Ectopic pancreas in a 16-year-old male during bariatric surgery: A rare case in the medical literature.

INTRODUCTION AND IMPORTANCE: Obesity is a global epidemic, and bariatric surgery is an effective treatment. During this surgery, rare abnormalities in the small intestine, like ectopic pancreas (EP), can be found. CASE PRESENTATION: A 16-year-old male presented at the surgical clinic with a complaint of morbid obesity, weighing 140 KG. Since he was unable to commit to a diet, bariatric surgery was performed. During the surgery, the gastrointestinal tract was examined, and an incidental finding was noted in the wall of the proximal jejunum. The histopathology report revealed that the excisional biopsy was a complete EP in the proximal jejunum. The patient was discharged from the hospital on the first postoperative day, and his condition remained stable. CLINICAL DISCUSSION: Our case of EP stood out due to its larger size, measuring 3.5 cm in diameter, while EP lesions are typically smaller, despite its size, the patient did not experience any symptoms. EP is more commonly found in individuals between 40 and 50 years old, with a higher incidence in males. However, our patient is only 16 years old. CONCLUSION: Surgical resection is the most effective treatment, preventing malignant transformation and future complications. To the best of our knowledge, this is the first documented case of incidentally detected heterotopic pancreatic tissue in jejunum during a bariatric procedure in Syria, and it is also the fourth case in the medical literature.

Venomous gland transcriptome and venom proteomic analysis of the scorpion Androctonus amoreuxi reveal new peptides with anti-SARS-CoV-2 activity.

The recent COVID-19 pandemic shows the critical need for novel broad spectrum antiviral agents. Scorpion venoms are known to contain highly bioactive peptides, several of which have demonstrated strong antiviral activity against a range of viruses. We have generated the first annotated reference transcriptome for the Androctonus amoreuxi venom gland and used high performance liquid chromatography, transcriptome mining, circular dichroism and mass spectrometric analysis to purify and characterize twelve previously undescribed venom peptides. Selected peptides were tested for binding to the receptor-binding domain (RBD) of the SARS-CoV-2 spike protein and inhibition of the spike RBD - human angiotensin-converting enzyme 2 (hACE2) interaction using surface plasmon resonance-based assays. Seven peptides showed dose-dependent inhibitory effects, albeit with IC50 in the high micromolar range (117-1202 µM). The most active peptide was synthesized using solid phase peptide synthesis and tested for its antiviral activity against SARS-CoV-2 (Lineage B.1.1.7). On exposure to the synthetic peptide of a human lung cell line infected with replication-competent SARS-CoV-2, we observed an IC50 of 200 nM, which was nearly 600-fold lower than that observed in the RBD - hACE2 binding inhibition assay. Our results show that scorpion venom peptides can inhibit the SARS-CoV-2 replication although unlikely through inhibition of spike RBD - hACE2 interaction as the primary mode of action. Scorpion venom peptides represent excellent scaffolds for design of novel anti-SARS-CoV-2 constrained peptides. Future studies should fully explore their antiviral mode of action as well as the structural dynamics of inhibition of target virus-host interactions.

A late diagnosis of primary intestinal lymphangiectasia in a Syrian girl.

Primary intestinal lymphangiectasia is a rare disease that affects children and young adults, causing mainly gastrointestinal disorders that lead to edema and immunologic abnormalities. The majority of patients typically present bilateral lower limb edema, along with pericarditis, pleural effusion, or chylous ascites. The goal of the treatment is to restrict the consumption of long-chain fats and administer a formula that includes protein and medium-chain triglycerides. Here, we report 11-year-old Syrian girl presented to the hospital with 2 years history of diarrhea and generalized edema. Furthermore, investigation showed ascites and pleural effusion. The disease was detected by several biopsies from duodenum that showed dilation of the lymph vessels within the lamina propria without any evidence for inflammation. She was managed by modifying her diet and albumin transfusion, which caused significant improvement in the child's condition.

A rare case of small bowel obstruction caused by Meckel's diverticulum: case report.

Meckel's diverticulum MD is the most common congenital deformity of the gastrointestinal tract. It has a very low reported incidence. We reported a 9-year-old child complaining of symptoms of small bowel obstruction. He had no medical or surgical history. There is no signs of peritonitis and appendicitis. Simple abdominal X-ray diagnosed the obstruction, during surgery we found an MD located 30 cm from the ileocecal valve, fibrous band may be as complication for MD to the anterior abdominal wall at the umbilicus, the small intestines were wrapped around the band, causing the obstruction. The MD and the band were excised with end-to-end anastomosis. We diagnosed our case during surgery. Early surgery is important to preserve bowel from gangrene or necrosis. The patient's well-being improved, and he was discharged from the hospital in good condition.

