Abstract
Even this information is only partial. To study fully the effects of treatment would require optimal care at all points from time of injury, including rapid prehospital resuscitation, rapid transport to an optimally equipped and staffed hospital, immediate evaluation and treatment of the initial injury and all complications, rapid and comprehensive rehabilitation, and supportive and flexible home and work settings for the patient on discharge. Patients would need to be stratified for premorbid characteristics, including intelligence, personal traits, and training. Prolonged follow-up, possibly for several years, would be required to determine true outcome. No current study contains sufficient numbers of patients treated optimally and studied for prolonged periods, but this should be done. One way of looking at such patients is to decide that many should be treated to salvage a few. The other way of looking at them is that so many must receive care, at great emotional and economic cost to themselves and others, that such treatment is inappropriate for any of them. Treating all such patients would be a major undertaking. If most of these patients were treated vigorously, a great proportion of them would still die but probably not for a number of days. During this period, their families would be under extreme stress. Once stabilized and receiving ongoing care, some patients would enter a permanent vegetative state and survive for prolonged periods until their prognosis was clear and care was withdrawn, again causing family stress as well as high cost. Some would likely survive although impaired. The charges and real costs of care for all these patients would be tremendous. The question therefore arises as to how to decide what to do about caring for a large group of patients whose maximal care would be costly in emotional and financial terms, particularly at a time when it is recognized that resources for medical care are going to be limited. When discussing such patients as a group with a view toward developing practice guidelines, many considerations must be brought to bear. One consideration is the certainty of the prognosis in both a quantitative and a qualitative sense in an individual case. It is not clear that one can be certain in patients except when there are overwhelmingly unfavorable features. As has been noted, even patients who have been shot through the geographic center of the brain and are posturing can make excellent recoveries. This would push toward aggressive treatment for many patients. Decision making must therefore be considered in terms of bioethics. The major principle-based systems of bioethics are deontologic, arising from accepted principles, and utilitarian, arising from effect on outcome. A virtue-based ethic for physicians arising from "the caring bond and the public trust" is being revived as a balance to analytical ethics. A similar orientation from the point of view of patients is communitarian ethics, that is asking for only what is reasonable and not so much as might harm others. Some of the issues to be considered include the sanctity of life while taking into account the criteria for life--vegetative function versus some level of mental function. One must also review each decision from the viewpoints of all the parties involved--patients, family and friends, physicians, and society--in the context of a heterogeneous society in which individual rights and tolerance enforced by law are primary features. In the patients' terms, there is a desire and right to medical care to maintain a healthy productive life. Even if impaired to some extent, patients may still have an interest in living. Balancing benefits and burdens of life is a complex problem. There is also the right, based on patients' values, to refuse care if there is the wish not to take a chance of having a significantly compromised existence. Such declaration before injury should be honored...

Abstract
The literature reveals several ominous trends in firearm injuries in the United States. The crack epidemic of the mid-1980s, the increasing availability of handguns and more lethal weapons, and, particularly in Southern California, the rise of gang violence have all contributed significantly to this trend. Although the crack epidemic seems to have abated, the weapons it produced and the criminal elements it encouraged are still around. Many public health experts have advocated gun control as a means to stop this violence, and they have several compelling examples to justify their efforts. Gun control, however, is beyond the scope of this article. Neurosurgeons can have some effect at the local level on gang violence, however. The University of Southern California Department of Neurological Surgery has been working with the Think First Organization and Community Youth Gang Service Organization to reach out to children before they become involved with the gangs. These organizations are also working with the justice system to reform young people already involved with gangs. The hope is that these patterns of violence can be arrested on the community level.

