DERMATOLOGIC SURGERY, Issue 7 2000
Dania Tannir MD
Background. Reconstruction of the entire ear lobule is challenging and complex. We present a case in which a banner transposition flap from the preauricular and mandibular area of the cheek resulted in an excellent cosmetic outcome. Objective. To demonstrate the utility of a bilayered banner transposition flap to reconstruct a full-thickness defect of the inferior one-third of the pinna. Methods., The technique employed in this reconstruction is described and previously reported techniques are reviewed. Results., A symmetrical earlobe with normal tissue consistency was created, as noted at 4 months postoperatively. Conclusion. Utilization of a banner transposition flap should be considered as an excellent method for reconstruction of full-thickness defects of the lower one-third of the ear. [source]


Squamous cell carcinoma arising from a congenital duplication cyst of the esophagus in a young adult

DISEASES OF THE ESOPHAGUS, Issue 3-4 2001
S. Singh
Squamous cell carcinomas arising from the congenital anomalies in the esophagus are rare. One such case of an 18-year-old man, with an associated history of ventricular septal defect, who developed an epithelial malignancy within the duplication cyst extending to involve the lower third of esophagus is presented here. He responded well to radical treatment using concurrent chemo-irradiation, and continues to be free of disease after a follow-up of 14 months. [source]


Hippocampus modulates the behaviorally-sensitizing effects of nicotine in a rat model of novelty-seeking: Potential role for mossy fibers

HIPPOCAMPUS, Issue 10 2007
Amrinder S. Bhatti
Abstract Present experiments investigate interactions between a rat model of the novelty-seeking phenotype and psychomotor sensitization to nicotine (NIC) in adolescence, and the potential role of hippocampal mossy fibers in mediating the behaviorally-sensitizing effects of NIC. Outbred rats were phenotype-screened as high-responders (HR; locomotor reactivity to novelty score ranking in the upper third of the population) or low-responders (LR; locomotor reactivity to novelty score ranking in the lower third of the population). In Experiment 1, both phenotypes were trained with four NIC injections (at 3-d intervals on postnatal days 33,44), and lidocaine microinfusion was used to temporarily inactivate the hippocampal hilus at each NIC injection. Systemic saline and microinjection of artificial cerebral spinal fluid (CSF) were used as controls. During NIC training, lidocaine inactivation caused augmented locomotor response to NIC in HRs compared to LRs irrespective of injection days. Following 1 week of abstinence, all animals were challenged with a low dose of NIC. During challenge, previously NIC/CSF trained LRs and HRs were divided into two; one half receiving lidocaine inactivation of the hippocampal hilus and the other half receiving CSF control microinjection. Only HRs showed behavioral sensitization to the challenge dose of NIC, which was enhanced with lidocaine inactivation. In Experiment 2, a single NIC exposure was found sufficient to induce sensitization to the challenge dose of NIC in HRs, and concurrently an enlarged supra-pyramidal mossy fiber (SP-MF) terminal field. The increase in the SP-MF volume in HRs was greater with repeated NIC training. In both single and repeated NIC training cases, a significant positive morphobehavioral correlation was observed between challenge NIC-induced locomotion and the SP-MF terminal field volume. These findings suggest that the HR hippocampal mossy fibers are vulnerable to neuroadaptive alterations induced by NIC, which may be a substrate for the observed behavioral vulnerability to NIC. © 2007 Wiley-Liss, Inc.

Randomised comparison of the FerX Ella antireflux stent and the ultraflex stent: Proton pump inhibitor combination for prevention of post-stent reflux in patients with esophageal carcinoma involving the esophago-gastric junction

JOURNAL OF GASTROENTEROLOGY AND HEPATOLOGY, Issue 5 2008
Tarun Sabharwal
Abstract Background and Aim:, Metal stents placed across the gastroesophageal junction in patients with malignant dysphagia frequently present with reflux symptoms. We compared an antireflux stent with a standard open stent used in combination with proton pump inhibitor medication. Methods:, Forty-nine patients with dysphagia due to inoperable carcinoma in the lower third of the esophagus were randomly selected to receive either a antireflux valve stent (FerX-Ella) (n = 22) or a covered standard open stent (Ultraflex), which was combined with proton pump inhibitors such as omeprazole (n = 26). The technical success, the presence of reflux, and complications were recorded. Results:, Reflux was seen in 3/22 patients (13.6%) in the FerX-Ella group and in 2/26 patients (7.7%) in the Ultraflex and proton pump inhibitor combination group (P -value not significant). In both groups, a significant improvement in the dysphagia score was seen and no statistically significant difference was detected between the two groups (P = 0.84). The FerX-Ella stents migrated more frequently (32%) than the Ultraflex stents (23%). This also necessitated surgical intervention more frequently in the FerX-Ella group (2/22, 9.1%) compared to the Ultraflex group (1/26, 3.8%). Conclusion:, The antireflux stent had no demonstrable advantages compared to the combination of standard open stent and proton pump inhibitor medication. [source]


