Chemsex and the city: sexualised substance use in gay bisexual and other men who have sex with men attending sexual health clinics.

The objective of this study was to analyse associations between sexualised substance use (chemsex), STI diagnoses and sexual behaviour among gay bisexual and other men who have sex with men accessing sexual health clinics to better inform clinical pathways. A retrospective case notes review was undertaken following the introduction of more detailed and holistic profomas for all gay bisexual and other men who have sex with men attending two London sexual health clinics between 1 June 2014 and 31 January 2015. Chemsex status was documented for 655/818. Overall, 30% disclosed recreational drug use of whom 113 (57%) disclosed chemsex and 27 (13.5%) injecting drugs. HIV-positive gay bisexual and other men who have sex with men were more likely to disclose chemsex (AOR 6.68; 95% CI 3.91-11.42; p < 0.001). Those disclosing chemsex had a higher incidence of acute bacterial STIs (AOR 2.83 CI 1.79-4.47; p < 0.001), rectal STIs (AOR 3.10 CI 1.81-5.32; p < 0.001) or hepatitis C (AOR 15.41 CI 1.50-158.17; p = 0.021). HIV incidence in the study period was 1.8% (chemsex) vs. 0.9% (no chemsex) (p = 0.61). Chemsex was associated with having more sexual partners, transactional sex, group sex, fisting, sharing sex toys, injecting drug use, higher alcohol consumption and the use of 'bareback' sexual networking applications (p < 0.004). Chemsex participants were also more likely to have accessed post-exposure prophylaxis for HIV in the study period and report sex with a discordant HIV or hepatitis C-infected partner (p < 0.001). Chemsex disclosure is associated with higher risk-taking behaviours, acute bacterial STIs, rectal STIs and hepatitis C incidence. HIV incidence was higher but not significantly so in the study period. Chemsex disclosure in sexual health clinics should prompt an opportunity for prevention, health promotion and wellbeing interventions.

Assessment of a rapid liquid-based cytology method for measuring sputum cell counts.

Differential sputum cell counting is not widely available despite proven clinical utility in the management of asthma. We compared eosinophil counts obtained using liquid-based cytology (LBC), a routine histopathological processing method, and the current standard method. Eosinophil counts obtained using LBC were a strong predictor of sputum eosinophilia (≥3%) determined by the standard method suggesting LBC could be used in the management of asthma.

Pulmonary hypertension and interstitial lung disease within PHAROS: impact of extent of fibrosis and pulmonary physiology on cardiac haemodynamic parameters.

OBJECTIVES: We sought to examine the relationship between measures of ILD severity and PH in patients with SSc. METHODS: We identified 55 subjects from 12 PHAROS sites with RHC-proven PH and HRCT evidence of ILD. Subjects with PH due to left heart disease were excluded. Baseline HRCT scans were scored by a standardised system that graded severity of ILD. Summary statistics were generated for baseline characteristics. Spearman correlation and linear regression were used to examine relationships between ILD and PH severity variables. RESULTS: The majority of subjects were white women; nearly half had limited cutaneous SSc. Most subjects were New York Heart Association functional class II or III. Pulmonary function testing revealed moderate restriction (mean FVC 64.3 ± 17.2% predicted) with severe reduction in diffusing capacity (mean DLco 34.2 ± 13.3% predicted). RHC demonstrated mild to moderate PH (mean PAP 35 ± 9 mmHg, mean PVR 5.1 ± 3.7 WU). There was no correlation between severity of ILD (by either HRCT or PFT) and cardiac haemodynamic parameters of PH. CONCLUSIONS: No association between severity of ILD and cardiac haemodynamic profiles were identified in this cohort. We believe this underscores the complex nature of PH and ILD in individuals with SSc. We do suspect that some individuals with SSc-ILD will also have concomitant pulmonary vascular disease but simple assessments to grade severity of ILD - by PFT or HRCT estimates of ILD extent - are likely not enough to reliably distinguish between PAH versus PH-ILD. Further research into how to distinguish and manage these subsets is warranted.

