BACKGROUND: Pulmonary complications including pneumonia and pulmonary edema frequently develop in critically ill surgical patients. Lung ultrasound (LUS) is increasingly used as a powerful diagnostic tool for pulmonary complications. The purpose of this study was to report how LUS is used in a surgical intensive care unit (ICU). METHODS: This study retrospectively reviewed the medical records of 67 patients who underwent LUS in surgical ICU between May 2016 and December 2016. RESULTS: The indication for LUS included hypoxemia (n = 44, 65.7%), abnormal chest radiographs without hypoxemia (n = 17, 25.4%), fever without both hypoxemia and abnormal chest radiographs (n = 4, 6.0%), and difficult weaning (n = 2, 3.0%). Among 67 patients, 55 patients were diagnosed with pulmonary edema (n = 27, 41.8%), pneumonia (n = 20, 29.9%), diffuse interstitial pattern with anterior consolidation (n = 6, 10.9%), pneumothorax with effusion (n = 1, 1.5%), and diaphragm dysfunction (n = 1, 1.5%), respectively, via LUS. LUS results did not indicate lung complications for 12 patients. Based on the location of space opacification on the chest radiographs, among 45 patients with bilateral abnormality and normal findings, three (6.7%) and two (4.4%) patients were finally diagnosed with pneumonia and atelectasis, respectively. Furthermore, among 34 patients with unilateral abnormality and normal findings, two patients (5.9%) were finally diagnosed with pulmonary edema. There were 27 patients who were initially diagnosed with pulmonary edema via LUS. This diagnosis was later confirmed by other tests. There were 20 patients who were initially diagnosed with pneumonia via LUS. Among them, 16 and 4 patients were finally diagnosed with pneumonia and atelectasis, respectively. CONCLUSIONS: LUS is useful to detect pulmonary complications including pulmonary edema and pneumonia in surgically ill patients.

BACKGROUND:With the application of early reperfusion by thrombolysis after acute MI, the importance of nontransmural infarction is increasing. We evaluated 1) the changes of LV dimension, LV fibrosis and transforming growth factor-beta1 (TGF-beta1) mRNA expression in a rat model of nontransmural infarction and 2) effects of angiotensin converting enzyme inhibitor (ACEI) and angiotensin II receptor blocker (ATRB) treatment after nontransmural infarction. METHOD AND RESULTS: Female Sprague-Dawley rats were subjected to 45 minutes of coronary occlusion followed by reperfusion, and at 5 days after the operation, animals were randomized to untreated (MI-vehicle, n=19), captopril-treated (MI-captopril, n=15) and losartan-treated (MI-losartan, n=14) groups. LV dimension, measured by transthoracic echocardiography, was significantly increased at 26 days after MI, and both captopril and losartan treatment inhibited LV cavity dilatation (LV end-diastolic dimension (mm): MI-vehicle, MI-captopril, MI-losartan; 8.6 +/- 0.2, 7.8 +/- 0.2, 8.0 +/- 0.2, p<0.05 vs. MI-vehicle each). Interstitial fibrosis was reduced with both captopril and losartan treatment (p<0.05 vs. MI-vehicle). TGF-beta1 mRNA increased 2.6 fold at 10 days (p<0.05 vs. pre-MI), and normalized at 26 days after nontransmural MI. Captopril and losartan treatment blocked the induction of TGF-beta1 expression after nontransmural MI (p=S vs. pre-MI). CONCLUSION: After large nontransmural MI, ACEI and ATRB treatments attenuate LV remodeling and decrease interstitial fibrosis, at least partly by blocking the acute induction of TGF-beta1 mRNA expression.

