A case of strangulated bowel obstruction in which transabdominal ultrasound was useful for preoperative diagnosis.

A 74-year-old man presented to the emergency department with the chief complaint of abdominal pain. A computed tomography scan showed paralytic ileus. An ileostomy tube was placed, but the symptoms of bowel obstruction did not improve. Two days after admission, the patient's renal function deteriorated. Transabdominal ultrasound (TUS) showed linear high-intensity echoes consistent with a fibrotic band and microbubbles suggestive of circulatory disturbance in the dilated intestinal tract. Subsequent contrast-enhanced ultrasound revealed circulatory disturbance of the small bowel wall. Emergency surgery was performed under the diagnosis of strangulated ileus. Intraoperative examination revealed that the terminal ileum was strangulated by a fibrotic band from the retroperitoneum, which was confirmed by TUS. The fibrotic band was resected, the strangulation was released, and ileocecal resection was performed. Postoperatively, intestinal peristalsis was rapidly restored. TUS was able to depict the fibrotic band, which could not be detected by a computed tomography scan, allowing the patient to undergo immediate surgical treatment. We herein report this case of strangulated bowel obstruction in which TUS and contrast-enhanced ultrasound were useful in preoperative assessment of the patient's condition.

Appendiceal mucocele pathologically classified as appendiceal epithelial hyperplasia and preoperatively diagnosed by contrast-enhanced ultrasonography: A case report.

We report a patient with a mucocele with diffuse wall thickening diagnosed by transabdominal ultrasonography and contrast-enhanced ultrasonography. Transabdominal ultrasonography showed diffuse thickening of the entire appendix wall and an anechoic area that appeared to be fluid collected throughout the appendix lumen. However, the "onion skin sign" was not detected. Contrast-enhanced ultrasonography combined with superb microvascular imaging revealed abundant mucosal blood flow and no abnormal vascular network within the mucosa of the appendix wall. We preoperatively diagnosed a mucocele complicated by acute and chronic appendicitis, and ileocecal resection was performed. Macroscopic and microscopic findings of the resected specimens demonstrated that the appendiceal wall was diffusely thickened, with fibrosis and inflammatory cell infiltration, and that the appendiceal root rumen was narrowed with epithelial hyperplasia. No neoplastic changes were observed. The cause of the appendiceal mucocele was likely fibrosis and stenosis at the root of the appendix due to initial acute appendicitis.

[Three Cases of Appendiceal Goblet Cell Adenocarcinoma in Our Institution].

Appendiceal goblet cell adenocarcinoma(AGCA)is a newly designated pathological term adopted in the 5th edition of the WHO classification. It is synonymous with goblet cell carcinoid, which was previously categorized as a part of appendiceal carcinoid. However, since 2018, it has been classified as a subtype of adenocarcinoma. We have experienced 3 cases of this relatively rare tumor, of which 2 were initially diagnosed with acute appendicitis and were diagnosed with AGCA by pathological examination after an emergency appendectomy. Each of them underwent additional ileocolic resection with lymph node dissection as the second surgery. In the 3rd case, an appendiceal tumor was detected during preoperative examinations for an ovarian tumor. Staging laparoscopy revealed comorbid peritoneal dissemination, and only the appendix and right ovary were removed in the consecutive surgery. The ovarian tumor was pathologically diagnosed as a metastasis of AGCA. In this case, the introduction of oxaliplatin-based systemic chemotherapy after surgery achieved a complete response after more than 2 years. Although no recurrence has been observed in all 3 cases to date, AGCA is considered highly malignant compared to conventional appendiceal carcinoids. Therefore, it is crucial to practice multidisciplinary treatments, including sufficient radical surgery based on a precise diagnosis of AGCA, as is performed for advanced colorectal cancer.

Benefit of Continuation of Low-Dose Imatinib for Gastrointestinal Stromal Tumors despite Adverse Events with Regular-Dose Imatinib.

Tyrosine kinase inhibitors (TKIs) such as imatinib improve the prognosis of patients with gastrointestinal stromal tumors (GISTs). However, treatment options for GISTs are still limited, and the continuation of TKIs is difficult due to adverse events in some cases. The effectiveness of low-dose imatinib is unclear. We report 2 cases to show effectiveness of low-dose imatinib in patients with adverse events. The first case is a male in his early 60s with a history of intestinal GIST resection who was diagnosed with recurrent GIST with peritoneal dissemination. He was started on low-dose imatinib (300 mg) because of a history of subconjunctival hemorrhage after receiving postoperative imatinib. Follow-up contrast-enhanced ultrasonography revealed that the tumors had shrunk in size and number after 2 months of treatment with 300-mg imatinib. He continued this treatment and showed partial response for 8 months. The second case is a female in her late 70s with rectal GIST who was treated with imatinib 400 mg. Due to a severe skin lesion, she changed her treatment to sunitinib 2 months after initiation. However, new metastasis in the liver was confirmed after 4 months of administration of sunitinib. She underwent surgical esection of the rectal tumor to reduce the volume. After the surgery, low-dose imatinib (300 mg) with oral steroids was adopted. Follow-up confirmed the absence of recurrence at the rectum and no increase in hepatic tumor size for 18 months. Aggressive treatment with low-dose imatinib instead of discontinuation or alteration of treatment may benefit patients with unresectable and postoperative GISTs with sensible mutation to imatinib.

