[Vaginal reflux during miction-cystourethrography in girls (author's transl)].

The cases of 57 girls with reflux of radioopaque iodin solution into the vagina during mictioncystourethrography are reported. In 52.6% (30 cases) no signs of anomalies of the urinary tract or of pyelonephritis were found. For this group of 30 girls pyuria (leucocyturia) was typical (in 86.6%). In contrast, a urinarty-tract infection was found only in a few cases (16.6%). The authors discuss the clinical importance of vaginal reflux and its role in the pathogenesis of urinary-tract infections.

[Urinary tract infections in premature infants: considerations on the reliability of bladder catheterization and other methods of urine collection for bacteriological study].

The collection of urine by the use of adhesive plastic bags even if simple is not unfailing procedure for making diagnosis of urinary tract infection (U.T.I.) because of contamination with bacteria located on the external genitals. This is particularly true in the case of the premature baby. Therefore this method of urine's collection has been considered not enough satisfactory in symptomless cases since an early diagnosis of U.T.I. in this premature babies is extremely important. The Authors suggest that after a first positive test response by urine's collection with adhesive plastic bags is extremely important to collect the urine with a catheter specimen in the females and with sterile test tube in the males. Using these criteria, satisfactory results have been obtained. To prevent possible bladder urine contamination by catheter use, antibiotic treatment had been applied for few days after specimen collection. The non catheter specimen collection of the urine remains of course, one of the most important test to detect pyuria during U.T.I.

The microbial flora of the urogenital tract in women with symptoms of recurrent urinary tract infection. The non-influence of methenaminehippurate treatment on the idigenous flora.

Recurrent urinary tract infections are known to occur among 5 per cent of all females. These women frequently have episodes of symptoms of lower urinary tract infection even between periods of bacteriuria. In the present study, 25 women with a history of recurrent urinary tract infections, found to lack signs of obstructive uropathy, were subjected to an extensive urological and microbiological survey. The investigation showed that (i) "pyuria" was common (9/12) but usually of urethral origin, (ii) introital and/or urethral colonization with Enterobacteriaceae often (11/25) occurred, (iii) apart from Escherichia coli found in three patients, a Bacteroides species was isolated in two and ureaplasmas in one patient from suprapubically aspirated urine, and (iv) chlamydia, gonococci, and trichomonads were not found. The patients were given methenaminehippurate for 1 week and then reexamined. The treatment did not seem to influence the indigenous flora of the lower urogenital tract.

Fistulas of the bladder in Crohn's disease.

Fourteen patients with fistulas of the bladder complicating Crohn's disease are reported. In one-half of the patients, the presence of Crohn's disease was known before; in the other one-half, the appearance of urinary symptoms led to the diagnosis of Crohn's disease. The symptom most commonly encountered was chronic pyuria, while pneumaturia as an early sign was found in only three patients. Cystoscopy proved to be the most useful diagnostic procedure. The results of this examination demonstrated lesions in 11 of 13 patients investigated and was instrumental in arriving at the correct diagnosis in four patients. Treatment should be surgical and consist of intestinal resection and suturing of the usually small defect in the bladder. The results of the operation are good with respect to the complication of the urinary tract.

[Acute hemorrhagic leucoencephalitis during tuberculosis (author's transl)].

The authors report a fairly typical clinico-pathological case of acute hemorragic leucoencephalitis (A.H.L.E.). Both clinical and histological features appeared particularly acute. At autopsy a visceral evolving tuberculosis was diagnosed. Such an etiological circumstance has not been, apparently, reported in cases of A.H.L.E. published as such. Three other etiological circumstances were noticed: pyuria, treatment by cephalotin and treatment by gentamycine. The physiopathogenesis of A.H.L.E. remains obscure and will not be clarified before detailed immunological studies can be performed. But the disease is rare and brisk and diagnosis usually post-mortem.

Granulomatous sarcoid nephritis: a cause of multiple renal tubular abnormalities.

We report the eleventh case of granulomatous sarcoid nephritis and review the previous literature. Although not as commonly recognized as calcium nephropath, granulomatous nephritis may be an important cause of morbidity and mortality in patients with sarcoidosis. Its characteristics are similar to other tubulo-interstitial diseases. Mild to moderate albuminuria, microscopic hematuria and sterile pyuria predominate. Hypertension is usually absent and renal size is well preserved. Urinary concentration defects (including nephrogenic diabetes insipidus), renal tubular acidosis and inappropriate glucosuria may also be seen. Interstitial inflammation with non-caseating granulomas, epithelioid and multinucleated giant cells is the usual histologic picture. Intimal thickening is not infrequent and granulomas may occasionally involve the small arteries. Immunofluorescence and electron microscopic findings are non-specific.

Eosinophils in urine revisited.

