ABSTRACT
Acute intussusception is a pathology of infants and young children. Its occurrence in adults is rare. It is of various etiology. In the vast majority of cases, it is secondary to a tumor which can be benign or malignant. We report the case of a 77-year-old patient, admitted to the emergency department of our structure for an acute intestinal obstruction, an abdominal CT scan showed acute small intestine intussusception on a small intestine tumor complicated by perforation. Treatment was open surgical resection. The anatomopathological and immunohistochemical study of the surgical specimen concluded to a small intestine GIST. From this new case and after analysis of the literature, we discuss the clinical and diagnostic characteristics and the therapeutic possibilities of this rare pathology.

ABSTRACT
Odontogenic keratocyst (OKC) and ameloblastomas are distinct histopathologically diagnosed odontogenic lesions of the oral cavity. Both are primarily located in the posterior regions of the mandible, however, they can involve the maxilla as well. The occurrence of both an OKC and ameloblastoma in a patient is very uncommon. In this case reports we present a case of 17 year old male with histological features of both odentogenic keratocyst and ameloblastoma.

ABSTRACT
Introduction: There are certain basic facial features such as the hairline shape, which is a prominent feature on the forehead, that are considered to be morphogenetic and useful anthropologically in identifying individuals, family ties, and differentiating tribes or races from each other. The pattern of the curved hairline is also referred to as the "widow's peak." The hairline shape can be broadly classified as being straight or curved (widow's peak) in shape. People with curved hairlines (widow's peaks) have prominent v-shaped hairlines; this structure can be used as a distinguishing characteristic of a people, or tribe, in anthropology. The dearth of information on the pattern of hairline shape informed the study on the Idoma people of Benue State, Nigeria. Materials and Methods: The study was community-based, descriptive, and cross-sectional with a sample size of 401. Data was collected using a closed-ended questionnaire that was administered by an interviewer following an examination of the hairline shape. Results and Discussion: The distribution of hairline shape amongst the participants was thus: curved 267 (66.6%), and straight 134 (33.4%). There were no significant socio-demographic characteristics among participants (p > 0.05). Conclusions: The study indicated that 2 in 3 people in the population have a curved hairline. While about a third of the sampled population had a straight hairline. The distribution of hairline shape with respect to gender showed the curved hairline shape was predominant over the straight in both genders. The ratio of curved to straight hairlines (2:1) was seen in both genders. The most plausible explanation for the common occurrence of a curved hairline over a straight one could be genetic input.

ABSTRACT
Inguinal hernias are 75% off all abdominal wall hernias, life time risk of developing hernias is 24%. In the present study to analyze age incidence, type of complications and duration of presentation to analyze post operative to analyze the post-operative complications in inguinal hernia swelling like infection, chronic grin pain, hematoma, scrotal swelling and recurrences, at the end of study Lichtenstein hernioplasty has least complications, ambulate early, return to work early, less post operative pain, reduced incidence of chronic groin pain and least recurrence after surgery was concluded.

ABSTRACT
Pseudoaneurysms are post-traumatic anomalies affecting the vascular layers occuring usually after a trauma. Their treatment, consensual in the adults, lacks guidelines in the pediatric population due to rare cases in children. We report three cases of pediatric pseudoaneurysms treated surgically in our hospital.

ABSTRACT
Introduction: The pyelo-ureteral junction syndrome is defined by a dilation of the renal pelvis and the calyxes with a downstream ureter of normal caliber. It is a fairly frequent pathology often of congenital cause whose diagnosis can be ante-natal or post-natal thanks to ultrasound. The treatment is surgical especially if there are clinical manifestations. The objective of this work is to study in general the pyelo-ureteral junction syndrome in the pediatric surgery department of the Mali hospital. Material and Methods: This was a prospective study which took place at the Mali hospital from May 2018 to April 2021. This study included all patients aged 0 to 15 who were operated on for pyelo-ureteral junction. Results: During the 3-year study period, we collected 12 cases of pyelo-ureteral junction syndrome. The average age was 3 years with extremes of 20 days and 14 years. All patients had an abdominal mass accompanied by abdominal pain in 83.3% of cases. Dehydration was present in 66.66% of patients. The attack of the left kidney was predominant is 66.66% of the patients, in only one patient the expectation was bilateral. Serum creatinine was normal in all patients. Cytobacteriological examination of urine found 2 cases of Echerichia coli infections. 10 pyeloplasties and 2 nephrectomies were performed with simple postoperative course. Conclusion: The pyeloureteral junction syndrome is a frequent pathology in the literature but not very frequent in our daily practice. Most of our diagnoses are made post natally. It is not very symptomatic, mainly affecting male infants. Ultrasound and Uro scanner have a very important role in the exploration of this pathology. Open-air surgery is the technique of choice in our context.

ABSTRACT
For several years, the surgical treatment of post-traumatic osteoarthritis of the ankle was essentially based on arthrodesis. Currently, ankle arthroplasty has become a reliable alternative with the development of new prostheses. However, the total ankle prosthesis cannot be offered to all patients and it is often a source of medium and long-term complications. The management of these complications, in particular that of the loosening of the prosthesis, is generally done by a definitive treatment by arthrodesis after removal of the prosthesis. It is necessary to combine it with a bone graft in order to fill the gaps left after the removal of the prosthesis and thus allow consolidation with fixation of the joint.
