Fifteen Indian patients with relapsing or drug-refractory visceral leishmaniasis were retreated for 30 days with antimony plus interferon-gamma (IFN-gamma). All 15 had failure of an initial course of antimony and at least one additional course of antimony or pentamidine; 7 patients had failure of three or four prior courses of therapy. During the study, treatment was discontinued in 2 patients because of anemia and congestive heart failure in 1 and intractable vomiting in the other; both subsequently died. In the remaining 13 patients, IFN-gamma plus antimony treatment was associated with daily fever but no other adverse reactions. After 30 days of therapy, 9 (69%) of the 13 patients were apparently cured. Six months after treatment, all 9 were healthy, had parasite-free bone marrow aspirate smears, and were considered cured. None have relapsed during a mean follow-up of 15.9 +/- 1.7 months. These results support the use of antimony plus IFN-gamma as an immunochemotherapeutic alternative for kala-azar patients who have repeated failures of conventional treatment.

We report three cases of histologically verified systemic amyloidosis with polyneuropathy. Common to them were early onset progressive peripheral sensorimotor disturbance starting in the legs and prominent autonomic dysfunctions such as postural hypotension, anhidrosis, and loss of pupillary light reflexes. Other characteristic features included vomiting, alternating diarrhea and constipation, opacities of the vitreous bodies, and congestive heart failure. All these clinical manifestations resemble type I familial amyloid polyneuropathy described by Andrade in 1952 from Portugal. Sural nerve biopsy stained with Congo red showed typical green birefringence under polarized light microscope. Histologically verified familial cases of this form of amyloid polyneuropathy have not been reported from Taiwan before.

Pheochromocytoma is a catecholamine secreting tumor originating from the adrenal medulla (up to 90%), or from the chromaffin tissue along the paravertebral sympathetic chain. The hallmark of pheochromocytoma is paroxysmal hypertension associated with diaphoresis, headache, tremulousness, and palpitations. The triad of diaphoresis, tachycardia, and headache in hypertensive patients is highly suggestive of pheochromocytoma. Other symptoms like flushing, nausea, vomiting, personality changes, and visual disturbances may however cast doubt on the diagnosis of pheochromocytoma. Death resulting from pheochromocytoma is usually due to congestive heart failure, myocardial infarction, or intracerebral hemorrhage. Although less than 0.1 percent of patients with hypertension have a pheochromocytoma, nearly 50 percent of the mortality with unsuspected pheochromocytoma occurred during anesthesia and surgery or parturition. Patients of unsuspected pheochromocytoma have higher risk for surgery, because some mandatory pre-op medical treatments might have been ignored. It is also a challenge to anesthesiologists to handle unsuspected hypertensive crisis during anesthesia and surgery. We presented such a case of unexpected Pheochromocytoma which was mis-diagnosed by the surgeon and was treated as an ordinary adrenal gland tumor and was scheduled for surgical operation. When the patient was undergoing excision of the tumor, manipulations of the tumor initiated an tremendous elevation of the blood pressure. Upon reviewing her history of normotension with visual disturbance, nausea and restlessness, she was immediate treated as with a pheochromocytoma. Appropriate managements were applied to control her abnormally high fluctuating blood pressure with success and with no complications or adverse effect.(ABSTRACT TRUNCATED AT 250 WORDS)

The medical records of 101 dogs with acute pancreatitis, diagnosed on the basis of medical histories of acute vomiting, with serum lipase or amylase activity greater than the reference range, or with gross signs of pancreatitis at surgery or histopathologic evidence at necropsy, were evaluated to identify potential risk factors for the development of acute pancreatitis. Age, sex, and breed of dogs with acute pancreatitis were compared with those from a reference population of 100 dogs admitted for other medical emergencies during the same period. Analysis of multiple regression models indicated that dogs > 7 years old were at increased risk for acute pancreatitis. Spayed dogs and castrated male dogs had an increased risk, compared with that of sexually intact males. Similarly, terrier and nonsporting breeds appeared to be at higher risk of developing acute pancreatitis than were other breed types. Most dogs in this study (63/101) had intercurrent diseases, including diabetes mellitus (n = 14), hyperadrenocorticism (n = 12), chronic renal failure (n = 8), neoplasia (n = 17), congestive heart failure (n = 6), and autoimmune disorders (n = 5). Fourteen dogs had undergone anesthesia or surgery in the week before admission; only 3 had undergone abdominal procedures. Recent medication use was listed in 52 of 101 cases. Antibiotics (n = 18) and corticosteroids (n = 18) were most frequently described. Anticancer chemotherapeutic agents (n = 5) and organophosphate insecticides (n = 5) also were listed.(ABSTRACT TRUNCATED AT 250 WORDS)

