RESUMO

Spindle cell soft tissue sarcomas are rare and challenging malignancies that tend to masquerade as benign conditions. This case report presents a 70-year-old female who sought medical attention due to persistent right lower limb pain and swelling over one year. Despite prior consultations at private clinics, her symptoms continued to progress. A tender, palpable swelling was noted upon examination, prompting further diagnostic investigations. Initial X-ray results yielded inconclusive findings, necessitating an MRI study with contrast. The MRI unveiled a substantial multi-lobulated spindle-shaped mass lesion exhibiting heterogeneous enhancement and altered signal intensity, measuring 7.3 x 2.5 x 2.2 centimeters. Additional nodular lesions in the periarticular region posterior to the ankle joint confirmed the diagnostic suspicion of spindle cell sarcoma, supported by orthopedic evaluation. Symptomatic management was initiated with analgesics and antibiotics, alongside a recommendation for biopsy. Histopathological examination of the biopsy specimen confirmed the presence of spindle cell soft tissue sarcoma under high magnification. This case underscores the diagnostic challenges of spindle cell sarcomas and the imperative role of a multidisciplinary approach in their accurate diagnosis and management.

RESUMO

Obstructive uropathy, a prevalent clinical problem, can irreparably harm the kidneys if not treated promptly. As a result, accurate diagnosis is necessary for prompt management. This study examines the utility of multidetector computed tomography (MDCT) urography in identifying obstructive uropathy. PubMed, Google, Embase, Medline, and other electronic databases were used to search the English-language literature. The search phrases were obstructive urinary infections or urinary bladder or kidneys or MDCT. The authors' expertise and experience in the subject area aided in archiving pertinent publications. Even though the dilated upper tract of the ureters can be seen, ultrasonography (USG) has limitations because it cannot show the middle portion of the ureters, even if they are dilated mostly due to bowel gas artifacts. The USG does not emphasize the functioning of the renal tract. To evaluate obstructive uropathy, MDCT urography plays a very important role. For speedy, effective therapy, it provides a quick diagnosis of the source of obstruction.

RESUMO

Tuberous sclerosis (TS) is a potentially severe medical disorder that poses a life-threatening risk and can lead to drastic lifestyle changes. In infants and young children, the typical diagnostic criteria for this condition encompass cutaneous manifestations and seizures, and the development of cellular growths termed hamartomas, astrocytomas, myolipomas, and even carcinomas observed within the cardiac, cerebral, renal, and retinal tissues. The usual age of presentation varies widely, which affects the prognosis. We report a case of a four-month-old male patient who presented with early signs of TS. The patient showed signs of infantile spasms and seizures. On further examination, he had neurological, cutaneous, cardiac, and retinal manifestations, which pointed toward the diagnosis of TS. This case report emphasizes the importance of screening for TS at an early age due to the possibility of patients presenting earlier than the usual age of presentation. To the best of our knowledge, there is scarce data on this kind of early-onset signs of TS; therefore, we feel that it is imperative to start screening infants earlier to improve the prognosis and decrease the complications of this disease. The screening tests and the incidence of screening will vary based on the cost and availability of proper diagnostic and screening tests and the accessibility of efficient treatments.

RESUMO

When it comes to thyroid disorders, Graves' disease (GD) is the most prevalent autoimmune thyroid disorder in which antibodies are formed against thyroid receptors. Myasthenia gravis (MG) is a rare autoimmune neuromuscular junction disorder. Autoimmune antibodies are formed against postsynaptic neuromuscular junctions in MG, interrupting neuromuscular transmission and causing variable muscle weakness and tiredness. It affects older men and young women. The two disorders may coexist in a patient, or either of them may develop first. The thyroid condition GD is most frequently linked to MG. This case report describes an older man who presented with an acute exacerbation of MG along with a thyrotoxic crisis.

RESUMO

Ultrasound is the modality of choice for detecting the causes of acute scrotal pain and diagnosing scrotal pathologies. Pyocele is a term used for describing the purulent fluid collection in the scrotal sac, which may present to the hospital as a complication of testicular abscess, epididymal-orchitis, or post-trauma. Ultrasound is the modality of choice for diagnosing such pathologies. The presented case is of a young male from rural India who developed a pyocele post-trauma and underwent an ultrasound examination, where it was found to be a ruptured pyocele with contents spreading into the hemi-scrotum. Rupture of the tunica is frequently associated with the hematocele; however, pyocele is less commonly associated with rupture. The case report discusses the causes of pyocele, imaging features, management, and complications of this pathology along with other possible differential diagnosis.

