Pseudomonas luteola which was previously known as Chryseomonas luteola; is a gram-negative, non-fermentative, aerobic, motile, non-spore-forming bacillus. It is frequently found as a saprophyte in soil, water and other damp environments and is an opportunistic pathogen in patients with underlying medical disorders or with indwelling catheters. It has been reported as an uncommon cause of bacteremia, sepsis, septic arthritis, meningitis, endocarditis, and peritonitis. Thus, early and accurate identification of this rare species is important for the treatment and also to provide information about the epidemiology of P.luteola infections. This report was aimed to draw attention to the accurate identification of P.luteola in clinical samples, upon the isolation and identification in two cases in the medical microbiology laboratory of a university hospital. In February 2011, a 66-year-old man, with chronic obstructive pulmonary disease, coronary artery disease and aplastic anemia, was admitted to our hospital due to progressive dyspnea. A chest tube was inserted on the 20th day of admission by the reason of recurrent pleural effusion. Staphylococcus aureus and a non-fermentative gram-negative bacillus (NFGNB) with wrinkled, sticky yellow colonies were isolated from the pleural fluid sample obtained on the 9th day following the insertion of the chest tube. In February 2012, a 7-year-old male cystic fibrosis patient who had no signs and symptoms of acute pulmonary exacerbation was admitted to the hospital for a routine control. This patient had chronic colonization with Pseudomonas aeruginosa and S.aureus and his sputum sample obtained at this visit revealed isolation of P.aeruginosa, S.aureus, Aspergillus fumigatus and a wrinkled, sticky yellow NFGNB. Both of these NFGNB were identified as P.luteola by the Phoenix automated microbial identification system (BD Diagnostics, USA). To evaluate the microbiological characteristics of these two isolates, the strains were further analysed by VITEK MS (bioMerieux, France) and Microflex LT mass spectrometer (Bruker Daltonics, Germany). Both of the MALDI-TOF-MS systems identified the isolates as P.luteola and 16S rRNA gene sequencing (ABI PRISM 3100, Applied Biosystems, USA) also confirmed the identification. The strains had wrinkled, sticky yellow colonies which were oxidase-negative, catalase-positive and non-fermentative. The Gram stained smears of the colonies revealed clusters of gram-negative bacilli probably embedded into a biofilm matrix. Since there are no accepted standards for testing the antibiotic susceptibility of P.luteola strains, the standards determined by CLSI for "other non-Enterobacteriaceae" (non-fermentative bacteria excluding P.aeruginosa, Acinetobacter spp., Burkholderia cepacia, B.mallei, B.pseudomallei and Stenotrophomonas maltophilia) were used for the susceptibility testing. Gradient MIC method (E-Test, bioMerieux, France) revealed that the isolates were susceptible to gentamicin, piperacillin-tazobactam, ceftazidime, cefepime, meropenem, colistin and levofloxacin. Accurate and prompt identification of P.luteola which is identified as a rare pathogen in serious cases is of critical importance since it has been suggested that this organism is likely to become more frequent as a nosocomial pathogen since the interventional processes increase in current medical practice. This report supported that Phoenix automated phenotypic identification system (BD Diagnostics, USA) and the two MALDI-TOF-MS based systems (VITEK MS and Bruker Microflex LT mass spectrometer) were successfull in the accurate identification of P.luteola.

Tuberculous peritonitis in pregnancy is a rare form of extrapulmonary tuberculosis that is not easily diagnosed. The clinical presentations of tuberculous peritonitis are usually non-specific and mimic those of other diseases, such as ovarian malignancy or chronic liver disease, and this non-specificity can cause diagnostic delays and complications. The authors report the case of a 31-year-old primigravida woman who presented with uncontrolled fever, dyspnea, elevated liver enzymes, and mild abdominal distension at 13+2 weeks of gestation. At 14+2 weeks, a therapeutic abortion was conducted and tuberculous peritonitis was confirmed by laparoscopic excisional biopsy of peritoneal nodules and histopathologic examination. The patient recovered on antituberculosis therapy and abdomen and chest follow up radiographic findings have confirmed improvement.

Intraperitoneal free air (IFA) is sometimes accompanied by pneumatosis cystoides intestinalis (PCI); therefore, proper diagnosis is essential for PCI management. We report two cases of PCI with IFA. A 70-year-old female taking anti-psychotic medication for schizophrenia presented with repeated vomiting and high-grade fever. Computed tomography revealed small, linear gaseous cysts in the intestinal wall along with IFA. Although there was no sign of peritoneal irritation, intestinal perforation was not excluded. Thus, exploratory laparotomy was performed; it revealed no ascites or perforated sites in the intestine, and revealed numerous small air bubbles in the intestinal wall and mesentery. Thus, a diagnosis of PCI was made, and ileostomy was performed to relieve intestinal pressure. The postoperative course was uneventful. A 79-year-old male with pulmonary emphysema presented with dyspnea due to abdominal distention. Cyanosis was evident, and arterial blood gas analysis revealed metabolic acidosis. CT revealed massive IFA along with multiple, small bubbly cysts under the intestinal serosa. He was intubated because of worsening respiratory conditions, and a 12-French drain was inserted to relieve the intraperitoneal pressure. There was no evidence of peritonitis, and IFA was conservatively observed.

