Miliary Tuberculosis: an Accidental Finding at Autopsy

Background: Forensic pathologists often encounter various disease conditions at autopsy which would not have been diagnosed ante-mortem and they often explain poor clinical outcomes in some patient.Case Report: The following is a case report of a 55-years old female who died of complications of degloving injury to the right lower limb.Conclusion: Miliary Tuberculosis was an accidental finding at autopsy and thus explained the deteriorating condition of patient and failure to respond to the treatment

Dispersion from C^alpha or N^H: 4D experiments for backbone resonance assignment of intrinsically disordered proteins

N-HSQC spectrum. Application of these 4D experiments is demonstrated using BilRI (165 aa), an outer-membrane intrinsically disordered protein from the opportunistic oral pathogen Aggregatibacter actinomycetemcomitans. BilRI amino acid sequence encompasses three very similar repeats with a 13-residue identical stretch in two of them

Arabidopsis RCD1 coordinates chloroplast and mitochondrial functions through interaction with ANAC transcription factors

Reactive oxygen species (ROS)-dependent signaling pathways from chloroplasts and mitochondria merge at the nuclear protein RADICAL-INDUCED CELL DEATH1 (RCD1). RCD1 interacts in vivo and suppresses the activity of the transcription factors ANAC013 and ANAC017, which mediate a ROS-related retrograde signal originating from mitochondrial complex III. Inactivation of RCD1 leads to increased expression of mitochondrial dysfunction stimulon (MDS) genes regulated by ANAC013 and ANAC017. Accumulating MDS gene products, including alternative oxidases (AOXs), affect redox status of the chloroplasts, leading to changes in chloroplast ROS processing and increased protection of photosynthetic apparatus. ROS alter the abundance, thiol redox state and oligomerization of the RCD1 protein in vivo, providing feedback control on its function. RCD1-dependent regulation is linked to chloroplast signaling by 3'-phosphoadenosine 5'-phosphate (PAP). Thus, RCD1 integrates organellar signaling from chloroplasts and mitochondria to establish transcriptional control over the metabolic processes in both organelles.Peer reviewe

Uncommon manifestations of Endocervical Malignant Mixed Mullerian Tumor with Incidental Bilateral Fallopian Tube Carcinoma

A 43-year-old perimenopausal lady presented with bleeding per vagina and lower abdominal pain. On evaluation, she had cervical polyp, which expelled spontaneously during the per speculum examination. Histopathology revealed malignant mixed Mullerian tumor. Extended hysterectomy with salphingo oophorectomy was carried out, which showed bilateral fallopian tube carcinoma and leiomyoma uterus. The patient was treated with carboplatin regime and found to be disease-free for 1 year. This case presented because of a rare combination of the lesions

Filariasis in body fluids: Report of three cases

Filariasis is disabling parasitic disease which is prevalent worldwide and caused by various species of filarial organism. Wuchereria bancrofti (W. Bancrofti) is responsible for 90% of cases of filariasis and is found throughout the tropics and in some sub-tropical areas. Cytology has an important role in the diagnosis of subclinical filariasis. Microfilaria is frequently detected in association with neoplasm, although the role in tumorogenesis is controversial. The early detection of the disease could thus mean the difference between a productive healthy life and a lifetime of chronic disability. The identification of microfilaria in body fluids is a rare scenario. We are presenting here with three cases of microfilaria, which was detected in the pleural fluid, bronchoalveolar lavage, pericardial fluid, and in semen with different clinical scenarios. The purpose of this paper was to illustrate these examples and to review the appropriate literature in order to make physicians aware of this uncommon entity

A Rare Case of Fungal Maxillary Sinusitis due to Paecilomyces lilacinus in an Immunocompetent Host, Presenting as a Subcutaneous Swelling

Paecilomyces is a colonizing fungal species which usually causes keratitis, endocarditis, sinusitis, nephritis, fungemia, cutaneous, and subcutaneous infections in immunocompromised host. Very rarely, it causes similar infection in immunocompetent host without any risk factors. We report a case of maxillary sinusitis due to Paecilomyces lilacinus in a 65–year-old immunocompetent male, who presented with a subcutaneous swelling below the left eye. The lesion was excised by surgery and treated with itraconazole for 6 months based on culture and sensitivity. After 1 year of follow up, he is free of symptoms with no evidence of recurrence

