RESUMO

OBJECTIVES: This study aimed to evaluate the effects of royal jelly (RJ) supplementation on bone metabolism in postmenopausal women. METHODS: This was a randomized, double-blind, placebo-controlled clinical trial. Seventy-two healthy postmenopausal women aged 45-60 years within 5 years after menopause were randomized into two groups: women in the RJ group (n = 36) received capsules containing dried RJ (equivalent to 3000 mg of fresh RJ); and women in the placebo group (n = 36) received placebo daily for 6 months. Bone mineral density (BMD) of the lumbar spine (L2-L4) and left proximal femur, hip structural analysis (HSA) of the left hip, and bone turnover markers were measured. RESULTS: Although women in the placebo group experienced a significant loss of BMD and deterioration in HSA parameters of the femur, no significant differences were found in these parameters in women in the RJ group. The levels of total procollagen type 1 N-terminal propeptide (P1NP) and tartrate-resistant acid phosphatase decreased significantly in the placebo group; however, the total P1NP level, a marker of bone formation, was not significantly different in the RJ group at postintervention compared with baseline. CONCLUSION: RJ consumption may ameliorate decreases in femoral BMD and strength in postmenopausal women.

RESUMO

OBJECTIVE: Royal jelly (RJ) has been used for medical and nutritional purposes, and previous studies have indicated that it may have estrogenic activity. The present study investigated the effects of RJ on bone metabolism in ovariectomized (OVX) rats. METHODS: Rats (12 weeks old) were randomly divided into four groups, namely Baseline, Sham, OVX, and OVX + RJ groups. Rats in the Baseline group were killed immediately, whereas rats in the OVX and OVX + RJ groups underwent bilateral ovariectomy and those in the Sham group underwent sham operation. RJ was administered to rats in the OVX + RJ group daily for 12 weeks. At the end of the 12-week period, bone mass, bone histomorphometry, and bone mechanics were analyzed. RESULTS: Femur bone mineral density (BMD) was significantly lower in the OVX group than in the Sham group, and this decrease in BMD was not ameliorated by RJ administration. However, femur stiffness, as evaluated by a three-point bending test, was significantly higher in the OVX + RJ group than in the OVX group. CONCLUSION: The findings of the present study suggest that RJ does not prevent bone loss, but does improve bone strength in OVX rats.

RESUMO

OBJECTIVE: Royal jelly (RJ) from honeybees (Apis mellifera) has estrogenic activity. Estrogen deficiency after menopause leads to a high risk of memory impairment and depression as well as metabolic syndrome and osteoporosis. We here investigated the effect of RJ on memory impairment and depression-like behaviors in ovariectomized (OVX) rats. METHODS: OVX rats were administered with RJ for 82 days. Hippocampus-dependent spatial memory and depression-like behaviors were assessed by the Morris water maze test and the forced swimming test, respectively. The weights of body, brain and uterus and the contents of protein and myelin galactolipids including galactosylceramide and sulfatide were measured. RESULTS: Memory impairment and depression-like behaviors in OVX rats were recovered to the levels of sham-operated rats by RJ administration. Increased body weight and decreased uterine weight in OVX rats were recovered to the levels of sham-operated rats by 17ß-estradiol (E2) administration but not by RJ administration. In contrast, brain weight was slightly increased by RJ administration but not by E2 administration. The contents of protein and myelin galactolipids were higher in the brains of RJ-administered OVX rats than in the brains of E2-administered OVX rats. CONCLUSION: The results suggest that RJ has a beneficial effect on neurological symptoms of a menopausal disorder.

RESUMO

STUDY QUESTION: What are the frequency of, and the prognosis for, ovarian malignancies among patients who have undergone laparoscopic surgery for an adnexal mass? SUMMARY ANSWER: The rate of unexpected ovarian malignancy resected by laparoscopy was 1.5%, and the presence of an early-stage unexpected ovarian malignancy did not alter patient prognosis. WHAT IS KNOWN ALREADY: Even when laparoscopic surgery is used for the resection of an adnexal mass that is most likely benign, some patients are found to have malignant tumors post-operatively. STUDY DESIGN, SIZE, DURATION: The pathologic reports of 884 women who underwent laparoscopic resection of an adnexal mass between May 2007 and September 2013 at the Department of Obstetrics and Gynecology of Aichi Medical University Hospital, Nagakute, Japan, were reviewed retrospectively. PARTICIPANTS/MATERIALS, SETTING, METHODS: We conducted a systematic review of the medical records of patients diagnosed post-operatively with ovarian malignancies and abstracted their demographic, clinical and pathologic data. MAIN RESULTS AND THE ROLE OF CHANCE: A total of 1128 adnexal masses were resected, and 13 patients (1.5%) had ovarian malignancies: 6 ovarian cancer (1 mucinous, 1 endometrioid G1, 1 granulosa cell and 3 carcinoid) and 7 borderline tumors (BOTs; 5 mucinous and 2 serous). Of these, two patients with mucinous BOTs underwent fertility-sparing surgery and six patients underwent staging laparotomy. Due to cyst rupture during surgery, nine patients (69.2%) were upgraded to tumor stage IC. Secondary surgeries were performed in eight patients, with a mean interval of 88.9 days (range, 39-182 days) between the surgeries. All patients were alive and without evidence of disease at follow-up (mean follow-up, 38 months; range, 6-80 months). LIMITATIONS, REASONS FOR CAUTION: This was a retrospective study with a small case number and a short follow-up period. WIDER IMPLICATIONS OF THE FINDINGS: The presence of an early-stage unexpected ovarian malignancy did not alter the patient's prognosis, even if there was a significant delay in surgical staging after the finding of an unexpected malignancy during laparoscopy. STUDY FUNDING/COMPETING INTERESTS: No funding was obtained for this study and the authors report no conflicts of interest.

