Accuracy of different diagnostic techniques for Schistosoma haematobium to estimate treatment needs in Zimbabwe: Application of a hierarchical Bayesian egg count model. PLoS Negl Trop Dis 2020; 14:e0008451. [PMID: 32817650 PMCID: PMC7462259 DOI: 10.1371/journal.pntd.0008451] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/14/2020] [Revised: 09/01/2020] [Accepted: 06/04/2020] [Indexed: 11/19/2022] Open
Abstract
BACKGROUND Treatment needs for Schistosoma haematobium are commonly evaluated using urine filtration with detection of parasite eggs under a microscope. A common symptom of S. haematobium is hematuria, the passing of blood in urine. Hence, the use of hematuria-based diagnostic techniques as a proxy for the assessment of treatment needs has been considered. This study evaluates data from a national survey in Zimbabwe, where three hematuria-based diagnostic techniques, that is microhematuria, macrohematuria, and an anamnestic questionnaire pertaining to self-reported blood in urine, have been included in addition to urine filtration in 280 schools across 70 districts. METHODOLOGY We developed an egg count model, which evaluates the infection intensity-dependent sensitivity and the specificity of each diagnostic technique without relying on a 'gold' standard. Subsequently, we determined prevalence thresholds for each diagnostic technique, equivalent to a 10% urine filtration-based prevalence and compared classification of districts according to treatment strategy based on the different diagnostic methods. PRINCIPAL FINDINGS A 10% urine filtration prevalence threshold corresponded to a 17.9% and 13.3% prevalence based on questionnaire and microhematuria, respectively. Both the questionnaire and the microhematuria showed a sensitivity and specificity of more than 85% for estimating treatment needs at the above thresholds. For diagnosis at individual level, the questionnaire showed the highest sensitivity (70.0%) followed by urine filtration (53.8%) and microhematuria (52.2%). CONCLUSIONS/SIGNIFICANCE The high sensitivity and specificity of a simple questionnaire to estimate treatment needs of S. haematobium suggests that it can be used as a rapid, low-cost method to estimate district prevalence. Our modeling approach can be expanded to include setting-dependent specificity of the technique and should be assessed in relation to other diagnostic methods due to potential cross-reaction with other diseases.

Abstract
A 23-year-old man presented to us with multiple episodes of visible haematuria associated with dysuria, but no other symptoms suggestive of infection. His physical examination was completely unremarkable. On detailed evaluation of history, it was noted that he was treated for urinary schistosomiasis as a child in Sudan. A diagnostic flexible cystoscopy, with both white light and narrow band imaging (NBI), was done among other tests as a further diagnostic tool to investigate possible causes. This revealed the characteristic features of bladder schistosomiasis. Urine microscopy for S chistosoma haematobium eggs was negative, and this could have caused the diagnosis to be missed. He was treated with praziquantel for chronic bladder schistosomiasis. This is the first time that the use of NBI as an adjunct to white light imaging in the diagnosis of bladder schistosomiasis has been reported.

Abstract
A case of acute kidney injury due to reflex anuria that was caused by retrograde pyelography and required temporary hemodialysis is reported. An 83-year-old Japanese woman presented with anuria 2 days after undergoing bilateral retrograde pyelography for the investigation of gross hematuria. Retrograde pyelography showed no apparent abnormality, such as malignancy or urolithiasis, but pyelorenal extravasation of contrast medium was remarkable. Her anuria improved promptly after hemodialysis, allowing her treatment to conclude with only one hemodialysis session, and a normal renal function was restored with no sequelae. The details of this case and a review of the relevant literature are presented.

Abstract
A 71-year-old woman with abnormal pulmonary shadows and multiple enlarged thoracic lymph nodes was diagnosed with stage IIB lung adenocarcinoma, pulmonary sarcoidosis, and sarcoidosis-associated lymphadenopathy after biopsies from multiple organ sites. She also had rapidly progressive renal dysfunction, microhematuria, and high myeloperoxidase anti-neutrophil cytoplasmic antibody (MPO-ANCA) concentrations. A renal biopsy revealed granulomatous tubulointerstitial nephritis and necrotizing glomerulonephritis with crescent formation. She was diagnosed with nephritis caused by both sarcoidosis and ANCA-associated vasculitis. Oral prednisolone was administered to treat her nephritis, resulting in improvement in both her renal dysfunction and her sarcoidosis-associated lymphadenopathy.

