RESUMO
BACKGROUND: The diagnosis of cancer is strongly associated with the risk of mental disorders even in patients with no previous history of mental disorders. Accumulating data suggest that mental distress may accelerate tumor progression. We hypothesized therefore that mental disorders after a cancer diagnosis may increase the risk of cancer-specific mortality. PATIENTS AND METHODS: We conducted a nationwide cohort study including 244 261 cancer patients diagnosed in Sweden during 2004-2009 and followed them through 2010. Through the Swedish Patient Register, we obtained clinical diagnoses of all mental disorders and focused on mood-, anxiety-, and substance abuse disorders (ICD10: F10-F16, F18-F19, F32-F33, F40-F41, and F43-45) that are commonly diagnosed among patients with cancer. We further classified the studied mental disorders into first-onset or recurrent mental disorders. We used Cox regression to estimate multivariable hazard ratios (HRs) with 95% confidence intervals (CIs) as a measure of the association between mental disorders after cancer diagnosis and cancer-specific mortality, adjusting for age, sex, calendar period, educational level, cancer stage, and cancer type at diagnosis. RESULTS: After cancer diagnosis, 11 457 patients were diagnosed with mood-, anxiety-, and substance abuse disorders; of which 7236 were first-onset mental disorders. Patients with a first-onset mental disorder were at increased risk of cancer-specific mortality (HR: 1.82, 95% CI: 1.71-1.92) while patients with a recurrent mental disorder had much lower risk elevation (HR: 1.14, 95% CI: 1.05-1.24). The increased cancer-specific mortality by first-onset mental disorders was observed for almost all cancer sites/groups and the association was stronger for localized cancers (HR: 2.00, 95% CI: 1.73-2.31) than for advanced cancers (HR: 1.49, 95% CI: 1.32-1.69). CONCLUSIONS: Patients with a first-onset common mood-, anxiety-, or substance abuse disorder after cancer diagnosis may be at increased risk of cancer-specific death.

The primary pulmonary lymphoma is a rare disease, representing 0.5 to 1% of the malignant lung tumors. In our countries, in spite of the increasing prevalence of the pulmonary tumors, aggravated by smoking and environmental factors, any case report of the primary pulmonary lymphoma is notified. We report a confirmed case of MALT lung lymphoma that is managed in our hospital. Mr. S.B., 68-year-old man, not smoking, without particular professional exhibition, is admitted for a chronic cough with blood-streaked sputum, dyspnea, chest pain and loss of weight. His symptomatology is evolving for 4months. In the examination, the general health was passable and he presented a pulmonary condensation syndrome at right. The physical examination of others systems was normal. There was a biological inflammatory syndrome. The bacteriological examinations of the bronchial expectorations were negative. The chest CT showed bilateral alveolar opacities at the upper, with attraction of the fissures, without nodes. The bronchoscopy showed anomalies of the bronchial mucous membrane in 2 superior lobes. The perendoscopiques biopsies confirmed a MALT lung lymphoma. We did not find other localizations. Chemotherapy was proposed to our patient with favorable evolution. The MALT primary lung lymphoma must not be underestimated. Clinical manifestations and radiological characteristics are no specific and it's necessary to eliminate a lung cancer or tuberculosis in our countries. The difficulties of their diagnostic are intensified by the not availability of an adequate technical tray.

