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.

OBJECTIVES: There have been several evidences that the central nervous system defect is one of the etiologic factors in schizophrenia and high nailfold plexus visibility can reflect indirectly. These are particularly related to the negative symptoms of schizophrenia. In this study, we examined the relationship between nailfold plexus visibility and various clinical variables in schizophrenia. METHODS: Forty patients(20 males, 20 females) satisfying the DSM-IV criteria for schizophrenia and forty normal controls(20 males, 20 females) were measured for Plexus Visualization Score(PVS) by using capillary microscopic examination. We used Positive and negative Syndrome Scale(PANSS). Uimann-Giovannoni Process-Reactive Questionnaire(PRQ), Phillips Premorbid Adjustment Scale(PAS). Continuous Performance Test, and Backward Masking for psychopathology and clinical variables. RESULTS: There was no significant relationship between schizophrenic subjects and normal controls in PVS. PVS was correlated with PANSS positively except negative symptom subscore. PVS was correlated with PRQ score negatively, and with PAS score positively. CONCLUSIONS: This study shows high PVS are associated with more severe psychotic symptoms and with clinical variables, such as disease process and premorbid adjustment, in some schizophrenics.

From January 1985, to June 1986, 7 cases in which supracondylar and intercondylar fractures of the femur were treated at our orthopaedic department using the Extensile Approach for an anatomical reduction and firm internal fixstion, show successful results in follow up stuides. l. All 7 cases were type III fractures of Neers classification. 2. Among the 7 cases treated surgically using the Extensile Approach, 5 cases showed excellent and good results and the remaining 2 csses showed one fair and one failed results. 3. Probably due to the additional open proximal tibia and patella fracture and delayed surgery from trauma one case had a fair results. The case which failed wss due to ipsilsteral ligamentous injuries and a nerve injury in addition to the femur fracture and slso the impossibility of early knee joint exercise due to associated injuries. 4. None of the results of the 7 csses had any relationship with the patients age. 5. One case of postoperative skin necrosis developed around the tibial tuberosity and was treated successfully by a cross leg flap. 6. In comminuted supracondylar and intercondylar fractures of the femur, the Extensile Approach is thought to be an excellent surgical technique by means of a wide surgical field for an anatomical reduction and firm internal fixation with the repair of associated ligamentous injuries.

Congenital pseudarthrosis of the tibia was accepted as one of the most difficult disease in respect of the frequency and treatment for the orthopaedists. Since April, 1984, we experienced 3 cases of congenital pseudarthrosis of the tibia, one 2 year-old boy involved left tibia only and the other 4 year-old female involved bilaterally, obtained solid bony union in all which were treated by massive surgical management that contained vascularized bone graft and electric stimulation. Several complications were faced such as refracture, valgus deformities of the ankle, skin irritation sign, angular deformities. But refracture was healed without delayed or nonunion by simple plaster cast immobilization. The vascularized bone graft snd electric stimulation is thought to be more improved methods for the treatment of congenital pseudarthrosis of the tibia. Althought solid bony union was obtained in congenital pseudarthrosis of the tibia, periodic follow-up and adequste management must be mandatory up to the end of the bony growth.

Paragonimus westermani mainly infests the lung parenchyma, and it is also causes ectopic parasitism of various sites, such as brain, liver and subcutaneous tissue but there have been no reports in literature about paragonimiasis infesting lumbar epidural space. A 58-year-old housewife complained of lumbago and radiating pain to both lower extremities for 20 years. Calcified extradural masses were found by preoperative plain X-ray, myelogram, and CT scan. Intraoperatively, cystic mass in the epidural space at L2-3 was found and confirmed to be paragonimiasis by histopathological study. A case of ectopic paragonimiasis in the lumbar epidural space at L2-3 level is presented.

Synovial chondromatosis is an uncommon benign lesion characterized by multiple cartilagenous and osteocartilagenous nodules of the synovium and loose bodies. The affection is monoarticular and most commonly involves the knee and has an unknown etiology. Of the five cases of synovial chondromatosis experienced by the authors, both knee joints were involved in a case, two the elbow joint, and one the proximal phalanx of the left middle finger. The diagnosis of synovial chondromatosis was made by the histopathological findings of the excised masses.
