Herpes Zoster Ophthalmicus comprises 7% of all herpes zoster infection, 50% of those involving eyeballs, and is one disease entitiy with a very grave prognosis. We have experienced a 68-year-old man who visited the emergency room complaining of severe pain in his eye and headache with loss of vision. He was seen by neurosurgeons, dermatologists and ophthalmologists, and finally sent to the pain clinic for control of pain under the diagnosis of herpes zoster ophthalmicus. In spite of zealous treatment efforts, loss of vision, pain and infectious condition did not recover; and furthermore, due to severe infection, he had his eyeball extracted 100 days after the onset of diseases. 140 days after onset, contralateral hemiplegia accompanied the disease process. We present an unusual case of herpes zoster ophthalmicus with no treatment effect.

Superior orbital fissure syndrome is characterized by ophthalmoplegia, ptosis of the eye, reflex dilation of the pupil, and anesthesia of the upper eyelid and forehead. This syndrome may be the result of craniofacial fractures as well as neoplasms of the retrobulbar space, hematomas in the orbital muscle cone and retrobulbar space, and hematoma and infection of the cavernous sinus. A case of superior orbital fissure syndrome is described.

The current investigation dealing with the causative agent of mass mortalities in cultured Oreochromis niloticus. The diseased fish showed external hemorrhage, unilateral and bilateral eye opacity, ended by blindness and fish death. The postmortem lesions revealed congested friable kidney and spleen, and liver has yellow nodules. Obtained isolates were identified as Aeromonas hydrophila (the causative agent of Motile Aeromonas Septicemia) and found to be highly pathogenic as they contained hemolysin virulence gene causing mortality reached to 100 and 70% in intraperitoneal and intramuscular infection. The prevalence of MAS was 80% among the surveyed O. niloticus. Blood and serum were collected from naturally diseased, intraperitoneal and intramuscular injected O. niloticus for hematological and biochemical examination. Similarly, gills, musculature, kidney, liver and spleen were collected for histopathological evaluation, and micropathomorphological analysis of spleen was done. Macrocytic hypochromic anemia was recorded in the intraperitoneal infection. Serum protein, albumin and globulin were decrease only in naturally diseased fish. Leucocytosis with heterophilia and lymphocytosis were observed in naturally diseased and intraperitoneal infected fish. There were severe degenerative changes and hemorrhagic necrosis in the examined tissues which were more obvious in intraperitoneal than intramuscular infection. Activation and proliferation of melanocytes macrophages centers with severe hemosiderosis were recorded in spleen of naturally diseased and experimentally infected fish.

Acanthamoeba castellanii belonging to the T4 genotype may cause a fatal brain infection known as granulomatous amoebic encephalitis, and the vision-threatening eye infection Acanthamoeba keratitis. The aim of this study was to evaluate the antiamoebic effects of three clinically available antidiabetic drugs, Glimepiride, Vildagliptin and Repaglinide, against A. castellanii belonging to the T4 genotype. Furthermore, we attempted to conjugate these drugs with silver nanoparticles (AgNPs) to enhance their antiamoebic effects. Amoebicidal, encystation, excystation, and host cell cytotoxicity assays were performed to unravel any antiacanthamoebic effects. Vildagliptin conjugated silver nanoparticles (Vgt-AgNPs) characterized by spectroscopic techniques and atomic force microscopy were synthesized. All three drugs showed antiamoebic effects against A. castellanii and significantly blocked the encystation. These drugs also showed significant cysticidal effects and reduced host cell cytotoxicity caused by A. castellanii. Moreover, Vildagliptin-coated silver nanoparticles were successfully synthesized and are shown to enhance its antiacanthamoebic potency at significantly reduced concentration. The repurposed application of the tested antidiabetic drugs and their nanoparticles against free-living amoeba such as Acanthamoeba castellanii described here is a novel outcome that holds tremendous potential for future applications against devastating infection.

