Abstract:

“Occult,” a 1902 international encyclopedia of religion tells us, is derived “from Latin occultus—Hidden,” and is applied to the assumption that insight into and control over nature is to be obtained by mysterious or magical procedures and by long apprenticeship in secret lore. The physical science of the middle ages, alchemy and astrology, and in modern times spiritualism, theosophy, and palmistry contain various factors of occult lore. Such doctrines, known as occultism, fall outside the realm of modern science. See MAGIC.

Abstract:

Occult primary tumors, or cancers of unknown primary, account for 5% to 10% of all diagnosed cancers, and are manifested by a wide variety of clinical presentations, while conferring a poor prognosis for most patients. Even after postmortem examination, the primary tumor is not identified in 20% to 50% of patients. Multiple sites of involvement are observed in more than 50% of patients. Although certain patterns of metastases suggest possible primaries, occult primaries can metastasize to any site. In most patients, occult primary tumors are refractory to systemic treatments, and chemotherapy is only palliative and does not significantly improve long-term survival. However, special pathologic studies can identify subsets of patients with tumor types that are more responsive. Treatment options should be individualized for this selected group to achieve improved response and survival rates. Important updates for the NCCN guidelines include the additions of tables on tumor-specific markers and their staining pattern as well as analysis of undifferentiated carcinoma.

Abstract:

Abstract In the 1903 text Madar al-Zar (The Damages of Zar), Egyptian writer Muhammad Hilmi Zayn al-Din decried the growing popularity of zar rituals and the superstitious women who participated in them as an epidemic ravaging his country. This article employs Anjuli Fatima Raza Kolb’s method of “epidemiological reading” to reveal and analyze the racial and imperial anxieties that underlie this understudied text. The article begins with a summary of Madar al-Zar and an account of the sociopolitical context in which it was published. It then pulls back the surface layers of the text to reveal that the “disease” running rampant in early twentieth-century Egypt was not zar, but the scourge of African enslavement and the ever-looming specter of Egypt’s imperial desires in Sudan. The article concludes with a meditation on zar as an archive of African dispossession, displacement, and resilience.

Abstract:

Background: Occult fractures may cause multiple morbidities. If occult fractures were detected earlier, complications may be preventable. This umbrella review and updated meta-analysis will aim to evaluate the use of imaging modalities in detecting occult scaphoid and hip fractures. Methods: The protocol for this study is available in the International Prospective Register of Systematic Reviews (PROSPERO) database (CRD42024525388). The literature search started and ended on 17 March 2024. We searched seven academic databases: MEDLINE, Cochrane Library, Pubmed, Science Direct, Google Scholar, WHO International Clinical Trials Registry Platform, and The Joanna Briggs Institute (JBI) database. The meta-analysis was conducted with the STATA program using the “midas” command. Results: There are four systematic reviews evaluating occult hip and femoral fractures with 6174 patients and two reviews evaluating occult scaphoid fractures with 1355 patients. The prevalence of occult scaphoid fracture and occult hip and femoral fractures is 23.87% (95% CI 18.25–29.49) and 44.8% (95% CI 39.38–51.4), respectively. Magnetic resonance imaging (MRI) had the best posterior probability of positive likelihood ratio (LR+) with 95% and 96% and negative likelihood ratio (LR-) with 0.15% and 1% for both occult scaphoid and hip fractures, respectively, assuming a 25% baseline. MRI could both confirm and exclude occult hip fractures while it can only confirm occult scaphoid fractures. Bone scans are inappropriate for either type of occult fractures The level of evidence for occult scaphoid fracture is weak while it is suggestive for occult hip fractures. Conclusion: The findings strengthen the use of MRI after an initially negative radiograph fracture for occult hip and femoral fractures, with a CT scan as a viable second option.

