Diagnostic usefulness of triple biopsies (Skin, Muscle and Nerve) in clinically suspected cases of vasculitis in a tertiary care hospital in Gujarat

Introduction: The term vasculitis refers to a heterogeneous group of diseases, all characterized by inflammation and destruction of blood vessel walls leading to ischemic, thrombotic, and hemorrhagic damage to tissues of central and peripheral nervous system. The main indication for triple biopsy (skin, muscle and nerve) is to rule out peripheral vasculitis neuropathy. However, the drawback is that any systemic inflammatory process may show changes in a skin biopsy and hence these changes need to be interpreted with caution. The aim of this study is to establish the diagnostic yield and the usefulness of the triple biopsies in clinically suspected cases of vasculitis. Material and Methods: The present study was conducted in the Department of General Pathology, SBKS MI & RC, Vadodara over a period of one year (1/1/2022 to 31/12/2022). All the clinically suspected cases of vasculitis received at OPD were included in the study. Any case with either muscle, nerve or skin biopsy reported as inadequate were excluded from the study. Results: On evaluation the usefulness of triple biopsies for vasculitis, we found a very low diagnostic yield with only 3.3% of peripheral nerve biopsy and 0.8% of muscle and nerve biopsy showed definite vasculitis. In case of suspected peripheral/systemic vasculitic neuropathy, nerve biopsy was sufficient in the majority of case and has the diagnostic armamentarium for the evaluation of vasculitis. Conclusion: In conclusion, nerve biopsies provide the best yield for the diagnosis of vasculitis, as opposed to muscle and skin biopsies. The role of triple biopsies as a routine protocol for the evaluation of vasculitis is questionable.

Expression and sensitivity of immunohistochemical markers SMA, Desmin, CD10 for uterine leiomyomas - A tertiary care centre experience

Introduction: Leiomyoma is the most common benign tumor of the uterus which usually presents with menorrhagia, pain in abdomen or both. In extremely rare cases where uterine leiomyoma can be difficult to distinguish from other uterine smooth muscle tumors, immunohistochemistry is used. This study was aimed to study the expression and sensitivity of immunohistochemical markers SMA, Desmin, CD 10 for uterine leiomyomas and to find average number of mitosis in uterine leiomyomas using Ki 67. Materials and methods: The present study was carried out in the Department of Pathology, Dhiraj General Hospital and Smt. Bhikhiben Kanjibhai Shah Medical Institute and Research Centre, Sumandeep Vidyapeeth, Piparia. A total 50 cases of uterine leiomyomas after its histological diagnosis were evaluated with immunohistochemical markers SMA, Desmin, CD 10 and Ki 67. Results: SMA expression was seen in all 50 cases of uterine leiomyomas with strong expression in 44 cases (88%). Strong SMA expression was seen more in usual leiomyomas as compared to leiomyomas with secondary changes. Desmin expression was also seen in all the 50 cases of uterine leiomyomas with moderate expression in 26 cases (52%). Weak CD 10 expression was seen in 15 cases of uterine leiomyomas (30%). Ki 67 was expressed very focally in only 3 cases of leiomyomas with mean value of only 0.3% tumor cells. Conclusions: Leimyomas was most frequently seen in the women in 4th decade. The most common clinical presentation was menorrhagia. SMA and Desmin expression was seen in all the cases with strong and moderate immunoreactivity respectively. SMA expression was found to be more specific than Desmin in uterine leiomyoma. Weak CD 10 and focal Ki 67 were expressed only in few cases and were found to be insignificant.

Laparoscopic repair of post hysterectomy ureterovaginal fistula

The fistulas, following gynecologic, surgeries are not uncommon. Hysterectomy is one of the most common causes of lower urinary tract fistula in pelvic surgery. Higher incidences are associated with laparoscopic hysterectomy as compared to vaginal or abdominal hysterectomy. Early identification and management of ureterovaginal fistula (UVF) are of utmost importance. The laparoscopic approach in the management of UVF is preferred over open surgery as it reduces pain, hospital stay, and morbidity. However, the laparoscopic approach needs higher surgical dexterity, sound knowledge of pelvic anatomy, and has a higher learning curve. One such approach is discussed here.

