  • Coccidioidomycosis is a fungal infection caused by the soil fungus, Coccidioides immitis, which is endemic to the south-western United States. However, the incidence of coccidioidomycosis has recently increased due to the increase in overseas travel to endemic areas. We report a case of pulmonary coccidioidomycosis diagnosed in an immunocompetent person. A 28-year-old female, who had lived in Phoenix, Arizona, USA for 2 years, was admitted for an evaluation of persistent cough with fever lasting for 2 weeks. The chest X-ray and Chest CT revealed multifocal patchy consolidation and ground-glass opacity in both lungs as well as multiple enlarged right hilar and paratracheal lymph nodes. A percutaneous needLe biopsy of the main mass-like consolidation confirmed mature spherules of Coccidioides immitis in lung tissue. Pulmonary coccidioidomycosis should be considered in patients presenting with persistent cough with fever and a history of travel to or immigration from an endemic area.

  • Background: Skin biopsy is the method to assist clinicians to make definite dermatological diagnosis which further helps in holistic management. Skin cancers are relatively rare clinical diagnosis in developing countries like Nepal, but the prevalence is on rise. Objectives: To investigate the profile of skin biopsies and frequencies and pattern of skin cancers in a tertiary care centre of Western Nepal. Materials and Methods: The materials consisted of 434 biopsies (1.37%) out of 31,450 OPD visits performed in the Department of Dermatology, Manipal Teaching Hospital, Pokhara, Nepal, during the period of Dec 2011-Nov 2014. Data were collected and analyzed using SPSS-16 with reference to incidence, age, sex, race and clinical and histopathological features. Results: The commonest disorders observed in biopsies were papulosquamous lesions, skin tuberculosis of different types, benign skin tumors, leprosy, collagen and fungal diseases. Viral diseases were rarely seen, probably due to straight forward clinical diagnosis. Dermatological malignancies accounted for 55/434 (12.67%) of biopsies. Skin disorders in general were commoner in females 280/434 (64%), including malignancies 32/55(58.2%). Mean age of patients with skin cancer was 54.5 years. Facilities for proper laboratory investigation of dermatological disorders will improve the quality of life. Conclusions: The most prevalent lesion in skin biopsies was papulosquamous disorders followed by skin tuberculosis of different types. Dermatological malignancy constituted 55/434 (12.67%) cases. The prevalence of skin malignancy is on rise in Nepalese society probably due to increase in life expectancy and better diagnostic services.

  • Hexanal, a C-6 aldehyde has been implicated to have antimicrobial properties. Hence, this study was conducted to determine the antifungal activities of hexanal vapor against major postharvest pathogens of banana viz., Colletotrichum gloeosporioides and Lasiodiplodia theobromae. The pathogens were cultured in vitro and exposed to hexanal vapor at 600, 800, 1,000 and 1,200 ppm. Mycelial growth of both fungal pathogens were inhibited completely at 800 ppm and the incidence of anthracnose and stem-end rot diseases reduced by 75.2% and 80.2%, respectively. The activities of peroxidase, polyphenol oxidase, phenylalanine ammonia-lyase and glucanase had transiently increased in hexanal vapor treated banana by 5 to 7 days and declined thereafter. Postharvest treatment of banana with hexanal vapor resulted in phospholipase D inhibition and also resulted in cell wall thickening of the treated fruit, which impeded the penetration of the pathogenic spores. This was further confirmed by scanning electron micrographs. The defense-related protein intermediaries had increased in hexanal vapor treated banana fruit, which suggests induced resistance against C. gloeosporioides and L. theobromae, via., the phenylpropanoid pathway which plays a significant role in hindering the pathogen quiescence. Delayed ripening due to inhibition of phospholipase D enzyme, inhibition of mycelial growth and induced systemic resistance by defense enzymes collectively contributed to the postharvest disease reduction and extended shelf life of fruit.

  • Pine wood nematode, Bursaphelenchus xylophilus, causes pine wilt disease in a number of Pinus species, which is one of the most serious plant diseases in forest, Korea. In the course of a search for nematicidal substances from endophytic fungi, Fusarium oxysporum EF119 out of the 23 fungal strains tested showed the strongest activity to B. xylophilus. Two nematicidal substances were isolated and identified as bikaverin and fusaric acid. Fusaric acid showed somewhat higher nematicidal activity against B. xylophilus than bikaverin; fusaric acid and bikaverin, at $100{\mu}g/ml$, killed B. xylophilus with mortality values of 50% and 43%, respectively. In addition, both compounds acted synergistically. This is the first report on the nematicidal activity of bikaverin and fusaric acid.

  • A monoterpenoid benzylideneacetone (BZA) is a bacterial metabolite isolated from culture broth of an entomopathogenic bacterium, Xenorhabdus nematophila K1. It was tested in this study the control efficacy of the metabolite against two major fungal diseases occurring in red-pepper plants. BZA exhibited significant antifungal activities against Phytophthora capsici and Colletotrichum acutatum. Under natural light conditions, the antifungal activity of BZA was maintained for more than sixty days. The antifungal activity of BZA was not lost even in soil because the incidence of Phytophthora blight against red-pepper plants was significantly reduced when the suspensions of P. capsici were poured to the rhizosphere soils mixed with BZA. Application of the BZA suspension spray to the fruit surface infected with C. acutatum significantly suppressed the disease occurrence of anthracnose on the red-pepper plants. These results suggest that BZA can be used to develop a promising agrochemical to control phytophthora blight and anthracnose of redpepper plants.

