Introduction The present study aimed to examine the role of experience of psycho-trauma and perceived social support in the coping strategies of young adults. Moreover, it aimed to determine the role of demographic variables such as gender, age, education of respondents, paternal and maternal education, occupation, income, and nature of trauma experienced across the study variables. Methods The study utilized a quantitative cross-sectional survey design to examine the role of psycho-trauma, perceived social support, and coping strategies among 352 young adults aged between 18 and 28 years from Pakistan and Afghanistan (Islamabad and Jalalabad, respectively). Participants were selected through convenience sampling from various public and private universities. Data were collected using standardized instruments, including the Brief Trauma Questionnaire (BTQ), the Multidimensional Scale of Perceived Social Support (MSPSS), and the Brief Coping Orientation to Problems Experienced (COPE) Inventory. Results Results showed significant findings regarding the relationships between psycho-trauma, perceived social support, and coping strategies among a sample of 352 young adults. Inferential statistics revealed substantial negative correlations between psycho-trauma and both perceived social support (r = -0.18, p < 0.01) and problem-focused coping (r = -0.21, p < 0.01). Regression analysis indicated that psycho-trauma explained 19% of the variance in coping strategies, while perceived social support accounted for 29%. Gender differences were observed, with men scoring higher on problem-focused coping (t = 4.66, p < 0.02) and women scoring higher on emotion-focused coping (t = 3.12, p < 0.00). Conclusion The study also highlighted significant differences based on trauma experiences, education levels, and parental education and occupation, underscoring the complex interplay between these factors and their impact on young adults coping mechanisms. Study implications, limitations, and suggestions for future research have also been discussed., Competing Interests: Human subjects: Consent for treatment and open access publication was obtained or waived by all participants in this study.

Hepatocellular carcinoma (HCC) is the most common primary liver malignant neoplasm. Multiple risk factors have been identified for several decades for this overly aggressive tumor. HCC is an overly aggressive malignancy with frequent intrahepatic and extrahepatic metastasis. In our practice, we have observed that HCC has the propensity to metastasize to very unusual sites and can sometimes show variable patterns leading to diagnostic difficulty. In this study of 257 patients, we aim to discuss the unusual sites of HCC metastasis, the various patterns of metastasis, clinicopathological features, and the most common cause of HCC in our population. In the course of our research study, we systematically extracted a comprehensive dataset comprising 257 instances of metastatic HCCs from the hospital database spanning the period from 2016 to February 2022. The assessment of metastatic sites uncovered a wide range of locations, reflecting significant diversity. The most common location was bone, with 135 cases (52.5%). The vertebral column was the most common location among bony metastasis, with 63 cases (24.7%). Morphologically, the most common histological pattern observed was pure trabecular in 192 patients (74.7%). All cases were diagnosed with the help of immunohistochemical stains. Out of 257 cases, 29.18% were diagnosed using glypican-3 and HepPar1, while 26.1% relied solely on HepPar1 positivity. HepPar1 was performed in a total of 240 cases, and positivity was seen in 205 cases (85.5%). In summary, our study represents the most comprehensive investigation of clinicopathological characteristics in metastatic HCC conducted within the past 20 years. It helps understand the histological and immunohistochemical features useful for diagnosis at metastatic sites for tumors with an unknown primary., Competing Interests: Human subjects: Consent was obtained or waived by all participants in this study.

Background and objective Coronavirus disease 2019 (COVID-19), primarily a respiratory illness, also significantly impacts neurocognitive and emotional health, particularly in its long-term manifestation known as long COVID. This study aimed to investigate the neurocognitive and emotional outcomes of long-term COVID-19 in Pakistani patients, to address the persisting symptoms and their effects on mental health and cognitive function. Methods A cross-sectional study involving 100 adult participants who had been COVID-19-free was conducted in Islamabad between March 2022 and March 2023. Participants were assessed using the Mini-Mental State Examination (MMSE), attention-deficit/hyperactivity disorder (ADHD) Self-Report Questionnaire, Satisfaction with Life Scale (SWLS), and Punishing Allah Reappraisal Scale. Data were analyzed using SPSS Statistics v26 (IBM Corp., Armonk, NY), employing chi-square tests, t-tests, and ANOVA. Results The study revealed significant correlations between COVID-19 symptoms and psychological variables. COVID-19 symptoms showed a negative correlation with MMSE scores (r = -0.04, p<0.01) and positive correlations with ADHD (r = 0.13, p<0.05), depression (r = 0.14, p<0.05), and anxiety (r = 0.25, p<0.05). Females reported higher levels of depression [mean: 1.21, standard deviation (SD): 0.83] and anxiety (mean: 1.33, SD: 0.86) compared to males. Conclusions Our findings highlight the extensive impact of long-term COVID-19 on neurocognitive and emotional health, with significant gender differences observed in emotional outcomes. These results emphasize the need for integrated mental health services in post-COVID-19 care plans, as well as gender-sensitive interventions., Competing Interests: Human subjects: Consent was obtained or waived by all participants in this study.

