1/17. A sensitive bladder: an atypical presentation of cancer in a U.S. Army pilot.Bladder cancer is the most common cancer in the urinary tract, the vast majority (90%) of which are transitional cell carcinomas. A papilloma (grade I) lesion offers an excellent prognosis after excision, though recurrence is possible. The classic sign of bladder cancer is gross, painless hematuria. We report a case of transitional cell papillary carcinoma in an aircrew member with atypical presentation: irritative voiding symptoms without hematuria. With a careful history and physical, and aggressive clinical suspicion, an early diagnosis was made offering an excellent prognosis. The patient, an Army helicopter pilot, returned to flight status with a waiver.- - - - - - - - - - ranking = 1keywords = physical (Clic here for more details about this article) |
2/17. Neuroblastoma of the urinary bladder, preclinically detected by mass screening.BACKGROUND: Since the introduction of mass screening of infants for neuroblastoma, the incidence of neuroblastoma has increased in japan. The reason for this increased incidence is the possible inclusion of many neuroblastomas that would have regressed spontaneously and would never have been detected clinically. An extremely rare tumor at the dome of the urinary bladder in a 7-month-old infant was detected by the mass screening. methods: A case of neuroblastoma of the urinary bladder is reported with a review of the literature. The data in the japan Children's Cancer Registry are also reviewed to analyze the incidence and the site of origin of neuroblastoma for evaluation of mass screening. RESULTS: A 7-month-old female infant was referred because of a positive urine vanillylmandelic acid screening test. ultrasonography showed a solid mass attached to the urinary bladder. At laparotomy a 35 x 30 x 25-mm egg-shaped tumor was found at the dome of the bladder, and a partial cystectomy was performed. During the operation no changes in blood pressure occurred when the tumor was manipulated. Histologic diagnosis was rosette-fibrillary neuroblastoma originating in the bladder wall, with a favorable Shimada histopathologic classification. N-myc was not amplified, which predicted a favorable prognosis, and no postoperative chemotherapy was given. The patient was free of symptoms and tumor after a follow-up period of 16 months. literature review revealed that this was the second case of neuroblastoma of the urinary bladder ever reported in the world, although several cases of pheochromocytoma originating in the bladder wall had been reported. Both neuroblastoma and pheochromocytoma derive from the neural crest. The sympathogonia from the neural crest, a common stem cell, differentiates into a ganglion cell or into a secretory cell known as a chromaffin cell, able to manufacture catecholamines. The first case in the world that was reported as neuroblastoma of the urinary bladder was in a 4-month-old infant who was noted to have a 4-cm lower abdominal mass on routine physical examination. A ganglioneuroblastoma of the dome of the bladder was excised and the patient was doing well. On reviewing the japan Children's Cancer Registry, the incidence of neuroblastomas in infants has increased as well as the number of stage 1, 2, and 4s (stage 4 special) neuroblastomas since the introduction of mass screening. However, there has been no significant change in the number of stage 3 or 4 diseases diagnosed in older children. According to the japan Children's Cancer Registry, pelvic origin neuroblastoma, which has been noted to have spontaneous regression, was more frequent in the primary tumors detected by mass screening when compared with those presenting clinically. During preparation of this manuscript another case of bladder dome neuroblastoma was detected by urinary vanillylmandelic acid screening of 6-month-old infants for neuroblastoma in japan. CONCLUSION: These extremely rare cases of neuroblastoma of the urinary bladder involved children younger than 1 year of age and were incidentally detected by routine physical examination or mass screening. This raises the question of whether these tumors might have regressed spontaneously had they gone undetected and untreated.- - - - - - - - - - ranking = 21.62010578502keywords = physical examination, physical (Clic here for more details about this article) |
