The incidence, magnitude, and duration of acute pain experienced by neurosurgical patients after various brain operations are not precisely known, because of a lack of well-designed clinical and epidemiological studies. We assessed these important pain variables in 37 consecutive patients who underwent various brain neurosurgical procedures. Postoperative pain was more common than generally assumed (60%). In two-thirds of the patients with postoperative pain, the intensity was moderate to severe. Pain most frequently occurred within the first 48 hours after surgery, but a significant number of patients endured pain for longer periods. Pain was predominantly superficial (86%), suggesting somatic rather than visceral origin and possibly involving pericranial muscles and soft tissues. Subtemporal and suboccipital surgical routes yielded the highest incidence of postoperative pain. Age and sex were significantly associated with the onset of pain, with female and younger patients reporting higher percentages of postoperative pain. Psychological Minnesota Multiphasic Personality Inventory profiles of patients with and without pain significantly differed on the Hypochondriasis scale, with patients without pain scoring unexpectedly higher than patients with pain. It is possible that hypochondriasis serves as a defense mechanism against pain, at least in some patients. Results of this pilot study indicate that postoperative pain after brain surgery is an important, although neglected, clinical problem, that deserves greater attention by surgical teams, to provide better and more appropriate treatment.

This study investigated the perceptual/cognitive abnormality model of hypochondriasis, which suggests that hypochondriacal patients amplify and misinterpret normal bodily sensations. The hypothesis was evaluated by assessing pain perception and stress reactivity in female hypochondriacal (N = 15) and female nonhypochondriacal control subjects (N = 15). Subjects completed self-report measures and participated in a laboratory stress reactivity assessment consisting of the cold pressor task and an imagery task. Hypochondriacal subjects exhibited a significant increase in heart rate during the cold pressor task and a significant drop in hand temperature relative to controls. Hand temperature remained lower among the hypochondriacal subjects after the cold pressor task was terminated. Hypochondriacal subjects terminated the cold pressor task more frequently, left their feet in the cold water bath a significantly shorter period of time, and rated the cold pressor task as significantly more unpleasant (although not more intense) relative to controls. Group differences were not observed in the imagery task. Of interest, hypochondriacal subjects' baseline heart rate was significantly lower than that of controls. Taken together, these data suggest that hypochondriacal behavior may be mediated, in part, by objective differences in physiological reactivity.

A 34-years male was admitted to our hospital with a hypochondria pain and low grade fever. Abdominal CT revealed an encapsulated 8 x 3 cm low density lesion on the surface of the liver (S5, S8) and multiple low density lesions of the spleen. The patient had already been treated with anti-tuberculous drugs for the past 7 months after being diagnosed as tuberculous pleuritis. Although echo-guided percutaneous needle biopsy was tried for the hepatic lesion, no special finding was obtained. Therefore a diagnostic laparotomy was performed and the hepatic lesion was resected. Abscess formation of the resected lesion was noted. Histopathology of the lesion revealed epithelioid granuloma, but microscopy, culture and PCR for tuberculosis revealed negative results. Abdominal CT, 3 weeks after surgery, revealed enlargement of the splenic lesion. Splenectomy was carried out to avoid splenic rupture. Multiple abscess of the resected spleen was noted. Pathological finding, Ziehl-Neelsen stain and PCR for tuberculosis confirmed the diagnosis of tubercular splenic and liver abscess. Although tubercular liver and splenic abscess are very rare recently, it should be included in the differential diagnosis of unknown hepatic and splenic lesions.

A retrospective study of 677 patients who underwent surgery for hepatic hidatidosis in the Department of Surgery A and B of the Hospital Miguel Servet in Zaragoza, Spain, over the last 21 years is presented. The frequency was analyzed in regards to sex, age, symptomatology, cyst data, surgical techniques performed and postoperative morbidity. The mean age of the patients was 39 years with the incidence being practically equal in both sexes. Dyspeptic symptoms (60%), hepatomegaly and/or palpable mass in the right hypochondria (58%) and pain (46%) were the most frequent clinical signs and symptoms observed. Radical surgery was performed in 21% of all the surgical treatments, while conservative surgery was undergone in 79%. Solitary cysts were most frequent (65.7%) with localization in the right hepatic lobe (65.4%). The most frequent postoperative complication was biliary fistula (72 cases). The rate of reintervention was 18% and operative mortality 1.6% with a mean hospitalization period of 25 days.

Since the exclusion of somatic causes is necessary for somatoform disorders (SMD) to be diagnosed, there is little information on the prevalence of such disorders in the community. As the method we have previously developed [general practitioners (GPs) with psychiatric training who interview samples representative of the general population] seemed to be appropriate to deal with the problem, we carried out a community survey focused on somatoform disorders. The prevalence rates of DSM-III-R somatoform disorders were studied in two wards of the city of Florence. In order to be representative of the general population, 673 subjects randomly selected were interviewed by their own GP. Four GPs, all with specific training in psychiatry, participated in the interviewing process. The 1-year prevalence figures were as follows: 0.7% body dysmorphic disorder; 4.5% hypochondriasis; 0.6% somatoform pain disorder; 0.3% conversion disorder; 0.7% somatization disorder; 13.8% undifferentiated somatoform disorder. No specific comorbidity was found between somatoform disorders and mood or anxiety disorders. Although the sample investigated was small, this study may be seen as one of the first in an area where knowledge is still scant. The prevalence rates of somatoform disorders were generally found to be slightly lower than expected.

