The prevalence of aneurysm formation in adults with Moyamoya disease (MMD) is higher than that in the general population. The treatment strategy is often individualized based on the patient’s disease characteristics. A 22-year-old man was diagnosed with MMD after presenting a small thalamic intracerebral and subarachnoid hemorrhage in the quadrigeminal cistern. Cerebral angiography revealed a small aneurysm (2.42 mm) in the left anterior choroidal artery. Since the hemodynamics in the left hemisphere was compromised, an indirect bypass surgery was performed. The patient’s condition deteriorated postoperatively because of poor perfusion of the internal carotid artery, and massive hydration was required. During neurocritical care, the aneurysm increased in size (5.33 mm). An observation strategy was adopted because of the distal aneurysmal location and the high risk involved. Subsequently, the patient recovered, and newly developed collateral flow appeared from the external carotid artery. Additionally, a dramatic size reduction of the aneurysm (1.51 mm) was noticed. Our case suggests that MMD-related dissecting aneurysms on a distal cerebral artery, which present a high risk of embolization, could be managed by indirectly reducing the hemodynamic burden. Massive hydration in such cases should be avoided or balanced to avoid the risk of rapid growth and aneurysm rupture.

BACKGROUND/AIMS: Colonic diverticulitis is an uncommon disease in young patients. However, the frequency appears to have increased in Korea among young patients. The purpose of this study was to determine the diagnosis, treatment and clinical course of young patients with diverticulitis of the colon. METHODS: The hospital records of 70 patients with diverticulitis between July 1997 and April 2006 from the Eulji university hospital were reviewed. We analyzed the clinical course and outcomes of patients according to age. RESULTS: In the 36 patients below the age of 40, the male to female ratio was 2:1. Thirty four young patients had right uncomplicated colonic diverticulitis. Twenty four young patients treated with antibiotics did not require surgery or develop complications. CONCLUSION: The majority of young patients with diverticulitis were in their fourth decade of life and it was predominantly seen in males. Diverticulitis in young patients at our hospital did not appear to take a more aggressive clinical course than it did in older patients. Bowel rest and antibiotic treatment were safe and effective treatments for acute uncomplicated colonic diverticulitis in young patients.

PURPOSE: To evaluate clinical findings in phlyctenular keratoconjunctivitis patients and assess the function and morphology of Meibomian glands using an interferometer (LipiView®, TearScience, Morrisville, NC, USA) in such patients.METHODS: This retrospective study included 19 eyes of 13 patients diagnosed with phlyctenular keratoconjunctivitis. The lipid layer thickness (LLT) and meibograph of each eye was quantified by tear interferometry. Tear film break-up time (TBUT) and corneal staining score were measured. Meibomian gland morphology (lid margin vascularity, plugging of gland orifices, lid margin irregularity, lid margin thickening, and partial glands) was evaluated based on anterior photographs and meibographs.RESULTS: The mean age was 21.3 years (8–44 years). Mean BUT and Oxford corneal staining scores were 2.6 ± 1.2 seconds and 1.9 ± 0.8, respectively. Abnormal findings of the Meibomian glands were observed in all patients. The mean LLT was 79.6 ± 27.4 µm and the incomplete eye blinking frequency was 3.8 ± 5.9 during 20 seconds. The graphs of the tear lipid layer showed various patterns such as flat, up-hill, down-hill, and mixed.CONCLUSIONS: Meibomian gland dysfunctions and changes in the tear film lipid layer were noted in patients with phlyctenular keratoconjunctivitis. These factors are to be considered for the treatment of phlyctenular keratoconjunctivitis in young patients under 10 years of age.

