Trochanteric Flip (Ganz) Anterior Hip Dislocation for Fixation of Pipkin Fracture-Dislocations.

Safe surgical dislocation with a trochanteric flip osteotomy has been shown to be a reliable technique that provides excellent exposure for treating femoral-head fractures with minimal complications. This technique also allows associated labral injuries and acetabular fractures to be treated through the same approach. DESCRIPTION: The procedure is performed with use of a conventional Kocher-Langenbeck exposure with the patient in the lateral position. The trochanteric flip is performed, allowing exposure of the anterior capsule, which is incised to dislocate the head anteriorly. Fracture fixation is performed with use of mini-fragment screws followed by relocation of the head, closure of the capsulotomy, and fixation of the osteotomy. ALTERNATIVES: Fixation of femoral-head fractures can also be performed with use of alternate surgical approaches. Anterior-based surgical approaches like the Hueter approach or the Smith-Petersen approach are preferred with the goal of preserving the posterior extraosseous blood supply to the femoral head. The posterior Kocher-Langenbeck approach can also be utilized because there is no clear evidence suggesting that a properly performed posterior approach affects the blood supply of the femoral head. RATIONALE: Surgical hip dislocation is 1 of the preferred techniques for operative treatment of femoral-head fractures and is a versatile approach that provides circumferential exposure of the femoral head and acetabulum through an anterior dislocation. A compromised blood supply to the femoral head is much less likely with use of this approach compared with posterior-based surgical approaches. Compared with anterior-based surgical approaches, which are often restrictive, surgical dislocation is extensile and provides adequate exposure to treat associated injuries to the acetabulum and the labrum of the hip. EXPECTED OUTCOMES: Outcomes following surgical dislocation for femoral-head fractures are reportedly good to excellent in >80% patients. Urgent reduction of the hip joint followed by anatomical reduction of the fracture and stable fixation of the fracture and osteotomy leads to predictably good results. Notable complications include heterotopic ossification, which has been reported in up to 60% patients, as well as osteonecrosis of the femoral head (often related to the initial injury rather than the approach) and degenerative arthritis of the hip joint. IMPORTANT TIPS: The Gibson interval may be utilized to preserve the gluteus maximus.Identify all of the posterior structures starting proximally from the posterior border of the gluteus medius, and continuing to the piriformis, triceps coxae, quadratus femoris, and the vastus lateralis.Aim for a thickness of 1 to 1.5 cm when performing the osteotomy; an osteotomy that is either too thick or too thin can negatively affect outcomes. The osteotomy should begin just anterior to the posterior fibers of the gluteus medius to ensure that the osteotomy is anterior to the piriformis tendon. It should exit distally to the vastus lateralis origin.Carefully elevate the posterior margin of the gluteus minimis from the capsule to avoid the tethering effect during anterior translation of the osteotomized fragment.Capsular tears during the initial dislocation are common and should be incorporated into the anterior capsulotomy.Repair of large posterosuperior labral tears may improve outcomes.Fixation of the fracture can be performed with mini-fragment screws or headless screws. Non-fixable small fragments can be excised.The osteotomy should be reduced and fixed in a stable manner to prevent trochanteric nonunion and preserve abductor function.

Competency-based learning and training for medical postgraduates within regulatory guidelines in India: The SBV Competency-Based Learning and Training Model©.

Postgraduate medical education in India is beset with many problems including lack of a uniform national syllabus, nonexistence of an accepted list of competencies across disciplines, lack of uniformity in teaching/learning methods between different institutions, a poor evaluation system which focuses on a day's performance rather than the whole course and lack of attention to attitude and professionalism both in the training and evaluation processes. Since there is no national-level quality control of the outgoing postgraduates, there is no uniformity either in knowledge or skill level among them. Regulatory control over the whole process inhibits institutions from making any changes. Furthermore, the summative examination process is entirely under regulatory guidelines, with little or no option to universities and institutions to change the same. In this scenario, Sri Balaji Vidyapeeth, Puducherry, introduced and implemented a competency-based training programme for medical postgraduates, which is now in the 4th year. This model is suitable for the Indian milieu as it can be implemented within the regulatory guidelines. The model has been described with details of the processes involved in preparation, implementation, monitoring and overcoming possible hurdles and pitfalls in the Indian context.

Assessment of Self Perception of Competencies among a Group of Dental interns in Pondicherry, India.

