A case of colouterine fistula managed laparoscopically

Fistulas between the uterus and bowel are rarely reported. We report successful laparoscopic management of a colouterine fistula caused by a foreign body in the uterus. Fistulas between the gastrointestinal tract and the female genital tract are usually found between the vagina and rectum as a result of complications of childbirth or iatrogenic trauma. Communication between the uterus and bowel is rarely reported. We report successful laparoscopic management of an unusual case of colouterine fistula caused by a foreign body in the uterus.     

Complete and incomplete lower motor neuron facial palsy in post-COVID-19 mucormycosis

Purpose:To study facial nerve palsy (FNP) in post-COVID-19-mucormycosis patients and its ocular complications, report different presentations of FNP in such patients, and propose its etiopathogenesis based on presentation and clinico-radiologic localization.Methods:A prospective cohort study was carried out in patients of post-COVID-19-mucormycosis who presented at our tertiary center, over a period of 3 months. Motor and sensory examination of the facial nerve was done to diagnose FNP and localize the lesion clinically. Slit-lamp examination was done for grading corneal involvement. MRI brain, orbit, and paranasal sinuses (PNS) with contrast were studied to find involvement along the facial nerve. It was assessed whether this site of lesion corresponded with clinical localization. Data were analyzed using the percentage of total cases and Fisher’s test.Results:A total of 300 patients with post-COVID-19 mucormycosis were examined, of which 30 (10%) patients were found to have FNP. All were lower motor neuron (LMN) type and were associated with corneal complications. The most common site clinically was distal to the chorda tympani (66.66%) and radiologically was infratemporal (IT) fossa (63.4%). The clinical localization significantly correlated with the radiological findings (P = 0.012). Twenty percent of patients showed incomplete involvement of facial musclesConclusion:FNP was found to be of LMN type. The most common site of insult was IT fossa. There was a good clinico-radiological correspondence of lesions. Isolated lesions were also found along the peripheral nerve course, presenting as incomplete facial palsy. Recognition of FNP in post-COVID-19 mucormycosis, in all its variable forms, is important to manage corneal complications.     

Prediction of antimalarial activity of some cyclic peroxy ketals using physico-chemical and topological indices

This study is based on modeling the anti-malarial activity (log IC₅₀/nm) of 20 cyclic peroxy ketals using topological and physicochemical parameters. The multiple regression analysis reveals that the five-parametric model containing MW, ST, χ _eq, ⁰ χ ^v, IP₂ as correlating parameters is the best for modeling the activity of the compounds under present study. The cross-validated parameters have been calculated by LOO cross-validation procedure for validation of proposed model.     

Pellagra in a child–A rare entity

This case has been presented as pellagra, which is very rare in children. Pellagra is due dietary deficiency of niacin. Usually seen in alcoholics, malabsorption syndromes occur very rarely in children. A 11-y-old girl presented with well-defined, hyperpigmented, hyperkeratotic, symmetrical, thick scaly plaques surrounded by erythema on the dorsum of the hands, arms, feet, legs up to knees, and along the sides of the neck. The child was given 100 mg of Nicotinamide. Skin lesions resolved rapidly with the treatment and the child improved.     

Pseudo-aneurysm of mitral aortic intervalvular fibrosa: Two case reports

The fibrous body between the mitral and aortic valve, known as mitral-aortic intervalvular fibrosa (MAIVF) is prone to infection and injury resulting in pseudo-aneurysm formation. Because of its relative rarity, we are far from making any conclusion regarding the natural history and appropriate therapeutic strategy for this condition. We report two cases of this condition with two different and rare etiologies with strikingly different natural courses, providing insight into the natural course and timing of surgery in this rare entity.