The finding of eosinophils in the urine has been suggested to be useful in establishing the diagnosis of acute interstitial nephritis (AIN). The diagnostic accuracy of this test has not yet been defined. It is the purpose of this study to define the specificity, sensitivity, and the predictive positive and negative values for the presence of eosinophils in the urine. One hundred forty-eight patients with pyuria were tested for the presence or absence of urinary eosinophils. In this group consecutively admitted to the hospital with WBC in the urine, 4% of patients had urinary eosinophilia of greater than 1 eosinophil per 100 cells. Since none of this group had the diagnosis of AIN, the false positive rate was 4% and the specificity was 96%. In a selected group of patients in which the diagnosis of AIN was suspected by a nephrology consultant, urinary eosinophils were found in 6 of 15 patients with a confirmed diagnosis of AIN but were also found in 10 of 36 patients with another renal diagnosis. The sensitivity for eosinophiluria was 40% and the specificity was 72% with a positive predictive value of only 38%. We conclude that eosinophiluria is not an accurate test for the diagnosis of AIN. The false positive and negative rates are too high to confirm an AIN diagnosis.

Urological abnormalities in 1,328 patients with nocturnal enuresis.

OBJECTIVES: Evaluation of the incidence of urological abnormalities as revealed by urological examinations of a large number of patients with enuresis. METHODS: Patients with the chief complaint of nocturnal enuresis were examined urologically. RESULTS: The incidence of urological abnormalities was 1.8% of 940 patients on intravenous pyelography (IVP), 7.1% of 695 patients on voiding cystourethrography (VCG) and 11.5% of 487 patients on cystometry (CM). No abnormal findings were observed in 58 patients on renal ultrasonography (US). 92.1% of reflux cases detected by VCG were low grade and only 8.9% of patients with reflux had pyuria. 20.2% of 446 patients who were submitted to all these examinations had some urological abnormality. Only pollakisuria was statistically more frequent in patients with urological abnormalities than in patients without them. CONCLUSION: These data suggest that the incidence of urological abnormalities was rather low when compared with the past literature. In particular, IVP was though to be unnecessary.

[Fluconazole in treatment of urinary candidiasis. Experience with 24 patients].

Since fluconazole achieves high urine concentrations, we assessed its usefulness in the treatment of urinary candidiasis. We studied 24 patients (8 male) aged 23 to 97 years old, that presented pyuria with a negative urine culture for bacteria and fungal colony counts in urine of 10(4) CFU/ml or more. Isolated strains were Candida albicans in 20 cases, Candida kefyr in one case, Candida glabrata in one case and Candida spp in two cases. All patients were treated with fluconazole in doses of 50 to 100 mg/day for 2 to 4 weeks. The fungus was eradicated in 21 patients (88%), the infection persisted in two (8.5%) and one had a relapse (4.2%). Two patients had transient elevations of transaminases, one had abdominal pain and one, a purpuric syndrome without thrombocytopenia in whom the drug was discontinued. It is concluded that fluconazole is efficacious and safe in the treatment of urinary candidiasis.

Abnormalities of urinary sediment and renal failure following sulfinpyrazone therapy.

A patient with recurrent thrompophlebitis had sterile pyuria with white blood cell casts and transient, mild renal failure during therapy with sulfinpyrazone. These abnormalities resolved on cessation of therapy, but similar changes in the urinary sediment recurred during therapy with sulfinpyrazone. These abnormalities resolved on cessation of therapy, but similar changes in the urinary sediment recurred during a second course of sulfinpyrazone therapy.

[Pathological horseshoe kidney. 30 case reports].

The authors report a series of 30 horseshoe kidneys observed over a 20-year period. This series consisted of 20 men (66.6%) and 10 women (33.4%) with a mean age of 35 years (20-65 years). The clinical features were dominated by abdominolumbar pain (22 cases), haematuria (12 cases) and pyuria (2 cases). Horseshoe kidney was associated with renal stones (20 cases), ureteropelvic junction syndrome (8 cases), upper urinary tract tumour (1 case). Treatment was surgical depending on the aetiology. The objective of this study was to analyse the epidemiological and diagnostic features of this disease, as well as the therapeutic features specific to each uropathy associated with horseshoe kidney.

Clinical analgesic nephropathy.

Analgesic nephropathy is recognized worldwide, but the differences in incidence in various countries, or regions, remain unexplained. Analgesic compounds may cause both functional and structural renal damage. This damage may be related to depletion of glutathione and renal vasoconstriction (probably mediated through prostaglandin depletion) and to the fact that the concentrations of glutathione and prostaglandins and their metabolites in the kidneys are manyfold their concentrations in plasma. Most patients with analgesic nephropathy are middle-aged women with histories of peptic ulcer, anemia, psychiatric disorders, headaches, and arthralgias. Investigations often show pyuria, some bacteriuria, and impaired concentrating ability, as well as other abnormalities of tubular function; caliceal abnormalities on intravenous pyelography are also frequent. It is important to discover these patients; evidence exists that with cessation of drug ingestion, renal function may stabilize and, in some cases, may improve.

