Craniometrics and Ventricular Access: A Review of Kocher'S, Kaufman'S, Paine'S, Menovksy'S, Tubbs', Keen'S, Frazier'S, Dandy'S, and Sanchez'S Points
Oper Neurosurg (Hagerstown) 2020 May 1;18(5):461-469.PMID:31420653DOI:10.1093/ons/opz194.
Intraventricular access is frequently required during neurosurgery, and when neuronavigation is unavailable, the neurosurgeon must rely upon craniometrics to achieve successful ventricular cannulation. In this historical review, we summarize the most well-described ventricular access points: Kocher'S, Kaufman'S, Paine'S, Menovksy'S, Tubbs', Keen'S, Frazier'S, Dandy'S, and Sanchez'S. Additionally, we provide multiview, 3-dimensional illustrations that provide the reader with a novel understanding of the craniometrics associated with each point.
Finkelstein'S Test Is Superior to Eichhoff'S Test in the Investigation of de Quervain'S Disease
J Hand Microsurg 2018 Aug;10(2):116-118.PMID:30154628DOI:10.1055/s-0038-1626690.
Introduction de Quervain'S tenosynovitis is a common pathologic condition of the hand. Finkelstein'S test has long been considered to be a pathognomonic sign of this diagnosis, yet most clinicians and instruction manuals erroneously describe what is in fact the Eichhoff'S test, which is thought to produce similar pain by tendon stretching in a normal wrist. The purpose of this study was to compare Finkelstein'S test with Eichhoff'S test in asymptomatic individuals. Materials and Methods Thirty-six asymptomatic participants (72 wrists) were examined using both Finkelstein'S and Eichhoff'S tests with a minimum interval of 24 hours between the tests. Results The results showed that Finkelstein'S test was more accurate than Eichhoff'S test. It demonstrated higher specificity, produced significantly fewer numbers of false-positive results, and also caused significantly less discomfort to patients. Conclusion This study recommends Finkelstein'S test as the clinical examination of choice for the diagnosis of de Quervain'S disease.
Impact of sporadic reporting of poultry Salmonella serovars from selected developing countries
J Infect Dev Ctries 2015 Jan 15;9(1):1-7.PMID:25596565DOI:10.3855/jidc.5065.
This review documents the sporadic reporting of poultry Salmonella serovars in South Africa, Egypt, Indonesia, India, and Romania, five countries selected based on the importance of their distribution in different regions of the world and their cumulative significant population size of 1.6 billion. South Africa reported contamination of its poultry carcasses by S. Hadar, S. Blockley, S. Irumu, and S. Anatum. Results from Egypt showed that S. Enteritidis and S. Typhimurium were predominant in poultry along with other non-typhoid strains, namely S. Infantis, S. Kentucky, S. Tsevie, S. Chiredzi, and S. Heidelberg. In Indonesia, the isolation of Salmonella Typhi was the main focus, while other serovars included S. Kentucky, S. Typhimurium, and S. Paratyhi C. In India, S. Bareilly was predominant compared to S. Enteritidis, S. Typhimurium, S. Paratyphi B, S. Cerro, S. Mbandaka, S. Molade, S. Kottbus, and S. Gallinarum. Romania reported two Salmonella serovars in poultry that affect humans, namely S. Enteritidis and S. Typhimurium, and other non-typhoid strains including S. Infantis, S. Derby, S. Colindale, S. Rissen, S. Ruzizi, S. Virchow, S. Brandenburg, S. Bredeney, S. Muenchen, S. Kortrijk, and S. Calabar. The results showed the spread of different serovars of Salmonella in those five developing countries, which is alarming and emphasizes the urgent need for the World Health Organization Global Foodborne Infections Network (WHO-GFN) to expand its activities to include more strategic participation and partnership with most developing countries in order to protect poultry and humans from the serious health impact of salmonellosis.
Static and fatigue tensile properties of carbon/glass hybrid fiber-reinforced epoxy composites
Sci Rep 2022 Apr 15;12(1):6298.PMID:35428749DOI:10.1038/s41598-022-10245-5.
