Blunt Left Extrahepatic Bile Duct Injury: Case Report and Literature Review

Background  Extrahepatic biliary tract injuries following blunt abdominal trauma are very rare and pose a diagnostic and therapeutic challenge. Case Report  We report a case of blunt liver injury with left extrahepatic duct transection following a motor vehicle collision. Technetium 99m dimethyliminodiacetic acid scan confirmed a bile leak and endoscopic retrograde cholangiopancreatography (ERCP) diagnosed the injury of the left extrahepatic duct. Management was initially conservative, consisting of external drainage along with trials of stent placement. Ultimately, partial left hepatectomy was required to definitively treat the injury. Conclusion  In the setting of suspected biliary tract injury, early ERCP is essential to localize a leak and guide management decisions. In the event of a confirmed bile leak, a trial of nonoperative management consisting of endoscopic ductal decompression along with percutaneous drainage may initially be warranted although is not always successful.     

Gustatory cortex in the rat. II. Thalamocortical projections

The thalamic relay for lingual tactile, thermal, and gustatory sensibility was defined electrophysiologically in the rat. Subsequently, injections of tritiated leucine were centered in these functionally defined locations in separate series of rats. Following suitable survival periods, the brains were processed for autoradiographic tracing of axonal projections. After injections confined to the thalamic gustatory relay, labeled fibers terminated in agranular insular cortex. These results provide support for our previous experiments correlating neurophysiological localization of rat gustatory cortex and regional cytoarchitecture, and contrast with the traditional assignation of gustatory cortex to the granular insular area.     

Apoptosis in the traumatic and degenerative tears of human meniscus

The apoptotic bodies were observed aging in osteoarthritic cartilage and meniscus but there is still a lack of knowledge in the literature about the relationship between meniscal injury and apoptosis. The aim of this study is to investigate the apoptotic changes on meniscal tears caused by degeneration and trauma. Thirty-eight specimens of human meniscal tissues harvested from cadavers and patients were selected from groups below the age of 40. There were 14 normal meniscal tissues from cadavers in the control group. There were 24 meniscal tissues harvested from patients who had had arthroscopic operations for meniscal tear due to degeneration or trauma. The torn meniscal samples were divided into two groups according to their etiologies, either degenerative or traumatic. Apoptotic cells were investigated in each of the three groups in the histopathological examination. There was statistically significant difference among the groups according to apoptotic index (p < 0.01). The mean indexes of apoptosis in both groups of torn meniscus (group 2 = 0.497 and group 3 = 0.725) were significantly higher than that in the normal tissue (group 1 = 0.237) (p < 0.01) but the difference between groups 2 and 3 was not significant (p > 0.001). This study indicates that an increase in the amount of apoptosis appeared to have a close relationship with meniscal tear caused by either trauma or degenerative changes.     

Severe intestinal graft versus host disease after donor lymphocyte infusion; response to extracorporeal photochemotherapy.

We present a patient with acute myelogenous leukemia who developed severe acute intestinal graft versus host disease (GVHD) after donor lymphocyte infusion (DLI) following non-myeloablative allogeneic peripheral blood stem cell transplantation (allo-PBCT). One month after DLI, patient developed severe abdominal cramps, watery diarrhea without any signs or symptoms of the skin and liver GVHD. Treatment with steroid, cyclosporine A, tacrolimus and mycophenolat mofetil were not effective in controlling intestinal symptoms. Extracorporeal photochemotherapy (ECP), a recently used procedure in the treatment of GVHD was employed periodically and the symptoms subsided gradually. Acute GVHD after DLI may occur severely and atypically, but being limited to the intestine has rarely been reported.     

Positive Beliefs and the Likelihood of Successful Community Discharge From Skilled Nursing Facilities

