Penetrating neck injury： Collaterals for another life after ligation of common carotid artery and subclavian artery

引用

Chinese Journal of Traumatology 2017年第1期20卷 56-58页

作者： Annu Babu Harshit garg Sushma Sagar Amit Gupta Subodh kumar Department of Surgery JPN Apex Trauma Centre All India Institute of Medical Science New Delhi India

Neck, being not protected by skeleton, is vulnerable to external trauma and injury which involves blood vessels, trachea, esophagus and other endocrine and nervous system organs. Vascular injuries can not only cause potentially, life-threatening hemorrhage but also need profound surgical expertise in man- agement. Development of collateral circulation in neck is well known： however, there is scarcity of literature on the role of collateral formation in neck trauma. Here, we present a unique case of pene- trating gunshot injury to neck with right common carotid and right subclavian artery injury with hemorrhagic shock managed with ligation of these vessels as a life-saving procedure. The patient pre- sented ~ith no neurological or motor de~,cits in immediate postoperative period owing to the collateral circulation between right vertebral artery and right common carotid and right subclavian artery.

Cosmetic arm lengthening with monorail fixator

引用

Chinese Journal of Traumatology 2015年第3期18卷 170-174页

作者： Hemendra kumar Agrawal Balvinder Singh Mohit garg Vipin Khatkar Sumit Batra Vinod kumar Sharma Central Institute of Orthopaedics. Safdarjung Hospital New Delhi 110029 India

Upper limb length discrepancy is a rare occurrence. Humerus shortening may need specialized treatment to restore the functional and cosmetic status of upper limb. We report a case of humerus lengthening of 9 cm with a monorail external fixator and the result was observed during a 2-year follow-up. Humerus lengthening needs specialized focus as it is not only a cosmetic issue but also a functional demand. The monorail unilateral fixator is more functional and cosmetically acceptable, and thus becomes an effective treatment option.

An unusual cause of radial nerve palsy

引用

Chinese Journal of Traumatology 2014年第3期17卷 175-177页

作者： Hemendra kumar Agrawal Vipin Khatkar Mohit garg Balvinder Singh Ashish Jaiman Vinod kumar Sharma Central Institute of Orthopedics VMMC andSafdarjung Hospital New Delhi 110029 India

Neurapraxia frequently occurs following traction injury to the nerve intraoperatively, leading to radial nerve palsy which usually recovers in 5-30 weeks. In our case, we had operated a distal one-third of humeral shaft fracture and fixed it with 4.5 mm limited contact dynamic compression plate. The distal neurovascular status of the limb was assessed postoperatively in the recovery room and was found to be intact and all the sensory-motor functions of the radial nerve were normal. On the second postoperative day, following the suction drain removal and dressing, patient developed immediate radial nerve palsy along with wrist drop. We reviewed the literature and found no obvious cause for the nerve palsy and concluded that it was due to traction injury to the radial nerve while removing the suction drain in negative pressure.

Novel CMS lines in pigeonpea[Cajanus cajan(L.)Millspaugh]derived from cytoplasmic substitutions,and their effective restoration and deployment in hybrid breeding

The availability of stable cytoplasmic male sterile(CMS or A) lines coupled with a robust restoration system(R lines) is an essential prerequisite for efficient hybrid ***-enabled hybrid technology holds immense potential to enhance the long-stagnant productivity of pigeonpea. In the present investigation, cytoplasmic substitutions were made in the nuclear backgrounds of early-maturing pigeonpea varieties or lines. Three new CMS lines(ICPL 88039 A, Pusa 992 A, and DPP 3-2A) resulted from genetic crosses involving cytoplasmic donors from A2(GT 288A) and A4(ICPA 2089) categories. In addition to visual inspection of anthers, pollen-staining techniques and scanning electron microscopy(SEM)analysis were used to confirm pollen sterility. Further, given the relevance of the plant mitochondrial genome to CMS manifestation, 25 mitochondrion-specific DNA markers were assayed on these newly developed A lines and isogenic maintainer(B) lines. DNA polymorphism between Pusa 992 A and Pusa 992 B as revealed by the nad7a_del marker confirmed the successful combination of sterilizing cytoplasm(A4) and nonrestoring nuclear background(Pusa 992). Such cytoplasm-specific DNA markers are required for A2-CMS as well. Further, to assess restoration ability, potential restorers were crossed with these CMS lines, and as a consequence, promising A × R combinations exhibiting 100%pollen fertility could be identified. In parallel, we also analyzed the inheritance patterns underlying fertility restoration using ICPL 88039A-derived F2 and BC1F1populations,and established a monogenic dominant model to explain the phenomenon of A2-CMS restoration. In summary, we report the successful development of new CMS lines and describe their effective deployment in hybrid breeding of pigeonpea.

mpaired flow-mediated vasodilatation in Asian Indians with erectile dysfunction

引用

Asian Journal of Andrology 2013年第5期15卷 652-657页

作者： Tanuj Bhatia Aditya Kapoor Jatinder kumar Archana Sinha Priyadarshi Ranjan Sudeep kumar Naveen garg Satyendra-Tewari Aneesh Srivastava Rakesh Kapoor Pravin K Goel Departments of Cardiology Sanjay Gandhi PGIMS Lucknow 226014 India Urology and Renal Transplantation Sanjay Gandhi PGIMS Lucknow 226014 India

Endothelial dysfunction is the postulated link between coronary artery disease （CAD） and erectile dysfunction （ED）. Brachial artery flow-mediated vasodilatation （FMD） is a non-invasive surrogate marker for endothelial function assessment. Despite Asian Indians representing a considerable global CAD burden, data on FMD and ED in these patients are lacking. Of the 225 patients undergoing coronary angiography, 72% had ED （assessed using the International Index of Erectile Function （IIEF-5） questionnaire）; ED was moderate to severe in 61% of the patients. ED patients had a higher incidence of severe and diffuse angiographic CAD, a greater number of coronary vessels involved and a lower mean brachial artery FMD （6.40%±4.60% vs. 9.10%±4.87%, P〈0.001） compared to non-ED patients. A progressive reduction in FMD was noted with increasing severity of ED. Impaired FMD （ ≤ 5.5%） was twice as common in ED patients （52% vs. 24% without ED）. Patients with impaired FMD had higher ED prevalence （85% vs. 62%） and lower mean I IEF-5 scores compared to those with normal FMD. Impaired FMD was a significant ED predictor independent of other risk factors （odds ratio, 2.33; 95% confidence interval： 0.59-9.23; P=0.03）. An inverse correlation between FMD and ED severity was observed （r=-0.22; P=0.004）. ED is common among Asian Indians with angiographically documented CAD. Patients with ED have impaired FMD independent of other risk factors, suggesting that endothelial dysfunction is the underlying pathophysiology. Urologists and cardiologists need to be aware of the association between ED, CAD and endothelial dysfunction.
