Intramedullary nailing of tibial shaft fractures in the semi-extended position using a suprapatellar approach: A retrospective case series.

Tibial shaft fractures are extremely common injuries. High rate of union, acceptable alignment in all planes, and a low complication rate have been reported when diaphyseal fractures are treated by intramedullary nailing. However, knee pain after tibial nailing has historically been problematic. While the exact aetiology of the knee pain is still unknown, surgical approach relative to the patellar tendon, nerve transection, violation of the fat pad or joint capsule as well as nail diameter and implant prominence have been claimed as possible causes. Therefore, establishing an appropriate starting point remains a crucial step in the surgical procedure. Recently, suprapatellar nailing in the semi-extended position has been suggested as a safe and effective surgical technique. Literature is lacking on this topic, therefore the present article discusses clinical outcomes of 25 patients treated by suprapatellar nailing at 2 years follow up and a literature review.

Personality disorders in bipolar and depressive disorders.

The association of mood disorders with personality disorders (PDs) is relevant from a clinical, therapeutic and prognostic point of view. To examine this issue, we compared the prevalence of DSM-III-R personality disorders assessed with SCID-II in patients with depressive (n = 117) and bipolar (n = 71) disorders both recovered from a major depressive index episode that needed hospital admission. PDs prevalence and comorbidity with axis I were calculated. Avoidant PD (31.6%) (O.R. = 1.7, C.I. = 1.06-2.9. P < 0.01), borderline PD (30.8%) and obsessive-compulsive PD (30.8%) were the most prevalent axis II diagnoses among patients with depressive disorder. In bipolar disorder group, patients showed more frequently obsessive-compulsive PD (32.4%), followed by borderline PD (29.6%) and avoidant PD (19.7%). Avoidant PD showed a trend toward being significantly more prevalent among depressives (P < 0.07). A different pattern of PDs emerges between depressive and bipolar patients.

Behavioral neurodevelopment abnormalities and schizophrenic disorder: a retrospective evaluation with the Childhood Behavior Checklist (CBCL).

This study is a retrospective report of childhood and adolescence neurobehavioral assessment in patients with schizophrenia and their healthy siblings using the Childhood Behavior Checklist (CBCL). The CBCL ratings were obtained from retrospective maternal reports, for five age periods (birth to 3years, 4-7years, 8-11years, 12-15years and 16-18years) in a sample of 32 patients with schizophrenia. The patients showed a variety of childhood and adolescence behavioral problems when compared with their siblings, and the various types of problems differed in the developmental course of the disease. Cluster analysis was conducted on the childhood premorbid behavior ratings for the schizophrenic patients, and two subgroups emerged: a cluster with an initially low level of behavioral abnormalities (B.A. ) that increased over the years, and a cluster with a high level of B.A. that remain relatively stable until early adulthood. The latter group showed more severe current negative symptoms.

[Personality disorders prevalence study among inpatients with mood disorders, psychoactive use disorders and anxiety disorders]. / Valutazione della prevalenza di disturbi di personalità in una popolazione di pazienti psichiatrici ospedalizzati per disturbi dell'umore, disturbi da uso di sostanze psicoattive e disturbi d'ansia.

OBJECTIVE: The aim of this study was to asses type and prevalence of Personality Disorders (PDs) and their patterns of comorbidity with Axis I disorders in a sample of psychiatric inpatients. SETTING: The sample consisted of 300 subjects admitted to a psychiatric unit on a voluntary bases for an index episode. The study was conducted over a period of 12 months, from 1.11.1997 to 31.10.1998. MAIN OUTCOME MEASURES: The Italian version of SCID-II-PQ (Structured Clinical Interview for DSM-III-R personality disorders, with Personality Questionnaire--PQ--a self report questionnaire). RESULTS: More than half the patients had at least one personality disorder. The mean of disorders per patient was 2.83 +/- 1.93 (+/- SD). The most prevalent Axis II disorders were Borderline PD (30.7%), Obsessive-compulsive PD (30.7%) and Avoidant PD (25.3%). Women were significantly more likely than men to meet criteria for Dependent PD and Avoidant PD. Man showed significantly more frequently than women Antisocial PD. Significant associations (p < 0.05) were found for comorbidity of Mood Disorders and Avoidant PD, and for Psicoactive Use Disorders and Antisocial PD. CONCLUSIONS: Our study confirms the high prevalence of PDs in psychiatric inpatients and showe some interesting associations between Axis I and Axis II disorders. These results can't be generalized to outpatients because our clinical sample involved mainly severely ill inpatients, but they raise questions about the exact nature of PDs and of the relationship with Axis I disorders. Further research involving outpatients and general population is needed to examine factors that could affect development and course of Personality Disorders.

Patterns of comorbidity among DSM-III-R personality disorders.

