Vemurafenib-induced toxic epidermal necrolysis: possible cross-reactivity with other sulfonamide compounds.

Vemurafenib is a newly licensed target-directed medication. It has been proven to improve the survival of patients with metastatic melanoma and the BRAF(V600E) mutation; however, adverse cutaneous reactions are frequent. Few cases of life-threatening severe cutaneous adverse reactions (SCARs) induced by vemurafenib have been reported. Dabrafenib, another selective BRAF inhibitor, has been licensed recently as an alternative drug with the same indications. From a molecular point of view, both vemurafenib and dabrafenib contain a sulfonamide group; cross-reactivity to sulfonamide compounds has been reported in allergic patients. We report on a patient with vemurafenib-induced toxic epidermal necrolysis (TEN). In vitro analysis of lymphocyte reactivity to vemurafenib showed positive results, confirming drug causality. In addition, lymphocytes from the patient reacted to dabrafenib and to the antibiotic sulfonamide drug sulfamethoxazole. Moreover, lymphocytes from two patients with cutaneous adverse reactions to sulfamethoxazole also reacted to vemurafenib and dabrafenib in vitro. These data strongly suggest that there might be clinical cross-reactivity between BRAF inhibitors and sulfonamides in some patients. Thus, precautions should be taken to avoid sulfonamide drugs as much as possible in patients showing serious hypersensitivity reactions to vemurafenib and vice versa.

Drug Levels and Antibodies Against TNF-blockers in Spondyloarthritis and Rheumatoid Arthritis are Associated with the Activity but they do Not Predict it.

BACKGROUND: Many patients may have resistance to TNF-blockers. These drugs may induce neutralizing antibodies. The determination of the drug levels of TNF-blockers and Anti-Drug Antibodies (ADAs) against TNF-blockers may help to make clinical decisions. OBJECTIVES: The objective of this study was to associate and predict the drug levels of TNFblockers and ADAs in relation to disease activity in patients with Spondyloarthritis (SpA) and Rheumatoid Arthritis (RA). METHODS: Cross-sectional study including patients fulfilling ASAS classification criteria for SpA and 2010 ACR-EULAR classification criteria for RA. These patients were treated with Adalimumab (ADA), Infliximab (IFX), and Etanercept (ETN). A bivariate analysis and the chi-square test were performed to evaluate the association of ADAs and drug levels with activity measures for SpA and RA. Five regression models analyzing drug levels, ADAs and disease activity measures using a multiple linear regression were performed in order to evaluate the prediction of ADAs and drug levels in relation to disease activity. RESULTS: In SpA, IFX levels were associated with BASDAI (Bath Ankylosing Spondylitis Disease Activity Index) (p=0.034). In RA, total drug levels were associated with DAS28-ESR (28 joint Disease activity Score-erythrocyte sedimentation rate), (p=0.008), DAS28-CRP (p=0.042), CDAI (Clinical Disease Activity Index) (p=0.047) and SDAI (Simple Disease activity index), (p=0.017). ADA levels had association with CDAI (p=0.002) and SDAI (p=0.002). IFX levels were associated with a DAS28-ESR (p=0.044), DAS28-CRP (p=0.022) and SDAI (p=0.022). ADAs were associated in SpA with BASDAI (p=0.027). Drug levels and ADAs did not predict disease activity in patients with SpA or RA. CONCLUSION: ADAs and drug levels of anti-TNF are associated with disease activity measures in patients with SpA and RA. However, they cannot predict clinical activity in these conditions.

Activity of caspofungin and voriconazole against clinical isolates of Candida and other medically important yeasts by the CLSI M-44A disk diffusion method with Neo-Sensitabs tablets.

In vitro activity of caspofungin and voriconazole against 184 clinical isolates of Candida and other medically important yeasts in comparison with that of fluconazole, ketoconazole, itraconazole and amphotericin B was determined by using a disk diffusion method (Neo-Sensitabs) standardized according to the recommendations of the CLSI documents M44-A and M44-S1 (same medium: Mueller-Hinton plus methylene blue; inoculum and minimal inhibitory concentration/zone breakpoints). Seventy-two percent of clinical isolates were susceptible to caspofungin, 23.6% showed an intermediate susceptibility (most of them were Candida parapsilosis) and 4.3% were resistant (values for Candida spp. were 71.2, 23.8 and 5%, respectively). For voriconazole, 96.7% of clinical isolates were susceptible and 3.3% were resistant (Candida spp.: 96 and 3.8%, respectively). Both caspofungin and voriconazole showed high activity against a wide variety of clinically important yeasts.

