[Morphological characteristics of the internal organs of experimental animals after administration of different doses of chanerol].

Experiments were conducted with rats and dogs to study the influence of different hanerol doses on the condition of anumber of internal organs. The drug was introduced in a single dose: to rats in the form of a 0.1% solution in amounts of 6, 8, 10, 13, 20 and 30 mg/kg and to dogs as a 0.1% solution in doses of 24 mg/kg. Doses of 20 and 30 mg/kg for rats and 24 mg/kg for dogs proved intolerable and animals perished in consequence of circulatory disturbances (blood effusion, thrombosis of capillaries in the lungs, spleen, suprarenals and in organs of the gastro-intestinal tract). On application of doses amounting to 6 and 13 mg/kg in rats and 6-12 in dogs the animals remained alive, although the lungs, testes and the spleen were found to be afflicted with thrombosis of individual capillaries and there was demonstrable the the development of pneumosclerotic foci, atrophy of spermatogenic epithelium and slight splenic infarctions.

Role of splenectomy in living-donor liver transplantation for adults.

BACKGROUND/AIMS: Splenectomy is occasionally required in liver transplantation. However, its indications and drawbacks have not been clearly defined in living-donor liver transplantation. METHODOLOGY: Eleven of 59 adult living-donor liver transplantation recipients underwent splenectomy. Indications were thrombocytopenia in 6 cases, portal flow disturbances due to splenorenal shunt in four, and splenic infarction in one. The incidence of bacterial complications and changes in platelet counts and portal vein flow were evaluated. RESULTS: Two patients died of pneumonia and cerebral bleeding, respectively. Six events of bacterial infections occurred in the remaining nine patients. After splenectomy, a normal portal flow was achieved and the platelet count significantly increased. CONCLUSIONS: Splenectomy may be an acceptable option in patients with thrombocytopenia or when it is necessary to change the portal flow.

[Hemorrhagic pseudocyst of the pancreas with spontaneous rupture of the spleen].

A case of hemorrhagic pseudocyst of the pancreas in a young male, 33 years of age, heavy drinker is reported. The cyst was closely attached to the posterior wall of the stomach. Partial damage of the stomach wall resulted in subserosa hematoma. There was also rupture of the spleen, on its diaphragma surface there were many small vesicles like herpetic eruption. This indicates that the rupture took place slowly for several days.

[A case of infective endocarditis with multiple embolic complications].

A 13-year-old girl was admitted to a hospital because of fever and sore throat. Staphylococcus aureus was obtained on blood culture, and she was treated with antibiotics under the diagnosis of sepsis and DIC. Echocardiography showed huge vegetation attached to the posterior leaflet of mitral valve and severe mitral regurgitation. CT scan revealed multiple heterogeneous high density areas in her brain. She was transferred to our hospital for further examination and treatment. Large verrucae on the mitral valve, severe regurgitation and repeated embolism urged us to the emergency mitral valve replacement. Debridement of abscess on the posterior wall of the left atrium and ventricle necessitated patch plasty of those structures and mitral ring as well. Operative and postoperative examination showed mycotic aneurysm of right coronary artery, multiple brain hemorrhage, arterial obstructions of extremities and splenic infarction. Sooner she recovered except for slight macular degeneration caused by retinal embolism.

[Infective endocarditis with a huge mitral vegetation related to atopic dermatitis and high serum level of infection-related antiphospholipid antibody: a case report].

A 24-year-old woman with atopic dermatitis was admitted to our hospital with fever. Echocardiography showed a huge vegetation attached to the posterior mitral commissure without mitral valve dysfunction. Blood culture identified methicillin-sensitive Staphylococcus aureus. The serum level of antiphospholipid antibody was elevated. A splenic infarction occurred on the second hospital day. Surgery to resect the residual mobile vegetation was performed uneventfully on the 6th hospital day. The postoperative course was uneventful, and the patient was discharged after 4 weeks of antibiotic therapy. Preservation of the mitral valve is rare in the face of virulent Staphylococcus infection and the presence of a huge mobile vegetation. These findings were apparently related to the high serum level of infection-related antiphospholipid antibody and atopic dermatitis.

The complications of infective endocarditis. A reappraisal in the 1980s.

