Treatment of Hemorrhoids in Day Surgery: Stapled Hemorrhoidopexy vs Milligan–Morgan Hemorrhoidectomy

Background Recently, it has been demonstrated that surgical treatment of hemorrhoids in a day-care basis is possible and safe. The aim of this study was to compare the Longo stapled hemorrhoidopexy (SH) and the Milligan–Morgan hemorrhoidectomy (MMH). Methods One hundred seventy one patients (95 cases in SH group and 76 cases in MMH group) entered the study: 83 cases were III degree hemorrhoids, 88 IV degree. A priori and a post hoc power analysis were performed. Results, prospectively collected, were compared using chi squared test and student t test. Visual analog scale was used for pain evaluation. Postoperative pain, duration of pain, wound secretion, bleeding, resumption of a normal lifestyle, and postoperative complication were evaluated. Results Surgical time was 28.41 ± 10.78 for MMH and 28.30 ± 13.28 min in SH (P = 0.94). Postoperative pain was not different between MMH and SH during the first two postoperative days (4.73 ± 2.91 vs 5.1 ± 3.048; P = 0.4), during the following 6 days, patients treated with SH had less pain (4.63 ± 2.04 in MMH vs 3.60 ± 2.35 in SH; P = 0.006). In the SH group, seven patients needed further hospital stay for complicated course. SH showed higher incidence of anal fissure compared with MMH (6.3% vs 0%; P = 0.025) but no differences in urinary retention, anal stricture, urgency, or anal hemorrhage. Conclusions This study confirms that SH is associated with less postoperative pain and shorter postoperative symptoms, compared with MMH. SH may be a viable addition to the therapy for hemorrhoids with some advantages in early postoperative pain and some disadvantages in postoperative complications and costs.     

Case report: Leishmaniasis of the upper lip.

We report a case of leishmaniasis localized to the upper lip in a 77-year-old Italian man. The disease was characterized by a severe swelling which involved the right side of the upper lip. The swelling was slightly erythematous with crusts and scaling. Consistency was parenchymatous-hard. The lesion was asymptomatic. Histopathologic examination showed an inflammatory infiltrate consisting of lymphocytes, histiocytes, and plasma cells. Several Leishmania spp. amastigotes were observed in the cytoplasm of macrophages. Cultural examination on Novy-MacNeal-Nicolle medium was positive for Leishmania spp. Polymerase chain reaction was positive for Leishmania infantum. The patient was treated with i.m. N-methylglucamine antimonate, with complete remission in approximately 6 weeks. During follow-up of 9 months, no relapses were observed.     

Stronger association of drug-induced progressive multifocal leukoencephalopathy (PML) with biological immunomodulating agents

Aim  

The aim of the present study was to collect and compare cases of drug-induced PML in order to contribute to the debate about the role of the underlying diseases and/or drug immunosuppression in PML occurrence.     

Periodontal health in 200 HIV-positive patients

Two hundred HIV-positive subjects were surveyed to determine their periodontal health status. Particular attention was given to the occurrence of a severe and rapidly progressing form of periodontal disease designated "HIV-associated periodontitis", which has been reported as being unique to AIDS patients. Among the subjects comprising the cohort, 85 subjects had good gingival health, 59 subjects exhibited gingivitis, 49 cases of adult periodontitis were observed, 5 subjects presented with advance adult periodontitis, and 2 cases of necrotizing ulcerative periodontitis (NUP) were found within the group. The periodontitis of the patients in this survey did not have unique or pathognomonic characteristics which could set their periodontal disease apart from the periodontal disease seen in HIV negative population.     

Search for poliovirus long-term excretors among patients affected by agammaglobulinemia

Patients with agammaglobulinemia may excrete enteroviruses, including vaccine-derived poliovirus, for prolonged periods of time. This poses a risk to the patients but it also may pose a risk to the population after eradication of poliovirus and the cessation of routine vaccination. To assess this risk, a pilot study was performed to identify potential poliovirus long-term excretors in a cohort of 38 patients with a definite/presumptive diagnosis of X-linked agammaglobulinemia (XLA). Stool samples were analyzed to detect any polio or other enteroviruses replicating in the gut and neutralizing antibodies against polioviruses were measured in the sera. No viruses were isolated from the stool samples and most sera had neutralizing antibody levels against all three poliovirus serotypes considered by the WHO to be protective in immunocompetent individuals. This suggests that long-term excretion of enteroviruses in patients with agammaglobulinemia is relatively uncommon.     

