Abstract
Artificial intelligence (AI) language generation models, such as ChatGPT, have the potential to revolutionize the field of medical writing and other natural language processing (NLP) tasks. It is crucial to consider the ethical concerns that come with their use. These include bias, misinformation, privacy, lack of transparency, job displacement, stifling creativity, plagiarism, authorship, and dependence. Therefore, it is essential to develop strategies to understand and address these concerns. Important techniques include common bias and misinformation detection, ensuring privacy, providing transparency, and being mindful of the impact on employment. The AI-generated text must be critically reviewed by medical experts to validate the output generated by these models before being used in any clinical or medical context. By considering these ethical concerns and taking appropriate measures, we can ensure that the benefits of these powerful tools are maximized while minimizing any potential harm. This article focuses on the implications of AI assistants in medical writing and hopes to provide insight into the perceived rapid rate of technological progression from a historical and ethical perspective.

Evaluating Patterns of Injectate Spread After Rectus Sheath Block: A Cadaveric Dissection Study. Cureus 2023; 15:e34142. [PMID: 36843817 PMCID: PMC9949744 DOI: 10.7759/cureus.34142] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 01/24/2023] [Indexed: 01/26/2023] Open
Abstract
INTRODUCTION This cadaveric dye study assesses the effect of volume and number of injections on the spread of solution after ultrasound-guided rectus sheath injections. In addition, this study evaluates the impact of the arcuate line on solution spread. MATERIALS AND METHODS Ultrasound-guided rectus sheath injections were performed on seven cadavers on both sides of the abdomen, for a total of 14 injections. Three cadavers received one injection of 30 mL of a solution consisting of bupivacaine and methylene blue at the level of the umbilicus. Four cadavers received two injections of 15 mL of the same solution, one midway between the xiphoid process and umbilicus and one midway between the umbilicus and pubis. RESULTS Six cadavers were successfully dissected and analyzed for a total of 12 injections, while one cadaver was excluded due to poor tissue quality that was inadequate for dissection and analysis. There was a significant spread of solution with all injections caudally to the pubis without limitation by the arcuate line. However, a single 30 mL injection showed inconsistent spread to the subcostal margin in four of six injections, including in a cadaver with an ostomy. A double injection of 15 mL showed consistent spread from xiphoid to pubis in five of six injections, except in a cadaver with a hernia. CONCLUSIONS Injections deep to the rectus abdominis muscle, using the same technique as an ultrasound-guided rectus sheath block, achieve spread along a large and continuous fascial plane without limitation by the arcuate line and may provide coverage of the entire anterior abdomen. A large volume is necessary for complete coverage and spread is improved with multiple injections. We suggest that two injections with a total volume of at least 30 mL per side may be needed to achieve adequate coverage in the absence of preexisting abdominal abnormalities.

Low Dose Aspirin in high-risk pregnancies: The volatile effect of acetylsalicylic acid on the inhibition of platelets uncovered by G. Born's light transmission aggregometry. J Reprod Immunol 2021; 145:103320. [PMID: 33962140 DOI: 10.1016/j.jri.2021.103320] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/10/2020] [Revised: 02/15/2021] [Accepted: 03/31/2021] [Indexed: 11/24/2022]
Abstract
Preeclampsia still represents a life-threatening pregnancy complication, associated with severe maternal and neonatal morbidity and mortality. Low-dose Aspirin is advised to avoid preeclampsia in high-risk pregnancies worldwide. As Aspirin does not cover all women at risk, the prescription raises questions concerning optimal target population, dosage, and onset of therapy. The aim of this study was to test platelet responsiveness on Aspirin by optical aggegrometry, to gain robust biochemically assessment data of Aspirin in an obstetric cohort. 248 women at high risk for development of preeclampsia were included in the study. Aspirin-prophylaxis was administered either in 100 mg (n = 229) or 150 mg (n = 90) daily. Dosing of 100 mg Aspirin was maintained if testing revealed a sufficient platelet inhibition. If platelet inhibition was insufficient, dosage was increased to 150 mg Aspirin and re-testing was advised. 91 patients (91/229 = 39.7%) presented a sufficient inhibitory Aspirin effect at a dosage of 100 mg, but in 138 patients LTA showed an inadequate Aspirin response (138/229 = 60.3%). In 19 women 150 mg Aspirin was administered as starting dose due to new recommendations. Of all women at 150 mg Aspirin 64 did not properly respond (35.4%). The overall rate of sufficient responding women regardless the Aspirin dose was 64.6%. This study demonstrates still an insufficient inhibition of platelet aggregation in about 1/3 of women even with a dosage of 150 mg Aspirin daily, who might potentially benefit from further increase. These data show, that there is a need for further research to allow a personalized approach for individualized Aspirin therapy, maximizing the preventive benefit for mother and child.

