RESUMEN

In the extra-peritoneal approach for inguinal hernias, pre-peritoneal space creation is one of the most crucial steps. In the absence of well-defined landmarks, it is difficult to identify the correct plane of dissection, and blind dissection can sometimes lead to peritoneal injury, resulting in loss of working space. In this article, we describe our technique of pre-peritoneal space creation by following the fatty tissue of the median umbilical ligament and fatty tissue along the rectus muscle. The data of all patients (total 84) who underwent surgery with this technique between January 2021 and May 2023 were retrieved and assessed for demographics, hernia type, and perioperative complications. Except for two peritoneal injuries, there were no other intraoperative complications.

RESUMEN

Objectives: Phaeohyphomycosis refers to infections caused by phaeoid/dematiaceous or darkly pigmented fungi. This study was undertaken to further increase our knowledge about the incidence of phaeohyphomycosis and its causative agents. Materials and Methods: The present study was conducted over a period of one and a half years (January 2018-June 2019) on specimens received from patients with varied clinical manifestations ranging from superficial infections, subcutaneous cysts, pneumonia, brain abscess to a disseminated infection. These specimens were processed in the Department of Microbiology for potassium hydroxide (KOH) examination and culture and in Pathology for cytology/histopathological examination (HPE). All specimens positive on direct examination for dark grey, brown or black fungi were included in the study. Results: A total of 20 specimens were confirmed as phaeohyphomycosis. Most of the patients belonged to the age group of 41 to 50 years. Male: Female ratio was 2.3:1. Trauma was the most common risk factor. Spectra of the isolated fungal pathogens comprised of Bipolaris species, Exophiala species, Curvularia geniculata, Phialemonium species, Daldinia eschscholtzii, Hypoxylon anthochroum, Phaeoacremonium species, Leptosphaerulina australis, Medicopsis romeroi, Lasiodiplodia theobromae, Eutypella species, Chaetomium globosum, Alternaria species, Cladophialophora bantiana and 2 unidentified dematiaceous fungi. Recovery from phaeohyphomycosis was seen in 12 patients, 7 were lost to follow up and one patient succumbed to the illness. Conclusion: Infections caused by phaeoid fungi can no longer be viewed as rare. In fact, phaeohyphomycosis can have myriad of presentations spanning from mild cutaneous infections to fatal brain disease. Therefore, a high index of clinical suspicion is needed to diagnose such infections. The primary treatment modality remains surgical removal of the lesion in cutaneous or subcutaneous infections however disseminated disease with a guarded prognosis requires aggressive management.

RESUMEN

BACKGROUND: Clostridium sporogenes is reported rarely in literature. Reports from the skin and soft tissue infections are even less, more so in immunocompetent patients. CASE PRESENTATION: Two skin and soft tissue infections with C. sporogenes in immunocompetent patients have been presented in this study. One of the cases was following an electrical burn wound, and the other was following a bedsore. Both patients expired despite antibacterial treatment and debridement. DISCUSSION AND CONCLUSION: C. sporogenes had usually been reported after trauma particularly after penetrating and deep wound infection. More attention should be given to these patients so that the infection can be treated and diagnosed early in suspected anaerobic infections like Clostridium species.

