Novel reconstruction method using long and narrow gastric tube in laparoscopic proximal gastrectomy for cancer: a retrospective case series study.

Background and objectives: To clarify the safety and feasibility of laparoscopic proximal gastrectomy (LPG) with our novel reconstruction methods. Methods: Novel method is a reconstruction with a long and narrow gastric tube with widening of the proximal side created by linear stapler, and esophagogastrostomy is performed by linear stapler. In conventional method, esophagogastrostomy is performed by a circular stapler. Short- and long-term outcomes of a novel method were compared with those of conventional method. Results: A total of 44 patients whom LPG was performed were enrolled in this retrospective study. No cases of anastomotic leakage and stenosis were observed in both groups. The cases of postoperative reflux esophagitis (Grade B or higher) at 1 year after operation in the Novel group were less than those in the Conventional group (17% vs. 44%). Conclusion: LPG with novel reconstruction method can be easily performed, and may be feasible for the treatment of proximal gastric cancer.

Anxious temperament as a risk factor of suicide attempt.

OBJECTIVE: Suicide has been reported to be associated with cyclothymic, irritable, depressive and anxious temperaments. In contrast, hyperthymic temperament has been reported to be protective against suicide. In the present study, we hypothesized that Japanese patients with suicide attempt may have higher scores of cyclothymic, irritable, depressive, and anxious temperaments but lower scores of hyperthymic temperament than non-suicidal patients. In order to examine this hypothesis, we investigated Japanese patients of a university emergency center. METHODS: The association of temperament and suicide attempt was investigated in 116 patients referred to a university emergency center for intoxication or injury. Of them, 35 patients of suspected suicide attempt were categorized as 18 patients who intended to die with attempted suicide and suffered from self-inflicted but not fatal injury (Suicide Attempt II), 4 patients whose intention to die were undetermined although they suffered from self-inflicted injury (Undetermined Suicide-Related Behavior II), and 13 patients who had no intention to die although they suffered from self-inflicted injury (Self-Harm II). Logistic regression analyses and multiple regression analyses were used to identify factors associated with the present suicide attempt and the number of suicide attempts, respectively. RESULTS: Anxious temperament scores were significantly and directly associated with Suicide Attempt II group whereas irritable temperament scores were associated with Self-Harm II group. CONCLUSION: The present findings suggest that those with anxious temperament may have more suicide attempts than those with other temperaments, indicating anxious temperament as a risk factor of suicide attempt.

Trace lithium is inversely associated with male suicide after adjustment of climatic factors.

BACKGROUND: Previously, we showed the inverse association between lithium in drinking water and male suicide in Kyushu Island. The narrow variation in meteorological factors of Kyushu Island and a considerable amount of evidence regarding the role of the factors on suicide provoked the necessities of adjusting the association by the wide variation in sunshine, temperature, rain fall, and snow fall. METHODS: To keep the wide variation in meteorological factors, we combined the data of Kyushu (the southernmost city is Itoman, 26°) and Hokkaido (the northernmost city is Wakkanai, 45°). Multiple regression analyses were used to predict suicide SMRs (total, male and female) by lithium levels in drinking water and meteorological factors. RESULTS: After adjustment of meteorological factors, lithium levels were significantly and inversely associated with male suicide SMRs, but not with total or female suicide SMRs, across the 153 cities of Hokkaido and Kyushu Islands. Moreover, annual total sunshine and annual mean temperature were significantly and inversely associated with male suicide SMRs whereas annual total rainfall was significantly and directly associated with male suicide SMRs. LIMITATIONS: The limitations of the present study include the lack of data relevant to lithium levels in food and the proportion of the population who drank tap water and their consumption habits. CONCLUSIONS: The present findings suggest that trace lithium is inversely associated with male but not female suicide after adjustment of meteorological factors.

Severe hypothermia secondary to spinal cord injury without radiographic abnormality.

Case: A 64-year-old female was found lying by a river. She was unconscious and her lower body was under water. The patient was transported to the emergency room of our hospital. On arrival, her rectal temperature was 24.6°C. We immediately started rewarming and artificial respiration. Five days after admission, rewarming was completed and she became conscious and could communicate. Initially, she had been injured and examination showed paraplegia. Magnetic resonance imaging of her cervical spine showed no findings indicating bony or ligament injury, but there was a T2 high intensity area at C5/6 and C6/7 levels. The patient was diagnosed with spinal cord injury without radiological abnormality. Outcome: At 5 months post-injury, the patient was able to walk without crutches. Conclusion: Spinal cord injury might be missed if there are no radiographic abnormalities. Spinal cord injury without radiological abnormality should be considered as a differential diagnosis of accidental hypothermia.
