Diagnosis of Thyroid Neoplasm-Associated Dermatomyositis in Ethiopian Woman

Background

Dermatomyositis is an inflammatory myopathies causing proximal muscle weakness accompanied by muscular inflammation and skin rash. Dermatomyositis patients have a higher incidence of malignancy as compared to the general population.

Case Report

A 52-year-old known female patient with a toxic multi-nodular goiter presented with insidious onset of itchy erythematous rash on her neck and bilateral hands and progressive muscle weakness of 4 months' duration. Associated with this, she had photosensitivity, and periorbital edema of 2 months' duration. On physical examination, she had an anterior neck mass, proximal muscle weakness, periorbital edema, and violaceous skin rash on her bilateral arms, shoulders and neck. Thyroid function tests were normal, creatinine kinase was elevated, and muscle biopsy revealed inflammatory myositis. Ultrasound of the anterior neck mass and analysis of fine needle aspiration suggested thyroid cancer.

Conclusion

A high index of clinical suspicion is usually required for early diagnosis of dermatomyositis in resource-limited settings in order to prevent adverse outcomes and identify associated malignancies.

Comparison of Remimazolam versus Sevoflurane on the Postoperative Quality of Recovery in Cervical Spine Surgery: A Prospective Randomized Controlled Double-Blind Trial

Purpose

Remimazolam is a newly developed ultra-short-acting benzodiazepine. We compared overall functional recovery, including the postoperative Quality of Recovery-15 (QoR-15) questionnaire scores, between balanced inhalational anesthesia using sevoflurane and total intravenous anesthesia (TIVA) with remimazolam in patients undergoing anterior cervical discectomy and fusion (ACDF).

Patients and Methods

Seventy-two patients were randomized to the remimazolam (group R) or sevoflurane (group S) group. The primary outcome was the total QoR-15 score on postoperative day (POD) 1. We also assessed the total QoR-15 score on POD2, sub-scores of the QoR-15, perioperative parameters, and postoperative recovery profiles. Group-time interaction effects on the QoR-15 and its sub-scores were analyzed using a linear mixed model.

Results

The total QoR-15 score on POD1 (120.2 in group R vs 114.3 in group S, P=0.189) was not statistically different between the groups. There were no significant group-time interaction effects on total QoR-15 scores. Instead, patients in group R showed significantly better sub-scores in psychological and postoperative nausea and vomiting (PONV) items on POD1, as well as a lower degree of PONV, than those in group S. Among the five dimensions of the QoR-15, a significant group-time interaction effect was observed for psychological support. Group R showed significantly less changeability in blood pressure and heart rate with a lower dose of intraoperatively administered vasopressor than group S.

Conclusion

Considering QoR-15, including PONV reduction, and intraoperative hemodynamic stability, remimazolam can be used as the novel and safe anesthetic agent for maintaining general anesthesia instead of sevoflurane in patients undergoing ACDF.

Nomogram for Estimation of Acute Liver Failure Risk in Spontaneous Ruptured Hepatocellular Carcinoma

Purpose

Acute liver failure (ALF) is a severe complication of spontaneous ruptured hepatocellular carcinoma (SRHCC) that requires accurate prediction for effective treatment strategies. We aimed to develop a predictive nomogram to estimate the risk of ALF in patients with SRHCC undergoing treatment.

Patients and Methods

We performed a retrospective analysis of historical data from 284 patients diagnosed with SRHCC at the First Hospital of Jilin University over the past decade. Variables were selected through univariate and multivariate logistic regression analyses, and a predictive nomogram was constructed. We evaluated its predictive accuracy against the Child-Pugh Score, R.MELD, and ALBI by assessing discrimination, calibration, and net clinical benefit.

Results

Among the 284 patients, 65 developed ALF. The risk factors identified for model development included largest tumor size (LTS), platelet counts, prolonged prothrombin time, and elevated serum α-fetoprotein levels. The nomogram exhibited high accuracy in predicting ALF risk with a C-index of 0.91 (0.87-0.95). The Delong test showed a significant difference between the nomogram and the other three models (p<0.05). The calibration curve for the nomogram fit well, and the decision curve analysis revealed superior net benefit. The optimal cut-off point for the nomogram was determined to be 40, yielding sensitivity, specificity, positive predictive value, and negative predictive value of 83.10%, 87.20%, 65.90% and 94.60%, respectively.

Conclusion

The nomogram we developed provides an optimized tool for predicting ALF in SRHCC patients. Its application can help determine individual patient's risk of ALF, enabling more rational and personalized treatment strategies.

An Extremely Rare Case Report of Aphallia with Horseshoe Kidney and Ureterohydronephrosis

Background

Aphallia (absent penis) is an extremely rare congenital anomaly happening in 1 in 30 million births worldwide. It can occur alone or in combination with other congenital anomalies.

Case Presentation

A two-day-old neonate presented to Arba Minch General Hospital with an absent penis. The delivery was performed at home by a 34-year-old primigravida mother with no antenatal follow-up. As the mother described, the baby cried immediately after birth. The baby was sucking initially but failed to suck hours after delivery. The neonate died of neonatal distress syndrome after two hours of resuscitation.

Conclusion

Aphallia is a complex, extremely rare congenital anomaly that is commonly associated with other congenital anomalies. Sometimes, it may be associated with a lethal anomaly and requires sophisticated workup to diagnose and treat grave anomalies early.

