PURPOSE: Thrombocytosis is reported in patients with various tumors, including stomach, colon, ovarian, lung and pancreatic cancers. Some clinical reports have shown thrombocytosis to be a poor prognostic factor in cancer patients. However, in hepatocellular carcinoma patients, the incidence and clinical significance of thrombocytosis have not been clearly verified. In this study, the clinical significance of platelet counts was investigated in patients with hepatocellular carcinomas. METHODS: 212 patients with surgically proven hepatocellular carcinomas were enrolled in this study. The incidence, relationship with other clinicopathological factors, and the prognostic value of thrombocytosis were retrospectively evaluated. RESULTS: The incidence of thrombocytosis (> or =400, 000/ul) was 2.8% (6/212). The platelet counts were elevated in patients with a large sized tumor (p< 0.001), advanced TNM stage (p=0.009) and gross tumor thrombi in the portal vein (p=0.009). There was no difference in the survival between patients with low and high platelet counts. CONCLUSION: The incidence of thrombocytosis in hepatocellular carcinoma patients was very low. The platelet counts were elevated in patients with advanced hepatocellular carcinomas, but no prognostic significance was shown in this study.

A folk prescription consisting of Alnus hirsuta, Rosa davurica, Acanthopanax senticosus and Panax schinseng has been used in the treatment of diabetes mellitus. The aim of the present investigation was to evaluate the antidiabetic effects of the herb formula extract (HFE) composed of Alnus hirsuta, Rosa davurica, Acanthopanax senticosus and Panax schinseng in the streptozotocin (STZ)-induced diabetic rats. The HFE was mixed in the food supply of the healthy and STZ-induced diabetic male Sprague-Dawley rats, and its effects on the body weight, water and food intake, hyperglycemia, hypolipidemic and islet structure were studied. The treatment of the rats with STZ for 6 weeks resulted in marasmus, polydipsia, polyphagia, hyperglycemia and hypoinsulinemia. In addition, the diabetic rats showed an apparent decrease in the insulin immunoreactivity and the number of beta-cells in the pancreas. The addition of the HFE to the rats' food supply significantly lowered the serum glucose and the serum triglycerides level and preserved the normal histological appearance of the pancreatic islets. These results indicate that the HEF have a strong antidiabetic potential along with the significant hypoglycemic and hypolipidemic effects, which may be applicable in the pharmaceutical industry.

Gangliogliomas are rare benign tumors of the central nervous system consisting of neoplastic ganglion and low grade glial cells. The purpose of our investigation was to evaluate the clinical, radiological, surgical, and pathological features and outcome of ten patients with intracranial ganglioglioma who underwent surgery between June 1989 and December 1996. The mean follow-up period was about 24 months(range, 6-66 months) after their initial operation. The series consisted of six males and four females, and their mean age was 29.7 years. The mean length of symptoms was 9.1 years. Seizure was the most common presenting symptom and occurred in eight of ten patients. MRI findings were variable, and showed no characteristic patterns. The temporal lobe was the most common site of involvement(6/10). During surgery, a sharp demarcation between tumor and normal brain tissue was seen in seven of ten cases. Five of ten cases were solid, and the remaining cases were cystic in two, cystic with mural nodule in two, and soft, suckable in one. Total resection was possible in seven of ten patients. Diagnosis was established by identifying a mixture of abnormal astrocytic and neuronal components. Two patients showed astrocytic predominance; four, a neuronal predominance; and four, an equal admixture of cell types. All cases were benign. Other histopathological findings included microcystic change, desmoplasia, eosinophilic granular body, microcalcification, and lymphocytic infiltration. At the time of writing, all seven patients who underwent total resection were alive without recurrence; of the three who underwent subtotal resection, two were alive and in a stable condition, while in the other, the tumor had progressed within 12 months of surgery and adjuvant radiation therapy had thus been required. The patients was, though, still alive. In seven of eight patients, the frequency of seizure had markedly decreased. Our study confirms that this tumor is a distinct clinical and histological entity with a predilection for the temporal lobe. Although the number of patients and follow-up period are limited, this study also shows that epilepsy is extremely well controlled and that survival after surgical resection is good.

BACKGROUND: Spinal zaprinast, phospodiesterase inhibitor, has been shown to have an antinociception through an increase of cGMP. The aim of this study was to examine the role of spinal adrenergic and cholinergic receptors on the antinociceptive action of intrathecal zaprinast. METHODS: Rats were implanted with lumbar intrathecal catheters. After formalin injection, formalin-induced nociceptive behavior (flinching response) was observed for 60 min. After observing the effect of intrathecal zaprinast, antagonism of intrathecal prazosin, yohimbine, atropine and mecamylamine for the effect of zaprinast were evaluated. RESULTS: Intrathecal zaprinast produced a dose-dependent suppression of formalin-induced flinches in both phases of the formalin test. Intrathecal prazosin reversed the antinociception of zaprinast in phase 2, but not phase 1. Intrathecal yohimbine reversed the antinociception of zaprinast in both phases. Neither atropine nor mecamylamine reversed the antinocicetive action of zaprinast. CONCLUSIONS: Intrathecal zaprinast is against the nociceptive state evoked by formalin stimulus. Alpha 2 or alpha 1 adrenergic receptor, but not cholinergic receptors, may be related to the action of zaprinast in the spinal cord.

