We report the clinical course of photodynamic therapy (PDT) in a patient with drusenoid pigment epithelium detachment (PED). A patient with drusenoid PED underwent PDT follow-up was carried out at one week, one month, three months, six months and one year after treatment. Fundus exam, optical coherence tomography (OCT) and fluorescein angiography were performed. After the PDT, drusen and PED were gradually diminished over one year. However, pure serous PED eventually developed at the same location of the drusenoid PED. The results of the PDT, on drusenoid PED, were initially effective, but not completely successful. Therefore, PDT may be considered as an alternative treatment option for drusenoid PED.

BACKGROUND: Portable devices for measuring peak expiratory flow(PEF) are now of proved value in the diagnosis and management of asthma and many lightweight PEF meters have become available. However, it is necessary to determine whether peak expiratory flow rate(PEFR) measurements measured with peak flowmeters is accurate and reproducible for clinical application. The aim of the present study is to define accuracy, agreement, and precision of mini-Wright peak flow meter(MPFM) against standard pneumotachygraph. METHODS: The lung function tests by standard pneumotachygraph and PEFR measurement by MPFM were performed in a random order for 2 hours in 22 normal and 17 asthmatic subjects and also were performed for 3 successive days in 22 normals. RESULTS: The PEFR measured with MPFM was significantly related to the PEFR and FEV1 measured with standard pneumotachygraph in normal and asthmatics(for PEFR, r=0.92 p<0.001; for FEV1, r=0.78 ; p<0.001). The accuracy of MPFM was within 10%(limits of accuracy recommeded by NAEP) in all the subjects or 22 normal, mean difference from standard pneumotachygraph being I 6.5L/min(percentage of difference being 2.90%) or 1 0.6L/min(percentage of difference being 1.75%), respectively. According to the method proposed by Bland and Altman, the 95% limits of the distribution of differences between MPFM and standard pneumotachygraph after correction of PEFR using our regression equation were +38.2 and -71.5L/min in all the subjects or -20.49~ + 9.49L/min in 22 normal and was similar to the intraindividual agreements for 3 successive days in normal. There was no statistically significant difference of PEFR measured with MPFM and standard pneumotachygraph among three days(p>0.05) and the coefficient of variation(2.4 1.2%) of PEFR measured with MPFM was significantly lower than that( 5.2 3.5%) with standard pneurnotachygraph in normal (p<0.05). CONCLUSION: This results suggest that the MPFM was as accurate and reproducible as standard pneumotachygraph for monitoring of PEFR in the asthmatic subjects.

BACKGROUND: Improved diagnostic and therapeutic strategies for infective for infective endocarditis such as proposed diagnostic criteria, Duke criteria and echocardiography resulted to increased life-spans of patients. METHODS: Retrospective analysis of medical records including medical history, laboratory data such as echocardiographic data and blood culture, and clinical outcomes was done for 106 patients with clinical diagnosis of infective endocarditis at Seoul National University Hospital from January 1990 to May 2000. Then we analysed differences of clinical features between elderly patients aged > or =60-years and the adult patients aged <60-years with infective endocarditis. RESULTS: The elderly patients >or=60-year are cases of 14%(15/106) and the mean ages are 67+/-8 years in elderly patient, 38+/-12 years in the adults patients respectively. Valvular heart disease was the most common predisposing heart disease with 9 cases(40%) followed by prosthetic valve endocarditis 2 cases (13%) in elderly patients, and there was no significant difference of frequencies with adult patients (valvular heart diseases, 33%; prosthetic valvular heart diseases, 25%). Although culture positive rates were not different with two groups: 47%(7/15) in elderly patients and 45%(41/91) in adult patients, the most common pathogen was staphylococcal species in elderly patients(27%, 4/15) but streptococcus species, in the adult patients(25%, 26/106, p<0.05). The frequencies of embolic complication were not different between two groups(20%, 3/15 vs 22%, 20/91: Elderly vs adult, respectively), but congestive heart failure was more developed in elderly patients, 33%(5/15) than in adult patients, 10%(9/91, p<0.05). Surgical intervention was more required in the elderly(47%, 7/15) than in adult patients(22%, 20/91, p<0.05). Out of 106 patients, 11 died and the overall mortality was 10.4%(11/106). In-hospital death was more common in the elderly than in adult patients: 4 cases(27%) vs 8%(7/91), p<0.05. Determinants of in-hospital death were patients with 60 years of age and older, Staphylococcus aureus endocarditis, and the presence of congestive heart failure(p<0.05) in univariate analysis. CONCLUSION: Infective endocarditis in elderly patients(age> or =60) had more poor outcomes than adult patients(age<60) such as the development of congestive heart failure, the need of surgical intervention, and the high mortality rate.

This statistical analysis of 4,709 legal autopsies performed in Korea in 2012 was conducted to obtain primary data about and related variables. The analysis revealed the following: 1. Of the total number of deaths, men accounted for and women, 26.8%. Evidently, the number of deaths among men was more than twice that among women. 2. With respect to mode of death, 54.8% were recorded as unnatural deaths, 39.2% were natural deaths, and 6.0% had unknown causes. Of the 2,581 unnatural deaths, 44.8% were accidental deaths; 27.2%, suicidal; 17.5%, homicidal; and 10.3%, undetermined. 3. Of the total number of unnatural deaths, 43.0% were trauma-related deaths, for which falling down was the leading cause, accounting for 33.5% cases. Asphyxiation was accounted for 17.2%, among which the predominant cause was hanging (55.3%). Moreover, 12.5% of deaths were due to drowning; 11.5%, poisoning; 11.2%, thermal injuries; 2.7%, complications in medical procedures; and 0.3%, electrocution, starvation, or neglect. 4. Among 1,847 natural deaths, heart diseases accounted for 50.2% and vascular diseases accounted for 16.7%. 5. There were 207 cases of deaths among children under the age of 10, of which 94 were unnatural and 49 were homicidal deaths. Of all cases, 9.2% had an unknown cause of death, and of these 67.6%, were putrefied or skeletonized bodies.

A 44-year-old man was cutting an outer plate of a ship, at a depth of 25 m below sea level. Following a sudden explosion, he was discovered unconscious and was carried to the surface by other divers. There was no evidence of vital signs upon arrival at the hospital. Postmortem computed tomography, which was performed prior to autopsy, revealed massive pneumocephalus in the brain, pneumohemothorax, diffuse lung contusions with multiple traumatic lung cysts, air-fluid level in the cardiac chamber of the chest, and pneumoperitoneum in the abdomen. Postmortem external examination showed a circular abrasion on the jaw, diffuse subcutaneous emphysema, and contusion in the right upper arm. An internal examination revealed intravascular air bubbles in all four chambers of the heart, and diffuse pulmonary trauma including contusion, laceration, and multiple traumatic cysts. Blast injury to the chest, and air embolism due to the underwater explosion were established as the underlying cause of death.

A 69-year-old man was admitted to the hospital because of flu-like symptoms and fatigue for 2 weeks. Computed tomography revealed ground glass opacity and consolidation in both the lungs as well as pleural effusion. The patient was diagnosed with pneumonia and was hospitalized. At the time of hospitalization, he complained of shortness of breath and coughed-up blood-tinged sputum. Two days after admission, he died suddenly. An autopsy was performed; cardiomegaly was noted, and further examination revealed that the aortic valve had been destroyed by multiple, irregular vegetations. Herein, we report an autopsy case of infective endocarditis with a review of the relevant literatures.
