Dietary intake of seaweed and minerals and prevalence of allergic rhinitis in Japanese pregnant females: baseline data from the Osaka Maternal and Child Health Study

PURPOSE: It may be worthwhile to assess the possible protective effect of the traditional Japanese diet on allergic disorders. This cross-sectional study investigated the relationship between dietary intake of seaweed, vegetables, fruit, antioxidants, fiber, and minerals and the prevalence of allergic rhinitis. METHODS: Study subjects were 1002 Japanese pregnant women. Allergic rhinitis (including cedar pollinosis) was defined as present if subjects had received drug treatment at some point during the previous 12 months. Information on dietary factors was collected by using a self-administered diet history questionnaire. RESULTS: Seaweed intake was associated independently with a decreased prevalence of allergic rhinitis. Significant inverse dose-response relationships were found between calcium and phosphorus intake and allergic rhinitis prevalence. There also was a tendency for an inverse association between magnesium consumption and allergic rhinitis. Additional adjustment for calcium or magnesium intake apparently did not influence the inverse association with seaweed consumption. Consumption of vegetables, fruit, vitamins C and E, fiber, and zinc showed no association with allergic rhinitis, whereas a significant positive relationship was observed between beta-carotene intake and allergic rhinitis. CONCLUSIONS: High dietary intake of seaweed, calcium, magnesium, and phosphorus may be associated with a decreased prevalence of allergic rhinitis.     

Efficacy of sitting balance training with delayed visual feedback among patients with stroke: a randomized crossover clinical trial

[Purpose] This study aimed to determine the effect of delayed visual feedback on the center of pressure and sitting balance in patients with stroke. [Participants and Methods] This was a single-blinded, randomized crossover trial. The duration of each intervention in real-time visual feedback and delayed visual feedback conditions while sitting on the platform was five days. We measured the center of pressure, function in sitting test, and functional independence measure for physiotherapy assessment. [Results] Twenty patients with stroke were included in this study. The delayed visual feedback condition improved the center of pressure for lateral distance, function in sitting test, and functional independence measure. The lateral center of pressure deviation increased significantly after 500 ms of intervention. The function in sitting test evaluated the interaction between pre- and post-training, and these conditions revealed that timing and condition factors contributed to the improvement. Sitting balance training affected the functional independence measure. [Conclusion] Sensory-motor and cognitive learning was facilitated through balance training with delayed visual feedback, and the internal model was updated with the efference copy of error correction. Sensory-motor feedback to visual stimulation can improve postural control, balance, and activities of daily living.     

Factors Associated with Pneumocystis jirovecii Pneumonia in Patients with Rheumatoid Arthritis Receiving Methotrexate: A Single-center Retrospective Study

Objective To investigate the risk factors for the development of Pneumocystis jirovecii pneumonia (PCP) in patients with rheumatoid arthritis (RA) undergoing methotrexate (MTX) therapy. Methods This single-center retrospective cohort study included consecutive patients with RA who received MTX for at least one year. The study population was divided into PCP and non-PCP groups, depending on the development of PCP, and their characteristics were compared. We excluded patients who received biologic disease-modifying anti-rheumatic drugs (DMARDs), Janus kinase inhibitors, and anti-PCP drugs for prophylaxis. Results Thirteen patients developed PCP, and 333 did not develop PCP. At the initiation of MTX therapy, the PCP group had lower serum albumin levels, a higher frequency of pulmonary disease and administration of DMARDs, and received a higher dosage of prednisolone (PSL) than the non-PCP group. A multivariate Cox regression analysis revealed that the concomitant use of PSL [hazard ratio (HR) 5.50, p=0.003], other DMARDs (HR 5.98, p=0.002), and serum albumin <3.5 mg/dL (HR 4.30, p=0.01) were risk factors for the development of PCP during MTX therapy. Patients with these risk factors had a significantly higher cumulative probability of developing PCP than patients who lacked these risk factors. Conclusion Clinicians should pay close attention to patients with RA who possess risk factors for the development of PCP during MTX therapy.     

Role of intrasplenic hepatocyte transplantation in improving survival and liver regeneration after hepatic resection in cirrhotic rats

We studied the effect of preoperative hepatocyte transplantation on the prevention of liver failure in cirrhotic rats after hepatic resection. Two groups of Lewis rats were rendered cirrhotic by i.p. injection of 1% dimethylnitrosamine and were subjected to 33% hepatectomy. Two days before the resection, 36 rats in group I received intrasplenic hepatocyte transplantation, and 25 rats in group II were given intrasplenic injection of normal saline as a control. By the end of the third postoperative day, the rats in group I had better survival and a better biochemical profile than those in group II. The liver growth rate and the labeling index of proliferating cell nuclear antigen (PCNA-LI) showed a steady rise in group I. Compared with group II, group I had a significantly lower transforming growth factor (TGF-beta1) level (p < 0.05). We conclude that preoperative intrasplenic hepatocyte transplantation improves survival and facilitates regeneration in cirrhotic rats after hepatic resection.     

Accessory mitral valve associated with aortic regurgitation in an elderly patient: report of a case

We encountered a 75-year-old man who complained of exertional dyspnea. An echocardiographic examination showed aortic regurgitation and a tumor in the left ventricular outflow tract. Under complete extracorporeal circulation, we surgically made an incision of the ascending aorta with a slight thickening of the aortic valve and an enlarged annulus. After excising the aortic valve, an examination of the subvalvular region revealed mitral valve-like tissue extending from the annular region of the right coronary cusp to the ventricular septum, while the chordae tendinae was attached to the septum. This issue was excised, and the aortic valve was replaced with a 27-mm SJM valve. The postoperative course was uneventful, and the patient was discharged in good condition on postoperative day 30. An accessory mitral valve is extremely rare. Since this indication for surgical treatment is associated with congenital heart disease or a left ventricular outflow tract obstruction, most patients are young. Our patient had no associated cardiac anomalies and no pressure gradient attributable to a left ventricular outflow tract obstruction. This accessory mitral valve was discovered during aortic valve replacement surgery. To our knowledge, our patient is the oldest reported with an accessory mitral valve to have undergone a surgical resection.     