RESUMEN

INTRODUCTION: Fine-needle aspiration cytology (FNAC) forms one of the first-line investigations in the evaluation of tumors in modern era. Its role in diagnosing soft tissue tumors (STT) has been well established. However, the morphological overlap and biological heterogeneity of STT pose a morphological diagnostic challenge. AIMS: To evaluate the scope of FNAC in diagnosis and categorization of STT and to correlate the cytological features with histological findings wherever available, and to analyze the reasons for discordance, if any. MATERIALS AND METHODS: All FNAs of cytologically diagnosed STT during 5-year period were retrospectively analyzed. FNAC smears stained using May-Grünwald Giemsa, Pap- and hematoxylin and eosin, were evaluated and interpreted inconjunction with clinical details. Cellblock and immunocytochemistry (ICC) was done, wherever required to render the final diagnosis. RESULTS: Of the total 15,844 FNAC done in 5 years, 1319 (8.3%) cases were diagnosed as STT. Benign tumors comprised the majority (94.2%), whereas 5.8% were diagnosed to be malignant. These were further grouped according to the cytomorphological features into adipocytic (82.2%), benign spindle cell lesions (10.8%), vascular (1.4%), spindle cell sarcoma/sarcoma NOS (2.2%), myxoid (0.3%), round cell tumors (0.9%), metastatic tumors (1.9%), and others (0.3%). The cytological findings were corelated with histopathological findings, which were available in 316 cases. The specificity and sensitivity calculated for detecting malignancy was 99.2% and 95.4%, respectively. The overall diagnostic accuracy for diagnosing malignancy was 98.7%. Among the group of non-adipocytic tumors, the sensitivity, specificity, PPV, NPV calculated for diagnosing a malignant tumor (irrespective of exact sub-categorization) is 95.2%, 100%, 100%, and 96.4%, respectively. The overall diagnostic accuracy in non-adipocytic tumors is 97.92%. CONCLUSION: FNAC is a simple, cost effective, and minimally invasive method in diagnosing STT with good sensitivity and specificity. It is of utility not only in primary lesions, but also for metastatic tumors, and for the documentation of locally recurrent soft tissue neoplasms.

RESUMEN

Background: Complete mesocolic excision with central vascular ligation for colonic cancers improves overall survival. To achieve better short term and oncological results, different laparoscopic techniques have been described for right-sided colonic cancers. Laparoscopic right hemicolectomy by the Initial Retrocolic Endoscopic Tunnel Approach (IRETA) is proposed to be easy and offer desired oncological resection; we present our results with IRETA. Patients and Methods: The data of all patients who underwent right hemicolectomy by IRETA for colonic cancer between January 2019 and March 2020 were retrospectively analysed for demographics, clinical features, oncological completeness of resected specimen, complications, hospital stay, morbidity and mortality. Results: A total of eight patients (05 males and 03 females) were identified. The mean operating time was 190 ± 32.40 minutes. Margins of all resected specimens were free of tumour except for one in which retro-peritoneal circumferential resection margin was positive. On average 13.75 ± 2.63 lymph nodes were retrieved. Except for wound infection in one patient, no other morbidity was seen. Conclusion: Laparoscopic radical right hemicolectomy by IRETA is safe and gives desired oncological results.

RESUMEN

In India, Apophysomyces species complex is the second common agent of mucormycosis mainly affecting immunocompetent hosts unlike other Mucorales. It is frequently involved in causing necrotizing cutaneous infections. The present two-year study was planned to investigate the causative role of Apophysomyces spp. in cutaneous necrotizing infections. The tissue samples were processed using standard techniques and in five out of 65 patients, Apophysomyces variabilis was the etiological agent. Diabetes mellitus and trauma were common risk factors and despite appropriate treatment only one patient could be survived. Apophysomyces variabilis is emerging as agent of necrotizing infections which invariably result in poor patient outcomes.

RESUMEN

BACKGROUND: Circulating tumor cells (CTCs) are cells present in the blood stream that are antigenically or genetically similar to a specific tumor type and are markers of tumor diagnosis, prognosis, residual disease and metastasis. The ever-increasing burden of breast cancer globally warrants the incorporation of this all-inclusive marker in the diagnostic repertoire using the simplest of techniques. AIMS: To identify CTCs in peripheral blood by cell block (CB) technique in cases of breast cancer diagnosed on fine-needle aspiration (FNA) or core needle biopsy (CNB) and to correlate their presence with nodal metastasis. MATERIAL AND METHODS: This study was conducted in the Department of Pathology, at a tertiary care hospital. Peripheral blood samples from a total of 30 cases of primary breast carcinoma diagnosed on FNA or CNB without prior neoadjuvant chemotherapy were analyzed using the CB technique. RESULTS: The age ranged between 29-74 years with the most common presenting complaint being a palpable, single, unilateral breast lump. CTCs were detected in 2 (6.7%) cases with a <5 cell cluster with both the cases being grade I breast carcinomas and also displaying nodal metastasis.

