Cerebral venous thrombosis during relapse of ulcerative colitis: Case report with review of literature.

Cerebral venous thrombosis (CVT) is a rare but serious complication of ulcerative colitis (UC) with a high morbidity and mortality rate. CVT is not usually readily recognized and treatment may be delayed, impacting on the prognosis. Here we are reporting 2 cases of CVT occurring during a relapse of ulcerative colitis (UC) with review of literature. The first patient was a 27-year-old woman with chronic UC who presented with headaches during a relapse of chronic UC. She was found to have cerebral venous sinus thrombosis. The second one was a 45-year-old man who presented with seizures and focal neurological symptom during a relapse of chronic UC. He was found to have cerebral venous sinus thrombosis complicated by left temporal infarction. Both of them were treated with therapeutic anticoagulation with good improvement. The presence of neurological signs in a patient with UC mostly during exacerbation period, should alert health professionals about the possibility of a CVT.

Prognostic Impact of Alpha Fetoprotein at Diagnosis on Overall Survival of Single Small Hepatocellular Carcinomas.

BACKGROUND: Alpha-fetoprotein (AFP) is a serum tumor marker used in the past for surveillance and screening of hepatocellular carcinoma (HCC) in patients with cirrhosis. Its prognostic value is still debated in the literature. The aim of this study was to evaluate the prognostic impact of the AFP rate at diagnosis on the overall survival of patients with a small HCC (<3cm) in patients with cirrhosis. PATIENTS AND METHODS: Among the 122 patients diagnosed with HCC during the study period, 49 patients had a small HCC at diagnosis, including 40,8% (N 20) patients with a negative AFP (group I) and 59,18% (N 29) with an AFP >10 ng / ml (group II). Both groups of patients were comparable for age and WHO status (World Health Organization). Patient survival was assessed by the Kaplan-Meier method. The survival at 5 years was 35.7% in group 1 vs 12.3% in group 2. The AFP level was identified as an independent prognostic factor of survival. CONCLUSION: Alpha-fetoprotein serum positivity seems to have prognostic value in patients with single small HCC.

Gastric Adenocarcinoma in a Moroccan Population: First Report on Survival Data.

BACKGROUND: Although its incidence has decreased over the last 20 years, gastric adenocarcinoma remains frequent (1,033,701 new cases worldwide per year, Globocan 2018). Its prognosis is still poor, with overall survival rates of 10 to 25% despite improvement in surgical and perioperative treatment. In Morocco, we do not have data on survival and predictors of mortality in our population, the present study aims to describe the epidemiological and clinicopathological features of gastric adenocarcinoma and the survival rate. MATERIALS AND METHODS: We retrospectively reviewed data files of 265 patients with histological diagnosis of gastric adenocarcinoma between January 2007 and June 2017. Survival was estimated by the Kaplan Meier method and prognostic factors in multivariate analysis (Cox model). RESULTS: The mean age of our population was 54.48 ±15.53 with a sex ratio M/F of 1.76. Clinical symptomatology dominated by epigastralgia episodes in two-thirds of the cases and deterioration of the general state in most cases (61.7%). Proximal localization accounted for 17.4%. According to histological classification, poorly differentiated adenocarcinoma was the most common histological type (51.7%). Metastatic or locally advanced tumors accounted for 92% of cases. Only 11% of patients received curative resection. The 5-year survival was 6%. Multivariate analysis revealed three prognostic factors: vascular invasion, advanced stage and differentiation. DISCUSSION: The high mortality of gastric adenocarcinoma in our Moroccan series is probably explained by the late stage at diagnosis. Symptoms are nonspecific and endoscopy is usually performed for advanced symptoms such as anemia, bleeding or weight loss. The main identified prognostic factors in gastric adenocarcinoma are tumor subtype (Linitic forms), stage at diagnosis, vascular and lymph nodes invasion and general performance status which correlates to available data in the literature. Besides, the age distribution of GC in our series showed that the proportion of affected young adult is high (30.6%) compared to data from developed countries varying between 6 and 15%. This age distribution can be explained by the Westernization of diet, the increase of obesity in our population and more exposure to alcohol and tobacco. CONCLUSION: Overall cancer survival in our population does not exceed 7%, a rate that remains low compared to studies published in the occidental literature. Recommendations have to be elaborated to make a strategy for screening and early diagnosis of gastric adenocarcinoma to improve the survival rate.

