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.

In Korea, children aged 5 to 11 have been vaccinated against coronavirus disease 2019 (COVID-19) from March 2022. Due to this age group not being at a high risk of developing severe COVID-19 symptoms, each major country has different, circumstance dependent, immunization policies for children. In this review, the COVID-19 vaccination policies for 5–11 years old children in major countries were reviewed and considerations were presented for Korea, where children 5–11 years old are starting to get vaccinated against COVID-19.

Intravenous pyogenic granuloma (IVPG) is a form of pyogenic granuloma (PG) in which the capillary proliferation is confined entirely within the lumen of a vein. It occurs typically in the neck and upper extremities. Histologically, this benign lesion is similar to PG of other localizations and is characterized by a lobular proliferation of capillaries growing in a sparsely cellular, edematous collagenous stroma. We report a case of IVPG developing in the palm, an unusual site of occurrence.

We report a case of eosinophilic pustular folliculitis in a 6-month-old male infant who had pruritic, tiny, erythematous papulopustules on his scalp and eosinophilia in the peripheral blood. Histopathologic examination revealed an acute follicu1ar and perifollicular inflammatory infiltrate with abundant eosinophils. The patient responded to systemic and topical corticosteroid and dapsone.

Discoid meniscus in the knee joint is common. From July 1990 through June 1994, the authors performed arthroscopy on 968 symptomatic knee joints. One hundred and six knees of 102 patients had discoid meniscus. Of the 106 knees, 14(13.2%) cases were associated with other intraarticular anatomic variants. There were 7(6.6%) cases with anomalous insertion of the anterior horn of the medial meniscus into the anterior cruciate ligament, and 7(6.6%) cases with anterior transposition of the insertion of the anterior cruciate ligament below the anterior tibial margin like the insertion of the posterior cruciate ligament. Of the 14 patients, the discoid meniscus were reshaped in 11 knees, partially resected in 2 knees, and one patient was treated with repair of a peripheral tear and reshaping. But had no treatment in associated intraarticular anatomic variants. The follow up was done from 24 to 54 months(average 37 months) after surgery. The results were excellent in 8 knees ; good in 4 knees and fair in 2 knees(Ikeuchi scale, 1982) The patients with excellent or good results were satisfied as were the authors, and these anatomical variants other than the discoid meniscus were not related to the patient's symptoms.