Diagnosis and Management of Cardiovascular Risk in Patients with Polycythemia Vera

Polycythemia vera (PV) is a myeloproliferative neoplasm characterized by aberrant myeloid lineage hematopoiesis with excessive red blood cell and pro-inflammatory cytokine production. Patients with PV present with a range of thrombotic and hemorrhagic symptoms that affect quality of life and reduce overall survival expectancy. Thrombotic events, transformation into acute myeloid leukemia, and myelofibrosis are largely responsible for the observed mortality. Treatment of PV is thus primarily focused on symptom control and survival extension through the prevention of thrombosis and leukemic transformation. Patients with PV frequently experience thrombotic events and have elevated cardiovascular risk, including hypertension, dyslipidemias, obesity, and smoking, all of which negatively affect survival. To reduce the risk of thrombotic complications, PV therapy should aim to normalize hemoglobin, hematocrit, and leukocytosis and, in addition, identify and modify cardiovascular risk factors. Herein, we review what is currently known about the associated cardiovascular risk and propose strategies for diagnosing and managing patients with PV.

Evidence to Date: Clinical Utility of Tremelimumab in the Treatment of Unresectable Hepatocellular Carcinoma

Hepatocellular carcinoma (HCC) is a leading cause of cancer-related deaths worldwide and is associated with significant health care costs and burden. Management of HCC is guided based on the Barcelona Clinic Liver Cancer (BCLC) system and includes liver transplantation, surgical resection, and liver-directed and systemic therapies. In recent years, there have been significant advancements in understanding the immunogenicity of HCC and this has led to approval of different targeted agents as well as immunotherapy for advanced HCC. Tremelimumab is a cytotoxic T lymphocyte-associated antigen-4 (CTLA-4) blocking antibody and has recently been approved in combination with durvalumab (a programmed death-ligand 1 [PDL1] inhibitor) as first-line therapy for advanced (Barcelona Clinic Liver Cancer Stage C) HCC. In this article, we review the different available systemic therapies for advanced HCC with special focus on the clinical utility of tremelimumab for the treatment of unresectable HCC.

Clinical Insight on Proton Therapy for Paediatric Rhabdomyosarcoma

This paper offers an insight into the use of Proton Beam Therapy (PBT) in paediatric patients with rhabdomyosarcoma (RMS). This paper provides a comprehensive analysis of the literature, investigating comparative photon-proton dosimetry, outcome, and toxicity. In the complex and multimodal scenario of the treatment of RMS, clear evidence of the therapeutic superiority of PBT compared to other modern photon techniques has not yet been demonstrated; however, PBT can be considered an excellent treatment option, in particular for young children and patients with specific primary sites, such as the head and neck area (and especially the parameningeal regions), genito-urinary, pelvic, and paravertebral regions. The unique depth-dose characteristics of protons can be exploited to achieve significant reductions in normal tissue doses and may allow an escalation of tumour doses and greater sparing of normal tissues, thus potentially improving local control while at the same time reducing toxicity and improving quality of life. However, access of children with RMS (and more in general with solid tumors) to PBT remains a challenge, due to the limited number of available proton therapy installations.

Credentials That Matter While Selecting a Surgeon for Major Surgical Treatment

Purpose

The credentials of surgeons, which include elements such as medical degree and length of practice, are vital information that forms a perception of their expertise in the patients' minds. The specific credentials that matter to patients and how important they are have not been sufficiently studied. The objective of this study was to assess the relative importance that patients assign to the specific credentials of a surgeon while selecting one for surgical treatment.

Methods

This study was conducted using the constant-variable-value vignette (CVVV) method. Four credentials- medical degrees, duration of practice, medical college attended, and type of surgeries performed - were assessed for their relative importance to patients. The participants were provided with vignettes of medical situations that required major surgical intervention and profiles of surgeons who could perform the required surgery, each dominating the others in a specific credential. The participants allocated a total of 10 points across the four surgeons proportionate to their preferences. The response data were analyzed using descriptive statistics, ANOVA and t-tests.

Results

The highest mean score of 3.73 (SD 2.21) was observed for the surgeon with focused experience, followed by 2.55 (1.57) for the surgeon with the best medical degrees, 2.17 (1.65) for the surgeon with the longest practice experience, and 1.54 (1.47) for the surgeon from a higher-ranked medical college. The mean of the surgeon with focused experience was significantly higher than that of other surgeons, and the mean of the surgeon with the best medical degrees was significantly higher than that of surgeons with the longest practice experience and the surgeon from the topmost medical college (p < 0.05). Preference did not vary with respondents' age or gender.

Conclusion

Patients seem to prioritize the focused surgical experience and superior medical degrees in their selection of surgeons.

The Influence of Diagnosis Intervention Packet Policy Intervention on Medication Structure and Drug Cost of Elderly Hypertensive Inpatients in China: A Multicenter Interrupted Time-Series Analysis

Background

DIP is a new medical insurance payment system developed in China which was implemented in Guangzhou in January 2018, but few studies have focused on its intervention effect on the drug burden of elderly hypertensive patients.

Methods

Nine medical institutions in Guangzhou, China, were selected, among which, daily full medical orders of elderly hypertensive inpatients from 2016 to 2020 were randomly collected. To assess the impact of DIP policy intervention on patient drug burden, we took the data after policy implementation in January 2018, as the intervention data, and applied a segmented regression model with interrupted time series to analyze the trend and changes in average daily drug costs per month and medication structure, stratified by age, sex, and inpatient department.

Results

A total of 34,276 elderly hypertensive patients' daily full medical orders were obtained. The immediate level change of drug costs after intervention was -23.884 RMB/month (P = 0.652), and the trend change was statistically significant (-15.642 RMB/month, P = 0.002). The relative cumulative effect at the end of the study was -78.860% (95% CI: -86.087% to -69.076%), and the intervention effect was more significant in surgical and male patients. The analysis of drug structure changes showed that after the implementation of the DIP policy intervention, the proportion of anti-infective drugs, anti-tumor drugs, and biological products all showed a significant downward trend (P < 0.05), while nutritional drugs showed a significant upward trend (P = 0.011), but no immediate horizontal change in slope was observed.