The differentiation of classic Kawasaki disease, atypical Kawasaki disease, and acute adenoviral infection: use of clinical features and a rapid direct fluorescent antigen test.

OBJECTIVE: To compare the clinical and laboratory features of children with Kawasaki disease with those with acute adenoviral infection, which may mimic Kawasaki disease. DESIGN: We retrospectively compared the medical records of children with Kawasaki disease and atypical Kawasaki disease with those of children with acute adenoviral infection. All children included were initially evaluated because their primary care physicians were concerned that they might have Kawasaki disease. The utility of a rapid direct fluorescent antigen test for adenovirus was evaluated. Thirty-six children with Kawasaki disease (23 with classic and 13 with atypical presentations) and 7 patients with acute adenoviral infection were studied. SETTING: A tertiary care pediatric hospital. RESULTS: Children with Kawasaki disease were more likely to have conjunctivitis (36 of 36 vs 4 of 7), strawberry) tongues (23 of 36 vs 1 of 7), perineal peeling (19 of 36 vs 0 of 7), and distal extremity changes (22 of 36 vs 0 of 7) than those with acute adenoviral infection. Children with acute adenoviral infection were more likely to have purulent conjunctivitis (3 of 7 vs 1 of 36) and exudative pharyngitis (3 of 7 vs 1 of 35). In addition to pyuria (13 of 26 vs 0 of 6), patients with Kawasaki disease had higher mean white blood cell counts (15.3 +/- 3.5 vs 11.5 +/- 6.0 x 10(9)/L), erythrocyte sedimentation rates (56 vs 42 mm/h), platelet counts (426 vs 259 x 10(9)/L), and levels of alanine aminotransferase (101 vs 18 U/L) than those with acute adenoviral infection. Children with Kawasaki disease had lower mean albumin levels (32 vs 36 g/L). A rapid antigen test for adenovirus had a specificity and sensitivity of 100% compared with viral culture. CONCLUSIONS: Kawasaki disease and acute adenoviral infection can present with many of the same clinical characteristics. A rapid direct fluorescent antigen assay for adenovirus may be a helpful adjunctive test for distinguishing acute adenoviral infection from Kawasaki disease.

Reliability of the urinalysis for predicting urinary tract infections in young febrile children.

BACKGROUND: Urinary tract infections (UTIs) are a common source of bacterial infection among young febrile children. Clinical variables affecting the sensitivity of the urinalysis (UA) as a screen for UTI have not been previously investigated. The limited sensitivity of the UA for detecting a UTI requires that a urine culture be obtained in some children regardless of the UA result; however, a proper urine culture requires an invasive procedure, so the criteria for its use should be optimized. OBJECTIVES: To determine how the sensitivity of the standard UA as a screening test for UTI varies with age, and to determine the clinical situation that necessitates the collection of a urine culture regardless of the UA result. METHODS: Retrospective medical record review of patients younger than 2 years with fever (>/=38 degrees C) seen in the emergency department during a period of 65 months. All urine cultures were reviewed for the collection method, isolates, and colony counts. A UA result was considered positive if the presence of 1 of the following was detected: leukocyte esterase, nitrite, or pyuria (>/=5 white blood cells per high power field). Patients who had a paired UA and urine culture were used to calculate the sensitivity, specificity, and likelihood ratios of the UA. The prevalence of UTIs was also subcategorized by age, race, sex, and fever. RESULTS: Medical records of 37 450 febrile children younger than 2 years were reviewed. Forty-four percent were girls. Median age and temperature were 10.6 months and 38.8 degrees C. A total of 11 089 patients (30%) had urine cultures obtained. The sensitivity of the UA was 82% (95% confidence interval [CI], 79%-84%) and did not vary by age subgroups. The specificity of UA was 92% (95% CI, 91%-92%). The likelihood ratios for a positive UA and negative UA were 10.6 (95% CI, 10.0-11.2) and 0.19 (95% CI, 0.18-0.20), respectively. Prevalence of UTI was 2.1% overall (2.9% for girls and 1.5% for boys, respectively). Among girls, the prevalence of UTI was 5.0% in white patients, 2.1% in Hispanic patients, and 1.0% in black patients. Among boys, the prevalence was 2.2% in Hispanic patients, 1.4% in white patients, and 0.8% in black patients. Higher prevalence was also seen among patients with a temperature at or above 39 degrees C compared with those whose temperature was between 38.0 degrees C and 38.9 degrees C. The greatest prevalence of UTI (13%) was found among white girls younger than 6 months with a temperature at or greater than 39 degrees C. The posttest probability of a UTI in the presence of a negative UA can be calculated using the negative likelihood ratio and the patient-specific prevalence of UTI. When the prevalence of UTI is 2%, 1 UA among 250 will produce a false-negative test result. CONCLUSIONS: The sensitivity of the standard UA is 82% (95% CI, 79%-84%) and does not vary with age in febrile children younger than 2 years. The prevalence of UTI varies by age, race, sex, and temperature. A negative likelihood ratio and estimates of prevalence can be used to calculate the risk of missing a UTI due to a false-negative UA result.

