Puzzling encounter of idiopathic pasteurella bacteraemia.

Pasteurella multocida is a gram-negative coccobacillus that is commonly transmitted through animal bites including cats and dogs. The degree of infection can be worrisome in the immunosuppressed population with a stark correlation in patients with cirrhosis. However, taking that population into account, only 13 cases of P. multocida bacteraemia have been recorded with the majority of those cases having cirrhotic liver disease along with multiple comorbidities. Here, we present an elderly patient with only pertinent medical history of mixed hyperlipidaemia who presents after a mechanical fall with acute renal failure and septic shock secondary to P. multocida bacteraemia.

Antimalarial prophylaxis failure: Malaria in a returning traveler despite mefloquine prophylaxis.

This case report presents a perplexing case of Plasmodium malariae breakthrough infection despite prophylaxis with appropriate antimalarial prophylactic regimen of mefloquine in a compliant patient. A 78-year-old missionary who travels each year to the African subcontinent for multiple weeks to months, over 25 years, adheres to stringent antimalarial prophylaxis with Mefloquine as prescribed, starting prior to the trip and continuing after the return to the U.S.A. She gave no prior history of malaria during her 25 years of travel to Africa and back. Since she had no prior history of malaria and due to her excellent compliance with antimalarial regiment, despite her presentation which were suggestive of malaria, neither the patient nor her providers recognized the onset of malaria in this case. Infectious diseases physicians approached this case with an open mind, investigated appropriately, requested appropriate tests, found the presence of malarial parasite, identified as P. malariae species thereafter. She was started on antimalarial treatment in a timely fashion and showed an excellent response. This intriguing recovery of malarial parasite and response to treatment despite the patient being on antimalarial prophylaxis raised the possibility of mefloquine failure as an antimalarial prophylactic agent against P. malariae species.

Clinical outcomes of selective plantar fascia release for hallux interphalangeal joint ulcers.

BACKGROUND: Plantar hallux IPJ ulcers are common and challenging to manage, with many available treatments. One newer technique called SPFR has been used in the management of plantar forefoot ulcers. OBJECTIVE: This case series reports the clinical results of SPFR for treatment of strictly plantar hallux IPJ ulcers. MATERIALS AND METHODS: A retrospective chart review was conducted on patients that underwent SPFR procedure by a single foot and ankle surgeon from 2018 to 2023. The primary study outcome was to identify the rate and time of healing associated with SPFR for hallux IPJ ulcers. Only the initial surgery was evaluated for time of healing for the ulcer, healing rate, and complications. Subsequent surgeries were reviewed as well. Patient charts were further reviewed to determine the presence or absence of a postoperative complication. RESULTS: A total of 17 feet from 17 patients were studied. The hallux IPJ ulcers healed in an average of 3.0 months. The average follow-up time was 26.9 months. Fifteen patients (88.2%) healed after the SPFR procedure. Five patients (29.4%) developed transfer lesions, and 7 patients (41.2%) developed postoperative complications. CONCLUSIONS: The authors believe that SPFR can be utilized in the treatment of hallux IPJ ulcers if both surgeons and patients are aware of the potential complications and limitations of this procedure. Further research is warranted to evaluate the efficacy and reproducibility of these results.

Case report: Hospital-acquired chickenpox in a healthcare setting.

