Revision Lumbar Spine Surgeries: An Early Career Neurosurgery Experience.

BACKGROUND: The aims and ambitions of a surgeon in the early years of his professional career are to make a good reputation by providing excellent patient outcomes and avoiding complex and difficult surgeries. Revision lumbar spine surgeries (RLSSs) pose a significant challenge in terms of surgical management, as the moribund anatomy increases the risk of complications, adding to an unlikely outcome. OBJECTIVE: We conducted this study to determine the clinical indications and outcomes of RLSSs performed by an early career neurosurgeon. MATERIALS AND METHODS: This cross-sectional study was conducted after approval from the hospital's ethical committee, and data was collected in late December of 2022 and early January 2023, from retrospective records for a single early career neurosurgeon. A form was filled with each patient's data, such as age, gender, time since surgery, indication for surgery, operative findings, types of surgery performed, etc. All variables were noted for the patient and were further categorized, based on the clinical records, into many sub-categories. RESULTS: Almost 400 lumbar spine surgeries were performed by the surgeon, and about 45 (11.25%) were revision surgeries, and the full record was available for 42 surgeries. These patients' ages ranged from 22 to 70 years, and the mean age was about 46.74±13.29 SD. The common symptoms leading to revision surgeries were numbness and pain in 17 (40.5%) patients each; common per-operative findings were recurrent disc in eight patients (19%), infection in nine patients (21.4%), and fibrosis/adhesions in 16 (38.1%); most common surgeries performed were diskectomy in 11 (26.2%) and diskectomy plus release of adhesions in 12 (28.6%); complications occurred in 14 (33%), and good to excellent outcomes was recorded in 29 (69%) cases.  Conclusion: RLSSs are difficult compared to first-time lumbar spine surgeries, and the moribund anatomy predisposes to complications, and better shall be dealt with great care and, at the minimum, shall be embarked upon as a team.

Arrhythmias and Device Therapies in Cardiac Amyloidosis.

Cardiac amyloidosis is caused by amyloid fibrils that deposit in the myocardial interstitium, causing restrictive cardiomyopathy and eventually death. The electromechanical, inflammatory, and autonomic changes due to amyloid deposition result in arrhythmias. Atrial fibrillation is by far the most common arrhythmia. The rate control strategy is generally poorly tolerated due to restrictive filling physiology and heart rate dependance, favoring adoption of the rhythm control strategy. Anticoagulation for stroke prophylaxis is warranted, irrespective of CHA2DS2-VASc score in patients with a favorable bleeding profile; data on left appendage closure devices are still insufficient. Ventricular arrhythmias are also not uncommon, and the role of implantable cardioverter-defibrillator in cardiac amyloidosis is controversial. There is no evidence of improvement in outcomes when used for primary prevention in these patients. Bradyarrhythmia is most commonly associated with sudden cardiac death in cardiac amyloidosis. Pacemaker implantation can help provide symptomatic relief but does not confer mortality benefit.

Emerging Horizons in the Diagnosis of Pancreatic Cancer: The Role of Circulating microRNAs as Early Detection Biomarkers for Pancreatic Ductal Adenocarcinoma.

Pancreatic ductal adenocarcinoma (PDAC) is a highly aggressive cancer with a poor prognosis, primarily due to a late diagnosis. Recent studies have focused on identifying non-invasive biomarkers for early detection, with microRNAs (miRNAs) emerging as promising candidates. This systematic review aims to evaluate the potential of circulating miRNAs as biomarkers for the early detection of PDAC, analyzing their diagnostic accuracy, specificity, and sensitivity. Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, a comprehensive search across PubMed, Embase, and the Cochrane Library was conducted. Studies published from January 2013 to October 2023 focusing on miRNA biomarkers for early PDAC detection were included. Data synthesis was performed through a narrative approach due to the heterogeneity of the studies. Nine studies met the inclusion criteria. Key findings include the elevated levels of specific miRNAs, such as miR-18a, miR-106a, and miR-25, in early-stage PDAC patients compared to controls. The integration of miRNA profiles with traditional biomarkers like CA19-9 showed improved diagnostic performance. However, challenges in the standardization of miRNA evaluation methodologies were noted. Circulating miRNAs demonstrate significant potential as non-invasive biomarkers for early PDAC detection. Despite promising results, further research and standardization are necessary for clinical application.

Incidence of infection in carpal tunnel surgery with and without the use of local antibiotics.

