Fundoplication combined with mediogastric plication

BACKGROUND The purpose of this pilot study was to demonstrate the feasibility and procedural safety of laparoscopic fundoplication combined with mediogastric plication in patients with a body mass index of 32-35 kg/m(2). METHODS Sixteen patients underwent laparoscopic fundoplication combined with mediogastric plication. All procedures were performed with the patient under general anesthesia. The 1-year follow-up results encompassed gastroesophageal reflux disease recovery and excess weight loss. RESULTS The procedure time varied from 65 to 95 minutes. No serious procedure-related complications occurred. Gastroesophageal reflux disease-related symptoms resolved in all patients (P = .000). The excess weight loss was 10 ± 4 kg (58%) 1 year after the procedure. The 1-year follow-up excess weight was significantly less than the baseline excess weight (P = .000). The average body mass index decreased from 33.8 ± 1.9 kg/m(2) at baseline to 27.2 ± 1.7 kg/m(2) at 1 year (P = .02). Of the 16 patients, 14 had an excess weight loss of 62%, and 2 sweet-eaters had an excess weight loss of 33%. At 1 year of follow-up, the excess weight in those who smoked (n = 10) was greater than that of nonsmokers (n = 6; P = .02). However, smoking did not seem to significantly affect excess weight loss (P = .065). CONCLUSION Fundoplication combined with mediogastric plication produced a total recovery from gastroesophageal reflux disease and an excess weight loss of 62% in 87.5% of patients after 1 year of follow-up. This procedure is technically feasible, and no serious procedure-related complications occurred. The follow-up is ongoing to investigate the efficacy and long-term durability of the procedure.

Characteristics of nonalcoholic fatty liver disease induced in wistar rats following four different diets

BACKGROUND/OBJECTIVES The prevalence of nonalcoholic fatty liver disease (NAFLD) has increased worldwide in parallel with overnutrition characterized by high-fat and high-carbohydrate intake. Our objective was to establish, in 16 weeks, a model of NAFLD in Wistar pathogen-free rats following four dietary types. MATERIALS/METHODS Forty (6 weeks old) healthy Wistar male rats, weighing an average of 150 g were randomly divided into four groups of ten and assigned a diet with the same quantity (15 g/rat/day), but with different composition. The moderate-fat (MF) group was fed a moderate-fat diet (31.5% fat and 50% carbohydrates), the high-fat (HF) group was fed a fat-rich diet (51% fat), the high-sucrose (HS) group and the high-fructose (HFr) group were fed a carbohydrate-rich diet (61%). The carbohydrate contents of the HS group was composed of 60.3% sucrose while that of the HFr group was composed of 59.3% fructose. RESULTS At week 16, the HF group had the highest percentage of cells enriched in fat (40%) and the highest weight and liver weight (P < 0.05). The HFr group showed significantly higher levels of serum triglycerides, alanine aminotransferase and adiponectin at week 16 as compared to week 1 (P < 0.05). CONCLUSIONS The 15 g/rat/day diet composed of 51% fat or 61% carbohydrates enriched mainly in fructose may induce characteristics of NAFLD in rats.

Characteristics of incident female breast cancer in Lebanon, 1990–2013: Descriptive study of 612 cases from a hospital tumor registry

Despite the fact that breast cancer is a major health issue, very few studies describe its characteristics in the Arab world or the Middle East, particularly in Lebanon. We report in this article a retrospective pilot study of the characteristics of breast cancer in Lebanon. The pathological characteristics of 624 patients diagnosed between 1990 and 2013 randomly chosen from the archives of an oncology clinic affiliated to Hotel Dieu de France Hospital are analyzed. The mean age at diagnosis is 54.6±13.4 years with 43% diagnosed before the age of 50 years. The infiltrative ductal carcinoma represents the major pathological subtype. One third of the tumors had a size of more than 2 cm at diagnosis. Estrogen-receptors are positive in more than 50% of our patients and Her2-neu is overexpresssed in 30%. Luminal A represents 45.5% and the triple negative subgroup constitutes only 8.3%. Breast cancer in Lebanon is evolving to a more indolent disease. Therefore, public awareness and institution of screening programs are required. These programs should be based on national epidemiological data and necessitate the activation of the national cancer registry.

