Aripiprazole augmentation in treatment-resistant depression.

BACKGROUND: Evidence is accumulating to support the use of atypical neuroleptics as adjunctive treatment for refractory mood disorders, although there are currently no published data on the efficacy of an atypical neuroleptic in treatment-resistant depression when a previous trial of drug from the same class has failed. The authors hypothesized that aripiprazole would be efficacious in augmenting antidepressant treatment in resistant patients with non-psychotic unipolar depression who had previously failed a trial of another atypical neuroleptic. METHODS: This study was a retrospective chart review of the efficacy of aripiprazole augmentation in 30 treatment-resistant unipolar depression patients who had failed multiple previous antidepressant trials and had also failed augmentation with at least one other atypical neuroleptic. Prospective Global Assessment of Functioning and Clinical Global Impressions-Improvement scores were completed on each patient throughout treatment. RESULTS: Utilizing an intent-to-treat analysis (including 9 patients who dropped out prior to completion of 6 weeks), 46.7% (14/30) patients were rated much improved or very much improved with treatment. This improvement negatively correlated with Thase-Rush staging of treatment resistance. GAF scores also showed a significant improvement. Six of the 14 patients who initially improved subsequently relapsed (yielding a long-term net response rate of 26.7%). CONCLUSION: Aripiprazole may be effective as an antidepressant augmentation agent in highly treatment resistant patients who had failed a prior trial of another atypical neuroleptic.     

Photodynamic therapy

Photodynamic therapy (PDT) is a new modality of cancer treatment. It is based on the use of photosensitizing agents and laser light which interact and produce singlet oxygen. This toxic compound destroys malignant tumours while healthy tissue remains intact. The present paper reviews the method of PDT and its possible clinical applications.     

Weight of the thyroid gland in the Brandenburg district before introduction of iodized salt

The first prospective investigation of thyroid weights of over 20 years old adults in the GDR is presented. The material is based on autopsy findings from the Brandenburg area before using salt with iodine. Judging by the results this area appears as an endemiological one. Relationships to iodine content of drinking water, comparisons with autopsy statistics of other countries, and the role of regional epidemiological differences are pointed out. The importance of the investigation for patients care and the possibility of controlling the effect of using salt with iodine is underlined. The examination of relations between thyroid weight and anthropometric data showed no additional results.     

Eosinophilia-myalgia syndrome with fasciitis and interstitial myositis after L-tryptophan administration]

We describe a 53-year-old women with eosinophilia-myalgia syndrome who suddenly developed severe persistent myalgias of her arms, legs, back, and shoulder after a 5-month period of daily L-tryptophan ingestion, associated with fever, progressive stenocardia and left-sided congestive heart failure. Laboratory tests showed a leukocytosis of 11.2/nl with 3.14/nl eosinophils and an elevated erythrocyte sedimentation rate. There was a marked, predominantly proximal sclerosis of her arms, legs and trunk with a brownish discoloration. The skin of her arms and legs appeared dimpled (peau d'orange). Findings of the electrophysiological examinations were consistent with sensory neuropathy and myositis. Remarkable fasciitis and interstitial myositis were present in a biopsy specimen (from skin to muscle) taken from her thigh. However, eosinophilic infiltrates were rare. Angiography revealed an apical obstructive cardiomyopathy. In this paper, we describe the clinical findings, the course over 2 years, as well as the therapeutic management. Furthermore, the most important differential diagnoses are discussed and the literature is reviewed with special attention given to more recent pathogenic insights into this newly recognized multisystem disease.     

Clinical evaluation of preventive and class-I composite resin restorations.

This study was initiated in 1986 in response to increased interest in restorative procedures favoring preservation of tooth substance and in the search for alternatives to dental amalgams. Eighty-seven preventive resin restorations in permanent molars and 35 occlusal composite resin restorations in primary molars (limited size) and 13 in premolars were followed up for 2 years. They were placed by a large number of operators, mainly dental students under supervision, and rated by five calibrated instructors in accordance with an internationally accepted system for the evaluation of the clinical performance of dental materials. One composite resin (Occlusin) was used. A survival model was used to calculate the cumulative theoretical number of successful treatments of children who had dropped out. For none of the 6 clinical variables was the success rate lower than 91%, and only 3 of 26 failures were of a nature requiring remake or correction. The failures occurred, with a few exceptions, during the 1st year of observation. The two types of restoration have thus proved to be efficient treatments fulfilling all reasonable requirements in modern operative dentistry.     

Development of a short version of the Apathy Evaluation Scale specifically adapted for demented nursing home residents.

