Objective: To analyze the lower urinary tract symptoms (LUTS) and video‐urodynamic characteristics of women with clinically unsuspected bladder outlet obstruction (BOO). Methods: From 1997 to 2010, a total of 1605 women with bothersome LUTS received video‐urodynamic study in our unit. We reviewed the charts of 212 women diagnosed with BOO based on video‐urodynamic criteria and 264 women without abnormal findings. LUTS and urodynamic parameters were compared between obstructed and unobstructed cases and among the BOO subgroups. Results: The mean ages of the BOO (58.2 years) and control groups (58.8 years) were similar. The mean values of detrusor pressure at maximum urinary flow rate (PdetQmax)/maximum flow rate (Qmax) of the BOO and control groups were 51.83 cm H2O/10.22 mL/s versus 18.81 cm H2O/20.52 mL/s. In the BOO group, cinefluoroscopy revealed dysfunctional voiding in 168 patients (79.2%), urethral stricture in 17 (8.0%), and bladder neck dysfunction in 27 (12.7%). Patients with dysfunctional voiding had significantly lower urethral resistance compared with the other two BOO subgroups. Combined lower urinary tract symptoms were present most often in all BOO patients (69.3%), followed by isolated storage symptoms (30.2%) and isolated voiding symptoms (0.5%). Seventy‐seven patients (37.3%) had dysuria and 79 patients (36.3%) had frequency as their main symptom. Conclusion: Women with BOO usually have nonspecific LUTS. Dysfunctional voiding was the most common form among women with clinically unsuspected BOO, but the degree of obstruction was less severe than with primary bladder neck obstruction and urethral stricture. 相似文献

House dust mites are widely recognized as major factors involved in the triggering of allergic diseases such as asthma. It is now apparent that the group III allergens of the Dermatophagoides mite species may play a significant role in a number of house dust mite allergic cases. Natural Der p III was isolated by gel filtration of salt precipitated Dermatophagoides pteronyssinus extract and as reported previously ran as a doublet of Mr 28 and 30 K on sodium dodecyl sulphate-polyacrylamide gel electrophoresis (SDS-PAGE). Natural Der fIII was isolated by affinity purification with the 5A12 monoclonal antibody. Amino acid sequence data was generated for both these proteins which was used to construct DNA probes to screen a Dermatophagoides pteronyssinus cDNA library by hybridization and resulted in the isolation of a recombinant Der p III cDNA clone, P3WSI. The 1059 bp cDNA fragment included a 786 bp open reading frame which encodes a pre-pro region of 29 amino acids and a mature protein of 232 amino acids with a calculated Mr 24985. A search of the BLAST protein database has confirmed that the Der p III P3WS1 clone is approximately 50% homologous with other trypsin proteins. We have confirmed with both our natural protein sequence and the P3WS1 amino acid sequence data that the group III allergens are trypsin-like proteins. 相似文献

A 25-year-old man presented with several prominent subcutaneous masses in the occipital region of the scalp. He had a long history of tinea capitis and tinea corporis infection. Histopathology of the occipital lesions showed mycelial aggregates in the deep dermis and subcutis. Cultures of the excised material and superficial scales grew a fungus identified as Microsporum ferrugineum. We propose the term ‘dermatophyte pseudomycetoma’ to describe this distinctive mycosis. 相似文献

Using His bundle electrograms and programmed ventricular stimulation, the effects of chronic amiodarone treatment on induction, morphology, and the rate of ventricular tachycardia (VT) were studied in 17 consecutive patients treated with amiodarone for control of recurrent sustained VT or ventricular fibrilation. Studies were done before and after treatment with amiodarone for an average duration of 5.3 (range 2 to 18) months. During the control study, sustained VT could be induced in 16 patients. VT was initiated by single or double right ventricular (RV) extrastimuli in 14 patients, by double left ventricular (LV) extrastimuli in 1 patient, and by RV burst pacing in 1 patient. Only one pattern (morphology) of VT similar to that of spontaneous VT was induced in 12 patients and two patterns of VT in 4 patients. The average cycle length (CL) (mean ± SD) of induced VT was 325.8 ± 61.2 ms. After amiodarone, VT could be induced in 7 of 17 patients and was initiated by single RV extrastimuli in 5 patients, double RV extrastimuli in 1 patient, and RV burst pacing in 1 patient. In 3 of 5 patients in whom VT could be initiated by single RV extrastimuli, initiation of VT required double RV or double LV extrastimuli in the control study; in 1 of 5 patients VT could not be induced in the control study. Amiodarone induced nonclinical, polymorphic VT in 4 patients in whom only clinical VT could be induced during the control study. Compared to control, the CL of induced VT was significantly longer (322 ± 65.7 vs 416 ± 41.5 ms; P < 0.001). During a follow-up period ranging from 4 to 53 (mean ± SD; 18.6 ± 11.4) months, VT did not recur in 8 patients with no inducible VT and in 6 patients with persistence of inducible VT. One patient without inducible VT died suddenly; VT recurred in 2 patients, one without inducible VT and one with inducible VT. The results show that programmed stimulation studies late in the course of treatment do not accurately reflect the clinical efficacy of amiodarone in VT. 相似文献
