Cat scratch disease is an infection which often causes regional lymphadenopathy. Bartenolloses present a growing health problem both in human and veterinary medicine. They may be etiological fevers of unknown etiology, endocarditis, pneumonia, meningitis. The mildest clinical form is the cat scratch disease which proceeds as a mild regional lymphadenopathy. It is caused by Bartonellosis henselae. Animals, especially cats, are the sourse of infections. Lymphadenitis may remain for many weeks and requires differentiation from other causes of regional lymphadenopathy. Three typical cases of the disease are presented. All sick persons had contact with cats. In none case a primary change was observed. In the case no 1 the possibility of occurrence of the disease was not considered and it was diagnosed only after histopathological examination of lymphnodes. In the two other cases diagnoses were established on the basis of serological examination after a few days of admittance for hospital treatment. Cat scratch disease is rarely diagnosed in Poland probably due to insufficient knowledge of the clinical form of this disease. Swollen lymph nodes together with patient contact with a cat or other animals established during a detailed interviewing, raise suspicion of CSD. Denial by a patient of the primary change does not rule out diagnosis. When regional lymphadenopathy of cat scratch disease is taken into consideration in differential diagnosis and serological tests are carried out, it may be possible in many cases to eliminate any further diagnostics burdening a sick person.

Pneumonia with septicemia caused by Pasteurella multocida was diagnosed in an immunocompetent patient exposed to a dog. This case is remarkable by two aspects: first the absence of visible cutaneous lesion, and second the localization and severity of the infection caused by P. multocida even though the patient was immunocompetent. P. multocida can cause respiratory and systemic infection, and it is a possible diagnosis in case of exposure to animals, even without history of bite or scratch. Furthermore, severe infections caused by this pathogen can occur in immunocompetent patients, so that the implication of specific host factors in the severity of the disease can be suspected. Genetic features could be one of these.

Pasteurella multocida infections in humans can present as localized infections of soft tissues surrounding the lesions, as respiratory tract infections or as systemic infections with slow or fulminant development. Over 90% of human infections are cases of wound infections or abscesses related to a bite, scratch, or licking of skin lesions by a cat or dog. Severe systemic diseases such as pneumonia, lung abscess, peritonitis, endocarditis, meningitis and sepsis are also well known, especially in patients with underlying medical conditions. In this paper we report on an immunocompromised patient who was bitten by an unknown cat and very quickly developed fulminant sepsis, dying 70 hours after the cat bite, despite all the intensive care, therapy and reanimation he was given. Unfortunately, he asked for medical help too late. We emphasize the need for primary healthcare to provide more information to patients at risk of infections from contact with animals and to warn them about the possible consequences of injuries, even when the animals are pets.

We report a case of rapidly progressive pneumonia and meningoencephalitis in a 2-month-old breastfed infant. Culture of cerebrospinal fluid was positive for Pasteurella multocida. No bite or scratch injury as site of entrance could be detected clinically or at autopsy, therefore aerogenic transmission in droplets from a household pet must be considered. Infections with P. multocida have been frequently reported in infants and elderly people; however, rapidly progressive and lethal infections in infants have been described only rarely. These infections must be regarded as preventable through adequate measures of hygiene.

Kikuchi-Fujimoto disease, also known as histiocytic necrotizing lymphadenitis of unknown etiopathogenesis, is a self-limited disease which frequently appears as feverish lymphadenomegaly, thus creating the need for differential diagnosis with lymphoma, systemic lupus erythematosus (SLE), infectious mononucleosis, cat-scratch disease, and toxoplasmosis with lymphonodal impairment. However, there are cases in which it may evolve with complications such as aseptic meningitis, cerebellar ataxia, and aseptic myocarditis. We are presenting a case of a 24-year-old man who had an initial picture of arthralgia, evening fever and adenomegaly. Kikuchi disease was diagnosed through lymph node biopsy with immunohistochemistry and evolves with severe systemic manifestations, such as pericarditis with cardiac tamponade, pneumonitis, hepatitis, and acute kidney failure - the latter has not been reported in literature yet. There was significant improvement of the clinical picture with prednisone.

