In a woman aged 80 years arriving in the Emergency Room with progressive malaise, anorexia and somnolence, a large resistance was found in the lower abdomen, which proved to be due to cystitis emphysematosa. The patient was known to suffer from non-insulin dependent diabetes mellitus. Imaging revealed a large accumulation of gas in the urinary bladder, which was treated successfully with catheterization and antibiotics. Cystitis emphysematosa is a rare condition, characterized by collection of gas in the bladder and bladder wall and brought about by gas-forming micro-organisms that decompose glucose. In patients with diabetes mellitus optimal regulation of the blood glucose levels, with a view to preventing glycosuria, is a condition of speedy recovery. Although cases with a fatal outcome have been reported, the prognosis in general is favourable.

ZD7114, [(S)-4-[2-(2-hydroxy-3 phenoxypropylamine)ethoxy]-N-(2-methoxyethyl) phenoxyacetamide], and ZD2079, [(R)-N-(2-[4- (carboxymethyl)phenoxy]ethyl)-N-(beta-hydroxyphenethyl)ammonium chloride], are beta 3-adrenoceptor stimulants with selectivity for brown adipose tissue. ZD7144 is the hydrochloride salt of the S-enantiomer of the racemic amide ZD2079. They were developed as potential novel treatments for obesity and non-insulin-dependent diabetes mellitus. Male and female rats were dosed separately by gavage for a minimum of 28 days with 0, 10, 50, and 500 mg/kg/day of ZD7114 or with 0, 10, 30, and 150 mg/kg/day of ZD2079. Two further groups of male and female rats were dosed with 0 and 500 mg/kg/day of ZD7114 for 28 days and were then allowed a 6-wk, undosed withdrawal period. At high doses, both compounds caused urinary tract toxicity, which primarily affected the distal tubules and collecting ducts of the kidney via tubular necrosis. They also caused ureteric inflammation, cystitis, and accumulation of crystalline inclusions throughout the urinary tract. As a result of urinary tract toxicity, affected animals from one or both studies showed reduced red blood cell indices, lower platelet counts, and higher white cell counts. Blood chemistry revealed lower plasma concentrations of glucose (7.28 +/- 1.37 compared to 8.11 +/- 0.65 for the control) and total protein (63.42 +/- 3.65 compared to 69.17 +/- 3.24 for the control) and increased plasma urea (37.15 +/- 19.96 compared to 8.09 +/- 0.87 for the control). Urinalysis showed an increase in the number of crystals, blood, and protein. In the urinary tract, the severe crystalluria with accumulation of crystalline material indicated that this may have a role in the etiology of the target organ toxicity. Poor solubility of the compounds at normal urinary pH was considered a possible mechanism for the crystalluria.

Alkylating drugs (cyclophosphamide and ifosfamide) have been in clinical use for the treatment of malignant diseases in the past. They are most useful anticancer agents and cyclophosphamide is also widely used for its immunosuppressive properties. However the effect of alkylating drugs on thyroid hormone parameters have not been evaluated so far. Three groups of patients were prospectively evaluated: Group I: 15 patients with Wegener's granulomatosis and 4 patients with severe scleritis received a single dose cyclophosphamide (15 mg/kg bw/day) and 250 mg prednisone i.v. Group II: 9 patients with malignant lymphomas were treated according to the IMVP 16-protocol. Patients received daily ifosfamide 1000 mg/m2 from day 0 to 4 and vepesid from day 0 to 2. Patients did not receive corticosteroids additionally. Group III: 6 patients with a relapse of malignant lymphomas received ifosfamide 1.500 mg/m2/day from day 0 to 4 i.v. and dexamethasone 40 mg/m2 as well as ara-c and etoposid. All patients received mesna to prevent hemorrhagic cystitis and odansetran or metoclopramide as antiemetic drugs. Alkylating drugs were given as a one hour infusion. Thyroid hormone parameters were determined before and on day 1, 2, 3, 4 after drug administration. We observed a significant increase in T4 and fT4 concentrations and a concomitant fall in TSH in either group one day after the administration of alkylating drugs. The effect was most pronounced in group III: T4 increased from 113 +/- 8 nmol/L to 175 +/- 8 (normal: 58-154) and fT4 from 14.0 +/- 0.8 to 24.8 +/- 2.5 pmol/L (normal 10-25). TSH dropped from 1.27 +/- 0.16 to 0.33 +/- 0.07 mU/L (normal 0.3-4). All changes were significant: p < 0.001. Two of the six patients displayed biochemical hyperthyroidism. Also reverse T3 increased significantly. Two days after drug administration a gradual normalization occurred. However, T3, Tg, TBG, Transthyretin and albumin levels did not change throughout the study period. One patient with coexisting hypothyroidism, who received his last thyroxine substitution therapy one day before the administration of cyclophosphamide (as in group I), also demonstrated an increase in T4, fT4 and rT3 and a fall in TSH concentrations. I.v. administrations of cyclophosphamide and ifosfamide induce a transient increase in T4 and fT4 concentrations and a concomitant fall of TSH in the presence of normal Tg, T3 and thyroid binding protein concentrations. These data suggest, that the changes are not due to a release of thyroid hormones from the thyroid itself, but is likewise related to a release of thyroxine from cellular pools such as the liver.