In vitro activity of voriconazole against dermatophytes, Scopulariopsis brevicaulis and other opportunistic fungi as agents of onychomycosis.

Using a reference microdilution method, we studied the antifungal susceptibility to voriconazole and fluconazole of 304 clinical isolates from four species of onychomycosis-causing dermatophytes, 196 isolates of dermatophytes not related to nail infection as well as Scopulariopsis brevicaulis, Fusarium spp. and Scytalidium dimidiatum. Results showed a high antifungal activity of voriconazole against dermatophytes (geometric mean minimal inhibitory concentration (MIC)=1.14 microg/mL; MIC for 50% of the organisms (MIC(50))=0.062 miccrog/mL; MIC for 90% of the organisms (MIC(90))=0.25 microg/mL). For S. brevicaulis, the in vitro activity of voriconazole was considerably lower (geometric mean MIC=8.52 microg/mL; MIC(50) and MIC(90)=16 microg/mL). Although voriconazole is not among the drugs recommended for the management of onychomycosis, it can be a useful alternative for recalcitrant infections.

Area contact networks and the spatio-temporal spread of infectious salmon anemia virus (ISAV) in Chile.

Area management, the coordination of production and biosecurity practices across neighboring farms, is an important disease control strategy in aquaculture. Area management in aquaculture escalated in prominence in response to outbreaks of infectious salmon anemia (ISA) internationally. Successes in disease control have been attributed to the separation achieved through area-level synchronized stocking, fallowing, movement restrictions, and fomite or pest control. Area management, however, is costly; often demanding extra biosecurity, lengthy or inconveniently timed fallows, and localization of equipment, personnel, and services. Yet, this higher-order organizational structure has received limited epidemiologic attention. Chile's National Fisheries and Aquaculture Service instigated area management practices in response to the 2007 emergence of ISA virus (ISAV). Longitudinal data simultaneously collected allowed retrospective evaluation of the impact of component tenets on virus control. Spatiotemporal analyses identified hydrographic linkages, shared ports, and fish transfers from areas with recent occurrence of ISAV as the strongest predictors of virus spread between areas, though specifics varied by ISAV type (here categorized as HPR0 for the non-virulent genotypes, and HPRv otherwise). Hydrographic linkages were most predictive in the period before implementation of enhanced biosecurity and fallowing regulations, suggesting that viral load can impact spread dynamics. HPR0 arose late in the study period, so few HPRv events were available by which to explore the hypothesis of HPR0 as progenitor of outbreaks. However, spatiotemporal patterns in HPRv occurrence were predictive of subsequent patterns in HPR0 detection, suggesting a parallel, or dependent, means of spread. Better data precision, breadth and consistency, common challenges for retrospective studies, could improve model fit; and, for HPR0, specification of diagnostic test accuracy would improve interpretation.

Role of immunosuppression in the development of quinolone-resistant Escherichia coli spontaneous bacterial peritonitis and in the mortality of E. coli spontaneous bacterial peritonitis.

BACKGROUND: Norfloxacin decreases the incidence of spontaneous bacterial peritonitis in cirrhotics, but promotes the appearance of quinolone-resistant Escherichia coli. AIM: : To define the characteristics of quinolone-resistant E. coli spontaneous bacterial peritonitis. METHODS: E. coli-positive ascitic fluid cultures were identified during a 6-year period. Data on quinolone-sensitive and quinolone-resistant E. coli spontaneous bacterial peritonitis were compared. RESULTS: One hundred and two E. coli-positive ascitic fluid cultures were detected. Cirrhotics accounted for 67 cases. Spontaneous bacterial peritonitis was found in 47 of the 67 (70%) cases [35 (74%) caused by quinolone-sensitive and 12 (26%) caused by quinolone-resistant E. coli]. Norfloxacin prophylaxis was higher in the quinolone-resistant group (92% vs. 6%, P < 0.001). Compared with patients with quinolone-sensitive E. coli spontaneous bacterial peritonitis, those with quinolone-resistant E. coli spontaneous bacterial peritonitis showed a higher prevalence of associated immunosuppressive factors (immunosuppressive drugs, human immunodeficiency virus infection or cancer) (92% vs. 20%, P < 0.001). Steroid therapy was independently associated with quinolone-resistant E. coli spontaneous bacterial peritonitis (odds ratio, 49; 95% confidence interval, 3.4-699; P = 0.004). The Child-Pugh score (P = 0.03), immunosuppression (P = 0.02) and renal failure (P = 0.01) were independent predictors of E. coli spontaneous bacterial peritonitis-related mortality. CONCLUSIONS: Associated immunosuppression is an important co-factor for the development of quinolone-resistant E. coli spontaneous bacterial peritonitis and for E. coli spontaneous bacterial peritonitis-related mortality.