A case of atypical aortic coarctation with mitral and aortic regurgitation and ascending aortic dilatation

A 67-year-old female presented with dyspnea on exertion as a chief complaint. Diagnosed as having severe mitral regurgitation, aortic regurgitation, dilatation of the ascending aorta and atypical coarctation due to aortitis syndrome, she underwent mitral valve replacement, aortic valve replacement, ascending aorta and hemiarch replacement and ascending aorta-abdominal aorta extraanatomical bypass in one stage. Pathologically, typical findings of aortitis syndrome were not observed in the wall of the ascending aorta and aortic valve, but cystic medionecrosis was noted in the wall of the ascending aorta. Follow-up observations are needed for the remaining aortic wall.     

Proximal oblique-domed osteotomy of the first metatarsal for the treatment of hallux valgus associate with flat foot: effect to the correction of the longitudinal arch of the foot

Introduction Flat foot and/or metatarsal primus varus are the major causes of hallux valgus, and it is important to correct these deformities in order to prevent the recurrence of this condition. We demonstrate the clinical and radiological assessment of the correction of hallux valgus, metatarsal primus varus, and flat foot after proximal oblique-domed osteotomy of the metatarsus with distal soft tissue reconstruction. Materials and methods Twenty-seven feet of 22 patients with moderate or severe hallux valgus who had undergone proximal oblique-domed osteotomy were studied. After the adductor hallucis tendon was cut at the attachment of the proximal phalanx and at the sesamoid bone, the osteotomy was performed 3 cm dorsal-distal to the metatarsocuneiform joint to transfer distal fragment approximately 5 mm in the plantar direction, and rotated laterally decreasing the first–second intermetatarsal angle to 5 degrees. Results The mean AOFAS score was 54.1 ± 2.8 points at pre-operation and 92.8 ± 4.8 points at the most recent follow-up (P < 0.0001). Significant improvement was seen between the hallux valgus angle (P < 0.0001), first–second intermetatarsal angle (P < 0.0001), first–fifth intermetatarsal angle (P < 0.0001), talar pitch (P = 0.0032), and calcaneal plantar angle (P = 0.0327) before surgery and at one year after surgery. The average improvement of the talar pitch and calcaneal plantar angle was 2.6 ± 1.4 and 2.4 ± 1.5 degrees, respectively. Conclusion This study suggest that proximal oblique-domed osteotomy of the metatarsal as a surgical procedure for the treatment of moderate or severe hallux valgus with flat foot can be recommended to correct the longitudinal arch of the foot and the first–second intermetatarsal angle.     

Intraarterial chemotherapy for uterine cervical adenocarcinoma: evaluation of its efficacy as neoadjuvant therapy

We performed preoperative intraarterial chemotherapy in twenty cases of uterine cervical adenocarcinoma (stage Ib: 2, II: 15, III: 3) and evaluated the efficacy of this therapy. The dosages used were 75-120 mg of CDDP, 10-20 mg of MMC and 30-60 mg of EPIR. These drugs were administered by intraarterial one-shot infusion twice every three weeks. In five cases, complete response (CR) of the primary lesion was confirmed by histologic examination. There were no cases of CR inpatients with well differentiated adenocarcinoma. Stage reduction was achieved in all cases except three. In all but one case, more than 50% volume reduction was recognized on MR images. These results were not significantly different from those in cases of uterine cervical squamous cell carcinoma in which we performed this therapy. Therefore, we concluded that intraarterial chemotherapy is highly effective and should be carried out as neoadjuvant therapy for advanced uterine cervical adenocarcinoma.     

The role of postoperative radiotherapy in non-small cell lung cancer; a retrospective analysis of our experience

Sixty-one patients with completely resected non-small cell lung cancer followed by postoperative radiotherapy were retrospectively reviewed. Forty-six patients were male and 15 were female. Ages ranged 34-79 (median 64) years. Squamous cell carcinoma (scc) in 28, adenoca. in 31, large cell ca in 1 and adenoid cystic ca. in 1. Pathological stage was IIA in 1, IIB in 9, IIIA in 41 and IIIB in 10. Over-all 5-year survival rate (OS) was 56.0%, and 5-year disease-free survival rate (DFS) was 39.7%. For IIB, IIIA, IIIB patients, OS were 77.8%, 55.4%, 24.0% respectively. According to purpose of radiotherapy, patients divided into 3 types as local invasion (LI) group (T3-4N0-1, n = 12), lymphnode metastases (LN) group (T1-2N2-3, n = 38) and both advanced (BA) group (T3-4N2-3, n = 8). OS were 71.6%, 50.7%, 46.9% and DFS were 68.6%, 31.0%, 42.9% respectively. In LN group, half of patients with scc had no relapse, but about half of non-scc had distant metastases. All N2 patients divided 2 types as single-station N2 and multi-station N2. OS were 71.8%, 40.0% and DFS were 53.5%, 21.1% respectively. DFS was significantly different (p = 0.04). The advantage was remarkable in patients with scc-single-station N2 (OS was 88.9%, DFS was 77.8%). The effectiveness of postoperative radiotherapy is not showed, but our results suggest the possibility for existence of subgroup benefited from postoperative radiotherapy.
