Primary adenocarcinoma of the upper esophagus: A rare presentation.

INTRODUCTION AND IMPORTANCE: Cervical esophageal cancer is a rare condition, accounting for less than 5 % of all esophageal malignancies. CASE PRESENTATION: We report here a case of a 65-year-old female patient with a history of breast cancer diagnosed in 1985 treated with surgery, adjuvant chemotherapy, and radiotherapy. This woman presented with chronic organic high dysphagia to both solid and liquids and food impaction. Gastroscopy showed a stenosing esophageal budding tumor located at 20 cm from the incisors. Histological examination showed a well-differentiated adenocarcinoma. CLINICAL DISCUSSION: The diagnosis of primary adenocarcinoma of the upper esophagus is based on a combination of clinical presentation, imaging studies, and confirmed by histopathological examination. Upper digestive endoscopy is the gold standard for the diagnosis of esophageal cancer. CONCLUSION: Primary adenocarcinoma of the upper esophagus is a rare form of esophageal cancer.

Gastrojejunocolic fistula: a rare complication of peptic ulcer surgery.

Gastrojejunocolic fistula (GJF) is a very rare complication of peptic ulcer surgery. Patients with this condition often present with diarrhea, fecal vomiting as well as weight loss. Here, we report a case of 62-year-old male with a GJF complicating upper gastrointestinal surgery.

Adenocarcinoma of the small bowel revealing celiac disease in an adult: case report.

Cancer of the small bowel is a rare malignancy. With an incidence of less than one per 100 000 people, it makes up only 5% of all gastrointestinal tract cancers. Celiac disease is a relatively common pathology and is often associated with the development of small bowel lymphoma. However, it is also a known risk factor for small bowel adenocarcinoma. The authors are reporting a case of a patient with recurrent bowel obstruction found to have a small bowel adenocarcinoma and an underlying celiac disease.

Overlap syndrome of primary biliary cholangitis and primary sclerosing cholangitis: two case reports.

BACKGROUND: Overlap syndrome between primary biliary cholangitis and primary sclerosing cholangitis is an extremely rare condition that has been reported in only few published cases so far in the literature. We highlight here the rarity of this condition and indicate the importance of its recognition. CASE PRESENTATION: We report two cases showing the manifestations of both primary biliary cholangitis and primary sclerosing cholangitis in two Tunisian female patients aged 74 and 42 years, respectively. The first case is a woman who was initially diagnosed with decompensated cirrhosis. Magnetic resonance cholangiopancreatography showed multiple strictures of the common bile duct, and histological findings led to the diagnosis of primary biliary cholangitis/primary sclerosing cholangitis. She was successfully treated with ursodeoxycholic acid. The second case is a middle-aged woman, suffering from primary biliary cholangitis and who was treated with ursodeoxycholic acid. At her 12 month follow-up appointment, she presented with a partial clinical and biochemical response. Tests showed normal thyroid function, liver autoimmune tests for autoimmune hepatitis were negative, and celiac disease markers were also negative. The diagnosis of overlap syndrome of primary biliary cholangitis/primary sclerosing cholangitis was finally made on the results of magnetic resonance cholangiopancreatography that showed multiple strictures of the common as well as intrahepatic bile ducts. The patient was put on ursodeoxycholic acid at a higher dose. CONCLUSIONS: Our cases raise awareness for this rare condition and indicate the importance of recognizing a possible overlap syndrome, especially in patients with primary biliary cholangitis, to optimize treatment. We suggest considering the overlap syndrome of primary biliary cholangitis/primary sclerosing cholangitis when a patient presents with the diagnostic criteria of both diseases.

Tunisian consensus on the management of Helicobacter Pylori infection.

Helicobacter pylori infection is the most common infectious disease worldwide. It is associated with duodenal and gastric ulcer disease and the risk of gastric neoplasia. The management of helicobacter pylori infection currently represents a real challenge for clinicians, given the ever-increasing rate of resistance of Helicobacter pyolori to various antibiotics. In this consensus document, we present recommendations adapted to the Tunisian context, including indications for the detection of helicobacter pylori infection, indications for the use of different diagnostic methods, and a therapeutic strategy for the management of Helicobacter pylori infection.

Gastric polyps: a 10-year analysis of 18,496 upper endoscopies.

