Residual cognitive and psychosocial functional impairment in outpatients in Greece who responded to conventional antidepressant monotherapy treatments for major depressive disorder (MDD).

BACKGROUND: Patients with MDD may experience diverse residual symptoms after clinical response to antidepressant treatment. Among these symptoms, cognitive problems in executive functioning are prominent and make functional recovery largely an unmet need for MDD patients. In this study we assessed cognitive symptoms and functional impairment in patients with MDD responding to antidepressant treatment. METHODS: This was a national, multi-site, non-interventional, cross-sectional study of depressive symptomatology, cognitive performance and psychosocial functioning in Greek outpatients with MDD who had clinically responded to antidepressant treatment. Both clinician- and patient- rated measures were employed. Symptom remission was assessed with the Montgomery Asberg Depression Rating Scale (MADRS) total score (≤12) and functional recovery was assessed with the Sheehan Disability Scale (SDS) score (<6). RESULTS: 335 MDD patients participated in the study. After antidepressant monotherapy approximately 60 % of responders and 40 % of remitted patients did not meet the functional recovery criterion. More than 60 % of responders had concentration difficulties as assessed by MADRS item. Patient reported cognitive symptoms were statistically significantly associated with functionality (ß coefficient = 0.126, p-value = 0.027). LIMITATIONS: Non-interventional study design and lack of a control group or active comparator/reference. CONCLUSIONS: This study highlights the persistence of decreased cognitive performance, particularly in executive functioning in patients with MDD who have shown response and/or remission to antidepressant treatment. This appears to contribute to psychosocial functional impairment. Patient-reported cognitive and psychosocial functioning impairment should be included in routine clinical monitoring of outcomes in MDD treatments.

Laparoscopic low anterior resection for early rectal cancer.

INTRODUCTION: Early rectal cancer (ERC) is adenocarcinoma that has invaded into, but not extended beyond, the submucosa. Endoscopic or minimal access surgical procedures, such as laparoscopic resection, have emerged as a useful tool in the surgical treatment of such diseases. The aim of this study is to present and analyze the feasibility, the short- and long-term results of laparoscopic colorectal surgery (LCS) in patients with ERC. PATIENTS AND METHODS: Between 2002 and 4/2011, a total of 164 patients with colorectal cancer underwent laparoscopic surgery (LS). Of these, 7 patients (4.2%) had ERC and underwent laparoscopic anterior resection (LAR). The median follow-up was 41 months. RESULTS: The mean operative time was 2.5 h. None of the laparoscopic procedures was converted to open surgery. Liquids and solid food were started on median postoperative days 1 and 3, respectively. The median length of postoperative stay was 5 days. Postoperative complications occurred in 2 patients (28.5%), including wound infection in one patient (14.2%) and atelectasis in one patient (14.2%). None of the patients required an urgent re-operation. There was no mortality related to LS. CONCLUSIONS: LS for ERC can be used as a strategy sited between endoscopic mucosal resection and open anterior resection with beneficial long- and short-term results. It appears as a technically and oncologically safe procedure when performed by surgeons with sufficient experience in laparoscopic techniques.

Breast cancer metastatic to the rectum: a case report.

INTRODUCTION: Patients with breast cancer may present with systemic recurrence in any organ, primarily the bones, lungs, lymph nodes, liver, pleura, and adrenal glands. We report a case of rectal tumor, metastatic from breast cancer, which represents an unusual location of metastasis. CASE PRESENTATION: A 74-year-old woman, operated for lobular breast cancer 5 years ago, but not compliant with the annual follow-up, presented with severe constipation and pseudodiarrhea. Digital examination and anoscopy revealed a mass at the lower rectum, 2 cm distant from the anal verge. CT and MRI scan of the abdomen confirmed this finding and did not reveal metastatic lesions elsewhere. The patient underwent abdominoperineal resection. RESULTS: The postoperative period was uneventful, and the patient was discharged on the 7th postoperative day. The histopathological findings revealed rectal cancer, metastatic from the known invasive lobular breast cancer. CONCLUSIONS: Rectal metastasis from breast cancer is very rare. The presented case emphasizes the need to keep in mind this possibility and at all times associate the emergency condition with the related history of breast cancer.

Peak Width of Skeletonized Mean Diffusivity as Neuroimaging Biomarker in Cerebral Amyloid Angiopathy.

