Three pediatric and two adult Turkish patients with Crimean Congo Hemorrhagic Fever (CCHF) induced hemophagocytic syndrome (HPS) were admitted to Ondokuz Mayis University Hospital, which is in the Middle Black Sea Region of Turkey. All of them had remarkable hemophagocytosis in the bone marrow with severe bleeding symptoms along with the other known clinical and laboratory findings of CCHF. We would like to present these patients and to discuss the pathophysiology and the effect of acquired HPS on the severity of the disease. Am. J. Hematol., 2008. © 2007 Wiley‐Liss, Inc.
Purpose The objective of this study is to evaluate smell and taste dysfunction (STD) in coronavirus disease 2019 positive and negative patients, and to assess the factors associated with STD in COVID-19 positive patients. Methods Patients who had been tested with the real-time reverse transcriptase-polymerase chain reaction (RT-PCR) for COVID-19 were identified, and according to the RT-PCR test results, patients were separated into Positive and Negative Groups. A telephone-based assessment was applied to both groups using the American Academy of Otolaryngology-Head and Neck Surgery Anosmia Reporting Tool. Patients in Positive Group were also asked to rate STD, nasal breathing, and anxiety in three different time periods (pre-/during-/post-COVID) using the visual analog scale (VAS). Results A total of 53 COVID-19 positive and 51 negative patients completed the surveys. STD was eightfold more frequent (OR 8.19; CI 95% 3.22-20.84) in the Positive Group. Of the 53 COVID-19 positive patients, 32 reported STD and 21 did not. 'Ground-glass appearance' on chest-computed tomography was more frequent and median lymphocyte count was significantly lower in COVID-19 positive patients with STD. During-COVID STD and nasal breathing VAS scores were significantly lower than the pre-and post-COVID scores. During-COVID STD scores were significantly correlated with anxiety scores (Spearman's rho-0.404, p = 0.022) but not correlated with nasal breathing scores. Conclusion STD may be related to increased inflammatory response as well as damage of olfactory neuronal pathway or non-neuronal olfactory mucosa. Understanding the exact cause of chemosensory impairment in COVID-19 can be helpful in explaining the pathophysiology of the disease.
Treatment of multidrug resistant (MDR) Acinetobacter baumannii infections causes some problems as a result of possessing various antibacterial resistance mechanisms against available antibiotics. Combination of antibiotics, acting by different mechanisms, is used for the treatment of MDR bacterial infections. It is an important factor to determine synergy or antagonism between agents in the combination for the constitution of effective therapy. The study aimed to determine In vitro interactions interpreted according to calculated fractional inhibitory concentration (FIC) index between sulbactam and ceftazidime, ceftriaxone, cefepime, ciprofloxacin, gentamicin, meropenem, tigecycline, and colistin. Ten clinical isolates of A. baumannii were tested for determination of synergistic effects of sulbactam with different antimicrobial combinations. Minimal inhibitory concentration (MIC) values of both sulbactam and combined antibiotics decreased 2- to 128-fold. Synergy and partial synergy were determined in combination of sulbactam with ceftazidime and gentamicin (FIC index: ≤ 0.5 or >0.5 to <1) and MIC values of both ceftazidime and gentamicin for five isolates fell down below the susceptibility break point. Similarly, MIC value of ciprofloxacin for six ciprofloxacin resistant isolates was determined as below the susceptibility break point in combination. However, all isolates were susceptible to colistin and tigecycline, MIC values of both were decreased in combination with sulbactam. Although synergistic and partial synergistic effects were observed in the combination of sulbactam and ceftriaxone, all isolates remained resistant to ceftriaxone. The effect of cefepime-sulbactam combination was synergy in five, partial synergy in one and indifferent in four isolates. Meropenem and sulbactam showed a partial synergistic effect (FIC index: >0.5 to <1) in three, an additive effect (FIC index: 1) in one and an indifferent effect (FIC index: >1-2) in six isolates. Antagonism was not determined in any combination for clinical A. baumannii isolates in the study. In conclusion, sulbactam is a good candidate for combination treatment regimes for MDR A. baumannii infections.
Babesiosis is a zoonotic disease that may be asymptomatic or result in severe clinical conditions, with severe hemolysis, hepatic, and renal failure, in humans. Clinical symptoms depend on the species and immune status of the host. The disease is especially severe in those of advanced age, those with an immune deficiency, and the splenectomized. A severe case of babesiosis that developed in a splenectomy patient is presented here; the patient was admitted from a rural region with severe anemia and a deterioration in her general condition, with an initial diagnosis of malaria. In such situations, an exchange transfusion (ET), in addition to antimicrobial treatment, could be lifesaving.
A case of infective endocarditis caused by an uncommon agent with atypical manifestations is presented. A 42-year-old woman previously had rheumatic heart disease, presented with the symptoms of fever and chills that resolved within 3 days under antibiotherapy. She was diagnosed with endocarditis due to. Despite culture-directed antibiotics being administered in the first admission, her symptoms and also blood culture growth relapsed 3 weeks later. She was successfully treated with antimicrobial therapy and surgical intervention including aorta and mitral valve replacement. This case demonstrates that should be considered as a causative organism of endocarditis particularly in the presence of atypical symptoms and should be followed up carefully in terms of relapses and complications.
NT was found to be a prognostic factor in patients with sepsis.
Here, we describe a 38-year-old male with an abrupt manifestation acute panniculitis as unusual presentation of brucellosis. Brucellosis is a reemerging disease in Turkey, and the disease is primarily transmitted from farm animals to humans. Farmers and shepherds are the major risk groups for brucellosis in Anatolia. Brucellosis may involve almost all systems and organs, including the skin, and may mimic a wide range of illness and syndromes. Although the cutaneous manifestation of brucellosis is not disease specific, but it occurs in about 6%-13% of patients with brucellosis. Some of these lesions including rashes, papules, ulcers, abscess, erythema nodosum, ecchymosed skin rash, purpura, and vasculitis may be seen frequently in brucellosis, but panniculitis is rarely described. The case confirmed by positive blood culture had manifest skin lesion as an initial finding represented by lobular panniculitis with vasculitis.