Cavernous sinus thrombosis is one of the major complications of abscesses of the maxillofacial region. The initial symptoms of CST are usually pain in the eye and tenderness to pressure. this is associated with high fluctuating fever, chills, rapid pulse, and sweating. Venous obstruction subsequently causes edema of the eyelids, lacrimation, proptosis, chemosis and retinal hemorrhages. Blindness is sometimes an accompaniment of cavernous sinus thrombosis when the infection also involves the orbit. There is also cranial nerve involvement (oculomotor, troclear, abducence) and ophthalmoplegia, diminished or absent corneal reflex, ptosis, and dilation of the pupil occur. The terminal stages bring signs of advanced toxemia and meningitis. Infections of the face can cause a septic thrombosis of the cavernous sinus. Furunculosis and infected hair follicles in the nose are frequent causes. Extractions of maxillary anterior teeth in the presence of acute infection and especially curettage of the sockets under such circumstances can cause this condition. The infection is usually staphylococcal. The inflection may spread directly through the pterygoid plexus of veins and the pterygomaxillary space and then ascend into the sinus or it may spread directly from the pterygopalatine space to the orbit. This is possible because of the absence of valves in the angular, facial, and ophthalmic veins. The treatment is empirical antibiotic therapy followed by specific anbibiotic therapy based on blood or pus culture. The inflection usually involves one side, however, it may easily spread to the opposite side through the circulus sinus. Unless it is treated early, the prognosis is poor even in this doses. Occasionally the antibiotics will not adequately resolve the septic thrombus, and death ensues. the use of anticoagulants to prevent venous thrombosis has been recommended, but the efficacy of such therapy has not been substantiated. Surgical access through eye enucleation has been suggested. We report a case which demonstrates cavernous sinus thrombosis by the infection after the functional neck dissection and the intraoral reconstruction with auriculomastoid fascio-cutaneous island flap.

Tuberculosis (TB) is an infectious disease caused by Mycobacterium tuberculosis. Bacillus Calmette-$Gu\acute{e}rin$ (BCG) vaccine is the only TB vaccine currently available, but it is not sufficiently effective in preventing active pulmonary TB or adult infection. With the purpose of developing an improved vaccine against TB that can overcome the limitations of the current BCG vaccine, we investigated whether adjuvant formulations containing de-O-acylated lipooligosaccharide (dLOS) are capable of enhancing the immunogenicity and protective efficacy of TB subunit vaccines. The results revealed that the dLOS/dimethyl dioctadecyl ammonium bromide (DDA) adjuvant formulation significantly increased both humoral and Th1-type cellular responses to TB subunit vaccine that are composed of three antigens, Ag85A, ESAT-6, and HspX. The adjuvanted TB vaccine also effectively induced the Th1-type response in a BCG-primed mouse model, suggesting a potential as a booster vaccine. Finally, the dLOS/DDA-adjuvanted TB vaccine showed protective efficacy against M. tuberculosis infection in vitro and in vivo. These data indicate that the dLOS/DDA adjuvant enhances the Th1-type immunity and protective efficacy of the TB subunit vaccine, suggesting that it would be a promising adjuvant candidate for the development of a booster vaccine.

The present study was performed to observe histopathological effects of Oculotrema hippopotami Stunkard, 1924 infection in the eye of Hippopotamus amphibius, as well as to reveal new details of morphology and structural features of this monogenean and its comparison between 2 age stages of the parasite. This was done using both light and scanning electron microscopy, energy dispersive X-ray analysis (EDXA) and histopathology. The presence of a mixture of different generations (adult and sub-adult) in one host individual is common for Oculotrema Stunkard, 1924 in contrast to Polystoma Zeder, 1800. New metrical and graphical information obtained for adults and sub-adults compared with the previous studies. Here we show the presence of genital papillae in adults, metrical data on the distal part of the vas deferens. SEM micrographs of sperm ejaculatory structures and information about the flattened dorsal side of the body provided for the first time. Histopathological changes, such as necrosis and hemorrhage in host tissues as a result of O. hippopotami attachment structures are described. Structural analysis of different body parts of O. hippopotami of both age groups are also included. We show qualitative differences in the presence of hardening ions (S, P, Ca) in attachment structures (oral and haptor suckers) that increase with the age of the worm. The presence of sub-adults and adults on the same host, together with high levels of infection without high pathogenicity may account for Oculotrema being one of the most successful parasites among the Monogenea.

