Deleterious effects of criminal victimization on women's health and medical utilization. The long-term consequences of criminal victimization on physical health were examined among 390 adult women (74 nonvictims and 316 victims of crime). Data included health status self-ratings and objective service utilization. Findings indicated that severely victimized women, compared with nonvictims, reported more distress and less well-being, made physician visits twice as frequently in the index year, and had outpatient costs that were 2.5 times greater. Criminal victimization severity was the most powerful predictor of physician visits and outpatient costs. Utilization data across 5 years preceding and following crime were obtained from 15 rape victims, 26 physical assault victims, and 27 noncontact crime victims and were compared with five continuous years of utilization among 26 nonvictims. Victims' physician visits increased 15% to 24% during the year of the crime compared with less than 2% change among nonvictims. We conclude that these long-term deleterious effects suggest that criminally victimized women's needs for medical treatment transcend the traditional focus on emergency care and forensic evaluation.

Predictive value of congenital hypertrophy of the retinal pigment epithelium as a clinical marker for familial adenomatous polyposis. One hundred forty-eight members of 53 kindreds with familial adenomatous polyposis (FAP) were examined for congenital hypertrophy of the retinal pigment epithelium (CHRPE) and extracolonic manifestations (ECM) to assess the value of CHRPE as a predictive marker for FAP. Based on eye examination results, the families were divided into 2 groups. In a first group of 34 families, all 61 members diagnosed as having polyps and 13 of the 33 patients at risk had 4 or more lesions distributed in both eyes. By contrast, in a second group of 18 families, all 32 polyposis patients and all 18 members at risk had less than 4 lesions. Extra-colonic manifestations were present in 26 of 34 families in the first group and in 11 of 18 families in the second group. Data on one family with ambiguous ancestry were reviewed separately. The existence of 4 or more CHRPE lesions distributed in both eyes seems to be a congenital marker for FAP, present in 65.4 percent of families. When present in a family: 1) it is found in all diagnosed patients in that family, 2) can therefore be considered predictive for the development of polyps in other family members who carry the trait, and 3) if confirmed by longer follow-up, may possibly preclude members without the trait from further evaluation and surveillance.

Adenomyomatosis of the gallbladder. A premalignant lesion? Gallbladder cancer is the most common malignant tumor of the biliary tract, but its early diagnosis is uncommon. The use of ultrasonography has increased the detection of benign gallbladder tumors, and the premalignant potential of gallbladder adenomas is now undisputed. Adenomyomatosis of the gallbladder has recently been suggested to have malignant potential, and we report a case of adenocarcinoma of the gallbladder occurring in localized adenomyomatosis that was successfully treated by radical curative surgery. The more rigorous use of ultrasonography and a more aggressive approach to "benign" polypoid lesions of the gallbladder may represent the best way of achieving early diagnosis and cure in gallbladder cancer.

Effect of a tricyclic antidepressant and opiate antagonist on binge-eating behavior in normoweight bulimic and obese, binge-eating subjects. A subset of the obese population (25-30%) has been reported to engage in binge eating at least twice weekly (bingers) and to exhibit personality traits and food attitudes similar to those of normoweight bulimic women (bulimics). Tricyclic antidepressants and opiate antagonists effectively suppress binge eating in normoweight bulimics. This 8-wk placebo-controlled, double-blind trial investigated the effect of naltrexone and imipramine on 33 obese bingers and 22 bulimics. Naltrexone (100-150 mg/d) produced a significant reduction in binge duration in bulimics (36 +/- 16%, median +/- SIQR; P = 0.02) whereas imipramine significantly reduced binge duration in obese bingers (88 +/- 31%; P = 0.02). A strong placebo effect was observed in obese bingers and, although a reduction in binge frequency occurred with both naltrexone and imipramine, it was not significantly different from the effect in placebo control subjects. We conclude that naltrexone and imipramine may be useful agents in the treatment of binge eating.

Streptococcal endocarditis temporally related to transesophageal echocardiography. A case of streptococcal sanguis endocarditis temporally related to a transesophageal echocardiogram is reported; and the literature on the incidence of bacteremia occurring during transesophageal echocardiography is reviewed. On the basis of this case and review of the literature, a reevaluation of the current guidelines for endocarditis prophylaxis during this procedure is recommended.

Rosacea and ulcerative colitis: a possible association. Although rosacea was formerly believed to be associated with gastrointestinal upsets, no one any longer finds a significant association between rosacea and the intestinal tract. We describe four patients with a combination of ulcerative colitis and rosacea. In all four, ulcerative colitis preceded the onset of severe papulopustular rosacea, and we therefore feel that the severity of rosacea could have been due to the associated bowel disorder. In one, the severity and poor initial response of rosacea to treatment was clearly related to the activity of the ulcerative colitis, and the rosacea improved only after proctocolectomy. While it is possible that this purported association is fortuitous, we report these cases in the hope that others may have seen this combination of diseases, to our knowledge previously unreported.

