RESUMEN
OBJECTIVE: To evaluate the role of contrast-enhanced ultrasound (CEUS) in the differential diagnosis of solid pancreatic head lesions (SPHL). METHODS: This prospective study comprised consecutive patients with SPHL who underwent CEUS evaluation of the pancreas. Findings recorded at CEUS were enhancement patterns (degree, completeness, centripetal enhancement, and percentage enhancement) and presence of central vessels. In addition, time to peak (TTP) and washout time (WT) were recorded. The final diagnosis was based on histopathology or cytology. Multivariate analysis was performed to identify parameters that were significantly associated with pancreatic ductal adenocarcinoma (PDAC). RESULTS: Ninety-eight patients (median age 53.8 years, 59 males) were evaluated. The final diagnosis was PDAC (n = 64, 65.3%), inflammatory mass (n = 16, 16.3%), neuroendocrine tumor (NET, n = 14, 14.3%), and other tumors (n = 4, 4.1%). Hypoenhancement, incomplete enhancement, and centripetal enhancement were significantly more common in PDAC than non-PDAC lesions (p = 0.001, p = 0.031, and p = 0.002, respectively). Central vessels were present in a significantly greater number of non-PDAC lesions (p = 0.0001). Hypoenhancement with < 30% enhancement at CEUS had sensitivity and specificity of 80.6% and 67.7%, respectively, for PDAC. There was no significant difference in the TTP and WT between PDAC and non - PDAC lesions. However, the WT was significantly shorter in PDAC compared to NET (p = 0.011). In multivariate analysis, lack of central vessels was significantly associated with a PDAC diagnosis. CONCLUSION: CEUS is a useful tool for the evaluation of SPHL. CEUS can be incorporated into the diagnostic algorithm to differentiate PDAC from non-PDAC lesions. KEY POINTS: ⢠Hypoenhancement and incomplete enhancement at CEUS were significantly more common in PDAC than in non-PDAC. ⢠Central vessels at CEUS were significantly associated with PDAC. ⢠There was no difference in TTP and WT between PDAC and non-PDAC lesions.

BACKGROUND: Pulmonary mucormycosis has been associated with high mortality (reported up to 100%) in renal transplant recipients. METHODS: This was a retrospective analysis of renal transplant patients with pulmonary mucormycosis between April 2014 and March 2020, who underwent surgical resection of the affected lung along with liposomal amphotericin therapy. Patients with lower respiratory illness features underwent chest X-ray, high-resolution computed tomography of the chest, and those with suspicious findings underwent analysis of bronchioloalveolar fluid and transbronchial lung biopsy. Patients with histological or microbiological evidence of mucormycosis were started on liposomal Amphotericin B. Tacrolimus and mycophenolate mofetil were stopped at the time of diagnosis. RESULT: Ten patients underwent combined management, while five patients were managed medically. At last follow up, seven out of ten patients (70%) who underwent combined management and two of the five patients (40%) who were managed medically, had a mean survival of 28.86 months (sd = 15.71, median = 25) and 14.17 months (sd = 12.21, median = 18), respectively, post-diagnosis of pulmonary mucormycosis. CONCLUSION: Surgical resection combined with antifungals in the perioperative period and decreased immunosuppression may improve the outcomes in renal transplant patients with pulmonary mucormycosis.

OBJECTIVE: Comparison of virtual CT enteroscopy (VCTE) using carbon dioxide with small-bowel enteroclysis (SBE) and capsule endoscopy (CE) in small-bowel tuberculosis (SBTB). METHODS: This prospective study comprised consecutive patients suspected to have SBTB. VCTE and SBE were performed on the same day and evaluated by independent radiologists. CE was performed within 2 weeks. VCTE was performed following insufflation of carbon dioxide via catheters in the jejunum and anorectum. A contrast-enhanced CT was followed by a delayed non-contrast CT. Image processing was done using virtual colonoscopy software. Findings on VCTE, SBE, and CE were compared. The final diagnosis of SBTB was based on either histopathological or cytological findings, response to antitubercular treatment, or a combination of these. RESULTS: Of the 55 patients in whom VCTE was performed, complete data was available in 52 patients. A final diagnosis of SBTB was established in 37 patients. All patients had VCTE and SBE. CE was performed in 34 patients. Adequate luminal distension was achieved in all patients with SBE and 35 patients with VCTE. SBE showed more strictures in jejunum (10.8%) and ileum (75.7%) compared with VCTE (jejunum, 8.1%, and ileum, 64.9%) and CE (jejunum, 5.9%, and ileum, 61.8%). However, difference was not statistically significant. VCTE revealed a greater length of strictures in both the jejunum and ileum compared with SBE and CE. CONCLUSION: VCTE allows adequate evaluation of the bowel in most patients with SBTB. It allows detection of greater length of abnormality in jejunum and ileum compared with SBE and CE. KEY POINTS: ⢠The use of VCTE using CO2 bowel insufflation in patients with SBTB should be considered. ⢠VCTE allows detection of a greater length of abnormality in the jejunum and ileum.

