BACKGROUND: Photoaged skin is characterized by actinic skin lesions such as wrinkling, elastosis, and premalignant and malignant lesions. Actinic keratosis (AK) is one of the most common precancerous lesions, and multiple actinic keratosis lesions are one of the risk factors for skin cancer. Few studies have investigated the prevalences of actinic skin lesions and compared the characteristics of the lesions and the patients with sinle and multiple AK lesions. OBJECTIVE: The aim of this study was to evaluate the prevalences of actinic skin lesions and to compare characteristics between single and multiple lesions in Korean patients with AK. METHODS: We retrospectively reviewed the medical records and biopsy specimens of 61 patients. RESULTS: Frequencies of deep wrinkle, solar elastosis, cutis rhomboidalis nuchae, and senile purpura were higher in the multiple lesions group. The ratio of males to females was 1:3.43 and the mean age was 79 years in the multiple lesions group, both of which were higher than those in the single lesion group (1:1.14, 72 years). The mean duration was longer in the multiple lesions group. Sun protective behavior was more frequent in the single lesion group, and the occupation of farmer was more common in the multiple lesions group. There was no statistically significant clinicopathological difference between the two groups. CONCLUSION: This study may improve our understanding of the characteristics of actinic keratosis with both single and multiple lesions.

PURPOSE: In this retrospective study, we analyzed the outcomes of prostate cancer patients treated with the CyberKnife radiotherapy system (Accuray). MATERIALS AND METHODS: Between 2007 and 2010, 31 patients were treated for prostate cancer by use of the CyberKnife radiotherapy system. After excluding six patients who were lost to follow-up, data for the remaining 25 patients were analyzed. Patients were divided into the CyberKnife monotherapy group and a postexternal beam radiotherapy boost group. Clinicopathologic features and treatment outcomes were compared between the groups. The primary endpoint was biochemical recurrence-free survival period based on the Phoenix definition. Toxicities were evaluated by using the Radiation Therapy Oncology Group scoring criteria. RESULTS: Of 25 patients, 17 (68%) and 8 (32%) were classified in the monotherapy and boost groups, respectively. With a median follow-up of 29.3 months, most of the toxicities were grade 1 or 2 except for one patient in the boost group who experienced late grade 3 gastrointestinal toxicity. The overall biochemical recurrence rate was 20% (5/25) and the median time to biochemical recurrence was 51.9 months. None of the patients with low or intermediate risk had experienced biochemical recurrence during follow-up. Among D'Amico high-risk populations, 16.7% (1/6) in the monotherapy group and 50.0% (4/8) in the boost group experienced biochemical recurrence. CONCLUSIONS: Our data support that prostate cancer treatment by use of the CyberKnife radiotherapy system is feasible. The procedure can be a viable option for managing prostate cancer either in a monotherapy setting or as a boost after conventional radiotherapy regardless of the patient's risk stratification.

BACKGROUND: Administering extracorporeal membrane oxygenation (ECMO) to critically ill patients with acute respiratory distress syndrome has substantially increased over the last decade, however administering ECMO to patients with hematologic malignancies may carry a particularly high risk. Here, we report the clinical outcomes of patients with hematologic malignancies and severe acute respiratory failure who were treated with ECMO. METHODS: We performed a retrospective review of the medical records of patients with hematologic malignancies and severe acute respiratory failure who were treated with ECMO at the medical intensive care unit of a tertiary referral hospital between March 2010 and April 2015. RESULTS: A total of 15 patients (9 men; median age 45 years) with hematologic malignancies and severe acute respiratory failure received ECMO therapy during the study period. The median values of the Acute Physiology and Chronic Health Evaluation II score, Murray Lung Injury Score, and Respiratory Extracorporeal Membrane Oxygenation Survival Prediction Score were 29, 3.3, and -2, respectively. Seven patients received venovenous ECMO, whereas 8 patients received venoarterial ECMO. The median ECMO duration was 2 days. Successful weaning of ECMO was achieved in 3 patients. Hemorrhage complications developed in 4 patients (1 pulmonary hemorrhage, 1 intracranial hemorrhage, and 2 cases of gastrointestinal bleeding). The longest period of patient survival was 59 days after ECMO initiation. No significant differences in survival were noted between venovenous and venoarterial ECMO groups (10.0 vs. 10.5 days; p = 0.56). CONCLUSIONS: Patients with hematologic malignancies and severe acute respiratory failure demonstrate poor outcomes after ECMO treatment. Careful and appropriate selection of candidates for ECMO in these patients is necessary.

Purpose:
The aim of this study was to investigate the prognostic impact of time to percutaneous nephrostomy (PCN) insertion on obstructive ureteral stones with sepsis.
Materials and Methods:
Data were collected on patients who presented at our Emergency Department between 2017 and 2021 with obstructive uropathy due to urinary stones and underwent PCN insertion. Patients were stratified into 4 groups in accordance with the quick sepsis-related organ failure (qSOFA) score at presentation (<2 or ≥2) and time to PCN insertion (<4 hours or ≥4 hours) as follows: group 1, qSOFA < 2 and time to PCN insertion < 4 hours; group 2, qSOFA < 2 and time to PCN insertion ≥ 4 hours; group 3, qSOFA ≥ 2 and time to PCN insertion < 4 hours; group 4, qSOFA ≥ 2 and time to PCN insertion ≥ 4 hours. The prognostic impacts of the time to PCN insertion were compared between these groups
Results:
The total cohort consisted of 96 patients, of whom 70 were classified as either group 1 or 2 (qSOFA < 2). Overall, 37 patients had a positive urine culture. The median time to PCN insertion was 218 minutes, and the median length of stay was 14 days. The hospitalization period was significantly shorter in group 3 than in group 4 (p=0.041).
Conclusions
A shorter length of stay was associated with more rapid PCN insertion in patients with obstructive uropathy and a high risk of sepsis.

Myxedema coma is the most extreme form of hypothyroidism and manifests as central nervous system dysfunction, defective thermoregulation, and cardiopulmonary decompensation. The curative treatment is based on the administration of thyroid hormones, but the dose and route of administration remain controversial. Here, we report a case of myxedema coma that was treated successfully with a large oral dose of levothyroxine