OBJECTIVE: Apathy is among the most frequent neuropsychiatric symptoms in dementia, particularly Alzheimer disease. The Apathy Evaluation Scale (AES) has been widely employed for assessing apathy in different patient groups. To further facilitate the usage of the AES, an abbreviated version was constructed. METHOD: On basis of a sample of 356 nursing home residents, a cross-validation procedure was carried out to develop a brief version of the AES. According to a thorough clinical examination, 85% of the residents were demented, 8% presented with mild cognitive impairment, whereas 7% did not present any cognitive deficits. After subdividing the patient group into two matched samples, the first subsample was used to identify problematic items due to defined psychometric and content-related criteria. The original 18-item scale was thus reduced to 10 items. Psychometric properties of the shortened version were subsequently reassessed in the second subsample. RESULTS: The short version demonstrated favorable psychometric properties that could be confirmed by cross-validation with the second sample. Correlations with the original full-length version were high (r = 0.97 for both subsamples); the shortened scale yielded no substantial losses regarding internal consistency or construct validity (correlations with the respective subscales of the Neuropsychiatric Inventory). CONCLUSION: The frequency of apathetic symptoms in the nursing home residents included confirms the clinical importance of apathy for understanding dementia. Given this specific patient population, setting, and mode of data collection, the short-version AES seems to be a valuable and time-efficient instrument for assessing apathy.     

Einfluss von Methadon auf die Entwicklung von Lucilia sericata

The greenbottle fly Lucilia sericata is an insect of great forensic interest for estimating the postmortem interval. The present study investigated the influence of methadone on the development of Lucilia sericata larvae. The results of the study showed a significant acceleration of larval development between day 3 and 5 when methadone is present in the food source. The total development times where shortened by up to 15 h in the group with therapeutic and toxic methadone concentrations. These results should be considered when undertaking forensic entomological examinations.     

Gewaltforschung zum Thema „häusliche Gewalt“ aus kriminologischer Sicht

Domestic violence continues to be a subject of public interest and media presence, especially when it involves spectacular cases ranging from abuse of children to fatal violence in the family. Although domestic violence has been the subject of scientific research for the last three decades, there is still no clear evidence of prevalence and etiology of this particular kind of violence. Since the introduction of the German Violence Protection Act which came into force in January 2002, domestic violence has been met with severe societal and legal sanctions. The consequences for culprits are not only theoretical but also include an increase in criminal proceedings and improved civil court protection. Therefore medical staff, particularly legal medicine, is more than ever confronted with the need to standardize documentation of injuries resulting from domestic violence. In addition, legal medical specialists are often confronted with the victims’ personal and social problems. This paper gives an insight into the historical background and recent law reforms which have created legal sanctions and protection against domestic violence.     

Lumbosacral glioblastoma and leptomeningeal gliomatosis complicating the course of a cervicothoracic astrocytoma WHO grade II

CASE REPORT: The reported female patient underwent sub-total resection of an intra-medullary cervicothoracic astrocytoma classified as WHO grade II in 1984 at the age of 18 months and received local irradiation. In 1989, a local recurrence was diagnosed and a partial resection was performed. Sixteen years later, a small recurrent cervicothoracic tumour was found and spinal seeding to the equine nerve roots and the left cerebellar cortex was apparent on MRI. The patient was implanted with a ventriculoperitoneal shunt for a pseudo-tumour cerebri producing papilloedema, which eventually lead to amaurosis. After an extended biopsy, the invasive lumbosacral tumour was classified as glioblastoma multiforme. Two months later, the patient died after rapid progression of the caudal cranial nerve dysfunction. DISCUSSION AND CONCLUSION: Anaplastic progression and dissemination of spinal astrocytomas even two decades after initial diagnosis and treatment are rare. Therapies and diagnostic follow-up strategies are discussed.     

Preclinical evaluation of coronary vascular function after cardioplegia with HTK and different antioxidant additives.

OBJECTIVE: Due to limited resources, improvement of preservation solutions is still of great importance in cardiac transplant surgery. New additives with antioxidant properties were tested with respect to coronary function of isolated rat hearts. METHODS: Bretschneider HTK solution containing none or an antioxidant additive (deferoxamine, trolox or LK 616) was used for 8h cold cardioplegia. After reperfusion with Krebs-Henseleit buffer (KHB), we assessed vascular dilator capacity (bradykinin, adenosine triphosphate, reactive hyperemia), myocardial function (left ventricular developed pressure, heart rate, oxygen consumption) and release of biochemical markers (aspartate aminotransferase, creatine kinase, lactate dehydrogenase, troponin, adenosine). RESULTS: Bradykinin- and adenosine triphosphate-induced vasodilations were largely reduced in hearts stored 8h in traditional HTK as compared to unstored controls. Storage in HTK+LK 616 significantly improved bradykinin-induced vasodilation. Vasodilation toward ATP was best preserved in hearts stored in HTK+deferoxamine. Deferoxamine and trolox, both improved reactive hyperaemic response during reperfusion. Left ventricular pressure development was significantly reduced after 8h cardioplegia, but no difference existed between different cardioplegia groups. Release of biochemical markers of tissue injury was similar in all cardioplegia groups. After storage in HTK+LK 616 (100 microM), however, heart marker release was slightly augmented as compared to HTK. CONCLUSIONS: Despite similar myocardial function and marker release, coronary vascular function after cardioplegic storage may profit by addition of iron chelators (or antioxidants) to traditional HTK solution.
