Comparative Epidemiology of Attempted and Fatal Suicide in a Defined Catchment Area in Israel

BACKGROUND

Both attempted and fatal suicides are important public health issues and the relationship between these behaviors has great relevance to clinical practice.

AIMS

To determine how the epidemiology of attempted and fatal suicide relate to each other over time.

METHOD

In an 18-year period consecutive admissions for suicide attempts (n = 4,645) to the emergency room of the central hospital of a well-defined catchment area were assessed using a structured interview. Data were compared with records of 425 fatal suicides from the same catchment area.

RESULTS

The relative rates of attempted and fatal suicide changed over time independent of both age and gender up to age 64. Rates of suicide and attempted suicide did not correlate over time in this age group. This was not true for the over 65 age group where attempted suicide and fatal suicide were significantly correlated over time in both men and women.

CONCLUSIONS

In subjects over 65 attempted suicide is highly associated with eventual suicide. This relationship is much less clear in younger age groups. Thus age of attempt is of great importance when considering the prognostic import of a suicide attempt.

Deliberate Self-Harm in Older Adults: A General Hospital Emergency Department Survey

BACKGROUND

Deliberate self-harm (DSH) increases the danger of future suicide death and the risk increases with age. Self-harm in older adults is often associated with greater suicidal intent and lethality.

OBJECTIVES

To investigate clinical and psychosocial variables of older patients (age ≥ 65 years) assessed due to DSH, compared with younger adults.

METHODS

Patients admitted to the Emergency Department following DSH during an 8 year period were included.

RESULTS

Of 1149 participants, 187 (16.6%) were older adults (age ≥ 65) and 962 (83.4%) were younger adults (< 65). The older adults reported DSH closer to mid-day (P < 0.01) and suffered more frequently from adjustment disorder and depression. Personality disorders and schizophrenia were less commonly diagnosed (P < 0.001). Prescription medication (sedatives and hypnotics) were a more frequent means (88% vs. 71%) of DSH among older patients. Younger patients with DSH used over-the-counter medications (21.9% vs. 6.4%) three times more than did the older patients (P < 0.01). Past DSH was significantly more frequent in younger adults. Following DSH the older patients were frequently admitted for further general hospitalization (P < 0.001).

CONCLUSIONS

Older adults with DSH are a unique group with different clinical characteristics. There is a need for targeted prevention strategies and education of caregivers regarding DSH in older adults.

Ultra-Low-Dose Buprenorphine as a Time-Limited Treatment for Severe Suicidal Ideation: A Randomized Controlled Trial

OBJECTIVE

Suicidal ideation and behavior currently have no quick-acting pharmacological treatments that are suitable for independent outpatient use. Suicidality is linked to mental pain, which is modulated by the separation distress system through endogenous opioids. The authors tested the efficacy and safety of very low dosages of sublingual buprenorphine as a time-limited treatment for severe suicidal ideation.

METHOD

This was a multisite randomized double-blind placebo-controlled trial of ultra-low-dose sublingual buprenorphine as an adjunctive treatment. Severely suicidal patients without substance abuse were randomly assigned to receive either buprenorphine or placebo (in a 2:1 ratio), in addition to their ongoing individual treatments. The primary outcome measure was change in suicidal ideation, as assessed by the Beck Suicide Ideation Scale at the end of each of 4 weeks of treatment.

RESULTS

Patients who received ultra-low-dose buprenorphine (initial dosage, 0.1 mg once or twice daily; mean final dosage=0.44 mg/day; N=40) had a greater reduction in Beck Suicide Ideation Scale scores than patients who received placebo (N=22), both after 2 weeks (mean difference -4.3, 95% CI=-8.5, -0.2) and after 4 weeks (mean difference=-7.1, 95% CI=-12.0, -2.3). Concurrent use of antidepressants and a diagnosis of borderline personality disorder did not affect the response to buprenorphine. No withdrawal symptoms were reported after treatment discontinuation at the end of the trial.

CONCLUSIONS

The time-limited, short-term use of very low dosages of sublingual buprenorphine was associated with decreased suicidal ideation in severely suicidal patients without substance abuse. Further research is needed to establish the efficacy, safety, dosing, and appropriate patient populations for this experimental treatment.

Treatment of Hypertension With Thiazides: Benefit or Damage?Effect of Low- and High-Dose Thiazide Diuretics on Arterial Elasticity and Metabolic Parameters in Hypertensive Patients With and Without Glucose Intolerance

Thiazide diuretics may cause multiple metabolic abnormalities. The authors investigated the effects of varying doses of hydrochlorothiazide (HCTZ) on arterial elasticity and metabolic parameters in patients with hypertension (HTN), HTN and impaired fasting glucose (HTN+IFG), and HTN and type 2 diabetes mellitus (HTN+DM). The patients received low and high doses of HCTZ. Systolic and diastolic blood pressures declined significantly during the first 3 months in all patients, but no additional decrease was seen following the increase in HCTZ dose. In HTN, large artery elasticity index and small artery elasticity increased during the study. In HTN+IFG, large artery elasticity index increased without improvement in small artery elasticity index. In HTN+DM, both large artery elasticity index and small artery elasticity index did not improve during follow-up. Low-dose HCTZ improves arterial elasticity in hypertensive patients, but this effect is diminished with concomitant DM or IFG. The HCTZ dose increase worsened parameters of glucose metabolism and did not further decrease blood pressure or improve arterial elasticity.