Reality of the G-spot and its relation to female circumcision and vaginal surgery

JOURNAL OF OBSTETRICS AND GYNAECOLOGY RESEARCH (ELECTRONIC), Issue 5 2009
Saeed Mohamad Ahmad Thabet
Abstract Aim:, To clarify the reality of the G-spot anatomically, functionally and histologically, and to determine the possible effect of female circumcision and anterior vaginal wall surgery on the integrity and function of the G-spot. Methods:, A controlled descriptive and comparative cohort prospective study was conducted at Kasr El Aini School of Medicine, Cairo University, Cairo, Egypt, of 50 uncircumcised and 125 circumcised women with small to moderate anterior vaginal wall descent. Preoperative sexual examination was performed to map the site of the G-spot and other anatomical landmarks on the anterior vaginal wa11 and to verify the associated circumcision state. Pre- and postoperative sexual assessment and histological examination of different mapped sites in the anterior vagina were also conducted. Results:, Histological findings, results of the anatomical and sexual mapping of the anterior vaginal wall and sexual scores were recorded. The G-spot was proved functionally in 144 (82.3%) of women and anatomically in 95 (65.9%). The latter appeared as two small flaccid balloon-like masses on either side of the lower third of the urethra and were named ,the sexual bodies of the G-spot'. These bodies were significantly detected in all histo-positive cases in the circumcised women and in the uncircumcised women who had small or average clitorises. The G-spot was also proved histologically in 47.4% of all cases and was formed of epithelial, glandular and erectile tissue. Sex scores were significantly higher in the histo-positive cases with sexual bodies but significantly dropped after anterior vaginal wall surgery. In contrast, female circumcision rarely alters the scores. Conclusion:, The G-spot is functional reality in 82.3% of women, an anatomical reality in 54.3% and a histological reality in 47.4%. Anterior vaginal wall surgery usually affects the G-spot and female sexuality, but female circumcision rarely affects them. [source]


Apoptosis, anoikis and their relevance to the pathobiology of colon cancer

PATHOLOGY INTERNATIONAL, Issue 4 2000
Minalini Shanmugathasan
The maintenance of a constant number of cells in an adult organism is a tightly regulated process. This is particularly important in organs where cells are in a constant rate of renewal during the entire lifespan. In these organs, cell number homeostasis is the direct consequence of a bal-ance between cell proliferation and apoptosis. The colonic epithelium is an example of such a site and the high prevalence of colon cancer makes the understanding of cell number homeostasis more important to define. Normal colonic epithelium is organized in crypts where cell proliferation, migration, differentiation and apoptosis are topographically organized in a linear fashion along the crypt axis. Normal colonic crypts are composed of stem cells at the base, a proliferation and a differentiation zone in the lower third of the crypt, a migration zone in the upper two-thirds, and the surface epithelium where senescent cells are eliminated by apoptosis. Globally, apoptosis can be defined as a normal process of cell suicide, critical for development and tissue homeostasis. Colonic epithelial cells migrate from the base of the crypt to the surface epithelium in 6,7 days. The normal architecture of the crypt is maintained by a balance between cell proliferation at the base and apoptosis at the top of the crypt and surface epithelium. [source]


Oesophagectomy for tumours and dysplasia of the oesophagus and gastro-oesophageal junction

