The Ekbom's syndrome, also known as delirium of parasitic infestation, acarophobia, delusional parasitosis, psychogenic parasitosis, is a disease of rare occurrence. Generally it is characterized by the firm conviction of the patients to be infected by worms that come out of the skin, usually from the scalp or even from the mouth, from the eyes or from the genital region. Most of the patients are elderly and female, and with frequent social isolation. Some cases are associated with organic diseases as hyperthyroidism, diabetes, cortical lesion, intoxication by medicines. To our knowledge the association between delusional parasitosis with spasmodic torticollis was not described in literature. We report the case of a 72-year-old-woman with delusional parasitosis associated with spasmodic torticollis.

Weight gain is a well-known complication of antipsychotic therapy, especially when using newer atypical antipsychotic agents. In addition to the risk of medical comorbidities associated with weight gain, such as diabetes mellitus and cardiovascular disease, a further risk of antipsychotic-induced weight gain is that patients may resort to over-the-counter preparations to aid in weight loss. We report on a case in which a patient with schizophrenia began using Metabolife, an herbal preparation containing ephedra, for weight reduction and subsequently developed an exacerbation of his psychosis with superimposed delirium. We mention several relatively safe alternatives to herbal supplements for weight loss, as well as emphasize the need for clinicians to educate their patients regarding the potential risks of over-the-counter weight loss agents.

Physical and mental illnesses commonly occur together. The quality of physical care in institutions for mental health in the Netherlands is not guaranteed. The cases of a 63-year-old woman with a schizoaffective disorder and diabetes mellitus who became delirious after surgery and a 76-year-old suicidal man with a psychotic disorder due to hydrocobalamine deficiency after major heart surgery show that the so-called medical-psychiatric unit, which is a part of the Psychiatric Department of a general hospital, may have several advantages in the treatment of combined physical and mental disorders. Both patients were admitted to such a unit. In this way, the internist of the first patient could continue to treat her and she could be treated with an infusion, urinary catheter and gastric intubation; in addition, laboratory investigations could be performed. The second patient, whose safety required primary attention, could also be treated for his somatic disorders and a delirium could be ruled out. His family was assisted in recovering from their traumatic life experience caused by his suicide attempt.

The authors experienced 55 cases of anesthetic management in 52 elderly surgical patients, 14 men and 38 women, aged 90 to 101 years with an average of 92.1 +/- 2.1 years for the past ten years. Surgical procedures included 38 cases of orthopedic, 14 cases of general surgical and 3 cases of ophthalmic operations. Thirteen cases out of them were emergency. General, epidural, spinal, and local anesthesia were applied in 34 cases, 18 cases, 2 cases, and one case out of these elderly patients, respectively. These general anesthesia consisted of total intravenous anesthesia with propopol, fentanyl and ketamine in 27 cases, sevoflurane with nitrous oxide in 4 cases, isoflurane with nitrous oxide or air in 2 cases, and thiopental anesthesia in one case. The elderly patients had past history of heart disease, dementia, hypertension, cerebral infarction/hemorrhage, diabetes mellitus and others. Their preoperative examinations revealed anemia, hypoproteinemia, renal hypofunction, serum electrolytes imbalance, and others. Vasopessors were given to 42% of the patients during anesthesia and surgery. Their postoperative complications included myocardial infarction, paroxysmal atrial fibrillation, hypotension following anemia, transient hemiparesis, delirium and so on. Two patients developed myocardial infarction postoperatively and died thereafter. The authors suggest that appropriate anesthetic management for elderly patients aged 90 years or older requires proper preoperative evaluation, sufficient vigilance of hemodynamics with direct arterial pressure measurement, reliable preparation of medical agents, and awareness of impairment of circulatory function and others by aging.

