Abstract
Teratomas are germ cell tumors occurring usually in gonadal organs. They are neoplasms composed of one or more of the three germ layers. Extragonadal teratomas are uncommonly reported in the literature. The liver is an extremely rare site for teratoma, constituting < 1% of all teratomas. The majority of the liver teratomas are found in the pediatric population with only a dozen cases reported in adults to the best of our knowledge. We present a case of a 27-year-old male with a history of abdominal pain of 5 months duration. CT scan revealed liver mass suggesting teratoma. The patient underwent cholecystectomy and segmental liver resection. Histopathology revealed mature cystic teratoma. Complete resection remains the best treatment option. Teratomas of the liver are extremely rare, constituting < 1% of all teratomas. An extensive review of the literature yielded < 50 cases of primary hepatic teratomas with only a dozen cases in adults and only two cases in males.

Abstract
Abstract
Objective
This study sought to describe the clinical profile, management and short-term outcomes of patients with ST elevation myocardial infraction (STEMI) due to totally occluded unprotected left main coronary artery (TOULM).
Methods
This is a retrospective analysis of nationwide STEMI database of patients who underwent primary percutaneous intervention (PPCI). Patients with TOULM are defined as having 100% acute thrombotic occlusion of the left main artery or subtotal occlusion with no more than TIMI 1 flow.
Results
Between January 2011 and February 2022, 7107 patients underwent Primary Percutaneous Intervention for STEMI. 35 cases (0.5%) of all STEMI were due to TOULM. The average age of patients with TOULM was 51±14 years, predominantly male (94%) and had no prior cardiac history (94%). 11 patients (31%) suffered cardiac arrest and 16 (45%) were on mechanical ventilation prior to arrival to cardiac catheterization laboratory.
The right coronary artery was the dominant vessel in 29 (89%) patients. Right to left collaterals were present in 15 (42%), absent in 8 (23%) and unknown (the right coronary artery was injected after TOULM intervention or not injected) in 12 (34%) patients. Mechanical circulatory support was used in 37% of the cases (IABP 8, ECMO 3 and ECMO plus IABP 2). Revascularization was achieved with PCI and stenting in 30 patients (86%). Five patients underwent urgent CABG after balloon angioplasty. Survival to hospital discharge was 55%.
Conclusions
STEMI due to TOULM is a rare occurrence and involved mainly male with no prior cardiac history. Despite all the patients in our series undergoing revascularization, the in-hospital mortality is almost 50%. One major limitations of our study is we had no post-mortem data of any patient who died prior to coronary angiography, which potentially will lead to higher recorded cases of TOULM related mortality.

Abstract
This study explored the roles of activins and follistatin in colorectal cancers. Paired malignant and normal colonic tissues were collected from archived paraffin-embedded (n = 90 patients) alongside fresh (n = 40 patients) specimen cohorts. Activin β-subunits, follistatin and Smad4 mRNAs and proteins were measured by real-time PCR and immunohistochemistry (IHC). Mature activin-A, -B, -AB and follistatin proteins were measured by ELISA. Cancer tissues having ≤ the 20th percentile of the Smad4 IHC score were considered as low (L-S4) group. The Smad4-intact SW480 and Smad4-null HT29 colon cancer cell lines were treated with activins and follistatin, and cell cycle was analysed by flow cytometry. The cell cycle inducing (CCND1/CCND3) and inhibitory (p21/p27) proteins alongside the survival (survivin/BCL2) and pro-apoptosis (Casp-8/Casp-3) markers were measured by immunofluorescence. Thirty-nine patients had right-sided cancers (30%) and showed higher rates of L-S4 tumours (n = 17; 13.1%) alongside worse clinicopathological characteristics relative to left-sided cancers. The βA-subunit and activin-A increased, whilst βB-subunit and activin-AB decreased, in malignant sites and the late-stage cancers revealed the greatest abnormalities. Interestingly, follistatin declined markedly in early-stage malignant tissues, whilst increased significantly in the advanced stages. All activin molecules were comparable between the early stage right- and left-sided tumours, whereas the late-stage right-sided cancers and L-S4 tumours showed more profound deregulations. In vitro, activin-A increased the numbers of the SW480 cells in sub-G1 and G0/G1-phases, whereas reduced the HT29 cell numbers in the sub-G1 phase with simultaneous increases in the G0/G1 and S phases. The p21/p27/Casp-8/Casp-3 proteins escalated, whilst CCND1/CCND3/BCL2/survivin declined in the SW480 cells following activin-A, whereas activin-A only promoted p21 and p27 alongside reduced CCND3 in the HT29 cells. By contrast, activin-AB increased the numbers of SW480 and HT29 cells in Sub-G1 and G0/G1-phases and promoted the anti-cancer and reduced the oncogenic proteins in both cell lines. In conclusion, activins and follistatin displayed stage-dependent dysregulations and were markedly altered during the advanced stages of right-sided and L-S4 cancers. Moreover, the activin-A actions in CRC could be Smad4-dependent, whereas activin-AB may act as a Smad4-independent tumour suppressor protein.

