Dynamic interplay between corticosteroid treatment and the role of SRC-1 gene dysregulation in the progression of WHO-Grade 4 Astrocytoma.

BACKGROUND: Corticosteroid is commonly used before surgery to control cerebral oedema in brain tumours and is frequently continued throughout treatment. Its long-term effect of on the recurrence of WHO-Grade 4 astrocytoma remains controversial. The interaction between corticosteroid, SRC-1 gene and cytotoxic T-cells has never been investigated. METHODS: A retrospective cohort of 36 patients with WHO-Grade 4 astrocytoma were examined for CD8 + T-cell and SRC-1 gene expressions through IHC and qRT-PCR. The impact of corticosteroid on CD8+T-cells infiltration, SRC-1 expression, and tumour recurrence was analyzed. RESULTS: The mean patients age was 47-years, with a male to female ratio 1.2. About 78% [n = 28] of the cases showed reduced or no CD8+T-cell expression while 22% [n = 8] of cases have showed medium to high CD8+T-cell expression. SRC-1 gene was upregulated in 5 cases [14%] and 31 cases [86%] showed SRC-1 downregulation. The average of total days and doses of administered corticosteroid from the preoperative period to the postoperative period was at range of 14-106 days and 41-5028 mg, respectively. There was no significant statistical difference in RFI among tumours expressing high or low CD8+T-cells when corticosteroid was administered in recommended or exceeded doses [p-value = 0.640]. There was a significant statistical difference in RFI between CD8+T-Cell expression and SRC-1 gene dysregulation [p-value = 002]. Tumours with high CD8+T T-cell expression and SRC-1 gene downregulation had late recurrence. CONCLUSIONS: Corticosteroid treatment can directly affect the SRC-1 gene regulation but does not directly influence cytotoxic T-cells infiltration or tumor progression. However, SRC-1 gene downregulation can facilitate late tumor recurrence.

Outcomes after laser interstitial thermal ablation for temporal lobe epilepsy: a systematic review and meta-analysis.

Epilepsy is a common condition that affects approximately 1% of the world's population, with about one-third being refractory epilepsy. Temporal lobe epilepsy is the most common type of drug-resistant epilepsy, and laser interstitial thermal therapy (LITT) is an innovative treatment. In this systematic review and meta-analysis, we aimed to summarize the current evidence on outcomes after LITT, including seizure freedom rate, complication rate, and neurocognitive outcome. PubMed and OVID Medline search engines were systematically searched for all indexed publications in the English language up to July15, 2023. The search was limited to human studies. Proportions and 95% confidence interval (CI) values were calculated for seizure, neurocognitive outcome, and complication rate. A total of 836 patients were included. Overall seizure outcomes, regardless of the pathology, included Engel I outcome in 56% (95% CI, 52.4-59.5%), Engel II outcome in 19.2% (95% CI, 15.4-23.6%), Engel III outcome in 17.3% (95% CI, 13.5-21.8%), and Engel IV outcome in 10.5% (95% CI 6.3-17%) of the patients. The overall decline in verbal and visual memory regardless of laterality was 24.2 (95% CI 8.6-52%) and 25.2% (8.3-55.8%). For naming, the decline was 13.4% (6.6-25.4%). The results of the pooled analysis in comparison with available data in the literature showed that seizure outcomes after LITT were slightly inferior to published data after temporal lobectomy. Data on cognitive outcomes after LITT are scarce and heterogeneous.

Systemic Review: Neurological Deficits following Ventriculoperitoneal Shunt (VPS) Insertion.

