Are comorbid anxiety disorders a risk factor for suicide attempts in patients with mood disorders? A two-year prospective study.

BACKGROUND: Comorbid anxiety disorders have been considered a risk factor for suicidal behavior in patients with mood disorders, although results are controversial. The aim of this two-year prospective study was to determine if lifetime and current comorbid anxiety disorders at baseline were risk factors for suicide attempts during the two-year follow-up. METHODS: We evaluated 667 patients with mood disorders (504 with major depression and 167 with bipolar disorder) divided in two groups: those with lifetime comorbid anxiety disorders (n=229) and those without (n=438). Assessments were performed at baseline and at 3, 12, and 24 months. Kaplan-Meier survival analysis and log-rank test were used to evaluate the relationship between anxiety disorders and suicide attempts. Cox proportional hazard regression was performed to investigate clinical and demographic variables that were associated with suicide attempts during follow-up. RESULTS: Of the initial sample of 667 patients, 480 had all three follow-up interviews. During the follow-up, 63 patients (13.1%) attempted suicide at least once. There was no significant difference in survival curves for patients with and without comorbid anxiety disorders (log-rank test=0.269; P=0.604). Female gender (HR=3.66, P=0.001), previous suicide attempts (HR=3.27, P=0.001) and higher scores in the Buss-Durkee Hostility Inventory (HR=1.05, P≤0.001) were associated with future suicide attempts. CONCLUSIONS: Our results suggest that comorbid anxiety disorders were not risk factors for suicide attempts. Further studies were needed to determine the role of anxiety disorders as risk factors for suicide attempts.

The effect of social adjustment and attachment style on suicidal behaviour.

OBJECTIVE: Prior studies examining the relationship between social adjustment and suicidal ideation or behaviour have not examined attachment. This study examines the effect of attachment on the association between current social adjustment and suicide attempt risk. METHOD: Attachment, social adjustment, and history of suicide attempt were assessed in patients participating in research on major depressive disorder (N = 524). Suicide attempters and non-attempters were compared with attachment style and social adjustment using hierarchical logistic regression models. The two factor scoring method of the Adult Attachment Scale (secure vs. avoidant) was utilized as each measures unique aspects of attachment. RESULTS: Anxious attachment (OR = 1.33; 95% CI = 1.016-1.728; P = 0.038) but not overall social adjustment (P = 0.14) was associated with a history of a past suicide attempt when both attachment and social adjustment were assessed in the same model. Among subtypes of social adjustment, work adjustment was associated with past history of suicide attempt (OR = 1.25; 95%CI = 1.019-1.540; P = 0.033). As impairment in work adjustment increased by 1 unit, the likelihood of reporting a suicide attempt increased by approximately 25%. There was no interaction between anxious attachment and work adjustment (P = 0.81). CONCLUSION: Anxious attachment and work adjustment warrant further study as potential treatment targets in depressed suicidal patients.

Clinical features of depressed patients with or without a family history of alcoholism.

OBJECTIVE: To compare clinical features of depressed subjects without alcoholism but with a family history of alcoholism to a depressed group without alcoholism and without a family history of alcoholism. METHOD: Clinical and demographic data of 209 depressed subjects without a history of alcoholism in first-degree relatives and 73 depressed individuals with a history of alcoholism in first-degree relatives were compared. Subjects with a personal history of alcoholism were excluded. RESULTS: Depressed subjects with a family history of alcoholism have a significantly higher prevalence of reported childhood physical and sexual abuse and post-traumatic stress disorder (PTSD), make more suicide attempts, and have greater intent to die at the time of their most lethal suicide attempt, compared to depressed subjects without a family history of alcoholism. CONCLUSION: Depressed patients with a family history of alcoholism are at greater risk for suicidal behavior and PTSD and may require more careful management.

Enlarged mesenteric lymph nodes in asymptomatic children: the value of the finding in various imaging modalities.

