Long survival with giant cell myocarditis

Several aspects of giant cell myocarditis remain controversial, including the natural history of the disease and the nature of the giant cells. We have observed three patients who had long survival with chronic active giant cell myocarditis. The first patient was a 59-yr-old female who had a 10-yr history of complete heart block which was found at autopsy to have been caused by giant cell myocarditis. The second patient is a 36-yr-old female who received a heart transplant 5 yr after a biopsy proven episode of active myocarditis, and examination of the explanted heart revealed giant cell myocarditis. The third patient was a 41-yr-old male who received a heart transplant 2 yr after developing progressive heart failure, and the explanted heart had giant cell myocarditis. On immunohistochemical study of the three hearts, the giant cells stained with the macrophage markers lysozyme and KP-1 (CD-68). Staining of the same cells with desmin and actin was focally positive in a punctate pattern, correlating with the ultrastructural presence of myofibrils within giant cell phagolysosomes. The associated lymphocytic infiltrate stained primarily for the T-cell markers CD-3, CD-45RO, and CD-43 whereas only a few of the lymphocytes stained with the B-cell marker CD-20. The long histories of cardiac dysfunction in the three patients show that giant cell myocarditis may have a protracted course. The morphologic studies show that the giant cells are of histiocytic origin but can contain phagocytosed components of myocytes, observations that may account for the controversy surrounding the nature of the giant cells in giant cell myocarditis.     

Resting and acetazolamide-challenged technetium-99m-ECD SPECT in transient global amnesia

This report describes the case of a 42-yr-old woman with systemic lupus erythematosus who presented with septic shock. Initially, a source of infection could not be found and the patient was started on stress dose corticosteroids and antibiotics. A CAT scan revealed thickened colon and endoscopy revealed possible ischemic colitis. She soon developed peritonitis, and was taken to surgery where gastrointestinal mucormycosis was found. The patient died despite amphotericin therapy.     

Thymic abscess with bacteremia and manubriosternal pyarthrosis in a geriatric patient

We describe a geriatric patient with acute substernal chest pain thought to be due to coronary heart disease, who was subsequently found to have Staphylococcus aureus bacteremia associated with infection of the thymus and manubriosternal joint. To our knowledge, this is the first report of (1) a thymic abscess in a geriatric patient, (2) a thymic abscess associated with bacteremia, (3) extra-articular extension of manubriosternal pyarthrosis, and (4) manubriosternal pyarthrosis in the geriatric age group.     

Enterococcal bacteremia in a medical center

BACKGROUND: The enterococci have become important nosocomial pathogens. They can cause multiple site infections and enterococcal bacteremia becomes more frequently associated with a high mortality rate. Previous studies of enterococcal bacteremia showed a variety of results. To establish the significance and importance of enterococci as nosocomial pathogens in this hospital, to characterize their clinical pictures and to search for the risk factors for mortality, this retrospective study was performed. METHODS: There were 208 cases of enterococcal bacteremia which occurred from 1988 to 1992. Twenty-seven cases had no medical charts, dismissing possibility of evaluation. Finally, 181 cases of enterococcal bacteremia were analysed. RESULTS: One hundred and eighteen episodes were nosocomial infections. Polymicrobial bacteremia occurred in 68.5% of the patients and the most common co-isolate was Pseudomonas aeruginosa. Those patients (78.5%) with underlying diseases and malignancies were the most common underlying problems. The portal of entry could be found in 69.6 percent of patients, with the gastrointestinal tract the most common sources. Antimicrobial susceptibility testing showed high gentamicin resistance rate (89.5%), and ampicillin still had about 80 percent sensitivity rate. The group who received specific antibiotic therapy for enterococcus showed lower mortality (36.4% versus 47.6%). Only one case had infective endocarditis. Forty-nine patients suffered from septic shock, the cause of 30 deaths. Totally 75 patients died during hospitalization. Besides sepsis, another major cause of death was their underlying diseases itself. CONCLUSIONS: Enterococci have no doubt become important nosocomial pathogens and enterococcal bacteremia were associated with high mortality, especially in elderly patients with underlying diseases such as malignancy or diabetes. When clinically dealing with sepsis from the gastrointestinal or biliary tract, especially when previous cephalosporins therapy showed no response, the possibility of enterococcal bacteremia should always be considered.     

