The ingestion of one or two alcoholic drinks can affect heart rate, blood pressure, cardiac output, myocardial contractility, and regional blood flow. These actions generally are not clinically important. In the presence of cardiovascular disease, however, even such small quantities of alcohol might result in transient unfavorable hemodynamic changes. Moreover, alcohol abuse can produce cardiac arrhythmias, hypertension, cardiomyopathy, stroke, and even sudden death. In contrast, moderate alcohol use produces changes that have an overall favorable effect on atherosclerotic-related vascular diseases. Because cardiovascular disease due to atherosclerosis is the leading cause of death in Western society, this desirable effect of alcohol use outweighs its detrimental actions, resulting in favorable findings in population studies. Nevertheless, the body of evidence argues against encouraging alcohol use for its cardiovascular effects.

The number of pregnancies following liver transplantation is increasing due to better patient and graft survival and quality of life. Out of 156 women of a reproductive age, there were 19 pregnancies in 16 women, 12 on CsA and seven on tacrolimus, which occurred between 7/92 and 1/97. The median age of the women was 27.9 yr, median time after transplantation 33 months. There were four spontaneous and two induced abortions in the first trimenon. Ten women delivered ten healthy babies; three newborns had problems (alcoholic embryopathy due to recurrent alcohol abuse of his mother, pneumonia, weight < 2000 g). In eight women mostly mild complications were observed, such as hypertension (n = 5), nonspecific elevation of liver enzymes (n = 2), infection (n = 3) and premature labor (n = 1). Mean gestational age was 39 wk and mean birth weight 2900 g. One case of prematurity and three cases of growth retardation occurred. Cesarean sections were performed in 7 patients (54%) for maternal hypertension (n = 2), presumed fetal hypoxia (n = 4) and breech position (n = 1). All children are normally developed, the oldest being 5 yr old. Although experience with tacrolimus is limited, pregnancies following liver transplantation carry an acceptable risk if carefully monitored by an experienced team of transplant surgeons and obstetricians.

We hypothesized that women employees working in a hospital environment would be particularly attuned to aspects of personal health, well-being, and disease prevention. We performed an observational study at a local hospital, offering free assessments in its outpatient women's wellness screening program to women employees aged 39-60 years. Data from the first 60 women to enroll in the program are presented as a test of our hypothesis. Undiagnosed hypertension, abnormal lipid profiles, glucose intolerance, alcohol abuse, abnormal cervical cytology, breast masses, depression, or combinations of these were found in 49 of the 60 women. Twenty-one women were obese. Most women with abnormal findings did not follow specific personalized recommendations for remedial follow-up, including referral to a specialist. An important percentage of midlife women employees at this hospital exhibited unhealthful personal behaviors, had unrecognized disease, and did not use recommended health screening practices. The data emphasize the benefit for employees who participate in medical facility worksite health promotion programs.

Although epidemiological studies are limited by diagnostic uncertainties, they suggest that stroke increases the risk of dementia. The mortality rate is higher in vascular dementia (VaD) than in Alzheimer's disease (AD). Community-based studies have provided several consistent findings: (i) age dependence with prevalence rates doubling every 5 years, (ii) a higher frequency in men and (iii) nation-to-nation differences. The prevalence of VaD ranges from 2.2% in 70- to 79-year-old women, to 16.3% in men >80 years. One sixth of acute stroke patients have preexisting dementia. The incidence of VaD has been studied much less extensively than that of AD, and substantial variations in the incidence rates have been observed: annual incidence rates (per 100,000) range from 20 to 40 between 60 and 69 years of age and from 200 to 700 over 80. The incidence rate of VaD declined over the last 2 decades, probably as a consequence of effective stroke prevention. It is generally assumed that risk factors for VaD are those of stroke, with arterial hypertension as leading factor, followed by atherosclerotic disease, low education level, alcohol abuse and heart disease. Stroke characteristics, such as lacunar infarction and left-sided hemispheric lesions, are major determinants of VaD. The cerebrovascular lesions are likely to be the only cause of dementia in strategic infarcts, in lacunar state, in hereditary cystatin C amyloid angiopathy and in CADASIL. However, white matter changes, and associated Alzheimer pathology, which are both frequent in this age category, may also contribute to the cognitive decline.

