An effective regimen for early medical abortion: a report of 2000 consecutive cases

A combination of the anti-progesterone mifepristone and gemeprostprovides an effective non-surgical method for the inductionof abortion at gestations up to 63 days, achieving completeabortion rates of over 95%. We report our experience with analternate regimen, comprising a reduced dose of mifepristonein combination with vaginal misoprostol. A consecutive seriesof 2000 women requesting early medical abortion at gestationsup to 63 days was studied retrospectively. Each woman receivedmifepristone 200 mg orally, followed 36–48 h later bymisoprostol 800 µg vaginally. Of the 2000 women, 39 (2.0%)aborted completely following administration of mifepristonealone and a further 1912 experienced complete abortion followingadministration of misoprostol (a complete abortion rate of 97.5%).Surgical intervention was required in 49 women (2.5%): for incompleteabortion in 27 (1.4%), for missed abortion in seven (0.4%),for continuing pregnancy in 11 (0.6%) and to exclude ectopicpregnancy in four (0.2%). The surgical intervention rate wassignificantly higher among women at gestations 49 days thanamong those at 49 days (3.3 versus 1.5%, P = 0.0193). The regimenappears as effective, in terms of high complete abortion rateand low continuing pregnancy rate, as any published alternative.This regimen has the benefit of being less costly as the doseof mifepristone is 67% lower and misoprostol is substantiallyless expensive than gemeprost. Additionally, misoprostol doesnot require special transport or storage requirements. As such,the combination of mifepristone and gemeprost.     

Response of a wild type and a non-nitrogen-fixing mutant of Anabaena doliolum towards different amino acids

The effects of various amino acids on growth and heterocyst differentiation have been studied on wild type and a heterocystous, non-nitrogen-fixing (het⁺ nif^?) mutant of Anabaena doliolum. Glutamine, arginine and asparagine showed maximum stimulation of growth. Serine, proline and alanine elicited slight stimulation of growth of wild type but failed to show any stimulatory effect on mutant strain. Valine, glutamic acid, iso-leucine and leucine at a concentration of as low as 0.1 mM were inhibitory to growth of parent type. Methionine, aspartic acid, threonine, cysteine, and tryptophan did not affect growth at concentrations lower than 0.5 mM. But at 1 mM, these amino acids were inhibitory. In addition to the stimulatory effects of glutamine, arginine and asparagine, the heterocyst frequency was also repressed by these amino acids. Glutamine and arginine at 2 mM completely repressed heterocyst differentiation in the mutant strain; however, other amino acids failed to repress the differentiation of heterocysts. Our results suggest that glutamine and arginine are utilized as nitrogen sources. This is strongly supported from the data of growth and heterocyst differentiation of mutant strain, where at least with glutamine there is good growth without heterocyst formation. Studies with glutamine and arginine on other N₂-fixing blue-green lagae may reveal the regulation of the heterocyst-nitrogenase sub-system.     

Pitfalls in the diagnosis of epithelioid sarcoma presenting in an unusual site: a case report

The cytologic appearance of epithelioid sarcoma in fine-needle aspiration biopsy cytology (FNABC) smears has not been extensively described. We report a case of epithelioid sarcoma in a 55-year-old male who presented with nodular swellings in the abdominal wall and scrotum. The scrotal swelling was subsequently demonstrated to arise from the vas deferens. We highlight the cytomorphologic, immunocytochemical, and histopathologic features of this rare lesion in an unusual site, with particular emphasis on the dilemma encountered in the cytodiagnosis of this lesion.     

Diagnostic value of routine semen analysis in clinical andrology

Infertility is a major health issue affecting over 48.5 million couples around the world, with the male factor accounting for about 50% of the cases. The conventional semen analysis recommended by the World Health Organization (WHO) is the cornerstone in the evaluation of male fertility status. It includes macroscopic and microscopic evaluation of the ejaculate, which reflects the production of spermatozoa in the testes, the patency of the duct system and the glandular secretory activity. Evaluation of seminal fructose, sperm vitality and leucocytes (Endtz test) are useful adjuncts to semen analysis that provide information on specific clinical conditions. Though several computer-assisted sperm analysis (CASA) systems have been developed, conventional methods for semen analysis are still widely accepted in clinical practice. This review summarises the conventional techniques used in routine semen analysis and their diagnostic value in clinical andrology.     

