeks gestation age. Methods A systematic search of literature published between 1990 and 2016 identified 803 potentially relevant studies. Six studies met the review inclusion criteria and were retrieved for analysis. Quality assessment was performed before data extraction and meta-analysis. Results Four prospective cohort studies and two case control studies included 480 neonates. All studies were of moderate methodological quality although heterogeneity was evident across the studies. The pooled sensitivity and specificity of lung ultrasound were 97% (95% confidence interval [CI] 94–99%) and 91% (CI: 86–95%) respectively. False positive diagnoses were made in 16 cases due to pneumonia (n = 8), transient tachypnoea (n = 3), pneumothorax (n = 1) and meconium aspiration syndrome (n = 1); the diagnoses of the remaining three false positive results were not specified. False negatives diagnoses occurred in nine cases, only two were specified as air-leak syndromes. Conclusions Lung ultrasound was highly sensitive for the detection of neonatal respiratory distress syndrome although there is potential to miss co-morbid air-leak syndromes. Further research into lung ultrasound diagnostic accuracy for neonatal air-leak syndrome and economic modelling for service integration is required before lung ultrasound can replace chest radiography as the imaging component of the reference standard.

Bio rapid prototyping by extruding/aspirating/refilling thermoreversible hydrogel.

PubMed

Iwami, K; Noda, T; Ishida, K; Morishima, K; Nakamura, M; Umeda, N

2010-03-01

This paper reports a method for rapid prototyping of cell tissues, which is based on a system that extrudes, aspirates and refills a mixture of cells and thermoreversible hydrogel as a scaffold. In the extruding mode, a cell-mixed scaffold solution in the sol state is extruded from a cooled micronozzle into a temperature-controlled substrate, which keeps the scaffold in the gel state. In the aspiration mode, the opposite process is performed by Bernoulli suction. In the refilling mode, the solution is extruded into a groove created in the aspiration mode. The minimum width of extruded hydrogel pattern is 114 +/- 15 microm by employing a nozzle of diameter 100 microm, and that of aspirated groove was 355 +/- 10 microm using a 500 microm-diameter nozzle. Gum arabic is mixed with the scaffold solution to avoid peeling-off of the gel pattern from the substrate. Patterning of Sf-9 cell tissue is demonstrated, and the stability of the patterned cell is investigated. This system offers a procedure for rapid prototyping and local modification of cell scaffolds for tissue engineering.

2017-01-01

The aspiration of a foreign body remains a common paediatric problem, with serious consequences that can produce both acute and chronic disease. Aspiration usually causes a medical emergency that requires a prompt diagnosis and an urgent therapeutic approach as it may result in the death of the child or severe brain injury. It typically involves organic foreign bodies (mainly food or nuts) aspirated by children under 5 years old, and usually at home. In this statement, the Committee on Safety and Prevention of Non-Intentional Injury in Childhood of the Spanish Paediatrics Association provides a series of recommendations, both educational (while eating and playing), as well as legal, to prevent such episodes.

Economic, occupational, and social shifts in rural economies have influenced nuanced changes in the educational and occupational aspirations of rural adolescent women and men. However, there is limited contemporary research that examines the aspirations of rural adolescents at the beginning of the 21st century. Drawing on a sample of 8,756 rural adolescents in the United States, we examine how familial, geographic, and economic variables influence gender-related differences in educational and occupational aspirations. Findings revealed significant gender differences, favoring girls, in youth's educational aspirations, occupational aspirations, and aspirations for nontraditional careers. Results highlight the importance of contextual variables such as parental expectations, family income, and motivation variables in predicting gender-related aspirations of rural youth. PMID:26681990

Can nature make us more caring? Effects of immersion in nature on intrinsic aspirations and generosity.

PubMed

Weinstein, Netta; Przybylski, Andrew K; Ryan, Richard M

2009-10-01

Four studies examined the effects of nature on valuing intrinsic and extrinsic aspirations. Intrinsic aspirations reflected prosocial and other-focused value orientations, and extrinsic aspirations predicted self-focused value orientations. Participants immersed in natural environments reported higher valuing of intrinsic aspirations and lower valuing of extrinsic aspirations, whereas those immersed in non-natural environments reported increased valuing of extrinsic aspirations and no change of intrinsic aspirations. Three studies explored experiences of nature relatedness and autonomy as underlying mechanisms of these effects, showing that nature immersion elicited these processes whereas non-nature immersion thwarted them and that they in turn predicted higher intrinsic and lower extrinsic aspirations. Studies 3 and 4 also extended the paradigm by testing these effects on generous decision making indicative of valuing intrinsic versus extrinsic aspirations.

Recent studies have reported perioperative pulmonary aspiration in pediatric practice to be an uncommon problem associated with low morbidity and mortality. This paper examines the recent publications in both the adult and pediatric literature and looks at some of the potential risk factors involved, both patient and anesthetic, in the development of aspiration of gastric contents. We also look at the risk of severe morbidity following pulmonary aspiration and speculate on possible reasons behind the assertion that pulmonary aspiration in pediatric anesthetic practice is rare and a low-risk event. © 2014 John Wiley & Sons Ltd.

Microincision, aspiration cutter-assisted multifocal iris biopsy for melanoma.

Finger, Paul T; Milman, Tatyana

To describe a minimally invasive method to create multifocal full-thickness surgical iridectomy biopsies. Seven patients suspected to have diffuse iris melanoma underwent multifocal surgical iridectomy biopsy through a single 1.0-mm clear corneal incision. A 25-G inked trocar was used to create one visible corneal portal, through which the anterior chamber was filled with sodium hyaluronate 1%. Then, a 25-G aspiration cutter probe was introduced through the corneal incision such that the aspiration portal was occluded by the iris biopsy sites. Then aspiration (600 mm Hg) cutting (300 cuts per minute) was used to create full- and partial-thickness surgical iridectomy biopsies at multiple locations. After each biopsy the probe was removed, and its contents aspirated into a separate 3-mL syringe (marked by clock hour location). The sodium hyaluronate 1% was removed and wound checked for leakage. Diagnostic specimens were obtained in all cases. Five were found to be diffuse iris melanomas and 2 were indeterminate iris melanocytic proliferations. No patients developed a secondary increase in intraocular pressure, hyphema, infection, cataract, or vision loss. No cases of intraocular tumor dissemination were observed. No patient complained of glare or monocular diplopia. Three of 7 corneal wounds were self-sealing. Multifocal surgical iridectomy biopsy can be minimally invasive and effective allowing for partial- and full-thickness iris biopsy. Use of a 25-G aspiration cutting probe allowed for small incision surgery, rapid rehabilitation, and no significant complications.

Adolescents from areas of high deprivation are often assumed to have low aspirations for the future. However, recent research has suggested otherwise and there have been calls for more substantial investigation into the relationship between poverty and aspiration. This article reports levels and variation in aspiration from 1214 adolescents (49.5 % male; 50.5 % female) living in areas of high deprivation across 20 London boroughs. A strength of this study is our large and diverse population of low socio-economic status (SES) adolescents, comprising of white British (22 %), black African (21 %), black Caribbean (9 %), Indian/Pakistani/Bangladeshi/Other Asian (24 %), mixed ethnicity (9 %), and 15 % defining themselves as Other. Our measures indicated a high group level of reported aspiration with notable variations. Females reported higher educational (but not occupational) aspirations than males; white British students reported lower educational and occupational aspirations than other ethnic groups; and black African children reported the highest educational aspirations. Perceived parental support for education had the largest positive association with aspirations. In contrast to previous findings from studies carried out in the United States, aspirations were found to be negatively associated with perceptions of school and school peer environment. These measures explored feelings of safety, happiness and belonging within the school environment and school peer group. We discuss possible explanations for this unexpected finding within our population of adolescents from UK state schools and how it might affect future policy interventions. This study makes an important contribution to the literature on adolescent aspirations because of the unique nature of the data sample and the multiple domains of functioning and aspiration measured.

2009-04-01

We set out to ascertain the evolution and the clinical and videofluoroscopic (VFS) prognostic factors of aspiration recovery and return to oral intake in patients with stroke and VFS diagnosis of tracheal aspiration. Twenty patients with stroke and VFS diagnosis of tracheal aspiration were prospectively evaluated. Clinical evaluation of oropharyngeal dysphagia and VFS examination were performed at admission and repeated at 1, 3, 6 and 12 months of follow-up. At admission, videofluoroscopy showed 40% of patients to have an increase in oral transit time and 65% impaired tongue control; in the pharyngeal phase, mean pharyngeal transit time was increased in 70% of patients and the time required to trigger the swallowing reflex was delayed in 70%. During follow-up, an improvement was observed, and the number of patients with aspiration decreased progressively (the most significant change occurred at 6 months). Evolution was related to the vascular territory affected: at 1 year, aspiration persisted in 12% of anterior territory lesions vs. 58% of posterior territory lesions. Also, the number of silent aspirators decreased from 35% at baseline to no patients after 3 months. Persistent aspiration at 1 year of follow-up significantly correlated with the following baseline variables: vascular territory, gag reflex abolition, palatoglossal seal alteration and pharyngeal delay time. Swallowing physiology in stroke greatly improved during follow-up, mainly between 3 and 6 months, and the number of aspirations decreased progressively. Prognostic factors for persisting aspiration are posterior vascular territory lesions, oropharyngeal reflex abolition, palatoglossal seal alteration and pharyngeal delay time at baseline.

Coevolutionary dynamics of aspiration and strategy in spatial repeated public goods games

NASA Astrophysics Data System (ADS)

Wu, Te; Fu, Feng; Wang, Long

2018-06-01

The evolutionary dynamics remain largely unknown for spatial populations where individuals are more likely to interact repeatedly. Under this settings, individuals can make their decisions to cooperate or not based on the decisions previously adopted by others in their neighborhoods. Using repeated public goods game, we construct a spatial model and use a statistical physics approach to study the coevolutionary dynamics of aspiration and strategy. Individuals each have an aspiration towards the groups they are involved. According to the outcome of each group, individuals have assessment of whether their aspirations are satisfied. If satisfied, they cooperate next round. Otherwise, they switch to defecting. Results show threshold phenomenon for harsh collective dilemma: cooperators sticking to high levels of aspiration can prevail over defectors, while cooperators with other levels are invariably wiped out. When the collective dilemma is relaxed, cooperation is greatly facilitated by inducing a high level of diversity of aspiration. Snapshots further show the spatial patterns of how this coevolutionary process leads to the emergence of an optimal solution associated with aspiration level, whose corresponding strategy are most prevalent. This optimal solution lies in one and the highest aspiration level allowed, and depends on the intensity of the social dilemma. By removing the memory effect, our results also confirm that repeated interactions can promote cooperation, but to a limited degree.

The diagnostic value of gastroesophageal reflux disease (GERD) symptoms and detection of pepsin and bile acids in bronchoalveolar lavage fluid and exhaled breath condensate for identifying lung transplantation patients with GERD-induced aspiration.

Gastroesophageal reflux disease (GERD) is thought to lead to aspiration and bronchiolitis obliterans syndrome after lung transplantation. Unfortunately, the identification of patients with GERD who aspirate still lacks clear diagnostic indicators. The authors hypothesized that symptoms of GERD and detection of pepsin and bile acids in the bronchoalveolar lavage fluid (BAL) and exhaled breath condensate (EBC) are effective for identifying lung transplantation patients with GERD-induced aspiration. From November 2009 to November 2010, 85 lung transplantation patients undergoing surveillance bronchoscopy were prospectively enrolled. For these patients, self-reported symptoms of GERD were correlated with levels of pepsin and bile acids in BAL and EBC and with GERD status assessed by 24-h pH monitoring. The sensitivity and specificity of pepsin and bile acids in BAL and EBC also were compared with the presence of GERD in 24-h pH monitoring. The typical symptoms of GERD (heartburn and regurgitation) had modest sensitivity and specificity for detecting GERD and aspiration. The atypical symptoms of GERD (aspiration and bronchitis) showed better identification of aspiration as measured by detection of pepsin and bile acids in BAL. The sensitivity and specificity of pepsin in BAL compared with GERD by 24-h pH monitoring were respectively 60 and 45 %, whereas the sensitivity and specificity of bile acids in BAL were 67 and 80 %. These data indicate that the measurement of pepsin and bile acids in BAL can provide additional data for identifying lung transplantation patients at risk for GERD-induced aspiration compared with symptoms or 24-h pH monitoring alone. These results support a diagnostic role for detecting markers of aspiration in BAL, but this must be validated in larger studies.

Our study aims to follow this effort and to explore the association between health, socioeconomic background, school-related factors, social support and adolescents' sense of coherence and educational aspirations among adolescents from different educational tracks and to contribute to the existing body of knowledge on the role of educational aspirations in the social reproduction of health inequalities. We expect that socioeconomic background will contribute to the development of educational aspirations, but this association will be modified by available social and individual resources, which may be particularly favourable for the group of adolescents who are on lower educational tracks, since for them such resources may lead to gaining a higher educational level. We collected data on the socioeconomic background (mother's and father's education and employment status, doubts about affordability of future study), school-related factors (school atmosphere, school conditions, attitudes towards school), perceived social support, sense of coherence (manageability, comprehensibility, meaningfulness) and the self-rated health of a national sample of Slovak adolescents (n = 1992, 53.5% females, mean age 16.9 years). We assessed the association of these factors with educational aspirations, overall and by educational tracks (grammar schools, specialised secondary schools, vocational schools). We found statistically significant associations with educational aspirations for the factors parental educational level, father's unemployment, doubts about the affordability of future study, school atmosphere, attitude towards school, social support from the father and a sense of coherence. Social support from the mother and friends was not associated with educational aspiration, nor was self-rated health.

To evaluate the number and types of underlying disorders detected in dogs with aspiration pneumonia and determine the survival rate among affected dogs. Retrospective case series. Animals-88 dogs with aspiration pneumonia. Medical records were reviewed to identify disease processes that could result in aspiration pneumonia. To assess outcome (ie, survival to discharge from the hospital or nonsurvival), dogs were grouped by the type and number of underlying disease processes. Duration of hospitalization and radiographic severity of disease were evaluated with regard to case outcome. As the cause of aspiration pneumonia, a single underlying disorder was identified in 60 of the 88 dogs; 2 or more diseases were identified in the remaining dogs. Esophageal disease (n = 35), vomiting (34), neurologic disorders (24), laryngeal disease (16), and postanesthetic aspiration (12) were identified most commonly. Overall, 68 dogs survived to discharge from the hospital (survival rate, 77%). Survival rates were comparable among dogs regardless of the underlying cause of aspiration pneumonia. Radiographic severity of disease and duration of hospitalization did not influence survival. Among these study dogs, aspiration pneumonia was associated with a high survival rate. The presence of more than 1 underlying disease associated with aspiration pneumonia did not adversely impact survival rate. Interestingly, radiographic severity of disease and duration of hospitalization were not associated with overall survival rate.

Bladder outlet obstruction treated with transurethral ultrasonic aspiration

1991-07-01

Fifty-nine males with bladder outlet obstruction were treated with transurethral ultrasonic aspiration of the prostate. Utilizing a 26.5 French urethral sheath, surgery was accomplished with a 10 French, 0-700 micron vibration level ultrasonic tip with an excursion rate of 39 kHz. Complete removal of the adenoma was accomplished, followed by transurethral electrocautery biopsies of both lateral lobes to compare pathologic specimens. One-year follow-up revealed satisfactory voiding patterns in 57 of 59 men (96%). Two men developed bladder neck contractures. Pathologic comparisons showed 100% correlation between aspirated and TUR specimens (56 BPH, 3 adeno-carcinoma). Forty-sevel men were active sexually preoperatively (6 with inflatable penile prostheses). Post ultrasonic aspiration, 46 men had erectile function similar to preoperative levels with one patient suffering erectile dysfunction. Forty men (85%) had antegrade ejaculation while 7 (15%) experienced retrograde or retarded ejaculation. No patients were incontinent.

Patients with head and neck cancer (HNC) are at high risk for oropharyngeal dysphagia (OD) following surgical therapy. Early identification of OD can improve outcomes and reduce economic burden. This study aimed to evaluate the validity of a water screening test using increasing volumes postsurgically for patients with HNC (N=80) regarding the early identification of OD in general, and whether there is a need for further instrumental diagnostics to investigate the presence of aspiration as well as to determine the limitations of oral intake as defined by fiberoptic endoscopic evaluation of swallowing. OD in general was identified in 65%, with aspiration in 49%, silent aspiration in 21% and limitations of oral intake in 56%. Despite a good sensitivity, for aspiration of 100% and for limitations of oral intake of 97.8%, the presented water screening test did not satisfactorily predict either of these reference criteria due to its low positive likelihood ratio (aspiration=2.6; limitations of oral intake=3.1). However, it is an accurate tool for the early identification of OD in general, with a sensitivity of 96.2% and a positive likelihood ratio of 5.4 in patients after surgery for HNC.

Long-term survival of a pulmonary allograft is currently hampered by obliterative bronchiolitis (OB), a form of chronic rejection that is unique to lung transplantation. While tracheobronchial aspiration from gastroesophageal reflux disease (GERD) has clinically been associated with OB, no experimental model exists to investigate this problem. Using a WKY-to-F344 rat orthotopic left lung transplant model, the effects of chronic aspiration on pulmonary allograft were evaluated. Recipients received cyclosporine with or without 8 weekly aspirations of gastric fluid into the allograft. Six (66.7%) of 9 allografts with aspiration demonstrated bronchioles with surrounding monocytic infiltrates, fibrosis and loss of normal lumen anatomy, consistent with the development of OB. In contrast, none of the allografts without aspiration (n = 10) demonstrated these findings (p = 0.002). Of the grafts examined grossly, 83% of the allografts with chronic aspiration but only 20% without aspiration appeared consolidated (p = 0.013). Aspiration was associated with increased levels of IL-1 alpha, IL-1 beta, IL-6, IL-10, TNF-alpha and TGF-beta in BAL and of IL-1 alpha, IL-4 and GM-CSF in serum. This study provides experimental evidence linking chronic aspiration to the development of OB and suggests that strategies aimed at preventing aspiration-related injuries might improve outcomes in clinical lung transplantation.

"Diesel siphoner's lung": Exogenous lipoid pneumonia following hydrocarbon aspiration.

2014-01-01

Lipoid pneumonia is an unusual and uncommon form of pneumonia caused by aspiration of fatty substances. Hydrocarbon pneumonitis following aspiration of diesel is a form of exogenous lipoid pneumonia wherein, aspirated diesel reaches the alveoli rapidly without evoking any significant cough, but initiates an intense inflammatory reaction in the pulmonary parenchyma. This is a rarely described clinical scenario, although the practice of diesel siphonage from automobiles is a common practice in developing countries. We herein describe a 40-year-old male patient, in whom the diagnosis of lipoid pneumonia was delayed for a long duration and highlight the importance of taking a detailed occupational exposure history in patients with non-resolving pneumonia to rule out the underlying possibility of this rare clinical entity.

