    The compartment syndrome is defined as a condition in which high pressure within a closed fascial space (muscle compartment) reduces capillary blood perfusion below the level necessary for tissue viability'. This condition occurs in acute and chronic (exertional) forms, and may be secondary to a variety of causes. The end-result of an extended period of elevated intramuscular pressure may be the development of irreversible tissue injury and Volkmann's contracture. The goal of treatment of the compartment syndrome is the reduction of intracompartmental pressure thus facilitating reperfusion of ischaemic tissue and this goal may be achieved by decompressive fasciotomy. Controversy exists regarding the critical pressure-time thresholds for surgical decompression and the optimal diagnostic methods of measuring intracompartmental pressures. This paper will update and review some current knowledge regarding the pathophysiology, aetiology, diagnosis, and treatment of the acute compartment syndrome.

    We report the case of a young male patient who underwent intra-medullary nailing for a closed, displaced mid-shaft fracture of tibia and fibula. He was commenced on patient controlled analgesia post-operatively. A diagnosis of compartment syndrome in the patient\\'s leg was delayed because he did not exhibit a pain response. This ultimately resulted in a below-knee amputation of the patient\\'s leg. We caution against the use of patient controlled analgesia in any traumatised limb distal to the hip or the shoulder.

    Full Text Available Acute compartment syndrome is a serious condition requiring immediate medical care. A lack of urgent medical treatment can result in serious complications such as loss of function and even amputation. While the pathophysiology of acute compartment syndrome is well understood, numerous potential causes are still being discovered. A rare cause of acute compartment syndrome is IV infiltration. We present a case of acute compartment syndrome resulting from intravenous infusion due to proximal placement of a patient identification bracelet. We conclude that both routine evaluation for IV infiltration and proximal placement of IV lines are essential for prevention of acute compartment syndrome.

    2016-01-01

    Full Text Available Gluteal compartment syndrome (GCS is extremely rare when compared to compartment syndrome in other anatomical regions, such as the forearm or the lower leg. It usually occurs in drug users following prolonged immobilization due to loss of consciousness. Another possible cause is trauma, which is rare and has only few reports in the literature. Physical examination may show tense and swollen buttocks and severe pain caused by passive range of motion. We present the case of a 70-year-old man who developed GCS after prolonged anterior-posterior pelvis compression. The physical examination revealed swelling, scrotal hematoma, and left ankle extension weakness. An unstable pelvic ring injury was diagnosed and the patient was taken to surgery. Measurement of the intracompartmental pressure was measured in the operating room, thereby confirming the diagnosis. Emergent fasciotomy was performed to decompress the three affected compartments. Trauma surgeons must be aware of the possibility of gluteal compartment syndrome in patients who have an acute pelvic trauma with buttock swelling and excessive pain of the gluteal region. Any delay in diagnosis or treatment can be devastating, causing permanent disability, irreversible loss of gluteal muscles, sciatic nerve palsy, kidney failure, or even death.

    Leg 201 Tl-SPECT in chronic exertional compartment syndrome Background: The chronic exertional compartment syndrome is one of the most frequent origins regarding leg pain due to sport training. The diagnosis can be established by invasive compartment pressure measurement. The aim of this study is to evaluate the role that could have 201 Tl-SPECT for patients with suspicion of compartment syndrome. Patients and methods: 51 leg 201 Tl-SPECT exams were performed (exercise - and rest without reinjection) in 49 patients; 28 had compartment syndrome confirmed by pressure measurement. About 100 MBq of 201 Tl were injected during exercise, when pain appeared or at least after 25 minutes exercise. We studied mean percentages of level uptake for each compartment, referred to the maximal uptake of both legs. Results: 47 compartments were concerned by compartment syndrome and 361 compartments were not. Scintigraphic patterns in compartments are reversible ischaemia (45%), uptake stability (36%) or reverse redistribution (19%); these patterns are not linked to compartment syndrome. However, there is a significant difference of rest 201 Tl level uptake between compartments with and without compartment syndrome and a significant correlation between muscular pressure measurement and rest level uptake. Conclusion: 201 Tl-SPECT shows that only ischaemia does not explain compartment syndrome. Moreover, it allows to predict pressure variation during exercise but it does not offer any interest in order to select patients for muscular invasive pressure measurement. (author)

  16. The pathophysiology of the acute compartment syndrome.

    The acute compartment syndrome is a condition in which increased pressure within a limited space compromises the circulation and function of the tissues therein, resulting in tissue ischaemia, necrosis and nerve damage. This rise in tissue pressure originates in a decrease of the compartment size or increase of the intracompartmental volume by oedema and/or haemorrhage. Following the arterio-venous gradient theory, capillary blood flow may be impaired through increased venous pressure, decreased arterial pressure and increased peripheral vascular resistance. Often, compartment syndromes develop during reperfusion following a period of ischaemia. During ischaemia, there is a gradual depletion of intracellular stores of high energy phosphate bonds and glycogen stores. There is a buildup of products of glycolysis, particularly lactic acid, with accompanying hydrogen ion accumulation as well as an increase in intracellular reducing agents. Reperfusion may, instead of restoring normal muscle metabolic activity, cause harmful effects by washing out necessary precursors for adenine nucleotide resynthesis. Production of oxygen free radicals occurs with ensuing lipid peroxidation, and calcium influx occurs upon reoxygenation with resultant disruption of oxidative rephosphorylation in the mitochondria. Furthermore, several lines of evidence suggest that white blood cells are important in the pathogenesis of reperfusion injury. Upregulation of both neutrophil receptors and endothelial leucocyte adhesion molecules leads to the sequestration of white blood cells in the muscle with prolongation of the reperfusion injury. This subsequently results in damage to remote organs such as lungs, liver, heart and kidneys.

    Full Text Available Objective: to substantiate the choice of a gastrointestinal tract (GIT function support regimen as a mode for correction of the abdominal compartment syndrome (ACS. Subjects and methods. Forty-three patients with different causes of inadequate GIT function of various origin and ACS (disseminated peritonitis (45%, pancreatitis (24%, and severe concomitant injury (31% were examined. Group 1 (control received complete parenteral nutritional feeding (n=23; APACHE II scores, 21±4; calculated probability of fatal outcome, 33.5%. In Group II (study, complete parenteral feeding in the first 24 hours after stabilization was supplemented with GIT function support with Pepsisorb (Nutricia in doses of 500, 1000, and 1500 ml on days 1, 2, and 3, respectively (n=20; APACHE II scores, 20±6; calculated probability of fatal outcome, 37.1%. During early enteral nutritional support, the SOFA score was significantly less than that in Group 1 on days 2—3; the oxygenation index significantly increased on day 3; the value of intra-abdominal hypertension decreased to the control values. The positive effect of the GIT function support regimen on regression of the multiple organ dysfunction syndrome (MODS was confirmed by the lowered levels of biological markers (von Willebrand factor (WF and endothelin-1 as markers of endothelial damage of MODS. Correlation analysis showed a direct correlation between the markers of endothelial damage and the SOFA scores (r=0.34; p=0.05 for WF and r=0.49;p=0.03 for endothelin. Conclusion. The GIT function support regimen via early enteral alimentation with Peptisorb, which was initiated in the first 24 hours after admission, is able to level off the manifestations of the early stages of the abdominal compartment syndrome, with the acceptable values of oxygen balance and water-electrolyte and osmotic homeostasis being achieved.

    Intraabdominal hypertension (IAH) and abdominal compartment syndrome (ACS) are rare conditions with high mortality. IAH is an intraabdominal pressure (IAP) above 12 mmHg and ACS an IAP above 20 mmHg with evidence of organ dysfunction. IAP is measured indirectly via the bladder or stomach. Various...... medical and surgical conditions increase the intraabdominal volume. When the content exceeds the compliance of the abdominal wall, the IAP rises. Increased IAP affects the functioning of the brain, lungs, circulation, kidneys, and bowel. The treatment of ACS is a reduction of IAP Udgivelsesdato: 2008/2/11...

    Orbital compartment syndrome (OCS) is a rare cause of blindness following intracranial surgery. We report a patient with OCS following intracranial cerebrovascular surgery precipitated by severe straining. OCS occurred due to a rapid increase in intraorbital pressure within the rigid confines of the orbit causing hypoperfusion of critical neural structures, which resulted in visual loss and a complete external ophthalmoplegia. Treatment involved urgent surgical soft tissue decompression of the orbit, corticosteroids and osmotic agents. It is important to consider OCS as a cause of blindness in the neurosurgical postoperative setting as without rapid treatment this condition has a very poor prognosis. Crown Copyright © 2012.

  1. Gluteal Compartment Syndrome After Prolonged Immobilisation

    2009-04-01

    Full Text Available Muscles in the gluteal region are confined by distinct fascial attachments which can potentially result in compartment syndrome. A 74-year-old chronic drinker was admitted to the medical ward after being found drunk on the street. He noticed acute painful swelling of the right side of his buttock the following morning and recalled a slip and fall prior to his blackout. The whole right half of the buttock was tense with erythematous overlying skin. Examination revealed sciatic nerve palsy and myoglobinuria. Emergency fasciotomy and debridement were performed. Intra-operative pressure measurement confirmed a grossly elevated intra-compartmental pressure. Gluteal compartment syndrome is an extremely rare condition and has only been scantily documented previously in case reports. Early diagnosis is crucial but delay recognition is common from lack of knowledge of the condition and readily results in permanent sciatic nerve injury and acute renal shutdown from myoglobinuria. Awareness of the condition, early diagnosis and prompt exploration provide the only chance of avoiding these devastating consequences. Acute swelling diffusely affecting the whole or one side of the buttock, a history of trauma and prolonged local pressure impingement associated with pain out of proportion to the clinical signs should raise a suspicion of this rare condition.

    Metacarpal fractures are common injuries, accounting for approximately 30% to 40% of all hand fractures and with a lifetime incidence of 2.5%. Traditionally regarded as an innocuous injury, metacarpal fractures tend to be associated with successful outcomes after closed reduction and immobilization. Hand compartment syndrome (HCS) is a rare clinical entity with potential devastating consequences in terms of loss of function and quality-of-life outcomes. We discuss the case of a 44-year-old woman presenting with multiple closed metacarpal fractures as a result of low-energy trauma, complicated by acute HCS. We review the presentation, clinical assessment, and optimal surgical management of acute HCS with reference to international literature.

    2013-11-01

    Distal biceps brachii tendon rupture is an uncommon injury. Compartment syndrome of the upper arm is rarely described in the literature. The diagnosis of upper arm compartment syndrome requires a high index of suspicion, and emergent surgical treatment with fasciotomy in the acute setting is necessary to avoid devastating neurovascular complications. This article reports a case of acute compartment syndrome of the anterior compartment of the upper arm after a complete rupture of the distal biceps brachii tendon. A healthy 45-year-old man presented with increasing arm pain; paresthesia in the lateral antebrachial cutaneous nerve distribution; and a tense, swollen anterior compartment of his upper arm. Side port catheter absolute pressure measurement was 83 mm Hg with a diastolic blood pressure of 92 mm Hg. The patient underwent an emergent fasciotomy and was found to have a complete rupture of his distal biceps brachii tendon. He subsequently underwent distal biceps tendon repair and delayed primary closure of his incision. Postoperatively, his paresthesia improved and he has no neurological deficit. There is a paucity of case reports describing compartment syndrome after rupture of either the proximal or distal end of the biceps brachii tendon, and none of the reports describe compartment syndrome of the upper arm after rupture of the distal biceps tendon. This article highlights an unusual complication of an uncommon injury and reviews diagnostic and treatment principles for the management of acute compartment syndrome of the upper arm.

    This article reviews recent developments related to intra-abdominal hypertension (IAH)/abdominal compartment syndrome (ACS) and clinical practice guidelines published in 2013. IAH/ACS often develops because of the acute intestinal distress syndrome. Although the incidence of postinjury ACS is decreasing, IAH remains common and associated with significant morbidity and mortality among critically ill/injured patients. Many risk factors for IAH include those findings suggested to be indications for use of damage control surgery in trauma patients. Medical management strategies for IAH/ACS include sedation/analgesia, neuromuscular blocking and prokinetic agents, enteral decompression tubes, interventions that decrease fluid balance, and percutaneous catheter drainage. IAH/ACS may be prevented in patients undergoing laparotomy by leaving the abdomen open where appropriate. If ACS cannot be prevented with medical or surgical management strategies or treated with percutaneous catheter drainage, guidelines recommend urgent decompressive laparotomy. Use of negative pressure peritoneal therapy for temporary closure of the open abdomen may improve the systemic inflammatory response and patient-important outcomes. In the last 15 years, investigators have better clarified the pathogenesis, epidemiology, diagnosis, and appropriate prevention of IAH/ACS. Subsequent study should be aimed at understanding which treatments effectively lower intra-abdominal pressure and whether these treatments ultimately affect patient-important outcomes.

    Full Text Available Objective. To describe a single case of Systemic Capillary Leak Syndrome (SCLS with a rare complication of compartment syndrome. Patient. Our patient is a 57-year-old male, referred to our hospital due to polycythemia (hemoglobin (Hgb of 220 g/L, hypotension, acute renal failure, and bilateral calf pain. Measurements and Main Results. The patient required bilateral forearm, thigh, and calf fasciotomies during his ICU stay and continuous renal replacement therapy was instituted following onset of acute renal failure and oliguria. Ongoing hemodynamic (Norepinephrine and Milrinone infusion and respiratory (ventilator support in the ICU was provided until resolution of intravascular fluid extravasation. Conclusions. SCLS is an extremely rare disorder characterized by unexplained episodic capillary hyperpermeability, which causes shift of volume and protein from the intravascular space to the interstitial space. Patients present with significant hypotension, hemoconcentration, hypovolemia, and oliguria. Severe edema results from leakage of fluid and proteins into tissue. The most important part of treatment is maintaining stable hemodynamics, ruling out other causes of shock and diligent monitoring for complications. Awareness of the clinical syndrome with the rare complication of compartment syndrome may help guide investigations and diagnoses of these critically ill patients.

    Full Text Available Abdominal compartment syndrome (ACS is defined as an elevated intraabdominal pressure with evidence of organ dysfunction. The majority of published reports of ACS are in neonates with abdominal wall defects and in adults following trauma or burns, but it is poorly described in children. We describe the unusual presentation of an 11-year-old boy with a long history of chronic constipation who developed acute ACS requiring resuscitative measures and emergent disimpaction. He presented with a 2-week history of increasing abdominal pain, nausea, diminished appetite and longstanding encopresis. On exam, he was emaciated with a massively distended abdomen with a palpable fecaloma. Abdominal XR confirmed these findings. Within 24 hours of presentation, he became tachycardic and oliguric with orthostatic hypotension. Following two enemas, he acutely deteriorated with severe hypotension, marked tachycardia, acute respiratory distress, and a declining mental status. Endotracheal intubation, fluid boluses, and vasopressors were commenced, followed by emergent surgical fecal disimpaction. This resulted in rapid improvement in vital signs. He has been thoroughly investigated and no other condition apart from functional constipation has been identified. Although ACS secondary to constipation is extremely unusual, this case illustrates the need to actively treat constipation and what can happen if it is not.

    2011-01-01

    Full Text Available A 48 year old male admitted to the intensive care unit after a cardiac arrest complicated by a stroke intra-operatively during automatic implantable cardioverter defibrillator placement. He post-operatively developed a rigid abdomen, elevated peak and plateau pressures, hypoxia and renal insufficiency. He was diagnosed with abdominal compartment syndrome with an intra-abdominal compartment pressure of 40mmHg. The patient was administered 10 mg of intravenous cisatracuriumbesylate in preparation for bedside surgical abdominal decompression. Cisatracurium eliminated the patients need for surgical intervention by reducing his abdominal compartment pressures to normal and improving his hypoxia and renal function. This case illustrates that neuromuscular blockade should be attempted in patients with abdominal compartment syndrome prior to surgical intervention.

  9. Compartment syndrome after intramedullary nailing of the tibia.

    Tischenko, G J; Goodman, S B

    1990-01-01

    Three patients had compartment syndrome of the leg after tibial intramedullary nailing with reaming. They were all treated successfully with emergency fasciotomy. A prospective study was done of seven additional patients who had continual monitoring of the pressure in the deep posterior compartment during tibial intramedullary nailing with reaming. In five of them, the procedure was performed three weeks or less after injury and in the remaining two, the nailing was performed later for the treatment of non-union. Two pressure peaks in the deep posterior compartment were noted: one after strong longitudinal traction was applied and the fracture was reduced and the other during intramedullary reaming. Intraoperative pressure of thirty millimeters of mercury or more were recorded in three of the seven patients. In the treatment of tibial fractures, operative procedures that involve forceful traction for a long time may predispose the patient to compartment syndrome in the leg. Close clinical observation of such patients is needed. When there is a high risk of compartment syndrome, monitoring of the pressure in the compartment may be prudent.

    Inflammatory edema after ischemia-reperfusion may impair renal allograft function after kidney transplantation. This study examines the effect of edema-related pressure elevation on renal function and describes a simple method to relieve pressure within the renal compartment. Subcapsular pressure at 6, 12, 24, 48 hr, and 18 days after a 45 min warm ischemia was determined in a murine model of renal ischemia-reperfusion injury. Renal function was measured by Tc-MAG3 scintigraphy and laser Doppler perfusion. Structural damage was assessed by histologic analysis. As a therapeutic approach, parenchymal pressure was relieved by a standardized circular 0.3 mm incision at the lower pole of the kidney capsule. Compared with baseline (0.9+/-0.3 mm Hg), prolonged ischemia was associated with a sevenfold increase in subcapsular pressure 6 hr after ischemia (7.0+/-1.0 mm Hg; P<0.001). Pressure levels remained significantly elevated for 24 hr. Without therapy, a significant decrease in functional parameters was found with considerably reduced tubular excretion rate (33+/-3.5%, P<0.001) and renal perfusion (64.5+/-6.8%, P<0.005). Histologically, severe tissue damage was found. Surgical pressure relief was able to significantly prevent loss of tubular excretion rate (62.5+/-6.8%, P<0.05) and renal blood flow (96.2+/-4.8%; P<0.05) and preserved the integrity of renal structures. Our data support the hypothesis of the existence of a renal compartment syndrome as a consequence of ischemia-reperfusion injury. Surgical pressure relief effectively prevented functional and structural renal impairment, and we speculate that this approach might be of value for improving graft function after renal transplantation.

    2017-01-01

    Full Text Available Rhabdomyolysis is the result of skeletal muscle tissue injury and is characterized by elevated creatine kinase levels, muscle pain, and myoglobinuria. It is caused by crush injuries, hyperthermia, drugs, toxins, and abnormal metabolic states. This is often difficult to diagnose perioperatively and can result in renal failure and compartment syndrome if not promptly treated. We report a rare case of inadvertent rhabdomyolysis and compartment syndrome in a bodybuilder undergoing minimally invasive cardiac surgery. The presentation, differential diagnoses, and management are discussed. Hyperkalemia may be the first presenting sign. Early recognition and management are essential to prevent life-threatening complications.

    Compartment syndrome in the absence of fracture is rare and poorly described within the pediatric literature. The purpose of this study was to report the varying etiologies, risk factors, and treatment outcomes associated with pediatric nonfracture acute compartment syndrome (NFACS). We conducted a retrospective chart review on 37 children who suffered a NFACS and were treated at a single pediatric trauma center between 1997 and 2013. Demographic, diagnostic, treatment, and outcome characteristics were reviewed. Five causal groups were generated: trauma, exercise related (acute presentation after exercise without trauma), infectious, vascular, and postoperative (in the absence of osteotomy). Univariate and multivariate analyses were performed to identify risk factors of NFACS. P-values 39 cases of NFRCS in 37 children [6 females, 31 males, mean age of 11.7 y (SD+7.2 y)]. The leg was the most commonly involved limb (29 cases, 74%). Diagnosis of NFRCS was made either by compartment pressure monitoring [59%, 23/39 cases, mean pressure 66 mm Hg (SD+28)] or by clinical examination. According to etiology, vascular was most common (11/39, 28%), followed by trauma (10/39, 26%) and postoperative (8/39, 21%), with exertion and infection representing a small proportion (6/39, 15% and 4/39, 10%, respectively). Pain was present in 33 cases (85%), swelling in 28 cases (72%), paresthesias in 13 cases (33%), motor deficit in 12 cases (31%), and poor perfusion in 11 cases (28%). Average time from symptom onset to diagnosis was 48 hours (IQR, 9 to 96 h). At surgery, 21 patients (54%) had evidence of myonecrosis. Children required an average of 3 surgeries for wound closure.

    The abdominal compartment syndrome is a life threatening clinical entity which can develop within the first 12 hours of intensive care unit admission in high-risk surgical patients. The aim of this paper is to show the definitions, ethiology, pathophysiology, diagnosis and treatment of this serious, not only surgical problem. The mortality due to the abdominal compartment syndrome is extremely high (38-71%). It can be defined as adverse physiologic consequences that occur as a result of an acute increase in the intraabdominal pressure. The most common causes are retroperitoneal haemorrhage, visceral oedema, pancreatitis, bowel obstruction, tense ascites, peritonitis, tumor. The mostly affected systems are cardiovascular, pulmonary, renal, central nervous systems and splanchnic organs. The gold standard diagnostic method is the continuous intra-abdominal pressure monitoring. The treatment consists of adequate fluid resuscitation and surgical decompression. We show three typical short case reports treated by the above mentioned theories. Intraabdominal hypertension and abdominal compartment syndrome are frequent clinical findings among acute general surgical patients. Patients with comparable demographics and acute severity of illness are more likely to die if intraabdominal hypertension or abdominal compartment syndrome is present. We conclude that the early recognition and surgical decompression is urgent.

    Intestinal obstruction (IO) leads to increased intra-abdominal pressure and abdominal compartment syndrome. The purpose of this study was to investigate the characteristics of abdominal compartment syndrome in patients with IO secondary to strangulated hernia. We studied 81 consecutive unselected patients presenting complicated hernias and IO. We measured intra-abdominal pressure using the intra-vesicular pressure method. Preoperative (15 min) intra-abdominal pressure was higher in patients with strangulated hernias. Postoperative (15 min) intra-abdominal pressure in both groups decreased to similar values. Intra-abdominal pressure was measured during the preoperative period in patients with strangulated hernias and during the postoperative period at 15 min (13.8 +/- 6.4 mmHg), 24 h (9.8 +/- 3.2 mmHg) and 48 h (7.4 +/- 2.4 mmHg). Abdominal compartment syndrome developed in 47% cases with strangulated hernias with a mortality of five patients. Serial measurements of intra-abdominal pressure evidenced the clinical severity of strangulated hernia. Intra-abdominal pressure measurement may be used as a predictor of intestinal strangulation in patients presenting acute abdominal compartment syndrome secondary to complicated hernia.

    Full Text Available Chronic exertional compartment syndrome (CECS is a relatively rare condition that affects young adult athletes and often causes them to present to the emergency department. If left untreated, those who continue to compete at high levels may experience debilitating leg pain. Physicians may have difficulty differentiating CECS from other syndromes of the lower leg such as medial tibial stress syndrome, stress fractures, and popliteal artery entrapment. The gold standard for diagnosing CECS is intramuscular compartment pressure monitoring before and/or after 10 minutes of exercise. Some patients may choose to stop participation in sports in order to relieve their pain, which otherwise does not respond well to nonoperative treatments. In patients who wish to continue to participate in sports and live an active life, fasciotomy provides relief in 80% or more. The typical athlete can return to training in about 8 weeks. This is a case of a high school soccer player who stopped competing due to chronic exertional compartment syndrome. She had a fascial hernia, resting intramuscular pressure of 30 mmHg, and postexercise intramuscular pressure of 99 mmHg. Following fasciotomy she experienced considerable life improvement and is once again training and playing soccer without symptoms.

  6. A New Etiology for the Abdominal Compartment Syndrome: Pseudomyxoma Peritonei

    Directory of Open Access Journals (Sweden)

    Charles Sabbagh

    2015-09-01

    Full Text Available Pseudomyxoma peritonei (PMP is a rare diagnosis with an incidence of 1-2 per million. Most cases originate from an appendix which ruptures and releases mucin into the peritoneal cavity. The progression of the disease results in obstruction and cutaneous leak. Abdominal compartment syndrome is an uncommon complication of peritoneal pseudomyxoma. In the present article, we report the case of a patient with PMP and abdominal compartment syndrome. A laparotomy to decrease the abdominal pressure was performed. Three months later, a peritonectomy with hyperthermic intraperitoneal chemotherapy was performed. The patient was still alive 1 year after the procedure without any recurrence. In conclusion, acute abdominal pain and respiratory failure in patients with peritoneal PMP should lead to the measurement of the abdominal pressure but are not a contra indication for curative treatment of PMP.

    Abdominal compartment syndrome (ACS) is increasingly identified in critically ill patient and its harmful effects are well documented. The disparity among the pressure, volume in abdominal cavity and its contents, results in ACS. The actual incidence of ACS is not known. However, it has been observed predominantly in patients with severe blunt and penetrating abdominal trauma, ruptured abdominal aortic aneurysms, retro- and intra-peritoneal hemorrhage, pneumoperitoneum, neoplasm, pancreatitis, ascites and multiple bone fracture. We present a case of 40-year female who underwent emergency cesarean section and developed abdominal compartment syndrome due to urinary bladder distension secondary to blockade of urinary catheter with blood clots. This is a very unusual cause of ACS. (author)

  8. Compartment syndrome after total knee arthroplasty: regarding a clinical case

    Directory of Open Access Journals (Sweden)

    Ana Alexandra da Costa Pinheiro

    2015-08-01

    Full Text Available ABSTRACT Although compartment syndrome is a rare complication of total knee arthroplasty, it is one of the most devastating complications. It is defined as a situation of increased pressure within a closed osteofascial space that impairs the circulation and the functioning of the tissues inside this space, thereby leading to ischemia and tissue dysfunction. Here, a clinical case of a patient who was followed up in orthopedic outpatient consultations due to right gonarthrosis is presented. The patient had a history of arthroscopic meniscectomy and presented knee flexion of 10° before the operation, which consisted of total arthroplasty of the right knee. The operation seemed to be free from intercurrences, but the patient evolved with compartment syndrome of the ipsilateral leg after the operation. Since compartment syndrome is a true surgical emergency, early recognition and treatment of this condition through fasciotomy is crucial in order to avoid amputation, limb dysfunction, kidney failure and death. However, it may be difficult to make the diagnosis and cases may not be recognized if the cause of compartment syndrome is unusual or if the patient is under epidural analgesia and/or peripheral nerve block, which thus camouflages the main warning sign, i.e. disproportional pain. In addition, edema of the limb that underwent the intervention is common after total knee arthroplasty operations. This study presents a review of the literature and signals that the possible rarity of cases is probably due to failure to recognize this condition in a timely manner and to placing these patients in other diagnostic groups that are less likely, such as neuropraxia caused by using a tourniquet or peripheral nerve injury.

    Abdominal compartment syndrome is a systemic syndrome involving derangement in cardiovascular hemodynamics, respiratory and renal function as a result of sustained increase in intra-abdominal pressure. This results in multi-organ failure requiring prompt action and treatment. Presentation can be acute, chronic and acute on chronic. Initial diagnosis is clinical, confirmed by measurement of urinary bladder pressure. Treatment is abdominal decompression by laparostomy and delayed abdominal closure. Awareness among the surgeons has increased because laparoscopy has resulted in determination of intra-abdominal pressure as a readily measurable quantity. They have been able to appreciate the benefit of abdominal decompression by performing repeated planned laparotomies for trauma. (author)

Currently, such information is manually curated from the literature, obtained from high-throughput microscopy-based screens and predicted from primary sequence. To get a comprehensive view...... of the localization of a protein, it is thus necessary to consult multiple databases and prediction tools. To address this, we present the COMPARTMENTS resource, which integrates all sources listed above as well as the results of automatic text mining. The resource is automatically kept up to date with source...... databases, and all localization evidence is mapped onto common protein identifiers and Gene Ontology terms.

    Full Text Available A male patient in his fifties presented to his local hospital with numbness and weakness of the right leg which left him unable to mobilise. He reported injecting heroin the previous morning. Following an initial diagnosis of acute limb ischaemia the patient was transferred to a tertiary centre where Computed Tomography Angiography was reported as normal. Detailed neurological examination revealed weakness in hip flexion and extension (1/5 on the Medical Research Council scale with complete paralysis of muscle groups distal to this. Sensation to pinprick and light touch was globally reduced. Blood tests revealed acute kidney injury with raised creatinine kinase and the patient was treated for rhabdomyolysis. Orthopaedic referral was made the following day and a diagnosis of gluteal compartment syndrome (GCS was made. Emergency fasciotomy was performed 56 hours after the onset of symptoms. There was immediate neurological improvement following decompression and the patient was rehabilitated with complete nerve recovery and function at eight-week follow-up. This is the first documented case of full functional recovery following a delayed presentation of GCS with sciatic nerve palsy. We discuss the arguments for and against fasciotomy in cases of compartment syndrome with significant delay in presentation or diagnosis.

    The gold standard of quick and definitive treatment of Abdominal compartment syndrome (ACS) is surgical decompression by opening the abdomen and leaving it open until intra-abdominal pressure decreases. Temporary abdominal closure techniques are used to postpone definite closure until predisposing factors causing pathologic elevation of intra-abdominal pressure are resolved.This study aim to analyze feasibility of Bogota Bag placement as a way of temporary abdominal closure. Cases admitted in the period of eight years that were diagnosed to have or at risk to develop ACS and managed with 'Bogota Bag', irrespective of primary diagnosis were reviewed retrospectively. Cause of ACS, reasons to place Bogota bag, its complications and final outcome in terms of mortality related or not related with Bogota Bag placement were assessed. Total of ten patients had placement of Bogota Bag in the period of eight years. Laparotomy for bowel perforation with peritonitis was the most common primary condition contributing to ACS. Bogota bag was placed in two cases after emergency decompression as a therapeutic measure whereas others were done as prophylactic measure. There were two mortalities (20%) which were not directly related to abdominal compartment syndrome. Abdomen closure with Bogota Bag for patients with ACS or likely to develop ACS is a feasible technique with minimal procedure related morbidities.

    Widow spider envenomations generally produce systemic neurologic syndromes without significant local injury. We report a patient who sustained a black widow spider bite to the left forearm and presented to the emergency department with rhabdomyolysis and compartment syndrome. We documented a decrease in symptoms and compartment pressure after administration of antivenom. No surgical intervention was performed. We believe this report to be the first documenting compartment syndrome associated with black widow spider bite.

    Full Text Available Despite extensive review in the literature, compartment syndrome and crush syndrome remain difficult to diagnose. Trauma, toxins and reperfusion have been associated with these syndromes. Cases involving alcohol and drug abuse have described patients “found down” compressing an extremity. We present a case of a registered nurse who developed compartment syndrome in multiple limbs due to prolonged sleep after sleep deprivation and zolpidem use. To our knowledge, this is the first case of compartment syndrome or crush syndrome to have occurred in the setting of zolpidem use. Sleep disruption in healthcare workers represents a public health issue with dangerous sequelae, both acute and chronic.

    Acute compartment syndrome of the lower leg is usually associated with major trauma such as fracture, and most commonly occurs in the anterior or deep posterior compartments. Isolated lateral compartment syndrome is less typical and usually associated with minor trauma or exertion. There are a few reports of the acute compartment syndrome which develops without an obvious cause. However, there are few reports of idiopathic acute isolated lateral compartment syndrome, and there are no reports of the radiologic findings. This study presents a radiologic finding of idiopathic acute isolated lateral compartment of lower leg, which shows localized enlargement of the peroneal muscles with peripheral convex bowing and change of their signal intensity with fluid signal along the adjacent fascial planes on magnetic resonance imaging.

    2015-11-01

    Low back pain is extremely common and usually a minor self-limiting condition. Rarely, however, it is a harbinger of serious medical illness. Paraspinal compartment syndrome is a rare condition, but its timely recognition is important to allow adequate treatment. A 16-year-old boy presented to the Emergency Department (ED) with severe low back pain, necessitating intravenous opioids. Laboratory results showed severe rhabdomyolysis. Magnetic resonance imaging of the lumbar spine showed diffuse edema and swelling in the paraspinal muscles. Aggressive fluid therapy was started but despite narcotic analgesia the pain persisted and creatine kinase (CK) levels increased. Compartment pressures of the erector spinae were found to be increased. The decision was made to proceed with bilateral paraspinal fasciotomies. Postoperatively, the patient noted immediate pain relief with rapid decrease of CK level. The patient is pain free and resumed running and swimming 3 months after admission in the ED. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Although paraspinal compartment syndrome is a rare condition, its recognition is of paramount importance to allow adequate surgical treatment, preventing muscle necrosis. Although back pain most often has a benign course, a careful history and physical examination in patients presenting with low back pain allows determination of "red flags." Mandatory further diagnostic tests can identify underlying serious illness. Copyright © 2015 Elsevier Inc. All rights reserved.

  3. Extravasation of radiographic contrast material and compartment syndrome in the hand: a case report

    2011-02-01

    Full Text Available Abstract Radiocontrast agents are a type of medical contrast material used to improve the visibility of internal bodily structures in X-ray based imaging techniques such as computed tomography (CT or radiography. Radiocontrast agents are typically iodine or barium compounds. Extravasation of contrast is a possible complication of imaging studies performed with contrasts. Most extravasations cause minimal swelling or erythema, however, skin necrosis, ulceration and compartment syndrome may occur with extravasation of large volumes of contrast. A case report is presented in which significant extravasation of contrast was caused while injecting the contrast intravenously into the back of the hand of a 50 year old patient during computed tomography. The patient was undergoing chemotherapy. The patient developed a compartment syndrome and a fasciotomy was required. Treatment options are outlined and emphasis is made on prevention of this iatrogenic complication. Some of the preventive measures to avoid these complications include use of non-ionic contrast (low osmolarity, careful choice of the site of intravenous administration, and close monitoring of the patient during injection of contrast to minimize or prevent extravasation injuries. Clear information to patients and prompt recognition of the complication can allow for other non-surgical treatment options than the one required in this case.

  4. Evaluation of the relationship between pelvic fracture and abdominal compartment syndrome in traumatic patients

    Directory of Open Access Journals (Sweden)

    Sheikhi Rahim Ali

    2013-01-01

    Full Text Available Introduction: An increase in abdominal pressure can lead to so-called intra-abdominal compartment syndrome (ACS. Multiple factors such as an increase in retroperitoneal volume due to pancreatitis, bleeding and edema as a result of pelvic fracture can lead to compartment syndrome. Prevention is better than cure in compartment syndrome. By measuring the intra-abdominal pressure (IAP through the bladder, a quick and accurate assessment of abdominal pressure is achieved. Therefore, this study aimed to evaluate the relationship between pelvic fracture and ACS in traumatic patients. Materials and Methods: This research was a descriptive-analytical study conducted on 100 patients referring to the Shiraz Nemazee Hospital in 2010. IAP was monitored every 4 h in patients suspected to be at high risk for ACS, e.g., those undergoing severe abdominal trauma and pelvic fracture. The IAP was measured via the urinary bladder using the procedure described by Kron et al. Data collected were analyzed using SPSS software. Results: The findings showed that ACS occurred in 28 of 100 patients. With regard to the associated injuries with abdominal trauma, 19% of all patients and 46/42% of the patients with ACS had pelvic fracture. Chi-square test revealed a significant relationship between pelvic fracture and incidence rate of ACS ( P < 0.001. Conclusions: According to the collected data, pelvic fracture due to a trauma can be one of the important causes of an increase in IAP and ACS. In this lethal condition, prevention is better than cure. Therefore, serial measurement of IAP through the bladder in high-risk patients (those with pelvic fracture by trauma is recommended to the nurses to diagnose this condition and to decrease the incidence of mortality.

  5. Current concepts in the pathophysiology, evaluation, and diagnosis of compartment syndrome

    Hargens, A. R.; Mubarak, S. J.

    1998-01-01

    This article reviews present knowledge of the pathophysiology and diagnosis of acute compartment syndromes. Recent results using compression of legs in normal volunteers provide objective data concerning local pressure thresholds for neuromuscular dysfunction in the anterior compartment. Results with this model indicate that a progression of neuromuscular deficits occurs when IMP increases to within 35 to 40 mm Hg of diastolic blood pressure. These findings provide useful information on the diagnosis and compression thresholds for acute compartment syndromes. Time factors are also important, however, and usually are incompletely known in most cases of acute compartment syndrome. Although the slit catheter is a very good technique for monitoring IMP during rest, these catheters and their associated extracorporeal transducer systems are not ideal. Recently developed miniature transducer-tipped catheters and, perhaps, future development of noninvasive techniques may provide accurate recordings of IMP in patients with acute compartment syndromes.

    Although orbital compartment syndrome is a rare condition, it is still the most common cause of blindness following simple or complicated facial fractures. Its pathomechanism is similar to the compartment syndrome in the limb. Little extra fluid (blood, oedema, brain, foreign body) in a non-space yielding space results with increasingly higher pressures within a short period of time. Unless urgent surgical intervention is performed the blocked circulation of the central retinal artery will result irreversible ophthalmic nerve damage and blindness. Aim, material and method: A retrospective analysis of ten years, 2007-2017, in our hospital among those patients referred to us with facial-head trauma combined with blindness. 571 patients had fractures involving the orbit. 23 patients become blind from different reasons. The most common cause was orbital compartment syndrome in 17 patients; all had retrobulbar haematomas as well. 6 patients with retrobulbar haematoma did not develop compartment syndrome. Compartment syndrome was found among patient with extensive and minimal fractures such as with large and minimal haematomas. Early lateral canthotomy and decompression saved 7 patients from blindness. We can not predict and do not know why some patients develop orbital compartment syndrome. Compartment syndrome seems independent from fracture mechanism, comminution, dislocation, amount of orbital bleeding. All patients are in potential risk with midface fractures. We have a high suspicion that orbital compartment syndrome has been somehow missed out in the recommended textbooks of our medical universities and in the postgraduate trainings. Thus compartment syndrome is not recognized. Teaching, training and early surgical decompression is the only solution to save the blind eye. Orv Hetil. 2017; 158(36): 1410-1420.

    The aim of this study was to evaluate the use of MR imaging for diagnosis and therapy management of compartment syndromes. In total, 15 patients (5 with an imminent compartment syndrome and 10 with manifest compartment syndrome) underwent MR imaging with a variety of pulse sequences including fat suppression, magnetization transfer imaging, and intravenous gadopentetate dimeglumine (Gd-DTPA) administration. Early and late follow-up MR images were obtained. Manifest compartment syndromes showed swollen compartments with loss of normal muscle architecture on T1-weighted spin-echo images. T2-weighted spin-echo and magnetization transfer imaging showed bright areas, which enhanced after Gd-DTPA. Early follow-up showed changes in enhancement patterns; late follow-up showed fibrosis and cystic and fatty degenerations of the affected compartments. MR imaging can help make the diagnosis of a manifest compartment syndrome in clinically ambiguous cases. It points out the affected compartments and allows the surgeon to selectively split the fascial spaces. (orig.)

    Gluteal compartment syndrome is a very rare condition characterized by non-specific symptoms that often lead to misdiagnosis. We report a case of gluteal compartment syndrome in a 38 year-old Caucasian male (intravenous drug user) following prolonged immobilization due to loss of consciousness. The delay in the appropriate diagnosis and treatment led to a temporary acute kidney injury and to irreversible sciatic nerve palsy. Delay in the definitive diagnosis and treatment of gluteal compartment syndrome, may lead to higher morbidity of the affected extremity and in rare cases even patient mortality. Special emphasis is given to the aetiology, symptomatology, differential diagnosis as well as the treatment of this condition.

  10. Bilateral post-traumatic gluteal compartment syndrome: A case report and review of literature

    Full Text Available Gluteal compartment is a rare site for compartment syndrome. Gluteal compartment syndrome has most commonly been described in the literature as occurring after prolonged immobility associated with substance abuse, improper operative positioning, sickle cell-induced infarct, post-traumatic and spontaneous superior gluteal artery rupture, exercise, and post-arterial embolization of the internal iliac artery prior to abdominal aortic aneurysm repair. Trauma is rarely associated with this syndrome. Gluteal compartment syndrome occurs in approximately 0.9% of trauma patients. Posttraumatic gluteal compartment syndrome develops because of edema with traumatic contusions, crush injuries and hematoma formation due to blunt superior or inferior gluteal artery injuries in all compartments of the gluteal region Only 6 previous cases have been reported in the literature. Two previous cases involved positioning for urological procedures, while the other cited causes of bilateral gluteal compartment syndrome include exercise-induced, trauma, and prolonged immobilization from substance abuse. One of the most immediately devastating results of a missed compartment syndrome is the risk of the development of rhabdomyolysis with the resulting squeal of myoglobinuria, hyperkalemia, and acidosis resulting in renal failure, shock, multiple organ failure, disseminated intravascular coagulation, and possibly death. Here we report a case of posttraumatic bilateral compartment syndrome which developed secondary to pressure due to patient being trapped under a vehicle following a vehicular accident. He was operated upon and a bilateral fasciotomy was done. Although he did not develop any renal complications, the sciatic nerve palsy on the left side did not recover. The patient is still under follow up.

    Acute compartment syndrome affecting the gluteal region is rare when compared to the same condition in the forearm or calf. When it does occur, it is usually due to prolonged immobilisation in those with altered consciousness. Gluteal compartment syndrome resulting from injury to the superior gluteal artery is extremely rare and to our knowledge has been described only twice--both after high-energy road traffic accidents (RTA). Other cases have described profound hypotension with superior gluteal artery injury after an RTA and falling off a horse, without acute gluteal compartment syndrome. We present a case of gluteal compartment syndrome due to rupture of the superior gluteal artery following a relatively minor fall. The patient required an emergency fasciotomy, which was performed within 4 h of the injury. This case highlights the importance of early diagnosis and treatment of this rare condition.

    Chronic exertional compartment syndrome is a relatively rare condition among running athletes. In those who engage in repetitive activity, it can cause severe, debilitating leg pain. The diagnosis can be made with a thorough workup that includes history and physical examination, radiologic studies (x-rays, magnetic resonance imaging, bone scan), and compartment pressure monitoring. Most patients do not respond well to nonoperative intervention. Fasciotomy provides satisfactory relief of symptoms and helps patients return to their sports. We present the case of a high-level collegiate soccer player with chronic exertional compartment syndrome.

    Gluteal compartment syndrome is a relatively rare condition that mostly result from atraumatic causes such as prolonged immobilization due to drug abuse or alcoholic intoxication and incorrect positioning during surgical procedures rather than traumatic causes. Early diagnosis is difficult and sometimes delayed or overlooked because of poor physical signs resulting from altered mental status and inappropriate diagnosis by clinicians. It has been reported that more than half of the cases of gluteal compartment syndrome are associated with crush syndrome and sciatic nerve palsy. Early diagnosis and immediate fasciotomy are necessary to improve the functional prognosis. Here, we report the case of a patient with gluteal compartment syndrome caused by prolonged immobilization after acute alcoholic intoxication. After disease onset, the patient developed complications of crush syndrome and sciatic nerve palsy, but immediate fasciotomy improved his condition.