Ciclopiroxolamine: in vitro antifungal activity against clinical yeast isolates.

The in vitro susceptibility of 225 clinical isolates of yeasts to ciclopiroxolamine (CPO) was compared with that of clotrimazole, econazole, ketoconazole, miconazole, tioconazole, fluconazole, itraconazole and nystatin using a standardized agar diffusion method (NeoSensitabs). Two hundred and eight strains of yeasts comprising 16 species of Candida and 22 strains belonging to other yeast genera were tested. One strain (0.4%) was resistant, four strains (1.8%) of intermediate susceptibility and 220 strains (97.3%) susceptible to CPO. More strains were susceptible to CPO than to the other antifungals studied. Susceptibility patterns of antifungal agents were not linked to species. The in vitro antifungal susceptibility profile of CPO was better than topical azole derivatives or fluconazole and itraconazole against a wide variety of clinically important yeasts.

Investigation of an outbreak of nosocomial infection due to a multiply drug-resistant strain of Pseudomonas aeruginosa.

A nosocomial outbreak of Pseudomonas aeruginosa infections which occurred in the Urology Service of a large city hospital was studied. A case-control methodology was used to analyse patients' characteristics and the main risk factors of all cases with a positive culture during the period between March 1987 and March 1988. The usefulness of factor analysis in the definition of a case was examined. There were 74 infections of which 35 (47.3%), had a nosocomial origin. The outbreak took place in December 1987, with a peak incidence of infections of 10.5%, compared with a 2.2% frequency during the preceding months (P less than 0.005). Six of the nine infections occurring in that month, were caused by strains resistant to ticarcillin and gentamicin. The epidemic cases had longer hospital stays than the non-epidemic cases (P less than 0.038) and occurred more frequently in a specific area of the hospital (P less than 0.001). The odds ratio for resistance to gentamicin was 15 (P less than 0.018) and that of resistance to ticarcillin, 127 (P less than 0.0001). Our results suggest that inaccurate case definitions may produce misleading conclusions. Factor analysis appears to be a useful analytical tool when defining a case.

Fluorometric determination of DNA and RNA in Chlamydomonas using ethidium bromide.

By using the fluorescence enhancement of ethidium bromide bound to nuclei acid, a very rapid, simple and sensitive assay of DNA in the green alga Chlamydomonas has been devised. Total fluorescence (DNA + RNA) was determined by complex formation with ethidium bromide in a cell lysate made by mixing cell samples with lauroyl sarcosinate, EDTA and NaOH and incubating the mixture for 5 min at room temperature followed by neutralization. For determination of DNA the RNA was digested by incubating the cell sample in te alkaline lysis solution for 45 min at 60 degrees C followed by neutralization, and complex formation with ethidium bromide. Quenching of the fluorescence due to cellular pigments was corrected for using an internal DNA standard.

Antifungal activity of amphotericin B and itraconazole against filamentous fungi: comparison of the Sensititre Yeast One and NCCLS M38--a reference methods.

The susceptibilities of 81 clinical isolates of Aspergillus spp., Fusarium spp., and Scedosporium spp., to amphotericin B and itraconazole were determined by the colorimetric microdilution method Sensititre and the reference microdilution method of NCCLS standard M38-A for filamentous fungi. No major discrepancies were found and agreement ranged between 86.4% to 84% and 69.1% to 86.4% for amphotericin B and itraconazole respectively at 48 h and 72 h of incubation by using the recommended endpoints. Within two two-fold dilutions, high levels of agreement were found in general for amphotericin B at 48 or 72 h (86.4 to 87.7%) and itraconazole (91.4 to 93.8%). Relatively better agreement was found for itraconazole at 72 h of incubation and 48 for amphotericin B.

