Pathological conditions of trachea and lungs of slaughtered buffaloes were investigated in the present study. A total of 80 slaughtered buffaloes were examined individually and trachea (80) and lungs (80) were collected for histopathology from the slaughterhouses of Barisal sadar, Barisal, Bangladesh, during the period from July 2006 to March 2007. Among them 9 trachea and 30 lungs were found to be apparently abnormal in naked eye. Grossly, tracheal and lungs lesions were 11.25% and 37.5% in buffaloes, respectively. The gross tracheal lesions were petechial haemorrhages on the mucosa of trachea and lungs lesions were haemorrhage and congestion in lungs (16.25%), hard nodule formation (7.5%), cyst in lungs (6.25%), emphysematous lung (5%) and thickened pleura (2.5%). In histopathology, congestion (5%) and mild tracheitis (8.75%) were recorded as tracheal lesions. Histopathological examination of lungs noticed a number of conditions or lesions such as chronic interstitial pneumonia (3.75%), edema fluid (3.75%), broncho-pneumonia (3.75%), bronchitis (2.5%), bronchiolitis (2.5%), pneumonia-congested stage (8.75%), hydatid cyst (6.25%), fibrinous pneumonia (3.75%), healed nodule (7.5%), purulent broncho-pneumonia (1.25%), fibrino-purulent pneumonia (1.25%), subacute fibrinous pneumonia (1.25%), pulmonary adenomatosis (1.25%), pleuritis (2.5%) and hemosiderosis (3.75%). For morphological descriptions, the lesions were categorized into various types; however a single section showed intermixed of various lesions.

Cardiac Myxomas

Cardiac myxomas are the most common primary cardiac tumors and are typically attached to the interatrial septum. Left ventricular myxomas are exceedingly rare and presentation in children is all the more uncommon. We report a case of left ventricular myxoma with very atypical cystic appearance raising an initial suspicion of a hydatid cyst. Subsequently, cardiac magnetic resonance imaging was done, which ruled out the diagnosis of hydatid cyst. Complete surgical excision was done through transaortic and transmitral route. Histopathological examination revealed it to be a cardiac myxoma with vascular proliferation, which on echocardiography had appeared as a polycystic lesion. This is a very unusual histopathological presentation of cardiac myxoma.

Primary Hydatid Cyst

Hydatid cyst caused byEchinococcus granulosusdemonstrates an endemic infection in several countries such as Middle Eastern countries. Liver is the most frequently involved organ, followed by the lung. The case we present is solitary primary localization of cyst in abdominal wall which is extremely rare. A 57-year-old woman presented with an abdominal wall lesion in umbilical area that had been evolving for about 2 years with recent complaint of pain and discomfort. We detected a midline abdominal mass12⁎13centimeters in diameter which was bulged out in umbilicus. Preoperative clinical diagnosis of incarcerated umbilical hernia was made due to its physical examination while surgical exploration disproved the primary diagnosis and we found cystic mass adherent to superficial fascia without any communication to peritoneal space. The cyst was excised completely without any injury or perforation of containing capsule. The diagnosis of hydatid cyst was confirmed by histopathological examination of specimen. The retrograde evaluation showed no involvement of other organs. The patient was followed for two years and no recurrence of hydatid disease has been observed. Hydatid cyst should be considered as a differential diagnosis of abdominal wall and umbilical lesions especially in endemic regions.

Accurate clinical diagnosis of pneumonia, the leading cause of mortality in small ruminants, is difficult and usually requires postmortem examination of the lungs. An active abattoir survey was conducted between November 2017 and April 2018 to estimate the prevalence and characterize the gross and histopathological lesions of pneumonic lungs in 864 clinically healthy young small ruminants (490 sheep and 374 goats aged 1.5 to 3 years) raised for meat in different parts of the country and slaughtered at Elfora Bishoftu export abattoir, Ethiopia. Out of the total lungs examined grossly, pneumonic lesions were found in 158 (18.29%) lungs. On histopathological examination of the lungs with gross pneumonic lesion, however, typical pneumonic lesions were diagnosed in 148 (17.13%) lungs only. No significant (p>0.05) difference was noted in the prevalence of pneumonia between sheep (17.14%) and goats (17.11%) in histopathological examination. Based on the predominant histopathological findings, the pneumonic lesions were characterized as interstitial pneumonia (41.9%), acute suppurative bronchopneumonia (25.7%), acute fibrinous bronchopneumonia (24.3%), chronic bronchopneumonia (6.1%), aspiration pneumonia (4.7%), bronchointerstitial pneumonia (3.4%), and ovine pulmonary adenomatosis (3.4%). The study further showed the spread of ovine pulmonary adenomatosis and ovine progressive pneumonia (Maedi) from the central highlands to areas that were previously free from these diseases. Due to its better diagnostic capacity, histopathology should be employed routinely as an ancillary test in the major abattoirs and regional veterinary laboratories to generate additional epidemiological data for a better disease control and prevention measures. Further studies are also recommended to identify the etiological agents of pneumonia in sheep and goats and thereby to formulate feasible and cost-effective interventions.

