Successful treatment of Wernicke encephalopathy in terminally ill cancer patients: Report of 3 cases and review of the literature

Although Wernicke encephalopathy has been reported in the oncological literature, only one terminally ill cancer patient with Wernicke encephalopathy has been reported. Wernicke encephalopathy, a potentially reversible condition, may be unrecognized in terminally ill cancer patients. In this communication, we report three terminally ill cancer patients who developed Wernicke encephalopathy. Early recognition and subsequent treatment resulted in successful palliation of delirium. Two of the three patients did not show the classical triad of Wernicke encephalopathy. Common clinical symptoms were delirium and poor nutritional status. Intravenous thiamine administration dramatically improved the symptoms of delirium in all three patients. In terminally ill cancer patients, clinicians must remain aware of the possibility of Wernicke encephalopathy when patients with a poor nutritional status present with unexplained delirium. Early intervention may correct the symptoms and prevent irreversible brain damage and the quality of life for the patient may improve.

Wernicke encephalopathy presented in the form of postoperative delirium in a patient with hepatocellular carcinoma and liver cirrhosis: a case report and review of the literature.

OBJECTIVE Although Wernicke encephalopathy has been reported in the oncological literature, it has not previously been reported in postoperative cancer patients. METHODS In this communication, we report a patient of hepatocellular carcinoma with liver cirrhosis who developed Wernicke encephalopathy in the form of postoperative delirium. Preoperatively, the patient had a very good appetite and had eaten all the food of an 1800 cal/day diet until 1 day before operation. The operation was done without any complications. The patient developed delirium 2 days after the lobectomy of the liver. The level of delirium remained unchanged until administration of thiamine starting on day 7 postoperatively, which resulted in palliation of delirium without brain damage. Laboratory data demonstrated that the serum thiamine level at day 6 postoperatively was below the lower limit of normal. As the mechanism of Wernicke encephalopathy, we thought that decreased ability to store thiamine due to liver cirrhosis led to depletion of thiamine faster than had been expected. RESULTS AND SIGNIFICANCE OF THE RESEARCH In cancer patients, clinicians must always remain aware of the possibility of Wernicke encephalopathy, especially in patients with liver dysfunction, which decreases the ability to store thiamine in the liver. Early detection and intervention may alleviate the symptoms of delirium and prevent irreversible brain damage.

Neuroleptic malignant syndrome in cancer treatment.

OBJECTIVE Neuroleptic malignant syndrome (NMS) is a life-threatening reaction to neuroleptics. Several prospective studies have reported NMS occurrence rates ranging from 0.07% to 2.2% of patients receiving neuroleptics. However, few occurrences of NMS have been reported in cancer patients despite frequent complications of cancer and its treatment by mental disorders managed with neuroleptic drugs. Exhaustion, dehydration, and malnutrition are considered risk factors for NMS, and cancer patients represent a high risk group for NMS. METHODS We describe a patient with metastatic chondrosarcoma who had received frequent neuroleptic injections prior to brain surgery and developed NMS in the intensive care unit immediately after surgery. The patient showed delirium, hyperpyrexia, tachycardia, diaphoresis, and extrapyramidal symptoms. After a diagnosis of NMS was made, supportive care and careful monitoring were carried out, and the patient recovered over an interval of 11 days. RESULTS AND SIGNIFICANCE OF THE RESEARCH Clinical NMS studies have been conducted mainly in psychiatric units, but NMS can occur wherever psychotropic drugs are administered. NMS can be difficult to diagnose due to multiple complicating factors in cancer treatment, but the diagnosis is highly important given the risk of death. Recognition of prodromal NMS symptoms can facilitate actions to decrease morbidity and mortality. It is suggested that special attention to cancer patients undergoing psychopharmacologic treatment is required in clinical oncologic practice.

Post-traumatic stress disorder associated with suspected lung cancer and bereavement: 4-year follow-up and review of the literature.

Abstract. We report here a patient who developed post-traumatic stress disorder (PTSD) after being given a diagnosis of suspected lung cancer. The symptoms of PTSD continued even after it had been confirmed that the lesion was benign after all. A 73-year-old man was referred to our psychiatric outpatient clinic for depressed mood, appetite loss and difficulty in sleeping. On examination the patient explained that he had become preoccupied with intrusive thoughts and memories since his diagnosis of suspected lung cancer and that although he had been told the lesion was not malignant, he had distressing memories of that period and was experiencing severe psychological distress. The patient also explained that he had experienced the death of a close friend through lung cancer and he had a deep fear of developing lung cancer himself. In this patient, the psychological distress evoked by the diagnosis of suspected cancer was severe enough to induce the symptoms of PTSD even though the tumor was benign. From the clinical point of view, it could provide useful information if liaison psychiatrists were to ask patients about any experience of losing significant others to the same disease and this might be helpful in gaining an understanding of the disease process.

