First Case

Two cases of Sarcophaga myiasis are reported from Montreal, Quebec. In the first case, larvae were passed in a bloody stool of a 5-year-old child and in the second, larvae were removed from a sore on the toe of a middle-aged man. The external morphology, cephalo-pharyngeal sclerites, prothoracic respiratory organs, and the posterior spiracular pit of the larvae ate described. Case I larvae agree with descriptions of S. haemorrhoidalis Fallén. Those from case II are probably S. crassipalpis Macquart. Both species are known to occur in Quebec. Probable modes of infection are discussed.

Mesenchymal Tumours

Cellular angiofibroma is a rare type of benign mesenchymal tumour that arises mostly in middle-aged women. It needs to be distinguished from other neoplasms and has a predilection for the vulvovaginal region. To our knowledge, this is the first case of a cervical cellular angiofibroma. A 34-year-old nulligravid woman was referred with a large mass bulging in the fornix posterior. Ultrasound scanning and MRI showed a large solid mass projecting in the pouch of Douglas. Laparoscopic surgical excision was performed. Histopathological examination showed a well-demarcated, unencapsulated tumour, consisting of short fascicles of spindle cells in-between thick-walled medium-sized vessels. On immunohistochemistry, there was strong reactivity with antibodies against CD34 and oestrogen receptor. Angiofibromas are benign mesenchymal tumours mostly occurring in middle-aged women. They can cause abnormal swelling and uterine bleeding and need to be distinguished from other (malignant) neoplasms.

Significant Disease

Enteric septicaemia of catfish was first detected in 1976 as an economically significant disease associated with commercial catfish production. Initially, Edwardsiella ictaluri was a host specific pathogen of catfish species but has also been reported from other hosts other than the catfish such as the zebrafish. E. ictaluri has not been isolated in humans hence it is not a zoonotic infection. There has been no previous report of isolation of this organism in humans. This was a case report of a 5 year old boy who presented with fever, vomiting, passage of bloody stool of 6 days and abdominal pain of a day duration. In the case of this 5 year old boy who presented with features of dysentery, blood culture using BACTEC™ grew E. ictaluri. E. ictaluri may be a pathogen which can infect humans just like another closely related species, Edwardsiella tarda. Although, E. ictaluri has not been reported in humans, could this be the first case? Non availability of diagnostic technique appropriate for its diagnosis may explain the rare incidence of the organism in humans, hence many cases would have been treated without isolating the organism.

Abstract Background: Currently, there is no available study about the occurrence of enterocolitis associated with the coronavirus disease 2019 (COVID-19) among adults. Case presentation: A 56-year-old man had lower abdominal pain, distension, diarrhea, and bloody stool. Moreover, the patient presented with fever and general fatigue. Laboratory examination did not reveal leukocytosis nor neutrophilia. However, the patient’s C-reactive protein level increased to 4.9 (normal range: 0.0–0.3) mg/dL. Both sputum and stool cultures had normal results. However, abdominal computed tomography (CT) scan revealed wall thickness mainly in the submucosal layer of the left part of the large intestine. Thus, real-time polymerase chain reaction test of throat swabs was performed for the diagnosis of COVID-19, and positive results were obtained. Conclusions: We report the first case of enterocolitis correlated to COVID-19, and the patient had positive abdominal CT scan findings. This imaging modality could be effective for the diagnosis of enterocolitis associated with COVID-19.

We report a fatal case of meningitis caused by Salmonella Enteritidis phage type 14b in a middle-aged man who had no history or findings to suggest he was immunocompromised. To our knowledge, this is the first reported case of Salmonella meningitis in an adult in Ireland, and the first case of meningitis in an adult caused by phage type 14b. This case was associated with a nationwide cluster of salmonellosis which is still under investigation at the time of writing.

Abstract Acute myocarditis following COVID-19 vaccination has been observed majorly following mRNA vaccines. Recently a single case of ChAdOx1 nCoV-19 vaccination induced myocarditis with an ischemic presentation has been reported. Here we report three cases of acute cardiac events following ChAdOx1 nCoV-19 vaccination, in an elderly female, a middle-aged male and a middle-aged female. The first case presented with an ischemic phenotype, the second with acute heart failure, and the third with cardiac symptoms and magnetic resonance imaging evidence of myocardial inflammation. The patients were all managed successfully with conservative treatment and showed symptomatic improvement within few weeks which was further corroborated by improved electrocardiographic and echocardiographic findings in the first two patients. The possibilities of molecular mimicry, autoimmunity and direct S-protein induced toxicity to the heart may need to be evaluated in the future to explain cardiac adverse events of COVID-19 vaccines.

