Cognitive-behavioral treatment for severe anger in posttraumatic stress disorder.

With a randomized group design, a 12-session anger treatment was evaluated with severely angry Vietnam War veterans suffering combat-related posttraumatic stress disorder (PTSD). Eight participants in anger treatment and 7 in a routine clinical care control condition completed multiple measures of anger control, anger reaction, and anger disposition, as well as measures of anxiety, depression, and PTSD at pre- and posttreatment. Controlling for pretreatment scores, significant effects were found on anger reaction and anger control measures but not on anger disposition or physiological measures. Eighteen-month follow-up (for both completers and dropouts) supported the posttreatment anger control findings. The challenges of treatment research with this refractory population are discussed.

A randomized controlled trial of cognitive-behavioral treatment for posttraumatic stress disorder in severe mental illness.

A cognitive-behavioral therapy (CBT) program for posttraumatic stress disorder (PTSD) was developed to address its high prevalence in persons with severe mental illness receiving treatment at community mental health centers. CBT was compared with treatment as usual (TAU) in a randomized controlled trial with 108 clients with PTSD and either major mood disorder (85%) or schizophrenia or schizoaffective disorder (15%), of whom 25% also had borderline personality disorder. Eighty-one percent of clients assigned to CBT participated in the program. Intent-to-treat analyses showed that CBT clients improved significantly more than did clients in TAU at blinded posttreatment and 3- and 6-month follow-up assessments in PTSD symptoms, other symptoms, perceived health, negative trauma-related beliefs, knowledge about PTSD, and case manager working alliance. The effects of CBT on PTSD were strongest in clients with severe PTSD. Homework completion in CBT predicted greater reductions in symptoms. Changes in trauma-related beliefs in CBT mediated improvements in PTSD. The findings suggest that clients with severe mental illness and PTSD can benefit from CBT, despite severe symptoms, suicidal thinking, psychosis, and vulnerability to hospitalizations.

Trauma and posttraumatic stress disorder in severe mental illness

The objective of this study was to evaluate the performance of a new, compact, dynamic diffusion cell for in vitro transdermal permeation. These so-called Kelder-cells were developed as an automated alternative to the static Franz diffusion cells. The new cells were used in combination with the ASPEC-system (automatic sample preparation with extraction columns) which was initially designed for the automation of solid-phase extractions. Three variables were tested to optimize the performance of the new cell system: injection height into the inlet compartment, volume flowing through the receptor compartment and temperature. Experiments were performed using the tritium labelled anticholinergic [3H]dexetimide permeating through an artificial membrane (Silastic). The injection height of the needle into the inlet compartment of the cell should be programmed at -34 mm to ensure complete air tightness, thus forcing the buffer to flow through the cell. The volume of buffer flow through the receptor compartment is important in maintaining sink conditions: a volume of 117 microliters was chosen to replace the total content of the cell (84 microliters) every 2 min. The temperature was precisely controlled in a thermostatic cabinet to minimize variations in experimental conditions. For [3H]dexetimide, an increase in temperature of 20 degrees C reduced the lag time by a factor of approximately two, however the influence on the flux was negligible. The data for the Kelder-cells were comparable with static Franz diffusion cells at a pseudo-steady state, however Kelder-cells have the advantage of automatic sampling, continuous replacement of the receptor solution, and unattended operation over at least 24 h.     

Imaginal flooding in the treatment of a posttraumatic stress disorder.

A 36-yr-old Vietnam veteran was treated for the anxiety-related symptoms of a posttraumatic stress disorder during a 22-day inpatient hospitalization. Primary treatment was the exposure technique of imaginal flooding using the intrusive thoughts (nightmares and flashbacks) associated with the traumatic events. Self-monitored data, the State-Trait Anxiety Inventory, and physiological responding during scene presentation provided evidence for treatment efficacy. 12-mo follow-up indicated improved adjustment as supported by employment status, residential stability, emotional involvement, and self-report of anxiety, nightmares, and flashbacks.

Mild posttraumatic hypothermia reduces mortality after severe controlled cortical impact in rats

