Pneumonectomy in a Child with Multilobar Pneumatocele Secondary to Necrotizing Pneumonia: Case Report and Review of the Literature
Background. Community-acquired pneumonia (CAP) is common within pediatrics and contributes disproportionately to morbidity and mortality. Necrotizing pneumonia is a well-documented complication of CAP. It is thought to be caused by necrosis and liquefaction of consolidated lung and can result in damage to lung parenchyma, including pneumatocele development. Management of necrotizing pneumonia with pneumatocele may include hospitalization, intensive care unit admission, and lengthy antibiotic courses....

Ten-Year Follow-Up of Collision Tumors Composed of Craniopharyngioma and Pituitary Adenoma: A Case Report and Literature Review
Although craniopharyngioma (CP) and pituitary adenoma (PA) are common tumors of the parasellar lesions, the coexistence of CP and PA is very rare. A 48-year-old male visited our hospital because of consciousness disturbance. The neuroimaging revealed a sellar tumor contact with a massive suprasellar cyst including calcification. Preoperative diagnosis was CP, and the patient underwent craniotomy to resolve the suprasellar mass effect. The histological examination disclosed adamantinomatous CP, and...

Renal failure caused by severe pelvic organ prolapse
Pelvic organ prolapse (POP), the transvaginal descent of pelvic organs, can cause mild hydronephrosis but rarely leads to a deterioration in kidney function. We present a case of severe uterovaginal prolapse that caused bilateral ureteral obstruction and led to renal failure and urinary tract infection. During outpatient follow-up, kidney function had already been deteriorating, but POP was not recognised as a causal factor. A longer duration of ureteral obstruction can lead to irreversible kidney...

A rare case of long-term paraesthesia diagnosed as a paraneoplastic syndrome by anti-SOX1 antibody determination
Paraneoplastic syndromes (PS) are a rare presentation of cancer, most commonly associated with small cell lung cancer (SCLC), breast cancer and haematologic malignancies. The diagnosis of PS is challenging because it could affect multiple organ systems and it may present before the tumour is visible by imaging. We report a malignant tumour diagnosed in a male patient who referred long-term paraesthesia and proximal muscle strength loss. After ruling out common causes of polyneuropathy, the anti-SOX1...

A Rare Association between Myasthenia Gravis and a Growth Hormone Secreting Pituitary Macroadenoma: A Single Case Report
AbstractMyasthenia Gravis (MG) is a chronic autoimmune neuromuscular disease. Although it is well known that patients with myasthenia gravis have a higher incidence of other autoimmune disorders, however, its association with pituitary adenomas is extremely rare. We believe that our case represents the 8th of this association and the 2nd case involving a GH-secreting adenoma. Here we report a case of a 45-year old Syrian woman who presented with typical complaints of myasthenia gravis as she was...

Primary intestinal lymphangiectasia in a 23-month- old girl
AbstractPrimary intestinal lymphangiectasia (PIL) is a rare protein-losing gastroenteropathy which is defined as dilation of existing mucosal, submucosal, or subserosal lymphatics within the gastrointestinal tract. That causes loss of lymph fluid into the gastrointestinal tract, leading to the development of hypoproteinemia, edema, lymphocytopenia, hypogammaglobinemia, and immunologic anomalies. It is usually diagnosed in patients younger than 3 years old and is rarely first diagnosed in adulthood....

Colonic metastases 13 years after the primary ovarian cancer: a case study with a brief review of literature
Metastatic ovarian malignancy is a known and dreaded complication of ovarian malignancy. Ovarian malignancies primarily disseminate through the peritoneal cavity and are only superficially invasive. They rarely metastasise through the haematogenous route, but that occurs in the presence of heavy peritoneal disease. The involvement of the colon in advanced ovarian malignancy is mostly through the peritoneal seedlings. It is very rare for an ovarian malignancy to invade through the serosa into the...

 Periorbital dermatitis in patients receiving docetaxel in combination chemotherapy,
Recognition of new cutaneous side effects of combination chemotherapy can help prevent unnecessary cessation or reduction of cancer therapy. Periorbital rash has not been found with docetaxel alone, but here, we report it as a result of combination chemotherapy. A series of three patients who received docetaxel in combination with other chemotherapies developed clinically near-identical, distinctive periorbital rashes. Rashes resolved by resolving underlying docetaxel-induced epiphora in conjunction with ophthalmological consultation, topical skin-directed care, and in some cases, chemotherapy dose reduction. It is important for dermatologists and oncologists to recognise the increased severity of cutaneous reactions when docetaxel is used in combination chemotherapy.

Rituximab as Rescue Therapy for Aggressive Pediatric Multiple Sclerosis
Multiple sclerosis is a chronic, debilitating disease. Almost one in ten patients with MS has a history of disease onset during childhood. Although numerous therapeutic options exist for adult MS, the available treatments for pediatric patients are still limited. One of the emerging therapies is rituximab, a monoclonal anti-CD20 chimeric antibody that can deplete the CD20+ lymphocyte populations. A 12-year-old boy presented with ataxia, paresthesias, and headache while his brain MRI showed numerous...

Vascular and neural basis of the BOLD signal
Publication date: October 2019Source: Current Opinion in Neurobiology, Volume 58Author(s): Patrick J DrewNeural activity in the brain is usually coupled to increases in local cerebral blood flow, leading to the increase in oxygenation that generates the BOLD fMRI signal. Recent work has begun to elucidate the vascular and neural mechanisms underlying the BOLD signal. The dilatory response is distributed throughout the vascular network. Arteries actively dilate within a second following neural activity...

Researchers Keep Rejecting Grandmother Cells after Running the Wrong Experiments: The Issue Is How Familiar Stimuli Are Identified
Grandmother cells constitute a hypothesis of how familiar visual categories are identified, but the primary evidence against them comes from studies that have assessed how neurons respond to unfamiliar visual categories. This review summarizes the existing research and shows that grandmother cells are consistent with current evidence. There is widespread agreement in neuroscience and psychology that the visual system identifies objects and faces based on a pattern of activation over many neurons,...

Abstract
The purpose of this study was to evaluate the skeletal units of a normal mandible (class I) and a prognathic mandible (class III), to compare the groups, and to investigate the key functional unit responsible for mandibular prognathism. Hemi-mandibles of 101 cases were evaluated by cone-beam computed tomography. Of these, 50 cases had Class I and 51 had Class III mandibles. The length, volume, and volume/length ratio of each skeletal unit were measured. The ratios of the condyle, body unit, and sum of the hemi-mandible between Class I and Class III showed statistically significant results (P < 0.05). However, the ratios of angle, coronoid, and symphysis units did not show any statistical significance on comparison. Dependent on gender, in males the ratio of the condyle of the hemi-mandible showed statistically significant results (P < 0.05). Meanwhile in females the ratio of the body and sum of the hemi-mandible showed statistically significant results (P < 0.05). Accordingly, the mandibular body and condylar units are thinner in mandibular prognathism. On the basis of the functional matrix theory to determine the etiology of mandibular prognathism, the key skeletal units are the body and condylar units.
