RESUMO

We report a pleiotropic disease due to loss-of-function mutations in RHBDF2, the gene encoding iRHOM2, in two kindreds with recurrent infections in different organs. One patient had recurrent pneumonia but no colon involvement, another had recurrent infectious hemorrhagic colitis but no lung involvement and the other two experienced recurrent respiratory infections. Loss of iRHOM2, a rhomboid superfamily member that regulates the ADAM17 metalloproteinase, caused defective ADAM17-dependent cleavage and release of cytokines, including tumor-necrosis factor and amphiregulin. To understand the diverse clinical phenotypes, we challenged Rhbdf2-/- mice with Pseudomonas aeruginosa by nasal gavage and observed more severe pneumonia, whereas infection with Citrobacter rodentium caused worse inflammatory colitis than in wild-type mice. The fecal microbiota in the colitis patient had characteristic oral species that can predispose to colitis. Thus, a human immunodeficiency arising from iRHOM2 deficiency causes divergent disease phenotypes that can involve the local microbial environment.

RESUMO

BACKGROUND The nasopalatine canal (NPC), or incisive canal, is located in the midline of the palate, posterior to the maxillary central incisors. Its anatomy is important in prosthetic dentistry procedures. This study aimed to assess the anatomical morphology of the NPC according to age, sex, and dental status using cone-beam computed tomography (CBCT) in 335 patients. MATERIAL AND METHODS In this retrospective cross-sectional study, a total of 335 patients were recruited and categorized according to sex, age, and dental status. Individual CBCT images were analyzed in the sagittal, coronal, and axial planes. Also, we recorded the dimensions and morphological shape of the NPC and adjacent buccal bone plate (BBP) under standardized conditions. The associations between sex, age group, NPC shapes and types, and presence of central incisors were assessed. A significance level was set at P<0.05. RESULTS Mean labio-palatal and mediolateral measurements of the incisive foramen were 5.13±1.45 mm and 3.21±0.96 mm, whereas the mean diameter of Stenson foramen was 2.57±1.25 mm, and the total length of the NPC was 11.79±2.50 mm. Funnel, Y, and round-shaped canals were the most prevalent shapes of the NPC in sagittal, coronal, and axial planes. BBP was greater in men, with P=0.011, P=0.000, and P=0.001 at BBP1, BBP2, and BBP3, respectively. CONCLUSIONS NPC and BBP parameter values were slightly higher among male patients. NPC parameters increased with older age. The crest width of BBP decreased with older age and after missing maxillary central incisor teeth.

RESUMO

Tetrahydrothiophenocucurbit[5 and 6]uril has been synthesized from tetrathiophenoglycoluril diether, providing thioether functionality at the exterior equatorial position of the cucurbituril cage. This functionality has been investigated for chemical modification through sulfoxide formation and subsequent Pummerer rearrangement to the acetoxy derivative of the tetrahydrothiophenocucurbit[5]uril. Nanoparticles of Au and Ag were prepared in the presence of tetrahydrothiophenocucurbit[6]uril, which curiously led to the formation of nanoparticle chains, growing in length over days to weeks.

