The efficacy and tolerance of proquazone, 900 mg, and ibuprofen, 1200 mg, were compared in a randomized, double-blind clinical trial of 6 months' duration, with 44 patients, 21 on proquazone and 23 on ibuprofen. Comparison of proquazone-treated patients with patients treated with iburofen showed a significantly better improvement , as is demonstrated by the significant differences in the Lansbury Index, in nocturnal pain, final assessment of therapeutic effect, and number of interruptions due to lack of efficacy. All differences were in favour of proquazone, proving its therapeutic superiority over ibuprofen. The side effects in the proquazone group were mainly gastrointestinal, and 2 patients broke off treatment prematurely due to diarrhoea (in one patient, lack of efficacy was a contributory cause). A third patient discontinued because of moderate nausea and dizziness. In the ibuprofen group, 4 patients discontinued because of side effects (skin eruptions, dizziness, epigastric discomfort, and one thrombocytopenia) in addition to lack of efficacy. Proquazone seems to be an effective and well tolerated anti-inflammatory analgesic.

Ftorafur, a furanyl analog of 5-fluorouracil (5-FU), is reported to be five to six times less toxic and possibly more effective in cancer of the breast and colon than 5-FU. The drug was synthesized, formulated, and utilized in toxicologic studies, and then in 24 patients with advanced incurable malignancies. When Ftorafur is given by intravenous push, it results in immediate flushing, dizziness, nausea, retching, and in some cases transient hypotension. These immediate side effects are largely eliminated by administering the drug slowly by infusion. In patients, 60 mg/kg of Ftorafur given i.v. daily for up to 10 days resulted in mild toxicity. However, 80 mg/kg given i.v. daily for 7 days resulted in severe toxicity, with nausea, vomiting, stomatitis, leukopenia, and thrombocytopenia. These studies confirm those of the Russian investigators as to toxicity and dosage, even with a different method of administration more convenient for therapy. Phase II studies are presently being carried out to compare the effectiveness of Ftorafur and 5-FU.

Biological response modifiers (BRMs) have greatly modified the immunotherapy of tumors. Interleukin-2 (IL-2) has brought about metastasis regression in some cases of malignant tumors, however, when given systemically, it results in high toxicity. More recently, the subcutaneous administration of IL-2 (combined with alpha-interferon, alpha-IFN) seems to be capable of offering the same chances of therapeutic response, but this time with a lower level of toxicity. The Authors report an evaluation of toxicity in 22 patients treated with a combination of IL-2 + alpha-IFN i.m. with or without chemotherapy. The side-effects present in the majority of cases were: fever, diarrhea and asthenia. Approximately 50% of the patients had nausea/vomiting, mucositis, skin rashes, and slight leukopenia. The following side-effects were noted to a much lesser degree, thrombocytopenia, alterations in hepatic and dizziness and cystitis. Only one patient reached 4th degree toxicity, with mucositis, asthenia and skin rash. All the other patients received the treatment without suspensions for toxicity. Biological evaluations will enable us to determine in the future, the cases which can benefit from therapeutic intensification and thus it would seem opportune at this time to use therapy with acceptable toxicity.

Diuretics can result in various undesired biochemical changes, such as impotence, skin rashes, nausea, dizziness and lethargy as well as subjective side effects. The side effects are mostly predictable, their effects depending on both the circulatory blood volume and on the transport of water and solute in the renal tubules. Two of the commonest side effects are mild hypovolaemia, when any diuretic is used, and mild hypokalaemia when the non-potassium-sparing diuretics, such as thiazides and frusemide are used. Its occurrence is dose dependent and can be corrected by potassium supplements, but potassium-retaining diuretics, which also correct the often associated fall in serum magnesium, are preferable. Many reports link hypokalaemia with cardiac arrhythmias, but some dispute this association in the absence of the concomitant use of digoxin. Hyponatraemia rarely occurs, but can be life threatening. Calcium excretion is markedly reduced, but unlike other electrolyte disturbances from diuretics, this may be valuable: some suggest diuretics have an anti-osteoporotic action. Diuretics increase glucose and insulin resistance and should be used sparingly in diabetics. They rarely cause a non-ketotic hyperosmolar coma. Urate is raised, but clinical gout is not common. Cholesterol elevation has been reported in some studies, but long-term studies indicate that lipid changes are minor. Other rare side effects are not predictable from their pharmacological actions and these include the occurrence of skin rashes, thrombocytopenia, pancreatitis and interstitial nephritis; and ototoxicity from frusemide.

The occurrence of hypoplastic acute leukemia is widely recognized as an atypical leukemia, and is defined as hypocellular marrow with more than 30% blasts and none or few blasts in the circulating blood. The pathogenesis of hypoplastic acute leukemia is still unknown. Clinically, it usually follows a less progressive course and has a high prevalence rate among the elderly. The treatment and prognosis remains unclear. We present a case of hypoplastic acute leukemia, which responded well to low dose Ara-C. The 67 year-old female patient had symptoms of bruising easily and dizziness for about 3 years. Initial investigation revealed pancytopenia in the circulating blood and hypocellularity (10%) with blast cells (60%) in the bone marrow. Besides supportive treatment with blood transfusions and antibiotics, chemotherapy of low dose Ara-C 10 mg/m2 was administrated for 14 days by subcutaneous injection. Bone marrow examination revealed an increase of cellularity and a decrease of blast cells following chemotherapy. Anemia and thrombocytopenia also simultaneously improved. Such results may suggest induction of differentiation effect of low dose Ara-C in hypoplastic leukemia.

