RESUMO
Pancreaticopleural fistula (PPF) is a rare complication of chronic pancreatitis and pancreatic pseudocyst. It can present as recurrent pleural effusions and can be difficult to diagnose and treat. We present the case of a 37-year-old male with a history of chronic idiopathic pancreatitis complicated by a pseudocyst who came in with progressive dyspnea, cough, and pleuritic chest pain. The chest X-ray on presentation showed near-complete opacification of the left hemithorax, suggesting a large pleural effusion. Upon thoracentesis, black-bloody fluid was drained, and the pleural fluid analysis was consistent with an exudate with significantly elevated levels of amylase, lipase, and bilirubin. Cytology revealed abundant lipofuscin-laden macrophages, suggesting an intra-abdominal source of the accumulated fluid. A post-drainage CT of the chest showed the resolution of the pleural effusion and an interval decrease in the pancreatic pseudocyst size, indicating a fistulous connection to the pleural space. An endoscopic ultrasound (EUS) was performed with efforts to perform cystogastrostomy aspiration that was hindered by the interference of splenic vasculature obstructing the needle's path. The patient was transferred to another facility for definitive treatment with surgical pancreatectomy and auto islet cell transplant. This case underscores the importance of considering PPF as a possible diagnosis, especially in cases of recurrent pleural effusions and a history of pancreatitis and pancreatic pseudocyst. It also emphasizes the significance of EUS as the preferred modality for pseudocyst evaluation and its potential for minimally invasive treatment.
RESUMO
OBJECTIVE: To point out our experience and assess the efficacy and safety of real-time ultrasound-guided central internal jugular vein (IJV) catheterization in the treatment of hemodialysis patients. METHODS: This retrospective study comprised 150 patients with end-stage renal disease (ESRD) who had real-time ultrasonography (US)-guided IJV HD catheters placed in our hospital between March 2019 and March 2021. Patients were examined for their demographic data, etiology, site of catheter insertion, type (acute or chronic) of renal failure, technical success, operative time, number of needle punctures, and procedure-related complications. Patients who have had multiple catheter insertions, prior catheterization challenges, poor compliance, obesity, bony deformity, and coagulation disorders were considered at high-operative risk. RESULTS: All patients experienced technical success. In terms of patient clinical features, an insignificant difference was observed between the normal and high-risk groups (p-value > 0.05). Of the 150 catheters, 62 (41.3%) were placed in high-risk patients. The first-attempt success rate was 89.8% for the normal group and 72.5% for the high-risk group (p = 0.006). IJV cannulation took less time in the normal-risk group compared to the highrisk group (21.2 ± 0.09) minutes vs (35.4 ± 0.11) minutes, (p < 0.001). There were no serious complications. During the placing of the catheter in the internal jugular vein, four patients (6.4%) experienced arterial puncture in the high-risk group. Two participants in each group got a small neck hematoma. One patient developed a pneumothorax in the high-risk group, which was managed with an intercostal chest tube insertion. CONCLUSIONS: Even in the high-risk group, the real-time US-guided placement of a central catheter into the IJV is associated with a low complication rate and a high success rate. Even under US guidance, experience lowers complication rates. Real-time USguided is recommended to be used routinely during central venous catheter insertion.

