The species of Billaea Robineau-Desvoidy (Diptera, Tachinidae) from the eastern Palearctic and Oriental regions are revised. Ten described species are recognized, viz. B. atkinsoni (Baranov) (new records for Japan, Laos, Malaysia, Pakistan and Thailand), B. ficorum (Townsend), B. fortis (Rondani), B. impigra Kolomiets (new record for China), B. kolomyetzi Mesnil, B. malayana Malloch, B. morosa Mesnil, B. robusta Malloch, B. steini (Brauer et Bergenstamm) and B. triangulifera (Zetterstedt) and nine species are described as new to science, B. brevicauda Zhang et Shima sp. nov. (China), B. carinata Zhang et Shima sp. nov. (China), B. chinensis Zhang et Shima sp. nov. (China and Vietnam), B. flava Zhang et Wang sp. nov. (China), B. kurahashii Zhang et Shima sp. nov. (Laos and Thailand), B. micronychia Zhang et Shima sp. nov. (China and Japan; previously misidentified from China as B. irrorata (Meigen)), B. papei Zhang et Shima sp. nov. (Malaysia), B. setigera Zhang et Shima sp. nov. (China) and B. verticalis Shima et Zhang sp. nov. (China). Billaea fasciata (Townsend, 1928) is treated as a junior synonym of B. ficorum (Townsend, 1916), syn. nov. Billaea irrorata is no longer recorded from the eastern Palearctic. A key to 19 species of Billaea from the eastern Palearctic and Oriental regions and 101 figures of male terminalia, bodies, heads and abdomens are given.

Chan EWM, Hamid MSA, Nadzalan AM, Hafiz E

Hong Kong physiotherapy journal : official publication of the Hong Kong Physiotherapy Association Limited = Wu li chih liao, 2020 Dec;40(2):89-97.

PMID: 33005073 DOI: 10.1142/S1013702520500080

Background: Sahrmann five-level core stability test protocol has been used to evaluate the ability of the core muscles to stabilize the spine. However, validation studies on the Sahrmann protocol are limited.

Objective: The purpose of this study was to compare the different levels of Sahrmann five-level core stability (levels 1-5) on the muscle activity of rectus abdominis (RA), external oblique (EO), and transverse abdominis/internal oblique (TrA/IO).

Methods: Twenty-two asymptomatic male participants aged 21.3
6
±

.59 years were recruited. Participants were instructed to perform maximum voluntary contraction (MVC) and five levels of Sahrmann five-level core stability test guided with a pressure biofeedback unit (PBU). The surface electromyography (EMG) data of each muscle during five levels of Sahrmann five-level core stability test were normalized as a percentage of MVC.

Results: Results showed significant differences in the normalized EMGs of RA [

Penetrating injury to the abdominal viscera is not uncommon unless when it is caused by marine life. We present a 39-year-old fisherman from a tropical country who had sustained a penetrating injury from a stab wound to the abdomen due to needlefish impalement. He sustained a small perforation of the sigmoid colon during exploratory laparotomy and primary repair was done. Although this incident is rare, there are cases involving seawater activities either for leisure, sport or diving for fishing. We highlight this rare incident and discuss the management plan.

Radiation dose reduction in thoracic and abdomen-pelvic CT using tube current modulation: a phantom study

Sabarudin A, Mustafa Z, Nassir KM, Hamid HA, Sun Z

J Appl Clin Med Phys, 2015 Jan;16(1):319-328.

PMID: 28297258 DOI: 10.1120/jacmp.v16i1.5135

This phantom study was designed to compare the radiation dose in thoracic and abdomen-pelvic CT scans with and without use of tube current modulation (TCM). Effective dose (ED) and size-specific dose estimation (SSDE) were calculated with the absorbed doses measured at selective radiosensitive organs using a thermoluminescence dosimeter-100 (TLD-100). When compared to protocols without TCM, the ED and SSDE were reduced significantly with use of TCM for both the thoracic and abdomen-pelvic CT. With use of TCM, the ED was 6.50±0.29 mSv for thoracic and 6.01±0.20 mSv for the abdomen-pelvic CT protocols. However without use of TCM, the ED was 20.07±0.24 mSv and 17.30±0.41 mSv for the thoracic and abdomen-pelvic CT protocols, respectively. The corresponding SSDE was 10.18±0.48 mGy and 11.96±0.27 mGy for the thoracic and abdomen-pelvic CT protocols with TCM, and 31.56±0.43 mGy and 33.23±0.05 mGy for thoracic and abdomen-pelvic CT protocols without TCM, respectively. The highest absorbed dose was measured at the breast with 8.58±0.12 mGy in the TCM protocols and 51.52±14.72 mGy in the protocols without TCM during thoracic CT. In the abdomen-pelvic CT, the absorbed dose was highest at the skin with 9.30±1.28 mGy and 29.99±2.23 mGy in protocols with and without use of TCM, respectively. In conclusion, the TCM technique results in significant dose reduction; thus it is to be highly recommended in routine thoracic and abdomen-pelvic CT. PACS numbers: 87.57.Q-, 87.57.qp, 87.53.Bn.