Pathologic Femoral Neck Fracture Due to Fanconi Syndrome Induced by Adefovir Dipivoxil Therapy for Hepatitis B

Lee, Yoon-Suk; Kim, Byung-Kook; Lee, Ho-Jae

2016-01-01

In Fanconi syndrome, hypophosphatemic osteomalacia is caused by proximal renal tubule dysfunction which leads to impaired reabsorption of amino acids, glucose, urate, and phosphate. We present a rare case of a 43-year-old Korean male who was found to have insufficiency stress fracture of the femoral neck secondary to osteomalacia due to Fanconi syndrome. He had been receiving low-dose adefovir dipivoxil (ADV, 10 mg/day) for the treatment of chronic hepatitis B virus infection for 7 years and he subsequently developed severe hypophosphatemia and proximal renal tubule dysfunction. The incomplete femoral neck fracture was fixed with multiple cannulated screws to prevent further displacement of the initial fracture. After cessation of ADV and correction of hypophosphatemia with oral phosphorus supplementation, the patient's clinical symptoms, such as bone pain, muscle weakness, and laboratory findings improved.

Foreign body aspiration in children.

PubMed

Lima, João A B; Fischer, Gilberto Bueno

2002-12-01

Foreign body aspiration is a common accident in children and represents an important cause of morbidity and mortality. Diagnosis of this condition demands a high degree of suspicion since physical examination and basic radiology exams have low sensitivity. It is more frequent in children younger than 3 years of age, predominantly boys. Food materials are most commonly involved, particularly peanuts, although this could change according to regional feeding habits. The right main bronchus is the site where foreign bodies are most commonly found. Radiographical findings are not diagnostic, but the presence of unilateral obstructive emphysema or atelectasis are important clues. A rigid endoscopy is indicated whenever there is a suggestive history, since delays in removing foreign bodies can lead to severe bronchial sequelae. In developing countries this type of accident may be more relevant due to the lack of resources and awareness, which can lead to late diagnosis and treatment. Routine preventive measures must be taught to caregivers in order to reduce the incidence. Health care professionals should also be made more aware of the prevalence of this condition.

Foreign body aspiration (FBA) continues to be a concerning pediatric problem, accounting for thousands of emergency room visits and more than 100 deaths each year in the United States. The costs incurred with hospitalizations and procedures following these events are the focus of this study. Retrospective review. The Nationwide Inpatient Sample from 2009 to 2011 was analyzed, and all cases with pediatric bronchial foreign body aspirations (International Classification of Diseases-9 codes: 934.0, 934.1, 934.8, and 934.9) were reviewed. Cases were analyzed to determine type of foreign body aspiration, procedural interventions performed, duration of inpatient stay, mortality rate, complications, and posthospitalization disposition. The median length of hospital stay and total costs associated with aspiration events were determined. An estimated 1,908 ± 273 pediatric bronchial FBA patients were admitted annually over the 3-year period (mean age, 3.6 ± 0.3 years; 61.3% ± 1.9% male). The ratio of foreign object aspiration to food aspiration was 5:3. Overall, 56%.0 ± 3.6% of the patients underwent a bronchoscopic procedure for foreign body removal; of those, 41.5% ± 2.5% had a foreign body removed at the time of the endoscopy. The hospital mortality rate associated with bronchial aspiration was 1.8% ± 0.4%; and 2.2% ± 0.5% of patients were diagnosed with anoxic brain injury. The median length of stay was 3 days (25th-75th interquartile range, 1-7 days).The median charges and actual costs per case were $20,820 ($10,800-$53,453) and $6,720 ($3,628-$16,723), respectively. The annual overall inpatient cost associated with pediatric bronchial foreign-body aspiration is approximately $12.8 million. Combined, the rate of death or anoxic brain injury associated with pediatric foreign body is approximately 4%. 2C. © 2014 The American Laryngological, Rhinological and Otological Society, Inc.

ICF syndrome is a primary immunodeficiency disease characterized by hypo- or agammaglobulinemia, centromeric instability mainly on chromosomes 1, 9, and 16 and facial anomalies. ICF syndrome presents with frequent respiratory tract infections in infancy. A 20-month-old female patient was referred to our clinic due to frequent lower respiratory tract infections. ICF syndrome was considered because of comorbidity of hypogammaglobulinemia, facial anomalies, and neuromotor growth retardation. Metaphase chromosome analysis revealed centromeric instability on chromosomes 1, 9, and 16 and through Sanger a previously unreported homozygous missense mutation (c.1805T>C; [p.V602A]) was identified in the DNMT3B, confirming ICF1. The patient was found to have a breakdown in renal function 1 year later; the urinary system was examined and bilateral vesicoureteral reflux was found, warranting the need for dialysis in time. This report expands the mutation spectrum of ICF1 and is the first to describe bilateral vesicoureteral reflux accompanying ICF syndrome. © 2016 Wiley Periodicals, Inc. © 2016 Wiley Periodicals, Inc.

Postoperative hemorrhage is a significant cause of morbidity and mortality following liver resection. It typically presents early within the postoperative period, and conservative management is possible in the majority of cases. We present a case of late post-hepatectomy hemorrhage associated with overt abdominal compartment syndrome resulting from a localized functional compartment within the abdomen. A 68-year-old white man was readmitted with sudden onset of upper abdominal pain, vomiting, and hemodynamic instability 8 days after an uneventful hepatic resection for metachronous colon cancer metastasis. A frozen abdomen with adhesions due to complicated previous abdominal surgeries was encountered at the first intervention, but the surgery itself and initial recovery were otherwise unremarkable. Prompt response to fluid resuscitation at admission was followed by a computed tomography of his abdomen that revealed active arterial hemorrhage in the liver resection site and hemoperitoneum (estimated volume <2 L). Selective arteriography successfully identified and embolized a small bleeding branch of his right hepatic artery. He remained hemodynamically stable, but eventually developed overt abdominal compartment syndrome. Surgical exploration confirmed a small volume of ascites and blood clots (1.2 L) under significant pressure in his supramesocolic region, restricted by his frozen lower abdomen, which we evacuated. Dramatic improvement in his ventilatory pressure was immediate. His abdomen was left open and a negative pressure device was placed for temporary abdominal closure. The fascia was formally closed after 48 hours. He was discharged home at postoperative day 6. Intra-abdominal pressure and radiologic findings of intra-abdominal hemorrhage should be carefully interpreted in patients with extensive intra-abdominal adhesions. A high index of suspicion and detailed understanding of abdominal compartment mechanics are paramount for the timely diagnosis of

Turner syndrome presents with one of the most frequent chromosomal aberrations in female, typically presented with growth retardation, ovarian insufficiency, facial dysmorphism, and numerous other somatic stigmata. Gigantism is an extremely rare condition resulting from an excessive growth hormone (GH) secretion that occurs during childhood before the fusion of epiphyseal growth plates. The major clinical feature of gigantism is growth acceleration, although these patients also suffer from hypogonadism and soft tissue hypertrophy. We presented a girl with mosaic Turner syndrome, delayed puberty and normal linear growth for the sex and age, due to the simultaneous GH hypersecretion by pituitary tumor. In the presented case all the typical phenotypic stigmata related to Turner syndrome were missing. Due to excessive pituitary GH secretion during the period while the epiphyseal growth plates of the long bones are still open, characteristic stagnation in longitudinal growth has not been demonstrated. The patient presented with delayed puberty and primary amenorrhea along with a sudden appearance of clinical signs of hypersomatotropinism, which were the reasons for seeking medical help at the age of 16. Physical examination of children presenting with delayed puberty but without growth arrest must include an overall hormonal and genetic testing even in the cases when typical clinical presentations of genetic disorder are absent. To the best of our knowledge, this is the first reported case of simultaneous presence of Turner syndrome and gigantism in the literature.

2014-12-01

A total of 30 children and adolescents with dysphagia due to various chronic neurological disorders were assessed for their risk of aspiration. This assessment was performed clinically by experienced speech and swallowing therapists, and verified thereafter by fiberoptic endoscopy. We found the clinical judgment to be correct in only 70% (for aspiration of saliva), 55% (of puree), and 67% (of thin liquids). We conclude that, because of this unacceptably high error rate of clinical assessment, a fiberoptic evaluation of swallowing is a necessary diagnostic step both for the planning of therapy and for the development of feeding strategies in children and adolescents with neurogenic dysphagia.

This effort is to develop large diameter (22 - 36 inch) Aspirating Seals for application in aircraft engines. Stein Seal Co. will be fabricating the 36-inch seal(s) for testing. GE's task is to establish a thorough understanding of the operation of Aspirating Seals through analytical modeling and full-scale testing. The two primary objectives of this project are to develop the analytical models of the aspirating seal system, to upgrade using GE's funds, GE's 50-inch seal test rig for testing the Aspirating Seal (back-to-back with a corresponding brush seal), test the aspirating seal(s) for seal closure, tracking and maneuver transients (tilt) at operating pressures and temperatures, and validate the analytical model. The objective of the analytical model development is to evaluate the transient and steady-state dynamic performance characteristics of the seal designed by Stein. The transient dynamic model uses a multi-body system approach: the Stator, Seal face and the rotor are treated as individual bodies with relative degrees of freedom. Initially, the thirty-six springs are represented as a single one trying to keep open the aspirating face. Stops (Contact elements) are provided between the stator and the seal (to compensate the preload in the fully-open position) and between the rotor face and Seal face (to detect rub). The secondary seal is considered as part of the stator. The film's load, damping and stiffness characteristics as functions of pressure and clearance are evaluated using a separate (NASA) code GFACE. Initially, a laminar flow theory is used. Special two-dimensional interpolation routines are written to establish exact film load and damping values at each integration time step. Additionally, other user-routines are written to read-in actual pressure, rpm, stator-growth and rotor growth data and, later, to transfer these as appropriate loads/motions in the system-dynamic model. The transient dynamic model evaluates the various motions, clearances

Pulmonary aspiration under GA: a 13-year audit in a tertiary pediatric unit.

Pulmonary aspiration is a known risk of general anesthesia. We aim to find out the incidence, risk factors, and outcome of pulmonary aspiration in our pediatric population. Since 2000, all critical incidents are reported on a standardized audit form. All cases with pulmonary aspiration being reported as a critical incident were identified and their case notes traced to look at the perioperative details. From 2000 to 2013, a total of 102 425 pediatric cases were done in our hospital. Twenty-two cases were reported to have aspirated during anesthesia giving an incidence of 0.02% (1 in 4655). Majority (59.0%) of the children were between the ages of 3-12 and of ASA 1 (54.5%). None of them had any history of pulmonary aspiration. Of the 22 cases, 12 occurred during induction, three during maintenance, three during emergence, three during recovery, and one occurred preinduction. Twelve cases had intravenous induction while the rest received inhalational induction. The type of induction does not appear to affect the incidence of aspiration (OR 1.139 95% CI: 0.457-2.818 P = 0.76). Two cases were found to have a difficult airway during induction and 45.5% were emergency operations. Emergency surgeries put the patient at a higher risk of aspiration (OR 4.321 95% CI: 1.735-10.687 P = 0.001). No mortality was reported. Surgery was canceled for one patient, two had unplanned admissions, seven were admitted to high dependency unit or intensive care unit with two requiring postoperative ventilation. The incidence of aspiration under general anesthesia in our hospital is comparable to published reports. Our audit highlights the fact that pulmonary aspiration although rare mostly occur in healthy ASA 1 and 2 children with no prior history. Emergency surgeries put the patient at a higher risk of aspiration. They occurred usually during induction, a process which tends to be variable (in technique and duration) for pediatric patients. © 2016 John Wiley & Sons Ltd.

UNCERTAINTY IN EARLY OCCUPATIONAL ASPIRATIONS: ROLE EXPLORATION OR AIMLESSNESS?

Many youth in the United States lack clear occupational aspirations. This uncertainty in achievement ambitions may benefit socioeconomic attainment if it signifies “role exploration,” characterized by career development, continued education, and enduring partnerships. By contrast, uncertainty may diminish attainment if it instead leads to “aimlessness,” involving prolonged education without the acquisition of a degree, residential dependence, and frequent job changes. We use nationally representative data from the National Education Longitudinal Study (NELS) to examine how uncertainty in occupational aspirations in adolescence (age 16) affects wage attainments in young adulthood (age 26). Results suggest that youth with uncertain career ambitions earn significantly lower hourly wages in young adulthood than youth with professional and non-professional aspirations, supporting the view that uncertainty heightens the risk of labor-market problems.

Aspiration-based coevolution of link weight promotes cooperation in the spatial prisoner's dilemma game

2018-05-01

In this article, we propose an aspiration-based coevolution of link weight, and explore how this set-up affects the evolution of cooperation in the spatial prisoner's dilemma game. In particular, an individual will increase the weight of its link to its neighbours only if the payoff received via this interaction exceeds a pre-defined aspiration. Conversely, if the received payoff is below this aspiration, the link weight with the corresponding neighbour will decrease. Our results show that an appropriate aspiration level leads to a high-cooperation plateau, whereas too high or too low aspiration will impede the evolution of cooperation. We explain these findings with a comprehensive analysis of transition points and with a systematic analysis of typical configuration patterns. The presented results provide further theoretical insights with regards to the impact of different aspiration levels on cooperation in human societies.

Age and Sex Differences in the Vocational Aspirations of Elementary School Children.

Hewitt, Lynn Stewart

1975-08-01

Four hypotheses were proposed: (a) boys would aspire to a greater variety of vocations than girls; (b) boys would change their vocational preferences more frequently than girls; (c) older boys would aspire to a broader range of vocations than younger boys; and (d) older girls would aspire to a similar or smaller range of vocations than younger girls. A total of 128 6- and 8-year-old Dutch boys and girls responded to questions concerning their vocational aspirations. All the hypotheses except (b) received support. The results suggested that sex-role expectations for adult occupations are acquired very early and, moreover, strongly circumscribe the range of vocations perceived as appropriate for females.

Tumour cell dispersion by the ultrasonic aspirator during brain tumour resection.

PubMed

Preston, J K; Masciopinto, J; Salamat, M S; Badie, B

1999-10-01

Ultrasonic aspirators are commonly used to resect brain tumours because they allow safe, rapid and accurate removal of diseased tissue. Since ultrasonic aspirators generate a spray of aerosolized irrigating fluid around the instrument tip, we questioned whether this spray might contain viable tumours cells that could contribute to intraoperative spread of tumour fragments. To test this hypothesis, we collected the spray produced during the resection of nine brain tumours with an ultrasonic aspirator and semi-quantitatively analysed it for tumour presence. The aerosolized irrigation fluid was found to contain intact tumour cells or clumps of tumour cells in all nine instances, and there was a trend of increasing tumour cell dispersion with increasing ultrasonic aspiration times. Further examination is required to determine if this intraoperative dispersion of apparently viable tumour fragments contributes to local neoplasm recurrence.

Succinate dehydrogenase (SDH) deficiency is rare. Clinical manifestations can appear in infancy with a marked impairment of psychomotor development with pyramidal signs and extrapyramidal rigidity. A 10-month-old boy developed severe neurological features, evoking a Leigh syndrome; magnetic resonance imaging showed features of leukodystrophy. A deficiency in the complex II respiratory chain (succinate dehydrogenase [SDH]) was shown. The course was remarkable by the regression of neurological impairment under treatment by riboflavin. The delay of psychomotor development, mainly involving language, was moderate at the age of 5 years. The relatively good prognosis of this patient, despite severe initial neurological impairment, may be due to the partial enzyme deficiency and/or riboflavin administration.

Structural and socio-psychological influences on adolescents’ educational aspirations and subsequent academic achievement

PubMed Central

2011-01-01

Previous literature indicates that educational aspirations are an important predictor of achievement at school and beyond. This paper examines the factors that are associated with high educational aspirations. It also looks at the relationship between aspirations and achievement at the General Certificate of Secondary Education in a deprived area of London. The results show that educational aspirations are associated with individual characteristics. Girls were more likely than boys to express a wish to remain in education beyond the age of 16. For the most academic route post-16, there were substantial ethnic differences, with minority ethnic groups generally being more likely to state a desire to follow this path. Students who were eligible for free school meals tended to have lower aspirations. Socio-psychological variables were also shown to be of importance, particularly self-esteem and psychological distress. Importantly, educational aspirations had a strong association with actual achievement at age 16, remaining associated even after controlling for a number of other variables, including prior achievement. These findings are discussed in light of previous research and potential intervention strategies. PMID:21532940

Objective: To evaluate the efficacy of aspiration in an opposite position to deal with pneumothorax after CT-guided lung biopsy. Methods: A retrospective study was developed involving 210 patients with pneumothorax who had undergone CT-guided percutaneous core biopsies from January 2012 to March 2014 for various pulmonary lesions. Asymptomatic patients with minimal pneumothorax were treated conservatively. Simple manual aspiration was performed for symptomatic patients with minimal pneumothorax and for all patients with moderate to large pneumothorax. An opposite position aspiration was performed when simple manual aspiration failed. The efficacy of simple manual aspiration and the opposite position aspiration was observed. Results: Among 210 patients with pneumothorax, 128 (61.0%) asymptomatic patients with minimal pneumothorax were treated conservatively. The remaining 82 were treated with attempted simple manual aspiration. Out of these 82 patients, simple manual aspiration was successful in 58 (70.7%, 58/82) cases. The complete and partial regression rates were 17.2% (10/58) and 82.8% (48/58), respectively. In the other 24 patients (29.3%, 24/82), simple aspiration technique was ineffective. An opposite position (from prone to supine or vice versa) was applied, and a new biopsy puncture site was chosen for reaspiration. This procedure was successful in 22 patients but not in 2 patients who had to have a chest tube insertion. The complete and partial regression rates were 25.0% (6/24) and 66.7% (16/24), respectively. Applying the new method, the total effective rate of aspiration improved significantly from 70.7% (58/82) to 97.6% (80/82). Conclusion: The opposite position aspiration can be safe, effective and minimally invasive treatment for CT-guided lung biopsy-induced pneumothorax thus reducing the use of chest tube significantly. Advances in knowledge: (1) Opposite position aspiration can elevate the success rate of aspiration significantly (from 70.7% to 97

Baptista, Helena; Lopes Cardoso, Inês

Steinert syndrome, also called myotonic dystrophy type 1, is a genetic disorder with autosomal dominant transmission characterized by myotonia and a multisystemic clinical picture that affects several tissues of the human body. The most common systemic phenotypes are: muscular, cardiac, respiratory, CNS, ocular, gynecological, digestive, orthopedical, as well as cognitive and psychological symptoms (cognitive decline). Muscles involved in voluntary movement are highly affected by myotonia especially distal muscles of upper limbs. These patients also show changes in face, chewing and pharynx muscles that can lead to swallowing and speech problems, dysphagia and in most cases to food aspiration and suffocation. Poor oral hygiene resulting from reduced motor mobility and reduced saliva flux can lead to gingival inflammation and periodontal disease. Other oral manifestations include disturbances at the temporomandibular articulation, dental occlusion changes and reduction in teeth number as a result of caries. Main causes of death are pneumonia and cardiac arrhythmias. The etiopathogeny of this syndrome is still not clear, conditioning the existence of a specific treatment for this disease. Nowadays, treatments consist on the release of the existing symptoms, in an attempt to give a better life quality to patients. It is very important to implement actions that can prevent complications and consequently decrease death. Treatments should be applied in an early stage of the disease. Bronchoscopy and artificial respiration should be used to prevent pneumonia, and regular electrocardiographic monitoring should be done to evaluate defects in the conductive system. Several approaches have been applied to rehabilitate swallowing dysfunction and avoid aspiration like videofluoroscopy, postural techniques and adjustment of diet type. It is the aim of this paper to clarify the ethiology, diagnosis, systemic and oral characteristics of the syndrome, as well as to discuss

Refeeding syndrome in a patient with advanced kidney failure due to nephronophthisis.

