BACKGROUND: The aim of this study was to answer the following two questions: 1) Do the radiological parameters of dysplasia have significant correlations between themselves or with the parameters of the proximal femoral deformity and vice versa? 2) Do the physical parameters have a significant correlation with the radiological parameters of hip dysplasia and proximal femoral deformity? METHODS: Four hundred and twenty eight consecutive patients with no clinical evidence of hip osteoarthritis and who underwent pelvic radiography in the supine position for hip contusion or a routine health check were analyzed for the relationships between the center-edge (CE) angle, acetabular depth, acetabular angle, the head-neck ratio and the neck-shaft angle as well as the relationships of the above-mentioned variables with age, gender, body height and the body mass index. RESULTS: The CE angle, acetabular depth and acetabular angle showed a strong correlation with each other. The neck-shaft angle and the head-neck ratio showed no correlation with each other or with the CE angle, acetabular depth and acetabular angle. Age was positively associated with the CE angle, and inversely associated with the acetabular depth or acetabular angle. Male gender was significantly associated with the increased neck-shaft angle, and inversely associated with the head-neck ratio. CONCLUSIONS: The radiological parameters of hip dysplasia are all strongly, if not perfectly, inter-correlated. Age was associated with the radiological parameters of hip dysplasia whereas gender was associated with the radiological parameters of a proximal femoral deformity.

Although myocardial bridge is not thought to have any hemodynamic significance in most cases, some have suggested that when it produces severe systolic narrowing, ischemia or infarction may result. Myocardial bridge in adults with hypertrophic cardiomyopathy may be associated with a higher incidence of sudden death, myocardial wall-motion abnormalities, and perfusion defects on thallium-201 scintigraphy. When myocardial bridge is associated with left ventricular hypertrophy, it is known to affect longer segment and cause more severe compression during systole. We report a case of hypertrophic cardiomyopathy with myocardial bridge at the middle part of the left anterior descending coronary artery, who also showed reversible perfusion defect on the thallium scan at the same coronary territory.

Subperiosteal abscess of the mastoid region and Bezold's abscesses have become very rare since introduction of antibiotics. Subpriosteal abscess is usually seen in children who have acute mastoiditis. Its occurrence in adults or in associated with chronic otitis media is even more unusual. Bezold's abscess, a complication of acute otitis media in adult who has well pneumatized air cells in the tip of the mastoid, is also rarely seen in the current era of antibiotics. This paper reports a case of postauricular subperiosteal and Bezold's abscess complicating chronic suppurative otitis media with cholesteatoma in a 37-year old woman with review of literatures.

BACKGROUND AND OBJECTIVES: Recently, canal down mastoidectomy tends to be more frequently selected for complete eradication of the lesion and prevention of recurrence. Therefore, the problems attendant to the open mastoid continue to be of concern. Although various techniques have been used to solve the cavity problems, no single procedure has yet been devised that entirely accomplished this purpose. We evaluated the effects of partial mastoid obliteration using inferior based musculoperiosteal flap and autogenous conchal cartilage chips. MATERIALS AND METHODS: Twenty four cases were performed with mastoid obliteration using inferior based musculoperiosteal flap and autogenous conchal cartilage chips obtained from meatoplasty. There were 11 cases for control which were performed with canal down mastoidectomy without obliteration. We compared these two groups in the duration of epithelialization, accumulation of debris, presence or absence of drainage, shape of remodeled canal and caloric response and evaluated survival or atrophy of flap and absorption of cartilage chips. RESULTS: Obliteration group showed more rapid healing and epithelialization and less accumulated epithelial debris. Atrophy of flap or absorption of cartilage was not observed. There was no draining ear but vertigo with nystagmus on caloric stimulation developed in both groups. CONCLUSION: This partial mastoid obliteration technique used easy and quick application instead of complete restoration of canal wall, and it may be also valuable in providing rapid epithelialization and reducing mastoid bowl volume with relatively round canal shape. Furthermore, epitympanic obliteration using cartilage chips may be an effective method to prevent formation of attic retraction pocket.

The most common cause of orbital in/fection is a sinusitis, and if this orbital complication is not provided with appropriate and intensive treatments, serious status such as visual loss or life-threatening may occur. Osteomyelitis rarely results from sinusitis, and in cases where it happens, the frontal sinus is the most frequently involved site. However, zygomatic osteomyelitis has not been reported so far. We present a case of maxillary sinusitis which was initiated by oroantral fistula, and developed to preseptal and postseptal abscess, penetrating into the orbital septum. The case was complicated by zygomatic osteomyelitis. This case was successfully treated by draining pus by endonasal endoscopic sinus surgery, infraorbital incision, and was followed by antibiotic therapy for about 8 weeks.

PURPOSE: To evaluate the histopathological changes of anterior capsule and lens epithelial cells in various types of cataract. METHODS: Patients scheduled for cataract surgery of phacoemulsification with intraocular lens implantation were enrolled in this study. Anterior capsule tissues sized 5 mm were obtained at the time of continuous curvilinear capsulorhexis during surgery. Histological examination of the obtained tissue was performed by transmission electron microscope. RESULTS: Nuclear cataract showed a uniform cuboidal monolayer of epithelial cells firmly attached to the anterior capsule. But, the mitochondria, Golgi apparatus, and endoplasmic reticulum were damaged and replaced with vacuoles. Anterior subcapsular cataract showed multilayers of epithelial cells with irregular intracellular structures. Epithelial cells of mature cataract were severely damaged and detached from the anterior capsule, accompanied by expansion of intra-cellular space and a large amount of vacuoles. Epithelial cells were irregular and severely damaged, and intracellular structures were hardly observed in traumatic cataract. Deposition of pseudoexfoliation materials on the anterior capsule was observed in pseudoexfoliation cataract. CONCLUSIONS: Changes in epithelial cells caused by fluid accumulation and electrolyte imbalance in the lens attributes more to cataract formation than do changes the in lens capsule.

We report a patient who was diagnosed as subacute combined degeneration (SCD) with elevated homocysteine and methylmalonic acid levels in the situation of a spurious elevation of the vitamin B12 concentration. A false-positive elevation of the vitamin B12 level could lead to a delayed diagnosis and cause irreversible changes in the nervous systems. We therefore suggest that the homocysteine and methylmalonic acid levels should be checked in patients with a normal or elevated vitamin B12 level for whom there is a high clinical suspicion for vitamin B12 deficiency, as a further evaluation for SCD.
