RESUMO
BACKGROUND & OBJECTIVES: Mixed-phenotype acute leukaemia (MPAL) is a rare neoplasm with no definite treatment protocols and a distinctly poor outcome. Advancement in polychromatic flow cytometry has made its identification easier. This prospective study was designed to identify cases of MPAL and study their clinical presentation and haematological profile in a tertiary care hospital in north India. METHODS: Ethylenediaminetetraacetic acid (EDTA)-anticoagulated bone marrow aspirate samples of patients diagnosed as acute leukaemia (AL) on the basis of morphology were utilized for immunophenotyping. A comprehensive panel of fluorochrome-labelled monoclonal antibodies targeting myeloid, B-cell, T-cell and immaturity markers was utilized. The patients diagnosed to have MPAL, on the basis of the World Health Organization 2008 classification, were selected for further analyses. RESULTS: There were 15 (2.99%) patients with MPAL of the total 501 cases of AL. Seven were children, all males and mean age of 5.08±3.88 yr. Eight were adults, male:female=6:2 and mean age of 21.43±5.74 yr. Eight were diagnosed as B/myeloid and seven were T/myeloid. No association was observed between age and immunophenotype of MPAL. On morphology, 11 were diagnosed as AML and four as ALL, and no specific morphology of blasts was predictive of a MPAL. INTERPRETATION & CONCLUSIONS: MPAL appeared to be a rare neoplasm (2.99% of AL cases). A comprehensive primary panel of monoclonal antibodies should be used to identify this neoplasm known to have a poor outcome.

Our study compared the diagnostic accuracy of the 10% alcohol-formalin cell-block (CB) technique against traditional smears (CS) in serous effusions over 1 year. CB outperformed CS by detecting 7 missed cases and diagnosing 177 benign, 5 suspicious and 26 malignant cases compared to CS's 180 benign, 9 suspicious and 19 malignant cases. Using histopathology as a gold standard, CB showed a sensitivity of 96.4%, specificity of 98.3% and diagnostic accuracy of 98.1%, significantly higher than CS's 79.3% sensitivity, specificity of 97.7% and 95.2% accuracy. Using a 10% alcohol-formalin method, CB also excelled in cytomorphological characterization, especially in background elements, cellularity and cellular architecture. CB offered improved diagnostic accuracy and allowed extra sections for additional tests. In resource-constrained settings, combining CS and CB enhances cytological assessment.
RESUMO
Ectopic pregnancy (EP) constitutes 1%-2% of all pregnancies and is one of the leading causes of maternal morbidity and mortality. The most common site of ectopic pregnancy is the ampulla. Ectopic ovarian pregnancy (EOP) is one of the rare events, with an incidence of 0.5%-3% of all pregnancies. The incidence is higher in intrauterine device users or assisted reproductive techniques. The precise aetiology and pathogenesis of EOP remain elusive. Clinically, EOP mirrors the presentation of tubal pregnancy or a ruptured luteal cyst, often leading to life-threatening hypovolemic shock. Transvaginal sonography is the primary diagnostic tool. Still pinpointing the exact location early on poses challenges, and it's usually misinterpreted as a tubo-ovarian mass, hemorrhagic cyst, or luteal cyst. Furthermore, while a suboptimal rise in serum beta-human chorionic gonadotropin (ß-hCG) levels may indicate pregnancy, it doesn't definitively confirm EOP. Only histopathological examination offers a conclusive diagnosis. This paper discusses an EOP case in a young woman who experienced five months of amenorrhea and exhibited no traditional risk factors, underscoring the significant challenges inherent in preoperative diagnosis.
RESUMO
Xanthogranulomatous salpingo-oophoritis is an infrequent and challenging inflammatory condition of the female genital tract. It involves the destruction of the fallopian tube and ovarian tissue by infiltrating inflammatory cells comprising lipid-laden macrophages, lymphocytes, plasma cells, and multinucleated giant cells. While more commonly found in other organs like the gallbladder and kidney, its occurrence in the female genital tract is rare. We present a case of xanthogranulomatous salpingo-oophoritis in a 45-year-old woman, shedding light on its diagnostic and clinical complexities. Notably, this case features a rare histopathological finding of coexisting salpingitis isthmic nodosa (SIN) with xanthogranulomatous inflammation, adding to its uniqueness.
RESUMO
OBJECTIVES: To combat misinformation, engender trust and increase health literacy, we developed a culturally and linguistically appropriate virtual reality (VR) vaccination education platform using community-engaged approaches within a Somali refugee community. DESIGN: Community-based participatory research (CBPR) methods including focus group discussions, interviews, and surveys were conducted with Somali community members and expert advisors to design the educational content. Co-design approaches with community input were employed in a phased approach to develop the VR storyline. PARTICIPANTS: 60 adult Somali refugees and seven expert advisors who specialise in healthcare, autism research, technology development and community engagement. SETTING: Somali refugees participated at the offices of a community-based organisation, Somali Family Service, in San Diego, California and online. Expert advisors responded to surveys virtually. RESULTS: We find that a CBPR approach can be effectively used for the co-design of a VR educational programme. Additionally, cultural and linguistic sensitivities can be incorporated within a VR educational programme and are essential factors for effective community engagement. Finally, effective VR utilisation requires flexibility so that it can be used among community members with varying levels of health and technology literacy. CONCLUSION: We describe using community co-design to create a culturally and linguistically sensitive VR experience promoting vaccination within a refugee community. Our approach to VR development incorporated community members at each step of the process. Our methodology is potentially applicable to other populations where cultural sensitivities and language are common health education barriers.

