BACKGROUND: In order to restore severely attrited teeth properly, surgical intervention in the form of a crown-lengthening procedure may be required. And also, proper diagnosis and treatment sequencing is critical to obtain a successful results. Adequate diagnostic wax-up ensures good esthetics and healthy periodontal tissue. CASE DESCRIPTION: This clinical case report describes a diagnostically based protocol for restoration on mandibular anterior teeth with crown lengthening procedure and the treatment of partially edentulous mandible combined with an edentulous maxilla. In addition, the effort to prevent the combination syndrome was described. CLINICAL IMPLICATION: An interdisciplinary diagnosis and examination through visualization of the desired results ensure conservative and more predictable outcome.

PURPOSE: The purpose of this study is to describe the patterns of enhancement of the herniated lumbar disc with Gd-DTPA enhanced MR imaging. MATERIALS AND METHODS: Out of 65 patients, 103 lumbar discs diagnosed to be herniated by MR image were retrospectively analyzed. The MR imaging was performed with 1.5 T MR unit, using T1- and T2- weighted sagittal and axial spin echo techniques. Contrast- enhanced T1 weighted sagittal and axial images were performed after intravenous injection of Gadopentetate-dimeglumine(Magnevist, Shering) (0.1 mmol/kg). RESULTS: Contrast enhancement was seen in 66 cases(64%). Thirteen cases of bulging disc were not enhanced. Twenty-eight cases of protruded disc showed intraannular enhancement in 23 cases, peripheral linear and irregular enhancement in each of one case, and nonenhancement in three cases. Fifty-seven cases of extruded disc showed irregular enhancement in 14 cases, peripheral linear enhancement in 12 cases, peripheral ring enhancement in five cases and intraannular enhancement in five cases. All five cases of sequestered disc showed peripheral ring enhancement. CONCLUSION: Protruded discs show intraannular enhancement frequently and sequestered discs usually show peripheral ring enhancement. Enhanced MR imaging may be helpful to evaluate the type of herniated lumbar disc and relationship among disc material, nerve root and thecal sac.

PURPOSE: To assess the usefulness of MRI in preoperative diagnosis of congenital anorectal malformation MATERIALS AND METHODS: MR findings of 11 cases with surgically proved anorectal malformations were retrospectively reviewed and compared with operative findings, according to the level of atresia, the development of sphincter muscle, fistula and associated anomalies of other organs. RESULTS: Four of 11 cases were low type of anorectal atresia, 3 cases were intermediate type, and 3 cases were high type. There was one case of Currarino triad with low type of anorectal stenosis. MRI demonstrated the levels of atresia correctly in all cases and revealed fistulas in all high type of anomalies. Degrees of the development of the sphincter muscles were good in all cases of low types and fair in a case of intermediate type and an anorectal stenosis, whereas the development was poor in 2 cases of intermediate type and all 4 cases of high type. The associated anomalies in anorectal malformation were renal agenesis, congenital hip dysplasia and sacral defect with presacral teratoma in Currarino triad. CONCLUSION: MRI was a simple and useful study to confirm the level of atresia, fistula and associated anomalies in the diagnosis of the congenital anorectal malformation.

The osteopoikilosis is commonly known as harmatoma in which metaphyseal and epiphyseal area of long bones and the bone of pelvis, hands, feet and et al, contain islands of dense cortical bone with normal Harversian system without any symptoms. The radiologic findings of the osteopoikilosis is multitude of oval or well-circumscribed areas of increased density, 2 to 10 mm in size, in symmetrical distribution and normal uptake in bone scan. Buschke-Ollendorff syndrome, which is transmitted by autosomal dominant, is characterized by the association of osteopoikilosis and connective tissue nevi which are popular and symmetrically distributed lesions on chest, back, buttock, thigh or arm. Authors report three Buschke-Ollendorff syndrome, studied by CT scan, MRI, bone scan and bone and skin biopsy, among five patients associated with osteopoikilosis found by simple radiologic study from ten members in one family with their pedigree.

