COVID-19 vaccine response in Neuromyelitis Optica Spectrum Disorder.

Objectives And Aims: Neuromyelitis Optica Spectrum Disorder (NMOSD) is a disabling autoimmune disease of the central nervous system that requires immunosuppressants to control the relapses. The latter puts them at risk for more severe COVID-19 infection. Vaccines are an effective way to control the pandemic.

Impact of the 3rd Edition of the Bethesda System for Reporting Thyroid Cytopathology on Grey Zone Categories.

Introduction: Thyroid Bethesda Reporting System is a six-tiered system that aims to bring uniformity in reporting thyroid cytology and improve the communication with clinicians. The system has achieved its goal as a presurgical diagnostic method; however, it remains a screening method in the grey zone categories, namely atypia of undetermined significance (AUS) and follicular neoplasm (FN). The book recently released the 3rd edition, following the recent changes in thyroid pathology.

The Role of Telecytology in the Primary Diagnosis of Thyroid Fine-Needle Aspiration Specimens.

Introduction: The Acibadem Health Group (AHG) has been using telepathology/digital pathology stations since 2006. In 2013, the system was changed from videoconferencing to digital pathology (whole-slide imaging) utilizing 3DHISTECH scanners and software. In 2017, digital cytology started to be used for routine cytopathologic diagnosis for thyroid fine-needle aspiration (FNA) cases.

The new guidelines of Papanicolaou Society of Cytopathology for respiratory specimens: Assessment of risk of malignancy and diagnostic yield in different cytological modalities.

Background: In 2016, the Papanicolaou Society of Cytopathology (PSC) issued a new classification scheme for respiratory cytology. We aim to evaluate our samples according to this classification and to assess risk of malignancy and diagnostic yield of different cytological modalities.

Methods: Respiratory specimens (sputum, bronchial wash/brush, BAL and FNA) obtained between 2007 and 2016 were reclassified according to PSC guidelines.

[Amoebic liver abscess in a patient initially diagnosed with pneumonia: case report and discussion of relevant literature].

In one-third of the patients with amoebiasis, amoebic liver abscess (ALA) may occur after the penetration of amoebic trophozoites through the intestinal wall. ALA is seen mostly among men aged 20-45 years with a serious clinical outcome, with fever and abdominal pain on the right upper quadrant. Most patients have no recent history of amoebic colitis; indeed, they have neither gastrointestinal complaints nor Entamoeba histolytica (E.

Endovenous 1470 nm laser treatment of the saphenous vein: early report of pain assessment.

Aim: The aim of the paper was to evaluate the rate of postoperative pain by using endovenous laser ablation with wave-length of 1470 nm for incompetent saphenous veins in our single center experience.

Methods: A non-randomized prospective trial was performed. Patients with symptomatic varicose small saphenous vein and great saphenous vein were considered suitable for endovenous laser ablation.

Diagnosis in childhood abdominal Burkitt's lymphoma.

Background: The role of surgery has changed substantially over the years in abdominal Burkitt's lymphoma. Laparotomy without total excision of the tumor does not have a positive effect on survival, might cause complications, and delays initiation of chemotherapy. Here we present our diagnostic management of patients with abdominal Burkitt's lymphoma.

Paraneoplastic porphyria cutanea tarda associated with cholangiocarcinoma: case report.

The porphyrias are a group of disorders of the heme biosynthesis pathway that present with acute neurovisceral symptoms, skin lesions or both. Porphyria cutanea tarda, presenting as a non-acute form, is the most common type of porphyria that encompasses a group of related disorders, all of which arise from deficient activity of the heme synthetic enzyme, uroporphyrinogen decarboxylase, in the liver. In the literature, concomitant presentation of porphyria with hepatocellular carcinoma is common; however, no case of porphyria cutanea tarda associated with cholangiocarcinoma has been seen.

[Acute lymphoblastic leukemia presenting with multiple hemorrhagic brain metastases (case report)].

Intracranial metastases represent 7-17% of all brain tumors. Renal cell carcinoma, thyroid cancer, choriocarcinoma, melanoma, retinoblastoma, lung cancer and breast cancer have a propensity for producing hemorrhagic brain metastases. Leukemias have also been rarely reported to cause hemorrhagic brain metastases.
