Carboplatin has been developed for clinical trials as a less nephrotoxic, less emetogenic analog of cisplatin. In preclinical tumor models it was less potent than the parent compound on a molar basis, but reduced toxicity allowed comparable antitumor doses to be given. In phase I studies its dose-limiting toxicities were reversible myelosuppression, especially thrombocytopenia. Leucopenia and anemia occurred to a lesser degree. Other reported toxicities included nausea, vomiting, malaise, myalgia, arthralgia, ototoxicity, hypomagnesemia, and proteinuria. Nausea and vomiting occurred frequently, but was much less severe than that observed with cisplatin. The incidence of serum creatinine elevations was low. The increase was usually reversible and occurred only in association with administration of aminoglycosides, or abnormal pretreatment renal function. Recommended phase II doses by schedule are: bolus every 4 weeks, 400-500 mg/m2 (560 mg/m2 in children); 24 hour continuous infusion every 4 weeks, 320-400 mg/m2; weekly bolus for 4 consecutive weeks with 2 weeks rest, 100-125 mg/m2 (175 mg/m2 in children); bolus for 5 consecutive days every 4 weeks, 77-95 mg/m2. Objective responses were observed during these phase I studies in adult patients (head and neck, breast, renal carcinomas) and children (osteosarcoma, brain stem lesions). In addition to phase II evaluations in all major tumor types, plans for phase III studies in selected tumors are underway.

A 36 year old woman was admitted to the hospital in November 1983 because of her inability to walk. For 3 months prior to admission, she took oral contraceptives (OCs) as a treatment for amenorrhea. 2 months prior to admission, she had general malaise, anorexia, and unsteady gait. 1 month before her admission, tingling and numbness began in the fingertips and spread up to the forearms, a tight feeling around the waist developed, and walking became ataxic. On admission to the hospital, she was thin and pale with greying hair. Her mind was clear and there were no abnormalities of the cranial nerves. Her extremities were hypotonic but not wasted. Slight muscle weakness of the hands and feet was noted. There was myokymia in both legs. Deep tendon reflexes of the extremities were absent. The plantar responses were extensor and lack of coordination in the extremities was noted. There was a definite glove and stocking type of hypesthesia to pinprick and cotton wool. Vibration sense was decreased below T11 and lost in both legs. There was a marked loss of position sense to passive movement in the legs and some impairment in the hands. Laboratory examination revealed mild magaloblastic anemia, elevated LDH, borderline low concentration of vitamin B12 in the serum, increased excretion of methylmalonate in the urine, achylia, positive antiparietal cell antibody and positive anti-intrinsic factor antibody. Cyanocobalamin absorption by the Schilling test was 5.6% after intrinsic factor, 11.3%. The diagnosis of pernicious anemia was made. Upper gastrointestinal studies showed typical carcinoid tumors of the stomach. Cerebrospinal fluid was normal. Peripheral nerve conduction studies demonstrated normal or slightly decreased motor conduction velocities and absent sensory action potential. Sural nerve biopsy was performed. Myelinated fibers were moderately decreased in number to 5554/mm squared and pronounced loss of large myelinated fibers was demonstrated in fiber histogram. Teased method of the single fiber showed mainly axonal degeneration. Anemia and neurologic function improved rapidly with parenteral hydroxocobalamin therapy and 1 month after treatment commenced, she was able to walk without assistance. The clinical significance of peripheral nerve involvement of subacute combined degeneration of the spinal cord was discussed, as the peripheral nerve affection is only poorly understood in contrast to the myelopathy. This was followed by discussion of the possible effect of the OCs and gastric carcinoid to neurological manifestation of pernicious anemia. (author's modified)