Lymphoproliferative disorder (LPD) is a potentially severe adverse effect of methotrexate (MTX) administration in patients with rheumatoid arthritis (RA). We report a case of MTX-associated LPD (MTX-LPD) in a patient with RA who developed severe pulmonary failure complicated by perforation of the terminal ileum. A 61-year-old woman with RA receiving MTX complained of dyspnea and abdominal pain. She was diagnosed with intestinal perforation and peritonitis, and underwent immediate abdominal surgery. Pathological examinations of the specimen obtained from the resected ileum and a bone marrow aspirate revealed diffuse large B-cell lymphoma. Steroid therapy failed to improve her respiratory failure, but her condition improved after abdominal surgery and suspension of MTX. MTX-LPD can result in multiple life-threatening conditions; however, the symptoms are highly variable. RA patients receiving MTX should thus be monitored carefully, and MTX administration should be stopped immediately on suspicion of MTX-LPD.

Colonoscopic perforation is a serious and potentially life-threatening complication of colonoscopy. Its incidence varies in frequency from 0.016% to 0.21% for diagnostic procedures, but may be seen in up to 5% of therapeutic colonoscopies. In case of extraperitoneal perforation, atypical signs and symptoms may develop. The aim of this report is to raise the awareness on the likelihood of rare clinical features of colonoscopic perforation. A 72-year-old male patient with a past medical history of myocardial infarction presented to the emergency department four hours after a screening colonoscopy with polypectomy, complaining of neck pain, retrosternal oppressive chest pain, dyspnea, and rhinolalia. Right chest wall and cervical subcutaneous emphysema, pneumomediastinum, pneumoretroperitoneum, and bilateral subdiaphragmatic free air were reported on the chest and abdominal X-rays. The patient was treated conservatively, with absolute bowel rest, total parental nutrition, and broad-spectrum intravenous antibiotics. Awareness of the potentially unusual clinical manifestations of retroperitoneal perforation following colonoscopy is crucial for the correct diagnosis and prompt management of colonoscopic perforation. Conservative treatment may be appropriate in patients with a properly prepared bowel, hemodynamic stability, and no evidence of peritonitis. Surgical treatment should be considered when abdominal or chest pain worsens, and when a systemic inflammatory response arises during the conservative treatment period.

Aeromonas peritonitis is a rare, but serious infection, as associated with spontaneous bacterial peritonitis, peritonitis in chronic ambulatory peritoneal dialysis, and intestinal perforation. Here, we reported a case of monomicrobial non-neutrocytic bacterascites caused by Aeromonas hydrophila (A. hydrophila). The patient, a 57-year-old man who had a history of alcoholic liver disease and chronic hepatitis C-related Child- Pugh class C liver cirrhosis, was admitted to our hospital with fever, dyspnea and a localized wound pain over left ankle. Ascitic fluid analysis demonstrated that ascitic polymorphonuclear cell count was 30 cells/ mm3. Empirical antimicrobial treatment with a combination of ceftriaxone and clindamycin were administered. However, the patient died due to fatal septic shock on Day 3. His blood and ascites cultures were positive for A. hydrophila. The case report presents the diagnosis, management, and literature review of Aeromonas monomicrobial non-neutrocytic bacterascites.

Extra-nasal types of Extra-nodal natural killer cell lymphoma (ENKL) have been known with poorer prognoses than nasal type with the worst responses to treatment. The current work introduces a case of ENKL with GI involvement with no nasal manifestations. We report a 56-year male farmer with fever, productive cough, dyspnea, anorexia, vomiting and chill in addition to malaise and cachexia of three months duration referred to a hospital with acute abdominal pain, and was diagnosed as peritonitis due to perforated terminal ileum ulcer before experiencing surgery as a case of acute abdomen. The pathologic study of the relevant biopsy showed "ulceration and necrosis with dense fibrinoleukocytic exudation and granulation tissue formation. CT scan determined a bilateral mass like haziness which was more likely to be metastatic. The review of the previous pathologic specimens raised Natural Killer/T cell Lymphoma (NKTL), the reason for which we focused on the patient's sinuses and nasal area as well as nasopharynx. There was no finding in examination and endoscopy of sinuses. Pathology also found malignant high grade non-Hodgkin T cell lymphoma in specimens obtained from debridement of ulcer at terminal ileum. It also showed that most of the tumor cells were positive for CD3, CD56, CD8, and LCA but negative for CD19, CD20 and AE1/AE3. Positive reactions for CD30 were shown by some cells. CD56, CD3, and CD8 were expressed by neoplastic cells and CD30 were positive in few cells. Proliferative activity (Ki67 index) was high (60-70%). This was the main base to diagnose an extra-nodal extra-nasal NK/T cell lymphoma. In conclusion, Intestinal changes at middle age, especially in men with nonspecific clinical manifestations is highly advised to be studied pathologically and genetically for T cell types like CD30 positive T cells which are usually engaged in ENKTL.