[Is amphotericin B active against dermatophytes and Scopulariopsis brevicaulis?]. / Es activa la amfotericina B frente a hongos dermatófitos y Scopulariopsis brevicaulis?

The in vitro antifungal activity of amphotericin B was compared with that of griseofulvin, ketoconazole, clotrimazole and terbinafine in 193 clinical isolates of dermatophytes and Scopulariopsis brevicaulis. An agar diffusion method was used (NeoSensitabs) to categorize the susceptibility of the isolates as susceptible, intermediate or resistant to the antifungal agents. Using this method and following a standardized protocol adapted to the growth conditions of the dermatophytes and the opportunistic mold S. brevicaulis (inoculum size, temperature and time period of incubation), it was found that the in vitro susceptibility rates were 72%, 94.3%, 81.9%, 72% and 86% for amphotericin B, terbinafine, griseofulvin, ketoconazole and clotrimazole, respectively. Resistance percentages were 12.4%, 3.6%, 18.1%, 10.4% and 4.1% for the same antifungal agents. Amphotericin B showed no antifungal activity against S. brevicaulis; its activity against dermatophytes was similar to that of ketoconazole, and lower than that for clotrimazole and terbinafine.

[Activity of itraconazole against clinical isolates of Aspergillus spp. and Fusarium spp. determined by the M38-P NCCLS method]. / Actividad del itraconazol frente a aislamientos clínicos de Aspergillus spp. y Fusarium spp. determinada por el método M38-P del NCCLS.

The antifungal activity of itraconazole was studied in 101 clinical isolates of Aspergillus fumigatus, A. flavus, A. niger, A. terreus, A. nidulans, A. candidus, A. glaucus, A. clavatus, Fusarium solani, F. oxysporum and F. semitectum. The minimum inhibitory concentrations (MIC) were determined according to the protocol of the M38-P National Committee for Laboratory Standards (NCCLS) document using a microdilution method in 1640 RPMI liquid medium (visual reading at 48 and 72 h incubation). In general, the MIC did not vary with time of incubation, except in a Z. fumigatus strain in which the MIC went from 2 to 16 mg/l. The geometric mean of the MIC and MIC(90) of itraconazole for Aspergillus spp. was 0.44 mg/l and 0.5 mg/l, respectively; and for Fusarium spp. it was 14.1 mg/l and 16 mg/l, respectively. With 0.5 mg/l 75% of the Aspergillus spp. strains were inhibited, and 100% of these strains were inhibited with 2 mg/l. A. niger and A. fumigatus were the most resistant species (MIC(90) 2 mg/l). The MIC of all the Fusarium strains essayed was between 4 and 16 mg/l.

[Determination of the in vitro antifungal susceptibility of clinically important yeasts using the Sensititre system]. / Determinación mediante el sistema Sensititre de la sensibilidad in vitro a los antifúngicos de levaduras de interés médico.

Using Sensititre (AccuMed, USA) we studied the in vitro antifungal activity of amphotericin B, fluconazole, itraconazole, ketoconazole and 5-fluorocytosine against 250 clinical yeast isolates taken from different hospitals, including Candida (151 C. albicans, 15 C. krusei, 14 C. parapsilosis, 11 C. tropicalis, 10 C. glabrata, 4 C. guilliermondii, 3 C. rugosa, 2 C. viswanathii, 2 C. famata and 2 C. kefyr), Cryptococcus (32 C. neoformans and 1 C. laurentii), Trichosporon (2 isolates) and Rhodotorula rubra (1 isolate). All the strains were susceptible to amphotericin B and showed an MIC <1 mg/l. The susceptibility of C. albicans (MIC(90) <256 mg/l), C. krusei (MIC(90) <64 mg/l), C. glabrata (MIC(90) <64 mg/l) and C. neoformans (MIC(90) 32 mg/l) to fluconazole was lower (14% isolates being resistant and 16.8% susceptible depending on the dose). The largest number of strains resistant to itraconazole was observed in C. albicans and C. glabrata (17.2% resistant and 24% susceptible and susceptible depending on the dose, respectively). Ketoconazole and 5-fluorocytosine were not effective in vitro against 12.8% and 2%, respectively, of all the isolates studied. Nine C. krusei and seven C. neoformans (12.9%) showed dose-dependent susceptibility to 5-fluorocytosine.

