Surveillance for lumpy skin disease and foot and mouth disease in the Kimberley, Western Australia.

We quantified the sensitivity of surveillance for lumpy skin disease (LSD) and foot and mouth disease (FMD) in cattle in the Kimberley region of Western Australia. We monitored producer and veterinary activity with cattle for 3 years commencing January 2020. Each year, ~274,000 cattle of 685,540 present on 92 pastoral leases (stations) were consigned to other stations, live export or slaughter. Veterinarians examined 103,000 cattle on the stations, 177,000 prior to live export, and 10,000 prior to slaughter. Detection probabilities for the disease prior to transport or during veterinary procedures and inspections were elicited by survey of 17 veterinarians working in Northern Australia. The veterinarians estimated the probabilities that they would notice, recognise, and submit samples from clinical cases of LSD and FMD, given a 5% prevalence of clinical signs in the herd. We used scenario tree methodology to estimate monthly surveillance sensitivity of observations made by producers and by veterinarians during herd management visits, pre-export inspections, and ante-mortem inspections. Average monthly combined sensitivities were 0.49 for FMD and 0.37 for LSD. Sensitivity was high for both diseases during the dry season and low in the wet season. We estimated the confidence in freedom from the estimated surveillance sensitivity given one hypothetically infected herd, estimated probability of introduction, and prior confidence in freedom. This study provided assurance that the Kimberley is free of these diseases and that routine producer and veterinary interactions with cattle are adequate for the timely detection of the disease should they be introduced.

Comparative effectiveness of surgeon-performed transversus abdominis plane blocks and epidural catheters following open hernia repair with transversus abdominis release.

PURPOSE: Recovery protocols aim to limit narcotic administration following ventral hernia repair (VHR). However, little is known about the contribution of a protocol's individual components on patient outcomes. We previously reported that surgeon-performed transversus abdominis plane block (TAP-block) is more effective than ultrasound-guided TAP-block following VHR. This study evaluates the effectiveness of two postoperative analgesia modalities: epidural catheter and surgeon-performed TAP-block following VHR performed with transversus abdominis release (TAR). METHODS: A retrospective analysis was performed on data prospectively collected between 2012 and 2019. All patients undergoing open VHR with TAR performed by a single surgeon were identified. Parastomal hernia repairs and any patients receiving ultrasound-guided TAP blocks or paraspinal blocks were excluded. Primary outcome was length of stay (LOS) with secondary outcomes including pain scores, opioid requirements, and 30-day morbidity. Linear regression was used to model LOS. RESULTS: One hundred thirty-five patients met inclusion criteria (63 epidural, 72 TAP-block). The majority (67.4%) of patients were modified ventral hernia working group grade 2. The only statistically significant difference in postoperative pain scores between the groups was on postoperative day 2 (TAP block 3.19 versus epidural 4.11, p = 0.0126). LOS was significantly shorter in the TAP block group (4.7 versus 6.2 days, p = 0.0023) as was time to regular diet (3.2 versus 4.7 days, p < 0.0001). After controlling for confounders, epidural was associated with increased LOS by 1.3 days (p = 0.0004). CONCLUSION: Epidural use following VHR with TAR is associated with increased LOS and increased time to regular diet without reducing pain or opioid use when compared to surgeon-performed TAP block.

Changes in the lateral abdominal wall following endoscopic subcutaneous anterior component separation.