ANZ JOURNAL OF SURGERY, Issue 4 2009
Krishna Epari
Abstract Background:, Neoadjuvant therapy, radical lymphadenectomy and treatment in high-volume centres have been proposed to improve outcomes for resectable oesophageal tumours. The aim of the present study was to review the oesophagectomy experience of a single surgeon with a moderate caseload who uses neoadjuvant therapy selectively and performs a conservative lymphadenectomy. Methods:, A retrospective review of prospectively collected data was performed. The study included 125 consecutive attempted oesophageal resections performed by a single surgeon (RC) from 1993 to 2006. Results:, All patients were staged with computed tomography and also laparoscopy for lower third and junctional tumours. Endoscopic ultrasound was used in 69%. Seventy-seven per cent were adenocarcinomas. Neoadjuvant therapy was used selectively in 23%. One hundred and twenty-one resections were carried out, giving an overall resection rate of 97% with an R0 resection in 82%. In-hospital mortality was 0.8%, clinical anastomotic leak 1.7% and median length of stay 14 days. Overall median and 5-year survival were 46 months and 47%. Stage-specific 5-year survival was 100%, 71%, 41% and 21% for stages 0, I, II and III, respectively. Isolated local recurrence occurred in 8%. Conclusions:, A moderate volume surgeon with specialist training in oesophageal resectional surgery can achieve a low mortality and anastomotic leak rate with good survival outcomes. The role for neoadjuvant therapy and radical lymphadenectomy is controversial and remains to be clearly defined. Accurate preoperative staging is essential for selection of patients for curative surgery with or without neoadjuvant therapy and for comparison of results. [source]


Epidemiological study of oesophageal and gastric cancer in south-east England,

BRITISH JOURNAL OF SURGERY (NOW INCLUDES EUROPEAN JOURNAL OF SURGERY), Issue 9 2001
Mr H. M. Kocher
Background: This epidemiological study was carried out to establish the magnitude of the changing incidence of gastric and oesophageal cancer. Methods: Time-trend analyses of subsite-specific cancers of the oesophagus and stomach were performed using data from the Thames Cancer Registry database (1960,1996) for the South Thames Region. The changes in sex ratio and peak age of incidence are reported. Results: In the upper two-thirds of the oesophagus there was no significant change in the incidence rate, but the lower third of the oesophagus showed a marked rise for both sexes (average annual change +0·05 for men, +0·009 for women). For the gastric cardia, the incidence in males increased (average annual change +0·025), while in females it remained unchanged. Cancers of the oesophagogastric junction showed a clear increase for both sexes (average annual change +0·07 for men, +0·009 for women). There were changes in the sex ratio and peak age of incidence for all subsite cancers for both sexes. Conclusion: Over a 37-year period the incidence of cancer of the oesophagogastric junction increased threefold, while the incidence of cancers of the other subsites of the stomach decreased. Further studies are needed to investigate the aetiology of these changes. © 2001 British Journal of Surgery Society Ltd [source]


New classification of oesophageal and gastric carcinomas

BRITISH JOURNAL OF SURGERY (NOW INCLUDES EUROPEAN JOURNAL OF SURGERY), Issue 3 2001
K. Dolan
Background: The current International Classification of Diseases (ICD)-O classification of carcinomas of the oesophagus and stomach causes epidemiological and clinical confusion, particularly the use of the term cardia and the overlapping subsites described in the stomach. This study compared the epidemiological and clinical features of each subtype and subsite of carcinoma of the oesophagus and stomach to assess requirements for a new classification of these carcinomas. Methods: Data were extracted with appropriate validity checks on all cases of oesophageal and gastric carcinoma identified throughout the period 1974,1993 by the Merseyside and Cheshire Cancer Registry, which covers a population of 2·5 million. Comparison of all identifiable epidemiological and clinical features of adenocarcinomas at four different subsites, namely the upper two-thirds of the oesophagus, the lower third of the oesophagus, cardia and subcardia of the stomach, was performed. Results: There were 5322 primary carcinomas of the oesophagus and 10 535 carcinomas of the stomach registered between 1974 and 1993. The incidence of adenocarcinoma of the lower oesophagus and cardia trebled in males and doubled in females, whereas adenocarcinoma of the subcardia region of the stomach declined in both sexes. The incidence of adenocarcinoma of the lower oesophagus and of the cardia was similar for median age at diagnosis, male: female ratio, percentage of patients who smoked, and survival; both were significantly different from values for carcinoma of the subcardia in these respects. Conclusion: These data suggest that there is considerable overlap between adenocarcinomas of the lower oesophagus and adenocarcinomas currently classified as of the cardia. The authors believe this is due to the group of carcinomas classified as cardia consisting mainly of carcinomas that traverse the gastro-oesophageal junction. These carcinomas were different in all studied parameters from carcinomas of the stomach and should be classified separately from gastric carcinomas. A new subsite classification of oesophageal and gastric carcinomas is proposed that includes the gastro-oesophageal junction as a subsite of the oesophagus and that simplifies the subsite classification of the stomach into proximal, distal and overlapping. © 2001 British Journal of Surgery Society Ltd [source]