BACKGROUND/AIMS: Gastric polyps (GPs) are usually asymptomatic lesions of the upper gastrointestinal tract observed in 1-3% of esophagogastroduodenoscopies (EGD). Most GPs are benign. The aim of this study was to precise the frequency of different types of gastric polyps in our population, and to analyze their possible association with other factors. MATERIALS AND METHODS: A total of 18,496 consecutive patients undergoing EGD over a 10-year period (between 2007 and 2018) in a tertiary hospital were retrospectively reviewed. Eighty-six patients diagnosed with gastric polyps were analysed. Demographics, medical history of the patients, and indication for gastroscopy were collected. Morphological, histological characteristics of polyps, and therapeutic management data were also collected. RESULTS: GPs were found in 86 out of 18,496 (0.46%) reviewed EGD, corresponding to a total of 141 polyps. There were 64 female (74.4%) and 22 male patients (25.6%) with a sex ratio (M/F) of 0.34. The average age was 58.1 years. One hundred and forty one polyps were included, and histopathology was obtained on 127 GPs. The most common location was the fundus (59.6%) and 48.9% were smaller than 5 mm. The polyp was unique in 75.6% of cases. According to Paris classification, 80% of the polyps were sessile (Is). Hyperplastic polyps were the most common (55.9%), followed by sporadic fundic gland polyps observed in 23 patients (18.1%), 7 (5.5%) were adenomas and 4 (3.1%) were neuroendocrine tumors type 1. The following factors were associated with hyperplastic polyps: anemia (p = 0.022), single polyp (p = 0.025) and size ≥ 5 mm (p = 0.048). Comparing hyperplastic polyps' biopsies to resected polyps, no difference was found in the evolutionary profile of the 2 groups. A size less than 10 mm (p = 0.013) was associated with fundic gland polyps. Sixty polyps (47.2%) were treated by cold forceps, 19 (15%) treated by a mucosal resection and 15 (11.8%) with diathermic snare. Five procedural bleeding incidents were observed (3.9%). Only the use of anticoagulant treatment was associated with a high bleeding risk (p = 0.005). The comparative histological study between specimens of biopsied GPs and endoscopic polypectomy led to an overall agreement of 95.3%. CONCLUSION: In our study, the GPs frequency was 0.36%. Hyperplastic polyps and fundic gland are the most common in our country. The high frequency of Helicobacter pylori infection in our patients and in our area may explain the high frequency of HP.

Cannabinoid Hyperemesis Syndrome: A Case Study in a Tunisian Young Man.

The increasing prevalence of cannabis use in the world requires awareness of cannabis-related disorders such as cannabinoid hyperemesis syndrome. This syndrome includes cyclic episodes of nausea, vomiting, and the learned behavior of hot bathing in individuals with chronic cannabis use. We present the case of a suspected cannabinoid hyperemesis syndrome that required a review of the literature to retain the diagnosis. The following case illustrates how cannabinoid hyperemesis syndrome awareness may lead to the diagnosis.

Intrahepatic cholangiocarcinoma mimicking a liver abscess.

Intrahepatic cholangiocarcinoma masquerading as liver abscess, and presenting with fever, is a very rare situation and should be considered in nonresolving liver abscess. Only few cases were reported in the literature. This entity is characterized by late diagnosis and poor prognosis.

Does Anemia Have a Potential Effect on Type 2 Hepatorenal Syndrome?

Background/Aims. Hepatorenal syndrome (HRS) is a form of functional renal failure arising in advanced cirrhosis and is characterized by a poor survival rate. Anemia is frequently observed during the clinical course of cirrhosis. Our study aimed to investigate the hematologic findings in patients with cirrhosis to determine the effects of anemia on renal functions in type 2 HRS and if it was a potential aggravating factor. Materials and Methods. This prospective study, in which all consecutive patients with cirrhosis were enrolled, was performed at a tertiary-level hospital (Military Hospital of Tunis) from January 2019 to June 2019. A total of 9 patients with HRS fulfilled the type 2 HRS diagnostic criteria, and 41 patients with cirrhosis without HRS were included. All data regarding patients were obtained from the medical record. Demographic data, routine hemograms, biochemical, and urinary test results were collected. Models of end-stage liver disease (MELD) and Child-Turcotte-Pugh (CTP) scores were calculated. Results. The most common etiology of cirrhosis was viral hepatitis (66%). According to the CTP score, 23 patients were in the CTP-A stage, 13 in the CTP-B stage, and 14 patients were in the CTP-C stage. Patients with type 2 HRS had significantly lower hemoglobin levels compared with non-HRS stable cirrhosis patients. As hemoglobin levels decreased, renal function worsened on patients with type 2 HRS. Patients with lower hemoglobin levels had poor prognosis and survival compared with patients with higher hemoglobin levels. Logistic regression analysis showed that lower hemoglobin levels and higher MELD and CTP scores were statistically significant for an onset of type 2 HRS. Conclusion. Renal dysfunction is a frequent complication in patients with end-stage chronic liver disease. The role of anemia in aggravating HRS in patients with cirrhosis is explained by hypoxia that can lead to microcirculatory renal ischemia. Other studies are required to determine if anemia is a precipitant factor for HRS or not.