Epidemiology of viral hepatitis in the Maghreb.

INTRODUCTION: Viral hepatitis represents a serious public health problem in the world especially in the Maghreb where the prevalence of the 5 viruses A, B, C, D, and E remains high and varies from one Maghreb country to another, there is few published studies on these infections in our Maghreb countries. METHOD OF STUDY: Our work is a review of the literature about prevalence, the most common mode of transmission, and the most exposed population for these viruses in the Maghreb countries through published studies between 2011 and 2017. RESULT: It has been found that the Maghreb countries are endemic for the five viruses with variable prevalence from one country to another, with sometimes heterogeneous data in the same country. For hepatitis B, Mauritania is the Maghreb country most affected by this infection unlike the rest of the Maghreb countries which are moderately endemic for this virus, the lowest prevalence of VHB was noted in Morocco, the genotype the most common is the D for the majority of Maghreb countries, and the precore mutant profile is also the most common. For hepatitis C the prevalence of infection does not vary much from one Maghreb country to another, but it remains slightly higher in Mauritania. The population most exposed to the virus C in the five countries is hemodialysis patients. The most common genotype in all Maghreb countries is genotype 1 except for Libya, where genotype 4 remains the most common probably related to its borders with Egypt. For hepatitis D, Mauritania is the only Maghreb country with a high endemicity for the virus. Tunisia has the lowest prevalence for hepatitis A and E compared to the rest of the Maghreb countries, all of which are endemic for these two viruses with fecal-oral transmission. CONCLUSION: The management of these viral hepatitis is costly for the health economy and to reduce their prevalence, prevention measures must be followed like vaccination and improving hygiene conditions.

Prevalence and distribution of Helicobacter pylori cagA and vacA genotypes in the Moroccan population with gastric disease.

Helicobacter pylori infection is the etiologic agent of various gastric pathologies. The severity of disease outcome has been attributed to some H. pylori genotypes, which varies geographically. In Morocco, there are no data regarding the pattern of H. pylori genotypes; therefore, this is the first prospective study conducted in our country to investigate the genotype profiles (vacA and cagA) of H. pylori in patients with gastric pain. Endoscopic biopsies were obtained in patients attending the gastroenterology department of the Hospital University Hassan II of Fez for gastric pain and were directly used for H. pylori detection and genotyping by polymerase chain reaction (PCR). The SPSS software program was used to study the genotype correlation to different clinical outcomes. A total of 429 patients were included in this study, with an infection rate of 69.9%. cagA was detected in 42.3% of cases. However, vacA genotyping reveal a large predominance of s2m2. Infection with multiple strains was detected in 10.8% of cases and incomplete vacA was observed in 31.5%. In Morocco, vacA s1m1 was significantly associated to peptic ulcer diseases, while s2m2 was associated to gastritis. Moroccan H. pylori vacA genotype profiles differ from the Latin American, European, and South African profiles, with more similarities to the North African profile. Because of the small number of cases with gastric cancer, no correlations with H. pylori have been studied, so, further studies will be required in order to highlight the effects of those genes on this disease.

Low rectal volumes in patients suffering from fecal incontinence: what does it mean?

BACKGROUND: Rectal perception and adaptation to distension are widely heterogeneous in subjects with faecal incontinence. AIM: To quantify rectal physiology in patients with incontinence and low maximum rectal volume, according to AGA guidelines on anorectal testing techniques. PATIENTS AND METHODS: 148 patients (12 men, 136 female) with incontinence to liquid and/or solid stools were investigated. Distending isobaric procedures were carried out using an electronic barostat in order to analyse perception and adaptation of the rectum. RESULTS: Pain during isovolumic rectal distension at a level of 100 mL or less was experienced in 21 subjects (14.2%). As defined by isobaric distensions, incontinent patients with low MTV had more frequently a hypocompliant rectum (62%) when compared with those with higher MTV (31%, P = 0.046). Perception scores tended to be higher at each step of distending rectal pressure: incontinent patients with low MTV had more frequently a hypersensitive rectum (48%) when compared with those with normal or high MTV (24%, P = 0.035). Only four of 21 incontinent subjects with low MTV had an isolated hypersensitive rectum. CONCLUSION: Both sensitivity and compliance are altered in patients with low MTV. A more extensive study of the role of sensory and compliance aspects of subjects with incontinence is warranted.
