<b><i>Background:</i></b> Endoscopic ultrasound-guided ablation (EUS-A) therapy is a minimally invasive procedure for pancreatic-cystic tumors in patients with preoperative comorbidities or in patients who are not indicated for surgical resection. However, histopathologic characteristics of pancreatic cysts after ablation have not been well-elucidated. <b><i>Methods:</i></b> Here, we analyzed pathological findings of 12 surgically resected pancreatic cysts after EUS-A with ethanol and/or paclitaxel injection. <b><i>Results:</i></b> Mean patient age was 49.8 ± 13.6 years with a 0.3 male/female ratio. Clinical impression before EUS-A was predominantly mucinous cystic neoplasms. Mean cyst size before and after ablation therapy was similar (3.7 ± 1.0 cm vs. 3.4 ± 1.6 cm; <i>p</i> = 0.139). Median duration from EUS-A to surgical resection was 18 (range, 1–59) months. Mean percentage of the residual neoplastic lining epithelial cells were 23.1 ± 37.0%. Of the resected cysts, 8 cases (67%) showed no/minimal (&#x3c;5%) residual lining epithelia, while the remaining 4 cases (33%) showed a wide range of residual mucinous epithelia (20–90%). Ovarian-type stroma was noted in 5 cases (42%). Other histologic features included histiocytic aggregation (67%), stromal hyalinization (67%), diffuse egg shell-like calcification along the cystic wall (58%), and fat necrosis (8%). <b><i>Conclusion:</i></b> Above all, diffuse egg shell-like calcification along the pancreatic cystic walls with residual lining epithelia and/or ovarian-type stroma were characteristics of pancreatic cysts after EUS-A. Therefore, understanding these histologic features will be helpful for precise pathological diagnosis of pancreatic cystic tumor after EUS-A, even without knowing the patient’s history of EUS-A.

AbstractPancreatic cysts involve a wide spectrum of pathologies from post-inflammatory cysts to malignant neoplasms. Pancreatic pseudocysts, serous cystadenomas, mucinous cystadenomas, intraductal papillary mucinous neoplasms (IPMNs) and solid pseudopapillary tumors occur most frequently. Differential diagnosis involves the following imaging investigations: transabdominal ultrasonography (TUS), contrast enhanced ultrasonography (CEUS) and endoscopic ultrasonography (EUS), computed tomography (CT), magnetic resonance (MR) and magnetic resonance cholangiopancretography (MRCP), endoscopic retrograde cholangiopancretography (ERCP). The cyst fluid cytology is performed in difficult differential diagnosis between pseudocysts and benign and potentially malignant or malignant tumors. Most frequently, viscosity, amylase, CEA and CA 19-9 levels are determined. Imaging findings should be correlated with cytology. The management depends on the cyst type and size. Small asymptomatic pseudocysts, serous cystadenomas and branchduct IPMNs should be carefully observed, whereas symptomatic large or uncertain serous cystadenomas and cystadenocarcinomas, mucinous cystadenomas and cystadenocarcinomas, main-duct IPMNs and large branch-duct IPMNs with malignant features, serous and mucinous cystadenocarcinomas, and solid pseudopapillary tumors require surgery. Pseudocysts are usually drained. Percutaneous / EUS-guided or surgical cyst drainage can be performed. Complicated and uncertain pseudocysts and cystic tumors need surgical resection. The type of surgery depends on cyst location and size and includes proximal, central, distal, total pancreatectomies and enucleation.

Background: 1,2,3-triazoles are an important class of organic compounds and because of their aromatic stability, they are not easily reduced, oxidized or hydrolyzed in acidic and basic environments. Moreover, 1,2,3-triazole derivatives are known by their important biological activities and have drawn considerable attention due to their variety of properties. The synthesis of this nucleus, based on the click chemistry concept, through the 1,3-dipolar addition reaction between azides and alkynes is a well-known procedure. This reaction has a wide range of applications, especially on the development of new drugs. Methods: The most prominent eco-friendly methods for the synthesis of triazoles under microwave irradiation published in articles from 2012-2018 were reviewed. Results: In this review, we cover some of the recent eco-friendly CuAAC procedures for the click synthesis of 1,2,3-triazoles with remarks to new and easily recoverable catalysts, such as rhizobial cyclic β-1,2 glucan; WEB (water extract of banana); biosourced cyclosophoraose (CyS); egg shell powder (ESP); cyclodextrin (β- CD); fish bone powder; nanoparticle-based catalyst, among others. Conclusion: These eco-friendly procedures are a useful tool for the synthesis of 1,2,3-triazoles, providing many advantages on the synthesis of this class, such as shorter reaction times, easier work-up and higher yields when compared to classical procedures. Moreover, these methodologies can be applied to the industrial synthesis of drugs and to other areas.