Chronic subdural haematomas are mainly related to slight or moderate head trauma with consecutive lesion of bridge or cortical veins and bleeding in the subdural space. Further predisposing factors are known impairment of coagulation (coagulopathies, treatment with anticoagulants, alcohol abuse), risk factors for degenerative disease of the arteries (diabetes mellitus, arterial hypertension), and development of pressure gradients (hydrocephalus, epileptic seizures, lumbar puncture, CSF drainage and cerebral atrophy). Chronic subdural haematomas appear bilaterally in 20 to 25% of cases. We report on a 69-year-old male with a 4-day history of intermittent, proximal, painless paraparesis (BMA grade M2-5) without a trigger event. Sensibility was normal in all qualities and vigilance was not disturbed. Computed tomography of the neurocranium revealed a bitemporally located chronic subdural haematoma with extension to parietal on both sides. Trepanation was performed over the tuber parietale and temporoparietally on both sides, with release of 150 ml fluid. The neurologic deficits regressed totally within 12 hours postoperatively. To the best of our knowledge, we are the first to describe the clinical paradox of intermittent, painless paraparesis with preserved sensibility and without disturbances of vigilance, as manifestation of a chronic subdural haematoma possibly leading to impairment of cerebral blood flow in the area of the middle cerebral artery. Small changes in systemic blood pressure lead to changes in cerebral perfusion pressure due to vessel compression by the haematoma, thus explaining the intermittent character of the clinical presentation.

In conclusion, surgical therapy in patients with chronic pancreatitis may be characterized as follows: 1. Independently, several investigators have found intraductal and intraparenchymatous hypertension in patients with chronic pancreatitis. Decompression of the ductal system as the main principle of surgical therapy achieves clinical pain relief in most patients with chronic pancreatitis. The precondition is a consequent drainage of the main pancreatic duct and tributary ducts of second and third order up to the prepapillary region. The presence of an inflammatory tumor in the head of the pancreas or ductal abnormalities in the prepapillary region or a pancreas divisum requires performance of an extended drainage operation (LPJ-LPHE) to achieve pain relief and an improved quality of life. An extended drainage operation effectively manages complications arising from adjacent organs, such as distal common bile duct stenosis, segmental duodenal stenosis, and internal pancreatic fistulas. The extent of decompression has to be tailored to the anatomic and morphologic situation of the patient. 2. In patients with chronic pancreatitis, the main pancreatic duct is usually dilated. A small duct (3-5 mm) is only small for the surgeon. For the sclerosing entity of chronic pancreatitis with a truly small duct, that is, less than 3 mm in diameter ("small duct disease"), a longitudinal V-shaped excision of the ventral pancreas, as opposed to left resection, provides a new perspective for a sufficient drainage. 3. In the presence of segmental portal hypertension, a simple or extended drainage operation does not result in a normalization of the portal venous blood flow; however, how often relevant upper gastrointestinal hemorrhage develops from segmental portal hypertension is unclear. Therefore, the clinical relevance of this special problem needs further evaluation. 4. Postoperative morbidity of LPJ-LPHE is significantly lower in comparison to resectional procedures, such as PD, PPPD, and DPRHP. A lower perioperative mortality rate is not justified anymore as a relevant criterion in favor of drainage procedures because resectional procedures are burdened by a minimal or no mortality in experienced centers; however, PD and PPPD are greatly hampered by a significantly decreased postoperative global quality of life as opposed to the LPJ-LPHE. This is reflected by a significantly lower rate of social and professional rehabilitation. 5. The incidence of exocrine and endocrine organ dysfunction is lower after LPJ-LPHE compared with PD or PPPD, but not compared with DPRHP. Preservation of the gastroduodenal passage and the continuity of the bile duct with its associated feedback mechanisms of exocrine pancreatic secretion and glucose metabolism seem to be responsible for this phenomenon. 6. An early surgical or endoscopic interventional drainage of the hypertensive pancreatic duct system possibly offers the chance to favorably manipulate the natural course of chronic pancreatitis with regard to a delayed onset of exocrine or endocrine insufficiency. 7. Late mortality reflects continued alcohol abuse rather than the effect of an operative procedure.

Alcohol consumption has been reported to have both beneficial and harmful effects on the incidence of stroke. Different drinking habits may explain the diversity of the observations, but this is still unclear. We reviewed recent clinical and epidemiological studies to find out whether alcohol intake could increase or decrease the risk for stroke. By a systematic survey of literature published from 1989 to 1997, we identified 14 case-control studies addressing alcohol as a risk factor for haemorrhagic and ischaemic stroke morbidity and fulfilling the following criteria: the type of stroke was determined by a head computerised tomography scan on admission or at autopsy; and alcohol consumption was verified using structured questionnaires or by personal interviews. In some studies, adjustment for hypertension abolished the independent role of alcohol as a risk factor. On the other hand, the studies covering even recent alcohol intake showed in many cases that heavy drinking is an independent risk factor for most stroke subtypes, and that the risk may decrease relatively rapidly after the cessation of alcohol abuse. In some studies, regular light to moderate drinking seemed to be associated with a decreased risk for ischaemic stroke of atherothrombotic origin. In conclusion, recent heavy alcohol intake seems to be an independent risk factor for all major subtypes of stroke. The ultimate mechanisms leading to the increased risk are unclear. The significance of alcohol as a risk factor has been demonstrated in young subjects because they are more often heavy drinkers than the elderly. Several factors to explain the beneficial effect of light to moderate drinking have been proposed.

