ABSTRACT
HISTORY AND ADMISSION FINDINGS: A 55-year-old woman presented comfortable and well-nourished for a check up. The physical examination remained without pathological results. However lipase parameter in serum was conspicuously elevated we performed an ultrasound examination. EXAMINATIONS: An abdomen sonography revealed besides regular pancreas morphology a hypoechoic lesion of 11 × 10 mm in the liver and multiple hypoechoic inhomgeneous lesions in the spleen. Because of the inhomogeneous results and septa we decided to arrange an abdomen computer tomography (CT) in which the complex of cysts was stated with a size of 59 × 44 mm. As the differential diagnosis of the cysts could be an echinococcosis or amoebic infection we performed a serological analysis at the first appointment and 4 weeks later. Both test results were negative. TREATMENT AND COURSE: Eight years later we indicated a magnetic resonance tomography (MRI with MRCP) to exclude a compression of the pancreatic duct by the splenic or liver cysts because the lipase und C-reactive protein (CRP) in serum was rising up again . The MRI scan showed a progression of the splenic cysts complex to 88 × 69 mm and the liver cyst to 25 × 20 mm without signs for compression or a malignant process. A correlation between elevated lipase and splenic cysts was not evident. Despite progression of the splenic cysts we decided in view of the comfortable condition of the patient and negative serological analysis for a conservative proceeding in terms of regular check ups. CONCLUSION: From our point of view also in extended non-parasitic splenic cysts it is reasonable to follow a nonoperative regime as long as clinical complaints, parasitic genesis and malignant process can be excluded.

The objective of this survey was to investigate qualitative and quantitative properties of meat from organic, free-range, and conventional broilers as currently provided to consumers. Fifteen broilers from 4 suppliers of each type were evaluated for raw meat yield, cooked meat yield, proximate composition, pH, color, lipid oxidation, fatty acid composition, and sensory attributes. Organic broilers yielded more dark (thigh) meat (P < 0.05) than free-range or conventional, when compared on a raw-meat basis, but conventional and free-range broilers yielded more (P < 0.05) cooked light (breast) meat than organic. Protein content of organic breast and thigh meat was greater (P < 0.05) than conventional in the raw and the cooked meat comparisons. The pH of breast meat from organic broilers was higher (P < 0.05) than free-range or conventional. Organic breast and thigh meat was less yellow (P < 0.05) than free-range or conventional. Fatty acid analysis showed that organic breasts and thighs were lower (P < 0.05) in saturated and monounsaturated fatty acids and higher (P < 0.05) in polyunsaturated fatty acids than free-range and conventional broilers. Shear force measurements were less (P < 0.05) for both breast and thigh meat from conventional broilers relative to free-range and organic broilers. Sensory panel results indicated that thighs from conventional broilers were more tender (P < 0.05) and less chewy (P < 0.05) than thighs from free-range and organic broilers, whereas other sensory properties did not differ. At the time of the study, March through May of 2006, the average retail prices for US broilers were USD 3.19, USD 2.78, and USD 1.29 per pound (USD 7.03, USD 6.13, and USD 2.84/kg) for organic, free-range, and conventional, respectively. Whereas a difference in the fatty acid composition was the largest difference observed between retail broilers in this survey, it is important to note that diets and production environments within the study were not controlled. It is apparent that the market prices for broilers at the time of this study are not fully reflected in the quantitative and qualitative measurements included in this study. It appears that consumers may be placing significant value on more intangible attributes associated with broilers marketed as organic and free-range chicken than on those attributes measured in this study.

Cidofovir is an acyclic nucleoside phosphonate with broad-spectrum activity against DNA viruses, including human papilloma virus (HPV). However, data on the efficacy of cidofovir in an immunosuppressive setting remain contradictory. We report for the first time on the promotion of the healing of recalcitrant warts in a patient with myelodysplastic syndrome with intravenous cidofovir treatment.

