RESUMO

UNLABELLED: CASE HISTORY PHYSICAL EXAMINATION: A 79-years-old female suffered from cervical pain for several years which radiated in both shoulders. A nodular goiter was already known and therefore a radio iodine treatment had been planned. Eight months ago the patient noticed a progressing breathlessness. Emergency admission happened due to inspiratory stridor and severe attacks of dyspnoea. Sufficient breathing was only possible by wearing a rigid cervical collar. There were no neurological deficits. EXAMINATION: Tracheoscopy showed a mass in the dorsal cervical region. The cervical x-ray, computed tomography and magnet resonance imaging conformed a distinct spondylopathy at the leading edge of the cervical vertebral bodies including ventralisation of the oesophagus and narrowing of the trachea (>50%). THERAPY AND COURSE: Simultaneously a total thyroidectomy, including neuromonitoring of the N. vagus, and ventral microsurgical resection of the spondylopathy was performed. There was no relapse of dyspnoea in the following year. CONCLUSION: The coincidence of a goiter and ventral cervical spondylopathy accompanied by significant dyspnoea is remarkable. The order of diagnostic steps in this emergency case displays a major problem. The patient was scheduled for goiter surgery and admitted as emergency due to a stridor. The cervical spondylopathy was diagnosed by tracheoscopy and cervical x-ray. This case report emphasizes the importance to think about cervical lesions in the presence of a goiter and dyspnoea. To find out quickly whether there is a cervical lesion or not a x-ray should be obtained. Missing these lesions can result in a fatal course.

RESUMO

Randomized phase III trials have shown significant improvement of survival 1, 2, and 3 years after implantation of 1,3-bis (2-chloroethyl)-1-nitrosourea (BCNU) wafers for patients with newly diagnosed malignant glioma. But these studies and subsequent non-phase III studies have also shown risks associated with local chemotherapy within the central nervous system. The introduction of concomitant radiochemotherapy with temozolomide (TMZ) has later demonstrated a survival benefit in a phase III trial and has become the current treatment standard for newly diagnosed malignant glioma patients. Lately, this has resulted in clinical protocols combining local chemotherapy with BCNU wafers and concomitant radiochemotherapy with TMZ although this may carry the risk of increased toxicity. We have compiled the treatment experience of seven neurosurgical centers using implantation of carmustine wafers at primary surgery followed by 6 weeks of radiation therapy (59-60 Gy) and 75 mg/m(2)/day TMZ in patients with newly diagnosed glioblastoma followed by TMZ monochemotherapy. We have retrospectively analyzed the postoperative clinical course, occurrence and severity of adverse events, progression-free interval, and overall survival in 44 patients with newly diagnosed glioblastoma multiforme. All patients received multimodal treatment including tumor resection, BCNU wafer implantation, and concomitant radiochemotherapy. Of 44 patients (mean age 59 ± 10.8 years) with glioblastoma who received Gliadel wafer at primary surgery, 28 patients (64%) had died, 16 patients (36%) were alive, and 15 patients showed no evidence of clinical or radiographic progression after a median follow-up of 15.6 months. At time of analysis of adverse events in this patient population, the median overall survival was 12.7 months and median progression-free survival was 7.0 months. Surgical, neurological, and medical adverse events were analyzed. Twenty-three patients (52%) experienced adverse events of any kind including complications that did not require treatment. Nineteen patients (43%) experienced grade 3 or grade 4 adverse events. Surgical complications included cerebral edema, healing abnormalities, cerebral spinal fluid leakage, meningitis, intracranial abscess, and hydrocephalus. Neurological adverse events included newly diagnosed seizures, alteration of mental status, and new neurological deficits. Medical complications were thromboembolic events (thrombosis, pulmonary embolism) and hematotoxicity. Combination of both treatment strategies, local chemotherapy with BCNU wafer and concomitant radiochemotherapy, appears attractive in aggressive multimodal treatment schedules and may utilize the sensitizing effect of TMZ and carmustine on MGMT and AGT on their respective drug resistance genes. Our data demonstrate that combination of local chemotherapy and concomitant radiochemotherapy carries a significant risk of toxicity that currently appears underestimated. Adverse events observed in this study appear similar to complication rates published in the phase III trials for BCNU wafer implantation followed by radiation therapy alone, but further add the toxicity of concomitant radiochemotherapy with systemic TMZ. Save use of a combined approach will require specific prevention strategies for multimodal treatments.

