We reviewed reports about the postoperative course of hemifacial spasm (HFS) after microvascular decompression (MVD), including in our own patients, and investigated treatment for delayed resolution or recurrence of HFS. Symptoms of HFS disappear after surgery in many patients, but spasm persists postoperatively in about 10–40%. Residual spasm also gradually decreases, with rates of 1–13% at 1 year postoperatively. However, because delayed resolution is uncommon after 1 year postoperatively, the following is advised: (1) In patients with residual spasms after 1 year postoperatively (incomplete cure) or who again experience spasm ≥ 1 year postoperatively (recurrence), re-operation is recommended if the spasms are worse than before MVD. (2) When re-operation is considered, preoperative magnetic resonance imaging (MRI) findings and intraoperative videos should be reviewed to ensure that no compression due to a small artery or vein was missed, and to confirm that adhesions with the prosthesis are not causing compression. If any suspicious findings are identified, the cause must be eliminated. Moreover, because of the risk of nerve injury, decompression of the distal portion of the facial nerve should be performed only in patients in whom distal compression is strongly suspected to be the cause of symptoms. (3) Cure rates after re-operation are high, but complications such as hearing impairment and facial weakness have been reported in 10–20% of cases, so surgery must be performed with great care. 相似文献

Background and Aims: Rolipram is a specific type IV phosphodiesterase inhibitor that suppresses the activity of immune cells and the production of pro-inflammatory cytokines. In this study, we assessed the effect of rolipram on acute liver injury using thioacetamide (TAA)-induced liver injury in rats as a model.
Methods: Rats were treated with rolipram (0.5–5 mg/kg, intraperitoneally) or vehicle and injected 30 min later with TAA (100 mg/kg, subcutaneously). Serum transaminase concentrations and tumor necrosis factor-α (TNF-α), interleukin 1β (IL-1β) and growth related oncogene/cytokine-induced neutrophil chemoattractant-1 (GRO/CINC-1) levels were measured and livers were examined for microscopic changes. Dose-dependent protection against TAA liver injury was based on transaminase levels and inflammatory cytokine production, and was measured 9 h after TAA when the peak release of cytokines occurred.
Result: Rolipram suppressed liver injury based on serum aspartate transaminase (AST), alanine transaminase (ALT) and histology and reduced TNF-α, IL-1β and GRO/CINC-1 levels. Rolipram, at doses of 0.5–5 mg/kg, suppressed serum transaminase and TNF-α production in a dose-dependent manner, and these effects were significant at doses of 2.5 and 5 mg/kg.
Conclusion: In our rodent model of acute liver injury, rolipram clearly reduced liver damage and inhibited pro-inflammatory cytokine production. These results suggest that specific type IV phosphodiesterase inhibitors, such as rolipram, have potent hepatoprotective effects that are associated with suppressing inflammatory cytokine production. 相似文献

A unique case of carcinosarcoma of the prostate detected in a 71-year-old man is presented. Pelvic exenteration was performed, and the resected prostatic mass was found to consist of two histologically distinct elements; adenocarcinoma and sarcoma with focal osteosarcomatous element. The patient is still alive with neither metastasis nor recurrence. This is the 42nd case of carcinosarcoma of the prostate to be reported in the literature. 相似文献

Infants with neuroblastoma are known to have a favorable prognosis compared to those over 1 year of age. However, there is little biological information about the age-related heterogeneity of neuroblastoma. We evaluated the biological profile comparing cases detected by mass screening with those detected clinically. A total of 238 patients with neuroblastoma were classified into four groups according to their age at diagnosis. Patients in group A were 0–5 months of age (n = 31). Patients in group B were detected clinically and were 6–11 months of age (n = 25). Patients in group C were 6–11 months of age and were detected by mass-screening (n = 97). Patients in group D were more than 12 months of age (n = 85). The age-related heterogeneity was evaluated by Kaplan-Meier survival analysis, several clinical markers (neuron specific enolase, ferritin, vanillylmandelic acid and homovanillic acid) at diagnosis, tumor Ha-ras p21 expression and tumor N-myc amplification. Infant neuroblastoma had unique features in comparison to neuroblastoma diagnosed over 12 months of age. Clinical outcome of the patients in groups A and C was quite favorable. Even patients with stage III or IV disease in group A had a favorable prognosis. However, stage IVs disease in group A was not necessarily associated with a good prognosis and the early death after diagnosis was also characteristic. The biological profile of tumors in group C was similar to that in group A but different from the profile in groups B and D. Tumors in group B had a biological profile intermediate between groups A and D. Cases detected by mass screening (group C) provided a new clinical entity with a good prognosis. The difference in biological profiles might affect their clinical outcome of respective age group. These analyses confirm the significance of prognostic markers and may help to direct an appropriate modality of treatment for the individual patient. 相似文献

