Sclerosing Encapsulating Peritonitis Following Recovery From COVID-19 Pneumonia.

Coronavirus disease 2019 (COVID-19) is primarily a respiratory illness and pulmonary manifestations are the typical presentations of the disease. However, it became evident that the COVID-19 is not limited to the respiratory system. Specifically, gastrointestinal involvement in patients with COVID-19 is very common, particularly in patients with a critical illness. We present a case of a 52-year-old man who was diagnosed as having severe COVID-19 pneumonia and underwent endotracheal intubation and mechanical ventilation. The patient remained in the intensive care unit for seven days. Following his recovery, he started to experience generalized abdominal pain. The pain did not resolve with conservative measures. A computed tomography scan of the abdomen demonstrated small bowel loops clustered with a surrounding thin membrane. Such findings conferred the diagnosis of sclerosing encapsulating peritonitis. The patient was prepared for laparoscopic surgery. Resection of the membrane was performed without any injury to the encapsulated bowel. Analysis of peritoneal fluid by reverse transcription-polymerase chain reaction (RT-PCR) was positive for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The patient had an uneventful recovery. Sclerosing encapsulating peritonitis is a very rare condition associated with COVID-19 pneumonia. The present case is the first reported case to document the presence of the SARS-CoV-2 virus in the peritoneal fluid in a patient with sclerosing encapsulating peritonitis.

The Association of Blood Glucose Levels and Arterial Stiffness (Cardio-Ankle Vascular Index) in Patients With Type 2 Diabetes Mellitus.

INTRODUCTION:  Diabetes mellitus causes a major burden on healthcare systems all around the world. It has been documented that type 2 diabetes mellitus (T2DM) is associated with long-term vascular complications including micro-vascular, macro-vascular, and mixed-vascular disorders. Several studies have concluded that the increment of arterial wall stiffness is correlated with an increase in the risk of cardiovascular adverse events and the mortality associated with it. AIMS:  This study purposed to evaluate the arterial stiffness measurements, using Cardio-Ankle Vascular Index (CAVI), in T2DM patients, and the relationship with the fasting blood glucose (FBG), hemoglobin A1c (HbA1c), and other factors that may increase the risk of elevated arterial stiffness in T2DM patients. METHODOLOGY:  A total of 200 patients were recruited from the outpatient setting at King Fahd Hospital of the University, Al Khobar. A total of 181 patients fit the inclusion criteria. The charts of the patients who fit the inclusion criteria were reviewed and data related to age, gender, body mass index, smoking history, FBG, HbA1c levels, blood pressure (mmHg) measurements, and CAVI scores were collected. RESULTS:  The elevation in CAVI readings was noted to be more prominent in the senior age group. Hypertensive patients also showed a significant increase in CAVI readings. In addition, higher CAVI readings were more associated with the male gender rather than females. All of which showed a significant correlation. Furthermore, although it was not significant, higher FBG levels and HbA1c readings were correlated with higher CAVI readings. CONCLUSION:  The results of the study suggest that factors like age, smoking status, gender, and the increase in blood pressure as well as the increase in blood glucose levels are correlated with higher CAVI readings in T2DM patients. This demonstrates their important effect on arterial wall stiffness while showing that CAVI can be used in predicting the prognosis of arterial wall health in patients with diabetes.

Schwannoma: A Rare Etiology of Pancoast Syndrome.

Musculoskeletal disorders represent a major public health problem and they are frequently managed in primary care centers. Shoulder pain is a frequent musculoskeletal complaint and it can result from intrinsic disorders of the shoulder or referred pain. We present the case of a 24-year-old woman who presented to the family medicine clinic complaining of left shoulder pain for three months duration. The pain was not associated with numbness or weakness. There was no history of preceding trauma. The initial diagnosis was supraspinatus tendinosis. The patient was prescribed oral analgesics and was advised to undergo multiple physiotherapy sessions. Later, the patient presented to the clinic again and reported she did not have any improvement in her symptoms. The patient was referred to the orthopedic clinic for further evaluation and management. The patient underwent a frontal radiograph of the chest which demonstrated a well-defined opacity located in the apex of the left lung. A computed tomography scan of the chest demonstrated the presence of erosion to the vertebral body raising the suspicion for a neurogenic tumor as was later supported by magnetic resonance imaging. The patient underwent video-assisted thoracotomy with brachial plexus exploration. Complete resection of the tumor was achieved with no complications. The present case highlights those common musculoskeletal complaints, such as shoulder pain, which could indicate underlying non-orthopedic pathology.
