RESUMO

AIM: The objective of this study is to present the history of cancers of the external genital organs of male in Hérault using data from the Hérault tumor register (RTH) over a period of 30 years. PATIENTS AND METHODS: Using the RTH database, we studied the development of testicular germ cell tumors (TGCT) and penile cancer (PC) over 30 years, from 1987 to 2016. We analyzed the incidence and mortality data for these tumors. We compared these results to French, European and global data. RESULTS: In 30 years of registration we have recorded 725 cases of TGCT and 175 cases of PC. The age standardized incidence rate (ASR) of TGCT has doubled between 1987 and 2016 (4.2 per 100,000 in 1987 and 9.3 per 100,000 in 2016). It was multiplied by 2.63 in the population of patients aged 30 to 44. There is a decrease of the mortality rate with a ASR of 0.8 deaths per 100,000 in 1987, and 0.4/100 000 in 2016. The PC incidence ASR was stable between 1987 and 2016 (0.4-0.9/100,000). Mortality is stable with a ASR between 0.1 and 0.3 deaths per 100,000 between 1987 and 2016. CONCLUSION: The incidence of TGCT has increased sharply in the Hérault over the past 30 years, while a decrease in mortality has been observed. The proportion of seminomas is increasing; it has gone from 53 % to 60 % in 30 years in the Hérault. The incidence and mortality of PC shows a stability in the Hérault over the past 30 years.

RESUMO

OBJECTIVE: The objective of the study was to determine the specificities of renal cell carcinoma (RCC) in the department of Herault using the Herault Tumor Registry over 30 years. METHODS: Data of this study were obtained from the Herault cancer database. We analysed the evolution of RCC from 1987 to 2016, including the incidence, mortality, cancer pathology and staging at the moment of diagnosis. We compared our results with national and international data. RESULTS: We identified 3769 newly diagnosed RCC: 2628 in men (69,7%) and 1141 in women (30,3%). In 2016, RCC was the 8th most frequent cancer, both genders combined, the 7th most frequent cancer in men and the 11th in women. New cases of RCC increased by 4.2 in men and 3.3 in women over the study period. The number of localised forms increased by 9% over 20 years. In 2016, the probability of having a RCC before the age of 75 was of 2.11% for a man and of 0.62% for a woman. CONCLUSION: Over 30 years, the incidence rate of RCC increased in the department of Herault; however, mortality decreased over the same period. This analytical data should be improved by the development of the Registry of Herault Specialised in Onco-Urology (RHESOU). LEVEL OF EVIDENCE: 3.

RESUMO

PURPOSE: In 2016, the Herault tumor registry collected 1961cancers in urology (21.4 % from all Herault cancers this year). RHESOU was created to complete RTH' data with specific parameters in onco-urology. The aim of this study is to describe RHESOU and to give some examples with our first results. MATERIAL AND METHODS: In November 2018, RHESOU (Registry HErault Specialised in Onco-Urology) was founded with the same registry recommendations. It collects specific oncologic parameters and also complete RTH's data. For each urological cancer, a specific survey with different choices was performed to collect a maximum of data which could be present in patients' file. These surveys were used for urological cancers cases that live in Herault in 2017. RESULTS: In 2017, we collected 970 prostate cancers, 581 bladder cancers, 212 kidney cancers, 51 upper excretory tract cancers, 28 testicle cancers and 9 penil cancers. Our urological data collection gives many possibilities to create many requests for detailed analysis in urological cancers. In this article, we reported data from kidney, bladder and prostate cancers. CONCLUSIONS: RHESOU is a new tool opened to the different urologic corporations (urologists, pathologists, oncologists, radiotherapists, radiologists) that permits an overview in urological cancers in Herault. Finally, one important aim is that this tool will be adapted when new treatments or new important parameters appear in the years ahead. LEVEL OF EVIDENCE: 3.

