A 54 year-old woman presented with bilateral fatigable blepharoptosis with diurnal fluctuation and diplopia for 10 days. She had a 3 year history of hypertension and showed symptoms of bilateral ptosis, supranuclear upward gaze palsy, and vertical diplopia with the pupils promptly constricting to light. Bell's phenomenon and vertical oculocephalic responses were intact but an impaired convergence was noted in both eyes. A intramuscular neostigmine test was negative. T1 and T2-wighted MRI of the brain showed a small round high signal intensity lesion in the periaqueductal gray (PAG) region. Therefore, she was diagnosed with a midbrain ptosis due to midbrain hemorrhage. The PAG lesion was suggested as contributing to the fatigable blepharoptosis and supranuclear upward gaze palsy in the patient. We recommend that patients with clinical features of myasthenia limited to the ocular muscles and, having risk factors for cerebrovascular disease, be thoroughly evaluated for intracranial lesions if warranted.

BACKGROUND: Alzhiemeranjx disease (AD) and vascular dementia (VD) are common types of dementia. As a result of the development of new specific agents for AD, and because vascular dementia is a potentially preventable dementia, differentiating these diseases is of great importance. The role of EEG spectral analysis in the differential diagnosis between Alzheimer type and vascular dementia is still controversial. Since there have been few studies concerning the differential diagnosis of dementia by EEG, the present study has focused on this aspect. Usefulness of EEG in differen-tial diagnosis of dementia will be elucidated by clarifying relationship between type of dementia and spectral profile of EEG. METHODS: We analyzed the power spectra taken from 16 derivations and spectral profile was constructed by averaging twenty 2 sec epochs in three study groups (normal controls, AD and VD). Spectral profile was divided into three groups; (I) type A, showing a dominant 6.5-12 Hz peak (ii) type B, lacking a dominant peak in the 6.5-12 Hz (iii) type C, corresponding to a flat, low voltage, spectrum. To elucidate the relationship between spectral profile and other factors including diagnosis, statistical test was done. RESULTS: (1) In AD, type C profile was statistically more prevalent than in VD and type A profile was reversed. (2) In AD, Mini-Mental State Examination (MMSE) score was statistically lower in type C profile. (3) Spectral profile was not associated with age, age of symptom onset, and symptom duration. CONCLUSIONS: This study suggested that spectral profile is a useful tool for the differential diagnosis of dementia (AD and VD) and correlated with the severity of disease in AD.

One hundred seven isolates of Staphylococcus aureus from bovine mastitis were investigated for colony morphology in serum-soft agar (SSA), autoagglutination in salt, and capsular serotype. Capsular polysaccharide (CP) was purified and quantified from the extracts of clinical isolates. Overall, 89 isolates (83.2%) were diffuse in the SSA, without any difference in the proportion of diffuse colony between type 5 and type 8 strains. Some strains exhibited compact colonies in the SSA and expressed CP as determined by an enzyme-linked immunosorbent assay, indicating that compact morphology does not exclude encapsulation. The majority of the strains (11/12) showed autoagglutination in the salt aggregation test. The serotype 336 accounted for 46.7% of the isolates followed by serotype 5 (12.1%) and serotype 8 (12.1%). Particularly, twenty-six (24.3%) isolates reacted with two serotypes; 7 for type 8/336 and 19 for type 5/336. Five isolates (4.7%) were nontypeable with monoclonal antibodies specific for CP serotype 5, 8, or 336. The CP concentration in culture supernatants varied with the serotypes, and the total amount of CP produced by cells grown in a liquid medium was much less than that produced by cells grown on a solid medium. The Western blotting indicated that the CP bands of S. aureus serotype 5 and 8 were ranged in the molecular mass of 58-84 kilodalton (kDa), with additional bands in the region of approximately >or= 48 or Agglutination Tests ; Animals ; Bacterial Vaccines/administration & dosage ; Cattle ; Cattle Diseases/immunology/microbiology ; Female ; Mastitis, Bovine/*microbiology ; Polysaccharides, Bacterial/*classification/isolation & purification ; Serotyping/methods/veterinary ; Staphylococcal Infections/immunology/*veterinary ; Staphylococcus aureus/*classification/*immunology/isolation & purification

