About stock markets predictability
Hicham Benjelloun
Journal of Economics and Behavioral Studies , 2011,
Abstract: We argue that the financial markets have a predetermined outcome. They behave deterministically but appear to follow random patterns. Stock prices have nothing to do with future expectations; they are a reflection of previous convictions coming from the confident investors. A financial crisis is the result of the lack of confidence that characterizes a market moments before the crisis. Stocks returns are perfectly correlated to each other and it is possible to obtain high gains consistently. Finally we provide a different way of assessing risk and suggest a method to sense future performances.

Annular pancreas is a rare congenital anomaly characterized by the presence of ectopic pancreatic tissue surrounding the duodenum. This malformation is usually asymptomatic in adults, but can manifests as pancreatitis, duodenal stenosis, or duodenal or gastric ulceration. We report the case of a young patient of 18 years old hospitalized for epigastric pain and vomiting, in whom radiological investigations showed an annular pancreas. At operation, a complete obstruction of the duodenum between its first and second parts was found, caused by an annular pancreas. No other congenital anomaly of the intra abdominal organs was noted. A gastroenterostomy was performed. Both the rarity of this congenital abnormality and its successful correction by surgical means have prompted us to make the following presentation.

Hemobilia Due to an Iatrogenic Arteriobiliary Fistula Complicating Laparoscopic Cholecystectomy: A Case Report  [PDF]

Open Journal of Gastroenterology (OJGas) , 2014, DOI: 10.4236/ojgas.2014.46040
Abstract: Hemobilia is the result of a pathological communication between bile duct and intra or extrahepatic vessel. 40% to 60% of the haemobilia cases are Iatrogenic, and the other causes are either vascular malformations or hepatic blunt trauma. We describe the case history of a patient in which laparoscopic cholecystectomy was complicated 3 months later by massive hemobilia. The cause of haemorrhage was a fistula between the principal bil duct and the right hepatic artery. This complication was successfully managed by surgery and angiographic embolization with full recovery of the patient.
Duplication iléale chez l’adulte révélée par une perforation
Hicham El bouhaddouti,Abdelmalek Ousadden,Youssef Alaoui Lamrani,Bachir Benjelloun
Pan African Medical Journal , 2010,
Abstract: Les duplications intestinales sont des malformations digestives rares (0,2 % des malformations de l’enfant). Elles sont diagnostiquées généralement avant l’age d’un an, mais elles peuvent rester asymptomatiques et diagnostiquées à l’age adulte. Le diagnostic est fait le plus souvent lors de laparotomie faite en urgence devant une complication. Elles sont traitées par résection chirurgicale.
Superior Mesenteric Arterial Embolism Associated with an Acute Limb Ischemia: A Case Report and Literature Review  [PDF]

Abstract: Introduction: Acute mesenteric ischemia due to an embolism of the superior mesenteric artery (SMA) is associated with a high mortality rate. Over twenty per cent of acute mesenteric embolism cases consist of multiple emboli. Case Presentation: We present a rare case of a 62-year-old man admitted with acute abdominal pain and signs of intestinal occlusion related to an acute mesenteric ischemia due to superior mesenteric arterial embolism. It was associated with a synchronous acute bilateral lower limb ischemia due to embolic arterial occlusion. He underwent an emergency explorative laparotomy with proximal jejunal resection, and the patient made an excellent recovery. As for the acute limb ischemia, it was treated by efficient anticoagulation allowing limb salvage. Conclusion: When treating a superior mesenteric arterial embolism, the possibility of recurrent or multiple arterial thromboembolic events should be considered. A prompt diagnosis, aggressive surgical treatment and intensive care could improve the prognosis.