PURPOSE: To describe the clinical evaluation of corneal ectasia after laser in situ keratomileusis (LASIK) and evaluate risk factors. METHODS: Sixteen patients (21 eyes) who had undergone LASIK with corneal ectasia from 1997 to 1999 were reviewed retrospectively. The uncorrected visual acuity, best-corrected visual acuity (BCVA), spherical equivalent (SE), pachymetry, keratometry, intraocular pressure (IOP) and corneal topography were measured before and after LASIK. The targeted residual bed thickness (TRBT) and the ablation percentage of the total corneal thickness were checked. To determine risk factors, we reviewed 60 eyes with uneventful LASIK for 4 years after LASIK. The control group was selected with matched preoperative SE and TRBT similar to the ectasia group. RESULTS: Five (31.3%) of 16 patients developed ectasia bilaterally and the rate of preoperative asymmetric bow-tie pattern was 64.7% in corneal topography. At the final post-LASIK follow-up, disagreement of apices location on anterior and posterior was 33.3% in the right eye and 50.0% in the left eye. The mean time to onset of ectasia was 26.9 15.1 months and 28.6% developed ectasia after more than 40 months after LASIK. In the ectasia group, pachymetry before LASIK, TRBT and pachymetry at postoperative 2 months were thinner than the control group (p<0.05). CONCLUSIONS: Asymmetric bow tie pattern showed a high frequency in the corneal topography of the ectasia group before LASIK and about 1/3 of the cases developed ectasia more than 3 years after LASIK. The incidence of pachymetry before and after LASIK and TRBT was related to the development of ectasia.

BACKGROUND: Gabapentin decreases acute nociceptive pain in animal and human studies when given before surgical incision. Various doses of gabapentin have been used (300-1,200 mg) to measure this preemptive effect. Here, we evaluated the optimal dose of gabapentin for reducing fentanyl consumption and the adverse effects of gabapentin following gynecologic surgery. METHODS: We recruited 100 patients who underwent laparotomy for gynecologic surgery. Patients were randomly divided into 4 groups and received a placebo (control), gabapentin 300 mg (G 300), gabapentin 600 mg (G 600), or gabapentin 1,200 mg (G 1200) 2 h before surgery. Postoperatively, patients received fentanyl via an intravenous patient controlled analgesia device. The cumulative fentanyl doses were recorded 2, 6, 12, 24 h, and 48 h postoperatively, and the sedation scale was recorded in the post anesthetic care unit (PACU). RESULTS: The postoperative fentanyl requirement was lower with gabapentin treatment, but there was no significant differences for the different doses. PACU sedation scores were not different in any group. CONCLUSIONS: Gabapentin has a preemptive effect in gynecologic surgery, but there were no additional fentanyl-sparing benefits at doses above 300 mg. Thus, 300 mg is an optimal dose for decreasing fentanyl consumption following gynecologic surgery.

BACKGROUND AND OBJECTIVES: Methicillin resistant staphylococcus aureus (MRSA) prevalence has increased over the world during past several decades and now it has become a world wide problem. It is especially more serious in domestic situations but unfortunately, until this time, there is no report about MRSA infection treatment after endoscopic sinus surgery (ESS). The objective of our study is to evaluate clinical feature of MRSA infection and to find out what kinds of treatment is the best way to control of the MRSA infection after ESS. SUBJECTS AND METHOD: The medical records of 58 patients who had the evidence that they were infected with MRSA after ESS were retrospectively reviewed. Samples were obtained by sinus endoscopy in the office base. RESULTS: Those of MRSA infected only cases were 26 cases. Co-infected cases with another microorganism were 32 cases. Forty-three cases were treated with oral rifampin alone and 11 cases were treated by a combination with oral quinolone or trimethoprim-sulfimethoxazole. Four cases failed to be treated with oral antibiotic therapy. CONCLUSION: Rifampin is the useful medication for the treatment of MRSA infected patients who had underwent ESS. Also, Rifampin is a cost effective medication compared with the glycopeptide antibiotics especially if it is used in the office base.

