IgD Plasma Cell Neoplasia: Clinical Manifestations and Characteristic Features

Three patients, one with plasma cell leukemia and clinically asymptomatic hypernephroma and meningioma, and two others with multiple myeloma, had M-components of IgD/λ type. In the first case, IgD globulin was found in the serum, ascitic and pleural fluids. Including our patients, 50 cases of IgD myeloma have been reported in the literature. A review of this group showed some significant differences from the other classes of multiple myeloma. IgD myeloma seems to involve a larger proportion of younger people, 66% being less than 59 years of age. The involvement of internal organs and renal damage were more frequent in IgD myeloma than in other classes. Serum total protein was frequently not increased, the relative concentration of M-component was often low and in 12% there was no spike in electrophoresis. The diagnosis therefore was sometimes difficult. In a quarter of the cases Bence Jones proteinemia was found and in 15% there were multiple spikes, both these manifestations being rare in IgG or IgA classes of myeloma. In 89%, IgD globulin had lambda type light chain, clearly contrasting with the figure of approximately 30% in other classes. Bence Jones protein was found in the urine in 91%. The survival time seemed to be shorter than in other myelomas.     

Long-term results of endovascular treatment of metastatic renal cell cancer

The authors analyse the long-term results of treatment of 106 patients with advanced renal cell carcinoma. The patients were divided in two groups. Group 1 (42 patients) included cases with single metastatic lesion. Patients of group 2 (n = 64) had more than one site of metastases. All patients were treated by nephrectomy, embolization with chemotherapeutic agent or arterial occlusion without cytostatic drug except nine patient of group 2, who has undergone chemo and hormonal therapy. The survival according to method at treatment was studies. After occlusion satisfactory results were obtained in cases with single metastasis lesion and also in cases with many sites of metastases. Oily chemoembolization in renal cell carcinoma with distant metastases has given better results as compared with the embolization without chemodrugs. We conclude that endovascular method of treatment is an alternative to the traditional nephrectomy in palliation of renal cell carcinoma.     

Methodichlorophen as anti-tumor drug.

Methodichlorophen was given to 26 patients with terminal malignant disease. Eight patients received adequate doses, and five of them showed objective evidence of tumour regression while three failed to respond. Those who responded included four out of five patients with lung cancer (three with squamous-cell carcinoma and one with oat-cell carcinoma) and a patient with hypernephroma. Two patients with testicular teratomas and one with acute myeloid leukemia failed to respond. The drug may be given safely by mouth to outpatients if certain precautions are taken.     

Adjuvant liver perfusion in colorectal cancer: initial results of a clinical trial.

Fifty consecutive patients with colorectal cancer but no evidence of secondary deposits in the liver were included in an ongoing controlled clinical trial of adjuvant liver perfusion aimed at reducing the incidence of hepatic metastases. All patients had their primary tumour resected in the standard way. Twenty-six of the patients served as controls, and 24 received fluorouracil, 1 g daily, as a continuous infusion into the portal venous system during the first seven days after operation. The patients were matched for age, sex, and site and stage of the disease. The immediate postoperative mortality and morbidity did not differ significantly between the two groups. During the follow-up period (mean duration 15.5 months), however, six deaths occurred in the control group and only one in the perfusion group. At necropsy four of the controls had multiple liver metastases. Two of the surviving controls developed evidence of liver metastases, and two had a local recurrence. No patient in the perfusion group developed evidence of hepatic metastases. These initial results suggest that adjuvant portal venous perfusion with fluorouracil may reduce the incidence of liver metastases in colorectal cancer.