A reduction in fluid absorption or an obstruction of normal outflow is a common cause of hydrocephalus. It typically requires medical attention, which frequently entails the placement of a ventriculoperitoneal shunt (VPS) to lower intracranial pressure. We intend to list the few, documented examples of neurological impairments resulting from the installation of a VPS in this systematic study. Two search engines (PubMed and Cochrane) were used to conduct a systematic review from 1975 to December 12, 2021. The following search terms were employed: neurological deficits or neurological injury or palsies or thalamus or tract or longitudinal fasciculus or somatotropy or fasciculus or hearing loss or hemisensory or cortico AND ventriculoperitoneal shunt or VPS AND hydrocephalus. The inclusion criteria included VPS, neurological deficits, and human participants. The exclusion criteria included ventriculoarterial shunt, lumboperitoneal shunt, nonhuman subjects, and infection. Twenty trials in total, including a total of 25 patients, were included. There were 17 case report studies. A total of 35/785 patients (4.46%) experienced neurological impairments. In 9/25 (36%) of shunt cases had one of the three recognized causes: trapped fourth ventricle, dandy walker, or syringomyelia. Most of the patients developed VI, VII nerve palsies 11/25 (44%) followed by weakness, cerebellar symptoms, and VI nerve palsy. The brainstem was seen to be the most often injured structure (15/25; 60%), followed by deep brain structures (thalamus, basal ganglia, and white matter tracts; 20%). Even though ventriculoperitoneal shunting is a routine and straightforward treatment, issues can still arise. Although rare, there have been reports of cranial nerve impairments, therefore care should be taken.

Major Histocompatibility Class-I (MHC-I) downregulation in glioblastoma is a poor prognostic factor but not a predictive indicator for treatment failure.

BACKGROUND: MHC-I expression is a crucial factor in cancer immunity, and its regulations can impact tumor progression and recurrence. The mechanism through which glioblastoma use MHC-I to avoid immunosurveillance has been rarely investigated. METHODS: A retrospective cohort of 35 patients with IDH-mutant WHO-Grade 4 astrocytoma and IDH-wildtype glioblastoma were examined for MHC-I using protein and gene expression assays. The association between IDH mutation, TP53 mutation, and MHC-I expression with recurrence-free interval were investigated. RESULTS: The average patients' age was 49.6 year. IDH was wildtype in 13 tumors. MHC-I protein expression was absent in 30 tumors, faint in 4 tumors, and membrane bound dense expression in single tumor. MHC-I expression was upregulated in 10 tumors and 25 tumors showed MHC-I downregulation. P53 was positively expressed in 19 cases and lost in 13 cases. A significant statistical difference was observed in the RFI between tumors with distinct MHC-I expression and IDH-mutation [p-value = 0.008]. IDH-wildtype tumors with upregulated MHC-I expression showed late tumor recurrence compared to IDH-wildtype tumors with downregulated MHC-I expression. There was insignificant statistical difference in RFI among patients with varying degree of MHC-I expression, who received TMZ or TMZ and other chemotherapies [P-value = 0.44] CONCLUSIONS: Glioblastoma with upregulated MHC-I showed a delayed tumor recurrence in comparison to those with downregulated MHC-I expression. However, downregulated MHC-I may not necessarily be an indicator of poor problems.

Optic Pathway-Hypothalamic Glioma Apoplexy: A Report of Two Cases and Systematic Review of the Literature.

Background: Hemorrhage into optic pathway-hypothalamic glioma (OPHG) is rare. Variable clinical presentations and outcomes are associated with such pathology. We aim to present two infants presented with OPHG and a systematic review of the literature. Methods: We describe two cases of infants presenting with sudden decreased vision, poor feeding, and irritability due to OPHG. Both patients underwent urgent craniotomy and subtotal resection followed by chemotherapy. We systematically reviewed the literature using PubMed, Google Scholar, and Embase. In addition, we included all English published reports for all ages discussing the optic pathway (optic nerve and optic chiasm) or hypothalamic glioma associated with hemorrhage from the year of the first reported case (1970) to January 2022. Results: Of 17,949, 44 articles met the inclusion criteria of this review. A total of 56 cases were described with a mean of 21.35 years (0.5-70), with the male gender 52% and the female gender 45%. The hemorrhage location was sellar/suprasellar in 43% cases. Histopathology of included cases was pilocytic astrocytoma in 41%, followed by pilomyxoid astrocytoma in 16% cases. The outcome was unfavorable; 37.5% cases showed improvement, whereas 18% cases resulted in death. Conclusion: Apoplexy of the OPHG can be fatal and associated with poor outcomes. A systematic review of the literature has shown that younger age, pilocytic or pilomexyoid astrocytoma histopathology, and chiasmal/hypothalamic locations are associated with a higher risk of intertumoral hemorrhage and poor prognosis. Further genetic studies for OPHG may provide information for high-risk patients.