Abstract: Intussusception in adults is rare and accounts for 1% to 5% of cases of acute bowel obstruction. Moreso, colic intussusception remains exceptional in adults and is usually secondary to an endoluminal lesion. Abdominal intestinal lipomas are rarely responsible for colonic invagination. They are often located on the caecum or the ascending colon and rarely on the left colon. We report the case of colo-colic invagination on a descending colon lipoma in a 50-year-old woman.
Extragonadal mixed germ cell tumor of the right arm: description of the first case in the literature

Abstract: We report the case of a 37-year-old man who presented with a primary malignant mixed non-seminomatous GCT (teratocarcinoma variety) in the right arm, treated by a combination of cisplatin-based chemotherapy and surgery. After 18 months of close follow-up, no locoregional recurrence or distant metastases have been detected.A combination of chemotherapy and surgery is the most appropriate treatment strategy for extragonadal GCTs, to ensure both local and systemic control.Germ cell tumors (GCTs) are classified as extragonadal if there is no evidence of a primary tumor in either the testes or ovaries [1]; they typically arise in midline locations. In adults, the most common sites, in order of frequency, are the anterior mediastinum, retroperitoneum, and the pineal and suprasellar regions. To date, there have been no reported cases of germ cell tumors arising in the arm.The aim of the present work was not only to report what is to the best of our knowledge the first observation of a mixed non-seminomatous GCT of the arm, but to also increase exposure of the various hypotheses that could explain this unusual location. We also discuss the diagnosis, treatment, and prognosis of this entity.A 37-year-old man presented with a 2-year history of painless swelling of the right arm with a gradual increase in size. A physical examination was normal except for a well circumscribed non-tender mass in the upper two-thirds of the right arm and multiple lymph nodes in the right axilla. Imaging revealed a 53?×?40 mm diameter soft tissue mass that was hyperintense on T2-weighted MRI in the posterior compartment of the right arm, with no bone or vascular invasion (Figures 1 and 2). Surgical biopsy of the mass and axillary lymph node excision were performed; the laboratory received two fragments with soft consistency, measuring 2?×?1?×?0.3 cm and 2.5?×?1?×?0.5 cm. Histopathological examination showed a desembryoplastic multitissular tumor, containing a sarcomatous component constituted by
Pneumatose kystique iléale révélée par un volvulus du grêle
Hicham El bouhaddouti,Abdelmalek Ousadden,El Bachir Benjelloun,Karim Ibn Majdoub
Pan African Medical Journal , 2010,
Abstract: La pneumatose kystique intestinale est une pathologie rare qui se caractérise par la présence de kystes gazeux dans la paroi intestinale. Elle est asymptomatique ou pauci symptomatique, et le plus souvent découverte lors d’un examen d’imagerie ou d’endoscopie. Nous rapportons un cas de pneumatose iléale compliquée d’un volvulus sur bride chez un patient jamais opéré auparavant.

Abstract: Neuroendocrine tumors (NET) of the gallbladder are a rare entity with only 0.2% of all NET located in the gall bladder. Well-differentiated NETs occur at a relatively lower age group unlike other gallbladder tumors, whereas neuroendocrine carcinoma (NEC) occurs in an older category of patients. The aim of our study is to discuss the current level of evidence regarding this pathological entity by means of a rare case report on a neuroendocrine carcinoma of the gall bladder in a 63-year-old patient with a history of diabetes. Patient underwent cholecystectomy for acute cholecystitis. Pathology findings on surgical specimen came back for neuroendocrine tumour.
Nordic Container Port Sustainability Performance—A Conceptual Intelligent Framework  [PDF]
Moulay Hicham Hakam
Journal of Service Science and Management (JSSM) , 2015, DOI: 10.4236/jssm.2015.81002
Abstract: There is a lack of both integrative frameworks for container ports and dedicated ones to the Nordic region as observed in the literature. The purpose of this paper is to fill that gap by proposing a conceptual intelligent sustainability performance management framework for Nordic container ports. First a description of such framework is given where the application of artificial intelligence is vital. Then, scanning the literature for performance measurement, features of ports in the Nordic region and port sustainability is undertaken. A dedicated list of key performance indicators is suggested. Finally, a prototype based on hypothetical data is developed for demonstration purposes.