Conclusion

The typical practice in China showed that DIP policy intervention can improve the drug burden of elderly hypertensive hospitalized patients and has a stable long-term effect, and the intervention effect is not consistent across different clinical department and populations with different characteristics, and it would also cause changes in the medication structure.

Cutaneous Methotrexate-Related Epstein-Barr Virus-Positive Diffuse Large B-Cell Lymphoma in a Patient with Granulomatous Cutaneous T-Cell Lymphoma: A Case Report and Literature Review

Methotrexate-related lymphoproliferative disorders (MTX-LPDs) are immunodeficiency diseases following methotrexate (MTX) administration, mainly occurring in rheumatoid arthritis patients. Although uncommon, MTX-LPDs have been reported in some patients with psoriasis, dermatomyositis, and cutaneous T-cell lymphoma (CTCL) who received MTX. Granulomatous mycosis fungoides (GMF) is a rare subtype of cutaneous T-cell lymphoma, where MTX is one of the treatment options in recalcitrant cases. Herein, we report a case of a 72-year-old female patient with GMF who additionally developed cutaneous Epstein-Barr virus (EBV)-positive diffuse large B-cell lymphoma (DLBCL) during MTX treatment. According to the 5th edition of the WHO classification of Haematolymphoid Tumors (WHO-HAEM), this condition is currently categorized as "lymphoma arising in immunodeficiency/dysregulation". In this article, we also reviewed published literature on cutaneous MTX-LPDs in the setting of CTCL. This entity should be considered in cases of new, atypical skin nodules and/or plaques in CTCL patients receiving long-term MTX treatment.

Assessment of an Epidemic Urgency: Psychometric Evidence for the UCLA Loneliness Scale

Background

In modern industrialized countries, loneliness has been declared an epidemic. The present paper aimed to replicate previous findings about the dimensionality of the UCLA Loneliness Scale-3 version (LS-3) in a sample of Italian adults using Exploratory Structural Equation Modeling (ESEM).

Methods

In Study 1, 1676 participants (M_age= 31.15; SD = 11.89) completed the LS-3. The three-factor ESEM model was performed to replicate the previous Italian version, and a Confirmatory Factor Analysis compared the three- and ten-item short versions. In Studies 2, 3, and 4, we administered measures of anxiety, depression, stress, internet addiction, self-esteem, and social interaction anxiety to 3513 participants (M_age= 30.81; SD = 11.77) to assess the convergent and discriminant validity of LS-3.

Results

The ESEM 3-factor model was replicated using a Target rotation (X² = 847.597; df = 133; CFI = 0.942; TLI = 0.917; RMSEA = 0.062), whereas the already-known LS-3 short version raised psychometric concerns. Positive relationships with anxiety, depression, stress, internet addiction, and social interaction anxiety, as well as negative association with self-esteem were found.

Conclusion

In conclusion, our findings support the use of the LS-3 in the Italian sample and discourage the administration of the current short forms. The implications for research and clinical practice have been discussed.

Outcomes of Radiation Segmentectomy for Hepatocellular Carcinoma in Patients with Non-Alcoholic Fatty Liver Disease versus Chronic Viral Hepatitis

Purpose

To compare the outcomes of radiation segmentectomy for early-stage hepatocellular carcinoma (HCC) in patients with non-alcoholic fatty liver disease (NAFLD) versus hepatitis C virus (HCV).

Materials and Methods

A retrospective analysis of consecutive patients with NAFLD- or HCV-related HCC treated with radiation segmentectomy from 01/2017-06/2022 was performed. Eligibility criteria included solitary tumor ≤8 cm or up to 3 HCC ≤3 cm, ECOG 0-1, and absence of vascular invasion or extrahepatic spread. Imaging best response was assessed per modified Response Evaluation Criteria in Solid Tumors. Target tumor and overall progression, time-to-progression (TTP), and overall survival (OS) were calculated. All outcomes were censored for liver transplantation (LT). Complete pathologic response (CPN) was assessed in patients who underwent LT.

Results

Of 142 patients included (NAFLD: 61; HCV: 81), most had cirrhosis (NAFLD: 87%; HCV: 86%) and small tumors (median size NAFLD: 2.3 cm; HCV: 2.5 cm). Patients with NAFLD had higher BMI (p<0.001) and worse ALBI scores (p=0.003). Patients with HCV were younger (p<0.001) and had higher AFP levels (p=0.034). Median radiation dose (NAFLD: 508 Gy; HCV: 452 Gy) and specific activity (NAFLD: 700 Bq; HCV: 698 Bq) were similar between cohorts. Objective response was 100% and 97% in the NAFLD and HCV cohorts, respectively. Target tumor progression occurred in 1 (2%) NAFLD and 8 (10%) HCV patients. Target tumor TTP was not met for either cohort. Overall progression occurred in 23 (38%) NAFLD and 39 (48%) HCV patients. Overall TTP was 17.4 months (95% CI 13.5-22.2) in NAFLD and 13.5 months (95% CI 0.4-26.6) in HCV patients (p=0.86). LT was performed in 27 (44%) NAFLD and 33 (41%) HCV patients, with a CPN rate of 63% and 54%, respectively. OS was not met in the NAFLD cohort and was 53.9 months (95% CI 32.1-75.7) in the HCV cohort (p=0.15).

Conclusion

Although NAFLD and HCV are associated with different mechanisms of liver injury, patients with early-stage HCC treated with radiation segmentectomy achieve comparable outcomes.

Bibliometric Analysis on Global Analgesia in Labor from 2002 to 2021

Background

Maternal pain during labor is one of the most important factors contributing to increased cesarean delivery rates and poor pregnancy outcomes, and this pain can be managed by labor analgesia. Many studies exist on labor analgesia, and the quantity and quality of these studies have not been reported. Therefore, we aimed to perform a bibliometric analysis of studies from 2002 to 2021.

