NEWS The Lumenis Pulse 100H,the next generation of theVersaPulse® Power- Suite™ 100Watt system,is a versatile and enhanced laser solution for the treatmentofawidearrayofclinicalurologicindicationsincludingbenignpro- static hyperplasia (BPH),stones,tumors or strictures,along with a range of other specialties such as general surgery, ENT, gynecology and pulmonary surgery. As a greatly effective laser system for stones and BPH, the Pulse 100H enables users to perform holmium laser enucleation of the prostate (HoLEP),the gold standard treatment for BPH,and stone dusting™. Thenewsystemfeaturesanimproveddesigntoenhancepatientsafetyand overall user experience.It offers a robust combination of laser parameters addressing more than 70 types of procedures, an innovative pulse reshape functionforimprovedsafety,dualpedalsforimprovedeaseofuse,ahands-free ready and standby mode for minimizing cost per procedure,and a high energy per pulse of up to 3.5J with a high repetition rate of up to 50Hz.In addition to the Pulse 100H,Lumenis will also be unveiling another key addition to the Lumenis Pulse laser family,the Pulse 50H laser system.Designed to efficiently address any type or size of stone in lithotripsy,the Pulse 50H system is a superior comprehensive solution that provides 0.2J of energy per pulse to minimize migration of even the smallest stone.Furthermore,the Pulse 50H can be later upgraded to the new Pulse 100H, allowing physicians to further leverage their investment as they grow their practice. “ThenewPulse50HsystemprovidesallfeaturestoperformmodernintracorporealHolmiumlaserlithotripsy including a wide range of energy levels and frequencies,”said Professor Rassweiler,MD,PhD,Klinikum SLK, Heilbronn,Germany. New pulse laser systems for A variety of indications 38 I laser4_2015 Two thousand years after Pompeii was buried under theashesofMt.Vesuvius,thearchaeologicalsitehas still kept most of its secrets. The plaster that was used in the early 19th century to fill the voids that the bodies had left in the hardened rock is so dense that today’s standard imaging technology cannot distin- guish between the thick outer cast and the skeletal pieces inside. Byusingaspecialmulti-layerCTscannerthatisable todojustthat,thespecialistshavebeenabletoshed newlightonthelifeanddeathoftheancientcivilisa- tion.Among other things, the scientific tests, which also included laser imaging and DNA sampling, re- vealed that the city’s inhabitants had nearly perfect teeth. “We discovered the absence of cavities in the teeth. This is very interesting and not that surprising, be- cause we all know about the healthy Mediterranean diet and this has really shown up in the early analy- ses,” said Massimo Osanna, superintendent at the archaeological site. According to the experts, the lack of sugar in the Pompeiandietandthehighlevelsoffluorineintheair and water near the volcano are all accountable for the perfect state of their teeth. In addition to an ex- cellent oral health, the researchers found that most of the victims still had all their teeth. However, the scans further showed that the teeth wore away, because they were used for cutting, orthodontist Dr ElisaVanacore said. Victims of Pompeii had Excellent teeth Tooth enamel is the hardest sub- stanceproducedbythehuman body.Sinceenamelisoneof the four major tissues that make up the teeth and gives them their distinctive shiny white appearance, it comesasasurprisethatastudy hasfoundthatenamelmostlikely originated from an entirely differ- ent part of the body:the skin. Unlike humans, who only have teeth inthemouth,certainfishspecieshave little tooth-like scales on the outer sur- face of the body.In the study,researchers from Uppsala University in Sweden and the In- stituteofVertebratePaleontologyandPaleoanthro- pology in Beijing in China analysed Lepisosteus,an ancient gar fish from North America whose scales are covered with an enamel-like tissue called ganoine. Their findings suggest that enamel in fact first evolved intheskin.DrPerAhlberg,Pro- fessor of Evolutionary Organ- ismal Biology at Uppsala Uni- versity, explained:“Psarolepis andAndreolepis are among the earliest bony fishes, so we be- lieve that their lack of tooth enamel is primitive and not a specialisation. It seems that enamel originated in the skin, where we call it ganoine, and only colonised the teeth at a later point.” The study is the first to combine novel palaeontological and genomic data in a sin- gle analysis to explore tissue evolution.The results havebeenpublishedonlineon23Septemberinthe Naturejournalinanarticletitled“Newgenomicand fossil data illuminate the origin of enamel”.
