Cytological evaluation of p16Ink4a in precancerous lesions of the cervix: Conventional papanicolaou smears
Seema Singhal, Vinod Kumar Arora

Apollo Medicine 2020 17(4):240-245

Background: Cancer of the uterine cervix is the second most common cancer among women worldwide. More than three fourths of these patients are diagnosed at advanced stages, leading to poor prospects of long term survival and cure. Introduction of Papanicolaou (Pap test) cytological screening for cervical precancerous lesions has significantly reduced the incidence and mortality of cervical cancer. Human papillomavirus (HPV) DNA testing has been recently demonstrated to be efficient to be integrated into screening programs, so it can be used to triage women with equivocal cytological abnormalities and also identifies women at risk of residual or recurrent disease after treatment of cervical intraepithelial neoplasia. However, it fails into triage low grade lesions. HPV DNA test confirms infection by the virus, present in 99% of cases. However, it does not discriminate between transient and persistent infection as it is crucial because it is the persistent infection which progresses to neoplasia. Histological assessment of cervical biopsy that is considered as “gold standard” can be hampered by intra and inter observer variability. A more specific triage marker is required to identify women who would need colposcopy. Hence, p16INK4a has emerged as a new diagnostic and prognostic biomarker. Aims and objectives: This study was conducted to evaluate the utility of staining of p16INK4a on conventional Pap smears and its comparison with corresponding biopsies. Material and Methods: 50 cases of conventional Papanicolaou stained cervical smears cases were randomly selected from the archive of cytopathology laboratory. The cervical smears were re-evaluated for adequacy, preservation of cells, cytomorphology and various lesions were categorized according to The Bethesda system 2001 (TBS) classification. Consecutive such cases were selected for which both cytological and histological material were available. Immunostaining of cervical cytological specimens for p16 was performed using monoclonal murine antibody, clone 16P04, JC2. Ready to use antibody was used for immunostaining as per manufacturer's protocol. Results: Out of the 50 smears of preneoplastic and invasive lesions, ASCUS was seen in 5 cases, LSIL in 10 cases, HSIL in 20 cases, SCC in 20 cases and AGUS in 5 cases. Of the 5 cases of ASCUS, histopathology showed 3 chronic cervicitis and 1 each in CIN-1 and CIN-2. Histopathological diagnosis of 10 cases of LSIL showed 6 CIN-1 and 2 each in CIN-2 and chronic cervicitis. Similarly, for 10 cases of HSIL, 3 were CIN-2, 5 CIN-3 and 2 SCC. All 20 cases of carcinoma showed SCC while 5 cases of AGUS showed 4 chronic cervicitis and one adenocarcinoma. Immunohistochemical staining of p16INK4A showed weak positivity in 3 cases of chronic cervicitis and 4 cases of CIN-1. In CIN-2 cases, 66.67% showed strong positivity, CIN-3 showed 80% while both carcinoma and adenocarcinoma showed 100% strong positivity. The sensitivity of immunohistochemical staining of p16INK4A was 77.5%, specificity was 100%, PPV 100% and NPV 52.6%. The relation between histological and cytological immunostaining of p16INK4A. Conclusion: p16INK4A is a reliable marker for dysplastic squamous and glandular cervical cells both in tissue sections and in cervical smears. p16 immunostaining can be easily performed on CPS, and there is high concordance of positivity on smears and tissue sections.

Introduction: The objective of the present study was to study the utility and the effectiveness of intraoperative ultrasound in neurosurgical procedures and to assess the outcome. Material and Methods: In this prospective study, operative procedures by a single surgeon under intraoperative ultrasound localization for basal ganglia/thalamic haematoma or traumatic brain contusions or brain tumours were included. Ultrasound scanning of the brain was performed before and after the excision of the lesion and during the procedure to verify the extent of removal of the lesion. Results: 74 patients underwent surgery for brain tumor/basal ganglia bleed/head injury with hemorrhagic contusion with the help of intraoperative ultrasound. Gross tumor resection was noted in 25 out of 36 cases of brain tumors (69.44%), complete evacuation of hematoma was noted in 14 out of 34 cases(41.2%) of basal ganglia bleed and in 2 out of 4 cases (50%) of intracerebral contusion. As per Modified Rankin scale (MRS)score, among the brain tumor cases, all patients had fared well in recovery and had better MRS scores except in one patient who expired during postoperative period. Conclusions: IoUS is a widely accessible, cheap, portable and less space occupying and reliable imaging tool to follow and modify the surgical plan in real time, and is more accurate and helpful in complete tumor resection, evacuation of intracerebral bleeds and contusions, and biopsy of deep seated lesions. It is easy and safe to handle with no risk of radiation.