Ninety-three evaluable patients with metastatic breast cancer previously treated with chemotherapy, received mitoxantrone as a single agent (14 mg/m2, by rapid intravenous infusion, once every 3 weeks). Patients received a median of 7 courses (range 2 to 18), with a mean cumulative total dose of 133 mg (range 36 to 342). A complete response (CR) was achieved in 2 patients (2%). Partial response (PR) was observed in 23 patients (25%). The overall response rate (CR+PR) was thus 27%, with a median duration of 9 months (range 3 to 18). Responses were observed in all metastatic sites, except for brain and peritoneum. Stabilization (S) occurred in 26 patients (28%). The remaining 42 patients (45%) showed clear progression of their metastatic disease while on therapy. The actuarial 24-month survival for the whole group was 13%, increasing to 29% in responders (CR+PR), as compared with only 10% for non-responders (S+P; P < 0.0001). Mitoxantrone was generally well tolerated; nausea, vomiting and hair loss were mild. Nine out of 625 treatment cycles resulted in leukopenic fever with uneventful recovery. All patients had serial MUGA scans; 3 patients (cumulative total doses of 200, 250 and 342 mg, respectively) developed a significant drop in the left ventricular ejection fraction. Clinical evidence of congestive heart failure was observed in one patient who had received prior doxorubicin-based adjuvant chemotherapy. Mitoxantrone seems to be as effective as other drugs given singly or in combination as second-line chemotherapy in patients with metastatic breast cancer. Its low morbidity makes its use attractive in this setting.

The activity of single-agent paclitaxel (Taxol; Bristol-Myers Squibb Company, Princeton, NJ) has been documented in untreated and previously treated metastatic breast cancer, including both patients with anthracycline-resistant disease and those with extensive pretreatment. Such activity has prompted investigations of the optimal doses and schedules of paclitaxel/doxorubicin combinations. With one exception, paclitaxel has been administered as either a 24- or a 3-hour infusion, while the administration times for doxorubicin vary from bolus injection to 72-hour infusion. Results of these completed phase I and II trials are reviewed. Also reported are two European trials that have achieved promising results. In Milan, a phase I/II trial has shown a preliminary response rate exceeding 90% in 32 chemotherapy-naive patients treated with an alternating schedule of paclitaxel given over 3 hours and intravenous bolus doxorubicin. At doses of paclitaxel 200 mg/m2 and doxorubicin 60 mg/m2, the dose-limiting toxicities were neutropenia, oral mucositis, myalgias, and peripheral neuropathy. Congestive heart failure occurred in six patients. A phase I/II study of a 30-minute doxorubicin infusion preceding a 3-hour paclitaxel infusion every 3 weeks in minimally pretreated patients also is reported. Of 29 patients evaluable for response, 17 have achieved partial responses and seven complete responses, for an overall response rate of 83% (95% confidence interval, 79% to 99%). Toxicities observed were grades 3 to 4 neutropenia and moderate paresthesias, nausea/vomiting, alopecia, myalgia, and mucositis. Cardiotoxicity also occurred, as 15 patients had a significant decrease in left ventricular ejection fraction measured by isotope cardiography. Six of these developed congestive heart failure. This effect has been observed only in studies using short infusions of both drugs, and it is now being investigated whether lowering the peak doxorubicin concentration will preclude it.

