Comparison of ultrasound and computed tomography in the diagnosis of malignant ovarian tumours at tertiary care center

Background: Accurate diagnosis of ovarian tumours is a diagnostic challenge. Multiple modes are used for the early detection of ovarian tumours. Early detection provides a survival advantage. Ultrasonography (USG), computed tomography (CT) and magnetic resonance imaging (MRI) are important imaging modalities in this regard. This study aims to compare the diagnostic accuracy of USG and CT imaging in the detection of malignant ovarian tumours.Materials: An observational cross-sectional study is conducted in the department of radiodiagnosis of Narayan medical college and hospital, Bihar over a period of 18 months from August 2021 to March 2024. Fifty-three patients with suspected ovarian malignancy who were not pregnant or had contraindications for administration of contrast media were included in the study. USG, CT and histopathology reports were compared for diagnostic accuracy with respect to different components.Results: Mean age of the patients was seen to be 49.6�.8 years. Abdominal pain was the most common presentation Majority of the patients had vascular lesions with a well-differentiated margin, heterogenous enhancement and septations. USG and CT agree almost perfectly in, identifying septations, calcification, and in differentiating margin of the tumours and very poorly for the identification of lymphadenopathy. CT had better sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) when compared to USG for diagnosis of ovarian malignanciesConclusions: CT has superior diagnostic accuracy compared to USG for diagnosis of ovarian tumours. However, USG provides similar diagnostic accuracy for identifying septations, calcification, and in differentiating margins of tumours.

A rare prostatic tumour masquerading clinically as benign prostatic hyperplasia

Prostatic tumours are usually benign. Malignant tumours are usually adenocarcinoma. Rare benign prostate tumours include inflammatory myofibroblastic tumours, which can be found in various body parts and are frequently identified in the lung or abdominal cavity of children and young adults. Inflammatory myofibroblastic tumours of the urinary tract present more often in kidneys. Prostatic inflammatory myofibroblastic tumours are sporadic and rare. Presenting 44 years old male with complaints of gross hematuria for 15 days with recurrent urine retention. Per rectal examination revealed, grade II prostate enlargement was firm in consistency. PSA was mildly raised (4.4 ng/ml). Ultrasound abdomen showed enlarged prostate (volume -40 cc) with irregular margins and heterogeneous echo texture showing increased flow on colour Doppler. Transrectal ultrasound (TRUS) showed a well-defined irregular heterogeneously echoic mass in the transitional zone, but TRUS biopsy showed no malignancy. After TURP, prostate chip examination showed inflammatory myofibroblastic pseudotumour of the prostate. Di?erentiation of inflammatory myofibroblastic prostate tumours from malignant tumours through imaging and laboratory tests is di?cult. A case of prostatic inflammatory myofibroblastic tumour observed after transurethral resection of the prostate to treat prostate hyperplasia in a 44-year-old man is presented in this report.

In the past two years, PD-1\PD-L1 and CTLA-4 inhibitors, especially Nivolumab, Pembrolizumab, Atezolizumab and Lpilimumab, have been used in non-small cell lung cancer, colon cancer. Promising results have been obtained in malignancies such as melanoma and urinary tract cancer. Traditional Chinese medicine has a long history in China. Modulating immune checkpoints has certain advantages in treating malignant tumors, and it has shown good efficacy in improving its adverse events. This article reviews the role of traditional Chinese medicine in regulating immune checkpoints and improving adverse reactions and its application prospects in immunomodulatory treatment.

