Venous thromboembolism after oral and maxillofacial oncologic surgery : report and analysis of 14 cases in Chinese population

Venous thromboembolism (VTE) including deep vein thrombosis (DVT) and pulmonary embolism (PE) is a leading cause of death in cancer patients. The aim of this study was to explore the potential risk factor of VTE in oral and maxillofacial oncological surgery. The data of patients who received operation in our institution were gathered in this retrospective study. A diagnosis of VTE was screened and confirmed by computer tomography angiography (CTA) of pulmonary artery or ultrasonography examination of lower extremity. Medical history and all perioperative details were analyzed. 14 patients were diagnosed as VTE, including 6 cases of PE, 7 cases of DVT, 1case of DVT and PE. The mean age of these patients was 62.07 years. Reconstruction was performed in 12 patients of these cases, most of which were diagnosed as malignance. Mean length of surgery was 8.74 hours, and lower extremity deep venous cannula (DVC) was performed in all these patients. We analyzed several characters of oral and maxillofacial surgery and suggested pay attention to lower extremity DVC which had a high correlation with DVT according to our data

Metoclopramide for post-pyloric placement of naso-enteral feeding tubes

Background Enteral nutrition by feeding tube is a common and efficient method of providing nutritional support to prevent malnutrition in hospitalised patients who have adequate gastrointestinal function but who are unable to eat. Gastric feeding may be associated with higher rates of food aspiration and pneumonia than post-pyloric naso-enteral tubes. Thus, enteral feeding tubes are placed directly into the small intestine rather than the stomach, and the use of metoclopramide, a prokinetic agent, has been recommended to achieve post-pyloric placement, but its efficacy is controversial. Moreover, metoclopramide may include adverse reactions, which with high doses or prolonged use may be serious and irreversible. Objectives To determine the effect of intravenous metoclopramide on post-pyloric placement of the naso-enteral tube in adults. Search methods Trials were identified by searching the Cochrane Central Register of Controlled Trials (CENTRAL; 2014, Issue 10) which includes the CUGPD group's specialised register of trials, MEDLINE (1996 to 21 October 2014), EMBASE (1988 to 21 October 2014), LILACS (2005 to 21 October 2014) We did not confine our search to English language publications. Searches in all databases were updated originally in January 2005, then in November 2008 and again in October 2014. No new studies were found in 2008 or in 2014. Selection criteria We selected randomised controlled trials of adults needing enteral nutrition, who received intravenous or intramuscular metoclopramide to aid placement of transpyloric naso-enteral feeding tubes, compared to placebo or no intervention. Data collection and analysis We used standard methodological procedures expected by The Cochrane Collaboration. All analyses were performed according to the intention-to-treat method. We present risk ratios (RR) with 95% confidence intervals (CI). Main results Four studies, with a total of 204 participants were included and analysed. The trials compared metoclopramide with placebo (two trials) or with no intervention (two trials). Metoclopramide was investigated at doses of 10 mg (two trials) and 20 mg (two trials). There was no statistically significant difference between metoclopramide versus placebo or no intervention administered to promote tube placement (RR 0.82, 95% CI 0.61 to 1.10). Metoclopramide at doses of 10 mg (RR 0.82, 95% CI 0.60 to 1.11) and 20 mg (RR 0.62, 95% CI 0.15 to 2.62) were equally ineffective in facilitating post-pyloric intubation when compared with placebo or no intervention. Authors' conclusions In this review, we found only four studies that fitted our inclusion criteria. These were small, underpowered studies, in which metoclopramide was given at doses of 10 mg and 20 mg. Our analysis showed that metoclopramide did not assist post-pyloric placement of naso-enteral feeding tubes. Ideally randomised clinical trials should be performed that have a significant sample size, administering metoclopramide against control, however, given the lack of efficacy revealed by this review it is unlikely that further studies will be performe

Orthodontic treatment as triggering factor of medication related osteonecrosis of the jaw in a breast cancer patient. Report of a rare case

Orthodontic treatment in adult patient is widely accepted nowadays. Therefore, orthodontists are needed to interact with more complex medical histories that may interfere with the orthodontic treatment. Antiresorptive medication is a widely used treatmen

A multicentre, randomised controlled trial comparing the clinical effectiveness and cost-effectiveness of early nutritional support via the parenteral versus the enteral route in critically ill patients (CALORIES).