Abstract
Continued elevations in Intracranial Pressure (ICP) following traumatic or ischemic compromise are known to cause markedly increased morbidity and mortality. Because of the side effects of barbiturates including hypotension and prolonged recovery time, the use of shorter-acting anesthetic agents to control ICP has been considered. Etomidate, when administered by continuous infusion, has been shown to decrease cerebral metabolism resulting in a secondary decrease in cerebral blood flow with minimal changes in cerebral perfusion pressure. We initially intended to randomize 20 patients prospectively into a study protocol that would assess the effects of either pentobarbital or the cardioprotective agent etomidate on ICP and cardiac performance. Given the sequelae of the therapy, we were only able to randomize seven patients with cerebral edema refractory to medical management to receive either etomidate or pentobarbital in a blinded fashion. Three patients who received etomidate developed renal compromise (mean low creatinine clearance 41 ml/min, range 37-44 ml/min) which was initially noted at 24 hours. We believed that this represented an adverse effect that was probably related to the study drug and the study was stopped. Each patient received a 0.30 mg/kg IV induction of etomidate and then 0.02 mg/kg/min continuous infusion for 24-72 hours titrated burst suppression. All patients also received dexamethasone 2 mg IV every six hours to prevent the adrenocortical insufficiency that might occur as a consequence of etomidate-induced suppression of cortisol synthesis. Intracranial pressure decreased (mean = 12mmHg) following the initiation of etomidate. Cardiac parameters remained unchanged (cardiac output 4.8 +/- .6 liters/min).(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
A 1-month-old infant with a Dandy-Walker malformation underwent the placement of a ventriculoperitoneal shunt to treat progressive hydrocephalus. On the initial computed tomographic scan, a subependymal cystic lesion larger than 1 cm in diameter was noted in the head of the right caudate nucleus, which enlarged to 3 cm in diameter on follow-up imaging studies over the course of a year. Biopsies taken at the time of fenestration failed to show the presence of neoplasia. This appears to be the first reported case of a cyst of this nature to show progressive enlargement.

Abstract
With the continued use of bone marrow transplantation in the treatment of malignancies, immunodeficiencies, and some metabolic diseases in children, it remains important for the dermatologist to be aware of the clinical and diagnostic features, and pathophysiology of Graft vs. Host disease. Specifically, the dermatologist should keep in mind that the skin is a primary site for involvement in this process. Recognition of the spectrum of cutaneous disease, its methods of laboratory diagnosis, and treatment should be known to those physicians caring for patients undergoing this type of therapy. A brief review of these and other aspects of Graft vs. Host disease is presented in this report.

Abstract
In an attempt to evaluate the response of patients who have low admission Glasgow Coma Scale scores (GCS) after a penetrating craniocerebral injury to aggressive management, we evaluated a series of 190 patients with penetrating injuries who presented with a GCS score of 3, 4, or 5 during a 6-year period. Entrance criteria required replicable neurological examinations that were not altered by the presence of hypotension, drugs/toxins, or systemic injury. The surgical patients included 21 patients with an admission GCS score of 3, 24 with an admission GCS score of 4, and 15 with an admission GCS score of 5. All patients underwent surgical intervention and aggressive perioperative management in the neurosurgical intensive care, including resuscitative protocols. Five of the patients with a GCS score of 3 survived, all with poor outcomes. Seven of the patients with a GCS score of 4 survived, although only one had a good outcome. Eleven of the patients with a GCS score of 5 survived. Five had a Glasgow Outcome Score of 2, five had a Glasgow Outcome Score of 3, and one had a Glasgow Outcome Score of 4. We have devised a prospective model of outcome based on our series in an attempt to predict nonsurvivors at admission (while overpredicting for survivors). The variables most predictive of mortality include admission GCS score and subarachnoid hemorrhage in one model and admission GCS score and pupillary changes in a second, when pupillary response was definitive at admission (P < or = 0.00005).(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Epidermolysis bullosa (EB) represents a group of rare hereditary mechanobullous disorders marked by blister formation following relatively minor trauma. There are three categories depending on the site of disruption within the skin: simplex (above the basement membrane), dystrophic (below the basement membrane), and junctional (at the lamina lucida). Laryngeal involvement is rare, but has been reported primarily in association with junctional EB. Presented is our experience with 5 children with EB who demonstrated laryngeal involvement. Three children required tracheostomies acutely and 1 died of airway obstruction. One patient, with the Dowling-Meara type of EB simplex, was treated conservatively with good results. Tracheostomy should be an early consideration in the management of these patients to protect the airway in the acute setting and to prevent any further laryngeal injury associated with endotracheal intubation. The rate of complications of tracheostomy appears to be low; however, the prognosis for decannulation is poor.

