In 1971, thallium was the main poison that Graham Frederick Young used to poison around 70 people in the English village of Bovingdon, Hertfordshire, of whom three died. From 1976 to late 1979, thallium was used as a chemical warfare agent, most notably by a unit of the British South Africa Police (BSAP) attached to the Selous Scouts during the Rhodesian Bush War. In 1977, a 19 month-old girl living in Qatar fell ill due to thallium poisoning (from pesticides used by her parents). While doctors were unable to identify the cause, a nurse named Marsha Maitland managed to do it from the description of the symptoms given in The Pale Horse. In summer 1981 the East German secret service "Stasi" poisoned dissident Wolfgang Welsch, who had previously been expelled to West Germany, during his holiday in Israel. He barely survived. In 1985, spiritual leader Rajneesh was allegedly poisoned with small doses of poison, by Reagan Administration and Church, as per accounts of his followers. This allegation was never proven. He died after 5 years in 1990. In 1987, in Kyiv, a woman named Tamara Ivanutina was arrested along with her older sister and parents. They were found guilty of 40 cases of poisoning (13 of them lethal) with Clerici solution obtained from an acquaintance working at a geology institute. Tamara (guilty of nine deaths, including four children) was executed in one of the three documented cases of women receiving the capital punishment in post-Stalin Soviet Union.
Krukenberg tumors are most commonly metastases from gastric cancer, particularly adenocarcinoma, or breast cancer particularly invasive lobular breast carcinoma, but they can arise in the appendix, colon, small intestine, rectum, gallbladder, and urinary bladder or gallbladder, biliary tract, pancreas, ampulla of Vater or uterine cervix.Immunohistochemistry may help in diagnosing Krukenberg tumors from primary ovarian neoplasms but needs to be applied with discretion. For example, tumors that are immunoreactive to CEA or cytokeratin 20 (CK20) and negative for cytokeratin 7 (CK7) may be more likely to be of colorectal origin. Treatment and prognosis
Since Krukenberg tumors are secondary (metastatic), management might logically be driven by identifying and treating the primary cancer. The optimal treatment of Krukenberg tumors is unclear. The role of surgical resection has not been adequately addressed but if metastasis is limited to the ovaries, surgery may improve survival. The role of chemotherapy and/or radiotherapy is uncertain but may sometimes be beneficial. History
Krukenberg tumors are named after Friedrich Ernst Krukenberg (1871–1946),  who reported what he thought was a new type of primary ovarian malignancy in 1896;  six years later these were shown to be of metastatic gastrointestinal tract origin. However, Paget had described the process in 1854. References