A study was conducted to investigate chronic pain patterns in Vietnam veterans with posttraumatic stress disorder (PTSD). Combat veterans with PTSD completed standardized PTSD severity, pain, somatization, and depression measures. Of 129 consecutive out-patient combat veterans with PTSD, 80% reported chronic pain. In descending order were limb pain (83%), back pain (77%), torso pain (50%), and headache pain (32%). Compared to PTSD combat veterans without chronic pain, PTSD veterans who reported chronic pain reported significantly higher somatization as measured by the Minnesota Multiphasic Inventory 2 hypochondriasis and hysteria subscales. In the sample of 103 combat veterans with PTSD and chronic pain, MMPI 2 hypochondriasis scores and B PTSD symptoms (reexperiencing symptoms) were significantly related to pain disability, overall pain index, and current pain level MMPI 2 hypochondriasis and depression scores were also significantly related to percent body pain. These results are discussed in the context of current conceptualizations of PTSD.

The aim of this study was to find predictors of length of time on sick-leave and the change in sick-leave as a result of intervention. Many studies of back pain show that medical and psychosocial factors covary with length of sick-leave. The results are based on the questionnaire responses of 240 patients. A stepwise multiple regression showed that the significant predictors of number of sick-days the year after intervention were the number of sick-days before the intervention and also hypochondria. Significant predictors of sick-leave change were sleep disturbance and number of sick-days before intervention. A discriminant function analysis comparing a group that had decreased its sick-leave with one that had increased its sick-leave showed 7 predictors of increased sick-leave: high risk of somatisation; many children and family members living at home; a change in tasks at work owing to pain; brothers and sisters with longstanding pain problems; frequent pain, and sleep disturbance. It is important for physiotherapists to enquire about patients' earlier sick-leave patterns in order to identify risk factors for long-term disability among patients with back pain. Some of these factors have been identified in this study.

The Geriatric Depression Scale (GDS) is intended for easy measurement of symptoms of depression in elderly patients. The scale initially had 30 items but was reduced to a 15-item scale (GDS-15). This scale was translated into Swedish. However, five items were added: insomnia, anxiety, panic, aches and pain, and hypochondria. A total of 1002 elderly patients were rated by a research nurse using this scale. The results showed that 13.3% of the patients were considered to have affective disorders. The introduction of selective serotonin reuptake inhibitors has been of great importance for elderly patients, as these patients have difficulty in tolerating traditional tricyclic antidepressants. In a study of 133 elderly depressed patients, including those with somatic disorders and dementia, citalopram was tested. This drug provided significantly greater improvement than placebo. In another, inter-Nordic study, including 98 patients, citalopram was tested in patients with Alzheimer-type dementia. Depressed mood, and also other emotional disturbances, improved in these patients. Ratings have shown that in victims of Alzheimer-type dementia and vascular dementia, about 80% suffer from emotional disturbances. Drugs that influence both serotonin and noradrenaline metabolism have been introduced recently; these are of great interest in the treatment of elderly people.

The role of hypochondriasis in the attentional control of pain perception was investigated in 28 in-patients (12 women and 16 men) at a hospital for psychosomatic disorders, who had been classified into high- and low-hypochondriacal categories by means of the Illness Attitude Scales (IAS). The two groups did not differ in their basic pain sensitivity based on their heat pain thresholds. Attentional control was manipulated by a mental arithmetic task, resulting in one experimental condition with distraction and one without distraction. In both of the conditions, subjects rated the intensity and the unpleasantness of nonpainful and painful heat stimuli on visual analog scales (VAS). Distraction significantly reduced the perceived intensity and unpleasantness of the stimuli at painful levels but not at nonpainful levels. Contrary to our expectation, the individual level of hypochondriasis did not influence this result. Although distraction seemed to have a strong influence on pain perception, hypochondriasis as a symptom or a trait did not contribute to this effect.

It is generally recognized that psychological factors play an important role in chronic orofacial pain patients. This study analysed psychological profiles of chronic pain patients affected with temporomandibular disorders (TMD), by means of the Minnesota Multiphasic Personality Inventory (MMPI) test. Fifty consecutive TMD patients were examined and were then divided into two subgroups: 1. myofascial pain and 2. temporomandibular joint articular disorders. Sixty-two percent of the whole sample presented pathological MMPI scores. Both subgroups presented similar profiles with alteration of the neurotic triad (hypochondriasis, depression, hysteria), and pathological values of hypochondriasis and hysteria ("V" configuration). Since the personality profile did not differ between the two subgroups investigated, it was not dependent on the dysfunctional origin of the pathology (myalgia or primary TMJ pathology). Chronic TMD patients presented personality characteristics similar to those of other chronic pain patients according to the MMPI.
