Parasitic diseases of the eye are a widespread and poorly studied problem. This article is intended to systematize the possible mechanisms of infection and to determine the features of the clinical course and treatment of an ocular dirofilariasis. For this purpose, case reports and research data from medical professionals from Europe and Asia are presented. Conclusions were drawn regarding the dependence of the clinical course on the host  – parasite interaction and immune response and that the only applicable method of treatment in all the cases considered was surgical intervention.

Struma Ovarii

Struma ovarii is a rare variant of the mature ovarian teratoma composed of more than 50% thyroid tissue. Thyroid type carcinoma can occur in 5% of struma ovarii. Given the rarity of this pathology, as well as the different clinical course, approaches to the treatment of this disease are controversial. The proposed approaches to treatment vary from ovarian resection to total hysterectomy with bilateral salpingo-oophorectomy and adjuvant therapy. We present here 6 case reports of thyroid type carcinoma in struma ovarii and outcome of patients treated in our clinic. All patients had pelvic surgery of different extent, followed by thyroidectomy and radioiodine therapy. The incidence of metastasis is 67% (4/6), 2 - intraperitoneal metas-tases, 2 - bone metastases. Among patients with metastases, 2 have reached a complete response, one with a good response continues treatment, one had progression. The follow-up period is 1 to 15 years (median 4 years). One patient with follicular carcinoma died of progression 8 years after diagnosis. The remaining patients are alive.

AbstractThe objective of the study was to identify distinct patterns in inflammatory immune responses of COVID-19 patients and to investigate their association with clinical course and outcome. Data from hospitalized COVID-19 patients were retrieved from electronic medical record. Supervised k-means clustering of serial C-reactive protein levels (CRP), absolute neutrophil counts (ANC), and absolute lymphocyte counts (ALC) was used to assign immune responses to one of three groups. Then, relationships between patterns of inflammatory responses and clinical course and outcome of COVID-19 were assessed in a discovery and validation cohort. Unbiased clustering analysis grouped 105 patients of a discovery cohort into three distinct clusters. Cluster 1 (hyper-inflammatory immune response) was characterized by high CRP levels, high ANC, and low ALC, whereas Cluster 3 (hypo-inflammatory immune response) was associated with low CRP levels and normal ANC and ALC. Cluster 2 showed an intermediate pattern. All patients in Cluster 1 required oxygen support whilst 61% patients in Cluster 2 and no patient in Cluster 3 required supplementary oxygen. Two (13.3%) patients in Cluster 1 died, whereas no patient in Clusters 2 and 3 died. The results were confirmed in an independent validation cohort of 116 patients. We identified three different patterns of inflammatory immune response to COVID-19. Hyper-inflammatory immune responses with elevated CRP, neutrophilia, and lymphopenia are associated with a severe disease and a worse outcome. Therefore, targeting the hyper-inflammatory response might improve the clinical outcome of COVID-19.

Promising Therapeutic Agent

Aneurysmal bone cysts (ABC) are benign bone tumors, which are highly vascularized. The main course of treatment is curettage followed by bone grafting or cement insertion. Still recurrence remains a main problem for patients. Denosumab is a monoclonal antibody, which acts as an inhibitor of the RANK/RANKL pathway, diminishing bone turnover. Recent case reports have shown that Denosumab can be a promising therapeutic agent for people suffering from therapy-resistant ABC. We report the case of a 35-year-old female patient presenting with a pronounced ABC of the pelvis. Since the tumor was inoperable, Denosumab was administered, leading to a significant shrinkage of the lesion, which allowed surgical intervention. Upon recurrence, Denosumab was restarted putting the patient once more into remission. Follow-up was four years overall with a clinical and radiological stable disease for fifteen months after final discontinuation of the monoclonal antibody. Therefore, our case further underlines the potential of Denosumab in the treatment of ABC.

SUMMARYThe frontal and sub-parietal glands of the pentastomidReighardia sternaeelaborate lamellate secretion which is poured on to the cuticle. The entire surface of the cuticle, including the mouth, hook pits and reproductive apertures, is coated with secretion. Electron microscope studies indicate that the glands are continuously active, which implies a turnover of surface membranes. The postulated function of these membranes is to protect certain vital areas of the host–parasite interface, notably the pores of ion-transporting cells, from the host immune response. The available evidence suggests that pentastomids do evoke a strong immune response but since most are long-lived they must circumvent it. We believe the surface membrane system to be instrumental in this. Studies on another pentastomid,Porocephalus crotaliin rats have shown that an immune response stimulated by a primary infection will kill subsequent infections and that the surface membranes are strongly immunogenic. Obvious parallels between this situation and that of schistosome infections in mammals are discussed. An alternative explanation of concomitant immunity is proposed.