Introduction: The gut-brain axis is a bidirectional communication network linking the gastrointestinal tract and the central nervous system via neuronal, hormonal, and antibody signaling pathways. Central to this connection is gut health, encompassing the balance and functionality of gut microbiota, which significantly impacts on mental and cognitive health. This study investigates the association between gut health and cognitive functioning in adults, highlighting the mechanisms by which gut microbiota influence brain health., Objective: To examine the effects of gut health on adult cognitive performance, with a focus on the processes by which gut microbiota impacts brain health., Methods: A quantitative cross-sectional study was conducted in Islamabad from January 2024 to April 2024, involving 140 adult participants. Data were collected using a comprehensive 16-item gut health questionnaire and the cognition self-assessment rating scale (C-SARS). The psychometric properties of these scales were assessed, and the data were analyzed using Statistical Product and Service Solutions (SPSS, v26; IBM SPSS Statistics for Windows, Armonk, NY). Analytical and descriptive statistics, including regression, chi-square, independent sample t-tests, and mean and standard deviation, were applied., Results: The study found moderate associations between gut health and cognitive performance, particularly in memory and processing speed (R² = 0.17, β = -1.9, p = 0.12 for general cognition; R² = 0.01, β = -0.98, p = 0.02 for memory; R² = 0.03, β = -0.18, p = 0.03 for processing speed). Gender and marital status differences were significant, with males exhibiting better gut health scores than females (M = 34.1, SD = 3.2 vs. M = 31.2, SD = 3.2, p = 0.00), and singles showing better cognitive performance compared to married individuals (M = 9.4, SD = 5.4 vs. M = 6.5, SD = 3.7, p = 0.03)., Conclusion: The study highlights significant associations between gut health and cognitive functions, suggesting that gut microbiota composition can influence cognitive performance. Gender and marital status differences underscore the need to consider individual differences in gut-brain axis research. Future studies should replicate these findings in larger samples and explore gut microbiota-targeted interventions for cognitive health enhancement., Competing Interests: Human subjects: Consent was obtained or waived by all participants in this study.

Background and Objectives: The Achilles tendon, the largest and strongest tendon in the human body, is frequently injured by overuse; this condition is known as Achilles tendinopathy (AT). It serves as a link between the heel bone and the calf muscles and is necessary for motions, such as walking, sprinting, and jumping. Evidence is presented to support the efficacy of the Graston technique and Alfredson protocol for pain reduction and improvement of function and calf muscle strength. The objective of this study is to compare the efficacy of the Graston technique versus the Alfredson protocol in patients with AT. Methods and data collection: After obtaining approval from the ethical review board of the Rawalpindi Medical University, all patients fulfilling the inclusion criteria are divided into two groups, A and B, by generating random identity numbers using Microsoft Excel for allocation. Group A comprises patients who undergo treatment with the Graston technique as conventional therapy with Alfredson protocol (12-week calf muscle eccentric exercises), while those in group B follow a Graston technique with sole heel lift. Individuals in the eccentric exercises group follow an Alfredson method-based 12-week eccentric exercise plan for their leg muscles. The workouts need to be done twice a day, seven days a week for 12 weeks. The plan includes two exercises: the first done with the knee straightened to work the gastrocnemius and the second done with the knee bent to work the soleus. Three sets of 15 repetitions with no rest interval for each exercise are completed twice a day on the affected limb to yield functional improvement., Results: The results showed that both the Alfredson protocol and the Graston technique were effective in managing AT symptoms. The study involved dividing 32 participants into two groups who received either treatment for four weeks. The main way to measure improvement was a score called the Villalta-Scanlon Achilles Tendonitis Index score. In both groups, these scores showed significant improvement (with a p-value less than 0.001, which means that the results are very statistically significant). For Group A (who received the Alfredson protocol), the average Villalta-Scanlon Achilles Tendonitis Index score before treatment was 29.25. This score increased to 31.25 at mid-treatment and 34.38 after the full four weeks of treatment. Group B (who received the Graston technique) started with an average Villalta-Scanlon Achilles Tendonitis Index score of 22.94. Their scores also increased throughout the treatment, reaching 34.94 at mid-treatment and 42.88 after four weeks. These findings provide evidence that both treatments can improve AT symptoms, with some suggestions that the Graston technique might be even more effective based on the higher average Villalta-Scanlon Achilles Tendonitis Index scores after treatment., Conclusions: The Graston technique shows promising results, particularly in the mid- and post-treatment phases, indicating its potential efficacy in comparison to the Alfredson protocol in the treatment of AT., Competing Interests: Human subjects: Consent was obtained or waived by all participants in this study.