PURPOSE: To report the result of percutaneous nephrolithotripsy (PCNL) via standard nephrostomy tract in a single training institution. The perioperative complications in relation to the comorbid state are particularly assessed. PATIENTS AND METHODS: A prospective interventional study between January 2019 to November 2022, included 210 patients scheduled for PCNL. The average age was 40.3 ± 11.8 years (range 18- 67 years). Patients were categorized into two groups. The first group comprised 146 cases (69 .5%) with no associated co-morbidities while the second group 64 (30.5%) had co-morbidities such as obesity in 4 cases (1.9%), hypertension (HTN) in 24 cases (11.4%) cases, diabetes mellitus (DM) in 17 (8.1%) cases, history of recurrent stone surgery in 11 (5.2%) cases and more than one in 8 cases (3.8%). Co-morbidities, stone burden, location of stone, time of surgery, stay in the hospital, further operations, and negative events were among the reported data. Complications and the stone-free rate were the main outcome indicators. RESULTS: Intraoperative complications were reported in 40 (18.8%) patients (18 group 1 and 22 group 2) during PCNL. Bleeding occurred in 22 (10.5%) patients (9 group 1 and 13 group 2), blood transfusions were needed in 4 (1.9%) (2 group 1 and 2 group 2), extravasation was observed in 11 patients (5.2%) (6 group 1 and 5 group 2) and cardiac arrhythmia in 3 (1.4%) (1 group 1 and 2 group 2) patients. Postoperative complications occurred in 61 patients (29%) (24 group 1 and 37 group 2) in the form of fever in 10 patients (4.8 %) (3 group 1 and 7 group 2) and prolonged leakage in 50 patients (23.8%) (21 group 1 and 29 group 2). One patient of group 2 died from postoperative sepsis. Extravasation and postoperative leakage were higher in diabetic patients than in non-diabetics. Stonefree rate was 60.5% (127 of 210). Clinically significant residual fragments (CSRFs) found in 70 cases (33.3%) (33 group 1 and 37 group 2). In 13 cases (6.2%) (5 group 1 and 8 group 2), clinically insignificant residual fragments (CIRFs) were found. In 8 (3 group 1 and 5 group 2) of the 13 cases, spontaneous stone passage was observed within 4-6 weeks of surgery. Residual stones in three cases (1 group 1 and 2 group 2) were asymptomatic and 4 mm or less, whereas stones increased in two cases of group 2. Among all factors studied, stone burden was significantly correlated to both intraoperative and postoperative complications. The occurrence of postoperative fever increased with large stone burden. CONCLUSIONS: PCNL is a therapeutic modality that is effective, feasible, and safe for a wide range of patients with concurrent medical issues. A steep curve is required to reduce intraoperative and postoperative complications.

OBJECTIVE: To evaluate safety and efficacy of Rezum therapy as a minimally invasive modality for management of benign prostatic hyperplasia in patients with prostate volume < 80cc and those with prostate volume > 80cc. METHODS: Between June 2020 and February 2023, A total of 98 patients diagnosed with BPH and managed by Rezum were included in this study. Patients were divided based on their prostate volume of either less than 80 cc or greater than 80 cc. We evaluated several parameters related to their condition, including prostate volume, post-voiding residual (PVR) before and after surgery, number of treatments received, maximum urine flow rate (Qmax) before and after surgery and mean follow- up periods. RESULTS: The mean age was 68 years (SD 11.2). The median prostatic volume was 62 cc (IQR 41, 17). A maximum of 9 treatments were administered. Six months was determined to be the average post-operative follow-up period (IQR: 3.5-7.2). The mean preoperative total PSA was 2.7 (IQR 1, 2), preoperative mean PVR was 79.8 cm3, preoperative mean Qmax was 8.2 ml/s (IQR 4.7-10.5), and median post-operative days until catheter removal was four days (IQR 3,1). Post-operative PVR was 24.7 cm3 (IQR 18.2, 29.4) and the mean post-operative Qmax was 18.3 ml/s (SD 6.3). Qmax levels significantly increased, by an average of 8.2 ml/s (SD 7.13) (p < 0.001). Similarly, a decrease of average PVR of 97.28 cm3 (SD 95.85) (p < 0.001) was detected, which is a substantial reduction. Between prostates less 80cc and those over 80cc, there were no appreciable differences in Qmax or PVR (p-values: 0.435 and 0.431, respectively). CONCLUSIONS: From our study, we conclude that Rezum water vapor thermal therapy, as a minimally invasive modality, is an effective and safe surgical option for management of benign prostatic hyperplasia of men with moderate to severe lower urinary tract symptoms (LUTS). This procedure has been shown to be effective in patients with varying larger prostate volumes.

Hepatitis B virus (HBV) is a widely prevalent liver infection that can cause acute or chronic hepatitis. Although current treatment modalities are highly effective in the suppression of viral levels, they cannot eliminate the virus or achieve definitive cure. This is a consequence of the complex nature of HBV-host interactions. Major challenges to achieving sustained viral suppression include the presence of a high viral burden from the HBV DNA and hepatitis B surface antigen (HBsAg), the presence of reservoirs for HBV replication and antigen production, and the HBV-impaired innate and adaptive immune response of the host. Those therapeutic methods include cell entry inhibitors, HBsAg inhibitors, gene editing approaches, immune-targeting therapies and direct inhibitors of covalently closed circular DNA (cccDNA). Novel approaches that target these key mechanisms are now being studied in preclinical and clinical phases. In this review article, we provide a comprehensive review on mechanisms by which HBV escapes elimination from current treatments, and highlight new agents to achieve a definitive HBV cure.