A 74-year-old woman with diabetes mellitus had a high fever, and was treated with antibiotics and insulin in another hospital. She was referred to our department, because CT scan showed the right hydronephrosis and the abnormal gas shadow in the right renal calyces. Ureteral catheterization was performed on the right side and cloudy urine was drained. Urine culture yielded E. coli. Since submucosal emphysematous changes were demonstrated in the bladder mucosa by cystoscopy, she was diagnosed with emphysematous pyelonephritis with emphysematous cystitis associated with diabetes mellitus. Administration of antibiotics and insulin and the ureteral catheter drainage improved her condition immediately. Abnormal gas shadow on CT scan and submucosal emphysema on cystoscopy disappeared. We reviewed 110 cases of emphysematous pyelonephritis and 23 cases of emphysematous cystitis including our case in Japan, and report their clinical characteristics.

Detachment of glomerular epithelial cells (GEC) from glomerular basement membrane (GBM) could account for a part of the pathogenic mechanism of proteinuria seen in primary and secondary renal diseases. The Wilms' tumour suppresser gene (WT1) is strictly expressed in GEC in the adult kidney. Mutations of WT1 gene have been implicated in progressive renal damage. Utilizing nested RT-PCR we detected mRNA of WT1 in the urine of patients with renal diseases. Seven of 20 (35%) chronic glomerulonephritis (CGN), eight of 20 (40%) diabetes mellitus (DM) with proteinuria, and two of 24 (8.3%) rheumatic diseases were WT1 positive. Interestingly, only one of 51 (2%) DM without proteinuria was WT1 positive. None of the healthy volunteers or cystitis patients were WT1 positive. This is the first report describing the detection of endogenous WT1 mRNA, an important gene in progressive renal failure, from patients' urine. This technique could be a powerful tool in the search for information about glomerular damage in clinical settings as well as for WT1 mutations or isoform imbalance at the research level without renal biopsy.

Emphysematous cystitis (EC) is a rare condition in which gas-forming organisms are active in the bladder wall and lumen. Most of the cases have been described in patients suffering from diabetes mellitus due to glucosuria and subsequent anaerobic fermentation of glucose. To our knowledge this condition has never been described in association with systemic lupus erythematosus (SLE). We report here the first case of EC during the course of a chronic lupus cystitis (LC) in a woman suffering from SLE and type-I diabetes mellitus.

A study was made of a 55 years old male, who suffered from emphysematous cystitis with diabetes mellitus. He had multiple complications due to diabetic neuropathy such as foot ulceration, oculomotor nerve palsy, peroneal nerve palsy and a neurogenic bladder. Klebsiella pneumoniae and Pseudomonous aeruginosa were cultured from urine specimens. There have been only 19 reported cases of emphysematous cystitis since 1962. Fourteen of these cases had diabetes mellitus.