    Objective. A prospective descriptive study to determine the value of magnetic resonance imaging (MRI) as an aid in diagnosing (chronic) exertional compartment syndrome.Design and patients. MRI was performed in 21 patients (41 anterior compartments) with chronic compartment syndrome at rest and following physical exercise. Median (T2-weighted) signal intensity on the MRI scan was determined in the anterior and the (superficial) posterior compartment of the lower leg before and after exercise. Postexercise increases in the signal intensity in these two compartments were compared. After fasciotomy, a second MRI scan was performed in 13 patients (25 anterior compartments) on the basis of the same protocol. MR studies were performed in 12 normal controls (24 anterior muscle compartments) on the basis of the same protocol.Results. T{sub 2}-weighted signal intensity increased by 27.5% (range 13.6-38.6%) following exercise in the anterior compartment of patients with a chronic compartment syndrome. In the posterior compartment this increase amounted to 4.25% (range 0-10.2%). Following fasciotomy, the increase in the anterior compartment was 4.1% (range 1.0-5.2%), while the increase in the posterior compartment amounted to 5.6% (range 0-11.0%), In normal controls, the increase in the anterior compartment was 7.6% (range 0-9.1%), while in the posterior compartment it was 4.0% (range 0-7.2%).Conclusions. In patients with a chronic compartment syndrome, the affected (anterior) compartment shows a statistically significant increase in (T2-weighted) signal intensity during exercise compared with both the (superficial) posterior compartment and the anterior compartment of normal controls. This effect disappeared after fasciotomy. In view of the substantial increase in T2-weighted signal intensity, MRI can be used in diagnosing chronic compartment syndrome. (orig.)

    Full Text Available Abstract Background Prompt diagnosis and decompression of acute lower extremity compartment syndrome (LECS in the multisystem injured patient is essential to avoid the devastating complications of progressive tissue necrosis and amputation. Despite collaborative trauma and orthopedic management of these difficult cases, significant delays in diagnosis and treatment occur. Periodic system review of our trauma and orthopedic data for complications of LECS led us to hypothesize that delayed diagnosis and limb loss were potentially preventable events in our trauma center. Setting Academic level 1 trauma center. Methods We performed a prospective review of our trauma registry for all cases of LECS over a 7 year period (2/98–10/2005. Variables reviewed included demographics, injury patterns, tissue necrosis, amputation and mortality. Results Eighty-three (10 female, 73 male cases were reviewed. Mean age = 33.3 years (range 1–78. Mean ISS = 19.4, GCS = 12.5. Five (6.0% had amputations; 7 (8.4% died. Fractures occurred in 68.7% (n = 57, and vascular injuries were present in 38.6% (n = 32. In 7 patients (8.4%, a delayed compartment release resulted in muscle necrosis requiring multiple debridements, subsequent wound closure problems, and long term disability. Of note, none of these patients had prior compartment pressure measurements. Furthermore, 6 patients (7% had superficial peroneal nerve transections as complications of their fasciotomy. Conclusion In the multisystem injured patient, LECS remains a major diagnostic and treatment challenge with significant risks of limb loss as well as complications from decompressive fasciotomy. These data underscore the importance of routine surveillance for LECS. In addition, a thorough knowledge of regional anatomy is essential to avoid technical morbidity.

  2. Acute Compartment Syndrome after an Olecranon Fracture in a Patient with Mild Hemophilia B

    Reynolds, John M; Christophersen, Christy; Mulcahey, Mary K

    2017-01-01

    Introduction: Compartment syndrome is a serious condition characterized by compartmental pressures within 20 mmHg of diastolic blood pressure, or clinical signs of pain, paresthesia, pallor, and lack of pulses. Often a surgical intervention is necessary. Increased surveillance for compartment syndrome is important when a patient with a bleeding disorder sustains a traumatic injury. Case Report: We present a case of forearm compartment syndrome in a patient with mild hemophilia B who sustained an olecranon fracture. The patient received factor replacement and he underwent emergent forearm fasciotomies to avoid muscle necrosis. Over the subsequent week, the patient returned to the operating room 3 times for repeat irrigation and debridements, partial wound closure, open reduction internal fixation of his olecranon fracture and eventual skin grafting of the volar forearm wound. Conclusion: Failure to recognize compartment syndrome in even mild forms of hemophilia may result in loss of function, neurologic deficits, and limb amputations. The management of acute compartment syndrome in patients with hemophilia requires timely recognition, replacement of clotting factors, and emergent fasciotomies. PMID:28819614

    Liver compartment syndrome is a life-threatening complication of hepatic subcapsular hematoma; diagnosis and assessment of treatment effects are therefore important. We report a rare case of liver compartment syndrome due to spontaneous hepatic subcapsular hematoma without any underlying conditions, in which Doppler ultrasonography (US) proved useful in both diagnosis and assessment of treatment effects. A 32-year-old woman experienced sudden epigastralgia and was diagnosed with hepatic subcapsular hematoma in the right lobe, based on contrast-enhanced computed tomography. Hepatic arteriography showed active hemorrhage and Doppler US showed retrograde flow in the right portal vein. From these findings, we diagnosed hepatic subcapsular hematoma complicated with liver compartment syndrome, and performed embolization of the bleeding point and percutaneous hematoma drainage. After these medical procedures, normalized antegrade flow in the right portal vein was observed on Doppler US. No underlying conditions contributing to hematoma were identified. In this case, Doppler US was useful for both diagnosis and assessment of treatment effects in liver compartment syndrome. When we examine patients with hepatic subcapsular hematoma, Doppler US should be used to diagnose the presence of liver compartment syndrome and assess treatment effects.

    Changes in aircraft cabin pressure and its interplay with a fixed diameter fiberglass cylindrical cast and the closed air cells in waterproof cast padding may cause a transient altitude-induced compartment syndrome. In this case series, 2 patients reported transient compartment syndromes that resolved with aircraft decent. As proof of concept, this work displays photographic and video evidence showing the difference in air cell volume from experimental data in a vacuum chamber as well as real-world volume changes at cruise altitude in a commercial airliner. Transient altitude-induced compartment syndromes associated with fiberglass casts using waterproof cast padding are real and surgeons and patients should be advised of this potentially devastating complication.

    Acute lumbosacral plexus injury from gluteal compartment syndrome is extremely rare. Physicians should be aware of this diagnosis when examining patients with altered mental status, prolonged immobilization, and gluteal muscle compression. This case report presents a patient with acute complete left lumbosacral plexus paralysis and acute renal failure after gluteal compartment syndrome secondary to prolonged immobilization from drug abuse. Clinical examination, imaging of the pelvis, renal function, creatine phosphokinase, and urine myoglobin were indicative of gluteal compartment syndrome and rhabdomyolysis. Electrodiagnostic studies showed complete limb paralysis. Medical treatment and rehabilitation was administered. Renal function recovered within the 1st week; function at the proximal muscles of the left lower limb improved within 6 months, with mild discomfort on sitting at the buttock, foot drop, and sensory deficits at the leg and dorsum of foot.

    Management of the abdominal compartment syndrome during severe acute pancreatitis by the open abdomen method is associated with considerable morbidity and resource utilization. Thus, the aim of this study was to evaluate the safety and efficacy of the ultrasound-guided percutaneous interventions and/or minimally invasive surgery in the treatment of abdominal compartment syndrome. Forty-four patients with severe acute pancreatitis were enrolled into a prospective study and treated according to the standard management protocol. Interventional and/or surgical management of abdominal compartment syndrome was employed in 6 (13.6%) cases. In the context of this study, we assessed the feasibility and effectiveness of subcutaneous fasciotomy of the anterior m. rectus abdominis sheath, as well as the role of ultrasound-guided drainage of intra-abdominal and peripancreatic fluid collections in the management of abdominal compartment syndrome. Subcutaneous fasciotomy of the anterior m. rectus sheath and ultrasound-guided drainage of intra-abdominal and peripancreatic fluid collections seem to be safe (minor risk of bleeding or infection, closed abdomen, and easy care for the patient) and effective (resulted in a sustained decrease of intra-abdominal pressure to 13-16 mm Hg and regression of organ failures after intervention). Subcutaneous anterior m. rectus fasciotomy may appear to be beneficial in case of refractory abdominal compartment syndrome avoiding morbidity associated with the open abdomen technique. Both the subcutaneous fasciotomy and ultrasound-guided drainage of intra-abdominal and/or peripancreatic fluid collections seem to be safe and effective alternatives in the management of abdominal compartment syndrome; however, prospective studies are needed to further evaluate their clinical role.

    Acute limb compartment syndrome, a complication of musculoskeletal trauma, results in muscle necrosis and cell death. Carbon monoxide, liberated from the carbon monoxide-releasing molecule-3, has been shown protective in a rat model of compartment syndrome. The purpose of this study was to test the effect of carbon monoxide-releasing molecule-3 in a preclinical large animal model of compartment syndrome, with the ultimate goal of developing a pharmacologic adjunct treatment for compartment syndrome. Animal research study. Basic research laboratory in a hospital setting. Male Yorkshire-Landrace pigs (50-60 kg). Pigs underwent 6 hours of intracompartmental pressure elevation by infusing fluid into the anterior compartment of the right hind limb. Carbon monoxide-releasing molecule-3 was administered systemically (2 mg/kg, IV) at fasciotomy, followed by 3-hour reperfusion. Muscle perfusion, inflammation, injury, and apoptosis were assessed in the skeletal muscle. Systemic leukocyte activation was assessed during compartment syndrome and reperfusion. Elevation of hind limb intracompartmental pressure resulted in significant microvascular perfusion deficits (44% ± 1% continuously perfused capillaries in compartment syndrome vs 76% ± 4% in sham; p molecule-3 at fasciotomy increased the number of continuously perfused capillaries (68% ± 3%; p molecule-3 at fasciotomy offered protection against compartment syndrome-induced microvascular perfusion deficit, tissue injury, and systemic leukocyte activation. The data suggest the potential therapeutic application of carbon monoxide-releasing molecule-3 to patients at risk of developing compartment syndrome.

    2013-01-01

    Acute compartment syndrome, a surgical emergency, is defined as increased pressure in an osseofascial space. The resulting reduction of capillary perfusion to that compartment requires prompt fasciotomy. Treatment delay has a poor prognosis, and is associated with muscle and nerve ischemia, resultant infarction, and late-onset contractures. We report a case of traumatic bilateral upper limb acute compartment syndrome associated with anabolic steroids, requiring bilateral emergency fasciotomies. A 25-year-old male bodybuilder taking anabolic steroids, with no past medical history, presented to the Emergency Department 25 min after a road traffic accident. Secondary survey confirmed injuries to both upper limbs with no distal neurovascular deficit. Plain radiographs demonstrated bilateral metaphyseal fractures of the distal humeri. Within 2 h of the accident, the patient developed clinical features that were consistent with bilateral upper arm compartment syndrome. Bilateral fasciotomies of both anterior and posterior compartments were performed, confirming clinical suspicion. We suggest consideration of a history of anabolic steroid use when evaluating patients with extremity trauma. Copyright © 2013 Elsevier Inc. All rights reserved.

    We present the case of a young man with a 48 h delayed presentation of bilateral lower limb acute compartment syndrome (ACS) affecting the anterior compartments following an extended period of dancing at a music festival. On making the diagnosis of ACS, the patient was immediately taken to theatre for fasciotomies and compartmental decompression. Repeat look fasciotomies revealed further necrosis to the muscles of the anterior compartments bilaterally and, effectively, all the muscle bellies within the anterior compartments were excised. The patient has been left with a significant functional deficit and disability. This case highlights the importance of timely diagnosis of ACS as delay in presentation can impact significantly on subsequent functional outcome and quality of life. 2015 BMJ Publishing Group Ltd.

    2010-07-01

    Full Text Available Abstract Systemic Capillary Leak Syndrome (SCLS is a rare disorder characterized by increased capillary hyperpermeability leading to hypovolemic shock due to a markedly increased shift of fluid and protein from the intravascular to the interstitial space. Hemoconcentration, hypoalbuminemia and a monoclonal gammopathy are characteristic laboratory findings. Here we present a patient who suffered from SCLS with hypovolemic shock and compartment syndrome of both lower legs and thighs. Volume and catecholamine management was guided using transpulmonary thermodilution. Extended hemodynamic monitoring for volume and catecholamine management as well as monitoring of muscle compartment pressure is of crucial importance in SCLS patients.

    Aims Identifying predictors of compartment syndrome in the foot after a fracture of the calcaneus may lead to earlier diagnosis and treatment. The aim of our study was to identify any such predictors. Patients and Methods We retrospectively reviewed 303 patients (313 fractures) with a fracture of the calcaneus who presented to us between October 2008 and September 2016. The presence of compartment syndrome and potential predictors were identified by reviewing their medical records. Potential predictors included age, gender, concomitant foot injury, mechanism of injury, fracture classification, time from injury to admission, underlying illness, use of anticoagulant/antiplatelet agents, smoking status and occupation. Associations with predictors were analyzed using logistic regression analysis. Results Of the 313 fractures of the calcaneus, 12 (3.8%) developed a compartment syndrome. A Sanders type IV fracture was the only strongly associated factor (odds ratio 21.67, p = 0.007). Other variables did not reach statistical significance. Conclusion A Sanders type IV fracture is the best predictor of compartment syndrome after a fracture of the calcaneus. Cite this article: Bone Joint J 2018;100-B:303-8.

    Rhabdomyolysis often occurs after traumatic compartment syndrome, and high morbidity and mortality have been reported with the acute kidney injury that develops subsequently. We focused on the risk factors for rhabdomyolysis and acute kidney injury in patients with traumatic compartment syndrome. We also analyzed the relation between renal function and rhabdomyolysis in these patients. A retrospective chart review was conducted from January 2006 to March 2012. Inpatients with traumatic compartment syndrome were included. We evaluated patients' demographics, history of illicit drugs use or alcohol consumption, mechanism of injury, symptoms, serum creatine kinase levels, and kidney function. A total of 52 patients with a mean age of 40.9 years were included; 23 patients had rhabdomyolysis (44.2%), of which 9 patients developed acute kidney injury (39.1%). Significant predictive factors for rhabdomyolysis were history of illicit drugs or alcohol use (P=0.039; odds ratio, 5.91) and ischemic injury (P=0.005). We found a moderate correlation between serum creatine kinase levels and serum creatinine levels (R=0.57; PRhabdomyolysis was a predisposing factor for acute kidney injury (P=0.011; odds ratio, 8.68). Four patients with rhabdomyolysis required a short period of renal replacement therapy. A high percentage of patients with traumatic compartment syndrome developed rhabdomyolysis (44.2%). Patients with rhabdomyolysis had a higher possibility of developing acute kidney injury (39.1%), and rhabdomyolysis was correlated to renal function. Early diagnosis, frequent monitoring, and aggressive treatment are suggested once compartment syndrome is suspected. The overall prognosis is good with early diagnosis and proper treatment.

    2011-01-01

    The purpose of this project was to study the efficacy of quantitative muscle hardness (QH) curve analysis for noninvasive measurement of muscle compartment interstitial pressure (IMP), and to eliminate the need for a comparison normal QH measurement to determine a pathologic reading. Elevation of IMP may lead to limb compartment syndrome, which may result in irreversible dysfunction, chronic pain and contracture. Two studies were performed by two separate independent examiners on male volunteers, where IMP measurements and QH curves were obtained. QH curves were divided into three parts comparing the third part to the second part using the coefficient of determination (R 2 ). In 205 limb compartments, there were 1432 comparison readings of the IMP versus R 2 . Using receiver operator characteristic curve analysis for all data from both studies, an R 2 cutoff of 0.974 best corresponded to a pathologic IMP of 50 mmHg. For both sets of data and for each compartment tested, the mean IMP values were statistically different (t-test: P < 0.0001) for the group with R 2 values less than 0.974 compared to the group of R 2 values greater than or equal to 0.974. In addition, a pressure prediction model was formulated with a strong overall correlation coefficient of 0.78. The data of this study support that QH analysis is potentially useful for the monitoring of IMP elevation in compartment syndrome

    A 15-year-old female competitive high school basketball player presented as an outpatient with a 3-month history of bilateral exertional calf pain. Patient history and compartment pressure measurements were consistent with the diagnosis of chronic exertional compartment syndrome, and the patient underwent bilateral fasciotomies. Postoperatively, her symptoms recurred and she was found to have a deficient posterior tibial arterial system bilaterally, as confirmed on advanced imaging. We advocate the careful consideration of vascular etiologies in athletes who present with exertional leg pain.

    This study examined the effect of exposures to hyperbaric oxygen on the development of the edema and necrosis of muscle that are associated with compartment syndromes that are complicated by hemorrhagic hypotension. A compartment syndrome (twenty millimeters of mercury for six hours) was induced by infusion of autologous plasma in the anterolateral compartment of the left hind limb of seven anesthetized dogs while the mean arterial blood pressure was maintained at sixty-five millimeters of mercury after 30 per cent loss of blood volume. These dogs were treated with hyperbaric oxygen (two atmospheres of pure oxygen) and were compared with six dogs that had an identical compartment syndrome and hypotensive condition but were not exposed to hyperbaric oxygen. Forty-eight hours later, edema was quantified by measuring the weights of the muscles (the pressurized muscle compared with the contralateral muscle), and necrosis of muscle was evaluated by measuring the uptake of technetium-99m stannous pyrophosphate. The ratio for edema was significantly (p = 0.01) greater in dogs that had not been exposed to hyperbaric oxygen (1.15 +/- 0.01) than in the dogs that had been treated with hyperbaric oxygen (1.01 +/- 0.03), and the ratio for necrosis of muscle was also significantly (p = 0.04) greater in dogs that had not had hyperbaric oxygen (1.96 +/- 0.41) than in those that had been treated with hyperbaric oxygen (1.05 +/- 0.11). Comparisons were also made with the muscles of four normal control dogs and separately with the muscles of six normotensive dogs that had an identical compartment syndrome and normal blood pressure and were not treated with hyperbaric oxygen

    Abdominal compartment syndrome (ACS) is defined as an increase of intra-abdominal pressure (IAH) to values higher than 20 mmHg, associated with reduced perfusion and organ dysfunction. There is a classification of open abdomen which stratifies patients according to the natural history of improvement or clinical deterioration. The aim of treatment is to maintain the open abdomen at the lowest level and to prevent progression to a more complex level. Surgical treatment essentially consists in abdominal decompression by leaving the abdomen open. Analysis of the literature shows that negative pressure increases the rate of primary fascial closure; entero-cutaneous fistulas are seen in a minority of cases, without seeming consequence of the application of the dressing. Open abdomen management consists of three treatment stages: acute (24-48 hours), intermediate (from 48 hours to 10 days) and late or reconstruction (from 10 days to the final closure). It's important to recognize patients at risk of IAH and the first signs of ACS and intervene early with abdominal decompression if this will establish itself. Management of the open abdomen is now facilitated by negative pressure devices, which positively affect the morbidity and mortality of patients with ACS.

    Full Text Available Bilateral gluteal compartment syndrome is a rare clinical entity that can be complicated by rhabdomyolysis or acute kidney injury (AKI. We report the a case of a 30-year-old woman without any comorbid diseases who was diagnosed with bilateral gluteal compartment syndrome complicated by rhabdomyolysis and dialysis-requiring AKI, which was caused by prolonged immobilization under the influence of alcohol. Although the patient’s renal function recovered fully after 5 sessions of hemodialysis, sciatic neuropathy caused by gluteal compartment syndrome led to permanent foot drop.

    To present the diagnostic and clinical features including management of acute compartment syndrome (ACS) of the foot and to create a sense of emergency amongst clinicians of this rare and dangerous condition. A 28-year old male soccer player on acetylsalicylic acid (ASA) and verapamil presented with severe swelling, paresthesia, and pain in the left ankle after an acute grade three-inversion ankle sprain. A diagnosis of foot compartment syndrome was made. A fasciotomy was not performed and subsequent neurological sequelae occurred. We hypothesize that the edema caused by the ankle sprain was excessive due to the use of ASA and verapamil, resulting in increased compartmental pressure and neurological signs in the foot. Although rare, it is extremely important to be aware of the clinical features of ACS of the foot to obtain an appropriate diagnosis and manage this medical emergency promptly.

    2016-01-01

    To report the efficacy of intravenous mannitol in the treatment of orbital compartment syndrome. An experimental study was conducted on 4 nonhuman primates (8 orbits). Orbital compartment syndrome was simulated by injecting autologous blood into both orbits of each nonhuman primate until a pressure of 80 mm Hg was reached (time 0). After 10 minutes, nonhuman primates were randomized to receive an infusion of either mannitol or saline, given over 15 minutes. Five minutes after the infusion was complete, lateral canthotomy and cantholysis was performed on both orbits in isolated steps every 5 minutes. During the study protocol, orbital and intraocular pressures were recorded every 5 minutes, with a final set of measurements at 60 minutes. The primary outcome measures were the mean change in pressure from time 0 to 60 minutes, as well as the mean change in pressure during the infusion period. There was no statistically significant difference in the mean changes in orbital or intraocular pressure from time 0 to 60 minutes of the protocol. However, during the infusion period there was significantly greater decrease in both orbital and intraocular pressure in the mannitol compared with saline group (-34.0 vs. -9.3 mm Hg for orbital pressure [p = 0.03]; -34.8 vs. -9.7 mm Hg for intraocular pressure [p = 0.04]). While the definitive treatment of orbital compartment syndrome is lateral canthotomy and cantholysis, mannitol results in a rapid and clinically meaningful drop in orbital and intraocular pressure. The authors believe that their data support the routine use of mannitol in orbital compartment syndrome, especially when there is a delay in timely surgical management.

    To summarize early diagnosis and treatment methods of 20 patients with compartment syndrome caused by landslides during coal mine accidents in order to improve the level of diagnosis and treatment of compartment syndrome and reduce disability. From September 2006 to April 2010,20 patients with compartment syndrome were treated with the methods of early decompression, systemic support. All the patients were male with an average age of 42 years (ranged, 23 to 54). All the patients with high tension limb swelling, pain, referred pain passive positive; 5 extremities feeling diminish or disappear and the distal blood vessel beat were normal or weakened or disappeared; myoglobinuria, hyperkalemia, serum urea nitrogen and creatinine increased in 5 cases and oliguria in occurred 1 case. The function of affected limbs was observed according to disability ratings. Three cases complicated with infection of affected limb and 6 cases occurred with renal function insufficiency. Total recovery was in 16 cases, basically recovery in 3, amputation in 1 case. All patients were followed up for 6-15 months with an average of 12 months. The ability to work according to national standard identification--Employee work-related injuries and occupational disability rating classification (GB/T16180-2006) to assess, grade 5 was in 1 case, grade 8 in 2 cases, grade 10 in 1 case, no grade in 16 cases. Arteriopalmus of dorsalis pedis weaken and vanished can not be regard as an evidence in early diagnosis of compartment syndrome. Early diagnosis and decompression, systemic support and treatment is the key in reducing disability.

    Full Text Available Abstract Introduction A perforation occurring during colonoscopy is an extremely rare complication that may be difficult to diagnose. It can be responsible for acute abdominal compartment syndrome, a potentially lethal complex pathological state in which an acute increase in intra-abdominal pressure may provoke the failure of several organ systems. Case presentation We report a case of acute abdominal compartment syndrome after perforation of the bowel during a colonoscopy in a 60-year-old North African man with rectal cancer, resulting in respiratory distress, cyanosis and cardiac arrest. Our patient was treated by needle decompression after the failure of cardiopulmonary resuscitation. An emergency laparotomy with anterior resection, including the perforated sigmoid colon, was then performed followed by immediate anastomosis. Our patient remains alive and free of disease three years later. Conclusion Acute abdominal compartment syndrome is a rare disease that may occasionally occur after a colonoscopic perforation. It should be kept in mind during colonoscopy, especially considering its simple salvage treatment.

  9. Clinical and functional outcomes of acute lower extremity compartment syndrome at a Major Trauma Hospital.

    Acute lower extremity compartment syndrome (CS) is a condition that untreated causes irreversible nerve and muscle ischemia. Treatment by decompression fasciotomy without delay prevents permanent disability. The use of intracompartmental pressure (iCP) measurement in uncertain situations aids in diagnosis of severe leg pain. As an infrequent complication of lower extremity trauma, consequences of CS include chronic pain, nerve injury, and contractures. The purpose of this study was to observe the clinical and functional outcomes for patients with lower extremity CS after fasciotomy. Retrospective chart analysis for patients with a discharge diagnosis of CS was performed. Physical demographics, employment status, activity at time of injury, injury severity score, fracture types, pain scores, hours to fasciotomy, iCP, serum creatine kinase levels, wound treatment regimen, length of hospital stay, and discharge facility were collected. Lower extremity neurologic examination, pain scores, orthopedic complications, and employment status at 30 days and 12 months after discharge were noted. One hundred twenty-four patients were enrolled in this study. One hundred and eight patients were assessed at 12 months. Eighty-one percent were male. Motorized vehicles caused 51% of injuries in males. Forty-one percent of injuries were tibia fractures. Acute kidney injury occurred in 2.4%. Mean peak serum creatine kinase levels were 58,600 units/ml. Gauze dressing was used in 78.9% of nonfracture patients and negative pressure wound vacuum therapy in 78.2% of fracture patients. About 21.6% of patients with CS had prior surgery. Nearly 12.9% of patients required leg amputation. Around 81.8% of amputees were male. Sixty-seven percent of amputees had associated vascular injuries. Foot numbness occurred in 20.5% of patients and drop foot palsy in 18.2%. Osteomyelitis developed in 10.2% of patients and fracture nonunion in 6.8%. About 14.7% of patients underwent further orthopedic surgery

    Full Text Available Hypocalcemia most frequently occurs in premature neonates. It is usually treated by intravenous (iv calcium supplementation. However, complications caused by extravasation of iv calcium gluconate include localized soft tissue calcification, necrosis, cellulitis, osteomyelitis, and even compartment syndrome. We present a rare case of iatrogenic calcinosis cutis complicated by compartment syndrome secondary to extravasation of iv calcium gluconate in a neonate. Emergent fasciotomy was performed twice for decompression of compartment syndrome. Histologic findings revealed necrosis and calcification. Appropriate antibiotics were administered to control secondary infection. To the best of our knowledge, there were no previous case reports of calcinosis cutis with compartment syndrome in infants. Although iatrogenic calcinosis cutis is generally a benign entity, the early recognition of the presentation of extravasation of calcium gluconate is important to avoid severe complications and possible medical malpractice disputes. This report aims to raise doctors' awareness of the presentation, course, and management of this relatively rare iatrogenic complication.

    High-energy proximal tibial fractures often accompany compartment syndrome and are usually treated by fasciotomy with external fixation followed by secondary plating. However, the initial soft tissue injury may affect bony union, the fasciotomy incision or external fixator pin sites may lead to postoperative wound infections, and the staged procedure itself may adversely affect lower limb function. We assess the results of staged minimally invasive plate osteosynthesis (MIPO) for proximal tibial fractures with acute compartment syndrome. Twenty-eight patients with proximal tibial fractures accompanied by acute compartment syndrome who underwent staged MIPO and had a minimum of 12 months follow-up were enrolled. According to the AO/OTA classification, 6 were 41-A, 15 were 41-C, 2 were 42-A and 5 were 42-C fractures; this included 6 cases of open fractures. Immediate fasciotomy was performed once compartment syndrome was diagnosed and stabilization of the fracture followed using external fixation. After the soft tissue condition normalized, internal conversion with MIPO was done on an average of 37 days (range, 9-158) after index trauma. At the time of internal conversion, the external fixator pin site grades were 0 in 3 cases, 1 in 12 cases, 2 in 10 cases and 3 in 3 cases, as described by Dahl. Radiographic assessment of bony union and alignment and a functional assessment using the Knee Society Score and American Orthopedic Foot and Ankle Society (AOFAS) score were carried out. Twenty-six cases achieved primary bony union at an average of 18.5 weeks. Two cases of nonunion healed after autogenous bone grafting. The mean Knee Society Score and the AOFAS score were 95 and 95.3 respectively, at last follow-up. Complications included 1 case of osteomyelitis in a patient with a grade IIIC open fracture and 1 case of malunion caused by delayed MIPO due to poor wound conditions. Duration of external fixation and the external fixator pin site grade were not related to the

    Compartment syndrome of the upper extremity is a surgical emergency that, when left untreated, can have dire consequences. Its causes are numerous, one of which is the uncommon entity hereditary angioedema, an autosomal dominant disease resulting in edema in a variety of potential locations, including the extremities. This is only the second time hereditary angioedema has been mentioned in the literature as a cause of compartment syndrome. We present a case of hereditary angioedema leading to hand and forearm compartment syndrome in a 13-year-old pediatric patient. Diagnosis of hereditary angioedema was made by our Rheumatology colleagues with physical exam and a thorough history, and confirmed by laboratory studies. Our patient presented with compartment syndrome of the hand and forearm and underwent hand and volar forearm fasciotomies. She was subsequently worked up for hereditary angioedema with laboratory results confirming the diagnosis. She was discharged after a 5-day hospitalization with prophylactic C1-inhibitor therapy. Hereditary angioedema is a rare but known cause of compartment syndrome of the upper extremity, and must be considered when patients present with compartment syndrome of unknown etiology. This disease can be diagnosed by laboratory studies and symptoms can be controlled with medical therapy.

    In our recent clinical study of damage control laparotomy, the abdominal compartment syndrome (ACS) emerged as an independent risk factor for postinjury multiple organ failure (MOF). We and others have shown previously that the ACS promotes the systemic production of proinflammatory cytokines. Our study objective was to develop a clinically relevant two-event animal model of postinjury MOF using the ACS as a second insult during systemic neutrophil priming to provoke organ dysfunction. Male adult rats underwent hemorrhagic shock (30 mmHg x 45 min) and were resuscitated with crystalloids and shed blood. The timing of postshock systemic neutrophil (PMN) priming was determined by the surface expression of CD11b via flow cytometry. Finding maximal PMN priming at 8 h, but no priming at 2 h (early) and 18 h (late), the ACS (25 mmHg x 60 min) was introduced at these time points. At 24 h postshock, lung injury was assessed by lung elastase concentration and Evans blue dye extravasation in bronchoalveolar lavage. Liver and renal injuries were determined by serum alanine aminotransferase, serum creatinine, and blood urea nitrogen. The ACS during the time of maximal systemic PMN priming (8 h) provoked lung and liver injury, but did not if introduced at 2 or 18 h postshock when there was no evidence of systemic PMN priming. The 24-h mortality of this two-event model was 33%. These findings corroborate the potential for the ACS to promote multiple organ injury when occurring at the time of systemic PMN priming. This clinically relevant two-event animal model of PMN organ injury may be useful in elucidating therapy strategies to prevent postinjury MOF.

    2018-04-04

    In a 31-year-old man, the diagnosis of medial compartment syndrome of foot was delayed for 8 days. In contrast to previously reported cases, the patient presented with mainly bilateral lateral thigh-referred pain rather than foot pain. Although delayed decompression of the medial compartment provided dramatic relief of the referred pain, the patient complained of sensory deficit at the medial side of the foot and flexion deformity of the great toe at the final follow-up visit. Medial compartment syndrome of the foot can cause referred pain, and delayed or missed diagnosis can cause irreversible damage. Therefore, prompt diagnosis of compartment syndrome is crucial, and clinicians must consider the possibility of referred pain when the origin of pain is uncertain.

    Malhotra R

    2016-11-01

    Full Text Available We present a case of a lower limb compartment syndrome associated with the use of an intra-osseous line inserted into the proximal tibia in an adult patient. An unconscious 59-year old male with multiple injuries presented to our Emergency Department after a road traffic accident. Bilateral proximal tibial intra osseous-lines were inserted due to poor venous access. After resuscitation his left leg was noted to be tense and swollen with absent pulses. Acute compartment syndrome was diagnosed both clinically and with compartment pressure measurement. Two incision fasciotomy on his left lower leg was performed. Intra osseous-lines in the proximal tibia are increasingly used in adult patients in the pre-hospital setting by paramedics and emergency physicians. Their use, along with the possible complications of these devices, such as the development of compartment syndrome or osteomyelitis leading to amputation, is well reported in the paediatric literature. To the best of our knowledge, there have not been any previous reports of complications in the adult patient. We present a case of lower leg compartment syndrome developing from the use of an intra-osseous line in the proximal tibia in an adult patient. With the increasing use of intra-osseous lines in adult patients, clinicians should be aware of the possibility of developing compartment syndrome which may lead to disability or amputation in severe cases.

    1989-07-01

    A three-month-old male infant with undiagnosed hemophilia presented with fever and irritability. During the diagnostic evaluation a venipuncture in the right antecubital fossa led to hemorrhage and a compartment syndrome in the brachium. Differential diagnosis included osteomyelitis and septic arthritis but a 99technetium bone scan revealed only delayed washout of radioactive material from the right brachium without increased uptake. Despite elevated pressures in the muscle compartments of the right arm, surgical decompression was delayed until a complete blood coagulation profile was obtained. After replacement of deficient blood products, the compartment syndrome resolved without surgical decompression. Defective coagulation leading to hemorrhage into the muscle compartments of the arm resulted in a significant elevation of compartmental pressure. The unusual clinical presentation of the patient, as well as a lack of a positive family history, delayed the diagnosis of hemophilia and the subsequent replacement therapy.

    2016-01-01

    Acute compartment syndrome (ACS) involving the leg can occur in association with various traumatic and nontraumatic conditions, and it can have serious longterm consequences when unrecognized or untreated. Nontraumatic causes of ACS, such as those associated with cases of prolonged immobilization and/or extremity compression, can be easily overlooked, and several cases of ACS occurring with prolonged surgical positioning can be found in the literature. We present the case of a 19-year-old Army paratrooper who developed acute anterior and lateral compartment syndrome of the lower extremity after being immobilized in an aircraft for hours with several hundred pounds of equipment compressing his lower extremities. To our knowledge, this is the first documented case of ACS occurring as a result of prejump conditions. It demonstrates a potentially serious complication that could result in medical separation and/or permanent disability of the service member. ACS of the extremity should be considered in any Soldier who is required to bear heavy loads, is immobilized for several hours at a time, and complains of symptoms such as extremity pain, numbness, and weakness. 2016.

    Heroin use has been increasing in the United States with the rate of heroin overdose nearly quadrupling in the last 10 years. Heroin overdose can occasionally lead to compartment syndrome (CS) because of extended periods of immobility and pressure tissue injury. Heroin-related compartment syndrome (HRCS) has previously been described, but has been limited to isolated case reports. We sought to examine our experience with HRCS in the climate of rising rates of heroin use among the general population. Medical records of all patients undergoing operative decompression for a CS at our academic medical center over a six-year period (2010-2015) were examined. Patient demographics, operation performed, and etiology were recorded. Cases of HRCS were identified, and clinical outcomes examined. A total of 213 patients undergoing fasciotomy were identified. Twenty-two of these patients had HRCS. Heroin was the second most common etiology of CS after trauma. Only one case of HRCS presented during the first three years of the study period, with the remaining 95 per cent of cases occurring within the last three years. The most common single location for HRCSs was gluteal (31.8%); 36 per cent of HRCS patients needed dialysis and 27 per cent suffered complications such as tissue loss. The incidence of HRCS has increased dramatically over the past several years and is now the second most common etiology for CS in our patient population. Patients with HRCS may present with severe manifestations of CS and different body areas affected.

    Severe acute pancreatitis may be complicated by intra-abdominal hypertension (IAH), abdominal compartment syndrome (ACS), and intestinal ischemia. The aim of this retrospective study is to describe the incidence, treatment, and outcome of patients with severe acute pancreatitis and ACS, in particular the occurrence of intestinal ischemia. The medical records of all patients admitted with severe acute pancreatitis admitted to the ICU of a tertiary referral center were reviewed. The criteria proposed by the World Society of the Abdominal Compartment Syndrome (WSACS) were used to determine whether patients had IAH or ACS. Fifty-nine patients with severe acute pancreatitis were identified. Intra-abdominal pressure (IAP) measurements were performed in 29 patients (49.2 %). IAH was present in all patients (29/29). ACS developed in 13/29 (44.8 %) patients. Ten patients with ACS underwent decompressive laparotomy. A large proportion of patients with ACS had intra-abdominal ischemia upon laparotomy: 8/13 (61.5 %). Mortality was high in both the ACS group and the IAH group. This study confirms that ACS is common in severe acute pancreatitis. Intra-abdominal ischemia occurs in a large proportion of patients with ACS. Swift surgical intervention may be indicated when conservative measures fail in patients with ACS. National and international guidelines need to be updated so that routine IAP measurements become standard of care for patients with severe acute pancreatitis in the ICU.

    Serum levels of maternal lipids rise physiologically in normal pregnancy, and women with underlying hypertriglyceridemia may experience dramatic elevations which place them at risk for pancreatitis. We describe the case of a woman with severe familial hypertriglyceridemia and prior pancreatitis who discontinued her lipid-lowering therapy early in pregnancy. She promptly developed severe abdominal pain and was hospitalized with acute pancreatitis during the late first trimester. Despite aggressive medical treatment and critical care monitoring, she developed abdominal compartment syndrome (ACS) with associated acute renal failure, which progressed to cardiorespiratory failure and was ultimately fatal. ACS is an alarming complication of acute pancreatitis that has been poorly studied in pregnancy. Copyright © 2017 Society of Obstetricians and Gynaecologists of Canada. Published by Elsevier Inc.

    Full Text Available Objective. To describe a profoundly immunocompromised (panleukopenia child with septic shock who developed abdominal compartment syndrome (ACS and was successfully treated with surgical decompression. Design. Individual case report. Setting. Pediatric intensive care unit of a tertiary children's hospital. Patient. A 32-month-old male with Fanconi anemia who underwent bone marrow transplantation (BMT 5 days prior to developing septic shock secondary to Streptococcus viridans and Escherichia coli ACS developed after massive fluid resuscitation, leading to cardiopulmonary instability. Interventions. Emergent surgical bedside laparotomy and silo placement. Measurements and Main Results. The patient's cardiopulmonary status stabilized after decompressive laparotomy. The abdomen was closed and the patient survived to hospital discharge without cardiac, respiratory, or renal dysfunction. Conclusions. The use of laparotomy and silo placement in an unengrafted BMT patient with ACS and septic shock did not result in additional complications. Surgical intervention for ACS is a reasonable option for high risk, profoundly immunocompromised patients.

    In patients with reduced mobility, specialised pressure-relieving supports (mattresses, beds and cushions) are widely used to reduce or relieve the interface pressure between the skin and support surfaces to prevent incidence of pressure ulcers (PUs). The primary objective of these two observational studies was to assess the incidence of PUs in patients at high risk of PUs, seated in a wheelchair using a single- or multi-compartment air cushion. The level of patient satisfaction with the comfort and the views of the care team that used the air cushions were considered as secondary objectives. The PRESCAROH project was two prospective observational studies conducted in patients free of PUs at baseline and at high risk of PUs (Braden score ≤13 or ≤16 for people with spinal cord injury). Patients had to spend more than eight hours a day in a wheelchair and use either a single-compartment air cushion (patient without asymmetry of support) for the first study or a multi-compartment air cushion (patient with asymmetry of support) for the second study. The primary end point was the percentage of patients in whom a PU (sacrum and/or ischium) developed over a 35-day period. The analysis was performed on the full-analysis set (FAS) of patients included with at least a second assessment. We recruited 152 patients, 78 seated on a single-compartment air cushion (SiCAC group) and 74 on a multi-compartment air cushion (MuCAC group), in the two independent studies. All patients were included in the FAS (n=152). Most patients had spinal cord injuries. The average time spent sitting was 10.2 (standard deviation (SD): 2.3) hours a day in the SiCAC group and 9.1 (SD: 1.9) hours a day in the MuCAC group. In the SiCAC group, 6.4% (5/78) of patients dropped out of the study (one patient because of pulmonary infection and four patients for cushion installation problems). In the MuCAC group, 8.1% (6/74) of patients dropped out of the study (three patients because of adverse events not

    Full Text Available Background: Snakebite is a health issue specific to some parts of the world, especially in the tropical area, where it produces many victims. The main clinical damage caused by snake bite involves hemotoxic, neurotoxic and myotoxic reactions. It is also established that the importance of systemic impairment varies according to individual factors and are related to organ dysfunction, shock or hypotension. We report the case of a young woman suffering from snakebite who developed deep vein thrombosis and compartment syndrome. Case Report: We present the case of a 32-year-old Romanian woman who was injured by her own Crotalinae snake (also known as pit viper or rattlesnake on her left forearm. When admitted to our Emergency Department, she was conscious with a Glasgow coma scale of 12/15, somnolent, febrile, suffering of headache, tachypnea; the marks of the snakebite were located in the distal part of the anterior left forearm; she had pain and bleeding at the bite site and swelling of the left upper limb with lymphangitis up to the axilla. She experienced fasciotomy-requiring compartment syndrome of the upper limb and required unfractionated heparin and closed monitored using activated partial thromboplastin time evolution due micro-thrombosis in the brachial vein. Local improvement was achieved in the next 4 days with progressive diminish of local tenderness and swelling. Conclusion: Limb deep vein thrombosis might be induced by snakebite, despite pro-hemorrhagic general condition induced by the envenomation. High index of clinical suspicion is needed for early diagnosis and timely management which can improve survival of these patients

    Chronic exertional compartment syndrome (CECS) is a common cause of exertional leg pain. It is commonly treated with a surgical fasciotomy, which has a surgical complication rate of up to 16% and takes approximately 6-12 weeks to return to preprocedure activity levels. Therefore, the development of a less invasive, effective outpatient intervention to treat CECS is desirable. To describe and validate an ultrasound-guided (USG) fasciotomy technique for the anterior and lateral compartments of the lower limb in an unembalmed cadaveric model. Prospective, cadaveric laboratory investigation. Academic institution procedural skills laboratory. Ten unembalmed cadaveric knee-ankle-foot specimens from 1 female (2 specimens) and 7 male donors aged 62-91 years (mean 78.6 years) with body mass indices of 18.9-35.3 kg/m 2 (mean 27.1 kg/m 2 ). Two experienced operators each performed USG anterior and lateral compartment fasciotomies on 5 unembalmed cadaveric legs. A third physician subsequently dissected the legs to assess the continuity of the fasciotomies and to identify any neurovascular damage related to the procedures. Fasciotomy length (in centimeters) and classification by completeness (achieved target length or did not achieve target length) and continuity (continuous or discontinuous) based on predetermined criteria. Muscles, retinaculae, and neurovascular structures were assessed for damage. No neurovascular injuries occurred in any of the 20 USG fasciotomies. The average fasciotomy length was 22.5 cm. All 20 of the fasciotomies achieved the target length. A continuous cephalocaudal fasciotomy was accomplished in 13 of 20 fasciotomies. When a fasciotomy was not continuous, the average length and number of intact fascial bands was 1.52 cm and 2.3, respectively. USG fasciotomy of the anterior and lateral leg compartments can be safely performed in a cadaveric model and can achieve a fasciotomy length comparable to surgical fasciotomy. Most procedures successfully

    2018-01-01

    Full Text Available We report the case of a 30-year-old Polynesian male with a severe gout flare of multiple joints and simultaneous acute compartment syndrome (ACS of his right forearm and hand without trauma or other typical causes. He had a long history of gout flares, but none were known to be associated with compartment syndrome. He also had concurrent infections in his right elbow joint and olecranon bursa. A few days prior to this episode of ACS, high pain and swelling occurred in his right upper extremity after a minimal workout with light weights. A similar episode occurred seven months prior and was attributed to a gout flare. Unlike past flares that resolved with colchicine and/or anti-inflammatory medications, his current upper extremity pain/swelling worsened and became severe. Hand and forearm fasciotomies were performed. Workup included general medicine, rheumatology and infectious disease consultations, myriad blood tests, and imaging studies including Doppler ultrasound and CT angiography. Additional clinical history suggested that he had previously unrecognized recurrent exertional compartment syndrome that led to the episode of ACS reported here. Chronic exertional compartment syndrome (CECS presents a difficult diagnosis when presented with multiple symptoms concurrently. This case provides an example of one such diagnosis.