Introduction: The present study investigated the predictive relationship between ostracism and suicidal behaviors in individuals with substance use disorders. It also attempts to highlight the mediating role of the risk of relapse between ostracism and suicidal behavior., Methods: The study was based on a cross-sectional survey design. The sample comprised 100 men aged between 30 to 45 years (M = 35.25, SD = 3.06) from Karachi. The purposive sampling technique was employed. The study employed demographic forms and three self-reporting measures: the Ostracism Experience Scale (OES-A), the Advance Warning of Relapse Questionnaire 3.0 (AWARE), and the Suicide Behaviors Questionnaire-Revised (SBQ-R)., Results: Ostracism significantly predicted relapse risk and suicidal behavior. Risk of relapse positively predicted both dimensions of ostracism (ignored: r = 0.33, p < 0.01; excluded: r = 0.43, p < 0.01) and suicidal behavior (r = 0.35, p < 0.01). Additionally, the risk of relapse strongly correlated with overall ostracism score (r = 0.43, p < 0.01). However, no significant mediating effect of ostracism on suicidal behavior was found. The effect was mediated through the risk of relapse (B indirect = 0.12, 95% CI = 0.04, 0.23). These findings suggest that ostracism increases the likelihood of recurrence, which in turn is associated with suicidal behavior. The mediation model explained 17% of the variation in suicidal behavior., Conclusion: The findings propose the importance of addressing ostracism as a risk factor for suicidal behavior and relapse in substance use disorders. The results suggest that reducing the adverse effects of ostracism and improving social support for individuals can have a significant impact on their mental health., Competing Interests: Human subjects: Consent was obtained or waived by all participants in this study.

Background Low-grade fibromyxoid sarcoma (LGFMS) and sclerosing epithelioid fibrosarcoma (SEF) are two rare but aggressive soft tissue sarcomas that can be difficult to distinguish due to histopathological similarities. The present study examines the diagnostic capacities of mucin-4 (MUC4), a transmembrane mucin, in identifying different types of sarcomas and broadens its evaluation to include a wide range of sarcomas. Methods Immunohistochemical (IHC) examination of tissue samples from various sarcomas was performed using a mouse anti-MUC4 monoclonal antibody. IHC was conducted on 4-mm thick formalin-fixed paraffin-embedded tissue sections after pressure cooker antigen retrieval with a mouse anti-MUC4 monoclonal antibody. Results MUC4 was shown to be highly expressed in SEF (n=13) and LGFMS (n=10), while focal positivity in synovial sarcoma (n=1). Other sarcomas, such as malignant peripheral nerve sheath tumors, fibrosarcoma, leiomyosarcoma, liposarcoma, and myxofibrosarcoma, exhibited no expression (n=0). These findings are consistent with previous research and support MUC4 specificity as a SEF and LGFMS marker. This study provides information on the diagnostic efficacy of MUC4, particularly in the context of certain subtypes. It not only helps our understanding of these unique instances, but it also provides context for histopathological and IHC findings in soft tissue sarcoma. Furthermore, this study investigates the influence of age and gender on MUC4 expression in a range of sarcomas, which was typically understudied in the literature and found no relation with expression of MUC4. Conclusion In conclusion, this study adds to our understanding of soft tissue sarcomas by emphasizing the crucial role of MUC4 in certain sarcoma subtypes while acknowledging the complex variety of the sarcoma landscape. Further research is needed to understand the molecular mechanism that governs marker expression patterns, as well as the therapeutic implications., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2023, Hassan et al.)