Objectives: To compare the infection rate in patients who underwent carpal tunnel surgery with and without instilling local antibiotics into the surgical wound. METHODS: The retrospective cohort study was conducted at the Department of Surgery, Unit of Neurosurgery, Government Naseer Ullah Babar Memorial Hospital, Peshawar, Pakistan, and comprised data from July 2019 to July 2021 related to non-diabetic patients without any comorbidity who had undergone fresh carpal tunnel surgery. The cases had been operated by two surgeons having a different approach to preventing infection in carpal tunnel surgery cases. The surgeon in group A did not use any local antibiotics after completing the surgery, while the surgeon in group B instilled local gentamicin in the open wound for 3 minutes after completing the nerve release. All patients were put on oral antibiotics for a period of 5 days after the procedure in both the cohorts, and were assessed fortnightly for any infection and removal of stitches. Demographics of the patients, use of antibiotics and the occurrence of infection were recorded on a proforma. Data was analysed using SPSS 20. RESULTS: Of the 177 patients operated during the period, 13(7.3%) were discarded owing to missing data. Of the 164(92.7%) patients analysed, 138(84.14%) were females and 26(15.85%) were males. The overall mean age was 32.46±8.97 years. The total surgeries conducted were 176; 96(54.54%) in group A and 80(45.45%) in group B. Infections were found in 3(1.7%) patients; all in group A (p=0.160). CONCLUSIONS: Although not statistically significant, instillation of local antibiotics may play a role in preventing surgical site infections in carpal tunnel surgery cases.

Harmonizing Medicine and Surgery in the Pursuit of Boolean Remission: A Rheumatological Magnum Opus.

Rheumatic diseases encompass a diverse group of musculoskeletal conditions that often lead to inflammation, pain, and significant limitations in patients' lives. While traditional treatment approaches have primarily centered on medications to control symptoms, recent developments have introduced the concept of Boolean remission. Boolean remission offers a comprehensive evaluation of disease activity by considering clinical, biochemical, and patient-reported outcomes. This narrative review explores the multifaceted landscape of Boolean remission in the context of rheumatic diseases, with a focus on rheumatoid arthritis (RA), as it remains a substantial clinical challenge. The review outlines the definition, criteria, historical context, and development of Boolean remission, shedding light on its emergence as a more patient-centered and stringent treatment goal. The role of pharmacological interventions, including immunomodulators and biologics, in achieving Boolean remission is discussed, emphasizing the significance of treatment protocols that encompass regular monitoring, medication adjustment, shared decision-making, and patient education. Surgical interventions, such as joint replacements and synovectomies, complement medication-based strategies when joint damage becomes severe, with adherence to surgical protocols ensuring sustained Boolean remission. The integration of medicine and surgery through integrated care models and interdisciplinary teams is examined as a critical aspect of optimizing patient outcomes. Boolean remission's broader impact on healthcare policies and clinical trial endpoints is explored, underscoring its growing significance in rheumatic disease management. The review concludes by looking toward the future, where emerging technologies, biomarkers, and personalized medicine approaches hold promise in refining Boolean remission criteria and making it a more attainable and impactful treatment goal. Policy implications suggest the integration of Boolean remission into healthcare quality metrics, incentivizing healthcare providers to prioritize this rigorous standard of care. Boolean remission represents a pivotal shift in the holistic and patient-centered management of rheumatic diseases, offering hope for improved patient outcomes and enhanced quality of life in this challenging clinical landscape.

Calcifying Nested Stromal-Epithelial Tumor: An Extremely Rare Hepatic Tumor.

Calcifying nested stromal-epithelial tumor is a rare hepatic malignancy with approximately 50 cases reported in the literature. Its clinical presentation is nonspecific, and the diagnosis is mainly based on histology which shows nests of spindle and epithelioid cells along with a desmoplastic myofibroblastic stroma containing variable calcification and ossification. In this report, we present a case of a 24-year-old woman with a history of abdominal pain, distension, and dyspepsia. She had a palpable liver with normal liver function test results. Serum alpha-fetoprotein levels were within normal range, and serologies for hepatitis B and C virus remained negative. Radiological investigations (magnetic resonance imaging and computed tomography) showed a large, right hepatic lobe mass with tumor invasion into the right posterior portal vein, but the 2 modalities could not characterize the lesion. Finally, an ultrasound-guided biopsy of the liver lesion provided the diagnosis of calcifying nested stromal-epithelial tumor. The tumor was resected successfully.

