Congenital cystic adenomatoid malformation of the lung is a rare form of congenital cystic disease of the lung and associated with developmental arrest of bronchioles in embryonic life. We report 3 cases of congenital cystic adenomatoid malformation which are classified as type I, II and III according to the morphological classification by Stocker et al. The first case was a 6-year-old female with a mass in the lower lobe of the right lung. The mass was composed of several cysts which were filled with inflammatory exudate and lined by ciliated pseudostratified columnar epithelium (type I + II). The second case was a 4-year-old female with a mass in the middle lobe of the right lung. It was composed of numerous small cysts which were uniform sized and contained inflammatory exudate. These were lined by ciliated columnar and pseudostratified columnar epithelium (type II). The third case was a stillborn female at 27 weeks of gestation. There was generalized edema and severe ascites. The left lower lobe consisted of an ill-defined solid area and small cysts. The solid lesion was composed of bronchiole-sized cysts lined by non-ciliated cuboidal epithelium (type II + III).

Astasia-abasia refers to the inability to stand or walk despite possessing good motor strength and conserved voluntary coordination. Although it is usually regarded as a psychogenic disorder, organic causes have been reported. Herein we describe a patient who presented with alcohol-induced episodic astasia-abasia. Interestingly, SPECT performed during an episode showed hyperperfusion in the dorsal brainstem and subthalamic region. These areas roughly coincide with the mesencephalic locomotor region and subthalamic locomotor region, respectively, and it is conceivable that abnormal neural activity in these areas is related to the symptoms in our patient.

We report a patient with multiple simultaneous embolic infarctions with localized hemorrhagic conversion. A 75-year-old male patient had several silent microbleeds (SMBs) exclusively in the cerebral cortex, and underwent angioplasty and stenting for bilateral carotid stenosis. He subsequently experienced embolic infarctions in the cortex and the striatum: the cortical infarction, where an SMB had been present, showed hemorrhagic conversion, whereas the striatal infarction did not. This case suggests that SMBs are indicators of an underlying hemorrhage-prone state.

Component fixation on the acetabular side is not as much of a problem because of the simpler geometry and loading configuration. It is generally accepted that hemispheric component design is preferable and immediate implant stability can be achieved by using screws or spikes in the porous coated implants. The authors reviewed 130 primary noncemented porouscoated, press fit acetabular component in 110 patients; 84 were AML (Anatomical Medullary Locking) and 46 were HarrisGalante acetabular component. Radiologic analysis at a minimum of 3 years(average 4.5 years) was done with special regards to the vertical and medial migration, screw size and numbers, change of the radiolucent line and its zone with its fate and acetabular cup angles on the acetabular component by the 2 observers. Progressive radiolucent line at the component-bone intersurface were found in 14 cases(11%), frequently located in zone I and zone I & II. No significant vertical, medial migration and change of the acetabular cup angle were found. No screw and spike failure had occurred. No component had to be revised because of loosening. As a whole, in our 3-years experience we report excellent results with porous coated acetabular component although it dose not ensure long-term sucess.

Objectives: To survey daily doses of dopaminergic medications and to draw a posteriori equation of the dose in relation to the various clinical variables in Korean patients with Parkinson disease. Methods: A multi-center cross-sectional survey was conducted over a defi ned period. Information on patient demographics and clinical features including age at Parkinson disease onset, disease duration, treatment duration and Hoehn and Yahr stage, and daily doses of anti-parkinsonian drugs was obtained from the patients’ medical records. Results: A total of 1,762 patients with Parkinson disease were recruited from 6 referral centers. The mean L-dopa equivalent daily dose (LEDD) in the whole population was 608.9 mg/day, which tended to increase linearly depending on the duration of disease and Hoehn and Yahr stage. LEDD was also signifi cantly affected by age and gender. We performed multiple linear regression analyses and devised a posteriori equation of LEDD with clinical variables. Conclusions: This survey provides systematic data for mean LEDD in Korean Parkinson disease patients. In spite of profound individual variations in LEDD, our linear regression model provides an insight about the relationship between daily doses of dopaminergic medications and various clinical features of Parkinson disease.

To attempt a rigorous definition of the structure of the accessory spleen (AS) in the Chinese hamster, we examined twenty-one animals, and found AS in 5 animals (23.8%), which were over 7-month-old. The AS had no connection with the main spleen and was seen as a dark red oval organ (0.7 mm x 1.5 mm), which was embedded in the adipose tissue near the tail of the pancreas. It was demarcated from the adipose tissue and some pancreatic tissue. The organ was encapsulated by thin collagenous connective tissue and smooth muscle fibers, and contained lymphatic nodules, reticular fibers, nodular central arterioles, macrophages and megakaryocytes. Notably the incidence of AS appeared to increase with age in the Chinese hamsters.