RESUMEN

BACKGROUND: The use of fine-needle aspiration (FNA) as a primary tool in the diagnosis of breast carcinoma provides opportunity for early proliferative characterization of the tumor. This study was undertaken to assess DNA ploidy and S-phase (SPF) fraction by flow cytometry in fine needle aspirates of patients with breast cancer. METHOD: Fifty patients of breast cancer diagnosed on fine needle aspiration cytology (FNAC) and who subsequently underwent either mastectomy or lumpectomy were included. Material obtained by FNAC was subjected to DNA ploidy and SPF analysis. Immunohistochemical estimation of Ki-67 was done on histopathology sections. The proliferation markers (SPF and Ki-67) were compared with each other and with the histopathologic parameters. RESULTS: On DNA flow cytometry, 27 (54%) cases were aneuploid and 23 (46%) cases were diploid. The median SPF was 12.43% and 4.03% in aneuploid and diploid tumors respectively. Median Ki-67 among aneuploid tumors was 28.6% compared to 8.7% among diploid tumors. Aneuploid tumors were significantly associated with higher values of SPF and Ki-67, with Kappa 0.437 and agreement of 72%. Diploid tumors showed lower values of SPF and Ki-67, with Kappa 0.455 and agreement of 72.7%. Correlation among SPF and Ki-67 was highly significant with Kappa value 0.446, P value of .002 and agreement of 72.3%. CONCLUSION: DNA ploidy and proliferative activity by flow cytometric SPF estimation on fine needle aspirates from breast cancer can provide valuable prognostic and predictive information at the time of diagnosis in patients with breast cancer. This might help in selection of appropriate treatment modality.

RESUMEN

OBJECTIVE: Phaeohyphomycosis caused by phaeoid fungi is a type of mycosis emerging worldwide which causes a wide variety of clinical manifestations. STUDY DESIGN: A retrospective analysis of 11 cases diagnosed with fungal inflammation on cytology over a period of 6 years (2013-2018) was done along with culture/histopathologic confirmation. RESULTS: Of the total of 11 cases, 9 cases presented with subcutaneous swellings and 1 case each with brain and lung lesions. The age range was 30-83 years (mean: 53.6); 8 patients were male and 3 were female. Cytologic smears showed fungal profiles with septate tortuous hyphae, as well as swollen and narrow, yeast-like swellings with an irregular breadth of the hyphae in all cases. The fungal profiles were visualized on a Masson-Fontana stain. The background showed inflammatory cells, giant cells, and necrosis in variable proportions. Five cases were diagnosed as phaeohyphomycosis on cytology, whereas 3 cases were misdiagnosed as aspergillus and 2 as candida. In 1 case, typing of the fungus was not done. Histopathology was available in 5 cases, and in all these a diagnosis of phaeohyphomycosis was reached. Ten of the 11 cases had confirmation on fungal culture. CONCLUSIONS: Phaeoid fungi are rarely seen in routine cytologic practice. Careful evaluation of cytologic smears and an awareness of the characteristic morphologic features of phaeohyphomycosis are helpful in arriving at a correct diagnosis. Fine needle aspiration cytology provides a rapid diagnosis, enabling prompt therapy.

RESUMEN

BACKGROUND: Postoperative pancreatic fistula (POPF) or leak from pancreaticojejunostomy (PJ) is one of the most common complications after pancreaticoduodenectomy (PD), with an incidence of 5%-30%. Various techniques have been advocated to bring down the incidence of POPF, but there is still none that can be called the "gold standard". Peng's binding PJ (BPJ) was proposed as a good method of performing PJ with low fistula rates; we present our results with BPJ. METHODS: The data of all patients who underwent PD with BPJ between January 2016 and March 2018 were retrospectively analyzed for demographics, clinical features, type of procedure performed, complications (especially POPF), hospital stay, morbidity, and mortality. RESULTS: A total of 24 patients (18 males and 6 females) were identified. The mean age at the diagnosis was 65.5 ± 6.4 years. Majority of the patients had ampullary carcinoma (62.5%). The most common postoperative complication was delayed gastric emptying seen in 10 patients, whereas only 2 (8.33%) had POPF and there was one mortality. CONCLUSION: BPJ is safe and is associated with a low incidence of POPF.