Exploring the unusual: a testosterone-secreting ovarian tumor

ABSTRACT Ovarian steroid cell tumors are rare, representing less than 0.1% of all ovarian neoplasms. Among the myriad causes of hirsutism, ovarian tumors account for 1% of the reported cases. We present the case of a 49-year-old parous postmenopausal woman who sought medical attention for hirsutism for 2 years. This case illustrates the unusual and interesting connection between rare ovarian pathology and the clinical manifestation of hirsutism in a postmenopausal patient. Her ultrasonography and MRI showed a right adnexal mass of solid-cystic consistency with thin septations. Her laboratory workup revealed high levels of total testosterone of 256 ng/ml (8.4-48.1ng/ml) and free testosterone of 7.36 pg/ml (0.2-4.1 pg/ml), while DHEAS - 234 µg/dl (35.4-256 µg/dl) and CA125 - 15.8U/L (0.0-35 U/L) were in the normal range. She underwent exploratory laparotomy with a total abdominal hysterectomy and oophorectomy. Histopathological examination and immunohistochemistry conclusively established the presence of a steroid cell tumor, specifically classified as "Not Otherwise Specified"(NOS), in the right ovary.

A study on role of magnetic resonance imaging in the evaluation of intracranial neoplastic lesions

Background: Neoplastic central nervous system (CNS) lesions are a heterogeneous group of diseases with a variable outcome that reflects the precision of diagnosis and the delivery of optimal and specific treatment. CNS imaging has a pivotal role in directing management decisions. In the present study, cases of either clinically suspected intracranial neoplastic lesions or already diagnosed cases of neoplastic lesions were studied by cross sectional imaging of magnetic resonance imaging (MRI). Methods: In this prospective study, 30 cases of intracranial neoplastic lesions were studied by 1.5T Siemens Essenza MR scanner over a period of 6 months. Imaging findings were evaluated and tabulated. Results: Total 30 cases of in intracranial neoplastic lesions were studied aged between 12 to 87 years (17 men and 13 women). Most common presenting complaint was headache. Solitary lesions were present in 21 patients (70%) and multiple lesions in 9 patients (30%). 80% of the lesions were supratentorial, 13.3% were infratentorial and 6.6% were seen in both infra and supratentorial region. 76.6% were intra-axial and 23.3% were extra-axial. Metastasis were the most common neoplastic lesions; glial tumors are the second most common neoplastic lesions. Meningiomas were the most common benign tumors. Mass effect and perilesional edema were the most common associated findings. Conclusions: MRI is the first line of investigation for diagnosis and evaluation of intracranial neoplastic lesions with reasonable degree of diagnostic accuracy. Neuroimaging in combination with clinical findings can be helpful in early diagnosis and timed intervention.

It is also useful for exact categorization of cutaneous appendageal tumours.

A rare case report of Sertoli Leydig cell tumour of ovary

Sertoli-Leydig cell tumor (SLCTs) of the ovary, also known as androblastoma, is a rare neoplasm from the group of sex cord-stromal tumors of the ovary. They account for less than 0.5% of all ovarian tumors. They typically occur in young and reproductive women and the patients usually present with abdominal swelling or pain. A case of 35-year-old multiparous female presented with abdominal mass, ultrasonography revealed a large abdomino-pelvic complex solid cystic mass lesion arising from left ovary. She underwent staging laparotomy followed by total abdominal hysterectomy with left salpingo-ovariotomy and right salpingo-oopherectomy with partial omentectomy. Histopathological examination (HPE) revealed features suggestive of moderately differentiated SLCT of left ovary (with heterologous elements).

Approach to clinically significant vascular anomalies in children

Vascular anomalies consist of tumours or malformations made up of abnormal growth or collections of blood vessels that can result in functional or cosmetic problems. While many vascular anomalies are present at birth, some do not appear until later in life, making diagnosis more challenging. Although many vascular anomalies are benign, some are associated with serious complications and may involve multiple organ systems. This article highlights the important features of clinically significant vascular anomalies to help physicians promptly identify and refer these cases to a specialised multidisciplinary team for evaluation and management. The discussion includes the various presenting complaints of vascular anomalies in children, namely, rapidly growing birthmarks, painful lesions, seizures/neurological manifestations, bleeding diathesis, cardiac/airway abnormalities and part of an overgrowth syndrome.