Abstract
BACKGROUND Conventionally, it is well accepted that the intestinal obstructions in children, especially gastric outlet obstruction are associated with significant metabolic derangement which has impact on its outcome. The study aimed to compare the metabolic profile and treatment outcome of pre- and post-ampullary gastrointestinal obstruction in children at a tertiary care setting. MATERIALS AND METHODS A prospective observational study was conducted on 30 children with intestinal obstruction and categorised into Group 1 (pre-ampullary, n = 11) and Group 2 (post-ampullary, n = 19) as per their anatomical site of pathology. Patients were evaluated at both pre- and post-operative period (Day 1 and 10) with haematological, biochemical and blood gas. The pre- and post-operative metabolic profile, resuscitative time and outcome were compared in two groups. RESULTS Except mild leucocytosis (Group II > I), rest of the pre-operative and post-operative haematological parameters were within normal range and statistically comparable among groups. Although the pre-operative sodium values were within the normal limit in both groups, it was relatively higher in Group I (Group I = 137.82 ± 4.238 vs. Group II = 134.26 ± 4.653), (P = 0.04). The mean bicarbonate values were within the normal limit in both groups (22.49 and 19.34), but the difference was statistically significant (P = 0.031). Mean partial pressure of carbon dioxide level was higher than normal range in Group I (38.464 ± 20.6493) but was comparable with Group II (P = 0.15). The time required for pre-operative resuscitation was 16.6 versus 24.87 h in Group I versus Group II (P = 0.02). In Group I, all children were improved, whereas four children expired in Group II. CONCLUSION Metabolic profile in both pre- and post-ampullary intestinal obstruction was found to be normal in majority of the scenario. Children with post-ampullary obstruction need extensive pre-operative resuscitation and have relatively poor outcome.

Abstract
OBJECTIVE Experimental evidence suggests that changes in the fetal myocardium result from intrauterine effects of maternal diabetes mellitus and obesity. The aim of this study was to assess fetal cardiac function using two-dimensional speckle-tracking echocardiography to determine the effects of maternal diabetes and obesity on the fetal myocardium. METHODS Comparative cross-sectional evaluation of myocardial function in fetuses of mothers with diabetes mellitus (FDM) or obesity (FO) and normal gestational age-matched control fetuses (FC) was performed using two-dimensional speckle-tracking echocardiography at two centers. RESULTS In total, 178 fetuses (82 FDM, 26 FO and 70 FC) met the enrolment criteria. Mean gestational age at assessment was similar among groups: 25.3 ± 5.1 weeks for FDM, 25.0 ± 4.6 weeks for FO and 25.1 ± 4.9 weeks for FC. Mean maternal body mass index was significantly higher in FDM and FO groups compared with the FC group. Statistically significant differences in fetal cardiac function were detected between FDM and FC for global longitudinal strain (mean ± SD, -21.4 ± 6.5% vs -27.0 ± 5.2%; P < 0.001), global circumferential strain (mean ± SD, -22.6 ± 6.5% vs -26.2 ± 6.8%; P = 0.002), average longitudinal systolic strain rate (median, -1.4 (interquartile range (IQR), -1.7 to -1.1)/s vs -1.6 (IQR, -2.0 to -1.4)/s; P = 0.001) and average circumferential systolic strain rate (median, -1.4 (IQR, -1.9 to -1.1)/s vs -1.6 (IQR, -2.1 to -1.3)/s; P = 0.006). Cases of non-obese FDM also had abnormal strain parameters compared with FC. Global longitudinal strain (mean ± SD, -21.1 ± 7.5%) and average circumferential systolic strain rate (median, -1.3 (IQR, -1.8 to -1.1)/s) were significantly lower in FO compared with FC. CONCLUSIONS Unfavorable changes occur in the fetal myocardium in response to both maternal diabetes mellitus and obesity. The long-term prognostic implications of these changes require further study.

