This study reports on self-reported depressive symptoms, assessed with the Children's Depression Inventory (CDI), in a school sample of 685 Italian students. The participants were 254 males and 431 females, the age range of the subjects was 8 to 17 years (mean age 13.0 +/- 2.8 years). The CDI mean score was 10.49 +/- 2.76. According to our data, about 10% of the subjects scored higher than the clinical threshold of 20. More than 1/3 of the students reported thoughts of death, but only 2.2% had explicit suicidal ideation. Girls scored higher than boys, and young adolescents (11-13 years) scored lower than pre-pubertal children and older adolescents, and showed fewer thoughts of death. Factorial analysis yielded seven factors, a general factor with no predominant theme, two factors related to academic self-image and body image, and four related to anhedonia-withdrawal, hypocondria-asthenia, irritability-opposition, and loss of appetite.

The main mechanisms of the chronopathological forms of magnesium depletion associate a low Mg intake with various dysregulating biorhythms. The differentiation between forms with hyperfunction and forms with hypofunction of the biological clock is seminal and the main marker is the production of melatonin (MT). The clinical forms of the various patterns of the chronopathological forms of Mg depletion may be central or peripheral. The clinical forms with hyperfunction of the biological clock (marker: increase in MT) may associate diverse expressions of nervous hypoexcitability: depression (i.e. Seasonal affective disease); cephalalgias nocturnal, without photophobia (i.e. cluster headaches); dyssomnia LASPS (advanced sleep phase syndrome) particularly]; asthenia and myalgias (i.e. fibromyalgia, chronic fatigue syndrome). The main comorbidity is found with depressive states. The therapy relies on classical bright light phototherapy, sometimes associated with psychoanaleptics. The clinical forms with hypofunction of biological clock (marker: decrease in MT) may associate various signs of nervous hyperexcitability (HEN): anxiety (from generalized anxiety to panic attacks); cephalalgias diurnal with photophobia (mainly migraine); dyssomnia [DSPS (delayed sleep phase syndrome) particularly, jet lag, night work disorders, age related insomnia, sometimes with inappropriate behaviour; photogenic epilepsia, generalized or focal; some clinical forms of chronic fatigue syndrome and fibromyalgia. The main comorbidity is between migraine and epilepsia. The treatment relies on the diverse forms of darkness therapy, possibly with the help of some psycholeptics: anxiolytics and anticonvulsants. The indications of chromatotherapy remain to be validated.

Enerion was used in the treatment of 40 patients with psychovegetative syndrome and asthenia. Before treatment, the patients have pronounced asthenia appearances, anxiety disorders, relevant autonomic disorders, mild depression and decrease of working capacity, attention concentration and memory. The treatment was conducted as monotherapy during 28 days with enerion dosage 400 mg/day. After treatment, expression of autonomic and asthenic disorders was reduced significantly, along with improvement of psychometric and neurophysiological indices. High efficacy of the medication was detected in 75% of the patients and moderate one--in 25%. The drug was well-tolerated.

A number of newer antianginal agents, including nicorandil, trimetazidine, and ivabradine, have been synthesized in recent years, but ranolazine, a piperazine derivative that partially inhibits fatty acid oxidation and the late INa current in animal models, is of particular interest mechanistically. Earlier clinical trials with immediate-release ranolazine led to the current sustained-release version tested in the Monotherapy Assessment of Ranolazine In Stable Angina (MARISA) (n = 193) and Combination Assessment of Ranolazine In Stable Angina (CARISA) trials (n = 823) of patients with chronic angina and severe limitation of exercise capacity (ie, < 5 metabolic equivalents). MARISA was a placebo-controlled, randomized trial that compared ranolazine monotherapy (500 mg, 1000 mg, and 1500 mg, twice daily) to placebo. CARISA was a placebo-controlled trial that randomized patients on background beta-blocker or calcium antagonist therapy to placebo or ranolazine (750 mg or 1000 mg, twice daily). Both studies showed a significant increase in total exercise duration, time to angina onset, and time to 1 mm ST segment depression. The average magnitude of increase in exercise duration over placebo was 29 to 56 seconds at peak and 24 to 46 seconds at trough with the 3 doses tested in MARISA, and 24 to 34 seconds greater than placebo with the 2 doses used in CARISA. The beneficial effect was achieved without clinically important changes in rest or exercise heart rate or blood pressure. Weekly angina attack frequency and nitroglycerin usage were significantly reduced in a dose-dependent manner in the 12-week CARISA trial. Reported adverse effects were similar in MARISA and CARISA and consisted of asthenia, nausea, constipation, and dizziness. Syncope, reported in 8 patients at doses of 1000 mg twice daily or more may be related to attenuation of alpha-1 receptor activity. The mean QTc interval increased with dose and was less than 10 msec on ranolazine at 1000 mg twice daily. The mortality rates at 1 and 2 years in MARISA and CARISA open-label run-on studies were 2% and less than 5%, acceptable for this high-risk population with limited exercise capacity. In conclusion, clinical trial evidence with ranolazine to date is consistent with its proposed mechanism of action and demonstrates an effective antianginal profile that may benefit patients with severe chronic angina.