Background: Pilomatricoma is a slow-growing, asymptomatic tumour originating from outer sheath cells of hair follicle. In this study, we describe the clinical presentation and histopathological features of pilomatricoma. Materials and Methods: This was a hospital based retrospective study carried out in all patients who were diagnosed as pilomatricoma over a period of January 2001 to December 2013. The study was done in department of pathology, Manipal Teaching Hospital, Nepal. Results: A total of 21 cases of pilomatricoma were reported with age range of 9-53 years (mean age 23.7) and male female ratio of 1:1.1. The most common site of occurrence was neck and preauricular region. The size of the tumour ranged from 0.3 to 4.7cm with a mean of 1.2cm. Multiple occurrences were seen in 3 patients and ossifying pilomarticoma was seen in 4 cases. Conclusion: Pilomatricoma is a benign skin neoplasm of hair follicle matrix cells. Calcification is a common finding while dystrophic ossification also can occur in the tumour. Histopathology gives the definite diagnosis as fine needle aspiration cytology and clinical impression may be misleading.

Pathologic Classification

Abstract Context.—Cystic lesions of the pancreas are being recognized with increasing frequency and have become a more common finding in clinical practice because of the widespread use of advanced imaging modalities and the sharp drop in the mortality rate of pancreatic surgery. Consequently, in the past 2 decades, the nature of many cystic tumors in this organ has been better characterized, and significant developments have taken place in the classification and in our understanding of pancreatic cystic lesions. Objective.—To provide an overview of the current concepts in classification, differential diagnosis, and clinical/biologic behavior of pancreatic cystic tumors. Data Sources.—The authors' personal experience, based on institutional and consultation materials, combined with an analysis of the literature. Conclusions.—In contrast to solid tumors, most of which are invasive ductal adenocarcinomas with dismal prognosis, cystic lesions of the pancreas are often either benign or low-grade indolent neoplasia. However, those that are mucinous, namely, intraductal papillary mucinous neoplasms and mucinous cystic neoplasms, constitute an important category because they have well-established malignant potential, representing an adenoma-carcinoma sequence. Those that are nonmucinous such as serous tumors, congenital cysts, lymphoepithelial cysts, and squamoid cyst of pancreatic ducts have no malignant potential. Only rare nonmucinous cystic tumors that occur as a result of degenerative/necrotic changes in otherwise solid neoplasia, such as cystic ductal adenocarcinomas, cystic pancreatic endocrine neoplasia, and solid-pseudopapillary neoplasm, are also malignant and have variable degrees of aggressiveness.

Cranio vertebral (CV) junction is one of the critical sites for surgery. It's anatomy, physiological aspects and pathological involvement varies in a wide range of margins. Common problems are developmental anomalies, traumatic involvement, inflammatory, infective and neoplastic lesion. Management of these problems varies a lot from each other. Aim of the article is to overview the pathologies in this area and to study presentations, investigations, surgical procedures and results of these pathologies. We prospectively analyzed 32 cases of Cranio-vertebral (CV) region surgery in the Department of Neurosurgery Dhaka Medical College Hospital and Mitford Hospital, Dhaka, from 2000 to 2008. In our series, male and female ratio was 7.2:1. Pathologies were atlanto- axial dislocation (AAD), Chiari malformation type –I, schwannoma, meningioma, hydatid cyst and tuberculosis. Common clinical findings were- neck pain, quadriparesis, quadriplegia, hand atrophy, autonomic dysfunction and hypertension. Various types of surgical procedures were done in this series according to the pathology. Death was in 01 case, neurological deterioration seen in one case, 2 cases were neurologically stable and 28 cases (87.5%) improved neurologically where one was non useful improvement (Frankel grade-C). Complete pre operative radiological study is a very important adjunct for a successful surgical result. Proper evaluation of patients with selection of appropriate surgical procedures along with safe surgical techniques are the necessary things for successful surgery in this area.

Background: Upper GI endoscopy is an established procedure for investigating a wide range of upper GI conditions especially inflammatory and malignant diseases of stomach and esophagus. A good correlation in diagnosis can be achieved by complementing endoscopic findings with histopathology of biopsy specimens. Methods: Both retrospective and prospective study of upper GI endoscopic biopsy was carried out at department of pathology, KIMS, Hubli during January 2016 to December 2018. Samples were received in 10% formalin; routine processing was followed with H & E staining. Special stain like Giemsa was done for detection of H. Pylori. 396 endoscopic mucosal biopsies were analyzed and evaluated. Result: Out of 396 cases, 250 cases were esophageal biopsies, 104 cases were gastric biopsies & 42 cases were duodenal biopsies. The male: female ratio was 1:9:1. The highest number of cases was seen between 61 to 70 years. Dyspepsia was the common symptom seen in 61.3%. The most common lesions encountered in the esophagus were carcinomas (67%) followed by esophagitis (16%). The commonly encountered gastric lesion was chronic gastritis in 54.8% with H. pylori gastritis being positive in 38.18%. Among the duodenal biopsies, non-neoplastic lesions were most common (59.5%) followed by neoplastic lesions (26%). Conclusion: Upper GI endoscopy is an effective and appropriate preliminary investigation to assess patients with dysphagia, dyspepsia, vomiting. Endoscopy without biopsy is incomplete and that the combination of methods offers a strong diagnostic tool for better patient care.