Fungal rhinosinusitis (FRS) is a relatively common, but often misdiagnosed disease of paranasal sinuses. The FRS is classified into invasive and non-invasive forms. The non-invasive form includes fungal ball and allergic FRS, and invasive form includes acute invasive FRS, chronic invasive FRS, and granulomatous FRS. Invasive fungal infections are associated with high morbidity and mortality, hence requiring urgent medical and surgical intervention. The histomorphology can help identify certain fungal organisms that cannot be cultured or are rarely visible in exudates. The morphologic diagnosis of tissue invasive and non-invasive fungal infection is essential for appropriate treatment. We analyzed cases of rhinosinusitis from 2017 to 2019 in Pathology Department at a tertiary care cancer hospital, Lahore, Pakistan. All clinical information was retrieved from patient records. Paraffin-embedded tissue blocks were stained with hematoxylin and eosin (H&E), special Grocott methenamine silver stain (GMS), and periodic acid Schiff stain (PAS) according to standard protocol. They were reviewed by two pathologists blinded by fungus status. A total of 169 cases of rhinosinusitis were reviewed. FRS comprised 146 (86.4%) of them. The mean age of patients with FRS was 32.8±14 years. The male:female ratio was 1.4:1. Maxillary sinus was the main site of involvement in 39 (27%) FRS cases. Aspergillus was identified in 117 (80.1%) cases of FRS. The culture reports were available in 44/146 (30.14%) FRS cases. They were negative in 22/44 (50.0%), and Aspergillus species were isolated in 18/44 (40.9%) cases of FRS. There were 84 (57.5%) cases of non-invasive FRS and 59 (40.4%) cases of invasive FRS. Among invasive FRS, there were 56 (38.4%) chronic granulomatous FRS cases including mixed patterns. Majority cases, 54 (96.4%), of chronic granulomatous FRS showed a unique crowded giant cell pattern comprising of foreign body and Langhans type giant cells. These giant cells were arranged closely forming irregular non-caseating granulomas surrounded by lymphocytes and fibrosis. Interestingly, the giant cells were scattered haphazardly without forming a granuloma as well. Fungal organisms were identified in all 56 cases of chronic granulomatous FRS. Histologically, predominant organism was Aspergillus in 48 (85.7%) on GMS and PAS stain. Our study observed a unique crowded giant cell pattern, which is a hallmark of invasive fungal infection. If pathologists are familiar with this unique pattern, they can make a quick and accurate diagnosis on histology. The physician can start antifungal treatment timely for better prognosis., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2023, Maruf et al.)

The use of statins may be associated with muscle-related side effects ranging from myalgia to rhabdomyolysis. A rare adverse effect is statin-induced anti-hydroxy-3-methyl-glutaryl-coenzyme A reductase (anti-HMGCR) necrotizing myositis, which may develop after exposure to statins due to autoantibodies against HMG-Co-A reductase. We present the case of a 76-year-old male who developed progressive muscle weakness three years after exposure to statins. He had significantly elevated creatine kinase (CK) levels, despite the discontinuation of statins three years prior. He complained of generalized muscle weakness, and examination revealed reduced strength, especially in the proximal musculature. MRI revealed inflammatory myositis of the medial and posterior compartments of bilateral thighs. Autoimmune workup was positive for anti-HMG-CoA reductase antibodies. Muscle biopsy showed endomysial inflammation with fibrosis and fat replacement, suggesting chronic but active myositis. A diagnosis of chronic anti-HMGCR necrotizing myositis was made. The patient was started on oral prednisone and methotrexate with improvement in symptoms and CK levels. This case highlights a chronic form of a rare cause of myositis that may be a challenge to diagnose given the remote exposure to statins., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2023, Salar et al.)