Upper gastrointestinal bleeding in relation to previous use of analgesics and non-steroidal anti-inflammatory drugs. Catalan Countries Study on Upper Gastrointestinal Bleeding To assess the risk of upper gastrointestinal bleeding associated with the use of individual non-narcotic analgesics and non-steroidal anti-inflammatory drugs (NSAIDs), a multicentre study of 875 cases of upper gastrointestinal bleeding and 2682 hospital controls was done. With control for confounding factors, the overall odds ratio estimate for aspirin taken at least once during the week before the first symptom was 7.2 (95% confidence interval 5.4-9.6). Non-aspirin NSAIDs associated with upper gastrointestinal bleeding were diclofenac (7.9 [4.3-14.6]), indomethacin (4.9 [2.0-12.2]), naproxen (6.5 [2.2-19.6]), and piroxicam (19.1 [8.2-44.3]). Paracetamol, propyphenazone, and dipyrone did not increase the risk. A previous history of gastrointestinal bleeding or peptic ulcer did not greatly affect odds ratio estimates, which differed according to sex and were higher for younger than for older patients. However, the incidence of upper gastrointestinal bleeding was higher among the elderly.

Iliofemoral arterial complications of balloon angioplasty for systemic obstructions in infants and children The medical and radiological records of 64 consecutive infants and children who underwent transfemoral balloon dilation of the aorta or aortic valve were reviewed to determine the incidence, nature, and post-treatment outcome of acute iliofemoral complications. Balloon dilation angioplasty or balloon valvotomy was performed with 8F and 9F catheters without an arterial sheath. Patients ranged in age from 5 days to 15.4 years (mean, 6.4 years). Of 64 patients, 29 (45.3%) had an acute iliofemoral complication, including thrombosis (18 of 64), complete disruption (five of 64), incomplete disruption (three of 64), and arterial tear (three of 64). The arterial pathology was confirmed in 23 of 29 patients by one or a combination of surgical exploration and repair (18 of 29), angiography (six of 29), and magnetic resonance imaging (three of 29). Of eight patients, three with arterial disruption had acute hypotension requiring transfusion and immediate surgery; the other five had absent pedal pulses after the procedure. Of these five, three developed bleeding during thrombolytic therapy and underwent surgical exploration, and two were diagnosed by angiography after ineffective thrombolytic therapy. Angiography in three patients with iliac artery avulsion showed tapered occlusion in two and an aneurysm in one. In patients with iliofemoral thrombosis, angiography showed occlusion from the puncture site to the origin of the external iliac artery. Eleven patients (17% of the entire group and 38% of the group with acute iliofemoral complications) had reduced or absent pedal pulses at the time of discharge. A significant correlation was found between increased incidence of iliofemoral thrombosis and disruption (as well as abnormal pedal pulses at hospital discharge) and low patient weight.

Gastric dysrhythmias following pylorus-preserving pancreaticoduodenectomy. Possible mechanism for early delayed gastric emptying. Transient delayed gastric emptying is reported as a frequent complication following pancreas-preserving pancreaticoduodenectomy (PPW). We placed serosal electrodes on the stomach of a patient undergoing PPW. Myoelectric recordings were obtained postoperatively and correlated with simultaneous radionuclide liquid gastric emptying studies. The patient developed early postoperative gastric atony, associated with frequent gastric dysrhythmias. These dysrhythmias may have been exacerbated by a perihepatic abscess. The gastric dysrhythmias correlated with alterations in liquid gastric emptying. Gastric dysrhythmias may be a mechanism for gastric dysfunction in the early postoperative period.

Pulmonary artery balloon counterpulsation for intraoperative right ventricular failure. Two cases of severe low cardiac output and right ventricular failure after coronary artery bypass grafting necessitated pulmonary artery balloon counterpulsation after intraaortic balloon pumping and maximal inotropic/pressor support were unsuccessful in maintaining a satisfactory cardiac output. Hemodynamic improvement was sufficient to allow removal of the device 2 and 3 days postoperatively, with survival in 1 patient. Pulmonary artery counterpulsation is less morbid in comparison with other mechanical methods of right ventricular support and is applicable in right ventricular failure of intermediate severity.

