PURPOSE: To analyze clinical, radiological and pathological features as well as clinical outcome after surgical treatment of patients with secondary chondrosarcoma arising from osteochondroma(tosis). MATERIALS AND METHODS: We retrospectively reviewed clinical records, radiographs, pathologic slides of 14 patients. Nine patients were male and five were female. The mean age was 34 years. The mean follow-up period was 54 months. RESULTS: All patients had a history of previous mass since childhood or puberty. Preexisted osteochondroma was single in 3 patients and multiple in 10. Remaining 1 patient had multiple osteochondromatosis with enchondromatosis. MRI clearly provided thickness of cartilage cap, which was over 2 cm except in 2 cases. Chondrosarcoma was grade 1 in all except 1 case, which was grade 2. Wide excision was performed in 10 patients, marginal excision in 3 and amputation in 1. Twelve patients were doing very well without evidence of disease. Among 3 patients with marginal excision, 1 patient had local recurrence and 1 patient died of disease. CONCLUSION: Comprehensive understanding of clinical, radiological and pathological features of secondary chondrosarcoma is warranted for accurate diagnosis. The best result can be expected with early recognition of malignant change of osteohcondroma(tosis) and wide excision.

The objectives of this study are to investigate the prevalence of occupation related carpal tunnel syndrome(CTS) among workers in a condom industry; to analyse the sensitivity and specificity of clinical signs or symptoms such as hand diagram, Tinel's sign and Phalen's sign in carpal tunnel syndrome; and to test vibration threshold test using audiometry as a technically easy and noninvasive method in the diagnosis of carpal tunnel syndrome in stead of nerve conduction velocity(NCV). The study group was divided into exposed group(39 cases)and non-exposed group(48 cases) based on whether or not excessive use of wrist movements exist. 1. There are statistically significant differences in symptoms and signs of carpal tunnel syndrome such as hand diagram, Tinel's sign and Phalen's sign between exposed and non-exposed group(p<0.05). 2. Six cases(9 hands) were confirmed as carpal tunnel syndrome by NCV. Five cases(7 hands) belonged to exposed group, 1 case(2 hands) to nonexposed group. As there are significant differences in prevalence of carpal tunnel syndrome between two groups(p<0.05), excessive use of wrist in occupation is a risk factor of carpal tunnel syndrome. 3. When we use NCV as a gold standard in the diagnosis of carpal tunnel syndrome, sensitivity and specificity of hand diagram, Tinel's sign and Phalen's sign is as followed; hand diagram; sensitivity 88.9%, specificity 84.2%. Tinel's sign; sensitivity 55.6%, specificity 72.8%. Phalen's sign; sensitivity 14.3%, specificity 88.4%. Among above clinical signs and symptoms, hand diagram is the best clinical screening test. 4. The differences of vibration threshold between median and ulnar nerve at the same time are useful in the diagnosis of carpal tunnel syndrome but the time change of vibration threshold of median nerve over time are not sensitive enough. It is concluded that vibration threshold between median and ulnar nerve at the same time can be used as a supplementary or alternative criterion to indicate that the nerve dysfunction is located in the carpal tunnel.

Purpose: The purpose of this study is to identify the effect of nursing students' perception of emerging infectious disease, ethical awareness and nurse image on their career identity in a pandemic situation. Methods: Data were collected from 247 nursing students within universities of Daejeon, Gimcheon and Yeongdong area from May 18 to June 20, 2020. The data were analyzed using t-test, ANOVA, Pearson's correlation coefficient and regression analysis. Results: The subjects of this study had high level of perception of novel infectious disease (3.72±0.43), ethical awareness in pandemic situations (4.06±0.48), and nurse image (4.07±0.49), but low level of career identity (1.99±0.51). Career identify was significantly correlated with perception of novel infectious disease (r=.18, p=.005), ethical awareness in pandemic situation (r=.16, p=.011), and nurse image (r=.32, p<.001). However, excluding grade and residential area among the general characteristics, only the nurse image (β=.35, p<.001) was identified as a factor influencing career identity, and the explanatory power was 13.1%. Conclusion To increase the career identity of nursing students, it is necessary to raise professional nurses’ social awareness and develop a positive nurse image.

Subacute thyroiditis is a frequent benign thyroid disease associated with previous viral upper respiratory tract infection. Known complications of this disease are long-standing subclinical hypothyroidism, persistent anterior neck pain and rarely Graves disease. In general, thyroid abscess is an uncommon disease because of anatomic isolation of the gland and its rich system of drainage for blood and lymph. Especially, development of thyroid abscess in subacute thyroiditis is extremely rare phenomenan, but significant bad outcomes can be resulted. Its clinical BACKGROUND containes immune-suppressed state, anatomic defect, presence of underlying other thyroid disease and of non-thyroidal infectious foci. We experienced a case of subacute thyroiditis complicated with streptococcal thyroid abscess during glucocorticoid therapy. The patient was a 19-year-old female who was admitted due to anterior neck pain for 1 month. Typical subacute thyroiditis was suggested from initial laboratory findings including CBC, erythrocyte sedimentation rate, serum T3, T4, TSH levels, thyroid scan & thyroid uptake. But during oral prednisolone therapy, unexpected bacterial thyroid abscess was developed. We report this unusual case with review of literatures.

A 72-year-old man presented with incidentally found palpable abdominal mass of unknown duration. On admission, he had blood pressure of 120/80mmHg and pulse of 70 beats per minute. He consumed a pack of cigarettes per day for 45 years. He denied any prior chest pain episodes. The serum lipid profiles were within normal range. Electrocardiogram revealed sinus rhythm without ST-T wave change. Digital subtraction angiography revealed aneurysmal dilatation of both common iliac arteries to the proximal part of the external iliac arteries. Transthoracic echocardiography revealed normal left ventricular wall motion except a pseu-doaneurysm at the apex (Fig. 1). Color Doppler (Fig. 2) and intravenous contrast echocardiography (Fig. 3) showed free blood flow communication through the neck of the pseudoaneurysm. Coronary angiography revealed no significant luminal narrowing of coronary arteries. Left ventriculogram showed an aneurysm at the apex (Fig. 4). During the period of 8 months follow-up, the patient did not have any event or complain any symptom.

Regional anesthesia for Cesarean section is a popular anesthetic method and a subarachnoid injection of local anesthetics provides rapid onset and a reliable block. Furthermore, it maintains airway reflexes and consciousness of the parturient and is associated with less neonatal depression. Complications related with spinal anesthesia are most often postdural puncture headache, back pain, hematoma, abscess, paresthesia or motor weakness and very rarely, myoclonus. Generalized seizures as a complication following epidural anesthesia with bupivacaine has been reported, but rarely following spinal anesthesia. We present a case of a parturient who was well antenatally, but presented with generalized tonic-clonic seizures following delivery. Although the possible etiologic factors of these transient seizures after spinal anesthesia are difficult to clarify, we emphasize that careful airway monitoring after regional anesthesia is important.

Ictal spitting is an unusual manifestation that originates from the non-dominant hemisphere, but rarely from the dominant hemisphere. In the latter case, it has not been well defined as to whether symptomatogenic area for ictal spitting originates from the dominant hemisphere. We present a patient with ictal spitting. Intracranial EEG demonstrated a left hippocampal onset with propagation to the right hemisphere, and subsequent ictal spitting development. Even in dominant hemispheric seizures, the non-dominant hemisphere is a symptomatogenic area for ictal spitting.