Abstract
OBJECTIVE To investigate the clinical characteristics of patients with acute renal infarction (ARI) and explore the possible clinical and/or laboratory parameters relative to hematuria. METHODS Medical records of 52 patients hospitalized with radiologic proven ARI were retrospectively reviewed. Clinical characteristics, including demographic data, risk factors for thromboembolism, initial clinical presentations, laboratory data, diagnosis, treatment programs and outcomes were evaluated and compared between hematuria(+) and hematuria(-) patients. RESULTS The mean age of the patients (34 men and 18 women) was (56.3±14.8) years. The left, right, and bilateral kidneys were involved in 44.2%, 34.6% and 21.2% of the patients, respectively. Focal, multiple and massive infarctions were involved in 36.5%, 50.0% and 13.5% of the patients. The prevalence of concurrent thromboembolic events was 38.5%. Atrial fibrillation was complicated in 44.2% of the patients. ARI often presented with nonspecific symptoms, including abdominal/flank pain (71.2%), nausea (55.8%), lumbar pain (53.9%), vomiting (48.1%), fever (48.1%), and diarrhea (21.2%). Percussion tenderness over kidney region was the most common sign (40.4%). The levels of serum lactate dehydrogenase, white blood cell count and C-reactive protein were elevated in 86.5%, 67.3%, and 54.5% of cases, respectively. Hematuria was detected in only 38.5% of the cases on admission. Elevation of serum D-dimer was only noted in 56.5% of the patients. The median duration from hospital presentation to diagnosis was 41.5 h (range: 2-552 h). Contrast-enhanced computed tomography was diagnostic in 47 (90.4%) cases. Angiography was positive in the other 5 (9.6%) cases. Anticoagulation was the most common therapy. During a mean follow-up of (39.4±35.8) months, renal functions of most patients were stable. Four patients needed permanent dialysis and one patient died of heart failure. There was no statistical significance between hematuria (+) group and hematuria (-) group for all the parameters except the level of serum lactate dehydrogenase, which was higher in hematuria(+) group [773.5 IU/L (range: 153.0-3 159.0 IU/L) vs. 488.0 IU/L (range: 137.0-3 370.0 IU/L), P=0.041]. CONCLUSION Thromboembolism due to heart disease is the main etiology of ARI. Early contrastenhanced computed tomography scan should be considered for high-risk patients with persisting abdominal or lumbar pain and elevated serum level of lactate dehydrogenase. Hematuria is not a sensitive clue for diagnosis and is not relative to prognosis. Whether it is present may be determined by the severity of infarction.

Abstract
Early diagnosis of bladder cancer is crucial for improvement of cancer specific survival and recurrence rate. We analyzed the possible role of fluorescence urine analysis in bladder cancer diagnosis. The cohort consisted of 20 healthy controls, 40 patients with hematuria and 75 patients with hematuria and histologically proven bladder tumor. Synchronous fluores- cence spectra with a 70 nm wavelength difference were recorded for (1:1-1:128) urine dilutions. Concentration matrices of synchronous spectra (CMSS) were used to classify samples into tested groups. CMSS analysis allowed us to distinguish patients with tumor from patients with hematuria with a sensitivity 55% and specificity 74.7%. This is comparable to the sensitivity and specificity of other non-invasive tests like BTA stat and nmP-22 (Bladder check®). Lower fluorescence inten- sity of Imax 280 nm and ratio of 280 nm to 450 nm was found to be associated with the presence of tumor. We have found an association of decreased fluorescence with the stage of the disease. Our data suggest that CMSS urine analysis has a potential role in the non-invasive diagnostic tests for bladder cancer, but it cannot replace the current diagnostic algorithm yet.

Abstract
Objectives: To evaluate the general knowledge among primary health care (PHC) physicians regarding the management of common urological problems in Saudi Arabia. Methods: This is an observational prospective study, where a self-administered questionnaire was distributed to practicing PHC physicians in the western region of Saudi Arabia on January 2017. The questionnaire consisted of 21-item questions, inquiring about demographics and general urological knowledge and skills. The management of common urological problems was assessed by case scenarios for specific urological condition, including urethral catheterization, definition and evaluation of hematuria, recognition of age-specific increase in prostatic specific antigen (PSA), and management of lower urinary tract symptoms. Results: A total of 148 questionnaires were distributed, with a response rate of 75.7%, where 112 respondents completed the questionnaires, including 54.3% residents, 39% general practitioners, and 5.4% specialists. Fifty-seven percent of respondents were males and 68% were Saudi practitioners. A higher number of respondents expressed that they were able to catheterize a male than female patient (56.5% versus 34.3%). Only 6.4% of respondents defined microscopic hematuria accurately. Knowledge about hematuria, serum prostate specific antigen and overactive bladder was low in all groups. Apart from hematuria, seeking urological consultations was less than 35% for all other disease entities. Conclusion: Urological knowledge among PHC physicians seems to be insufficient. Significant percentages of the participants were unable to catheterize a female patient, did not know the definition of hematuria; and whether to ask for urological consultations in cases of hematuria, increased PSA, and overactive bladder.

