Pancreatic Cyst Size Measurement on Magnetic Resonance Imaging Compared to Pathology.

Background: While multiple cyst features are evaluated for stratifying pancreatic intraductal papillary mucinous neoplasms (IPMN), cyst size is an important factor that can influence treatment strategies. When magnetic resonance imaging (MRI) is used to evaluate IPMNs, no universally accepted sequence provides optimal size measurements. T2-weighted coronal/axial have been suggested as primary measurement sequences; however, it remains unknown how well these and maximum all-sequence diameter measurements correlate with pathology size.

Barriers Associated With Missed Palliative Care Telehealth Visits.

: The COVID-19 pandemic accelerated the adoption of telehealth in palliative care. While this technology showed efficiencies in healthcare delivery, it also unmasked inequalities affecting the socially disadvantaged. : To identify factors associated with missed telehealth visits.

Air quality in Canadian port cities after regulation of low-sulphur marine fuel in the North American Emissions Control Area.

Large marine vessels have historically used high-sulphur (S) residual fuel oil (RFO), with substantial airborne releases of sulphur dioxide (SO₂) and fine particulate matter (PM) enriched in vanadium (V), nickel (Ni) and other air pollutants. To address marine shipping air pollution, Canada and the United States have jointly implemented a North American Emissions Control Area (NA ECA) within which ships are regulated to use lower-sulphur marine fuel or equivalent SO scrubbers (i.e.

Community-led HIV self-testing for men who have sex with men in Lebanon: lessons learned and impact of COVID-19.

Background: In Lebanon, HIV is concentrated in both native and refugee communities of men who have sex with men (MSM). For over 10 years, the National AIDS Program (NAP) has offered HIV voluntary counselling and testing through a partnership with nongovernmental organizations (NGOs). In 2018, implementation of HIV self-tests (HIVST) was introduced, and this self-care intervention has been further scaled up during the coronavirus disease 2019 (COVID-19) pandemic.

Multiphase computed tomography radiomics of pancreatic intraductal papillary mucinous neoplasms to predict malignancy.

Background: Intraductal papillary mucinous neoplasms (IPMNs) are non-invasive pancreatic precursor lesions that can potentially develop into invasive pancreatic ductal adenocarcinoma. Currently, the International Consensus Guidelines (ICG) for IPMNs provides the basis for evaluating suspected IPMNs on computed tomography (CT) imaging. Despite using the ICG, it remains challenging to accurately predict whether IPMNs harbor high grade or invasive disease which would warrant surgical resection.

Conditional survival after diagnosis with malignant brain and central nervous system tumor in the United States, 1995-2012.

General population-based survival statistics for primary malignant brain or other central nervous system (CNS) tumors do not provide accurate estimations of prognosis for individuals who have survived for a significant period of time. For these persons, the use of conditional survival percentages provides more accurate information to estimate potential outcomes. Using information from the National Cancer Institute's Surveillance, Epidemiology and End Results (SEER) program from 1995 to 2012, conditional survival percentages were calculated for 1 or 5 years of additional survival for all primary malignant brain and CNS tumors overall and by gender, race, ethnicity and age.

Descriptive epidemiology of pituitary tumors in the United States, 2004-2009.

Object: Pituitary tumors are abnormal growths that develop in the pituitary gland. The Central Brain Tumor Registry of the United States (CBTRUS) contains the largest aggregation of population-based data on the incidence of primary CNS tumors in the US. These data were used to determine the incidence of tumors of the pituitary and associated trends between 2004 and 2009.

The descriptive epidemiology of atypical teratoid/rhabdoid tumors in the United States, 2001-2010.

Background: Atypical teratoid/rhabdoid tumor is a rare malignant CNS tumor that most often affects children ≤ 3 years old. The Central Brain Tumor Registry of the United States contains the largest aggregation of population-based incidence data for primary CNS tumors in the US. Its data were used to describe the incidence, associated trends, and relative survival after diagnosis of atypical teratoid/rhabdoid tumor.

Additive effect of phosphodiesterase inhibitors in control of pulmonary hypertension after congenital cardiac surgery in children.

Objective: Control of residual pulmonary arterial hypertension (PAH) after closure of left to right shunts in children is still a challenging issue. The purpose of this study was to compare the effect of two phosphodiesterase inhibitors in pediatric cardiac surgical patients.

Methods: A total of 48 postoperative children were enrolled in the study between 2008 and 2010.

[Experimental teaching program on cooperation between "Sapienza" University of Rome and the University Hospital "Le Bon Samaritain" in N'Djamena, Chad].

Background: The shortage of essential surgical care in sub-Saharan Africa is a worldwide problem. Lack of healthcare workers, surgeons and very limited resources are the reason for this critical health crisis. Furthermore in Africa many physicians as soon as they get a degree emigrate in more attractive countries.

[Subtotal or total colectomy as surgical treatment of left-sided occlusive colon cancer].