BACKGROUND: Data are scarce on the potential change in suicidal behavior among adolescents and young adults after receiving a cancer diagnosis. PATIENTS AND METHODS: We conducted a population-based cohort study including 7 860 629 Swedes at the age of ≥15 during 1987-2009. Among the cohort participants, 12 669 received a first diagnosis of primary cancer between the age of 15 and 30. We measured the relative risks (RRs) of suicidal behavior (defined as completed suicides or suicide attempts) after cancer diagnosis. We also carried out a case-crossover study nested within the cohort to adjust for unmeasured confounders. RESULTS: Twenty-two completed suicides (versus 14 expected) and 136 suicide attempts (versus 80 expected) were identified among the cancer patients. The RR of suicidal behavior was 1.6 [95% confidence interval (CI), 1.4-1.9] after a cancer diagnosis, compared with cancer-free individuals. Risk increase was greatest immediately after diagnosis; the RR was 2.5 (95% CI 1.7-3.5) during the first year after diagnosis and was 1.5 (95% CI 1.2-1.8) thereafter. This pattern was similar for completed suicide and suicide attempts. The elevated risks were evident for majority of the main cancer types, except for cancer in thyroid, testis and melanoma. The case-crossover analysis of suicidal behavior during the first year after cancer diagnosis revealed similar results. CONCLUSIONS: Adolescents and young adults receiving a cancer diagnosis are at substantially increased risk of suicidal behavior, particularly during the first year after diagnosis. Although the absolute excess risk is modest, these findings emphasize the need to support and carefully monitor this vulnerable population.

BACKGROUND: Prostate cancer (PC) is a leading cause of fatal cancer in men in developed countries. Coeliac disease (CD) has previously been linked to a raised cancer risk, and changes in some exposures following a CD diagnosis might hypothetically raise PC risk. METHODS: We identified 10,995 patients with CD who had undergone a small intestinal biopsy in 1969-2007. Statistics Sweden then identified 54,233 age-matched male reference individuals from the general population. PC data were obtained from the Swedish Cancer Register. Hazard ratios (HRs) for PC were estimated using Cox regression analysis. RESULTS: During follow-up, 185 individuals with CD (expected n=200) had an incident diagnosis of PC. This corresponds to a HR of 0.92 (0.79-1.08) (with 95% confidence interval) and an absolute risk reduction of 15/100,000 person-years among those with CD. An increased risk was not observed even when identification of PC began 5 years after biopsy. CONCLUSION: Our conclusion is that a CD diagnosis does not represent an increased risk for PC.

To implement a second-generation HIV surveillance, through a prevention programme of HIV and sexually transmitted infections (STIs), Senegal conducted a combined survey from 2003 September 2 to October 5 in Malicounda located in the region of Thiès in the center of Senegal. The objectives of this study were to collect data on sexual behaviours and prevalence of HIV gonorrhoea, Chlamydia infections and syphilis in the community. After obtaining their informed consent, 679 people were interviewed among whom 617 accepted blood sampling and 619 accepted urine sampling, that is to say an acceptance rate of 90% and 91% respectively. Women reported having fewer sexual risk behaviours than men. However, when having sexual risk behaviour men only reported using condoms. Overall, the prevalence of HIV as well as the prevalence of STI are low: 0.5% for HIV, 0.9% for syphilis, 0.3% for Chlamydia trachomatis and 0.2% for Neisseria gonorrhoea. In this study, the small numbers of cases of infection identified did not allow to analyse the influence of sexual behaviour at risk on the occurrence of these infections.

In a national register-based study of incidence trends and mortality of incidental prostate cancer in Sweden, we found that a significant proportion (26.6%) of affected men diagnosed died of their disease, which challenges earlier descriptions of incidental prostate cancer as a non-lethal disease.

OBJECTIVE: Insulin receptor substrate-1 (IRS-1) acts as a docking protein between the insulin-like growth factor-1 (IGF-1) receptor and intracellular signaling molecules in the IGF-1 signaling pathway. Accumulating data support a role of IGF-1 in prostate carcinogenesis. We assessed the influence of the most common IRS-1 gene polymorphism (Gly972Arg) on prostate cancer risk, alone and in combination with IGF-1 and other components in the IGF-1 signaling pathway. MATERIALS AND METHODS: In a nested case-control study within the Physicians' Health Study, the IRS-1 polymorphism was assayed from prospectively collected samples from 564 incident prostate cancer cases and 758 controls matched on age and smoking. We calculated relative risks (RR) and 95% confidence intervals (CI) using conditional logistic regression. RESULTS: Among the controls, 0.8% were homozygous (AA) and 12% were heterozygous (GA) for the polymorphic allele. There was no association between carriage of the A allele and total prostate cancer risk (RR = 1.1 95% CI = 0.8-1.5), advanced disease (stage C or D or lethal prostate cancer, RR = 1.3 95% CI = 0.8-2.3), or plasma IGF-1 levels. We explored possible interactions with body mass index and components in the IGF-1 pathway including IGFBP3, PI3k, and PTEN but none of these factors influenced the relation between IRS-1 genotype and prostate cancer risk. CONCLUSIONS: Our data do not support an association between carriage of the variant IRS-1 gene and prostate cancer risk.