Methods

We used the Web of Science database to obtain publications related to labor analgesia from January 2002 to December 2021. Various bibliographic information was collected, including country; author; journal; grant; discipline; institution and research hotspot. A total of 4536 papers were included.

Results

A total of 4536 articles were included in the study. The country with the most published articles on labor analgesia and the country of the funding agency was the United States. Most articles were published in the disciplines Anesthesiology and Obstetrics & Gynecology. The journal that published the most articles in this category was International Journal of Obstetric Anesthesia. In addition, we found different research hotspots for labor analgesia in the United States, Japan, and China.

Conclusion

This paper provides a bibliometric analysis of research on labor analgesia and highlights the differences in research hotspots for labor analgesia between countries.

Testicular Tuberculosis: Two Rare Case Report

Tuberculosis is especially common in African countries where HIV is common. Although pulmonary tuberculosis is generally seen, testicular tuberculosis can rarely be seen in young men. Especially in African countries, it is not possible to study acid-resistant bacilli, polymerase-chain reaction and culture due to financial impossibility. For this reason, history, physical examination, scrotal ultrasonography and fine needle biopsy help in diagnosis in suspected cases of testicular tuberculosis. Cure is possible with six months of treatment.

Clinical Efficacy of Interlaminar and Transforaminal Spinal Endoscopy in the Treatment of Lumbar Spinal Stenosis

Purpose

To compare the application effect of interlaminar technique (ILT) and transforaminal technique (TFT) spinal endoscopies in lumbar spinal stenosis (LSS) treatment.

Material and Methods

The data of 46 patients aged 65 years or older diagnosed with LSS between January 2019 and March 2021 were retrospectively reviewed in this study. They underwent ILT (21 patients) or TFT (25 patients) spinal endoscopy surgery, and outcomes were analyzed utilizing the visual analog scale (VAS), Oswestry disability index (ODI), and Japanese orthopedic association (JOA) scale. Lumbar stability was also evaluated using the change in dynamic position X-ray of the spine. We also built three-dimensional (3D) finite element of ILT and TFT spine models and compared them with the stability of the intact spine.

Results

The ILT group had a longer operation time than the TFT group, and patients in ILT and TFT groups had comparable VAS scores for back pain. However, the TFT group had higher VAS scores for leg pain than the ILT group 3, 6 and 12 months postoperatively. The JOA and ODI scores of the 2 groups improved after surgery, and there were statistical differences between the 2 groups at 6 and 12 months follow-up, which proved that functional recovery was better in ILT group. The pre- and postoperative change in dynamic position X-ray of the spine proved that ILT and TFT would not destroy the spine's stability. 3D finite element lumbar spine model analysis also demonstrated this point.

Conclusion

Both ILT and TFT can provide good clinical outcomes; compared with TFT, the ILT approach provided more thorough decompression and was more suitable for treating LSS.

Assessment of Quality of Education in the Case of Bahir Dar Health Science College, Northwest Ethiopia:- A Mixed Method Approach

Introduction

The concept of quality in higher education is highly complex, difficult to define, and multi-dimensional and education is a cornerstone of a nation's development and quality is at the heart of education. Thus, the study aimed to assess the quality of education at Bahir Dar Health Science College, BahirDar, Ethiopia, 2021.

Methods

A mixed method approach was employed from May 1- June 30, 2021. Systematic random sampling and purposive sampling methods were used to collect quantitative and qualitative data respectively. Self-administered questionnaires and in-depth key informant interviews were conducted. The data were analyzed via stata 14 and presented by descriptive frequencies and tables. Thematic analysis was employed for qualitative data.

Results

Most instructors 26 (59.1%) are not satisfied with library services and 33 (75%) of them did not conduct a research project or participate in any community services. The findings also stated that the college has made its level best to improve the quality of education via the implementation of continuous assessment, active learning approach, remedial and affirmative action and training. Regarding students, half of them 166 (50.6%) are not comfortable with the college environment. Students were also greatly grouchy the services delivered in the college such as cafeteria, dormitory, student clinic and guidance and counseling.

Conclusion

The study found out that there is a relatively low level of satisfaction among both groups and the quality of education is below the acceptable level. Therefore, the college should create an opportunity to engage in national and regional networks to share best practices in quality education and it requires the office to develop the capacity of their services.

A Patient with Adalimumab-Induced Refractory Paradoxical Palmoplantar Pustulosis Was Successfully Treated by Ixekizumab: A Case Report

Ankylosing spondylitis (AS) is a chronic immune-mediated inflammatory disorder involving the sacroiliac (SI) joints, the spine and often the hips. Biologic therapy has been shown to be efficacious in patients with AS and could improve patients' quality of life. With the increased use of tumor necrosis factor-ɑ (TNF-ɑ) inhibitors, more paradoxical reactions have been revealed. However, the treatment option for patients with AS is still a challenge when refractory paradoxical palmoplantar pustulosis appeared after the use of TNF-ɑ inhibitors. We reported the case of a 45-year-old male patient with AS treated with adalimumab treatment who developed a refractory paradoxical palmoplantar pustulosis after failure of prior secukinumab treatment. A dramatic improvement was seen in all skin and low back pain after the use of ixekizumab. We conclude that, in TNF-α inhibitors induced refractory paradoxical palmoplantar pustulosis, ixekizumab should be considered as an alternative option to choose from.

Prenatal Diagnosis of Retinoblastomas: A Scoping Review

Purpose

The objective of this review is to explore the prenatal diagnosis of retinoblastoma and the recommended screening practices.