Posttransplant lymphoproliferative disorder presenting as multiple cystic lesions in a renal transplant recipient.

We report a case of a 67-year-old man who experienced allograft dysfunction following a renal transplantation from a donation after cardiac death. The postoperative course was initially complicated by episodes of E. coli urinary sepsis causing pyrexia and a raised creatinine level. Ultrasound scanning 5 weeks posttransplant revealed mild hydronephrosis with several parenchymal cystic areas measuring up to 2 cm with appearances suggestive of fungal balls. Aspirated fluid again grew Escherichia coli, and this was treated with the appropriate antimicrobial therapy. The patient continued to have episodes of culture-negative sepsis; therefore, a computed tomography scan was performed 6 months posttransplant, which revealed multiple lesions in the renal cortex as well as liver and spleen. Subsequent biopsy revealed an Epstein-Barr virus-driven lymphoproliferation consistent with a polymorphic posttransplantation lymphoproliferative disorder (PTLD). This rare case of PTLD presenting as multiple renal, hepatic and splenic lesions emphasizes the need for a high index of clinical suspicion for this condition. Abnormal para-renal allograft masses should be biopsied to allow swift and effective management of a disease that can disseminate and become significantly more challenging to manage.

Effects of Helicobacter pylori, geohelminth infection and selected commensal bacteria on the risk of allergic disease and sensitization in 3-year-old Ethiopian children.

BACKGROUND: Epidemiological studies have suggested that gastro-intestinal infections including Helicobacter pylori, intestinal microflora (commensal bacteria) and geohelminths may influence the risk of asthma and allergy but data from early life are lacking. OBJECTIVE: We aimed to determine the independent effects of these infections on allergic disease symptoms and sensitization in an Ethiopian birth cohort. METHODS: In 2008/09, 878 children (87% of the 1006 original singletons in a population-based birth cohort) were followed up at age 3 and interview data obtained on allergic symptoms and potential confounders. Allergen skin tests to Dermatophagoides pteronyssinus and cockroach were performed, levels of Der p 1 and Bla g 1 in the child's bedding measured and stool samples analysed for geohelminths and, in a random subsample, enterococci, lactobacilli, bifidobacteria and H. pylori antigen. The independent effects of each exposure on wheeze, eczema, hayfever and sensitization were determined using multiple logistic regression. RESULTS: Children were commonly infected with H. pylori (41%; 253/616), enterococci (38.1%; 207/544), lactobacilli (31.1%; 169/544) and bifidobacteria (18.9%; 103/544) whereas geohelminths were only found in 8.5% (75/866). H. pylori infection was associated with a borderline significant reduced risk of eczema (adjusted OR 0.49, 95% CI 0.24-1.01, P=0.05) and D. pteronyssinus sensitization (adjusted OR 0.42, 95% CI 0.17-1.08, P=0.07). Geohelminths and intestinal microflora were not significantly associated with any of the outcomes measured. CONCLUSION AND CLINICAL RELEVANCE: Among young children in a developing country, we found evidence to support the hypothesis of a protective effect of H. pylori infection on the risk of allergic disease. Further investigation of the mechanism of this effect is therefore of potential therapeutic and preventive value.

Distinct evolution of TLR-mediated dendritic cell cytokine secretion in patients with limited and diffuse cutaneous systemic sclerosis.