RESUMO

BACKGROUND: Depression is the most common psychiatric disorder in HIV/AIDs patients, and its prevalence is three times higher in HIV/AIDs patients. Globally, over 35 million people were living with HIV/AIDs, 24.7 million were in Sub-Saharan Africa. The study aims to estimate the prevalence and determine factors associated with depression among HIV/AIDs adult patients in the ART unit at Banadir Hospital Mogadishu, Somalia. METHOD: A hospital-based cross-sectional study was conducted between 1 May and 1 July 2022. Samples were recruited from the HIV/AIDs adult patients attending in ART unit at Banadir Hospital, Mogadishu, Somalia. A validated research tool, including sociodemographic, behavioral, clinical, and psycho-social characteristics, three items social support scale, an 11-item HIV stigma scale, and patient health questions-9 (PHQ-9) were used. The interview was conducted privet room in the ART unit. Logistic regression was used to determine factors associated with depression at the significance level a = 0.050. RESULT: The overall prevalence of depression among HIV/AIDs patients was 33.5% (95%CI = 28.1-39.0). In the multivariable logistic regression, three factors were associated with depression; the odds of depression were 3.415 times (95%CI=1.465-7.960) greater for those with poor social support than those with moderate-strong social support. Those with moderate and poor treatment adherence had 14.307 times (95%CI=5.361-38.182) greater odds of depression than those with good treatment adherence. Those who use substances had 3.422 times (95%CI=1.727-6.781) greater odds of having depression than those who did not. CONCLUSION: People living with HIV in Mogadishu, Somalia, suffer from depression. The implementation to reduce depression should be focused on empowering social support, developing an appropriate approach to increase treatment adherence, and reducing or eliminating substance use.

RESUMO

BACKGROUND: In September 2022, a new Ebola outbreak was reported in Uganda, East Africa, and 142 confirmed cases, including 19 Healthcare workers (HCWs) reported. Ebola is not endemic in Somalia, but the country is at a reasonable risk of the virus being introduced due to the direct connection with daily flights from Uganda without border health control and prevention activities. Therefore, evaluating HCWs' Knowledge and attitude is crucial since this is the first time being evaluated in Somalia. The study's objective is to evaluate the HCWs' Knowledge and attitude toward the Ebola virus disease in Somalia. METHOD: An online self-administrated cross-sectional survey was conducted among HCWs (n = 1103) in all six federal member states of Somalia using a validated, reliable, well-structured questionnaire. Data we analyzed using descriptive statistics and Logistic regression were used to determine sociodemographic characteristics associated with poor Knowledge and negative attitude. RESULT: Over one-third (37.3%) of HCWs had poor Knowledge; the mean knowledge score was 7.97 SD ± 2.15. Almost 40.1% of the HCWs had a negative attitude; the mean attitude was 27.81 SD ± 8.06. Low-income HCWs (AOR = 2.06, 95%CI:1.01-4.19), Married HCWs (AOR = 1.39, 95%CI: 1.110-1.963), Midwives (AOR = 2.76, 95%CI: 1.74-4.39), Lab technicians (AOR = 2.43, 95%CI: 1.43-4.14), HCWs work in Jubaland state of Somalia (AOR = 3.69, 95%CI: 2.39-5.70), Galmudug state (AOR = 8.50, 95%CI: 4.59-15.77), Hirshabelle state (AOR = 3.18, 95%CI: 2.15-4.71) were more likely to have poor Knowledge compared to their counterparts. HCWs who work in Hirshabelle state (AOR = 5.44,95%CI: 3.58-8.27), Jubaland state (AOR = 8.47, 95%CI: 4.69-15.29), and Galmudug state (AOR = 4.43, 95%CI: 3.03-6.48) was more likely to have a negative attitude than those working in the Banadir region administration. CONCLUSION: Most Somali healthcare workers showed good Knowledge and a positive attitude toward the Ebola virus. The implementation to enhance Knowledge and attitude must specifically focus on low-income HCWs, Midwives, Lab technicalities, and those who work in Hirshabelle, Jubaland, and Galmudug states of Somalia.

RESUMO

The preparation of gold nanoparticles (AuNPs) from tetrachloroauric acid in the presence of tetrahydrothiophenocucurbit[n]uril (THTmQ[n]) has been effectively achieved in a microwave reactor. The reaction was performed in the presence of an excess of the tetrahydrothiopheno function in a partial reductant role, while the remainder formed AuNP-THTmQ[n] conjugates after the reduction was completed with formic acid. An affinity for the AuNPs by the THTmQ[n] was observed in the purification of the NPs via centrifugation, removal of the supernatant and resuspension of the conjugate.