Abstract
Trichosporon urinary tract infection (UTI) is an unusual emerging infection, caused mostly by Trichosporon asahii, described especially in hospitalized patients. To date the interpretation and management of Trichosporon positive urinary culture remains a diagnostic and therapeutic dilemma for which there are no precise indications, and the challenge can be even more complicated in comorbid frail elderly patients. Triazoles are known to be the most effective antifungal drugs but can raise concerns about pharmacological interaction. We report a case of Trichosporon asahii nosocomial UTI in an elderly patient.

Abstract
INTRODUCTION Although general guidelines exist directing the management of new/novel oral anticoagulants (NOACs) in the perioperative period for open/endoscopic procedures, no consensus exists for those patients being considered for shockwave lithotripsy (SWL). To gauge current practice, we administered a survey to the international endourologic community. METHODS A web-based survey was sent to current Endourological Society members. Respondents were asked whether they would consider SWL in patients receiving NOACs, and if they used SWL how these agents were managed perioperatively. Respondents were also asked which physicians in the patients' circle of care managed the discontinuation and reinstitution of the drugs. RESULTS There were 165 respondents from 27 countries. Approximately 92.7% of urologists had access to SWL but only 53.4% indicated they would offer SWL to patients receiving NOACs. Among these urologists, 63.3% relied on internal medicine/hematology/cardiology colleagues to counsel patients on the discontinuation of NOACs pretreatment, whereas the majority (64%) handled the resumption guidance themselves. There was wide variability in the management of NOACs before lithotripsy, with discontinuation varying from 2 to 7 days. Resumption was more consistent, ranging from 1 to 2 days or when hematuria resolved. None of the respondents reported knowledge of adverse effects such as perinephric hematomas or cardiovascular morbidity. CONCLUSIONS A large percentage of globally surveyed endourologists do not offer SWL to patients who are taking NOACs. Among those that do offer SWL, there seems to be a absence of consensus on optimal duration of discontinuation, suggesting a need to establish evidence-based guidance to optimize patient outcomes.

Abstract
A diagnostic procedure for acute kidney injury. The definition of acute kidney injury (AKI) is universal since 2011. It is simple, based on the increase in serum creatinine on a short time period. AKI may be life-threatening, which is why the priority is to rule out hyperkalemia, pulmonary edema, or severe acidosis. Then, a panel of clinical, biological and radiological analyses is required to establish the mechanism of AKI and treat it appropriately. Basically, a three steps process is suggested: an obstruction of the urinary cavities is looked for; circumstances of renal hypoperfusion are considered, and urinary electrolytes measured; by elimination, a diagnosis of parenchymal AKI is eventually made. In that case AKI is in most cases due to an acute tubular necrosis, which implies to collect positive and negative signs: a recent history of hypotension, intake of toxic drugs, etc.; proteinuria should be low, i.e. less than 1 g/L, and urinary cells in normal count. In the presence of extra-renal symptoms, and of urinary abnormalities such as abundant proteinuria and hematuria or leucocyturia, a specialized care is urgently needed and a renal biopsy often indicated.

Abstract
Acute renal failure of glomerular origin. Glomerulopathies account for about 10% of acute kidney injury (AKI) in adults. They often require urgent care. The clinico-biological presentations are acute nephritic syndrome (GNA) and rapidly progressive glomerulonephritis. GNA combines an organic AKI with signs of sodium retention. The most commonly found germs are streptococci, staphylococci and Escherichia coli. Rapidly progressive glomerulonephritis is characterized by a renal failure that settles in a few weeks, with marked hematuria. Blood tests depend of the context but include complement study and ANCA. Histologically, extracapillary lesions are present with various immunoglobulin deposits.

