RESUMO
BACKGROUND: Chronic cavitary pulmonary disease and laryngeal involvement are unusual manifestations of Histoplasmosis capsulatum infection, particularly in patients who are not immunocompromised. The presence of fibro-cavitary lesions has been reported as a radiologic presentation of chronic histoplasmosis in patients with pre-existing lung disease. However, there have been few reports of extensive basal predominant cavitary lesions that mimic cystic-bronchiectasis. CASE PRESENTATION: A 65-year-old previously healthy Thai male presented with productive cough, hoarseness, low-grade fever, and weight loss for 6 months. There was no history of significant exposure to Histoplasmosis capsulatum. Tests for HIV and anti-IFN- γ antibody were negative. Chest CT revealed multifocal thick wall cavities, which were distributed in a peri-bronchial pattern, and some areas of consolidation in both basal lungs. Laryngoscopy revealed an ulcerative lesion of the false vocal cords. Histopathological study of false vocal cords and lung tissue showed granulomatous inflammation with mixed inflammatory cell infiltration and aggregation of histiocytes containing round intracytoplasmic organisms. GMS-staining was positive, but negative mucicarmine-staining was negative. A real-time PCR assay of the lung tissue was positive for Histoplasmosis capsulatum. The final diagnosis was chronic cavitary pulmonary histoplasmosis with laryngeal involvement. CONCLUSION: Chronic cavitary pulmonary histoplasmosis is rare, as is laryngeal involvement. However, there have been such cases in endemic areas, even in immunocompetent patients. Chronic histoplasmosis should be considered in patients who present with the extensive basal predominant cavitary-pulmonary lesions that mimic cystic bronchiectasis.
RESUMO
BACKGROUND: Ventilator-associated pneumonia (VAP) is a common nocosomial infection in intensive care unit (ICU). Local microbiological surveillance of pathogens and resistance patterns for early-onset VAP (EOVAP) and late-onset VAP (LOVAP) will help to choose appropriate empiric antibiotics. OBJECTIVE: To compare the multi-drug resistant (MDR) pathogens, treatment outcomes, and factors associated with hospital mortality of VAP. METHOD: A cross-sectional study between 1 January 2015 and 31 December 2017 at Srinagarind hospital, Khon Kaen University was conducted. The demographic data, causative pathogens, hospital length of stay (LOS), ICU LOS, mechanical ventilator (MV) days, and hospital mortality were retrospectively reviewed. RESULTS: One hundred and ninety patients were enrolled; 42 patients (22%) were EOVAP and 148 patients (78%) were LOVAP. Acinetobacter baumannii was the most common pathogen in both groups (50% EOVAP vs 52.7% LOVAP). MDR pathogens were significant greater in LOVAP (81.8%) than EOVAP (61.9%) (p = 0.007). The EOVAP had a significantly better ICU LOS [median (interquartile range, IQR) 20.0 (11.0, 30.0) vs. 26.5 (17.0, 43.0) days], hospital LOS [median (IQR) 26.5 (15.0, 44.0) vs. 35.5 (24.0, 56.0) days] shorter MV days [median (IQR) 14.0 (10.0, 29.0) vs. 23.0 (14.0, 35.5) days] and lower hospital mortality (16.7% vs 35.1%) than LOVAP (p < 0.05). The factor associated with hospital mortality was having simplified acute physiology (SAP) II score ≥ 40 with an adjusted odds ratio (aOR) of 2.22 [95% confidence interval (CI), 1.08-4.54, p = 0.02]. CONCLUSION: LOVAP had significantly higher MDR pathogens, MV days, ICU LOS, hospital LOS and hospital mortality than EOVAP. A broad-spectrum antibiotic to cover MDR pathogens should be considered in LOVAP. The factor associated with hospital mortality of VAP was a SAPII score ≥ 40.

STUDY OBJECTIVES: A telemonitoring system is a promising wireless technology that possibly enhances adherence to CPAP therapy. The study aimed to determine the effect of a telemonitoring system on CPAP therapy adherence among Asian patients with moderate-to-severe OSA. METHODS: A prospective randomized controlled trial enrolled 60 Asian adults (70% male) with moderate-to-severe OSA. Thirty patients each were randomized to a group using CPAP with a telemonitoring system or a group using CPAP with usual care. The telemonitoring system functioned by transferring CPAP-usage data via cellular network. When there were any triggers occurring 2 nights consecutively (usage hours < 4 hours per night; leakage > 27 L/min or AHI > 5 events/h), the investigator contacted the patients. The primary outcome was the 4-week CPAP usage hours per night. The secondary outcomes included the percentage of good adherence (defined as a 4-week period of therapy with CPAP usage > 4 hours/night on > 70% of total days), median leakage per night, adverse events from CPAP therapy, sleep quality improvement, and daytime sleepiness reduction. RESULTS: The mean AHI was 50.3 events/h. The mean 4-week CPAP usage hours per night were insignificantly higher in the telemonitoring group (5.16 ± 1.47 hours/night vs 4.42 ± 1.91 hours/night; P = .18). However, the percentage of good adherence was significantly higher in the telemonitoring group (64.2% vs 34.4%; P = .024). Median leakage per night was also significantly lower in the telemonitoring group. Furthermore, significant sleep quality improvement was observed in the telemonitoring group. Overall adverse events and daytime sleepiness reduction were not different. CONCLUSIONS: The telemonitoring system implementation showed a trend toward increasing CPAP nightly usage hours and significantly improved adherence and sleep quality among Asian patients with moderate-to-severe OSA.

We report a case of COVID-19 in kidney transplant patient in Thailand. A 58-year-old 2 years post-kidney transplant recipient, with maintenance immunosuppression of tacrolimus, mycophenolate mofetil (MMF), and prednisolone, presented with acute diarrhea which followed by fever on day 12. Symptoms of pneumonia together with lymphopenia from complete blood count were developed on day 7 after onset of fever with the x-ray finding of bilateral multifocal patchy infiltration. COVID-19 infection has been confirmed by reverse real-time polymerase chain reaction (PCR) in nasal swab as well as found in stool. Darunavir together with ritonavir, hydroxychloroquine, azithromycin, and favipiravir was initiated on the first day of admission at primary hospital. Patient has been transferred to our hospital on day 2 of admission in which tacrolimus together with MMF was discontinued. High-flow nasal cannula oxygen therapy was required on days 4-5 of hospitalization. Tocilizumab was administered after rising of serum IL-6 level. Symptoms of pneumonia were improved in which no oxygen treatment required from day 10 of hospitalization. Drug interaction between tacrolimus and anti-viral treatment leads to severely high level of tacrolimus which caused reversible acute kidney injury (AKI) after supportive treatment.

Granulomatous polyangiitis (GPA) is a multiple systemic necrotizing vasculitis. Diagnosis of pulmonary nodules in GPA is still challenging in clinical practice, however, other extrapulmonary manifestations, serology, and histopathology may help the diagnosis of GPA. This case series was of limed GPA with one of the largest pulmonary nodules which had a poor treatment response in contrast with previous literature.
RESUMO
Multiple myeloma (MM) is a hematologic malignancy of plasma cell origin. Incidence of pleural effusion in multiple myeloma patients is approximately 6%. Myelomatous pleural effusions (MPE) are rare and occur in less than 1% of all MM cases. MPE is associated with advanced diseases, decreased survival time, and poor treatment response. In our case report, we describe a 59-year old man who presented with MPE at the initial diagnosis of MM. A diagnosis of MPE was reach through pleural fluid cytology and pleural tissue histology. The MPE had good response to initial dexamethasone without local therapy.
