Deliberate foreign body ingestion in patients with underlying mental illness: A retrospective multicentre study

OBJECTIVE

Deliberate foreign body ingestion (DFBI) is characterised by recurrent presentations among patients with mental health conditions, intellectual disabilities and in prisoners. We aimed to profile the characteristics and evaluate the care of such patients in this study.

METHODS

Adult patients with an endoscopic record of attempted foreign body retrieval between January 2013 and September 2020 were identified at three Australian hospitals. Those with a documented mental health diagnosis were included and their standard medical records reviewed. Presentation history, demographics, comorbidities and endoscopic findings were recorded and described.

RESULTS

A total of 166 admissions were accounted for by 35 patients, 2/3 of which had borderline personality disorder (BPD). Repetitive presentations occurred in more than half of the cohort. There was an increased trend of hospital admissions throughout the years. At least half of the cohort had a documented mental health review during their admission. An average of 3.3 (2.9) foreign bodies were ingested per single episode. Endoscopic intervention was performed in 76.5% of incidents. The combined Length of stay for all patients was 680 days.

CONCLUSION

Deliberate foreign body ingestion in mental health patients is a common, recurring and challenging problem that is increasing in frequency and requires collaborative research to further guide holistic management.

Identical and Nonidentical Twins: Risk and Factors Involved in Development of Islet Autoimmunity and Type 1 Diabetes

OBJECTIVE

There are variable reports of risk of concordance for progression to islet autoantibodies and type 1 diabetes in identical twins after one twin is diagnosed. We examined development of positive autoantibodies and type 1 diabetes and the effects of genetic factors and common environment on autoantibody positivity in identical twins, nonidentical twins, and full siblings.

RESEARCH DESIGN AND METHODS

Subjects from the TrialNet Pathway to Prevention Study (N = 48,026) were screened from 2004 to 2015 for islet autoantibodies (GAD antibody [GADA], insulinoma-associated antigen 2 [IA-2A], and autoantibodies against insulin [IAA]). Of these subjects, 17,226 (157 identical twins, 283 nonidentical twins, and 16,786 full siblings) were followed for autoantibody positivity or type 1 diabetes for a median of 2.1 years.

RESULTS

At screening, identical twins were more likely to have positive GADA, IA-2A, and IAA than nonidentical twins or full siblings (all P < 0.0001). Younger age, male sex, and genetic factors were significant factors for expression of IA-2A, IAA, one or more positive autoantibodies, and two or more positive autoantibodies (all P ≤ 0.03). Initially autoantibody-positive identical twins had a 69% risk of diabetes by 3 years compared with 1.5% for initially autoantibody-negative identical twins. In nonidentical twins, type 1 diabetes risk by 3 years was 72% for initially multiple autoantibody-positive, 13% for single autoantibody-positive, and 0% for initially autoantibody-negative nonidentical twins. Full siblings had a 3-year type 1 diabetes risk of 47% for multiple autoantibody-positive, 12% for single autoantibody-positive, and 0.5% for initially autoantibody-negative subjects.

CONCLUSIONS

Risk of type 1 diabetes at 3 years is high for initially multiple and single autoantibody-positive identical twins and multiple autoantibody-positive nonidentical twins. Genetic predisposition, age, and male sex are significant risk factors for development of positive autoantibodies in twins.

Atypical fractures on long term bisphosphonates therapy

Bisphosphonates reduce fractures risk in patients with osteoporosis. A new pattern of fractures is now being noted in patients on prolonged bisphosphonate therapy. We report a case of an atypical femoral fracture with preceding pain and highlight the characteristics of these fractures.

Effects of stress and relaxation on capsaicin-induced pain

A sizable body of research has been devoted to understanding the relationship between pain sensitivity and the psychological state of the individual. Considerable disagreement as to the direction of the association still exists. This study examines the effects of 2 experimental manipulations, cognitive/emotional stress and relaxation, on capsaicin-induced pain. Subjects were pretrained in relaxation and then randomized to experimental stress produced by a 20-minute Stroop test, relaxation (tape), or a control condition (neutral video), followed by a capsaicin injection in the forearm. Cardiovascular measures were taken at regular intervals, and cortisol, norepinephrine (NE), and self-reports of arousal (relaxation index) were taken immediately before and after the experimental task. The manipulation significantly interacted with sex to predict capsaicin-induced maximum pain. Women in the stress condition reported greater pain than both men in the stress condition and women in the relaxation condition. Pain was correlated negatively with task-induced changes in NE and cortisol and positively with self-reported arousal (decreased relaxation). However, separate analyses showed that some physiologic indexes of heightened arousal (increased blood pressure and NE) predicted lower pain only in men, whereas subjective increases in arousal predicted higher pain only in women. Multiple hierarchical regression analyses confirmed that physiologic and self-reported arousal predicted pain independently and in opposite directions, and a model including both accounted for 56% of the overall variance. These findings suggest that a unidimensional model of arousal may be insufficient to explain the effects of stress on pain and that these effects operate differently in men and women.

