Presentation of penile incarceration with metal objects such as steel bushings or iron pipe is a recurrent worldwide phenomenon. Non-metallic thin objects are easy to remove but can cause severe injury. Metal objects are difficult to remove, but the injuries usually are less severe. Treatments are variable according to the level of penile trauma. We present an unusual case of an 87-year-old man with penile incarceration by both metal and plastic objects.

PURPOSE: We wanted to evaluate the usefulness of the inner hypoechoic band in pediatric appendices as an ultrasonographic criterion to exclude or confirm acute appendicitis. MATERIALS AND METHODS: Among the 169 consecutive children with right lower abdominal pain, the 149 appendices depicted on US were prospectively evaluated for an inner hypoechoic band in the appendiceal walls. The sensitivity, specificity, positive and negative predictive values and accuracy were assessed for loss of the inner hypoechoic band as a diagnostic criterion for acute appendicitis. RESULTS: The appendices in 12 (25%) patients with acute appendicitis show entire inner hypoechoic bands and those in 36 patients (75%) did not. The appendices in 97 (96%) patients without acute appendicitis showed entire inner hypoechoic bands, and those in 4 (4%) did not. The loss of inner hypoechoic band confirmed acute appendicitis with a sensitivity of 75%, a specificity of 96%, positive and negative predictive values of 89% and 90%, respectively, and an accuracy of 89%. The thickness of the inner hypoechoic band in patients without appendicitis was significantly higher than that in patients with appendicitis (p = 0.03). CONCLUSION: The visualization of entire thickened inner hypoechoic band in the appendiceal wall helps to rule out acute appendicitis. However, the loss of the inner hypoechoic band is suggestive of acute appendicitis.

The seasonal abundance of hard ticks that transmit severe fever with thrombocytopenia syndrome virus was monitored with a collection trap method every April to November during 2015–2018 and with a flagging method every July and August during 2015–2018 in Ganghwa-do (island) of Incheon Metropolitan City, Republic of Korea. This monitoring was performed in a copse, a short grass field, coniferous forest and broad-leaved forest. A total of 17,457 ticks (8,277 larvae, 4,137 nymphs, 3,389 females, and 1,654 males) of the ixodid ticks comprising 3 species (Haemaphysalis longicornis, H. flava, and Ixodes nipponensis) were collected with collection traps. Of the identified ticks, H. longicornis was the most frequently collected ticks (except larval ticks) (94.26%, 8,653/9,180 ticks (nymphs and adults)), followed by H. flava (5.71%, 524/9,180) and Ix. nipponensis (less than 0.04%, 3/9,180). The ticks collected with collecting traps were pooled and assayed for the presence of SFTS virus with negative results. In addition, for monitoring the prevalence of hard ticks, a total of 7,461 ticks (5,529 larvae, 1,272 nymphs, 469 females, and 191 males) of the ixodid ticks comprising 3 species (H. longicornis, H. flava, and Ix. nipponensis) were collected with flagging method. H. longicornis was the highest collected ticks (except larval ticks) (99.53%, 1,908/1,917 ticks (nymphs and adults)), followed by H. flava (1.15%, 22/1,917).

Owing to global climate change, the global resurgence of vector-borne infectious diseases and their potential to inflict widespread casualties among human populations has emerged as a pivotal burden on public health systems. Tsutsugamushi disease (scrub typhus) in the Republic of Korea is steadily increasing and was designated as a legal communicable disease in 1994. The disease is a mite-borne acute febrile disease most commonly contracted from October to December. In this study, we tried to determine the prevalence of tsutsugamushi disease transmitted by chigger mites living on rodents and investigated their target vector diversity, abundance, and distribution to enable the mapping of hotspots for this disease in 2015. A total of 5 species belonging to 4 genera (109 mites): Leptotrombidium scutellare 60.6%, L. pallidum 28.4% Neotrombicula tamiyai 9.2%, Euschoengastia koreaensis/0.9%), and Neoschoengastia asakawa 0.9% were collected using chigger mite collecting traps mimicking human skin odor and sticky chigger traps from April to November 2015. Chigger mites causing tsutsugamushi disease in wild rodents were also collected in Hwaseong for the zoonotic surveillance of the vector. A total of 77 rodents belonging to 3 genera: Apodemus agrarius (93.5%), Crocidura lasiura (5.2%), and Micromys minutus (1.3%) were collected in April, October, and November 2015. The most common mite was L. pallidum (46.9%), followed by L. scutellare (18.6%), and L. orientale (18.0%). However, any of the chigger mite pools collected from rodent hosts was tested positive for Orientia tsutsugamushi, the pathogen of tsutsugamushi disease, in this survey.