RESUMEN

BACKGROUND: Necrotizing soft tissue infections (NSTI) are frequently encountered, with a high mortality despite advances in health care. MATERIAL AND METHODS: Patients presenting with NSTI were prospectively followed up in an attempt to identify factors that were significantly associated with mortality. RESULTS: There were a total of 86 patients [65 males (75.6%) and 21 females (24.4%)] with an overall mortality of 33.7% (29 patients). The average age was 50.37 years and trauma was the commonest aetiology (34 patients, 66.7%). The average duration of symptoms prior to presentation was 10.56 days; the lower limb was most commonly involved (62 patients, 72.09%). Fifty nine patients had comorbidities (commonest being diabetes mellitus in 41). Age above 50 years, symptoms for more than 8.5 days, involved surface area more than 15.5%, of the total body surface, on-admission pulse rate more than 99 beats/minute, systolic blood pressure less than 103 mm Hg, Glasgow scale less than 12, need for inotropes, low hemoglobin, high leukocyte counts, uraemia, deranged coagulation, low serum albumin, and high levels of lactic acid were significant for mortality. On multivariate analysis, only age above 50 years, presence of acidosis and low serum albumin significantly affected survival. CONCLUSION: NSTI carry high mortality. The identification of potential risk factors associated with mortality might help in guiding and optimizing the management of patients who present with NSTI.

RESUMEN

AIMS: Diabetic foot ulcer is a dreaded complication of diabetes. Diabetic foot ulcer patients are often infected with multidrug resistant organism (MDRO) due to chronic course of the wound, inappropriate antibiotics treatment, frequent hospital admission, neuropathy, nephropathy, and peripheral vascular disease. MATERIALS AND METHODS: This prospective study was conducted in our 750 bedded hospital for a period of 6 months. The present study was undertaken to isolate various MDRO methicillin resistant Staphylococcus aureus; Gram-negative bacteria producing enzymes such as extended spectrum beta-lactamases (ESBL), Amp C, Carbapenamases; Pseudomonas and Acinetobacter species producing metallo-beta-lactamases (MBL). In addition we attempted to identify risk factors for association of diabetic foot ulcer and MDRO. RESULTS: A total of 149 bacterial isolates were identified. Of the total isolates 73.2% were Gram-negative and remaining 26.8% were Gram-positive bacteria. Among Enterobacteriaceae 59% were ESBL producers and 48% were Amp C producers. In addition, 41.5% of the isolates produced both ESBL and Amp C and 13.4% were carbapenem resistant Enterobacteriaceae. Among 20 Pseudomonas and Acinetobacter isolates, 5 were MBL producers (25%). Furthermore, in the study, 56% of patients with diabetic foot ulcer harbored MDRO. The risk of multidrug-resistant infection is significantly more in patients having diabetes duration >20 years and size of ulcer more than 4 cm2. CONCLUSION: The detection of MDRO in patients of diabetic foot ulcer changes the treatment strategies limits the antimicrobial options and causes higher complications among them.

RESUMEN

PURPOSE: The aim is to study the clinical profile and outcome of patients presenting with diabetic foot infections (DFI). METHODS: This was a prospective study recruiting patients >18 years of age, with DFI. All patients underwent a detailed history and clinical examination. Patients were classified as per the International Working Group on the Diabetic Foot -IDSA classification. The patients were followed up every month for 3 months. Clinical outcome was studied regarding the rate of amputations, readmissions, and mortality. RESULTS: There were 65 patients with a mean age of 58.49 ± 11.04 years with male predilection (83.08%). Mean duration of diabetes mellitus was 12.03 ± 6.96 years. Ulcer (92.31%) and discharge (72.31%) were the most common presenting complaints. Monomicrobial growth was present in 36 patients (55.38%). Majority of isolates were Gram-negative (71.43%). The most common isolates were Escherichia coli and Staphylococcus aureus (28.57% each). Mild, moderate, and severe DFI was present in 40%, 47.69%, and 12.31% of patients, respectively. Severe DFI was associated with poor ulcer healing (P = 0.02) and higher number of major amputations (P < 0.001). Minor amputations were most commonly associated with moderate and severe DFI. Severe DFI had the highest number of readmissions (P = 0.04). Patients undergoing minor amputations had a significant association with area of ulcer (P < 0.001). CONCLUSION: This study shows the predominance of monomicrobial growth and Gram-negative organisms in diabetic foot patients. With increase in the severity of DFI, there was increased rate of hospital readmissions, amputations (major and minor), and mortality. Dimensions of ulcer may have a bearing on rate of minor amputations.

