    Abstract Background: This study aimed to compare the effect of heat treatment on the cyclic fatigue resistance of three different nickel-titanium rotary file systems: TruNatomy, HyFlex CM, and NeoEndo flex in simulated curved canals at two different radii of curvatures.
    Materials and methods: A total of 60 NiTi rotary files of three types were used, and the samples were divided into three groups TruNatomy, HyFlex CM, and NeoEndo flex. All the instruments were subjected to cyclic fatigue testing using a stainless steel custom-made canal model with a 60° angle of curvature and two radii of curvature 5 mm and 3 mm; the number of cycles to fracture and length of the fractured segment was measured. The separated instruments were subjected to fractographic analysis under scanning electron microscope.
    Results: The number of cycles to failure to fracture a file at a 3 mm radius of curvature is significantly less as compared to a 5 mm radius of curvature (HCM > TRN > NE).
    Conclusion: Within the limitation of the present study, there was a positive correlation between the radius of curvature and fatigue life of NiTi files.

    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 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 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 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.
