Severe Rhabdomyolysis Complicated With Acute Kidney Injury Required Renal Replacement Therapy After Pfizer COVID-19 Vaccine  .

The adverse effects of coronavirus disease 2019 (COVID-19) vaccines are somewhat common but rarely life-threatening. Diagnosing life-threatening vaccine-related adverse effects is heavily dependent on history taking and ruling out the other possible causes. Vaccine-related complications vary, so awareness of possible complications can lead to efficient management. We present the case of a 58-year-old woman with a history of schizophrenia who received the COVID-19 Pfizer vaccine and developed severe rhabdomyolysis. She required renal replacement therapy and fully recovered with possible transient autoimmune activity. This case highlights the importance of early awareness of adverse effects following vaccine administration and careful history taking and monitoring to avoid life-threatening conditions.

Vibrio cholera Bacteremia Secondary to Ascending Cholangitis in a Patient Not on Chemotherapy or Immunosuppressants.

Non-O1, non-O139 Vibrio cholera (NOVC) are considered non-pathogenic organisms, but in some cases, it is known to be responsible for self-limiting intestinal and extra-intestinal infections in immunocompetent individuals. On the other hand, NOVC bacteremia affects mainly immunocompromised patients with significantly high mortality rates. We report a case of an 80-year-old female with a 20-year history of multiple abdominal surgeries. She is also known to have ischemic heart disease and atrial fibrillation. The patient presented with abdominal pain and signs of septic shock. Her abdominal imaging showed features of ascending cholangitis, while her blood culture grew V. cholera. She was discharged after completing the course of antibiotics but then came back with a similar presentation. The repeated blood culture showed Clostridium perfringens, while other cultures were negative. The patient's condition worsened due to sepsis, and she passed away. NOVC bacteremia is a fatal disease even in hosts who are not receiving immunosuppressants or chemotherapy. It may present without a history of diarrhea or seafood ingestion. In such situations, abdominal imaging is necessary to identify the presence of intra-abdominal infections.

Herpes Zoster Co-Infection in an Immunocompetent Patient With COVID-19.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has a broad spectrum of manifestations. A variety of dermatological manifestations were described. We present a case of an immunocompetent middle-aged man who presented with novel coronavirus disease 2019 (COVID-19) and later developed herpes zoster (HZ). The case highlights the possibility of COVID-19-related HZ. The highest infection control measures must be abided when managing patients with cutaneous complaints until COVID-19 is ruled out.

Genetic diversity among natural populations of Schistosoma haematobium might contribute to inconsistent virulence and diverse clinical outcomes.

There is an evident difference in the intensity of morbidity caused by Schistosoma haematobium in North-African zones compared to Sub-Saharan ones. Clinical outcome dichotomy corresponds to two geographically distinct intermediate host snail species that are only infected by the related strain of the parasite. In concert, there is a manifest hybridization of the parasite with other Schistosoma species confined to certain regions of Africa. This raises a reasonable suggestion that S. haematobium has no less than two phylogenetic clusters that have different virulence. The aim of the study was to examine the possible diversity among S. haematobium using simultaneous amplification of genomic DNA of selected isolates. Random amplified polymorphic DNA-polymerase chain reaction markers were used to study the genetic diversity among S. haematobium natural isolates from selected regions of Africa (Egypt, Zimbabwe, and South Africa) that represent different ecological conditions, different species of intermediate host, and different possibilities of field hybridization with other schistosomes. A moderate to high level of genetic diversity was evident among the three isolates. More bands were shared by the isolates from Zimbabwe and South Africa (similarity index = 0.721) than those shared by each with the Egyptian isolate (similarity index = 0.551 and 0.566, respectively), suggesting that at least two phylogenetic groups of S. haematobium do exist in distinct geographic regions of Africa. The elucidation of the possible genetic diversity among S. haematobium parasites may explain many ambiguous aspects of the biology of the parasite-like virulence, immune evasion and drug resistance.
