BACKGREOUND: Cerebral damage caused by hemorrhagic shock presents an important challenge for critical care medicine. The type of fluid to resuscitate hemorrhagic shock is important for the outcome of such patients. Pentastarch is low-molecular-weight hydroxyethyl starch, which increases cerebral blood flow (CBF) by plasma volume expansion and compensatory vasodilation, and improves the microcirculation in the ischemic brain area by reducing the blood viscosity. METHODS: The authors continuously determined CBF and CMRO2 in 10 mongrel dogs weighing 20.1 +/- 0.8 kg with posterior sagittal sinus outflow method. Dogs were subjected to the 20 minute-period of hemorrhagic shock to a mean arterial pressure of 40 mmHg. The shock phase was followed by resuscitation with the same volume of 10% pentastarch as blood loss. The authors assessed the changes of CBF, CMRO2, and CBF/CMRO2 ratio immediately and 30, 60, 90, 120 minutes after pentastarch infusion. Brain water content was assessed by the wet-dry weight method. RESULTS: CBF was increased above the control level, immediately and 30 minutes after 10% pentastarch infusion (p<0.05), and approximated to the control level for the remaining time. CMRO2 was increased, immediately and 30, 60, 90 minutes after 10% pentastarch infusion (p<0.05), and approximated to the control level at 120 minutes. CBF/CMRO2 ratio was recovered to the control level after 10% pentastarch infusion. Brain water content was not significantly different from the normal value of dogs. CONCLUSION: 10% pentastarch may be used with safety to resuscitate hemorrhagic shock because it recovers the balance between the cerebral oxygen supply and demand, and does not cause cerebral edema.

BACKGROUND: Direct laryngoscope may be less useful under conditions of limited visualization. Light wand is a lighted stylet to transilluminate neck tissues allowing intubation without visualization. Thus, difficult intubation due to anatomy can be overcome. For comparison of light wand and direct laryngoscope, we checked time to intubation (TTI), success rate, relation of TTI and thyromental distance (TMD), and change of blood pressure and heart rate after intubation. METHODS: We selected and randomly allocated sixty adults to direct layngoscope group (D) and light wand group (L). Without premedication, propofol and vecuronium were injected for intubation. Time to intubation was measured from the time of grasping direct laryngoscope or light wand until the time of inserting endotracheal tube into trachea. We checked the change of blood pressure and heart rate after intubation, and studied the correlation of TTI and TMD. RESULTS: TTI was 16.5 sec (6.53~115.3 sec) for group D and 11.8 sec (4.31~36.0 sec) for group L. There was no significant difference between the groups. The rise of blood pressure and heart rate was less with light wand. There was a correlation of [TTI]=1248- 388[TMD]-30[TMD]2 in group L patients whose TMD is less than 7 cm. CONCLUSION: Compared with direct laryngoscope, light wand is as easy to use and can be more effective especially for patients whose anatomy may make intubation difficult or whose cardiovascular system is unstable.

In Korea, studies of splenectomies are mainly performed in adult groups, but a review of splenectomies in children is significant because the indications of a splenectomy and the importance of the spleen in children are different from those in adults. The authors reviewed 51 cases of splenectomies performed between January 1986 and April 1996 on children under 15 years of age. The indications of the splenectomy were divided based on hematologic diseases (37) and non-hematologic diseases (14). For the hematologic diseases, hereditary spherocytosis (24) was the most common indication of a splenectomy and idiopathic thrombocytopenic purpura (11) was the next most common. For the non-hematologic diseases, trauma (10) was the most common indication of a splenectomy. After the splenectomy, abnormal hematologic findings were improved in all hereditary spherocytosis patients and in nine of the idiopathic thrombocytopenic purpura patients (82%). To prevent postsplenectomy sepsis, 27 patients received antibiotic medication, but no one received a pneumococcal vaccination. One case of postsplenectomy sepsis occurred in a patient who had not received antibiotic medication. This study suggests that a splenectomy provides efficacious treatment for a number of pediatric disorders, but it is associated with a risk of postsplenectomy sepsis.

