AimTransanal haemorrhoidal dearterialization (THD) has become well established for the treatment of haemorrhoids. In this study we describe a technical modification of this technique, targeted mucopexy (THD TM), and report the results for advanced haemorrhoids.MethodThe study included a prospective evaluation of patients with Grade IV (fourth-degree) haemorrhoids operated on with the THD TM technique. This consisted of an initial dearterialization when the haemorrhoidal arteries were transfixed and a second phase of mucopexy, using a different needle from that usually used in the original technique.ResultsFrom January 2007 to December 2011, 31 consecutive patients with Grade IV haemorrhoids were operated on using the THD TM technique. Postoperative pain was reported by 22 (70%) patients on day 1 and 19 (61%) on day 7, while nine (30%) did not experience any pain at all. Severe pain was reported by only nine (16%) patients. At a mean follow-up of 32 months, two (6.4%) patients required a further intervention for on-going symptoms.ConclusionTransanal haemorrhoidal dearterialization TM is effective for advanced haemorrhoids.What does this paper add to the literatureThis paper describes a technical modification of the original transanal haemorrhoidal dearterialization technique introduced by the senior author and reports the results achieved with it in patients with Grade IV haemorrhoids. We believe the modification has allowed a significant improvement in the outcome, especially when dealing with advanced haemorrhoids.

This study was conducted to determine the prevalence of hypomagnesemia and its effect on the lipid profile of local type II diabetic patients. For this purpose, 219 diabetic patients and 100 age-matched control subjects were enrolled. Blood samples of the subjects were analyzed for fasting glucose, Mg, triglyceride, total cholesterol, HDL-cholesterol, and LDL-cholesterol. Results showed that mean serum values of these parameters were differing in diabetic patients as compared to control subjects. The reference range of serum magnesium in healthy controls was 1.2-4.4 mg/dl. Mean serum magnesium in diabetic patients was significantly lower as compared to healthy subjects (1.6 ± 0.23 mg/dl vs. 2.8 ± 0.8 mg/dl). Among diabetic patients, 143 (65.3%) had serum magnesium level below 1.7 mg/dl (hypomagnesemia). The corresponding figure for control subjects was 11 (11%). The difference was significant (p < 0.01). Diabetes mellitus patients with current hyperglycemic status had significantly lower serum Mg as compared to euglycemic patients (p = 0.05). Serum Mg in diabetic patients was correlated with all lipid parameters. Among them, HDL-cholesterol was significantly (p < 0.05) positively correlated (r = 0.34), while total cholesterol and LDL-cholesterol was negatively correlated, albeit non-significantly, with serum Mg. These results demonstrate that hypomagnesemia is accompanied by atherogenic alterations in the lipid profiles of type II diabetic patients of Lahore, Pakistan.

Problem Statement. Thyroid gland in women undergoes functional changes during pregnancy. A few studies have described such changes in pregnant women residing in iodine deficient areas. Objective. To document these changes in pregnant women residing in Lahore, a low iodine intake urban area of Pakistan. Patients and Methods. In 254 pregnant women, data of FT4, FT3, and TSH during the first and subsequent trimesters were obtained and compared with those of 110 nonpregnant women. These hormones were determined in serum by radioimmunoassay (RIA) techniques using commercial kits. Results. Compared to nonpregnant women mean FT4 level was decreased, and FT3 and TSH increased significantly (P < 0.05) in pregnant women. A negative correlation of FT4 with TSH was observed in all three trimesters. Serum FT3 was positively correlated with TSH only during the third trimester. As a function of gestation time, FT4 levels progressively decreased, and FT3 and TSH levels increased significantly (one-way ANOVA F = 108.2, 17.3, and 44.8, resp.; all P < 0.05) exhibiting thyroid gland adaptations. Conclusion. Pregnancy is associated with significant alterations in thyroid function due to low iodine intake in women residing in study area. The compensated thyroid function poses a risk of thyroid failure in a number of pregnant women.

Background Primary vesicoureteral reflux (PVUR) is the most common malformation of the kidney and urinary tract and reflux nephropathy is a major cause of chronic kidney disease in children. Recently, we reported mutations in tenascin XB (TNXB) as a cause of PVUR with joint hypermobility. Methods To define the role of rare variants in tenascin genes in the etiology of PVUR, we screened a cohort of patients with familial PVUR (FPVUR) and non-familial PVUR (NFPVUR) for rare missense variants in TNXB and tenascin C (TNC) genes after excluding mutations in ROBO2 and SOX17. Results We identified 134 individuals from 112 families with PVUR, we excluded two families with mutations in ROBO2. We found rare missense variants in TNXB in the remaining 110 families comprising of 5/55 (9%) of families with FPVUR and 2/55 (4%) of NFPVUR. There were no differences in high-grade reflux, or renal parenchymal scarring between patients with and without TNXB variants. All patients with TNXB rare variants that were tested exhibited joint hypermobility. Overall we were able to identify causes of FPVUR in 7/57 (12%) families (9% in TNXB and 3% in ROBO2). Conclusions In conclusion, a rare missense variant in TNXB in combination with a positive family history of VUR and joint hypermobility may represent a non-invasive method to diagnose PVUR and warrants further evaluation in other cohorts.

Purpose To assess visual acuity, binocular defocus curve, spectacle independence, and photic phenomena after bilateral same-day cataract surgery with implantation of an extended depth-of-focus intraocular lens (IOL) with mini-monovision. Methods Single-center retrospective study including 124 eyes from 62 patients who underwent bilateral implantation of an isofocal EDOF lens [Isopure® (BVI)] with mini-monovision (−0.50 D). Refraction, visual acuity at different distances, binocular defocus curves, spectacle independence, and subjective ratings of picture-referenced photic phenomena were assessed one to two months postoperatively. Results The mean postoperative refractive spherical equivalent was −0.15±0.41D in the dominant eyes and −0.46±0.35D in the mini-monovision eyes (p<0.01). Overall, 98.4% and 87.7% of the eyes were within ±1.00D and ±0.50D of the target refraction, respectively. Postoperative monocular corrected distance visual acuity was −0.04±0.07 logMAR. Binocular uncorrected visual acuity was −0.02±0.07, 0.13±0.11and 0.40±0.20 logMAR for far, intermediate and near, respectively. At the visual acuity threshold of 0.20 logMAR (or better) the defocus curve ranged from −1.6D to +0.9D. Reported spectacle-independence was 96% for far distance, 95% for intermediate, and 34% for near. Five percent of patients reported halos, 16% starburst, and 16% glare. Only 7% of all patients considered them bothersome. Conclusion In patients undergoing same-day bilateral cataract surgery, an isofocal EDOF lens provided an extended range of functional vision, up to 63 cm, resulting in useful uncorrected near vision, good uncorrected intermediate vision, and excellent uncorrected distance vision. Subjective patient satisfaction in terms of spectacle independence and photic phenomena was high.