Abstract
INTRODUCTION Lower limb amputees, regardless of age are at an increased risk of developing fragility fractures of the neck of femur. The characteristics and outcomes of the fractures of the neck of femur in lower limb amputees have not been studied in detail. METHODS We undertook a retrospective review of a prospectively collected single centre and single surgeon database between March 1996 and January 2017, using a standard proforma to identify patients who required surgical intervention for fracture neck of femur and had sustained a previous lower limb amputation and compared them with a cohort of standard hip fracture patients. RESULTS Twenty-seven patients, sustaining 28 fractures of the neck of femurs were identified of which 16 were females with mean age of 78 years (50-89). Nineteen fractures were sustained on the ipsilateral side of the amputation. Results showed that seventy percent of amputees returned to their previous level of mobility and prior residence. Mortality in this group is higher as compared to a standard hip fracture patient but pain and mobility were comparable in both groups. DISCUSSION The incidence of both hip fractures and amputations in increasing worldwide but no study has compared outcomes of hip fractures in amputees and compared them to a standard hip fracture patient. Amputees exhibit reduced bone density both at the hip and stump end which increases risk for osteoporosis and fragility fractures in the hip. The management of our patients followed orthopaedic principles, well established surgical interventions and rehabilitation. CONCLUSION This study reveals that hip fractures in amputees can have comparable results to a standard hip fracture cohort if preoperative optimisation, planning and postoperative rehabilitation is carried out.

Abstract
Differentiating epileptic seizures (ES) and psychogenic nonepileptic seizures (PNES) is commonly based on electroencephalogram and concurrent video recordings (vEEG). Here, we demonstrate that these two types of seizures can be discriminated based on signals related to autonomic nervous system activity recorded via wearable sensors. We used Empatica E4 Wristband sensors worn on both arms in vEEG confirmed seizures, and machine learning methods to train classifiers, specifically, extreme gradient boosting (XGBoost). Classification performance achieved a predictive accuracy of 78 ± 1.5% on previously unseen data for whether a seizure was epileptic or psychogenic, which is 6 standard deviations above the baseline of 68% accuracy. Our dataset contained altogether 35 seizures from 18 patients out of which 8 patients had 13 convulsive seizures. Prediction of seizure type was based on simple features derived from the segments of autonomic activity measurements (electrodermal activity, body temperature, blood volume pulse, and heart rate) and forearm acceleration. Features related to heart rate and electrodermal activity were ranked as the top predictors in XGBoost classifiers. We found that patients with PNES had a higher ictal heart rate and electrodermal activity than patients with ES. In contrast to existing published studies of mainly convulsive seizures, our classifier focuses on autonomic signals to differentiate convulsive or nonconvulsive semiology ES from PNES. Our results show that autonomic activity recorded via wearable sensors provides promising signals for detection and discrimination of psychogenic and epileptic seizures, but more work is necessary to improve the predictive power of the model.

Abstract
Small cell carcinoma of the ovary, hypercalcemic type (SCCOHT) is a very rare and lethal tumor, mostly affecting young women, with aggressive clinical course. It has a worse prognosis in younger women and most of them died within two years of diagnosis. We are reporting a unique case of SCCOHT in a 35 years old, nulliparous lady with primary infertility in which symptomatic hypercalcemia was a presenting feature of her cancer. She was completely healthy before third cycle of IVF. Within two months of her third IVF cycle, she developed SCCOHT with a very rapid and aggressive course of disease and fatal outcome. Patient died within one month of her first symptom presentation (3 months after IVF cycle).