    In this article, we present a 7-year-old boy with Schoenlein-Henoch purpura (HSP) presented with compartment syndrome and factor XIII deficiency and treated with recombinant factor VIIa and fasciotomy. Treatment decisions for patients with HSP presenting with compartment syndrome should be made on a case-by-case basis. Factor XIII deficiency should be in mind in these patients. The use of recombinant factor VIIa might be effective and well tolerated for treating hemorrhage in patients with HSP and compartment syndrome. Surgical treatment should be preferred in patients with compartment syndrome. However, in patients who have a coagulation defect, the first priority is to correct the clotting deficiency. The use of recombinant factor VIIa is a treatment option for children who develop compartment syndrome due to a coagulation defect.

    Abdominal compartment syndrome (ACS) in children is an infrequently reported, rapidly progressive, and often lethal condition underappreciated in the pediatric population. This underrecognition can result in a critical delay in diagnosis causing increased morbidity and mortality. This study examines the clinical course of patients treated for ACS at our institution. A review of children requiring an emergency laparotomy (n = 264) identified 26 patients with a diagnosis of ACS. ACS was defined as sustained intraabdominal hypertension (bladder pressure >12 mm Hg) that was associated with new onset organ dysfunction or failure. Patients ranged in age from 3 months to 17 years old and were cared for in the pediatric intensive care unit (PICU). Twenty-seven percent (n = 7) were transferred from referring hospitals, 50% (n = 13) were admitted directly from the emergency department, and 23% (n = 6) were inpatients before being transferred to PICU. Admission diagnoses included infectious enterocolitis (n = 12), postsurgical procedure (n = 10), and others (n = 4). Patients progressed to ACS rapidly, with most requiring decompressive laparotomy within 8 hours of PICU admission (range, syndrome in children carries a high mortality and may be a consequence of common childhood diseases such as enterocolitis. The diagnosis of ACS and the potential need for emergent decompressive laparotomy may be infrequently discussed in the pediatric literature. Increased awareness of ACS may promote earlier diagnosis, treatment, and possibly improve outcomes. Copyright 2010 Elsevier Inc. All rights reserved.

    To evaluate the efficacy of using the Orthopaedic Trauma Association (OTA/AO) classification for both bone forearm fractures in predicting compartment syndrome. Retrospective cohort. Level 1 Academic Trauma Center. One hundred fifty-one patients 18 years of age and older, with both bone forearm fractures diagnosed from 2001 to 2016 were categorized based on the OTA/AO classification. Patients with both bone fractures caused by gunshot wounds were excluded. The endpoint for our study was whether forearm fasciotomies were performed based on the presence of compartment syndrome. Of a total of 151 both bone forearm fractures, 15% underwent fasciotomy. Six of 80 (7.5%) grouped 22-A3, 8 of 44 (18%) grouped 22-B3, and 9 of 27 (33%) grouped 22-C underwent fasciotomies for compartment syndrome (P = 0.004). The relative risks of developing compartment syndrome for group 22-B3 versus 22-A3 was 2.42 (P = 0.08), 22-C versus 22-B3 was 1.83 (P = 0.15), and 22-C versus 22-A3 was 4.44 (P = 0.002). There is a significant correlation between the OTA/AO classification and the need for fasciotomies, with group C fractures representing the highest risk. Clinicians can use this information to have a higher index of suspicion for compartment syndrome based on OTA/AO classification to help minimize the risk of a missed diagnosis. Prognostic Level III.

    BACKGROUND Prader-Willi syndrome (PWS) is a genetic disorder characterized by initial muscular hypotonia and feeding difficulties, and later an insatiable appetite, hyperphagia and obesity along with mild to moderate intellectual impairment. Affected individuals' food-seeking behavior and suspected delayed gastric emptying can lead to gastric dilatation with subsequent necrosis and perforation. CASE REPORT We present the case of a 5-year-old boy diagnosed with Prader-Willi syndrome at neonatal age due to muscular hypotonia, who started growth hormone therapy at 20 months. He presented with two episodes of a rapidly progressing gastric dilatation that led to abdominal hypertension and secondary shock at the age of 2 and 5. No large amount of food was eaten before any of the episodes, and he had abdominal pain and vomiting on both occasions. On arrival at the emergency room, a nasogastric tube was placed and aspiration of food material was performed. Abdominal X-ray and CT scan revealed massive gastric dilatation. He was admitted at the Pediatric Intensive Care Unit and after a variable period of fasting, tolerated oral intake and could be discharged. CONCLUSIONS Gastric dilatation due to gastroparesis in PWS is a rare complication. However, it is a life-threatening situation and physicians should therefore maintain a high level of suspicion for gastric dilatation when patients present with warning symptoms such as abdominal pain or discomfort and vomiting.

  16. Interventional Treatment of Abdominal Compartment Syndrome during Severe Acute Pancreatitis: Current Status and Historical Perspective

    2016-01-01

    Full Text Available Abdominal compartment syndrome (ACS in patients with severe acute pancreatitis (SAP is a marker of severe disease. It occurs as combination of inflammation of retroperitoneum, visceral edema, ascites, acute peripancreatic fluid collections, paralytic ileus, and aggressive fluid resuscitation. The frequency of ACS in SAP may be rising due to more aggressive fluid resuscitation, a trend towards conservative treatment, and attempts to use a minimally invasive approach. There remains uncertainty about the most appropriate surgical technique for the treatment of ACS in SAP. Some unresolved questions remain including medical treatment, indications, timing, and interventional techniques. This review will focus on interventional treatment of this serious condition. First line therapy is conservative treatment aiming to decrease IAP and to restore organ dysfunction. If nonoperative measures are not effective, early abdominal decompression is mandatory. Midline laparostomy seems to be method of choice. Since it carries significant morbidity we need randomized studies to establish firm advantages over other described techniques. After ACS resolves efforts should be made to achieve early primary fascia closure. Additional data are necessary to resolve uncertainties regarding ideal timing and indication for operative treatment.

    Full Text Available Background. Abdominal compartment syndrome (ACS is a rapid increase in intra-abdominal pressure associated with multi-organs dysfunction. It is caused mostly by abdominal bleeding und massive volume compensation. Case report. We reported a 76-year-old patient admitted to the hospital with aortic abdominal aneurysm, 13.7 cm in diameter, ruptured in vena cava, which caused intraabdominal hypertension, the liver and kidney dysfunction, as well as circulation, respiration and metabolic disorders. Intraabdominal pressure was measured by bladder manometry. Central venous pressure and systemic arterial pressure were monitored continuously. Clinical signs were thrill and typical abdominal bruit. Aorto-caval fistula was diagnosed by the use of contrast computerized tomography. Caval endoaneurysmatic suture and aortobiiliac bypass with 18 × 9 mm Dacron prothesis were performed. Haemodynamic changes were mostly corrected during the surgery. The complete correction of haemodynamics, liver, kidney, respiration and metabolic changes was established in the next few weeks. Conclusion. The ACS was caused by rupture of abdominal aortic aneurysm in vena cava followed by edema of the abdominal organs, retroperitoneum, abdominal wall and ascites. Caval endoaneurysmatic suture and aortobiiliac bypass with 18 × 9 mm Dacron prothesis solved aortocaval fistula as well as all the organs and metabolic dysfunctions caused by ACS.

    The purpose of this prospective study was to demonstrate the findings of MRI in motocross racers with chronic exertional compartment syndrome (CECS) of the forearm. Racers with proven CECS and without CECS and male individuals not involved in strenuous activities with the forearm were included. Signal intensity (SI) and signal-to-noise ratio (SNR) obtained before and after exercise were compared (D-SNR). Magnetic resonance imaging after exercise showed an increase in SI and SNR in the muscles on T2-WI. The SI increase was obvious in the flexor digitorum superficialis (FDS) and profundus (FDP) in all CECS patients. In addition, a minor SI and SNR increase in the extensor carpi radialis longus (ECRL) was noted. In the non-symptomatic group of motocross racers, there was only a minor increase in SI and the SNR, which was similar in the FDP and ECRL muscles. In the untrained individuals a remarkable increase in the SI and SNR of the FDS/FDP-ECRL was noted. This increased SI and SNR was not present in the majority of non-symptomatic racers. Post-exertional MRI produces significant findings in CECS of the forearm. The motocross racers without post-exertional oedema in the FDP/FDS had no CECS. (orig.)

    Pneumoperitoneum is defined as the existence of extraluminal air in the abdominal cavity. In 80-90% of cases is due to perforation of a hollow organ. However, in 10-15% of cases, it is nonsurgical pneumoperitoneum. The case of a patient undergoing mechanical ventilation, developing abdominal compartment syndrome tension pneumoperitoneum is reported. Female, 75 years old asking for advise due to flu of long term duration. Given her respiratory instability, admission to the Intensive Care Unit is decided. It is then intubated and mechanically ventilated. Chest x-ray revealed a large pneumoperitoneum but no pneumothorax neither mediastinum; and due to the suspicion of viscera perforation with clinical instability secondary to intra-abdominal hypertension box, emergency surgery was decided. When discarded medical history as a cause of pneumoperitoneum, it is considered that ventilation is the most common cause. Benign idiopathic or nonsurgical pneumoperitoneum, can be be treated conservatively if the patient agrees. But if intraabdominal hypertension prevails, it can result in severe respiratory and hemodynamic deterioration, sometimes requiring abdominal decompression to immediately get lower abdominal pressure and thus improve hemodynamic function.

    Full Text Available We report on 4 cases of abdominal compartment syndrome complicated by acute renal failure that were promptly reversed by different abdominal decompression methods. Case 1: A 57-year-old obese woman in the post-operative period after giant incisional hernia correction with an intra-abdominal pressure of 24 mm Hg. She was sedated and curarized, and the intra-abdominal pressure fell to 15 mm Hg. Case 2: A 73-year-old woman with acute inflammatory abdomen was undergoing exploratory laparotomy when a hypertensive pneumoperitoneum was noticed. During the surgery, enhancement of urinary output was observed. Case 3: An 18-year-old man who underwent hepatectomy and developed coagulopathy and hepatic bleeding that required abdominal packing, developed oliguria with a transvesical intra-abdominal pressure of 22 mm Hg. During reoperation, the compresses were removed with a prompt improvement in urinary flow. Case 4: A 46-year-old man with hepatic cirrhosis was admitted after incisional hernia repair with intra-abdominal pressure of 16 mm Hg. After paracentesis, the intra-abdominal pressure fell to 11 mm Hg.

    Current surgical education relies on simulated educational experiences or didactic sessions to teach low-frequency clinical events such as abdominal compartment syndrome (ACS). The purpose of this pilot study was to evaluate if simulation would improve performance and knowledge retention of ACS better than a didactic lecture. Nineteen general surgery residents were block randomized by postgraduate year level to a didactic or a simulation session. After 3 months, all residents completed a knowledge assessment before participating in an additional simulation. Two independent reviewers assessed resident performance via audio-video recordings. No baseline differences in ACS experience were noted between groups. The observational evaluation demonstrated a significant difference in performance between the didactic and simulation groups: 9.9 vs 12.5, P = .037 (effect size = 1.15). Knowledge retention was equivalent between groups. This pilot study suggests that simulation-based education may be more effective for teaching the basic concepts of ACS.

    Compartment syndromes, caused by elevated intramuscular pressure (IMP) and resulting from trauma or chronic overuse, frequently require invasive IMP monitoring for accurate diagnosis. Our objective is to test a non-invasive ultrasound technique for estimating IMP based on fascial displacement waveforms from arterial blood pressure pulses. In this study, IMP was increased in the legs of 23 healthy adult subjects up to 80 mmHg using two blood pressure cuffs covering the region from the knee to the ankle. Receiver operator characteristic (ROC) curves and recursive partitioning were used to determine the sensitivity and specificity of diagnosing elevated IMP using fascial displacement. For one ROC curve, in which several ultrasonic measurement parameters were used along with subject body mass index and blood pressure, the sensitivity and specificity for diagnosing normal IMP (below 30 mmHg) from elevated IMP (30 mmHg and up) was 0.61 and 0.94 respectively. Recursive partitioning, in which IMP was divided into three ranges (normal = 50 mmHg), resulted in improved diagnostic sensitivity (0.77) with almost no change in specificity (0.93). PMID:18979529

    A 6-year-old Holstein cow was examined because of chronic lameness and swelling near the stifle joint of the left pelvic limb. A mass was palpated in the soft tissues lateral to the proximal aspect of the left tibia. Multiple attempts to obtain a biopsy specimen of the mass resulted in acute compartment syndrome of the femoral compartment (tensor fasciae latae and biceps femoris muscles) and lateral tibial compartment (cranial tibial and peroneus tertius muscles) with associated sciatic nerve paralysis. Surgical decompression via tensor fasciae latae and biceps femoris incision resolved the sciatic nerve paralysis. On the fifth day following surgery, the cow began to develop signs of increased respiratory effort. Thoracic radiography revealed a pulmonary metastatic micronodular pattern. The cow was euthanized because its condition deteriorated. Metastatic hemangiosarcoma was confirmed at necropsy, and the primary tumor was the mass that was lateral to the tibia and within the biceps femoris muscle. Hemangiosarcoma should be considered a differential diagnosis for lameness in cattle when no orthopedic cause can be identified. Close patient surveillance is strongly recommended in the event that a vascular tumor is present because catastrophic consequences are possible. To our knowledge, this is the first report of acute compartment syndrome in a pelvic limb of a bovine patient and the only report of hemangiosarcoma in the skeletal muscle of cattle.

    Full Text Available Context: Abdominal compartment syndrome (ACS is associated with high morbidity and mortality among trauma patients. Several clinical and laboratory findings have been suggested as markers for ACS, and these may point to different types of ACS and complications. Aims: This study aims to identify the strength of association of clinical and laboratory variables with specific adverse outcomes in trauma patients with ACS. Settings and Design: A 5-year retrospective chart review was conducted at three Level I Trauma Centers in the City of Chicago, IL, USA. Subjects and Methods:A complete set of demographic, pre-, intra- and post-operative variables were collected from 28 patient charts. Statistical Analysis:Pearson's correlation coefficient was used to determine the strength of association between 29 studied variables and eight end outcomes. Results: Thirty-day mortality was associated strongly with the finding of an initial intra-abdominal pressure >20 mmHg and moderately with blunt injury mechanism. A lactic acid >5 mmol/L on admission was moderately associated with increased blood transfusion requirements and with acute renal failure during the hospitalization. Developing ACS within 48 h of admission was moderately associated with increased length of stay in the Intensive Care Unit (ICU, more ventilator days, and longer hospital stay. Initial operative intervention lasting more than 2 h was moderately associated with risk of developing multi-organ failure. Hemoglobin level 7 days were moderately associated with a disposition to long-term support facility. Conclusions: Clinical and lab variables can predict specific adverse outcomes in trauma patients with ACS. These findings may be used to guide patient management, improve resource utilization, and build capacity within trauma centers.

  6. Compartment syndrome of thigh and lower leg with disruption of the popliteal vascular bundle after being run over by a 25-ton truck

    Full Text Available 【Abstract】Compartment syndrome of the thigh is a rare condition, potentially resulting in devastating functional outcome. Increasing intracompartmental pressure which suppresses microcirculation and capillary perfusion may lead to cellular anoxia and muscle ischemia. The muscle compartments in the thigh have a more compliant fascia and blend anatomically into the open compartments of the pelvis, thus compensating higher volumes than the compartments in the lower leg. We present a previously unreported case in which the limb of a 36-year-old man was run over by a 25-ton truck. He presented with a sensomotor deficit in his left lower leg with full paralysis of the shank muscles and absence of all foot pulses. CT scan showed a huge haematoma in the thigh with active bleeding out of the popliteal artery into the haematoma which has already expanded into the muscle compartments of the lower leg. The limb had a disastrous compartment syndrome of the thigh and lower leg with disruption of the popliteal neurovascular bundle; however, no bones in the limb were fractured. A complete fasciotomy of all the lower limb muscle compartments was immediately performed. The artery was reconstructed with interposition of the smaller saphenous vein, which was already interrupted through the initial trauma.

    A 38-year-old woman underwent a 4-hour operation in the prone position for a laminectomy at C4-7 and posterior cervical decompressive fusion at C7-T1 under general anesthesia. After undraping at the end of surgery, considerable swelling with many blisters of the left forearm and hand was observed. The chest roll at the left side had moved cephalad into the axilla and compressed the axillary structures. An emergency fasciotomy to decompress the compartments of the forearm and dorsal surface of the hand was performed. In the post anesthesia care unit, the radial pulse of the left hand was palpable and the level of oxygen saturation was normal. Forearm and hand edema subsided gradually over several days and the patient was discharged with full function of her left arm. This compartment syndrome suggests careful attention should be paid to the position of the chest roll when the prone position is established for a long duration.

    Lesions of the intra-abdominal organs and vessels caused by trocars and Verres needles are rare but serious complications during laparoscopic surgery. We report an unusual case of left common iliac artery and inferior vena cava injury during laparoscopy. This lesion was followed by a bilateral postischemic compartment syndrome of the lower extremities. The patient sustained massive rhabdomyolysis, renal failure, peroneal nerve palsy, and functional loss of the lower extremities. Postischemic tissue swelling should be recognized as early as possible because it is a life-threatening condition that necessitates immediate treatment.

    The invention of computer and advancement in information technology has revolutionized and benefited the society but at the same time has caused symptoms related to its usage such as ocular sprain, irritation, redness, dryness, blurred vision and double vision. This cluster of symptoms is known as computer vision syndrome which is characterized by the visual symptoms which result from interaction with computer display or its environment. Three major mechanisms that lead to computer vision syndrome are extraocular mechanism, accommodative mechanism and ocular surface mechanism. The visual effects of the computer such as brightness, resolution, glare and quality all are known factors that contribute to computer vision syndrome. Prevention is the most important strategy in managing computer vision syndrome. Modification in the ergonomics of the working environment, patient education and proper eye care are crucial in managing computer vision syndrome.

    2009-01-01

    Treacher Collins syndrome (TCS) is a rare congenital disorder of craniofacial development that arises as the result of mutations in the TCOF1 gene, which encodes a nucleolar phosphoprotein known as Treacle. Individuals diagnosed with TCS frequently undergo multiple reconstructive surgeries, which are rarely fully corrective. Identifying potential avenues for rescue and/or repair of TCS depends on a profound appreciation of the etiology and pathogenesis of the syndrome. Recent research using animal models has not only determined the cellular basis of TCS but also, more importantly, unveiled a successful avenue for therapeutic intervention and prevention of the craniofacial anomalies observed in TCS.

    2016-12-01

    Chronic Exertional Compartment Syndrome (CECS) causes significant exercise related pain secondary to increased intra-compartmental pressure (ICP) in the lower extremities. CECS is most often treated with surgery with minimal information available on non-operative approaches to care. This case report presents a case of CECS successfully managed with physical therapy. Case report. A 34-year-old competitive triathlete experienced bilateral anterior and posterior lower leg pain measured with a numerical pain rating scale of 7/10 at two miles of running. Pain decreased to resting levels of 4/10 two hours post exercise. The patient was diagnosed with bilateral CECS with left lower extremity ICP at rest measured at 36 mmHg (deep posterior), 36-38 mmHg (superficial posterior), and 25 mmHg (anterior). Surgery was recommended. The patient chose non-operative care and was treated with physical therapy using the Functional Manual Therapy approach aimed at addressing myofascial restrictions, neuromuscular function and motor control deficits throughout the lower quadrant for 23 visits over 3.5 months. At discharge the patient had returned to running pain free and training for an Olympic distance triathlon. The Lower Extremity Functional Scale improved from 62 to 80. The patient reported minimal post exercise tightness in bilateral lower extremities. Left lower extremity compartment pressure measurements at rest were in normal ranges measuring at 11 mmHg (deep posterior), 8 mmHg (superficial posterior), 19 mmHg (anterior), and 10 mmHg (lateral). Three-years post intervention the patient remained pain free with a Global Rating of Change of 6. This case report describes the successful treatment of a triathlete with Functional Manual Therapy resulting in a return to competitive sports without pain. Level 4.

    Neuromuscular control of the scapular muscles is important in the etiology of shoulder pain. Electromyographical (EMG) biofeedback in healthy people has been shown to support a selective activation of the lower compartment of the trapezius muscle, specifically. The aim of the present paper...... was to investigate whether patients with Subacromial Impingement Syndrome (SIS) were able to selectively activate the individual compartments within the trapezius muscle, with and without EMG biofeedback to the same extent as healthy controls (No-SIS). Fifteen SIS and 15 No-SIS participated in the study. Sessions...... with and without visual biofeedback were conducted. Surface EMG was recorded from four compartments of the trapezius muscle. Selective activation was defined as activation above 12% with other muscle parts below 1.5% or activation ratio at or above 95% of the total activation. Without biofeedback significantly...

    Full Text Available A 22-year-old male came to casualty on 5 th May 2012 after a fall from motorcycle. He complained of excruciating pain and swelling over right knee. There was an open wound of 7 × 2 cm over supra-patellar region and diffuse swelling over knee joint with severe tenderness over proximal aspect of right tibia. X-ray showed intra-articular fracture of proximal tibia extending to diaphysis classified as type 6 by Schatzker classification for proximal tibia, with fibula shaft transverse fracture. The skin over the fracture was contused. Debridement with primary wound closure was done in emergency. Skeletal traction was applied through a lower tibial Steinman pin. Patient was operated after 15 days when wound healed and swelling subsided. Locking plate was applied on medial aspect using Minimally invasive percutaneous plate osteosysthesis (MIPPO technique. Post-operatively over 4 hours patient developed severe pain and swelling in operated leg which mimicked compartment syndrome. Suture removal was done immediately in the ward from the distal aspect, which relieved the symptoms but lead to exposure of the plate. A rotational flap was done to cover the plate in coordination with a plastic surgeon on the next day.

    Idiopathic nephrotic syndrome (INS) is a kidney disease characterized by massive proteinuria. Protein loss leads to decreased oncotic pressure shifting the fluids into the interstitial space causing edema, complications such as infections and thromboembolism occur. We report a 7-year-old, diagnosed with NS presenting with a relapse. He developed ascites and scrotal edema followed by severe scrotal pain and redness, progressing rapidly to ecchymosis in the inguinal areas not in continuity with the scrotum. Ultrasound with color Doppler was inconclusive, scrotal exploration was done along with skin incision in the inguinal areas and scrotum, which appeared to relieve the condition rapidly.

    To analyze the rate of postoperative infection and nonunion after tibial fractures in patients treated for acute compartment syndrome (ACS) using (1) single-incision versus (2) dual-incision fasciotomy technique. Retrospective. Level I trauma center. Review of all adult tibial fractures operatively treated (n = 2756) over a 12-year period identified 175 patients with concurrent ACS requiring fasciotomy. Of 60 patients treated with intramedullary nails, 36 patients had single-incision fasciotomy and 24 had dual-incision fasciotomy. Of 81 patients treated with plate fixation, 59 patients had single-incision fasciotomy and 22 had dual-incision fasciotomy. Tibial fixation with fasciotomy for ACS. Occurrence of postoperative infection and nonunion. Both fasciotomy groups were similar across recorded patient and treatment characteristics. Need for skin graft was similar between fasciotomy groups. For patients treated with intramedullary nail (n = 60), 1 infection (2.8%) occurred in single-incision group versus 2 (8.3%) in dual-incision group (P = 0.558). Seven nonunions (19.4%) occurred in single-incision group versus 3 (12.5%) in dual-incision group (P = 0.726). For plate fixation patients (n = 81), 15 infections (25.4%) occurred with single-incision fasciotomy versus 5 infections (22.7%) with dual-incision fasciotomy (P = 1.000). Seven nonunions (11.9%) occurred with single-incision group versus 4 nonunions (18.2%) with dual-incision group (P = 0.479). This is the first study to compare a single-incision fasciotomy technique to a dual-incision technique in the setting of tibial fractures with ACS, with similar infection and nonunion rates with either technique. The choice of fasciotomy technique can be based on surgeon experience or patient condition as opposed to a suspected elevated infection or nonunion risk with either technique. Therapeutic Level III.

    Acute compartment syndrome (ACS) is a clinical condition with potentially dramatic consequences, therefore, it is important to recognise and treat it early. Good management of ACS minimises or avoids the sequelae associated with a late diagnosis, and may also reduce the risk of malpractice claims. The aim of this article was to evaluate different errors ascribed to the surgeon and to identify how the damage was evaluated. A total of 66 completed and closed ACS cases were selected. The following were analysed for each case: clinical management before and after diagnosis of ACS, imputed errors, professional fault, damage evaluation and quantification. Particular attention was paid to distinguishing between impairment because of primary injury and iatrogenic impairment. Statistical analyses were performed using Fisher's exact test and Pearson's correlation. The most common presenting symptom was pain. Delay in the diagnosis, and hence delay in decompression, was common in the study. A total of 48 out of 66 cases resolved with the verdict of iatrogenic damage, which varied from 12% to 75% of global capability of the person. A total of $394,780 out of $574,680 (average payment) derived from a medical error. ACS is a clinical emergency that requires continuous clinical surveillance from both medical and nursing staff. The related damage should be evaluated in two parts: damage deriving from the trauma, so that it is considered inevitable and independent from the surgeon's conduct, and damage deriving from a surgeon's error, which is eligible for an indemnity payment.

  6. Surfactant disaturated-phosphatidylcholine kinetics in acute respiratory distress syndrome by stable isotopes and a two compartment model

    Directory of Open Access Journals (Sweden)

    Cogo Paola E

    2007-02-01

    Full Text Available Abstract Background In patients with acute respiratory distress syndrome (ARDS, it is well known that only part of the lungs is aerated and surfactant function is impaired, but the extent of lung damage and changes in surfactant turnover remain unclear. The objective of the study was to evaluate surfactant disaturated-phosphatidylcholine turnover in patients with ARDS using stable isotopes. Methods We studied 12 patients with ARDS and 7 subjects with normal lungs. After the tracheal instillation of a trace dose of 13C-dipalmitoyl-phosphatidylcholine, we measured the 13C enrichment over time of palmitate residues of disaturated-phosphatidylcholine isolated from tracheal aspirates. Data were interpreted using a model with two compartments, alveoli and lung tissue, and kinetic parameters were derived assuming that, in controls, alveolar macrophages may degrade between 5 and 50% of disaturated-phosphatidylcholine, the rest being lost from tissue. In ARDS we assumed that 5–100% of disaturated-phosphatidylcholine is degraded in the alveolar space, due to release of hydrolytic enzymes. Some of the kinetic parameters were uniquely determined, while others were identified as lower and upper bounds. Results In ARDS, the alveolar pool of disaturated-phosphatidylcholine was significantly lower than in controls (0.16 ± 0.04 vs. 1.31 ± 0.40 mg/kg, p de novo synthesis of disaturated-phosphatidylcholine were also significantly lower, while mean resident time in lung tissue was significantly higher in ARDS than in controls. Recycling was 16.2 ± 3.5 in ARDS and 31.9 ± 7.3 in controls (p = 0.08. Conclusion In ARDS the alveolar pool of surfactant is reduced and disaturated-phosphatidylcholine turnover is altered.

  7. Non-invasive neurosensory testing used to diagnose and confirm successful surgical management of lower extremity deep distal posterior compartment syndrome

    Directory of Open Access Journals (Sweden)

    Guyton Gregory P

    2009-05-01

    Full Text Available Abstract Background Chronic exertional compartment syndrome (CECS is characterized by elevated pressures within a closed space of an extremity muscular compartment, causing pain and/or disability by impairing the neuromuscular function of the involved compartment. The diagnosis of CECS is primarily made on careful history and physical exam. The gold standard test to confirm the diagnosis of CECS is invasive intra-compartmental pressure measurements. Sensory nerve function is often diminished during symptomatic periods of CECS. Sensory nerve function can be documented with the use of non-painful, non-invasive neurosensory testing. Methods Non-painful neurosensory testing of the myelinated large sensory nerve fibers of the lower extremity were obtained with the Pressure Specified Sensory Device™ in a 25 year old male with history and invasive compartment pressures consistent with CECS both before and after running on a tread mill. After the patient's first operation to release the deep distal posterior compartment, the patient failed to improve. Repeat sensory testing revealed continued change in his function with exercise. He was returned to the operating room where a repeat procedure revealed that the deep posterior compartment was not completely released due to an unusual anatomic variant, and therefore complete release was accomplished. Results The patient's symptoms numbness in the plantar foot and pain in the distal calf improved after this procedure and his repeat sensory testing performed before and after running on the treadmill documented this improvement. Conclusion This case report illustrates the principal that non-invasive neurosensory testing can detect reversible changes in sensory nerve function after a provocative test and may be a helpful non-invasive technique to managing difficult cases of persistent lower extremity symptoms after failed decompressive fasciotomies for CECS. It can easily be performed before and after

    To determine the correlation between the OTA/AO classification of tibia fractures and the development of acute compartment syndrome (ACS). Retrospective review of prospectively collected database. Single Level 1 academic trauma center. All patients with a tibia fracture from 2006 to 2016 were reviewed for this study. Three thousand six hundred six fractures were initially identified. Skeletally mature patients with plate or intramedullary fixation managed from initial injury through definitive fixation at our institution were included, leaving 2885 fractures in 2778 patients. After database and chart review, univariate analyses were conducted using independent t tests for continuous data and χ tests of independence for categorical data. A simultaneous multivariate binary logistic regression was developed to identify variables significantly associated with ACS. ACS occurred in 136 limbs (4.7%). The average age was 36.2 years versus 43.3 years in those without (P AO 43 injuries were at least 4.0 times less likely to foster ACS versus OTA/AO 41 or 42 injuries (P AO 41-C injuries were 5.5 times more likely to advance to ACS compared with OTA/AO 41-A (P = 0.03). There was a significantly higher rate of ACS in OTA/AO 42-B (P = 0.005) and OTA/AO 42-C (P = 0.002) fractures when compared with OTA/AO 42-A fractures. In the distal segment, fracture type did not predict the risk of ACS (P > 0.15). Group 1 fractures had a lower rate of ACS compared with group 2 (P = 0.03) and group 3 (P = 0.003) fractures in the middle segment only. Bilateral tibia fractures had a 2.7 times lower rate of ACS (P = 0.04). Open injury, multiple segment injury, fixation type, and concurrent pelvic or femoral fractures did not predict ACS. In this large cohort of tibia fractures, we found that the age, sex, and OTA/AO classification were highly predictive for the development of ACS. Prognostic Level III.

  12. Prenatal treatment prevents learning deficit in Down syndrome model.

    Directory of Open Access Journals (Sweden)

    Maddalena Incerti

    Full Text Available Down syndrome is the most common genetic cause of mental retardation. Active fragments of neurotrophic factors release by astrocyte under the stimulation of vasoactive intestinal peptide, NAPVSIPQ (NAP and SALLRSIPA (SAL respectively, have shown therapeutic potential for developmental delay and learning deficits. Previous work demonstrated that NAP+SAL prevent developmental delay and glial deficit in Ts65Dn that is a well-characterized mouse model for Down syndrome. The objective of this study is to evaluate if prenatal treatment with these peptides prevents the learning deficit in the Ts65Dn mice. Pregnant Ts65Dn female and control pregnant females were randomly treated (intraperitoneal injection on pregnancy days 8 through 12 with saline (placebo or peptides (NAP 20 µg +SAL 20 µg daily. Learning was assessed in the offspring (8-10 months using the Morris Watermaze, which measures the latency to find the hidden platform (decrease in latency denotes learning. The investigators were blinded to the prenatal treatment and genotype. Pups were genotyped as trisomic (Down syndrome or euploid (control after completion of all tests.two-way ANOVA followed by Neuman-Keuls test for multiple comparisons, P<0.05 was used to denote statistical significance. Trisomic mice who prenatally received placebo (Down syndrome-placebo; n = 11 did not demonstrate learning over the five day period. DS mice that were prenatally exposed to peptides (Down syndrome-peptides; n = 10 learned significantly better than Down syndrome-placebo (p<0.01, and similar to control-placebo (n = 33 and control-peptide (n = 30. In conclusion prenatal treatment with the neuroprotective peptides (NAP+SAL prevented learning deficits in a Down syndrome model. These findings highlight a possibility for the prevention of sequelae in Down syndrome and suggest a potential pregnancy intervention that may improve outcome.

    Full Text Available B lymphocytes are compartmentalized within lymphoid organs. The organization of these compartments depends upon signaling initiated by G-protein linked chemoattractant receptors. To address the importance of the G-proteins Gαi2 and Gαi3 in chemoattractant signaling we created mice lacking both proteins in their B lymphocytes. While bone marrow B cell development and egress is grossly intact; mucosal sites, splenic marginal zones, and lymph nodes essentially lack B cells. There is a partial block in splenic follicular B cell development and a 50-60% reduction in splenic B cells, yet normal numbers of splenic T cells. The absence of Gαi2 and Gαi3 in B cells profoundly disturbs the architecture of lymphoid organs with loss of B cell compartments in the spleen, thymus, lymph nodes, and gastrointestinal tract. This results in a severe disruption of B cell function and a hyper-IgM like syndrome. Beyond the pro-B cell stage, B cells are refractory to chemokine stimulation, and splenic B cells are poorly responsive to antigen receptor engagement. Gαi2 and Gαi3 are therefore critical for B cell chemoattractant receptor signaling and for normal B cell function. These mice provide a worst case scenario of the consequences of losing chemoattractant receptor signaling in B cells.

    Full Text Available A 7-week-old girl presented with disseminated stage 4 neuroblastoma complicated with massive hepatomegaly and signs of liver failure. She underwent wedge liver biopsy and decompressive laparotomy with GORE-TEX® patch placement prior to the administration of chemotherapy. Her fluid losses during chemotherapy were so severe that her GORE-TEX® patch became tense and filled with ascites resulting in abdominal compartment syndrome (ACS. A negative pressure dressing system was applied after opening the patch to assist in the quantification of the fluid losses and to allow decompression. Unfortunately, in spite of favorable histology, the patient failed to adequately respond to chemotherapy resulting in persistent hepatomegaly. Soon after, she developed respiratory, renal insufficiency and disseminated intravascular coagulation, leading to her death 12 days after the initiation of treatment.

    Refeeding syndrome is a life-threatening complication that may occur after initiation of nutritional therapy in malnourished patients, as well as after periods of fasting and hunger. Refeeding syndrome can be effectively prevented and treated if its risk factors and pathophysiology are known. The initial measurement of thiamine level and serum electrolytes, including phosphate and magnesium, their supplementation if necessary, and a slow increase in nutritional intake along with close monitoring of serum electrolytes play an important role. Since refeeding syndrome is not well known and the symptoms can be extremely heterogeneous, this complication is poorly recognized, especially against the background of severe disease and multimorbidity. This overview aims to summarize the current knowledge and increase awareness about refeeding syndrome.

  19. PREVENTION OF THROMBOSES IN ANTIPHOSPHOLIPID SYNDROME

    2009-01-01

    Patients with antiphospholipid (aPL antibodies and venous thromboses need long-term moderate-intensity warfarin therapy. Patients with ischemic strokes without other indications for the use of anticoagulants may be given either warfarin or ASA. In the latter case, there is no need for laboratory control or an individual dose adjustment. The primary prevention of thromboses in the presence of aPL is also performed with ASA. When pregnancy occurs, women with obstetric manifestations of APS may be given small-dose ASA in combination with heparins. To reduce the risk of hemorrhages, warfarin dosage adjustment is initiated with the minimum doses (<5 mg/day. Novel ASA formulations, such as ASA with the unabsorbed antacid magnesium hydroxide, have been developed to prevent gastrointestinal tract complications.

    We report the first case of non-iatrogentic exertional rhabdomyolysis leading to acute compartment syndrome in a patient with McArdle's disease. We describe considerations of concurrent buprenorphine/naloxone therapy during episodes of severe acute pain. Case report. A 50-year-old male with a history of McArdle's disease, taking buprenorphine/naloxone for chronic pain and opioid dependence, presented to the Emergency Department with severe bilateral anterior thigh pain. Over the following 8 hours, he was given a total of 12 mg of intravenous hydromorphone with minimal pain relief. The decision was made to initiate patient-controlled analgesia (PCA) with hydromorphone started at 0.5 mg as needed with a 15-minute lockout. Subsequently, the patient's anterior thighs were found to be extremely tense. His creatine kinase level rose to 198,688 units/L and compartment pressures were greater than 90 mm Hg bilaterally. The patient was taken for emergent bilateral fasciotomies. The hydromorphone PCA was increased to 0.8 mg as needed with a 15-minute lockout and a basal rate of 0.5 mg/h. The patient's reported pain plateaued at 3/10 intensity 2 days after surgery, and he was transitioned to oxycodone and hydrocodone/acetaminophen. He followed up with his pain management physician 2 months later who restarted suboxone and a buphrenorphine transdermal patch. Buprenorphine/naloxone is being prescribed off-label with increasing frequency for pain management in patients with or without a history of opioid abuse. Severe acute pain is more difficult to control with opioid analgesics in patients taking buprenorphine/naloxone, requiring higher than usual doses. If buprenorphine/naloxone is discontinued to better treat acute pain with other opioids, monitoring for overdose must take place for at least 72 hours. Wiley Periodicals, Inc.

    The post-discectomy syndrome (PDS) is a common diagnosis in patients with problems following a disc operation. The different causes of PDS make the establishment of the correct diagnosis and its corresponding efficient treatment difficult. A general overview published in the bibliographical data covering the entity of PDS is rare. The following paper aims to specify PDS according to its aetiology, diagnosis, treatment and prevention. The diagnosis should be made efficiently, so that the patient can receive prompt adequate therapy.

    Frey syndrome is one of the potential sequelae of parotidectomy. Various medical and surgical treatments have been used in an attempt to avoid this embarrassing condition. Recently, interposing barriers between the overlying skin flap and the parotid bed, such as the sternocleidomastoid muscle (SCM) flap, have been used to prevent this condition. The purpose of this study was to evaluate the impact of using this flap on Frey syndrome. A series of 138 patients who underwent subtotal or total parotidectomy from January 1995 to December 2001 were divided into two groups. One group had an SCM flap reconstruction (n = 24), and the other group did not (n = 19). A subjective clinical questionnaire and the objective Minor's starch iodine test were used to evaluate the incidence of this syndrome. The postoperative period varied from 12 to 90 months. The frequency exact test of Fisher and the nonparametric test of Mann-Whitney were applied. The association with the absence of sweating and the presence of the SCM flap was significant (p = 0.0002). There was no association with flushing or pain and the flap. There was a significant association with the starch iodine test and the presence of the flap (p = 0.0016). The only significant association of the epidemiologic and clinical characterization of the patients with a negative or positive Minor's test was between sweating and a positive Minor's test (p = 0.0001). The only significant aspect in the diagnosis of Frey syndrome is gustatory sweating. There is a significant association with a negative Minor's test and the presence of the SCM flap and with sweating and a positive Minor's test. The SCM flap is an efficient method for preventing Frey syndrome following parotidectomy.

  3. The intestinal barrier in irritable bowel syndrome: subtype-specific effects of the systemic compartment in an in vitro model.

    Full Text Available Irritable bowel syndrome (IBS is a disorder with multifactorial pathophysiology. Intestinal barrier may be altered, especially in diarrhea-predominant IBS (IBS-D. Several mediators may contribute to increased intestinal permeability in IBS.We aimed to assess effects of tryptase and LPS on in vitro permeability using a 3-dimensional cell model after basolateral cell exposure. Furthermore, we assessed the extent to which these mediators in IBS plasma play a role in intestinal barrier function.Caco-2 cells were grown in extracellular matrix to develop into polarized spheroids and were exposed to tryptase (10 - 50 mU, LPS (1 - 50 ng/mL and two-fold diluted plasma samples of 7 patients with IBS-D, 7 with constipation-predominant IBS (IBS-C and 7 healthy controls (HC. Barrier function was assessed by the flux of FITC-dextran (FD4 using live cell imaging. Furthermore, plasma tryptase and LPS were determined.Tryptase (20 and 50 mU and LPS (6.25 - 50 ng/mL significantly increased Caco-2 permeability versus control (all P< 0.05. Plasma of IBS-D only showed significantly elevated median tryptase concentrations (7.1 [3.9 - 11.0] vs. 4.2 [2.2 - 7.0] vs. 4.2 [2.5 - 5.9] μg/mL; P<0.05 and LPS concentrations (3.65 [3.00 - 6.10] vs. 3.10 [2.60-3.80] vs. 2.65 [2.40 - 3.40] EU/ml; P< 0.05 vs. IBS-C and HC. Also, plasma of IBS-D increased Caco-2 permeability versus HC (0.14450 ± 0.00472 vs. 0.00021 ± 0.00003; P < 0.001, which was attenuated by selective inhibition of tryptase and LPS (P< 0.05.Basolateral exposure of spheroids to plasma of IBS-D patients resulted in a significantly increased FD4 permeation, which was partially abolished by selective inhibition of tryptase and LPS. These findings point to a role of systemic tryptase and LPS in the epithelial barrier alterations observed in patients with IBS-D.

    This study discusses the anatomy and surgical techniques for the prevention of Frey syndrome. By performing only a partial superficial parotidectomy, we probably preserve the connection between the auriculotemporal nerve and the facial nerve. By suturing the remainder of the parotid gland tissue and the superficial musculoaponeurotic system (SMAS) back to the sternocleidomastoid muscle, an interposition is made. Furthermore, by extending the incision not too far cranially, the auriculotemporal nerve cutaneous branch is spared. We also tried to preserve part of the great auricular nerve (GAN). Descriptive study. One main institute (a tertiary referral centre) and one affiliated secondary centre. Patients operated on for parotid gland tumours in our hospitals during the last 3 years underwent starch-iodine testing after at least 1 year of follow-up. The number of patients developing Frey syndrome. We hypothetically explored the importance of preserving both the auriculotemporal and the great auricular nerve. Eighty-one patients were operated on for a parotid gland tumour. Forty-five (56%) of these patients could be followed up for more than 1 year. Four patients had a positive starch-iodine test. Two of these underwent revision surgery and had symptoms already before our procedure. About half of the patients had a SMAS interposition performed. All four patients with Frey syndrome did not have a SMAS interposition. We advocate our technique in primary benign tumours. Further research to clarify the parasympathetic and sympathetic function of the great auricular nerve and the cutaneous branch of the auriculotemporal nerve is necessary.

    Objective: To assess the efficacy of aspiration of small follicles(ASF) guided by trans-vaginal ultra- sound (TVS) in preventing moderate and severe ovarian hyperstimulation syndrome (OHSS) in women with polycystic ovaries syndrome (PCOS). Methods: ASF was undertaken by trans-vaginally during artificial cycles in 25 women with PCOS who had early signs of OHSS during the early period of the cycle according to the ovaries and follicles detected by TVS. Small follicles(≤ 12 mm in diameter) were aspirated at the early period of gonadotropin therapy according to the follicle testing, three or less excellent follicles were reserve. All the patients were followed up for symptoms and signs of OHSS. Results: None of the patients developed moderate or severe OHSS. Successful intrauterine pregnancy were found in 7 cases (28%). Conclusion: ASF after gonadotropin injections is of significance to prevent moderate and severe OHSS and obtain a higher pregnancy rate in susceptible patients with PCOS during the early period of the cycles. Time of ASF is the main factor to prevent OHSS. TVS may be an important tool in the detection of early period of follicles development. (authors)

    Maternal Phenylketonuria Syndrome (MPKU) can occur in infants born to mothers with PKU with poor metabolic control during pregnancy. Elevated phenylalanine (phe) acts as a teratogen to the developing fetus with consequences including intellectual disability, microcephaly, facial dysmorphism, growth retardation, and congenital heart disease. MPKU can be prevented if metabolic control is achieved by 8-10 weeks gestation. If control is not achieved, there is a significant risk for MPKU. Therefore, in women with poor metabolic control at time of pregnancy, establishing metabolic control quickly is important.Clinically, establishing metabolic control in women with PKU can present challenges. Social issues, psychological issues, and insufficient education about PKU play an important role in a patient's inability to reinstitute this challenging diet. Maintaining phe levels within a range to allow for infant growth, while preventing toxicity, is challenging, particularly for those women who no longer follow the PKU diet. Gastrostomy tube placement is an option to deliver medical formula to women who are unable to restart diet due to severe nausea or palatability issues.Here we discuss two pregnancies in which a gastrostomy tube was placed to achieve metabolic control after other measures failed to reduce phe concentrations into the recommended range. For these two pregnancies, placement of the gastrostomy tube led to improvement in phe levels with normal infant outcomes including normal growth, head circumference, and heart structure.

