Asthma is one kind of chronic respiratory tract inflammatory disease.Recently,it has been discovered that the small airway also participates in asthmatic pathogenesis.The small airway which diameter is less than 2 mm is one of the smallest regions in the lung.Its function may be affected by the small airway disease and related with the airway hyperresponsiveness.Some structural changes in the small airway is the latent reason which aggravates asthma.The change of small airway function in the mild asthma can cause the change of airway hyperresponsiveness.So it is considered that the small airway function is one of the methods to monitor the asthmatic situation.

To study the related substances in nicergoline, electrospray positive ionization high resolution TOF/MS was used for the determination of the accurate mass and elemental composition of the related substances. Triple quadrupoles tandem MS/MS was employed for the determination of the fragmentations of the parent ions. 16 related substances were detected and identified to be eight synthetic by-products and eight degradation products, by using impurity references matching, product mass spectra fragmentations elucidation, and verified further according to synthetic processes and stress testing results. The results obtained are valuable for nicergoline manufacturing process control and quality assurance.

Trichilemmal carcinoma is a rare malignant neoplasm of the hair follicle, which is derived from or differentiates towards cells of the outer root sheath. We report a case of trichilemmal carcinoma in an 83-year-old female patient. She presented with a tender dome-shaped crusted papule showing a feature of cutaneous horn on the forehead, which was first detected 6 months before. nstopathologically, lobular patterned tumor cells with peripheral palisade of basaloid cells, nuclear atypia, and clear or pale, PAS-positive, diastase-sensitive cytoplasm were observed beneath the marked hyperkeratosis. After the diagnosis, total excision was done. The patient has been free of recurrence or metastasis till now.

Objectives:
This study analyzed the decline in quality of life according to age in the chronic disease patient group, quantified it as a quantitative index, and compared it by sex and chronic disease.
Methods:
In the 2017-2019 Korea National Health and Nutrition Examination Survey database, 11,473 adults aged 19 years or older, excluding cancer patients, were analyzed for age-specific changes in the EQ-5D Index by chronic disease. The decline in quality of life according to age in patients with chronic diseases was analyzed by linear regression analysis while controlling for general characteristics. Then, linear regression analysis was performed according to sex.
Results:
In the case of the control group, the quality of life decreased by 0.0004 for every 1-year increase in age(P<0.001). By chronic disease, asthma(β=0.0019, P<0.001), arthritis(β=0.0017, P=0.002), thyroid disease(β=0.0016, P=0.015), dyslipidemia(β=0.0011, P=0.020), and hypertension(β=0.0009, P=0.027) mostly showed a greater decrease in quality of life than the control group. In addition, when divided into two groups by sex, hypertension(β=0.0012, P=0.029), thyroid disease(β=0.0041, P=0.038), and arthritis(β=0.0022, P<0.001) showed a significant decrease in quality of life only in male. Diabetes(β=0.0056, P=0.038), dyslipidemia(β=0.0022, P=0.001) significantly decreased quality of life only in female.
Conclusions
Chronic disease had a negative impact on patients perception of quality of life, and the more severe the pain and activity limitation due to the chronic disease, the more severe it was. It also showed different patterns according to sex. Therefore, it is necessary to allocate more medical resources and provide policy support to prevent chronic diseases, which are serious social problems.

Kaposis sarcoma is a multicentric neoplastic vascular tumor involving the skin or internal organs. We report a case of classic Kaposis sarcoma in a 69-year-old male who had positive serum cytomegalovirus antibodies and disseminated multiple erythematous to purplish colored confluent papules and edema on both lower legs. The histopathological finding showed abnormally proliferated and dilated vessels, vascular spaces, spindle cells, and extravasated erythrocytes. He was treated with radiotherapy, but died due to ventricular tachycardia.

The monoclonal antibody Ki-1(CD30) was first described in 1982 and was reported to react selectively with Reed-Sternberg cells in Hodgkins disease, highly activated B and T cells and large cell lymphomas of both T-and B-cell origin. Lymphomatoid papulosis(LyP) is characterized by recurrent erythematous papules or nodules that undergo spontaneous healing with hyperpigmentation and scarring. Histologically, two major types of LyP can be distinguished: type A is characterized by the presence of variable numbers of Ki-1+ large, atypical lymphocytes with some Reed-Sternberg like cells and type B is characterized by Ki-1- atypical cerebriform mononuclear cells similar to those in mycosis fungoides. We report a case of Ki-1+ lymphomatoid papulosis which was histopathologically recognized as a type B lesion but represented a Ki-1 positive reaction.

Journal of the Korean Surgical Society 1999;57(6):850-857
BACKGROUND: Infantile Hypertrophic Pyloric Stenosis (IHPS) is one of the most common surgical problems of early infancy and one for which an eminently successful surgical treatment has been available since the work of Ramstedt in 1912. A clinical study was begun to access further the accuracy of ultrasonography in identifying hypertrophic pylorus. METHODS: This study is a retrospective clinical analysis of 31 cases of IHPS treated at the Department of Surgery of Pohang St. Mary's Hospital from Jan. 1990 to Dec. 1997. RESULTS: (1) The most prevalent age group was between 3 weeks and 8 weeks in 24 cases (77.4%), and the ratio of males to females was 5.2:1. (2) Among the 31 cases, new born babies were 21 cases (67.7%). (3) In 30 cases (96.8%), the gestational age was between 37 weeks and 42 weeks, and the birth weight was more than 3.5 kg in 21 cases (67.7%). The body weight percentile at admission was lower than the 50 percentile in 31 cases. (4) Among the 31 cases, breast-fed infants were 15 cases (48.4%), milk-fed 13 cases (41.9%), and mixed-fed 3 cases (9.7%). B type blood group was 23 cases (74.2%), and O type was 4 cases (12.9%). (5) In 4 cases (12.9%), an inguinal hernia was noted as an associated anomaly. (6) The onset of symptoms was neonatal (1 week-12 weeks) in all 31 cases, and the duration of the symptoms was between 1 week and 2 weeks in 18 cases (58.1%). (7) Non-bile stained, projectile vomiting was noted in all 31 cases (100.0%), an olive-shaped mass in right upper quadrant of the abdomen was felt in 27 cases (87.1%), and visible peristalsis on the epigastrium was noted in 25 cases (80.6%). (8) On laboratory tests, 17 patients had leukocytosis, and anemia was observed in 2 cases. Hypokalemia was observed in 9 cases (29.0%), hypochloremia in 4 cases (12.9%), and moderate to severe alkalosis (CO2 content > 25 mEq) in 7 cases. (9) Among the 25 cases, for which an the ultrasonographic evaluation was performed, the length of the stenotic canal was from 16 mm to 20 mm in 23 cases (92.0%), and the thickness of the stenotic portion was from 5 mm to 6 mm in 21 cases (84.0%). (10) All 31 cases were surgically treated by using a Fredet-Ramstedt pyloromyotomy, and the mortality was nil. The average hospitalization was 9.4 days. (11) There was 1 case of duodenal perforation and 1 case of intermittent non-projectile vomiting after the operation. CONCLUSIONS: We conclude that early accurate diagnosis, adequate preoperative preparation of the fluid & electrolyte imbalance, immediate surgical correction, and scheduled careful oral feeding are important in treatment of IHPS. Ultrasonographic determination of pyloric muscle length and thickness is the most accurate of the currently available techniques. A Fredet-Ramstedt pyloromyotomy is a safe and successful surgical procedure.