Abstract
Leptomeningeal carcinomatosis (LMC) is a diffuse or multifocal malignant infiltration of the pia matter and arachnoid membrane. The most commonly reported cancers associated with LMC are breast, lung, and hematological malignancies. Patients with LMC commonly present with multifocal neurological symptoms. We report a case of LMC secondary to gastroesopha-geal junction cancer present initially with cauda equina syndrome. A 51-year-old male patient with treated adenocarcinoma of the gastroesophageal junction presented with left leg pain, mild weakness, and saddle area numbness. Initial radiological examinations were unremarkable. Subsequently, he had worsening of his leg weakness, fecal incontinence, and urine retention. Two days later, he developed rapidly progressive cranial neuropathies including facial diplegia, sensorineural hearing loss, dysarthria, and dysphagia. MRI with and without contrast showed diffuse enhancement of leptomeninges surrounding the brain, spinal cord, and cauda equina extending to the nerve roots. Cerebrospinal fluid cytology was positive for malignant cells. The patient died within 10 days from the second presentation. In cancer patients with cauda equina syndrome and absence of structural lesion on imaging, LMC should be considered. To our knowledge, this is the first case of LMC secondary to gastroesophageal cancer presenting with cauda equina syndrome.

Abstract
Objective. This was a comparative study between FNAC and thyroid scan used to diagnose the solitary thyroid nodule and histopathology was used as gold standard to compare the results of both modalities. We hypothesized that Fine needle aspiration cytology and thyroid scan diagnose solitary thyroid nodule (STN) as accurately as histopathology. Materials and Methods. This study comprised of 50 patients with solitary thyroid nodules (STN) presented to OPD. After clinical examination these patients were referred to Centre for Nuclear Medicine, Mayo Hospital Lahore for thyroid function tests and thyroid scan (TS). These patients underwent FNAC in the department of Pathology and surgery in Mayo Hospital. The cases were operated and evaluated for histopathological changes. Results. On thyroid scan, 40 patients (80%) having cold nodule were labeled as suspicious 10 patients (20%) had hot nodule. On FNAC 23 patients (46%) had benign lesion, 22 patients (44%) had indeterminate lesion and 5 patients (10%) had malignant lesions. On histopathology, 45 patients (90%) were confirmed to have benign lesions and 5 patients (10%), malignant lesions. After comparison of results of thyroid scan and FNAC with histopathology, the sensitivity, specificity, positive predictive value, negative predictive value and diagnostic accuracy of thyroid scan were 80%, 20%, 10%, 90% and 26%, respectively whereas those of FNAC were 80%, 97.7%, 80%, 97.7% and 96%, respectively. Conclusion. Fine needle aspiration was a significantly better predictor of malignancy than thyroid scan and resulted in a smaller proportion of excisions for benign nodules.

Abstract
Pituitary tumor transforming gene (pttg) is a recently isolated oncogene that is expressed in most of the tumors. Overexpression of pttg results in an increase in cell proliferation, induces cell transformation in vitro, and promotes tumor formation in nude mice. The gene encodes a protein of 202 amino acids with no significant homology with other known proteins. The protein is a multi domain consisting of a transactivation domain, domain required for ubiquitin-mediated proteolysis and a DNA binding domain. pttg protein is bestowed with a multitude of functions and seems to be involved in most of the important mechanisms of cell proliferation, differentiation and signaling. Given the number of processes that are involved in the manifestation of cancer, it thus becomes mandatory to study the role of this potent oncogene in relation to the processes of cell survival, death and functioning.

Abstract
Enzymatic and non-enzymatic antioxidants serve as an important biological defense against environmental oxidative stress. Information on antioxidant defense in fish is meager despite that fish are constantly exposed to a myriad of environmental stress including the oxidants. This study, therefore, assesses the activities of antioxidant enzymes viz., glutathione peroxidase, catalase and glutathione S-transferase and the non-enzymatic antioxidants viz., glutathione and metallothionein in various tissues of freshwater fish Channa punctatus (Bloch), in response to short-term and long-term exposures to paper mill effluent. The fish were exposed to the effluent at a concentration of 1.0% (v/v) for 15, 30, 60 and 90 days. The exposure caused a time-dependent increase in glutathione level (P < 0.001), activities of glutathione peroxidase (P < 0.05 to P < 0.001), glutathione S-transferase (P < 0.001) and a marginal initial decrease in catalase activity in the liver (P < 0.01 to P < 0.001). Metallothionein was induced in liver after 60 days of exposure. Two isoforms of metallothionein were detected. Catalase activity also increased 60 days afterwards. Antioxidant pattern was different in gill and kidney showing that liver was more resistant to oxidative damage as compared to gills and kidney. Our results demonstrate a pollutant-induced adaptive response in fish. In addition, levels of enzymatic and non-enzymatic tissue antioxidants may serve as surrogate markers of exposure to oxidant pollutants in fish.