RESUMO

AIM: To evaluate radiation-induced myocardial damage after mediastinal radiotherapy using MRI. MATERIALS AND METHODS: Between May 2010 and April 2011, delayed contrast-enhanced MRI was performed for patients who had maintained a complete response to curative radiotherapy for oesophageal cancer for more than 6 months. The patients received radiotherapy with a median total dose of 66 Gy (60-70 Gy) for the primary tumour and metastatic lymph nodes. Images of MRI were analysed by a 17-segment method recommended by the American Heart Association. A segment included mainly in the 40 Gy dose line was defined as Segment 40 Gy, a segment included mainly in the 60 Gy dose line as Segment 60 Gy, and a segment out of the radiation fields as Segment OUT. The percentage of late gadolinium enhancement (LGE) was examined in those categories. The layer in which LGE was predominantly distributed was evaluated for each patient. RESULTS: Four hundred and eight segments in 24 patients were analysed. The median interval from completion of radiotherapy to MRI was 23.5 months (range 6-88 months). LGE was detected in 12 of the 24 patients. LGE was detected in 15.38% of Segment 40 Gy cases, 21.21% of Segment 60 Gy cases, and 0% of Segment OUT cases. LGE in mid-myocardial and subendocardial layers was detected in 11 patients and one patient, respectively. CONCLUSION: LGE suggesting radiation induced myocardial fibrosis was observed by performing delayed contrast-enhanced MRI. Care should be taken when planning radiotherapy to avoid late cardiac damage.

RESUMO

OBJECTIVE: Postmenopausal bone loss and the possible progression to osteoporosis are a major health concern. Mushrooms have been recognized as functional foods. Pleurotus eryngii extract has been reported to have estrogenic activity, suggesting that its consumption may mitigate postmenopausal bone loss. The aim of the present study was to determine the effect of supplementation with an ethanol extract of P. eryngii on bone metabolism in a postmenopausal osteoporosis rat model. METHODS: Female 12-week-old Wistar rats were subjected to either sham operation or bilateral ovariectomy. The ovariectomized rats were then subdivided into two groups: one fed the extract and the other not. Twelve weeks after surgery, indices of bone mass, bone histomorphometry, and bone mechanics were measured. RESULTS: The right femur bone mineral content and density of the ovariectomized group were significantly lower than in the Sham group, and extract supplementation did not have any significant effect on these differences. Furthermore, ovariectomy significantly increased measures of mineralizing surface and bone formation rates; again, extract supplementation again had no significant effect. CONCLUSION: Our findings suggest that the ethanol extract of P. eryngii does not alter bone metabolism in ovariectomized rats, suggesting that consumption of P. eryngii may not be beneficial in slowing bone loss after menopause.

RESUMO

The purpose of the present study was to evaluate long-term results of chemoradiotherapy for clinical T1b-2N0M0 esophageal cancer and to compare outcomes for operable and inoperable patients. Patients with stage I esophageal cancer (Union for International Cancer Control [UICC] 2009), excluding patients with cT1a esophageal cancer, were studied. All patients had histologically proven squamous cell carcinoma. Operable patients received cisplatin and 5-fluorouracil with concurrent radiotherapy of 60 Gy including a 2-week break. Inoperable patients received nedaplatin and 5-fluorouracil with concurrent radiotherapy of 60-70 Gy without a pause. End-points were overall survival rate (OS), cause-specific survival rate (CSS), progression-free survival rate (PFS), and locoregional control rate (LC). Thirty-seven operable patients and 30 medically inoperable patients were enrolled. There was a significant difference in only age between the operable group and inoperable group (P = 0.04). The median observation period was 67.9 months. In all patients, 5-year OS, CSS, PFS, and LC were 77.9%, 91.5%, 66.9%, and 80.8%, respectively. Comparison of the operable group and inoperable group showed that there was a significant difference in OS (5-year, 85.5% vs. 68.7%, P = 0.04), but there was no difference in CSS, PFS, or LC. Grade 3 or more late toxicity according to Common Terminology Criteria for Adverse Events v 3.0 was found in seven patients. Even in medically inoperable patients with stage I esophageal cancer, LC of more than 80% can be achieved with chemoradiotherapy. However, OS in medically inoperable patients is significantly worse than that in operable patients.