Effects of relaxation and stress on the capsaicin-induced local inflammatory response

OBJECTIVE

Although stress is known to modulate the inflammatory response, there has been little experimental examination of the effects of stress and stress reduction on inflammation in humans. In particular, the effects of stress and relaxation on neurogenic inflammation have been minimally studied. This study examines the effects of three experimental manipulations: mental stress, relaxation, and control on the local inflammatory response evoked by the intradermal injection of capsaicin, the active ingredient in chili peppers.

METHODS

Fifty subjects (28 men and 22 women) were pretrained in relaxation using an imagery-based relaxation tape and then randomized to experimental condition. Subjects participated in an evening reactivity session including 20 minutes of a stress (Stroop test), relaxation (tape), or control (video) manipulation, followed by a capsaicin injection in the forearm. Digitized flare measurements were taken for 1 hour postcapsaicin, and measurements of cardiovascular variables, cortisol, adrenocorticotrophic hormone, and norepinephrine were taken at regular intervals.

RESULTS

The size of the maximum capsaicin-induced flare was significantly smaller in the relaxation condition than in the stress or control conditions, which did not differ from each other. Increases in norepinephrine, heart rate, and systolic blood pressure during the experimental task, but not after capsaicin, significantly predicted size of maximum flare and total area under the curve of flare measurements.

CONCLUSIONS

These findings suggest that stress reduction may affect local inflammatory processes. Results are consistent with sympathetic modulation of the effects of relaxation on the flare response.

Adjunctive non-pharmacological analgesia for invasive medical procedures: a randomised trial

BACKGROUND

Non-pharmacological behavioural adjuncts have been suggested as efficient safe means in reducing discomfort and adverse effects during medical procedures. We tested this assumption for patients undergoing percutaneous vascular and renal procedures in a prospective, randomised, single-centre study.

METHODS

241 patients were randomised to receive intraoperatively standard care (n=79), structured attention (n=80), or self-hypnotic relaxation (n=82). All had access to patient-controlled intravenous analgesia with fentanyl and midazolam. Patients rated their pain and anxiety on 0-10 scales before, every 15 min during and after the procedures.

FINDINGS

Pain increased linearly with procedure time in the standard group (slope 0.09 in pain score/15 min, p<0.0001), and the attention group (slope 0.04/15 min; p=0.0425), but remained flat in the hypnosis group. Anxiety decreased over time in all three groups with slopes of -0.04 (standard), -0.07 (attention), and -0.11 (hypnosis). Drug use in the standard group (1.9 units) was significantly higher than in the attention and hypnosis groups (0.8 and 0.9 units, respectively). One hypnosis patient became haemodynamically unstable compared with ten attention patients (p=0.0041), and 12 standard patients (p=0.0009). Procedure times were significantly shorter in the hypnosis group (61 min) than in the standard group (78 min, p=0.0016) with procedure duration of the attention group in between (67 min).

INTERPRETATION

Structured attention and self-hypnotic relaxation proved beneficial during invasive medical procedures. Hypnosis had more pronounced effects on pain and anxiety reduction, and is superior, in that it also improves haemodynamic stability.

Challenges in geriatric oral health research methodology concerning caregivers of cognitively impaired elderly adults

Little is known about oral health care behaviors of community-dwelling, cognitively impaired elderly (CIE) persons. Few studies have been conducted regarding the actual provision of oral care for CIE persons or the attitudes and concerns about oral health among their caregivers. The CIE person's ability to perform self-care decreases over time, and the role of the caregiver in daily oral care becomes increasingly important. The purpose of this pilot study was to explore the attitudes toward oral health and identify related concerns among caregivers who care for community-dwelling CIE persons. Caregivers were surveyed by means of a self-administered, mailed questionnaire. To maintain confidentiality, an intermediary was used for recruitment and data collection. Overall, 148 caregivers were invited by an intermediary to participate in the survey; only 21 (14%) consented to participate and returned the questionnaire. This paper discusses some of the numerous methodological challenges identified when an attempt was made to survey care-givers' attitudes toward and barriers to providing oral care for a dependent CIE.