Epithelioid hepatic angiomyolipoma in pregnancy: A case report.

INTRODUCTION AND IMPORTANCE: Epithelioid hepatic angiomyolipoma (HAML) is a rare benign tumor predominantly found in women. Its occurrence during pregnancy is extremely rare. Accurate diagnosis of HAML is challenging due to its radiological resemblance to other hepatic neoplasms. We present a case of epithelioid HAML in a pregnant patient, highlighting the diagnostic and management challenges encountered. CASE PRESENTATION: A 24-year-old pregnant female, in her fifth month of pregnancy, presented with right hypochondrium pain and nausea. Radiological imaging suggested the possibility of a hepatic adenoma. The patient opted to continue the pregnancy with regular monitoring of the mass as well as fetal health. After delivering a healthy baby, the patient underwent successful mass excision and cholecystectomy. Histopathology of the liver mass confirmed the diagnosis of epithelioid HAML. CLINICAL DISCUSSION: Epithelioid HAML is a rare tumor often misdiagnosed. It is more aggressive and frequently associated with tuberous sclerosis complex (TSC) compared to other subtypes. The diagnosis of HAML can be challenging due to its resemblance to Hepatocellular Carcinoma and other hepatic neoplasms on radiological imaging. Immunohistochemistry plays a crucial role in confirming the diagnosis. Surgical excision is the recommended treatment, with complete removal to minimize the risk of recurrence. CONCLUSION: This case report highlights the rarity of epithelioid HAML during pregnancy and emphasizes the importance of a multidisciplinary approach in managing hepatic neoplasms. Close monitoring is crucial, considering the potential risks to the mother and fetus. Accurate diagnosis through histopathological evaluation, immunohistochemistry and a multidisciplinary approach are essential for appropriate management.

Synthesis and biological evaluation of carboxamide and quinoline derivatives as P2X7R antagonists.

P2X7 receptor (P2X7R) has a key role in different pathological conditions, importantly overexpressed and activated in cancers. We explored the structure activity relationship (SAR) of three novel pyrazines, quinoline-carboxamide and oxadiazole series. Their selective inhibitory potency in Ca2+ mobilization assay using h-P2X7R-MCF-7 cells improved with phenyl ring substitutions (-OCF3, -CF3, and -CH3) in carboxamide and oxadiazole derivatives, respectively. However, highly electronegative fluoro, chloro, and iodo substitutions enhanced affinity. 1e, 2f, 2e, 1d, 2 g and 3e were most potent and selective toward h-P2X7R (IC50 values 0.457, 0.566, 0.624, 0.682, 0.813 and 0.890 µM, respectively) and were inactive at h-P2X4R, h-P2X2R, r-P2Y6R, h-P2Y2R, t-P2Y1R expressed in MCF-7 and 1321N1 astrocytoma cells. Cell viability (MTT assay at 100 µM, cell line) for 3e was 62% (HEK-293T), 70% (1321N1 astrocytoma) and 85% (MCF-7). >75% cell viability was noted for 2 g and >80% for 2e and 1d in all non-transfected cell lines. Anti-proliferative effects, compared to control (Bz-ATP), of selective antagonists (10 µM) were 3e (11%) 1d, (19%) 1e, (70%, P = 0.005) and 2f, (24%), indicating involvement of P2X7R. Apoptotic cell death by flow cytometry showed 1e to be most promising, with 35% cell death (PI positive cells), followed by 2e (25%), 2f (20%), and 1d (19%), compared to control. Fluorescence microscopic analysis of apoptotic changes in P2X7R-transfected cell lines was established. 1e and 2f at 1X and 2X IC50 increased cellular shrinkage, nuclear condensation and PI/DAPI fluorescence. In-silico antagonist modeling predicted ligand receptor interactions, and all compounds obeyed Lipinski rules. These results suggest that pyrazine, quinoline-carboxamide and oxadiazole derivatives could be moderately potent P2X7R antagonists for in vivo studies and anti-cancer drug development.

Donor Safety First: Postoperative Hepatectomy Outcomes in Living Liver Donors.

