1/61. Differentiating hiv-1 parotid cysts from papillary cystadenoma lymphomatosum.BACKGROUND: patients with parotid cystic lesions may first be seen in the dental office. These conditions most often represent either papillary cystadenoma lymphomatosum, or PCL, or lymphoepithelial cysts associated with human immunodeficiency virus, or HIV, disease. The authors present a case report to illustrate the differential diagnosis. CASE DESCRIPTION: PCL represents a benign, usually unilateral, circumscribed parotid tumor with cystic elements. HIV-associated lymphoepithelial cysts of the parotid gland usually are seen bilaterally, create cosmetic concerns and are hallmarked by an associated cervical lymphadenopathy. Therapy for PCL demands surgical excision, while patients with HIV-associated lymphoepithelial cysts may be treated with antiviral therapy and undergo periodic monitoring by a physician. CLINICAL IMPLICATIONS: As a member of the health care team, the dentist must be familiar with head and neck swellings. Early clinical recognition of parotid swellings leads to successful treatment.- - - - - - - - - - ranking = 1keywords = immunodeficiency (Clic here for more details about this article) |
2/61. Hormonal and immunological pattern in a patient with acquired immunodeficiency syndrome related complex and Cushing's syndrome.A case of Cushing's syndrome in a 24-yr-old homosexual with an aids-related complex is reported. In this patient certain symptoms common to both diseases, i.e. weakness, myalgia and muscle atrophy were accentuated, whereas other symptoms pathognomic of the human immunodeficiency virus (HIV) infection, i.e. lymphoadenopathies and weight loss, were less pronounced by the high levels of circulating adrenal steroids. ketoconazole was administered po in order to block adrenal steroidogenesis, the drug caused a remarkable fall of cortisol serum concentrations, but was unable to modify significantly the immunological pattern of the patient. Our data suggest that changes of serum adrenal steroid levels have little effect on the immune network of patients with AIDS.- - - - - - - - - - ranking = 18.958787765953keywords = immunodeficiency syndrome, immunodeficiency (Clic here for more details about this article) |
3/61. Unusual skin pigmentation in a patient with human immunodeficiency virus (HIV) infection.Diffuse addisonian hyperpigmentation in a male patient with acquired immunodeficiency syndrome related complex (ARC) is described. The etiology of pigmentation in this patient remains obscure but is most probably related to the H.I.V. infection. Other causes of addisonian hyperpigmentation are considered less likely.- - - - - - - - - - ranking = 8.4896969414882keywords = immunodeficiency syndrome, immunodeficiency (Clic here for more details about this article) |
4/61. aids-related complex treated by antiviral drugs and allogeneic bone marrow transplantation following conditioning protocol with busulphan, cyclophosphamide and cyclosporin.A 26-year-old man with aids-related complex (ARC) was treated with high-dose busulphan and cyclophosphamide, followed by allogeneic bone marrow transplantation. For 3 months before transplantation he received a combination of four drugs considered active against human immunodeficiency virus (HIV) to reduce the viral burden: zidovudine, acyloguanosine, fusidic acid and phenylidantoin. Although in reduced doses in coincidence with marrow engraftment, zidovudine therapy was scheduled after transplantation in order to protect donor cells from infection with HIV. Engraftment rapidly occurred and was documented by cytogenetic analyses. The post-transplant course was characterized by severe acute GvHD with irreversible hepatorenal failure. The patient died on day 48 after transplantation. polymerase chain reaction analyses for detecting HIV dna showed the persistence of positivity at day 30 and 45 after transplantation. Antibodies to specific HIV proteins evaluated with Western blot testing also persisted at days 21 and 35 after transplantation. Circulating immunocomplexes disappeared on day 31, and an increase in the CD4/CD8 ratio occurred. The short survival of the patient, affected by chronic hepatitis too, does not allow final conclusions about the role of BMT in HIV disease.- - - - - - - - - - ranking = 1keywords = immunodeficiency (Clic here for more details about this article) |
5/61. Toxic epidermal necrolysis due to vancomycin.Toxic epidermal necrolysis due to vancomycin is reported in a patient with human immunodeficiency virus infection. The same patient had anaphylaxis to cloxacillin but tolerated other penicillin derivatives. These reactions were documented using in vivo and in vitro tests. The role of human immunodeficiency virus infection in the pathogenesis of these reactions is discussed.- - - - - - - - - - ranking = 2keywords = immunodeficiency (Clic here for more details about this article) |
