Neurofibromatosis (NF) is an autosomal dominant genetic disorder with a prevalence of 1/3,000 births. The NF mutation causes multiple abnormalities of various cells of neural crest origin. Schwann cell tumors (neurofibromas, acoustic neuromas) are the most common feature of neurofibromatosis although meningiomas, gliomas, and other neoplasms may be seen. The schwann cell tumors commonly develop from the schwann cells associated with sensory or sympathetic nerves or their ganglia. Schwann cell tumors on ventral spinal roots or motor cranial nerves are much less common. Since the sensory neuron membrane is known to contain a mitogenic factor for schwann cells, we have postulated that neurofibromatosis may be due to an abnormal interaction between the nerve and the schwann cell and that this interaction may be hormonally modulated. To test this possibility a system has been developed in which an enriched schwannoma cell culture can be obtained and co-cultured with pure neurons.

The myelodysplastic syndrome-myeloproliferative neoplasms (MDS/MPNs) are defined by a group of heterogeneous hematological malignancies resulting from stem cell−driven clonal growth of pathological hematopoietic progenitors and ineffective hematopoiesis, they are characterized concomitant myelodysplastic and myeloproliferative signs. Myelodysplastic/myeloproliferative disorders have been considered to have a higher risk of thrombus formation.We report a rare case about a 64 years old Moroccan woman, experienced renal infarction (RI) associated with pulmonary embolism as a complication of a myelodysplastic/myeloproliferative disorder.The patient complained of acute-onset severe left flank pain, a contrast-enhanced computed tomography (CT) of the chest and abdomen revealed RI by a large wedge-shaped defect in the right kidney with pulmonary embolism.Biological exam showed deep anemia, the bone marrow aspiration found myelodysplasia.the bone biopsy showed signs of myeloproliferatif disease. The karyotype was normal, BCR-ABL, JAK2, CALR mutations were absents, and MPL mutation was positive. The International Prognostic Scoring System (IPSS-R) was 0, and the patient was included to the low risk group.Anticoagulation therapy was initiated with heparin to treat RI and pulmonary embolism. Three months later, pulmonary embolism had resolved without the appearance of additional peripheral infarction.This case emphasizes the need to consider myelodysplastic/myeloproliferative disorders as a cause of infraction renal and pulmonary embolism.

Omental infarct is a rare cause of an acute abdomen that arises from an interruption of blood supply to the omentum. Here, we present a case of omental infarct in a 67-year-old gentleman with background history of diabetes mellitus who present unusually with a severe acute onset right hypochondrium pain. Examination revealed that he was tender to touch at the right and was having localized guarding. His inflammatory markers were normal. He was successfully treated with laparoscopy surgery and he was subsequently discharged the following day. Omental infarct cases with right hypochondrium pain can sometimes mimicked acute cholecystitis and management includes laparoscopic surgery which can hasten symptoms resolution and reduces hospital stay, however recommendation for surgery has to be balanced with anesthetics risk and complication of the surgery itself.

Background: Hypoglycemia may rarely present as hemiparesis and sometimes it is difficult to differentiate from ischemic stroke. When random blood sugar (RBS) value is between 50 and 80 mg % in patients presenting with focal neurological deficit, no guideline exists to consider the possibility of hypoglycemia before initiating thrombolytic therapy. Clinical Case: A 58-year-old male, who was a known case of diabetes and hypertension, was brought to the emergency room with acute onset of right hemiparesis and dysarthria of 90 minutes duration. His NIHSS Score was 9, blood pressure was 150/90 mm of Hg and RBS was 79 mg% on admission. His CT scan brain was normal and was considered for thrombolysis. Resident doctor not aware of previous sugar repeated RBS before thrombolysis which was surprisingly 60 mg% 60 minutes after the first RBS. Even though he was a candidate for thrombolysis, intravenous 25 % dextrose was administered considering the possibility of hypoglycemia. He made a complete recovery within 20 minutes and thrombolytic therapy was withheld. : In Diabetic patients with focal neurological deficit and RBS less than 80 mg% on admission, RBS should be rechecked and in appropriate cases should be challenged with IV dextrose considering the possibility of hypoglycemia before commencing thrombolytic therapy.