Analgesic effect and safety of using an epidural analgesia pump versus an intravenous analgesia pump for uterine artery embolization in the treatment of uterine fibroids / 中国基层医药

Objective:To investigate the analgesic effect and safety of using an epidural analgesia pump versus an intravenous analgesia pump for uterine artery embolization in the treatment of uterine fibroids. Methods:Fifty patients with uterine fibroids undergoing uterine artery embolization admitted to The Second Affiliated Hospital and Yuying Children's Hospital of Wenzhou Medical University from January 2019 to December 2021 were included in this study. They were divided into an observation group and a control group ( n = 25/group). Patients in the observation group used an epidural analgesia pump for pain relief, while patients in the control group used an intravenous analgesia pump for pain relief. At 1, 6, 12, and 24 hours after surgery, pain severity was compared between the two groups using the Visual Analogue Scale. Comfort level was compared between the two groups using the Bruggemann Comfort scale. Before and after surgery, respiratory rate, heart rate, blood pressure, and adverse reactions were compared between the two groups. Results:At 1 hour after surgery, the Visual Analogue Scale score in the observation group was significantly lower than that in the control group [3.00 (2.00, 5.50) vs. 7.00 (6.00, 8.00), Z = -3.84, P < 0.05]. At 6, 12, and 24 hours after surgery, there was a significant difference in the Visual Analogue Scale score between the two groups (all P > 0.05). Within 24 hours after surgery, the use of opioid analgesics in the observation group was less than that in the control group [16.00% (4/25) vs. 88.00% (22/25), χ2 = 25.96, P < 0.001]. At 1 hour after surgery, the Bruggemann Comfort Scale score in the observation group was significantly higher than that in the control group [0.00 (0.00, 0.50) vs. 0.00 (0.00, 0.00), Z = 2.08, P < 0.05]. At 6, 12, and 24 hours after surgery, there was no significant difference in the Bruggemann Comfort Scale score between the two groups (all P > 0.05). After surgery, heart rate was significantly decreased in each group compared with before surgery (both P < 0.05). There were no significant differences in respiratory rate and mean arterial pressure between the two groups before and after surgery (both P > 0.05). There were no significant differences in the incidences of postoperative nausea, vomiting, and fever between the two groups (all P > 0.05). Conclusion:The epidural analgesia pump used for uterine artery embolization in the treatment of uterine fibroids has a better analgesic effect and provides more comfort and is safer than the intravenous analgesia pump. The former is worthy of clinical promotion.

Analysis on the implementation effect of single disease payment policy for day surgery based on difference-in-differences model / 中华医院管理杂志

Objective:To analyze the implementation effect of single disease payment policy for day surgery (hereinafter referred to as the policy), for references for the reform of medical insurance payment.Methods:By collecting the information of inpatients from 2017 to 2019 in a tertiary hospital, the research group took patients with colorectal benign tumor and nodular goitre as the policy implementation group and the control group respectively. 2017-2018 was the pre implementation stage of the policy, and 2019 was the post implementation stage of the policy. The difference-in-differences (DID) model was used to analyze the changes in indicators such as length of stay and hospitalization expenses after policy implementation, under whether the policy is implemented or not, as well as before or after policy implementation.Results:A total of 2 419 patients were included, including 927 patients with nodular goiter in the control group and 1 492 patients with colorectal benign tumors in the policy implementation group (688 patients before the policy implementation and 804 patients after the policy implementation). The results of DID showed that the hospital days for patients with colorectal benign tumor decreased by 56.53%, the hospitalization expenses decreased by 26.51%, the out-of-pocket expenses decreased by 26.66%, the treatment expenses increased by 11.96%, the drug expenses decreased by 50.29% and the consumables expenses decreased by 20.23% after the implementation of the policy.Conclusions:The implementation of the policy could reduce length of stay, hospitalization expenses and out-of-pocket expenses, optimize the structure of hospitalization expenses, improve the efficiency of hospital diagnosis and treatment, and help the hospital realize its transformation from a size expansion to a quality and benefit expansion.