    Dear Editor, Nicolau's syndrome, also called embolia cutis medicamentosa or livedoid dermatitis, is a rare injection site reaction characterized by immediate intense pain at the injection site followed by erythema and a hemorrhagic patch with a livedoid reticular pattern after injections of non-steroidal anti-inflammatory drugs (NSAIDS), antiepileptics, antibiotics, antihistaminics, corticosteroids, etc. (1). To the best of our knowledge, only one case of Nicolau's syndrome has been reported after the use of triamcinolone acetonide. Herein we report two cases of Nicolau's syndrome caused by intramuscular injections of triamcinolone acetonide and diclofenac sodium, respectively. CASE 1 A 24-year-old male patient presented with severe pain and bluish discoloration of the right arm for 2 days, which he had noticed shortly after receiving an intramuscular injection of triamcinolone for recurrent episodes of urticaria by a local practitioner in the right deltoid region. On examination, there was a livedoid pattern of non-blanchable, violaceous discoloration extending from the deltoid area to the distal third of the forearm with associated induration (Figure 1, a, b). The local area was warm and tender to the touch. There was no regional lymphadenopathy, and the rest of the examination was normal. The patient's platelet count, bleeding and clotting times, prothrombin time, and international normalized ratio (INR) were unremarkable. There was no previous history of any bleeding disorder. The patient denied any intake of drugs like aspirin, warfarin, etc. Subsequently, the patient developed an ulcer on the forearm, which was managed by topical and systemic antibiotics to prevent any secondary infection of the wound. CASE 2 A 40-year-old female patient presented with complaints of pain and discoloration of the left gluteal region after receiving an intramuscular injection of diclofenac sodium for her arthralgia. A large ecchymotic patch with reticular borders was found on

    Full Text Available to improve treatment results in premature infants with neonatal respiratory distress syndrome (NRDS, by establishing developmental mechanisms and elaborating methods for its early diagnosis, treatment, and prevention. Material and methods. The paper analyzes the results of a clinical observation and laboratory, instrumental, immunological, morphological, and radiological studies of 320 premature neonates at 26—35 weeks gestational age. The following groups of neonates were identified: 1 40 premature neonatal infants without NRDS and with the physiological course of an early neonatal period (a comparison group; 2 190 premature neonates with severe NRDS in whom the efficiency of therapy with exogenous surfactants, such as surfactant BL versus curosurf, was evaluated; 3 90 premature newborn infants who had died from NRDS at its different stages. Results. The poor maternal somatic, obstetric, and gynecological histories in the early periods of the current pregnancy create prerequisites for its termination, favor the development of severe acute gestosis, and cause abnormal placental changes. Each gestational age is marked by certain placental changes that promote impaired uterineplacentalfetal blood flow and premature birth. Alveolar and bronchial epithelial damages, including those ante and intranatally, microcircula tory disorders play a leading role in the tanatogenesis of NRDS. Intranatal hypoxia and amniotic fluid aspiration are one of the important factors contributing to alveolar epithelial damage and NRDS in premature neonates. Exogenous surfactants prevent the development of hyaline membranes and are useful in the normalization of ventilation-perfusion relationships and lung biomechanical properties. Conclusion. This study could improve the diagnosis and treatment of NRDS, which assisted in reducing the duration of mechanical ventilation from 130±7.6 to 65±11.6 hours, the number of complications (the incidence of intragastric

Some hours after, he developed severe pain in his legs and a diagnosis of neuroleptic malignant syndrome (NMS was considered. Even with treatment for NMS he still complained of pain. A diagnosis of lower limb compartment syndrome (CS was done only 12 hours after the initial event, being submitted to fasciotomy in both legs, disclosing very pale muscles, due to previous ischemia. This syndrome was not explained only by facial surgery, his position and duration of the procedure. It can be explained by a sequence of events. He had a history of pain in his legs during physical exercises, usually seen in chronic compartment syndrome. He used to take anabolizant and venlafaxine, not previously related, and the agitation could be related to serotoninergic syndrome caused by interaction between venlafaxine and haloperidol. Rhabdomyolisis could lead to oedema and ischmemia in both anterior leg compartment. This report highlights the importance of early diagnosis of compartment syndrome, otherwise, even after fasciotomy, a permanent disability secondary to peripheral nerve compression could occur.Logo após ritidoplastia bilateral, um jovem de 25 anos apresentou agitação, necessitando uso de haloperidol.

    Nuts are rich in many bioactive compounds that can exert beneficial effects on cardiovascular health. We reviewed the evidence relating nut consumption and the metabolic syndrome (MetS) and its components. Nuts reduce the postprandial glycemic response; however, long-term trials of nuts on insulin resistance and glycemic control in diabetic individuals are inconsistent. Epidemiologic studies have shown that nuts may lower the risk of diabetes incidence in women. Few studies have assessed the association between nuts and abdominal obesity, although an inverse association with body mass index and general obesity has been observed. Limited evidence suggests that nuts have a protective effect on blood pressure and endothelial function. Nuts have a cholesterol-lowering effect, but the relation between nuts and hypertriglyceridemia and high-density lipoprotein cholesterol is not well established. A recent pooled analysis of clinical trials showed that nuts are inversely related to triglyceride concentrations only in subjects with hypertriglyceridemia. An inverse association was found between the frequency of nut consumption and the prevalence and the incidence of MetS. Several trials evaluated the effect of nuts on subjects with MetS and found that they may have benefits in some components. Compared with a low-fat diet, a Mediterranean diet enriched with nuts could be beneficial for MetS management. The protective effects on metabolism could be explained by the modulation of inflammation and oxidation. Further trials are needed to clarify the role of nuts in MetS prevention and treatment. © 2014 American Society for Nutrition.

Formation of such specialized virus-induced cellular microenvironments, which have been termed viroplasms, virus factories, or virus replication centers, complexes, or compartments, depends on molecular interactions between viral and cellular factors that participate in viral genome expression and replication and are in some cases associated with sites of virion assembly. These virus-induced compartments function not only to recruit and concentrate factors required for essential steps of the viral replication cycle but also to control the cellular mechanisms of antiviral defense. In this review, we summarize characteristic features of viral replication compartments from different virus families and discuss similarities in the viral and cellular activities that are associated with their assembly and the functions they facilitate for viral replication.

    Ishibashi, Hideaki

    In Japan, the world's fastest aging country, the locomotive syndrome that shows a decrease in the mobility due to dysfunctions of the locomotor organs is a major risk factor of long-term care need in the old age. Exercises and sports habits are well reviewed to lead to the improvement and maintenance of motor function, and exercises are also useful in the prevention of a number of musculoskeletal diseases. In addition, several trials with the exercise intervention indicated improvement in motor function, suggesting exercises could prevent the locomotive syndrome. In future, prevalence of exercise habits may lead to decrease the prevalence of locomotive syndrome, resulting in elongation of the healthy life span.

    Post-thrombotic syndrome (PTS) is a long-term complication of deep vein thrombosis (DVT) that is characterised by chronic pain, swelling, and skin changes in the affected limb. One of every three people with DVT will develop post-thrombotic complications within five years. Several non-pharmaceutical measures are used for prevention of post-thrombotic syndrome during the acute phase of DVT. These include elevation of the legs and compression therapy. Clinicians and guidelines differ in their assessment of the utility of compression therapy for treatment of DVT. This is an update of a review first published in 2003. To determine relative effectiveness and rate of complications when compression therapy is used in people with deep vein thrombosis (DVT) for prevention of post-thrombotic syndrome (PTS). For this update, the Cochrane Vascular Information Specialist (CIS) searched the Cochrane Vascular Specialised Register (20 March 2017) and CENTRAL (2017, Issue 2). The CIS also searched trial registries for details of ongoing or unpublished studies. We included randomised controlled trials (RCTs) and controlled clinical trials (CCTs) of compression therapy, such as bandaging and elastic stockings, in people with clinically confirmed DVT. The primary outcome was the occurrence of PTS. Two review authors (DK and EvL) identified and assessed titles and abstracts for relevance, and a third review author (DA) verified this assessment independently. Review authors imposed no restrictions on date or language of publications. Three review authors (DA, DK, EvL) used data extraction sheets to independently extract study data. We resolved disagreements by discussion. We identified 10 RCTs with a total of 2361 participants that evaluated compression therapy. The overall methodological quality of these trials was low. We used only five studies in meta-analysis owing to differences in intervention types and lack of data. Three studies compared elastic compression stockings (pressure

    Hepatorenal syndrome is a severe complication of cirrhosis. Treatment with terlipressin has currently the best efficacy pedigree, inducing hepatorenal syndrome reversal in a high proportion of patients. However, hepatorenal syndrome recurrence after terlipressin withdrawal is very common, especially in type 2 hepatorenal syndrome. Midodrine, an oral adrenergic vasoconstrictor, has been suggested to be an effective therapy in hepatorenal syndrome. To analyse the impact of treatment with midodrine after hepatorenal syndrome type 2 reversal induced by terlipressin on the prevention of hepatorenal syndrome recurrence. A case-control design was used. The outcome of 10 patients with hepatorenal syndrome type 2 treated successfully with terlipressin and then with midodrine (7.5-12.5mg/tid) was compared with that of an historical control group of hepatorenal syndrome type 2 patients responders to treatment with terlipressin. Patients and controls were matched by age, plasma renin activity (PRA) levels and severity of renal and liver failure. Cases and controls were similar with respect to pre-treatment with terlipressin. The hepatorenal syndrome recurrence probability was the same in the two groups (cases and control: 9/10, 90%, p=ns). No significant differences were found between cases and controls with respect to serum creatinine (1.9+/-0.1mg/dl vs. 2+/-0.2mg/dl), blood creatinine clearance (28+/-5ml/min vs. 24+/-5ml/min), urinary sodium excretion (12+/-6mequiv./d vs. 19+/-4mequiv./d) and PRA levels (17+/-3ng/ml/h) vs. 20+/-3ng/ml/h) after terlipressin withdrawal (p=ns). These results show that in patients responders to terlipressin hepatorenal syndrome recurrence is not different between patients treated with midodrine and subjects who did not receive vasoconstrictor treatment after terlipressin withdrawal. These data suggest that midodrine is not effective in preventing hepatorenal syndrome type 2 recurrence.

    Overtraining syndrome is a condition of maladapted physiology in the setting of excessive exercise without adequate rest. The exact etiology and pathogenesis are unknown and being investigated. Symptoms are multisystem in nature and often representative of underlying hormonal, immunologic, neurologic, and psychologic disturbances. Unfortunately, systematic review of the literature does not clearly direct diagnosis, management, or prevention. However, given the severity of symptoms and impairment to quality of life, prevention of overtraining syndrome should be considered by all who interact with endurance athletes. This article will provide suggestions for management of at-risk athletes despite absence of validated diagnostic tests and preventative measures.

    The shaken baby syndrome (SBS) is an extremely serious form of child abuse and a leading cause of death and disability in childhood. The syndrome usually occurs in infants younger than 1 year when a parent or a care-giver tries to stop the baby from crying by vigorous manual shaking. The repetitive oscillations with rotational acceleration of the head can result in injuries of both vascular and neuronal structures. The most frequent injuries associated with SBS include encephalopathy, retinal hemorrhages, and subdural hemorrhage. Fractures of the vertebrae, long bones, and ribs may also be associated with the syndrome. Victims of abuse have various presenting signs and symptoms ranging from irritability, decreased responsiveness and lethargy to convulsions, and death. Diagnosis is often difficult because usually parents or caregivers not tell the truth about what has happened to their child and because usually there is no external evidence of trauma. However, the syndrome might be suspected if the information provided are vague or changing and when the child presents with retinal hemorrhages, subdural hematoma, or fractures that cannot be explained by accidental trauma or other medical conditions. Of infants who are victims of SBS, approximately 15% to 38% die and 30% are at risk of long-term neurologic sequelae, including cognitive and behavioural disturbances, motor and visual deficits, learning deficits and epilepsy. Parents and caregivers must be warned about the dangers of shaking infants.

    Full Text Available Cardiovascular diseases are the major cause of disease and death not only in the general population, but also in patients with chronic kidney disease. The growing morbidity and mortality from chronic kidney disease and chronic heart failure conduce to an increase in cases of cardiorenal syndrome. Along with angiotensin-converting enzyme inhibitors, β-adrenoblockers, antianemic drugs, and diuretics, statins are appropriate and recommended by a number of trials for the prevention and treatment of the cardiorenal syndrome. Statins are effective in preventing the cardiorenal syndrome in patients at its high risk, improve quality of life and survival; in predialysis patients with chronic kidney disease, they may be secondary prevention of cardiovascular death.

    In Japan, physical therapists have usually been involved in physical therapy for patients with functional disorders associated with cerebrovascular or orthopedic diseases in hospitals. With the aging of Japanese society, the number of diseased people will progressively increase; thus, it is important to pay much more attention to disease prevention. In this regard, physical therapists are expected to play a new role in the field of preventive medicine. Metabolic syndrome or central obesity with multiple cardiometabolic risks is associated with a high risk of type 2 diabetes or cardiovascular diseases and is now a central target for early detection and intervention for disease prevention. The incidence of metabolic syndrome increases with age, and men showed a higher incidence of metabolic syndrome than women in all generations. We have been involved in the guidance of workers with metabolic syndrome for a long time, and we conducted a multicenter study to establish effective guidance for these worker. In this paper, we will use our evidence to discuss the role of physical therapists in providing guidance for preventing metabolic syndrome. We are now conducting worksite supporting exercise intervention for workers who were resistant to conventional lifestyle guidance. In addition, the unique role of physical therapists in this new trial will be introduced.

    2003-06-01

    Many morphologic, physical, and iatrogenic factors, such as deep grooves, pronounced intraoral temperature fluctuation, poor cavity preparation design, and wrong selection of restorative materials, may predispose posterior teeth to an incomplete fracture. The resulting cracked tooth syndrome is frequently associated with bizarre symptoms that may complicate diagnosis and can persist for many years. Epidemiologic data reveal that splits or fractures are the third most common cause of tooth loss in industrialized countries, primarily affecting maxillary molars and premolars and mandibular molars. This finding indicates that the cracked tooth syndrome is of high clinical importance. Thus, at-risk teeth should be reinforced early, for instance by castings with cusp coverage or by internal splinting with adhesive ceramic restorations.

    2016-09-01

    The aim of this study was to survey nursing students' Middle East respiratory syndrome-related knowledge, preventive behaviours and risk perception to examine the correlations among the variables during a Middle East respiratory syndrome outbreak. Middle East respiratory syndrome is a new viral respiratory illness. Nursing students who engage in clinical practice at hospitals may have been exposed to Middle East respiratory syndrome infection during the Middle East respiratory syndrome outbreak. This study was a descriptive cross-sectional survey. Participants (n = 249) were nursing students in their third or fourth year of the programme who were engaged in clinical practice for eight hours per day at the tertiary hospitals with Middle East respiratory syndrome patients. Knowledge, preventive behaviours and risk perception related to Middle East respiratory syndrome were measured using scales developed through a preliminary survey and validity testing. The subjects' knowledge level of Middle East respiratory syndrome was 84·4%; their practice of preventive behaviours was rated at 44·5%; and their risk perception rating was 2·4 out of 5. Middle East respiratory syndrome-related risk perception was significantly different according to gender and Middle East respiratory syndrome education. Middle East respiratory syndrome-related knowledge was significantly correlated with preventive behaviours and risk perception. Considering the low scores for items regarding knowledge and preventive behaviours, it is necessary to develop effective and systematic publicity and education programmes for nursing students. Enhancing Middle East respiratory syndrome-related knowledge by considering cooperation between hospitals and universities will sharpen nursing students' risk perception of the disease and effectively increase their preventive behaviours. Similar to other emerging infectious diseases, Middle East respiratory syndrome outbreaks may occur in other countries. The

    Our aim was to review the evidence for a reduction in the risk of sudden infant death syndrome (SIDS) with pacifier ("dummy" or "soother") use, to discuss possible mechanisms for the reduction in SIDS risk, and to review other possible health effects of pacifiers. There is a remarkably consistent reduction of SIDS with pacifier use. The mechanism by which pacifiers might reduce the risk of SIDS is unknown, but several mechanisms have been postulated. Pacifiers might reduce breastfeeding duration, but the studies are conflicting. It seems appropriate to stop discouraging the use of pacifiers. Whether it is appropriate to recommend pacifier use in infants is open to debate.

    Background: The study was done to compare the early pregnancy loss rate in women with polycystic ovarian syndrome who received or did not receive metformin in pregnancy. Study type, settings and duration: A case control interventional study carried out at Civil Hospital Karachi, Hamdard University Hospital and Private Gynaecology clinics from January 2005 to July 2008. Subjects and Methods Eighty two non diabetic patients with polycystic ovarian syndrome who became pregnant were included in the study. A questionnaire was filled for all patients that included information on basic demography and mean age, parity, weight. Fasting blood sugar and serum insulin levels were done for all these women. Only patients with raised insulin levels (more than 10 mu/l) were included in the study and all were offered to use oral metformin throughout pregnancy as 500 mg three times a day with folic acid supplements 5 mg once daily. Those who agreed to take the drug throughout pregnancy and to comply with the therapy were taken as cases, while those who did not agree to take the medicine acted as controls. Patients with other causes of recurrent pregnancy loss were excluded from the study. All pregnancies were followed using serial ultrasound examination to see any pregnancy loss in the two groups. Eighty two cases of polycystic ovaries with pregnancy were seen during the study period. All cases had raised serum insulin levels. Fifty patients agreed to take metformin through out pregnancy while, 32 cases did not agree to take metformin during pregnancy and thus acted as controls. The two groups did not differ in mean age, parity, weight and mean fasting blood sugar levels. Fasting insulin levels were high in metformin group (18.40 mu/l ) than in controls (12.53 mu/l). Missed abortion rate was significantly lower (12%) in metformin group than in controls (28%) (p<0.028). No congenital anomalies were found in both the groups on ultrasound at 16-19 weeks.

    Research on vibration syndrome in Japan began in the 1930s with studies of the disorder among railway, mining and shipyard workers. In 1947, the Ministry of Labor decided vibration syndrome among operators of rock drills and riveters etc. was an occupational disease. Industrial developments in the 1950s and 1960s promoted the survey of vibration syndrome in mining, stone quarrying and forestry. The Ministry of Labor (1965) and the National Personnel Agency (1966) legally recognized vibration syndrome among chain saw operators as an occupational disease. Guidelines for prevention and early therapy were issued in the 1970s and 80s. From the late 1970s into the 1980s, research focused on the clinical picture, diagnostic methods and therapy. In pathophysiology, advances were made in research into the autonomic nervous system during the 1980s. The 1970s and 80s saw a steady reduction in risk from technological change and working conditions, and advances in medical care, education and meteorological forecasting. A comprehensive prevention system established in the 1980s in the Japanese forest industry involved: 1) work restrictions, 2) an improved health care system, 3) advances in the design of vibrating tools, handle-warming devices, and 4) improved worker education. This comprehensive preventive system was legally introduced into other industries, resulting in a rapid decrease in the incidence of vibration syndrome in Japan.

    Full Text Available Recently, the use of plant-derived medicines is increasing interest in the prevention and treatment of a variety of disorders including metabolic syndromes. Metabolic syndrome is one of the major risk factors for cardiovascular diseases (CVDs and incidence of mortality worldwide. Scientific evidence suggests that Andrographis paniculata and its derived components, especially andrographolide (AGL and its analogs/derivatives have a broad spectrum of biological activities. This review aims to sketch the activity of AGL and its analogs/derivatives against the components of metabolic syndromes such as diabetes, hyperlipidemia, hypertension, and obesity. Additionally, AGL activity against CVDs is also summarized. The finding suggests that AGL and its analogs/derivatives have a potential role in the management of metabolic syndrome; however, more studies should be conducted to evaluate their effectiveness.

  11. Beta-blockers for preventing aortic dissection in Marfan syndrome.

    Science.gov (United States)

    Koo, Hyun-Kyoung; Lawrence, Kendra Ak; Musini, Vijaya M

    2017-11-07

    Marfan syndrome is a hereditary disorder affecting the connective tissue and is caused by a mutation of the fibrillin-1 (FBN1) gene. It affects multiple systems of the body, most notably the cardiovascular, ocular, skeletal, dural and pulmonary systems. Aortic root dilatation is the most frequent cardiovascular manifestation and its complications, including aortic regurgitation, dissection and rupture are the main cause of morbidity and mortality. To assess the long-term efficacy and safety of beta-blocker therapy as compared to placebo, no treatment or surveillance only in people with Marfan syndrome. We searched the following databases on 28 June 2017; CENTRAL, MEDLINE, Embase, Science Citation Index Expanded and the Conference Proceeding Citation Index - Science in the Web of Science Core Collection. We also searched the Online Metabolic and Molecular Bases of Inherited Disease (OMMBID), ClinicalTrials.gov and the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP) on 30 June 2017. We did not impose any restriction on language of publication. All randomised controlled trials (RCTs) of at least one year in duration assessing the effects of beta-blocker monotherapy compared with placebo, no treatment or surveillance only, in people of all ages with a confirmed diagnosis of Marfan syndrome were eligible for inclusion. Two review authors independently screened titles and abstracts for inclusion, extracted data and assessed trial quality. Trial authors were contacted to obtain missing data. Dichotomous outcomes will be reported as relative risk and continuous outcomes as mean differences with 95% confidence intervals. We assessed the quality of evidence using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. One open-label, randomised, single-centre trial including 70 participants with Marfan syndrome (aged 12 to 50 years old) met the inclusion criteria. Participants were randomly assigned to

  12. Numerical modelling of crural fascia mechanical interaction with muscular compartments.

    Pavan, Piero G; Pachera, Paola; Natali, Arturo N

    2015-05-01

    The interaction of the crural fascia with muscular compartments and surrounding tissues can be at the origin of different pathologies, such as compartment syndrome. This pathology consists in the onset of excessive intracompartmental pressure, which can have serious consequences for the patient, compromising blood circulation. The investigation of compartment syndrome etiology also takes into account the alteration of crural fascia mechanical properties as a cause of the syndrome, where the fascial stiffening would result in the rise of intracompartmental pressure. This work presents a computational approach toward evaluating some biomechanical aspects of the problem, within the context of a more global viewpoint. Finite element analyses of the interaction phenomena of the crural fascia with adjacent regions are reported here. This study includes the effects of a fascial stiffness increase along the proximal-distal direction and their possible clinical implications. Furthermore, the relationship between different pre-strain levels of the crural fascia in the proximal-distal direction and the rise of internal pressure in muscular compartments are considered. The numerical analyses can clarify which aspects could be directly implied in the rise of compartment syndrome, leading to greater insight into muscle-fascia mechanical phenomena, as well as promoting experimental investigation and clinical analysis of the syndrome. © IMechE 2015.

    2011-01-01

    The term "economic class syndrome" is generally used to describe the occurrence of venous thromboembolism (VTE) in travelers after long-distance airline travel in economic class. However, cases of VTE have also been reported in business class travelers and in subjects exposed to prolonged periods of immobilization while using other forms of transportation such as automobile, train, and bus. VTE manifests with deep vein thrombosis and pulmonary embolism but may also present with less severe, reversible manifestations such as headache, vertigo, and respiratory symptoms. Epidemiological studies have shown that the risk of VTE doubles following airline travel lasting longer than four hours. The risk of VTE increases with increased duration of air travel even in the presence of multiple stop-overs. In subjects with known risk factors, incidence of VTE depends on the degree of risk (low, medium, high) and on the duration of the flight. The main factor leading to VTE is prolonged immobilization and the pathogenesis is based on Virchow's triad: venous stasis, vessel wall injury, and hypercoagulability of blood. Specific characteristics of airline travel such as jet lag, low air quality and dehydration may increase the risk of VTE with respect to other forms of travel. This article discusses epidemiological aspects and pathogenesis of travel-related VTE and prophylactic measures that should be undertaken.

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

    Full Text Available 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.

  15. Dietary fiber in the prevention and treatment of metabolic syndrome: a review.

    Inclusion of fiber in the diet has been linked to the prevention of a range of illnesses and conditions. This review contains several ideas about the possible benefits of dietary fiber intake in patients with metabolic syndrome. The principal beneficial effects of a fiber-rich diet in these patients are: prevention of obesity, improved glucose levels, and control of the profile of blood lipids. We now also know that dietary fiber may favor the control of arterial blood pressure. Animal experiments have also shown the benefit of different types of fiber on these variables. Of particular relevance are the studies using obese Zucker rats, which present similar anomalies to those seen in patients with metabolic syndrome. There is therefore a growing interest in discovering new sources of natural fiber. Some of these different kinds of fiber may then be used as functional ingredients to obtain foods with properties that are beneficial to health.

    In Marfan syndrome, with dilatation of the aortic root secondary to an underlying connective tissue defect, pregnancy can cause hemodynamic stress leading to the development of an aortic aneurysm and even a fatal aortic dissection. In the presence of existing aortic root enlargement and a family history of aortic dissection, preventative elective surgery is suggested. Aortic root replacement with or without a valve-sparing procedure is superior to total aortic root replacement with ...

    The translational path from pharmacological insight to effective therapy can be a long one. We aim to describe the management of Marfan syndrome as a case-example of how pharmacological and genomic insights can contribute to improved therapy. We undertook a literature search for studies of Marfan syndrome, to identify milestones in description, understanding and therapy of the syndrome. From the studies retrieved we then weaved an evidence-based description of progress. Marfan syndrome shows considerable heterogeneity in clinical presentation. It relies on defined clinical criteria with confirmation based on FBN1 mutation testing. Surgical advances have prolonged life in Marfan syndrome. First-line prophylaxis of complications with β-adrenoceptor blockers became established on the basis that reduction of aortic pressure and heart rate would help. Over-activity of proteinases, first suggested in 1980, has since been confirmed by evidence of over-expression of matrix metalloproteinases (MMP), notably MMP-2 and MMP-9. The search for MMP inhibitors led to the evaluation of doxycycline, and both animal studies and small trials, provided early evidence that this widely used antimicrobial agent was useful. Identification of the importance of TGF-β led to evaluation of angiotensin II type I receptor (AT1R) blockers with highly promising results. Combination prophylactic therapy would appear rational. Pharmacological and genomic research has provided good evidence that therapy with losartan and doxycycline would prevent the aortic complications of Marfan syndrome. If on-going well designed trials confirm their efficacy, the outlook for Marfan syndrome patients would be improved considerably. PMID:21276043

    2005-10-01

    Full Text Available INTRODUCTION: The urofacial or Ochoa syndrome is a rare disease characterized by the presence of functional obstructive uropathy associated with peculiar facial features when patients attempt to smile or laugh. Unfortunately, many of these patients remain without proper diagnosis or adequate treatment due to lack of recognition of the disease. This can ultimately result in upper tract deterioration and eventual renal failure. We present our experience with this rare syndrome. MATERIALS AND METHODS: We identified 3 patients who presented initially with acute renal failure, urinary tract infection (UTI and severe dysfunctional elimination. All patients were thoroughly evaluated, including screening for spinal cord anomalies, and were subsequently diagnosed with urofacial syndrome. RESULTS: At the outset, the two older patients (aged 4 and 9 years presented with the typical facial features when attempting to smile or laugh. One patient in the newborn period presented with urinary and fecal retention and septicemia and, to our knowledge, represents the youngest case of urofacial syndrome reported so far. All patients were evaluated with ultrasonography, renal scan, voiding cystourethrogram (VCUG and urodynamics. Findings included hydronephrosis and a thick-walled, trabeculated bladder with poor compliance and detrusor hypereflexia respectively in each patient. All were subsequently treated with clean intermittent catheterization (CIC, antibiotic prophylaxis and anticholinergic therapy. One patient required appendicovesicostomy for CIC due to discomfort secondary to a sensate urethra. CONCLUSIONS: Our series demonstrates that early recognition of this rare syndrome is necessary to adequately treat and prevent upper tract deterioration in these unique individuals. Although the urofacial is difficult to diagnose in infants, cognizance must be maintained in order to prevent severe subsequent sequalae.

    It is essential that symptomatic fractures of teeth be suitably diagnosed to prevent propagation of the fracture and continuation of the symptoms. The importance of understanding the mechanism and progression of fractures within teeth is essential when considering the management of fractures within teeth. The relation of the fracture line to the pulp, periodontal ligament and root will influence the management protocols for the involved teeth. When does a Cracked Tooth Syndrome (CTS) become a cracked tooth i.e., unrestorable? Consideration is also required regarding when endodontic treatment should be commenced. Further, suitable-coronal restoration of teeth is required to prevent propagation of the fracture line and persistence of the symptoms. Patients diagnosed with CTS should be counselled in strategies to prevent CTS in other teeth.

    Compartment syndrome is a constellation of symptoms and signs associated with abnormally elevated tissue pressure in the skeletal muscle of the extremities. It is manifested in anatomic locations where muscles are enveloped in fasciae. The case of a lower extremity compartment syndrome in a 71-year-old male patient who underwent coronary artery bypass grafting (CABG) and simultaneous aortic valve surgery is reported. Preoperative evaluation revealed severe peripheral vascular disease. The patient underwent triple CABG using the left internal thoracic artery and two vein grafts. The right great saphenous vein was used for these vein grafts. The aortic valve was replaced with a biologic prosthesis. On postoperative day 1, the patient complained of pain and oedema in the right calf. The next day, symptoms worsened, with marked sensory loss, motor weakness and foot drop in the affected limb. Triplex ultrasonography excluded deep vein thrombosis. Compartment syndrome was diagnosed and successfully managed by fasciotomy. This case illustrates that compartment syndrome may, although rarely, be a complication of CABG.

    Full Text Available The sudden infant death syndrome (SIDS, with the load of mystery surrounding its causes and with the devastating impact on the affected families, remains the greatest contributor to post-neonatal mortality during the first year of life. Following a succinct review of the non-cardiac genetic factors, which have been associated with SIDS, we focus on the cardiac hypothesis for SIDS and specifically on those diseases produced by cardiac ion channel mutations, the so-called channelopathies. Special attention is devoted to the fact that these causes of SIDS, and especially the long QT syndrome, are preventable if diagnosed in time. This highlights the importance of neonatal ECG screening and carries a number of practical implications, including medico-legal considerations.

    Full Text Available Tea, a popular beverage made from leaves of the plant Camellia sinensis, has been studied extensively in recent decades for its beneficial health effects in the prevention of obesity, metabolic syndrome, diabetes, cancer, and other diseases. Whereas these beneficial effects have been convincingly demonstrated in most laboratory studies, results from human studies have not been consistent. Some studies demonstrated that weight reduction, alleviation of metabolic syndrome and risk reduction in diabetes were only observed in individuals who consume 3–4 cups of tea (600–900 mg tea catechins or more daily. This chapter reviews some of these studies, the possible mechanisms of actions of tea constituents, and the challenges in extrapolating laboratory studies to human situations.

    Hyperuricemia and tumor lysis syndrome (TLS) are complications that can arise from treatment of rapidly proliferating and drug-sensitive neoplasms. Clinical trials have shown rasburicase, a recombinant urate oxidase to be more effective than allopurinol for the prevention and treatment of malignancy-associated hyperuricemia. We investigated the safety and efficacy of rasburicase in the AIEOP centers' experience. We reviewed the data of 26 children with malignancy at risk for TLS, submitted to treatment (group 1) or prophylaxis (group 2) of acute hyperuricemia with rasburicase (0.20 mg/kg intravenously daily) for a median period of 4 days. Rasburicase produced a significant decrease in uric acid concentrations in all the patients. The control of uric acid levels was obtained in both the groups within 24 h of the first dose with a response rate of 100% (group 1) and 93% (group 2). Normalization of creatinine and phosphorus levels was obtained in 5 and 4 days respectively. Tolerance was excellent without toxicity. These data confirm that rasburicase is a safe, highly and rapidly effective agent in the treatment and prevention of malignancy-associated acute hyperuricemia and could be considered the treatment of choice to prevent tumor lysis syndrome in children at high risk for this metabolic complication.

Several risk factors for cardiovascular disease, such as visceral obesity, glucose intolerance, arterial hypertension, and dyslipidemia commonly cluster together as a condition currently known as metabolic syndrome. Thus far, insulin resistance, and endothelial dysfunction are the primary events of the metabolic syndrome. Several groups have recommended clinical criteria for the diagnosis of metabolic syndrome in adults. Nonetheless, in what concerns children and adolescents, there are no unified definitions, and modified adult criteria have been suggested by many authors, despite major problems. Some pediatric disease states are at risk for premature cardiovascular disease, with clinical coronary events occurring very early in adult life. Survivors of specific pediatric cancer groups, particularly acute lymphocytic leukemia, central nervous system tumors, sarcomas, lymphomas, testicular cancer, and following bone marrow transplantation, may develop metabolic syndrome traits due to: hormonal deficiencies (growth hormone deficiency, thyroid dysfunction, and gonadal failure, drug or radiotherapy damage, endothelial impairment, physical inactivity, adipose tissue dysfunction, and/or drug-induced magnesium deficiency. In conclusion, some primary and secondary prevention remarks are proposed in order to reduce premature cardiovascular disease risk in this particular group of patients.Keywords: metabolic syndrome X, cardiovascular diseases, insulin resistance, obesity, growth hormone

    We attempted here the delineation of the natural history of the disease and corresponding prevention levels (NHD and PL) of the Wiedemann-Beckwith syndrome according to the classical model of Leavell and Clark for infectious-contagious diseases. This proposal was based on our own series of 39 patients and our previous reports on the didactics of the NHD and PL model, as well as on the relevant literature; with this approach we obtained an useful model which includes the health-disease status, the analysis of risk factors and the integration of the clinical practice with socio-epidemiological medicine. Furthermore, the NHD and PL model allow the selection of the preventive management depending on the clinical stage, namely health or disease. This approach to a Mendelian condition emphasizes that the Leavell and Clark concepts can be advantageously applied to any genetic disease.

    Monoallelic germline mutations in one of the DNA mismatch repair (MMR) genes cause Lynch syndrome, with a high lifetime risks of colorectal and endometrial cancer at adult age. Less well known, is the constitutional mismatch repair deficiency (CMMRD) syndrome caused by biallelic germline mutations in MMR genes. This syndrome is characterized by the development of childhood cancer. Patients with CMMRD are at extremely high risk of developing multiple cancers including hematological, brain and intestinal tumors. Mutations in MMR genes impair DNA repair and therefore most tumors of patients with CMMRD are hypermutated. These mutations lead to changes in the translational reading frame, which consequently result in neoantigen formation. Neoantigens are recognized as foreign by the immune system and can induce specific immune responses. The growing evidence on the clinical efficacy of immunotherapies, such as immune checkpoint inhibitors, offers the prospect for treatment of patients with CMMRD. Combining neoantigen-based vaccination strategies and immune checkpoint inhibitors could be an effective way to conquer CMMRD-related tumors. Neoantigen-based vaccines might also be a preventive treatment option in healthy biallelic MMR mutation carriers. Future studies need to reveal the safety and efficacy of immunotherapies for patients with CMMRD. Copyright © 2017 The Author(s). Published by Elsevier B.V. All rights reserved.

    Wissing, Karl Martin; Pipeleers, Lissa

    2014-04-01

    The prevalence of the metabolic syndrome in dialysis patients is high and further increases after transplantation due to weight gain and the detrimental metabolic effects of immunosuppressive drugs. Corticosteroids cause insulin resistance, hyperlipidemia, abnormal glucose metabolism and arterial hypertension. The calcineurin inhibitor tacrolimus is diabetogenic by inhibiting insulin secretion, whereas cyclosporine causes hypertension and increases cholesterol levels. Mtor antagonists are responsible for hyperlipidemia and abnormal glucose metabolism by mechanisms that also implicate insulin resistance. The metabolic syndrome in transplant recipients has numerous detrimental effects such as increasing the risk of new onset diabetes, cardiovascular disease events and patient death. In addition, it has also been linked with accelerated loss of graft function, proteinuria and ultimately graft loss. Prevention and management of the metabolic syndrome are based on increasing physical activity, promotion of weight loss and control of cardiovascular risk factors. Bariatric surgery before or after renal transplantation in patients with body mass index >35 kg/m(2) is an option but its long term effects on graft and patient survival have not been investigated. Steroid withdrawal and replacement of tacrolimus with cyclosporine facilitate control of diabetes, whereas replacement of cyclosporine and mtor antagonists can improve hyperlipidemia. The new costimulation inhibitor belatacept has potent immunosuppressive properties without metabolic adverse effects and will be an important component of immunosuppressive regimens with better metabolic risk profile. Medical treatment of cardiovascular risk factors has to take potential drug interactions with immunosuppressive medication and drug accumulation due to renal insufficiency into account.

TLS is clinically characterized by acute renal failure, hyperuricemia, hyperkalemia, hyperphosphatemia, and hypocalcemia. While limited options are available for treating TLS, identifying patients at high risk for developing TLS and prevention in high-risk patients remain an important aspect in the treatment of cancer patients. In general, treatment of TLS consists of intensive hydration, stimulation of diuresis, and, more specifically, in the use of allopurinol and rasburicase. Rasburicase, a recombinant urate oxidase, rapidly and effectively reduces hyperuricemia, which subsequently significantly decreases the risk of acute renal failure and other clinical manifestations of TLS. For this review, a comprehensive literature search using the term “tumor lysis syndrome” and/or “rasburicase” was performed considering articles listed in MEDLINE. Incidence, prevention, and therapy of TLS with a special focus on the role of rasburicase are discussed. We evaluated 120 relevant articles including 35 case reports, 32 clinical trials, and 14 meta-analyses. Keywords: rasburicase, tumor lysis syndrome, hyperuricemia, acute kidney injury

    To present clinical information relevant to acute respiratory distress syndrome (ARDS) and its appearance in chiropractic acute care practice. The National Library of Medicine MEDLINE database was used, along with the bibliographies of selected articles and textbooks commonly found in chiropractic college libraries and bookstores. Clinical studies from the English literature were selected if they pertained to incidence, clinical relevancy, or the association of ARDS with commonly-seen diagnoses in chiropractic neuromusculoskeletal or orthopedic practice. All relevant studies identified by the search were evaluated based on information pertinent to chiropractic management of acute care patients. ARDS is a pulmonary distress syndrome with a high mortality rate. Recognizable indications for the possible development of ARDS include chest pain, head injury, and thoracic spine pain with or without trauma. Clinical evaluation, radiographic findings, and laboratory findings are presented to assist practitioners in identifying this disease process of multiple etiology. A study of the basic pathophysiologic processes that occur in the formation of ARDS is presented to help practitioners gain clinical appreciation. Strategies for preventing respiratory distress in chiropractic patients are also presented and include use of the postural position and the clinical maxim of "slow, deep breathing despite pain" to lessen incident rates of subjects at risk. Although ARDS may not be prevalent in chiropractic practice, it is important for physicians to be aware of the clinical basics (including its pathophysiology), its medical significance, and the preventive strategies that may be used to minimize its occurrence. This basic understanding will further advance knowledge of this disease complex.

    This paper aims to develop and analyze the effects of a socio-ecological model-based intervention program for preventing metabolic syndrome (MetS) among office workers. The intervention program was developed using regular health examinations, a "health behavior and need" assessment survey among workers, and a focus group study. According to the type of intervention, subjects took part in three groups: health education via an intranet-based web magazine (Group 1), self-monitoring with the U-health system (Group 2), and the target population who received intensive intervention (Group 3). The intervention programs of Group 1 and Group 2, which relied on voluntary participation, did not show significant effects. In Group 3, which relied on targeted and proactive programs, showed a decrease in waist circumference and in fasting glucose ( p light of the effectiveness of the intensive intervention strategy for metabolic syndrome prevention among workers used in this study, companies should establish targeted and proactive health care programs rather than providing a healthcare system that is dependent on an individual's voluntary participation.

    During refeeding syndrome-a well-known and dreaded complication of weight-restauration in anorexia nervosa-a shift of electrolytes and fluid can occur in malnourished patients and might therefore lead to-potentially fatal-cardiovascular, respiratory and neurological symptoms. Causes of this are metabolic and hormonal changes during re-establishment of a carbohydrate-rich diet. This syndrome is most commonly associated with hypophosphatemia, which can however be accompanied by other chemical laboratory abnormalities. Standardized guidelines for the prevention and management of the refeeding syndrome have not yet been established. In case and cohort studies different low- and high-calorie diet protocols led to comparable results with similar complication rates. A focus should be placed on prevention of serious complications by careful monitoring. The pathophysiology, the main constituents in the development of the refeeding syndrome, recommendations for risk assessment and treatment, and current evidence are discussed.

METHODS: Wistar rats receiving fructose overload (F in drinking water (100 g/l were concomitantly trained on a treadmill (FT for 10 weeks or kept sedentary. These rats were compared with a control group (C. Obesity was evaluated by the Lee index, and glycemia and insulin tolerance tests constituted the metabolic evaluation. Blood pressure was measured directly (Windaq, 2 kHz, and echocardiography was performed to determine left ventricular morphology and function. Statistical significance was determined by one-way ANOVA, with significance set at p<0.05. RESULTS: Fructose overload induced a metabolic syndrome state, as confirmed by insulin resistance (F: 3.6 ± 0.2 vs. C: 4.5 ± 0.2 mg/dl/min, hypertension (mean blood pressure, F: 118 ± 3 vs. C: 104 ± 4 mmHg and obesity (F: 0.31±0.001 vs. C: 0.29 ± 0.001 g/mm. Interestingly, fructose overload rats also exhibited diastolic dysfunction. Exercise training performed during the period of high fructose intake eliminated all of these derangements. The improvements in metabolic parameters were correlated with the maintenance of diastolic function. CONCLUSION: The role of exercise training in the prevention of metabolic and hemodynamic parameter alterations is of great importance in decreasing the cardiac morbidity and mortality related to metabolic syndrome.

    Ovarian hyperstimulation syndrome (OHSS) is a serious iatrogenic complication that can occur during assisted reproductive techniques. The aim of this study is to investigate the effects of the leukotriene receptor antagonist (montelukast) treatment in prevention of OHSS and compare to cabergoline treatment. Twenty-four immature female Wistar rats were assigned to four groups. Group 1 was the control group. In the remaining three groups, OHSS was induced through ovarian stimulation with gonadotropins. No treatment was given to Group 2. Group 3 was administered a low-dose 100 mg/kg cabergoline treatment and Group 4 was received 20 mg/kg montelukast. Body weight, ovarian weight, vasculary permability (VP), peritoneal fluid vascular endothelial growth factor (VEGF) values and VEGF immune-expression were compared between the groups. Both cabergoline and montelukast prevented progression of OHSS compared to the OHSS group. Body weight, ovarian weight, VP, peritoneal fluid VEGF values and VEGF expression were significantly lower in both cabergoline- and montelukast-treated rats than in those not treated OHSS group. In conclusion, montelukast is an effective option for prevention of OHSS, as well as cabergoline. Montelukast may be a new treatment option to prevent and control the OHSS.