BACKGROUND: Systemic sclerosis (SSc) is an autoimmune disease and accumulating evidence suggests a role for Toll-like receptor (TLR)-mediated activation of dendritic cells (DCs). OBJECTIVE: To map TLR-mediated cytokine responses of DCs from patients with SSc. METHODS: 45 patients with SSc were included. Patients were stratified as having diffuse cutaneous SSc (dSSc) or limited cutaneous SSc (lSSc) according to the extent of skin involvement, and further divided into those with late (>3 years) or early disease (<2 years). DCs were stimulated with ligands for TLR2, TLR3, TLR4, TLR7/8 or combinations. Plasma samples were collected from patients with SSc (n=167) and measured for interleukin 6 (IL-6), tumour necrosis factor alpha (TNFalpha), IL-12, IL-10 and interferon gamma. RESULTS: Stimulation of DC subsets from patients with early lSSc and dSSc with ligands for TLR2, TLR3 or TLR4 resulted in higher secretion of IL-6 and TNFalpha compared with those having late disease or healthy controls. Remarkably, the production of IL-12 was lower upon stimulation with TLR ligands in most patients with SSc, whereas the secretion of IL-10 was very high in patients with the dSSc phenotype, particularly in those having early dSSc. The combination of various TLR ligands led to reduced cytokine secretion in all patients with SSc. Circulating levels of these cytokines further underscored the presence of differences between various SSc phenotypes. DISCUSSION: The altered TLR-mediated activation of DCs may be responsible for Th2 skewed T-cell activation in SSc that may be orchestrated by fibrogenic T-cell cytokines, such as IL-4 and IL-13. DC targeting could thus offer new avenues for therapeutic intervention.

Management and outcome of pregnancies with parvovirus B19 infection over seven years in a tertiary fetal medicine unit.

OBJECTIVES: To determine rates of fetal anaemia and pregnancy outcome in susceptible pregnant women infected with human parvovirus B19 infection in a tertiary fetal medicine department over a 7-year period. Additional features enabling identification of fetuses that progress to severe anaemia were also investigated. METHODS: Forty-seven susceptible, pregnant women with confirmed parvovirus infection referred to a regional fetal medicine unit, over a 7-year period (1999-2006), were identified. Where possible maternal serum AFP measurements were obtained from second-trimester serum screening and the presence or absence of echogenic bowel noted. RESULTS: Of the 47 cases, one was excluded. Of the remaining 46 cases, 34 (74%) showed no signs of fetal anaemia and delivered at term. The remaining 12 (26%) showed signs of fetal anaemia. Eight of the 12 developed hydrops and underwent fetal blood sampling and transfusion (median pretransfusion Hb 3.6 g/dl). Seven of the 8 transfused fetuses were thrombocytopenic with a platelet count <150 x 10(9)/l, with 2 fetuses having platelet counts <50 x 10(9)/l. The median gestation age at transfusion was 22 weeks (range 18-27 weeks). The median number of weeks between seroconversion and transfusion was 6 (range 3-12). The signs of anaemia resolved after one transfusion in 5 of the 8 transfused fetuses and they subsequently delivered at term. There were 2 fetal deaths during or shortly after transfusion and one neonatal death following delivery at 28 weeks gestation due to severe pre-eclampsia, 5 days after successful transfusion. CONCLUSIONS: Following parvovirus seroconversion, the incidence of significant fetal anaemia requiring transfusion was 17%. Seroconversion after 21 weeks did not result in severe fetal anaemia. Significant anaemia requiring intervention did not occur 12 weeks after maternal seroconversion. We did not demonstrate a correlation with either maternal serum AFP or the presence of fetal echogenic bowel and the development of severe fetal anaemia. Because of the association between fetal anaemia and severe thrombocytopenia, it may be prudent to have compatible platelets available at the time of fetal blood sampling.

Digital ulcers in systemic sclerosis: prevention by treatment with bosentan, an oral endothelin receptor antagonist.