The aim of this study was to examine patterns of comorbidity among personality disorders (PDs) in a sample of 156 psychiatric inpatients. PDs were assessed with Semistructured Clinical Interview for DSM-III-R Personality Disorders. To determine significant co-occurrence among axis II diagnoses, odds ratio and the percent of co-occurrence of pairs of disorders were calculated. Both statistical methods revealed high rates of comorbidity: significance association was found for 36 pairs of disorders using the percent of co-occurrence, and for 22 pairs of disorders using the odds ratio. These results support the concept of 'apparent comorbidity' for most PDs, deriving from conceptual and definitional artifacts or from a 'state-biasing effect'. In light of these observations, a categorical approach to PDs, resulting in a list of diagnoses, appears useless in psychiatric practice. A dimensional classification is probably better suited for PDs, improving the understanding of personality psychopathology and its clinical implications.

Neuromorphological abnormalities in schizophrenic patients with good and poor outcome.

OBJECTIVE: The present study was designed specifically to assess the relationship between brain morphology and outcome in schizophrenia. METHOD: Fifty-six schizophrenic patients and a matched group of 32 healthy subjects were studied with magnetic resonance (MR) imaging scans. Clinical assessment included the Krawiecka-Manchester Scale (K-MS) and the Outcome scale by Strauss and Carpenter. RESULTS: Along several neuromorphological measures the patients differed from controls only for right and left ventricular volumes. The 'poor outcome' patients had a left and right ventricular enlargement when compared to the 'good outcome' patients and healthy controls. A regression analysis showed that right ventricle volume, left temporal lobe volume and left hippocampal volume entered into the regression equation, accounting for a 27% of the outcome measure. CONCLUSION: The outcome does not seem to be predicted by one particular morphological site but involves different brain regions; however, the ventricular enlargement identifies a subgroup of patients with poor outcome.

Pattern of comorbidity among anxious and odd personality disorders: the case of obsessive-compulsive personality disorder.

The aim of this study was to examine the pattern of comorbidity among obsessive-compulsive personality disorder (OCPD) and other personality disorders (PDs) in a sample of 400 psychiatric inpatients. PDs were assessed using the Semistructured Clinical Interview for DSM-III-R Personality Disorders (SCID-II). Odds ratios (ORs) were calculated to determine significant comorbidity among OCPD and other axis II disorders. The most elevated odds ratios were found for the cooccurrence of OCPD with cluster A PDs (the "odd" PDs, or paranoid and schizoid PDs). These results are consistent with those of previous studies showing a higher cooccurrence of OCPD with cluster A than with cluster C ("anxious") PDs. In light of these observations, issues associated with the nosologic status of OCPD within the Diagnostic and Statistical Manual of Mental Disorders clustering system remain unsettled.

Spatial working memory assessment by a visual-manual delayed response task: a controlled study in schizophrenia.

'Working memory' dysfunction has been proposed as a central cognitive feature in schizophrenia. To further explore this issue we developed a computerized easy and fast to administer test using the standard keyboard as visual-manual subject-computer interface along a delayed-response paradigm. The test has been administered to 25 patients who met the DSM-III-R criteria for schizophrenia and 25 healthy control subjects matched as possible for sex. The data confirm the visuo-spatial 'working memory' dysfunction in schizophrenic patients. The test maintains the discriminative capacity of similar previously devised tasks with the advantages of being usable on almost every standard computer and shorter and more acceptable for severely disabled patients also. The test can be considered an useful tool to study the 'working memory' impairment in the cognitive deficit of schizophrenia.

[The use of the Italian version of the Parental Bonding Instrument (PBI) in a clinical sample and in a student group: an exploratory and confirmatory factor analysis study]. / Utilizzazione della versione italiana del Parental Bonding Instrument (PBI) in un campione clinico ed in un campione di studenti: uno studio di analisi fattoriale esplorativa e confermatoria.

OBJECTIVE: The aim of this study was to verify the construct validity of the Italian version of Parental Bonding Instrument (PBI) a questionnaire which estimates the parental style as reported by the son or daughter. METHOD: The questionnaire was administered to a group of 102 students (62 males and 40 females) attending University of L'Aquila and to a sample of 128 patients (76 males and 52 females) consecutively admitted to a psychiatric unit for an index episode. We compared the means of the two factors (care, protection) separately for each parent in the two groups using a t-test for independent samples. After having estimated the internal consistency of items of each scale by calculating Cronbach's coefficient alpha, a factor analysis was performed for students and patients to find the structural factors of the questionnaire; then, we conducted a confirmatory factor analysis of the PBI items, for the students only, to evaluate the fit of the real items to models proposed in the literature. RESULTS: The Italian version of the Parental Bonding Instrument, demonstrated the ability to discriminate between patients and controls; it showed an high internal consistency. The factor analysis identified a two factors solution which accounted for 44.6% and 44.3% of the variance of the mother's and father's PBI scores respectively for the group of students and it identified two factors which accounted for 49.3% and 46.6% of the variance in the group of patients. CONCLUSIONS: The psychiatric patients showed a low "care"-high "protection" confirming an association between the "affectionless control" pattern and psychiatric disorders.
