Two episodes of ventriculoperitoneal shunt migration in a patient with idiopathic intracranial hypertension.

Introduction. Ventriculoperitoneal shunts are often placed as treatment for refractory idiopathic intracranial hypertension. Dislodgement and migration of the distal portion of the shunt are more common in obese patients and can be difficult to detect. We report the case of a woman with two separate episodes of shunt migration into her abdominal wall. Case Presentation. We report a case of a 37-year-old female with history of obesity eventually diagnosed with idiopathic intracranial hypertension (IIH) as the cause. She failed outpatient therapy and, through neurosurgery, had a VP shunt placed for symptom control. She had subsequent development of worsened symptoms that were found to be due to shunt migration. This happened not once but twice to the same patient. Conclusion. Shunt dislodgement, migration, and subsequent failure are common in obese patients who have shunts placed for IIH. The medical provider should maintain a high index of suspicion for shunt malfunction in these patients, particularly because clinical evaluation may be challenging due to habitus.

The reliability of cardiac haemodilution as a diagnostic test of drowning.

The diagnosis of drowning is one of the most challenging problems in forensic pathology. The estimation cardiac haemodilution is a simple method, but its use is limited by its lack of specificity and sensitivity. We have studied the limitations of this method and have defined the circumstances in which such a technique can be used.

Treatment of opiate withdrawal on entry to prison.

Forty-nine opiate-dependent persons entering remand prison were treated with methadone over 5-10 days in decreasing doses according to standard practice of the prison medical service. The prisoners were mainly young, unmarried men with an average of 5 years regular opiate use and an average of four previous imprisonments; 45% were known to be HIV infected, although routine testing was not carried out. Ten were on methadone maintenance prior to imprisonment. Urine analysis on entry detected an average of three psychoactive substances, principally opiates, benzodiazepines and cannabis. Prescribed starting doses of methadone were not correlated to independently assessed withdrawal severity. Starting doses were related to prisoners' requests and to their age. Withdrawal severity decreased after 4 days treatment but symptom relief was incomplete. Treating withdrawal symptoms on entry to prison poses unsolved ethical and practical problems.

Morphine in postmortem blood: its importance for the diagnosis of deaths associated with opiate addiction.

This article describes an analytical method for the determination of morphine, the active metabolite of heroin, in post-mortem blood by HPLC with electrochemical detection. An extraction technique allowing the determination of free and total morphine (free morphine + morphine glucuronide) was used. Blood morphine levels in postmortem cases are reported and the ratio of free to total morphine was measured in 52 cases obtained at autopsy. The importance of this ratio is discussed in relation to the circumstances of the death.

[Toxicomania: death beyond risk. Analysis of cause-of-death in drug addicts]. / Toxicomanie: la mort au-delà du risque. Analyse des causes de décès chez le toxicomane.

Violent deaths are of considerable importance among young adults, since they account for half the deaths in this age group (average age 26.4 years). Suicide and accidents (both categories including drug overdoses) are the most frequent categories of deaths from non-natural causes, while in the USA deaths by homicide are also of considerable importance. Current repressive policies have not brought the problem of drug addiction under control. Each year deaths by overdose among drug abusers occur. Nevertheless, 40% of deaths among drug addicts are from other causes, principally accidents and suicides. In the near future, AIDS may well account for the majority of deaths among drug addicts, thus adding to the mortality from overdose, both accidental and suicidal. Has the time come to reconsider the problem of drug abuse and to find radical solutions which would previously have been unthinkable?

Changes in lipoproteins induced by the remnant kidney tissue or binephrectomy in chronic uremic patients treated by hemodialysis.

The role of the remmant kidney tissue in uremic patients undergoing hemodialysis treatment has rarely been considered to influence the changes in lipoprotein and lipid metabolism. Twenty hemodialyzed patients with remnant kidneys and 11 anephric patients were studied to examine whether the presence or the absence of remnant kidney leads to qualitative or quantitative changes of the lipids and lipoproteins. Anephric patients showed a significantly higher triglyceride level, 3.66 +/- 0.49 (SEM) mmol/L v 2.34 +/- 0.09 mmol/L in patients with remnant kidneys (P less than .01), higher very-low-density lipoprotein (VLDL) triglycerides, 1.24 +/- 0.30 mmol/L v 0.69 +/- 0.09 (P less than .04), and higher HDL-triglycerides, 1.22 +/- 0.29 mmol/L v 0.66 +/- 0.09 mmol/L (P less than .04). APO-AI was significantly decreased in anephric patients, 95.2 +/- 13.3 mg/dL v 129.7 +/- 6.02 mg/dL in patients with remnant kidneys (P less than .01). APO-B was similar in both groups. All APO-C and APO-E were significantly lower in anephric patients, APO-CI 6.13 +/- 0.87 mg/dL v 8.47 +/- 0.42 mg/dL in patients with remnant kidneys (P less than .01), APO CII 1.00 +/- 0.01 mg/dL v 10.0 +/- 0.01 mg/dL (P less than .0001), APO-CIII 10.12 +/- 1.43 mg/dL v 26.0 +/- 2.86 mg/dL (P less than .0005), and APO-E 8.0 +/- 0.02 mg/dL v 12.0 +/- 0.01 mg/dL (P less than .03). These results point out important differences between women and men. In women binephrectomy promotes a decreased concentration of all APO-C but has no influence on APO-AI concentration.(ABSTRACT TRUNCATED AT 250 WORDS)

[The drug addict in prison: Medical response and its limitations]. / Le toxicomane en milieu carcéral: la réponse médicale et ses limites.

Over the past twenty years, the proportion of drug dependent inmates has risen dramatically in the prisons of Western Europe. In the Geneva romand prison, where about 30% of entries present problems of opiate abuse and dependence, treatment of withdrawal symptoms with decreasing doses of methadone over a period of 5-10 days has been available since 1974. The rational of this treatment policy is to limit immediately disabling symptoms during the stressful period following imprisonment, when the prisoner has to make important decisions concerning the criminal proceedings in which he is involved. On the other hand, methadone maintenance treatment is not provided within the prison, even for patients on methadone maintenance programs prior to imprisonment. This paper traces the evolution of withdrawal treatments with methadone over the period 1974-1987 in relation to the total number of entries, the age and sex distribution. During the three year period 1985-1987, we found that 6% of prisoners had received at least one course of withdrawal treatment. Many drug dependent individuals have repeated arrests: we found that 27% of those receiving withdrawal treatment in a three year period had more than one treatment. The frequency of suicidal gestures (including wrist slashing) and suicide was not greater during the withdrawal phase than at other times. A number of therapeutic approaches to opiate withdrawal now exist. No method seems clearly to be the treatment of choice within the prison environment. Arrest and imprisonment imply enforced withdrawal in a context of conflict and stress without the possibility of close medical supervision or psychological support.(ABSTRACT TRUNCATED AT 250 WORDS)