Recently, the expression of vimentin has been reported in some carcinomas. This study was designed to clarify the significance of vimentin expression in solid type poorly differentiated adenocarcinomas of the stomach. Immunohistochemically, 239 poorly differentiated adenocarcinomas with solid components of the stomach were stained for vimentin. Vimentin-positive cases were also stained by CAM 5.2 using serial mirror sections. We found 15 (6.3%) vimentin-positive cases. Twelve of them demonstrated varying amounts of rhabdoid-like cells. Eight cases diffusely co-expressed vimentin and cytokeratin simultaneously. In addition, four co-expressing cases showed positive staining with Keratin-903 which recognizes the high molecular-weight cytokeratin. Most of the co-expressing cases showed a diffuse proliferation of polygonal tumour cells with focal cell-to-cell contact. The prognosis of the co-expressing cases was poor in comparison with that of the 89 vimentin-negative tumours ( P < 0.05). 相似文献

Nine Japanese cases of sarcoidosis in children of 4 years of age or younger have been reported in the literature, including the case presented here. Clinically, preschool sarcoidosis is distinctly different from that of older children; it is characterized by a triad of skin, joint and eye lesions without pulmonary involvement. It is easily confused with juvenile rheumatoid arthritis which also presents the symptoms of arthritis and uveitis. We report on a patient with preschool sarcoidosis who was initially diagnosed as having juvenile rheumatoid arthritis. We recommend prompt skin biopsy to differentiate between these conditions. 相似文献

OBJECTIVE: The standard protocol of antibiotic prophylaxis in radical prostatectomy remains to be established. We retrospectively compared the occurrence of perioperative infections following radical prostatectomy between two different protocols of antibiotic prophylaxis. METHODS: This study included 106 cases of radical retropubic prostatectomy managed on the clinical pathways. Two different protocols of antibiotic prophylaxis were used in otherwise identical pathways. Between January and December 2004, 50 patients received a second generation cephem, cefotiam, for 4 days, beginning 30 min before surgery (4-day group), whilst between December 2004 and July 2005, only two doses of cefotiam were given on the day of operation in 56 patients (1-day group). The incidence of surgical site infection (SSI) and remote infection (RI) was retrospectively investigated. RESULTS: Superficial incisional SSI occurred in one (1.8%) patient in the 1-day group, whereas no patient in the 4-day group developed SSI. No RI was observed in either the 1-day or 4-day group. Intravenous antibiotics were administered besides the pathway in a patient in the 1-day group because unexplained fever more than 38 degrees C continued postoperative day (POD) 2 through POD 4 without signs of SSI or RI. Excluding this case, postoperative more than 38 degrees C was rare and transient after POD 2. CONCLUSION: The incidence of SSI and RI was low and not significantly different between the 1-day and 4-day groups. Therefore, the 1-day protocol of prophylactic antibiotic treatment seems adequate for preventing perioperative infections in radical prostatectomy. 相似文献

Jak3 is a member of the Janus kinase family which plays an important role in cytokine signal transduction. Jak3 associates the γc chain of receptors for IL-2, IL-4, IL-7, IL-9 and IL-15, and is essential for the signal transduction of these cytokines. We have isolated Jak3 kinase from renal mesangial cells and demonstrated the constitutive expression of Jak3 in glomeruli in vivo. To investigate the physiological and pathological role of Jak3 in glomeruli, we prepared anti-Jak3 antibody and analysed the localization of Jak3 in glomeruli of renal biopsy samples from various nephritis patients and normal subjects. Among 61 nephritis patients and four normal subjects investigated in the present study, Jak3 was selectively localized to glomerular epithelia of IgA-N patients (14/34 cases) and focal glomerulosclerosis patients (1/5 cases), but not detected in minimal changes (n = 6), membranous glomerulonephropathy (n = 7), crescentic glomerulonephritis (n = 4), lupus nephritis patients (n = 5), and normal subjects (n = 4). The intense immunoreactivity for Jak3 is significantly associated with the decrease in creatinine clearance (81.5 ± 10.4 ml/min versus 104.3 ± 29.6 ml/min; P < 0.05, Student’s t-test) and the increase in level of serum creatinine (1.13 ± 0.33 mg/dl versus 0.75 ± 0.23 mg/dl; P < 0.01, Student’s t-test) in IgA-N patients. Furthermore, γc chain was concomitantly expressed with Jak3 in glomerular epithelia in vivo and in vitro, suggesting that signal transduction via γc-Jak3 cascade may be involved in the pathogenesis of glomerular injury of IgA-N. Taken together with the recent findings that IL-4-secreting T lymphocytes in affected glomeruli injure glomerular epithelium, the responsiveness of glomerular epithelium for IL-4 may be pathologically enhanced in IgA-N. 相似文献