Depressive state in cancer patients is known to meet the criteria of mild depressive episode (F33.0) according to ICD-10. In the earlier stages of the disease and after successful treatment, depressive symptoms are usually combined with anxiety and obsessive fear, moderate appearances of ideator and motor inhibition, with permanent presence of asthenic symptoms. Once the disease is getting severer and the treatment is less successful, asthenia acquires hyposthenic features, with symptoms of apathy and dysphoria being attached. Cypramil was shown to be an effective medication in the treatment of depression in patients with malignant tumors of gastric-intestinal tract. The most efficient was the treatment conducted on the earlier stages of the cancer process and in cases of successful surgery and chemotherapy, in combination of depression with anxiety, anxious hypochondria, asthenia. Antidepressants must be used together with psychotherapy.

Quetiapine (QTP) combined with lithium (Li) or divalproex (DVP) for the treatment of mania was evaluated in 2 double-blind, placebo-controlled studies. Patients were randomized to 3 or 6 weeks of treatment with QTP plus Li/DVP or placebo (PBO) plus Li/DVP. Quetiapine was dosed up to 800 mg/d; Li was dosed to achieve serum concentrations of 0.7-1.0 mEq/L and DVP to 50-100 microg/mL. A total of 402 patients were randomized: 197 to QTP + Li/DVP and 205 to PBO + Li/DVP. The mean quetiapine dose in responders was 492 (+/-204) mg/d. Improvement in the Young Mania Rating Scale (YMRS) at day 21 in the QTP + Li/DVP group (-15.29) was statistically superior to the PBO + Li/DVP group (-12.19) (P < 0.05). A statistically significant difference in favor of quetiapine was observed within the first week (P < 0.05). Significantly more QTP + Li/DVP patients achieved a response (> or =50% decrease in the YMRS) at day 21 (QTP + Li/DVP, 55.7%; PBO + Li/DVP, 41.6%;P < 0.01). Improvements in Clinical Global Impression-Bipolar Severity of Illness scores by day 21 were also significantly greater in QTP + Li/DVP-treated patients (-1.59) versus PBO + Li/DVP (-1.19) (P < 0.01). Common adverse events (> or =5% and twice that in the PBO + Li/DVP group) in the QTP + Li/DVP group were somnolence, dry mouth, and asthenia. Quetiapine combined with Li/DVP was not associated with extrapyramidal symptoms (including akathisia) or emergent depression. More QTP + Li/DVP-treated patients completed the trial, and there was no difference in discontinuation rates due to adverse events between the two groups. Quetiapine, in combination with lithium or divalproex, is well tolerated and has superior efficacy to lithium or divalproex alone in the treatment of bipolar mania.

Cytotoxic chemotherapy treatment options for patients with non-small-cell lung cancer (NSCLC) have limited efficacy and are often associated with significant toxicity. Therefore, there is an unmet need for novel drugs that are not only effective in treating this disease but are also well tolerated. Gefitinib is an orally active epidermal growth factor receptor tyrosine kinase inhibitor that blocks the signal transduction pathways implicated in cancer cell growth and survival. It has recently been approved for the treatment of advanced/refractory NSCLC. This review presents the tolerability data from phase I and II gefitinib monotherapy trials, along with data from the worldwide 'Expanded Access Programme' and post-marketing use of gefitinib. Gefitinib was found to be generally well tolerated at the approved dosage of 250 mg/day; the most commonly reported adverse drug reactions (ADRs) were mild to moderate skin rash and diarrhoea, which were manageable and non-cumulative. Other ADRs observed with the use of gefitinib included: dry skin, pruritus, acne, nausea, vomiting, anorexia, asthenia and asymptomatic elevations in liver transaminase levels. Well recognised adverse effects seen with cytotoxic chemotherapy (such as bone marrow depression, neurotoxicity and nephrotoxicity) were not observed. Although the frequency and severity of ADRs increased with the dosage across the range studied (50-1000 mg/day), few patients required dosage reductions or the withdrawal of treatment, and those who did usually received gefitinib >or=600 mg/day.Thus, the available data indicate that gefitinib is well tolerated in patients with a range of solid tumours, including locally advanced or metastatic NSCLC.

