BACKGROUND: The peak flowmeter is very useful in monitoring of out-patients as well as those in emergency departments because of its convenience and simplicity with low cost. There have been many studies aimed at determining the accuracy and reproducibility of the peak flow meter in normal population. However, there is a paucity of reports regarding its accuracy in patients with chronic obstructive pulmonary disease(COPD) or asthma. The accuracy of the peak expiratory flow(PEF) measured with a mini-Wright peak flowmeter was assessed by a comparison with the results of a mass flow sensor. METHODS: The PEF measurements were performed in 108 patients aged 19-82 years presenting with either a chronic obstructive lung disease or asthma before and after inhaling salbutamol. The PEF measurements from the mini-Wright flowmeter were compared with those obtained by the calibrated mass flow sensor. RESULTS: The average of the readings taken by the mini-Wright meter were 37-39 l/min higher than those taken by the mass flow sensor. The average percentage error of the mini-Wright meter were higher, ranging less than 300 l/min. The mean of the differences between the values obtained using both instruments (the bias)±limits of agreement(±2 SD) were 37.1±90 l/min for the PEF(p<0.001). CONCLUSIONS: The mini-Wright peak flowmeter overestimated the flows in patients with COPD or asthma. It was also found that the accuracy of the mini-Wright peak flowmeter decreased in its mid to low range. The limits of agreement are wide and the difference between the two instruments is signigicant. Therefore, the measurements made between the two types of machines in patients with asthma or COPD cannot be used in terchangeably.

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).

Pathological laughing and crying(PLC) is a condition that is characterized by episodic, brief, contextually inappropriate, uncontrollable outbursts of laughing and/or crying. It can be observed in patients with various neurological disorders. PLC often causes distress in interpersonal functioning and activities for patients and their families. PLC can be recognized easily with proper understanding of the condition and its nature. Also it generally shows good response to various pharmacological treatments. This review aims to encourage the diagnosis and treatment of PLC by providing definition and clinical presentation of PLC, analysis of its pathophysiology and various current treatment options.

BLAST, a basic bioinformatics tool for searching local sequence similarity, has been one of the most widely used bioinformatics programs since its introduction in 1990. Users generally use the web-based NCBI-BLAST program for BLAST analysis. However, users with large sequence data are often faced with a problem of upload size limitation while using the web-based BLAST program. This proves inconvenient as scientists often want to run BLAST on their own data, such as transcriptome or whole genome sequences. To overcome this issue, we developed NBLAST, a graphical user interface-based BLAST program that employs a two-way system, allowing the use of input sequences either as “query” or “target” in the BLAST analysis. NBLAST is also equipped with a dot plot viewer, thus allowing researchers to create custom database for BLAST and run a dot plot similarity analysis within a single program. It is available to access to the NBLAST with http:/bitglobal.comblast.
6.Neuroleptic Malignant Syndrome Complicated with Acute Renal Failure Secondary to Quetiapine: A Case Report.
Journal of the Korean Society of Emergency Medicine 2010;21(2):278-281
Neuroleptic malignant syndrome (NMS) is an idiosyncratic, life-threatening complication of treatment with antipsychotic drugs, and this is characterized by fever, severe muscle rigidity and changes of the autonomic nervous system and mental status changes. We present the case of a 19-year-old woman with neuroleptic malignant syndrome that was complicated with acute renal failure secondary to quetiapine overdose. Emergency physicians should keep in mind the possibility of NMS when evaluating patients who present with fever.

Supernunmerary nipple is a developmental anomaly occuring alon, the course of the embryological milk lines. This entity has receieved little attention in the dermatologic literature and has been confused with a pigmented nevus in some cases. We have experienced two ease of the more unusual form of supern umerary nipple. According to the Kajavas classification, our caes are classified as polithelia pilosa and complete breast with nipple.

A case of papillary eccrine adenoma on the right hand of a 84-year-old woman is reported. The tumor was 1 cm in diameter, occupying the whole thickness of the dermis. Histologically, the tumor was composed of dilated tubules of various sizes with intraluminal papillary projections, and was surrounded by a fibrous stroma. An immunohistochemical study revealed that the proliferating tubules were composed of the outermost layer of alpha-smooth muscle actin-positive and the inner layer of keratin 14-negative cells. This antigen expression pattern was comparable to that of the normal eccrine secretory coil, which indicates that the tumor differentiated toward the secretory coil of an eccrine sweat gland.

10.Neuropsychiatric Aspects of Traumatic Brain Injury: Symptoms and Pharmacotherapy.
Korean Journal of Psychopharmacology 2009;20(6):293-300
Traumatic brain injury (TBI) is well recognized as a disability category with high incidence and prevalence as well as considerable impact on survivors and their families. Neuropsychiatric symptoms such as cognitive deficit, psychosis, depression, mania, anxiety are common after TBI. Treatment of the neuropsychiatric symptoms associated with TBI should result in decreased handicap, improved quality of life, and decreased societal impact. This article discusses the clinical approach to treating patients with neuropsychiatric complications following TBI.
