Pellegrini-Stieda's disease is a post-traumatic disorder of the knee. It is characterized by a crescentric-like bony formation in the region of the medial condyle of the femur, which usually makes its appearance upon roentgenographic examination three or more weeks after injury to the knee. During the three and a half years from January 1979 to July 1982, eleven patients were treated by conservative method and only one patient was treated by operation. The results were as follows; l. All give a history of trauma. 2. The major findings in this disease were pain in motion, local tenderness, and limitation of motion. 3. In roentgenographic findings of these cases, we noted the followings: 1) The most common site of the calcification was the proximal area of the tibial collateral ligament. 2) In seven cases (58%), the evidence of calcification was noted in 4 weeks to 12 weeks following original trauma. 3) Eight cases (67%) showed a radiolucent area from 0.5 to 3mm in thickness between the bony shadow and the femur. 4) Eight cases (67%) showed a crescentric shape of calcified area. 5) In seven cases (58%), the size of calcified mass was 1.5 to 3.5cm in length and 1 to 3mm in width. The mean size of calcified mass about 3cm in length and about 2.5mm in width. 4. Eleven cases were treated conservatively and one case was treated operatively. The results were satisfactory, and all patients were able to return to their works.

Objectives: . Otitis media is a common infection worldwide. Owing to the limited number of ear specialists and rapid development of telemedicine, several trials have been conducted to develop novel diagnostic strategies to improve the diagnostic accuracy and screening of patients with otologic diseases based on abnormal otoscopic findings. Although these strategies have demonstrated high diagnostic accuracy for the tympanic membrane (TM), the insufficient explainability of these techniques limits their deployment in clinical practice. Methods: . We used a deep convolutional neural network (CNN) model based on the segmentation of a normal TM into five substructures (malleus, umbo, cone of light, pars flaccida, and annulus) to identify abnormalities in otoscopic ear images. The mask R-CNN algorithm learned the labeled images. Subsequently, we evaluated the diagnostic performance of combinations of the five substructures using a three-layer fully connected neural network to determine whether ear disease was present. Results: . We obtained the receiver operating characteristic (ROC) curve of the optimal conditions for the presence or absence of eardrum diseases according to each substructure separately or combinations of substructures. The highest area under the curve (0.911) was found for a combination of the malleus, cone of light, and umbo, compared with the corresponding areas under the curve of 0.737–0.873 for each substructure. Thus, an algorithm using these five important normal anatomical structures could prove to be explainable and effective in screening abnormal TMs. Conclusion . This automated algorithm can improve diagnostic accuracy by discriminating between normal and abnormal TMs and can facilitate appropriate and timely referral consultations to improve patients’ quality of life in the context of primary care.

Primary small cell carcinomas of the prostate are rare, and their histogenesis and clinical behavior remain poorly defined. The origin of small cell carcinoma remains uncertain, but several hypothesis has been put forward, one of this is that the tumor is derived from the argentaffin or argyrophil cells normally present in the prostate, and the other is that arises from the totipotential basal or reserve cells of the prostatic acini. Primary small cell carcinoma of the prostate is a highly aggressive tumor. causing widespread metastasis and early death. The mean survival is 5 to7 months after diagnosis of the small cell carcinoma regardless of the proportion of small cell component or cell size. We report one case of primary small cell carcinoma of the prostate with brief review of literatures.

Protothecosis is a rare cutaneous soft tissue infection caused by the genus prototheca, most commonly Prototheca wickerhatmii. An 80-year-old woman has had a painful or tender, non-healing, eczematous plaque on the extensor surface of the left forearm for 4 years. A biopsy specimen revealed the characteristic thick-walled morulalike sporangia in the dermis. P. wickerha mili was isolated in the culture and the biochemical studies. Electron microscopic examination showed the thick-walled spores containing dark dense bodies and amyloplasts. Oral itraconazole therapy for 4 weeks resulted-in a marked improvement of the skin lesion.

Spine diseases are common and exhibit several causes, including degeneration, trauma, congenital issues, and other specific factors. Most people experience a variety of symptoms of spine diseases during their lifetime that are occasionally managed with conservative or surgical treatments. Accurate diagnosis of the spine pathology is essential for the appropriate management of spine disease, and various imaging modalities can be used for the diagnosis, including radiography, computed tomography (CT), magnetic resonance imaging (MRI), and other studies such as EOS, bone scan, single photon emission CT/CT, and electrophysiologic test. Patient (or case)-specific selection of the diagnostic modality is crucial; thus, we should be aware of basic information and approaches of the diagnostic modalities. In this review, we discuss in detail, about diagnostic modalities (radiography, CT, MRI, electrophysiologic study, and others) that are widely used for spine disease.