Patients and Methods

An electronic literature search on prenatal diagnosis of retinoblastoma was conducted on the PubMed database. Publications within the last 20 years that matched the inclusion criteria were selected. The literature search included the following keywords: retinoblastoma, prenatal, diagnosis, screening, and associated synonyms to increase search sensitivity. Nine studies were included for investigation and extracted to identify prenatal diagnostic and screening techniques for retinoblastoma, their associated impact, and the target population that should receive prenatal screening for retinoblastoma.

Results

Familial retinoblastoma has an autosomal inheritance pattern and 90% penetrance. Therefore, future parents with a family history of retinoblastoma are strongly advised to get tested for retinoblastoma (Rb) gene mutations; if one of the parents is positive for a mutated allele of the RB1 gene, there is a 45% chance that their child will inherit a mutated allele of the retinoblastoma gene, rendering the allele non-functional in all of the cells of the individual and predisposing the child to a higher risk of developing retinoblastoma as well as other secondary cancers. Thus, prenatal screening and diagnosis of retinoblastoma is crucial for early diagnosis and optimal treatment.

Conclusion

Prenatal testing for retinoblastoma in high-risk families is important for everyone in the family. For the parents, prenatal screening has been shown to improve their family planning decisions and psychological well-being as they can mentally prepare beforehand and make informed decisions. More importantly, these practices have shown to yield better treatment and vision outcomes in the newborn.

Presence of Hepatocellular Carcinoma Does Not Affect Course and Response to Anticoagulation of Bland Portal Vein Thrombosis in Cirrhotic Patients

Background

Malignancies are generally considered a risk factor for deep vein thrombosis and may hamper the recanalisation of thrombosed veins.

Aim

We investigate whether the natural course and response to anticoagulant treatment of bland portal vein thrombosis (PVT) in patients with cirrhosis complicated by hepatocellular carcinoma (HCC) differ from those without HCC.

Methods

Retrospective study in two hepatology referral centres, in Italy and Romania where patients with a diagnosis of PVT on cirrhosis and follow-up of at least 3 months with repeated imaging were included.

Results

A total of 162 patients with PVT and matching inclusion and exclusion criteria were identified: 30 with HCC were compared to 132 without HCC. Etiologies, Child-Pugh Score (7 vs 7) and MELD scores (11 vs 12, p=0.3679) did not differ. Anticoagulation was administered to 43% HCC vs 42% nonHCC. The extension of PVT in the main portal trunk was similar: partial/total involvement was 73.3/6.7% in HCC vs 67.4/6.1% in nonHCC, p=0.760. The remainder had intrahepatic PVT. The recanalization rate was 61.5% and 60.7% in HCC/nonHCC in anticoagulated patients (p=1). Overall PVT recanalisation, including treated and untreated patients, was observed in 30% of HCC vs 37.9% of nonHCC, p=0.530. Major bleeding incidence was almost identical (3.3% vs 3.8%, p=1). Progression of PVT after stopping anticoagulation did not differ (10% vs 15.9%, respectively, HCC/nHCC, p=0.109).

Conclusion

The course of bland non-malignant PVT in cirrhosis is not affected by the presence of active HCC. Treatment with anticoagulation in patients with active HCC is safe and as effective as in nonHCC patients, this can potentially allow us to use otherwise contraindicated therapies (ie TACE) if a complete recanalization is achieved with anticoagulation.

Pharmaceutical Care Within Community Pharmacies: Tools Availability and Pharmacists' Views, Wad-Medani, Sudan

Background

Pharmaceutical Care (PhC) services within community pharmacies (CPs) have become a vital issue in many developed countries.

Purpose

This study assessed the availability of PhC tools and pharmacists' views towards PhC services within CPs in Sudan.

Methods

A cross-sectional study was conducted from December 2019 to August 2020 using a pretested self-administered questionnaire. The participants were 120 community pharmacists.

Results

Fifty-eight percent of respondents used to work in pharmacies near homes rather than within the marketplace. The study revealed that the overall tool availability of the assessed components and items was only 25% (Counselling areas 3%, Records 5%, Pharmacist identity 3%, Pharmacy phones 15%, Medical devices 38%, and Staff 29%). The result of pharmacists' views towards the PhC concept, roles, and responsibilities showed a high level of agreement, at 88%, with a statistically insignificant difference between participants.

Conclusion

Tools available within CPs were lower than required. However, pharmacists' views showed a high agreement level towards PhC concept roles and responsibilities. Community pharmacists, academic sectors, and regulatory authorities must start initiatives to improve the provision of PhC tools for better patient care service delivery.

Facial Demodicosis-Induced Skin Hyperpigmentation in an Immunocompromised Man Treated Successfully with Ivermectin 1% Cream: A Case Report

Demodex folliculorum is a common ectoparasite of humans that inhabits follicular infundibulum and sebaceous ducts. Its role in various dermatological diseases is well studied. However, data on demodex-induced skin pigmentation are very limited. A diagnosis of this entity can be easily missed for other causes of facial hyperpigmentation such as melasma, lichen planus pigmentosus, erythema dyschromicum perstans, post-inflammatory hyperpigmentation, and drug-induced hyperpigmentation. Here, we report a case of facial demodicosis-induced skin hyperpigmentation in a 35-year-old Saudi male who is on multiple immunosuppressive agents. He was successfully treated with ivermectin 1% cream and had a dramatic improvement at his 3-month follow-up. Our aim is to shed light on this underdiagnosed cause of facial hyperpigmentation which can be easily diagnosed and followed up by bed side dermoscopic examination and managed effectively by anti-demodectic therapies.

All-Arthroscopic Refixation of an Osteochondral Femoral Avulsion of the Anterior Cruciate Ligament with a Laxity-Minimizing Suture

Purpose

Torn anterior cruciate ligaments in children are rare injuries. The incidence of concomitant avulsion fracture in the skeletally immature patient is high. Reports of arthroscopic reconstruction in the literature are sparse.