The historical trauma response is a constellation of characteristics associated with massive cumulative group trauma across generations, similar to those found among Jewish Holocaust survivors and descendants. Trauma response features include elevated mortality rates and health problems emanating from heart disease, hypertension, alcohol abuse, and suicidal behavior. This article explores gender differences in the historical trauma response among the Lakota (Teton Sioux) and the correlation with health and mental health statistics. The theory of a Lakota historical trauma response is first explained. Traditional gender roles are described in combination with modifications engendered by traumatic Lakota history. Then, data from a study on Lakota historical trauma are presented, including gender differences in response to an experimental intervention aimed at facilitating a trauma resolution process. The data revealed significant gender differences. The sample of women presented initially with a greater degree of conscious affective experience of historical trauma. In contrast, the men reported more lifespan trauma associated with boarding school attendance and appeared to be at an earlier stage of grief. However, at the end of the intervention, women's experience of survivor guilt--a significant trauma response feature-decreased while men's consciousness of historical trauma and unresolved grief increased. Degree of traditional presentation-of-self, including phenotype, appeared to interact with gender to place male participants at greater risk for being traumatized over the lifespan and perhaps subsequently utilizing more rigid defenses against the conscious experience of the trauma with the exception of survivor guilt. The article concludes with a discussion of health and mental health implications for prevention and treatment of the trauma response which could positively impact the health status of the Lakota. Recommendations for future research are suggested.

Acute pancreatitis is a disorder that has numerous causes and an obscure pathogenesis. Bile duct stones and alcohol abuse together account for about 80% of acute pancreatitis. Most episodes of biliary pancreatitis are associated with transient impaction of the stone in the ampulla (that causes obstruction of the pancreatic duct, with ductal hypertension) or passage of the stone though and into the duodenum. Other causes of acute pancreatitis are various toxins, drugs, other obstructive causes (such as malignancy or fibrotic sphincter of Oddi), metabolic abnormalities, trauma, ischemia, infection, autoimmune diseases, etc. In 10% of cases of acute pancreatitis, no underlying cause can be identified; this is idiopathic pancreatitis. Occult biliary microlithiasis may be the cause of two thirds of the cases of "idiopathic" acute pancreatitis. Intra-acinar activation of trypsinogen plays a central role in the pathogenesis of acute pancreatitis, resulting in subsequent activation of other proteases causing the subsequent cell damage. Ischemia/reperfusion injury is increasingly recognized as a common and important mechanism in the pathogenesis of acute pancreatitis and especially in the progression from mild edematous to severe necrotizing form. Increased intracellular calcium concentration also mediates acinar cell damage. Oxygen-derived free radicals and many cytokines (e.g., interleukin [IL]-1, IL-6, IL-8, tumor necrosis factor-alpha, platelet activating factor) are considered to be principal mediators in the transformation of acute pancreatitis from a local inflammatory process into a multiorgan illness.

Many infants with intrauterine growth retardation (IUGR) are screened for TORCH infections. The yield and costs of such a practice may not be justifiable. Medical charts of infants with IUGR who had a workup for toxoplasmosis, other (infections), rubella, cytomegalovirus (infection), and herpes (simplex) (titer) (TORCH) infections were reviewed for the presence of clinical findings, laboratory and head ultrasound abnormalities associated with intrauterine infections. Maternal charts and reports of placental pathology were reviewed for identifying maternal illnesses and placental causes associated with IUGR. Seventy-five out of 182 infants (41%) with IUGR had a workup for TORCH infection. Maternal conditions associated with IUGR included: pregnancy-induced hypertension (19%), tobacco use (43%), alcohol abuse (21%), illicit drug use (24%), chronic hypertension, diabetic vasculopathy or collagen vascular disease (12%), and multiple gestation (3%). Placental pathology was available in 53/75 cases. Thirty-six of fifty-three (67%) placentae had abnormalities associated with IUGR: placental infarcts (22 of 36), vasculitis/villitis (15 of 36), placenta previa (1 of 36), abruptio placenta (2 of 36), and velamentous insertion of umbilical cord (1 of 36). Clinical findings among infants included hepatosplenomegaly, cataract or rash (1 of 75), thrombocytopenia and/or neutropenia and/or direct hyperbilirubinemia (11 of 75). Seven out of 75 infants had dysmorphic features. None of the infants (0 of 75) had positive IgM titers for toxoplasma, rubella, cytomegalovirus (CMV), or herpes simplex virus (HSV). No infants (0 of 43) had elevated total IgM titers; one infant (1 of 57) had a positive urine culture for CMV. One infant had evidence of calcifications on head ultrasound and a second infant had hydrocephalus (2 of 43). The costs associated with workup for TORCH infections among 75 infants included: TORCH titers determination: $17,816, total IgM titers: $1318, urine culture for CMV: $5734, and head ultrasound: $28,165. The yield of workup for TORCH infection among infants with IUGR is poor and does not justify the incurred costs.
