1.Clinical Experiences of the Hip Arthroscopy
The Journal of the Korean Orthopaedic Association 1995;30(4):933-938
Hip arthroscopy is technically demanding procedure and it is difficult to inspect the entire joint space. But with the development of instruments and the accumulation of results of research, the indications of hip arthroscopy are expanding. The operative arthroscopy of 18 joints was performed during the past four years. We used the supine position on the fracture table and anterolateral and lateral portals. Removal of traumatic loose bodies and synovial chondromatosis, lavage of pyogenic arthritis are excellent indications for the arthroscopic surgery of the hip joint. The results of the partial synovectomy and debridement for rheumatoid arthritis and other arthritis are satisfactory. The hip arthroscopy is beneficial to the diagnosis and treatment for the unexplained hip pain.

Asian Spine Journal 2020;14(5):710-720
Chronic compression or ischemia of the spinal cord in the cervical spine causes a clinical syndrome known as cervical myelopathy. Recently, a new term “degenerative cervical myelopathy (DCM)” was introduced. DCM encompasses spondylosis, intervertebral disk herniation, facet arthrosis, ligamentous hypertrophy, calcification, and ossification. The pathophysiology of DCM includes structural and functional abnormalities of the spinal cord caused by static and dynamic factors. In nonoperative patients, cervical myelopathy has a poor prognosis. Surgical treatments, such as anterior or posterior decompression accompanying arthrodesis, arthroplasty, or laminoplasty, should be considered for patients with chronic progressive cervical myelopathy. Surgical decompression can prevent the progression of myelopathy and improve the neurologic status, functional outcomes, and quality of life, irrespective of differences in medical systems and sociocultural determinants of health. The anterior surgical approach to the cervical spine has the advantage of removing or floating the intervertebral disk, osteophytes, and ossification of the posterior longitudinal ligament that compress the spinal cord directly. The posterior surgical approach to the cervical spine is mainly used for multisegment spinal cord compression in patients with cervical lordosis. In this review article, we addressed the pathophysiology, clinical manifestations, differential diagnosis, and treatment options for DCM.

BACKGROUND: Neer type II distal clavicle fractures have the drawback of coracoclavicular instability and insufficient distal bony fragment, thereby making it difficult to achieve adequate fixation. Although various surgical treatments have been described for Neer type II fracture, the optimal treatment remains controversial. This study reports the clinical results and usefulness of anatomical locking plate with additional K-wire fixation. METHODS: A totally of 21 patients with type II distal clavicle fracture were included in the study. The surgical procedure reduced the fracture temporarily; it included insertion of one or two K-wire from the lateral margin of the distal fragment to the proximal fragment through the fracture site, followed by application and fixation of the locking plate. The bony union and migration of K-wire was evaluated in the follow-up radiography. The coracoclavicular distance and acromioclavicular joint arthrosis were assessed at the final follow-up. The Constant Score (CS) and Korean Shoulder Score (KSS) were evaluated for clinical scoring. RESULTS: Bone union was achieved in all cases. At the final follow-up, coracoclavicular distance of the injured shoulder was increased, as compared to the intact shoulder (p=0.002), with no accompanying clinical symptoms. No K-wire migration was observed. At the final follow-up, K-wire irritation was observed in two cases and acromioclavicular arthrosis in one case, with no other adverse effects. Pain visual analogue scale, CS, and KSS were improved in all cases. CONCLUSIONS: The method of anatomical locking plate with additional K-wire fixation could be useful in achieving beneficial clinical results.

4.New Retear Pattern after Rotator Cuff Repair at Previous Intact Portion of Rotator Cuff.

Retear patterns after arthroscopic rotator cuff repair are classified into two patterns according to retear location. Type 1 is when the retear pattern occurs directly on the tendon at the bone repair site using the suture anchor repair method. Type 2 is when the retear pattern occurs at the musculocutaneous junction with a healed footprint in patients who undergo the suture bridge method. Here, the authors report another retear pattern, which was identified as a type 2 retear on magnetic resonance imaging in patients who had undergone arthroscopic rotator cuff repair by the suture-bridge technique. This pattern was different from the type 2 retear and occurred at the portion of the cuff away from the healed rotator cuff under the view of the arthroscope.

Folliculosebaceous cystic hamartoma is a rare, benign condition. The histological criteria of folliculosebaceous cystic hamartoma have been well established by Kimura et al. We report two cases of folliculosebaceous cystic hamartoma which showed typical histological findings. As far as we know, it has not yet been reported in Korean dermatological literature. The first case is a 23-year-old man who had a pedunculated nodule on the scalp. The second one is a 46-year-old man who had a bean sized pedunculated nodule on the left cheek.

To evaluate the typical appearance and the influence in the image interpretation of the metallic artifact which is known as one of the patient-related field artifacts, we analysed the magnetic resonance (MR) images of 40 patients (the total number of metallic materials were 45) acquired at MR 1.5T unit. All patients were screened for the presence of metal. The metallic implants were surgical wires and clips, orthopedic devices, and the other miscellaneous materials. The artifacts produced by metallic objects can be seen on MRI as the focal loss of signal and/or the local distortion of the image. Regardless of their ferromagnetic properties, metallic implants created regional artifacts in their images. Ferromagnetic materials, such as a lead fragment, showed severe artifacts and nonferromagnetic metals showed mild to moderate artifacts. The conspicuity of artifact was related tot he composition, mass, shape, orientation, and the location of the metallic objects in the body. Under high magnetic field strength, there were no significant differences between the various pulse sequences. Artifacts are particularly prominent on gradient-echo images. Our findings indicate that MR imaging of patients with standard nonferromagnetic metallic materials can be successfully performed and usefully interpretated.

Toxoplasma gondii, an intracellular coccidian protozoan, is the causative agent of toxoplasmosis, a widespread infection affecting various birds and mammals including humans. In immunocompetent hosts, the infection is usually asymptomatic and benign. Toxoplasmosis is either congenital or acquired. In general prenatal therapy of congenital toxoplasmosis is beneficial in reducing the ncy of infant infection. Therapies are based primarily on spiramycin because of the relative lack of toxicity and high concentration achieved in the placenta. Clindamycin is the standard drug for chemoprophylaxis in newborn infants, and is directed at preventing the occurrence of retinochoroiditis as a late sequel to congenital infection. The standard treatment for acquired toxoplasmosis in both immunocompetent and immunodeficient patients is the synergistic combination of pyrimethamine and sulphonamides. Toxoplasmic encephalitis is tbe most common manifestation of acquired toxoplasmosis in immunocompromised patients and if not treated is fatal. However, because of toxicity, the therapeutic efficacy of pyrimethamine sulphonamide combinations may be seriously limited in immunodeficient patients. We have experienced a case of toxoplasmosis during the workup of habitual aborter. So we report this case with a brief review of literatures.