BACKGROUND: The frequency of complications of infective endocarditis and their influence on the outcome of the patients changed in the antibiotic era. Therefore, we evaluated the complications in a recent large series of patients with infective endocarditis. METHODS: We studied 300 episodes of endocarditis in 287 patients in a tertiary cardiology referral center. Predisposing cardiac conditions were valvular heart disease in 147 episodes, congenital heart disease in 37, other heart diseases in five, and prosthetic heart valves in 69. In 69 episodes, there was no previous heart disease. The infecting microorganisms were streptococci in 147 episodes, Staphylococcus aureus in 59, Staphylococcus epidermidis in 14, gram-negative bacteria in 16, other gram-positive bacteria in eight, and fungi in four. In 52 episodes, blood cultures were negative. Seventy-eight patients (26%) died. Complications were defined as any clinically unfavorable event occurring during treatment. RESULTS: A total of 386 complications occurred in 223 episodes (74%); one complication occurred in 128 episodes (57%), two in 57 (26%), three in 18 (8%), four in 13 (6%), five in three (1%), and six or more in three (1%). The complications were as follows: cardiac, 100 occurrences; neurological, 72; septic, 46; associated with medical treatment, 41; renal, 27; extracranial systemic arterial embolism, 16; septic pulmonary embolism, 26; complications related to surgical treatment, 11; acute prosthetic heart valve insufficiency, six; splenic infarction or abscess, three; cardiac rhythm disturbances, three; and other, 19. The distribution of the complications relative to outcome of the patients revealed that fatality exceeded survival rates for neurologic and septic complications. CONCLUSIONS: Complications may be common in patients with infective endocarditis. Cardiac complications were the most common ones, but fatality rates were higher for neurologic and septic complications. Hence, heart failure was replaced by neurologic and septic complications as the leading causes of death in patients with infective endocarditis.

[Therapeutic efficacy of balloon-occluded retrograde transvenous obliteration in the treatment of gastric varices in cirrhotic patients with gastrorenal shunt].

BACKGROUND/AIMS: Rupture of gastric varices was one of the most dreadful complications of cirrhosis. Recently, a new interventional procedure, balloon-occluded retrograde transvenous obliteration (B-RTO) was introduced for the treatment of gastric variceal bleeding. This study was performed to evaluate the therapeutic efficacy of B-RTO in the treatment of gastric varices with gastro-renal shunts. METHODS: From March 2000 to June 2003, we performed B-RTO in 17 patients with gastric varices and gastrorenal shunts. All patients had history or high risk factors of gastric variceal bleeding. For the evaluation of therapeutic efficacy, we performed esophagogastroduodenoscopy (EGD) and computed tomography (CT) at 1, 6 and 12 months after B-RTO. Successful B-RTO was judged by combined CT findings and EGD findings (disappearance of gastric varices or markedly reduced gastric variceal size or bleeding risk) during follow-up periods (1-14 months, mean:6.18). We analyzed the clinical factors related to clinical success of B-RTO. RESULTS: Technical success were achieved in all patients except one (94.1%). Gastric varices were disappeared or decreased after B-RTO in 13 patients (81.2%). Complications related to procedure included transient hematuria (n=5), puncture site oozing (n=1) and partial splenic infarction (n=1), and all were conservatively managed. During the follow up periods, neither significant hepatic nor renal functional damages occurred. Statistically, no significant factors related with B-RTO success. CONCLUSIONS: B-RTO is effective and safe in the management of gastric varices in cirrhotic patients with gastrorenal shunt.

Rocky Mountain spotted fever at Koair Children's Hospital, 1990-2002.

The reported average annual incidence of Rocky Mountain spotted fever (RMSF) in Kentucky is less than 5 per million population, although seroprevalence studies suggest that exposure to Rickettsia riskettsii, the causative agent, is relatively common among children. The experience with RMSF at Kosair Children's Hospital over a 12-year period was reviewed. Fifteen cases were identified (5 boys and 10 girls). Illness onset ranged from April to October, and 4 patients resided in Jefferson County. The classic triad of fever, rash, and headache was present in only 60% of cases, and tick attachment was reported in only 40%. On average, 6 days elapsed from onset of symptoms to initiation of appropriate antibiotic therapy. One patient suffered splenic infarction and necrosis of the digits due to shock and disseminated intravascular coagulopathy, and 2 patients died. RMSF is a significant cause of pediatric morbidity and mortality in this region of Kentucky. Affected children may reside in relatively urban parts of the state. Initial clinical features may be nonspecific. This, as well as decreased awareness of disease and (unjustified) reluctance to use doxycycline may contribute to delays in initiating therapy.