Invasive aspergillosis with extrapulmonary involvement: pathogenesis, clinical characteristics and prognosis

BackgroundThe incidence of invasive aspergillosis has increased worldwide. Information regarding the clinical characteristics of patients with extrapulmonary involvement is scarce.ObjectiveWe aimed to describe the pathogenesis, characteristics and outcomes of patients with invasive aspergillosis and extrapulmonary disease.MethodsA retrospective study conducted in a university hospital in Barcelona, Spain (1995-2011).ResultsA total of 12 cases of invasive aspergillosis and extrapulmonary involvement were found. The most common clinical manifestations were invasive sinusitis, early postoperative prosthetic valve endocarditis, fungaemia, postoperative meningitis, multiple brain abscesses and lumbar spondylitis with epidural abscess. Sinusitis occurred frequently in patients without immunosuppression and had invasive brain involvement in one case. Endocarditis was associated with multiple septic metastases. Concomitant lung involvement was documented in 5 cases. The strains isolated were Aspergillus fumigatus (5), Aspergillus flavus (3), and Aspergillus niger (2). The species of Aspergillus was not established for 3 isolates. All patients were treated with antifungals and surgery was performed in 8 cases. Outcome was related with the source of infection; all patients with invasive sinusitis survived, while the remaining patients had a high mortality rate (88%).ConclusionsInvasive aspergillosis with extrapulmonary involvement is rare. The most common presentation is invasive sinusitis, which has a lower mortality. Other clinical forms with extrapulmonary involvement were associated with severe immunosuppression or previous surgery, and had a poor outcome.

为提高对肺炎克雷伯菌感染所致肝脓肿侵袭综合征的临床表现及其危害的认识,回顾性分析3例确诊为肺炎克雷伯菌感染所致肝脓肿患者的临床经过、治疗反应及转归。结果发现3例患者均有肝外播散性病灶,符合肝脓肿侵袭综合征的临床特征。这3例患者为社区获得性感染,均有肝脓肿,其中2例合并眼内炎并造成失明,1例合并腰椎感染、腹主动脉感染及感染性心内膜炎。2例有糖尿病病史,1例免疫正常。结合文献复习,发现肺炎克雷伯菌感染引起肝脓肿及肝外播散性病灶,临床上称为肝脓肿侵袭综合征,大多由高毒力肺炎克雷伯菌引起,好发于糖尿病及免疫缺陷人群,也可发生于免疫正常人群,治疗困难,临床危害严重,需引起重视。     

Role of hepatic arterial embolisation in the carcinoid syndrome.

Eighteen patients with severe symptoms of the carcinoid syndrome were assessed for hepatic embolisation. Four were too ill, and one had mild symptoms; thus 13 received a periembolisation regimen of cyproheptadine, fenclonine, aprotinin, methylprednisolone, tobramycin, flucloxacillin, and metronidazole. Embolisation was not performed in one patient with an occluded portal vein and was unsatisfactory in two others, in one because she was moribund and in the other because the hepatic artery had been ligated. Dramatic improvement in symptoms occurred in the nine patients in whom embolisation was successfully carried out, with abolition of flushing, severe abdominal pain, and wheeze and reduction in diarrhoea from 10.5 (SD 7.6) to 1.6 (0.9) stools/day. Urinary excretion of 5-hydroxyindole acetic acid fell from 1048 (716) to 289 (184) mumol/24 h (200 (137) to 55 (35) mg/24 h). Complications included one death from septicaemia, a hepatic abscess requiring surgical drainage, abdominal pain in three patients, pleural effusion in two, and transient encephalopathy in one. Relief of symptoms lasted for one to 24 months, and second embolisation in two patients produced further remissions of four to six months. Five patients died, one to 40 months after embolisation, in four cases because of metastases or heart failure. Hepatic embolisation is the treatment of choice for symptoms of the carcinoid syndrome resistant to medical treatment.     

The incidence of skin manifestations by dermatophytes in patients with psoriasis

Thirty-four psoriatic patients (23 males, 11 females) were found to have skin manifestations of dermatophyte infection. Tinea pedis was observed in 20 cases, tinea cruris in 6 and tinea mannum in 2. T. rubrum was the causative agent in all of these with the exception of 2 cases caused by E. floccosum. Lesions of tinea corporis were found intermingled with psoriatic plaques in various areas of the body skin in 6 patients (4 males, 2 females); T. rubrum was isolated from 5 of these and M. canis from one. Twenty-one of these psoriatic patients also had lesions caused by C. albicans in the toe-webs and interdigital aspects of the fingers, the latter being associated with paronychia in 9 cases. These findings indicate that we should remain aware of the possibility of fungus manifestations in patients with psoriasis, which would not appear to be an exceptional occurrence.     

