RESUMO
Keloids are the result of an abnormal wound-healing process and are associated with various risk factors. The majority of diagnoses are clinical. Successful treatment of keloid is challenging due to its nonregressing and recurring nature. Case presentation: We discuss the case of a 30-year-old mongoloid male who had multiple swellings over his body for the past 10 years. More striking are the giant keloids that are present over his bilateral scapulae. Diagnosis of keloid was made clinically. Smaller sessile lesions over his shoulder and upper limbs were subjected to intralesional 5-fluorouracil and triamcinolone injections, whereas the giant bilateral scapular keloids underwent excision and split skin grafting. Clinical discussion: Keloids usually present with firm and rubbery masses that extend beyond the site of the previous wound/injury. Keloids are diagnosed and evaluated clinically. Its differentiation from the hypertrophic scar is done based on the presence of multiple lesions beyond the site of the previous wound/injury. Conclusion: Treatment of keloids is difficult due to their nonregressing and recurring nature. Hence, the main goal of treatment is to tailor the therapy to the patient's needs such that the benefits outweigh the risks.
RESUMO
A Gram-stain-positive, aerobic, and non-spore-forming bacterial strain, 20TX0166T, was isolated from a diseased onion bulb in Texas, USA. Upon testing its pathogenicity on onion bulb, it produced pathogenic response which makes it first species of pathogen belonging to the phylum actinobacteria detected in onion. Phylogenetic analysis of the 16S rRNA gene sequence revealed that the strain belonged to the genus Curtobacterium and was most similar to Curtobacterium flaccumfaciens LMG 3645T (100%), C. pusillum DSM 20527T (99.5%), and C. oceanosedimentum ATCC 31317T (99.5%). The estimated genome size of the novel species was 4.0 Mbp with a G + C content of 70.8%. The orthologous ANI (orthoANIu), ANI based on blast (ANIb), and dDDH values between the novel strain and the closest relative, C. flaccumfaciens LMG 3645T, were 95.7%, 95.4%, and 63.3%, respectively. These values were below the recommended species cut-off threshold of 96% (ANI) and 70% (dDDH), suggesting the strain may be a novel species. Physiologic and phenotypic characters of this novel strain were also unique when compared with the closely related species. The major cellular fatty acids of this strain were anteiso-C15:0 and anteiso-C17:0. Using a polyphasic approach based on phenotypic and genotypic analyses, strain 20TX0166T represents a novel species of the genus Curtobacterium, and the name Curtobacterium allii sp. nov. is proposed. The type strain is 20TX0166T (= LMG 32517T = CIP112023T = NCIMB 15427T).

Introduction and importance: Hernias containing appendix, caecum and transverse colon are uncommon in contrast with usual inguinal hernias containing small intestine. The patient usually presents with inguinoscrotal swelling. Case presentation: We present a case of a 2 months old male child presented with inguinoscrotal swelling, vomiting with abdominal distention. On Ultrasonography (USG) of the scrotum, protrusion of the abdominal cavity contents through the right inguinal canal into the scrotum of approximately 3.4 cm × 0.7 cm was found which indicates right inguinal hernia. On the opening of the hernia sac during surgical management, the appendix, caecum and transverse colon were lying inside the hernia sac. Open Herniotomy was performed and the abdomen was closed in layers. Postoperative period of the patient was uneventful. Discussion: Congenital inguinal hernia in the child occurs mostly due to persistent processus vaginalis. History and clinical examination reveals the appearance of lump in the inguinal region or scrotum. Preoperative Ultrasonography can be used to supplement the physical examination and increase the accuracy of its diagnosis. Although the laparoscopic approach is increasingly used nowadays, open hernia repair is preferred in young children. Conclusion: Appendix, caecum and transverse colon are unusual contents of an inguinal hernia. Open herniotomy combined with relieving of the intestinal obstruction is the treatment of choice in young children.