[Vascular complications in infectious endocarditis. Apropos of 86 cases].

During a 20 year period, 285 patients were hospitalised for infectious endocarditis (IE) in the Department of Cardiology of the Ernest-Conseil Hospital in Tunis and 86 of them, i.e. 30%, developed a vascular complication (VC). Among these 86 patients, there were a total of 108 lesions, including 52 neurological complications, 14 peripheral acute ischemic syndromes, 16 peripheral arterial aneurysms, 9 aortic aneurysms, 7 pulmonary embolisms, 6 splenic infarctions and 4 coronary lesions. The mortality in this patient group proved to be slightly greater than in the series as a whole, in particular concerning patients with multiple lesions and those with an artificial valve. No prognostic difference was seen between patients with a VC of aneurysmal type and of ischemic type, but the presentation and severity of lesions was very variable. The vascular complication was a presenting feature of IE in almost 40% of cases. The organism found most often was the streptococcus, above all in ischemic type IE as well as in the total patient group. Similarly, the preferential site was aortic, above all for aneurysmal type IE. Ultrasonography revealed a higher incidence of vegetations in this series of patients, above all in ischemic type VC, but anatomical studies have shown this to be an investigation of moderate sensitivity and poor specificity, poorly correlated from a prognostic standpoint with the risk of embolism. The conclusion of the study is above all the need to prevent such complications: embolic complications by early antibiotic treatment and valve replacement and aneurysmal complications by methodical routine angiographic evaluation and appropriate treatment.

Polycythemia in diabetic patients on CAPD.

Polycythemia in CAPD patients has been rarely described. Over an eight year period, 4 out of 123 CAPD patients (3%) were identified as having Hct values exceeding 50% for 1 month or longer. All of the 4 patients were insulin dependent diabetics (4/47 diabetic patients, 8.5%). Charts were reviewed on 3 of these 4 patients. Polycythemia developed after a mean of 21 +/- 7 months on peritoneal dialysis. Prior to the development of polycythemia, ferritin levels were low and ferrous sulfate therapy was begun at a time the Hct values were 36 to 40%. Erythropoietin levels were obtained in 2 patients, and were 22 U/L (Hct 51%) and less than 5 U/L (Hct 55%). Renal ultrasound failed to show renal masses or cysts. One patient had a plasma volume of 2.1 L (normal 2.4-3.2 L); another patient was clinically volume depleted. Complications during the period of polycythemia included gangrenous feet requiring amputation in 2 patients, CVA in 2 patients, and splenic infarct in 1 patient. One patient died of cerebral thrombosis. We conclude that polycythemia is uncommon in CAPD patients and occurs most often in diabetic patients. Volume depletion and iron therapy may play a role in its etiology. In this high risk group of patients polycythemia may contribute to vascular complications and should be avoided.

Thrombotic complications during L-asparaginase treatment for acute lymphocytic leukemia.

We report 2 new cases of thrombosis occurring in a cohort of 21 consecutive patients with acute lymphocytic leukemia treated with L-asparaginase (L-ase), 6,000 U/die s.c. or i.m. days 15-21 from start of chemotherapy, according to the GIMEMA LAL 0288 protocol. The first patient died of massive diffuse thromboembolism (thrombosis of sagittal sinus and of suprahepatic veins and pulmonary arteries; multiple hepatic and splenic infarctions) associated with markedly reduced levels of protein C, antithrombin III and plasminogen. In the second patient, portal vein thrombosis developed soon after the completion of L-ase. Antithrombin III was reduced, whereas protein C level was normal. Therapy with fresh frozen plasma and subcutaneous calcium heparin (12,500 U twice daily) proved successful, and 8 days later abdominal echotomography revealed the complete disappearance of the thrombus. The incidence of thrombosis is similar to that previously found in a cohort of consecutive patients treated at our Department with a different schedule and dosage of L-ase administration, and similar to that reported in previous series.