Objective: We report a case of self inserted needle into the left ventricle of the heart and a description of our surgical intervention in a psychiatric patient without decision-making capacity. We discuss issues regarding obtaining consent in this patient with a sub-acute presentation, report our operative approach, and summarize a treatment approach based on a review of current literature. Methods: A PubMed search using terms “needle, “heart”, “insertion”, “intracardiac foreign object”, yielded 69 relevant papers. 67 of these were case reports yielding 72 individual cases. Age, gender, cause of the needle entry (Accidental Plus (A+), Intravenous Drug User [IVDU], Self-inflicted (SI)), type of needle, location in heart, neuropsychiatric history, treatment, and outcome were documented. Results: Within the SI category, there were a total of 28 cases, 89.3% had a neuropsychiatric history whereas only there were only 2 such patients in both the IVDU and A+ group. The location of the needle in the heart in all 72 cases was as follows: right ventricle 40.3%, other 20.8%, left ventricle 19.4 %, ventricle and interventricular septum 16.7% and the right and left atrium were each 1.4 %. In all three groups (n=72), 77.8% of patients underwent surgery, with 92.9% having a stable outcome. Conclusion: Our case and review demonstrates that management of such cases, particularly when active mental health issues are present, requires a case-by-case evaluation and treatment as a specific standard of care has not been established. Surgical intervention appears to be the preferred management regardless of presentation with good outcomes. Running Title: Intracardiac Self Insertion of a Darning Needle in a Psychiatric Patient

Malignant thyroid teratoma (MTT) is a very rare thyroid malignancy. These neoplasms have been reported only in case reports and small-sized case series so far. In this study, we searched for MTTs in the Surveillance, Epidemiology, and End Result (SEER) program during 1975-2016. Subsequently, we incorporated the SEER data with published MTT cases in the literature to analyze the characteristics and prognostic factors of MTTs. Integrated data were analyzed using Chi-square or Fisher’s exact test for categorical covariates, and t-test or Mann-Whitney test for continuous variables. We included 28 studies with 36 MTT cases and found additional 8 cases from the SEER program for final analyses. Our results showed that MTT is typically seen in adult females. These neoplasms were associated with an aggressive clinical course with high rates of extrathyroidal extension (80%) and nodal involvement (62%). During follow-up, the development of recurrence and metastases were common (42% and 46%, respectively), and one-third of patients died at the last follow-up. Large tumor size (p = 0.022) and the presence of metastases during follow-up (p = 0.008) were associated with a higher mortality rate. In conclusion, our study demonstrated the characteristic features of MTT patients and outlined some parameters associated with a negative outcome which could help clinicians better predict the clinical course of these neoplasms.

Abdominal Arteries

Segmental arterial mediolysis (SAM) is a non-inflammatory, non-atherosclerotic vasculopathy mostly involving the abdominal arteries. SAM was recently recognized as a more prevalent aetiology of abdominal pain than initially thought by healthcare providers. It is still a commonly missed diagnosis in patients with recurrent emergency room (ER) visits for abdominal pain. Most published case reports in the past have highlighted catastrophic sequelae such as intra-abdominal haemorrhage requiring surgical intervention. We report a case of SAM where the diagnosis was initially missed. After diagnosis, conservative medical management was offered which led to clinical improvement.

Both malaria and leishmania  are most widespread protozoon parasitic diseases, certainly in tropical countries of the world. Malaria leishmania coinfection is common in leishmaniasis endemic areas which is mostly endemic to malaria too. Researchers notice that in cases of malaria leishmania coinfection , leishmania species find the some extent the outcome of malaria infection , but also behavior of malaria parasite species play a significant role to figure the consequences of it. While L. donovani protect from severe malaria complications by suppression of major histocompatibility class Ⅱ , so it diminish the clinical severity of malaria but not malaria parasite density due to dysfunction of major histocompatibility class I, which controlled by suppressed one, In another side L. mexicana tends to sequester in macrophages and lead to severe clinical outcomes when it coexisted with malaria parasite at same host. Experimental studies required to know more information about coinfection of different malaria and leishmania species to establish clinical research. Leishmania infection excluded when studies aim to assess the immune response to only malaria parasite, experimental studies required involving different species of malaria and leishmania.