BACKGROUND: Living donor liver transplantation (LDLT) has become a popular treatment option because some countries lack a deceased organ program and the growing demand for liver transplants. Although postoperative outcomes are similar to deceased donor liver transplants, there is still an element of risk to the donor. The Clavien-Dindo classification system has been used to standardize reporting across different institutions and surgeons to categorize surgical outcomes. METHODS: Between January 1, 2022, and December 31, 2022, 207 living donors underwent hepatectomies at our center. All donors underwent a 3-step process of mandatory screening. Postsurgical complications were classified using the Clavien-Dindo classification. RESULTS: A total of 207 donor hepatectomies for LDLT were performed during our study period. Most donors (92.8%) were aged between 18 and 39 years. The most common type of graft used was a right lobe without the middle hepatic vein (82.6%). Most donors (91.7%) experienced an intraoperative blood loss of ≤500 mL. A total of 140 patients had an ordinary postoperative course. Grade 1 complications were observed in 16.9%, grade 2 in 12.1%, and grade 3 in 3.4% of the remaining patients. No grade 4 or grade 5 (patient death) complications were observed in this cohort. CONCLUSIONS: Living donor liver transplantation remains the most practiced liver transplant surgery in Pakistan. Our findings highlight the safety of the LDLT program with minimal risk of significant complications. The study also underscores the importance of careful screening and monitoring of living donors and the need for standardized reporting of surgical outcomes using the Clavien-Dindo classification system.

Exploring safety and efficacy of rivaroxaban after living donor liver transplantation: a retrospective study.

PURPOSE: Thromboembolic complications remain a significant concern in postoperative patients, particularly those who have undergone liver transplantation. Warfarin has been the standard oral anticoagulant. Direct oral anticoagulants (DOACs) have several advantages over warfarin, including rapid onset of action and standardized dose guidelines. We aimed to assess the safety of rivaroxaban in living donor liver transplantation (LDLT) recipients. METHODS: This study was a single-center, retrospective descriptive analysis of LDLT recipients who received rivaroxaban between December 2020 and April 2022. A total of 27 recipients received rivaroxaban postoperatively. Liver function tests, immunosuppression levels, serum creatinine, and INR were recorded before the initiation of rivaroxaban and then on post-therapy days 1, 7, 14, 28, 90, and 180. RESULTS: Among the 27 recipients receiving rivaroxaban postoperatively, portal venous thrombosis was the most prevalent indication for anticoagulation (44.4%), followed by Budd-Chiari syndrome (29.6%). Nine patients had a twofold increase in either ALT or AST values, two of whom were treated for biliary strictures and the others for rejection. Eighteen patients were given tacrolimus, and eight were on cyclosporine, with one patient switched from tacrolimus to cyclosporine due to insufficient therapeutic levels. There were no incidents of bleeding or re-thrombosis during the 180-day follow-up period. CONCLUSION: Rivaroxaban may be a safe and effective alternative in LDLT recipients with no significant adverse incidents. Further studies with larger sample sizes are needed to confirm these findings and determine this population's optimal dose and duration of rivaroxaban therapy.

Bradyarrhythmias in Cardiac Amyloidosis and Role of Pacemaker.

Cardiac amyloidosis (CA) is an underdiagnosed disease that is caused by deposition of misfolded transthyretin (ATTR) or immunoglobulin light chain (AL) fibrils in the myocardium. Bradyarrhythmias are commonly seen in CA, due to disruption of conducting system by amyloid fibrils. Atrioventricular conduction defect is more common than sinus node dysfunction. Bradyarrhythmias are most prevalent in wtATTR, followed by hATTR and AL. Pacemaker implantation, when indicated, can help provide symptomatic relief but does not confer mortality benefit. Progression of conduction system disease is common and often leads to increased right ventricular pacing burden with time. Therefore, cardiac resynchronizing therapy (biventricular therapy) is often considered as a better and safer option in these patients. Finally, the role of prophylactic pacemaker implantation is controversial, and current guidelines do not recommend prophylactic pacemaker insertion in CA patients.

Prevalence of ventricular arrhythmias and role of implantable cardioverter-defibrillator in cardiac amyloidosis.

Cardiac amyloidosis is an underdiagnosed disease that is caused by myocardial deposition of misfolded light chain (AL) or transthyretin (ATTR) amyloid fibrils, leading to restrictive cardiomyopathy and eventually death if untreated. Ventricular arrhythmias are common in cardiac amyloidosis, and the prevalence is higher in AL than ATTR. There are multiple suspected pathogenic mechanisms for ventricular arrhythmia including activation of inflammatory cascade from direct amyloid deposition, and electro-mechanical as well as autonomic dysfunction due to systemic amyloid deposition. Cardiac amyloidosis is associated with an increased risk of sudden cardiac death, and the risk is higher in AL than ATTR. Finally, the role of implantable cardioverter-defibrillators in cardiac amyloidosis is controversial, and while successful termination of life-threatening ventricular arrhythmias has been reported in few studies, there has been no evidence of improvement in outcomes when used for primary prevention in patients with cardiac amyloidosis.

