Abstract

Aim:
The aim of this study is to report our experience in the treatment of congenital buried penis using a simplified technique of retrograde progression of inner preputial skin for reconstruction and overcome skin shortage.

Methods:
This is a retrospective multi-institutional study conducted in the Department of Pediatric Surgery, I Q City Medical College and Hospital, Durgapur, West Bengal, India, and the Department of Paediatric Surgery, Rajiv Gandhi Super Specialty Hospital/Raichur Institute of Medical Sciences, Raichur, Karnataka, India, over a period of 3 years (from March 2019 to February 2022). A total of 14 cases of primary congenital buried penis were operated in the specified period. Age of the patients ranged between 8 months and 9 years. Retrograde progression of the inner preputial skin to provide coverage to the dorsal aspect of penile shaft and ventral transposition of the dorsal penile skin to cover the ventral penile shaft was used as a standard procedure for skin coverage.

Results:
All patients had good-to-excellent outcomes with uniformly improved visualisation of penile shaft post-operatively. There were no significant post-operative complications apart from mild oedema which subsided over a period of 3 weeks. Genital hygiene had significantly improved in all the patients as a result of uninterrupted urinary stream.

Conclusion:
Retrograde progression of the inner preputial skin may be used as an effective technique to provide skin coverage to the penile shaft for reconstruction of congenital buried penis. It provides good functional and cosmetic results with adequate parental and patient satisfaction with minimal complications.
Phenotypic differences in clinical manifestations of generalized pustular psoriasis and severe plaque psoriasis in tropical Taiwan
Authors: Chao Yin-Cheng , Lee Chih-Hung 
Published: September 2024

Abstract

Background:
Generalized pustular psoriasis (GPP) is an uncommon variant of psoriasis. Clinical characteristics of GPP are limited due to its relatively low prevalence worldwide. Thus, the region-specific phenotypic differences between GPP and severe plaque psoriasis (SPP) remained not fully clarified.

Objectives:
This study aimed to compare the gender distribution, disease onset, clinical features, medical comorbidities, associated symptoms, laboratory findings, and potential precipitating factors of GPP and SPP in a single center in tropical Taiwan.

Methods:
A retrospective review was conducted for GPP and SPP in a tertiary medical center from 2003 to 2023. The GPP Area and Severity Index (GPPASI) and GPP Physician Global Assessment (GPPGA) score were used to measure the severity of GPP.

Results:
A total of 26 patients with GPP (mean age: 48.2 years) and 50 patients with SPP (defined as psoriasis area and severity index over 20 and undergoing biological agents more than 1 year, mean age: 41.3 years) were included in this study. Forty-six percentage of the GPP patients had a preceding history of psoriasis. While there was no gender or age predominance, patients with GPP tended to develop fever, hypertension, upper respiratory tract infection, leukocytosis, elevated C-reactive protein (CRP) levels, scalp involvement, be hospitalized and for a long time, along with allergy history of medications (diclofenac, ampicillin, and ceftriaxone), as compared to those with SPP. Hepatitis B virus and hepatitis C virus infections were less prevalent in GPP patients (with 15.4% and 3.8%, compared to 30.0% and 8.0% in SPP, respectively, although not statistically significant). The highest GPPASI and GPPGA scores occurred in young patients of GPP, but they are not associated with diseases of hypertension, hyperglycemia, or hyperlipidemia.

Conclusion:
Patients with GPP in Taiwan tended to have a higher hospitalization rate and longer mean hospitalization time along with increased occurrence of fever, leukocytosis, elevated CRP levels, and drug allergy. The younger patients of GPP tended to have higher GPPASI and GPPGA scores than the elder ones.
Exploring the Limits of Rescue Cerclage by Preoperative Sonography: Imaging Contribution and Therapeutic Considerations
Authors: Cheng I-Ning , Wu Meng-Hsing , Kang Lin 
Published: September 2024

Abstract
Cervical insufficiency poses risks for premature birth and neonatal outcomes. Preoperative sonography aids in the diagnosis and therapeutic considerations. Cervical cerclage is effective but carries risks. In our case series, 8 cases failed to complete emergent cerclage, leading to adverse outcomes. Analysis of preoperative images revealed thicker cervixes and cervical strictures may affect the surgical outcomes. Larger studies are needed to determine the reliable cutoff values. Preoperative assessment is crucial to inform treatment decisions.
Point-of-care Ultrasound: A Window into the Diagnosis of Atrial Myxoma in Stroke-like Patient
Authors: Chin Wei Ven , Khaw Mae Jane 
Published: September 2024

Abstract
Cardiac myxoma, the most common primary cardiac tumor, is indeed rare, with an estimated incidence of 0.03% in the general population. Despite its rarity, it can lead to severe complications such as intracardiac obstruction, emboli, and constitutional symptoms. Surgical excision of myxomas is associated with excellent outcomes and low rate of recurrence. Herein, we will report a case where the lesion was discovered early by point-of-care ultrasound (POCUS), allowing for the quickest possible prompt intervention. A 45-year-old man presented with a 1-day history of dizziness, right-sided body weakness, and facial asymmetry, which led to a motorbike fall. POCUS performed noted mass-like lesions measuring 7 cm by 6 cm, moving freely in the left atrium and prolapsing through the mitral valve during each cardiac cycle. The lesion appears to originate from the septal rather than the atrial appendage, which gives rise to a higher suspicion toward the left atrial myxoma than the left atrial thrombus. Besides, there are areas of liquefaction seen within the mass. He underwent a sternotomy and excision of the left atrial myxoma within the same hospitalization. Histopathology examination of the excised lesion confirmed the diagnosis of atrial myxoma. Early detection and surgical intervention result in a favorable prognosis. Upon discharge, he was stable, ambulating independently with minimal residual facial asymmetry.