Focal segmental glomerulosclerosis (FSGS) is a common renal disorder, characterized by progressive segmental sclerosis of renal glomeruli and clinical symptoms corresponding to proteinuria. Classically, it is not considered to be an antibody-mediated disease, however, IgM and C3 deposition may be seen in a subset of cases of FSGS. The impact of this immune deposition on histopathological features in renal core biopsies, on the urinary biochemical parameters, and the clinical outcomes, has not been previously investigated in our population. The aim of this study is to analyze the aforementioned parameters in patients with primary FSGS having antibody deposition as compared to those who do not have any antibody deposition. Some 155 patients diagnosed with FSGS were retrospectively enrolled in our study. The renal biopsies were reviewed for histopathological features and immunofluorescence (IF) findings of IgM and C3 glomerular deposition. These histological features were then compared with the biochemical parameters as well as the clinical outcomes of patients. The patients were assigned to Groups 1 and 2 based on the IF findings. The IgM and/or C3 glomerular deposition had a low incidence in patients with primary FSGS in our study (28.3%). Patients having IgM and C3 co-deposition had a significantly longer time duration since the onset of their clinical symptoms; active disease duration (42 months vs 22 months, p=0.049). The mean pre-treatment serum creatinine of patients with IgM and C3 co-deposition was 6.00 mg/dL as compared to 3.29 mg/dL in patients with no immune deposition (p=0.037). The immune deposition was associated with higher rates of segmental and global glomerulosclerosis, but this finding along with other evaluated histological parameters did not show statistical significance. The number of patients having IgM and/or C3 deposition and with active steroid use/renal dialysis was similar to patients having no IgM and/or C3 deposition. The IgM and/or C3 deposition in FSGS has a low incidence within and is not associated with any significant differences in histological parameters on renal core biopsies of patients from the Pakistani population. IgM and/or C3 deposition is also associated with a significantly longer duration of active disease and these patients may present with higher pre-treatment serum creatinine. Other biochemical parameters and clinical outcomes appear comparable between the groups based on the available clinical data., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2023, Amer et al.)

Background Malignant melanoma is a common cancer in Scandanavian countries due to increased exposure to ultraviolet light. Very limited data is available on malignant melanomas in Pakistani population and further studies are needed to determine its incidence in our population. Objective The main objective of our study was to determine histopathological characteristics and prognosis of malignant foot melanomas in Pakistani patients. Material and methods After approval by the Institutional Review Board, we performed a retrospective study of 59 consecutive cases of malignant acral melanoma from the year 2016-2019. The follow-up of in-house cases was available in hospital archives. The follow-up of diagnostic patients was done through direct communication. The histological features were assessed, and the prognosis was determined in terms of recurrence, metastasis, and death. Results The main histological features assessed were Breslow thickness <1 (n=3), >1-2 (n=9), >2-4 (n=12), >4 (n=36), ulceration was present in 65% (n=39), and pathological stage 1 (n=3), stage 2 (n=9), stage 3 (n=12) and stage 4 (n=36). The margin was involved in 28.3% (n=17) cases. Recurrence was observed in 47.4% (n=28), metastasis in 55.9 % (n=33), and death was observed in 49.1% (n=29). The mean follow-up duration of 3.4 years ± 0.20 (Range 3 to 6 years). The recurrence-free survival was 2.9 ± 0.24 years, metastasis-free survival was 2.8 ± 0.237 years, and disease-specific survival was 3.4 ± 0.203 years.  Conclusion Malignant acral melanoma is fatal with high mortality rates. In our part of the world, acral melanoma has poor prognosis compared to non-acral melanomas. When compared with acral melanomas in other parts of the world prognosis is even worst. Early diagnosis and treatment are crucial in terms of patient management., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2023, Shahid et al.)

