Tracheo-innominate artery fistula (TIF) is a life-threatening complication of tracheostomy that manifests with acute and massive bleeding. We present a patient who deveoloped a TIF and underwent a division of the fistula, interrupting the innominate artery. Successful management of a patient with TIF requires the rapid institution of specific resuscitative and operative measures. The patient arrived at the emergency room with acute massive tracheal bleeding, respiratory difficulty, decreased consciousness and ensuing cardiac arrest. After the tracheal cuff was fully inflated, cardiopulmonary resuscitation was started. Fortunately, the bleeding was stopped and heart rate and blood pressure were normalized. Before performing the cerebral angiography, the patient was intubated orally for rebleeding. The patient was admitted to the intensive care unit and stayed for 29 days due to weaning failure from the ventilator. After repair of tracheal stenosis, a permanent tracheostomy was instituted. The patient had no respiratory difficulty or massive tracheal bleeding during the 2 months after discharge except one episode of minor bleeding.

The authors conducted an in-Vivo experimental study using sciatic nerve of 200-300 grammed rats to verify clinical applicability of Silicone cuffing method, by which scar adhesion of repaired nerve in crushed limb is assumed hopefully to be reduced. The following observations were obtainable. 1. Nerve conduction velocity was noted faster in Silicone cuff group than in control group significantly after 6 weeks postoperatively. 2. Adhesion of repaired nerve with surrounding scar tissue was far less present in Silicone cuff group than in control group when observed grossly. 3. The amount of scar formation and axonal degeneration were noted reduced remarkably in Silicone cuff group than in control group after 3 weeks postoperatively. 4. The intraneural vascularity was noted reduced either in Silicone cuff group and in control group, but definitely less reduced in the former than in the latter. Clinical relevance: Above results may be taken as an experimental basis supporting clinical applicability of Silicone cuff wrapping method for neurorraphy in crushed limb.

PURPOSE: To analyze the clinical outcome for primary ring flexor digitorum superficialis transfer with open carpal tunnel release in extreme carpal tunnel syndrome. METHODS: Ring flexor digitorum superficialis transfer with open release of the transverse carpal ligament was performed on 23 patients who were diagnosed with extreme carpal tunnel syndrome between September 2008 and August 2013. All patients had visibly severe atrophies, with no sign of compound muscle action potential (CMAP) of abductor pollicis brevis from electromyography. They wanted simultaneous reconstruction of the function of the hand as well as recovery of the numbness. We evaluated the clinical results using key-pinch, hand grip abilities, disability of the arm, shoulder and hand (DASH) scores, Kapandji scores. RESULTS: Key-pinch and hand grip abilities had no significant difference after the surgery compared with before, but DASH scores were significantly different, averaging 18.6 after, compared with 39.8 before surgery. And Kapandji scores increased significantly from 4.8 before, to 9.3 after the surgery. Numbness and pain in hands were also markedly improved with a different score on VAS each. CONCLUSION: Primary ring flexor digitorum superficialis opponensplasty with open carpal tunnel release is a very practical and useful way of treating extreme carpal tunnel syndrome in thenar weakness.

Recently, percutaneous epidural neuroplasty has become widely used to treat radicular pain caused by spinal stenosis or a herniated intervertebral disc. A 19-year-old female patient suffering from left radicular pain caused by an L4-L5 intervertebral disc herniation underwent percutaneous epidural neuroplasty of the left L5 nerve root using a Racz catheter. After the procedure, the patient complained of acute motor weakness in the right lower leg, on the opposite site to where the neuroplasty was conducted. Emergency surgery was performed, and swelling of the right L5 nerve root was discovered. The patient recovered her motor and sensory functions immediately after the surgery. Theoretically, the injection of a large volume of fluid in a patient with severe spinal stenosis during epidural neuroplasty can increase the pressure on the opposite side of the epidural space, which may cause injury of the opposite nerve by barotrauma from a closed compartment. Practitioners should be aware of this potential complication.