Perceived parental care and control among Israeli female adolescents presenting to emergency rooms after self-poisoning

Levels of perceived parental care and control among 24 female Israeli adolescents presenting at emergency rooms after a self-poisoning act of low lethality were compared to those found among 23 non-self-harming, community controls. Adolescents' perceived levels of parental care and control were measured via both adolescents' self-report and independent objective ratings of adolescents' unconstrained descriptions of their parents. Adolescents also completed a standardized psychological symptom checklist. Data from both measurement perspectives indicated that adolescents evidencing self-poisoning behavior perceived their mothers as less caring and more controlling--a parenting style characterized as "affectionless control"--than did the comparison group. Independent ratings of adolescents' descriptions of their parents suggested that those exhibiting self-poisoning also perceived their fathers as less caring. These effects were not moderated by level of psychological symptoms. The findings are consistent with those from previous research showing an association between perceived parental care and control and various self-harming behaviors among adolescents, and highlight the need for research on the potential clinical utility of employing family-based, attachment-promoting psychosocial interventions with this population.

Crossover assessment of serum bactericidal activity of grepafloxacin, ofloxacin and clarithromycin against respiratory pathogens after oral administration to healthy volunteers

Serum bactericidal activity was studied in a crossover manner in 10 volunteers, after 2-day administration of grepafloxacin 600 mg qd, ofloxacin 400 mg bid and clarithromycin 500 mg bid. Bactericidal activity against clinical isolates of Streptococcus pneumoniae, Haemophilus influenzae, Moraxella catarrhalis and Klebsiella pneumoniae, was estimated using a standardized microdilution method. Grepafloxacin was highly active against Gram-negative organisms and adequate against pneumococci (mean, 1:13.3). Clarithromycin was very active against both penicillin-susceptible and penicillin-partially-resistant S. pneumoniae (1:102.5) but had poor activity against H. influenzae (1:3.1). Minor adverse effects were commonly associated with grepafloxacin.

[First experiences in non-enhanced spiral computed tomography for diagnosis of acute flank pain]

Acute flank pain is commonly encountered in the emergency department, and often requires imaging to establish its cause. For decades intravenous urography and sonography have been the primary media for evaluating flank pain. Recently, noncontrast spiral CT (NCSCT) has been shown to be accurate and highly successful in diagnosing cause in such cases. We evaluated its use in the diagnosis of acute flank pain. During a 7-month period, 147 such cases had NCSCT imaging immediately after initial evaluation in the emergency department. Using a spiral CT scan without oral or i.v. contrast media, 109 of 147 cases were found to have ureteral stones, and 34 others to have other urological conditions unrelated to the cause of pain; 38 CT scans were negative for ureterolithiasis and in 14 non-urological disease was diagnosed. NCSCT is a valuable diagnostic technique for patients in the emergency department with flank pain. It rapidly and accurately detects ureteral stones causing renal colic and also detects extra-urinary causes of acute flank pain.

Comparison of ex-vivo serum bactericidal activity of cefepime, ceftazidime and cloxacillin against Staphylococcus aureus

Cefepime (1 g), ceftazidime (1 g), and cloxacillin (2 g) were administered intravenously to 10 volunteers each. After infusion of a single dose over 30 min, blood samples were obtained at 0.5, 1, 2, 3, 4, 5, 6, 8, 10, and 12 h (for ceftazidime at 0.5 and 4 h) after dosing. Drug levels were determined by the bioassay method. Serum bactericidal activity against five clinical isolates of cloxacillin-susceptible Staphylococcus aureus were determined by the microdilution method according to the National Committee for Clinical Laboratory Standards guidelines. The mean peak serum level was 76.88 +/- 24.71 mg/L for cefepime, 42.8 +/- 15.98 mL/L for ceftazidime, and 92.81 +/- 24.7 mg/L for cloxacillin. Concentrations of cefepime were detected during the whole testing period (mean trough level, 1.43 +/- 0.9 mg/L at 12 h), whereas concentrations of cloxacillin were measurable up to 5 h after administration (mean trough level, 0.90 +/- 0.97 mg/L). The mean peak reciprocal bactericidal titers were 29.41 for cefepime, 5.6 for ceftazidime, and 377 for cloxacillin. Effective bactericidal titers were detected as long as 5 h for cefepime (approximately 40% of the dosing interval) and 3 h for cloxacillin (at least 50% of the dosing interval). For ceftazidime, serum bactericidal activity was markedly lower compared with that of cefepime. Although cefepime has demonstrated an improved antistaphylococcal bactericidal activity compared with ceftazidime, it was somewhat lower than that of cloxacillin.