RESUMO
BACKGROUND/AIMS: The effectiveness of screening esophagogastroduodenoscopy (EGD) for refractory gastroesophageal reflux disease (GERD) symptoms alone has not been validated. METHODS: We performed an observational study of patients with refractory GERD who underwent EGD from 2013 to 2016 at a tertiary hospital. Among 928 patients with GERD, we excluded patients with other alarm features, other indications for EGD, history of gastroesophageal surgery, or EGD done for other diagnostic procedures, and identified 301 patients who underwent EGD solely for persistent reflux symptoms such as heartburn or regurgitation. RESULTS: Among 301 patients with refractory GERD, 81.4% of patients were taking PPIs. 49.8% of patients had completely normal EGD findings and 33.6% of patients had benign or incidental findings. Two patients (0.6%) had LA grade C or D esophagitis, and 16.3% of patients had irregular Z line or salmon-colored mucosa. 91.0% (122/134) who had a biopsy had normal or benign findings. 4.0% (12/301) of patients had biopsy-proven intestinal metaplasia which is similar to the previously known prevalence of intestinal metaplasia in patients without heartburn (5.6%) and none had dysplasia or malignancy. Male sex was associated with endoscopic intestinal metaplasia suspected lesions in multivariate analysis (OR: 1.96, 95% CI: 1.04-3.70, p = .036) but not biopsy-proven intestinal metaplasia. Elderly age, obesity, alcohol or cigarette consumption, PPI use, GERD duration >3-5 years did not predict endoscopically suspected or biopsy-proven intestinal metaplasia. Only 5% of patients had a pH-impedance study for refractory reflux symptoms. CONCLUSIONS: Most patients who underwent EGD for refractory GERD symptoms alone did not have pathological findings requiring a change in management. Screening EGD for patients only with persistent reflux symptoms should not be routinely recommended.

BACKGROUND: QT dispersion (QTd) is related to regional variations in myocardial repolarization. Our study aims to assess the value of QTd in prediction of myocardial ischemia and its severity during stress imaging. We enrolled one hundred patients having stable coronary artery disease (CAD) and fulfilling the "Appropriateness criteria for cardiac radionuclide imaging" (MPI). They were divided into group I including patients with MPI-detected ischemia (50 patients) and group II including patients with normal perfusion scan (50 patients). We excluded unstable CAD and all other causes affecting QTd. During isotope scan, ECGs were taken and QTd was calculated at rest and at maximum heart rate. RESULTS: QTd was significantly higher in the ischemic group both at rest and exercise (P = 0.000). QTd difference, the difference between QTd at rest and stress, was calculated. QTd difference was significantly lower in normal than in ischemic group (P = 0.003). There was a significant positive correlation between QTd difference and defect size (P = 0.04). CONCLUSION: QTd increases in ischemia and the QTd difference (between rest and stress) correlates positively with severity of ischemia. QTd and QTd difference could be used to improve the accuracy of stress imaging test.
RESUMO
BACKGROUND: Several factors might contribute to the delay to get cancer care including poor cancer awareness and having barriers to seeking help. This study described these barriers in Gaza and their association with recalling and recognizing cancer symptoms and risk factors. METHODS: A cross-sectional study was conducted in Gaza. Adult visitors (≥18 years) to the largest three governmental hospitals and adolescent students (15-17 years) from ten high schools were recruited. A translated-into-Arabic version of the validated Cancer Awareness Measure (CAM) was used to collect data in face-to-face interviews. It described demographic data, barriers to seek cancer care as well as recall and recognition of cancer symptoms and risk factors. Responses were compared between adults and adolescents as well as males and females. RESULTS: Of 3033 participants approached, 2886 completed the CAM (response rate= 95.2%). Among them, 1429 (49.5%) were adult (702 females; 49.1%) and 1457 (50.5%) were adolescent (781 females; 53.6%). The mean age± standard deviation (SD) of adult and adolescent participants was 33.7±11.7 years and 16.3±0.8 years, respectively. Emotional barriers were the most common barriers with 'feeling scared' as the most reported barrier (n=1512, 52.4%). Females and adolescents were more likely to report 'feeling scared' as a barrier than males and adults, respectively. Higher recall scores for cancer symptoms were associated with lower likelihood to report 'embarrassment', 'worry about wasting doctor's time' and 'difficulty arranging transport'. This was also seen for recalling risk factors, where 'embarrassment' and all practical barriers showed significant inverse associations with higher scores. In addition, greater recognition scores of cancer risk factors were inversely associated with reporting 'embarrassment' and 'feeling scared'. CONCLUSIONS: The most commonly perceived barriers to seeking cancer care were 'feeling scared' and 'feeling worried about what the doctor might find', followed by practical and service barriers. Females and adolescents were more likely to report 'fear' as a barrier to seek medical advice. Having a higher recall of cancer symptoms and risk factors was inversely associated with reporting most barriers. To improve patient outcome, early presentation can be facilitated by targeting barriers specific to population groups.

