  • Forearm fractures are common injuries in childhood. Median nerve entrapment is a rare complication of forearm fractures, but several cases have been reported in the literature. This case report discusses the diagnosis and management of median nerve entrapment in a 13-year-old male who presented acutely with a both-bone forearm fracture and numbness in the median nerve distribution. Following the delayed diagnosis, surgical exploration revealed complete nerve entrapment and a nerve graft was performed.

  • Ellagic acid (EA) is a naturally occurring polyphenolic compound in vegetables, nuts, and fruits such as berries. EA has antioxidant, anticancer, anti-allergy, and anti-inflammatory activities. The objectives of this research were to investigate the physicochemical properties of nanoparticles before and after nano-encapsulation of EA in dairy protein and to develop a functional (anti-inflammatory) dairy protein-based beverage containing EA. A particle size analyzer was used to determine the physicochemical and morphological properties. High performance liquid chromatography was used to evaluate the entrapment efficiency of EA. The nanoparticles containing EA were 100 to 200 nm in diameter. The determined poly dispersity index value of 0.3 to 0.4 indicated that the nanoparticles were uniformly distributed with similar size. Zeta-potential values were also similar between the control groups. The entrapment efficiency of EA was nearly 90%. The results indicate the potential for development of nanoparticles containing EA beverage products with anti-inflammatory activity.

  • A drop impact on the liquid film/pool generates several phenomena such as the drop floating, bouncing, formation of vortex ring, jetting, bubble entrapment and splashing. These phenomena depend on the impact velocity, the drop size, the drop properties and the liquid film/pool thickness. These parameters can be summarized by four main dimensionless parameters; Weber number, Ohnesorge number, Froude number and non-dimensional film/pool thickness. In the present study, the phenomena of the splashing and bubble entrapment due to the drop impact on the liquid film/pool were numerically investigated by using a Level Set method for the sharp interface tracking of two distinct phases. After the drop impact, the splashing phenomena with the crown formation and spreading were predicted. Under the specific conditions, the bubble entrapment at the base of the collapsing cavity due to the drop impact was also observed. The numerical results were compared to the available experimental data showing good agreements.

  • Anterior cutaneous nerve entrapment syndrome (ACNES) is one the most common cause of chronic abdominal wall pain. The syndrome is mostly misdiagnosed, treated wrongly and inadequately. If diagnosed correctly by history, examination and a positive carnett test, the suffering of the patient can be relieved by addressing the cause i.e. local anaesthetic with steroid injection at the entrapment site. Conventionally, the injection is done by landmark technique. In this report, we have described 2 patients who were diagnosed with ACNES who were offered ultrasound guided transverses abdominis plane (TAP) injection who got significant pain relief for a long duration of time.

  • A cell-entrapment technique using compressed air was applied to Bifidobacterium longum KCTC 3128 for the improvement of bifidobacteria viability. The main cell-entrapment matrix used was alginate, and viability improvement of the B. longum entrapped in alginate lattices was monitored along with the effects of other additional biopolymers. A prerequisite for acquiring consistent results was the uniformity of bead size and cell distribution which was achieved by using compressed air and mixing the cell suspension with sterilized alginate powder, respectively. The viability losses of the B. longum entrapped in alginate beads in the presence of three different substances logarithmically increased in relation to the reaction time, and proportionately decreased with an increased alginate concentration and bead diameter. The strongest improvement in B. longum viability was exhibited with a bead containing 3% alginate and 0.15% xanthan gum.

  • The purpose of this study was examine the mediating effects of psychological flexibility and entrapment on the relationship between college students's life stress and adjustment to college life. A sample of 142 college students at a university located in Jeonju city completed self-report measures of life stress, psychological flexibility, entrapment and adjustment to college life. In order to examine the mediating effect, The collected data from college students were analyzed by the procedures prosposed by Baron and Kenny. Psychological flexibility and entrapment partially mediated the relationship between life stress and adjustment to college life, indicating that life stress directly affect adjustment to college life and indirectly affect adjustment to college life through psychological flexibility and entrapment. Finally, limitations of the results of this study and therapeutic interventions to prevent maladjustment by college students were discussed.

  • Purpose: Median nerve entrapment syndrome within carpal tunnel is usually called carpal tunnel syndrome and it is the most common form of peripheral nerve entrapment syndrome. Many factors such as diabetes mellitus, hypothyroidism, hormonal replacement theraphy, corticosteroid use, rhematoid arthritis and wrist fractures may cause carpal tunnel syndrome. To the best of our knowledge, this is the first case report of median nerve entrapment syndrome due to adhesion of laceration wound after suicidal attempt. Methods: A 28-year-old woman presented with a sensory change and thenar hypotrophy on her left hand. On her history, she attempted suicide by slashing her wrist. Initial electromyography (EMG) showed that the nerve conduction velocities of median nerve was delayed. Therefore, we performed surgical procedures. When exploration, Fibrous scar tissue observed around the median nerve but nerve had not been injured. Transcarpal ligament was completely released and adjacent fibrous tissue was removed to decompress the median nerve. Results: The postoperative course was uneventful until the first year. Opposition difficulty and thenar hypotrophy were improved progressively after the surgery. Sensory abnormality was slowly improved over one year. Conclusion: We report a case of median nerve entrapment syndrome that was caused by adhesion of laceration wound after suicidal attempt. This is an unusual cause of median nerve entrapment syndrome, the symptoms were relieved after transcarpal ligament release and fibrous scar tissue removal.

  • Purpose: The purpose of this study is to describe the characteristic clinical findings and treatment of suprascapular nerve entrapment by ganglion and to evaluate its results. Materials and Methods: Seven paitents with suprascapular nerve entrapment were evaluated on an average 13 months(range, six months to three years two months) after surgical excision and decompression. There were six males and one female. The mean age at operation was 31 years(range, 23 to 40 years), Suprascapular nerve entrapment were caused by compression of ganglion cyst in suprascapular notch or spinoglenoid notch in all cases. All patients complained of pain located over posterolateral area of the shoulder. Two patients had atrophy of both the supraspinatus and infraspinatus muscles, In four patients, only the infraspinatus muscle was involved. Muscle strength on both forward flexion and external rotation was decreased in two patients. In four patients, only external rotation was decreased. All patients underwent open excision of ganglion cyst and decompression. Results: The most dramatic effect of operation was prompt disappearance of pain in all patients. The average visual analog scale had improved from 7.2 to 0.6 point at the latest follow-up evaluation. An atrophy of the supraspinatus or infraspinatus muscle partially disappeared in four of six patients and muscle strength of forward flexion or abduction improved in all of six patients. The overall result was excellent for five patients and good for two. Conclusion: Surpascapular nerve entrapment by ganglionic cyst had clinically unique symptoms and signs on physical examination. Surgical excision is effective for symptomatic and functional outcomes. We believe that early intervention can be one of treatment modality before an irreversible damage occurs if the ganglion is large enough to compress suprascapular nerve, and to develop severe pain and muscular atrophy.