Ependimoma de fosa posterior en una embarazada: diagnóstico diferencial de una hiperémesis. Reporte de caso / Posterior fossa ependymoma in a pregnant woman: differential diagnosis of hyperemesis. Case report

Resumen ANTECEDENTES: Los tumores intracraneales se diagnostican con una frecuencia muy baja durante el embarazo. Entre los síntomas iniciales destacan: cefalea, náuseas y vómitos frecuentes que, a su vez, son característicos del embarazo, de ahí la necesidad de establecer un diagnóstico diferencial correcto. CASO CLÍNICO: Paciente primigesta, de 25 años, 11+4 semanas de embarazo, con un cuadro de vómitos, cefalea, vértigo e inestabilidad, de inicio subagudo en los últimos dos meses. Antecedentes de interés: cefalea de características tensionales en comparación con migraña crónica no estudiada previamente. Durante la exploración se advirtió enlentecimiento en el lenguaje, nistagmo evocado por la mirada de manera bilateral y dolor periocular izquierdo, junto con vómitos incoercibles que no cedían, pese a la dieta absoluta y administración pautada de metoclopramida y pantoprazol. La resonancia magnética nuclear cerebral con contraste mostró una masa tumoral centrada en el cuarto ventrículo. Con base en lo anterior se procedió a la craniectomía suboccipital con exéresis subtotal del tumor y diagnóstico anatomopatológico de ependimoma de fosa posterior grupo A. Se propuso, y la paciente aceptó, la interrupción del embarazo con el propósito de completar el tratamiento coadyuvante con radioterapia. La intervención quirúrgica le dejó importantes secuelas neurológicas que ameritaron un proceso de rehabilitación. CONCLUSIONES: El momento del diagnóstico es decisivo para indicar el tratamiento de las tumoraciones intracraneales, sobre todo si son de naturaleza maligna, puesto que habrá que establecer un equilibrio entre la salud de la madre y la viabilidad de la gestación. En tanto se trata de pacientes con una afección compleja, su atención médica debe ser multidisciplinaria para disminuir los riesgos para la madre y el feto.

Abstract BACKGROUND: Intracranial tumours are diagnosed very rarely during pregnancy. The initial symptoms include headache, nausea and frequent vomiting, which are characteristic of pregnancy, so a correct differential diagnosis is necessary. CLINICAL CASE: Primigravida patient, 25 years old, 11+4 weeks pregnant, with a history of vomiting, headache, dizziness and instability of subacute onset in the last two months. History of interest: tension-type headache compared with chronic migraine, not previously studied. On examination, slowed speech, bilateral gaze-evoked nystagmus and left periocular pain were noted, together with incoercive vomiting that did not resolve despite a strict diet and prescribed metoclopramide and pantoprazole. A contrast-enhanced MRI of the brain showed a tumour mass centred in the fourth ventricle. Based on the above, a suboccipital craniectomy was performed with subtotal excision of the tumour and anatomopathological diagnosis of group A posterior fossa ependymoma. The interruption of pregnancy was proposed and accepted by the patient to complete the adjuvant treatment with radiotherapy. The surgical intervention left her with significant neurological sequelae that merited rehabilitation. CONCLUSIONS: The time of diagnosis is crucial in the management of intracranial tumours, especially if they are malignant, as a balance must be struck between the health of the mother and the viability of the pregnancy. As these are patients with a complex condition, their medical care must be multidisciplinary in order to reduce the risks to the mother and foetus.

The clinical and pre and postoperative profile suggested Summary and Conclusion: IDEM spinal cord tumours were common in 3rd decade, with male predominance. Commonest location was dorsal area with meningioma being the commonest histopathological finding.