RESUMO

Patients present to the orthopedic outpatient department with complaints of shoulder pain on movement or restriction of movement in the shoulder joint and are referred for magnetic resonance imaging (MRI) of the shoulder joint. Almost all the patients have similar complaints but may have a wide range of pathology affecting the joint and causing pain. Rotator cuff tears or tendinopathy are the most common causes of shoulder pain. Ultrasound (USG) and MRI are the most commonly used imaging modalities for assessing rotator cuff pathologies. There is a wide range of pathologies affecting the shoulder joint, other than rotator cuff tendinopathies or tears, for which USG is less sensitive and specific in detecting accurate pathology. MRI is the choice of imaging for shoulder joint pathologies. We present a pictorial review discussing and depicting MRI features of a wide list of pathologies of the shoulder joint complex that should be kept in mind when the patient presents with shoulder pain.

RESUMO

Fibroids, also known as uterine leiomyomas, are the most common solid benign lesions of the uterus. Fibroids are responsive to hormones and are stimulated by estrogens and commonly grow during pregnancy and involute as menopause progresses. The treatment is mostly conservative. When symptomatic, the treatment requires surgical intervention. We present a case of a 72-year-old post-menopausal female with a large, calcified parasitic fibroid, an extremely rare variant of uterine leiomyoma occurring outside the uterus. The number of cases reported about this pathology is minimal.

RESUMO

Degeneration of the lumbar intervertebral disc is the most common cause of lower back pain. It is directly related to daily activities, mechanical stress, and other biological factors. We use imaging modalities to assess the degree of disc degeneration, out of which magnetic resonance imaging (MRI) is the most popular non-invasive modality. It is believed that early changes in disc degeneration are due to the biochemical events in the disc and can be evaluated by sequences in MRI involving the diffusion of water molecules. The apparent diffusion coefficient (ADC) is one such sequence that captures the signals based on the diffusion of water molecules. Ten articles were chosen from PubMed and Google Scholar using the MeSH terms 'lumbar spine degeneration' and 'apparent diffusion coefficient'. This review article has summarized various studies intending to gain a better understanding of the biochemical events leading to the development of disc degeneration. This study has also gathered the role of various sequences in MRI that can quantitatively assess disc degeneration.

RESUMO

BACKGROUND: Anaerobic Gram-negative bacteria (AGNB) play a significant role as both pathogens and essential members of the human microbiota. Despite their clinical importance, there remains limited understanding regarding their antimicrobial resistance (AMR) patterns. This knowledge gap poses challenges in effectively managing AGNB-associated infections, as empirical treatment approaches may not adequately address the evolving resistance landscape. To bridge this research gap, we conducted a comprehensive study aimed at exploring the role of human AGNB as a reservoir of AMR. This can provide valuable insights for the prevention and management of anaerobic infections. METHODS: We studied the prevalence of AMR and AMR determinants conferring resistance to metronidazole (nimE), imipenem (cfiA), piperacillin-tazobactam (cepA), cefoxitin (cfxA), clindamycin (ermF), chloramphenicol (cat) and mobile genetic elements (MGEs) such as cfiAIS and IS1186 associated with the cfiA and nim gene expression. These parameters were studied in Bacteroides spp., Fusobacterium spp., Prevotella spp., Veillonella spp., Sutterella spp., and other clinical AGNB. RESULTS: Resistance to metronidazole, clindamycin, imipenem, piperacillin-tazobactam, cefoxitin and chloramphenicol was 29%, 33.5%, 0.5%, 27.5%, 26.5% and 0%, respectively. The presence of resistance genes, viz., nim, ermF, cfiA, cepA, cfxA, was detected in 24%, 33.5%, 10%, 9.5%, 21.5% isolates, respectively. None of the tested isolates showed the presence of a cat gene and MGEs, viz., cfiAIS and IS1186. The highest resistance to all antimicrobial agents was exhibited by Bacteroides spp. The association between resistant phenotypes and genotypes was complete in clindamycin, as all clindamycin-resistant isolates showed the presence of ermF gene, and none of the susceptible strains harbored this gene; similarly, all isolates were chloramphenicol-susceptible and also lacked the cat gene, whereas the association was low among imipenem and piperacillin-tazobactam. Metronidazole and imipenem resistance was seen to be dependent on insertion sequences for the expression of AMR genes. A constrained co-existence of cepA and cfiA gene in B. fragilis species was seen. Based on the absence and presence of the cfiA gene, we divided B. fragilis into two categories, Division I (72.6%) and Division II (27.3%), respectively. CONCLUSION: AGNB acts as a reservoir of specific AMR genes, which may pose a threat to other anaerobes due to functional compatibility and acquisition of these genes. Thus, AST-complying standard guidelines must be performed periodically to monitor the local and institutional susceptibility trends, and rational therapeutic strategies must be adopted to direct empirical management.