OBJECTIVE: Recurrent digital ulcers are a manifestation of vascular disease in patients with systemic sclerosis (SSc; scleroderma) and lead to pain, impaired function, and tissue loss. We investigated whether treatment with the endothelin receptor antagonist, bosentan, decreased the development of new digital ulcers in patients with SSc. METHODS: This was a randomized, prospective, placebo-controlled, double-blind study of 122 patients at 17 centers in Europe and North America, evaluating the effect of treatment on prevention of digital ulcers. The primary outcome variable was the number of new digital ulcers developing during the 16-week study period. Secondary assessments included healing of existing digital ulcers and evaluation of hand function using the Scleroderma Health Assessment Questionnaire. RESULTS: Patients receiving bosentan had a 48% reduction in the mean number of new ulcers during the treatment period (1.4 versus 2.7 new ulcers; P = 0.0083). Patients who had digital ulcers at the time of entry in the study were at higher risk for the development of new ulcers; in this subgroup the mean number of new ulcers was reduced from 3.6 to 1.8 (P = 0.0075). In patients receiving bosentan, a statistically significant improvement in hand function was observed. There was no difference between treatment groups in the healing of existing ulcers. Serum transaminase levels were elevated to >3-fold the upper limit of normal in bosentan-treated patients; this elevation is comparable with that observed in previous studies of this agent. Other side effects were similar in the 2 treatment groups. CONCLUSION: Endothelins may play an important role in the pathogenesis of vascular disease in patients with SSc. Treatment with the endothelin receptor antagonist bosentan may be effective in preventing new digital ulcers and improving hand function in patients with SSc.

Hamartoma of the breast in a man: first case report.

Mammary hamartomas were reported in 0.7% of all benign tumors of the female breast. Histologically breast hamartomas contain lobular breast tissue with various degrees of fibrous, fibrocystic, and adipose tissue. Rare types include muscular (myoid) and cartilage (chondroid) hamartomas. We report a case of muscular hamartoma in a man. A 36-year-old man was admitted to the psychiatric unit with the diagnosis of schizophrenia. The patient complained of a slowly growing mass in his left breast. He denied any discharge from the nipple, but he complained of itching. A 2 cm x 3 cm nontender mass was palpable. There was no evidence of axillary lymphadenopathy. A needle aspiration was nondiagnostic. The excisional biopsy specimen revealed fatty tissue which was edematous and hemorrhagic. Microscopically it showed multiple bundles of muscles organized randomly. Myoid hamartoma was the diagnosis. Mammary hamartoma is considered a female tumor exclusively. Myoid hamartoma has been reported previously in 25 women. We report a myoid hamartoma in a man and, to our knowledge, it is the first and only such case to be reported.

Results of a phase-I/II randomized, masked, placebo-controlled trial of recombinant human interleukin-11 (rhIL-11) in the treatment of subjects with active rheumatoid arthritis.

Interleukin-11 (IL-11) is a pleiotropic cytokine that regulates the growth and development of hematopoietic stem cells and decreases the proinflammatory mediators of cytokine and nitric oxide production. In animal models of arthritis, treatment with recombinant human IL-11 (rhIL-11) reduces both the level of synovitis and the histologic lesion scores in the joints. The goal of this phase-I/II study in adults with rheumatoid arthritis (RA) was to evaluate the safety and clinical activity of different doses and schedules of rhIL-11 in patients with active RA for whom treatment with at least one disease-modifying antirheumatic drug had failed. This was a multicenter, randomized, placebo-controlled trial that evaluated the safety and tolerability of rhIL-11 in 91 patients with active RA. rhIL-11 was administered subcutaneously; patients were randomized into one of five treatment groups (ratio of rhIL-11 to placebo, 4:1). Patients were treated for 12 weeks with either 2.5 or 7.5 microg/kg of rhIL-11 or placebo twice per week or 5 or 15 microg/kg of rhIL-11 or placebo once per week. The status of each subject's disease activity in accordance with the American College of Rheumatology (ACR) criteria was assessed before, during, and after completion of administration of the study drug. Administration of rhIL-11 was well tolerated at all doses and schedules. The most frequent adverse event was a reaction at the injection site. The data suggest a statistically significant reduction in the number of tender joints (P < 0.008) at the 15 microg/kg once-weekly dose schedule but showed no overall significant benefit at the ACR criterion of a 20% response. The trial showed rhIL-11 to be safe and well tolerated at a variety of doses and schedules over a 12-week treatment period in patients with active RA. The only adverse event clearly associated with rhIL-11 administration was reaction at the injection site.