Pasteurella multocida is a Gram-negative coccobacillus that colonises the upper airways of many animals, in particular, dogs and cats. It acts as an opportunistic infection in humans following an animal bite or scratch and is associated with soft tissue infections, septicaemia and pneumonia, particularly in patients with a compromised immune response, such as patients with liver failure. Spontaneous bacterial peritonitis (SBP) is a serious complication of cirrhosis with a death rate of 10-15%. We report a case of a 47-year-old man with cirrhosis who presented with life-threatening P multocida SBP and bacteraemia secondary to a lick from a cat to a cellulitic leg wound. This case highlights the potential severity of an infection from domestic animals and an otherwise innocuous organism in an immunocompromised host.

Streptococcus pneumoniae (pneumococcus) is mostly known as an agent of meningitis and pneumonia. We present what is believed to be a previously unreported case of pneumococcal disease, involving an inguinal wound. A 10-year-old male patient underwent surgical removal of a cat-scratch disease-related enlarged groin lymph node; infection of the wound was soon observed, with multidrug-resistant S pneumoniae growing from the lesion discharge. This communication expands the spectrum of skin ulcer-infecting pathogens; in fact, although pneumococcus has been known to mostly affect central nervous system and airways, we observed a surgical wound infection by this organism.

Pasteurella is one of the zoonotic pathogens that can cause variety of serious infections in animals and humans such as bacteremia, septic shock, endocarditis, meningitis, prosthetic and native valve infections, osteomyelitis, skin and soft tissue infections, abscesses, and even pneumonia with empyema. However, there have been few reports of upper respiratory involvements like tonsillitis and epiglottitis in humans. We present a case of recurrent Pasteurella glossitis after a cat scratch which has not been reported in humans.

Hypercalcaemia occurs in many granulomatous diseases. Among them, sarcoidosis and tuberculosis are the most common causes. Other causes include berylliosis, coccidioidomycosis, histoplasmosis, Crohn's disease, silicone-induced granulomas, cat-scratch disease, Wegener's granulomatosis and Pneumocystis carinii pneumonia. Hypercalcaemia in granulomatous disease occurs as a consequence of dysregulated production of 1,25-(OH)2 D3 (calcitriol) by activated macrophages in granulomas. Hypercalcaemia in patients with Mycobacterium tuberculosis infection has been reported in 0%-28% of cases. Uncultured bronchoalveolar lavage cells from patients with M. tuberculosis produce greater amounts of calcitriol compared with controls. Although Nayar et al described hypercalcaemia in a case of sepsis associated with intravesical Bacille Calmette Guerin therapy, there are no published reports describing hypercalcaemia in patients with pulmonary M. bovis infection. We describe a patient with M. bovis cavitary pulmonary infection with sustained hypercalcaemia that fluctuated and recurred repeatedly over the course of therapy, ultimately culminating in normalisation of serum calcium when therapy had led to cure. Treatment consisted of antituberculous therapy, oral corticosteroids and intravenous bisphosphonates with a favourable outcome.

A 64-year-old man was prescribed maoto, a prevailing Chinese herbal, for a cold with upper respiratory inflammation. Two days later, he developed a high fever, progressive dyspnea and pulmonary infiltration on chest high-resolution computed tomography (HRCT) including diffuse ground-glass opacity mainly around bronchovascular bundles and partial distribution of subpleural cysts resembling honeycombing. Despite the administration of azithromycin and pazufloxacin, the pulmonary infiltration and hypoxemia has rapidly progressed, so he was referred to our hospital. Although fulminant pneumonia or the acute exacerbation of idiopathic pulmonary fibrosis (IPF) was considered, his respiratory symptoms and pulmonary infiltration immediately improved and oxygen therapy was not needed on the fifth hospital day. Based on the clinical course, laboratory findings and the chest imaging findings, drug induced interstitial lung disease was suspected. The drug-induced lymphocyte test (DLST) as well as a scratch test against maoto demonstrated positive results. This is the first case report of maoto-induced interstitial pneumonia that was diagnosed based on the patient's clinical course, chest imaging findings and laboratory findings.