Mucocutaneous lymph node syndrome in the United States.

Sixteen patients with an unusual and distinct symptom complex were encountered during a four-year period. Principal features of this syndrome are (1) fever lasting more than seven days; (2) conjunctival injection; (3) changes in the mouth consisting of erythema of the oropharynx, "strawberry tongue", and erythema of the lips; (4) indurative edema of hands and feet with palm and sole erythema followed by desquamation of the fingertips; and (5) an erythematous rash. Associated features were lymphadenopathy, pyuria, aseptic meningitis, diarrhea, arthritis, and arthralgia. Although usually a self-limited illness, one patient died with massive coronary artery thrombosis on the 19th day of illness. This syndrome appears to be clinically and pathologically similar to mucocutaneous lymph node syndrome, an illness prevalent in Japan but previously unrecognized by American clinicians. Pathologic features suggest a relationship to infantile periarteritis nodosa.

Bacterial and viral pathogens causing fever in infants less than 3 months old.

We studied 182 sick, febrile (temperature greater than 38 degrees C) infants less than 3 months of age, who presented at our Tripler Army Medical Center, Honolulu, during a one-year period, to determine the relative causes of fever in this age group. Blood, cerebrospinal fluid, urine, nasopharyngeal secretions, and stool specimens were cultured for bacterial and viral pathogens. Paired acute and convalescent sera were collected to serologically confirm infection in infants from whom viral isolations were obtained only from the nasopharynx or stool. A viral pathogen was isolated in 75 infants (41%) and a bacterial pathogen was isolated in 27 infants (15%). Nonpolio enteroviruses were the most common pathogens demonstrated. They were isolated from 64 infants (35%), and 40 (62%) of these infants had aseptic meningitis, the most frequently made diagnosis. Urinary tract infection was the most common bacterial infection observed. It occurred in 20 infants (11%) and was most often seen without associated pyuria in uncircumcised male infants. Salmonellosis, the second most common bacterial infection, was observed in six infants (3%), and two of these did not have diarrhea or other gastrointestinal tract symptoms. No infant had septicemia and only one infant had bacterial (group B streptococcal) meningitis.

Use of ultrasonography in the detection of ureteric reflux in children suspected of having urinary infection.

The present study investigated whether ultrasonography was effective in detecting ureteric reflux in children suspected of having urinary infection. Seventeen children with febrile episodes and pyuria were enrolled. The ultrasound examination revealed ballooning of the renal pelvis during bladder contraction in 4 children, dilatation of the distal ureters in 6, and small kidney in 2. Cystography was performed on the 6 children with these ultrasound abnormalities and 1 child with two episodes of suspected urinary infection. Four children showed reflux. All of the 4 children had been found to have renal pelvic ballooning on ultrasound. None of the 10 children who did not undergo cystography had recurrence of urinary infection or significant bacteriuria during a median follow-up period of 12 months. Thus, scanning during bladder contraction was effective in detecting significant ureteric reflux.

Intestinovesical fistula in a patient with chronic lymphocytic leukemia: case report and literature review.

A case of intestinovesical fistula secondary to leukemic infiltration is described. The patient was known to have chronic lymphocytic leukemia and had been receiving chemotherapy fo ten months. She presented complaining of nausea, vomiting and vague abdominal pain. She initially denied genitourinary tract symptoms, although admitting urinalysis revealed pyuria, hematuria and bacteriuria. Urine cultures repeatedly grew E. coli despite broad spectrum antibiotic therapy. She eventually developed fecalant material in her urine and pneumaturia. Cystoscopy revealed a fistulous tract. At surgery an ileovesical fistula was found and histopathology showed lymphocytic leukemic infiltration. Intestinovesical fistulas are uncommon. Congenital, traumatic, inflammatory and solid neoplastic etiologies are well established in the literature. No previous cases have been attributed to hematologic malignancies. Since higher remission rates and longer periods of remission are being achieved with chemotherapy, and since fistula symptomatology may present quite subtly, awareness of this association may expedite diagnosis.