Case Presentation

We present the case of a femoral avulsion fracture of the anterior cruciate ligament in a seven-year-old girl. The patient underwent arthroscopic refixation with Dynacord^TM Suture and Suture Button. At a follow-up of 8 weeks, the patient had free range of motion and a stable knee, with a negative Lachman- and Pivot-Shift-test in particular.

Conclusion

Refixation of femoral avulsion fracture can lead to good results. Open physes and size of the knee should be taken into account. Anatomic reconstruction is compulsory to receive bone on bone healing.

Mortality and Deep Vein Thrombosis in the Gamma Variant of Covid 19 and Lung Injury

PURPOSE

The SARS-CoV-2 disease predisposes infected individuals to thrombosis, the underlying mechanisms of which are not fully understood. The balance between pro-coagulant factors and natural coagulation inhibitors in critically ill patients with Covid-19 is fundamental to the prevention and treatment of complications. The aim of the present study was to investigate the pulmonary injury patterns in Covid-19 having higher mortality in the presence of deep vein thrombosis in comparison to patients without venous thrombosis and determine the Gamma variant.

METHODS

A retrospective study was conducted involving the evaluation of 200 medical records of patients with Covid-19 and a clinical suspicion of deep vein thrombosis (DVT) at the intensive care unit of a public hospital. The sample was divided into two groups of patients were formed - those positive and those negative for DVT. Statistical analysis involved the use of Fisher's exact test, the paired t-test and chi-square test.

RESULTS

Patients with DVT had more severe lung injuries (greater than 70%) compared to those without DVT (p = 0.003). Lesions affecting 50% to 70% of the lung area occurred in little more half of the group with DVT and just under half in the group without DVT (p = 0.5). Pulmonary lesions affecting less than 50% of the lung occurred more in patients without DVT (p = 0.0001). The Gamma variant increased prevalence of the both DVT and mortality (p=0.0001).

CONCLUSION

Deep vein thrombosis is an aggravating factor of mortality in patients with SARS-CoV-2, and the Gamma variant is an aggravating factor of both thrombotic events and mortality.

Extent of Utilization of Radiologic Images in Gross Anatomy Teaching, the Experience of Ethiopian Medical Schools

BACKGROUND

One of the greatest developments in modern medicine is the strides taken in radiology. Today, thanks to high-tech devices like computer tomography (CT), magnetic resonance imaging (MRI), and ultrasound, a noninvasive glimpse into the human interior has been made possible. These recent developments have revolutionized how doctors see anatomy. To keep pace with this progress, many medical school anatomy curriculums have undergone a facelift. In these new curriculums, radiology has been presented as a practical and sufficient alternative tool for learning anatomy. This study, therefore, aimed to determine the extent of the use of radiologic images in the teaching of anatomy in Ethiopian medical schools.

METHODS

An online questionnaire was used to collect, compile and analyze data from anatomy instructors in Ethiopian medical schools.

RESULTS

The survey showed that 55.9% of the instructors used radiologic images of one form or another in their teaching. However, it also revealed radiological images comprise <5% of the total images used in teaching. The majority (73.5%) of the instructors lacked any prior training or coursework in radiologic anatomy. Despite full-time radiology faculties existing in the schools, a relationship between the anatomy and radiology department is virtually unheard of.

CONCLUSION

The curriculum currently in use in Ethiopian medical schools is designed in a way both vertical and horizontal integration of the traditional subjects are achieved. This way, the introduction of clinical medicine early will provide context and relevance to the learning of basic science. Despite the curriculum's emphasis, we have observed limitations in the degree of integration of anatomy and radiology.

A Scoping Review on the Status of Female Breast Cancer in Asia with a Special Focus on Nepal

This study aimed to provide updated evidence on the status of female breast cancer and cancer treatment facilities in Asia, with a special focus on Nepal. This review used search phrases that included, breast neoplasm or cancer, health status, epidemiology, breast cancer survivors, cancer care facilities, Asia, Nepal. Researchers examined databases from January 2011 to December 2020 (PubMed, PMC, Google Scholar, and the reference lists of included papers). Studies of any design and reviews, were included in the study, except for qualitative studies. The study findings are presented in a narrative synthesis format using Preferred Reporting Items for Systematic Reviews and Meta-analyses Extension for Scoping Reviews. An initial search resulted in 974 papers, and 896 were reviewed after being checked for duplication using the Zotero software. Accordingly, utilizing the inclusion and exclusion criteria, 188 publications were selected, and after review of titles and abstracts, an additional 98 papers were removed for different reasons. Finally, the study looked at 90 female breast cancer papers. Results showed that the number of cases of breast cancer is growing all around the world, including in Asia and Nepal. Age, early menarche, late menopause, nulliparity, positive family history, excessive fat consumption, alcohol, and smoking are all frequent risk factors for breast cancer found in Asian women. Breast self-examination, clinical breast examination, and mammography screening are common methods for detecting breast carcinoma. Chemotherapy, radiation, and modified mastectomy are commonly used options for treatment. The number of breast cancer survivors is growing throughout the world, indicating better clinical care. There is a paucity of survival data in many Asian countries, including Nepal. There is also a scarcity of health workforce specialized in cancer care and treatment, as well as a few health facilities that are available to treat cancer cases in many Asian countries, including Nepal.

Synthesis, In Silico and Pharmacological Evaluation of New Thiazolidine-4-Carboxylic Acid Derivatives Against Ethanol-Induced Neurodegeneration and Memory Impairment

Introduction

Several studies revealed that alcohol utilization impairs memory in adults; however, the underlying mechanism is still unclear. The production of inflammatory markers and reactive oxygen species (ROS) plays a major role in neurodegeneration, which leads to memory impairment. Therefore, targeting neuroinflammation and oxidative distress could be a useful strategy for abrogating the hallmarks of ethanol-induced neurodegeneration. Moreover, several studies have demonstrated multiple biological activities of thiazolidine derivatives including neuroprotection.

