    Congenital polyps of the posterior urethra are rare lesions, and have often been described in boys. The polyps are benign lesion usually lined by a transitional epithelium, but cases of squamous or intestinal metaplasia have been reported

    In this chapter, the correlation between structure and electrical properties of Na2MP1.5As0.5O7 (MII = Co and Cu) are treated. The structural study shows that the cobalt and copper isotype materials can be crystallized in the tetragonal and monoclinic systems, respectively. The electrical study using impedance spectroscopy technique showed that these mixed diphosphate diarsenates are fast electrical conductors; however, the cobalt material exhibited more conductive property than the copper compound. In addition, the powder perovskite manganites La0.7M0.2M’0.1MnO3 (M = Sr, Ba and M’ = Na, Ag and K) have been prepared using the conventional solid-state reaction. The structural, magnetic, and magnetocaloric properties of these perovskite manganites compounds were studied extensively by means of X-ray powder diffraction (XRD) and magnetic measurements. These samples were crystallized in the distorted rhombohedral system with R3c space group. The variation of magnetization (M) vs. temperature (T) reveals that all compounds exhibit a second-order ferromagnetic to paramagnetic phase transition in the vicinity of the Curie temperature (TC). A maximum magnetic entropy change, ΔSMMax, of 4.07 J kg−1 K−1 around 345 K was obtained in La0.7Sr0.2Na0.1MnO3 sample upon a magnetic field change of 5 T. The ΔSMMax values of La0.7Ba0.2M’0.1MnO3 are smaller in magnitude compared to La0.7Sr0.2M’0.1MnO3 samples and occur at lower temperatures

    An acute urinary retention in an old man caused by a giant müllerian duct cyst: a case report

    Müllerian duct cysts result from an abnormality in regression of the Müllerian system. They may occasionally give rise to symptoms. We report an unusual case of acute urinary retention in an old man caused by a giant Müllerian duct cyst

    Unexpected Small Urinary Bladder Pheochromocytoma: A Nonspecific Presentation

    Objectives. Pheochromocytoma of the urinary bladder is an extremely rare tumor that typically presents with a hypertensive crisis during micturition. Preoperatively, it may be misdiagnosed due to nonspecific symptomatology, physical, and radiologic findings. Method. We report a case of unsuspected small pheochromocytoma which was incidentally found by CT scan and confirmed by the histological aspects after transurethral resection in a 63-year-old woman. Here, we have described the clinical presentation, physical findings, laboratory investigations, and treatment provided in our case. We have also included radiological images and histopathology slides with input from both radiologists and pathologists. Surgical management and postoperative follow-up are discussed, as are details of previous published data. Results. After undergoing surgical treatment (transurethral resection), our patient is asymptomatic, with complete resolution of her pathology. Conclusion. Diagnosis is difficult before histopathological examination and should be considered in patients with no risk factors for usual bladder tumor. Our purpose is to raise clinician's awareness for this condition so that they will be more likely to diagnose it. This will facilitate prompt diagnosis and treatment and especially prevent complications due to pheochromocytoma which may be severe

    Mixed nutcracker syndrome with left renal vein duplication: A severe and exceptional presentation in an 18-year-old boy

    The nutcracker syndrome (NCS) is rare and often misdiagnosed because it embraces an extended non-pathognomonic spectrum of symptoms that imply a difficult diagnosis. Ultimately it may be associated with substantial morbidity and even life-threatening events. Mixed NCS with renal vein duplication is an exceptional variety, have previously been reported to the best of our knowledge. We report a rare case of an 18-year-old boy who presented with a long history of abdominal, pelvic and left flank pain, fatigue and higher bilateral varicocele. Computed tomographic angiography, Doppler ultrasonography and venography were performed revealed left renal vein duplication with dilated retroaortic and preaortic branchs, entrapped respectively between the aorta and the vertebral column and in the aortico-mesenteric space, with extensive and complex varices of the deep pelvic venous plexus; promoting the mixed renal NCS. Auto transplantation of the left kidney was suggested, but refused by the patient; and only the varicocele was managed. The patient is still suffering from his severe initial symptoms. Diagnosis is difficult and should be considered in patients with inexplicable flank or abdominal pain. Our purpose is to raise clinician′s awareness for this condition so that they will be more likely to diagnose it. This will facilitate prompt diagnosis and treatment

    Modified medial nephropexy for treatment of the anterior nutcracker syndrome

    No full text
    We report the case of a 15-year-old male, presenting with recurrent gross hematuria complicated by acute anemia. Cystoscopy showed little bleeding from the left ureteral orifice. Diagnosis of left renal vein compression at the aortomesenteric space was established through color Doppler ultrasonography and computed tomographic angiography. Therapeutic attitude was interventionist in our case, performing successful management with modified medial nephropexy, with a retroperitoneal approch. To the best of our knowledge, we report the second case of left medial nephropexy for treatment of the anterior nutcracker syndrome. The first case of modified medial nephropexy was done by lowering the left renal vein from its initial position in the aortomesenteric angle through a restrict retroperitoneal approach

    <p>Abstract</p> <p>Introduction</p> <p>Renal infarct is rare and often misdiagnosed because the symptoms are misleading. The mechanisms are various, mainly thrombotic and embolic.</p> <p>Case presentation</p> <p>In this review, we report the case of a 61-year-old Tunisian woman presented to the emergency unit with a 4-hour history of abdominal pain diffused at both flanks, ultrasounds was performed to remove a surgical emergency, showed a peri-renal fluid collection with heterogeneous parenchyma.</p> <p>We followed by a CT scan, which confirmed the diagnosis of renal infarct. The patient was treated by heparin at a curative dose, and the outcome was favorable.</p> <p>Conclusion</p> <p>Diagnosis is difficult and should be considered in patients with inexplicable flank or abdominal pain and with risk factors to this disease. Our purpose is to raise clinician’s awareness for this condition so that they will be more likely to diagnose it. This will facilitate prompt diagnosis and treatment.</p> <p>A review of the literature was performed and the case is discussed in the context of the current knowledge of this condition.</p