RESUMO

Mild depressive syndromes are highly prevalent among primary-care patients. Evidence-based treatment recommendations need to be derived directly from this diagnostically heterogeneous group. The primary aim was to assess the efficacy of sertraline and cognitive-behavioural group therapy for treatment of depressed primary-care patients, the secondary aim was to evaluate if receiving treatment according to free choice is associated with a better outcome than randomization to a particular treatment. We conducted a randomized, placebo-controlled, single-centre, 10-wk trial with five arms: sertraline (flexible dosages up to 200 mg/d) (n = 83); placebo (n = 83); manual-guided cognitive-behavioural group therapy (one individual session and nine group sessions per 90 min) (n = 61); guided self-help group (control condition, n = 59); and treatment with sertraline or cognitive-behavioural group therapy according to patients' choice (n = 82). From 1099 consecutively screened adult patients, 368 formed the intent-to-treat population with milder forms of depression. Primary outcome was a global efficacy measure combining z-converted Hamilton Depression Rating Scale and clinician-rated Inventory for Depressive Symptomatology scores. Sertraline was superior to placebo (p = 0.03). Outcome for guided self-help groups was worse compared to cognitive-behavioural group therapy (p = 0.002) and compared to all other treatment arms including pill placebo (secondary analyses). Outcome in the patients' choice arm was similar to that in the sertraline and cognitive-behavioural group therapy. Overall, sertraline is efficacious in primary-care patients with milder forms of depression. The superiority of cognitive-behavioural group therapy over guided self-help groups might partly be explained by 'nocebo' effects of the latter.

RESUMO

OBJECTIVE: Depressive episodes can begin abruptly or start very slowly (over weeks). This relevant clinical feature of affective disorders has not been systematically investigated so far. The aim of this study was to analyze speed of onset of depressive episodes in patients with unipolar depression (UD) and bipolar affective disorders (BD). METHODS: 158 adult patients with UD (N = 108) and BD (N = 50) were examined using the structured "Onset-of-Depression Inventory". Only patients without acute critical life events preceding the onset were included in the study. RESULTS: There was a significant positive correlation between speed of onset of the present and that of the preceding depressive episode (rho = 0.66; p < 0.001). The association between speed of onset and speed of decay of depressive episodes failed to be significant (rho = 0.20; p = 0.09). Patients with bipolar disorder were found to develop depressive episodes significantly faster than patients with major depression (p < 0.001): Whereas depressive episodes started in 58% of patients with bipolar disorder within one week, this was only the case in 7.4% of patients with major depression. CONCLUSIONS: Within subjects, the speed of onset of depression is similar across different episodes. In the absence of acute critical life events, rapid onset of depressive episodes (within one week) is typical for bipolar depression, but not for unipolar depression. A rapid onset of depressive episodes might point to BD in patients with solely depressive episodes in the past and to subgroups with different neurobiological pathogenetic mechanisms.

