In the US and northern Europe, the prevalence of pregnant syphilitic women is estimated at .1-.6%, while in South Africa it was 7.6% in 1982. In 1978, there 108 cases in the US which increased to 268 reported cases in 1985. The increase of congenital syphilis (CS) by 25% from 1985 to 1988 was attributed to the spread of crack cocaine in the US. The rate was 10.5 cases/100,000 live births in the US during this period, a 21% increase. In contrast, in the Netherlands there were 2.5 cases/100,000 live births during 1982-85. Clinical symptoms appear 3 weeks after birth, but some are present at birth such as hepatosplenomegaly, bloated abdomen, cutaneous lesions, and nasal discharge turning into purulent rhinitis. Anemia occurs in 90% of children with CS. Generalized lymphadenopathy, splenomegaly with hepatomegaly, and syphilitic hepatitis may also occur. Syphilitic skeletal abnormalities include osteochondritis, periostitis, osteomyelitis, and osteitis. Meningovascular syphilis produces nervous system effects. CS complications include nephrotic syndrome and acute glomerulonephritis. Ocular abnormalities are caused by treponemes found in the cornea, sclera, uvea, retina and the optic nerve. Chorioretinitis and iridocyclitis are common ocular lesions. The pathogen Treponema pallidum can be diagnosed by dark field microscopy, by immunofluorescence, or by histopathological examination of silver-stained preparations. Pregnancy women with syphilis are treated with penicillin although failures have been reported after single or 2 or 3 in administrations of 2.4 MU benzathine penicillin and after giving tetracycline in 3rd trimester pregnancy. The CDC recommendation for treating infants with CS is iv 50,000 U/kg penicillin G every 8-12 hours for 10-14 days or im 50,000 U procaine penicillin once daily for 10-14 days. Single administration of 50,000 U/kg benzathine penicillin is recommended for newborn children whose mothers have been treated with erythromycin.

We enrolled 253 HIV-antibody positive heroin addicts without HIV-related disease (n = 81) or with persistent generalized lymphadenopathy (n = 172) in a prospective study to evaluate clinical progression to AIDS related complex (ARC) or AIDS and to identify factors of possible prognostic relevance. Follow-up lasted between 6 and 40 months (median 12 months). According to the non-parametric Cox's model the only significant (P less than 0.001) prognostic variable was T4+ cell count considered in three classes: greater than 800/microliters (no depletion), 400-800/microliters (moderate depletion) and less than 400/microliters (absolute depletion). Subjects with T4+ cell count of less than 400/microliters had a risk of developing ARC or AIDS that was 6.46 and 1.98 higher than those with values of greater than 800/microliters or between 400 and 800/microliters respectively. The estimated probability of progression to ARC or AIDS was 0.029, 0.056 and 0.172 at one year in subjects with T4+ cell count of greater than 800/microliters 400-800/microliters and less than 400/microliters, respectively, and 0.296, 0.501, and 0.896 at two years.

Levels of erythropoietin and granulocyte-macrophage colony-stimulating factor (GM-CSF) were measured in sera of 28 HIV-seronegative heterosexual non-intravenous drug using controls, 57 HIV-seronegative and 42 HIV-seropositive asymptomatic intravenous drug users (IVDU) and 36 HIV-seronegative and 36 HIV-seropositive homosexuals, 79 patients with lymphadenopathy, 11 patients with AIDS-related complex (ARC) and 110 patients with AIDS. Serum erythropoietin levels were significantly elevated in HIV-seronegative and HIV-seropositive asymptomatic homosexuals and in patients with lymphadenopathy, ARC and AIDS when compared to controls. However, in asymptomatic HIV-seronegative and HIV-seropositive IVDU the erythropoietin levels were not significantly different from the control group. GM-CSF mean levels in both HIV-seronegative and HIV-seropositive IVDU were elevated compared with the level in controls, whereas the mean levels in both the HIV-seronegative and HIV-seropositive homosexuals were decreased relative to the level in controls. GM-CSF levels in patients with lymphadenopathy, ARC and AIDS were not significantly different from the control value. It appears that male homosexuals have mildly increased erythropoietin levels which rise substantially with the development of ARC and AIDS, which suggests that AIDS patients have intact capacity to produce erythropoietin. In contrast, GM-CSF levels are increased in association with IVDU but are not increased in association with HIV infection including ARC or AIDS. The difference in circulating levels of erythropoietin and GM-CSF may reflect the tissue sources of erythropoietin predominantly in the kidney and GM-CSF being a product of the immunological and inflammatory systems.