Mucosa-associated lymphoid tissue (MALT) lymphoma is an uncommon form of non-Hodgkin lymphoma involving the mucosa-associated lymphoid tissue. Most commonly affected organ is the stomach. But, it could affect almost every organ in the whole body. If they have suspicious lesion, excision biopsy could be made. For staging, blood test including blood smear, abdomen and chest tomography or scan will be checked. Also, bone marrow test can be done if it is needed. The patient had visited the clinic for palpable mass on right lower eyelid. With excisional biopsy, it was diagnosed as lymphoid hyperplasia on pathologic test. But 2 years later, the patient came with recurrent symptom for our department with worry. At that time, we recommended excisional soft tissue biopsy under general anesthesia. Unfortunately, it was revealed MALT lymphoma on pathologic finding. It turned out to be stage 3 in Ann Arbor staging system without B symptoms. Hematologic consultation was made and she was treated with adjuvant chemotherapy for eight cycles to complete remission. We report a case of MALT lymphoma on subcutaneous tissue at right lower eyelid previously diagnosed as lymphoid hyperplasia.

Malignant pilomatricoma (pilomatrical carcinoma) is a rare, locally occurring malignant tumor with a high rate of recurrence in the case of incomplete excision. This tumor has two characteristics. First, recurrences of pilomatrical carcinoma are common; second, distant metastasis is rare, but if it occurs, it is very fatal. It has characteristic features of high mitotic counts, cellular atypia, and local invasion. Although fine needle aspiration and excisional biopsy could help to confirm this tumor diagnosis, pathologic findings are critical. Pilomatricomas have some characteristic features in histological aspect, such as epithelial islands of basaloid cells and shadow cells or ghost cell. Also, various types of immunohistochemical staining are used to confirm the diagnosis. Despite the lack of clear surgical criteria, treatment is a wide local excision with histologically clear resection margins with or without adjuvant radiotherapy.

Malignant peripheral nerve sheath tumors (MPNSTs) are rare and aggressive soft tissue sarcomas of neural origin. Approximately 50% of MPNSTs are associated with neurofibromatosis type 1 (NF1), a neurocutaneous condition characterized by skin discoloration. MPNSTs occur in approximately 4% of patients with NF1. Malignancy should be suspected when a large mass consistent with a neurofibroma is observed with heterogeneity on a radiologic examination. In our case, immunohistochemistry revealed the presence of antigens for both the tumor protein p53 and the proliferation marker Ki-67 (MKI67). In particular, MKI67 positivity helped to differentiate MPNST from neurofibroma. Complete surgical resection is the standard treatment. After surgery, radiation therapy is typically administered to the resection area to reduce the likelihood of recurrence. Following treatment, patients should undergo regular clinical follow-up using a combination of magnetic resonance imaging, computed tomography, and bone scanning for several years to monitor them for possible metastasis.

Objectives:
This study aimed to identify the effectiveness of treatment programs for children with reading (RD) or mathematics disorders (MD). Structured treatment programs were developed to improve phonological awareness and number sense among children and adolescents with RD or MD, respectively, and the effectiveness of the learning disorder treatment programs were evaluated.
Methods:
We used standardized, objective diagnostic, and evaluation tools not only to recruit participants with RD, MD, or comorbid attention deficit and hyperactivity disorder, but also to assess the effectiveness of the treatments regarding both improved core neurocognitive deficits of RD or MD and academic achievement. Forty children with RD or MD received one-on-one treatments from therapists.
Results:
In the RD group, treatment effects were observed in all subtests. In the word and paragraph reading tests, the accuracy rates and fluency improved. The results of the phonological working memory test, word–sound correspondence test, and rapid automatic naming tests also improved. In the MD group, the accuracy rate and fluency on the arithmetic test improved. An increase in the accuracy rate in the size and distance comparison tests and a decrease in the error rate in the estimation test were also observed. However, there were no improvements in reaction time in these subtests.
Conclusion
Learning disorder treatment programs that focus on improving phonological awareness or number sense in children with RD or MD improved achievement, phonological awareness, and number sense.
