The impact on new-onset stress and PTSD in relatives of critically ill patients explored by diaries study (The "INSPIRED" study)

BACKGROUND

There is rising prevalence of post-traumatic-stress-disorder (PTSD) in patients and their relatives after ICU discharge. The impact of ICU diaries on PTSD in relatives of critically ill patients in Australia has not been fully evaluated.

OBJECTIVES

To determine if relatives of an Australian critically ill population were interested in using ICU diaries. To determine the prevalence and impact of ICU diaries upon symptoms of PTSD, depression and anxiety in relatives of an Australian critically ill population.

METHODS DESIGN

Prospective, observational, exploratory study.

SETTING

Royal Adelaide Hospital (RAH), Adelaide, Australia.

PARTICIPANTS

One hundred and eight consecutive patients, staying >48h in a level 3 ICU were identified. A survey using DASS-21, IES-R questionnaires was performed on admission followed by a repeat survey 90days post discharge from ICU. An IES-R score >33 was used to define severe PTSD symptoms. A comparison between subjects who did and did not complete their diaries was performed.

RESULTS

Forty subjects refused to participate, eight were excluded, and sixty family members were included for analysis, thirty-six of whom completed diaries. There was no statistically significant difference between PTSD symptom scores at follow-up controlling for useful diary completion (complete - see methods) and PTSD at baseline. There was a statistically significant association between PTSD and unemployment, controlling for PTSD at baseline (P value=0.0045). Family members had significantly higher odds of PTSD at baseline compared to 3 month follow up (P value=0.0092, Odds Ratio=3.3, 95% CI: 1.3, 8.2). This was independent of the completeness of the diaries and adjusted for clustering on subject. Family members with incomplete diaries were less likely to report depressive symptoms at baseline (P value=0.0218, estimate=-4.6, 95% CI: -8.5, -0.7). Diary completion was not indicative of the likelihood of family members to report PTSD symptoms (P value=0.5468, estimate=-1.6, 95% CI: -6.8, 3.6).

CONCLUSION

ICU diaries were often not completed and completion did not appear to be related to the incidence of stress, anxiety, depression and PTSD symptoms in the families of patients in the ICU. This may be because Australian families are generally not interested in maintaining a diary.

Assessment of hypoxia, sedation level, and adverse events occurring during inhalation sedation using preadjusted mix of 30% nitrous oxide + 70%oxygen

PURPOSE

To assess the efficacy of nitrous oxide (N2O)-oxygen (O2) inhalation sedation by rapid induction technique using preadjusted mix of 30% N2O and 70% O2 in children.

MATERIALS AND METHODS

Sixty children with a treatment plan which included pulp therapy were recruited for the study. Children categorized 3 and 4 of Frankl behavior rating scale and American Society of Anesthesiologists health status I and II were included for the study. Children were distributed into study group (Group-I) and control group (Group-II) by fishbowl randomization. Children in Group-I were induced inhalation sedation using a preadjusted mix of 30% N2O and 70% O2 through rapid induction technique, and children in Group-II were exposed to inhalation sedation by conventional slow induction technique. Parameters such as least oxygen saturation, sedation levels by Richmond Agitation-Sedation Scale, time taken to achieve ideal sedation, maximum N2O concentrations used, and adverse events were recorded and evaluated for each procedure. Data were analyzed using independent sample t-test and Chi-square tests.

RESULTS

Analysis of data showed statistically significant difference between both groups in time taken to achieve ideal sedation (P < 0.001). No significant difference was seen in incidence of hypoxia (P < 0.512), maximum N2O concentrations used (P < 0.118), and occurrence of any adverse events.

CONCLUSION

None of the children from both groups exhibited hypoxia. Sense of detachment was seen in one child each from both groups. Rapid induction by preadjusted mix resulted in ideal sedation in 57% children of the Group-I; rest had achieved these levels at 40% N2O. There was a significant difference in the time taken to achieve ideal sedation by rapid induction which was almost half the time taken with slow induction.

Plasma torch toothbrush a new insight in fear free dentisry

Dental treatment is considered painful either because of fear or anxiety. Even though fear and anxiety could be managed; the needle pricks and the heat generated with drills are both painful and destructive to the tissues of the tooth. A new technology which can reduce the pain and destruction of the dental tissues will be of huge value. Plasma torch toothbrush fits into such criteria and when developed fully, will be able to apply for many of the dental procedures for increasing the efficiency.

Solitary nodular lesion of tongue- a rare entity

The solitary, nodular lesions of the oral mucosa present a diagnostic dilemma to the dentist with their analogous presentation. The lesions that appear on the tongue, a soft muscular organ are distinct and even rarer with varied manifestations. Oral mucosa presents lesions of the tongue in all age groups that may range from a small nodular swelling and ulcer formation in an infant of a few days old to an ulcer or a lesion in a 70-year-old. The reason for the appearance of an ulcer may be trauma to the soft tissues in an infant may be due to the presence of natal teeth to the presence of a sharp tooth in the older individuals. These lesions have to be clinically and histologically correlated for the final outcome of the diagnosis, so that there is no chance of any recurrence. We present a unique case of a solitary nodular lesion on the ventral surface of tongue On a 6 year female, where there was a recurrence after surgical excision and after an unusual therapy of non surgical resolution, no recurrence was observed.

Comparison of phenytoin with auranofin and chloroquine in rheumatoid arthritis--a double blind study

OBJECTIVE

To evaluate efficacy of phenytoin in modifying the course of rheumatoid arthritis (RA) by comparing it to gold (auranofin) and chloroquine.

METHODS

A double blind, randomized study of 6 months' duration was conducted at the Nizam Institute of Medical Sciences, Hyderabad, India. One hundred and thirty-two patients with active RA (defined by the 1987 ARA criteria) were entered into the study and randomized into 3 groups: phenytoin, chloroquine, or auranofin.

RESULTS

Full data were evaluable in 100 patients who satisfactorily completed the protocol (phenytoin, 35; auranofin, 30; and chloroquine, 35). Twenty-four patients were noncompliant and did not take medication or return for evaluation; 8 patients had the drug withdrawn because of side effects before study completion. For each of the 3 drugs all clinical and laboratory variables improved when pre and posttreatment values (p < 0.05 to 0.001) were compared. There was a greater reduction in posttreatment mean morning stiffness in the chloroquine group than in the phenytoin and auranofin groups (p < 0.05). Posttreatment grip strength was also greatest in the chloroquine group. On the other hand, there were statistically significant decreases in IgM levels in both the phenytoin and auranofin groups (p < 0.001), but not with chloroquine. Among the 53 patients with a disease history of 3-6 months, global outcome was best with phenytoin (16/17), compared to chloroquine (12/18) and auranofin (12/18) (p < 0.03). However, there was no such difference in the 47 patients in all 3 groups with a disease history longer than 6 months. Eight patients had side effects (phenytoin, auranofin, 2; chloroquine, 1) requiring withdrawal of the drug. However, the incidence of side effects was not significantly different for the 3 drugs.

CONCLUSION

Our data indicate that phenytoin is comparable to auranofin and chloroquine in its efficacy in RA and may be considered an alternative disease modifying agent for RA.
