The medial collateral ligament is the most commonly injured ligamentous structure of the knee. The management of the medial collateral ligament injuries were divided into surgical and conservative treatment. More recently, many investigators reported that isolated medial collateral ligament injuries did well under non-operative treatment. So, arthroscopic examination of the knee to rule out other intraarticular pathologic conditions such as cruciate ligament injuries, meniscal tear and osteochondral lesion is essential. From October 1993 to April 1995, we treated 45 cases of Grade III medial collateral ligament injuries and arthroscopic finding for cruciate ligament, meniscus, bony structure were analized in these cases. The result were as follows; 1. Anterior cruciate ligament injury:37.5% in +1 degree, 42.8% in +2 degree, 86.7% in +3 degree 2. Posterior cruciate ligament injury:12.5% in +1 degree, 13.4% in +2 degree, 33.3% in +3 degree 3. Meniscal injury:12.5% in +1 degree, 21.3% in +2 degree, 33.4% in +3 degree 4. Medial capsular ligament injury was more frequent and severe in the meniscofemoral ligament than in the meniscotibial ligament, but that finding was not correlated with degree of medial instability.

Inflammatory pseudotumor, originally described in the lung, is a relatively rare tumor-like lesion that occurs in various organs and tissues. It is usually well demarcated from the surrounding tissue, however it can be unfortunately resected as a malignant tumor. A few inflammtory pseudotumor in the kidney have been reported in English literature, but there have been no reports in Korea. We report a case with inflammatory pseudotumor of the kidney. A 48 year old woman had an intermittent flank pain on the right side. An ultrasonographic study suggested a renal cell carcinoma and a nephrectomy was done. Grossly, there were two separate masses with a well demarcated yellowish appearance, measuring 2.3 cm and 1.3 cm in diameter, respectively. Histologically, they were composed of smooth muscle actin positive spindle cells and a large number of foamy histiocytes, lymphocytes, and plasma cells in the fibrotic backgound.

Midline malignant reticulosis is a relentlessly progressive, localized, destructive inflammatory process of upper respiratory tract including the nose, nasopharynx, palate, paranasal sinuses, and midface. Histologically, it is characterized by a dense aceumulation of pleomorphic mononuclear cells with an admixture of inflammatory cells. We report a case of midline malignant reticulosis developed in a 64-year-old man, who showed a serosanguineous nasal discharge, perforation of nasal septum, persistent ulceration of hard palate, and disseminated lesions on the abdominal skin, which was confirmed by histopathalogical examination. In addition we studied infiltrated cells with atypical nuclei by immunohistochemical staining with a pannel of monoclonal antibodies. The results revealed that the atypical cells expressed the T-cell marker, but not the macrophage and B-cell marker.

The authors studied the effect of insufflation of oxygen at 5 cmH2O into the nonventilated lung on the arterial oxygenation in the thoracotomy patients(n=14) who showed PaO2 below 100 mmHg or oxygen saturation below 95% during one-lung ventilation. When applying CPAP 5 cmH2O to the collapsed lung, we inflated the collapsed lung with reservoir bag that is one of the equipment of self made CPAP device. Hemodynamic parameter(mean arterial pressure and heart rate), arterial blood gas analysis and calculated shunt fraction was collected 10, 20, 30min after applying CPAP. PaO2 was significantly increased from 76+/-20mmHg to 180+/-66 (mean+/-SD) and shunt fraction was significantly decreased from 43.5+/-5.6% to 31.5+/-4.9% at CPAP 10 min. There was no significant difference in the PaO2 and shunt fraction between CPAP 10, 20 and 30 min. Heart rate was also significantly decreased with CPAP compared to pre-CPAP value. Other parameter(mean arterial pressure, PaCO2) was not changed with CPAP. The authors conclude that CPAP 5 cmH2O to the nonventilated lung is effective to improve oxygenation when hypoxemia occurs during one-lung ventilation.

We report four cases of spontaneous intracranial hypotension that were investigated by radionuclide cisternography Tc-99m-diethylenetriamine pentaacetic acid radionuclide cisternography of all our patients showed direct sign of cerebrospinal fluid leakage as well as indirect signs of less activity than expected over the cerebral convexities and rapid appearance of bladder activity. The headache of all patients was eventually controlled with bed rest and hydration.

Although total meniscectomy had been performed as a treatment of meniscal tear, many published articles reported progression of the degeneration process and development of the osteoarthritis after meniscectomy. Meniscal repair has been performed increasingly, with the increased knowledge of the biomechanical properties of the meniscus. However, resection of the meniscus is still needed for irreparable tear and should be performed as minimally as possible to maintain the important functions of the meniscus. When substantial meniscal tissue is resected, meniscal allograft transplantation is considered to be a therapeutic option for young active patients to prevent the progress of degenerative change of the cartilage. In this review, indications and outcomes after meniscectomy, meniscal repair, and meniscal transplantation for the treatment of the meniscal injury are discussed.