3/17. mycobacterium bovis BCG causing vertebral osteomyelitis (Pott's disease) following intravesical BCG therapy.We report a case of mycobacterium bovis BCG vertebral osteomyelitis in a 79-year-old man 2.5 years after intravesical BCG therapy for bladder cancer. The recovered isolate resembled M. tuberculosis biochemically, but resistance to pyrazinamide (PZA) rendered that diagnosis suspect. High-pressure liquid chromatographic studies confirmed the diagnosis of M. bovis BCG infection. The patient was originally started on a four-drug antituberculous regimen of isoniazid, rifampin, ethambutol, and PZA. When susceptibility studies were reported, the regimen was changed to isoniazid and rifampin for 12 months. Subsequently, the patient was transferred to a skilled nursing facility for 3 months, where he underwent intensive physical therapy. Although extravesical adverse reactions are rare, clinicians and clinical microbiologists need to be aware of the possibility of disseminated infection by M. bovis BCG in the appropriate setting of clinical history, physical examination, and laboratory investigation.- - - - - - - - - - ranking = 11.81005289251keywords = physical examination, physical (Clic here for more details about this article) |
4/17. nicotine dependence and withdrawal in an oncology setting: a risk factor for psychiatric comorbidity and treatment non-adherence.Highly nicotine dependent oncology patients are at high risk for psychiatric morbidity when they enter the medical care setting where smoking restrictions apply. nicotine withdrawal symptoms exacerbate cancer-related distress as well as common physical side effects of cancer treatment. This case report illustrates the management of a patient whose ongoing treatment for bladder cancer was jeopardized as a result of nicotine dependence and withdrawal. Several associated complications are described, the most serious of which were his acute anxiety and non-adherence to medical recommendations. A short-term management approach that included anxiolytics and nicotine replacement was effectively used to reduce this patient's excessive anxiety and thus facilitate compliance with stressful treatments. The severity of complications that can result from untreated nicotine dependence and withdrawal underscores the importance of assessing and monitoring smoking status in every patient. Greater staff awareness of the clinical practice guidelines regarding the diagnosis and treatment of nicotine dependence will likely result in improved patient care and compliance.- - - - - - - - - - ranking = 1keywords = physical (Clic here for more details about this article) |
5/17. Bladder leiomyoma: a rare cause of urinary stress incontinence.Lejomyoma of the bladder is an uncommon lesion and usually present as small intramural or submucosal lesions. Preoperative evaluation based on careful physical and radiologic examinations must rule out malignant and other lesions. It is readily and successfully treated in most cases with transurethral or open resection. The prognosis of this tumor is excellent and no malignant degeneration has been reported. The most common presentations are obstructive voiding symptoms, irritative symptoms, and hematuria. Occasionally, it may be a cause of urinary stress incontinence. Although this condition is rare, it should be considered in the causes of urinary stress incontinence.- - - - - - - - - - ranking = 1keywords = physical (Clic here for more details about this article) |
6/17. Inflammatory processes mimicking bladder tumors in children.Tumor-like proliferative lesions were discovered on cystourethrography and cystoscopy in two children, one with severe bacterial urinary tract infection and the other with painless terminal hematuria. Histologically, these lesions were characterized by inflammatory infiltration and proliferative changes of the bladder epithelium. Appropriate treatment, including antibiotics, resulted in complete disappearance of the bladder lesions in both patients. The development of such lesions is related to the potential for nonneoplastic proliferation and metaplasia of the bladder epithelium and is considered to be the result of irritation associated with infection or other chemical and physical factors. The known malignant potential of such bladder pathology indicates a need for careful, long-term follow-up in such patients, including children.- - - - - - - - - - ranking = 1keywords = physical (Clic here for more details about this article) |
