6%; FEV1, 14.4%). RFS was comparable between patients who underwent lobectomy and segmentectomy in both the unmatched (73.4% and 82.7%, respectively; P = .30) and the 37 propensity-matched (79.5% and 80.1%, respectively) patients. Similarly, OS was comparable between patients who underwent lobectomy and segmentectomy in the unmatched (80.0% and 90.6%, respectively; P = .42) and matched (82.9% and 89.3%, respectively) patients. Conclusions Segmentectomy can be feasible in patients with radiologically solid-dominant clinical stage IA lung cancers measuring 2.1 to 3 cm when patients are appropriately selected.Background To explore the potential advantage of preoperative anti-angiogenosis therapy, we implemented a study to evaluate the efficacy of recombinant human endostatin (EN) in combination with neoadjuvant chemotherapy in the treatment of stage III breast cancer. Patients and methods Eighty-seven patients were randomized to neoadjuvant TEC (docetaxel, epirubicin, and cyclophosphamide) or to EN+TEC, followed by surgery. The primary endpoint was the objective response rate (ORR). Secondary endpoints included pathologic complete response (pCR), relapse-free survival (RFS), overall survival (OS), and safety. Results Patients receiving EN+TEC achieved significantly higher ORR (81.82%; 36/44) compared with those receiving TEC (58.14%; 25/43; P=0.016). There was a non-significant trend of increased pCR with EN treatment (15.91% vs. 6.98%). The median follow-up was 54 months and revealed a significantly higher RFS with EN+TEC (median, 67.3 months; 95% confidence interval [CI], 61.0-73.7 months), compared with TEC (median, 55.0 months; 95% CI, 48.3-61.7 months; P =0.014). EN+TEC also significantly improved OS (74.2 months; 95% CI, 68.9-79.6 months), compared with TEC (59.1 months; 95% CI, 52.0-66.1 months; P =0 .006). The 3- and 5-year OS rates are estimated to be 88.5% and 82.8% with EN+TEC and 76.7% and 54.4% with TEC, respectively. Cox proportional regression analyses showed that EN+TEC was associated with improved OS (hazard ratio, 0.377; 95% CI, 0.418-0.959; P =0 .041). There was no significant difference in adverse events between EN+TEC and TEC. Conclusion The combination of EN+TEC neoadjuvant chemotherapy significantly improved the ORR and OS, suggesting a benefit of adding anti-angiogenesis to standard chemotherapy in the treatment of locally advanced breast cancer.Optimal resection of the involved portion of the thyroid gland is decisive in long term functional and oncologic results of a Laryngectomy. Regardless of the setting and techniques adopted in performing the laryngeal surgery, we propose a concept of adequate removal of the infiltrated thyroid glandular tissue based on the current status of available literature and our own published experience of managing the thyroid gland in laryngectomies.The lowest recorded core temperature from which a person with accidental hypothermia has survived neurologically intact is 11.8°C in a 2-y-old boy. The lowest recorded temperature from which an adult has been resuscitated neurologically intact is 13.7°C in a 29-y-old woman. The lowest core temperature with survival from induced hypothermia has been quoted as 9°C. We discovered a case series (n=50) from 1961 in which 5 patients with core temperatures below 11.8°C survived neurologically intact. The lowest core temperature in this group was 4.2°C. The authors also presented cardiovascular and other physiologic data at various core temperatures. The patients in the case series showed a wide variation in individual physiological responses to hypothermia. It is not known whether survival from accidental hypothermia is possible with a core temperature below 11.8°C, but this case series suggests that the lower limit for successful resuscitation may be far lower. We advise against using core temperature alone to decide whether a hypothermic patient in cardiac arrest has a chance of survival.Introduction Cold-induced vasodilation (CIVD) is seen in the extremities during exposure to cold. A strong vasodilation response has been associated with a decreased risk of cold injury. Increasing CIVD might further decrease this risk. The calcium-channel blocker nifedipine causes vasodilation and is used to treat Raynaud's syndrome and chilblains. Nifedipine is also used for high altitude pulmonary edema and could potentially serve a dual purpose in preventing frostbite. The effects of nifedipine on CIVD have not been studied. Methods A double-blind crossover study comparing nifedipine (30 mg SR (sustained release) orally twice daily) to placebo was designed using 2 sessions of 4 finger immersion in 5°C water, with 24 h of medication pretreatment before each session. Finger temperatures were measured via nailbed thermocouples. The primary outcome was mean finger temperature; secondary outcomes were mean apex and nadir temperatures, first apex and nadir temperatures, subjective pain ranking, and time of vasodilation onset (all presented as mean±SD). Results Twelve volunteers (age 29±3 [24-34] y) completed the study. No significant difference in finger temperature (9.2±1.1°C nifedipine vs 9.0±0.7°C placebo, P=0.38) or any secondary outcome was found. Pain levels were similar (2.8±1.6 nifedipine vs 3.0±1.5 placebo, P=0.32). The most common adverse event was headache (32% of nifedipine trials vs 8% placebo). Conclusions Pretreatment with 30 mg of oral nifedipine twice daily does not affect the CIVD response in healthy individuals under cold stress.Lactose intolerance is a condition with an elevated prevalence worldwide, especially in Latin American, Asian, and African countries. read more The aim of the present narrative review was to highlight the importance of accurately diagnosing lactose intolerance to prevent self-diagnosis that results in the unnecessary elimination of milk and dairy products from the diet and the consequent deprivation of nutrients that could be essential at certain stages of life. The pathophysiologic mechanism of deficient lactose absorption in the intestine can be primary, secondary to other enteropathies, or coexistent with other intestinal diseases with similar symptoms, such as irritable bowel syndrome, bacterial overgrowth syndrome, or celiac disease, causing confusion in relation to diagnosis and treatment. Lactose intolerance consists of a set of symptoms attributed to the consumption of milk and dairy products that are assumed to be due to deficient digestion of that disaccharide. A wide range of tests have been validated to detect deficient digestion that include blood tests, genetic mutation analyses, breath tests, and recently, a urine test, all of which are described in the present article.
