A retrospective study of cesarean hysterectomies at the Department of Obstetrics and Gynecology in Novi Sad was conducted for the period 1968-1993. There were 129,127 deliveries, whereas cesarean section was performed in 10,485 (8.12%) cases. There were 55 cesarean hysterectomies (0.042%), while in 0.52% they were performed during cesarean section. Elective hysterectomy was performed in 7 (12.73%) cases because of neoplastic process and uterine myoma, while in 48 (87.27%) cases it was performed for heavy bleeding. Most often bleeding occurred due to complications of placenta previa, uteroplacental apoplexy, premature placental ablation, uterine rupture and atony. Total hysterectomy was performed in 30 (54.54%) cases and subtotal hysterectomy in 25 (45.45%) cases. Bilateral adnexectomy was performed in 3 (5.45%) cases. Urinary bladder injury occurred in 4 (7.27%) patients, wound infection in 11 (20.00%) patients, urinary infection in 3 (5.45%) and pelvic peritonitis in 1 (1.82%) patient. One maternal death (1.82%) occurred due to DIC (disseminated intravascular coagulation). Out of 57 delivered newborns 20 (35.10%) died in the perinatal period. There were 13 stillbirths (22.80%), whereas 7 newborns (12.30%) died in the early neonatal period due to prematurity and RDS (respiratory distress syndrome).

Pancreatico-jejunal anastomosis still represents the main source of postoperative complications after pancreatoduodenectomy. In this study our experience on the occlusion of the residual pancreatic stump instead of pancreatico-jejunal anastomosis is reviewed. Between March 1981 and December 1995 we performed 223 pancreatoduodenectomies using Neoprene injection into the Wirsung duct for pancreatic carcinoma of the head (123 cases), ampullary carcinoma (36 cases), distal bile duct cancer (23 cases), islet cells carcinoma (17 cases), chronic pancreatitis (11 cases), duodenal carcinoma (5 cases), miscellaneous diseases (8 cases). Neoprene is a fluid, synthetic glue which polymerized and hardens when in contact with the pancreatic juice, inducing a fibrosis tissue which spares the endocrine component. We observed a 4.9% operative mortality (11 patients): 5 abdominal sepsis, 1 DIC, 1 aortoiliac thrombosis, 1 pulmonary embolism, 1 stroke, 1 hepatic failure, 1 cardiac failure. Overall morbidity was 44.8% (100 patients): in 25 cases (11.2%) a major complication requiring reintervention occurred. In 38 patients (17%) pancreatic fistula was detected: median duration was 43 days, with a mean output of 5.3 ml/day; in all cases a spontaneous solution of the fistula was observed. In conclusion, intraductal injection of Neoprene after pancreatoduodenectomy is a safe procedure, it represents an useful alternative to pancreatico-jejunal anastomosis.

In a 38-year-old man, severe heat stroke caused disseminated intravascular coagulation (DIC) associated with significantly elevated plasma plasminogen activator inhibitor 1 levels. Investigation of the effects of hyperthermia on coagulation and fibrinolysis showed, in apparent conflict with previous reports, a time lag between the initial hypercoagulable and hyperfibrinolytic response (within 24 hr) and hypofibrinolysis shown by a disproportionate increase of PAI-1 (after 24 h), which possibly occurs in correspondence with the recovery of vascular endothelial integrity. The patient was discharged without sequelae although computed tomography (CT) scans indicated the likelihood of venous infarction or posterior inferior cerebellar artery area infarction secondary to DIC.

We report the case of a 70-year-old man who had an acute dissection of a previously undiagnosed thoracic aortic aneurysm. The diagnosis was challenging because of the neurologic and hematologic complications that overwhelmed the clinical presentation. Three simultaneous complications of thoracic aortic aneurysm with dissection (ischemic stroke, consumption coagulopathy, and superior mesenteric infarction with gastrointestinal hemorrhage) made the case unique and the diagnosis difficult.

Eclampsia is defined as the occurrence of seizures in pregnancy or within 10 days of delivery, accompanied by at least two of the following features documented within 24 hours of the seizure: hypertension, proteinuria, thrombocytopenia or raised aspartate amino transferase. Eclampsia complicates approximately one in 2,000 pregnancies in the United Kingdom and it remains one of the main causes of maternal death. Up to 38% of cases of eclampsia can occur without premonitory signs or symptoms of pre-eclampsia-that is, hypertension, proteinuria, and oedema. Only 38% of eclamptic seizures occur antepartum; 18% occur during labour and a further 44% occur postpartum. Rare cases of eclampsia have occurred over a week after delivery. Outcome is poor for mother and child. Almost one in 50 women suffering eclamptic seizures die, 23% will require ventilation and 35% will have at least one major complication including pulmonary oedema, renal failure, disseminated intravascular coagulation, HELLP syndrome, acute respiratory distress syndrome, stroke, or cardiac arrest. Stillbirth or neonatal death occurs in approximately one in 14 cases of eclampsia. Up to one third of eclamptic seizures occur out of hospital. For this reason, initial management may involve accident and emergency departments. Early involvement of senior obstetric staff is crucial. Optimal emergency management of seizures, hypertension, fluid balance and subsequent safe transfer is essential to minimise morbidity and mortality.