Increasing prevalence of gallstones in male veterans with alcoholic cirrhosis. Cases of alcoholic cirrhosis identified at necropsy were studied for the prevalence and type of gallstones, compared with age- and race-matched autopsy controls. Data were examined from 1970-1977 and 1980-1987. In the early sample of 460 cirrhotic patients, 33% had gallstone disease, contrasted with 12% in the controls. In the 1980s, among 299 patients, 46% had gallstone disease, whereas it was present in 13% of the controls. The prevalence of stones was significantly greater in the patients than in the controls for both time periods and, among the patients, was significantly greater in the 1980s than in the 1970s (p less than 0.05). A comparison of cirrhotic patients with and without gallstones indicated a significantly higher incidence of ascites in the patients with gallstones. The gallstones in cirrhotics were more frequently pigmented than in the controls in both time periods. In 100 living patients with advanced cirrhosis studied by sonography during 1987 and 1989, the prevalence of gallstones was 43%, almost the same as the autopsy sample from 1980-1987. In these cirrhotics, ascites, encephalopathy, and varices were more prevalent in the patients with stones than those without. We conclude that pigmented gallstones are increasing in cirrhosis of the liver related to the severity of the liver disease.

Physical activity, opportunity for reinfection, and sibling history of heart disease as risk factors for Chagas' cardiopathy. A case-control study was conducted to examine whether physical activity, sibling history of heart disease (HHD), and length of residence in an area endemic for Chagas' disease were associated with the risk of developing Chagas' cardiopathy. Two hundred forty-seven cases of Chagas' heart disease and 345 seropositive subjects with normal ECG (controls) were selected in a population survey in Goiania, Brazil. Prevalence ratios for exposure variables were estimated for cases in relation to controls and for subgroups of seropositives with selected ECG abnormalities in relation to controls. Increasing age and male sex were consistently and significantly related to an increased risk of ECG abnormalities. HHD was significantly associated with ECG alterations in 3 of the 5 comparison subgroups (any ECG alteration, right bundle branch block, and left anterior hemiblock). No association was found between length of residence in an area endemic, physical activity, and ECG abnormalities. A sample of 529 seronegative subjects were also examined and the interaction between exposure variables and seropositivity was tested to assess whether the associations found were specific for seropositives. Males were at greater risk of any ECG alteration and left anterior hemiblock in relation to females if they were seropositive. An increasing risk of ventricular premature beats with age was clearer for seropositive than for seronegative subjects. Subjects with HHD were at an increased risk of ECG abnormalities and this was greater in those with a positive serological test (P less than 0.05). The findings suggest a possible geographical clustering or a familial aggregation of cases of Chagas' heart disease.

Esophageal perforation during pneumatic dilatation for achalasia: a possible association with malnutrition. Pneumatic balloon dilatation of the lower esophageal sphincter is commonly utilized as primary therapy for achalasia. Perforation related to pneumatic dilatation is uncommon (2-6%) but may result in severe morbidity. Factors associated with risk of perforation are not well defined. We noted perforation in three patients undergoing forceful balloon dilatation. All these patients had clinical evidence of significant malnutrition (recent marked weight loss and severe hypoalbuminemia). Malnutrition may be a causal factor for perforation in patients with achalasia undergoing dilatation.

Lack of late skin necrosis in man after high-dose irradiation using small field sizes: experiences of grid therapy. Out of a total of 437 patients with superior vena caval syndrome or advanced malignancy, given single-dose grid radiotherapy, four survived to 7 years. The dose to the skin under each of the 77 holes in the grid was approximately 58 Gy. The lack of skin necrosis in the total of 308 skin circles of 1 cm diameter among these survivors, compared with known necrosis rates in larger irradiated areas, implies that there is a marked field-size effect for late necrosis in small areas of irradiated skin.

Spontaneous neuronal hyperactivity in the medial and intralaminar thalamic nuclei of patients with deafferentation pain. Electrical activity was recorded from single cells in the thalamus of 10 patients with chronic pain associated with deafferentation. Under local anesthesia, these patients underwent either electrode implantation or thalamotomy for treatment of their pain. In eight of the 10 patients, single units were identified as discharging spontaneously in high-frequency, often rhythmic, bursts. The discharges were of two types: short bursts comprised of two to six spikes with a burst frequency of one to four per second; and long trains of 30 to 80 spikes of similar frequency. Reconstruction of electrode trajectories indicated that recordings were made from the region corresponding to the lateral aspect of the mediodorsal thalamic nucleus, the central lateral nucleus, a small part of the central median nucleus, and the parafascicular nucleus. In the eight patients in whom spontaneous neuronal burst activity was exhibited, it was impossible to study activity evoked by natural cutaneous stimulation due to the continuous spontaneous neuronal discharges. Both animal and human studies have suggested that pain related to deafferentation is accompanied by spontaneous hyperactivity in the dorsal horn of the spinal cord and in the ventral posterior thalamic nuclei. The authors present evidence of spontaneous neuronal hyperactivity in the intralaminar thalamic nuclei of patients with pain related to deafferentation. The findings suggest that spontaneous neuronal discharge in patients with pain related to deafferentation is more widespread in the central nervous system than has been previously appreciated. The results have important implications for the surgical treatment of chronic pain.

