Tolosa-Hunt Syndrome with Multiple Orbital Myositis in a Patient with Crohn’s Disease

Purpose@#We report a case of Tolosa-Hunt syndrome with multiple orbital myositis identified via orbital magnetic resonance imaging in a patient with Crohn's disease who developed right eye pain and binocular horizontal diplopia.Case summary: A 46-year-old woman visited our clinic with a 2-month history of right eye pain and migraine, as well as a 3-day history of acute horizontal diplopia. She had previously been diagnosed with Crohn's disease and was taking immunosuppressive drugs. In the eye movement test, esotropia and an abduction limitation of -3.0 in the right eye were observed on the Krimsky test. There were no specific findings in anterior segment and fundus examinations. Orbital magnetic resonance imaging showed multiple extraocular muscle enhancement in the right eye and multiple extraocular muscle hypertrophy in the left eye. The patient was diagnosed with binocular multiple orbital myositis and right Tolosa-Hunt syndrome; she was treated with high-dose steroids for 3 days followed by lower dose oral medications. During the first week of treatment, the right eye pain disappeared and the right eye abduction limitation showed slight improvement. After 3 months of treatment, the right eye abduction limitation and esotropia completely disappeared. @*Conclusions@#Orbital myositis and Tolosa-Hunt syndrome are idiopathic, nonspecific chronic granulomatous diseases with painful ophthalmoplegia. We describe a rare case in which the two diseases appear together.

Presumed Latent Tuberculosis-related Intermediate Uveitis Manifesting as Recurrent Vitreous Hemorrhage

Purpose@#We report a case of recurrent vitreous hemorrhage in a patient with presumed latent tuberculosis-related intermediate uveitis, and we review the literature.Case summary: A 58-year-old male visited our clinic complaining of ocular pain, conjunctival hyperemia, decreased vision, and uncontrolled intraocular pressure (IOP) in the left eye. The best-corrected visual acuity (BCVA) was 0.4 and the IOP of the left eye was 34 mmHg. Slit lamp examination revealed conjunctival hyperemia, corneal edema, and inflammatory cells in the anterior chamber and anterior vitreous; fundus examination revealed mild vitreous opacity attributable to vitritis. The high IOP and the intraocular inflammation were treated with antiglaucoma agents and corticosteroids under the impression of chronic anterior uveitis and uveitic glaucoma. Of the tests performed to identify the cause of the uveitis-related vitreous hemorrhage, the interferon-gamma release assay was positive. A presumptive diagnosis of latent tuberculosis-related uveitis was made after pulmonary tuberculosis was excluded by our respiratory internal medicine department. Isoniazid was administered for 9 months. The vitreous hemorrhage recurred 1 month after antituberculosis therapy commenced but, at 2 months, all of the hemorrhage was absorbed and the BCVA improved to 1.0 without further recurrence. @*Conclusions@#Intraocular tuberculosis can present with various clinical manifestations. If tuberculosis-related uveitis is presumed, tests for latent and manifest tuberculosis should be scheduled to allow of early diagnosis and immediate antituberculosis therapy.

Clinical Features and Course of Acquired Third Cranial Nerve Palsy

Purpose@#The purpose of our study was to investigate the clinical features and course of acquired third cranial nerve (CN3) palsy. @*Methods@#We retrospectively reviewed the medical records of 40 consecutive patients who underwent at least 3 months of follow-up clinical evaluation from March 2016 to December 2019 who were admitted to the ophthalmologic department or referred from other departments of Samsung Changwon Hospital and diagnosed with acquired CN3 palsy. @*Results@#The average age of patients with acquired CN3 palsy was about 64.6 ± 15.9 years and the mean follow-up period was 4.4 ± 8.4 months. Microvasculopathy (twelve patients, 30.0%) was the most common etiology followed by brain vascular lesions (eight patients, 20.0%), and tumors (eight patients, 20.0%). The complete recovery rate was 67.5% and non-isolated CN3 palsy was recorded in 30.0% cases of which six cranial nerve palsy (in eight patients, 66.7%) was the most common. Microvasculopathy (42.9%) and tumors (66.7%) were the most common features in the recovery and persistent groups, respectively. Extraocular movement limitation at the first visit was smaller in the recovery group (−2.4 ± 1.1) than in the persistent group (−3.2 ± 0.6); the difference was statistically significant (p = 0.039). Pupil involvement was found in one (8.3%) patient from the microvascular group and in eight (61.5%) patients from the compressive lesion group. @*Conclusions@#The microvascular group or those with a low degree of extraocular movement limitation at the first visit had the highest recovery rate in acquired CN3 palsy. Although compressive lesions showed high pupillary involvement, imaging study should be considered for confirmation rather than attempting to discriminate the causative disease based solely on pupil involvement.

