Acute pericarditis and pericardial effusion are rare extrapulmonary presentations of COVID-19. They can occur without concomitant pulmonary disease or myocardial injury. A high index of suspicion is necessary to assure early diagnosis and treatment.

Introduction. Tetanus is still a major health issue, especially in rural areas, and is associated with high morbidity and mortality rate. This study was conducted to describe the pattern of presentation and treatment outcome among adult patients infected with tetanus in our environment. Materials and Methods. This is a descriptive retrospective hospital-based study conducted in Wad Medani teaching hospital, central Sudan. A total of thirty-one patients were enrolled in this study in the period between January 2018 and December 2020. Results. Thirty-one patients were infected with tetanus during the study period. They were 23 (74.2%) males and 8 (25.8%) females with a male-to-female ratio of 2.875 : 1. Their ages ranged from 20 to 70 years, and most of them (48.4%) were free workers. Acute injuries were the most common portal of entry (64.51%), and commonly involved the lower limbs (48.38%). Lock jaw (54.8%), muscle spasm (51.6%), and neck pain and stiffness (45.2%) were the most common presentation. Supportive measures along with surgical toilet and debridement, human tetanus immunoglobulin, antibiotics, and muscle relaxants were initiated in all patients. The most common antibiotics used were Penicillin V and Ceftriaxone. A muscle relaxant was administered to aid in relieving the spasms. Complication rate was 61.29% and included pulmonary and cardiovascular complications. Fifteen patients died accounting for an overall mortality rate of 48.4%. Conclusions. Tetanus remains a disease with high morbidity and mortality. The unknown/incomplete vaccination status among study participants, inadequate management, and lack of equipped resources lead to a devastating outcome as in Sudan.

Frank’ sign or diagonal earlobe crease (DELC) is a diagonal earlobe crease that extends backwards from the tragus at an angle of 45 degree across the lobule to the ear edge of the auricle. It has been described as a dermatological marker for coronary artery disease. Frank’s sign is a useful clinical sign for coronary artery disease. Inspection of the earlobes should be considered as integral part of the physical examination in clinical practice for patients with suspected coronary artery disease.

Background. Hereditary hemorrhagic telangiectasia (HHT) also known as Osler–Weber–Rendu syndrome is a rare autosomal dominant disorder, which results in vascular dysplasia affecting mainly visceral and mucocutaneous organs. Case Presentation. A 65-year-old woman with a 12-year history of recurrent spontaneous epistaxis presented with shortness of breath, easy fatigability, and bilateral lower limb edema. Her family history was significant for definite hereditary hemorrhagic telangiectasia in first-degree relatives. During the previous 15 days, she has experienced three episodes of recurrent nasal bleeding. She has a background of chronic mitral regurgitation. Physical examination revealed telangiectases in her tongue, lower lip, and hand in addition to signs of congestive heart failure. The patient met 3\4 Curacao criteria and had a definite HHT. Her laboratory workup revealed a hemoglobin count of 5.4 g/dl. Echocardiography revealed a left systolic ejection fraction of 51% with left atrial dilatation and severe mitral regurgitation. Chest X-ray showed features of cardiomegaly and pulmonary edema. The abdominal ultrasonography showed enlarged liver size with homogenous texture and congested hepatic veins without features of hepatic AVMs. She was treated with intravenous frusemide, iron supplement, tranexamic acid, blood transfusion, and nasal packing. Conclusions. HTT usually passes unnoticed in Sudan. The rarity of HHT, difficulties in affording diagnostic imaging studies, and low clinical suspicion among doctors are important contributing factors. Anemia resulting from recurrent epistaxis might have an influential role in precipitating acute heart failure in those with chronic rheumatic valvular disease.