Severe generalized nodular and bullous mastocytosis of the xanthelasmoid type is described in a 7-month-old boy. Reddish to yellowish-brown xanthelasmoid papules and nodules first developed in the inguinal region a few weeks after birth and then progressively spread to cover nearly the entire body surface. There was severe pruritus and recurrent episodes of blistering. The diagnosis of cutaneous mastocytosis of the xanthelasmoid type with subepidermal bullae was confirmed by skin biopsies showing solid and deeply penetrating infiltrates of metachromatic mast cells under light and electron microscopy. Systemic involvement of other organs, however, was excluded by bone scintigraphy, abdominal ultrasound, bone marrow aspiration and echocardiography. The extensive skin involvement was reflected in highly elevated urinary levels of histamine (263.4 microg L(-1)) and its metabolite N-methylimidazole acetic acid (20.8 mg L(-1)). The patient was systematically well and received only symptomatic treatment. Over a period of 1 year, the condition gradually improved, and the skin lesions began to flatten and regress.

An HIV-1 infected immunosuppressed patient (CD4+ cell counts: 382 cells/microL; viral load 94,000 copies/mL) with recurrent perianal herpes simplex virus type 2 (HSV-2) infections is described, showing an unusual exophytic tumour resembling a squamous cell carcinoma in the lateral part of the tongue. He also had persistent facial herpes infection, oral candidosis, oral hairy leukoplakia and lymphadenopathy. The presence of HSV-2 was detected by polymerase chain reaction both in smears and in a tissue biopsy taken from the involved tongue area. Treatment with brivudin, a new oral virustatic drug, led to rapid regression of the tumour.

Between 1982 and 1995, over 700 HIV-infected patients with different skin diseases were registered at the Department of Dermatology, Benjamin Franklin Medical Center, The Free University of Berlin. Thirty-six of them (approximately 5%) were diagnosed as having psoriasis. This is clearly a higher prevalence of psoriasis than in the general population (1-2%). If psoriasis lesions are not clinically seen before diagnosis of HIV infection, the disease will preferentially (approximately 80% of these cases) appear during the late stages of the infection (CD4/CD8 ratio < 0.4). Six of the 36 patients with HIV-related psoriasis (= 16%) were found to have severe disease, showing an exsudative clinical picture. In this paper we report in detail on two representative cases from this group of patients. Histological examination also revealed exsudative changes in HIV-infected patients with clinically moderate psoriasis. Immunohistochemically, HIV-related psoriasis showed a moderately decreased number of infiltrating T-cells, in contrast to psoriatic skin from non-infected patients. A marked difference was the reduced expression of the lymphocyte antigen OPD-4 in HIV-related psoriasis. Routine antipsoriatic treatment modalities in combination with systemic retinoids and phototherapy (SUP/PUVA) were successful in the treatment of severe exsudative psoriasis in HIV patients, but the course of the disease was prolonged and exacerbation was more frequent. HIV-related psoriasis was found not to influence the underlying HIV infection.

Mollusca contagiosa predominantly affect children; their occurrence in adults is rare. In recent years many descriptions of mollusca contagiosa in immunosuppressed patients, mostly in HIV-infected individuals, have appeared. We analysed the occurrence of mollusca contagiosa in a large group of HIV-patients and examined their relation to the immune status and their prognostic significance. 456 patients with HIV-associated skin disorders were documented in the HIV follow-up clinics at the Department of Dermatology, University Medical Center Benjamin Franklin, Berlin, during the years 1982-1992. Molluscum contagiosum was diagnosed in 39 patients (8.6%). 38 of the 39 patients were homosexual and/or bisexual men. The median age of the patients was 34 years. Large, papular and nodular lesions up to 1 cm in diameter were observed in some, individuals. Frequently, multiple lesions in atypical localizations such as the face were found. Significant immunosuppression was present in the majority of patients with mollusca contagiosa at the time of their first diagnosis; median CD(4+)-T-lymphocyte count was 122/microliter and the median CD4+/CD(8+)-ratio was 0.2. The median survival time was 12 months in patients with mollusca contagiosa. There was no significant difference between the prognosis of patients with mollusca contagiosa and other HIV-infected patients showing similar reduction of their immune status. Our study showed that mollusca contagiosa are a rather frequent infection in HIV-patients. Mainly localized to the face, they are easily diagnosed and may serve as an excellent clinical marker for recognizing advanced immunosuppression in HIV-infection. Survival prognosis of patients with molluscum contagiosum is unfavourable, corresponding to their reduced immune status. The presence of mollusca, however, is not an independent prognostic marker, if the immune status is considered.