Detection of Neuroendocrine Tumour of Sphenoid Sinus on the Gallium-68 DOTATATE PET/CT: A Rare Entity

@#Neuroendocrine tumours (NETs) are a category of neoplasm that is characterised by its phenotypic and heterogeneity. The occurrence of this type of neoplasm in the nasal cavity and paranasal sinuses is extremely rare accounting for only 0.2-0.8% of all cancers. NET tends to expresses somatostatin receptors (SSTR) and owning to this unique characteristic, molecular imaging has been able to detect these tumours using radiolabelled somatostatin analogue agent. Gallium-68 (Ga-68) DOTATATE PET/CT is an example of SSTR imaging and has been shown to be of importance in the assessment and staging of NET. We present a case of a rare sphenoid sinus NET in a 45-year-old gentleman whom initially presented with persistent left eye pain which led to visual loss. We described the utilization of Ga-68 DOTATATE PET/CT in the diagnosis and staging of this patient which in turn dictated treatment approach.

The effect of CAM comprehensive nursing interventions on the improvement of quality of life to patients with breast cancer and gynaecological tumours

Breastcancerin females, which is consideredthe most dreadfuldisease in India andthe worldas compared toother gynaecological cancers,demands extensive care and proper medicationin order to control itsprogressive growth. In addition to the conventional care ofthe patients, Complementary andAlternative Medicine(CAM)is administeredin a controlled way through proper guidance and counselling in orderto attainimprovedphysical andmental health forthe patients.Objective: The aim of the study wasto assess the effectiveness of CAMcomprehensive nursing interventionsand their benefit forpatients who havebreast cancer and gynaecological tumours.Methods: Statistical data was used to map the adult womendiagnosed with breast and gynaecological cancer and who were set to start new chemotherapy treatments. A total of 450 patients from different states of East India were enrolled in the studyover a period of four years. The patients wereselectedbased on their preference for undergoing CAM.The research was conducted usingacross-sectionalanonymous self-administered questionnaireto examine women's perspectivestowards the use of CAM and itseffect on their mental andphysical health.Results:42%of the women preferred theuseofCAM astheir alternative treatment. Breast cancer patients disclosed that 48.1% of them had used CAM and 39% of women with gynaecological cancersstated that they had usedCAM. The results further indicated a less frequent deteriorationin the health of CAM users(38.4%) thantonon-users(55%). In terms of those who utilizedvitamins and nutritional diets,60% of the participants reported using a proper diet, including antioxidants, minerals, vitamins and herbs etc. 37% opted for spiritual healing through yoga, 26% utilized energy healing, 42.4% utilized acupuncture,72% preferred massagesand 23% of patients utilized chiropractic methods.The use of CAM was foundmainlyin the patients with proper education and awareness and those with a family history of cancer who were not receiving the necessary care from their previous primary physician.Conclusion:CAM still requiresextensive research in terms of its applications in dealing with patients and in orderto successfully launch programmes aimed at promoting its useworldwide andto eradicate all the other false notions about it.[Ethiop. J. Health Dev. 2022; 36(2):000-000]Keywords: Breast Cancerand gynaecological tumours,Complementary And Alternative Medicine (CAM), Complementary Oncology,Quality Of Life, Nutritional Diet and Spiritual Healing, HRQL (Health-Related Quality Of Life).IntroductionCancer has been the primaryconcern in Indiafrom the onset,resulting in thousands of deaths due to the lack of adequatemedication and therapy.Breast cancer is considered to bea common invasive form of cancer which is responsible for the second highest mortality rate among the primaryfatal conditions of cancer-causing deaths in women. Under the National Cancer Registry Program,the breast, cervix, uteri,and oral cavity(7)are the most common cancer sitesin women. According to statistics, 50-60% of all cancers amongIndian women are commonly found inthe cervix uteri, breast, corpus uteri and ovaries,which are the main organs forcancer invasion. The percentage of women who experience these types of cancer is increases, with more women becoming susceptible to breast cancer, in women up to 3-8% suffer fromovarian cancer,0.5-4.8%have cancer of the corpus uteri, 1-3% have vulva and/or gestational trophoblastic tumours and a staggering75,000 or more women have breast cancer. With the advancements of the disease through time,research programs were also improved in order to enable the improvement of existing measures and/or the development of new measures aimed at combating the diseas and decreasing mortality rates. Apart from the conventional chemotherapy technique,various other programs have been introduced andencorporated into treatment regimes in order to improve the lives of those who are affected by cancer.Complementary andAlternative Medicine (CAM) emphasizesthe methods and practices that are therapeutic and which help diagnose or curethe disease,these methods are intended tocomplement the conventional methods and can be used in place of mainstream medicine. Women with breast cancer and other gynaecological tumoursare increasingly inclined towards the use of CAM. With the increasing number of cancer reports in Indiaand the world,and with the principal amount leading to mortality, women with proper education and awareness are inclined to choosealternative methods rather than the old conventional ones. The side-effects resulting from the chemotherapy are immense and toxic,which is one of the reasons women are inclined to choose.Various research projects and cumulative studies have been conducted in order to review and discoverthe