Abstract
D-2-Hydroxyglutaric aciduria was documented in a newborn who presented with seizures, hypotonia, cortical blindness, a movement disorder, and developmental delay. Her clinical presentation differs from that of patients with L-2-hydroxyglutaric aciduria and a single previously reported patient with D-2-hydroxyglutaric aciduria. Cerebrospinal fluid levels of gamma-aminobutyric acid were elevated, while biogenic amine metabolites were normal. The movement disorder in our patient and in those with L-2-hydroxyglutaric aciduria suggests involvement of the basal ganglia in the disease process. Prenatal diagnosis of an affected fetus was accomplished during a subsequent pregnancy.

Abstract
A paucity of formally described information is available in the scientific literature regarding spinal subdural empyema. Patients presenting with neurological deterioration associated with subdural empyema are rarely identified, and treatment is often based upon anecdotal cases. The authors contribute three cases of primary cervical spinal subdural empyema and review the seven found in the literature. All patients had clinical evidence of neurological compromise, cervical tenderness, cervical pain, and leukocytosis upon admission. Cervical involvement ranged from C-2 to C-7. All patients underwent laminectomy with durotomy and drainage. The authors recommend prompt surgical decompressive laminectomy, copious irrigation, and drainage, followed with appropriate adjunctive antibiotic therapy for treatment of these patients.

Abstract
We prospectively and retrospectively reviewed a series of 780 patients who presented to the University of Southern California/Los Angeles County Medical Center with a diagnosis of gunshot wound to the brain during an 8-year period. Of these, 105 were children ranging in age from 6 months to 17 years. Injuries were gang related in 76 (72%) children and adolescents. Stepwise linear regression analysis was used to formulate a predictive model of outcome in this population. Patient age (F = 10.92), sex (F = 9.32), occipital entry site (F = 8.17), bihemispheric injury (F = 8.50), and admission Glasgow Coma Scale (F = 69.91) were all found to correlate with outcome (P < 0.05). Significant differences between pediatric and adult populations were noted in transit time, entrance site, and age-related outcome. Occipital or assassination-type wounds were most common in children. In addition, a younger age was associated with poor outcome (P < 0.0001). We describe both the economic and racial trends in our population of patients in addition to weapon type and toxicological evaluation. The Department of Neurological Surgery is becoming directly involved in providing information to children at the junior high school level regarding gang activity and brain and spinal cord injury. In conjunction with the Community Youth Gang Services Organization and Think First Organization, we are attempting to integrate prevention through education and community mobilization. This is a plan aimed at informing and recovering the youth affected by gangs.

Abstract
The use of the beta-agonist dobutamine in combination with hypervolemic preload enhancement of cardiac performance was analyzed in 23 patients who failed to respond to traditional preload enhancement following aneurysmal subarachnoid hemorrhage. The patients ranged in age from 13 to 82 years, and three had a history of cardiac disease. Each patient underwent placement of a flow-directed balloon-tipped catheter and the following measurements were obtained during hyperdynamic therapy: pulmonary artery wedge pressure, central venous pressure, cardiac index, stroke volume index, total peripheral resistance, and left ventricular stroke work index (LVSWI). Mean baseline cardiac function was found to be within normal limits (LVSWI = 47.6 +/- 4.2 gm/min/sq m and cardiac index = 3.30 +/- 0.22 liter/min/sq m). After baseline measurements were recorded, 5% albumin was infused at 300 cc/hr and dobutamine was initiated at a rate of 5 to 10 micrograms/kg/hr. This hyperdynamic therapy with dobutamine in the presence of volume loading resulted in a 52% increase in cardiac index, a 15% increase in LVSWI, and a 21% decrease in total peripheral resistance. The clinical reversal of ischemic symptoms due to subarachnoid hemorrhage was evident in 18 (78%) of the 23 patients.