PURPOSE: Although changes in lateral abdominal wall musculature after posterior component separation with transversus abdominis release have been investigated, the effects of endoscopic subcutaneous anterior component separation (ES-ACS) on postoperative muscle anatomy have not been evaluated. The purpose of this study was to evaluate changes in the lateral abdominal muscles after ES-ACS. METHODS: Computed tomography (CT) images of patients who underwent ES-ACS were retrospectively evaluated. Lateral abdominal wall thickness and external oblique displacement were measured at the level of fixed retroperitoneal structures. Measurements on the ES-ACS side were compared with those on the contralateral undivided side or with preoperative images in patients with bilateral procedures. RESULTS: Fifteen patients met the criteria for study inclusion. Most patients (n = 13, 86.7%) underwent unilateral ES-ACS. The most commonly performed procedure was laparoscopic intraperitoneal onlay mesh-plus hernia repair (n = 12, 80.0%; the remaining patients underwent open repair). The Mean defect width was 8.4 cm (range 6-15 cm). There was no difference in the thickness of the lateral abdominal musculature between ES-ACS and undivided sides. There was a significant lateral displacement of the external oblique muscle from the lateral edge of the rectus abdominis on the ES-ACS side (mean distance 3.7 cm; p = 0.0006). No midline hernia recurrences, iatrogenic linea semilunaris hernias, or lateral eventrations were observed during a mean follow-up period of 2.6 years (range 0.5-7.4 years). CONCLUSION: ES-ACS resulted in no atrophy of the lateral abdominal muscles in long-term CT follow-up. The procedure is a safe and effective adjunct to complex hernia repair in selected patients.

Resolution of Chronic Shoulder Pain after Repair of a Posttraumatic Diaphragmatic Hernia: A 22-Year Delay in Diagnosis and Treatment.

Diagnosing traumatic diaphragmatic rupture (TDR) due to penetrating rib fractures is challenging because the lesions are often too small to be detected and may present years after injury. Patients with delays in diagnosis of TDR rarely present with orthopaedic-related complaints of pain. We report the case of a 52-year-old female who presented with chronic left shoulder pain following a motor vehicle accident (MVA). In addition to left-side lower rib fractures, she also sustained a left-sided splenic laceration, pneumothorax, and two-part upper humerus fracture. Fracture treatment was percutaneous pinning; the other injuries were treated nonoperatively. Her shoulder pain could not be attributed to shoulder or neck pathology. Twenty years after the MVA, she began experiencing episodes of left-sided abdominal pain and nausea. A CT scan obtained two years later revealed a diaphragm hernia, which was repaired laparoscopically. Unique aspects of this case include (1) presentation to an orthopaedic surgeon with a chief complaint of chronic shoulder pain; (2) at 22 years, this is the fourth longest case of a delay in diagnosis of TDR; and (3) the unique symptom of ipsilateral referred shoulder pain, which immediately improved after hernia repair.

RISK FACTORS FOR READMISSION AND LENGTH OF INPATIENT STAY IN RURAL GHANA FOLLOWING EXPLORATORY LAPAROTOMY.

BACKGROUND: Increased inpatient length of stay (LOS) and readmission represent significant economic burden on patients and families faced with surgical disease in low-middle income countries given limited surgical access, infrastructure, and variable insurance status. STUDY AIM: Identify risk factors for readmission and inpatient LOS in postoperative care in the Eastern Regional Hospital, Ghana. STUDY DESIGN: Retrospective case series. SETTING: Eastern Regional Hospital, Koforidua, Ghana. METHODS: Data for exploratory laparotomy procedures were obtained from surgical case logs collected at the regional referral hospital in Koforidua, Eastern Region, Ghana from July 2017 to June 2018. This information was combined with the hospital electronic medical records to collect demographic data, laboratory values, and outcomes. Multivariable analyses were used to model LOS and readmission. RESULTS: The study included 346 exploratory laparotomy procedures (286 adult, 60 pediatric) for various surgical diseases. The overall 30-day readmission rate was 9.2%. Average LOS was 12.0±20.4 days for readmitted patients and 6.7±5.5 days for patients without readmission. Readmitted patients were more likely to have had preoperative anemia (p=0.009), surgical site infection (P=0.001), or a re-laparotomy (p=0.005). Preoperative anemia (OR=3.5 [95% CI 1.54-7.96], p=0.003) and surgical site infection (OR=3.68 [95% CI 1.36-10.00], p=0.011) were associated with increased odds of readmission. Preoperative anemia was also associated with about 3.0 additional inpatient days (p=0.001). CONCLUSION: Preoperative anemia and surgical site infections represent risk factors for readmission in rural Ghana. Anemia is also associated with longer LOS. Future interventions aimed at treating anemia and preventing surgical site infections may reduce some of the post-operative burden placed on patients and their families.