AIM: Pleural biopsy and adenosine deaminase activity are not available at our center and the treatment begins without substantiation diagnosis in patients with tuberculous pleural effusion (PE). METHODS: In order to evaluate the validity of an empiric antituberculous therapy in exsudative PE with high prevalence of lymphocytes, we conducted a retrospective study during 1 year. Patient was enrolled if no signs of tuberculous infection, pneumonia or cancer were present. RESULTS: During 1 year, 38 patients were enrolled (23 males, mean age=36 years). PE was major (> 2/3 of the lung) in 14 cases, moderate (between 1/3 and 2/3) In 18 cases and minor (<1/3) in 6 cases. Tuberculous contagion was observed in 10 patients. Tuberculinic test was positive in all patients (12-24 mm). Clinical and radiological cure was obtained in 37 cases, except 1 patient who died from acute heart failure. No recurrence of PE was observed after 1 year follow-up. CONCLUSION: In our endemic areas, empiric antituberculous treatment seems to be an effective strategy in patients with exsudative PE.

Anti-adhesion mucins have proven to play an important part in the biology of several types of cancer. Therefore, we test the hypothesis that altered expression of MUC-1 is associated with prostate cancer progression. We retrieved archival tumour tissue from a population-based cohort of 195 men with localised prostate cancer (T1a-b, Nx, M0) that has been followed for up to 20 years with watchful waiting. Semi-automated, quantitative immunohistochemistry was undertaken to evaluate MUC-1 expression. We modelled prostate cancer-specific death as a function of MUC-1 levels accounting for age, Gleason grade and tumour extent, and calculated age-adjusted and multivariate adjusted hazard ratios (HR). Men that had tumours with an MUC-intensity lower or higher than normal tissue had a higher risk of dying in prostate cancer, independent of tumour extent and Gleason score (HR 5.1 and 4.5, respectively). Adjustment for Gleason grade and tumour stage did not alter the results. Men with a Gleason score > or =7 and MUC-1 deviating from the normal had a 17 (RR=17.1 95% confidence interval=2.3-128) times higher risk to die in prostate cancer compared with men with Gleason score <7 and normal MUC-1 intensity. In summary, our data show that MUC-1 is an independent prognostic marker for prostate cancer death.

The identification of the TMPRSS2:ERG fusion in prostate cancer suggests that distinct molecular subtypes may define risk for disease progression. In surgical series, TMPRSS2:ERG fusion was identified in 50% of the tumors. Here, we report on a population-based cohort of men with localized prostate cancers followed by expectant (watchful waiting) therapy with 15% (17/111) TMPRSS2:ERG fusion. We identified a statistically significant association between TMPRSS2:ERG fusion and prostate cancer specific death (cumulative incidence ratio=2.7, P<0.01, 95% confidence interval=1.3-5.8). Quantitative reverse-transcription-polymerase chain reaction demonstrated high ets-related [corrected] gene (ERG) expression to be associated with TMPRSS2:ERG fusion (P<0.005). These data suggest that TMPRSS2:ERG fusion prostate cancers may have a more aggressive phenotype, possibly mediated through increased ERG expression.