RESUMO

The increasing availability of next-generation sequencing for clinical research dramatically improved our understanding of breast cancer genetics and resulted in detection of new mutation variants. Cancer risk data relating to some of these variants are insufficient, prompting the designation of variants of uncertain significance (VUS). The histopathologic characteristics of these variants have not been previously described. We propose to depict these characteristics and determine if invasive carcinomas with similar VUS genes share similar histomorphologic features. In total, 28 invasive breast cancers with VUS were retrospectively identified. Tumor sections were reviewed and a predefined set of histopathologic characteristics were documented and compared. Nine of the 28 cases were variants in the ATM gene and were found to share similar histologic characteristics; all had tumor cells with low nuclear grade, absent tumor infiltrating lymphocytes, as well as a marked desmoplastic response. A subset of the above findings were identified in variants of other genes but none had all findings collectively. Furthermore, variants of ATM gene had smaller tumor size, lower pathologic T stage at presentation, and more favorable surrogate molecular subtype compared to variants of other genes. These findings could potentially be used to reclassify VUS and predict which patients may harbor ATM mutations, and hence could have implications in triaging toward ATM variant identification for potential future targeted therapy.

RESUMO

Extrapulmonary small cell carcinoma (EPSCC) refers to small cell carcinoma arising outside of the lungs. EPSCC extrapulmonary small cell carcinoma is a rare aggressive neoplasm, representing a minority of all small cell carcinomas. Despite its uncommon occurrence, EPSCC extrapulmonary small cell carcinoma has been described in nearly every organ, most commonly in the gastrointestinal and genitourinary systems. As such, it is important for radiologists to be aware of the entity. Although imaging is neither sensitive nor specific for EPSCC extrapulmonary small cell carcinoma , it plays an important role by helping exclude metastases from a primary pulmonary tumor, establish tumor staging, and assess response to therapy. EPSCC extrapulmonary small cell carcinoma is diagnosed by demonstrating pathologic features of small cell carcinoma in an extrapulmonary site. There are two ways to stage EPSCC extrapulmonary small cell carcinoma . One method uses the Veterans Administration Lung Study Group system developed for small cell lung cancer that allocates patients into limited or extensive disease categories. The second approach is the American Joint Committee on Cancer tumor-node-metastasis system applied to other tumor subtypes arising from the same organ. Because of its rare and varied manifestations, the most effective treatment for EPSCC extrapulmonary small cell carcinoma has not been established. Current management recommendations are derived from retrospective studies and single-institution experiences or are extrapolated from small cell lung cancer data. Regardless of therapy, overall survival rates are poor, with 5-year survival rates around 13%. To help radiologists increase their familiarity with EPSCC extrapulmonary small cell carcinoma , this article provides (a) a background for EPSCC extrapulmonary small cell carcinoma based on the literature and (b) a pictorial review of EPSCC extrapulmonary small cell carcinoma in multiple organs, with radiologic-pathologic correlation.

RESUMO

AIM: The aim of this study was to determine the mode of delivery and birthweight among teenagers in comparison to adult pregnant Saudi women. MATERIAL AND METHODS: This was a retrospective comparative study. We included all primigravid teenage girls aged 19 years or younger and adult women aged 20-29 years with singleton term normal pregnancies who delivered at Hail Maternity Hospital during 1 January-31 December 2013. RESULTS: Incidence of vaginal delivery among teenagers was higher than that in adults, at 105 (80.2%) and 588 (70.5%), respectively. There was a lower incidence of vacuum extraction and cesarean section among the teenage group compared to the adult group (1 [0.8%] vs 25 [3.0%], and 25 [19.1%] vs 221 [26.5%], respectively [P > 0.05]). Incidence of low birthweight among the teenage group was higher than that in adults (28 [21.4%] and 84 [10.1%], respectively [P < 0.05]). CONCLUSION: Our study concluded that teenage pregnancy is associated with a high risk of low birthweight (P < 0.05). Adult mothers experienced more cesarean section and vacuum extraction deliveries (P > 0.05). Adequate antenatal care, community education and raising awareness might decrease the number of teenage pregnancies, which was 13.6% in our study.