    There is a need for an improvement over current NASA Extravehicular Activity (EVA) technology. The technology must allow the capacity for quicker, more efficient egress/ingress, allow for shirtsleeve suit maintenance, be compact in transport, and be applicable to environments ranging from planetary surface (partial-g) to orbital or deep space zero-g environments. The technology must also be resistant to dust and other foreign contaminants that may be present on or around a planetary surface. The technology should be portable, and be capable of docking with a variety of habitats, ports, stations, vehicles, and other pressurized modules. The Dual-Compartment Inflatable Suitlock (DCIS) consists of three hard inline bulkheads, separating two cylindrical membrane-walled compartments. The Inner Bulkhead can be fitted with a variety of hatch types, docking flanges, and mating hardware, such as the Common Berthing Mechanism (CBM), for the purpose of mating with vehicles, habitats, and other pressurized modules. The Inner Bulkhead and Center Bulkhead function as the end walls of the Inner Compartment, which during operations, would stay pressurized, either matching the pressure of the habitat or acting as a lower-pressure transitional volume. The Inner Compartment contains donning/doffing fixtures and inner suit-port hatches. The Center Bulkhead has two integrated suit-ports along with a maintenance hatch. The Center Bulkhead and Outer Bulkhead function as the end walls of the Outer Compartment, which stays at vacuum during normal operations. This allows the crewmember to quickly don a suit, and egress the suitlock without waiting for the Outer Compartment to depressurize. The Outer Compartment can be pressurized infrequently for both nominal and off-nominal suit maintenance tasks, allowing shirtsleeve inspections and maintenance/repair of the environmental suits. The Outer Bulkhead has a pressure-assisted hatch door that stays open and stowed during EVA operations, but can

    The importance of metabolic syndrome (MetS) lies in its associated risk of cardiovascular disease and type 2 diabetes, as well as other harmful conditions such as nonalcoholic fatty liver disease. In this report, the available scientific evidence on the associations between lifestyle changes and MetS and its components is reviewed to derive recommendations for MetS prevention and management. Weight loss through an energy-restricted diet together with increased energy expenditure through physical activity contribute to the prevention and treatment of MetS. A Mediterranean-type diet, with or without energy restriction, is an effective treatment component. This dietary pattern should be built upon an increased intake of unsaturated fat, primarily from olive oil, and emphasize the consumption of legumes, cereals (whole grains), fruits, vegetables, nuts, fish, and low-fat dairy products, as well as moderate consumption of alcohol. Other dietary patterns (Dietary Approaches to Stop Hypertension, new Nordic, and vegetarian diets) have also been proposed as alternatives for preventing MetS. Quitting smoking and reducing intake of sugar-sweetened beverages and meat and meat products are mandatory. Nevertheless, there are inconsistencies and gaps in the evidence, and additional research is needed to define the most appropriate therapies for MetS. In conclusion, a healthy lifestyle is critical to prevent or delay the onset of MetS in susceptible individuals and to prevent cardiovascular disease and type 2 diabetes in those with existing MetS. The recommendations provided in this article should help patients and clinicians understand and implement the most effective approaches for lifestyle change to prevent MetS and improve cardiometabolic health. © The Author(s) 2017.

    2018-01-01

    Epidemiologic studies from several countries have found that mortality rates associated with the metabolic syndrome are inversely associated with coffee consumption. Metabolic syndrome can lead to arteriosclerosis by endothelial dysfunction, and increases the risk for myocardial and cerebral infarction. Accordingly, it is important to understand the possible protective effects of coffee against components of the metabolic syndrome, including vascular endothelial function impairment, obesity and diabetes. Coffee contains many components, including caffeine, chlorogenic acid, diterpenes and trigonelline. Studies have found that coffee polyphenols, such as chlorogenic acids, have many health-promoting properties, such as antioxidant, anti-inflammatory, anti-cancer, anti-diabetes, and antihypertensive properties. Chlorogenic acids may exert protective effects against metabolic syndrome risk through their antioxidant properties, in particular toward vascular endothelial cells, in which nitric oxide production may be enhanced, by promoting endothelial nitric oxide synthase expression. These effects indicate that coffee components may support the maintenance of normal endothelial function and play an important role in the prevention of metabolic syndrome. However, results related to coffee consumption and the metabolic syndrome are heterogeneous among studies, and the mechanisms of its functions and corresponding molecular targets remain largely elusive. This review describes the results of studies exploring the putative effects of coffee components, especially in protecting vascular endothelial function and preventing metabolic syndrome.

    Programmed cell death or apoptosis is a prominent feature of low-risk myelodysplastic syndromes (MDS), although the underlying mechanism remains controversial. High-risk MDS have less apoptosis associated with increased expression of the prosurvival BCL2-related proteins. To address the mechanism and pathogenic role of apoptosis and BCL2 expression in MDS, we used a mouse model resembling human MDS, in which the fusion protein NUP98-HOXD13 (NHD13) of the chromosomal translocation t(2;11)(q31;p15) is expressed in hematopoietic cells. Hematopoietic stem and progenitor cells from 3-month-old mice had increased rates of apoptosis associated with increased cell cycling and DNA damage. Gene expression profiling of these MDS progenitors revealed a specific reduction in Bcl2. Restoration of Bcl2 expression by a BCL2 transgene blocked apoptosis of the MDS progenitors, which corrected the macrocytic anemia. Blocking apoptosis also restored cell-cycle quiescence and reduced DNA damage in the MDS progenitors. We expected that preventing apoptosis would accelerate malignant transformation to acute myeloid leukemia (AML). However, contrary to expectations, preventing apoptosis of premalignant cells abrogated transformation to AML. In contrast to the current dogma that overcoming apoptosis is an important step toward cancer, this work demonstrates that gaining a survival advantage of premalignant cells may delay or prevent leukemic progression.

    2009-01-01

    The approach to preventing meconium aspiration syndrome (MAS) in the newborn has changed markedly over the last 30 years. In the late 1970s, all infants born through meconium-stained amniotic fluid (MSAf) had upper-airway suctioning before delivery of the shoulders and then had tracheal intubation and suctioning in the delivery room. Now suctioning of the upper airway is no longer recommended, and only “depressed” infants are intubated for tracheal suctioning. The incidence of MAS and the associated high mortality rate have both declined significantly over time. This is due to improved antepartum and intrapartum obstetrical management as well as the postdelivery resuscitation of the neonate born through MSAf. MAS is no longer considered to be solely a postnatal disorder that is preventable with routine delivery room suctioning of the trachea; rather, it is considered a complex and multifactorial disorder with antenatal as well as intrapartum factors. The incidence and severity of MAS have been positively affected by a combined obstetrical and neonatal approach to the infant born through MSAf. In this article, we detail our experience at Baylor University Medical Center with MAS and its prevention and review the current literature. PMID:19381312

    Full Text Available Abstract Ovarian hyperstimulation syndrome (OHSS is the most serious complication of controlled ovarian stimulation (COS as part of assisted reproductive technologies (ART. While the safety and efficacy of ART is well established, physicians should always be aware of the risk of OHSS in patients undergoing COS, as it can be fatal. This article will briefly present the pathophysiology of OHSS, including the key role of vascular endothelial growth factor (VEGF, to provide the foundation for an overview of current techniques for the prevention of OHSS. Risk factors and predictive factors for OHSS will be presented, as recognizing these risk factors and individualizing the COS protocol appropriately is the key to the primary prevention of OHSS, as the benefits and risks of each COS strategy vary among individuals. Individualized COS (iCOS could effectively eradicate OHSS, and the identification of hormonal, functional and genetic markers of ovarian response will facilitate iCOS. However, if iCOS is not properly applied, various preventive measures can be instituted once COS has begun, including cancelling the cycle, coasting, individualizing the human chorionic gonadotropin trigger dose or using a gonadotropin-releasing hormone (GnRH agonist (for those using a GnRH antagonist protocol, the use of intravenous fluids at the time of oocyte retrieval, and cryopreserving/vitrifying all embryos for subsequent transfer in an unstimulated cycle. Some of these techniques have been widely adopted, despite the scarcity of data from randomized clinical trials to support their use.

    2016-01-21

    Craniofacial anomalies account for approximately one-third of all birth defects and are a significant cause of infant mortality. Since the majority of the bones, cartilage and connective tissues that comprise the head and face are derived from a multipotent migratory progenitor cell population called the neural crest, craniofacial disorders are typically attributed to defects in neural crest cell development. Treacher Collins syndrome (TCS) is a disorder of craniofacial development and although TCS arises primarily through autosomal dominant mutations in TCOF1, no clear genotype-phenotype correlation has been documented. Here we show that Tcof1 haploinsufficiency results in oxidative stress-induced DNA damage and neuroepithelial cell death. Consistent with this discovery, maternal treatment with antioxidants minimizes cell death in the neuroepithelium and substantially ameliorates or prevents the pathogenesis of craniofacial anomalies in Tcof1(+/-) mice. Thus maternal antioxidant dietary supplementation may provide an avenue for protection against the pathogenesis of TCS and similar neurocristopathies.

    2017-12-01

    Polycystic ovary syndrome (PCOS) is recognized as one of the most common endocrinopathies in women of reproductive age, associated with metabolic sequelae which includes increased risk factors for impaired glucose tolerance (IGT), type 2 diabetes mellitus (DM2) and cardiovascular disease (CVD). The adverse effects of DM2 affects a woman throughout her lifespan. Health care expenditure of DM2 highlights the need for prevention through appropriate screening, diagnosis and intervention. Lifestyle modification (LSM) programs that include diet and/or physical activity are suggested for patients characterized as prediabetic to delay the onset of adult DM2. Diet (i.e. low carbohydrate), combination of aerobic and resistance exercise with high intensity interval training (HIT) 150 to 175min/week with resistance exercise 2 to 3days/week and weight loss may be valuable supporters in the fight against IR, IGT and DM2 associated with PCOS.

    2014-01-22

    Infantile spasms are a catastrophic form of pediatric epilepsy with inadequate treatment. In patients, mutation of ARX, a transcription factor selectively expressed in neuronal precursors and adult inhibitory interneurons, impairs cell migration and causes a major inherited subtype of the disease X-linked infantile spasms syndrome. Using an animal model, the Arx((GCG)10+7) mouse, we determined that brief estradiol (E2) administration during early postnatal development prevented spasms in infancy and seizures in adult mutants. E2 was ineffective when delivered after puberty or 30 days after birth. Early E2 treatment altered mRNA levels of three downstream targets of Arx (Shox2, Ebf3, and Lgi1) and restored depleted interneuron populations without increasing GABAergic synaptic density. Postnatal E2 treatment may induce lasting transcriptional changes that lead to enduring disease modification and could potentially serve as a therapy for inherited interneuronopathies.

    We reviewed 50 patients with Marfan syndrome who underwent surgery for aortic root pathologies comprising a root aneurysm without (n = 25; group A) and with (n = 25; group B) dissection. Aortic root repair included Bentall (n = 37) and valve-sparing (n = 13) procedures. Hospital mortality was 4.0%. Twenty-two patients required 36 repeat surgeries on the distal aorta. The main indication for re-intervention was the dilation of the false lumen. In group A, the distal aorta was stable for up to 7 years, but new dissection developed in 5 (33.3%) of the 15 patients who were followed up for >7 years after the root repair. Actuarial survival including operative mortality was 88.1 and 65.0% at 10 and 20 years, respectively; groups A and B did not significantly differ. Rates of freedom from all-cause death, new dissection or repeated aortic surgery were 60.1, 44.5 and 26.0% at 5, 10 and 15 years, respectively. Group A was significantly better than group B. Prophylactic aortic root repair apparently reduces the likelihood of overall adverse events, but it cannot guarantee the prevention of further aortic dissection. A multidisciplinary approach is needed for patients with Marfan syndrome.

    Full Text Available The red seaweed, Kappaphycus alvarezii, was evaluated for its potential to prevent signs of metabolic syndrome through use as a whole food supplement. Major biochemical components of dried Kappaphycus are carrageenan (soluble fiber ~34.6% and salt (predominantly potassium (K 20% with a low overall energy content for whole seaweed. Eight to nine week old male Wistar rats were randomly divided into three groups and fed for 8 weeks on a corn starch diet, a high-carbohydrate, high-fat (H diet, alone or supplemented with a 5% (w/w dried and milled Kappaphycus blended into the base diet. H-fed rats showed symptoms of metabolic syndrome including increased body weight, total fat mass, systolic blood pressure, left ventricular collagen deposition, plasma triglycerides, and plasma non-esterified fatty acids along with fatty liver. Relative to these obese rats, Kappaphycus-treated rats showed normalized body weight and adiposity, lower systolic blood pressure, improved heart and liver structure, and lower plasma lipids, even in presence of H diet. Kappaphycus modulated the balance between Firmicutes and Bacteroidetes in the gut, which could serve as the potential mechanism for improved metabolic variables; this was accompanied by no damage to the gut structure. Thus, whole Kappaphycus improved cardiovascular, liver, and metabolic parameters in obese rats.

    Full Text Available Introduction. Intermediate syndrome (IMS was described a few decades ago, however, there is still a controversy regarding its exact etiology, risk factors, diagnostic parameters and required therapy. Considering that acute poisonings are treated in different types of medical institutions this serious complication of organophosphate insecticide (OPI poisoning is frequently overlooked. The aim of this paper was to present a case of IMS in organophosphate poisoning, which, we believe, provides additional data on the use of oxime or atropine. Case report. After a well-resolved cholinergic crisis, the patient developed clinical presentation of IMS within the first 72 h from deliberate malathion ingestion. The signs of IMS were weakness of proximal limb muscles and muscles innervated by motor cranial nerves, followed by the weakness of respiratory muscles and serious respiratory insufficiency. Malathion and its active metabolite were confirmed by analytical procedure (liquid chromatography-mass spectrometry. Pralidoxime methylsulphate, adiministered as a continuous infusion until day 8 (total dose 38.4 g, and atropine until the day 10 (total dose 922 mg did not prevent the development of IMS, hence the mechanical ventilation that was stopped after 27 h had to be continued until the day 10. Conclusion. Continuous pralidoxime methylsulphate infusion with atropine did not prevent the development of IMS, most likely due to the delayed treatment and insufficient oxime dose but also because of chemical structure and lipophilicity of ingested OPI. A prolonged intensive care monitoring and respiratory care are the key management for the intermediate syndrome. [Projekat Ministarstva nauke Republike Srbije, br. OI 176018, No. 46009

Outcomes from the PLATO trial demonstrated that ticagrelor + ASA reduced the rate of a combined endpoint of cardiovascular death, myocardial infarction, or stroke compared to clopidogrel + ASA.ObjectiveThis analysis estimated the budget impact of the use of ticagrelor and clopidogrel for the prevention of thrombotic cardiovascular events in patients with ACS in Italy, based on the PLATO trial results.MethodsA budget-impact model (BIM was developed to estimate the direct costs up to 12 months after an ACS event from the Italian NHS perspective. Resource utilization (drugs, screening, monitoring, hospitalizations and transfusions was derived from the PLATO trial. Only direct medical costs were considered. Ex-factory prices (including all discounts and National Tariffs were used to estimate the costs of drugs and medical resource, respectively. The BIM showed the difference in expenditure and cardiovascular events (myocardial infarction and cardiovascular death – PLATO trial generated by the base case as calculated for current prescription volumes (ticagrelor 50.6%, clopidogrel 49.4%, and for different prescription volume scenarios (ticagrelor at 75% and 100%. Key variables were tested in the sensitivity analysis.ResultsTicagrelor was associated with a medical cost offset driven by fewer hospitalizations; this partly offsets the incremental drug cost and results in an annual incremental cost per patient of €32.53 (€11,526.03 for ticagrelor and €11,493.50 for clopidogrel. Based on data from the PLATO trial, the incidence of ACS and current prescription volumes in Italy, the BIM predicts that the total number of cardiovascular events and costs are 6,169 and €652.3M, respectively.

    To explore the curative effects on surgical methods for the prevention of Frey syndrome and a concave facial deformity after parotidectomy. A literature search was performed using the Wianfang Database, Chinese Biomedical Literature Disk Database, Chinese Digital Hospital Library and Chinese Scientific Journals Database of VIP from January 1989 to December 2008. Twenty-six Chinese language controlled studies involving surgical techniques for prevention of Frey syndrome and the concave facial deformity after parotidectomy were identified. Review manager 4.2 software was applied for Meta analysis. Meta-analysis for surgical techniques to prevent symptomatic Frey syndrome, a positive starch-iodine test, and contour deformity, favored intervention with a cumulative odds ratio (OR) of 0.14 [95% confidence interval (CI), 0.07-0.25]; OR, 0.21 (95% CI, 0.17-0.26); and OR, 0.09 (95% CI, 0.04-0.19), respectively. There was a significant difference in the incidence of these complications between surgical treatment groups and control groups (Z = 6.42, Z = 13.70, Z = 6.43, all P starch-iodine test (Z = 7.48, P starch-iodine test (Z = 5.72, P 0.05). Meta-analysis of operative techniques to prevent symptomatic Frey syndrome, a positive starch-iodine test, and facial asymmetry suggests that such methods are likely to reduce the incidence of these complications and improve the quality of life after parotidectomy.

    Full Text Available Central venous catheters (CVCs are frequently used in neonatal care. The rate of complications upon CVC use is high and the spectrum ranges from catheter tip dislocation to cardiac tamponade and death. Here we present an explanation model to the phenomenon of paravasate into human anatomical cavities based on two illustrative cases: Extremely low birth weight twins suffering from abdominal compartment syndromes due to different pathologies – one with a trans-peritoneal and one with intra-abdominal effusion. In both siblings the peripherally introduced central catheter (PICC perforated the vessel without clinical signs of bleeding and contributed to abdominal and thoracal complications. Case I (23 + 5 gestational week; 770 g; female showed clinical signs of an abdominal compartment syndrome without respective intestinal pathology upon open surgical procedure with ileostomy. Radiographic contrast examination showed retroperitoneal leakage when administered through the catheter. Replacement into the subclavian vein led to cardio-respiratory misbalance due to severe pleural effusion. Re-replacement finally led to clinical restitution after 60 days of intensive care. Case II (23 + 5 gestational week; 690 g; female showed clinical signs of an abdominal compartment syndrome, too. Radiographic contrast examination showed leakage from the PICC into the abdomen. Replacement of the PICC and invasive care led to improvement after 3 days. The 2 cases reveal that the displacement of a PICC can occur without direct clinical signs of hemodynamic imbalance i.e. bleeding or hematoma. Displacement of the catheter tip from intra-vascular, retro-peritoneal position can cause abdominal compartment syndromes either via trans-peritoneal migration of fluids or after perforation of the peritoneum via intra-abdominal administration of given infusion. Both options caused life threatening complications. Watchfulness and intensive surgical and non-surgical care are

    Full Text Available Context-aware monitoring systems designed for e-Health solutions and ambient assisted living (AAL play an important role in today’s personalized health-care services. The majority of these systems are intended for the monitoring of patients’ vital signs by means of bio-sensors. At present, there are very few systems that monitor environmental conditions and air quality in the homes of users. A home’s environmental conditions can have a significant influence on the state of the health of its residents. Monitoring the environment is the key to preventing possible diseases caused by conditions that do not favor health. This paper presents a context-aware system that monitors air quality to prevent a specific health problem at home. The aim of this system is to reduce the incidence of the Sudden Infant Death Syndrome, which is triggered mainly by environmental factors. In the conducted case study, the system monitored the state of the neonate and the quality of air while it was asleep. The designed proposal is characterized by its low cost and non-intrusive nature. The results are promising.

    Frey syndrome (FS) or depressive deformity (DD) occurring after parotidectomy significantly reduces a patient's quality of life. However, there seems to be no effective treatment strategy against these complications. In this study, we report our experience of using platysma muscle flap (PMF) to prevent the development of FS and DD after parotidectomy, and evaluate its effect subjectively and objectively. Superficial parotidectomy was performed for eight cases of parotid gland tumor, and a PMF was transferred to cover the site. The incidence of FS and DD were evaluated subjectively, using a questionnaire to the patients and board-certified reconstructive surgeons, and objectively, using Minor's starch-iodine test. In seven patients, the defect could be completely covered with PMF, and none of them developed FS or obvious DD. However, in one patient, the defect could be only partially covered, and the patient developed complications in the exact site that the flap did not cover. Overall scores from the questionnaire were high in relation to both cosmetic and functional perspectives from most of the patients and all the surgeons. No patients had major postoperative complications requiring revision. PMF can be useful to cover the defect and prevent complications after parotidectomy. PMF is relatively easy to perform with fewer complications; however, a complete coverage of the defect should be ensured to obtain optimal results.

    Treacher Collins syndrome (TCS) is a congenital disorder of craniofacial development arising from mutations in TCOF1, which encodes the nucleolar phosphoprotein Treacle. Haploinsufficiency of Tcof1 perturbs mature ribosome biogenesis, resulting in stabilization of p53 and the cyclin G1-mediated cell-cycle arrest that underpins the specificity of neuroepithelial apoptosis and neural crest cell hypoplasia characteristic of TCS. Here we show that inhibition of p53 prevents cyclin G1-driven apoptotic elimination of neural crest cells while rescuing the craniofacial abnormalities associated with mutations in Tcof1 and extending life span. These improvements, however, occur independently of the effects on ribosome biogenesis; thus suggesting that it is p53-dependent neuroepithelial apoptosis that is the primary mechanism underlying the pathogenesis of TCS. Our work further implies that neuroepithelial and neural crest cells are particularly sensitive to cellular stress during embryogenesis and that suppression of p53 function provides an attractive avenue for possible clinical prevention of TCS craniofacial birth defects and possibly those of other neurocristopathies.

    Neonatal abstinence syndrome (NAS) is a complicated medical condition with treatment regimens that traditionally have included methadone and other opioids, barbiturates, and benzodiazepines. We describe a case series in which clonidine was used for the prevention and management of patients with NAS. Medical records of infants treated with clonidine for NAS from January 2003 to March 2006 were reviewed for gestational age, birth weight, NAS score, dose of clonidine, duration of treatment, and additional medications required. Fourteen patients were identified. The mean gestational age was 30.1 weeks (range 24.4-40.7 weeks); three patients were full-term. Eleven had been on intravenous fentanyl for sedation; three were born to opioid-dependent mothers. All patients were treated with clonidine, administered in doses of 0.5-1.0 mcg/kg orally every 6 h. No patient received opioids. Mean duration of treatment was 6.8 days (range 4-15). Mean abstinence scores were 6.4 pretreatment (range 0-20) and 1.9 posttreatment (range 0-5). No patients suffered an adverse event (hypotension, bradycardia, excessive sedation, and oxygen desaturation) from clonidine administration, and no seizures were identified. Our data suggest that clonidine may be a reasonable alternative to more traditional agents used to prevent or treat NAS. We agree with the statement of the American Academy of Pediatrics Committee on Drugs that states that larger trials and pharmacologic data are needed before the routine use of clonidine can be recommended.

    Women from Lynch syndrome/hereditary nonpolyposis colorectal cancer (Lynch/HNPCC) families have an increased lifetime risk of developing endometrial and ovarian cancer. This study models a comparison of management strategies for women who carry a Lynch/HNPCC mutation. A decision analytic model with three arms was designed to compare annual gynecologic examinations with annual screening (ultrasonography, endometrial biopsy, CA 125) and with hysterectomy with bilateral salpingo-oophorectomy at age 30 years The existing literature was searched for studies on the accuracy of endometrial and ovarian cancer screening using endometrial biopsy, transvaginal ultrasonography, and serum CA 125. The Surveillance, Epidemiology and End Results database from 1988 to 2001 was used to estimate cancer mortality outcomes. In the surgical arm, 0.0056% of women were diagnosed with ovarian cancer and 0.0060% of women with endometrial cancer. These numbers increased to 3.7% and 18.4% in women being screened, and 8.3% and 48.7% in women undergoing annual examinations, respectively. Surgical management led to the longest expected survival time at 79.98 years, followed by screening at 79.31 years, and annual examinations at 77.41 years. If starting at age 30 and discounting life years at 3%, surgery still leads to the greatest expected life years. When comparing prophylactic surgery with the screening option, one would need to perform 75 surgeries to save one woman's entire life. For cancer prevention, however, only 28 and 6 prophylactic surgeries would need to be performed to prevent one case of ovarian and endometrial cancer, respectively. Risk-reducing hysterectomy and bilateral salpingo-oophorectomy may be considered in women with Lynch/HNPCC to prevent gynecologic cancers and their associated morbidities.

    Postpericardiotomy syndrome, postoperative atrial fibrillation (AF), and postoperative effusions may be responsible for increased morbidity and health care costs after cardiac surgery. Postoperative use of colchicine prevented these complications in a single trial. To determine the efficacy and safety of perioperative use of oral colchicine in reducing postpericardiotomy syndrome, postoperative AF, and postoperative pericardial or pleural effusions. Investigator-initiated, double-blind, placebo-controlled, randomized clinical trial among 360 consecutive candidates for cardiac surgery enrolled in 11 Italian centers between March 2012 and March 2014. At enrollment, mean age of the trial participants was 67.5 years (SD, 10.6 years), 69% were men, and 36% had planned valvular surgery. Main exclusion criteria were absence of sinus rhythm at enrollment, cardiac transplantation, and contraindications to colchicine. Patients were randomized to receive placebo (n=180) or colchicine (0.5 mg twice daily in patients ≥70 kg or 0.5 mg once daily in patients <70 kg; n=180) starting between 48 and 72 hours before surgery and continued for 1 month after surgery. Occurrence of postpericardiotomy syndrome within 3 months; main secondary study end points were postoperative AF and pericardial or pleural effusion. The primary end point of postpericardiotomy syndrome occurred in 35 patients (19.4%) assigned to colchicine and in 53 (29.4%) assigned to placebo (absolute difference, 10.0%; 95% CI, 1.1%-18.7%; number needed to treat = 10). There were no significant differences between the colchicine and placebo groups for the secondary end points of postoperative AF (colchicine, 61 patients [33.9%]; placebo, 75 patients [41.7%]; absolute difference, 7.8%; 95% CI, -2.2% to 17.6%) or postoperative pericardial/pleural effusion (colchicine, 103 patients [57.2%]; placebo, 106 patients [58.9%]; absolute difference, 1.7%; 95% CI, -8.5% to 11.7%), although there was a reduction in

    Infection, neoplastic involvement, and hemorrhage, are the most frequent pathologies that involve the ilio-psoas compartment. The extension from contiguous pathological structures and particularly digestive and urological organs, are often the origin of abscess formation or malignant tumours. The radiological findings including ultrasonography, CT, and magnetic resonance imaging, show a low specificity, which improves if the clinical history is known. The final diagnosis is confirmed by puncture or biopsy. (author)

    This report describes and interactive program RADIO (Radioactive Decay Information Online) for studying the radioactive decay process, with applications to many ecological problems, but not necessarily involving radioactive processes. Starting with the compartment coefficients and initial values of the various compartments the problem is solved as a system of linear ordinary differential equations. The method of solution is the direct use of matrix exponentials or the backward differences method. A program INVERS is also available for the solution of the inverse problem, that is parameter estimation in a system of linear ordinary differential equations when the solution is available pointwise. The output can be printed on a line printer either from a result file or from the plot file, which of course also can be used to produce graphic output. The plot file is processed by the plotting program VISION or by the auxiliary printing program RADAR. Another file can be used for a later restart from the point of time where the previous computation was aborted or from an arbitrary point of time if the relevant starting information is available. This is useful in order to avoid the manual input of a compartment matrix if it is similar to one used before. When the program RADIO is run the user answers to the question asked by the program. The programs are written in Fortran 77 for the Digital Equipment VAX 11 with graphical presentation on a Tektronix 4010, and are available from the author. (Author)

    Control of rubella is desired because infection in early pregnancy can result in miscarriage, foetal death or congenital abnormality. Primary studies examining the effectiveness of immunoglobulins for post-exposure prophylaxis of rubella have small sample sizes and varying results. National public health recommendations suggest a degree of effectiveness. To assess the effectiveness of intramuscular injection or intravenous infusion of polyclonal immunoglobulins of human sera or plasma origin for preventing rubella and congenital rubella syndrome when administered to exposed susceptible people before the onset of disease. We searched CENTRAL (2014, Issue 7), MEDLINE (1946 to August week 2, 2014), EMBASE (1974 to August 2014), CINAHL (1981 to August 2014), LILACS (1982 to August 2014) and Web of Science (1955 to August 2014). We searched ClinicalTrials.gov and the World Health Organization International Clinical Trials Registry on 16 October 2014. We searched the reference lists of relevant retrieved reviews and studies and identified national public health guidelines. For the outcome 'preventing cases of rubella', we included randomised controlled trials (RCTs) and quasi-RCTs. We found several studies addressing this outcome where the design was a controlled clinical trial (CCT) (with exposure to rubella virus controlled by the investigators) but the method of allocation of participants to groups was not reported. We found an alternative report of one of these studies that indicated participants were assigned to groups randomly. We therefore included such studies as meeting criteria for RCTs or quasi-RCTs and undertook sensitivity analyses. For the outcomes, 'congenital rubella infection' and 'congenital rubella syndrome', we included RCTs, quasi-RCTs and prospective controlled (cohort) studies. Participants were necessarily susceptible and exposed to rubella. Polyclonal immunoglobulins derived from human sera or plasma must have been administered intramuscularly or

    Full Text Available Ovarian hyperstimulation syndrome (OHSS is a relatively common complication of ovarian stimulation and can be life threatening. The pathophysiology of OHSS is characterized by increased capillary permeability, leading to leakage of fluid from the vascular compartment, with third-space fluid accumulation and intravascular dehydration. The increased intra-abdominal pressure indicated that OHSS may be considered a compartment syndrome. Vascular endothelial growth factor, also known as vascular permeability factor, has emerged as one of the mediators intrinsic to the development of OHSS. Conventional management is focused on supportive care until the spontaneous resolution of the condition. The standard of care for treatment—monitoring of appropriate clinical parameters, fluid balance management, thrombosis prophylaxis, and ascites treatment—should prevent severe morbidity in most cases. This review will cover inpatient and outpatient management. The potential therapeutic approach targeting the vascular endothelial growth factor system will be discussed.

    Objective Postpericardiotomy syndrome (PPS), which is thought to be related to autoimmune phenomena, represents a common postoperative complication in cardiac surgery. Late pericardial effusions after cardiac surgery are usually related to PPS and can progress to cardiac tamponade. Preventive measures can reduce postoperative morbidity and mortality related to PPS. In a previous study, diclofenac was suggested to ameliorate autoimmune diseases. The aim of this study was to determine whether postoperative use of diclofenac is effective in preventing early PPS after cardiac surgery. Methods A total of 100 patients who were administered oral diclofenac for postoperative analgesia after cardiac surgery and until hospital discharge were included in this retrospective study. As well, 100 patients undergoing cardiac surgery who were not administered nonsteroidal anti-inflammatory drugs were included as the control group. The existence and severity of pericardial effusion were determined by echocardiography. The existence and severity of pleural effusion were determined by chest X-ray. Results PPS incidence was significantly lower in patients who received diclofenac (20% vs 43%) (Pdiclofenac had a significantly lower incidence of pericardial effusion (15% vs 30%) (P=0.01). Although not statistically significant, pericardial and pleural effusion was more severe in the control group than in the diclofenac group. The mean duration of diclofenac treatment was 5.11±0.47 days in patients with PPS and 5.27±0.61 days in patients who did not have PPS (P=0.07). Logistic regression analysis demonstrated that diclofenac administration (odds ratio [OR] 0.34, 95% confidence interval [CI] 0.18–0.65, P=0.001) was independently associated with PPS occurrence. Conclusion Postoperative administration of diclofenac may have a protective role against the development of PPS after cardiac surgery. PMID:26170687

    Metabolic Syndrome (MetSyn) is one of the strongest predictors of type 2 diabetes (DM2) and cardiovascular disease (CVD). It is associated with a 4- to 10-fold increased risk of DM2 and a 2- to 3-fold increased risk of CVD. Low income and minority women have some of the highest rates of MetSyn. This study examines the effect of a unique, community based, primary prevention program on the rates of MetSyn and health habits. Sixty-four low income and minority women were enrolled in the HAPPY (Health Awareness and Primary Prevention in Your neighborhood) Heart Program in an eastern suburb of Boston. Over these 2 years, patients were evaluated by an interdisciplinary medical team: their primary physician, cardiologist, nutritionist, physical therapist, and health coach. The rate of MetSyn was measured at baseline, year 1, and year 2. Comparisons were made either using the paired t test for normally distributed variables or the Wilcoxon Sign test for non-normal variables. The rate of MetSyn fell from 64.7% at baseline to 34.9% at year 1 (p=0.01) and 28.2% at year 2 (p<0.001). This was driven by increases in high-density lipoprotein (HDL-C) (p<0.001) and decreases in blood pressure (p=0.05). Fasting blood glucose trended down, but the hemoglobin A1c (HbA1c) reached significance (decreasing from 6 to 5.8, p<0.01). Nutrition and exercise habits trended toward improvement. There were significant decreases in anxiety (p<0.001), depression (p=0.006) and stress (p=0.002). This lifestyle intervention program is effective at decreasing MetSyn in a socioeconomically disadvantaged, largely minority, female population. This program also decreases anxiety, stress, and depression among participants.

    The acute respiratory distress syndrome (ARDS) is typically manifested by refractory hypoxemia with high mortality. A correct diagnosis is the first step to achieve better outcomes. An early intervention to manage modifiable risk factors of ARDS development and the avoidance of aggravating factors that increase disease severity and progression should be carefully addressed. A management plan is necessary at an early stage of ARDS to determine the level of intensive care. It should be carefully decided which therapeutic measures should be performed depending on the patient׳s underlying clinical condition. The clinician׳s considerate prudence is required in decisions of when to apply intensive measures for an ARDS treatment. Mechanical ventilator support should be carefully used depending on the patient׳s severity and pathological phase. Decreasing inappropriate alveolar strain through a low tidal volume under optimal positive end-expiratory pressure is key for ventilator support in ARDS. The extracorporeal membrane oxygenation applied in the experienced centers seems to improve the survival of patients with severe ARDS. A constellation of physical and psychological problems can develop or persist for up to 5 years in patients with ARDS. Therefore, an early mobilization with rehabilitation, even during an intensive care unit stay, should be seriously considered whenever feasible. Lastly, prevention of aspiration, stress ulcers, deep vein thrombosis, catheter-related infection, overhydration, and heavy sedation is essential to achieve better outcomes in ARDS.

    Full Text Available The translation of the growing increase of findings emerging from basic nutritional science into meaningful and clinically relevant dietary advices represents nowadays one of the main challenges of clinical nutrition. From nutrigenomics to deep phenotyping, many factors need to be taken into account in designing personalized and unbiased nutritional solutions for individuals or population sub-groups. Likewise, a concerted effort among basic, clinical scientists and health professionals will be needed to establish a comprehensive framework allowing the implementation of these new findings at the population level. In a world characterized by an overwhelming increase in the prevalence of obesity and associated metabolic disturbances, such as type 2 diabetes and cardiovascular diseases, tailored nutrition prescription represents a promising approach for both the prevention and management of metabolic syndrome. This review aims to discuss recent works in the field of precision nutrition analyzing most relevant aspects affecting an individual response to lifestyle/nutritional interventions. Latest advances in the analysis and monitoring of dietary habits, food behaviors, physical activity/exercise and deep phenotyping will be discussed, as well as the relevance of novel applications of nutrigenomics, metabolomics and microbiota profiling. Recent findings in the development of precision nutrition are highlighted. Finally, results from published studies providing examples of new avenues to successfully implement innovative precision nutrition approaches will be reviewed.

    An alcohol-server training program to prevent fetal alcohol syndrome was developed, implemented, and evaluated in a comparison study of public drinking establishments in New Mexico and Oregon. The management and serving staffs of 148 establishments licensed for on-premise alcohol sales in the two states studied were trained to discourage alcohol consumption by pregnant customers. Pre- and post-tests of server responses to pregnant-appearing "pseudo-patron" actors ordering alcohol in experimental (n = 148) and comparison (n = 183) establishments were a key method of evaluating the efficacy of this intervention. Within-group chi-square analyses compared rates of service refusal at baseline with 1-month, 6-month, and 12-month follow-up points for both the trained (experimental) and the comparison establishments. No differences were found between experimental and comparison establishments at baseline at either site, but significant differences were found for New Mexico at each posttraining measurement point. In Oregon, the refusal rate at baseline increased from 1.5% at baseline to 8.3% at 1 month, which only approached significance. In New Mexico, at baseline the refusal rate was 8.6%, and it rose to 39.2% at 6 months (p Mexico establishments.

    Passage of fetal bowel movement (meconium) is common (in about one out of six births), and in some the staining of the amniotic fluid is a sign of fetal distress. Inhalation of meconium (aspiration syndrome, in upto one out of five to eight such births) just before or at birth may be preventable by a coordinated approach by well-trained and informed birth attendants. Respiratory failure secondary to meconium aspiration syndrome (MAS) remains a major cause of morbidity and mortality in the neonatal population. Infants with hypoxemic respiratory failure because of MAS, persistent pulmonary hypertension of the newborn and pneumonia/sepsis have an increased survival with extracorporeal membrane oxygenation (ECMO). Other treatment options earlier limited to inotropic support, continuous airway pressure (CPAP), conventional ventilatory management, respiratory alkalosis, paralysis and intravenous vasodilators have been replaced by synchronized intermittent mandatory ventilation (SIMV), high-frequency oscillatory ventilation (HFOV), surfactant and inhaled nitric oxide (iNO). HFOV has been advocated for use to improve lung inflation while potentially decreasing lung injury through volutrauma. Other reports describe the enhanced efficacy of HFOV when combined with iNO. Subsequent to studies reporting that surfactant deficiency or inactivation may contribute to neonatal respiratory failure, exogenous surfactant therapy has been implemented with apparent success. Recent studies have shown that iNO therapy in the neonate with hypoxemic respiratory failure can result in improved oxygenation and decreased need for ECMO. However, these innovative interventions are costly, require a sophisticated infrastructure and are not universally accessible. In this paper, a context of systems-approach for prenatal, natal and postnatal management of babies delivered through meconium stained amniotic fluid (MSAF) so that adverse outcomes are minimized and the least number of babies require

  8. Dietary Exercise as a Novel Strategy for the Prevention and Treatment of Metabolic Syndrome: Effects on Skeletal Muscle Function

    Full Text Available A sedentary lifestyle can cause metabolic syndrome to develop. Metabolic syndrome is associated with metabolic function in the skeletal muscle, a major consumer of nutrients. Dietary exercise, along with an adequate diet, is reported to be one of the major preventive therapies for metabolic syndrome; exercise improves the metabolic capacity of muscles and prevents the loss of muscle mass. Epidemiological studies have shown that physical activity reduces the risk of various common diseases such as cardiovascular disease, diabetes, and cancer; it also helps in reducing visceral adipose tissue. In addition, laboratory studies have demonstrated the mechanisms underlying the benefits of single-bout and regular exercise. Exercise regulates the expression/activity of proteins associated with metabolic and anabolic signaling in muscle, leading to a change in phenotype. The extent of these changes depends on the intensity, the duration, and the frequency of the exercise. The effect of exercise is also partly due to a decrease in inflammation, which has been shown to be closely related to the development of various diseases. Furthermore, it has been suggested that several phytochemicals contained in natural foods can improve nutrient metabolism and prevent protein degradation in the muscle.

    Full Text Available Objective:The idiopathic long Q-T syndrome is an infrequently occurring disorder in which affected individuals have an unusual electrocardiographic repolarization abnormality presenting as syncope or loss of consciousness related to ventricular tachycardia or fibrillation. Congenital long Q-T prolongation can be associated with congenital deafness in an autosomal recessive manner (Jervell and Lange-Nielsen syndrome. The purpose of this stuff was to screen this electrocardiographic abnormality in deaf-mute school children in our population, which has not been yet performed. Materials & Methods:  Of 1190 patients with hearing loss, 779 had congenital sensorineural deafness (CSD, aged 13±3.8 years (4-24, 63% female and 37% male. The family history of deafness was as follows: Cardiac axis deviation was found in 56 (7% patients. Electrical conduction abnormalities were found in 12 (15% patients, Wolff-Parkinson-White syndrome, sinus bradycardia, and sinus arrhythmia were found in 2 (0.25%, 4 (0.5%, and 3 (0.38% patients, respectively. The Q-T interval, and Q-Tc duration were 312.6±28.9 ms (200-500 ms, median 320 ms, and 383.6±29.3 ms (232-527 ms, median 413ms, respectively. Long Q-T syndrome was found in 4 (0.5% patients (3F and 1M. Results: Two of these 4 patients had total deafness and 2 had profound hearing loss. None of the patients with mild deafness had Q-T prolongation. Only one of these patients was symptomatic, and had been treated as a case of epilepsy for several years. Conclusion: This data supports the presence of long Q-T syndrome in patients with sensorineural hearing loss in our population, so routine electrocardiographic screening of anyone with congenital deafness is warranted to prevent subsequent associated cardiac arrhythmias and sudden cardiac death.

    Hand-foot syndrome (HFS) is common and frequently occurs in the first cycle of treatment in approximately 40% to 50% of patients who receive capecitabine. Turmeric (Curcuma longa) is a plant used in Ayurvedic medicine with clinical activity in various inflammatory conditions. Our objective was to evaluate whether turmeric was active for the prevention of capecitabine-induced HFS. We included patients older than 18 years of age without previous exposure to capecitabine who were scheduled to receive this medication. Before starting treatment, after three weeks and at the end of six weeks, we evaluated dermatologic toxicity, conducted quality-of-life questionnaires (EORTC-QLQC30 and DLQI) and collected serum inflammatory biomarkers (inerleukin-6 (IL-6), tumor necrosis factor-a (TNF-a), C-reactive protein (CRP), and albumin). We administered turmeric at a dose of 4 g/day (2 pills 12 hours apart) starting at the beginning of capecitabine treatment and lasting six weeks. We included 40 patients whose mean age was 62 years. Most were female (80%), 52% had breast cancer, and 47.5% had GI tumors. After the first cycle of capecitabine treatment, we observed that 11 of 40 patients developed HFS (27.5%; 95% CI [15, 42]), whereas four patients developed HFS equal or superior to grade 2 (10%; 95% CI [3.3, 23]). We did not find any correlations between the inflammatory markers tested and HFS. We show that turmeric combined with capecitabine seems to produce a lower rate of HFS, especially grade 2 or higher. These findings need to be reproduced in larger controlled studies.

    Full Text Available Type 2 receptors for vascular endothelial growth factor are believed to be involved in the pathophysiology of ovarian hyperstimulation syndrome (OHSS. The objective of this study was to examine the preventive effects of cabergoline on OHSS and its complications. The study is a non randomized clinical trial conducted in 2006-2008 on 75 patients, which were at risk of OHSS and underwent assisted reproductive techniques. The diagnosis and severity of OHSS were determined using standard criteria. The study included an intervention and a control group. The intervention group comprised of 50 women at risk of OHSS, who were treated with cabergoline (1 mg every other day for 8 days commencing from the day of ovum pick up. The control group comprised of 25 historical cases, which were similar to the case group. The latter group did not receive cabergoline, and their OHSS, if occurred, were managed conservatively after hospital admission. The rates of OHSS, baseline characteristics, ovarian stimulation parameters, and pregnancy occurrence were compared. There was no significant difference between baseline characteristics or ovarian stimulation parameters form the two groups. The incidence of OHSS in the cabergoline-treated group, was significantly (P=0.01 lower than that in the control group (12% vs 36%. Embryo freezing was significantly (P=0.001 lower in the control group, but cycle cancellation was significantly (0.03 lower in the cabergoline group. The findings of the study indicate that cabergoline reduces the incidence of OHSS, and is not associated with adverse effects on pregnancy

    A haemostatic technique that maintains radial artery flow ("patent haemostasis") following transradial catheterization reduces rates of radial artery occlusion (RAO) in patients with stable coronary disease. It is unclear whether this benefit extends to patients with an acute coronary syndrome (ACS). Patients undergoing inpatient transradial catheterization for an ACS were prospectively enrolled in a consecutive cohort study (n=300). Radial haemostasis was obtained using standard radial compression (cohort 1; n=150) or patent haemostasis (cohort 2; n=150). An end-of-case activated clotting time (ACT) was recorded and radial artery patency assessed within 24 hours of sheath removal by reverse Barbeau's test. The incidence of RAO was 16.0% following standard radial compression and 5.3% following patent haemostasis (p=0.003). Univariate predictors of RAO were patent haemostasis (OR 0.30; [0.13-0.68], p=0.004), hyperlipidaemia (OR 0.46; [0.21-0.98], p=0.04), history of current smoking (OR 2.86; [1.3-6.0], p=0.015) and longer procedure times (OR 1.03/additional minute; [1.01-1.05], p=0.003). There was no association between the end-of-case ACT and RAO (OR 1.00; [0.9-1.01] p=1.00). After adjusting for covariates, patent haemostasis reduced the risk of RAO by 70% compared to standard compression (OR 0.30; [0.12-0.77], p=0.12). The c-statistic for model discrimination was 0.79 (95% CI [0.71-0.86], ppatent haemostasis as an independent predictor of reduced RAO (OR 0.38 [0.15-0.95], p=0.039). Patent haemostasis is highly effective in preventing early RAO in patients with ACS. Copyright © 2017 Elsevier B.V. All rights reserved.