Strangulated femoral hernia with appendicitis: A rare case of De Garengeot's hernia.

INTRODUCTION AND IMPORTANCE: De Garengeot hernia is a rare case of a femoral hernia. It occurs when a femoral hernia contains a vermiform appendix that may be inflamed and sometimes necrotic, and this requires emergency surgery. However, the hernia is usually discovered by chance in the operating theater, which poses an additional challenge for surgeons. CASE PRESENTATION: A 64-year-old man presented with a 1-week history of a painful right groin lump. The lump is irreducible and painful on exert a week ago. Ultrasound imaging showed a 1.5 × 2 cm loculated turbid liquid collection containing an edematous intestinal loop measuring 8 mm in diameter that was suspected to be the vermiform appendix. Therefore, appendectomy was performed through the hernia sac. After that, the hernia was repaired using the McVay technique and 2.0 nylon sutures. One day after the operation, the patient was discharged, and he returned to the clinic after 10 days without any complications. CLINICAL DISCUSSION: The patient has a history of chronic obstructive pulmonary disease (COPD), which is a risk factor for a hernia. He had to live with the right femoral hernia for ten years until it became painful and irreversible. Ultrasound revealed what appears to be an appendix. To avoid possible consequences of complicated appendicitis and strangulated hernia, emergency surgery was the appropriate choice for our patient case. CONCLUSION: The presence of an appendix in the femoral hernia poses a diagnostic and therapeutic challenge to surgeons, due to the atypical clinical picture and the lack of efficacy of radiographic methods in diagnosing the condition.

Chemoenzymatic Late-Stage Modifications Enable Downstream Click-Mediated Fluorescent Tagging of Peptides.

Aromatic prenyltransferases from cyanobactin biosynthetic pathways catalyse the chemoselective and regioselective intramolecular transfer of prenyl/geranyl groups from isoprene donors to an electron-rich position in these macrocyclic and linear peptides. These enzymes often demonstrate relaxed substrate specificity and are considered useful biocatalysts for structural diversification of peptides. Herein, we assess the isoprene donor specificity of the N1-tryptophan prenyltransferase AcyF from the anacyclamide A8P pathway using a library of 22 synthetic alkyl pyrophosphate analogues, of which many display reactive groups that are amenable to additional functionalization. We further used AcyF to introduce a reactive moiety into a tryptophan-containing cyclic peptide and subsequently used click chemistry to fluorescently label the enzymatically modified peptide. This chemoenzymatic strategy allows late-stage modification of peptides and is useful for many applications.

A rare case of terminal ileum diverticulosis in a-32-year old woman.

Introduction: and importance: Acquired small bowel diverticulosis is rare 1% and the ileum is the less frequent occurring site 15%. Most cases were multiple and asymptomatic. This is the first case of perforated terminal ileum diverticula in a 32-year-old woman and successfully managed surgically. Case presentation: We describe a rare case of terminal ileal diverticulosis, one of the diverticula was perforated, in a 32-year-old female who presented with a 2-days history of sudden epigastric and periumbilical pain and had been managing surgically. At surgery, we found multiple diverticula, one of them was perforated. Microscopically, the specimen confirmed that the diagnosis was diverticulosis. Conclusion: Diverticulosis should be included in the differential diagnosis of a sudden epigastric and periumbilical pain even in this age.

A rare case of benign multicystic peritoneal mesothelioma misdiagnosed as hydatid cyst found in the liver parenchyma and abdomen cavity of a male with asbestos exposure.

BACKGROUND: Benign Multicystic Peritoneal Mesothelioma (BMPM) is one of the rarest diseases in medicine with only more than 200 cases worldwide. This paper aims to report a case of Benign Multicystic Peritoneal Mesothelioma that strangely arose from the liver and was long treated as Hydatid cyst. The case also had many risk factors including asbestos exposure that had not yet been linked with Benign Multicystic Peritoneal Mesothelioma. CASE PRESENTATION: We report a case of a 62 years old male with a history of a perforated peptic ulcer and a cystic mass in the liver that was misdiagnosed as hydatid cyst 7 years ago. He presented with generalized abdominal pain and bloating. Image studies showed many cystic formations filled with clear fluid. An en bloc surgery was performed and a pathologic study showed a multiloculated mass lined by flat or cuboidal epithelium leading to the diagnosis of BMPM. A follow up was scheduled after 3 months revealed total recurrence. CONCLUSION: BMPM resembles many other cystic lesions in the abdomen and should be taken into consideration when dealing with nontypical cystic formations. Its diagnostic and treatment methods are still hazy making this disease difficult to approach.