Histopathological pattern of Orbito-Ocular Lesions, a retrospective hospital-based study spanning 15 years

Background: Many previous studies on orbito-ocular lesions are skewed in favour of the neoplastic lesions in general and the malignant lesions in particular. This, therefore, creates a vacuum on the spectrum of these lesions, thus may result in problematic diagnostic bias by the ophthalmologist and pathologist. Objective: To give the spectrum and relative frequencies of orbito-ocular biopsies and by extension orbito-ocular lesions/diseases at the University of Benin Teaching Hospital (UBTH). Materials and Methods: A retrospective descriptive study of all cases of orbito-ocular biopsies with histopathologic diagnosis. Results: There were 236 orbito-ocular biopsies. The male to female ratio was slightly in favour of the females. Orbito-ocular biopsies had a wide age range that spanned from the 1st to 10th decade, mean age in the 3rd decade (20-29years) and a peak age in the 1st decade (0-9 years). The neoplastic lesions were the prevalent indication for orbito-ocular biopsies (63.72%) while the conjunctiva (58.10%) was the most common site for orbito-ocular biopsies. Conclusion: This study noted a wide array of orbito-ocular lesions for which biopsies were done for histopathological diagnosis. This we hope will in no small measure increase the diagnostic precision of the ophthalmologist and the pathologists in our own environment

Molecular genetic analysis of primary renal epithelial tumours with granular oncocytic cytoplasms / Análisis genético molecular de tumores epiteliales renales primarios con citoplasma oncocítico granular

SUMMARY: The group of primary renal tumours with granular-oncocytic cytoplasm is a very heterogeneous group, in its histological origin and biological behavior resulting in many diagnostic problems. In this study 57 renal epithelial tumours with granular oncocytic cells were analyzed using fluorescence in situ hybridisation (FISH), array comparative genomic hybridisation (aCGH) and polymerase chain reaction (PCR). The results of analysis in renal oncocytoma (RO) did not indicate the presence of the gene mutations or chromosomal abnormalities. Sporadic renal hybrid oncocytic/chromophobe tumours (HOCT) had multiple numerical aberrations of chromosomes 1, 2, 6, 9, 10, 13, 17, 20, 21 and 22. This type of tumour had no mutations in the VHL, c-kit, PDGFRA, and FLCN genes. Oncocytic papillary renal cell carcinoma (O-PRCC) had numerical abnormalities of chromosomes 7 and 17 and the loss of the Y chromosome. Cytogenetic analysis of 20 pigmented microcystic chromophobe renal cell carcinomas (PMChRCC) showed monosomy as the most frequent aberration in all analyzed chromosomes 1, 2, 5, 10, 13, 17 and 21. One case of chromophobe renal cell carcinoma (ChRCC) with hyaline globules had a mutation in the distal part of exon 3 of the VHL gene. Absence of genetic disorders in usual RO is common result, but we have established absence of genetic disorders even in rare variants. Variety of genetic alterations detected in sporadic renal HOCT proves it to be a separate entity, not a variant of ChRCC, while PMChRCC is an uncommon variant of ChRCC. O-PRCC is a subtype of papillary renal cell carcinoma.