Strategic therapy with children: Single-subject case-study demonstrations.

Discusses 3 child therapy cases to illustrate the utility of the strategic therapy approach. Illustrative therapist–client dialogs and accompanying narration and graphics depicting child symptom reductions are included. Ss were a 9-yr-old female referred to treatment for her emotionality, a 13-yr-old female referred for night fears and insomnia, and an 8-yr-old male who was referred because he frequently argued and talked back to his mother.

Safety, efficacy, and cost of pancreaticoduodenal resection in a specialized center based at a community hospital

OBJECTIVE: To determine whether pancreaticoduodenal resection (PDR) for benign and malignant disease can be performed safely, efficiently, and economically at a 50-bed community hospital. DESIGN: Retrospective review of 39 consecutive PDRs performed in an 18-month period. Indications for surgery, length of hospital stay, complications, and patient charges were analyzed. SETTING: A suburban 50-bed community hospital. PATIENTS: Thirty-nine patients (15 male and 24 female) referred for PDR for benign and malignant disease. MAIN OUTCOME MEASURES: Mortality and morbidity rates, length of hospital stay, care, and cost. RESULTS: Of 39 patients who underwent PDRs, 1 patient (2.6%) died of myocardial infarct. Intraoperative blood transfusions were required by 3 patients (8%). The mean postoperative hospital stay was 11 days. Twenty-four patients (62%) were discharged by day 11. Fifteen patients (38%) were hospitalized 11 to 24 days. Complications in 10 patients (28%) included pancreatic or biliary fistula (n = 6), upper gastrointestinal tract bleeding (n = 1), partial wound dehiscence (n = 1), bacteremia (n = 1), and pneumonia (n = 1). No patient required reoperation. Three patients were rehospitalized within 1 month. Mean patient charges were $21,864, and mean reimbursements were $19,669. CONCLUSIONS: Pancreaticoduodenal resection can be accomplished with low morbidity and mortality rates and a short stay at a community hospital. Thorough preoperative investigations to exclude unresectable lesions must precede every PDR for malignant disease. Mortality and morbidity rates in this series were similar to those for patients with similar diagnoses who were operated on in academic centers. Cost for and length of hospital stay of these 39 patients were significantly lower than those in other reported series.     

Anesthetic managements of a patient with multiple sclerosis using propofol

We experienced anesthetic management of a 45-yr-old female patient with a 12-yr history of multiple sclerosis who underwent orthopedic surgeries three times under general anesthesia. We chose rapid induction with propofol and maintained the anesthesia with nitrous oxide, oxygen, and sevoflurane. We monitored both core and peripheral temperatures to avoid the rapid increase of core temperature, which might worsen the symptoms of the disease. There is no other report of anesthesia using propofol as induction agent for a patient with multiple sclerosis. We succeeded in the satisfactory perioperative management of the patient.     

The negative therapeutic reaction.

The negative therapeutic reaction (NTR) is a unique case of negativism in which the patient demonstrates an inability to tolerate success in treatment. This results in the deterioration of the patient's condition shortly after progress is achieved. The NTR is distinguished from either a regression that accompanies a transference neurosis or a form of negative transference in psychotherapy. It is suggested that the patient perceives her/his progress and approval by the therapist as a severe threat to the patient's autonomy. The fear of fusion with the therapist propels the patient into an extreme negativistic position that is expressed by her/his deterioration. The case is presented of a 48-yr-old female who reacted to improvement in treatment with a negative refusal to consolidate these gains and translate them into a more effective adjustment.