RESUMO

The study was conceived with the hypothesis that human aerobic gut flora could act as a reservoir of ß-lactamases and contribute to the emergence of ß-lactam resistance by transferring ß-lactamase genes to resident anaerobes. Thus, we studied the repertoire of ß-lactam resistance determinants (ß-lactamases associated with aerobes and anaerobes) in Gram-negative anaerobes. The phenotypic resistance against ß-lactams and the presence of aerobic and anaerobic ß-lactamases were tested in Gram-negative anaerobic isolates (n = 200) by agar dilution method and targeted PCR, respectively. In addition, whole-genome sequencing (WGS) was used to study the ß-lactam resistance determinants in 4/200 multi-drug resistant (MDR) strains. The resistance to ß-lactams was as follows: imipenem (0.5%), cefoxitin (26.5%), and piperacillin-tazobactam (27.5%). None of the isolates showed the presence of ß-lactamases found in aerobic microorganisms. The presence of anaerobic ß-lactamase genes viz. cfiA, cepA, cfxA, cfiAIS [the intact segment containing cfiA gene (350 bp) and upstream IS elements (1.6-1.7 kb)] was detected in 10%, 9.5%, 21.5%, and 0% isolates, respectively. The WGS data showed the presence of cfiA, cfiA4, cfxA, cfxA2, cfxA3, cfxA4, cfxA5 in MDR strains. The study showed a distinct dichotomy in repertoires of ß-lactamases between aerobes and anaerobes.

RESUMO

Astrocytomas are rare in adults and less common in the parietal and temporal regions of the brain parenchyma. The current case is of a 26-year-old female patient who presented with a four-month history of headaches and a two-month history of vomiting. The patient's MRI brain showed an ill-defined, thick-walled lesion in the right parietal and temporal region with mass effect, which on histopathology confirmed to be a case of WHO Grade 1 astrocytoma. This manuscript describes the imaging and histopathological appearance of WHO Grade 1 astrocytoma in an adult female.

RESUMO

Internal jugular vein (IJV) thrombosis, also known as Lemierre syndrome (LS), is a potentially dangerous complication that follows oropharyngeal infections. It has also been documented in individuals with cervical lymph node infection, thyroid abscess, and pharyngeal abscess. LS is potentially a catastrophic complication and, if not detected and treated early, can lead to mortality. This case report describes an older woman who presented with a history of fever, odynophagia, and swelling in the anterior aspect of her neck for 20 days. Examination revealed a severely congested posterior pharyngeal wall with bilateral tonsillitis and a tender goiter. Further investigations revealed a diagnosis of LS. The patient was appropriately managed with higher antibiotics and anticoagulation. This case report highlights the importance of IJV thrombosis, which can present as a thyroid swelling.

RESUMO

A complex of anomalies involving the vertebral column and spinal canal (V), anal atresia(A), congenital lesions of the heart (C), defects involving the trachea esophageal complex (TE), renal system, and urinary tract (R), and limb lesions (L) is known as VACTERL complex. VACTERL is an umbrella term for patients with abnormalities involving three or more of the systems mentioned above. It can be potentially life-threatening and should be promptly recognized and managed. Thorough investigations are required to prevent long-term sequelae and to improve morbidity. We present a case of a neonate born to a mother with twin gestation at 38 weeks of gestation with antenatally diagnosed severe polyhydramnios and a single umbilical artery and vein. This manuscript discusses the imaging findings of the congenital abnormalities involving the cardiac and skeletal system with tracheoesophageal fistula in our patient.