The purpose of this study was to determine the prevalence of enlarged mesenteric lymph nodes in asymptomatic children. We prospectively studied 189 consecutive asymptomatic children from the outpatients' nephrological clinics who were referred for abdominal ultrasound. For comparison, we retrospectively reviewed the abdominal CT studies of 99 children, performed following blunt abdominal trauma. The children of both groups were divided into four subgroups according to their ages. The size, the number and the morphology of mesenteric lymph nodes were assessed. On abdominal ultrasound, enlarged mesenteric lymph nodes were detected in 55 of 189 asymptomatic children (29.1%). The longitudinal diameter of the lymph nodes ranged between 5 mm and 19 mm. These lymph nodes were arranged in clusters (three to nine in number in a cluster). All the lymph nodes were oval-shaped, flattened, and without any discomfort following graded transducer compression. On abdominal CT, enlarged mesenteric lymph nodes were diagnosed in 28 of the 99 children (28.3%). These lymph nodes measured more than 5 mm and were arranged in clusters (three or more in number). In seven of these children associated minimal mural thickening of the terminal ileum was seen. The presence of enlarged mesenteric lymph nodes in asymptomatic children of all ages and in both sexes is a common, non-specific finding and should be evaluated only in the appropriated clinical context.

Lower cortisol levels in depressed patients with comorbid post-traumatic stress disorder.

Post-traumatic stress disorder (PTSD) is often comorbid with major depressive episodes (MDEs) and both conditions carry a higher rate of suicidal behavior. Hypothalamic-pituitary-adrenal (HPA) axis and serotonin abnormalities are associated with both conditions and suicidal behavior, but their inter-relation is not known. We determined cortisol response to placebo or fenfluramine in MDE, MDE and PTSD (MDE+PTSD), and healthy volunteers (HVs) and examined the relation of cortisol responses to suicidal behavior. A total of 58 medication-free patients with MDE (13 had MDE+PTSD) and 24 HVs were studied. They received placebo on the first day and fenfluramine on the second day. Cortisol levels were drawn before challenge and for 5 h thereafter. The MDE+PTSD group had the lowest plasma cortisol, the MDE group had the highest, and HVs had intermediate levels. There were no group differences in cortisol response to fenfluramine. Suicidal behavior, sex, and childhood history of abuse were not predictors of baseline or postchallenge plasma cortisol. Cortisol levels increased with age. This study finds elevated cortisol levels in MDE and is the first report of lower cortisol levels in MDE+PTSD. The findings underscore the impact of comorbidity of PTSD with MDE and highlight the importance of considering comorbidity in psychobiology.

Ultrasound features of spermatic cord hydrocele in children.

The aim was to evaluate the value of ultrasound diagnosis of spermatic cord hydrocele as a cause of inguinal swelling or mass in children. Clinical and ultrasound (US) findings and surgical procedures of 27 children with spermatic cord hydrocele were reviewed. All children, except one, were referred for US because of suspected inguinal hernia, hydrocele or inguinal mass. In one child, the US examination was performed to confirm the diagnosis of a spermatic cord hydrocele. An encysted hydrocele was diagnosed in 24 out of 27 cases, whereas a funicular type of spermatic cord hydrocele was found in the remaining 3 cases. Internal septa were seen within the fluid mass in four patients. 23 children underwent surgical exploration that confirmed the US diagnosis. Three children with encysted-type hydrocele were only followed clinically and by US, and one was lost from follow-up. US examination is a very sensitive and accurate method for diagnosis of this entity and for exclusion of other lesions in this region.

Minimal pelvic fluid in blunt abdominal trauma in children: the significance of this sonographic finding.

PURPOSE: The aim of this study was to evaluate the significance of the ultrasonographic finding of pelvic fluid after blunt abdominal trauma in children as a predictor of an abdominal organ injury. METHODS: The clinical and imaging data of 183 children with blunt abdominal trauma were reviewed retrospectively. All children had an abdominal sonography as the primary screening study. The ultrasound results were divided into 3 groups: group A, normal examination; group B, pelvic fluid only; group C, peritoneal fluid outside the pelvis. The results of the initial ultrasound examinations were compared with the findings of the CT scan, or a second ultrasound examination or the clinical course during the hospitalization. RESULTS: Group A included 87 children; group B, 57, and group C, 39. Four abdominal organ injuries were missed by the ultrasound examination. The sensitivity and specificity of the ultrasound examinations to predict organ injury in presence of peritoneal fluid outside the pelvis were, respectively, 89.5% and 96.6%; the positive and negative predictive value were 87.2% and 97.3%. No statistically significant difference was seen between group A and group B, whereas the presence of peritoneal fluid outside the pelvic cavity (group C) was associated strongly with an organ injury (P <.001). CONCLUSIONS: A normal ultrasound examination or the presence of pelvic fluid are associated with a low probability of an organ injury. In the presence of peritoneal fluid outside the pelvis, the probability of an organ injury is very high.

