Huge adrenal haemangioma

Adrenal tumours are either functioning or non-functioning. Non-functioning adrenal tumours are generally asymptomatic and usually of enormous proportions at the time of presentation. A case is presented here of a patient with a huge right adrenal haemangioma which was successfully treated surgically. This unusual tumour was 25 cm in diameter, was well encapsulated and weighed 4 kg. The literature pertaining to this interesting case is reviewed.     

Detection of Undiagnosed Coeliac Disease with Atypical Features Using Antireticulin and Antigliadin Antibodies

Eighteen patients with a variety of non-gastrointestinal symptomswere incidentally found to have circulating antireticulin antibodyand on subsequent testing were also positive for antigliadinantibody. They prospectively underwent jejunal biopsy to determinewhether or not they had coeliac disease. Their age range was21–79 years (mean 42 years). Enteropathy was present in13 (72 per cent) and was always associated with circulatingIgA antigliadin antibody. Enteropathy was not present in thefive cases who had only IgG antibody. Clinical improvement occurredin eight of 11 patients who complied with a gluten-free dietand was paralleled by an improvement in the mucosal histologyin seven of eight who were re-biopsied. The most remarkablecases were two patients who presented with severe debility andno apparent haematological or biochemical abnormalities, andwho subsequently made a dramatic recovery on a gluten-free diet.It is concluded that antireticulin antibody detected by routineautoantibody screening and confirmed to have IgA antigliadinantibody specificity is a useful indicator of an otherwise undiagnosedenteropathy. This serves to emphasize that the condition cansometimes be associated with atypical features and significantmorbidity.     

Non-invasive coronary angiography with multi-detector computed tomography: comparison to conventional X-ray angiography

Selective coronary angiography introduced clinical coronary imaging in the late 1950s. The angiographic identification of high-grade coronary lesions in patients with acute and chronic symptomatic coronary artery disease (CAD) led to the development of surgical and percutaneous coronary revascularization. However, the fact that CAD remains the major cause of death in North America and Europe demonstrates the need for novel, complementary diagnostic strategies. These are driven by the need to characterize both increasingly advanced disease stages but also early, asymptomatic disease development. Complex revascularization techniques for patients with advanced disease stages will initiate a growing demand for 3-dimensional coronary imaging and integration of imaging modalities with new mechanical therapeutic devices. An emerging focus is atherosclerosis imaging with the goal to identify subclinical disease stages as the basis for pharmacological intervention aimed at disease stabilization or reversal. Non-invasive coronary imaging with coronary multidetector computed tomographic angiography (MDCTA) allows both assessment of luminal stenosis and subclinical disease of the arterial wall. Its complementary role in the assessment of early and advanced stages of CAD is increasingly recognized.     

Verletzungsmuster und -ursachen in modernen Kriegen

Epidemiological analyses of injury patterns and mechanisms help to identify the expertise military surgeons need in a combat setting and accordingly help to adjust infrastructure and training requirements. Therefore, a MEDLINE search (1949–2009), World Wide Web search (keywords “combat, casualties, war, military, wounded and neurosurgery”) and an analysis of deaths among allied war casualties in Afghanistan and Iraq were performed. Up to 10th December 2009 there had been 4,688 allied military deaths in Iraq and 1,538 in Afghanistan. Of these 22% died in non-hostile action, 33% in direct combat situations and the majority of 45% in indirect combat actions. The leading causes of injury were explosive devices (70%) and gunshot wounds. Chest or abdominal injuries (40%) and traumatic brain injuries (35%) were the main causes of death for soldiers killed in action. The case fatality rate in Iraq is approximately half that of the Vietnam War, whereas the killed-in-action rate in Afghanistan (18.7%) is similar to the Vietnam War (20%); however, the amputation rate is twice as high in modern conflicts. Approximately 8–15% of the fatal injuries seem to be potentially survivable. Military surgeons must have an excellent expertise in a wide variety of surgical specialties. Life saving emergency care, especially in the fields of thoracic, visceral and vascular surgery as well as practical skills in the fields of neurosurgery and oral and maxillofacial surgery are required. Additionally, it is of vital importance to ensure the availability of sufficient tactical and strategic medical evacuation capabilities for the wounded.     

Persistence of CCR5 usage among primary human immunodeficiency virus isolates of individuals receiving intermittent interleukin‐2

Objective

To investigate the impact of intermittent interleukin‐2 (IL‐2) plus combination antiretroviral therapy (cART) on HIV‐1 entry co‐receptor use.

Methods

Primary HIV‐1 isolates were obtained from 54 HIV‐1‐positive individuals at baseline and after 12 months using co‐cultivation of peripheral blood mononuclear cells (PBMC) with activated PBMC of HIV‐negative healthy donors. HIV‐1 co‐receptor use was determined on U87‐CD4 cells.

Results

Fourteen out of the 21 (67%) IL‐2‐treated individuals harbouring a primary CCR5‐dependent (R5) HIV‐1 isolate at baseline confirmed an R5 virus isolation after 12 months in contrast to 3 out of 7 (43%) of those receiving cART only. After 12 months, only 1 R5X4 HIV‐1 isolate was obtained from 21 cART+IL‐2‐treated individuals infected with an R5 virus at entry (5%) vs. 2/7 (29%) patients receiving cART alone, as confirmed by a 5‐year follow‐up on some individuals.

Conclusions

Intermittent IL‐2 administration plus cART may prevent evolution towards CXCR4 usage in individuals infected with R5 HIV‐1.
