Here we describe a case of angina pectoris in a patient for whom an extensive cardiovascular workup was done, with negative results. Eventually, the cause of his symptoms was found to be pernicious anemia. Although angina is an uncommon manifestation of pernicious anemia, a review of the literature suggests that the correlation between anemia and angina has been well described. Our case highlights an important differential diagnosis to consider for patients with exercise-induced chest pain and serves to emphasize the attention that should be focused on simple screening laboratory studies. The emphasis in this case is the sequence in which the studies are done. A simple complete blood count with proper interpretation and intervention at the outset of evaluation could possibly have prevented a number of unnecessary, invasive, and costly studies.

Gross and microscopic findings consistent with acute (three patients) and healed (four patients) myocardial infarction were found in seven (9.7%) of 72 consecutive hearts from patients with sickle cell disease studied after autopsy between 1950 and 1982. Gross obstructive and atherosclerotic lesions were absent in all seven patients, while microthrombi were present in the arterioles of infarcted tissue in two patients. Pathophysiological mechanisms responsible for the infarction are unclear, but anemia, platelet thrombi, coronary vasospasm, and abnormal rheology related to sickle cells may all be important. Chest pain occurred clinically in six of the seven patients and ECG findings typical of infarction were found in two patients. One patient died suddenly. These findings suggest that ischemic heart disease may be present in a significant number of patients with sickle cell disease and should be considered in all patients who complain of chest pain, whether or not the patient is in crisis.

The treatment of anemia in hemodialysis patients is frequently hindered by the presence of suboptimal iron stores. Intravenous iron dextran is in common use to maintain iron stores in this population, but there are little published data regarding the incidence and type of adverse events. The purpose of this study was to evaluate the safety of this medication. Charts from four hemodialysis centers of all 573 patients treated with intravenous iron dextran (INFeD; Schein Pharmaceutical, Inc, Florham Park, NJ) between July 1, 1993, and June 30, 1995, were studied. Twenty-seven patients (4.7%) had adverse reactions that were related to iron dextran. Four patients (0.7%) had reactions classified as serious (one cardiac arrest; three others required hospitalization). Ten patients (1.7%) had reactions classified as anaphylactoid. No patients died or developed permanent disability as a result of reactions. The most common adverse reactions included itching (1.5% of patients) and dyspnea or wheezing (1.5%); others included chest pain (1.0%), nausea (0.5%), hypotension (0.5%), swelling (0.5%), dyspepsia (0.5%), diarrhea (0.5%), skin flushing (0.3%), headache (0.3%), cardiac arrest (0.2%), and myalgias (0.2%). Five of all the reactions occurred during a test dose; four of these were anaphylactoid. Several factors were studied as possible predictors of adverse reactions. A positive history of drug allergy (odds ratio, 2.4; P = 0.03) and history of multiple drug allergy (odds ratio, 5.5; P = 0.0004) were significant predictors of reactions. In summary, we found serious adverse reactions to be uncommon in hemodialysis patients treated with intravenous iron dextran. Future prospective studies will help confirm this finding.

In the period of 1989-1995 seven patients with amebic liver abscess were observed in Clinic of Infectious Diseases of Pomeranian Medical School in Szczecin. The diagnosis has been made on the base of epidemiological data, presence of intrahepatic defect by a scanning procedure of liver (ultrasonography, CT, scintigraphy) and positive serologic test for amebiasis. All patients were male of Polish nationality, 29-57 years old, who became ill after travel to Africa or India. Intestinal amebiasis was present only in two cases. Five patients had acute onset of disease and two chronic. The most common complaints included fever, abdominal pain, anorexia. A cough, chest pain, diarrhea or weight lose were less common. At physical examination paleness of skin, subjaundice, abdominal tenderness, hepatomegaly and sometimes pleural effusion have been observed. Laboratory tests revealed high RBS, leucocytosis and mild anemia. Slightly higher serum level of bilirubin, alkaline phosphatase were transient. Trophozoits of Entamoeba histolytica have been found in stool specimens of one only patient. Amebic antibodies tested with indirect hemagglutination (IHA) were present in all cases. Visual technics have shown abscess of 3 to 9 cm in diameter located at right liver lobe. Six patients have been treated with both chemotherapy (metronidazole or/and dehydroemetine) and "skin needle" aspiration. In two cases recrudescence of abscess has been observed after one and three years respectively. These two patients have been undergone second course of treatment with using not only needle aspiration and metronidazole/dehydroemetine but luminal agents as well.

Most of the lower limb surgeries are done under spinal anesthesia. This 21 year-old male had undergone open reduction with interlocking nail for his right femoral fracture and was scheduled for removal of interlocking nail. Spinal anesthesia was performed and a sensory block up to T8 level was achieved. During removing of the nail, the patient complained of chest pain, dyspnea and headache. Consequently, tachycardia and hypotension were observed. Then he coughed up pink frothy sputum. Ephedrine 5 mg was given to raise his blood pressure. About 3 min later, he recovered from the hypotension. Arterial blood gas analysis showed hypoxemia and hypercapnia. After endotracheal intubation, he was sent to surgical intensive care unit. In surgical intensive care unit, fat globules in urine, anemia and thrombocytopenia were noted. Chest roentgenogram showed patchy pulmonary infiltrates in the left lower lobe. A pulmonary artery catheter was inserted for pulmonary measurement, which read pulmonary artery pressure 45/28 mmHg, wedge pressure 14 mmHg, and cardiac output was 5-34 L/min. Supportive treatment which included steroid therapy, and O2 therapy with positive end-expiratory pressure was initiated under the impression of pulmonary embolism. The course in surgical ICU was uneventful and he left there three days later and was discharged on the fifth hospitalization day.

