Placenta is a unique organ which arise de novo, directly related to the growth and development of the foetus in the uterus. A thorough examination of the placenta inutero, as well as post-partum, gives valuable information about the state of the foetal well being. Pregnancy Induced Hypertension is a well recognized obstetric hazard and observed more frequently in developing countries. OBJECTIVES: The present study was undertaken to analyze placental changes in the pregnancy induced hypertension. MATERIAL AND METHODS: thirty placentae of mothers with uncomplicated pregnancy as control group and thirty with pregnancy induced hypertension as study group were studied with gross examination and histologically. RESULTS: Gross examination revealed presence of smaller placentae with foci of calcification and infarction in study group. On light microscopic examination, the striking villous abnormalities were observed in the study group which included increased Syncytial knots formation, fibrinoid necrosis, stromal fibrosis, hyalinized villi, altered villous vascularity (hypo vascularity), cytotrophoblastic cell proliferation, endarteritis obliterans, intervillous haemorrhage and basement membrane thickening. CONCLUSIONS: Pregnancy induced hypertension immensely affected placenta which may be responsible for wore postnatal outcomes. This study is of particular importance for Pathologists, Embryologists and Gynaecologists.
Psoas minor (PM) muscle belongs to the category of vestigial muscles. It is large in size in all those quadrupeds that brachiate and leap or run at very fast speed. None of these functions being required in bipedal, plantigrade man the muscle has receded during evolution; hence it is present only in 40-60% population. Apart from racial variations, a large number of morphological variations of this muscle have been described in the literature. The present study has been conducted in 20 cadavers. Psoas minor muscle was present bilaterally in 35% cases and unilaterally in 5% cases; overall incidence being 40%. Average length of fleshy belly was 7.85 cm that of tendon was 13.13 cm. Average maximum width of fleshy belly was 1.93 cm, and that of the tendon was 0.77cm.
Radial nerve is usually a branch of the posterior cord of the brachial plexus. It innervates triceps, anconeous, brachialis, brachioradialis, extensor carpi radialis longus muscles and gives the posterior cutaneous nerve of the arm, lower lateral cutaneous nerve of arm, posterior cutaneous nerve of forearm; without exhibiting any communication with the medial cutaneous nerve of forearm or any other nerve. We report communication between the radial nerve and medial cutaneous nerve of forearm on the left side in a 58-year-old male cadaver. The right sided structures were found to be normal. Neurosurgeons should keep such variations in mind while performing the surgeries of axilla and upper arm.
Anterior cruciate ligament injury is commonly seen in sports related trauma. Complete tear requires surgical reconstruction. During postoperative rehabilitation, because of arthrogenic muscle inhibition (AMI), the quadriceps muscle remains inactive and has reduced contraction. Various strategies were aimed at treating this AMI and/or improve quadriceps strength such as open chain (OKC) and closed chain kinetic (CKC) exercises, blood flow resistance training (BFRT), cryotherapy, and transcutaneous nerve stimulation (TENS). Of all these, CKC was better than OKC in improving the range of movements, weight bearing exercises provided quicker return to physical activity. Cryotherapy was found to be an effective way to counter AMI and improve knee function and reduce the pain. The BFRT and TENS were found to be ineffective. Single legged hop test at six months postoperatively was found to be reliable predictor of the quadriceps function at one year. Electromechanical dynamometry is the gold standard machine to assess the knee extension and provide exercise, handheld dynamometry is easy to use. Leg press, leg extension machine are other machines used to provide exercises.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
