A case of autoimmune pancreatitis associated with ulcerative colitis

A 31-year-old man was admitted to our hospital because of upper abdominal pain. He had been diagnosed with ulcerative colitis (UC) at age 28, but the disease has been in remission since then. On admission, he had slight fever, abdominal pain, and bloody stools six times a day, and the serum levels of pancreatic enzyme and IgG4 were elevated. Diffuse enlargement of the pancreas was detected by abdominal computed tomography; furthermore, narrowing of the main pancreatic duct was revealed using endoscopic retrograde cholangiopancreatography. Based on these findings, he was given a diagnosis of autoimmune pancreatitis (AIP) associated with UC. Both diseases improved without using steroids. After discharge, he has not had any recurrence of AIP or UC despite not being on steroid treatment, although the serum IgG4 level has shown a slight tendency to elevate.     

Immobilization-induced hypersensitivity associated with spinal cord sensitization during cast immobilization and after cast removal in rats

This study examined mechanical and thermal hypersensitivity in the rat hind paw during cast immobilization of the hind limbs for 4 or 8 weeks and following cast removal. Blood flow, skin temperature, and volume of the rat hind paw were assessed in order to determine peripheral circulation of the hind limbs. Sensitization was analyzed by measuring the expression of the calcitonin gene-related peptide (CGRP) in the spinal dorsal horn following cast immobilization. Two weeks post immobilization, mechanical and thermal sensitivities increased significantly in all rats; however, peripheral circulation was not affected by immobilization. Cast immobilization for 8 weeks induced more serious hypersensitivity compared to cast immobilization for 4 weeks. Moreover, CGRP expression in the deeper lamina layer of the spinal dorsal horn increased in the rats immobilized for 8 weeks but not in those immobilized for 4 weeks. These findings suggest that immobilization-induced hypersensitivity develops during the immobilization period without affecting peripheral circulation. Our results also highlight the possibility that prolonged immobilization induces central sensitization in the spinal cord.     

Comparison of characteristics and therapeutic efficacy in rheumatoid arthritis patients treated by rheumatologists and those treated by orthopedic surgeons under a team medicine approach at the same institute

The treatment of rheumatoid arthritis (RA) has improved dramatically with the advent of the latest generation of disease-modifying antirheumatic drugs. Despite these advances, in some patients inflammation is not diminished sufficiently to prevent irreversible musculoskeletal damage, thereby necessitating surgical intervention to reduce pain and improve function. For RA treatment, Japanese orthopedic surgeons also prescribe medication. In this study, we examined whether this Japanese system is effective for RA treatment. We analyzed the clinical condition of RA patients treated by rheumatologists and those treated by orthopedists in a linked registry study using information from a large observational cohort of RA patients followed every half year from 2000 to 2010 (the IORRA cohort). Two groups of patients were compared: patients treated by rheumatologists (rheumatologic group) and patients treated by orthopedists (orthopedic group). The results revealed that patients in the orthopedic group were older, more likely to be female, and had a longer disease duration than patients in the rheumatologic group. The proportion of patients with a history of joint surgery was also much higher in the orthopedic group than in the rheumatologic group. The average scores on the Japanese version of the Health Assessment Questionnaire, and the remission ratio determined using a Boolean-based definition gradually increased from 2000 until 2010, and these findings were consistently better in the rheumatologic group than in the orthopedic group. These data suggest that patients treated primarily by orthopedists are more likely to have long-standing RA compared to patients treated by rheumatologists. Therefore, it is critical for rheumatologists and orthopedists to complement each other medically in the treatment of RA patients.     

Improvement of endothelial function in parallel with the amelioration of dry cough and dyspnea due to interstitial pneumonia by intravenous cyclophosphamide pulse therapy in patients with systemic sclerosis: a preliminary report of two cases

Intravenous cyclophosphamide pulse therapy (IVCY) exerts its efficacy against interstitial lung disease (ILD) associated with systemic sclerosis (SSc) by restoring vascular injuries as well as aberrant immune activation. We recently experienced two patients with SSc-ILD in whom the values of brachial flow-mediated dilation (FMD) reflected the efficacy of IVCY. We herein report the details of these cases and discuss the potential of FMD to predict and evaluate the effect of IVCY on SSc-ILD.

The effect of a prostaglandin E1 derivative on the symptoms and quality of life of patients with lumbar spinal stenosis

Background

Quality of life (QOL) is a concern for patients with lumbar spinal stenosis (LSS). In this study, QOL was examined using the 5-item EuroQol (EQ-5D).

Methods

QOL and activities of daily living (ADL) were surveyed for 91 patients who visited 18 medical institutions in our prefecture and were diagnosed with LSS-associated intermittent claudication. A second survey was performed after ≥6 weeks for 79 of the subjects to evaluate therapy with limaprost (an oral prostaglandin E1 derivative) or etodolac (an NSAID). Symptoms, maximum walking time, QOL, ADL items, and relationships among these variables were investigated for all 91 patients. Leg pain, leg numbness, and low back pain while walking were surveyed by use of VAS scores (0–100).

Results

Leg pain, leg numbness, and low back pain while walking (VAS ≥25) were present in 83.5, 62.6, and 54.9 % of the patients in the first survey, and approximately half of the patients had a maximum walking time <15 min. The mean EQ-5D utility value for QOL was 0.59 ± 0.12. This value was significantly associated with maximum walking time (p = 0.030) based on classification of patients into groups with walking times <7.5, 7.5–15, 15–30, and >30 min, showing that maximum walking time affected health-related QOL. Of the 79 patients who completed the second survey, 56 had taken limaprost and 23 (control group) had received etodolac. Limaprost improved possible walking time, reduced ADL interference, and significantly increased the EQ-5D utility score, whereas no significant changes occurred in the control group. Maximum walking time was prolonged by ≥10 min and the EQ-5D utility value was improved by ≥0.1 points in significantly more patients in the limaprost group than in the control group.

Conclusion

According to the findings of this survey, at an average of 8 weeks after administration limaprost improved symptoms, QOL, and ADL in LSS patients whereas treatment with an NSAID reduced pain but did not have any other effects.     

Facial reanimation by transposition of the masseter muscle combined with tensor fascia lata,using the zygomatic arch as a pulley

We have created a new way of reanimating the face, involving transposition of the masseter muscle combined with tensor fascia lata, and using the zygomatic arch as a trochlea to reconstruct the inferior facial paralysis. We used it on five patients who had facial palsy after excision of malignant parotid tumours. The wide skin defect that exposed the masseter muscle after total parotidectomy was reconstructed with a free flap. This method differs from those of other methods of transposing the masseter muscle in that force is applied at an upper lateral angle. Our method provided dynamic raising of the upper lip, the corner of the mouth, and the nasolabial fold in four patients. We consider it to be useful, particularly for prompt surgical reconstruction of facial palsy after total parotidectomy with a wide defect in the skin of the cheek.