BACKGROUND: Orbital resorbable mesh plates are adequate to use for isolated floor and medial wall fractures with an intact bony buttress, but are not recommended to use for large orbital wall fractures that need load bearing support. The author previously reported an orbital wall restoring surgery that restored the orbital floor to its prior position through the transnasal approach and maintained temporary extraorbital support with a balloon in the maxillary sinus. Extraorbital support could reduce the load applied on the orbital implants in orbital wall restoring surgery and the use of resorbable implants was considered appropriate for the author’s orbital wall restoring technique. METHODS: A retrospective review was conducted of 31 patients with pure unilateral orbital floor fractures between May 2014 and May 2018. The patients underwent transnasal restoration of the orbital floor through insertion of a resorbable mesh plate and maintenance of temporary balloon support. The surgical results were evaluated by the Hertel scale and a comparison of preoperative and postoperative orbital volume ratio (OVR) values. RESULTS: The OVR decreased significantly, by an average of 6.01% (p < 0.05) and the preoperative and postoperative Hertel scale measurements decreased by an average of 0.34 mm with statistical significance (p < 0.05). No complications such as buckling or sagging of the implant occurred among the 31 patients. CONCLUSION: The use of resorbable mesh plate in orbital floor restoration surgery is an effective and safe technique that can reduce implant deformation or complications deriving from the residual permanent implant.

A 36-year-old female patient with aplastic anemia developed massive hemoptysis and was placed on ventilator support. However, airway obstruction by blood clots triggered desaturation and ventilator malfunction. Manual ventilation was initiated to improve oxy-genation, and emergency flexible bronchoscopy was performed to clear the airway. Nevertheless, the patient developed extensive subcutaneous emphysema, pneumothorax, and pneumomediastinum.

Left atrial thrombus is frequently associated with rheumatic mitral valvular heart disease. Left atrial thrombus is usually attached to the atrial wall, but rarely it is freely floating in the cavity. In that case the patient may present with the symptoms of acute hemodynamic decompensation due to the so-called "hole-in-one" effect or multiple systemic embolism. We report a case of multiple systemic embolism associated with left atrial free-floating ball thrombus in mitral valvular heart disease.

BACKGROUND: This study is aimed at the pathoanatomic correlates of depression and anxiety in acute stroke patients including subcortical lesion(periventricular hyperintensity, deep white matter hyperintensity, subcortical gray matter hyperintensity). METHODS: Sixty nine patients with acute stoke were recruited. Their brain lesions were measured using Brain MRI. Depressive or anxiety symptoms were rated by Beck depression inventory(BDI) or Beck anxiety inventory, respectively. RESULTS: There were significant correlation between depression and periventricular hyperintensity and deep white matter hyperintensity in acute stroke patients. There are no significant pathoanatomic correla- tions between anxiety and brain lesions on MRI. CONCLUSION: Our findings suggest that the white matter lesion may increase the risk of depression after stroke. Prevention of asymptomatic cerebrovascular lesion could decrease the risk of depression in acute stroke patients as well as the risk of stroke.

OBJECTIVES: The cerebrovascular diseases including stroke have become prevalent in Korea, ranking first as the cause of death in the aged. The quality of life (QOL) in stroke patients has been studied with growing interest since every aspect of life after stroke is influenced by the sequelae of this illness. This study aimed at 1) describing QOL of stroke patients and 2) identifying predictors of two month QOL after the event in stroke survivors. METHOD: WHO QOL scale was used to evaluate two month QOL after the stroke in 69 ischemic stroke patients. Data on age at the stroke event, sex, education level, brain MRI (magnetic resonance imaging) findings, symptoms of depression and anxiety, and neurologic disabilities were collected. Analyses were performed to explore the predictors of two month QOL. RESULTS: Stroke survivors with higher number and volume of frontal cortex lesions had lower two month QOL. Also, patients with more severe subcortical gray matter lesions had significantly lower two month QOL. Stroke patients with depression at the event had lower two month QOL than patients without depression. CONCLUSION: Lesions in frontal cortex and subcortical gray matter hyperintensities on MRI T2 images and depression in acute phase were of paramount importance in predicting two month QOL. Accurate and prompt neurologic and psychiatric interventions are required to improve QOL after stroke.
