Questionnaire survey on female urinary frequency and incontinence

BACKGROUND: Urinary incontinence is a well-known bothersome symptom in women, which may cause physical and psychological problems. We conducted a questionnaire survey on female urinary incontinence to investigate the disease's impact on the quality of life (QoL), the reasons women don't seek medical attention and the information they wished to obtain. PATIENTS AND METHODS: From March to October 2002, a member of the Professional Women's Coalition for Sexuality and Health distributed a questionnaire about urinary frequency and urinary incontinence to women who were attending the lectures hosted by the group. RESULTS: We analysed 262 questionnaires: 158 people belonged to the Stress Urinary Incontinence (SUI) Group, 36 to the Overactive Bladder (OAB) Group, 22 to the Urinary Frequency (UF) Group and 18 to the Normal Group. 'Going out' was most influenced in all three groups with symptoms in their daily life. Compared with the Normal or SUI Group, the QoL in those belonging to the OAB and UF Groups was more deteriorated. The medical institution check-up rate in the SUI Group was the lowest at 7.1%, bringing down the overall consultation rate to 13.5%. More than 70% of respondents who didn't have a check-up said that they did not think it was a problem serious enough to require consultation. CONCLUSIONS: Urinary incontinence and frequency impairs women's QoL. It is important to provide information on these diseases and to provide medical treatments that cater to the needs of individual patients.     

Influence of thrombopoietin on platelet activation in myeloproliferative disorders

Although thrombopoietin itself does not influence platelet aggregation, it enhances platelet activation in response to certain agonists. We evaluated the effects of thrombopoietin on platelet activation using platelet-rich plasma from 16 patients with myeloproliferative disorders (MPD group) and 16 healthy volunteers (control group). Preincubation with thrombopoietin significantly enhanced platelet aggregation stimulated by ADP, collagen, or epinephrine in the MPD group as well as the control group. However, aggregation induced by 3 μ M ADP or 16 μ M epinephrine showed significantly less augmentation by thrombopoietin in the MPD group than in the control group. Thrombopoietin significantly shortened the lag time between the addition of 3 μ M ADP or 16 μ M epinephrine and initiation of secondary aggregation and the lag time between addition of 2 μg/ml collagen and initiation of aggregation in both groups. When platelet-rich plasma was used without adjustment of the platelet count, thrombopoietin itself induced aggregation in two patients. Hypoaggregation after addition of 0.5 μg/ml collagen was observed in seven out of nine patients with normal thrombopoietin levels and only one of six patients with high levels ( P =0.04). Enhancement of 0.5 μg/ml collagen-induced aggregation by thrombopoietin was seen in five out of nine patients with normal thrombopoietin levels and none of the six patients with elevated levels ( P =0.04). These results indicate that platelet activation by certain agonists is enhanced by thrombopoietin in patients with these diseases as well as in normal controls and that the serum thrombopoietin level may regulate the function of circulating platelets in vivo .     

Granulocyte-colony stimulating factor-induced proliferation of primary adult T-cell leukaemia cells

Granulocyte-colony stimulating factor (G-CSF) is known to induce proliferation and differentiation of granulocyte progenitors, and is widely used to treat neutropenia induced by intensive chemotherapy for malignant lymphoma or adult T-cell leukaemia/lymphoma (ATL). G-CSF is thought not to stimulate malignant lymphoid cells. In the present study we examined the ability of G-CSF to induce in vitro growth of primary ATL cells from 14 patients (nine acute-type, two chronic-type and three lymphoma-type), and we analysed the in vivo counts of ATL cells in patients who received G-CSF for neutropenia. FACS analysis using phycoerythrin-labelled recombinant G-CSF demonstrated that ATL cells from 11/14 patients express some G-CSF receptor (G-CSFR), with a range between 5.4% and 87.3%. Cells expressing G-CSFR also expressed CD4. Reverse polymerase chain reaction (PCR) analysis demonstrated expression of G-CSFR messenger RNA in G-CSFR expressing cells. Leukaemic cells derived from seven (four acute-type, one chronic-type and two lymphoma-type) of the 14 patients proliferated in vitro in response to G-CSF, as measured by [³H]thymidine incorporation; maximum responses were at G-CSF concentrations of 10–100 ng/ml. Nine of 14 patients receiving rG-CSF for neutropenia were analysed retrospectively for ATL cell numbers. Four patients whose primary tumour cells proliferated in response to rG-CSF in vitro showed a significant increase in ATL cell count after administration of rG-CSF ( P  =0.038), whereas five patients whose leukaemic cells did not proliferate in vitro showed no significant increase in ATL cell count. G-CSF can stimulate proliferation of ATL cells which may complicate therapy for this disease.     