Anorectal lesions are uncommon in patients infected by the HIV virus (13%, 1 female and 15 males in our personal series). Certain neoplastic lesions are specific and must suggest the possibility of AIDS: Kaposi sarcoma, non-Hodgkin's malignant lymphoma and, in young subjects, intra-epithelial dysplasias, carcinomas in situ or squamous cell of the anus. Other lesions encountered in proctology should also raise the suspicion of HIV infection: anorectal lesions of STD including florid papillomatosis, most frequently (25%) in its severe and recurrent form, extensive herpetic lesions refractory to the usual treatments, Cytomegalovirus ulcers. The clinical history, specifying sexual habits, a history of drug abuse and looking for the presence of chronic diarrhoea, and a complete clinical examination looking for lymphadenopathy are important elements to be considered in favour of the diagnosis. Apart from painful emergencies requiring an immediate surgical procedure, the therapeutic of the patient's general state, the stage of the disease and the expected benefit for the patient's comfort.

Plasma samples from patients with chancroid diagnosed both on clinical and microbiological grounds were assessed for their ability to inhibit mitogen-induced proliferation of human lymphocytes from healthy donors. All serum samples analysed suppressed phytohaemagglutinin A (PHA) blastogenic response. A significant difference in the observed extent was seen when serum samples from patients with and without associated lymphadenopathy were compared (P < 0.05). Using an interleukin-2 (IL-2)-dependent cell line it could be demonstrated that the addition of patients' plasma to cultured cells markedly depressed mitogen-induced IL-2 synthesis. Results presented suggest that cell-mediated mechanisms play a role in the pathogenesis of infection due to Haemophilus ducreyi.

Clinicians monitored 15 full-term infants born to 12 HIV-1 seropositive commercial sex workers in the Philippines for signs and symptoms of HIV-1 infection. They performed a physical examination and HIV test on each infant every 3 months. The mean follow-up period was 39.3 months (range 7-72 months). Two infants tested positive for HIV-1 infection. When the researchers excluded the four infants under 18 months of age, the HIV-1 perinatal transmission rate stood at 18.2%. The maternal antibodies in seven infants who were monitored for at least 25 months disappeared; yet six subsequently developed indeterminant Western blots (i.e., reactivity to p24 and/or gp120/160, but no reactivity to gp41). The maternal antibodies in two of the six remaining infants who were under 25 months old disappeared within 1 year. The Western blots still recognized either p24 or gp120/160 in the other four infants beyond the accepted 15-month period for loss of maternal antibody. The clinicians could not establish a diagnosis based on these laboratory findings. They did diagnose signs and symptoms that may indicate HIV-1 infection (i.e., failure to thrive, anergy, persistent generalized lymphadenopathy, and recurrent pneumonias). Yet these clinical features are prevalent in many infants in developing countries, thereby making their usefulness in diagnosing perinatal HIV-1 infection limited.

