ABSTRACT
BACKGROUND: Cleft lip and palate is one of the most common congenital craniofacial deformities seen in children. Various congenital anomalies are reported in the literature to be associated with cleft lip and palate. Cardiac anomalies are one of the most common congenital disorders associated in cleft lip and palate patientsIt includes Cyanotic and acyanotic cardiac diseases likel fallot's tetralogy, transposition of greater vessels, atresia of tricuspid, total anomalous pulmonary venous return (TAPVR), truncus arteriosus, ebstein's anomaly, hypoplastic left heart syndrome and pulmonary atresia, patent ductus arteriosus, ventricular septal defect, atrial septal defect, pulmonary stenosis, aortic stenosis and coarctation of aorta. AIM: To study the prevalence of congenital cardiac anomalies in cleft lip and palate patients. OBJECTIVES: To study different types of congenital cardiac anomalies/defects in patients with cleft lip and palate and its implications in surgical management. MATERIALS AND METHODS: This is a retrospective study carried out for a period of one year. In the present study medical records of 200 patients with cleft lip and palate were evaluated and analyzed for presence of congenital cardiac anomalies. RESULTS: Out of 200 patients of cleft lip and palate, 30 patients (15%) were associated with congenital cardiac anomalies with male to female ratio of 1:1. Associated congenital cardiac anomalies were most frequently seen in unilateral cleft palate patients (21.05%) The most common cardiac anomaly was Ventricular septal defect (36.6%).
ABSTRACT
Despite a paradigm shift in anesthesia and trauma airway management, the craniomaxillofacial fracture (CMF) patients continue to pose a challenge. A prospective study was planned between April 2007 and March 2015 to investigate the safety, efficacy, utility, and complications of anterior submandibular approach for transmylohyoid intubation (TMI) in CMFs using an armored endotracheal tube (ETT). Out of 1,207 maxillofacial trauma cases reported, this study recruited 206 patients (152 males and 54 females) aged between 21 and 60 years. No episode of oxygen desaturation was noted intraoperatively. Mean time to perform TMI was 6 ± 2 minutes. The mean transmylohyoid ETT withdrawal time/disconnection time from ventilator was approximately 1.5 minutes. Accidental partial extubation of ETT was noted in two patients (0.97%), and three patients (1.45%) developed abscess formations at anterior submandibular site which were managed by incision and drainage. The anterior submandibular approach for TMI was successfully used and provided stable airway in all elective CMF surgery cases, where oral or nasal intubations were not indicated/feasible and long-term ventilation support was not required. It permitted simultaneous dental occlusion-guided reduction and fixation of all the facial fractures without interference from the tube during the surgery with unhindered maintenance of the anesthesia and airway. The advantages include easy, swift, efficient, and reliable approach with a small learning curve.
ABSTRACT
The value of coronal incisions in maxillofacial surgery has been well documented. The incision provides excellent access to the upper facial skeleton aiding in adequate access, good anatomic reduction of fractures and hidden scar. The associated bleeding with raising a bicoronal flap is a matter of concern to beginner surgeons. This often prevents the regular use of this approach. Textbooks have recommended the use of Raney clips but these are not available routinely in India and are expensive. We have utilized simple stationary paper clips, autoclaved and used for surgery. This not only provide haemostasis but also aids in holding the flap during dissection. This technique would be of great help to young surgeons and in developing countries where economics plays a major role in surgery.
ABSTRACT
The appearance and cooking quality of rice determine its acceptability and price to a large extent. Quantitative trait loci (QTLs) for 12 grain quality traits were mapped in 2 mapping populations derived from Oryza sativa cv Swarna × O. nivara. The BC(2)F(2) population of the cross Swarna × O. nivara IRGC81848 (population 1) was evaluated during 2005 and that from Swarna × O. nivara IRGC81832 (population 2) was evaluated during 2006. Linkage maps were constructed using 100 simple sequence repeat (SSR) markers in population 1 and 75 SSR markers in population 2. In all, 21 QTLs were identified in population 1 (43% from O. nivara) and 37 in population 2 (38% QTLs from O. nivara). The location of O. nivara-derived QTLs mp1.2 for milling percent, kw6.1 for kernel width, and klac12.1 for kernel length after cooking coincided in the 2 populations and appear to be useful for Marker Assisted Selection (MAS). Four QTLs for milling percent, 1 QTL each for amylose content, water uptake, elongation ratio, 2 QTLs for kernel width, and 3 QTLs for gel consistency, each explained more than 20% phenotypic variance. Three QTL clusters for grain quality traits were close to the genes/QTLs for shattering and seed dormancy. QTLs for 4 quality traits were associated with 5 of the 7 major yield QTLs reported in the same 2 mapping populations. Useful introgression lines have been developed for several agronomic traits. It emerges that 40% O. nivara alleles were trait enhancing in both populations, and QTLs for grain quality overlapped with yield meta-QTLs and QTLs for dormancy and seed shattering.