Unusual causes of stroke account for a minority of all strokes, but they have specific diagnostic and therapeutic implications which must be considered early in the clinical course. This article focuses on arteriopathies such as arterial dissection, vasospasm-induced stroke, and vasculitis; hematological disorders such as hypercoagulable states, disseminated intravascular coagulation, and sickle cell disease; migraine-induced stroke, and cerebral venous thrombosis.

Measurement of D-dimer (fibrin degradation product) is important for determining not only the activation of fibrinolysis but also the severity of a hypercoagulable state. However, fibrin degradation products are in variable, and the reactivity to cross-linked fibrin degradation products produced during fibrin degradation differs depending on the kind of antibody used against D-dimer. In patients with disseminated intravascular coagulation or earthquake-induced mental and physical stress and in patients after percutaneous transluminal coronary angioplasty, all of which are associated with acute fibrin formation and degradation, some discrepancies between two methods of D-dimer detection, automated latex agglutination assay (LPIA) and enzyme-linked immunosorbent assay (Stago), were found. No discrepancies in persistent fibrin formation and degradation were found among the healthy elderly, patients with lacunar stroke, and patients with coronary artery disease, almost all of whom had levels under 5.0 microg/mL, as determined by both methods. Evidence of persistently increased intravascular coagulation and fibrin turnover in patients with atherosclerotic disease was found. The cleavage of cross-linked fibrin by plasmin results in a production of fibrin degradation products, mostly contained D-dimer domains. Although the clinical utility of D-dimer can be achieved by their detection with specific antibodies, measurement of D-dimer as high-molecular-weight fragments may be useful to determine whether patients will undergo further fibrin degradation. When intermediate products of the degradation process need to be assessed, D-dimer level measurement by LPIA may serve as a suitable marker for ongoing fibrinolysis.

Heat stroke, which is also known as "sun stroke," is a medical emergency, and fatalities can occur unless it is diagnosed early and treated efficiently. Heat stroke may manifest quite suddenly, giving little time to differentiate it from extreme physical exhaustion in collapsed subjects. It is also known to lead to serious disseminated intravascular coagulation. Sudden death in a young female is presented who collapsed after trekking in a hilly, jungle area in Malaysia on a warm, humid day. She had joined a weight reduction programme a few weeks earlier. She was found collapsed and in a semiconscious state in the jungle by her groupmates and was taken to hospital. On admission she was unconscious, hyperpyrexic, with rapid, thready pulse and a low blood pressure. Biochemical studies revealed metabolic acidosis, elevated liver and cardiac enzymes and impairment of renal function. Her coagulation profile was found to be impaired and she started bleeding through the mouth and nostrils. She also developed watery diarrhoea and initially a septicaemic condition, including acute enteritis was suspected. Despite active treatment, her condition deteriorated and she died eight hours after admission. Autopsy confirmed a generalised bleeding tendency, with pulmonary, oesophageal and gastrointestinal mucosal haemorrhages. Flame-shaped subendocardial shock haemorrhages were seen in the interventricular septum on the left side of the heart. The findings support a diagnosis of heat stroke. Various aspects related to heat stroke, the autopsy diagnosis and its prevention are discussed.

Use of hyperthermia in the treatment of cancer and viral infection has received renewed interest. However, the in vivo relationship between hyperthermia and direct versus indirect effects upon hemostasis are incompletely defined, although we do know that disseminated intravascular coagulation (DIC) is a common sequel to heat stroke. The purpose of the present study was to more precisely define the relationship between hyperthermia and derangements of hemostasis, thereby providing a guideline for the development of safe hyperthermia treatment regimens. The present investigation examined the in vivo effects of high-grade whole-body hyperthermia (WBH) (42.5 degrees C, 90 min) on hemostasis in a canine model. Induction of hyperthermia via extracorporeal circulation of heated blood (ECC-WBH) caused thrombocytopenia, increased plasma fibrin degradation products (FDPs), prolonged clotting times, increased serum liver enzymes, and evidence of spontaneous bleeding. However, when WBH was induced by peritoneal lavage (PL-WBH), transient thrombocytopenia was the only significant alteration. Temporal correlation between hemostatic alterations and elevations in serum alanine aminotransferase (ALT) levels in the ECC-WBH treatment group suggested that liver injury is responsible, at least in part, for the coagulopathy associated with high-grade hyperthermia and that in the absence of liver injury, identical degrees of hyperthermia cause only incidental decreases in platelet numbers.

The development of deep venous thrombosis and the ensuing secondary complications of pulmonary embolism, disseminated intravascular coagulation, and stroke may be produced in high altitude climbers as a result of acclimatization to altitude. To prevent these serious disorders, investigation for predisposing risk factors and consideration of anticoagulative therapy should be considered.