RESUMEN: El grupo de tumores renales primarios con citoplasma granular-oncocítico es un grupo muy heterogéneo, en su origen histológico y comportamiento biológico, resultando en problemas de diagnóstico. En el estudio se analizaron 57 tumores epiteliales renales con citoplasma oncocítico granular mediante hibridación fluorescente in situ (FISH), hibridación genómica comparativa de matriz (aCGH) y reacción en cadena de la polimerasa (PCR). Los resultados del análisis en oncocitoma renal (RO) no indicaron la presencia de mutaciones genéticas ni anomalías cromosómicas. Los tumores oncocíticos / cromófobos híbridos renales esporádicos (HOCT) tenían múltiples aberraciones numéricas de los cromosomas 1, 2, 6, 9, 10, 13, 17, 20, 21 y 22. No se observaron mutaciones en este tipo de tumor en el VHL, c-kit, PDGFRA y genes FLCN. El carcinoma de células renales papilar oncocítico (O-PRCC) tenía anomalías numéricas de los cromosomas 7 y 17 y la pérdida del cromosoma Y. El análisis citogenético de 20 carcinomas de células renales cromófobos microquísticos pigmentados (PMChRCC) mostró que la monosomía era la aberración más frecuente en todos los cromosomas analizados 1, 2, 5, 10, 13, 17 y 21. Un caso de carcinoma de células renales cromófobo (CCRc) hialino tenía una mutación en la parte distal del exón 3 del gen VHL. La ausencia de trastornos genéticos en la OI habitual es un resultado común, pero hemos establecido la ausencia de trastornos genéticos incluso en variantes raras. Varias alteraciones genéticas detectadas en esporádica HOCT renal demuestran que es una entidad separada, no una variante de ChRCC, mientras que PMChRCC es una variante poco común de ChRCC. O-PRCC es un subtipo de carcinoma papilar de células renales.

Pediatric Adrenocortical Oncocytoma presenting as Cushing’s Syndrome and Peripheral Precocious Puberty:A case report and review of literature / Journal of the ASEAN Federation of Endocrine Societies

@#Oncocytic adrenocortical tumours (OATs) or oncocytomas are extremely rare and are usually benign and nonfunctional. We report the case of a 4-year-old male with a right-sided, functional oncocytic adrenocortical adenoma, who presented with precocious puberty and Cushing’s syndrome. After work-up, the patient underwent laparoscopic adrenalectomy. The excised adrenal mass weighed 21 g and measured 3.5 cm in maximum dimension. Histological examination demonstrated no features suggestive of aggressive biological behaviour. The patient had no features of recurrent or metastatic disease and had prepubertal testosterone levels with suppressed hypothalamic-pituitary-adrenal axis twelve months after the surgery. A discussion of this case and a review of the literature on functional OATs in the pediatric population are presented.

Enzyme-Linked Immunosorbent Assay Detection For Malignancy Using Anti-P53 Antibodies

@#Tumour protein 53 (p53) plays an important role in the instruction of the cell cycle. In a variety of transformed cell lines, tumour protein is expressed in high amounts, and it is believed to contribute to transformation and malignancy. This research aimed to detect the anti-p53 antibodies in sera of patients with various malignant tumours and to evaluate the sensitivity and specificity of an enzyme-linked immunosorbent assay (ELISA). A case-control study was conducted on samples from 49 patients with various types of malignant tumours at Sultanah Bahiyah Hospital, Alor Setar, Kedah, Malaysia, and 32 healthy control cases with non‐malignant disease collected from Universiti Sains Malaysia clinic, Penang, Malaysia. The antibodies against p53 protein in the serum samples were analysed using the commercial ELISA kit, Calbiochem® p53- ELISAPLUS. The results showed that the rate of anti-p53 antibodies in patients with various malignant tumours was 13 out of 49 (26.5 %), compared with only 2 out of 32 (6.25%) in healthy controls (p < 0.001). The sensitivity of this kit reached 28.6% and the specificity was 93.8%. In conclusion, these results suggest that the anti-p53 antibodies can be detected in different sera of malignant tumour patients and the ELISA kit is highly specific; nevertheless, its discrimination power is not perfect because of its low sensitivity to determine the anti-p53 antibodies.