Methods

In the current study, we synthesized ten (10) new thiazolidine-4-carboxylic acid derivatives (P1-P10), characterized their synthetic properties using proton nuclear magnetic resonance (¹H-NMR) and carbon-13 NMR, and further investigated the neuroprotective potential of these compounds in an ethanol-induced neuroinflammation model.

Results

Our results suggested altered levels of antioxidant enzymes associated with an elevated level of tumor necrosis factor-alpha (TNF-α), nuclear factor-κB (p-NF-κB), pyrin domain-containing protein 3 (NLRP3), and cyclooxygenase-2 (COX-2) in ethanol-treated animals. Ethanol treatment also led to memory impairment in rats, as assessed by behavioral tests. To further support our notion, we performed molecular docking studies, and all synthetic compounds exhibited a good binding affinity with a fair bond formation with selected targets (NF-κB, TLR4, NLRP3, and COX-2).

Discussion

Overall, our results revealed that these derivatives may be beneficial in reducing neuroinflammation by acting on different stages of inflammation. Moreover, P8 and P9 treatment attenuated the neuroinflammation, oxidative stress, and memory impairment caused by ethanol.

How Do Clinical Supervisors and Managers in Swedish Primary Care Perceive Their Opportunities to Meet the Learning Needs of Medical Students?

INTRODUCTION

Primary health care centers (PHCCs) in Sweden are struggling to maintain a balance between increasing demands of service and supervision and learning activities for a growing number of students. We sought a deeper understanding of primary care physicians and managers behavioral intention towards supervising, and their perceptions of the structural preconditions and support needed.

METHODS

The study combines two theoretical approaches, the Theory of Planned Behavior (TPB) and Social Practice Theory. A questionnaire with 22 items including an open-ended question was designed to collect quantitative and qualitative data and sent to clinical supervisors and managers at PHCCs in Southern Sweden. The aim was to map a) participants' behavioral intention and perceived capacity to act to improve supervision and b) their perceptions of structural prerequisites and support needed to sustain and develop clinical supervision practice.

RESULTS

A total of 181 questionnaires were returned, with a total response rate of 60.7%. Behavior predictors (attitudes, subjective norms, and perceived behavioral control) were positively correlated to behavioral intention towards supervising and building supervising competence. Three themes emerged from the content analysis of the qualitative data: "Time and distribution", "Improved communication and support systems" and "Elimination of structural barriers.".

DISCUSSION

The manager and supervisor reports suggest that the intentions and capacity of individuals (individuals' agency) is not a strong barrier to high-quality supervising and teaching in PHCC. Organizational preconditions for sustaining and developing supervision practice exist, and structural barriers for exercising agency could be eliminated according to PHCC managers and supervisors. However, a conclusion of our study from a practice theory perspective is that how and to what degree primary care physicians engage in supervision and competence building is determined by how the workplace - and the medical school - afford participation in supervision-related workplace activities. Improved communication between medical school, managers and supervising physicians and on-site faculty development integrated in daily clinical work were described as important facilitators of a favorable supervision and learning environment.

An Innovative Site-Specific Anti-HER2 Antibody-Drug Conjugate with High Homogeneity and Improved Therapeutic Index

Purpose

Antibody-drug conjugates (ADCs) have emerged as a potent cancer therapeutic option in recent years. DP303c is a HER2-targeting ADC with a cleavable linker-MMAE payload. The current study aimed to evaluate the therapeutic potentials of DP303c in vitro as well as in vivo.

Materials and Methods

Size exclusion chromatography (SEC), reverse-phase high-performance liquid chromatography (RP-HPLC), and liquid chromatography-tandem mass spectrometry (LC-MS/MS) were used to analyze the physicochemical characterization of DP303c. An enzyme-linked immunosorbent assay (ELISA), a cell-based assay, and bio-layer interferometry (BLI) were used to evaluate DP303c’s affinity with HER2 and Fc receptors. A confocal laser scanning microscopy was used to observe the internalization of DP303c. Antibody-dependent cell-mediated cytotoxicity (ADCC) and cytotoxicity assays were used to investigate the activity of DP303c in vitro. The antitumor activity of DP303c was assessed in vivo in the HER2-positive cell-derived xenograft model.

Results

DP303c was a site-specific anti-HER2 antibody-drug conjugate with a monomethyl auristatin E (MMAE) with an average drug-to-antibody ratio (DAR) of 2.0. DP303c showed a high affinity with HER2 and could be effectively internalized. In vitro and in vivo, DP303c showed stronger antitumor activity as compared to trastuzumab-DM1 (T-DM1) in a series of HER2-positive cancer cells and cell-derived xenograft (CDX) models, especially in the lower HER2-expressing cells. DP303c also exhibited high serum stability and a good PK profile.

Conclusion

DP303c was a steady and homogenous DAR 2 ADC that was predicted to deliver MMAE inhibitor to tumor cells. DP303c demonstrated remarkable anticancer efficacy against T-DM1 in xenograft models. DP303c was a strong candidate for the treatment of patients with HER2-positive cancer.

Prevalence and Determinants of Antibiotic Self-Administration Among Adult Antibiotic Users: A Cross-Sectional Study

INTRODUCTION

Each year, antibiotics save hundreds of thousands of lives; nonetheless, antibiotic self-administration is a major concern all over the world. This study aimed to investigate the prevalence of antibiotic self-administration among two-month adult antibiotic users as well as the factors contributing to this prevalence.

METHOD AND PARTICIPANTS

This cross-sectional study was conducted among 295 Bangladeshi adults between May 22nd and June 15th, 2021, during the COVID-19 pandemic. Descriptive statistics included frequency distribution, while inferential statistics included the Pearson chi-square test. For data analysis, the statistical software STATA-16 was used.