Diabetes mellitus is an established risk factor related to significant morbidity and mortality after coronary artery bypass grafting. Data on 9682 patients undergoing coronary artery bypass grafting either with (n=8917) or without cardiopulmonary bypass (off-pump coronary artery bypass grafting; n=765) were subjected to an univariate analysis to identify potential associations between diabetes mellitus and 26 a priori selected perioperative outcome variables. Those having a significant association with diabetes were then subjected to a stepwise logistic regression model to identify the impact of diabetes as compared to additional 22 different a priori chosen patient related risk factors and treatment variables. Prevalence of outcome variables independently associated with diabetes has been determined in the subgroup of diabetics undergoing coronary artery bypass grafting with cardiopulmonary bypass or off-pump coronary artery bypass grafting surgery to evaluate the effect of avoiding cardiopulmonary bypass on perioperative patient outcome. Diabetes mellitus was defined as glucose intolerance either treated dietary, with oral hypoglycemics or with insulin. According to this definition of diabetes mellitus we found an overall prevalence of 37.1% (coronary artery bypass grafting with cardiopulmonary bypass: 37.5%; off-pump coronary artery bypass grafting: 32.5%). Eleven outcome variables having a significant association with diabetes were identified. Diabetes could be identified as an independent predictor of postoperative delirium, renal dysfunction and respiratory insufficiency. Prevalence of these three variables was lower in diabetics undergoing off-pump coronary artery bypass grafting as in those undergoing coronary artery bypass grafting with cardiopulmonary bypass surgery reaching statistical significance with regard to postoperative delirium and respiratory insufficiency. In conclusion, diabetes mellitus is a significant independent predictor for three postoperative outcome variables in coronary artery bypass surgery. Avoiding cardiopulmonary bypass in diabetics seems to have a beneficial effect.

To determine whether urine color, as measured by a color chart, might be a valid indicator of hydration status in frail nursing home residents, this study tested the associations between urine color and urine specific gravity. This is a descriptive correlational study set in seven nursing homes in eastern Iowa. Ninety-eight nursing home residents > or =65 years of age participated. Exclusion criteria for the study included: unstable congestive heart failure or diabetes, documented renal disease, hyponatremia (serum sodium <135 meq/L), terminal illness, acutely confused/delirious or urinary tract infection at baseline, and gastrostomy-tube dependence. Weekly urine specimens were collected. Ucol was measured first, using a urine color chart. Usg was determined using the Chemstrip Mini UA Urine Analyzer. Week-by-week Spearman rank order correlations between urine color and specific gravity for the total sample (n=98) ranged from r(s) = 0.3 - 0.7, p < .01; the PROC mixed model was significant, p < .01. In subgroup analyses (n=78), all females (r(s) = 0.67, p = .01) and both males (r(s) = 0.53, p = .01) and females (r(s) = 0.72, p =.01) with adequate renal function (Cockcroft-Gault estimated creatinine clearance [CrCl] values of > or =50 ml/min) had significant associations between average urine color and average Usg. Females with mild renal impairment (CrCl between 30 and 50 ml/min) also had significant associations between Ucol and Usg (r(s) = .64, p < .01). Ucol averaged over several individual readings offers another tool in assessing hydration status in Caucasian nursing home residents with adequate renal function measures by estimated CrCl values.

Falls occur commonly in older persons and are the seventh leading cause of death. Falls are associated with functional deterioration and "fear of falling". Falls can be due to extrinsic factors such as poor lighting, throw rugs and other environmental hazards. Intrinsic causes of falls include physiological changes associated with aging, orthostatic hypotension, many medications, delirium, anemia, diabetes mellitus, Parkinson's disease, depression, cognitive impairment, syncope, partial complex seizures and vitamin D deficiency. Management of falls requires a multidisciplinary approach with a home assessment and modification where appropriate, a careful geriatric assessment, exercise programs focusing on balance, resistance and endurance exercise and adequate vitamin D replacement. All fallers should be assessed and treated for osteoporosis. The complexities of the causes and management of falls, make persons with frequent falls an ideal person to be referred for a geriatric consult.

