Nightmare disorder, dream anxiety, and subjective sleep quality in patients with borderline personality disorder

Aims:  The aims of the present study were to examine the rate of nightmare disorder (ND) and to determine the levels of dream anxiety and subjective sleep quality in patients with borderline personality disorder (BPD). Another aim was to determine whether dream anxiety was associated with childhood trauma, dissociative experiences, and subjective sleep disturbance in BPD patients. Finally, the hypothesis as to whether BPD patients with ND exhibited a more severe clinical profile than those without ND, was also tested.
Methods:  A total of 88 borderline patients and 100 age- and sex-matched healthy control subjects were assessed using the Structured Clinical Interview for DSM-III-R Personality Disorders, Structured Clinical Interview for DSM-IV Axis I Disorders, Van Dream Anxiety Scale, Pittsburgh Sleep Quality Index, Dissociative Experiences Scale, and Traumatic Experiences Checklist. Subjects with codiagnoses that could affect sleep were not included.
Results:  BPD patients suffered a significantly greater rate of nightmares, elevated levels of dream anxiety, and disturbed sleep quality than did controls. In the borderline group, heightened dream anxiety was correlated with higher rates of early traumatic experiences and dissociative symptoms, and impaired sleep quality. Furthermore, borderline patients with ND exhibited greater psychopathology as compared to those without ND in terms of several clinical characteristics.
Conclusions:  The present study provides support for a strong association between BPD, distressing nightmares, and subjective sleep quality. Recognition and management of dream and sleep disturbances in BPD patients might lead to improvements in their global clinical picture.     

Assessment of Endothelial Function in Alzheimer's Disease: Is Alzheimer's Disease a Vascular Disease?

OBJECTIVES: To compare endothelial function of people with Alzheimer's disease (AD) with that of people without. DESIGN: Case-control study. SETTING: Geriatric medicine outpatient clinic of a university hospital. PARTICIPANTS: Twenty-five patients with AD who were free of vascular risk factors and 24 healthy elderly controls were enrolled. Exclusion criteria were diabetes mellitus, hypertension, dyslipidemia, evident stroke, smoking, documented coronary artery disease, history of myocardial infarction, heart failure, acute or chronic infection, malignancy, peripheral artery disease, renal disease, rheumatologic diseases, alcohol abuse, and certain drugs that may affect endothelial function. Both groups underwent comprehensive geriatric assessment and neuropsychiatric assessment. MEASUREMENTS: Endothelial function was evaluated according to flow-mediated dilation (FMD) from the brachial artery. RESULTS: Mean age +/- standard deviation was 78 +/- 5.9 in the group with AD (11 female and 14 male) and 72.1 +/- 5.8 in the control group (9 female and 11 male). Multiple linear regression analysis revealed that FMD was significantly lower in patients with AD (median 3.45, range 0-7) than controls (median 8.41, range 1-14) (P < .001), independent of age. It was also found that FMD values were inversely correlated with the stage of the disease as determined according to the Clinical Dementia Rating scale (r=-0.603, P < .001). CONCLUSION: Endothelial function is impaired in patients with AD. Endothelial function was worse in patients with severe AD. These findings provide evidence that vascular factors have a role in the pathogenesis of AD.     

Removal of a bent inflatable femoral nail: a case report

Intramedullary nailing is the gold standard for the treatment of diaphyseal femoral fractures. Bending of the nail secondary to trauma is a rare complication encountered in unhealed and comminuted fractures. A 23-year-old man was admitted with refracture of the right femoral shaft and a 32-degree bending of an inflatable intramedullary nail due to a fall, two months after the initial surgical treatment. The nail was first straightened by exerting an external force, which decreased the angulation to 10 degrees. Then, the fracture site was opened, the lateral wall of the nail was drilled, and one of the four metal bars of the nail was cut. This allowed complete straightening of the nail by the same maneuver and its removal. A new inflatable intramedullary nail was placed and union was achieved after four months. Tools that may be necessary to cut the nail partially or totally should be made available for removal of bent nails.     

Horner's syndrome due to jugular venous ectasia

Horner's syndrome may be caused by a lesion anywhere along the three-neuron pathway from the hypothalamus to the eye. This syndrome has been reported secondary to numerous causes to date. In this paper, we describe an extremely rare case of Horner's syndrome due to jugular venous extasia demonstrated by computed tomography and intravenous digital subtraction angiography.     

Successful treatment of invasive pulmonary aspergillosis in an immunocompetent host

Immunocompromised individuals are susceptible to pulmonary Aspergillus infection, but invasive Aspergillus infection is extremely rare in the presence of normal immunity. A case of invasive pulmonary aspergillosis in an immunocompetent 57-year-old female who was successfully treated with liposomal amphotericin-B is reported here.     

Color Doppler tissue imaging to evaluate left atrial appendage function in mitral stenosis

Two-dimensional color Doppler tissue imaging (CDTI) has so far been used, in general, to evaluate ventricular function. This study examined if the left atrial appendage tissue velocity could reproducibly be measured with CDTI and if they have any predictive value for left atrial appendage (LAA) function and former thromboembolism. Thirty-six patients (24 women, 12 men; mean age 45 +/- 12 years; 18 AF; 11 former thromboembolic stroke) with mitral stenosis undergoing transesophageal echocardiography were examined with CDTI. Peak systolic tissue velocity (m/sec, peak systolic velocity [PSV]) was measured at the tip of the LAA in the basal short-axis view. LAA flow emptying (LAAEV) and filling (LAAFV) velocities (m/sec) were also recorded 1 cm immediately below the orifice of the appendage. Interobserver and intraobserver variabilities were determined for the PSV. LAA ejection fraction was measured by Simpson's method. Mitral regurgitation, AF, transmitral mean gradient, left ventricular ejection fraction, mitral valve area, and left atrial diameter were used as a covariant for adjustment. The intraobserver and interobserver correlation coefficients for the PSV using CDTI was 0.64 and 0.60, respectively (bothP = 0.01). LAAEV(0.29 +/- 0.09 vs 0.19 +/- 0.04, P = 0.001)and LAA ejection fraction(44 +/- 12 vs 29 +/- 14, P = 0.004)were found to be significantly decreased in the patients with decreased PSV (<0.05 m/sec), even after adjustment. The decreased PSV was positively correlated with the low LAAEV (<0.25 m/sec) and history of thromboembolism (r = 0.59, r = 0.38, respectively), and remained a significant determinant of the low LAAEV (OR 50.03, CI 1.46-1738.11,P = 0.02), but not of history of thromboembolism (OR 4.29, CI 0.52-35.01,P = 0.08) after adjustment. In conclusion, these results suggest that CDTI provides a reproducible method for quantification of contraction at the tip of the LAA. Decreased PSV may be predictive of poor LAA function.