BACKGROUND: In low-income settings, cancer is often diagnosed in advanced stages due to late presentation. Good public awareness of cancer signs and symptoms has a positive impact on the time patients take before they present to healthcare professionals. Therefore, this study examined public knowledge of cancer signs and symptoms as well as risk factors in Gaza. METHODS: This was a cross-sectional study. Participants were recruited from adult visitors (≥18 years) to governmental hospitals covering all five governorates of Gaza, and adolescent students (15 to 17 years) from 10 high schools in corresponding locations. An Arabic version of the Cancer Awareness Measure (CAM) was completed in a face-to-face interview. It described demographic data and knowledge of: cancer prevalence, age-related risk, signs and symptoms as well as risk factors both in recall and recognition questions. RESULTS: Of 3033 participants invited, 2886 completed the CAM (response rate = 95.2%). Adult mean age ± standard deviation was 33.7 ± 11.7 years and that of adolescents was 16.3 ± 0.8 years. Half of the participants (n = 1457, 50.5%) were adolescent (781 females; 53.6%) and 1429 (49.5%) were adult (702 females; 49.1%). About two thirds (n = 1885) thought about cancer as unrelated to age. Only 196 participants (6.8%) identified colorectal cancer as the most common cancer among men. Awareness of cancer signs/symptoms was poor to fair, where 'lump' was most commonly recognized (n = 2227, 77.2%) and 'change of bowel habit' the least (n = 670, 23.2%). Only 217 participants (7.5%) had a good level of recognizing risk factors with 'smoking' being the most identified and 'eating less than five portions of fruits and vegetables a day' the least. There was a higher likelihood for adults to identify most cancer signs/symptoms and risk factors than adolescents, except for recalling 'unexplained pain', 'persistent cough/hoarseness', 'non-healing ulcer', 'smoking', and 'eating less than five portions of fruits and vegetables a day'. CONCLUSION: Public awareness of cancer signs/symptoms and risk factors needs to improve to facilitate early presentation and diagnosis in Gaza. Combining the delivery of public campaigns with tailored education to population groups, including the youth, may increase their knowledge and maintain its impact.

BACKGROUND: The effectiveness of the application of topical fluorides in prevention of erosive tooth wear has been an issue of controversy in the literature. The objective of this systematic review was to assess in situ studies investigating the effects of using topical fluorides on prevention of erosive tooth wear. MATERIAL AND METHODS: Two electronic databases PubMed/MEDLINE and Cochrane Central Register of Controlled Trials were searched. Eligibility criteria included in situ-controlled studies that assessed the effect of the erosive process without additional tooth brushing. The search involved English-written articles only. A total of 684 potentially relevant titles and abstracts were found after removal of duplicates, of which 22 full-text articles were selected. Seventeen studies were included in the qualitative synthesis of which 6 studies included in the meta-analysis. The following data were obtained for each study: authors, year of publication, country, study design, periods of study, duration, blinding, interventions (type/concentration/form), tooth substrate, location of the intraoral appliance, number of samples attached to each appliance, type of acidic media used for erosive challenge, duration of erosive challenge, subjects (number/age/sex), reported side effects -if any-, measuring device, amounts of tissue loss. RESULTS: The risk of bias of the included studies was assessed using the Cochrane Collaboration tool for assessing the risk of bias. A meta-analysis of the present study was performed using Comprehensive Meta-Analysis version 2.2.048 software. CONCLUSION: The use of oral hygiene products containing AmF/NaF/SnCl2 or NaF may be effective in the prevention of erosive tooth wear.
