RESUMEN
BACKGROUND: Preclinical students often fail to appreciate the clinical relevance of basic sciences during the first year of undergraduate medical training, leading them to lose interest in the subject, and preventing them from achieving the desired goals. In order to rectify this gap in the curriculum, Medical Council of India (MCI) in 2011 published a document announcing curricular strategies including Early Clinical Exposure (ECE) to effectively modify the Indian system of education. Lack of proper guidance prevented many institutions from implementing ECE. Since our institution had run a similar program of "Clinical Observership" as early as 2001, we were able to implement ECE in an efficient way. MATERIALS AND METHODS: Early clinical exposure was implemented as a structured program, with the participation of 10 clinical departments since 2013. Feedback from the students, soon after ECE and also from the batch of CRRIs, who had undergone this program while they were preclinical students amply support the effectiveness of ECE in its contents and methods of implementation. Manual content analysis was performed on open comments. After reading the responses, they were broken down to meaning units, and these were then condensed. The condensed meaning units were labeled with codes. The codes were grouped into categories. Themes were derived from the categories. RESULTS: Out of the 70 CRRIs, 52 responded to the questionnaire. All the CRRIs except one said that ECE was very helpful during their clinical postings and internship period. They suggested that the number of hours of posting should be increased and also reiterated the fact that a greater number of clinical departments could be included in the program. Though the beneficial effects were felt in all the domains of learning, the most remarkable impact was felt in the affective domain, wherein changes are not easy to come by. DISCUSSION: Recently, National Medical Council has come out with plans of including ECE in the syllabus with strict time schedule. It is felt that the faculty will find our experience of running the program for the past five years helpful in implementing this program, for the fullest benefit of the preclinical students.
RESUMEN
A case of accessory scrotum in a 2-day-old male infant is reported because of its rarity. An overview of sequences during the normal development of male external genitalia has been provided and the deranged mechanism resulting in this anomaly has been reviewed with hypotheses regarding etiology of accessory scrotum.
RESUMEN
OBJECTIVES: In order to increase their effectiveness, methods of teaching morphological sciences need to be revised to incorporate the recent technological advances made in the field of medicine. Teaching human structure with conventional methods of prosections using dissected cadaveric specimen alone quite often fails to prepare students adequately for their clinical training. A learner-oriented method, incorporating three dimensional spatial anatomy and more closely mirroring the clinical setting, is required. METHODS: With these challenges in mind, a 30-minute slow-paced video recording of a cholecystectomy performed laproscopically on a 45 year-old lady was adapted to supplement the conventional teaching of anatomy of the abdomen and pelvis. This study was carried out in October 2010. RESULTS: The subjects of this study were 84 students in a first year preclinical MD course in human structure at the private Oman Medical College. Their feedback was obtained via questionnaire and revealed that the video presentation helped the students to realise the significance of the anatomical details learnt during the human structure course. CONCLUSION: Recordings of laparoscopic surgeries are an effective preclinical anatomy teaching resource in student-centred learning. They also help the students to appreciate the clinical relevance of gross anatomy and enhance their motivation to learn.
RESUMEN
BACKGROUND: Adult patients with idiopathic hypogonadotropic hypogonadism (IHH) typically present with absent puberty and therefore have prepubertal testes. IHH is recognized as one of the few curable causes of male infertility and is often effectively treated with either gonadotropins or pulsatile GnRH therapy. The objective of this study was to determine the structure of the testis prior to initiation of treatment. METHODS AND RESULTS: Eight adult IHH patients with prepubertal testes (<4 ml), with no previous gonadotropin therapy and with no history of cryptorchidism underwent open bilateral testicular biopsy prior to the initiation of hormonal treatment. The testes of all patients showed seminiferous cords separated by interstitium composed of blood vessels, connective tissue cells and collagen fibres but typical adult Leydig cells were absent. The cords contained only Sertoli cells and early type A spermatogonia. The spermatogonia mostly resided in the centre of the cords and were often large, typical of gonocytes. Sertoli cells appeared immature with ovoid nuclei devoid of infoldings and cytoplasm that lacked polarity. Tight junctional complexes commonly found connecting adult Sertoli cells were lacking. CONCLUSIONS: These results demonstrate that the immature testes from patients with the severe form of IHH possess early spermatogonia that could possibly reinitiate spermatogenesis with appropriate hormone stimulation. Therefore, the immature testis of this IHH subset resembles those of prepubertal boys and may provide important biologic and genetic insights into testicular development.
