Prevalence, types, and characteristics of headache in Behcets disease without involvement of the central nervous system in the Syrian population: a case-cohort study.

Introduction: Oral ulcers, genital ulcers, and uveitis represent the typical trial of Behcet's disease (BD). It is well common on the Old Silk Road. The mucocutaneous lesions are the hallmark of BD, but neurological involvement is one of the severe symptoms. Headaches may be an early sign of BD neurological involvement. This study aims to investigate the headache prevalence and its types, and characteristics in a Syrian sample of BD patients. Methods: BD patients were clinically interviewed and examined to collect their information, symptoms, and signs. the International Study Group for Behcet's Disease diagnosis criteria was used to confirm the BD diagnosis. The International Classification of headaches was used when classifying the headaches. Results: One hundred twenty participants were included in the study. half of them were BD patients and the control group was also 60 participants. Among Syrian BD patients, 36.7% suffer from primary headaches and 36.7% suffer from secondary headaches. These findings were not significantly different between the BD patients and the healthy population. Our results showed that there was no statistically significant difference between the two groups. Conclusion: Headache should not be considered a predictor for neurological involvement among BD patients. Additional attention to BD patients or the specific treatment for headaches is not required and does not differ from the general population.

Antimicrobial Efficacy of Two Different Calcium Hydroxide Endodontic Dressings on the Eradication of Enterococcus faecalis in Single-Rooted Canals: An In Vitro Study.

INTRODUCTION: Bacterial pulp infections are considered the most common cause of endodontic treatment failure. Enterococcus faecalis was isolated from most cases of failure of endodontic treatment. Therefore, using the appropriate intra-canal dressing is essential for successful treatment. The improved formula used in calcium hydroxide PLUS points ensures more calcium hydroxide is released over a longer period and more space to release calcium hydration. This in vitro research aimed to evaluate the differences in the efficacy between Ca(OH)2 paste and PLUS points as an endodontic dressing in eradicating E. faecalis growth inside infected single-rooted canals. MATERIALS AND METHODS: Thirty mandibular first premolars with single canals were extracted for orthodontic reasons and were prepared after cutting their crowns to standardize the length of the roots to 17 mm, root preparation, and isolating E. faecalis. The infected sample root canals were contaminated with the prepared bacterial suspension, and the sample was incubated in the incubator under air conditions at 37°C for seven days, counting the bacteria colonies. Then, the bacterial units were counted before applying the drug, applying Ca(OH)2 paste in the first group and Ca(OH)2 PLUS points in the second group. The bacterial units were counted, and the number of bacteria was compared between the two substances applied to the samples, measuring the intracanal dressings' effectiveness. Wilcoxon signed-rank tests were used to detect significant differences.  Results: The results showed a statistically significant difference in the bacterial count of E. faecalis before and after applying the dressing of Ca(OH)2 paste from a mean of 11.89 to a mean of 3.18 (p=0.003) and no statistical difference in applying Ca(OH)2 PLUS points from mean 11.98 to mean 10.50 (p>0.05). CONCLUSION: Within the limits of the current in vitro study, the Ca(OH)2 paste cones were more effective than Ca(OH)2 PLUS points in eradicating E. faecalis growth inside the infected single-rooted canals.

Surgical challenges during open pancreaticoduodenectomy in a patient with situs inversus totalis: A rare case report and literature review.

Background: Situs inversus totalis is a rare congenital anomaly defined by a mirror-image of thoracic and abdominal viscera. Discrete cases of situs inversus totalis and its association with gastrointestinal tumors have been reported. Here we report the first case of pancreatic-head serous cystadenoma in patient with situs inversus totalis. Case presentation: A 68-year-old woman presented with an abdominal mass that appeared four months ago. She was otherwise asymptomatic and her physical examination was unremarkable. Chest X-ray revealed dextrocardia. CT scan confirmed situs inversus totalis with an irregular, clear border, heterogenous pancreatic-head mass measuring 11 cm. Laboratory studies were within the reference range and pancreatic tumor markers were normal. We performed an elective open pancreaticoduodenectomy followed by an end-to-side pancreaticojejunostomy, an end-to-side choledochojenunostomy, and a side-to-side gastrojejunostomy. The immediate postoperative course was uneventful, and she was discharged four days later without any complications. Four-month of follow-ups revealed no recurrent or relapsed disease. Discussion: Although the steps of the Whipple procedure are almost the same in SIT patients. The main differences during the operation in SIT patients are the anatomical variations and how the surgeon will cope with them to avoid any mistakes. Conclusion: The surgeons should improve their skills and gain control in both hands to easily adjust with the anatomic variations of situs inversus totalis and reduce the operation time and the associated risk of long operation time.

