Low-grade cribriform cystadenocarcinoma (LGCCC) of the salivary gland is a rare tumor. We report the cytologic features and histologic correlation of a patient with LGCCC. A 57-year-old man had a hardly palpable, nontender mass in the right cheek area followed over nine months. Radiologic analysis revealed a 1.2 cm multiseptated, cystic, solid nodule in an anterior superficial lobe of the right parotid gland. Fine-needle aspiration cytology revealed many irregular overlapping sheets or clusters of ductal epithelial cells forming solid, pseudopapillary, and cribriform architectures. Nuclei of the tumor cells revealed inconspicuous atypia with minimal size variation. On the basis of these findings, we confirmed a diagnosis of ductal epithelial proliferative lesion, favoring neoplasm, with uncertain malignant potential. Tumor excision was performed, revealing a tiny multicystic nodule (0.7 cm). Histopathologically, this tumor showed the characteristic morphology of LGCCC. This is the first report of cytomorphological findings of LGCCC in Korea.

Acute focal bacterial nephritis (AFBN), synonymous with acute lobar nephronia (ALN) or focal pyelonephritis, is an inflammatory mass without liquefaction caused by severe acute bacterial infection of kidney. Unless treated effectively, progression to a renal abscees may ensue. Clinically, AFBN presents as acute pyelonephritis, and radiologically, as focal swelling or mass. The distinction between AFBN and renal abceess or even tumor may be confusing and difficult. Ultrasonography and computerized tomography(CT) aid in establishing the correct diagnosis. However, the appearance of AFBN on sonography and CT is by no means pathognomonic. Benign or malignant renal tumors may have a similar appearance. With the clinical history, a high index of suspicion, and follow-up studies after institution of medical treatment may further aid in the differentiation. Herein we report 2 cases of AFBN, which were presented as renal masses.

Most currently available statins are associated with an increase with risk of myositis, including rhabdomyolysis. Myopathy is believed to be caused by interference in the cytochrome P450 3A4 enzyme system, which results in a marked increase in reductase activity. Cerivastatin, a new synthetic HMG-CoA reductase inhibitor, is a safe, well-tolerated effective drug for the treatment of patients with dyslipidemia. The drug is metabolized by the cytochrome P450 3A4 and cytochrome P450 2C8 hepatic isoenzymes. Because of this dual metabolic pathway, it has been suggested that cerivastatin is less subject to drug-todrug interactions. We describe a 60-year-old woman with rhabdomyolysis and localized myositis, after she had taken cerivastatin(lipobay, 0.3 mg/day) and gemfibrozil(lopid, 500 mg/day) for 1month.

High tibial osteotomy is a useful procedure in the treatment of early stage osteoarthritis of the knee which is confined to the medial compartment. But long term follow-up study of high tibial osteotomy has not been provided yet and its prerequisite for a successful result still remains unrevealed. Since the osteoarthritis can progress after the osteotomy, it may result in the loss of correction and recurrence of pain and require conversion to total knee replacement arthroplasty. We studied clinically and radiologically the long term result of high tibial osteotomy in 11 patients(16 knees) who had been treated at the Department of Orthopaedic surgery of Seoul Paik Hospital during the period from January, 1978 to May, 1989, and follow-up for longer than 4 years. Preoperative mean varus angle was 6.4 degrees and immediate postoperative mean valgus angle was 8.6 degrees and final mean valgus angle was 4.7 degrees. The average loss of correction angle was 3.9 degrees. At 2-year follow-up, the results of 16 knees were as follows; excellent in six knees, good in seven knees. The final results at average 7.2-year follow-up were excellent in four knees, good in six knees and one knee was converted to total knee replacement arthroplasty. The results showed deterioration of clinical results and loss of correction with time after osteotomy. However, in more than half of the cases the results were good or excellent at the final follow-up, We, therefore, conclude that high tibial osteotomy is still a useful procedure in osteoarthritis of the knee if performed with a precise surgical technique and an adequate overcorrection more than 10 degrees.

PURPOSE: In many other countries, based on research, recombinant tissue plasminogen activator (r-tPA) has been approved for the treatment of acute ischemic strokes. However, in Korea, little research has been done till now, in spite of using r-tPA widely. We sought to assess the feasibility and the efficacy of treatment and to evaluate the prognosis and complications at the violation of using r-tPA. Our study was compared with other previous studies. METHODS: A retrospective review is presented of 25 the cases of patients with acute ischemic stroke treated with rtPA according to the National Institutes of Neurological Disorders and Strokes (NINDS) protocol. We classified the groups by protocol violation (time, blood pressure, and computed tomography). We then analyzed neurologic outcomes by using the National Institutes of Health Strokes Scale (NIHSS) and complications based on whether or not intracerebral hemorrhage (ICH) had occurred. RESULTS: Of the 25 patients (mean age: 57 males: 19), 6 had time violation (onset time > 180 min), 4 had blood-pressure violation (systolic BP > 185 mmHg), 5 had CT violation (low density at initial CT). The NIHSS score improved in 64% of all patients after 24 hours. However, improvement was lower in the case of deviation present than it was in the case of deviation absent (time, blood pressure, and CT, respectively, 20%, 50%, and 40%; p-value respectively 0.0274, 0.8350, and 0.4125). ICH occurred in 6 cases, but in cases of deviation present, ICH occurred at a greater frequency. CONCLUSION: Our safety and feasibility of outcome compared favorably with NINDS and other previous studies. In addition, we confirmed that the presence of protocol deviation was associated a poor outcome.

Sacrococcygeal teratoma is a rare tumor, it occurs once in every 40,000 live births. Most of the reported cases appear in female infant (M:F=1:4). They deserve clinical attention because they are potentially malignant and are curable if diagnosed and treated early. The patients may have associated congenital anomalies. This patient has spina bifida cystica in lower sacrum. Brief review of related literature is included in the report.

Murine (endemic) typhus is a zoonotic infection caused by Rickettsia typhi (formerly known as Rickettsia mooseri). Rickettsia typhi is an obligate intracellular organism that multiplies within the cytoplasm of mainly endothelial cells. It is transmitted from rats by injection of contaminated flea feces into the skin of the host. The disease manifests itself with the gradual onset of fever, myalgia, and headache appearing 7-14 days after infection. A maculopapular rash is found in some patients (proportions ranging from 20 to 80% in different series). We report a rare case of murine typhus with presentation of hemorrhagic vesicles and dyspnea which was treated at our emergency department, and we give a brief review of the literature.