Abstract:

The article aims to examine V.I. Kryzhanovskaya’s literary work as a means by which representatives of the occult environment introduced the general public to the diversity of occult doctrines. Based on archival and published sources, the article delineates the occult preferences of V.I. Kryzhanovskaya, describes the phenomenon of popular occultism in the context of the occult market in Russia in the late 19th – early 20th century, offers a definition of “occult novel” and reveals its understanding by occultists as a means of spreading occult views. The artistic space of fantastic literature is defined as a space alternative to the spaces of both reality and fantasy, and claiming to perform a mediating function between subjective and objective experience. The author suggests that fiction for the occult served not only as an artistic means of transmitting views, but also as an ideal artistic medium, allowing the question of the reality of occult phenomena to remain open, leaving the final decision to the reader

Abstract:

Increased use of thoracic CT (TCT) in diagnosis of blunt traumatic injury has identified many injuries previously undetected on screening chest x-ray (CXR), termed “occult injury.” The optimal management of occult rib fractures, pneumothoraces (PTX), hemothoraces (HTX), and pulmonary contusions is uncertain. Our objective was to determine the current management and clinical outcome of these occult blunt thoracic injuries. A retrospective review identified patients with blunt thoracic trauma who underwent both CXR and TCT over a 2-year period at a Level I urban trauma center. Patients with acute rib fractures, PTX, HTX, or pulmonary contusion on TCT were included. Patient groups analyzed included: 1) no injury (normal CXR, normal TCT, n = 1337); 2) occult injury (normal CXR, abnormal TCT, n = 205); and 3) overt injury (abnormal CXR, abnormal TCT, n = 227). Patients with overt injury required significantly more mechanical ventilation and had greater mortality than either occult or no injury patients. Occult and no injury patients had similar ventilator needs and mortality, but occult injury patients remained hospitalized longer. No patient with isolated occult thoracic injury required intubation or tube thoracostomy. Occult injuries, diagnosed by TCT only, have minimal clinical consequences but attract increased hospital resources.

Abstract:

ABSTRACT Occult (in English, occult) means things that involve actions (roles) or supernatural influences (supernatural) or that involve powers that are beyond human power or hidden knowledge (Webster, 1993). According to Baldwin, the meaning of "hidden" Occultism is not limited to things that are not seen or detected, but the substance has the purpose of manipulating or influencing other people (Elwell, 1984). God's Word says people rely on and hope in God patiently blessed (Jer. 17:5-7). If we read in Deuteronomy 18:9-13, God's Word forbids us to follow the occult. Occult issues need serious attention. Overcoming the use of the occult is a must as well as an obligation for believers to overcome it. By using qualitative methods t writer tries to explain the important role of God's Word in overcoming the dangers of using the occult. With this method, the writer tries to have a frame of mind about what is discussed in response to the dangers of using the occult, the composition of journals in research. The basic truth of God's Word, the writer has the belief that truth is very much needed in the face of the dangers of the occult. Keywords: Occult, Word and overcome.

Abstract:

Abstract This article revisits Terence Ranger’s call for scholars of the occult in Africa to better historicize, contextualize, and disaggregate the subject. I argue that Ranger’s imperative fails to define what type of object of study the occult is and take seriously the ‘aggregation’ of the occult as an empirical ethnographic fact. I suggest that ‘the occult’ is often experienced as both a proliferating series of oracular institutions for contending with feelings of affliction, and as invisible forces whose origin and nature are compound. I turn to James Siegel’s work on witchcraft to bring attention to the experiential dimension of the occult, and provide an extended ethnographic account of a moment in which the source, nature, and means of redress of an individual’s occult affliction cannot be determined. I argue, in line with Siegel, that historicization and contextualization, while important, risk denaturing the occult and impairing our understanding of its persistence.

Abstract:

Background/Aim. Usefulness of capsule endoscopy (CE) for diagnosing small-bowel lesions in patients with obscure gastrointestinal bleeding (OGIB) has been reported. Most reports have addressed the clinical features of overt OGIB, with few addressing occult OGIB. We aimed to clarify whether occult OGIB is a definite indication for CE.Methods. We retrospectively compared the cases of 102 patients with occult OGIB and 325 patients with overt OGIB, all having undergone CE. The diagnostic yield of CE and identification of various lesion types were determined in cases of occult OGIB versus overt OGIB.Results. There was no significant difference in diagnostic yield between occult and overt OGIB. The small-bowel lesions in cases of occult OGIB were diagnosed as ulcer/erosive lesions (n=18, 18%), vascular lesions (n=11, 11%), and tumors (n=4, 3%), and those in cases of overt OGIB were diagnosed as ulcer/erosive lesions (n=51, 16%), vascular lesions (n=31, 10%), and tumors (n=20, 6%).Conclusion. CE detection rates and CE identification of various small-bowel diseases do not differ between patients with occult versus overt OGIB. CE should be actively performed for patients with either occult or overt OGIB.