Asthma is a chronic, inflammatory disorder of the airways leading to airflow limitation. Its worldwide rise, mainly in developed countries, is a matter of concern. Nocturnal asthma (NA) frequently occurs and concerns two thirds of asthmatics. But, it remains controversial whether NA is a distinct entity or is a manifestation of more severe asthma. Generally, it is considered as an exacerbation of the underlying pathology. The pathological mechanisms most likely involve endogenous circadian rhythms with pathological consequences on both respiratory inflammation and hyperresponsiveness. A decrease in blood and tissue magnesium levels is frequently reported in asthma and often testifies to a true magnesium depletion. The link with magnesium status and chronobiology are well established. The quality of magnesium status directly influences the Biological Clock (BC) function, represented by the suprachiasmatic nuclei and the pineal gland. Conversely, BC dysrythmias influence the magnesium status. Two types of magnesium deficits must be clearly distinguished: deficiency corresponding to an insufficient intake which can be corrected through mere nutritional Mg supplementation and depletion due to a dysregulation of the magnesium status which cannot be corrected through nutritional supplementation only, but requires the more or less specific correction of the dysregulation mechanisms. Both in clinical and in animal experiments, the dysregulation mechanisms of magnesium depletion associate a reduced magnesium intake with various types of stress including biological clock dysrhythmias. The differenciation between Mg depletion forms with hyperfunction of BC (HBC) and forms with hypofunction of BC (hBC) is seminal and the main biological marker is melatonin (MT) production alteration. We hypothesize that magnesium depletion with HBC or hBC may be involved in chronopathological forms of asthma. Nocturnal asthma would be linked to HBC, represented by an increase in MT levels. The corresponding clinical forms associate diverse expressions of nervous hypoexcitability such as depression, cluster headaches, dyssomnia, mainly advanced sleep phase syndrome, some clinical forms of chronic fatigue syndrome and of fibromyalgia. The main comorbidities are depression and/or asthenia. They take place during the night or the "bad" seasons (autumn and winter) when sunshine is at a minimum. The corresponding chronopathological therapy relies on bright light phototherapy sometimes with additional psychoanaleptics. Conversely, asthma forms linked to hBC are less frequently studied as a whole and present a decrease in MT levels. They associate various signs of nervous hyperexcitability such as anxiety, diurnal cephalalgia (mainly migraine), dyssomnia, mainly delayed sleep phase syndrome, and some clinical forms of chronic fatigue syndrome and of fibromyalgia. The treatment relies on diverse forms of "darkness therapy", possibly with the help of some psycholeptics. Finally, the treatment of asthma involves the maintenance of a standard dosing schedule of anti-asthma drugs, a balanced magnesium intake and the appropriate treatment of the chronopathological disorders.

Forty patients (37 women, 3 men, age 47.3 +/- 3.4 years) with diagnosis of involutional hysteria (IH) have been studied. Two variants of IH have been identified. The first one, hystero-hypochondriac, is characterized by a prevalence of conversions, asthenia and hypochondria; the second--by hysterical depression, overvalued erotomania with premorbid histrionic personality disorder. The hypochondriac variant of IH is triggered by somatogenic disorders (gynecological surgeries, cardiovascular diseases) as well as various psychogenic factors (conflicts in professional and family life). Manifestation of the second variant is realized by the mechanism of key feeling, with trigger factors related to the objects of overvalued events (adultery, break-up of love affairs).

Alpha-mannosidosis is characterized by mild to moderate intellectual disability (ID), moderate to severe neurosensory hearing loss, frequent infections, psychomotor disturbances and skeletal dysmorphism. For the first time, a panel of nine alpha-mannosidosis patients with psychiatric symptoms is presented. The clinical picture has several similarities: a physical or psychological stressor precedes a rapid development of a state of confusion, delusions, hallucinations, anxiety and often depression leading to a severe loss of function. This usually lasts 3-12 weeks, and is followed by a period of somnolence and asthenia. It may be more prevalent in females. In four of the described patients search for organic causes of the syndrome was performed, but revealed only negative findings. Because of the limited number of cases no firm conclusion about the benefit of various psychotropic drugs can be drawn from our observation. Psychiatric symptoms could affect as many as 25% of patients with alpha-mannosidosis. First onset is typically in late puberty to early adolescence. The episodes may be recurrent, and of limited duration although medication may be necessary to alleviate symptoms. Our observations indicate that alpha-mannosidosis is associated with an increased risk of psychiatric symptoms. These should not be dismissed as part of the ID but should give rise to the initiation of adequate diagnostic work-up, treatment and support.