Abstract
AIM To determine the usefulness of infra-umbilical mini-vesicostomy in infants with posterior urethral valves (PUV), in developing countries. This new technique facilitates clean intermittent catheterization (CIC) and overnight bladder drainage, which have been effectively used for the treatment of valve bladders in the developed world. METHODS A retrospective analysis of the records of three infants who underwent a mini-vesicostomy between 2005-2009 was done. All were put on CIC in the neonatal period. Monitoring of renal parameters, bladder function and structural changes in the bladder was done before and after 4 years of CIC. RESULTS All three showed a decrease in upper tract dilatation, improvement in cortical function and improvement of bladder compliance at the end of 4 years. Two patients are on CIC through vesicostomy and can pass a good stream of urine per urethraly, and in one the vesicostomy has been closed. CONCLUSION Mini-vesicostomy is a useful option to allow CIC on a long-term basis in children with PUV. There were no complications with this technique in this small group of patients, and it has been well accepted by their families.

Abstract
Split notochord syndrome is a rare congenital malformation that results in spinal anomalies associated with anomalies of the gastrointestinal tract and central nervous system. This report presents an infrequently described variant of this syndrome. A 9-month-old female presented with a dorsal midline mass since birth which was partially covered by skin, and part of the lesion gave a gross appearance of intestinal mucosa. MRI was suggestive of partial sacral agenesis with spinal dysraphism with tethered cord. Excision of the mass with repair of the spinal defect was done. Histopathology confirmed the presence of gastrointestinal mucosa.

Abstract
Ventriculo-peritoneal (VP) shunting used in the treatment for hydrocephalus is associated with several complications. Mechanical failure of shunt is the commonest complication of all. Visceral/bowel perforation is an unusual but serious complication of VP shunting. This article reports our experience in the management of ten children who had VP Shunt catheter protrusion from anus. This is a retrospective study of ten patients who had VP shunt catheter protrusion from anus, admitted in the department of paediatric surgery between Jan 1996 and Dec 2005. The records of above ten cases were reviewed for their clinical presentation and management, etc. We had performed 398 VP shunt operations in the last 10 years. Two hundred and seventy one (68.09%) VP Shunts were done for congenital hydrocephalus of which 164 were done in infancy/neonatal period and 107 VP shunts were done in the age group of >1-12 years. One hundred and twenty-seven (31.90%) VP shunt operations were done for patients who had hydrocephalus as a complication following tubercular meningitis (TBM). Out of 398 VP shunts, ten patients (2.51%) had protrusion of the distal end of peritoneal catheter from anus without causing/leading to peritonitis. We observed a 08.29% mortality of all VP shunt operations. Protrusion of VP shunt catheter per rectum can occur without producing peritonitis. Formal exploration and localization of entry of VP shunt catheter in bowel is not mandatory. Mini laparotomy and revision of peritoneal part of shunt can be done if there is no shunt infection.

Abstract
Literate but unskilled--and largely female--labor has thus far fueled the tremendous increase in manufactured exports of garments and microelectronic products from the Third World to the industrially advanced economies of the North. The future growth of these sectors, however, may require literate and skilled workers--a category in which women are woefully under-represented, especially in the Third World. In the case of the garment industry, defensive innovation in the industrially advanced countries, including automation and flexible management, has initiated a relocation of jobs to these countries or to offshore locations geographically close to their markets. Automated garment production in these countries requires fewer but computer-literate workers. In the case of microelectronics, development policies of East Asian countries and the competitive pressures on start-up companies in the North have led to an increased demand for computer-literate, skilled technicians over the unskilled and overwhelmingly female workforce of manual-assembly workers. Women's continued employment and advancement in these industries globally will depend upon their acquisition of new technical skills. The ratification by the 1995 international women's conference at Beijing of the demand for better access to education and skills training for women, especially in the Third World, is a step in the right direction.

Abstract
PURPOSE To describe a morphologic variant of the multiple evanescent white-dot syndrome that can mimic other conditions. METHODS We examined three patients with severe cases of unilateral multiple evanescent white-dot syndrome characterized by an atypical progressive circumpapillary discoloration of the fundus. RESULTS The confluent circumpapillary lesion progressed toward or beyond the equator of the fundus, raising initial concern of a viral retinitis. However, pinpoint dots at the leading edge evolved into the typical wreath-like spots of multiple evanescent white-dot syndrome, which then coalesced into the advancing edge of a geographic retinitis or retinal pigment epitheliitis, before spontaneous resolution. CONCLUSION Progressive geographic circumpapillary discoloration, appearing as a giant white spot, occurs rarely in severe cases of multiple evanescent white-dot syndrome. The distinctive appearance may suggest a disorder other than multiple evanescent white-dot syndrome, which can make initial diagnosis more difficult and lead to unnecessary or inappropriate testing and treatment.

