Acquired factor X deficiency in a multiple myeloma without amyloidosis: a case report.

BACKGROUND: Multiple myeloma is one of the most common hematologic malignancies. Acquired factor X deficiencies are often observed in primary (AL) amyloidosis and rarely in multiple myeloma. OBJECTIVE: We report a case of an acquired factor X deficiency in a patient with a newly diagnosed IgA lambda multiple myeloma, without any evidence of concomitant amyloidosis. METHODS: We present the patient's medical history, clinical and physical examinations, laboratory analysis, and outcome. RESULTS: A 76-year-old male presented at the emergency department with ongoing gingival bleeding. Several analytical problems with blood sample analysis arose, which eventually led to the diagnosis of a multiple myeloma. Further exploration revealed an acquired factor X deficiency, explaining the ongoing bleeding. There was no evidence of concomitant amyloidosis. The multiple myeloma was treated, leading to complete remission of the malignancy and bleeding tendency. CONCLUSION: While coagulopathy is rarely observed in patients diagnosed with multiple myeloma, considering an acquired factor X deficiency becomes relevant when such patient present with bleeding diathesis.

Thyroid gland involvement in secondary syphilis: a case report.

BACKGROUND: Syphilis is a systemic, infectious disease caused by Treponema pallidum and is notorious for the variety of its clinical presentations. OBJECTIVE: We report a case of secondary syphilis with thyroid gland and ocular involvement in a human immunodeficiency virus (HIV) negative patient. METHODS: We present the patient's history, clinical findings, laboratory test results, imaging and management. RESULTS: A 39-year-old Caucasian, HIV unaffected woman presented with acute midline neck swelling, dyspnea and difficulty to talk or swallow. Serologic tests for syphilis were positive. PCR performed on a thyroid fine needle aspiration cytology (FNAC) aspirate was positive for Treponema pallidum. Skin lesions and unilateral loss of vision were present. Treatment with intravenous benzyl-penicillin showed a good regression of symptoms. CONCLUSION: We report an unusual case of thyroid swelling in a secondary syphilis infection. Awareness of syphilis as a differential diagnosis is important in a risk population.

Antimicrobial resistance of Helicobacter pylori in West Flanders - Belgium: an observational cross-sectional study.

OBJECTIVES: Data on Helicobacter pylori (HP) resistance in Belgium are largely based on the patient population of Brussels and Wallonia. Notably Brussels harbours a large proportion of patients with a migration background which might not be representative for other parts of the country. METHODS: An observational cross-sectional study was performed in the province of West Flanders, Belgium for collecting gastric biopsies to examine the resistance of HP. The study population consisted of patients who underwent a gastroduodenoscopy for any medically indicated purpose. Rapid urease testing (RUT) was performed on all biopsies and cultures were only started if the RUT showed positive. RESULTS: 512 patients participated of whom 495 were eligible for analysis: 438 in first line testing and 57 in second line. The growth of HP was successful in 88.9% (n = 88/99) of which 52.3% (n = 46/88) resulted in an antibiogram. The resistance rate in first line was based on 37 succeeded antibiograms and showed 13.5% resistance for clarithromycin (95% confidence interval; 2.5% to 24.5%); 29.7% for metronidazole; 29.7% for levofloxacin; 11.4% for rifampicin; 2.7% for amoxicillin and 0% for tetracycline. CONCLUSION: The primary clarithromycin resistance rate of HP could still be slightly under 15% in West Flanders, Belgium. This might implicate a clarithromycin-based triple therapy is an option for first line empiric eradication in this region according to the Maastricht V/Florence consensus although conclusions must be interpreted with caution due to the rather small sample size. Further testing in Flanders is recommended to confirm these results.

Lemierre's syndrome: a case study with a short review of literature.

OBJECTIVE AND IMPORTANCE: Lemierre's syndrome (LS) is a rare condition that typically starts with a bacterial oropharyngeal infection complicated by a thrombophlebitis of the internal jugular vein and septic emboli to the lungs or other organs. The most common organism isolated is Fusobacterium necrophorum, although other causative organisms are isolated in rare cases. CASE PRESENTATION: We discuss a case of LS in a 44-year-old, previously healthy man presenting with an oropharyngeal infection. F. necrophorum was isolated from blood cultures and Computed tomography of the chest demonstrated septic emboli in the lungs. Magnetic resonance imaging showed a thrombophlebitis of the sigmoid and transverse vein with continuity to the internal jugular vein. METHODS: Case report and literature review. RESULTS: F. necrophorum isolates show in vitro susceptibility to metronidazole, clindamycin, beta-lactam/beta-lactamase inhibitor combinations and carbapenems with no signs of resistance or reduced sensitivity. Anticoagulation is believed to play a favourable role in recovery of the disease because of the potential for faster resolution of thrombophlebitis and bacteraemia. Conflicting results exist in literature with many studies or reviews indicating a favourable outcome both with and without anticoagulation. Anticoagulation for LS consists in most cases of Warfarin or Low molecular weight heparins, with the last being the first choice in children. Indications for the use of anticoagulation in literature are significant clot burden, complication of septic emboli, arterial ischemic stroke, poor response to antibiotics, thrombophilia and cerebral infarction. CONCLUSIONS: Antibiotics are considered the mainstay of treatment, although statistically valid trials to evaluate optimal treatment regimens have not yet been conducted due to the low incidence of the infection. The use of anticoagulation in LS is still heavily debated as a result of conflicting results in literature. Due to the disease's low incidence, statistically valid trials that evaluate anticoagulation are lacking. Further prospective and randomized research is needed to establish the benefit of anticoagulation in the treatment of LS.

Ascaris lumbricoides: challenges in diagnosis, treatment and prevention strategies in a European refugee camp.

OBJECTIVES:  The roundworm Ascaris lumbricoides is one of the most prevalent parasites belonging to the class of the soil-transmitted helminths. Infections are most common in developing countries with a tropical climate where sanitation and hygiene are poor. However, prevalence of ascariasis in industrialized countries is increasing because of immigration and increasing number of refugees. METHODS:  We report a case of ascariasis in a female patient who was admitted to our hospital after she had left the informal refugee camp of Calais in the north of France. RESULTS:  After colonoscopic removal of the worm and treatment with mebendazole during three days the patient's symptoms had completely resolved. Medical treatment with benzimidazole derivatives is easy and inexpensive. To prevent parasitic infections in larger populations, mass drug administration should be repeated periodically and must be implemented along with additional measures such as improvements to water, sanitation and hygiene (WASH). These WASH programs have been proven to be highly effective, but access and follow-up are expensive and very difficult to organize in refugee camps, even in wealthy, industrialized countries. CONCLUSIONS: Despite being an old, well-known parasitic disease, ascariasis might reappear in certain populations at risk in industrialized countries. Detection, treatment and follow-up of these patients, and the organization of preventive measures remain challenging.
