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.

PURPOSE: The aims of this study were to document our single-center experience with pediatric acute fulminant myocarditis (AFM) and to investigate its clinical features and short-term outcomes. METHODS: We performed a retrospective chart review of all children <18 years old who were diagnosed with AFM between October 2008 and February 2013. Data about patient demographics, initial symptoms, investigation results, management, and outcomes between survivors and nonsurvivors were collected. RESULTS: Seventeen of 21 patients (80.9%) with myocarditis were diagnosed with AFM. Eleven patients (64.7%) survived to discharge, and 6 (35.3%) died. Electrocardiography on admission revealed dysrhythmia in 10 patients (58.8%); of these, all 7 patients with a complete atrioventricular block survived. Fractional shortening upon admission was significantly different between the survivors (16%) and nonsurvivors (8.5%) (P=0.01). Of the serial biochemical markers, only the initial brain natriuretic peptide (P=0.03) and peak blood urea nitrogen levels (P=0.02) were significantly different. Of 17 patients, 4 (23.5%) required medical treatment only. Extracorporeal membrane oxygenation (ECMO) was performed in 13 patients (76.5%); the survival rate in these patients was 53.8%. ECMO support was initiated >24 hours after admission in 4 of the 13 patients (30.7%), and 3 of those 4 patients (75%) died. CONCLUSION: AFM outcomes may be associated with complete atrioventricular block upon hospital admission, left ventricular fractional shortening at admission, time from admission to the initiation of ECMO support, initial brain natriuretic peptide level, and peak blood urea nitrogen level.

Ophthalmoplegia may accompany herpes zoster ophthalmicus(HZO). A 60-year-old woman with rheumatoid arthritis suffered from HZO in the right side consecutively developed a mydriasis and abduction deficit in the right eye. CSF examination revealed pleocytosis and increased protein, while magnetic resonance imaging of the brain was normal. She was treated with intravenous acyclovir for 7 days. Ophthalmoplegia was completely resolved over the following 8 weeks, but mydriasis persisted.

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.
