Successful resection of liver metastasis detected by exacerbation of skin symptom in a patient with dermatomyositis accompanied by rectal cancer: a case report and literature review

Abstract Background Dermatomyositis (DM) is a rare syndrome that belongs to the group of idiopathic inflammatory myopathies. The association between DM and malignancy is well recognized, and the severity of DM symptoms has been linked to the progression of metastatic disease. Case presentation We report the case of a 42-year-old man that was diagnosed with dermatomyositis (DM) and rectal cancer. Proctectomy was performed, and DM symptoms were resolved postoperatively. One year and 9\ua0months after the surgery, liver metastasis occurred accompanied by the exacerbation of DM symptom. Partial resection of the liver was performed, and postoperative course was uneventful. DM symptoms improved postoperatively, and no evidence of cancer recurrence or DM symptoms was observed 2\ua0years after the second surgery. To date, few reports have described recurring cases of DM accompanied by colorectal cancer in detail. We reviewed four similar cases that were reported poor prognoses with treatment resistance. However, our case report demonstrates good long-term results with resection of metastatic lesion. Conclusions It is important to check the exacerbation of DM symptoms, as this symptom sometimes preceded cancer relapse during the follow-up of our patient with DM and colorectal cancer

Serotonin Differentially Regulates Short- and Long-Term Prediction of Rewards in the Ventral and Dorsal Striatum

BACKGROUND: The ability to select an action by considering both delays and amount of reward outcome is critical for maximizing long-term benefits. Although previous animal experiments on impulsivity have suggested a role of serotonin in behaviors requiring prediction of delayed rewards, the underlying neural mechanism is unclear. METHODOLOGY/PRINCIPAL FINDINGS: To elucidate the role of serotonin in the evaluation of delayed rewards, we performed a functional brain imaging experiment in which subjects chose small-immediate or large-delayed liquid rewards under dietary regulation of tryptophan, a precursor of serotonin. A model-based analysis revealed that the activity of the ventral part of the striatum was correlated with reward prediction at shorter time scales, and this correlated activity was stronger at low serotonin levels. By contrast, the activity of the dorsal part of the striatum was correlated with reward prediction at longer time scales, and this correlated activity was stronger at high serotonin levels. CONCLUSIONS/SIGNIFICANCE: Our results suggest that serotonin controls the time scale of reward prediction by differentially regulating activities within the striatum

A 10-year follow-up study of completers versus dropouts following treatment with an integrated cognitive-behavioral group therapy for eating disorders

Abstract Background Cognitive-behavioral therapy (CBT) has been recommended for the treatment of eating disorders, and group therapy is known to have certain advantages over individual therapy. The aim of the current study was to compare the 10-year prognosis of patients who completed integrated group CBT with those who dropped out and to examine the effect of completion of group CBT on the prognosis. Methods The participants were 65 adult patients with eating disorders. All patients were women and Japanese. The average age (19–37) of the patients was 25.1 ± 3.8 years, and the average body mass index (BMI) was 17.7 ± 2.0. We conducted integrated group CBT with the patients and compared eating disorder symptoms, mood states, coping styles, and self-esteem before and after therapy. Furthermore, we compared clinical features and the 10-year prognosis of patients who completed the treatment and those who dropped out. Results After 10 sessions of group therapy, Eating Attitudes Test scores, Profile of Mood States depression scores, and Coping Inventory for Stressful Situations emotion-oriented scores decreased, while Rosenberg’s Self-Esteem Scale scores increased. Regarding the results of the 10-year follow up, the completer group had more patients with a good prognosis. In contrast, the dropout group had more patients with a poor prognosis. Conclusions Those who completed the integrated group CBT had a good prognosis. Group therapy gives the patients an opportunity to form peer relationships, and helps them to develop communication and socialization skills. Furthermore, in the group therapy sessions, the patients develop self-awareness by listening to other members of the group and they also develop interpersonal relationships. This effect may be temporary, but experience of group therapy may provide hope for the patient and increase the chance of the patient continuing treatment.

