Diagnostic value of the placenta in medico-legal practice

In three suspected cases of infanticide, histological examinations of the placentas were effective in clarifying the circumstances. We have estimated the 5th month of pregnancy from pieces of the placenta in one case and diagnosed the causes of perinatal abnormalities in two cases, those being acute chorioamnionitis and possible premature separation of normally implanted placenta.     

A case of strangulation with postmortem amputation of the penis

A case of homicide with postmortem amputation of the penis was described. The penis found later in a home freezer in the apartment of the culprit showed "zigsaw" fit to the victim. In order to substantiate the morphological findings, phenotypes of three isozymes, phosphoglucomutase1 (PGM1), phosphogluconate dehydrogenase (PGD), and esterase D (EsD) together with ABO blood type were determined in the skin of the penis amputated. All of the four genetic markers determined with the penis were the same as those determined with heart blood of the victim.     

Autopsy report on central pontine myelinolysis triggered by vomiting associated with digoxin intoxication

An 87-year-old male, prescribed digoxin and furosemide for congestive heart failure and Alzheimer disease, had dehydration and anemia due to poor food intake and hemorrhagic cystitis. Repeated vomiting due to an upper respiratory infection caused disturbance of consciousness and hypotension. The patient was admitted to hospital and diagnosed with digoxin intoxication and hypernatremia. The serum sodium (Na⁺) level was corrected, but the patient died 4 days after admission following uncontrollable seizure. A histologic examination after an autopsy revealed characteristic findings of central pontine myelinolysis (CPM). This is the first autopsy report on CPM triggered by vomiting in association with digoxin administration.     

Does electoral competition affect politicians’ trade policy preferences? Evidence from Japan

This study examines the effect of electoral competition on politicians’ trade policy preferences using candidate observations from the House of Representatives in Japan’s 2012 general election. The study clarifies the effects of constituency size and the electoral strength of constituencies on candidates’ political stances. The empirical results provide evidence that politicians’ preferences for trade policy are sensitive to electoral pressure, but their reactions differ depending on the characteristics of each constituency. The results reveal that for a broad constituency with a large concentration of agricultural workers, election candidates are more likely to support protectionism than their counterparts running in a narrow constituency. For city district election candidates, electoral strength measured by the vote margin significantly affects their trade policy preferences. Candidates in close elections are more likely to be protectionist than candidates elected by a substantial majority, suggesting that electoral pressures deter politicians from supporting trade liberalization.     

Sudden Death Due to Recent Hemorrhage From an Intrathoracic Chronic Expanding Hematoma

Chronic expanding hematoma (CEH) is a rare disease that can develop in any region of the body, but it most frequently develops in the thorax. When intrathoracic CEH is left untreated, gradually expanding hematoma can be life‐threatening, leading to respiratory failure or hemoptysis. We encountered an 89‐year‐old man with cardiopulmonary arrest on arrival. He had been healthy, and it was unclear whether CEH had previously been detected. A very large mass was observed on chest computed tomography (CT), but the cause of death could not be determined. In the autopsy, this mass was identified as CEH and no malignant findings were noted. A fresh hemorrhage had occurred in the hematoma and perforated the bronchial lumen, which caused airway obstruction/asphyxia and resulted in sudden death. CEH should be suspected when a very large tumorous lesion occupying the entire hemithorax is observed on chest imaging, and it is important to recognize that sudden death can occur in the natural course of CEH.