Hepatitis B and C viral infections screening in a Tunisian IBD population under immunosuppressive therapies.

BACKGROUND: Immunosuppressive drugs have become a mainstay of therapy for the inflammatory bowel diseases (IBD). These treatments expose to a risk of hepatitis B and C reactivation. OBJECTIVE: The aim of this study was to assess the prevalence of hepatitis B and C viruses in Tunisian IBD patients on immunosuppressive treatments. MATERIALS AND METHODS: Patients with inflammatory bowel disease were consecutively recruited over a 2 years period (2017-2018). Prevalence of viral hepatitis B and C as well as clinical, biological and virological presentation, management and outcome were assessed. Factors associated to hepatitis B and C were also analyzed (SPSS software, p value <0.05). RESULTS: Seventy four patients with IBD were included: 38 women and 36 men. Among them 62 (83.8%) had CD and (16.2%) had UC. Mean age was 43.5±14.2 years. Six patients (8.1%) had at least one positive HVB marker. Hepatitis C infection was found in 4% patients. HBs Ag was positive in only one patient (1.3%) with positive HBV DNA. Anti HBc and anti HBs antibodies were positive respectively in 6 and 4 patients. Vaccination against hepatitis B was proposed for 22% of our patients with negative anti HBc antibodies and HBs Ag. Two patients presented non-severe acute hepatitis C with sustained virological response after antiviral treatment. IBD did not relapse under antiviral treatment. A 3rd patient had chronic hepatitis C infection. She was treated with Pegylated Interferon alpha and Ribavirine. No cases of viral reactivation have been reported. Noassociated factors to hepatitis B and C viral infections were identified in our study. CONCLUSION: The prevalence of hepatitis B infection in IBD patients under immunosuppressive therapy was similar to the general population, while the hepatitis C prevalence was higher than the national prevalence. Screening for hepatitis B and C viral infections is mandatory in inflammatory bowel disease patients. Vaccination against hepatitis B is highly recommended.

RESUMEN Antecedentes : Los fármacos inmunosupresores se han convertido en un pilar de la terapia para las enfermedades inflamatorias del intestino (EII). Estos tratamientos exponen al riesgo de reactivación de la hepatitis B y C. Objetivo: El objetivo de este estudio fue evaluar la prevalencia de los virus de la hepatitis B y C en pacientes tunecinos con EII que reciben tratamientos inmunosupresores. Materiales y métodos : Los pacientes con enfermedad inflamatoria intestinal fueron reclutados consecutivamente durante un período de 2 años (2017-2018). Se evaluó la prevalencia de las hepatitis virales B y C, así como la presentación, el tratamiento y los resultados clínicos, biológicos y virológicos. También se analizaron los factores asociados a la hepatitis B y C (software SPSS, valor de p<0,05). Resultados : Se incluyeron 74 pacientes con EII: 38 mujeres y 36 hombres. Entre ellos, 62 (83,8%) tenían EC y (16,2%) CU. La edad media fue de 43,5 ± 14,2 años. Seis pacientes (8,1%) tenían al menos un marcador HVB positivo. Se encontró infección por hepatitis C en el 4% de los pacientes. HBs Ag fue positivo en sólo un paciente (1,3%) con ADN del VHB positivo. Los anticuerpos anti-HBc y anti-HBs fueron positivos respectivamente en 6 y 4 pacientes. Se propuso la vacunación contra la hepatitis B para el 22% de nuestros pacientes con anticuerpos anti-HBc negativos y Ag HBs. Dos pacientes presentaron hepatitis C aguda no grave con respuesta virológica sostenida tras el tratamiento antiviral. La EII no recayó con el tratamiento antiviral. Un tercer paciente tenía infección crónica por hepatitis C. Fue tratada con interferón alfa pegilado y ribavirina. No se han notificado casos de reactivación viral. En nuestro estudio no se identificaron factores asociados a las infecciones virales por hepatitis B y C. Conclusión : La prevalencia de infección por hepatitis B en pacientes con EII bajo terapia inmunosupresora fue similar a la población general, mientras que la prevalencia de hepatitis C fue mayor que la prevalencia nacional. La detección de infecciones virales de hepatitis B y C es obligatoria en pacientes con enfermedad inflamatoria intestinal. Se recomienda encarecidamente la vacunación contra la hepatitis B.

Isoniazid-induced pellagra in a patient with Crohn's disease.

Isoniazid preventive therapy in malnourished patients with Crohn's disease has a potential of inducing pellagra but still a very rare situation. No cases of isoniazid-induced pellagra in patients with Crohn's disease were reported in the literature. Pellagra can be easily treated if timely diagnosed.