A cohort of 12,501 adults aged 15-54 years was randomly selected from 12 rural communities in Mwanza region, Tanzania, in 1991-92 and followed for 2 years to assess the contribution of HIV/AIDS to mortality in the region. HIV seroprevalence in the sample was 4% at baseline. 73 of the 196 deaths recorded over the period occurred among HIV-positive individuals. Mortality rates per 1000 person-years were 6.0 among the HIV-seronegative and 93.5 among the HIV-seropositive. The age-adjusted mortality rate ratio was 15.68 overall. 35% of overall mortality was attributed to HIV infection, 53% among those age 20-29 years. Verbal autopsies administered for each death reported showed that HIV-positive deaths were significantly associated with fever, rash, weight loss, anemia, cough, chest pain, abdominal pain, and headache. The specificity of individual symptoms, however, was low. The World Health Organization clinical case definition of AIDS was satisfied for only 13 deaths, of which seven were HIV-positive at baseline. HIV/AIDS was mentioned during the verbal autopsy interview by only seven respondents as being associated with a given death.

A successful surgical repair was experienced for a 75 year old female patient with ruptured dissecting aneurysm at the descending aorta. She presented with severe chest pain and advancing anemia. CT scan showed haemorrhage from the descending aorta into the pleural cavity. Diffused and circumferrential thickening of the descending aorta was shown but those area was not enhanced by dye injection. An "ulcer like formation" was shown at the descending aorta by aortogram done before surgery. Surgical repair was done subsequently by left thoracotomy with cardiopulmonary bypass. Only a small intimal wall leakage at the bottom of the crater with size of 20 mm and organized (old) thrombi were seen by intraoperative observation. Other part of intima was thickened but had no damage. Replacement was done for the descending aorta by 8 cm length with woven dacron graft successfully. Microscopic finding of resected aortic tissue showed severe atherosclerotic change. In this case, dissection was initiated from the part of crater which had most severe degeneration by atherosclerotic change and oozing started there, too. Atherosclerotic change, dissection, and oozing rupture were occurred at the same part in this patient, which is quite instructive.

Hereditary hemorrhagic telangiectasia (Osler-Weber-Rendu) disease is characterized by cutaneous, mucosal, and visceral vascular anomalies. Two patients were previously described with coronary artery aneurysms (ectasia) associated with this disease. This report describes a patient with Osler-Weber-Rendu disease in whom multiple coronary arteriovenous malformations were identified during coronary angiography. The patient presented with anginal chest pain resulting from severe anemia. Upper gastrointestinal endoscopy revealed multiple angiodysplastic lesions throughout the esophagus and stomach.

A 72-year-old patient presented himself with typical symptoms of coronary heart disease and was scheduled for invasive diagnostic procedures. Cardiac risk factors were smoking and arterial hypertension. The physical examination was inconspicious. In the laborchemistry a hemoglobin of 79 g/l with a mean corpuscular volume of 63 fl and a mean corpuscular hemoglobin of 20 pg was conspicuous. The serum iron was with 42 micrograms/dl in the lower norm. Transferrin, bili-rubin and lactate dehydrogenase were normal. Then in the gastrointestinal investigations he was diagnosed with a leiomyoma of the intestine that led to chronic anaemia and additionally to chest pain characteristic for angina pectoris. After the removal of the tumor and normalization of hemoglobin this patient was free from symptoms of the disease. The coronary angiography revealed a complex stenosis of the right coronary artery with collaterales and not significant stenosis both of the left coronary arteries. In patients with angina pectoris anaemia as the possible and only cause of angina ought to be verified. It is therefore necessary after normalization of hemoglobin and clarification of the cause for the anaemia to apply a test for coronary ischemia.

We experienced 23 cases of venous thrombosis after gynecological surgery for the past 12 years at Tokyo Women's Medical University Hospital, representing 0.345 % of all patients. Eighteen of the 23 cases had deep venous thrombosis (DVT) including five cases followed by pulmonary embolism (PE), and five cases had PE without any symptoms of DVT. The main risk factors for thrombosis in these 23 patients were (1) obesity, DM, hyperlipidemia; (2) huge abdominal tumor, severe adhesion; and (3) hemoconcentration, post-treatment of severe anemia. The onset of PE varied from 1 to 3 postoperative days, when the patients started to walk. Five cases had dyspnea, chest pain, and decreased PaO2 levels without leg pain, while five cases showed only calf pain and tenderness with decreased PaO2 levels. PE was confirmed by immediate diagnostic images such as RI venography with ventilation and perfusion lung scan, pulmonary arterial CT, or pulmonary arteriography. Two patients died and eight patients recovered. The best way of managing venous thrombosis might be as follows: (1) identify the risk factors of thrombosis before surgery; (2) perform prophylactic leg exercises in bed and/or active anticoagulant therapy depending on the degree of risk factors; (3) rapid diagnosis with the images; and (4) proper treatment.
