Hyperviscosity syndrome was associated with increased plasma content of monoclonal immunoglobulin (IgA or IgM) in 3 dogs with lymphocytic leukemia. The diagnosis of lymphocytic leukemia was based on the finding of a large number of mature lymphocytes in the blood and bone marrow. The clinical signs included weakness, lethargy, depression, and coughing due to congestive heart failure. Consistent physical findings were splenomegaly, with or without peripheral lymphadenopathy, and funduscopic abnormalities. Of the 2 dogs treated successfully with chlorambucil, 1 remains in remission after withdrawal of the drug for over 1 year.

Twenty-one patients with brucellosis wereinvestigated. Four patients with the classical manifestations of acute brucellosis presented no problems in diagnosis. The other 17 patients suffered from chronic disease and had no history of any acute episode of brucellosis. The most common symptoms in this group were tiredness, fatigue, depression, arthralgia and muscular pains. Abdominal pain and pain in the temperomandibular joints were marked in some patients. Most of these patients had been receiving psychiatric treatment. Clinical examination was largely negative, but lymphadenopathy was found in 9 cases. Brucella meningo-encephalitis was diagnosed in 7 patients who complained of severe headache. Problems in the diagnosis of chronic brucellosis with an insidious onset are discussed.

We report a Japanese boy with centrifugal lipodystrophy. The initial lesion developed on the forehead as an area of erythema which showed centrifugal spread and central fading to leave a residual depression. Three years later, similar erythematous lesions appeared on the cheeks, and he developed a cadaverous appearance. A central depression on the upper trunk was surrounded by an erythematous border and there was right cervical lymphadenopathy. Histological examination revealed inflammatory changes in the subcutaneous fat. Although this patient showed the characteristics of both centrifugal and progressive lipodystrophy (partial lipodystrophy), we consider that he has centrifugal lipodystrophy of the face because of the overall features of the lesions.

This study correlates the prevalent oral disease findings in 390 patients seropositive for human immunodeficiency virus type 1 (HIV-1) with their level of staging (Walter Reed) and depletion of peripheral helper T lymphocytes (CD4+). Chronic lymphadenopathy of the head and neck was a common finding (59.2%) that occurred early in staging progression and did not correlate with depression of helper T-cell levels. Of the three prevalent oral disease findings (oral hairy leukoplakia (OHL), candidiasis, necrotizing ulcerative gingivitis [NUG]) only OHL and NUG were significantly correlated with helper T-cell depletion. The occurrence of visually detectable OHL and NUG corresponds to depletion of peripheral helper T-lymphocyte values in a range of 157 to 299 cells/mm3. This range may represent a more accurate value for biologically significant lymphocyte depletion than the Walter Reed value of 400 cells/mm3. The presence of OHL showed a weak statistical correlation with staging progression, indicating deteriorating immunoregulation. No cases of Kaposi's sarcoma or other HIV-1-associated oral diseases were observed in the sample population, regardless of the patient's staging category or peripheral helper T-lymphocyte count.

A 13-month-old Doberman Pinscher was evaluated because of slowly progressive paraparesis and signs of depression. The dog had temporal, supraspinatus, and infraspinatus muscle atrophy, bilateral enophthalmos, superficial inguinal lymphadenopathy, tachycardia with pulse deficits, and lesions of active and inactive chorioretinitis. Neurologic abnormalities included hyperreflexic patellar reflexes, lack of conscious proprioception, signs of superficial pain in the hind limbs, and depressed hopping reflexes in the forelimbs. Cranial nerve abnormalities included decreased sensation in the left nostril and a delayed gag reflex. Results of cerebrospinal fluid analysis were characteristic of nonsuppurative inflammation. A diagnosis of multifocal neurologic disease was made. The dog did not have serum titers for fungal diseases, canine distemper, Ehrlichia canis infection, borreliosis, Rocky Mountain spotted fever, or toxoplasmosis. The dog did not respond to various antimicrobial treatments, and only slightly responded to corticosteroid treatment. The dog died during an anesthetic procedure. The postmortem diagnosis of Trypanosoma cruzi infection (canine Chagas disease) was made on identification of the amastigote form of the organism in sections of brain, spinal cord, and myocardium.

Neuropsychological and psychometric investigations have sometimes attested to and sometimes denied the existence of cognitive perturbations during the early phases of human immunodeficiency virus (HIV) infection (stages II and III of the CDC classification): strictly asymptomatic seropositivity or generalized lymphadenopathy. Therein lies the basis of the debate concerning the neurotropism of the virus and its deleterious effects on the central nervous system (CNS). We hoped to contribute to the resolution of this discussion by recording late evoked auditory potentials, which are composed of two types of components: exogenous responses attesting to the reception of stimuli by specific sensory areas of the CNS, regardless of their informative value for the subject; and endogenous responses that occur later, appearing when the subject is required to distinguish between different stimuli, for example, counting high-pitched sounds randomly distributed among low-pitched ones. The latter responses, which have been most extensively studied for wave P300, are associated with cognitive functions, and alterations of the evoked cognitive potentials have been observed during the course of demential syndromes of various origins. Fifteen individuals were subjected to the protocol for recording long-latency, evoked auditory potentials. These studies were completed by a battery of psychometric tests, two methods for evaluating depression and an assessment of the anxiety level. The results showed a significant lengthening of the latency of wave P300 in the seropositive subjects. This prolongation also affected one of the exogenous components, i.e., wave P2. In addition, their intelligence quotients, regardless of whether the IQ explores the so-called crystallized component or the fluid component of intelligence, were not significantly different from those of the general population.(ABSTRACT TRUNCATED AT 250 WORDS)