Clinical and epidemiological features of 72 cases of boutonneuse fever, detected from 1979 to 1986 at the "Hospital del Insalud de Cartagena" (Murcia), are reviewed. The most important clinical features are commented on (fever, rash, tache noire), as well as the less important (dizziness, cough, conjunctivitis, sensorial changes). Several epidemiological factors were analyzed, temperature having been found to be the most significant in our area. The complications observed mainly affected patients with risk factors (senility, thrombocytopenia, hyponatremia, high blood pressure) being particularly severe in a patient who developed lethal DIC and in another 2 who developed pulmonary thromboembolism. The prophylactic measures suggested were the strict control of animals susceptible to parasites and organizing of disinfestation campaigns in the endemic areas.

The acquired immunodeficiency syndrome (AIDS) was first diagnosed in burundi in 1983 when a large number of patients were registered with Kaposi's sarcoma, cryptococcal meningitis, and disseminated candidiasis. In the 1st phase of the disease the vi rus is dormant. In the 2nd phase seroconversion appears; and in the 3rd phase generalized adenopathy emerges. In the 4th phase the full-blown disease appears as a result of cellular immunity deficit with emaciation, fever, sweating, chronic diarrhea, asthenia, blood parameter changes (lymphopenia, thrombocytopenia, leukopenia, anemia, and specific immune disorders). The early phases can be diagnosed by serological tests. During 1989 a group of 155 patients with 1st signs of seropositivity were studied in the central hospital of Bugumbura. The available clinical diagnostic markers were: 56 cases of herpes, 26 cases of generalized adenopathy, 25 cases of inflammatory infiltration of paraganglionic zones, 13 abscesses and phlegmons, 8 cases of chronic proctitis, 8 prurigo cases, 7 cases of chronic pneumonia and bronchitis, 4 cases of paresis of the facial nerve, 4 cases of Kaposi's sarcoma, 2 cases of fresh syphilis, 2 cases of anemia, asthenia, dizziness, and weight loss. Tomo- and zonographical X-ray study of the thorax of 80 patients aged 20-65 (51 men and 29 women) was performed. In 62 patients changes in the lungs were evident. In 2 patients tuberculosis of the lungs was diagnosed: miliary TB in a 26-year woman and disseminated TB in a 31-year man. 2 chronic and 3 bronchial, and 10 interstitial pneumonia cases were diagnosed in 15 patients with average age of 30 years. 4 patients had peribronchial and pneumonic infiltrations. In a group of 45 patients magnified picture showed no deformation in the lungs; and only 5 had respiratory organ pathology. Interstitial pneumonia was the most often diagnosed ailment by X-ray inpatients infected with HIV.

To determine the tolerance and safety of moricizine, the incidence and nature of its noncardiac adverse effects and organ toxicity reported during short- and long-term clinical studies were examined. From a pooled data base of 1,256 adult patients and healthy subjects, the most frequent non-cardiac adverse events were gastrointestinal (nausea) and neurologic (dizziness) complaints which occurred in 10 to 15% of patients during short-term (less than 3 months) studies and increased to 20 to 25% during long-term (greater than 12 months) studies. Adverse effects led to discontinuation of moricizine therapy in 116 patients (9%). Organ toxicity consisted predominantly of drug fever, possible thrombocytopenia and elevated liver function tests and was quite low (less than 0.7%) for both short- and long-term studies. Moricizine appears to be a well-tolerated antiarrhythmic drug with low occurrence of noncardiac adverse effects without significant serious organ toxicity.

A case of hybrid phenotypic chronic myelomonocytic leukemia (CMMoL) transformed from a hematological remission state of severe aplastic anemia is reported. A 63-year-old woman was admitted to our hospital with complaints of easy fatigability and dizziness in December 1978. A diagnosis of aplastic anemia was made from findings of pancytopenia and hypoplastic marrow without dysplasia, and she was treated successfully with mepitiostane. Seven years later, anemia and thrombocytopenia reappeared with monocytosis. On the second admission, the peripheral blood showed a white blood cells count of 3.5 X 10(3)/microliters with 54% monocytes. The bone marrow was hypercellular with monocytosis, and dysplasia of three cell lineages was noted. A diagnosis of CMMoL was made. Cytogenetic analysis of bone marrow cells revealed a karyotype of 45 XX, -7, 11q-, and surface markers were polyphenotypic, including CD20+, CD14+ and CD13+. This is the first report of CMMoL with biphenotype which was transformed from aplastic anemia.

Otolaryngological manifestations of 90 patients (of which 50 were under 16 years) with immune thrombocytopenia purpura (I.T.P.) appearing at the Pingdingshan Hematological Institute over 10 years have been studied. Among the sick children, epistaxis was the most common complaint (of which 60% responded to nasal packing), followed by gum, buccal, conjunctive, tongue, lips, eyelids, facial and throat bleeding, in this order. Severity and recurrence were correlated with the sick children's condition: the presence or absence of local trauma and infection, blood platelet level and capillary fragility, especially in acute I.T.P. Some therapeutic principles for these associated abnormalities are recommended. Other conditions included: hearing loss, vertigo, or dizziness, tinnitus, facial paralysis and so on. Our conclusion is that the role of immune responses may be important in the etiopathogenesis of these non-hemorrhagic abnormalities, and should not be ignored in treating the problems as result of I.T.P. In this paper, these immunological and pathological mechanisms implicated in the two problems described above are also discussed.