Komatsu N, Lio H, Ooi HK

Trop Biomed, 2021 Jun 01;38(2):48-52.

PMID: 33973572 DOI: 10.47665/tb.38.2.036

We described a new species of cockroach, Periplaneta gajajimana sp. nov., which was collected in Gajajima, Kagoshima-gun Toshimamura, Kagoshima Prefecture, Japan, on November 2012. The new species is characterized by its reddish brown to blackish brown body, smooth surface pronotum, well developed compound eyes, dark brown head apex, dark reddish brown front face and small white ocelli connected to the antennal sockets. In male, the tegmen tip reach the abdomen end or are slightly shorter, while in the female, it does not reach the abdominal end and exposes the abdomen beyond the 7th abdominal plate. We confirmed the validity of this new species by breeding the specimens in our laboratory to demonstrate that the features of the progeny were maintained for several generations. For comparison and easy identification of this new species, the key to species identification of the genus Periplaneta that had been reported in Japan to date are also presented.

Fulltext Azygos continuation of the inferior vena cava in carcinoma of oesophagus.

Mubarak, M.Y.

International Medical Journal Malaysia, 2008;7(2):57-61.

MyJurnal

The azygos system enlarges in cases of obstruction to the superior vena cava or inferior vena cava and result in increase blood flow through the system. Azygos continuation of the inferior vena cava is usually congenital and asymptomatic. The azygos vein is the sole drainage of the blood from the lower half of the body to the heart. It is crucial to identify the anomaly as it might involve in the surgical planning of tumours in the thorax or abdomen. Computed Tomography is a non-invasive technique and provide important information about the tumour and the vascular anomaly.

Chilaiditi's sign describes the incidental radiographic finding of the bowel positioned between the right diaphragm and the liver. This is often misdiagnosed as pneumoperitoneum or free air under the diaphragm, which may lead to unnecessary investigations or surgical procedures. Here, we report two incidental chest radiograph findings of air under the diaphragm in patients who were being screened for pulmonary tuberculosis. This case series highlights the importance of awareness of the diagnosis of Chilaiditi's sign to avoid unnecessary hospital referrals.

Fulltext Ectopic pregnancy following levonorgesterol-only emergency contraception: the first Malaysian case report

Natasha MN, Khoo HW, Sulaiman AS, Nur Azurah AG, Md Dali AZH, Jamil MA

Medicine & Health, 2012;7(2):107-111.

MyJurnal

Levonorgestrel (LNG) is a well-known safe and efficacious emergency contraception (EC). However, ectopic pregnancy following the failure of LNG-only EC has been reported. The exact incidence of ectopic pregnancy has been hindered by lack of data due to the fact that LNG-only EC is accessible at pharmacies without a prescription. We describe a case of ectopic pregnancy in an 18 year-old single woman who took LNG-only EC within 48 hours of unprotected sexual intercourse. She presented to the emergency department at 8 weeks period of amenorrhoea with an acute abdomen and hypovolaemic shock. Laparotomy confirmed a ruptured right tubal pregnancy and salpingectomy was performed. The patient was discharged well after 2 days. We aim to highlight this potential adverse effect and to discuss the plausible causality of ectopic pregnancy following administration of LNG-only EC.

Aortic malignant neoplasms are rare; these may be primary or secondary (metastatic). Increasing use of cross-sectional imaging has allowed better detection and diagnosis of these conditions. We encountered a young woman presenting with acute abdomen who was found on cross-sectional imaging to have a malignant tumor involving the aortic bifurcation. An en bloc excision of the tumor was performed, with distal aorta reconstruction using an aortoiliac Dacron graft; this was complicated with infection and graft occlusion, necessitating total removal and extra-anatomic bypass. A pathologic diagnosis of metastatic adenocarcinoma involving the aortic bifurcation, with an unknown primary, was made.

Correlation between Hounsfield unit derived from head, thorax, abdomen, spine and pelvis CT and t-scores from DXA

Amin MFM, Zakaria WMW, Yahya N

Skeletal Radiol, 2021 Dec;50(12):2525-2535.

PMID: 34021364 DOI: 10.1007/s00256-021-03801-z

OBJECTIVES: CT examination can potentially be utilised for early detection of bone density changes with no additional procedure and radiation dose. We hypothesise that the Hounsfield unit (HU) measured from CT images is correlated to the t-scores derived from dual energy X-ray absorptiometry (DXA) in multiple anatomic regions.

MATERIALS & METHODS: Data were obtained retrospectively from all patients who underwent both CT examinations - brain (frontal bone), thorax (T7), abdomen (L3), spine (T7 & L3) or pelvis (left hip) - and DXA between 2014 and 2018 in our centre. To ensure comparability, the period between CT and DXA studies must not exceed one year. Correlations between HU values and t-scores were calculated using Pearson's correlation. Receiver operating characteristic (ROC) curves were generated, and the area under the curve (AUC) was used to determine threshold HU values for predicting osteoporosis.

