An 84-year-old woman had an ovoid shallow ulcer with an elevated, indurated, pigmented border on the left cheek. Histological examination revealed a moderately differentiated squamous cell carcinoma and a solar keratosis with abundant melanocytes and melanin pigment. Ultrastructurally, the keratinocytes contained numerous melanosomes in their cytoplasms and the melanocytes in the squamous cell carcinoma and the solar keratosis had mature melanosomes.

BACKGROUND: Positive end expiratory pressure (PEEP) ventilation is well established as an integral part of the management of patients with the acute lung injury. PEEP is a key element in the treatment of hypoxemia resulting from pulmonary edema. Pulmonary capillary pressure (Pcap) is the most important factor influencing lung edema formation, and an understanding of how Pcap is altered by variations of PEEP or pulmonary arterial occlusion pressure (PAOP) is important to improve the treatment of acute lung injury patients. This study was performed to evaluate the effects of PEEP on the pulmonary capillary pressure in acute lung injury patients. METHODS: This was a prospective study of 11 acute lung injury patients. The effect of PEEP on pulmonary circulation at four different levels (0,4,8, and 12cm H2O) was analyzed. Pcap was estimated visually at bed side with Swan Ganz catheters. The pulmonary vasculature was analyzed by calculating the pressure difference at the arterial and venous parts of the circulation. RESULTS: As PEEP increased from 0 to 12 cm H2O, the mean puhnonary arterial pressure (PAP) and Pcap increased respectively from 22.7 ± 7.4 to 25.3 ± 7.3 mmHg and 15.3 ± 3.3 to 17.8 ±3.2 mmHg (p<0.05). Similarly, PAOP increased from 9.8 ± 2.1 to 12.8 ± 2.1 mmHg and the central venous pressure increased from 6.1 ± 1.6 to 9.3 1: 2.3 mmHg(p<0.05). However, the pressure gradient at the arterial (PAP-Pcap) and venous (Pcap-Pcwp) part of pulmonary circulation remained unchanged at all evaluated PEEP levels. CONCLUSION: Although Pcap increasoo gradually with increased PEEP, the pressure gradient at the arterial and venous part of the pulmonary vasculature remained unchanged at all evaluated PEEP levels in acute lung injury patients.

Protein, and essential nutrient for the growth of children, is the chief nitrogenous substant in the serum of humans. For the purpose of establishment of the normal data for evaluation of nitrogen balance, we examined the serum levels of urea nitrogen, creatinine, uric acid and serum amylase activity as well as that of protein in 560 normal school children. The results are as follows; 1. The serum level of protein is 6.1+/-0.75mg%, albumin; 3.9+/-0.57gm%, globulin ; 2.2 +/- 0.77gm%, urea nitrogen ; 14+/-3.8mg%, creatinine; 0.5+/-0.20mg%, uric acid; 3.9+/-0.91mg%, and the serum amylase activity is 127+/-41.4% units/dl. And the reference rnage of the above data is 4.6~7.6gm%, 3.3~4.4mg%, 1.5~3.0gm%, 7~22 mg%, 0.3~0.7mg%, 2.1~5.7mg% and 45~210 units/dl, respectively. 2. There is evidence of age relationship in the serum level of urea nitrogen which tends to increase with age. 3. We observed sex differences in the serum levels of total protein and albumin examined and those of urea nitrogen and creatinine examined, female was predominant in the former and male in the latter.

Fluoroscopy guidance is useful to confirm anatomical landmark and needle location for spine intervention; however, it can lead to radiation exposure in patients, physicians, and medical staff. Physicians who used fluoroscopy should be cognizant of radiation exposure and intend to minimize radiation dose. We retrospectively reviewed three lumbar spine intervention procedures (nerve root block, medial branch block, and facet joint block) at our institution between June and December, 2014. We performed 268 procedures on 220 patients and found significant difference in radiation dose between two groups classified by performing physicians. The physician who controlled the fluoroscopy unit directly used significantly shorter fluoroscopy (6 seconds) that resulted in a smaller radiation dose (dose area product [DAP] 0.59 Gy.cm2) than the physician supervising the radiographer controlling the fluoroscopy unit (72 seconds, DAP 5.31 Gy.cm2, P < 0.001). The analysis indicates that the difference in fluoroscopy time depends on whether a physician or a radiographer controls the fluoroscopy unit.