RESUMO

Cardiac failure is a clinical syndrome that may develop in children owing to cardiac dysfunction or underlying structural heart diseases. Considering the differences in diagnostic and therapeutic approaches for pediatric heart failure (PHF) and adult heart failure, we have reviewed the current literature on PHF. Relevant studies were extracted from MEDLINE/PubMed, Google Scholar, and Clinical Trial Registries using the terms "pediatric heart failure" or "heart failure in children" and "management" or "decongestive therapy." Recent advances in diagnostic approaches, such as cardiac magnetic resonance, speckle-tracking echocardiography, tissue Doppler imaging, and molecular diagnostic techniques, have increased our under -standing of PHF. It is imperative that clinicians evaluate the interrelated factors responsible for the develop ment of PHF, including myocardial function, pulmonary and systemic blood flow, heart rhythm, valve function, and nutritional status. Although recent advances have demon strated the efficacy of many new drugs in adult heart failure trials, it cannot be concluded that these drugs will show similar efficacy in children, considering the heterogeneous nature of the underlying mechanisms and variable pharmacody-namics and pharmacokinetics. Therefore, the underlying pathophysiology of PHF and the mechanisms of action of different drugs should be considered when selecting appropriate therapies. Further trials are needed to establi sh the efficacy and safety of these drugs, and a combined mul-ti disciplinary strategy will help enhance PHF outcomes.

RESUMO

Background: In Saudi Arabia, a traditional therapy for a folk labeled problem known as "Autheem - " is often offered to infants. The procedure involves manipulating an infant's soft palate to alleviate pain associated with infant colic and poor feeding. However, concerns remain about this procedure's impact on infant health and its potential to transmit infections. This study focused on perceptions that Saudi mothers hold about Autheem therapy. Methods: A descriptive, cross-sectional, community-based study was conducted via an online platform to reach Saudi mothers in the Riyadh region of Saudi Arabia. Results: Five hundred and thirty-six Saudi mothers participated; half were older than 30 years of age. Despite a high rate of college degree attainment, the majority of mothers relied on their elders as a source of information (88.4%). Autheem was viewed to be a stand-alone disease by 86.5% of respondents; 71.4% believed it could not be treated with modern medicine. Most infants were under six months of age when they received Autheem therapy (72%). Roughly 13% of mothers found that their infant had a fever after the therapy; we found an association between Autheem therapy and viral illnesses. About 13% of mothers altered their child's vaccination schedule after Autheem therapy. Conclusion: Older mothers have more positive attitudes towards and stronger beliefs in Autheem therapy than younger mothers. The therapy's strong association with viral illnesses and its negative impact on vaccination schedules are major public health concerns.

RESUMO

PURPOSE: The objective was to evaluate the periodontal clinicoradiographic status and whole salivary prostaglandin E2 (PgE2) levels among users of water pipe and cigarettes. MATERIALS AND METHODS: Demographic data, duration of smoking (pack years), and familial history of smoking were recorded using a questionnaire. Participants were allocated into three groups based on their smoking status: group 1: self-reported cigarette smokers (CS); group 2: self-reported water-pipe-users; and group 3: non-smokers. The assessment included measurements of full-mouth plaque and gingival indices (PI and GI), as well as probing depth (PD), clinical attachment loss (CAL), and marginal bone loss (MBL). Unstimulated whole saliva samples were collected and PgE2 levels were measured. Group comparisons were done and p<0.05 was considered statistically significant. RESULTS: Thirty-three, 34 and 33 individuals were included in groups 1, 2 and 3, respectively. Full mouth PI (p<0.05), GI (p<0.05), PD (p<0.05) and mesial (p<0.05) and distal (p<0.05) MBL were statistically significantly higher among patients in groups 1 and 2 than group 3. The scores of CAL in groups 1 and 2 were 3.45 ± 0.97 and 3.62 ± 1.2 mm, respectively. None of the individuals in the control group displayed CAL. PgE2 levels were statistically significantly higher among patients in groups 1 (231.5 ± 66.3 pg/ml) (p<0.05) and 2 (231.5 ± 66.3 pg/ml) (p<0.05) compared with group 3 (76.6 ± 10.6 pg/ml). In groups 1 and 2, a statistically significant relationship was observed between pack-years, the duration of water-pipe smoking, and the levels of PgE2 and PD. CONCLUSION: There is no difference in periodontal clinicoradiographic status and whole salivary PgE2 levels between CS and waterpipe-users; however, these parameters are worse in CS and water-pipe users than in non-smokers.