Metastatic Small Cell Neuroendocrine Carcinoma to the Orbit Manifesting as Total Ophthalmoplegia

PURPOSE@#To report a case of primary ureteral small cell neuroendocrine carcinoma metastasis in the left orbital wall, with a review of the literature.CASE SUMMARY: A 79-year-old male visited our clinic with a 10 day history of ocular pain, ptosis, and ophthalmoplegia in the left eye. He had been diagnosed with diabetes mellitus and was being treated for prostate adenocarcinoma. The corrected visual acuity was 0.8 in the right eye and 0.5 in the left eye. An extraocular movement test showed total ophthalmoplegia, mild exophthalmos, and ptosis in the left eye. Orbital computed tomography (CT) and magnetic resonance imaging showed an irregular mass-like enhancement in the superolateral orbital wall of the left eye, suggesting infectious and inflammatory orbital disease. After antibiotic treatment, high dose systemic steroids were administered. However, there was no improvement and the orbital CT was again performed, with no changes. A surgical biopsy for differentiating orbital tumors was performed and diagnosed as a metastatic orbital small cell neuroendocrine carcinoma. Using positron emission tomography, he was later diagnosed with a metastatic orbital small cell neuroendocrine carcinoma with multiple metastases.@*CONCLUSIONS@#When the patient has a mass-like lesion on imaging with ocular pain, ophthalmoplegia, or ptosis, a surgical biopsy should be performed to make a diagnosis and determine the optimal management.

Congenital Ptosis Repair by Preserved Fascia Lata with Direct Tarsal and Frontalis Fixation

PURPOSE: To investigate the outcome of frontalis suspension surgery congenital blepharoptosis with poor levator palpebral muscle function using preserved fascia lata with direct tarsal and frontalis fixation method. METHODS: Twelve congenital ptosis patients (fourteen eyes) who underwent frontalis suspension using preserved fascia lata with direct tarsal and frontalis fixation method between July 1999 and June 2002 with the mean follow-up time of 54.8 months (31 months~78 months) included. And the postoperative results were obtained from medical records retrospectively. RESULTS: The desired lid height was achieved in eight out of twelve patients (71.4%) after surgery. In four patients (4 eyes) (28.6%), adjustment was required due to under-correction within one month postoperatively. At a mean follow-up period of 54.8 months, all twelve patients had good final results with no postoperative complications. CONCLUSIONS: Frontalis suspension using preserved fascia lata with direct tarsal and frontalis fixation method provided cosmetically pleasing results with a low rate of ptosis recurrence and complication related to procedures. This method using preserved facia lata could be considered as alternative to the use of autogenous facia lata for the repair of ptosis.

A Case of Klippel-Feil Syndrome combined with Duane Retraction Syndrome: Incomplete Form of Wildervanck Syndrome

PURPOSE: Klippel-Feil syndrome is defined as the congenital fusion of two or more cervical vertebrae. The clinical features are low posterior hair line, short neck, and limitation of the movement of the head and neck. Wildervanck syndrome, also known as cervicooculoacoustic syndrome, is a rare genetic disorder that primarily affects females. The disorder is characterized by Klippel-Feil syndrome, Duane syndrome and hearing impairment at birth, although one of these symptoms may be lacking. This report describes a case of Klippel-Feil syndrome combined with Duane retraction syndrome, which can be defined as an incomplete form of Wildervanck syndrome. METHODS: A 15-year-old girl with congenitally fused cervical vertebrae at two levels, C2-C4 vertebrae and, C5-C7 vertebrae, was diagnosed as Klippel-Feil syndrome. Ophthalmologic evaluation was needed due to abnormality in ocular motility. RESULTS: Ophthalmologic examination revealed a visual acuity of 0.9 without correction in both eyes. Slit-lamp and fundus examination were normal. Ocular motility examination showed 14 prism diopters right esotropia in primary gaze, limited abduction, globe retraction, and narrowing of the palpebral fissure on adduction of the right eye.