Acrodermatitis dysmetabolica in an infant with maple syrup urine disease.

Acrodermatitis dysmetabolica (AD) is a rare, newly termed, and poorly understood disease that appears to be clinically similar to acrodermatitis enteropathica (AE). Both diseases are characterized by the triad of periorificial and acral dermatitis, diarrhoea, and alopecia. Unlike AE, which is caused by zinc deficiency, AD is caused by numerous metabolic disorders. One such disorder is maple syrup urine disease (MSUD), a genetic deficiency of branched chain α-ketoacid dehydrogenase, the enzyme that degrades the branched-chain amino acids (BCAAs) isoleucine, leucine and valine. Treatment involves restricting BCAAs to prevent accumulation. We report a case of an infant being treated for MSUD, who developed the triad of AE/AD after a period of poor BCAA formula intake. The child was found to have low isoleucine and normal zinc levels. Increasing the isoleucine dose improved the eruption, thus the diagnosis of AD secondary to isoleucine deficiency was made. This case emphasizes the importance of carefully balancing BCAA levels while treating MSUD, as deficiency can precipitate AD.

Lack of impact of semen quality on fertilization in assisted conception.

BACKGROUND: Defective semen quality is one of the commonest causes of infertility. The diagnosis of male fertility depends upon a descriptive evaluation of human semen, however a normal semen analysis does not necessarily indicate satisfactory fertility potential. AIMS: (i) to examine the semen quality of patients undergoing treatment by assisted conception, (ii) to explore relationships between semen quality and treatment outcomes, and (iii) to look at inter-laboratory variation in the assessment of semen quality. METHODS: Semen quality in patients undergoing assisted conception treatment between 2001 and 2004 was reviewed. Data on female age, egg numbers and fertilization outcomes was obtained by case note review. RESULTS: The thresholds used to direct patients towards IVF or ICSI treatment were comparable with the normal values promulgated by WHO, with the exception of morphology. Semen quality was not predictive of fertilization rates. When the results of independent measurements of the same sample were compared, there was diagnostic disagreement in between 10%-29% of samples. CONCLUSIONS: The conventional criteria of semen quality are used to determine treatment strategy for couples undergoing assisted conception but are not reflected in fertilization rates, emphasising the limited utility of the conventional criteria of semen quality in the assessment of sperm function. There remains significant inter-laboratory variation in the results of semen analysis.

Perinatal management of harlequin ichthyosis: a case report and literature review.

Harlequin ichthyosis (HI) is a rare and severe form of congenital ichthyosis. Linked to deletion and truncation mutations of a keratinocyte lipid transporter, HI is characterized by diffuse epidermal hyperkeratinization and defective desquamation. At birth, the HI phenotype is striking with thick hyperkeratotic plate-like scales with deep dermal fissures, severe ectropion and eclabium, among other findings. Over the first months of life, the hyperkeratotic covering is shed, revealing a diffusely erythematous, scaly epidermis, which persists for the remainder of the patient's life. Although HI infants have historically succumbed in the perinatal period related to their profound epidermal compromise, the prognosis of HI infants has vastly improved over the past 20 years. Here, we report a case of HI treated with acitretin, focusing on the multi-faceted management of the disease in the inpatient setting. A review of the literature of the management of HI during the perinatal period is also presented.

A case of extensive Aplasia Cutis Congenita with underlying skull defect and central nervous system malformation: discussion of large skin defects, complications, treatment and outcome.

Aplasia Cutis Congenita (ACC) is a rare condition characterized by the absence of a portion of skin at birth. Skin defects are usually small (0.5 to 3 cm) and located on the scalp. Although there can be other physical or genetic abnormalities, ACC is most often a benign isolated condition. Rarely is an underlying bony defect present, and this association increases the rate of complications. We report a case of a newborn male with ACC of the entire crown and vertex scalp, non-ossified parietal skull and dysplastic corpus callosum. The patient's skull and skin defects were treated non-surgically, and he recovered well.