Victims of physical abuse among patients with cancer referred to psychiatric clinic in a cancer center hospital: a pilot study.

OBJECTIVE Physical abuse is one of the most important public health problems, but little is known about physical abuse of cancer patients. The objects of this study are (1) to identify whether cancer patients have sustained physical abuse; (2) to explore clinical characteristics of the abused patients. METHODS We reviewed 584 cancer patients referred to our psychiatry clinic by a cancer center hospital and investigated whether there were victims of physical abuse among these patients. We also investigated psychiatric characteristics of the abused patients. RESULTS Of these 584 patients, three patients were recognized as victims of physical abuse at the time of referral. The perpetrator of physical abuse was their husband (domestic violence) in all three cases. All three patients had sustained physical abuse from their husbands for years before being diagnosed with cancer. In addition to physical abuse, all three patients had sustained emotional abuse (e.g., threat or intimidation) from their husbands. Psychiatric diagnoses of all three patients fulfilled the DSM-IV criteria for post-traumatic stress disorder (PTSD) and the traumatic event was mainly physical abuse by their husbands. SIGNIFICANCE OF RESULTS Oncologists and psychiatrists should pay greater attention to the psychosocial and environmental problems of cancer patients and inquire about the presence of physical abuse in suspected cases. Medical staff should also know that early multidisciplinary interventions in addition to cancer treatments are needed for victims of physical abuse among cancer patients and that these interventions are necessary to improve compliance with treatment and proper decision making.

Conversion disorder with convulsion and motor deficit mimicking the adverse effects of high-dose Ara-C treatment in a posttransplant acute myeloid leukemia patient: a case report and review of the literature.

In this communication, we report an acute leukemia patient who developed conversion disorder mimicking the adverse effects of high-dose cytosine arabinoside (Ara-C) treatment after the patient received high-dose Ara-C treatment. A 21-year-old woman, with acute recurrent leukemia after bone marrow transplantation, received high-dose Ara-C treatment and 10 days later was referred for psychiatric consultation because of an abrupt onset of convulsion. On neurologic examination, she showed convulsion of all the limbs without loss of consciousness. All limbs looked paretic; however, tendon reflexes in all limbs were normal and pathological reflex was not recognized. When her hand was dropped onto her own face, it fell next to her face but not on her face. Laboratory data were unremarkable. She had no history of psychiatric illness or drug or alcohol abuse. The patient explained that she knew about the recurrence of her own leukemia and the news of the death of a close friend due to leukemia at the same time, which was a shocking event for her, focusing her attention on her own fears of dying from the same disease. Conversion disorder in cancer patients is not common; however, appropriate diagnosis is very important to avoid inappropriate examinations and treatments. In leukemia patients receiving chemotherapy, various kinds of signs and symptoms may develop due to the adverse effects of chemotherapy and/or infection. Therefore, conversion disorder might be overlooked and inappropriate treatment and examinations might be performed. Clinicians should consider conversion disorder in the differential diagnosis when patients develop unexplained neurological symptoms.

Brief psychotic disorder mimicking the symptoms of cerebrovascular attack evoked by symptoms that symbolized death in a patient with terminal stage stomach cancer: Case report and review of the literature

OBJECTIVE We report here a terminally ill patient with stomach cancer who developed a brief psychotic disorder mimicking cerebrovascular attack after a short episode of nasal bleeding. Close examination of the patient revealed that nasal bleeding was an event that symbolized deterioration of the general condition leading to death for the patient. METHODS A 77-year-old male, who was diagnosed as having stomach cancer and was receiving palliative care, presented with tremor and insomnia just after a short episode of nasal bleeding and showed reduced response to stimuli mimicking cerebrovascular attack. Laboratory data were unremarkable. The next day, catatonic behavior developed. He had no history of psychiatric illness or drug or alcohol abuse. After receiving haloperidol, psychiatric symptoms disappeared and he returned to the previous level of functioning within 3 days. The patient explained that he had seen a patient whose general condition deteriorated after nasal bleeding and regarded nasal bleeding as a symptom of deteriorating general condition leading to death and thereafter became afraid of the nasal bleeding. RESULTS AND SIGNIFICANCE OF RESULTS Although, nasal bleeding is common and usually not severe in medical settings, for the patient, it was an event that symbolized deterioration of the general condition leading to death. Brief psychotic disorder in cancer patients is rare in the literature, although patients receiving terminal care share various kinds of psychological burden. Medical staff in the palliative care unit should be aware of the psychological distress experienced by each patient and consider brief psychotic disorder as part of the differential diagnosis when patients show unexplained neurological-like and/or psychiatric symptoms.
