Measurement of brachial artery endothelial perform employing a regular blood pressure levels cuff.
Metastatic neuroendocrine tumours (NETs) to the breast are very rare entities.

A 26-year-old lady presented with anterior neck swelling with symptoms of superior vena cava syndrome for 6 months. Imaging study revealed a mediastinal mass which was preceded with core biopsy which was consistent with high-grade small cell NETs. Despite second-line adjuvant chemotherapy and radiotherapy, her disease became advanced which was confirmed via restaging scan. There were bilateral breast lesions discovered during the scan which was deemed to be metastatic NETs histologically. Despite prompt initiation of treatment, she succumbed 1 year after the radiotherapy due to disease progression.

High suspicion of an index is needed for diagnosis when patients with known primary NETs present with suspicious breast lesions. Triple assessment is mandatory, however histopathology assessment and immunohistochemistry staining are the mainstay of diagnosis.

Cerebral salt wasting syndrome (CSWS) is a cause of hyponatremia in the setting of intracranial pathologies such as Central Nervous System (CNS) trauma, infections, and tumors. It is important to differentiate CSWS from the syndrome of inappropriate antidiuretic hormone secretion (SIADH) as their management differs. CSWS leads to hypovolemia as opposed to euvolemia or hypervolemia in SIADH. SIADH is managed with fluid restriction and this could worsen CSWS which is managed with adminstration of intravenous crystalloids to correct hyponatremia.

A 42-year-old male was admitted after a week of low-grade fever with easy fatigability, hypersomnolence, and excessive thirst. He had polyuria which started 5 days before presentation, and unintentionally lost 3kg of weight in the past month. He had orthostatic hypotension, and was dehydrated, but vital signs were normal with the exception of his temperature. Cerebrospinal fluid (CSF) analysis revealed a glucose of 42 mg/dl, protein 170 mg/dl, cell count 28/mm
witarly diagnosis and treatment has an excellent prognosis, but any delay contributes to death and disability despite anti-tubercular drug therapy.CSWS should be managed with salt and volume replacement, but more importantly, the causative CNS insult should also be confirmed and addressed.
Routine histopathological examination (RHPE) of all gallbladder specimens is required to detect the presence of gallbladder carcinoma (GBC) or any other pathology. The work aims to study the incidence and the clinical significance of detecting unusual gallbladder findings upon the RHPE of the referred cholecystectomy specimens to a histopathology laboratory section at a referral hospital in Saudi Arabia during one year period.

From May 2019 to May 2020, all histopathology reports of 444 consecutive gallbladder specimens after elective and emergency cholecystectomies were retrospectively analyzed and divided into two groups; usual findings and unusual findings which were reviewed blindly by two other pathology consultants. Frequencies, descriptive statistics, normality test, and correlations were run. The Interrater reliability between clinical and histopathological diagnosis was assessed statistically by kappa test.

The results of histopathological examination of these gallbladder specimens showed that chronic cholecystitis was found in 296 out of 444 total cases (66.7%), acute cholecystitis in 52 cases (11.7%), and other associated usual findings in 85 cases (19%). Three cases (0.7%) of incidental carcinomas and other three cases (0.7%) of dysplasia. Eosinophilic carcinomas were detected in two cases (0.45%), gallbladder complete septum was found in one case, and one case of Phrygian cap anomaly. All patients with gallbladder carcinoma were diagnosed incidentally during the histopathological examination.

RHPE of cholecystectomy materials are required to confirm the final diagnosis and document any other pathology. Failure to detect incidental occult carcinoma may be catastrophic, given the poor prognosis.

There is abundance of literature regarding the treatment of tibial mid-shaft fracture, and intramedullary nailing (IMN) is described as the treatment of choice. However, problems such as malunion and knee pain are known disadvantages of this approach. Minimally invasive plate osteosynthesis (MIPO) technique is another treatment option for tibial mid-shaft fracture.The purpose of this study is to evaluate the clinical, radiological results, and complication rates of tibial mid-shaft fractures treated with MIPO technique.

Thirty-seven skeletally mature patients who underwent MIPO for a mid-shaft fracture of tibia (AO/OTA classification 42) from June 2016 to May 2018 were retrospectively reviewed. A total of 37 patients (12 females, 25 males) with a mean age of 52.7 years (range 28-78 years) were included. The clinical and radiological outcomes, such as the Jeju Lower Extremity Trauma Scale (JLETS), time to callus formation, time to bony union, and complications such as delayed union, malunion, nonunion, andFuture study should aim to compare MIPO and IMN cases directly to clarify the differences and similarities between the two treatment modalities.Transitioning from in-person to remote learning can present challenges for both the instructional team and the students. Here, we use our course "Biodiversity in the Age of Humans" to describe how we adapted tools and strategies designed for a flipped classroom to a remote learning format. Using anonymous survey data collected from students who attended the course either in-person (2019) or remotely (2020), we quantify student expectations and experiences and compare these between years. We summarize our experience and provide ten "tips" or recommendations for a transition to remote learning, which we divide into three categories (a) precourse instructor preparation; (b) outside of class use of online materials; and (c) during class student engagement. The survey results indicated no negative impact on student learning during the remote course compared to in-person instruction. We found that communicating with students and assessing specific needs, such as access to technology, and being flexible with the structure of the course, simplified the transition to remote instruction.
