Analysis of Helicobacter pylori gastritis according to Sydney classification.
No full textIntroduction: Since H. Pylori has been isolated in stomach and duodenum, there were individual methodologies to explain the grading according to colonization and density of microorganism. In 1990 Sydney system of classification was proposed at the 9th world congress of gastroenterology in Sydney Australia, based on topo-graphical, morphological and etiological findings. This classification revised in 1994 and updated by experts in Houston Texas. H. Pylori is major cause of chronic gastri-tis results in gastric and peptic ulcer. It also causes MALT lymphoma and malignan-cy. For histopathological examination four specimens, two from antrum and two from corpus are recommended.Objective: To evaluate the Sydney system of classification and grading for H. Pylori in local population.Methodology: 287 cases of biopsies received at the department of pathology Mu-hammad Medical College, Mirpurkhas Sindh Pakistan, during the period of January 2017 to December 2018 were revised. Sections stained with Hematoxylin and Eosin; Alcian blue and periodic acid Schiff to define H. Pylori and associated pathological changes. The microscopical findings classified according to upgraded Sydney pattern.Results: Out of 287 cases of gastric biopsies 23 (8.0%) were positive for H. Pylori. chronic inflammation present in 168 (58.5%). Neutrophilic activity found in 58 (18.1%). Atrophy without metaplasia observed in 31 (10.8%). Intestinal metaplasia present in 1 (0.3%) cases.Conclusion: Sydney system of grading is best to evaluate chronic gastritis and relia-ble indicator of H. Pylori microorganism.

Therapeutic efficacy of Dornier MPL 9000 for prevesical calculi as judged by efficiency quotient
No full textPurpose: To study the efficacy and safety of the Dornier MPL 9000 lithotripter in the treatment of prevesical calculi using real-time ultrasound monitoring and to see if efficacy is adequately judged by the efficiency quotient (EQ). Patients and Methods: Seventy-six patients underwent ultrasound-guided extracorporeal shockwave lithotripsy (SWL) for prevesical calculi over a period of 43 months. Their age ranged from 8 to 68 (mean 37.6) years, and the male:female ratio was 2.6:1. The size of the stones, measured in two dimensions, ranged from 4 to 25 mm (mean 9.3 mm) and 2 to 15 mm (mean 6.0 mm). No general or regional anesthesia or ureteral stents were used, and all patients were treated in the prone position. The EQ was calculated using the formula: Stone free (%) x 100/(100 + retreatment rate (%) + auxiliary procedures (%).Results: Seventy patients were stone free in a mean time of 15 +/- 14.11 days. The average number of shockwaves used was 2,831 +/- 1,612, and the average number of sessions per patient was 1.7. About 92% of the patients were rendered stone free using in situ SWL alone. No major complication was encountered, and none of the patients required an inpatient stay after SWL. The EQ was 65. Five patients with failed SWL subsequently were rendered stone free, four with salvage ureteroscopy and pneumatic lithotripsy and one with cystolitholapaxy for a symptomatic fragment in the bladder. One patient was lost to follow-up.Conclusion: In situ SWL is a safe and effective treatment for prevesical calculi. It should be used as a first-line treatment for most such stones. Efficiency can be assessed objectively by the EQ
Acute urinary retention: A primary manifestation of chronic lymphocytic leukemia and organ confined prostate cancer
No full textClinical impact of incidental diagnosis of disease on non-contrast-enhanced helical CT for acute ureteral colic
No full textThe role of un enhanced helical CT (UHCT) in the evaluation of acute flank pain suggestive of urinary tract calculi is increasingly appreciated in the last few years. Recent studies have identified the advantages of UHCT in recognizing alternative findings within or outside the urinary tract. These incidental diagnoses on UHCT alter a patient\u27s management and demonstrate the pivotal role of UHCT in rapidly triaging these patients for appropriate management. Clinical impact of incidental diagnoses is maximal in identifying alternate emergent conditions mimicking reno-ureteric colic and in identifying malignancies at an early stage when they are potentially curable

No full textCandidal infections as a cause of recurrent uretero-ileal anastomotic dehiscence
No full textFungal infections are common in immunocompromised patients. The presentation is often subtle and therefore treatment is delayed. Uretero-ileal anastomotic dehiscence due to candidal infection has never been reported before. This case represents an uncommon but potentially life-threatening complication in reconstructive surgery; that is, anastomotic dehiscence due to a unique etiology
Adaptive Swin Transformer V2-Tiny Based Model for Classification of Bacteria, Fungus, Virus, and Healthy Fruit and Leaf Images
No full textThe classification of fruits and leaves affected by bacteria, viruses, and fungi has made significant progress in the fields of artificial intelligence and image processing. However, most methods focus on particular categories of fruit and leaf diseases, but not on both fruit and leaf diseases caused by bacteria, viruses, and fungi. This study aimed to develop a model for the classification of the initial, intermediate, and final stages of bacterial, viral, and fungal diseases, irrespective of fruit and leaf types. To achieve this goal, inspired by the accomplishments of the Swin Transformer, the Swin Transformer V2-Tiny was explored for the classification of 10 classes, which included healthy and three stages of bacteria, virus, and fungus images of fruits and leaves. The stages of Swin Transformer V2-Tiny divide the image into patches, namely, linear projection, Window Multi-Head Self-Attention (W-MSA), and Shifted Window Multi-Head Self-Attention (SW-MSA) for local and global features, which were adapted to perform the plant disease classification. Experiments on authors’ curated and standard datasets and a comparative study with recent methods demonstrate effective classification and superiority over existing methods. To the best of our knowledge, this is the first study on the classification of fruit and leaf pathogens caused by bacteria, viruses, and fungi based on their development stages. The proposed model achieved an average classification rate of 91.04% on fruit datasets and 94.07% on leaf datasets, outperforming recent benchmark methods. It also demonstrated strong generalization on unseen public datasets with over 93% accuracy.

No full textThis research is a study and investigation of a manuscript on the biography, beauty and morals of our Noble Prophet Muhammad bin Abdullah, may God’s prayers and peace be upon him, whose name is (Manahil al-Safa fi Dhat al-Mustafa, may God’s prayers and peace be upon him) by Abu al-Abbas Ahmad ibn Abd al-Hayy al-Halabi al-Fassi (d. 1120 AH), which is a manuscript of nine papers, in which he spoke. The author before describing the beauty of the Prophet, may God’s prayers and peace be upon him, with an introduction to the meaning of beauty and majesty in the language, and he mentioned benefits and warnings in it, then he described the beauty of God Almighty, and after that he mentioned the images of the Prophet Muhammad, may God’s prayers and peace be upon him, physical and moral beauty that God Almighty preferred and distinguished him from other prophets And other people and made it a reason to win the hearts of many people and their entry into the religion of God Almighty. In his words, the author of the manuscript cited verses from the Noble Qur’an, hadiths from the Sunnah, and verses from Arabic poetry, in addition to the rhetorical and jurisprudential sayings of scholars, through which he clarifies the intended meaning of the images of beauty mentioned or mentioned by scholars who preceded him, relying on various sources, including: Books Interpretation of the Noble Qur’an, books of the Prophet’s biography, books of the noble Prophet’s hadith, books and dictionaries of the Arabic language, books of jurisprudence, books of mysticism and faith