    Stevens-Johnson syndrome and toxic epidermal necrolysis are severe mucocutaneous adverse drug reactions characterized by extensive epidermal detachment. The mortality rates have been reported to vary between 1% and 5% for Stevens-Johnson syndrome and 25% and 35% for patients with toxic epidermal necrolysis. Studies have shown that early recognition and prompt withdrawal of the causative agent leads to increased patient survival. A retrospective chart review was conducted on 64 patients admitted to Vancouver General Hospital with a diagnosis of Stevens-Johnson syndrome or toxic epidermal necrolysis from 2001 to 2011. The aim of this study was to identify the medications most often implicated in triggering Stevens-Johnson syndrome and toxic epidermal necrolysis, as well as to delineate the timeline of identification and removal of these triggers. A trigger was identified in 75% of cases. Allopurinol was the single most common offending agent (20% of cases). Anticonvulsants and antibiotics were common triggers. The offending agent was often removed at time of hospital admission/diagnosis but not at onset of symptoms. A history of prior culprit drug exposure with previous mucocutaneous adverse reaction was noted in 19% of cases with identified triggers. Asians and Native North Americans had a higher mortality than whites, and Asians more frequently had allopurinol as a trigger. The onset and high mortality rate of Stevens-Johnson syndrome/toxic epidermal necrolysis may be related to unawareness of the early signs and symptoms of Stevens-Johnson syndrome and toxic epidermal necrolysis, the common drug triggers that cause it, and what investigations (human leukocyte antigen typing in Asians) can be done to prevent it.

    Prior research has shown that unhealthy lifestyles increase the risk for developing a number of chronic diseases, but there are few studies examining how lifestyle changes impact metabolic syndrome. This study analyzed the association between two-year changes in key lifestyle risk metrics and incident metabolic syndrome in adults. A retrospective cohort study was conducted using data from metabolic syndrome free adults in the Heart of New Ulm Project (New Ulm, MN). The outcome was incident metabolic syndrome observed two years after baseline in 2009. The primary predictor was change in optimal lifestyle score based on four behavioral risk factors, including smoking, alcohol use, fruit/vegetable consumption, and physical activity. In the analytical sample of 1059 adults, 12% developed metabolic syndrome by 2011. Multivariable regression models (adjusted for baseline lifestyle score, age, sex, education, cardiovascular disease, and diabetes) revealed that a two-year decrease in optimal lifestyle score was associated with significantly greater odds of incident metabolic syndrome (OR = 2.92; 95% CI: 1.69, 5.04; p metabolic syndrome over the two-year study timeframe.

    Full Text Available The paper deals with a rare monogenic connective tissue disease from a group of fibrillinopathies with autosomal dominant inheritance — Beals syndrome caused by a mutation in the FBN2 gene. Attention is drawn to the high phenotypic similarity of this disease and Marfan syndrome (FBN1 gene mutation, which is associated with the almost complete identity of two proteins: fibrillin 1 and fibrillin 2.The paper describes a clinical case of a child with Beals syndrome and the typical manifestations of the disease: asthenic constitution, arachnodactyly of the hands and feet, congenital contractures of the large and small joints, chest deformity, kyphoscoliosis, talpes, and crushed ears. The investigators made a differential diagnosis with other connective tissue diseases, such as Marfan syndrome, Stickler syndrome, Ehlers–Danlos syndrome, homocystenuria, and arthrogryposis. DNA diagnosis verified the Beals syndrome in the proband. Exon 28 in the FBN2 gene showed the previously undescribed missense mutation of c.3719G>A, resulting in the amino acid substitution of cysteine for tyrosine (p.Cys1240Tyr in the structure of the protein fibrillin 2. A de novo mutation occurred. There is evidence for its pathogenicity in the development of the clinical symptoms of the disease. The problems of effective medical genetic counseling in this family are discussed.

    Autopsy studies suggest that Wernicke-Korsakoff syndrome (WKS) is not a rare disorder, particularly in individuals who abuse alcohol. Thiamine has been established as the treatment of choice for over 50 years, but uncertainty remains about appropriate dosage and duration. Current practice guidelines are based on case reports and clinical experience. This is an update of a review first published in 2004 and last updated in 2008. • To assess the efficacy of thiamine in preventing and treating the manifestations of WKS due to excess alcohol consumption. • To determine the optimum form, dose and duration of thiamine treatment for this indication. ALOIS, the Specialized Register of the Cochrane Dementia and Cognitive Improvement Group (CDCIG), The Cochrane Library, MEDLINE, EMBASE, PsycINFO, CINAHL and LILACS were searched on 6 September 2012 using the term thiamine OR aneurine. ALOIS contains records from all major health care databases (The Cochrane Library, MEDLINE, EMBASE, PsycINFO, CINAHL, LILACS) as well as from many trial databases and grey literature sources. Any randomised trials comparing thiamine with alternative interventions or comparing different thiamine regimens (varying in formulation, dose or duration of administration). All abstracts were independently inspected by two reviewers (ED and PWB), and relevant articles were retrieved and assessed for methodological quality using criteria provided in the Cochrane Handbook for Systematic Reviews of Interventions. Two studies were identified that met the inclusion criteria, but only one contained sufficient data for quantitative analysis. Ambrose (2001) randomly assigned participants (n = 107) to one of five doses of intramuscular thiamine and measured outcomes after 2 days of treatment. We compared the lowest dose (5 mg/day) with each of the other four doses. A significant difference favoured 200 mg/day compared with the 5-mg/day dose in determining the number of trials needed to meet inclusion criteria

    2002-01-01

    Aim: The sensitivity and specificity of rest/stress (R/S) myocardial perfusion imaging (MPI) in detecting an acute ischemic coronary syndrome (AICS) was determined in 100 consecutive patients (pts) admitted to the Chest Pain Clinic-Observation Unit (CPC-OU) with chest pain (CP) of suspected cardiac etiology and a negative (neg) or non diagnostic (dx) EKG. There were 57 females and 43 males, 30-83 years of age. 50 studies were performed from 1/15/98 to 4/2/98; 50 from 11/19/99 to 1/10/00. Material and Methods: An AICS was deemed present if a reversible perfusion defect was demonstrated scintigraphically; a ?50% luminal narrow angiographically. No AICS if the pt had a normal R/S MPI, a fixed defect with normal wall motion and thickening, a neg cardiac catheterization, or was free of cardiac symptoms and had no history of a vascular event for 2-3 years post CPC-OU admission. 13 pts with a positive MPI had a cardiac catheterization, none with a neg MPI. SPECT rest MPI's were performed 30-90 minutes (mins) post 10.0 mCi of technetium 99m Sestamibi. SPECT stress MPI's were performed following a 6-8 hour acute myocardial infarction enzyme (CP-MB/Troponin 1) rule out and 30-90 mins post 30.0 mCi of technetium 99m Sestamibi. Results: 29 pts were lost to follow-up. There were 12 true positive, 5 false positive, 54 true negative and 0 false negative studies. The sensitivity, specificity, positive and negative predictive value of a R/S MPI in detecting an AICS is 100%, 91%, 70% and 100%, respectively. An AICS was detected in 12% of pts admitted to the CPC-OU; a finding that correlates with its reported incidence of 2-12%. 6 were managed medically, 3 required emergent bypass surgery, 3 were stented. Conclusion: R/S MPI should be included in the CPC-OU dx work-up of pts with CP of suspected cardiac etiology to prevent missed AICS diagnoses. Patient care will be optimized and health care and medical malpractice awards for failure to diagnosis an acute myocardial infarction

    The metabolic syndrome is a cluster of cardiovascular risk factors and its prevalence is alarmingly high in Kuwait, affecting nearly one third of the adult population. There is lack of information about the role of community pharmacists in the care of patients with the metabolic syndrome. To assess the awareness and opinions of community pharmacists about the metabolic syndrome and identify the services they provide for identification, management and monitoring of patients with the metabolic syndrome. Community pharmacies in Kuwait. A descriptive, cross-sectional study was performed on a randomly selected sample of 225 community pharmacists. Data were collected via face-to-face structured interview of the pharmacists using a pre-tested questionnaire. Pharmacists' knowledge and views on the metabolic syndrome, monitoring services provided, self-reported practices and perceived effectiveness of the various management interventions for the metabolic syndrome. The response rate was 97.8 %. Nine pharmacists claimed to know about the metabolic syndrome, but only one pharmacist could identify the condition correctly. After being given a definition of the metabolic syndrome, 67.7 % of respondents strongly agreed that its prevalence was rising in Kuwait. Nearly two thirds of respondents reported providing height and weight measurement service while 82.7 and 59.5 % of pharmacies provided blood pressure and blood glucose measurements, respectively. Waist circumference and lipid profile measurements were the least provided services (1.8 %). Respondents claimed to be involved in counseling patients on lifestyle modifications including increased exercise (98.1 %) and weight reduction through diet (96.9 %). Most pharmacists were involved in encouraging patients' adherence with prescribed treatments (98.6 %) and perceived these as the most effective intervention for the management of the metabolic syndrome (95.0 %). Respondents were less involved in monitoring patients' response

    Respiratory distress syndrome (RDS) is caused by a deficiency of pulmonary surfactant (an active agent that keeps pulmonary alveoli open and facilitates the entry of air to the lungs, thus improving the oxygenation of the newborn).A number of interventions such as pulmonary surfactant and prenatal corticosteroids are used to prevent RDS. Ambroxol has been studied as a potential agent to prevent RDS, but effectiveness and safety has yet to be evaluated. To evaluate the efficacy and safety of giving ambroxol to pregnant women who are at risk of preterm birth, for preventing neonatal RDS. We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (29 November 2013), CENTRAL (The Cochrane Library 2013, Issue 11),Embase (1988 to November 2013), MEDLINE (PubMed 1970 to November 2013), LILACS (1982 to November 2013), the WHO International Clinical Trials Registry Platform (ICTRP) (November 2013) and reference lists of retrieved studies. Randomised controlled trials (RCTs) comparing the administration of ambroxol given to pregnant women at risk of preterm birth versus placebo, antenatal corticosteroids (betamethasone or dexamethasone), or no treatment.We did not identify any trials comparing ambroxol with dexamethasone (corticosteroid) in this review. Nor did we identify any trials comparing ambroxol combined with corticosteroid versus corticosteroid alone, or placebo/no treatment. Two review authors independently assessed trials for inclusion and trial quality. Two review authors independently extracted data. Data were checked for accuracy. We included 14 studies (in 18 trial reports), involving 1047 pregnant women at risk of preterm birth with 1077 newborns.

    As the Compartmented Mode Workstation (CMW) market has matured, several vendors have released new versions of their CMW operating systems. These include a new version from SecureWare (CMW + Version 2.4), and Sun`s CMW 1.1 (also known as Trusted Solaris 1.1). EC is now shipping MLS+ 3.0 for DEC Alpha platforms. Relatively new entries in the market include Loral B1/CMW for IBM RS/6000 platforms and a SecureWare-based CMW for HP platforms (HP-UX 10.09). With all these choices it is time for a comparative analysis of the features offered by the various vendors. The authors have three of the above five CMW systems plus HP-UX BLS 9.09, which is a multilevel secure operating system (OS) targeted at the B1 level but not a CMW. Each is unique in sometimes obvious, sometimes subtle ways, a situation that requires knowing and keeping straight a variety of commands to do the same thing on each system. Some vendors offer extensive GUI tools for system administration; some require entering command-line commands for certain system administration tasks. They examine the differences in system installation, system administration, and system operating among the systems. They look at trusted networking among the various systems and differences in the network databases and label encodings files. They examine the user interface on the various systems from logging in to logging out.

    To assess the evolving global epidemiology of mushroom poisoning and to identify new and emerging mushroom poisonings and their treatments, a descriptive analysis and review of the world's salient scientific literature on mushroom poisoning was conducted. Data sources from observation studies conducted over the period 1959-2002 and describing 28,018 mushroom poisonings since 1951 were collected from case reports, case series, regional descriptive studies, meta-analyses, and laboratory studies of mushroom poisonings and the toxicokinetics of mycotoxins. Studies included in the review were selected by a MEDLINE search, 1966-2004, an Ovid OLDMEDLINE search, 1951-1965, and a medical library search for sources published before 1951. To better guide clinicians in establishing diagnoses and implementing therapies, despite confusing ingestion histories, data were extracted to permit an expanded syndromic classification of mushroom poisoning based on presentation timing and target organ systemic toxicity. The final 14 major syndromes of mushroom poisoning were stratified first by presentation timing and then by target organ systemic toxicity and included early (syndromes (> or =1 day). There were eight early syndromes (four neurotoxic, two gastrointestinal, two allergic); three late syndromes (hepatotoxic, accelerated nephrotoxic, erythromelalgia); and three delayed syndromes (delayed nephrotoxic, delayed neurotoxic, rhabdomyolysis). Four new mushroom poisoning syndromes were classified including accelerated nephrotoxicity (Amanita proxima, Amanita smithiana), rhabdomyolysis (Tricholoma equestre, Russula subnigricans), erythromelalgia (Clitocybe amoenolens, Clitocybe acromelalgia), and delayed neurotoxicity (Hapalopilus rutilans). In addition, data sources were stratified by three chronological time periods with >1,000 confirmed mushroom ingestions reported and tested for any statistically significant secular trends in case fatalities from mushroom ingestions over the

    Full Text Available Rubella is a viral disease with minor morbidity and few complications unless it is contracted by a pregnant woman. Rubella infection during the first trimester of pregnancy often leads to fetal death or severe congenital defects (congenital rubella syndrome, CRS. Rubella remains endemic in many countries of Latin America and the Caribbean. It has been estimated that 20000 or more infants are perhaps born with CRS each year in Latin American and Caribbean countries. While the inclusion of rubella vaccination into routine childhood immunization will decrease rubella virus circulation among young children, it will not have immediate impact on the transmission of rubella among adults or the occurrence of CRS. A one-time mass campaign targeting both males and females 5 to 39 years of age with measles-mumps-rubella or measles-rubella vaccine followed by the use of measles-mumps-rubella vaccine in routine early childhood vaccination will prevent and control both rubella and CRS promptly. In April 1988, the Ministers of Health of the English-speaking Caribbean targeted rubella for elimination by the end of the year 2000 using the vaccination strategy outlined above. The rubella elimination experience of these countries will provide useful information for the eventual elimination of rubella virus from the Americas.La rubéola es una enfermedad vírica que produce poca morbilidad y pocas complicaciones, a no ser que la contraiga una mujer embarazada.

    Type 2 diabetes is a chronic disease associated with significant morbidity and mortality that is increasing in prevalence worldwide. Although our current methods for treating type 2 diabetes and its complications have improved, prevention of the disease is preferable, Epidemiologic data suggest that most cases of type 2 diabetes could be attributed to habits and forms of modifiable behavior. Recent evidence from randomized controlled trials has confirmed that lifestyle plays a central role in diabetes prevention. However, the optimal prevention strategy remains to be determined. This review presents the evidence for dietary components that may modify diabetes risk and suggests nutritional interventions that may be of benefit in preventing the disease.

    2015-01-01

    Full Text Available Background: Excessive physical exercises (overtraining can increase the production of reactive oxygen species (ROS. One of the indicators of overtraining syndrome is a decrease in insulin-like growth factor binding protein 3 (IGFBP-3. Administration of Hibiscus sabdariffa Linn., a powerful antioxidant, is expected to boost endogenous antioxidants, and thus prevents overtraining. The aim of this study is to determine the effect of H. sabdariffa on IGFBP-3 levels in rats under ”overtraining physical excersice”.Methods: This experimental study was conducted on 30 male rats (Rattus norvegicus 200-250 grams, randomly allocated into 5 groups: 1 control group (C; 2 control with H. sabdariffa (C-Hib; 3 mild aerobic exercise (A-Ex; 4 overtraining exercise (OT; 5 overtraining exercise with H. Sabdariffa (OT-Hib. H. sabdariffa (400 mg/kg/d, 11 weeks were administered orally via syringe cannula. IGFBP-3 was measured by using ELISA (Cusa bio kit and data were analyzed with ANOVA test.Results: Plasma level of IGFBP-3 in the C and OT groups were 17.4 ± 10 mIU/L, the lowest in OT groups (10.7 ± 9.9 mIU/L and the OT-Hib group had the highest level (31.5 ± 6.2 mIU/L. There was significant difference of the level IGFBP-3 in OT groups with A-Ex groups (10.7 ± 9.9 vs 23.5 ± 9.7 mIU/L; p < 0,05. The significant difference was also observed in the level of IGFBP 3 between C groups and the OT-Hib groups (17.4 ± 10 vs 31.5 ± 6.2; p < 0.05.Conclusion: Administration of H. sabdariffa can prevent the decrease of IGFBP-3 levels in overtraining rats, indicating its role in preventing overtraining syndrome.

    Antiphospholipid syndrome (APS) is an acquired thrombophilia characterized by thrombosis, pregnancy morbidity, and the presence of characteristic antibodies. Current therapy for patients having APS with a history of thrombosis necessitates anticoagulation with the vitamin K antagonist warfarin, a challenging drug to manage. Apixaban, approved for the treatment and prevention of venous thrombosis with a low rate of bleeding observed, has never been studied among patients with APS. We report study rationale and design of Apixaban for the Secondary Prevention of Thrombosis Among Patients With Antiphospholipid Syndrome (ASTRO-APS), a prospective randomized open-label blinded event pilot study that will randomize patients with a clinical diagnosis of APS receiving therapeutic anticoagulation to either adjusted-dose warfarin or apixaban 2.5 mg twice a day. We aim to report our ability to identify, recruit, randomize, and retain patients with APS randomized to apixaban compared with warfarin. We will report clinically important outcomes of thrombosis and bleeding. All clinical outcomes will be adjudicated by a panel blinded to the treatment arm. A unique aspect of this study is the enrollment of patients with an established clinical diagnosis of APS. Also unique is our use of electronic medical record interrogation techniques to identify patients who would likely meet our inclusion criteria and use of an electronic portal for follow-up visit data capture. ASTRO-APS will be the largest prospective study to date comparing a direct oral anticoagulant with warfarin among patients with APS for the secondary prevention of thrombosis. Our inclusion criteria assure that outcomes obtained will be clinically applicable to the routine management of patients with APS receiving indefinite anticoagulation. © The Author(s) 2015.

    Trouvé, Arnaud; Wang, Yi

    2010-12-01

    This paper is aimed at illustrating the capabilities of contemporary large eddy simulation (LES) solvers for compartment fire applications. Compartment fires refer to fires occurring indoors and feature a variety of complex phenomena associated with smoke accumulation and restricted air ventilation. The article provides a brief presentation of the main features of compartment fire dynamics followed by a review of the modelling challenges found in a LES treatment of these dominant features. The discussion shows that in addition to a suitable model for the turbulent flow dynamics, simulations of compartment fires require a collection of physical sub-models in order to describe a large range of multi-physics phenomena, including pyrolysis processes, buoyancy-driven flow, combustion, soot formation and thermal radiation. Some examples of LES simulations of compartment fires are also presented, using two different solvers that represent the current state-of-the-art of compartment fire modelling: FDS developed by the National Institute of Standards and Technology, USA, and FireFOAM developed by FM Global, USA. Both solvers are available as free open-source software and are representative of ongoing efforts within the fire research and engineering community to self-organise and to promote the general area of LES-based fire modelling.

    2014-01-01

    Metabolic syndrome (MetS) has a huge impact on public health, and today lifestyle interventions remain the primary mode for MetS therapy. It is therefore important to elucidate the possible preventive effects of diet and foods, and their MetS-related health implications. To examine how fish consumption affects the development and prevalence of MetS, we systematically reviewed cross-sectional, prospective cohort, and intervention studies conducted among adults (humans) and, reporting consumption of fish or seafood as being related to MetS (prevalence or incidence), where MetS was defined via an established definition. The literature search in PubMed identified 502 citations, and after screening, 49 full-text articles were retrieved and assessed for eligibility. After excluding duplicates and those not meeting the inclusion criteria, seven studies from Croatia, Finland, France, Iceland, Iran, Korea, and US were included. Four studies (one follow-up and three cross-sectional) found associations between fish consumption and MetS (three among men, and one among women), suggesting that fish consumption may prevent or improve metabolic health and have a protective role in MetS prevention. This protective role might be related to gender, and men may benefit more from the consumption of fish. However, lack of controlling for potential confounders may also inflict the results. Additional research is required to further explore fish consumption and its potential role in improving or reversing MetS and its components.

    Berries belong to the best dietary sources of bioactive compounds, which exert a synergistic and cumulative effect on promotion of human health and prevention of diseases. The present review presents the most recent findings of animal and human studies regarding the health benefits of berries in terms of prevention and treatment of obesity, hypertension, type 2 diabetes, dyslipidemia, and nonalcoholic fatty liver disease. In the last years, there was a growing number of evidence from human epidemiological and interventional studies, which emphasized the role of berries in the management of metabolic diseases. Based on the results from recent clinical trials, it can be established that a berry diet rich in antioxidants and bioactive phytochemicals has beneficial effects on hepatic function, increase of insulin sensitivity and high-density lipoprotein-cholesterol, decrease of serum glucose and low-density lipoprotein-cholesterol, and finally is inversely associated with the incidence of type 2 diabetes. Numerous recent studies have shown that berries provide great benefits in preventing or mitigating metabolic disorders. The results of this review indicate that regular long-term consumption of different berries could potentially delay the progression of metabolic syndrome and comorbidities.

    2014-11-01

    The American Academy of Orthopaedic Surgeons recommends the use of vitamin C to prevent complex regional pain syndrome (CRPS) for patients with distal radius fractures (DRFs). We hypothesized that the evidence for supporting this recommendation is weak, based on epidemiological principles of association and causality. The specific aim of this project was to test the validity of this recommendation. We conducted a literature review to retrieve articles reporting on the use of vitamin C to prevent CRPS. Data collected included sample size, study design type, dose of vitamin C used, and outcome measures of association expressed as relative risk (RR) and odds ratio. We then applied Hill criteria to evaluate the relationship between vitamin C and CRPS. We obtained 225 articles from the database search. After the exclusion of duplicates, unrelated articles, editorial letters, and commentaries, we found 4 articles and 1 systematic review relevant to our topic. Six of the 9 Hill criteria were met, and an earlier meta-analysis showed a quantified reduction in CRPS risk. However, criteria like biological plausibility, specificity, and coherence were not met. The number of causal/association criteria met was adequate to support the scientific premise of the effect of vitamin C in preventing CRPS after DRF. Furthermore, vitamin C administration is of relatively low cost and has few complications unless administered in large doses. Owing to sufficient epidemiological evidence availability, the American Academy of Orthopaedic Surgeons recommendation of vitamin C to prevent CRPS has practical merit. Therapeutic II.

    High fructose consumption contributes to metabolic syndrome incidence, whereas exercise training promotes several beneficial adaptations. In this study, we demonstrated the preventive role of exercise training in the metabolic syndrome derangements in a rat model. Wistar rats receiving fructose overload in drinking water (100 g/l) were concomitantly trained on a treadmill (FT) or kept sedentary (F) for 10 wk. Control rats treated with normal water were also submitted to exercise training (CT) or sedentarism (C). Metabolic evaluations consisted of the Lee index and glycemia and insulin tolerance test (kITT). Blood pressure (BP) was directly measured, whereas heart rate (HR) and BP variabilities were evaluated in time and frequency domains. Renal sympathetic nerve activity was also recorded. F rats presented significant alterations compared with all the other groups in insulin resistance (in mg · dl(-1) · min(-1): F: 3.4 ± 0.2; C: 4.7 ± 0.2; CT: 5.0 ± 0.5 FT: 4.6 ± 0.4), mean BP (in mmHG: F: 117 ± 2; C: 100 ± 2; CT: 98 ± 2; FT: 105 ± 2), and Lee index (in g/mm: F = 0.31 ± 0.001; C = 0.29 ± 0.001; CT = 0.27 ± 0.002; FT = 0.28 ± 0.002), confirming the metabolic syndrome diagnosis. Exercise training blunted all these derangements. Additionally, FS group presented autonomic dysfunction in relation to the others, as seen by an ≈ 50% decrease in baroreflex sensitivity and 24% in HR variability, and increases in sympathovagal balance (140%) and in renal sympathetic nerve activity (45%). These impairments were not observed in FT group, as well as in C and CT. Correlation analysis showed that both Lee index and kITT were associated with vagal impairment caused by fructose. Therefore, exercise training plays a preventive role in both autonomic and hemodynamic alterations related to the excessive fructose consumption.

    Conclusions: RVIs are associated with high morbidity and mortality among SOT and HSCT recipients. Management options are currently limited or lack strong clinical evidence. As community and nosocomial spread has been reported for all reviewed RVIs, strict adherence to infection control measures is key to preventing outbreaks.

    Cockayne syndrome (CS) is a devastating autosomal recessive disease characterized by neurodegeneration, cachexia, and accelerated aging. 80% of the cases are caused by mutations in the CS complementation group B (CSB) gene known to be involved in DNA repair and transcription. Recent evidence...... indicates that CSB is present in mitochondria, where it associates with mitochondrial DNA (mtDNA). We report an increase in metabolism in the CSB(m/m) mouse model and CSB-deficient cells. Mitochondrial content is increased in CSB-deficient cells, whereas autophagy is down-regulated, presumably as a result...... of defects in the recruitment of P62 and mitochondrial ubiquitination. CSB-deficient cells show increased free radical production and an accumulation of damaged mitochondria. Accordingly, treatment with the autophagic stimulators lithium chloride or rapamycin reverses the bioenergetic phenotype of CSB...

    Meconium aspiration syndrome (MAS) is a life-threatening disorder in newborn infants. Universal intrapartum suction of infants with meconium stained amniotic fluid (MSAF) and postnatal suction of vigorous infants have been used in an attempt to decrease the incidence and severity of the disease by clearing the airway. Both procedures have been proven fruitless when challenged through randomised control trials (RCTs). Endotracheal intubation and suctioning are currently recommended only for non-vigorous infants. Respiratory failure in infants with MAS is frequently treated initially with conventional or synchronized mechanical ventilation. Surfactant administration and high-frequency ventilation (HFV) are commonly used as rescue therapy for severe cases. Nitric oxide (NO) is added when severe pulmonary hypertension is demonstrated. ECMO is an option when other treatments have failed. In the pathophysiology of severe MAS, asphyxia and pulmonary hypertension are considered to be more important than the obstruction of the airways and/or damage to the lung produced by meconium.

    Ritonavir is commonly used in low doses to boost plasma levels of protease inhibitors in patients with human immunodeficiency virus (HIV) infections. It is also a potent inhibitor of cytochrome P450. We present a 50-year-old African American male with past medical history of HIV on highly active antiretroviral therapy (HAART), which also included ritonavir and long standing asthma that has been treated with inhaled fluticasone, who presented with back pain. He had central obesity, prominent abdominal striae and wasted extremities on physical examination. Laboratory tests showed low morning serum cortisol and suboptimal cosyntropin test consistent with adrenal insufficiency. Computed tomography (CT) of the spine showed a fracture of inferior endplate of the lumbar (L3) vertebra. The cause of osteoporosis is believed to be iatrogenic Cushing syndrome caused by enhanced levels of inhaled fluticasone effects secondary to inhibition of cytochrome P450. The patient was managed surgically and fluticasone was discontinued.

    Full Text Available Irritable bowel syndrome (IBS is the most common functional gastrointestinal disorder yet it still lacks effective prevention therapies. The aim of this study is to determine whether a novel prebiotic blend (PB composed of fructo-oligosaccharide (FOS, galactooligosaccharide (GOS, inulin and anthocyanins could be effective in preventing the development of IBS. We explored the possible mechanisms both in animal and in cells. Post-infectious IBS models in C57BL/6 mice were established and were pretreated with the PB, PB and probiotic strains 8 weeks in advance of infection. Eight weeks after infection, intestinal tissues were collected for assessing histomorphology, visceral sensitivity, barrier function, pro-inflammatory cytokines expression and proteomics analysis. Fecal samples were also collected for microbiota analysis. The pro-inflammatory cytokines expression in Caco-2 cells were evaluated after co-incubation with PB and Salmonella typhimurium 14028. The results showed that PB significantly decreased the pro-inflammatory cytokines both in infected Caco-2 cells and PI-IBS models. The loss of body weight, decreased expression of tight junction protein Occludin (OCLN, and changes of the microbiota composition induced by infections could be greatly improved by PB intervention (p < 0.05. The proteomics analysis revealed that this function was associated with Peroxisome proliferator-activated receptor (PPARγ pathway.

    Full Text Available Several studies have shown that a poor vitamin D status may increase the risk of developing metabolic syndrome, which leaves the question whether improving one’s vitamin D status may reduce the risk for the syndrome. Here we investigate the effect of temporal changes in serum 25-hydroxyvitamin D (25(OHD concentrations on metabolic syndrome among Canadians enrolled in a preventive health program that promotes vitamin D supplementation. We accessed and analyzed data of 6682 volunteer participants with repeated observations on serum 25(OHD concentrations and metabolic syndrome. We applied logistic regression to quantify the independent contribution of baseline serum 25(OHD and temporal increases in serum 25(OHD to the development of metabolic syndrome. In the first year in the program, participants, on average, increased their serum 25(OHD concentrations by 37 nmol/L. We observed a statistical significant inverse relationship of increases in serum 25(OHD with risk for metabolic syndrome. Relative to those without improvements, those who improved their serum 25(OHD concentrations with less 25 nmol/L, 25 to 50 nmol/L, 50 to 75 nmol/L, and more 75 nmol/L had respectively 0.76, 0.64, 0.59, 0.56 times the risk for metabolic syndrome at follow up. These estimates were independent of the effect of baseline serum 25(OHD concentrations on metabolic syndrome. Improvement of vitamin D status may help reduce the public health burden of metabolic syndrome, and potential subsequent health conditions including type 2 diabetes and cardiovascular disease.

    Diet is recognized as a key factor in the cause and management of the metabolic syndrome (MetS). However, policies to guide preventive clinical nutrition interventions of the condition are limited. We examined the relation between dietary quality and incident MetS in adult women and identified foci for preventive nutrition interventions. This was a prospective study of 300 healthy women (aged 30-69 y) in the Framingham Offspring-Spouse study who were free of MetS risk factors at baseline. The development of individual MetS traits and overall MetS status during 12 y of follow-up were compared in women by tertile of nutritional risk, based on intake of 19 nutrients. Multivariate logistic regression models considered age, smoking, physical activity, and menopausal status. Baseline age-adjusted mean nutrient intake and ischemic heart disease risk profiles differed by tertile of nutritional risk. Women with higher nutritional risk profiles consumed more dietary lipids (total, saturated, and monounsaturated fats) and alcohol and less fiber and micronutrients; they had higher cigarette use and waist circumferences. Compared with women with the lowest nutritional risk, those in the highest tertile had a 2- to 3-fold risk of the development of abdominal obesity and overall MetS during 12 y of follow-up [odds ratio: 2.3 (95% CI: 1.2, 4.3) and 3.0 (95% CI: 1.2, 7.6), respectively]. Higher composite nutritional risk predicts the development of abdominal obesity and MetS during long-term follow-up in healthy women, independent of lifestyle and ischemic heart disease risk factors. Preventive nutrition interventions for obesity and MetS risk reduction should focus on the overall nutritional quality of women's dietary profiles.

    Complex regional pain syndrome type I (CRPS-I), previously known as reflex sympathetic dystrophy, is common after conservatively or surgically treated wrist fractures. Several studies support the efficacy of vitamin C in preventing CRPS-I, although the data are somewhat conflicting. The primary objective of this systematic literature review and meta-analysis was to assess the efficacy of vitamin C therapy in preventing CRPS-I after a wrist fracture. Randomised, placebo-controlled trials of vitamin C to prevent CRPS-I after wrist fractures were sought in the three main databases: PubMed (1980 to December 2015), CENTRAL (Central 2015, number 12), and Embase (1980 to December 2015). Two authors worked independently to select articles. Data from selected articles were collected independently. Three randomised placebo-controlled trials in a total of 875 patients were included. Treatment was non-operative in 758/890 (85.1%) fractures and operative in 132 (14.9%) fractures. Vitamin C supplementation was started on the day of the injury and continued for 50 days. In the group given 500mg of vitamin C daily, the risk ratio for CRPS-I was 0.54 (95%CI, 0.33-0.91; P=0.02). Thus, the risk of developing CRPS-I was significantly decreased by prophylactic treatment with 500mg of vitamin C per day. The heterogeneity rate was 65% (non-significant). Daily supplementation with 500mg of vitamin C per day for 50 days decreases the 1-year risk of CRPS-I after wrist fracture. II, systematic review of level I and II studies.

  11. Well begun is half done: Rubella virus perturbs autophagy signaling, thereby facilitating the construction of viral replication compartments.

    The rubella virus is the causative agent of postnatal German measles and the congenital rubella syndrome. The majority of the rubella virus replication complexes originate from the endomembrane system. The rubella virus perturbs the signaling pathways regulating the formation of autophagic membranes in the infected cells, including the Ras/Raf/MEK/ERK and PI3K/Akt pathways. It is widely accepted that these pathways inhibit autophagy. In contrast, the class III PI3K enzymes are essential for autophagy initiation. By manipulating the Ras/Raf/MEK/ERK, class I PI3K/Akt and class III PI3K axes of signal transduction, the rubella virus may differentially regulate the autophagic cascade, with consequent stimulation of the initiation and strong suppression of the later phases. Dysregulation of autophagy by this virus can have a significant impact on the construction of replication compartments by regulating membrane trafficking. We hypothesize that the rubella virus perturbs the autophagic process in order to prevent the degradation of the virus progeny, and to ensure its replication by hijacking omegasomes for the construction of the replication complexes. The virus is therefore able to utilize an antiviral mechanism to its own advantage. Therapeutic modalities targeting the autophagic process may help to ameliorate the serious consequences of the congenital rubella syndrome. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Full Text Available Metabolic syndrome (MetS is established as the combination of central obesity and different metabolic disturbances, such as insulin resistance, hypertension and dyslipidemia. This cluster of factors affects approximately 10%–50% of adults worldwide and the prevalence has been increasing in epidemic proportions over the last years. Thus, dietary strategies to treat this heterogenic disease are under continuous study. In this sense, diets based on negative-energy-balance, the Mediterranean dietary pattern, n-3 fatty acids, total antioxidant capacity and meal frequency have been suggested as effective approaches to treat MetS. Furthermore, the type and percentage of carbohydrates, the glycemic index or glycemic load, and dietary fiber content are some of the most relevant aspects related to insulin resistance and impaired glucose tolerance, which are important co-morbidities of MetS. Finally, new studies focused on the molecular action of specific nutritional bioactive compounds with positive effects on the MetS are currently an objective of scientific research worldwide. The present review summarizes some of the most relevant dietary approaches and bioactive compounds employed in the treatment of the MetS to date.

    Full Text Available Virgin olive oil (VOO constitutes the main source of fat in the Mediterranean diet. VOO is rich in oleic acid, displaying health-promoting properties, but also contains minor bioactive components, especially phenolic compounds. Hydroxytyrosol (HT, the main polyphenol of olive oil, has been reported to be the most bioactive component. This review aims to compile the results of clinical, animal and cell culture studies evaluating the effects of HT on the features of Metabolic Syndrome (MetS (body weight/adiposity, dyslipidemia, hypertension, and hyperglycemia/insulin resistance and associated complications (oxidative stress and inflammation. HT was able to improve the lipid profile, glycaemia, and insulin sensitivity, and counteract oxidative and inflammatory processes. Experimental studies identified multiple molecular targets for HT conferring its beneficial effect on health in spite of its low bioavailability. However, rodent experiments and clinical trials with pure HT at biologically relevant concentrations are still lacking. Moreover, the roles of intestine and its gut microbiota have not been elucidated.

    Horses metabolic disorders have become an important problem of modern veterinary medicine. Pathological obesity, insulin resistance and predisposition toward laminitis are associated with Equine Metabolic Syndrome (EMS). Based on pathogenesis of EMS, dietary and cell therapy management may significantly reduce development of this disorder. Special attention has been paid to the diet supplementation with highly bioavailable minerals and mesenchymal stem cells (MSC) which increase insulin sensitivity. In nutrition, there is a great interests in natural algae enriched via biosorption process with micro- and macroelements. In the case of cellular therapy, metabolic condition of engrafted cells may be crucial for the effectiveness of the therapy. Although, recent studies indicated on MSC deterioration in EMS individuals. Here, we described the combined nutritional and stem cells therapy for the EMS treatment. Moreover, we specified in details how EMS affects the adipose-derived stem cells (ASC) population. Presented here, combined kind of therapy- an innovative and cutting edge approach of metabolic disorders treatment may become a new gold standard in personalized veterinary medicine.

    Geurtsen, W; García-Godoy, F

    1999-12-01

    Several reports revealed that the cracked-tooth syndrome is a common problem in dental practice, which often results in extraction of the affected incompletely fractured teeth. Predominantly restored teeth suffer from these incomplete fractures. Therefore, it is of outstanding importance to stabilize teeth weakened due to cavity preparation. Besides full cuspal coverage by partial or full crowns, bonded restorations have been proposed for internal splinting of restored teeth. Although contradictory data have been published, there is evidence that bonded amalgam or resin-based composite restorations (RBC) do not increase fracture resistance of teeth with wide occlusal-proximal cavities to values similar to sound, unrestored controls. Indirectly fabricated RBC inlays and various ceramic inlays, however, increased fracture strength to levels as high as those of sound caries-free teeth. Therefore, it is recommended that weakened teeth with wide cavities be strengthened by full cuspal coverage with cast or ceramic restorations, by bonded ceramic inlays, or by indirectly-fabricated bonded RBC composite inlays.

    The number of patients suffering from a diabetic foot syndrome is increasing. In many cases large plantar or heel defects can only be reconstructed by using a free flap. The free parascapular flap is an alternative to free muscle flaps in the reconstruction of plantar or heel defects. Donor site morbidity is low. Autologous bypass reconstruction or an angioplasty can increase extremity perfusion. PATIENTS AND OPERATIONS: 52 patients with a diabetic foot syndrome have been reconstructed since 2007. 23 of them required a free tissue transfer. On average these patients were 68.7 years of age. A parascapular flap was used in 15 cases, a latissimus dorsi flap with a skin graft in 4 cases, a gracilis muscle flap with a skin graft in 3 cases. In one case a free instep flap of the contralateral foot, which had to be amputated, was used. In 13 cases the flap was anastomosed to the autologous bypass, in one case an AV loop was used. 22 flaps healed primarily. Only 1 patient was not able to walk at discharge. There was one flap loss. 4 patients required an amputation later on due to bypass failure or infection. 2 patients died due to cardiac arrest at the rehabilitation clinic. If the correct indication is met, free flaps can prevent diabetes-derived amputations of the lower limb. The parascapular flap can be used for plantar and heel defects. Flap harvesting is quick due to the constant vascular anatomy. The donor site morbidity is low. Reconstruction requires revascularisation in an interdisciplinary setting including vascular surgeons and radiologists. Limb salvage reduces mortality and improves quality of life. Revascularisation and reconstruction should best be done in a single surgical procedure. © Georg Thieme Verlag KG Stuttgart · New York.

  18. Lingering immune dysregulation of inflammatory dermatoses, particularly psoriasis, probably drives metabolic syndrome culminating in cardiovascular damage and needs preventive public health guidelines as well as comprehensive management

    Full Text Available Metabolic syndrome, a constellation of interrelated risk factors of metabolic origin namely, abdominal obesity, insulin resistance, dyslipidemia and hypertension, confers greater risk of cardiovascular disease on its patients than the sum of the individual components. It is increasingly being associated with inflammatory dermatoses, especially psoriasis. Determination of the diagnostic criteria of this syndrome is conditioned by the changing views regarding its pathogenesis. Approximately, a quarter of the world′s population harbors this syndrome, whose reported prevalence in India (5-30% has escalated with an increase in urbanization and socioeconomic status. Due to, up to 3 times, the risk of cardiovascular mortality and up to 24 times risk of diabetes mellitus, the epidemiological significance of metabolic syndrome ideally necessitates formulation of preventive guidelines by public health authorities. Chronic inflammation, involving several cytokines and adipokines, forms the bridge between this syndrome and psoriasis and underlies the formation of atherosclerotic plaque, the primary lesion of coronary artery disease, in whose pathogenesis oxidative stress and genetic factors also play a role. Up to 4-fold increase in the prevalence of metabolic syndrome and 3-fold increased risk of cardiovascular mortality is reported globally in psoriatics. Increasing index of suspicion of this syndrome by the dermatologists, prevention of cardiovascular damage by lifestyle modifications, smoking cessation and redressal of the inherent depression in these patients is as imperative in management as is the specific therapy of the skin lesions of this systemic, rather than "just a skin," disease as well as the lipid-lowering, antihypertensive and antidiabetic agents.

    Promoting the expansion of adult stem cell populations offers the potential to ameliorate radiation or chemotherapy-induced bone marrow failure and allows for expedited recovery for patients undergoing these therapies. Previous genetic studies suggested a pivotal role for SH2 domain-containing inositol-5-phosphatase 1 (SHIP1) in limiting the size of the hematopoietic stem cell (HSC) compartment. The aim of this study was to determine whether our recent development of small molecule SHIP1 inhibitors offers the potential for pharmacological expansion of the HSC compartment in vivo. We show here that treatment of mice with aminosteroid inhibitors of SHIP1 (SHIPi) more than doubles the size of the adult mesenchymal stem cell (MSC) compartment while simultaneously expanding the HSC pool sixfold. Consistent with its ability to target SHIP1 function in vivo, SHIPi also significantly increases plasma granulocyte colony-stimulating factor (G-CSF) levels, a growth factor that supports proliferation of HSC. Here, we show that SHIPi-induced G-CSF production mediates HSC and MSC expansion, as in vivo neutralization of G-CSF abrogates the SHIPi-induced expansion of both the HSC and MSC compartments. Due to its expansionary effect on adult stem cell compartments, SHIPi represents a potential novel strategy to improve declining stem cell function in both therapy induced and genetically derived bone marrow failure syndromes. © 2014 AlphaMed Press.

    To describe and evaluate a shaken baby prevention programme trialled in the Auckland District Health Board from January 2010, to December 2011. Development and implementation of the programme, telephone survey of a sample of caregivers and written survey of a sample of providers. At least 2,592 caregivers received the trial programme. 150 (6%) were surveyed by telephone a median of 6 weeks later. 128 (85%) remembered at least one key message, unprompted; most commonly "It's OK to walk away" (94/150, 63%). When asked, 92% had made a plan for what to do when frustrated and 63% had shared the information with others. Only 98/150 (65%) watched the programme DVD. Many said they already knew about the risks of shaking a baby, but still found the programme highly relevant. Thirty-one nurses were surveyed. There was a high degree of agreement that the programme was relevant. Barriers to programme delivery included time, workload and the documentation required. A shaken baby prevention programme adapted to New Zealand can be introduced in a District Health Board and is acceptable to caregivers and health professionals. Further research is needed to evaluate the content, mode of delivery and effectiveness of this programme.