Ultrasound in the diagnosis and exclusion of intussusception

Intussusception is a major cause of intestinal obstruction in infancy and childhood. Improved results of treatment have followed the increased use of ultrasound imaging and pneumatic reduction. We prospectively studied the value of ultrasound in both the diagnosis and exclusion of intussusception in a peripheral paediatric unit over a four year period from October 1990 to October 1994. In all, 24 patients had a suspected clinical diagnosis of intussusception of which 19 had typical ultrasound findings. The male to female ratio was 8:11 and age at presentation ranged from 2 to 38 months (mean 11.4 months). There were no false negatives and 2 false positives giving a sensitivity to 100% and specificity of 89%. Thus no intussusception was missed by ultrasound examination. Enema reduction was successful in 76% of cases and factors associated with failure of enema reduction included passage of blood per rectum and symptoms for greater than 24 hours. We conclude that ultrasound should be used as a rapid and sensitive screening procedure in the diagnosis and exclusion.

Thyroid hormones and selenium status in breast cancer

Within a case-control study of postmenopausal breast cancer patients (n = 99) and matched healthy controls (n = 105), thyroid hormone levels were compared and correlated with toenail selenium concentrations. Plasma triiodothyronine (T3) was significantly lower in cases (1.4 +/- 0.4 nmol/l) than in controls (1.6 +/- 0.4 nmol/l), and a strong inverse relationship with breast cancer was observed with an odds ratio of 0.17 (95% CI = 0.08-0.36) in the highest compared with the lowest tertile of T3. Plasma thyroxine and thyroid-stimulating hormone concentrations were similar between cases and controls. Plasma T3 concentration was positively associated with toenail selenium in cases (age-adjusted regression coefficient = 0.049) and controls (age-adjusted regression coefficient = 0.036). Toenail selenium concentrations tended to be lower in cases than in controls, but the differences did not reach statistical significance. Although the disease process per se may explain the lower plasma T3 concentrations, it is also possible, inasmuch as these patients were in early-stage breast cancer, that selenium status may be influencing T3 levels via changes in the activity of the selenoenzyme type 1 iodothyronine deiodinase.

Desire for control, felt control, and stress inoculation training during dental treatment

Coping style research has typically assessed subjects' desire for a coping resource, but ignored whether subjects possess that resource. In this study 110 dental patients were categorized as to their desire for and feelings of control and were randomly assigned, just prior to dental treatment, to a 20-minute Stress Inoculation Training (SIT) session or a Filler condition. SIT significantly reduced pain and increased control only for patients who initially reported a high desire for control coupled with low perceived control. This finding supports the view that the discrepancy between high desire for control and low perceived control plays a causal role in the elevated distress and pain initially reported by patients with such control perceptions. These data indicate that consideration of patients' perceived coping resources as well as their coping preferences adds to our ability to predict reactions to stress reduction manipulations.

Emotional and sensory focus as mediators of dental pain among patients differing in desired and felt dental control

Giving patients instructions to focus on sensory (vs. emotional) stimuli during a root canal procedure significantly reduced self-reported pain, but only among patients who were classified as having strong desire for control and low felt control in dental situations. Among patients with low felt control and low desire for control, sensory-focus instructions produced greater pain reports than did emotion-focus instructions. Finally, high desire-low felt patients reported higher levels of expected pain before treatment than did other patient subgroups. These data suggested limiting conditions for H. Leventhal's (1982) theory of emotion and supported the idea that desire for control might moderate the effects of perceived control.