Hemisensory Loss after Ventriculoperitoneal Shunt Insertion.

Idiopathic intracranial hypertension includes ventriculoperitoneal shunt (VPS) insertion, with a reported complication of shunt revision in 25% of the cases 1 year after insertion. We report a case of a 28-year-old female with pituitary adenoma who developed sensory loss after VPS placement that could be explained by disruption in thalamic pathways. A lesson learned from this case is that although VPS is a simple procedure, complications can occur. Modalities can be used to detect the complications, and further revisions might be needed.

Complicated appendicitis increases the hospital length of stay.

Background: There are insufficient data from Saudi Arabia regarding appendectomy outcomes and hospital length of stay. Further, there is a need to compare the length of stay of Saudi patients and the literature. The purpose is to evaluate the surgical outcomes and hospital length of stay for complicated appendicitis and simple appendicitis. Method: This is a single-center retrospective review of patients who had undergone an appendectomy between 2016 and 2018. The patients were divided into 2 groups: complicated appendicitis versus simple appendicitis. Results: Of 449 patients who underwent appendectomy, 60 (13.4%) had complicated appendicitis. The complicated appendicitis was significantly associated with increased age, pain duration, neutrophilia, high C-reactive protein, fecalith presence, and free fluid. The incidence rate of surgical site infection was 5.8% (identified in 26 patients). Compared to simple appendicitis, complicated appendicitis was associated more with wound infection (1.8% vs 10%, respectively, P = .001), postoperative collection (1.2% vs 11.6%, respectively, P = .001), and readmission within 30 days (2.3% vs 13.4%, respectively, P = .001). By multivariate analysis, factors associated more with increased hospitalization were pain duration (hazard ratio = 2.37, 95% confidence interval = 1.09-5.16, P = .029), operative time (hazard ratio = 2.09, 95% confidence interval = 1.04-4.21, P = .038), and complicated appendicitis (hazard ratio = 6.61, 95% confidence interval = 2.67-14.21, P = .001). Conclusion: Complicated appendicitis correlates with significant morbidity, readmission rate, and 6 times more hospital LOS than simple appendicitis. This review might help in appreciating the burden of complicated appendicitis on hospital length of stay, which needs allocating patients and planning the discharge day for hospitals with limited beds.

Pancreatic Carcinoid Tumor in a Pediatric Patient.

BACKGROUND Carcinoid tumors are well-differentiated tumors that develop from neuroendocrine cells. They are rare tumors and occur most commonly in the gastrointestinal tract, followed by the pulmonary system. They usually present with abdominal pain or cough or persistent pneumonia. They are usually diagnosed with computed tomography (CT) or magnetic resonance imaging (MRI) of the chest or abdomen. The cornerstone of treatment is surgical resection. There are rare reported cases of carcinoid tumor presenting in the pancreas as gastrinoma or insulinoma and are associated with multiple endocrine neoplasia type 1 (MEN1). CASE REPORT We report a case of an otherwise healthy 9-year-old girl who presented with manifestations of Cushing syndrome (easy fatigability, weakness, back pain, easy bruising, hirsutism, acne, skin discoloration [pigmentation], and blurred vision). She was diagnosed with incidental carcinoid tumor in the pancreas based on hypertension and typical stigmata. She underwent distal pancreatectomy and splenectomy. The histopathology showed a well-differentiated neuroendocrine tumor with G2. The diagnosis of concurrent Cushing syndrome and carcinoid syndrome can be challenging, as it is rare. It is important to screen for MEN syndrome when Cushing syndrome occurs in a child, as there is a high rate of transition to malignancy. They are usually diagnosed with ACTH, cortisol, and imaging. CONCLUSIONS Incidental hypertension in children is not common and mandates further investigation and clinical work-up to look for endocrinopathies such as Cushing syndrome and carcinoid syndrome. As the literature on such cases is scant, further reporting of cases is needed.

