REVIEW
Zeke P Oliver, Jack Perkins
Identifying sources of infection and establishing source control is an essential component of the workup and treatment of sepsis. Investigation with history, physical examination, laboratory tests, and imaging can in identifying sources of infection. All organ systems have the potential to develop sources of infection. However, there are inherent difficulties presented by some that require additional diligence, namely, urinalysis, chest radiographs, and intraabdominal infections. Interventions include administration of antibiotics and may require surgical or other specialist intervention...

BACKGROUND: The reports on disseminated candidiasis in dogs so far describe at least one predisposing factor. This case report, however, highlights candidiasis in a dog without any known predisposition. PATIENT: A 1.5-year-old intact female Hovawart dog was presented with subcutaneous nodules and polyuria/polydipsia. An excisional biopsy revealed a chronic pyogranulomatous and necrotizing inflammation with mycotic structures. The patient became febrile and lethargic, and developed lameness...

Early detection and appropriate management of chronic kidney disease can reduce the progression of kidney failure and cardiovascular disease. The urine albumin to creatinine ratio (UACR) test is a standard urine test for identifying individuals at high risk of developing progressive kidney disease. In this study, IDATPE, a novel fluorescent probe with aggregation-induced emission (AIE) features, is successfully developed for creatinine detection and quantitation. An excellent correlation between fluorescent light intensity and creatinine concentration is achieved...

BACKGROUND: Lower urinary tract symptoms are highly prevalent and a large proportion of these symptoms are known to be associated with a dysfunction of the afferent pathways. Diagnostic tools for an objective and reproducible assessment of afferent nerve function of the lower urinary tract are missing. Previous studies showed first feasibility results of sensory evoked potential recordings following electrical stimulation of the lower urinary tract in healthy subjects and patients. Nevertheless, a refinement of the methodology is necessary...

A 14-year-old girl was treated for 3 days with tosufloxacin (450 mg twice a day) for acute bronchitis and then developed acute kidney injury. Renal ultrasound showed enlarged kidneys without hydronephrosis. Urinalysis indicated drug crystal casts (2-3/HPF), consistent with drug-induced crystalline nephropathy. The patient recovered gradually with i.v. hydration and discontinuation of tosufloxacin, leading to the diagnosis of tosufloxacin crystalline nephropathy. Medical practitioners should be aware that crystalline nephropathy can occur in pediatric patients receiving tosufloxacin...

This paper introduces an integrated microfluidic chip as a promising tool to measure the concentration of bladder cancer cells (BCC) in urine samples. Silicon microchannels were used as trapping gates for both floated BCC and leukocytes which are found in the urine of patients. By the assistance of the gold electrodes patterned at the bottom of the micro gates, the capacitance of captured cancerous and blood cells were measured. Different membrane capacitance between BCC and leukocyte was the indicative signal for diagnosing the nature of captured cells in a urine like solution...

BACKGROUND It is important for an ophthalmologist and nephrologist to look for hidden causes of uveitis and nephritis, respectively. Delay in diagnosis leads to increased morbidity and failure to systemically manage the patient results in future recurrence of disease. It is likely that TINU remains underdiagnosed and could potentially account for some of the cases of idiopathic uveitis, especially when greater than 50% of uveitis cases have no identifiable cause. Fewer than 300 cases of tubulointerstitial nephritis and uveitis (TINU) syndrome have been reported...

BACKGROUND: Hypertension is as prevalent in many developing countries, as in the developed world and is the leading cause of cardiovascular morbidity and mortality in Africa. The control of hypertension in this resource limited setting is inadequate, a situation that translates into poorer outcomes in form of increasing incidences of stroke, heart failure, kidney failure and therefore early cardiovascular death. METHODS: This was a chart review of all the patients seen during the months of September 2012 to February 2013...

The workup and interpretation of urine cultures is not always clear-cut, especially for midstream samples contaminated with commensals. Standard urine culture (SUC) protocols are designed in favor of growth of uropathogens at the expense of commensals. In selected clinical situations, however, it is essential to trace fastidious or new uropathogens by expanding the urine culture conditions (EUC). The aim of our study was to map the microflora in midstream urine specimens from healthy controls by means of EUC, in view of the interpretation of bacterial culture results in symptomatic patients...

BACKGROUND: An alternative treatment for obstructive and refluxing obstructive megaureter with ureterovesical junction maintenance through laparoscopy is proposed. MATERIAL AND METHODS: The series consists of 8 cases, all of them studied because of prenatal hydronephrosis or febrile urinary tract infection. Seven were diagnosed with obstructive megaureter and one with obstructive refluxing megaureter. The procedure consisted in incising the stenotic portion of the ureter longitudinally and maintaining its posterior wall attached to the bladder, the anterior wall of the ureter was anastomosed transversally to the bladder mucosa in order to liberate the obstruction...

BACKGROUND: Urinalysis testing is frequently ordered in the emergency department (ED), but contamination of urine specimens limits the interpretation of results. The mid-stream, clean-catch (MSCC) procedure for urine specimen collection is recommended to decrease contamination rates, but without instructions this procedure has poor compliance. OBJECTIVE: To evaluate the effectiveness of written instructions alone, we analyzed the rate of specimen contamination, defined by presence of squamous epithelial cells (SECs) and culture results, in the ED after posting information on the MSCC procedure...

BACKGROUND: It is unclear when routine workup of postoperative pyrexia (POP) following total joint arthroplasty (TJA) should be performed. METHODS: A retrospective electronic database search was conducted on 25,558 consecutive patients undergoing primary or revision TJA between June 2001 and June 2013. We identified patient demographics, procedure type, characteristics of feverish patients, and febrile complications. The estimated costs for chest x-ray (CXR), urinalysis, urine culture, and blood culture were investigated...
