We did not detect patients with sarcopenia on the basis of ALMI, T-ALMI. After revision of these criteria for fat mass, almost all patients started to meet the criteria of sarcopenia (98.0%).
To explore whether quadratic model will better estimate the relationship between aging and thigh tissue composition in a cohort that range in age from young to older adults.

51 healthy subjects participated in this investigation. All subjects underwent CT imaging for the thigh. Cross-sectional area of the fat and muscular tissues in the thigh were quantified. Hierarchical regression models were created. Age was entered first into the models to estimate its linear relationship with the thigh tissues. Then the squared value of the age variable was entered second to identify whether a quadratic model would better estimate the relationship between the variables.

The linear model was significant for thigh muscular tissue. Quadratic models were able to account for additional significant prediction of the cross-sectional area of thigh tissues. Muscular area decreased with aging until 60 years after that it didn't change. Fat areas increased with aging until 45-50 years and then it decreased.

The cross-sectional area of different thigh tissues exhibit a curvilinear pattern with aging. Muscular tissue area may not change after 60 years; this could be explained by the reduction in fat that may infiltrate inside the muscles and offset the muscular reduction.

To explore complex correlations between obesity (OB) and osteoporosis (OP) after adjustment of static mechanical loading from weight and fat free mass (FFM).

A total of 3749 Chinese aged ≥65 years were selected from our ongoing cohort study. OB indices and bone mineral density (BMD) were measured for each subject. Linear regression analyses were performed to explore the correlations between OB indices and OP under three adjustment models (unadjusted, adjusted with weight and adjusted with FFM).

Under no adjustment, three general obesity indices (body mass index BMI, fat mass FM, and percentage FM PFM) were positively associated with BMD at three skeletal sites (P<0.001) in the regression analyses. However, after the adjustment with weight, these associations were mostly significant but reverse i.e., negatively in direction. After adjustment with FFM, the three indices were still positively and significantly (P<0.001) associated with BMD but regression coefficients were smaller compared to the unadjusted associations. Similar associations were observed for central adiposity and lower limb adiposity indices.

The combined relation of OB to OP due to the physiological factors secreted from adipose tissues and the static mechanical loading from FM is positive in direction.

Children with Duchene muscular dystrophy have weak muscles, which may impair postural adjustments. These postural adjustments are required for gait and dynamic balance during the daily living activities. The aim was to compare between the effect of bicycle ergometer versus treadmill on functional walking capacity and balance in children with Duchenne muscular dystrophy.

Thirty boys aged from 6 to 10 years old diagnosed as Duchene muscular dystrophy participated in this study. Children were assigned randomly into two groups (A&B). Children in group (A) underwent a designed program of physical therapy plus aerobic exercise training in form of bicycle ergometer while, group (B) received the same program as group (A) and aerobic exercise training by treadmill for one hour, at three times a week for three successive months. Functional walking capacity and balance were assessed before and after treatment by using the 6-minute walk test and Biodex balance system equipment respectively.

The post treatment results revealed significant difference in all measured variables (P<0.05) as compared with its pre-treatment results. Post-treatment values indicated that there was a significant difference in all measured variables in favor of group B.

treadmill training as an aerobic exercise can improve walking capacity and balance more effectively than bicycle ergometer in children with Duchenne muscular dystrophy.

Obesity is a significant global health concern that involves motor impairment, including deficits in gait and balance. A simple tool would be useful to capture gait and balance impairment in obesity. We assessed whether the Functional Gait Assessment (FGA) captures impairment in individuals with obese BMI (≥30 kg/m
) and whether impairment was related to spatiotemporal gait parameters.

Fourteen individuals with obese BMI and twenty individuals of normal weight underwent the FGA. Spatiotemporal gait parameters were collected while participants walked on a pressure sensitive walkway under five conditions pre-baseline (flat ground walking), crossing small, medium, and high obstacles, and final-baseline (flat ground walking).

Individuals with obesity had lower scores on the FGA (p≤0.001) and showed less efficient spatiotemporal gait parameters than healthy controls, particularly when crossing over obstacles (all ps≤0.05). For participants with obesity, lower FGA scores were associated with decreased gait velocity, but only during obstacle crossing (p≤0.05).

The FGA may be a useful tool to capture gait impairment in populations with obesity. Obstacles may help reveal meaningful gait impairments. To our knowledge, this is the first study to examine the FGA in individuals with obesity, and represents a proof-of-concept that motivates further validation studies.

