Simplified noncultured autologous cell grafting for the treatment of chronic nonhealing ulcers: the six-well plate technique.

Chronic recalcitrant ulcers are associated with severe morbidity, and there are few effective treatment options available. Living skin substitutes are an important form of adjuvant therapy to enhance healing of such wounds. We investigated a novel, simplified, noncultured, autologous, cell grafting procedure, using a six-well plate technique, to treat chronic recalcitrant wounds. This was a prospective pilot study that involved harvesting an ultrathin split-skin graft from the gluteal region, which was washed, separated and prepared in six different wells to obtain an autologous mixture of keratinocytes, melanocytes and fibroblasts; this was subsequently applied directly to the wound using a hyaluronic acid (HA) matrix. Eight patients with a total of 14 ulcers were recruited. The primary endpoint assessed was the percentage of re-epithelialization of the ulcers. Secondary endpoints included quality of life and wound bed indices. At baseline, the median wound surface area was 7.4 cm(2) (mean 17.6 ± 23.6 cm(2) , range 0.5-80.0 cm(2) ) with a median duration of 18 months (mean 70.2 ± 95.9, range 3-216 months). The median wound surface area was reduced by 74.3%, from 7.4-1.9 cm(2) , at the final visit. Overall, 28.3% of the ulcers achieved complete healing, and 71.3% of the ulcers had reduction in wound size. Post-graft, there was also improvement in secondary wound bed parameters and all quality of life domains of the Cardiff Wound Impact Schedule. These results suggest that this noncultured autologous six-well technique might be beneficial for treating recalcitrant ulcers.

Hypothyroidism and major depression: a common executive dysfunction?

Little is known about the possible link between the cognitive disorders associated with hypothyroidism and those encountered in depression. This study examines attentional and executive functions as well as the intensity of anxiety and depressive symptoms in hypothyroidism and major depression and the possible link between these symptoms and cognitive disturbances. This study confirms the existence of psychomotor slowing associated with attentional and executive disturbance in major depression as well as in hypothyroidism. However, while depressed subjects manifested a conscious bias with material of negative emotional valence, no such bias was found in the hypothyroid subjects. While the hypothyroid state is accompanied by anxiety/depressive symptoms, it seems that the latter are too discrete for an attentional bias to be observed with material with a negative emotional valence.

Anxiety and depression, attention, and executive functions in hypothyroidism.

BACKGROUND: Divergences in cognitive disturbances in hypothyroidism reported in the literature are a result of a methodological bias. METHODS: By using a precise methodology, we examined attention and executive functions in hypothyroidism, verified the presence of anxiety and depressive symptoms in hypothyroidism, and examined the possible link between these symptoms and the cognitive disturbances (searching for attentional bias for words with a negative emotional valence). We administered a battery of cognitive tests to 23 participants who had undergone thyroidectomy for thyroid carcinoma: for the first time in an euthyroid state, then 3 weeks later (still in the euthyroid state) to assess the test/retest effect, and finally 4 weeks later in an hypothyroid state. We compared their performance with that of a group of 26 control participants who were also administered the same cognitive tests, also 3 times. RESULTS: In hypothyroidism, the thyroid participants were more anxious and depressed than the controls and presented attentional and executive disturbances that reflected general slowing and difficulties in using their capacities of inhibition. However, they did not exhibit an attentional bias for words with a negative emotional valence. CONCLUSIONS: Contrary to what was expected, symptoms of anxiety and not symptoms of depression interfered with the cognitive performance of participants in hypothyroidism.

Socio-economic differences in psychiatric in-patient care.

OBJECTIVE: We seek to investigate socio-economic differences in psychiatric in-patient care regarding admission, treatment and outcome. METHOD: This study is undertaken on a comprehensive and exhaustive psychiatric case register of all psychiatric in-patient care carried out in Belgium in 1997 and 1998 (n=144 754). RESULTS: Lower socio-economic groups were more likely to be compulsorily admitted, to be cared for in a non-teaching or psychiatric hospital, to be admitted in a hospital with unexpectedly long average length of stay and to be admitted to a ward with a more severe case-mix. They were less likely to receive antidepressants and psychotherapies. The improvements in functioning and in symptoms were also less favourable for these groups. The lowest group had a higher risk of dying in the hospital. CONCLUSION: Psychiatric in-patient care is associated with moderate socio-economic differences in access, treatment and outcome. Further research is needed to clarify the causes of such disparities.

Cerebral blood flow and glucose metabolism in hypothyroidism: a positron emission tomography study.

Hypothyroidism is often associated with defective memory, psychomotor slowing, and depression. However, the relationship between thyroid status and cognitive or psychiatric disturbances remains unclear. Using psychometric scales, 10 patients who had undergone total thyroidectomy for thyroid carcinoma were evaluated for depression, anxiety, and psychomotor slowing; they were examined both when euthyroid and hypothyroid after thyroid hormone withdrawal. Positron emission tomography was used, with oxygen-15-labeled water and fluorine-18F-labeled 2-deoxy-2fluoro-D-glucose as the tracers, to correlate the regional cerebral blood flow and cerebral glucose metabolism with the mental state in patients. Two different image analysis techniques (regions of interest and statistical parametric maps) were applied. In hypothyroidism, there was a generalized decrease in regional cerebral blood flow (23.4%, P < 0.001) and in cerebral glucose metabolism (12.1%, P < 0.001) and there were no specific local defects. Patients were also significantly more depressed (P < 0.001), anxious (P < 0.001) and psychomotor slowed (P < 0.005) in hypo than in euthyroid status. These results indicate that the brain activity was globally reduced in severe hypothyroidism of short duration without the regional modifications usually observed in primary depression.