INTRODUCTION AND IMPORTANCE: Adrenal Leiomyomas are infrequent tumors with only a few cases reported to date. They are difficult to differentiate from malignant adrenal tumors due to non-specific findings on clinical examination and imaging studies. CASE PRESENTATION: We discuss the case of a 49-year old male who had been experiencing generalized abdominal pain for 14 months and was found to have a mass on ultrasonography. Further evaluation with Contrast-enhanced Computerized Tomography (CECT) revealed an uneven soft tissue density mass in the retroperitoneal region of the left side. The histopathological examination of the excised mass was suggestive of a mesenchymal tumor, which was further confirmed as leiomyoma by immunohistochemistry. CLINICAL DISCUSSION: Adrenal Leiomyomas are rare smooth muscle tumors that present with heterogeneously enhancing mass on radiologic imaging. On histopathological examination, spindle cells arranged in lobules and fascicles can be appreciated. Positive staining for desmin and smooth muscle actin in immunohistochemistry confirms the diagnosis. CONCLUSION: Identification of the type of tumor in any adrenal mass is challenging pertaining to the non-specific findings on imaging studies. So, prompt surgical resection is the mainstay of the treatment.
RESUMO
INTRODUCTION AND IMPORTANCE: Adrenal schwannomas are extremely rare tumors often misdiagnosed. The patients are usually asymptomatic while some present with non-specific abdominal pain. Only a few cases are reported to date. CASE PRESENTATION: We here present a case of a 55-year-old Nepalese man presented with nonspecific abdominal pain at our Outpatient Department (OPD) found to have mass on ultrasonography of abdomen. On further investigation with Contrast Enhanced Computerized Tomography (CECT) of the abdomen and pelvis, a well-defined heterogeneous adrenal mass of size (7.8 ∗ 8.3 ∗ 6) cm with foci of calcification was seen in the left retroperitoneum. The intraoperative finding of adrenal mass and histopathology of resected mass was suggestive of schwannoma arising from the adrenal gland which was further confirmed by immunohistochemistry. CLINICAL DISCUSSION: Adrenal schwannoma can mimic tumors like pheochromocytoma, adrenal adenoma, cortical carcinoma, neuroblastoma, and other masses. Only 1-3% of schwannomas are retroperitoneal. Radiological findings of this tumor are non-suggestive. The histological section shows spindle cells with Antoni A and Antoni B regions while positive staining of S-100 protein in Immunohistochemistry. CONCLUSION: The diagnosis of adrenal schwannoma in the retroperitoneum is often challenging. The treatment of choice is surgical resection with a good prognosis.
RESUMO
An unusual fluorescent pseudomonad was isolated from tomato exhibiting leaf spot symptoms similar to bacterial speck. Strains were fluorescent, oxidase- and arginine-dihydrolase-negative, elicited a hypersensitive reaction on tobacco and produced a soft rot on potato slices. However, the strains produced an unusual yellow, mucoid growth on media containing 5â% sucrose that is not typical of levan. Based on multilocus sequence analysis using 16S rRNA, gap1, gltA, gyrB and rpoD, these strains formed a distinct phylogenetic group in the genus Pseudomonas and were most closely related to Pseudomonas viridiflava within the Pseudomonassyringae complex. Whole-genome comparisons, using average nucleotide identity based on blast, of representative strain GEV388T and publicly available genomes representing the genus Pseudomonas revealed phylogroup 7 P. viridiflava strain UASW0038 and P. viridiflava type strain ICMP 2848T as the closest relatives with 86.59 and 86.56â% nucleotide identity, respectively. In silico DNA-DNA hybridization using the genome-to-genome distance calculation method estimated 31.1â% DNA relatedness between GEV388T and P. viridiflava ATCC 13223T, strongly suggesting the strains are representatives of different species. These results together with Biolog GEN III tests, fatty acid methyl ester profiles and phylogenetic analysis using 16S rRNA and multiple housekeeping gene sequences demonstrated that this group represents a novel species member of the genus Pseudomonas. The name Pseudomonas floridensis sp. nov. is proposed with GEV388T (=LMG 30013T=ATCC TSD-90T) as the type strain.

Bacterial spot disease of pepper and tomato is caused by four distinct Xanthomonas species and is a severely limiting factor on fruit yield in these crops. The genetic diversity and the type III effector repertoires of a large sampling of field strains for this disease have yet to be explored on a genomic scale, limiting our understanding of pathogen evolution in an agricultural setting. Genomes of 67 Xanthomonas euvesicatoria (Xe), Xanthomonas perforans (Xp), and Xanthomonas gardneri (Xg) strains isolated from diseased pepper and tomato fields in the southeastern and midwestern United States were sequenced in order to determine the genetic diversity in field strains. Type III effector repertoires were computationally predicted for each strain, and multiple methods of constructing phylogenies were employed to understand better the genetic relationship of strains in the collection. A division in the Xp population was detected based on core genome phylogeny, supporting a model whereby the host-range expansion of Xp field strains on pepper is due, in part, to a loss of the effector AvrBsT. Xp-host compatibility was further studied with the observation that a double deletion of AvrBsT and XopQ allows a host range expansion for Nicotiana benthamiana. Extensive sampling of field strains and an improved understanding of effector content will aid in efforts to design disease resistance strategies targeted against highly conserved core effectors.