CONTEXT: The general dentist must not only have a broad biomedical and clinical education but also be able to demonstrate professional and ethical behavior as well as effective communication and interpersonal skills. In addition he or she must have the ability to evaluate and utilize emerging technologies, continuing professional development opportunities, and problem-solving and critical thinking skills to effectively address current and future issues in health care. But the extent to which the core competencies are taught and the students' level of proficiency in these competencies in Indian scenario is to be explored at large. AIMS: The present study aims at assessing the self-perceived level of competencies and their importance for future practice and the extent to which the competencies are taught in the curriculum among interns of dental college in Pondicherry, India. SETTINGS AND DESIGN: The cross-sectional observational study was conducted among dental interns of Indira Gandhi Institute of Dental Sciences, Pondicherry. SUBJECTS AND METHODS: A total of 72 interns participated in the study. A short version of the Freiburg Questionnaire to Assess Competencies in Medicine" was used in this study. Questionnaire has three sections with same set of questions, which the student had to rate: (i) To what extent do you have the following competencies at your disposal? (ii) To what extent will your future job require the following competencies? and (iii) To what extent is competencies taught to you? After the results were obtained a focused group discussion with the responders was done. Focused group discussion consisted of open questions to the groups in all the four domains and the responses of the students were scribed. RESULTS: In all four domains, self-perceived level of competency was not satisfactory. However, all students stated that the competencies were highly relevant for their future practice. Despite this, most of the competencies are not taught to necessary extent in the curriculum. The results of the present survey revealed that the participating students perceived deficiencies in all domains of competencies. CONCLUSIONS: These results indicate that the core competencies are still barely integrated into dental curricula and that further research in this field is needed.

A comparison of the efficacy of naftopidil and tamsulosin hydrochloride in medical treatment of benign prostatic enlargement.

INTRODUCTION: Lower urinary tract symptoms in men, over age of 50 years is suggestive of benign prostatic enlargement (BPE). Different alpha-blockers have been evaluated for the treatment of benign prostatic hyperplasia for over last 30 years. This study was conducted in a tertiary care institution during the period of year between June 2011 and August 2013 to compare the effect of naftopidil and tamsulosin in reducing the obstructive and irritable symptoms of BPE. SUBJECTS AND METHODS: A prospective randomized comparative study was carried on 60 patients of BPE by assigning half of them to treatment with tamsulosin and rest with naftopidil. Pre- and post-treatment uroflowmetry (UFM), post-void residue (PVR), International Prostate Symptoms Score (IPSS), were obtained at 15 and 30 days after starting treatment. RESULTS: The age of patients ranged from 51 to 78. At base line there was no statistical difference between UFM parameter, PVR and IPSS in the two groups. UFM and PVR showed significantly better response at both intervals with naftopidil. Comparison of IPSS showed better improvement in Group A both at 15 and 30 days. It was seen that the obstructive symptoms showed a significantly better response with tamsulosin and symptoms of irritability was seen better response with naftopidil. CONCLUSION: It was seen that during the period of follow-up of 30 days naftopidil had a better effect on UFM, PVR, IPSS compared with tamsulosin. In general, obstructive symptoms showed better improvement in tamsulosin and irritative symptoms showed better improvement in naftopidil.

A hospital-based epidemiological study of corrosive alimentary injuries with particular reference to the Indian experience.

Corrosive alimentary tract injuries are a source of considerable morbidity all over the world. Despite this, actual data on the epidemiology of this problem are scarce mainly due to the lack of a well-established reporting system for poisoning in most countries. The burden of the disease is naturally more in countries such as India where the condition is common because of poor regulation of sale of corrosive substances. We analyse the available data on epidemiology of corrosive injuries, as well as patterns of involvement of the alimentary tract, with special reference to Indian data, and also provide an overview of the management options and long-term sequelae of this condition.

Is Helicobacter pylori Infection the Primary Cause of Duodenal Ulceration or a Secondary Factor? A Review of the Evidence.

Helicobacter pylori (H. pylori) has a role in the multifactorial etiology of peptic ulcer disease. A link between H. pylori infection and duodenal ulcer disease is now established. Other contributing factors and their interaction with the organism may initiate the ulcerative process. The fact that eradication of H. pylori infection leads to a long-term cure in the majority of duodenal ulcer patients and the fact that the prevalence of infection is higher in ulcer patients than in the normal population are cogent arguments in favor of it being the primary cause of the ulceration. Against this concept there are issues that need explanation such as the reason why only a minority of infected persons develop duodenal ulceration when infection with H. pylori is widespread. There is evidence that H. pylori infection has been prevalent for several centuries, yet duodenal ulceration became common at the beginning of the twentieth century. The prevalence of duodenal ulceration is not higher in countries with a high prevalence of H. pylori infection. This paper debate puts forth the point of view of two groups of workers in this field whether H. pylori infection is the primary cause of duodenal ulcer disease or a secondary factor.

ICMR's ethical guidelines for biomedical research on human participants: need for clarification.