Using the UBC test, the specificity, sensitivity and prognostic information were evaluated in patients with recently diagnosed transitional cell carcinoma (TCC) and in a control group consisting of apparently healthy individuals and individuals with benign disorders. Frozen urine samples from the 485 individuals in the control group and 100 newly diagnosed TCC patients were analyzed with the UBC test, specific for epitopes on cytokeratin fragments released from the urothelial cells. All the samples were analyzed and corrected for creatinine. No significant concentration difference was found between males and females (p=0.65) and there was no age dependent relation. The median concentration for the entire control group was estimated at 3.7 microg/g and the 95th percentile was calculated at 53.0 microg/g. The apparently healthy individuals in the control group had a median value of 3.4 microg/g with a 95th percentile of 24.3 microg/g. An increased frequency of elevated UBC concentrations was found in some benign disorders e.g., anemia, thyroid disorders, diabetes mellitus, hyperlipemia, urosepsis and cystitis. Patients with superficial tumors exhibited a 66% sensitivity (at 95% specificity), and the UBC concentrations did not differ statistically (p=0.16) from those patients with muscle invasive lesions with a 52% sensitivity. When the UBC concentrations were related to histopathological grade, a significant concentration difference (p<0.004) was found between low grade tumors (sensitivity 41%) and high grade tumors (sensitivity 72%). Survival analysis showed that patient with muscle invasive tumors, high-grade tumors and high UBC concentrations have a significantly reduced survival (five-year survival was estimated to 30%, 35% and 30% respectively) compared to patients with superficial tumors, low-grade tumors or low UBC concentrations (five-year survival, 60%, 85% and 75% respectively). The UBC test showed good accuracy and repeatability. Clinically the test could assist in tumor grading and the detection of recurrent disease, which in turn could assist in treatment selection for the individual patient and possibly improve prognosis.

We describe the case of a 72-year-old woman who displayed massive multiple intramural gas collections of the bladder wall as an incidental finding on CT. The patient presented with critical ischemia of the left leg caused by paradoxical arterial embolism, raised corpuscular sedimentation rate, anemia by gastrointestinal blood loss, hypoproteinemia, diarrhea, malabsorption, and exudative enteropathia caused by mycobacterial ileocolitis. The patient had no dysuria and there was no evidence of diabetes. The intramural gas collections of the bladder wall, as shown by CT, were compatible with emphysematous cystitis. Urine samples proved infection by a multi-resistant strain of E. coli. Emphysematous cystitis is a rare form of bladder infection that can be diagnosed by plain-film radiograms or CT.

Urinary tract infections (UTIs) are the most common infections seen in the hospital setting, and the second most common infections seen in the general population. Due to women's anatomy, UTIs are especially problematic for them, and up to one-third of all women will experience a UTI at some point during their lifetimes. Appropriate treatment of a UTI requires accurate classification that includes infection site, complexity of the infection, and the likelihood of recurrence. The predominant pathogen in both complicated and uncomplicated UTI remains pathogenic Escherichia coli, although Klebsiella sp. and Proteus appear with increased frequency in complicated UTI. Most often, bacteria cause UTIs by ascending means through the urethra into the bladder. Bacteria must possess virulence factors to cause UTI. Host defense factors that predispose patients to UTI include urinary stasis, abnormal urinary tract anatomy, diabetes mellitus, debility, and aging. Estrogen-related issues and short urethras predispose women to UTI. Although urine culture, with >105 colony-forming units/mL (CFU/mL) in symptomatic patients, remains the diagnostic "gold standard," correlation of the patient's history and physical examination with urinalysis (including nitrite dipstick and leukocyte esterase test) results usually suffices to diagnose UTI. Three-day of antimicrobial treatment is recommended for simple cystitis. Acute pyelonephritis, an infection of the kidney parenchyma tissue, is treated with antibiotics for 7 to 14 days depending on the antimicrobial agent used and the severity of infection. In addition, patient classification determines the need for hospitalization or for urological imaging studies. Women with recurrent UTIs merit consideration for antimicrobial prophylaxis. Self-administered topical vaginal estradiol cream is an important adjunct in UTI prevention for postmenopausal women. Asymptomatic bacteruria only merits antimicrobial therapy in high-risk patients or those colonized with Proteus species.