RESUMO

BACKGROUND AND PURPOSE: Whether to withhold mechanical thrombectomy when the diffusion-weighted imaging (DWI) lesion exceeds a given volume is undetermined. Our aim was to identify markers that will help to select patients with large DWI lesions [DWI-Alberta Stroke Program Early Computed Tomography Score (DWI-ASPECTS) ≤ 5] that may benefit from thrombectomy. METHODS: From May 2010 to November 2016, 82 acute ischaemic stroke patients with DWI-ASPECTS ≤5 (43 men, 64.6 ± 14.4 years, National Institutes of Health Stroke Scale 18.4 ± 5.4) treated with state-of-the-art mechanical thrombectomy were studied. Thrombectomy alone was performed in 28 (34%) and bridging therapy in 54 (66%) patients. Recanalization was defined as a thrombolysis in cerebral infarction score 2B-3 and significant hemorrhagic transformation as parenchymal haematoma type 2 (European Cooperative Acute Stroke Study 3 classification). Pretreatment variables were compared between patients with a good (modified Rankin Scale 0-2) and a poor (modified Rankin Scale 3-6) neurological outcome at 3 months. RESULTS: Overall, 28 patients (34%) achieved good neurological outcome at 3 months. Recanalizers were significantly more likely to achieve good outcome (61% vs. 7.3%, P < 0.0001), had lower mortality (24% vs. 49%, P = 0.03) and similar rates of parenchymal haematoma type 2 (9.8% vs. 7.3%, P = 1) compared to non-recanalizers. Regression modelling identified DWI-ASPECTS >2 [odds ratio (OR) 6.93; 95% confidence interval (CI) 1.05-45.76, P = 0.04), glycaemia ≤6.8 mmol/l (OR 4.05; 95% CI 1.09-15.0, P = 0.03) and thrombolysis (OR 3.67; 95% CI 1.04-12.9, P = 0.04) as independent predictors of good neurological outcome. CONCLUSIONS: In patients with DWI-ASPECTS ≤5, two-thirds of patients experienced good neurological outcome when recanalized by state-of-the-art thrombectomy, whilst only one in 14 non-recanalizers achieved similar outcomes. Pretreatment markers of good neurological outcomes were DWI-ASPECTS >2, intravenous thrombolysis and glycaemia ≤6.8 mmol/l.

RESUMO

BACKGROUND AND PURPOSE: The susceptibility vessel sign (SVS) on T2*-weighted magnetic resonance imaging has been reported in several studies as a negative predictor of early recanalization after intravenous thrombolysis. The meaning of SVS regarding the results of mechanical thrombectomy with stent retrievers was investigated. METHODS: Susceptibility vessel sign presence and length were studied in 153 acute ischaemic stroke patients (82 men; mean ± SD age 59 ± 17 years, baseline National Institutes of Health Stroke Scale score 17.2 ± 6.5) from three stroke centres, treated with either mechanical thrombectomy alone (n = 84) or bridging therapy (n = 69). Variables were compared between recanalizers, defined as thrombolysis in cerebral infarction (TICI) scores ≥2b, and non-recanalizers (TICI<2b). RESULTS: The SVS was present in 113 (73.8%) patients. There was no association between the presence of SVS and recanalization, obtained in 86 (56.2%) patients, in the whole population [odds ratio (OR) 1.24, 95% confidence interval (CI) 0.53-2.92, P = 0.84) and in treatment subgroups (bridging: OR = 0.91, 95% CI 0.29-2.87, P = 1.0; thrombectomy alone: OR = 1.85, 95% CI 0.48-7.16, P = 0.54). However, in SVS+ patients, recanalization decreased with SVS length (OR 0.94 for each additional mm, 95% CI 0.89-0.99; P = 0.02). CONCLUSIONS: The success of recanalization in acute stroke patients treated with stent retrievers was related to thrombus length but not to the presence of SVS.