Protein profiling in unlocking the basis of varicocele-associated infertility

Varicocele is one of the major causes of male infertility and has a negative impact on spermatogenesis. The conventional semen analysis does not reveal the underlying subcellular mechanisms associated with defects in spermatozoa. Proteomics and bioinformatics analysis can be used to identify the molecular aetiologies associated with poor semen quality in varicocele patients. Mitochondrial dysfunction has been identified as the main factor affecting normal physiological functions of spermatozoa. This article discusses the proteomic studies of spermatozoa and seminal plasma in varicocele patients. Proteomics can identify potential spermatozoa and seminal plasma biomarkers in varicocele-mediated male infertility. In future, these protein biomarkers can be useful in the development of noninvasive diagnostic and therapeutic strategies for varicocele patients.     

Endocrine contribution to the sexual dysfunction in patients with advanced chronic kidney disease and the role of hyperprolactinemia

In this study, we investigated the prevalence of sexual dysfunction among males with advanced chronic kidney disease and the effect of treating hyperprolactinemia among these patients. In this prospective study, patients were assessed with history, physical examination, hormonal assessment, and two questionnaires, IIEF and AIPE. Patients with hyperprolactinemia received treatment with cabergoline 0.5 mg once per week for 6 months and were re-evaluated. A total of 102 patients were included in this study, 75 (73.53%) were on hemodialysis, 13 (12.75%) on peritoneal dialysis and 14 (13.73%) on medical treatment alone. Ninety (88.24%) patients had premature ejaculation, 85 (83.33%) had anything from mild-to-moderate-to-severe erectile dysfunction. The incidence of hypogonadism and hyperprolactinemia was 34.4%. Patients treated with cabergoline (n = 26) showed a significant increase in LH levels (p = .003) and a significant decrease in prolactin levels (p = .003). Testosterone levels and the incidence of erectile dysfunction or premature ejaculation did not improve significantly. There is a high incidence of sexual dysfunction among patients. Treatment of hyperprolactinemia is effective in correcting prolactin levels, but does not improve erectile dysfunction or premature ejaculation. Therefore, treating hyperprolactinemia is not an overall effective treatment for erectile dysfunction in these patients.     

Covid-19 Pandemic: Resumption of Orthopedic Care and Medical Education

Covid-19 is a respiratory disease caused by coronavirus 2 (SARS-CoV-2) first identified in Wuhan, China (December 2019). The disease rapidly crossed the barrier of countries, continents and spread globally. Non-pharmaceutical measures such as social distancing, face mask, frequent hand washing and use of sanitizer remained the best available option to prevent the spread of disease. OPD, IPD admissions, elective O. Ts were curtailed. Orthopedic care was only limited to emergency and semi-urgent procedures like necrotizing fasciitis, open fracture, and compartment syndrome. These measures were taken to preserve infrastructure and manpower to manage covid-19 pandemic. The children were thought to have a low susceptibility to covid-19 as compared to an adult. Deferring the patient during pandemic has led to high orthopedic disease burden, morbidity and disease-related sequelae, hence elective care must be resumed with modified hospital infrastructure. Resumption of elective/emergent orthopedic care should be slow, phasic and strategic, much similar to unlocking. Cases must be stratified depending on covid status and severity. Dedicated O.Ts with neutral/negative pressure and HEPA filter for covid positive and suspected patients are to be used. All symptomatic and suspected patients should be investigated for covid-19 by RT-PCR, blood counts and CT scan. Regional anaesthesia should be preferred to General anaesthesia. Power drill/saw/burr/pulse lavage should be minimized to avoid aerosol generation. Postoperatively continuous surveillance and monitoring to be done for covid related symptoms. Medical institutes rapidly shifted to the online mode of education. Blended learning (virtual & physical) and imparting skills have to be continued in post covid phase with equitable distribution of teaching hours to students of different years.

Anhidrotic ectodermal dysplasia presenting as nasal myiasis

An interesting case of anhidrotic Ectoderml Dysplasia (A.E.D.) which came with epistaxix, headache and maggots in nose is presented. Histopathology of forearm shin, scalp and Exercise test helped to confirm the diagnosis, AED is an X-linked recessive condition and has no cure but symptomatic treatment along with heat protection and protection of eyes especially in summer season has a role to play in the management of these cases.     

Effect of adeno-tonsilectomy on hearing threshold and middle ear pressure

Out of 50 children (100 ears) undergoing adeno-tonsillectomy, 34 ears had hearing threshold 20–50 dB (20dB is normal) and 32 ears showed negative middle ear pressure of 100 to 400 mmH₂O (100 mmH₂O is normal). Post-operatively only 7 ears had hearing threshold of 20–30 dB and negative middle ear pressure of 100 to 200 mmH₂O. Thus adenoidectomy improves eustachian tube functions.