Serum bactericidal activity of newer oral cephalosporins in healthy volunteers

The serum bactericidal activity of three oral cephalosporins was studied in 12 volunteers, after administration of single doses of cefuroxime axetil 250 mg, cefixime 200 mg, cefixime 400 mg and cefetamet pivoxil 500 mg. Serum bactericidal activity against clinical isolates of Streptococcus pyogenes, Streptococcus pneumoniae, Haemophilus influenzae and Klebsiella pneumoniae was measured by a standardized microdilution method. Cefuroxime axetil demonstrated the best bactericidal activity against Gram-positive organisms and cefixime was the most bactericidal against Gram-negative bacteria.

Perception of physical pain in accident and suicide attempt patients: self-preservation vs self-destruction

The perception of physical pain and its relationship to psychological variables were examined in emergency-room (ER) patients who were admitted following suicide attempts or accident injuries, and in a control group of community subjects. Two pain measures, involving electric shocks, were administered to the subjects. Psychological variables included hardiness, body image, body satisfaction feelings about the body, stressful events, anxiety and depression. Suicidal subjects endured the highest number of shocks, scored lowest on the appraisal of pain, and scored lowest on psychological hardiness. Moreover, it was found that, among the suicidal subjects, the more negative the scores of psychological variables, the higher the endurance of pain. In accident victim subjects, the relationships were exactly opposite. These results were interpreted as reflecting two different core attitudes towards life under stressful circumstances: a life-destroying tendency in the suicidal subjects vs. a life-preserving tendency in the accident-victim subjects. These two core attitudes indicate different modes of defense: defensive detachment in the suicidal patients and avoidance of stress in the accident victims.

Tolerance for physical pain in suicidal subjects

This study investigated the tolerance for physical pain in suicidal subjects. Suicidal, psychiatric nonsuicidal, and normal young males and females were administered pain measures including electric shocks, appraisal of shocks, and a measure of thermal pain. Additional study variables included diagnosis, past suicide attempts, severity of suicidal intent, and length of hospitalization. Suicidal individuals showed higher tolerance for pain and appraised the pain as less intense than the other groups, regardless of diagnosis, length of hospitalization, and motivation to participate in the study. These findings were explained as a result of dissociative processes inherent in the development of suicidal tendencies and in terms of pain management strategies.

Carriage of methicillin-resistant Staphylococcus aureus by non-hospitalized subjects in Israel

The prevalence of methicillin-resistant Staphylococcus aureus (MRSA) in the anterior nares and axilla was studied in 920 non-hospitalized subjects: 350 drug addicts, 350 individuals presenting at a hospital emergency room for various reasons, and 220 hospital health care workers. S. aureus was isolated from 105 (11.4%) subjects, in six (6.3%) of whom the isolates were methicillin-resistant. The isolation rate of the organism and the prevalence of resistant strains in the different subgroups were, respectively: drug-addicts, n = 32 (9.1%), n = 2 (6.9%); emergency room patients, n = 36 (10.2%), n = 1 (3.2%); and hospital health care workers, n = 37 (16.8%), n = 3 (8.5%). Our findings suggest that MRSA remains uncommon in the community, while the prevalence of S. aureus carriage (including methicillin-resistant strains) in hospital personnel is quite similar in divergent geographical areas.

[Renal colic and renal calculus]

A positive diagnosis of urinary stone was made in 183 of 407 patients (44.9%) with renal colic seen in the emergency room. 182 (44.7%) had normal intravenous pyelograms, 26 (6.4%) had evidence of dilatation of the urinary system, possibly due to the passage of a stone, and 16 (3.9%) had other pathological urinary conditions, such as double collecting system or cysts. Stones were located in the upper urinary tract in 28.4%, in the midureter in 21.9%, and in the lower ureter in 49.7%. There was a statistically significant correlation between recurrent episodes of left-sided renal colic, erythrocytes in the urine and the presence of a stone in the urinary tract. No ethnic differences were found, nor was there a difference in the rates of stones found in those who were hospitalized and in those who were not.

Successful treatment of insulin lipoatrophy. A case report

Widespread subcutaneous lipoatrophy developed in a nineteen year old female diabetic using subcutaneous bovine NPH insulin. Neither rotation of the injection site nor injection of the same insulin into the atrophic areas affected the lesions. Replacement of the bovine insulin by a porcine preparation given by deep intramuscular injection into the center of the atrophic areas resulted in disappearance of the lesions within a short time.

Hepatomegaly due to self-induced hyperinsulinism

Repeated hypoglycaemic attacks, associated with transient hepatomegaly, in a 12-year-old insulin-dependent diabetic girl continued despite reduction in dose and, later, complete discontinuance of insulin. The attacks ceased while she was in hospital, necessitating reinstitution of insulin. The hepatomegaly resolved when surreptitious additional insulin injections were discovered and stopped. Hepatomegaly in diabetics should arouse suspicion of overdosage with insulin.

Pulmonary alveolar proteinosis associated with fanconi's anemia

A 16-year old patient with Fanconi's anemia developed pre-leukemia and pulmonary infiltration which was found upon autopsy to be pulmonary alveolar proteinosis. The question whether the pulmonary alveolar proteinosis was due to the marked leukopenia and an eventual defective phagocytic ability of the leukocytes is raised.