Abstract
Subcutaneous fat necrosis of the newborn (SCFN) alone is an uncommon condition. Its association with hypercalcemia has been reported in 19 neonates since 1926. The two occur in full-term to postterm newborns with perinatal complications associated with delivery. Erythematous to violaceous, firm, subcutaneous nodules appear approximately 1 to 4 weeks after delivery, preceding the development of signs and symptoms of hypercalcemia. Although SCFN and hypercalcemia are rare complications in neonates with perinatal problems, death due to the sequelae of hypercalcemia occurred in 3 of the 19 patients. A neonate who develops skin lesions consistent with SCFN should be followed for possible onset of hypercalcemia and treated in a timely fashion.

Abstract
Certain clinical factors are considered to have an effect on patient outcome after penetrating missile injury. These include bilateral hemispheric injury, ventricular hemorrhage, intracerebral hemorrhage, mass effect, and missile or bony fragmentation. The relationship of subarachnoid hemorrhage (SAH) after penetrating craniocerebral injury and outcome is unknown. In addition, controversy exists regarding the role of angiography and the incidence of traumatic intracranial aneurysm in this population. Finally, can we assume that the incidence of traumatic intracranial aneurysm is equal in military and civilian populations, given the absence of penetrating shrapnel injury in civilian populations? Now that computed tomography has supplanted angiography as the primary diagnostic modality, increasing vigilance on the part of the physician and examination of angiography in high-risk patients should allow for enhanced outcome. We evaluated 100 patients with a diagnosis of cerebral gunshot wound over a 12-month period. All patients were evaluated neurologically at the time of admission and had imaging studies. Thirty-one patients with radiological evidence of SAH on computed tomography underwent angiography. Angiograms were limited to the side of the injury in patients with single-lobe or unilateral multilobe injuries and were bilateral in patients with bilateral hemispheric involvement. One intracranial aneurysm (3.2%) was documented and treated surgically. In those patients who died within 48 hours of admission, 68% had SAH as compared with only 17% of those surviving. Outcome was based upon neurological evaluation at the time of discharge and at the time of clinical follow-up at 3 and 6 months.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Cutaneous hemangiomas are common benign tumors of infancy that only rarely are associated with malformations in other tissues or organs. We report nine infants with large facial hemangiomas who also had Dandy-Walker malformations or similar posterior fossa abnormalities. On the basis of the experience with our patients and with those previously reported, we recommend radiographic imaging studies of the brain of infants with large, aggressive facial hemangiomas to rule out posterior fossa defects.

Abstract
Tinea capitis, the most common fungal infection in children, is rare in neonates. We report six patients in a Level II intermediate care nursery who developed nosocomial dermatophyte infections caused by Microsporum canis. The investigation, which led to the identification of a nurse as the common source, is described. The nurse had an indolent infection with M. canis. Human to human transmission is exceedingly rare for M. canis. The literature regarding neonatal dermatophyte infections is discussed in relation to the reported outbreak.

Abstract
This article reviews the essential clinical and pathologic features of a number of tumors of the dermis and epidermal appendages to help improve the clinician's skill at formulating preoperative differential diagnoses, assessing the need for treatment, and determining appropriate follow-up. In addition, it attempts to alert the practitioner to a number of heritable and systemic conditions that may be signalled by the presence of cutaneous tumors.