Chickenpox (varicella) is a rare occurrence in healthcare settings in the USA, but can be transmitted to healthcare workers (HCWs) from patients with herpes zoster who, in turn, can potentially transmit it further to unimmunized, immunosuppressed, at-risk, vulnerable patients. It is uncommon due to the inclusion of varicella vaccination in the recommended immunization schedule for children and screening for varicella immunity in HCWs during employment. We present a case report of hospital-acquired chickenpox in a patient who developed the infection during his prolonged hospital stay through a HCW who had contracted chickenpox after exposure to our patient's roommate with herpes zoster. There was no physical contact between the roommates, but both patients had a common HCW as caregiver. The herpes zoster patient was placed in airborne precautions immediately, but the HCW continued to work and have physical contact with our patient. The HCW initially developed chickenpox 18 days after exposure to the patient with herpes zoster, and our patient developed chickenpox 17 days after the HCW. The timeline and two incubation periods, prior to our patient developing chickenpox, indicate transmission of chickenpox in the HCW from exposure to the herpes zoster patient and subsequently to our patient. The case highlights the potential for nosocomial transmission of chickenpox (varicella) to unimmunized HCWs from exposure to patients with herpes zoster and further transmission to unimmunized patients. Verification of the immunization status of HCWs at the time of employment, mandating immunity, furloughing unimmunized staff after exposure to herpes zoster, and postexposure prophylaxis with vaccination or varicella zoster immunoglobulin (Varizig) will minimize the risk of transmission of communicable diseases like chickenpox in healthcare settings. Additionally, establishing patients' immunity, heightened vigilance and early identification of herpes zoster in hospitalized patients, and initiation of appropriate infection control immediately will further prevent such occurrences and improve patient safety.This is a case report of a varicella-unimmunized 31-year-old patient who developed chickenpox during his 80-day-long hospitalization. He had different roommates during his long hospital stay but had no physical contact with them and neither had visitors. On most days, the same HCW rendered care to him and his roommates. One of the patient's roommates was found to have herpes zoster and was immediately moved to a different room with appropriate infection prevention measures. The HCW is presumably unimmunized to varicella and sustained significant exposure to the patient with herpes zoster during routine patient care which involved significant physical contact. The HCW was not furloughed, assessed for immunity, or given postexposure prophylaxis (PEP). The HCW had continued contact with our patient as part of routine care. On day 18, after exposure to the patient with herpes zoster, the HCW developed chickenpox. 17 days thereafter, our patient developed chickenpox. The time interval of chickenpox infection in the HCW after one incubation period after exposure to the patient with herpes zoster followed by a similar infection of chickenpox in our patient after another incubation period suggests the spread of varicella zoster virus (VZV) from the herpes zoster patient to the HCW and further from the HCW to our patient. Assessing the immunity of HCWs to varicella at the time of employment, ensuring only HCWs with immunity take care of herpes zoster and varicella patients, furloughing unimmunized exposed HCWs, offering PEP, and documentation of patients' immunity to varicella at the time of hospital admission could help prevent VZV transmission in hospital settings. This is an attempt to publish this novel case due to its high educational value and relevant learning points.

Subacute Thyroiditis Masking as Fever of Unknown Origin: An Intriguing Case Report.

This study presents a unique case of subacute thyroiditis, which presents as prolonged high-grade fever without any other symptoms except for mild throat pain. A 46-year-old, otherwise healthy male presented with high-grade fever for more than two to three weeks and was found to have hyperthyroidism, with elevated free thyroxine levels (free T4), low thyroid-stimulating hormone (TSH) levels, elevated c-reactive protein (CRP) an inflammatory marker, and heterogeneous bilateral thyroid nodules on imaging studies. His workup was negative for infectious etiology of fever, thus favoring the diagnosis of subacute thyroiditis as the cause of fever of unknown origin (FUO). This case highlights the importance of considering subacute thyroiditis as a potential etiology in patients with FUO and the significance of a comprehensive workup to guide appropriate management.

The Uncharted Link Between Desogestrel and Hypercalcemia.

This report presents a unique case of hypercalcemia with an elusive etiology. A 37-year-old Caucasian female with a history of gonadotropin-secreting pituitary microadenoma and recurrent nephrolithiasis was found to have hypercalcemia, hypercalciuria, elevated 1,25-dihydroxyvitamin D levels, and low parathyroid hormone levels. Extensive investigations were conducted to identify the cause, including ruling out sarcoidosis and other granulomatous disorders. Imaging and diagnostic testing revealed normal results. The patient's condition considerably improved after the cessation of an oral contraceptive pill containing desogestrel. This surprising association raises the possibility that the use of desogestrel could result in hypercalcemia as one of the side effects. To ensure proper care and avoid consequences linked to severe hypercalcemia, a high index of suspicion is needed to detect the underlying cause of hypercalcemia, even in the absence of usual indications.