In Africa the incidence of lung cancer is rising rapidly. The purpose of this prospective study was to analyze clinical, therapeutic, and prognostic features of lung cancer patients treated at the Principal Hospital in Dakar between 2002 and 2007. A total of 72 cases were compiled over the 5-year study period. In 88% of cases the patient was a male smoker with a mean age of 59.2 years. Histological samples were obtained in 79.1% of cases by bronchial fibroscopy (n=33), CT-guided transthoracic needle biopsy (n=17), or from a metastatic site (n=7). The histological diagnosis was squamous cell carcinoma in 23 cases, adenocarcinoma in 14, large-cell carcinoma in 17, small-cell lung cancer in 2, and bronchiolo-alveolar cancer in 1. Tumor staging demonstrated grades I-II in 6 cases, grade II in 17, and grade IV in 49. Symptomatic management was performed in 68% of patients. In the remaining cases management consisted of chemotherapy in 22 cases, radiotherapy for pain relief in 5, and surgery in 1. Ten patients were lost from follow-up. Median survival was 7 or 3 months depending on whether or not chemotherapy was performed. The much higher rate of histological diagnosis than in the sub-region is due mainly to the availability of trained personnel with access to bronchial endoscopy and CT-scan needle biopsy since September 2003. Administration of cytotoxins is feasible but the cost is excessive due to the lack of universal health care coverage: two-thirds of cases were abandoned whereas chemotherapy significantly improved median survival by 4 months (p < 0.0001). Prognosis of the disease is poor because management is undertaken at an advanced stage. Lung cancer is a health issue in Dakar, Senegal. It is urgent to develop therapeutic standards adapted to the African socio-economic setting as well as an anti-tobacco prevention policy.

BACKGROUND/AIMS: Helicobacter pylori infection is undoubtedly an important risk factor for gastric cancer. It remains unclear however whether antibiotic treatment may prevent gastric cancer development. Our aim was to assess long term gastric cancer risks in historic cohorts of patients presumed to have been heavily exposed to antibiotics. SUBJECTS: Using the Swedish Inpatient Register, we identified 501 757 individuals discharged with any one of 10 selected infectious disease diagnoses between 1970 and 2003. METHODS: We counted person time and non-cardia gastric cancer occurrences through linkage to virtually complete population and health care registers. Standardised incidence ratios (SIRs) were calculated for comparisons with cancer incidence rates of the general population in Sweden. RESULTS: No reduction in gastric cancer risk was observed in the infectious disease cohort in total (SIR 1.08 (95% confidence intervals 1.00-1.17) or for any of the presumed antibiotic regimens. There were no clear trends towards decreasing risk with time of follow up, but the risk tended to fall with increasing age at first hospitalisation for the infection (p<0.04). CONCLUSIONS: Our results do not confirm earlier observational findings of a reduced risk of gastric cancer following exposure to heavy antibiotic treatment among hip replacement patients. Suboptimal drug regimens, inadequate timing of H pylori eradication, or insufficient follow up time may possibly explain the lack of association in this setting. Although our findings do not rule out the cancer preventive potential of H pylori eradication, they emphasise that detection of such an effect, if any, may require considerable efforts.

We report the case of a 46-year-old man with an uneventful history who was hospitalized for suspected pulmonary embolism. The chest x-ray did not reveal any parenchymatous anomaly but disclosed pseudo-tumoral enlargement of the pulmonary arteries. There was no right ventricular overload at cardiac echography and the pulmonary arterial pressure was normal. Helicoidal angioscan demonstrated aneurismal dilatation of the both pulmonary arteries, complicated by a thrombus on the right. Outcome was favorable with anticoagulation. After ruling out acquired aneurysm, the diagnosis retained was idiopathic aneurysm of the pulmonary arteries.