PubMed

2013-11-01

Refeeding syndrome (RS) is a serious and potentially fatal disorder. It is caused by a shift of fluids, sodium, potassium, magnesium and phosphorus as well changes in the metabolism of glucose, protein, fat and vitamins following the refeeding of malnourished patients, whether enterally or parenterally. RS has rarely been reported in patients with advanced kidney disease probably due to the pre-existing hyperphosphatemia, hypermagnesemia and hyperkalemia in these patients. In the following report, we present a patient with nephronophthisis type 1 deletion syndrome in whom her main previous nutrition was limited to simply rehydration to avoid renal replacement therapy. On presentation, she was cachectic and dehydrated with advanced kidney failure. She was treated with medical nephrectomy using non-steroidal anti-inflammatory drugs and then placed on maintenance hemodialysis. Percutaneous endoscopic gastrostomy was used for her initial feeding. Care was exercised during her early refeeding with regard to correction of fluids and essential electrolytes, viz. potassium, phosphorus and magnesium, as well as multivitamins to avoid the cardiovascular and neurological complications of RS. However, the changes in the gut, pancreas and liver as well as her hyperlipidemia were a clear obstacle. Fortunately, the ileus and pancreatitis she developed on refeeding improved dramatically with a decrease of the feeding dose to half; however, the liver abnormalities and hyperlipidemia were severe and slow to recover. These improved after addition of ursodeoxycholic acid and permitted successful increase of the dose of feeding subsequently.

To test whether thrombus aspiration (TA) reduces the atherosclerotic burden in culprit lesions and "facilitate" percutaneous coronary intervention with stent (S-PCI) among patients with non-ST elevation acute coronary syndromes (NSTE-ACS). Evidence on the effects of TA adjunctive to S-PCI in NSTE-ACS is limited and controversial. TA was defined "aggressive" when using 7F devices or a catheter/artery ratio >0.6, "conservative" with 6F, and a catheter/artery ratio ≤0.6. Angiography and intravascular ultrasound (IVUS) were performed at baseline, after TA and after stent deployment. TA was accomplished in 61/76 patients (80%) with NSTE-ACS. The aspirated material was red thrombus in 23% and plaque fragments in 49% of cases. Compared with baseline, TA was associated with an 82% increase in minimal lumen diameter and a 15% reduction in diameter stenosis (P < 0.001 for both). After TA, IVUS documented a 24 and 16% increase in minimal lumen area and lumen volume, respectively (P < 0.001 for both), a 7% decrease in area stenosis through an 11% reduction of plaque + media volume (P < 0.001). When compared with "conservative", an "aggressive" TA was associated with a more pronounced reduction in percent area stenosis (P < 0.05) and an increase in percent stent expansion (P < 0.001). The plaque + media volume reduction after TA was correlated with stent expansion (r = 0.261, P = 0.046). Manual TA reduces atherothrombotic burden in culprit lesions of NSTE-ACS patients before S-PCI and, when deep plaque removal is obtained, TA optimizes subsequent stent expansion. © 2015 Wiley Periodicals, Inc. © 2015 Wiley Periodicals, Inc.

Neonatal air leak syndrome and the role of high-frequency ventilation in its prevention.

Air leak syndrome includes pulmonary interstitial emphysema, pneumothorax, pneumomediastinum, pneumopericardium, pneumoperitoneum, subcutaneous emphysema, and systemic air embolism. The most common cause of air leak syndrome in neonates is inadequate mechanical ventilation of the fragile and immature lungs. The incidence of air leaks in newborns is inversely related to the birth weight of the infants, especially in very-low-birth-weight and meconium-aspirated infants. When the air leak is asymptomatic and the infant is not mechanically ventilated, there is usually no specific treatment. Emergent needle aspiration and/or tube drainage are necessary in managing tension pneumothorax or pneumopericardium with cardiac tamponade. To prevent air leak syndrome, gentle ventilation with low pressure, low tidal volume, low inspiratory time, high rate, and judicious use of positive end expiratory pressure are the keys to caring for mechanically ventilated infants. Both high-frequency oscillatory ventilation (HFOV) and high-frequency jet ventilation (HFJV) can provide adequate gas exchange using extremely low tidal volume and supraphysiologic rate in neonates with acute pulmonary dysfunction, and they are considered to have the potential to reduce the risks of air leak syndrome in neonates. However, there is still no conclusive evidence that HFOV or HFJV can help to reduce new air leaks in published neonatal clinical trials. In conclusion, neonatal air leaks may present as a thoracic emergency requiring emergent intervention. To prevent air leak syndrome, gentle ventilations are key to caring for ventilated infants. There is insufficient evidence showing the role of HFOV and HFJV in the prevention or reduction of new air leaks in newborn infants, so further investigation will be necessary for future applications.

To evaluate methods of CT-guided sacroiliac joint sampling in patients with suspected infection. All CT-guided sacroiliac joint sampling procedures for suspected infection were reviewed for sampling type (aspiration, lavage aspiration, biopsy), microbiology results, and clinical and imaging follow-up. The primary gold standard was anatomic pathology. If pathology was not available, then positive blood culture with the same organism as SIJ sampling, imaging and clinical follow-up, or clinical follow-up only were used. Anterior and posterior joint distention was evaluated by MRI within 7 days of the procedure. A total of 34 patients (age 39 ± 20 (range, 6-75) years; 21 F, 13 M) were included. Aspiration samples only were obtained in 13/34 (38%) cases, biopsy samples only in 9/34 (26%) cases, and both samples in 12/34 (35%) cases. There was an overall 54% sensitivity and 86% specificity. For the aspiration samples, sensitivity and specificity were 60 and 81%, respectively, compared to 45 and 90% for the biopsy samples. In cases with both samples, biopsy did not add additional microbial information. Seventeen (17/34, 50%) patients had an MRI. The anterior joint was more distended than the posterior joint in 15/17 (88%) of patients, and this difference was significant (P = 0.0003). All of these 17 patients had an attempted aspiration by a posterior approach; 6/17 (35%) resulted in a successful aspiration. Aspiration of the sacroiliac joint has a higher sensitivity than biopsy and should always be attempted first. MRI may be helpful for procedure planning.

Pulse oximetry is a commonly used means to measure peripheral capillary oxyhemoglobin saturation (SpO 2 ). Potential use of pulse oximetry to detect aspiration is attractive to clinicians, as it is readily available, quick, and noninvasive. However, research regarding validity has been mixed. This systematic review examining evidence on the use of pulse oximetry to detect a decrease in SpO 2 indicating aspiration during swallowing is undertaken to further inform clinical practice in dysphagia assessment. A multi-engine electronic search was conducted on 8/25/16 and updated on 4/8/17 in accordance with standards published by the Preferred Reporting for Items for Systematic Reviews and Meta-Analysis Protocols (PRISMA). Inclusion criteria included use of pulse oximetry to detect aspiration with simultaneous confirmation of aspiration via a gold standard instrumental study. Keywords included dysphagia or aspiration AND pulse oximetry. Articles meeting criteria were reviewed by two blinded co-investigators. The search yielded 294 articles, from which 19 were judged pertinent and reviewed in full. Ten met the inclusion criteria and all were rated at Level III-2 on the Australian Diagnostic Levels of Evidence. Study findings were mixed with sensitivity ranging from 10 to 87%. Potentially confounding variables were observed in all studies reviewed, and commonly involved defining "desaturation" within a standard measurement error range (~ 2%), mixed populations, mixed viscosities/textures observed during swallowing, and lack of comparison group. The majority of studies failed to demonstrate an association between observed aspiration and oxygen desaturation. Current evidence does not support the use of pulse oximetry to detect aspiration.

Usher syndrome type 1 due to missense mutations on both CDH23 alleles: investigation of mRNA splicing.

2008-03-01

Usher syndrome (USH) is an autosomal recessive condition characterized by sensorineural hearing loss, vestibular dysfunction, and visual impairment due to retinitis pigmentosa. Truncating mutations in the cadherin-23 gene (CDH23) result in Usher syndrome type 1D (USH1D), whereas missense mutations affecting strongly conserved motifs of the CDH23 protein cause non-syndromic deafness (DFNB12). Four missense mutations constitute an exception from this genotype-phenotype correlation: they have been described in USH1 patients in homozygous state. Using a minigene assay, we have investigated these changes (c.1450G>C, p.A484P; c.3625A>G, p.T1209A; c.4520G>A, p.R1507Q; and c.5237G>A, p.R1746Q) for a possible impact on mRNA splicing which could explain the syndromic phenotype. While in silico analysis suggested impairment of splicing in all four cases, we found aberrant splicing for only one mutation, p.R1746Q. However, splicing was normal in case of p.A484P, p.T1209A and p.R1507Q. These three latter CDH23 missense mutations could interfere with functions of both, the auditory and the visual system. Alternatively, they could represent rare non-pathogenic polymorphisms.

Aspiration-based coevolution of link weight promotes cooperation in the spatial prisoner's dilemma game

PubMed Central

Shen, Chen; Chu, Chen; Shi, Lei

2018-01-01

In this article, we propose an aspiration-based coevolution of link weight, and explore how this set-up affects the evolution of cooperation in the spatial prisoner's dilemma game. In particular, an individual will increase the weight of its link to its neighbours only if the payoff received via this interaction exceeds a pre-defined aspiration. Conversely, if the received payoff is below this aspiration, the link weight with the corresponding neighbour will decrease. Our results show that an appropriate aspiration level leads to a high-cooperation plateau, whereas too high or too low aspiration will impede the evolution of cooperation. We explain these findings with a comprehensive analysis of transition points and with a systematic analysis of typical configuration patterns. The presented results provide further theoretical insights with regards to the impact of different aspiration levels on cooperation in human societies. PMID:29892454

In the clinical setting, there is no reliable tool for diagnosing gastric aspiration. A potential way of diagnosing gastric fluid aspiration entails bronchoalveolar lavage (BAL) with subsequent examination of the BAL fluid for gastric fluid components that are exogenous to the lungs. The objective of this study was to determine the longevity of the gastric fluid components bile and trypsin in the lung, in order to provide an estimate of the time frame in which assessment of these components in the BAL might effectively be used as a measure of aspiration. Human gastric fluid (0.5 mg/kg) was infused in the right lung of intubated male Fischer 344 rats (n = 30). Animals were sacrificed at specified times following the experimentally induced aspiration, and bronchoalveolar lavage fluid (BALF) was collected. Bile concentrations were analyzed by an enzyme-linked chromatogenic method, and the concentration of trypsin was quantified using an ELISA. Data were analyzed using non-linear regression and a one-phase decay equation. In this experimental model, the half-life of bile was 9.3 hours (r(2) = 0.81), and the half-life of trypsin was 9.0 hours (r(2) = 0.68). The half-lives of bile and trypsin in the rodent aspiration model suggest that the ability to detect aspiration may be limited to a few days post-aspiration. If studies using rats are any indication, it may be most effective to collect BAL samples within the first 24 hours of suspected aspiration events in order to detect aspiration.

Promotion of cooperation induced by appropriate payoff aspirations in a small-world networked game

Based on learning theory, we adopt a stochastic learning updating rule to investigate the evolution of cooperation in the Prisoner’s Dilemma game on Newman-Watts small-world networks with different payoff aspiration levels. Interestingly, simulation results show that the mechanism of intermediate aspiration promoting cooperation resembles a resonancelike behavior, and there exists a ping-pong vibration of cooperation for large payoff aspiration. To explain the nontrivial dependence of the cooperation level on the aspiration level, we investigate the fractions of links, provide analytical results of the cooperation level, and find that the simulation results are in close agreement with analytical ones. Our work may be helpful in understanding the cooperative behavior induced by the aspiration level in society.

Cooperation guided by the coexistence of imitation dynamics and aspiration dynamics in structured populations

Xu, Kuangyi; Li, Kun; Cong, Rui; Wang, Long

2017-02-01

In the framework of the evolutionary game theory, two fundamentally different mechanisms, the imitation process and the aspiration-driven dynamics, can be adopted by players to update their strategies. In the former case, individuals imitate the strategy of a more successful peer, while in the latter case individuals change their strategies based on a comparison of payoffs they collect in the game to their own aspiration levels. Here we explore how cooperation evolves for the coexistence of these two dynamics. Intriguingly, cooperation reaches its lowest level when a certain moderate fraction of individuals pick aspiration-level-driven rule while the others choose pairwise comparison rule. Furthermore, when individuals can adjust their update rules besides their strategies, either imitation dynamics or aspiration-driven dynamics will finally take over the entire population, and the stationary cooperation level is determined by the outcome of competition between these two dynamics. We find that appropriate synergetic effects and moderate aspiration level boost the fixation probability of aspiration-driven dynamics most effectively. Our work may be helpful in understanding the cooperative behavior induced by the coexistence of imitation dynamics and aspiration dynamics in the society.

Aspergillus are ubiquitous and more than 30 species have been reported to be involved in human infection. Most of the cases occur in immunocompromised patients and are disseminated in the blood. Primary cutaneous aspergillosis in immunocompetent hosts is rare. We report a unique case of primary cutaneous aspergillosis in an immunocompetent patient diagnosed by fine needle aspiration cytology. The characteristic ascocarp and ascospores of Aspergillus species were found in the aspirate and Aspergillus glaucus was isolated in pure culture. The case is presented to increase the awareness of the usefulness of fine needle aspiration cytology for diagnosing fungal infections. PMID:24371752

This study investigated the novel associations between intrinsic and extrinsic aspirations and internal and external domains of contingent self-worth among a sample of 502 Iranian university students. We found a meaningful pattern showing that intrinsic aspirations were positively associated with internal domains, whereas extrinsic aspirations were positively associated with external domains. Our survey data also suggested that the factor structure of the Aspiration Index, as well as the factor structure of the Contingencies of Self-Worth Scale in our Iranian sample were consistent with factor structures of foreign samples. Finally, the types of aspirations and domains of contingencies of self-worth meaningfully predicted variables related to well-being, confirming previous research. We discuss the nature of the associations between the aspirations and the domains of contingent self-worth.

Recurrent laryngeal nerve reinnervation for management of aspiration in a subset of children.

PubMed

Zur, Karen B; Carroll, Linda M

2018-01-01

Pediatric aspiration is a multifactorial process that is often complex to manage. Recurrent laryngeal nerve (RLN) injury can cause glottic insufficiency and aspiration. We describe three cases of unilateral vocal fold paralysis resulting in aspiration and the successful use of the RLN reinnervation for its treatment. The theory for utilizing the reinnervation procedure is that when glottic closure improves and a less breathy vocalization occurs, then the larynx is better equipped to protect the lower airway and avoid aspiration. Our cases demonstrate stronger voice and improved swallow function, with normalization of modified barium swallow evaluation, at approximately 6-months post reinnervation. Copyright © 2017.

To assess the usefulness of aspiration sclerotherapy in the treatment of hydroceles in the tropics. This prospective study included 82 patients with 94 primary vaginal hydroceles of which 62 hydroceles were treated by aspiration and tetracycline hydrochloride sclerotherapy as an outpatient procedure (mean age of patients 56.5 years, range 40-82) and 28 were treated surgically and included as controls (mean age 52.4 years, range 40-70). All patients were followed for a year. In the sclerotherapy group, the overall cure rate after a year was 95%. Few complications were encountered in this group: six patients (10%) experienced pain during the procedure, seven patients (12%) had local infection and three patients (5%) developed haematoma. No recurrence was encountered in the surgical group, seven patients (25%) had infection and two patients (7%) developed haematoma. The mean hospital stay for the surgical group was 3.4 +/- 1.3 days (range 1-7). Four patients with thick-walled hydroceles had persistent swelling after sclerotherapy, the recurrence of which dissatisfied the patients. Aspiration sclerotherapy for thin-walled hydroceles proved to be a curative, simple, safe and cost-effective out-patient procedure. It can be an alternative to surgery in developing countries where resources are limited.

There has been an increase in the use of fine needle aspiration cytology (FNAC) for the diagnosis of parathyroid lesions (PLs). Differentiation between a thyroid lesion and a PL is not easy because of their similar features. We reviewed parathyroid aspirates in our institution and aimed to uncover trends in diagnostic criteria. We selected 25 parathyroid aspirates (from 6 men and 19 women) confirmed surgically or immunohistochemically from 2006 to 2011. Major architectural findings of PLs include scattered naked nuclei, loose clusters, a papillary pattern with a fibrovascular core, tight clusters, and a follicular pattern. These architectures were commonly admixed with one another. Cytological features included anisokaryosis, stippled chromatin, a well-defined cell border, and oxyphilic cytoplasm. Eighteen of the 25 patients were diagnosed with PL using FNAC. Seven patients had been misdiagnosed with atypical cells (n=2), benign follicular cells (n=2), adenomatous goiter (n=2) and metastatic carcinoma (n=1) in FNAC. Using clinicoradiologic data, the sensitivity of the cytological diagnosis was 86.7%. The cytological sensitivity decreased to 50% without this information. FNAC of PL is easily confused with thyroid lesions. A combination of cytological parameters and clinical data will be required to improve the diagnostic sensitivity of PLs.

Congenital myasthenic syndromes (CMS) are neuromuscular transmission disorders caused by mutations in genes encoding neuromuscular junction proteins. CMS due to choline acetyltransferase (CHAT) gene is characterized by episodic apnea. We report a case of a 12-month-old female patient presented with recurrent episodic apnea carrying a mutation in CHAT gene, p.I336T. Furthermore, we describe the genetic and clinical findings in 44 CMS patients due to CHAT mutations in the literature up to date. Episodes of apnea and respiratory insufficiency are the hallmarks of CHAT mutations. Clinical manifestations usually provoked by infections and fever. CMS due to CHAT mutations are rare, but it is important to diagnosis. Early diagnosis and appropriate treatment can improve morbidity and mortality. Georg Thieme Verlag KG Stuttgart · New York.

Purpose This paper aims to test a model examining precursors and outcomes of nurses' leadership self-efficacy, and their aspirations to management positions. Design/methodology/approach A cross-sectional survey of 727 registered nurses across Canada was conducted. Structural equation modelling using Mplus was used to analyse the data. Findings Results supported the hypothesized model: χ 2 (312) = 949.393; CFI = 0.927; TLI = 0.919; RMSEA = 0.053 (0.049-0.057); SRMR 0.044. Skill development opportunities ( ß = 0.20), temporary management roles ( ß = 0.12) and informal mentoring ( ß = 0.11) were significantly related to nurses' leadership self-efficacy, which significantly influenced motivation to lead ( ß = 0.77) and leadership career aspirations ( ß = 0.23). Motivation to lead was significantly related to leadership career aspirations ( ß = 0.50). Practical implications Nurses' leadership self-efficacy is an important determinant of their motivation and intention to pursue a leadership career. Results suggest that nurses' leadership self-efficacy can be influenced by providing opportunities for leadership mastery experiences and mentorship support. Leadership succession planning should include strategies to enhance nurses' leadership self-efficacy and increase front-line nurses' interest in leadership roles. Originality value With an aging nurse leader workforce, it is important to understand factors influencing nurses' leadership aspirations to develop and sustain nursing leadership capacity. This research study makes an important contribution to the nursing literature by showing that nurses' leadership self-efficacy appears to be an important determinant of their motivation to lead and desire to pursue a career as a nurse leader.

