Purpose:
To retrospectively evaluate the chest computed tomography (CT) findings of coronavirus disease 2019 (COVID-19) in patients with mild clinical symptoms at a single hospital in South Korea.
Materials and Methods:
CT scans of 87 COVID-19 patients [43 men and 44 women; median age:41 years (interquartile range: 26.1–51.0 years)] with mild clinical symptoms (fever < 38℃ and no dyspnea) were evaluated.
Results:
CT findings were normal in 39 (44.8%) and abnormal in 48 (55.2%) patients. Among the 48 patients with lung opacities, 17 (35.4%) had unilateral disease and 31 (64.6%) had bilateral disease. One (2.1%) patient showed subpleural distribution, 9 (18.8%) showed peribronchovascular distribution, and 38 (79.2%) showed subpleural and peribronchovascular distributions.Twenty-two (45.8%) patients had pure ground-glass opacities (GGOs) with no consolidation, 17 (35.4%) had mixed opacities dominated by GGOs, and 9 (18.8%) had mixed opacities dominated by consolidation. No patients demonstrated consolidation without GGOs.
Conclusion
The most common CT finding of COVID-19 in patients with mild clinical symptoms was bilateral multiple GGO-dominant lesions with subpleural and peribronchovascular distribution and lower lung predilection. The initial chest CT of almost half of COVID-19 patients with mild clinical symptoms showed no lung parenchymal lesions. Compared to relatively severe cases, mild cases were more likely to manifest as unilateral disease with pure GGOs or GGOdominant mixed opacities and less likely to show air bronchogram.

BACKGROUND: The currently available ldegrees Cal anesthetics have limitations in action duration. The duration ranges from 3 to 8 hours. Long acting anesthetic agents are particularly desirable to manage postoperative pain, relieve severe pain assdegrees Ciated with terminal cancer, and for nerve bldegrees Cks carried out in pain clinics. In this paper mixture of ldegrees Cal anesthetics was formulated into cylindrical pellet using biodegradable polymer and its efficacy and safety was evaluated. METHODS: Pellets were prepared by modified melting prdegrees Cess with biodegradable polyester 30 wt%, bupivacaine 35 wt%, liddegrees Caine 35 wt% and dexamethasone 0.05 wt% of polymer and drug. In vitro release kinetics of ldegrees Cal anesthetics from pellet were determined in PBS at pH 7.4, 37degrees C, and the released ldegrees Cal anesthetics were analyzed by HPLC. Nine male Sprague Dawley weighing 300~350 gm were implanted with pellets along the sciatic nerve and the sensory bldegrees Ckade was assessed by an analgesiometer. The duration data were analyzed by paired t-test using SAS 6.11. RESULTS: Ldegrees Cal anesthetics were released in a controlled manner in vitro. In general, 40~50% of the drug released for the first day, and thereafter approximately 5% released daily. Sensory bldegrees Ckade lasted to beyond 2 days at the dose of 7 mg/100 g bupivacaine and liddegrees Caine respectively. All of the animals exhibited no systemic toxicity and complete recovery. CONCLUSIONS: The results indicated that the mixture pellet demonstrated efficient and safe in prolongation of sensory bldegrees Ckade for significant period of time. The mechanisms underlying the mixture effect are under investigation.

BACKGROUND: Transperitoneal laparoscopy for renal surgery is now a common procedure. Previous studies have suggested that retroperitoneal laparoscopy is associated with greater carbon dioxide absorption. We compared carbon dioxide absorption and hemodynamic variables in patients undergoing transperitoneal laparoscopy for renal or adrenal surgery with that of patients undergoing intraperitoneal laparoscopy for colon surgery. METHODS: Thirty two patients undergoing laparoscopic surgery were divided into laparoscopic renal surgery group (n = 16) and laparoscopic colon surgery group (n = 16). We measured hemodynamic changes and arterial blood gases before CO2 insufflation, 10 minutes, 70 minutes after insufflation and 30 minutes after exsufflation in each groups. RESULTS: There was no significant difference in carbon dioxide absorption in patients who underwent transperitoneal laparoscopy compared to intraperitoneal laparoscopy at any interval. CONCLUSIONS: In contrast to previous reports, our study suggests that transperitoneal laparoscopy is not associated with greater carbon dioxide absorption compared to intraperitoneal laparoscopy.