Differential Regulation of Innate Lymphoid Cells in Human and Murine Oral Squamous Cell Carcinoma.

Oral squamous cell carcinomas (OSCC) remain a major healthcare burden in Asian countries. In Pakistan alone, it is the most common cancer in males and second only to breast cancer in females. Alarmingly, treatment options for OSCC remain limited. With this context, investigations made to explore the inflammatory milieu of OSCC become highly relevant, with the hope of practicing immunotherapeutic approaches to address this highly prevalent tumor. We investigated the newly identified innate lymphoid cells (ILCs) and associated cytokines in well-defined human oral squamous cell carcinoma (OSCC) as well as in a 7,12-dimethylbenz[a]anthracene (DMBA)-induced murine model of OSCC using flow cytometry and quantitative real-time polymerase chain reaction (qPCR). We further went on to explore molecular circuitry involved in OSCC by developing a murine model of OSCC and using an α-Thy1 antibody to inhibit ILCs. Amongst the ILCs that we found in human OSCC, ILC3 (23%) was the most abundant, followed by ILC2 (17%) and ILC1 (1%). Mice were divided into four groups: DMBA (n = 33), DMBA+antibody (Ab) (n = 30), acetone (n = 5), and control (n = 5). In murine OSCC tissues, ILC1 and ILC3 were down-infiltrated, while ILC2 remained unchanged compared to controls. Interestingly, compared to the controls (DMBA group), mice treated with the α-Thy1 antibody showed fewer numbers of large tumors, and a larger percentage of these mice were tumor-free at this study's end point. We present novel data on the differential expansion/downsizing of ILCs in OSCC, which provides a pivotal basis to dive deeper into molecular circuitry and the OSCC tumor niche to devise novel diagnostic, therapeutic, and prognostic strategies to prevent/treat oral cancers.

The Prevalence of Bunions in the Setting of Brachymetatarsia.

Brachymetatarsia is caused by premature closure of the physis and is characterized by a short metatarsal. Additional foot conditions may exist in patients presenting with brachymetatarsia, such as hallux valgus (HV). A retrospective study was performed to evaluate the prevalence of HV and brachymetatarsia in the ipsilateral foot. Ninety-seven feet with congenital brachymetatarsia were reviewed in a multi-study cohort of 66 patients who underwent surgical correction between January 2005 and August 2020 at a single institution. The group was comprised of 61 females and 5 males, with a mean age of 27 years. HV deformities were verified with standardized anteroposterior radiographs. HV was present in 29 of 97 feet for a prevalence of 30% in the feet with brachymetatarsia. Our results demonstrate a 30% prevalence of HV associated with brachymetatarsia. This information is helpful for foot and ankle surgeons managing brachymetatarsia to determine appropriate conservative or surgical management of this condition.

The Role of the Shortened Proximal Phalanx in the Setting of Brachymetatarsia.

Brachymetatarsia is a condition in which a metatarsal bone does not grow out to full length. This is caused by premature physeal closure. The proximal phalanx associated with the shortened metatarsal helps achieve the natural parabola of the foot. A hypoplastic proximal phalanx is a common finding in patients with brachymetatarsia. The goal of this study was to determine the length of the proximal phalanx in the setting of brachymetatarsia, and how much the shortening is attributed to the clinically smaller toe. We performed a retrospective study to evaluate the length of the proximal phalanx in the shortened ray. After the metatarsal was brought out to the desired length of correction, the proximal phalanx was measured on radiographs. Ninety-seven feet with congenital brachymetatarsia were reviewed in a cohort of 66 patients who underwent surgical correction between January 2005 and February 2020 at a single institution. The group was comprised of 61 females and 5 males, with a mean age of 27.5 years. The average length of the proximal phalanx associated with the affected metatarsal was noted to be 18.9 ± 3.83 mm for males and 15.6 ± 4.02 mm for females. Our results indicate the shortened proximal phalanx is 5 mm shorter when compared to normal population and is a contributing factor to the shortened clinical appearance of the digit in brachymetatarsia. Treating surgeons should be aware of this to better educate patients on the influence of the digit on the overall shortening seen in cases of brachymetatarsia.