Abstract
We examined the relationships between specific magnetic resonance imaging features and certain gross and microscopic characteristics of meningiomas, including vascularity, gross texture (consistency), and venous sinus involvement. Magnetic resonance imaging scans, surgery reports, and the histopathological findings of tumors were examined retrospectively in 54 patients. Sinus involvement was accurately predicted on T1-weighted images in 9 of 10 cases (P = 0.001) and tumors with cystic changes in 3 of 3 cases. T1-weighted images were not useful for predicting vascularity unless actual flow voids could be visualized (five of six cases). There was no correlation between T1 signal intensity, tumor consistency, or histological findings. In tumors without detectable vascularity on T1-weighted images, hyperintensity relative to gray matter on T2-weighted images was correlated with increased vascularity (P = 0.004). Tumors with soft consistency (P = 0.007), cellular atypia, invasion, angioblastic, or melanocytic components were also hyperintense, compared with gray matter on T2-weighted images (P = 0.0266). Aggressive meningiomas were found to be more vascular (P = 0.045). No correlation was found between the degree of surrounding edema or contrast enhancement with histopathological findings, vascularity, or consistency.

Abstract
Radiation-induced tissue damage in the central nervous system is a well-known complication of interstitial brachytherapy for brain tumors, yet imaging correlates have historically been based upon computed tomographic scans. We now present magnetic resonance imaging (MRI) to correlate radiation changes after interstitial brachytherapy with the histopathology. The central nervous system of a 38-year-old man with a left frontal cerebral glioma diagnosed by stereotactic biopsy was treated with interstitial brachytherapy (iridium-192, 47 Gy), followed by limited-field irradiation (45 Gy). With progressive deterioration, a second biopsy demonstrated radiation changes. Despite aggressive medical management, the patient died 9 months after completion of radiation therapy. Postmortem evaluation compared MRI scans of the intact, fixed brain with the histopathology. Axial sections (10 mm) obtained by MRI scan and autopsy brain slices were cut in the identical plane. Neuroimaging and histopathological findings of the lesion correlated within 2 to 3 mm resolution. In the peripheral white matter, MRI scan did not indicate the extent of radiation effect histologically. We suggest that MRI has limited utility in assessing the extent of impact of radiation on surrounding brain.

Abstract
BACKGROUND Chickenpox, the primary infection caused by the varicella-zoster virus, affects more than 3 million children a year in the United States. Although usually self-limited, chickenpox can cause prolonged discomfort and is associated with infrequent but serious complications. METHODS To evaluate the effectiveness of acyclovir for the treatment of chickenpox, we conducted a multicenter, double-blind, placebo-controlled study involving 815 healthy children 2 to 12 years old who contracted chickenpox. Treatment with acyclovir was begun within the first 24 hours of rash and was administered by the oral route in a dose of 20 mg per kilogram of body weight four times daily for five days. RESULTS The children treated with acyclovir had fewer varicella lesions than those given placebo (mean number, 294 vs 347; P less than 0.001), and a smaller proportion of them had more than 500 lesions (21 percent, as compared with 38 percent with placebo; P less than 0.001). In over 95 percent of the recipients of acyclovir no new lesions formed after day 3, whereas new lesions were forming in 20 percent of the placebo recipients on day 6 or later. The recipients of acyclovir also had accelerated progression to the crusted and healed stages, less itching, and fewer residual lesions after 28 days. In the children treated with acyclovir the duration of fever and constitutional symptoms was limited to three to four days, whereas in 20 percent of the children given placebo illness lasted more than four days. There was no significant difference between groups in the distribution of 11 disease complications (10 bacterial skin infections and 1 case of transient cerebellar ataxia). Acyclovir was well tolerated, and there was no significant difference between groups in the titers of antibodies against varicella-zoster virus. CONCLUSIONS Acyclovir is a safe treatment that reduces the duration and severity of chickenpox in normal children when therapy is initiated during the first 24 hours of rash. Whether treatment with acyclovir can reduce the rare, serious complications of chickenpox remains uncertain.

Abstract
Cefaclor is an oral semisynthetic cephalosporin that is popular in the treatment of infections in children. This drug has been associated with a serum sickness--like reaction characterized by an urticarial eruption, pruritus, arthritis, and/or arthralgias. We report 12 additional cases of cefaclor-related serum sickness--like reactions in children. All patients improved after discontinuation of the drug and no long-term complications resulted.