RESUMO

Objectives: The emergence of resistance to antiretroviral therapy (ART) has an impact on the cost of HIV care. This study aimed to estimate the direct and indirect costs associated with the first episode of drug resistance in individuals with HIV receiving first-line ART. Methods: We developed a cost calculator to estimate the cost of drug resistance over a period of 12 months in the Kingdom of Saudi Arabia. The model inputs (estimated using expert opinion and publicly available sources) included costs associated with testing for resistance, adverse events of a new regimen, and indirect costs. Results: The direct and indirect medical expenses for the year resistance developed were 6980 Saudi Arabian riyal (SAR) and SAR 2862, respectively. The addition of the cost of new ARTs would increase the total annual costs (between SAR 5174 and SAR 34,265 per patient). One-way sensitivity analysis also reported significant impact of initial and switching therapies used after resistance develops on the total costs of resistance per year. Conclusions: There is a significant cost burden associated with drug resistance, which emphasizes the need to select an appropriate initial ART regimen that has a strong genetic barrier and conduct pre-treatment resistance tests (if possible).

RESUMO

Background: Alloimmunisation remains a major consequence of blood transfusion among sickle cell disease (SCD) and thalassemia patients due to the exposure to non-self-red blood cell (RBC) antigen. The complication is associated with transfusion reactions and delayed transfusion procedure because of the difficulty of finding compatible blood. This study aims to determine the prevalence of alloimmunisation to RBC and alloantibody specificities among SCD and thalassemia patients in, an endemic area of SCD and thalassemia, Jazan province of Saudi Arabia, from three major hospitals. Methods: This is a retrospective, multicenter cross-sectional study conducted on 1027 patients with SCD and thalassemia, which received Rh/K matched transfusions in 2019 in the three centers. Demographic data and medical records of participants from three transfusion institutions were collected and analysed. Results: A total of 1027 were enrolled in the cohort; 906 (88.2%) and 121 (11.8%) patients with SCD and thalassemia, respectively. There were 483 (47%) males and 544 (53%) females with median age of 15 (range 1-48). Among the studied population, 78 were alloimmunised with an overall alloimmunisation rate of 7.6%. These patients developed a total of 108 alloantibodies, and anti-E was the most detected antibody (25.9%) followed by anti-K (24.1%). Conclusion: The overall rate of alloimmunisation to RBC antigen among the studied population in Jazan was low compared to other areas in the country. Most alloantibodies detected were against E and K antigens. The knowledge of most encountered alloantibodies in our population will aid in selecting the most appropriate antigen-negative red cells. Further research, however, is needed to explore factors associated with residual risk of alloimmunisation in these patients.