Age - Does it really count? A study of the Perioperative Morbidity and Long-Term Outcome in Patients Above 70 Years of Age Undergoing Spine surgery for Lumbar Degenerative Disorders / Idade - Deve ser levada em conta? Estudo da morbidade perioperatória e a evolução no longo prazo dos pacientes acima de 70 anos submetidos à cirurgia da coluna vertebral, devido a doenças degenerativas lombares

Abstract Objective To assess the long-term outcome and perioperative morbidity in spine surgeries for lumbar degenerative disorders and, thereby, to evaluate the safety of surgery in the aging population. Methods Retrospective study of patients aged > 70 years, operated for degenerative lumbar disorders between 2011 and 2015. We evaluated patient demographic, clinical and surgical data; comorbidities, perioperative complications, pre & postoperative pain scores and Oswestry disability index (ODI) scores, patient satisfaction and overall mortality. Results A total of 103 patients (Males: Females55:48) with mean age 74.6 years (70-85yrs) were studied. 60 patients (58.2%) had decompression alone, while 43 (41.8%) had decompression & fusion. Mean hospital stay was 5.7days. Mean follow-up was 47.6months (24-73mnths). Patients reported significant improvement in backpain (Numerical pain score 7.7 vs 1.6; p < 0.001), leg pain (Numerical pain score 7.4 vs 1.7; p < 0.001), disability (ODI 82.3 vs 19.1; p < 0.001) and walking distance (p < 0.001). 76% patients were satisfied with the results at the time of final follow-up. 26 patients (25.24%) had perioperative complications which were all minor, without mortality. Most common intraoperative & postoperative complications were dural tear (6.79%) & urinary tract infection (6.79%) respectively. Conclusions With meticulous perioperative care lumbar spine surgery is safe and effective in elderly population. Patients had longer mean hospital stay in view of the gradual and comprehensive rehabilitation program. Presence of comorbidities or minor perioperative complications did not increase the overall morbidity or affect the clinical outcomes of surgery in our study.

Resumo Objetivos Avaliar o resultado no longo prazo e a morbidade perioperatória em cirurgias da coluna vertebral, devido a doenças lombares degenerativas e, assim, avaliar a segurança da cirurgia na população idosa. Métodos Estudo retrospectivo de pacientes com idade superior a 70 anos, submetidos à cirurgia em virtude de distúrbios lombares degenerativos, entre 2011 e 2015. Foram avaliados os dados demográficos, clínicos e cirúrgicos dos pacientes; comorbidades; complicações perioperatórias; escores de dor no pré e no pós-operatório; índice de incapacidade de Oswestry (ODI, na sigla em inglês); satisfação do paciente e a mortalidade geral. Resultados Foram estudados 103 pacientes (homens:mulheres, 55:48) com idade média de 74,6 anos (70 a 85 anos). 60 pacientes (58,2%) apresentaram somente descompressão, enquanto 43 (41,8%) apresentaram descompressão e fusão. O tempo médio de internação foi de 5,7 dias. O tempo médio de acompanhamento foi de 47,6 meses (24-73 meses). Os pacientes relataram melhora significativa da dor nas costas (pontuação numérica da dor 7,7 versus 1,6; p < 0,001), dor nas pernas (pontuação numérica da dor 7,4 versus 1,7; p < 0,001), incapacidade (ODI 82,3 versus 19,1; p < 0,001) e distância percorrida a pé (p < 0,001). Um total de 76% dos pacientes estavam satisfeitos com os resultados no momento do acompanhamento final. 26 pacientes (25,24%) apresentaram complicações perioperatórias, todas sem relevância e sem mortalidade. As complicações intra e pós-operatórias mais comuns foram ruptura dural (6,79%) e infecção do trato urinário (6,79%), respectivamente. Conclusões Com meticulosos cuidados perioperatórios, a cirurgia da coluna lombar é segura e eficaz na população idosa. Os pacientes tiveram um maior tempo médio de internação hospitalar, em virtude do programa de reabilitação gradual e abrangente. A presença de comorbidades ou complicações perioperatórias sem relevância, não aumentou a morbidade geral, nem afetou os resultados clínicos da cirurgia em nosso estudo.

Comparative evaluation of sealing ability of calcium sulfate with self-etch adhesive, mineral trioxide aggregate plus, and bone cement as furcal perforation repair materials: An In vitro dye extraction study

Aim: The aim of this study was to determine the sealing ability of three different materials mineral trioxide aggregate (MTA) Plus, bone cement, and calcium sulfate with self-etch adhesive (SEA) for the repair of furcal perforation, using dye extraction method. Materials and Methods: Forty-eight extracted human permanent first and second molars were included and randomly divided into four groups: Group 1, n = 12, negative control, perforation not repaired with any material, Group 2, n = 12, perforation repair material used, MTA Plus, Group 3, n = 12, perforation repair material used, calcium sulfate with SEA, Group 4, n = 12, perforation repair material used, bone cement. The teeth were then coated with two coats of clear nail varnish immersed in methylene blue dye for 24 h, kept in 65% concentrated nitric acid for 3 days. Dye leakage was measured with the dye extraction method using a spectrophotometer at 550 nm. Results: The negative control showed the highest mean values of dye absorbance (1.45). Bone cement (0.94) came second. Calcium sulfate with SEA (0.58) and MTA Plus (0.32) had no significant difference in their dye absorbance values. Conclusion: Within the limitations of the study, MTA Plus showed the least microleakage followed by calcium sulfate with SEA which has shown promising results and can be used as an alternative followed by bone cement which showed the highest microleakage.

