Occurrence of schizotypal and borderline symptoms in parasuicide patients: comparison between subjective and objective indices

Seventy-six patients were interviewed within a week of admission following a parasuicide episode. Axis II diagnosis on DSM-III was made for schizotypal, borderline, histrionic, and antisocial personality disorder. In addition patients completed a self-rating questionnaire, the Schizotypy Questionnaire of Claridge & Broks (1984), which assesses schizotypal and borderline personality traits. The objective and subjective indices of schizotypal and borderline symptoms correlated significantly but allocation of patients to a diagnosis missed several patients who nevertheless rated themselves as having a high frequency of these symptoms. There was an asymmetry of symptom pattern reminiscent of Foulds & Bedford's (1975) hierarchy model. The presence of schizotypal symptoms appeared to be higher in the hierarchy: they predicted borderline symptoms, but a high frequency of borderline symptoms did not necessarily predict schizotypy. We suggest that the occurrence of schizotypal symptoms should become a more explicit focus of clinical assessment and treatment of these patients, especially those who repeatedly harm themselves and we suggest ways in which cognitive therapies may be adapted to do this.

Laparoscopic versus open colorectal resection in the elderly population

Background

Elderly patients are often regarded as high-risk patients for major abdominal surgery because of a lack of functional reserve and associated medical comorbidities. The aim of this systematic review and pooled analysis was to review the current data published regarding the differences in operative outcomes of laparoscopic and open surgery in the elderly population.

Methods

A systematic literature search of Medline, Embase, Web of Science, and Cochrane databases was performed. Studies that compared outcome following laparoscopic and open colorectal resections in the elderly (≥70) population were included. Primary outcomes were operative death, anastomotic leak, pneumonia, length of hospital stay, and return to bowel function. Secondary outcomes were operative time, intraoperative blood loss, postoperative cardiac morbidity, ileus, and postoperative wound infection.

Results

The results of this systematic review and pooled analysis demonstrate the safety and potential benefits of laparoscopic colorectal resection in the elderly population. The latter include reduction in length of hospital stay, intraoperative blood loss, incidence of postoperative pneumonia, time to return of normal bowel function, incidence of postoperative cardiac complications, and wound infections.

Conclusion

The results of this pooled analysis demonstrate the potential short-term advantages of laparoscopic colorectal resection in the elderly population. Further studies are required to examine the long-term survival following laparoscopic and open colorectal resections in the elderly population.     

Laparoscopic Surgery for Solid Pseudopapillary Tumor of the Pancreas

Background and Objectives:

Solid pseudopapillary tumors of the pancreas are rare and occur most frequently in young women. They have an uncertain pathogenesis and unclear clinical behavior. Our aim was to evaluate the clinical presentation of solid pseudopapillary tumors and assess the efficacy of treatment with minimally invasive surgery.

Methods:

From March 1997 to February 2011, 13 of 273 patients who underwent laparoscopic procedures on the pancreas were found to have solid pseudopapillary tumors. There were 12 female patients and 1 male patient. The median age was 21 years (range, 15–77 years). Abdominal pain was the most common presenting symptom (n = 9). Tumors were incidentally found in 3 patients on computed tomography scans obtained for other reasons.

Results:

Enucleation of the tumor was performed in 4 patients, including 3 in whom the tumor was located in the head of the pancreas. Eight patients underwent distal pancreatectomy with splenectomy, whereas spleen-preserving distal pancreatectomy was performed in one case. The median tumor size was 6 cm (range, 1.5–11 cm), the median operative time was 197 minutes (range, 68–320 minutes), and the median blood loss was 50 mL (range, <50–750 mL). Distal resections were performed with a linear stapler. Four patients had postoperative complications. The median length of hospital stay was 5 days (range, 2–12 days). During a median follow-up period of 11 months (range, 3–121 months), no local recurrences or distant metastases were found.

Conclusion:

Laparoscopic resections and enucleations of solid pseudopapillary tumors of the pancreas can be performed safely and with adequate resection margins even if the tumors are located in the head of the organ.     

Eco-Friendly Incorporation of Crumb Rubber and Waste Bagasse Ash in Bituminous Concrete Mix

The consumption of waste materials in the construction sector is a sustainable approach that helps in reducing the environmental pollution and decreases the construction cost. The present research work emphasizes the mechanical properties of bituminous concrete mix prepared with crumb rubber (CR) and waste sugarcane bagasse ash (SCBA). For the preparation of bituminous concrete mix specimens with CR and SCBA, the effective bitumen content was determined using the Marshall Mix design method. A total of 15 bituminous concrete mix specimens with 4%, 4.5%, 5%, 5.5% and 6% of bitumen content were prepared, and the effective bitumen content turned out to be 4.7%. The effect of five different CR samples of 2%, 4%, 6%, 8% and 10% by weight of total mix and SCBA samples of 25%, 50%, 75% and 100% by weight of filler were investigated on the performance of bituminous concrete. A total of 180 samples with different percentages of CR and SCBA were tested for indirect tensile strength (ITS) and Marshall Stability, and the results were compared with conventional bituminous concrete mix. It was observed that the stability values rose with an increase in CR percentage up to 6%, while the flow values rose as the percentage of SCBA increased in the mix. Maximum ITS results were observed at 4% CR and 25% SCBA replacement levels. However, a decrease in stability and ITS result was observed as the percentages of CR and SCBA increased beyond 4% and 25%, respectively. We concluded that the optimum CR and SCBA content of 4% and 25%, respectively, can be effectively used as a sustainable alternative in bituminous concrete mix.     

Epileptic Activity Intrinsically Generated in the Human Cerebellum

Neoplastic or dysplastic neuronal tissue in the brain stem and cerebellum can become epileptogenic in pediatric patients. However, it is unknown whether such tissue may transform intrinsic properties of the human cerebellum, making it capable of generating epileptic population activity. We noninvasively detected epileptiform signals unaveraged in a pediatric patient with epilepsy due to a tumor in the middle cerebellar peduncle. Analysis of generators of the signals revealed that the cerebellum ipsilateral and contralateral to the tumor was the dominant interictal spike generator and could initiate ictal activity, suggesting that human cerebellum may become capable of intrinsically generating epileptic activity.