Background Autoimmune disorders have shown an increasing incidence in the last few years. The systemic response to the disorder is characterized by the expression of antinuclear antibody (ANA), which serves as the serological hallmark of autoimmunity. Its presence may indicate either a systemic autoimmune disease such as systemic lupus erythematosus (SLE), scleroderma, and polymyositis/dermatomyositis or an organ-specific condition such as autoimmune thyroiditis and hepatitis. The systemic response may vary from one individual to another in each population. Several specific autoantibodies are also found to be associated with specific rheumatic diseases. Aim We aim to report the frequency of ANA positivity, ANA immunofluorescence patterns, and the presence of extractable nuclear antigen (ENA) among the general Pakistani population from one of the largest laboratories in Pakistan. Material and methods A total of 1,966 blood samples from a random Pakistani population were included, who were referred by their physicians with suspicion of autoimmune disease. These blood samples were subjected to ANA testing by indirect immunofluorescence method, and subsequently, positive samples were further analyzed for ENA detection in the Section of Chemical Pathology, Department of Pathology at Shaukat Khanum Memorial Cancer Hospital and Research Centre, Lahore, Pakistan. An ANA titer of ≥1:80 was taken as positive. ANA was divided into subgroups based on titer: negative, weakly positive (titer of 1:80 or 1:160), moderately positive (titer of 1:320 or 1:640), and strongly positive (titer of ≥1:1280). Further, the frequency of ANA in male and female participants was studied in different age groups (2 to <10, 10 to <20, 20 to <30, 30 to <40, 40 to <50, 50 to <60, 60 to <70, 70 to <80, and 80+ years). Results This study included 1,966 participants, out of which 1,100 (55%) were ANA-positive at a titer of ≥1:80. Out of these ANA positives, the proportion of weakly positive (titer of 1:80 or 1:160), moderately positive (titer of 1:320 or 1:640), and strongly positive (titer of ≥1:1280) were 48.7%, 2.6%, and 4.2%, respectively. The ages ranged from two to 91 years, with a mean age of 43.64 ± 17.4 years. Females (75.5%) showed predominance over males (24.5%) in all age groups, with a ratio of 3:1. The age group in which most ANA positivity was found was 30 to <40 years. Among 1,100 ANA-positive sera, 383 (34.8%) participants tested positive for at least one out of 15 ENA. The most frequent autoantibodies noticed were anti-recombinant Ro52 (Ro52) (19.8%), anti-Sjogren's syndrome type A (SSA) (17.2%), and anti-ribonucleoprotein (RNP) (13.3%). The most prevalent ANA patterns were nuclear homogeneous (27.7%), followed by nuclear speckled (26.5%). Conclusion The frequency of ANA positivity is high in the Pakistani population and differs in different sex and age groups., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2023, Imran et al.)

Objective: To determine the proportion of female authors publishing in Pakistan and their representation in academic anesthesiology . Design, place, and duration of study: This study was a cross-sectional retrospective analysis. We reviewed all volumes and issues of the Journal of the College of Physicians and Surgeons Pakistan (JCPSP) published from 2007 to 2021. All original articles, clinical practice articles (CPAs), reviews, and editorials were included. The first and last authors publishing in JCPSP were the study subjects., Main Outcome Measures: Gender of the first and last authors was determined by (a) a general review of the author's first, middle, and last names, (b) an internet search of the author's name, and a review of photographs on their social media, or (c) an online search of the author's first name for typical gender assignment. The research field of the first author was noted to determine the contribution of different medical specialties. Article type and the number of citations were noted to determine the relationship with the gender of the author., Results: Around 1549 papers were published by Pakistani authors, of which, 82.6% were original articles, 9.8% were editorials, 5.5% were CPAs, and 2.1% were reviews. Around 56.2% of the first authors and 70.9% of the last authors were males. Most article types had a majority of male first and last authors (<0.001). The median (interquartile range) citation rate was two (0-19), with no difference in citations between gender. Male-male author pairing remained the most common (45.6%). The majority of the papers published belonged to the field of medicine (27.2%) and surgery (21%), with only 3.1% contributed by anesthesiology (females: 41.3%; males: 58.6%)., Conclusion: Female representation in academia in Pakistan is at par with developed countries. The academic contribution from anesthesiology remains low, which corresponds to a lower percentage of the anesthesia workforce in the country. There is a need for a national indexed journal of anesthesia to evaluate the true representation of female authors in the country., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2022, Ismail et al.)

Vancomycin-induced immune thrombocytopenia (ITP) is a rare type of drug-induced immune thrombocytopenia (DITP) that can lead to life-threatening consequences as a result of its use. We herein report a case of a 74-year-old male with a history of diabetes mellitus type II, Alzheimer's disease, and stroke who presented to the ICU with sepsis. The patient was on heparin for 20 days prior to presentation, with platelet levels at the time within normal limits as per his baseline. Following the introduction of vancomycin to his clinical regimen in the treatment of sepsis, the patient developed a significant drop in platelet count from 400 x10³/mm³ to 70 x10³/mm³. Discontinuation of the drug leads to improvement of the platelet counts confirming the diagnosis of vancomycin-induced ITP., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2022, Hameed et al.)

The small cell carcinoma of ovaries co-occurring with mucinous ovarian cancer is a rare event. We report a 21-years-old lady with a composite tumour comprising small cell carcinoma and mucinous carcinoma of ovaries. The incidental finding of the left ovarian cyst led to further workup and revealed a solid cystic mass in the left adnexal area pathologically proven to be mucinous ovarian carcinoma. The initial surgery was deferred upon the patient's request. After a few more cycles of chemotherapy, at the completion of surgery as per ovarian protocol, the pathological evaluation showed small cell carcinoma in the left ovary with a residual focus of mucinous carcinoma. In contrast, the right ovary also showed surface deposits of small cell carcinoma. The patient's clinical condition deteriorated very rapidly after that, and she passed away. Early recognition of small cell carcinoma in a composite tumour is critically essential for timely intervention., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2021, Mannan et al.)