Pyelocalyceal diverticulum: the imaging spectrum with emphasis on the ultrasound features.

Clinical and imaging data of 11 patients with pyelocalyceal diverticulum were retrospectively examined. Four patients suffered from ipsilateral flank pain, one from recurrent urinary tract infection and the other six from unrelated symptoms. All patients underwent ultrasound as the initial imaging study. In two cases ultrasound was the only examination performed. Additional imaging studies were obtained in the other nine patients (abdominal radiography in six cases, intravenous urography (IVU) in five and CT in four). Ultrasound suggested the diagnosis of pyelocalyceal diverticulum in eight cases owing to the presence of echogenic and mobile material within the cyst-like lesion. In three cases the ultrasound appearance was similar and indistinguishable from a simple cyst and the diagnosis was made by another imaging study IVU in two cases and CT in one). We suggest that ultrasound examination is the best imaging method for the diagnosis of a pyelocalyceal diverticulum, and no further imaging modalities are required when mobile echogenic material is seen. In uncertain cases, another relatively inexpensive imaging study should be added such as abdominal radiography or IVU.

Medication supervision and adherence of persons with psychotic disorders in residential treatment settings: a pilot study.

BACKGROUND: Little is known about risk factors for and predictors of medication nonadherence within residential facilities. This pilot study examined the association between medication adherence and level of supervision and other environmental and clinical variables among patients with schizophrenia and related psychotic disorders living in supported housing. METHOD: A convenience sample of 74 adult residents with schizophrenia and related psychotic disorders (DSM-IV criteria) living in 4 supported housing facilities in New York City were assessed by their treating psychiatrist for medication cessation during the previous month. Demographic characteristics, medications, supervision, global function as measured by the Global Assessment of Functioning (GAF), and substance abuse were also assessed. A priori hypotheses were that regimen complexity would be directly and medication supervision would be inversely related to medication nonadherence. RESULTS: In multivariate models, lack of direct medication supervision, negative medication attitude, and lower GAF score were associated with increased medication nonadherence in the recent past. CONCLUSION: This pilot study suggests that direct supervision of medication is associated with better adherence in residential treatment settings. This finding is relevant for mental health service planners and clinicians working in these settings.

Malposition of catheters during voiding cystourethrography.

The aim of this study was to report catheter malposition during voiding cystourethrography. Eight hundred forty-three voiding cystourethrography (265 males and 578 females, aged 1 week to 12 years, mean age 2 years) were performed during a period of 4 years. The conventional standard procedure was applied. In 3 cases with passed history of urinary tract infection the catheter entered directly into the ureter. In all these cases the uretero-vesical reflux was present on the same side where the catheter entered. It appears that insertion of a catheter into the ureter is possible only in the presence of an anomaly or pathology at the vesicoureteric junction.

Delusions and suicidality.

OBJECTIVE: Delusions have been considered a risk factor for suicidal behavior. To determine whether specific delusion types are related to suicidal behaviors, the authors compared the clinical characteristics of patients with mood disorders and schizophrenia who did and did not have a history of suicide attempts. METHOD: After admission for inpatient or outpatient psychiatric treatment, 429 patients (ages 14-72 years; 47.1% male; and 73.0% Caucasian) were assessed with a structured clinical interview that generated axis I and II diagnoses. In addition, their psychiatric symptoms, history of suicide attempts, and overall functioning were rated. RESULTS: Data for three diagnostic subgroups (223 patients with major depression, 150 with schizophrenia, and 56 with bipolar disorder) were analyzed separately. Multivariate analyses did not find evidence of a relationship between delusions and history of suicidal ideation or suicide attempts in any of the diagnostic groups. CONCLUSIONS: This study did not find evidence that the presence of delusions distinguished persons with or without a history of suicide attempt.

Predictors of management problems in supported housing: a pilot study.

The study examined predictors of management problems among residents of a supported single room occupancy hotel (SRO) for persons with severe and persistent mental illness (SPMI). Case workers completed questionnaires on the prior six months. We found that medication-compliant residents without drug abuse were rarely disruptive, while those with co-morbid substance abuse were often disruptive. Residents non-compliant with medication also tended to cause management problems whether or not they abused drugs. Supported residences should be staffed and organized to minimize medication non-compliance and substance abuse which are associated with behavioral disruptiveness.