For many years tuberculosis has been known to occur with greater frequency among persons with disorders that impair host defenses. In most instances these processes interfere with the immune response to Mycobacterium tuberculosis, whereas, in a few, such as silicosis, the probable abnormality is a nonimmune defect in macrophage function. Infection with the human immunodeficiency virus (HIV) causes progressive and ultimately profound depression of both humoral and cell-mediated immunity and, thus, is an extremely potent risk-factor for tuberculosis. Presumably the major effect of HIV infection that predisposes persons to developing tuberculosis is the reduction in circulating T-helper (CD4+) lymphocytes which causes a reduction in cytokine production and a consequent decrease in the functional capabilities of macrophages. However, a number of questions concerning pathogenesis of tuberculosis related to HIV remain. Available data suggest that the magnitude of the risk for developing tuberculosis among persons infected with both HIV and M. tuberculosis is very high, 8% in one prospective study. Because of the epidemic of HIV infection, the progressive downward trend in the incidence of tuberculosis in the United States has reversed and in 1989 there was a 5% increase in the number of cases. Preliminary data for 1990 suggest that there will be an 8 to 10% increase over 1989. Also in the United States approximately 3% of tuberculosis patients have been found to be HIV seropositive. The clinical features of tuberculosis in patients with HIV infection vary depending on the degree of immunosuppression. With mild immunosuppression early in the course of HIV infection tuberculosis presents in a "typical" way with positive tuberculin skin tests, upper lobe cavitary infiltrates on chest film and positive sputum smears and cultures. As the HIV infection progresses, the mode of presentation of tuberculosis becomes more "atypical" with negative skin tests, multiple sites of involvement, chest films showing diffuse noncavitary infiltrates often accompanied by intrathoracic lymphadenopathy. The key to diagnosis is maintaining a high index of suspicion for tuberculosis, especially in patients with advanced HIV disease and including appropriate laboratory examinations in the evaluations of such persons. Regardless of the stage of HIV infection the response to treatment for tuberculosis is generally favorable if it is begun promptly. Standard therapy utilizing isoniazid, rifampin, and pyrazinamide with or without ethambutol have been associated with high rates of cure. Relapse has been uncommon. There has been, however, at least one outbreak of tuberculosis caused by isoniazid and rifampin resistant organisms in which the response to therapy was very poor.(ABSTRACT TRUNCATED AT 400 WORDS)

Systemic lupus erythematosus (SLE) is poorly described among black children in Africa despite being more frequent among some black adult populations than their white counterparts. The first black South African child with SLE is documented. The patient was a 10-year-old girl who had fever, facial rash (with complement (C4) deposited at the dermo-epidermal junction of normal skin), weight loss, central nervous system involvement (depression, withdrawal, retinal exudates), renal involvement (glomerular filtration rate 54 ml/min/1.73 m2; membranous nephropathy with mild mesangial proliferation; World Health Organisation classification Vb), alopecia, lymphadenopathy, hepatomegaly, positive Coombs test, hypeocomplementaemia, anti-DNA antibodies and positive anti-nuclear factor.

Serum samples from 1421 domestic cats (561 healthy, 860 sick) were tested for FIV-, FeLV- and coronavirus infection. The results were stored in a computer data base and compared with epidemiologic data and clinical findings. All 3 infections were significantly more prevalent in sick than healthy cats: FIV was found in 0.7% of healthy and 3.4% of sick cats. For FeLV the prevalence was 3.0% and 13.0% and for coronavirus 21% and 36.2%, respectively. FIV-infected cats were mostly male (73%); no sex predilection was observed in FeLV- and coronavirus infection. In sick cats FIV-infection was significantly more prevalent in cats greater than 2 years of age; no age-dependence was found in FeLV- and coronavirus infections. The prevalence of FIV-infection increased significantly with the number of animals per household. In contrast, the frequency of FeLV infection decreased with the number of animals per household. Prevalence of coronavirus infection did not vary with group size or living conditions. The following clinical symptoms were associated with infection: FIV: general depression, diseases of the urinary tract; FeLV: general depression, fever, rough hair coat, lymphadenopathy, impaired functions of heart and circulation and muscle atrophy; coronavirus: lymphadenopathy and alterations in the abdomen. It was concluded that based on the clinical symptoms alone FIV-infection could not be diagnosed nor differentiated from the other 2 infections.

Of 467 cat serums tested for antibody to feline immunodeficiency virus (FIV) 120 (26%) were positive. The average age of positive cats was 7.5 years (range 1 to 16 years), and 67% were male. Of 110 serums collected in 1980, 27 (24.5%) were positive. A wide variety of clinical signs including oral cavity disease, anorexia, weight loss, lethargy, depression, fever, respiratory and urinary tract disease, conjunctivitis, abscesses, anaemia and lymphadenopathy were observed in the cats with serum antibody. There was often a history of chronic disease or recurrence of particular or various clinical signs in these cats. FIV was isolated from 4 of 8 FIV antibody positive cats by cocultivation of patient lymphocytes with donor lymphocytes in the presence of interleukin 2.