Use of a placebo in clinical trials.

The use of a placebo control group in the evaluation of a new product is today considered by most as a necessary condition of experimental drug research. Placebo response is an essential consideration in all clinical trials. If not properly controlled, incorrect and dangerous conclusion may be inferred for a product efficacy and safety profile. However, the inclusion of a placebo group in clinical trials in neuropsychiatric research raises several ethical and scientific questions. Whereas in certain indications, such as suicidal patients and severe and psychotic depression, the use of a placebo is generally not accepted, it is difficult to assess drug efficacy. This article discusses the concept of placebo in clinical trials, the occurrence of adverse events after placebo treatment and the high response rate of placebo in neuropsychiatric clinical research. The experimental methodology to adequately control all the factors involved is also analysed and discussed.

Lithium compared to valproic acid and carbamazepine in the treatment of mania: a statistical meta-analysis.

The hypothesis that lithium is the most appropriate and efficacious pharmacological treatment in the therapy of manic-depressive illness was examined in a meta-analysis. The efficacy of lithium was compared with that of the antiepileptics, carbamazepine and valproic acid. Data sources include the Medline database and relevant references from articles. Only randomised controlled clinical trials with a double-blind assessment of outcomes were included. Lithium levels were required to be within the therapeutic range of 0.4-1.5 mmol/l. The effect sizes were measured by the odds ratio using the Mantel-Haenszel method. No significant difference was observed between the treatment effect of the 3 drugs compared. While the efficacy of the 3 treatments was identical, there is a general tendency in favour of the antiepileptics in the treatment of manic depression with regard to adverse events and treatment tolerance. The impact and importance of this study seriously question the relevance of today's practice of prescribing lithium in the acute management of manic-depressive illness.

Lithium therapy in the treatment of manic-depressive illness. Present status and future perspectives. A critical review.

This article reviews critically the present status of lithium in the treatment and prophylaxis of manic-depressive illness compared to the two anticonvulsant drugs, carbamazepine and valproic acid. Lithium is used successfully in the prophylaxis and treatment of manic-depression. The mechanism by which it exerts its effects is still not very clear. There is much evidence to indicate that lithium may exert its therapeutic action by interfering with the metabolism of phosphoinositides which play an important role in synaptic transmission. Because of lithium's narrow therapeutic/toxic ratio, blood concentration monitoring is crucial. Published data suggest that, compared to lithium, carbamazepine is similar in its relative specificity in treating mania. It is often faster in achieving its antimanic effects and best established as an alternative for patients not responding or intolerant to lithium. Carbamazepine is a good substitute for lithium when severe renal problems exclude the use of lithium. The therapeutic profile of valproic acid in manic-depression, although less extensively studied, appears to be similar to that of carbamazepine. As carbamazepine, it seems to be best indicated in patients with rapid cycles. Whereas lithium inhibits myo-inositol monophosphatase, carbamazepine shows a stimulating effect and valproic acid has no effect on this biochemical target. The implication of the inositol pathway in the pathogenesis of adverse effects, such as neurotoxicity and dermatological irritation, is discussed. A further understanding of this pathway is important for the future development of new lithium-like compounds in order to maximize the therapeutic benefits without the adverse effects.

Plasmatic vasopressin neurophysin in depression: basic levels and relations with HPA axis.

A decreased secretion of arginine vasopressin (AVP) has been implicated in depression. In order to further investigate this hypothesis, we studied the plasma level of the specific peptidergic carrier of AVP, vasopressin neurophysin (hNpI), in 26 depressed inpatients and 16 matched normal controls. On the other hand, AVP has also been involved in the pathophysiology of the cortisol postdexamethasone nonsuppression frequently observed in depression. Therefore, we investigated concomitantly hNpI and cortisol during a dexamethasone (DXM) suppression test. hNpI and cortisol were assessed by radioimmunoassay at 8 AM and 8 PM during 4 consecutive days. From days 2 to 3, 4 mg (DXM) was given orally. hNpI values were not affected by DXM administration. Compared with controls, patients showed higher pre- and post-DXM cortisol values and lower hNpI values. No difference in hNpI values was observed between DXM escapers or nonescapers. Our results are consistent with an impaired AVP secretion in depression and fail to support a role of AVP in the early cortisol escape.

Possibilities in hypopharyngeal reconstruction--comparative study.

A comparative study between three types of hypopharyngeal reconstruction after laryngopharyngectomy is presented by evaluation of the following parameters: complications, duration of hospitalization and postoperative swallowing time. Each group contains the five most recently cases treated at the E.N.T. department of the K.U. Leuven. In recent years, the following types of hypopharyngeal reconstruction were used: the pectoralis major flap, the free radial forearm flap and the revascularized jejunum interposition. For reconstruction of circumferential hypopharyngeal defects after total laryngopharyngectomy, the jejunal graft presents hopeful results.

[Relevance of using the concept of reactional psychosis]. / Pertinence de l'utilisation du concept de psychose réactionnelle.

Reactive Psychosis can be a matter of controversy with respect to its pragmatic use. This is especially true in the Scandinavian countries, where two streams of opinion clash, one satisfied with the DSMIII's notion of "Brief Reactive Psychosis", supplemented with information on other Axes, and one stressing the advantage of retaining the wider range of the Scandinavian notion, and even of linking it up with the "Cycloid Psychosis". A certain consensus has emerged to recognize that further research is absolutely necessary to close the debate.
