Pupillary Reactivity

✓ A series of 8814 head-injured patients admitted to 41 hospitals in three separate metropolitan areas were prospectively studied. Of these, 1906 patients (21.6%) were 14 years of age or less. This “pediatric population” was compared to the remaining “adult population” for mechanism of injury, admission Glasgow Coma Scale score, motor score, blood pressure, pupillary reactivity, the presence of associated injuries, and the presence of subdural or epidural hematoma. The relationship of each of these factors was then correlated with posttraumatic mortality. Except for patients found to have subdural hematoma and those who were profoundly hypotensive, the pediatric patients exhibited a significantly lower mortality rate compared to the adults, thus confirming this generally held view. This study indicates that age itself, even within the pediatric age range, is a major independent factor affecting the mortality rate in head-injured patients.

Background: Avascular necrosis (AVN) or osteonecrosis is the death of bone tissues due to decreased blood flow of femoral head, it is a major orthopaedic disease with many risk factors including the chronic alcohol and tobacco consumption.  Aims and objectives: To study the relationship of alcohol and tobacco with AVN of femoral head in adult population. Materials and Methods: This study included 72 patients of AVN of femoral head (ONFH) who attending our hospital between Sept 2018 to Sept 2020. History of alcoholism and tobacco consumption, detailed information of the amount and duration of smoking and alcohol intake was recorded. Results: Majority of the AVN patients were working age groups males (72%) and 28% were females. Out of 72 patient 55% had history of alcohol consumption and 60% were smokers which indicates a positive correlation of cellular toxicity with AVN of femoral head. Conclusion: Present study conclude that the alcohol ingestion and tobacco smoking are the major cause of cellular toxicity and AVN of femoral heads.

Immature Fish

During the summers of 1951–53, small body-cavity tags were inserted in 55,547 juvenile (1-year) herring on the lower west coast of Vancouver Island. Fifty of these tags were recoved from the catches of adult fish between 1953–54 and 1956–57. These recoveries indicated homing by sub-district (the region occupied by an adult population) to be 52% after two years at large, and 64% after three years. Comparable data for herring tagged as adults showed 82% and 81% homing respectively. The greater tendency for the immature fish to mix with other adult populations may result from the fact that these fish join adult schools when the latter are considerably dispersed and intermixed on the offshore feeding grounds. Thus, population studies linking the juvenile and adult stages may require the use of a larger basic unit of area than that encompassing the distribution of the adult population. The dimensions of this unit will depend on the local potential for intermixing of adult populations at the time of recruitment.

A longitudinal investigation of changes of signs and symptoms of man dibular dysfunction over four to five years was performed, by means of questionnaires and clinical examination, in 240 children, ages 7, 11, and 15 years at the first examination. The objective of this part of the study was to analyze correlations between some occlusal and other factors, and mandibular dysfunction. Signs and symptoms of mandibular dysfunction increased slightly in both frequency and severity but were judged to be mild in most cases. Several types of occlusal interference were frequently recorded at both examinations. Dental wear increased during the follow-up period, while the results of evaluations of motor activity and psychological traits were relatively constant. There were only a few significant correlations, most of which were weak, between the recorded variables and mandibular dysfunction, and those found were not consistent in all age groups. TMJ sounds were positively correlated with lateral deviation of the mandible between retruded contact and intercuspal position in all age groups. An attempt to analyze the longitudinal relationship of occlusal interference with signs and symptoms of mandibular dysfunction did not reveal any strong correlations. The results are interpreted as supporting the heterogeneous and multifactorial nature of functional disturbances of the masticatory system.

Objectives: To focus on hypothalamic-pituitary-adrenal (HPA) axis activity, especially endogenous hypercortisolemia, to study its role in the maintenance of psychiatric illness, and to entertain the probability that the elderly are vulnerable. Method: Case presentation, clinical and research literature review, and theoretical discussion. Results: Clinical and research evidence overwhelmingly suggest that hypercortisolemia is toxic to the hippocampus. Some research supports the position that it can be a treatable perpetuating factor in a subset of affective disorders and psychoses. Pharmacological treatments to correct hypercortisolemia have been used by endocrinologists. Hypercortisolemic treatment-resistant and nontreatment-resistant psychoses and affective disorders have been successfully treated by a small number of researchers who remain interested in this subject. Data pertaining to geriatric psychoses may be germane but are sparse. Conclusions: It behooves us to research diagnostic methods pertaining to psychoses and affective disorders associated with hypercortisolemic states. Very little research is available, but we must be alert to the possibility that the elderly are more susceptible to cortisol endotoxicosis than the younger adult population. Without accurate diagnosis, we cannot take advantage of existing antiglucocorticoid strategies.

Biologic Factors

The Mesozoic-Cenozoic coral Order Scleractinia has been suggested to have originated or evolved (1) by direct descent from the Paleozoic Order Rugosa or (2) by the development of a skeleton in members of one of the anemone groups that probably have existed throughout Phanerozoic time. In spite of much work on the subject, advocates of the direct descent hypothesis have failed to find convincing evidence of this relationship. Critical points are:(1) Rugosan septal insertion is serial; Scleractinian insertion is cyclic; no intermediate stages have been demonstrated. Apparent intermediates are Scleractinia having bilateral cyclic insertion or teratological Rugosa.(2) There is convincing evidence that the skeletons of many Rugosa were calcitic and none are known to be or to have been aragonitic. In contrast, the skeletons of all living Scleractinia are aragonitic and there is evidence that fossil Scleractinia were aragonitic also. The mineralogic difference is almost certainly due to intrinsic biologic factors.(3) No early Triassic corals of either group are known. This fact is not compelling (by itself) but is important in connection with points 1 and 2, because, given direct descent, both changes took place during this only stage in the history of the two groups in which there are no known corals.

Insight Into

Echinodermata is a phylum of marine invertebrates which has been extant since Cambrian time (c.a. 500 m.y. before the present). Modern examples of echinoderms include sea urchins, sea stars, and sea lilies (crinoids). The endoskeletons of echinoderms are composed of plates or ossicles (Fig. 1) which are with few exceptions, porous, single crystals of high-magnesian calcite. Despite their single crystal nature, fracture surfaces do not exhibit the near-perfect {10.4} cleavage characteristic of inorganic calcite. This paradoxical mix of biogenic and inorganic features has prompted much recent work on echinoderm skeletal crystallography. Furthermore, fossil echinoderm hard parts comprise a volumetrically significant portion of some marine limestones sequences. The ultrastructural and microchemical characterization of modern skeletal material should lend insight into: 1). The nature of the biogenic processes involved, for example, the relationship of Mg heterogeneity to morphological and structural features in modern echinoderm material, and 2). The nature of the diagenetic changes undergone by their ancient, fossilized counterparts. In this study, high resolution TEM (HRTEM), high voltage TEM (HVTEM), and STEM microanalysis are used to characterize tha ultrastructural and microchemical composition of skeletal elements of the modern crinoid Neocrinus blakei.