Germinomas are highly immunogenic tumors eliciting a strong peri-tumoral immune response that can spillover into the surrounding healthy tissues. This phenomenon can also occur in intracranial germinomas, manifesting as secondary hypophysitis. Herein, we report a case of 12-year-old-girl presenting with polyuria and polydispsia. She had central diabetes insipidus (CDI) and panhypopituitarism. Imaging revealed a sellar-suprasellar mass with infundibular stalk thickening. Transphenoidal biopsy revealed epithelioid granulomas with immunostaining negative for germinomatous cells. Other causes of hypophysitis were ruled out. Accordingly, she was diagnosed as primary granulomatous hypophysitis and treated with high-dose corticosteroids. Three years later she again presented with headache, vomiting and diminution of vision. Imaging showed a heterogeneous, solid-cystic peripheral rim-enhancing lesion at the same location with involvement of hypothalamus, ependyma and pineal gland. Cerebrospinal fluid beta-human chorionic gonadotropin was markedly elevated, confirming the diagnosis of an intracranial germ cell tumor. She was started on chemotherapy; however, she succumbed to febrile neutropenia. We performed a literature search and found 18 anecdotal cases of secondary hypophysitis associated with intracranial germinomas. There was a slight male preponderance (male:female 5:4). Two-thirds of the cases were below 18 years of age. Polyuria was the most common presenting manifestation (83%). CDI and panhypopituitarism were seen in 89 and 78% cases, respectively. Imaging evidence of pituitary stalk thickening was seen in 12 cases (67%), while pituitary enlargement and/or sellar mass were reported in 11 cases (61%). Pineal involvement was extremely rare, being reported in only 1 case, implying the predilection of suprasellar (rather than pineal) germinomas in causing secondary hypophysitis. Histologically, 82% had lymphocytic hypophysitis, while 18% had granulomatous hypophysitis. Initially, the diagnosis of germinoma was missed in 60% of the cases who were wrongly treated with corticosteroids. To conclude, physicians should make it a dictum that all children and adolescents presenting with CDI and pituitary stalk thickening should be rigorously screened for an underlying intracranial germinoma before labeling them as primary hypophysitis.

Breast masses are uncommon in children and adolescents. Ectopic breast tissue is further uncommon and may be present in locations such as the face, back, and thigh. A 12-year-old female child presented with a hard, nonmobile lump in the right breast. On exploration by submammary incision, the lump was found to be below the pectoralis major muscle and had no communication with the overlying orthotopic breast tissue. Histopathological examination revealed a well-encapsulated biphasic lesion, with features characteristic of a phyllodes tumor. We report a hitherto unreported case of aberrant breast tissue lying under the pectoralis muscle and containing phyllodes tumor.
RESUMEN
BACKGROUND & OBJECTIVES: : Celiac disease (CD) can exist in various forms in type 1 diabetes (T1D) patients and can remain undetected, leading to severe complications. This study was aimed to evaluate five commercially available anti-tissue transglutaminase (tTG) ELISA kits with distinct formats for the detection of CD and potential CD in T1D patients. Clinical and demographic profiles of the patients with different disease subsets were also studied. METHODS: : Fifty T1D patients with classical and non-classical symptoms of CD and 100 T1D patients without any symptoms of CD were included in this study. Anti-tTG autoantibody levels were estimated by five ELISA kits followed by histological examination of duodenal biopsy. HLA DQ2-DQ8 and DRB1-DQB1 typing was done, and serum levels for transforming growth factor (TGF)-ß1 were also estimated. RESULTS: : Assay format detecting anti-tTG IgA antibodies against recombinant antigens along with neopeptides of gliadin was most efficient in the detection of CD in symptomatic patients, and assay format detecting IgA+IgG helped in the detection of potential CD in asymptomatic T1D patients. These findings were supported by histological examination and human leucocyte antigen analysis. Patients with potential CD were found to have markedly deranged glycaemic control parameters and also had significantly raised serum levels of TGF-ß1, (P <0.05) compared to T1D patients. INTERPRETATION & CONCLUSIONS: : Potential CD can be frequently seen in T1D patients. This can be attributed to the dietary patterns prevalent in the subcontinent and the genetic basis of the disease. Anti-tTG IgA+IgG antibodies can be useful in the detection of these potential CD cases in T1D patients. Early intervention with gluten-free diet can be considered in these patients for better disease management.