Objective: This study aims to identify the usefulness of voice function in early screening for dysphagia. We sought to evaluate if screening tests through the functions of production and quality of voice were correlated with aspiration in dysphagic patients. Methods: This study involved 55 participants who were referred to videofluoroscopic swallowing study (VFSS) for suspected dysphagia. Blinded examiners rated the voice production function (MVI, MPT) using a portable instrument and evaluated the quality of voice (jitter, shimmer, NHR) using Visi-pitch. Swallowing functions were also evaluated by utilizing the penetration-aspiration scale (PAS), American Speech-Language-Hearing Association (ASHA), National Outcome Measurement System (NOMS) swallowing scale and VDS. The patients were divided into two groups, the penetration group, and the aspiration group according to the PAS score. The difference in variables was analyzed using the Mann-Whitney U test between the two groups. The relationship between voice parameters and swallow-related parameters was determined using the Spearman correlation coefficient. In addition, the cut-off, sensitivity, and specificity of meaningful variables in silent aspiration were analyzed using the ROC curve analysis. Results: The functions of production and quality of voice were found to be significantly different between the penetration and aspiration groups (P＜.000). The PAS score was correlated with all parameters of the functions of production and quality of voice (P＜.001). VDS was correlated with MVI, ASHA was correlated with MVI, and Shimmer (P＜.001). The meaningful variables for silent aspiration were jitter and shimmer. Conclusion Through a clinical screening test, it may be possible to predict the difference between penetration and aspiration through the functions of production and quality of voice.

BACKGROUND: Cutaneous pustular disorders include generalized pustular psoriasis (GPP) and acute generalized exanthematous pustulosis (AGEP). OBJECTIVE: To identify differences between GPP and AGEP, here we immunohistochemically evaluated interleukin (IL)-36 and the IL-23/Th17 axis. METHODS: This retrospective comparative immunohistochemical study was completed using 11 biopsies of 11 cases of GPP and 11 biopsies of 11 cases of AGEP. Through staining with the anti-IL-36-alpha (IL-36α), anti-IL-36 receptor antagonist (IL-36Ra), anti-nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB), anti-IL-23, anti-IL-17, and anti-IL-8 antibodies, main expression location and intensity were visualized in the epidermis and dermis. RESULTS: In both diseases, diffuse IL-36α expression was observed in the epidermis. IL-36Ra expression was observed in the dermal perivascular area as well as in the epidermis. NF-κB expression was observed in the epidermis and perivascular dermal area. Diffuse IL-23 and IL-17 expression was seen in the whole epidermis and the perivascular dermal area. IL-8 was expressed in the subcorneal pustules and parakeratotic area. Contrary to other cytokines, IL-23 expression in the epidermis of patients with GPP was more intense than only that in patients with AGEP. CONCLUSION: Common pathomechanisms might exist in the development of GPP and AGEP based on these immunohistochemical results, but further studies are needed.

PURPOSE: To observe the result of wavefront-guided (WFG) LASIK and investigate the ocular high order aberrations of WFG LASIK compare with conventional LASIK. METHODS: The uncorrected visual acuity (UCVA), manifest refraction, total high order aberration, coma and spherical aberration in 22 eyes of 13 patients who had undergone WFG LASIK were measured preoperative and at 1, 3 and 6 months postoperatively. The ocular high order aberrations of 19 eyes from 11 patients who had undergone convetional LASIK were measured at 6 months after surgery. The ocular high order aberrations of the WFG LASIK and conventional LASIK groups were compared. RESULTS: In the WFG LASIK group, the UCVA and spherical equivalent increased from 0.06 to 1.08 and from -6.13D to -1.16D, respectively after 6 months. The total high order aberration and coma (RMS) were 0.40 and 0.31 in conventional LASIK and 0.28 and 0.16 in WFG LASIK after 6 months. There was a statistically significant difference (p<0.05). CONCLUSIONS: The clinical outcomes of wavefront-guided LASIK by 6 months were a stable improvement in the visual acuity and a correction of all the optical aberrations of the eye. The postoperative high order aberration was significantly smaller than that in the conventional LASIK group.

A 21-month-old girl with cri-du-chat syndrome in conjunction with developmental delay underwent brain magnetic resonance imaging (MRI). The MRI showed hypoplasia of the brain stem, a normal cerebellum, thinning of the corpus callosum, and a lack of myelination in both anterior limbs of the internal capsule. She also had neonatal bilateral subependymal cysts. We believe that the symmetrical lack of myelination in both anterior limbs of the internal capsule could be a diagnostic clue of cri-du-chat syndrome.