Does diclofenac increase the risk of cervical necrotizing fasciitis in a rat model

Non‐steroidal anti‐inflammatory drugs (NSAIDs) are known for aggravating in vitro infections and were reported in many cases of cervical necrotizing fasciitis (CNF). We developed a rat model of CNF, mimicking as closely as possible the human‐CNF, to study the effect of a NSAIDs, diclofenac, as a promoting factor. Twenty rats were injected bilaterally in the neck with peptostreptococcus and with a fresh saliva specimen for another 20 rats. Half of each group was given an intramuscular injection of 4 mg/kg diclofenac at the time of inoculation and 24 h later, and the other half saline injections; rats were killed at day 7 and clinical, bacterial and histological studies were performed to assess the infectious process and the incidence of CNF. No statistically significant difference was found between groups treated with diclofenac vs. the saline injection groups. However a significant correlation was noted between clinical observation, bacterial density and histological signs of inflammation. CNF has a high mortality rate and the use of NSAIDs in conditions potentially leading to CNF is very common. However, our rat model does not support the hypothesis of a promoting role of diclofenac which was occasionally suggested in the medical literature. This study suggests that diclofenac does not seem to increase the risk of occurrence of CNF. Nonetheless, NSAIDs can mask inflammatory signs of an already spreading CNF.

Prediction of preterm delivery by second trimester inflammatory biomarkers in the amniotic fluid

OBJECTIVE To search for a correlation between mid-pregnancy altered levels of inflammatory markers and preterm delivery. METHODS A prospective cohort series included 39 patients undergoing amniocentesis one additional milliliter of amniotic fluid (AF) was stored for later dosage of interleukin-6 (Il-6), matrix metalloproteinase-9 (MMP-9), glucose and C-reactive protein (CRP). Maternal serum CRP and glucose levels were also obtained. Exclusion criteria were multiple pregnancies, chorioamnionitis, group B streptococcus colonization, bacterial vaginosis and cases with proven aneuploidy. We searched for correlation between AF and plasmatic markers and also for a difference between patients with term and preterm delivery. RESULTS 33 participants were eligible and one third had preterm delivery. Levels of the plasmatic biomarkers did not correlate with the AF biomarkers except for plasmatic glucose and AF IL-6 levels (r=0.350; p=0.016). The levels of all AF biomarkers did not differ significantly between the pre-term and the term groups (p>0.05). The optimal screening cutoffs for identifying pregnancies at risk were different than the ones initially indicated. CONCLUSION Mid-pregnancy amniotic fluid biomarker levels do not correlate with preterm delivery. Plasma CRP is not correlated with these markers. Cutoff levels suggested are sparse and heterogeneous. Larger studies are needed before advising routine measurement of these markers.

Validation Study of a Portable Home Trainer Using a Pad for Laparoscopic Practice

The aim of this study was to describe and validate a homemade laparoscopic trainer. The abdominal cavity is simulated within a 3-mm-thick stainless steel model. Thirty-four participants were evaluated in a pilot study to validate our model. Participants were divided into experts (n = 19) and novices (n = 15) to perform basic and complex laparoscopic skills. The comparison between the homemade trainer (HT) and the standard laparoscopic trainer showed no significant differences for the 2 tasks performed for each group (P > .05). The experts’ performance of the 2 tasks was statistically different from the novices (P < .05) on both trainers. Both experts (84%) and novices (87%) approved the HT as an effective home trainer. Our HT seems to fulfill the conditions of performing the basic and complex laparoscopic psychomotor skills at a low cost and similar efficiency.

First Description of a Primitive Neuroectodermal Tumor Arising in the Nose

We report the case of a 12-year-old girl, who consulted us with one-year history of an 8 mm nose lesion that was painless and firm upon palpation. The lesion was resected conservatively. Immunohistochemistry was in favor of a primitive neuroectodermal tumor (PNET)/Ewings sarcoma lesion, excluding epithelial, lymphoid, and other tumors. After a second resection, our patient was referred to chemotherapy and has already undergone 9 cycles out of 14. The patient is to date with no evidence of persistent or recurrent disease. To our knowledge, this is the first description of a PNET arising in the nose.

Data on clinical significance of second trimester inflammatory biomarkers in the amniotic fluid in predicting preterm delivery.