A 62-yr-old woman, admitted to Mitsui Memorial Hospital with complaints of jaundice, general malaise and anorexia, was diagnosed as acute hepatitis A by positive IgM anti-HA. On the 13th hospital day, indirect hyperbilirubinemia (total bilirubin 57 mg/dl, indirect bilirubin 38.5 mg/dl) and splenomegaly were noted. Hemoglobin concentration decreased to 8.4 g/dl and reticulocytes increased to 6%. Bone marrow showed hyperplastic marrow with erythroid hyperplasia. Coombs test was negative. After administration of prednisolone 40 mg daily for 30 days, hemoglobin concentration increased to 11.9 g/dl and total bilirubin was decreased to 0.4 mg/dl. The liver biopsy specimen obtained on the 62nd day, revealed recovery stage of acute hepatitis. Jaundice with increased indirect bilirubin, anemia with reticulocytosis, elevated plasma hemoglobin concentration and predominance of LDH1 were indicative of hemolysis. The enzyme activities in the red blood cells, which were taken 1 year after the onset, were within normal limits. Scanning electron microscopy of the red cells showed no significant abnormalities in their shape and the nature of the surface.

6 patients with amyotrophic lateral sclerosis were treated with intravenous infusion of 100-200 million IU per day of human leukocyte interferon. Side effects of treatment included fever, chills, malaise, nausea, marked leukopenia, mild anemia, and thrombocytopenia. Tiredness, confusion, papilledema, and overall signs of acute encephalitis were observed. Tendon reflexes and muscle force decreased. EEG activity was slowed, and evoked potentials showed significant slowing of conduction times. Neuropsychological tests revealed congitive dysfunction. The syndrome of inappropriate antidiuretic hormone secretion developed in all patients. All side effects were reversible with cessation of interferon treatment.

A Tegafur suppository of 750 mg was administered daily to 20 patients with bladder tumors, whose ages ranged from 43 to 84 years (average age 63.7). Histological study revealed transitional cell papilloma in 6 cases, transitional cell carcinoma in 12 cases, squamous cell carcinoma in 1 case and malignant tumor with extensive necrosis in 1 case. The result of staging and grading was as follows: 8 cases of pTa, 5 cases of pT1, 9 cases of pT2, 1 case of pT3a, 2 cases of pT3b and 1 case of T4; an, 6 cases of G0, 6 cases of G1, 5 cases of G2, 2 cases of G3 and 1 case of unknown grade. According to Saitoh and Koyama's criteria, no cases showed complete response (0%), 5 cases partial response (25%), 3 cases minor response (15%), 10 cases no change (50%) and 2 cases progressive disease, making the total effective rate 25.0%. Some side effects were observed in 6 of the cases (30%): General malaise in 4 cases (20%), loss of appetite in 3 cases (15%), diarrhea in 1 case (5%), edema in 1 case (5%), anemia in 2 cases (10%), an elevation of both GOT and GPT in 1 case (5%) and thrombocytopenia in 1 case (5%). A recovery from these side effects was achieved after discontinuing the use of Tegafur suppositories.

The pathogenesis and clinical signs of Haemonchus longistipes infection were studied in four experimentally infected camels two of which were adults and the other two were young. In the former animals, an acute infection developed, characterized by mucoid diarrhoea, anorexia, anaemia, loss of body weight, oedema of the lower parts of the limbs, general malaise and death at 8-10 weeks post-infection. In the two younger camels, a less dramatic disease was encountered with less severe symptoms and no oedema, but also terminating fatally at 19-20 weeks post-infection. Parasitological, haematological and biochemical parameters were determined during the course of the infection and were mostly comparable with those usually encountered in haemonchosis of other animals.

Acute febrile neutrophilic dermatosis (ND) consists of the abrupt onset of red, tender, cutaneous plaques on the face, extremities, and upper trunk, accompanied by fever, malaise, and neutrophilic leukocytosis. Histologically, there are distinctive, dense, dermal infiltrates of neutrophils. Response to systemic steroids is dramatic. This report describes four patients with leukemia or preleukemia and ND (LND), reviews reports of 12 similar patients, and compares LND with ND in otherwise healthy individuals (idiopathic ND, IND). Although lesions of LND more frequently had vesiculobullous appearances or location on mucous membranes, this study showed no consistent difference between LND and IND with regard to cutaneous signs, symptoms, histologic findings, and response to therapy. The first episode of LND either preceded or followed documentation of the myeloproliferative disorder, and the most common associated hematologic conditions were acute myeloid or myelomonocytic leukemia. Moderate to severe anemia was present in nine of ten patients whose first episode of LND preceded the discovery of the hematologic condition by eight months or less. The presence of anemia is the most obvious and readily detectable difference between LND and IND. The possibility of an underlying myeloproliferative disorder should be considered in all patients with ND, and LND should not be confused with infectious complications in patients known to have myeloproliferative disorders.

