This study analyzed 88 patients who sustained a cervical spine injury during the past 4 years(Jan, 1993-May, 1996) in whom had 33 anterior, 21 posterior interventions were underwent and 34 remaining patients recieved conservative treatment with halovest. In 45 cases of upper cervical injuries, 16 operations were done. Among these, anterior approach was used in 3 patients and posterior approach in 13 patients. In 43 cases of lower cervical injuries, 39 operations were done. The anterior approach was used in 30 patients, posterior approach in 9 patients, and bilateral approached in remaing 4 cases. For patients with a predominent posterior ligamentous or osteoligamentous lesion, we selected anterior approach, when closed reduction was possible. Whenever the facet joint remained interlocked, a posterior approach was chosen. This report does not mentioned priority of anterior procedure at any case. Although clinical experience does not support the experimental data, we examined the reliability of anterior approach with use of internal fixation.

Background:
Cutaneous metastasis (CM) is the spread of cancer cells from a primary site to the skin and is rarely the first sign of silent cancer. We investigated the clinicopathological characteristics of CM from internal malignancies in Korean patients treated at our institution over 20 years.
Methods:
The clinicopathological findings of 112 patients (62 females, 50 males) with CM diagnosed at Yeungnam University Hospital between 2000 and 2020 were retrospectively reviewed.
Results:
Mean patient age was 58.6 years (range, 26 to 87 years), and the most common primary cancer site was breast (74.2%) in women and lung (36.0%) in men. Ninety-six patients (85.7%) presented with CM after primary tumor diagnosis. CM from the lung or biliary tract usually occurred within 2 years of primary tumor diagnosis, whereas metastases from the breast and kidney occurred several years later. The chest, abdomen, and scalp were common sites of CM. Breast cancer usually metastasized to chest skin, while gastrointestinal tract cancers commonly metastasized to the abdomen. The scalp was a common location for CM from various tumors. The most common dermatologic presentations were nodules and masses. Immunohistochemical studies helped identify underlying malignancies when primary tumors were unknown.
Conclusions
The relative frequency of CM parallels the overall incidence of primary malignant tumors, and CMs usually occur at anatomic sites close to the primary tumor. CM can be diagnosed based on clinical, radiological, and histological features; however, immunohistochemical study is required in some cases.

OBJECTIVES: Neurotensin (NT), of which functions are evoked by its interaction with neurotensin receptors (NTR), coexists with mesolimbic dopamine and regulates endogenous dopamine release. Recent studies have shown that NT with NTR exerts neuroleptic-like activity within the central nervous system and may play an important role in the pathogenesis and in the treatment of schizophrenia. We have examined the genetic association between schizophrenia and tetranucleotide repeat polymorphism in the 3'-flanking region of the NTR gene to investigate the possible contribution of the NTR gene to the schizophrenia susceptibility. METHODS: Among 23 alleles identified, the subjects were 120 patients (male 91, female 29) with schizophrenia and 106 normal healthy controls (male 84, female 22). They were unrelated native Korean. PANSS was used to determine positive or negative subgroup in the schizophrenic patients.Using polymerase chain reaction and polyacrylamide gel electrophoresis, tetranucleotide repeat polymorphism (CCTT and CTTT) in the 3'-flanking region of NTR gene was observed. For a comparison of NTR gene's allelic frequencies between patients with schizophrenia and normal healthy controls, chi-square test and Bonferroni's correction was performed. RESULTS: The frequency of A10 allele (base pair size=399) was significantly higher in normal healthy controls than schizophrenia (x2=16.4902, df=1, p<.000). In the comparison between schizophrenic patients with negative symptoms and normal controls, the frequency of A10 allele was significantly higher in normal healthy control subjects than patients with schizophrenia (x2=21.33, df=1, p<0.001). In the case of male, the frequency of A10 allele of schizophrenia was significantly higher than normal controls (x2=13.71, df=1, p<0.001). CONCLUSIONS: NTR gene was negatively associated with schizophrenia. NTR gene's tetranucleotide repeat polymorphism may provide some protective function against schizophrenia.

Intramural pregnancy implanting in the previous cesarean section scar is one of the rarest form of an ectopic pregnancy and probably the most dangerous form because of its risk of rupture and hemorrhage. For its sonographic diagnosis, the gestational sac should be in the anterior wall of uterine isthmic portion, there should be no myometrium between bladder and gestational sac, and it should be verified that uterine cavity and cervix should be isolated from gestational sac. For young patients who wish to maintain their fertility, an earlier diagnosis and more conservative treatment are desirable. We have recently experienced a case of intramural pregnancy implanting in the scar of cesarean section, treated with systemic methotrexate injection. So, we report this case with a brief review of the literature.