Role of thalamic gamma-aminobutyrate in motor functions: catalepsy and ipsiversive turning after intrathalamic muscimol

Bilateral intrathalamic microinjections of nanogram amounts (5–50 ng) of muscimol, a γ-aminobutyrate (GABA) receptor agonist, elicited catalepsy in rats. Like neuroleptic-treated rats, those injected with muscimol in the thalamus remained suspended on a vertical grid but, unlike opioid-treated rats, they failed to remain horizontal on two book-holders. The righting reflex was present, while ptosis was absent. The areas with the highest sensitivity to the cataleptogenic effects of muscimol were the ventromedial and ventral-anterior nuclei of the thalamus. These thalamic areas were also characterized by the shortest latency for the induction of catalepsy. Injection of up to 50 ng of muscimol into the caudate, globus pallidus or entopeduncular nucleus failed to produce catalepsy. Catalepsy was also obtained after intrathalamic microinjection of other GABA analogs, such as 3-aminopropanesulphonic and imidazolacetic acid, which are known to be potent GABA receptor agonists, and β-p-chlorophenyl-GABA , a compound which has GABA mimetic activity. The catalepsy produced by 10 ng of muscimol was reversed by an intrathalamic microinjection of picrotoxin, a GABA receptor antagonist. Muscimol-induced catalepsy, unlike neuroleptic-induced catalepsy, was not reversed by systemic administration of high doses of apomorphine, a dopamine receptor agonist, or of scopolamine, a muscarine antagonist, or by intranigral injection of muscimol, and was not prevented by kainic acid-induced lesions of the striatum or of the nigra. Vice versa, injection of cataleptogenic doses of muscimol in the thalamus failed to prevent the stereotyped gnawing produced by systemic apomorphine or intranigral muscimol. Therefore, in these animals, catalepsy and stereotyped gnawing coexisted. The unilateral intrathalamic microinjection of muscimol resulted in a postural asymmetry consisting of turning towards the injected side. This ipsilateral posturing was converted into an ipsilateral circling by systemic administration of apomorphine.The results indicate that thalamic GABAergic mechanisms play an important role in the regulation of posture and in the mediation of certain motor responses arising in the striatum.     

Pain in individuals with RASopathies: Prevalence and clinical characterization in a sample of 80 affected patients

Pain in individuals with RASopathies is a neglected topic in literature. In this article, we assessed prevalence and profile of pain in a sample of 80 individuals affected by RASopathies. The study sample included individuals with Noonan syndrome (N = 42), Costello syndrome (N = 17), and cardio‐facio‐cutaneous syndrome (N = 21). A set of standardized questionnaires and scales were administered (VAS/numeric scale, r‐FLACC, Wang‐Baker scale, NPSI, BPI, NCCPC‐R) to detect and characterize acute and chronic pain and to study the influence of pain on quality of life (PEDs‐QL, SF‐36) and sleeping patterns (SDSC); revision of past medical history and multisystemic evaluation was provided. Available clinical data were correlated to the presence of pain. High prevalence of acute (44%) and chronic (61%) pain was documented in the examined sample. Due to age and intellectual disability, acute pain was localized in 18/35 individuals and chronic pain in 33/49. Muscle‐skeletal and abdominal pain was more frequently reported. The intensity of acute and chronic pain interfered with daily activities in 1/3 of the sample. Pain negatively impacted on QoL and sleeping patterns. This work documents that pain is highly prevalent in RASopathies. Future studies including subjective and objective measures of pain are required to discriminate a somatosensory abnormality from an abnormal elaboration of painful stimuli at a central level.     

Neurological phenotype of Potocki–Lupski syndrome

Potocki–Lupski syndrome is a condition mainly characterized by infantile hypotonia, developmental delay/intellectual disability (DD/ID), and congenital anomalies, caused by duplications of the 17p11.2 region, encompassing RAI1 gene. Its clinical presentation is extremely variable, especially for what concerns the cognitive level and the behavioral phenotype. Such aspects, as well as the dysmorphic/malformative ones, have been covered by previous studies; otherwise neurological features have never been systematically described. In order to delineate the neurological phenotype of Potocki–Lupski Syndrome, we collect an 8‐patients cohort. Developmental milestones are delayed and a mild to moderate cognitive impairment is present in all patients, variably associated with features of autism spectrum disorder, behavioral disturb, and sleep disturb. Hypotonia appears a less frequent finding than what previously reported, while motor clumsiness/coordination impairment is frequent. EGG registration demonstrated a common pattern with excess of diffuse rhythmic activity in sleep phases or while the patient is falling asleep. Brain MRI did not reveal common anomalies, although unspecific white matter changes may be present. We discuss such findings and compare them to literature data, offering an overview on the neurological and cognitive‐behavioral presentation of the syndrome.