Superficial Siderosis of the Central Nervous System Caused by Hemorrhagic Intraventricular Craniopharyngioma: Case Report and Literature Review

Superficial siderosis is a rare condition caused by hemosiderin deposits in the central nervous system (CNS) due to prolonged or recurrent low-grade bleeding into the cerebrospinal fluid (CSF). CNS tumor could be one of the sources of bleeding, both pre- and postoperatively. We report an extremely rare case of superficial siderosis associated with purely third ventricle craniopharyngioma, and review previously reported cases of superficial siderosis associated with CNS tumor. A 69-year-old man presented with headache, unsteady gait, blurred vision, and progressive hearing loss. Brain magnetic resonance (MR) imaging with gadolinium revealed a well enhanced, intraventricular mass in the anterior part of the third ventricle. T₂*-weighted gradient echo (GE) MR imaging revealed a hypointense rim around the brain particularly marked within the depth of the sulci. Superficial siderosis was diagnosed based on these findings. The tumor was diffusely hypointense on T₂*-weighted GE imaging, indicating intratumoral hemorrhage. The lateral ventricles were dilated, suggesting hydrocephalus. [¹⁸F]fluorodeoxyglucose positron emission tomography revealed increased uptake in the tumor. The whole brain surface appeared dark ocher at surgery. Histological examination showed the hemorrhagic tumor was papillary craniopharyngioma. His hearing loss progressed after removal of the tumor. T₂*-weighted GE MR imaging demonstrated not only superficial siderosis but also diffuse intratumoral hemorrhage in the tumor. Superficial siderosis and its related symptoms, including hearing loss, should be considered in patients with hemorrhagic tumor related to the CSF space. Purely third ventricle craniopharyngioma rarely has hemorrhagic character, which could cause superficial siderosis and progressive hearing loss.     

An acquired bullous dermatosis due to an autoimmune reaction against uncein

Summary A 59-year-old male showed acquired. mechanically induced, scarring blisters on the fingers, toes, scalp and abdomen, as well as in the oral cavity. Ultrastructural and immunohistochemical examination of the bullae revealed junctional epidermal-dermal separation and lgG deposits in the lamina lucida of the basement membrane zone (BMZ). where the reactivity of the 19-DKJ-1 monoclonal antibody was decreased. Anti-BMZ autoantibodies detected in his serum were reactive to the lower lamina lacida region of normal human skin. SDS-PAGE of affinity purified antigens from human keratinocytes with IgG from the patient's serum revealed three polypeptide bands at 165, 135 and 1OO kDa. in reduced condition. The indirect immunofluorescence test of his serum was negative on skin cryosections from patients with lethal junctional epidermolysis bullosa. Pretreatment of normal human skin sections with the patient's serum, blocked the binding of 19-DEJ-1 monoclonal antibody but not that of the GB3 monoclonal antibody. This case is considered to be an acquired autoimmune bullous dermatosis due to an autoantibody reaction against uncein (19-DEJ-1 antigen). a component of anchoring filaments.     

Transitional cell carcinoma of the navicular fossa detected human papillomavirus 16

We present a rare case of transitional cell carcinoma of the navicular fossa in an elderly man. We detected the expression of human papillomavirus type 16 specific DNA sequence in the tumor using polymerase chain reaction. Human papillomavirus dissemination into the urethra by urethral instrumentation might cause urethral tumors, such as squamous cell carcinoma or condyloma acuminatum, and also transitional cell carcinoma as seen in the present case.     

Impact of radical perineal prostatectomy on urinary continence and quality of life: A longitudinal study of Japanese patients

AIM: We used self-completed questionnaires to obtain a longitudinal assessment of urinary continence and urinary, bowel, and sexual domain-related quality of life (QOL) in Japanese patients undergoing radical perineal prostatectomy (RPP). METHODS: A total of 41 Japanese patients with a median age of 69 years who underwent RPP between February 2002 and February 2004 were included in the study. We measured QOL by the University of California, Los Angeles, Prostate Cancer Index (UCLA-PCI) and assessed urinary continence on the basis of three different definitions of continence. The International Prostate Symptom Score (I-PSS) was also included to evaluate lower urinary tract symptoms (LUTS). RESULTS: When urinary continence was de fi ned as none, one, or two protective pads per day, 100%, 73%, 94%, 97%, or 100% of the patients were continent before, and 1, 3, 6, and 12 months after, RPP, respectively. When it was de fi ned as total control or occasional dribbling, the corresponding values were 97%, 70%, 84%, 94%, and 97%. Urinary function returned to the preoperative baseline level by 6 months postoperatively and scores for urinary bother had significantly surpassed the baseline by 12 months (P = 0.043). The I-PSS was significantly improved (P = 0.014), with a mean 4.7-unit decrease. Sexual function worsened significantly after surgery, and its recovery was less favorable. No significant change was observed in scores for bowel function or bowel bother. CONCLUSIONS: The majority of patients who undergo RPP rapidly regain urinary continence and QOL within 3-6 months. RPP has a favorable impact on LUTS.