Controlled-risk foreign investment strategy can boost yields.

Healthcare organizations that have invested in the U.S. stock market have enjoyed high returns in recent years. After such a performance, many investment managers see little reason to investigate overseas markets, believing that the U.S. market will continue to be profitable and economic uncertainties make overseas markets too risky. However, in 1999, markets in Europe, Australia, and the Far East outperformed the S&P 500 for the first time in five years. In addition, signs such as mounting price/earnings ratios may indicate that the U.S. stock market will be less profitable than it has been in recent years. Consequently, investment managers should revisit the idea of international investing.

Recombinant human relaxin in the treatment of scleroderma. A randomized, double-blind, placebo-controlled trial.

BACKGROUND: Relaxin is a pregnancy-related hormone that has tissue remodeling and antifibrotic effects. Systemic sclerosis (scleroderma) is characterized by fibrosis of the skin, vasculature, and internal organs. OBJECTIVE: To assess the efficacy, safety, and dose-response effect of recombinant human relaxin in patients with scleroderma. DESIGN: Multicenter, parallel-group, randomized, double-blind, placebo-controlled trial. SETTING: Academic referral centers. PATIENTS: 68 patients who had had stable, diffuse scleroderma (moderate to severe) for less than 5 years. INTERVENTION: Recombinant human relaxin, 25 or 100 microg/kg of body weight per day, or placebo administered by continuous subcutaneous infusion over 24 weeks. MEASUREMENTS: Modified Rodnan skin score was the primary efficacy measure. Secondary measurements were pulmonary function, the Health Assessment Questionnaire, and other measures of scleroderma that reflected fibrosis. RESULTS: Patients who received 25 microg/kg of recombinant human relaxin per day had significantly lower skin scores than those who received placebo (mean change, -3.6 at 4 weeks [P = 0.021], -7.5 at 12 weeks [P < 0.001], and -8.7 at 24 weeks [P = 0.040]). Similar trends were noted in other outcome measures, including forced vital capacity, measures of oral aperture and hand extension, functional status, and global assessment. Patients who received 100 microg/kg of relaxin per day did not differ from those who received placebo. Drug-related adverse events included menometrorrhagia, reversible anemia, and complications of the subcutaneous drug administration system (site irritation and local infection). CONCLUSIONS: Twenty-four weeks of recombinant human relaxin, 25 microg/kg per day, is associated with reduced skin thickening, improved mobility, and improved function in patients with moderate to severe diffuse scleroderma.

The role of vitamin D in corticosteroid-induced osteoporosis: a meta-analytic approach.

OBJECTIVE: To determine if vitamin D is more effective than no therapy or calcium alone in the management of corticosteroid-induced osteoporosis, and to determine how vitamin D compares with other osteoporosis therapies, e.g., bisphosphonates, calcitonin, or fluoride, for this condition. METHODS: We evaluated all formulations of vitamin D, including its active metabolites and analogs. A systematic search for published and unpublished studies was conducted using MEDLINE (1966-December 1997), bibliographic references, abstracts from proceedings of recent national meetings, and contact with pharmaceutical companies and content experts. We included all randomized controlled trials lasting at least 6 months (and reporting extractable results), of patients receiving oral corticosteroids, that compared vitamin D with either 1) no therapy or calcium alone, or 2) bisphosphonates, calcitonin, or fluoride. The primary outcome measure of interest was change in lumbar spine bone mineral density. RESULTS: We found a moderate beneficial effect of vitamin D plus calcium versus no therapy or calcium alone (9 trials) (effect size 0.60; 95% confidence interval [95% CI] 0.34, 0.85; P < 0.0001). In comparisons of vitamin D with other osteoporosis therapies, bisphosphonates were more effective than vitamin D (6 trials) (effect size 0.57; 95% CI 0.09, 1.05). Calcitonin was similar in efficacy to vitamin D (4 trials) (effect size 0.03; 95% CI -0.39, 0.45). Fluoride was more effective than vitamin D, but there were only 2 trials. CONCLUSION: Vitamin D plus calcium is superior to no therapy or calcium alone in the management of corticosteroid-induced osteoporosis. Vitamin D is less effective than some osteoporosis therapies. Therefore, treatment with vitamin D plus calcium, as a minimum, should be recommended to patients receiving long-term corticosteroids.