Subcutaneous fat necrosis in a newborn following icebag application for treatment of supraventricular tachycardia.

Cases of subcutaneous fat necrosis of the newborn (SCFN) and neonatal cold panniculitis have been reported most often secondary to perinatal distress or hypothermia. We present a case of a newborn infant who developed erythematous, indurated plaques on both cheeks and right shoulder following ice pack application for supraventricular tachycardia. The distinction between SCFN and cold panniculitis is important as SCFN may have complications such as hypercalcemia, whereas cold panniculitis is not associated with such sequelae. Clinicians should be aware of the diagnostic similarities and differences between these two conditions because of differences in potential serious sequelae.

Eccrine angiomatous hamartoma: a report of symmetric and painful lesions of the wrists.

Eccrine angiomatous hamartoma (EAH) is a rare, benign cutaneous lesion histologically defined as a proliferation of eccrine glands within a closely associated vascular stroma. Typically EAH presents as a solitary flesh-colored, hyperhidrotic, painful papule or plaque appearing at birth or during childhood. Only two previously reported cases have been described involving multiple, symmetrically located lesions. The occurrence of knuckle pads in patients with EAH has not been reported. We present an instance of multiple painful EAH lesions occurring symmetrically on the extensor wrists in a 14-year-old girl with knuckle pads.

Elevated leptin levels are associated with excess gains in fat mass in girls, but not boys, with type 1 diabetes: longitudinal study during adolescence.

Adolescents, in particular girls, with type 1 diabetes may gain excessive weight during puberty. We present the results of a longitudinal study aimed to determine the roles of leptin and insulin in changes in body composition in subjects with type 1 diabetes and controls. Forty-six children (23 boys) with type 1 diabetes and 40 controls (20 boys) were followed from 8-17 yr of age. Height, weight, and sc skinfolds were assessed every 6 months, and a blood sample taken for leptin determination. Throughout the age range, body mass index (mean +/- SEM) was greater by 1.45 +/- 0.69 kg/m(2) in girls and 1.46 +/- 0.55 kg/m(2) in boys with type 1 diabetes compared with control values. In girls with type 1 diabetes, this reflected greater percent body fat (3.2 +/- 1.0%; P = 0.002), whereas in boys it related to differences in fat-free mass. Both boys and girls with type 1 diabetes had higher leptin levels adjusted for percent body fat than controls; in the girls this was related to insulin dose (regression coefficient B = 0.006 +/- 0.003; P = 0.04) and greater gains in fat mass. Hyperinsulinemia and raised leptin levels are associated with gains in fat mass throughout puberty in girls, but not boys, with type 1 diabetes.

Pediatric exanthems.

Many childhood diseases have cutaneous manifestations such as exanthems. More than 50 agents (viral, bacterial, or rickettsial) that cause exanthems in children have been identified. This article describes a systematic approach for evaluating 12 common exanthems. Diagnosis is made by correlating the location, morphology, and timing of the eruption with associated constitutional signs and symptoms.

Characteristics and quality of Papanicolaou smears obtained by primary care clinicians using a single commercial laboratory.

BACKGROUND: Few data are available on factors associated with the quality of Papanicolaou smears performed in primary care. OBJECTIVE: To identify the patterns and proficiency of cervical cancer screening among different primary care specialties. MATERIALS AND METHODS: Clinical and cytologic data from 21,833 Papanicolaou smears, submitted to a single large commercial laboratory by 176 clinicians during a 7-month period, were correlated with individual clinician and specialty characteristics according to indexes of specimen quality. RESULTS: Obstetrician-gynecologists, nurse practitioners, and physician assistants provided screening to a younger population of women compared with family physicians, internists, and general practitioners. Factors positively associated with a greater probability of a "satisfactory" smear or the presence of endocervical cells (as a marker of adequate sampling) were increasing patient age, use of the cytobrush, and the specialty of the obstetrician-gynecologist. Satisfactory smears were not associated with any increased identification of cytologic abnormalities compared with "limited" smears. In contrast, smears with endocervical cells showed a higher proportion of abnormalities compared with specimens without such cells. CONCLUSIONS: Differences in the performance of obtaining Papanicolaou smears exist between primary care specialties, but need further clarification. The use of the cytobrush and the presence of endocervical cells are criteria that reflect clinician proficiency more realistically than the laboratory criterion of satisfactory smear.