Introduction: Propofol is a short-acting medication that lowers awareness and causes a transient memory loss. It is given intravenously. The aim of this study was to assess the prevalence of various side effects of the use of propofol as an anesthetic in various surgical procedures and to compare their prevalence among adults and children. Materials and Methods: One hundred patients were included in the study, fifty adults and fifty of children, who underwent various types of surgery and received propofol anesthesia, at Pediatrics Hospital, Benghazi Medical Center (BMC) and Al-Hawari hospital, from September to November 2019. Results: The mean age was 6.37 ± 4.18 years in the pediatric group (ranging from 1 to 15 years) and 40.0 ± 17.03 years in the adult group (range from 16 to 97 years). The indication of surgery among the adult group was cholecystectomy (14 patients, 28%), followed by ENT operations (12 patients, 24%), while the indication of surgery among the pediatric group was tonsillectomy (20 patients, 40%), followed by hernia repair (15 patients, 30%). Thirty-five adults (70%) and 40 children (80%) suffered different types of complications during the study. Pain at the site of propofol injection was the most common complication. It was observed in 21 adult patients (42%) and 23 children (46%). Bronchospasm developed among 11 children who underwent tonsillectomy. Low blood pressure was more prevalent among adult patients (14 patients, 28%). An arrhythmia was developed in nine patients (six adults and three children). Two adults and five children experienced delayed recovery from anesthesia. The recovery time was 14.67 ± 8.37 min (5â€"45 min), Conclusion: Burning at site of propofol injection is the most common side effect of propofol anesthesia; other complications need further evaluation by more detailed studies.

Chronic relapsing inflammatory optic neuropathy (CRION), initially described in 2003, is a form of recurrent optic neuritis (ON) that has relatively good response/dependency to steroid treatment. In demyelinating ON, patients present with periorbital ache and pain elicited by eye movement, which usually begins insidiously and worsens, in synchrony with or preceding a reduction in vision, which deteriorates over days. The etiology of CRION is unknown. However, the excellent response to corticosteroids and the need for immunosuppressive therapy to prevent relapse suggests an immunomediated origin.

Recurrent respiratory papillomatosis (RRP) is a benign lesion seen in the respiratory airway caused by human papillomatosis virus (HPV).RRP can affects children to young adults. Most of the childhood RRP occur at birth which contaminated from birth canals of the mother. In adult ages, the infections transmitted via sexual route. The lesions are often seen as exophytic nodules, mostly in the larynx and occasionally at the nasopharynx, tracheobronchial trees and lung parenchyma. This disease is often unpredictable and varies from spontaneous remission to aggressive persistent or recurrence in nature.RRP has chance for malignant transformation to squamous cell carcinoma although it is a rare happening. The diagnosis is confirmed by histopathological study. Presently there is no definite treatment for RRP available. Surgery is the treatment of choice along with several adjuvant therapies available. The aim of this review article is to describe the detail etiology, epidemiology, clinical presentations, investigations and treatment of RRP.

Additive manufacturing (AM) or three-dimensional printing (3DP) is a new technology known for rapid fabrication of customized or finely detailed parts with decreased cost. The technology uses the principle of layer by layer-based manufacturing of parts following the bottom-up approach. In recent years, AM technologies have seen a rapid development in various fields of engineering, medical, and aeronautics. Development in technology and biomaterials has made AM more novel and approachable techniques for complex medical treatments. In the current work, a reflection on the use of AM technology in the field nephrology has been presented. At present, AM technologies are used in conceptualizing and fabricating urological instruments, planning surgeries, and educating the apprentices and patients. The review primarily aimed to present the use of AM for education and surgical planning in nephrology. The study will also discuss the limitation and future scope of AM in the field of nephrology.

Cholesteryl ester storage disease (CESD) in children is a rare anatomo-clinical entity, characterized by a secondary lysosomal accumulation and an autosomal recessive mutation in the LIPA gene, which results from a lysosomal acid lipase (LAL) deficiency. The work of this paper is based on our observation of a 25-month-old infant, who had an abdominal distension with a hepatomegaly of 13 cm. The abdomen X-ray has shown some bilateral adrenal calcifications. The results of the biological assessment : the hepatic check showed a slight cytolysis, triglycerides increased to 5.4 g.l with a reduced rate of high density lipoproteins. The blood smear has shown the presence of intracytoplasmic lipid vacuoles in the lymphocytes, with a positive MGG staining and a negative PAS staining. The activity of the LAL enzyme has decreased to 3.6%. This observation joins the rare pediatric cases of the CESD and highlights the interest in a simply available radiological examination to make a guidance diagnosis of a complex metabolic disorder.

Xanthogranulomatous osteomyelitis (XO) is a type of chronic osteomyelitis characterized by collection of foamy macrophages admixed with mononuclear cells. Xanthogranulomatous inflammation is characterized by the presence of histiocytes, foamy macrophages, activated plasma cells, and presence of suppurative foci and hemorrhage. It has been encountered in various tissues such as gallbladder, kidney, urinary bladder, fallopian tube, ovary, vagina, prostate, testis, epididymis, colon, and appendix. Very rarely, it can affect lungs, brain, or bone. Only three cases of XO have been described previously in the literature till date.