RESUMO
BACKGROUND: Acute left circumflex coronary artery (LCx) occlusion is not easily detected by the standard 12-lead electrocardiogram (ECG). METHODS: In 16 patients continuous ECG recording was performed during balloon occlusion. The treated lesions were divided into proximal and distal based on the location of the ischemic segments with respect to the left obtuse margin of the heart. RESULTS: Mean ΔST (=ST amplitude during inflation - pre-inflation ST) ≥0.5mm in both leads I and aVL predicted a proximal occlusion site with sensitivity of 62.5% (95% confidence interval [CI] 24.9-91.5%), specificity 100% (95% CI 63.1-100%), positive predictive value 100% (95% CI 47.8-100%), and negative predictive value 72.7% (95% CI 39-94%). In lead III, mean ΔST was +0.3mm in the distal and -0.2mm in the proximal group, respectively (p=0.036). CONCLUSIONS: ST elevation in leads I and aVL is associated with myocardial ischemia at or proximal to the left obtuse margin.

BACKGROUND: This study was conducted to compare and evaluate the effect of two different attachments (locator attachment and ball and socket [B&S] attachment) on implants and natural abutments supporting structures, in cases of limited inter-arch spaces in mandibular Kennedy Class I implant supported removable partial over dentures by measuring the bone height changes through the cone beam radiographic technology. MATERIALS AND METHODS: Two implants were positioned in the first or second molar area following the two-stage surgical protocol. Two equal groups were divided ten for each: Group I: Sides were the placed implants restored by the locator attachment. Group II: The other sides, implants were restored by B&S attachment. Evaluation of the implants and main abutments supporting structures of each group was done at the time of removable partial over denture insertion, 6, 12 and 18 months by measuring the bone height changes using cone beam computed tomography. RESULTS: Implants with locator attachment showed marginal bone height better effects on implants and main abutments supporting structures. CONCLUSION: Implants restored by locator attachment shows better effects on bone of both main natural abutments and implant than those restored with ball and socket.
RESUMO
BACKGROUND: This study evaluated and compared the bacteriological effect of two-piece implants and one-piece implants in complete overdenture cases on supporting structures. MATERIALS AND METHODS: Ten male completely edentulous patients were selected and randomly divided into two equal groups according to the implant design and surgical technique for this study; Group 1: Patients were rehabilitated with complete mandibular overdenture supported by two-piece implants one on each side of the lower arch following two-stage surgical technique and Group 2: Patients were rehabilitated with complete mandibular overdenture supported by one-piece implants one on each side. Evaluation was made at the time of insertion, 6, 12, and 18 months after overdenture insertion, by measuring bacteriological changes around implants abutments. RESULTS: Complete overdenture supported by one-piece implants showed better effect on the bacteriological changes as compared to that supported by two-piece implants. CONCLUSION: Complete overdenture supported by one-piece implants one on each side of the lower arch showed better effect on the bacteriological changes than using the same prosthesis supported by two-piece implants.
RESUMO
A 59-year-old female with structurally normal heart was admitted to our hospital for treatment of highly symptomatic, drug refractory atrial premature beats (APB). ECG revealed atrial parasystolic trigeminy. The arrhythmogenic focus was mapped and ablated using magnetic remote navigation and 3D electroanatomical mapping system. To our knowledge, this is the first report on successful ablation of frequent APBs in the non-coronary aortic cusp.
RESUMO
Meningiomas of the skin are rare tumors that can pose considerable diagnostic challenges to the pathologist. This study presents a case of primary cutaneous meningioma in a newly born baby girl that presents with a subcutaneous nodule on the left posterior occipital scalp. A Magnetic Resonance Imaging examination failed to detect any communication between the tumor site and the meninges. The mass was excised and intra -operatively, there was no evidence of connection between the tumor and the underlying tissues. Microscopically, the tumor was composed of banal looking, mitotically inactive spindle-shaped cells with a whorled configuration. Some cells were concentrically arranged around blood vessels. Immunohistochemical studies were positive for epithelial membrane antigen and vimentin. Immunostains for cytokeratin, S-100 protein, vascular (CD34 and CD31) and muscle markers (Desmin and smooth muscle actin) were negative. The diagnosis of cutaneous meningioma was established. A review of literature was presented.