RESUMO

INTRODUCTION: Behçet's disease is a multi-system vascular-inflammatory disease with possible involvement of the central nervous system. Lesions of the corpus callosum on MRI have been rarely reported in this disease. CASE REPORT: A 47-year-old woman was admitted for a sudden right hemiplegia and confusion revealing a Behcet's disease. MRI showed a pedonculo-thalamic lesion and a white matter hypersignals, which was suggestive of the disease. Besides, involvement of the corpus callosum was observed. CONCLUSION: This case demonstrates that Behcet's disease should be considered among diseases with corpus callosum involvement.

RESUMO

INTRODUCTION: When a patient treated by immune checkpoint inhibitors for metastatic melanoma presents with pulmonary symptoms, several diagnoses are possible. We report a case of acute granulomatous lung disease secondary to repeated kayexalate inhalations, and probably stimulated by immunotherapy. CASE REPORT: A patient treated with pembrolizumab and then ipilimumab presented with fever and acute shortness of breath. His pulmonary symptoms got progressively worse, leading to an acute respiratory distress syndrome. Chest CT displayed a pattern of non-specific organized pneumonia. Pulmonary infection, tumor progression, specific immune-related lung toxicity and immunotherapy-induced sarcoidosis were discussed. Histopathological examination of a lung biopsy showed a foreign body granulomatous macrophage reaction associated with crystalline, basophilic, purple and laminated elements, evoking kayexalate particles. These elements helped rewrite the diagnosis and confirmed a kayexalate-induced granulomatous lung disease secondary to repeated aspiration. The patient's respiratory condition got better following discontinuation of kayexalate together with systemic corticosteroids. Symptoms relapsed with resumption of the immunotherapy but were controlled with the addition of a new course of prolonged systemic corticosteroid therapy. We can hypothesize that immunotherapy played a role in the recurrence of the granulomatous lung reaction, or that there was an association between an aspiration pneumonia and an immunotherapy-induced lung toxicity. CONCLUSION: Facing respiratory symptoms during immunotherapy, the treatment may be the cause, but lung biopsy should be performed rapidly to arrive to a certain diagnosis.

RESUMO

We report the cases of two patients admitted to the Emergency Department with a clinical picture of right heart failure. An emergency echocardiograph suggested an intra-cardiac tumor which turned out to be a primary intra-cardiac lymphoma in one case, and a diffuse lymphoma principally localised in the heart in the other. Echocardiographic, CT and MRI investigations clarified the sites, as well as anatomical relations and extensions. Histology confirmed the diagnosis, and allowed classification of the lymphoma in order to decide on treatment. A PET scan performed in one patient illustrated the response to treatment. The respective significance of each of these investigations is discussed, in addition to the management. While transthoracic echocardiography remains the key element in the acute management, MRI and PET scans are being used more and more often for determining the character of these lesions, as well as for assisting with therapeutic decisions and for follow-up.

RESUMO

Expression of a proliferating antigen by KI-67 immunohistochemistry was analyzed with a SAMBA 2005 computer-assisted image processor (Traitement de l'Information for des Techniques Nouvelles, Grenoble, France) in 47 surgically resected bronchopulmonary carcinoids embedded in paraffin. The clinicopathologic characteristics and KI-67 labeling, expressed in percentage of stained nuclear surface relative to the total nuclear surface, of 31 typical carcinoids and 16 atypical carcinoids were compared and assessed with respect to patient survival. The proliferation status was significantly higher in histologically atypical than in typical carcinoids. Moreover, using a 4% cutoff, we observed a significant difference for the 4-year overall survival rate. Semiquantitative analysis of the proliferation index by KI-67 immunostaining seemed to be an effective means of identifying high risk subsets among patients with histologically atypical carcinoids and for whom adjuvant chemotherapy could be proposed.