RESULTS

In this study, the prevalence of antibiotic self-administration was 17.97%. Antibiotic self-administration was found to be significantly more prevalent among those who were unable to take antibiotic on time, incomplete doses, did not know over prescriptions may cause antibiotic resistance, and could not correctly recognize amoxicillin and azithromycin are antibiotics.

CONCLUSION

Due to the increased rate of antibiotic self-administration among adults in Bangladesh, the responsible authority should give more attention towards the factors responsible for antibiotic self-administration and revise their current policy to ensure the safe and effective use of antibiotics.

The Survival Status and Predictors of Mortality Among Stroke Patients at North West Ethiopia

INTRODUCTION

Stroke is one of the commonest non-communicable disease types that has a great public health impact both in developed and developing countries. However, in Ethiopia, the long-term survival status of stroke patients is not very understood. This study aimed at assessing survival status and predictors of mortality among stroke patients at Felege Hiwot comprehensive specialized hospital from September 1, 2014, to August 31, 2019, Bahirdar, North West Ethiopia.

METHODS

An institutional-based retrospective cohort study was conducted using 368 registered stroke patients between September 1, 2014, and August 31, 2019. We used Kaplan-Meier together with a Log-rank test to compare the survival rate of the study participants using categorical variables and to compare covariate and both bi-variable and multivariable Cox proportional hazards regression analysis model was conducted to identify predictors of mortality among stroke patients. The association between outcome and independent variables was expressed using an adjusted hazard ratio (AHR) with a 95% confidence interval and statistical significances were declared at P-value of <0.05.

RESULTS

Fifty-six (15.2%) of the 368 stroke patients included in the study died, and 312 (84.8%) were correctly censored. The overall survival rate was 72.2% at 51 months of follow-up with a median survival time of 0.26 months. Age greater than 65 (AHR 6.31, 95% CI 1.75-22.74), body temperature >7.1 degree centigrade (AHR = 7.14, 95% CI: 2.76-18.5), potassium level below <2 mmol/l (AHR = 2, 95% CI: 1.9-23.53) and creatinine level >1.2 mg/dl (AHR = 7.85, 95% CI: 2.7-22.6) were predictive predictors of mortality.

CONCLUSIONS

In the follow-up of 51 months, significant mortality occurred. Important predictive predictors of survival status were identified. Interventions should be focused on health education and awareness creation of the community for the early management of stroke.

The Prevalence and Clinical Features of Skin Irritation Caused by Infection Prevention Measures During COVID-19 in the Mecca Region, Saudi Arabia

PURPOSE

Due to the COVID-19 pandemic, recommendations to prevent infection suggest increasing the frequency of handwashing and disinfection; however, these measures can have negative implications on our skin. This study aims to evaluate whether these measures correlate with new-onset skin damage or can exacerbate hand eczema among the general population.

MATERIALS AND METHODS

This was a descriptive, cross-sectional, survey-based study, including the general population of Mecca region, Saudi Arabia. To achieve the study's aim, an online questionnaire to the general population comprising 25 items was distributed via social media apps during the pandemic between October 23 and November 21, 2020. Data were automatically collected in Excel and entered into SPSS for analysis.

RESULTS

A total of 783 participants were included in this study, of whom 695 (88.8%) were female. A history of hand eczema was reported among 123 (15.7%) participants, and 270 (34.5%) had a history of atopy. During the COVID-19 pandemic, 86 (13.0%) participants noticed new-onset skin irritation, while 81 (31.3%) of the participants reported exacerbation of earlier hand allergic dermatitis. The most frequent symptoms were dryness and feeling of tightness. Additionally, most participants among both groups noticed that skin lesions appeared for less than 10 days. The frequent handwashing statistically increased following the onset of the pandemic (p=0.001), there is association between new-onset symptoms and more frequent handwashing, as well as the use of hand disinfectants, during the pandemic (p=0.001).

CONCLUSION

Our study suggests that the general population's skin was negatively affected by COVID-19 precautions, particularly those with a history of hand eczema. We recommend spreading awareness of skin protective modalities and the use of new infection prevention measures, such as regular skin moisturization for hand protection and possibly using less damaging skin disinfectants like ozonized water provided it is scientifically proven effective in disinfecting COVID-19 virus.

Adverse Gastrointestinal Effects with Kayexalate or Kalimate: A Comprehensive Review

BACKGROUND

Patients with hyperkalemia are commonly treated with Kayexalate or Kalimate. Both drugs are associated with some fatal gastrointestinal (GI) adverse events (AEs).

AIM

To assess the clinical characteristics and outcomes of GI AEs induced by Kayexalate or Kalimate from published case reports.

METHODS

We conducted a systematic review of case reports of Kayexalate or Kalimate-induced GI AEs, from PubMed, Medline, Cochrane Library, Clinical Key, and Google Scholar databases (1948 to March 31, 2020). We analyzed the clinical characteristics, GI AEs, and risk factors of enrolled patients.

RESULTS

We identified 41 published articles describing 135 cases of GI AEs induced by Kayexalate (103 cases) or Kalimate (32 cases). The mean age of all patients was 55.5 years. Most patients were male (54.8%). As high as 55.6% preparations were administered with sorbitol whereas 44.4% preparations had no sorbitol. The average time causing GI AEs was 19.8 days. Colon was the most commonly affected site (76.3%). Drug crystals were histopathologically proven in 95.5% of the patients. Meanwhile, mortality was reported in 20.7%.

CONCLUSION

Kayexalate or Kalimate, without or with sorbitol combination, may be related to fatal GI damage. Uremia, hypertension, and transplantation are predisposing factors. Clinicians should be careful in prescribing Kayexalate or Kalimate to patients.
