Craniovertebral junction (CVJ) tuberculosis is a rare disease, and potentially fatal due to the risk of atlantoaxial dislocation. The disease usually accompanies a retropharyngeal cold abscess, which can cause subsequential otolaryngologic symptoms such asdysphagia, odynophagia, or airway obstruction. Such a patient must be handled with great care to avoid a disaster. The disease is diagnosed with microbiological or other laboratory tests on the pus collected through puncture and aspiration, which will need otolaryngologic skills. For treatment, otolaryngologists play an important role by doing incision and drainage of the retropharyngeal abscess, or by attending the transoral vertebra surgery as partners with spine surgeons who will manage the CVJ lesions and ensure the craniocervical stability.

Intracranial hypotension is characterized by a postural headache which is relieved in a supine position and worsened in a sitting or standing position. Although less commonly reported than postural headache, sixth nerve palsy has also been observed in intracranial hypotension. The epidural blood patch (EBP) has been performed for postdural puncture headache, but little is known about the proper timing of EBP in the treatment of sixth nerve palsy due to intracranial hypotension. This article reports a case of sixth nerve palsy due to spontaneous intracranial hypotension which was treated by EBP 10 days after the onset of palsy.

Pseudoaneurysm of the abdominal wall is a possible but very rare clinical entity. It is a known complication of surgery, trauma, or arterial puncture, but it is rarely spontaneous. Even though it can usually present with a wide range of local symptoms, it can cause referred pain via spinal cord, which is cross-excited with afferent sympathetic nervous system. We report a case of right arm pain which was referred from a small abdominal pseudoaneurysm like a referred pain from gall bladder. This rare entity should be considered in the differential for pain management in case that the pain does not resolve with medication or interventional pain management.

A 46-year-old man presented with a lateral thoracic meningocele associated with cutaneous neurofibromatosis type I and kyphoscoliosis of the thoracic spine upon medical examination. In the majority of such cases, these meningoceles remain asymptomatic, but surgery is indicated when giant or symptomatic cysts are present. The large thoracic meningocele was successfully extirpated through the transthoracic approach in combination with lumbar puncture and cerebrospinal drainage for decompression of the cyst.

The package used to transport radioactive materials, which is called by cask, must be safe under normal and hypothetical accident conditions. These requirements for the cask design must be verified through test or finite element analysis. Since the cost for FE analysis is less than one for test. the verification by FE analysis is mainly used. But due to the complexity of mechanical behaviors. the results depends on how users apply the codes and it can cause severe errors during analysis. In this paper, finite element analysis is carried out for the 9 meters free drop and the puncture condition of the hypothetical accident conditions using LS-DYNA3D and ABAQUS/Explicit. We have investigated the analyzing technique for the free drop impact test of the cask and found several vulnerable cases to errors. The analyzed results were compared with each other. We have suggested a reliable and relatively simple analysis technique for the drop test of spent nuclear fuel casks.

The frequency of a bladder foreign body in the female is lower than in the male, and bladder stones attached to foreign bodies such as non-absorbable suture material are not common. Moreover, vesicovaginal fistulas due to migration or puncture of suture materials into the bladder are rare. In this report, we present a case of bladder stone and vesicovaginal fistula formation in a 29-year-old female patient who had been treated with the McDonald operation for an incompetent internal os of the cervix (IIOC) during pregnancy. The patient was successfully treated by cystoscopic removal of the bladder stone with suture material and conservative treatment for the vesicovaginal fistula.

Most of aortic injuries after blunt chest trauma usually occur at the aortic isthmus and are identified in the emergency department soon after arrival. Delayed aortic injures by fractured posterior ribs, however, are relatively rare and have been reported only a few times. We recently experienced an iatrogenic descending aortic injury sustained as a result of a direct puncture by a sharp rib end after surgical stabilization of rib fractures.

In infants and small children, ultrasound (US) guidance provides ample anatomical information to perform neuraxial blocks. We can measure the distance from the skin to the epidural space in the US image and can refer to it during needle insertion. We may also visualize the needle or a catheter during real-time US-guided epidural catheterization. In cases where direct needle or catheter visualization is difficult, US allows predicting successful puncture and catheterization using surrogate markers, such as dura mater displacement, epidural space widening due to drug injection, or mass movement of the drug within the caudal space. Although many experienced anesthesiologists still prefer to use conventional techniques, prospective randomized controlled trials using US guidance are providing increasing evidence of its advantages. The use of US-guided regional block will gradually become widespread in infants and children.

Central venous catheter (CVC) insertion is commonly used in the operating room and intensive care unit to monitor central venous pressure and secure an intravenous route to deliver medications and nutritional support that cannot be safely infused into peripheral veins. However, CVC insertion may be associated with serious complications such as arterial puncture, hematoma, pneumothorax, hemothorax, catheter infections, and thrombosis. Several methods have been recommended to prevent these complications. Here we report a case of massive hemothorax caused by attempts of CVC insertion into the internal jugular vein and subclavian vein in a patient with multiple trauma. CVC placement should be performed or supervised by an experienced physician to decrease the incidence of CVC-related complications. CVC insertion under ultrasound guidance is recommended.

Combinatorial methods are being used increasingly to develop the next generation of polymers, coatings and adhesive formulations. Allied to this approach, a new genre of measurement and characterization methods are emerging. These characterization techniques are required to handle and take measurements from small samples. This has led to a number of uses for this technology which usefully fall between convention test specimen and micro- or nano-scale test methods. A versatile measurement platform will be presented which can offer useful indentation, puncture, compression, adhesion and scratch resistance data for a wide variety of material types and that continues to develop and evolve in capability.