Management of Recurrence of Ameloblastoma and Odontogenic Keratocyst: A Cross-Sectional Study / Manejo de la recurrencia del ameloblastoma y keratoquiste odontogénico: Estudio de corte transversal

Abstract Objectives: Odontogenic keratocyst (OKC) and ameloblastoma are slowly growing and locally invasive tumors with high recurrence rate. The aim of this study was to investigate the clinicopathologic features of recurrent ameloblastoma and OKC cases, and evaluate outcomes of our treatments in terms of recurrence. Material and Methods: A total of 23 patients with confirmed recurrent ameloblastoma or OKC and treated in our clinic within eleven years period were reviewed retrospectively. Results: Eleven recurrent OKC cases and twelve recurrent ameloblastoma cases were included. Most recurrences occurred within five years after the initial treatment (69.6%). Enucleation had the highest recurrence rate among the first treatments (18/23). All recurrences were located in the mandible, with one exception (22/23). All recurrent OKCs were multilocular. Different histopathologic subtypes of ameloblastoma were seen in our study, follicular ameloblastoma was the most common (8/12). The mean diameter of the lesions was 4.3 cm (ranging from 2 cm to 7 cm). Statically significant relation was found between location and diameter of lesion and year of recurrence onset (p=0.004; p=0.026). We performed radical treatments in these cases (ten patients underwent marginal resections, and thirteen patients underwent segmental resection), and no recurrence was observed during the follow-up period. Conclusion: Previous inadequate surgical procedures were the most important cause of recurrence. Marginal or segmental resection with safety margins is the best method to treat recurrences of OKC or ameloblastoma cases.

Resumen Objetivo: Los keratoquistes odontogénicos (KQO) y ameloblastomas son tumores invasivos de lento crecimiento local con una alta tasa de recurrencia. El propósito de este estudio fue investigar las características clínico patológicas de los casos de ameloblastoma y KQO recurrentes y evaluar los resultados de tratamientos en término de recurrencia. Materiales y Métodos: Un total de 23 pacientes con casos confirmados de ameloblastomas o KQO recurrentes tratados en nuestra clínica en un período de once años fueron incluidos. Resultados: Once casos de KQO recurrentes y doce ameloblastomas recurrentes fueron incluidos. La mayoría de las recurrencias ocurrieron en los primeros 5 años posteriores al tratamiento inicial (69.6%). La enucleación mostró la tasa de recurrencia más alta entre los tratamientos iniciales (18/23). Todas las recurrencias se presentaron en la mandíbula excepto por un caso (22/23). Todos los KQO fueron multiloculares. Distintos subtipos histológicos del ameloblastoma fueron detectados en el estudio y el ameloblastoma folicular fue el más común (8/12). El diámetro promedio de las lesiones fue de 4.3cm en un rango de 2cm a 7cm. Una relación estadísticamente significativa se encontró entre la ubicación y el diámetro de la lesión y el tiempo de aparición de la recurrencia (p=0.004; p=0.026). Se realizaron tratamientos radicales en los siguientes casos, diez pacientes tuvieron resecciones marginales y trece pacientes resección segmental; no se observaron recurrencias en el período de seguimiento. Conclusión: Procedimientos previos inadecuados fueron la causa más relevante de recurrencia. Resección marginal o segmental con márgenes de seguridad son el mejor método para tratar casos de ameloblastoma y KQO recurrentes.