We aimed to identify fall incidence, predictors and characteristics and to investigate hospitalization outcomes for elderly inpatients. In 340 men and 280 women consecutively admitted to a Acute Geriatric Ward of a University Hospital the following variables were evaluated: demographics, clinical history, main disease responsible for hospitalization, comorbidity (cumulative illness rating scale: CIRS 1 and 2) gait and balance deficit (Tinetti's scales), cognition/function (short portable mental status questionnaire: SPMSQ); activities of daily living: ADL; instrumental activities of daily living: IADL; delirium (confusion assessment method: CAM), drugs administered during hospitalization. Overall 80 falls occurred in 70 patients. The incidence rate of falls was of 6.0 per 1000 patient-days with 2.0 falls per bed/year. Age (relative risk=RR=1.050; 95% confidence interval=CI=1.013-1.087), delirium (RR=3.577; 95% CI 1.096-11.672), diabetes (RR=5.913; 95% CI 1.693-20.644), balance deficit (RR=0.914; 95% CI 0.861-0.970) and polypharmacy (RR=1.226; 95% CI 1.122-1.340) were independently predictive of falling. Fallers had a prolonged length of stay (LOS) (35.5+/-47.8 days vs. 23.2+/-27.2; p=0.01) and more frequent nursing home placements (12.9% vs.5.6%; p<0.005). The knowledge of falling predictors might help in planning specific preventive strategies to improve the patients' global health status and to reduce the costs of medical care.

Postoperative delirium and its risk factors had been widely reported in several kinds of surgeries; however, there is only one known article relative to postoperative delirium in spinal surgery. We retrospectively examined the incidence of postoperative delirium and the probable risk factors in patients undergoing spinal surgery in our hospital, with the same aged non-delirium patients as controls, over a 6-month period. Studies about postoperative delirium were reviewed and referenced for variable factors collecting in our study. T tests, chi(2) test and logistic regression analysis were performed to evaluate the various factors related to postoperative delirium. A total of 18 patients (3.3%), all of them were aged 54 years or older, had postoperative delirium after surgery. Patients without postoperative delirium aged 54 years or older served as the control group. The percentage of patients older than 65 years (P = 0.003), with comorbid diseases such as diabetes mellitus (P = 0.042) or central nervous system disorders (P = 0.013), with a surgical history (P = 0.028) in delirium group was larger than the control group. The absolute number of medications being taken before the operation in the delirium patients was also more than the control group (P = 0.000). The percentage of patients transfused with 800 mL or more blood was also larger (P = 0.024) in delirium group was larger than the control group. Logistic regression analysis showed that central nervous system disorder (OR 6.480), surgical history (OR 3.499), age older than 65 years (OR 3.390), diabetes mellitus (OR 2.981), transfused 800 mL or more blood (OR 2.537), and hemoglobin less than 100 g/L (OR 0.281) were significantly related to the occurrence postoperative delirium. Our findings suggest that postoperative delirium in spinal surgery can also occurred in younger patients and with an acceptable incidence in total. The risk for postoperative delirium is multifactorial. More prospective research is necessary in order to evaluate these and other risk factors in greater detail.

The aim of this retrospective study is to examine the feasibility and safety of laparoscopic colorectal resection for colorectal malignancies to determine "high-risk" patients. In our classification, 3 minor criteria including patients over 70 years of age, body mass index over 30 m/kg, and cigarette smoking and 5 major criteria including cardiac, pulmonary, renal, liver disease, and diabetes mellitus were selected to determine a high-risk group. Patients carrying 1 minor and 1 major criteria were classified as the high-risk group. Concerning patients and operations, hemodynamic values (mean arterial systolic and diastolic pressures and heart rates), oxygen saturations, end-expiratory carbon dioxide levels, respiratory mechanics (dynamic compliance, peak inspiratory pressure, airway resistance) were analyzed. Cardiovascular system (myocardial infarction, arrhythmia, hypertension), pulmonary system (respiratory insufficiency), digestive system (anastomotic leak, fistula, and paralytic ileus), fever, thrombophlebitis, urinary infections, wound infections, and central nervous system (delirium and cerebrovascular accident) were also investigated. A total number of 85 high-risk patients were included in the study. Gastrointestinal leaks in 2.3%, fistula in 1.1%, ileus in 3.5%, postoperative bleeding in 2.3%, postoperative fever in 5.8%, wound infection in 5.8%, and cerebrovascular accidents in 1.1% of patients were detected. The lowest values of hemodynamic and respiratory mechanics were observed at the induction of pneumoperitoneum and in this period the compliance and mean arterial pressure were determined to be 36+/-14 mm Hg and 84+/-14 mm Hg, respectively. No mortalities occurred. In experienced hands, laparoscopic colorectal resection can be performed safely for "high-risk" surgical patients.
