Basta(R) is one of the Phospho-amino acid group herbicide. It consist of glufosinate ammonium (18.5%), alkylether sulfate as surfactant (30%) and some solvents. Although it's WHO classification is Bade III, the intoxicated patient appears an serious clinical findings and have a 20% mortality rate. Nowadays, in Korea the ingestion of herbicidal agents for suicidal attempts is Sequent. The literature for intoxication of bipyridilium (Gramoxon(R)) as herbicide is varied, but the information for Basta(R) is poor even though the use of it tends to increase. Recently, We experienced six cases of Basta(R) intoxication and found that the patient expressed a gradually progressed depression of mentation, recent memory disturbances, convulsions, hypotension, or bradycardia because of CNS or cardiovascular effects of Basta(R) We report these cases with literature review.

Since Whitehead had described a circular hemorrhoidectomy in 1882, many surgeons adopted it for decades for patients with protruding anal deformity. After a few decades of performing Whitehead operation, devastating complications such as anal stricture, fecal incontinence, and wet anus with mucosal eversion had been reported on the literatures and then it was buried as an abandoned procedure by surgeons for a long period. Recently, a few prominent anal surgeons reported that they could avoid such devastating complications by introducing diverse modifications of the original Whitehead's operation. The authors analyzed 22 patients who had undergone original Whitehead circular hemorrhoidectomy with the technique of preserving most of the perianal skin and W-shaped circular incision during the period from 1991 to 1996, with special regard to the com plications such as anal stricture and anal mucosal eversion which have been debated on so far and reviewed the articles about these issues. In immediate postoperative period, suture failure and resultant non-surgery requiring, mild anal stricture were documented in 3 of the 22 cases(13.6%). On long-term follow-up with the mean period of 44 months (18~79 months) in 14 cases, except those 8 cases that were lost, with phone-call questionaire, 13 patients(93%) had quite normal anal functions. The authors would like to suggest that the original Whitehead's circular hemorrhoidec tomy is a valuable surgical technique to manage the protruding anal deformity if surgeons can avoid well known complications such as anal stricture and anal mucosal eversion by choosing a correct location of initial W-shaped incision to preserve as much perianal skin as possible.

BACKGROUND: The self-inflating bag-valve resuscitator is an useful breathing support equipment in the cardiopulmonary resuscitation, the transportation of patients who required ventilation assist, or respiratory therapy. The inspiratory oxygen concentration (FiO2) or tidal volume (VT) delivered to the patient depends on various conditions during bag-valve ventilation. METHODS: During bag-valve ventilation without a reservoir at oxygen flow rates of 10 l/min, we evaluated fifty six volunteers to determine the FiO2 and VT at ventilatory frequencies of 10, 12 and 15 cycles per minute and to observe the effect of hand size and grasp power on FiO2 and VT in two-hand compression methods. RESULT: The FiO2 at frequency of 10 cycles/min were 50.1% and it was higher than other ventilatory frequencies. However, the VT was not statistically different among the changes of ventilatory frequency. In the change of VT according to characteristics of the hand, the operator's hand size exerted influence on VT(larger vs. smaller ; 942ml vs. 885ml, p<0.05), but the grasp power of the hand did not significantly affect. Separate analyses with size or grasp power of the hand failed to reveal significant differences of the FiO2. CONCLUSION: The results suggest that a slowing of ventilatory frequency within the allowable ranges for adequate gas exchange increase the FiO2 during bag-valve ventilation without reservoir, and that hand size may exert influence on the VT without FiO2 changes but grasp power may not be a contributing factor to the VT or FiO2 changes.

BACKGROUND: Nowadays, acute drug intoxication is a important section of emergency medicine. The purpose of this study was to determine what is the best-way to manage acutely intoxicated patients with drug in emergency department setting. METHODS: Clinical assessment were made on 135 cases of drug intoxication visited to emergency center of Hospital during one year from June 1997 to May 1998. RESULTS: 1. The total number of cases of acute drug intoxication was 135 which is 0.5% of total patients presented to emergency center. 2. There was no sexual difference in incidence, but the highest incidence of age group was in 3rd decade(23.7%) and the next was 7th decade(20.0%). 3. High frequency of acute intoxication was observed in autumn. October had the largest portion in monthly distribution. The largest portion of presumed time of poisoning was noon - 4 p.m. and of the time on arrival to emergency center was 8 p.m. -midnight. 4. Suicidal attempt was the most common motive of intoxication (72.6%). 5. The most common drug of intoxication was insecticides (35.7%) and the others were centrally active agents, herbicides in orders. 6. Mental change was observed in 20.7% of patients and the abnormal vital signs were hypertension, tachycardia, and hypotension in order on arrival to emergency center. 7. Mean duration of treatment was 36.1 hours. Mortality rate of the cases was 7.4%. CONCLUSION: The mortality rate was high in patients who ingested relatively fatal drugs (i.e. herbicides, antimicrovials, insecticides), showed mental change on arrival or received mechanical ventilatory care(p<0.05).

7.The effects of COVID-19 on physician’s burnout: a systematic review
Journal of the Korean Medical Association 2021;64(9):636-646
Background:
To suggest measures to prevent burnout of physicians during the coronavirus disease 2019 (COVID-19) pandemic, we conducted a systematic review of research on physician burnout due to COVID-19.
Methods:
Three foreign databases were used: MEDLINE, Embase, and the Cochrane Library. A search was performed using the following search terms: COVID-19, coronavirus, NCOV, physicians, doctors, residents, and burnout. Four rounds of review were performed to enhance the consistency of quality assessment. The Joanna Briggs Institute checklist for analytical cross-sectional studies was used to assess the quality of the eligible studies.
Results:
A total of 465 studies were identified, of which 32 were selected. The quality assessment determined that 19 studies met the Joanna Briggs Institute criteria and had a low risk of bias. The most common tool used to measure physician burnout in the 32 studies was the Maslach Burnout Inventory.
Conclusion
This study systematically evaluated the literature on physician burnout. However, the generalizability of our findings to Korean physicians may be limited. The composition of the medical personnel in Korea, such as open doctors, volunteer doctors, medical professors, and public health doctors, differs significantly from that of other countries. Nevertheless, evaluating the current status of physician burnout due to COVID-19 globally may hold meaningful implications for policymaking.

Priapism has been classified as primary (idiopathic)and secondary according to etiology. Hemodynamically, it can be separated into two distinct types: low-flow (ischemic) and high flow (non-ischemic). In the latter type, the most common cause is blunt genital trauma, and selective cavernosal artery embolization has been the most effective therapeutic method. Two cases of high-flow arterial priapism are presented. Both cases were post-traumatic and were managed with selective cavernosal artery embolization, with excellent return of premorbid levels of erectile function.