BACKGROUND AND PURPOSE: Whole-brain network connectivity has been shown to be a useful biomarker of cerebral amyloid angiopathy and related cognitive impairment. We evaluated an automated DTI-based method, peak width of skeletonized mean diffusivity, in cerebral amyloid angiopathy, together with its association with conventional MRI markers and cognitive functions. MATERIALS AND METHODS: We included 24 subjects (mean age, 74.7 [SD, 6.0] years) with probable cerebral amyloid angiopathy and mild cognitive impairment and 62 patients with MCI not attributable to cerebral amyloid angiopathy (non-cerebral amyloid angiopathy-mild cognitive impairment). We compared peak width of skeletonized mean diffusivity between subjects with cerebral amyloid angiopathy-mild cognitive impairment and non-cerebral amyloid angiopathy-mild cognitive impairment and explored its associations with cognitive functions and conventional markers of cerebral small-vessel disease, using linear regression models. RESULTS: Subjects with Cerebral amyloid angiopathy-mild cognitive impairment showed increased peak width of skeletonized mean diffusivity in comparison to those with non-cerebral amyloid angiopathy-mild cognitive impairment (P < .001). Peak width of skeletonized mean diffusivity values were correlated with the volume of white matter hyperintensities in both groups. Higher peak width of skeletonized mean diffusivity was associated with worse performance in processing speed among patients with cerebral amyloid angiopathy, after adjusting for other MRI markers of cerebral small vessel disease. The peak width of skeletonized mean diffusivity did not correlate with cognitive functions among those with non-cerebral amyloid angiopathy-mild cognitive impairment. CONCLUSIONS: Peak width of skeletonized mean diffusivity is altered in cerebral amyloid angiopathy and is associated with performance in processing speed. This DTI-based method may reflect the degree of white matter structural disruption in cerebral amyloid angiopathy and could be a useful biomarker for cognition in this population.

Perforated diverticulum of the caecum. A difficult preoperative diagnosis. Report of 2 cases and review of the literature.

BACKGROUND: Perforation of a solitary caecal diverticulum is a rare cause of acute abdomen and an uncommon differential diagnosis for acute appendicitis. Nine hundred cases have been described since Potiers' first description of perforated caecal diverticulum in 1912. METHODS: We describe 2 cases of perforated diverticulum of the caecum. The first patient was a 50-year-old man diagnosed by subsequent histology, and the second a 77-year-old woman diagnosed intra-operatively. Radiography, ultrasound and CT scan of the abdomen pointed at the diagnosis in the second case. A right hemicolectomy was performed. RESULTS: There were no complications, apart from a transient faecal fistula in the first patient managed conservatively. In both patients histology revealed a perforated caecal diverticulum. CONCLUSIONS: The surgeon must be familiar with the diagnosis and management of this rare, inflammatory benign caecal entity.

Synchronous and metachronous colorectal carcinoma.

BACKGROUND: Synchronous and metachronous colorectal carcinoma have an incidence of 2-10%. The purpose of the study was to evaluate the clinical characteristics, the accuracy of diagnostic examinations and the survival of these patients. METHODS: From 1970 to 1999, 1160 patients with colorectal cancer were admitted to our Department. During follow-up examination 50 patients (4.3%) were found to present with multiple primary colon cancers. Fifty-two per cent were synchronous and 48% metachronous tumours. RESULTS: The overall 5-year survival of the patients was 45.87%. Mortality was 10% for multiple primaries, while in patients with single cancer was 4.1%. The overall 5-year survival of the patients with multiple primaries tumours was 46.67%. CONCLUSIONS: Patients with colorectal cancer must be fully studied endoscopically. There has been an improvement in survival in recent years due to better surgical techniques, the introduction of more sophisticated examination methods and the meticulous follow-up of patients at risk.

Large bowel obstruction in women with pelvic malignancies. What is the primary?

BACKGROUND: Large bowel obstruction is occasionally the mode of presentation of advanced colorectal or pelvic malignancies, and a prognostic of poor survival. The choices of treatment range from palliative tube decompression to curative or palliative surgery. METHODS: Twelve out of 500 women with various malignancies and symptomatology of large bowel obstruction were studied. All patients required urgent exploratory laparotomies. RESULTS: The primary site was established intra-operatively to be the colon (2 cases), stomach (2 cases) and ovaries (2 cases). In the remaining 6 cases there was uncertainty about the origin of primary disease. Routine histology and immuno-histochemistry of the specimens revealed the origin of primary malignancy in all cases. CONCLUSIONS: Meticulous histological examination is essential for the establishment of correct diagnosis and selection of the best available treatment in women with pelvic malignancies, presenting with acute bowel obstruction.