Transcavernous Approach for Invasive Pituitary Adenoma

OBJECTIVE: Surgical management of invasive pituitary tumor is challengeable with conventional transsphenoidal approach(TSA) or pterional intradural approach alone. Gross total resection of pituitary adenoma influences its prognosis favorably, so transcavernous approach(TCA) is essential in invasive pituitary tumor. This study is performed to evaluate and analyze the surgical results of TCA in cases of invasive pituitary adenoma. METHODS: From November 1995 to May 2002, nine cases of invasive pituitary adenoma were treated. The authors reviewed medical records and radiological findings. Pterional transzygomatic or orbitozygomatic transcavernous approach was selected for tumors extended below or above the third ventricle floor respectively and intradural removal of tumor with suprasellar extension was combined. Surgical results including hormonal function, recurrence, completeness of tumor resection, and postoperative complications were evaluated and analyzed. RESULTS: Eight patients were treated with TSA followed by TCA and one with TCA alone. Total resection was achieved in seven cases, subtotal resection in one, and partial resection in one. Postoperative complications included temporary third nerve palsy in four cases and facial paresthesia in two. There was no recurrence during follow-up period. CONCLUSION: Transcavernous approach alone or combined with TSA is essential surgical procedure for total removal of invasive pituitary adenomas with acceptable morbidities.

Three Cases of Waardenburg Syndrome Type 2 in a Korean Family

Waardenburg syndrome (WS) is a rare, autosomal dominant disorder characterized by sensorineural hearing loss, pigmentary disturbances of the skin, hair, and iris, and other developmental defects such as lateral displacement of both medial canthi and lacrimal puncta called dystopia canthorum. While mutations of the PAX3 (paired box) gene have been identified in about 99% of WS type 1 cases, WS type 2 is a heterogeneous group, with about 15% of cases caused by mutations in microphthalmia associated transcription factor (MITF). We have experienced three cases of typical WS type 2 in a Korean family, for whom full ocular examination and genetic studies were performed. The genetic studies revealed no mutation in either PAX3 or MITF genes. The genetic basis, as yet unknown for most cases of WS type 2, might be found with further investigation.

The effects of surface contamination by hemostatic agents on the shear bond strength of compomer / 대한치과보존학회지

One of the latest concepts in bonding are "total etch", in which both enamel and dentin are etched with an acid to remove the smear layers, and "wet dentin" in which the dentin is not dry but left moist before application of the bonding primer. Ideally, the application of a bonding agent to tooth structure should be insensitive to minor contamination from oral fluids. Clinically, contaminations such as saliva, gingival fluid, blood and handpiece lubricant are often encountered by dentists during cavity preparation. The aim of this study was to evaluate the effect of contamination by hemostatic agents on shear bond strength of compomer restorations. One hundred and ten extracted human maxillary and mandibular molar teeth were collected. The teeth were removed soft tissue remnant and debris and stored in physiologic solution until they were used. Small flat area on dentin of the buccal surface were wet ground serially with 400, 800 and 1200 abrasive papers on automatic polishing machine. The teeth were randomly divided into 11 groups. Each group was conditioned as follows: Group 1: Dentin surface was not etched and not contaminated by hemostatic agents. Group 2: Dentin surface was not etched but was contaminated by Astringedent(R)(Ultradent product Inc., Utah, U.S.A.). Group 3: Dentin surface was not etched but was contaminated by Bosmin(R)(Jeil Pharm, Korea.). Group 4: Dentin surface was not etched but was contaminated by Epri-dent(R)(Epr Industries, NJ, U.S.A.). Group 5: Dentin surface was etched and not contaminated by hemostatic agents. Group 6: Dentin surface was etched and contaminated by Astringedent(R). Group 7: Dentin surface was etched and contaminated by Bosmin(R). Group 8: Dentin surface was etched and contaminated by Epri-dent(R). Group 9: Dentin surface was contaminated by Astringedent(R). The contaminated surface was rinsed by water and dried by compressed air. Group 10: Dentin surface was contaminated by Bosmin(R). The contaminated surface was rinsed by water and dried by compressed air. Group 11: Dentin surface was contaminated by Epri-dent(R). The contaminated surface was rinsed by water and dried by compressed air. After surface conditioning, F2000(R) was applicated on the conditoned dentin surface. The teeth were thermocycled in distilled water at 5degrees C and 55degrees C for 1,000 cycles. The samples were placed on the binder with the bonded compomer-dentin interface parallel to the knife-edge shearing rod of the Universal Testing Machine(Zwick Z020, Zwick Co., Germany) running at a cross head speed of 1.0 mm/min. Group 2 showed significant decrease in shear bond strength compared with group 1 and group 6 showed significant decrease in shear bond strength compared with group 5. There were no significant differences in shear bond strength between group 5 and group 9, 10 and 11.