BACKGROUND: Oral hairy leukoplakia (OHL) is a benign hyperplasia of the oral mucosa that is induced by Epstein-Barr virus. It occurs nearly exclusively in men infected with HIV. OHL is a marker of moderate to advanced immunodeficiency and disease progression in patients with HIV infection. OBJECTIVE: We attempted to determine the clinical characteristics of OHL in a large group of patients infected with HIV and to analyze its relation to immune status and prognosis. METHODS: A total of 456 patients with HIV-associated skin disorders were evaluated during the years 1982 through 1992. All patients had an oral examination. CD4+ cell counts were obtained within 3 months of the examination. RESULTS: OHL was diagnosed in 15.6% of 456 patients. The median age of the patients was 35 years. OHL was found most often on the lateral aspect of the tongue; in one patient the lesion covered the entire dorsal surface of the tongue. Significant immunosuppression was present in the majority of patients at the time of OHL diagnosis (median CD4+ T-lymphocyte count, 235/microliter; median CD4+/CD8+ ratio, 0.3). The median survival time was 20 months in patients with OHL. In patients with a higher CD4 cell count (CD4+ T lymphocyte count, > or = 300/microliter) the diagnosis of OHL was associated with shorter survival times (median survival time, 25 months) compared with other patients with HIV (median survival time, 52 months). CONCLUSION: OHL is a frequent finding in patients with HIV and indicates advanced immunosuppression. Even in patients with more than 300/microliter CD4+ T lymphocytes, OHL is associated with a poor prognosis.

Kaposi's sarcoma (KS) is a multicentric neoplasia of microvascular origin arising during development of immunodeficiency in human immunodeficiency virus (HIV)-infected individuals. More than 130 patients with HIV-associated KS (98% male homosexuals; median age, 35 years) have been diagnosed at the Department of Dermatology, University Medical Center Steglitz, Berlin, during the years 1982-1992. Mucocutaneous and visceral involvement was a common finding in patients with HIV-associated KS, increasing from 39% at the first visit to 65% at the last observation. In 90% of the patients significant immunosuppression was found (75% had a CD4+ count < 200/mm3) at the time of first diagnosis. However, immunosuppression was not a prerequisite for the development of KS, since the tumor had been diagnosed before severe immunosuppression was present in about 10% of the patients. Significant prognostic predictors for the final outcome were: (a) the degree of immunosuppression, (b) the presence of mucosal and visceral manifestation, and (c) the past history of opportunistic infections. The median survival time was 28 months in KS patients with more than 300 CD4+ lymphocytes (n = 18), but only 14 months in immunosuppressed (less than 300 CD4+ lymphocytes) individuals with KS (n = 70). The median survival time in the entire group evaluated (n = 89 patients) was 17 months after first diagnosis. In 71 HIV-infected individuals who died at the Berlin Department during the last 8 years, disseminated KS was the major direct or indirect cause of death (49% of cases). Therapeutic benefit for KS patients was observed after long-term administration of recombinant interferon alpha (rIFN-alpha; 9-18 million IU s.c. every 2 days) alone or combined with antiretroviral drugs such as zidovudine over several months. Prolongation of survival was found after such treatment modalities in 30%-40% of treated patients. Bleomycin and vincristine and other systemically used cytostatics have also been applied with moderate results. The etiology of HIV-associated KS is still unknown and coinfection with herpes simplex virus (HSV), cytomegalovirus (CMV), or human papillomavirus (HPV) as well as certain growth-stimulating cytokines (transforming growth factors, TGF; tumor necrosis factor alpha, TNF-alpha; interleukin-6, IL-6; tat; vascular endothelial growth factors, VEGF; oncostatin M) produced by HIV-infected cells may be cofactors. Overall, KS was found to be a tumor with high malignant potential, and the median survival times were short.(ABSTRACT TRUNCATED AT 400 WORDS)
