Composition and spatial distribution of elements and isotopes of a giant human bladder stone and environmental implications.

Sci Total Environ 2019 Feb 8;650(Pt 1):835-846. Epub 2018 Sep 8.

School of Earth and Space Sciences, University of Science and Technology of China, Hefei, Anhui 230026, China; School of Life Sciences, University of Science and Technology of China, Hefei, Anhui 230026, China. Electronic address:

The composition and spatial distribution of minerals, trace elements, as well as carbon and nitrogen isotopes from the outer crust to inner nucleus of a 20-year old giant human bladder stone comprising thirteen layers were intensively investigated. Calcium oxalate monohydrate (COM) was found to concentrate in the inner and middle layers, struvite was concentrated in middle and outer layers, and fluorapatite occurred in almost all layers. The spatial distribution of minerals has the potential to provide preliminary knowledge regarding the long-term urine composition, or even the physiological condition of the patient. Read More

The diagnostic yield of computed tomography in the management of acute flank pain and the emergency intervention rate for a proven acute ureteric stone.

Ann R Coll Surg Engl 2018 Oct 5:1-8. Epub 2018 Oct 5.

West Suffolk NHS Foundation Trust , UK.

Introduction: The diagnostic and management pathways for patients presenting with acute flank pain are complex. Although computed tomography (CT) of the kidneys, ureters and bladder (KUB) is the gold standard investigation for urolithiasis, the multitude of differential diagnoses must also be considered in the context of long-term risk from ionising radiation. This study investigated the integrated role and diagnostic yield of non-contrast CT in cases of acute flank pain. Read More

4 Department of Surgery, Faculty of Veterinary Medicine and Animal Science, University of São Paulo, Brazil.

Objective The aim was to perform a case-control medical evaluation of cats from multi-cat households presenting with inappropriate latrining and spraying behavior. Methods Owners of 18 'spraying' and 23 'latrining' cats with normal control subjects available from the same households were recruited for a case-control study. Otherwise overtly healthy dyads (each dyad consisting of a case cat and a control cat) were brought together to the veterinary hospital of the University of São Paulo for a medical work-up (ie, physical examination, complete blood count, biochemical profile, urinalysis and urine culture, abdominal ultrasound of the urinary system and in females, where possible, cystoscopy).

Evaluation of an early twentieth century Afghan herbalist's preparations.

Forensic Sci Med Pathol 2018 Sep 27. Epub 2018 Sep 27.

School of Medicine, The University of Adelaide, Level 5 Helen Mayo South Building, Frome Road, Adelaide, South Australia, 5005, Australia.

Mahomet Allum was a flamboyant philanthropist and herbalist who worked in South Australia in the early part of last century, whose herbal therapies generated some controversy at the time. Two of his preparations have survived to the present day, a general tonic and a treatment for liver and kidney dysfunction. Given the frequent use of pharmaceutical drugs in "tonics" at the time, toxicological analysis was undertaken at Forensic Science SA, Adelaide with liquid chromatography/quadrupole-time-of-flight mass-spectrometer (LC-QTOF MS), liquid-chromatography/ diode array detector (LC/UV) and gas chromatography/ nitrogen phosphorous- detector/mass-spectrometer (GC-NPD/MS), to look for common drugs.

Guide sheath-assisted ureteroscope lithotripsy for upper ureteral calculi: An observational study on 81 cases.

Exp Ther Med 2018 Oct 20;16(4):3459-3463. Epub 2018 Aug 20.

Department of Urology, Ningbo First Hospital, Ningbo, Zhejiang 315000, P.R. China.

The present study assessed the clinical efficacy of guide sheath-assisted ureteroscope lithotripsy in the treatment of upper ureteral calculi. A total of 81 patients with upper ureteral calculi underwent ureteroscope lithotripsy assisted by a guide sheath between January 2012 and June 2014; of these, 63 patients were successfully treated with simple rigid ureteroscope lithotripsy assisted by a ureteral access sheath, and 18 patients were successfully treated with rigid and flexible ureteroscope lithotripsy assisted by a guide sheath. At 1 day after the surgery, ultrasound examination of kidneys, ureters and bladder, and urinary system computed tomography were used to re-check for residual stones, and 69 patients had stones with a diameter of <2 mm in the renal pelvis, while 12 had stones of 2-4 mm in diameter.

BMJ Case Rep 2018 Sep 12;2018. Epub 2018 Sep 12.

Department of Obstetrics and Gynecology, Texas Tech University Health Sciences Center, Lubbock, Texas, USA.

Over 200 000 surgeries for vaginal prolapse are done annually, and these are rarely urgent. However, when the rare event of bladder stones causes incarcerated procidentia, surgical intervention should not be delayed, due to unrelenting pain and end-organs effects. We present such a case below. Read More

Comparative Analysis of Laparoscopic Cholecystectomy Performed in the Elderly and Younger Patients: Should We Abstain from Laparoscopic Cholecystectomy in the Elderly?

Cureus 2018 Jun 27;10(6):e2888. Epub 2018 Jun 27.

General Surgery, Harran, Sanlıurfa, TUR.

Background: The elderly population is gradually increasing due to an increase in the quality of life and therefore the frequency of gallbladder stones in the population is also increasing. However, a considerable number of physicians tend to postpone or solve the problem with medical treatment instead of performing surgery in the elderly patients. In this study, we aim to compare the outcomes of laparoscopic cholecystectomy (LC) in the elderly and younger patients. Read More