The horse stable hand workers are one of the most important occupations in horse-racing industry. However, suicide problem of the horse stable hand workers in Korea has raised the necessity of new study on how these workers experience mental health problems such as occupational stress and depression in organizational situation. Therefore, this study investigated the occupational stress and depression level of the horse stable hand workers and identified the structural relationship in the horse-racing industry through a detailed interview. A total of 207 horse stable hand workers participated in this study, and occupational stress and depression level were surveyed using the Korean Occupational Stress Scale (KOSS) and Korean version of the Center for Epidemiologic Studies-Depression Scale (CES-D). The results of this study showed that the occupational stress level of horse stable hand workers was higher than the median of Korean population. The significant difference in occupational stress among the detail job grade was also identified. In addition, 34% of the horse stable hand workers showed high risk of depression, and job demand, organizational system, and inappropriate compensation as the subfactors of occupational stress were showed to mainly affect depression. Although there are some limitations according to the field survey, this study also has significant meaning in that it identifies the relationship between the occupational characteristics of the horse stable hand workers and the mental health. It will be necessary to study the diverse organizational situation and individual mental health for new occupations.

Gastric mixed adenoneuroendocrine carcinoma (MANEC) is an entity defined by World Health Organization in 2010, which is composed of adenocarcinoma and neuroendocrine neoplasm. This is a very rare type of tumor in the stomach, which is estimated to be one to two per one million people per year on gastrointestinal track. In general, as MANEC often shows a poor prognosis, early diagnosis of the disease is important for achieving a favorable outcome. However, due to its rarity and histological heterogeneity, it is hard to suspect this disease initially, and sometimes this tumor is misdiagnosed as adenocarcinoma. The present case was a 76-year-old man who was initially diagnosed with gastric tubular adenocarcinoma without distant metastasis. Only 1 month after a curative surgery, multiple liver metastases were newly detected. Retrospective pathologic review resulted in a revised diagnosis as a gastric MANEC, and the patient underwent palliative systemic chemotherapy to achieve partial response.

PURPOSE: The number of patients with HIV disease has been increasing rapidly, with anorectal discomfort being the most common complaint of these patients. However, there are no data on HIV disease relating to the benign anorectal area in Koreans. METHODS: A retrospective chart review was performed on patients diagnosed with benign anal diseases, combined with HIV disease, between 1996 and 2001. Their clinical aspects were compared with HIV patients registered with the National Institute of Health in Korea between 1985 and 2001. RESULTS: A total of 1,613 patients were registered, with the National Institute of Health in Korea, as having HIV disease. The ratio of sex was 7.2:1, with a male predominance. The disease was most common in the 3rd & 4th decades, with 64.2%, of the patients in this age range. As for the routes of transmission, sexual contact was the most common (96.9%), followed by blood transfusion (including blood products) (2.8%), vertical transmission (0.1%) and drug injection (0.1%). With regard to the sexual contact routes, homosexuality accounted for 28.0%. Of the cases of HIV disease presenting with a benign anal disease, 32 patients, with a sex ratio of 31:1, with an overwhelming male predominance, were selected. Twenty-six cases had been newly diagnosed at our hospital. As for the routes of the transmission, the disease had been transmitted by sexual contact in all cases. In 43.8% of these cases, the disease had been transmitted by homosexual contact, which showed a marked difference to that of the National database (P<0.05). For those associated with an anal diseases, there were 10 cases of anal fistula, 9 of perianal abscess, 7 of condyloma acuminata, 7 of anal fissure, 5 of hemorrhoids and 2 of ulceration on the lower rectum, noted. CONCLUSIONS: Nowadays, the numbers of anorectal-disease patients with HIV are increasing in Korea. Since HIV is common in the area of benign proctology, all proctologists must consider the possibility of HIV when managing patients.