The static and fatigue tensile properties of high-strength polyacrylonitrile (PAN)-based carbon (IMS60) and electronic (E)-class glass (E-glass) hybrid fiber-reinforced epoxy matrix composites (HFRPs) were investigated. The fiber orientations of the HFRP specimens were set to unidirectional with [(0(IMS60))/(0(E-glass))]S (subscript S means symmetry and [(0(IMS60))/(0(E-glass))/(0(E-glass))/(0(IMS60))]), [(0(E-glass))/(0(IMS60))]S, [(0(E-glass))/(0(IMS60))2]S, [(0(E-glass))/(0(IMS60))3]S, [(0(E-glass))/(0(IMS60))5]S, [(0(E-glass))2/(0(IMS60))]S, [(0(E-glass))3/(0(IMS60))]S, and [(0(E-glass))5/(0(IMS60))]S. Under static loading for the [(0(IMS60))/(0(E-glass))]S, [(0(E-glass))/(0(IMS60))]S, [(0(E-glass))/(0(IMS60))2]S, [(0(E-glass))/(0(IMS60))3]S, and [(0(E-glass))/(0(IMS60))5]S HFRP specimens, the stress applied to the specimen was almost linearly proportional to the strain until failure. However, the tensile stress-strain curves of the [(0(E-glass))2/(0(IMS60))]S, [(0(E-glass))3/(0(IMS60))]S, and [(0(E-glass))5/(0(IMS60))]S HFRP specimens had a complicated shape (jagged trace). The Weibull statistical distributions of the tensile strength values were also examined. The Weibull moduli for the [(0(E-glass))/(0(IMS60))]S, [(0(E-glass))/(0(IMS60))2]S, [(0(E-glass))/(0(IMS60))3]S, [(0(E-glass))/(0(IMS60))5]S, [(0(E-glass))2/(0(IMS60))]S, [(0(E-glass))3/(0(IMS60))]S, and [(0(E-glass))5/(0(IMS60))]S HFRP specimens were higher than those for the mono carbon fiber-reinforced epoxy (CFRP) and glass fiber-reinforced epoxy (GFRP) specimens. Under fatigue loading, the fatigue properties of the HFRP specimens showed CFRP-dominant behaviour at high stress levels and GFRP-dominant behaviour at low stress levels. The fatigue properties of the HFRP specimens increased with increasing volume fraction of CFRP in the following order: ([(0(E-glass))/(0(IMS60))5]S > [(0(E-glass))/(0(IMS60))3]S > [(0(E-glass))/(0(IMS60))2]S > [(0(IMS60))/(0(E-glass))]S > [(0(E-glass))/(0(IMS60))]S > [(0(E-glass))2/(0(IMS60))]S > [(0(E-glass))3/(0(IMS60))]S > [(0(E-glass))5/(0(IMS60))]S).
A review of the genus Scrobipalpa Janse, 1951 (Lepidoptera, Gelechiidae) in the Afrotropical region
Zootaxa 2021 Nov 19;5070(1):1-83.PMID:34810684DOI:10.11646/zootaxa.5070.1.1.
The genus Scrobipalpa in the Afrotropical region is revised. Thirty-six species are recognized as valid, 20 of which are described as new: S. ochroxantha sp. nov. (South Africa), S. wieseri sp. nov. (Namibia, South Africa), S. turiensis sp. nov. (Kenya), S. wolframi sp. nov. (Namibia), S. natalensis sp. nov. (South Africa), S. varivansoni sp. nov. (South Africa), S. typica sp. nov. (South Africa), S. staudei sp. nov. (South Africa), S. afromontana sp. nov. (Kenya), S. erexita sp. nov. (South Africa), S. admirabilis sp. nov. (Namibia), S. griseata sp. nov. (South Africa), S. nigristriana sp. nov. (Kenya), S. munita sp. nov. (Malawi), S. ochracea sp. nov. (South Africa), S. asantesana sp. nov. (South Africa), S. selectoides sp. nov. (Namibia, RSA), S. etoshensis sp. nov. (Namibia), S. ethiopica sp. nov. (Ethiopia), and S. agassizi sp. nov. (Kenya). Six new synonyms are established: Phthorimaea blapsigona Meyrick, 1916 and Scrobipalpa asiri Povoln, 1980 syn. nov. of Scrobipalpa concreta (Meyrick, 1914); Scrobipalpa xylochroa Janse, 1963 and S. obsoletella hospes Povoln, 1964 syn. nov. of S. obsoletella (Fischer von Rslerstamm, 1841); S. vicaria (Meyrick, 1921) syn. nov. of S. geomicta (Meyrick, 1918); and Gelechia chersophila Meyrick, 1918 syn. nov. of S. portosanctana (Stainton, 1859). The following new combinations for five species previously placed in Scrobipalpa are proposed: Ephysteris cretigena (Meyrick, 1914) comb. nov., Microlechia colasta (Meyrick, 1921) comb. nov., Schizovalva costimacula (Janse, 1951) comb. nov., Gelechia trychnophylla (Janse, 1960) comb. nov. and Trychnopalpa phalacrodes (Meyrick, 1913) comb. nov. Two species, Phthorimaea pendens Meyrick, 1918 comb. rev. and Homaloxestis ocyphanes Meyrick, 1937 comb. rev., are excluded from Scrobipalpa but no current genus is available. The male genitalia of Scrobipalpa nomias (Meyrick, 1921) are described for the first time. All species are diagnosed, some of them are redescribed based on additional material. Identification keys and photographs of adults and genitalia are provided. New or additional host plants are recorded for Scrobipalpa incola (Meyrick, 1912), S. concreta, S. portosanctana, and S. ergasima (Meyrick, 1916). Scrobipalpa incola is recorded for the first time from Namibia, Tanzania, and Kenya; S. concreta is new for Ethiopia, Sudan, Tanzania, Kenya, Mozambique, Benin and Mauritius; S. subroseata for Tanzania and Kenya; S. aptatella (Walker, 1864) and S. biljurshi Povoln, 1980 for Ethiopia; S. obsoletella and S. traganella (Chrtien, 1915) for Namibia; S. geomicta for India and Ethiopia; and S. ergasima for Benin, Zimbabwe, Tanzania, Ethiopia, and Yemen.