The rising incidence of mangled extremity seen in modern trauma has lead to significant patient mortality. A lot of research is going on at microcellular level for a better understanding of tissue injury, repair and regeneration. PAX-7 is one such transcription factor, a marker of satellite stem cells in skeletal muscle. Though few studies have shown concrete evidence of increased expression of PAX-7 in the nearby injured zone in skeletal muscle post-injury, none has studied its expression in an event of mangled injury of limb in humans. We, hereby, attempted to identify whether PAX-7 expression of tissue near the zone of injury, after grievous trauma like mangled injury of extremities, actually increases, decreases or remains unaffected. A pilot study was conducted on 30 cases at a level 3 trauma centre; patients were segregated into two groups-group I with MESS score ≥ 7 and group II with score < 7. For group I patients, amputation was planned, and for group II, limb salvage surgery was planned. Skeletal muscle samples from three different zones (A, B and C) in group I, while pre- and post-debridement skeletal muscle samples in group II were sent for microscopic examination and IHC staining with PAX-7 antibody. A definite increase in PAX-7 expression, post-trauma near the zone of injury (Zone B and C in group I and post-debridement in group II), was noted. Increased expression of PAX-7 signifies increased recruitment of satellite stem cells near the injury zone, thereby reflecting the activation of skeletal muscle regeneration cascade. Hence, increased staining of PAX-7 in tissues could be a viable marker for identifying potential regeneration of skeletal muscle post-injury.

Mangled extremities were classically managed by amputation. But over the past few decades, with the advancement in surgical techniques, an increased number of limb salvages have been possible. As muscles usually get damaged in such grievous injuries, a thorough understanding of muscle regeneration may give a better insight into muscle healing in these injuries. Muscles are composed of slow and fast fibers which can be represented by slow and fast myosin, respectively. There are some animal studies which reported differential regeneration of slow and fast muscle fibers during muscle healing. We conducted this pilot study to find out whether the same holds true for muscle healing in mangled extremities also. This pilot study is designed in 15 patients with lower limb mangled extremities presenting to trauma center of PGIMER, Chandigarh, who were operated within 24 h of injury to see whether muscle healing in mangled extremities follows the same pattern. Biopsies were taken during initial surgery conducted within 24 h of injury and on the 7th day of injury when patient was posted again for secondary wound closure procedure or revision amputation. The biopsy samples were subjected to histopathological and immunohistochemistry examination using antibodies against fast and slow myosin. We found that the regenerating muscle fibers in the biopsy sample taken on the 7th day of injury showed only slow muscle fibers with the absence of fast muscle fibers when compared with the initial biopsy results showing differential regeneration of slow muscle fibers.

BACKGROUND: Disease activity in ulcerative colitis (UC) is best assessed clinically by Mayo score. 18-Fluorodeoxyglucose positron emission tomography-computerized tomography (FDG PET-CT) is a noninvasive imaging technique to assess extent, disease activity and response to treatment of UC, especially in high risk population or patients unwilling for endoscopy. AIMS: We conducted a prospective observational study with the aim of assessing and correlating UC disease activity by clinical criteria, endoscopy, histology, serum and fecal biomarkers, and FDG PET-CT. METHODS: Sixty eligible patients of UC were enrolled into three groups (26 remission, 24 moderate and 10 severe activity) as per Mayo score and FDG PET-CT was performed within 72 h of colonoscopy. ESR, CRP, and fecal calprotectin (FC) levels were determined for all patients. RESULTS: Of 60 enrolled patients, 10% patients had proctitis, 43.3% left-sided colitis, and 46.7% extensive colitis. ESR, CRP, FC levels, and rectal PET activity were significantly higher in groups with moderate and severe disease activity. Rectal PET activity showed a significant correlation with the Mayo score (k = 0.465, p < 0.001), endoscopic subscore (k = 0.526, p < 0.001), histological score (k = 0.496, p < 0.001), and FC (k = 0.279, p = 0.031). Extent evaluation by FDG PET-CT and colonoscopy showed a significant correlation (k = 0.582, p < 0.001). Besides, FDG PET-CT identified sacroiliitis in one patient and adenocarcinoma in one patient. CONCLUSION: FDG PET-CT is a reliable noninvasive tool for detection of disease activity, extent in UC with good correlation with Mayo score, histology and fecal biomarkers and accurate predictor of disease remission.