Abstract
Patients with malignant bone tumours often come at a very late stage of disease to Medical Colleges. Because of their high mortality rate, accurate & quick diagnosis of these lesions become essential, inspite of clinical, radiological and histopathological assessments. A simple, inexpensive, safe & least traumatic technique-fine needle aspiration cytology (FNAC) in diagnosis of 55 malignant bone tumours was carried out. Specific tumour types metastatic tumour (12), Giant cell tumour (12), Ewing's sarcoma (10), Osteosarcoma (7), Multiple myeloma (7), Chordoma (3), Chondrosarcoma (3) and Fibrosarcoma (1) could be ascertained in 87.2% whereas malignant tumour was suggested in 94.5% (52 cases).

Abstract
Patients with human immunodeficiency virus infection are predisposed to fungal, parasitic, and viral infections. Bacterial infection can also be seen, although ocular bacterial infections have not been reported in patients with acquired immunodeficiency syndrome until recently. We present two cases of Pseudomonas corneoscleritis and one case of Pseudomonas keratitis in patients with human immunodeficiency virus infection that failed to respond to antibiotic treatment. Predisposing factors included extended-wear soft contact lens use in one patient and exposure secondary to Bell's palsy in another patient. All three patients had neutropenia that may have contributed to their poor response to treatment. Enucleation was required to treat two patients with overwhelming infection. Enucleation has been rarely required for treatment of corneoscleritis in immunocompetent patients treated at our institution. Pseudomonas keratitis in human immunodeficiency virus-infected patients represents a serious ocular infection requiring early diagnosis and aggressive treatment.

Abstract
A 37-year-old male laboratory technician who sustained a cutaneous penetrating wound from a rhesus monkey developed a progressive ascending encephalomyelitis due to culture-proven herpes B virus (Herpesvirus simiae) infection. He died 6 weeks after his injury despite acyclovir and ganciclovir treatment that was initiated after central nervous system symptoms developed. Histopathological examination of the patient's left eye revealed a multifocal necrotizing retinitis associated with a vitritis, optic neuritis, and prominent panuveitis. Herpes-type virus was identified in the involved retina by electron microscopy. Postmortem vitreous cultures taken from both eyes and retinal cultures taken from the right eye were positive for herpes B virus. Herpes B virus produces infection and destruction of retinal tissues similar to other herpesviruses. To our knowledge, this case represents the first histopathologic demonstration of herpes B virus infection in a human eye.

Abstract
The presence of background and preproliferative retinopathy in 70 patients with type I diabetes was correlated with their pubertal development. Pubertal status was assessed by pediatricians using the sexual maturity ratings of Tanner. In young diabetics with comparable disease duration (5 to 10 years), postpubertal children had a greater prevalence of retinopathy than those who were not sexually mature. After adjusting for duration of diabetes and sex, the relative odds of having retinopathy in the postpubescent group relative to the prepubescent or pubescent groups was 4.8 (95% confidence interval: 1.5 to 15.3). This study suggests that minimal retinopathy in children is not rare and that postpubescent children have a greater prevalence of diabetic retinopathy than do prepubescent children with similar diabetes duration.

Abstract
Surgical treatment of colon and rectal trauma continues to challenge physicians. Injuries to a colon or rectum filled with feces results in subsequent peritoneal contamination which will lead to severe septic complications unless dealt with promptly and correctly. The authors have reviewed the records of 242 patients with colon and rectal trauma operated on at the Cook County Trauma Unit from July 1, 1973 to December 31, 1983, to evaluate treatment results. The mechanism of trauma was penetrating in 233 of 242 patients. Most, if not all, colonic lesions were treated with either exteriorization, resection and no anastomosis, or closure and proximal colostomy. Mortality related to colonic injury was 2.5 percent. Morbidity related to colonic injury included wound infection, 6.3 percent; abscess, 2.5 percent; other, 3.3 percent. Despite the severity of the trauma, adherence to conservative principles of "no anastomosis" in the overwhelming majority of cases has resulted in low morbidity and mortality.

Abstract
Beliefs and practices of 100 urban mothers regarding "hot" and "cold" foods during four common childhood illnesses were determined by using a pretested, partly structured interview schedule. Egg, by 60% of mothers, mango by 52%, lentils by 49%, jaggery by 46% were considered "hot" properties. "Hot" foods were preferred and "cold" foods restricted in the treatment of cough and cold and illnesses with rash. In diarrhoea, "cold" foods were preferred and "hot" foods restricted. The knowledge that many food combinations and certain procedures are believed to change the properties of common food may be utilized in promoting the consumption of nutritionally balanced diets. Introduction of culturally acceptable education in nutrition which incorporates the above knowledge is likely to help in the prevention of protein-energy malnutrition and to increase parental co-operation during therapy.
