Radiographics | Year: 2010
Magnetic resonance (MR) enterography is a clinically useful technique for the evaluation of both intraluminal and extraluminal small bowel disease, particularly in younger patients with Crohn disease. MR enterography offers the advantages of multiplanar capability and lack of ionizing radiation. It allows evaluation of bowel wall contrast enhancement, wall thickening, and edema, findings useful for the assessment of Crohn disease activity. MR enterography can also depict other pathologic findings such as lymphadenopathy, fistula and sinus formation, abscesses, and abnormal fold patterns. Even subtle disease manifestations may be detected when adequate distention of the small bowel is achieved, although endoscopic and double-contrast barium small bowel techniques remain superior in the depiction of changes in early Crohn disease (eg, aphthoid ulceration). Further research will be needed to determine whether MR imaging enhancement patterns may reliably help discriminate between active and inactive disease. © RSNA, 2010.

Renal function in patients with advanced cirrhosis is an important prognostic factor for survival both prior to and following liver transplantation. The importance of renal function is reflected by the introduction of the model for end stage liver disease (MELD) score, which includes serum creatinine. The MELD score has been shown to predict the short term risk of death for transplant wait listed patients and is currently used by many countries to allocate liver transplants on the basis of severity of underlying illness. Changes in serum creatinine are also used to stage acute kidney injury. However prior to liver transplantation the serum creatinine typically over estimates underlying renal function, particularly when a colorimetric Jaffe based assay is used, and paradoxically then under estimates renal function post liver transplantation, particularly when immunophyllins are started early as part of transplant immunosuppression. As acute kidney injury is defined by changes in serum creatinine, this potentially leads to over estimation of the incidence and severity of acute kidney injury in the immediate post-operative period. © 2014 Baishideng Publishing Group Inc.

Knee | Year: 2010
Total knee replacement is a well-established treatment for osteoarthritis with increasing numbers performed each year. Recurrent haemarthrosis is a relatively rare complication following TKR being reported in up to 1.6% of patients. While some causes are related to direct trauma to blood vessels, others are more obscure and may be difficult to diagnose. The purpose of this review is to give an overview of this unusual complication and summarise the current methods of management. © 2009 Elsevier B.V. All rights reserved.

PURPOSE: We performed a systematic review of the literature to determine the early and midterm outcomes of arthroscopic stabilization for posterior shoulder instability.METHODS: We searched PubMed, Embase, and the Cochrane Database of Systematic Reviews for related articles published in the English language. The 2 authors selected studies for inclusion or exclusion. The inclusion criteria included a minimum of 1 year of follow-up, with at least 20 patients in the study population.RESULTS: We included 6 studies, with a total of 387 patients (396 shoulders). All studies were retrospective, Level IV studies, except for 1 prospective study (Level II). In 81.06% of cases, patients reported a significant traumatic episode. The mean follow-up period was 44.4 months, and the mean recurrence rate was 5.37%. Most of the patients were able to return to sport (mean, 92.5%).CONCLUSIONS: The early and midterm results of arthroscopic stabilization of the shoulder for posterior instability are promising. Most of the patients were satisfied with the results of surgery and were able to return to sport. Larger studies and more prospective randomized trials are needed to confirm these findings.LEVEL OF EVIDENCE: Level IV, systematic review of 1 Level II study and 5 Level IV studies.

The past few decades have seen major advances in multidisciplinary obstetric care and management of gynecological conditions in women with bleeding disorders. Awareness of the impact of bleeding disorders has improved among the obstetric and gynecological community. Undiagnosed bleeding disorders can be the underlying cause for a significant proportion of women with heavy menstrual bleeding. They may also be the cause or a contributory factor for other gynecological problems, such as dysmenorrhea, intermenstrual bleeding, and endometriosis. Hemostatic assessment should be considered in women referred for menstrual abnormalities if they have a positive bleeding history as quantified by bleeding assessment tools. The reproductive choices and options for prenatal diagnosis are also expanding for families with hemophilia with a drive toward achieving a non-invasive approach. Current non-invasive prenatal diagnostic techniques are limited to identification of fetal gender. Research is ongoing to overcome the specific diagnostic challenges of identifying hemophilia mutations, utilizing free fetal DNA circulating in maternal plasma. The management of obstetric hemorrhage has recently evolved to include a greater focus on the identification of and early treatment for coagulation disorders. Deficiencies in certain hemostatic variables are associated with progression to more severe bleeding; therefore, specific interventions have been proposed to target this. Evidence is still lacking to support such strategy, and future research is required to assess the efficacy and the safety of these hemostatic interventions in women with persistent PPH. © 2013 International Society on Thrombosis and Haemostasis.