BACKGROUND: Malnutrition is a common problem in critically ill patients in UK NHS critical care units. Early nutritional support is therefore recommended to address deficiencies in nutritional state and related disorders in metabolism. However, evidence is conflicting regarding the optimum route (parenteral or enteral) of delivery. OBJECTIVES: To estimate the effect of early nutritional support via the parenteral route compared with the enteral route on mortality at 30 days and on incremental cost-effectiveness at 1 year. Secondary objectives were to compare the route of early nutritional support on duration of organ support; infectious and non-infectious complications; critical care unit and acute hospital length of stay; all-cause mortality at critical care unit and acute hospital discharge, at 90 days and 1 year; survival to 90 days and 1 year; nutritional and health-related quality of life, resource use and costs at 90 days and 1 year; and estimated lifetime incremental cost-effectiveness. DESIGN: A pragmatic, open, multicentre, parallel-group randomised controlled trial with an integrated economic evaluation. SETTING: Adult general critical care units in 33 NHS hospitals in England. PARTICIPANTS: 2400 eligible patients. INTERVENTIONS: Five days of early nutritional support delivered via the parenteral (n = 1200) and enteral (n = 1200) route. MAIN OUTCOME MEASURES: All-cause mortality at 30 days after randomisation and incremental net benefit (INB) (at £20,000 per quality-adjusted life-year) at 1 year. RESULTS: By 30 days, 393 of 1188 (33.1%) patients assigned to receive early nutritional support via the parenteral route and 409 of 1195 (34.2%) assigned to the enteral route had died [p = 0.57; absolute risk reduction 1.15%, 95% confidence interval (CI) -2.65 to 4.94; relative risk 0.97 (0.86 to 1.08)]. At 1 year, INB for the parenteral route compared with the enteral route was negative at -£1320 (95% CI -£3709 to £1069). The probability that early nutritional support via the parenteral route is more cost-effective - given the data - is < 20%. The proportion of patients in the parenteral group who experienced episodes of hypoglycaemia (p = 0.006) and of vomiting (p < 0.001) was significantly lower than in the enteral group. There were no significant differences in the 15 other secondary outcomes and no significant interactions with pre-specified subgroups. LIMITATIONS: Blinding of nutritional support was deemed to be impractical and, although the primary outcome was objective, some secondary outcomes, although defined and objectively assessed, may have been more vulnerable to observer bias. CONCLUSIONS: There was no significant difference in all-cause mortality at 30 days for early nutritional support via the parenteral route compared with the enteral route among adults admitted to critical care units in England. On average, costs were higher for the parenteral route, which, combined with similar survival and quality of life, resulted in negative INBs at 1 year. FUTURE WORK: Nutritional support is a complex combination of timing, dose, duration, delivery and type, all of which may affect outcomes and costs. Conflicting evidence remains regarding optimum provision to critically ill patients. There is a need to utilise rigorous consensus methods to establish future priorities for basic and clinical research in this area. TRIAL REGISTRATION: Current Controlled Trials ISRCTN17386141.

A rare case of intussusception leading to the diagnosis of acquired immune deficiency syndrome: a case report

<p>Abstract</p> <p>Introduction</p> <p>Although a common cause of intestinal obstruction in children, intussusception is a rare event in the adult population living in temperate regions. It has long been known that various acquired immune deficiency syndrome related conditions of the bowel such as lymphoma, lymphoid hyperplasia, cytomegalovirus colitis and Kaposi's sarcoma can lead to intussusception. The diagnosis is particularly difficult in this population of patients due to the non-specific nature of the symptoms as well as the depressed immune response obscuring inflammation or ischemia. Though the reported acquired immune deficiency syndrome associated cases of intussusception refer to patients with known human immunodeficiency virus infection, in our case we present an intestinal intussusception as the first manifestation of human immunodeficiency virus infection.</p> <p>Case presentation</p> <p>A 58-year-old white heterosexual Greek man with a clean medical record and no history of abdominal operation presented to the emergency department with symptoms and signs of bowel obstruction. Plain abdominal radiographs were highly suspicious for intussusception which was eventually confirmed on a computed tomography scan. Due to the patients clean medical record as well as the radiologic diagnosis of intussusception, we promptly undertook further serologic tests for human immunodeficiency virus and eventually established the diagnosis of acquired immune deficiency syndrome. The patient was operated 3 days later and this confirmed the diagnosis of small-bowel invagination due to a 4 cm polypoid growing intraluminal tumor, the pathologic examination of which revealed a diffuse high-grade B cell lymphoblastic lymphoma.</p> <p>Conclusion</p> <p>Human immunodeficiency virus infection may have a silent course and gastrointestinal manifestations of the disease leading to intussusception might be the first clinical sign. Patients with intestinal intussusception, and the presence of risk factors for human immunodeficiency virus infection should be eligible for serologic tests for human immunodeficiency virus infection.</p

Preoperative muscle weakness as defined by handgrip strength and postoperative outcomes: a systematic review

<p>Abstract</p> <p>Background</p> <p>Reduced muscle strength- commonly characterized by decreased handgrip strength compared to population norms- is associated with numerous untoward outcomes. Preoperative handgrip strength is a potentially attractive real-time, non-invasive, cheap and easy-to-perform "bedside" assessment tool. Using systematic review procedure, we investigated whether preoperative handgrip strength was associated with postoperative outcomes in adults undergoing surgery.</p> <p>Methods</p> <p>PRISMA and MOOSE consensus guidelines for reporting systematic reviews were followed. MEDLINE, EMBASE, and the Cochrane Central Register of Controlled Clinical Trials (1980-2010) were systematically searched by two independent reviewers. The selection criteria were limited to include studies of preoperative handgrip strength in human adults undergoing non-emergency, cardiac and non-cardiac surgery. Study procedural quality was analysed using the Newcastle-Ottawa Quality Assessment score. The outcomes assessed were postoperative morbidity, mortality and hospital stay.</p> <p>Results</p> <p>Nineteen clinical studies (17 prospective; 4 in urgent surgery) comprising 2194 patients were identified between1980-2010. Impaired handgrip strength and postoperative morbidity were defined inconsistently between studies. Only 2 studies explicitly ensured investigators collecting postoperative outcomes data were blinded to preoperative handgrip strength test results. The heterogeneity of study design used and the diversity of surgical procedures precluded formal meta-analysis. Despite the moderate quality of these observational studies, lower handgrip strength was associated with increased morbidity (n = 10 studies), mortality (n = 2/5 studies) and length of hospital stay (n = 3/7 studies).</p> <p>Conclusions</p> <p>Impaired preoperative handgrip strength may be associated with poorer postoperative outcomes, but further work exploring its predictive power is warranted using prospectively acquired, objectively defined measures of postoperative morbidity.</p