Global incidence of neurodegenerative diseases (NDDs) such as Alzheimer’s disease (AD) and Parkinson’s disease (PD) is rapidly increasing, but the diagnosis of these diseases at their early stage is challenging. Therefore, the availability of reproducible and reliable biomarkers to diagnose such diseases is more critical than ever. In addition, biomarkers could be used not only to diagnose diseases but also to monitor the development of disease therapeutics. Urine is an excellent biofluid that can be utilized as a source of biomarker to diagnose not only several renal diseases but also other diseases because of its abundance in invasive sampling. However, urine was conventionally regarded as inappropriate as a source of biomarker for neurodegenerative diseases because it is anatomically distant from the central nervous system (CNS), a major pathologic site of NDD, in comparison to other biofluids such as cerebrospinal fluid (CSF) and plasma. However, recent studies have suggested that urine could be utilized as a source of NDD biomarker if an appropriate marker is predetermined by metabolomic and proteomic approaches in urine and other samples. In this review, we summarize such studies related to NDD.

The present study was conducted in order to investigate the immunologic alterations alongside the numerical changes in peripheral blood lymphocytes(PBL) and their subsets in stomach cancer patients. Lymphocyte surface markers were determined in 85 stomach cancer patients and 49 controls by indirect immunofluorescence technique using monoclonal antibodies. Monoclonal antibodies used were Leu 2a(CD8, suppressor/cytotoxic T cells), Leu 3a(CD4, inducer/helper T cells), Leu 4(CD3, pan T reagent), Leu 11(CD16, natural killer cells) and Leu 12(CD19, B cells). The numbers of PBL, CD3+, CD4+, CD8+, CD16+ and CD19+ cells significantly decreased and the CD4: CD8 value increased in 85 patients with stomach cancer compared to those in controls(p < 0.01). In stage I(n = 17), neither PBL, their subsets nor the CD4: CD8 value were significantly different from those of the controls. In stage II(n = 17), the numbers of PBL, CD3+, CD4+ and CD8+ cells decreased(p < 0.01). In stage III(n = 24) and IV(n = 27), PBL and all subsets measured decreased(p < 0.01). The CD4: CD8 value showed significant increases in stages III and IV(p < 0.01), because the CD8+ cells decreased to a greater extent than did the CD4+ cells. The results demonstrating that the lymphocyte subsets are depressed differentially with the stage suggest that host immunity is impaired with the progression of stomach cancer.

An interdigital pilonidal sinus is considered a rare occupational disease related to individuals with short hair. We describe a case of a 44-year-old man who presented with a tender nodule with a purulent discharge in the fourth interdigital web space of the left foot. The biopsy specimen showed a sinus tract surrounded by keratin and squamous epithelium, and the track contained acute and chronic inflammatory cells. The skin lesion was improved with occlusion of the fistula by using 100% bichloracetic acid. We herein report on a rare case of a interdigital pilonidal sinus in the foot, and this occurred with no relation to the patietn's occupation.

BACKGROUND: Mohs micrographic surgery (MMS) is a specialized type of minimal marginal surgery that offers cure rates superior to other options in the treatment of skin cancer. But only a few reports have been published on the long term outcome of MMS in Korean literatures. OBJECTIVE: Our purpose was to report the clinical findings and recurrence rates of all patients with cutaneous malignancy treated with MMS. METHODS: We retrospectively evaluated 123 patients who had been diagnosed with cutaneous malignant tumors and had been treated with MMS and tumor reconstruction. The main outcome measures were patient demographics, duration of tumor, site, preoperative tumor size, method of reconstruction, and recurrence after MMS. RESULTS: The case series comprised 123 patients (51.2% female and 48.8% male) with a mean age of 65.8 years. Most tumors (78.0%) were on the face and 56.6% of all type of skin tumor were located on the left side. The most common skin tumor was basal cell carcinoma (67.5%). The local flap was the most common method to repair surgical defects (49.6%). Recurrence after MMS was diagnosed in 3 of the 123 patients (2.44%). CONCLUSION: MMS may be a safe and satisfactory method for the treatment of cutaneous malignant tumors and the low recurrence rate with MMS emphasizes the importance of margin controlled excision.
