The relationship between the coral genotype and the environment is an important area of research in degraded coral reef ecosystems. We used a reciprocal outplanting experiment with 930 corals representing ten genotypes on each of eight reefs to investigate the influence of genotype and the environment on growth and survivorship in the threatened Caribbean staghorn coral, Acropora cervicornis. Coral genotype and site were strong drivers of coral growth and individual genotypes exhibited flexible, non-conserved reaction norms, complemented by ten-fold differences in growth between specific G-E combinations...

Urolithiasis is a significant worldwide source of morbidity, constituting a common urological disease that affects between 10 and 15% of the world population. Recent technological and surgical advances have replaced the need for open surgery with less invasive procedures. The factors which determine the indications for percutaneous nephrolithotomy include stone factors (stone size, stone composition, and stone location), patient factors (habitus and renal anomalies), and failure of other treatment modalities (ESWL and flexible ureteroscopy)...

Percutaneous nephrolithotomy is a recognized standard for minimally invasive treatment of large kidney stones. Percutaneous interventions for complete staghorn stones are associated with a higher risk of complications that precludes abandoning the traditional open operations, one of which is an anatrophic nephrolithotomy. This paper presents the first personal experience in laparoscopic transmesenteric anatrophic nephrolithotomy. The intervention was conducted in 3 patients (2 males and 1 female) aged 43 to 58 years, having a primary symptomatic complete left kidney staghorn stones sized from 7...

INTRODUCTION AND OBJECTIVE: Percutaneous nephrolithotomy (PCNL) is the gold standard treatment for kidney stones regardless of age. Elderly patients (EP)≥65years old, in growing numbers, have more comorbidities than the general population, may alter results of PCNL. The aim of this meta-analysis was to compare efficacy and complications of this procedure between EP and young patients (YP). METHODS: Original studies of prospective and historical cohorts, in English or French, presenting PCNL series published on PubMed until 2015 were identified using the keywords percutaneous nephrolithotomy, elderly patients, kidney stones and staghorn calculi...

The combined effects of the herbicide glyphosate and elevated temperature were studied on the tropical staghorn coral Acropora formosa, in Nha Trang bay, Vietnam. The corals were collected from two different reefs, one close to a polluted fish farm and one in a marine-protected area (MPA). In the laboratory, branches of the corals were exposed to the herbicide glyphosate at ambient (28 °C) and at 3 °C elevated water temperatures (31 °C). Effects of herbicide and elevated temperature were studied on coral bleaching using photography and digital image analysis (new colorimetric method developed here based on grayscale), chlorophyll a analysis, and symbiotic dinoflagellate (Symbiodinium, referred to as zooxanthellae) counts...

A 55-year-old male presented, in June 2013, with left flank pain. Investigations revealed a complete staghorn stone. He had undergone two sittings of extracorporeal shock wave lithotripsy (ESWL) in 2008 for left renal stone. One year subsequent to this, he was diagnosed with hypertension and diabetes. The management of complete staghorn stones in a single sitting is a difficult proposition. Percutaneous nephrolithotomy (PCNL) is the gold standard to manage such stones. The patient was subjected to PCNL, and complete clearance was achieved in one sitting...

A solitary fibrous tumor is a neoplasm generally arising from the mesothelial surfaces of the pleura and mesothelium. In this paper, we describe three cases of rare solitary fibrous tumors arising from the orbit and discuss the management of the tumors, including diagnosis and treatment. All three cases were treated by surgical resection and showed satisfactory aesthetic and functional results. For a definitive diagnosis, immunohistochemical staining for proteins such as vimentin, CD34 and bcl-2 and hematoxylin and eosin (H&E) staining for identifying the morphological characteristics of spindle cell tumors with a partially storiform pattern and staghorn vessels are indispensable...

Background - Stones in common bile duct are defined as 'large' if they are more than 15 mm in size. There are very few reports which describe a giant stone measuring 5 cm or more and exceptionally a staghorn calculus in the common bile duct. Purpose - The purpose is to report a new rare case of giant staghorn gallstone and discuss the diagnostic approach and therapeutic possibilities. Case report - We report a case of a giant staghorn common bile duct calculus in a 65-year-old patient. Its removal required 2 operations and an endoscopic retrograde cholangiopancreatography with endoscopic sphincterotomy...

By inflicting damage to prey tissues, consumer species may increase stress in prey hosts and reduce overall fitness (i.e., primary effects, such as growth or reproduction) or cause secondary effects by affecting prey interactions with other species such as microbes. However, little is known about how abiotic conditions affect the outcomes of these biotic interactions. In coral reef communities, both nutrient enrichment and predation have been linked to reduced fitness and disease facilitation in corals, yet no study to date has tested their combined effects on corals or their associated microbial communities (i...

BACKGROUND: Percutaneous nephrolithotomy (PCNL) is recommended for treating staghorn stones or stones measuring > 20 mm. Extracorporeal shockwave lithotripsy (ESWL) or flexible ureteroscopy (URS) may be used as a complement. However, PCNL can cause trauma to the kidney parenchyma, and patients may find a noninvasive procedure, such as ESWL, to be more attractive. OBJECTIVES: The aim of this study was to evaluate the clinical efficiency of MiniJFil® stenting associated with ESWL or second-line URS for the treatment of medium-to-large kidney stones...