Breast tumour thymidine kinase levels and disease recurrence

Thymidine kinase (TK) exists in two forms, TK1 and TK2. TK levels and oestrogen receptor status (OR) were measured in tumours from 86 patients with operable breast cancer and the patients were monitored for recurrence over 24 months. During the monitored period, 13 patients showed recurrence. These patients also exhibited higher total TK levels per mg tumour (P < 0.01) and higher TK1 levels (P < 0.001) than those who did not show recurrence. TK1 levels relative to TK2 were significantly higher (P < 0.05) in OR-negative tumours (n = 29) than in OR-positive tumours (n = 57). OR-negative (n = 9) and OR-positive (n = 4) patients who recurred had significantly higher TK1 levels relative to TK2 than did those who not recur (n = 20 and n = 53, respectively). These preliminary results indicate that breast tumour TK levels may have value in determining prognosis.

Tobacco-related attitudes and counseling practices of Iowa dentists

Evidence suggests that dentists' efforts to encourage their patients to stop tobacco use can significantly decrease tobacco-related morbidity and mortality. This study identified attitudes and counseling practices of 1116 Iowa dentists and compared results of a subgroup (N = 55) surveyed in both 1983 and 1989 to note changes in their tobacco-related attitudes and practices. Although only 9% of the dentists from the statewide survey felt counseling their patients on tobacco use was inappropriate, 56% reported they did not routinely ask their new patients about tobacco use. With some frequency 90% of the dentists discussed negative health effects of tobacco, whereas only 64% advised their smokers to quit. In addition, fewer than half made special efforts with pregnant patients or those at high risk for heart disease. The vast majority reported seldom if ever using intervention tools such as pamphlets or referral to cessation programs. Data from the subgroup surveyed in 1983 and 1989 indicated few substantial changes in attitudes and counseling practices. Substantial discrepancies exist between dentists' attitudes and counseling practices. Well-designed programs are needed to help dentists select and implement appropriate interventions.

The effects of short-term social support from dentists on the stress experienced by parents of pediatric dental patients

Parents of pediatric dental patients were observed in a university clinic waiting room as they were greeted by student dentists. Soon after the dentist left with the child, the parents completed a series of scales assessing their perceived social support from the dentist, their anxiety and distress levels, and their confidence in the dentist. Regression analysis indicated that perceived social support from the dentist was associated negatively with parental distress regarding the dental treatment (beta = .-45, P < .01) and parental state anxiety (beta = .-37, P < .01). In addition, social support was associated positively with parent's confidence in the dentist beta = .54, P < .01). Possible mediational paths and clinical implications are discussed.

Development of radiolabelled albumin microspheres: a comparison of gamma-emitting radioisotopes of iodine (131I) and indium (111In/113mIn)

Biodegradable albumin microspheres have been prepared incorporating either 131I or 111In/111In. Using cDTPAA/albumin molar ratios of 1, 3 and 10, approx. 0.7, 2.1 and 7 molecules of DTPA could be coupled to an albumin molecule, labelling efficiency being constant over this range. Because 131I microspheres were more stable in plasma than the system labelled with radionuclides of indium it was selected for clinical evaluation: potential uses of this radiopharmaceutical are illustrated.

The analysis of 5-fluorouracil in human plasma by gas chromatography-negative ion chemical ionization mass spectrometry (GC-NICIMS) with stable isotope dilution

5-Fluorouracil (5-FU) was extracted from plasma and converted to its di-N-ditrifluoromethylbenzyl (DTFMBz) derivative by treatment with DTFMBzBr. Under negative ion chemical ionization (NICI) conditions the derivative yielded a mass spectrum in which most of the ion current was carried by the M(-)-DTFMBz ion (m/z 355). Selected ion monitoring enabled detection of this derivative in amounts less than 1 pg, and the practical limit of detection for 5-FU extracted from plasma was ca 400 pg ml-1. 5-FU was quantified by adding a fixed amount of [15N2]5-FU to samples of plasma before extraction, and comparing the ratio of the ions of m/z 355 and 357 against a calibration curve constructed over the concentration range under investigation. The method was used to measure the variation in the concentration of 5-FU with time during continuous infusion of the drug via three, different protocols in patients with hepatic tumour.

Some variables affecting dentists' assessment of patients' distress

Dental students estimated the pain distress and discomfort of their patients after patients received a Class II restoration (simple filing). Dentist's estimates of patient pain accounted for 36% of the variance in patient self-report responses. Dentist accuracy was significantly lower, however, for estimates of anxiety and distress. Dentist accuracy was unaffected by patient's degree of self-monitoring. There was a tendency for female dentists to demonstrate greater accuracy than male dentists, but this effect was nonsignificant. In addition, dentists' accuracy in assessing overall patient discomfort was significantly lower in that segment of the treatment procedure that was most stressful for the dentists. This article discusses theoretical explanations for this latter effect.