Abstract
A wide variety of disorders involving the scalp and hair exist that may be encountered in the pediatric and adolescent population. An approach to the differential diagnosis of many of these conditions can be considered once the patient is found to have either alopecia, scaling, or tumors of the scalp. Certainly other causes of scalp or hair disease exist but the more common disorders can be appropriately considered in this manner.

Abstract
The effect of hypervolemic preload enhancement on cardiac performance was systematically analyzed in nine patients following aneurysmal subarachnoid hemorrhage. The patients ranged in age from 34 to 63 years, and none had a history of cardiac disease. Each patient underwent placement of a flow-directed balloon-tipped catheter and the following measurements were taken during hypervolemic therapy: pulmonary artery wedge pressure (PAWP), central venous pressure (CVP), cardiac index (CI), stroke volume index (SVI), and left ventricular stroke work index (LVSWI). After baseline measurements were recorded, hetastarch or plasmanate was infused intravenously at 300 cc/hr. Thermal output determination and pressures were measured every 15 minutes. The PAWP did not correlate in a statistically significant fashion with the CVP in the ranges recorded; however, a statistically significant correlation did exist between PAWP increases and increases in CI, SVI, and LVSWI (p less than 0.01). There was no statistical correlation between PAWP increases above 14 mm Hg and improvement in cardiac performance as evidenced by CI, SVI, and LVSWI measurements. It is concluded that CVP is an unreliable index of cardiac performance during hypervolemic therapy and that, in previously healthy individuals, a PAWP of 14 mm Hg is associated with maximum cardiac performance.

Abstract
A retrospective analysis was performed on all aneurysms operated on by one of us (SLG) from July 1980 to October 1988 to determine the factors that govern outcome from the intraoperative rupture of aneurysms. A total of 276 consecutive surgical procedures for 317 intracranial aneurysms produced 41 perioperative or intraoperative ruptures for analysis. Five cases were pre-exposure ruptures, 3 of which occurred during anesthetic induction. Four of these patients died, and 1 made a good recovery. Of the remaining 36 cases, outcome was analyzed in terms of the adjuncts used to deal with the intraoperative rupture. There was no statistically significant difference in outcome between those cases in which tamponade was used to control hemorrhage versus temporary clipping; however, those cases in which hypotension was used did less well than those in which it was not used. From October 1986 to October 1988, 108 operations for 132 aneurysms were performed without the use of induced hypotension. There were 16 intraoperative ruptures (14.8%). All 16 of these patients made a good recovery. In the group before 1986, of which there were 20 intraoperative ruptures (of 168 operations, 11.9%), 11 of those 20 patients suffered a permanent deficit or died. We conclude that hypotension may not be a necessary adjunct to the management of intraoperative rupture of aneurysms.

Abstract
Management of craniopharyngiomas and masses affecting the third ventricular chamber represents one of the most challenging problems confronting contemporary neurological surgeons. Given the devastating sequelae of surgical complications involved in approaches to the deep cerebral midline, surgical management requires a combination of sophisticated imaging, diagnostic pathology and surgical technique including ventricular microsurgery and stereotaxy and its attendant refinements. Surgical and non-surgical management is based upon the structural presentation of these masses as defined by detailed imaging studies. Operative objectives include histological definition, maximally feasible excision, cerebral spinal fluid diversion and relief of neurologic deficits created by masses affecting the third ventricular chamber.

Abstract
A case of pyoderma gangrenosum (PG) in a 14-year-old boy with acute myelogenous leukemia (AML) is described. The onset of pyoderma gangrenosum coincided with the relapse of AML. The lesions responded dramatically to treatment with oral prednisone despite the persistence of leukemia. Pyoderma gangrenosum should be included in the differential diagnosis of any nodular, pustular, or necrotic cutaneous eruption in children with leukemia.