RESUMO

BACKGROUND: Metastasis to a trocar tract (port-site metastasis, PSM) is an uncommon but serious complication that possibly compromises the prognosis of cancer patients treated laparoscopically. CASE: A 42-year-old Japanese woman had a 20-cm benign right ovarian cyst resected using gasless lift-laparoscopy. Five years and eight months postoperatively, she noticed a three-cm subcutaneous tumor involving the trocar tract. She was also found to have a pelvic mass and an exploratory laparotomy revealed left ovarian cancer. Based on the histopathological findings, the subcutaneous tumor was diagnosed as a metastasis from the ovarian cancer. CONCLUSIONS: This case suggested that PSM could occur without direct or indirect wound contamination during laparoscopic surgery.

RESUMO

Uterine cervical prolapse is extremely rare during pregnancy and may predispose patients to serious complications, including maternal death. Four patients are presented here: two patients had pre-existing prolapse and the other two developed prolapse during pregnancy. All the patients required hospitalisation due to threatened pre-term labour. Two patients were delivered via caesarean section at term due to obstetrical complications, but the others delivered spontaneously. In a case of uterine cervical prolapse lasting until term, hospitalisation with bed rest, anti-tocolytic agents and genital hygiene may protect the cervix, resulting in favourable maternal and fetal prognoses.

RESUMO

BACKGROUND: Acute generalized exanthematous pustulosis (AGEP) is an uncommon adverse cutaneous reaction, most commonly associated with drugs. CASE: A 38-year-old primigravida whose labor had been induced developed erythema over her chest and abdomen. She was transferred to our department after a failed vacuum extraction, and delivered a mature infant by forceps. On day three postpartum she developed a 40.4 degrees C fever. Although ceftriaxone was administered, her fever persisted (>38 degreesC). On day six of the puerperium, diffuse non-follicular pustules appeared over her neck and trunk, and AGEP was suspected. Two days after ceftriaxone was withdrawn, the eruptions started to resolve without any medical intervention. CONCLUSION: Once the diagnosis of AGEP has been made, the antibiotics being administered must be discontinued. If continued treatment is required, pharmacologically distinct antibiotics must be used instead to aid the rapid self-limitation of the disease.

RESUMO

BACKGROUND: Metastasis to the uterine cervix from non-gynecologic neoplasms is rare. However, metastatic tumors sometimes precede the diagnosis of a primary tumor, and may lead to diagnosis of the primary tumor. CASE: A 50-year-old woman was referred to us complaining of increasing right flank pain. Computed tomography scan demonstrated an enlarged uterus with right-sided hydronephrosis and hydroureter. Cervical cytology revealed adenocarcinoma. She was considered to have a Stage IIIB cervical adenocarcinoma. Although no cervical lesion was seen colposcopically, histopathology from biopsies of the uterine cervix revealed poorly differentiated adenocarcinoma infiltrating around the normal endocervical glands. A metastasis from the gastrointestinal tract was suspected. The patient underwent gastroscopy and was found to have Borrmann type IV gastric cancer. Biopsies confirmed a poorly differentiated adenocarcinoma with signet ring cells. CONCLUSION: Physicians should bear in mind that metastatic tumors may precede the diagnosis of a primary tumor and could manifest by mimicking advanced cervical cancer.

RESUMO

OBJECTIVE: Fahr disease (FD) is a rare neurological and psychiatric disorder. The disease is classified by intracranial calcification of the basal ganglia with the globus pallidus region being particularly affected. We examined a young woman with visual hallucinations, delusions of persecution and a history of performing arson with possible third-generation FD. METHOD: Case report of third-generation FD. RESULTS: A 23-year-old woman was arrested for two arsons: i) The patient exhibited progressive psychotic symptoms, including visual hallucinations, delusion of injury, irritability, lability of mood, mental retardation and visual disorders and ii) Computed tomography (CT) imaging demonstrated bilateral calcifications of the basal ganglia (globus pallidus) in the patient, her mother and her grandmother. CONCLUSION: We found a family with a three-generation history of FD who exhibited calcification in the brain and mental retardation. Compared to her mother, the patient described here displayed anticipation of disease onset.