Recent Technical Developments in the Field of Laparoscopic Surgery: A Literature Review.

The benefits of laparoscopic surgery (LS) include a speedy recovery, shorter duration of hospital stay, minimal postoperative pain, discomfort and disabilities, and better cosmetic outcomes (less scarring) that help an individual to resume normal daily activities and return to work. A comprehensive literature search on laparoscopic surgeries was conducted using different Internet-based search engines and databases from August 2021 to October 2021. The search was limited to articles published in the English language and those published between years 2005 and 2021. A total of 126 articles were initially identified. Two independent reviewers thoroughly examined the quality and content of the articles. Articles with duplicate data were excluded, and the remaining articles were screened and assessed by the titles and abstracts. After a vigorous assessment, we included data from 49 articles for this review process. Bibliographic management was done using the software "EndNote" (Thomson Reuters, New York, NY, USA). It was concluded that LS has become the technique of choice for virtually every kind of abdominal surgery, evident by numerous scholarly publications in this field. Level I evidence demonstrating the advantage of LS over open surgery has been reported for numerous operations, including fundoplication for gastroesophageal regurgitation disease, bariatric surgery for weight loss, and cancer resection. Advanced LS has subsequently been expanded to include hepatectomy, pancreatectomy, urology, and gynecology. Patients who are at risk of having elevated abdominal pressure during LS, however, should proceed with care. Recent advances in natural orifice transluminal endoscopic surgery, single-incision laparoscopic surgery, and robot-assisted laparoscopic surgery are promising.

Simple approach for the histomolecular diagnosis of central nervous system gliomas based on 2021 World Health Organization Classification.

The classification of central nervous system (CNS) glioma went through a sequence of developments, between 2006 and 2021, started with only histological approach then has been aided with a major emphasis on molecular signatures in the 4th and 5th editions of the World Health Organization (WHO). The recent reformation in the 5th edition of the WHO classification has focused more on the molecularly defined entities with better characterized natural histories as well as new tumor types and subtypes in the adult and pediatric populations. These new subclassified entities have been incorporated in the 5th edition after the continuous exploration of new genomic, epigenomic and transcriptomic discovery. Indeed, the current guidelines of 2021 WHO classification of CNS tumors and European Association of Neuro-Oncology (EANO) exploited the molecular signatures in the diagnostic approach of CNS gliomas. Our current review presents a practical diagnostic approach for diffuse CNS gliomas and circumscribed astrocytomas using histomolecular criteria adopted by the recent WHO classification. We also describe the treatment strategies for these tumors based on EANO guidelines.

Multiple lessons learned from a single case: Complications from pineal germinoma management.

BACKGROUND: Pineal tumors are uncommon tumors that affect <1% of adults, with 50% of them being germinomas. A combination of endoscopic third ventriculostomy (ETV) and tumor biopsy is usually used. Cerebral vasospasm in association with aneurysmal subarachnoid hemorrhage (aSAH) has been extensively studied. However, at least according to the research, this is not the case in intraventricular hemorrhage (IVH) cases. We present a case with two distinct findings: (1) an unexpected large IVH following the removal of an external ventricular drain (EVD) in a patient who had undergone ETV and tumor biopsy, resulting in severe clinical vasospasm and (2) incidental pineal region germinoma regression on follow-up magnetic resonance imaging (MRI) without any prior adjuvant chemoradiation to explain such regression. CASE DESCRIPTION: The authors describe an 18-year-old male patient who had a routine, uneventful combined ETV and tumor biopsy, as well as the placement of an EVD. Histopathological examination revealed germinoma. His postoperative course was complicated by IVH after EVD removal, which resulted in clinical vasospasm. Without any prior adjuvant chemoradiation, follow-up MRI of the b rain revealed a significant reduction in the size of the germinoma as well as reconstitution of the patency of the previously obstructed aqueduct of Sylvius. CONCLUSION: The take-home message from this case is that in the case of postoperative clinical deterioration in a patient with concurrent IVH and ETV, a high index of suspicion for vasospasm is required, as this may allow a significant amount of blood to pass down to the basal cisterns. Early detection and management of clinical vasospasm are critical for a better neurological outcome. Furthermore, unexpected tumor size changes can occur due to a variety of factors, so recent preoperative MRI of the brain should be obtained in the lead-up to surgery, and postoperative computed tomography should be used sparingly to avoid radiation-related tumor changes.