1. King Hyeonjong(1641-1674) mainly suffered from eye disease and abscess. He specially took a hot spring bath for cure of eye and skin problems. He probably died of septicemia and the following gastro-intestinal infection at the age of 34, quite early for his age. 2. King Sukjong(1661-1720) was not very well all through his life, but lived quite longer than other Kings in the Joseon Dynasty. He suffered from various diseases like heart-based heat, abscess, edema, upper respiratory infections, etc. He frequently took the treatments of acupuncture and moxibustion. He presumably died of dysfunction of liver and kidney at the age of 60. 3. King Gyeongjong(1688-1724) suffered from political problems from birth to death, so he may have had excessive mental stress for his poor health. He mainly suffered from heart-based heat and abscess. It is quite not sure why he died in only one month from the onset of his symptoms, so many people thought that he was poisoned to death. He probably died of septicemia and the following gastro-intestinal infection at the age of 37. 4. King Yeongjo(1694-1776) lived for 83 years, which is the longest of all the Kings in the Joseon Dynasty. He mainly suffered from hypofunction of gastro-intestinal system with cold symptoms, coughs, uneasiness. He took various kinds of herbal medicine, of which he took ginseng the most. He is supposed to be dead due to his old age at 83.

이 연구는 치과감염에 대한 의료소비자들의 인식도를 파악하고자 대구지역 치과병원(3곳)에 내원하는 환자를 대상으로 설문조사하여 회수한 213부를 분석 하였다. 그 결과 가장 중요하게 생각하는 감염관리는 '기구소독'이 64.3%로 많았고, 연령에서 유의한 차이가 있었다(P<0.01). 감염관리 책임여부에 대해서는 72.3%가 '치과의사, 직원'의 책임이라고 답하였고 학력에서 유의하였다(P<0.001). 청결위생중요도에서는 70.0%가 '매우중요하다'고 답하였고, 성별(P<0.05)과 연령(P<0.01)에서 유의하게 나타났다. 치과 감염관리에 관한 정보습득 경험이 있는 사람이 없는 사람보다 손 씻기(P<0.001), 타액 흡입기 교체(P<0.001), 양치컵 교체(P<0.01)여부를 더 유심이 관찰하고, 보안경 착용여부도 더 중요하게 생각하는 것으로 조사되었다(P<0.01). 이상의 연구결과로 치과 의료기관은 보건복지부에서 고지하는 감염관리 평가를 잘 인지하고 일반 의료소비자들의 눈높이에 맞는 감염관리를 실천한다면 병원의 신뢰도는 물론 환자만족도까지 높일 수 있는 바탕이 될 것이라 생각된다.

Penetrating facial wounds are uncommon and are usually life threatening because of the possibility of brain damage. There are three possible pathways for penetrating the cranium through the orbit: via the orbital roof, via the superior orbital fissure, or between the optic canal and lateral wall of the orbit. Brain injuries resulting from the penetrating wounds show extensive parenchymal damage, hemorrhage, and brain edema. Transorbital penetrating wounds can lead to diverse lesions of the optical apparatus, including the eye globe, the optical nerve, and the chiasm. Moreover, intracerebral structures may be hurt, and bleeding and infection may occur. Early diagnosis and prompt debridement are the fundamental factors affecting the outcome of a penetrating facial wound. An 87-year-old man was admitted to the emergency department with a grinder impacted into the medial aspect of the right eye. On presentation, the man was fully conscious with a Glasgow Coma Scale score of 15 and complained of a visual disturbance of the right eye. Computed tomography demonstrated a right orbital medial and inferior wall fracture, a frontal bone fracture, and a contusional hemorrhage in frontal lobe of the brain. A craniotomy with hematoma removal and repair of the orbital floor was done. He showed no neurological deficits except right visual loss. This appears to be the first report of a man with a penetrating facial wound caused by a grinder, who presented with a potentially disastrous craniocerebral injury that did not lead to any serious neurological seguelae.