The effect of the quality of Papanicolaou smears on the detection of cytologic abnormalities.

BACKGROUND: Controversy continues regarding the relation between the quality of Papanicolaou (Pap) smears, especially the presence of endocervical cells (ECC), with the finding of cytologic abnormalities. METHODS: As part of a study regarding performance feedback on the quality of Pap smears, data from 56,475 Pap smears obtained by 176 participating clinicians over a 20-month period were analyzed to assess the relation between the presence of ECC, the categorization of global specimen adequacy as "satisfactory" or "satisfactory with limitations," and the prevalence of atypia and squamous intraepithelial lesions (SILs). RESULTS: Atypia was less likely to be found in "satisfactory" Pap smears than in "satisfactory with limitations" quality Pap smears (odds ratio [OR], 0.6; 95% confidence interval [CI], 0.5-0.6; P < 0.001), even though the latter could contain ECC. No association was found between satisfactory Pap smears and cytologic abnormalities. Compared with specimens with no ECC, an ECC count of > or = 50 on a slide was associated positively with the detection of atypia (OR, 2.1; 95% CI, 1.8-2.4; P < 0.001) or SILs (OR, 1.7; 95% CI, 1.3-2.2; P < 0.001). A similar relation existed between ECC counts of 25-50 (OR, 1.9; 95% CI, 1.1-2.2; P = 0.01) and the detection of SILs. No relation was found between specimens with < 25 ECC and the presence of atypia or abnormalities. CONCLUSIONS: The global adequacy criterion of "satisfactory" assigned to a Pap smear does not indicate that there is a greater likelihood of detecting cytologic abnormalities compared with lower quality Pap smears. To the authors' knowledge, previous studies regarding the link between ECC in the Pap smear and cytologic abnormalities have not addressed the relevance of how many ECC are needed to maximize the identification of abnormalities. The data from the current study support the value of obtaining at least 25 ECC as a quality indicator of sampling.

Longitudinal study of leptin concentrations during puberty: sex differences and relationship to changes in body composition.

Leptin may have a role in the initiation of puberty and the regulation of subsequent weight gain, but this hypothesis has not been tested by longitudinal study. We report data from 40 normal children (20 boys and 20 girls) followed from 8-16 yr of age with hormone measurements and auxology every 6 months. Before the onset of puberty, leptin levels were similar in boys and girls: G1, mean (95% confidence interval), 2.63 (2.17-3.20) ng/mL; B1, 2.47 (2.08-2.94) ng/mL (P = 0.64) and increased with age in both sexes (B, 0.107 +/- 0.042; P = 0.02). With the onset of puberty, leptin levels increased in girls (B2-B5, P < 0.0005), but decreased in boys (G2-G5, P < 0.0005). Similar positive independent relationships were seen between leptin and fat mass in girls (B, 0.106 +/- 0.022; P < 0.0005) and boys (B, 0.121 +/- 0.020; P < 0.0005), and negative relationships were found with fat-free mass [girls: B, -1.104 +/- 0.381 (P < 0.005); boys: B, -1.288 +/- 0.217 (P < 0.0005)]. Girls gained more fat mass than boys, whereas boys gained more fat-free mass, and this explained the sex difference in leptin levels. Leptin levels correlated significantly with a large number of other hormones, but none was independent of changes in body composition. In girls, but not in boys, low leptin levels during prepuberty (B1) predicted subsequent gains in the percent body fat during puberty (r = -0.75; P = 0.005). The sexual dimorphism in leptin levels during puberty reflects differential changes in body composition. Prepubertal leptin levels in girls also predict gains in the percent body fat.