7/17. recurrence of vaginal implantation of transitional cell carcinoma of the urinary tract.BACKGROUND: Vaginal recurrence of bladder carcinoma is extremely rare, with only two cases already reported. We have experienced a third case with the same characteristics of the first one, which was a vaginal recurrence with a prior resected urothelial vaginal tumor. CASE: An 82-year-old woman first presented in 1994 with frequency and gross hematuria. Cystoscopic evaluation revealed a single superficial tumor of the bladder which was treated by endoscopic resection. During the following 7 years, she underwent endoscopic procedures to remove recurrent Ta G2 tumor. In 2002, a cystoscopy revealed a papillary lesion, and a physical examination demonstrated multiple papillary lesion on the vaginal wall. histology of excised genital lesions showed a Grade 2 transitional cell carcinoma. Two years later, the patient presented with a 1-cm solitary lesion on the right vaginal wall, which was then excised. Histological examination showed high-grade transitional cell carcinoma, infiltrating the chorion of the vagina. CONCLUSION: Implantation of shed tumor cells in tissues during micturition or resection seems the only plausible cause of the first implantation. For the second recurrence in the vagina, the possibility is of an incomplete locally excision or a relapse, tied to lymphatic micro metastasis, due to involvement of its own lamina propia.- - - - - - - - - - ranking = 10.81005289251keywords = physical examination, physical (Clic here for more details about this article) |
8/17. polyomavirus infection versus high-grade bladder carcinoma. The importance of cytologic and comparative morphometric studies of plastic-embedded voided urine sediments.The cytodiagnostic criteria of polyomavirus infection of the urinary tract versus high-grade bladder carcinoma in Cytospin and plastic-embedded preparations of voided urine samples are presented. In Cytospin preparations, the polyomavirus infection and the high-grade bladder carcinoma could not always be distinguished from each other. The diagnosis was facilitated when plastic-embedded specimens were used for cytologic study. On the basis of the comparison of morphometric data from the two types of specimens, it is postulated that the physical properties of the cancer cell nuclei differ from those of the virocytes.- - - - - - - - - - ranking = 1keywords = physical (Clic here for more details about this article) |
9/17. Humoral hypercalcemia of malignancy. Release of a prostaglandin-stimulating bone-resorbing factor in vitro by human transitional-cell carcinoma cells.Secretion by tumor cells of circulating bone-resorbing factors may frequently underlie the hypercalcemia that occurs in patients with malignancy. Efforts to identify the responsible mediators have been hampered by a lack of available human tumor cell systems suitable for study of the pathogenesis of the humoral hypercalcemia syndrome. We have established a transitional-cell carcinoma (TCC) line in vitro from a patient with humoral hypercalcemia. These cells are tumorigenic and cause hypercalcemia in athymic nude mice. culture medium conditioned by TCC cells contains potent bone-resorbing activity in vitro, the physical and biological properties of which are similar to those of bone-resorbing activity present in the original patient's urine. The bone-resorbing activity of the TCC factor is accompanied by increased prostaglandin release from bone and is blocked by indomethacin and calcitonin. The TCC-derived bone-resorbing activity coelutes with prostaglandin-stimulating activity during gel filtration with an approximate molecular weight of 15,000. This activity is nondialyzable, stable to concentrated urea and reducing agents, and destroyed by boiling. The TCC factor does not increase cyclic amp production in bone or kidney bioassays and does not exhibit transforming growth factor activity. We conclude that a unique macromolecular factor released by TCC cells causes bone resorption by a mechanism dependent upon stimulation of bone cell cyclooxygenase, and that this factor is the probable cause of the hypercalcemia in vivo. The TCC cell line provides a new model for study of the human humoral hypercalcemia syndrome.- - - - - - - - - - ranking = 1keywords = physical (Clic here for more details about this article) |
10/17. Bladder carcinoma presenting as exercise-induced hematuria.exercise-induced hematuria is becoming a common diagnosis for postexercise hematuria. However, a number of genitourinary tract diseases also may cause gross or microscopic hematuria in some physically active patients. Four cases of postexercise hematuria in patients with transitional cell carcinoma of the bladder are presented. The authors recommend urologic evaluation with excretory urography and cystoscopy for all patients with postexercise hematuria.- - - - - - - - - - ranking = 1keywords = physical (Clic here for more details about this article) |