Microinvasive squamous cell carcinoma (SCC) is a known premalignant lesion of carcinoma cervix. It is also reported from other sites such as the oral cavity, larynx, and vulva. Microinvasive SCC is very rarely reported from the penis. We report the occurrence of microinvasive SCC in a long-standing erythematous lesion of glans penis in a patient, with extensive metastasis. We emphasize the need for awareness among patients and urologists about the premalignant lesions of penis and prompt treatment of such lesions to prevent possible spread of the disease.

We report a renal allograft transplant recipient with esophageal tuberculosis (TB) coinfected with herpes simplex virus (HSV) and Candida. The patient presented with oropharyngeal candidiasis and was started on fluconazole. Upper gastrointestinal endoscopy showed whitish patches with mucosal ulcers in the esophagus. Histopathological examination confirmed TB and HSV infection. The patient recovered after antiviral, antifungal, and anti-tubercular therapy with reduction in immunosuppression. In a TB-endemic zone, TB can coexist with opportunistic infections in an immunocompromised host.

Kawasaki disease (KD) is an acute febrile illness of childhood associated with vasculitis of medium-sized arteries especially the coronary arteries. Typical clinical features involving the skin, mucous surfaces, etc., occur sequentially over a few days. We report a rare presentation of KD as a surgical abdomen in a 2-year-old boy. Awareness of this presentation is important as it can otherwise lead to a delay in starting potentially life-saving intervention like intravenous immunoglobulins for cardiac complications kept cryptic by the manifest acute abdomen.
RESUMEN
Penile gangrene is very rare sequel of ischemic priapism. Previous published reports have shown its occurrence in patients with sickle cell disease, urethral carcinoma, bladder carcinoma, thrombotic thrombocytopenic purpura, idiopathic, traumatic, etc. Ischemic priapism with penile gangrene as an initial presentation of multiple myeloma has not been reported. We present a 44-year-old patient of multiple myeloma presenting with ischemic priapism and penile gangrene requiring partial penectomy.

ß-catenin (CTNNB1), an oncogene/onco-protein and an adhesion molecule is a key effector in colorectal cancer (CRC). Its activation, and subsequent up-regulation of Wnt-signaling, is an important event in the development of certain human cancers including CRC. Mutations in the ß-catenin gene in the region of serine-threonine glycogen kinase (GSK)-3ß phosphorylation target sites have been identified in colorectal cancer in humans. In the current study, we investigated 60 sporadic colorectal adenocarcinomas along with adjoining and normal mucosa cases in humans for ß-catenin mutations. Thirteen of sixty colorectal tumors from humans had point mutations with a frequency of 21.66% at codons 24, 26, 27, 32, 34, 35, 41, 42,43, 46, 49, 54, 55, or 67 sites which are mutated in colorectal cancer and some of these sites in other cancers. Thus, there appears to be a key involvement of ß-catenin activation in human colorectal carcinogenesis. mRNA expression analysis using q-Real Time PCR showed 21.5-fold up-regulation of ß-catenin mRNA in tumor tissue compared to normal and adjoining mucosa. Protein expression analysis using immunohistochemistry, confocal microscopy, and Western blot confirmed aberrant accumulation of ß-catenin protein along the nucleus and cytoplasm following mutation. The observed mutations and up-regulation of mRNA in tumors, and the increased expression of ß-catenin protein in CRC suggest that these alterations are early and prognostic events in sporadic colorectal carcinogenesis in humans. © 2015 Wiley Periodicals, Inc.

The purpose of this article was to draw attention to a periimplantitis-like clinical presentation of oral malignancy around dental implants, a phenomenon that may develop without any associated risk factors for oral cancer. Such a benign appearance of oral malignancy may lead to delay in the diagnosis and initiation of ensuing treatment. Therefore, chronic nonhealing inflammatory lesions around dental implants should be considered as highly suspicious.

Isolated ileal heterotopic pancreatic tissue as a lead point of intussusception in children is extremely rare. We report a 6-month-old female with ileoileal intussusception and a 4-year-old female with ileocolic intussusception both associated with gangrene. A review of literature suggests a higher prevalence of gangrene probably secondary to the pancreatic exocrine tissue.