Rasa Shastra is the pharmaceutical branch of Ayurveda. As like any other medical system, success of Ayurvedic treatment also depends upon quality of medicine prescribed to the patient. The integral part of Rasa Shastra lies in the successful pharmaceutical process. Rasa oushadis are the potent Ayurvedic preparations mainly containing metals and minerals. These oushadis possess a wide range of therapeutic efficacy and are considered superior because of their qualities like small dose, quick action, palatability and longer shelf life. Mayaphaladi Churna is an important Rasa oushadi described in Rasa Tantra Sara Va Siddha Prayoga Sangraha- Part 2, Streerogadhikara indicated for the management of the diseases Swetapradara and Yonibramsha. The ingredients present in the ‘Mayaphaladi Churna’ are Kukkutanda twak bhasma (Egg Shell Ash), Shuddha Sphatika (Alum), Mayaphala Churna (Quercus Infectoria Oliv.), Amalaki Churna (Emblica Officinalis Gearth), Ashwagandha Churna (Withania Somnifera Linn.) and Sita Churna (Sugar Candy). The main pharmaceutical procedures involved in the preparation of Mayaphaladi Churna are Shodhana, Marana, Churna nirmana and preparation of Mayaphaladi Churna. The specific pharmaceutical blend of these contents can result in a more effective formulation. Therefore the present study has been planned to standardize the method of preparation of Mayaphaladi Churna according to the method explained in the classical literatures.

Summary: Pancreatic cysts have been detected ever more frequently in recent years due to the advanced and wider use of imaging methods. We find them on CT or MR also in asymptomatic patients who do not have a history of any pancreatic disease. Pancreatic cystic lesions represent a wide range of pathological changes from simple cysts through precancerous lesions to malignant cysts. Accurate dia­gnosis remains difficult despite the combination of clinical status evaluation, imaging findings, and bio­chemical and cytological examination. Molecular bio­logical examination of cyst aspirate obtained by endosonographic examination increases the detection rate of mucinous cysts (KRAS/GNAS/VHL) and cysts with a high risk of malignancy (KRAS/GNAS/p53/PIK3CA/PTEN/CDKN2A/SMAD4) and optimizes therapeutic approach. Larger prospective validation studies are necessary to make this costly and limited method a routine part of clinical practice. Key words: molecular bio­logy – neoplasia – pancreatic cysts

Background: Hysterectomy is the most common gynecological surgery done in the females worldwide as it provides definitive cure to a wide range of gynecological diseases, both benign and malignant. The indications to perform this major surgery should always be justified and the pathology should be proved histopathologically. Histopathological analysis and review is mandatory to evaluate the appropriateness of the hysterectomy.Methods: A retrospective, longitudinal study was conducted in the Department of Obstetrics and Gynecology, UMAID Hospital, Dr. S.N. M.C. Jodhpur (Raj.) during October 2014 to March 2015.Total 105 cases were studied during this period. The study included all women undergoing planned abdominal hysterectomy. Data was recorded on proformas, including demographic characteristics and clinical features. Hysterectomy specimens were saved in 10% formalin and sent to the Department of Pathology. Histopathology reports were analyzed and compared with the indications of surgery to draw various informative conclusions.Results: Of 105 cases, 55(52.38%) were in the age group of 41 – 50, which comprised the commonest age group undergoing the surgery. Maximum women (95%) those underwent hysterectomy were multiparous. Most common preoperatively clinical diagnosis was leiomyoma uterus which was diagnosed clinically and sonographically in 51(48.57%) cases. On Histopathological examination, the commonest pathology, similar to clinical impression, was found to be Leiomyoma at 50.48% (n = 53). Adenomyosis (21.90%) was detected as Second most common pathology. Histopathological confirmation of pre-operative diagnosis was 89% for malignancy, 96% for fibroids, 100% for adenomyosis, 100% for pelvic inflammatory disease.Conclusions: There was a high correlation when the clinical diagnosis was a fibroid, adenomyosis and ovarian mass. Every hysterectomy specimen should be subjected to histopathological examination because it is mandatory for conforming diagnosis and ensuring optimal management, in particular of malignant disease.