Prevalence and related factors of common mental disorders during pregnancy in Japan: a cross-sectional study.

BACKGROUND: Common mental disorders (CMD) during pregnancy can have a clearly harmful influence on both mothers and children. Some studies have reported related factors for mental disorders, such as region-specific background. This study examined the prevalence of CMD and its related factors in mid-pregnancy in Japan. METHODS: Pregnant women between 12 and 24 weeks gestation and aged ≥20 years were consecutively recruited at a maternity hospital in Japan between May 2014 and September 2014. CMD were diagnosed using the Mini-International Neuropsychiatric Interview (MINI), self-rated depressive symptoms were assessed using the Edinburgh Postnatal Depression Scale, and interpersonal traumatic experience was measured using the Life Events Checklist. RESULTS: Among 297 eligible pregnant women, 177 participated in the study. Two participants (1.1 %) met the criteria for major depressive disorder. The most frequent diagnosis was agoraphobia (n = 7; 3.9 %). Eleven participants (6.2 %) met the criteria for one or more diagnoses, with 2 participants having two mental disorders and 3 having three mental disorders. Six participants developed CMD after gestation. Logistic regression analysis revealed history of psychiatric disorder, past interpersonal traumatic experience, and feeling pressure to have a child were associated with CMD. CONCLUSION: These findings indicate a lower prevalence of CMD in mid-pregnancy in Japan than reported in most other countries. Besides the related factors reported previously, feeling pressure to have a child might increase risk for CMD among pregnant women in Japan. Asian cultural background might be related to the lower CMD prevalence and risk factors identified in this study.

[The Current Issues of Crime Victim Support from a Clinical Point of View].

This paper reviews part of an educational lecture at the 111th Annual Meeting of the Jap- anese Society of Psychiatry and Neurology (JSPN), under the identical title by the author. First, current victim support and treatment for victims at psychiatric services in Japan are reviewed. Second, introducing a case report of a rape victim diagnosed as PTSD, comments are made on symptoms, such as avoidance and emotional numbing as part of dissociation. It is common for clinicians, even for patients themselves, to fail to notice these symptoms. How to detect and treat these covert symptoms appropriately are discussed.

Complicated grief in those bereaved by violent death: the effects of post-traumatic stress disorder on complicated grief.

Violent death, such as homicide, accident, and suicide, is sudden, unexpected, and caused by intentional power, The prevalence of complicated grief among those bereaved by violent death is 12.5% to 78.0%. The factors affecting this prevalence rate are considered to be comorbid mental disorders, lack of readiness for the death, difficulty in making sense of the death, high level of negative appraisal about the self and others, and various social stressors. Post-traumatic stress disorder is, in particular, considered to contribute to the development of complicated grief by suppressing function of the medial prefrontal cortex and the anterior cingulate cortex, which works at facilitating the normal mourning process. An understanding of the mechanism and biological basis of complicated grief by violent death will be helpful in developing effective preventive intervention and treatment.

Complicated grief and related bereavement issues for DSM-5.

Bereavement is a severe stressor that typically incites painful and debilitating symptoms of acute grief that commonly progresses to restoration of a satisfactory, if changed, life. Normally, grief does not need clinical intervention. However, sometimes acute grief can gain a foothold and become a chronic debilitating condition called complicated grief. Moreover, the stress caused by bereavement, like other stressors, can increase the likelihood of onset or worsening of other physical or mental disorders. Hence, some bereaved people need to be diagnosed and treated. A clinician evaluating a bereaved person is at risk for both over-and under-diagnosis, either pathologizing a normal condition or neglecting to treat an impairing disorder. The authors of DSM IV focused primarily on the problem of over-diagnosis, and omitted complicated grief because of insufficient evidence. We revisit bereavement considerations in light of new research findings. This article focuses primarily on a discussion of possible inclusion of a new diagnosis and dimensional assessment of complicated grief. We also discuss modifications in the bereavement V code and refinement of bereavement exclusions in major depression and other disorders.

