Objective: The purpose of this study was to investigate the immediate effects of manual traction of the hip joint on joint space width (JSW) on asymptomatic subjects.Methods: Asymptomatic, healthy male volunteers (n = 15), aged 25 to 34 years were included in this study. Three radiographs were obtained with the subjects in the supine position, before and after loading with 10% of his body weight, and after manual traction on only the right hip joint. Joint space width was measured by a radiologist at the point described by Jacobson and Sonne-Holm.Results: There were significant changes in JSWon the right hip joint and left hip joint between the baseline (before loading) and immediately after loading. We also observed a significantly increased JSW on only the right hip joint between periods that followed loading and manual traction on the right hip joint. There was no significant change in JSW on the left hip joint between periods that followed loading and manual traction on the right hip joint.Conclusions: The results of this study suggest that a significant increase in JSW in young, healthy male patients can occur immediately after manual traction of the hip joint. © 2014 by National University of Health Sciences.

Purpose: To assess efficacy of the conservative management of patients with congenital dacryocystocele. Materials and methods: This was a retrospective case series involving six sides of five infants with a dacryocystocele treated at Osaka Kaisei Hospital, Osaka, Japan. The conservative management protocol consisted of the application of warm compresses and massage over the mass, with the addition of antibiotics when dacryocystitis developed. Patient age at the time of resolution, presence of retrograde outflow of contents of dacryocystoceles from the puncta, and development of dacryocystitis were recorded. Results: The dacryocystocele was unilateral in four patients and bilateral in one patient. A nasal cyst was present in four patients without respiratory distress. The median patient age at the time of the diagnosis was 7 days (range 2-10 days). Conservative management was selected in all patients, and the dacryocystocele was resolved in all patients at a median patient age of 14.5 days (range 11-105 days). Two sides developed dacryocystitis, which resolved in a few days with antibiotic treatment. In those two sides, rupture of the dacryocystoceles to the common canaliculus with retrograde discharge of the contents from the puncta before the dacryocystitis developed was noted. For the other four treated sides, no such discharge or development of dacryocystitis was observed. Conclusion: The findings of this study show that a dacryocystocele has a good chance of resolving spontaneously with conservative management and careful observation, and that rupture of the dacryocystocele to the common canaliculus might be an important precursor of dacryocystitis. © 2014 Mimura et al.

A 24-year-old man underwent surgery for a fractured left clavicle and received an interscalene brachial plexus block for intraoperative and postoperative analgesia. After injection of 40 ml 0.5% ropivacaine and confirmation of analgesia, general anesthesia was induced and maintained with propofol. Although the operation was completed uneventfully, the patient was restless and there was limb twitching during emergence from anesthesia. Ropivacaine-induced toxicity was suspected, and a dose of 100 ml 20% lipid emulsion was infused intravenously. The symptoms of toxicity disappeared, and there was full recovery of consciousness within 5 min. Plasma concentrations of total and protein-unbound ropivacaine measured 2 h 20 min after local injection were 1.99 and 0.13 μg/ml, respectively. After infusion of lipid emulsion, the ropivacaine concentrations decreased to 1.72 and 0.05 μg/ml, respectively. The patient had no pain, and neurological examination revealed sensory loss around the clavicle. The patient was discharged without any complications. © 2011 Japanese Society of Anesthesiologists.

Purpose: To evaluate the effect of the postoperative administration of rebamipide ophthalmic suspension on the success rate of lacrimal stent intubation (LSI) for the treatment of primary acquired nasolacrimal duct obstruction (PANDO). Methods: This comparative interventional cohort study investigated 110 consecutive patients with PANDO who were treated with LSI and followed up for 12 months postoperatively at one institution. LSI was performed by one surgeon, and all patients received identical postoperative care. Among the total 110 patients, 71 underwent LSI with postoperative administration of rebamipide ophthalmic suspension, and 39 underwent LSI without administration of the suspension. Data related to patient age, gender, laterality, and postoperative administration of rebamipide ophthalmic suspension were collected and used as independent variables, and logistic regression analyses were performed to compare the anatomical success rate at 12 months postoperatively between patients with and without postoperative administration of the suspension. Results: The anatomical success rate of LSI in patients with and without postoperative administration of rebamipide ophthalmic suspension was 90.1 and 69.2 %, respectively. A comparison of these success rates showed statistical significance, in that the rate of treatment success was higher in PANDO patients who underwent LSI with postoperative administration of the suspension [odds ratio (OR), 3.37; P < 0.05]. Conclusions: The findings of this study show that postoperative administration of rebamipide ophthalmic suspension increases the rate of anatomical success in patients who undergo LSI for the treatment of PANDO. © 2015, Springer-Verlag Berlin Heidelberg.

Purpose: To study the indications for and effectiveness of Nunchaku-style silicone tube intubation (NSTI) in treating primary acquired lacrimal drainage obstruction (PALDO). Methods: In this interventional cohort study, 235 consecutive patients in 1 institution who had complete lacrimal obstruction were investigated. Of those, 212 PALDO patients were enrolled, and 156 of the PALDO patients ultimately satisfied our treatment protocol and were then followed up for 12 months postsurgery. Patients without dacryocystitis underwent NSTI, while those with dacryocystitis underwent NSTI or endonasal dacryocystorhinostomy (EN-DCR) using the NST as a stent. The tubes were left in place for 8 weeks, and all patients received identical postoperative care. Resolution was deemed as patency assessed by irrigation. Logistic regression analyses were performed to compare the success of NSTI for upper (puncta and canaliculus) and lower (lacrimal sac and nasolacrimal duct) obstruction, NSTI for lower obstruction with and without dacryocystitis, and NSTI and EN-DCR for lower obstruction with dacryocystitis. Results: Comparison of the success rates at 12 months postsurgery showed significance as follows: treatment with NSTI was more successful for upper obstruction (94.6 %) than for lower obstruction (71.4 %) [odds ratio (OR) 8.23; P < 0.01]; treatment with NSTI was more successful for lower obstruction without dacryocystitis (82.9 %) than for dacryocystitis (52.4 %) (OR 4.96; P < 0.05); and treatment with EN-DCR (95.5 %) was more successful than NSTI (52.4 %) for treating lower obstruction with dacryocystitis (OR 16.99; P < 0.001). Conclusions: NSTI is effective for treating PALDO; however, EN-DCR is more effective for treating PALDO cases complicated by dacryocystitis. © 2015, Japanese Ophthalmological Society. Source