Abstract:

Background: The number of researches on occult non-small cell lung cancer (NSCLC) is modest. Herein, we defined the clinicopathological features, prognosis and survival outcome of this underappreciated tumor, with purpose of obtaining a clearer picture on this disease. Methods: The entire cohort was categorized into two groups (occult NSCLC and other NSCLC) and further into five groups (occult, T1, T2, T3 and T4). A least absolute shrinkage and selection operator (LASSO) penalized Cox regression model was performed to identify the prognostic indicators. A nomogram and a risk-classifying system were formulated. Kaplan–Meier with Log-rank method was carried out to compare overall survival (OS) and cancer specific survival (CSS) differences between groups. Results: 59,046 eligible NSCLC cases (occult NSCLC: 1158 cases; other NSCLC: 57,888 cases) were included. Occult NSCLC accounted for 2.0% of the included cases. Multivariate analysis revealed that age, sex, tumor location, histology, grade and surgery were prognostic factors for OS. The corresponding prognostic nomogram classified occult NSCLC patients into low-risk and high-risk group, and its performance was acceptable. Survival curves demonstrated that occult NSCLC patients exhibited worse survivals than other NSCLC. In further analyses, the survival of low-risk occult NSCLC and stage T3 NSCLC were comparable, and the high-risk occult NSCLC patients still owned the worst survival rate. Conclusions: Occult NSCLC was an aggressive tumor with poor prognosis, and surgery was the preferred treatment. More attention should be paid to this overlooked disease due to no evidence of tumor imaging.

Abstract:

Background: In Burkina Faso, the polymerase chain reaction (PCR) assay is not routinely used in the biological qualification of blood donations and this constitutes a risk factor for the transmission of occult hepatitis B virus (HBV) infection during blood transfusion. The objective of this study is to determine the prevalence of occult B infection (OBI) among blood donors for the purposes of improved blood safety in Burkina Faso. Methodology: A descriptive cross-sectional study of 300 HBsAg negative blood donors was conducted in the city of Ouagadougou, Burkina Faso from April to October 2020. Anti-HBc antibody was determined using the BOSON® brand rapid tests. HBV DNA was detected in 75 selected donors by real-time PCR (rt PCR) using the 7500 Fast Real Time PCR assay technique. Results: Of the 300 HBsAg negative donors, 208 (69.3%) were males while 92 (30.7%) were females, with average age of 30.18 years. Anti-HBc antibody was detected in 39 cases (13%). Of the 75 donor samples tested by rt PCR, 3 (4%) were positive for HBV DNA (occult B infection); 2 of which were anti-HBc antibody positive (seropositive OBI) while 1 was anti-HBc antibody negative (seronegative OBI). Conclusion: Given the prevalence of OBI of 4% in this study and its consequences in blood recipients, it appears necessary that in addition to the classic serological markers of hepatitis B, to test for the presence of HBV DNA among blood donors in order to improve transfusion safety. Keywords: Prevalence, Occult B infection; Blood donors, Ouagadougou. French title: Prévalence de l'infection occulte par le virus de l'hépatite B chez les donneurs de sang à Ouagadougou, Burkina Faso Contexte: Au Burkina Faso, la polymérase chain réaction (PCR) n’est pas utilisée lors de la qualification biologique des dons et cela constitue un facteur de risque de transmission de l’Infection Occulte du virus B (VHB) lors des transfusions sanguines. L’objectif de cette étude était de déterminer la prévalence de l’infection occulte B chez les donneurs de sang en vue d’une meilleure sécurité transfusionnelle. Méthodologie: Une étude transversale prospective, réalisée d’avril à octobre 2020 dans la ville de Ouagadougou incluant 300 donneurs de sang AgHBs négatif. L’anticorps anti HBc a été déterminé par les tests rapides de marque BOSON®. L’ADN du VHB a été recherché chez 75 donneurs par PCR en temps réel (rt PCR) avec le 7500 Fast Real Time PCR. Résultats: Parmi les 300 donneurs AgHBs négatifs, 208 (69,3%) étaient des hommes et 92 (30,7%) des femmes. L’âge moyen était de 30,18 ans. La recherche de l’Ac anti-HBc était positive dans 39 cas (13 %). Parmi les 75 échantillons passés à la rt PCR, 3 (4%) étaient positifs pour l’ADN du VHB. Sur les 3 cas d’ADN VHB positifs, 2 (66,67%) étaient positifs Ac anti HBc et 1 (33,33%) Ac anti HBc négatif. Conclusion: Compte tenu de la prévalence de l’infection occulte B et ses conséquences chez les donneurs de sang et chez les receveurs, il devient nécessaire de rechercher, en plus des marqueurs sérologiques classiques de l’hépatite B, l’ADN VHB pour une meilleure sécurité transfusionnelle. Mots clés: Prévalence, Infection occulte de l’HBV, Donneurs de sang, Ouagadougou