RESULTS: The inclusion criteria were met by 1043 CT examinations (136 head, 537 thorax, 159 lumbar and 151 left hip). The left hip consistently provided the most robust correlations (r = 0.664-0.708, p 0.05.

CONCLUSION: HU values derived from the hip, T7 and L3 provided a good to moderate correlation to t-scores with a good prediction for osteoporosis. The suggested optimal thresholds may be used in clinical settings after external validations are performed.

Changes in stroke volume variation and cardiac index during open major bowel surgery

Prabhu SP, Nileshwar A, Krishna HM, Prabhu M

Niger J Clin Pract, 2021 Nov;24(11):1682-1688.

PMID: 34782509 DOI: 10.4103/njcp.njcp_30_20

Background: Stroke volume variation (SVV) is a dynamic indicator of preload, which is a determinant of cardiac output. Aims: Aim of this study was to evaluate the relationship between changes in SVV and cardiac index (CI) in patients with normal left ventricular function undergoing major open abdominal surgery.

Patients and Methods: Patients undergoing major open abdominal surgery were monitored continuously with FloTrac® to measure SVV and CI along with standard monitoring. Both SVV and CI were noted at baseline and every 10 min thereafter till the end of surgery and were observed for concurrence between the measurements.

Results: 1800 pairs of measurement of SVV and CI were obtained from 60 patients. Mean SVV and CI (of all patients) measured at different time points of measurement showed that as SVV increased with time, the CI dropped correspondingly. When individual readings of CI and SVV were plotted against each other, the scatter was found to be wide, reiterating the lack of agreement between the two parameters (R2 = 0.035). SVV >13% suggesting hypovolemia was found at 207 time points. Of these, 175 had a CI >2.5 L/min/m2 and only 32 patients had a CI <2.5 L/min/m2.

Conclusion: SVV, a dynamic index of fluid responsiveness can be used to monitor patients expected to have large fluid shifts during major abdominal surgery. It is very specific and has a high negative predictive value. When SVV increases, CI is usually maintained. Since many factors affect SVV and CI, any increase in SVV >13%, must be correlated with other parameters before administration of the fluid challenge.

Salmonella enteritidis abdominal aorta mycotic aneurysm presented with acute cholestatic jaundice: A case report and literature review

Wahab AA, Mohamed N, Ding CH, Muttaqillah NAS, Rosli N, Mohammed F

Trop Biomed, 2023 Mar 01;40(1):23-28.

PMID: 37356000 DOI: 10.47665/tb.40.1.008

Mycotic aneurysm is one of the extra-intestinal manifestations of Salmonella Enteritidis infection. The diagnosis of this condition is challenging owed to its variation in clinical presentations. We presented a case of a 54-year-old man with underlying diabetes mellitus and chronic smokers presented with acute right flank pain and fever associated with mild jaundice. The initial laboratory investigations suggested features of obstructive jaundice and urinary tract infection. The contrast enhancing computed tomography of the abdomen revealed the presence of saccular mycotic aneurysm located at the infrarenal abdominal aorta. The blood culture grew Salmonella Enteritidis which was susceptible to ceftriaxone, trimethoprim-sulfamethoxazole, ciprofloxacin, ampicillin, and amoxicillin-clavulanic acid. Intravenous ceftriaxone was initiated, and he underwent open surgery and artery repair at day 8 of admission. He responded well to the treatment given and subsequently discharged home after completed three weeks of intravenous ceftriaxone.

In an infant presenting with a mass in the abdomen and non-bilious vomiting, duplication cyst needs to be considered in the list of differential diagnoses. Gastric duplication cyst is an uncommon occurrence in children. Diagnosis is based on clinical findings and imaging features. Surgical excision is safe and offers a complete cure. The literature recommends excision even in asymptomatic cases due to isolated reports of malignancy arising in the duplication cyst in later life.

Sze Li S, Kenneth Kher Ti V

Malays J Med Sci, 2012 Jan;19(1):69-72.

PMID: 22977378 MyJurnal

Obturator hernia is a rare condition that may present in an acute or subacute setting in correlation with the degree of small-bowel obstruction. Pre-operative diagnosis is difficult, as symptoms are often non-specific. A high index of suspicion should be maintained for emaciated elderly women with small-bowel obstruction without a previous abdominal operation and a positive Howship-Romberg sign. When diagnosis is in doubt, computed tomography scan of the abdomen and the pelvis (if available) or laparotomy should be performed immediately, as high mortality rate is related to the perforation of gangrenous bowels. We present 2 cases of strangulated obturator hernia, managed differently with both open and laparoscopic approaches. The diagnostic accuracy of computed tomography scan is highlighted followed by a brief literature review with an emphasis placed on surgical management.

The basis for the transversus abdominis plane (TAP) block involves infiltration of a local anesthetic into the neurofascial plane between the internal oblique and the transversus abdominis muscles, causing a regional block that spreads between the L1 and T10 dermatomes. Thus, the TAP block is said to be suitable for lower abdominal surgery. This study was designed to compare the analgesic efficacy of two different concentrations of ropivacaine for TAP block in patients undergoing appendectomy.