This case report describes a variant in which the extended fibers of the mentalis crossed the midline and indicates the relationship of these fibers to the surrounding structures. Some of the deepest fibers of the mentalis descended inferomedially and crossed transversely just below the chin prominence to attach to the periosteum of the mandible on the contralateral side. The variation presented in this study shed light on the interactions of the mentalis with the surrounding muscles.A variety of shapes has been reported for the roots and root canals of maxillary first premolars. The purposes of the present study were to determine branching and shapes of the roots of maxillary first premolars, as well as age-related changes using slice images obtained with cone-beam computed tomography (CBCT) for dental use. CBCT-reconstructed images of 125 cases that included maxillary first premolars were used as subjects. Slice images at the cervical one-third, center, and apical one-third positions of the root were prepared. Root branching and number of root canals was determined at each measurement position in the images. The subjects were divided into three groups younger than 30 years, 30 to 50 years, and over 50 years. The root canal morphology was compared among these age groups. Single-rooted premolars were the most frequent. As for number of root canals, a single-canal premolar was observed at the position of the cervical one-third in 33.6%, at the center in 35.2%, and at the apical one-third in 56.0%. Thereafter the subjects were divided into groups by age, namely, younger than 30 years, 30 to 50 years, and over 50 years old, and it was revealed that the ratio of the two-canal type increased with age. In regard to tooth morphology, it was confirmed that the two-canal type shows more frequent occurrence with aging in maxillary first premolar. Based on our findings, we consider that CBCT can be useful for determining the root canal morphology with complicated shapes.Schwannomas are rare benign tumors that develop in Schwann cells lining peripheral nerves. Schwannomas of the brachial plexus are especially rare, accounting for 5% of all cases. Although several treatments can be considered, the exact method of treatment is unclear owing to the scarcity and sporadic occurrence of schwannomas. Tumor resection is performed in most cases, and nerve damage is inevitable in cases of neuroinvasive schwannoma. In this case series, we present our successful use of transposition of cable-grafted nerves for the treatment of schwannomas. We performed cable-grafted nerve interposition in addition to tumor resection, leading to increased recovery of nerve damage. To relieve postoperative symptoms and minimize sequelae, precise surgical tumor resection followed by nerve interposition using a cable-grafted nerve may be recommended.The clinical significance of ground-glass nodules (GGNs) has been investigated in extensive clinical research for many years. The natural history of GGNs is known to be closely related to their size, proportion of solid components, and size progression over time. Based on these data, several guidelines for GGN management have been published worldwide. The indications for nonsurgical biopsy or surgical resection of GGNs are as follows pure GGNs between 5 and 10 mm in size if they increase in size or show development of a solid component at follow-up, pure GGNs >10-15 mm that remain stable but persistent, part-solid nodules >8 mm persisting at follow-up, or part-solid nodules with a solid component >6 mm at follow-up. Newly updated data considering geographical or racial factors and recent developments in surgical techniques may improve the surgical indications for GGNs in the near future.Migraine and tension-type headache are common in children and adolescents, but several other headache disorders may pose a great challenge in diagnosis and management to families and attending clinicians. In this review, we highlight several of these disorders, which need appropriate assessment to make the right diagnosis and appropriate investigations where necessary. Timely recognition and implementation of appropriate management strategies can improve the health of children with some disorders, and is vital in achieving improvement in the quality of life.
To assess the adverse effects of propranolol therapy in infantile hemangioma.

An ambispective study was conducted from August 2011 to December 2019. In retrospective arm all children managed for infantile hemangioma with propranolol were included and case records were assessed for adverse reactions. In prospective arm the adverse reactions were identified on the basis of predefined criteria.

A total of 514 patients (358 retrospective records) were included. A majority, 378 (73.5%) patients had an excellent response, 75 (14.5%) had partial response and 61 (11.8 %) had no response. A total of 82 (15.9%) patients experienced at least one adverse effect. Diarrhea with weight loss (27, 32.9%) and irritability with decreased sleep (21, 25.6%) were the most common adverse effects. The adverse effects in 22 (4.2%) cases lead to the discontinuation of propranolol. 4-Phenylbutyric acid concentration Younger age, low body weight and early onset were risk factors for development of severe adverse reactions.

Young children with low body weight were at higher risk for adverse effects of propranolol.