Seasonal cutaneous immune responses in an Antarctic wintering group: no association with testosterone, vitamin D metabolite or anxiety score

Neutropenia occurs in approximately 17% of symptomatic patients infected with HIV. Results of studies have failed to demonstrate a consistent relationship between HIV-related neutropenia and the subsequent development of bacterial infections. This was a case control study to determine if HIV-related neutropenia was associated with increased rates of bacteremia. The experimental group was comprised of 29 patients infected with HIV that had an absolute neutrophil count less than 1000 cells/mm3 and were paired with 29 control subjects infected with HIV that had been matched for age, sex, CD4 count, and month and year of entry. The frequency of bacteremia was 12.6 per 100 patient months among the experimental group compared to a frequency of 0.87 per 100 patient months among the control group (relative risk [RR] = 14.9, P = 0.0027). Other independent risks for the development of bacteremia included central venous catheters (RR = 3.9, P = 0.03), with a trend toward increased risk for bacteremia in those patients who were intravenous drug users (RR = 3.8, P = 0.11), or who had infiltrative bone marrow disease (RR = 3.1, P = 0.11). Multivariate analysis demonstrated that neutropenia (odds ratio [OR] = 22.6, P = 0.028) and the presence of a central venous catheter (OR = 8.5, P = 0.026) were significant risks for bacteremia. These data suggest that neutropenia is a significant risk for the development of bacteremia in patients infected with HIV.     

Tuberculous colitis mimicking Crohn's disease

Intestinal tuberculosis is a rare disease in western countries and may mimic a variety of gastrointestinal disorders. Here, we report the case of a 63-yr-old patient who presented with profuse bleeding from a deep rectal ulcer. Similar lesions were found in different parts of the colon. Multilocular colorectal carcinoma was suspected based on the macroscopic appearance. Histology, however, suggested Crohn's disease. Intestinal tuberculosis was initially ruled out by negative staining for acid-fast bacilli, mycobacterial culture, and polymerase chain reaction analysis. A treatment for Crohn's disease was started. Endoscopic reexamination revealed progressive disease with extensive ulcerations of the terminal ileum. Histopathological examination then revealed acid-fast bacilli in the colonic mucosa typical for mycobacterium tuberculosis infection. This case emphasizes the need to include intestinal tuberculosis in the initial differential diagnosis of ulcerative colorectal lesions also in the western population.     

Diffuse gastrointestinal angiodysplasia associated with cryptogenic hepatic cirrhosis and coagulopathy simulating von Willebrand disease

Angiodysplasic lesions can be located anywhere in the gastrointestinal tract, but most of them are found in the cecum and right colon. Angiodysplasias are very infrequent in the stomach and small bowel. These lesions can be associated with several clinical conditions, such as certain coagulation disorders and liver diseases. We report the case of a diffuse gastrointestinal angiodysplasia in a female patient with idiopathic cirrhosis of the liver who developed a coagulopathy which mimicked von Willebrand disease. After repeated blood transfusions, which were not able to control the anemia of the patient, an antrectomy was performed because most lesions were located in the antrum. The procedure did not achieve a suitable control of the bleeding. Finally, a hormonal therapy combining estrogens and progestagens, was able to control, at least partially, the patient's chronic gastrointestinal bleeding.     

Primary biliary cirrhosis associated with mixed type autoimmune hemolytic anemia and sicca syndrome: a case report and review of literature

A case presenting with an unusual association of primary biliary cirrhosis and mixed type autoimmune hemolytic anemia plus sicca syndrome is described. The 49-yr-old female primary biliary cirrhosis patient had a confirmed sicca syndrome and presented with jaundice and life-threatening anemia. Laboratory tests revealed positive Coombs' test with coexisting cold and warm autoantibodies. She was successfully treated by blood transfusion with packed red cells lacking any red cell antigens corresponding to serum alloantibodies and pulse methylprednisolone therapy. The patient remained stable under maintenance treatment using oral steroids and ursodeoxycholic acid. This case is probably the first reported showing an association between primary biliary cirrhosis and mixed type autoimmune hemolytic anemia plus sicca syndrome and was probably induced by heterogenous and complicated autoimmune reactions.     