Authors: Ahmed Marwa A.S. , Said Amr 
Published: September 2024

Background
Hormonal dysregulation impacts the metabolism of the cornea and could be linked to keratoconus. Previous research has suggested an association between keratoconus and autoimmune thyroid disorders.

Aim
The aim of this study was to compare the topographic corneal changes in patients with thyroid dysfunction.

Patients and methods
This is a cross-sectional study of 200 patients with thyroid dysfunction attending the Endocrinology Clinic at the Faculty of Medicine, Alexandria University. The corneal topography of patients was examined with TMS. Serum levels of thyroid-stimulating hormone, free thyroxine, and free triiodothyronine were measured.

Results
Two hundred patients with thyroid dysfunction were enrolled in the study. Of them, 129 were hypothyroid patients and 71 were hyperthyroid patients. The study included 137 females and 63 males with a mean age of 32.4 ± 8.2 years. Corneal keratometry readings, including K1, K2, and K max readings, were measured. The mean value of K1 was 45.86 ± 4.69 D, mean K2 was 47.89 ± 5.08 D and the mean corneal thickness was 475 ± 0.36 µm, no relation was found between any of these parameters and serum thyroid-stimulating hormone, free triiodothyronine, or free thyroxine levels.

Conclusion
In our study, more topographic changes in favor of a thin cornea and steep cornea rather than a true keratoconus were detected in patients with thyroid dysfunction, making cautious analysis of corneal topography important, especially before refractive surgery.

Published: September 2024

Highly efficient azo-day triazole derivatives carrying a π bond and OH electron donor groups have been designed, synthesized, and evaluated as colorimetric chemosensors for detecting metal ions in environmental samples, which was further supported by the functional theory studies and UV–Vis spectrophotometric experiment. The 4-amino-5-(2-((2,3-dimethylphenyl)amino)phenyl)-4H-1,2,4-triazole-3-thiol was directed to react with 3-nitrophenol during a diazotization type reaction to form an azo-day 4-((3-(2-((2,3-dimethylphenyl) amino)phenyl)-5-mercapto-4H-1,2,4-triazol-4-yl)diazenyl)-3-nitrophenol (Y), which have been confirmed by FTIR, 1H NMR, and could also be easily used for the detection metal ions. Compound (Y) exhibited a rapid quantitative method for the detection of Co(II) at λmax (532 nm) in an aqueous solution. The current study introduces a facile, low cost, more specific and selective chemosensor for detecting trace amounts of cobalt ions.

Considerable efforts have been directed towards addressing diabetes-induced infertility. In a twophase study designed to determine the effect of Spondias mombin (SM) aqueous leaf extract on blood glucose, spermiogram and gonadosomatic index of diabetes-induced wistar rats, forty male Wistar rats (170 - 250g) were randomly divided into ten groups (n=4) with five treated for 7 days for the first phase and five treated for 14 days in the second phase. Each phase had their five groups randomly assigned into control (non-diabetic), diabetic (untreated), diabetic concurrently treated with 5 mg/kg glibenclamide, 400mg/kg SM and 800 mg/kg SM. Diabetes mellitus was induced with intraperitoneal administration of alloxan hydrate at a dosage of 158mg/kg. Rats with fasting blood glucose of ≥ 190 mg/dL three days post alloxan administration was considered diabetic. Following this, the test substances were administered daily via oral gavage for 7 or 14 days. Blood glucose levels, spermiogram, body weight changes, gonadosomatic index (GSI), and testicular weights were evaluated at the end of each phase. Results revealed that SM caused a reduction in the blood glucose in a dose-dependent manner in alloxan-induced diabetic rats. In both phases, 800 mg/kg SM dosage improved the sperm motility and concentration. Also, at 400mg/ kg dosage, after 14 days of administration SM caused a progressive improvement in the sperm motility and concentration. The percentage of abnormal sperm cells varied between control and treatment groups but remained within the range of 18.50% to 57.00% after 14 days of treatment. The GSI was highest in 800 mg/kg SM group after 14 days when compared with other groups. This study concluded that the aqueous S. mombin leaf extract exhibited an ameliorative effect on diabetes-induced infertility when administered at dose of 800 mg/kg between 7 and 14 days.

Authors: Garba Sule Adamu 
Published: September 2024

An evaluation of sources information for raising village chickens was conducted among 72 farmers from nine communities in Bauchi State, Nigeria. Eight farmers were selected based on their experience and ownership of more than 20 chickens by members of the community during a group discussion session held with farmers, poultry traders and butchers and community leaders. The result showed respondents were mostly full-time farmers (65.3%) who were married (98.4%) and over 18 years of age with over 5 years of experience in village chicken farming (77.8%). A combination of Radio and community were identified by most respondents (32%) as their major source of information on village chicken production. Schools, on the contrary, were the least reported source of agricultural information (3%). Diversifying sources of information could likely enhance the effectiveness of reaching farmers with technical information on raising village chickens.