HIV associated nephropathy syndrome ( HIVAN Syndrome ) is a recently identified entity and no study has been done in Senegal. So we report this observation. A 40 years old black patient was admitted for renal oedema syndrome and immunosuppressive signs. The biological investigations noticed a non-pur nephrotic syndrome and severe renal failure. Ultrasonography showed quite normal kidney sizes with hyper echogenicity and dediferenciation. HIV research was positive with 45 CD4 lymphocytes / mm3. This patient had no known causes of nephrotic syndrome ( diabetis, lupus ,amyloidosis.). So the diagnosis of HIVAN syndrome was determined with the clinical features and the bad outcome. We emphasize on the necessity to think about HIVAN in every black patient presenting a quickly progressive non-pur nephrotic syndrome. We expect prospectives studies to describe the clinical signs and the frequency of HIVAN syndrome in Senegal.

We report a case of DRESS syndrome also called drug hypersensitivity reaction occurring a 47 years old Senegalese man who has been taking allopurinol for 3 months. That drug was prescribed for peripheric arthralgias associated to a hyperuricemia. He presented a generalised pruritus, cutaneous lesions, fever and facial oedema. On the biological examens, hyperleucocytosis with hypereosinophilia and hyperlymphocytosis associated to the presence of segmented basophiles. In addition, a hepatic cytolysis and cholestasis were documented. Liver ultrasound was normal. The hemocults were negative. These following serologies have been performed and were negative: hepatitis B and C, Epstein Barr-virus, cytomegalovirus, syphilis, toxoplasma and parvovirus B19. The anti-nuclear and anti-DNA antibodies were negative. A favourable clinical evolution was remarked after allopurinol treatment withdrawal. A desquamation occurred after 6 days and hemogram turned out to the normal as well as the hepatic tests after 2 weeks. The virologic examens performed 2 months later were unremarkable. This case point out the importance of the early diagnosis and quick withdrawal of the drug in order to prevent serious forms leading to the 10% of death.

The adult T-cells lymphoma-leukemia is a serious complication by the HTLV-1 infection. It is a rarely described diseases in Africa, in spite of the frequency of the infection by this virus. We report two clinical observations of lymphomatous forms. The first observation concerned a 43 year old Senegalese woman, admitted for a deep alteration of her general status and peripheral polyadenopathies. The adenopathy biopsy set up the diagnosis of pleiomorph T lymphoma with great and medium cells. The HTLV-1 serology was positive. She had benefited of six polychemotherapy cures (cyclophosphamide, farmarubicine, oncovin, prednisone) within which she died in a cachectic presentation. The second observation concerned a 44 year old Senegalese man, admitted for peripheral polyadenopathies, ulcerated lesions of sole of the foot, and deep alteration of the general status. He presented a moderate hypercalcemia by 117 mg/l. The histological examination of a ganglionar biopsy concluded to a diffuse T lymphoma with great cells. The HTLV-1 serology was positive. The cutaneous lesions were due to a phaeohyphomycosis of Exophiala jeanselmei. The symptomatic therapeutic measures had been applied and he died within four weeks in a septicemic clinical manifestation. The adult T-cells lymphoma leukemia due to the HTLV-1 ought to be researched before any lymphomatous and leucemic manifestation by T-cells through a serological research. The prognostic stays very bad.

Prostate's surgery is an haemorrhagic one owing to difficulties of surgical haemostasis and anomalies of the blood coagulation. The aim of this study to assess haemostasis anomalies after protatectomy for benign prostatic hyperplasia (BPH). We have performed a prospective study including 50 men of more of 55 years old. All of them underwent suprapubic open prostatectomy. Significant pertubation of haemostasis, particularly fibrinolysis has been found. We have noticed fibrin degradation product in 88% of cases after intervention versus 62% before (p < 0.001) and a decrease of plasminogen rate in 94.4% of operated patients versus 82% before. The older the patient were, more important were the pertubations. Moreover, the anomalies were most important when the duration of surgery lasted more than one hour and when the BPH was voluminous. However, the disturbance of haemostasis was rarely associated to clinical symptoms. So, we do not recommend any therapeutic when clinical symptoms are absent. Biological screening the day of surgery, the day after and one week later are necessary to prevent haemorrhage.