Abstract:

Introduction Symptoms of occult brain cancer may mimic stroke. Misdiagnosis may lead to improper treatment and delayed diagnosis. We characterised strokes associated with occult primary brain cancer and determined risk that ischaemic and haemorrhagic strokes are associated with occult primary brain cancer. Patients and methods All patients with incident stroke in Denmark 2003–2015 were identified through the Danish Stroke Registry (n = 85,893) and matched 1:10 on age and sex to the Danish background population without a stroke history (n = 858,740). This cohort was linked to the Danish Cancer Registry and prevalence of occult primary brain cancer defined as the event of previously unknown primary brain cancer during a one-year follow-up was estimated. We used Cox regression models to study risk of occult primary brain cancer in comparison to the background population. Results Of 77,484 patients with ischaemic strokes, 39 (1 in 2000) were associated with primary brain cancer; of 8409 with haemorrhagic strokes, it was 126 (1 in 66). In the background cohort, 205 (1 in 4000) had occult primary brain cancer. The multivariate stroke risk factor analysis showed that patients with occult primary brain cancer differed significantly from those without occult primary brain cancer indicating they might have stroke mimics rather than true strokes. Discussion and conclusions: Strokes associated with occult primary brain cancer tend to be stroke mimics rather than true strokes. Primary brain cancer is rare in patients with ischaemic stroke (1 in 2000); risk that misdiagnosis results in maltreatment is, therefore, very low. Occult primary brain cancers are mainly found among patients with haemorrhagic stroke; they are not uncommon (1 in 66) and should always be kept in mind.

Abstract:

Objective To assess the risk factors, adverse obstetrical outcomes, and recurrence risk associated with pathologically diagnosed occult placenta accreta. Study Design This was a retrospective observational study of clinically adherent placentas requiring manual extraction that underwent pathological examination. Cases were defined as those with histological evidence of placenta accreta, and controls were defined as those without accreta. All subsequent pregnancies were evaluated to determine the recurrence risk of occult accreta in future pregnancies. Results Of 491 women with clinically adherent placentas, 100 (20.1%) with a pathological diagnosis of occult accreta were compared with 391 (79.9%) without occult accreta. In bivariable analysis, risk factors associated with occult accreta included a history of previous cesarean (19 vs. 10.7%; p = 0.03) and prior uterine surgery (35 vs. 19.7%; p = 0.001). Adverse obstetrical outcomes were more common in women with occult accreta including postpartum hemorrhage (59 vs. 31.7%; p < 0.001) and peripartum hysterectomy (21 vs. 0.3%; p < 0.001). In 130 subsequent pregnancies, there was an increased risk of retained placenta (42.9 vs. 19%; p = 0.04) and recurrence of occult accreta (29.6 vs. 6.8%; p = 0.05). Conclusion Occult accreta is associated with an increased risk of hemorrhagic morbidity and recurrence of morbidly adherent placenta in subsequent pregnancies.

Abstract:

Abstract Bilateral testicular biopsies were performed on 708 males with acute lymphoblastic leukemia completing 24 to 30 months of maintenance chemotherapy in continuous remission. The 73 patients (10.3%) with occult testicular leukemia (TL) had a significantly increased risk of subsequent relapse (P = .0001) and death (P less than .0001) when compared with patients with negative biopsies. Protocol-specified therapy for occult TL included reinduction therapy with concurrent bilateral testicular radiation, and 2 years of maintenance therapy. Four-year event-free survival for patients with negative biopsies was 78.2% +/- 4% versus 65% +/- 14% for patients with occult TL who received protocol-specified therapy (P = .05). This study suggests that (1) occult TL occurs in 10% of males completing 2 years of maintenance therapy; (2) occult TL significantly increases risk for subsequent relapse and death; (3) treatment results for occult TL and isolated overt off therapy TL (no previous biopsy) are similar; and (4) given current therapy, documentation of occult TL after 2 years of therapy does not improve disease-free survival.