ObjectivesTo examine the association of patient and direct-care staff beliefs about patients’ capability to increase independence with activities of daily living (ADL) and the probability of successful discharge to the community after a skilled nursing facility (SNF) stay.DesignRetrospective cohort study of SNF patients using 100% Medicare inpatient claims and Minimum Data Set resident assessment data. Linear probability models were used to estimate the probability of successful discharge based on patient and staff beliefs about the patient’s ability to improve in function, as well as patient and staff beliefs together. Estimates were adjusted for demographics, health status, functional characteristics, and SNF fixed effects.ParticipantsFee-for-service Medicare beneficiaries (N=526,432) aged 66 years or older who were discharged to an SNF after hospitalization for stroke, hip fracture, or traumatic brain injury.InterventionsNot applicable.Main Outcome MeasuresSuccessful community discharge (discharged alive within 90d of SNF admission and remaining in the community for ≥30d without dying or health care facility readmission).ResultsPatients with positive beliefs about their capability to increase independence with ADLs had a higher adjusted probability of successful discharge than patients with negative beliefs (positive, 63.8%; negative, 57.8%; difference, 6.0%, 95% confidence interval [CI], 5.4-6.6). This remained true regardless of staff beliefs, but the difference in successful discharge probability between patients with positive and negative beliefs was larger when staff had positive beliefs. Conversely, the association between staff beliefs and successful discharge varied based on patient beliefs. If patients had positive beliefs, the difference in the probability of successful discharge between positive and negative staff beliefs was 2.5% (95% CI, 1.0-4.0). If patients had negative beliefs, the difference between positive and negative staff beliefs was –4.6% (95% CI, –6.0 to –3.2).ConclusionsPatients’ beliefs have a significant association with the probability of successful discharge. Understanding patients’ beliefs is critical to appropriate goal-setting, discharge planning, and quality SNF care.     

Scrotal sonographic findings in equestrians.

OBJECTIVE: Sports-related injuries are among the major causes of testicular trauma. In this study, we aimed to determine sonographically whether chronic urogenital trauma during horse riding increases the prevalence of scrotal sonographic abnormalities. To our knowledge, there are no studies in the literature that have focused on this topic. METHODS: Group 1 included 26 male riders with a mean age +/- SD of 31 +/- 2.9 (range, 26-38) years and with a mean riding experience of 5 +/- 2.6 (range, 1-10) years, whereas group 2 included 26 healthy nonriding men with a mean age of 31 +/- 3.2 (range, 26-41) years. After the clinical evaluation, all patients underwent scrotal sonographic examination. RESULTS: The prevalence of overall scrotal sonographic abnormalities in group 1 was significantly higher than that in group 2 (77% versus 38%; P < .05). The detected sonographic findings in group 1 were varicocele (46%), hydrocele (19%), testicular cyst (4%), epididymal cyst (35%), testicular calcification (19%), epididymal calcification (8%), scrotal calculus (8%), and inhomogeneity of parenchymal echo texture (4%). However, only varicocele (19%), epididymal cyst (19%), testicular calcification (12%), and scrotal calculus (4%) were detected in group 2. Between the 2 groups, the difference was significant for varicocele prevalence (P < .05) and marginally significant for hydrocele prevalence (P = .051). CONCLUSIONS: We recommend scrotal sonographic examination of equestrians when they have a palpable mass or related symptoms, the etiology of which was found in our study to be closely related to horse riding.     

Psychiatric morbidity among cancer patients and awareness of illness

A significant proportion of cancer patients experience psychiatric morbidity. Potential predictors of psychiatric morbidity include patient disease-related factors and factors relating to the patients environment. The aim of this study was to investigate the prevalence of psychiatric morbidity and the relationship between the clinical or personal factors, especially psychiatric morbidity, and awareness of cancer diagnosis among a group of Turkish cancer patients. A total of 117 cancer patients were assessed using the Structured Clinical Interview for DSM-IV (SCID), the Hospital and Anxiety Depression Scale (HADS) and the General Health Questionnaire (GHQ). Of these patients, 30% had a psychiatric diagnosis. Adjustment disorders comprised most of the psychiatric diagnoses. Awareness of the diagnosis of cancer, history of previous psychiatric disorders, pain and stress factors were correlated with psychiatric morbidity. Of the 117 patients, 64 (54.7%) were unaware of the diagnosis of cancer. Most of the patients (67.9%) who were considered to be aware of the cancer diagnosis stated that they had guessed their illness from the treatment process or drug adverse effects. Psychiatric morbidity was significantly higher in the patients who knew that they had a cancer diagnosis (P=0.03). These findings suggest that the awareness of cancer diagnosis is related to the presence of psychiatric morbidity. In particular, the understanding of the diagnosis indirectly may be stressful to the patient because it arouses suspicion about the cancer and treatment, and consequently can lead to psychiatric disturbance. In Turkey honest disclosure of the true diagnosis is still not common for cancer patients and it seems to be essential to improve this situation.This paper was accepted as a poster presentation at the European Conference of Clinical Oncology (ECCO) Congress held in Copenhagen, 21–25 September 2003.
