P W Franks, N Atabaki-Pasdar
Obesity is a risk factor for a plethora of severe morbidities and premature death. Most supporting evidence comes from observational studies that are prone to chance, bias and confounding. Even data on the protective effects of weight loss from randomized controlled trials will be susceptible to confounding and bias if treatment assignment cannot be masked, which is usually the case with lifestyle and surgical interventions. Thus, whilst obesity is widely considered the major modifiable risk factor for many chronic diseases, its causes and consequences are often difficult to determine...

PURPOSE: A CT of the kidneys, ureters, and bladder (CTKUB) is the investigation of choice in suspected renal colic. Plain kidney, ureter, and bladder radiographs (KUB) can be used to monitor the progress of a stone if radiographically visible on a baseline KUB. This study aims to determine if a low-dose CT Scout, thick-slab average intensity projection (AIP), or maximum intensity projection (MIP) images are suitable as substitutes for a baseline KUB. METHOD: A retrospective review of patients from a tertiary adult institute that had a positive CTKUB and a KUB within 4 h of the CT was performed...

Introduction Tobacco smoking is one of the most important risk factors for periodontitis as it alters the host response to plaque. Although the prevalence of tobacco smoking has declined in recent years, the use of electronic-cigarettes (vaping) has increased. The effect of vaping on the gingiva is unknown and an evidence-base needs to be established before providing dental advice about the use of these products.Objective To compare the gingival health of a group of established smokers before and after substituting vaping for smoking tobacco...

Renal stone disease is a frequent condition, causing a huge burden on health care systems globally. Calcium-based calculi account for around 75% of renal stone disease and the incidence of these calculi is increasing, suggesting environmental and dietary factors are acting upon a preexisting genetic background. The familial nature and significant heritability of stone disease is known, and recent genetic studies have successfully identified genes that may be involved in renal stone formation. The detection of monogenic causes of renal stone disease has been made more feasible by the use of high-throughput sequencing technologies and has also facilitated the discovery of novel monogenic causes of stone disease...

REVIEW
Sabri Soussi, Matthieu Legrand
Burn shock is characterized by profound hemodynamic alterations mainly associated with rapid loss of intravascular volume related to severe capillary leak. Thus, fluid resuscitation conventionally based on macrocirculatory targets is considered as a corner stone of initial management of patients with burns. Nonetheless, traditional markers such as blood pressure, urinary output, and cardiac output are helpful but do not sufficiently reflect the adequacy of perfusion and oxygenation at the microcirculatory level...

BACKGROUND: The most common biliary complications after orthotopic liver transplantation are bile leaks, anastomotic and intrahepatic strictures, stones, and ampullary dysfunction. These complications can occur in up to 10% to 30% of liver transplant recipients. Leaks occur early in the posttransplant period; the stricture formation typically graduates over time. METHODS: Ten patients underwent transplantation in our preliminary study: 5 were randomized to the group with stent placement and 5 to the control group...

Mainz pouch II is a reliable and viable technique of continent urinary diversion. Patients are at increased risk of long-term complications including urolithiasis of the upper urinary tract and reservoir. We report the case of a 67-year-old male with prior Mainz pouch II due to invasive bladder cancer treated for a large renal calculus. Percutaneous nephrolithotomy (PCNL) was successfully performed. Stone management in these type of patients is of increased interest due to existed "anatomical challenges" concerning the access and safety during the procedure...

Fish provide a valuable source of beneficial nutrients and are an excellent source of low fat protein. However, fish are also the primary source of methylmercury exposure in humans. Selenium often co-occurs with mercury and there is some evidence that selenium can protect against mercury toxicity yet States issue fish consumption advisories based solely on the risks that methylmercury pose to human health. Recently, it has been suggested the selenium: mercury molar ratio be considered in risk management. In order for agencies to utilize the ratio to set consumption guidelines, it is important to evaluate the variability in selenium and mercury in different fish species...

BACKGROUND: Laparoscopic hepatectomy remains one of the most difficult procedures for young surgeons to perform. We recently developed a new training method and standardization procedure for teaching young surgeons to perform laparoscopic left hepatectomy (Lap-LHx). The aim of this study was to assess the effectiveness of our method. METHODS: In 2004, we standardized a laparoscopic procedure for Lap-LHx, using a laparoscopy-assisted method as a stepping stone. The laparoscopic training method comprised the following three steps: (1) training in fundamental procedures using a dry box and checking by mentors; (2) detailed preoperative simulation using Vincent three-dimensional software for each patient; and (3) self-assessment including understanding of relevant anatomy and completion grade for each procedure using a check sheet and feedback by both mentors and a professor...

REVIEW
Allen L Rodgers
In this article, the term "physicochemical mechanism" is defined as a sequential series of steps culminating in the formation of a renal stone. Distinctions are drawn between physicochemical prerequisites for urinary supersaturation, crystallization, and stone formation. In particular, attention is focussed on the transition from crystal to stone. Emphasis is laid on crystal retention being the fundamental mechanism by which stones are formed, and mention is made of the different ways in which it can be achieved...