RESUMO

BACKGROUND: The aim was to assess the peri-implant clinicoradiographic status and prostaglandin E2 (PGE2) levels in peri-implant sulcular fluid (PISF) samples collected from individuals with cement-retained and crew-retained implants. METHODS: In this observational study, participants with cement-retained and screw-retained implants were enrolled. A questionnaire was utilized to gather demographic information and assess the educational background of the participants. Peri-implant modified plaque and bleeding indices, probing depth, and crestal bone loss were measured. Subsequently, PISF samples were collected, and corresponding volumes were recorded. Commercial kits employing enzyme-linked immunosorbent assay were employed to quantify PGE2 levels. The sample size was determined, and group comparisons were conducted using the Student t test and the Mann-Whitney U-test. Logistic regression models were constructed to evaluate the correlation between PGE2 levels and clinicoradiographic and demographics. The predefined level of significance was established at P < .05. RESULTS: Sixty-seven participants, consisting of 33 with cement-retained implants and 34 with screw-retained implants, were included in the study. The mean ages for individuals with cement and screw-retained implants were 54.2 ± 8.7 and 58.7 ± 7.4 years, respectively. The majority of participants had completed university-level education. Reportedly, 87.9% and 82.4% of individuals with cement and screw-retained implants, respectively brushed teeth twice daily. No significant differences were observed in clinicoradiographic parameters, PGE2 volume, and levels between cement-retained and screw-retained implants. There was no correlation between PGE2 levels and peri-implant clinicoradiographic parameters among individuals with either cement-retained or screw-retained implants. CONCLUSIONS: Cement-retained and screw-retained implants exhibit a consistent peri-implant clinicoradiographic status, accompanied by stable levels of PGE2 in PISF provided oral hygiene maintenance regimens are stringently followed.

RESUMO

Due to the limited hydrophobic properties of porcelain insulators, applying anti-pollution flashover coatings is crucial to enhance their functionality. This research outlines a classification system for assessing contamination levels on 22 kV porcelain insulators, both with and without coatings. It synthesizes six classification criteria derived through both numerical simulations and experimental studies to effectively gauge contamination severity. The study examined insulators treated with Room Temperature Vulcanizing (RTV) silicone under three different conditions: uncoated, partially coated, and fully coated. Additionally, the research assessed the effects of humidity on these polluted insulators to understand environmental impacts on their performance. The criteria, which are the flashover voltage (x1), fifth to third harmonics of leakage current (x2), maximum electric field (x3), total harmonic index (x4), insulation resistance (x5) and dielectric loss (x6), were proposed for evaluating the insulator's string condition. The finite element method (FEM) was used to simulate an electric field. Then, based on the proposed criteria, the performances of the Random Forest (RF), Support Vector Machine (SVM), K-Nearest Neighbor (KNN), and Multi-layer Perceptron (MLP) have been trained and compared to classify polluted insulator conditions with and without coating. The established criteria facilitate precise monitoring of the condition of high-voltage insulators, ensuring quick and effective responses that support the stability of the electrical power system.

RESUMO

BACKGROUND: This systematic review aims to synthesize existing research on parental knowledge, attitudes, and barriers to human papillomavirus (HPV) vaccination in the Gulf Cooperation Council (GCC) countries. METHODS: Following PRISMA guidelines, this systematic review analyzed parental knowledge, attitudes, and barriers to HPV vaccination in 6 GCC countries. A comprehensive search across multiple electronic databases (Embase, Cumulative Index of Nursing and Allied Health Literature, Scopus, Ovid MEDLINE, Web of Science, and PubMed) was conducted, focusing on studies published between January 2010 and December 2023. Inclusion criteria targeted studies in English or Arabic involving parents in GCC countries, excluding non-research publications and those not using survey techniques. RESULTS: The review included 7 studies from Saudi Arabia, the United Arab Emirates, and Qatar. No study was found in Oman, Bahrain, and Kuwait. The findings highlighted low knowledge and awareness of HPV and the vaccine, with significant variation across studies. According to our review findings, the level of awareness in the 7 studies was found to be low to high. These studies collectively illustrate a range of awareness levels, from as low as 11% awareness of the HPV-cervical cancer link to as high as 68% general awareness of HPV. Attitudes towards vaccination were poor in Saudi Arabia but more positive in the United Arab Emirates and Qatar. Major barriers included safety concerns, lack of information, and cultural beliefs. CONCLUSION: Despite moderate awareness in some GCC countries, substantial knowledge gaps and vaccine hesitancy persist. Targeted educational campaigns, effective communication strategies, and involvement of community leaders are essential to improve HPV vaccination uptake.

