Corpus Callosum Diffusion Restriction in Neonatal Congenital Myotonic Dystrophy

Hiroyuki Ikeda, Yuki Inami, Yasushi Noguchi, Katsunori Fujii

Congenital myotonic dystrophy (CDM) is the most severe form of myotonic dystrophy type 1 (DM1), typically presenting in the neonatal period with hypotonia, respiratory distress, and feeding difficulties. Neuroimaging findings in neonates with CDM are rarely described. We present a genetically confirmed …

Usefulness of Somatosensory Evoked Potentials in Non-traumatic Spinal Cord Injury in the Absence of MRI Abnormalities: A Case Report

Yuki Inami, Katsunori Fujii

Non-traumatic spinal cord injury (ntSCI) in childhood rarely occurs during activities of daily living, such as stretching, surfing, or physical education classes. Its pathogenesis remains to be elucidated; however, excessive spinal extension has been suggested as the causative etiology. A previously healthy …

Prolonged head banging improved by adenoidectomy in a 6-year-old girl

Yuki Inami, Katsunori Fujii, Hiroko Tada

Background Head banging is a sleep-related rhythmic movement disorder in children, characterized by sudden banging of the head on the crib headboard or side railing during sleep. It usually improves before 4 years of age, but may persist into adolescence owing to …

Examination of Physical Fitness and Bone Mineral Density Based on Differences in Morphological Quality in Adolescent Girls

Yuki Takeyama, Katsunori Fujii

BMI is convenient because it is easily used to determine the level of obesity and slimness, but because the degree of fat mass accumulation differs in relation to body type, the physical strength and athletic ability of obese and slim individuals may …

Establishment of Physical Strength Evaluation Findings on Slim School Age Children: Analysis of Fifth Grade Primary School Students

Yuki Takeyama, Katsunori Fujii

Hypotheses on physical strength and athletic ability in people with slim body types have yet to be clearly proven. Certainly, several studies have been reported, but none have gone beyond the realm of speculation. This is due to the fact that an …

Proposal of WIM-LMS Curves for Standardized Curves of Physical Growth in Young Children

Kentaro Hayakawa, Katsunori Fujii, Nozomi Tanaka

The standardized curves of physical development in infancy should reflect the reality of developmental phenomena. Especially curves using percentile values, it is important to verify developmental changes by analyzing growth rate curves. Therefore, a wavelet interpolation model that can derive speed was …

Relational Composition between Periodic Fluctuation and Seasonal Variation in Height Growth

Nozomi Tanaka, Katsunori Fujii

The influence of seasonal variations in height growth has been frequently discussed previously. In recent years, however, Fujii[1] has hypothesized periodic fluctuations, accordingly the variation is not from the environmental factor of season; rather, height growth is achieved with periodic variations due …

Examination of Universal Racial Differences in Biological Parameters: Analysis Based on Wavelet Interpolation Model

Katsunori Fujii

It is known that the human body is becoming larger, even when viewed historically. Since around 1900 a remarkable trend has been seen globally. Genetically, this phenomenon has been hypothesized to be a mini-evolutionary phenomenon related to epigenetics, but that has not …

Proposal for Growth and Development Evaluation Chart of Physical Abilities in Preschool Children-Analysis based on wavelet interpolation model-

Katsunori Fujii, Nozomi Tanaka, T. Ishigaki, Toshiro Sakai et autres

Growth and development evaluations of physical abilities (physique, motor ability) in preschool children are generally done with uniform evaluation charts of evaluation ranges based on cross-sectional data. In recent years, objective evaluation methods with least squares approximation polynomials have also been established. …

Validity for General Type Model Based on Fujimmon Growth Curve

Katsunori Fujii

Fujimmon's growth curve was proposed by Fujii[1], but unlike Scammon's growth curve, three growth patterns were set. Moreover, Scammon's growth curve was drawn freehand, but Fujimmon's growth curve is drawn by a wavelet interpolation model. The growth curve for each type is …

Verification of Changes in Body Proportions in Humans

Katsunori Fujii

So far, the growth curves proposed by Scammon (1930) have been often used to advantage when explaining the changes in human proportions. With regard to these explanations, the growth was understandable if seen as the relative growth of the general growth pattern …

Applicability of Bergmann’s Rule and Racial Stature difference

Katsunori Fujii, Jun-Dong Kim

Bergmann’s rule(Bergmann, 1847)states that homeothermic animals that live in colder regions such as Northern Europe have larger body sizes with smaller surface area in proportion to body weight in order to minimize heat dissipation. Conversely, in tropical regions body surface area is …
