Forty-seven patients with chronic stable angina pectoris entered a thirteen-week open-label study with a transdermal therapeutic system of nitroglycerin in order to evaluate its clinical efficacy, safety, and patient acceptance. In 19 patients, a beta-blocker and in 17 patients a calcium-channel blocker were continued throughout the study period without alteration of their doses. The study consisted of a two-week run-in period and an eleven-week active drug period. Acute titration was done with nitroglycerin patches on the basis of weekly patient diaries on frequency of angina and sublingual nitroglycerin consumption. Overall, reductions in frequency of angina and in nitroglycerin consumption were statistically significant (p less than 0.05). Adverse reactions were common but tolerable. The reported side effects were headache in 32, skin rash in 18, dizziness in 10, palpitation and itching in 9 each, nausea in 7, flushing in 3, and vomiting in 1 patient. In conclusion, the present study demonstrates that individual dose titration with nitroglycerin patches for obtaining significant antianginal effect is essential. The present therapeutic system is convenient to use and well tolerated and had acceptable side effects in our study population.

Recombinant human interleukin-2 (rIL-2) was administered to 34 patients with advanced malignancy. Three schedules of rIL-2 administration employed were as follows: (A) 2-hr iv infusion of 6.7 X 10(5) U/m2/day (A1, 6 cases) or 2.2 X 10(6) U/m2/day (A2, 8 cases) for five consecutive days; (B) 24-hr continuous iv infusion of 3.3 X 10(5) U/m2/day (B1, 3 cases), 6.7 X 10(5) U/m2/day (B2, 7 cases) or 1.1 X 10(6) U/m2/day (B3, 5 cases) for 28 consecutive days; and (C) 24-hr continuous iv infusion of 6.7 X 10(5) U/m2/day (C, 5 cases) for 5 consecutive days per week for four weeks. The common side effects were fever (79%), eosinophilia (61%), malaise (56%), erythema or rash (50%), chills (38%) and nausea or vomiting (35%), with the dose-limiting toxicities being hypotension in group A, and renal dysfunction with fluid retention in groups B and C. In the case of 2-hr iv infusion, rIL-2 was rapidly cleared from the plasma, with a half life of about 30 min, while in the case of 24-hr continuous infusion, more than 1 U/ml serum IL-2 activity was maintained for 14 days in group B3. Natural killer (NK) and lymphokine-activated killer (LAK) activities were augmented by rIL-2 administration in patients of groups A, B3 and C. In eight patients of group B, NK and LAK activities transiently decreased after rIL-2 administration, and recovered by day 3. The percentage of IL-2 receptor and Leu HLA-DR positive cells reached the peak level on day 7 in group B. In patients of group C, the percentage of Leu HLA-DR positive cells as well as NK and LAK activities increased upon rIL-2 administration and decreased during an intermission of two days. However, the percentage of rIL-2 receptor positive cells increased during the intermission of rIL-2. The most effective schedule of rIL-2 administration was considered to be the schedule of group C on the basis of this study.

The clinical symptoms and signs were assessed in 20 consecutive patients developing infection with the human immunodeficiency virus (HIV). All were male homosexuals and all presented with a glandular-fever-like illness. Changes in laboratory values were compared with findings in 40 HIV negative male homosexual controls. In the 10 patients for whom date of exposure to the virus could be established the incubation period was 11-28 days (median 14). One or two days after the sudden onset of fever patients developed sore throat, lymphadenopathy, rash, lethargy, coated tongue, tonsillar hypertrophy, dry cough, headache, myalgia, conjunctivitis, vomiting, night sweats, nausea, diarrhoea, and palatal enanthema. Twelve patients had painful, shallow ulcers in the mouth or on the genitals or anus or as manifested by oesophageal symptoms; these ulcers may have been the site of entry of the virus. During the first week after the onset of symptoms mild leucopenia, thrombocytopenia, and increased numbers of banded neutrophils were detected (p less than 0.0005). The mean duration of acute illness was 12.7 days (range 5-44). All patients remained healthy during a mean follow up period of 2.5 years. Heightened awareness of the typical clinical picture in patients developing primary HIV infection will alert the physician at an early stage and so aid prompt diagnosis and help contain the epidemic spread of AIDS.

