Transcendental Continued Fractions

In the present paper, we give sufficient conditions on the elements of the continued fractions $A$ and $B$ that will assure us that the continued fraction $A^B$ is a transcendental number. With the same condition, we establish a transcendental measure of $A^B.$Comment: 9page

Treatment of metastatic urachal adenocarcinoma in a young woman: a case report

A 30-year-old woman with a history of smoking presented with abdominal pain and haematuria. On physical examination, she had a palpable pelvic mass. Imaging revealed a large pelvic mass located on the dome of the bladder, extending from the urachus, with pulmonary metastases. After open biopsy, urachal adenocarcinoma was histologically confirmed. The patient received six cycles of palliative chemotherapy combination 5 fluorouracil and irinotecan with complete response on the pelvic mass and partial response estimated to more than 80% on pulmonary metastasis

Primary Malignant Melanoma of the Urinary Bladder

Introduction. Primary melanoma of the urinary bladder is very rare. As far as we know, 19 cases have been reported worldwide, usually as case reports. Case Presentation. We present a 71-year-old male patient presented with a 2-month history of hematuria. Ultrasonography revealed a 5-cm-size mass located in the bladder trigone. A transurethral resection of the bladder tumor (TURBT) revealed a malignant melanoma. Evaluation for metastatic disease was negative. The patient deceased five months later before radical treatment could be performed. Conclusion. This is one more reported case of primary melanoma of the urinary bladder. The previously reported cases of bladder melanoma are reviewed. Therapy and prognosis are discussed

Spectacularly Successful Microsurgical Penile Replantation in an Assaulted Patient: One Case Report

Penile amputation is a rare condition for which immediate surgical replantation is warranted. We present herein one case of a 27-year-old male who presented to the Emergency Department after his wife cut his penis. The penis was replanted microsurgically. The deep dorsal penile veins and superficial veins were anastomosed. Although we could not reanastomose the arteries, wound healing occurred without any problem one week postoperatively and the patient regained erectile function 4 weeks after surgery. At 1-year follow-up examinations he reported on restored erectile function and a normal urinary function

Partial Ureteropelvic Junction Disruption after Blunt Trauma: Case Report

Partial ureteropelvic junction disruption as a result of blunt trauma is rare and frequently missed by the initial trauma evaluation. Delays in diagnosis have also been associated with significant morbidity. A high index of suspicion should lead to appropriate investigations, and the management will be determined by the severity of the disruption. We present herein a 24-year-old man who was admitted to the Emergency Room with multiple organ injuries caused by a severe blunt trauma. Emergency celiotomy was performed for massive hemoperitoneum and shattered spleen which led to splenectomy. The diagnosis of partial UPJ disruption was missed preoperatively and suspected in CT scan after appearance of flank tender mass. Confirmation was obtained in retrograde ureteropyelography and treated conservatively with indwelling ureteral stent. We present herein an extensive review of the literature to examine the current status of this entity and to determine if improvements could be made in the diagnosis and treatment

Conservative Management of a Congenital Seminal Vesicle Cyst Associated with Ipsilateral Renal Agenesis Revealed by Cystitis: One Case Report

Seminal vesicle cyst is an extremely rare disease. Its association with ipsilateral renal agenesis is even more exceptional. We present herein one case of a 16-year-old male who presented with a four-month history of lower urinary tract symptoms (LUTSs) and micturition pain. The digital rectal examination revealed a small mass arising from the prostate. The urine culture showed that E. coli is sensitive to all antibiotics tested. Transrectal ultrasound (TRUS) revealed a cystic mass in the outer prostate. Seminal vesicle cyst and left renal agenesis were confirmed by magnetic resonance imaging (MRI). Maximum flow (Qmax) at uroflow was greater than 15 mL/sec. We therefore decided to manage this disease conservatively with alpha blockers and antibiotics. After 6-month' followup the patient did not report any complain and the uroflow test was similar to a normal urination. From one case report and literature review, the authors suggest a diagnostic and therapeutic strategy for the management of this rare condition

Anaplasic lymphoma kinase positive inflammatory myofibroblastic tumour with renal pelvic calculus: a case report

Inflammatory myofibroblastic tumour is a distinctive mesenchymal neoplasm, composed of a variable admixture of myofibroblastic spindle-shaped and inflammatory cells which were originally described in the lung, as a nonneoplastic lesion and designated as an inflammatory pseudotumour. The lack of certainty of the IMTs pathogenesis is reflected in the large number of terms which have been attributed to this lesion. Recent genetic and molecular studies of IMTs have showed chromosomal abnormalities of 2p23 resulting in a rearrangement of the anaplasic lymphoma kinase gene and have also provided evidence for a monoclonal, noeplastic origin for IMT.Occurrence of IMT in the kidney is very rare, and to our knowledge, only 30 such cases have been described in the literature.This report describes an original case of an ALK positive IMT of the kidney associated with renal pelvic calculus which we believe has never been reported. The differential diagnosis of IMTs will also be discussed

Pheochromocytoma of the urinary bladder: a case report

Urinary bladder pheochromocytoma is rare. From a case report of unsuspected pheochromocytoma and literature review, the authors develop a diagnostic and therapeutic algorithm for the management of this ectopic pheochromocytoma localization

Epididymal Leiomyosarcoma: One Case Report

Epididymal leiomyosarcoma is very uncommon. Only 16 cases have been reported in the literature. There has never been a reported case of a patient with an African origin with this tumor. We report the medical history of a 70-year-old man who presented an enormous mass located in his epididymis. A tricut biopsy was performed which allowed histological confirmation of epididymal leiomyosarcoma after which the patient underwent excision of the mass. The patient died after the first round of chemotherapy