Detection of black-pigmented bacteria in infected root canals / 대한치과보존학회지

Black-pigmented bacteria have been implicated in the endodontic infections. This group of microorganisms includes Porphyromonas endodontalis, Porphyromonas gingivalis, Prevotella intermedia, and Prevotella nigrescens. The organisms display a wide variety of virulence factors that may be pertinent to acute endodontic infections. The aim of this study was to identify P. endodontalis, P. gingivalis, P. intermedia, and P. nigrescens by using special potency disk test, filter paper spot test, 16S rRNA gene-directed PCR, and API 32A. Microbial samples were collected from root canals of 33 intact teeth with necrotic pulp and/or apical periodontitis. Conventional laboratory methods were used for identification of the strains of black pigmented bacteria. Eighteen of 33 samples were positive for the growth of black-pigmented bacrteria. Five colonies were cultured from each pure cultured colonies from Brucella agar plate. Seventy seven colonies were positive for the growth of black-pigmented bacteria. Thirty three of 77(42.6%) were identifed as P. nigrescens, 10 of 77(12.9%) were P. gingivalis, 6 of 77(7.8%) were P. endodontalis, 10 of 77(12.9%) were P. intermedia. On the contrary the reference strains of P. nigrescens, experimental strains of P. nigrescens was sensitive to kanamycin in special potency disk test. 16S rRNA gene PCR and API test after rapid presumptative identification methods, such as special potency disk test and filter paper spot test, would be accurate detection methods for black-pigemented bacteria.

Transfection of SV 40 Large T Antigen into Corneal Endothelial Cells

The coeneal endothelium is essential for the maintenance of normal corneal hydration, thickness, and transparency. However, corneal endothelial cells are incapable of significant proliferation in vivo. As we age, the density of corneal endothelial (CEN) cells gradually decreases. The goal of our study is to explore the possibility of enhancing the proliferation of corneal endothelial cells by introduction of SV 40 large T antigen, a transforming protein. To this end, introduction of protein into CEN cells was assessed by liposome assisted beta-galactosidase transfection in vivo, ex vivo, and in vivo. In all cases, cells treated with liposome-protein complex have shown dramatic blue stain in beta-galactosidase activity staining. This result convinced us that we could artificially introduce a foreign protein into a cell. To ascertain where SV 40 large T antigen is localized in the cell, purified SV 40 large T antigen was transfected into the cells using liposome and its presence was determined immunohistochemically. We show that the liposome delivered SV 40 large is localized in the nucleus and mitotic figures which may suggest its functional activity.

A Case of Congenital Lipoid Adrenal Hyperplasia

Congenital lipoid adrenal hyperplasia is the rarest type among salt losing types of congenital adrenal hyperplasia. The defect of this disorder is in the cholesterol side chain cleavage enzyme(P450SCC)which converts cholesterol to pregnenolone. W experienced a case of 20,22 desmolse deficiency in a 21-day old phenotypically female who was admitted to our hospital due to lethargy and dark skin pigmentation. The characteristic findings were decreased serum cortisol, aldosterone, testosterone, increased ACTH. The ACTH and hCG stimulation test were performed and there were no response. The sex chromosomal analysis showed made XY. One year later after hormone therapy, growth and development are normal.

Fibrous dysplasia: A Report of Six Cases / 대한정형외과학회잡지

Fibrous Dysplasia of bone is a relatively rare condition characterized by fibrous tissue replacement of skeleton. It may be monostotic (confined to one bone) or polyostotic (situated in many bones). Here, six cases of fibrous dysplasia and, among them, typical three groups classified by Lichtenstein & Jaffe were experienced and treated during past one year. Three cases were monostotic lesion, which is more common, and usually mild and asymptomatic. And another three cases were polyostotic lesion, two of which were not associated with extraskeletal symptoms, and one case was associated with extraskeletal symptoms, so called Albrights disease. These six cases of fibrous dysplasia are reported with a review of the literatures.