Uterine Transplantation: An Option beyond Surrogacy.

Over the years, a lot has developed in the field of infertility and artificial reproductive techniques worldwide, but the uterine factor infertility still remains an unresolved issue in reproductive medicine. Absolute uterine factor infertility is synonymous with congenital absence of uterus or a physiologically nonfunctioning uterus. Very few options including surrogacy and adoption are available for these patients. Both surrogacy and adoption are associated with legal, ethical, financial, religious, and psychological issues. For some of these patients, uterine transplant could be a viable option in future. However, the ability of uterus to carry the pregnancy to the period of viability and the effect of immunosuppressant on the fetus make the uterine transplant a more complex operation than any other transplants. From the earliest uterine transplant tried in 1931 in Germany to the first successful child birth following transplant in Sweden in 2014, uterine transplantation has come a long way. Among the countries that have tried this till now, Sweden has reported five cases of successful births posttransplant. Behind these successful cases, there is dedication and perseverance of few individuals who continued their efforts in spite of repeated failures. At the moment, the uterine transplant can be considered experimental at the best. However, considering the large number of hysterectomies done all over the world and uteruses available for transplantation, uterine transplant has potential to surpass, in numbers, the other transplant in near future.

Atypical histological features of ulcerative colitis.

Introduction: The diagnosis of ulcerative colitis is based on combination of clinical, endoscopic and pathological findings. However cases have been reported showing atypical endoscopic and histological features in ulcerative colitis. Hence the objective of this study was to determine the atypical features of new onset ulcerative colitis in adult population. Methods: A total 110 newly diagnosed cases of ulcerative colitis were enrolled in the study over a period of five years. The diagnosis of ulcerative colitis was made by correlating clinical, endoscopic and histological features. Biopsies from representative areas were processed routinely. Endoscopic and histological evaluation was carried out for atypical features. Results: Majority of the patients (75.4%) were between 21-50 years of age with male to female ratio of 2.2:1. A significant number of patients showed atypical endoscopic findings in the form of rectal sparing in 12 (10.9%) and skip lesions in 24 (21.8%) patients. Atypical features noted on histology included normal surface epithelium in 8 (7.3%), predominant polymorphs in 42 (38%), predominant eosinophils in 7 (6.3%), normal crypt architecture in 1 (0.9%) and well preserved goblet cells in 30 (28%) cases. Conclusion: A significant number of patients with new onset ulcerative colitis showed atypical pattern of disease endoscopically as well as histologically. Pathologists should be aware of these atypical findings in cases of ulcerative colitis so as to avoid misdiagnosis.

Adjuvant role of vitamin B analogue (sulbutiamine) with anti-infective treatment in infection associated asthenia.

AIMS OF THE STUDY: Asthenic symptoms such as weakness accompany illness. This study investigates whether the centrally acting cholinergic agent, vitamin B analogue (sulbutiamine), is effective and acceptable in relieving these symptoms in infectious disease when combined with specific anti-infective treatment. METHODOLOGY: In a prospective uncontrolled, non-randomised, commercial, observational study, 1772 patients with an infectious disease and asthenic symptoms, drawn from the practice of 350 randomly selected physicians throughout India, received vitamin B analogue (sulbutiamine) in addition to specific anti-infective treatment for 15 days. The primary outcome variable was complete resolution of asthenic symptoms with treatment. RESULTS: The number (%, 95% confidence interval) of patients with complete resolution of all asthenic symptoms was 916 (51.7, 49.4-54). In the remaining patients, severe asthenia was reduced but persisted in 11 (0.6, 0-26); and moderate asthenia in 94 (5.3, 0-17.6). The response was greater in patients with acute infection and symptoms more related to cerebral function. Side effects occurred in 10 (0.6%), patients and well being improved significantly. CONCLUSIONS: Vitamin B analogue (sulbutiamine) may be a useful adjunct to specific anti-infective treatment.