RESUMEN

Mucormycosis is an emerging opportunistic fungal infection. Increasing immunocompromization, widespread use of antibacterial and antifungal agents (such as voriconazole prophylaxis), carcinomas, transplantation and lifestyle diseases such as diabetes are the main contributors to this situation. The predominant clinical manifestations of mucormycosis vary from host to host, with rhino-orbital-cerebral, pulmonary, cutaneous, and gastrointestinal infections being the most common. In India, the prevalence of mucormycosis is approximately 0.14 cases/1000 population, which is about 70 times the worldwide-estimated rate for mucormycosis. The present study was undertaken over a period of five years (January 2009-December 2014) to determine the prevalence of mucormycosis. The samples suspected of mucormycosis were examined by direct KOH wet mount and cultured on Sabouraud's dextrose agar without actidione and on blood agar as per standard mycological techniques. Histopathological correlation was done for most of the cases. Antifungal susceptibility testing was performed by the EUCAST reference method. We identified a total of 82 cases of mucormycosis out of a total of 6365 samples received for mycological culture and examination during the said time period. Out of these, 56 were male patients and 27 were females. Most common presentation was rhino-orbito-cerebral (37), followed by cutaneous (25), pulmonary (14), oral cavity involvement (4) and gastrointestinal (2). The most common risk factors were diabetes and intramuscular injections. The fungi isolated were Rhizopus arrhizus (17), Apophysomyces variabilis (12), R. microsporus (9), Lichtheimia ramosa (8), Saksenaea erythrospora (5), Syncephalastrum racemosus (4), R. homothallicus (2), Rhizomucor pusillus (1), Mucor irregularis (1) and A. elegans (1). The mainstay of the treatment was amphotericin B, along with extensive surgical debridement whenever feasible. Most of the patients (50) recovered, but 25 died. The rest of the patients left against medical advice. "Nip in the Bud" should be the mantra for clinicians/surgeons for a favorable prognosis. Early diagnosis, prompt institution of appropriate antifungal therapy, surgical debridement whenever necessary, knowledge of risk factors and their timely reversal is the key for management.

RESUMEN

Amebiasis is common in tropical and developing countries with variable symptoms. Ameboma of the colon occurs rarely due to the annular growth of granulation tissue and can present as mass lesion simulating colonic carcinoma in elderly individuals. Due to diagnostic dilemma or in case of complications, for example, acute intestinal obstruction, perforation, or bleeding per rectum, the patient requires urgent surgical exploration and final diagnosis is made on histopathological examination.

RESUMEN

BACKGROUND: Saksenaea erythrospora is an emerging and recently described pathogenic fungus mainly causing invasive cutaneous infections. Globally, very few human cases, caused by S. erythrospora, have been reported. In India, among the genus Saksenaea, S. vasiformis was the only reported pathogenic species, until recently when a case of fungal rhinosinusitis was reported to be caused by S. erythrospora. We observed five human cases of necrotizing skin and soft tissue infections caused by S. erythrospora following traumatic implantation over 1-year study period. METHODS: The study was conducted for a year observing the causative role of Saksenaea species in primary cutaneous necrotizing infections. The clinical entities were diagnosed by both microbiological and histopathological examination of the skin biopsies. The final identification of fungal strains was done by comparing internal transcribed spacer (ITS) and D1-D2 domains of the LSU (larger subunit) of the nuclear ribosomal RNA (rRNA) sequences with those of type strains of the different species of Saksenaea. RESULTS: Out of total 23 cases of necrotizing skin and soft tissue infections, 5 were caused by S. erythrospora. Intramuscular injection into the gluteal region was the predisposing factor in four patients, while upper limb involvement, following medicated adhesive tape application, was seen in one patient. All patients were treated with liposomal amphotericin B (LAMB) along with extensive debridement of necrotic tissues. Four patients responded well however one died. CONCLUSION: Saksenaea erythrospora is an emerging mucoralean fungus isolated in India among patients undergoing inadvertent I/M injections entailing necrotizing fasciitis at the local site.