Introduction: Fibroadenomas (FAs) and phyllodes tumors (PTs) are less prevalent but allied to have malignant transformation in many instances. It is a challenge to diagnose the phyllodes by conventional trucut biopsy technique., Objective: To evaluate the histological characteristics of tumors labeled as fibroepithelial lesions of breast tissues on trucut biopsy and compare with a diagnosis on excision biopsy., Methods and Materials: It was a descriptive cross-sectional study that was carried out in Shaukat Khanum Memorial Hospital and Research Centre within six years from January 2015 to January 2021. In trucut samples, stromal cellularity, stromal cell nuclear atypia, mitotic count, stromal overgrowth, the enhancement of stromal cellularity adjacent to epithelium were scrutinized. In each category, the activity was seen as absent, mild, moderate, or severe. Mitotic activity was graded as 0-1, 0-5, 5-10, >10., Results: A total of 125 patients were registered for the study. The mean age of patients in our study was 33.86 ± 9.95 years. The mean size was 41.02 ± 27.38 mm with a mean lump duration of 7.52 ± 5.34 months. In the FA group, the trucut sampling report showed the stromal cellularity as mild in 62 (69.7%) and stromal cell nuclear atypia as absent in 68 (76.4%) cases. But in the phyllodes tumor group, the stromal cellularity was severe in 10 (27.8%) patients and stromal cell nuclear atypia was severe in five (13.9%). The ultimate outcome showed that 89 (71.2%) patients had FA and 36 (28.8%) had PT at excision., Conclusion: Assessment of tumor size, stromal cellularity, mitoses, and enhancement of stromal cellularity adjacent to epithelium are useful markers for diagnosing the PT in trucut needle biopsy., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2021, Latif et al.)

Thyrotoxic hypokalemic periodic paralysis (THPP) is a rare but life-threatening complication of hyperthyroidism seen predominantly in males. It is generally characterized by hypokalemia and skeletal muscle paralysis requiring intensive care admission. Hypokalemia occurs due to the massive intracellular shift of potassium because of the hyperactivity of the sodium-potassium adenosine triphosphates pump (Na +  K +  ATPase). Its differential diagnosis from the other common causes of hypokalemic paralysis is essential to provide targeted therapy. We present a rare case of THPP in a female patient with no prior history of thyroid disease. THPP in this patient was precipitated by trauma and emotional stress, which served as a diagnostic challenge. Both hypokalemia and elevated levels of T3 and T4 are important diagnostic features during the acute episode. Treatment of THPP includes nonselective beta-blockade, which prevents the shift of intracellular potassium, and potassium replacement. THPP is curable once a euthyroid state is achieved., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2021, Nazir et al.)

Coronavirus disease 2019 (COVID-19) is an infectious disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). It has spread globally, resulting in an ongoing pandemic. Real-time reverse transcription-polymerase chain reaction (rRT-PCR) from a viral swab is diagnostic. The most common site to take this swab is from the nasopharyngeal area; however, patients with tracheostomies represent a major challenge as they have two sources for colonization and possible infection including the nose and the trachea. We present the case of a patient who had a COVID-19 diagnostic swab through his tracheostomy, when unfortunately the swab broke, resulting in a bronchial foreign body., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2020, Hussein et al.)

The pineal gland is a small pinecone-shaped and functionally endocrine structure located in the epithalamus region. Developmentally, the pineal gland is considered as a part of the epithalamus. It plays a role in the entrainment of the circadian rhythms of an organism by producing melatonin, a functionally important hormone. Lesions of the pineal region are rare compared to other parts of the brain. A lesion may be tumorous or non-tumorous in nature. The most common lesions are tumors that are pineal parenchymal tumors (PPT) in origin. Gliomas are the second most common tumors in the pineal region. We report a case of a high-grade oligodendroglioma, not commonly seen in the pineal region, in a 45-year-old male. The patient was suspected to have a mass in the pineal region on a computed tomography (CT) scan and histology confirmed the diagnosis of oligodendroglioma. This is a unique case because only five such cases have been reported so far., Competing Interests: The authors have declared that no competing interests exist.