RESUMO

BACKGROUND: Toxic shock syndrome caused by group A streptococci (GAS) is rare around the time of delivery, but it may predispose pregnant women to a life-threatening condition. CASE: A 32-year-old primigravida at 21 weeks of gestation was taken to our hospital with acute severe abdominal pain following fever. On admission the fetus was found to be dead, and intrauterine fetal demise due to placental abruption was suspected. An emergency cesarean section found no sign of placental abruption. Soon after the surgery, the patient went into shock but was successfully treated with intensive care. Although repeated blood cultures failed to detect microorganisms, the patient was positive for streptococcal pyrogenic toxin A, which is a superantigen of GAS. CONCLUSION: Once GAS infection is suspected, regardless of negative blood cultures, supportive care in the intensive care unit is mandatory.

RESUMO

A 75-year-old female patient underwent distal gastrectomy with lymph node dissection for gastric cancer. Six months later, computed tomography (CT) and magnetic resonance imaging (MRI) revealed liver metastasis and radio frequency ablation (RFA) was performed. Ten months later, she underwent a partial hepatectomy for recurrent hepatic metastasis. Then, pulmonary nodules were revealed 1 year later, and segmentectomy (S4 + S5) for left pulmonary metastasis and wedge resection for right middle lobe pulmonary metastasis were sequentially performed after 9 months and 10 months observation by CT, respectively. Two years have passed since the last surgery, and the patient has survived more than 5 years since initial gastrectomy.

RESUMO

Cholinergic stimulation of the lateral hypothalamic neurons with intrahypothalamic microinjections of acetylcholine or carbachol caused a marked increase in the content of the active form of glycogen (starch) synthase in the liver. Total activity of the enzyme (active plus inactive forms) was not increased significantly. The lowest effective dose of acetylcholine was 5 X 10(-10) mole, and the optimum dose was 5 X 10(-9) mole. Similar applications of other neurotransmitters, such as norepinephrine, dopamine, serotonin, and gamma-aminobutyric acid, did not affect the enzyme's activity.

RESUMO

BACKGROUND AND STUDY AIMS: Endoscopic submucosal dissection (ESD) is one of the most complex and lengthy endoscopic procedures, so deep sedation during ESD is indispensable. Our study aims were to determine whether bispectral index (BIS) monitoring is useful in titrating and reducing the dose of the sedative propofol during ESD, and to measure the satisfaction of patients and endoscopists involved in this complex and lengthy endoscopic therapy. PATIENTS AND METHODS: We performed a prospective, randomized clinical trial from July 2006 to February 2008. A total of 156 patients, with gastric neoplasm to be treated using ESD, were randomized to two groups. The BIS group (n = 78) was monitored for propofol sedation using BIS, and the no-BIS group (n = 78) was monitored by standard methods only. The two groups were compared by evaluating the doses of propofol administered to patients and the satisfaction scores (scale of 0 - 10) of patients and endoscopists. RESULTS: Although there were no significant differences between the two groups in the mean dose of propofol used (BIS group vs. no-BIS group, 5.32 mg/kg/hour vs. 4.85 mg/kg/hour; P = 0.10), the satisfaction scores of the patients (9.15 vs. 7.94; P < 0.01) and endoscopists (8.53 vs. 6.42; P < 0.001) were significantly higher with BIS monitoring. CONCLUSIONS: Monitoring with BIS during the ESD procedure did not lead to a reduction in the dose of propofol required, but did lead to higher satisfaction scores from the patients and endoscopists. A complicated and prolonged endoscopic treatment such as ESD can be carried out with optimal safety, control, and comfort by using BIS to monitor propofol sedation.

RESUMO

Connective tissue growth factor (CTGF/CCN2) can be induced by various forms of stress such as exposure to high glucose, mechanical load, or hypoxia. Here, we investigated the molecular mechanism involved in the induction of ctgf/ccn2 by hypoxia in a human chondrosarcoma cell line, HCS-2/8. Hypoxia increased the ctgf/ccn2 mRNA level by altering the 3'-untranslated region (UTR)-mediated mRNA stability without requiring de novo protein synthesis. After a series of extensive analyses, we eventually found that the cis-repressive element of 84 bases within the 3'-UTR specifically bound to a cytoplasmic/nuclear protein. By conducting a UV crosslinking assay, we found the cytoplasmic/nuclear protein to be a 35 kDa molecule that bound to the cis-element in a hypoxia-inducible manner. These results suggest that a cis-element in the 3'-UTR of ctgf/ccn2 mRNA and trans-factor counterpart(s) play an important role in the post-transcriptional regulation by determining the stability of ctgf/ccn2 mRNA.
