Objective: To describe the pattern of septicaemia among sickle cell anaemia patients.
Design: Descriptive study.
Setting: Haematology Day Care Unit of the University College Hospital, Ibadan, Nigeria.
Subjects: 269 patients with sickle cell anaemia who presented with fever greater than 38 degrees C.
Results: The blood of 97 of the patients exhibited positive growth with isolation of bacteria thereby confirming the diagnosis of septicaemia in them. Fifty seven (59%) of the isolates were gram negative while 40 (41%) were gram positive pathogens. Klebsiella sp. was the predominant gram negative bacteria while Staphylococcus aureus was the predominant gram positive bacteria. The sensitivity tests on the isolates confirmed Ceftozidine (Fortum) was the most effective antibacterial agent for the gram negative and gram positive pathogens. The 172 patients, who had no bacteria pathogens isolated did well with prophylactic broad spectrum antibiotics. Thirty one patients with positive malarial parasites had full anti-malarial therapy.
Conclusion: The incidence of gram negative septicaemia is high in patients with sickle cell anaemia. Klebsiella spp. is the predominant gram negative bacterium while Staphylococcus aureus is the predominant gram positive bacterium. Ceftozidine appears to be the most effective antibiotic against both the gram positive and gram negative bacterial infection.

Uncontrollable haemorrhage and associated microbial contamination in the battlefield and civilian injuries pose a tremendous threat to healthcare professionals. Such traumatic wounds often necessitate an effective point-of-care solution to prevent the consequent morbidity owing to blood loss or haemorrhage. However, developing superior hemostatic materials with anti-infective properties remains a challenge.

Background: With the rising prevalence of obesity, surgeons are frequently confronted with the problem of treating osteoarthritis of the hip via arthroplasty (total hip arthroplasty) in severely obese patients. To reduce the surgical impact, minimal-invasive approaches are often chosen. For this reason, the direct anterior approach has gained popularity but is suspected of leading to more wound complications in obese patients, especially by Gram-negative pathogens.

Shoulder abscesses, commonly resulting from bacterial infections, can occasionally present with atypical etiologies and delayed onset. We report a rare case of a massive polymicrobial shoulder abscess developing two decades after an insect bite, emphasizing its clinical presentation, diagnostic approach, and surgical management. A 65-year-old female presented with severe, progressively worsening right shoulder pain, a 20 cm swelling, and purulent discharge persisting for 15 days.
