High resolution computed tomography (CT) of the middle ear and mastoid, when properly performed and interpreted, is valuable to the otologic surgeon prior to exploration of the cholesteatomatous ear. Fifty one patients with cholesteatomatous otitis media underwent CT examination of both ears one to four weeks prior to surgery. These CT findings were then compared with operation findings. We analysed sixteen parameters of the anatomical and pathological features of the temporal bone affected by cholesteatoma. In conclusion, a high degree of correct correlation was noted between CT findings and those of the operation. Our study showed the usefulness and accuracy of preoperative computed tomographic study in cholesteatomatous otitis media.

The incidence of duodenal diverticulum found incidentally during upper gastrointestinal roentgenographicexamination varies between 2% and 5%. The majority of cases occur along the medial aspect of the second portion of the duodenum, within 2.5cm of the ampulla of Vater. The majority of duodenal diverticula are asymptomatic, but insome cases, complications such as diverticulitis, hemorrhage, perforation, and fistula formation occur in thethird and fourth portions of the duodenum. We describe a case of giant diverticulum of the transverse duodenum,revealed by UGI and angiography, massive gastrointestinal bleeding in a 80-year-old patient.

Cutaneous larva migrans (CLM) is a rare serpiginous cutaneous eruption caused by accidental penetration and migration in the skin with infective larvae of nematode that normally do not have the human as their host. Although CLM has a worldwide distribution, the infection is most frequent in warmer climates. More recently, they have been increasingly imported from the tropics or subtropics by travelers. We experienced two patients who had pruritic serpiginous linear eruption in their skin for a few weeks after traveling to the endemic areas (Brazil and Thailand, respectively). After the treatment with albendazole, the skin lesions resolved with post-inflammatory hyperpigmentation. We report herein two cases of cutaneous larva migrans successfully treated with albendazole.

Coronavirus disease 2019 (COVID-19) is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which is affiliated with the β-coronavirus subgroup, which includes SARS-CoV and Middle East respiratory syndrome coronavirus (MERS-CoV), but is far more infectious than the 2. Because it is potentially life-threatening to infants and pregnant women with weak immune systems, clinical manifestations and vertical transmission of COVID-19 are matters of interest. Staff of the obstetrics department of university hospitals in Daegu and of the Daegu metropolitan government designated Daegu Fatima Hospital for the delivery of pregnant women with suspected and confirmed SARS-CoV-2 infection. Thirteen pregnant women with laboratory-confirmed COVID-19 were identified. Among them was a 28-year-old pregnant woman who had recovered from COVID-19 and had given birth to a healthy girl at 38 weeks of gestational age. We present our uncommon experience with a brief review of literatures.

Determining blood loss [100% – RBV (%)] is challenging in the management of haemorrhagic shock. We derived an equation estimating RBV (%) via serial haematocrits (Hct1 , Hct2 ) by fixing infused crystalloid fluid volume (N) as [0.015 × body weight (g)]. Then, we validated it in vivo. Mathematically, the following estimation equation was derived: RBV (%) = 24k / [(Hct1 / Hct2 ) – 1]. For validation, nonongoing haemorrhagic shock was induced in Sprague–Dawley rats by withdrawing 20.0%–60.0% of their total blood volume (TBV) in 5.0% intervals (n = 9). Hct1 was checked after 10 min and normal saline N cc was infused over 10 min. Hct 2 was checked five minutes later. We applied a linear equation to explain RBV (%) with 1 / [(Hct1 / Hct2 ) – 1]. Seven rats losing 30.0%–60.0% of their TBV suffered shock persistently. For them, RBV (%) was updated as 5.67 / [(Hct1 / Hct2 ) – 1] + 32.8 (95% confidence interval [CI] of the slope: 3.14–8.21, p = 0.002, R2 = 0.87). On a Bland-Altman plot, the difference between the estimated and actual RBV was 0.00 ± 4.03%; the 95% CIs of the limits of agreements were included within the pre-determined criterion of validation (< 20%). For rats suffering from persistent, non-ongoing haemorrhagic shock, we derived and validated a simple equation estimating RBV (%). This enables the calculation of blood loss via information on serial haematocrits under a fixed N.Clinical validation is required before utilisation for emergency care of haemorrhagic shock.

BACKGROUND: Several clinical scoring systems are currently being used to predict the outcome of sepsis, but they all have certain limitations. Therefore, we sought to identify the proteomic biomarkers, with wsing proteomic tools, that differed according to the outcome of sepsis patients. METHODS: Upon admission to the ICU, blood samples were obtained from the 16 patients with sepsis who were enrolled in this study. Surface-enhanced laser desorption/ionization time-of-flight mass spectrometry (SELDI-TOF MS) was used to identify the markers that could predict the outcome of sepsis. RESULTS: We found six peaks, by using cation and anion chips, that statistically differed between those patients who died and those who survived. CONCLUSION: The biomarkers we found by using proteomic tools may help predict the prognosis and also plan the treatment of sepsis.

BACKGROUND: The pathological features in asthmatic airway remodeling are diverse. The aim of this study was to examine the degree of airway vascularity in relation to the other remodeling parameters in asthmatics. METHODS: Bronchial biopsies were done in 34 asthmatic patients, and 6 control subjects. The basement membrane thickness and the subepithelial thickness were measured in the hematoxylin-eosin stained tissue, and the degree of vascularity was measured using type IV collagen immunostaining. RESULTS: 1) Compared to the control subjects, the asthmatics showed a significant increase in the basement membrane thickness (6.92+/-2.01micrometer vs 9.67+/-2.84micrometer, p<0.05) and the subepithelial thickness (44.49 +/- 31.92micrometer vs 121.22+/-72.79micrometer, p<0.05). 2) Compared to the control subjects, the asthmatics showed a significant increase in the vascular area per unit submucosal area (4.51+/-2.13% vs 10.32+/-6.08%, p<0.05). In addition, the number of vessels per unit submucosal area showed an increased tendency without statistical significance. 3) In the asthmatics, the number of vessels and the vascular area per unit submucosal area showed no correlation with the basement membrane thickness, the subepithelial thickness, the severity, the forced expiratory volume in 1 second(FEV1), and the methacholine provocative concentration 20(PC20). CONCLUSION: This study showed that vascularity was an important parameter in asthmatic airway remodeling but it was not related to the other remodeling parameters such as the basement membrane thickness and the subepithelial thickness. Each of these asthmatic remodeling parameters may have a different clinical significance. Therefore, further studies will be needed.

Retrograde jejunogastric intussusception is a rare complication following Billroth ll gastric surgery. It is a segmental invagination of a jejunal loop into the stomach through stoma. Clinical manifestations are epigastric pain, vomiting with bile or blood, and a palpable mass in the epigastrium. Gastroscopy and a upper GI (UGI) series are very helpful in the diagnosis of this disease. Although the management of this disease is usually surgical, when endoscopic reduction has failed, surgery should be immediately done because of the high mortality. We present here a case of jejunogastric intussusception that was diagnosed by gastroscopy in a patient with a history of Billroth ll surgery that had been done 6 years prior due to gastric cancer.