We have carried out a phase II trial to evaluate the efficacy and toxicity of a combination therapy consisting of mitoxantrone 10 mg/sqm i.v. on day 1, levo-leucovorin 250 mg/sqm administered over 2 hours and 5-fluorouracil 500 mg/sqm i.v. push after the first hour of levo-leucovorin infusion, on days 15-16 (MFL) in patients aged more than 65 years. 24 patients with advanced breast cancer entered the study: 16 aged 65-70 yrs, 4 patients 70-75 yrs, and 4 > 75 yrs. Median PS was 1 (range 0-2); sites of metastases were: bone 14 patients, viscera 14 patients, soft tissue 11 patients, and CNS 1 patient. A median number of 6 cycles (range 3-9) was administered. All patients were evaluable for response and toxicity; partial response was obtained in 12 (50%) patients (95% C.I 30-70), stable disease was observed in 9 patients (37.5%), while 3 patients (12.5%) progressed. Median progression-free survival and survival were 9 months (range 2-14) and 14 months (range 5-36), respectively. Toxicity was generally mild and the most frequently observed side-effects were WHO gr. 1-2 leukopenia in 6/24 (25%) patients and gr. 1-2 emesis in 10/24 (41.6%) pts. 1 patient pretreated with doxorubicin cumulative dose of 240 mg/sqm showed clinical signs of congestive heart failure (NYHA grade 1) after the fifth cycle of treatment. MFL is a well tolerated regimen and could represent a safe and effective treatment in older advanced breast cancer patients.

Paclitaxel (Taxol; Bristol-Myers Squibb Company, Princeton, NJ) is active against advanced breast cancer and anthracycline-resistant breast cancer. We assessed the efficacy and toxicity of doxorubicin followed by a 3-hour infusion of paclitaxel in women with advanced breast cancer. Participants could have received at most one prior adjuvant chemotherapy regimen, but no previous exposure to anthracyclines or taxanes was permitted. The patients were treated every 3 weeks with doxorubicin (50 or 60 mg/m2) followed 30 minutes later by paclitaxel (155, 175, or 200 mg/m2). After reaching the maximum cumulative doxorubicin dose, treatment could be continued with paclitaxel alone. Thirty women were included, of whom 29 were evaluable for response. The overall response rate was 83% (95% confidence interval, 64% to 94%), with 24% of patients attaining complete remission. Median response duration for complete responders was 8+ months (range, 4 to 13 months) and median time to progression was 9 months (range, 2 to 18 months). Main toxicities were neutropenia, paresthesia, nausea/vomiting, alopecia, myalgia, and cardiotoxicity. In 15 patients (50%), the left ventricular ejection fraction decreased to below normal levels; six patients (20%) developed congestive heart failure. In conclusion, the combination of doxorubicin and paclitaxel is highly active; dose-limiting toxicities are neutropenia, neuropathy, and cumulative cardiotoxicity.

Ischemic hepatitis can occur as an acute episode in advanced congestive heart failure (CHF). The mechanism is massive necrosis of the central lobules resulting from acute hypoxia when low cardiac output further reduces oxygen supply, aggravating underlying congestion due to poor venous outflow. We describe a 70-year-old woman with congestive heart failure for 7 years who was admitted with jaundice, vomiting, abdominal pain and oliguria after an episode of hypotension. The diagnosis of ischemic hepatitis was established by a documented episode of severe hypotension, followed by elevation of serum transaminases, a rise in serum bilirubin and LDH levels, prolonged prothrombin time and acute renal failure. Other causes of acute hepatitis, such as a virus or drugs were excluded, and improved liver and renal function followed hemodynamic stabilization. We conclude that ischemic hepatitis should be considered whenever acute hepatitis follows a recent episode of systemic hypotension, especially in the context of concomitant CHF.

It has been shown that the elderly, and certain other groups, may have atypical clinical presentations of acute MI. It is important for the clinician to educate patients about the common atypical symptoms that may be experienced with an MI, such as dyspnea, fatigue, nausea, vomiting, and syncope. The clinician must always rule out acute MI in any patient who presents with these symptoms, or who presents with falls, sudden weakness, or worsening CHF. In order to treat patients aggressively and with the greatest benefit (i.e. thrombolytics or other reperfusion therapy), we must teach our patients and ourselves to recognize "silent" MIs. This will decrease the morbidity and mortality rates of acute MI in the elderly.