Embryonal rhabdomyosarcoma (ERMS) of the larynx in adults is an extremely rare diagnosis with insidious onset and progression. Only six reports (including this one) have been documented in the literature. Clinical presentation is dependent on the site, size, subtype of ERMS and growth rate. Hoarseness is the usual first symptom, followed by stridor and dyspnoea, with dysphagia being late in onset. Accurate staging and risk stratification is necessary to avoid overtreating/undertreating patients and should be guided by local Head and Neck/Sarcoma Multidisciplinary Teams. Treatment has moved away from radical therapeutic regimens to less-invasive, organ-preserving therapies. Long-term follow-up is required due to the risk of late recurrence.

BACKGROUND: Aberrant phenotypes in acute leukemia have been reported with varying frequencies in independent studies and their association with prognostic factors is still a matter of debate. AIM: This study aims to identify the frequency of aberrant immunophenotypes in de novo acute myeloid leukemia (AML) and to evaluate their association with initial clinical and hematological features. MATERIALS AND METHODS: A total of 181 patients of de novo AML were included during the time (July 2010-June 2012). The immunophenotype of all cases of AML was studied by using flow cytometry. RESULTS: Aberrant lymphoid antigen expression was seen in 43.1% cases. Most frequent aberrant lymphoid antigen was CD7, seen in 26.5% cases. All French-American-British (FAB) subtypes except AML-M3 expressed aberrant lymphoid antigens. The expression was most common in AML-M4 in the current study. CD34 expression in AMLs was significantly associated with the expression of aberrant lymphoid antigens. Lymphoid antigen expression in adult AML was significantly associated with higher white blood cell (WBC) count (>50,000/mm3) and higher number of peripheral blasts (>70%). CONCLUSION: In summary, CD7 is the most common aberrant lymphoid antigen expressed in AML. FAB subtype AML-M3 is usually not associated with aberrant lymphoid antigen expression. AML cases with CD34 positivity are more likely to express aberrant lymphoid markers. The current study also supports that aberrant lymphoid antigen expression in adult AML is associated with adverse presenting hematological features (WBC count >50,000/mm3, peripheral blasts >70%). Pediatric Ly + AML cases are not associated with adverse presenting clinical and biological features.

Enterobius vermicularis is an intestinal nematode commonly affecting children worldwide. Its transmission is by feco-oral route. Meckel's diverticulitis due to E. vermicularis infestation is an extremely rare presentation. An 11-year-old boy presented with acute abdomen. During surgery inflamed Meckel's diverticulum (M.D) was seen. Histopathology examination of specimen revealed E. vermicularis. Till date, only one case of E. vermicularis infestation of M.D is reported around five decades ago. This histopathological confirmation is extremely important as the required treatment (Mebendazole) of the infected case along with household contacts can prevent the spread of infection and may avoid surgery in known contacts.
RESUMO
A case of visceral leishmaniasis (VL)-associated hemophagocytic lymphohistiocytosis (HLH) in an immunocompetent native from a nonendemic area was reported. The patient belonged to Ravi river valley area (altitude 996 meters above the mean sea level) of Chamba, Himachal Pradesh, India. VL and HLH were not a differential diagnosis. Identification of the Leishman-Donovan bodies and hemophagocytosis in bone marrow aspirate and biopsy provided the diagnosis. The patient recovered to the treatment with amphotericin B.
RESUMO
BACKGROUND: Identification of aberrant antigen expression is important in characterizing neoplastic population among non.neoplastic bone marrow counterparts and further in the detection of minimal residual disease. (MRD). Flow cytometry (FCM) is an important tool in identifying aberrant phenotypes. Incidence of aberrant phenotypes varies considerably in independent studies and its association with prognostic factors is still debatable. AIM: To identify the prevalence of aberrant phenotypes on immunophenotyping in a large series of de novo acute lymphoblastic leukemia (ALL) and to evaluate any association with initial clinical and hematological features. MATERIALS AND METHODS: In the current study, 303 patients of de novo ALL were included from the Department of Hematology, PGIMER, Chandigarh during the time period (July 2010 to June 2012). The immunophenotype of all cases of ALL was studied using FCM. RESULTS: Aberrant myeloid antigen expression was seen in 42.5% cases. Most frequent aberrant myeloid antigen was CD13 (32.2% cases), followed by CD33 (27.2% cases) and CD117 (18.5% cases). The expression of CD117 was relatively frequent in comparison to earlier reports which describe its rare expression. Adult T- ALL showed higher expression of CD33 and CD117 than pediatric T-ALL (P = 0.032 and 0.043, respectively). Myeloid antigen expression in ALL was associated with lower WBC count (P < 0.05) and lower number of peripheral blasts (P < 0.05). Expression of CD34 was higher in My + ALL group (P < 0.05) than My- ALL group. CONCLUSION: In summary, CD117 is a relatively frequently expressed myeloid marker contrary to earlier reports which describes its rare expression. Pediatric and adult ALL cases with low blast count and CD34 positivity are more likely to express aberrant myeloid markers. Current study also supports that myeloid antigen expression in both adult and pediatric ALL is not associated with adverse presenting clinical and biological features.