Wolfram's syndrome is a rare neurodegenerative disorder, which usually first manifests itself around the age of 6 years. The diagnosis can be made based on the characteristics incorporated in the 'DIDMOAD' acronym: diabetes insipidus, diabetes mellitus, optic atrophy and deafness. We present 2 boys, diagnosed with diabetes mellitus at the age of 5 and 4 years respectively. Both children developed optic atrophy over the years. These 2 cases illustrate that alongside diabetic retinopathy, possible syndromes, such as Wolfram's syndrome, should also be considered in children with diabetes mellitus and visual impairment.

Background Leigh syndrome is an early onset, progressive, neurodegenerative disorder with developmental and motor skills regression. Characteristic magnetic resonance imaging abnormalities consist of focal bilateral lesions in the basal ganglia and/or the brainstem. The main cause is a deficiency in oxidative phosphorylation due to mutations in an mtDNA or nuclear oxidative phosphorylation gene. Methods and results A consanguineous Moroccan family with Leigh syndrome comprise 11 children, three of which are affected. Marker analysis revealed a homozygous region of 11.5 Mb on chromosome 20, containing 111 genes. Eight possible mitochondrial candidate genes were sequenced. Patients were homozygous for an unclassified variant (p.P193L) in the cardiolipin synthase gene (CRLS1). As this variant was present in 20% of a Moroccan control population and enzyme activity was only reduced to 50%, this could not explain the rare clinical phenotype in our family. Patients were also homozygous for an amino acid substitution (p.L159F) in C20orf7, a new complex I assembly factor. Parents were heterozygous and unaffected sibs heterozygous or homozygous wild type. The mutation affects the predicted S-adenosylmethionine (SAM) dependent methyltransferase domain of C20orf7, possibly involved in methylation of NDUFB3 during the assembly process. Blue native gel electrophoresis showed an altered complex I assembly with only 30–40% of mature complex I present in patients and 70–90% in carriers. Conclusions A new cause of Leigh syndrome can be a defect in early complex I assembly due to C20orf7 mutations. PMID:19542079

Overgrowth syndromes (OGS) are a group of disorders in which all parameters of growth and physical development are above the mean for age and sex. We evaluated a series of 270 families from the Spanish Overgrowth Syndrome Registry with no known OGS. We identified one de novo deletion and three missense mutations in RNF125 in six patients from four families with overgrowth, macrocephaly, intellectual disability, mild hydrocephaly, hypoglycemia, and inflammatory diseases resembling Sjögren syndrome. RNF125 encodes an E3 ubiquitin ligase and is a novel gene of OGS. Our studies of the RNF125 pathway point to upregulation of RIG-I-IPS1-MDA5 and/or disruption of the PI3K-AKT and interferon signaling pathways as the putative final effectors. © 2014 WILEY PERIODICALS, INC.

Efficacy of Thickened Liquids for Eliminating Aspiration in Head and Neck Cancer: A Systematic Review

2015-01-01

Objective To appraise the current videofluoroscopic evidence on the reduction of aspiration using thickened liquids in the head and neck cancer population. Data Sources Search terms relating to deglutition or dysphagia or swallow and neoplasms and oncology or head and neck cancer and viscosity or texture and apira or residu* were combined with honey or nectar, xerostomia, respiratory aspiration using Boolean operators. Review Methods A multi-engine literature search identified 337 non-duplicate articles of which 6 were judged to be relevant. These underwent detailed review for study quality and qualitative synthesis. Results The articles reviewed in detail predominantly described heterogeneous study samples with small sample sizes, making for difficult interpretation and generalization of results. Rates of aspiration were typically not reported by bolus consistency, despite the fact that a variety of stimulus consistencies was used during VFSS. Studies confirmed that aspiration is a major concern in the head and neck cancer population and reported a trend towards more frequent aspiration post-(chemo)radiotherapy. Conclusion Overall, the literature on thickened liquids as an intervention to eliminate aspiration in the head and neck cancer population is limited. Because aspiration is known to be prevalent in the head and neck cancer population and thickened liquids are known to eliminate aspiration in other populations, it is important to determine the effectiveness of thickened liquids for reducing aspiration in the head and neck cancer population.

Background Dysphagia is one of the most dangerous symptoms of acute stroke. Various screening tools have been suggested for the early detection of this condition. In spite of conflicting results, measurement of oxygen saturation (SpO2) during clinical swallowing assessment is still recommended by different national guidelines as a screening tool with a decline in SpO2 ≥2% usually being regarded as a marker of aspiration. This paper assesses the sensitivity of SpO2 measurements for the evaluation of aspiration risk in acute stroke patients. Methods Fifty acute stroke patients with moderate to severe dysphagia were included in this study. In all patients, fiberoptic endoscopic evaluation of swallowing (FEES) was performed according to a standardised protocol. Blinded to the results of FEES, SpO2 was monitored simultaneously. The degree of desaturation during/after swallows with aspiration was compared to the degree of desaturation during/after swallows without aspiration in a swallow-to-swallow analysis of each patient. To minimise potential confounders, every patient served as their control. Results In each subject, a swallow with and a swallow without aspiration were analysed. Overall, aspiration seen in FEES was related to a minor decline in SpO2 (mean SpO2 without aspiration 95.54 ± 2.7% vs. mean SpO2 with aspiration 95.28 ± 2.7%). However, a significant desaturation ≥2% occurred only in 5 patients during/after aspiration. There was no correlation between aspiration/dysphagia severity or the amount of aspirated material and SpO2 levels. Conclusions According to this study, measurement of oxygen desaturation is not a suitable screening tool for the detection of aspiration in stroke patients. PMID:28259883

Non-mosaic Klinefelter patients are generally azoospermic due to primary testicular failure. Nevertheless, in some cases, testicular spermatozoa may be recovered and utilized to fertilize oocytes via intracytoplasmic sperm injection (ICSI). As the risk for an increased number of gonosomes in these spermatozoa is unclear, preimplantation genetic diagnosis (PGD) may be attempted in the resulting embryos. In the present study, we report our experience with the combined approach of sperm retrieval by testicular fine needle aspiration (FNA), ICSI and PGD in seven consecutive non-mosaic Klinefelter individuals. In four patients, between one and five spermatozoa were retrieved in five out of nine consecutive attempts. In a fifth patient, only 10 round spermatids could be isolated. Mature spermatozoa were injected into a total of 16 metaphase-II oocytes, of which 11 (69%) remained intact. Two distinct pronuclei (2PN) were observed in four oocytes (36%) while a single pronucleus (1PN) was documented in two oocytes. Five cleavage stage embryos developed from the oocytes of two couples. Upon the request of one couple, their three embryos (two derived from 1PN oocytes) were transferred without PGD but pregnancy was not achieved. PGD by fluorescence in-situ hybridization (FISH) was performed in the two embryos of the other couple which were derived from normal fertilization. PGD results of one embryo were 18,18,X,X,Y, the embryo was not transferred and FISH analysis of the remaining blastomeres identified variable chromosome numbers in the nuclei. The second embryo was diagnosed as normal and was transferred, resulting in a successful pregnancy and birth. In conclusion, the results of this report indicate that a pregnancy and birth may be attained in azoospermic non-mosaic Klinefelter individuals by testicular FNA combined with ICSI. Due to the unknown risk of gonosomes aneuploidy in embryos from Klinefelter patients, PGD or prenatal diagnosis should be recommended.

The objective was to evaluate if existence of hydrothorax in initial chest radiograph predicts treatment outcome in patients with primary spontaneous pneumothorax who received needle thoracostomy. This is a retrospective cohort study carried out from January 2011 to August 2014 in 1 public hospital in Hong Kong. All consecutive adult patients aged 18years or above who attended the emergency department with the diagnosis of primary spontaneous pneumothorax with needle aspiration performed as primary treatment were included. Age, smoking status, size of pneumothorax, previous history of pneumothorax, aspirated gas volume and presence of hydropneumothorax in initial radiograph were included in the analysis. The outcome was success or failure of the needle aspiration. Logistic regression was used to identify the predicting factors of failure of needle aspiration. There were a total of 127 patients included. Seventy-three patients (57.5%) were successfully treated with no recurrence upon discharge. Among 54 failure cases, 13 patients (10.2%) failed immediately after procedure as evident by chest radiograph and required second treatment. Forty-one patients (32.3%) failed upon subsequent chest radiographs. Multivariate logistic regression showed factors independently associated with the failure of needle aspiration, which included hydropneumothorax in the initial radiograph (odds ratio [OR]=4.47 [1.56i12.83], P=.005), previous history of pneumothorax (OR=3.92 [1.57-9.79], P=.003), and large size of pneumothorax defined as apex-to-cupola distance ≥5cm (OR=2.75 [1.21-6.26], P=.016). Hydropneumothorax, previous history of pneumothorax, and large size were independent predictors of failure of needle aspiration in treatment of primary spontaneous pneumothorax.

Experimental Investigation of a High Pressure Ratio Aspirated Fan Stage

NASA Technical Reports Server (NTRS)

Merchant, Ali; Kerrebrock, Jack L.; Adamczyk, John J.; Braunscheidel, Edward

2004-01-01

The experimental investigation of an aspirated fan stage designed to achieve a pressure ratio of 3.4:1 at 1500 ft/sec is presented in this paper. The low-energy viscous flow is aspirated from diffusion-limiting locations on the blades and flowpath surfaces of the stage, enabling a very high pressure ratio to be achieved in a single stage. The fan stage performance was mapped at various operating speeds from choke to stall in a compressor facility at fully simulated engine conditions. The experimentally determined stage performance, in terms of pressure ratio and corresponding inlet mass flow rate, was found to be in good agreement with the three-dimensional viscous computational prediction, and in turn close to the design intent. Stage pressure ratios exceeding 3:1 were achieved at design speed, with an aspiration flow fraction of 3.5 percent of the stage inlet mass flow. The experimental performance of the stage at various operating conditions, including detailed flowfield measurements, are presented and discussed in the context of the computational analyses. The sensitivity of the stage performance and operability to reduced aspiration flow rates at design and off design conditions are also discussed.

Loss of protective airway reflexes in patients with acute coma puts these patients at risk of aspiration pneumonia complicating the course of the primary disease. Available data vary considerably with regard to bacteriology, role of anaerobic bacteria, and antibiotic treatment. Our objective was to research the bacteriology of aspiration pneumonia in acute coma patients who were not pre-treated with antibiotics or hospitalized within 30 days prior to the event. We prospectively analyzed 127 patient records from adult patients admitted, intubated and ventilated to a tertiary medical intensive care unit with acute coma. Bacteriology and antibiotic resistance testing from tracheal aspirate sampled within 24 h after admission, blood cultures, ICU scores (APACHE II, SOFA), hematology, and clinical chemistry were assessed. Patients were followed up until death or hospital discharge. The majority of patients with acute coma suffered from acute cardiovascular disorders, predominantly myocardial infarction, followed by poisonings, and coma of unknown cause. In a majority of our patients, microaspiration resulted in overt infection. Most frequently S. aureus, H. influenzae, and S. pneumoniae were isolated. Anaerobic bacteria (Bacteroides spec., Fusobacteria, Prevotella spec.) were isolated from tracheal aspirate in a minority of patients, and predominantly as part of a mixed infection. Antibiotic monotherapy with a 2nd generation cephalosporin, or a 3rd generation gyrase inhibitor, was most effective in our patients regardless of the presence of anaerobic bacteria.

Leigh syndrome, which is a common phenotype of pediatric mitochondrial disease, is a progressive neurodegenerative disease. The typical neuroimaging findings of Leigh syndrome include bilateral symmetric lesions in the basal ganglia and/or the brainstem. However, there are a few reports on spinal cord involvement in patients with Leigh syndrome. In the present case, magnetic resonance imaging (MRI) obtained during infancy revealed symmetric lesions in the substantia nigra of a patient with Leigh syndrome with an NDUFA1 mutation; lesions of the bilateral putamen and brainstem were subsequently observed. Additionally, our patient presented large and extended spinal cord lesions. Therefore, this case is suggesting that we should consider the occurrence of spinal cord lesions as an atypical finding in Leigh syndrome. Copyright © 2018 The Japanese Society of Child Neurology.

Transbronchial needle aspiration (TBNA) of small lesions or lymph nodes in the lung may result in nondiagnostic tissue samples. We demonstrate the integration of an optical coherence tomography (OCT) probe into a 19-gauge flexible needle for lung tissue aspiration. This probe allows simultaneous visualization and aspiration of the tissue. By eliminating the need for insertion and withdrawal of a separate imaging probe, this integrated design minimizes the risk of dislodging the needle from the lesion prior to aspiration and may facilitate more accurate placement of the needle. Results from in situ imaging in a sheep lung show clear distinction between solid tissue and two typical constituents of nondiagnostic samples (adipose and lung parenchyma). Clinical translation of this OCT-guided aspiration needle holds promise for improving the diagnostic yield of TBNA.

1991-12-01

The aim of the present study was to determine the diagnostic accuracy of different modes of fine needle aspiration (FNA) of liver lesions. A total of 492 FNAs were performed on 406 patients in order to confirm or to rule out focal or multifocal neoplastic disease: 29% under ultrasound (US) guidance, 3% with computed tomographic (CT) guidance, 67% preoperatively, and 1% intraoperatively without imaging guidance. Based on histologic, cytologic, and clinical findings, final diagnoses were reached in 387 patients, of whom 264 had malignant liver disease and 123 had benign liver disease. Of 321 aspirations performed in patients with malignant liver disease, the cytologic findings suggested malignancy in 225 (70.1%), suspected malignancy in 25 (7.8%), and did not reveal malignancy in 71 aspirations (22.1%). Among the 123 patients with benign liver disease, the cytologic findings were reported as benign in all but two patients, who had false-positive cytologic findings. The overall sensitivity, specificity, positive, and negative predictive values for cytologic findings were 85.6, 98.4, 99.1, and 76.1%, respectively. The overall diagnostic accuracy was 89.7%. In one patient, fatal intraperitoneal bleeding due to chronic intravascular coagulation complicated the FNA procedure. We conclude that imaging-guided FNA as well as nonguided FNA for cytologic diagnosis of liver lesions are highly accurate and only rarely may be associated with a fatal complication.

Toxoplasma lymphadenitis diagnosed by fine-needle aspiration cytology: a rare finding.

There are only very few reports of cervical toxoplasma lymphadenitis being diagnosed exclusively via fine-needle aspiration cytology (with serology). We describe a case of toxoplasma lymphadenitis that was successfully diagnosed by fine-needle aspiration cytology. The case involved a male patient who was immunocompromised as a result of recurrent acute myelogenous leukaemia with cervical lymphadenopathy. The biopsy showed typical features of a well-defined pseudocyst containing Toxoplasma gondii tachyzoites. Toxoplasma lymphadenitis is a common cause of lymph node enlargement. Fine-needle aspiration cytology is a useful method for diagnosing and differentiating toxoplasma lymphadenitis from more serious causes of lymphadenopathy, such as metastatic lymphadenopathy or lymphoma.

OBJECTIVES: Our clinical experience suggested that elemental diets were associated with a reduction in aspiration pneumonia among bedridden patients with percutaneous endoscopic gastrostomy (PEG). We compared the effects of elemental and standard liquid diets on the risk of clinical aspiration pneumonia and gastric emptying in bedridden patients receiving PEG feedings. METHODS: Study 1: consecutive bedridden PEG patients received elemental diets or standard liquid diets in the same fashion. The frequency of defecation, diet aspirated from the trachea, and aspiration pneumonia during hospitalization were prospectively recorded. Study 2: a randomized, crossover trial using elemental or standard liquid diets containing 13C sodium acetate as a tracer given to bedridden PEG patients who had experienced aspiration pneumonia. 13C breath tests were performed to estimate gastric emptying. RESULTS: Study 1: 127 patients were enrolled, 60 with elemental and 67 with standard liquid diets. The diet was aspirated from the trachea in none (0%) with the elemental diet vs. 8 (11.9%) with standard liquid diets (P=0.0057); aspiration pneumonia developed none with the elemental diet vs. 5 (7.5%) with standard liquid diets (P=0.031) (number needed to treat 14, 95% confidence interval 7–85). Study 2: 19 patients were enrolled. The elemental diet was associated with a significant increase in the 10, 30 or 50% emptying (excretion) time (P<0.001) and increased the area under the curve (% dose/h) compared with the standard liquid diet (P<0.05). CONCLUSIONS: Elemental diets were associated with more rapid gastric empting and fewer episodes of aspiration than standard liquid diets in bedridden PEG patients. They may be preferred for bedridden PEG patients especially who have experienced aspiration pneumonia. Properly performed randomized-controlled trials are needed to prove this potential benefit.

Metastatic brain tumors over 3 cm in diameter (volume of 14.1ml) are generally considered poor candidates for Gamma Knife surgery (GKS). We retrospectively assessed the method and efficacy of GKS for large cystic metastatic brain tumors after navigation-guided aspiration under local anesthesia. From September 2007 to April 2014, 38 cystic metastatic brain tumors in 32 patients (12 males, 20 females; mean age, 63.2 years) were treated at Kansai Rosai Hospital. The patients were performed navigation-guided cyst aspiration under local anesthesia, then at the day or the next day, were performed GKS and usually discharged on the day. The methods for preventing of leptomeningeal dissemination are following: 1) puncture from the place whose cerebral thickness is 1 cm or more; 2) avoidance of Ommaya reservoir implantation; and 3) placement of absorbable gelatin sponge to the tap tract. Tumor volume, including the cystic component, decreased from 25.4 ml (range 8.7-84.7 ml) to 11.4 ml (range 2.9-36.7 ml) following aspiration; the volume reduction was approximately 51.6%. Follow-up periods in the study population ranged from 0 to 24 months (median 3.5 months). The overall median survival was 6.7 months. There was no leptomeningeal dissemination related to the aspiration. One patient experienced radiation necrosis after GKS, one patient experienced re-aspiration by failure of aspiration, and two patients experienced surgical resections and one patient experienced re-aspiration by cyst regrowth after GKS. Long-term hospitalization is not desirable for the patients with brain metastases. In japan, Long-term hospitalization is required for surgical resection or whole brain radiation therapy, but only two days hospitalization is required for GKS after navigation-guided aspiration at our hospital. This GKS after navigation-guided aspiration is more effective and less invasive than surgical resection or whole brain radiation therapy.