Haemodialysis and transplantation in Wegener's granulomatosis.

Two men with Wegener''s disease began immunosuppressive treatment during severe renal insufficiency. Despite an initial temporary remission new lesions appeared and renal failure progressed. Haemodialysis was started, cytotoxic drugs were stopped, and steroid dosage was reduced. All extrarenal manifestations of the disease remitted, however, suggesting a favourable effect of either the immunosuppression induced by terminal renal failure or the haemodialysis itself. Renal transplantation was then undertaken in both patients. Thirteen and 55 months after the operations respectively renal function was satisfactory and no signs of reactivation of Wegener''s disease had appeared. These results show that whatever the activity of Wegener''s disease and its initial response to immunosuppressive agents, dialysis and transplantation are fully warranted once irreversible renal failure is established.     

Hypermétabolismes médullaires en TEP au 18F-FDG chez les patients atteints de cancer : signification et comparaison à l’IRM médullaire

Diffuse bone marrow uptake of ¹⁸F-FDG-PET in cancer patients raises the problem of differential diagnosis between marrow involvement and stimulated marrow. In this study, we prospectively included, during a 1-year period, all cancer patients referred for initial staging showing an unexplained diffuse bone marrow uptake and explored consecutively by MRI. The abnormalities described on PET and the conclusion reached about disease status of bone marrow (“benign” or “malignant”) were compared with corresponding MRI results, as well as clinical and biological findings pertinent when bone marrow activity is studied, marrow status considered by referring clinicians, and follow-up data. During 1 year, 60 patients had diffuse bone marrow uptake on ¹⁸F-FDG-PET, 26 underwent MRI examination and were finally included in the study. Results of PET and MRI were concordant in 24 cases (six “malignant” and 18 “benign”) and two cases were discordant, judged “malignant” by MRI and “benign”by PET. The outcome after confrontation of MRI and PET, was “malignant”for one patient and “benign” for the other one. The final results, was “malignant” for seven patients and “benign” for 19 patients and this final diagnosis was retained by referring clinicians. Among the 19 patients with diffuse bone marrow uptake considered as benign, seven patients had a pejorative evolution and four of them developed osteomedullary metastases. In cancer patients, ¹⁸F-FDG-PET identify bone marrow diffuse uptake which seems to correspond well to abnormalities assessed on MRI studies. Notably, heterogenous 18F-FDG uptake and/or foci of increased uptake seems significative of marrow involvement. The limited population size and discordant published findings about bone marrow evaluation by ¹⁸F-FDG-PET compared with MRI can not permit to ensure that these imaging modalities or one of these are sufficient to assess bone marrow status without performing bone marrow biopsy. Some patients with unexplained diffuse bone marrow uptake develop disease progression, such observations could be interestingly assessed by further studies.

Haematologic changes in gastritic cancer

Haematologic disturbances in 13 cases of gastric cancer are described. All the patients had anemia of different origin. Increased leukocytosis was observed in half of the cases, leukaemia reaction in one third. Haemolysis was present in 50% of cases. Thrombocytopenia coexisted most frequently with disseminated intravascular coagulation in 4 patients. Bone metastases were visualised as osteolytic foci with radiological methods or increased capture of isotopic marker in the bones under scintigraphic examination. Under the microscope neoplastic metastases were found in bone marrow smears of 5 patients. All patients displayed symptoms of gastric ulcer disease acute or chronic phase. In some cases only repeated gastroscopic examination and mucosa biopsy was the only way to confirm cancer. In other cases the diagnosis was made after the histopathologic examination of the resected stomach, in still others by a section.     

