The frequency of histopathological abnormalities in incidental appendectomy in urological patients: the implications for incorporation of the appendix in urinary tract reconstruction.

In 1980 Mitrofanoff described the use of the isolated appendix as an intermittent catheterization route to empty a continent urinary reservoir. The procedure was popularized and numerous variations on the same principle were reported. Presence of histopathological abnormalities in the appendix may limit its suitability for reconstructive purposes. We studied the frequency of incidental histopathological abnormalities in appendixes removed electively in 122 urological patients during a radical pelvic operation. The implications for incorporation of the appendix in urinary tract reconstruction are evaluated. A total of 38 patients (31.1%) had notable histological abnormalities of the appendix: 35 had fibrous obliteration of the lumen, 2 had carcinoid tumor and 1 had a mucocele of the appendix. The rate of abnormal appendixes was significantly higher in elderly patients (more than 70 years old). Incidental pathology of the appendix is a frequent finding that may affect the immediate results and the late outcome of urinary tract reconstruction using the appendix. When such strategy of urinary tract reconstruction is considered, potential histopathological abnormalities should be anticipated. The patients should be informed and aware of possible unexpected changes in the preplanned procedure, while the surgeon must be familiar with these alternative reconstructive methods.     

Functional and neuroanatomic correlations in poststroke depression: the Sunnybrook Stroke Study

BACKGROUND AND PURPOSE: The purpose of our study was to determine the functional and neuroanatomic correlates of poststroke depressive symptoms. METHODS: Patients with consecutive admissions to a regional stroke center for new-onset unilateral hemispheric stroke who met World Health Organization and National Institute of Neurological and Communicative Disorders and Stroke criteria were eligible for inclusion in a longitudinal study. Acutely, patients underwent CT scanning, and at 3 months and 1 year after stroke, depressive symptoms were assessed by using both the Montgomery-Asberg Depression Rating Scale and the Zung Self-Rating Depression Scale. The Functional Independence Measure (FIM) served as an indication of functional outcome and was obtained at 1 month, 3 months, and 1 year after stroke, along with other demographic information. The Talairach and Tournoux stereotactic atlas was used for the primary determination of CT lesion localization. Lesion proximity to the anterior frontal pole was also measured. RESULTS: Eighty-one patients participated in the longitudinal study. Stepwise linear regression analyses generated a highly significant model (F(3,76)=9.8, R(2)=28%, P<0.0005), with lower 1-month total FIM scores, living at home, and damage to the inferior frontal region predicting higher depression scores at 3 months. Similarly, lower 3-month total FIM scores correlated with higher 3-month depression scores, and lower 1-year total FIM scores correlated with higher 1-year depression scores. CONCLUSIONS: Functional measures correlated with poststroke depression across time and, together with neuroanatomic measures, predicted depressive symptoms longitudinally. Although inferior frontal lesion location, irrespective of side, appeared to play a role as a risk factor in this study, the degree of functional dependence after stroke imparted the greatest risk.     

Paranasal sinus inflammation and non-specific orbital inflammatory syndrome: an uncommon association

Objectives The aim of this study is to present a series of patients with orbital inflammatory symptoms associated with significant paranasal sinus inflammation, and to discuss the diagnostic and management modalities. Methods A retrospective, non-comparative, interventional case series of all patients diagnosed with orbital inflammatory syndrome and significant sinus inflammation, seen at two Orbital Units between January 1999 and October 2005. The clinical records of all patients were reviewed. Results Of 91 cases diagnosed with non-specific orbital inflammatory syndrome, six (6.6%, four males, two females mean age 51±17 years) had significant sinus inflammation. Symptoms and signs were periorbital swelling and erythema, proptosis, globe displacement and ocular motility restrictions with diplopia. On imaging, there was extraocular muscle enlargement and/or orbital fat haziness, as well as almost complete ipsilateral maxillary sinus opacification with varying degrees of opacification of adjacent sinuses. Sinus biopsy in four cases showed a non-specific inflammatory reaction. Treatment with steroids alone (four cases) or a combination of oral antibiotics and systemic steroids (two cases) resulted in resolution of signs and symptoms within 24–72 h. One case of recurrence was noted during a mean follow-up period of 9 months (range, 3–24 months), and this responded well to oral steroids. Conclusion Although uncommon, paranasal sinusitis can be associated with a non-specific orbital inflammatory syndrome. When an infectious etiology is excluded, systemic steroids may play a major role in the management of these patients and result in prompt resolution of orbital signs and symptoms.     

Multiple brain abscesses caused by Streptococcus bovis.

A case of multiple brain abscesses caused by Streptococcus bovis in a 28-year-old man is described. Infected bronchiectasis is presumed to be the source of infection. Streptococcus bovis infection is a rare cause of brain abscess. The aetiology and manifestations of this infection are discussed.
