ABSTRACT
Purpose@#This study was performed to investigate the efficacy and safety of short-course radiation therapy (SCRT) and sequential chemotherapy followed by delayed surgery in locally advancer rectal cancer with subgroup analysis between the older and young patients. @*Materials and Methods@#In this single-arm phase II clinical trial, eligible patients with locally advanced rectal cancer (T3–4 and/or N1–2) were enrolled. All the patients received a median three sequential cycles of neoadjuvant CAPEOX (capecitabine + oxaliplatin) chemotherapy. A total dose of 25 Gy in five fractions during 1 week was prescribed to the gross tumor and regional lymph nodes. Surgery was performed about 8 weeks following radiotherapy. Pathologic complete response rate (pCR) and grade 3–4 toxicity were compared between older patients (≥65 years) and younger patients (<65 years). @*Results@#Ninety-six patients with locally advanced rectal cancer were enrolled. There were 32 older patients and 64 younger patients. Overall pCR was 20.8% for all the patients. Older patients achieved similar pCR rate (18.7% vs. 21.8; p = 0.795) compared to younger patients. There was no statistically significance in terms of the tumor and the node downstaging or treatment-related toxicity between older patients and younger ones; however, the rate of sphincter-saving surgery was significantly more frequent in younger patients (73% vs. 53%; p=0.047) compared to older ones. All treatment-related toxicities were manageable and tolerable among older patients. @*Conclusion@#Neoadjuvant SCRT and sequential chemotherapy followed by delayed surgery was safe and effective in older patients compared to young patients with locally advanced rectal cancer.
ABSTRACT
Fecal incontinence is a challenging condition in that it exerts various psychosocial impacts on daily life. Different treatment modalities have been suggested for fecal incontinence. The present study aimed to evaluate the efficacy of biofeedback therapy in combination with surgery in the management of fecal incontinence. The present randomized controlled trial was performed on 27 women with a complaint of fecal incontinence because of delivery trauma. The patients underwent sphincteroplasty and levatorplasty via the same method by 2 colorectal surgeons. In Group I, biofeedback therapy was performed 3 months before and 6 months after the surgery; in Group II, biofeedback therapy was applied only 6 months after the surgery; and in Group III, only surgical management was performed. The results revealed a significant difference between the preoperative and postoperative Wexner scores of incontinence in all the 3 groups. Additionally, the difference between the preoperative and postoperative scores was significant only in Group I and Group III, but not in Group II. The reduction in the Wexner score was significantly less in Group III. However, no significant difference was observed between the 3 groups concerning the mean difference of preoperative and postoperative manometry. The present study revealed no significant role for biofeedback therapy alone in the improvement of manometric evaluation. However, the Wexner score, which is an indicator of patient satisfaction, increased with biofeedback therapy following sphincteroplasty. In general, surgical treatment is now reserved for selected patients with fecal incontinence and has recently been developed with biofeedback therapy
ABSTRACT
Hypoglycemia is a well-known paraneoplastic manifestation of hepatocellular carcinoma usually occurring in the terminal stages of the disease. However, during initial presentation this manifestation is uncommon. We report a 77-year-old man who presented with signs and symptoms of severe hypoglycemia [for example drowsiness]. After clinical work-ups, we detected a large mass in the liver. Interestingly, after surgical excision of the tumor, the attacks of decreased level of consciousness and hypoglycemia seized

In this study, we have developed an electrotherapy device in order to improve the outcome and decrease the number of referrals and duration of treatment of internal hemorrhoid. We treated 2015 hemorrhoids among 931 patients [382 males and 549 females]; 319 hemorrhoids were grade 1, 1158 grade 2 and 538 grade 3, from May 1995 to October 2002, at Nemazee and Faghihee Hospitals in Shiraz University of Medical Sciences, Shiraz, Iran. All patients were referred due to fresh rectal bleeding or reducible prolapsed hemorrhoid with no response to medical treatment. After introduction of anesthesia, 27-30 mAmp direct current was applied to each hemorrhoid with durations of 4.5 minutes for grade 1, 5.5 minutes for grade 2 and 7 minutes for grade 3. Our results showed that 97.1% of patients responded well to the treatment and 27 patients returned with fresh rectal bleeding or prolapsed hemorrhoid in 2 weeks to 2 months postoperatively. Ninety-six% of the patients were discharged on the same operating day. After 24 hours postoperation, 92% of the patients had no any pain and no need any analgesic. Among those patients who had not responded to the treatment; 24 cases underwent electrotherapy for a 2nd time and 3 patients were treated excising their prolapsed hemorrhoids. No other complications were detected. Postoperative pain was mild and tolerable and 93.2% of patients returned to normal activity after 2 days. Electrotherapy with the above mentioned method is considered safe and effective without any major complications and with acceptable patient's satisfaction. This method can be used for treatment of grades 1, 2 and 3 hemorrhoids