6/61. epidermodysplasia verruciformis-associated papillomavirus infection complicating human immunodeficiency virus disease.Three males infected with the human immunodeficiency virus (HIV) were noted to have extensive flat warts of the face and/or body. In two there were also pityriasis versicolor-like lesions. Biopsies showed foamy, basophilic, distended cytoplasm in granular layer keratinocytes, characteristic of the human papillomavirus types seen in epidermodysplasia verruciformis. dna hybridization techniques demonstrated the presence of HPV-type 8 in one patient and HPV 5 and 8 in another. patients with immune suppression due to HIV infection may demonstrate the clinical features of epidermodysplasia verruciformis with the same potentially oncogenic HPV types.- - - - - - - - - - ranking = 5keywords = immunodeficiency (Clic here for more details about this article) |
7/61. Rectourethral fistula caused by Kaposi's sarcoma.A 35-year-old man with the acquired immunodeficiency syndrome-related complex was evaluated for a persistent urethral discharge, pneumaturia and watery diarrhea. Radiographic and endoscopic procedures established the diagnosis of a rectourethral fistula. Perineal exploration and excision of the fistula revealed the pathological diagnosis of Kaposi's sarcoma. The differential diagnosis of an acquired rectourethral fistula and the significance of Kaposi's sarcoma are discussed.- - - - - - - - - - ranking = 4.4896969414882keywords = immunodeficiency syndrome, immunodeficiency (Clic here for more details about this article) |
8/61. Keratotic papules and nodules and hyperkeratosis of palms and soles in a patient with tuberculosis and aids-related complex.patients with acquired immunodeficiency syndrome (AIDS) and aids-related complex are subject to exaggerated clinical expression of infectious diseases. Widespread keratotic papules and striking hyperkeratosis of the palms and soles went unrecognized as a manifestation of tuberculosis, thereby delaying treatment in a patient with aids-related complex. Reliance on special stains from skin or lymph nodes to diagnose tuberculosis is inappropriate because organisms may not be detected and culture of the organism from the skin may be difficult.- - - - - - - - - - ranking = 4.4896969414882keywords = immunodeficiency syndrome, immunodeficiency (Clic here for more details about this article) |
9/61. Bilateral synchronous testis tumors of different histology in a patient with the acquired immunodeficiency syndrome related complex.The incidence of bilateral testis tumors is approximately 1.5%. Of these cases the majority have the same histological status and few occur synchronously. Recently, an increased number of nonseminomatous germ cell tumors have been reported in the acquired immunodeficiency syndrome population. We describe a rare case of bilateral synchronous testis tumors of different histological status (seminoma and embryonal cell carcinoma) in a patient with the acquired immunodeficiency syndrome related complex. The patient was managed with bilateral orchiectomy and retroperitoneal lymph node dissection. Pathological stage was B1. The treatment was complicated by the fact that the patient is on azidothymidine, a drug that causes bone marrow suppression as a side effect. Because of persistent neutropenia no chemotherapy was given. The patient had no evidence of disease almost 1 year after retroperitoneal lymph node dissection.- - - - - - - - - - ranking = 26.938181648929keywords = immunodeficiency syndrome, immunodeficiency (Clic here for more details about this article) |
10/61. HIV-associated autoimmune hemolytic anemia: report of a case and review of the literature.While anemia and a positive direct anti-globulin test are each frequently observed in the clinical syndrome of human immunodeficiency virus (HIV) infection, autoimmune hemolytic anemia has rarely been reported in this setting. A case of severe warm autoimmune hemolytic anemia (AIHA) with reticulocytopenia in a patient with aids-related complex is reported. Laboratory and clinical findings of severe hemolysis were present, including anhaptoglobinemia, microspherocytosis, splenomegaly, and transfusion dependence. Azidothymidine (AZT) therapy may have exacerbated this patient's anemia. splenectomy produced a delayed but complete remission of the AIHA despite continuation of AZT therapy. review of other reports of positive direct antiglobulin tests and autoimmune hemolytic anemia in patients with hiv infections suggests that autoantibodies may be a significant cause of anemia in this population and that the frequent lack of reticulocytosis, despite bone marrow erythroid hyperplasia, may lead to the underdiagnosis of AIHA in HIV-infected patients.- - - - - - - - - - ranking = 1keywords = immunodeficiency (Clic here for more details about this article) |
