A Rare Combination of Arterial and Venous Thrombosis as a Sequalae of COVID-19.

Coronavirus disease 2019 (COVID-19) has been a devastating condition claiming millions of lives, crippling countless people, and causing economic turmoil all over the world since the outbreak started in Wuhan Province of China in December 2019. Numerous papers have been published in the literature about COVID-19-related complications affecting almost all systems in the human body. One of the severe complications of this disease is thromboembolism, which affects both the arterial and venous systems and is well documented. There are few reports about both arterial and venous system involvement in the same patient. Herein, we report the case of COVID-19, who presented with critical limb ischemia caused by both arterial and venous thrombosis.

A Rare Complication of Perforated Appendicitis: A Case of Necrotizing Fasciitis.

Acute appendicitis is considered one of the most common surgical emergencies with low morbidity and mortality. However, delay in the diagnosis may lead to perforation of the appendix. Hence, complications may arise, including necrotizing fasciitis, a rare complication of a perforated appendix. We present a case of perforated appendicitis complicated by necrotizing fasciitis leading to rapid deterioration. A 75-year-old male patient presented to our emergency room with a three-day history of right lower quadrant abdominal pain and abdominal distention. On admission, computed tomography (CT) scan showed a perforated appendix and peri-appendicular abscess. An exploratory laparotomy was performed. The appendix was resected and the wound closed. The patient was recovering well and tolerating food after the procedure. However, the patient developed progressive erythema/swelling over the right flank with new-onset leukocytosis. The diagnosis of necrotizing fasciitis was suspected and confirmed by careful evaluation and laboratory/radiological tests. Antibiotics were changed to clindamycin and piperacillin/tazobactam, and the patient was taken back to the operation room (OR) for surgical debridement. Postoperatively, the patient was shifted to the intensive care unit (ICU). He developed hearing impairment, which improved after the cessation of clindamycin. He was discharged in good condition after three weeks of hospital stay. This case report highlights the importance of maintaining a high index of suspicion for necrotizing soft tissue infection in immunocompromised patients with perforated appendicitis and being cautious when prescribing clindamycin to patients at risk of hearing loss.

ESBL expression and antibiotic resistance patterns in a hospital in Saudi Arabia: Do healthcare staff have the whole picture?

BACKGROUND: We analyse the distribution of ESBL infections in Dammam Medical Complex, Eastern Province, Saudi Arabia with respect to patient demographics, wards, infection site, bacterial species, and antibiotic resistance. We also gauged hospital staff understanding of ESBLs, the procedures in place to identify, treat and infections containing. METHODS: Hospital records from 2016 were analysed and 352 ESBL from several samples types were identified using VITEK® 2 system and by phenotypic confirmation using a disk diffusion test. HCWs attitudes and knowledge were assessed using a paper questionnaire. RESULTS: The percentage of ESBL isolates were Klebsiella pneumoniae(n=148; 42.1%) or Escherichia coli(n=176; 50%), Proteus mirabilis(n=7; 2%), Morganella morganii(n=13; 3.7%), Enterobacter (n=7; 2%) and Citrobacter freundii (n=1; 0.3%). Overall tigecycline susceptibility was 82.2%, however P. mirabilis and M. morganii isolates were uniformly resistant and K. pneumoniae susceptibility levels were significantly lower than for E. coli in urine samples (72.3% v 100%; Chi square=13.76, p=0.0002); for blood samples there was also apparently higher resistance among K. pneumoniae isolates. Overall susceptibility to the carbapenems imipenem, meropenem and ertapenam was high. There were overall high levels of uncertainty among healthcare workers on hospital policies on reporting or prescribing with respect to ESBL-expressing infections. CONCLUSIONS: ESBL control strategies should consider variations among sample types, wards, and antibiotic resistance variability. There is a need to specifically address staff training and communication procedures for infection prevention and control with respect to ESBLs.
