Metabolic syndrome: a common problem among office workers.

BACKGROUND: Metabolic syndrome (MSx) is associated with several health problems. Workers are an important part of any organization. OBJECTIVE: To determine the prevalence of MSx and related variables among office workers. METHODS: This cross-sectional study evaluated 1488 office workers in Qom province, Central Iran, by using a multi-stage cluster sampling. Diagnosis of MSx was based on blood HDL-cholesterol, triglyceride, and fasting blood sugar (FBS) levels and waist circumference, and blood pressure. RESULTS: The overall prevalence of MSx was 35.9% (95% CI 33.5% to 38.3%), higher in men (37.2%) than in women (20.6%), and increased with age. The most common laboratory findings of MSx were hypertriglyceridemia (45.9%) and low HDL-cholesterol level (45.5%). Office workers with MSx had a significantly (p<0.001) higher body mass index than those without MSx. Lack of regular leisure time physical activity (p=0.003), and low intake of fruits (p=0.02) were associated with MSx. CONCLUSION: The prevalence of MSx was very high among office workers. Workplace health improvement programs through identifying and preventing MSx are necessary for improvement of staff's health.

Optimal dose of pre-incision/post-incision gabapentin for pain relief following lumbar laminectomy: a randomized study.

BACKGROUND: Gabapentin has been introduced as an effective agent for post-operative pain control. This study aimed to test the effects of pre- and post-incision administration of different doses of gabapentin on post-operative morphine requirement and pain following lumbar laminectomy. METHODS: In this randomized clinical trial, 175 patients were allocated into seven groups of 25 patients each to receive placebo or gabapentin 600, 900 or 1200 mg pre- or post-incision. Total patient-controlled intravenous morphine consumption during the first 24 post-operative hours, and the time to the first demand for morphine were recorded. Pain score at rest (visual analogue scale) was recorded every 30 min in the first 4 h and then every 2 h until 24 h post-operatively. Side-effects were observed. RESULTS: In the first 12 h, morphine consumption was less, pain scores were lower and the time to the first demand for analgesia was longer in groups receiving gabapentin 900 or 1200 mg either pre- or post-incision, compared with placebo and gabapentin 600 mg (P<0.001). There was no difference between gabapentin 900 and 1200 mg. Pain score, morphine consumption and time to the first demand for analgesia in equal pre- or post-incision doses of gabapentin were not significantly different. No differences in the side-effects were observed between groups. CONCLUSION: Gabapentin 900 or 1200 mg, administered either pre- or post-incision, was found to be effective in pain management following lumbar laminectomy. Similar doses of gabapentin provide the same post-operative analgesia whether administered pre- or post-incision.

The effects of prostaglandin E1 on interleukin-6, pulmonary function and postoperative recovery in oesophagectomised patients.

The inflammatory reactions and tissue response after oesophagectomy are leading causes of postoperative morbidity and mortality. We evaluated the effects of intraoperative infusion of prostaglandin E1 (PGE1) on interleukin-6 (IL-6) levels, (A-a) DO2, pulmonary function and complications. This randomised double-blind clinical trial study was performed on patients undergoing transthoracic oesophagectomy due to cancer Thirty patients were randomly allocated to two groups: the PGE1 group (infusion of PGE1 20 ng kg(-1) min(-1)) and a placebo group (infusion of normal saline 0.9%). The infusion was started before induction of anaesthesia and continued until the end of the operation. The groups were comparable in basic characteristics and preoperative pulmonary function. Patients in the PGE1 group were discharged significantly earlier from the intensive care unit (72+/-9 vs 83+/-17 hours) and hospital (13+/-4 vs 18+/-8 days) (P=0.04 and 0.03, respectively). The (A-a) DO2 was significantly less in the PGE1 group at 12 and 24 hours after the operation (P=0.001, P=0.003, respectively). Postoperatively, IL-6 levels were significantly higher in the placebo group than in the PGE1 group. There were no differences in the forced expiratory volume in the first second or forced vital capacity. The findings indicate that infusion of PGE1 attenuates the increase in serum levels of IL-6 in patients undergoing esophagectomy and improves the (A-a) DO2. Stays in the intensive care unit and hospital were shorter in the PGE1 group. However, there were no differences in pulmonary complications.

Laparoscopic splenectomy for isolated parenchymal splenic metastasis of ovarian cancer.

Metastatic carcinoma of the spleen occurs in a setting of widespread malignant disease. Solitary parenchymal splenic metastasis of ovarian carcinoma is rare. We report a case of a 59-year-old woman who presented with an elevated serum CA125 level due to a solitary splenic metastasis after a long disease-free period. She was treated with laparoscopic splenectomy followed by chemotherapy. The literature contains 16 cases of solitary parenchymal splenic metastasis of ovarian carcinoma. Our case is the third case that was treated with laparoscopic splenectomy. We review the literature, and we focus on the laparoscopic approach in managing these cases.

Primary pure squamous cell carcinoma of the breast: a case report and review of the literature.

Pure primary squamous cell carcinoma (SCC) of the breast is a rare condition. The exact histogenesis of this malignancy is unclear. The rarity of the condition makes it difficult to draw firm conclusions on the course of the disease and the overall prognosis. We report a case of pure primary SCC of the breast occurring in a 62-year-old woman and presenting as an enlarged breast lesion with bleeding. We also review the literature for all cases of pure primary SCC.