Idarubicin (4-demethoxydaunorubicin: DMDNR) is an orally active analogue of daunorubicin that has shown promising activity in animal and early clinical studies. We gave idarubicin in a phase II study to patients with advanced breast cancer unresponsive to hormonal manipulation and in some cases to standard chemotherapeutic agents. Idarubicin was given orally every 21 days at a starting dose of 40 mg/m2 with dose escalation until myelosuppression occurred. Nadir blood counts showed that patient compliance was good. Of 33 patients studied, 32 are evaluable for response: 4 (13%) had partial responses (95% confidence interval 1%-23%) with a duration of response between 32 and 59 weeks; 8 (25%) had static disease for between 17 and 48 weeks; and 20 failed to respond. For patients not previously exposed to chemotherapy, the response rate was 3/19 (16%). Toxicity was mild, with little or no gastro-intestinal disturbance in the majority of patients, no severe haematological toxicity and little alopecia. Two patients however, were withdrawn from the study because of toxicity; one with a skin rash and one with severe vomiting. Idarubicin produces little toxicity when given orally at a dose of 40 mg/m2 every 21 days, but its activity in breast cancer is insufficient to justify its further use with this schedule. Further studies should be undertaken only if direct comparison can be made with doxorubicin.

Sixteen patients with previously treated acute nonlymphocytic leukemia or chronic myelogenous leukemia in blast crisis were given one to three courses of esorubicin by continuous infusion over 48 h. Dosage levels extended from 35 to 85 mg/m2. Four patients showed partial responses of short duration. Nonhematological toxicity observed at dosages of 55 to 85 mg/m2 were mucositis, diarrhea, skin rash, transaminitis, nausea, vomiting, and cardiac dysfunction. One patient receiving 85 mg/m2 developed acute florid congestive heart failure within hours of administration of the drug. Pharmacokinetic analysis revealed large interpatient variation in plasma drug levels. At the end of infusion, plasma decay of esorubicin was rapid initially but slow thereafter, with a terminal half-life of 20 to 54 h. The metabolite 4'-deoxy-13-hydroxydoxorubicin reached significant plasma levels. Total body clearance, renal clearance, volume of distribution at steady state, and mean residence time show little variation during dose escalation for both esorubicin and 4'-deoxy-13-hydroxydoxorubicin. Urinary excretion of esorubicin and 4'-deoxy-13-hydroxydoxorubicin accounted for 10.5 and 1.5%, respectively, of the administered dose.

Iproplatin was administered intravenously over 30 min daily for 5 consecutive days every 3 weeks to 80 evaluable patients with a variety of refractory solid tumor malignancies. Thrombocytopenia was the dose-limiting toxicity. Reversible drug-induced renal dysfunction was observed in 3 patients. One patient sustained mild ototoxicity but neurotoxicity was not encountered. Transient neutropenia, anemia, nausea, vomiting, diarrhea, elevations of liver enzymes, alopecia, and skin rash also occurred. The spectrum and severity of toxicity of iproplatin were found to differ from those of cisplatin. The maximally tolerated dose (MTD) was 45 mg/m2/day in patients who received prior chemotherapy and 65 mg/m2/day in those who did not. No complete responses occurred. Partial responses were obtained in 2/15 patients with colon cancer, 3/18 with breast cancer, 2/4 with carcinoma of unknown primary site and 1/2 with pancreatic cancer. Thirteen patients with lung (5), breast (4), colon (2), head and neck (1) and cervical (1) cancers had stable disease. Based on the different toxicity profiles between iproplatin and cisplatin and the possible antitumor efficacy of the former, phase II investigation of iproplatin has been initiated.