Takotsubo syndrome is characterized by predominantly medial-apical transient left ventricular dysfunction, which is typically triggered by physical or emotional stress. The present article reports the case of a 61-year-old female patient presenting with dizziness, excessive sweating, and sudden state of ill feeling following an episode involving intense emotional stress. The physical examination and electrocardiogram were normal upon admission, but the troponin I and creatine kinase-MB concentrations were increased. Acute myocardial infarction without ST segment elevation was suspected, and coronary angiography was immediately performed, which showed severe diffuse left ventricular hypokinesia, medial-apical systolic ballooning, and a lack of significant coronary injury. The patient was referred to the intensive care unit and was successfully treated with supportive therapy. As this case shows, Takotsubo syndrome might simulate the clinical manifestations of acute myocardial infarction, and coronary angiography is necessary to distinguish between both myocardial infarction and myocardial infarction in the acute stage. The present patient progressed with spontaneous resolution of the ventricular dysfunction without any sequelae.

2013-04-01

To measure the efficiency of phacoemulsification, we have developed a new experimental model for testing phaco-efficiency and analyzed re-aspiration of repulsed particles. Using a Kitaro wetlab system, a piece of blood agar (BA) was placed in an artificial chamber and the phacoemulsifier was placed horizontally. The settings of the phacoemulsifier (Infiniti, Alcon Laboratories) were 26 cc/min for aspiration, 350 cc/min for vacuum, and 95 cm of bottle height. The time to remove BAs was measured using Ozil 100 %, Ozil 40 %, and longitudinal 40 % of phaco power. The angle between the re-aspirated BA particles and the axis of the phacoemulsifier (re-aspiration zone, degree) was analyzed. The average time (seconds) to remove BAs was lower in the Ozil 100 % and the Ozil 40 % mode than in the longitudinal mode (0.37 ± 0.39, 0.85 ± 0.57, and 2.22 ± 1.40 respectively, P value < 0.01). Repulsion exceeding 1 mm occurred more frequently in the longitudinal mode than in the Ozil 100 % mode (100 % vs 40 %, P value = 0.01, Fisher's exact test). The average of re-aspiration zone was 25.9 ± 14.5 in the longitudinal 40 % and 54.0 ± 23.0 in the Ozil 40 % (P value = 0.016). The Ozil mode was more efficient than the longitudinal mode. In addition, the Ozil mode provided less repulsion and wider aspiration zone.

Foreign body aspiration and language spoken at home: 10-year review.

To review foreign body aspiration cases encountered over a 10-year period in a tertiary paediatric hospital, and to assess correlation between foreign body type and language spoken at home. Retrospective chart review of all children undergoing direct laryngobronchoscopy for foreign body aspiration over a 10-year period. Age, sex, foreign body type, complications, hospital stay and home language were analysed. At direct laryngobronchoscopy, 132 children had foreign body aspiration (male:female ratio 1.31:1; mean age 32 months (2.67 years)). Mean hospital stay was 2.0 days. Foreign bodies most commonly comprised food matter (53/132; 40.1 per cent), followed by non-food matter (44/132; 33.33 per cent), a negative endoscopy (11/132; 8.33 per cent) and unknown composition (24/132; 18.2 per cent). Most parents spoke English (92/132, 69.7 per cent; vs non-English-speaking 40/132, 30.3 per cent), but non-English-speaking patients had disproportionately more food foreign bodies, and significantly more nut aspirations (p = 0.0065). Results constitute level 2b evidence. Patients from non-English speaking backgrounds had a significantly higher incidence of food (particularly nut) aspiration. Awareness-raising and public education is needed in relevant communities to prevent certain foods, particularly nuts, being given to children too young to chew and swallow them adequately.

Pearson syndrome (PS) is a rare multisystem mitochondrial disorder of hematopoietic system, characterized by refractory sideroblastic anemia, pancytopenia, exocrine pancreatic insufficiency, and variable neurologic, hepatic, renal, and endocrine failure. We describe a six-month-old female infant with Pearson marrow syndrome who presented with neurological manifestations. She had several episodes of seizures. Hematopoietic abnormalities were macrocytic anemia and neutropenia. Bone marrow aspiration revealed a cellular marrow with marked vacuolization of erythroid and myeloid precursors. Analysis of mtDNA in peripheral blood showed 8.5 kb deletion that was compatible with the diagnosis of PS. PS should be considered in infants with neurologic diseases, in patients with cytopenias, and also in patients with acidosis or refractory anemia.

Dubin-Johnson syndrome is a chronic, benign, intermittent jaundice, mostly of conjugated hyperbilirubinemia. The level of bilirubin is not expected to be more than 20 mg/dl in this syndrome. In this article, we report a patient who was evaluated for hyperbilirubinemia and liver function test abnormalities and diagnosed with Dubin-Johnson syndrome coexisting with hereditary spherocytosis. We suggest that other diseases should be investigated if patients with Dubin-Johnson syndrome present with severe hyperbilirubinemia. Dubin-Johnson syndrome accompanied by hemolytic diseases might also have high coproporphyrin levels (as in Rotor's syndrome) than expected in pure Dubin-Johnson syndrome.

We aimed to present a clinical case of a patient with Alport syndrome with spontaneous anterior lens capsule rupture. A 16-year-old male with histologically proven Alport syndrome was hospitalised in the Department of Ophthalmology, University Hospital "Prof. Stoyan Kirkovich", Stara Zagora with low vision, pain, redness, high IOP and rupture of the anterior lenticular capsule of the right eye. Phacoaspiration was successfully performed (Millenium, Bausch& Lomb, Rochester, New York, USA) with the bimanual irrigation-aspiration system (Geuder AG, Heidelberg, Germany) with excellent visual results. As the syndrome is quite rare and can lead to diagnostic difficulties for the ophthalmologist complications such as spontaneous or traumatic rupture of the capsule are not uncommon. In such cases, phacoaspiration is an efficient method for clear lens extraction after ruptures of the anterior lenticular capsule of young patients with Alport syndrome.

We retrospectively investigated the diagnostic accuracy and complication rate of transthoracic core biopsy using an automated biopsy gun and compared the findings with those of aspiration needle biopsy. Seventy-three patients underwent 74 core biopsy procedures and 50 patients underwent 52 aspiration biopsy procedures. Of these, a final diagnosis was obtained in 107 lesions with surgery or clinical course. Fifteen patients in which a final diagnosis was not obtained were excluded from the study on diagnostic accuracy. Thus, in the study of diagnostic accuracy, 63 core biopsy procedures for 62 lesions are included. Core biopsy was performed with an 18 G cutting needle using an automated biopsy gun. Aspiration biopsy was performed with a 20 G aspiration needle. Core biopsy yielded sufficient material in 57/63 procedures (90.5%). A correct diagnosis was obtained in 36 procedures (85.7%) for malignant leisons and a specific benign diagnosis was obtained in 11 procedures (52.4%). Aspiration biopsy yielded a correct diagnosis in 26 procedures (81.3%) for malignant leisons and in seven (46.7%) for benign lesions. The overall correct diagnosis were 75.8% and 71.7% with core biopsy and aspiration biopsy, respectively. Core biopsy gave a higher predictive rate than that of aspiration biopsy for both benign and malignant lessons (P < 0.02). Pneumothorax occurred in 18/74 (24.3%) patients with core biopsy and in 18/45 (40.0%) patients with aspiration biopsy. Of these, three with core biopsy and two with aspiration biopsy needed tube drainage. The other complication was haemoptysis, which occurred in six patients following core biopsy and in three after aspiration biopsy. All nine cases subsided spontaneously. There were no fatal complications. Core biopsy with a biopsy gun increase the diagnostic accuracy with a higher histologic predictive rate and no obvious additional risk of complications.

Pneumothorax occurs more frequently in the neonatal period than at any other time of life and is associated with increased mortality and morbidity. It may be treated with either needle aspiration or insertion of a chest tube. The former consists of aspiration of air with a syringe through a needle or an angiocatheter, usually through the second or third intercostal space in the midclavicular line. The chest tube is usually placed in the anterior pleural space passing through the sixth intercostal space into the pleural opening, turned anteriorly and directed to the location of the pneumothorax, and then connected to a Heimlich valve or an underwater seal with continuous suction. To compare the efficacy and safety of needle aspiration and intercostal tube drainage in the management of neonatal pneumothorax. We used the standard search strategy of the Cochrane Neonatal Review group to search the Cochrane Central Register of Controlled Trials (CENTRAL 2015, Issue 11), MEDLINE via PubMed (1966 to 30 November 2015), EMBASE (1980 to 30 November 2015), and CINAHL (1982 to 30 November 2015). We also searched clinical trials databases, conference proceedings, and the reference lists of retrieved articles for randomised controlled trials and quasi-randomised trials. Randomised controlled trials, quasi-randomised controlled trials and cluster trials comparing needle aspiration (either with the needle or angiocatheter left in situ or removed immediately after aspiration) to intercostal tube drainage in newborn infants with pneumothorax. For each of the included trial, two authors independently extracted data (e.g. number of participants, birth weight, gestational age, kind of needle and chest tube, choice of intercostal space, pressure and device for drainage) and assessed the risk of bias (e.g. adequacy of randomisation, blinding, completeness of follow-up). The primary outcomes considered in this review are mortality during the neonatal period and during hospitalisation. One

The objective of this retrospective review is to evaluate the ability of the Murray secretion scale to predict aspiration as determined by fiberoptic endoscopic evaluation of swallowing. Patients with dysphagia undergoing a fiberoptic endoscopic evaluation of swallowing study between January 2013 and November 2015 from a single, tertiary care institution were retrospectively reviewed. The Murray secretion scale and penetration aspiration scale on fiberoptic endoscopic evaluation of swallowing examination were determined. Spearman's correlation analysis, sensitivity, specificity, predictive values, and relative risk evaluating the relationship between the Murray secretion scale and aspiration on fiberoptic endoscopic evaluation of swallowing were calculated. Subgroups of head and neck cancer patients, penetration group, and aspiration group were also analyzed. The mean age of the cases (N = 212) was 62.4 years. Eighty percent were male. There was a strong correlation between Murray secretion scale grade and penetration aspiration scale score (r = 0.785, p < 0.001). The sensitivity and specificity of a Murray secretion scale grade 2 or higher in predicting aspiration were 74 and 90%, respectively. Individuals with a Murray secretion scale grade of 2 or higher were 13.6 times more likely to aspirate than patients with a lower Murray secretion scale grade. All subgroups showed similar trend. Determination of a Murray secretion scale grade, determined by flexible nasopharyngoscopy, may predict patients at high risk for aspiration. In clinical scenarios where more complete assessments of aspiration risk are immediately impossible or impractical, the Murray secretion scale grade may add valuable information to assist in clinical decision-making in patients with dysphagia.

The chin-down posture is generally recommended in patients with neurogenic dysphagia to prevent tracheal aspiration; however, its effectiveness has not been demonstrated. To videofluoroscopically (VDF) assess the effectiveness of chin-down posture to prevent aspiration in patients with neurogenic dysphagia secondary to acquired brain injury. Randomized, alternating, cross-over study (with and without the chin-down posture) in 47 patients with a VDF diagnosis of aspiration [31 stroke, 16 traumatic brain injury (TBI)] and 25 controls without aspiration (14 stroke, 11 TBI). During the chin-down posture, 55% of patients avoided aspiration (40% preswallow aspiration and 60% aspiration during swallow). The percentage was similar in both etiologies (58% stroke and 50% TBI). Fifty-one percent of patients had silent aspiration; of these, 48% persisted with aspiration while in the chin-down posture. A statistically significant relationship was found between the existence of pharyngeal residue, cricopharyngeal dysfunction, pharyngeal delay time and bolus volume with the persistence of aspiration. The chin-down posture did not change swallow biomechanics in patients without aspiration. Only half the patients with acquired brain injury avoided aspiration during cervical flexion; 48% of silent aspirators continued to aspire during the maneuver. Several videofluoroscopic parameters were related to inefficiency of the maneuver. Therefore, the indication for chin-down posture should be evaluated by videofluoroscopic examination. © 2012 Blackwell Publishing Ltd.

Posterior reversible encephalopathy syndrome (PRES) is associated with several symptoms; of those, visual acuity loss, light oversensitivity (photophobia), and light flashes (photopsia) are known as PRES-related eye symptoms. We report a post-partum woman with PRES associated with hemolysis, elevated liver enzymes, and low platelets syndrome (HELLP), in whom color vision abnormality (achromatopsia) was the sole manifestation. Cesarean section was performed at 28 weeks due to headache, epigastralgia, and severe hypertension. HELLP became evident after delivery. On post-partum day 1, she complained of achromatopsia, stating: "all things look brownish-gray". Ophthalmologic examination was normal, but brain magnetic resonance imaging showed occipital lobe lesions, indicative of PRES, and, interestingly, also color vision center (area V4) lesions, suggesting that the achromatopsia had been caused by brain damage. It may be prudent to question HELLP patients concerning achromatopsia. © 2017 Japan Society of Obstetrics and Gynecology.

The main diagnostic tool for toxic adenomas (TA) is radionuclide imaging indicated in patients with evidence of thyroid nodules in combination with thyrotoxic syndrome. Thyroid ultrasound and fine-needle aspiration biopsy (FNAB) are widely used for the valuation of thyroid masses. There is no literature data concerning the utility of FNAB and related tests for the diagnosis of hyperfunctioning thyroid nodules. The purpose of this study is to determine the levels of free thyroxine (FT4) in the needle washout after FNAB of hot thyroid nodules. The results of our study show that the FT4 levels in needle washout from TA were significantly higher than the surrounding parenchyma and correlated with the hormonal changes in patients with thyroid hyperfunctioning nodules. Further studies on a large number of patients are needed to refine the diagnostic value of this method and evaluate its importance in quantitative risk assessment of thyroid autonomy.

Culture positivity of percutaneous aspiration material" is not included in the current bacteriological criteria for diagnosis of pulmonary nontuberculous mycobacterial (NTM) diseases, which were published by the Infectious Diseases Society of America (IDSA)/American Thoracic Society (ATS) in 2007 or those released by the Japanese Society for Tuberculosis in 2008. However, percutaneous aspiration is a reliable technique for the detection of causative microorganisms isolated from the focus of infection. We discuss the benefits of including positive culture of percutaneous aspiration material in the bacteriological diagnostic criteria of pulmonary NTM diseases. We reviewed the radiological images and clinical courses of pulmonary diseases in which NTM cultures were obtained from percutaneously aspirated materials at our hospital from 1991 to 2011. Aspiration was carried out under local anesthesia, usually with fluoroscopic guidance. After percutaneous insertion of a 22-gauge needle attached to a 20-mL syringe containing about 3 mL of saline, the lesion specimen was withdrawn together with the saline. After the needle was pulled out, the aspirated material and saline were transferred to test tubes for cytological and microbiological examinations. In patients with thin-walled cavitary lesions, saline was injected into the cavity and then aspirated. Percutaneous aspiration was performed in 2,742 patients and NTM disease was detected in 51 patients. Of these 51 patients, 12 had solitary nodular lesions, and in many of these patients, no NTM bacilli could be detected in the sputa or bronchial washing specimens. Mycobacterium avium was identified in 10 of the 12 cases. Four of these 10 patients were followed up after their diagnosis without any treatment: 3 showed spontaneous reduction in lesion size, while 1 patient's condition remained unchanged. Four of the remaining 6 cases were treated with anti-NTM medications, and lesion size reduced in 2 cases, while no change or

To describe the correlation between the functional dysphagia scale and aspiration pneumonia and which characteristics influence the occurrence of aspiration pneumonia in patients with idiopathic Parkinson disease. Fifty-three patients with idiopathic Parkinson disease were prospectively evaluated in this study. Disease severity and functional status were measured by modified Hoehn and Yahr (H&Y) staging, Schwab and England activities of daily living (S-E ADL) scale and Korean version of Mini-Mental State Examination (K-MMSE). Swallowing function was evaluated by the functional dysphagia scale (FDS) and the penetration-aspiration scale (PAS) based on a videofluoroscopic swallowing study. The patients were followed up for 3 months and divided into two groups according to the occurrence of aspiration pneumonia. The correlation between the variables and aspiration pneumonia was analyzed. Eight patients of the 53 patients were allocated to the aspiration pneumonia group and 45 patients to the non-aspiration pneumonia group. The patients in the aspiration pneumonia group had significantly higher H&Y staging, and scored lower on S-E ADL scale and K-MMSE. The patients in the aspiration pneumonia group had significantly higher scores on FDS and PAS. A multiple logistic regression analysis showed that the S-E ADL scale and the FDS were associated with the occurrence of aspiration pneumonia in the patients with Parkinson disease. Given that the FDS can quantitatively assess the functional problems associated with dysphagia, it can be clinically effective in predicting the occurrence of aspiration pneumonia, and the FDS and the S-E ADL scale could be predictive variables for aspiration pneumonia in patients with Parkinson disease.

This paper presents a novel micropipette aspiration (MA) method based on a common pneumatic micro-injection system. This method is the first to quantify the influence of capillary effect on aspiration pressure using a balance pressure model, and in return, uses the capillary effect to quantify the aspiration pressure. Subsequently, the seal between the cell and the micropipette is detected to judge and exclude the ineffective MA attempts. The rationality of the balance pressure model is validated by the designed micropipette-filling experiments. Through applied to elasticity-determination of the cells with different sizes, the feasibility and versatility of this MA method are proved. With abilities to quantify aspiration pressures and detect the seam between the cell and the micropipette, our method is expected to advance the application of the commercial pneumatic injector in the MA of cells. Moreover, with the quantified volume of the liquid entering into the micropipette during MA process, our method also has a potential applicability to the study of the permeability of the cell membrane in the future.

The aim of this study was to report a case of Down syndrome (DS) complicated with bilateral retinal detachment (RD) due to unusual retinal degeneration. A 9-year-old girl complained of bilateral visual disturbance during a follow-up examination for myopia and strabismus. Slit-lamp examination revealed moderate posterior subcapsular cataract in both eyes. B-mode echography showed bilateral bullous RD; however, it was difficult to detect the causal retinal breaks due to poor mydriasis. For treatment, the patient underwent bilateral lensectomy, vitrectomy, and silicone oil tamponade. Intraoperative findings revealed symmetrical retinal breaks and unusual caterpillar-like retinal degeneration on the upper temporal side of both eyes. Three months later, the patient underwent bilateral silicone oil removal and intraocular lens implantation. In this case, the retinal degeneration was morphologically different from retinal lattice degeneration, thus suggesting that it might be involved in the onset of DS-related bilateral RD.

To determine whether the lack of private health insurance places children at increased risk for foreign body ingestion or aspiration. Retrospective review. St. Louis Children's Hospital, a tertiary care center. Consecutive sample of 125 patients with esophageal or airway foreign bodies. Fifty percent of all patients had private health insurance. Fifty-six percent of all preschool patients and 20% of all school-age patients were uninsured (P < 0.01, Fisher's exact test). Eighty-five percent of patients with airway foreign bodies, and 84% of patients with esophageal foreign bodies were in the preschool group. Sixty-one percent of preschool patients and 21% of school-age patients with esophageal foreign bodies were uninsured (P < 0.05). Forty-six percent of preschool patients with food aspiration lacked health insurance (88% of these children were fed the aspirated item). No school-age group was available for comparison. Fifty percent of preschool children with aspiration of non food items were uninsured, as were 16% of their school-age counterparts. Insurance status must be considered as a risk factor for foreign body aspiration and ingestion. Preschool children are more likely to lack private health insurance than school-age children with the same diagnosis. In a majority of aspiration events, the child was being fed the inappropriate food item, perhaps indicating a lack of caretaker education and anticipatory guidance. A direct focus on 'passive protection', anticipatory guidance in clinics for all patients, and public education with emphasis on preventive care are proposed as means to decrease the incidence of airway and esophageal foreign bodies in children.