Systemic sclerosis-associated pulmonary hypertension: short- and long-term effects of epoprostenol (prostacyclin).

OBJECTIVE: To evaluate the short- and long-term effects of intravenous epoprostenol in patients with pulmonary hypertension (PH) associated with systemic sclerosis (SSc). METHODS: Sixteen patients with SSc-associated PH and New York Heart Association (NYHA) class III or IV symptomatology underwent right heart catheterization for determination of baseline hemodynamic values. Vasoreactivity was assessed with either inhaled nitric oxide or intravenous adenosine. After a medication washout period, all patients received intravenous epoprostenol in incrementally increasing doses; tolerance was assessed according to symptoms and hemodynamic findings at each dose increment and at the conclusion of the medication trial. Once a stable medication regimen was established, patients were discharged and followed up as outpatients for assessment of symptoms and exercise tolerance as measured by change in the NYHA class. Repeat hemodynamic testing was performed in 4 patients at 1 year and in 2 patients at 2 years of treatment. RESULTS: Therapeutic response to epoprostenol, defined by a reduction in the pulmonary vascular resistance of > or =25%, was achieved in the short-term treatment period in 13 of 16 patients (81.3%). Improvement in symptoms and exercise tolerance occurred in all patients, and a significant short-term hemodynamic response was observed. Followup hemodynamic tests revealed persistent favorable responses in all 4 of the patients studied. CONCLUSION: Most patients with PH secondary to SSc manifest favorable hemodynamic responses to epoprostenol in the short term. Long-term epoprostenol was generally well tolerated and provides a potential therapeutic option for patients with PH secondary to SSc.

Fibromyalgia is not a muscle disorder.

Originally described as "fibrositis," fibromyalgia has long been considered a muscle disorder, and many studies have investigated the possible pathologic basis of the disorder by examining muscle tissue, using various methodologic approaches. Although initial studies suggested a possible pathologic basis in muscle, most had serious methodologic limitations. More recent studies, however, have avoided methodologic pitfalls and indicate that the muscles of patients with fibromyalgia are normal. When data from studies of tenderness are also taken into account, the weight of evidence suggests that fibromyalgia is a chronic pain syndrome which has a central rather than peripheral or muscular basis.

Oral iloprost treatment in patients with Raynaud's phenomenon secondary to systemic sclerosis: a multicenter, placebo-controlled, double-blind study.