Abstract Background Granulomatosis with polyangiitis (GPA) is a syndrome of refractory vasculitis involving the upper respiratory tract, lungs, kidneys, and systemic small and medium-sized arteries that affects all age groups. No pediatric case with a bloody pericardial effusion resulting in cardiac tamponade and co-existing hematochezia has been reported. Case presentation A 14-year-old boy was referred for evaluation of prolonged fever, chest pain, and intermittent hematochezia. Diagnostic imaging showed a prominent pericardial effusion. Immediately after admission, his systolic blood pressure decreased. Emergent pericardiocentesis resulted in aspiration of a massive amount of bloody pericardial fluid. This was diagnosed as cardiac tamponade because his blood pressure recovered immediately after the drainage. The patient had an elevated serine proteinase 3-anti-neutrophil cytoplasmic antibody (PR3-ANCA) level on serological examination. Head MRI showed thickening of nasal and sinusoidal mucosa and a cystic mass in the left sphenoid sinus. After ruling out malignancy based on the cytology of the effusion, chest MRI, and gallium scintigraphy, total colonoscopy showed multiple irregular-shaped aphthae from the right transverse colon to the cecum on the contralateral side of the mesenteric attachments. Biopsy specimens of aphthous lesions confirmed necrotizing granulomatous inflammation. A diagnosis of GPA was made based on these findings, and oral prednisolone (PSL) and azathioprine were started. The hematochezia disappeared rapidly, and no recurrence of pericardial effusion was seen after PSL tapering was completed. The PR3-ANCA level decreased into the normal range immediately after the initial therapy. Conclusions Pericarditis is a common cardiac complication of GPA, but there have been no reports of resultant cardiac tamponade. This is the first case of pediatric GPA with cardiac and gastrointestinal complications preceding the common symptoms such as respiratory or renal symptoms. A case of pediatric GPA with hematochezia is also extremely rare. In conclusion, serial measurement of ANCA levels is important in patients with persistent fever and bloody stool, such as in inflammatory bowel disease, to make the diagnosis of a vasculitic syndrome.

IntroductionHemoglobin crystals in the red blood cells were electronmicroscopically reported by Fawcett in the cat myocardium. In the human, Lessin revealed crystal-containing cells in the periphral blood of hemoglobin C disease patients. We found the hemoglobin crystals and its agglutination in the erythrocytes in the renal cortex of the human renal lithiasis, and these patients had no hematological abnormalities or other diseases out of the renal lithiasis. Hemoglobin crystals in the human erythrocytes were confirmed to be the first case in the kidney.Material and MethodsTen cases of the human renal biopsies were performed on the operations of the seven pyelolithotomies and three ureterolithotomies. The each specimens were primarily fixed in cacodylate buffered 3. 0% glutaraldehyde and post fixed in osmic acid, dehydrated in graded concentrations of ethanol, and then embedded in Epon 812. Ultrathin sections, cut on LKB microtome, were doubly stained with uranyl acetate and lead citrate.

Diffraction studies in polymeric and other beam sensitive materials may bring to mind the many experiments where diffracted intensity has been used as a measure of the electron dose required to destroy fine structure in the TEM. But this paper is concerned with a range of cases where the diffraction pattern itself contains the important information.In the first case, electron diffraction from paraffins, degraded polyethylene and polyethylene single crystals, all the samples are highly ordered, and their crystallographic structure is well known. The diffraction patterns fade on irradiation and may also change considerably in a-spacing, increasing the unit cell volume on irradiation. The effect is large and continuous far C94H190 paraffin and for PE, while for shorter chains to C 28H58 the change is less, levelling off at high dose, Fig.l. It is also found that the change in a-spacing increases at higher dose rates and at higher irradiation temperatures.

Small angle electron scattering (SAES) has been used to study structural features of up to several thousand angstroms in polymers, as well as in metals. SAES may be done either in (a) long camera mode by switching off the objective lens current or in (b) selected area diffraction mode. In the first case very high camera lengths (up to 7Ø meters on JEOL 1Ø ØCX) and high angular resolution can be obtained, while in the second case smaller camera lengths (approximately up to 3.6 meters on JEOL 1Ø ØCX) and lower angular resolution is obtainable. We conducted our SAES studies on JEOL 1ØØCX which can be switched to either mode with a push button as a standard feature.

Abstract This article was prompted by the submission of two challenging cases that exemplify the decision processes involved in using the AMA Guides to the Evaluation of Permanent Impairment (AMA Guides). In both cases, the physical examinations were normal with no evidence of illness behavior, but, based on their histories and clinical presentations, the patients reported credible symptoms attributable to specific significant injuries. The dilemma for evaluators was whether to adhere to the AMA Guides, as written, or to attempt to rate impairment in these rare cases. In the first case, the evaluating neurologist used alternative approaches to define impairment based on the presence of thoracic outlet syndrome and upper extremity pain, as if there were a nerve injury. An orthopedic surgeon who evaluated the case did not base impairment on pain and used the upper extremity chapters in the AMA Guides. The impairment ratings determined using either the nervous system or upper extremity chapters of the AMA Guides resulted in almost the same rating (9% vs 8% upper extremity impairment), and either value converted to 5% whole person permanent impairment. In the second case, the neurologist evaluated the individual for neuropathic pain (9% WPI), and the orthopedic surgeon rated the patient as Diagnosis-related estimates Cervical Category II for nonverifiable radicular pain (5% to 8% WPI).