A comparison of two different T-grain films in rare-earth screens with a standard film-screen combination for intravenous pyelography and bone examinations

T-grain film is claimed to give significantly improved image quality, allowing the use of faster screens without loss of quality and thus reducing radiation dose. We tested this claim for two systems. In each case comparison was made with our usual screen-film combination, Agfa Curix RP1 film with Kodak Xomatic Regular screens (a nominally 200 speed system). The systems tested were Kodak TMatG in Kodak Lanex Medium screens (300 speed) and Agfa STG in Kodak Lanex Regular screens (400 speed). The Agfa STG-Lanex Regular system performed less well than the standard system for intravenous pyelograms (IVPs), bones and soft-tissue detail. Its speed advantage was not apparent below 70 kV. The Kodak TMatG-Lanex Medium system was better than the standard system for IVPs but not as good for bones. It gave virtually no speed advantage below 90 kV. Kodak T-grain film in a medium-speed, rare-earth screen was found to be better than the standard system for IVPs. Agfa T-grain film in a fast rare-earth screen was unsatisfactory for IVPs. Neither combination was as good as the standard system for bones.

Detection of splenosis: 99Tcm tin colloid scanning and computed transmission tomography compared

Ten patients who had been splenectomized for trauma between 1 and 11 years previously were studied by computed tomography (CT) and radionuclide scanning with 99Tcm tin colloid on the same day. Computed tomography detected splenic tissue in three patients. Radionuclide scanning detected splenic tissue in eight patients, including two cases of typical splenosis not identified by CT. Radionuclide scanning was found to be more sensitive in the detection of residual splenic tissue than CT.

Initial results of the use of a drug-interaction system

Dentists' knowledge about drug interactions, particularly in medically compromised older patients, may not be adequate. An on-line drug interaction system was tested for 4 months in a dental clinic to ascertain its usefulness in training students. Characteristics of high-risk patients are described, as well as opinions of users about the applicability of information presented and its relation to patient care. Approximately 3% of the patients seen were at risk of trauma from drug interactions, half of which were considered likely to occur. Implications of drug interaction data are also discussed in relation to treatment planning.

Simplified peripheral arteriography

Demonstration of both iliofemoral arteries and their peripheral run-off is usually performed either by the translumbar approach, or by placing a pigtail catheter at the aortic bifurcation. A modified version of the old retrograde pressure method, simply using a cannula in one femoral artery, is described. There was considerable saving in materials, personnel and time. This method may once again be the method of choice in a busy radiology department.

Exploration of the common bile duct--the relevance of the clinical picture and the importance of peroperative cholangiography

A series of 500 cholecystectomies performed over a 7-year period was reviewed retrospectively. The reliability of preoperative clinical features such as jaundice and pancreatitis was assessed in determining the presence of choledocholithiasis, and was found to be of limited value. Investigations such as intravenous cholangiography and liver function tests were found also to be inaccurate in the detection of common duct stones as was the appearance of the duct at operation. The usefulness of the peroperative cholangiogram in the detection of common duct stones that would otherwise have been overlooked is emphasized. Common duct stones would have remained undetected in 25 per cent of patients with choledocholithiasis. Despite the use of routine peroperative cholangiography common duct stones were overlooked in 11.25 per cent of patients who underwent exploration.

The insertion of prostheses at mastectomy for carcinoma of the breast--a preliminary report

There has been a move away from radical surgery for carcinoma of the breast to more conservative measures. However, even simple mastectomy causes considerable mutilation and is psychologically very upsetting for most patients. This has led to attempts at reconstruction of the breast and more recently to prostheses being inserted at the time of mastectomy (1). The early results of this procedure in 30 patients--the total experience of a general surgeon--are reported in this paper.

Incidence of sperm antibodies before and after vasectomy

Sperm-agglutinating antibodies were present in three (2-6%) of 117 fertile men and in 19 (33-9%) of 56 men who had been vasectomized. Twenty-four of the 56 vasectomized men had been studied before vasectomy; sperm-agglutinating antibodies were present in one (4-3%) compared with eight (33-3%) after vasectomy. No sperm-immobilizing antibodies were detected before vasectomy but were present in 10 (17-9%) of the 56 men after vasectomy.
