Santiago González-Moreno, Paul H Sugarbaker
OBJECTIVE: Appendectomy is an extremely common surgical procedure usually performed for an inflammatory process within this organ. Upon occasion, the pathology within the appendix is a neoplastic process which requires definitive oncologic management. METHODS: The optimal management strategies for appendiceal neoplasms were reviewed and pertinent literature critically evaluated. The technology for appendectomy for an inflammatory process and an appendectomy for a neoplastic process were compared and contrasted...

Amyand's hernia is a rare occurrence where the appendix is trapped within an inguinal hernia. Appendicitis within the hernia is even rarer. However, the presence of an appendiceal neoplasm in an inguinal hernia is almost unheard of with only two cases reported in the literature. We present an extremely rare case of an inflamed appendix within an Amyand's hernia, which was found to be a goblet cell type carcinoid tumour requiring further oncological resection and treatment.

INTRODUCTION: The main complications of appendicostomy are stenosis and stomal fecal leakage. Although many authors report that the appendix is naturally continent, it is recommended to perform a plication of the cecum with the appendix to prevent stomal fecal leakage. We present here the creation of a different continent mechanism. Our technique is advantageous when the anatomy, vascularity, or the length of the appendix does not allow for a standard plication procedure. DESCRIPTION OF OPERATIVE TECHNIQUE: During 2014-2016 we performed four appendicostomies in patients with anorectal malformations with fecal incontinence that requested an "Antegrade Continent Enema" procedure after a successful bowel management program in the Colorectal Center for Children of Mexico...

BACKGROUND: To determine if non-operative treatment is safe in children with acute appendicitis, we evaluated the incidence of unexpected findings after an appendectomy in children, and the influence they have on subsequent treatment. METHODS: A historical cohort study (January 2004-December 2014) was performed including children, aged 0-17 years, who underwent an appendectomy for the suspicion of acute appendicitis. Patients were divided based upon histopathological examination...

Caecal volvulus is a rare cause of intestinal obstruction. Caecal volvulus precipitated by acute appendicitis is even rarer. We report an unusual case of caecal volvulus with acute appendicitis as a cause. A 55-year female presented in surgical emergency with 3 days history of abdominal pain, distension and absolute constipation; and 2 days history of vomiting. Her past surgical history was significant for hysterectomy 5 years back. On examination, abdomen was distended and bowel sounds exaggerated. X-ray abdomen erect showed a single large air fluid level in the right hemiabdomen...

RATIONALE: Metastasis of cancer cells involves shedding from the primary tumor through various means to distant tissues and organs with continued growth and formation of new metastatic tumors of the same cancer type as the original tumor. The common sites for colon cancer metastases include the pelvis, retroperitoneal lymph nodes, liver, and lungs; Colon cancer metastases to the appendix are rare, as reported in this case. PATIENT CONCERNS AND DIAGNOSES: A 45-year-old man was admitted to our department with a 24-hour history of abdominal distension and incomplete obstruction...

Our contribution aims at clarifying and underlining a possible finding which can pose an interesting twist in routine appendix diagnostics: seeds in the appendiceal lumen, their histological aspects and their differential diagnosis with parasites. We work in a training centre with a large referral practice for gastrointestinal pathology and often the most banal cases are those which pose problems to junior or non-expert pathologists. This short study aims at providing simple iconographic tables, which are not at the moment available either in publications or on the web, with the most frequent seeds encountered in our routine practice or sent for second opinion...

REVIEW
LaGuinn P Sherlock, Craig Formby
Most clinicians approach the objective fitting of hearing aids with three goals in mind: audibility, comfort, and tolerance. When these three amplification goals have been met, the hearing aid user is more likely to adapt to and perceive benefit from hearing aid use. However, problems related to the loudness of sounds and reduced sound tolerance, which may or may not be reported by the aided user, can adversely impact adaptation to amplification and the individual's quality of life. Although there are several standardized questionnaires available to evaluate hearing aid benefit and satisfaction, there is no standardized questionnaire or interview tool for evaluating reduced sound tolerance and the related impact on hearing aid use...

Dichotomous endpoints in clinical trials have only two possible outcomes, either directly or via categorization of an ordinal or continuous observation. It is common to have missing data for one or more visits during a multi-visit study. This paper presents a closed form method for sensitivity analysis of a randomized multi-visit clinical trial that possibly has missing not at random (MNAR) dichotomous data. Counts of missing data are redistributed to the favorable and unfavorable outcomes mathematically to address possibly informative missing data...

Appendectomy is one of the most common emergency surgical procedures. Stump appendicitis is well-recognised entity has been described in the literature. Still, with recent advance in imaging technique, it remains as a clinical challenge for diagnosis and effective treatment. We present a case of 13-year-old boy who underwent laparoscopic appendectomy 3 months back and presented to us with acute abdomen associated with vomiting and fever. Imaging revealed the presence of a tubular residual inflamed tip of the appendix of size 4 cm laying in paracaecal position with approximately 50cc purulent collection around it...

BACKGROUND: Appendiceal cancers are rare and consist of carcinoid, mucocele, pseudomyxoma peritonei (PMP), goblet cell carcinoma, lymphoma, and adenocarcinoma histologies. Current treatment involves surgical resection or debulking, but no standard exists for adjuvant chemotherapy or treatment for metastatic disease. METHODS: Samples were identified from approximately 60,000 global tumors analyzed at a referral molecular profiling CLIA-certified laboratory. A total of 588 samples with appendix primary tumor sites were identified (male/female ratio of 2:3; mean age =55)...

Eisenbergiella gen. nov. was proposed in 2014 to describe an obligate anaerobic, structurally Gram-positive but Gram-stain-negative-appearing bacillus recovered from the blood culture of an elderly Israeli man. Here, we describe features for eight blood culture isolates as well one appendix-derived isolate, recovered from seven patients located in two Canadian provinces, which by 16S rRNA gene sequencing, were identifiable as Eisenbergiella tayi, the sole validly- named species in this genus. After whole genome sequencing, isolates were found to be essentially identical (96...

Acute appendicitis is the most common condition that presents with an acute abdomen needing emergency surgery. Despite this common presentation, correctly diagnosing appendicitis remains a challenge as clinical signs or positive blood results can be absent in 55% of the patients. The reported proportion of missed diagnoses of appendicitis ranges between 20% and 40%. A delay or mis-diagnosis of appendicitis can result in severe complications such as perforation, abscess formation, sepsis, and intra-abdominal adhesions...