Cervical auscultation could improve the performance of bedside swallowing test to predict aspiration, especially silent aspiration. The aim of this study is to compare the predictive values of bedside swallowing test performed with and without cervical auscultation by logopedist students who had intensive training on cervical auscultation. 64 patients were included in the study. They all underwent swallowing test alone, combined swallowing test and cervical auscultation, and videofluoroscopic swallowing study as defined gold standard. Two logopedist students, at the end of their training, performed the auscultation and noted their results. 128 tests were performed, 96% of the tests were judged positive for aspiration. When comparing the results of the two different clinical tests, the detection of clinical signs is not improved by the addition of auscultation. Using a penetration aspiration scale threshold >5, the area under the curve measured for the swallowing test alone was significantly higher than that measured for the combined tests (p = 0.03) (0.66 for the swallowing test alone (95% CI between 0.49 and 0.83), and 0.50 for the combined tests (95% CI between 0.31 and 0.69). This study showed no advantage in performing cervical auscultation with bedside swallowing test. Cervical auscultation seems to hamper the assessment, mainly the perception of wet voice and laryngeal motion. These results are compatible with literature but need further confirmation using studies performed with trained logopedists.

This study aims to investigate the correlation between α-amylase in tracheal aspirates and risk factors of aspiration, as well as ventilator-associated pneumonia (VAP), in elderly patients undergoing mechanical ventilation and explore the clinical value of α-amylase for predicting VAP. Tracheal aspirates were collected from elderly patients within 2 weeks after tracheal intubation in mechanical ventilation, and α-amylase was detected. Patients were grouped according to the presence of VAP. The correlation between α-amylase and risk factors of aspiration before intubation, as well as VAP, were analyzed. The sample of this study comprised 147 patients. The average age of these patients was 86.9 years. The incidence of VAP was 21% during the study period. Tracheal aspirate α-amylase level increased with the increase in the number of risk factors for aspiration before intubation, α-amylase level was significantly higher in the VAP group than in the non-VAP group, the area under the receiver operating characteristic curve (ROC) of the diagnostic value of α-amylase for VAP was 0.813 (95% CI: 0.721-0.896), threshold value was 4,681.5 U/L, sensitivity was 0.801 and specificity was 0.793. Logistic multivariate analysis revealed the following risk factors for VAP: a number of risk factors before intubation of ≥3, a Glasgow score of <8 points, the absence of continuous aspiration of subglottic secretion and a tracheal aspirate α-amylase level of >4681.5 U/L. Tracheal aspirate α-amylase can serve as a biomarker for predicting VAP in elderly patients undergoing mechanical ventilation. © 2017 John Wiley & Sons Ltd.

Abnormal Uterine Bleeding- evaluation by Endometrial Aspiration.

PubMed

Singh, Pratibha

2018-01-01

Endometrial evaluation is generally indicated in cases presenting with abnormal uterine bleeding (AUB), especially in women more than 35 years of age. AUB encompasses a variety of presentation, for example, heavy menstrual bleeding, frequent bleeding, irregular vaginal bleeding, postcoital and postmenopausal bleeding to name a few. Many methods are used for the evaluation of such cases, with most common being sonography and endometrial biopsy with very few cases requiring more invasive approach like hysteroscopy. Endometrial aspiration is a simple and safe office procedure used for this purpose. We retrospectively analyzed cases of AUB where endometrial aspiration with Pipette (Medgyn) was done in outpatient department between January 2015 and April 2016. Case records (both paper and electronic) were used to retrieve data. One hundred and fifteen cases were included in the study after applying inclusion and exclusion criteria. Most cases were between 46 and 50 years of age followed by 41-45 years. No cases were below 25 or more than 65 years of age. Heavy menstrual bleeding was the most common presentation of AUB. Adequate samples were obtained in 86% of cases while 13.9% of cases' sample was inadequate for opinion, many of which were later underwent hysteroscopy and/or dilatation and curettage (D and C) in operation theater; atrophic endometrium was the most common cause for inadequate sample. Uterine malignancy was diagnosed in three cases. Endometrial aspiration has been compared with traditional D and C as well as postoperative histopathology in various studies with good results. Many such studies are done in India as well as in western countries confirming good correlation with histopathology and adequate tissue sample for the pathologist to give a confident diagnosis. No complication or side effect was noted with the use of this device. Endometrial aspiration is a simple, safe, and effective method to sample endometrium in cases of AUB avoiding risk of

Aspiration cytologic findings of mammary analogue secretory carcinoma (MASC), a newly established salivary gland neoplasm defined by a t(12;15)(p13;q25) ETV6-NTRK3 translocation, are not fully characterized to date. We report cytologic descriptions of nine cases of molecularly confirmed MASC, including two with unusual findings. Aspiration smears from nine MASCs of the salivary glands were retrospectively reviewed and analyzed according to the cellular and structural features of the corresponding surgical specimens. Aspiration smears of MASC generally reflected the histologic diversity of the tumors. Among usual histologic findings, a micropapillary pattern was associated with a predominance of vacuolated individual cells on aspiration smears, a papillary-cystic pattern with a predominance of thin branching papillary structures, and a microcystic pattern with a predominance of irregular sheets of eosinophilic cells. There were two unusual cases, one with three-dimensional groups of high-grade atypical cells, and one with epithelial clusters floating in a notably mucinous background. These cases represented MASC with high-grade transformation and MASC with cystadenocarcinoma-like features, respectively. The secretory activity of MASC was not prominent in the aspiration specimens. Although unusual cases were present, most MASC cases showed characteristic cytologic findings, which could aid the cytologic diagnosis of MASC. And knowledge of the histologic spectrum of MASC, including high-grade transformation, could be valuable for cytological differential diagnoses of salivary gland tumors, and the management of patients with MASC. © 2014 Wiley Periodicals, Inc.

Aspiration past the tracheal tube cuff has been recognized to be a risk factor for the development of ventilator-associated pneumonia (VAP). This study investigated the effect of closed tracheal suctioning on aspiration of fluid past the tracheal tube cuff in an in vitro benchtop model. High-volume low pressure tube cuffs of 7.5 mm internal diameter (ID) were placed in a 22 mm ID artificial trachea connected to a test lung. Positive pressure ventilation (PPV) with 15 cm H₂O peak inspiratory pressure and 5 cm H₂O positive end-expiratory pressure (PEEP) was used. A closed tracheal suction system (CTSS) catheter (size 14Fr) was attached to the tracheal tube and suction was performed for 5, 10, 15, or 20 seconds under 200 or 300 cm H₂O suction pressures. Amount of fluid (mL) aspirated along the tube cuff and the airway pressure changes were recorded for each suction procedure. Fluid aspiration during different suction conditions was compared using Kruskal-Wallis and Mann-Whitney test (Bonferroni correction [α = .01]). During 10, 15, and 20 seconds suction, airway pressure consistently dropped down to -8 to -13 cm H₂O (P < .001) from the preset level. Fluid aspiration was never observed under PPV + PEEP but occurred always during suctioning. Aspiration along the tube cuff was higher with -300 cm H₂O than with -200 cm H₂O suction pressure (P < .001) and was much more during 15 and 20 seconds suction time as compared to 5 seconds (P < .001). Massive aspiration of fluid occurs along the tracheal tube cuff during suction with the closed tracheal suction system. © SAGE Publications 2011.

2015-02-01

Profound oropharyngeal dysphagia (OPD) is common and costly. Treatment options are limited. The purpose of this investigation was to evaluate the utility of hypopharyngeal suction at the upper esophageal sphincter (UES) to eliminate aspiration. Five different catheters were passed retrograde up the esophagus and positioned at the UES in a cadaver model of profound OPD. Suction was affixed to each catheter. 10 cc of barium was administered into the pyriform sinus, and videofluoroscopy was utilized to evaluate the presence of aspiration. 6 trials were administered per catheter and for a no catheter control. The outcome measures were the incidence of aspiration, the NIH Swallow Safety Scale (NIH-SSS), and UES opening. Control trials with no suction resulted in an aspiration rate of 100 % (6/6 trials). Negative pressure through 16, 18, 24, and 30 Fr catheter resulted in an aspiration rate of 0 % (0/24 trials; p < 0.001), and suction through a 12-Fr catheter resulted in an aspiration rate of 33 % (2/6 trials; p > 0.05). The mean NIH-SSS improved from 7.0 (±0.0) in the control to 0 (±0.0) with hypopharyngeal suction (18 Fr nasogastric catheter; p < 0.001). Mean UES opening improved from 0.0 (±0.0) mm in the control condition to 8.6 (±0.2) mm with a hypopharyngeal catheter (16 Fr Foley catheter; p < 0.001). Negative pressure applied through retro-esophageal suction catheters (>12 Fr) at the level of the UES reduced aspiration by 100 % and significantly increased UES opening in a cadaveric model of profound oropharyngeal dysphagia.

To analyse the cytomorphologic spectrum of Wilms tumour (WT) on aspirates, the largest series reported to date. Adequate aspirates from paediatric renal tumours over a period of 17 years were reviewed and selected if subsequent excision showed WT or aspirates were diagnostic for WT and clinical/radiological evidence consistent with that diagnosis. Smears were re-examined for the proportion of components, degree of pleomorphism and mitosis. Of 110 aspirates, smears were triphasic in 44 (40.0%), biphasic (blastema and tubules) in 36 (32.7%) and monophasic (blastema alone) in 30 (27.3%). Stromal predominance was seen in 11 aspirates (10.0%) and five showed rhabdomyoblastic differentiation; all 11 were triphasic. Mean mitotic rate was 9.3/5000 cells (range 4-39/5000). Nuclear atypia not amounting to anaplasia and without atypical mitoses was seen in 15 (13.6%); these presented diagnostic problems. Two aspirates (1.8%) were considered anaplastic (unfavourable), both having atypical mitoses. Criteria similar to histology (i.e. 3-fold or more variation in nuclear size, marked hyperchromasia with bizarre nuclei and atypical mitoses in a biphasic or triphasic aspirate) helped in distinguishing anaplastic WT. Histopathological correlation in 67 cases showed good correlation of blastemal predominance, stromal predominance and anaplastic histology with the corresponding cytology. However, 9/27 (33.3%) triphasic tumours had only blastemal cells on corresponding aspiration because of sampling error. Cytokeratin was positive in 4 of 20 aspirates with blastema alone. Aspirates from WT were triphasic or biphasic in the majority (72.7%), permitting cytological diagnosis, which was improved by cytokeratin immunocytochemistry. Blastemal and stromal predominance on histology correlated well with cytology, but many triphasic tumours showed only blastema on aspiration. Anaplastic WT can be detected on aspirates using criteria similar to histology. © 2010 Blackwell Publishing Ltd.

Foreign body aspiration remains a common and potentially serious pediatric problem. Most aspirated foreign bodies are food. The education of parents and caregivers about choking hazards and how to avoid them is critical to reduce the incidence of these events. The pediatricians play a key role in promoting injury prevention. We indicate the main characteristics of hazardous food and we present recommendations on age-appropriate meals, adequate forms of food preparation and behavioral rules at mealtimes in order to reduce food choking.

Diagnostic test accuracy studies for ultrasonography-guided fine-needle aspiration and ultrasonography-guided core needle biopsy have shown inconclusive results due to their heterogenous study designs. Our aim was to compare the diagnostic accuracy of ultrasonography-guided fine-needle aspiration versus ultrasonography-guided core needle biopsy for detecting malignant tumors of the salivary gland and for the tissue-specific diagnosis of salivary gland tumors in a single tertiary hospital. This retrospective study was approved by our institutional review board and informed consent was waived. Four hundred twelve patients who underwent ultrasonography-guided fine-needle aspiration (n = 155) or ultrasonography-guided core needle biopsy (n = 257) with subsequent surgical confirmation or clinical follow-up were enrolled. We compared the diagnostic accuracy of ultrasonography-guided fine-needle aspiration and ultrasonography-guided core needle biopsy regarding malignant salivary gland tumors and the correct tissue-specific diagnosis of benign and malignant tumors. We also tested the difference between these procedures according to the operator's experience and lesion characteristics. The inconclusive rates of ultrasonography-guided fine-needle aspiration and ultrasonography-guided core needle biopsy were 19% and 4%, respectively (P < .001). The overall accuracy of ultrasonography-guided core needle biopsy for diagnosing malignant tumors was significantly higher than that of ultrasonography-guided fine-needle aspiration (P = .024). The correct tissue-specific diagnosis rates of ultrasonography-guided fine-needle aspiration and ultrasonography-guided core needle biopsy were 95% versus 97% for benign tumors (P = .648) and 67% versus 80% for malignant tumors (P = .310). Trainees showed significantly lower accuracy with ultrasonography-guided fine-needle aspiration than with ultrasonography-guided core needle biopsy for diagnosing malignant tumors (P = .021).

2017-01-01

The aim of the present study was an evaluation of movement during double aspiration by different manual syringes and one computer-controlled local anesthesia delivery system (C-CLAD). With five different devices (two disposable syringes (2, 5 ml), two aspirating syringes (active, passive), one C-CLAD), simulation of double aspiration in a phantom model was conducted. Two experienced and two inexperienced test persons carried out double aspiration with the injection systems at the right and left phantom mandibles in three different inclination angles (n = 24 × 5 × 2 for each system). 3D divergences of the needle between aspiration procedures (mm) were measured with two video cameras. An average movement for the 2-ml disposal syringe of 2.85 mm (SD 1.63), for the 5 ml syringe of 2.36 mm (SD 0.86), for the active-aspirating syringe of 2.45 mm (SD 0.9), for the passive-aspirating syringe of 2.01 mm (SD 0.7), and for the C-CLAD, an average movement of 0.91 mm (SD 0.63) was seen. The movement was significantly less for the C-CLAD compared to the other systems (p < 0.001). The movement of the needle in the soft tissue was significantly less for the C-CLAD compared to the other systems (p < 0.001). A difference in involuntary movement of the syringe could be seen in comparison between manual and C-CLAD systems. Launching the aspiration by a foot pedal in computer-assisted anesthesia leads to a minor movement. To solve the problem of movement during aspiration with possibly increased false-negative results, a C-CLAD seems to be favorable.

Tracheal aspirate Gram stain has limited sensitivity and specificity for detecting Staphylococcus aureus.

PubMed

2011-01-01

The increasing incidence of respiratory infections due to methicillin resistant Staphylococcus aureus has resulted in increased empirical use of antibiotics active against this pathogen. There are limited data available as to whether the Gram stain of respiratory tract secretions accurately predicts growth of S. aureus. We theorized that the distinctive morphology of S. aureus would allow rapid, accurate identification of the organism in respiratory secretions. The authors reviewed all available Gram stains of tracheal aspirates sent to our hospital's microbiology laboratory between 1 April 2008 and 31 October 2008, while blinded to the culture result, and recorded the presence or absence of organisms with a morphology consistent with S. aureus. These results were correlated with the semiquantitative culture result. Among 136 tracheal aspirates studied, 50 (37%) grew S. aureus. The Gram stain was read as positive for organisms consistent with S. aureus in 34 of these. Among 86 samples that did not grow S. aureus, the Gram stain was read as negative in 62. Therefore, the Gram stain had a sensitivity of 68%, a specificity of 72%, a negative predictive value of 80% and a positive predictive value of 59% for culture of S. aureus. False negative Gram stains were more likely when the culture revealed only rare or small growth of S. aureus (P = 0.01). In this study, the tracheal aspirate Gram stain read by an experienced clinician who was not a microbiologist, was not accurate enough to reliably predict the growth of S. aureus. © 2010 The Authors.

To examine the longitudinal change of pathological findings of the lung and other organs in milk aspiration, an experimental study using a murine model was carried out. Either 0.5 or 1.0 ml cow's milk was instilled into the trachea of rats. From immediately after to 14 days after instillation, the animals were sacrificed, and the lungs, liver, kidneys, and spleen were removed. The results of immunostaining with anti-human α lactalbumin antibody indicated that not only the lung but also the kidney and spleen showed a positive reaction against the antibody over time. Experimentally aspirated milk was detectable in alveoli until 2 days after instillation. It was also detectable in renal tubules from 1 to 6h after instillation. Macrophages containing granules of aspirated milk were observed in splenic red pulp from 3h to 14 days after instillation. Detection of aspirated milk in other organs except the lung would be clear evidence of intravital milk aspiration and would suggest previous or recurrent milk aspiration.

Deferasirox has nephrotoxic effects in the context of chronic therapy. This case report illustrates proximal tubular dysfunction (Fanconi syndrome) due to an acute deferasirox overdose. In response, we trialled plasmapheresis to eliminate the drug. Deferasirox levels were obtained in the context of three rounds of plasmapheresis. Given the half-life model of decay, we concluded that plasmapheresis may not have been successful. The patient ultimately recovered normal tubular function after 2 months. This report is the first to describe acute deferasirox-induced nephrotoxicity, and the application of plasmapheresis that, ultimately, did not change the typical time to recovery. © 2017 John Wiley & Sons Ltd.

The effect of anxiety and depression on patients with acute coronary syndromes (ACS) warrants investigation, especially during periods of economic crisis. To investigate the relation between anxiety and depression in patients presenting with ACS due to financial crisis and to investigate whether these two entities could predict long-term cardiovascular mortality. Anxiety and depression symptoms were assessed in 350 patients (210 men) presenting with ACS, with 70 (20%) patients showing elevated scores (Hellenic Heart Failure Protocol). Over a mean follow-up of 48 months there were 36 (10%) cardiovascular deaths. Cox proportional hazards models adjusted for other prognostic factors (including age, sex, marital status, creatinine levels, left ventricular ejection fraction, heart failure, atrial fibrillation, previous hospitalisation, and baseline medications) showed that elevated anxiety and depression scores significantly predicted cardiovascular mortality (primary outcome) and all-cause mortality. Elevated anxiety and depression symptoms are related to cardiovascular mortality due probably to financial crisis, even after adjustment for other prognostic indicators in patients with ACS, who received optimised medical treatment.

Third Prader-Willi syndrome phenotype due to maternal uniparental disomy 15 with mosaic trisomy 15.

We report on a boy with mosaicism for trisomy 15 and Prader-Willi syndrome (PWS) due to maternal isodisomy for chromosome 15. His phenotype is consistent with PWS and trisomy 15 mosaicism. Although our patient is unusual in having maternal isodisomy rather than the more common maternal heterodisomy, we think that his more severe PWS phenotype is due to his trisomy 15 mosaicism rather than to homozygosity for deleterious chromosome 15 genes. We propose that individuals with PWS have one of three similar but distinctive phenotypes depending on the cause of their condition. Patients with paternal deletions have the typical PWS phenotype, patients with maternal UPD have a slightly milder phenotype with better cognitive function, and those with maternal UPD and mosaic trisomy 15 have the most severe phenotype with a high incidence of congenital heart disease. These phenotype-genotype differences are useful to guide the work-up of patients with suspected PWS and to provide prognostic counseling for families.