Immunolocalization of neurokinin 1 receptor in WHO grade 4 astrocytomas, oral squamous cell and urothelial carcinoma.

INTRODUCTION: Neurokinin-1 receptor (NK-1R) induces inflammatory reactions in peripheral tissues but its regulatory effects in target tissues is dependent on receptor signalling. Substance P (SP) has a high affinity for the NK-1R, to which it binds preferentially. We aimed to investigate the expression of NK-1R in World Health Organization (WHO) grade 4 astrocytomas as well as in oral squamous cell carcinoma (OSCC) and urothelial carcinoma, and its association with disease progression. MATERIAL AND METHODS: The study included tissue samples from 19 brain astrocytomas, 40 OSCCs and 10 urothelial carcinomas. NK-1R expression was quantitatively assessed in the tumour cells using immunohistochemistry. The relationship between NK-1R expression in astrocytomas and recurrence-free interval has been explored. RESULTS: The results showed that the NK-1R was intensely expressed in patients with WHO grade 4 astrocytoma, OSCC and urothelial carcinoma. However, cases clinically diagnosed as a low-grade cancer showed reduced NK-1R expression. CONCLUSIONS: NK-1R is overexpressed in all cases of WHO grade 4 astrocytoma, OSCC and urothelial carcinoma. The ubi-quitous presence of SP/NK-1R complex during tumour development and progression suggests a possible therapeutic key strategy to use NK-1R antagonist as an adjuvant therapy in the future.

Epidural Abscess Following Epidural Evacuation in a Patient With Ventriculoperitoneal Shunt: A Case Report.

Epidural abscess is considered one of the most common intracranial infections. We report a pediatric patient with chronic hematopoiesis and thick double periosteal layers who developed an epidural pus collection after epidural hematoma evacuation. This article highlights the importance of detecting complications from epidural hematoma evacuation, including intracranial abscess and pus formation. Therefore, it is crucial to treat such cases meticulously.

Cerebellar Mutism Treated Successfully With Zolpidem in a Patient With Learning Difficulties.

Posterior fossa tumors constitute the most common brain tumor in pediatrics with 25% development postresection. Cerebellar mutism can manifest as neurobehavioral abnormalities that can occur within days to months after surgery but usually peak on the third postoperative day. It can be caused by discontinuation of dento-thalamo-cortical pathway in the vermian lesion, due to edema, tumors, and hypoperfusion. We report a seven-year-old patient with posterior fossa lesion (pilocytic astrocytoma in histopathology) and learning difficulties with symptoms of urinary retention, pseudobulbar palsy, and motor incoordination that were treated successfully with zolpidem 2.5 mg with regain of function by the third month.

Intradural Extramedullary Lesions in the Cervical Spine in Neurofibromatosis.

BACKGROUND Neurofibromatosis (NF) is categorized into 3 diseases: neurofibromatosis type 1, type 2, and schwannoma. NF2 is associated with a mutation in gene 22q11.2. It is present in about 1/25 000 to 33 000 births, and it is passed in an autosomal dominant fashion. Diagnosis is made based on clinical and radiological features. A few clinical features have been characterized and included in the Manchester criteria. A few neurofibromatosis type 2 patients have been diagnosed with over 25 cervical lesions. We report a case of an intradural extramedullary cervical lesion in a patient later diagnosed with neurofibromatosis type 2. CASE REPORT The patient was 30-year-old man admitted through the emergency unit, presenting with gradual onset and progressive spastic quadriparesis of 6 months duration. An MRI spine showed intradural extramedullary masses in the right side of C4 and left side of C6. He underwent cervical intradural excision of 2 masses under general anesthesia with neuromonitoring. The tumor was sent to histopathology and reported as neurofibromatosis 2. CONCLUSIONS Neurofibromatosis is a common entity, but the diagnosis of a cervical mass is judicious to avoid any misfortune in neurological function. It requires a multidisciplinary approach and screening modalities.

