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.

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.

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.

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.

PURPOSE: The purpose of our study is to evaluate the plain radiographic features of pulmonary tuberculosis in adult diabetic patients compared with those in patients without any underlying diseases. MATERIALS AND METHODS: We analyzed the chest PA and lateral views of 100 patients having active pulmonary tuberculosis;40 patients had diabetes mellitus and 60 patients had no other underlying diseases. images were assesed for anatomical distributions, extents of lesions, size and number of cavity and patterns radiographic findings. RESULTS: Diabetic tuberculosis had higher prevalence and wider involvement of unusual segments for the tuberculosis such as anterior segment, lingular segment of upper lobe and basal segment of the lower lobe, and they showed the tendency of having more cavities than those who had no other underlying diseases, but there were no meaningful differences in the cavity size between the two groups. CONCLUSION: Pulmonary tuberculosis in diabetic patients tends to have wider extent with unusual segmental involvement and multiple cavities than in the patients who had no other underlying diseases.

The scabies mite is an ectoparasite, which is able to infest humans. The incidence of scabies decreased during the past 20 years in Korea. However, the incidence is likely to increase again, and may be delayed or missed diagnosis recently. Its clinical presentation is typical, although in a host with compromised immune system, like the mentally retarded and elderly patients, the clinical presentation may be altered. Because a delay in diagnosis may induce rapid spread of the scabies mite, immediate diagnosis and treatment are necessary. We report two cases of scabies in elderly patients from different nursing homes. These patients were transferred to our center for treatment of pneumonia and chronic renal disease. They revealed pruritus and skin rashes after the treatment of further underlying diseases. We consulted to a dermatologist because of worsening symptoms, despite an application of medication with antihistamine and topical steroid, scabies was diagnosed. The symptom improved with topical 1% gamma-benzene hexachloride, an effective scabies drug. We suggest that geriatrists should suspect scabies who presents with pruritus that is persistent or resistant to conventional treatment, especially patients transferred from nursing homes.

A 73-year-old woman who presented with chest discomfort visited the emergency room. The 12-lead electrocardiography showed ST-segment elevation in II, III, and lead augmented vector foot. Emergent coronary angiography revealed a thrombus in the distal right coronary artery. Percutaneous coronary angioplasty with a stent was performed. After the procedure, persistent dyspnea occurred. Her chest computed tomography (CT) showed occlusion of the bilateral pulmonary artery. We could not find a source for the embolization or a hypercoagulable state. We started a course of dual antiplatelets with oral anticoagulants. Pulmonary embolism was resolved at follow-up chest CT scan. Aspirin, clopidogrel and warfarin were given for 6 months. The patient is doing well now 1 year after the episode.