Abdominal compartment syndrome

PURPOSE: Two cases of abdominal compartment syndrome are described and the pathophysiology associated with it is reviewed. CLINICAL FEATURES: The first patient was a 46-yr-old man who sustained extensive blunt abdominal injuries following a fall. The second was a 54-yr-old man involved in a motor vehicle accident with blunt abdominal trauma. In both cases, the patients developed an extremely tense abdomen, increasing peak inspiratory pressures, hypercarbia and oliguria. Both demonstrated improvement in cardiac performance and ventilatory variables following an emergency decompressive celiotomy. CONCLUSION: Abdominal compartment syndrome results in impairment of organ function secondary to increased intraabdominal pressure. These patients require emergency decompressive celiotomy to relieve the symptoms. However, the incidence of intractable asystole and hypotension during this procedure is high and vigilance must be maintained during the release of the increased intraabdominal pressure.     

Reliability and validity of standardized case management simulations.

Examined the reliability and validity of 3 computerized case management simulations in counseling, similar to patient management problems in medicine. The simulations depicted a 40-yr-old female with chronic back pain, a 22-yr-old female with a personality disorder, and a 51-yr-old male with alcoholism. The simulations were administered to a criterion sample of 15 experienced counseling practitioners (mean age 35.7 yrs) and to 3 additional samples (n?=?15 in each) representing high, moderate, and low levels of professional training/experience. The mean ages of these 3 groups were 27.7, 25.6, and 24.1 yrs, respectively. Alternate forms reliability coefficients were moderately high, and coefficients for composite scores based on all 3 simulations were somewhat higher. Significant relations were found between performance on the simulations and levels of training and experience. Results support the potential usefulness of standardized case management simulations in evaluating clinical problem-solving skills.

Erabulenols, inhibitors of cholesteryl ester transfer protein produced by Penicillium sp. FO-5637. II. Structure elucidation of erabulenols A and B

OBJECTIVES: To determine the risk for bacteremia, in the post-Haemophilus influenzae type b era, in a prospective cohort of well-appearing febrile children 3 to 36 months of age with no obvious source of infection; and to compare the predictive abilities of objective criteria in identification of children with occult pneumococcal bacteremia from those at risk. DESIGN: All children seen from 1993 through 1996, 3 to 36 months of age with a temperature of 39.0 degrees C or higher, no identified source of infection (except otitis media), and discharged to home were considered to be at risk for occult bacteremia and included in the study. SETTING: Urban pediatric emergency department. RESULTS: Of 199868 patient visits to the emergency department, 1911 children were considered to be at risk for occult bacteremia. Blood cultures were obtained from 9465 (79%). A total of 149 blood cultures contained pathogenic organisms, indicating a rate of occult bacteremia of 1.57% (95% confidence intervals: 1.32%-1.83%). White blood cell count and absolute neutrophil count were the best predictors for occult pneumococcal bacteremia. Using a white blood cell count cutoff value of 15 cells x 10(9)/L (sensitivity, 86%; specificity, 77%; and positive predictive value, 5.1%) would result in the treatment of approximately 19 nonbacteremic children for each bacteremic child treated. CONCLUSIONS: The prevalence of occult bacteremia in children 3 to 36 months old with temperatures of 39.0 degrees C or higher and no obvious source of infection is 1.6%. The white blood cell and absolute neutrophil counts are the most accurate predictors of occult pneumococcal bacteremia and when available should be used if presumptive antibiotic therapy is being considered.     

Septicemia occurring after colonoscopic polypectomy in a splenectomized patient taking corticosteroids

Although a transient bacteremia may occur in approximately 4% of patients after colonoscopic procedures, clinically significant bacteremia or endocarditis is exceedingly rare. To our knowledge, the case we describe herein is the first reported case of septicemia due to Flavobacterium meningosepticum and Escherichia coli after colonoscopic polypectomy. Our patient was probably immunocompromised and, therefore, predisposed to bacteremia after the procedure, because she was asplenic, diabetic, and receiving long-term steroid therapy for her chronic autoimmune disorders. Several recent reports have suggested that immunocompromised patients are more likely to develop septicemia after endoscopic procedures.     