    A high caloric intake in today's nutrition and a sedentary lifestyle are the main causes of the notable increase in obesity in our society. In turn, this results in an increase in associated pathologies, such as metabolic syndrome and diabetes type 2. In the present work we review most recent studies and programs, which are significant due to their sample size and geographical diversity. It clearly shows that changes in alimentation and lifestyles are an effective instrument for combatting or delaying the onset of these diseases. In this sense, prevention is also key to avoiding serious consequences related to diabetes and metabolic syndrome, which can affect the life of the population.

    The epidemic of obesity and diabetes in the United States poses major challenge to the prevention and management of chronic diseases. Furthermore, when this is viewed in other components of the metabolic syndrome (i.e., the burden of high cholesterol and hypertension), the prevalence of the metabolic syndrome continues to rise in the USA continued challenge is how to deal with this epidemic from a medical and public health standpoint. Community Based Participatory Research (CBPR) is a unique approach and offers a novel perspective for answering this challenge. A critical set of goals for CBPR is to address health disparities and social inequalities while getting community members engaged in all aspects of the research process. Utilizing the West Virginia Diabetes Prevention and Management Program and trained Health Coaches as a model, we discuss topics of consideration related to CBPR, involving trained health coaches, optimizing early adoption of healthy lifestyle behaviors, and enhancing participation. Through careful project planning and design, questions regarding disparities increasing susceptibility and preventive efforts within the community can be addressed successfully. These topics are part of a broader integration of theories such as participatory research, community engagement, and outcomes measurement. The understanding of the pathophysiology and epidemiology of the metabolic syndrome can help frame an appropriate strategy for establishing long-term community-wide changes that promote health. In order to continue to improve investigations for preventing the metabolic syndrome, it will be necessary to have aggressive efforts at the individual and population level for developing culturally sensitive programs that start early and are sustainable in practical environments such as the workplace. In this comprehensive review, we will discuss practical considerations related to project design, implementation, and how to measure effectiveness in regards to

    Full Text Available IntroductionPostoperative cognitive decline (PCD can affect in excess of 10% of surgical patients and can be considerably higher with risk factors including advanced age, perioperative infection, and metabolic conditions such as obesity and insulin resistance. To define underlying pathophysiologic processes, we used animal models including a rat model of metabolic syndrome generated by breeding for a trait of low aerobic exercise tolerance. After 35 generations, the low capacity runner (LCR rats differ 10-fold in their aerobic exercise capacity from high capacity runner (HCR rats. The LCR rats respond to surgical procedure with an abnormal phenotype consisting of exaggerated and persistent PCD and failure to resolve neuroinflammation. We determined whether preoperative exercise can rectify the abnormal surgical phenotype.Materials and methodsFollowing institutional approval of the protocol each of male LCR and male HCR rats were randomly assigned to four groups and subjected to isoflurane anesthesia and tibia fracture with internal fixation (surgery or anesthesia alone (sham surgery and to a preoperative exercise regimen that involved walking for 10 km on a treadmill over 6 weeks (exercise or being placed on a stationary treadmill (no exercise. Feces were collected before and after exercise for assessment of gut microbiome. Three days following surgery or sham surgery the rats were tested for ability to recall a contextual aversive stimulus in a trace fear conditioning paradigm. Thereafter some rats were euthanized and the hippocampus harvested for analysis of inflammatory mediators. At 3 months, the remainder of the rats were tested for memory recall by the probe test in a Morris Water Maze.ResultsPostoperatively, LCR rats exhibited exaggerated cognitive decline both at 3 days and at 3 months that was prevented by preoperative exercise. Similarly, LCR rats had excessive postoperative neuroinflammation that was normalized by

    Full Text Available White spot syndrome virus (WSSV has become epidemic in Indonesia and affecting shrimp aquaculture interm of its production. White spot syndrome virus is transmitted from one to other ponds, through crustacean, included planktonic copepode as carrier for WSSV and through water from affected shrimp pond. A cluster model, consist of shrimp grow out ponds surrounded by non-shrimp pond as a role of biosecurity has been developed. The model aimed to prevent white spot virus transmission in extensive giant tiger shrimp pond. The study was conducted in two sites at Demak District, Central Java Province. As the treatment, a cluster consist of three shrimp ponds in site I, and two shrimp ponds in site II, each was surrounded by buffer ponds rearing only finfish. As the control, five extensive shrimp grow out ponds in site I and three shrimp grow out ponds in site II, with shrimp pond has neither applied biosecurity nor surrounded by non-shrimp pond as biosecurity as well considered as control ponds. The results found that treatment of cluster shrimp ponds surrounded by non-shrimp ponds could hold shrimp at duration of culture in the grow out pond (DOC 105.6±4.5 days significantly much longer than that of control that harvested at 60.9±16.0 days due to WSSV outbreak. Survival rate in trial ponds was 77.6±3.6%, significantly higher than that of control at 22.6±15.8%. Shrimp production in treatment ponds has total production of 425.1±146.6 kg/ha significantly higher than that of control that could only produced 54.5±47.6 kg/ha. Implementation of Better Management Practices (BMP by arranging shrimp ponds in cluster and surrounding by non-shrimp ponds proven effectively prevent WSSV transmission from traditional shrimp ponds in surrounding area.

    In order to control the spread of rubella and reduce the risk for congenital rubella syndrome, an additional rubella vaccination program was set up for all secondary school students since 2008 in Zhejiang, China. We conducted a descriptive analysis of rubella incidence among different age groups from 2005 to 2015 and a serosurvey of female subjects aged 15-39 years to understand the possible effects of this immunization program. The average annual rubella incidence rate had decreased from 15.86 per 100,000 population (2005-2007) to 0.75 per 100,000 population (2013-2015) in Zhejiang. The decrease in the rate of rubella incidence in girls aged 15-19 years was more accelerated (from 138.30 to 0.34 per 100,000) than in the total population during 2008-2015 (from 32.20 to 0.46 per 100,000). Of 1225 female subjects in the serosurvey, 256 (20.9%) were not immune to rubella. The proportion of subjects immune to rubella was significantly different among different age groups (Wald χ2 = 22.19, p = 0.000), and subjects aged 15-19 years old had the highest immunity (88.0%). Rubella antibody levels were significantly lower in women aged 25-30 years with 26.7% of them not immune, followed by the group aged 20-24 years (25.0%) and 30-35 years (24.5%). Rubella vaccine included in the Expanded Program on Immunization together with vaccination activities for secondary school students can help in rubella control, particularly in targeted age groups in the program. Seroprevalence of antibodies to the rubella virus amongst the female population within childbearing age in Zhejiang, China, is still too low to provide immunity. In addition to vaccination programs in the secondary schools, rubella vaccination should also be encouraged in women of childbearing age, which can be done effectively combined with pre-marital examination in China.

    Insulin resistance and abdominal obesity are present in the majority of people with the metabolic syndrome. Antioxidant therapy might be a useful strategy for type 2 diabetes and other insulin-resistant states. The combination of vitamin C (Vc) and vitamin E has synthetic scavenging effect on free radicals and inhibition effect on lipid peroxidation. However, there are few studies about how to define the best combination of more than three anti-oxidants as it is difficult or impossible to test the anti-oxidant effect of the combination of every concentration of each ingredient experimentally. Here we present a math model, which is based on the classical Hill equation to determine the best combination, called Fixed Dose Combination (FDC), of several natural anti-oxidants, including Vc, green tea polyphenols (GTP) and grape seed extract proanthocyanidin (GSEP). Then we investigated the effects of FDC on oxidative stress, blood glucose and serum lipid levels in cultured 3T3-L1 adipocytes, high fat diet (HFD)-fed rats which serve as obesity model, and KK-ay mice as diabetic model. The level of serum malondialdehyde (MDA) in the treated rats was studied and Hematoxylin-Eosin (HE) staining or Oil red slices of liver and adipose tissue in the rats were examined as well. FDC shows excellent antioxidant and anti-glycation activity by attenuating lipid peroxidation. FDC determined in this investigation can become a potential solution to reduce obesity, to improve insulin sensitivity and be beneficial for the treatment of fat and diabetic patients. It is the first time to use the math model to determine the best ratio of three anti-oxidants, which can save much more time and chemical materials than traditional experimental method. This quantitative method represents a potentially new and useful strategy to screen all possible combinations of many natural anti-oxidants, therefore may help develop novel therapeutics with the potential to ameliorate the worldwide metabolic

    Metabolic syndrome (MetS) is a constellation of cardiovascular risk factors that increases the risk of cardiovascular disease, diabetes mellitus and all cause mortality. Long-term survivors of hematopoietic cell transplantation (HCT) have a substantial risk of developing MetS and cardiovascular disease, with the estimated prevalence of MetS being 31–49% among HCT recipients. Although MetS has not yet been proven to impact cardiovascular risk after HCT, an understanding of the incidence and risk factors for MetS in HCT recipients can provide the foundation to evaluate screening guidelines and develop interventions that may mitigate cardiovascular-related mortality. A working group was established through the Center for International Blood and Marrow Transplant Research and the European Group for Blood and Marrow Transplantation with the goal of reviewing literature and recommend practices appropriate to HCT recipients. Here we deliver consensus recommendations to help clinicians provide screening and preventive care for MetS and cardiovascular disease among HCT recipients. All HCT survivors should be advised of the risks of MetS and encouraged to undergo recommended screening based on their predisposition and ongoing risk factors. PMID:27548466

    Full Text Available Objective: Polycystic ovarian syndrome (PCOS is a common condition amongst women of reproductive age that can result in increased mortality and morbidity in women due to increased risk of diabetes mellitus and cardiovascular diseases. The aim of this systematic review was to assess the effectiveness of common treatments of PCOS on the predictors of diabetes in non-diabetic PCOS women.Materials and methods: An extensive search was performed on the publications in three medical databases including pubmed, scopus and google scholar from 1995 till 2017. The articles were screened based on their quality and included in this systematic review. A total of 25 articles including cohort, randomised controlled trial, review and meta-analysis were included in the review.Results: This systematic review revealed that the effect of lifestyle modification might be low in PCOS subjects due to high drop-out rate while the benefits of this intervention including weight and fat reduction may not be achieved by medical interventions. Metformin treatment may result in improvements in insulin sensitivity while its weight reduction effect is still not documented in PCOS subjects. Thiazolidendiones might be tolerated by the PCOS subjects and may result in similar effects as metformin but this effect should be documented by further studies.Conclusion: Combination of lifestyle modification with metformin or thiazolidinedions might improve the outcome of the prevention strategies. On the other hand this study revealed a different response to treatments in non-obese compared with obese PCOS subjects.

    The merits and demerits of food with health claims for the prevention of metabolic syndrome (MS) are reviewed. One major underlying cause of MS is obesity. Diet and lifestyle changes remain the cornerstones of therapy for obesity, but resulting weight loss is often small and long-term success is extremely uncommon and disappointing. Many anti-obesity drugs have been associated with unintended therapeutic outcomes. Currently, only one drug (mazindol) is approved in Japan for short-term treatment of individuals with a BMI over 35 kg/m(2). Treatment with orlistat with dietary modification, caffeine, or protein supplementation; consuming a low-fat diet; adherence to physical activity routines; prolonged contact with participants; problem-solving therapy; and the alternative treatment of acupressure are efficacious in reducing weight regain after weight loss treatment. Because obesity is highly stigmatized, any effective treatment should be made available to improve quality of life and self-image. Therefore, it is necessary to provide information to consumers through the media concerning 1) basic knowledge about health foods and laws concerning them, 2) scientifically based information on safety/effectiveness of health foods and food elements, and 3) reports on health disturbances associated with health foods around the world.

    Conquering disease and ill health has been an age old pursuit of man. The scientific and technological revolution of the last century ushered in major and important advances in preventive and curative medical technology which fired a new hope in the fight against communicable diseases. However, the experience over centuries shows that major decline in communicable diseases began much before the advent of modern technology due to advances in the socio-economic and environmental conditions of the people. There has been an attempt by the multilateral and unilateral agencies to supplant the expedient of technological interventions like vaccination campaigns as a substitute to socio-economic advancement in the third world countries. The dividends of this approach have been equivocal and have had an effect of distorting public health priorities in the third world. There seems to be an obsession with technology among the policy planners - a phenomenon that we call as techno-centrism; the latest example of which is the pulse polio campaign. This paper draws upon an epidemiological approach to vaccination programs as a tool to unravel this phenomenon.

To study the opportunities to increase the efficiency of pathogenetic therapy in patients with chronic cerebrovascular diseases (CVD (discirculatory encephalopathy, DE on the background of metabolic syndrome (MS using the drug Vitaxon®. The feature of the work was to identify strategic areas of the brain in cognitive and emotional disorders in patients with MS and its absence. Materials and methods. We observed 49 patients with DE II degree aged 37 to 73 years against the background of MS. The main group — 30 patients — received Vitaxon® as a part of treatment. The control group consisted of 19 patients with DE degree II following MS, comparable in the age and stage of the disease, who were not taking Vitaxon®. Patients were observed for 12 weeks. In addition to neurological, general clinical examinations, detection of MS signs, we have used neuropsychological tests by Mini Mental State Examination (MMSE and Montreal Cognitive Assessment (МоСА, Spielberger anxiety scale; Beck depression scale; study of attention: search of numbers by Schulte tables with the assessment of task-performance time. The brain and its liquor system in 41 patients (27 patients with MS — the first group and 14 patients without MS — the second group were evaluated using the method of volumetry (measuring the volume of certain brain regions, on the magnetic resonance imaging scanner Toshiba Vantage Titan 1.5. Results. Cognitive impairment in both groups manifested by the loss of memory, attention disorders, slowing of mental processes. After 12 weeks, the median by the MMSE significantly increased by 3.3 % (p < 0.05 compared with the first test in patients who received Vitaxon®. By МоСА, which is more sensitive when determining the mild cognitive impairment, in a group of Vitaxon® cognitive functions improved by 5 %, while in the control group — by 1.66 %. By Spielberger scale, state anxiety indicators improved more in the group of

    The association between the functional decline occurring with bedrest and hospitalization in older persons is well-known. A long wait in the emergency department (ED), where patients can be bedridden, is a risk factor for the development of an immobilization syndrome (IS). IS is one of the unwanted consequences of inactivity, which causes pathological changes in most organs and systems. Early mobility interventions, such as physical therapy (PT) delivered in the ED, may prevent its development. To our knowledge, no prior studies have reported on this topic. The goal of this study was to (i) assess the feasibility and (ii) explore the potential clinical value of adding PT services to the ED, in collaboration with nursing staff, to prevent IS. For 12 weeks, PT services were delivered in the ED to older persons (>65 years old) presenting with ≥1 clinical signs associated with the development of IS. Patients were screened by ED nurses and then seen by the physiotherapist. In order to assess feasibility, access to patients, percentage of patients who met eligibility criteria, acceptability of the intervention, and barriers/facilitators to the implementation were measured. To describe the clinical benefits of early PT services, we counted the number of new IS cases among patients after their admission to the ward. After 12 weeks, the ED nurses screened 187 potential patients and 20 received PT services in the ED (before their admission to the ward). Accessibility was not an issue and we observed good acceptability from the milieu. We did not find majors problems or insurmountable obstacles to implementation of the intervention. Clinical outcomes showed that nine patients received PT treatments in the ED and on the ward (after their admission). For the 11 other patients, no PT interventions were done in the ED following the assessment. Follow-up of these 11 patients showed that two of them developed IS during their hospital stay. As for the nine patients who began

    Sepsis causes more than with 215,000 deaths per year in the United States alone. Death can be caused by multiple system organ failure, with the lung, in the form of the acute respiratory distress syndrome (ARDS), often being the first organ to fail. We developed a chronic porcine model of septic shock and ARDS and hypothesized that blocking the proteases neutrophil elastase (NE) and matrix metalloproteinases (MMP-2 and MMP-9) with the modified tetracycline, COL-3, would significantly improve morbidity in this model. Pigs were anesthetized and instrumented for hemodynamic monitoring and were then randomized to one of three groups: control (n = 3), laparotomy only; superior mesenteric artery occlusion (SMA) + fecal blood clot (FC; n = 7), with intraperitoneal placement of a FC; and SMA + FC + COL (n = 5), ingestion of COL-3 12 h before injury. Animals emerged from anesthesia and were monitored and treated with fluids and antibiotics in an animal intensive care unit continuously for 48 h. Serum and bronchoalveolar lavage fluid (BALF) were sampled and bacterial cultures, MMP-2, MMP-9, NE, and multiple cytokine concentrations were measured. Pigs were reanesthetized and placed on a ventilator when significant lung impairment occurred (PaO2/FiO2 < 250). At necropsy, lung water and histology were assessed. All animals in the SMA + FC group developed septic shock evidenced by a significant fall in arterial blood pressure that was not responsive to fluids. Lung injury typical of ARDS (i.e., a fall in lung compliance and PaO2/FiO2 ratio and a significant increase in lung water) developed in this group. Additionally, there was a significant increase in plasma IL-1 and IL-6 and in BALF IL-6, IL-8, IL-10, NE, and protein concentration in the SMA + FC group. COL-3 treatment prevented septic shock and ARDS and significantly decreased cytokine levels in plasma and BALF. COL-3 treatment also significantly reduced NE activity (P < 0.05) and reduced MMP-2 and MMP-9 activity in BALF by

    A simple aerosol transport model was developed for a multi-compartmented cleanroom. Each compartment was treated as a well-mixed volume with ventilating supply and return air. Gravitational settling, intercompartment transport, and leakage of exterior air into the system were included in the model. A set of first order, coupled, ordinary differential equations was derived from the conservation equations of aerosol mass and air mass. The system of ODEs was then solved in MATLAB using pre-existing numerical methods. The model was verified against cases of (1) constant inlet-duct concentration, and (2) exponentially decaying inlet-duct concentration. Numerical methods resulted in normalized error of less than 10 -9 when model solutions were compared to analytical solutions. The model was validated against experimental measurements from a single field test and showed good agreement in the shape and magnitude of the aerosol concentration profile with time.

    Division of the mediastinum into compartments is used to help narrow the differential diagnosis of newly detected mediastinal masses, to assist in planning biopsy and surgical procedures, and to facilitate communication among clinicians of multiple disciplines. Several traditional mediastinal division schemes exist based upon arbitrary landmarks on the lateral chest radiograph. We describe a modern, computed tomography-based mediastinal division scheme, which has been accepted by the International Thymic Malignancy Interest Group as a new standard. This clinical classification defines a prevascular (anterior), a visceral (middle), and a paravertebral (posterior) compartment, with anatomic boundaries defined clearly by computed tomography. It is our intention that this definition be used in the reporting of clinical cases and the design of prospective clinical trials.

    In connection with the enhancement of the nuclear safety of the Jaslovske Bohunice V-1 NPP actions for the increase of the leak tightness are performed. The reconstruction has been done in the following directions: hermetic compartments leak tightness enhancement; air lock installation; installation of air lock in SP 4 vent system; integrated leakage rate test to hermetic compartments with leak detection. After 'major' leaks on the hermetic boundary components had been eliminated, since 1994 works on a higher qualitative level began. The essence of the works consists in the detection and identification of leaks in the structural component of the hermetic boundary during the planned refueling outages. The results of the Small Reconstruction and gradual enhancement of leak tightness are presented

    Obesity has become a severe health problem in the world. Even a moderate 5% weight loss can significantly reduce the prevalence of metabolic syndrome, which can be vital for preventing comorbidities caused by the obesity. Health Behavior Change Support Systems (hBCSS) emphasize an autogenous approach, where an individual uses the system to influence one's own attitude or behavior to achieve his or her own goal. Regardless of promising results, such health interventions technology has often been considered merely as a tool for delivering content that has no effect or value of its own. More research on actual system features is required. The objective of this study is to describe how users perceive persuasive software features designed and implemented into a support system. The research medium in this study is a web-based information system designed as a lifestyle intervention for participants who are at risk of developing a metabolic syndrome or who are already suffering from it. The system was designed closely following the principles of the Persuasive Systems Design (PSD) model and the Behavior Change Support Systems (BCSS) framework. A total of 43 system users were interviewed for this study during and after a 52 week intervention period. In addition, the system's login data and subjects' Body Mass Index (BMI) measures were used to interpret the results. This study explains in detail how the users perceived using the system and its persuasive features. Self-monitoring, reminders, and tunneling were perceived as especially beneficial persuasive features. The need for social support appeared to grow along the duration of the intervention. Unobtrusiveness was found to be very important in all stages of the intervention rather than only at the beginning. Persuasive software features have power to affect individuals' health behaviors. Through their systematicity the PSD model and the BCSS framework provide effective support for the design and development of

    Crop uptake of perfluoroalkyl acids (PFAAs) from biosolids-amended soil has been identified as a potential pathway for PFAA entry into the terrestrial food chain. This study compared the uptake of PFAAs in greenhouse-grown radish (Raphanus sativus), celery (Apium graveolens var.dulce), tomato (Lycopersicon lycopersicum), and sugar snap pea (Pisum sativum var. macrocarpon) from an industrially impacted biosolids-amended soil, a municipal biosolids­ amended soil, and a control soil. Individual concentrations of PFAAs, on a dry weight basis, in mature, edible portions of crops grown in soil amended with PFAA industrially impacted biosolids were highest for perfluorooctanoate (PFOA; 67 ng/g) in radish root, perfluorobutanoate (PFBA;232 ng/g) in celery shoot, and PFBA (150 ng/g) in pea fruit. Comparatively, PFAA concentrations in edible compartments of crops grown in the municipal biosolids-amended soil and in the control soil were less than 25 ng/g. Bioaccumulation factors (BAFs) were calculated for the root, shoot, and fruit compartments (as applicable) of all crops grown in the industrially impacted soil. BAFs were highest for PFBA in the shoots of all crops, as well as in the fruit compartment of pea. Root­ soil concentration factors (RCFs) for tomato and pea were independent of PFAA chain length, while radish and celery RCFs showed a slight decrease with increasing chain length. Shoot-soil concentration factors (SCFs) for all crops showed a decrease with incre

No other relevant differences in outcomes were noted. Both animal derived surfactant extracts and protein free synthetic surfactant extracts are effective in the treatment and prevention of respiratory distress syndrome. Comparative trials demonstrate greater early improvement in the requirement for ventilator support, fewer pneumothoraces, and fewer deaths associated with animal derived surfactant extract treatment. Animal derived surfactant may be associated with an increase in necrotizing enterocolitis and intraventricular hemorrhage, though the more serious hemorrhages (Grade 3 and 4) are not increased. Despite these concerns, animal derived surfactant extracts would seem to be the more desirable choice when compared to currently available protein free synthetic surfactants.

    Familial cold autoinflammatory syndrome (FCAS) is an autosomal dominant disorder characterised by recurrent episodes of rash, arthralgia, and fever after cold exposure. The genetic basis of this disease has been elucidated. Cryopyrin, the protein that is altered in FCAS, is one of the adaptor proteins that activate caspase 1, resulting in release of interleukin 1. An experimental cold challenge protocol was developed to study the acute inflammatory mechanisms occurring after a general cold exposure in FCAS patients and to investigate the effects of pretreatment with an antagonist of interleukin 1 receptor (IL-1Ra). ELISA, real-time PCR, and immunohistochemistry were used to measure cytokine responses. After cold challenge, untreated patients with FCAS developed rash, fever, and arthralgias within 1-4 h. Significant increases in serum concentrations of interleukin 6 and white-blood-cell counts were seen 4-8 h after cold challenge. Serum concentrations of interleukin 1 and cytokine mRNA in peripheral-blood leucocytes were not raised, but amounts of interleukin 1 protein and mRNA were high in affected skin. IL-1Ra administered before cold challenge blocked symptoms and increases in white-blood-cell counts and serum interleukin 6. The ability of IL-1Ra to prevent the clinical features and haematological and biochemical changes in patients with FCAS indicates a central role for interleukin 1beta in this disorder. Involvement of cryopyrin in activation of caspase 1 and NF-kappaB signalling suggests that it might have a role in many chronic inflammatory diseases. These findings support a new therapy for a disorder with no previously known acceptable treatment. They also offer insights into the role of interleukin 1beta in more common inflammatory diseases.

    OBJECTIVE Sickle cell disease (SCD) in combination with moyamoya syndrome (MMS) represents a rare complication of SCD, with potentially devastating neurological outcomes. The effectiveness of surgical revascularization in this patient population is currently unclear. The authors' aim was to determine the effectiveness of surgical intervention in their series of SCD-MMS patients by comparing stroke recurrence in those undergoing revascularization and those undergoing conservative transfusion therapy. METHODS The authors performed a retrospective chart review of patients with MMS who were seen at the Johns Hopkins Medical Institution between 1990 and 2013. Pediatric patients (age < 18 years) with confirmed diagnoses of SCD and MMS were included. Intracranial stroke occurrence during the follow-up period was compared between surgically and conservatively managed patients. RESULTS A total of 15 pediatric SCD-MMS patients (28 affected hemispheres) were included in this study, and all were African American. Seven patients (12 hemispheres) were treated with indirect surgical revascularization. The average age at MMS diagnosis was 9.0 ± 4.0 years, and 9 patients (60.0%) were female. Fourteen patients (93.3%) had strokes before diagnosis of MMS, with an average age at first stroke of 6.6 ± 3.9 years. During an average follow-up period of 11.6 years, 4 patients in the conservative treatment group experienced strokes in 5 hemispheres, whereas no patient undergoing the revascularization procedure had any strokes at follow-up (p = 0.029). Three patients experienced immediate postoperative transient ischemic attacks, but all recovered without subsequent strokes. CONCLUSIONS Indirect revascularization is suggested as a safe and effective alternative to the best medical therapy alone in patients with SCD-MMS. High-risk patients managed on a regimen of chronic transfusion should be considered for indirect revascularization to maximize the effect of stroke prevention.

    The objective of this retrospective cohort study was to assess the impact of implementation of different levels of infection prevention and control (IPC) measures during an outbreak of Middle East respiratory syndrome (MERS) in a large tertiary hospital in Saudi Arabia. The setting was an emergency room (ER) in a large tertiary hospital and included primary and secondary MERS patients. Rapid response teams conducted repeated assessments of IPC and monitored implementation of corrective measures using a detailed structured checklist. We ascertained the epidemiologic link between patients and calculated the secondary attack rate per 10,000 patients visiting the ER (SAR/10,000) in 3 phases of the outbreak. In phase I, 6 primary cases gave rise to 48 secondary cases over 4 generations, including a case that resulted in 9 cases in the first generation of secondary cases and 21 cases over a chain of 4 generations. During the second and third phases, the number of secondary cases sharply dropped to 18 cases and 1 case, respectively, from a comparable number of primary cases. The SAR/10,000 dropped from 75 (95% confidence interval [CI], 55-99) in phase I to 29 (95% CI, 17-46) and 3 (95% CI, 0-17) in phases II and III, respectively. The study demonstrated salient evidence that proper institution of IPC measures during management of an outbreak of MERS could remarkably change the course of the outbreak.

    Hyaline membrane disease (HMD) is leading single cause of death of newborn, premature infants. The "hyaline membranes" consist chiefly of fibrin. The clinical manifestation of HMD is the respiratory distress syndrome (RDS). Infants with RDS were treated with urokinase-activated human plasmin in a previous clinical trial. Survival rate was increased in the plasmin treated group as compared to the placebo recipients. However, cost and difficulty in the preparation of the enzyme made this treatment impractical. We, as well as others, have shown the premature infants lack serum plasminogen; thus they are unable to develop effective fibrinolysis and are defenseless against pulmonary fibrin deposition. Therefore, plamsinogen was tested as a possible preventive agent in RDS due to HMD. In a double blind, randomized study, infants between 1 and 2.5 kg birth weight received plasminogen or placebo shortly after birth, and were then followed for development of RDS. After 100 infants were entered into the study, the code was broken and results were evaluated to assure safety of the procedure. Among the 100 infants, 51 received placebo, 49 received plasminogen. Among the infants who received placebo, seven developed mild, and ten developed severe respiratory distress; of these ten, five died with histopathologically documented HMD. Two infants died from causes other than HMD. Among the 49 infants treated with plasminogen, 13 developed mild and three developed severe respiratory distress. There was no death due to HMD. Two deaths were due to other causes. Factors placing the infant at risk from HMD (degree of prematurity, sex, cesarean section, bleeding episodes during pregnancy, maternal diabetes) were found to be evenly distributed between control and treated groups. Since completing the first phase of the study, data of an additional 277 infants has become available. Although the code was not broken in this series, a preliminary look at mortality data in comparison with

    Glial cells surround neuronal endings to create enclosed compartments required for neuronal function. This architecture is seen at excitatory synapses and at sensory neuron receptive endings. Despite the prevalence and importance of these compartments, how they form is not known. We used the main sensory organ of C. elegans, the amphid, to investigate this issue. daf-6/Patched-related is a glia-expressed gene previously implicated in amphid sensory compartment morphogenesis. By comparing time series of electron-microscopy (EM) reconstructions of wild-type and daf-6 mutant embryos, we show that daf-6 acts to restrict compartment size. From a genetic screen, we found that mutations in the gene lit-1/Nemo-like kinase (NLK) suppress daf-6. EM and genetic studies demonstrate that lit-1 acts within glia, in counterbalance to daf-6, to promote sensory compartment expansion. Although LIT-1 has been shown to regulate Wnt signaling, our genetic studies demonstrate a novel, Wnt-independent role for LIT-1 in sensory compartment size control. The LIT-1 activator MOM-4/TAK1 is also important for compartment morphogenesis and both proteins line the glial sensory compartment. LIT-1 compartment localization is important for its function and requires neuronal signals. Furthermore, the conserved LIT-1 C-terminus is necessary and sufficient for this localization. Two-hybrid and co-immunoprecipitation studies demonstrate that the LIT-1 C-terminus binds both actin and the Wiskott-Aldrich syndrome protein (WASP), an actin regulator. We use fluorescence light microscopy and fluorescence EM methodology to show that actin is highly enriched around the amphid sensory compartment. Finally, our genetic studies demonstrate that WASP is important for compartment expansion and functions in the same pathway as LIT-1. The studies presented here uncover a novel, Wnt-independent role for the conserved Nemo-like kinase LIT-1 in controlling cell morphogenesis in conjunction with the actin cytoskeleton

    Snapping phenomena result from the sudden impingement between anatomical and/or heterotopical structures with subsequent abrupt movement and noise. Snaps are variously perceived by patients, from mild discomfort to significant pain requiring surgical management. snapping syndrome occurs at various site like hip, knee, shoulder and wrist. There are many cadaveric studies shows accessory tendon in first extensor compartment of wrist. We present a 19 year old male presents catching sensation and occasional radial side wrist pain for 6 months. Finkelstein test was negative. Radiograph showed small bony projection over the radial styloid. MRI wrist was reported as normal but retrospective analysis of image shows multiple tendons. Intraopertively we found multiple accessory tendon of extensor pollicis brevis which is causing snapping. Fibrous tunnel release with tenotomy of few accessory tendons done. On table patients catching sensation was assessed and found to be relieved. Patient is not having snapping on his follow up visit and able to carry out his daily activity without difficulties. There are various causes for snapping wrist syndrome. Multiple accessory tendon can also cause snapping as shown in this case report. Moreover am presenting this case to highlight the diagnostic failure with non dynamic radiological investigation and to consider multiple accessory tendon as differential diagnosis for snapping wrist syndrome. Also suggest dynamic study could be a better choice of investigation to diagnosis snapping syndrome. First compartment tunnel release with few accessory tendon slip tenotomy gives good result.

    The aim of this study was to explore mental health staffs' experiences of assisting people with psychotic disorders to implement lifestyle changes in an effort to prevent metabolic syndrome. Qualitative interviews were conducted with 12 health care professionals working in psychosis outpatient care in Sweden. Data were analysed using a qualitative content analysis. The results illustrate that implementation of lifestyle changes among people with psychotic disorders was experienced as difficult, but possible. The greatest obstacles experienced in this work were difficulties due to the reduction of cognitive functions associated with the disease. Guidelines available to staff in order to help them identify and prevent physical health problems in the group were not always followed and the content was not always relevant. Staff further described feelings of uncertainty about having to motivate people to take anti-psychotic medication while simultaneously being aware of the risks of metabolic deviations. Nursing interventions focusing on organising daily routines before conducting a more active prevention of metabolic syndrome, including information and practical support, were experienced as necessary. The importance of healthy eating and physical activity needs to be communicated in such a way that it is adjusted to the person's cognitive ability, and should be repeated over time, both verbally and in writing. Such efforts, in combination with empathic and seriously committed community-based social support, were experienced as having the best effect over time. Permanent lifestyle changes were experienced as having to be carried out on the patient's terms and in his or her home environment.

    Objective: To evaluate the impact of different intervention models on adherence to secondary prevention therapies in patients with acute coronary syndrome (ACS). Methods: This multi-center cross-sectional study collected data from 34 hospitals covering 22 provinces in China. Hospitals were randomly divided into four groups: control group(routine treatment and care), promotional calendar group (routine treatment and care plus giving propaganda desk calendar to patients), education group (routine treatment and care add patients education by nurses) and combined intervention group (promotional calendar and education).At least 90 patients with ACS were consecutively enrolled from each involved hospital from April 15, 2012 to June 30, 2013. To reduce the impact of uneven distribution of inter-group variables on the results, 1∶1∶1∶1 propensity score matching method was used. The drug usage for secondary prevention and prognosis wasobtainedat 6 months after hospital discharge. Results: (1) A total of 3 391 patients were selected and 2 244 patients were included for the final analysisafter propensity score analysis. (2) At 6 months after discharge, the adherence rates of antiplatelet, statins, angiotensin converting enzyme inhibitor(ACEI)/angiotensin Ⅱ receptor blocker(ARB), β-blocker and the combination of 4 medications were similar between control group and promotional calendar group (all P> 0.016).The adherence rates of antiplatelet and statins were 97.0% (526/542) and 91.0% (493/542) in the education group, 3.7% and 5.5% higher than in the control group (both Ppromotional calendar group, and the statins adherence rate was 5.5%( OR= 1.055, 95% CI 1.012-1.101, Ppromotional calendar group, respectively, and statin adherence was 6.1% ( OR= 1.061, 95% CI 1.017-1.107, Ppromotional calendar group and education group.

    The great majority of mathematical models proposed to simulate malware spreading are based on systems of ordinary differential equations. These are compartmental models where the devices are classified according to some types: susceptible, exposed, infectious, recovered, etc. As far as we know, there is not any model considering the special class of carrier devices. This type is constituted by the devices whose operative systems is not targeted by the malware (for example, iOS devices for Android malware). In this work a novel mathematical model considering this new compartment is considered. Its qualitative study is presented and a detailed analysis of the efficient control measures is shown by studying the basic reproductive number.

    Secondary prevention after acute coronary syndrome (ACS) could reduce morbidity and mortality, but guideline targets are seldom reached. We hypothesized that nurse-led telephone-based intervention would increase adherence. The NAILED ACS trial is a prospective, controlled, randomized trial. Patients admitted for ACS at Östersund hospital, Sweden, were randomized to usual follow-up by a general practitioner or a nurse-led intervention. The intervention comprised telephone follow-up after 1 month and then yearly with lifestyle counselling and titration of medications until reaching target values for LDL-C (Nurse-led telephone-based secondary prevention was significantly more efficient at improving LDL-C and diastolic BP levels than usual care. The effect of the intervention declined between 1 and 12 months. Further evaluation of the persistence to the intervention is needed.

    Obesity-fuelled metabolic syndrome and diabetes is now a global epidemic. There is increasing evidence that these and other chronic conditions have common inflammatory antecedents. There is an interest in nutritionally based anti-inflammatory treatments for type 2 diabetes and metabolic syndrome. The aim of this review is to examine the evidence from a 5-year period; 2011-2016, for nutritionally based anti-inflammatory treatments for the Metabolic Syndrome and Type 2 Diabetes Mellitus. A literature search produced a total number of 1377 records, of which 26 papers were evaluated. Literature was analysed and tabulated according to date, outcome measures and results. The evidence is strong for use of polyphenolic compounds, fish oils and vitamins in reducing inflammation biomarkers, however the impact on metabolic control is less evident.

    Animal-derived surfactants have been shown to have several advantages over the first generation synthetic surfactants and are the most commonly used surfactant preparations. The animal-derived surfactants in clinical use are minced or lavaged and modified or purified from bovine or porcine lungs. It is unclear whether significant differences in clinical outcome exist among the available bovine (modified minced or lavage) and porcine (minced or lavage) surfactant extracts. To compare the effect of administration of different animal-derived surfactant extracts on the risk of mortality, chronic lung disease, and other morbidities associated with prematurity in preterm infants at risk for or having respiratory distress syndrome (RDS). We used the standard search strategy of the Cochrane Neonatal Review group to search the Cochrane Central Register of Controlled Trials (CENTRAL 2015, Issue 7), MEDLINE via PubMed (1966 to July 31, 2015), EMBASE (1980 to July 31, 2015), and CINAHL (1982 to July 31, 2015). We also searched clinical trials databases, conference proceedings, and the reference lists of retrieved articles for randomized controlled trials and quasi-randomized trials. Randomized or quasi-randomized controlled trials that compared the effect of animal-derived surfactant extract treatment administered to preterm infants at risk for or having RDS to prevent complications of prematurity and mortality. Data regarding clinical outcomes were excerpted from the reports of the clinical trials by the review authors. Subgroup analyses were performed based on gestational age, surfactant dosing and schedule, treatment severity and treatment strategy. Data analysis was performed in accordance with the standards of the Cochrane Neonatal Review Group. Sixteen randomized controlled trials were included in the analysis.

    A hundred limbs of patients suffering limb trauma were assessed by at least two different reviewers for symptoms of compartment syndrome, both clinically, and by a simple, locally devised apparatus for pressure measurement. We have found the apparatus to be very effective, safe, reproducible and simple. Orthopaedic surgeons working in peripheral hospitals in the developing world can make use of this apparatus which costs less than 5 dollars to assemble. This technique may assist an early decision regarding surgical decompression at a peripheral hospital or referral to specialist unit, thus saving valuable time and expense.

    The fungal communities of different soil compartments in mangrove ecosystem are poorly studied. We sequenced the internal transcribed spacer (ITS) regions to characterize the fungal communities in Avicennia marina root-associated soils (rhizosphere and pneumatophore) and bulk soil compartments. The rhizosphere but not pneumatophore soil compartment had significantly lower fungal species richness than bulk soil. However, bulk soil fungal diversity (Shannon diversity index) was significantly higher than both pneumatophore and rhizosphere soil compartments. The different soil compartments significantly affected the fungal community composition. Pairwise sample analyses showed that bulk soil microbial community composition significantly different from rhizosphere and pneumatophore soil compartments. There was, however no significant difference observed between rhizosphere and pneumatophore soil fungal community composition and they shared relatively more OTUs between them. Further, there was a significant correlation observed between fungal community compositional changes and carbon or nitrogen availability of different soil compartments. These results suggest that few characteristics such as fungal richness and taxa abundance of rhizosphere and pneumatophore soil compartments were significantly different in mangrove ecosystem.

    Mine effluents contain varying concentrations of ferrous ion along with other metal ions. Fe(II) that quickly oxidizes to form precipitates in the presence of oxygen under net alkaline or neutral conditions. Thus, passive treatment methods are designed for the mine water to reside in an open containment area so as to allow simultaneous oxidation and precipitation of Fe(II), such as in a lagoon or an oxidation pond. A vertical flow reactor (VFR) was also suggested to remediate ferruginous mine drainage passing down through an accreting bed of ochre. However, VFR has a limited operation time until the system begins to overflow. It was also demonstrated that two-compartment VFR has a longer operation time than single compartment VFR of same size. In this study, a mathematical model was developed as a part of efforts to explore the operation of VFR, showing dynamic changes in head differences, ochre depth and Fe(II)/Fe(III) concentration in the effluent flow. The analysis shows that Fe(II) oxidation and ochre formation should be balanced with permeability of ochre bed to maximize VFR operation time and minimize residual Fe(II) in the effluent. The model demonstrates that two compartment VFR can have a longer operation time than a single-compartment VFR and that an optimum compartment ratio exists that maximize VFR operation time. Accelerated Fe(II) oxidation significantly affects the optimum ratio of compartment area and reduced residual Fe(II) in the effluent. VFR operation time can be significantly prolonged by increasing the rate of ochre formation not by accelerated Fe(II) oxidation. Taken together, ochre forms largely in the first compartment while overflowed mine water with reduced iron contents is efficiently filtered in the second compartment. These results provide us a better understanding of VFR operation and optimum design criteria for maximum operation time in a two-compartment VFR. Rapid ochre accretion in the first compartment maintains constant hydraulic

    Low cardiac output syndrome remains a serious complication, and accounts for substantial morbidity and mortality in the postoperative course of paediatric patients undergoing surgery for congenital heart disease. Standard prophylactic and therapeutic strategies for low cardiac output syndrome are based mainly on catecholamines, which are effective drugs, but have considerable side effects. Levosimendan, a calcium sensitiser, enhances the myocardial function by generating more energy-efficient myocardial contractility than achieved via adrenergic stimulation with catecholamines. Thus potentially, levosimendan is a beneficial alternative to standard medication for the prevention of low cardiac output syndrome in paediatric patients after open heart surgery. To review the efficacy and safety of the postoperative prophylactic use of levosimendan for the prevention of low cardiac output syndrome and mortality in paediatric patients undergoing surgery for congenital heart disease. We identified trials via systematic searches of CENTRAL, MEDLINE, Embase, and Web of Science, as well as clinical trial registries, in June 2016. Reference lists from primary studies and review articles were checked for additional references. We only included randomised controlled trials (RCT) in our analysis that compared prophylactic levosimendan with standard medication or placebo, in infants and children up to 18 years of age, who were undergoing surgery for congenital heart disease. Two review authors independently extracted data and assessed risk of bias according to a pre-defined protocol. We obtained additional information from all but one of the study authors of the included studies. We used the five GRADE considerations (study limitations, consistency of effect, imprecision, indirectness, and publication bias) to assess the quality of evidence from the studies that contributed data to the meta-analyses for the prespecified outcomes. We created a 'Summary of findings' table to

    2006-01-01

    This paper describes a numerical model to study the behaviour of thermal comfort inside the passenger car compartment according to climatic conditions and materials that compose the vehicle. The specifically developed numerical model is based on the nodal method and the finite difference method. Its specificities are: (i) the transient mode, (ii) the taking into account of the combined convection, conduction and radiation heat transfer, (iii) the coupling of two spectral bands (short-wave and long-wave radiation) and two solar fluxes (beam and diffuse). The compartment is subdivided in several solid nodes (materials constituting the compartment) and fluid nodes (volumes of air inside the compartment). The establishment of the heat balance for each node gives the evolution of its temperature. Effects of solar radiation, types of glazing, car colour and radiative properties of materials constituting the compartment are investigated

    Fresh human cadavers provide an effective model for procedural training. Currently, there are no realistic models to teach fascial compartment pressure measurement. We created a human cadaver fascial compartment pressure measurement model and studied its feasibility with a pre-post design. Three faculty members, following instructions from a common procedure textbook, used a standard handheld intra-compartment pressure monitor (Stryker(®), Kalamazoo, MI) to measure baseline pressures ("unembalmed") in the anterior, lateral, deep posterior, and superficial posterior compartments of the lower legs of a fresh human cadaver. The right femoral artery was then identified by superficial dissection, cannulated distally towards the lower leg, and connected to a standard embalming machine. After a 5-min infusion, the same three faculty members re-measured pressures ("embalmed") of the same compartments on the cannulated right leg. Unembalmed and embalmed readings for each compartment, and baseline readings for each leg, were compared using a two-sided paired t-test. The mean baseline compartment pressures did not differ between the right and left legs. Using the embalming machine, compartment pressure readings increased significantly over baseline for three of four fascial compartments; all in mm Hg (±SD): anterior from 40 (±9) to 143 (±44) (p = 0.08); lateral from 22 (±2.5) to 160 (±4.3) (p measurable fascial compartment pressure measurement model in a fresh human cadaver using a standard embalming machine.

