We describe a new case of duodenal wound with complete transection in a 22-year-old patient following a motorcycle accident. He presented to the emergency room of the rural Regional Hospital of Edéa in Cameroon with a clinical picture of acute abdomen and post-trauma hemodynamic instability. A peritoneal puncture brought back an incoagulable blood. An exploratory laparotomy revealed a large hemoperitoneum mixed with food debris. A tear of the omentum and transverse mesocolon and a complete section of the third duodenum at the beginning of its free portion were observed. The surgeon performed emergency closure of both duodenal stumps and performed an isoperistaltic lateral gastrojejunal bypass. A transfer to a specialized center for a more anatomical continuity was considered, but the imminence of a humanitarian mission in the hospital prompted the surgeon to seize the opportunity of this mission for the reoperation. This surgical revision was performed on the fifth postoperative day. A resection of the distal duodenal stump and the adjacent jejunal segment including the anastomosis was performed. Continuity was restored by a mechanical duodenal-jejunal anastomosis. The patient was discharged on the 18th postoperative day. This type of lesion is difficult to manage in an emergency situation in a structure with limited technical resources. Unfortunately, surgeons treating polytraumatized civilians are encountering an increasing number of blunt duodenal wounds requiring laborious management.

Gallstone ileus is a rare complication of cholelithiasis and a type of mechanical obstruction involving impaction of a gallstone within the intestinal tract [1,2]. This entity occurs in 0.15% - 1.5% of cholelithiasis cases and < 0.1% of ileus cases overall [1]. Gallstone ileus is more common in the elderly and up to 80% - 90% of affected patients have medical comorbidities [2]. The ratio of occurrence in females to males is 3.5:1 [3]. The following report presents a case of gallstone ileus with associated perforated small bowel diverticulitis, demonstrating the importance of considering this condition as a differential diagnosis of an acute abdomen.

The aim of this publication is to present case reports to show what is possible with pterygoid implants for the rehabilitation of edentulous space in the jaw (maxilla) while avoiding sinus lifts and bone grafting procedures. In addition, the added value of one-piece implants for screwed retention is elucidated.

This case report presents in-vivo findings on the spatial and temporal relationship between focal Ab-amyloid deposition, cerebral micro-haemorrhages and superficial siderosis. A 65-year-old woman underwent 11C-PiB PET scans that revealed an atypical focal and asymmetrical pattern of Ab-amyloid deposition and MRI scans that revealed cerebral micro-haemorrhages and superficial siderosis. Almost all micro-haemorrhages were associated with focal Ab-amyloid deposition. Follow-up 11C-PiB PET and MRI scans showed progression of the disease. We speculate that Abamyloid deposition affects the structural integrity of arterioles, thereby predisposing them to micro haemorrhages. In support of this hypothesis, progression of MRI lesions was observed only in areas associated with Ab-amyloid deposition.

A case of oncocytic papillary cystadenoma in a 72-year old woman, a rare tumor of laryngeal seromucinous glands of unclear nature is presented. The patient had a history of chronic inflammation of laryngeal mucosa and both her age and tumor location were typical. The lesion was resected transorally without complications. Histological findings are shown in the present study. The controversial status of oncocytic papillary cystadenoma as either a true neoplasm or a combination of metaplastic and hyperplastic changes, its resemblance to Warthin’s tumor and optimal approach to treatment are discussed.

Bladder carcinomas have a great propensity for divergent differentiation with more that 90% being Transitional cell carcinoma. Several histological variants have been have described so far; they are not only morphologically unique but also have significant prognostic and therapeutic differences making their timely identification of paramount importance. Osteoclastic giant cell variant of urothelial carcinoma is very rare type with controversial management. Studies from China have documented higher incidence and severity of illness in COVID-19 positive cancer patients. We report an unusual case of Osteoclastic giant cell variant of urothelial carcinoma in a 63 yrs old male patient associated with simultaneous COVID-19 infection.

Acute severe Asthma is a common paediatric emergency managed according to the BTS and SIGN guidelines. They recommend that if initial β2 agonist treatment bears no response, frequent Ipratropium Bromide doses can be given every 20-30 minutes [1]. We present a case of paradoxical bronchospasm to Ipratropium, an observed but rare side effect.

Hypogastric artery aneurysms are an uncommon entity. When the diameter achieves > 30-35 mm, they should be treated. Endovascular repair may be considered as first line therapy. One therapeutic option for internal iliac artery aneurysm exclusion is its embolization with or without covering the ostium with a covered stent. They may be some complications when it is not, as a distal coil migration that may produce ischemic symptoms. We are presenting a 73-years-old male admitted to hospital with an acute right lower limb ischemia caused by a coil migration. He recently underwent a right hypogastric artery aneurysm endovascular treatment by coil embolization without covering the hypogastric ostium with a covered stent. The patient underwent an emergency surgery to remove the coil by a transfemoral surgical approach with posterior thrombectomy of the secondary thrombus. Actually, he remains asymptomatic and with right posterior tibial pulse. Covered stent placement at the common iliac artery and external iliac artery could be the best option to avoid the risk of aneurysm rupture caused by endotension and the risk of distal coil migration.

Syringomyelia in combination with inherent or acquired hindbrain abnormalities is the non seldom and at the same time controversial issue. Purpose: The etiology and pathogenesis creates a lot of discussion. Methods: Experimental syringomyelia was induced in 20 anesthetized rabbits by injecting 0.5 ml of 25% kaolin suspension into the cisterna magna. Six rabbits with puncture and injection sterile saline NaCl were used as a control. The animals were sacrificed 1, 2, 4 and 6 months after the kaolin injection. Four hydrocephalus rabbits were sacrificed in 17 hours after the puncture of lateral ventricle with injection of solution of colloidal gold labeled human albuminum. The sections of the brain and spinal cord were stained with hematoxylin and eosin by Nissle and Marchi methods and with immunogold technique. Retropharyngeal lymph nodes of the animals were examined by electron microscopy. Conclusion: Our observation showed that water hammer effect and internal destruction of the spinal cord may lead to continuous antigen stimulation of regional lymph nodes and play an important role in pathogenesis of experimental syringomyelia.

The increasing use of highly conformal radiation deliberates a higher accurate targeting. Contouring and clinical judgment are presumably the crucial point, thus positron emission tomography/magnetic resonance imaging PET/MRI with somatostatin analogs appears to be useful in radiotherapy target definition. A case report of a 43-year-old woman presented with a recurrence of a meningioma (World Health Organization group I classification) in skull base, 2 years after resection. Magnetic resonance imaging (MRI) revealed a left sided skull base mass on sphenoid wing, anterior clinoid and with a soft tissue component in the lateral portion of the orbit. Contrast-enhanced MRI and a computed tomography (CT) dedicated were used to the radiotherapy planning. Aiming an improvement on target volume delineation, 68Ga-DOTATOC-PET/MRI was also performed due the difficult localization of the tumor in skull base. Was treated using intensity-modulated radiotherapy (IMRT) to a total dose of 54 Gy in 28 fractions. It was prescribed to the planning target volume (PTV), defined based of both imaging modalities. In our case PET/MRI helped to define the target, which volume becomes bigger than that based exclusively on MRI and CT.