A total of 45 courses of 50 g (24 to 33 g/m2) of high-dose methotrexate (HDMTX) followed by an improved citrovorum rescue (CFR) were administered to 23 patients according to a recently updated procedure. All patients previously had received HDMTX-CFR at lower doses. The HDMTX was administered intravenously (IV) over 6 hours with a priming dose of 8 g followed by 42 g given by continuous infusion. Maintenance of adequate urine output and pH level were achieved with IV fluids, sodium bicarbonate, oral acetazolamite, and a low-acid diet. The CFR was administered by following the equimolar rescue technique and was continued until the serum MTX level was less than 2 X 10(-7) mol/l. The MTX was usually rapidly cleared. The median 48-hour serum MTX level was 7.57 X 10(-6) mol/l (range, 6.8 X 10(-7) mol/l to 7.9 X 10(-5) mol/l). Most patients cleared MTX to below 10(-7) mol/l by the eighth day (range, 5 to 13 days) after MTX infusion. The MTX clearance did not always correlate with the pretreatment creatinine clearance. The toxicity observed included the following: leukocyte count less than or equal to 2000/microliters in 11% of the courses with less than or equal to 1000/microliters in 0%, platelets less than or equal to 10(5)/microliters in 9%, creatinine elevation to greater than or equal to 1.5 mg/dl in 7%, mild mucositis without ulcerations in 33%, nausea with occasional vomiting in 66%, mild skin rash in 18%, and temporary elevation of liver enzymes in 81% of the courses. All side effects were tolerable and transient, and the patients recovered fully. Patients who cleared MTX rapidly (MTX less than or equal to 2 X 10(-6) mol/l at 48 hours) rarely sustained leukopenia, creatinine elevation, or skin rash. Toxicity was not increased by third space fluids or by delaying CFR to 24 hours instead of 12 hours after MTX. The procedure described allows the safe administration of HDMTX-CFR at the 50-g range to adults with advanced malignant solid tumors.

Sixteen patients with metastatic melanoma or metastatic renal cell carcinoma were treated with six weekly 24-hour infusions of recombinant interleukin-2. At least three patients were treated at each dose, beginning at 3.0 mU/m2 for 24 hours each week for 6 weeks. Subsequent patients were treated at 4.5, 6.0, 8.0, and 10.0 mU/m2 for 24 hours. The incidence of diarrhea, rigors, rash, edema, and symptomatic hypotension was positively correlated with dose level. Symptomatic hypotension was dose limiting at the 10-mU/m2 level. Fever, nausea, and vomiting were seen at each dose level and could not be correlated with dose level. Lymphopenia and eosinophilia were observed at the completion of each 24-hour infusion, and an increase in peripheral blood absolute lymphocytes and eosinophils was observed over the 6-week treatment period. No thrombocytopenia was observed. No change in delayed-type hypersensitivity (type IV) as determined by skin testing could be demonstrated at any dose level. Natural killer cell cytotoxicity of peripheral blood lymphocytes increased over the treatment period, but the increase was unrelated to dose level in the range studied. One minor response was documented in a patient with renal cell carcinoma.

From 1977 to 1982, 62 patients with various advanced malignant solid tumors were treated by HD-MTX-CFR therapy and totally 129 courses were given. Majority of the patients suffered from malignant lymphoma (10), osteogenic sarcoma (11), lung cancer (16), esophageal cancer (3), breast cancer (3) and malignant melanoma (4). All were confirmed by cytology or pathology except one primary liver cancer. There were clinically measurable lesions in 59 patients for evaluation of the treatment, and 3 osteogenic sarcoma patients without metastasis were given a postoperative adjuvant chemotherapy. 33 out of 62 had received chemotherapy and/or radiotherapy before. Dose of MTX ranged from 2 to 3 gm per course in most patients and dose of CF, from 9 to 12 mg every 6 hours for 3 days. 2 (3.4%) patients achieved complete remission (1 osteogenic sarcoma and 1 malignant lymphoma) and 8 (13.6%), partial remission (1 osteogenic sarcoma, 5 malignant lymphoma, 1 esophageal cancer and 1 breast cancer) with a total response rate of 15.9%. No response was observed in all 16 lung cancers. The main side effects of HD-MTX-CFR therapy were leukopenia, thrombocytopenia, elevation of SGPT, nausea, vomiting, mucositis, skin rash, fever and fatigue. All patients were followed more than 3 years. 4 patients are still alive (9, 9, 4 and 7 years, respectively), including 3 osteogenic sarcoma patients who received postoperative adjuvant chemotherapy and 1 mycosis fungoides.

Munchausen syndrome by proxy (MSBP) is a form of child abuse wherein the mother falsifies illness in her child through simulation and/or production of illness, and presents the child for medical care, disclaiming knowledge as to etiology of the problem. From the literature, 117 cases of MSBP were reviewed. The most common presentations of MSBP were bleeding, seizures, central nervous system depression, apnea, diarrhea, vomiting, fever, and rash. Short-term morbidity rate was 100%; long-term morbidity rate was 8%. Mortality rate was 9%. Failure to thrive was associated with MSBP in 14% of cases. All perpetrators of MSBP were the mothers. The origins of this type of aberrant maternal behavior remain abstruse, as do the long-term psychological effects on the child victims. Guidelines for medical, social service, and legal management are provided.