PURPOSE: This study tried to find the most significant factors predicting implant prognosis using machine learning methods. MATERIALS AND METHODS: The data used in this study was based on a systematic search of chart files at Seoul National University Bundang Hospital for one year. In this period, oral and maxillofacial surgeons inserted 667 implants in 198 patients after consultation with a prosthodontist. The traditional statistical methods were inappropriate in this study, which analyzed the data of a small sample size to find a factor affecting the prognosis. The machine learning methods were used in this study, since these methods have analyzing power for a small sample size and are able to find a new factor that has been unknown to have an effect on the result. A decision tree model and a support vector machine were used for the analysis. RESULTS: The results identified mesio-distal position of the inserted implant as the most significant factor determining its prognosis. Both of the machine learning methods, the decision tree model and support vector machine, yielded the similar results. CONCLUSION: Dental clinicians should be careful in locating implants in the patient's mouths, especially mesio-distally, to minimize the negative complications against implant survival.

Background:
Endothelial activation and stress index (EASIX) reflects endothelial dysfunction or damage. Because endothelial dysfunction is one of the key mechanisms, a few studies have shown the clinical usefulness of original and age-adjusted EASIX (age-EASIX) in patients with coronavirus disease 2019 (COVID-19). We aimed to evaluate the clinical utility of age-EASIX in predicting intensive care unit (ICU) mortality in critically ill patients with COVID-19 in South Korea.
Methods:
Secondary analysis was performed using clinical data retrospectively collected from 22 nationwide hospitals in South Korea between January 1, 2020, and August 31, 2021. Patients were at least 19 years old and admitted to the ICU for severe COVID-19, demanding at least high-flow nasal cannula oxygen therapy. EASIX [lactate dehydrogenase (U/L)×creatinine (mg/dL)/platelet count (109 cells/L)] and age-EASIX (EASIX×age) were calculated and log2-transformed.
Results:
The mean age of 908 critically ill patients with COVID-19 was 67.4 years with 59.7% male sex. The mean log2 age-EASIX was 7.38±1.45. Non-survivors (n=222, 24.4%) in the ICU had a significantly higher log2 age-EASIX than of survivors (8.2±1.52 vs. 7.1±1.32, p<0.001). log2 age-EASIX was significantly associated with ICU mortality (odds ratio, 1.541; 95% confidence interval, 1.322 to 1.796; p<0.001) and had a better area under the receiver operating characteristic curve than of the sequential organ failure assessment (SOFA) score in predicting ICU mortality (0.730 vs. 0.660, p=0.001).
Conclusion
Age-EASIX is significantly associated with ICU mortality and has better discriminatory ability than the SOFA score in predicting ICU mortality.

Clinics in Orthopedic Surgery 2024;16(2):326-334
Background:
The use of electric scooters (e-scooters) continues to increase as a simple, inexpensive means of transport, resulting in a sharp increase in the incidence of scooter-related accidents. No study to date has closely examined the injury extent to the lower leg, joints, and extremities from e-scooter-related accidents. Here, we investigated the epidemiology and injury patterns of such accidents, focusing on injuries to the ankle and foot.
Methods:
Based on data from a single tertiary hospital’s database, the demographics of 563 patients with scooter-associated injuries were analyzed retrospectively. Among the patients, 229 patients who were injured by e-scooter riding were further investigated. Based on the data, the general demographics of whole scooter-associated injuries and the injury characteristics and fracture cases of the lower leg, ankle, and foot were analyzed.
Results:
During the 4-year study period, the number of patients injured by e-scooters increased every year. Lower extremities were the most common injury site (67.2%) among riders, whereas injuries to the head and neck (64.3%) were more common in riders of non-electric scooters. Among the lower leg, ankle, and foot injuries of riders (52 cases), the ankle joint (53.8%) was the most commonly injured site, followed by the foot (40.4%) and lower leg (21.2%). The fracture group scored significantly higher on the Abbreviated Injury Scale than the non-fracture group (p < 0.001). Among the fracture group (20 cases), ankle fractures (9 cases) were most common, including pronation external rotation type 4 injuries (4 cases) and pilon fractures (2 cases). Five patients (25%) had open fractures, and 12 patients (60%) underwent surgical treatment.
Conclusions
The ankle and foot are the most common injury sites in e-scooter-related accidents. Given the high frequency and severity of e-scooter-related ankle and foot injuries, we suggest that more attention be paid to preventing these types of injuries with greater public awareness of the dangers of using e-scooters.