Radioisotopic Bone Scintigraphy with the Gamma Camera in the Investigation of Prostatic Cancer

Experience with x-rays, strontium-87m scintigraphy, and technetium-99m polyphosphate scintigraphy in the identification of bone metastases in 201 patients with prostatic cancer is reviewed. About 40% of the patients had demonstrable metastases in bone at the time of first presentation.Comparative studies of 247 x-ray and ^87mSr surveys indicated that x-rays failed to detect metastases in 10% of cases where they were identified by ^87mSr but that the isotopic survey similarly failed to detect radiologically evident deposits in 7% of cases.Similar studies comparing ^99mTc polyphosphate surveys with x-ray scans showed that x-rays missed isotopically detected metastases in 12% of cases, but in only one survey out of 67 did the isotope miss radiologically evident deposits. In a series of 32 patients investigated by both isotopic techniques ^99mTc polyphosphate did not fail to detect any metastases and identified deposits in one patient in whom they were missed by ^87mSr scintigraphy. About 15% of both x-ray and ^87mSr surveys gave equivocal results, but only 3% (2 out of 67) of ^99mTc polyphosphate surveys were equivocal.We concluded that ^99mTc polyphosphate bone scintigraphy with the gamma camera was the most reliable of the techniques used for the identification of bone metastases in patients with carcinoma of the prostate. The results of scintigraphy with ^87mSr suggested that serial surveys may provide early evidence of hormone resistance in prostatic cancer.     

Relationship of CA 125 and CA 19.9 with lung carcinoma histological subtype: preliminary study

The aim of this work was to study the possible utility of simultaneous determination of CA 125 and CA 19.9 in patients with lung cancer. Serum levels of both markers were studied in 87 patients without metastases (Mo), 72 patients with distant metastases (MT) and 15 cases without clinical evidence of disease after primary treatment (NED). Sixty-five tumors were epidermoid, 34 were adenocarcinomas, 24 were cell undifferentiated carcinomas and 51 were small-cell carcinomas. Sera from 75 healthy subjects and 20 patients with benign lung disease were used as controls. The cut-off values used were 35 and 37 U/ml for CA 125 and CA 19.9, respectively. CA 125 and CA 19.9 serum levels were within normal limits in all control patients. In NED patients these markers were not elevated, except in one with chronic liver disease who showed elevated CA 19.9 (76 U/ml). Twenty-five percent of Mo lung cancer patients and 40.3% of MT cases had CA 19.9 over 37 U/ml. Abnormally high levels of CA 125 were found in 18.7% and 22.9% of Mo and MT patients, respectively. Sixty percent of patients with large cell undifferentiated carcinoma had elevated CA 125 (mean 176 U/ml) compared to 15.4% of patients with all other histological types of tumors combined (54.3 U/ml, p less than 0.01). CA 19.9 serum levels were also more often elevated in patients with large cell undifferentiated carcinomas (50%, 7/14 cases) than in other histological types (30%, 36/120 patients), but the difference was not statistically significant.(ABSTRACT TRUNCATED AT 250 WORDS)     

Symptomatic infections by toscana virus in the Modena province in the triennium 1999-2001

We report nine cases of clinical manifestations by Toscana virus (TOSV) diagnosed at the Centre for the Diagnosis of Viral Diseases of the University of Modena and Reggio Emilia, in the inhabitants of Modena province (Emilia Romagna region), in the triennium 1999-2001. TOSV was involved in six cases of meningitis, two of meningoencephalitis and one case of febrile erythema without meningeal manifestations. Six TOSV-infected patients had stayed for a few days in a different area of the Tuscany region before the onset of clinical manifestations so, only three cases of infections by TOSV had an autochthonous origin.     

Treatment of diabetic patients; observations on the use of carbutamide and tolbutamide

Of a group of 32 patients with diabetes, 26 had a favorable modification of the disease in response to administration of butyl-sulfonyl-urea. All but one of the patients who had good response were past the age of 38. All diabetic patients included in this group were those with little or no tendency to ketosis after cessation of insulin administration. No toxic manifestations were noted except for a slight decrease in leukocytes in one case.