Postoperative total blindness was seen in a 48 year old male who had a laparotomy for traumatic perforation of intestine. General inhalation anesthesia of ether-oxygen-mask with semiclosed system was applied after initial ketamine administration. This unhappy ocular complication could be occur secondary to excessive prolonged external compression to eyeballs with mask or/and prolonged postoperative hypotension.

BACKGROUND: Much time and cost have been consumed for just a treatment of a simple disease and inappropriate management has taken place because of misjudgement by laymen. To establish a desirable health care system, need for the usual-medical-provider system (U.MP. system) has been suggested. This study was performed to find some data that would be helpful to establish the U.MP. system by surveying some factors influencing on choosing care providers of children. METHODS: 440 questionnaires were gathered from surveys administered to the parents of the students in a primary school. The period for study was 1 week of September in 1999 and the response rate was 88.0%. The questionnaire was composed of sociodemographic variables, a question for having U.MP. and some factors related with choosing U.MP. RESULTS: The fourth and fifth decade of age showed higher proportion for having U.MP. than sixth decade. The proportion of having U.MP. was also higher in respondents with higher educational attainment and higher income. The proportion of visiting local clinics or hospitals was about 65.7% in groups having U.MP., whereas the proportion was about 41.5% in group not having U.MP., The frequency of visiting local clinics or hospitals for a year was higher for groups having U.MP., compared with groups not having U.MP.. The factors related with choosing U.MP. were `doctors who explain the disease in detail and easily', `doctors who provide care meticulously', and `effective treatment'. CONCLUSION: To establish the U.MP. system, a kinder attitude and care would be necessary for doctors who will provide care to the patients and their family.

PURPOSE: This study has been conducted in order to examine the oral health status and dental prostheses status, and the effects of dental prostheses to the oral health related quality of life among the elderly using social welfare centers. MATERIAL AND METHODS: For this purpose, the researcher conducted a questionnaire survey and oral examination of 275 samples of old persons using 7 social welfare centers located in Daejeon metropolitan city. The oral health related quality of life was measured by GOHAI (Geriatric Oral Health Assessment Index). RESULTS: 1. The less age and the more education and the more subjective economic status and living with spouse of family status, the higher GOHAI showed. 2. Mean age of first using of removable denture is 62.11 years old and average life cycle of removable denture is 10.76years. 57.5% of study subjects use removable denture and complete denture user of study subjects are 13.8%. 3. In the case that they use fixed prostheses rather than removable ones and in the complete denture they use both sides (upper and lower) rather than single side, showed higher GOHAI. 4. In the case that they showed higher degrees of satisfaction with dental prostheses and can use them always and showed no necessity for new dental prostheses and denture adaptation is good, GOHAI showed higher. CONCLUSION: In order to improve oral health related quality of life among the elderly who have many missing teeth, it is required to restore their masticatory ability to the normal level by restoring the missing teeth which has lost its function through providing proper dental prostheses.

PURPOSE: In general, sinusitis in children is diagnosed by clinical symptom and paranasal sinus x-ray. Sinus plain x-rays in children is simple, inexpensive, and speedy. However, it requires proper interpretative techniques, because different development of each sinus, soft tissues overlying sinuses and bony structure require precise diagnosis. This study was conducted to compare plain x-rays with OMU CT scans. METHODS: From September 1996 through August 1997, thirty nine patients who were diagnosed as sinusitis based on clinical symptoms and plain x-rays at the pediatric department of Seoul Adventist Hospital were studied. Water's view, Caldwell's view and lateral view were taken for the plain x-rays with concurrent OMU CT scans prior to treatments. RESULTS: Ten cases (25.6%) out of 39 patients showed posterior nasal drip and fourteen cases (35.9%) showed nasal obstruction. Twelve cases (30.8%) were related to allergic diseases and seven cases (58.3%) among these 12 cases were bronchial asthma. Sensitivity of plain x-ray were 88.5+/-12.9% for maxillary sinuses, and 59.9+/-13.65% for ethmoidal sinuses. CONCLUSION: When maxillary sinusitis is suspected, plain X-ray for maxillary sinuses is enough to diagnose sinusitis, but for ethmoidal sinuses it may be underestimated or overestimated in comparison with OMU CT scan. Ethmoidal sinusitis requires careful diagnosis and follow-up because it plays important roll for chronic sinusitis due to its structure. Therefore, we recommends OMU CT scan to diagnose paranasal sinusitis of children with plain X-ray.