Based on the findings of 50 patients with infective endocarditis, 37 affecting the aortic, six the mitral and seven both the aortic and mitral valves, in addition to analysis of predisposing factors, prominent signs and symptoms distinctive for the clinical entity were assessed (Tables 1 to 3). Preexistent conditions such as aortic valve lesions including bicuspid aortic valve as well as mitral valve lesions including mitral valve prolapse were proven in 66%. Factors which may have compromised host defense mechanisms such as cachexia and chronic alcohol or intravenous drug abuse were present in isolated cases. In 38% of the patients, a diagnostic or therapeutic manipulation, suspected to have given rise to the bacteremia, antedated the onset of endocarditis. Malaise, fatigue and chills were the most frequent symptoms (Table 4). Fever and cardiac murmurs were observed in all patients, anemia and bacteremia in 74% of the patients, respectively (Tables 4 to 6). In blood cultures, the most common microorganisms were found to be hemolytic and nonhemolytic streptococci accounting for 65% of positive findings, followed by enterococci and gram-negative bacteria each with 14% respectively (Table 6). Congestive heart failure predominated among cardiac complications with its occurrence in 84% of the patients. Valvular ring or myocardial abscess, aortic or sinus of Valsalva aneurysm, occasionally with perforation, were found in 24% of our patients. Coronary embolism was documented in 6%; infection-associated pericarditis was observed only rarely (Table 7). Extracardiac complications involved the skin, central nervous system, spleen and kidneys, respectively, in 20 to 30% of the patients. Complications afflicting the eyes, lungs, gastrointestinal tract and the musculo-skeletal system were seen with a lesser frequency of 0 to 12% (Table 8). The diagnosis of infective endocarditis, rendered highly-probable by the constellation of fever, cardiac murmur, bacteremia and anemia, necessitates, however, confirmation through cardiac examinations. In this respect, electrocardiographic and radiologic findings are of limited value, although they may be useful in the detection of cardiac complications. In 6% of the patients, positive criteria for myocardial infarction were indicative of coronary embolism and, i 30%, atrioventricular or fascicular block suggested the presence of abscess formation (Table 9). As radiologic evidence of heart failure, 74% of the patients were found to have pulmonary vascular congestion (Table 10).(ABSTRACT TRUNCATED AT 400 WORDS)

In a medical out-patient clinic, over a period of several years, atrial myxoma was diagnosed in four patients with ages ranging between 32 and 69 years. With the exception of one patient referred for assessment of ventricular premature beats, presentation was not primarily attributable to cardiac causes. In all patients, there was a latency period of years between the onset of symptoms and establishment of the diagnosis. The history of patients with atrial myxoma includes symptoms such as dizziness, syncope, transient cerebral ischemia, weight loss and malaise. The differential diagnosis may encompass consideration of neoplastic disease since laboratory findings can reveal evidence of an inflammatory reaction, accelerated sedimentation rate, anemia, abnormal electrophoresis, hypoproteinemia as well as elevated alkaline phosphatase. One patient had undergone numerous examinations to rule out the presence of malignant disease. Symptoms related to the cardiovascular system include exertional dyspnea, premature beats, tachyarrhythmias and nonspecific chest pain. Auscultatory findings are consistent with those of mitral stenosis. M-mode and two-dimensional echocardiography established the diagnosis in all patients and confirmed the usefullness of this examination technique in the assessment of patients in a general medical clinic.