Scintigraphic findings in Gaucher's disease.

Gaucher's disease involves the liver, the spleen, and the bone. Liver-spleen and bone scintigraphy were used during an 8-yr period to evaluate changes caused by this disease. Patients were investigated with a liver-spleen scan for abdominal pain, mechanical discomfort, enlarged liver or spleen on physical examination, abdominal mass, abnormal liver function tests, and symptoms of hypersplenism. Fourteen liver-spleen scans were performed in nine patients. Liver scintigraphy showed various degrees of enlargement and inhomogeneous uptake. In two patients focal defects were detected. In one, focal defects were due to liver involvement with Gaucher's disease, but in the other they were caused by metastatic pancreatic carcinoma. The study was also useful in detecting splenic infarction and in following enlargement of the spleen after partial splenectomy. The main indication for bone scintigraphy in six patients was bone pain. This was found to be caused by either aseptic necrosis of the head of the femur, bone infarction, pathological fractures, or osteomyelitis. Loosening after total hip replacement was ruled out in three patients and missed in one patient. Scintigraphy appears to be a simple, sensitive test for evaluation of the liver, spleen, and bony skeleton in patients with symptomatic Gaucher's disease.

Myeloproliferative disorders.

Myeloproliferative disorders result from monoclonal proliferation of the pluripotential hematic precursor cell, with preservation of its capacity to differentiate and mature into functional progeny. Phenotypic expression varies with the degree of involvement of each derivative cell type and the extent to which growth is hyperplastic, dysplastic, or malignant. Hyperplastic bone marrow with increased circulating erythrocytes and platelets, reactivation of hematopoiesis in long bones and extramedullary sites, and the development of secondary marrow fibrosis are responsible for complications of thrombosis, hemorrhage, splenic infarction, hypersplenism, and anemia. A predilection for the geriatric population, chronicity, and great variability in phenotypic expression present a challenge in diagnosis and management. Individualized treatment based on thorough understanding of the pathophysiology of myeloproliferative disease is required to maximize complication-free survival by avoiding both the risk of the disease and its therapy and utilizing all available supportive measures in the prevention and treatment of complications.

Focal splenic disease demonstrated by ultrasound and computed tomography.

Twenty-five patients with focal splenic disease were analyzed retrospectively to determine the relative strengths and weaknesses of ultrasound and computed tomography (CT) in the detection and analysis of focal splenic lesions. Lesions were detected in all 25 patients by ultrasonography and in 22 of 25 patients by CT. Ultrasonography appears to be more sensitive in the detection of focal lymphoma within the spleen and may be slightly more sensitive in the detection of microabscesses. CT may offer more specific information regarding the nature of certain lesions, including the detection of cyst wall calcification, gas within an abscess, and the specific site of origin of tumor invading the spleen. Ultrasonography may at times be more specific in the diagnosis of cystic lesions. We recommend ultrasonography as the first method for splenic imaging with CT used when necessary for further characterization of focal lesions.

Greater curvature gastroplasty. Follow-up at 34 months.

This retrospective study analyzes the results of 198 consecutive greater curvature gastroplasties performed in 23 male and 175 female patients with morbid obesity. The gastroplasty consisted of the creation of a 30-50 cm3 proximal gastric pouch by a double application of the TA-90 stapler, modified by removing three staples near the pin and trimming the cartridge to prevent crushing of the stomach at the outlet. The outlet was calibrated to a diameter of 1 cm and reinforced with a polypropylene seromuscular suture. No deaths occurred; postoperative complications included 32 superficial wound infections (16.2%), 24 incisional hernias (12.0%), 15 staple-line disruptions (7.6%), seven gastric outlet obstructions (3.5%), five subphrenic abscesses (2.5%), three perforations (1.5%), one splenic infarction, and one enterocutaneous fistula. One hundred sixty-one (81%) patients have been followed for a mean of 34 months (range 24 to 56 months); their mean weight loss is 36.4 per cent +/- 32.9 per cent of excess body weight. Only 45.5 per cent of these patients can be considered to have had satisfactory weight loss. Because this is not as effective as other forms of surgical therapy, the authors do not recommend greater curvature gastroplasty for the treatment of morbid obesity.