RESUMO

The Médecins Sans Frontières Tertiary Orthopaedic Care center in Mosul, Iraq, provides reconstructive surgery, microbiological analysis, integrated infection prevention and control, and antibiotic stewardship services. Between May 2018 and February 2020, we recorded soft tissue and/or bone infections caused by gram-negative extensively drug-resistant (XDR) bacteria in 4.9% (13/266) of the admitted patients. The XDR bacteria identified among 12 patients in this case series were extended-spectrum ß-lactamase-producing Klebsiella pneumoniae (n = 5, 41.7%) with intermediate sensitivity or resistance to imipenem and/or meropenem, Acinetobacter spp (n = 3, 25.0%; 2 Acinetobacter baumannii strains) resistant to imipenem and/or meropenem, Pseudomonas aeruginosa (n = 2, 16.7%) resistant to imipenem and meropenem, and extended-spectrum ß-lactamase-producing Proteus mirabilis (n = 2, 16.7%) resistant to meropenem. Most XDR isolates were sensitive only to colistin or polymyxin B, neither of which is available in Iraq. Therefore, the only treatment option was multiple rounds of surgical debridement and wound care. The infection was deemed cured before discharge in 7 patients (58.3%). Meanwhile, 4 patients (33.3%) were discharged with unhealed wounds, and outpatient follow-up was planned. One patient died in the intensive care unit of a referral hospital after developing septicemia postsurgery. XDR bacteria pose substantial health risks in Iraq. Thus, improving antimicrobial stewardship and accessibility to essential antibiotics is critical to address this issue.

RESUMO

Granulomatous mastitis (GM) is a rare benign breast disease that affects women of childbearing age, usually within five years of pregnancy. The hallmark diagnostic feature of GM is the presence of lobular granulomatous inflammation. The occurrence of this clinicopathological entity is usually idiopathic. Nevertheless, GM has often been associated with systemic inflammatory conditions of either infectious (such as tuberculosis) or autoimmune etiology (particularly sarcoidosis, vasculitis, and less likely systemic lupus erythematosus [SLE]). In this report, the authors described an unusual case of GM that was associated with features of SLE in a young female patient who presented with a painful breast lump. Histopathological examination of the lump's biopsy showed GM. Further laboratory workup revealed evidence of some immunological criteria of SLE. Steroid therapy led to the resolution of the patient's breast swelling. The breast mass remained in remission with hydroxychloroquine treatment. Only a handful of similar cases in the current literature demonstrated a plausible association between SLE and GM. Our case provides a reference to consider SLE as a possible differential diagnosis when GM is encountered in young-aged female patients.

RESUMO

Percutaneous endoscopic gastrostomy (PEG) is a relatively safe procedure that represents an important supportive adjunctive component for patients with primary head and neck squamous cell carcinoma (HNSCC). The HNSCC population is considered a high-risk group for developing critical nutritional deficiency due to a multitude of factors. Nevertheless, as the use of PEG in modern practice is gaining more popularity due to various indications, unusual complications have been increasingly reported. PEG site metastasis from primary HNSCC has emerged as a rare, yet serious oncological phenomenon that warrants careful consideration. The authors report an unusual case of squamous cell carcinoma (SCC) of the hypopharynx that metastasized to the gastric body mucosa through a PEG site. The metastatic SCC presented as massive gastrointestinal bleeding, and esophagogastroscopy revealed an ulcerated mass in the gastric body masquerading as a primary gastric adenocarcinoma. Histopathology and immunohistochemistry examination confirmed metastatic SCC which concurred with the patient's primary hypopharyngeal SCC. The review of the updated literature revealed that a total of 121 cases of this rare oncological entity have been reported to date. Physicians need to be vigilant of the symptoms of PEG site metastasis to accurately diagnose and manage the care of this rare occurrence as it is associated with poor prognosis.
