| 1 | Developmental dysplasia of the hip in the newborn: A systematic review显示文摘Developmental dysplasia of the hip(DDH) denotes a wide spectrum of conditions ranging from subtle acetabular dysplasia to irreducible hip dislocations. Clinical diagnostic tests complement ultrasound imaging in allowing diagnosis, classification and monitoring of this condition. Classification systems relate to the alpha and beta angles in addition to the dynamic coverage index(DCI). Screening programmes for DDH show considerable geographic variation; certain risk factors have been identified which necessitate ultrasound assessment of the newborn. The treatment of DDH has undergone significant evolution, but the current gold standard is still the Pavlik harness. Duration of Pavlik harness treatment has been reported to range from 3 to 9.3 mo. The beta angle, DCI and the superior/lateral femoral head displacement can be assessed via ultrasound to estimate the likelihood of success. Success rates of between 7% and 99% have been reported when using the harness to treat DDH. Avascular necrosis remains the most devastating complication of harness usage with a reported rate of between 0% and 28%. Alternative non-surgical treatment methods used for DDH include devices proposed by LeD amany, Frejka, Lorenz and Ortolani. The Rosen splint and Wagner stocking have also been used for DDH treatment. Surgical treatment for DDH comprises open reduction alongside a combination of femoral or pelvic osteotomies. Femoral osteotomies are carried out in cases of excessive anteversion or valgus deformity of the femoral neck. The two principal pelvic osteotomies most commonly performed are the Salter osteotomy and Pemberton acetabuloplasty. Serious surgical complications include epiphyseal damage, sciatic nerve damage and femoral neck fracture. | Vivek Gulati Kelechi Eseonu Junaid Sayani Nizar Ismail Chika Uzoigwe Muhammed Zaki Choudhury Pooja Gulati Adeel Aqil Saket Tibrewal | 2013 | World Journal of Orthopedics2013，4，2： | 29 |
| 2 | Diagnosis of Helicobacter pylori : What should be the gold standard?显示文摘Since the discovery of Helicobacter pylori(H. pylori) in 1983, numerous detection methods for the presence of the bacterium have been developed. Each one of them has been associated with advantages and disadvantages. Noninvasive tests such as serology, 13 C urea breath test(UBT) and stool antigen tests are usually preferred by the clinicians. Serology has its own limitation especially in endemic areas while 13 C UBT is technically very demanding. The stool antigen detection method, although specific, is usually associated with poor sensitivity. The 13 C UBT is believed to be specific, but with present revelation of the fact that stomach is colonized by many other urease producing bacteria makes it questionable. Histology, culture, rapid urease test and polymerase chain reaction(PCR) are the tests which are carried out on antral biopsies collected by invasive means. Histology has been proposed to be very sensitive and specific but the question is how by simply looking the morphology of the bacteria in the microscope, one can claim that the curved bacterium is exclusively H. pylori. Rapid urease test(RUT), the doctor's test, is also challenged because the presence of other urease producing bacteria in the stomach cannot be denied. Moreover, RUT has been reported with poor sensitivity specially, when density of the bacterium is low. Isolation of H. pylori is essential to investigate its growth requirements, antibiotic susceptibility testing, studying virulence factor to develop vaccine and many more explorations. It has also got several disadvantages i.e., special condition for transporting, media, incubation and few days waiting for the colonies to appear, apart from the speed essentially needed to process the specimens. Till date, majority of the microbiological laboratories in the world are not equipped and trained to isolate such fastidious bacterium. The option left is PCR methods to detect H. pylori 's DNA in gastric mucosa, gastric juice, saliva, dental plaques and environmental specimens. There are speculations for false positivity due to detection of non-pylori Helicobacters due to genetic sharing; and false negativity due to low bacterial counts and presence of PCR inhibitors. However, specimen collection, transportation and processing do not require speed and special conditions. PCR based diagnosis may be considered as gold standard by designing primers extremely specific to H. pylori and targeting at least more than one conserved genes. Similarly specificity of PCR may be improved by use of internal Primers. Further, nested PCR will take care of false negatives by countering the effect of PCR inhibitors and low bacterial counts. Therefore, nested PCR based methods if performed properly, may be proposed as gold standard test. | Saurabh Kumar Patel Chandra Bhan Pratap Ashok Kumar Jain Anil Kumar Gulati Gopal Nath | 2014 | World Journal of Gastroenterology2014，20，36： | 30 |
