3 cases of copper IUDs recovered during laparotomy from the sigmoid colon are presented. One woman was a 24-year old mother of 5 who had had 2 cesarean sections since the disappearance of her Cu-7 IUD in 1980. She had right upper quadrant abdominal pain for 1 year with gall bladder stones. The IUD was found lying 80% in the gut lumen. After colotomy she recovered. The 2nd woman was 31 years old, pregnant for the 4th time after failure of her IUD. She was experiencing a constant left iliac fossa ache. The IUD was shown to be extrauterine by ultrasound, could not be seen at laparoscopy, and was removed by colotomy. The 3rd woman was a 37-year old mother of 5, 19 weeks' pregnant, having a septic miscarriage on admission. She had labor induced, but the IUD was not expelled. Her pain worsened, and fever and tachycardia persisted. Emergency laparotomy revealed a perforated posterior uterine wall with the Cu-7 eroding the serosa of the sigmoid colon. It was removed but the defect was not repaired. She required a subtotal hysterectomy, and a second laparotomy with a temporary colostomy, and her recovery was complicated by pulmonary embolism and cardiac failure. These cases draw attention to the importance of proper management of patients with no visible IUD thread. Ultrasound, and if necessary x-rays and laparoscopy should precede laparotomy. Expulsion of an IUD is rarely unnoticed, nor should pregnancy with an IUD be assumed to be due to an expelled device.

Although the use of silicone catheters for long-term central venous access is widespread, little is known about the incidence of pulmonary thromboembolic complications. We studied clinical events, lung perfusion scans, and echocardiographic screens in 34 children and adolescents with gut failure who had received cyclical parenteral nutrition for 2 months to 9 years. Major thrombosis and/or embolism was identified in 12 patients and 4 died as a consequence. Actuarial survival free from thrombosis was 53% at 5 years (95% Cl, 30-77%). Survival free from fatal pulmonary thromboembolic events was 74% at 5 years (48-99%). 3 patients required surgery to remove right atrial thrombus or pulmonary emboli. Major right atrial thrombosis and pulmonary embolism are common and potentially fatal complications of parenteral nutrition by long-term venous access in childhood. Anticoagulation is recommended.

A patient was admitted to the intensive care unit because of respiratory failure, and warfarin therapy was started at 2 mg/day for the treatment of pulmonary embolism, together with other medications. Despite the low dosage of warfarin, international normalized ratio (INR) was markedly elevated from 1.15 to 11.28 for only 4 days, and bleeding symptoms concurrently developed. Vitamin K2 was infused along with discontinuation of warfarin. One day later, the INR was found to have decreased, and bleeding was also improved. An objective causality assessment indicated a probable relationship between clotting abnormality and warfarin administration, although the degree of elevation of the INR was unusual in the light of the daily warfarin dose and duration of its exposure. Based on the clinical status of the patient, it was suspected that several conditions contributed to the abnormal hypersensitivity to warfarin. Contributory factors probably included pharmacokinetic interactions with co-administrated drugs, vitamin K deficiency caused by decreased dietary intake, reduced gut bacterial production, impaired intestinal absorption and hepatic synthetic capacity, and increased consumption of clotting factors. In view of our experience in the present case, it should be stressed that close monitoring of coagulation capacity is necessary in critically ill patients in order to avoid fatal haemorrhage after initiating warfarin therapy regardless of the dosage.

The ability of the somatosensory system to detect noxious and potentially tissue-damaging stimuli is an important protective mechanism, that involves multiple interacting peripheral and central mechanisms. The postoperative pain is related with surgical procedure irrevocable. The effective relief of pain is of paramount importance to anyone treating patients undergoing surgery. This should be achieved for humanitarian reasons, but there is now evidence that pain relief has significant physiological benefit. Not only does effective pain relief mean a smoother postoperative course with earlier discharge from hospital, but it may also reduce the onset of chronic pain syndromes. Pain causes an increase in the sympathetic response of the body with subsequent rises in heart rate, cardiac work and oxygen consumption. Prolonged pain can reduce physical activity and lead to venous stasis and an increased risk of deep vein thrombosis and consequent pulmonary embolism. In addition, there can be widespread effects on gut and urinary tract motility which may lead, in turn, to postoperative ileus, nausea, vomiting and urinary retention. These problems are unpleasant for the patient and may prolong hospital stay. Choice of technique will also be influenced by the degree of training and expertise of the staff. The choice of pain-relieving techniques may be influenced by the site of surgery.

Pulmonary hypertension (PH) is common in the critical care setting, and may be a target for specific therapy. Moderate degrees of pulmonary hypertension are most often the consequence of acute or chronic heart failure, hypoxemia, or acute pulmonary embolism, and may be relatively rapidly reversible. The consequences of more severe forms of PH, both acute and chronic, can include hypotension; low cardiac output; right heart failure with congestion of the liver, gut, and kidneys; and varying degrees of hypoxemia, each of which can lead to death or severe disability. We review the physiology, definitions, classification, pathogenesis, diagnostic tools, and algorithms for diagnosis and specific treatments for the various causes of PH as seen in the critical care setting.

Crohn's disease (CD) and ulcerative colitis (UC), the two major forms of inflammatory bowel disease (IBD), are chronic inflammatory conditions, characterized by a microvascular and also macrovascular involvement. Chronically inflamed intestinal microvessels of IBD patients have demonstrated significant alterations in their physiology and function compared with vessels from healthy and uninvolved IBD intestine. Recently, some studies have revealed that the poor mucosal healing, refractory inflammatory ulcerations and damage in the IBD intestine could depend on microvascular dysfunction, resulting in diminished vasodilatory capacity and tissue hypoperfusion in the IBD gut. Furthermore, several data show that the activation of intestinal endothelium plays a critical role in the pathogenesis and/or in perpetuating and amplifying the inflammatory process in IBD and, consequently, it is now emerging as a potential use of anticoagulant or coagulation-related drugs in treating IBD. IBD is also associated with an increased risk of macrovascular venous and arterial thrombosis. Thrombotic events occur prevalently as deep vein thrombosis and pulmonary embolism. They happen at an earlier age than in non-IBD patients. Prothrombotic risk factors in IBD patients could be distinguished as acquired, such as active inflammation, immobility, surgery, steroid therapy, and use of central venous catheters, and inherited. Furthermore, it has been found that IBD, per se, is an independent risk factor for thrombosis. The prevention of thromboembolic events in IBD patients includes the elimination of removable risk factors and, if thrombosis occurs, a pharmacological therapy similar to that used for thromboembolic events occurring in the general population.

A previously well 59-year-old lady with 70 kg weight loss and chronic diarrhoea over a 28-month period presented following collapse and subsequent diagnosis of pulmonary embolism. Previous investigations for this weight loss included normal gastroscopy and colonoscopy, CT and MRI abdomen, barium follow through and octreotide scan. She underwent echocardiogram which revealed myocardial speckling and asymmetrical left ventricular hypertrophy. Repeat oesophago-gastro-duodenoscopy and colonoscopy for rectal bleeding was performed. Colonoscopy revealed intramucosal haematomas and electron microscopy (EM) of the gastric biopsies confirmed amyloid deposition. Amyloidosis of the gastrointestinal (GI) tract and heart were confirmed on serum amyloid protein scan. GI amyloid is rare and symptoms include weight loss, diarrhoea, GI bleeding and gut dysmotility.1 GI amyloidosis should be considered as a diagnosis and sought when other common causes have been excluded. The greatest yield is by Congo red staining or EM of rectal specimens.