RESUMO

OBJECTIVE: Depressive episodes can have a very fast onset (< 1 hour) or start very slowly (> 1 month). This interesting aspect, pointing to different neurophysiological pathomechanisms, has not been systematically evaluated so far. The aim of this study was to describe speed of onset of depressive episodes in a consecutive sample of patients with at least 1 depressive episode and to investigate potential differences between patients with major depression versus bipolar affective disorders concerning this variable. METHOD: We examined 158 consecutive adult patients with major depression (N = 108) and bipolar disorder (N = 50) diagnosed according to criteria of the International Statistical Classification of Diseases, 10th revision, by applying the structured Onset-of-Depression Inventory. Patients with acute critical life events preceding the onset were excluded from final analyses. Data were collected between December 2001 and January 2007. RESULTS: There was a significant positive association between speed of onset of the present depressive episode and that of the preceding depressive episode (rho = 0.66, p < .001). Patients with bipolar disorder developed full-blown depressive episodes significantly faster than patients with major depression (p < .001): Whereas depressive episodes began within 1 week in 58% of patients with bipolar disorder, this was the case in only 7.4% of patients with major depression. CONCLUSION: Intraindividually, the speed of onset of depression is similar across different episodes. In the absence of acute critical life events, fast onset of depressive episodes (within 1 week) is common in bipolar disorder but rare in major depression. This aspect might be useful to identify depressive episodes occurring within a bipolar affective illness and might characterize a subgroup of patients with a distinct neurobiology.

RESUMO

The purpose of our study was to describe an efficient, reliable and inexpensive surgical method for cerebral venous blood gas sampling in acutely instrumented pigs in a research setting. Parameters from the blood samples are used to monitor brain perfusion and oxygenation in different animal models. To the authors' knowledge, this is the first detailed description of an accurate surgical technique for catheterization of the sagittal sinus in pigs.

RESUMO

The authors present three cases of iatrogenic paracervical abscesses caused by infiltration therapy of pain medications used in conservative treatment in patients with chronic cervicobrachialgia. All three patients had received this therapy several times before presenting with clinical signs of a local infection. The diagnosis was made based on results of the clinical examination, laboratory tests, and magnetic resonance imaging. The organism isolated was Staphylococcus aureus in all cases. After immediate surgery and long-term antibiotic therapy, all patients had a good outcome. The authors conclude that infectious complications after invasive outpatient treatment often go undiagnosed, but as shown in these three cases can lead to acute and sometimes life-threatening complications. If the disease is diagnosed early, immediate surgical evacuation combined with antibiotic therapy results in recovery. For medicolegal reasons it should kept in mind that even a routine injection may lead to such complications.

RESUMO

OBJECT: Pyogenic vertebral osteomyelitis is of special interest to neurosurgeons because it often results in acute neurological deterioration and requires a combination of adequate surgical and conservative treatment. The aim of the current study was to evaluate the strategy of a primary surgical approach to this disease. METHODS: A group of 24 patients with the clinical and radiological signs of acute pyogenic spondylodiscitis was prospectively followed from 1998 to 2004. Of these, 20 had underlying diseases such as diabetes mellitus, chronic alcoholism, and liver cirrhosis. The main causative organism was Staphylococcus aureus. Most infections were localized in the thoracic or lumbar spine (10 cases each); 15 infections were associated with epidural abscesses. Because of a delay in diagnosis, 13 patients presented with neurological deficits on admission. Patients with a complete or rapidly progressing neurological deficit underwent immediate surgery. In patients with minor or no deficits or in a stable neurological condition, surgery was delayed for 3 to 5 days. This group was treated with immobilization and intravenous antibiotic drugs before surgery. Surgical procedures included ventral, dorsal, and combined approaches in one- or two-stage operations. Antibiotic treatment included the use of broad-spectrum antibiotic drugs delivered intravenously for at least 10 days, followed by orally administered antibiotics for 3 months. Twenty patients were independent on follow-up review, 15 with no or minor handicaps. Severe septicemia and multiorgan failure developed in two patients, and these two died of their disease. Major complications were mainly due to long-term antibiotic therapy. CONCLUSIONS: Surgical treatment is the modality of choice in patients with acute spinal osteomyelitis. It is especially indicated in patients with progressive or severe neurological deficits and spinal deformity. In experienced hands, surgery is safe and offers the advantages of spinal cord decompression, immediate mobilization, and correction of spinal deformity. The decision whether an anterior or posterior approach should be used must be made on an individual basis.