| 3 | Role of bacteria in carcinogenesis, with special reference to carcinoma of the gallbladder显示文摘Carcinoma of the gallbladder (CaGB) is the fifth commonest gastrointestinal tract cancer and is endemic in several countries. The interplay of genetic susceptibility, infections, and life style factors has been proposed to be responsible for carcinogenesis of gallbladder. Persistence of infection leading to chronic inflammation, and production of certain toxins and metabolites with carcinogenic potentials, by certain bacteria has been speculated to be involved in the transformation of the gallbladder epithelium. Therefore, any bacteria that have evolved to acquire both of the above carcinogenic mechanisms can cause cancer. Salmonella typhi has been found to be prominently associated with CaGB. Chronic typhoid carriage (persistence) and production of mediators of chronic infl ammation and a genotoxic toxin (cytotoxic distending toxin, CdtB) are also known for this bacterium. Furthermore, the natural concentrating function of the gallbladder might amplify the carcinogenic effect of the mediators of carcinogenesis. In addition to S. typhi, certain species of Helicobacter (H. bilis and H. hepaticus) and Escherichia coli have also been implicated in carcinogenesis. As the isolation rate is verypoor with the presently available culture techniques, the existence of bacteria in a viable but non-cultivable state is quite likely; therefore, sensitive and specif ic molecular techniques might reveal the etiological role of bacterial infection in gallbladder carcinogenesis. If bacteria are found to be causing cancers, then eradication of such infections might help in reducing the incidence of some cancers. | Gopal Nath Anil K Gulati Vijay K Shukla | 2010 | World Journal of Gastroenterology2010，16，43： | 12 |
| 4 | Associating liver partition and portal vein ligation for staged hepatectomy: From technical evolution to oncological benefit显示文摘Associating liver partition and portal vein ligation for staged hepatectomy(ALPPS) is a novel approach in liver surgery that allows for extensive resection of liver parenchyma by inducing a rapid hypertrophy of the future remnant liver. However,recent reports indicate that not all patients eligible for ALPPS will benefit from this procedure. Therefore,careful patient selection will be necessary to fully exploit possible benefits of ALPPS. Here,we provide a comprehensive overview of the technical evolution of ALPPS with a special emphasis on safety and oncologic efficacy. Furthermore,we review the contemporary literature regarding indication and benefits,but also limitations of ALPPS. | Jun Li Florian Ewald Amit Gulati Bjon Nashan | 2016 | World Journal of Gastrointestinal Surgery2016，8，2： | 9 |

| 6 | Management of achilles tendon injury: A current concepts systematic review显示文摘Achilles tendon rupture has been on the rise over recent years due to a variety of reasons. It is a debilitating injury with a protracted and sometimes incomplete recovery. Management strategy is a controversial topic and evidence supporting a definite approach is limited. Opinion is divided between surgical repair and conservative immobilisation in conjunction with functional orthoses. A systematic search of the literature was performed. Pubmed, Medline and EmB ase databases were searched for Achilles tendon and a variety of synonymous terms. A recent wealth of reporting suggests that conservative regimens with early weight bearing or mobilisation have equivalent or improved rates of re-rupture to operative regimes. The application of dynamic ultrasound assessment of tendon gap may prove crucial in minimising re-rupture and improving outcomes. Studies employing functional assessments have found equivalent function between operative and conservative treatments. However, no specific tests in peak power, push off strength or athletic performance have been reported and whether an advantage in operative treatment exists remains undetermined. | Vivek Gulati Matthew Jaggard Shafic Said Al-Nammari Chika Uzoigwe Pooja Gulati Nizar Ismail Charles Gibbons Chinmay Gupte | 2015 | World Journal of Orthopedics2015，6，4： | 5 |
| 7 | Imaging in pulmonary hydatid cysts显示文摘Hydatid disease is a zoonosis that can involve almost any organ in the human body. After the liver, the lungs are the most common site for hydatid disease in adults. Imaging plays a pivotal role in the diagnosis of the disease, as clinical features are often nonspecific. Classical radiological signs of pulmonary hydatid cysts have been described in the literature, aiding in the diagnosis of the disease. However, complicated hydatid cysts can prove to be a diagnostic challenge at times due to their atypical imaging features. Radiography is the initial imaging modality. Computed tomography can provide a specific diagnosis in complicated cases. Ultrasound is particularly useful in peripheral lung lesions. The role of magnetic resonance imaging largely remains unexplored. | Mandeep K Garg Madhurima Sharma Ajay Gulati Ujjwal Gorsi Ashutosh N Aggarwal Ritesh Agarwal Niranjan Khandelwal | 2016 | World Journal of Radiology2016，8，6： | 4 |

| 9 | 冲破组织壁垒直达客户需求显示文摘如今,市场经济的许多领域都呈现出买方市场的特征,而买方市场与卖方市场的最大不同就是消费者选择权的大大增加。这无疑给供应商和销售商制造了难题,它们必须摆脱“以产品为中心”的传统思维,转而采取“以客户为中心”的全新观念。然而,许多公司虽然声称自己将客户放在了首要位置,却不懂得从客户的立场去分析问题,帮助客户解决问题。因而,所谓“客户导向”也不过是一句空洞的口号。
在《冲破组织壁垒直达客户需求》中我们看到,为了从日趋同质化的市场中脱颖而出,许多公司开始从卖产品转向卖解决方案。但是,在实行这一转变的过程中,它们往往并未以客户为中心。事实上,各个部门各自为政,能力局限,很难利用跨部门的资源来推出客户真正看重而且愿意花钱购买的解决方案。因此,作者提出,需在公司内部建立协调机制、打破组织内外部边界、培养跨边界工作的能力、创建一个真正以客户为轴心的新型组织。 | 兰杰·古拉蒂(Ranjay Gulati) | 2007 | 商业评论2007，，7： | 2 |