Purpose:
This study aimed to gain better understanding of the importance of dental prosthesis order platform services and to identify the essential elements for their enhancement and wider adoption among dental professionals.
Materials and Methods:
A survey was conducted to assess the perspectives of dentists, dental technicians, dental hygienists, and dental industry professionals toward dental prosthesis ordering and associated platform services (a total of 53 respondents). The questionnaire was devised after an expert review and assessed for reliability using Cronbach’s alpha coefficient. Factor analysis revealed that 57 factors across five categories accounted for 88.417% of the total variance. The survey was administered through an online questionnaire platform, and data analysis was conducted using a statistical software, employing one-way analysis of variance and Tukey’s honestly significant difference test (α = 0.05).
Results:
The essential elements identified were accurate information input, effective communication, delivery of distortion-free impressions, convenience in data transmission and storage, development of stable and affordable platform services (P < 0.05). Furthermore, significant differences were observed in the importance of these items based on age, dental profession, and career experience (P < 0.05).
Conclusion
The dental prosthesis ordering platform services, the requirements of dental personnel were stability, economic efficiency, and ease of transmitting and storing prosthesis data. The findings can serve as important indicators for the development and improvement of dental prosthesis order platform services.

Scleroderma renal crisis is defined as rapidly progressive renal failure and/or new onset of malignant hypertension during the course of systemic sclerosis. Most patients show clinical features of malignant hypertension, but there have been several reports of normotensive renal crisis. We have experienced a 63 year old female patients with acute renal failure due to scleroderma renal crisis who did not show the clinical features of malignant hypertension. She had taken steroid for the treatment of degenerative osteoarthritis and gradually developed shortness of breath and edema. Her blood pressure on admission was 150/90 mmHg and easily controlled by diuretics. Renal biopsy showed onion-skin appearance in the interlobular arteries with varying degree of tubulointerstitial changes. Her renal function rapidly deteriorated despite ACE inhibitor therapy and cytotoxic therapy had to be initiated because of progressive interstitial pneumonitis and myocarditis. We describe a patient with scleroderma renal crisis who did not show the clinical features of malignant hypertension following steroid treatment.

Atlato-axial instability is a serious condition that often requires operation. Atlanto-axial subluxation may cause severe symptoms; and threaten the intergrity of the spinal cord, leading to quadriplegia or sudden death. A techique of combining C1-C2 posterior screw fixation with a supplemental bone wire fusion has been advocated for the management of atlantoaxial instability. It was used in 9 patients with this disorder. Patients ages ranged from 20 years to 52 years; follow-up period ranged from 3 to 16 months with a mean of 9.8 months. All nine patients gained immediate rigid fixation of C1,2 with this technique. Of these 9 patients, instability occurred due to trauma in seven, os odotoideum in one and os odontoideum with trauma in another one. One patient was presented with nonunion and C1,2 instability after a Halovest applications a result of type II odontoid fracture. All 9 patients were placed in a philedelphia collar for 12weeks and all achieved solid fusion. Posterior atlantoaxial facet screw fixation provides immediate multidirectional rigid fixation of C1,2 and is mechanically superior to siring or clamp fixation. This technique maximizes success without the need for a supplemental rigid external orthosis.

PURPOSE: The purposes of this study were to evaluate the usefulness and limitations of chest radiographs in scoliosis screening and to compare these results with those of thoraco-lumbar standing radiographs (TLSR). MATERIALS AND METHODS: During Korean conscription, 419 males were retrospectively examined using both chest radiographs and TLSR to confirm the scoliosis and Cobb angle at the Regional Military Manpower. We compared the types of spinal curves and Cobb angles as measured from different radiographs. RESULTS: In the pattern of spinal curves, the overall matching rate of chest radiographs using TLSR was about 58.2% (244 of 419 cases). Cobb angle differences between chest radiographs and TLSR with meaningful difference was observed in 156 cases (37.2%); a relatively high proportion (9.5%) of Cobb angle differences more than 10 degrees was also observed. The matching rate of both spinal curve types and Cobb angle accuracy between chest radiographs and TLSR was 27.9% (117 among 419 cases). Chest radiographs for scoliosis screening were observed with 93.94% of sensitivity and 61.67% of specificity in thoracic curves; however, less than 40% of sensitivity (38.27%, 20.00%, and 25.80%) and more than 95% of specificity (97.34%, 99.69%, and 98.45%) were observed in thoraco-lumbar, lumbar, and double major curves, respectively. CONCLUSION: The accuracy of chest radiographs for scoliosis screening was low. The incidence of thoracic curve scoliosis was overestimated and lumbar curve scoliosis was easily missed by chest radiography. Scoliosis screening using chest radiography has limited values, nevertheless, it is useful method for detecting thoracic curve scoliosis.