Abstract:

The practice of Occultism knows no place and time. Even though the world has undergone radical changes marked by advances in science and technology, there are still people who want to practice Occultism. Many of these occult practices are generally inherited from their ancestors and passed down from generation to generation until now. Many Christians carry out Occult actions for various reasons, such as fear of ancestral spirits, not being protected by them, or feeling that ancestral spirits do not bless them. Occult practices are actions that are far from Christian truth. The occult does exist on this earth. The purpose of this study is to analyze the current occult practice. The method used is qualitative research in the form of library research method. Therefore, a believer must be vigilant and on guard to avoid this occult practice.

Abstract:

Objective We estimated the frequency of occult gynecologic primary tumours (gpts) in patients with metastatic cancer from an uncertain primary and evaluated the effect on disease management and overall survival (os).Methods We used Manitoba administrative health databases to identify all patients initially diagnosed with metastatic cancer during 2002−2011. We defined patients as having an “occult” primary tumour if the primary was classified at least 6 months after the initial diagnosis. Otherwise, we considered patients to have “obvious” primaries. We then compared clinicopathologic and treatment characteristics and 2-year os for women with occult and with obvious gpts. We used Cox regression adjustment and propensity score methods to assess the effect on os of having an occult gpt.Results Among the 5953 patients diagnosed with metastatic cancer, occult primary tumours were more common in women (n = 285 of 2552, 11.2%) than in men (n = 244 of 3401, 7.2%). In women, gpts were the most frequent occult primary tumours (n = 55 of 285, 19.3%). Compared with their counterparts having obvious gpts, women with occult gpts (n = 55) presented with similar histologic and metastatic patterns but received fewer gynecologic diagnostic examinations during diagnostic work-up. Women with occult gpts were less likely to undergo surgery, waited longer for radiotherapy, and received a lesser variety of chemotherapeutic agents. Having an occult compared with an obvious gpt was associated with decreased os (hazard ratio: 1.62; 95% confidence interval: 1.2 to 2.35). Similar results were observed in adjusted analyses.Conclusions In women with metastatic cancer from an uncertain primary, gpts constitute the largest clinical entity. Accurate diagnosis of occult gpts early in the course of metastatic cancer might lead to more effective treatment decisions and improved survival outcomes.

Abstract:

Objectives –Toinvestigate the accuracy of the immunochemical occult blood test in screening for gastric cancer and to evaluate whether or not the upper digestive tract should be examined when the occult blood test is positive but there is no abnormal sign in the colorectum. Methods –In a case-control study an occult blood test was carried out on 150 subjects with gastric cancer, ISO subjects with colorectal cancer, and on 300 healthy subjects. Data were analysed from 44 996 persons attending a population screening programme who underwent both radiological gastric cancer screening (barium meal) and colorectal cancer examination by occult blood test. Results –In the case—control study the occult blood test was positive in 27/150 (18%) subjects with gastric cancer, in 112/150 (75%) subjects with colorectal cancer, and in 24/300 (8%) healthy controls. In the population screening programme the occult blood test was positive in 4/50 (8%) persons with gastric cancer and 3232/44 950 (7%) persons without gastric cancer,- indicating no difference between them. Conclusions –These data show that the immunochemical faecal occult blood test is worthless as a screening test for gastric cancer, and that examination of the upper digestive tract is unnecessary in cases where the faecal occult blood test is positive but there is no sign of colorectal disease.

Abstract:

Today breast cancer is the most common cancer type in women, in both developed and developing countries. However, occult breast cancer is a highly rare type in all breast cancers. For the first time in history to know, Halsted defined the term “occult breast cancer” with 2 cases of his’ in the journal, Annals of Surgery. We have 2 similar cases who were 52 and 61-years-old patients and presented our clinic with left axillary swelling and pain. On physical examination and with imaging techniques there wasn’t any primary lesion found. Examination of lymph nodes’ biopsy material was compatible with breast cancer metastasis for both of the patients and they were diagnosed with occult breast cancer. They underwent a modified radical mastectomy surgery and axillary curettage. Histopathologic examination of the excised breast material revealed T1 invasive breast cancer.International Journal of Human and Health Sciences Vol. 02 No. 04 October’18. Page : 239-243