Clinical evaluation of paroxetine in post-traumatic stress disorder (PTSD): 52-week, non-comparative open-label study for clinical use experience.

AIM: The present study was a 52-week, non-comparative, open-label study of flexible dose paroxetine (20-40 mg) in 52 Japanese post-traumatic stress disorder (PTSD) patients in order to obtain clinical experience regarding efficacy and safety in regular clinical practice. METHODS: Efficacy was measured using the Clinician-Administered PTSD Scale One Week Symptom Status Version (CAPS-SX). RESULTS: The mean change from baseline in CAPS-SX total score was -19.1, -22.8 and -32.3 at weeks 4, 12 and 52, respectively, and that in the Clinical Global Impression (CGI) Severity of Illness score was -1.1 at week 12 and -1.7 at week 52. A total of 46.9% were CGI responders at week 12, while 67.3% were improved on the CGI at week 52. Of 52 subjects who entered into the drug treatment, 25 completed the study. Only one patient withdrew from the study due to lack of efficacy. In patients who were rated as 'moderately ill' or less at baseline, the proportion of CGI responders at end-point was higher at a dose of 20 mg/day than at higher doses, whereas in patients rated as 'markedly ill' or more, it was higher at 30 and 40 mg/day, suggesting that severely ill patients could benefit from higher doses. CONCLUSION: Paroxetine appeared generally tolerated in short- and long-term use, and the safety profile in this study was consistent with international trials and other Japanese populations (i.e. patients suffering from depression, panic disorder or obsessive-compulsive disorder). Although the study was not conducted in double-blind fashion, the current findings suggest that paroxetine may contribute to clinically meaningful improvement that is maintained during long-term use and is generally well tolerated.

The relationship between past traumatic experience and sickness absence.

BACKGROUND: Past traumatic experiences have been reported to lower stress tolerance, thereby increasing job strain. However, the relationship between past traumatic experiences and employee sickness absence is poorly understood. AIMS: This study explores the relationship between sickness absence and past traumatic experience with regard to the amount of time lapsed after the experience, job strain and other mental health states such as depression and anxiety. METHODS: A total of 3238 workers were assessed for levels of traumatic stress, depressive status, anxiety and job stress. RESULTS: Odds ratios of the presence of traumatic experiences to sickness absence, adjusted for sex, age and depressive and anxiety states, were presented according to the length of time that had passed since the traumatic events. The odds ratio in the 0-1 Years Group was 1.75 (p < 0.05), and the odds ratio for the 19+ Years Group was 1.46 (p < 0.1). CONCLUSIONS: Past traumatic events are related to sickness absence. Sickness absence resulting from a past traumatic experience is important with respect to industrial health.

[Posttraumatic stress disorder in victims of sexual assault--related to depression or physical symptoms].

UNLABELLED: To clarify the clinical characteristics of mental disorders in sexual assault victims, we investigated the victims focusing on PTSD, depression, physical symptoms, and their relationships. SUBJECTS: Participants were 46 treatment-seeking female victims of sexual assault who consulted four hospitals, one clinic and one psychological services center, between February 2000 and April 2001. The mean +/- SD age of the participants was 28.0 +/- 8.9 years, the mean +/- SD period from the traumatic event was 94.5 +/- 88.0 months. PTSD was diagnosed and evaluated using a structured interview (Clinician-Administered PTSD Scale for DSM-IV: CAPS). Depressive symptoms were assessed using Self-rating Depression Scales (SDS). Physical symptoms were assessed using the Physical symptom scale developed by the authors. RESULTS: Thirty-two participants (69.6%) met the criteria for PTSD in their current diagnosis, and 41 (89.1%) had the disorder at some point during their lives. SDS score and Physical symptom scale score of the PTSD group were significantly higher than those scores of the non-PTSD group. The SDS score correlated with the Avoidant-numbing score. The Physical symptoms scale score correlated with the Intrusion score and Hyperarousal score. We think that the PTSD group had the co-existing depression secondary to PTSD. Although previous studies have discussed the relationship between physical symptoms and Hyperarousal symptoms, this study suggested that physical symptoms were related to Intrusion symptoms as much as Hyperarousal symptoms. We found 2 patterns when PTSD patients reported physical symptoms related to Intrusion symptoms. The patterns were caused (1) by physiological reactivity on exposure to internal or external cues that symbolize an aspect of the traumatic event, and caused (2) by somatic reenactment symptoms. CONCLUSION: We discuss the importance for clinicians to distinguish Intrusion symptoms from physical symptoms as well as Avoidant-numbing symptoms from depressive symptoms on PTSD diagnosis. Because sexual assault victims have difficulty in talking about the traumatic experience, clinicians should pay attention to these findings in developing therapeutic plans for the victims.
