Pulmonary tumor thrombotic microangiopathy (PTTM) is a rare but fatal complication of cancer and causes pulmonary hypertension and acute/subacute right heart failure. PTTM is most commonly associated with gastric cancer and more rarely associated with pancreatic cancer. We report a case of progressive right heart failure associated with clinically diagnosed pancreatic cancer, suggesting PTTM.

This paper describes a fatal case of pneumonia in a 14-day-old dog caused by extraintestinal pathogenic Escherichia coli (ExPEC). The necropsy showed that almost all of left lobes of the lungs had dark-red consolidation. A histopathology examination revealed moderate acute fibrino-hemorrhagic necrotizing pneumonia with intralesional bacterial colonies. Non-suppurative epicarditis, congestion in the liver, and necrosis in the white pulp of the spleen also were found. E. coli with cytotoxic necrotizing factor 1 and α-hemolysin was isolated from the lung. This case was confirmed to have fatal pneumonia caused by ExPEC that led to a systemic infection.

This experiment is to search what some chemicals polluting water have an effect on the Rana nigromaculata Hallowell, in the survival rate and the metamorphosis speed from a tadpole to a young frog. 1. The fatal thickness by some agricultural chemicals and copper sulfate is different from one another. The fatal rate in the contrast group is 15 percent, and particulary Dithane M-45 is the most among the all reagents. 2. The effect on the anamorphosis is very severe. In the case of contrast group, it appears to stage 25, but it is not to appear at the group used agricultural chemicals. 3. The less the thickness of that is, the less the influence of the survival rate and the metamorphosis speed. 4. The density of the agricultural chemical is in inverse proportion to the survival rate and the metamorphosis speed, and the other side, the fatal rate is proportion.

Epidural steroid injection(ESI) has been a commonly applied conservative therapy for the management of chronic low back pain and sciatica. However, there are many reports concerning various local, systemic and neurological complications related to ESI. We report two cases with fatal complications after ESI for low back pain and sciatica. In both patients, ventriculitis and meningitis were causative factors to be fatal. Aseptic procedures and careful post-procedure assessment are essential to avoid serious complications following ESI.

Few recent reports have indicated that Mycobacterium massiliense causes various infections including respiratory infection. However, there is scarce information on the clinical significance, natural history of the infection, and therapeutic strategy. This report describes a case of an immunocompetent old man infected by M. massiliense that causes acute respiratory failure. In light of the general courses of non-tuberculous mycobacterium infections, rapid progression and fatality are very rare and odd. In addition, we discuss the biological and pathological properties of M. massiliense with the review of cases reported previously including our fatal one.

Tetanus is a fatal disease caused by the infection Clostridium tetani found in animal feces and soil. It is a vaccine-preventable disease and rarely occurs in developed countries. However, approximately 30 cases still occur annually in South Korea. Tetanus, commonly called lockjaw, cause contraction of the masseter muscles in the early stage, resulting in trismus as the first symptom. As it progresses, spasm extends to various muscles in the face, neck, shoulder, and back, leading to distorted facial expression, dysphagia, backward arching of the body, dyspnea, and even death. Early diagnosis of tetanus is critical because it can quickly become fatal if left untreated. We present a case of trismus caused by tetanus and emphasize the importance of early diagnosis of acute trismus.

We report a case of fatal aortic tumor embolism presenting as acute paraplegia. A four-year-old girl was referred from a local hospital with sudden paraplegia and a poor medical condition. A neighbor had noticed her fall from a bike, and she could not walk. She had no previous illness. Emergency spine MRI revealed no remarkable findings. During the process of evaluation, her general condition deteriorated progressively. Chest and abdominal CT showed a large mass in the left lung field, and a diagnosis of aortic occlusion was made. An emergency transfemoral embolectomy was attempted. However, the patency of the aorta was not recovered. On pathological examination of tissues taken from the embolectomy, a pleuro-pulmonary blastoma was found. The patient died 22 hours after the onset of her symptoms. We describe a possible mechanism for the tumor embolism. To the best of our knowledge, this is the first case report of aortic occlusion caused by an embolic malignancy, presenting as acute paraplegia.

Herpes simplex virus [HSV] esophagitis is a rare disease and most of cases are reported in the immunocompromised patients. We report a case of fatal HSV infection started from herpes labialis and esophagitis. She had initially suffered from perioral ulcer, esophagitis, and interstitial pneumonitis later and eventually died of respiratory insufficiency one month later after the aneurysmal surgery. She did not have any immunocompromised medical history and also had no evidence of herpes encephalitis in laboratory study and magnetic resonance image [MRI]. With the availability of effective agents for the treatment of HSV infection, early recognition of HSV esophagitis is important because it may be clinically confused with Cushing ulcer and may be complicated with a fatal pneumonitis.

We present two fatal cases, a 41-year-old male (case 1) and his 8-year-old daughter (case 2), resulting from acute lidocaine poisoning. Lidocaine was quantified by gas chromatography (GC) analysis using nitrogen-phosphorus detection. The lidocaine concentrations of cases 1 and 2 were: liver, 27.7 $\mu$ g/g and 24.9 $\mu$g/g; spleen, 70.1 $\mu$g/g and 29.9 $\mu$g/g; and gastric contents, 23.6 $\mu$g/g and 42.8 $\mu$g/g, respectively.

Tortuosity of the internal carotid artery is not a rare condition. A 68-year-old woman presented with a 3 years' history of a pulsatile tinnitus and throat abnormal sensation. On physical examination, a soft pulsatile mass on the left posterior oropharyngeal wall was noted. By neck CT and neck MRI the tortuous internal carotd artery was visualized. Otolaryngologists should recognize this anomaly and the patient should be made aware of their condition, because it may cause a fatal or near-fatal hemorrhage during surgical procedures in the pharynx, especially tonsillectomy and adenoidectomy and drainage of peritonsillar abscess. We report a case of a left internal carotid artery tortuosity as an oropharyngeal mass.