The "Ethical guidelines for biomedical research on human participants" prepared by the Indian Council of Medical Research in 2006 came as a welcome step in the process of regulation of research on human subjects, since clear cut Indian guidelines were absent earlier. The guidelines have been accepted as the standard operating manual by Institutional Ethics Committees (IEC) in India. However, over a period of time, it has become obvious that the guidelines lack clarity in certain areas and require to be revised in the light of experiences of members in the IECs. Some of these problems with the ICMR guidelines have been highlighted in this paper to press for revision of the manual in the light of these experiences.

Is there need for a transformational change to overcome the current problems with postgraduate medical education in India?

In spite of the existence of a dual system of postgraduation, one under the Medical Council of India (MCI) and the other on a parallel track under the National Board of Examinations, postgraduate medical education in India is beset with several problems. For example, the curriculum has not been revised comprehensively for several decades. The diploma course under the MCI has become unpopular and is largely a temporary refuge for those who do not get admission to degree courses. The level of skills of the outgoing graduate is falling and the increase in the number of seats is taking place in a haphazard manner, without reference to the needs. In spite of increase in seats, there is a shortage of specialists at the secondary and tertiary care levels, especially in medical colleges, to share teaching responsibilities. Further, the distribution of specialists is skewed, with some states having far more than others. To remedy these ills and fulfil the requirements of the country over the next two decades, a working group appointed by the erstwhile governors of the MCI was asked to suggest suitable modifications to the existing postgraduate system. After an extensive review of the lacunae in the present system, the needs at various levels and the pattern of postgraduate education in other countries, it was felt that a competency-based model of a 2-year postgraduate course across all specialties, the use of offsite facilities for training and a criterion-based evaluation system entailing continuous monitoring would go a long way to correct some of the deficiencies of the existing system. The details of the proposal and its merits are outlined for wider discussion and to serve as a feedback to the regulatory agencies engaged in the task of improving the medical education system in India. We feel that the adoption of the proposed system would go a long way in improving career options, increasing the availability of teachers and dissemination of specialists to the secondary and primary levels, and improving the quality of outgoing postgraduates.

Acute corrosive injuries of the stomach: a single unit experience of thirty years.

Introduction. The spectrum of gastric injury due to corrosives can vary. This paper presents a single center experience of over 30 years of corrosive gastric injuries of 39 patients with acute gastric injuries from 1977 till 2006. Patients and Methods. Two thirds of the patients in the acute injury group had a concomitant esophageal injury. The age of the patients ranged from 4 years to 65 years with a slight preponderance of males. (M : F ratio 22 : 17). Results. 36 out of 39 acute gastric injuries were due to ingestion of acids. Three patients had history of caustic soda ingestion. Oral hyperemia or ulcers of varying extent were seen in all patients. The stomach showed hyperemia in 10, extensive ulcers in 13, and mucosal necrosis in 10 patients. Fifteen patients (15/39, 38.5%) were managed conservatively. Twenty four patients (24/39, 61.5%) underwent laparotomy: one for frank peritonitis, 10 for gastric mucosal necrosis, and 13 others for extensive gastric ulcerations. Overall the mortality rate was 29.6 %. Conclusion. Although the mortality and morbidity of acute corrosive gastric injuries is high, the key to improve the survival is early identification of perforation, maintenance of nutrition and control of sepsis.

Diagnostic value of C-reactive protein in suspected acute appendicitis--a prospective case control study.

AIM: To find out the Sensitivity, Specificity and Predictive value of C-reactive protein in the diagnosis of acute appendicitis. MATERIALS AND METHODS: Hundred patients undergoing emergency appendicectomy were cases and thirty patients undergoing interval appendicectomy during the same period were controls. Creactive protein was measured pre-operatively. RESULTS: CRP was reactive in 89% of cases and 3 of 30 controls (P = 0). Among the thirteen complicated cases, two had a CRP reactivity of 1.2 mg/dl, eight had 2.4 mg/dl and three had 3.6 mg/dl. In the uncomplicated cases, forty nine were reactive at 1.2 mg/dl, twenty six at 2.4 mg/dl and one at 3.6 mg/dl (P = 0.0009). In histopathologically inflamed appendix, reactivity was 94.4% and in normal appendix reactivity was 40% (P = 0.00007). CRP positivity had a sensitivity of 94.4% (CI 89.9-98.9) and a positive predictive value of 95.5% (CI 91.4-99.6). CRP reactivity and leucocytosis if combined, the sensitivity, specificity, PPV and NPV were 85%, 100%, 100% and 81% respectively. Threshold for CRP reactivity if raised to 2.4 mg/dl, the sensitivity, specificity, PPV and NPV are 42%, 100%, 100% and 16% respectively. CONCLUSION: CRP estimation is a good 'rule-in' test and not-so-good 'rule-out' test to diagnose acute appendicitis.