In this article second trimester amniotic fluid biomarkers are measured for correlation with preterm delivery. One additional milliliter of amniotic fluid is collected during amniocentesis for dosages of IL-6, MMP-9, CRP and glucose levels, along with maternal serum CRP and glucose. MMP-9 and Il-6 levels were measured with the corresponding Human QuantikineR ELISA Kit (R&D systems) according to the instructions provided by the manufacturer. Cut-off values for AF MMP-9 and IL-6 were fixed by the kit sensitivity thresholds. Data includes ROC curves for glucose (Fig. 1), IL-6 (Fig. 2) and MMP-9 (Fig. 3), aiming to search for sensitivity and specificity in the prediction of premature delivery. Statistical analyses are performed with SPSS v20.0 software. Statistical significance is determined using the Mann–Whitney and one way ANOVA test. The association with preterm delivery is performed using a two proportions test. Correlations are measured using the Pearson׳’s coefficient. A p value<0.05 is considered statistically significant. The data is presented in the figures provided. Data relied on a previous publication “Prediction of preterm delivery by second trimester inflammatory biomarkers in the amniotic fluid” (A. Kesrouani, E. Chalhoub, E. El Rassy, M. Germanos, A. Khazzaka, J. Rizkallah, E. Attieh, N. Aouad, 2016) [1].

From the dry lab to the operating room: the first transferability study of hysteroscopic skills

ObjectiveThe aim of this study is to prove that a short dry lab training prior to the surgery is efficient to acquire basic hysteroscopic skills and that these skills are transferable directly to the operation theater.MethodsThirty-nine gynecologists who never attended a training course or practiced hysteroscopy before were evaluated. Participants were randomly divided into trainees (n = 21) and control (n = 18). Trainees attended a short time dry lab prior the exposure to the OR. The controls went directly to the OR. Participants were asked to identify the different landmarks of the uterine cavity and to perform a punch biopsy under the supervision of a gynecologist expert in hysteroscopy. A video recording for all the exercises was done, and showed independently to two expert surgeons in hysteroscopy for evaluation. The experts were also asked to distinguish between the trainees and the control.ResultsFor both experts, the trainees’ performance was statistically better than that of the controls (p < 0.001) for the identification of the uterus land marks and the punch biopsy. The two experts identified 80.9 and 85.7%, respectively, of the trainees. The participants’ subgroup ID and the experts’ identification were statistically correlated (p < 0.001).ConclusionA short time dry lab is efficient to acquire basic hysteroscopic skills and these skills are transferable directly to the OR.

An Unusual Case of Oral Metastasis from Rectal Adenocarcinoma Precipitated by Iatrogenicity.

Dear Editor: Colorectal cancer is the third most common cancer and is characterized with a relatively better overall survival compared to other cancers. The current therapeutic advances in this tumor are being developed with the better understanding of its pathophysiology. It is known that colorectal adenocarcinoma spreads primarily via the lymphatic route followed by the hematogenous route; the liver and lungs being the most affected organs. Oral and facial metastasis is a rare finding that is usually associated with a widespread disease and very poor prognosis. However, in the absence of particular symptoms, its diagnosis is quite challenging [1]. We report the case of previously healthy 36-years-old woman that presented to our clinic for an isolated hematochezia without other systemic symptoms. Investigations revealed locally advanced rectal adenocarcinoma that was treated with neoadjuvant chemoradiotherapy, followed by a proctectomy, and 5-FU-based chemoradiotherapy. On follow-up 2 years later, she had developed liver metastasis and received therefore a combination of folinic acid, fluorouracil, and oxaliplatin (FOLFOX) with bevacizumab before proceeding to a partial hepatectomy. The patient was maintained on a combination of folinic acid, fluorouracil, and irinotecan (FOLFIRI) with cetuximab. Throughout the year, the patient was totally asymptomatic, with undetectable carcinoembryonic antigen levels and normal abdomino-pelvic imaging. Upon the appearance of an exophytic gingival mass over her first left premolar, the patient underwent a full examination of the oral cavity by her dentist who performed a transgingival trucut biopsy that confirmed the diagnosis of metastatic rectal adenocarcinoma. A radical resection of the mandibular mass was done without restaging imaging but she developed a 5-cm mass under her tongue 2 weeks later. She complained of dysphagia, disfigurement, and a left diplopia. Facial CT scan showed left sub-arachnoidal and facial bones metastases. The patient was started on chemoradiotherapy with FOLFIRI and bevacizumab. Unfortunately, the disease progressed and the patient died 3 months later.