RESUMEN

An ectopic breast, that is present at a distance from the embryonic milk line, is an uncommon condition in the normal population. We describe a case with the presence of a breast in the dorsal region occurring in a patient with meningomyelocele and split cord malformation type I. A dorsally situated breast in a case of split cord malformation has never been reported previously in the literature. This case report highlights that an ectopic breast could be a marker of occult spinal dysraphism. This lesion should be corrected only after appropriate radiological investigations ascertain the underlying pathology.

RESUMEN

Background: The mucoralean fungi are emerging causative agents of primary cutaneous infections presenting in the form of necrotizing fasciitis. Aims: The aim of this study was to investigate a series of suspected necrotizing fasciitis cases by Apophysomycesspecies over one-year period in a northern Indian hospital. Methods: The clinical details of those patients suspected to suffer from fungal necrotizing fasciitis were recorded. Skin biopsies from local wounds were microscopically examined and fungal culturing was carried out on standard media. The histopathology was evaluated using conventional methods and special stains.Apophysomyces isolates were identified by their morphology and by molecular sequencing of the internal transcribed spacer (ITS) region of the ribosomal genes. Antifungal susceptibility testing was carried out following EUCAST guidelines and treatment progress was monitored. Results: Seven patients were found to be suffering from necrotizing fasciitis caused by Apophysomyces spp. Six isolates were identified as Apophysomyces variabilis and one as Apophysomyces elegans. Five patients had previously received intramuscular injections in the affected area. Three patients recovered, two died and the other two left treatment against medical advice and are presumed to have died due to their terminal illnesses. Posaconazole and terbinafine were found to be the most active compounds against A. variabilis, while the isolate of A. elegans was resistant to all antifungals tested. Conclusions: Apophysomyces is confirmed as an aggressive fungus able to cause fatal infections. All clinicians, microbiologists and pathologists need to be aware of these emerging mycoses as well as of the risks involved in medical practices, which may provoke serious fungal infections such as those produced byApophysomyces (AU)


Antecedentes: Los hongos mucorales son agentes emergentes causantes de infecciones cutáneas primarias presentes en forma de fascitis necrotizante. Objetivos: La finalidad de este estudio fue la de investigar una serie de infecciones sugestivas de fascitis necrotizante causadas por alguna de las especies de Apophysomyces a lo largo de un año en un hospital del norte de la India. Métodos: Se obtuvieron los datos de todos los pacientes con sospecha de fascistis necrotizante. Las biopsias de piel de la zona afectada fueron cultivadas en medios de cultivos estándar y se evaluaron histopatológicamente mediante tinciones convencionales y específicas para hongos. Los aislamientos de Apophysomyces fueron identificados morfológicamente y mediante la secuenciación del espaciador intergénico ribosomal (ITS). La sensibilidad antifúngica se determinó mediante el método EUCAST y la evolución de los pacientes fue monitorizada. Resultados: Se encontraron siete pacientes con fascitis necrotizante causada por especies de Apophysomyces. Seis aislamientos fueron identificados como Apophysomyces variabilis y uno como Apophysomyces elegans. Cinco pacientes habían recibido previamente inyecciones intramusculares en el área afectada. Tres pacientes se recuperaron, dos fallecieron y de los dos restantes no se tiene seguimiento médico, aunque presumiblemente fallecieron debido a que padecían enfermedades terminales. El posaconazol y la terbinafina fueron los compuestos más activos frente a A. variabilis, mientras que el único aislamiento deA. elegans fue resistente a todos los antifúngicos ensayados. Conclusiones: Se confirma que Apophysomyces es un hongo agresivo capaz de causar infecciones con desenlace fatal. Clínicos, microbiólogos y patólogos deben ser conscientes de los riesgos de estas micosis emergentes y de que determinadas prácticas médicas puedan provocar infecciones fúngicas graves como las producidas por Apophysomyces (AU)