Cognitive and behavioral effects of the coadministration of dextroamphetamine and haloperidol in schizophrenia. OBJECTIVE: The authors sought to determine if an acute dose of dextroamphetamine might have positive effects on affect and cognition in schizophrenic patients maintained on a regimen of haloperidol and, if so, what variables might predict such improvements. METHOD: Twenty-one patients with chronic schizophrenia who were hospitalized on a research ward received a single oral dose of dextroamphetamine (0.25 mg/kg) in a double-blind, placebo-controlled, crossover study. All patients were receiving 0.4 mg/kg per day of haloperidol. Cognitive tests, motor tests, global ratings, mood ratings, and videotape ratings were used to determine the effect of the coadministration of these drugs. Ventricle-brain ratios derived from CT scans were used to predict response to the coadministration of these drugs. RESULTS: Amphetamine improved performance on a measure of concept formation on the Wisconsin Card Sorting Test but did not result in changes in performance on tests of memory or attention. As a group, the patients were more active and performed psychomotor tests more quickly while receiving amphetamine. Six patients were judged by clinical raters to have improved in terms of affect, cooperation, and engagement with the environment. Improvement was associated with enlarged cerebral ventricles and increases in blink rate from the placebo to the active drug condition. No patient unequivocally worsened. CONCLUSIONS: These results may be consistent with the theory that coadministration of amphetamine and haloperidol produces relatively selective enhancement of cortical dopaminergic activity. However, because of the acute nature of the trial and the specialized research environment in which it was conducted, the authors do not advocate amphetamine as a routine clinical treatment of schizophrenia.

Excess purine degradation caused by an imbalance in the supply of adenosine triphosphate in patients with congestive heart failure. To evaluate purine degradation in patients with congestive heart failure concentrations of serum hypoxanthine, lactate, and noradrenaline were measured before and after submaximal treadmill exercise in 12 patients with chronic congestive heart failure and nine healthy volunteers. In four patients the concentration of hypoxanthine was significantly higher than in the controls or in the remaining eight patients with congestive heart failure. Venous lactate and noradrenaline in the four patients with high concentrations of hypoxanthine were also significantly higher than those in the eight patients with normal concentrations of hypoxanthine. Patients who responded normally were also more likely to have been treated with vasodilators and angiotensin converting enzyme inhibitors. Exercise induced arrhythmias were more common in the patients with high concentrations of hypoxanthine. These results suggest that the excess purine degradation in patients with congestive heart failure might be the result of a "relative" disturbance in the supply of adenosine triphosphate caused by the shift of cellular metabolism from aerobic glycolysis to anaerobic glycolysis during submaximal exercise and that hypoxanthine (a substrate for xanthine oxidase and a source of free radicals) was increased after submaximal exercise in some patients with congestive heart failure.

Spinal hemangioblastoma, syrinx, and hydrocephalus in a two-year-old child. A two-year-old child presented with an acute inability to bear weight. Radiological investigation revealed a large cervicothoracolumbar syrinx of no known cause. During investigation, acute communicating hydrocephalus developed, which required a shunt. At surgery, a small thoracic spinal cord hemangioblastoma was discovered and excised. Complete recovery with collapse of the syrinx followed. The clinical features of this rare childhood tumor and its associated effects are discussed.

Intracranial germ-cell tumors in children. All patients with confirmed intracranial germ-cell tumors treated at the Hospital of Sick Children during the period January, 1952, to December, 1989, were reviewed. Of the 51 tumors reviewed, 16 were located in the suprasellar region, 32 in the pineal region, and three in both the pineal and the suprasellar regions. Forty-nine patients underwent surgical resection which was total in seven and partial in 20, and consisted of a biopsy in 22. Two patients were managed on the basis of serum and cerebrospinal fluid markers. Surgical tools such as the operating microscope, the ultrasonic surgical aspirator, and the laser beam allowed safe debulking and removal of the deep-seated tumors in the pineal region. There were no operative deaths in the 36 patients treated since 1972, who included 23 with pineal tumors. Twenty-five patients with germinomas received radiotherapy and had a 5-year survival rate of 85.1%. Thirteen patients with non-germinoma germ-cell tumors received radiotherapy and had a 5-year survival rate of 45.5%. On the basis of this review, the authors recommend resection of pineal and suprasellar germ-cell tumors in order to firmly establish an accurate histological diagnosis to guide the extent of adjuvant therapy. In the case of a pure germinoma without evidence of dissemination, adjuvant therapy consists only of local radiotherapy. On the other hand, for malignant non-germinoma germ-cell tumors, adjuvant therapy must include chemotherapy as well as craniospinal axis radiotherapy.