BMJ case reports | Year: 2012
An 84-year-old lady with a history of chronic recurrent rectal prolapse, presented to accident and emergency with a significant portion of small bowel and mesentery protruding out of her anus. The small bowel was not contained within peritoneum, nor was this a pararectal herniation. On examination of the rectum, a longitudinal tear was found in the anterior rectal wall, through which the small bowel had prolapsed. Hours after reducing the small bowel back into the anus, it prolapsed a second time. Due to multiple co-morbidities, this patient was not fit for surgery. The defect was temporarily repaired on the ward and the patient treated with aggressive antibiotic therapy. The patient continued to deteriorate, became septic, acidotic, hypotensive and died a day later.

Haemophilia | Year: 2012
Desmopressin (DDAVP) is commonly used for treatment and prevention of bleeding complications in patients with bleeding disorders including haemophilia A, von Willebrand's disease (VWD) and other less common disorders. This article reviews the current evidence for the use of DDAVP in pregnancy to clarify its efficacy and safety with regard to maternal and foetal outcome. A search of the literature found 30 studies that reported DDAVP use in pregnancy for prophylaxis or treatment of bleeding complications with 216 pregnancies reported in total. The most common indication was prophylaxis for prevention of bleeding during pregnancy and postpartum haemorrhage. DDAVP was used successfully in the first and early second trimester for bleeding prophylaxis in 50 pregnancies. No postpartum bleeding complications were reported in 167 out of 172 pregnancies when DDAVP was used for peripartum haemostatic cover. Twenty-nine studies reported no significant adverse events as a result of treatment with DDAVP. One case of water intoxication seizure and one case of premature labour following the use of DDAVP was reported in a single study. Other maternal side effects included facial flushing and headache and were reported by one study. These side effects were generally well tolerated by patients. There were no other significant adverse events reported in any of the studies as a result of DDAVP use. Foetal outcome was recorded in ten studies with no adverse foetal outcomes. In conclusion, this review shows that DDAVP in selected cases is effective in reducing bleeding complications associated with pregnancy and childbirth with a good safety record. Further research is needed to confirm these findings as they are based on the currently available evidence from small studies and case series only. © 2011 Blackwell Publishing Ltd.

Haemophilia | Year: 2011
Pregnancy, labour and delivery present intrinsic haemostatic challenges to women with and carriers of bleeding disorders and their offspring. Deficiency of fibrinogen and factor XIII are associated with miscarriage, placental abruption and foetal loss. The risk of antenatal complications including antepartum haemorrhage is unknown in women with other bleeding disorders. There is a significant risk of postpartum haemorrhage (primary and secondary) in women with all types of bleeding disorders. This can be serious and life threatening in those with severe defects such as Bernard Soulier syndrome and Glanzmann's thrombasthenia. Three to four percent of infants with haemophilia experience cranial bleeding that occurs during labour and delivery. The safest method of delivery for affected babies remains controversial. However, the rate of planned Caesarean section is increasing among known carriers of haemophilia. If vaginal delivery is planned, prolonged labour and difficult delivery especially vacuum extraction are associated with the highest risk of cranial bleeding and should be avoided. The optimal management of pregnancy in women with inherited bleeding disorders requires a multidisciplinary approach and advanced individualized management plan taking into consideration obstetric and bleeding risk factors. Women with mild or moderate bleeding disorders can be managed at their local maternity unit in close collaboration with a tertiary centre. However, those with severe or rare disorders or carrying an affected infant should be managed in a tertiary centre with an onsite Haemophilia centre. © 2011 Blackwell Publishing Ltd.

Haemophilia | Year: 2012
Total knee arthroplasty, or replacement (TKR), is now the most commonly performed surgical procedure performed in adults with haemophilia. It is indicated when end-stage haemophilic arthropathy results in intractable pain and reduced function. In patients with haemophilia, however, there has always been a concern about the high risk of infection, which carries with it potentially catastrophic consequences. The aims of this study were to review the case series of TKR for haemophilic arthropathy published in the medical literature, comparing the published infection rates and the differing clotting factor replacement regimes employed. Nineteen retrospective case series were identified; representing 556 TKR's in 455 patients with an overall infection rate of 7.9%. Case series which maintained a high level of clotting factor replacement throughout the first two postoperative weeks, however, had an infection rate of 2.15%, significantly lower than that of case series using the clotting factor replacement regime currently recommended in the World Federation of Hemophilia guidelines (9.22%P=0.00545). We believe this study supports the use of a high level clotting factor replacement regime, replacing clotting factors to maintain them at a higher level for a longer period of time than currently recommended in international guidelines. © 2011 Blackwell Publishing Ltd.