RESUMO

BACKGROUND: Allograft coronary artery disease (CAD) is a major long-term complication in heart transplanted patients. However, the metabolic basis of allograft CAD remains to be fully elucidated. We analyzed the lactate dehydrogenase heart (H) and muscle (M) isoenzyme pattern in endomyocardial biopsy specimens and the evolution of the H/M ratio to test whether changes in this ratio could be the earliest manifestation of allograft CAD. METHODS: Twenty-four heart transplant recipients were followed up for 12 months. Endomyocardial biopsy was performed at 1, 2, 3, 6, and 12 months after transplantation. Lactate dehydrogenase 1 through 5 isoenzymes were separated by electrophoresis, and the H/M ratio was calculated. Two groups of patients were identified: group 1 (n = 20), patients without allograft CAD; and group 2 (n = 4), patients with poor outcome (three deaths, 1 case of low cardiac output) and angiographic and histologic evidence of allograft CAD. RESULTS: Both groups had similar H/M baseline values. The H/M ratio was higher (p = 0.01) in group 1 at 6 months (3.48 +/- 0.64 versus 2.17 +/- 0.43) and 12 months (3.76 +/- 0.92 versus 2.18 +/- 0.45) when compared with group 2. The H/M ratio increased from 2.78 +/- 0.89 at 1 month to 3.76 +/- 0.92 at 12 months (p = 0.02) in group 1 and decreased in group 2 (2.86 +/- 0.49 versus 2.18 +/- 0.45; not significant). CONCLUSIONS: Changes in H/M ratio reflect an anaerobic shift in the lactate dehydrogenase isoenzyme composition and can be taken as an early indicator of allograft CAD.

RESUMO

Primary agammaglobulinemia is a rare disorder which is associated with articular symptoms in 11% of patients. Septic arthritis may occur, but often patients complain of chronic oligoarthritis and have a clinical presentation similar to rheumatoid arthritis. We report 2 cases of primary agammaglobulinemia in adults, associated with non-erosive chronic arthritis. Peripheral blood lymphocyte phenotyping showed a predominance of CD8 lymphocytes with a CD4/CD8 ratio < 1. We did not find any abnormalities in cellular immunity. A histological study of the synovium showed chronic synovitis with perivascular CD8 lymphocyte infiltrates. Intravenous infusion of immunoglobulins resulted in a dramatic improvement in the arthritis in both cases. In one patient we noticed a decrease in CD8 lymphocytosis. These results suggest that CD8 lymphocytes are involved in the pathogenesis of the arthritis associated with agammaglobulinemia.

RESUMO

The case of an 81-year-old woman with persistent post-traumatic pain of the knee linked to tophaceous gout of the patella is presented. This gout was associated with adenomatous primary hyperparathyroidism. The relationship between hyperuricemia, hyperparathyroidism and chronic renal failure is discussed.

RESUMO

We report the first case of choriocarcinoma occurring during the course of systemic lupus erythematosus (SLE). This choriocarcinoma was revealed by pulmonary metastasis associated with pulmonary hypertension secondary to neoplastic thrombi and pulmonary embolism, in parallel to a flare up of the SLE. The role of hormones in SLE is discussed.

RESUMO

Erythrocyte deformability and aggregability, fibrinogen plasma level, and hematocrit were measured in patients with primary open-angle glaucoma and in age-matched control subjects. Only one parameter, red blood cell rigidity, as evaluated by the Hanss filtration technique, was found significantly elevated in glaucoma patients. This erythrocyte abnormality, which corroborates previous data on blood viscosity, could be an important factor in the pathogenesis of optic nerve damage and could support the hypothesis of a primary oxidative stress in glaucoma.

RESUMO

Transplant-related coronary artery disease is the main cause of death in orthotopic heart transplant recipients one year or more after operation. We report our own experience with chronic vascular rejection occurring 4, 10, and 15 months after transplantation in 3 of 71 consecutive patients. Immunosuppressive regimen included perioperative lymphocyte antibody therapy, cyclosporine, azathioprine and methylprednisolone. All 3 patients received cardiac allografts from donors not the same ABO blood type and developed cytomegalovirus infection (one primary phase infection and two reactivations). Death occurred in all of them. Histologic signs of both cellular and vascular rejection were found in one patient and two had pure vascular rejection. These observations support the potential role of cytomegalovirus infection and donor-recipient partial ABO blood type group incompatibility in the development of allograft vasculopathy as a short-term complication in heart transplant recipients.

