#1
Julian A Michely, Markus R Meyer, Hans H Maurer
Dried matrix spot (DMS) technique as alternative sampling strategy, especially dried urine spots (DUS), might be an alternative for drug screening. So far only particular drugs or drug classes were covered in DMS screenings. Therefore, workup of DUS for a broad comprehensive library-based LC-MS(n) screening was developed. It consisted of enzymatic on-spot deconjugation followed by liquid extraction and LC-MS(n) analysis. This workup was compared to established urine precipitation (UP) and validated according to international guidelines for qualitative approaches, using exemplary compounds of several drug classes (antidepressants, benzodiazepines, cardiovascular drugs, neuroleptics, opioids, stimulants, etc...

Methamphetamine is one of the most common abused drugs, so its various effects on different body organs should be familiar to all physicians. Regarding its gastrointestinal sequels, there are few reports of ischemic colitis induced by its vasoconstrictive effects. This is the first report of isolated small intestinal infarction resulting in death following methamphetamine toxicity. A 40-year-old woman with a past history of medical treatment for obesity referred to hospital with severe chest and back pain, perspiration, nausea, agitation, high blood pressure, bradycardia and subsequent lethargy and vasomotor instability...

BACKGROUND: If untreated, paediatric neurogenic bladder can cause renal failure and urinary incontinence. It is usually caused by neural tube defects such as myelomeningocele. Children with a neurogenic bladder should be monitored from birth and management should aim to preserve renal function and achieve social continence. This article outlines the management options appropriate for these children in resource-poor settings. ASSESSMENT: In most low- and middle-income countries, a general lack of awareness of the neurological effects on the urinary tract results in late presentation, usually with urological complications even when spina bifida is diagnosed early...

BACKGROUND: Preemptive screening of urine for patients admitted to an intensive care unit can result in misinterpretation of data and over- or under-treatment of urinary tract infection. METHODS: Data were studied from 169 consecutive patients admitted to the neurologic or burn intensive care unit at Shands Hospital at the University of Florida. All patients had a urinary catheter in place at the time of admission. Urinalysis and urine culture were sent for analysis...

OBJECTIVES: Urine microscopy is a common test performed in emergency departments (EDs). Urine specimens can easily become contaminated by different factors, including the collection method. The midstream clean-catch (MSCC) collection technique is commonly used to reduce urine contamination. The urine culture contamination rate from specimens collected in our ED is 30%. We developed an instructional application (app) to show ED patients how to provide a MSCC urine sample. We hypothesized that ED patients who viewed our instructional app would have significantly lower urine contamination rates compared to patients who did not...

Millions of people worldwide take tenofovir disoproxil fumarate (TDF) for the treatment of human immunodeficiency virus (HIV) and/or hepatitis B infection. Although generally safe and well tolerated, clinicians need to be aware that TDF can cause proximal renal tubular dysfunction and loss of bone mineral density, especially in patients with concomitant renal disease or other risk factors. We present the case of a patient with chronic HIV infection and urethral stricture who developed TDF-related proximal renal tubular dysfunction with hypophosphatemia and osteomalacia, presenting with bone pains, skeletal deformity, and disability...

INTRODUCTION: Urinary biomarkers of kidney injury are presumed to reflect renal tubular damage. However, their concentrations may be influenced by other factors, such as hematuria or pyuria. We sought to examine what non-injury related urinalysis factors are associated with urinary biomarker levels. METHODS: We examined 714 adults who underwent cardiac surgery in the TRIBE-AKI cohort that did not experience post-operative clinical AKI (patients with serum creatinine change of ≥ 20% were excluded)...

Urinary incontinence symptoms are highly prevalent among women, have a substantial effect on health-related quality of life and are associated with considerable personal and societal expenditure. Two main types are described: stress urinary incontinence, in which urine leaks in association with physical exertion, and urgency urinary incontinence, in which urine leaks in association with a sudden compelling desire to void. Women who experience both symptoms are considered as having mixed urinary incontinence...

INTRODUCTION: With advancements in endoscopic surgery, open surgical techniques for urinary system stones have paved the way for the application of less invasive treatment modalities in patients with pediatric kidney stone disease. These treatment options include extracorporeal shock wave lithotripsy (ESWL), percutaneous nephrolithotomy (PCNL), and retrograde intrarenal surgery (RIRS). OBJECTIVE: We aimed to compare the efficacy and safety of RIRS and micro-PCNL techniques in the surgical treatment of kidney stones in pediatric patients...

INTRODUCTION: The risk of post-procedural urinary tract infection (ppUTI) after retrograde urethrogram (RUG) has not been well quantified. Prophylactic antibiotics may reduce the risk, but must be weighed against the risks of antibiotic resistance. Prior research has shown that this risk is variable after voiding cystourethrogram (0-42% reported ppUTI rate) and appears to be low after urodynamics (0-4.8%) but this risk has not been well documented for patients undergoing RUG. OBJECTIVE: We aimed to (1) describe the rate of ppUTI after RUG, and (2) examine factors associated with use of antibiotics at the time of RUG...

The subchronic toxicity of jelly mushroom glycolipids from Dacryopinax spathularia (herein referred to as "AM-1") was studied in Crl:CD(SD) rats. The test item was administered via the drinking water at concentrations of 1.5, 5.0 or 15 mg/mL for 90 days with an additional 4-week recovery period. No test article-related deaths, clinical observations or neurological effects were noted. Decreased drinking water consumption for mid- and high-dose groups was attributable to the reduced palatability of drinking water containing higher test article concentrations...

INTRODUCTION: National data on iodine status in Israel is lacking. Reliance on iodine-depleted desalinated water, the absence of a salt iodization program and reports of increased use of thyroid medication in Israel suggested that the population's iodine intake is likely inadequate. AIMS: To determine iodine status of Israeli school age children (SAC) and pregnant women (PW) in a nationally-representative sample obtained by a novel approach of using pre-discard urinalysis samples collected from a centralized national laboratory...