Abstract
Acute renal failure by acute tubular necrosis. In adults, acute tubular necrosis is the leading cause of acute kidney injury (AKI). Secondary to ischemia and/or tubular toxicity, the commonly found histological lesions are desquamation of tubular epithelial cells and hyaline intra-tubular deposits. AKI is frequently observed with a non-altered urine output and associated with a proteinuria less than 1.5 g/24h without albuminuria, hematuria or leucocyturia. The association of an evocative clinical context and a spontaneous improvement of the AKI confirmed the diagnosis of acute tubular necrosis. The prognosis mimics that of the AKI and is often severe. Despite a functional recovery, the cellular repair is abnormal. This "maladaptive repair" phenomenon leads to accelerated renal aging and increase the susceptibility to nephrotoxicity. Consequently, the risk of chronic kidney disease becomes more important. Actually, no specific treatment of the acute tubular necrosis exists, however, because the "maladaptive repair" phenomenon, for patients exposed to more severe acute tubular necrosis, including those that have functionally recovered, a regular monitoring of renal function associated with simple nephroprotection's measures are recommended over the course of AKI.

Abstract
OBJECTIVES Non-contrast computed tomography (NCCT) is not always performed clinically if the diagnosis of ureteral calculi has been confirmed using other radiographic imaging modalities. The aim of this study was to identify predictors of successful extracorporeal shockwave lithotripsy (ESWL) without assistance of NCCT. METHODS We retrospectively reviewed the medical records of patients with symptomatic solitary ureteral stones who underwent ESWL between November 2015 and January 2016. Abdominal plain radiography or intravenous urography were performed before ESWL for localization. The exclusion criteria were repeated sessions of ESWL for the target stone and congenital genitourinary tract anomalies. The demographic characteristics, clinical history, medical charges, or imaging features of the stones were recorded. Successful treatment was defined as no fragments detected on radiography or ultrasonography in 4 weeks. For radiolucent calculi, successful treatment was regarded as cases without hydronephrosis, symptoms, or hematuria. Patients experiencing intractable pain and undergoing subsequent auxiliary surgeries were regarded as having ESWL treatment failure. RESULTS Age (odds ratio [OR], 1.042; 95% confidence interval [CI], 1.007-1.078), history of ipsilateral renal or ureteral calculi episodes (OR, 2.669; 95% CI, 1.281-5.687), stone burden (OR, 3.499; 95% CI, 1.284-9.530), and radiopaque stone (OR, 2.351; 95% CI, 1.049-5.267) were significant predictors of ESWL failure in all patients. CONCLUSIONS For treating symptomatic ureteral stones, those with smaller size, radiolucency, and without a history of ipsilateral renal or ureteral calculi could be considered for first-line therapy with ESWL.

Abstract
OBJECTIVE To compare the efficacy and safety of staged retrograde flexible ureteroscopic lithotripsy (FURS) and miniaturized percutaneous nephrolithotomy (m-PCNL) for treatment of renal stones of 2-4 cm in diameter. METHODS This randomized controlled trial was conducted in 70 patients with renal stones of 2-4 cm in diameter admitted in our hospital between January 2013 and December 2015. The patients were randomized to receive staged FURS (35 cases) or m-PCNL (35 cases), and the total treatment time, total hospital stay after procedure, total medical cost, treatment success, decrease in hemoglobin level and complications were compared between the two groups. RESULTS The treatment success rate was 100% in both groups, but the complete stone-free rate was significantly lowered in FURS group than m-PCNL group (65.71% vs 94.29%, P<0.01). The average decrease in hemoglobin level was 3.37∓1.56 g/L in FURS group and 11.93∓2.24 g/L in m-PCNL group (P<0.01). The overall complication rates in the two groups were 6.25% and 9.37%, respectively (P>0.05). Minor complications (grade I by Clavien-Dindo classification) occurred in one case in FURS group (fever) and two cases in m-PCNL group (self-limiting hematuria); major complications (grade II) occurred in one case in FURS group (steinstrase) and one case in m-PCNL group (blood transfusion). In staged FURS and m-PCNL groups, the mean total treatment time was 4.06∓1.11 vs 1.26∓0.47 weeks (P<0.01), the mean hospital stay after procedure was 3.66∓1.29 vs 5.13∓0.43 days (P<0.01), and the mean total medical cost was 54 291.00 RMB ∓6149.00 vs 23 482.00 RMB ∓2317.00 (P<0.01), respectively. CONCLUSION FURS is safe and effective for treatment of renal stones of 2-4 cm in diameter, and a staged procedure is necessary to achieve a stone-free status for large calculi. Both sophisticated equipment and rich surgical experience are essential to ensure treatment success.