Abstract
A distinctive photodermatitis developed in 22 children who had been receiving naproxen for prolonged periods. The eruption was marked by erythema, vesiculation, or increased skin fragility characterized by easy scarring of sun-exposed skin. Results of biochemical studies for porphyria were normal, and other causes of photosensitivity were believed to be unlikely. Of the 22 patients, 21 had juvenile rheumatoid arthritis; one patient had systemic lupus erythematosus. Twenty of the patients had fair skin and blue eyes. In each case, all findings except scarring resolved when naproxen was discontinued. Attention must be paid to complaints suggesting photosensitivity in children receiving naproxen.

Abstract
Intestinal morphology and fluid and electrolyte transport were examined in a neonatal porcine model of cryptosporidiosis. Sections of jejunum, ileum, and colon were obtained for morphometric analysis on days 3, 6, 9, and 12 postinfection, and in vivo perfusion studies of jejunum and ileum were conducted on days 3 and 4 postinfection. The most severe morphologic lesion was seen in the ileum on day 3, and consisted of villous atrophy, crypt hyperplasia, and cellular infiltration. Villous surface area was reduced from 2.1 +/- 0.4 x 10(5) microns2 in control ileum to 0.8 +/- 0.1 x 10(5) microns2 in infected ileum, a result associated with enterocytes that were fewer in number and reduced in cross-sectional area. Conversely, the number of inflammatory cells in the lamina propria of the villus increased from 456 +/- 116 in control to 1014 +/- 187 in infected villus without a significant change in the volume of the lamina propria. At the height of infection, there was an approximate 1:2 ratio of both organisms and inflammatory cells to villous enterocytes. In contrast, organisms were not observed in the crypts, and the concentration of inflammatory cells in crypt lamina propria was unaltered. Disappearance of organisms and polymorphonuclear cells from the ileum was associated with restoration of normal structure and was complete by day 12. Although organisms were seen in the colon, the general architecture was not severely affected. On days 3 and 4 postinfection, there was a complete impairment of the glucose-stimulated Na and water absorption in both jejunum and ileum of infected pigs; however, absorption of electrolytes and water from a basic Ringer's solution, in the absence of glucose, was not significantly affected. These results are consistent with a malabsorptive diarrheal disease associated with the morphological damage and are very similar to those seen in enteric viral disease in pigs, except that the upper intestine is more severely affected in the latter.

Abstract
The authors discuss a comprehensive management program for patients with cerebral vasospasm following subarachnoid hemorrhage in which therapeutic manipulation and meticulous monitoring of a number of physiologic determinants of cardiac function are employed. Ventricular preload is most significantly affected by hypervolemic therapy, but alternate methods of reversing ischemic neurologic deficits with various inatropic agents are discussed also.

Abstract
PURPOSE To describe and characterize the association of hereditary cutaneous lichen amyloidosis with multiple endocrine neoplasia type 2a (MEN 2a). DESIGN Survey of a family for two diseases. SETTING Evaluation of patients at a clinical research center. PATIENTS Nineteen family members with MEN 2a. MEASUREMENTS AND MAIN RESULTS In this family cutaneous lichen amyloidosis presented as multiple infiltrated papules overlying a well-demarcated plaque in the scapular area of the back (right or left). Immunohistochemical studies showed amyloid that stained for keratin but not calcitonin. Three family members had the characteristic skin lesion and also carried the gene for MEN 2a; two additional members carried the gene for MEN 2a, but did not manifest the observable skin changes associated with lichen amyloidosis. CONCLUSIONS From the findings in this kindred and in another recently reported but unrelated family with an identical type of pruritic skin rash and MEN 2a, several conclusions can be drawn. First, the syndrome of cutaneous amyloidosis and MEN 2a is a clearly defined autosomal dominant hereditary syndrome. Second, the dermal amyloid appears to be caused by deposition of keratin-like peptides rather than by calcitonin-like peptides. Third, known families with hereditary lichen amyloidosis should be screened to determine the true frequency of this syndrome.