Development of a murine model of oral carcinogenesis: an accelerated tool for biomarker and anti-tumour drug discovery.

Oral squamous cell carcinoma (OSCC) is the most common cancer in Pakistani men and the second most common cancer in women. The objective of our study was to devise a novel accelerated murine model of oral carcinogenesis that can be exploited as a tool to investigate the cancer circuitry involved in OSCC and to identify molecules of diagnostic, therapeutic and prognostic significance. A total of 40 healthy male, 6-8 weeks old, 22 ± 2 gram, Naval Medical Research Institute (NMRI) outbred strain mice were recruited in the experiment. NMRI mice are commonly used for animal experiments in various fields of biology and for drug toxicity. Of these, 25 mice underwent the oral carcinogenesis regimen via topical application of 0.5% 9,10-dimethyl-1,2-benzanthracene (DMBA) on the lower left lip for a maximum of 20 weeks and 15 mice were used as controls (without the carcinogenic regimen). Exophytic tissue masses were harvested, fixed in 10% formalin and stained with haematoxylin and eosin (H&E) for microscopic diagnosis. Additionally, the expression levels of CK 5/6, p53 and Ki-67 were investigated using immunohistochemistry. Of the 25 mice which underwent the carcinogenic regimen, 21 developed moderately differentiated squamous cell carcinoma and 1 showed dysplastic features with foci of invasion. Three mice were found dead with lesion(s). CK 5/6 showed strong positivity (100%) and p53 and Ki-67 showed patchy (<30%) strong positivity in OSCC, suggesting the similarity of our model to human OSCC. We present an accelerated, close-to-human carcinogenesis, model of oral carcinogenesis using DMBA in NMRI mice that can be exploited to study the pathogenesis of oral squamous cell carcinoma and subsequently devise immunotherapy or targeted therapy.

Heparin purification by expanded bed anion exchange in a countercurrent chromatography column.

In this study, an expanded bed anion exchange in a countercurrent chromatography column (EB-CCC) technique for separation and purification of heparin, an anticoagulant and antithrombotic glycosaminoglycan, is reported for the first time. A comparative evaluation of the EB-CCC technique with the conventional fixed bed column chromatography (FBCC) revealed its effectiveness in improving adsorption at high flow rates and reducing separation time. A significantly higher maximum adsorption (91.66%) was exhibited by EB-CCC in comparison with FBCC (45.16%) at the eluent flow rate of 1 mL·min-1. Similarly, the experimental adsorption capacity of heparin was enhanced by 1.69, 2.06 and 2.58 times in the case of EB-CCC at the flow rates of 1, 2 and 5 mL·min-1, respectively. Moreover, the directly proportional amplification of double loaded resin and double column volume was demonstrated at an EB-CCC rotational speed of 300 rpm and a flow rate of 2 mL·min-1, and the experimental adsorption capacity was observed to increase from 66.42 to 136.48 mg·g-1 after amplification. Heparin purified by EB-CCC displayed higher potency (216.09 ± 11.89 IU·mg-1) as compared to FBCC (205.51 ± 7.90 IU·mg-1) and the initial crude heparin 134.17 ± 4.12 IU·mg-1. Furthermore, comparing to the purified heparin by FBCC, heparin purified by EB-CCC had low molecular weight, high FXa/FIIa, superior anticoagulation effect and enhanced suitability as an exogenous anticoagulant.

Knowledge and perception regarding prostate cancer among men in Karachi, Pakistan.

OBJECTIVE: To assess the perception and attitude towards prostate cancer and its screening practices in Pakistan. METHODS: The cross-sectional study was conducted at Ruth Pfau Civil Hospital, Karachi June to October 2019, and comprised male subjects aged >40 years with no prior diagnosis of prostate cancer who were enrolled from the community. Data was collected using a structured questionnaire which was available in English and Urdu languages. Data was analysed using SPSS 23. RESULTS: Of the 383 subjects, 144(37.6%) were aged 40-49 years, 302(78.9%) were married, 120(31.3%) had received education up to the secondary level, and 204(53.3%) earned. CONCLUSIONS: The level of knowledge regarding prostate cancer and its screening practices was poor, and the attitude towards its screening was negative.