Anticipation of affective images and event-related desynchronization (ERD) of alpha activity : An MEG study

We investigated the event-related power decrease (event-related desynchronization: ERD) of the alpha bands associated with the anticipation of affective images. Participants (n = 19) were presented with emotionally positive or negative images under different anticipatory conditions, and their brain responses were recorded using magnetoencephalography (MEG). In the Affective Cue conditions, the cue stimulus indicated the emotional valence (positive or negative) of the image. In the Null Cue condition, the cue stimulus did not include any information about the valence of the image, and in the No Cue condition, the affective image was presented without a preceding cue. The cues in the affective and null conditions were followed by emotional images. During the anticipation period for the affective image, the alpha ERD preceding an anticipated negative image was larger than that preceding an anticipated positive image; this effect had an occipital dominance. Furthermore, during the anticipation period, the lower-2-alpha ERD of the right frontal area showed the same result. These results demonstrate that anticipation of negative stimuli induced alpha ERD in both the visual and the right frontal cortex, indicating that top-down modulation may be provided by the right frontal cortex to the visual cortex

Hemorrhagic Cholecystitis in a Patient on Maintenance Dialysis

The present paper describes a case of hemorrhagic cholecystitis in a patient on maintenance dialysis. The patient presented with right upper quadrant abdominal pain. Computed tomography revealed swelling of the gallbladder, high- and isodensity contents of the gallbladder, and high-density stone in the gallbladder neck. He was hospitalized for suspected acute cholecystitis. After hospitalization, his levels of total bilirubin, aspartate aminotransferase, and alanine aminotransferase increased. T2-weighted magnetic resonance imaging showed low-intensity contents expanded to include a wide area from the common bile duct to the cystic duct and gallbladder neck. Endoscopic retrograde cholangiopancreatography revealed clotting from the duodenal papilla. After cannulation of the bile duct, old blood and pus began to flow from the mammary papilla, and an endoscopic nasobiliary drainage tube was placed. After his liver function had improved, the patient underwent laparoscopic cholecystectomy. His sample revealed that the gallbladder was filled with blood clots and stones. His postoperative course was uneventful and he was discharged on day 19 after the procedure. Although hemorrhagic cholecystitis is rare, it should be considered as a differential diagnosis for patients on dialysis who have acute abdominal symptoms

Prognostic Nutritional Index Predicts Treatment Outcomes following Palliative Surgery for Colorectal Adenocarcinoma

Objectives: Palliative surgeries such as stoma creation and bypass are effective for relieving symptoms related to incurable abdominal malignancies; however, these methods are controversial in patients with severe metastatic disease or poor pre-surgical health. The aim of this study was to examine the clinical significance of the prognostic nutritional index (PNI) in evaluations for palliative surgery. Methods: We retrospectively analyzed data from 37 patients who underwent palliative surgery for histologically-proven colorectal adenocarcinoma from 2009 to 2015. We investigated both risk factors for postoperative complications and prognostic factors. We used a PNI cutoff value of 40, as defined by previous studies. Results: The reason for surgery was stenosis in 18 patients, obstruction in 12, fistula in 5, and bleeding in 2. Bypass was performed in 10 cases, ileostomy in 5, and colostomy in 22. Postoperative morbidity and mortality occurred in 9 and 2 patients, respectively. Median overall survival time was 8.9 months. Only low PNI correlated with postoperative complications at trend-level (p=0.07), and the 2 patients with mortality were classified as PNI-low. The presence of ascites (p=0.003) and PNI (p=0.02) were identified as independent prognostic factors. Conclusions: PNI could be used as an objective marker for deciding whether to proceed with palliative surgery, independent of the extent of metastatic disease

Distal Gastrectomy for Symptomatic Stage IV Gastric Cancer Contributes to Prognosis with Acceptable Safety Compared to Gastrojejunostomy

Background: The prognostic prolongation effect of reduction surgery for asymptomatic stage IV gastric cancer (GC) is unfavorable; however, its prognostic effect for symptomatic stage IV GC remains unclear. We aimed to compare the prognosis of gastrectomy and gastrojejunostomy for symptomatic stage IV GC. Methods: This multicenter retrospective study analyzed record-based data of patients undergoing palliative surgery for symptomatic stage IV GC in the middle or lower-third regions between January 2015 and December 2019. Patients were divided into distal gastrectomy and gastrojejunostomy groups. We compared clinicopathological features and outcomes after propensity score matching (PSM). Results: Among the 126 patients studied, 46 and 80 underwent distal gastrectomy and gastrojejunostomy, respectively. There was no difference in postoperative complications between the groups. Regarding prognostic factors, surgical procedures and postoperative chemotherapy were significantly different in multivariate analysis. Each group was further subdivided into groups with and without postoperative chemotherapy. After PSM, the data of 21 well-matched patients with postoperative chemotherapy and 8 without postoperative chemotherapy were evaluated. Overall survival was significantly longer in the distal gastrectomy group (p = 0.007 [group with postoperative chemotherapy], p = 0.02 [group without postoperative chemotherapy]). Conclusions: Distal gastrectomy for symptomatic stage IV GC contributes to prognosis with acceptable safety compared to gastrojejunostomy