Gastric volvulus can either present as an acute or chronic symptoms according to the degree of gastric rotation and subsequent obstruction. The diagnosis of gastric volvulus is often difficult and is mainly based on imaging studies. We describe a case of mesenteroaxial gastric volvulus associated with paraesophageal hernia, well demonstrated on upper gastrointestinal (UGI) series and coronal reconstructed CT image.

PURPOSE: Although common femoral artery endarterectomy (CFAE) is regarded as the standard treatment modality for common femoral artery (CFA) disease, availability of advanced endovascular techniques has resulted in an increased number of CFA disease being treated. We evaluated clinical outcomes in a contemporary series of patients who were treated for CFA disease using endarterectomy alone or combined with endovascular treatment. MATERIALS AND METHODS: We retrospectively reviewed 46 patients from November 2001 through December 2007. The treated lesions were divided into 4 groups based on operative procedure: group I (n=11), CFAE alone; group II (n=15), CFAE and iliac artery (IA) endovascular treatment; group III (n=6), CFAE and superficial femoral artery (SFA) endovascular treatment; group IV (n=14), CFAE and IA and SFA endovascular treatment or bypass surgery. RESULTS: The degree of CFA steno-occlusion was not different among the groups. The 3-year primary patency rates of each group were 88.9±10.5%, 60.0±14.5%, 62.5±21.3%, and 83.9±10.4%, respectively. The 3-year primary assisted patency rates were 100%, 70.0±13.0%, 62.5±21.3%, and 89.3±10.4%, while 3-year secondary patency rates were 100%, 80.0±13.0%, 62.5±21.3%, and 92.3±7.4%, respectively. There was no procedure-related mortality. Significant improvement of ankle-brachial index was achieved in all groups. CONCLUSION: CFAE alone is the treatment of choice for excellent patency and clinical improvement in steno-occlusive lesions confined to the CFA. In multiple steno-occlusive diseases, this procedure could be combined with endovascular procedures to reduce the operative risk in conditions with high morbidity.

BACKGROUND: To evaluate the feasibility of noninvasive hemodynamic monitoring (impedance cardiography, ICG) in critically ill patients, we compared this technique with simultaneous invasive monitoring with a pulmonary artery thermodilution catheter. METHODS: A prospective observational study was done comparing invasive monitoring and noninvasive monitoring in 12 critically ill patients. The cardiac output (CO), the stroke volume (SV) and the systemic vascular resistance (SVR) measured by using a standard thermodilution pulmonary artery catheter technique were compared with the corresponding measurements simultaneously using an ICG. RESULTS: The value of CO, SV and SVR measured by ICG were closely correlated to those by the thermodilution methods [r: 0.659 (p<0.01), 0.536 (p<0.01), 0.738 (p<0.01)]. CONCLUSIONS: ICG can provide hemodynamic information previously available only by invasive monitoring with a thermodilution catheter.

Objectives:
To assess the trends and disparities in the utilization of F-18 fluorodeoxyglucose positron emission tomography/ computed tomography (FDG PET/CT) in Korea between 2018 and 2022, with a focus on disease classification, patient demographics, and regional distribution.
Methods:
This national surveillance retrospective study uses data from the Health Insurance Review and Assessment Service (HIRA) database, which includes all FDG PET/CT examinations conducted in Korea from 2018 to 2022. Disease classifications, cancer types, age groups, gender, and geographic regions were analyzed using descriptive statistics. Utilization rates per 100,000 population were calculated for regional comparisons.
Results:
FDG PET/CT utilization increased by 25.4%, from 174,885 examinations in 2018 to 219,377 in 2022. Older age groups (60 years and above) accounted for the majority of examinations, with males undergoing more examinations than females. Oncology remained the primary indication, with lung, colorectal, and non-Hodgkin lymphoma leading in examination numbers. The number of examinations performed on patients aged 60 and above increased at a higher rate compared to those under 60. Significant geographic disparities were found, with Seoul reporting the highest utilization rate (1,114.3 examinations per 100,000 population), while Gyeongbuk exhibited much lower rate (26.2 examinations per 100,000 population).
Conclusions
This study highlights the growing utilization of FDG PET/CT in Korea, particularly among older adults, with significant gender differences in cancer types. The findings also reveal disparities in FDG PET/CT utilization across regions, indicating varying access to advanced imaging technology.