    AbstractDapsone is a bactericidal and bacteriostatic against Mycobacterium leprae , a causative agent of leprosy. Dapsone is also applied in a range of medical fields because of its anti-inflammatory and immunomodulatory effects. Dapsone hypersensitivity syndrome (DHS) is a rare yet serious adverse drug reaction (ADR) caused by dapsone involving multiple organs. We performed a systematic review of published articles describing dapsone-induced hypersensitivity syndrome, including all Chinese articles and the latest literature available in online databases published between October 2009 and October 2015. We determined the prevalence, clinical characteristics, and mortality rate of DHS. Importantly, we also summarized the recent advances in genetic testing allowing prediction of ADRs. In an initial systematic electronic search, we retrieved 191 articles. Subsequently, these articles were further filtered and ultimately 84 articles (60 Chinese case reports, 21 non-Chinese articles, and three epidemiological studies) were selected, which included 877 patients. The prevalence of DHS among Chinese patients was 1.5% with a fatality rate of 9.6%. Early withdrawal of dapsone and appropriate treatment reduced the fatality rate. Most importantly, genetic screening for the HLA-B*13:01 allele among high-risk populations showed a significant utility as a useful genetic marker to DHS. In conclusion, this review discusses the epidemiological and clinical characteristics of DHS among Chinese patients, which may help physicians to understand this syndrome.

    Prehospital care, including patient transport, is integral in the patient care process during the Ebola response. Transporting ill persons from the community to Ebola care facilities can stop community spread. Vehicles used for patient transport in infectious disease outbreaks should be evaluated for adequate infection prevention and control. An ambulance driver in Sierra Leone attributed his Ebola infection to exposure to body fluids that leaked from the patient compartment to the driver cabin of the ambulance. A convenience sample of 14 vehicles used to transport patients with suspected or confirmed Ebola in Sierra Leone were assessed. The walls separating the patient compartment and driver cabin in these vehicles were evaluated for structural integrity and potential pathways for body fluid leakage. Ambulance drivers and other staff were asked to describe their cleaning and decontamination practices. Ambulance construction and design standards from the National Fire Protection Association, US General Services Administration, and European Committee on Standardization (CEN) were reviewed. Many vehicles used by ambulance staff in Sierra Leone were not traditional ambulances, but were pick-up trucks or sport-utility vehicles that had been assembled or modified for patient transport. The wall separating the patient compartment and driver cabin in many vehicles did not have a waterproof seal around the edges. Staff responsible for cleaning and disinfection did not thoroughly clean bulk body fluids with disposable towels before disinfection of the patient compartment. Pressure from chlorine sprayers used in the decontamination process may have pushed body fluids from the patient compartment into the driver cabin through gaps around the wall. Ambulance design standards do not require a waterproof seal between the patient compartment and driver cabin. Sealing the wall by tightening or replacing existing bolts is recommended, followed by caulking of all seams with a

    Dementia is very common in Down syndrome (trisomy 21) adults. Statins may slow brain amyloid β (Aβ, coded on chromosome 21) deposition and, therefore, delay Alzheimer disease onset. One prospective cohort study with Down syndrome adults found participants on statins had reduced risk of incident dementia, but there are no randomised controlled trials (RCTs) on this issue. Evidence is sparse on the best instruments to detect longitudinal cognitive decline in older Down syndrome adults. TOP-COG was a feasibility/pilot, double-blind RCT of 12 months simvastatin 40 mg versus placebo for the primary prevention of dementia in Alzheimer disease in Down syndrome adults aged 50 years or older. Group allocation was stratified by age, apolipoprotein E (APOE) ε4 allele status, and cholesterol level. Recruitment was from multiple general community sources over 12 months. Adults with dementia, or simvastatin contraindications, were excluded. Main outcomes were recruitment and retention rates. Cognitive decline was measured with a battery of tests; secondary measures were adaptive behaviour skills, general health, and quality of life. Assessments were conducted pre randomisation and at 12 months post randomisation. Blood Aβ40/Aβ42 levels were investigated as a putative biomarker. Results were analysed on an intention-to-treat basis. A qualitative sub-study was conducted and analysed using the Framework Approach to determine recruitment motivators/barriers, and participation experience. We identified 181 (78 %) of the likely eligible Down syndrome population, and recruited 21 (11.6 %), from an area with a general population size of 3,135,974. Recruitment was highly labour-intensive. Thirteen (62 %) participants completed the full year. Results favoured the simvastatin group. The most appropriate cognitive instrument (regarding ease of completion and detecting change over time) was the Memory for Objects test from the Neuropsychological Assessment of Dementia in

    2016-07-01

    Full Text Available The harmful effects of particulate matter with an aerodynamic diameter of <2.5 µm (PM2.5 and its association with acute coronary syndrome (ACS has gained increased attention in recent years. Significant associations between PM2.5 and ACS have been found in most studies, although sometimes only observed in specific subgroups. PM2.5-induced detrimental effects and ACS arise through multiple mechanisms, including endothelial injury, an enhanced inflammatory response, oxidative stress, autonomic dysfunction, and mitochondria damage as well as genotoxic effects. These effects can lead to a series of physiopathological changes including coronary artery atherosclerosis, hypertension, an imbalance between energy supply and demand to heart tissue, and a systemic hypercoagulable state. Effective strategies to prevent the harmful effects of PM2.5 include reducing pollution sources of PM2.5 and population exposure to PM2.5, and governments and organizations publicizing the harmful effects of PM2.5 and establishing air quality standards for PM2.5. PM2.5 exposure is a significant risk factor for ACS, and effective strategies with which to prevent both susceptible and healthy populations from an increased risk for ACS have important clinical significance in the prevention and treatment of ACS.

  6. Stochastic Turing Patterns: Analysis of Compartment-Based Approaches

    KAUST Repository

    Cao, Yang

    2014-11-25

    © 2014, Society for Mathematical Biology. Turing patterns can be observed in reaction-diffusion systems where chemical species have different diffusion constants. In recent years, several studies investigated the effects of noise on Turing patterns and showed that the parameter regimes, for which stochastic Turing patterns are observed, can be larger than the parameter regimes predicted by deterministic models, which are written in terms of partial differential equations (PDEs) for species concentrations. A common stochastic reaction-diffusion approach is written in terms of compartment-based (lattice-based) models, where the domain of interest is divided into artificial compartments and the number of molecules in each compartment is simulated. In this paper, the dependence of stochastic Turing patterns on the compartment size is investigated. It has previously been shown (for relatively simpler systems) that a modeler should not choose compartment sizes which are too small or too large, and that the optimal compartment size depends on the diffusion constant. Taking these results into account, we propose and study a compartment-based model of Turing patterns where each chemical species is described using a different set of compartments. It is shown that the parameter regions where spatial patterns form are different from the regions obtained by classical deterministic PDE-based models, but they are also different from the results obtained for the stochastic reaction-diffusion models which use a single set of compartments for all chemical species. In particular, it is argued that some previously reported results on the effect of noise on Turing patterns in biological systems need to be reinterpreted.

    We report a case of a 36-year old patient with prior history of thrombosis in a setting of antiphospholipid antibody syndrome (APS) as well as pregnancy-associated catastrophic antiphospholipid syndrome (CAPS), resulting in multi-organ infarction and pregnancy loss. The episode of CAPS occurred while she was receiving antepartum low-dose aspirin and therapeutic-dose enoxaparin. This patient presented again at 6 weeks gestation and ultrasounds were consistent with fetal growth restriction, concerning for placental insufficiency and thrombosis. This time, hydroxychloroquine and monthly intravenous immunoglobulin (IVIG) infusions were added to her prophylaxis regimen, resulting in a successful delivery. Platelet count and antiphospholipid antibody titers were routinely monitored throughout pregnancy as markers of disease activity for APS. Current thromboprophylaxis guidelines do not address therapeutic options to prevent further pregnancy morbidity in women who develop recurrent episodes of thrombosis or CAPS despite receiving adequate anti-thrombotic treatment. Use of hydroxychloroquine and IVIG has been associated with good outcomes in this subset of patients.

    Anti-inflammatory glucocorticoid (GC) therapy often induces hyperglycemia due to insulin resistance and islet-cell dysfunction. Incretin-based therapies may preserve glucose tolerance and pancreatic islet-cell function. In this study, we hypothesized that concomitant administration of the dipeptidyl peptidase-4 inhibitor sitagliptin and prednisolone in men at high risk to develop type 2 diabetes could protect against the GC-induced diabetogenic effects. Men with the metabolic syndrome but without diabetes received prednisolone 30  mg once daily plus sitagliptin 100  mg once daily (n=14), prednisolone (n=12) or sitagliptin alone (n=14) or placebo (n=12) for 14 days in a double-blind 2 × 2 randomized-controlled study. Glucose, insulin, C-peptide, and glucagon were measured in the fasted state and following a standardized mixed-meal test. β-cell function parameters were assessed both from a hyperglycemic-arginine clamp procedure and from the meal test. Insulin sensitivity (M-value) was measured by euglycemic clamp. Prednisolone increased postprandial area under the curve (AUC)-glucose by 17% (P<0.001 vs placebo) and postprandial AUC-glucagon by 50% (P<0.001). Prednisolone reduced 1st and 2nd phase glucose-stimulated- and combined hyperglycemia-arginine-stimulated C-peptide secretion (all P ≤ 0.001). When sitagliptin was added, both clamp-measured β-cell function (P=NS for 1st and 2nd phase vs placebo) and postprandial hyperglucagonemia (P=NS vs placebo) remained unaffected. However, administration of sitagliptin could not prevent prednisolone-induced increment in postprandial glucose concentrations (P<0.001 vs placebo). M-value was not altered by any treatment. Fourteen-day treatment with high-dose prednisolone impaired postprandial glucose metabolism in subjects with the metabolic syndrome. Concomitant treatment with sitagliptin improved various aspects of pancreatic islet-cell function, but did not prevent deterioration of glucose tolerance by GC treatment.

    Insulin resistance, obesity, hypertension, and dyslipidemia are strongly associated with metabolic syndrome (MeSy), which is considered to be a reversible clinical stage before its evolution to coronary heart disease and diabetes. Currently, the antihypertensive and hypolipidemic properties of aqueous Hibiscus sabdariffa extracts (HSE) have been demonstrated in clinical trials and in vivo experiments. The aim of the present study was to evaluate the effects of a Hibiscus sabdariffa extract powder (HSEP) and a recognized preventive treatment (diet) on the lipid profiles of individuals with and without MeSy according to the National Cholesterol Education Program Adult Treatment Panel III (NCEP-ATP III) criteria. The protocol was a follow-up study carried out in a factorial, randomized design (T1=preventive treatment comprises Diet, T2=HSEP, T3=HSEP+preventive treatment (Diet) X MeSy, non-MeSy individuals). A total daily dose of 100 mg HSEP was orally administered in capsules for one month. The preventive treatment (diet) was selected according to NCEP-ATP III recommendations and adjusted individually. Total cholesterol, LDL-c, HDL-c, VLDL-c, triglycerides, glucose, urea, creatinine, AST, and ALT levels in the blood were determined in all individuals pre- and post-treatment. The MeSy patients treated with HSEP had significantly reduced glucose and total cholesterol levels, increased HDL-c levels, and an improved TAG/HDL-c ratio, a marker of insulin resistance (t-test pHibiscus sabdariffa, we suggest the use of HSEP in individuals with dyslipidemia associated with MeSy.

    Ovarian hyperstimulation syndrome (OHSS) is an iatrogenic and potentially life-threatening disease process, which may occur in healthy young women undergoing controlled ovarian hyperstimulation for assisted reproduction. As the treatment is largely empirical, prevention forms the mainstay of management. The present study was aimed to evaluate the effectiveness of intravenous (IV) calcium gluconate infusion in comparison to the dopamine agonist cabergoline (Cb2) in preventing OHSS in high risk patients undergoing assisted reproductive technique cycles. It was a comparative study wherein the 202 high risk patients undergoing in vitro-fertilization over a period of 18 months after meeting the strict inclusion and the exclusion criteria, were randomly divided into two groups (98 subjects in Group I and 104 in Group II). Women in Group I were administered IV calcium gluconate while the remaining 104 received the dopamine agonist Cb2. The 104 patients belonging to Group II were started Cb2 0.5 mg/day from the day of ovulation trigger and continued until the next 8 days while the 98 high risk patients from Group I were infused with 10 ml of 10% calcium gluconate solution in 200 ml physiologic saline within 30 min of ovum pick up and continued thereafter on day 1, day 2 and day 3. The occurrence of OHSS was seen in only nine patients (in the calcium infusion group, when compared with 16 patients (9.2% vs. 15.4%) who were administered Cb2, but it was not statistically significant. However, only one had severe OHSS in Group I, whereas two women were diagnosed as severe OHSS belonging to the Cb2 arm. Our results document that calcium infusion can effectively prevent severe OHSS and decreases OHSS occurrence rates when used for high-risk patients, but does not suggest its superiority over Cb2. With comparable success rates, either of them can be employed as a preventive strategy for OHSS.

    The human immunodeficiency virus type 1 (HIV-1) envelope glycoprotein (Env) encodes specific trafficking signals within its long cytoplasmic tail (CT) that regulate incorporation into HIV-1 particles. Rab11-family interacting protein 1C (FIP1C) and Rab14 are host trafficking factors required for Env particle incorporation, suggesting that Env undergoes sorting from the endosomal recycling compartment (ERC) to the site of particle assembly on the plasma membrane. We disrupted outward sorting from the ERC by expressing a C-terminal fragment of FIP1C (FIP1C 560-649 ) and examined the consequences on Env trafficking and incorporation into particles. FIP1C 560-649 reduced cell surface levels of Env and prevented its incorporation into HIV-1 particles. Remarkably, Env was trapped in an exaggerated perinuclear ERC in a CT-dependent manner. Mutation of either the Yxxϕ endocytic motif or the YW 795 motif in the CT prevented Env trapping in the ERC and restored incorporation into particles. In contrast, simian immunodeficiency virus SIVmac239 Env was not retained in the ERC, while substitution of the HIV-1 CT for the SIV CT resulted in SIV Env retention in this compartment. These results provide the first direct evidence that Env traffics through the ERC and support a model whereby HIV-1 Env is specifically targeted to the ERC prior to FIP1C- and CT-dependent outward sorting to the particle assembly site on the plasma membrane. IMPORTANCE The HIV envelope protein is an essential component of the viral particle. While many aspects of envelope protein structure and function have been established, the pathway it follows in the cell prior to reaching the site of particle assembly is not well understood. The envelope protein has a very long cytoplasmic tail that interacts with the host cell trafficking machinery. Here, we utilized a truncated form of the trafficking adaptor FIP1C protein to arrest the intracellular transport of the envelope protein, demonstrating that it becomes

    The increasing incidence and prevalence of metabolic syndrome and type 2 diabetes mellitus (DM) have significant implications on health world-wide. Large clinical trials have demonstrated the effectiveness of a comprehensive lifestyle program with a goal of moderate weight loss (5-7%) and regular exercise (150 minutes/week), resulting in a significant decrease in the incidence of type 2 DM and cardiovascular risk. This study reports on the translation of the multi-center Diabetes Prevention Program (DPP) into a cardiac rehabilitation program, utilizing the expertise and experience of a cardiac rehabilitation program staff. The study adapted materials from the DPP to develop a program that fit local needs for diabetes prevention. Most participants completed the program (11 months) and their moderate weight loss was maintained for 11-12 months. At 11-12 months, waist circumference was reduced by approximately 2 inches, percent body fat was reduced by 5% (11% relative decrease, pExercise, nutrition, glucose, triglycerides, LDL-cholesterol and HDL cholesterol were all were significantly improved at 11-12 months (pdiabetes. This program demonstrates that an intensive effort can significantly improve lifestyle and reduce body weight in patients with DM or at risk for DM. A program that simulates cardiac rehabilitation, translated from a successful clinical trial into practice, resulted in significant reduction and improvement in metabolic outcomes and cardiovascular risk. Support for cardiac rehabilitation from insurers to develop similar programs is encouraged and deserves further study.

    A vertical flow reactor (VFR) has been suggested for remediation of ferruginous mine drainage that passes down through an accreting bed of ochre. However, a VFR has a limited operation time until the system begins to overflow. In this study, a mathematical model was developed as a part of the effort to explore the operation of a VFR, showing dynamic changes in the head differences, ochre depths, and Fe(II)/Fe(III) concentrations in the effluent flow. The analysis showed that VFR operation time extended from 148.5 days to 163 days in an equally divided and to 168.4 days in asymmetrically (0.72:0.28) divided two-compartment VFR, suggesting that an optimum compartment ratio exists that maximizes the VFR operation time. A constant head filtration in the first compartment maximized filtration efficiency and thus prolonged VFR longevity in the two-compartment VFR. Fe(II) oxidation and ochre formation should be balanced with the permeability of the ochre bed to maximize the VFR operation time and minimize the residual Fe(II) in the effluent. Accelerated Fe(II) oxidation affected the optimum ratio of the compartment area and reduced the residual Fe(II) in the effluent. The VFR operation time can be prolonged significantly from 764 days to 3620 days by increasing the rate of ochre formation, much more than by accelerating the Fe(II) oxidation. During the prolonged VFR operation, ochre formed largely in the first compartment, while overflowing mine water with reduced iron content was effectively filtered in the second compartment. These results not only provide a better understanding of VFR operation but also suggest the direction of evolution of two-compartment VFR toward a compact and highly efficient facility integrated with an aerated cascade and with automatic coagulant feeding.

    Fowl adenovirus-4 is an infectious agent causing Hydropericardium syndrome in chickens. Adenovirus are non-enveloped virions having linear, double stranded DNA. Viral genome codes for few structural and non structural proteins. 100K is an important non-structural viral protein. Open reading frame for coding sequence of 100K protein was cloned with oligo histidine tag and expressed in Escherichia coli as a fusion protein. Nucleotide sequence of the gene revealed that 100K gene of FAdV-4 has high homology (98%) with the respective gene of FAdV-10. Recombinant 100K protein was expressed in E. coli and purified by nickel affinity chromatography. Immunization of chickens with recombinant 100K protein elicited significant serum antibody titers. However challenge protection test revealed that 100K protein conferred little protection (40%) to the immunized chicken against pathogenic viral challenge. So it was concluded that 100K gene has 2397 bp length and recombinant 100K protein has molecular weight of 95 kDa. It was also found that the recombinant protein has little capacity to affect the immune response because in-spite of having an important role in intracellular transport & folding of viral capsid proteins during viral replication, it is not exposed on the surface of the virus at any stage.

    To define infant care practices in maternity units and those subsequently adopted at home. Using these data, we evaluated the acceptance and application of recommendations issued by the previous public education campaign on infant sleeping position as related to sudden infant death syndrome. A survey was carried out in two maternity units (Port-Royal and Créteil) and in one pediatric consultation unit (affiliated with Port-Royal maternity). The mixed position (side or back) is used equally with, respectively, 47% at Port-Royal and 45% at Créteil. The supine sleeping position (French public health recommendations) is used by 12% of the mothers at Port-Royal and by 40% at Créteil. It appears that hospital nurseries play an important role in determining the mother's preference for the sleeping position (64% at Port-Royal and 54% at Créteil), but it does not adequately explain all mothers' responses. However, as the infants mature (> two months old), the more spontaneously they changed their sleeping position. All the infants placed in a side sleeping position moved to a supine sleeping position during the night. Upon awakening, infants were found mostly in the supine position (in contrast to the national public education campaign). Our results show that mothers and hospital nurseries were distressed in terms of ensuring the supine sleeping position of the infant. New choices of sleeping positions were initiated by mothers. For example, they used the side position after feedings essentially in the case of reflux or during the daytime. The supine position was used when the mothers were assured that any problems had been avoided or only during the night.

    Full Text Available Background/Aim. The occurrence of atrial fibrillation (AF in the presence of an accessory pathway (AP that conducts rapidly is potentially lethal because the rapid ventricular response may lead to ventricular fibrillation (VF. The aim of the study was to determine long-term efficacy of AP catheter-ablation using radiofrequency (RF current in secondary prevention of VF in WPW patients. Methods. Study included a total of 192 symptomatic WPW patients who underwent RF catheter-ablation of AP in our institution from 1994 to 2007 and were available for clinical follow-up for more than 3 months after procedure. Results. Before ablation, VF was recorded in total of 27 patients (14.1%. In 14 of patients (51.9% VF was the first clinical manifestation of WPW syndrome. A total of 35 VF episodes were identified in 27 patients. The occurrence of VF was preceded by physical activity or emotional stress in 17.1% of cases, by alcohol abuse in 2.9% and by inappropriate intravenous drug administration in 28.6%. In addition, no clear precipitating factor was identified in 40% of VF cases, while informations about activities preceding 11.4% of VF episodes were not available. The follow-up of 5.7 ± 3.3 years was obtained in all of 27 VF patients. Of the 20 patients who underwent successful AP ablation, all were alive, without syncope or ventricular tachyarrhythmias during long-term follow-up. In 4 of 7 unsuccessfully treated patients, recurrence of supraventricular tachycardia and/or preexcited atrial fibrillation were recorded; one of these patients suddenly died of VF, 6 years after procedure. Conclusion. In significant proportion of WPW patients, VF was the first clinical manifestation of WPW syndrome, often precipitated by physical activity, emotional stress or inappropriate drug administration. Successful elimination of AP by percutaneous RF catheter-ablation is highly effective in secondary prevention of life-threatening tachyarrhythmias in patients with

    The cholesterol content of membranes plays an important role in organizing membranes for signal transduction and protein trafficking as well as in modulating the biophysical properties of membranes. While the properties of model or isolated membranes have been extensively studied, there has been little evaluation of internal membranes in living cells. Here, we use a Nile Red based probe, NR12S, and ratiometric live cell imaging, to analyze the membrane order of the plasma membrane and endocytic recycling compartment. We find that after a brief incubation to allow endocytosis, NR12S is distributed between the plasma membrane and the endocytic recycling compartment. The NR12S reports that the endocytic recycling compartment is more highly ordered than the plasma membrane. We also find that the plasma membrane and the endocytic recycling compartment are differentially affected by altering cellular cholesterol levels. The membrane order of the plasma membrane, but not the endocytic recycling compartment, is altered significantly when cellular cholesterol content is increased or decreased by 20%. These results demonstrate that changes in cellular cholesterol differentially alter membrane order within different organelles.

    SLC26A4 mutations cause fluctuating and progressive hearing loss associated with enlargement of the vestibular aqueduct (EVA). SLC26A4 encodes a transmembrane anion exchanger called pendrin expressed in nonsensory epithelial cells of the lateral wall of cochlea, vestibular organs and endolymphatic sac. We previously described a transgenic mouse model of EVA with doxycycline (dox)-inducible expression of Slc26a4 in which administration of dox from conception to embryonic day 17.5 (DE17.5) resulted in hearing fluctuation between 1 and 3months of age. In the present study, we hypothesized that Slc26a4 is required to stabilize hearing in DE17.5 ears between 1 and 3months of age. We tested our hypothesis by evaluating the effect of postnatal re-induction of Slc26a4 expression on hearing. Readministration of dox to DE17.5 mice at postnatal day 6 (P6), but not at 1month of age, resulted in reduced click-evoked auditory brainstem response (ABR) thresholds, less fluctuation of hearing and a higher surface density of pendrin expression in spindle-shaped cells of the stria vascularis. Pendrin expression in spindle-shaped cells was inversely correlated with ABR thresholds. These findings suggest that stabilization of hearing by readministration of dox at P6 is mediated by pendrin expression in spindle-shaped cells. We conclude that early re-induction of Slc26a4 expression can prevent fluctuation of hearing in our Slc26a4-insufficient mouse model. Restoration of SLC26A4 expression and function could reduce or prevent fluctuation of hearing in EVA patients. Published by Elsevier Ltd.

    The present study aimed to study the effects of exercise training (ET) performed by rats on a 10-week high-fructose diet on metabolic, hemodynamic, and autonomic changes, as well as intraocular pressure (IOP). Male Wistar rats receiving fructose overload in drinking water (100 g/L) were concomitantly trained on a treadmill for 10 weeks (FT group) or kept sedentary (F group), and a control group (C) was kept in normal laboratory conditions. The metabolic evaluation comprised the Lee index, glycemia, and insulin tolerance test (KITT). Arterial pressure (AP) was measured directly, and systolic AP variability was performed to determine peripheral autonomic modulation. ET attenuated impaired metabolic parameters, AP, IOP, and ocular perfusion pressure (OPP) induced by fructose overload (FT vs F). The increase in peripheral sympathetic modulation in F rats, demonstrated by systolic AP variance and low frequency (LF) band (F: 37±2, 6.6±0.3 vs C: 26±3, 3.6±0.5 mmHg{sup 2}), was prevented by ET (FT: 29±3, 3.4±0.7 mmHg{sup 2}). Positive correlations were found between the LF band and right IOP (r=0.57, P=0.01) and left IOP (r=0.64, P=0.003). Negative correlations were noted between KITT values and right IOP (r=-0.55, P=0.01) and left IOP (r=-0.62, P=0.005). ET in rats effectively prevented metabolic abnormalities and AP and IOP increases promoted by a high-fructose diet. In addition, ocular benefits triggered by exercise training were associated with peripheral autonomic improvement.

    The present study aimed to study the effects of exercise training (ET) performed by rats on a 10-week high-fructose diet on metabolic, hemodynamic, and autonomic changes, as well as intraocular pressure (IOP). Male Wistar rats receiving fructose overload in drinking water (100 g/L) were concomitantly trained on a treadmill for 10 weeks (FT group) or kept sedentary (F group), and a control group (C) was kept in normal laboratory conditions. The metabolic evaluation comprised the Lee index, glycemia, and insulin tolerance test (KITT). Arterial pressure (AP) was measured directly, and systolic AP variability was performed to determine peripheral autonomic modulation. ET attenuated impaired metabolic parameters, AP, IOP, and ocular perfusion pressure (OPP) induced by fructose overload (FT vs F). The increase in peripheral sympathetic modulation in F rats, demonstrated by systolic AP variance and low frequency (LF) band (F: 37±2, 6.6±0.3 vs C: 26±3, 3.6±0.5 mmHg 2 ), was prevented by ET (FT: 29±3, 3.4±0.7 mmHg 2 ). Positive correlations were found between the LF band and right IOP (r=0.57, P=0.01) and left IOP (r=0.64, P=0.003). Negative correlations were noted between KITT values and right IOP (r=-0.55, P=0.01) and left IOP (r=-0.62, P=0.005).

    The osmotic demyelination syndrome (ODS) has been identified as a complication of the rapid correction of hyponatremia for decades. However, in recent years, a variety of other medical conditions have been associated with the development of ODS, independent of changes in serum sodium which cause a rapid changes in osmolality of the interstitial (extracellular) compartment of the brain leading to dehydration of energy-depleted cells with subsequent axonal damage that occurs in characteristic areas. Slow correction of the serum sodium concentration and additional administration of corticosteroids seems to be a major prevention step in ODS patients. In the current report we aimed to share a rare case which we observed in our hospital. A 65 year old female admitted as altered sensorium with history of vomiting, diarrhea was managed with intravenous fluids for 2 days at a peripheral health centre. Patient was referred to our centre with encephalopathy, evaluated and found to have hyponatremia and hypokalemia rest of biochemical parameters and septic profile were normal. Patient's electrolyte disturbances were managed as per guidelines but encephalopathy persisted. Supportive treatment was continued and patient was discharged after 2 wks of stay in hospital after gaining full sensorium and neurological functions.

    Documentation of the psittacine paranasal sinuses has been limited. To provide more published detail, spiral computed tomography (CT) was used to scan the cephalic and cervical region from cadavers of 10 psittacine birds (Ara ararauna, Ara chloroptera, Ara macao, and Anodorhynchus hyacinthinus). Skeletal studies, histologic examinations, and evaluation of deep-frozen sections and anatomic preparations confirmed the results of the CT scans. New morphologic details of the paranasal sinus and some compartments were discovered. The paranasal sinuses of these macaws consist of two unpaired rostral compartments, followed caudally by eight paired compartments. Histologic examinations revealed that the walls of the paranasal sinuses consist of flat or cubic monolayer epithelium with underlying connective tissue. The described method of CT examination of these macaws, especially the positioning, scan orientation and parameters, and documentation of the normal paranasal sinus, provides a basis for future clinical use of CT.

    Transmission of Middle East respiratory syndrome-coronavirus (MERS-CoV) among health care workers (HCWs) and patients has been documented with mortality rate approximating 36%. We propose advanced infection control measures (A-IC) used in conjunction with basic infection control measures (B-IC) help reduce pathogen transmission. B-IC include standard and transmission-based precautions. A-IC are initiatives implemented within our center to enhance effectiveness of B-IC. Study effectiveness of combining B-IC and A-IC to prevent transmission of MERS-CoV to HCWs. A retrospective observational study was undertaken. A-IC measures include administrative support with daily rounds; infection control risk assessment; timely screening, isolation, and specimen analysis; collaboration; epidemic planning; stockpiling; implementation of contingency plans; full personal protective equipment use for advanced airway management; use of a real-time electronic isolation flagging system; infection prevention and control team on-call protocols; pretransfer MERS-CoV testing; and education. A total of 874 real-time polymerase chain reaction MERS-CoV tests were performed during the period beginning July 1, 2013, and ending January 31, 2015. Six hundred ninety-four non-HCWs were tested, of these 16 tested positive for MERS-CoV and their infection was community acquired. Sixty-nine percent of the confirmed MERS-CoV-positive cases were men, with an average age of 56 years (range, 19-84 years). Of the total tested for MERS-CoV, 180 individuals were HCWs with zero positivity. Adhering to a combination of B-IC and A-IC reduces the risk of MERS-CoV transmission to HCWs.

    Acute coronary syndrome (ACS) is a major cause of death from a non-communicable disease. Secondary prevention is effective for reducing morbidity and mortality, but evidence-based targets are seldom reached and new interventional methods are needed. The present study is a feasibility study of a telephone-based secondary preventive programme in an unselected ACS cohort. The NAILED (Nurse-based Age-independent Intervention to Limit Evolution of Disease) ACS trial is a prospective randomized controlled trial. All eligible patients admitted for ACS were randomized to usual follow-up by a general practitioner or telephone follow-up by study nurses. The intervention was made by continuous telephone contact, with counseling on healthy living and titration of medicines to reach target values for blood pressure and blood lipids. Exclusion criteria were limited to physical inability to follow the study design or participation in another study. A total of 907 patients were assessed for inclusion. Of these, 661 (72.9%) were included and randomized, 100 (11%) declined participation, and 146 (16.1%) were excluded. The main reasons for exclusion were participation in another trial, dementia, and advanced disease. "Excluded" and "declining" patients were significantly older with more co-morbidity, decreased functional status, and had more seldom received education above compulsory school level than "included" patients. Non-participants had a higher 1-year mortality than participants. Nurse-led telephone-based follow-up after ACS can be applied to a large proportion in an unselected clinical setting. Reasons for non-participation, which were associated with increased mortality, include older age, multiple co-morbidities, decreased functional status and low level of education.

    Full Text Available Background: The high consumption of fat and sugar contributes to the development of obesity and co-morbidities, such as diabetes, and cardiovascular and kidney diseases. Different strategies have been used to prevent these diseases associated with obesity, such as changes in eating habits and/or the addition of dietary components with anti-inflammatory and anti-oxidant properties, such as gamma-oryzanol (γOz present mainly in bran layers and rice germ. Methods: Animals were randomly divided into four experimental groups and fed ad libitum for 20 weeks with control diet (C, n = 8, control diet + γOz (C + γOz, n = 8, high-sugar and high-fat diet (HSF, n = 8, and high-sugar and high-fat diet + γOz (HSF + γOz, n = 8. HSF groups also received water + sucrose (25%. The dose of γOz was added to diets to reach 0.5% of final concentration (w/w. Evaluation in animals included food and caloric intake, body weight, plasma glucose, insulin, triglycerides, uric acid, HOMA-IR, glomerular filtration rate, protein/creatinine ratio, systolic blood pressure, and Doppler echocardiographic. Results: Animals that consumed the HSF diet had weight gain compared to group C, increased insulin, HOMA, glucose and triglycerides, there were also atrial and ventricular structural alterations, deterioration of systolic and diastolic function, decreased glomerular filtration rate, and proteinuria. Gamma-oryzanol is significantly protective against effects on body weight, hypertriglyceridemia, renal damage, and against structural and functional alteration of the heart. Conclusion: Gamma-oryzanol shows potential as a therapeutic to prevent Cardiorenal Metabolic Syndrome.

    Background The prevalence of metabolic syndrome is high and is increasing in parallel with increasing incidences of breast and prostate cancers. The combination of soy with tea was shown to have synergistic effects on preventing breast and prostate tumors, but the effects of soy and tea combinations on metabolic syndrome–related elements have not been investigated. Objective We aimed to determine the effects of soy and tea components, alone and in combination, on abdominal adipose mass and serum concentrations of adipokines, growth factors, and sex hormones in male and female mice. Design Male and female FVB/N mice were treated with soy, tea components, or both. Food intake and body weight were monitored weekly. At the end of the experiment, abdominal white adipose tissue was weighed, and serum concentrations of biomarkers were measured. Results Whole teas, but not the tea polyphenol extracts, significantly reduced abdominal white adipose tissue by 43–60% in female mice and by 65–70% in male mice. The combination of soy phytochemical concentrate and green tea reduced serum insulin-like growth factor-I concentrations in both male and female mice in a synergistic manner. The soy phytochemical concentrate and tea combinations reduced serum estrogen concentrations in female mice in a synergistic manner. Soy phytochemical concentrate and teas also significantly reduced serum leptin concentrations in both male and female mice and testosterone concentrations in male mice. Conclusion Further research is warranted to investigate whether soy and tea combinations may prevent breast or prostate cancer in a synergistic manner in part by alleviating metabolic disorders.

  20. Premature loss of bone remodeling compartment canopies is associated with deficient bone formation

    DEFF Research Database (Denmark)

    Jensen, Pia Rosgaard; Andersen, Thomas Levin; Søe, Kent

    2011-01-01

    A remarkable property of bone remodeling is that osteoblasts form bone matrix exactly where and when osteoclasts have removed it. The bone remodeling compartment (BRC) canopies that cover bone surfaces undergoing remodeling, were proposed to be critical players in this mechanism. Here, we provide...... support to this hypothesis by analyzing the changes in prevalence of BRC canopies during the progress of the remodeling cycle in a cohort of healthy individuals and in patients with endogenous Cushing's syndrome (CS), and by relating these changes in prevalence with the extent of bone forming surfaces....... Both cohorts showed almost 100% canopy coverage above resorbing osteoclasts, and only about 76% above bone forming surfaces. This indicates that BRC canopies are invariably associated with the early stage of the remodeling cycle, but may disappear later. Interestingly, in control and two thirds...

    Histone deacetylase inhibitors (HDACI) are members of a family of epigenetic modifying agents with broad anti-inflammatory properties. These anti-inflammatory properties may have important therapeutic implications in acute respiratory distress syndrome (ARDS). However, administration of HDACI may create an immunosuppressive environment conducive to bacterial growth. Accordingly, the aim of the current study is to investigate the effect of HDACI valproic acid (VPA) on host inflammatory response and bacterial burden in a murine model of Escherichia coli pneumonia-induced ARDS. ARDS was induced in male C57BL6 mice (n = 24) by endotracheal instillation of 3 × 10 E. coli. VPA (250 mg/kg) was administered 30 minutes after E. coli instillation in the intervention group. Blood samples were collected at 3 and 6 hours, and animals were sacrificed at 6 hours. Bronchoalveolar lavage (BAL) was performed, and tissue specimens were harvested. Cytokine levels were measured in blood and BAL, and so was transalveolar protein transit. Cell counts and colony forming units were quantified in BAL fluid. VPA reduced neutrophil influx into the lungs and local tissue destruction through decreased myeloperoxidase activity. It also ameliorated the pulmonary and systemic inflammatory response. This led to greater bacterial proliferation in the pulmonary parenchyma. Administration of VPA in a clinically relevant bacterial model of murine ARDS mitigates the host inflammatory response, essentially preventing ARDS, but creates an immunosuppressive environment that favors bacterial overgrowth.

    Since 1996, the number of reports in the urologic and gynecologic literature using synthetic and allograph prosthetics to enhance the durability of anterior compartment repairs have increased significantly. Central to the use of these prosthetics is long-term follow-up to demonstrate that their use actually confers a benefit to patients and surgeons alike. This review attempts to catalog those reports and the outcomes, with an emphasis on the cadaveric prolapse repair with sling, which is used by the authors for repair of anterior compartment prolapse with overt or occult genuine stress urinary incontinence.

    CD1 molecules are glycoproteins present primarily on dendritic cells (DCs), which recognize and present a variety of foreign- and self-lipid antigens to T-cells. Humans have five different CD1 isoforms that survey distinct cellular compartments allowing for recognition of a large repertoire of lipids. The canine CD1 family consists of seven functional CD1 molecules (canine CD1a2, CD1a6, CD1a8, CD1a9, CD1b, CD1c and CD1e) and one presumed non-functional isoform (canine CD1d) due to a disrupted gene structure. The aim of this study was to describe in vitro steady-state localization ptterns of canine CD1 isoforms and their correlation with endocytic organelles. GFP-fused canine CD1 293T cell transfectants were stained with markers for early endocytic compartments (EEA-1) and late endocytic/lysosomal compartments (LAMP-1), respectively, and analyzed by confocal microscopy. Canine CD1a molecules localized to the plasma membrane and partially to the early endocytic compartment, but not to late endosomes or lysosomes. In contrast, canine CD1b was highly associated with late endosomal/lysosomal compartments and showed a predominant intracellular expression pattern. Canine CD1c protein expression localized more promiscuously to both the early endosomal compartments and the late endosomal/lysosomal compartments. The canine CD1e molecule showed a strictly intracellular expression with a partial overlap with late endosomal/lysosomal compartments. Lastly, canine CD1d was expressed abnormally showing only a diminished GFP expression. In conclusion, canine CD1 transfectants show distinct localization patterns that are similar to human CD1 proteins with the exception of the canine CD1d isoform, which most likely is non-functional. These findings imply that canine CD1 localization overall resembles human CD1 trafficking patterns. This knowledge is important for the understanding of lipid antigen-receptor immunity in the dog.

    2015-11-01

    To evaluate the efficacy of myo-inositol (MI) pretreatment in OHSS. In this experimental OHSS rat model, 42 immature Wistar albino female rats were divided into 6 groups: (1) the control group, (2) the ovarian stimulation group, (3) the OHSS group, (4) the OHSS + Metformin group, (5) OHSS + MI group, (6) OHSS + Metformin + MI group. OHSS was established after treatment with metformin and myo-inositol for 14 days, in the meanwhile the treatment of metformin and myo-inositol was also continued. All animals were killed 48 h after hCG administration and were compared in terms of vascular permeability, ovarian weight and diameter, ovarian VEGF, COX-2 and PEDF expression (immunohistochemistry), serum PEDF and estradiol (E2) levels. Vascular permeability, VEGF and COX-2 expressions were reduced in animals treated with MI and/or metformin. While PEDF expression was increased in the groups taking metformin, there was no difference in PEDF expression in the group taking MI and OHSS group. There was no significant difference in serum PEDF levels between groups. Blood E2 levels were decreased in groups treated with MI or metformin compared to the OHSS group. Our data demonstrate that myo-inositol is effective in preventing OHSS, similar to metformin. Although the two drugs are thought to act through distinct mechanisms, there is no apparent benefit to co-treatment with both drugs in an animal model of OHSS. Administration of myo-inositol prior to IVF treatment may favor the control of ovulation induction. Further studies are necessary to elucidate the mechanism of action and further support our findings.

    Guidelines regarding the impact and value of prophylaxis or maintenance therapy in Equine Gastric Ulcer Syndrome (EGUS) are not well established or defined. The merits and the magnitude of effects of prophylaxis for spontaneous or recurrent squamous gastric ulceration in horses in training are uncertain. To pool data from randomised controlled trials (RCTs) to eliminate reporting bias and evaluate the efficacy of prophylactic omeprazole in the prevention of EGUS in training horses, and secondarily to compare prophylactic dosages of omeprazole. Meta-analysis. This meta-analysis was conducted according to the recommendations of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. A systematic literature search identified RCTs comparing omeprazole prophylaxis with sham in prevention of EGUS. Data were analysed using the Mantel-Haenszel test method to calculate risk ratio (RR) or mean difference (MD) with 95% confidence intervals (CIs). Primary outcome was efficacy of prophylaxis. Secondary outcome was endoscopic severity of ulceration. The influence of study characteristics on the outcomes was examined by subgroup analyses. In preventing gastric ulcer occurrence, omeprazole prophylaxis was superior to sham in training horses (7 trials, 566 horses, RR 0.28, 95% CI 0.18 to 0.43; 23.4% in omeprazole prophylaxis versus 77.2% in sham; high quality evidence). Prevalence of ulceration was 75.3% and 87.2% in the sham arms of the 1 mg/kg and 2 mg/kg omeprazole groups, respectively. Severity scores were significantly lower for omeprazole versus sham (mean difference [MD] -1.05; 95% CI -1.35 to -0.69). Subgroup analyses comparing prophylactic omeprazole dosages resulted in a mean difference of -0.94 and -1.60 for the 1 mg/kg and 2 mg/kg groups, respectively. Studies showed heterogeneity with regard to prophylactic dose. Omeprazole prophylaxis in active training horses significantly reduces gastric ulceration compared with no prophylaxis

    Full Text Available The tripeptide thiol glutathione (γ-L-glutamyl-L-cysteinyl-glycine is the most important sulfur containing antioxidant in plants and essential for plant defense against abiotic and biotic stress conditions. It is involved in the detoxification of reactive oxygen species, redox signaling, the modulation of defense gene expression and important for the regulation of enzymatic activities. Even though changes in glutathione contents are well documented in plants and its roles in plant defense are well established, still too little is known about its compartment specific importance during abiotic and biotic stress conditions. Due to technical advances in the visualization of glutathione and the redox state of plants through microscopical methods some progress was made in the last few years in studying the importance of subcellular glutathione contents during stress conditions in plants. This review summarizes the data available on compartment specific importance of glutathione in the protection against abiotic and biotic stress conditions such as high light stress, exposure to cadmium, drought, and pathogen attack (Pseudomonas, Botrytis, Tobacco Mosaic Virus. The data will be discussed in connection with the subcellular accumulation of ROS during these conditions and glutathione synthesis which are both highly compartment specific (e.g. glutathione synthesis takes place in chloroplasts and the cytosol. Thus this review will reveal the compartment specific importance of glutathione during abiotic and biotic stress conditions.

    The paper describes the maxillo-facial and dental anomalies observed in some chromosome and non-chromosome poly-malformative syndromes ("Cri du chat" syndrome; Wilms' tumour; Sotos' syndrome; Goldenhar's syndrome). The Authors emphasise the possibility of diagnosing these multiple deformity syndromes from maxillo-facial alterations in early infancy; anomalous tooth position and structure cal also be successfully treated immediately after the first appearance of teeth. This is a particularly promising field of pediatrics and preventive pediatric medicine.