[Treatment and outcome of pneumococcal meningitis in adults. Study of a recent series of 70 episodes]. / Terapéutica y evolución de la meningitis neumocócica en el adulto. Estudio de una serie reciente de 70 episodios.

BACKGROUND: Pneumococcal meningitis (PM) is an infection with high morbidity and mortality. The aim of this study was to evaluate the most relevant clinical, epidemiologic and evolutive characteristics of a recent series of adult patients with this disease. METHODS: Over a period of 10 years all the patients with PM diagnosed by isolation of this microorganism in the cerebrospinal fluid (CSF) were evaluated from a clinical, therapeutic and evolutive points of view. The impact of the new therapies in the disease and the variables associated with mortality were analyzed. RESULTS: Seventy episodes of PM were diagnosed, 60% being found in patients over the age of 50 years. The male/female relationship was 2/1. Fifty-three percent of the patients had other underlying diseases. Acute otitis media (AOM) was the source in 34% of the cases, in 11% the patients had a fistula of CSF and in 9% a pneumonia. At the time of diagnosis 74% of the patients had some degree of reduction in the level of consciousness and in 40% of the episodes the presence of neurologic local manifestations were observed. A decrease in sensitivity to penicillin was observed in 33% of the microorganisms isolated. Third generation cephalosporins were used as initial treatment in 57 episodes and penicillin in other 11 episodes. Adjuvant treatment with dexamethasone, mannitol and/or diphenylhydantoin was administered in 54% of the patients. Overall mortality was 23%: the factors associated with an unfavourable evolution were the existence of underlying disease, deep alteration in the level of consciousness at the time of diagnosis, the coexistence of pneumonia and the absence of adjuvant therapy. CONCLUSIONS: Mortality in pneumococcal meningitis is high. The most relevant risk factor is the initial degree of consciousness. Adjuvant therapies probably determine a reduction in the rate of mortality.

[Mallory-Weiss syndrome. Clinical cases and review of the literature]. / La sindrome di Mallory-Weiss. Casi clinici e revisione della letteratura.

Once considered rare, Mallory-Weiss syndrome is today more frequently reported due to the introduction of endoscopy which reveals this syndrome in up to 15% of hemorrhages of the upper digestive tract. The etiopathogenesis is not limited to the three factors reported by Mallory and Weiss in 1929: vomit, alcohol and hematemesis. An important role is also played by ASA and the like. This syndrome is also frequently associated with hiatus hernia in which it appears to be a complication since the lesion seems to be caused by the difference between intragastric (above all in the pocket of the hiatus hernia) and intrathoracic transmural pressure. Every increase in the pressure gradient at this level appears to cause fissuration at the cardioesophageal junction. Even endoscopy using rigid instruments and unsufflation may provoke the onset. Anamnesis and an objective examination, common to other pathologies, are not of great value to diagnosis. Radiology also contributes little, unless an arteriography is performed within the context of a highly selective angiography. Endoscopy is the prime method of diagnosis and, in addition to revealing the site and extent of hemorrhage, may be used to achieve hemostasis. Preendoscopic hemostasis currently uses a wide range of methods ranging from sclerotherapy to the injection of drugs or chemical substances, such as ethanol, adrenalin and thrombin; monopolar and bipolar electrocoagulation, thermal probe, hemoclips and Nd:YAG laser are also used. According to the majority of authors, the course of the syndrome is benign unless there are complications such as mediastinitis, pneumonia ab ingestis or hepatic insufficiency. The degree of bleeding is also decisive and the number of blood units transfused is of particular importance in determining the prognosis. The authors report a 10-year survival rate of approximately 70%.

[Symmetry, ptosis and a new infra-mammary border in the reconstruction of the breast with a tissue expander]. / Simmetria, ptosi e nuovo solco inframammario nella ricostruzione della mammella con tissue-expander.

The aim of this procedure is to obtain a permanent prosthesis (after mastectomy and the insertion of a tissue expander) that is similar to the contralateral breast in volume, morphology and inframammary border. The technique involves aspiration of the tissue expander fluid until the desired volume is obtained and the measurement of the fluid which indicates the volume of the prosthesis to be inserted. Given the satisfactory results obtained, the intention is to continue adopting this procedure.

[Lipoma of the small intestine as a rare cause of intestinal occlusion]. / Lipoma del tenue come rara causa di occlusione intestinale.

