Abstract
Progress in skull-base endoscopic surgery has improved our knowledge of olfactory cleft (OC) anatomy. This article presents a review of current knowledge concerning the OC roof: descriptive anatomy, radiological exploration, and endoscopic observation. The OC is a narrow area in the most superior part of the nasal cavity. Its roof is the thinnest structure separating the nasal cavities from the brain; it comprises three superimposed tissues: nasal mucosa, ethmoid cribriform plate (ECP), and dura mater. The ECP comprises the anterior ECP containing the ethmoidal slit (ES) medially and the cribroethmoidal foramen (CEF) laterally; and the posterior ECP, comprising the olfactory foramina. The OC roof is bordered anteriorly by the nasal bone roof, laterally by the lateral ethmoid masses, and posteriorly by the jugum and anterior wall of the sphenoid sinuses. Imaging is crucial for analyzing this wall, providing precise detailed information on conformation and anatomic relations with adjacent structures such as the anterior ethmoidal artery. Understanding OC roof anatomy and correct interpretation of imaging are essential for safety in present-day functional endoscopic sinus surgery and anterior skull-base oncologic surgery.

Abstract
BACKGROUND Incidence of oral tongue squamous cell carcinoma (OTSCC) is increasing, especially in young adults, despite decreasing tobacco and alcohol consumption. METHODS This multicentric retrospective study of 185 young adults with OTSCC (median follow-up 43 months), investigated risk factors, tumour characteristics and oncological outcomes according to the smoking status. RESULTS Overall, 38% of patients were smokers (S). Non-smokers (NS) were significantly younger than S. Sex ratios were 1.1 for N and 1.8 for S. NS patients were less frequently cannabis or alcohol users than S, but were more likely to have a history of leukoplakia. Second primaries were observed in NS (4.4%) and in S (12.7%). Despite more frequent local relapse in NS (p = 0.018), there was no difference in diagnostic stage and overall survival between groups. CONCLUSION OTSCC affects differently young S and NS patients suggesting the existence of a specific clinical entity of OTSCC in non-smoking young adults.

Abstract
BACKGROUND/AIMS In several studies markers of hepatitis C virus infection have been shown to be present in alcoholic patients with cirrhosis. Our work was designed to test the likely hypothesis that this association is due to an interaction between hepatitis C virus and alcohol in the pathogenesis of cirrhosis. METHODS We compared alcohol consumption and repartition of anti-HCV antibodies detected by an immunoblot recombinant assay in 101 male patients with cirrhosis and in 120 male controls. Interactions between anti-hepatitis C virus, alcohol and cirrhosis were calculated using log linear hierarchical models for frequency data. The basis of the method is that an interaction between hepatitis C virus and alcohol implies that a model built on the hypothesis of a role of hepatitis C virus and alcohol in the disease should be improved by a coefficient associated with multiplicative effects of hepatitis C virus and alcohol. RESULTS In patients with cirrhosis the mean alcohol consumption (148 +/- 100 g per day) and the incidence of positivity for anti-HCV antibodies (45%) were significantly higher than in controls. The results were consistent with a theoretical model built with the hypothesis of an independent role of both alcohol and hepatitis C virus. The goodness of fit between this model and the actual distribution of alcohol consumption and hepatitis C virus markers was not improved by introduction of an interaction between hepatitis C virus and alcohol. CONCLUSIONS In alcoholic subjects with hepatitis C virus infection, the probability to have cirrhosis seemed to be explained by additive effects of alcohol and hepatitis C virus. From a purely statistical point of view, no interaction between hepatitis C virus and alcohol consumption on a multiplicative scale could be demonstrated.

Abstract
In this study, the authors report two observations of granulomatous hepatitis. The secondary appearance of a mononucleosis syndrome, three weeks after the onset of fever, in healthy adults, evoked the diagnosis of a cytomegalovirus infection. The authors insist on the histologic and virologic differences of the CMV infection between the healthy adults and the immunodepressed patients. They also note the difficulties of the diagnosis of the CMV infection in healthy adults.

Abstract
To assess the prevalence of intestinal protozoans in French HIV-infected patients, stool samples, duodenojejunal biopsies, and/or colorectal biopsies from 81 patients were studied for parasites, viruses, and bacteria. Pathogens were found in 70.6% of AIDS patients with diarrhea or malabsorption. The respective prevalence of protozoa in AIDS patients with diarrhea was Cryptosporidium sp.: 37.3%, Blastocystis hominis: 13.7%, Giardia intestinalis: 5.8%, Isospora belli: 2%, Enterocytozoon bieneusi: 2%. Microsporidia were noted in one patient with severe malabsorption but no diarrhea. Other pathogens included cytomegalovirus in 27.4% and Mycobacterium avium in 5.8%. Patients with identified pathogens were more immunosuppressed and more severely malnourished than those with unexplained diarrhea. Multiple pathogens were found in 13 of 81 patients (16%). Twenty-six of 66 identified pathogens (40%) were diagnosed only on biopsy specimens. Chronic diarrhea in HIV patients could be explained in the vast majority by appropriate gastrointestinal investigations. Cryptosporidia played a major role, while microsporidia appeared to be less common.