RESUMO

About 15% of patients with cancer have cerebrovascular lesions, resulting from 4 kinds of disorders sometimes intermingled in advanced disseminated cancer: coagulation disorders, direct effects of the tumor, infections and therapeutic measures. Infarction, hardly less frequent than hemorrhage, mostly complicates lymphoma and carcinoma. Hypercoagulation states, such as chronic disseminated intravascular coagulation, nonbacterial thrombotic endocarditis, and nonmetastatic cerebral venous thrombosis account for about 50% of cases. Tumor emboli, as seen in intravascular malignant lymphomatosis, arteritis related to aspergillus, granulomatous angiitis with or without herpes zoster and radiation-induced atherosclerosis are rarer. Cerebral hemorrhages, excluding bleeding from the metastases of choriocarcinoma and melanoma are mainly associated with leukemia by acute disseminated intravascular coagulation as in promyelocytic leukemia, by leukostasis or by pancytopenia. Both infarction and hemorrhage rarely reveal the neoplasia. Lesions are often small and disseminated, and therefore produce a picture of diffuse acute or subacute encephalopathy rather than acute focal deficits. Finally, there may be no relationship between the cerebrovascular event and the neoplasia, and atherosclerosis or traumatic subdural hematoma may well be the causal factor.

RESUMO

We report a case concerning a 65 year old man who suffered from a drug resistant asthma and radiographically visible mass in the right lower lobe of the lung. Pathological studies demonstrated it to be "Bronchopathia Osteoplastica", involving segmental bronchi, with completed hematopoietic metaplasia. This rare dystrophic lesion was associated with localized lambda light chain amyloidosis as was proved by the immunohistochemistry. This association suggests a possible relation between amyloidosis and abnormal osteogenesis.

RESUMO

Amyloidosis of the genito-urinary tract is uncommon. We report 8 cases, often misdiagnosed as a neoplastic process (6/8). Amyloidosis was localized in the bladder (3 cases), in the ureter (1 case) and in the prostate and/or seminal vesicles (4 cases). The amyloid protein was characterized in 7 cases by immunohistochemistry. Among the bladder and ureter amyloidosis, 2 cases were classified as AL lambda amyloidosis and one case as AA amyloidosis in a patient with long history of chronic arthritis. In the fourth case, the deposits could not be identified. Nevertheless an AL amyloidosis might be suggested. Two cases of prostate and/or seminal vesicles amyloidosis were stained with an anti-B2M antibody, in hemodialyzed patients. The 2 others, positive with the anti-Transthyretina antibody, were classified as senile amyloidosis. This small series illustrated the heterogeneous pathogenic types of amyloidosis in the urogenital tract and emphasized the interest of immunohistochemistry to identify the chemical composition of these deposits.

RESUMO

Small cell neuroendocrine carcinomas are frequent in the bronchial tree, but are very are in the gastrointestinal tract. A 51-year-old woman underwent total esophagectomy for an ulcerated tumor of the lower third of esophagus. Pathologic examination showed an infiltrating small cell carcinoma, and immunohistochemical analysis proved it to be neuroendocrine. The patient died 2 months later from respiratory failure related to pleuritic metastases. Review of the 162 previously published cases showed a mean survival of 6.2 months, and rapid dissemination of metastatic disease, as in our case. As for small cell bronchial carcinoma, systemic chemotherapy should be considered for neuroendocrine carcinoma of the esophagus.

RESUMO

Breast carcinomas with false negative mammogram correspond to carcinomas diagnosed with means other than mammogram when the mammogram, at the time of diagnosis, showed no significant abnormality. The rate of false mammogram is difficult to ascertain because few studies have been published on this subject. The absence of mammographic abnormality is related to histopathological characteristics of the tumor and mammographic features of the patient's breast tissue. The small size of the tumor, the lack of microcalcifications often due to tumor necrosis and the absence of any significant associated desmoplastic reaction are the main histopathological factors encountered, particularly for dense breasts.