The effect of posttraumatic hypothermia (brain temperature controlled at 32 degrees C for 4 h) on mortality after severe controlled cortical impact (CCI) was studied in rats. Four posttraumatic brain temperatures were compared: 37 degrees C (n = 10), 36 degrees C (n = 4), 32 degrees C (n = 10), and uncontrolled (UC; n = 6). Rats were anesthetized and subjected to severe CCI (4.0-m/s velocity, 3.0-mm depth) to the exposed left parietal cortex. At 10 min posttrauma the rats were cooled or maintained at their target brain temperature, using external cooling or warming. Brain temperature in the UC group was recorded but not regulated, and rectal temperature was maintained at 37 +/- 0.5 degrees C. After 4 h, rats were rewarmed over a 1-h period to 37 degrees C, extubated, and observed for 24 h. In the 37 and 36 degree C groups, 24-h mortality was 50% (37 degrees C = 5/10, 36 degrees C = 2/4). In the 32 degree C group, 24-h mortality was 10% (1/10). In the UC group, brain temperature was 35.4 +/- 0.6 degrees C during the 4-h treatment period and 24-h mortality was 0% (0/6). Mortality was higher in groups with brain temperatures > or = 36 degrees C versus those with brain temperatures < 36 degrees C (50 vs. 6%, respectively; p < 0.05). Additionally, electroencephalograms (EEG) were recorded in subsets of each temperature group and the percentage of time that the EEG was suppressed (isoelectric) was determined. Percentage of EEG suppression was greater in the hypothermic (32 degrees C, n = 6; UC, n = 4) groups than in the normothermic (36 degrees C, n = 3; 37 degrees C, n = 6) groups (23.3 +/- 14.3 vs. 1.2 +/- 3.1%, respectively; p < 0.05). Posttraumatic hypothermia suppressed EEG during treatment and reduced mortality after severe CCI. The threshold for this protective effect appears to be a brain temperature < 36 degrees C. Thus, even mild hypothermia may be beneficial after severe brain trauma.     

Neural correlates of posttraumatic growth after severe motor vehicle accidents.

Frontal brain asymmetry has been associated with emotion- and motivation-related constructs. The authors examined the relationship between frontal brain asymmetry and subjective perception of posttraumatic growth (PTG) after severe motor vehicle accidents (MVAs). Eighty-two survivors of MVAs completed self-report measures of PTG, trait and state affect, and diagnostic interviews assessing clinical status, and underwent measurement of resting electroencephalographic activity. As predicted, increased relative left frontal activation was significantly related to PTG, even when statistically controlling for dispositional positive affect. The authors assume that approach-related motivational tendencies associated with higher relative left frontal brain activity may be involved in the process and outcome of PTG.

The role of vitreoretinal surgery in the treatment of posttraumatic macular hole

PURPOSE: Purpose of this study was to test a triple slice saturation recovery turbo FLASH sequence for myocardial perfusion imaging. In addition data-evaluation-tools for qualitative and quantitative perfusion parameters are presented and preliminary tested. MATERIAL AND METHODS: We examined 8 healthy volunteers and 4 patients with myocardial infarction. Parameters of the saturation recovery turbo FLASH sequence were as follows: TR = 2.5 msec, TE = 1.2 msec, alpha = 8 degrees, 3 slices, thickness 10 mm. For data analysis signal-intensity time curves were calculated pixel by pixel and evaluated for signal-intensity-increase over baseline and signal-intensity-upslope. Images were displayed color-coded. For quantitative data analysis we used the indicator dilution theory and developed a deconvolution algorithm which takes the arterial input function into account to calculate the myocardial mean transit time (MTT). RESULTS: The color-coded parametermaps showed uniform conditions in normal myocardium of volunteers, but reduced signal-intensity-increase over baseline and signal-intensity-upslope for infarcted areas in patients. The MTTs calculated using our algorithm were significantly shorter than those assessed with previous methods and matched better with values derived from literature. Infarcted areas show prolonged MTTs in comparison to normal myocardium. CONCLUSION: A triple slice saturation recovery turbo FLASH sequence is suitable for myocardial perfusion imaging. Color-coded parametermaps can visualize hypoperfused areas. For calculating myocardial MTTs using indicator dilution therapy a deconvolution algorithm is necessary.     

Prevention of cerebral edema and infarct in cerebral reperfusion injury by an antibody to interleukin-8

BACKGROUND: Indinavir, a protease inhibitor widely used to treat patients with HIV infection, has been associated with nephrolithiasis. Distinctive urinary crystals and a spectrum of urologic disorders were noted in patients receiving indinavir. OBJECTIVE: To determine the composition of urinary crystals and the frequency of asymptomatic crystalluria and urinary tract symptoms in patients receiving indinavir. PATIENTS: Patients with HIV infection who were enrolled in studies conducted at the National Institutes of Health. MEASUREMENTS: Microscopic urinalysis, high-performance liquid chromatography (HPLC) and mass spectrometry of urinary crystals and stones, and clinical evaluation of patients with urologic symptoms. RESULTS: Of 240 patients receiving indinavir, 142 provided urine specimens for analysis. Twenty-nine (20%) had crystals consisting of plate-like rectangles and fan-shaped or starburst forms. Mass spectrometry and HPLC confirmed that these crystals were composed of indinavir. Of 40 patients who were not receiving indinavir, none had similar crystals (P < 0.001). Nineteen of the 240 patients receiving indinavir (8%) developed urologic symptoms. Of these, 7 (3%) had nephrolithiasis and the other 12 (5%) had previously undescribed syndromes: crystalluria associated with dysuria and crystalluria associated with back or flank pain. Four of the patients with the latter syndrome had radiographic evidence of intrarenal sludging. CONCLUSIONS: Indinavir forms characteristic crystals in the urine. This crystalluria may be associated with dysuria and urinary frequency, with flank or back pain associated with intrarenal sludging, and with the classic syndrome of renal colic.     