Iron overload following bone marrow transplantation in children: MR findings.

OBJECTIVE: The purpose of this study was to determine the incidence of post-transfusional iron overload in children after bone marrow transplantation by reviewing their magnetic resonance imaging (MR) findings. MATERIALS AND METHODS: We reviewed the abdominal MR studies of 13 children after autologous bone marrow transplantation. Nine of the children had also undergone MR prior to transplantation. Iron deposition in the liver, spleen and bone marrow was graded semi-quantitatively on both T1- and T2-weighted images. Serum ferritin levels and number of blood units given after bone marrow transplantation were recorded. RESULTS: None of the pre-transplantation MR studies revealed iron overload. After bone marrow transplantation, three children showed normal liver and spleen. Iron overload in the liver was noted in ten patients (77 %), six of whom also showed iron overload in the spleen (46 %) and five in the bone marrow (38.5 %). The degree of hepatic iron overload was correlated significantly and splenic iron overload was correlated weakly with the number of blood transfusions (P = 0.01 and P > 0.01, respectively), but neither was correlated with the serum ferritin level. CONCLUSION: Iron overload commonly accompanies bone marrow transplantation. The observed pattern of iron deposition, in which the spleen was uninvolved in 40 % of patients demonstrating iron overload, is not typical of post-transfusional hemochromatosis.

Predictors of missed appointments for psychiatric consultations in a primary care clinic.

OBJECTIVE: The purpose of the study was to determine predictors of missed appointments for psychiatric consultations among patients in a general medical clinic. METHODS: The charts of 180 patients consecutively referred for psychiatric consultations at a university-affiliated primary care clinic were reviewed. Ninety patients missed appointments for these consultations. Parametric and nonparametric tests were used to compare patients who missed and did not miss appointments on demographic and clinical variables, as well as measures related to patients' interactions with the clinic and the referring clinician. RESULTS: Logistic regression analysis revealed three significant predictors of missed appointments. Patients with mild distress and those with significant resistance to seeing a psychiatrist were more likely to miss appointments, as were those who had to wait longer between the referral and the appointment date. CONCLUSIONS: The results suggest that shortening the wait for a psychiatric consultation, reserving consultation for more severe cases, and working to reduce patients' resistance to consultation will reduce the number of missed appointments.

Definitive diagnosis of fracture-separation of the distal humeral epiphysis in neonates by ultrasonography.

Fracture-separation of the distal humeral epiphysis in neonates is difficult to diagnose radiologically because the cartilaginous epiphysis is radiolucent. We report a case in which fracture-separation of the distal humeral epiphysis in a neonate was diagnosed with the help of ultrasonography, which provided a clear delineation of the injury.

MRI in acute poliomyelitis.

MRI can be used in the diagnosis of anterior horn infection and for assessing the extent of disease. There are no specific MRI signs to differentiate between the various possible pathogens. This is demonstrated in the present case of poliomyelitis, in which MRI of the spine played an important role in establishing the diagnosis.

The natural history of osteonecrosis of the femoral head in children and adolescents who have Gaucher disease.

We reviewed the cases of eight patients (thirteen hips) with Gaucher disease who had had osteonecrosis of the femoral head and had been managed with bed rest and non-weight-bearing with crutches only in the symptomatic stage of the bone crisis. The mean age of the patients at the onset of the first crisis in each hip was ten years (range, six to fourteen years). The mean age at the most recent follow-up examination for the six living patients (ten hips) was twenty-three years (range, nineteen to thirty-three years). The Mose rating was good for one hip, fair for two, and poor for seven. Despite the over-all unfavorable radiographic ratings, the six patients were asymptomatic and did not need assistance with daily activities. There is no known treatment that effectively prevents the development of deformities of the femoral head. Thus, we recommend symptomatic management for osteonecrosis of the femoral head in Gaucher disease with bed rest and analgesics followed by non-weight-bearing on the involved limb, if it makes the patient more comfortable, during the symptomatic stage of bone crisis.

Tracheomegaly in Brachmann-de Lange syndrome.

Brachmann-de Lange syndrome is a well-described congenital disorder. Skeletal anomalies and respiratory infections are its hallmarks. To the known imaging signs, the authors add tracheomegaly, which has not been reported so far.