Case Report: Surgical Management in Acute Subdural Hematoma Induced by Chronic Myelogenous Leukemia.

BACKGROUND Chronic subdural hematoma is defined as collection in the subdural space for more than 3 weeks. The incidence ranges from 1 to 20 per 100 000/year, with increased prevalence in the elderly, in males, and with use of anticoagulants or antiplatelets. Chronic myeloid leukemia has been linked to spontaneous subdural hematoma, with the highest reported cases of 39 patients in Korea, but no management is mentioned in that paper. There are few reported cases of patients who are medically free with no use of anticoagulants, diagnosed as having a subdural hematoma and then later discovered to have chronic myelogenous leukemia. CASE REPORT We report the case of a 45-year-old man, with known hypertension and diabetes mellitus type 2, on aspirin weekly, who was referred from another hospital with a history of sudden-onset severe headache not related to trauma. Computed tomography (CT) of the brain done in the other hospital showed a left-side subdural hematoma with midline shift. He underwent left-sided acute subdural hematoma evacuation and decompressive hemicraniectomy. He was started on hydroxyurea for chronic myelogenous leukemia. CONCLUSIONS A lesson from this rare case is to look for a differential diagnosis and to keep chronic myelogenous leukemia in mind in patients with leukocytosis. Also, we recommend sending a hematology referral in nontraumatic subdural hematoma. There is no specific treatment or algorithm based on previous research, although from observed data and based on information from the American Heart Association, it is reasonable to perform craniectomy in extra-axial collections of more than 1 cm with midline shift to avoid mortality, as reaching a diagnosis would take too much time.

Perception, Academic Performance, Gender Judgment and Barriers among Surgeons' Career Progression in Jeddah, Saudi Arabia: A Cross-Sectional Study.

INTRODUCTION: Gender discrimination continues to be an issue in different surgical subspecialties, especially in Saudi Arabia, where no studies have been conducted so far on female surgeons in academia, on gender discrimination, and on job satisfaction. Considering the increasing number of women enrolling for surgery programs in Jeddah, Saudi Arabia, this study aims to examine their perceptions about and equity in working as surgeons. METHODS: Following the STROCSS criteria, cross-sectional analyses were conducted of survey data from a multicentric online questionnaire in 2019/2020. A representative sample of medical interns and surgeons (n = 100) from Saudi Arabia responded out of 400 from the 4th iteration. RESULTS: Females were 53%; most participants were less than 40 years. Women ranked assistant professors were fewer than men (2% vs. 11%). The number of publications by females vs. males was 2.58 +/- 2.68 vs. 11.37 +/- 20.53 (p = 0.002). Surgery was not considered a profession conducive to family life according to more than half the women citing lack of flexible/part-time training or work (26/53, or 49%). However, only 1/5, or 9/47 (19.1%), of men thought there was gender attitude/bias; men also had more variety in surgical career choices. Further, most patients preferred male surgeons ( p = 0.026). Both females (30/53 or 56.6%) and males (25/47 or 53.2%) agreed that the best response to an offensive question was to ignore it. Decision in choosing their specialty was influenced mostly by career and promotion prospects, enthusiasm, and commitment (females: 31/53 or 58.5% and males: 17/47 or 36.2%) with p = 0.026. CONCLUSIONS: The findings reveal the persisting discrepancies based on gender in the surgical field in Saudi Arabia. A nationwide movement limiting working hours, encouraging medical students to enter surgery, and upholding women in leadership positions can help in overcoming this situation.