Introduction: The treatment of acutely obstructed carcinoma of the left colon and sigmoid still represents a matter of controversy. The aim of this study was to assess retrospectively the results of its management by emergency subtotal or total colectomy with primary anastomosis.

Materials And Results: Sixty-seven patients were reviewed.

The volunteer program in a Children's Hospice.

Background: Canuck Place Children's Hospice (CPCH) is regarded as one of the leading pediatric palliative care systems in the world. Since 1995, it has been providing hospice care free of charge to children and their families living with life-threatening conditions. The pediatric palliative hospice is a relatively new practice in health care, in comparison to the longstanding adult model.

[Creation of the St Joseph University Faculty of Medicine in Beirut: 125 years of Franco-Lebanese healthcare cooperation].

The Mediterranean--mare nostrum--has always been a cradle of exchanges for the different inhabitants of its shores, as highlighted by myths and legends dating back to antiquity. Cooperation between France and Lebanon expanded markedly in the 17th century and has continually expanded since, in fields such as education, through initiatives launched by the French government and by religious institutions. The Faculty of Medicine is an excellent example.

Perforation of the rectum and colon during barium enema examination. Report of four cases.

Background: The barium enema examination (BEE) is an important diagnostic study and considered to be safe without adverse effects. Perforation of the bowel is rare but is the most frequent complication of BEE and can be life-threatening.

Study Design: We report four cases of barium extravasation due to BEE treated at our institution, three rectal perforations and one perforation in the descending colon.

Use of fine-needle aspiration cytology and frozen section in the management of nodular goiters.

Background: This study evaluates the role of frozen section (FS) in surgical decisions for nodular thyroid disease when a preoperative fine-needle aspiration cytology (FNAC) is available.

Material And Method: The charts of 113 patients who underwent thyroidectomy for nodular goiter were reviewed. Each patient underwent FNAC, FS, or both.

[A rare manifestation of hypothyroidism: intestinal obstruction. Report of 2 cases and review of the literature].

Gastrointestinal manifestations of hypothyroidism are unfrequent. They consist particularly in hypomotility, intestinal atony, and pseudoobstruction. A high index of suspicion must exist, especially in elder subjects, in order to avoid unnecessary and even harmful investigation and intervention.

Benign disease of the thyroid gland and vocal fold paralysis.

Development of vocal fold paralysis in the presence of thyroid disease is strongly indicative of thyroid cancer, and requires surgical exploration. At the same time, vocal fold paralysis does not relieve the surgeon of his obligation to identify and preserve the recurrent laryngeal nerves, since the cause of the paralysis may be a benign disease, with a fair chance of functional recovery after surgery. We hereby report a case of recurrent laryngeal nerve palsy secondary to a multinodular goitre.

[Laparoscopic adrenalectomy for pheochromocytoma. Case report and review of the literature].

Laparoscopic surgery has a wide application in general surgery. Since the first laparoscopic adrenalectomy, this approach has quickly been adopted, and increasing numbers are being reported. The small size of the adrenal gland, the benign nature of most adrenal tumors and the difficulty in reaching the organ via open means make resection of this gland particularly amenable to the laparoscopic approach.

[Radiation-induced esophageal cancer. Presentation of a case and review of the literature].

Esophageal cancer induced by radiation is uncommon. Irradiation of the head, the neck, the chest and the abdomen may cause an esophageal cancer several years later. Therefore, regular gastroscopy and biopsy of esophageal mucosa are strongly recommended in symptomatic patients.

[Parathyroidectomy under local anesthesia. First two cases in Lebanon and review of the literature].

The routine use of automated techniques to measure serum calcium levels have made disease states of the parathyroid gland a common endocrinologic problem. Because of the low sensitivity and specificity of early radiologic techniques to identify enlarged parathyroid glands, and because skilled endocrine surgeons report success rates of > 95% in identifying abnormal parathyroid glands, historically most parathyroid glands surgery consisted in a large cervicotomy under general anesthesia without preoperative localization. However, the development of sophisticated imaging techniques has now made it possible to identify the abnormal gland in a significant number of patients, leading some surgeons to choose unilateral neck exploration under local anesthesia for primary hyperparathyroidism.

[Metastatic implants after laparoscopic cholecystectomy in unsuspected gallbladder cancer. A case report and review of the literature].

A gallbladder carcinoma, diagnosed preoperatively, is a counter-indication for laparoscopic cholecystectomy. When this cancer is not diagnosed and laparoscopic surgery is undertaken, neoplastic dissemination may occur along the trocars pathways which renders the prognosis even worse. The most probable explanation of the dissemination is a seeding of sloughed cancerous cells onto abdominal wall during exsuflation.

[Unusual metastases of breast cancer].

The breast cancer is the common cancer in female. The metastasis may occur any where in the body. The common sites are in the lymph nodes, the bones, the chest, the liver and the brain.