OBJECTIVE: To evaluate the efficacy and tolerability of an oral preparation of iloprost, a prostacyclin analog, in patients with Raynaud's phenomenon (RP) secondary to systemic sclerosis (scleroderma). METHODS: A multicenter, randomized, parallel-group, placebo-controlled double-blind study was performed at university and community-based medical centers. Patients were randomly assigned to receive either 50 microg of iloprost orally twice daily or an identical gelatin-coated capsule containing placebo for 6 weeks. Outcome measures included average total daily duration of RP attacks, average number of RP attacks, and RP condition scored via a standardized daily diary. RESULTS: Three hundred eight patients with scleroderma (272 women, 36 men, mean age 49 years [range 18-80]) were enrolled. One hundred fifty seven were assigned to receive iloprost and 151 to receive placebo. One hundred forty-three patients in the iloprost group (91.1%) and 144 in the placebo group (95.4%) completed the 6-week treatment phase. Fifteen of these treated patients (8 iloprost, 7 placebo) failed to complete all of the followup visits. The mean reduction in the average duration of attacks from baseline to week 5-6 was 24.32 minutes in the iloprost group and 34.34 minutes in the placebo group (P = 0.569). Likewise, the mean reduction from baseline to week 5-6 in the daily frequency of attacks was 1.02 in the iloprost group and 0.83 in the placebo group (P = 0.459). The Raynaud's condition score, a patient-completed assessment of the severity of RP attacks, was reduced by 1.32 in the iloprost group and 1.00 in the placebo group (P = 0.323). The lack of significant difference between treatment groups did not change when a variety of factors, including use of other vasodilators, duration of disease, classification of scleroderma (limited versus diffuse), or number of baseline digital ulcers were taken into account. Premature withdrawal from the study due to adverse events occurred in 10 patients (6.4%) in the iloprost group and 3 (2.0%) in the placebo group (P = 0.058). CONCLUSION: Oral iloprost at a dosage of 50 microg twice daily is no better than placebo for management of RP secondary to scleroderma, either during 6 weeks of treatment or during 6 weeks of posttreatment followup.

Scintigraphic functional hyposplenism in amyloidosis.

UNLABELLED: Functional asplenia or hyposplenism may predispose patients to spontaneous splenic rupture and potentially increase the risk of serious infection. In addition, hyposplenism may be a marker of more extensive systemic amyloidosis and has been correlated to a reduction in survival. Decreased splenic function is generally diagnosed by the presence of abnormal red blood cell morphology and decreased splenic uptake on 99mTc-sulfur colloid or microlite scans. We compared liver spleen scans with red cell morphology and anatomic imaging results in all patients with biopsy-proven amyloidosis who presented to the nuclear medicine department over a 12-yr period. Patients were referred from a center for amyloid disease for work-up of suspected hepatic involvement. METHODS: Between 1983 and 1995, 23 liver spleen scans from 21 patients (one patient had three scans) with known amyloidosis were referred for the assessment of degree of hepatic involvement with amyloid. All scans were retrospectively reviewed, and the degree of splenic uptake was graded. Medical records were reviewed for evidence of splenomegaly on physical exam. Extent of splenic involvement also was assessed by anatomical imaging (CT or MRI) in 45% of cases. Peripheral smear reports were reviewed for the presence of abnormal red cell morphology consistent with hyposplenism. RESULTS: Splenic activity was moderately or markedly reduced in 22 of 23 liver spleen scans (21 patients). Eight of these scans had correlative anatomic splenic imaging: four were abnormal and four were normal. Forty-one percent of available peripheral smears contained abnormal red cell morphology. Nine patients had palpable splenomegaly at the time of the liver spleen scan. Splenic pathologic studies were available for three patients (two autopsy, one surgical) and demonstrated diffuse splenic infiltration with amyloidosis. One patient had spontaneous splenic rupture. Fourteen patients died, four of overwhelming infection. CONCLUSION: Reduced splenic uptake on liver spleen scans for patients with suspected hepatic infiltration with amyloid is a common finding. Liver spleen scanning appears to be a more sensitive marker of splenic amyloidosis than clinical parameters or anatomical imaging.

Extensive mesenteric inflammatory veno-occlusive disease of unknown etiology after primary cytomegalovirus infection: first case.

We report a young man who, shortly after a primary cytomegalovirus infection, presented with signs of intestinal ischemia requiring surgical intervention. The resected specimen of small bowel showed striking features of extensive phlebitis and venulitis affecting virtually all of the veins of the small intestine and mesentery. Although he had had a recent primary cytomegalovirus viremia, we could not identify any evidence of cytomegalovirus in the small bowel. He was not infected with HIV. The entity we describe is different from the recently reported mesenteric inflammatory veno-occlusive disease. The clinicopathologic entity represented by our patient's disease was heretofore unrecognized.