Objectives:
The purpose of this manuscript was to propose the policy and perspectives of prevention and management for hypertension and diabetes in Korea.
Methods:
Authors reviewed the chronic disease prevention and management projects and models were executed in Korea until now, and analyzed and evaluated their performances.
Results:
In the circumstances of Korea, the following several requisites should be improved ; Specific Korean strategy for development and pursuing of national level policy agenda for chronic disease management must be established. There are a need to establish several means of supplementing the weaknesses of the current chronic disease management policies and programs. Firstly, development and distribution of contents of guidelines on the systematic project execution regime (regarding systematization of local community, subjects and contents of the projects) with guarantee for the quality of chronic disease prevention and management are necessary. Secondly, there is a need for development of information system that can lead the chronic disease management programs currently being implemented. Thirdly, there is urgent need to develop resources such as cultivation of manpower and facilities for provision of education and consultation for the patients and holders of risk factors of chronic disease. Fourthly, there is a need for means of securing management system and financial resources for operation of policies and programs.
Conclusions
The results can be able to use as a road map, models, and direction and strategies of policies for chronic disease prevention and management of Korea.

Background:
Aging leads to sarcopenia, which is characterized by reduced muscle mass and strength. Many factors, including altered muscle protein turnover, diminished neuromuscular function, hormonal changes, systemic inflammation, and the structure and composition of muscle fibers, play a crucial role in age-related muscle decline. This study explored differences in muscle fiber types contributing to overall muscle function decline in aging, focusing on individuals with hip fractures from falls.
Methods:
A pilot study at Chungnam National University Hospital collected muscle biopsies from hip fracture patients aged 20 to 80 undergoing surgical treatment. Muscle biopsies from the vastus lateralis and gluteus maximus were obtained during hip arthroplasty or internal fixation. Handgrip strength, calf and thigh circumference, and bone mineral density were evaluated in individuals with hip fractures from falls. We analyzed the relationships between each clinical characteristic and muscle fiber type.
Results:
In total, 26 participants (mean age 67.9 years, 69.2% male) were included in this study. The prevalence of sarcopenia was 53.8%, and that of femoral and lumbar osteoporosis was 19.2% and 11.5%, respectively. Vastus lateralis analysis revealed an age-related decrease in type IIx fibers, a higher proportion of type IIa fibers in women, and an association between handgrip strength and type IIx fibers in men. The gluteus maximus showed no significant correlations with clinical parameters.
Conclusion
This study identified complex associations between age, sex, handgrip strength, and muscle fiber composition in hip fracture patients, offering insights crucial for targeted interventions combating age-related muscle decline and improving musculoskeletal health.

BACKGROUND: Pathologic diagnosis of central nervous system (CNS) neoplasms is made by comparing light microscopic, immunohistochemical, and molecular cytogenetic findings with clinicoradiologic observations. Intraoperative frozen cytology smears can improve the diagnostic accuracy for CNS neoplasms. Here, we evaluate the diagnostic value of cytology in frozen diagnoses of CNS neoplasms. METHODS: Cases were selected from patients undergoing both frozen cytology and frozen sections. Diagnostic accuracy was evaluated. RESULTS: Four hundred and fifty-four cases were included in this retrospective single-center review study covering a span of 10 years. Five discrepant cases (1.1%) were found after excluding 53 deferred cases (31 cases of tentative diagnosis, 22 cases of inadequate frozen sampling). A total of 346 cases of complete concordance and 50 cases of partial concordance were classified as not discordant cases in the present study. Diagnostic accuracy of intraoperative frozen diagnosis was 87.2%, and the accuracy was 98.8% after excluding deferred cases. Discrepancies between frozen and permanent diagnoses (n = 5, 1.1%) were found in cases of nonrepresentative sampling (n = 2) and misinterpretation (n = 3). High concordance was observed more frequently in meningeal tumors (97/98, 99%), metastatic brain tumors (51/52, 98.1%), pituitary adenomas (86/89, 96.6%), schwannomas (45/47, 95.8%), high-grade astrocytic tumors (47/58, 81%), low grade astrocytic tumors (10/13, 76.9%), non-neoplastic lesions (23/36, 63.9%), in decreasing frequency. CONCLUSIONS: Using intraoperative cytology and frozen sections of CNS tumors is a highly accurate diagnostic ancillary method, providing subtyping of CNS neoplasms, especially in frequently encountered entities.
