Rethinking deep clustering paradigms: Self-supervision is all you need.

The recent advances in deep clustering have been made possible by significant progress in self-supervised and pseudo-supervised learning. However, the trade-off between self-supervision and pseudo-supervision can give rise to three primary issues. The joint training causes Feature Randomness and Feature Drift, whereas the independent training causes Feature Randomness and Feature Twist.

21 years of evolution of primary hepatic neuroendocrine neoplasm in a patient with primary sclerosing cholangitis: A case report.

Introduction And Importance: Primary hepatic neuroendocrine neoplasms(PHNEN) are among the rarest primitive neuroendocrine neoplasms. Main prognostic factor is histological. We report an unusual case of a PHNEN with 21 years of evolution in the setting of a primary sclerosing cholangitis(PSC).

Presentation with perforation of the terminal ileum and acute limb ischemia in Crohn's disease: A case report.

Introduction And Importance: Crohn's disease is a chronic inflammatory bowel disease with complex pathophysiology and multiple complications, some of which can be fatal. We report herein the management of an unusual case of Crohn's disease revealed by two life-threatening complications.

Case Presentation: A 59-year-old patient presented with an acute abdominal pain evolving for one day with a clinical presentation in favor of peritonitis by perforation of the last ileal loop and acute limb ischemia.

Deep clustering with a Dynamic Autoencoder: From reconstruction towards centroids construction.

In unsupervised learning, there is no apparent straightforward cost function that can capture the significant factors of variations and similarities. Since natural systems have smooth dynamics, an opportunity is lost if an unsupervised objective function remains static. The absence of concrete supervision suggests that smooth dynamics should be integrated during the training process.

[Solid pseudo-papillary tumor of the pancreas].

Solid pseudo-papillary tumors of the pancreas (SPTP) are rare epithelial tumors. In most cases, they occur in young woman in the second or the third decades of life. Survival after primary resection is approximatively 90% at 5 years.

[Outcomes of laparoscopic surgery for groin hernia repair: our experience in Tunisia].

Groin hernia in adults is a frequent affection in digestive surgery. Many repair techniques have been described to date, including laparoscopic surgery. Two methods are quickly adopted by the various practitioners for the surgical treatment of groin hernia using laparoscopy: laparoscopic totally extra-peritoneal (TEP) technique and laparoscopic transperitoneal inguinal hernia repair (TAPP).

Long term results of laparoscopic gastric band.

Background: Laparoscopic gastric band (LAGB) has gained popularity among the surgical community since its first description in the early 90'. Actually, it is the third most practiced bariatric procedure in the world. The mean advantage of LAGB is a low rate of early postoperative morbidity.

Surgical management of primary crohn's disease. descriptive study about 226 patients.

Background: The surgery is required in more than 80% of patients with Crohn's disease (CD). Studies before confirm the specific genetic variation of CD in the Tunisian population compared with the others ethnic groups.

Aim: This article aims to study the epidemiological, anatomical and therapeutic principles of surgical forms of CD in a cohort of Tunisian patients.

Anal imperforation in adults: Diagnostic difficulties and therapeutic options.

Anorectal malformations are congenital anomalies ranging from simple perineal fistulas to complex malformations. They are usually treated inchildhood, and exceptionally in adult. We herein report the case of a 22 years aged patient and relate the diagnosis difficulties and therapeuticoptions.

Feature-based active contour model and occluding object detection.

This paper presents a method for image segmentation and object detection. The proposed strategy consists of two major stages. The first one corresponds to image segmentation, which is based on the active contour model (ACM) algorithm, using an automatic selection of the best candidate features among gradient, polarity, and depth, coupled with a combination of them by the kernel support vector machine (KSVM).

Laparoscopic resection of gastric stromal tumors.

Gastro-intestinal stromal tumors (GIST) are the most common mesenchymal gastrointestinal tumors. The Gastric location represents 60% of cases [1,2]. Complete surgical excision remains the treatment of reference for the localized forms.

Laparoscopic ileo-cecal resection: the total retro-mesenteric approach.

Background: Ileo-cecal resection is the most performed procedure in Cohn's disease. In the last decades, the laparoscopic approach became the gold standard. The dissection can be lateral to median or median to lateral.

[Surgical management of entero-vesical fistulas in Crohn's disease].

Background: Crohn's disease (CD) is a chronic inflammatory disease of the intestine that can cause an attack by contiguity of the urinary tract. Although the shape is common and fistulizing 35% of all patients with CD, entero-urinary fistulas are rare and only seen in 2-8% of patients. aim: To report the frequency of occurrence of this complication among the group of surgical forms of CD.

Prognostic factors in gastric carcinoma after R0 resection with DII lymph node dissection. Tunisian experience.

Background: Curative resection with adequate lymph node dissection is the treatment of choice for gastric cancer.

Aim: To determine the prognostic factors after R0 resection with DII lymph node dissection.

Methods: We retrospectively assessed 126 patients who underwent R0 resection with DII lymph node dissection for gastric cancer (excluding the upper third of the stomach) in a single institution between 1991 and 2006 with median follow-up of 38.

Laparoscopic-assisted versus conventional ileocolectomy for primary Crohn's disease: results of a comparative study.

Introduction: The laparoscopic approach is becoming the gold standard in the surgical treatment of primary Crohn's disease. The aim of this study was to compare laparoscopic-assisted and open ileocolic resection for primary Crohn's disease.

Methods: We conducted a non-randomized, comparative, retrospective analysis of a prospective database from 1998 to 2010.
