Pre-peritoneal Fat as a Guide to Extended View Total Extraperitoneal (eTEP) Repair for Inguinal Hernia.

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.

Phaeohyphomycosis: A study from tertiary health care center in North India.

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.

Initial retrocolic endoscopic tunnel approach: A promising technique for radical right hemicolectomy.

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.

Apophysomyces variabilis, an emerging and worrisome cause of primary cutaneous necrotizing infections in India.

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.

Isolation and morphology of circulating tumor cells by cell block technique in breast cancer.

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.

Evaluation of DNA ploidy and S-phase fraction in fine needle aspirates from breast carcinoma.

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.

Binding Pancreaticojejunostomy: Is It Safe?

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.

Evaluation of various risk factors associated with multidrug-resistant organisms isolated from diabetic foot ulcer patients.

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.

Mucormycosis: Battle with the Deadly Enemy over a Five-Year Period in India.

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.

Dorsal ectopic breast in a case of spinal dysraphism: A rare entity.

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.

Primary germ cell tumor of the mediastinum - presenting as a huge mass.

Germ cell tumors compromise 15-20% of all anterior mediastinal masses; 50-60% of these are benign mediastinal teratoma. There may be mature, immature, and rarely with malignant component within the tumor mass. There are more chances of malignancy with immature type. We are reporting a case in 20-year young male diagnosed as giant benign cystic teratoma which was adherent to superior vena cava. The patient underwent surgical excision. In follow up of 2 years, the patient is not having any complaints.

Primary tuberculosis of the breast presented as multiple discharge sinuses.

Breast tuberculosis is a rare form of tuberculosis (TB). It is mainly classified as primary and secondary forms. Primary form is rare. We are reporting a case of primary TB breast with history of breast lump and multiple sinuses. TB was diagnosed on FNAC. Patient was put on anti-tubercular drugs.

Complete bronchial transaction due to severe blunt trauma and chest; treatment and outcomes : A distinct entity.

An 18-year-young male patient came to the emergency department with history of severe blunt trauma. He was having respiratory distress and diagnosed as bronchial injury on the right side. A chest tube was put immediately and there was continuous air leak in the form of air bubbles in the intercostal chest tube bag with each inspiratory effort. Chest injury can be a life-threatening condition, if not managed timely and properly. Bronchoscopy showed injury over the right main bronchus. The features of this uncommon entity are discussed, with special emphasis on early diagnosis and surgical management.

An unusual case of chest wall desmoid tumor.

Desmoid tumor of the chest wall are uncommon fibromatous tumors characterized by their local invasion and frequent recurrences. Extra-abdominal sites are mainly the shoulder girdle, the pelvic girdle and distal ends of the lower limbs. The chest wall represents 8-10% of cases and the tumor is exceptionally intrathoracic. We present here a rare case of a large desmoid tumor of left antero-lateral chest wall. In the presented case, wide excision of the tumor and chest wall reconstruction was done. There was no recurrence in 3 years of follow up.

Intraoperative evaluation of sentinel lymph nodes in breast carcinoma by imprint cytology, frozen section and rapid immunohistochemistry.

Sentinel lymph nodes (SLN) isolated in 40 patients of breast carcinoma (stage T(1)/T(2)) were evaluated intraoperatively by imprint cytology and frozen section. Rapid immunohistochemistry (IHC) was done in cases where both imprint smears and frozen sections were negative for any metastatic tumor deposits. The results of these different techniques were compared with postoperative paraffin sections taken as "Gold Standard." Nottingham modification of Bloom Richardson scoring system was used for grading the tumors. Further, the correlation of the SLN status with tumor size, grade, and lymphovascular invasion was studied. The sensitivity, specificity, and overall accuracy of imprint cytology were 91.7, 100, and 95% respectively, and those of the frozen section were 95.8, 100, and 97.5% respectively. Examination of multiple serial sections improved the sensitivity and overall accuracy of frozen section. Results of intraoperative rapid IHC were equivalent to final paraffin sections. Histological grade and lymphovascular invasion were in direct correlation with SLN metastasis (P < 0.05). The risk of lymphovascular invasion increased from 22.2% in grade I tumors to 85.7% in grade III tumors. SLN biopsy is a reliable method to evaluate the status of the axillary lymph nodes. Imprint cytology can be used reliably where the facility of frozen section is not available.