Study of histopathological patterns of endometrium in abnormal uterine bleeding

Background: Abnormal uterine bleeding (AUB) is a common gynecological complaint associated with considerable morbidity and significantly affects the patient′s family, personal and social life. The aim of the study was to analyze the histomorphological patterns of endometrium in patients presenting with AUB and also to determine the incidence of AUB in various age groups. Materials and Methods: This is a prospective study, conducted in the Department of Pathology, in a tertiary care teaching hospital, Mangalore from October 2011 till date. All cases of AUB with a probable endometrial cause were included in the study. Data was entered in Microsoft Excel and managed in Statistical Package for the Social Sciences (SPSS) version 16. Analysis was done in the form of percentages and proportions and represented as tables where necessary. Results: A total of 156 cases were analyzed. Patients′ age ranged from 23-78 years. AUB was most prevalent in the perimenopausal age group. The most common presenting complaint was menorrhagia (47%). Endometrial hyperplasia was the most common histopathological finding and was seen in 25% patients, followed by secretory endometrium in 16.7% patients, and proliferative phase pattern and disordered proliferative endometrium were seen in 12.2% patients each. Malignancy was detected in 6.4% of cases and endometrial carcinoma was the most common lesion (4.5%). Conclusions: Histopathological evaluation of endometrial samples is especially indicated in women over the age of 35 years to rule out malignancy and preneoplasia. Among the patients with no organic pathology, normal physiological patterns with proliferative, secretory, and menstrual changes were observed. The most common endometrial pathology in this series was endometrial hyperplasia

Disseminated Cutaneous Rhinosporidiosis

Rhinosporidiosis is a granulomatous disorder caused by Rhinosporidium seeberi. It frequently involves the nasopharynx and occasionally affects the skin. We hereby report a case of 46–year-old male who presented with multiple cutaneous plaque-like lesions with nasal obstruction. On examination, multiple cutaneous lesions were found to be present on malar aspect, infraorbital and supraorbital region, right shoulder and over the back near the tip of scapula. Oral cavity revealed a polypoidal lesion, in the base of the tongue. Excision biopsy confirmed the lesions as disseminated cutaneous rhinosporidiosis. The patient was treated with excision and dapsone therapy. After 1 year of therapy, the patient has disease-free survival. We report this rare case of rhinosporidiosis with disseminated cutaneous involvement

Discovery of varlaxins, new aeruginosin-type inhibitors of human trypsins

Low-molecular weight natural products display vast structural diversity and have played a key role in the development of novel therapeutics. Here we report the discovery of novel members of the aeruginosin family of natural products, which we named varlaxins. The chemical structures of varlaxins 1046A and 1022A were determined using a combination of mass spectrometry, analysis of one- and two-dimensional NMR spectra, and HPLC analysis of Marfey’s derivatives. These analyses revealed that varlaxins 1046A and 1022A are composed of the following moieties: 2-O-methylglyceric acid 3-O-sulfate, isoleucine, 2-carboxy-6-hydroxyoctahydroindole (Choi), and a terminal arginine derivative. Varlaxins 1046A and 1022A differ in the cyclization of this arginine moiety. Interestingly, an unusual α-D-glucopyranose moiety derivatized with two 4-hydroxyphenylacetic acid residues was bound to Choi, a structure not previously reported for other members of the aeruginosin family. We sequenced the complete genome of Nostoc sp. UHCC 0870andidentified the putative 36 kb varlaxin biosynthetic gene cluster. Bioinformatics analysis confirmed that varlaxins belong to the aeruginosin family of natural products. Varlaxins 1046A and 1022A strongly inhibited the three human trypsin isoenzymes with IC50 of 0.62–3.6 nM and 97–230 nM, respectively, including a prometastatic trypsin-3, which is a therapeutically relevant target in several types of cancer. These results substantially broaden the genetic and chemical diversity of the aeruginosin family and provide evidence that the aeruginosin family is a source of strong inhibitors of human serine proteases.peerReviewe