Syrian medical, dental and pharmaceutical publication in the last decade: A bibliometric analysis.

BACKGROUND: Scientific research has an essential role in building up the basics of public health and clinical care. As a developing country, Syria has a limited contribution to scientific research. Besides, the current Syrian crisis has inflicted severe damage to the infrastructure of the country, which, in turn, negatively affected the scientific sphere. This study examines the scientific publishing in Syria from 2011 until 2020. It aims to define the real and deep reasons for the slow-down in publication to get over them, push Syria to keep track of the latest updates, and take its place in scientific research. METHODS: We conducted a bibliometric analysis of articles published in (PubMed and Scopus) Databases from 1/1/2011 until 26/12/2020, using the following search terms (("Syrian Arab Republic") OR (Syria) OR (Syrian)) limiting the search to (Affiliation) fields. RESULTS: Syrian medical, dental and pharmaceutical institutions published 1403 papers from 2011 until 2020. There were only 55 papers in 2011, and a peak with 180 papers in 2018. Besides, publications in the last 4 years were 1.135 times more than publications in the last 6 years. CONCLUSION: We noticed a peak in quantity of Syrian medical, dental and pharmaceutical publications in the last decade. Accordingly, we recommend enhancing research skills, paying more attention to the quality of researches, and holding research workshops and Evidence Based conferences to enhance the scientific endeavor.

Cholecystocutaneous fistula incidence, Etiology, Clinical Manifestations, Diagnosis and treatment. A literature review.

Cholecystocutaneous Fistula (CCF) is a type of external biliary fistula, which connects the gallbladder with the skin. Thilesus first described this phenomenon in 1670. There is usually a history of calculi in the gallbladder or neglected gallbladder disease. The incidence of CCF is rare, most patients are elderly females with the mean age of 72.8 years old. They usually present with chronic calculus cholecystitis or a history of a previous surgical intervention. US, CT, MRI, MRCP and (CT or X-ray) fistulogram are used to confirm the diagnosis. CT was more significant than US in identifying the track of the fistula and the fluid that runs throw it. CCF patients presented with systemic symptoms (fever, nausea and vomiting) or local symptoms. RUQ region is the most common site of external opening. Open cholecystectomy with excision of the fistulous tract is considered an acceptable option for treatment and it is curative in most cases. However, laparoscopic approach can be another option with experience surgeons.

A Neglected Case of Multifocal Liposarcoma Presented in Five Different Sites in a Syrian Woman: A case report.

INTRODUCTION: Multifocal soft tissue sarcoma is a rare clinical entity occurring in 1 % of patients with extremity soft tissue sarcoma and in 4.5 % of patients with liposarcoma. Multifocal disease may arise either synchronously or metachronously and has been associated with poor prognosis. CASE PRESENTATION: Herein, we report a rare case of a Syrian woman patient with six different foci of liposarcoma in five sites at the time of diagnosis. DISCUSSION: Liposarcomas are currently classified into four different subtypes based on histologic or genetic analysis according to the World Health Organization (WHO), including cell-differentiated, dedifferentiated, myxoid, and pleomorphic. In the present work, we report a neglected patient with a multicentric round cell liposarcoma in five different sites. CONCLUSION: Medicine cannot provide much care for these advanced cases of multicentric liposarcoma so far. Therefore, more research should be conducted to improve the ability to manage these entities and to identify potential novel therapies.

A Syrian Child with Intussusception Caused by a Diffuse Large B-Cell Lymphoma.

Intussusception is the invagination of a segment of the bowel into an adjacent segment. Here, we describe a middle-eastern case of an 11-year-old boy who presented to our institution with an intussusception caused by lymphoma but with nonspecific symptoms such as acute abdominal pain and a history of weight loss. His abdominal ultrasound and computed tomography (CT) showed ileocolic intussusception with a mass leading it. We resected the mass with the affected bowel and related lymph nodes, and the histological examination showed features of diffuse large B-cell Non-Hodgkin's lymphoma (an uncommon histologic type in the Middle East). Known as intussusception, this urgent condition could distress infants and young children. However, in older children, the presentation is subtler. So, a lead point should be observed and the chance of malignancy should be kept in mind.

Jejunal intussusception in an adult due to multiple lipomas: a rare case report from Syria.

Intussusception in adulthood is an uncommon medical condition. Multiple lipomas are a very rare cause of intussusception, and the jejunum is the least common location of lipoma. We report an unusual case of a 37-year-old man presented with non-specific symptoms. Computed tomography of the abdomen revealed a proximal jejunal loop distention. Laparoscopy revealed a jejunal intussusception 40 cm distal to treitz ligament. We switched to open surgery after failure of laparoscopic reduction which showed multiple lipomas as the cause of the intussusception. We resected a segment of 35 cm and reanastomosed the bowel. Three days later, the patient was discharged with uneventful recovery.