Mindfulness in the treatment of posttraumatic stress disorder among military veterans.

How might a practice that has its roots in contemplative traditions, seeking heightened awareness through meditation, apply to trauma-related mental health struggles among military veterans? In recent years, clinicians and researchers have observed the increasing presence of mindfulness in Western mental health treatment programs. Mindfulness is about bringing an attitude of curiosity and compassion to present experience. This review addresses the above question in a detailed manner with an emphasis on the treatment of military veterans suffering from posttraumatic stress disorder (PTSD) and related psychopathology. In addition, the integration of mindfulness with current empirically supported treatments for PTSD is discussed with specific attention to directions for future research in this area.

Integrated (biopsychosocial) treatment in the family practice: a pregnant patient with a sacral tumor and severe posttraumatic stress disorder]

In a 25-year-old woman pregnant for the second time after a successful first pregnancy, a locally aggressive, invasive sacrum tumour was diagnosed. The execution of the necessary but potentially mutilating surgical procedures was seriously hampered even during the preparative phase, in spite of the conscious wish of the patient to comply, by her severe psychiatric problems (posttraumatic stress disorder with dissociative symptoms). The Psychiatric Consultation Service took over the case management and an integrated (biopsychosocial) diagnostic investigation was carried out, involving analysis of the problems on four system levels: the biological, the psychological, the social and the health care level. An integrated treatment plan was drafted. By collaboration of the entire multidisciplinary treatment team conditions were secured under which patient would let herself be treated. In this way she was enabled to undergo the necessary procedures, with good results.     

Hemodialysis in the treatment of severe hypercalcemia

Severe hypercalcemia is a life-threatening problem that requires prompt therapy. With the exception of diuresis, most forms of therapy are either ineffective, slow in action, or have major serious disadvantages. In some instances diuresis is relatively ineffective. As shown in this case report, hemodialysis with a dialysate low in calcium is rapidly effective in such instances and should be considered for patients with severe hypercalcemia while they are being prepared for surgery or while diagnostic studies are being performed.     

Role of surgical therapy in the treatment of refractory ascites

In 5-10% of cases ascites is not controlled by medical therapy and is defined refractory. These patients may be submitted to one of the four following surgical options: portal-systemic shunt, peritoneo-venous shunt, transjugular intrahepatic portal-systemic shunt, orthotopic liver transplantation. Although the portal-systemic shunt is efficient in clearing ascites, it does not improve the survival, which depends on liver function, and it is complicated by an important incidence of encephalopathy. Since the patients with refractory ascites and good hepatic risk are not usually many, it is possible to understand why derivative surgery has been disappointing with this indication. Although the peritoneo-venous shunt is associated with a significant rate of valve obstruction, it is an easy, effective and not expensive treatment. So, till now, it has been considered the first choice procedure of refractory ascites, if any situations, determinating the onset of postoperative complications, are not present. Recently a new method has been introduced in the therapy of portal hypertension, the transjugular intrahepatic portal-systemic shunt. This is a bloodless portal-systemic derivation and so it has caused great enthusiasm even if the available data are insufficient to give a definitive opinion on its role in management of ascites. Certainly the liver transplantation, which presents the great advantage to treat both the cirrhosis and its complications, seems to be the most rational therapy for these patients. However, at least for this moment, the well-known absence of organ donors makes still actual the palliative surgical measures.     

Use of midazolam in the treatment of refractory status epilepticus

Status epilepticus is an epileptic seizure that lasts at least 30 minutes or is repeated at sufficiently brief intervals to produce a continued epileptic condition lasting a total of 30 minutes without the patient fully regaining consciousness. Various combinations of anticonvulsant agents, including benzodiazepines, phenytoin, and phenobarbital, have been used to manage this condition. However, at least 9% of patients with generalized convulsive status epilepticus do not respond to conventional first-line agents, and additional intervention is required. Refractory status epilepticus refers to sustained seizures that do not respond to initial drug therapy and persist longer than 60 minutes. Reports on the response to first- and second-line agents suggest that the incidence of refractory status epilepticus is between 2000 and 6000 cases per year in the United States. Refractory status epilepticus is a major medical and neurologic emergency that requires immediate treatment to avoid significant morbidity and mortality. The anticonvulsive agent midazolam has proved to be effective, well tolerated, and fast acting when used to treat refractory status epilepticus in both adults and children. Its pharmacodynamic effects can be seen within 1 to 5 minutes of administration, and its anticonvulsive effects are apparent as early as 5 to 15 minutes after administration. This article reviews the pharmacology of midazolam and recent clinical reports on the drug's tolerability and effectiveness in the treatment of patients with refractory status epilepticus.