Clostridium difficile infection is a risk factor for bacteremia due to vancomycin-resistant enterococci (VRE) in VRE-colonized patients with acute leukemia

A cohort study was conducted in a cancer center to identify risk factors for bacteremia with vancomycin-resistant enterococci (VRE) in neutropenic cancer patients colonized with VRE. There were 10 patients with VRE bacteremia among 56 colonized with VRE, of whose charts 51 were available for review. One hundred percent of patients with VRE bacteremia (10 of 10) vs. 56% of patients without VRE bacteremia (23 of 41) had acute leukemia (P = .01, Fisher's exact test). Four of the 10 patients with VRE bacteremia had a positive Clostridium difficile toxin assay within 6 days of their first positive VRE blood culture. Both C. difficile infection and antimicrobial (vancomycin and ciprofloxacin) use during VRE colonization were significant risk factors for VRE bacteremia in univariate analysis. When a Cox proportional hazards model was used to account for differences in follow-up time, C. difficile infection was the only statistically significant risk factor (risk ratio, 8.2; P = .007) for VRE bacteremia in VRE-colonized patients with acute leukemia.     

MRI of orbital hydroxyapatite implants

BACKGROUND: Serratia bacteremia is an uncommon illness in hospitalized patients. The aim of this study was to determine how frequently this disease occurs nosocomially and to discover the most common portals of entry and the underlying disorders. METHODS: Fifty-six cases of Serratia bacteremia documented by blood culture (17 cases over a 4-year period in a community hospital in Gainesville, Florida, and 39 cases over a 3-year period in three community hospitals in Dayton, Ohio) were reviewed. Comparison was made with 60 control cases of general bacteremia from three Dayton hospitals. RESULTS: Of the 56 study cases of Serratia bacteremia, 45 (80.4%) were classified as nosocomial, compared with 13 (21.7%) of the controls. Twenty-seven (48.2%) of the 56 Serratia cases occurred in intensive care units. The cases were evenly distributed over the two study periods, and no outbreaks on specific units were noted. The most common portals of entry for Serratia organisms were, in descending order, lung, genitourinary tract, unknown, intravenous line, gastrointestinal tract, and skin. The most common underlying disorder for Serratia bacteremia was malignancy, followed by renal failure (acute or chronic) and diabetes mellitus. Most of the Serratia organisms tested were sensitive to carbenicillin, trimethoprim/sulfamethoxazole, ceftizoxime, ceftriaxone, ceftazidime, cefotetan, aztreonam, ticarcillin/clavulanate, and ciprofloxacin. The organisms were largely resistant to ampicillin, tetracycline, cefazolin, cephalothin, and cefuroxime. Twenty-five percent of the patients with Serratia bacteremia died, compared with 13.6 of the bacteremic controls. CONCLUSION: Serratia bacteremia is often acquired nosocomially. The mortality rate among the study population was surprisingly low for this opportunistic bacteremia, but was higher (though not significantly so) than that of the controls.     

Amikacin therapy of gram-negative bacteremia

Treatment with amikacin was evaluated in 15 patients with gram-negative bacteremia. The sources of sepsis were urinary tract (in six patients), abdomen (in five) and miscellaneous sites (in four). Sixteen bacterial pathogens were recovered, including three gentamicin-resistant organisms. All isolates were susceptible to amikacin. Eleven of the 14 patients who could be evaluated fulfilled the criteria for cure, including the three patients with gentamicin-resistant organisms. Three patients failed to respond to amikacin therapy. Monitoring untoward effects revealed eighth nerve toxicity in one patient and nephrotoxicity in one patient. These results indicate that amikacin is effective in the treatment of patients with gram-negative bacteremia, even when caused by gentamicin-resistant bacteria.