A Rare Case of an Advanced Gastric Adenocarcinoma in a Teenage Syrian Boy.

In this report, we describe a case of a gastric cancer in young age group with delayed diagnosis and poor prognosis. We report a rare case of a 16-year-old teenager with an advanced moderately differentiated gastric adenocarcinoma without any relevant history. He presented mainly with dysphagia, postprandial vomiting, and eventually hematemesis. On exploratory laparotomy, the tumor was in advanced stage, the excision was not performed, multiple biopsies and a feeding jejunostomy were done, and the patient was referred to receive a palliative therapy. Reporting such cases introduces a better understanding of the relation between gastric cancer and young ages.

Retained gastric band port and tube 5 years after gastric band removal and laparoscopic Roux-en-Y gastric bypass: a case report.

BACKGROUND: While LAGB has become uncommon in the bariatric surgery practice, band removal with or without revision surgery is still common. Retained postoperative foreign body, of which surgical sponges are the most common, is a rare condition. We report a rare case of retained gastric band port and the attached tube. CASE PRESENTATION: A 31-year-old Caucasian female presented to the outpatient clinic, 5 years after her last surgery, complaining of a left upper quadrant abdominal mass over the last 2 years. She had a history of 2 weight loss operations. She had no significant family history nor smoking. CT of the abdomen and pelvis revealed a retained foreign body. On exploration, the port with 10 cm of the connected tube was found and removed through a small incision without laparotomy. The patient made an uneventful recovery. CONCLUSION: A bariatric surgeon should be involved in the evaluation of any patient who complains of abdominal pain and/or palpable mass if she/he has a previous weight loss procedure because the bariatric surgeon is fully aware of the possible complications of the bariatric surgeries.

Spinal-epidural Abscess Presenting as an Acute Abdomen in a Child: A Case Report and Review of the Literature.

Abdominal presentations in patients with spinal-epidural abscess (SEA) are not uncommon. However, it needs to be continually emphasized that the atypical presentations of these diseases could delay the timely diagnosis and consequently prompt management, which threatens spinal cord, leading to potential to paralysis or even death. We report a case of a young girl who presented with abdominal pain and fever. The diagnosis of SEA was unfortunately so delayed that the patient did not show any functional recovery postoperatively. This report aims to highlight the importance of high level of clinical suspicion to recognize an atypical presentation of the SEA. Moreover, the fully detailed history-taking and physical examination are of paramount importance. Spinal underlying pathologies should always be considered as a cause of abdominal pain, especially in children.

Successful Elimination of Gallbladder Ascariasis by Conservative Therapy, Followed by Cholecystectomy due to Developing Cholecystitis.

BACKGROUND: Ascaris lumbricoides is the most common parasitic infection in human. The worm is usually located in the small intestine, but may invade into the pancreatic or biliary tree, but rarely into gallbladder because of the anatomic features of the cystic duct. CASE PRESENTATION: We report a case of gallbladder ascariasis that was diagnosed incidentally in a 70-year-old man, with negative ova and parasite test and no eosinophilia. We also compared echography and computerizied tomograph as diagnostic tools for gallbladder ascariasis. The patient was managed conservatively, but he underwent cholecyctectomy later because of developing cholecystitis. CONCLUSION: Depending on this case, we suggest cholecyctectomy as an initial management of gallbladder ascariasis.

Gallstone-related abdominal cystic mass presenting 6 years after laparoscopic cholecystectomy: A case report.

INTRODUCTION: Although gallbladder perforation and gallstones spillage are common complications during laparoscopic cholecystectomy (LC), clinically significant complications resulting from stones left in the peritoneum are extremely uncommon. We report a rare case of spilled gallstones complication with a late and uncharacteristic presentation. PRESENTATION OF THE CASE: A 44-year-old Caucasian female presented with a complaint of a mass in the right upper quadrant associated with a cramping pain for the last 6 months. Her past surgical history included a laparoscopic cholecystectomy performed six years ago. Abdominal computed tomography demonstrated an intra-abdominal cystic mass. On open exploration, a cystic mass adhered to the abdominal wall was excised containing two gallstones. The patient tolerated the procedure well and had uneventful postoperative recovery. DISCUSSION: Although unretrieved gallstones are considered harmless, serious complications can occur early or late. The most frequent complication is the formation of abscesses in different locations. CONCLUSION: The diagnosis of gallstone abscess after years of LC is usually a diagnostic challenge. Obtaining a comprehensive past surgical history still plays an important role in the assessment of patients presenting with unusual findings.