Foreign body aspiration in adult airways: therapeutic approach

Hewlett, Justin C.; Rickman, Otis B.; Lentz, Robert J.; Prakash, Udaya B.

2017-01-01

Tracheobronchial foreign body (FB) aspiration is an uncommon but potentially life-threatening event in adults. Symptoms typically consist of a choking event followed by cough and dyspnea, however, these findings are inconsistent and symptoms may mimic more chronic lung diseases such as asthma or chronic obstructive pulmonary disease. Chest radiography and computed tomography can provide information regarding the location and characteristics of foreign bodies and aid in diagnosis. Bronchoscopy remains the gold standard for diagnosis and management of FB aspiration. The authors describe the typical clinical presentation, diagnostic evaluation, and bronchoscopic management of foreign bodies in adult airways with a focus on bronchoscopic techniques and potential complications of FB extraction.

The Nance-Horan syndrome is an X-linked disorder characterized by congenital cataract, facial features, microcornea, microphthalmia, and dental anomalies; most of the cases are due to NHS gene mutations on Xp22.13. Heterozygous carrier females generally present less severe features, and up to 30% of the affected males have intellectual disability. We describe two patients, mother and daughter, manifesting Nance-Horan syndrome. The cytogenetic and molecular analyses demonstrated a 46,X,t(X;1)(p22.13;q22) karyotype in each of them. No copy-number genomic imbalances were detected by high-density microarray analysis. The mother had a preferential inactivation of the normal X chromosome; expression analysis did not detect any mRNA isoform of NHS. This is the first report of Nance-Horan syndrome due to a skewed X chromosome inactivation resulting from a balanced translocation t(X;1) that disrupts the NHS gene expression, with important implications for clinical presentation and genetic counseling.

This article is the first in a series presenting the strongest published evidence for physical and rehabilitation medicine (PRM) to date coming from the Cochrane Collaboration. The intent of the series is to stimulate ideas for reviews and research in neglected areas of PRM. To systematically review the rehabilitation contents of the Cochrane Collaboration on disabilities due to spinal disorders or pain syndromes in adults. The Cochrane Database of Systematic Reviews was searched at the end of June 2013 for articles relevant for PRM about disabilities resulting from spinal disorders or pain syndromes in adults. Retrieved papers were classified according to the PRM approach: active therapies, which require active participation by patients to achieve treatment goals, and passive treatments, which rely on the application of external forces. The quality of the reviews was checked against the AMSTAR checklist. Reviews on spinal disorders or pain syndromes were found in the Cochrane Back Group (CBG) and in the Pain, Palliative and Supportive Care Group (CPPSCG). Thirty-eight (42.8%) of 89 Cochrane reviews in the CBG and 7 (2.4%) of 293 Cochrane reviews in the CPPSCG were included. All were of high quality (range, 8-11 points out of 11 on the AMSTAR checklist). The contents of the reviews are given in detail. This review presents an overview of the current evidence for PRM in the treatment of disabilities due to spinal disorders or pain syndromes in adults. Within PRM there is ample space for research in the Cochrane Collaboration and for producing original studies (randomized controlled trials [RCTs]). To apply evidence-based clinical practice, clinicians must be familiar with the current best evidence.

BACKGROUND Although assessment for aspiration of small volumes of gastric contents in tube-fed patients receiving mechanical ventilation is important, available methods for this purpose are not wholly satisfactory. A potential method is immunoassay of tracheal secretions for the gastric enzyme pepsin. OBJECTIVES To determine the frequency with which pepsin in suctioned tracheal secretions from acutely ill, tube-fed patients receiving mechanical ventilation could be detected via an immunoassay. METHODS A convenience sample of 136 specimens of suctioned tracheal secretions was collected from 30 acutely ill, tube-fed adults receiving mechanical ventilation. Multiple samples were obtained from 26 of the 30 patients (range, 2−11 per subject). An immunoassay with rooster polyclonal antibodies to purified human pepsin was used to detect pepsin in the secretions. RESULTS Fourteen specimens tested positive for pepsin. Secretions from 5 patients accounted for the 14 pepsin-positive results. A significant relationship was found between the position of the head of the bed and the presence of pepsin in tracheal secretions (P< .001). Of the 14 pepsin-positive specimens, 13 (92.9%) were obtained from subjects in a flat position. CONCLUSIONS A pepsin immunoassay can be used to detect pepsin in human tracheal secretions. If pepsin in tracheal secretions is considered an indicator of aspiration of gastric contents, aspiration occurred in 5 of the 30 subjects. A flat position is strongly associated with the presence of pepsin in tracheal secretions. PMID:11888127

Dysphagia and bolus aspiration are two of the most frequent and invalidating symptoms of various neurological diseases. Swallowing disorders often lead to tracheobronchial aspiration with consequent pneumonia episodes. Aspiration pneumonia per se constitutes the most frequent cause of death in these patients, with mortality rate ranging from 20% to 62%. Oropharyngoesophageal scintigraphy (OPES) permits functional quantitative assessment of the different stages of swallowing, together with the detection and quantitative measurement of bolus aspiration. In this work, we analyzed the role of OPES in patients with different neurological conditions to evaluate swallowing and to detect and quantify bolus aspiration. We enrolled 43 neurological patients (25 women and 18 men, mean age 67.3±12.4 yr) complaining of dysphagia with suspected inhalation. All patients underwent OPES with (99m)Tc-nanocolloid using a liquid bolus first, followed by a semi-solid bolus. We evaluated the following parameters: Oral, Pharyngeal and Esophageal Transit Time, Oro-Pharyngeal Retention Index, Esophageal Emptying Rate, and Aspiration Rate (% AR). OPES detected some airway aspiration in 26/43 patients. 19 patients had tracheal aspiration (with a mean 18.1% AR) and the remaining 7 patients had bilateral broncho-pulmonary aspiration (mean 44.9% AR). OPES is a feasible, repeatable and noninvasive method that allows quantitative assessment of bolus aspiration into the tracheobronchial tract, thus representing a useful and accurate tool to guide the most appropriate treatment and to monitor response to therapy in neurological patients with dysphagia.

Cornelia de Lange syndrome is a genetic disease characterized by distinctive facial features, failure to thrive, microcephaly and several malformations associated. Its main endocrinological features are anomalies of the genitalia. We present a 13-year-old boy, who suffered from complicated aspiration pneumonia and showed Cornelia de Lange syndrome phenotype, with global developmental delay, suction-swallowing abnormalities, short stature and abnormal genitalia associated. His bone age was delayed, so he underwent full endocrinological panel. Central hypothyroidism, growth hormone deficiency and low luteinizing hormone-follicle-stimulating hormone levels were observed and multiple pituitary hormone deficiencies diagnosis was made. Basal cortisol, adrenocorticotropic hormone and prolactin levels were normal. He received thyroid hormonal substitution. Multiple pituitary hormone deficiencies are an unusual feature of De Lange syndrome. We suggest evaluating all different endocrine axes in these patients. Sociedad Argentina de Pediatría.

Invasive pneumococcal disease is an uncommon and notifiable disease in Singapore. It is often associated with significant morbidity and mortality. We report a rare case of invasive pneumococcal bacteraemia due to parotitis in a patient with systemic sclerosis and secondary Sjögren's syndrome. We also present a retrospective review of Streptococcus pneumoniae bacteraemia cases in Singapore General Hospital from January 2011 to April 2016. A 59-year-old Malay lady with a history of systemic sclerosis with secondary Sjögren's syndrome presented with fever and left parotid gland swelling. Clinical examination revealed poor salivary pooling and left parotid swelling without fluctuance. Ultrasound of the left parotid gland confirmed acute parotitis without evidence of abscess or sialolithiasis. Blood cultures were positive for S. pneumoniae . She was diagnosed to have invasive pneumococcal bacteraemia secondary to acute parotitis, and treated with intravenous benzylpenicillin with clearance of bacteraemia after 3 days. Upon discharge, her antibiotics were changed to intravenous ceftriaxone to facilitate outpatient parenteral antibiotic therapy for another 2 weeks. She responded favourably to antibiotics at follow-up, with no complications from the bacteraemia. A review of the microbiological records of the Singapore General Hospital revealed 116 cases of pneumococcal bacteraemia, most (80.3 %) of which were due to pneumonia. None were due to parotitis. S. pneumoniae parotitis and subsequent bacteraemia is rare. Prompt recognition of the disease and appropriate use of antibiotics are important. This case highlights that close communication between healthcare workers (microbiologist, rheumatologist and infectious disease specialist) is essential in ensuring good clinical outcomes in patients with a potentially fatal disease.

In vivo ovum pick-up (OPU) in sheep may be improved with a proper choice of aspiration elements (needle and tubing) and aspiration vacuum pressure. In the present study, two experiments were carried out. In Expt 1, visible follicles in ovaries of slaughtered ewes (treated separately according to their diameters: small<3 mm, medium 3-5 mm and large>5 mm) were aspirated using different combinations of the three studied factors such as aspiration flow rate (10, 20, 30, 40 and 50 ml water/min), needle gauge (18 and 20 G) and tubing inner diameter (1, 2 or 3 mm internal diameter). In Expt 2, a study with two 18 G needles of different lengths (18 G: 82 mm; 18 GL: 600 mm) was carried out, using ovaries obtained post-mortem, and performing in vivo laparoscopic follicular aspiration on ewes. We considered good quality oocytes as those with both complete compact cumulus and a homogeneous cytoplasm. Recovery rate, proportion of good quality oocytes (good quality oocytes/100 oocytes recovered) and overall efficiency (good quality oocytes/100 follicles aspirated) were noted. In Expt 1, aspiration flow rate affect remarkable proportion of good quality oocytes (69.5%, 50.5%, 44.8%, 36.5% and 28.3% for flows from 10 to 50 ml/min respectively, p<0.05). Needle gauge did not affect aspiration device efficiency. Thin and intermediate tubings were more effective (overall efficiency rates: 34.9%, 32.3% and 28.1% for 1, 2 and 3 mm respectively, p<0.05). Follicle size did not affect recovery rate, but proportion of good quality oocytes was higher for large (77.9%) and medium (64.4%) follicles (p<0.05). Finally, some combinations of the aspiration device showed greater effectiveness. In Expt 2, needle length did not influence recovery rate, but good quality oocytes rate was significantly modified both post-mortem and in vivo (good quality rate for 18 G vs 18 GL needles: 69.5% vs 47.7% and 58.1% vs 25.4%, post-mortem and in vivo respectively, p<0.05). We conclude that low-aspiration flow

Aspiration pneumonia is thought to be associated with a poor outcome in patients with community acquired pneumonia (CAP). However, there has been no systematic review regarding the impact of aspiration pneumonia on the outcomes in patients with CAP. This review was conducted using the MOOSE guidelines: Patients: patients defined CAP. Exposure: aspiration pneumonia defined as pneumonia in patients who have aspiration risk. Comparison: confirmed pneumonia in patients who were not considered to be at high risk for oral aspiration. Outcomes: mortality, hospital readmission or recurrent pneumonia. Three investigators independently identified published cohort studies from PubMed, CENTRAL database, and EMBASE. Nineteen studies were included for this systematic review. Aspiration pneumonia increased in-hospital mortality (relative risk, 3.62; 95% CI, 2.65–4.96; P < 0.001, seven studies) and 30-day mortality (3.57; 2.18–5.86; P < 0.001, five studies). In contrast, aspiration pneumonia was associated with decreased ICU mortality (relative risk, 0.40; 95% CI, 0.26–0.60; P < 0.00001, four studies). Although there are insufficient data to perform a meta-analysis on long-term mortality, recurrent pneumonia, and hospital readmission, the few reported studies suggest that aspiration pneumonia is also associated with these poor outcomes. In conclusion, aspiration pneumonia was associated with both higher in-hospital and 30-day mortality in patients with CAP outside ICU settings. PMID:27924871

Fine needle aspiration cytology.

Fine needle aspiration cytology is an inexpensive, atraumatic technique for the diagnosis of disease sites. This paper describes the technique and illustrates how it may be applied to the management of tumours throughout the body. The limitations of the method, the dangers of false positive reports, and the inevitability of false negative diagnoses are emphasised. In a clinical context the method has much to offer by saving patients from inappropriate operations and investigations and allowing surgeons to plan quickly and more rationally. It is an economically valuable technique and deserves greater recognition. Images PMID:2578481

Thrombus aspiration in acute myocardial infarction: concepts, clinical trials, and current guidelines.

Vandermolen, Sebastian; Marciniak, Maciej; Byrne, Jonathan; De Silva, Kalpa

2016-05-01

The pathogenesis that underlies acute myocardial infarction is complex and multifactorial. One of the most important components, however, is the role of thrombus formation following atherosclerotic plaque rupture, leading to sudden coronary occlusion and subsequent ischemia and infarction. Thrombus aspiration provides the opportunity of intracoronary clot extraction with the aim to improve coronary and myocardial perfusion, by reducing the risk of no-reflow secondary to distal embolization of thrombus. The utility of thrombus aspiration during primary percutaneous coronary intervention has been assessed in an increasing number of observational and randomized studies. This article reviews the contemporary data and provides insights into the validity of thrombus aspiration in the setting of acute myocardial infarction.

Substantial weakness of the quadriceps muscles is typically observed in patients with arthritis. This is partly due to ongoing neural inhibition that prevents the quadriceps from being fully activated. Evidence from animal studies suggests enhanced flexion reflex excitability may contribute to this weakness. This prospective observational study examined the effects of joint aspiration and intra-articular corticosteroid injection on flexion reflex excitability, quadriceps muscle strength and knee pain in individuals with knee synovitis. Sixteen patients with chronic arthritis and clinically active synovitis of the knee participated in this study. Knee pain flexion reflex threshold, and quadriceps peak torque were measured at baseline, immediately after knee joint aspiration alone and 5 ± 2 and 15 ± 2 days after knee joint aspiration and the injection of 40 mg of methylprednisolone acetate. Compared to baseline, knee pain was significantly reduced 5 (p = 0.001) and 15 days (p = 0.009) post intervention. Flexion reflex threshold increased immediately after joint aspiration (p = 0.009) and 5 (p = 0.01) and 15 days (p = 0.002) post intervention. Quadriceps peak torque increased immediately after joint aspiration (p = 0.004) and 5 (p = 0.001) and 15 days (p <0.001) post intervention. The findings from this study suggest that altered sensory output from an inflamed joint may increase flexion reflex excitability in humans, as has previously been shown in animals. Joint aspiration and corticosteroid injection may be a clinically useful intervention to reverse quadriceps muscle weakness in individuals with knee synovitis.

Percutaneous synovial biopsy has recently been reported to have a high diagnostic value in the preoperative identification of periprosthetic infection of the hip. We report our experience with this technique in the evaluation of patients undergoing revision hip arthroplasty, comparing results of preoperative synovial biopsy with joint aspiration in identifying an infected hip arthroplasty by bacteriological analysis. We retrospectively reviewed the results of the 110 most recent revision hip arthroplasties in which preoperative synovial biopsy and joint aspiration were both performed. Revision surgery for these patients occurred during the period from September 2005 to March 2012. Using this study group, results from preoperative cultures were compared with preoperative laboratory studies and the results of intraoperative cultures. Synovial aspiration was done using an 18- or 20-gauge spinal needle. Synovial biopsy was done coaxially following aspiration using a 22-gauge Chiba needle or 21-gauge Sure-Cut needle. Standard microbiological analysis was performed on preoperative synovial fluid aspirate and synovial biopsy. Intraoperative tissue biopsy bacteriological analysis results at surgical revision were accepted as the "gold standard" for the presence or absence of infection. Seventeen of 110 (15 %) of patients had intraoperative culture-positive periprosthetic infection. Of these 17 cases, there were ten cases where either the synovial fluid aspiration and/or the synovial biopsy were true positive (sensitivity of 59 %, specificity of 100 %, positive predictive value of 100 % and accuracy of 94 %). There were seven cases where aspiration and biopsy results were both falsely negative, but no false-positive results. Similar results were found for synovial fluid aspiration alone. The results of synovial biopsy alone resulted in the identification of seven infected joints with no false-positive result (sensitivity of 41 %, specificity of 100 %, positive

Background and Aims Although the clinical phenotype of Lynch syndrome (also known as Hereditary Nonpolyposis Colorectal Cancer) has been well described, little is known about disease in PMS2 mutation carriers. Now that mutation detection methods can discern mutations in PMS2 from mutations in its pseudogenes, more mutation carriers have been identified. Information about the clinical significance of PMS2 mutations is crucial for appropriate counseling. Here, we report the clinical characteristics of a large series of PMS2 mutation carriers. Methods We performed PMS2 mutation analysis using long range PCR and MLPA for 99 probands diagnosed with Lynch syndrome-associated tumors showing isolated loss of PMS2 by immunohistochemistry. Penetrance was calculated using a modified segregation analysis adjusting for ascertainment. Results Germline PMS2 mutations were detected in 62% of probands (n = 55 monoallelic; 6 biallelic). Among families with monoallelic PMS2 mutations, 65.5% met revised Bethesda guidelines. Compared with the general population, in mutation carriers, the incidence of colorectal cancer was 5.2 fold higher and the incidence of endometrial cancer was 7.5 fold higher. In North America, this translates to a cumulative cancer risk to age 70 of 15–20% for colorectal cancer, 15% for endometrial cancer, and 25–32% for any Lynch syndrome-associated cancer. No elevated risk for non-Lynch syndrome-associated cancers was observed. Conclusions PMS2 mutations contribute significantly to Lynch syndrome but the penetrance for monoallelic mutation carriers appears to be lower than that for the other mismatch repair genes. Modified counseling and cancer surveillance guidelines for PMS2 mutation carriers are proposed. PMID:18602922

Transtracheal aspiration in the diagnosis of pulmonary blastomycosis (17 cases: 2000–2005)

PubMed Central

McMillan, Chantal J.; Taylor, Susan M.

2008-01-01

Blastomyces dermatitidis is a common etiologic agent of fungal pneumonia in dogs. Definitive diagnosis is based on cytologic demonstration of the organism in affected tissues. Fluid obtained through transtracheal aspiration has previously been reported to have a low diagnostic yield for B. dermatitidis organisms. This retrospective study identified B. dermatitidis organisms in 76% of samples when transtracheal aspiration was performed in 17 nonsedated dogs with pulmonary blastomycosis. Transtracheal aspiration is a noninvasive and simple procedure that should be considered as an early diagnostic test whenever blastomycosis is a differential diagnosis in dogs with pulmonary disease.

Corticosteroid-induced asthma: a manifestation of limited hyperinfection syndrome due to Strongyloides stercoralis.

PubMed

Sen, P; Gil, C; Estrellas, B; Middleton, J R

1995-09-01

Inadequate therapeutic response to parenteral corticosteroids in patients with acute bronchial asthma is infrequent. We report four patients whose bronchial asthma symptoms worsened after treatment with parenteral corticosteroids. All had larvae of Strongyloides stercoralis in the stool. The new attack or the exacerbation of asthma appeared to be precipitated by systemic corticosteroid administration. The paradoxic therapeutic response of asthma to glucocorticoides was the major pulmonary manifestation of Strongyloides superinfection; there was no evidence of other organ involvement. Individuals with new onset of bronchial asthma or worsening of asthmatic episodes concurrent with the use of systemic corticosteroids should have thorough investigation for possible superinfection due to Strongyloides stercoralis. This is particularly important for patients who have resided in areas where intestinal helminthic infections are endemic. Discontinuance of steroid therapy or reduction in dosage of parenteral steroids appears necessary. Treatment with thiabendazole appears to be effective in patients with limited hyperinfection syndrome.