We report the results of a recent trial in elderly acute lymphoblastic leukemia (ALL) patients (> or = 60 years). Initial chemotherapy consisted of one 14-day course with single-dose idarubicin plus vincristine-prednisone-L-asparaginase. Idarubicin was preferred to other anthracyclines because of its shorter time to response. Sequential outpatient postremission therapy included single-dose idarubicin plus vincristine-cyclophosphamide-L-asparaginase pulses, cranial irradiation with intrathecal methotrexate-cytarabine, flexible weekly vincristine-cyclophosphamide alternating with cytarabine-teniposide, and two-year standard maintenance with mercaptopurine-methotrexate. Granulocyte colony-stimulating factor (G-CSF) was added to induction and early consolidation courses. Twenty-two patients mainly with high-risk features entered the study: median age was 64 years (60-73), 40% of cases were CD10- B-lineage and T-lineage ALL, 38% of CD10+ B-lineage ALL carried a BCR-ABL rearrangement, while 23% coexpressed myeloid antigen, 86% had L2 morphology, 50% had a blast count greater than 10 x 10(9)/1, 54% had hepato-splenomegaly and lymphadenopathy. The complete remission (CR) rate after induction therapy was 59%. A partial remission was obtained in two cases. There were four early deaths (18%) and three refractory ALL (14%). Median time to response was 21 days. With G-CSF, the median duration of absolute neutropenia was 10.5 days. Flexible postremission therapy was very well tolerated, causing no major toxicity. With a median follow-up of 2.6 years, 3 patients remain alive in first CR (23%), 2 of whom at 21.3 months and 39.6 months, respectively. Median survival of responders was 12 months compared to only 1.2 months for nonresponders (p < 0.001). This moderate-dose idarubicin-containing and G-CSF-supported regimen was associated with a high early remission rate in elderly ALL. Postremission therapy results were modest, though not appreciably different from the general experience in this patient population. Because further escalation of drug intensity appears unjustified, attempts to document and reverse drug resistance patterns and restore a dysregulated apoptosis must be considered.

A cross-sectional study of a cohort of 49 male human immunodeficiency virus (HIV)-infected intravenous drug users attending the Infectious Diseases Unit of the National University of Malaysia during 1991-94 yielded a clinical profile of these patients. The mean age of respondents was 33.2 years and the mean duration of intravenous drug use was 12.7 years. On average, these men had known of their HIV-positivity for 53.2 weeks. Intravenous drug use was the only reported HIV risk factor in 34 men (69%). Clinical symptoms at intake included fatigue (49%), weight loss (47%), night sweats (31%), fever (14%), and diarrhea (6%), while clinical findings included hepatomegaly (57%), lymphadenopathy (35%), and oral thrush (29%). Anemia (82%), leucocytosis (53%), hypoalbuminemia (43%), hyperglobulinemia (88%), elevated liver enzymes and hyponatremia (57%) were frequent laboratory findings. The prevalences of hepatitis B virus, cytomegalovirus, and toxoplasma infection were 12.1%, 72.7%, and 59%, respectively. A total of 91 diagnoses were made in these 49 patients: most common were pneumonia, tuberculosis, bacteremia, infective endocardiditis, mycotic aneurysm, and psychiatric disorders. The mean duration of known progression to acquired immunodeficiency syndrome (AIDS) in the 7 patients at this stage was 391 days. Pneumocystis carinii pneumonia was the most common AIDS-defining illness. Three months into the study, 19 men (57%) had defaulted, reflecting the difficulties of involving drug addicts in research and intervention projects. Moreover, 16 patients (33%) were first confirmed HIV-positive at presentation to the hospital, suggesting that many drug users' HIV status remains unknown until they develop symptoms requiring hospital care.

SHIP is an inositol 5' phosphatase that hydrolyzes the PI3'K product PI(3,4,5)P3. We show that SHIP-deficient mice exhibit dramatic chronic hyperplasia of myeloid cells resulting in splenomegaly, lymphadenopathy, and myeloid infiltration of vital organs. Neutrophils and bone marrow-derived mast cells from SHIP-/- mice are less susceptible to programmed cell death induced by various apoptotic stimuli or by growth factor withdrawal. Engagement of IL3-R and GM-CSF-R in these cells leads to increased and prolonged PI3'K-dependent PI(3,4,5)P3 accumulation and PKB activation. These data indicate that SHIP is a negative regulator of growth factor-mediated PKB activation and myeloid cell survival.

A 32-year-old male with a 4-year history of chronic myelogenous leukemia (CML) in chronic phase for 4 years, then myeloid blast crisis for 7 months, developed diffuse bulky lymphadenopathy in association with a white blood count (WBC) of 17,100/mm3 with 70% blasts. Biopsy of a cervical lymph node revealed a blastic extramedullary myeloid cell tumor, which showed a biphenotypic (mixed myeloid/T-cell) immunophenotype. Chromosomal analysis revealed karyotypic features of both myeloid and lymphoid lineages. Although extramedullary myeloid cell tumor (EMT, granulocytic sarcoma, chloroma) is well known to occur in chronic myelogenous leukemia (CML), to our knowledge this is the first description of evolution of CML into a biphenotypic EMT.