BACKGROUND: Uterine angioleiomyoma is a very rare gynecologic tumor; only a few such cases have been reported to date and we have found no such tumor reported in an adolescent girl. CASE: We report the case of a uterine angioleiomyoma in an adolescent girl. It presented as a huge abdomino-pelvic mass. The girl had severe menorrhagia and severe anemia. Intra-operatively no distinct planes were found between myoma and myometrium. Due to severe hemorrhage, she underwent sub-total abdominal hysterectomy. SUMMARY AND CONCLUSION: Uterine angioleiomyoma is an extremely rare tumor since only 16 such cases have been reported to date. Its appearance in an adolescent girl seems to be the first case of its kind. So it is being reported not only to familiarize the managing physicians with the possibility of such a tumor and its variable presentation, but also to highlight the need for inclusion of this tumor in WHO classification of tumors of the female genital tract.

OBJECTIVE: The aim of the study was to generate baseline data for indications of gynecological surgeries, and to assess route of surgery and histopathology correlation in women undergoing major gynecological surgery in a rural tertiary level teaching hospital in India. MATERIALS AND METHODS: Surgical indications, route of surgery and histopathology findings were reviewed and analyzed retrospectively, in 922 patients (≥35 years age) who underwent gynecological surgery at Dr. Rajendra Prasad Government Medical College, Kangra, Himachal Pradesh, India from January 1, 2011 to May 31, 2013. RESULTS: Of 922 surgeries, 65 had malignancy (7%). Pelvic organ prolapse (POP) (32.3%) and leiomyoma uterus (29%) were two most common benign indications for hysterectomy. Ovarian tumors were present in 13% (25% of these were malignant). Postmenopausal bleeding (PMB) was seen in 5.5% (55% of these were malignant). CONCLUSIONS: All except 10% surgeries were done in the absence of definite histopathology diagnosis that is dysfunctional uterine bleeding (n = 42 [45%]), chronic pelvic pain/severe dysmenorrhea (n = 34 [36%]) and recurrent PMB (n = 17 [19%]). Majority of surgeries had histopathological correlation except for six cases (0.6%) of malignancy, which were missed on initial work-up. Majority of the surgeries were done abdominally. In rural areas of developing countries poverty, lack of regular follow-up, resource constraints and lack of technical skills (with respect to laparoscopic/robotic surgeries) pose major challenge in providing quality health care.
RESUMO
BACKGROUND: Genital ulcers in adolescent girls present a complex diagnostic dilemma. Of all the causes of painful vulval ulcer in a virgin girl, tuberculosis is an extremely rare possibility with no case reported in literature. CASE: We are reporting a case of tubercular vulval ulcer in a sexually inactive pubertal girl. She had a close contact with active tuberculosis, positive tuberculin skin test, and chronic granulomatous inflammation on vulval biopsy. Therapeutic trial was offered and on follow up visit after 4 weeks, lesion had completely resolved. SUMMARY AND CONCLUSION: Unlike previous case reports that describe tubercular vulval ulcers in sexually active or post menopausal women our patient was sexually inactive. In endemic areas tuberculosis should be considered in differential diagnosis of vulval ulcers irrespective of sexual history of the patient.

INTRODUCTION: Osteoradionecrosis of the mandible and temporal bones has been extensively reported in literature, but cases of avascular necrosis of the cervical spine following radiotherapy to the larynx appear to be extremely rare. A review of the English language literature has shown only one other case where radiotherapy treatment of a laryngeal carcinoma has resulted in osteoradionecrosis of the cervical spine. CASE PRESENTATION: We present the case of a 65 year old male patient who suffered from osteoradionecrosis of the cervical spine 20 years after radiotherapy treatment for a T1aN0M0 laryngeal carcinoma resulting in quadriplegia. CONCLUSIONS: Radiotherapy carries a long-term risk of complications, including osteoradionecrosis which may present 20 years later with significant implications.