Analysis of 190 Female Patients after Appendectomy.

This study is a retrospective cohort review carried out at a single, private tertiary center. We included 190 female patients who underwent surgery for acute appendicitis between January 2016 and December 2018. Two groups of patients were analyzed based on the pregnancy. The main outcome measures were complication rate and risk of abortion during or after surgery. Out of 190 female patients, eight of them were pregnant (4.2%). The pregnant group more significantly underwent ultrasound investigation compared to the nonpregnant group. Complicated appendicitis present in two pregnant patients at advanced gestational age was not statistically significant from nonpregnant. Laparoscopic appendectomy was performed in 6/8 (75%) of pregnant compared to 158/182 (87%) in nonpregnant (p = 0.415). Compared to the nonpregnant, the pregnant group has a more fecolith, positive peritoneal fluid culture, and wound infection, with E. coli more frequently isolated in 25%. None of the pregnant patients had an abortion, preterm labor, or mortality during or after surgery. In conclusion, laparoscopic appendectomy is a low-risk operation for pregnant with acute appendicitis.

Pain Management in Breast Cancer Patients: A Multidisciplinary Approach.

Pain is a significant problem and is one of the most invalidating symptoms in breast cancer (BC) patients that would negatively affect the functional status and the Quality of Life (QoL). Pain management in BC patients requires thorough patient evaluation and critical assessment of pain. The actual cause for the pain must be recognized, so management can be tailored to each patient. This review aims to discuss various treatment modalities employed for effectively managing pain in BC patients. Pharmacotherapy makes up the cornerstone of the management of pain in BC patients. Both opioid and non-opioid analgesics are utilized. The WHO recommends a method called "by the ladder" for managing pain in BC patients where analgesics are used in ascending order. In comprehensive pain management (CPM), non-pharmacologic therapies are gaining wide acceptance and popularity, including complementary and alternative medicine (CAM), procedural and psychosocial interventions. Procedural interventions are usually used in case of severe pain refractory to pharmacological therapy. Techniques, such as radiotherapy, neurectomy, and nerve blocks, are effective in managing cancer pain. However, CAM therapies in BC pain management need to be guided by enough scientific evidence, decision-making, and medical judgment of regulatory bodies. BC pain management is based on careful routine pain assessments and appropriate patient evaluation both physically and psychologically. Pain control is one of the methods to improve the QoL of BC patients. Both pharmacological and non-pharmacological therapies are accessible to patients today, but they should be used with caution to minimize toxicity and increase effectiveness. The use of any pain management intervention should be based on proper scientific evidence and collective medical judgment.

Knowledge and attitudes towards Zika virus among medical students in King Abdulaziz University, Jeddah, Saudi Arabia.

Zika Virus (ZIKV) and its associated consequences remain vital public health challenge of international concerns. The current study was done to assess knowledge and attitudes towards ZIKV and the factors associated with good knowledge among medical students in King Abdulaziz University, Jeddah. A cross-sectional study was conducted among 426 students. They were selected through multistage stratified random sample method, 2016. A validated, confidential, interviewing questionnaire contained 25 knowledge and 10 attitude items was used. Descriptive and inferential statistics were done. Results revealed that Facebook was the commonest source of ZIKV information. About half of the participants correctly identified mosquito bites and vertical route as ZIKV transmission modes. However, smaller percentages recognized the sexual and blood transmission modes. Calculations of knowledge score revealed that 77.5%, 15.0%, and 7.5% of the participants obtained poor, fair, and satisfactory scores, respectively. Age, educational year and attending ZIKV training were significantly associated with good knowledge (p<0.05). Concerning attitudes, about half of the participants agreed that ZIKV could add new burden on healthcare system of the affected countries. Most of participants were interested in learning more about ZIKV, emerging diseases and travel epidemiology. In conclusion, medical students had limited knowledge about ZIKV, and good attitudes towards learning about it. Conduction of ZIKV educational programs, and development of courses about emerging disease epidemiology are required.