The Development and Evaluation of a Patient Educational Resource for Cancer-Related Cognitive Dysfunction.

Cancer patients and survivors frequently experience cognitive deficits, including problems with attention and memory. These symptoms, referred to as cancer-related cognitive dysfunction (CRCD), are associated with distress. Learning about CRCD and self-management strategies may improve functioning and quality of life in cancer survivors. This study describes the development and evaluation of a CRCD resource for cancer patients. An educational booklet was developed in accordance with multiple evidence-based guidelines for cancer patient education. Cancer patients on chemotherapy (N = 113; 34% men; median age 55, range 19-85) reviewed the booklet and self-reported CRCD knowledge before and after reading the booklet. They also gave ratings on general impressions of the booklet. Seventy-five percent of participants reported that the resource increased their self-reported CRCD knowledge. A Wilcoxon signed-rank test demonstrated that exposure to the booklet elicited a statistically significant change in self-reported knowledge (Z = - 7.13, p < 0.001). A repeated-measures ANCOVA determined that the means of self-reported CRCD knowledge were significantly different between pre- and post-exposure (F(1, 92) = 7.96, p = 0.006, η2 = 0.08). Exploratory analyses revealed that self-reported CRCD knowledge increased across all educational attainment levels from pre- to post-exposure. Ninety-one percent of participants reported that all patients undergoing cancer treatment would find this booklet helpful. Cancer patients at risk for cognitive challenges gained self-reported CRCD knowledge from the booklet, and they think this knowledge would be helpful to others. A resource that makes CRCD understandable and manageable can bridge the gap in self-rated knowledge across education levels.

Unusual Local Therapies Used for the Treatment of Low Back Pain and Sciatica: Concepts and Approaches.

Background and objective Low back pain (LBP) and sciatica are major healthcare issues globally. Since patients may seek various ways to cure their ailments, these conditions are managed not just by physicians, but many other health-related professionals provide alternative treatment options for it as well. We conducted this study to examine a local subset of patients who used stabbing their back and legs as a treatment option for curing LBP and sciatica. Materials and methods This cross-sectional study was conducted in the outpatient clinic of the Neurosurgery unit of Government Naseer Ullah Babar Memorial Hospital, Peshawar, Pakistan, from July 2019 to March 2020. Patients who presented to the outpatient department (OPD) with complaints of LBP with or without sciatica, with a history of invasive therapy in the form of stabbing the back or leg, or drawing blood from the veins of the lower limbs, were included. All other patients with LBP seeking neurosurgical advice were excluded from the study. The study was approved by the management of the hospital and informed consent was obtained from the patients before interviewing them. Special permission was taken for publishing the photographs. The demographics and clinical information related to patients, such as age, gender, duration of symptoms, time since the local therapy, particulars of the treatment provider, any relief experienced by the patient, duration of relief, the patient beliefs/notions about the therapy and disease, and education level of the patients, were recorded on a predesigned form after taking informed consent. The study was done on purposive sampling. The data was presented in tables and charts and was analyzed using SPSS Statistics version 20 (IBM, Armonk, NY). Results During the study period, more than 8,000 patients visited the neurosurgical OPD, and the majority of them (>70%) sought treatment for LBP and sciatica. Of them, around 130 patients had a history of undergoing some alternative therapy that is not scientifically proven, and it was either in the form of stabbing the back or drawing blood from the veins in the lower limbs. Amongst these patients, almost 80% were males and 20% were females who had undergone this kind of treatment. The age range among the cohort was 25-68 years and the mean age was around 43 years. The duration of symptoms ranged from two months to nine years, and the time since the therapy and patient seeking medical advice ranged from three months to 4.5 years. The treatment had been provided by a local individual who did not hold any medical degree according to the patients in 100% (n=130) of the cases; 67% of patients felt they had experienced some relief from the therapy for a short period, which ranged from three days to one month. About the condition, none of the patients seeking the therapy knew it was nerve-related and were often confused about the term rugg (vessel in the native language) but could not differentiate it from the nerve. Of these patients, 76 required surgery while 54 were managed conservatively for LBP and sciatica. Conclusion A subset of the local population in our part of the world used stabbing the back and leg as a form of therapy for treating the problems of the lower back and sciatica. This has not been previously reported and has no scientific basis. Also, the majority of the patients were uneducated and had very little knowledge of the disease, and the treatment provider was a non-health-related professional.
