[Osteitis in secondary syphilis]. / Osteítis en sífilis secundaria.

BACKGROUND: The aim of this study is to report two patients with osteitis in secondary syphilis. The increase in the number of cases of syphilis, linked to the changes in sexual behavior and to the increase of immigrants from areas of high prevalence of STD, as well as its relationship with HIV infection, makes important to clinicians become aware of unusual presentation of secondary syphilis. PATIENTS: We report two patients diagnosed of secondary syphilis, one of them with HIV infection. Both showed dermatological lesions in palms and soles, malaise and fever. Bone scintigraphy showed significant uptake in parietal and frontal bones in both patients. Clinical response was quickly achieved after penicillin treatment. CONCLUSIONS: In patients with secondary syphilis and osteoarticular symptoms luetic osteitis must be included in differential diagnosis. Bone scintigraphy should be the first diagnostic tool because it possibilities to perform a total body scan which allows localizing asymptomatic lesions. Moreover bone scan shows a high sensitivity.

Osteítis en sífilis secundaria / Osteitis in secondary syphilis

Introducción: El objetivo del presente trabajo es presentar dos casos de osteítis en sífilis secundaria. El aumento de la incidencia de sífilis, debido a los cambios en los comportamientos sexuales y al aumento de los inmigrantes procedentes de áreas con elevada prevalencia de enfermedades de transmisión sexual (ETS), y su relación con el virus de la inmunodeficiencia humana (VIH), hace que sea importante familiarizarse con formas menos frecuentes de presentación de esta infección sistémica. Pacientes: Se presentan dos pacientes diagnosticados de sífilis secundaria, uno de ellos con infección por el VIH y el otro no. En el momento del diagnóstico ambos tenían lesiones cutáneas que afectaban palmas y plantas, síntomas generales y fiebre. La gammagrafía ósea demostró en ambos casos lesiones osteoblásticas múltiples en los huesos parietales y frontal. Los dos enfermos respondieron con mejoría clínica al tratamiento con penicilina. Conclusiones: En los pacientes con sífilis secundaria y sintomatología osteoarticular se debe hacer el diagnóstico diferencial de afectación ósea sifilítica. Recomendamos como técnica de elección la gammagrafía ósea debido a su gran sensibilidad y a la posibilidad de realizar rastreos corporales que permiten el diagnóstico de lesiones sintomáticas. (AU)

Malignancy in systemic lupus erythematosus: a report of five cases in a series of 96 patients.

The association of systemic lupus erythematosus (SLE) and malignancy has been reported previously and suggests an increased risk of cancer in this disease. Lymphomas are the most frequent neoplasias reported in these patients and carcinoma of the cervix and breast are also seen. Several factors probably play a role in the aetiology of malignancies associated with SLE including intrinsic disturbances of immunity and concomitant immunosuppressive therapy. We report five solid tumors (one breast carcinoma, one squamous cell carcinoma of the anus, one adenocarcinoma of the rectum, one carcinoma of the cervix and one carcinoma of the gallbladder) among 96 patients with SLE. The most striking finding in this study was the absence of haematological malignancies. The incidence of malignancy in the series, the age of diagnosis of SLE and neoplasia and the time delay between SLE and malignancy diagnosis was similar to other series. We did not find any clinical or immunological feature that predicted the development of neoplasia. In conclusion, patients with SLE may have the same malignancies as the general population after adjustment for age and sex. There are no predictive indicators for malignancy and immunosuppressive therapy may be a contributing factor.

[A clinical study of Kaposi's sarcoma associated with the acquired immunodeficiency syndrome]. / Estudio clínico del sarcoma de Kaposi asociado al síndrome de inmunodeficiencia adquirida.

We have retrospectively studied 35 cases of Kaposi's sarcoma in 460 patients with AIDS (incidence of 7.6%) during a period of 10 years. All of them were males, with a mean age of 38 years. 88% of the cases belonged to the homosexual risk group. The tumor was the diagnostic criteria of AIDS in 25 patients. At the moment of the diagnosis, 4 patients were at stage I, 23 at stage II, 1 at stage III and 7 at stage IV, according to the Mitsuyasu's classification; 7 patients had systemic symptoms. The tumor was localized at the skin (34 cases), mucosa (16), digestive tract (7), lung (6) and ganglion (4). The immunological study revealed lymphopenia in 74% of patients, reduction of T4 lymphocytes ( < 0.5 x 10(9)/L) in 93% and inverted T4/T8 ratio in 96%. Sixteen patients received antitumoral treatment (8 with chemotherapy, 7 with interferon and 5 with radiotherapy). The response was stabilization of lesions in 8 cases, partial remission in 2 and progression in 3; in other 3 cases, such response was not assessed. The mortality was 48% and the average survival, 13 months. Opportunistic infections were the cause of death in most patients. Our results confirm the clinical and evolutive characteristics of the Kaposi's sarcoma associated to AIDS; disseminated cutaneous affectation with frequent visceral affectation, poor response to treatment and low survival associated to the presence of opportunistic infections. The lower incidence of tumor observed in our study is related to the different distribution of the risk groups for HIV in our country.

Clinical, endoscopic, immunologic, and therapeutic aspects of oropharyngeal and esophageal candidiasis in HIV-infected patients: a survey of 114 cases.

The medical records of 114 consecutive HIV-infected patients with oropharyngeal and esophageal candidiasis, in whom esophagoscopy was performed, were reviewed. Esophageal candidiasis and isolated oral candidiasis were found in 75% and 25% of patients, respectively. Esophageal candidiasis was the AIDS-defining illness in 65 patients and dysphagia was the commonest symptom, but asymptomatic Candida esophagitis was observed in 43% of them. Symptoms were present in six patients with oropharyngeal candidiasis; three of them had a normal esophagoscopy and the other three had acute nonfungal esophagitis. Invasive fungal esophagitis was confirmed by biopsy in 47/74 patients (64%). The patients with esophageal candidiasis had lower CD4+ cell counts (129/microliter) and CD4:CD8 ratios (0.23) than those with oropharyngeal candidiasis (CD4 179/microliter; CD4:CD8 0.35). Thirty-six patients with esophageal candidiasis were treated with fluconazole, 100 mg/daily, for 28 days, and another 34 patients received the same dose for 10 days. A similar efficacy was seen in both regimens, but a higher incidence of oropharyngeal fungal colonization and liver dysfunction was observed in the longer therapy (p < 0.001). We conclude that asymptomatic C. esophagitis is common in HIV-infected patients. Patients with oropharyngeal candidiasis may complain of esophageal symptoms; it could be due to superficial C. infection or another not-identified opportunistic infection. More severe immunologic impairment was required to develop esophageal candidiasis than oropharyngeal candidiasis. A short course of 10 days of fluconazole therapy could be the standard regimen for the treatment of C. esophagitis in AIDS.