  • Faba bean (Vicia faba L.) is one of the most important legume crops in Egypt. However, production of faba bean is affected by several diseases including fungal diseases. Fusarium wilt incited by Fusarium oxysporum Schlecht. was shown to be the most common wilt disease of faba bean in Assiut Governorate. Evaluation of 16 faba bean genotypes for the resistance to Fusarium wilt was carried out under greenhouse conditions. Three molecular marker systems (inter-simple sequence repeat [ISSR], sequence related amplified polymorphism [SRAP], and simple sequence repeat [SSR]) and a biochemical marker (protein profiles) were used to study the genetic diversity and detect molecular and biochemical markers associated with Fusarium wilt resistance in the tested genotypes. The results showed that certain genotypes of faba bean were resistant to Fusarium wilt, while most of the genotypes were highly susceptible. The percentage of disease severity ranged from 32.83% in Assiut-215 to 64.17% in Misr-3. The genotypes Assiut-215, Roomy-3, Marut-2, and Giza2 were the most resistant, and the genotypes Misr-3, Misr-1, Assiut-143, Giza-40, and Roomy-80 performed as highly susceptible. The genotypes Assiut-215 and Roomy-3 were considered as promising sources of the resistance to Fusarium wilt. SRAP markers showed higher polymorphism (82.53%) compared with SSR (76.85%), ISSR markers (62.24%), and protein profile (31.82%). Specific molecular and biochemical markers associated with Fusarium wilt resistance were identified. The dendrogram based on combined data of molecular and biochemical markers grouped the 16 faba bean genotypes into three clusters. Cluster I included resistant genotypes, cluster II comprised all moderate genotypes and cluster III contained highly susceptible genotypes.

  • Coccidioidomycosis is a rare systemic fungal infection in Korea. However, the incidence of coccidioidomycosis has recently begun to increase due to the increasing incidence of people traveling overseas to endemic areas. In previously reported cases of coccidioidomycosis in Korea, the radiographic findings usually showed a solitary pulmonary nodule, pleural effusion, cavitation, and hilar lymphadenopathy, but no miliary nodules. We report a case of disseminated coccidioidomycosis with miliary nodules in an immunocompetent patient. A 32 year old male, who had traveled in Corona, New Mexico, USA, was admitted for an evaluation of persistent cough with fever. Chest radiography revealed initially diffuse multiple small nodules that appeared to be miliary tuberculosis. However, a subsequent evaluation revealed that he had disseminated coccidioidomycosis.

  • Adenocarcinoma presenting as a solitary mass with a cavity in chest computed tomogram is rare. A few reports have suggested an association between lung cancer and emphysema. We report a case of adenocarcinoma surrounding pulmonary emphysema that mimicked fungal pneumonia. This case highlights the need for cliniclians to be aware of the potential development of lung cancer in patients with emphysema.

  • We report a case of invasive pulmonary aspergillosis invading the mediastinum and the left atrium. A 70-year-old woman was hospitalized for dyspnea. She had been well controlled for her diabetes mellitus and hypertension. The chest X-ray disclosed mediastinal widening, and the computed tomography scan of the chest showed that there was a large mediastinal mass and this lesion extended into the left atrium and right bronchus. The cardiac echocardiography showed that a huge mediastinal cystic mass compressed in the right atrium and a hyperechoic polypoid lesion in the left. The pathology from the bronchoscopic biopsy observed abundant fungal hyphae which was stained with periodic acid-Schiff and Gomori's methenamine silver. Despite the treatment with antifungal agents, she died from cardiac tamponade after three months. Invasive pulmonary aspergillosis, which involves the mediastinum and the heart, is very rare in immunocompetent patients.

  • Acute transverse myelitis(ATM) is defined as an acute intramedullary dysfunction of the spinal cord, ascendng or static involving both halves of the cord and appearing without any history of previous neurological diseases due to traumatic accident, tumor of all kind, encephalitis and of course excluding all possible viral, bacterial and fungal infection. It is mainly characterized by acute motor disorder of both limbs in respect to which spinal segments are affected as well as sensory disorder and dysuria & dyschezia. The exact cause is unknown, however it is recently suggested that immunological factors are highly involved. It has been reported by several reliable sources that it is often accompanied by immunological diseases such as systemic lupus erythematosus(SLE). As treatments non steroid anti-inflammatory drugs(NSAIDS) are primarily recommended as to steroids, limited doses are injected only with the proper prescription from the physician. Operative methods are not options as traumatic accidents and tumors are excluded as factors. To enhance muscle strength and prevent articular contracture physical therapy and passive exercise is imperative. The following patient whose chief complaints were mainly about hypoesthesia of Rt. lower limb and stiffness of phalanges of both fingers as well as to weakness of lower extermity. Therefore it has been diagnosed as arthalgia syndrome. In oriental medicine factors such as wind evil heat-evil, dampness-heat evil, cold evil cause the arthalgia syndrome. In this case the patient was diagnosed as dampness-heat evil and herbal medicine Chunglijagam-Tang and Dong-Qi acupuncture was applied to treat bladder disorder.