Anatomical variations of the sural nerve

CLINICAL ANATOMY, Issue 4 2002
Pasuk Mahakkanukrauh
Abstract An anatomical study of the formation of the sural nerve (SN) was carried out on 76 Thai cadavers. The results revealed that 67.1% of the SNs were formed by the union of the medial sural cutaneous nerve (MSCN) and the lateral sural cutaneous nerve (LSCN); the MSCN and LSCN are branches of the tibial and the common fibular (peroneal) nerves, respectively. The site of union was variable: 5.9% in the popliteal fossa, 1.9% in the middle third of the leg, 66.7% in the lower third of the leg, and 25.5% at or just below the ankle. One SN (0.7%) was formed by the union of the MSCN and a different branch of the common fibular nerve, running parallel and medial to but not connecting with the LSCN, which joined the MSCN in the lower third of the leg. The remaining 32.2% of the SNs were a direct continuation of the MSCN. The SNs ranged from 6,30 cm (mean = 14.41 cm) in length with a range in diameter of 3.5,3.8 mm (mean = 3.61 mm), and were easily located 1,1.5 cm posterior to the posterior border of the lateral malleolus. The LSCNs were 15,32 cm long (mean = 22.48 cm) with a diameter between 2.7,3.4 mm (mean = 3.22 mm); the MSCNs were 17,31 cm long (mean = 20.42 cm) with a diameter between 2.3,2.5 mm (mean = 2.41 mm). Clinically, the SN is widely used for both diagnostic (biopsy and nerve conduction velocity studies) and therapeutic purposes (nerve grafting) and the LSCN is used for a sensate free flap; thus, a detailed knowledge of the anatomy of the SN and its contributing nerves are important in carrying out these and other procedures.

Retrospective analysis of pre- and peri-operative imaging in confirmed proximal colonic cancers , possible implications for screening flexible sigmoidoscopy

COLORECTAL DISEASE, Issue 2 2009
R. Peravali
Abstract Objective, Faecal occult blood testing is being introduced for population screening in the United Kingdom. Flexible sigmoidoscopy may provide a viable alternative. The outcomes of the flexible sigmoidoscopy trial are awaited but the most obvious disadvantage is that only the lower third of the colon is examined and proximal pathology cannot be excluded. The relationship between proximal pathology and distal findings at flexible sigmoidoscopy is uncertain. The aim of this study was to determine the incidence of distal neoplasia in patients with confirmed proximal cancers of the colon. Method, All confirmed proximal colonic cancers (defined as those proximal to the splenic flexure) were identified from a database of pathology specimens at a single centre between January 1999 and August 2006. A retrospective analysis of preoperative and peri-operative mucosal imaging (contrast enema, colonoscopy and CT colonography) was conducted to identify any distal neoplasia in these patients. Results, A total of 348 patients were identified. Pre- or peri-operative mucosal imaging was identified in 231 (66%) and 49 (21%) had distal neoplasia. Nineteen (8%) of these patients would have gone on to have a colonoscopy based on the UK flexible sigmoidoscopy trial protocol and 92% of the cohort would not have had a colonoscopy. Conclusion, Nearly 80% of confirmed proximal cancers in our series did not have any demonstrable distal neoplasia. Only 8% of our cohort would have proceeded to colonoscopy. A very significant number of proximal cancers would not have been detected. [source]


On Being Holier-Than-Thou or Humbler-Than-Thee: A Social-Psychological Perspective on Religiousness and Humility

JOURNAL FOR THE SCIENTIFIC STUDY OF RELIGION, Issue 2 2002
Wade C. Rowatt
This research examined the association between religiousness and humility. Participants in Studies 1 and 2 completed measures of religiousness, socially desirable responding, and their own and other people's adherence to biblical commandments. Participants in Study 2 also rated how characteristic nonreligious positive and negative trait terms were of the self and others. Humility was operationalized as the magnitude of difference between individuals' evaluations of self and other. Overvaluing the self in relation to others or undervaluing others in relation to the self was considered evidence of less humility. Participants rated the self to be more adherent to biblical commandments than others (the holier-than-thou effect) and rated the self to be more positive and less negative than others (the self-other bias). In both studies, intrinsic religiousness was associated with an increase in the tendency to rate the self as more adherent to biblical commandments than others. Quest was associated with a slight decrease in the magnitude of the holier-than-thou effect. Religious motivations did not account for unique variation in the general self-other bias. Irrespective of motivations for being religious, however, highly religious people (i.e., upper thirds on general religiousness and religious fundamentalism) more so than less religious people (i.e., lower thirds on general religiousness and religious fundamentalism) rated the self to be better on nonreligious attributes than others.