To assess ultrasonographically (US) guided needle aspiration of breast abscesses as an alternative to surgical incision and drainage. In our prospective study, 30 patients with 31 breast abscesses (one patient had bilateral breast abscess) underwent percutaneous breast abscess drainage under US guidance with local anaesthesia and oral antibiotics between 1 January 2004 and 31 March 2005. These patients consisted of 16 (53.3%) non-lactating and 14 (46.7%) lactating women, with ages ranging from 18 to 68 years (median, 28 years). The racial distribution comprised 26 (86.7%) Malays, three (10%) Chinese and one (3.3%) Indian. All patients had the chief complaint of breast swelling and 25 (83.3%) had breast pain. Clinically, 28 (93.3%) were found to have a palpable mass. Nine (30%) lesions were in the upper outer quadrant of the left breast. US diameters ranged from 1 to 15 cm (median, 4 cm). The pus volumes varied from 1 to 200 mL (median, 14 mL). Fifteen (50%) patients required only a single aspiration, 10 required multiple aspirations and five required incision and drainage. Those patients in whom needle aspiration failed had multiloculated lesions irrespective of abscess volume and size. Needle aspiration with ultrasound guidance is an effective treatment for breast abscess irrespective of abscess volume and size.

Exploring the efficacy of cyclic vs static aspiration in a cerebral thrombectomy model: an initial proof of concept study.

Current technology for endovascular thrombectomy in ischemic stroke utilizes static loading and is successful in approximately 85% of cases. Existing technology uses either static suction (applied via a continuous pump or syringe) or flow arrest with a proximal balloon. In this paper we evaluate the potential of cyclic loading in aspiration thrombectomy. In order to evaluate the efficacy of cyclic aspiration, a model was created using a Penumbra aspiration system, three-way valve and Penumbra 5Max catheter. Synthetic clots were aspirated at different frequencies and using different aspiration mediums. Success or failure of clot removal and time were recorded. All statistical analyses were based on either a one-way or two-way analysis of variance, Holm-Sidak pairwise multiple comparison procedure (α=0.05). Cyclic aspiration outperformed static aspiration in overall clot removal and removal speed (p<0.001). Within cyclic aspiration, Max Hz frequencies (∼6.3 Hz) cleared clots faster than 1 Hz (p<0.001) and 2 Hz (p=0.024). Loading cycle dynamics (specific pressure waveforms) affected speed and overall clearance (p<0.001). Water as the aspiration medium was more effective at clearing clots than air (p=0.019). Cyclic aspiration significantly outperformed static aspiration in speed and overall clearance of synthetic clots in our experimental model. Within cyclic aspiration, efficacy is improved by increasing cycle frequency, utilizing specific pressure cycle waveforms and using water rather than air as the aspiration medium. These findings provide a starting point for altering existing thrombectomy technology or perhaps the development of new technologies with higher recanalization rates.

We have studied whether hyperbaric oxygen (HBO) prevents different pulmonary aspiration materials-induced lung injury in rats. The experiments were designed in 60 Sprague-Dawley rats, ranging in weight from 250 to 300 g, randomly allotted into one of six groups (n = 10): saline control, Biosorb Energy Plus (BIO), hydrochloric acid (HCl), saline + HBO treated, BIO + HBO treated, and HCl + HBO treated. Saline, BIO, HCl were injected into the lungs in a volume of 2 ml/kg. A total of seven HBO sessions were performed at 2,4 atm 100% oxygen for 90 min at 6-h intervals. Seven days later, rats were sacrificed, and both lungs in all groups were examined biochemically and histopathologically. Our findings show that HBO inhibits the inflammatory response reducing significantly (P < 0.05) peribronchial inflammatory cell infiltration, alveolar septal infiltration, alveolar edema, alveolar exudate, alveolar histiocytes, interstitial fibrosis, granuloma, and necrosis formation in different pulmonary aspiration models. Pulmonar aspiration significantly increased the tissue HP content, malondialdehyde (MDA) levels and decreased (P < 0.05) the antioxidant enzyme (SOD, GSH-Px) activities. HBO treatment significantly (P < 0.05) decreased the elevated tissue HP content, and MDA levels and prevented inhibition of SOD, and GSH-Px (P < 0.05) enzymes in the tissues. Furthermore, there is a significant reduction in the activity of inducible nitric oxide synthase, TUNEL and arise in the expression of surfactant protein D in lung tissue of different pulmonary aspiration models with HBO therapy. It was concluded that HBO treatment might be beneficial in lung injury, therefore, shows potential for clinical use.

Acute renal artery embolism (RAE) is a rare condition associated with significant morbidity and mortality. The treatment strategy for RAE includes anticoagulation with or without thrombolysis or surgical or endovascular embolectomy. We describe here a case presentation of acute RAE secondary to atrial fibrillation treated successfully with Penumbra Indigo Aspiration System, a novel device in peripheral endovascular interventions. Our patient had ongoing symptoms and acute renal failure on presentation with contraindication to thrombolysis given hypertensive emergency. A 6F Penumbra Aspiration catheter was used to aspirate large amounts of thrombus from segmental renal arteries with restoration of flow. Patient's symptoms and renal function returned to baseline after intervention. Penumbra system is used routinely in cerebral endovascular intervention, yet here we describe its potential use in peripheral vascular interventions in addition to a literature review of all available evidence for the different treatment modalities of acute RAE.

A 28-year-old woman presented with urinary retention and suprapubic pain 8 hours after oocyte aspiration. Foley catheter, intravenous fluid bolus, bladder irrigation, and computed tomography with postvoid films that showed a blood clot in the bladder. Patient was discharged home with antibiotics and catheter in place. Clinical follow-up. Patient passed voiding trial 4 days later and was artificially inseminated. No further hematuria or voiding problems were reported, and she had a successful pregnancy. Patients who elect to undergo oocyte aspiration should be warned about the possibility of bladder injury because of the close proximity of the ovaries to the bladder, and physicians should have an appropriate treatment plan.

We describe dual protection (simultaneous flow reversal and distal filter) combined with blood aspiration as a novel technique to provide distal embolic protection during carotid artery stenting (CAS). Between July 2011 and August 2014, 190 patients with internal carotid artery (ICA) stenosis underwent 190 CAS procedures as follows. After post-dilation of the stent using dual protection, the aspiration catheter was placed between the distal filter and the proximal end of the stent, and the blood was aspirated several times from the ICA. We assessed hyper-intensity spots in diffusion-weighted images (DWI), and major adverse events (MAE) defined as major stroke, myocardial infarction and death after CAS. We then assessed visible debris captured in aspirated blood, the distal filter and a blood filter during flow reversal. The overall technical success rate was 100 %, and all stenoses were dilated. Hyper-intense spots were found in 33 (17.3 %) of 190 DWI. The rate of MAE within 30 days was 1.05 % (2/190). Visible debris in 175 of 190 CAS procedures was captured in 92 (52.5 %) of these 175. In 25 (27.2 %) of these 92, visible debris was captured in all of aspirated blood, the distal filter and the blood filter during flow reversal, only the blood filter during flow reversal (n = 19; 20.7 %), only the distal filter (n = 14; 15.2 %), only aspirated blood (n = 11; 12 %), aspirated blood and the blood filter during flow reversal (n = 10; 10.8 %), aspirated blood and the distal filter (n = 7; 7.6 %) and the distal filter and blood filter during flow reversal (n = 6; 6.5 %). Adding a distal filter and blood aspiration to flow reversal during CAS could provide effective distal embolic protection.

The goal of this study was to evaluate the efficacy of simple aspiration of air from the pleural space to prevent increased pneumothorax and avoid chest tube placement in cases of pneumothorax following interventional radiological procedures performed under computed tomography fluoroscopic guidance with the transthoracic percutaneous approach. While still on the scanner table, 102 cases underwent percutaneous manual aspiration of a moderate or large pneumothorax that had developed during mediastinal, lung, and transthoracic liver biopsies and ablations of lung and hepatic tumors (independent of symptoms). Air was aspirated from the pleural space by an 18- or 20-gauge intravenous catheter attachedmore » to a three-way stopcock and 20- or 50-mL syringe. We evaluated the management of each such case during and after manual aspiration. In 87 of the 102 patients (85.3%), the pneumothorax had resolved completely on follow-up chest radiographs without chest tube placement, but chest tube placement was required in 15 patients. Requirement of chest tube insertion significantly increased in parallel with the increased volume of aspirated air. When receiver-operating characteristic curves were applied retrospectively, the optimal cutoff level of aspirated air on which to base a decision to abandon manual aspiration alone and resort to chest tube placement was 670 mL. Percutaneous manual aspiration of the pneumothorax performed immediately after the procedure might prevent progressive pneumothorax and eliminate the need for chest tube placement. However, when the amount of aspirated air is large (such as more than 670 mL), chest tube placement should be considered.« less

Hematoxylin Bodies in Pediatric Bone Marrow Aspirates and Their Utility in the Diagnosis of Systemic Lupus Erythematosus.

2017-01-01

In our recent case report, the finding of lupus erythematosus (LE) cells in a bone marrow aspirate led to the diagnosis of systemic lupus erythematosus (SLE) and appropriate treatment, although the patient was not clinically suspected to have SLE. To determine whether LE cells are present in the bone marrow aspirates of SLE patients, but overlooked in routine bone marrow morphology review, bone marrow aspirates from 30 pediatric patients (15 with SLE and 15 with other diagnoses) evaluated by rheumatologists were reviewed. LE cells were found in the bone marrow aspirates of only 1 SLE patient and none in non-SLE patients. However, hematoxylin bodies were identified in 53% (8/15) of SLE patients. Neither hematoxylin bodies nor LE cells were found in the aspirates from patients with other disorders. Three additional pediatric patients identified prospectively were found to have hematoxylin bodies in the bone marrow aspirates. Although the diagnosis was not initially suspected, 2 of the 3 patients were subsequently diagnosed with SLE. All patients with hematoxylin bodies and SLE had antinuclear antibody titers ≥1:640 with a homogeneous staining pattern. In addition, bone marrow aspirates of 9 adult patients were reviewed, and neither LE cells nor hematoxylin bodies were identified. In summary, hematoxylin bodies were present in the bone marrow aspirates of many pediatric SLE patients, while LE cells were rare. The finding of hematoxylin bodies in pediatric bone marrow aspirates is a helpful and specific diagnostic clue that may lead to the diagnosis of SLE when other clinical features are nonspecific.

Bilateral symmetrical adrenal hypermetabolism on FDG PET/CT due to Cushing syndrome in well differentiated neuroendocrine carcinoma.

2016-01-01

The (18)F-FDG PET/CT scan has been suggested for whole-body imaging to identify ectopic adrenocorticotrophic hormone secreting tumours, but there are some challenges involved. The case of a patient is presented, who was admitted with the pre-diagnosis of ectopic ACTH syndrome. On the CT, a nodular lesion was detected in the medial segment of the right lung. The FDG uptake of the lesion seemed to be increased visually, but was not pathological quantitatively (SUVmax: 1.8) on the PET/CT. There was also diffuse increased uptake (SUVmax: 14.2) in the enlarged adrenal glands. The lesion was reported as a possible malignant lesion with low FDG affinity, such as a low grade neuroendocrine tumour, while the diffuse enlarged adrenal glands with high uptake were interpreted as diffusely hyperplasic, due to Cushing's syndrome. The patient was treated with a surgical wedge resection. The histopathological diagnosis confirmed that the tumour was a grade 1 well-differentiated neuroendocrine carcinoma.

To compare outcomes using the novel portable endoscopy with that of nasogastric (NG) aspiration in patients with gastrointestinal bleeding. Patients who underwent NG aspiration for the evaluation of upper gastrointestinal (UGI) bleeding were eligible for the study. After NG aspiration, we performed the portable endoscopy to identify bleeding evidence in the UGI tract. Then, all patients underwent conventional esophagogastroduodenoscopy as the gold-standard test. The sensitivity, specificity, and accuracy of the portable endoscopy for confirming UGI bleeding were compared with those of NG aspiration. In total, 129 patients who had GI bleeding signs or symptoms were included in the study (age 64.46 ± 13.79, 91 males). The UGI tract (esophagus, stomach, and duodenum) was the most common site of bleeding (81, 62.8%) and the cause of bleeding was not identified in 12 patients (9.3%). Specificity for identifying UGI bleeding was higher with the portable endoscopy than NG aspiration (85.4% vs 68.8%, P = 0.008) while accuracy was comparable. The accuracy of the portable endoscopy was significantly higher than that of NG in the subgroup analysis of patients with esophageal bleeding (88.2% vs 75%, P = 0.004). Food material could be detected more readily by the portable endoscopy than NG tube aspiration (20.9% vs 9.3%, P = 0.014). No serious adverse effect was observed during the portable endoscopy. The portable endoscopy was not superior to NG aspiration for confirming UGI bleeding site. However, this novel portable endoscopy device might provide a benefit over NG aspiration in patients with esophageal bleeding.

An understanding of how particles are inhaled into the human nose is important for developing samplers that measure biologically relevant estimates of exposure in the workplace. While previous computational mouth-breathing investigations of particle aspiration have been conducted in slow moving air, nose breathing still required exploration. Computational fluid dynamics was used to estimate nasal aspiration efficiency for an inhaling humanoid form in low velocity wind speeds (0.1–0.4 m s−1). Breathing was simplified as continuous inhalation through the nose. Fluid flow and particle trajectories were simulated over seven discrete orientations relative to the oncoming wind (0, 15, 30, 60, 90, 135, 180°). Sensitivities of the model simplification and methods were assessed, particularly the placement of the recessed nostril surface and the size of the nose. Simulations identified higher aspiration (13% on average) when compared to published experimental wind tunnel data. Significant differences in aspiration were identified between nose geometry, with the smaller nose aspirating an average of 8.6% more than the larger nose. Differences in fluid flow solution methods accounted for 2% average differences, on the order of methodological uncertainty. Similar trends to mouth-breathing simulations were observed including increasing aspiration efficiency with decreasing freestream velocity and decreasing aspiration with increasing rotation away from the oncoming wind. These models indicate nasal aspiration in slow moving air occurs only for particles <100 µm. PMID:24665111

Our purpose was to review needle aspiration of breast abscesses and identify factors associated with treatment by aspiration alone versus aspiration with surgical incision and drainage (I/D). This Institutional Review Board-approved, retrospective review of the breast ultrasound database from 2008 to 2010 identified 40 patients (41 abscesses) who underwent aspiration, with or without I/D. Demographics, imaging, number of aspirations, and microbiology were reviewed. Twenty-two abscesses underwent aspiration only, 16 > 3 cm, 6 ≤ 3 cm (mean 4.3 cm, range 0.9-10 cm). Known risk factors included lactational (11), 3 weeks post partum (1), pregnancy (1), recent biopsy/lumpectomy (5). Nineteen abscesses underwent aspiration and I/D, 15 > 3 cm, 4 ≤ 3 cm (mean 4.1 cm, range 2.2-7.5 cm). Known risk factors included lactational (4), recurrent subareolar abscess (4), diabetes (3), hydradenitis suppuritiva (1), nipple piercing (2), smoking (1), pregnancy (1), HIV (1), and lumpectomy (1). Identified reasons for I/D included lack of improvement/recurrence (12), fistula (3), and one electively after clinical improvement of a recurrent subareolar abscess. Abscesses associated with pregnancy and lactation or breast biopsy are effectively managed with aspiration, even when large. Recurrence, chronicity, or fistula may require surgical intervention. © 2014 Wiley Periodicals, Inc.

Who Aspires to a Science Career? A comparison of survey responses from primary and secondary school students

There is broad international agreement about the importance of increasing participation in science once it is no longer compulsory in school, particularly among groups who have been historically underrepresented in science. Previous research reflects that despite broadly positive attitudes to science in and outside of school, there is limited translation of these attitudes into later aspirations and participation in science. The ASPIRES project, a five-year longitudinal study, has sought to understand students' science and career aspirations between the ages of 10 and 14 and to identify factors that contribute to, or hinder, the development of aspirations in science. Utilising data from two cross-sectional surveys conducted with students in their last year of primary school (9300 students) and in their third year of secondary school (4,600 students), we explore who is most likely to hold science aspirations and what factors seem to be connected to those aspirations at both time points. Descriptive, multivariate and multilevel modelling analyses of the data reflect consistency in who holds science aspirations, as well as highlighting that the factors connected to these aspirations-attitudes to school science and parental attitudes-are similar at both times. However, for many students, positive attitudes to school science and positive parental attitudes to science are not translating into children wanting a career in science. We suggest that differences in 'science capital' may help explain this persistent gap.

A rare case of Jarcho Levin syndrome (JLS) presenting as a lethal progressive respiratory insufficiency in early neonatal period is reported. The neonate had classical features of this syndrome including vertebral segmentation defects, typical costo-vertebral fusion defects and scoliosis resulting in small thoracic volume and limited chest expansion; all consistent with a clinical diagnosis of JLS with thoracic insufficiency. In addition, our case had a rare association of dextrocardia and acyanotic congenital heart disease. PMID:24741543

Obstructive sleep apnoea/hypopnoea syndrome in adults with Down syndrome

PubMed Central

2016-01-01

Key points Adults with Down syndrome are predisposed to obstructive sleep apnoea/hypopnoea syndrome (OSAHS) due to overlap between the Down syndrome phenotype and OSAHS risk factors. The prevalence of OSAHS in adults with Down syndrome is estimated at 35–42%. This is up to ten-times higher than in the general adult population. Symptoms of OSAHS, including behavioural and emotional disturbances as well as standard symptoms such as sleepiness, should be monitored as part of regular health surveillance in adults with Down syndrome. There is evidence that the use of continuous positive airway pressure (CPAP) therapy in adults with Down syndrome and comorbid OSAHS can lead to significant improvements in subjective sleepiness, behaviour and cognitive function, though further large-scale trials are required. Educational aims To discuss the relationship between the phenotypic features of Down syndrome and the risk factors for obstructive sleep apnoea/hypopnoea syndrome (OSAHS). To examine the prevalence of OSAHS in adults with Down syndrome. To review recent research into the effectiveness of treatment of OSAHS in adults with Down syndrome using continuous positive airway pressure (CPAP) therapy. Obstructive sleep apnoea/hypopnoea syndrome (OSAHS) is characterised by repeated cycles of upper airway obstruction during sleep, leading to diurnal symptoms. Individuals with Down syndrome are predisposed to OSAHS due to overlap between the Down syndrome phenotype and OSAHS risk factors. Recent large studies using subjective and objective measures estimate that OSAHS affects around 40% of adults with Down syndrome, in contrast to 2–4% of the general adult population. The “double-hit” of comorbid Down syndrome and OSAHS may accelerate cognitive decline in adults with Down syndrome. However, with the appropriate care and support, OSAHS can be treated effectively in this group using continuous positive airway pressure (CPAP) therapy, improving daytime function and behaviour