 Primary pelvic hydatid cyst disease is a zoonotic parasitic disease most frequently caused by Echinococcus granulosus or Echinococcus multilocularis. Primary pelvic hydatid cyst is a rare entity. A 39-year-old, para 3 living 3 presented to casualty with acute pain abdomen and a suprapubic mass. Patient gave history of acute lower abdominal pain since 4 days associated with vomiting. On examination, a palpable mass around 18 weeks size, firm to hard in consistency with ill-defined margins and restricted mobility and suprapubic tenderness. Lower limit could not be reached, extending from right iliac fossa to midline. Per vaginum findings suggestive of mass deviated to right side with fullness in right fornix. No cervical motion tenderness. The pre-operative tumor marker levels were as follows: CA125=12.44 U/mL (normal=0-35), CEA=0.09 ng/mL (normal=0-2.5). CA19.9=16.79 U/mL (normal=1.2-30). Erythrocyte sedimentation rate (ESR) was found to be 82 mm in the first hour. Transabdominal ultrasound suggestive of adnexal mass? ovarian with moderate ascites. Urinary bladder seen separately. Contrast enhanced computed topography (CECT) suggestive of complicated right para-ovarian /ovarian cystic mass like cystadenoma. Exploratory laparotomy was done and specimen (uterus, cervix, omental biopsy and peritoneal washings) was sent for Histopathological report. Histopathological examination of the haematoxylin and eosin-stained section revealed ruptured brood capsule releasing daughter cyst. Post-operative period was uneventful. Patient received full course of anti-helminthic treatment.

Hydatid disease remains a serious health problem in Mediterranean countries. Living in a rural area is an important risk factor for the disease. Hydatid cysts are usually located in the liver, lungs and brain. Mediastinal hydatid disease is very rare and has been noted only anecdotally in the literature. The present article reports a case of a mediastinal hydatid cyst rupturing into the pleural cavity, which was associated with pneumothorax of the same side. The patient’s previous chest x-rays (posteroanterior and left lateral views) showed a well-defined mediastinal mass on the left side, and contrast-enhanced computed tomography of the thorax (taken a few days after the chest x-ray) showed multiple round-to-oval soft tissue opacities with partial collapse of the left lung. An indirect hemagglutination test for echinococcus was positive. Even after two weeks of intercostal tube drainage, the patient’s condition did not improve. During thoracotomy, multiple daughter cysts were found in the pleural cavity, and the diagnosis of a hydatid cyst was confirmed after histopathological examination.

Abstract Species of Hystrichis are parasite nematodes of the digestive tract of aquatic birds in South America, Europe and Asia. In Brazil, Hystrichis acanthocephalicus has been reported in Phimosus infuscatus. There are few data on the morphometry of this species and there are no reports on pathological conditions that it causes. Therefore, the purpose of this study was to report morphometric data from H. acanthocephalicus and describe the pathological effects of this parasite on the Phimosus infuscatus proventriculus. Thirty gastrointestinal tracts of P. infuscatus were examined to search for nematodes and H. acanthocephalicus occurred in 83% of hosts. Were measured the total length and body width of males and females, and of their respective cuticular spines, esophagus, spicules and eggs, and the internal and external diameter of copulatory bursa. Histopathological examination revealed parasitic structures in the proventriculus from the lumen (anterior end) to the outer layers of the organ (intermediate and posterior parts), in which we observed inflammatory reaction with infiltration of heterophils, hemorrhage and hemosiderin. The results of this study of histopathology, morphometry and parasitological indices are the first ones reported to H. acanthocephalicus and should contribute to the identification and recognition in cases of outbreaks in the Neotropical region.

The aim of this study was to investigate the compatibility of a fascia lata autograft for urinary bladder tissue defect, to evaluate the biomechanical, radiographical, macroscopical, biochemical, and histopathological test findings, and early and late complications of the surgical processes in rabbits. Thirty two adult healthy New Zealand rabbits were randomly allocated to 4 different groups of 8 animals. A 2 × 2 cm urinary bladder defect was repaired by the same size of fascia lata in experimental groups (Group 1, 2, 3). Rabbits in Group 1, 2 and 3 were euthanized at the end of the 4th, 8thand 12thweek after surgeries, respectively. No surgical procedure was carried out for the urinary bladder of the rabbits in the control group, but their urinary bladders were used for biomechanical tests and the values compared with those of Group 1, 2 and 3. Histopathological examination of the grafted area was performed. The grafted area was consistent with that of the tissue of urinary bladder. No significant difference was found between the urinary bladder and the grafted area. No differences in biomechanical tests were recorded between grafted and ungrafted urinary bladders. Histopathologically, fascia lata turned into a normal urinary bladder tissue. Therefore, a fascia lata autograft can be succesfully used in urinary bladder defects. Fascia lata grafts can be used successfully in pathological conditions of the urinary bladder that require a new tissue.

Interstitial pneumonia is a heterogeneous disease with a progressive course and poor prognosis, at times even worse than those in the main cancer types. Histopathological examination is crucial for its diagnosis and estimation of prognosis. However, the evaluation strongly depends on the experience of pathologists, and the reproducibility of diagnosis is low. Herein, we propose MIXTURE (huMan-In-the-loop eXplainable artificial intelligence Through the Use of REcurrent training), a method to develop deep learning models for extracting pathologically significant findings based on an expert pathologist's perspective with a small annotation effort. The procedure of MIXTURE consists of three steps as follows. First, we created feature extractors for tiles from whole slide images using self-supervised learning. The similar looking tiles were clustered based on the output features and then pathologists integrated the pathologically synonymous clusters. Using the integrated clusters as labeled data, deep learning models to classify the tiles into pathological findings were created by transfer-learning the feature extractors. We developed three models for different magnifications. Using these extracted findings, our model was able to predict the diagnosis of usual interstitial pneumonia, a finding suggestive of progressive disease, with high accuracy (AUC 0.90). This high accuracy could not be achieved without the integration of findings by pathologists. The patients predicted as UIP had significantly poorer prognosis (five-year overall survival [OS]: 55.4% than those predicted as non-UIP (OS: 95.2%). The Cox proportional hazards model for each microscopic finding and prognosis pointed out dense fibrosis, fibroblastic foci, elastosis, and lymphocyte aggregation as independent risk factors. We suggest that MIXTURE may serve as a model approach to different diseases evaluated by medical imaging, including pathology and radiology, and be the prototype for artificial intelligence that can collaborate with humans.