RESUMO

Bacteroides nordii, is an understudied member of the pathogenic B. fragilis group which comprises several multidrug-resistant (MDR) strains. Thus, it is of great interest to study the genome biology of Bacteroides nordii. However, no detailed study is available that characterized B. nordii at the genetic level and explored its role as a potential pathogen. We isolated an MDR strain viz., B. nordii PGMM4098 from the pus sample and subjected it to whole genome sequencing using Illumina technology. The draft genome was de-novo assembled and annotated, followed by comprehensive comparative genomics analyses using the publicly available genome dataset of B. nordii. The pan-genome analysis revealed the open nature of B. nordii, indicating the continuous accumulation of novel genes in non-core components leading to the emergence of new strains of this species. The thirteen antimicrobial resistance (AMR) genes identified in the genomes of all B. nordii strains were part of the non-core component of the pan-genome. Of these, four AMR genes, nimE, aadS, mef(En2), and ermB/F/G were found to be acquired via the process of horizontal gene transfer (HGT) from anaerobic Bacteroidetes. Importantly, the nimE gene conferring metronidazole resistance was found to be present only in B. nordii PGMM4098, which harbors five other AMR genes encoded in its genome. Of these, nimE (metronidazole resistance), ermB/F/G (macrolide-lincosamide-streptogramin B resistance), and cfxA2/A3 (class A ß-lactam resistance) genes were further validated using targeted polymerase chain reaction assay. Notably, these three genes were also found to be under the operation of positive selective pressure suggesting the diversification of these genes, which might lead to the emergence of new MDR strains of B. nordii in the near future. Our study reported and characterized the genome of the first MDR strain of B. nordii and revealed the AMR evolution in this species using a comprehensive comparative genomics approach.

RESUMO

To date, antimicrobial susceptibility testing (AST) in anaerobes is highly disarrayed. The testing is not routinely performed in many laboratories to direct appropriate antimicrobial therapy, and literature on AST remains scarce. This review aims to present the current methods employed for the AST of anaerobic bacteria both in routine and research. Anaerobes are potential human pathogens and predominate the human microbiota. Despite their significant role in human health and disease, they are not paid enough heed. The educated experience-based treatment has often been instituted with anaerobic infections due to the challenging AST and relatively predictable patterns of antimicrobial resistance (AMR). However, the AMR in anaerobes remains no more predictable, especially in Gram-negative anaerobes like Bacteroides spp., where multi-drug resistance is also emerging. The changing antibiograms and the emergence of resistance determinants in anaerobes necessitate routine AST, periodic monitoring, and literature review of these organisms. The present scenario dictates to limit the empirical management of anaerobic infections and encourage consistent AST practice in routine by employing economical, faster, and more pragmatic approaches, especially in tertiary care setups that cater to a vast patient population and are held accountable for producing accurate clinical and surveillance data. The article may provide a broad perspective on the topic and different AST solutions.

RESUMO

Radial Ray Defect (RRD) is a rare disorder, and the etiology of this disorder is still under discussion. RRD is associated with many medical conditions for which prenatal counselling is of paramount importance. Any association with the family history is still unknown. The patient is a 16-year-old female who came to the orthopaedic clinic complaining of tingling and weakness in the right forearm. On examination, there was a gross deformity in the right forearm with radial deviation of the hand. An X-ray revealed radial ray defect type-2. She previously had a history of perinatal infection during early childhood. Surgery was successfully achieved, and positive results were accomplished. Radial Ray Defect can be focal or associated with other clinical manifestations. The timing of antenatal ultrasound for detecting this musculoskeletal anomaly is crucial. When RRD is associated with other syndromes, counselling to the parents about the quality of life and morbidity comes into play. Treatment is primarily surgical.

RESUMO

OBJECTIVE: To study the spectrum of anaerobic infections and the frequency of clinically relevant anaerobes in various infections in a tertiary care hospital in North India. METHOD: In this two-year (2018-2019) retrospective study, a total of 22,177 samples were processed both anaerobically and aerobically. The samples included blood, pus, body fluids, necrotic tissues, abscess, peritoneal fluids, and other specimens of conditions predisposing to anaerobic infections. The recovered bacterial isolates were identified by matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS). RESULT: Of the 22,177 samples processed anaerobically, 1094 showed significant anaerobic growth yielding 1464 anaerobes. Bacteroides fragilis (12.7%) and Peptoniphilus harei (12.2%) were the most predominant anaerobes, whereas Escherichia coli (32.6%) and Staphylococcus aureus (13.2%) were the most frequently recovered facultative anaerobes in polymicrobial growth. Both aerobic and anaerobic data were available for 673/1094 samples, of which 68% represented a polymicrobial etiology and 32% as monomicrobial. Of the cases where complete clinical information was available (504/1094), the majority of the anaerobes were recovered from the skin and soft tissue infections (36.3%) and intra-abdominal infections (17.1%). The clinical specimen most frequently growing anaerobes was abscess (29.1%), followed by diabetic foot ulcers (14.1%). CONCLUSION: The study documents the frequency of clinically significant anaerobic bacteria in various infections, and their associations with aerobes in polymicrobial growth. The present study may aid us in devising better therapeutic strategies against both aerobes and anaerobes in anaerobic infections, which is often empirical. Besides, the data can update clinicians with the changing patterns of anaerobic infections, which remains a neglected concern.