Hajdu Cheney syndrome; A novel NOTCH2 mutation in a Syrian child, and treatment with zolidronic acid: A case report and a literature review of treatments.

INTRODUCTION: Hajdu Cheney Syndrome (HCS) is a rare genetic disorder characterized by skeletal deformities such as acroosteolysis, osteoporosis, unique craniofacial features, and other systemic abnormalities. This syndrome is caused by NOTCH2 gene mutations, which cause an increase of osteoclast and osteoblast activity that leads to the increased bone resorption. Because of how rare the syndrome is and the vague onset of the symptoms, it can be challenging to make an early diagnosis. CASE PRESENTATION: We report a case of a female child with HCS who has a new NOTCH2 mutation sequence; (NM_024408.3:c.6463G > T) protein change (Glu2155*), and to our knowledge this is the first reported and diagnosed case in Syria. She presents with short stature, unique craniofacial features, scoliosis, kyphosis, and signs of osteoporosis, in addition to Patent Ductus Arteriosus. The patient was diagnosed with Hajdu Cheney Syndrome, and administered zolidronic acid, and she responded well to the treatment; showing signs of improved bone density and improvement in height, where her bone density improved from 0.23 to 0.31, and she gained 11 cm in height after the treatment. CONCLUSION: Due to the rarity of the syndrome, there is no established guideline for treatment yet. Based on the pathophysiology of the syndrome that causes increased bone resorption, treatment with the Bisphosphonates group has yielded positive outcomes. Furthermore, we compare different treatments in the literature with their results.

Antiphospholipid antibodies levels and potential effects on in-vitro fertilization in a large cohort of infertile Syrian women.

BACKGROUND: Obstetric morbidities represent a common hallmark manifestation of antiphospholipid syndrome (APS), with the recurrent loss of pregnancy as the main complication. The presence of antiphospholipid antibodies (APA) and its potential impact have not been established yet in infertile women seeking assisted reproduction technologies in Syria.This study aims to determine the prevalence of anticardiolipin antibodies (aCL) and lupus anticoagulation (LAC) and their association with age and the In vitro fertilization (IVF) outcomes in a large sample of Syrian women. MATERIALS AND METHODS: The electronic patients' records were screened and relevant data extraction was performed retrospectively. The study included 876 women who had IVF between January 2012 and January 2020 in a tertiary care hospital. RESULTS: The prevalence of APA among the included women was less than 1%. Only 5 patients had positive APA. No correlation was found between the APA levels and age. Additionally, the APA did not have an impact on neither the IVF outcomes nor the number of IVF cycles. CONCLUSION: the added value of APS antibodies' screening could be considered very modest when compared to its financial burden on patients since it has a very low prevalence in women having IVF.

Myxofibrosarcoma metastasis to the pterygopalatine fossa: A case report.

INTRODUCTION: Myxofibrosarcoma (MFS) is a rare subtype of a malignant soft tissue tumor that occurs mainly in adults, and peaks at the age of 70. It typically presents as a slow growing, painless mass in the proximal part of the extremities. It is characterized with a high recurrence rate and a low rate of distant metastases; the most common metastases site is the lungs, and in some extremely rare cases it was mentioned that there was metastases to the head and neck region. We here report the first case of a myxofibrosarcoma metastasized from the gluteal region to the pterygopalatine fossa, which is the first report in the literature of this rare metastatic spread of myxofibrosarcoma. CASE PRESENTATION: a 70 year-old male presented with diplopia and limited right eye movement. His medical history was significant for myxofibrosarcoma in his gluteus maximus. Magnetic resonance imaging showed a low signal mass in the pterygopalatine fossa. The tumor neither invaded the maxillary bone nor the maxillary sinus; the therapy plan was resection of the mass by partial maxillectomy followed by adjuvant radiotherapy. CONCLUSION: Metastasis to the pterygopalatine fossa should be considered in a patient with myxofibrosarcoma history presents with neuro-opthalmic symptoms. Partial maxillectomy in tumors that do not infiltrate into adjacent structures should be considered as a minimally invasive therapy.