Lipoma is a benign tumour of mesenchymal origin which is not frequently localized in the gastroenteric tract; in anatomopathological statistics it is less rare: this is due to the fact that it rarely reaches dimensions which warrant surgical treatment. It is usually either an occasional finding during the course of laparotomy due to other motives or is the cause of complications, as in the present case of intestinal occlusion due to ileocolic invagination, resulting in emergency surgery. As a cause of occlusion tumours of the small bowel are second in terms of incidence to adhesive factors, volvuli and hernias. Invaginations account for 2/3 of small bowel occlusions caused by up to 80% of tumours: the lipoma is the most frequent benign tumour to cause invagination in its submucous polypoid and more or less scissile form. Symptoms are not specific and this causes a delay in diagnosis. Patients are often young subjects with a history of recurrent abdominal colic and sensitivity to anti-spastic drugs so much so that in the past they were diagnosed as "chronic colic" sufferers. Sometimes the only symptom is dyspepsia, or nausea and vomiting, or occasionally abdominal distension with constipation or attacks of diarrhoea. Radiology is not of great value in the diagnosis except for indicating the possible need for emergency surgery. There are no radiological tests, with or without contrast mediums, echography, CAT or MNR which can diagnose this pathology. The decision to operate is usually triggered by the presence of a complication, but perioperative extemporary histological tests are advisable for a correct surgical approach: if the form is scissile, segmentary resection of the small bowel is necessary.(ABSTRACT TRUNCATED AT 250 WORDS)

Risk factors perceived predictive of ISA spread in Chile: applications to decision support.

Aquaculture is anticipated to be a critical element in future solutions to global food shortage. However, diseases can impede industry efficiency and sustainability. Consequently, diseases can and have led to dramatic re-structuring in industry or regulatory practices. The emergence of infectious salmon anemia (ISA) in Chile is one such example. As in other countries, many mitigations were instituted universally, and many incurred considerable costs as they introduced a new layer of coordination of farming activities of marine sites within common geographic areas (termed 'neighborhoods' or 'barrios'). The aggregate response led to a strong reduction in ISA incidence and impact. However, the relative value of individual mitigations is less clear, especially where response policies were universally applied and retrospective analyses are missing 'controls' (i.e., areas where a mitigation was not applied). Further, re-focusing policies around disease prevention following resolution of an outbreak is important to renew sustainable production; though, again, field data to guide this shift in purpose are often lacking. Expert panels can offer timely decision support in the absence of empirical data. We convened a panel of fish health experts to weight risk factors predictive of ISA virus (ISAV) introduction or spread between Atlantic salmon barrios in Chile. Barrios, rather than sites, were the unit of interest because many of the new mitigations operate at this level and few available studies examine their efficacy. Panelists identified barrio processing plant biosecurity, fallowing strategies, adult live fish transfers, fish and site density, smolt quality, hydrographic connection with other neighborhoods, presence of sea lice (Caligus rogercresseyi), and harvest vessel biosecurity as factors with the greatest predictive strength for ISAV virulent genotype ('HPR-deleted') occurrence. Fewer factors were considered predictive of ISAV HPR0 genotype ('HPR0') occurrence, with greatest strengths assigned to fish and site density, adult live fish transfers, and smolt facility HPR0 status. Field validation based on ISAV and risk factor occurrence after panel completion generally supports expert estimates, and highlights a few factors (e.g., broodstock HPR0 status) less conclusive in the original study. Results inform legislation, industry best management practices and surveillance design.

[Pulmonary artery aneurism in a patient with Behçet disease. Report of one case]. / Aneurisma de la arteria pulmonar en Enfermedad de Behçet.

Behçet disease is a systemic disease with diverse clinical symptoms which vary according to the organs and systems involved. Typically, patients have oral and genital ulcers and episodic ocular involvement with periods of clinical improvement. We report an 18-year-old mole presenting with chest pain and hemoptysis and a history of ulcers in the oral cavity and scrotum. A chest CAT scan showed a mass located adjacent to the heart that a pulmonary arteriography defined as a left pulmonary artery aneurism. The patient was operated, excising left inferior pulmonary lobe. Due to skin and ocular involvement, the patient complied with criteria for Behçet disease. Immunosuppressive treatment with prednisone and azathioprine was started and the patient was discharged from the hospital.
